Description

  The present invention is arranged in a boarding means such as a vehicle such as an automobile, a two-wheeled vehicle or an industrial machine, a small ship, a snowmobile, etc., and forms a predetermined electric circuit by turning on a tact switch, and the boarding means or the boarding means is provided. The present invention relates to an operating device for boarding means capable of operating the equipment to be operated.

  An industrial machine, for example, a construction machine (construction machine) is used at a civil engineering / architecture work site, and includes a bulldozer, a power shovel, and a crane truck. The driver's seat of such an industrial machine is generally provided with an operation lever that causes the industrial machine or equipment (option) included in the industrial machine to perform a predetermined operation by a swinging operation. A grip portion that can be gripped by an operator is formed on the protruding end side.

  Then, by swinging the operation lever while the operator holds the grip portion, an optional predetermined operation including, for example, traveling control of an industrial machine or a scraper can be performed. Recently, however, it has been proposed that an operation knob that can be operated by an operator is formed on the gripping part. The operator grasps the gripping part while holding the gripping part and swinging the operation lever. The operation knob can be operated by extending the length so that other operations can be performed.

  Such a conventional operation device includes a tact switch that can be turned on by operating the operation knob to form a predetermined electric circuit, and the tact switch forms a predetermined electric circuit, thereby allowing other operations of the industrial machine to be performed. (For example, the operation of changing the direction of the equipped scraper or performing a shift operation during traveling). In addition, since this prior art does not relate to the literature known invention, there is no prior art document information to be described.

  However, since the conventional operation device includes a tact switch that can be turned on by operating the operation knob, the stroke (displacement amount) of the operation knob cannot be set large, and the stroke is too small. There was a problem that the operability deteriorated. In other words, the tact switch is configured such that its operating part is pressed and displaced by the operation of the operation knob, and is turned on. However, the displacement amount of the operating part is set to be extremely small. Therefore, the stroke (displacement amount) of the operation knob must be reduced. If the stroke of the operation knob is small, a sufficient operational feeling cannot be obtained and the operability is deteriorated.

  On the other hand, if the stroke of the operation knob is set to be greater than or equal to the set displacement amount (displacement limit) of the operating unit, the tact switch may be destroyed when the operation knob is strongly pressed. In particular, in boarding means operating devices arranged on boarding means such as industrial machines, there are many operation knobs that are operated while performing other operations, and the lack of sufficient operational feeling significantly affects operability. In many cases, even if the stroke of the operation knob is set to be greater than or equal to the set displacement amount (displacement limit) of the operating part, the operation is strongly pressed beyond the displacement limit of the operating part. .

  The present invention has been made in view of such circumstances, and provides an operating device for riding means that can sufficiently obtain an operation feeling of an operation knob and can avoid destruction of a tact switch. is there.

The invention according to claim 1 is provided in the boarding means, and includes an operable operation knob, and an actuating portion that is pressed and displaced by operation of the operating knob, and can be turned on by displacement of the actuating portion. And an electric circuit board that forms a predetermined electric circuit when the tact switch is turned on and can operate the boarding means or the equipment included in the boarding means. with displacing and transmit force to the working portion of the tact switch and the actuating portion exceeds the displacement limit, comprising a transmission means capable of absorbing an amount of displacement of the operation knob, the transmission means, the tact A first operating member that can press the operating portion of the switch; a second operating member that abuts on a flange portion formed on the operating knob to receive operating force of the operating knob; the first operating member; An elastic member interposed between the two operating members, and when the operating portion exceeds a displacement limit, the elastic member compresses and the second operating member is relatively relative to the first operating member. It is configured to displace and absorb the displacement amount of the operation knob, and the flange portion is provided with a waterproof boot for covering the periphery of the operation knob and waterproofing .

According to a second aspect of the invention, the boarding unit operating device according to claim 1, wherein the elastic member has one end the first operating member abuts the other end while the second operating member and contact with the coil spring The spring load of the coil spring is set higher than the operation load on the operating part of the tact switch.

According to a third aspect of the present invention, in the riding means operating device according to the first or second aspect , the riding means has a predetermined one with respect to the industrial machine or equipment included in the industrial machine by a swinging operation. An operation lever for performing an operation, and a grip portion formed on a protruding end side of the operation lever that can be gripped by an operator to swing the operation lever, and the operation knob is formed in the grip portion. The operation is to cause the industrial machine or equipment included in the industrial machine to perform other predetermined operations.

  According to the first aspect of the present invention, the operating force of the operating knob is transmitted to the operating part of the tact switch and displaced, and when the operating part exceeds the displacement limit, the displacement amount of the operating knob can be absorbed. Since the transmission means is provided, it is possible to sufficiently obtain the operation feeling of the operation knob and to avoid the destruction of the tact switch. That is, the displacement of the operation knob can be set larger than the displacement limit of the operating portion of the tact switch by the transmission means, and the operation feeling of the operating knob can be sufficiently obtained, and the displacement limit of the operating portion of the tact switch can be obtained. Exceeding this causes the displacement of the operation knob to be absorbed, and the operation force is not transmitted to the tact switch, so that destruction of the tact switch is avoided.

Furthermore , when the actuating portion of the tact switch exceeds the displacement limit, the elastic member is compressed and the second operating member is displaced relative to the first operating member and absorbs the displacement amount of the operating knob. With a simple configuration in which one operation member, second operation member, and elastic member are interposed between the operation knob and the tact switch, it is possible to obtain a sufficient feeling of operation of the operation knob and avoid destruction of the tact switch. can do.

According to the invention of claim 2 , since the spring load of the coil spring is set higher than the operation load on the operating part of the tact switch, until the displacement limit of the operating part is exceeded (the operation process with a load smaller than the operating load) The coil spring is not compressed, and the operating force of the operating knob is transmitted to the operating part of the tact switch to displace it. When the operating part exceeds its displacement limit, the coil spring compresses and absorbs the displacement of the operating knob. Can do. Therefore, the actuating portion of the tact switch is not given more than the spring load of the coil spring, and destruction of the tact switch can be avoided reliably.

According to the invention of claim 3 , the operation knob is formed in the grip portion of the operation lever, and the operation causes the industrial machine or the equipment included in the industrial machine to perform a predetermined other operation. The effects of the inventions of claims 1 and 2 can be made more remarkable. That is, when the operation knob is formed in the grip portion of the operation lever in the industrial machine, it is necessary to give the operation feeling sufficiently because the operation knob is operated in addition to the swinging operation with respect to the operation lever, and In many cases, the operation knob is operated more strongly in order to maintain the gripping force with respect to the gripping portion, and it is necessary to avoid the destruction of the tact switch. Therefore, these needs can be sufficiently satisfied.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The boarding means operating device according to the present embodiment is disposed in an industrial machine (construction machine) such as a bulldozer, a power shovel, or a crane truck used in a civil engineering / architecture work site. As shown in FIG. 2, the operation knobs 4 and 18 are formed on the grip portion 2 on the protruding end side of the operation lever 1 disposed in the driver's seat of the industrial machine.

  The operating lever 1 includes a tubular member 2a that can swing around a swing shaft (not shown) at the base end (lower end side in the figure), and a corrugated tube 2b that is formed to cover the outer periphery of the tubular member 2a. Configured, and when the operator swings back and forth or from side to side, the industrial machine or equipment included in the industrial machine has a predetermined operation (for example, the industrial machine travels or stops, swivels, or It is configured to be able to operate an installed crane or excavator.

  The grip portion 2 is made of, for example, a resin molded product that can accommodate electric circuit boards 5, 12 and the like to be described later, and is configured so that an operator can grip and operate the operation lever 1 to swing. is there. On the front side (the side desired by the operator seated in the driver's seat) and the opposite side (back side) of the grip part 2, an operation that allows the operator holding the grip part 2 to operate by extending his / her finger Knobs 4 and 18 (switch knobs) are formed.

  Of these, the operation knob 4 is a so-called seesaw type switch knob that can be swung left and right by extending the operator's thumb. As shown in FIGS. It is formed in the case C1 while being covered and waterproofed. Further, as shown in FIGS. 6 and 7, the operation knob 4 is formed with flange portions 4a and 4b on the left and right sides, respectively. By pressing the left or right surface of the operation knob 4, the case C1 is attached to the case C1. When the formed swing shaft L is swung around, the flange portion 4a or 4b is configured to selectively press the operation portions Fa and Fb as transmission means in the case C1.

  The operation portion Fa is in contact with the first operation member 8a capable of pressing the operation portion 6aa of the tact switch 6a and the operation knob 4 (specifically, the flange portion 4a) and receives the operation force of the operation knob 4. And a coil spring 10a (elastic member) interposed between the first operation member 8a and the second operation member 9a. As shown in FIG. 4 is swung to the left and the flange portion 4a presses the top of the second operating member 9a, the pressing force is transmitted to the first operating member 8a via the coil spring 10a, and the tact switch 6a is covered with the packing 7a. The operation unit 7aa can be pressed.

  The coil spring 10a has one end in contact with the first operation member 8a and the other end in contact with the second operation member 9a, and the spring load of the coil spring 10a is the operation load on the operating portion 6aa of the tact switch 6a (that is, The biasing force of a spring or the like disposed in the tact switch 6a and returning the operating portion 6aa to its original position is set higher. Thereby, if the operation force by the operation knob 4 is less than or equal to the operation load of the operating portion 6aa (less than the limit displacement amount), the coil spring 10a is not compressed, and the operated portion 7aa of the packing 7a is pressed by the operation force. It will be.

  Similarly, the operation portion Fb abuts on the first operation member 8b that can press the operation portion 6ba of the tact switch 6b and the operation knob 4 (specifically, the flange portion 4b) to operate the operation knob 4. It comprises a second operating member 9b capable of receiving force, and a coil spring 10b (elastic member) interposed between the first operating member 8b and the second operating member 9b, and the operation knob 4 is on the right side. When the swinging operation is performed and the flange portion 4b presses the top of the second operating member 9b, the pressing force is transmitted to the first operating member 8b via the coil spring 10b, and the operated portion 7ba in the packing 7b of the tact switch 6b is transmitted. It can be pressed.

  Similarly to the coil spring 10a, the coil spring 10b has one end in contact with the first operating member 8b and the other end in contact with the second operating member 9b. The spring load of the coil spring 10b is the operating portion of the tact switch 6b. It is set higher than the operation load on 6ba (that is, an urging force such as a spring disposed in the tact switch 6b and returning the operating portion 6ba to its original position). Thereby, if the operation force by the operation knob 4 is less than or equal to the operation load of the operating portion 6ba (less than the limit displacement amount), the coil spring 10b is not compressed, and the operated portion 7ba of the packing 7b is pressed by the operation force. It will be.

  The packings 7a and 7b are made of soft resin or synthetic rubber, and are configured so as to cover the tact switches 6a and 6b and be waterproof, respectively. When the operating portions 7aa and 7ba are pressed by the first operating members 8a and 8b, they are elastically deformed, and the operating portions 6aa and 6ba of the internal tact switches 6a and 6b are pressed to turn on the tact switches 6a and 6b. To get. That is, it can be grasped which of the tact switches 6a and 6b is turned on whether the operation knob 4 is swung to the left or right.

  Here, in the present embodiment, the operation portions Fa and Fb as transmission means transmit the operation force of the operation knob 4 to the operation portions 6aa and 6ba of the tact switches 6a and 6b to displace them, and the operation portions 6aa and 6aa, When 6ba exceeds the displacement limit (that is, when the operation force by the operation knob 4 exceeds the operation load of the operating portion 6ba), the displacement amount of the operation knob 4 can be absorbed.

  That is, when the operating knob 4 is further swung from the state shown in FIG. 10 and the operating portion 6aa exceeds the displacement limit (when the operating force by the operating knob 4 exceeds the operating load of the operating portion 6ba). As shown in FIG. 11, the coil spring 10 a is compressed and the second operation member 9 a is displaced relative to the first operation member 8 a to absorb the displacement amount of the operation knob 4. The operation force of the operation knob 4 is not transmitted to the operation part 6aa. The same applies to the action of the coil spring 10b.

  With the above configuration, the amount of displacement due to the swinging operation of the operation knob 4 can be set larger than the displacement limit of the operating portion of the tact switch, and the operation feeling of the operation knob 4 can be sufficiently obtained, and the tact switch 6a, When the displacement limit of the operation portions 6aa and 6ba of 6b is exceeded, the operation portions Fa and Fb absorb the displacement of the operation knob 4 and the operation force is not transmitted to the tact switches 6a and 6b. Destruction can be avoided.

  Further, after the coil springs 10a and 10b are compressed and the second operation members 9a and 9b are displaced relative to the first operation members 8a and 8b, the second operation members 9a and 9b are shown in FIG. Thus, it contacts the step formed in the case C1. Thereby, it can avoid that the operation knob 4 further displaces exceeding the compression limit of the coil springs 10a and 10b, and presses the operation parts 6aa and 6ba of the tact switches 6a and 6b.

  However, when the pressing operation on the operation knob 4 is stopped and the operator releases the finger from the operation knob 4, the coil spring 10a or 10b is restored, and the second operation members 9a and 9b are relative to the first operation member 8aa. Urging force by a restoring means (not shown) such as a spring disposed in the tact switch 6a, 6b and returning the operating portion 6aa, 6ba to the original position, and elastic deformation The operating knob 4 is returned to the initial position (the state where it is not swung to the left or right) by the restoring force of the packings 7a and 7b.

  As shown in FIG. 7, the first operating member 8a is provided with a pair of flanges 8aa extending in the lateral direction from the circumferential surface thereof, and the first operating member 8a is operated by supporting the flanges 8aa on the case C1 side. The whole part Fa is prevented from coming off. Further, as shown in FIG. 8, the body portion of the second operation member 9a has a different shape (having a protruding shape in one direction), and is formed in the case C1 and has a shape corresponding to this body portion. By rotating the second operation member 9a through the insertion hole C1a (see FIG. 6), rotation of the entire operation portion Fa is stopped. About this structure, it is the same also about the operation part Fb, Furthermore, it is the same also about the operation part Fc mentioned later.

  Further, an electric circuit board 5 is disposed in the case C1 formed in the grip portion 3. As shown in FIG. 9, wiring K constituting the electric circuit is printed on the electric circuit board 5 and tact switches 6a and 6b are arranged. Control means arranged on the industrial machine main body side. (For example, ECU etc.) and the harness H can be electrically connected. Thus, the electric circuit board 5 forms a predetermined electric circuit corresponding to the swinging operation of the operation knob 4 and performs other predetermined operations (operation lever 1) with respect to the industrial machine or the equipment included in the industrial machine. For example, an operation for changing the direction of the scraper included in the industrial machine).

  Specifically, wiring K and tact switches 6a and 6b are formed on the surface (upper surface) of the electric circuit board 5 to constitute an electric circuit as shown in FIG. That is, it has a wiring L1 extending from a power source composed of a battery or the like mounted on an industrial machine, and wirings L2 and L3 branched from the wiring L1 and connected to tact switches 6a and 6b. When turned on, a predetermined circuit through which current flows through the wirings L1 and L2 is formed. For example, a scraper provided in an industrial machine is turned to the left side, and when the tact switch 6b is turned on, a predetermined circuit through which current flows through the wirings L1 and L3. For example, the scraper is directed to the right side.

  An overcurrent protection element 11 is formed on the back surface (lower surface) of the electric circuit board 5. The overcurrent protection element 11 refers to a device composed of a so-called polyswitch (polymer PTC thermistor), and the resistance value increases due to a temperature rise due to overcurrent, and the circuit current can be limited to suppress the overcurrent. At the same time, the change in the resistance value is made reversible so that the original resistance value can be returned to the original resistance value due to the decrease in temperature, and the circuit current limitation can be released (self-recovery can be performed).

  On the other hand, as shown in FIG. 3, the operation knob 18 is a so-called push-type switch knob that can be pressed by extending the index finger or middle finger of the operator. It is formed in the case C2 while being covered with the boot B2 and being waterproofed. Further, as shown in FIG. 12, the operation knob 18 is formed with a flange portion 18a. By pressing the surface of the operation knob 18, the operation knob 18 is immersed in the case C, and the transmission in the case C2 is performed. It is comprised so that the operation part Fc as a means may be pressed.

  The operation portion Fc contacts the first operation member 15 that can press the operation portion 13a of the tact switch 13 and the operation knob 18 (specifically, the flange portion 18a) and receives the operation force of the operation knob 18. And a coil spring 17 as an elastic member interposed between the first operation member 15 and the second operation member 16, and an operation knob as shown in FIG. When the flange 18 a presses the top of the second operation member 16 by the immersion operation 18, the pressing force is transmitted to the first operation member 15 via the coil spring 17, and the operated portion 14 a in the packing 14 of the tact switch 13. Can be pressed.

  The coil spring 17 has one end in contact with the first operation member 15 and the other end in contact with the second operation member 16, and the spring load of the coil spring 17 is an operation load on the operating portion 13 a of the tact switch 13 (that is, The biasing force of a spring or the like disposed in the tact switch 13 and returning the operating portion 13a to the original position is set higher. Thereby, if the operation force by the operation knob 18 is less than or equal to the operation load of the operating portion 13a (less than the limit displacement amount), the coil spring 17 is not compressed, and the operated portion 14a of the packing 14 is pressed by the operation force. It will be.

  The packing 14 is made of soft resin, synthetic rubber, or the like, and is configured to cover the tact switch 13 so as to be waterproof. As described above, the operated portion 14a formed at the center of the top is the first operation. When pressed by the member 15, it is elastically deformed, and the tact switch 13 can be turned on by pressing the operating portion 13 a of the internal tact switch 13. That is, whether or not the operation knob 18 has been pressed can be grasped by turning on the tact switch 13.

  Here, as with the operation units Fa and Fb, the operation unit Fc serving as a transmission means transmits the operation force of the operation knob 18 to the operation unit 13a of the tact switch 13 and displaces the operation unit 13a. If it exceeds (that is, if the operating force by the operating knob 18 becomes greater than or equal to the operating load of the operating portion 13a), the displacement amount of the operating knob 4 can be absorbed. That is, when the operation knob 18 is further pressed from the state shown in FIG. 13 and the operating portion 13a exceeds the displacement limit, the coil spring 17 is compressed and the second operation member 16 is compressed as shown in FIG. Is displaced relative to the first operating member 15 and absorbs the amount of displacement of the operating knob 18, so that the operating force of the operating knob 18 is not transmitted to the actuating portion 13 a of the tact switch 13. is there.

  With the above configuration, the displacement amount due to the pressing operation of the operation knob 18 can be set to be larger than the displacement limit of the operating portion in the tact switch, and the operation feeling of the operation knob 18 can be sufficiently obtained, and the operation of the tact switch 13 can be obtained. When the displacement limit of the portion 13a is exceeded, the operation portion Fc absorbs the displacement of the operation knob 18 and the operation force is not transmitted to the tact switch 13, so that the tact switch 13 can be prevented from being broken.

Further, after the coil spring 17 is compressed and the second operation member 16 is displaced relative to the first operation member 15, the flange portion 18a of the operation knob 18 is formed in the case C1, as shown in FIG. It contacts the stepped portion. Thereby, it is possible to prevent the operation knob 18 from being further displaced beyond the compression limit of the coil spring 17 and to avoid pressing the operating portion 13a of the tact switch 13.

  However, when the pressing operation on the operation knob 18 is stopped and the operator releases the finger from the operation knob 18, the coil spring 17 is restored and the second operation member 16 moves relative to the first operation member 15. By the biasing force by a restoring means (not shown) such as a spring which is disposed in the tact switch 13 and returns the operating portion 13a to the original position, and the restoring force of the elastically deformed packing 14 is returned to the original position. The operation knob 18 is returned to the initial position (a state where the operation knob 18 protrudes from the case C2 and can be pressed).

  Further, an electric circuit board 12 is disposed in the case C2 formed in the grip portion 3. Similar to the electric circuit board 5 in the case C1, the electric circuit board 12 is printed with wiring constituting the electric circuit and provided with a tact switch 13, and is disposed on the industrial machine main body side. It can be electrically connected to the means (for example, ECU) via the harness H. Thus, the electric circuit board 12 forms a predetermined electric circuit in response to the pressing operation of the operation knob 18, and performs other predetermined operations (the operation lever 1 and the operation lever 1 and the equipment included in the industrial machine). This is different from the operation by operating the operation knob 4, and is configured to allow, for example, shifting during traveling of an industrial machine.

  Specifically, as shown in FIG. 15, the electric circuit board 12 is provided with a wiring L4 branched from the wiring L3 formed on the electric circuit board 5 in the case C1, and the tact switch 13 is turned on. Then, a predetermined circuit flowing through the wirings L1 and L4 is formed, and, for example, a transmission provided in the industrial machine can be controlled to shift up or down. Thus, an overcurrent protection element 11 is connected in series to a predetermined circuit formed when the tact switch 13 is turned on, and the overcurrent protection element 11 is shared.

  According to this embodiment, when the operating portion of the tact switch exceeds the displacement limit, the elastic member is compressed and the second operation member is displaced relative to the first operation member, and the displacement amount of the operation knob is absorbed. Therefore, with a simple configuration in which the first operation member, the second operation member, and the elastic member are interposed between the operation knob and the tact switch, the operation feeling of the operation knob can be sufficiently obtained. The destruction of the switch can be avoided.

  Further, since the spring load of the coil spring as the elastic member is set higher than the operation load on the actuating part of the tact switch, the coil spring is not operated until the displacement limit of the actuating part is exceeded (the operation process with a load smaller than the operation load). Without being compressed, the operating force of the operating knob is transmitted to the actuating portion of the tact switch to be displaced, and when the operating portion exceeds the displacement limit, the coil spring can be compressed to absorb the displacement amount of the operating knob. Therefore, the actuating portion of the tact switch is not given more than the spring load of the coil spring, and destruction of the tact switch can be avoided reliably.

  Furthermore, the operation knob is formed in the grip portion of the operation lever, and the operation causes the industrial machine or the equipment included in the industrial machine to perform a predetermined other operation. be able to. That is, when the operation knob is formed on the grip portion 3 of the operation lever 1 in the industrial machine, the operation knob is operated in addition to the swinging operation with respect to the operation lever 1, so that it is necessary to have a sufficient operational feeling. In addition, the operation knob is often operated more strongly in order to maintain the gripping force with respect to the gripping portion 3, and it is necessary to avoid the destruction of the tact switch, so that these needs can be satisfied sufficiently.

Although the present embodiment has been described above, the present invention is not limited to this. For example, the present invention is applied to an operation device for other boarding means (vehicles such as automobiles, motorcycles, small ships, snowmobiles, etc.) instead of industrial machines. May be. Further, the transmission means that transmits the operating force of the operating knob to the actuating portion of the tact switch and displaces it and can absorb the displacement amount of the operating knob when the operating portion exceeds the displacement limit is the operating means of this embodiment. The present invention is not limited to the parts Fa and Fb, and various forms can be adopted.

  Further, when applied to an operation lever that can be swung as in the present embodiment, the present invention may be applied to one in which one operation knob is formed on the gripping portion of the operation lever, or three or more formed. . The form of the operation knob is not limited to the seesaw type or the push type as in the present embodiment, but may be one that can be operated by displacement (for example, a switch knob such as a slide type). Furthermore, the operation performed based on the operation by the operation knob is not limited to the operation as in the present embodiment, and may be other operations as long as the operation is performed by the boarding means or the equipment included in the boarding means. When applied to an industrial machine as in the present embodiment, it can be applied to various types such as a bulldozer, a scrape dozer, a hydraulic excavator (backhoe, power excavator, etc.), a truck with a crane device, and the like.

The operating force of the operating knob causes displacement is transmitted to the working portion of the tact switch and the actuating portion exceeds the displacement limit, comprising a transmission means capable of absorbing the displacement of the operation knob, the transmission means The first operating member that can press the operating part of the tact switch, the second operating member that can contact the flange formed on the operating knob and receive the operating force of the operating knob, the first operating member and the second An elastic member interposed between the operation members, and when the operating portion exceeds the displacement limit, the elastic member compresses and the second operation member is displaced relative to the first operation member, If it is configured to absorb the amount of displacement of the knob, and the operating device for the riding means is provided with a waterproof boot for covering the periphery of the operating knob and waterproofing the flange , the appearance shape is different.
