Description

  The present invention relates to a vehicle body contact avoidance device that is attached to a car wash machine and avoids contact between the car wash machine and the vehicle body. In addition, a contact sensor that can be installed in the vehicle body contact avoidance device, and a film used for the contact sensor Relates to a flexible substrate.

  After washing the car body with a car car washer, the car body is dried by moving the blower along the car body. The operation of this blower is determined based on the body shape read in advance, but if the vehicle slips due to rain or snow, the recorded shape may differ from the actual vehicle shape and the blower may collide with the vehicle body. It was. Therefore, installation of a sensor that detects a collision and stops the movement of the blower is required.

In a gate-shaped car wash machine that surrounds the left and right and upper sides of the vehicle body, an upper blower and left and right blowers are arranged, and the upper blower is provided with a ring-shaped detector (sensor) that surrounds the tip of the blower This ring is often used to detect contact with the vehicle body. On the other hand, left and right blowers often detect contact on their own.
For example, Japanese Patent Laid-Open No. 10-170861 (Patent Document 1) describes a ring-shaped sensor that senses the contact of the upper surface. Japanese Patent Laid-Open No. 2007-062545 (Patent Document 2) and 155538 (Patent Document 3) and JP 2012-148596 (Patent Document 4) describe a bar sensor for detecting side contact.

However, when the ring-shaped sensor is rubbed against the vehicle body or the blower comes into contact, the vehicle body may be slightly damaged. Therefore, a contact or non-contact sensor that does not damage the vehicle body is desired. However, since it may be difficult to detect with a non-contact sensor, a contact sensor capable of reliable detection and a sensor using the same are used. An object is to provide a vehicle body contact avoidance device.
Another object of the present invention is to provide a film-like flexible substrate used in the vehicle body contact avoidance device and the contact sensor.

  In order to achieve the above object, a vehicle body contact avoidance device for preventing contact between a car wash machine for washing a vehicle body and the vehicle body is formed in a cylindrical shape from a flexible thin film conductive rubber or a film-like flexible substrate having a conductive film. An outer peripheral part, a central part formed in a cylindrical shape with a film-like flexible substrate having a rod-like conductor or conductive film, and a fixing part for fixing the outer peripheral part and the central part. Detecting contact with the vehicle body by detecting capacitance change caused by a change in the relative position from the central portion when the outer peripheral portion comes into contact with the vehicle body or conduction due to contact between the outer peripheral portion and the central portion. A contact sensor and a blower provided in the car wash machine, in the vicinity of the tip of the blower in a direction in which the surface of the outer peripheral portion faces the traveling direction of the blower when the car wash machine operates. Providing body contact avoidance apparatus characterized by installing a serial contact sensor.

  Further, a contact sensor used in the vehicle body contact avoidance device, that is, a peripheral portion formed in a cylindrical shape from a film-like flexible substrate having a flexible thin-film conductive rubber or conductive film, and a rod-shaped conductive material or conductive film A central portion that is formed of a cylindrical film-like flexible substrate having a central portion located inside the outer peripheral portion, and a fixing portion that fixes the outer peripheral portion and the central portion, and the outer peripheral portion bends in contact with others Provided is a contact sensor that detects contact with another person by detecting a change in capacitance caused by a change in the relative position from the central part or conduction due to contact between an outer peripheral part and the central part.

Since such a contact sensor is used, the contact between the vehicle body and the contact sensor can be detected by deforming the outer peripheral portion of the vehicle body. Therefore, the position of the vehicle body can be sensed more reliably by contact with the contact sensor than in the case of non-contact.
Since the outer peripheral portion is made of a material that is flexible and easily deformed, the vehicle body is not damaged even if it comes into contact with the vehicle body. In addition, since it has a conductive part such as conductive rubber or conductive film, it can conduct through the outer periphery when detecting conduction, and when detecting a change in capacitance, it is grounded from the conductive part through wiring. be able to.

  Since the outer peripheral portion is formed in a cylindrical shape, it is relatively easy to adjust the length in the cylinder axis direction. For this reason, it is easy to meet the demand for a design that is long in the vehicle body width direction and compact in the vehicle length direction. Moreover, it is easy to detect when it is attached to a device that operates only in one axial direction, such as a car car washer, and contacts from one direction, and it is easy to detect even in two front and rear directions. And it is easy to form from planar materials, such as a thin film and a film, and manufacture is easy.

Since the central portion is located inside the outer peripheral portion, deformation like the outer peripheral portion is unlikely to occur, and since the central portion is protected by the outer peripheral portion, it is possible to increase the accuracy of detection of conduction and capacitance change.
If the central portion is a rod-shaped conductor, the contact sensor can be made compact and hardly deformed. Therefore, the size of the contact sensor can be reduced, and the detection accuracy can be maintained high.
If the central part is formed into a cylindrical shape with a film-like flexible substrate having a conductive film, even if the vehicle body or other contact objects contact not only the outer peripheral part but also the central part, the vehicle body or other The risk of damaging the contact object can be reduced.
Moreover, since the electroconductive part was provided in the center part, the electroconductivity by contact with an outer peripheral part and the electrostatic capacitance change by the outer peripheral part approaching can be transmitted.

Since the fixing part that fixes the outer peripheral part and the central part is provided, the outer peripheral part and the central part can be fixed to the fixing part to hold the shape, and the fixing part is attached to the object on which the contact sensor is installed. It is easy to install.
Since the contact sensor is installed in the direction in which the outer peripheral surface faces the direction of the blower when the car washer is in operation, the vehicle body should be applied substantially perpendicularly to the outer peripheral surface of the cylindrical outer peripheral portion. Can do. Therefore, the maximum displacement can be brought to the outer peripheral portion in the state where the outer peripheral portion and the vehicle body are in contact with each other, and the certainty of detection can be improved.
Moreover, since the said contact sensor was installed in the front-end | tip vicinity of a blower, a deformation | transformation of the contact sensor outer peripheral part by the air injection from a blower can be prevented. In other words, the vicinity of the tip of the blower here means the tip side of the blower excluding the most distal portion of the blower whose outer peripheral portion is affected by the air injection from the blower.

An insulating film covering a conductive part such as conductive rubber or a conductive film can be provided on the outer periphery of the contact sensor.
Since the insulating film covering the conductive portion is provided on the outer peripheral portion of the contact sensor, it is possible to prevent the conductive portion from coming into contact with water or a foreign substance and to detect the capacitance stably. Moreover, since the chemical resistance and durability with respect to the conductive portion are improved, the conductive portion can be protected from shampoo, wax, etc. for car washing, and the durability of the contact sensor can be enhanced.

A protective cover that covers the conductive portion and the insulating film and is exposed to the outside can be provided on the outer periphery of the contact sensor.
Since the outer periphery of the contact sensor is covered with a conductive part and insulating film and exposed to the outside, the film-like flexible substrate has a resistance to deformation and durability that the outer periphery does not deform under the influence of water pressure or wind pressure. Moreover, damage due to tearing or the like can be made difficult to occur in the film-like flexible substrate.

Both the outer peripheral portion and the central portion are formed in a cylindrical shape, and a contact sensor in which a part of the outer peripheral surface of the central portion and a part of the inner peripheral surface of the outer peripheral portion are fixed can be obtained.
Both the outer peripheral part and the central part are formed in a cylindrical shape, and the contact sensor is formed by fixing a part of the outer peripheral surface of the central part and a part of the inner peripheral surface of the outer peripheral part. Compared with the case where the is provided, the outer shape can be reduced, and the size of the contact sensor can be made compact. Moreover, it can produce from the sheet-like flexible substrate which continued the outer peripheral part and the center part.

  As a film-like flexible substrate serving as such a contact sensor, a film-like flexible substrate having the following configuration is provided. That is, it is a film-like flexible substrate for forming a contact sensor, and has a first adhesive portion on one end side of the back surface of a substantially rectangular resin film, and is adjacent to the first adhesive portion. A film having a second adhesive portion adhering to the first adhesive portion on the surface of the resin film adjacent to the central portion side conductive film, and adjacent to the second adhesive portion; Having a film, having a third adhesive portion adjacent to the outer peripheral side conductive film, having a connector portion at the other end of the resin film adjacent to the third adhesive portion, and the central portion side conductive It is a film-like flexible board which has the wiring which connects a film | membrane and the said connector part, and the wiring which connects the said outer peripheral part side electrically conductive film and the said connector part.

  According to such a film-like flexible substrate, since the outer peripheral portion and the central portion can be formed from one resin film, a compact and inexpensive contact sensor can be obtained.

  According to the vehicle body contact avoidance device, the contact sensor, and the film-like flexible substrate of the present invention, it is possible to prevent the car car washer from coming into contact with the vehicle body and damaging the vehicle body at the time of washing with the car car wash machine.

  The present invention will be described in more detail based on embodiments. About the site | part which is common in each following embodiment, the same code | symbol is attached | subjected and duplication description is abbreviate | omitted. In addition, overlapping descriptions of common materials, manufacturing methods, effects, and the like are omitted.

A contact sensor described as a specific embodiment will be described with reference to the drawings.
The contact sensor 11 shown in FIGS. 1 and 2 includes an outer peripheral portion 12, a central portion 13 positioned inside the outer peripheral portion 12, and a fixing portion 14 that fixes the outer peripheral portion 12 and the central portion 13. When the outer peripheral portion 12 bends due to contact with the vehicle body 2, the relative position from the central portion 13 changes, and a change in capacitance associated therewith or conduction due to contact between the outer peripheral portion 12 and the central portion 13 is detected. Thus, contact with the vehicle body 2 is avoided.

  The outer peripheral portion 12 has a cylindrical shape and is formed of a flexible thin film conductive rubber or a film flexible substrate having a conductive film. The cylindrical material made of conductive rubber or the flexible substrate in which a conductive film is formed on a film is formed into a cylindrical shape because it is bent when pressed by the vehicle body 2 and when the external force from the vehicle body 2 is removed. This is because it has the flexibility to return to its shape.

As the conductive rubber, a conductive polymer, a synthetic rubber mixed with a conductive medium, or a synthetic rubber formed with a conductive film such as a metal film or a conductive film can be used. As the film-like flexible substrate having a conductive film, a resin film in which a conductive film such as a conductive polymer, a metal film, or a conductive coating film is formed can be used.
FIG. 3 shows an example of a film-like flexible substrate 12a having a conductive film. This film-like flexible substrate 12a is formed by printing a conductive film 12c with conductive ink and a wiring 12d with silver paste on a resin film 12b, and the wiring 12d connects the conductive film 12c and the connector portion 12e. The connector part 12e is connected to a fixing part 14 to be described later, and is further connected from the fixing part 14 to an analysis circuit part (not shown) having an IC chip for analyzing a detection signal.
In addition, what is necessary is just to form the whole except for the connector part of a film-like flexible substrate with conductive rubber, when using conductive rubber.

In order to form the outer peripheral portion 12 in a “cylindrical shape”, it is formed into a flat plate shape as shown in FIG. 3, bent into a cylindrical shape, and bonded to the end portion to form a cylindrical shape. it can. Alternatively, a conductive rubber or resin film itself formed into a cylindrical shape can be used.
Regardless of whether the conductive rubber or the flexible substrate is used, the conductive portion is provided on the entire outer peripheral portion 12 or a part of the outer peripheral portion 12 so that the conductive portion is brought into contact with the central portion 13, and the conductive portion is static even without contact. A change in electric capacity can be detected by a continuous analysis circuit unit. Moreover, since it formed in the cylinder shape, it becomes possible to detect pushing by the vehicle body 2 from multiple directions.

The central portion 13 is formed of a rod-shaped conductor or a cylindrical film-shaped flexible substrate having a conductive film.
As the rod-shaped conductor, a metal or conductive rubber formed in a rod shape can be used. In addition, a cylindrical film-like flexible substrate having a conductive film is formed by forming a flexible substrate in a cylindrical shape small enough to fit inside the outer peripheral portion 12, and the conductive film can be a conductive polymer, a metal film, or a conductive material. It can be formed with a coating film or the like.
FIG. 4 shows an example of a film-like flexible substrate 13a having a conductive film. The film-like flexible substrate 13a can also have the same configuration as the film-like flexible substrate 12a that forms the outer peripheral portion 12. That is, the conductive film 13c is printed on the resin film 13b with conductive ink and the wiring 13d is printed with silver paste, and the wiring 13d connects the conductive film 13c and the connector portion 13e. The connector portion 12e is connected to a fixing portion 14 to be described later, and is further connected from the fixing portion 14 to an analysis circuit portion (not shown) having an IC chip for analyzing a detection signal.

  The conductive portions of the outer peripheral portion 12 and the central portion 13 can be formed as a circuit in addition to the conductive film formed in an electrode shape and wiring that leads to the connector portions 12e and 13e. However, since it is preferable to detect the change in capacitance through the central portion 13, the function as the detection electrode is preferably provided in the central portion 13 and the function as the ground electrode is preferably provided in the outer peripheral portion 12. Therefore, it is a preferable aspect that the conductive film in the central portion 13 is configured as a detection electrode. In addition, an electrode other than the detection electrode for compensating for environmental characteristics and a circuit connecting them are provided in the central portion 13. Providing is also a preferred embodiment.

  The reason why it is preferable to detect the capacitance change through the central portion 13 is that if it is performed through the central portion 13, it is easy to detect the capacitance change due to the bending of the outer peripheral portion 12. On the other hand, if it is attempted to detect a change in capacitance from the outer peripheral portion 12, there is a possibility that the outer peripheral portion 12 may react when an object other than a vehicle, water droplets, or the like touches it.

In the case of detecting a change in capacitance due to the proximity of the outer peripheral portion 12 and the central portion 13 without performing detection due to contact between the outer peripheral portion 12 and the central portion 13, the conductive films 12c provided on the resin films 12b and 13b, 13c can be covered with insulating films 12f and 13f (see FIG. 5).
By covering the conductive films 12c and 13c with the insulating coatings 12f and 13f, the conductive films 12c and 13c are prevented from coming into contact with water and foreign matters, and stable capacitance detection is possible. In addition, chemical resistance, durability, and the like for the conductive films 12c and 13c are improved. Such insulating films 12f and 13f can be formed of a resist member such as a resin coating film.

  A protective cover 12g can be provided on the outermost surface of the outer peripheral portion 12 (see FIG. 5). By providing the protective cover 12g, the flexible substrate 12a can be prevented from being damaged, and deformation of the outer peripheral portion 12 due to water pressure or wind pressure can be avoided. The protective cover 12g can be formed of a rubber member or a soft resin member.

  The fixing part 14 is connected to the outer peripheral part 12 and the central part 13 to fix them. On the other hand, the fixing part 14 is also a fixing part to the attachment object of the contact sensor 11. The fixing part 14 can be made of resin or metal. If a hard resin is used as the material, connection portions for connecting the connector portions 12e and 13e of the film-like flexible boards 12a and 13a forming the outer peripheral portion 12 and the central portion 13 can be easily provided, and the car car washer 1 The shape and form can be easily connected to the left and right blowers 3.

  The shape of the fixing portion 14 can be made into a shape that is easy to handle as appropriate in accordance with the shape of the object on which the contact sensor 11 is installed. FIG. 1 shows a plate-like outer peripheral side fixing portion 14a for fixing the outer peripheral portion 12, a plate-like central portion fixing portion 14b for fixing the central portion 13, and a plate shape connecting the centers of the two. The connecting portion 14c is a fixed portion 14 that is H-shaped in plan view. Since the connection part 14c should just connect the outer peripheral part side fixing | fixed part 14a and the center part side fixing | fixed part 14b, it is a rod shape which connects one end with the outer peripheral part side fixing part 14a and connects the other end with the central part side fixing part 14b. Etc.

6 and 7 show examples in which the shape of the fixing portion is changed in addition to the above. In the contact sensor 11a shown in FIG. 6, the fixing part 14 is substantially trapezoidal in plan view, and in the contact sensor 11b shown in FIG. 7, the outer peripheral side fixing part 14a and the central part side fixing part 14b are connected. This is an example in which the connecting portion 14c is formed of a coil spring.
In the fixed portion 14 of the contact sensor 11a, a circuit or an electronic component serving as an analysis circuit portion can be incorporated with the inside as a cavity. Moreover, in the fixing part 14 of the contact sensor 11b, the center side fixing part 14b is also easily changed, and even if the vehicle body 2 contacts the center part 13, damage to the vehicle body 2 due to the contact can be suppressed. it can.

A contact sensor 11c shown in FIG. 8 has a fixed portion 14 that is substantially L-shaped in plan view.
Since the fixing portion 14 is substantially L-shaped, the space formed by the outer peripheral portion 12 and the central portion 13 can be reduced. Furthermore, the outer peripheral portion 12 and the central portion 13 can be easily attached to the fixed portion 14, and the fixing strength can be increased.
The contact sensor 11d shown in FIG. 9 is an example in which the central portion 13 is formed of a metal that is a rod-shaped conductor, and the central portion 13 is not deformed even under harsh conditions, thereby providing more precise sensitivity. be able to.

In the contact sensor 11e shown in FIG. 10, both the outer peripheral portion 12 and the central portion 13 are formed in a cylindrical shape, and a part of the outer peripheral surface of the central portion 12 and a part of the inner peripheral surface of the outer peripheral portion 13 are fixed. It is composed.
In the contact sensor 11e, the outer peripheral portion 12 and the central portion 13 are formed by a film-like flexible substrate 16 made of a single resin film. As shown in FIG. 11, a first adhesive portion 16h is formed on one end side of the back surface 17b of the substantially rectangular resin film 16b, and a central-side conductive film 16i is formed adjacent to the first adhesive portion 16h. Then, a second adhesive portion 16j to which the first adhesive portion 16h is bonded is formed on the surface 17a of the resin film 16b adjacent to the central portion side conductive film 16i, and adjacent to the second adhesive portion 16j. The outer peripheral portion side conductive film 16k is formed, the third adhesive portion 16p is formed adjacent to the outer peripheral portion side conductive film 16k, and the connector portion 16f is adjacent to the third adhesive portion 16p on the other end of the resin film 16b. And a wiring 16d1 connecting the central side conductive film 16i and the connector part 16f and a wiring 16d2 connecting the outer peripheral side conductive film 16k and the connector part 16f are formed.

  In order to form the outer peripheral portion 12 and the inner peripheral portion 13 from the flexible substrate 16, first, the first adhesive portion 16 h and the second adhesive portion 16 j are bonded by rounding from the first adhesive portion 16 h side, and this is further rounded. The third bonding portion 16p is bonded to the overlapping portion of the lever. In this way, the outer peripheral part 12 and the center part 13 of the contact sensor 11d shown in FIG. 10 can be obtained. Thereafter, the connector portion 16f is connected to a predetermined portion of the fixing portion 14, and is fixed to the fixing portion 14 at a portion corresponding to the third adhesive portion 16p of the outer peripheral portion 12.

  An insulating film (not shown) can be provided on the conductive portions such as the conductive films 16i and 16k and the wirings 16d1 and 16d2 on the front surface 17a and the back surface 17b of the resin film 16b. The outside of the part 12 can be covered with a protective cover (not shown).

  As the car car wash machine 1, a generally known car car wash machine 1 can be used, and in particular, the contact sensor 11 can be suitably used for the gate type car car wash machine 1 that automatically operates before and after the vehicle body 2.

FIG. 12 shows an example of a vehicle body contact avoidance device in which the contact sensor 11 is attached to the left and right blowers 3 of the car wash machine 1. In this example, the contact sensor 11 is provided in the left and right blowers 3 that blow air to the side surface of the vehicle body 2, and in the unlikely event that the fender mirror 2 a of the vehicle body 2 comes into contact with the contact sensor 11, it is detected.
When the contact sensor 11 is attached to an installation object such as the left and right blower 3, the direction of the contact object (the fender mirror 2 a of the vehicle body 2) is in contact with the surface of the outer peripheral portion 12 substantially perpendicularly. It is preferable to attach the contact sensor 11 to an installation object. Therefore, when attaching to the left and right blowers 3 of the car wash machine 1, the outer peripheral portion with respect to the traveling direction of the left and right blowers 3 (the front and rear direction of the vehicle body 2) near the tips of the left and right blowers 3 while avoiding the air outlet 3 a. It is preferable to install so that the surface of 12 may oppose. However, if it is installed at the forefront of the left and right blowers 3, it is required to avoid the influence on the detection due to the vibration of the left and right blowers 3 and the influence of the flexible substrate 12a being caught and deformed by air injection.

FIG. 13 shows another example of the vehicle body contact avoidance device in which the contact sensor 11 is attached to another upper blower 4 of the car wash machine 1.
In this example, the contact sensor 11 is provided in the upper blower 4 that blows air on the upper surface of the vehicle body 2, and in the unlikely event that the windshield 2 c of the vehicle body 2 comes into contact with the contact sensor 11, it is detected.
Also in this vehicle body contact device, the upper blower in which the contact object (the windshield 2c of the vehicle body 2) is in contact with the surface of the outer peripheral portion 12 substantially perpendicularly and avoids the air outlet 4a of the upper blower 4. 4 is installed in the vicinity of the tip.

  According to such a vehicle body contact avoidance device and the contact sensor 11 incorporated therein, the flexible substrate 12a is flexible and flexible, so that it is difficult to damage the vehicle body 2. Further, if the central portion 13 is also formed of the flexible substrate 13a, the central portion 13 can also be bent, and the vehicle body 2 will collide with the contact sensor 11 vigorously, and the car washing machine 1 can be stopped only by the deformation of the outer peripheral portion 12. Even if the vehicle body 2 is in contact with the central portion 13, the vehicle body 2 can be prevented from being damaged by the deformation of the central portion 13.

  The above embodiment is an example of the present invention, and the present invention is not limited to such a form, and includes modifications of the shape, material, manufacturing method, and the like of each member as long as not departing from the spirit of the present invention. For example, although the contact sensor is used in a car wash machine, it can also be used with other devices and can be used to detect contact with an object other than the vehicle body.
