JP6822738B2 - Security switch mounting structure - Google Patents

Description

The present invention relates to a security switch mounting structure used for vehicle theft prevention, and more particularly to a security switch mounting structure that makes it difficult to approach the security switch from outside the vehicle.

Cars are not always stored on private property, only in locked buildings. If used normally, it is often temporarily parked on public roads or in outdoor parking lots. In other words, there is an opportunity to be left unattended. Therefore, the owner needs to take measures against the risk of vehicle theft.

Many proposals have been made for vehicle anti-theft systems. Many of these proposals detect the act of someone other than the user trying to open the door or open the hood. Especially when the hood is opened, the engine room can be accessed directly, so many functions such as the engine, battery and control device can be hijacked and the vehicle can be stolen. Therefore, the hood opening / closing mechanism is equipped with a security switch that detects an abnormal opening of the hood when a person other than the user opens the hood without permission.

For example, Patent Document 1 describes that a bonnet switch for detecting an open / closed state of a bonnet hood of a vehicle is used as a means for detecting fraudulent activity.

This bonnet switch is also called a hood switch. Here, it is called a security switch. The security switch is disclosed in Patent Document 2. This is a type of switch that turns on and off when the shaft urged by the spring moves up and down.

Using a security switch to detect the open / closed state of the hood is cost effective because it has a simple configuration. However, such a push-type switch could be released when approached through a gap for air intake between the bumper and the engine hood.

FIG. 8 shows a case where the pressing surface 24 of the security switch 10 can be seen through the gap 40 between the bumper 30 and the hood 20. More specifically, there is nothing blocking the virtual straight line 42 on the virtual straight line 42 drawn linearly from the gap 40 to the pressing surface 24 of the security switch 10. With such a configuration, the security switch 10 can be approached from the gap 40, and the hood 20 may be opened while the security switch 10 is held down.

The present invention has been conceived in view of the above problems, and provides a security switch mounting structure that cannot be approached from the outside even if a push-type security switch is used.

More specifically, the security switch mounting structure according to the present invention is
It is a security switch mounting structure consisting of a security switch installed in the engine room and a pressing surface formed on a hood inner that presses the security switch.
A part of the structure of the bumper or the hood exists on a virtual straight line drawn linearly from the outside of the vehicle to the pressing surface formed on the hood inner through the opening between the closed hood and the bumper.
The pressing surface is the back side of an opening formed in the facing surface of the hood inner facing the security switch, and is between the facing surface and an inclined surface of the hood inner provided behind the facing surface or from the facing surface. It is formed in a reinforce provided in the vicinity thereof, recessed from the facing surface.
The recess is characterized in that it has a size and a depth into which the entire circumference of the tip of the security switch can be inserted.

In the security switch mounting structure according to the present invention, a part of the structure of the bumper or the hood is formed on a virtual straight line drawn linearly from the gap between the hood and the bumper to the pressing surface of the security switch formed on the hood inner. Due to its presence, the security switch cannot be approached through the gap between the hood and the bumper. Therefore, there is an effect that the robustness of the anti-theft system is improved.

It is a semi-perspective view of the vehicle which provided the security switch mounting structure which concerns on this invention. It is a figure which shows the AA cross section of FIG. It is a figure which shows the other embodiment. It is a figure which shows the other embodiment. FIG. 4 is a view when viewed from bottom to top. It is a figure which shows the modification of FIG. It is a figure which shows the modification of FIG. It is a figure which shows the conventional example.

The security switch mounting structure according to the present invention will be described below with reference to the drawings. The following description illustrates one embodiment of the present invention, and the present invention is not limited to the following description. Therefore, the following description can be modified without departing from the spirit of the present invention. In the present specification, the arrow F indicates the vehicle front direction, the arrow R indicates the vehicle rear direction, and the arrow D indicates the lower side in the gravity direction.

FIG. 1 shows the front part of an automobile having the security switch mounting structure 1 according to the present invention. In the security switch mounting structure 1 according to the present invention, the security switch 10 is mounted on the upper portion 50 of the radiator support at the front portion of the vehicle. The hood 20 is attached to the windshield 52 side with a hinge (not shown).

Therefore, the opening / closing stroke of the hood 20 is large on the bumper 30 side. It is preferable that the push-type security switch 10 is attached to a portion of the hood 20 having a large opening / closing stroke because it can detect even if the hood 20 is slightly opened.

FIG. 2 shows a cross section taken along the line AA of FIG. The security switch 10 is attached to the upper portion 50 of the radiator support. When the hood 20 is closed, the pressing surface 24 of the security switch 10 provided on the hood inner 22 presses the security switch 10.

On the other hand, a gap (opening) 40 for taking in outside air is formed between the hood 20 and the bumper 30. This is for cooling the engine room. If the pressing surface 24 of the security switch 10 can be seen through the gap 40, the pressing surface 24 can be approached using some kind of jig, and the hood 20 can be opened while the security switch 10 is pressed. In some cases. That is, the hood 20 can be opened and the engine room can be touched as a fraudulent act.

However, in the security switch mounting structure 1 according to the present invention, a part of the structure of the bumper 30 or the hood inner 22 is present on the virtual straight line 42 drawn linearly from the gap 40 to the pressing surface 24 of the security switch 10. That is, the pressing surface 24 is made invisible through the gap 40. In FIG. 2, the step 22a of the hood inner 22 exists on the virtual straight line 42. Therefore, the pressing surface 24 of the security switch 10 cannot be seen, and the pressing surface 24 cannot be approached.

FIG. 3 shows a case where the pressing surface 24 is set at a higher position with respect to the gap 40. Also in this case, a part 22b of the structure of the hood inner 22 exists on the virtual straight line 42 drawn linearly to the pressing surface 24 through the gap 40, and the pressing surface 24 cannot be directly approached from the gap 40.

The gap 40 between the bumper 30 and the hood 20 has a length as long as the width of the hood 20 (see 40w in FIG. 1). Therefore, even if the pressing surface 24 of the security switch 10 cannot be seen through the gap 40 from one direction, if it can be seen from the other direction, the security switch 10 is still forcibly pressed.

Therefore, in the present invention, the virtual straight line 42 drawn linearly to the pressing surface 24 through the gap 40 means a virtual straight line drawn from all directions of the gap 40 to the pressing surface 24. In other words, the present invention makes the pressing surface 24 invisible from all directions through the gap 40. Therefore, the structure of the bumper 30 and the hood inner 22 that block the virtual straight line 42 between the gap 40 and the pressing surface 24 does not have to be one. A plurality of structures of the bumper 30 and the hood inner 22 may be located between the gap 40 and the pressing surface 24.

FIG. 4 illustrates another embodiment. The hood inner 22 is formed with a surface 25 facing the security switch 10. Then, the pressing surface 24 of the security switch 10 is formed on the facing surface 25. At that time, the pressing surface 24 is recessed with respect to the facing surface 25. That is, when viewed in the direction of gravity, the pressing surface 24 of the security switch 10 is formed above the facing surface 25 of the security switch 10 in the direction of gravity.

By forming the hood inner 22 in such a structure, the pressing surface 24 of the security switch 10 is hidden by the facing surface 25 of the security switch 10, and the pressing surface 24 of the security switch 10 can be seen from any direction of the gap 40. Can be eliminated.

FIG. 5 shows a view of FIG. 4 from another accuracy. The security switch 10 has a rubber cap 10b that is placed on a shaft 10a that moves up and down by pressing, a skirt portion 10c that serves as a stopper when the security switch 10 is attached to the upper portion 50 (see FIG. 4) of the radiator support, and the like. In FIG. 5, the portion below the skirt portion 10c (in the direction of arrow D) is housed in the upper portion 50 of the radiator support.

The surface 25 of the hood inner 22 facing the security switch 10 refers to an area of about 3 to 4 times the area projected on the hood inner 22 by the skirt portion 10c of the security switch 10.

A plane is formed in this region as the facing surface 25. Then, a pressing surface 24 for pressing the rubber cap 10b of the security switch 10 is formed on the facing surface 25. At this time, the pressing surface 24 is formed so as to be recessed upward from the facing surface 25 in the direction of gravity.

FIG. 6A shows a modified example of FIG. FIG. 6B is a partially enlarged view of FIG. 6A. Note that the security switch 10 is omitted in FIG. 6B. In FIG. 4, the hood inner 22 itself is deformed to form the pressing surface 24. In FIG. 6, an opening 22h is provided in the hood inner 22 on the facing surface 25 of the security switch 10, and the reinforcement 26 is joined to the back side of the hood inner 22. The reinforce 26 has a cross-sectional hat shape having a joint flange surface 26a, a vertical wall 26b, and a web 26c.

The joining flange surface 26a is joined to the back side of the hood inner 22. Therefore, the inner side surface of the web 26c faces the opening 22h and becomes the pressing surface 24.

With such a shape, a distance is formed between the joint flange surface 26a and the pressing surface 24, and the pressing surface 24 is hidden by the facing surface 25 and becomes invisible. In other words, the facing surface 25 exists between the gap 40 formed by the bumper 30 and the hood 20 and the pressing surface 24.

Further, if the reinforce 26 is provided on the back surface of the hood inner 22, the strength of the hood inner 22 and the hood 20 itself will be improved.

FIG. 7A shows a further modification of FIG. FIG. 7B is a partially enlarged view of FIG. 7A. The security switch 10 is omitted. FIG. 7 shows a case where the inclined surface 22s is formed on the hood inner 22. The reinforce 27 has a shape in which one vertical wall and the web are continuous in a plane. That is, it is composed of a joint flange surface 27a, a vertical wall 27b, and a flat surface portion 27d in which the web and one vertical wall are combined.

As in the case of FIG. 6, the reinforce 27 is attached by providing an opening 22h adjacent to the inclined surface 22s of the hood inner 22 and connecting the inner flat portion 27d of the reinforce 27 so as to face the opening 22h on the back side thereof. To do. At this time, since the reinforce 27 connects the inclined surface 22s of the hood inner 22 and the flat facing surface 25, it is more effective in improving the rigidity of the hood inner 22.

Even in the configuration of FIG. 7, the pressing surface 24 is composed of a flat portion 27d inside the reinforce 27. Therefore, the facing surface 25 of the security switch 10 is always present on the virtual straight line 42 drawn linearly from the gap 40 between the bumper 30 and the hood 20 to the pressing surface 24.

As described above, the security switch mounting structure of the present invention has a structure that is hard to be stolen even if the security switch is arranged at a position close to the bumper. Although the above description has been given for an automobile having an engine room in front of the vehicle, the same can be applied when the engine room is in the rear of the vehicle.

The security switch mounting structure according to the present invention can be suitably used for an automobile having a structure in which an engine room is covered with a hood.
