Description

Detailed Description of the Invention [Industrial Application Field 1] The present invention relates to a handle switch for an automobile door that electrically unlocks the automobile door from inside or outside the automobile. equipment, e.g.
This is used in power latch release type door lock devices, etc.

[Prior Art 1] A conventional handle switch for the automatic inner door of this scale is shown in the perspective view from the back of FIG. 4.

In the figure, a handle switch for an automobile door includes a case 1, a handle (not shown) attached to a handle arm 2, fulcrums @3a and 3b that support the case 1 and the handle arm 2, and a handle arm 2. counterweight 4 attached to the opposite end of the handle of
, a spring 5 that is inserted into the fulcrum shaft 3a and provides elasticity between the handle arm 2 and the case 1, and an opening switch 6 that is switched by operating the handle.

Then, when the handle is pulled, the handle arm 2 rotates around the fulcrum shaft 3a and the fulcrum shaft 3b, and the counterweight 4 operates the opening switch 6. When the opening switch 6 is actuated, an exciting current flows through the electromagnetic solenoid constituting the unillustrated 7 quiter.
The plunger drives the open lever,
The ratchet pole is pulled up, the ratchet ball is released, and the door is opened.

However, with this type of handle switch for an automobile door, there is a possibility that the opening switch may be pressed and the automobile door opened due to the vibration of the vehicle or the load on the handle when turning. In particular, when turning at high speed, the influence of centrifugal force in the direction of pulling the steering wheel cannot be ignored.

In order to solve this problem, methods such as increasing the weight of the counterweight 4 or increasing the elastic force of the spring 5 can be considered. However, there is a limit to how far C can be lifted with the counterweight 4, and the weight can only be added until a balance is achieved between the handle side from the fulcrum shafts 3a and 3b and the counterweight 4 side from the fulcrum shafts 3a and 3b. It is something.

Therefore, if the elastic force of the spring 5 is further increased to cope with the problem, the steering becomes difficult to operate, which poses a problem in operability.

In addition, as a countermeasure to the above problems,
It is also conceivable to use the structure of a handle switch for an automobile door shown in FIG. 2 of Japanese Patent No. 9457. but,
The above structure has an operating lever inside the handle, and the load on the operating lever produces the same result as the handle and handle arm of the conventional embodiment. There was a possibility that the hand could get caught between the lever and the lever.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned problems and provide a safe handle switch for automobile doors that does not cause malfunctions when the vehicle vibrates or turns.

[Means for Solving the Problems] A handle switch for an automobile door according to the present invention includes a case in which a handle portion of a handle switch provided on an automobile door is integrally formed, and a switch housing made of an elastic body. The handle is equipped with a pressure-sensitive switch, and the pressure-sensitive switch is attached to the back side of the handle portion using attachment means.

[Function] In the present invention, a pressure-sensitive switch is inserted into a switch housing made of an elastic body with respect to a case in which a handle portion of a handle switch provided on an automobile door is integrally formed, and the pressure-sensitive switch is inserted into a switch housing made of an elastic body. By attaching the switch to the back of the handle, it forms a handle switch for automatic inner doors. Therefore, when you insert your hand into the handle and pull the handle toward you, you press the pressure-sensitive switch, which turns on. Then, by releasing the pressing force on the pressure-sensitive switch, the operation of the pressure-sensitive switch is stopped. In this way, when the pressure-sensitive switch is directly attached to the back surface of the handle portion, the load is smaller than that of the conventional handle and handle arm, and malfunction of the switch due to inertia can be prevented. In addition, since there is no need to put the handle in a vJ state as in the conventional case, the handle portion and the case can be formed integrally, which is advantageous in terms of cost.
