The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1-5, the present invention provides a central lock switch for a vehicle, which comprises a base 1, a housing 2 disposed on the base 1, and a driving panel 3 rotatably connected to the housing 2, wherein the driving panel 3 is provided with a locking button 31 and an unlocking button 32.

Specifically, the driving panel 3 is provided with rotating shaft holes 34 at both sides, and the housing 2 is provided with rotating shafts 21 inserted into the rotating shaft holes 34, so as to rotatably connect the driving panel 3 to the housing 2.

Referring to fig. 1 again, the housing 2 is provided with a top rod 4 at the position corresponding to the locking button 31 and the unlocking button 32; the base 1 is provided with a circuit board 5, and a touch switch 51 is arranged on the circuit board 5 corresponding to the position of the ejector rod 4. When the locking button 31 or the unlocking button 32 is pressed, the ejector rod 4 can be driven to move downwards and the tact switch 51 is switched on, so that locking or unlocking is realized; when the lock button 31 or the unlock button 32 is released, the tact switch 51 rebounds and moves the plunger 4 upward, and resets the lock button 31 or the unlock button 32. The fitting surfaces of the locking button 31 and the unlocking button 32 with the jack 4 are both arc surfaces.

Specifically, the locking button 31 and the unlocking button 32 are both provided with a convex strip 33 on one side facing the ejector rod 4, and the convex strip 33 is provided with a circular arc surface 331; when the locking button 31 or the unlocking button 32 is pressed, the arc surface 331 of the protruding strip 33 is driven to contact with the top rod 4, and the top rod 4 is driven to move. The shell 2 is provided with a limit hole 22 for the push rod 4 to insert into, and when the push rod 4 is inserted into the limit hole 22, the movement of the push rod 4 in the horizontal direction can be limited. Thus, when the button is pressed, the jack 4 can only move up and down.

Therefore, when the locking button 31 or the unlocking button 32 on the driving panel 3 is pressed, the matching surface of the locking button 31 or the unlocking button 32 and the ejector rod 4 is an arc surface, so that the locking button 31 or the unlocking button 32 and the ejector rod 4 are always in a contact state, the operation hand feeling of the button is ensured, and the operation comfort is improved.

Referring to fig. 1, 4 and 5, the housing 2 is provided with a fastening hole 23, and the base 1 is provided with a fastener 11 fastened in the fastening hole 23; the snap hole 23 is a blind hole. The housing 2 is further provided with a plurality of grooves (not shown), and the base 1 is provided with protrusions 12 inserted into the grooves.

Thereby, when the buckle 11 on the base 1 is clamped into the buckle hole 23 on the shell 2, the movement of the base 1 in the vertical direction is limited; when the projection 12 on the base 1 is inserted into the groove, the horizontal movement of the base 1 is limited; in addition, the fastening hole 23 is set to be a blind hole, so that the dustproof and waterproof effects can be achieved.

Referring to fig. 1, the pin inserting device further includes a pin inserting assembly 6, wherein the pin inserting assembly 6 is composed of a plurality of L-shaped pins 61; the pin assembly 6 is integrally injection molded on the base 1.

Specifically, the part of the L-shaped pin 61 in the horizontal direction is injection molded in the base 1, and the part of the pin 61 in the vertical direction passes through the circuit board 5 and is soldered and fixed with the circuit board 5, thereby playing a role in signal transmission.

The operating principle of the automobile central lock switch is as follows:

when the switch is in an initial state, the light touch switch 51 on the circuit board 5 and the ejector rod 4 are pre-pressed by 0.1mm, so that the switch cannot have an idle stroke in the initial state and cannot shake up and down. The ejector rod 4 is positioned between the locking button 31 or the unlocking button 32 and the tact switch 51, and when a downward operating force is applied to the locking button 31 or the unlocking button 32, the ejector rod 4 can be driven to move downwards along the limiting hole 22 of the shell 2 and transmit the acting force to the tact switch 51, so that the tact switch 51 is conducted, and locking or unlocking is realized; when the operating force is removed, the tact switch 51 has an automatic rebounding function, and the rebounding force is applied to the jack 4 to move the jack 4 upward, so that the lock button 31 or the unlock button 32 is reset, and the tact switch 51 is turned off.

The technical means disclosed by the scheme of the present invention is not limited to the technical means disclosed by the above embodiments, but also includes the technical scheme formed by the arbitrary combination of the above technical features. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also considered as the protection scope of the present invention.
