Technical Field
The utility model relates to an automotive electrical apparatus technical field especially relates to a switch module and car.
Background
Self-locking micro switches are required to be arranged at a plurality of positions on the automobile. The self-locking microswitch is internally provided with a self-locking component for applying self-locking force to the internal contact, and the internal contact can be kept at a closed position under the action of the self-locking force.
In detail, when the driving part of the self-locking microswitch is pressed, the pressing force is transmitted to the internal contact through the internal transmission structure of the self-locking microswitch, so that the internal contact is closed, and the switch conduction is realized. After the driving part is released, the driving part is reset, but the internal contact can still be kept at the closed position due to the self-locking force, so that the normally-on switch is realized. And the driving part of the self-locking microswitch is pressed again, and the pressing force overcomes the self-locking force to disconnect the internal contact, so that the disconnection of the switch is realized.

Drawings
Fig. 1 is a schematic diagram of a switch assembly according to an embodiment of the present invention.
The reference numerals are explained below:
the light-gathering lamp comprises a shell 1, a self-locking microswitch 2, a driving part 21, a key 3, a pressing part 31, a butting part 32, an elastic part 4, an indicator lamp 5, a luminous body 51 and a light-gathering barrel 52.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following provides a detailed description of the technical solution of the present invention with reference to the accompanying drawings.
It should be noted that, in the description of the present invention, the directions or positional relationships indicated by "upper", "lower", etc. are based on the directions or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but not for indicating or implying that the system or element referred to must have a specific direction, be constructed and operated in a specific direction, and thus should not be construed as limiting the present solution.
As shown, the switch assembly includes a housing 1, a self-locking microswitch 2 and a push button 3.
The self-locking microswitch 2 is arranged in the shell 1, and the key 3 can abut against the driving part 21 of the self-locking microswitch 2 when pressed, so that the driving part 21 drives the internal contact of the self-locking microswitch 2 to be disconnected or closed, and the on-off of the self-locking microswitch 2 is realized.
The push button 3 is connected to the housing 1 through the elastic member 4, and when the push button 3 is released, the push button can be returned to a position (shown in the figure) where it is not in contact with the driving portion 21 of the self-locking microswitch 2 by the elastic force of the elastic member 4.
That is, the push button 3 is pressed to abut against the driving unit 21, the push button 3 is released to be out of contact with the driving unit 21, and the push button 3 and the driving unit 21 are not always connected.
As described in the background art, the conventional self-locking microswitch for automobiles is easily disconnected when the automobile runs on a bumpy road, cannot be kept normally on stably, and is not good for the running safety of the automobile.
The analysis shows that the driving part of the self-locking microswitch is connected with the key, and the driving part is always connected with the key no matter the key is in a pressing state or a loosening state, and the volume of the key is usually set to be larger for the convenience of pressing, so that the vibration amplitude of the key is larger in the running process of an automobile, and the driving part connected with the key is driven to move, so that the driving part overcomes the self-locking force (the self-locking force of the self-locking microswitch is usually smaller) to drive the internal contact to be disconnected, and the self-locking microswitch cannot be stably kept normally on.
According to the scheme, the connection relation between the key 3 and the driving part 21 is released, the elastic piece 4 is arranged, the key 3 is separated from the driving part 21 under the action of elastic force after being loosened, and therefore when the key 3 vibrates, the driving part 21 is not affected, and the self-locking microswitch 2 can be guaranteed to be kept normally and stably.
The self-locking microswitch 2 of the switch assembly can be kept normally open stably, so that the switch assembly is very suitable for vibration occasions, such as automobiles. Of course, the vibration-free vibration generator can be used in non-vibration occasions in practical implementation.
In a specific scheme, an opening is formed in the upper part of the shell 1. The push button 3 includes a pressing portion 31 for receiving a pressing force and an abutting portion 32 for abutting against the driving portion 21, and the pressing portion 31 and the abutting portion 32 may be integrally formed. The pressing portion 31 is located above the opening of the housing 1, the upper end of the abutting portion 32 is connected to the pressing portion 31, and the lower end extends into the housing 1 to abut against the driving portion 21.
In a specific scheme, the pressing portion 31 is a plate, the abutting portion 32 is a rod, the abutting portion 32 is connected to the middle of the pressing portion 31, and the pressing portion 31 and the abutting portion form a T-shaped structure. The key 3 of this structure is easy to arrange and the elastic member 4 is easy to arrange, so that the elastic member 4 can be connected between the pressing portion 31 and the housing 1.
In a specific scheme, the elastic part 4 is a spring, the service life of the spring is long, and the design requirement of frequent pressing can be met. Of course, other types of elastic members, such as elastic pads, may be used in practice.
It is preferable to provide a plurality of elastic members 4 (only two are shown in the drawing), and arrange each elastic member 4 uniformly on the periphery of the abutting portion 32, that is, arrange each elastic member 4 at equal intervals on the circumference centering on the abutting portion 32. Thus, the elastic force applied to the pressing portion 31 can be ensured to be uniform, and the key 3 can move along the axis of the abutting portion 32 (i.e., move up and down in the drawing) after being released, so that the problem that the key 3 cannot abut against the driving portion 21 when pressed next time due to deflection does not occur.
In the concrete scheme, still set up pilot lamp 5 for instruct auto-lock micro-gap switch 2 to open and close the state, it is detailed, pilot lamp 5 includes the luminous body 51 of being connected with auto-lock micro-gap switch 2 electricity, still includes a spotlight section of thick bamboo 52, and luminous body 51 installs in shell 1, is equipped with the mounting hole on pressing the portion 31, and a spotlight section of thick bamboo 52 is installed in this mounting hole, and just to luminous body 51 under the mounted state, thereby can show the light that luminous body 51 sent outside shell 1. Specifically, when auto-lock micro-gap switch 2 switches on, pilot lamp 5 lights, and when auto-lock micro-gap switch 2 breaks off, pilot lamp 5 does not light.
It is right above the utility model provides a switch module and car have carried out detailed introduction. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the method and its core ideas of the present invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
