Description
Technical Field
The present invention relates to a push switch device, and more particularly, to a push switch device capable of controlling a rebound sound.
Background
At present, for example, in-vehicle electronic devices installed in a vehicle, by pressing keys provided on the surface of the electronic device, the electronic device can be controlled and operated to implement corresponding functions. In addition, in order to provide a good tactile response when a user presses a key and to allow the key to automatically return after pressing, an elastic structure having a buckling deformation characteristic is generally provided between the key and an electronic substrate on which a switch is provided. For example, the button may be made of rubber with elastic properties or made of a spring, and when the button is pressed, the button moves towards the electronic substrate and the elastic structure is driven to elastically deform, such that the elastic structure is bent or compressed, and an elastic force is generated, wherein the elastic force gradually becomes stronger according to the gradual deformation of the elastic structure, and a pressing tactile force is fed back to the user. On the other hand, after the user finishes pressing, the elastic force generated by the elastic structure can restore the user to the original position, and meanwhile, the user drives the key to restore to the original position along with the restoration of the elastic structure.
As shown in fig. 1, the front surface of the pressing portion 100 is pressed to the right side, the connecting portion 200 provided on the rear surface of the pressing portion 100 moves along the support portion 300 toward the electronic substrate 500, the elastic structure (not shown) comes into contact with the electronic substrate 500 and the connecting portion 200, and the elastic structure is elastically deformed as the connecting portion 200 moves toward the electronic substrate 500. The elastic structure restores the original position under the elastic force, and simultaneously, drives the connection part 200 to move to the original position to the left side. In order to prevent the coupling portion 200 from moving excessively, to ensure that the pressing portion 100 can be reset, and to ensure the appearance of the key, a claw portion 400 is provided at an end portion of the coupling portion 200. As shown in the drawing, when the connection portion 200 moves from the electronic substrate 500 to the pressing portion 100, the claw portion 400 abuts against the end of the support portion 300, and the movement of the connection portion 200 to the left side is restricted.
However, the claw portion 400 and the support portion 300 are in surface-to-surface contact, and the claw portion 400 and the support portion 300 are in surface-contact at a constant speed by the elastic force of the elastic structure, and a collision sound is generated between the two member materials. When the interior of the automobile is quite quiet, the texture of the product is obviously affected, and a user feels that the product is manufactured roughly.
In addition, a lot of burrs are generated at the end of the support part 300 during molding, and the contact surface of the claw part 400 may contact the burrs when approaching the support part 300, thereby generating noise, affecting the sound environment in the vehicle, and reducing the quality of the product.
In addition, since there is a space between the connection part 200 and the support part 300 during the rebound of the key, when the rebound force is too large, the claw part 400 may be separated from the support part 300, which may cause the disengagement of the key and the defective product.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a push switch device capable of suppressing a click-back sound.
The push switch device of the present invention comprises: a pressing part; a connecting part arranged on the back of the pressing part; a support portion for supporting the connection portion and enabling the connection portion to slide forward and backward; a claw portion provided at an end portion of the connecting portion; and a protrusion provided on the support portion and having a restriction surface abutting against the claw portion and an inclined surface, wherein when the connection portion is inserted into the support portion, the claw portion comes into contact with the inclined surface, and the connection portion is elastically deformed.
According to the push type switch device, the rebound sound generated when the switch key rebounds can be reduced, the texture of a product is improved, and the influence of the sound on the environment is eliminated. In addition, when the connecting part is inserted into the supporting part, the claw part is contacted with the inclined surface to generate elastic deformation and generate elastic force, so that when the connecting part rebounds, the connecting part is kept to be close to the supporting part, the claw part is ensured to be contacted with the protruding part, the connecting part and the claw part are prevented from being separated from the supporting part, and the occurrence of the problem of key separation is avoided.

Detailed Description
Preferred embodiments of the push switch device according to the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a perspective sectional view of the push switch device of the present embodiment, fig. 3 is a side view of the push switch device of the present embodiment, and fig. 4 and 5 are partial views of the push switch device of the present embodiment. The push-type switch device of the present embodiment is a switch button horizontally mounted on a vehicle-mounted instrument. As shown in fig. 2, the push switch device includes: pressing part 1, connecting part 2, supporting part 3, claw part 4, protruding part 5, and electronic substrate 6.
In the present embodiment, the pressing portion 1 has a plate-like structure having a quadrangular surface when viewed from the front. Characters or symbols (not shown) are engraved on the surface of the pressing portion 1, and can be used to indicate the functions represented by the characters or symbols. The pressing portion 1 may be made of a resin material.
The connecting portion 2 has a columnar structure formed to extend rearward from the rear surface of the pressing portion 1, and is made of a material having elastic deformability, for example, a resin material. As shown in fig. 2 and 3, the connecting portion 2 extends on both the upper and lower sides of the back surface of the pressing portion 1. In the present embodiment, the pressing portion 1 and the connecting portion 2 are formed integrally.
Since the support portion 3 is fixed to the push switch device case, which is fixed to the in-vehicle instrument, the connection portion 2 on both the upper and lower sides is inserted into the support portion 3 on both the upper and lower sides, and then the movement range of the connection portion 2 and the pressing portion 1 in the up-down direction is limited, and the movable portion can slide forward and backward in the left-right direction.
Here, the connecting portion 2 and the supporting portion 3 of the present invention may also form a slide rail structure therebetween, which plays a role in guiding and stabilizing the connecting portion during sliding.
The claw portion 4 is provided at an end of the connecting portion 2 and has an abutting surface facing the support portion 3. As shown in fig. 4, the abutting surface of the claw portion 4 is formed to stand from the connecting portion 2 toward the surface of the support portion 3 toward the support portion 3, and is formed in a "", shape with the connecting portion 2. In the present embodiment, the claw portion 4 is formed integrally with the connecting portion 2.
The protrusion 5 is provided on the support 3 and protrudes toward the connection 2. As shown in fig. 3 and 4, the protruding portion 5 is raised from the end of the support portion 3 to the connection portion between the connection portion 2 and the claw portion 4, and the cross-sectional area decreases toward the connection portion. In the present embodiment, the protruding portion 5 is formed integrally with the support portion 3.
As shown in fig. 4, the protruding portion 5 includes a regulating surface 51 and an inclined surface 52. The restricting surface 52 is an arc surface, and the restricting surface 51 contacts the abutting surface of the claw 4 during the rebound of the connecting portion 2 to restrict the connecting portion 2 from moving further to the left in the left-right direction, and the positions of the claw 4 and the protruding portion 5 are set according to the position requirement of the pressing portion 1, so that the pressing portion 1 can rebound to the required position when the claw 4 contacts the restricting surface 51.
Here, in the present invention, the abutting surface of the claw portion 4 may be provided as an arc surface, and the regulating surface 51 may be an inclined straight surface, or both the abutting surface of the claw portion 4 and the regulating surface 51 may be provided as an arc surface.
As shown in fig. 4, the inclined surface 52 is provided between the regulating surface 51 and the support portion 3 toward the connection portion 2. A gap is formed between the inclined surface 52 and the surface of the connection portion 2, and when the connection portion 2 is inserted into the support portion 3, the claw portion 4 comes into contact with the inclined surface 52 and elastically deforms the connection portion 2.
In addition, an electronic board 6 is provided on the bottom of the housing of the push switch device in the extending direction of the connecting portion 2. The facing pressing portion 1 is made of a material having good insulation properties. A switch and a light source (not shown) are further provided on the electronic substrate 6 at a position facing the pressing portion 1.
Here, the switch is made of metal having high conductivity such as aluminum alloy, copper, and silver, and a material such as graphite and conductive polymer may be used. The light source may be an LED, a stripe-shaped organic EL, an inorganic EL, or the like.
In the present embodiment, an elastic structure (not shown) is further provided between the connection portion 2 and the electronic substrate 6. For example, a rubber structure or a spring structure, one end of which is connected to the connecting portion 2 and the other end of which is connected to the electronic board 6, and a contact point is provided at a position corresponding to a switch fixed to the electronic board 6 on the side of the elastic structure facing the electronic board 6. The contact may be made of a metal having high conductivity such as aluminum alloy, copper, or silver by printing or coating, or may be made of a material such as graphite or a conductive polymer. When the user presses the pressing part 1, the connecting part 2 presses the elastic structure to move towards the electronic substrate 6, and the contact contacts with the switch on the electronic substrate 6 at the corresponding position, an electronic circuit (path) is formed, and corresponding control can be performed, for example: on/off control of the vehicle lamp.
Thus, when the user presses the pressing portion 1, the elastic structure is restored to the original position by the elastic force generated by the elastic deformation after the finger is released, and the connecting portion 2 is pushed to move toward the pressing portion 1. As shown in fig. 3, the connection portion 2 moves to the left side from the electronic substrate 6. As shown in fig. 4 and 5, when the abutting surface of the claw portion 4 comes into contact with the regulating surface 51 of the protruding portion 5, the connecting portion 2 stops moving, and at the same time, the pressing portion 1 also stops moving. At this time, as shown in the drawing, the abutting surface of the claw portion 4 and the regulating surface 51 of the protruding portion 5 are in contact with each other by a curved surface, that is, in line contact, and the contact area is small, so that the generated rebound contact noise is small.
When the connection portion 2 is inserted into the support portion 3, the claw portion 4 of the connection portion 2 comes into contact with the inclined surface 52 of the projection portion 5, and the connection portion 2 is elastically deformed to generate an elastic force, and if the connection portion 2 is removed, the claw portion 4 needs to be disengaged from the projection portion 5 against the elastic force of the connection portion 2. Therefore, the claw portions 4 cannot be disengaged from the protruding portions 5 during the rebound of the connecting portion 2, and the connecting portion 2 is ensured not to be disengaged.
Here, the gap between the connecting portion 2 and the supporting portion 3, the protruding length of the protruding portion 5, the standing height of the claw portion 4, and the like may be set according to design requirements.
Fig. 6 and 7 are schematic views of another embodiment of the push type switch device of the present invention. As shown in the drawing, a projection 41 is provided on the abutting surface of the claw portion 4.
The protrusion 41 is formed to protrude from the abutting surface of the claw portion 4 toward the restriction surface 51. In the present embodiment, the projection 41 has an arc shape and is formed integrally with the claw portion 4. When the claw portion 4 approaches the regulating surface 51, the projection 41 first comes into contact with the regulating surface 51, and thus the arc surface of the regulating surface 51 comes into contact with the arc surface of the projection 41, which can be regarded as point contact, and the contact area thereof is smaller than that of line contact, so that the rebound contact noise can be further reduced.
Here, the projection may be provided on the restriction surface toward the abutting surface of the claw portion, and the number of projections is not limited, and a plurality of projections may be provided according to design requirements, thereby achieving an effect of more stabilizing at the time of the resilient contact.
Further, since some burrs are generated on the surfaces of the protruding portion 5 and the claw portion 4 during production, when the abutting surface of the claw portion 4 approaches the restricting surface 51 of the protruding portion 5, the protrusion 41 comes into contact with the restricting surface 51 first, and thus, the abutting surface of the claw portion 4 or the restricting surface 51 of the protruding portion 5 is prevented from coming into contact with the burrs, and generation of abnormal noise is prevented.
Further, as shown in fig. 7, the inclined surface 52 of the protrusion 5 is inclined at the same angle as the inclined surface of the upper end surface of the claw portion 4, so that the claw portion 4 can easily pass through the protrusion 5 when the connection portion 2 is inserted into the support portion 3, and the mounting can be performed more smoothly.
The push type switch device of the present invention is not limited to use in vehicle-mounted instruments, and is also applicable to all electronic devices.
