Description

Technical Field

[0001] This utility model relates to an anti-static structure for automotive switches, belonging to the field of automotive switch technology. Background Technology

[0002] The handle of a car gear shift switch typically consists of a housing and electronic components housed within it. Existing handle housings are formed by upper and lower covers snapping together, leaving a certain gap at the joint. When static electricity is generated during vehicle use, it can enter the housing through this gap, interfering with the normal operation of the electronic components, leading to decreased switch sensitivity, and even electrical malfunction in some cases. Furthermore, static electricity can shorten the lifespan of the electronic components, increasing usage and maintenance costs.

[0003] A search revealed that patent document CN 201410921Y discloses an anti-static device, specifically an anti-static device for a car dashboard dimmer switch. Its key structural feature is that the bottom layer includes an anti-static shielding circuit distributed along the periphery of the potential circuit and connected to the external terminal of the top-layer grounding terminal on the bottom layer. The present invention provides an anti-static device for a car dashboard dimmer switch, in which an anti-static shielding circuit is distributed around the bottom potential circuit of the dimmer switch circuit board. This prevents static electricity from being generated on the operating circuit—the potential circuit—while collecting and guiding the static charge to the grounding terminal, leading it out of the switch circuit board, and eliminating the static charge on the switch circuit board. Because an anti-static shielding circuit is provided for the switch circuit board, most of the static electricity is eliminated, thus improving the overall static electricity resistance of the switch circuit. Experiments have verified that the switch's anti-static capability is improved to over 25KV, ensuring safe driving. However, this device has a complex structure, high production cost, and insufficient practicality and versatility. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an anti-static structure for automotive switches, so as to at least solve the problems mentioned in the background art.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An anti-static structure for automotive switches includes an automotive gear shift combination switch consisting of a base and a handle. The upper and lower housings of the handle are connected by a connection structure that prevents static electricity from entering the housings. The connection structure includes an elongated groove provided on the inner side of the lower housing edge along the length of the edge, and an elongated protrusion provided on the inner side of the upper housing edge that matches the elongated groove. The elongated protrusion is snapped into the elongated groove, so that the upper and lower housings are fastened together.

[0007] Furthermore, an anti-slip structure is provided on the inner side of the elongated groove and the outer side of the elongated protrusion.

[0008] Furthermore, the anti-slip structure is an anti-slip rubber pad structure set on the inner side of the elongated groove and the outer side of the elongated protrusion.

[0009] Furthermore, the anti-slip structure is an anti-slip threaded structure provided on the inner side of the elongated groove and the outer side of the elongated protrusion.

[0010] Furthermore, a protrusion is provided at the bottom of the elongated protrusion along its length, and a placement groove is provided at the bottom of the elongated groove. The protrusion is embedded in the bottom of the elongated groove through the placement groove, or the protrusion is fixed to the bottom of the elongated groove through an adhesive structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model features a simple structure and low cost. It improves the connection structure between the upper and lower housings of an automotive gear shift switch handle. An elongated groove is provided on the inner edge of the lower housing along its length, while an elongated protrusion, matching the groove, is provided on the inner edge of the upper housing. During installation, the upper and lower housings are fastened together with screws. The elongated protrusion on the edge of the upper housing engages with the elongated groove on the inner edge of the lower housing, effectively blocking the gap between the two housings. This prevents static electricity from entering the housing through the gap and interfering with the normal operation of internal electronic components when static electricity is generated on the outside of the handle, significantly improving the switch's performance and lifespan.

[0013] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] like Figures 1-5 As shown, the first embodiment of this utility model provides an anti-static structure for an automotive switch, including an automotive gear shift combination switch consisting of a base 1 and a handle 2. The internal structure of the base 1 and handle 2 remains unchanged compared to existing automotive gear shift combination switches, such as the right-hand combination switch described in patent document CN 114645937 A. The main improvement of this utility model is that the upper housing 201 and lower housing 202 of the handle 2 of the existing combination switch are connected by a connection structure that prevents static electricity from entering the housing. This connection structure includes a long strip-shaped groove 3 located on the inner edge of the lower housing 202 along its length, and a long strip-shaped protrusion 4 located on the inner edge of the upper housing 201 that matches the long strip-shaped groove 3. The long strip-shaped protrusion 4 snaps into the long strip-shaped groove 3, thus fastening the upper housing 201 and lower housing 202 together. By providing the long strip-shaped protrusion 4, the fastening gap between the upper housing 201 and lower housing 202 can be blocked. When static electricity is generated on the outside of the handle 2, it prevents static electricity from entering the housing through the gap and interfering with the normal operation of its internal electronic components.

[0023] The lower shell 202 and the elongated groove 3 are integrally molded structures. The upper shell 201 and the elongated protrusion 4 are integrally molded structures. The molding process is simple and the manufacturing cost is low.

[0024] An anti-slip structure is provided on the inner side of the elongated groove 3 and the outer side of the elongated protrusion 4. When the upper shell 201 and the lower shell 202 are fastened together, the elongated protrusion 4 is inserted into the elongated groove 3, and the anti-slip structure can make the connection between the upper shell 201 and the lower shell 202 more secure.

[0025] like Figure 4 As shown, the anti-slip structure is an anti-slip rubber pad structure 7 disposed on the inner side of the elongated groove 3 and the outer side of the elongated protrusion 4. Specifically, the anti-slip rubber pad structure 7 can be fixed to the inner side of the elongated groove 3 and the outer side of the elongated protrusion 4 by an adhesive structure. Anti-slip textures or protrusions are provided on the anti-slip rubber pad structure 7 to improve the friction of the anti-slip rubber pad structure 7.

[0026] Or, such as Figure 5 As shown, the anti-slip structure is an anti-slip threaded structure 8 provided on the inner side of the elongated groove 3 and the outer side of the elongated protrusion 4.

[0027] A protrusion 9 is provided at the bottom of the elongated protrusion 4 along its length, and the protrusion 9 and the elongated protrusion 4 are integrally formed. The protrusion 9 can be arc-shaped, square, or other structures. When static electricity is generated on the outside of the handle 2, it can better isolate the static electricity and provide dustproof and waterproof functions, greatly improving the service life of the electronic components inside the handle. Specifically, a placement groove 6 adapted to the protrusion 9 is provided at the bottom of the elongated groove 3. The protrusion 9 is fixed to the bottom of the elongated groove 3 through the placement groove 6, or the protrusion 9 is fixed to the bottom of the elongated groove 3 through an adhesive structure.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to restrict the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments without departing from the technical solution of the present utility model and based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
