Description

Technical Field

[0001] The utility model relates to the technical field of electronic switches, in particular to an electronic switch device and an electronic device. Background Art

[0002] An electronic key is a smart key system that operates via wireless signals. In the automotive industry, electronic keys are commonly used to facilitate user access to doors and trunks. An electronic key contains a small electronic chip equipped with a microswitch. When a user presses a button on the key, the button triggers the microswitch, causing the chip to transmit a radio signal, thereby operating the vehicle. Existing electronic keys often use a rocker-type button to activate the microswitch. The button is mounted on a housing and has a support shaft and two pressing shafts located on either side of the support shaft. The pressing shafts are positioned above the microswitch, and the microswitch is activated by pressing either of the pressing shafts. This rocker-type button has a complex mounting structure and manufacturing process, and its multi-shaft structure has low structural strength and is easily damaged. Furthermore, because the microswitch requires only a small amount of force to activate, accidental contact with the button can cause it to be triggered. Furthermore, excessive pressure can easily damage the microswitch, shortening the lifespan of the electronic key. Utility Model Content

[0018] Beneficial effects of the utility model:

[0019] The electronic switch device provided by the present invention has a circuit board assembly including a micro switch and a flexible buffer pad, wherein the flexible buffer pad at least covers the micro switch. The pressing assembly includes a top cover plate and an intermediate button, the top cover plate is arranged on the circuit board assembly, the top cover plate has a pressing portion, the intermediate button is arranged between the circuit board assembly and the pressing assembly, and one end abuts the pressing portion and the other end abuts the flexible buffer pad.

The intermediate button and the top cover plate are independent of each other, which simplifies the structure of the top cover plate, is easy to process and assemble, and does not destroy the structural integrity of the top cover plate. The top cover plate has good structural strength and is not easy to be damaged. Moreover, the deformation of the top cover plate is elastic and recoverable, and can be pressed repeatedly for many times, which is convenient to use. The elastic force of the top cover creates a pressing force that is transmitted through the middle button and cushioned by the flexible cushioning pad, significantly reducing the pressing force. This allows the microswitch to be triggered with a relatively gentle force while avoiding damage. This also satisfies the user's need for a strong operating feel and enhances the user experience. Even if a user accidentally touches the top cover, the smaller elastic force is buffered by the flexible cushioning pad, making it insufficient to trigger the microswitch, thus preventing accidental triggering.

[0028] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0029] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0030] like Figures 1 to 3 As shown, this embodiment first provides an electronic switch device, which includes a circuit board assembly 1 and a pressing assembly 2. The circuit board assembly 1 includes a micro switch 11 and a flexible buffer pad 12, and the flexible buffer pad 12 at least covers the micro switch 11. The pressing assembly 2 includes a top cover plate 21 and an intermediate button 22. The top cover plate 21 is covered on the circuit board assembly 1. The top cover plate 21 has a pressing portion 211. The intermediate button 22 is arranged between the circuit board assembly 1 and the pressing assembly 2, and one end abuts the pressing portion 211 and the other end abuts the flexible buffer pad 12. The top cover plate 21 can generate elastic deformation so that the pressing portion 211 drives the intermediate button 22 to move toward the direction of squeezing the flexible buffer pad 12 to trigger the micro switch 11.

[0031] The electronic switch device of this embodiment uses the user's pressing force to cause elastic deformation of the top cover plate 21. This elastic force drives the middle button 22 to actuate, thereby triggering the microswitch 11. The middle button 22 and the top cover plate 21 are independent of each other, simplifying the structure of the top cover plate 21 and facilitating processing without damaging the structural integrity of the top cover plate 21. The top cover plate 21 has good structural strength and is not easily damaged. Moreover, the deformation of the top cover plate 21 is elastic and recoverable, allowing for repeated pressing, making it easy to use. The elastic force of the top cover plate 21 generates a pressing force, which is transmitted by the middle button 22 and significantly reduced by the flexible buffer pad 12. This triggers the microswitch 11 with a relatively flexible force while avoiding damage to the microswitch 11. It also meets the user's demand for a strong operating feel and enhances the user experience. Even if the user accidentally touches the top cover plate 21, the smaller elastic force is buffered by the flexible buffer pad 12, making it insufficient to trigger the microswitch 11, greatly improving the reliability and safety of the electronic switch device.

[0032] The flexible cushioning pad 12 can be made of a rubber pad. The rubber pad covers the circuit board 13, providing protection for the entire circuit board 13 and the micro switch 11. The rubber cushioning pad 12 has excellent flexibility and cushioning properties, and is not easily deformed. By replacing the cushioning pad 12 with different thicknesses, different cushioning forces can be provided, thereby meeting the operational requirements of different users.

[0033] At least part of the top cover 21 is an arc-shaped elastic wall plate, so that the pressing portion 211 is surrounded by a hollow cavity 212, and the middle button 22 is arranged in the hollow cavity 212. The arc-shaped elastic wall plate has good elasticity, a good pressing feel, and is not easy to deform or damage.

[0034] In order to support the top cover plate 21, the pressing assembly 2 also includes a first shell 23 arranged between the top cover plate 21 and the circuit board assembly 1. The top cover plate 21 and the first shell 23 are connected by a snap-fit ​​structure, which is easy to disassemble and assemble. The specific structure of the snap-fit ​​structure can be set with reference to the existing technology, and this embodiment will not be described in detail here. The first shell 23 is provided with a support step 231, which abuts against the supporting top cover plate 21, and the support step 231 is arranged around the side of the pressing portion 211. The existence of the support step 231 further increases the volume of the hollow cavity 212 to accommodate the elastic deformation of the top cover plate 21.

[0035] The first shell 23 is provided with a guide hole 232 , and the middle button 22 can be movably inserted into the guide hole 232 . The first shell 23 provides guidance for the middle button 22 to prevent the middle button 22 from being displaced during movement and thus affecting the triggering action of the micro switch 11 .

[0036] A support portion 213 is provided on the side of the top cover plate 21 facing the first housing 23. The support portion 213 surrounds the pressing portion 211 and abuts against the support step 231. Compared to other areas of the top cover plate 21, the support portion 213 has a thicker wall, which increases the structural strength of this area and prevents deformation of the top cover plate 21 at the support step 231.

[0037] The first housing 23 has a stopper 233 on one side facing the top cover 21, protruding toward the top cover 21. A safety gap 234 is defined between the stopper 233 and the top cover 21. The stopper 233 is used to abut against and limit the deformation of the top cover 21. When the top cover 21 is subjected to a large pressure and undergoes significant elastic deformation, it abuts against the stopper 233, preventing further deformation and thus preventing damage to the top cover 21.

[0038] In one embodiment, a stopper 233 is disposed around the guide hole 232, and a safety gap 234 defines the maximum travel of the middle button 22. When the top cover 21 abuts the stopper 233, the middle button 22 reaches its maximum travel, preventing the middle button 22 from exceeding its travel range and compressing the flexible cushion 12, thereby damaging the circuit board assembly 1. This improves the safety of the electronic switch device.

[0039] A support base 221 is provided at one end of the middle button 22 that abuts the flexible cushion 12. The support base 221 abuts the flexible cushion 12, and the diameter of the support base 221 is larger than the diameter of the middle button 22. The support base 221 increases the contact area with the flexible cushion 12, reducing the pressure under the same pressing force, so that the force applied to the micro switch 11 is more relaxed.

[0040] The thickness of the pressing portion 211 is greater than the thickness of the peripheral area, which increases the structural strength of the pressing portion 211 and prevents the pressing portion 211 from being damaged when the user applies excessive force.

[0041] In one embodiment, the circuit board assembly 1 is provided with at least two micro switches 11, each corresponding to a different control operation of the electronic device. The pressing assembly 2 includes at least two intermediate buttons 22. The top cover 21 has at least two pressing portions 211, which are spaced apart and correspond one-to-one with the at least two micro switches 11. The at least two pressing portions 211 operate independently of each other to actuate the corresponding intermediate buttons 22.

[0042] For example, Figure 3 As shown, the circuit board assembly 1 is provided with two micro switches 11, the pressing assembly 2 includes two middle buttons 22, the top cover plate 21 has two pressing parts 211, and the two pressing parts 211 are arranged at intervals. The user presses different pressing parts 211, so that the area near the pressing part 211 is elastically deformed, and the pressing parts 211 act independently of each other to drive the corresponding middle button 22. Even if the pressing parts 211 in adjacent areas are slightly deformed, after being buffered by the flexible buffer pad 12, the small elastic force is not enough to trigger the corresponding micro switch 11, thereby avoiding false triggering and greatly improving the reliability and safety of the electronic switch device.

[0043] The electronic switch device also includes a bottom cover plate 3 and a decorative member 4. The bottom cover plate 3 covers the side of the circuit board assembly 1 facing away from the pressing assembly 2 and is removably connected to the pressing assembly 2. The decorative member 4 surrounds and connects to the top cover plate 21 and the bottom cover plate 3, sealing the gap between them. The shape of the decorative member 4 can be customized to suit the user's preferences, preventing impurities from entering the electronic switch device while enhancing its aesthetics.

[0044] The embodiment of the present invention secondly provides an electronic device, which includes the electronic switch device in any of the above embodiments. The electronic switch device causes the elastic deformation of the top cover plate 21 due to the pressing force of the user, drives the middle button 22 to move through the elastic force, and then triggers the micro switch 11; the structural integrity of the top cover plate 21 will not be destroyed by the middle button 22, and it is simple, has good strength, and is easy to process. The elastic force of the top cover plate 21 forms a pressing force, which is transmitted by the middle button 22 and is greatly reduced under the buffering of the flexible buffer pad 12. While triggering the micro switch 11 with a relatively flexible force, it avoids damaging the micro switch 11, and can also meet the user's demand for a large operating feel, improve the user's experience of use, and can avoid false triggering, greatly improving the reliability and safety of the electronic device.

[0045] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
