Description

Technical Field

[0001] This utility model belongs to the field of electrical switches, specifically relating to a self-resetting toggle switch. Background Technology

[0002] Toggle switches are frequently used in various types of vehicles, including electric vehicles and motorcycles, and for ease of control, they are required to have a self-resetting function. Existing self-resetting toggle switches contain numerous disparate components such as a moving contact, contact spring, return spring, stationary contact, and contact spring. Assembling these components during toggle switch assembly leads to low assembly efficiency due to the large number of parts. Furthermore, toggle switches often suffer from unsmooth reset action, thus affecting their performance. Utility Model Content

[0003] In response, this utility model provides an automatic reset toggle switch that is easy to assemble.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This utility model provides a self-resetting toggle switch, including a housing, a slider, a micro switch, and a resilient self-resetting structure. The housing includes a base and a cover, with a mounting cavity formed between the base and the cover. The base has a positioning groove, into which the micro switch is embedded, and the cover presses against the micro switch. The micro switch is mounted in the mounting cavity with its button facing the slider. The slider is movably disposed in the mounting cavity and adapted to move between a triggered position and a normal position. When the slider is in the triggered position, it presses the button; when the slider is in the normal position, it does not press the button. The resilient self-resetting structure provides a reset force to the slider, causing the slider to always tend to move towards the normal position.

[0006] In some embodiments, the elastic self-resetting structure includes a raceway on the housing, a spring mounted on the slider, and an abutment. The slider has a mounting groove for accommodating the spring and the abutment. The raceway has a positioning groove away from the button and an inclined guide surface near the button. The inclined guide surface is inclined. When the slider is in its normal position, the abutment abuts against the positioning groove under the elastic force of the spring. As the external force pushes the slider toward the trigger position, the abutment moves along the inclined guide surface and gradually compresses the spring.

[0007] In some embodiments, the housing is provided with an outlet, and the slider is provided with a drive rod extending from the outlet.

[0008] In some embodiments, the elastic self-resetting structure is disposed between the base and the slider.

[0009] In some embodiments, the slider has a cavity extending toward the micro switch, and a trigger portion opposite to the button is provided in the cavity. When the slider moves to the trigger position, the micro switch extends into the cavity, and the trigger portion presses the button.

[0010] In some embodiments, the cover is snapped onto the base.

[0011] In some embodiments, the base is provided with a locking block and a positioning protrusion, and the cover is provided with a locking hole corresponding to the position of the locking block and a positioning notch corresponding to the position of the positioning protrusion. When the cover is placed on the base, the locking block engages with the locking hole, and the positioning protrusion engages with the positioning notch.

[0012] In some embodiments, the housing is provided with a slot, and the wiring pins of the micro switch extend out of the housing through the slot.

[0013] In some embodiments, the slot is formed at the mating point between the base and the cover, and a micro switch closes the slot from the inside.

[0014] In some embodiments, the micro switch is a waterproof micro switch.

[0015] The advantages of this invention are as follows: The toggle switch structure is optimized by employing an elastic self-resetting structure. When the external force applied to the slider is removed, the slider returns to its initial position under the elastic force of the self-resetting structure. Furthermore, the microswitch is readily available on the market and can control the circuit's on / off state by pressing its button. This reduces the need for separate components such as moving contacts, stationary contacts, and contact springs within the housing, thus improving assembly efficiency. Additionally, to ensure stable installation of the microswitch, a positioning groove is provided on the base, allowing the microswitch to be embedded within it, and the housing effectively presses against the microswitch. This design not only ensures the stability of the microswitch but also helps to accelerate the assembly process, significantly improving overall assembly efficiency. Attached Figure Description

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0025] The self-resetting toggle switch structure in this embodiment of the utility model is as follows: Figures 1 to 5 As shown, it includes a housing 1, a slider 2, a micro switch 3, and a resilient self-resetting structure. For ease of assembly, the housing 1 is designed as a modular assembly structure. Specifically, the housing 1 includes a base 13 and a cover 14. Preferably, the cover 14 is snapped onto the base 13, and the tight connection between the base 13 and the cover 14 forms a complete housing 1. The micro switch 3 can be purchased directly from the market and can control the circuit's on / off state by pressing its button 31. This reduces the need for separate components such as moving contacts, stationary contacts, and contact springs inside the housing 1, improving assembly efficiency. The micro switch 3 is preferably a waterproof micro switch to enhance waterproof performance. A mounting cavity is formed between the base 13 and the cover 14 to provide suitable mounting space and support for the micro switch 3, slider 2, and resilient self-resetting structure. Figure 3 and Figure 4As shown, a positioning groove 15 is provided on the base 13, the micro switch 3 is embedded in the positioning groove 15, and the cover 14 presses against the micro switch 3, thereby ensuring the stability of the micro switch 3 installation and quick assembly, which helps to improve assembly efficiency.

[0026] like Figure 3 As shown, the micro switch 3 is installed in the mounting cavity with its button 31 facing the slider 2. The slider 2 is movably disposed in the mounting cavity and is adapted to move between a triggered position and a normal position. When the slider 2 is in the triggered position, it presses the button 31; when the slider 2 is in the normal position, it does not press the button 31. Thus, the switch body 3 has different switching states when the slider 2 is in the triggered position and the normal position. The elastic self-resetting structure provides a reset force to the slider 2, so that the slider 2 always maintains the tendency to move towards the normal position. The self-resetting toggle switch structure in this embodiment is reasonably designed. The elastic self-resetting structure provides a continuous reset force to the slider 2, ensuring that the slider 2 always has the tendency to move towards the normal position. This design ensures the self-resetting capability of the switch, so that the switch can always quickly return to the initial state after each operation, improving the convenience of use and operation.

[0027] Furthermore, such as Figures 3 to 5 As shown, the elastic self-resetting structure includes a raceway 11 on the outer shell 1, a spring 4 mounted on the slider 2, and a stop member 5. The slider 2 is provided with a mounting groove 21 for accommodating the spring 4 and the stop member 5. The raceway 11 is provided with a positioning groove 111 away from the button 31 and an inclined guide surface 112 close to the button 31. The inclined guide surface 112 is inclined. When the slider 2 is in the normal position, the stop member 5 abuts against the positioning groove 111 under the elastic force of the spring 4. During the process of the external force pushing the slider 2 towards the trigger position, the stop member 5 moves along the inclined guide surface 112 and gradually compresses the spring 4. In this way, after the external force applied to the slider 2 is removed, the spring 4 releases its elastic force and acts on the inclined guide surface 112 through the stop member 5, thereby causing the slider 2 to move towards the normal position to achieve the purpose of self-resetting. Moreover, the cooperation between the stop member 5 and the positioning groove 111 can effectively position the slider 2, ensure the stability of the slider 2 in the normal position, and improve the performance. In this embodiment, the elastic self-resetting structure is disposed between the base 13 and the slider 2, specifically the raceway 11 is disposed on the base 13; the abutment 5 can be a steel ball or a positioning pin with a hemispherical lower end, thus ensuring that the relative sliding between the abutment 5 and the inclined guide surface can be smooth.

[0028] like Figures 1 to 3As shown, the outer shell 1 is provided with an outlet 12, and the slider 2 is provided with a drive rod 22 extending from the outlet 12. With this configuration, the slider 2 can be moved by applying external force to the drive rod 22, thereby controlling the self-resetting toggle switch and improving the convenience of operation. The drive rod 22 can be injection molded as a whole with the slider 2 or fixedly connected by assembly. In actual operation, a lever can also be provided at the end of the drive rod 22 to improve the operating feel.

[0029] like Figure 1 As shown, the base 13 is provided with a locking block 131 and a positioning protrusion 132. The cover 14 is provided with a locking hole 141 corresponding to the position of the locking block 131 and a positioning notch 142 corresponding to the position of the positioning protrusion 132. When the cover 14 is placed on the base 13, the locking block 131 engages with the locking hole 141, and at the same time, the positioning protrusion 132 engages with the positioning notch 142, thereby completing the fixed connection between the base 13 and the cover 14, which is reliable.

[0030] Combination Figure 3 and Figure 5 As shown, the slider 2 has a recess 23 facing the trigger switch 3. The recess 23 has a trigger part 24 opposite to the button 31. When the slider 2 moves to the trigger position, the trigger switch 3 extends into the recess 23, and the trigger part 24 presses the button 31. The recess 23 can avoid the trigger switch 3, which increases the length of the slider 2 in its moving direction, thereby enhancing the stability of the slider 2 when installed and used in the housing 1, and also facilitating the compact design of the toggle switch.

[0031] The housing 1 is provided with a slot 10, and the wiring pin 32 of the micro switch 3 extends out of the housing 1 through the slot 10, so as to facilitate the electrical connection between the external wire and the micro switch 3 during installation and use.

[0032] More specifically, the slot 10 is formed at the mating point of the base 13 and the cover 14, so that one part of the side wall of the slot 10 is on the base 13 and the other part of the side wall is on the cover 14. During assembly, the two parts of the side wall are mated to form the slot 10. This can avoid interference between the wiring pin 32 and the edges of the base 13 and the cover 14 during the assembly process. Moreover, the slot 10 is sealed from the inside by the micro switch 3, so that the space inside the slot 10 is relatively closed. This allows for the injection of glue into the slot after the wiring pin is connected to the external wire to achieve a sealing and protective effect.

[0033] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the protection scope of this invention.
