Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a toggle switch used for a car seat. Background Art

[0002] With the development of the automobile industry, improving the comfort and convenience of the vehicle interior has become an important design direction. Among the many in-vehicle components, the reliability and user experience of the seat adjustment device are particularly critical. At present, the common seat toggle switches on the market mostly use an upright toggle rod as the opening and closing part. Although this design has a simple structure, it has many shortcomings in actual use. First, the upright toggle rod is prone to breakage due to frequent operation, affecting the normal use of the seat adjustment function. Secondly, most seat switches use reeds for reset. After long-term use, the reeds are prone to fatigue, resulting in inaccurate reset or failure, which in turn affects the user's operating experience.

[0003] In view of the above problems, improved solutions have been proposed in the prior art. For example, Chinese utility model patent CN217444273U discloses an easy-to-flip seat switch, which eliminates the traditional toggle lever and reed and uses a push handle and an upright spring to achieve the reset function. However, this solution still has certain defects. The upright spring is prone to permanent deformation after being compressed for a long time, resulting in weakened reset force and slow reset, and affecting the service life and stability of the switch. In addition, the upright spring has high requirements for position accuracy during installation, which increases production costs and assembly difficulties. Summary of the invention

[0004] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a toggle switch for a car seat, which solves the problems of structural instability, easy damage and poor user experience of traditional car seat toggle switches.

[0005] The technical solution of the utility model comprises a toggle cover, a base, a static contact piece, a moving contact piece and a fulcrum protrusion, the toggle cover covers the top of the base and is movably arranged on the base, the static contact piece is fixedly installed on the base, the moving contact piece contacts the fulcrum protrusion and tilts and swings around the fulcrum protrusion; a return spring is installed on the inner side of the toggle cover, the return spring is arranged along the toggle direction and the two ends of the return spring respectively press against the toggle cover in the initial state of the toggle cover, the two sides of the base are respectively provided with pressure platforms, the pressure platforms are located on the axial sides of the return spring, and when the toggle cover is in the toggle state, one end of the return spring presses against the corresponding pressure platform.

[0006] Compared with the traditional upright spring, a technical solution such as a reset spring arranged along the toggle direction is adopted. In the initial state, the two ends of the reset spring respectively press against the toggle cover. When the toggle cover is operated, one end of the reset spring will contact the pressure platform on the base, and automatic reset is achieved by the elastic force of the spring. In this way, by optimizing the layout and working mode of the reset spring, the permanent deformation caused by long-term use is reduced, and the problems caused by long-term pressure of the traditional upright spring are avoided, thereby ensuring the long-term stability and reliability of the switch, improving the user's feel, and making the operation smoother and easier. At the same time, the elastic force of the reset spring mainly acts in the toggle direction, and can quickly return to its original position at the moment the user releases the toggle cover, thereby enhancing the user's experience. In addition, the installation position and direction of the reset spring help to reduce the requirements for position accuracy, simplify the assembly process, and thus reduce production costs.

[0007] In a possible design, a plurality of limit plates arranged along the toggling direction are integrally provided in the toggle cover, and the return spring is installed between the limit plates. The end of the limit plate has an inner support platform, and the two ends of the return spring are abutted against the inner support platform, and a channel for the pressure platform to enter is formed between the inner support platforms of adjacent limit plates.

[0008] With the above design, the limit plate and the inner support platform play the role of positioning the reset spring, ensuring that both ends of the reset spring always maintain stable contact with the toggle cover, avoiding possible position offset or distortion during the reset process, thereby improving the accuracy of the reset; at the same time, the channel provides space for the pressure platform to enter, so that the pressure platform can fully contact the elastic force of the spring, ensuring the rapidity of the reset.

[0009] In one possible design, a reed is installed in the toggle cover, and the cross-section of the reed is in the shape of a "J", including a U-shaped protrusion and supporting feet on both sides of the U-shaped protrusion. The supporting feet support and top against the toggle cover, and the U-shaped protrusion contacts and elastically presses on the moving contact piece.

[0010] With the above design, the reed can be in close contact and elastically pressed against the moving contact piece, driving the moving contact piece to swing and being tightly connected with the static contact piece, reducing the occurrence of poor contact; at the same time, the "J"-shaped shape of the reed piece allows it to maintain good elasticity and stability during long-term use, reducing the risk of failure due to fatigue, improving its anti-fatigue performance, and thus enhancing the structural stability of the entire switch.

[0011] In a possible design, a plurality of upright protrusions are integrally provided on the top surface of the toggle cover.

[0012] By adopting the above design, multiple bosses are used to replace the toggle rods or push handles in the prior art, thereby enhancing the structural strength of the entire toggle cover, making it less likely to deform or damage under frequent operation. The bosses and the toggle cover are integrally formed, reducing the number of parts, reducing additional assembly steps, and simplifying the production process.

[0013] In a possible design, the movable contact piece is provided with a fulcrum groove, and the fulcrum groove is in contact with and cooperates with the fulcrum protrusion.

[0014] The above design enables the movable contact piece to be accurately positioned when it swings around the fulcrum protrusion, ensuring that each tilting and swinging is accurately in place, reducing the shaking and loosening of the movable contact piece during the swinging process, and ensuring the stable movement of the movable contact piece.

[0015] In a possible design, a frame plate is integrally provided on the toggle cover in the thickness direction, a track hole is opened in the frame plate, an oblique clamping block is protruded from the side of the base, the oblique clamping block is placed in the track hole and slidably cooperates with the track hole.

[0016] The above design ensures that the toggle cover can move smoothly along a predetermined track during operation, thereby improving the accuracy of the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figures 1-5A toggle switch for an automotive seat as shown includes a toggle cover 1, a base 2, a static contact piece 3, a moving contact piece 4, and a fulcrum projection 5. The toggle cover 1 covers the upper part of the base 2 and is movably arranged on the base 2. The movement of the toggle cover 1 drives the internal components to act, realizing the function of switching the circuit. The static contact piece 3 is fixedly installed on the base 2. The moving contact piece 4 contacts the fulcrum projection 5 and tilts and swings around the fulcrum projection 5. The on-off of the static contact piece 3 and the moving contact piece 4 means the switching of the circuit. A return spring 6 is installed inside the toggle cover 1. The return spring 6 is arranged along the toggling direction, and both ends of the return spring 6 respectively abut against the toggle cover 1 in the initial state of the toggle cover 1. There are respectively pressure-receiving platforms 21 on both sides inside the base 2. The pressure-receiving platforms 21 are located on both axial sides of the return spring 6, and in the toggled state of the toggle cover 1, one end of the return spring 6 abuts against the corresponding pressure-receiving platform 21. Both ends of the return spring 6 abut against the toggle cover 1 in the initial state, ensuring that the toggle cover 1 remains in the original position without external force. When the toggle cover 1 is operated, for example, the return spring 6 is forced to displace to the left, the left end of the return spring 6 will contact and abut against the left pressure-receiving platform 21 on the base 2, and the right end of the return spring 6 still abuts against the toggle cover 1. The return spring 6 is in a compressed state under force. After releasing the toggle cover 1, the toggle cover 1 returns to the initial position due to the elastic force of the return spring 6 until the return spring 6 returns to the initial state. In the above process, the elastic force of the return spring 6 directly acts in the toggling direction, improving the return efficiency and ensuring the long-term stability and reliability of the switch.

[0024] Two limiting plates 11 arranged along the toggling direction are integrally provided inside the toggle cover 1. The return spring 6 is installed between the two limiting plates 11. The two end parts of the limiting plates 11 on both sides in the toggling direction have inner supporting platforms 12. The inner supporting platforms 12 protrude inwards. Both ends of the return spring 6 are in abutting cooperation with the inner supporting platforms 12. A channel 13 for the pressure-receiving platform 21 to enter is formed between the inner supporting platforms 12 of the adjacent limiting plates 11. During the toggling operation, due to the displacement of the toggle cover 1, the pressure-receiving platform 21 penetrates into the channel 13 and abuts against one end of the return spring 6, thereby compressing the return spring 6. After releasing the toggle cover 1, the pressure-receiving platform 21 withdraws from the channel 13 due to the elastic force of the return spring 6.

[0025] A reed 7 is installed inside the toggle cover 1. The cross-section of the reed 7 is in a "ji" shape, including a U-shaped projection 71 and supporting feet 72 on both sides of the U-shaped projection 71. The supporting feet 72 are inclined and the ends thereof support and abut against the inside of the toggle cover 1. The U-shaped projection 71 contacts and elastically presses against the moving contact piece 4. In the initial state, the U-shaped projection 71 elastically contacts the top surface position of the moving contact piece 4, and this position is close to the fulcrum projection 5 or opposite to the fulcrum projection 5. When the toggle cover 1 is forced to displace, the reed 7 moves along with it. The contact position between the U-shaped projection 71 and the moving contact piece 4 shifts towards one end of the moving contact piece 4, causing the moving contact piece 4 to swing to one side, and the moving contact piece 4 contacts and connects with the corresponding static contact piece 3 to switch the circuit.

[0026] Six upright convex posts 14 are integrally provided on the top surface of the toggle cover 1. The six convex posts 14 are evenly arranged according to a predetermined rule, and the convex posts 14 are connected to the corresponding mechanism on the seat, enabling the force applied by the user to be transmitted to the toggle cover 1. Compared with the toggle rod or push handle of the prior art, the multiple low convex posts 14 are integrally formed with the toggle cover 1 and are not easily damaged, and the assembly is convenient.

[0027] The moving contact piece 4 is provided with a fulcrum groove 41, and the fulcrum groove 41 is in contact and cooperation with the fulcrum projection 5. When the moving contact piece 4 is stressed, it swings around the contact position between the fulcrum groove 41 and the fulcrum projection 5, and then one end of the moving contact piece 4 is in contact connection with the static contact piece 3. The moving contact piece 4 is integrally in the shape of a section of an arc and is made of a hard metal.

[0028] A frame plate 15 is integrally provided in the thickness direction of the toggle cover 1. A track hole 16 is provided in the frame plate 15, and the track hole 16 is arranged along the toggling direction. An inclined clamping block 22 protrudes from the side surface of the base 2, and the inclined clamping block 22 is placed in the track hole 16 and is in sliding fit with the track hole 16. The inclined clamping block 22 can be stuck in the track hole 16 to prevent the toggle cover 1 from moving in the thickness direction, but can be displaced along the predetermined track of the track hole 16 to realize the toggling translation action of the toggle cover 1.
