Description

Technical Field

[0001] The present invention relates to the field of automotive electronics technology, and more specifically, to a dual-axis toggle switch structure. Background Art

[0002] With the increasingly fierce competition in the automotive industry, it is required that the toggle switch can more simply achieve basic functions, be more stable, have a longer service life, and be more cost-effective. Therefore, it is urgent to apply a new structure in the industry.

[0003] The existing traditional two-way toggle switch adopts a single-axis structure. This design method has a complex pressing block structure and is prone to offset during operation. Due to the point contact between the pressing block and the lever structure, large wear occurs, affecting the switch life. When toggling the switch, the single-axis toggle switch has more force arm transmission chains, resulting in large force transmission loss and low efficiency during the movement process, and requires a greater operating force. In addition, the single-axis structure is not stable enough. Summary of the Invention

[0004] The present invention overcomes the deficiencies of the prior art. Its structure is reasonably designed, greatly simplifies the pressing block structure and its movement form, has a lower design cost, improves the force transmission efficiency of the transmission block and the lever structure, reduces the operating force, improves the feel, increases the structural stability with a dual-axis design, and reduces wear with line contact, thereby improving the switch life.

[0005] To achieve the above object, the present invention provides the following technical solutions: A dual-axis toggle switch structure includes a housing, a lever, a transmission block, a pressing block, a conductive rubber, and a circuit board. The lever is fixedly or integrally provided with the transmission block. The transmission block is installed in the housing and can move up and down relative to the housing. The lever is connected above the transmission block and can swing relative to the housing. There are two pressing blocks and two conductive rubbers respectively. Both conductive rubbers can deformably move to abut against or away from the circuit board. The two pressing blocks are movably installed in the housing in the vertical direction. Both ends of the two pressing blocks respectively abut against the conductive rubber and the transmission block. The transmission block includes two abutting shafts arranged horizontally and abutting against the pressing block, a support section arranged vertically and connecting the two abutting shafts and used for connecting with the lever, and a connecting section arranged vertically and connecting the two abutting shafts. The two abutting shafts, the support section, and the connecting section are integrally formed. A support portion extends outward along the side of the front end of the support section. The lever is connected to the support portion. A swing block extends outward from the side of the support portion. A swing groove is provided on the housing corresponding to the swing block. The swing block is located in the swing groove and can swing relative to the swing groove.

[0006] Preferably, the swing groove is opened on the outer periphery of the housing. An articulated groove block opposite to the swing groove is provided at the inner position of the housing. An opening is provided in the middle of the transmission block and between the two abutting shafts. An articulated block is provided on the side of the support section facing the opening. The articulated block is swingably installed in the articulated groove block.

[0007] Preferably, the bottom of the abutment shaft is configured as an abutment portion, which is substantially H-shaped, and the abutment portion is configured as a connecting abutment portion abutting against the pressure block in the middle of the H-shape, and the connecting abutment portion is a flat surface.

[0008] Preferably, the pressing block includes a straight abutting block abutting against the connecting abutting portion, a sliding block arranged orthogonally to the straight abutting block and lower than the straight abutting block, and a bottom contact block arranged at the bottom and abutting against the conductive rubber.

[0009] Preferably, a cross groove is provided inside the shell at a position corresponding to the pressing block, and both the straight abutting block and the sliding block can be slidably disposed in the cross groove.

[0010] Preferably, the transmission block is provided with guide blocks on the outer sides of the edges of the supporting section and the connecting section, and the positions of the shell corresponding to the guide blocks are provided with sliding grooves and / or sliding holes cooperating with the guide blocks.

[0011] Preferably, a positioning groove for accommodating the guide rubber is provided in the shell below the cross groove, a positioning column is extended downward from the bottom of the shell, and the circuit board is arranged at the bottom of the shell and fixedly connected to the shell through the positioning column.

[0012] Beneficial effects of the present invention: 1. The force arm transmission chain is reduced, the force transmission efficiency is increased, the operating force required for dialing is reduced, and the hand feel is better; 2. The two abutting shafts (i.e. the double shafts mentioned below) share the load together, which can withstand greater pulling force, and the structure is more stable, reducing the possible displacement of the pressure block in the single-shaft structure and increasing reliability; 3. The dual-axis structure can better maintain the balance of the lever structure and reduce the size chain, making the accuracy higher, reducing the jam when shifting, and providing a better user experience; 4. The dual-axis structure greatly simplifies the pressure block structure. The downward force is directly transmitted from the lever structure to the pressure block and the conductive rubber at the same time without the rotation of the pressure block, which reduces the force transmission loss. 5. Line contact is used instead of point contact between the lever structure and the pressure block to reduce stress concentration and surface wear and increase the life of the switch.

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] Such as Figure 1-9As shown, a biaxial toggle switch structure includes a housing 1, a toggle lever 2, a transmission block 3, a pressure block 4, a conductive rubber 5, and a circuit board 6. The toggle lever 2 is fixedly or integrally provided with the transmission block 3. The transmission block 3 is installed in the housing 1 and can move up and down relative to the housing 1. The toggle lever 2 is connected above the transmission block 3 and can swing relative to the housing 1. There are two pressure blocks 4 and two conductive rubbers 5 respectively. Both of the two conductive rubbers 5 can deformably move to abut against or away from the circuit board 6. The two pressure blocks 4 are movably installed in the housing 1 in the vertical direction. Both ends of the two pressure blocks 4 respectively abut against the conductive rubber 5 and the transmission block 3. The transmission block 3 includes two abutting shafts 31 arranged horizontally and abutting against the pressure block 4, a support section 32 arranged vertically and connecting the two abutting shafts 31 and used for connecting with the toggle lever 2, and a connecting section 33 arranged vertically and connecting the two abutting shafts 31. The two abutting shafts 31, the support section 32, and the connecting section 33 are integrally formed. A support portion 321 extends outward along the side of the front end of the support section 32. The toggle lever 2 is connected to the support portion 321. A swing block 322 extends outward from the side of the support portion 321. A swing groove 11 is provided on the housing 1 corresponding to the swing block 322. The swing block 322 is located in the swing groove 11 and can swing relative to the swing groove 11. The swing groove 11 is opened on the outer periphery of the housing 1. An articulated groove block 12 opposite to the swing groove 11 is provided at the inner position of the housing 1. An opening 34 is provided in the middle of the transmission block 3 and between the two abutting shafts 31. An articulated block 323 is provided on the side of the support section 32 facing the opening 34. The articulated block 323 is swingably installed in the articulated groove block 12. The bottom of the abutting shaft 31 is configured as an abutting portion 311. The abutting portion 311 is substantially in the shape of an H. The middle position of the abutting portion 311 in the shape of an H is configured as a connecting abutting portion 312 for abutting against the pressure block 4. The connecting abutting portion 312 is a flat surface. The pressure block 4 includes a flat abutting block 41 abutting against the connecting abutting portion 312, a sliding block 42 arranged orthogonally to the flat abutting block 41 and lower than the flat abutting block 41, and a bottom contact block 43 provided at the bottom and abutting against the conductive rubber 5. A cross groove 13 is provided inside the housing 1 corresponding to the pressure block 4. The flat abutting block 41 and the sliding block 42 are both slidably arranged in the cross groove 13. Guide blocks 35 are provided on the outer sides of the edges of the support section 32 and the connecting section 33 of the transmission block 3. A sliding groove 14 and / or a sliding hole 15 cooperating with the guide block 35 are provided on the housing 1 corresponding to the guide block 35. A positioning groove 16 for accommodating the guide rubber is provided below the cross groove 13 inside the housing 1. A positioning post 17 extends downward from the bottom of the housing 1. The circuit board 6 is provided at the bottom of the housing 1 and is fixedly connected to the housing 1 through the positioning post 17.

[0017] By adopting the above technical solution, in the present invention, by toggling the lever 2 to one side, since the lever 2 and the transmission block 3 are integrally formed, the swing block 322 will swing in the swing groove 11, and the hinge block 323 will swing in the hinge groove block 12, thereby causing the transmission block 3 to swing to one side. And due to the cooperative setting of the guide block 35, the sliding groove 14 and the sliding hole 15, the transmission block 3 is guided to move downward. As the transmission block 3 moves downward, the connecting abutting portion 312 will press the flat abutting block 41 to move downward, thereby deforming the conductive rubber 5, and the contact piece in the conductive rubber 5 will contact the circuit board 6.

[0018] Among them, since the lever 2 directly drives the transmission block 3 and the pressing block 4 to move downward when swinging, and the transmission block 3 has two abutting shafts 31, so that when the lever 2 swings to both sides, the corresponding side abutting shafts 31 and the pressing block 4 can be moved. By changing the structure of the transmission block 3 to form two abutting shaft 31 structures, the transmission efficiency of the operating force is increased, the structural stability is improved, and the service life of the switch is prolonged.

[0019] Moreover, by setting the connecting abutting portion 312 as a flat surface and providing a flat abutting block 41, when the transmission block 3 moves downward, the two flat surfaces can accurately and quickly conduct the downward force, which has the effect of making the switch response more sensitive. And by providing the cross groove 13 and the sliding block 42, both the flat abutting block 41 and the sliding block 42 can slide in the cross groove 13, making the movement of the pressing block 4 more accurate and further improving the transmission stability.

[0020] Furthermore, the cooperative setting of the swing groove 11, the hinge groove block 12, the swing block 322 and the hinge block 323 improves the stability of the swinging operation of the lever 2 and can achieve good movement accuracy of the transmission block 3. And setting the abutting portion 311 to be roughly H-shaped and the connecting abutting portion 312 being located in the middle of the abutting portion 311 is also to achieve the structural strength of the connecting abutting portion 312 and ensure the overall abutting strength of the connecting section 33.

[0021] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
