Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and in particular to a steering wheel switch assembly and a steering wheel assembly. Background Art

[0002] With the development of automobile technology, the steering wheel switch, as an important human-machine interface of the car, has a relatively powerful use function, integrating the functions including the speaker, volume increase and decrease and mode switching of the entertainment system, driving computer control, cruise control, and gear control. During driving, the driver will operate the steering wheel switch on the car to make signal prompts and driving actions. Therefore, the quality and performance of the steering wheel switch directly affect the entire driving safety and driving comfort.

[0003] An existing automobile steering wheel switch, such as Figure 1a-Figure 1c As shown, the button 50 cooperates with the universal block shaft, the universal block cooperates with the housing 60 shaft, and a pin structure is designed below the operating point, with conductive rubber 20, circuit board, etc. arranged below. The disadvantage of this structure is that when the button 50 is pressed, the button acts on the pin 10, and the pin acts on the conductive rubber 20, forcing the conductive particles 30 to move down to contact the conductive disk 40 to collect signals. The pressing function cannot be integrated into the button 50; if it is necessary to ensure full functionality (including the pressing function), a new button structure needs to be developed, the product CAS surface (modeling surface) needs to be increased, and the investment in related manpower, material resources and financial resources needs to be increased.

[0004] Another type of car steering wheel switch, such as Figure 2a-2d As shown, a four-way micro switch 70 is purchased, the switch 70 cooperates with the button hook 710, and the other end is directly welded to the circuit board. When the button 50 is turned or pressed, the button drives the micro switch to move, and the micro switch 70 directly contacts the spring inside to realize signal collection. The above two steering wheel switches cannot integrate the pressing function on the operation button 50.

[0005] Therefore, the existing automobile steering wheel switch has the problems of low functional integration and large structural size requirements. Summary of the invention

[0006] The purpose of the present invention is to solve the problems of low functional integration and large structural size requirements of the existing automobile steering wheel switch.

[0009] When the lever component deflects and swings relative to the height direction of the housing, the guide component is linked to deflect and swing, so as to drive the first coupling component to approach and abut against the circuit board;

[0010] When one end of the lever component is pressed in the axial direction of the lever component, the other end of the lever component moves along the axial direction of the lever component toward the circuit board and pushes the second coupling component to abut against the circuit board.

[0011] By adopting the above technical solution, the steering wheel switch assembly provided in this embodiment includes a lever component, a guide component, a first coupling component and a second coupling component; wherein, when the lever component swings around the axis of the lever component, the linkage guide component drives the first coupling component to approach and abut against the circuit board; when the lever component is pressed, the other end of the lever component moves along the axis of the lever component toward the circuit board, and pushes the second coupling component to abut against the circuit board. At the same time, the toggle and press functions are integrated, and its functions are more comprehensive. And the CAS surface of the product is reduced. The steering wheel switch assembly using this structure can save space for the development of the whole vehicle function, reduce the development of related necessary functional components, reduce the cost of the whole vehicle development, and shorten the whole vehicle development cycle.

[0024] When the swing rod swings around the second direction, the first universal block is linked to deflect relative to the second universal block, and the side end of the first universal block pushes the pressing block to press the first elastic conductive component;

[0025] When the swing rod swings around the first direction, the first universal block is linked to drive the second universal block to deflect relative to the housing, and the side end of the second universal block pushes the pressing block to press the first elastic conductive component;

[0026] When one end of the swing rod is pressed in the axial direction of the swing rod, the other end of the swing rod moves along the axis of the swing rod toward the circuit board and pushes the balance block to press the second elastic conductive component.

[0027] By adopting the above technical scheme, the first coupling component in this embodiment includes a pressure block and a first elastic conductive component, the second coupling component includes a balancing block and a second elastic conductive component, and a first movable space is provided between the pressure block and the first elastic conductive component, and a second movable space is provided between the balancing block and the second elastic conductive component, and the distance of the first movable space in the vertical direction is greater than the distance of the second movable space in the vertical direction; through the design of this structure, when one end of the rocker arm is pressed in the axial direction of the rocker arm, the pressure block will not press the first elastic conductive component, thereby avoiding mutual interference between the steering wheel switch assembly in this embodiment during the toggling and pressing actions.

[0028] Furthermore, another embodiment of the present invention provides a steering wheel switch assembly, wherein a hook is provided between the swing rod and the dial button, and the hook restricts the dial button from being separated from the swing rod; and

[0029] A plurality of limiting strips are arranged at the opening of the swing rod along the radial direction of the opening, and the operating portion is engaged with the plurality of limiting strips to be fixed relative to the swing rod.

Based on the arrangement of this structure, when the swing arm is deflected to a certain angle, the other end of the lever part abuts against the blocking part, and the blocking part can limit the lever part from moving downward to trigger the pressing function. Therefore, by the arrangement of this structure, the steering wheel switch assembly in the present embodiment can be further prevented from triggering the pressing function when the toggle function is realized, and the independence of the steering wheel switch assembly when toggling and pressing can be ensured, which can further improve the reliability of the steering wheel switch assembly in the present embodiment.

[0036] Furthermore, another embodiment of the present invention provides a steering wheel switch assembly, wherein the edge of the guide component is provided with a clamping portion; wherein,

[0037] When the lever component is deflected and swung to a target position in the height direction relative to the housing, the clamping portion abuts against and clamps the inner wall surface of the housing to limit the swing of the lever component relative to the inner wall surface of the housing.

[0038] By adopting the above technical solution, since a clamping portion is provided on the edge of the guide component in this embodiment, when the lever component is deflected and swung to a target position in the height direction relative to the shell, the clamping portion abuts against and clamps against the inner wall surface of the shell to limit the swing of the lever component relative to the inner wall surface of the shell. Through this structural design, the reliability of the steering wheel switch assembly in this embodiment can be guaranteed.

[0122] More specifically, in the present embodiment, the guide component 500 includes a first universal block 510 and a second universal block 520, wherein when the swing arm 410 swings around the second direction 920, only the first universal block 510 squeezes the first coupling component 600 to approach and abut against the circuit board 200; when the swing arm 410 swings around the first direction 910, the first universal block 510 is linked to drive the second universal block 520 to deflect relative to the housing 300, and the side end of the second universal block 520 squeezes the first coupling component 600 to approach and abut against the circuit board 200; through this structural design, the first universal block 510 and the second universal block 520 will not interfere with each other in the above two actions, and the performance of use is better.

[0123] Furthermore, another implementation of this embodiment provides a steering wheel switch assembly, such as Figure 10-11 As shown, the first universal block 510 and the second universal block 520 are both configured as box-shaped structures, and the first universal block 510 is formed with an extrusion portion 511 on the opposite side walls in the first direction 910, and a first rotating shaft 512 is arranged on the opposite side walls in the second direction 920, the second universal block 520 is provided with an axial hole 521 on the opposite side in the first direction 910 and the opposite side in the second direction 920, and a second rotating shaft 311 is arranged on the inner wall of the housing 300 in the first direction 910.

[0124] Specifically, in this embodiment, the second universal block 520 is rotatably connected to the inner wall surface of the housing 300 and the second rotating shaft 311 through the shaft hole 521 in the first direction 910, and the second universal block 520 is rotatably connected to the first universal block 510 and the first rotating shaft 512 through the shaft hole 521 in the second direction 920.

[0125] More specifically, in the present embodiment, the second universal block 520 is rotatably connected to the inner wall surface of the housing 300 via the axial hole 521 and the second rotating shaft 311 in the first direction 910, and the second universal block 520 is rotatably connected to the first universal block 510 via the axial hole 521 and the first rotating shaft 512 in the second direction 920. Such a simple structure can realize the assembly of the first universal block 510 and the second universal block 520, and the second universal block 520 and the housing 300, thereby simplifying the assembly process and manufacturing cost of the steering wheel switch assembly in the present embodiment.

[0126] Furthermore, another implementation of this embodiment provides a steering wheel switch assembly, wherein the first coupling component 600 includes a pressing block 610 and a first elastic conductive component 611 , and the second coupling component 700 includes a balancing block 710 and a second elastic conductive component 720 .

[0127] Specifically, in the present embodiment, the pressing block 610 is located at a position of the guide component 500 away from the rocker arm 410, the balancing block 710 is arranged opposite to the end of the other end of the rocker arm 410, the first elastic conductive member 611 and the second elastic conductive member 720 are both arranged on the circuit board 200, the first elastic conductive member 611 is located at a position corresponding to the pressing block 610, and the second elastic conductive member 720 is located at a position corresponding to the balancing block 710; a first movable space 810 is provided between the pressing block 610 and the first elastic conductive member 611, a second movable space 820 is provided between the balancing block 710 and the second elastic conductive member 720, and the distance of the first movable space 810 in the vertical direction is greater than the distance of the second movable space 820 in the vertical direction.

[0128] Specifically, in this embodiment, if Figure 5 As shown, when the swing rod 410 swings around the second direction 920, the first universal block 510 is linked to deflect relative to the second universal block 520, and the side end of the first universal block 510 pushes the pressing block 610 to press the first elastic conductive member 611;

[0129] like Figure 6 As shown, when the swing rod 410 swings around the first direction 910, the first universal block 510 is linked to drive the second universal block 520 to deflect relative to the housing 300, and the side end of the second universal block 520 pushes the pressing block 610 to press the first elastic conductive member 611;

[0130] like Figure 7 As shown, when one end of the swing rod 410 is pressed in the axial direction of the swing rod 410 , the other end of the swing rod 410 moves along the axis of the swing rod 410 toward the circuit board 200 and pushes the balance block 710 to press the second elastic conductive component 720 .

[0131] More specifically, the first coupling component 600 in this embodiment includes a pressure block 610 and a first elastic conductive component 611, and the second coupling component 700 includes a balancing block 710 and a second elastic conductive component 720, and a first active space 810 is provided between the pressure block 610 and the first elastic conductive component 611, and a second active space 820 is provided between the balancing block 710 and the second elastic conductive component 720, and the distance of the first active space 810 in the vertical direction is greater than the distance of the second active space 820 in the vertical direction; through such a structural design, when one end of the rocker arm 410 is pressed in the axial direction of the rocker arm 410, the pressure block 610 will not press the first elastic conductive component 611, thereby avoiding interference between the steering wheel switch assembly in this embodiment during the toggling and pressing actions.

[0132] More specifically, in this embodiment, the first elastic conductive component 611 and the second elastic conductive component 720 can both be configured as conductive rubber, and both can be configured as an integral structure and laid as a whole on the circuit board 200, or they can be configured as a split structure and respectively arranged at positions on the circuit board 200 corresponding to the pressure block 610 and the balance block 710.

[0133] Furthermore, another implementation of this embodiment provides a steering wheel switch assembly, such as Figure 8-Figure 9 As shown, a hook 430 is provided between the swing rod 410 and the dial button 420 , and the hook 430 restricts the dial button 420 from being separated from the swing rod 410 .

[0134] Specifically, in this embodiment, a plurality of limit strips 440 are provided at the opening of the swing rod 410 along the radial direction of the opening, and the operating portion 421 is engaged with the plurality of limit strips 440 to be fixed relative to the swing rod 410 .

[0135] More specifically, in this embodiment, the swing arm 410 and the dial button 420 are mutually limited by the hook 430. Since the hook 430 has a relatively simple structure, the processing steps of the steering wheel switch assembly in this embodiment can be further simplified.

[0136] More specifically, in this embodiment, the hook 430 includes a tooth portion provided on the inner wall of the swing rod 410 and a tooth portion provided on the outer wall of the button 420, and the two teeth are used to clamp the two to achieve the clamping of the two.

[0137] More specifically, in this embodiment, the number of the limit bars 440 may be 3, 4, etc., which may be set according to actual design and usage requirements, and this embodiment does not limit this.

[0138] Furthermore, another implementation of this embodiment provides a steering wheel switch assembly, such as Figure 4b As shown, the other end of the swing rod 410 is a flange structure 411, and the side of the balancing block 710 opposite to the swing rod 410 is a concave structure 711 adapted to the flange structure 411, and the other end of the swing rod 410 and one side of the balancing block 710 are embedded with each other.

[0139] Specifically, in this embodiment, the other end of the swing rod 410 is a flange structure 411, and the side of the balance block 710 opposite to the swing rod 410 is a concave structure 711 adapted to the flange structure 411, and the other end of the swing rod 410 and one side of the balance block 710 are mutually embedded; through the arrangement of this structure, the swing rod 410 can swing around the top of the flange structure 411 and the concave structure 711, and the other end of the swing rod 410 can be prevented from interfering with one side of the balance block 710 when swinging. Therefore, this embodiment can achieve a better use effect of the steering wheel switch assembly in this embodiment through the arrangement of this structure.

[0140] More specifically, in this embodiment, the flange structure 411 and the concave structure 711 are both arc surface structures.

[0141] Furthermore, another implementation of this embodiment provides a steering wheel switch assembly, such as Figure 6 As shown, the steering wheel switch assembly further includes a blocking portion 1000 , which is detachably fixedly connected to the base 100 and arranged along the circumference of the second coupling component 700 .

[0142] Specifically, in this embodiment, when the lever component 400 deflects and swings relative to the height direction 310 of the housing 300 , the other end of the lever component 400 at least partially abuts against the blocking portion 1000 .

[0143] More specifically, in this embodiment, the blocking part 1000 is arranged on the peripheral side of the second coupling part 700. Based on the arrangement of this structure, when the swing rod 410 is deflected to a certain angle, the other end of the lever component 400 abuts against the blocking part 1000, and the blocking part 1000 can limit the lever component 400 from moving downward to trigger the pressing function. Therefore, through the arrangement of this structure, the steering wheel switch assembly in this embodiment can be further prevented from triggering the pressing function when the toggle function is realized, and the independence of the steering wheel switch assembly when toggling and pressing can be ensured, which can further improve the reliability of the steering wheel switch assembly in this embodiment.

[0144] More specifically, in this embodiment, the blocking portion 1000 is a block structure. When the lever component 400 swings, the lever component 400 will deflect relative to the balance block 710, and one side of the lever component 400 will abut against the blocking portion 1000. The specific size of the abutment area depends on the swing amplitude of the lever component 400, and this embodiment does not make specific requirements.

[0145] Furthermore, another implementation of this embodiment provides a steering wheel switch assembly, such as Figure 4a-4f As shown, a clamping portion is provided on the edge of the guide component 500 .

[0146] Specifically, in this embodiment, when the lever component 400 is deflected and swung to the target position relative to the height direction 310 of the housing 300, the clamping portion abuts against and clamps the inner wall surface of the housing 300 to limit the swing of the lever component 400 relative to the inner wall surface of the housing 300.

[0147] More specifically, in this embodiment, the clamping portion is a groove formed on the edge of the second universal block 520, and a protrusion is provided on the inner wall surface of the outer shell 300. When the lever component 400 is deflected and swung to the target position relative to the height direction 310 of the outer shell 300, the groove and the protrusion are engaged with each other to limit the swing of the lever component 400 relative to the inner wall surface of the outer shell 300.

[0148] More specifically, in the present embodiment, since a clamping portion is provided on the edge of the guide component 500, when the lever component 400 is deflected and swung to a target position in the height direction 310 relative to the outer shell 300, the clamping portion abuts against and clamps against the inner wall surface of the outer shell 300 to limit the swing of the lever component 400 relative to the inner wall surface of the outer shell 300. Through this structural design, the reliability of the steering wheel switch assembly in the present embodiment can be ensured.

[0149] During the assembly process of the steering wheel switch assembly provided in this embodiment:

[0150] S1: Fig.13 As shown, the dial button 420 is mounted on the swing rod 410 to form the dial rod component 400;

[0151] S2: Fig.14 As shown, the pressing block 610 and the second universal block 520 are installed in the housing;

[0152] S3: Fig.15 As shown, the first universal block 510 is installed in the second universal block 520;

[0153] S4: Fig.16 As shown, the lever component 400 is installed in the first universal block 510;

[0154] S5: Fig.17 As shown, the balancing weight 710 is reversely loaded into the housing;

[0155] S5: Fig.18 As shown, conductive rubber is installed on the circuit board 200, and the circuit board 200 installed with the guide rubber is installed into the base 100, and then installed into the bottom of the housing 300 with its back facing away, and fastened by screws.

[0156] Specifically, in step S1, three ribs are provided on the top of the rocker 410, and three grooves are designed corresponding to the dial button 420, so as to achieve positioning with zero clearance.

[0157] In step S2 , the pressing block 610 should be installed below the housing 300 in the height direction 310 of the housing 300 , and different markings are provided around the second universal block 520 to prevent assembly misalignment.

[0158] In step S4 , an anti-misalignment mark is also provided on the circumference of the swing rod 410 to prevent the outer wall surface of the swing rod 410 from being misaligned with the inner wall surface of the housing 300 .

[0159] In step S5 , there should be a single-side gap of 0.05 mm between the outer wall surface of the balancing weight 710 and the inner wall surface of the inner assembly groove of the housing 300 .

[0160] The steering wheel switch assembly provided in this embodiment can realize two functions: toggle and press. During use:

[0161] When the user presses the button on the operating part 421 in the first direction 910, the lever component 400 deflects around the second direction 920. At this time, the swing rod 410 drives the first universal block 510 to deflect, and the second universal block 520 does not deflect. The pressing block 610 is pushed by the squeezing part 511 on the side of the first universal block 510, and the pressing block 610 squeezes the conductive rubber.

[0162] When the user presses the button on the operating part 421 in the second direction 920, the lever component 400 deflects around the first direction 910. At this time, the swing rod 410 drives the first universal block 510 to deflect, and drives the second universal block 520 to deflect, and pushes the pressing block 610 through the side of the second universal block 520, and the pressing block 610 squeezes the conductive rubber;

[0163] In the above two processes, due to the effect of the blocking portion 1000 , the lever component 400 does not move in the vertical direction.

[0164] When the user presses the middle position of the operating portion 421 , the other end of the swing rod 410 moves along the axis of the swing rod 410 toward the circuit board 200 , and pushes the balance block 710 to press the conductive rubber.

[0165] It should be noted that the first universal block 510 and the second universal block 520 are both gap-positioned in the first direction 910 and the second direction 920. Due to the reverse elastic force of the conductive rubber, the rocker arm 410 can be relatively still in the vertical direction relative to the first universal block 510. The movable gap between the rocker arm 410 and the first universal block 510 in the vertical direction is set to 2.3 mm, that is, the rocker arm 410 will reach the extreme position when it moves down 2.3 mm.

[0166] Specifically, when the user presses the button on the operating part 421 located in the first direction 910, the swing rod 410 component will deflect 6° around the second direction 920, and the first universal block 510 pressure head position will move down, thereby acting on the pressure block 610. The pressure block 610 will then rotate 9°, and the other side of the pressure block 610 will rotate to act on the conductive rubber pressure head, which will deform and force the conductive particles inside it to move down and contact the conductive disk, ultimately achieving signal connection output. The contact stroke in this process can be: swing rod 410: 6°, pressure block 610: 9°; of course, it can also be other values, for example, the maximum stroke: swing rod 410: 10°, pressure block 610: 12°; when the user presses the button on the operating part 421 located in the second direction 920, the principle is similar to the above, and this embodiment will not be repeated one by one.

[0167] When the user presses the middle position of the operating part 421, the dial button 420 links the rocker 410 and the balance block 710 to move down 1.5mm, causing the conductive rubber to deform, forcing the conductive particles inside to move down and contact the conductive disk, thus achieving signal connection and output. The contact stroke in this process can be 1.5mm or 2.3mm.

[0168] It should be understood that this embodiment is not limited to the above-mentioned itinerary, and its specific setting should be based on actual design and usage requirements.

[0169] The steering wheel switch assembly provided in this embodiment is more convenient to use when applied to a car. The buttons on the first direction 910 can be the high beam and the low beam, the buttons on the second direction 920 can be the left turn signal and the left turn signal, and the middle button can be the headlight on button.

[0170] Of course, the steering wheel switch assembly is not limited to setting the above functions, but can also be applied to other scenarios. The specific settings should be based on actual needs and are not limited in this embodiment.

[0173] Specifically, since the steering wheel assembly in this embodiment includes the steering wheel switch assembly of the above structure, and the steering wheel switch assembly integrates both the toggle and press functions, its functions are more comprehensive. In addition, the CAS surface of the product is reduced. The steering wheel switch assembly with this structure can save space for the development of vehicle function realization, reduce the development of related necessary functional parts, reduce vehicle development costs, and shorten the vehicle development cycle.
