Description

Technical Field

[0001] This utility model relates to a universal automotive steering wheel switch, belonging to the field of automotive switch technology. Background Technology

[0002] Existing automotive steering wheel switches integrate a large number of buttons, requiring the integration of numerous pressing components driven by button presses and guide posts for guiding the buttons. This results in a small guiding area for each button, leading to poor guiding performance and a tendency for buttons to jam. A search revealed patent document CN 217035487 U, which discloses a compact automotive steering wheel switch. This switch includes a housing, several buttons, and pressing components corresponding to the number of buttons. The housing has guide components extending in a single direction for each button. Each button has a guide sleeve on its outer periphery that matches the shape and size of the guide component. At least one guide component has at least one guide groove, extending in the same direction as the corresponding guide component. The guide groove is open towards the corresponding guide sleeve. A guide strip is located within the guide groove of the guide sleeve. The housing has sliding sleeves for each pressing component, with each pressing component slidably mounted within the sliding sleeve. This switch improves the smoothness of guidance by increasing the guiding contact area through the opening of guide grooves on the guide component, in conjunction with the guide sleeve and guide strip.

[0003] However, the backlit button of this switch corresponds to an irregularly shaped pressing part with a pressing part, while other buttons use cylindrical pressing parts. This means that the pressing parts within a single switch cannot be standardized, increasing processing costs. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a universal automotive steering wheel switch to at least solve the problems mentioned in the background art.

[0005] The objective of this utility model is achieved through the following technical solution:

Below the switch buttons and the light-transmitting button are a corresponding number of universal cylindrical pressing members, with a circuit board below each cylindrical pressing member. A guide sleeve is provided at the bottom of each switch button and the light-transmitting button. Inside the housing are guide members that are positioned opposite to the guide sleeves and whose shape and size are adapted to them. Furthermore, the housing contains sliding sleeves corresponding to the cylindrical pressing members, with each cylindrical pressing member slidably installed within the sliding sleeves.

[0007] Furthermore, the cylindrical pressing member is a stepped structure consisting of a pressing part and a guide part disposed at one end of the pressing part near the circuit board. The sliding sleeve has a stepped hole at its axis that is adapted to the stepped structure. The pressing part slides along the inside of the sliding sleeve, while the guide part is used to realize sliding guidance.

[0008] Furthermore, the pressing part is a cylindrical structure adapted to the sliding sleeve shaft hole, and the guide part is a circular or square boss provided at one end of the cylindrical structure near the circuit board.

[0009] Furthermore, the pressing part and the guiding part are integrally molded elastic rubber bodies.

[0010] Furthermore, at least one part of the sliding sleeve corresponding to each of the aforementioned switch buttons and light-transmitting buttons overlaps with the side of the corresponding guide member, and the sliding sleeve is provided with an anti-interference notch facing the corresponding button side.

[0011] Furthermore, a light-concentrating cavity is provided inside the guide member corresponding to the light-transmitting button, and a light-emitting element for illuminating the light-concentrating cavity is provided on the circuit board. The sliding sleeve corresponding to the light-transmitting button is provided at the corner of the guide member, and the corresponding cylindrical pressing element is located inside the sliding sleeve.

[0012] Furthermore, the housing includes a base, an intermediate body, and a bottom cover. The circuit board is disposed between the intermediate body and the bottom cover. The guide and sliding sleeve are disposed within the intermediate body. The base is located around the switch button to achieve circumferential wrapping. A flexible sealing gasket is provided on the side of the circuit board near the cylindrical pressing member.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] like Figure 1-Figure 5As shown, the first embodiment of this utility model provides a universal automotive steering wheel switch, including a housing 1. The housing 1 has several switch buttons 2, and at least one switch button 2 is a light-transmitting button 3. A corresponding number of cylindrical pressing members 4 are provided below the switch buttons 2 and the light-transmitting button 3, and a circuit board 5 is provided below the cylindrical pressing members 4. A guide sleeve 6 is provided at the bottom of each switch button 2 and the light-transmitting button 3. A guide member 7, whose position and shape are adapted to the guide sleeve 6, is provided inside the housing 1. Furthermore, a sliding sleeve 8, corresponding to the cylindrical pressing members 4, is provided inside the housing 1, and each cylindrical pressing member 4 is slidably installed within the sliding sleeve 8. The main improvement of this embodiment is that the pressing members corresponding to the switch buttons 2 and the light-transmitting button 3 are all universal cylindrical pressing members, allowing for batch processing using a single mold during the manufacturing process, greatly saving manufacturing costs.

[0026] Specifically, the cylindrical pressing member 4 is a stepped structure consisting of a pressing part 41 and a guide part 42 located at one end of the pressing part 41 near the circuit board 5. The sliding sleeve 8 has a stepped hole at its axis that matches the stepped structure. The pressing part 41 slides within the sliding sleeve 8, while the guide part 42 guides the sliding motion, making the pressing force more stable and the drive smoother. The pressing part 41 is a cylindrical structure that matches the axial hole of the sliding sleeve 8, and the guide part 42 is a circular or square boss located at one end of the cylindrical structure near the circuit board 5. The pressing part 41 and the guide part 42 are integrally molded elastic rubber bodies. When the button is pressed, the guide part 7 and the guide sleeve 6 engage to achieve downward guiding, and the cylindrical pressing member 4 moves down to touch the circuit board 5, generating an electrical signal output, and then returns to its original position due to its own elasticity.

[0027] At least one part of the sliding sleeve 8 corresponding to each of the aforementioned switch buttons 2 and light-transmitting buttons 3 overlaps with the side of the corresponding guide member 7, and the sliding sleeve has an anti-interference notch 9 facing the corresponding button side. The guide member 7 corresponding to the light-transmitting button 3 has a focusing cavity 31, and a light-emitting element is provided on the circuit board 5 to illuminate the focusing cavity 31. The circuit board 5 illuminates when powered on, thereby illuminating the focusing cavity 31. The sliding sleeve 8 corresponding to the light-transmitting button 3 is located at the corner of the guide member 7, and its corresponding cylindrical pressing member 4 is located inside the sliding sleeve 8. The cylindrical pressing member 4 is controlled by the sliding and pressing action of the light-transmitting button 3. Placing the sliding sleeve 8 at the corner of the guide member 7 improves light transmission.

[0028] like Figure 1-Figure 5As shown, based on the first embodiment, the second embodiment of this utility model provides a universal automotive steering wheel switch. The housing 1 includes a base 11, an intermediate body 12, and a bottom cover 13. The circuit board 5 is disposed between the intermediate body 12 and the bottom cover 13. The guide 7 and the sliding sleeve 8 are disposed inside the intermediate body 12. The base 11 is located around the switch button 2 to achieve circumferential wrapping. A flexible sealing gasket 10 is provided on the side of the circuit board 5 near the cylindrical pressing member 4. The bottom of the flexible sealing gasket 10 is provided with a placement groove, and the top is provided with several protrusions corresponding to the cylindrical pressing member 4. During assembly, the circuit board 5 can be placed in the groove of the flexible sealing gasket 10. The periphery of the groove of the flexible sealing gasket 10 is closely attached to the inner wall of the base 11, which can ensure that the circuit board 5 has good waterproof and dustproof effects.

[0029] In this embodiment, the bottom end of the guide portion 42 of the cylindrical pressing member 4 is provided with a guide groove that matches the protrusion of the flexible sealing gasket 10, so that the guide portion 42 can better achieve sliding guidance, making the pressing force more stable and the driving smoother.

[0030] When the button is pressed, the guide 7 and guide sleeve 6 engage to guide the button downwards. The cylindrical pressing part 4 then moves downwards to touch the protrusion of the waterproof flexible pad 10 before touching the circuit board 5 for circuit control. The flexible sealing pad 10 can be a thin rubber sheet, which, while not affecting button operation, prevents water or dust from entering the circuit board area through the gaps around the switch button 2 and the light-transmitting button 3, thus improving the service life of the switch.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to restrict the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments without departing from the technical solution of the present utility model and based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
