Description

Technical Field

[0001] This application relates to the field of steering wheel technology, and more specifically, to a steering wheel assembly. Background Technology

[0002] With the continuous development of the automotive industry, the steering wheel, as a core component for vehicle control, has also undergone continuous evolution in design and function. Modern car steering wheels not only perform the basic function of steering control but also integrate various auxiliary functions, such as horn, multimedia control, and cruise control. Among these, the horn, as an important vehicle safety warning device, typically relies on an airbag module on the steering wheel for its triggering mechanism.

[0003] The current horn function is mainly achieved by incorporating conductive wires inside the steering wheel. When the driver presses the airbag, the mechanical movement of the airbag activates these wires, triggering the horn to sound. Because the horn function relies on mechanical contact between components inside the steering wheel, under certain road conditions, such as bumpy surfaces or sharp turns, relative movement may occur between these components, leading to collisions and abnormal noises. This noise not only affects the driving experience but may also potentially impact the stability of the steering wheel's internal structure. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0037] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0038] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0039] As disclosed in the background section, under certain adverse road conditions (such as bumpy roads or sharp turns), the components used to implement the horn function may experience relative movement, leading to collisions between the components and generating abnormal noises. These noises not only affect the driving experience but may also potentially impact the stability of the steering wheel's internal structure. Embodiments of this application provide a steering wheel assembly that at least addresses this technical problem.

[0040] Please refer to Figure 1 , Figure 2 The steering wheel assembly 10 provided in the embodiments of this application includes a fixed unit, a movable unit, and a buffer 400. The movable unit is used to move relative to the fixed unit and to trigger the steering wheel to make a sound during the movement relative to the fixed unit. The buffer 400 is disposed between the fixed unit and the movable unit and is used to reduce the collision between the movable unit and the fixed unit in two directions forming an angle.

[0041] The fixing unit is the main structural support part of the steering wheel. For example, the fixing unit includes the steering wheel frame 100, which is used to fix the position of the entire steering wheel assembly 10 and provide a stable mounting base.

[0042] The movable unit can move relative to the fixed unit to enable the steering wheel to make a sound. When the movable unit is pressed, it will move relative to the fixed unit and trigger the sound.

[0043] The buffer 400 is disposed between the fixed unit and the moving unit, playing a key role in buffering and noise reduction. The buffer 400 can simultaneously reduce the collision between the moving unit and the fixed unit in two directions at an angle (such as the horizontal and vertical directions). This design ensures that when the collision between the moving unit and the fixed unit occurs in either of the above directions, the buffer 400 can effectively reduce abnormal noise.

[0044] In some adverse road conditions, the moving unit and the fixed unit used to trigger the steering wheel clattering function will move relative to each other. At this time, since a buffer 400 is provided between the fixed unit and the moving unit, the buffer 400 can reduce the collision between the moving unit and the fixed unit in two directions with an included angle, thereby reducing the abnormal noise caused by the collision between the fixed unit and the moving unit to a certain extent.

[0045] Please refer to Figure 3 , Figure 4In some embodiments, the fixed unit includes a steering wheel frame 100 and a fastener 300 connected to each other, and the movable unit includes a squeak assembly 200 for moving relative to the fastener 300 and triggering the squeaking of the steering wheel. A buffer 400 is disposed between the squeak assembly 200 and the fastener 300 for mitigating the collision between the squeak assembly 200 and the fastener 300 in two directions forming an angle.

[0046] The fastener 300 is fixedly connected to the steering wheel frame 100. The horn assembly 200 and the steering wheel frame 100 are respectively provided with a positive horn contact 800 and a negative horn contact 900. During the movement of the horn assembly 200 relative to the fastener 300, the positive horn contact 800 will come into contact with the negative horn contact 900, thereby triggering the horn to sound.

[0047] Since the clicker assembly 200 can move relative to the fastener 300, a buffer 400 is disposed between the clicker assembly 200 and the fastener 300. The buffer 400 can reduce the collision between the clicker assembly 200 and the fastener 300 in two directions at an angle.

[0048] To facilitate the reset of the turntable assembly 200, a first elastic reset member 600 is provided between the turntable assembly 200 and the steering wheel frame 100. The first elastic reset member 600 can be a spring or a sheet, etc., as long as it can reset the turntable assembly 200 after it is pressed. There is no limitation on this.

[0049] In addition, the active unit also includes an airbag 500 fixedly connected to the audible button assembly 200. The fixed connection between the airbag 500 and the audible button assembly 200 includes, but is not limited to, screwing, snap-fitting, or bonding. For example, the airbag 500 is provided with a snap-fit ​​shaft, and the audible button assembly 200 is provided with a snap-fit ​​hole. The snap-fit ​​shaft and the snap-fit ​​hole are engaged to achieve a fixed connection between the airbag 500 and the audible button assembly 200.

[0050] When the driver presses the airbag 500, the airbag 500 will cause the snorkel assembly 200 to move relative to the fastener 300 until the positive horn contact 800 and the negative horn contact 900 come into contact, thus triggering the snorkeling. During this process, the first elastic reset member 600 is compressed. When the driver releases the airbag 500, the airbag 500 and the snorkel assembly 200 will move relative to the fastener 300 under the action of the first elastic reset member 600 until they are reset. The buffer member 400 can also reduce the collision between the snorkel assembly 200 and the fastener 300 during the movement of the snorkel assembly 200 relative to the fastener 300.

[0051] In some embodiments, the number of fasteners 300 and buffers 400 is the same and there are multiple fasteners 300 and buffers 400. For example, the number of fasteners 300 and buffers 400 is four, and the four fasteners 300 and the four buffers 400 correspond one-to-one.

[0052] Please refer to Figure 5 In some other embodiments, the fixed unit includes a steering wheel frame 100 and a squeegee assembly 200 connected to each other, the movable unit includes a fastener 300 for moving relative to the squeegee assembly 200 and triggering the squeegee of the steering wheel, and a buffer 400 is disposed between the squeegee assembly 200 and the fastener 300 for mitigating the collision between the squeegee assembly 200 and the fastener 300 in two directions forming an angle.

[0053] The audible button assembly 200 is fixedly connected to the steering wheel frame 100. Since the fastener 300 can move relative to the audible button assembly 200, a buffer 400 is disposed between the audible button assembly 200 and the fastener 300. The buffer 400 can reduce the collision between the audible button assembly 200 and the fastener 300 in two directions at an angle.

[0054] The active unit also includes an airbag 500 connected to the fastener 300, and a second elastic reset member 700 is provided between the airbag 500 and the clicker assembly 200.

[0055] The airbag 500 is fixedly connected to the fastener 300. The fixed connection between the airbag 500 and the fastener 300 includes, but is not limited to, screw connection, snap connection or adhesive connection. For example, the airbag 500 is provided with a snap-fit ​​part, and the fastener 300 is provided with a snap-fit ​​groove. The snap-fit ​​part and the snap-fit ​​groove engage to achieve a fixed connection between the airbag 500 and the fastener 300.

[0056] The airbag 500 and the horn assembly 200 are respectively provided with a positive horn contact 800 and a negative horn contact 900, or the airbag 500 and the steering wheel frame 100 are respectively provided with a positive horn contact 800 and a negative horn contact 900. During the movement of the fastener 300 relative to the horn assembly 200, the positive horn contact 800 will come into contact with the negative horn contact 900, thereby triggering the horn to be sounded.

[0057] The second elastic reset element 700 can be a spring or a sheet, as long as it can reset the airbag 500 and the fastener 300 after the airbag 500 is pressed. There are no restrictions on this.

[0058] When the driver presses the airbag 500, the airbag 500 will cause the fastener 300 to move relative to the squeegee assembly 200 until the positive horn contact 800 and the negative horn contact 900 come into contact, thus triggering the squeegee. During this process, the second elastic reset member 700 is compressed. When the driver releases the airbag 500, the airbag 500 and the fastener 300 will move relative to the squeegee assembly 200 under the action of the second elastic reset member 700 until they are reset. The buffer member 400 can also reduce the collision between the squeegee assembly 200 and the fastener 300 during the movement of the fastener 300 relative to the squeegee assembly 200.

[0059] In some embodiments, the fastener 300 is a fastening pin, and the buffer 400 is used to simultaneously mitigate the impact between the clicker assembly 200 and the fastening pin in both the axial and radial directions. In other alternative embodiments, the fastener 300 may also be a fastening bolt.

[0060] Under certain adverse road conditions, relative movement occurs between the squeak assembly 200 and the fastening pin. At this time, since a buffer 400 is provided between the squeak assembly 200 and the fastening pin, the buffer 400 can reduce the collision between the squeak assembly 200 and the fastening pin in two directions that form an angle, thereby reducing the abnormal noise generated by the collision between the squeak assembly 200 and the fastening pin to a certain extent. The two directions that form an angle are the axial and radial directions of the fastening pin, respectively.

[0061] Please refer to Figure 6 The buffer 400 includes a first buffer segment 410 and a second buffer segment 420 arranged at an angle, the angle between the first buffer segment 410 and the second buffer segment 420 being optionally 90°. In other embodiments, the angle between the first buffer segment 410 and the second buffer segment 420 may be greater than or less than 90°.

[0062] The first buffer section 410 and the second buffer section 420 are used to mitigate the collision between the moving unit and the fixed unit in two directions forming an angle. When the fastener 300 is a fastening pin, the first buffer section 410 and the second buffer section 420 are used to mitigate the collision between the clicker assembly 200 and the fastening pin in the axial and radial directions of the fastening pin, respectively.

[0063] The first buffer section 410 is mainly responsible for absorbing and dispersing the impact force between the soundpad assembly 200 and the fastening pin in the axial direction of the fastening pin, thereby reducing the collision between the soundpad assembly 200 and the fastening pin in the axial direction of the fastening pin to reduce abnormal noise; the second buffer section 420 is mainly responsible for absorbing and dispersing the impact force between the soundpad assembly 200 and the fastening pin in the radial direction of the fastening pin, thereby reducing the collision between the soundpad assembly 200 and the fastening pin in the radial direction of the fastening pin to reduce abnormal noise.

[0064] Since the first buffer section 410 and the second buffer section 420 are arranged at a certain angle, they can together form a three-dimensional buffer system, which mainly covers the impact between the soundboard assembly 200 and the fastening pin in the axial and radial directions of the fastening pin.

[0065] The first buffer segment 410 and the second buffer segment 420 are integrally formed structures. The first buffer segment 410 is bent relative to the second buffer segment 420, so that the first buffer segment 410 and the second buffer segment 420 are set at an angle. Of course, in other embodiments, the first buffer segment 410 and the second buffer segment 420 can also be set separately.

[0066] In some embodiments, a flange 421 is provided at the end of the second buffer section 420 away from the first buffer section 410, and the flange 421 extends radially along the fastening pin.

[0067] In an alternative embodiment, flange 421 faces and abuts against the clicker assembly 200, and buffer 400 is fixed relative to fastening pin, for example, buffer 400 is snapped or bonded to fastening pin.

[0068] During the process of pressing the airbag 500 to move the audible button assembly 200 relative to the fastening pin and during the process of resetting the audible button assembly 200, the audible button assembly 200 will move relative to the buffer 400. During the above process, when the flange 421 abuts against the audible button assembly 200, the obstruction caused to the audible button assembly 200 is small, which is not likely to affect the driver's operating feel and the realization of the audible button function.

[0069] During the process of pressing the airbag 500 to move the fastening pin relative to the audible button assembly 200 and during the process of the fastening pin resetting, the buffer 400 will move relative to the audible button assembly 200. During the above process, when the flange 421 abuts against the audible button assembly 200, the obstruction to the fastening pin is small, which is less likely to affect the driver's operating feel and the realization of the audible button function.

[0070] The flange 421 provides good positioning for the audible button assembly 200, resulting in a better surface clearance between the airbag 500 and the steering wheel. On the other hand, because the flange 421 has a small area, it is less likely to obstruct the movement of the audible button assembly 200, thus affecting the audible feel or causing jamming during the audible process.

[0071] In other alternative embodiments, please refer to Figure 7 The flange 421 can also face and abut against the fastening pin, at which time the buffer 400 can be fixed to either the fastening pin or the clicker assembly 200. For example, the buffer 400 can be snapped or glued to the clicker assembly 200.

[0072] In some embodiments, the fastening pin includes a pin 310 and a flange 320 connected to one end of the pin 310. The clicker assembly 200 has a through hole 210, through which the pin 310 passes. A first buffer section 410 is disposed between one of the surfaces of the clicker assembly 200 on the axial direction of the pin 310 and the flange 320. A second buffer section 420 is disposed between the inner wall of the through hole 210 and the pin 310.

[0073] When the squeak assembly 200 and the fastening pin move relative to each other along the axial direction of the pin shaft 310, the first buffer section 410 can reduce the collision between the squeak assembly 200 and the flange 320, thereby reducing abnormal noise; when the squeak assembly 200 and the fastening pin move relative to each other along the radial direction of the pin shaft 310, the second buffer section 420 can reduce the collision between the squeak assembly 200 and the pin shaft 310, thereby reducing abnormal noise.

[0074] The audible button assembly 200 has a front and a back in the axial direction of the pin 310. When the audible button assembly 200 is fixedly connected to the airbag 500, the front of the audible button assembly 200 faces the airbag 500. The first buffer section 410 is located between the front of the audible button assembly 200 and the flange 320. The first elastic reset member 600 is located between the back of the audible button assembly 200 and the steering wheel frame 100.

[0075] With the audible button assembly 200 fixedly connected to the steering wheel frame 100, the front of the audible button assembly 200 faces the steering wheel frame 100. The first buffer section 410 is located between the front of the audible button assembly 200 and the flange 320. The second elastic reset member 700 is located between the back of the audible button assembly 200 and the airbag 500. Specifically, the second elastic reset member 700 can be located between the back of the audible button assembly 200 and the housing of the airbag 500.

[0076] In some embodiments, the inner wall of the through hole 210 is provided with a slope 220, and the distance between the slope 220 and the pin 310 gradually increases in the direction along the axial direction of the pin 310 and toward the first buffer section 410 of the clicker assembly 200.

[0077] In the direction along the axial direction of the pin 310 and towards the first buffer section 410, i.e., the front of the sounder assembly 200 faces the first buffer section 410, the distance between the inclined surface 220 and the pin 310 gradually increases. During the process of assembling the sounder assembly 200 to the fastening pin, the opening of the through hole 210 near the top of the inclined surface 220 is relatively large, which facilitates the quick assembly of the second buffer section 420 between the sounder assembly 200 and the fastening pin.

[0078] After the snap button assembly 200 is assembled with the fastening pin, there is a gap between the inclined surface 220 and the pin 310. When the flange 421 is deformed by a force along the radial direction of the fastening pin, the existence of this gap makes it difficult for the snap button assembly 200 and the pin 310 to collide.

[0079] Furthermore, during the process of triggering the steering wheel, the distance between the part of the inclined surface 220 that contacts the flange 421 and the pin 310 gradually increases, which gradually reduces the squeezing force of the inclined surface 220 on the flange 421, thus making it less likely to affect the pressing effect.

[0080] When a flange 421 is provided at one end of the second buffer section 420 away from the first buffer section 410 and the flange 421 faces the inner wall of the through hole 210, an inclined guide surface may also be provided on the flange 421 so as to contact the inclined surface 220 of the inner wall of the through hole 210 to guide the clicker assembly 200, thereby realizing the rapid assembly of the clicker assembly 200.

[0081] In the above embodiments, the clicker assembly 200 mainly includes a clicker 230; however, in other embodiments, please refer to... Figure 8 The soundboard assembly 200 includes a soundboard 230, a damping element 240, and a bushing 250. The damping element 240 is disposed between the soundboard 230 and the bushing 250. A buffer 400 is disposed between the bushing 250 and the fastener 300. The buffer 400 is used to reduce the impact between the bushing 250 and the fastener 300 in two directions at an angle.

[0082] In the embodiments of this application, the buffer 400 is made of an elastic material. The buffer 400 made of an elastic material can provide good cushioning and noise reduction effects.

[0083] It should be noted that the elastic material includes, but is not limited to, various types of rubber, TPE, and other thermoplastic elastomers. The elastic material is typically EPDM or silicone. The damping element 240 can also be made from any of the aforementioned elastic materials.

[0084] When the fastener 300 is a fastening pin, a through hole 210 is provided on the bushing 250, and the fastening pin passes through the through hole 210. A bevel 220 may also be provided on the inner wall of the through hole 210. The buffer 400 reduces the collision between the bushing 250 and the fastening pin in the axial and radial directions. Specifically, the first buffer section 410 is provided between the front of the bushing 250 and the flange 320 of the fastening pin, and the second buffer section 420 is provided between the inner wall of the through hole 210 and the pin shaft 310 of the fastening pin.

[0085] It should be noted that during vehicle operation, due to the vehicle body's modal characteristics, the steering system may resonate at specific frequencies. This vibration is transmitted to the driver's side airbag 500 through the steering column interface, causing the airbag 500 to move under the influence of resonance. Since the damping element 240, located between the clicker 230 and the bushing 250, is made of elastic material, the kinetic energy generated by the moving unit in the direction of movement is converted into heat energy through compression of the damping element 240, achieving an energy absorption effect. This energy is less likely to be transmitted to the steering wheel frame 100, thus achieving the purpose of vibration damping.

[0086] The buffer 400 mainly provides dual protection in the axial and radial directions of the fastening pin. When the bushing 250 and the fastening pin move relative to each other along the axial direction of the fastening pin, the first buffer section 410 can absorb the impact force and prevent the bushing 250 from directly colliding with the flange 320 of the fastening pin. When the bushing 250 and the fastening pin move relative to each other along the radial direction of the fastening pin, the second buffer section 420 can absorb the impact force and prevent the bushing 250 from directly colliding with the pin shaft 310 of the fastening pin.

[0087] The technical effects of the steering wheel assembly 10 provided in this application embodiment include at least the following: a buffer 400 is provided between the audible plug assembly 200 and the fastening pin. The buffer 400 can reduce the collision between the audible plug assembly 200 and the fastening pin in the axial and radial directions, thereby reducing the abnormal noise generated by the collision between the audible plug assembly 200 and the fastening pin to a certain extent; the first buffer section 410 of the buffer 400 is mainly responsible for absorbing and dispersing the impact force between the audible plug assembly 200 and the fastening pin in the axial direction of the fastening pin, thereby reducing the impact force between the audible plug assembly 200 and the fastening pin in the axial direction of the fastening pin. The collision between the 0 and the fastening pin is reduced to alleviate abnormal noise; the second buffer section 420 of the buffer member 400 is mainly responsible for absorbing and dispersing the impact force between the squeaker assembly 200 and the fastening pin in the radial direction of the fastening pin, thereby reducing the collision between the squeaker assembly 200 and the fastening pin in the radial direction of the fastening pin to reduce abnormal noise; when the flange 421 on the second buffer section 420 abuts against the squeaker assembly 200, it causes less obstruction to the squeaker assembly 200, and is less likely to affect the driver's operating feel and the realization of the squeaker function; effectively reducing the shaking of the airbag 500 and improving the durability of the airbag 500.

[0088] In summary, this application provides a steering wheel assembly 10, which mainly includes a steering wheel frame 100, a squeegee assembly 200, and a fastening pin. Under some adverse road conditions, relative movement occurs between the squeegee assembly 200 and the fastening pin. At this time, since a buffer 400 is provided between the squeegee assembly 200 and the fastening pin, the buffer 400 can simultaneously reduce the collision between the squeegee assembly 200 and the fastening pin in both the axial and radial directions, thereby reducing the abnormal noise generated by the collision between the squeegee assembly 200 and the fastening pin to a certain extent and improving the driver's driving experience.
