[0041] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0042] In the present disclosure, unless otherwise stated, directional words such as "upper, lower, left, right" are usually defined by the direction of the drawing, and "inner" and "outer" refer to the inside and outside of the relevant parts. In addition, the terms "first", "second", etc. are only used to distinguish descriptions and cannot be understood as indicating or implying relative importance.

[0043] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0044] With the popularity of electric vehicles, people have higher and higher requirements for driving sound and physical comfort. At present, the steering wheels of many vehicles will vibrate or make abnormal noises in a certain speed range (such as above 120km / h) or special road conditions (such as bumpy roads). These vibrations or abnormal noises are particularly disturbing to the driver in electric vehicles. Among them, these vibrations are caused by the rigid connection between the steering wheel and the steering column (such as fixed by nuts), and the steering column transmits the vibration of the chassis to the steering wheel; and most of these abnormal noises are caused by the vibration of the airbag module and the spring steel bar or steering wheel frame that fixes the airbag module. In order to reduce these vibrations and abnormal noises, a corresponding damping device will be arranged on the steering wheel. The damping device is generally composed of an elastomer and a mass block. The larger the mass block, the more obvious the vibration reduction effect. At present, the mainstream is to use the airbag module arranged on the steering wheel as a vibration reduction mass block.

[0045] There is relative movement between the airbag module and the horn bracket of the steering wheel in the related art, that is, the airbag module and the horn bracket are not relatively fixed, so when the airbag module is pressed, the airbag module and the horn bracket may touch each other, causing abnormal noise and affecting driving comfort.

[0046] For this reason, Figure 1-Figure 8 As shown, one aspect of the present disclosure provides a steering wheel including an airbag module 8 and a horn bracket 2 .

[0047] The airbag module 8 is connected to the speaker bracket 2 , and the airbag module 8 and the speaker bracket 2 at least partially abut against each other on one side facing each other, so as to limit the mutual movement of the airbag module 8 and the speaker bracket 2 .

[0048] In the above technical solution, the airbag module 8 and the speaker bracket 2 are connected to each other, and the airbag module 8 and the speaker bracket 2 are abutted against each other so that there is no movable gap between the two. Thus, the airbag module 8 and the speaker bracket 2 remain relatively fixed as a whole. In other words, the airbag module 8 and the speaker bracket 2 together serve as a vibration-absorbing mass block, which can increase the size of the mass block and improve the vibration-absorbing effect. In addition, the relatively fixed design of the airbag module 8 and the speaker bracket 2 can avoid contact between the airbag module 8 and the speaker bracket 2 when the airbag module 8 is pressed, avoid abnormal noise, and improve driving comfort.

[0049] Optionally, in one embodiment of the present disclosure, one of the airbag module 8 and the speaker bracket 2 is provided with a support portion 23, and the support portion 23 extends toward the other of the airbag module 8 and the speaker bracket 2 and abuts against the other. The support portion 23 can play an extended connection role, so that the airbag module 8 and the speaker bracket 2 can be not tightly attached, and can still maintain a supporting role. That is, when there is a certain gap between the airbag module 8 and the speaker bracket 2, the support portion 23 achieves a supporting role, and the airbag module 8 and the speaker bracket 2 can still remain in a relatively fixed state, which can facilitate assembly operations.

[0050] Of course, in other embodiments, the airbag module 8 and the speaker bracket 2 may partially fit together on one side facing each other to produce a mutual support effect.

[0051] Optionally, in one embodiment of the present disclosure, the support portion 23 is connected to the speaker bracket 2, and a first mounting hole 24 is provided on the speaker bracket 2. The support portion 23 includes a mounting end and a contact end connected to each other, the mounting end is passed through the first mounting hole 24, the contact end extends in a direction away from the speaker bracket 2, and one end of the contact end away from the speaker bracket 2 abuts against the airbag module 8. By matching the provided mounting end with the first mounting hole 24, assembly can be easily achieved, and the contact end can maintain a certain length to abut against the airbag module 8.

[0052] In some examples, the support portion 23 is configured as a nail structure, that is, the mounting end can be configured as a conical head, and the mounting end passes through the first mounting hole 24 to achieve clamping and fixing. The first mounting hole 24 is provided on the side of the speaker bracket 2 facing the airbag module 8 and penetrates the speaker bracket 2 along the first direction. The support portion 23 can be made of high-hardness rubber, which can avoid abnormal noise at the connection between the airbag module 8 and the support portion 23, and is also conducive to the assembly connection between the airbag module 8 and the speaker bracket 2, while maintaining the abutment effect on the airbag module 8. In other examples, the support portion 23 can also be hard plastic.

[0053] Optionally, in one embodiment of the present disclosure, a mating portion 81 is formed on one side of the airbag module 8 facing the speaker bracket 2, and the mating portion 81 is arranged opposite to the support portion 23, and the mating portion 81 and the support portion 23 abut against each other. The mating portion 81 provided can facilitate contact with the support portion 23, facilitate the mating of the two, and avoid affecting the airbag module 8. In some examples, the mating portion 81 is a convex structure formed on one side of the airbag module 8 facing the speaker bracket 2.

[0054] It should be noted that the support portion 23 and the matching portion 81 can be exchanged, that is, the support portion 23 is provided on the airbag module 8 , and the matching portion 81 is provided on the speaker bracket 2 .

[0055] Optionally, in one embodiment of the present disclosure, the number of the supporting portions 23 and the number of the matching portions 81 are both multiple and arranged at intervals. This arrangement can provide a multi-point support effect and improve the support stability between the airbag module 8 and the speaker bracket 2. In some examples, the number of the supporting portions 23 and the number of the matching portions 81 are both four and distributed at the four corners. It should be noted that the number of the supporting portions 23 and the number of the matching portions 81 can be set according to actual needs, and no excessive restrictions are imposed here.

[0056] Optionally, in one embodiment of the present disclosure, a spring steel strip 25 is provided on the speaker bracket 2, and the airbag module 8 includes an airbag housing 82 and a hook 83 formed on the airbag housing 82, and the hook 83 can be engaged with or disengaged from the spring steel strip 25. This arrangement can facilitate the assembly and connection of the airbag module 8 and the speaker bracket 2, and can also facilitate the disassembly of the airbag module 8 for replacement and other operations.

[0057] It is understandable that the spring steel strip 25 is fixed on the speaker bracket 2. During assembly, the groove of the hook 83 is stuck on the spring steel strip 25. At this time, the airbag module 8 is connected to the speaker bracket 2, and the upper support portion 23 of the speaker bracket 2 is abutted against the matching portion 81. During disassembly, the hook 83 is removed from the spring steel strip 25 to remove the airbag module 8. In some examples, there are multiple hooks 83, and the multiple hooks 83 are arranged at intervals, so that multi-point connection can be achieved, improving connection stability and connection strength.

[0058] In some examples, the spring steel bar 25 is located on the side of the speaker bracket 2 facing away from the airbag module 8, and a mounting structure is set on the side of the speaker bracket 2 facing away from the airbag module 8. The spring steel bar 25 is connected to the mounting structure. At the same time, a connecting port for the hook 83 to pass through can be opened on the speaker bracket 2, so that the hook 83 can be engaged with the spring steel bar 25 after passing through the connecting port, and the spring steel bar 25 can undergo elastic deformation within a certain range to achieve connection and detachment with the hook 83.

[0059] Optionally, in an embodiment of the present disclosure, the airbag module 8 further includes a first spring 84 , and the first spring 84 is sleeved on the hook 83 .

[0060] The airbag module 8 and the speaker bracket 2 are in a connected state. In the connected state, the hook 83 is engaged with the spring steel strip 25, and the two ends of the first spring 84 are respectively in contact with the sides of the airbag module 8 and the speaker bracket 2 facing each other, and the first spring 84 is in a compressed state. It can be understood that when the airbag module 8 and the speaker bracket 2 are connected through the hook 83 and the spring steel strip 25, the first spring 84 is always kept in a compressed state, which can improve the degree of engagement between the hook 83 and the spring steel strip 25. At the same time, when the airbag module 8 needs to be disassembled, after the hook 83 is separated from the spring steel strip 25, the first spring 84 can push the airbag module 8 to move away from the speaker bracket 2, so that the two are easily separated, which is conducive to the replacement of the airbag module 8 and other operations.

[0061] Optionally, in an embodiment of the present disclosure, the steering wheel further includes a steering wheel frame 1 , a damping mechanism and connecting bolts 5 .

[0062] A second mounting hole 21 is provided on the speaker bracket 2, a third mounting hole 11 connected to the second mounting hole 21 is provided on the steering wheel frame 1, the damping mechanism is located in the second mounting hole 21, and the connecting bolt 5 is suitable for passing through the damping mechanism and fixedly connected to the steering wheel frame 1 through the third mounting hole 11.

[0063] The damping mechanism includes an energy absorbing part and a second spring 6, the second spring 6 is sleeved on the connecting bolt 5, the two ends of the second spring 6 are respectively in contact with the steering wheel frame 1 and the energy absorbing part, and there is a gap between the horn bracket 2 and the steering wheel frame 1. The horn bracket 2 can be connected to the steering wheel frame 1 by the provided connecting bolt 5, and the connecting bolt 5 can produce a guiding effect, so that the horn bracket 2 can move in a small range along the length direction of the connecting bolt 5.

[0064] The energy absorbing part includes a damping block 3 and a sleeve 4 . The damping block 3 is sleeved in the sleeve 4 . The damping block 3 is fixed to the second mounting hole 21 . The connecting bolt 5 passes through the sleeve 4 and is threadedly connected to the third mounting hole 11 .

[0065] Among them, the second spring 6 can be compressed and rebounded, so that the speaker bracket 2 can be reset. It can be understood that when the speaker bracket 2 moves toward the steering wheel frame 1, the second spring 6 will be compressed, and then the rebound of the second spring 6 can drive the speaker bracket 2 to move away from the steering wheel frame 1 to achieve reset. Among them, the damping block 3 can produce the effect of absorbing vibration and achieve vibration reduction. In some examples, the damping block 3 is an elastomer, which can be a highly elastic rubber. When the steering wheel frame 1 is subjected to vibration from the chassis, the vibration will be transmitted to the sleeve 4 through the steering wheel frame 1 and the connecting bolt 5. The sleeve 4 will transmit the vibration energy to the damping block 3. The damping block 3 is connected to the speaker bracket 2. The speaker bracket 2 and the airbag module 8 are set as mass blocks. The damping block 3 can produce elastic deformation and absorb part of the vibration energy. The mass block can produce a counterweight effect, thereby absorbing the vibration.

[0066] In some examples, the steering wheel frame 1 is generally made of magnesium alloy and is the most important part of the steering wheel. On the one hand, it bears most of the static and dynamic loads, and on the other hand, it provides support and attachment for other components on the steering wheel. Functional components such as foam, leather, decorative parts, switches, and horn mechanisms on the steering wheel are directly or indirectly connected to the steering wheel frame 1.

[0067] Optionally, in an embodiment of the present disclosure, one end of the second spring 6 abuts against the sleeve 4 , and the sleeve 4 is provided with a limiting groove 44 for accommodating part of the second spring 6 .

[0068] The end of the sleeve 4 facing away from the airbag module 8 forms a limiting groove 44, and a part of the second spring 6 is inserted into the limiting groove 44. The limiting groove 44 can limit the random movement of the second spring 6, thereby avoiding the random movement of the second spring 6 during compression and rebound, thereby preventing abnormal noise or malfunction. In some examples, the limiting groove 44 is an annular groove, and the limiting groove 44 is formed by the concave end surface of the end of the sleeve 4 facing away from the airbag module 8.

[0069] Optionally, in one embodiment of the present disclosure, a limiting portion 45 is formed on the groove wall and / or the groove bottom of the limiting groove 44, and one end of the second spring 6 is clamped on the limiting portion 45. The limiting portion 45 may be a limiting rib, and the limiting portion 45 is used to clamp and fix one end of the second spring 6 extending into the limiting groove 44, thereby improving the limiting effect on the second spring 6. In some examples, the number of the limiting portions 45 may be multiple, and the multiple limiting portions 45 are arranged at intervals along the extension direction of the limiting groove 44.

[0070] Optionally, in one embodiment of the present disclosure, the damping mechanism further includes a buffer gasket 7, the buffer gasket 7 is configured as an annular structure, the connecting bolt 5 includes a stud 51 and a head 52, the head 52 is connected to one end of the stud 51, the buffer gasket 7 is sleeved on the stud 51, and the buffer gasket 7 is clamped between the head 52 and the damping mechanism. The buffer gasket 7 is provided to prevent the impact noise generated between the damping block 3 and the sleeve 4 and the connecting bolt 5 respectively when the airbag module 8 is pressed. In some examples, the buffer gasket 7 is made of a soft material, such as rubber. In some examples, the buffer gasket 7 is clamped between the head 52 and the damping block 3.

[0071] Optionally, in an embodiment of the present disclosure, the main body of the speaker bracket 2 is generally composed of a metal conductive plate and a plastic-coated part thereon, and the conductive plate plays a conductive role and a supporting role for the speaker.

[0072] Optionally, in one embodiment of the present disclosure, a first speaker contact 12 is provided on the steering wheel frame 1, a second speaker contact 22 is provided on the speaker bracket 2, the first speaker contact 12 and the second speaker contact 22 are arranged at a relative interval, a buffer pad buckle 13 is provided between the first speaker contact 12 and the steering wheel frame 1, and the buffer pad buckle 13 is connected to the steering wheel frame 1. Through the contact between the first speaker contact 12 and the second speaker contact 22, electrical conduction can be achieved, and the speaker can sound, and the buffer pad buckle 13 can play a buffering role, which can prevent the first speaker contact 12 and the second speaker contact 22 from generating abnormal noise when they collide.

[0073] It can be understood that when pressing the airbag module 8 drives the speaker bracket 2 to move toward the steering wheel frame 1, the second speaker contact 22 moves toward and contacts the first speaker contact 12, the speaker is electrically conductive, and the speaker makes a sound; when the airbag module 8 is released, the second spring 6 rebounds, driving the second speaker contact 22 to move away from the first speaker contact 12 and separate, and the speaker stops making a sound.

[0074] In some examples, the first speaker contact 12 and the second speaker contact 22 may be separate conductive metal blocks. To ensure contact reliability, the surfaces of the first speaker contact 12 and the second speaker contact 22 may be rust-proofed. In some examples, the first speaker contact 12 may be connected to the steering wheel frame 1 by screws, and the second speaker contact 22 may be connected to the speaker bracket 2 by riveting or welding. The speaker bracket 2 is provided with a speaker harness plug interface for achieving electrical connection. The speaker bracket 2 is provided with a fourth mounting hole, and the second speaker contact 22 may be mounted in the fourth mounting hole. Of course, the first speaker contact 12 may also be riveted to the steering wheel frame 1.

[0075] The first speaker contact 12 can be used as the negative electrode, and the second speaker contact 22 can be used as the positive electrode, or vice versa. In other examples, the second speaker contact 22 can also be a boss structure directly protruded from the conductive plate of the speaker bracket 2, and electrical conduction can also be achieved.
