[0037] The specific embodiments of the present disclosure will be described below in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0038] In the present disclosure, "inner, outer" refers to the inner and outer of the relevant parts unless otherwise stated. In addition, the terms "first", "second", and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0039] In the description of the present disclosure, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0040] With the popularity of electric vehicles, people's requirements for driving sound and body comfort are getting higher and higher. At present, the steering wheel of many vehicles will produce vibration or abnormal sound in a certain speed range (such as above 120km / h) or special road conditions (such as bumpy road conditions), and these vibrations or abnormal sounds are particularly prominent in electric vehicles. Disturbance to the driver. Among them, these vibrations are caused by the rigid connection (such as fixed by nut) of the steering wheel and the steering column, and the vibration of the steering column to the chassis is caused by the vibration of the steering column to the steering wheel. The abnormal sound is mostly caused by the vibration of the airbag module and the spring steel strip or the steering wheel skeleton that fixes the airbag module. In order to weaken these vibrations and abnormal sounds, a corresponding damping device is arranged on the steering wheel, which is generally composed of an elastomer and a mass block, and the larger the mass block, the more obvious the damping effect. At present, the mainstream is to arrange the airbag module of the steering wheel as a damping mass block.

[0041] The airbag module of the steering wheel of the related art is in relative motion with the horn bracket, that is, the airbag module and the horn bracket are not fixed relative to each other, so that when the airbag module is pressed, the airbag module and the horn bracket may be in contact, causing abnormal sound and affecting the driving comfort.

In addition, the relative fixation of the airbag module 8 and the horn bracket 2 can avoid the airbag module 8 and the horn bracket 2 from touching each other when the airbag module 8 is pressed, so as to avoid abnormal noise and improve the comfort of driving and riding.

[0045] Alternatively, in an embodiment of the present disclosure, one of the airbag module 8 and the horn bracket 2 is provided with a support portion 23 extending towards the other one of the airbag module 8 and the horn bracket 2 and abutting against the other one. The support portion 23 can extend and connect the airbag module 8 and the horn bracket 2, so that the airbag module 8 and the horn bracket 2 can not be tightly attached but still can support each other, that is, the support portion 23 can support the airbag module 8 and the horn bracket 2 when there is a gap between the airbag module 8 and the horn bracket 2, and the airbag module 8 and the horn bracket 2 can still be relatively fixed, so that the assembly operation can be facilitated.

[0046] Of course, in other embodiments, the sides of the airbag module 8 and the horn bracket 2 facing each other can be partially attached to each other to support each other.

In other examples, the support portion 23 can also be hard plastic.

[0049] Optionally, in an embodiment of the present disclosure, the side of the airbag module 8 facing the horn support 2 is formed with a matching portion 81, the matching portion 81 is arranged opposite to the support portion 23, and the matching portion 81 and the support portion 23 abut each other. The matching portion 81 can facilitate contact with the support portion 23, facilitate cooperation between the two, and avoid affecting the airbag module 8. In some examples, the matching portion 81 is a protruding structure formed on the side of the airbag module 8 facing the horn support 2.

[0050] It should be noted that the support portion 23 and the matching portion 81 can be exchanged, that is, the support portion 23 is arranged on the airbag module 8, and the matching portion 81 is arranged on the horn support 2.

[0053] It can be understood that the spring steel strip 25 is fixed on the horn support 2, and when assembling, the groove of the hook 83 is clamped on the spring steel strip 25, at this time the airbag module 8 is connected to the horn support 2, and the abovementioned horn support 2 upper support part 23 is in abutment with the matching part 81. When disassembling, the hook 83 is detached from the spring steel strip 25, and the airbag module 8 can be removed. In some examples, the number of hooks 83 is multiple, and the multiple hooks 83 are arranged at intervals, so that multi-point connection can be achieved, and the connection stability and connection strength are improved.

[0054] In some examples, the spring steel strip 25 is located on the side of the horn support 2 away from the airbag module 8, the side of the horn support 2 away from the airbag module 8 is provided with a mounting structure, the spring steel strip 25 is connected to the mounting structure, and the horn support 2 can be provided with a connecting opening through which the hook 83 passes, so that the hook 83 passes through the connecting opening and is clamped with the spring steel strip 25, and the spring steel strip 25 can be elastically deformed within a certain range to realize connection and disconnection with the hook 83.

[0055] Optionally, in an embodiment of the present disclosure, the airbag module 8 further comprises a first spring 84, and the first spring 84 is sleeved on the hook 83.

[0061] The second spring 6 can be compressed and rebounded, so that the horn support 2 can be reset. It can be understood that when the horn support 2 moves towards the steering wheel framework 1, the second spring 6 will be compressed, and then the second spring 6 will rebound to drive the horn support 2 to move away from the steering wheel framework 1 to achieve reset. The damping block 3 can absorb vibration to achieve vibration reduction. In some examples, the damping block 3 is an elastomer, which can be high-elasticity rubber. When the steering wheel framework 1 is subjected to vibration from the chassis, the vibration will be transmitted to the sleeve 4 through the steering wheel framework 1 and the connecting bolt 5, and the sleeve 4 will transmit the vibration energy to the damping block 3. The damping block 3 is connected to the horn support 2, the horn support 2 and the airbag module 8 are provided as a mass block, the damping block 3 can be elastically deformed to absorb part of the vibration energy, and the mass block can produce a counterweight effect, thereby absorbing the vibration.

[0062] In some examples, the steering wheel framework 1 is generally made of magnesium alloy, which is the most important part of the steering wheel 300. 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 300. The functional components on the steering wheel 300, such as foams, leathers, decorative parts, switches, and horn mechanisms, are directly or indirectly connected to the steering wheel framework 1.

The limiting groove 44 can limit the random movement of the second spring 6, avoiding the problem of abnormal noise or function caused by the random movement of the second spring 6 during compression and rebound. In some examples, the limiting groove 44 is an annular groove, which is formed by the concave end face of the end of the sleeve 4 away from the airbag module 8.

[0065] Optionally, in an embodiment of the present disclosure, the groove wall and / or groove bottom of the limiting groove 44 forms a limiting portion 45, and one end of the second spring 6 is clamped to the limiting portion 45. The limiting portion 45 can be a limiting rib. The second spring 6 is clamped and fixed at one end extending into the limiting groove 44 through the limiting portion 45, so that the limiting effect on the second spring 6 can be improved.
