Embodiment 1

[0040] see image 3 with Figure 4 , in this example, the steering wheel body 1 is composed of a metal frame wrapped with foam material, the airbag module 2 includes a door cover 21, an inflator 22, a housing 23 and a horn system 24, and the space between the steering wheel body 1 and the airbag module 2 is Positioning devices 3 are provided on the contact surface of the airbag module 2. The outer surface of the door cover 21 of the airbag module 2 is provided with a guide boss 211. The positioning devices 3 are distributed symmetrically with respect to the central axis. There are three positioning devices 3 in this example.

[0041] see Figure 5 , the positioning device 3 includes a mounting bracket 11 and an elastic element 12 , the mounting bracket 11 is arranged on the inner wall of the housing of the steering wheel body 1 , and the elastic element 12 is fixed on the mounting bracket 11 .

[0042] The mounting bracket 11 includes an outer frame 111 , fastening buckles 1...

Embodiment 2

[0049] The following combination Figure 12 The second embodiment of the present invention will be described, and the same components as those in the first embodiment will not be described again.

[0050] see Figure 12 , in this example, the elastic element 12 includes a support frame 121 , an elastic arm 122 , an elastic clip 123 and an arc-shaped convex surface 124 . Wherein, the elastic arm 122 is provided with a straight half-waist hole 5, which extends straight to the upper edge of the support frame 121, and one end on both sides of the elastic arm 122 is connected with the upper edge of the support frame 121. The other end of the two sides of 122 extends to the upper end of the arc-shaped convex surface 124, that is, the two sides of the elastic arm 122 jointly form an elastic structure of a cantilever beam, and the two sides of the elastic arm 122 are arranged in parallel. The two sides of the elastic arm 122 can effectively improve and adjust the elastic force of th...

Embodiment 3

[0053] The following combination Figure 13 The third embodiment of the present invention will be described, and the same components as those of the previous embodiment will not be described again.

[0054] see Figure 13 , in this example, the elastic element 12 includes a support frame 121 , an elastic arm 122 , an elastic clip 123 and an arc-shaped convex surface 124 . Wherein, the elastic arm 122 is composed of two elastic ribs 122a, the elastic ribs 122a are L-shaped, the longitudinal ends of the two elastic ribs 122a are respectively connected with the upper edge of the support frame 121, and the transverse ends of the two elastic ribs 122a extend to the arc respectively. The two sides of shaped convex surface 124. There is a certain distance between the two elastic ribs 122a of the elastic arm 122, so that the elastic arm 122 is more easily deformed, and the L-shaped elastic rib 122a structure effectively increases the distance between the two elastic ribs 122a, there...

Abstract

The invention relates to the technical field of car safety, in particular to a steering wheel with a safety air bag module positioning device. The steering wheel comprises a steering wheel body and a safety air bag module. The positioning device and a guide boss are disposed on the contact face of the steering wheel body and the safety air bag module. The position of the positioning device corresponds to the position of the guide boss. The positioning device comprises a mounting support and an elastic element. The mounting support is disposed on the inner wall of the accommodating chamber of the steering wheel body. The elastic element is fixed on the mounting support. The guide boss is mounted on the outer surface of the face plate of the safety air bag module. Compared with the prior art, the steering wheel has the advantages that by the positioning device and the guide boss disposed on the contact face of the steering wheel body and the safety air bag module, the safety air bag module can be mounted at the center of the steering wheel boy in a positioned manner; due to the fact that the elastic element of the positioning device is provided with an arc-shaped protruding face, the free moving gap of the safety air bag module in the steering wheel is eliminated.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a steering wheel provided with a safety air bag module positioning device. Background technique [0002] A common steering wheel assembly generally includes a steering wheel body and an airbag module. The center of the steering wheel body is provided with a chamber, which is the installation location of the airbag module. When the car is severely impacted, the airbag module pops up from the container and deploys to effectively protect the driver. [0003] Since the airbag module is arranged in the steering wheel body, the airbag module must be separated from the steering wheel body by at least one gap in order to obtain a specific design effect allowing the airbag module to perform the intended movement of its operation. Furthermore, the horn device of the motor vehicle is activated by manually applying pressure to the face of the airbag module. [0004] see figure ...
