[0032] The utility model relates to a steering wheel test auxiliary tool 10, which comprises a cover body 1 and a wear-resistant part 2, wherein the cover body 1 is used to be installed at the horn of the steering wheel, and the wear-resistant part 2 is connected to the top surface of the cover body 1 and aligned with the switch contact of the horn.

[0033] In the prior art, when testing the horn pressing force and pressing durability test of the steering wheel, the spherical pressing head directly presses the cover of the driver airbag module of the steering wheel and presses to the position of the switch contact. The switch contact contacts the closed circuit to form a loop to realize the horn pressing function. When performing the pressing durability test, the spherical pressing head acts on the driver airbag module cover for a long time, causing irreversible deformation of the driver airbag module cover, making it difficult to ensure the smooth completion of the test.

[0034] The steering wheel test auxiliary tool 10 designed by the utility model is shaped according to the surface shape of the driver's airbag module cover, and the shape of its cover body 1 can perfectly fit the cover of the driver's airbag module. Before the test begins, the cover body 1 of the steering wheel test auxiliary tool 10 can be installed on the top surface of the cover of the driver's airbag module, and the wear-resistant part 2 can be directly pressed by the spherical pressure head for testing. Since the wear-resistant part 2 has a certain wear resistance, it can not only protect the cover from damage, but also ensure the smooth completion of the test.

[0035] Preferably, the top surface of the cover body 1 is provided with an installation groove, and the wear-resistant part 2 is located in the installation groove and fixedly connected to the inner wall of the installation groove. The installation groove can limit the position of the wear-resistant part 2, enhance the stability of the wear-resistant part 2, and prevent the wear-resistant part 2 from being found to be offset during the test process.

[0036] Furthermore, a mounting post 3 is provided on the top surface of the cover body 1 , the mounting post 3 protrudes from the top surface of the cover body 1 and is aligned with the switch contact in the vertical direction. The mounting groove is formed by the top surface of the mounting post 3 being recessed.

[0037] The mounting column 3 can increase the thickness of the cover body 1 , and setting the mounting groove on the top surface of the mounting column 3 can increase the depth of the mounting groove, increase the stability of the wear-resistant part 2 , and further increase the durability of the steering wheel test auxiliary tool 10 .

[0038] Optionally, three mounting posts 3 are arranged at intervals and their top surfaces are flush, and a mounting groove is provided on the top surface of each mounting post 3, and a wear-resistant part 2 is disposed in each mounting groove, and the three wear-resistant parts 2 are aligned with three switch contacts respectively. It should be understood that the number of wear-resistant parts 2 is adapted according to the number of switch contacts, and the utility model does not limit the specific number of wear-resistant parts 2.

[0039] Each mounting groove is provided with a colloid, and each wear-resistant part 2 is connected to the inner wall of the mounting groove through the colloid. It should be understood that in other embodiments, each wear-resistant part 2 can also be connected to the inner wall of the mounting groove in other ways, and the utility model does not limit the specific way in which the wear-resistant part 2 is connected to the inner wall of the mounting groove.

[0040] Optionally, the cover 1 is made of plastic and is provided with a hollow area 4, which is located in the space formed by the three mounting posts 3 to reduce the weight of the cover 1. The total weight of the cover 1, the mounting posts 3 and the wear-resistant part 2 is controlled between 95g and 105g.

[0041] The bottom of the wear-resistant part 2 is connected to the inner wall of the mounting groove, and the top protrudes from the top surface of the mounting column 3. The top of the wear-resistant part 2 is an arc surface protruding upward, and can be an arc surface of any arc. When the columnar pressure head presses the top surface of the wear-resistant part 2, it is closer to imitating the process of a human body pressing a steering wheel.

[0042] Furthermore, the wear-resistant part 2 is a steel ball or a sphere of other metals. In other embodiments, the wear-resistant part 2 can also be a sphere of other materials, such as ceramic or other alloys, etc., as long as it has a certain wear resistance, and the specific material of the wear-resistant part 2 is not limited.

[0043] The diameter of the spherical wear-resistant part 2 is preferably between 8 mm and 10 mm, and the total height of the wear-resistant part 2 after being installed on the mounting column 3 is less than 20 mm. In other words, after the mounting column 3 and the wear-resistant part 2 are assembled, the height of the entire protrusion from the top surface of the cover body 1 is less than 20 mm, which can not only ensure the stability and durability of the wear-resistant agent, but also will not affect the sensitivity of the test.

[0044] The utility model also relates to a steering wheel durability testing device, which comprises a servo motor, a pressure head and the above-mentioned steering wheel test auxiliary tool 10, wherein the pressure head is a column, the servo motor is connected to the pressure head and can drive the pressure head to move up and down, and continuously press the wear-resistant part 2 as required.

[0045] The pressure head of the conventional steering wheel durability test device is spherical, which directly presses the steering wheel cover and easily damages the cover. The steering wheel durability test device of the utility model is a column, which can match the spherical wear-resistant part 2 of the steering wheel test auxiliary tool 10. The pressure head of the column matches the spherical wear-resistant part 2, which can not only protect the cover from damage, but also ensure the test sensitivity.

[0046] Preferred embodiments of the present invention have been described in detail above, but it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide further embodiments.
