Automobile performance detection is a comprehensive and meticulous process, involving multiple aspects such as vehicle safety, reliability, power performance, economy, and noise and exhaust emissions. Through scientific and standardized detection methods, problems existing in the vehicle can be discovered and solved in a timely manner to ensure the safe and reliable operation of the vehicle.

[0003] Currently, during vehicle vibration testing and modal testing, vibration data of the steering wheel needs to be collected under some working conditions. When specifically measuring the vibration of the steering wheel in relevant tests, an acceleration sensor needs to be fixed to the steering wheel.

[0023] To make the purpose, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the specific embodiments of the present utility model. Obviously, the embodiments described below are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this patent.

[0024] Embodiment 1, referring to the attached Figure 1 and 2, the description is as follows: A sensor mounting mechanism of the present utility model includes two arc-shaped clamping plates 1. One end of the two arc-shaped clamping plates 1 is hinged to each other, and the other end of the two arc-shaped clamping plates 1 is detachably connected through a quick-installation component, so that the two arc-shaped clamping plates 1 form an annular fixture that can be opened and closed and can clamp the steering wheel; a regular hexagon-shaped fixing slot 2 is opened at the center position of one of the arc-shaped clamping plates 1, and an NFC module is embedded in this arc-shaped clamping plate 1. A GPS module 3 can be inserted into the inside of the fixing slot 2; a tabletop is provided at the center position of the other arc-shaped clamping plate 1 for placing the sensor, and its sensor model is: TLD356A16.

[0025] Professional personnel are generally equipped with a suitable special test module, so when professional personnel use it, there is no need to use the mobile phone holder 9. The operation is as follows: Open the two arc-shaped clamping plates 1, and then clamp the two arc-shaped clamping plates 1 on the steering wheel through the quick-installation component, that is, make the annular fixture clamp the steering wheel. The two arc-shaped clamping plates 1 adopt an openable and detachable connection structure. Through this design, the applicable range of this mounting mechanism is effectively increased, so that it can adapt to steering wheels or cylindrical parts of various sizes. After the arc-shaped clamping plates 1 are clamped, the sensor is installed on the tabletop. When the arc-shaped clamping plate 1 is made of metal, the sensor can be adsorbed on the tabletop by magnetic attraction. When the arc-shaped clamping plate 1 is made of non-metal material, the sensor can be fixed on the tabletop by bonding. After the sensor is installed, relevant tests can be carried out. At the same time, during the process of dynamically testing and collecting vehicle speed data, the GPS module 3 can also be installed through the fixing slot 2, so as to achieve synchronous collection of vibration data and vehicle speed data.

[0026] Specifically, the quick-installation component includes a threaded rod 4 and a fixing nut 6. One end of one of the arc-shaped clamping plates 1 is provided with a threaded rod 4, and the end of the other arc-shaped clamping plate 1 is provided with a connection opening 5 corresponding to the threaded rod 4. When the threaded rod 4 is placed inside the connection opening 5, the fixing nut 6 is screwed with the threaded rod 4 to lock the two arc-shaped clamping plates 1. The design of the above quick-installation component is relatively reasonable, which is convenient for assembly and use and can reduce the assembly cost.

[0027] Specifically, a limiting groove is opened on the inner side wall of the fixing slot 2, and a limiting block 10 corresponding to the limiting groove is provided on the outer side wall of the GPS module 3. The limiting block 10 is inserted into the limiting groove. Through this design of the limiting block 10 and the limiting groove, the friction force between the GPS module 3 and the fixing slot 2 can be further increased, so as to prevent the GPS module 3 from falling off.

[0028] Specifically, a regular hexagon-shaped bit slot 7 is opened at the center position of the tabletop, and this bit slot 7 can be adapted to a 6.35 mm screwdriver bit.

[0029] Specifically, anti-slip ridges 8 are provided on the inner side of the arc-shaped clamping plate 1.

[0030] Specifically, a wire clamping groove 102 is formed in the arc-shaped clamping plate 1. The cables of the sensors and modules can be clamped into the wire clamping groove 102, thereby improving the aesthetics. Moreover, the design of the wire clamping groove 102 can also reduce the weight of this installation mechanism.

[0031] Specifically, a counterweight hole 101 is formed in the arc-shaped clamping plate 1.

[0032] Embodiment 2, referring to the attached Figure 1 and 2 , the description is as follows: On the basis of the embodiment, a mobile phone holder 9 can be inserted through the fixed slot 2. The mobile phone holder 9 includes a support plate 901. The top side of the support plate 901 is used to place the mobile phone. A plug-in block 902 corresponding to the fixed slot 2 is fixed at the center position of the bottom side of the support plate 901. The support plate 901 is inserted into the fixed slot 2 through the plug-in block 902. A baffle 906 capable of blocking the mobile phone is provided at one end of the support plate 901, and a limiting component capable of resisting the mobile phone is provided at the other end of the support plate 901.

[0033] It is generally difficult for non-professionals to be equipped with a dedicated test module that is well-matched. Therefore, when non-professionals use it, the mobile phone holder 9 can be installed through the fixed slot 2, and then the mobile phone can be installed on the mobile phone holder 9. The operation is as follows: After the mobile phone holder 9 is installed, place the mobile phone on the top side of the support plate 901. At this time, one side of the mobile phone is closely against the baffle 906. The baffle 906 can be an arc-shaped plate, and the arc-shaped plate can better clamp the side of the mobile phone. Then, the mobile phone can be fixed through the limiting component. The mobile phone can jump to the adapted website through the inductive NFC module to obtain the vibration software, as well as information such as the use, download guide, prior help, and problem feedback of the software. After the mobile phone is debugged, a preliminary vibration test can be carried out.

[0034] Specifically, the limiting component includes a fixing plate 903 and a limiting bolt 904. The fixing plate 903 is fixed at the end of the support plate 901. The limiting bolt 904 is screwed to the fixing plate 903 and penetrates through the fixing plate 903. A pressing plate 905 for resisting the mobile phone is connected to the bolt rod of the limiting bolt 904. By rotating the limiting bolt 904, the pressing plate 905 can move forward or backward, so that the pressing plate 905 can resist or move away from the side of the mobile phone. The pressing plate 905 can be made of a rubber plate, and the rubber plate can better protect the outer surface of the mobile phone.

[0035] Specifically, a limiting block 10 corresponding to the limiting groove is provided on the outer side wall of the plug-in block 902. The limiting block 10 is inserted into the limiting groove. Through this design of the limiting block 10 and the limiting groove, the friction force between the plug-in block 902 and the fixed slot 2 can be further increased, thereby preventing the mobile phone holder 9 from falling off.
