With the development of automobile technology and the improvement of automobile performance, the requirement of consumers on the comfort of the whole automobile is higher and higher. If some parts of the vehicle vibrate or generate noise during driving, the riding experience of people in the vehicle is affected. For example, the steering gear is a system directly operated by a driver, and vibration and noise generated by the steering gear are directly transmitted to the driver through a steering wheel and air, which seriously affect the comfort of the driver. Therefore, the steering gear needs to be continuously tested and optimized in the development process of the steering gear.

The steering gear is generally arranged on a subframe of the vehicle, and the acceleration sensor is generally attached to the steering gear by an adhesive tape in the test. But because frame chassis can have sometimes to beat the circumstances such as glue can fatlute pollution, it is comparatively insecure to paste, and electric parts such as sensor drop and damage easily at the form in-process, simultaneously, also a large amount of sticky tapes are difficult for clearing up after the test. It is therefore desirable to provide an acceleration sensor harness and microphone fixture for securing the acceleration sensor harness or microphone within the chassis or cab during testing.

Adsorption structure 30 can be fixed connection in one of them side of fixing base 10, and adsorption structure 30 can be connected on fixing base 10 through modes such as colloid, joint spare. In some embodiments, the absorption structure 30 may also be an integrally formed structure with the fixing base 10, so that the connection between the fixing base 10 and the absorption structure 30 is firmer, and the fixing base 10 and the absorption structure 30 are prevented from being unstably connected and being separated from each other in the test process.

The clamping structure 20 is fixedly connected to the fixing base 10, and the fixing device 100 can clamp an electrical component through the clamping structure 20. The electrical component may be a component that is used during vehicle testing.

In some embodiments, the electrical component includes at least one of a wire and a microphone. The fixing apparatus 100 may hold a microphone, which is an energy conversion device converting a sound signal into an electric signal, near a position where noise is generated, and may amplify and collect the generated noise through the microphone, so as to find the position where noise is generated on a vehicle under test, determine whether a repair is completed where the noise is generated, and the like. The fixture 100 may also grip the wire to avoid damage from the wire rolling into the wheel or falling to the ground during testing.

Thus, the fixing device 100 can be adsorbed on the vehicle through the sucker 31, the adsorption effect is good, the installation and the disassembly are convenient, and the fixing device can be repeatedly used.

Specifically, the suction cup 31 may be fixedly connected to the fixing base 10, or the suction cup 31 may be integrally formed with the fixing base 10. The suction cup 31 may be made of a rubber material. Sucking disc 31 can set up to circular cover column structure, and sucking disc 31 can be the annular plane in the one side of fixing base 10 back to the back of the body, and then makes sucking disc 31 can laminate the vehicle chassis surface better, adsorbs more firmly.

Or the shape of the magnet 32 may be adapted to the shape of the holder 10. The magnet 32 may be disposed inside the fixing base 10 on a side close to the suction cup 31. Since the chassis of the vehicle may have dirt or oil stain, or the portion to be tested does not have a good position for the suction of the suction cup 31, the suction cup 31 is less firmly sucked, so that the fixing device 100 can be further fixed by the magnet 32.

The chassis frame of the vehicle is generally made of steel, and the fixing device 100 can be attached to the chassis of the vehicle through the magnet 32. Sucking disc 31 and magnet 32 can play the fixed effect of dual absorption, further strengthen fixing device 100's stability, avoid droing in the test procedure.

Meanwhile, the clamping structure 20 can rotate in the direction through the connection mode of the stud 41 and the nut 42, so that the fixing direction of the electrical component can be changed, and the electrical component can better perform a test function.

Referring to fig. 1 and 2, in some embodiments, the clamping structure 20 includes two oppositely disposed clamping members 21, the two clamping members 21 define a clamping space 211, the two clamping members 21 can rotate relatively to adjust the size of the clamping space 211, and the clamping space 211 is configured to clamp an electrical component.

Therefore, the two clamping pieces 21 can clamp the wire set and also can clamp electrical pieces with different diameters such as microphones, and the electrical pieces can be kept stable between the two clamping pieces 21, so that the test result is prevented from being influenced or the electrical pieces fall off to cause damage.
