Description

Technical Field

[0001] The utility model relates to the field of sensor positioning devices, in particular to a sensor positioning device used for vibration testing of automobile seats. Background Art

[0002] Car seats need to undergo a certain degree of vibration resistance testing during the assembly process and before they are shipped out of the factory. In the prior art, vibration test sensors are usually placed manually at opposite ends of the car seat, and then a vibration test is performed. However, current car seat assembly basically adopts automatic assembly line assembly, and on this basis, manpower is invested in vibration testing of the sensor, which not only slows down the assembly speed and reduces efficiency, but also increases production costs.

[0003] According to the published patent 202222087393.7, a sensor positioning device for automobile seat vibration testing includes a first mounting plate, a sensor grabbing mechanism, a second mounting plate and an adjustment assembly. The sensor grabbing mechanism is arranged at both ends of the first mounting plate, and the sensor grabbing mechanism includes a clamping claw, which can be opened and closed to clamp or release the sensor for the vibration test of the automobile seat; the second mounting plate is arranged above the first mounting plate and is movably connected with the first mounting plate; the adjustment component includes a first limiter formed on the first mounting plate and a second limiter formed on the second mounting plate, and the first limiter and the second limiter are movably connected, and the first mounting plate can change the local or overall relative height between the first mounting plate and the second mounting plate through the adjustment component. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. The adjustment component allows the first mounting plate and the second mounting plate to be adaptively adjusted, so that a certain degree of buffer is formed between the first mounting plate and the second mounting plate to solve the problem of damage to the automobile seat when installing the sensor. During use, the traditional sensor positioning device for the vibration test of the automobile seat can only position the sensor according to the same model of automobile seat during use, thereby limiting the scope of the sensor positioning device during use, so as to reduce the flexibility of the sensor positioning device during use. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: a sensor positioning device designed for automobile seat vibration testing, including a vibration test seat, a first positioning plate and a second positioning plate are connected to the middle of the vibration test seat by a fixed axis, a through groove is opened in the middle of the first positioning plate, a plug-in plate is opened in the middle of the second positioning plate, track grooves are opened on both sides of the first positioning plate and the second positioning plate, the interior of the track groove is connected to an L-shaped plate by a threaded rod, a vibration sensor is arranged on the L-shaped plate, one side of the first positioning plate and the second positioning plate are connected to a limiting bolt by a connecting plate, and one end of the first positioning plate and the second positioning plate are fixedly connected to a servo motor.

[0006] Preferably, one end of the fixed shaft is fixedly connected to the middle of the vibration test seat, and the other end of the fixed shaft is movably connected to the middle of the first positioning plate and the plug-in plate.

[0007] Preferably, the plug-in board is integrally formed with the middle of the second positioning board, the size of the plug-in board matches the size of the through slot, and the plug-in board is rotatably connected to the inside thereof.

[0008] Preferably, the bottom end of the L-shaped plate is connected to the outside of the threaded rod through a thread and is slidably connected to the inner wall of the track groove, and one end of the threaded rod is fixedly connected to the output end of the servo motor.

[0009] Preferably, one end of the connecting plate is fixedly connected to one side of the first positioning plate and the second positioning plate, and the limiting bolt is connected to the inside of the connecting plate through a thread and abuts against the surface of the vibration test seat.

[0010] Preferably, guide pillars are movably connected at the four corners of the vibration test seat, the other end of the guide pillar is fixedly connected to a mounting seat, a plurality of spring members are fixedly connected between the mounting seat and the vibration test seat, and vibration motors are also fixedly connected to both sides of the vibration test seat.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model combines a fixed shaft, a first positioning plate, a second positioning plate, a through groove, a plug-in plate, a track groove, a threaded rod, an L-shaped plate, a vibration sensor, a connecting plate, a limiting bolt and a servo motor. When the vibration sensor is positioned with four corners of a car seat, the angle between the first positioning plate and the second positioning plate is first adjusted according to the shape of the car seat. At this time, the limiting bolt is loosened from the connecting plate, and then the first positioning plate and the second positioning plate are rotated outside the fixed shaft. During this process, the plug-in plate on the second positioning plate will rotate in the through groove of the first positioning plate. After the angle between the first positioning plate and the second positioning plate is adjusted, the limiting bolt is tightened inside the connecting plate to limit the positions of the first positioning plate and the second positioning plate, so that the vibration sensor can be positioned according to car seats of different shapes.

[0013] After the positions of the first positioning plate and the second positioning plate are adjusted, the servo motor will drive the L-shaped plate to move inside the track groove through the threaded rod, so that the L-shaped plate will drive the detection end of the vibration sensor to move to the four corners of the car seat, and then the four corners of the car seat can be placed on the four vibration sensors. In this way, the position of the vibration sensor can be adjusted according to car seats of different sizes, thereby improving the flexibility of the sensor positioning device during use.
