[0041] like Figures 1 to 5 As shown, a sub-frame posture adjustment device 100 provided in an embodiment of the present application is used to adjust the installation position between a vehicle body 200 and a sub-frame 300, wherein a wheel 301 is mounted on the sub-frame 300; the sub-frame posture adjustment device 100 comprises a base 10, a stand 20 and a sensor assembly 30, wherein the base 10 is used to carry the wheel 301; the stand 20 is movably mounted on the base 10, the stand 20 can be abutted against the sub-frame 300, and the stand 20 can drive the sub-frame 300 to vibrate relative to the vehicle body 200; the sensor assembly 30 is mounted on the base 10, and the sensor assembly 30 is used to obtain the posture of the sub-frame 300 and generate a feedback signal, and use this as a judgment standard for adjusting the installation position between the vehicle body 200 and the sub-frame 300.

[0042] It can be understood that the posture of the subframe 300 after being driven to vibrate by the stand 20 is obtained by the sensor assembly 30 to adjust the installation position between the vehicle body 200 and the subframe 300. In this process, the assembly stress between the subframe 300 and the vehicle body 200 can be released, so that the installation position between the vehicle body 200 and the subframe 300 can be adjusted to improve the accuracy of the relative position between the vehicle body 200 and the subframe 300.

[0043] like Figure 2As shown, in one embodiment, the sub-frame posture adjustment device 100 further includes a driving assembly 40, which is in transmission connection with the platform 20, and the platform 20 can move under the drive of the driving assembly 40 to drive the sub-frame 300 to vibrate relative to the vehicle body 200. In other words, the driving assembly 40 is used to control the movement of the platform 20, so that the movement control of the platform 20 can be automated, so as to adjust the installation position between the vehicle body 200 and the sub-frame 300. Here, the driving assembly 40 is set as a hydraulic electromechanical mechanism.

[0044] like Figure 2 As shown, in one embodiment, the driving assembly 40 includes a lifting driving member 41 and a vibration driving member 42.

In other words, the receiving groove 101 on the base 10 is used to receive the driving assembly 40 and the stand 20, so that the driving assembly 40 and the stand 20 can be easily assembled and applied on the base 10.

[0046] like Figure 3 , Figure 5 As shown, in one embodiment, a wheel positioning groove 102 is formed on the base 10 , and the wheel positioning groove 102 is arranged corresponding to the wheel 301 , and the wheel positioning groove 102 is used to limit the position of the wheel 301 .

[0047] like Figure 1 As shown, in one embodiment, a positioning member 21 is provided on the platform 20. When the platform 20 is in contact with the sub-frame 300, the positioning member 21 can be plugged and matched with the positioning hole 201 on the body 200 to position the body 200. In other words, the assembly positioning of the body 200 on the platform 20 can be achieved by plugging and matching between the positioning member 21 and the body 200, so that the subsequent use requirement of the platform 20 to adjust the installation position between the sub-frame 300 and the body 200 when the sub-frame 300 is driven to vibrate can be met. Here, the positioning member 21 can be set as a positioning pin. In this embodiment, the number of the positioning members 21 is set to four. Of course, for those skilled in the art, the number of the positioning members 21 is not limited to four, and the number of the positioning members 21 can also be set to three, five, etc. The specific number can be set according to the actual use requirements, which will not be elaborated here.

[0048] like Figure 2 , Figure 5 As shown, in one embodiment, the platform 20 can be simultaneously attached to two sub-frames 300. In other words, the platform 20 can be simultaneously attached to the sub-frames 300, so that the platform 20 can simultaneously adjust the installation positions between the two sub-frames 300 and the vehicle body 200, which has the effect of improving work efficiency and relative position accuracy.

[0049] like Figure 1 , Figure 5 As shown, in one embodiment, the sensor assembly 30 includes a wheel positioning sensor 31, which is arranged corresponding to the wheel 301 and can detect the position of the corresponding wheel 301. In other words, the posture of the subframe 300 is obtained by detecting the position of the wheel 301 by the wheel positioning sensor 31, so that the sensor assembly 30 can be made of local materials, which has the effect of reducing costs. Here, the wheel positioning sensor 31 is set as an optical camera.

[0050] like Figure 1 As shown, in one embodiment, the sensor assembly 30 further includes a bracket 32 ​​, the bracket 32 ​​is arranged corresponding to the wheel alignment sensor 31 , and the wheel alignment sensor 31 is mounted on the corresponding bracket 32 ​​; wherein the bracket 32 ​​is mounted on the base 10 .

[0051] like Figure 1 , Figure 2 As shown, in one embodiment, the subframe posture adjustment device 100 further includes a sleeve assembly 50, and the sleeve assembly 50 is used to screw the bolt 400, wherein the vehicle body 200 and the subframe 300 are connected by the bolt 400. In this embodiment, the number of the sleeve assemblies 50 is multiple.

[0052] like Figure 1 , Figure 2 As shown, in one embodiment, the sleeve assembly 50 is detachably mounted on the stand 20, and when the sleeve assembly 50 is mounted on the stand 20, the sleeve assembly 50 is disposed through the stand 20. That is, the sleeve assembly 50 that penetrates the stand 20 is used to screw the bolt 400 used to connect the sub-frame 300 and the vehicle body 200, which makes it easier to screw the bolt 400.

[0053] In summary, when the sub-frame posture adjustment device 100 of the present application is working, first, when the base 10 carries the wheel 301, the sleeve assembly 50 is used to screw the bolt 400 connecting the body 200 and the sub-frame 300 to loosen the bolt 400, and then the drive assembly 40 starts and drives the stand 20 to move, and the stand 20 drives the sub-frame 300 to vibrate relative to the body 200 to release the assembly stress between the sub-frame 300 and the body 200. In this process, the sensor assembly 30 obtains the posture of the sub-frame 300 after the vibration driven by the stand 20 and generates a feedback signal, and uses this as a judgment standard for adjusting the installation position between the body 200 and the sub-frame 300. When the sensor assembly 30 obtains that the posture of the sub-frame 300 is a preset standard posture, it means that the relative position between the body 200 and the sub-frame 300 has been accurately adjusted, and the drive assembly 40 stops driving the stand 20 to move. Finally, the sleeve assembly 50 is used to tighten the bolt 400.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
