[0035] Please refer to Figures 1-3 , Figure 1 is a structural schematic diagram of an embodiment of a tolerance adjustment assembly of the present application, Figure 2 is Figure 1 is a structural schematic diagram of a second view of the tolerance adjustment assembly in Figure 3 is Figure 1 is a structural schematic diagram of a third view of the tolerance adjustment assembly in the present application. The tolerance adjustment assembly 1 provided by the present application comprises a first assembly part 11, a second assembly part 12 and a fixing part 13.

[0036] The first assembly 11 is fitted onto the second assembly 12, allowing the second assembly 12 to be adjusted axially along the first assembly 11. The second assembly 12 is provided with a plurality of support members 121, which are spaced apart along the inner circumferential surface of the second assembly 12. The fixing member 13 is provided on the second assembly 12 and abuts against the support members 121. The support members 121 are used to fix the fixing member 13 and allow the fixing member 13 to be adjusted radially along the first assembly 11.

[0037] In one embodiment, the first assembly 11 can be a screw tube, the second assembly 12 can be a screw rod, and the fastener 13 can be a screw.

[0038] Specifically, the fastener 13 can be first installed on the second assembly 12, and the support 121 on the second assembly 12 can fix the fastener 13 to prevent it from falling off during assembly, thus improving stability during installation. Then, the first assembly 11 and the second assembly 12 are assembled.

[0039] In one embodiment, such as Figure 4 and Figure 5 As shown, Figure 4 This is a structural schematic diagram of an embodiment of the first assembly of this application. Figure 5 This is a schematic diagram of a structure of an embodiment of the second assembly of this application. The inner circumferential surface of the first assembly 11 has a first thread 111, and the outer circumferential surface of the second assembly 12 has a second thread 122 corresponding to the first thread 111. The first thread 111 and the second thread 122 are used to assemble the first assembly 11 and the second assembly 12. Furthermore, during the assembly process of the first assembly 11 and the second assembly 12, the second assembly 12 can be adjusted axially in the first assembly 11, thereby adjusting the installation tolerance of the two components to be installed during the installation process through the tolerance adjustment assembly 1.

[0040] Alternatively, please continue reading Figure 3 The number of support members 121 is greater than or equal to 3, and the distance between any two adjacent support members 121 is equal, thereby providing a stable force on the fixing member 13 to fix the fixing member 13.

[0041] Alternatively, please continue reading Figure 6 , Figure 6 yes Figure 1A schematic view of a cross-sectional structure of the middle-tolerance adjusting assembly along the cross-sectional line I-I'. The second assembly part 12 comprises a bottom plate 123 arranged at one end of the second assembly part 12, and a support part 121 arranged close to the bottom plate 123. The center of the bottom plate 123 is provided with a through hole 1231, and the fixing part 13 is arranged on the second assembly part 12 through the through hole 1231. The support part 121 fixes one end of the fixing part 13 in the second assembly part 12.

[0042] Specifically, as shown in Figure 6 the support part 121 comprises a first support section and a second support section connected in sequence. The first support section is away from the bottom plate 123 relative to the second support section. The distance between the first support section and the inner circumferential surface of the second assembly part 12 increases in the direction close to the bottom plate 123, and the distance between the second support section and the inner circumferential surface of the second assembly part 12 is smaller than the maximum distance between the first support section and the inner circumferential surface of the second assembly part 12.

[0043] The fixing part 13 comprises a flange plate 131. During the process of arranging the fixing part 13 on the second assembly part 12, as the flange plate 131 on the fixing part 13 moves close to the bottom plate 123, the flange plate 131 gradually abuts against the first support section. The first support section can guide the fixing part 13, and as the fixing part 13 moves, the flange plate 131 will extrude the first support section. After the fixing part 13 is moved into place, that is, when the flange plate 131 abuts against the second support section, the first support section returns to its original shape. At this time, the connection between the first support section and the second support section forms an undercut structure, which blocks the movement of the flange plate 131 away from the bottom plate 123, that is, the fixing effect of the fixing part 13 is achieved. At this time, the plurality of support parts 121 abut against the flange plate 131, and since the distance between any two adjacent support parts 121 is equal, the support parts 121 can provide uniform force on the flange plate 131 to fix the fixing part 13, avoiding the fixing part 13 from falling off the second assembly part 12.

[0044] Further, the fixing part 13 further comprises a main body handle 132, and the flange plate 131 is arranged at one end of the main body handle 132. The radial cross-sectional area of the through hole 1231 is smaller than the radial cross-sectional area of the flange plate 131, and the radial cross-sectional area of the through hole 1231 is larger than the radial cross-sectional area of the main body handle 132.

[0045] Specifically, since the radial cross-sectional area of the flange plate 131 is smaller than the radial cross-sectional area of the through hole 1231, the flange plate 131 will not be separated from the second assembly part 12 through the through hole 1231, ensuring the stability of the fixing part 13 arranged on the second assembly part 12.

[0046] The main body handle 132 can be provided with a thread for threaded connection with one of the two components to be installed. In fact, during the connection of the main body handle 132 with the component to be installed, the position of the screw hole on the component to be installed may deviate, causing the main body handle 132 to fail to be screwed into the screw hole. In the embodiment, since the radial cross-sectional area of the main body handle 132 is smaller than the radial cross-sectional area of the through hole 1231, and due to the presence of the support 121, when the position of the screw hole deviates, the main body handle 132 will automatically align with the screw hole. During this process, the main body handle 132 moves along with the position of the screw hole in a plane perpendicular to the extension direction of the main body handle 132, and the flange plate 131 also moves in the plane. The movement of the flange plate 131 extrudes the support 121, and since the number of supports 121 is greater than or equal to 3 and is uniformly distributed around the flange plate 131, different supports 121 still work together to fix the fixing member 13.

[0047] Through the cooperation of the above structure, the adjustment of the fixing member 13 in the radial direction of the first assembly member 11 during installation is realized, the automatic centering alignment of the fixing member 13 is realized, and the installation tolerance adjustment of the two components to be installed during installation is realized.

[0048] Optionally, the second assembly member 12 is also provided with a plurality of movable relief holes 124, which are arranged around the through hole 1231 and correspond to the supports 121. When the supports 121 are extruded by the flange plate 131, the deformed parts of the supports 121 can enter the movable relief holes 124 to avoid unpredictable deformation of the supports 121 caused by extrusion.

[0049] Optionally, the first thread 111 and the second thread 122 are trapezoidal threads, wherein, as shown in Figure 6 The first thread 111 and the second thread 122 can be trapezoidal threads, which solves the problem of point contact of the threads in the existing tolerance adjustment device, which is prone to stress concentration and creep attenuation. The trapezoidal threads used in the present application are more uniform in stress and better in stability. By adjusting the lead angle of the thread, the self-locking property of the thread cooperation is reduced, and thus the first thread 111 and the second thread 122 can be more easily cooperated during the process of pressing the fixing member 13 by the user, so that the first assembly member 11 and the second assembly member 12 are assembled, the installation difficulty of the tolerance adjustment assembly 1 is reduced, and the user experience of the tolerance adjustment assembly 1 is improved.

[0050] Optionally, please continue to refer to Figure 5The outer circumferential surface of the second assembly part 12 comprises a first plane 125 and a second plane 126, which are parallel to each other. By cutting the two opposite sides of the second assembly part 12, a parting line for injection molding can be reserved, so as to prevent the injection molding parting burr from causing the second thread 122 to be stuck, and thus affecting the assembly of the first assembly part 11 and the second assembly part 12.

[0051] In conclusion, the tolerance adjustment assembly 1 provided by the present application comprises a first assembly part 11, a second assembly part 12 and a fixing part 13. Through the cooperation of the first assembly part 11, the second assembly part 12 and the fixing part 13, the adjustment in the axial and radial directions of the first assembly part 11 can be realized, and the automatic alignment and centering of the fixing part 13 are allowed, so as to realize the tolerance adjustment of the to-be-installed components in the axial and radial directions, and the structure is simple, the assembly is convenient, the cost is economic, and the use experience of the user for the tolerance adjustment assembly 1 can be effectively improved.

[0052] The present application also provides a vehicle (not shown in the figure), which comprises the tolerance adjustment assembly 1 as described above, and the tolerance adjustment assembly 1 is arranged between two to-be-installed components of the vehicle, so as to adjust the installation tolerance between the two to-be-installed components, and improve the installation precision of the to-be-installed components.

[0053] The above description is only the implementation of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation obtained by using the content of the specification and the drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
