Figure 3 yes Figure 1 A structural schematic diagram of the tolerance adjustment assembly from a third-view perspective. The tolerance adjustment assembly 1 provided in this application embodiment includes an adjustment screw tube 11, an adjustment screw rod 12, a bolt 13, and a bolt fastener 14.

[0037] The adjusting screw tube 11 is sleeved on the adjusting screw rod 12, and is used to allow the adjusting screw rod 12 to be adjusted in the axial direction of the adjusting screw tube 11. The adjusting screw rod 12 has a containing space 121, and a plurality of supporting members 122 are arranged on the adjusting screw rod 12 and are arranged in the containing space 121 in a spaced manner. The bolt 13 is arranged on the adjusting screw rod 12, and the bolt fixing member 14 is arranged in the containing space 121. Further, the bolt fixing member 14 is in abutment with the bolt 13, and is used to fix the bolt 13. The plurality of supporting members 122 are in abutment with the bolt 13 respectively, and are used to allow the bolt 13 to be adjusted in the radial direction of the adjusting screw tube 11.

[0038] Specifically, since the bolt 13 is arranged on the adjusting screw rod 12, the adjusting screw rod 12 is adjusted in the axial direction of the adjusting screw tube 11, and the bolt 13 can be adjusted in the axial direction of the adjusting screw tube 11. Since the supporting members 122 are arranged on the adjusting screw rod 12, the bolt 13 can be adjusted in the radial direction of the adjusting screw tube 11, that is, the axial and radial adjustments can be realized by the adjusting screw tube 11, the adjusting screw rod 12 and the bolt 13. The structure is simple, the assembly is convenient, the two components to be installed can be adjusted in the mounting tolerance by the tolerance adjusting assembly 1, the installation precision is improved, and the user experience of the tolerance adjusting assembly 1 is improved.

[0039] In an embodiment, please refer to Figure 4 and Figure 5 , Figure 4 is a structural schematic view of an embodiment of the adjusting screw tube of the present application, Figure 5 is a structural schematic view of an embodiment of the adjusting screw rod of the present application. The inner circumferential surface of the adjusting screw tube 11 is provided with threads, and the outer circumferential surface of the adjusting screw rod 12 is also provided with threads. The adjusting screw tube 11 and the adjusting screw rod 12 are assembled by cooperation of the threads.

[0040] Optionally, please refer to Figure 2 and Figure 6 , Figure 6 is a structural schematic view of an embodiment of the bolt fixing member of the present application. The adjusting screw rod 12 is further provided with a plurality of sliding grooves 123, the extending direction of the sliding grooves 123 is parallel to the axial direction of the adjusting screw rod 12, the outer circumferential surface of the bolt fixing member 14 is provided with a plurality of sliding blocks 141, the sliding blocks 141 are arranged in the sliding grooves 123, and the sliding blocks 141 are used to slide in the sliding grooves 123 to guide the movement of the bolt fixing member 14.

[0041] Specifically, as shown in the drawings, during the process that the bolt fixing piece 14 enters the accommodation space 121, the sliding block 141 can first enter the sliding groove 123, and then the movement of the sliding block 141 in the sliding groove 123 can limit the bolt fixing piece 14 from moving into the accommodation space 121 along a direction parallel to the axial direction of the adjusting screw 12, because the extension direction of the sliding groove 123 is parallel to the axial direction of the adjusting screw 12. When the bolt fixing piece 14 abuts against the bolt 13, the bolt fixing piece 14 can fix the bolt 13, avoid the bolt 13 from falling off the adjusting screw 12, improve the convenience of assembling the bolt fixing piece 14 and the adjusting screw 12, simplify the assembly steps of the bolt fixing piece 14, and improve the user experience of the tolerance adjusting assembly 1.

[0042] Optionally, the adjusting screw 12 further comprises a guide undercut 124 arranged near the end of the sliding groove 123, the guide undercut 124 is provided with a first guide plane, and the first guide plane has an acute angle relationship with the central axis of the adjusting screw 12. The sliding block 141 is provided with a second guide plane, and the second guide plane has an obtuse angle relationship with the central axis of the bolt fixing piece 14. The guide undercut 124 is used to fix the bolt fixing piece 14 when the bolt fixing piece 14 abuts against the bolt 13.

[0043] Specifically, please refer to Figure 2 , Figure 6 and Figure 7 , Figure 7 is Figure 1 a cross-sectional structure diagram of the tolerance adjusting assembly along the cross-sectional line I-I’ in . When the sliding block 141 moves to contact the guide undercut 124, because the first guide plane has an acute angle relationship with the central axis of the adjusting screw 12, and the second guide plane has an obtuse angle relationship with the central axis of the bolt fixing piece 14, the first guide plane and the second guide plane are in contact. In an embodiment, the first guide plane and the second guide plane can be parallel at this time, the first guide plane guides the second guide plane to move the sliding block 141, and when the bolt fixing piece 14 moves to abut against the bolt 13, the sliding block 141 moves to the side away from the sliding groove 123, and is clamped by the guide undercut 124. The guide undercut 124 fixes the bolt fixing piece 14, avoids the movement of the bolt fixing piece 14 away from the bolt 13, and fixes the bolt 13 by the bolt fixing piece 14.

[0044] In other embodiments, the guide undercut 124 can also be arranged at other positions, and the application does not limit the number and arrangement position of the guide undercut 124 on the basis of realizing the fixing effect of the guide undercut 124 on the bolt fixing piece 14.

[0045] Optionally, one end of the adjusting screw 12 is also provided with an assembly gap 125, the assembly gap 125 is connected with the sliding groove 123, and the width of the assembly gap 125 decreases in the direction close to the sliding groove 123, and the minimum width of the assembly gap 125 is equal to the width of the sliding groove 123. The assembly gap 125 is used to guide the sliding block 141 into the sliding groove 123.

[0046] Specifically, since the width of the assembly gap 125 decreases in the direction close to the sliding groove 123, and the minimum width of the assembly gap 125 is equal to the width of the sliding groove 123, the sliding block 141 can easily enter the assembly gap 125, and during movement, it will be guided into the sliding groove 123 due to the assembly gap 125, reducing the difficulty of setting the sliding block 141 in the sliding groove 123, and improving the user experience of the tolerance adjusting assembly 1.

[0047] Optionally, as shown in Figure 6 , the bolt fixing piece 14 is also provided with a plurality of avoiding grooves 142, the avoiding grooves 142 correspond to the supporting pieces 122, specifically, the number and setting position of the avoiding grooves 142 correspond to the supporting pieces 122, and then when the bolt fixing piece 14 and the bolt 13 are in abutment and the bolt 13 is fixed, the supporting pieces 122 are located in the avoiding grooves 142, avoiding the bolt fixing piece 14 extruding the supporting pieces 122, so that the supporting pieces 122 are extruded and deformed, affecting the adjustment of the bolt 13 in the radial direction through the supporting pieces 122.

[0048] Optionally, the bolt 13 includes a bolt flange plate 131, and the bolt fixing piece 14 includes a fixed bottom plate 143, the fixed bottom plate 143 is in abutment with the bolt flange plate 131 to fix the bolt 13.

[0049] Among them, as shown in Figure 2 or Figure 7 , the abutment of the bolt fixing piece 14 and the bolt 13 is actually the abutment of the fixed bottom plate 143 and the bolt flange plate 131, and the fixed bottom plate 143 can be provided with a through hole, the radial cross-sectional area of the through hole is smaller than the radial cross-sectional area of the bolt flange plate 131, and then the end of the bolt 13 can be allowed to pass through and abut against the bolt flange plate 131, and the bolt 13 is fixed.

[0050] Further, the number of supporting pieces 122 is greater than or equal to 3, and the distance between any two adjacent supporting pieces 122 is equal, and the plurality of supporting pieces 122 are in abutment with the bolt flange plate 131 to allow the bolt 13 to adjust in the radial direction of the adjusting screw pipe 11.

[0051] Specifically, as shown in Figure 3 and Figure 7As shown, the plurality of support members 122 are arranged around the bolt flange plate 131, and then respectively abut the bolt flange plate 131. During the process of connecting the bolt 13 with the to-be-installed component, the bolt 13 may not be able to be screwed into the bolt hole due to the deviation of the position of the bolt hole on the to-be-installed component. In the embodiment, when the position of the bolt hole deviates, the bolt 13 will automatically align with the bolt hole. During this process, the bolt 13 will move along with the position of the bolt hole in the plane perpendicular to the extension direction of the bolt 13 (i.e., the plane direction of the bolt flange plate 131, or the radial direction of the adjusting screw tube 11), and drive the bolt flange plate 131 to move. The movement of the bolt flange plate 131 will extrude the support members 122. Since the number of the support members 122 is greater than or equal to 3 and is uniformly distributed around the bolt flange plate 131, different support members 122 still jointly abut the bolt flange plate 131.

[0052] Through the cooperation of the above structure, the adjustment of the bolt 13 in the radial direction of the adjusting screw tube 11 during the installation process is realized, the automatic centering alignment of the bolt 13 is realized, and the installation tolerance adjustment of the two to-be-installed components during the installation process of the tolerance adjustment assembly 1 is realized.

[0053] In an embodiment, the position of the adjusting screw corresponding to the arrangement position of the support member 122 can also be provided with a movable hole. The movable hole can be used to accommodate the deformed part of the support member 122 when the support member 122 is extruded and deformed.

[0054] In an embodiment, the support member 122 includes a first support segment and a second support segment connected in sequence, and the first support segment is closer to the sliding groove 123 than the second support segment. The distance between the first support segment and the inner circumferential surface of the adjusting screw 12 increases in the direction away from the sliding groove 123, and the distance between the second support segment and the inner circumferential surface of the adjusting screw 12 is equal to the maximum distance between the first support segment and the inner circumferential surface of the adjusting screw 12.

[0055] Further, when the bolt 13 is arranged on the adjusting screw 12, the bolt flange plate 131 can abut the second support segment. Since the distance between the first support segment and the inner circumferential surface of the adjusting screw 12 increases in the direction away from the sliding groove 123, the bolt flange plate 131 will not contact the first support segment before the bolt flange plate 131 moves to abut the second support segment. This reduces the friction provided by the first support segment for the movement of the bolt flange plate 131, improves the efficiency of the movement of the bolt 13, and at the same time, the design that the distance between the first support segment and the inner circumferential surface of the adjusting screw 12 increases in the direction away from the sliding groove 123 is also more beautiful, and improves the user experience of the tolerance adjustment assembly 1.

[0056] Optionally, as Figure 4As shown, at least one fixing boss 111 is arranged on the inner circumferential surface of the adjusting sleeve 11, and the fixing boss 111 is arranged at the end of the adjusting sleeve 11 to fix the adjusting screw 12 sleeved on the adjusting sleeve 11, so that the adjusting screw 12 cannot move relative to the adjusting sleeve 11 after the adjusting sleeve 11 and the adjusting screw 12 are assembled, and the assembly accuracy is affected, and the stability of the tolerance adjustment assembly 1 is improved.

[0057] Optionally, as shown, Figure 5 As shown, the outer circumferential surface of the adjusting screw 12 can be cut on both sides, and the injection molding parting line can be reserved by cutting the opposite sides of the adjusting screw 12, so that the injection molding parting burr does not cause the thread on the adjusting screw 12 to be stuck, and the assembly of the adjusting sleeve 11 and the adjusting screw 12 is affected.

[0058] Optionally, as shown, Figure 7 As shown, the threads on the adjusting sleeve 11 and the threads on the adjusting screw 12 are trapezoidal threads, which can solve the problem of thread point contact in the existing tolerance adjuster, which is prone to stress concentration and creep attenuation. In the present embodiment, the trapezoidal thread is more uniform in stress and better in stability. By adjusting the lead angle of the thread, the self-locking property of the thread fit is reduced, and in the process of pressing the bolt 13 by the user to drive the adjusting screw 12 to assemble with the adjusting sleeve 11, the adjusting sleeve 11 and the adjusting screw 12 can be more easily fitted, so that the adjusting sleeve 11 and the adjusting screw 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.

[0059] In summary, the tolerance adjustment assembly 1 provided by the present application comprises an adjusting sleeve 11, an adjusting screw 12, a bolt 13 and a bolt fixing member 14. The cooperation of the adjusting sleeve 11, the adjusting screw 12, the bolt 13 and the bolt fixing member 14 can realize adjustment in the axial and radial directions of the adjusting sleeve 11, fix the bolt 13, and allow the automatic alignment and centering of the bolt 13, 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 economical, and the user experience of the tolerance adjustment assembly 1 can be effectively improved.
