The fixing member is sequentially inserted through the first through hole, the pushing member and the radial adjusting member, and is engaged with the locking member by a method not limited to threaded connection.

[0010] In some embodiments of this application, the elastic pressure member has a second mounting cavity and a second through hole communicating with the second mounting cavity. The pusher, the radial adjustment member, the locking member and the first component are all located in the second mounting cavity. The fixing member is sequentially disposed through the first through hole, the second through hole, the pusher and the radial adjustment member and is engaged with the locking member by a method not limited to threaded engagement.

[0011] In some embodiments of this application, the first elastic adjustment part is a spring-like structure, one end of which is fixedly connected to the cavity wall of the second mounting cavity, and the other end extends toward the second mounting cavity, so as to realize that the first elastic adjustment part undergoes elastic deformation along the axial direction of the first component.

[0012] In some embodiments of this application, the second elastic adjustment portion is provided by a spring sheet around the outer periphery of the radial adjustment member, so as to realize that the second elastic adjustment portion undergoes elastic deformation along the radial direction of the first component.

[0013] In some embodiments of this application, the first component has a limiting post and a limiting buckle, the base has a limiting hole adapted to the limiting post, and a limiting groove adapted to the limiting buckle.

[0014] In some embodiments of this application, the locking member has a slot on its outer periphery, and the radial adjusting member has a buckle on its inner periphery that matches the slot.

[0015] In some embodiments of this application, the fastener has a circumferentially provided limiting groove, and the radial adjusting member has a limiting rib in the inner circumferential direction that is adapted to the limiting groove.

[0016] In some embodiments of this application, the locking member includes a locking clip and a connecting post, wherein the locking clip is connected to the connecting post, and the internal thread or internal cavity is disposed within the connecting post.

[0017] In some embodiments of this application, the cavity wall of the receiving cavity is provided with a first type of thread structure, and the outer wall of the fastener is provided with a second type of thread structure that mates with the first type of thread structure.

[0018] This application also provides an assembly assembly including a first component, a second component, and a tolerance compensator as described above, wherein the tolerance compensator is disposed on the first component and is used to fasten the first component and the second component.

[0019] The embodiments of this application have the following advantages:

[0020] This application proposes a tolerance compensator for fastening a first component and a second component. The tolerance compensator includes a base, an axial adjustment assembly, and a radial adjustment component. The axial adjustment assembly includes a fixing component, a fastener, an elastic pressure component, a pushing component, and a locking component. The base has a receiving cavity, the axial adjustment assembly is disposed in the receiving cavity, the fixing component has an external thread, the locking component has an internal thread or an internal cavity hole that mates with the external thread, the fastener has a first mounting cavity and a first through hole communicating with the first mounting cavity, the elastic pressure component is located in the first mounting cavity and has a first elastic adjustment portion; the radial adjustment component is respectively sleeved on the locking component and the fixing component, and a second elastic adjustment portion abutting against the inner wall of the first component is provided along the outer circumference of the radial adjustment component; one side of the pushing component abuts against the first elastic adjustment portion, and the other side abuts against the radial adjustment component and the first component respectively; the fixing component passes through the first through hole, the pushing component, and the radial adjustment component in sequence and engages with the locking component in a manner not limited to threaded engagement.

[0021] During the assembly and fastening process of components to be assembled (such as fastening the first component to the second component) using a tolerance compensator, the fixing component is rotated clockwise or counterclockwise to engage with the locking component. During engagement, the head of the fixing component pushes the fastener relative to the base, causing the elastic pressure member in the first mounting cavity to move synchronously with the fastener. This, in turn, causes the pushing component to push the radial adjustment component and the first component to move synchronously. When the first component moves to contact the second component and generates friction, continuing to rotate the fixing component will cause the locking component to rotate synchronously. After the locking component rotates a preset angle under the action of the fixing component, the locking component is engaged. A portion of the fastener abuts against the component to be assembled, and the fastener and locking member continue to rotate in a manner not limited to threaded engagement to drive the locking member to move along its axial direction, thereby locking the first and second components. At the same time, when the locking member passes through the connecting hole of the second component, the first elastic adjustment part of the elastic pressure member can correct and compensate the entire tolerance compensator and the second component in the axial direction, and the second elastic adjustment part of the radial adjustment member can correct and compensate the entire tolerance compensator and the second component in the radial direction. Finally, the components to be assembled (the first and second components) are locked and fixed, realizing automatic compensation of the components to be assembled.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] like Figures 1 to 5 As shown, an embodiment of this application provides a tolerance compensator 100 for fastening a first component 110 and a second component 200. It is mainly used in applications requiring high precision in fastening assembly, primarily where the fastener 131 itself has dimensional and positioning errors, causing the fastened component 131 to be unable to be installed properly or to be misaligned. The tolerance compensator 100 includes a base 120, an axial adjustment assembly 130, and a radial adjustment component 140.

[0045] The base 120 has a receiving cavity 121, and the axial adjustment assembly 130 is disposed in the receiving cavity 121. It includes a fixing member 131, a fastener 132, an elastic pressing member 133, a pushing member 134, and a locking member 135. The fixing member 131 has an external thread, and the locking member 135 has an internal thread or an internal cavity hole that mates with the external thread. The fastener 132 has a first mounting cavity 1321 and a first through hole 1322 that communicates with the first mounting cavity 1321. The elastic pressing member 133 is located in the first mounting cavity 1321 and has a first elastic adjustment part 1331.

[0046] See also Figure 6 The radial adjustment member 140 is respectively sleeved on the circumference of the locking member 135 and the fixing member 131. A second elastic adjustment part 141 is provided along the outer circumference of the radial adjustment member 140. The second elastic adjustment part 141 abuts against the inner wall of the first component 110. One side of the pushing member 134 abuts against the first elastic adjustment part 1331, and the other side abuts against the radial adjustment member 140 and the first component 110 respectively. The fixing member 131 is sequentially inserted through the first through hole 1322, the pushing member 134 and the radial adjustment member 140, and is engaged with the locking member 135 in a manner not limited to threaded engagement.

[0047] The tolerance compensator 100 provided in this application embodiment, during the assembly and fastening process of components to be assembled (such as fastening the first component 110 to the second component 200) using the tolerance compensator 100, rotates the fixing member 131 clockwise or counterclockwise to screw the fixing member 131 and the locking member 135 into place. During the screwing process, the head of the fixing member 131 pushes the fastener 132 to move relative to the base 120, thereby causing the elastic pressure member 133 in the first mounting cavity 1321 to move synchronously with the fastener 132. This causes the pushing member 134 to push the radial adjustment member 140 and the first component 110 to move synchronously. When the first component 110 moves to contact the second component 200 and generates friction, continuing to rotate the fixing member 131 can drive the locking member 135 to rotate synchronously. The locking member 135, under the action of the fixing member 131... After rotating to the preset angle, a portion of the locking member 135 abuts against the component to be assembled. The fixing member 131 and the locking member 135 continue to rotate in a manner not limited to threaded engagement to drive the locking member 135 to move along its axial direction, thereby locking the first component 110 and the second component 200. At the same time, when the locking member 135 passes through the connecting hole of the second component 200, the first elastic adjustment part 1331 of the elastic pressure member 133 can perform axial correction and compensation for the entire tolerance compensator 100 and the second component 200, and the second elastic adjustment part 141 of the radial adjustment member 140 can perform radial correction and compensation for the entire tolerance compensator 100 and the second component 200. Finally, the components to be assembled (the first component 110 and the second component 200) are locked and fixed, realizing automatic compensation for the components to be assembled.

[0048] For example, the tolerance compensator 100 is used on a concealed door handle. The concealed door handle forms a first component 110, which includes, but is not limited to, the concealed door handle. The second component 200 includes, but is not limited to, the door sheet metal part. The fixing member 131 includes, but is not limited to, a fixing screw. The locking member 135 has an internal thread that mates with the external thread of the fixing screw, achieving a threaded connection. When installing the concealed door handle, it is required that the installation gap around the concealed door handle be uniform and that there be a fixed height difference between the concealed door handle and the outer arc surface of the door sheet metal part. However, due to certain production and manufacturing errors in the fastening holes of the door sheet metal part during the production process, the tolerance compensator 100 is used to compensate for these errors in order to eliminate their impact on the installation accuracy of the concealed door handle, thereby meeting the installation accuracy requirements.

[0049] like Figure 1 , Figure 2 , Figure 3 and Figure 12As shown, in one embodiment of this application, optionally, the elastic pressure member 133 has a second mounting cavity 1332 and a second through hole 1333 communicating with the second mounting cavity 1332. The pusher 134, the radial adjustment member 140, the locking member 135 and the first component 110 are all located in the second mounting cavity 1332. The fixing member 131 is sequentially inserted through the first through hole 1322, the second through hole 1333, the pusher 134 and the radial adjustment member 140 and is engaged with the locking member 135 in a manner not limited to threaded engagement.

[0050] In this embodiment, during the assembly and fastening process of the components to be assembled (such as fastening the first component 110 to the second component 200) using the tolerance compensator 100, the fixing member 131 is rotated clockwise or counterclockwise so that the fixing member 131 passes through the first through hole 1322, the second through hole 1333, the pusher 134, and the radial adjustment member 140 in sequence and is screwed and fixed with the locking member 135. During the screwing process, the head of the fixing member 131 pushes the fastener 132 to move relative to the base 120, so as to drive the elastic pressure member 133 in the first mounting cavity 1321 to move synchronously with the fastener 132, thereby driving the pusher 134 in the second mounting cavity 1332 to push the radial adjustment member 140 and the first component 110 to move synchronously. When the first component 110 moves to contact the second component 200 and generates friction, the fixing member 131 is rotated again to drive the locking member 135 to move synchronously. As the locking member 135 rotates a preset angle under the action of the fixing member 131, a portion of the locking member 135 abuts against the component to be assembled. The fixing member 131 and the locking member 135 continue to rotate in a manner not limited to threaded engagement to drive the locking member 135 to move along its axial direction, thereby locking the first component 110 and the second component 200. At the same time, when the locking member 135 passes through the connecting hole of the second component 200, the first elastic adjustment part 1331 of the elastic pressure member 133 can perform axial correction and compensation for the entire tolerance compensator 100 and the second component 200, and the second elastic adjustment part 141 of the radial adjustment member 140 can perform radial correction and compensation for the entire tolerance compensator 100 and the second component 200. Finally, the components to be assembled (the first component 110 and the second component 200) are locked and fixed, realizing automatic compensation for the components to be assembled.

[0051] like Figure 2 , Figure 3 , Figure 4 and Figure 12As shown in the above embodiments of this application, optionally, the first elastic adjustment part 1331 is a spring-like structure 13311. One end of the spring-like structure 13311 is fixedly connected to the cavity wall of the second mounting cavity 1332, and the other end extends toward the second mounting cavity 1332, so as to realize that the first elastic adjustment part 1331 undergoes elastic deformation along the axial direction of the first component 110.

[0052] In this embodiment, one end of the spring-like structure 13311 is fixedly connected to the cavity wall of the second mounting cavity 1332, and the other end extends toward the direction of the second mounting cavity 1332, that is, toward the direction of the pusher 134. This facilitates the contact between the spring-like structure 13311 and the pusher 134, thereby realizing the function of the first elastic adjustment part 1331 elastically deforming along the axial direction of the first component 110. This allows the first elastic adjustment part 1331 of the elastic pressure member 133 to perform axial correction and compensation for the entire tolerance compensator 100 and the second component 200, thereby realizing the automatic compensation function for the components to be assembled.

[0053] like Figure 2 , Figure 3 , Figure 5 and Figure 13 As shown in the above embodiments of this application, optionally, the second elastic adjustment part 141 is provided by a spring sheet around the outer periphery of the radial adjustment member 140, so as to realize that the second elastic adjustment part 141 undergoes elastic deformation along the radial direction of the first member 110.

[0054] In this embodiment, the second elastic adjustment part 141 is arranged around the outer periphery of the radial adjustment member 140 by a spring sheet, thereby realizing the function of elastic deformation of the second elastic adjustment part 141 along the radial direction of the first component 110, thereby enabling the second elastic adjustment part 141 to perform radial correction and compensation on the entire tolerance compensator 100 and the second component 200, and realize the automatic compensation function of the component to be assembled.

[0055] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in one embodiment of this application, optionally, the first component 110 has a limiting post 111 and a limiting buckle 112, the base 120 has a limiting hole 122 adapted to the limiting post 111, and a limiting groove 123 adapted to the limiting buckle 112.

[0056] In this embodiment, by providing a limiting post 111 and a limiting buckle 112 on the first component 110, and by providing limiting holes 122 and limiting slots 123 on the base 120 that are respectively adapted to the limiting post 111 and the limiting buckle 112, a guiding and limiting function is achieved, enabling the assembly of the first component 110 and the base 120, allowing the first component 110 to move relative to the base 120. Simultaneously, this also prevents the first component 110 from detaching from the base 120. Furthermore, the engagement of the limiting buckle 112 and the limiting slot 123 facilitates disassembly and assembly, improving assembly efficiency.

[0057] like Figure 2 and Figure 3 As shown, in one embodiment of this application, optionally, the locking member 135 has a slot 1351 on its outer periphery, and the radial adjusting member 140 has a buckle 142 on its inner periphery that is adapted to the slot 1351.

[0058] In this embodiment, by opening a slot 1351 on the outer periphery of the locking member 135 and providing a buckle 142 that matches the slot 1351 on the inner periphery of the radial adjustment member 140, the radial adjustment member 140 is assembled on the locking member 135, thereby enabling the locking member 135 and the radial adjustment member 140 to form an assembly and move synchronously.

[0059] like Figure 2 and Figure 3 As shown, in one embodiment of this application, optionally, the fixing member 131 has a limiting groove 1311 in the circumferential direction, and the radial adjusting member 140 is provided with a limiting rib 143 in the inner circumferential direction that is adapted to the limiting groove 1311.

[0060] In this embodiment, by opening a limiting groove 1311 in the circumferential direction of the fixing member 131 and setting a limiting rib 143 in the inner circumferential direction of the radial adjusting member 140 that is compatible with the limiting groove 1311, the fixing member 131 and the radial adjusting member 140 can rotate synchronously.

[0061] like Figure 2 and Figure 3As shown in the above embodiments of this application, optionally, the locking member 135 includes a locking head 1352 and a connecting post 1353. The locking head 1352 is connected to the connecting post 1353, and the internal thread or internal cavity is provided in the connecting post 1353 to achieve fixation with the external thread of the fixing member 131 in a manner not limited to threaded engagement. After the locking member 135 rotates by a preset angle under the action of the fixing member 131, the locking head 1352 is misaligned and locked with the second component 200. The fixing member 131 and the locking member 135 continue to rotate in a manner not limited to threaded engagement to drive the locking member 135 to move along its axial direction, thereby locking and fixing the first component 110 and the second component 200.

[0062] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown in the above embodiments of this application, optionally, the cavity wall of the receiving cavity 121 is provided with a first type of thread structure 1211, and the outer wall of the fastener 132 is provided with a second type of thread structure 1323 that cooperates with the first type of thread structure 1211.

[0063] In this embodiment, the cavity wall of the receiving cavity 121 of the base 120 is provided with a first type of thread structure 1211, and the outer wall of the fastener 132 is provided with a second type of thread structure 1323 that cooperates with the first type of thread structure 1211. That is, the fastener 132 is threadedly connected to the base 120, which makes it easier for the fastener 132 to move relative to the base 120 under the pushing action of the fixing member 131.

[0064] For example, the first type of thread structure 1211 can be a helical protrusion, and the second type of thread structure 1323 can be a helical groove that mates with the helical protrusion. Of course, the first type of thread structure 1211 can also be a helical groove, and the second type of thread structure 1323 can be a helical protrusion that mates with the helical groove.

[0065] like Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, this application embodiment also provides an assembly assembly 1000, which includes a first component 110, a second component 200, and a tolerance compensator 100 as described in any of the above embodiments. The tolerance compensator 100 is disposed on the first component 110 and is used to fasten the first component 110 and the second component 200.

[0066] For example, the assembly assembly 1000 takes a concealed door handle and a door sheet metal as an example. The first component 110 is a concealed door handle, and the second component 200 is a door sheet metal. The tolerance compensator 100 is pre-installed on the concealed door handle as an example. In this way, when the first component 110 is assembled onto the second component 200, by rotating the fixing member 131, the locking member 135 rotates at a preset angle under the action of the fixing member 131 and locks itself off-center from the second component 200. The fixing member 131 and the locking member 135 continue to rotate in a manner not limited to threaded engagement to drive the locking member 135 to move along its axial direction, thereby locking and fixing the concealed door handle and the door sheet metal. At the same time, the first elastic adjustment part 1331 of the elastic pressure member 133 achieves axial error compensation, and the second elastic adjustment part 141 of the radial adjustment member 140 achieves radial error compensation. Finally, the components to be assembled are locked and fixed, realizing the automatic compensation function of the components to be assembled.

[0068] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
