[0041] like Figure 1 As shown, an embodiment of the present application provides a tolerance compensator 100, which is mainly used for assembling and fixing parts to be assembled, especially in the field of automotive accessories. For the convenience of description, in this embodiment, the first component 200 and the second component 300 of the assembly assembly are assembled and fastened, and the tolerance compensator 100 is preset on the first component 200 and is assembled and fastened with the second component 300 as an example for description.

[0042] like Figure 6 As shown, the tolerance compensator 100 includes a first compensation element 110 and a second compensation element 120. The first compensation element 110 is arranged in the accommodating cavity 210, and includes a first fastener 111, a second fastener 112 and a locking member 113. The first fastener 111 has an external thread, and the locking member 113 is provided with an internal screw hole or an internal hole matching the external thread. The second fastener 112 has an installation cavity 1121 and a through hole 1122 communicating with the installation cavity 1121. The first fastener 111 is inserted into the through hole 1122 and is threadedly engaged with the locking member 113. When the locking member 113 rotates at a preset angle under the action of the first fastener 111, the first fastener 111 continues to be threadedly engaged with the locking member 113 to drive the locking member 113 to move along its axial direction.

[0043] See also Figures 2 to 5 An elastic compensation portion 121 is provided on the outer circumference of the second compensation element 120, and the elastic compensation portion 121 is located in the installation cavity 1121 and abuts against the inner cavity wall of the installation cavity 1121. The locking member 113 is passed through the second compensation element 120, and one end of the second compensation element 120 abuts against one end of the second fastener 112 close to the second component 300.

[0044] The tolerance compensator 100 provided in the embodiment of the present application is pre-installed on the first component 200. When the second component 300 is fastened to the first component 200, an assembly hole is opened on the second component 300, and the first fastener 111 is rotated clockwise or counterclockwise to make the first fastener 111 and the locking member 113 threadedly engaged. During the threaded engagement process, the head of the first fastener 111 is used to push the second fastener 112 to move relative to the first component 200, thereby pushing the second compensation element 120 to move synchronously, so that the second compensation element 120 is abutted against the second component 300 to perform correction compensation in the axial direction, thereby realizing axial error compensation.

[0045] At the same time, the locking member 113 is first synchronously rotated by a preset angle under the action of the first fastener 111, and then the first fastener 111 and the locking member 113 are threadedly screwed together to drive the locking member 113 to move along its axial direction, thereby locking the first component 200 and the second component 300. At the same time, when the locking member 113 passes through the assembly hole of the second component 300, the elastic compensation portion 121 of the second compensation element 120 can correct and compensate the entire tolerance compensator 100 and the second component 300 in the radial direction, realize radial error compensation, and finally lock and fix the components to be assembled (the first component 200 and the second component 300) to realize automatic compensation of the components to be assembled.

[0046] Exemplarily, the tolerance compensator 100 is used on a hidden door handle, the hidden door handle forms a first component 200, the first component 200 includes but is not limited to the hidden door handle, the second component 300 includes but is not limited to the door sheet metal, the first fastener 111 includes but is not limited to the fixing screw, and the elastic compensation part 121 can be formed by continuously bending the spring sheet around the outer circumference of the elastic compensation part to achieve elastic deformation of the elastic compensation part 121 along the radial direction of the installation cavity 1121. When installing the hidden door handle, it is required that the installation gap around the hidden door handle is uniform and has a fixed height difference with the outer arc surface of the door sheet metal. Since the assembly hole of the door sheet metal has certain production and manufacturing errors during the production process, in order to eliminate the influence of such errors on the installation accuracy of the hidden door handle, it is necessary to use the tolerance compensator 100 to compensate for the error, so as to meet the installation accuracy requirements.

[0047] like Figure 6 , Fig. 9 and Fig.10 As shown, in one embodiment of the present application, optionally, a limiting groove 122 is provided in the inner circumference of the second compensation element 120. The locking member 113 includes a clamp head 1131 and a column 1132, the clamp head 1131 is connected to the column 1132, and a protrusion 11321 is provided in the outer circumference of one end of the column 1132 away from the clamp head 1131, and the protrusion 11321 is provided with a mounting hole 113211 or a mounting groove.

[0048] The tolerance compensator 100 also includes a limit member 130 and an elastic member 140. The limit member 130 is sleeved on one end of the column 1132 close to the clamping head 1131, and the outer circumference of the limit member 130 is provided with a limit protrusion 131 adapted to the limit groove 122. The elastic member 140 includes a main body 141, a first elastic arm 142 and a second elastic arm 143. The first elastic arm 142 and the second elastic arm 143 are respectively located at the two ends of the main body 141. The main body 141 is sleeved on the column 1132. The first elastic arm 142 is installed in the mounting hole 113211 or the mounting groove. The second elastic arm 143 is arranged in the limiting groove 122 and abuts against the limiting protrusion 131.

[0049] Therefore, in the process of threading the first fastener 111 and the locking member 113 to drive the locking member 113 to move along its axial direction, the second elastic arm 143 does not rotate under the limiting action of the limiting groove 122, and the first elastic arm 142 and the main body 141 rotate synchronously with the locking member 113 to generate a reset torque. At the same time, the limiting member 130 moves synchronously along the axial direction with the locking member 113, so that the limiting protrusion 131 of the limiting member 130 moves synchronously along the axial direction in the limiting groove 122, and then under the abutment and extrusion action of the limiting protrusion 131, the second elastic arm 143 is pushed to move synchronously along the axial direction in the limiting groove 122, so as to drive the main body 141 to be compressed along the axial direction to generate a reset elastic force. In this way, when the tolerance compensator 100 needs to be replaced and disassembled, by rotating the first fastener 111 counterclockwise or clockwise, the locking member 113 and the limit member 130 are automatically reset under the dual action of the reset torque and the reset elastic force, thereby facilitating the removal of the clamping head 1131 from the assembly hole of the second component 300, avoiding the technical problems in the prior art that the tolerance compensator has a complex structure, is difficult to replace, and can only be disassembled and assembled destructively, is time-consuming and labor-intensive, and cannot be reused, resulting in high costs.

[0050] like Figure 6 , Fig. 9 and Fig.10 As shown, in the above embodiment of the present application, optionally, a first positioning protrusion 11311 is provided at one end of the clamping head 1131 close to the column 1132 , and a second positioning protrusion 132 matching the first positioning protrusion 11311 is provided at one end of the limiting member 130 close to the clamping head 1131 .

[0051] In this embodiment, a first positioning protrusion 11311 is provided at one end of the clamping head 1131 close to the column 1132, and a second positioning protrusion 132 matching with the first positioning protrusion 11311 is provided at one end of the limiting member 130 close to the clamping head 1131, so that in the process of threading the first fastener 111 and the locking member 113 together to drive the locking member 113 to move along its axial direction, the clamping head 1131 is guided and limited, so that the first positioning protrusion 11311 of the clamping head 1131 slides along the guiding inclined surface of the second positioning protrusion 132, thereby locking the first component 200 and the second component 300.

[0052] like Figure 6 and Fig. 9 As shown, in the above embodiment of the present application, optionally, a plurality of third positioning protrusions 123 are provided at one end of the second compensation element 120 close to the second component 300 , and the plurality of third positioning protrusions 123 are arranged at intervals along the circumference of the column 1132 .

[0053] In this embodiment, a plurality of third positioning protrusions 123 spaced circumferentially along the column 1132 are provided at one end of the second compensation element 120 close to the second component 300, so as to guide and limit the chuck 1131 in the process of threading the first fastener 111 and the locking member 113 together to drive the locking member 113 to move along its axial direction, so that the chuck 1131 slides along the guiding inclined surface of the third positioning protrusion 123, thereby locking the first component 200 and the second component 300.

[0054] like Figure 2 , Figure 6 and Figure 7 As shown, in one embodiment of the present application, optionally, the tolerance compensator 100 further includes an annular member 150 , and the annular member 150 is engaged with the first component 200 .

[0055] Exemplarily, a buckle is provided on the ring member 150, and a clamping hole is provided on the first component 200, and the buckle cooperates with the clamping hole to fix the ring member 150 on the first component 200, so that the first compensation element 110 and the second compensation element 120 are prevented from falling off from the first component 200. In addition, the clamping connection between the ring member 150 and the first component 200 facilitates disassembly and assembly, thereby improving assembly efficiency.

[0056] like Figure 7 and Figure 8As shown, in the above-mentioned embodiment of the present application, optionally, the annular member 150 protrudes and extends toward one side of the accommodating cavity 210 to form a positioning groove body 151, a positioning column 124 is provided on the second compensation element 120, and the positioning groove body 151 and the inner cavity wall of the installation cavity 1121 form a positioning cavity 1511, the positioning column 124 is inserted into the positioning cavity 1511, and a first clamping portion 1241 is provided on the positioning column 124, and a second clamping portion 1123 matching the first clamping portion 1241 is provided on the inner circumference of the second fastener 112.

[0057] In this embodiment, the positioning column 124 cooperates with the positioning groove 151 of the ring member 150, so that after the second compensation element 120 is assembled with the second fastener 112, the radial direction is restricted and positioned, so as to prevent the second compensation element 120 from rotating when the first fastener 111 rotates. At the same time, by inserting the positioning column 124 into the positioning cavity 1511 and engaging the second clamping portion 1123 in the inner circumference of the second fastener 112 through the first clamping portion 1241, the second compensation element 120 is restricted and positioned in the axial direction after being assembled with the second fastener 112, so as to prevent the second compensation element 120 from being separated from the second fastener 112 together with the locking member 113 when the first fastener 111 is locked or loosened.

[0058] Exemplarily, the first clamping portion 1241 may be a buckle, and the second clamping portion 1123 may be an annular groove that cooperates with the buckle, and the second compensation element 120 may be fixed to the second fastener 112 through the cooperation between the buckle and the annular groove.

[0059] like Figure 7 and Figure 8 As shown, in the above embodiment of the present application, optionally, a limiting hole 1124 for the positioning groove 151 and the positioning column 124 to pass through is opened on the second fastener 112 .

[0060] Thus, under the action of the limiting hole 1124 and the positioning column 124, when the second fastener 112 is assembled into the accommodating cavity 210 of the first component 200, it can only rotate within the accommodating cavity 210 by a preset angle, so that the tolerance compensator 100 and the second component 300 reach the preset position first.

[0061] like Figure 3 , Figure 5 and Figure 6 As shown, in the above embodiments of the present application, optionally, in a direction perpendicular to the axis of the column 1132 , the cross-section of the clamping head 1131 is any one of a polygon, a strip, a cross, an I-shape, a semicircle or an ellipse.

[0062] For example, in this embodiment, the cross-sectional shape of the clamp head 1131 in the axial direction of the column 1132 is exemplified as a square, but is not limited thereto, and may also be a triangle, a strip, a cross, an I-shaped, a semicircle, an ellipse, or the like.

[0063] like Figure 7 As shown, in any of the above embodiments of the present application, optionally, the inner wall of the accommodating cavity 210 is provided with a first type of thread 211 , and the outer wall of the second fastener 112 is provided with a second type of thread 1125 matching the first type of thread 211 .

[0064] In this embodiment, axial compensation is performed by screwing the first type thread 211 of the first component 200 and the second type thread 1125 of the second fastener 112 together to achieve compensation for axial tolerance.

[0065] Exemplarily, the first type of thread 211 may be a spiral protrusion, and the second type of thread 1125 may be a spiral groove. It is understandable that the first type of thread 211 may be a spiral groove, and the second type of thread 1125 may be a spiral protrusion.

[0066] An embodiment of the present application also provides an assembly component, which includes a first component 200, a second component 300 and the tolerance compensator 100 described in any of the above embodiments, wherein the tolerance compensator 100 is arranged on the first component 200, and the tolerance compensator 100 is used to fasten the first component 200 and the second component 300.

[0067] Exemplarily, the assembly components take a hidden door handle and a door sheet metal as an example, the first component 200 is the hidden door handle, the second component 300 is the door sheet metal, and the tolerance compensator 100 pre-installed on the hidden door handle is used as an example for description. In this way, when the first component 200 is assembled to the second component 300, the first fastener 111 is rotated so that the first fastener 111 and the locking member 113 are threadedly screwed together. During the threaded screwing process, the head of the first fastener 111 is used to push the second fastener 112 to move relative to the first component 200, thereby pushing the second compensation element 120 to move synchronously, so that the second compensation element 120 abuts against the second component 300 to perform correction compensation in the axial direction to achieve axial error compensation. At the same time, the locking member 113 is rotated by a preset angle under the action of the first fastener 111, and the first fastener 111 and the locking member 113 are continuously threadedly screwed and rotated to drive the locking member 113 to move along its axial direction, thereby locking and fixing the hidden door handle and the door sheet metal. At the same time, radial error compensation is achieved under the action of the elastic compensation portion 121 of the second compensation element 120, and finally the components to be assembled are locked and fixed, thereby achieving automatic compensation of the components to be assembled.
