[0044] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in the template description herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0049] like Figures 1 to 5 As shown, an embodiment of the present application provides a tolerance compensator 100, which is primarily used in applications requiring high precision in fastening and assembly, particularly where the fixed component itself has dimensional and positioning errors, resulting in the fixed component being unable to be properly installed or being installed out of position. The tolerance compensator 100 includes a first adjustment member 110, a second adjustment member 120, an axial adjustment assembly 140, and a radial adjustment member 150.

[0050] The second adjusting member 120 is disposed on one side of the first adjusting member 110 to define an accommodating cavity 115 , and a preset member 130 is provided on a side of the second adjusting member 120 away from the first adjusting member 110 .

[0051] The axial adjustment component 140 is arranged in the accommodating cavity 115. The axial adjustment component 140 includes a fastener 141, a pushing member 142 and a mounting member 143. The mounting member 143 is provided with a mounting hole 1431 adapted to the fastener 141. The pushing member 142 is sleeved on the circumference of the fastener 141 and abuts between the fastener 141 and the second adjusting member 120. A first protrusion 111 is provided along the inner circumference of the first adjusting member 110, and a second protrusion 1432 adapted to the first protrusion 111 is provided along the circumference of the mounting member 143.

[0052] See also Figures 10 to 14 The radial adjustment member 150 is arranged in the accommodating cavity 115, and the outer circumferential wall of the radial adjustment member 150 abuts against the cavity wall of the accommodating cavity 115. An adjustment portion 151 abutting against the mounting member 143 is provided along the inner circumference of the radial adjustment member 150.

[0053] The tolerance compensator 100 provided in the embodiment of the present application is configured such that the outer circumferential wall of the radial adjustment member 150 abuts against the cavity wall of the accommodating cavity 115, so that the radial adjustment member 150 is fixedly installed in the accommodating cavity 115. At the same time, an adjustment portion 151 abutting against the mounting member 143 is provided on the inner circumference of the radial adjustment member 150, and the radial position of the mounting member 143 relative to the preset member 130 is automatically adjusted by using the adjustment portion 151.

[0054] Exemplarily, the adjustment portion 151 may be an elastic arm 1511 that abuts against the mounting member 143 and deforms, thereby automatically adjusting the radial position of the mounting member 143 relative to the preset member 130. The adjustment portion 151 may be integrally formed with the radial adjustment member 150 through injection molding, or may be fixed by other means. The adjustment portion 151 may be an arcuate segment 15112, a combination of an arcuate segment 15112 and a straight segment 15111, or may have other shapes.

[0055] Specifically, the mounting member 143 is provided with a mounting hole 1431 that matches the fastener 141, so that the fastener 141 can be screwed into the mounting hole 1431 of the mounting member 143. The pushing member 142 is sleeved around the fastener 141 and abuts between the fastener 141 and the second adjusting member 120. In this way, when the fastener 141 is screwed into the mounting hole 1431, the pushing member 142 can be driven to push the second adjusting member 120 in a direction away from the first adjusting member 110. The first adjusting member 110 is provided with a first protrusion 111 on the inner circumference, and the mounting member 143 is provided with a second protrusion 1432 on the circumference that is adapted to the first protrusion 111. After the fastener 141 is screwed into the mounting hole 1431, it can drive the mounting member 143 to rotate synchronously. The first adjusting member 110 is driven to rotate synchronously by the cooperation between the second protrusion 1432 of the mounting member 143 and the first protrusion 111 of the first adjusting member 110, and the second adjusting member 120 abuts against the pushing member 142 to have friction, so that the second adjusting member 120 does not rotate synchronously with the first adjusting member 110, that is, the second adjusting member 120 rotates in the opposite direction relative to the first adjusting member 110, so that the second adjusting member 120 moves in a direction away from the first adjusting member 110, thereby realizing automatic adjustment of the axial position of the second adjusting member 120 relative to the preset member 130.

[0056] It should be noted that the first adjusting member 110, the second adjusting member 120, the axial adjusting assembly 140 and the radial adjusting member 150 are combined to form a fixed member, and the preset member 130 is a fixed member, that is, the fixed member is installed on the preset member 130. When there is a position error in the preset member 130, such as when the position is tilted or offset, it is difficult to install the fixed member on the preset member 130, or when it is installed on the preset member 130, the fixed member also presents a position tilt or offset phenomenon, which will correspondingly make it difficult for the fixed member to achieve the corresponding function, or other problems will arise.

[0057] By providing the radial adjustment member 150 to automatically adjust the radial position of the mounting member 143 relative to the preset member 130, and by providing the axial adjustment assembly 140 to automatically adjust the axial position of the second adjustment member 120 relative to the preset member 130, automatic tolerance compensation is achieved. This ensures that when the preset member 130 has a positional error (tilt or offset), the resulting offset or tilt is eliminated during installation and fixation of the fixed member. The tolerance compensator 100 compensates for a certain degree of spatial error in the preset member 130, ensuring the accuracy of the fixed member's spatial installation position.

[0058] Exemplarily, the tolerance compensator 100 is used on a concealed door handle. The fixed part formed by the combination of the first adjustment member 110, the second adjustment member 120, the axial adjustment assembly 140, and the radial adjustment member 150 includes, but is not limited to, a concealed door handle. The pre-set member 130 includes, but is not limited to, a door sheet metal. The fastener 141 includes, but is not limited to, a fastening screw. The mounting hole 1431 has an internal thread that matches the external thread of the fastening screw to achieve a threaded connection. When installing a concealed door handle, the concealed door handle is required to have a uniform installation gap around it and a fixed height difference with the outer arc surface of the door sheet metal. Since the fastening holes of the door sheet metal have certain production and manufacturing errors during the production process, in order to eliminate the impact of such errors on the installation accuracy of the concealed door handle, it is necessary to use the tolerance compensator 100 to compensate for the errors and meet the installation accuracy requirements.

[0059] like Figure 2 and Figure 3 As shown, in one embodiment of the present application, optionally, the first adjusting member 110 is provided with an external thread 112 , and the second adjusting member 120 is provided with an internal thread 121 adapted to the external thread 112 .

[0060] In this embodiment, an external thread 112 is provided on the first adjusting member 110, and an internal thread 121 is provided on the second adjusting member 120, which is compatible with the external thread 112 of the first adjusting member 110. By connecting the first adjusting member 110 and the second adjusting member 120 through threads, the relative axial adjustment of the first adjusting member 110 and the second adjusting member 120 can be facilitated.

[0061] For example, the second adjusting member 120 may be provided with a thread-like structure, and the first adjusting member 110 may be provided with a matching groove that cooperates with the thread-like structure. In actual application, the thread-like structure and the matching groove can be interchangeable to improve interchangeability, that is, the first adjusting member 110 may be provided with a thread-like structure, and the second adjusting member 120 may be provided with a matching groove that cooperates with the thread-like structure.

[0062] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, optionally, the pushing

[0063] The member 142 includes a first abutting portion 1421 and a second abutting portion 1422 . The second abutting portion 1422 is disposed circumferentially of the first abutting portion 1421 . The first abutting portion 1421 abuts against the fastener 141 , and the second abutting portion 1422 abuts against the second adjusting member 120 .

[0064] In this embodiment, the second abutting portion 1422 is arranged on the circumference of the first abutting portion 1421, and the first abutting portion 1421 is sleeved on the circumference of the fastener 141, so that the first abutting portion 1422 is

[0065] The portion 1421 and the second abutting portion 1422 are respectively abutted against the fastener 141 and the second adjusting member 120, so that the pushing member 142 is sleeved on the circumference of the fastener 141 and abuts between the fastener 141 and the second adjusting member 120, and then, in the process of the fastener 141 being screwed into the mounting hole 1431, the pushing member 142 can be driven to push the second adjusting member 120 in the direction away from the first adjusting member 110, thereby automatically adjusting the axial position of the second adjusting member 120 relative to the preset member 130 and realizing automatic compensation of tolerance in the axial direction.

[0066] 5 For example, the first abutting portion 1421 and the second abutting portion 1422 may be integrally formed.

[0067] The second abutting portion 1422 may be provided in plurality, and the plurality of second abutting portions 1422 are arranged at intervals along the circumference of the first abutting portion 1421 and all abut against the second adjusting member 120 .

[0068] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 7 、 Figure 8 and Figure 9 As shown, in the above-mentioned embodiment 0 of the present application, optionally, a guide groove 113 adapted to the second abutting portion 1422 is opened along the inner circumference of the first adjusting member 110 .

[0069] In this embodiment, a guide groove 113 adapted to the second abutting portion 1422 is provided along the inner circumference of the first adjusting member 110. The guide groove 113 plays a guiding role so that the first adjusting member 110 can be tightened.

[0070] When the fixing member 141 is screwed into the mounting hole 1431, the pushing member 142 is driven to push the second adjusting member 120 to move in the direction away from the first adjusting member 110, thereby automatically adjusting the second adjusting member 120 relative to the first adjusting member 110.

[0071] The axial position of the preset component 130 realizes automatic compensation of tolerance in the axial direction.

[0072] For example, the number of the guide grooves 113 may be multiple, and the multiple guide grooves 113 are spaced apart along the inner circumference of the first adjusting member 110 .

[0073] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, in one embodiment of the present application, optionally, a locking protrusion 152 is provided along the outer circumference of the radial adjustment member 150 , and a locking groove 114 adapted to the locking protrusion 152 is opened along the inner circumference of the first adjustment member 110 .

[0074] In this embodiment, a locking protrusion 152 is provided on the outer circumference of the radial adjustment member 150, and a locking groove 114 adapted to the locking protrusion 152 is opened on the inner circumference of the first adjustment member 110, so that the radial adjustment member 150 is firmly installed in the accommodating cavity 115 of the first adjustment member 110, so that the adjusting portion 151 of the radial adjustment member 150 is in contact with the mounting member 143 and deformed, and then the mounting member 143 is automatically adjusted to the radial position corresponding to the preset member 130, thereby realizing automatic compensation of tolerance in the radial direction.

[0075] Exemplarily, there are multiple latching protrusions 152 and multiple latching grooves 114, multiple latching protrusions 152 are arranged at intervals along the outer circumference of the radial adjustment member 150, multiple latching grooves 114 are arranged at intervals along the inner circumference of the first adjustment member 110, multiple latching protrusions 152 are arranged corresponding to multiple latching grooves 114, and multiple latching grooves 114 are arranged at intervals from multiple guide grooves 113.

[0076] like Figure 5 and Figure 7As shown, in one embodiment of the present application, optionally, the adjustment portion 151 is an elastic arm 1511, and the elastic arm 1511 includes a straight segment 15111 and an arc segment 15112, and the straight segment 15111 is respectively connected to the radial adjustment member 150 and the arc segment 15112, and the arc segment 15112 is in contact with the mounting member 143 on the side away from the radial adjustment member 150.

[0077] In this embodiment, the adjustment portion 151 is an elastic arm 1511, which includes a straight segment 15111 and an arc segment 15112. The straight segment 15111 is respectively connected to the radial adjustment member 150 and the arc segment 15112. The connection method can be one-piece injection molding or other fixing methods. The side of the arc segment 15112 away from the radial adjustment member 150 abuts against the mounting member 143 to generate deformation, thereby automatically adjusting the radial position of the mounting member 143 corresponding to the preset member 130, thereby realizing automatic compensation of tolerance in the radial direction.

[0078] It should be noted that the abutment portion between the mounting member 143 and the arc segment 15112 is an arc-shaped surface, so as to improve the smoothness of the movement of the mounting member 143 .

[0079] like Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, in the above embodiment of the present application, optionally, a limiting column 1433 is provided along the circumference of the mounting member 143 , and one end of the arc segment 15112 away from the straight segment 15111 abuts against the limiting column 1433 .

[0080] In this embodiment, a limiting column 1433 is provided on the circumference of the mounting member 143, and the end of the arc segment 15112 away from the straight segment 15111 abuts against the limiting column 1433, so as to play a limiting role in the pre-installation and screwing process of the fastener 141 and the mounting member 143, that is, during the pre-installation and screwing process, a part of the fastener 141 is screwed into the mounting hole 1431 of the mounting member 143, and during this process, the mounting member 143 does not rotate synchronously with the fastener 141.

[0081] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, in the above-mentioned embodiment of the present application, optionally, a plurality of the elastic arms 1511 and the limiting columns 1433 are provided, and the plurality of the elastic arms 1511 are arranged at intervals along the inner circumference of the radial adjustment member 150, and the plurality of the limiting columns 1433 are arranged at intervals along the circumference of the mounting member 143.

[0082] In this embodiment, multiple elastic arms 1511 and multiple limiting posts 1433 are provided, and the multiple elastic arms 1511 are spaced apart along the inner circumference of the radial adjustment member 150 to surround the circumference of the mounting member 143 and abut against the mounting member 143 to deform, thereby automatically adjusting the radial position of the mounting member 143 relative to the preset member 130. The multiple limiting posts 1433 are spaced apart along the circumference of the mounting member 143 to correspond to the multiple elastic arms 1511, thereby enhancing the limiting effect.

[0083] like Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14 As shown, in one embodiment of the present application, optionally, the mounting member 143 is provided with a clamping portion 1434, and the clamping portion 1434 is located on the side of the preset member 130 away from the second adjusting member 120, and the first adjusting member 110, the second adjusting member 120 and the preset member 130 are all provided with a through hole 160 adapted to the clamping portion 1434, and the clamping portion 1434 is passed through the through hole 160 and clamped with the side of the preset member 130 away from the second adjusting member 120.

[0084] In this embodiment, the clamping portion 1434 of the mounting member 143 is located on the side of the preset member 130 away from the second adjusting member 120, and the first adjusting member 110, the second adjusting member 120 and the preset member 130 are all provided with a through hole 160 adapted to the clamping portion 1434, so that the clamping portion 1434 can be passed through the through hole 160 and rotated a certain angle to be clamped with the side of the preset member 130 away from the second adjusting member 120, thereby realizing fixed installation between the fixed member and the preset member 130.

[0085] like Figure 11 、 Figure 13 、 Figure 15 and Figure 16 As shown, in the above embodiment of the present application, optionally, the projection shape of the clamping portion 1434 on the preset component 130 is a square or a triangle.

[0086] In this embodiment, the projection of the engaging portion 1434 onto the prefabricated member 130 is a square or triangular shape, and the through hole 160 is correspondingly shaped. Specifically, the engaging portion 1434 is inserted through the through hole 160 and, after rotating a certain angle, engages with the side of the prefabricated member 130 away from the second adjusting member 120, thereby securing the fixed member to the prefabricated member 130.

[0087] Preferably, the projection of the clamping portion 1434 onto the preset component 130 is a triangle. Compared to a square with the same area and a triangle with the same area, after being rotated by a certain angle, the clamping area generated by the triangle is larger than that generated by the square. That is, the clamping area between the triangular clamping portion 1434 and the preset component 130 is larger than the clamping area between the square clamping portion 1434 and the preset component 130. As a result, the triangular clamping portion 1434 is more securely clamped than the square clamping portion 1434, and has higher stability.
