[0061] like Figures 18 to 22 As shown, an embodiment of the present application provides a tolerance compensator 100, primarily used for assembling and securing components to be assembled, particularly in the automotive accessories field. For ease of description, this embodiment assembles and secures a first component 110 and a second component 200 of an assembly. The tolerance compensator 100 is pre-set on the first component 110 and is then assembled and secured to the second component 200.
[0062] like Figures 1 to 3 As shown, the tolerance compensator 100 includes a first compensating element 120 and a second compensating element 130 , wherein the first compensating element 120 includes a fixing member 121 , a fastening member 122 , a clamping member 123 and a locking member 124 .
[0063] Combine Figure 16 As shown, the first component 110 has a receiving cavity 1101 , and the tolerance compensator 100 is pre-installed on the first component 110 .
[0064] See also Figure 4 and Figure 5 As shown, the first compensation element 120 is disposed in the accommodating cavity 1101, the fixing member 121 has an external thread, and the locking member 124 has an internal thread that matches the external thread. Figure 10 and Figure 11 As shown, the fastener 122 has an installation cavity 1221 and a through hole 1222 communicating with the installation cavity 1221. The clamping member 123 is located in the installation cavity 1221 and has a first type of thread structure 1231 therein. The locking member 124 has a second type of thread structure 12421 on its exterior that matches the first type of thread structure 1231. The fixing member 121 is sequentially inserted through the through hole 1222 and the clamping member 123 and is threadedly engaged with the locking member 124. When the locking member 124 rotates by a preset angle under the action of the fixing member 121 and the clamping member 123, the fixing member 121 continues to threadably engage with the locking member 124, driving the locking member 124 to move along its axial direction.
[0065] It should be noted that, for the convenience of description, Figure 3 and Figure 4 As shown, the axial direction is the Y direction in the figure, and the radial direction is the X direction and the Z direction in the figure.
[0066] Combine Figures 6 to 8 As shown, the second compensation element 130 is provided with an elastic adjustment portion 131, which is located in the installation cavity 1221 and abuts against the inner cavity wall of the installation cavity 1221 of the fastener 122, and the locking member 124 is passed through the second compensation element 130, and one end of the second compensation element 130 abuts against one end of the fastener 122 close to the second component 200, and the other end of the second compensation element 130 abuts against the clamping member 123.
[0067] Continue reading Figure 21 and Figure 22The tolerance compensator 100 provided in the embodiment of the present application is pre-installed on the first component 110, and when the second component 200 is fastened to the first component 110, a connecting hole 201 is opened on the second component 200. By rotating the fixing member 121 clockwise or counterclockwise, when the locking member 124 rotates a preset angle under the action of the fixing member 121 and the clamping member 123, the first type of threaded structure 1231 of the clamping member 123 and the second type of threaded structure 12421 of the locking member 124 cooperate to prevent the locking member 124 from continuing to rotate. At this time, the locking member 124 passes through a part of the connecting hole 201 of the second component 200 and is misaligned and hooked with the second component 200 to limit the position.
[0068] Continue to rotate the fixing member 121 and the locking member 124 in a threaded engagement to drive the locking member 124 to move along its axial direction, thereby locking the first component 110 and the second component 200. During this process, when the fixing member 121 continues to be rotated, the first component 110 and the second component 200 are locked and fixed through the entire tolerance compensator 100. At the same time, when the locking member 124 passes through the connecting hole 201 of the second component 200, the elastic adjustment portion 131 of the second compensation element 130 can correct and compensate the entire tolerance compensator 100 and the second component 200 in the radial direction, thereby realizing radial error compensation, and finally locking and fixing the components to be assembled, realizing automatic compensation of the components to be assembled, avoiding the situation in the prior art where nuts need to be welded on the components, resulting in low assembly efficiency and easy falling off, thereby improving assembly efficiency and reliability.
[0069] Exemplarily, the tolerance compensator 100 is used on a concealed door handle. The concealed door handle comprises a first component 110, which includes but is not limited to the concealed door handle; a second component 200, which includes but is not limited to a door sheet metal; a fixing component 121, which includes but is not limited to a fixing screw; and a locking component 124, which has an internal thread that mates with the external thread of the fixing screw to achieve a threaded connection. When installing the concealed door handle, the concealed door handle is required to have a uniform installation gap around it and a fixed height difference from the outer curved surface of the door sheet metal. However, due to certain production and manufacturing errors in the fastening holes of the door sheet metal during the production process, the tolerance compensator 100 is required to compensate for these errors to meet the installation accuracy requirements in order to eliminate the impact of these errors on the installation accuracy of the concealed door handle.
[0070] like Figure 15As shown, the clamping member 123 is exemplarily a cylindrical structure that facilitates the insertion of a fixing screw. A first type of threaded structure 1231 is disposed within the cylindrical structure, and a second type of threaded structure 12421 is disposed on the locking member 124. The first type of threaded structure 1231 can be a spiral groove, and the second type of threaded structure 12421 can be a spiral protrusion. It is understood that the first type of threaded structure 1231 can also be a spiral protrusion, and the second type of threaded structure 12421 can be a spiral groove.
[0071] like Figure 13 and Figure 14 As shown, in one embodiment, optionally, the second compensation element 130 is provided with a cavity 132, the elastic adjustment portion 131 is arranged along the outer circumference of the cavity 132, and an annular plate 133 is provided inside the cavity 132, and the annular plate 133 divides the interior of the cavity 132 into a connected first cavity 1321 and a second cavity 1322.
[0072] Combine Figure 12 As shown, the locking member 124 includes a locking clamp 1241 and a connecting column 1242, the locking clamp 1241 is connected to the connecting column 1242, and the internal thread is arranged in the connecting column 1242, and the second type thread structure 12421 is arranged on the outer circumference of the connecting column 1242.
[0073] See also Figure 7 The tolerance compensator 100 also includes an elastic member 140 and a positioning member 150. The positioning member 150 and the elastic member 140 are both sleeved on the connecting column 1242. The elastic member 140 is located in the first cavity 1321, and one end of the elastic member 140 abuts against the positioning member 150, and the other end abuts against the annular plate 133. The end of the clamping member 123 close to the elastic member 140 abuts against the annular plate 133 and is partially located in the second cavity 1322.
[0074] like Figure 15 As shown, the cross-section of the positioning member 150 is non-circular in a direction perpendicular to the axis of the connecting column 1242. The second compensation element 130 is provided with a special-shaped hole communicating with the first cavity 1321. The shape of the special-shaped hole matches the cross-sectional shape of the positioning member 150. This allows the positioning member 150 to form radial interference positioning with the cavity wall of the first cavity 1321.
[0075] Exemplarily, the irregularly shaped hole is square, and the shape of the positioning member 150 matches it. Of course, the opening of the first cavity 1321 can also be irregularly shaped (such as a pentagon, triangle, ellipse, etc.), which is limited to non-circular structures.
[0076] In this embodiment, during assembly, the positioning member 150 is sleeved on the connecting column 1242 and abuts against the side of the locking clamp 1241 facing the connecting column 1242. The elastic member 140 is supported between the positioning member 150 and the annular plate 133. At the same time, the elastic member 140 is located in the first cavity 1321, and a part of the clamping member 123 is located in the second cavity 1322 and abuts against the annular plate 133, thereby forming the above components into an assembly. The positioning member 150 is provided so that, when assembled with the connecting hole 201 of the second component 200, the radial cross-sectional shape of the positioning member 150 matches the shape of the connecting hole 201. Thus, when the tolerance compensator 100 is assembled to the second component 200, the positioning member 150 positions the second compensation element 130 relative to the second component 200. Specifically, after the positioning member 150 is inserted into the connecting hole 201 of the second component 200, the second compensation element 130 cannot rotate due to the positioning member 150. Furthermore, the elastic member 140 provides elastic support for the positioning member 150, allowing the positioning member 150 to move freely along the axial direction, i.e., the Y direction.
[0077] It should be noted that, illustratively, the elastic member 140 in the above embodiment is a cylindrical spring.
[0078] like Figure 13 and Figure 15 As shown, in the above embodiment, to facilitate the assembly of the clip 123 and the second compensation element 130, a guide protrusion 13221 is provided on the inner wall of the second cavity 1322, and a guide groove 1232 is formed on the exterior of the clip 123 to cooperate with the guide protrusion 13221. Thus, when assembling the clip 123, the guide protrusion 13221 of the clip 123 moves along the guide groove 1232, thereby facilitating the assembly of the clip 123 and making its assembly position more precise. At the same time, the guide protrusion 13221 cooperates with the guide groove 1232 to provide a positioning function, preventing the clip 123 and the second compensation element 130 from rotating relative to each other.
[0079] like Figures 3 to 5 As shown, in any of the above embodiments, optionally, the tolerance compensator 100 further includes an annular base 160 , and the annular base 160 is engaged with the first component 110 .
[0080] Combine Figure 17 and Figure 18As shown, for example, a buckle 162 is provided on the annular base 160, and a locking hole 112 is provided on the first component 110. The buckle 162 cooperates with the locking hole 112 to fix the annular base 160 to the first component 110, thereby preventing the first compensation element 120 and the second compensation element 130 from falling off the first component 110. In addition, the locking connection between the annular base 160 and the first component 110 facilitates disassembly and assembly, thereby improving assembly efficiency.
[0081] It is understood that, for example, three clips 162 are provided, and the three clips 162 are arranged along the circumference of the annular base 160. Correspondingly, three clip holes 112 are provided on the first component 110. The line connecting the three clips 162 forms a triangle. In this way, when the annular base 160 and the first component 110 are assembled, the reliability of the connection between the two can be ensured. Of course, the number of clips 162 can also be two, four, etc., and the number can be adjusted according to specific design requirements.
[0082] Optionally, a positioning portion 163 is also provided on the annular base 160, and at the same time, a positioning hole cooperating with the positioning portion 163 is provided on the first component 110. In this way, when assembling the annular base 160 and the first component 110, the positioning portion 163 is inserted into the positioning hole for positioning, and then connected to the card hole 112 through the buckle 162.
[0083] It should be understood that in other embodiments, the annular base 160 and the first component 110 may also be connected by screws.
[0084] like Figure 8 and Figure 17 As shown, the annular base 160 further protrudes and extends toward one side of the accommodating cavity 1101 to form a positioning groove 161. A positioning post 134 is provided on the second compensating element 130. The positioning groove 161 and the inner wall of the installation cavity 1221 form a positioning cavity 1611, and the positioning post 134 is inserted into the positioning cavity 1611. Through the cooperation between the positioning post 134 and the positioning groove 161 of the annular base 160, the second compensating element 130 is radially restricted and positioned in the X and Z directions after being assembled with the first compensating element 120, preventing the second compensating element 130 from rotating when the fixing member 121 rotates.
[0085] For example, the positioning pillar 134 is not limited to being cylindrical, and may also be a prism or square pillar structure.
[0086] Combine Figure 10 、 Figure 11 、 Figure 23 and Figure 24As shown, in the above embodiment, the fastener 122 is further provided with a clearance hole 1223 for the positioning groove 161 and the positioning post 134 to pass through. Thus, under the action of the clearance hole 1223 and the positioning post 134, when the fastener 122 is assembled into the accommodating cavity 1101 of the first component 110, it can only rotate within the accommodating cavity 1101 by a preset angle, so that the tolerance compensator 100 and the second component 200 reach the preset position first.
[0087] See also Figure 16 Optionally, a third type of thread structure 111 is provided on the inner wall of the accommodating cavity 1101 of the first component 110, and a fourth type of thread structure 1224 is provided on the outer wall of the fastener 122 to cooperate with the third type of thread structure 111. Y-axis adjustment is achieved by screwing the third type of thread structure 111 of the first component 110 and the fourth type of thread structure 1224 of the fastener 122 into engagement, thereby compensating for Y-axis tolerances.
[0088] For example, the third type of thread structure 111 may be a spiral groove, and the fourth type of thread structure 1224 may be a spiral protrusion. It is understandable that the third type of thread structure 111 may also be a spiral protrusion, and the fourth type of thread structure 1224 may be a spiral groove.
[0089] like Figure 8 、 Figure 9 and Figure 15 As shown, in any of the above embodiments, the side of the clamping member 123 facing the through hole 1222 is provided with an elastic support piece 1233, and the elastic support piece 1233 abuts against the fastener 122. Specifically, the elastic support piece 1233 abuts against the cavity wall of the installation cavity 1221 having the through hole 1222.
[0090] In this way, when the locking member 124 rotates to a preset angle under the action of the fixing member 121 and the clamping member 123, the fixing screw continues to rotate to compress and deform the elastic support piece 1233 on the clamping member 123, thereby finally locking and fixing the first component 110 and the second component 200.
[0091] Furthermore, the end of the elastic support piece 1233 away from the locking member 124 is tilted in a direction away from the center line of the through hole 1222, which facilitates the deformation of the elastic support piece 1233 and thus facilitates deformation in the Y direction.
[0092] In any of the above embodiments, illustratively, the elastic adjustment portion 131 is formed by continuously bending the spring piece 1311 around the outer circumference of the cavity 132, so as to realize elastic deformation of the elastic adjustment portion 131 along the radial direction of the installation cavity 1221, thereby realizing deformation in the X direction and the Z direction.
[0093] like Figure 12 and Figure 18 As shown, in any of the above embodiments having the locking clip 1241, the locking clip 1241 has a guide bevel 12411 at one end away from the connecting post 1242. The provision of the guide bevel 12411 allows the locking member 124 to have a larger radial tolerance when it is assembled with the connecting hole 201 of the second component 200, thereby facilitating the locking clip 1241 of the locking member 124 to pass through the connecting hole 201.
[0094] Furthermore, in a direction perpendicular to the axis of the connecting column 1242 , the cross-section of the locking clamp 1241 is any one of a polygon, a strip, a cross or an ellipse.
[0095] For example, in this embodiment, the cross section of the locking clamp 1241 is exemplified as a square, but is not limited thereto, and may also be a triangle, a strip, a cross, or an ellipse.
[0096] An embodiment of the present application also provides an assembly component, which includes a first component 110, a second component 200 and the tolerance compensator 100 described in any of the above embodiments, wherein the tolerance compensator 100 is arranged on the first component 110, and the tolerance compensator 100 is used to fasten the first component 110 and the second component 200.
[0097] For example, the assembly assembly is described using a concealed door handle and a door sheet metal as an example. First component 110 is the concealed door handle, and second component 200 is the door sheet metal. The tolerance compensator 100 is pre-installed on the concealed door handle. Thus, when first component 110 is assembled onto second component 200, the fixing member 121 is rotated, and the locking member 124, under the action of the fixing member 121 and the engaging member 123, rotates to a preset angle to lock the second component 200 in an offset manner. The fixing member 121 and the locking member 124 are then threadedly engaged and rotated, driving the locking member 124 to move along its axis, thereby locking and securing the concealed door handle and the door sheet metal. Simultaneously, radial error compensation is achieved under the action of the elastic adjustment portion 131 of the second compensation element 130. Ultimately, the components to be assembled are locked and secured, achieving automatic compensation for the components to be assembled.
