[0040] like Figure 2A-2D As shown, the bracket 101 includes a mounting portion 208 and a pair of fixing portions 290. The mounting portion 208 is substantially in the shape of an oval plate and has a first side 231 and a second side 232. Figure 2A and Figure 2B The second side 232 of the mounting portion 208 is shown. Figure 2C and Figure 2D A first side 231 of the mounting portion 208 is shown. The mounting portion 208 has a pair of nut assembly connecting portions 218 and 219, which are connected to the nut assemblies 102 and 103 respectively. A pair of fixing portions 290 are disposed between the nut assembly connecting portions 218 and 219, extending from the second side 232 of the bracket 101. The pair of fixing portions 290 protrude from the second side 232 of the bracket 101. Each fixing portion 290 has a vertical portion 293, and the vertical portion 293 has a protrusion 292 at a distal end, and the protrusion 292 can enter a corresponding hole of the mounting site to connect the bracket 101 to the mounting site.

[0041] The nut assembly connection parts 218 and 219 are symmetrical structures. The specific structure is described below by taking the nut assembly connection part 218 as an example. The nut assembly connection part 218 includes a mounting channel 211 and a bracket connection part 215. The mounting channel 211 extends in a direction from the first side 231 to the second side 232 and penetrates the first side 231 and the second side 232. The nut assembly 102 can enter the mounting channel 211. The bracket connection part 215 is connected to the inner wall 224 of the mounting channel 211. The bracket connection part 215 is used to cooperate with the nut assembly 102.

[0042] The mounting channel 211 includes a first portion 225 and a second portion 226, the first portion 225 and the second portion 226 are separated, and the first portion 225 is located on one side of the second portion 226. The first portion 225 includes a substantially circular central portion 280, and a first recess 281, a second recess 282, a third recess 283, and a fourth recess 284 arranged around the central portion 280. The first recess 281, the second recess 282, the third recess 283, and the fourth recess 284 are recessed from the central portion 280 along the radial direction toward the direction away from the center C of the central portion 280. The first recess 281, the center C of the central portion 280, and the second portion 226 are located on the same straight line. A platform portion 222 is provided in the first recess 281. The platform portion 222 is located in the first recess 281 and is connected to one end of the first recess 281 away from the center C of the central portion 280. Near the first recess 281, the platform portion 222 is lower than the surface of the second side 232 of the mounting portion 208, thereby forming a step with the second side 232 of the mounting portion 208. The platform portion 222 is located inside the first portion 225, and the platform portion 222 does not exceed the surface of the first side 231 and the second side 232 in the extending direction of the mounting channel 211.

[0043] The second recess 282 includes a pair of side walls 273 and 274 arranged along the circumferential direction of the central portion 280. An elastic arm 272 is provided in the second recess 282. The elastic arm 272 extends from the side wall 273 toward the side wall 274. The distal end of the elastic arm 272 is a free end and has a spacing with the side wall 274. The elastic arm 272 is located inside the second recess 282 and is lower than the surface of the second side 232 of the mounting portion 208. A limiting portion 271 is provided at the distal end of the elastic arm 272. The limiting portion 271 extends from the distal end of the elastic arm 272 along the extension direction of the mounting channel 211 toward the second side 232 of the mounting portion 208 and exceeds the surface of the second side 232. That is, the extension direction of the limiting portion 271 is substantially perpendicular to the surface of the second side 232 of the mounting portion 208.

[0044] The third recess 283 and the fourth recess 284 have the same structure as the second recess 282. The third recess 283 and the fourth recess 284 are also provided with the same elastic arm 272 and the limiting portion 271, which will not be described again. The second recess 282, the third recess 283 and the fourth recess 284 are distributed along the circumferential direction, and there is a gap between each adjacent recess. The elastic arm 272 of each recess extends around the central portion 280.

[0045] The second part 226 is substantially square and has a pair of first inner side walls 261 and 262 disposed opposite to each other, and a pair of second inner side walls 263 and 264 disposed opposite to each other. The first inner side wall 261 is located on a side of the second part 226 away from the central part 280, the first inner side wall 262 is located on a side of the second part 226 close to the central part 280, and the second inner side walls 263 and 264 are connected to both ends of the first inner side walls 261 and 262, respectively. A receiving portion 221 is provided in the second part 226, and the receiving portion 221 includes a pair of retaining arms 241 and 242. The retaining arms 241 and 242 extend from the first inner side wall 261 toward the first inner side wall 262, and have a spacing therebetween. The retaining arms 241 and 242 have a spacing therebetween, and have a spacing therebetween with the second inner side walls 263 and 264, respectively. The distal ends of the retaining arms 241 and 242 can be bent in a direction away from each other. The distal ends of the retaining arms 241 and 242 have retaining arm protrusions 238 and 239, respectively, and the retaining arm protrusions 238 and 239 extend toward each other. The retaining arms 241 and 242 are both located inside the second portion 226 and do not exceed the surfaces of the first side 231 and the second side 232 of the mounting portion 208. That is, the receiving portion 221 is located in the mounting channel 211.

[0046] In the present application, the bracket connecting portion 215 includes a platform portion 222 and a receiving portion 221 , and the receiving portion 221 and the platform portion 222 are used to connect the nut assembly 102 .

[0047] The first side 231 of the bracket 101 has a recess 265, which is arranged around the mounting channel 211 and is recessed from the surface of the first side 231 toward the second side 232. The shape of the recess 265 matches the shape of the mounting nut flange 401.

[0048] In another embodiment of the present application, the first portion 225 and the second portion 226 of the installation channel 211 are interconnected structures without being separated.

[0049] In another embodiment of the present application, the platform portion 222 and the receiving portion 221 are not on the same line as the center of the central portion 280 , and the platform portion 222 and the receiving portion 221 are arranged around the central portion 280 with a distance therebetween.

[0050] In yet another embodiment of the present application, the number of the second recessed portions 282 and the corresponding elastic arms and positioning portions is not limited to three and can be set to any number as required.

[0051] Figure 3A for Figure 1B A three-dimensional view of the nut assembly. Figure 3B for Figure 1B Exploded view of the nut assembly. Figure 1B The nut components 102 and 103 have the same structure. Figure 3A and Figure 3B The structure of the nut assembly is described by taking the nut assembly 102 as an example. Figure 3A and Figure 3B As shown, the nut assembly 102 includes a mounting nut 301, an adjusting nut 302, and a bushing 303. The adjusting nut 302 is disposed in the mounting nut 301 and can rotate relative to the mounting nut 301 to adjust the length of the nut assembly 102. The bushing 303 is disposed in the adjusting nut 302 and can move with the adjusting nut 302. The bushing 303 is cylindrical and has a bushing channel 385. The bushing 303 is used to increase the friction between the adjusting nut 302 and the fastening assembly (such as a screw). The nut assembly 102 extends in the axial direction and has a central axis 320.

[0052] Figure 4A yes Figure 3B A three-dimensional view of the mounting nut. Figure 4B yes Figure 4A Another perspective view of the installation nut. Figure 4C yes Figure 4A Bottom view of the installation nut. Figure 4A-4C The structure of the mounting nut is shown.

[0053] like Figure 4A-4C As shown, the mounting nut 301 includes a mounting nut flange portion 401, a mounting nut barrel portion 402 and a nut connecting portion 425. The mounting nut barrel portion 402 extends in the direction of the central axis 320 of the nut assembly 102, and has a first end 411 and a second end 412. The mounting nut barrel portion 402 is roughly hollow cylindrical, thereby surrounding a nut receiving channel 415. The nut receiving channel 415 can receive the adjusting nut 302. The inner wall of the mounting nut barrel portion 402 has an internal thread 427, which can cooperate with the external thread of the adjusting nut 302. The mounting nut flange portion 401 extends outward from the second end 412 of the mounting nut barrel portion 402 along the radial direction of the nut assembly. The outer contour of the mounting nut flange portion 401 is roughly a square with an arc chamfer, so that the mounting nut flange portion 401 is in an anti-rotation shape. The shape of the mounting nut flange portion 401 matches the shape of the recess 265 of the bracket 101 , so that the mounting nut flange portion 401 can enter the recess 265 to limit the mounting nut 301 from rotating relative to the bracket 101 .

[0054] The mounting nut flange portion 401 has a first side 431 and a second side 432 disposed opposite to each other, and a third side 433 and a fourth side 434 disposed opposite to each other. The nut connecting portion 425 is connected to the first side 431 and the second side 432.

[0055] The nut connecting portion 425 includes a leg portion 421 and a hook portion 422. The leg portion 421 is connected to the first side 431 and extends toward the first end 411 of the mounting nut barrel portion 402 along the axial direction of the mounting nut barrel portion 402. The leg portion 421 includes a rod portion 443 and a protrusion 430, wherein the rod portion 443 is connected to the first end 411, and the protrusion 430 is connected to the rod portion 443 and is located at the distal end of the leg portion 421. The protrusion 430 extends from both sides of the rod portion 443 toward the third side 433 and the fourth side 434, thereby forming a pair of steps 478 and 479 between the two sides of the rod portion 443. The steps 478 and 479 can cooperate with the retaining arm protrusions 238 and 239 of the receiving portion 221 to retain the protrusion 430 between the retaining arms 241 and 242.

[0056] The hook portion 422 is connected to the second side 432 and extends along the axial direction of the mounting nut barrel portion 402 toward the first end 411 of the mounting nut barrel portion 402. The hook portion 422 includes a rod portion 444 and a claw portion 440, wherein the rod portion 444 is connected to the second end 412, and the claw portion 440 is connected to the rod portion 444 and is located at the distal end of the hook portion 422. The claw portion 440 extends from the end of the rod portion 444 along the radial direction of the nut assembly 102 toward a direction away from the central axis of the nut assembly, so that a step 445 is formed between the claw portion 440 and the rod portion 444. The step 445 can be matched with the platform portion 222.

[0057] Figure 5 yes Figure 1B A three-dimensional view of the adjusting nut. Figure 5 As shown, the adjusting nut includes an adjusting nut flange portion 511 and an adjusting nut barrel portion 512, and the adjusting nut flange portion 511 extends from one end of the adjusting nut barrel portion 512 along the radial direction of the nut assembly 102 in a direction away from the central axis of the nut assembly 102. The outer surface of the adjusting nut barrel portion 512 is provided with an external thread 525, which can cooperate with the internal thread 427 of the mounting nut barrel portion 402, so that the adjusting nut 302 can rotate relative to the mounting nut 301 to change the length of the nut assembly 102. The adjusting nut flange portion 511 has a plurality of notches 508, and the plurality of notches 508 are formed by being recessed inwardly (i.e., toward the central axis of the nut assembly) from the edge of the adjusting nut flange portion 511. Thus, the outer profile of the adjusting nut flange portion 511 is a gear-like shape. The plurality of notches 508 are used to cooperate with the limiting portion 271. When the adjusting nut 302 and the mounting nut 301 are in the closest position, the limiting portion 271 can enter at least one of the plurality of notches 508 to limit the adjusting nut 302 from rotating relative to the mounting nut 301 .

[0058] Fig. 6A yes Figure 3B The mounting nuts in Figure 1B A three-dimensional diagram of the bracket in FIG. Figure 6B yes Figure 3B The mounting nuts in Figure 1B Another perspective view of the bracket in the figure. In order to facilitate the connection between the mounting nut and the bracket, Fig. 6A and Figure 6B In the figure, the adjusting nut and the bushing are hidden. When the mounting nut 301 is connected to the bracket 101, the mounting nut 301 is inserted into the mounting channel 211 from the first side 231 of the mounting portion 208 of the bracket 101. When installing, the claw portion 440 of the hook portion 422 of the mounting nut 301 is first pressed against the platform portion 222 of the bracket 101, and then the mounting nut barrel portion 402 is aligned with the first portion 225 of the mounting channel 211, and the leg portion 421 of the mounting nut 301 is aligned with the second portion 226 of the mounting channel 211. The leg 421 of the mounting nut 301 is pressed so that the protrusion 430 of the leg 421 of the mounting nut 301 enters the gap between the retaining arms 241 and 242. The protrusion 430 squeezes the retaining arm protrusions 238 and 239 so that the distal ends of the retaining arms 241 and 242 are bent away from each other until the protrusion 430 passes through the retaining arm protrusions 238 and 239. The distal ends of the retaining arms 241 and 242 are deformed again, and the steps of the protrusion 430 abut against the retaining arm protrusions 238 and 239, so that the mounting nut 301 is retained in the mounting channel 211.

[0059] exist Fig. 6A and Figure 6B The mounting nut is connected to the bracket in place. Fig. 6A and Figure 6B As shown, the mounting nut barrel 402 enters the first portion 225 of the mounting channel 211, and the size of the mounting nut barrel 402 matches the size of the center portion 280 of the first portion 225 to limit the movement of the mounting nut 301 relative to the bracket 101 along the radial direction of the nut assembly. The claw portion 440 of the hook portion 422 of the mounting nut 301 abuts against the platform portion 222 of the bracket 101 to limit the movement of the claw portion 440 relative to the bracket 101 along the axial direction of the nut assembly. The protrusion 430 of the leg portion 421 abuts against the retaining arm protrusions 238 and 239 to limit the movement of the protrusion 430 relative to the bracket 101 along the axial direction of the nut assembly. The mounting nut flange portion 401 enters the recess 265 of the bracket 101. The mounting nut flange portion 401 entering the recess 265 of the bracket 101 is a non-circular anti-rotation shape, so that the mounting nut 301 cannot rotate relative to the bracket. In this embodiment, the mounting nut 301 and the bracket 101 are detachable structures.

[0060] In the present application, the connection structure between the mounting nut 301 and the bracket 101 is both arranged in the mounting channel 211 , thereby saving space in the axial direction of the nut assembly.

[0061] In one embodiment of the present application, the bracket connecting portion 215 of the mounting nut 301 includes a pair of legs, and the bracket includes a pair of receiving portions. The pair of legs cooperates with the pair of receiving portions to connect the mounting nut 301 to the bracket 101, and the hook portion and the platform portion are no longer provided.

[0062] Figure 7 yes Figure 1B A three-dimensional diagram of a nut assembly and a bracket. Figure 7 As shown, the nut assembly 102 is mounted on the bracket 101. The mounting nut 301 and the adjusting nut 302 are at the closest position, that is, the length of the nut assembly 102 is the shortest. At this time, at least one limiting portion 271 of the bracket 101 enters into at least one notch 508 of the adjusting nut 302. The cooperation between the limiting portion 271 and the notch 508 can limit the rotation of the mounting nut 301 relative to the adjusting nut 302 in the direction of loosening, so as to prevent the mounting nut 301 and the adjusting nut 302 from loosening or disengaging due to vibration or other reasons during transportation.

[0063] Figure 8 yes Figure 1A A three-dimensional diagram of the tolerance compensation component, the first component, the second component and the fastening bolts. Figure 8 As shown, the tolerance compensation assembly 100 includes a bracket 101, and a pair of nut assemblies 102 and 103 mounted on the bracket 101. The fastening bolts include screws 811 and 812, and nuts 821 and 822. The tolerance compensation assembly 100 cooperates with the fastening bolts to connect the first component 801 and the second component 802, and at the same time provide support between the first component 801 and the second component 802 to prevent the first component 801 and the second component 802 from being crushed.

[0064] The first component 801 includes a pair of bolt mounting holes 841 and 842. The second component 802 includes a pair of screw mounting holes 851 and 852, and a pair of bracket mounting holes 861 and 862.

Fig. 9C It is a schematic diagram of the fastening connection between the first component and the second component.

[0066] like Fig.9A As shown, when connecting the first component 801 with the second component 802 , first align the pair of fixing portions 290 of the tolerance compensation assembly 100 with the bracket mounting holes 861 and 862 of the second component to facilitate installing the bracket 101 into the second component 802 .

[0067] When the pair of fixing portions 290 of the tolerance compensation assembly 100 enter the bracket mounting holes 861 and 862 of the second component, the bushing channels 385 of the nut assemblies 102 and 103 of the tolerance compensation assembly 100 are respectively aligned with the bolt mounting holes 851 and 842 of the second component 802 .

[0068] like Fig. 9B As shown, the screw rods 811 and 812 are passed through the bolt mounting holes 841 and 842 of the first component 801, and the screw rods 811 and 812 are inserted into the bushing channels 385 of the nut assemblies 102 and 103. Since there is a large friction between the screw rods 811 and 812 and the bushing 303, the rotating screw rods 811 and 812 can drive the adjusting nut 302 to rotate together through the bushing 303. The adjusting nut 302 rotates with the rotation of the screw rods 811 and 812, thereby moving toward the second component 802 until it abuts against the lower surface of the second component 802.

[0069] like Fig. 9C As shown, the operator continues to rotate the screw rods 811 and 812, and the adjustment nut 302 is blocked by the second component 802 and cannot be rotated further. The operator then applies force to the screw rods 811 and 812 to overcome the friction between the bushing 303 and the screw rods 811 and 812, so that the screw rods 811 and 812 pass through the screw rod mounting holes 851 and 852 of the second component 802. The operator then sleeves the nuts 821 and 822 on the screw rods 811 and 812, and rotates the nuts 821 and 822 to a suitable position to connect the first component 801 and the second component 802.

[0070] Nut assemblies 102 and 103 are disposed between the first component 801 and the second component 802 , so as to provide support for the first component 801 and the second component 802 and prevent the first component 801 or the second component 802 from being deformed when the nuts 821 and 822 are rotated.

[0071] In one application of the present application, the first component is a body sheet metal of a vehicle, and the second component is a rear wing of the vehicle.

[0072] In the present application, the nut assembly and the bracket of the tolerance compensation assembly are detachable structures, which is convenient for manufacturing. The connection structure between the nut assembly and the bracket is arranged inside the installation channel, so that the dimension of the tolerance compensation assembly in the axial direction of the nut assembly is small, which is suitable for a narrow installation space. The bracket in the present application also has a limiter, which can prevent the nut assembly from loosening during transportation.
