[0025] See also Figures 1 to 7 , the utility model provides a technical solution:

[0026] A vehicle-mounted bicycle rack license plate structure comprises a clamping frame 1, the front end of the clamping frame 1 is provided with an elastic clamping assembly for clamping the license plate, the rear side of the clamping frame 1 is elastically lifted and installed with a clamping block 3, a lifting and lowering groove is provided through the clamping frame 1, the upper end of the clamping block 3 is provided with a downwardly folded and bent flange, the flange extends along the lifting and lowering groove to the front end of the clamping frame 1, and the front end of the clamping frame 1 is provided with a mounting groove 4 for mounting the license plate, the flange extends along the lifting and lowering groove into the mounting groove 4 and fastens the clamping license plate, the elastic clamping assembly comprises the clamping block 3, a clamping beam 5 and a side frame 6, a pair of side frames 6 are symmetrically provided on the left and right sides of the rear side of the clamping frame 1, a limiting seat 23 for limiting the descending height of the clamping block 3 is provided on the side frame 6, a first spring 17 is pressed between the lower end of the clamping block 3 and the limiting seat 23, and a pair of clamping blocks 3 distributed on the left and right are connected at both ends of the clamping beam 5.

[0027] The positioning installation of the license plate is achieved by setting the installation groove 4, and then the elastic installation of the block 3 is achieved by using the first spring 17. The pair of blocks 3 connected by the clamping beam 5 can realize the convenient adjustment and synchronous movement of the pair of blocks 3 distributed on the left and right. The side frame 6 and the limit seat 23 are used to limit the lower end position of the block 3 to prevent it from falling off. Before the license plate is installed, the clamping beam 3 is pulled to move the flange on the block 3 upward to facilitate the installation of the license plate. After installation, under the reset elastic force of the first spring 17, the flange is pressed onto the upper end of the license plate to achieve the purpose of fixing the license plate.

[0028] The rear side of the clamping frame 1 is rotatably mounted on the vehicle frame 7, and the first rotating arm 9 and the second rotating arm 10 are rotatably mounted on the rear side of the clamping frame 1 in parallel and at intervals. The other ends of the first rotating arm 9 and the second rotating arm 10 are both rotatably mounted on the vehicle frame 7. One ends of the first rotating arm 9 and the second rotating arm 10 are rotatably mounted on the clamping frame 1 through the fourth hinge seat 22 and the second hinge seat 11 respectively, and the other ends of the first rotating arm 9 and the second rotating arm 10 are rotatably mounted on the vehicle frame 7 through the first hinge seat 8 and the third hinge seat 18 respectively. The first hinge seat 8, the fourth hinge seat 22, the third hinge seat 18 and the second hinge seat 11 are distributed in sequence from left to right.

[0029] By setting four sets of hinge seats, the first rotating arm 9 and the second rotating arm 10 are rotatably installed, and then when they need to be folded and stored, the first rotating arm 9 and the second rotating arm 10 are rotated upward along the frame 7, so that the clamping frame 1 is in a vertical state at the front end of the frame 7, and at this time, the length of the clamping frame 1 at the upper end of the frame 7 is greater than the length at the lower end;

[0030] When the first rotating arm 9 and the second rotating arm 10 rotate downward along the frame 7, the length of the clamping frame 1 at the lower end of the frame 7 is greater than the length at the upper end, so that the extension direction of the clamping frame 1 after rotation can be adjusted in both directions according to the folding direction of the bicycle frame 7, which is suitable for the folding storage of the bicycle and further reduces the occupied space after storage.

[0031] The frame 7 is provided with a connecting piece for fixing the first rotating arm 9 and the second rotating arm 10, and the connecting piece includes a limit pin rod 14. A stepped socket 20 is provided on the frame 7. The limit pin rod 14 is elastically inserted in the stepped socket 20. A positioning socket 19 is provided at a position corresponding to the first rotating arm 9 and the stepped socket 20. The end of the limit pin rod 14 is inserted in the positioning socket 19. An elliptical block is provided in the middle section of the limit pin rod 14. An elliptical hole is provided on the inner wall of one end of the stepped socket 20 close to the positioning socket 19. A limit cover is provided at the other end of the stepped socket 20. The limit pin rod 14 is inserted in the stepped socket 20. An elastic piece pressed between the limit cover and the elliptical block is sleeved on the limit pin rod 14. The elliptical block on the limit pin rod 14 can be slidably inserted along the elliptical hole.

[0032] The elastic installation of the limit pin 14 is realized by setting an elastic member, and then the limit pin 14 is used to be inserted into the positioning hole 19 to realize the limiting fixation of the first rotating arm 9. The elastic installation of the limit pin 14 allows it to maintain elastic insertion into the positioning hole 19 to avoid falling off. When it needs to be folded and stored, the limit pin 14 is pulled outward so that the elliptical block extends to the outside of the front end of the elliptical hole, and then the limit pin 14 is rotated so that the elliptical block and the elliptical hole are misaligned and pressed together, thereby achieving the purpose of maintaining the position of the limit pin 14.

[0033] The connecting part also includes a limiting slider 13. The upper end of the frame 7 is provided with a slide groove extending to the upper ends of the second rotating arm 10 and the first rotating arm 9. The upper end of the slide groove is provided with a fixed sealing plate 12. The limiting slider 13 is elastically slidably installed in the slide groove. One side of the limiting slider 13 is provided with a side block 21 extending to the outside of the slide groove and fitting the upper end surfaces of the second rotating arm 10 and the first rotating arm 9. A second spring 15 is pressed between the limiting slider 13 and the inner wall of the slide groove. The upper end of the slide groove is blocked on the fixed sealing plate 12, and a long groove for accommodating the positioning sliding of the limiting slider 13 is provided on the fixed sealing plate 12. The extension direction of the long groove is the same as the compression direction of the second spring 15.

[0034] The second spring 15 is provided to realize the elastic installation of the limit slider 13, and then under the elastic pressing of the second spring 15, the side block 21 extends to the upper ends of the first rotating arm 9 and the second rotating arm 10, so as to achieve the purpose of limiting the rotation angle. When folding and storing, the limit slider 13 is moved to squeeze the second spring 15 so that the side block 21 extends into the slide groove, which facilitates the rotation and folding of the first rotating arm 9 and the second rotating arm 10.

[0035] Working principle: First, before installing the license plate, pull the clamping beam 3 to move the flange on the clamping block 3 upward to facilitate the installation of the license plate. After installation, under the reset elastic force of the first spring 17, the flange is pressed against the upper end of the license plate to achieve the purpose of fixing the license plate.

[0036] At this time, the limiting pin 14 is used to be inserted into the positioning hole 19 to achieve the limiting fixation of the first rotating arm 9. Under the elastic pressing of the second spring 15, the side block 21 extends to the upper ends of the first rotating arm 9 and the second rotating arm 10, thereby achieving the purpose of limiting the rotation angle and ensuring the stable installation of the clamping frame 1 on the frame 7.

[0037] When folding and storage are required, the limit pin 14 is pulled outward so that the elliptical block extends to the outside of the front end of the elliptical hole, and then the limit pin 14 is rotated so that the elliptical block and the elliptical hole are misaligned and pressed together, thereby achieving the purpose of maintaining the position of the limit pin 14, and the limit slider 13 is moved to squeeze the second spring 15 so that the side block 21 extends into the slide groove, thereby facilitating the rotation and folding of the first rotating arm 9 and the second rotating arm 10.

[0038] The first rotating arm 9 and the second rotating arm 10 rotate upward along the frame 7, so that the clamping frame 1 is in a vertical state at the front end of the frame 7, and at this time, the length of the clamping frame 1 at the upper end of the frame 7 is greater than the length at the lower end; when the first rotating arm 9 and the second rotating arm 10 rotate downward along the frame 7, the length of the clamping frame 1 at the lower end of the frame 7 is greater than the length at the upper end, so that the extension direction of the clamping frame 1 after rotation can be adjusted in both directions according to the folding direction of the frame 7 of the bicycle, which is suitable for the folding storage of the bicycle and further reduces the occupied space after storage.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
