[0002] Existing motorcycles generally include a body and a front portion, and a rear bracket is generally provided on the rear side of the body so that a trunk can be installed on the rear bracket for storage.

[0003] Conventionally, there are four screw holes at the bottom of the trunk of a motorcycle, two of which are located on the rear side and are symmetrical on the left and right, and two of which are located on the front side and are symmetrical on the left and right. Correspondingly, two matching rods are provided on the rear bracket, one in front and one in the back, and each matching rod has two symmetrical through-holes. Each through-hole is in the shape of a long strip extending left and right, so that when the screw hole and the corresponding through-hole are aligned, the trunk can be installed by passing the bolt through the through-hole from below and matching with the screw hole thread.

[0004] However, the above installation method has high requirements on the relative position of the screw holes and the through holes. Although the long strip through holes allow installation with a certain deviation on the left and right, if there is a deviation in the front and back positions of the screw holes and the through holes, installation will be impossible, resulting in low installation adaptability.

It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention. The specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and the specific features do not naturally and directly limit the scope of implementation of the present invention. The conventional selections and replacements made by those skilled in the art under the guidance of the present invention should be deemed to be within the scope of protection claimed by the present invention.

[0024] like Figure 1-Figure 7 As shown, the utility model discloses a motorcycle with an adjustable rear bracket, including a body 91 and a front 92. A U-shaped rear bracket 1 is provided on the rear side of the body 91, and the rear bracket 1 is detachably fixed to the body 91 by means of bolts. A first support rod 2 and a second support rod 3 are fixedly provided on the rear bracket 1. The first support rod 2 is located behind the second support rod 3, and the first support rod 2 and the second support rod 3 are both extended in the left and right directions. In addition, two left-right symmetrical first through-holes 21 are provided on the first support rod 2, and two left-right symmetrical mounting positions 31 are provided on the second support rod 3. A rotating frame 4 is rotatably mounted on each mounting position 31, and each rotating frame 4 is provided with a second through-hole 431. Each second through-hole 431 is in the shape of a long strip extending along the length direction of the corresponding rotating frame 4.

[0025] Therefore, the two screw holes on the rear side of the bottom of the trunk that need to be installed are respectively aligned with the two first through-holes 21 on the first support rod 2 and fixed with bolts. Afterwards, the second through-holes 431 and the corresponding screw holes on the front side of the bottom of the trunk can be adjusted by rotating the rotating frame 4, and fixed with bolts after alignment. Among them, since the second through-holes 431 are long holes and the rotating frame 4 can be rotated relative to the second support rod 3, the corresponding screw holes can be aligned within the surface area formed by the movement trajectory of the second through-holes 431 to ensure absolute positioning and prevent the inability to align the installation due to the front-to-back deviation of the screw holes and the second through-holes 431 on the trunk.

[0026] Preferably, each of the first perforations 21 in this embodiment is in the shape of a long strip extending left and right, so that the long strip-shaped first perforations 21 can more effectively adapt to the two screw holes on the rear side of the trunk, preventing the inability to align the two first perforations 21 at the same time due to the spacing deviation between the two screw holes on the rear side of the trunk.

[0027] In other embodiments, one of the first through-holes 21 is in the shape of a long strip extending left and right, and the other first through-hole 21 is in the shape of a circular hole, so that the first through-hole 21 through the circular hole and one of the screw holes of the trunk can be positioned, and the other long strip-shaped first through-hole 21 can effectively adapt to the other screw hole. After the installation is completed, the overall positioning is more precise.

[0028] Among them, in this embodiment, a first supporting plane 22 is provided above the first support rod 2, a second supporting plane 33 is provided above the second support rod 3, and a third supporting plane 11 is provided above the rear bracket 1. The third supporting plane 11 is U-shaped, and the first supporting plane 22, the second supporting plane 33, and the third supporting plane 11 are coplanar, so that the trunk is placed on the rear bracket 1, and the trunk is supported by the first supporting plane 22, the second supporting plane 33, and the third supporting plane 11 to improve the stability of the support.

[0029] Preferably, each of the mounting positions 31 in this embodiment is located below the second support rod 3, and each of the mounting positions 31 is provided with a mounting post 32 integrally formed with the second support rod 3, and each of the mounting posts 32 is provided with a mounting screw hole 321 that is open downward, and each of the rotating frames 4 is provided with a mounting through-hole 411 that is sleeved on the outer periphery of the corresponding mounting post 32, and a mounting bolt 5 is provided between each of the rotating frames 4 and the mounting post 32 for limiting the rotating frame 4 from separating from the mounting post 32, and each of the mounting bolts 5 passes through the corresponding mounting through-hole 411 and is threadedly engaged with the corresponding mounting screw hole 321. Therefore, the rotating frame 4 adopts the mounting through-hole 411 to be sleeved on the outer periphery of the mounting post 32, and then the mounting bolt 5 passes through the mounting through-hole 411 and is threadedly connected with the mounting screw hole 321 to achieve limited installation, making installation convenient.

[0030] Preferably, the lower end of the mounting column 32 in this embodiment is integrally formed with a plug-in ring 322, and the outer diameter of the plug-in ring 322 is adapted to the inner wall diameter of the mounting through-hole 411 and is smaller than the outer diameter of the mounting column 32, so that the mounting through-hole 411 fits into the outer periphery of the plug-in ring 322, and the upper end is limited upward by the mounting column 32, while the lower end is limited downward by the mounting bolt 5, and the rotation is smoother while being limited up and down, so that the rotation of the rotating frame 4 can be achieved without loosening the mounting bolt 5.

[0031] Specifically, each of the rotating frames 4 in this embodiment is stepped (Z-shaped), and each of the rotating frames 4 includes a first mounting portion 41, a lifting portion 42 and a second mounting portion 43 connected in sequence, each of the first mounting portions 41 is matched with the corresponding mounting column 32, each of the second through-holes 431 is arranged on the corresponding second mounting portion 43, and a fitting plane 432 coplanar with the second supporting plane 33 is arranged above each of the second mounting portions 43, and a reinforcing rib 44 is arranged between each of the second mounting portions 43 and the corresponding lifting portion 42.

[0032] Therefore, 1. The lifting portion 42 is provided to connect the first mounting portion 41 below that needs to cooperate with the mounting column 32 and the second mounting portion 43 above that is used to cooperate with the trunk, so that the second mounting portion 43 is closer to the trunk and can be more stably connected to the trunk by abutting against the trunk through the fitting plane 432; 2. The reinforcing rib 44 is provided to increase the connection strength between the second mounting portion 43 and the lifting portion 42, thereby improving the stability of the connection between the rotating frame 4 and the trunk and preventing it from moving.

[0033] Specifically, the first support rod 2 in this embodiment includes a first mounting section 23, a first lifting section 24 symmetrically arranged at both ends of the first mounting section 23, and a second mounting section 25. Each of the second mounting sections 25 is located below the rear bracket 1 and is fixedly connected to the rear bracket 1 respectively. Each first lifting section 24 is used to connect the first mounting section 23 with the corresponding second mounting section 25 as an integral whole. The first supporting plane 22 and each first through-hole 21 are arranged on the first mounting section 23; the second support rod 3 includes a third mounting section 34, a second lifting section 35 symmetrically arranged at both ends of the third mounting section 34, and a fourth mounting section 36. Each of the fourth mounting sections 36 is located below the rear bracket 1 and is fixedly connected to the rear bracket 1 respectively. Each second lifting section 35 is used to connect the third mounting section 34 with the corresponding fourth mounting section 36 as an integral whole. The second supporting plane 33 and each mounting position 31 are arranged on the third mounting section 34.

[0034] Specifically, screw holes can be set on the rear bracket 1, and through holes can be set on the second mounting section 25 and the fourth mounting section 36, so that bolts can be passed through the through holes and matched with the screw holes to achieve fixed installation of the first support rod 2 and the second support rod 3 on the rear bracket 1.

[0035] After the first support rod 2 and the second support rod 3 are installed in the trunk, the second mounting section 25 and the fourth mounting section 36 installed below the rear bracket 1 will be restricted by the trunk and cannot move downward. Therefore, even if the first support rod 2 and the second support rod 3 are disconnected from the rear bracket 1, the trunk will not fall.

[0036] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
