The terms "mounting", "connecting", "connected" should be broadly understood, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium; can be internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0023] The present application will be further described in detail below with reference to the drawings and examples.

[0024] Reference Figs. 1 to 4 The embodiments of the present application provide an angle-adjustable lower ear structure, comprising a motorcycle rear frame 1, the outer side of the motorcycle rear frame 1 is sleeved with a second sleeve 5, the top of the second sleeve 5 is fixedly installed with a storage box mounting plate 3, the bottom of the storage box mounting plate 3 is provided with an adjusting assembly 2, the adjusting assembly 2 comprises a connecting block 22, the connecting block 22 is hinged at the bottom of the storage box mounting plate 3, the bottom of the connecting block 22 is fixedly installed with a first cross plate 23, the bottom of the first cross plate 23 is fixedly installed with a damper 26, the bottom of the damper 26 is fixedly installed with a second cross plate 24, the first cross plate 23 and the second cross plate 24 are fixedly installed with a spring 25, the spring 25 is sleeved outside the damper 26;

[0025] The bottom of the storage box mounting plate 3 is attached to the top of the motorcycle rear carrier 1, and the inside of the storage box mounting plate 3 is provided with a mounting groove 4; the adjusting assembly 2 further comprises an external block 29, the bottom of the second horizontal plate 24 is rotationally connected with a screw rod 27, the screw rod 27 is screwed through the inside of the external block 29; the bottom of the motorcycle rear carrier 1 is fixedly installed with a bottom frame 21, the outside of the bottom frame 21 is sleeved with a first sleeve 210, and the external block 29 is fixedly installed on the side of the first sleeve 210; the outside of the bottom frame 21 is fixedly installed with two limiting rings 211, and the two limiting rings 211 are attached to the two sides of the first sleeve 210 respectively; the bottom of the screw rod 27 is fixedly installed with a knob 28, and the knob 28 is located below the external block 29;

[0026] In the actual installation process in the embodiment, first, the second sleeve 5 is sleeved on the outside of the motorcycle rear carrier 1 to ensure stable installation of the second sleeve 5; then the storage box mounting plate 3 is installed and fixed with the storage box through the mounting groove 4 at the bottom of the storage box mounting plate 3;

[0027] When it is necessary to adjust the installation angle of the storage box, the user can hold the knob 28 with hand and rotate the knob 28 clockwise or counterclockwise, because the screw rod 27 is screwed with the external block 29, the rotation of the knob 28 will drive the screw rod 27 to move up and down in the external block 29; the movement of the screw rod 27 will push or pull the second horizontal plate 24, and then drive the first horizontal plate 23 and the connecting block 22 to move through the damper 26 and the spring 25, so that the storage box mounting plate 3 rotates around the connecting block 22 hinge point, and the adjustment of the installation angle of the storage box is realized;

[0028] In the process of driving the motorcycle, when encountering road bumps, the impact force received by the storage box will be transmitted to the adjusting assembly 2 through the storage box mounting plate 3; at this time, the spring 25 will be elastically deformed to absorb part of the impact force, and at the same time, the damper 26 will consume the energy generated by the impact force to slow down the rebound speed of the spring 25, thereby effectively reducing the vibration of the storage box and protecting the goods and connecting structure in the storage box;

[0029] In different use scenarios, such as when it is necessary to increase the inclination angle of the storage box to facilitate taking and placing goods, the knob 28 can be rotated according to the above adjustment mode, so that the screw rod 27 moves upward to push the second horizontal plate 24 upward, thereby increasing the inclination angle of the storage box mounting plate 3; when it is necessary to reduce the height of the storage box to reduce wind resistance or improve the overall stability of the motorcycle, the knob 28 is reversely rotated to make the screw rod 27 move downward to drive the second horizontal plate 24 to descend, thereby reducing the height and inclination angle of the storage box mounting plate 3;

[0030] During long-term use, the sliding of the first sleeve 210 on the bottom frame 21 is always kept within a reasonable range due to the action of the limiting ring 211, ensuring the structural stability of the adjusting assembly 2 and preventing loosening of the connection or damage to the structure due to excessive sliding.

[0031] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0032] Working principle: When the angle-adjustable lower ear structure is working, the second sleeve 5 is sleeved outside the motorcycle rear frame 1, and the storage box mounting plate 3 is fixed by using the mounting groove 4 at the bottom of the storage box mounting plate 3; when the angle is adjusted, the knob 28 is rotated to drive the screw rod 27 to move up and down in the external block 29, thereby pushing or pulling the second horizontal plate 24, and the first horizontal plate 23 and the connecting block 22 are driven to move through the damper 26 and the spring 25, so that the storage box mounting plate 3 rotates around the hinge point to realize angle adjustment; when the motorcycle is running and jolted, the spring 25 and the damper 26 jointly act to reduce the vibration of the storage box; and the limiting ring 211 outside the bottom frame 21 limits the sliding range of the first sleeve 210, thereby ensuring the structural stability of the adjusting assembly 2.

[0033] It should be noted that, in the present document, the terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed or inherent to such a process, method, article or device.

[0034] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
