Description

Technical Field

[0001] This utility model relates to the field of three-wheeled motorcycle technology, and in particular to an electric three-wheeled motorcycle tail box with an anti-sway structure. Background Technology

[0002] An electric tricycle is a three-wheeled vehicle that uses an electric drive system. It is typically used for short-distance transportation, urban freight, or personal commuting. Electric systems are generally more environmentally friendly, producing less noise and emitting no harmful exhaust fumes.

[0003] Chinese Patent Publication No. CN205203241U discloses a cargo box for a three-wheeled motorcycle, comprising a cargo box floor, two side doors, a front door, and a rear door; the cargo box floor, two side doors, front door, and rear door form the body of the three-wheeled motorcycle; the two side doors and the rear door are hinged to the cargo box floor; the side doors are characterized in that: each side door includes a rectangular frame composed of two vertical beams, an upper crossbeam, and a lower crossbeam; horizontal bars and main ribs are arranged horizontally and sequentially inside the rectangular frame; several guardrails are arranged vertically between the upper crossbeam and the horizontal bars; and several vertical ribs are arranged vertically between the main ribs and the lower crossbeam. This utility model provides a three-wheeled motorcycle cargo box with an aesthetically pleasing, robust, and durable structure.

[0004] The above-mentioned device increases the rigidity of the trailer by setting additional reinforcement structures. However, since the trailer and the frame are designed separately, an anti-sway structure should be added during the design process. Otherwise, the trailer will sway synchronously with the three-wheeled motorcycle during operation. Such repeated swaying will increase the wear and aging speed of the connection and affect the service life of the device. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an electric tricycle tail box with an anti-sway structure, which aims to improve the problem mentioned in the prior art that "the tail box of the split tricycle will shake synchronously with the tricycle during operation, resulting in wear and aging at the connection point".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electric three-wheeled motorcycle tail box with an anti-sway structure, comprising a vehicle body, a bottom plate fixedly connected to the top of the vehicle body, a back plate fixedly connected to the left end of the bottom plate, a trailer box installed at the top of the bottom plate, a support plate fixedly connected to the top of the back plate, a one-way threaded rod rotatably connected through the right end of the support plate, a moving block rotatably connected to the left end of the one-way threaded rod, a reinforcing component provided at the left end of the moving block, and a connecting component provided at the top of the trailer box.

[0007] As a further description of the above technical solution:

[0008] The connecting component includes a first mounting groove, which is located at the top of the trailer, and a second mounting groove is located at the bottom of the base plate. The inner wall of the second mounting groove is provided with a rubber clip.

[0009] As a further description of the above technical solution:

[0010] Bolts are inserted into the inner wall of the first mounting groove, and nuts are inserted into the inner wall of the second mounting groove. The bolts and nuts are compatible.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 An embodiment of this utility model provides: an electric tricycle tail box with an anti-sway structure, including a vehicle body 1 for carrying the overall device, a bottom plate 2 for supporting the tail box 4 fixedly connected to the top of the vehicle body 1, a back plate 3 for preventing the tail box 4 from shaking randomly fixedly connected to the left end of the bottom plate 2, a tail box 4 for placing goods installed on the top of the bottom plate 2, a support plate 8 for supporting the reinforcing component 7 fixedly connected to the top of the back plate 3, a one-way threaded rod 5 for driving the moving block 6 to move left and right through and rotatably connected to the right end of the support plate 8, a moving block 6 for driving the fixed block 10 to move rotatably connected to the left end of the one-way threaded rod 5, a reinforcing component 7 for fixing the tail box 4 to prevent it from shaking randomly provided on the left end of the moving block 6, and a connecting component 9 for connecting the tail box 4 and the bottom plate 2 provided on the top of the tail box 4.

[0031] Reference Figure 1 and Figure 2The left end of the moving block 6 is fixedly connected to a fixed block 10 for moving the extrusion block 11. The left end of the fixed block 10 is fixedly connected to an extrusion block 11 for directly contacting the inner wall of the trailer 4. The extrusion block 11 is made of rubber, has elastic deformation capability and a relatively rough surface, which can increase the static friction force after contacting the inner wall of the trailer 4. The front end of the fixed block 10 is rotatably connected to a bidirectional threaded rod 74 for moving the slider 71 left and right. The reinforcing component 7 includes a slider 71 for moving the support block 73 left and right. The right end of the slider 71 is slidably connected to the left end of the moving block 6. The slider 71 and the bidirectional threaded rod 74 are threadedly connected. When the bidirectional threaded rod 74 rotates, it drives the slider 71 to move inward or outward through the thread.

[0032] Reference Figure 2 The left end of the slider 71 is rotatably connected to a roller 72 for the operator to rotate the bidirectional threaded rod 74. The front end of the slider 71 is fixedly connected to a support block 73 for fixing the inner wall of the trailer 4. The outer wall of the bidirectional threaded rod 74 is fixedly connected to a rotating wheel 75 for the operator to move the slider 71. The top of the moving block 6 is provided with a groove 76 for the operator to rotate the rotating wheel 75. The moving block 6 is slidably connected to the bottom end of the support plate 8. The moving block 6 can be moved horizontally left and right by rotating the unidirectional threaded rod 5.

[0033] Reference Figure 1 and Figure 3 The connecting component 9 includes a first mounting groove 91 for accommodating bolts 95, which is located at the top of the trailer 4. The bottom of the base plate 2 has a second mounting groove 92 for accommodating nuts 94. The first mounting groove 91 and the second mounting groove 92 are identical in shape and are both elongated. This design allows for normal installation even if the left and right positions of the two grooves are not perfectly aligned. The inner wall of the second mounting groove 92 is provided with rubber clips 93 to support the nuts 94 and prevent them from falling off. The inner wall of the first mounting groove 91 is fitted with bolts 95 for connecting the base plate 2 and the trailer 4. The inner wall of the second mounting groove 92 is fitted with nuts 94 for matching bolts 95. Nuts 94 are hexagonal, and the diagonal length of nuts 94 is less than the width of the second mounting groove 92. This prevents nuts 94 from rotating after entering the second mounting groove 92, thus ensuring that bolts 95 and nuts 94 are compatible.

[0034] Working principle: When using the trailer box 4, first rotate the one-way threaded rod 5 to move the fixing block 10 to the left. The fixing block 10 will move the pressing block 11 to the left to press the inner wall of the trailer box 4, so that the left end of the trailer box 4 is close to the right end of the back plate 3. Then, rotate the wheel 75 to drive the two-way threaded rod 74 to rotate. When the two-way threaded rod 74 rotates, it will force the slider 71 to move outward until the outer wall of the support block 73 tightly presses the inner wall of the trailer box 4, so that the trailer box 4 is completely fixed and cannot move. Then, the bolts 95 and nuts 94 can be installed.

[0035] When installing bolt 95 and nut 94, bolt 95 can be inserted into the inner wall of mounting groove 2 92. The top of rubber block 93 will block the bottom of bolt 95 to prevent bolt 95 from falling down. Then bolt 95 can be inserted into mounting groove 1 91 to start installation. During the installation process, bolt 95 will be restricted from rotating by the inner wall of mounting groove 2 92. Therefore, the operator does not need to pay too much attention to bolt 95 during installation, which is more convenient. After nut 94 and bolt 95 are installed, trailer 4 will be completely fixed to the top of base plate 2.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
