Description

Technical Field

[0001] This utility model relates to the field of electric tricycle technology, specifically to a rotatable carriage frame for an electric tricycle. Background Technology

[0002] The rotating chassis of the electric tricycle achieves the rotation function of the chassis through a specific rotating connection structure and adjustment components, which facilitates the loading and unloading of goods. The core of the rotating chassis is the "rotating connection component between the chassis and the frame". These parts have relative friction and are the core objects of lubrication and maintenance.

[0003] However, the current method of adding lubricating oil is basically done manually, and users often forget to add lubricating oil. They only add it when reminded by maintenance personnel during maintenance. Infrequent lubrication will lead to a deterioration in the rotation of the carriage and frame, and even damage to various parts due to friction. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Please see Figures 1-5The present invention provides the following technical solution:

[0030] The electric tricycle has a rotatable chassis frame, including a body 1, a frame 2 provided on the side of the body 1, and a rotating mechanism provided inside the frame 2. The rotating mechanism includes a mounting bracket 4 fixedly installed inside the frame 2, and a self-lubricating mechanism is provided inside the mounting bracket 4.

[0031] The self-lubricating mechanism includes an extension plate 10 fixedly connected to the top of the mounting frame 4. An oil storage tank 12 is provided inside the extension plate 10. A press pump body 13 is slidably installed at the opening at the bottom of the oil storage tank 12. An elastic element 14 is provided between the top of the press pump body 13 and the inner wall of the oil storage tank 12. An oil extraction pipe 15 is provided inside the elastic element 14. The rotation mechanism can realize the rotation of the carriage 3, which is convenient for loading and unloading goods. The self-lubricating mechanism can automatically lubricate the key friction parts during the rotation process, eliminating the need for frequent manual addition of lubricating oil, reducing component wear caused by insufficient lubrication, and extending the service life of the device.

[0032] The inlet of the oil suction pipe 15 is located at the connection between the elastic element 14 and the press pump body 13 and inside the oil storage tank 12. The outlet of the oil suction pipe 15 is located at the bottom of the press pump body 13. The oil suction pipe 15 is the channel for lubricating oil transmission, which can extract the lubricating oil in the oil storage tank 12 and ensure that the lubricating oil can accurately reach the friction area.

[0033] The rotating mechanism specifically includes a driven gear 8 that is rotatably installed inside the mounting bracket 4. A pressing block 9 is fixedly connected to the top of the driven gear 8. The driven gear 8 is a transmission component that drives the carriage 3 to rotate under the drive of the driving gear 7.

[0034] Both the pressing block 9 and the pressing pump body 13 are trapezoidal in shape. The upper bottom of the pressing block 9 and the upper bottom of the pressing pump body 13 are close to each other and cooperate with each other. The trapezoidal design allows the pressing block 9 to squeeze the pressing pump body 13 when it rotates, so that the lubricating oil can be sprayed out, realizing the self-lubricating effect of the self-lubricating mechanism.

[0035] When in use, when it is necessary to rotate the carriage 3, start the drive motor 6. The drive motor 6 will drive the drive gear 7 to rotate. Since the drive gear 7 meshes with the driven gear 8, the driven gear 8 will also rotate, thereby driving the carriage 3 to rotate, which facilitates the loading and unloading of goods.

[0036] During the rotation of the driven gear 8, the pressing block 9 at its top rotates accordingly. The pressing block 9 is trapezoidal and cooperates with the pressing pump body 13, which is also trapezoidal, to squeeze the pressing pump body 13. After the pressing pump body 13 is squeezed, the elastic element 14 is also compressed. The oil extraction pipe 15 draws lubricating oil from the oil reservoir 12 and sprays it onto the connection between the driven gear 8 and the driving gear 7 to lubricate the key components. When the pressing block 9 moves away from the pressing pump body 13 with the rotation of the driven gear 8, the elastic element 14 will restore its deformation and push the pressing pump body 13 back to its initial position, waiting for the next squeeze. This cycle achieves the effect of automatic lubrication. At the same time, the multiple ball bearings 11 installed at the top of the mounting bracket 4 can not only support the carriage 3, but also reduce the friction between the carriage 3 and the mounting bracket 4, playing an auxiliary role to ensure the smooth rotation of the carriage 3.

[0037] Example 2

[0038] Please see Figures 1-5 The present invention provides the following technical solution:

[0039] The rotating mechanism also includes a sub-frame 5 fixedly connected to one end of the mounting frame 4. A drive motor 6 is fixedly installed at the bottom of the sub-frame 5. A drive gear 7 is provided at the output end of the drive motor 6. The drive motor 6 can drive the drive gear 7 to rotate. By meshing with the driven gear 8, it drives the carriage 3 to rotate. It is the drive component of the rotating mechanism.

[0040] The drive gear 7 is installed inside the sub-frame 5 and rotates through it. The connection between the mounting frame 4 and the sub-frame 5 is hollow. The drive gear 7 meshes with the driven gear 8, and the drive gear 7 transmits power to the driven gear 8. Since the number of teeth of the drive gear 7 is less than that of the driven gear 8 (i.e., the drive gear 7 is smaller than the driven gear 8), the two form a speed reduction transmission structure. The speed reduction transmission can increase the output torque. This structure is suitable for equipment with high torque but low speed operation. It is very suitable for providing rotational power to the carriage 3, thereby ensuring the stability and safety of the cargo loaded in the carriage 3 when rotating.

[0041] The carriage 3 is fixedly installed on the top of the driven gear 8. The carriage 3 is rotatably installed with the frame 2 through the driven gear 8. The carriage 3 rotates by the action of the driven gear 8 to realize functions such as loading and unloading of goods.

[0042] Multiple ball bearings 11 are rotatably mounted inside the top of the mounting bracket 4. The surface of the ball bearings 11 on the outer side of the mounting bracket 4 contacts the bottom of the carriage 3. The ball bearings 11 can not only support the carriage 3, but also reduce the friction between the carriage 3 and the mounting bracket 4, thus playing an auxiliary role in ensuring the smooth rotation of the carriage 3.

[0043] Unlike Embodiment 1, the rotating mechanism provides the rotational power source for the carriage 3, enabling functions such as loading and unloading of goods. At the same time, the ball bearings 11 play an auxiliary role, which can not only support the carriage 3, but also reduce the friction between the carriage 3 and the mounting frame 4, ensuring the smooth rotation of the carriage 3.

[0044] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
