[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0023] See also Figure 1-Figure 4 The electric lifting motorcycle frame includes a fixed frame 1 and a movable frame 2 longitudinally slidably connected to the fixed frame 1. A support arm 9 is fixed to the fixed frame 1. The support arm 9 is a fixture for matching it with other components. The support arm 9 can be a tubular structure, and a plurality of mounting holes can be opened on it so that the support arm 9 can be fixedly mounted on other components, such as a rear base of a vehicle or other mounting platforms. Two support arms 9 can be arranged on the left and right.

[0024] The fixing frame 1 includes fixing frame side rods 11 on the left and right sides, and sliders 3 are fixedly installed on the inner sides of the two fixing frame side rods 11 respectively. As one option, the sliders 3 can be fixedly installed on the fixing frame side rods 11 by fasteners.

[0025] In this embodiment, the slider 3 includes a third through-hole, and the movable frame 2 includes movable frame side rods 21 on the left and right sides to match it. Sliding rods 22 are fixedly installed on the outer sides of the two movable frame side rods 21 respectively. The shape and size of the sliding rods 22 are matched with the shape and size of the third through-hole. The sliding rod 22 is inserted into the third through-hole so that the movable frame 2 and the fixed frame 1 form a sliding fit relationship.

[0026] like Figure 1 As shown, the two movable frame side rods 21 of the movable frame 2 are respectively arranged in the fixed rod side rods 11, and the movable frame 2 is laterally limited by the fixed rod side rods 11, so that it cannot move laterally and can only move longitudinally, so that the lifting action of the movable frame 2 is more stable.

[0027] In this embodiment, a driving unit 4 is fixedly installed on the top of the fixed frame 1. The driving unit can be a motor. The driving unit 4 is transmission-connected with a longitudinally arranged screw rod 5. Correspondingly, a nut 6 that matches with the screw rod 5 thread is fixedly installed on the movable frame 2. Therefore, when the driving unit 4 drives the screw rod 5 to rotate, the movable frame 2 rises and falls accordingly under the action of the nut 6 that matches with the screw rod 5. For example, when the motor rotates forward, the movable frame rises, and when the motor rotates reversely, the movable frame falls. The control switch used to control the start of the motor and the power supply of the motor can refer to the existing design.

[0028] In order to improve the stability of the movement of the screw rod 5, in this embodiment, the lower end of the screw rod 5 is rotatably configured on the positioning rod 7, and the two ends of the positioning rod 7 are respectively extended to form extension heads 71, and the extension heads 71 ​​are fixedly installed on the side rod 11 of the fixed frame to provide a fixed and stable support structure for the lower end of the screw rod 5.

[0029] like Figure 1 , Figure 2 As shown, two opposite extension heads 71 ​​may be extended from both ends of the positioning rod 7, and an opening 72 for the side rods of the movable frame to pass through is formed between the two extension heads 71 ​​as an escape space.

[0030] In this embodiment, the lower end of the movable frame 2 includes a support platform 8 for supporting a motorcycle, and a limit platform 81 for limiting the motorcycle tire is fixedly installed on the support platform 8. The limit platform 81 includes a first through hole 82 for the front end of the motorcycle tire to pass through. As one of the options, the limit platform 81 can be fixedly installed on the front end of the support platform 8.

[0031] In order to adapt to motorcycles of different sizes and models, in this embodiment, the support platform 8 also includes a limiting plate 83 for limiting the motorcycle tire. The limiting plate 83 includes a second through-hole 84 for the front end of the motorcycle tire to pass through. The setting position of the limiting plate 83 is closer to the middle position of the support platform relative to the limiting platform 8, so as to be suitable for smaller motorcycles.

[0032] In this embodiment, the limit plate 83 can be an inclined structure, which can be rotatably configured on the support platform 8. Specifically, a plurality of fixed plates 85 are fixedly installed on the support platform 8, and a plurality of through holes 86 are opened on the fixed plates 85. The positions of the through holes 86 on the two fixed plates 85 correspond to each other. A connecting shaft 87 is configured, and the corresponding through hole is selected according to actual needs. The connecting shaft 87 can be a screw, which is passed through the corresponding through hole and positioned by a nut, and the limit plate 83 is installed on the connecting shaft 87.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
