[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See Figures 1-5An axial quick-release motor mounting structure for electric off-road motorcycles, comprising a frame unit 1 and a motor unit 2.

[0021] The frame unit 1 can be made of metal, and its rear end is formed with a housing cavity 11 for housing the motor unit 2. The housing cavity 11 can be formed by two or more metal plates on the left and right sides. At the same time, motor mounting ports 12 and panel openings 13 are provided on the two metal plates on the left and right sides for pushing or pulling in the motor unit.

[0022] The motor mounting port 12 has several guide grooves 121 on its side wall. In one embodiment, the multiple guide grooves 121 are arranged circumferentially or evenly on the side wall of the motor mounting port 12, and the width of the side wall can be set to be greater than 0.5cm.

[0023] Correspondingly, a number of guide strips 21 adapted to the guide grooves 121 are formed on the outer side wall of the motor unit 2. When installing the motor unit 2, the guide strips 21 are aligned with the guide grooves 121 one by one and then pushed into the motor unit 2. As one option, the guide strips 21 are arranged circumferentially or evenly on the outer side wall of the motor unit 2.

[0024] In this embodiment, the frame unit 1 also includes a positioning plate 3, which is arranged in the accommodating cavity 11. The positioning plate 3 can be integrally formed with the frame unit or fixed on the frame unit by welding or other fixing methods.

[0025] The positioning plate 3 provides a reference position for pushing in the motor unit 2. That is, during installation, the motor unit 2 can be pushed in directly to the bottom. At this time, the inner end of the motor unit 2 abuts against the positioning plate 3, and there is no need to manually check whether the motor unit 2 is installed in place.

[0026] In this embodiment, the inner end of the motor unit 2 includes a boss 22. Correspondingly, the positioning plate 3 includes an opening slot 31 that matches the boss 22. When the motor unit 2 is pushed to the bottom, not only does the inner end wall of the motor unit 2 abut against the side wall of the positioning plate 3, but the boss 22 is also pushed into the opening slot 31 to support the inner end of the motor unit 2 through the positioning plate 3, thereby improving the support stability of the motor unit 2.

[0027] Of course, in order to make the motor unit 2 more coordinated with the frame unit 1 after assembly, the fixed position of the positioning plate 3 can be set so that when the motor unit 2 is installed in place, the outer end of the motor unit 2 is flush with the side wall of the frame unit 1 located on the side of the motor mounting port 12.

[0028] In this embodiment, a plurality of first mounting holes 23 are provided on the inner side wall of the motor unit 2. Correspondingly, a plurality of second mounting holes 32 are provided on the positioning plate 3. During installation, fasteners pass through the second mounting holes 32 and are connected to the first mounting holes 23 to position the motor unit 2 on the positioning plate 3. For example, the first mounting hole 23 is a threaded hole that is threaded to engage with the fastener.

[0029] As one option, the positioning plate 3 has at least four second mounting holes 32 on the side of the opening slot 31, and the positions of the second mounting holes 32 correspond one-to-one with the first mounting holes 23.

[0030] In this embodiment, the panel opening 13 is in fluid communication with the accommodating cavity 11, and a panel 4 that can cover the panel opening 13 is installed there. As one option, a plurality of mounting protrusions 131 are arranged on the side wall of the panel opening 13, and a plurality of third mounting holes 132 are provided on the mounting protrusions 131. A plurality of fourth mounting holes 41 corresponding to the third mounting holes 132 are provided on the panel 4. After the fastener passes through the fourth mounting hole 41, it is connected to the third mounting hole 142 to fix the panel 4 to the frame unit 1. The third mounting hole 132 is a threaded hole that is threaded to engage with the fastener.

[0031] The fasteners on the motor unit 2 and the positioning plate 3 can be tightened or loosened through other openings on the frame unit 1. Alternatively, the panel 4 can be removed first, and then the opening 13 on the panel can be used to provide the space required for tightening or loosening the fasteners. After locking the motor unit 2 onto the positioning plate 3, the panel 4 can be locked.

[0032] The motor unit 2 includes a sprocket 5. After the motor unit 2 is assembled, the chain 6 is installed onto the sprocket 5.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
