DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 A quick-release battery box suitable for an electric motorcycle includes a battery box installed in the electric motorcycle. The battery box is in a rectangular shape as a whole and is suitable for an electric motorcycle with a rectangular mounting groove. The battery box includes a housing 1, a top cover 2 and a base 9. The front and rear ends of the upper end of the top cover 2 are symmetrically provided with plug-in grooves 7 for plugging in a connecting plate 4. The lower end of the top cover 2 is provided with a first through hole 8 that is connected to the plug-in groove 7 and is used to plug in a round rod 5. The round rod 5 is fixedly connected to the lower end of the connecting plate 4, wherein the plug-in groove 7 needs to meet the requirements of plug-in groove 7 when the connecting plate 4 is plugged into it. The sides of the groove 7 are all fitted to prevent dust from entering the first through hole 8 through the gap, and further prevent dust from entering the shell 1. The inner side of the shell 1 is penetrated from top to bottom with a third through hole 20 for plugging in the round rod 5. The base 9 is provided with a second through hole 10 for plugging in the round rod 5. The base 9 is provided with a locking mechanism for temporarily fixing the round rod 5, that is, when the round rod 5 is plugged in, it first passes through the first through hole 8, then passes through the third through hole 20, and finally passes through the second through hole 10, wherein the length of the round rod 5 makes the lower end of the round rod 5 flush with the lower end surface of the base 9.

[0024] In this embodiment, through the coordinated arrangement of the round rod 5, the shell 1, the top cover 2, the base 9 and the locking mechanism, the shell 1, the top cover 2 and the base 9 can be locked together. When the locking mechanism releases the lock on the round rod 5, the battery box can be disassembled more conveniently and quickly.

[0025] Specific, combined Figure 3 and Figure 4 As shown, in order to enhance the structural strength of the base 9, a plurality of rows of reinforcing plates 11 are fixedly connected to the lower end of the base 9 along the left-right direction, and a plurality of guide rods 12 are fixedly connected to the lower end of the base 9 along the front-back direction, and the reinforcing plates 11 and the guide rods 12 are distributed in a grid shape.

[0026] Specific, combined Figure 5 As shown, the round rod 5 passes through one end of the base 9 and is provided with a slot 6 on the side facing the center surface of the base 9, wherein the outer side surface of the round rod 5 does not contact the inner side surface of the second through hole 10, and a certain insertion space is left, that is, the direction and position of the slot 6 are the same.

[0027] Specific, combined Figure 3 and Figure 4 As shown, the locking mechanism includes a transmission plate 16 slidably connected to the guide rod 12 near one end of the round rod 5, so that the transmission plate 16 can contact the round rod 5. In order to achieve the locking of the round rod 5, an extension plate is provided on the side of the transmission plate 16 facing the round rod 5, and the extension plate can be plugged into the plug-in space. A circular groove 17 is provided at the end of the extension plate facing the round rod 5. The diameter of the circular groove 17 is consistent with the diameter of the round rod 5. A plug-in plate 18 that can be plugged into the slot 6 is fixedly connected to the middle of the circular groove 17. At this time, when the plug-in plate 18 is plugged into the slot 6, the circular groove 17 will fit on the outer side of the round rod 5, thereby ensuring the stability of the round rod 5.

[0028] Specific, combined Figure 3 and Figure 4 As shown, the middle part of the reinforcing plate 11 is rotatably connected to a round shaft 13 through a bearing, both ends of the round shaft 13 are set as threaded sections 14, and the transmission plate 16 is threadedly connected to the threaded sections 14, so that when the round shaft 13 is rotated, the transmission plate 16 can be driven to move.

[0029] Specifically, in order to reduce the collision of the battery box when it is placed in the electric motorcycle, a shock-absorbing pad 19 is detachably provided at the lower end of the base 9, and the shock-absorbing pad 19 is fixed to the lower end of the base 9 by bolts or screws.

[0030] Specifically, in order to facilitate the rotation of the circular shaft 13 , an anti-slip sleeve 15 is fixedly connected to the middle of the circular shaft 13 to increase the friction between the finger and the circular shaft 13 .

[0031] Specifically, in order to facilitate lifting the battery box, a handle 3 is provided at the upper end of the top cover 2 .

[0032] Installation method: First, the staff passes the round rod 5 through the first through hole 8, then through the third through hole 20, and finally through the second through hole 10. At this time, the upper and lower ends of the shell 1 are respectively attached to the top cover 2 and the base 9. At this time, by rotating the anti-slip sleeve 15, the round shaft 13 is driven to rotate, and then the threaded section 14 drives the transmission plate 16 to move, so that the transmission plate 16 drives the extension plate to be plugged into the plug-in space, and finally the plug-in plate 18 is inserted into the slot 6 to complete the locking of the round rod 5, and then the shock-absorbing pad 19 is fixed to the bottom of the base 9 by bolts to complete the overall installation of the battery box. When disassembling, reverse the anti-slip sleeve 15 to drive the round shaft 13 to reverse, and the plug-in plate 18 is disengaged from the slot 6. At this time, the round rod 5 can be pulled out to achieve the separation of the shell 1, the top cover 2 and the base 9.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the description and drawings of the present invention shall be included in the protection scope of the present invention.
