[0026] In order to explain the technical content and structural features of the present invention in detail, further description is given below in combination with the implementation modes and the accompanying drawings.

[0027] like Figure 1 As shown, the present invention discloses a battery-swap electric motorcycle 1000, comprising a battery compartment assembly 100, a vehicle body 200 and a power battery 300. The battery compartment assembly 100 is fixedly mounted on the vehicle body 200, and the power battery 300 is installed in the battery compartment assembly 100. The power battery provides electrical energy to the motor, provides forward power to the vehicle body 200, and drives the vehicle body 200 to travel.

[0028] The battery-swap electric motorcycle 1000 of the present invention adopts a straddle-type body layout, and the battery compartment assembly 100 is located below the fuel tank. Of course, according to application requirements, the battery compartment assembly 100 can be installed at other positions of other vehicle bodies 200. Of course, the battery-swap electric motorcycle 1000 of the present invention can also adopt a pedal-type body layout.

[0029] Preferably, the battery-swap electric motorcycle 1000 of the present invention is provided with two battery compartment assemblies 100, which can accommodate two power batteries 300, provide sufficient energy to supply the vehicle body 200, and improve the endurance of the battery-swap electric motorcycle 1000. In addition, a decorative panel 400 is also installed on the outside of the battery compartment assembly 100. The decorative panel 400 is consistent with the design style of other decorative parts of the vehicle body 200. The decorative panel 400 can cover the battery compartment assembly 100 to prevent the battery compartment assembly 100 from being directly exposed. The appearance of the battery-swap electric motorcycle 1000 is more harmonious and unified, and the overall style is more prominent.

[0030] like Figures 3 to 9 As shown, the battery compartment assembly 100 of the present invention includes a fixed compartment shell 10 and a rotating compartment shell 20. The fixed compartment shell 10 is surrounded by the rotating compartment shell 20, and the rotating compartment shell 20 is rotatably installed on the fixed compartment shell 10. That is, the rotating compartment shell 20 is arranged in the fixed compartment shell 10, and the rotating compartment shell 20 can rotate relative to the fixed compartment shell 10. The rotating compartment shell 20 and the fixed compartment shell 10 enclose a battery placement cavity (not shown) of variable size and open top for storing the power battery 300. The rotating compartment shell 20 has at least one closed state (such as a closed state) that is completely contained in the fixed compartment shell 10. Figure 3 , Figure 4 , Figure 7 As shown) and a sideways inclined state that is biased away from the fixed housing 10 (as shown Figure 5 , Figure 6 , Figure 8 and Fig. 9As shown). When the rotating housing shell 20 rotates relative to the fixed housing shell 10, it switches from a closed state to an open state, so that the volume of the battery placement cavity gradually increases, and the power battery 300 installed in the battery placement cavity synchronously rotates with the rotating housing shell 20 and finally tilts out of the fixed housing shell 10. When the rotating housing shell 20 is in the closed state, the rotating housing shell 20 is completely accommodated in the fixed housing shell 10, and the rotating housing shell 20 is not exposed to the outside. At this time, the volume occupied by the battery compartment assembly 100 is the smallest, and the power battery 300 is placed in a substantially upright state.

[0031] When the power battery 300 needs to be taken out, the rotating housing shell 20 is operated to be in an open state, and the power battery 300 synchronously rotates with the rotating housing shell 20 and finally deviates from the fixed housing shell 10. At this time, the power battery 300 is placed in an inclined state, and the battery placement cavity is gradually opened to the maximum volume. It is understandable that since the power battery 300 is placed at an angle and the battery placement cavity is opened to the maximum, there is less obstruction when taking out the power battery 300, and the power battery 300 can be easily taken out. Moreover, the power battery 300 can be lifted obliquely from the battery placement cavity, and the operation of extracting the power battery 300 becomes labor-saving and convenient. Since the rotating housing shell 20 is only tilted away from the fixed housing shell 10, it does not occupy much space to the outside, so the power battery 300 can be extracted after opening the rotating housing shell 20 in a narrow space, increasing the applicable scenarios of the battery-swap electric motorcycle 1000. Furthermore, the power battery 300 can be directly taken and placed by hand at one time without segmented operation, and the process of taking and placing the power battery 300 is simplified and easy to operate.

[0032] In the embodiment provided by the present invention, the power battery 300 is square, but is not limited to the square shape, and power batteries in shapes such as cylindrical shapes may also be used.

[0033] Preferably, the fixed housing 10 and the rotating housing 20 are frame-shaped structures, which are made of iron plates, steel plates, etc. by stamping, welding, etc., to increase the strength sufficiently to protect the power battery 300. However, the fixed housing 10 and the rotating housing 20 may also be in the form of a plastic frame structure.

[0034] like Figure 6 As shown, the bottom of the rotating housing 20 is connected to the bottom of the fixed housing 10 by a hinge 30, so that the rotating housing 20 and the fixed housing 10 can be rotatably installed. The rotating housing 20 in the closed state is arranged upright, and the power battery 300 is also in an upright state at this time (please refer to Fig. 9 The battery compartment assembly 100 on the left side of the middle). The rotating compartment housing 20 in the open state is arranged at a 45° tilt, and the power battery 300 is also tilted at a 45° tilt (please refer to Fig. 9In other words, the shape of the power battery 300 corresponds to the shape of the rotating housing 20. When the power battery 300 is tilted at 45°, the operation of taking and placing is more labor-saving and more convenient. Of course, according to actual application needs, the rotating housing 20 in the open state can be set to be tilted at other angles, such as 50°, 60°, etc.

[0035] like Figure 7 , Figure 8 and Fig. 9 As shown, in order to make the shape of the power battery 300 correspond to the rotating housing 20, a rotating bottom plate 21 for supporting the power battery 300 is provided at the bottom of the rotating housing 20. The rotating bottom plate 21 makes the supported power battery 300 rotate synchronously with the rotating housing 20. As a part of the rotating housing 20, the rotating bottom plate 21 rotates in accordance with the rotating housing 20. After the rotating bottom plate 21 supports the power battery 300, the power battery 300 can also rotate synchronously with the rotating housing 20. After the rotating housing 20 is rotated to tilt the rotating housing 20 out of the fixed housing 10, the power battery 300 also tilts out of the fixed housing 10.

[0036] like Figures 3 to 9 As shown, the rotating housing 20 includes a rotating front plate 22, a rotating rear plate 23 and a rotating side plate 24. The rotating front plate 22 is mounted on the front side of the rotating side plate 24, and the rotating rear plate 23 is mounted on the rear side of the rotating side plate 24. The rotating front plate 22, the rotating rear plate 23, the rotating bottom plate 21 and the rotating side plate 24 together enclose a battery placement space 25 with openings on both sides. The power battery 300 is stored in the battery placement space 25. The rotating housing 20 of the embodiment provided by the present invention is generally a square frame shell structure with openings on both sides (including the top side opening). The rotating housing 20 provides sufficient positioning and protection for the power battery 300.

[0037] like Figures 3 to 9 As shown, the fixed housing shell 10 includes a fixed front plate 11, a fixed rear plate 12, a fixed bottom plate 13 and a central side plate 14. The fixed front plate 11 is installed on the front side of the central side plate 14, the fixed rear plate 12 is installed on the rear side of the central side plate 14, and the fixed bottom plate 13 is installed on the bottom side of the central side plate 14. The fixed front plate 11, the fixed rear plate 12, the fixed bottom plate 13 and the central side plate 14 together enclose a receiving space 15 with openings on both sides (including the top opening). The rotating housing shell 20 is arranged in the receiving space 15, and the rotating housing shell 20 gradually tilts out of the receiving space 15 during the process of switching from a closed state to an open state. The receiving space 15 provides a space for receiving the rotating housing shell 20. The fixed housing shell 10 and the rotating housing shell 20 play the role of protecting and accommodating the power battery 300.

[0038] The battery-swap electric motorcycle 1000 provided by the present invention is provided with a locking device (not shown) on the vehicle body 200, and the locking device locks the rotating housing 20 in the closed state so that the rotating housing 20 remains in the closed state. The locking device locks the rotating housing 20 by hooking, snapping, pulling hooks, etc. After the locking device is unlocked, the rotating housing 20 can be operated to rotate, so that the rotating housing 20 is switched from the closed state to the open state.

[0039] In order to automatically rotate the rotating housing 20 after unlocking the locking device, the rotating housing 20 is automatically switched from the closed state to the open state. Figures 3 to 9 As shown, the battery compartment assembly 100 of the present invention also includes a gas spring 40. One end of the gas spring 40 is hinged to the fixed front plate 11, and the other end of the gas spring 40 is fixed to the rotating side plate 24. The gas spring 40 always has a tendency to drive the rotating compartment shell 20 to rotate and switch from a closed state to an open state. After the locking device is unlocked, the gas spring 40 pushes the rotating side plate 24 to drive the rotating compartment shell 20 to rotate. The rotating compartment shell 20 rotates slowly to prevent the rotating compartment shell 20 from rotating too fast and injuring the rider. In addition, due to the travel limit of the gas spring 40, the rotating compartment shell 20 stops when it rotates to a certain angle and maintains the opening angle, such as the 45° provided in the embodiment of the present invention. At this time, it is convenient for people to take out the power battery 300. The gas spring 40 adopts the existing structure.

[0040] like Figures 1 to 9 As shown, in the embodiment provided by the present invention, the two battery compartment assemblies 100 are connected back to back along the left and right directions and the two battery placement cavities are separated by the central side plate 14. The two battery compartment assemblies 100 can be loaded with two power batteries 300 to increase the power. After unlocking the locking device, the two rotating compartment shells 20 are respectively rotated outward by 45°. At this time, the power batteries 300 are respectively taken in and out from the left and right sides of the battery-swap electric motorcycle 1000, which increases the convenience of operation. The power batteries 300 loaded into the two battery compartment assemblies 100 are separated by the central side plate 14, and the two power batteries 300 are independent of each other and do not affect each other.

[0041] like Figures 1 to 9 As shown, a first mounting frame 16 is installed on the front side of the fixed front plate 11, and a second mounting frame 17 is installed on the rear side of the fixed rear plate 12. The battery compartment assembly 100 is fixedly installed on the battery-swap electric motorcycle 1000 by means of the first mounting frame 16 and the second mounting frame 17. Specifically, the battery compartment assembly 100 is fixedly installed on the vehicle body 200 with the help of the first mounting frame 16 and the second mounting frame 17.

[0042] Figure 3 and Figure 4In the figure, the direction indicated by arrow X is from left to right, the direction indicated by arrow Y is from front to back, and the direction indicated by arrow Z is from top to bottom.
