Description

Technical Field

[0001] The utility model relates to the field of electric motorcycles, in particular to a battery compartment assembly and a battery-swap electric motorcycle. Background Art

[0002] Power batteries are used to provide electrical energy to the motor, thereby providing forward propulsion for the vehicle, and are the primary energy storage unit for electric motorcycles. To avoid stopping to recharge, some electric motorcycles use battery swapping technology, increasing range by replacing batteries. For straddle-style electric motorcycles, accessing and removing the battery is difficult due to the high body of the motorcycle. The battery must first be moved out horizontally and then lifted vertically. Heavier batteries are particularly laborious to extract, and when parked in a narrow space, removing the battery horizontally becomes difficult, making the operation extremely inconvenient.

[0003] Therefore, there is an urgent need for a battery compartment assembly and a battery-swap electric motorcycle that can easily remove and place batteries to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of the utility model is to provide a battery compartment assembly that is convenient for taking out and placing batteries.

[0005] Another object of the present invention is to provide a battery-swappable electric motorcycle with a removable battery.

[0006] To achieve the above-mentioned purpose, the battery compartment assembly provided by the present invention is used for a battery-swap electric motorcycle, including a fixed compartment shell and a rotating compartment shell. The fixed compartment shell is surrounded by the rotating compartment shell, and the rotating compartment shell is rotatably installed on the fixed compartment shell. The rotating compartment shell can be rotated and adjusted relative to the fixed compartment shell. The rotating compartment shell and the fixed compartment shell enclose a battery placement cavity with a variable size and an open top for storing power batteries. The rotating compartment shell has at least a closed state that is completely contained in the fixed compartment shell and an open state that is laterally tilted away from the fixed compartment shell. When the rotating compartment shell is rotated relative to the fixed compartment shell, it switches from the closed state to the open state, so that the volume of the battery placement cavity gradually increases, and the power battery installed in the battery placement cavity synchronously follows the rotation of the rotating compartment shell and finally tilts away from the fixed compartment shell.

[0007] Preferably, the bottom of the rotating bin shell is connected to the bottom of the fixed bin shell by a hinge, the rotating bin shell in the closed state is arranged upright, and the rotating bin shell in the open state is arranged at a 45° tilt.

[0008] Preferably, the bottom of the rotating housing has a rotating base plate for supporting the battery, and the rotating base plate allows the battery supported by it to rotate synchronously with the rotating housing.

[0009] Preferably, the rotating bin shell includes a rotating front plate, a rotating rear plate and a rotating side plate. The rotating front plate is installed on the front side of the rotating side plate, the rotating rear plate is installed on the rear side of the rotating side plate, and the rotating bottom plate is installed on the bottom side of the rotating side plate. The rotating front plate, the rotating rear plate, the rotating bottom plate and the rotating side plates together enclose a battery placement space with openings on both sides.

[0010] Preferably, the fixed bin shell includes a fixed front plate, a fixed rear plate, a fixed bottom plate and a central side plate, the fixed front plate is installed on the front side of the central side plate, the fixed rear plate is installed on the rear side of the central side plate, and the fixed bottom plate is installed on the bottom side of the central side plate. The fixed front plate, the fixed rear plate, the fixed bottom plate and the central side plate together enclose a accommodating space with openings on both sides. The rotating bin shell is arranged in the accommodating space, and the rotating bin shell gradually tilts out of the accommodating space during the process of switching from a closed state to an open state.

[0011] Preferably, the battery compartment assembly of the present invention also includes a gas spring, one end of which is hinged to the fixed front plate, and the other end of the gas spring is fixed to the rotating side plate. The gas spring always has a tendency to drive the rotating compartment shell to rotate and switch from a closed state to an open state.

[0012] Preferably, the two battery compartment assemblies are connected back to back along the left and right directions and the two battery placement cavities are separated by a central side plate.

[0013] Preferably, a first mounting bracket is installed on the front side of the fixed front plate, and a second mounting bracket is installed on the rear side of the fixed rear plate. The battery compartment assembly is fixedly mounted on the battery-swap electric motorcycle by means of the first mounting bracket and the second mounting bracket.

[0014] To achieve the second objective, the battery-swap electric motorcycle provided by the present invention comprises a vehicle body, a power battery, and the battery compartment assembly. The battery compartment assembly is fixedly mounted on the vehicle body, and the power battery is mounted in the battery compartment.

[0015] Preferably, the vehicle body is provided with a locking device, which locks the rotating bin shell in the closed state to keep the rotating bin shell in the closed state.

[0016] Compared with the prior art, the battery-swap electric motorcycle provided by the present invention includes a battery compartment assembly, which includes a fixed compartment shell and a rotating compartment shell. When the power battery needs to be removed, the rotating compartment shell is operated to be in an open state, and the power battery synchronously rotates with the rotating compartment shell and eventually deviates from the fixed compartment shell. At this time, the power battery is placed in a tilted state, and the battery placement cavity is gradually opened to its maximum volume. It is understandable that since the power battery is placed at an angle and the battery placement cavity is opened to its maximum, there is less obstruction when removing the power battery, and the power battery can be easily removed. Moreover, the power battery can be lifted up from the battery placement cavity at an angle, and the operation of extracting the power battery becomes labor-saving and convenient. Since the rotating compartment shell is only tilted away from the fixed compartment shell and does not occupy much space to the outside, the power battery can be extracted after opening the rotating compartment shell in a narrow space, thereby increasing the applicable scenarios of the battery-swap electric motorcycle. Furthermore, the power battery can be directly taken in and out by hand at one time without segmented operation, which simplifies the process of taking in and out the power battery and facilitates operation.

[0026] In order to explain the technical content and structural features of the present invention in detail, the following is a further description in conjunction with the embodiments 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 motorcycle body 200, and a power battery 300. The battery compartment assembly 100 is fixedly mounted to the motorcycle body 200, and the power battery 300 is housed within the battery compartment assembly 100. The power battery provides electrical energy to the motor, providing forward propulsion for the motorcycle body 200, thereby driving the motorcycle body 200.

[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 needs, the battery compartment assembly 100 can be installed in other positions of the vehicle body 200. Of course, the battery-swap electric motorcycle 1000 of the present invention can also adopt a scooter-type body layout.

[0029] Advantageously, the battery-swap electric motorcycle 1000 of the present invention is equipped with two battery compartment assemblies 100, which can accommodate two power batteries 300, providing sufficient energy to supply the vehicle body 200 and improving the endurance of the battery-swap electric motorcycle 1000. In addition, a decorative panel 400 is 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, preventing the battery compartment assembly 100 from being directly exposed. This makes the appearance of the battery-swap electric motorcycle 100 more harmonious and unified, and the overall style 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. In other words, 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 shell 10 (as shown) Figure 5 、 Figure 6 、 Figure 8 and Figure 9As the rotating housing 20 rotates relative to the fixed housing 10, it switches from a closed state to an open state, gradually increasing the volume of the battery compartment. This also causes the power battery 300 installed in the battery compartment to rotate synchronously with the rotating housing 20, ultimately tilting away from the fixed housing 10. When the rotating housing 20 is in the closed state, it is completely contained within the fixed housing 10 and is not exposed to the outside. At this point, the external volume of the battery compartment assembly 100 is minimized, and the power battery 300 is placed in a generally upright position.

[0031] When the power battery 300 needs to be removed, the rotating housing 20 is operated to be in the open state, and the power battery 300 rotates synchronously with the rotating housing 20 and eventually deviates from the fixed housing 10. At this time, the power battery 300 is placed in a tilted state, and the battery placement cavity is gradually opened to its maximum volume. It is understandable that because the power battery 300 is placed at an angle and the battery placement cavity is opened to its maximum, there is less obstruction when removing the power battery 300, and the power battery 300 can be easily removed. Moreover, the power battery 300 can be lifted from the battery placement cavity at an angle, making the operation of extracting the power battery 300 labor-saving and convenient. Since the rotating housing 20 is only tilted away from the fixed housing 10 and does not occupy much space to the outside, the power battery 300 can be extracted after opening the rotating housing 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 in and out at one time by hand without the need for segmented operation, which simplifies the process of taking in and out the power battery 300 and facilitates operation.

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

[0033] Preferably, the fixed housing 10 and the rotating housing 20 are constructed in a frame-like structure, made of iron or steel plates by stamping, welding, or other methods, to provide sufficient strength to protect the power battery 300. However, the fixed housing 10 and the rotating housing 20 may also be constructed in a plastic frame structure or other form.

[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 rotated. The rotating housing 20 in the closed state is arranged upright, and the power battery 300 is also upright at this time (please refer to Figure 9 The battery compartment assembly 100 on the left side of the middle). The rotating compartment housing 20 in the open state is tilted at 45 degrees, and the power battery 300 is also tilted at 45 degrees (please refer to Figure 9(The battery compartment assembly is shown on the right side of the center panel.) In other words, the shape of the power battery 300 corresponds exactly to the shape of the rotating housing 20. When the power battery 300 is tilted at 45°, access and placement are more labor-saving and convenient. Of course, depending on actual application needs, the rotating housing 20 in the open state can be tilted at other angles, such as 50°, 60°, etc.

[0035] like Figure 7 、 Figure 8 and Figure 9 As shown, to ensure a one-to-one correspondence between the shape of the power battery 300 and the rotating housing 20, a rotating base plate 21 is provided at the bottom of the rotating housing 20 for supporting the power battery 300. The rotating base plate 21 causes the supported power battery 300 to rotate synchronously with the rotating housing 20. As part of the rotating housing 20, the rotating base plate 21 rotates in unison with the rotating housing 20. After the rotating base plate 21 supports the power battery 300, the power battery 300 can also rotate synchronously with the rotating housing 20. When the rotating housing 20 is rotated so that it tilts away from the fixed housing 10, the power battery 300 also tilts away from 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 plates 24 collectively enclose a battery storage space 25 with openings on both sides. The power battery 300 is stored in the battery storage space 25. The rotating housing 20 of the embodiment provided by the present invention is generally a square frame 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 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 a top opening). The rotating housing 20 is provided in the receiving space 15, and the rotating housing 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 space for accommodating the rotating housing 20. The fixed housing 10 and the rotating housing 20 serve to protect and accommodate 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. The locking device locks the rotating housing 20 in the closed state to keep the rotating housing 20 in the closed state. The locking device locks the rotating housing 20 by hooking, snapping, pulling, 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, such as 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 from a closed state to an open state. After the locking device is unlocked, the gas spring 40 pushes the rotating side plate 24, driving 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. Moreover, due to the travel limit of the gas spring 40, the rotating compartment shell 20 stops when it rotates to a certain angle, maintaining the opening angle, such as the 45° provided in the embodiment of the present invention, which makes it 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 a 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 can be taken in and out from the left and right sides of the battery-swap electric motorcycle 1000, respectively, to increase the convenience of operation. The power batteries 300 loaded into the two battery compartment assemblies 100 are separated by the central side plate 14. 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 bracket 16 is installed on the front side of the fixed front plate 11, and a second mounting bracket 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 bracket 16 and the second mounting bracket 17. Specifically, the battery compartment assembly 100 is fixedly installed on the vehicle body 200 with the help of the first mounting bracket 16 and the second mounting bracket 17.

[0042] Figure 3 and Figure 4, 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.

[0043] The above disclosure is only a preferred embodiment of the present invention and cannot be used to limit the scope of the rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope covered by the present invention.
