The placement slot is provided behind the seat, so that the battery assembly is provided behind the seat. When the user sits on the seat, the overall center of gravity is as centered as possible compared to the previous structure in which the battery assembly is provided under the seat. In this way, the scooter is more stable, safer, and has a lower probability of tipping over when in use. At the same time, the battery assembly is provided at the rear side of the seat and is directly placed in the placement slot. In this way, when the battery assembly is damaged and needs to be repaired or replaced, the battery assembly can be directly pulled upward to remove the battery assembly from the placement slot for repair or replacement. The seat should not affect the installation and disassembly of the battery assembly, thereby improving the convenience of battery assembly, installation, disassembly and maintenance, reducing the difficulty of operation for maintenance personnel and installers, and improving the convenience of operation. At the same time, the footrest space is also larger, and the passenger riding comfort is also stronger. Furthermore, handle grooves are respectively provided on both sides of the battery assembly, so that when installing or disassembling the battery assembly, the operator can directly grasp the handle grooves on both sides with both hands to drive the battery assembly to move for installation or disassembly.

[0039] At the same time, a first power connection position is set in the placement groove, and a second power connection position is set at the bottom of the battery assembly. When the battery assembly is installed in the placement groove, the second power connection position directly contacts or engages with the first power connection position, thereby achieving electrical connection, so that the battery assembly can provide power to the mobility scooter.

[0040] Among them, the first power connection position can be a metal contact or an elastic metal contact, and the second power connection position can also be a metal contact or an elastic metal contact. Preferably, the first power connection position is an elastic metal contact, and the second power connection position is a metal contact. In this way, after the battery assembly is loaded into the placement slot, the metal contact directly contacts and squeezes the elastic metal contact, which can ensure the stability of the electrical connection between the two. Of course, the first power connection position and the second power connection position (the first power connection position and the second power connection position are not shown in the figure) can be a metal plug and a metal slot respectively. When the battery assembly is placed in the placement slot, the metal plug is inserted into the metal slot to achieve electrical connection between the two.

[0041] See also Figures 3 to 5As shown, the battery assembly 2 includes an upper battery box 8, a lower battery box 9 and a battery (the battery is not shown in the figure), the battery is placed in the lower battery box 9, the upper battery box 8 is covered on the top of the lower battery box 9, and the upper battery box 8 and the lower battery box 9 are fixed by bolts.

[0042] In this embodiment, the lower battery box has a battery compartment 10, and the battery is directly loaded into the battery compartment. Then the upper battery box cover is closed on the lower battery box, and the upper battery box and the lower battery box are connected and fixed with bolts, that is, the battery is limited in the battery compartment so that the battery will not shake relative to the upper battery box and the lower battery box, making the three into a whole.

[0043] The left and right sides of the upper battery box and the lower battery box are respectively provided with upward concave arc surfaces, and the handle groove is formed between the arc surfaces and the side walls of the lower battery box. In this embodiment, the handle groove is directly formed by the upward concave arc surface, so there is no need to separately make the handle and the upper battery box or the lower battery box for assembly, which can reduce parts and reduce the manufacturing and assembly costs.

[0044] See also Figure 2 , 3 As shown, the outer edge of the upper battery box is arranged outside the outer edge of the lower battery box, and completely covers the top of the lower battery box. Preferably, the top outer edge of the lower battery box is arranged inside the upper battery box, so that the upper battery box completely covers the top of the lower battery box, so that when it rains, it can prevent external water from entering the battery box, playing a waterproof role.

[0045] Furthermore, in order to prevent water from accumulating and entering the lower battery box when it rains outdoors, the outer edge of the upper battery box is inclined downward from the inside to the outside; in this way, rainwater can be diverted through the inclined portion to prevent accumulation of rainwater.

[0046] The outer edge of the upper battery box is arranged below the outer bottom surface of the corresponding outer edge of the lower battery box, so that water flowing down the top surface of the upper battery box will not enter the lower battery box from the edge of the lower battery box, and the waterproof effect is better.

[0047] In order to facilitate the installation and removal of the battery assembly, the handle groove is arranged above the placement groove. In this way, when the battery assembly needs to be removed, the battery assembly can be directly lifted out from the handle groove, ensuring the installation and removal of the battery assembly.

[0048] See also Figure 4 , 5As shown, a barrier 11 is provided in the middle of the bottom surface of the placement groove 4, and the placement grooves 4 on both sides of the barrier 11 respectively form a positioning cavity 12, and a notch 13 matching the barrier 11 is provided in the middle of the bottom surface of the battery assembly 2, and the barrier 11 is inserted into the notch 13. Among them, the notch is set at the bottom of the lower battery box. The front end and the rear end of the barrier are respectively connected to the front inner wall and the rear inner wall of the placement groove, and there is a vertical spacing between the top of the barrier and the top of the placement groove.

[0049] The setting of the barrier separates the placement groove into a positioning cavity. The setting of the notch can also separate the battery compartment 10 into two sub-battery compartments. Batteries can be installed in each sub-battery compartment to separate the batteries, which can also facilitate heat dissipation when the batteries are working. At the same time, the lower battery box above the notch is not used for placing batteries, but can be used for arranging circuits to connect multiple batteries. At the same time, the upper battery box has a charging port 14 on it. The circuit is not only used to connect the battery, but also connected to the charging port. At the same time, a waterproof cover is set on the outside of the charging port for waterproofing.

[0050] Wherein, the first power connection position is arranged on the barrier member, and the second power connection position is arranged in the gap. Preferably, the barrier member has a cavity inside, and the cavity is connected to the top of the barrier member, and a detachable mounting cover plate on the top of the barrier member opens and closes the cavity. In this way, the first power connection position is installed on the cover plate, and the cavity of the barrier member can also be used for the arrangement of some lines, for connecting, placing, and storing the first power connection position and the motor and controller of the scooter. When performing subsequent maintenance, the battery assembly can be directly taken out from the placement slot, and then the cover plate can be opened to perform rapid line maintenance, etc.

[0051] Of course, the first power connection position may also be arranged in the positioning cavity, and thus the second power connection position is not arranged in the notch.
