The bottom area of ​​one end of the battery box without a cover may be understood as the surface area of ​​the battery box without a cover. The layout area of ​​the seat system may be the area used to layout the seat system.

[0040] Specifically, Figure 4As shown, the battery liquid cooling plate 410 is installed at the lower end of the battery box 420. In order to ensure that the battery box 420 can be correctly connected to the battery liquid cooling plate 410, the area of ​​the battery liquid cooling plate 410 should be larger than the battery box 420. It should be noted that since multiple seat systems 430 may need to be arranged in the vehicle, the area occupied by the seat system 430 should be less than half of the bottom area of ​​one end of the battery box without a cover, so as to ensure that at least two seat systems are arranged inside the vehicle.

[0041] The technical solution of the disclosed embodiment connects a battery liquid cooling plate that is larger than the bottom area of ​​one end of the battery box without a cover and the battery box, and makes the layout area of ​​the seat system smaller than one half of the bottom area of ​​one end of the battery box without a cover, thereby ensuring a stable connection between the battery box and the battery liquid cooling plate, and multiple seat systems can be arranged inside the vehicle, meeting the user's demand for the vehicle's carrying capacity.

[0042] On the basis of the above technical solution, the device further comprises a battery module, and the battery module is arranged in a rectangular space formed by the battery liquid cooling plate and the battery box.

[0043] Specifically, the battery module can be arranged in the rectangular space formed by the battery liquid cooling plate and the battery case. For example, multiple battery modules can be arranged in sequence in the rectangular space formed by the battery liquid cooling plate and the battery case, and then combined to form an energy storage device that provides electrical energy for the vehicle. Alternatively, the entire battery structure can be placed on the battery liquid cooling plate, and the battery can be sealed by the battery case to form a battery assembly structure consisting of the top of the battery module, the battery case and the battery liquid cooling plate.

[0044] The technical solution of the disclosed embodiment improves the integration level of the battery assembly in the electric vehicle by disposing the battery module in the rectangular space formed by the battery liquid cooling plate and the battery box, and eliminates the need for additional corresponding supporting devices, thereby improving the space utilization of the vehicle.

[0045] On the basis of the above technical solution, it also includes: sealing the top of the battery module to form the top of the battery box.

[0046] Specifically, after placing the battery module in the rectangular space formed by the battery liquid cooling plate and the battery box, the top of the battery module can be sealed to form the bottom of the battery box. For example, the top of the battery module can be sealed by laying a partition on the top of the battery module. It should be noted that since the battery module is used to provide energy for electric vehicles, the battery module may be dangerous. Therefore, in order to avoid the battery module from harming passengers, the top of the battery module needs to be sealed so that passengers cannot directly contact the battery module.

[0047] The technical solution of the disclosed embodiment forms the top of the battery box by sealing the top of the battery module after the battery module is arranged, so that passengers cannot directly contact the battery module, thereby ensuring the safety of the passengers and achieving the technical effect of improving the safety performance of the vehicle.

[0048] On the basis of the above technical solution, the seat comprises two parts: a seat back and a seat cushion; wherein the seat back and the seat cushion are connected via a rotating shaft, and the rotating shaft is used to adjust the opening of the seat.

[0049] The seat back can be the back of a vehicle seat, and correspondingly, the seat cushion can be the cushion structure of a vehicle seat. The rotating shaft can be understood as an axis connecting the seat back and the seat cushion for bearing both bending moment and torque during rotation. It should be noted that the corresponding type of rotating shaft is selected according to the different types of seats, for example, it can be a rotating shaft without angle restriction, a rotating shaft with angle restriction, a multi-stage torque rotating shaft, a fixed-point rotating shaft, a resistance rotating shaft, a combined rotating shaft, a wall-mounted rotating shaft, a switch rotating shaft, etc.

[0050] Specifically, a rotating shaft can be set between the seat back and the seat cushion to connect them, so that the user can adjust the seat opening through the seat rotating shaft. For example, the user can adjust the seat opening by turning the adjustment switch and applying force to the seat back, so that the seat back rotates backward. It should be noted that the adjustment range of the seat opening is 70 degrees to 180 degrees. In other words, due to the limited space in the vehicle, the traditional seat opening cannot reach 180 degrees. The present invention can control the seat to slide on the seat slide rail first, and then adjust the seat opening, so that the seat opening can reach 180 degrees, so that the user can lie flat on the seat.

[0051] The technical solution of the disclosed embodiment connects the seat back and the seat cushion through a rotating shaft, and the seat opening adjustment range is 70 degrees to 180 degrees, so that the user can adjust the seat opening according to needs, and can also adjust the position of the seat through the seat slide rail, so that the adjustable opening of the seat reaches 180 degrees, meeting the user's adjustment needs.

[0052] Based on the above embodiments, a battery assembly integrated with a seat is also provided, which mainly solves industry problems in the prior art such as low battery integration, low vehicle space utilization, and difficulty in seat arrangement.

[0053] like Figure 5 As shown, the battery assembly integrated with the seat includes

[0055] Specifically, the number of seat slide rails 2 is ≥ 2, which are evenly arranged under a single seat; the seat slide rail 2 is fixed above the seat support beam. The seat 3 is arranged above the seat slide rail 2, but can slide along the direction of the slide rail at the bottom. The battery liquid cooling plate 1 is integrated with the battery box 4 to form a sealed space at the bottom; the seat support beam 5 is integrated with the box frame 4 to enhance the fixing strength of the seat bottom. The seat 3 can be opened 70°-180°, so that the seat on the top of the battery pack can be completely flat, and the top of the battery assembly is integrated with the body. The seat is connected to the seat support beam 5 fixed to the battery to achieve a high degree of integration of the battery, body, and seat, thereby improving space utilization.
