[0047] For new energy vehicles, the vehicle-side connector and the battery-side connector plug into each other to achieve interaction between the vehicle and the battery, allowing the battery to power the vehicle. However, in current vehicles, the vehicle-side connector is located on the underside of the vehicle frame and protrudes toward the battery. This causes the vehicle-side connector to occupy space under the frame. To ensure the vehicle has appropriate ground clearance and meet driving conditions, this affects the battery's energy capacity and the vehicle's range.

[0048] In view of this, to address the issue of a vehicle-end connector occupying space below the vehicle frame, impacting battery energy capacity, and resulting in a reduced vehicle range, some embodiments of the present application provide a vehicle body comprising a frame and a vehicle-end connector. The frame is configured to connect to the battery, and along the direction of gravity, the frame has a lower side facing the battery, the lower side having an opening. The vehicle-end connector is configured to connect to the battery, the vehicle-end connector being disposed in the opening, and along the direction of gravity, at least a portion of the vehicle-end connector is located on the side of the lower side facing away from the battery.

[0049] In the above scheme, by arranging the vehicle-end connector in the opening and arranging at least part of the vehicle-end connector on the side of the lower side facing away from the battery, the space occupied by the vehicle-end connector under the frame can be effectively reduced. On the one hand, the influence of the vehicle-end connector on the ground clearance of the vehicle can be reduced, thereby improving the driving performance of the vehicle; on the other hand, a larger space can be provided for the battery, so that more or larger batteries can be arranged, thereby increasing the vehicle's cruising range.

[0050] The vehicle body disclosed in the embodiments of the present application may be used, but is not limited to, in the vehicle body of a passenger vehicle, the vehicle body of a commercial freight vehicle, and the body of a vehicle of other nature. The vehicle body disclosed in the embodiments of the present application may be used, but is not limited to, in the vehicle body of a passenger vehicle, the vehicle body of a commercial freight vehicle, and the body of a vehicle of other nature.

[0051] Please refer to Figure 1 , Figure 1 Schematic diagram of the structure of a vehicle provided for some embodiments of the present application. Vehicle 1000 may be a new energy vehicle, which may be a pure electric vehicle, a hybrid vehicle with a swappable battery, or an extended-range vehicle with a swappable battery, etc. Vehicle 1000 includes a vehicle body 100 and a battery 200. Battery 200 may be arranged at the bottom, head, or tail of the vehicle body 100. Battery 200 may be used to power vehicle 1000. For example, battery 200 may be used as an operating power source for vehicle 1000, for the circuit system of vehicle 1000, such as for the working power requirements during startup, navigation, and operation of vehicle 1000.

[0052] The vehicle body 100 may also include a frame 10, a controller 300, and a motor 400. The frame 10 may be connected to the battery 200. For example, the frame 10 may be detachably connected to the battery 200 to enable the vehicle 1000 to have a battery replacement function. The controller 300 and the motor 400 may be mounted on the frame 10. The controller 300 is used to control the battery 200 to supply power to the motor 400, for example, to meet the power requirements of starting, navigating, and driving the vehicle 1000. In some embodiments, the front and rear seats of the vehicle 1000 may be located on the upper side of the frame 10.

[0053] In some embodiments of the present application, the battery 200 can serve not only as an operating power source for the vehicle 1000, but also as a driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0054] Some embodiments of the present application provide a vehicle body 100, see Figure 2 , Figure 2 Schematic diagram of the vehicle frame 10 and the vehicle-end connector 20 in some embodiments of the present application.

[0055] Vehicle body 100 includes a frame 10 and a vehicle-end connector 20. Frame 10 is used to connect to battery 200. Frame 10 has a lower side 11 facing battery 200, along the direction of gravity z. Lower side 11 has an opening 110. Vehicle-end connector 20 is used to connect to battery 200 and is disposed in opening 110. At least a portion of vehicle-end connector 20 is located on the side of lower side 11 facing away from battery 200, along the direction of gravity z.

[0056] The frame 10 may be a structure of the vehicle body 100 for carrying various devices, for example, the motor 400, controller 300, seats and other devices of the vehicle body 100 may be disposed on the frame 10. In some embodiments, the frame 10 may include a chassis of the vehicle 1000.

[0057] Along the direction of gravity z, the battery 200 is arranged below the frame 10. Along the direction of gravity z, the surface of the frame 10 facing the battery 200 is the lower side 11 of the frame 10. In some embodiments, the lower side 11 of the frame 10 is the surface of the frame 10 closest to the battery 200. In some embodiments, the battery 200 can be fixedly connected to the frame 10, and in some embodiments, the battery 200 can be detachably connected to the frame 10. Exemplarily, the frame 10 can be provided with a mounting structure, and the battery 200 can be connected to the frame 10 through the mounting structure and can achieve battery replacement. The mounting structure includes but is not limited to mounting holes, mounting screws and other structures that can achieve detachable connection with the battery 200 provided on the frame 10. For example, the frame 10 may include a longitudinal beam, and the mounting structure may be a mounting hole provided on the longitudinal beam. Exemplarily, the frame 10 includes a battery replacement bracket, and the mounting structure may be a mounting hole provided on the battery replacement bracket.

[0058] The vehicle-end connector 20 is a component connected to the battery-end connector 201 of the battery 200. The vehicle-end connector 20 may include, but is not limited to, a high- and low-voltage connector for connecting to the battery 200 or a liquid-cooling connector for connecting to the battery 200. In some embodiments, the high- and low-voltage connectors may be electrically connected to the battery 200 to enable input or output of electrical energy, as well as input or output of electrical signals. The liquid-cooling connector may be used for input or output of a heat exchange medium of the battery 200 to perform thermal management on the battery 200. Optionally, each battery 200 needs to be connected to a corresponding vehicle-end connector 20 to enable input or output of electrical energy, as well as input or output of electrical signals.

[0059] In some embodiments, the vehicle-end connector 20 and the battery-end connector 201 can be docked with each other in the form of sockets and plugs, for example, the vehicle-end connector 20 is a plug and the battery-end connector 201 is a socket.

[0060] "The vehicle-end connector 20 is disposed in the opening 110. Along the gravity direction z, at least part of the vehicle-end connector 20 is located on the side of the lower side surface 11 facing away from the battery 200". It can be understood that an opening 110 is formed in the lower side surface 11 of the vehicle frame 10, and a space capable of accommodating the vehicle-end connector 20 is formed above the lower side surface 11, thereby reducing the occupation of the space below the vehicle frame 10 by the vehicle-end connector 20.

[0061] Optionally, the entire vehicle-end connector 20 is located above the lower side surface 11. When assembling the battery 200, the battery-end connector 201 can be inserted upward into the opening 110 to be connected to the vehicle-end connector 20 in the opening 110.

[0062] Optionally, part of the vehicle-end connector 20 is located above the lower side surface 11, and the other part can be located below the lower side surface 11.

[0063] Exemplarily, the vehicle frame 10 includes a longitudinal beam, and the lower side surface 11 is the surface of the longitudinal beam facing the battery 200. An opening 110 is provided on the lower side surface 11 of the longitudinal beam, and at least part of the vehicle-end connector 20 is placed inside the longitudinal beam to reduce the occupation of the space below the longitudinal beam by the vehicle-end connector 20.

[0064] Exemplarily, the vehicle frame 10 includes the bottom plate of the vehicle 1000, and the lower side surface 11 is the surface of the bottom plate facing the battery 200. An opening 110 is provided on the lower side surface 11 of the bottom plate, and at least part of the vehicle-end connector 20 is placed above the bottom plate to reduce the occupation of the space below the bottom plate by the vehicle-end connector 20. Alternatively, by using processes such as stamping or die-casting, corresponding convex portions 15 and concave portions 16 are formed on the bottom plate. The concave portion 16 is formed on the lower side surface 11 and the concave portion 16 forms the opening 110, and at least part of the vehicle-end connector 20 is placed inside the concave portion 16 to reduce the occupation of the space below the bottom plate by the vehicle-end connector 20.

[0065] In the above solutions, by disposing the vehicle-end connector 20 in the opening 110 and disposing at least part of the vehicle-end connector 20 on the side of the lower side surface 11 facing away from the battery 200, the occupation of the space below the vehicle frame 10 by the vehicle-end connector 20 can be effectively reduced. On the one hand, the influence of the vehicle-end connector 20 on the ground clearance of the vehicle 1000 can be reduced, thereby improving the driving performance of the vehicle 1000; on the other hand, more space can be provided for the battery 200, so that more or larger batteries 200 can be provided, and further the cruising range of the vehicle 1000 can be improved.

[0066] According to some embodiments of the present application, along the gravity direction z, the entire vehicle-end connector 20 is located on the side of the lower side surface 11 facing away from the battery 200.

[0067] In some embodiments, “along the gravity direction z, the entire vehicle-end connector 20 is located on the side of the lower side 11 away from the battery 200” can be understood as, along the gravity direction z, the vehicle-end connector 20 has a lower surface facing the battery 200, and the lower surface is located above the lower side 11, or it can be understood as, along the gravity direction z, the vehicle-end connector 20 does not extend beyond the lower side 11.

[0068] In some embodiments, the size of the opening 110 may be larger than the size of the vehicle-end connector 20 , that is, there is a gap between the wall of the frame 10 surrounding the opening 110 and the peripheral wall of the vehicle-end connector 20 , and the gap may allow the battery-end connector 201 to enter.

[0069] In some embodiments, the vehicle-end connector 20 can be in the form of a socket, the peripheral wall of the vehicle-end connector 20 can be close to the wall portion of the frame 10 that surrounds the opening 110, and the battery-end connector 201 can be in the form of a plug and inserted into the socket of the vehicle-end connector 20.

[0070] In the above solution, by setting the entire vehicle-end connector 20 to be located on the side of the lower side 11 away from the battery 200, the space occupied by the vehicle-end connector 20 below the frame 10 can be further reduced. On the one hand, it can enable the vehicle 1000 to have a larger ground clearance, thereby improving the driving performance of the vehicle 1000; on the other hand, it can provide more space for the battery 200, so that more or larger batteries 200 can be set, thereby improving the cruising range of the vehicle 1000.

[0071] According to some embodiments of the present application, the frame 10 is configured to be detachably connected to the battery 200 .

[0072] In some embodiments, the frame 10 can be detachably connected to the battery 200, enabling the vehicle 1000 equipped with the frame 10 to have a battery swapping function, thereby replenishing energy consumption in a timely manner. Optionally, the frame 10 can be provided with a mounting structure, including but not limited to mounting holes, mounting screws, and other structures provided on the frame 10 that enable detachable connection with the battery 200.

[0073] In the above solution, by setting the frame 10 to be detachably connected to the battery 200, the vehicle 1000 can have a battery replacement function, so that the power loss of the vehicle 1000 during driving can be replenished in time.

[0074] According to some embodiments of this application, see Figure 2, the vehicle frame 10 is used to connect multiple batteries 200. The lower side 11 has a plurality of openings 110, the number of vehicle end connectors 20 is multiple, the vehicle end connectors 20 correspond to the openings 110 one by one, the vehicle end connectors 20 are arranged in the corresponding openings 110, the vehicle end connectors 20 correspond to the batteries 200 one by one, and the vehicle end connectors 20 are used to connect to the corresponding batteries.

[0075] In some embodiments, the vehicle frame 10 may be fixedly connected with a plurality of batteries 200.

[0076] In some embodiments, the vehicle frame 10 may be detachably connected to a plurality of batteries 200 respectively, so that the vehicle 1000 has the function of adjustable number of batteries 200, and the number of mounted batteries 200 can be selected according to actual needs, thereby controlling the power consumption cost of the vehicle 1000.

[0077] In some embodiments, taking the first direction x as the length direction of the vehicle frame 10 as an example, the vehicle frame 10 is provided with a plurality of openings 110 along the first direction x, a vehicle end connector 20 is arranged in each opening 110, the vehicle frame 10 is provided with a plurality of batteries 200 along the first direction x, and the battery end connector 201 of each battery 200 can be connected to the corresponding vehicle end connector 20.

[0078] In some embodiments, among the multiple batteries 200 of the vehicle 1000, the position of the battery end connector 201 of each battery 200 relative to the battery 200 body may be the same or different. In some scenarios, there are hollow areas, recesses 16 or areas capable of accommodating the vehicle end connectors 20 on the vehicle frame 10 itself. These areas can be reasonably utilized to arrange the vehicle end connectors 20. Based on the position where the vehicle end connectors 20 are located, the position of the battery end connector 201 of the battery 200 relative to the battery 200 body is then determined.

[0079] In the above solution, by setting a plurality of batteries 200, the driver can select the number of batteries 200 on the vehicle 1000 according to his own driving needs. On the one hand, the purpose of saving the use cost of the batteries 200 is achieved, which is beneficial to reducing the use cost of the vehicle 1000. On the other hand, the weight of the vehicle 1000 can be reduced, thereby facilitating the improvement of the cruising range of the vehicle 1000.

[0080] According to some embodiments of the present application, please refer to Figure 3 , Figure 3 is a schematic diagram of a partial structure of the vehicle 1000 in some embodiments of the present application. The multiple vehicle end connectors 20 include a first vehicle end connector 21. The vehicle frame 10 has a pedal mounting position 12, the pedal mounting position 12 is used to mount a braking pedal 120, and along the gravity direction z, the braking pedal 120 is above the first vehicle end connector 21.

[0081] The first vehicle-end connector 21 can be one of the multiple vehicle-end connectors 20.

[0082] In some embodiments, the vehicle frame 10 has a hollow area 17 on the outer side of the front engine compartment panel. On the side of this area facing the rear of the vehicle, the vehicle frame 10 has a pedal mounting position 12, and the pedal mounting position 12 corresponds to the brake pedal 120, providing support for the installation of the brake pedal 120. The brake pedal 120 is used for the driver to step on to achieve the braking of the vehicle. In the vehicle body 100, the space below the brake pedal 120 is generally in a vacant state, and there is a space below it that can accommodate the vehicle-end connector 20.
