[0008] In the above scheme, a corresponding vehicle-end connector is set in each mounting space to connect with the battery mounted in the corresponding mounting space, so that when the vehicle body mounts different numbers of batteries, the batteries can correspond one-to-one with the vehicle-end connector, reducing the difficulty of battery replacement and improving the efficiency of battery replacement.

[0009] According to some embodiments of the present application, the vehicle body includes a first vehicle-end connector and a second vehicle-end connector.

It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0057] The term "plurality" used in this application refers to two or more (including two).

[0058] In the embodiment of the present application, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0059] The battery cells can be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-hydrogen batteries, nickel-cadmium batteries, lead-acid batteries, etc., which are not limited in the embodiments of the present application.

[0060] A battery cell typically includes an electrode assembly. This assembly includes a positive electrode, a negative electrode, and a separator. During the charge and discharge process of a battery cell, active ions (such as lithium ions) are inserted and removed between the positive and negative electrodes. The separator, placed between the positive and negative electrodes, prevents short circuits between the positive and negative electrodes while allowing the active ions to pass through.

[0061] In some embodiments, the positive electrode may be a positive electrode sheet, which may include a positive electrode current collector and a positive electrode active material disposed on at least one surface of the positive electrode current collector.

[0062] In some embodiments, the negative electrode may be a negative electrode sheet, and the negative electrode sheet may include a negative electrode current collector.

[0063] In some embodiments, the electrode assembly further includes a separator disposed between the positive electrode and the negative electrode.

[0064] In some embodiments, the separator is a separator membrane. There are many types of separator membranes, and any known separator membrane with a porous structure having good chemical stability and mechanical stability can be selected.

[0065] In some embodiments, the battery cell further includes an electrolyte, which acts as a conductor of ions between the positive and negative electrodes. The electrolyte can be liquid, gel, or solid. Liquid electrolytes include an electrolyte salt and a solvent.

[0066] In some embodiments, the electrode assembly is a wound structure, wherein the positive electrode sheet and the negative electrode sheet are wound into the wound structure.

[0067] In some embodiments, the electrode assembly is a laminate structure.

[0068] As an example, multiple positive electrode sheets and multiple negative electrode sheets can be provided respectively, and the multiple positive electrode sheets and the multiple negative electrode sheets can be alternately stacked.

[0069] As an example, a plurality of positive electrode sheets may be provided, and the negative electrode sheet may be folded to form a plurality of stacked folded segments, with a positive electrode sheet being sandwiched between adjacent folded segments.

[0070] As an example, both the positive electrode sheet and the negative electrode sheet are folded to form a plurality of stacked folded segments.

[0071] As an example, a plurality of separators may be provided, each of which is disposed between any adjacent positive electrode sheets or negative electrode sheets.

[0072] As an example, the separator may be provided continuously, and may be provided between any adjacent positive electrode sheets or negative electrode sheets by folding or winding.

[0073] In some embodiments, the shape of the electrode assembly can be cylindrical, flat, or polygonal.

[0074] In some embodiments, the electrode assembly is provided with tabs that can conduct current from the electrode assembly. The tabs include a positive tab and a negative tab.

[0075] In some embodiments, a battery cell may include a housing. The housing is used to encapsulate components such as the electrode assembly and the electrolyte. The housing may be a steel housing, an aluminum housing, a plastic housing (e.g., polypropylene), a composite metal housing (e.g., a copper-aluminum composite housing), or an aluminum-plastic film.

[0076] As an example, the battery cells may be cylindrical, prismatic, soft-pack or other shaped battery cells. Prismatic battery cells include but are not limited to square-shell, blade-shaped, and polygonal batteries, such as hexagonal batteries.

[0077] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity.

[0078] In some embodiments, the battery may be a battery module. When there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0079] In some embodiments, the battery may be a battery pack, which includes a case and battery cells, wherein the battery cells or battery modules are housed in the case.

[0080] In some embodiments, the box body can be used as a part of the chassis structure of the vehicle. For example, part of the box body can become at least a part of the floor of the vehicle, or part of the box body can become at least a part of the cross beam and longitudinal beam of the vehicle.

[0081] New energy vehicles often use battery swapping to replenish power loss during driving. To reduce battery swapping costs, some vehicles currently feature removable frames with multiple batteries. The number of batteries mounted can be adjusted to meet varying driving range requirements, saving on swapping costs. However, changing the number of batteries can shift the vehicle's center of gravity, resulting in inconsistent front and rear battery weight distribution, impacting vehicle reliability.

[0082] In view of this, in order to improve the problem of the vehicle's center of gravity shifting due to the change in the number of mounted batteries, which affects the vehicle's driving reliability, some embodiments of the present application provide a vehicle body, which includes a frame. The frame is used to detachably connect to the battery, and the frame includes a first space, a second space, a third space, and a fourth space arranged along a first direction. The first space and the second space together form a first mounting space for accommodating the battery. The third space and the fourth space together form a second mounting space for accommodating the battery. The second space and the third space together form a third mounting space for accommodating the battery.

[0083] In the above scheme, by setting the first space, the second space, the third space and the fourth space arranged in sequence along the first direction x and the two adjacent spaces can jointly form the first mounting space, the second mounting space and the second mounting space, on the one hand, the vehicle body has the function of flexibly replacing batteries and adjusting the number of mounted batteries, which is beneficial to the control of vehicle driving costs; on the other hand, the third mounting space has an overlapping part with the first mounting space and the second mounting space, which can reduce the risk of the vehicle's center of gravity shifting due to changes in the number of mounted batteries, so that the front and rear weight distribution ratio of the vehicle is consistent, and the vehicle has higher driving reliability.

[0084] 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.

The 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. The vehicle 1000 includes a vehicle body 100 and a battery 300. The battery 300 may be disposed at the bottom, head, or tail of the vehicle body 100. The battery 300 may be used to power the vehicle 1000. For example, the battery 300 may serve as an operating power source for the vehicle 1000 and may be used for the circuit system of the vehicle 1000, such as for the working power requirements during startup, navigation, and operation of the vehicle 1000.

[0086] The vehicle body 100 may also include a frame 10, a controller 400, and a motor 500. The frame 10 may be connected to the battery 300. For example, the frame 10 may be detachably connected to the battery 300 to enable the vehicle 1000 to have a battery swapping function. The controller 400 and the motor 500 may be mounted on the frame 10. The controller 400 is used to control the battery 300 to supply power to the motor 500, for example, to meet the power requirements of the vehicle 1000 during startup, navigation, and driving.

[0087] In some embodiments of the present application, the battery 300 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.

[0088] See Figure 2-Figure 4 , Figure 2 This is a schematic diagram of a vehicle body 100 in some embodiments of the present application. Figure 3This is a schematic diagram of the vehicle body 100 when the first mounting space 110 and the second mounting space 111 are provided with batteries 300 in some embodiments of the present application. Figure 4 This is a schematic diagram of the vehicle body 100 when the third mounting space 112 is provided with a battery 300 in some embodiments of the present application.

For example, the vehicle frame 10 may include a longitudinal beam, and the mounting structure 114 may be a mounting hole provided on the longitudinal beam. For example, the vehicle frame 10 may include a battery swap bracket, and the mounting structure 114 may be a mounting hole provided on the battery swap bracket.

[0092] Optionally, the vehicle frame 10 includes two longitudinal beams arranged side by side, with an installation space for accommodating the battery 300 formed between the two longitudinal beams. Along the parallel direction of the two longitudinal beams, the opposite ends of the battery 300 can be detachably connected to the corresponding longitudinal beams. The mounting structure 114 can include a plurality of mounting holes provided on the longitudinal beams. On each longitudinal beam, the plurality of mounting holes are spaced apart along the length of the longitudinal beam, and the spacing between two adjacent mounting holes can be determined based on calculations, so that some mounting holes can mount batteries located in the first mounting space 110, some mounting holes can mount batteries located in the second mounting space 111, and some mounting holes can mount batteries located in the third mounting space 112.

[0093] The first direction x may be perpendicular to the direction of gravity. The first direction x may be parallel to the length direction of the vehicle body 100 or the width direction of the vehicle body 100. In some embodiments of the present application, the first direction x is parallel to the length direction of the vehicle body 100 for illustration.

[0094] See Figure 2, divided by dotted lines into a first space 11, a second space 12, a third space 13 and a fourth space 14 arranged along the first direction x. Among them, the above four spaces can provide three mounting positions for the battery 300, and the three mounting positions include a first mounting space 110 formed by the first space 11 and the second space 12, a second mounting space 111 formed by the third space 13 and the fourth space 14, and a third mounting space 112 formed by the second space 12 and the third space 13. Each mounting position can mount one or more batteries 300. Optionally, the number of batteries 300 that can be mounted on each mounting position is the same, or the specifications of the batteries 300 that can be mounted on each mounting position are consistent. Each mounting position is respectively provided with a mounting structure 114, and the mounting structure 114 in each mounting position can mount the corresponding battery 300. In some embodiments of the present application, it is taken as an example that each mounting position can mount a battery 300, that is, the first mounting space 110 can mount a battery 300, the second mounting space 111 can mount a battery 300, and the third mounting space 112 can mount a battery 300.

[0095] The three mounting positions provide two different postures for the vehicle 1000, including a first posture and a second posture. Figure 3 In the first posture, the first mounting space 110 and the second mounting space 111 of the vehicle frame 10 are respectively mounted with batteries 300, and the batteries 300 in the first mounting space 110 will occupy at least part of the first space 11 and at least part of the second space 12, and the batteries 300 in the second mounting space 111 will occupy at least part of the third space 13 and at least part of the fourth space 14. At this time, the center of gravity of the vehicle 1000 can be located between the second space 12 and the third space 13. Figure 4 In the second posture, the third mounting position of the frame 10 is mounted with a battery 300, and the battery 300 occupies at least part of the second space 12 and at least part of the third space 13. At this time, the center of gravity of the vehicle 1000 can be between the second space 12 and the third space 13. That is, it can be understood that changing the number of batteries 300 mounted on the vehicle has little effect on the center of gravity of the vehicle 1000.

[0096] In the above scheme, by setting the first space 11, the second space 12, the third space 13 and the fourth space 14 arranged in sequence along the first direction x and the two adjacent spaces can jointly form the first mounting space 110, the second mounting space 111 and the second mounting space 111, on the one hand, the vehicle body 100 has the function of flexibly replacing the battery 300 and adjusting the number of mounted batteries 300, which is beneficial to the control of the driving cost of the vehicle 1000; on the other hand, the third mounting space 112 has an overlapping part with the first mounting space 110 and the second mounting space 111, which can reduce the risk of the center of gravity of the vehicle 1000 shifting due to changes in the number of mounted batteries 300, so that the front and rear weight distribution ratio of the vehicle 1000 is consistent, and thus the vehicle 1000 has higher driving reliability.

[0097] According to some embodiments of this application, see Figure 5 , Figure 5 Schematic diagrams of a vehicle body 100 in other embodiments of the present application. Vehicle 1000 includes a first vehicle-end connector 20, a second vehicle-end connector 21, and a third vehicle-end connector 22. The first vehicle-end connector 20 is disposed in a first mounting space 110 and is configured to connect to a battery 300 located in the first mounting space 110. The second vehicle-end connector 21 is disposed in a second mounting space 111 and is configured to connect to a battery 300 located in the second mounting space 111. The third vehicle-end connector 22 is disposed in a third mounting space and is configured to connect to a battery 300 located in the third mounting space 112.

[0098] The vehicle-end connector is a component connected to the battery-end connector 31 of the battery 300. The vehicle-end connector may include, but is not limited to, a high- and low-voltage connector for connecting to the battery 300 or a liquid-cooling connector for connecting to the battery 300. In some embodiments, the high- and low-voltage connectors may be electrically connected to the battery 300 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 300 to perform thermal management of the battery 300. Optionally, each battery 300 needs to be connected to a corresponding vehicle-end connector to enable input or output of electrical energy, as well as input or output of electrical signals.

[0099] In some embodiments, the battery 300 includes a housing, battery cells, and a thermal management component. The housing is used to provide an assembly cavity for the battery cells and the thermal management component. The housing can have a variety of structures. Optionally, the housing can include a first housing body and a second housing body, with the first housing body and the second housing body overlapping each other, and the first housing body and the second housing body jointly defining an assembly cavity. Optionally, the first housing body and the second housing body can have a variety of structures. For example, the first housing body can be a hollow structure with one end open, and the second housing body can be a plate-like structure, with the second housing body overlapping the open side of the first housing body, so that the first housing body and the second housing body jointly define an assembly cavity. The first housing body and the second housing body can also be hollow structures with one end open, with the open side of the first housing body overlapping the open side of the second housing body. Of course, the housing formed by the first and second housing bodies can have a variety of shapes, such as a cylinder, a rectangular parallelepiped, or a cube. The thermal management component has a flow channel inside to accommodate a heat exchange medium, which is used for heat exchange with the battery cells to regulate the temperature of the battery cells. Optionally, the heat exchange medium may be a variety of substances. For example, the heat exchange medium may be a gas, such as air or hydrogen, or a liquid, such as water, a salt water solution or liquid nitrogen.

[0100] Optionally, the battery has a battery-end connector corresponding to the vehicle-end connector. The battery-end connector is generally provided on the housing, with the port for mating with the vehicle-end connector exposed. For example, the battery 300 may optionally be provided with a liquid cooling connector that mates with the liquid cooling connector. The two connectors may be plugged into each other via a socket plug to connect the vehicle-end water tank to the thermal management component, allowing the heat exchange medium to circulate between the vehicle and the battery 300.

[0101] The battery 300 can be provided with an electrical connector that matches the high and low voltage connectors. The electrical connector is mounted on the housing and electrically connected to the battery cells inside the housing. The electrical connector can be plugged into the high and low voltage connectors to enable the battery 300 to output or input electrical energy. For example, the high and low voltage connectors and the electrical connector each include a high-voltage terminal and a low-voltage terminal. When the high and low voltage connectors and the high-voltage terminals of the electrical connector are connected to each other, electrical energy can be transmitted. When the high and low voltage connectors and the low-voltage terminals of the electrical connector are connected to each other, signals, such as an interlock signal, can be transmitted.

[0102] In some embodiments, the vehicle-end connector and the battery-end connector 31 can be docked with each other in the form of sockets and plugs. For example, the vehicle-end connector is a plug and the battery-end connector 31 is a socket. When replacing the battery, the battery 300 can be mounted on the frame 10 from bottom to top and the battery-end connector 31 of the battery 300 is inserted into the vehicle-end connector.

[0103] The first vehicle-end connector 20, the second vehicle-end connector 21, and the third vehicle-end connector 22 are respectively disposed in the first mounting space 110, the second mounting space 111, and the third mounting space 112. When batteries 300 are mounted in the first mounting space 110 and the second mounting space 111, the batteries 300 in the first mounting space 110 can be connected to the first vehicle-end connector 20, and the batteries 300 in the second mounting space 111 can be connected to the second vehicle-end connector 21. When batteries 300 are mounted in the third mounting space 112, the batteries 300 in the third mounting space 112 can be connected to the third vehicle-end connector 22.

[0104] Exemplarily, the battery 300 includes a battery body 30 and a battery terminal connector 31. The battery terminal connector 31 is centrally located on the battery body 30. The first vehicle-end connector 20 is centrally located on the first mounting space 110. The second vehicle-end connector 21 is centrally located on the second mounting space 111. The third mounting space 112 is centrally located on the third mounting space 112. When the vehicle 1000 switches from the first posture to the second posture, or from the second posture to the first posture, the change in the number of batteries 300 has little or no effect on the location of the center of gravity of the vehicle 1000.

[0105] Based on an embodiment in which each mounting space is provided with a vehicle-end connector, a method for optionally adjusting the number of batteries 300 is provided, which includes the battery replacement device taking out the battery 300 from the first mounting space 110 or the second mounting space 111, and then removing the battery 300 from the second mounting space 111 or the first mounting space 110 and moving it horizontally to the third mounting space 112, and mounting the battery 300 in the third mounting space 112.

[0106] In the above solution, a corresponding vehicle-end connector is set in each mounting space to connect with the battery 300 mounted in the corresponding mounting space, so that when the vehicle body 100 mounts different numbers of batteries 300, the battery 300 can correspond one-to-one with the vehicle-end connector, thereby reducing the difficulty of battery replacement and improving the efficiency of battery replacement.

[0107] According to some embodiments of this application, see Figure 2 The vehicle body 100 includes a first vehicle-end connector 20 and a second vehicle-end connector 21. The first vehicle-end connector 20 is disposed in the second space 12 and is used to connect to the battery 300 located in the first mounting space 110 or the battery 300 located in the third mounting space 112. The second vehicle-end connector 21 is disposed in the second mounting space 111 and is used to connect to the battery 300 located in the second mounting space 111.

[0108] The vehicle-end connector is a component connected to the battery-end connector 31 of the battery 300. The vehicle-end connector may include, but is not limited to, a high- and low-voltage connector for connecting to the battery 300 or a liquid-cooling connector for connecting to the battery 300. In some embodiments, the high- and low-voltage connectors may be electrically connected to the battery 300 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 300 to perform thermal management of the battery 300. Optionally, each battery 300 needs to be connected to a corresponding vehicle-end connector to enable input or output of electrical energy, as well as input or output of electrical signals.

[0109] In some of these embodiments, the first vehicle-end connector 20 is a vehicle-end connector arranged in the second space 12 , which can be connected to the battery 300 mounted in the first mounting space 110 , and can also be connected to the battery 300 mounted in the third mounting space 112 .

[0110] Optionally, the battery end connector 31 is eccentrically arranged on the battery body 30, and the battery 300 is rotated relative to the position of the first vehicle end connector 20, so that the battery end connector 31 can be connected to the first vehicle end connector 20 when mounted in the first mounting space 110 or the third mounting space 112, without affecting the position of the center of gravity of the vehicle 1000.

[0111] Exemplarily, the first vehicle-end connector 20 is used for input and output of electric energy, and includes at least a positive high-voltage terminal and a negative high-voltage terminal. The corresponding battery-end connector 31 also includes a positive high-voltage terminal and a negative high-voltage terminal. If the positive and negative poles are to be correctly connected under the condition that the battery 300 changes its posture, the first vehicle-end connector 20 and / or the battery-end connector 31 need to be improved. Taking the improvement of the first vehicle-end connector 20 as an example, the first vehicle-end connector 20 includes a first polarity high-voltage terminal and two second polarity high-voltage terminals, and the first polarity and the second polarity are mutually opposite. When the battery 300 is mounted in the first mounting space 110, the first polarity high-voltage terminal of the battery-end connector 31 is connected to one of the second polarity high-voltage terminals of the first vehicle-end connector 20, and the second polarity high-voltage terminal of the battery-end connector 31 is connected to the first polarity high-voltage terminal of the first vehicle-end connector 20. The battery 300 can be mounted in the second mounting space 111 after being rotated by a certain angle relative to the first polarity high-voltage terminal of the first vehicle-end connector 20, for example, by being rotated 180 degrees. The first polarity high-voltage terminal of the battery-end connector 31 is connected to the other second polarity high-voltage terminal of the first vehicle-end connector 20, and the second polarity high-voltage terminal of the battery-end connector 31 is connected to the first polarity high-voltage terminal of the first vehicle-end connector 20, so that after the battery 300 is rotated, it can be connected to the positive and negative poles of the vehicle end, thereby realizing the output and input of electric energy. Taking the improvement of the battery-end connector 31 as an example, similar to the improvement of the first vehicle-end connector 20, the battery-end connector 31 includes a first polarity high-voltage terminal and two second polarity high-voltage terminals, so that after the battery 300 is rotated, it can be connected to the positive and negative poles of the vehicle end, thereby realizing the output and input of electric energy. Similarly, optionally, the battery-end connector 31 and the first vehicle-end connector 20 can be improved at the same time, with the battery-end connector 31 including a first polarity high-voltage terminal and two second polarity high-voltage terminals, and the first vehicle-end connector 20 including a second polarity high-voltage terminal and two first polarity high-voltage terminals, so that after the battery 300 rotates, it can be connected to the positive and negative poles of the vehicle end to realize the output and input of electrical energy.

[0112] The second vehicle-end connector 21 is used to connect to the battery 300 mounted in the second mounting space 111. In some embodiments, the second vehicle-end connector 21 can be disposed in the third space 13, the fourth space 14, or partially disposed in the third space 13 and partially disposed in the fourth space 14. For example, the second vehicle-end connector 21 can be disposed in the fourth space 14.

[0113] In some embodiments, the second vehicle-end connector 21 may be the same as or different from the first vehicle-end connector 20. For example, based on the above embodiment of the improvement of the first vehicle-end connector 20, the second vehicle-end connector 21 may also include one first polarity high-voltage terminal and two second polarity high-voltage terminals. Alternatively, based on the above embodiment of the improvement of the first vehicle-end connector 20, the second vehicle-end connector 21 may remain unchanged and remain similar to the current vehicle-end connector, including one first polarity high-voltage terminal and one second polarity high-voltage terminal.

[0114] In the above scheme, by setting the first vehicle-end connector 20 in the area where the first mounting space 110 and the third mounting space 112 overlap with each other, and setting the second vehicle-end connector 21 in the area that does not overlap with the first mounting space 110 and the third mounting space 112, the battery 300 mounted on the first mounting space 110 or the battery 300 mounted on the third mounting space 112 can be connected to the first vehicle-end connector 20, thereby saving the cost of the vehicle-end connector compared to the scheme of setting a vehicle-end connector for each mounting space, which is beneficial to the cost control of the vehicle 1000.

[0115] According to some embodiments of the present application, a center line of the first vehicle-end connector 20 along the first direction x is collinearly arranged with a center line of the second space 12 along the first direction x.

[0116] The center line of the first vehicle-end connector 20 along the first direction x can be understood as being parallel to the first direction x. Similarly, the center line of the second space 12 along the first direction x is also parallel to the first direction x.

[0117] In some embodiments, the first direction x can be parallel to the length direction of the vehicle body 100, and the second direction y can be parallel to the width direction of the vehicle body 100. In embodiments where the battery 300 is rotated 180° relative to the position of the first vehicle-end connector 20 so that the battery-end connector 31 can be connected to the first vehicle-end connector 20 when mounted in either the first mounting space 110 or the third mounting space 112, the position of the battery 300 along the second direction y can remain consistent regardless of whether the battery 300 is in the first mounting space 110 or the second mounting space 111, thereby not affecting the position of the center of gravity of the vehicle 1000 in the width direction of the vehicle body 100.

[0118] In other embodiments, the first direction x may be parallel to the width direction of the vehicle body 100, and the second direction y may be parallel to the length direction of the vehicle body 100. In embodiments where the battery 300 is rotated 180° relative to the position of the first vehicle-end connector 20 so as to enable connection between the battery-end connector 31 and the first vehicle-end connector 20 when mounted in either the first mounting space 110 or the third mounting space 112, the position of the battery 300 along the second direction y may remain consistent regardless of whether the battery 300 is in the first mounting space 110 or the second mounting space 111, thereby not affecting the position of the center of gravity of the vehicle 1000 in the length direction of the vehicle body 100.

[0119] In the above scheme, by arranging the center line of the first vehicle-end connector 20 along the first direction x and the center line of the second space 12 collinearly, the influence of the battery 300 on the position of the center of the vehicle 1000 perpendicular to the first direction x when the battery 300 is mounted in the first mounting space 110 or the third mounting space 112 can be reduced, thereby reducing the risk of the vehicle 1000 rolling over, and further contributing to the improvement of the driving reliability of the vehicle 1000.

[0120] According to some embodiments of the present application, the battery 300 includes a battery body 30 and a battery end connector 31, the battery end connector 31 is eccentrically arranged on the battery body 30, and the posture of the battery 300 when it is located in the first mounting space 110 is rotated 180° relative to the posture of the battery 300 when it is located in the third mounting space 112.

[0121] Optionally, the battery 300 may be rectangular. When mounted on the vehicle frame 10, the length of the battery 300 is perpendicular to the length of the vehicle body 100, that is, the length of the battery 300 is perpendicular to the first direction x. The centerline of the battery connector 31 parallel to the first direction x may be collinear with the centerline of the battery body 30 parallel to the first direction x, and a distance exists between the centerline of the battery connector 31 parallel to the second direction y and the centerline of the battery body 30 parallel to the second direction y. When the battery 300 is in the first mounting space 110, it can be adjusted to the position in the second mounting space 111 by rotating 180° relative to the battery connector 31 or the first vehicle-end connector 20.

[0122] In the above scheme, by eccentrically setting the battery end connector 31 on the battery body 30, the battery 300 can be mounted in the first mounting space 110 or the third mounting space 112 by rotating 180° without affecting the center of gravity distribution of the vehicle 1000, so that the front and rear weight distribution ratio of the vehicle 1000 is consistent, and the vehicle 1000 has higher driving reliability.

[0123] In other embodiments, the battery 300 includes a battery body 30 and a battery terminal connector 31. The battery terminal connector 31 is eccentrically disposed on the battery body 30. The battery 300 is positioned in the first mounting space 110 at a different angle relative to the battery 300 in the third mounting space 112. For example, the different angle may be 90°. In these embodiments, the battery 300 may be square. The centerline of the battery terminal connector 31 parallel to the first direction x may be collinear with the centerline of the battery body 30 parallel to the first direction x, and a distance exists between the centerline of the battery terminal connector 31 parallel to the second direction y and the centerline of the battery body 30 parallel to the second direction y. The battery 300 may be adjusted from its position in the first mounting space 110 to its position in the second mounting space 111 by rotating 90° about the battery terminal connector 31 or the first vehicle-end connector 20.

[0124] According to some embodiments of this application, see Figure 6 , Figure 6 This is a schematic diagram of the first vehicle-end connector 20 in some embodiments of the present application. The first vehicle-end connector 20 includes a first body 201, a first high-voltage terminal 202, a second high-voltage terminal 203, and a third high-voltage terminal 204 disposed on the first body 201. The second high-voltage terminal 203 and the third high-voltage terminal 204 have the same polarity, while the first high-voltage terminal 202 and the second high-voltage terminal 203 have opposite polarity. The first high-voltage terminal 202 and the second high-voltage terminal 203 are used to connect to the battery 300 located in the first mounting space 110. The first high-voltage terminal 202 and the third high-voltage terminal 204 are used to connect to the battery 300 located in the third mounting space 112.

[0125] The first vehicle-side connector 20 may be a socket or plug that mates with the battery-side connector 31. The first body 201 may be a housing for the first vehicle-side connector 20, and its materials include, but are not limited to, polyamide, polybutylene terephthalate, ABS plastic, polycarbonate, or other materials. The first body 201 may carry high-voltage terminals and / or low-voltage terminals that are electrically connected to the battery-side connector 31. The high-voltage terminals may be high-voltage sockets or plugs for power input and output, and the low-voltage terminals may be pins for signal transmission. Optionally, the first body 201 may be formed with positioning structures that mate with corresponding positioning structures on the battery-side connector 31 to position and guide the first vehicle-side connector 20 for mating with the battery-side connector 31. The positioning structures on the first body 201 include, but are not limited to, positioning pins, positioning holes, or other structures provided on the first body 201. For example, the first body 201 may have a first region for accommodating the high-voltage terminals and / or low-voltage terminals. Positioning structures may be provided to the sides of the first region to facilitate alignment with the battery-side connector 31. Optionally, the positioning structure may include positioning pins arranged on both sides of the first area.

[0126] The first high-voltage terminal 202 is used to connect to the corresponding high-voltage terminal of the battery-side connector 31. For example, when the first high-voltage terminal 202 is a positive high-voltage terminal, it can be connected to the negative high-voltage terminal of the battery-side connector 31. The second high-voltage terminal 203 has an opposite polarity to the first high-voltage terminal 202. For example, the second high-voltage terminal 203 is a negative high-voltage terminal, which can be connected to the positive high-voltage terminal of the battery-side connector 31. The third high-voltage terminal 204 has an opposite polarity to the first high-voltage terminal 202. The third high-voltage terminal 204 has the same polarity as the second high-voltage terminal 203. For example, the third high-voltage terminal 204 is a negative high-voltage terminal, which can be connected to the positive high-voltage terminal of the battery-side connector 31. The second high-voltage terminal 203 and the third high-voltage terminal 204 can be arranged in parallel.

[0127] Optionally, taking the polarity of the first high-voltage terminal 202 as the positive pole as an example, when the battery 300 is mounted on the first mounting space 110, the negative high-voltage terminal of the battery-end connector 31 is connected to the first high-voltage terminal 202, and the positive high-voltage terminal of the battery-end connector 31 is connected to the second high-voltage terminal 203; when the battery 300 is mounted on the third mounting space 112, the negative high-voltage terminal of the battery-end connector 31 is connected to the first high-voltage terminal 202, and the positive high-voltage terminal of the battery-end connector 31 is connected to the third high-voltage terminal 204.

[0128] Optionally, taking the polarity of the first high-voltage terminal 202 as the positive pole as an example, when the battery end connector 31 has a negative high-voltage terminal and two positive high-voltage terminals, and the two positive high-voltage terminals are arranged centrally symmetrically with respect to the negative high-voltage terminal, when the battery 300 is mounted on the first mounting space 110, the negative high-voltage terminal of the battery end connector 31 is connected to the first high-voltage terminal 202, and the two positive high-voltage terminals of the battery end connector 31 are respectively connected to the second high-voltage terminal 203 and the third high-voltage terminal 204; when the battery 300 is mounted on the third mounting space 112, the negative high-voltage terminal of the battery end connector 31 is connected to the first high-voltage terminal 202, and the two positive high-voltage terminals of the battery end connector 31 are connected to the third high-voltage terminal 204 and the second high-voltage terminal 203.

[0129] In the above scheme, by setting a first high-voltage terminal 202 and a second high-voltage terminal 203 and a third high-voltage terminal 204 with opposite polarity to the first high-voltage terminal 202, the battery 300 can be connected to the first vehicle-end connector 20 when mounted in the first mounting space 110 or when mounted in the third mounting space 112, so that the battery 300 supplies power to the vehicle body 100, so that the vehicle 1000 can operate normally.

[0130] According to some embodiments of this application, see Figure 6 The second high-voltage terminal 203 and the third high-voltage terminal 204 are symmetrically arranged about the center of the first high-voltage terminal 202 .

[0131] In some embodiments, the first high-voltage terminal 202 can be set at the center of the first body 201. When the battery 300 is rotated 180° to switch from being mounted in the first mounting space 110 to being mounted in the third mounting space 112, the battery end connector 31 can be connected to the first high-voltage terminal 202, and can be connected to the second high-voltage terminal 203 and / or the third high-voltage terminal 204.

[0132] In the above scheme, by setting the first low-voltage terminal 205 and the second low-voltage terminal 206 to be symmetrical about the center of the first high-voltage terminal 202, the battery 300 can be switched between the first mounting space 110 and the third mounting space 112 by rotating 180° relative to the first high-voltage terminal 202, so that the front and rear weight distribution ratio of the vehicle 1000 is consistent, which is beneficial to improving the driving reliability of the vehicle 1000.

[0133] In some other embodiments, the angle between the second high-voltage terminal 203 and the third high-voltage terminal 204 and the center of the first high-voltage terminal 202 can be 90 degrees. In these embodiments, the battery 300 can be square. When the battery 300 is rotated 90 degrees to switch from being mounted in the first mounting space 110 to being mounted in the third mounting space 112, the battery terminal connector 31 can be connected to the first high-voltage terminal 202, and can also be connected to the second high-voltage terminal 203 and / or the third high-voltage terminal 204.

[0134] According to some embodiments of the present application, the first vehicle-end connector 20 also includes a first low-voltage terminal 205 and a second low-voltage terminal 206, the first low-voltage terminal 205 is used to connect to the battery 300 located in the first mounting space 110, and the second low-voltage terminal 206 is used to connect to the battery 300 located in the third mounting space 112.

[0135] The low-voltage terminals of the vehicle-side connector can be connected to the low-voltage terminals of the battery-side connector 31 to enable low-voltage signal transmission between the vehicle and the battery 300. Low-voltage signals include, but are not limited to, battery 300 temperature signals and interlock signals. The first low-voltage terminal 205 and the second low-voltage terminal 206 can be pins provided on the first body 201.

[0136] Optionally, when the battery 300 is mounted in the first mounting space 110, the low-voltage terminal of the battery end connector 31 can be connected to the first low-voltage terminal 205; when the battery 300 is mounted in the third mounting space 112, the low-voltage terminal of the battery end connector 31 can be connected to the second low-voltage terminal 206.

[0137] Optionally, the battery end connector 31 has two low-voltage terminals. When the battery 300 is mounted in the first mounting space 110, the two low-voltage terminals of the battery end connector 31 can be connected to the first low-voltage terminal 205 and the second low-voltage terminal 206 respectively; when the battery 300 is mounted in the third mounting space 112, the two low-voltage terminals of the battery end connector 31 can be connected to the first low-voltage terminal 205 and the second low-voltage terminal 206 respectively.

[0138] In some embodiments, the first low-voltage terminal 205 and the second low-voltage terminal 206 may be arranged in parallel.

[0139] In the above scheme, by setting two low-voltage terminals, the battery 300 can transmit signals with the vehicle end when it is mounted in the first mounting space 110 or the third mounting space 112, thereby facilitating the vehicle end's control and management of the battery 300 and improving the driving reliability of the vehicle 1000.

[0140] According to some embodiments of this application, see Figure 6The first low-voltage terminal 205 and the second low-voltage terminal 206 are symmetrically arranged about the center of the first high-voltage terminal 202 .

[0141] In some embodiments, the first high-voltage terminal 202 can be set at the center of the first body 201. When the battery 300 is rotated 180° to switch from being mounted in the first mounting space 110 to being mounted in the third mounting space 112, the battery end connector 31 can be connected to the first low-voltage terminal 205 and / or to the second low-voltage terminal 206.

[0142] In the above scheme, by setting the first low-voltage terminal 205 and the second low-voltage terminal 206 to be symmetrical about the center of the first high-voltage terminal 202, the battery 300 can be switched between the first mounting space 110 and the third mounting space 112 by rotating 180° relative to the first high-voltage terminal 202, so that the front and rear weight distribution ratio of the vehicle 1000 is consistent, which is beneficial to improving the driving reliability of the vehicle 1000.

[0143] In some other embodiments, the angle between the first low-voltage terminal 205 and the second low-voltage terminal 206 and the center of the first high-voltage terminal 202 can be 90 degrees. In these embodiments, the battery 300 can be square. When the battery 300 is rotated 90 degrees to switch from being mounted in the first mounting space 110 to being mounted in the third mounting space 112, the battery terminal connector 31 can be connected to the first high-voltage terminal 202 and can be connected to the first low-voltage terminal 205 and / or the second low-voltage terminal 206.

[0144] According to some embodiments of this application, see Figure 7 , Figure 7 Schematic diagram of the structure of the vehicle body 100 in some embodiments of the present application. The second space 12 is provided with a first mounting structure 1140, which is used to mount the battery 300 in the first mounting space 110 and the battery 300 in the third mounting space 112.

[0145] The mounting structure 114 is used to mount the battery 300, so that the battery 300 can be mounted on the vehicle frame 10 or removed from the vehicle frame 10, thereby realizing battery replacement of the vehicle 1000. The mounting structure 114 includes but is not limited to mounting holes provided on the vehicle frame 10, mounting screws, and other structures that can achieve detachable connection with the battery 300.

[0146] The first mounting structure 1140 is a structural member disposed in the second space 12 and is configured to engage with the battery 300 when the battery 300 is in the second space 12 to achieve connection between the battery 300 and the vehicle frame 10. Optionally, the first mounting structure 1140 is a mounting hole disposed in the second space 12. When the battery 300 is in the first mounting space 110, the battery 300 can engage with the first mounting structure 1140. When the battery 300 is in the third mounting space 112, the battery 300 can engage with the first mounting structure 1140.

[0147] In the above scheme, by setting the first mounting structure 1140 in the area where the first mounting space 110 and the third mounting space 112 overlap with each other, the battery 300 can have a good connection relationship with the frame 10 when mounted in the first mounting space 110 or the third mounting space 112, reducing the risk of the battery 300 falling off the frame 10, which is beneficial to improving the driving reliability of the vehicle 1000.

[0148] According to some embodiments of the present application, the third space 13 is provided with a second mounting structure 1141 , and the second mounting structure 1141 is used to mount the battery 300 in the second mounting space 111 and to mount the battery 300 in the third mounting space 112 .

[0149] The second mounting structure 1141 is a structural member disposed in the third space 13 and is configured to engage with the battery 300 when the battery 300 is in the third space 13, thereby connecting the battery 300 to the vehicle frame 10. Optionally, the second mounting structure 1141 is a mounting hole disposed in the third space 13. When the battery 300 is in the second mounting space 111, the battery 300 can engage with the second mounting structure 1141. When the battery 300 is in the third mounting space 112, the battery 300 can engage with the second mounting structure 1141.

[0150] For example, see Figure 7 The mounting structure 114 includes mounting holes. Along one side in the second direction y, the first space 11 is provided with two mounting holes, the second space 12 is provided with two mounting holes, the third space 13 is provided with two mounting holes, and the fourth space 14 is provided with a mounting hole. When the battery 300 is mounted in the first mounting space 110, one side of the battery 300 in the second direction y can cooperate with the two mounting holes in the first space 11 and the two mounting holes in the second space 12. When the battery 300 is mounted in the second mounting space 111, one side of the battery 300 in the second direction y can cooperate with the two mounting holes in the third space 13 and the two mounting holes in the fourth space 14. When the battery 300 is mounted in the third mounting space 112, one side of the battery 300 in the second direction y can cooperate with the two mounting holes in the second space 12 and the two mounting holes in the third space 13.

[0151] By setting the first mounting structure 1140 in the overlapping area of ​​the second mounting space 111 and the third mounting space 112, the battery 300 can have a good connection relationship with the frame 10 when mounted in the second mounting space 111 or the third mounting space 112, thereby reducing the risk of the battery 300 falling off the frame 10, which is beneficial to improving the driving reliability of the vehicle 1000.

[0152] According to other embodiments of the present application, see Figure 8 , Figure 8 Schematic diagrams of a vehicle body 100 in other embodiments of the present application. The vehicle frame 10 further includes 2n independent spaces 113, where n is an integer greater than or equal to 1. Along a first direction x, n independent spaces 113 are located on the side of the first space 11 facing away from the second space 12, and the remaining n independent spaces 113 are located on the side of the fourth space 14 facing away from the third space 13. Each independent space 113 is configured to accommodate a battery 300.

[0153] The independent space 113 can be similar to the first mounting space 110, the second mounting space 111, or the third mounting space 112, and is a space for accommodating one or more batteries 300. Each independent space 113 can be provided with a mounting structure 114 to mount the battery 300. For example, in some embodiments of the present application, the independent space 113 is used to accommodate a battery 300.

[0154] The vehicle frame 10 includes at least two independent spaces 113, with an even number of independent spaces 113 arranged outside the first space 11 and outside the fourth space 14. If the number of batteries 300 needs to be adjusted, to minimize or eliminate the impact on the center of gravity of the vehicle 1000, the same number of batteries 300 can be arranged outside the first space 11 and outside the fourth space 14, symmetrically relative to the third mounting space 112.

[0155] In the above scheme, by arranging the same number of independent spaces 113 on both sides of the first mounting space 110 and the second mounting space 111, when the vehicle 1000 adjusts the number of mounted batteries 300, the front and rear configurations can be consistent, thereby reducing the risk of the center of gravity of the vehicle 1000 shifting due to changes in the number of batteries 300, thereby affecting the driving reliability of the vehicle 1000.

[0156] Some embodiments of the present application further provide a vehicle 1000 , which includes the vehicle body 100 and a battery 300 . The battery 300 is detachably connected to the vehicle frame 10 .

[0157] The vehicle 1000 has the vehicle body 100 provided above. On the one hand, the vehicle 1000 has a battery replacement function and the number of batteries to be replaced can be adjusted. On the other hand, through the vehicle body 100 provided above, the risk of the center of gravity of the vehicle 1000 shifting due to adjusting the number of batteries 300 mounted on the vehicle 1000 can be reduced, so that the front and rear weight distribution ratio of the vehicle 1000 is consistent, and thus the vehicle 1000 has higher driving reliability.

[0158] According to some embodiments of this application, see Figure 2 、 Figure 9 and Figure 10 , Figure 9 This is a schematic diagram of a battery 300 in some embodiments of the present application.

[0159] Vehicle 1000 includes a first vehicle-end connector 20, which is disposed in second compartment 12. A battery 300 includes a battery body 30 and a battery-end connector 31, which is eccentrically disposed in battery body 30. Battery-end connector 31 includes a second body 310, a fourth high-voltage terminal 311, a fifth high-voltage terminal 312, and a sixth high-voltage terminal 313 disposed in second body 310. The fifth high-voltage terminal 312 and the sixth high-voltage terminal 313 have the same polarity, while the fourth high-voltage terminal 311 and the fifth high-voltage terminal 312 have opposite polarity. When battery 300 is in first mounting compartment 110, fourth high-voltage terminal 311 and fifth high-voltage terminal 312 are connected to first vehicle-end connector 20. When battery 300 is in third mounting compartment 112, fourth high-voltage terminal 311 and sixth high-voltage terminal 313 are connected to first vehicle-end connector 20.

[0160] The battery body 30 may be the primary structure of the battery 300. For example, the battery body 30 may include a housing and a plurality of battery cells 300 disposed within the housing. In some embodiments, the housing of the battery body 30 may be provided with a relief groove 32. The relief groove 32 may extend through the housing along a first direction x, and the battery terminal connector 31 may be disposed within the relief groove 32. The relief groove 32 may be used to route cables between batteries or to avoid other structural components. In other embodiments, the relief groove 32 may also extend through the housing along a second direction y.

[0161] The first vehicle-end connector 20 may be a socket or plug that mates with the battery-end connector 31. The first vehicle-end connector 20 is provided with high-voltage terminals and / or low-voltage terminals for electrical connection to the battery-end connector 31. The high-voltage terminals may be high-voltage sockets or plugs for power input and output, and the low-voltage terminals may be pins for signal transmission.

[0162] The battery-end connector 31 may be a socket or a plug that is plugged into the first vehicle-end connector 20 , and in some embodiments, the battery-end connector 31 may also be connected to the vehicle-end connector disposed in the second mounting space 111 .

[0163] The second body 310 may serve as the housing for the battery-side connector 31. Its materials include, but are not limited to, polyamide, polybutylene terephthalate, ABS plastic, polycarbonate, or other materials. The second body 310 may house high-voltage and / or low-voltage terminals, which are electrically connected to the vehicle-side connector. The high-voltage terminals may be high-voltage sockets or plugs for power input and output, while the low-voltage terminals may be pins for signal transmission. Optionally, the second body 310 may include positioning structures that mate with corresponding positioning structures on the vehicle-side connector to position and guide the first vehicle-side connector 20 and the battery-side connector 31. For example, the positioning structures of the second body 310 may mate with those of the first body 201. The positioning structures of the second body 310 may include, but are not limited to, positioning pins, positioning holes, or other structures provided on the second body 310. For example, the second body 310 may have a second region for accommodating the high-voltage and / or low-voltage terminals. Positioning structures may be provided to the sides of the second region to facilitate alignment with the vehicle-side connector 31. Optionally, the positioning structure may include positioning pins or positioning grooves provided on both sides of the second area.

[0164] The fourth high-voltage terminal 311 is used to connect to the corresponding high-voltage terminal of the vehicle-end connector. For example, when the fourth high-voltage terminal 311 is a negative high-voltage terminal, it can be connected to the positive high-voltage terminal of the vehicle-end connector. The fifth high-voltage terminal 312 has an opposite polarity to the fourth high-voltage terminal 311. For example, the fifth high-voltage terminal 312 is a positive high-voltage terminal, which can be connected to the negative high-voltage terminal of the vehicle-end connector. The sixth high-voltage terminal 313 has an opposite polarity to the fourth high-voltage terminal 311. The sixth high-voltage terminal 313 has the same polarity as the fifth high-voltage terminal 312. For example, the sixth high-voltage terminal 313 is a positive high-voltage terminal, which can be connected to the negative high-voltage terminal of the vehicle-end connector. The fifth high-voltage terminal 312 and the sixth high-voltage terminal 313 can be arranged in parallel.

[0165] In some embodiments, the battery terminal connector 31 is eccentrically disposed with respect to the battery body 30, meaning that the center of the battery terminal connector 31 does not coincide with the center of the battery body 30. For example, the centerline of the battery terminal connector 31 parallel to the first direction x can be collinear with the centerline of the battery body 30 parallel to the first direction x, and the centerline of the battery terminal connector 31 parallel to the second direction y is spaced apart from the centerline of the battery body 30 parallel to the second direction y. The first direction x and the second direction y are perpendicular to each other.

[0166] Optionally, taking the polarity of the fourth high-voltage terminal 311 as a negative pole as an example, when the battery 300 is mounted on the first mounting space 110, the positive high-voltage terminal of the first vehicle-end connector 20 is connected to the fourth high-voltage terminal 311, and the negative high-voltage terminal of the first vehicle-end connector 20 is connected to the fifth high-voltage terminal 312; when the battery 300 is mounted on the third mounting space 112, the positive high-voltage terminal of the first vehicle-end connector 20 is connected to the fourth high-voltage terminal 311, and the negative high-voltage terminal of the first vehicle-end connector 20 is connected to the sixth high-voltage terminal 313.

[0167] In the above scheme, by setting the fourth high-voltage terminal 311 and the fifth high-voltage terminal 312 and the sixth high-voltage terminal 313 with opposite polarity to the fourth high-voltage terminal 311, the battery 300 can be connected to the battery-end connector 31 and the first vehicle-end connector 20 when mounted in the first mounting space 110 or the third mounting space 112, so that the battery 300 supplies power to the vehicle body 100, so that the vehicle 1000 can operate normally.

[0168] According to some embodiments of the present application, the fifth high-voltage terminal 312 and the sixth high-voltage terminal 313 are symmetrically arranged with respect to the center of the fourth high-voltage terminal 311 .

[0169] In some embodiments, the fourth high-voltage terminal 311 can be set at the center of the second body 310. When the battery 300 is rotated 180° to switch from being mounted in the first mounting space 110 to being mounted in the third mounting space 112, the first vehicle-end connector 20 can be connected to the fourth high-voltage terminal 311, and can be connected to the fifth high-voltage terminal 312 and / or the sixth high-voltage terminal 313.

[0170] In the above scheme, by setting the fifth high-voltage terminal 312 and the sixth high-voltage terminal 313 to be symmetrical about the center of the fourth high-voltage terminal 311, the battery 300 can be switched between the first mounting space 110 and the third mounting space 112 by rotating 180° relative to the fourth high-voltage terminal 311, so that the front and rear weight distribution ratio of the vehicle 1000 is consistent, which is beneficial to improving the driving reliability of the vehicle 1000.

[0171] In some other embodiments, the angle between the fifth high-voltage terminal 312 and the sixth high-voltage terminal 313 and the center of the fourth high-voltage terminal 311 may be 90 degrees. In these embodiments, the battery 300 may be square. When the battery 300 is rotated 90 degrees to switch from being mounted in the first mounting space 110 to being mounted in the third mounting space 112, the first vehicle-end connector 20 can be connected to the fourth high-voltage terminal 311 and can also be connected to the fifth high-voltage terminal 312 and / or the sixth high-voltage terminal 313.

[0172] According to some embodiments of the present application, the battery-end connector 31 further includes a third low-voltage terminal 314 and a fourth low-voltage terminal 315. When the battery 300 is located in the first mounting space 110, the third low-voltage terminal 314 is connected to the first vehicle-end connector 20. When the battery 300 is located in the third mounting space 112, the fourth low-voltage terminal 315 is connected to the first vehicle-end connector 20.

[0173] The low-voltage terminal of the battery-end connector 31 can be connected to the low-voltage terminal of the first vehicle-end connector 20 to enable low-voltage signal transmission between the vehicle-end and the battery 300. The low-voltage signals include, but are not limited to, battery 300 temperature signals, interlock signals, etc. In some embodiments, the low-voltage terminal of the battery-end connector 31 can be connected to the low-voltage terminal of the vehicle-end connector disposed in the second mounting space 111 to enable low-voltage signal transmission between the vehicle-end and the battery 300. The low-voltage signals include, but are not limited to, battery 300 temperature signals, interlock signals, etc.

[0174] The third low-voltage terminal 314 and the fourth low-voltage terminal 315 may be pins provided on the second body 310 .

[0175] Optionally, when the battery 300 is mounted in the first mounting space 110, the low-voltage terminal of the first vehicle-end connector 20 can be connected to the third low-voltage terminal 314; when the battery 300 is mounted in the third mounting space 112, the low-voltage terminal of the first vehicle-end connector 20 can be connected to the fourth low-voltage terminal 315.

[0177] In some embodiments, the first low-voltage terminal 205 and the second low-voltage terminal 206 may be arranged in parallel.

[0178] In the above scheme, by setting two low-voltage terminals, the battery 300 can be connected to the first vehicle-end connector 20 when mounted in the first mounting space 110 or the third mounting space 112, thereby realizing signal transmission between the battery 300 and the vehicle end, thereby facilitating the vehicle end's control and management of the battery 300 and improving the driving reliability of the vehicle 1000.

[0179] According to some embodiments of the present application, the third low-voltage terminal 314 and the fourth low-voltage terminal 315 are symmetrically arranged with respect to the center of the fourth high-voltage terminal 311 .

[0181] In the above scheme, by setting the third low-voltage terminal 314 and the fourth low-voltage terminal 315 to be symmetrical about the center of the fourth high-voltage terminal 311, the battery 300 can be switched between the first mounting space 110 and the third mounting space 112 by rotating 180° relative to the fourth high-voltage terminal 311, so that the front and rear weight distribution ratio of the vehicle 1000 is consistent, which is beneficial to improving the driving reliability of the vehicle 1000.

[0182] According to some embodiments of this application, see Figures 1-10 , a vehicle 1000 is also provided, and the vehicle 1000 includes a vehicle body 100 and a battery 300.

[0183] The vehicle body 100 includes a frame 10 to which one or more batteries 300 can be detachably connected. Figure 2-Figure 4 The vehicle frame 10 includes a first space 11, a second space 12, a third space 13, and a fourth space 14 arranged along the length of the vehicle 1000.

[0185] A vehicle-end connector is provided in each of the second and fourth spaces 12, 14. The vehicle-end connector is configured to connect to the battery-end connector 31 of the battery 300. The vehicle-end connector provided in the second space 12 is defined as the first vehicle-end connector 20, and the vehicle-end connector provided in the fourth space 14 is defined as the second vehicle-end connector. When the battery 300 is mounted in the second mounting space 111, the battery-end connector 31 of the battery 300 connects to the second vehicle-end connector 21. When the battery 300 is mounted in the first mounting space 110 or the third mounting space 112, the battery-end connector 31 of the battery 300 can connect to the first vehicle-end connector 20.

[0186] In some embodiments, the structures of the first vehicle-end connector 20 and the second vehicle-end connector 21 can be the same. For example, the first vehicle-end connector 20 and the second vehicle-end connector 21 are standard connectors, which can have a pair of positive and negative high-voltage terminals and a low-voltage terminal.

[0187] See Figure 9 and Figure 10 The battery 300 includes a battery body 30 and a battery terminal connector 31 eccentrically disposed on the battery body 30. Optionally, the battery 300 may be rectangular. When the battery 300 is mounted on the vehicle frame 10, the length of the battery 300 is perpendicular to the length of the vehicle body 100, that is, the length of the battery 300 is perpendicular to the first direction x. The centerline of the battery terminal connector 31 parallel to the first direction x may be collinear with the centerline of the battery body 30 parallel to the first direction x, and a distance exists between the centerline of the battery terminal connector 31 parallel to the second direction y and the centerline of the battery body 30 parallel to the second direction y. When the battery 300 is in the first mounting space 110, it can be adjusted to the position when it is in the second mounting space 111 by rotating 180° relative to the battery terminal connector 31 or the first vehicle-end connector 20.
