Description

Bracket, frame, battery, electrical equipment and battery replacement method

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 8, 2023, with application number 202311684171.6 and invention name “Bracket, frame, battery, electrical equipment and battery replacement method”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application belongs to the field of vehicle technology, and more specifically, relates to a bracket, a frame, a battery, an electrical device, and a battery replacement method. Background Art

[0003] The statements here only provide background information related to this application and do not necessarily constitute prior art. Currently, there are two types of passenger battery-swap electric vehicles: one equipped with a large-capacity battery pack and the other equipped with multiple small-capacity battery packs. When swapping batteries, the former requires a complete replacement, and the compatibility between different models is poor; although the latter can more flexibly choose the number of battery packs, the installation point of the battery pack is a fixed position. When the vehicle is equipped with different numbers of battery packs, the center of gravity of the vehicle will be greatly offset, resulting in large changes in the posture of the vehicle.

[0004] Application Contents

[0005] The purpose of the embodiments of the present application is to provide a bracket, a frame, a battery, an electrical device and a battery replacement method to solve the problem in the related art that the battery pack installation position in the electric vehicle is fixed, and the center of gravity of the vehicle will be shifted when carrying different numbers of battery packs.

[0006] In a first aspect, an embodiment of the present application provides a bracket, comprising a frame, wherein the frame is a symmetrical structure, a symmetry plane of the frame is a first plane, the first plane is parallel to a thickness direction of the frame, and the first plane is located in the middle of the frame along the first direction;

[0007] The frame is provided with a plurality of support beams for detachably connecting to the sides of the battery, the plurality of support beams being arranged along a first direction, and an installation area for installing the battery is formed between two support beams for connecting opposite sides of the same battery, and the interior of the frame is divided into a plurality of installation areas, and the plurality of installation areas are symmetrically arranged about the first surface;

[0008] The frame supports multiple battery replacement interfaces, which are used to detachably connect the battery replacement connectors on the battery.

[0009] In the technical solution of the embodiment of the present application, a plurality of installation areas for installing batteries are divided in the frame, and these installation areas are arranged symmetrically with respect to the first surface, and the first surface is also the symmetrical surface of the frame. Therefore, when replacing the battery, the batteries installed in the frame can be arranged symmetrically with respect to the first surface, so as to reduce the risk of tilting caused by the shift of the center of gravity of the bracket during use; and on the premise of satisfying the symmetrical layout of the batteries with respect to the first surface, batteries can be selectively installed in some of the installation areas to achieve more flexible battery replacement; when used in vehicles, the risk of a large shift of the center of gravity can be reduced.

[0010] In some embodiments, the installation area includes a plurality of first installation areas sequentially arranged along the first direction, and the plurality of first installation areas are symmetrically arranged with respect to the first surface.

[0011] The first installation area is provided to facilitate the arrangement and layout of the installation area and also to facilitate the installation of the battery on the bracket.

[0012] In some embodiments, the installation area further includes at least one second installation area along the first direction, all the second installation areas inside the frame are symmetrically arranged about the first surface, and opposite sides of the second installation area extend into two adjacent first installation areas respectively.

[0013] A second installation area is set up, and the opposite sides of the second installation area are extended to the two adjacent first installation areas respectively. Therefore, under the premise of ensuring the symmetrical layout of the batteries about the first side, the selection of the number of battery installations is more adaptable and the battery replacement is more flexible.

[0014] In some embodiments, the number of second mounting areas is smaller than the number of first mounting areas, and areas corresponding to the plurality of first mounting areas overlap areas corresponding to the second mounting areas.

[0015] The corresponding overall areas of multiple first installation areas cover the second installation area, so that the number of second installation areas is set to be smaller than the number of first installation areas, which is convenient for the layout of the first installation area and the second installation area, and also convenient for installing the number of batteries according to needs, better selection of installation areas, and flexible replacement of batteries.

[0016] In some embodiments, the number of second mounting areas is one less than the number of first mounting areas.

[0017] If the number of the second installation area is set to one less than the first installation area, then the number of the first installation area and the number of the second installation area must be an odd number and an even number, and the first installation area and the second installation area are symmetrical about the first surface. This can provide more options for adapting to the number of batteries to be installed and is more flexible.

[0018] In some embodiments, the number of first mounting areas is an even number.

[0019] If the number of first installation areas is an even number, the number of second installation areas is an odd number, and the maximum number of batteries installed in the frame is the number of first installation areas, and it can adapt to installing batteries corresponding to the number of first installation areas from 1, achieving more flexible battery replacement.

[0020] In some embodiments, two adjacent mounting areas arranged side by side along the first direction share the same support beam. The number of mounting areas is N, N is an odd number, and the number of support beams is 2N-1.

[0021] Through the above structure, the installation area is set to an odd number, and the installation area in the middle is symmetrical about the first surface, while the installation areas on both sides are symmetrically arranged. This can adapt to the installation of 1 to N batteries in the frame, realize more flexible battery replacement, and reduce the number of support beams.

[0022] In some embodiments, the battery exchange interface corresponds one-to-one to the first installation area, and the battery exchange interface is supported on the frame by sliding along the first direction.

[0023] The battery replacement interface corresponds one-to-one to the first installation area, and the battery replacement interface is slidably supported on the frame along the first direction, so that the battery replacement interface is not only suitable for connecting to the battery installed in the first installation area, but also for connecting to the battery installed in the second installation area, and the number of battery replacement interfaces can be reduced.

[0024] In some embodiments, a slide rail is installed on the frame, the slide rail extends along the first direction, and each battery exchange interface is slidably installed on the slide rail.

[0025] Slide rails are set up to support the battery swap interface and facilitate the smooth movement of the battery swap interface.

[0026] In some embodiments, the slide rail is integrated with the frame edge into an integral structure.

[0027] Integrating the slide rails with the frame border can reduce the volume and weight of the bracket and improve the integration.

[0028] In some embodiments, the bracket also includes a driver that drives each power exchange interface to move along the first direction, and the driver is supported on the frame.

[0029] Set up a driver to move the battery swap interface when swapping batteries.

[0030] In some embodiments, among the multiple support beams in the frame: the support beam at the edge in the first direction is integrated with the frame on the corresponding side of the frame into an integrated structure.

[0031] Integrating the support beam at the edge with the frame border can improve the integration, effectively utilize the frame border to support the battery, and reduce the volume and weight of the bracket.

[0032] In some embodiments, the bracket also includes an electrical box, and each power exchange interface is connected to the electrical box.

[0033] An electrical box is set up to connect each battery exchange interface to the electrical box. Therefore, when in use, it is only necessary to connect the electrical box to the equipment using the bracket to connect it to each battery exchange interface on the bracket. It is convenient to connect and easy to use.

[0034] In some embodiments, the battery replacement interface includes an electrical interface for connecting to an electrical connector of a battery and a support base for supporting the electrical interface, and the support base is supported on the frame.

[0035] The electrical interface is supported by the support base to facilitate connection between the electrical interface and the electrical connector of the battery. When the electrical interface is not connected to the battery, it is also convenient to install a cover or other structure on the support base to cover the electrical interface to protect the electrical interface.

[0036] In some embodiments, the battery replacement interface includes a pipe interface for connecting a pipe joint of the battery and a mounting base for supporting the pipe interface, and the mounting base is supported on the frame.

[0037] The mounting base is used to support the pipe interface to facilitate connection between the pipe interface and the pipe joint of the battery so as to supply coolant to the battery. When the pipe interface is not connected to the battery, it is also convenient to install a cover or other structure on the mounting base to cover the pipe interface to protect the pipe interface.

[0038] In some embodiments, the mounting base and support base of the same battery replacement interface are integrated into an integrated structure.

[0039] Integrating the mounting base and the support base into one can improve the integration, reduce the occupied space, and facilitate the connection of the pipe interface and the electrical interface with the pipe connector and the electrical connector of the battery.

[0040] In some embodiments, the bracket also includes a protective structure for protecting the battery replacement interface, and the protective structure is supported on the mounting base.

[0041] Setting up a protective structure can protect the battery swap interface and reduce the risk of foreign objects entering the battery swap interface.

[0042] In a second aspect, an embodiment of the present application provides a vehicle frame comprising a bracket as described in any of the above embodiments.

[0043] The vehicle frame of the embodiment of the present application, by using the bracket of the above-mentioned solution, can more flexibly replace the number of batteries and the number of installed batteries to adapt to different vehicle models and different vehicle usage scenarios.

[0044] In some embodiments, the vehicle frame includes a frame body, and the bracket is mounted on the frame body; or the frame body includes the bracket.

[0045] By installing the bracket on the frame, the bracket and the frame can be manufactured separately and then assembled, thereby improving production efficiency.

[0046] The frame includes a bracket, and the bracket can be used as a part of the frame to reduce the weight and volume of the frame.

[0047] In some embodiments, the first direction is parallel to the longitudinal direction of the frame; or, the first direction is perpendicular to the longitudinal direction of the frame.

[0048] Orienting the bracket's first direction parallel to the longitudinal direction of the vehicle frame allows the batteries to be arranged transversely to the frame, minimizing the difference in load between the left and right sides of the frame due to changes in the number of batteries, thus reducing vehicle tilt. Positioning the batteries symmetrically about the first plane also helps balance the front-to-rear weight of the frame, reducing vehicle tilt.

[0049] Positioning the bracket's first direction perpendicular to the longitudinal direction of the vehicle frame allows the batteries to be arranged longitudinally along the frame. This prevents significant differences in front-to-back loads due to changes in the number of batteries, reducing vehicle tilt. Positioning the batteries symmetrically about the first plane further balances the left and right weights of the frame.

[0050] In a third aspect, an embodiment of the present application provides a battery for use with the bracket described in any of the above embodiments, and the battery is provided with a battery replacement connector for detachably connecting to a battery replacement interface.

[0051] The batteries of the embodiment of the present application can be installed on the bracket of the above embodiment to achieve flexible installation and replacement of the number of batteries.

[0052] In some embodiments, a groove is provided on the battery, and the groove is used for receiving a support beam in a corresponding installation area.

[0053] A groove is provided on the battery to allow at least a portion of the battery to extend into the bracket. When the battery capacity is constant, the overall volume of the battery after being installed in the bracket can be reduced.

[0054] In a fourth aspect, an embodiment of the present application provides an electrical device, comprising the bracket as described in any of the above embodiments, or the frame as described in any of the above embodiments, or the battery as described in any of the above embodiments.

[0055] The electrical equipment of the embodiment of the present application can realize flexible selection of the number of batteries for installation and replacement.

[0056] In a fifth aspect, an embodiment of the present application provides a battery replacement method for replacing a battery in the bracket described in any of the above embodiments. The battery replacement method includes the following steps:

[0057] Receive information about the number and location of batteries currently on the bracket, as well as the number of batteries to be replaced;

[0058] Make sure the number of batteries to be replaced is equal to the number of batteries on the bracket, and directly replace the batteries on the bracket;

[0059] Determine that the number of batteries to be replaced is not equal to the number of batteries on the bracket, remove the batteries on the bracket, and replace the same number of new batteries on the bracket according to the number of batteries to be replaced.

[0060] The battery replacement method of the embodiment of the present application can realize the installation of different numbers of batteries on the bracket, and make the overall bracket symmetrical about the first side after the batteries are installed, so that when in use, the weight of the bracket on both sides of the first side is balanced, which is convenient for use.

[0061] In some embodiments, the battery replacement interface on the bracket is slidably supported on the frame along a first direction;

[0062] After determining that the number of batteries to be replaced is not equal to the number of batteries on the bracket, remove the batteries on the bracket, push the battery replacement interface to the position corresponding to the installation area where the new batteries are to be installed, and then install the new batteries in the installation area.

[0063] By moving the battery replacement interface, the required number of new batteries can be installed on the bracket symmetrically with respect to the first side, so that the weight of the bracket with the new batteries installed on both sides of the first side can be better balanced, and the bracket can be better adapted to install different numbers of batteries.

[0064] In some embodiments, a driver is provided on the bracket to drive the battery replacement interface to move. When it is determined that the number of batteries to be replaced is not equal to the number of batteries on the bracket, after removing the batteries on the bracket, the driver pushes the battery replacement interface to move to the position corresponding to the installation area where the new battery is to be installed, and then the new battery is installed in the installation area.

[0065] Through the above steps, the driver is used to move the battery replacement interface, so that the battery replacement interface can be accurately moved to the set position for installing a new battery.

[0066] In some embodiments, the battery swap station is provided with a pusher for driving the battery swap interface to move. When it is determined that the number of batteries to be replaced is not equal to the number of batteries on the bracket, after removing the batteries on the bracket, the pusher pushes the battery swap interface to move to the position corresponding to the installation area where the new batteries are to be installed, and then the new batteries are installed in the installation area.

[0067] Through the above steps, a pusher is set at the battery swap station, and the battery swap interface is moved using the pusher, so that the battery swap interface can be accurately moved to the set position for installing a new battery. In addition, by setting a pusher at the battery swap station, there is no need to set a driver on the bracket, which can further reduce the weight and cost of the bracket.

[0068] In some embodiments, the support beam on the bracket is slidably installed on the frame. After determining that the number of batteries to be replaced is not equal to the number of batteries on the bracket, after removing the batteries on the bracket, the support beam is pushed to move to the corresponding positions on the opposite sides of the installation area where the new batteries are to be installed, and then the new batteries are installed in the installation area.

[0069] By moving the support beam to opposite sides of the installation area where a new battery is to be installed, the new battery can be supported when the new battery is installed.

[0099] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0100] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0101] In the description of the embodiments of this application, the technical terms "first," "second," etc., are used solely to distinguish between different objects and should not be understood to indicate or imply relative importance, or to implicitly specify the quantity, specific order, or primary-secondary relationship of the technical features indicated. Therefore, a feature designated "first" or "second" may explicitly or implicitly include one or more of such features.

[0102] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments in any suitable manner.

[0103] In the description of the embodiments of this application, the term "and / or" is simply a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0104] In the description of the embodiments of this application, the term "plurality" refers to two or more (including two). Similarly, "multiple groups" refers to two or more (including two groups), and "multiple sheets" refers to two or more (including two sheets). "Several" means one or more, unless otherwise specifically defined.

[0105] In the description of the embodiments of the present application, the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting the embodiments of the present application.

[0106] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components.

[0108] In the description of the embodiments of this application, unless otherwise specified or limited, the technical term "adjacent" refers to proximity in position. For example, if there are three components A1, A2, and B, and the distance between A1 and B is greater than the distance between A2 and B, then A2 is closer to B than A1, that is, A2 is adjacent to B, or B is adjacent to A2. For another example, when there are multiple components C, the multiple components C are C1, C2, ..., C N , when one of the C components, such as C2, is closer to the B component than other C components, then B is adjacent to C2, or it can be said that C2 is adjacent to B.

[0109] In the embodiments of the present application, the battery is a device for providing electrical energy, including but not limited to a lithium-ion secondary battery, a lithium-ion primary battery, a lithium-sulfur battery, a sodium-lithium-ion battery, a sodium-ion battery or a magnesium-ion battery.

[0110] The linear drive module mentioned in the embodiments of this application refers to a device, component, module, or mechanism capable of driving a structural member to move linearly. The linear drive module can be a linear module, a screw-nut mechanism, a rack-and-pinion mechanism, a pneumatic cylinder, a hydraulic cylinder, etc. The linear drive module mentioned in the embodiments of this application can be any of these, and can be configured and used as needed.

[0111] The linear modules mentioned in the embodiments of this application are also called linear modules, linear slides, etc. Currently, widely used linear modules can be divided into: synchronous belt type, ball screw type, and linear motor type. When the linear drive module mentioned in the embodiments of this application adopts a linear module, it can adopt any of the synchronous belt type linear module, ball screw type linear module, and linear motor type linear module, and can be configured and used according to needs.

[0112] A synchronous belt-type linear module primarily consists of a belt, linear guide, coupling, and motor. The working principle of a synchronous belt-type linear module is as follows: the belt is mounted on drive shafts on both sides of the linear module, one of which serves as the power input shaft and is connected to the motor. A slider, which connects to the workpiece, is fixed to the belt. Rotation of the drive shaft drives the belt, which in turn drives linear movement of the slider.

[0113] Ball screw type linear modules mainly include ball screws, linear guides, ball screw support seats, motors, etc.

[0114] A ball screw converts rotary motion into linear motion, or vice versa. A ball screw primarily consists of a screw and a nut. The screw is a rod-shaped component with an external thread. The nut is a component with an internal thread. The external threads of the screw mate with the internal threads of the nut to allow the nut to be mounted on the screw. Rotation of the screw moves the nut on the screw, converting rotary motion into linear motion. By connecting the workpiece to the nut, linear movement of the nut drives the workpiece. Some ball screws also include balls, which primarily reduce friction between the nut and the screw.

[0115] Linear guides, also known as slides, linear guides, and linear slides, are used in linear reciprocating motion situations. They can bear a certain torque and achieve high-precision linear motion under high load conditions.

[0116] A linear motor module, also known as a linear motor, is a transmission device that converts electrical energy directly into linear motion mechanical energy without the need for any intermediate conversion mechanism.

[0117] The screw-nut mechanism mainly consists of a screw, a nut, and a motor. The nut is mounted on the screw, which is connected to the motor. The motor drives the screw to rotate, pushing the nut on the screw to achieve linear movement. When the nut moves linearly, the workpiece is connected to the nut.

[0118] A rack-and-pinion mechanism primarily consists of a gear, a rack, and a motor. The gear meshes with the rack, which in turn is connected to the motor. The motor drives the gear to rotate, causing the gear to push the rack in a linear motion. Connecting a workpiece to the rack allows the rack to move linearly, driving the workpiece in the same direction.

[0119] A cylinder is a mechanical component that guides a piston in linear reciprocating motion within the cylinder. It primarily consists of a barrel, end caps, a piston, a piston rod, and seals. The end caps fit over the ends of the barrel, while the piston rod is connected to the piston. The piston slides within the barrel, extending through the end caps. The seals seal the piston rod and the end caps. High-pressure gas is injected into the barrel on one side of the piston, pushing the piston linearly within the barrel, which in turn pushes the piston rod along the barrel. Connecting a workpiece to the piston rod allows linear movement of the workpiece.

[0120] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and uses it to produce linear reciprocating (or oscillating) motion. A hydraulic cylinder generally consists of a cylinder barrel, a cylinder head, a piston, a piston rod, and a sealing device. The cylinder head covers the end of the cylinder barrel, and the piston rod is connected to the piston. The piston slides into the cylinder barrel and extends through the cylinder head. A seal seals the piston rod and the end cap. This system primarily works by filling the cylinder barrel with high-pressure liquid on one side of the piston, pushing the piston linearly within the barrel, which in turn pushes the piston rod linearly along the barrel. Connecting a workpiece to the piston rod allows linear movement of the workpiece.

[0121] Vehicles are commonly used as a means of transportation. They typically consist of a frame and a body, with the body mounted on the frame. The frame supports the vehicle's power units, such as the motor and engine, and also supports power devices such as batteries.

[0122] The frame generally includes longitudinal beams and cross beams. The longitudinal beams are arranged along the front and rear directions of the vehicle, and the cross beams are arranged along the left and right directions of the vehicle. The two ends of the cross beam are connected to the two longitudinal beams to form the main structure of the frame.

[0123] Currently, there are two main approaches to installing batteries in electric vehicles: one is to install a single battery on the vehicle frame, which is usually large in capacity and volume; the other is to equip the vehicle frame with multiple smaller batteries.

[0124] For the first solution, since there is only one large battery, a larger battery must be replaced when replacing the battery. This has poor flexibility and cannot be adapted to multiple vehicle models.

[0125] For the second solution, the size of a single battery is smaller, making the battery more compatible with different models of vehicles. However, the installation position of each battery on the frame of this structure is fixed, and the multiple batteries are installed on the frame in the horizontal or vertical direction, that is, the length direction of each battery is arranged along the horizontal or vertical direction of the frame. If the battery is installed on the frame in the horizontal direction, when the number of batteries is reduced, the load on the front and rear axles of the vehicle will be greatly different, resulting in a large tilt of the vehicle front and rear, and a large difference in the front and rear ground clearance, etc., affecting the normal driving of the vehicle. If the battery is installed on the frame in the longitudinal direction, when the number of batteries is reduced, the load on the left and right sides of the vehicle will be greatly different, resulting in a large tilt of the vehicle left and right, affecting the normal driving of the vehicle. Therefore, for this structure, the current vehicle still needs to carry all the batteries to move, and its flexibility is also poor.

[0126] Based on the above considerations, in order to solve the problem that the battery pack installation position in an electric vehicle is fixed, and the center of gravity of the vehicle will shift when carrying different numbers of battery packs, an embodiment of the present application provides a bracket, which divides the inside of the frame of the bracket into multiple installation areas, and the multiple installation areas are arranged symmetrically with respect to the first surface. When replacing the battery, the batteries installed in the frame can be arranged symmetrically with respect to the first surface to reduce the risk of tilting caused by the shift of the center of gravity of the bracket during use, especially when used in a vehicle, the risk of tilting of the vehicle can be reduced; and on the premise of satisfying the symmetrical layout of the batteries with respect to the first surface, batteries can be selectively installed in some of the installation areas without carrying the maximum number of batteries, which has good flexibility and can make the replacement and installation of the number of batteries more flexible.

[0127] The bracket disclosed in the embodiments of this application can be used in a vehicle frame or vehicle. Of course, the bracket disclosed in the embodiments of this application can also be used in other electrical equipment that requires batteries, such as ships, spacecraft, and the like. Spacecraft can include aircraft, rockets, space shuttles, and spacecraft, among others. Vehicles can include pure electric vehicles, gasoline-powered vehicles, electric-gasoline hybrid vehicles, and the like.

[0128] For the convenience of explanation, an electric device is provided in accordance with an embodiment of the present application, and the electric device is explained by taking a vehicle as an example.

[0129] Please refer to Figure 1, which is a structural schematic diagram of a vehicle 1000 provided in some embodiments of the present application. The vehicle 1000 can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 200 is provided inside the vehicle 1000, and the battery 200 can be provided at the bottom, head or tail of the vehicle 1000. The battery 200 can be used to power the vehicle 1000. For example, the battery 200 can serve as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 1002 and a motor 1003. The controller 1002 is used to control the battery 200 to power the motor 1003, for example, for starting, navigating and driving the vehicle 1000.

[0130] In some embodiments of the present application, vehicle 1000 includes a frame 1004 and wheels 1001. Wheels 1001 are mounted on frame 1004, supporting frame 1004 through wheels 1001. Battery 200 can be mounted on frame 1004, supporting battery 200 through frame 1004. Of course, controller 1002 can also be mounted on frame 1004, supporting controller 1002 through frame 1004. Motor 1003 can also be mounted on frame 1004, supporting motor 1003 through frame 1004.

[0131] 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.

[0132] As shown in Figures 2 to 4 , the frame 1004 has a longitudinal direction and a transverse direction. The longitudinal direction is along the front-to-back direction, and the transverse direction is along the left-to-right direction. The frame 1004 also has a height direction, which is perpendicular to the front-to-back and left-to-right directions. During use, the thickness direction of the frame 1004 coincides with the height direction. As shown in Figures 2 to 5 , the X-axis is in the longitudinal direction, the Y-axis is in the transverse direction, and the Z-axis is in the height direction, which also corresponds to the thickness direction of the frame. The longitudinal direction X is perpendicular to the transverse direction Y and to the height direction Z, which is also perpendicular to the height direction Z.

[0134] Referring to Figures 2 to 4 , according to some embodiments of the present application, a frame 1004 is provided, including a frame body 30, and a bracket 100 on which a battery 200 is mounted. The bracket 100 supports the battery 200. The battery 200 is detachably mounted on the bracket 100 for easy replacement.

[0135] In some embodiments, the frame 30 includes the bracket 100 , that is, the bracket 100 is a part of the frame 30 of the vehicle frame 1004 to reduce the weight and volume of the vehicle frame 1004 .

[0136] In some embodiments, the bracket 100 is installed on the frame 30. By installing the bracket 100 on the frame 30, the bracket 100 and the frame 30 can be manufactured separately and then assembled, thereby improving manufacturing efficiency.

[0137] In some embodiments, the frame 30 includes a crossbeam 32 and two longitudinal beams 31. The ends of the crossbeam 32 connect the two longitudinal beams 31 to form the main structure of the frame 30. The crossbeam 32 is used to form the frame 30 and is arranged along the horizontal direction Y. The longitudinal beam 31 is used to form the frame 30 and is arranged along the horizontal direction Y.

[0138] Please refer to Figures 5 to 8. According to some embodiments of the present application, the present application provides a bracket 100, including a frame 11. The frame 11 is a symmetrical structure. The symmetrical plane of the frame 11 is the first plane 101. The first plane 101 is parallel to the thickness direction Z of the frame 11, and the first plane 101 is located in the middle of the frame 11 along the first direction W; the frame 11 is provided with a plurality of support beams 12 for detachably connecting the sides of the battery 200. The plurality of support beams 12 are arranged along the first direction W, and an installation area 16 for installing the battery 200 is formed between two support beams 12 on opposite sides of the same battery 200. The interior of the frame 11 is divided into a plurality of installation areas 16, and the plurality of installation areas 16 are symmetrically arranged about the first plane 101. The opposite sides of each installation area 16 are provided with support beams 12 on opposite sides for detachably connecting the battery 200; the frame 11 supports a plurality of battery replacement interfaces 13, and the battery replacement interface 13 is used to detachably connect the battery replacement connector 21 on the battery 200.

[0139] The bracket 100 refers to a structure for detachably supporting the battery 200 for use in electrical equipment. When the bracket 100 is applied to the electrical equipment, the battery 200 can be conveniently installed on the bracket 100 and then installed in the electrical equipment.

[0140] The frame 11 is a frame structure formed by a frame 110 of beams, rods, etc. Since the frame 11 is a frame structure, the frame 110 forms a hollow space inside.

[0141] The first direction W can be the width direction of the frame 11 or the length direction of the frame 11. When the bracket 100 is installed on the vehicle frame 1004, the first direction W can be along the longitudinal direction X or the transverse direction Y of the vehicle frame 1004.

[0142] The first surface 101 is a plane passing through the middle of the frame 11 in a first direction W and parallel to the thickness direction Z of the frame 11. The first direction W can be the length direction of the frame 11 or the width direction of the frame 11.

[0143] The frame 11 is symmetrical about the first surface 101 , and thus the frame 11 is a symmetrical structure, and its symmetry plane is the first surface 101 . The first direction W is perpendicular to the first surface 101 .

[0144] The support beam 12 refers to a beam or rod structure used to support the battery 200. Both ends of the support beam 12 are connected to the frame 11, thereby supporting the support beam 12 through the frame 11. When connected to the battery 200, the support beam 12 is removably connected to the side of the battery 200 to facilitate removal and replacement of the battery 200. In some embodiments, the support beam 12 and the battery 200 can be removably connected in various ways. For example, a latch can be provided on the support beam 12 and a socket can be provided on the battery 200 to achieve removable connection between the support beam 12 and the battery 200. During removal, the latch can be pushed away from the battery 200 by a robot at the battery swap station. For another example, a latch can be provided on the battery 200 and a socket can be provided on the support beam 12 to achieve removable connection between the battery 200 and the support beam 12. Of course, in some other embodiments, the battery 200 and the support beam 12 can also be removably connected using methods such as snap-fitting. In addition, the support beam 12 and the battery 200 can also be detachably connected using a structure such as a hook.

[0145] A plurality of support beams 12 are provided on the frame 11 . These support beams 12 are used to be detachably connected to the sides of the battery 200 , so that when the battery 200 is installed, the battery 200 is supported by the support beams 12 .

[0146] Arranging the plurality of support beams 12 along the first direction W means that the length directions of the support beams 12 are perpendicular to the first direction W, and the support beams 12 are arranged at intervals along the first direction W on the frame 11 .

[0147] Since the support beam 12 is used to detachably connect the side of the battery 200, two support beams 12 are required to connect the opposite sides of the battery 200 to stably support the battery 200. In this way, an installation area 16 for installing the battery 200 is formed between the two support beams 12.

[0148] The mounting area 16 is a region within the interior of the frame 11 that is used to mount the battery 200. That is, when the battery 200 is mounted on the bracket 100, the battery 200 is positioned at a position corresponding to the mounting area 16. The interior of the frame 11 is divided into multiple mounting areas 16, meaning that multiple mounting areas 16 are defined within the interior of the frame 11.

[0149] The multiple installation areas 16 are symmetrically arranged about the first surface 101, which means that all the installation areas 16 divided by the internal space of the frame 11 are symmetrical about the first surface 101. For example, when the divided installation areas 16 are located on both sides of the first surface 101, the installation areas 16 on both sides of the first surface 101 are symmetrical about the first surface 101; when the divided installation areas 16 are located at the location of the first surface 101, that is, the first surface 101 is in the installation area 16, then the installation area 16 is symmetrical about the first surface 101. The installation area 16 is used to install the battery 200. Since the multiple installation areas 16 are symmetrical about the first surface 101, when installing the battery 200, the installation area 16 corresponding to the first surface 101 can be selected to install the battery 200, so that the weight of the frame 11 on both sides of the first surface 101 is balanced, reducing the risk of tilting caused by the center of gravity shifting during use of the bracket 100. Since there are multiple installation areas 16, batteries 200 can be selectively installed in some of the installation areas 16 on the premise that the batteries 200 are symmetrically arranged about the first surface 101. The selection of the number of batteries 200 to be installed is more flexible, and the number of batteries 200 to be replaced is also more flexible, that is, more flexible battery replacement is achieved.

[0150] Support beams 12 are provided on opposite sides of each mounting area 16. Since the battery 200 is mounted in the mounting area 16, support beams 12 are provided on opposite sides of the mounting area 16 to support the battery 200.

[0151] The opposite sides of the battery 200 refer to the opposite sides in the length direction of the battery 200, that is, the width of the battery 200 is defined between the side surfaces on the opposite sides of the battery 200. When the battery 200 is installed on the bracket 100, the first direction W is perpendicular to the length direction of the battery 200, and the first direction W is parallel to the width direction of the battery 200.

[0152] A battery replacement connector 21 is provided on the battery 200 . The battery replacement connector 21 refers to a connector structure provided on the battery 200 for connecting to an external device, thereby supplying electric energy to the outside or charging the battery 200 .

[0153] The battery replacement interface 13 refers to an interface structure that is compatible with the battery replacement connector 21. The battery replacement interface 13 is connected to the battery replacement connector 21 to connect the battery replacement interface 13 to the battery 200.

[0154] The frame 11 supports multiple battery swap interfaces 13, and each battery swap interface 13 is supported by the frame 11. Multiple battery swap interfaces 13 are provided so that when multiple batteries 200 are installed on the frame 11 at the same time, each battery swap interface 13 can be connected to the battery swap connector 21 of the corresponding battery 200.

[0155] In the technical solution of the embodiment of the present application, a plurality of installation areas 16 for installing batteries 200 are divided in the frame 11, and these installation areas 16 are symmetrically arranged about the first surface 101, and the first surface 101 is also the symmetrical surface of the frame 11. Therefore, when replacing the battery, the batteries 200 installed in the frame 11 can be arranged symmetrically about the first surface 101 to reduce the risk of tilting caused by the shift of the center of gravity of the bracket 100 during use; and on the premise of satisfying the symmetrical layout of the batteries 200 about the first surface 101, batteries 200 can be selectively installed in some of the installation areas 16 to achieve more flexible battery replacement; when used in the vehicle 1000, the risk of a large shift of the center of gravity can be reduced.

[0156] When the frame 1004 of the embodiment of the present application uses the above-mentioned bracket 100 structure, the number of batteries 200 and the number of installed batteries 200 can also be changed more flexibly to adapt to different vehicle models and different vehicle usage scenarios.

[0157] In some embodiments, the frame 11 includes two first frames 111 and two second frames 112. The two first frames 111 are parallel and spaced apart, and the two second frames 112 are parallel and spaced apart. The ends of the first frame 111 are respectively connected to the two second frames 112. The second frames 112 extend parallel to the first direction W, and the first frames 111 extend perpendicular to the first direction W. The frame 11 has a simple structure and is easy to manufacture.

[0158] 2 and 3 , in some embodiments, the first direction W is perpendicular to the longitudinal direction X of the frame 1004 .

[0159] The first direction W is perpendicular to the longitudinal direction X of the frame 1004 , and the first direction W is parallel to the transverse direction Y of the frame 1004 . Therefore, when the battery 200 is installed on the bracket 100 , the length direction of the battery 200 is parallel to the longitudinal direction X of the frame 1004 .

[0160] By arranging the first direction W of the bracket 100 perpendicular to the longitudinal direction X of the frame 1004, the batteries 200 can be arranged along the longitudinal direction X of the frame 1004. This prevents significant differences in the front-to-rear load of the frame 1004 due to changes in the number of batteries 200, thereby reducing the front-to-rear tilt of the vehicle. Furthermore, the symmetrical arrangement of the batteries 200 about the first surface 101 can better balance the left and right gravity of the frame 1004.

[0161] In some embodiments, the first direction W is parallel to the transverse direction Y of the frame 1004. When the bracket 100 is part of the frame body 30 of the frame 1004, the first side frame 111 of the frame 11 can be used as the crossbeam 32 of the frame body 30, and the second side frame 112 can be used as the longitudinal beam 31 of the frame body 30.

[0162] 13 and 14 , FIG13 is a top view of a frame 1004 according to some embodiments of the present application, wherein a certain number of batteries 200 are installed in the bracket 100. FIG14 is a schematic diagram of the bracket 100 in FIG13 with another number of batteries 200 installed.

[0163] In some embodiments, the first direction W is parallel to the longitudinal direction X of the frame 1004 .

[0164] The first direction W is parallel to the longitudinal direction X of the frame 1004 , and the first direction W is perpendicular to the transverse direction Y of the frame 1004 . Therefore, when the battery 200 is installed on the bracket 100 , the length direction of the battery 200 is parallel to the transverse direction Y of the frame 1004 .

[0165] By arranging the first direction W of the bracket 100 parallel to the longitudinal direction X of the frame 1004, the batteries 200 can be arranged along the transverse direction Y of the frame 1004. This prevents significant differences in the left and right loads of the frame 1004 due to changes in the number of batteries 200, thereby reducing left-right tilt of the vehicle. Furthermore, arranging the batteries 200 symmetrically about the first surface 101 can better balance the front-to-back gravity of the frame 1004, thereby reducing the front-to-back tilt of the vehicle.

[0166] In some embodiments, the first direction W is parallel to the longitudinal direction X of the frame 1004. When the bracket 100 is part of the frame body 30 of the frame 1004, the first side frame 111 of the frame 11 can be used as the longitudinal beam 31 of the frame body 30, and the second side frame 112 can be used as the transverse beam 32 of the frame body 30.

[0167] Referring to FIG. 5 to FIG. 8 , in some embodiments, the mounting area 16 includes a plurality of first mounting areas 161 sequentially arranged along the first direction W, and the plurality of first mounting areas 161 are symmetrically arranged about the first surface 101 .

[0168] The first installation area 161 refers to a portion of the installation area 16 that divides the inner space of the frame 11 . The plurality of first installation areas 161 are sequentially arranged along the first direction W.

[0169] The multiple first mounting areas 161 are symmetrically arranged about the first surface 101, meaning that all first mounting areas 161 demarcated within the interior space of the frame 11 are symmetrical about the first surface 101. For example, when the demarcated first mounting areas 161 are located on both sides of the first surface 101, the first mounting areas 161 on both sides of the first surface 101 are symmetrical about the first surface 101; when the demarcated first mounting areas 161 are located where the first surface 101 is located, that is, when the first surface 101 is within the first mounting areas 161, the first mounting areas 161 are symmetrical about the first surface 101. Because the multiple first mounting areas 161 are symmetrical about the first surface 101, when installing the battery 200, the first mounting area 161 corresponding to the first surface 101 can be selected to install the battery 200. This balances the weight of the frame 11 on both sides of the first surface 101, reducing the risk of tilting due to a shift in the center of gravity of the bracket 100 during use. Since there are multiple first installation areas 161, batteries 200 can be selectively installed in some of the first installation areas 161 under the premise that the batteries 200 are symmetrically arranged about the first surface 101. The selection of the number of batteries 200 to be installed is more flexible, and the number of batteries 200 to be replaced is also more flexible, that is, more flexible battery replacement is achieved.

[0170] The first installation area 161 is provided to facilitate the arrangement and layout of the installation area 16 and also to facilitate the installation of the battery 200 on the bracket 100 .

[0171] Please refer to Figures 5 to 8. In some embodiments, the installation area 16 also includes at least one second installation area 162 provided along the first direction W. All the second installation areas 162 inside the frame 11 are symmetrically arranged about the first surface 101, and the opposite sides of the second installation area 162 extend into the two adjacent first installation areas 161 respectively.

[0172] The second installation area 162 refers to a portion of the installation area 16 that divides the inner space of the frame 11 . The plurality of second installation areas 162 are sequentially arranged along the first direction W.

[0173] The multiple second mounting areas 162 are symmetrically arranged about the first surface 101, meaning that all second mounting areas 162 demarcated within the interior space of the frame 11 are symmetrical about the first surface 101. For example, when the demarcated second mounting areas 162 are located on both sides of the first surface 101, the second mounting areas 162 on both sides of the first surface 101 are symmetrical about the first surface 101; when the demarcated second mounting areas 162 are located where the first surface 101 is located, that is, when the first surface 101 is within the second mounting areas 162, the second mounting areas 162 are symmetrical about the first surface 101. Because the multiple second mounting areas 162 are symmetrical about the first surface 101, when installing the battery 200, the second mounting area 162 corresponding to the first surface 101 can be selected to install the battery 200. This balances the weight of the frame 11 on both sides of the first surface 101 and reduces the risk of tilting due to a shift in the center of gravity of the bracket 100 during use. Since there are multiple second installation areas 162, batteries 200 can be selectively installed in some of the second installation areas 162 on the premise that the batteries 200 are symmetrically arranged about the first surface 101. The selection of the number of batteries 200 to be installed is more flexible, and the number of batteries 200 to be replaced is also more flexible, that is, more flexible battery replacement is achieved.

[0174] In addition, by setting the first installation area 161 and the second installation area 162 at the same time, it is possible to more flexibly select some of the first installation areas 161 and the second installation area 162 to install the batteries 200, on the premise that the batteries 200 are symmetrically arranged about the first surface 101. The selection of the number of batteries 200 to be installed is more flexible, and the number of batteries 200 to be replaced is also more flexible, that is, more flexible battery replacement is achieved.

[0175] The opposite sides of the second mounting area 162 extend into the two adjacent first mounting areas 161, respectively. This means that the two sides of the second mounting area 162 partially overlap with the two adjacent first mounting areas 161. In this way, the area where all the first mounting areas 161 in the frame 11 are located covers the area where the second mounting areas 162 are located. When a battery 200 is installed in a second mounting area 162, the battery 200 will occupy the space of the first mounting area 161 that overlaps with the second mounting area 162, and the two first mounting areas 161 cannot be used to install batteries 200. Conversely, when a battery 200 is installed in a first mounting area 161, the second mounting area 162 that overlaps with the first mounting area 161 cannot be used to install batteries 200. In this way, when installing batteries 200, you can more flexibly choose between the first mounting area 161 and the second mounting area 162 to install the batteries 200 based on the number of batteries 200.

[0176] A second installation area 162 is set, and the opposite sides of the second installation area 162 are respectively extended to the two adjacent first installation areas 161. Therefore, under the premise of ensuring the symmetrical layout of the batteries 200 about the first surface 101, the selection of the number of batteries 200 to be installed is more adaptable and battery replacement is more flexible.

[0177] In some embodiments, the number of the second mounting areas 162 is smaller than the number of the first mounting areas 161 , and the areas corresponding to the plurality of first mounting areas 161 cover the areas corresponding to the second mounting areas 162 .

[0178] Since the number of second installation areas 162 is less than the number of first installation areas 161, and the two sides of the second installation areas 162 extend to the two adjacent first installation areas 161, the areas corresponding to multiple first installation areas 161 cover the areas corresponding to the second installation areas 162, that is, the areas where all the first installation areas 161 in the frame 11 are located cover the areas where the second installation areas 162 are located.

[0179] The corresponding overall areas of multiple first installation areas 161 cover the second installation area 162, so that the number of second installation areas 162 is set to be smaller than the number of first installation areas 161, which is convenient for the layout of the first installation area 161 and the second installation area 162, and also convenient for installing the number of batteries 200 as needed, better selecting the installation area 16, and facilitating flexible replacement of the battery 200.

[0180] In some embodiments, the number of second mounting areas 162 is one less than the number of first mounting areas 161 .

[0181] If the number of second installation areas 162 is set to be one less than that of first installation areas 161, then the number of first installation areas 161 and the number of second installation areas 162 must be an odd number and an even number respectively, and the first installation areas 161 and the second installation areas 162 are both symmetrical about the first surface 101, so that more options for the number of batteries 200 to be installed can be more flexible.

[0182] In some embodiments, the number of first mounting areas 161 is an even number.

[0183] The first installation area 161 is set to an even number, and the number of the second installation areas 162 is one less than the number of the first installation areas 161, then the number of the second installation areas 162 is an odd number, and the second installation area 162 in the middle is symmetrically arranged about the first surface 101.

[0184] If the number of first installation areas 161 is an even number, and the number of second installation areas 162 is an odd number, then the maximum number of batteries 200 installed in the frame 11 is the number of first installation areas 161, and it can adapt to installing a corresponding number of batteries 200 from 1 to the first installation areas 161, achieving more flexible battery replacement.

[0185] In some embodiments, two adjacent mounting areas 16 along the first direction W share the same support beam 12 . The number of mounting areas 16 is N, N is an odd number, and the number of support beams 12 is 2N−1.

[0186] Two installation areas 16 that are adjacent to each other along the first direction W mean that the two installation areas 16 do not overlap in the first direction W.

[0187] Two mounting areas 16 adjacent to each other along the first direction W share the same support beam 12, which means that only one support beam 12 is provided between the two mounting areas 16 adjacent to each other along the first direction W, and the support beam 12 can simultaneously connect the batteries 200 in the two mounting areas 16. For example, two adjacent first mounting areas 161 share the same support beam 12, and two adjacent second mounting areas 162 share the same support beam 12.

[0188] With the above structure, an odd number of mounting areas 16 are provided. The central mounting area 16 is symmetrical about the first surface 101, while the mounting areas 16 on either side are symmetrically arranged. This allows for the installation of 1 to N batteries 200 in the frame 11, enabling more flexible battery replacement and reducing the number of support beams 12. Furthermore, this structure allows for each mounting area 16 where a battery 200 is installed, with two corresponding support beams 12 supporting the battery 200, thereby providing stable support for the battery 200.

[0189] During use, it is generally necessary to maintain the stability of the battery 200. Therefore, the support beam 12 can be fixed to the frame 11 to ensure a stable connection between the frame 11 and the support beam 12. This provides greater structural strength and facilitates the frame 11 to stably support the support beam 12. Thus, when the support beam is connected to the battery 200, it stably supports the battery 200. The support beam 12 can be fixed to the frame 11 using fasteners such as bolts and pins. Of course, the support beam 12 can also be welded to the frame 11 to ensure a stable connection between the support beam 12 and the frame 11.

[0190] In some embodiments, while a locking member is provided to securely lock the support beam 12 to the frame 11, and the locking member can be used to unlock the support beam 12 from the frame 11, the support beam 12 can also be slidably mounted on the frame 11 to adjust the position of the support beam 12 on the frame 11. When adjusting the position of the support beam 12 on the frame 11, the support beams 12 connected to the same battery 200 are generally adjusted together to support opposite sides of the battery 200. This is equivalent to moving two support beams 12 from one mounting area 16 for mounting the battery 200 to another mounting area 16. This structure can reduce the number of support beams 12 provided.

[0191] In some embodiments, a plurality of sockets may be provided along the first direction W on the frame 110 of the frame 11, such as a plurality of sockets provided on the second frame 112, and a latch may be provided on the support beam 12. The latch may be inserted into the socket to lock the support beam 12 on the frame 11, so that the frame 11 supports the support beam 12. When the latch is inserted into different sockets on the frame 11, the position of the support beam 12 on the frame 11 may be adjusted.

[0192] In some embodiments, a plurality of insertion holes can be provided along the first direction W on the frame 110 of the frame 11, such as a plurality of insertion holes provided on the second frame 112, and a through hole can also be provided on the support beam 12. Locking members such as latches and bolts can be passed through the insertion holes and the through hole to lock the support beam 12 on the frame 11, so that the frame 11 supports the support beam 12. When the locking members pass through different insertion holes on the frame 11, the position of the support beam 12 on the frame 11 can be adjusted. Of course, a plurality of hooks can also be provided along the first direction W on the frame 110 of the frame 11, such as a plurality of hooks provided on the second frame 112, and a hook can be provided on the support beam 12. The hooks of the support beam 12 are connected to different hooks on the frame 110 to adjust the position of the support beam 12. After the position of the support beam 12 is adjusted, the connection between the support beam 12 and the frame 110 can be locked using a latch, bolt, or other structure to fix the support beam 12 to the frame 110.

[0193] In some embodiments, the support beam 12 can also be slidably installed on the frame 11, so that when installing the battery 200, the support beam 12 can be moved to the opposite sides of the corresponding installation area 16 to support the battery 200, thereby reducing the number of support beams 12.

[0194] In some embodiments, the battery exchange interface 13 corresponds one-to-one to the first installation area 161; the battery exchange interface 13 is supported on the frame 11 by sliding along the first direction W.

[0195] The battery exchange interface 13 corresponds one to one with the first installation area 161, so the number of first installation areas 161 is consistent with the number of battery exchange interfaces 13, and the number of battery exchange interfaces 13 limits the maximum number of batteries 200 that can be installed in the frame 11. When each first installation area 161 is installed with a battery 200, the maximum number of batteries 200 is installed in the frame 11.

[0196] Since the battery exchange interface 13 corresponds to the first installation area 161 one by one, and the position of the battery exchange connector 21 on the battery 200 is fixed, and the second installation area 162 is different from the position of the first installation area 161 along the first direction W, when the battery exchange interface 13 corresponds to the first installation area 161 to connect the battery 200, if the battery 200 needs to be installed in the second installation area 162, the battery exchange interface 13 needs to be moved to connect to the battery exchange connector 21 on the battery 200. The battery exchange interface 13 is slidably supported on the frame 11 along the first direction W to facilitate the movement of the battery exchange interface 13 along the first direction W, so that it is in the second installation area 162.

[0197] The battery replacement interface 13 corresponds one-to-one to the first installation area 161, and the battery replacement interface 13 is slidably supported on the frame 11 along the first direction W, so that the battery replacement interface 13 is not only suitable for connecting to the battery 200 installed in the first installation area 161, but also suitable for connecting to the battery 200 installed in the second installation area 162, and the number of battery replacement interfaces 13 can be reduced.

[0198] In some embodiments, a slide rail 15 is installed on the frame 11 , and the slide rail 15 extends along the first direction W. Each battery exchange interface 13 is slidably installed on the slide rail 15 .

[0199] The slide rail 15 refers to a long rod-shaped rail guide structure installed on the frame 11 to guide the movement of the battery swap interface 13. The extension of the slide rail 15 along the first direction W means that the length direction of the slide rail 15 is along the first direction W. Each battery swap interface 13 is slidably installed on the slide rail 15 so that each battery swap interface 13 can move along the slide rail 15 to adjust the position of the battery swap interface 13 on the frame 11.

[0200] A slide rail 15 is provided to support the battery swap interface 13 and facilitate smooth movement of the battery swap interface 13 .

[0201] 9 and 10 , in some embodiments, the slide rail 15 and the frame 110 of the frame 11 are integrated into an integral structure.

[0202] The slide rail 15 is integrated with the frame 110 of the frame 11 into an integral structure, which means that the slide rail 15 is integrated with the frame 110 of the frame 11, that is, the frame 110 of the frame 11 integrates the function of the slide rail 15, or the slide rail 15 is fixed to the corresponding frame 110 as a whole. For example, the function of the slide rail 15 is integrated into the first frame 111, and the battery swap interface 13 is slidably installed on the first frame 111, and the first frame 111 supports and guides the movement of the battery swap interface 13.

[0203] Integrating the slide rail 15 with the frame 110 of the frame 11 can reduce the volume and weight of the bracket 100 and improve the integration level.

[0204] Referring to FIG. 13 and FIG. 14 , in some embodiments, a slide rail 15 may be provided separately and mounted on the frame 11 .

[0205] Please refer to Figures 7, 8, 15 to 20. Figure 7 is a schematic diagram of the structure of the first installation area 161 divided by the bracket 100 in some embodiments of the present application. Figure 8 is a schematic diagram of the structure of the second installation area 162 divided by the bracket 100 in Figure 7. Figure 15 is a schematic diagram of the structure of the first installation area 161 divided by the bracket 100 in other embodiments of the present application. Figure 16 is a schematic diagram of the structure of the second installation area 162 divided by the bracket 100 in Figure 15. Figure 17 is a schematic diagram of the structure of the first installation area 161 divided by the bracket 100 in still other embodiments of the present application. Figure 18 is a schematic diagram of the structure of the second installation area 162 divided by the bracket 100 in Figure 17. Figure 19 is a schematic diagram of the structure of the first installation area 161 divided by the bracket 100 in still other embodiments of the present application. Figure 20 is a schematic diagram of the structure of the second installation area 162 divided by the bracket 100 in Figure 19.

[0206] Referring to FIG. 7 and FIG. 8 , in this embodiment, there are two first installation areas 161 and one second installation area 162 , which can be adapted to install one battery 200 or two batteries 200 .

[0207] 15 and 16 , in this embodiment, there are four first installation areas 161 and one second installation area 162 , which can accommodate one battery 200 , two batteries 200 , three batteries 200 , and four batteries 200 .

[0208] Referring to Figures 17 and 18, in this embodiment, there are three first mounting areas 161 and two second mounting areas 162, which can accommodate the installation of one battery 200, two batteries 200, and three batteries 200. It is understandable that in this embodiment, only the first mounting area 161 is divided in the frame 11, and it can also accommodate the installation of one battery 200, two batteries 200, and three batteries 200. However, by also dividing the second mounting area 162, the two second mounting areas 162 can be brought closer together. When two batteries 200 are installed, the center of gravity of the bracket 100 and the batteries 200 as a whole can be moved closer to the first surface 101, that is, closer to the center of the frame 11.

[0209] 19 and 20 , in this embodiment, there are four first installation areas 161 and three second installation areas 162 , which can accommodate one battery 200 , two batteries 200 , three batteries 200 , and four batteries 200 .

[0210] It can be understood that in some embodiments, the number of the first installation areas 161 can also be set to other numbers, and the number of the second installation areas 162 can also be set to other numbers.

[0211] Referring to Figures 9 and 10, in some embodiments, a slide groove 151 can be provided on the slide rail 15, and the slide groove 151 is provided along the length direction of the slide rail 15. A matching structure 135 is provided on the battery swap interface 13, and the matching structure 135 extends into the slide groove 151 to cooperate and guide the battery swap interface 13 to move along the slide groove 151. The slide groove 151 refers to a groove structure provided on the slide rail 15.

[0212] In some embodiments, a groove structure may also be provided on the battery replacement interface 13 to slide in conjunction with the slide rail 15 .

[0213] In some embodiments, the bracket 100 also includes a driver 17 that drives each battery exchange interface 13 to move along the first direction W, and the driver 17 is supported on the frame 11.

[0214] The driver 17 refers to a linear module that can drive the device to move linearly, for example, the driver 17 can be a linear motor, etc. The driver 17 is supported on the frame 11 so as to be supported by the frame 11 .

[0215] A driver 17 is provided to move the battery-changing interface 13 when the battery is changed.

[0216] In some embodiments, the driver 17 may be mounted on the frame 11 . In some embodiments, when a slide rail 15 is mounted on the frame 11 , the driver 17 may be mounted on the slide rail 15 .

[0217] In some embodiments, when a slide groove 151 is provided on the slide rail 15 , the driver 17 may also be a matching structure 135 provided on the battery exchange interface 13 to adapt to the slide groove 151 .

[0218] In some embodiments, among the multiple support beams 12 in the frame 11 , the support beams 12 at the edge along the first direction W are integrated with the frame 110 at the corresponding side of the frame 11 into an integrated structure.

[0219] Since support beams 12 are provided on both sides of the installation area 16, a plurality of support beams 12 are provided in the frame 11. At least two of the support beams 12 are located on opposite sides of the support beams 12. In other words, the two support beams 12 on opposite sides are located at the edges of the support beams 12, and the two support beams 12 are located at the edges of the support beams 12 along the first direction W.

[0220] The support beam 12 at the edge along the first direction W is integrated with the frame 110 on the corresponding side of the frame 11 into an integral structure, which means that the corresponding frame 110 of the frame 11 can integrate the function of the support beam 12, or the support beam 12 at the edge is directly fixed to the corresponding frame 110 as a whole. For example, the second frame 112 is integrated with the corresponding support beam 12.

[0221] Integrating the support beam 12 at the edge with the frame 110 of the frame 11 can improve the integration level, effectively utilize the frame 110 of the frame 11 to support the battery 200 , and reduce the volume and weight of the bracket 100 .

[0222] In some embodiments, the support beam 12 may be spaced apart from the border 110 of the frame 11 , so that the support beam 12 and the frame 11 may be manufactured separately, and then the support beam 12 may be installed on the frame 11 .

[0223] In some embodiments, the bracket 100 further includes an electrical box 14 , and each battery replacement interface 13 is connected to the electrical box 14 .

[0224] The electrical box 14 is a structure that integrates and distributes connectors connected to the plurality of batteries 200 .

[0225] An electrical box 14 is provided to connect each battery exchange interface 13 to the electrical box 14 , so that when in use, it is only necessary to connect the electrical box 14 to the device using the bracket 100 to connect it to each battery exchange interface 13 on the bracket 100 , which is convenient to connect and easy to use.

[0226] Please refer to Figures 11 and 12. The battery replacement interface 13 includes an electrical interface 131 for connecting to the electrical connector 211 of the battery 200 and a support base 132 for supporting the electrical interface 131. The support base 132 is supported on the frame 11.

[0227] The electrical connector 211 refers to a connector provided on the battery 200 for connecting to an external device so that the battery 200 can supply power to the outside or charge the battery 200 .

[0228] The electrical interface 131 is an interface for connecting to the electrical connector 211 on the battery 200 .

[0229] The support base 132 refers to a base structure used to support the electrical interface 131 .

[0230] The electrical interface 131 is supported by the support base 132 to facilitate the connection between the electrical interface 131 and the electrical connector 211 of the battery 200. When the electrical interface 131 is not connected to the battery 200, it is also convenient to install a cover or other structure on the support base 132 to cover the electrical interface 131 to protect the electrical interface 131.

[0231] Since the battery 200 generates a large amount of heat during charging and discharging, a cooling pipeline is provided in some batteries 200 , and a pipe joint 212 is provided on the battery 200 to allow coolant to flow through the cooling pipeline inside the battery 200 to dissipate heat from the battery 200 .

[0232] In some embodiments, the battery replacement interface 13 includes a pipe interface 133 for connecting the pipe joint 212 of the battery 200 and a mounting base 134 supporting the pipe interface 133, and the mounting base 134 is supported on the frame 11.

[0233] The pipe interface 133 is an interface for connecting with the pipe joint 212 on the battery 200. The pipe interface 133 is connected to the pipe joint 212 to allow the coolant of the battery 200 to flow through the battery 200, thereby dissipating heat from the battery 200.

[0234] The mounting seat 134 is a seat structure used to support the pipe interface 133 .

[0235] The pipe interface 133 is supported by the mounting base 134 to facilitate connection of the pipe interface 133 to the pipe joint 212 of the battery 200 so as to supply coolant to the battery 200. When the pipe interface 133 is not connected to the battery 200, it is also convenient to install a cover or other structure on the mounting base 134 to cover the pipe interface 133 to protect the pipe interface 133.

[0236] In some embodiments, the mounting base 134 and the support base 132 of the same battery replacement interface 13 are integrated into an integrated structure.

[0237] Since the battery exchange interface 13 is connected to the electrical interface 131 of the battery 200 , the mounting seat 134 and the support seat 132 of the same battery exchange interface 13 refer to the mounting seat 134 and the support seat 132 corresponding to the electrical interface 131 and the pipe joint 212 connected to the same battery 200 .

[0238] The mounting base 134 and the support base 132 of the same power exchange interface 13 are integrated into an integrated structure, which means that the mounting base 134 and the support base 132 can be fixed as one, or a base body structure can be used, and the electrical interface 131 and the pipe joint 212 are both arranged on the base body structure, so that it has the function of both the support base 132 and the mounting base 134, so as to support the electrical interface 131 and the pipe joint 212 at the same time, which is not only convenient for installation and use. In addition, in some embodiments, when the power exchange interface 13 is slidably mounted on the frame 11, it is also convenient to move the power exchange interface 13. Of course, in some embodiments, when the mounting base 134 and the support base 132 are separated, and the power exchange interface 13 is slidably mounted on the frame 11, the mounting base 134 and the support base 132 can be slidably mounted on the frame 11 respectively.

[0239] Integrating the mounting base 134 and the support base 132 into one body can improve the integration, reduce the occupied space, and also facilitate the connection of the pipe interface 133 and the electrical interface 131 with the pipe connector 212 and the electrical connector 211 of the battery 200.

[0240] In some embodiments, the bracket 100 also includes a protective structure (not shown) for protecting the battery replacement interface 13 , and the protective structure is supported on the mounting seat 134 .

[0241] The protective structure refers to a structure that can protect the battery swap interface 13 to reduce the entry of foreign matter into the battery swap interface 13. The protective structure can be a cover covering the battery swap interface 13, or a structure such as a plate covering the battery swap interface 13.

[0242] The protective structure is supported on the mounting base 134 so as to support the protective structure through the mounting base 134. If the protective structure is a cover, the cover can be removably mounted on the mounting base 134 so that after the cover is removed, the battery swap interface 13 can be electrically connected. If the protective structure is a plate, the plate or film layer can be removably mounted on the mounting base 134 so that after the plate or film layer is removed, the battery swap interface 13 can be electrically connected.

[0243] Setting up a protective structure can protect the battery exchange interface 13 and reduce the risk of foreign objects entering the battery exchange interface 13.

[0244] In some embodiments, when the mounting base 134 and the supporting base 132 are separated, protective structures may be provided on the mounting base 134 and the supporting base 132 , respectively.

[0245] In some embodiments, when the opposing sides of the second mounting area 162 extend to two adjacent first mounting areas 161, the support beams 12 of the second mounting area 162 will be located in the two first mounting areas 161, while the support beams 12 of the first mounting area 161 will also be located in the second mounting area 162. This allows for a groove 22 to be provided on the battery 200 to avoid the support beams 12. That is, when the battery 200 is installed in the second mounting area 162, the support beams 12 in the second mounting area 162 will be placed in the groove 22. This allows the battery 200 to be inserted into the frame 11, reducing the overall thickness and occupying less space.

[0246] According to some embodiments of the present application, the present application provides a bracket 100, including a frame 11, which is symmetrically arranged about a first surface 101, the first surface 101 is parallel to the thickness direction Z of the frame 11, and the first surface 101 is located in the middle of the frame 11 along the first direction W; the interior of the frame 11 is divided into multiple installation areas 16, each installation area 16 is used to install a battery 200, and the multiple installation areas 16 are symmetrically arranged about the first surface 101. Support beams 12 for detachably connecting opposite sides of the battery 200 are provided on opposite sides of each installation area 16, and the support beams 12 are connected to the frame 11; the frame 11 supports multiple battery replacement interfaces 13, and the battery replacement interfaces 13 are used to detachably connect to the battery replacement connector 21 on the battery 200. The installation area 16 includes multiple first installation areas 161 arranged in sequence along the first direction W, and the multiple first installation areas 161 are symmetrically arranged about the first surface 101. The installation area 16 also includes at least one second installation area 162 provided along the first direction W. All the second installation areas 162 inside the frame 11 are symmetrically arranged about the first surface 101, and the opposite sides of the second installation areas 162 extend to the two adjacent first installation areas 161 respectively. The number of second installation areas 162 is one less than the number of first installation areas 161. The number of first installation areas 161 is an even number. Two installation areas 16 adjacent to each other side by side along the first direction W share the same support beam 12. The number of installation areas 16 is N, N is an odd number, and the number of support beams 12 is 2N-1. The battery exchange interface 13 corresponds one to one with the first installation area 161; the battery exchange interface 13 is supported on the frame 11 by sliding along the first direction W. The bracket 100 can be used to install 1 to N batteries 200. That is, any number of batteries 200 from 1 to N can be installed on the bracket 100, and the weight of the bracket 100 on both sides of the first surface 101 will not have a large difference, thereby reducing the risk of tilting due to uneven weight after different numbers of batteries 200 are installed on the bracket 100.

[0247] Please refer to FIG. 2 to FIG. 14 . According to some embodiments of the present application, the present application provides a vehicle frame 1004 including the bracket 100 as described in any of the above embodiments.

[0248] The vehicle frame 1004 of the embodiment of the present application, by using the bracket 100 of the above-mentioned solution, can more flexibly replace the number of batteries 200 and the number of installed batteries 200 to adapt to different vehicle models and different vehicle usage scenarios.

[0249] In some embodiments, the frame 30 includes the bracket 100, that is, the bracket 100 is a part of the frame 30 of the vehicle frame 1004. The frame 30 includes the bracket 100, and the bracket 100 can be used as a part of the frame 30 to reduce the weight and volume of the vehicle frame 1004.

[0250] In some embodiments, the bracket 100 is installed on the frame 30. By installing the bracket 100 on the frame 30, the bracket 100 and the frame 30 can be manufactured separately and then assembled, thereby improving manufacturing efficiency.

[0251] 2 and 3 , in some embodiments, the first direction W is perpendicular to the longitudinal direction X of the frame 1004 .

[0252] The first direction W is perpendicular to the longitudinal direction X of the frame 1004 , and the first direction W is parallel to the transverse direction Y of the frame 1004 . Therefore, when the battery 200 is installed on the bracket 100 , the length direction of the battery 200 is parallel to the longitudinal direction X of the frame 1004 .

[0253] By arranging the first direction W of the bracket 100 perpendicular to the longitudinal direction X of the frame 1004, the batteries 200 can be arranged along the longitudinal direction X of the frame 1004. This prevents significant differences in the front-to-rear load of the frame 1004 due to changes in the number of batteries 200, thereby reducing the front-to-rear tilt of the vehicle. Furthermore, the symmetrical arrangement of the batteries 200 about the first surface 101 can better balance the left and right gravity of the frame 1004.

[0254] In some embodiments, the first direction W is parallel to the transverse direction Y of the frame 1004. When the bracket 100 is part of the frame body 30 of the frame 1004, the first side frame 111 of the frame 11 can be used as the crossbeam 32 of the frame body 30, and the second side frame 112 can be used as the longitudinal beam 31 of the frame body 30.

[0255] 13 and 14 , in some embodiments, the first direction W is parallel to the longitudinal direction X of the frame 1004 .

[0256] The first direction W is parallel to the longitudinal direction X of the frame 1004 , and the first direction W is perpendicular to the transverse direction Y of the frame 1004 . Therefore, when the battery 200 is installed on the bracket 100 , the length direction of the battery 200 is parallel to the transverse direction Y of the frame 1004 .

[0257] By arranging the first direction W of the bracket 100 parallel to the longitudinal direction X of the frame 1004, the batteries 200 can be arranged along the transverse direction Y of the frame 1004. This prevents significant differences in the left and right loads of the frame 1004 due to changes in the number of batteries 200, thereby reducing left-right tilt of the vehicle. Furthermore, arranging the batteries 200 symmetrically about the first surface 101 can better balance the front-to-back gravity of the frame 1004, thereby reducing the front-to-back tilt of the vehicle.

[0258] Please refer to Figures 5, 6 and 12. According to some embodiments of the present application, the present application provides a battery 200 for use with the bracket 100 described in any of the above embodiments. The battery 200 is provided with a battery replacement connector 21 for detachably connecting to the battery replacement interface 13.

[0259] The battery replacement connector 21 refers to a connector structure provided on the battery 200 for connecting to an external device, thereby supplying electrical energy to the outside or charging the battery 200 .

[0260] The battery 200 of the embodiment of the present application can be installed on the bracket 100 of the above embodiment to achieve flexible installation and replacement of the number of batteries 200.

[0261] In some embodiments, a groove 22 is provided on the battery 200 , and the groove 22 is used for receiving the support beam 12 in the corresponding installation area 16 .

[0262] The groove 22 refers to a slot structure provided on the battery 200 .

[0263] A groove 22 is provided on the battery 200 to allow at least a portion of the battery 200 to extend into the bracket 100 . When the capacity of the battery 200 is constant, the overall volume of the battery 200 after being installed in the bracket 100 can be reduced.

[0264] In some embodiments, when the opposite sides of the second mounting area 162 extend to two adjacent first mounting areas 161, the support beams 12 of the second mounting area 162 will be located in the two first mounting areas 161, while the support beams 12 of the first mounting area 161 will also be located in the second mounting area 162. This allows a groove 22 to be provided on the battery 200 to avoid the support beams 12. That is, when the battery 200 is installed in the second mounting area 162, the support beams 12 located in the second mounting area 162 will be placed in the groove 22. This allows the battery 200 to be extended into the frame 11, thereby reducing the overall thickness and occupying less space.

[0265] In some embodiments, the replacement connector includes an electrical connector 211. The electrical connector 211 refers to a connector provided on the battery 200 for connecting to an external device so that the battery 200 can supply power to the outside or charge the battery 200. The electrical connector 211 is provided so that the battery 200 is connected to the electrical interface 131 of the battery replacement interface 13.

[0266] In some embodiments, a cooling line is provided in the battery 200, and a pipe joint 212 is provided on the battery 200 to allow coolant to flow through the cooling line inside the battery 200 to dissipate heat from the battery 200. The replacement joint includes the pipe joint 212. The electrical connector 211 refers to a connector provided on the battery 200 for connecting to an external device so that the battery 200 can supply power to the outside or charge the battery 200.

[0270] Please refer to Figures 5 and 6 together. According to some embodiments of the present application, the present application provides a battery replacement method, which is used to replace the battery 200 of the bracket 100 described in any of the above embodiments.

[0271] The battery replacement method includes the following steps:

[0272] S1, receiving the number and position information of the current batteries 200 on the bracket 100, and the number of batteries 200 to be replaced;

[0273] Since the battery 200 on the bracket 100 is being replaced, it is necessary to determine the number and location of the batteries 200 currently installed on the bracket 100 to facilitate replacement of the batteries 200. Generally speaking, the device or equipment for replacing the batteries 200 on the bracket 100 can be called a battery replacement station. Of course, manual replacement of the batteries 200 is also possible.

[0274] The number of batteries 200 to be replaced is received so that the positions of the new batteries 200 on the bracket 100 are arranged according to the number of new batteries 200 to be replaced, so as to replace the batteries 200.

[0275] When using a battery swap station to replace batteries 200, the number and location information of the current batteries 200, as well as the number of batteries 200 to be replaced, can be sent to the battery swap station through interactive devices such as a tablet computer or a display on the power-consuming device using the bracket 100. Of course, the number and location information of the current batteries 200, as well as the number of batteries 200 to be replaced, can also be sent to the battery swap station through the user's mobile phone, tablet computer or other device.

[0276] In some embodiments, the information of the bracket 100 can be stored in the battery swap station, and the number and location information of the current batteries 200 on the bracket 100 and the number of batteries 200 to be replaced can be directly input on the interactive devices such as the tablet computer and display of the battery swap station, so that the battery swap station receives the number and location information of the current batteries 200 on the bracket 100 and the number of batteries 200 to be replaced.

[0277] S2. Determine that the number of batteries 200 to be replaced is equal to the number of batteries 200 on the bracket 100, and directly replace the batteries 200 on the bracket 100;

[0278] Since the number of batteries 200 to be replaced is equal to the number of batteries 200 on the bracket 100, when replacing the batteries 200, the new batteries 200 can be directly installed in the position of the original batteries 200. Therefore, the batteries 200 on the bracket 100 can be directly replaced without moving other components on the bracket 100.

[0279] S3. Determine that the number of batteries 200 to be replaced is not equal to the number of batteries 200 on the bracket 100, remove the batteries 200 on the bracket 100, and replace the same number of new batteries 200 on the bracket 100 according to the number of batteries 200 to be replaced.

[0280] Since the number of new batteries 200 that need to be replaced is not equal to the number of batteries 200 originally installed on the bracket 100, it is necessary to re-determine the installation position of the new batteries 200. Therefore, it is necessary to remove the batteries 200 on the bracket 100 to rearrange the position of the new batteries 200 and then install the new batteries 200.

[0281] The battery replacement method of the embodiment of the present application can realize the installation of different numbers of batteries 200 on the bracket 100, and make the bracket 100 as a whole symmetrical about the first surface 101 after the batteries 200 are installed, so that when in use, the weight of the bracket 100 on both sides of the first surface 101 is balanced, which is convenient for use.

[0282] In some embodiments, in the above-mentioned battery replacement method, step S3 can be adjusted as follows.

[0283] S31. The battery replacement interface 13 on the bracket 100 is slidably supported on the frame 11 along the first direction W; it is determined that the number of batteries 200 to be replaced is not equal to the number of batteries 200 on the bracket 100. After removing the batteries 200 on the bracket 100, push the battery replacement interface 13 to move to the position corresponding to the installation area 16 where the new batteries 200 are to be installed, and then install the new batteries 200 in the installation area 16.

[0284] The battery exchange interface 13 is supported by sliding on the frame 11 along the first direction W, and the battery exchange interface 13 can be moved along the first direction W on the frame 11, so as to move the battery exchange interface 13, so as to facilitate connecting the battery exchange interface 13 to the battery exchange connector 21 of the battery 200 when installing the battery 200.

[0285] By moving the battery replacement interface 13, the required number of new batteries 200 can be better installed on the bracket 100 symmetrically about the first surface 101, so that the weight of the bracket 100 with the new batteries 200 installed on both sides of the first surface 101 can be better balanced, and different numbers of batteries 200 can be better adapted to be installed on the bracket 100.

[0286] In some embodiments, in the above-mentioned battery replacement method, step S3 can be adjusted as follows.

[0287] S32. The battery replacement interface 13 on the bracket 100 is supported on the frame 11 by sliding along the first direction W; a driver 17 is provided on the bracket 100 to drive the battery replacement interface 13 to move, and it is determined that the number of batteries 200 to be replaced is not equal to the number of batteries 200 on the bracket 100. After removing the batteries 200 on the bracket 100, the driver 17 pushes the battery replacement interface 13 to move to the position corresponding to the installation area 16 where the new batteries 200 are to be installed, and then the new batteries 200 are installed in the installation area 16.

[0288] The battery exchange interface 13 is supported on the frame 11 by sliding along the first direction W, and a driver 17 is provided on the bracket 100 to move the battery exchange interface 13. The driver 17 refers to a linear module that can push the battery exchange interface 13 to move linearly.

[0289] Through the above steps, the driver 17 is used to move the battery replacement interface 13, so as to accurately move the battery replacement interface 13 to the set position for installing a new battery 200.

[0290] In some embodiments, in the above-mentioned battery replacement method, step S3 can be adjusted as follows.

[0291] S33, the battery exchange interface 13 on the bracket 100 is supported on the frame 11 by sliding along the first direction W; the battery exchange station is provided with a pusher for driving the battery exchange interface 13 to move. When it is determined that the number of batteries 200 to be replaced is not equal to the number of batteries 200 on the bracket 100, after removing the batteries 200 on the bracket 100, the pusher pushes the battery exchange interface 13 to move to the position corresponding to the installation area 16 where the new batteries 200 are to be installed, and then the new batteries 200 are installed in the installation area 16.

[0292] The battery swap interface 13 is supported on the frame 11 by sliding along the first direction W. A pusher may be provided on the battery swap station to move the battery swap interface 13. The pusher refers to a linear module that can push the battery swap interface 13 to move linearly.

[0293] Through the above steps, a pusher is set at the battery swap station, and the battery swap interface 13 is moved by the pusher, so that the battery swap interface 13 can be accurately moved to the set position to install the new battery 200. In addition, if a pusher is set at the battery swap station, there is no need to set a driver 17 on the bracket 100, which can further reduce the weight and cost of the bracket 100.

[0294] In some embodiments, in the above-mentioned battery replacement method, step S3 can also be adjusted as follows.

[0295] S34. The support beam 12 on the bracket 100 is slidably installed on the frame 11. It is determined that the number of batteries 200 to be replaced is not equal to the number of batteries 200 on the bracket 100. After removing the batteries 200 on the bracket 100, the support beam 12 is pushed to move to the corresponding positions on the opposite sides of the installation area 16 where the new batteries 200 are to be installed, and then the new batteries 200 are installed in the installation area 16.

[0296] The support beams 12 are slidably installed on the frame 11 , so that when the battery 200 is installed, the support beams 12 can be moved to opposite sides of the corresponding installation area 16 to support the battery 200 , thereby reducing the number of support beams 12 .

[0297] By moving the support beam 12 to the opposite sides of the installation area 16 where the new battery 200 needs to be installed, the battery 200 can be supported when the new battery 200 is installed.
