[0050] Please refer to Figure 2 , Figure 2 An exploded diagram of a battery provided for some embodiments of the present application. The battery 100 includes a battery case and a battery cell 20. In some embodiments, the battery case may include an upper cover 10 and a case 30, the upper cover 10 and the case 30 cover each other, and the upper cover 10 and the case 30 jointly define a receiving cavity for accommodating the battery cell 20. The case 30 may be a hollow structure with one end open, the upper cover 10 may be a plate-like structure, the upper cover 10 covers the open side of the case 30, so that the upper cover 10 and the case 30 jointly define a receiving cavity; the upper cover 10 and the case 30 may also be hollow structures with one side open, and the open side of the upper cover 10 covers the open side of the case 30.

In the battery 100, there can be multiple battery cells 20, and the multiple battery cells 20 can be connected in series, in parallel, or in mixed connection. Mixed connection means that the multiple battery cells 20 are both connected in series and in parallel. The multiple battery cells 20 can be directly connected in series, in parallel, or in mixed connection, and then the whole formed by the multiple battery cells 20 is accommodated in the box; of course, the battery 100 can also be a battery module formed by connecting multiple battery cells 20 in series, in parallel, or in mixed connection, and the multiple battery modules are then connected in series, in parallel, or in mixed connection to form a whole, and accommodated in the box. The battery 100 may also include other structures. For example, the battery 100 may also include a busbar component for realizing electrical connection between the multiple battery cells 20.

[0052] Each battery cell 20 may be a secondary battery cell or a primary battery cell, or a lithium-sulfur battery cell, a sodium-ion battery cell, or a magnesium-ion battery cell, but is not limited thereto. The battery cell 20 may be cylindrical, flat, rectangular, or in other shapes.

[0053] Please refer to Figure 4 , Figure 4 Schematic diagram of the exploded structure of a battery cell provided in some embodiments of the present application. A battery cell 20 refers to the smallest unit constituting a battery. The battery cell 20 includes an end cap 21, a housing 22, an electrode assembly 23 and other functional components.

[0054] The end cap 21 refers to a component that covers the opening of the shell 22 to isolate the internal environment of the battery cell 20 from the external environment. Without limitation, the shape of the end cap 21 can be adapted to the shape of the shell 22 to match the shell 22. Optionally, the end cap 21 can be made of a material with a certain hardness and strength (such as aluminum alloy), so that the end cap 21 is not easily deformed when squeezed and collided, so that the battery cell 20 can have a higher structural strength and the safety performance can also be improved. Functional components such as electrode terminals 26 can be provided on the end cap 21. The electrode terminal 26 can be used to electrically connect to the electrode assembly 23 for outputting or inputting electrical energy of the battery cell 20. In some embodiments, the end cap 21 can also be provided with a pressure relief mechanism for releasing the internal pressure when the internal pressure or temperature of the battery cell 20 reaches a threshold. The material of the end cap 21 can also be a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application do not impose special restrictions on this. In some embodiments, an insulating member may be provided inside the end cap 21, and the insulating member may be used to isolate the electrical connection components in the housing 22 from the end cap 21 to reduce the risk of short circuit. For example, the insulating member may be plastic, rubber, or the like.

[0055] The shell 22 is a component used to cooperate with the end cap 21 to form the internal environment of the battery cell 20. The formed internal environment can be used to accommodate the electrode assembly 23, the electrolyte and other components. The shell 22 and the end cap 21 can be independent components. An opening can be set on the shell 22, and the internal environment of the battery cell 20 is formed by covering the opening with the end cap 21 at the opening. In some examples, the shell 22 is a hollow structure with an opening on one side, and the end cap 21 is one and covers the opening of the shell 22. In other examples, the shell 22 is a hollow structure with openings on both sides, and there are two end caps 21, and the two end caps 21 cover the two openings of the shell 22 respectively. Without limitation, the end cap 21 and the shell 22 can also be integrated. Specifically, the end cap 21 and the shell 22 can form a common connection surface before other components are put into the shell, and when it is necessary to encapsulate the interior of the shell 22, the end cap 21 covers the shell 22. The shell 22 can be of various shapes and sizes, such as a rectangular parallelepiped, a cylindrical shape, a hexagonal prism, etc. Specifically, the shape of the shell 22 can be determined according to the specific shape and size of the electrode assembly 23. The shell 22 can be made of various materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiment of the present application does not impose any special restrictions on this.

[0056] The electrode assembly 23 is a component in the battery cell 20 where electrochemical reactions occur. One or more electrode assemblies 23 may be included in the housing 22. The electrode assembly 23 is mainly formed by winding or stacking positive and negative electrode sheets, and a separator is usually provided between the positive and negative electrode sheets. The parts of the positive and negative electrode sheets with active materials constitute the main body of the electrode assembly 23, and the parts of the positive and negative electrode sheets without active materials each constitute a tab. The positive tab and the negative tab may be located together at one end of the main body or at both ends of the main body, respectively. During the charge and discharge process of the battery, the positive active material and the negative active material react with the electrolyte, and the tabs connect the electrode terminals 26 to form a current loop.

[0057] There are many types of new energy vehicles, and the arrangement of batteries at the bottom of the vehicle is not uniform. In the battery swap industry, battery transportation mostly uses battery transport devices such as RGV (Rail Guided Vehicle) carts. The battery transport device needs to consider the movement in two different directions, the X direction and the Y direction, to match the battery position of the vehicle. Since there are many electrical components in battery transport devices such as RGV carts, cables and other wiring are easily damaged following the movement of the battery transport device. Generally, a winder mechanism is used, and the winder introduces a wire rope. The winder mechanism is difficult to solve the synchronization problem between the movement of the battery transport device and the winder, which makes it easy for the wire rope to break and damage the cable, and the battery replacement cost increases. In addition, the winder requires additional power, which will also increase the cost of battery replacement.

[0058] In order to solve the above-mentioned technical problems, an embodiment of the present application provides a battery transportation device, the battery transportation device includes a track device and a battery transportation device, the battery transportation device includes a base plate, a main control mechanism and a protection mechanism, the base plate is used to move along a first direction or a second direction relative to the track device, the main control mechanism is fixed on the base plate, the protection mechanism includes a first protection component and a second protection component connected to each other, the first protection component is fixed to the track device, the second protection component extends to the main control mechanism, and the wiring of the main control mechanism passes through the second protection component and the first protection component in sequence; the second protection component is fixed to the base plate, and the base plate is slidably connected to the first protection component along the second direction; wherein the first direction and the second direction are arranged to intersect.

[0059] In the above scheme, the wiring led out from the main control mechanism is protected by the first protection component and the second protection component. When the base plate moves along the first direction relative to the track device, the first protection component and the second protection component move with the base plate. Since the base plate is slidably connected to the first protection component along the second direction, when the base plate moves along the second direction relative to the track device, the second protection component moves with the base plate, and the first protection component remains stationary, thereby realizing that when the battery transport equipment moves in two different directions, the first direction and the second direction, the wiring can be protected, the risk of damage to the wiring is reduced, and the cost of battery replacement is reduced.

[0060] Figure 5 It is a schematic diagram of the structure of the battery transportation equipment provided in some embodiments of the present application.

[0061] like Figure 5 As shown, in the first aspect, the embodiment of the present application provides a battery transportation device 500, the battery transportation device 500 includes a track device 40 and a battery transportation device 50, the battery transportation device 50 includes a base plate 51, a main control mechanism 52 and a protection mechanism 60, the base plate 51 is used to move relative to the track device 40 along the first direction X or the second direction Y, the main control mechanism 52 is fixed on the base plate 51, the protection mechanism 60 includes a first protection component 61 and a second protection component 62 connected to each other, the first protection component 61 is fixed to the track device 40, the second protection component 62 extends to the main control mechanism 52, and the wiring of the main control mechanism 52 passes through the second protection component 62 and the first protection component 61 in sequence; the second protection component 62 is fixed to the base plate 51, and the base plate 51 is slidably connected to the first protection component 61 along the second direction Y; wherein the first direction X and the second direction Y are arranged to intersect.

[0062] When replacing the battery, the removed old battery 100 or the new battery 100 to be replaced can be placed on the bottom plate 51, or a positioning mechanism 53 can be set on the bottom plate 51, and the battery 100 can be placed on the positioning mechanism 53. The track device 40 can be provided with tracks in different directions so that the bottom plate 51 can be moved in different directions.

[0063] The main control mechanism 52 may include a housing and a plurality of electrical components disposed inside the housing, and the wiring of the plurality of electrical components is led out of the housing and passes through the second protection component 62 and the first protection component 61. For example, a power cable passes through the second protection component 62 and the first protection component 61 and is plugged into a socket, thereby providing power to the battery transport device 50.

[0064] The interior of the first protection mechanism 60 and the interior of the second protection mechanism 60 are both provided with passages for the main control mechanism 52 to pass through. The first direction X and the second direction Y may be perpendicular to each other. One end of the first protection component 61 may be fixed to the track device 40, and the other end may be fixed to the second protection component 62. Parts of the first protection component 61 and parts of the second protection component 62 may be flexible, so that when the bottom plate 51 moves along the first direction X, the flexible part of the first protection component 61 can be bent and moved, and the flexible part of the second protection component 62 can be bent and moved.

[0065] In the above scheme, the wiring led out from the main control mechanism 52 is protected by the first protection component 61 and the second protection component 62. When the base plate 51 moves along the first direction X relative to the track device 40, the first protection component 61 and the second protection component 62 follow the base plate 51 to move; since the base plate 51 is slidably connected to the first protection component 61 along the second direction Y, when the base plate 51 moves along the second direction Y relative to the track device 40, the second protection component 62 follows the base plate 51 to move, and the first protection component 61 remains stationary, thereby achieving the battery transportation equipment 500 moving in the first direction X and the second direction Y. The wiring can be protected and the risk of wiring damage is reduced, thereby reducing the cost of battery replacement.

[0066] In some embodiments, the track device 40 includes a base 41 and first tracks 42 respectively disposed on the base 41 , the first tracks 42 extend along the first direction X, the bottom plate 51 is rollably connected to the first tracks 42 , and the first protection component 61 is fixed to the base 41 .

[0067] Rollers 411 may be provided on the bottom plate 51, and the rollers 411 may be used to roll forward on the first rails 42. Two first rails 42 arranged at intervals may be provided on the base 41, and four rollers 411 may be provided on the bottom plate 51, with two rollers 411 along the first direction X, and each first rail 42 corresponds to two rollers 411.

[0068] In the above solution, the battery transport device 50 can roll forward on the first track 42, thereby improving the stability of the battery transport device 50 when moving along the first direction X.

[0069] In some embodiments, the track device 40 further includes a second track (not shown) disposed on the base 41 , the second track extends along the second direction Y, and the bottom plate 51 is slidably connected to the second track.

[0070] First, the bottom plate 51 can roll along the first track 42. When it is necessary to switch to the second track, the roller 411 of the bottom plate 51 is pushed to the second track. At this time, the roller 411 of the bottom plate 51 can slide along the second track but does not roll.

[0071] In the above solution, the battery transport device 50 can slide forward on the second track, thereby improving the stability of the battery transport device 50 when moving along the second direction Y.

[0072] Figure 6 It is a schematic diagram of the structure of battery transportation equipment provided in other embodiments of the present application.

[0073] like Figure 6 As shown, in some embodiments, the first protection component 61 includes a first rigid portion 611 and a first flexible portion 612, one end of the first flexible portion 612 is fixed to the base plate 51, and the other end of the first flexible portion 612 is fixed to the first rigid portion 611, and the wiring of the main control mechanism 52 passes through the first rigid portion 611 and the first flexible portion 612 in sequence.

[0074] The first flexible portion 612 may be a flexible structure such as a drag chain. One end of the first flexible portion 612 is fixed to the base 41, and the other end is bent upward and connected to the first rigid portion 611. When the bottom plate 51 moves along the first direction X, the first rigid portion 611 also moves along the first direction X with the other end of the first flexible portion 612.

[0075] In the above scheme, when the base plate 51 moves along the first direction X, the first rigid part follows the base plate 51, and the end of the first flexible part 612 away from the first rigid part 611 follows the base plate 51, thereby further preventing the wiring from being damaged during the movement and reducing the battery replacement cost.

[0076] In some embodiments, the second protection component 62 includes a second flexible portion 622 and a second rigid portion 621, one end of the second flexible portion 622 is fixed to the first rigid portion 611, the other end of the second flexible portion 622 is fixed to the second rigid portion 621, the second rigid portion 621 extends away from one end of the second flexible portion 622 to the main control mechanism 52, and the wiring of the main control mechanism 52 passes through the second rigid portion 621 and the second flexible portion 622 in sequence.

[0077] The second flexible portion 622 may be a flexible structure such as a drag chain. One end of the second flexible portion 622 is fixed to the first rigid portion 611, and the other end is bent upward and connected to the second rigid portion 621. When the bottom plate 51 moves along the second direction Y, the second rigid portion 621 also moves along the second direction Y with the other end of the second flexible portion 622.

[0078] In the above scheme, when the base plate 51 moves along the second direction Y, the second rigid part 621 will move with the base plate 51, and the end of the second flexible part 622 away from the first rigid part 611 will also move with the base plate 51, thereby further preventing the wiring from being damaged during the movement and reducing the battery replacement cost.

The end of the first flexible portion 612 is bent in the first receiving area 6113 and fixed to the first rigid portion 611 by adhesive or bolts.

[0082] In the above solution, by dividing the first rigid portion 611 into the first bending section 6111 and the first horizontal section 6112 , the end of the first flexible portion 612 is accommodated in the first accommodating area 6113 , so that the structure of the battery transport device 50 is compact and the space utilization of the battery transport device 50 is improved.

[0083] In some embodiments, the second rigid portion 621 includes a second bending section 6211 and a second horizontal section 6212, the second horizontal section 6212 extends along the first direction X, the second flexible portion 622 is connected to the second bending section 6211, the second horizontal section 6212 is fixed to the bottom plate 51, the second bending section 6211 forms a second receiving area 6213, and the end of the first flexible portion 612 and the first bending section 6111 are received in the second receiving area 6213.

[0084] The second bending section 6211 may include two bending areas. For example, after the second bending section 6211 is connected to the second flexible section, it first bends toward the main control mechanism 52 and then bends downward. The first bending section 6111 of the first rigid portion 611 and the end of the first flexible portion 612 are both accommodated in the second accommodation area 6213 of the second bending section 6211.

[0085] In the above scheme, by dividing the second rigid portion 621 into a second bending section 6211 and a second horizontal section 6212, the end of the first flexible portion 612 and the first bending section 6111 are accommodated in the second accommodating area 6213, so that the structure of the battery transportation device 50 is compact and the space utilization rate of the battery transportation device 50 is improved.
