[0051] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0052] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0053] The battery tray provided herein has grooves and protrusions on the opposing surfaces of the lifting lug and the chute, respectively, and the chute has multiple grooves / protrusions. When the protrusions are located within the grooves, the lifting lug and the side rail are relatively fixed; when the protrusions are located outside the grooves, the lifting lug and the side rail can move relative to each other to adjust the position of the lifting lug on the side rail.

[0054] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0055] The present application provides an electrical device, which may include, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery-powered vehicle, an electric car, a ship, a spacecraft, and the like. The electric toy may include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, and the spacecraft may include airplanes, rockets, space shuttles, and spacecraft. The electric car may include a pure electric car, a hybrid electric car, or an extended-range electric car.

[0056] The aforementioned electrical equipment includes a battery pack for storing and providing electrical energy. For example, a lithium-ion battery pack has high cell specific energy and low internal resistance, resulting in improved battery life. The present application is not limited to a specific type of battery pack; the battery pack may be selected as needed.

[0057] For example, a battery pack is provided inside the electric vehicle, and the battery pack can be provided at the bottom, head, or tail of the electric vehicle. The battery pack can be used to power the electric vehicle, for example, the battery pack can serve as the operating power source of the electric vehicle. The electric vehicle may also include a controller and a motor, and the controller is used to control the battery pack to power the motor, for example, for the starting, navigation, and operating power requirements of the electric vehicle during driving. In some embodiments of the present application, the battery pack can serve not only as the operating power source of the electric vehicle, but also as the driving power source of the electric vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the electric vehicle.

[0058] A battery pack includes battery cells, which are the smallest units that make up the battery pack. A battery pack can contain multiple battery cells. Multiple battery cells can be connected in series, parallel, or in a hybrid configuration. A hybrid configuration refers to a combination of series and parallel connections. Multiple battery cells can be combined to form a battery module, which in turn is combined with several battery modules to form a battery pack. This is called a CTM (Cell to Module) battery pack. Battery cells can also be directly combined to form a battery pack, which is called a CTP (Cell to Pack) battery pack. In other examples, the battery pack can also be called a CTB (Cell to Body) battery pack.

[0059] The battery pack also includes the battery tray, see Figures 1 to 12The battery tray is used to carry battery cells. The battery tray includes a tray body 10 and a lifting lug 20. The tray body 10 includes a side beam 11, and a slide groove 30 is formed on the surface of the side beam 11. The lifting lug 20 is disposed within the slide groove 30. One of the first surface of the lifting lug 20 and the second surface of the slide groove 30 is provided with a groove 50, and the other is provided with a protrusion 40. The first surface and the second surface are opposite to each other, and the protrusion 40 is adapted to fit the groove 50. There are multiple grooves 50 or protrusions 40 on the second surface, and they are arranged along the extension direction of the slide groove 30.

[0060] The battery tray has a first usage state and a second usage state. In the first usage state, the protrusion 40 is located outside the groove 50, and the lifting ear 20 can move along the extension direction of the slide 30; in the second usage state, the protrusion 40 is embedded in the groove 50, and the lifting ear 20 is fixed relative to the side beam 11. With this arrangement, in the second usage state, the lifting ear 20 is fixed relative to the side beam 11; in the first usage state, the position of the lifting ear 20 on the side beam 11 can be adjusted so that the lifting ear 20 can be located at different positions on the side beam 11. The installation position of the lifting ear 20 relative to the tray body 10 can be adjusted accordingly according to assembly requirements. There is no need to develop battery trays for different lifting points, which reduces development costs and the cost of mold opening for the tray.

[0061] See Figure 1 and Figure 2 The tray body 10 includes a bottom plate 12, side beams 11, and expansion beams 13. The side beams 11 are arranged on one side of the bottom plate 12 and form a placement groove with the bottom plate 12. The expansion beams 13 are fixedly arranged in the placement groove. The expansion beams 13 and the side beams 11 are opposite to each other and spaced apart. The bottom plate 12 can be a flat plate to stably support the battery cells.

[0062] There can be multiple side beams 11, and the multiple side beams 11 are connected end to end in sequence, that is, the multiple side beams 11 form a ring. The side beams 11 also surround the bottom plate 12, and the structure formed by the multiple side beams 11 is adapted to the bottom plate 12, so that the pallet body 10 is not easily deformed when squeezed or collided, thereby improving the structural strength of the pallet body 10. The side beams 11 and the bottom plate 12 can be independent of each other, and the side beams 11 and the bottom plate 12 can also be integrally formed. The shape and size of the placement groove are not limited. For example, the placement groove is rectangular, cylindrical, hexagonal, etc.

[0063] In some possible embodiments, the side beam 11 includes a first beam and a second beam disposed opposite each other. The first beam and the second beam are located on the same side of the bottom plate 12 and at opposite ends of the bottom plate 12. For example, the first beam and the second beam are disposed opposite each other along the length of the bottom plate 12. The side beam 11 also includes a third beam and a fourth beam. The third beam connects one end of the first beam and one end of the second beam, and the fourth beam connects the other end of the first beam and the other end of the second beam. In other words, the first beam, the third beam, the second beam, and the fourth beam are connected in sequence. The third beam and the fourth beam are disposed opposite each other along the width of the bottom plate 12.

[0064] See Figure 1 and Figure 3 The side beam 11 has a sliding groove 30 on its surface for receiving the lifting lug 20. The sliding groove 30 is disposed outside the placement slot, and extends in the same direction as the side beam 11, and also in the longitudinal direction of the sliding groove 30. In the example where the side beam 11 includes a first beam body and a second beam body, the sliding groove 30 is formed on surfaces of the first beam body and the second beam body facing away from each other. This allows the lifting lug 20 to be disposed on both sides of the pallet body 10, thereby improving the stability of the pallet body 10 during transportation.

[0065] For some possible examples, see Figure 7 The chute 30 includes a first chute body 31 and a second chute body 32 that are interconnected. The first chute body 31 and the second chute body 32 extend in the same direction. The first chute body 31 is formed on the surface of the side beam 11, and the second chute body 32 is located on the side of the first chute body 31 away from the surface of the side beam 11. The width of the second chute body 32 is greater than that of the first chute body 31.

[0066] The second trough 32 is connected to the first trough 31, and the second trough 32 is located inside the side beam 11 relative to the first trough 31. Figure 7 As shown, the opening of the first slot 31 is provided on the surface of the side beam 11, and one end of the first slot 31 away from the side beam 11 (i.e., the bottom of the first slot 31) is connected to the second slot 32. In some possible examples, the first slot 31 is provided on the wall of the second slot 32 adjacent to the surface of the side beam 11, and the first slot 31 extends to the surface of the side beam 11.

[0067] The width of the second trough 32 is greater than that of the first trough 31. The width direction is perpendicular to the extension direction and the depth direction. The depth direction is the direction perpendicular to the surface of the side beam 11. The width of the second trough 32 is greater than the width of the first trough 31. In this way, the wider second trough 32 is located further inside the side beam 11. The first trough 31 can form a limit for the lifting lug 20, reducing the lifting lug 20 from detaching from the second trough 32. Figure 7As shown, with a plane perpendicular to the extending direction of the chute 30 as a cross section, the cross section of the chute 30 is T-shaped.

[0068] The expansion beam 13 is located within the storage slot, opposite and spaced from the side beam 11. As the battery cells within the storage slot expand, they compress the expansion beam 13, which is secured to the storage slot via a detachable connection. The materials for the base plate 12, side beam 11, and expansion beam 13 include copper, iron, aluminum, stainless steel, aluminum alloy, plastic, and other materials, though these are not limited in this embodiment.

[0069] See Figure 1 、 Figure 3 and Figure 4 The lifting lug 20 is disposed within the chute 30 and extends outside the chute 30. The lifting lug 20 outside the chute 30 is provided with a through hole 24 for transportation. The first surface of the lifting lug 20 is disposed opposite the lifting lug 20. One of the first and second surfaces is provided with a groove 50, and the other is provided with a protrusion 40. Exemplarily, the first surface is provided with the groove 50 and the second surface is provided with the protrusion 40; in another exemplary embodiment, the first surface is provided with the protrusion 40 and the second surface is provided with the groove 50.

[0070] The protrusion 40 is adapted to fit into the groove 50 so that the protrusion 40 can be embedded in the groove 50, so that the ear 20 can be fixed to the tray body 10. At least one of the protrusion 40 and the groove 50 is provided in plurality, and the plurality of grooves 50 / protrusions 40 are provided on the second surface of the chute 30 and along the extending direction of the chute 30, so that the ear 20 can be provided at different positions in the chute 30 in the second use state.

[0071] In some possible examples, the first surface of the lifting ear 20 is provided with at least one groove 50 , and the second surface of the sliding groove 30 is provided with a plurality of protrusions 40 , which are arranged in sequence along the extension direction of the sliding groove 30 .

[0072] In some other possible examples, the first surface of the lifting ear 20 is provided with at least one protrusion 40, and the second surface of the chute 30 is provided with a plurality of grooves 50, and the plurality of grooves 50 are arranged in sequence along the extension direction of the chute 30. Figure 4 and Figure 5 As shown, the first surface of the ear 20 is provided with a plurality of protrusions 40, which can be arranged in an array, and the second surface of the slide groove 30 is provided with a plurality of grooves 50, which can be arranged in an array, which can improve the reliability of the connection between the ear 20 and the pallet body 10 in the second usage state.

[0073] In some possible examples, the protrusion 40 is shaped like a cylinder, an elliptical cylinder, a diamond-shaped cylinder, a triangular cylinder, a rectangular cylinder, a cone, a truncated cone, an elongated strip, or a wavy shape. For example, the protrusion 40 is a cube. When multiple protrusions 40 are provided, the multiple protrusions 40 have the same size. The shape of the groove 50 is compatible with the shape of the protrusion 40. For example, the shape of the groove 50 is a cube. When multiple grooves 50 are provided, the multiple grooves 50 have the same shape.

[0074] The size of the groove 50 and the size of the protrusion 40 are also adapted to allow the groove 50 and the protrusion 40 to fit together. The shape, number, and size of the grooves 50 and protrusion 40 are adjusted according to the size of the battery pack. For example, multiple grooves 50 and protrusions 40 are provided, each of which is a 2mm×2mm×2mm cube-shaped groove 50, with each protrusion 40 fully matching the corresponding groove 50.

[0075] Continue reading Figure 1 、 Figure 3 and Figure 4 The lifting lug 20 includes a body 21 and a mounting portion. The body 21 is disposed outside the chute 30; the mounting portion is connected to the body 21 and disposed inside the chute 30. The body 21 may be block-shaped and provided with a through hole 24. The through hole 24 may be a straight through hole 24 or a stepped hole. In both the first and second usage states, the body 21 is disposed outside the chute 30. The through hole 24 facilitates the connection structure for transporting the battery tray. The battery tray can be lifted through the through hole 24 to lift and transport the battery pack.

[0076] The mounting portion is connected to the body 21, with one end of the mounting portion connected to one end of the body 21. The mounting portion can be integrally formed with the body 21, and both the mounting portion and the body 21 can be made of aluminum, for example. The mounting portion is disposed within the chute 30. For example, the mounting portion can be inserted into the chute 30 through the opening of the chute 30. The mounting portion can rotate within the chute 30. By cooperating with the chute 30, the mounting portion can be rotated to different angles to retain the mounting portion within the chute 30, preventing the lifting lug 20 from disengaging from the chute 30.

[0077] In some possible exemplary embodiments, the surface of the mounting portion facing the bottom wall of the slide groove 30 is the first surface of the lifting ear 20, and a plurality of protrusions 40 are provided on the first surface; the bottom wall of the slide groove 30 is the second surface of the slide groove 30, and a plurality of grooves 50 are provided on the second surface to facilitate the processing of the protrusions 40 and the grooves 50, and also to facilitate the embedding of the protrusions 40 into the grooves 50. For example, after the grooves 50 and the protrusions 40 are aligned, the protrusions 40 can be embedded into the grooves 50 by pushing the lifting ear 20 horizontally.

[0078] The bottom wall of the chute 30 is directly opposite the opening of the chute 30. The bottom wall of the chute 30 is, for example, the wall of the second trough 32 away from the first channel. The surface of the mounting portion facing the bottom wall of the chute 30 is also the surface of the mounting portion away from the end of the body 21. In other examples, other wall surfaces of the chute 30 may also be provided with protrusions 40 / grooves 50, and the corresponding surfaces of the mounting portion may be provided with grooves 50 / protrusions 40. This embodiment of the present application is not limited to this.

[0079] Based on the above examples, in some possible implementations, multiple grooves 50 are arranged in an array; and / or multiple protrusions 40 are arranged in an array, so that the multiple grooves 50 are arranged regularly and / or regularly, which facilitates assembly. In the second usage state, the array formed by the multiple grooves 50 and the array formed by the multiple protrusions 40 are the same.

[0080] In some possible examples, multiple grooves 50 are arranged in an array on the second surface, for example, distributed throughout the entire second surface; and multiple protrusions 40 are arranged in an array on the first surface, for example, distributed throughout the entire first surface. The spacing of the multiple grooves 50 along the extension direction of the chute 30 is different from the spacing along the width direction of the chute 30, that is, the row spacing and column spacing formed by the multiple grooves 50 are different. Thus, by rotating the lifting lug 20 so that in the first usage state, the array formed by the multiple protrusions 40 and the array formed by the multiple grooves 50 are 90° apart, the grooves 50 and the protrusions 40 can be prevented from interlocking. Of course, in the first usage state, the array formed by the multiple protrusions 40 and the array formed by the multiple grooves 50 can also be consistent.

[0081] Continue reading Figures 4 to 6 The mounting portion includes a moving block 23 and a connecting rod 22. The moving block 23 is arranged in the second slot 32. The connecting rod 22 is connected between the moving block 23 and the main body 21, and at least part of the connecting rod 22 is located in the first slot 31. The moving block 23 can be a rectangular parallelepiped or other blocks with different lengths and widths. One end of the connecting rod 22 is connected to the moving block 23, and the other end is connected to the main body 21. The connecting rod 22 can connect the surfaces of the main body 21 and the moving block 23 that are opposite to each other, that is, the main body 21, the connecting rod 22, and the moving block 23 are connected in sequence. The connecting rod 22, the main body 21 and the moving block 23 can be integrated, and the connecting rod 22 can be a cylinder, an elliptical cylinder or a rectangular cylinder.

[0082] The moving block 23 is located in the second groove 32 and is adapted to the second groove 32. For example, part of the surface of the moving block 23 contacts part of the wall of the second groove 32. Part or all of the connecting rod 22 is located in the first groove 31 and may not contact the wall of the first groove 31.

[0083] In some possible examples, the length of the moving block 23 is greater than the width of the first slot 31, and the width of the moving block 23 is less than the width of the first slot 31; in the second use state, the length direction of the moving block 23 is perpendicular to the extension direction of the second slot 32. Figure 4 As shown, in the end face of the moving block 23 away from the connecting rod 22, the long side direction of the moving block 23 is the length direction (X direction) of the moving block 23, the short side direction of the moving block 23 is the width direction (Y direction) of the moving block 23, and the direction of the moving block 23 away from the connecting rod 22 is the thickness direction (i.e., height direction) of the moving block 23.

[0084] The length of the moving block 23 is greater than the width of the first trough 31, and the width of the moving block 23 is less than the width of the first trough 31. In this way, the moving block 23 can enter the second trough 32 from the first trough 31 with its length parallel to the extension direction of the first trough 31 and can rotate in the second trough 32. The moving block 23 rotates in the second trough 32 until its length becomes perpendicular to the extension direction of the second trough 32. At this time, the moving block 23 cannot pass through the first trough 31, thereby confining the moving block 23 in the second trough 32 and preventing the lifting lug 20 from disengaging from the chute 30.

[0085] In the second usage state, the length direction of the movable block 23 is perpendicular to the extension direction of the second slot body 32. In this way, in addition to the fit and fixation between the groove 50 and the protrusion 40, the movable block 23 will not be separated from the second slot body 32, which can ensure the firmness of the connection between the lifting ear 20 and the side beam 11 in the second usage state.

[0086] It is understood that, in the first usage state, the length direction of the moving block 23 is parallel to the extension direction of the second slot body 32, that is, the moving block 23 can move in the second slot body 32 with its length direction parallel to the extension direction of the second slot body 32. Alternatively, in the first usage state, the length direction of the moving block 23 is perpendicular to the extension direction of the second slot body 32, that is, the moving block 23 can move in the second slot body 32 with its length direction perpendicular to the extension direction of the second slot body 32, thereby ensuring that the lifting lug 20 does not fall out of the chute 30 when moving.

[0087] In some possible examples, the body 21 is provided with a through hole 24. In the first use state, the axis of the through hole 24 is parallel or perpendicular to the extension direction of the slide groove 30. In the second use state, the axis of the through hole 24 is perpendicular to the extension direction of the slide groove 30. Figure 7 and Figure 8When the lifting lug 20 and the side beam 11 are relatively fixed, that is, in the second operating state, the axis of the through hole 24 is perpendicular to the extension direction of the chute 30, so that the through hole 24 is in a vertical state. When the lifting lug 20 moves within the side beam 11, that is, in the first operating state, the axis of the through hole 24 can be perpendicular to the extension direction of the chute 30, so that the through hole 24 is in a vertical state; the axis of the through hole 24 can also be parallel to the extension direction of the chute 30, so that the through hole 24 is in a horizontal state.

[0088] In order to further improve the reliability of the connection between the lifting lug 20 and the side beam 11, the lifting lug 20 is further welded to the side beam 11 in the second use state. Figure 7 As shown in Figure A, both sides of the body 21 of the lifting lug 20 are welded to the side beam 11. It is understood that in the second operating state, after the lifting lug 20 and the side beam 11 are welded, the second operating state cannot be switched to the first operating state. In the second operating state, the lifting lug 20 and the side beam 11 are not welded, and the second and first operating states can be switched freely.

[0089] In the example where the side beam 11 includes a first beam body and a second beam body disposed opposite each other, a chute 30 is provided on surfaces of the first beam body and the second beam body facing away from each other. Each chute 30 is provided with at least two lifting lugs 20. For example, each chute 30 is provided with two lifting lugs 20. This allows the side beam 11 to have two through holes 24 on each side for lifting, thereby improving the stability of the battery tray during transportation. Thermal insulation foam may also be provided on the side beam 11.

[0090] See Figures 9 to 12 In some possible examples, the assembly process of the lifting lug 20 and the side beam 11 is as follows:

[0091] The length direction of the moving block 23 of the lifting ear 20 is parallel to the extension direction of the slide groove 30, and the lifting ear 20 is placed horizontally. At this time, the axis of the through hole 24 is horizontal, that is, the main body 21 and the pallet main body 10 are in a vertical state, forming the first usage state; adjust the position of the lifting ear 20 in the slide groove 30 so that the through hole 24 is adjusted to a position that cooperates with the entire vehicle for assembly; rotate the lifting ear 20 90 degrees, and the length direction of the moving block 23 of the lifting ear 20 is perpendicular to the extension direction of the slide groove 30. At this time, the axis of the through hole 24 is horizontal, that is, the main body 21 and the pallet main body 10 are in a parallel state; embed the grooves 50 and the protrusions 40 of the lifting ear 20 and the slide groove 30 into engagement, thereby fixing the position of the lifting ear 20 on the side beam 11, and at this time forming the second usage state; weld the main body 21 of the lifting ear 20 to the side beam 11 to strengthen the connection strength between the lifting ear 20 and the pallet side beam 11.

[0092] In some possible examples, the assembly process of the lifting eye 20 and the side beam 11 is as follows:

[0093] The length direction of the moving block 23 of the lifting ear 20 is parallel to the extension direction of the slide slot 30, and the lifting ear 20 is placed horizontally. At this time, the axis of the through hole 24 is horizontal, that is, the main body 21 and the pallet main body 10 are in a vertical state; the lifting ear 20 is rotated 90 degrees, and the length direction of the moving block 23 of the lifting ear 20 is perpendicular to the extension direction of the slide slot 30. At this time, the axis of the through hole 24 is horizontal, that is, the main body 21 and the pallet main body 10 are in a parallel state, forming the first usage state; adjust the position of the lifting ear 20 in the slide slot 30 so that the through hole 24 is adjusted to a position that cooperates with the entire vehicle; embed the grooves 50 and the protrusions 40 of the lifting ear 20 and the slide slot 30 into bite, thereby fixing the position of the lifting ear 20 on the side beam 11, and then forming the second usage state; weld the main body 21 of the lifting ear 20 to the side beam 11 to strengthen the connection strength between the lifting ear 20 and the pallet side beam 11

[0094] The battery tray provided in an embodiment of the present application includes: a tray body 10 and a lifting lug 20. The tray body 10 includes a side beam 11, and a sliding groove 30 is defined on the surface of the side beam 11. The lifting lug 20 is disposed within the sliding groove 30. One of the first surface of the lifting lug 20 and the second surface of the sliding groove 30 is provided with a groove 50, and the other is provided with a protrusion 40. The first surface and the second surface are opposite each other, and the protrusion 40 is adapted to fit within the groove 50. A plurality of grooves 50 or protrusions 40 are provided on the second surface and are arranged along the extension direction of the sliding groove 30. In a first use state, the protrusion 40 is located outside the groove 50, and the lifting lug 20 is movable along the extension direction of the sliding groove 30. In a second use state, the protrusion 40 is engaged within the groove 50, and the lifting lug 20 is fixed relative to the side beam 11. This allows the lifting lug 20 to be positioned in the corresponding position of the battery tray according to the vehicle's lifting requirements, thereby improving the adaptability of the battery tray and reducing the development cost of the battery tray.
