[0039] Figure 1 A structural schematic diagram of a battery tray provided by an embodiment of the present application, Figure 2 An explosion schematic diagram of a battery tray provided by an embodiment of the present application, and Figure 1 And Figure 2 In some embodiments, the battery tray comprises a bottom plate 10, a first positioning plate 20 and a second positioning plate 30. Among them, the bottom plate 10, the first positioning plate 20 and the second positioning plate 30 are sequentially stacked along the thickness direction of the bottom plate 10. Or, the bottom plate 10, the first positioning plate 20 and the second positioning plate 30 are arranged in parallel, and the first positioning plate 20 is located between the bottom plate 10 and the second positioning plate 30.

[0040] The bottom plate 10 and the first positioning plate 20 are connected, and the "connection" can mean detachable connection or non-detachable connection, and the first positioning plate 20 and the second positioning plate 30 are detachably connected. The above-mentioned "detachable connection" includes but is not limited to clamping, connecting by screws or connecting by a strap and the like. In the above-mentioned connection mode, the corresponding two structural members can be separated without being damaged, and can be reassembled into an integral whole if necessary. The above-mentioned "non-detachable connection" includes but is not limited to welding, riveting and the like.

[0041] Please continue to refer to Figure 2 The first positioning plate 20 has a plurality of first positioning holes 201 for accommodating batteries. Optionally, the battery is a cylindrical battery. In the specific arrangement of the first positioning hole 201, the first positioning hole 201 can be a circular hole, a rectangular hole or a hole of other shapes, which will not be enumerated one by one in the present application. The first positioning hole 201 can be a through hole penetrating the thickness direction of the first positioning plate 20, or a blind hole. In the specific arrangement of the above-mentioned plurality of first positioning holes 201, the plurality of first positioning holes 201 can be randomly arranged, or arranged in a matrix, or arranged in other arrangement rules.

[0042] The second positioning plate 30 has a plurality of second positioning holes 301, which are also used to accommodate the battery. In the specific arrangement of the second positioning holes 301, the arrangement mode of the first positioning holes 201 can be referred to. For example, the second positioning holes 301 can be circular holes, rectangular holes, or holes of other shapes. The second positioning holes 301 can be arranged randomly, in a matrix, or in other arrangement rules. It should be noted that the second positioning holes 301 penetrate the second positioning plate 30 in the thickness direction of the second positioning plate 30. In other words, the second positioning holes 301 are through holes penetrating the thickness direction of the second positioning plate 30.

[0043] Regarding the relationship between the first positioning holes 201 and the second positioning holes 301, in the specific arrangement, each second positioning hole 301 corresponds to one first positioning hole 201, and any two second positioning holes 301 correspond to different first positioning holes 201, respectively. For each second positioning hole 301, the orthographic projection of the second positioning hole 301 on the plane where the support plate 10 is located and the orthographic projection of the first positioning hole 201 on the plane where the support plate 10 is located at least partially overlap. It can also be understood that each second positioning hole 301 is arranged below one first positioning hole 201, and the second positioning hole 301 and the first positioning hole 201 are in communication.

[0044] Specifically, the number of second positioning holes 301 can be the same as the number of first positioning holes 201, and the second positioning holes 301 and the first positioning holes 201 correspond one by one. Alternatively, the number of second positioning holes 301 can be less than the number of first positioning holes 201.

[0045] Figure 3 、 Figure 4 and Figure 5 The first positioning hole and the second positioning hole provided by the embodiment of the present application have several combination forms, as shown in Figure 3 In one embodiment, the orthographic projection of the second positioning hole 301 on the plane where the support plate 10 is located is completely located within the orthographic projection of the first positioning hole 201 on the plane where the support plate 10 is located. At this time, the cross-sectional area of the second positioning hole 301 is smaller than the cross-sectional area of the first positioning hole 201. As shown in Figure 4 In another embodiment, the orthographic projection of the first positioning hole 201 on the plane where the support plate 10 is located and the orthographic projection of the second positioning hole 301 on the plane where the support plate 10 is located have an overlapping area. The overlapping area is the area common to the orthographic projection of the first positioning hole 201 on the plane where the support plate 10 is located and the orthographic projection of the second positioning hole 301 on the plane where the support plate 10 is located. In addition to the overlapping area, the orthographic projection of the first positioning hole 201 on the plane where the support plate 10 is located and the orthographic projection of the second positioning hole 301 on the plane where the support plate 10 is located also have a part of the area that does not overlap, respectively. As shown in Figure 5As shown, in another embodiment, the orthographic projection of the first positioning hole 201 onto the plane of the base plate 10 and the orthographic projection of the second positioning hole 301 onto the plane of the base plate 10 completely overlap. In this case, the first positioning hole 201 and the second positioning hole 301 have the same shape and the same cross-sectional area.

[0046] Since the first positioning plate 20 and the second positioning plate 30 are detachably connected, the battery tray in this application includes two usage states depending on whether the first positioning plate 20 and the second positioning plate 30 are assembled. For ease of description, the two usage states are distinguished as the first usage state and the second usage state. In the first usage state, the battery tray includes a base plate 10 and the first positioning plate 20, and the second positioning plate 30 and the first positioning plate 20 are not assembled. The first positioning plate 20 has a plurality of first positioning holes 201, and the battery is placed in the first positioning holes 201. In the second usage state, in addition to the base plate 10 and the first positioning plate 20, the battery tray also includes a second positioning plate 30, which is installed on the side of the first positioning plate 20 facing away from the base plate 10. The first positioning plate 20 has a plurality of first positioning holes 201, and the second positioning plate 30 has a plurality of second positioning holes 301, and the battery is inserted into the first positioning holes 201 through the second positioning holes 301. On the battery production line, the battery tray can be switched between the two usage states by installing the second positioning plate 30 onto the first positioning plate 20, or by removing the second positioning plate 30 from the surface of the first positioning plate 20.

[0047] In both of the above-described usage states, the battery tray can be used to carry different batteries, and this "difference" can be reflected in aspects such as the cross-sectional area or height of the battery. The differences between the batteries are closely related to the structure of the first positioning plate 20 and the second positioning plate 30. For ease of description, the battery carried by the battery tray in the first usage state is referred to as the first battery, and the battery carried by the battery tray in the second usage state is referred to as the second battery. Several specific embodiments are described below.

[0048] like Figure 3 As shown, in one embodiment, the cross-sectional area of ​​the first positioning hole 201 is larger than the cross-sectional area of ​​the second positioning hole 301, and the orthographic projection of the second positioning hole 301 onto the plane of the base plate 10 is completely within the orthographic projection of the first positioning hole 201 onto the plane of the base plate 10. When the battery tray is in a first usage state, the first battery is directly inserted into the first positioning hole 201. When the battery tray is in a second usage state, the second battery passes through the second positioning hole 301 and is then inserted into the first positioning hole 201.

[0049] Since the cross-sectional area of the first positioning hole 201 is larger than the cross-sectional area of the second positioning hole 301, the cross-sectional area of the first battery can be larger than the cross-sectional area of the second battery. That is, when the battery tray is in the first use state, the battery tray can be used to carry a kind of battery with relatively large cross-sectional area. When the battery tray is in the second use state, the battery tray can be used to carry a kind of battery with relatively small cross-sectional area.

[0050] As shown in FIG. 1, in one embodiment, the first positioning hole 201 and the second positioning hole 301 are arranged in the bottom supporting plate 10 in a staggered manner. That is, the first positioning hole 201 and the second positioning hole 301 are arranged in the bottom supporting plate 10 in a staggered manner. Figure 4 As shown in FIG. 2, in another embodiment, the first positioning hole 201 and the second positioning hole 301 are arranged in the bottom supporting plate 10 in a staggered manner. That is, the first positioning hole 201 and the second positioning hole 301 are arranged in the bottom supporting plate 10 in a staggered manner.

[0051] When the battery tray is in the first use state, the first battery is directly inserted into the first positioning hole 201. When the battery tray is in the second use state, the second battery is inserted into the first positioning hole 201 after passing through the second positioning hole 301, and the second battery is accommodated in the space corresponding to the above-mentioned overlapping area. Since the cross-sectional area of the first positioning hole 201 is larger than the area of the above-mentioned overlapping area, the cross-sectional area of the first battery can be larger than the cross-sectional area of the second battery. That is, the battery tray in the above-mentioned embodiment can also be used to carry two kinds of batteries with different cross-sectional areas.

[0052] As shown in FIG. 3, in another embodiment, the first positioning hole 201 and the second positioning hole 301 are arranged in the bottom supporting plate 10 in a staggered manner. That is, the first positioning hole 201 and the second positioning hole 301 are arranged in the bottom supporting plate 10 in a staggered manner. Figure 5 As shown in FIG. 4, in another embodiment, the first positioning hole 201 and the second positioning hole 301 are arranged in the bottom supporting plate 10 in a staggered manner. That is, the first positioning hole 201 and the second positioning hole 301 are arranged in the bottom supporting plate 10 in a staggered manner.

[0053] In the second use state, the first positioning plate 20 and the second positioning plate 30 are stacked to increase the thickness of the battery tray, thereby providing a larger accommodation space for the second battery in the thickness direction of the battery tray, so that the length of the part of the second battery inserted into the battery tray increases, thereby improving the fixing effect of the second battery. Therefore, when the battery tray is in the second use state, the battery tray can be used to carry a kind of battery with relatively large height to improve the fixing effect of the battery. When the battery tray is in the first use state, the battery tray can be used to carry a kind of battery with relatively small height.

[0054] In the specific setting of the second positioning plate 30, the second positioning plate 30 includes various structural forms. Figure 6 A structural schematic diagram of the second positioning plate provided for the embodiments of the present application, Figure 7 An assembly schematic diagram of the second positioning plate and the first positioning plate provided for the embodiments of the present application. Refer to Figure 6 and Figure 7 In some embodiments, the second positioning plate 30 has a boss 302 on the side surface facing the first positioning plate 20. When the battery is in the second use state, the boss 302 is inserted into the first positioning hole 201. The boss 302 plays a positioning role, which can reduce the dislocation between the second positioning plate 30 and the first positioning plate 20, so that the connection between the second positioning plate 30 and the first positioning plate 20 is more compact.

[0055] As for the boss 302 and the second positioning hole 301, the number of the boss 302 can be equal to the number of the second positioning hole 301, and the two are one-to-one corresponding, and the second positioning hole 301 penetrates the boss 302. That is, one end of the second positioning hole 301 is located on the surface of the boss 302 facing the first positioning plate 20, and the other end of the second positioning hole 301 is located on the side surface of the second positioning plate 30 away from the boss 302.

[0056] In addition to setting the boss 302 and the second positioning hole 301 one-to-one, the number of the boss 302 can be more than the number of the second positioning hole 301, or less than the number of the second positioning hole 301. In another aspect, when the second positioning hole 301 is set on the second positioning plate 30 with the boss 302, the second positioning hole 301 can be set at a position corresponding to the boss 302, and the second positioning hole 301 penetrates the boss 302. Alternatively, the second positioning hole 301 can also be set at a position other than the boss 302.

[0057] As for the boss 302 and the first positioning hole 201, the number of the boss 302 can be equal to the number of the first positioning hole 201, and the two are one-to-one corresponding. Alternatively, the number of the boss 302 can be less than the number of the first positioning hole 201, but each boss 302 can be inserted into one first positioning hole 201.

[0058] In the above embodiments, since the second positioning hole 301 can penetrate the boss 302, and the boss 302 can be inserted into the first positioning hole 201, the cross-sectional area of the second positioning hole 301 is smaller than the cross-sectional area of the first positioning hole 201, and the orthographic projection of the second positioning hole 301 on the plane of the supporting plate 10 is completely located in the orthographic projection of the first positioning hole 201 on the plane of the supporting plate 10. According to the above analysis, the battery tray in the above embodiments can be used to carry two kinds of batteries with different cross-sectional areas.

[0059] Figure 8 A structure diagram of a first positioning plate provided in an embodiment of the present application is shown in FIG. 1, and reference is made to FIG. 1 Figure 6 and Figure 8 In some embodiments, the peripheral surface of the boss 302 has a protrusion 3021 extending along the thickness direction of the second positioning plate 30. Correspondingly, the inner wall of the first positioning hole 201 has a limiting groove 2011 extending along the thickness direction of the first positioning plate 20. During the process of inserting the boss 302 into the first positioning hole 201, the protrusion 3021 is also inserted into the limiting groove 2011. After the boss 302 is inserted into position, the protrusion 3021 is accommodated in the limiting groove 2011. The cooperation of the protrusion 3021 and the limiting groove 2011 further reduces the dislocation between the second positioning plate 30 and the first positioning plate 20, so that the first positioning plate 20 and the second positioning plate 30 are more firmly assembled.

[0060] In the specific arrangement of the protrusion 3021, the number of the protrusions 3021 is not limited. For example, the protrusion 3021 can be one or multiple. In the embodiment in which the peripheral surface of the boss 302 has multiple protrusions 3021, the multiple protrusions 3021 are uniformly distributed along the circumferential direction.

[0061] Figure 9 Another assembly diagram of the second positioning plate and the first positioning plate provided in an embodiment of the present application is shown in FIG. 2, and reference is made to FIG. 2 Figure 9 In an embodiment, the side surface of the second positioning plate 30 facing the first positioning plate 20 can also be a plane. and Figure 7 Compared with the second positioning plate 30 shown in FIG. 1, the side surface of the second positioning plate 30 in this embodiment facing the first positioning plate 20 is relatively flat and does not have a boss 302. In this embodiment, the second positioning hole 301 and the first positioning hole 201 can adopt any combination of the combinations shown in FIG. 3 Figure 3 , Figure 4 and Figure 5

[0062] In a specific embodiment, the first positioning plate 20 and the second positioning plate 30 have multiple connection positions. When the first positioning plate 20 and the second positioning plate 30 are switched between the multiple connection positions, the first positioning plate 20 and the second positioning plate 30 are relatively dislocated, and the area of the overlapping region formed by the orthographic projection of the first positioning hole 201 on the plane where the bottom plate 10 is located and the orthographic projection of the second positioning hole 301 on the plane where the bottom plate 10 is located is changed, so that the battery tray in the second use state can accommodate different models of batteries.

[0063] In the specific connection of the first positioning plate 20 and the second positioning plate 30, in order to realize the quick disassembly and assembly of the first positioning plate 20 and the second positioning plate 30, as shown in FIG. 4 Figure 6 and Figure 8 ​As shown, in some embodiments, one of the first positioning plate 20 and the second positioning plate 30 is provided with a buckle 40, and the other is provided with a clamping groove 50. When the second positioning plate 30 needs to be installed on the surface of the first positioning plate 20, the second positioning plate 30 can be pressed to make the buckle 40 clamped into the clamping groove 50. During the process of entering the clamping groove 50, the buckle 40 can be extruded and deformed. After the buckle 40 enters the clamping groove 50, the buckle 40 and the inner wall of the clamping groove 50 are in close contact, so as to realize clamping, so that the first positioning plate 20 and the second positioning plate 30 are quickly connected. When the second positioning plate 30 needs to be removed from the surface of the first positioning plate 20, a pulling force can be applied to the second positioning plate 30, so that the buckle 40 is separated from the clamping groove 50, thereby realizing the quick separation of the second positioning plate 30 and the first positioning plate 20.

[0064] When the buckle 40 and the clamping groove 50 are specifically arranged, the buckle 40 and the clamping groove 50 are distributed on the two opposite surfaces of the first positioning plate 20 and the second positioning plate 30. The buckle 40 and the clamping groove 50 can be a pair or multiple pairs. For any pair of buckle 40 and clamping groove 50, the buckle 40 and the clamping groove 50 can be distributed near the edge of the corresponding surface, or can be distributed near the center of the corresponding surface.

[0065] Figure 10 Another assembly schematic diagram of the first positioning plate and the second positioning plate provided by the embodiments of the present application is shown in FIG. 6. Figure 10 As shown, in an embodiment, the circumferential edge of the first positioning plate 20 has a first notch 202, and the first notch 202 penetrates the first positioning plate 20 along the thickness direction of the first positioning plate 20. The circumferential edge of the second positioning plate 30 has a second notch 303, and the second notch 303 penetrates the second positioning plate 30 along the thickness direction of the second positioning plate 30. The first notch 202 and the second notch 303 are arranged on the same side, the first notch 202 has an overlapping area with the second notch 303 in the orthogonal projection of the bottom support plate 10, and the area of the overlapping area is smaller than the area of the orthogonal projection of the first notch 202 in the bottom support plate 10.

[0066] Figure 11 A position schematic diagram of the orthogonal projection of the first notch in the bottom support plate and the orthogonal projection of the second notch in the bottom support plate provided by the embodiments of the present application is shown in FIG. 7. Figure 11 As shown, the above-mentioned overlapping area A is located in the orthogonal projection of the first notch 202 in the bottom support plate 10. In addition to the above-mentioned overlapping area A, the orthogonal projection of the first notch 202 in the bottom support plate 10 also includes a first area B which is not covered by the orthogonal projection of the second notch 303 in the bottom support plate 10. It can also be understood that the space corresponding to the first area B is located below the solid structure of the second positioning plate 30 and is covered by the solid structure of the second positioning plate 30.

[0067] When it is necessary to separate the second positioning plate 30 from the surface of the first positioning plate 20, the fingers or the operating tool of the worker can be inserted into the space corresponding to the first region B of the first gap 202 through the second gap 303, and the fingers or the operating tool of the worker can hold the second positioning plate 30 and pull the second positioning plate 30 upward, so that the second positioning plate 30 is separated from the first positioning plate 20.

[0068] In an embodiment, the peripheral side edge of the second positioning plate 30 has a plurality of second gaps 303, and at least part of the second gaps 303 are located on opposite sides of the second positioning plate 30. In addition, the first positioning plate 20 has a first gap 202 at a position corresponding to each second gap 303. When it is necessary to separate the second positioning plate 30 from the surface of the first positioning plate 20, the fingers or the operating tool can be inserted into the corresponding first gap 202 through the two oppositely arranged second gaps 303, so that the second positioning plate 30 is pulled upward from the opposite sides at the same time, so that the second positioning plate 30 is uniformly stressed and is more easily separated from the first positioning plate 20.

[0069] In the specific arrangement of the first gap 202 and the second gap 303, as shown in Figure 11 In an embodiment, the first gap 202 and the second gap 303 are rectangular gaps. The first gap 202 is located on the first side wall of the first positioning plate 20, and the first side wall extends along the first direction X in the orthogonal projection on the plane of the base plate 10. If the second direction Y represents another direction perpendicular to the first direction X and parallel to the plane of the base plate 10, then the size of the first gap 202 along the first direction X is greater than the size of the first gap 202 along the second direction Y. Compared with the above-mentioned first gap 202, the size of the second gap 303 along the first direction X is greater than or equal to the size of the first gap 202 along the first direction X, and the size of the second gap 303 along the second direction Y is less than the size of the first gap 202 along the second direction Y.

[0070] In the case of a certain size of the first gap 202, by making the size of the second gap 303 along the first direction X greater than or equal to the size of the first gap 202 along the first direction X, the opening area of the second gap 303 can be increased, so that the fingers or the operating tool can be inserted into the first gap 202 through the second gap 303.

[0071] Of course, in addition to being rectangular gaps, the first gap 202 and the second gap 303 can also be semicircular gaps or other shaped gaps, which are not listed one by one in the present application.

[0072] Figure 12 An assembly diagram of the first positioning plate and the base plate provided in an embodiment of the present application is shown inFigure 12 As shown, in an embodiment, a fastener 60 is arranged between the first positioning plate 20 and the bottom supporting plate 10, and the fastener 60 penetrates through the first positioning plate 20 and is connected with the bottom supporting plate 10. The fastener 60 can enhance the connecting effect of the first positioning plate 20 and the bottom supporting plate 10, so that the first positioning plate 20 and the bottom supporting plate 10 are more firm after being assembled. In the case that the first positioning plate 20 and the second positioning plate 30 are clamped, the fastener 60 can make the first positioning plate 20 and the bottom supporting plate 10 not easy to be loosened in the process of separating the second positioning plate 30 from the first positioning plate 20 by pulling the second positioning plate 30. Optionally, the fastener 60 includes a screw or a bolt.

[0073] In the specific installation of the fastener 60, the side surface of the first positioning plate 20 facing the second positioning plate 30 has a receiving groove 203, and the end of the fastener 60 is located in the receiving groove 203 and does not protrude from the surface of the first positioning plate 20. When the battery tray is in the first use state, since the end of the fastener 60 is completely accommodated in the receiving groove 203 on the surface of the first positioning plate 20, the risk of electrical connection between the fastener 60 and the battery is reduced. Based on the same consideration, the end of the fastener 60 can also be sleeved with an insulating cap 70, and the insulating cap 70 is completely located in the above-mentioned receiving groove 203, so as to further reduce the risk of electrical connection between the fastener 60 and the battery.

[0074] In the specific installation of the fastener 60, in an embodiment, the fastener 60 includes a nut and a screw rod, the nut is completely located in the receiving groove 203, and a gasket 80 is arranged between the nut and the bottom wall of the receiving groove 203. The gasket 80 can make the stress of the first positioning plate 20 more uniform, so as to reduce the risk of damage of the first positioning plate 20 under pressure.

[0075] In the specific installation of the bottom supporting plate 10, the bottom supporting plate 10 includes various structural forms. Figure 13 A structural schematic diagram of the bottom supporting plate 10 provided in an embodiment of the present application is shown in Figure 13 As shown, in an embodiment, the bottom supporting plate 10 has a hollow part 101 and a solid part 102. The shape of the hollow part 101 is not limited, for example, the hollow part 101 can be circular, oval or irregular. The number of the hollow part 101 is not limited, and the hollow part 101 can be arranged randomly or according to a set rule. According to the different shapes, the bottom supporting plate 10 can have one kind of hollow part 101 or multiple kinds of hollow part 101. The hollow part 101 can reduce the weight of the bottom supporting plate 10, so that the battery tray is light and easy to carry.

[0076] In order to enable the base plate 10 to support the battery, at least a portion of the orthographic projection of each first positioning hole 201 on the surface of the base plate 10 is located on the surface of the solid portion 102, so that when the battery is inserted into the first positioning hole 201, the end of the battery can be supported on the surface of the solid portion 102.

[0077] In another embodiment, the base plate 10 may not have the aforementioned hollow portion.

[0078] The base plate 10 and the first positioning plate 20 can be separate structures, which can be connected by fasteners 60. Alternatively, the base plate 10 and the first positioning plate 20 can be an integral structure. Optionally, the base plate 10 and the first positioning plate 20 can be integrally formed by injection molding.

[0079] Figure 14 This is another structural schematic diagram of the battery tray provided in the embodiments of this application, as shown below. Figure 14 As shown, in one embodiment, a frame 90 is provided around the base plate 10, and a first positioning plate 20 and a second positioning plate 30 are located within the frame 90. The frame 90 can form a barrier around the first positioning plate 20 and the second positioning plate 30, thereby reducing the risk of the battery falling. Specifically, when the frame 90 is set, gripping parts 901 are provided on opposite sides of the frame 90. The gripping parts 901 make it easier for workers to apply force to the battery tray, thereby facilitating the handling of the battery tray.

[0080] The frame 90 and the base plate 10 can be connected by fasteners, or the frame 90 and the base plate 10 can be an integral structure.

[0081] The frame 90 is an insulating component and can be manufactured using injection molding. The base plate 10, the first positioning plate 20, and the second positioning plate 30 can also be insulating components and can be manufactured using injection molding.
