[0044] Please refer to Figures 1 - 3 , wherein, Figure 1 FIG. shows a schematic structural diagram of a battery tray 100 with a connector 30 provided in an embodiment of the present application; Figure 2 FIG. shows a partially enlarged schematic diagram of the battery tray 100 with a connector 30 provided in an embodiment of the present application; Figure 3 FIG. shows a partial cross-sectional schematic diagram of the battery tray 100 provided in an embodiment of the present application.

[0045] The battery tray 100 of the present application includes a first side beam 20 for enclosing a battery accommodation cavity 11, and the first side beam 20 is provided with a mounting hole 23 for mounting the connector 30.

[0046] Specifically, in one embodiment, as Figures 1 - 3 shown, the plate surface of the bottom plate 10 and the first side beam 20 enclose to form the battery accommodation cavity 11, the first side beam 20 is used to form part of the side wall of the battery accommodation cavity 11, the connector 30 is disposed in the mounting hole 23, one end of the connector 30 is located on the side of the first side beam 20 facing the battery accommodation cavity 11 for electrically connecting with the battery, and the other end passes through and extends out of the first side beam 20. The part of the connector 30 extending out of the first side beam 20 is used to electrically connect with an external electrical device, so that the battery is electrically connected to the electrical device to realize the power supply of the electrical device.

[0047] The battery tray 100 of the present application includes a first protective member 40, the first protective member 40 is connected to the side of the first side beam 20 away from the battery accommodation cavity 11 and is disposed around the periphery of the mounting hole 23, and the first protective member 40 extends in a direction away from the battery accommodation cavity 11.

[0048] Specifically, in one embodiment, as Figures 1 - 3As shown, the first protective member 40 is disposed around the periphery of the mounting hole 23, and the first protective member 40 is spaced apart from the mounting hole 23. The connector 30 is disposed in the mounting hole 23, and the length of the first protective member 40 is greater than the length of the connector 30 protruding from the first side beam 20. Along a direction perpendicular to the extending direction of the connector 30, the first protective member 40 shields the end of the connector 30 protruding from the first side beam 20, so that external dust, gravel, and splashing water cannot contact the connector 30 from the side of the connector 30, thereby protecting the connector 30.

[0049] In the battery tray 100 of the present application, the battery accommodation cavity 11 is surrounded by the first side beam 20, and the connector 30 is disposed in the mounting hole 23 of the first side beam 20 for conducting the internal battery and the external electrical device, thereby realizing the power supply of the electrical device.

[0050] The battery tray 100 of the present application can be applied to a battery device. The battery device includes a battery, a connector 30, and a battery tray 100. The battery is disposed in the battery accommodation cavity 11 of the battery tray 100, and one end of the battery is electrically connected to the connector 30 of the battery tray 100. The external electrical device can be electrically connected to the other end of the connector 30 to realize the power supply of the electrical device.

[0051] The battery tray 100 of the present application can also be applied to an electrical device. The electrical device includes an electrical device and a battery device. The electrical device is electrically connected to the battery in the battery device through the connector of the battery device, and the power supply of the electrical device can also be realized.

[0052] During the transportation of the battery device or in the scenario where the battery is installed on a vehicle, the dust and gravel on the ground may be lifted and move towards the battery from the ground, thereby damaging the exposed connector 30 of the battery device.

[0053] Similarly, in rainy days or when there is accumulated water on the ground, the rainwater or splashed accumulated water may directly contact the exposed connector 30, thereby corroding the connector 30.

[0054] In addition, for the scenario where the battery device is installed on a vehicle or the electrical device is a vehicle, during the vehicle washing process, the relatively fast flowing water will impact the vehicle. When the flowing water directly impacts the exposed connector 30, the connector 30 is more likely to be damaged.

[0055] The battery tray 100 of the present application is provided with a first protective member 40 surrounding the periphery of the mounting hole 23. The first protective member 40 can protect the connector 30 disposed in the mounting hole 23. External dust, gravel, and splashing liquid will first contact the first protective member 40, preventing external dust and splashing liquid from contacting the connector 30, thereby improving the reliability of the battery tray 100 and extending its service life.

[0056] It can be understood that the first protective member 40 of the battery tray 100 of the present application can not only protect the connector 30 on the first side beam 20, but also protect the electrical connection member of the external electrical device for connecting the connector 30. The first protective member 40 can continue to extend to shield the electrical connection member of the electrical device, thereby improving the reliability of the electrical connection between the battery and the electrical device.

[0057] It should be noted that the battery tray 100 of the present application can be applied not only to the above-mentioned battery device and electrical equipment, but also to devices or systems with exposed electrical connection members. The battery tray 100 of the present application is equally applicable, and can prevent external substances from directly contacting the electrical connection members, protect the electrical connection members, thereby improving the reliability of the device or system and extending its service life.

[0060] In one embodiment, as Figure 4 shown, the first side beam 20 of the battery tray 100 is provided with two spaced-apart mounting holes 23. Two first protective members 40 are respectively disposed outside one mounting hole 23, and the two first protective members 40 are spaced apart from each other. A first reinforcing rib 51 is provided between the two first protective members 40. The two ends of the first reinforcing rib 51 are respectively connected to the two first protective members 40 to improve the overall strength of the first protective member 40 to ensure the protection effect of the connector 30.

[0061] In another embodiment, the first side beam 20 of the battery tray 100 can be provided with more connectors 30. One first protective member 40 can be disposed outside a plurality of mounting holes 23, and can also protect the connectors 30.

[0062] In one embodiment, one first protective member 40 is disposed around at least one first protective member 40, and a second reinforcing rib is provided between the relatively outer first protective member 40 and the relatively inner first protective member 40. One first protective member 40 is disposed around another first protective member 40. The protection of multiple layers of first protective members 40 can ensure the protection effect of the connector 30.

[0063] In one embodiment, a first protective member 40 is disposed around the periphery of a plurality of first protective members 40. The plurality of first protective members 40 on the relatively inner side are connected by a first reinforcing rib 51, and each of the first protective members 40 on the relatively inner side and the first protective member 40 on the relatively outer side are connected by a second reinforcing rib, so as to improve the overall strength of the first protective member 40, thereby ensuring the protection effect of the connector 30.

[0064] In one embodiment, along the direction away from the battery accommodation cavity 11, the length of the first protective member 40 is greater than the length of the connector 30 protruding from the first side beam 20.

[0065] In one embodiment, the distance range between the end of the first protective member 40 away from the battery accommodation cavity 11 and the end of the connector 30 away from the battery accommodation cavity 11 is 15 mm - 25 mm.

[0066] In one embodiment, along the direction perpendicular to the extension direction of the first protective member 40, the distance range between the first protective member 40 and the mounting hole 23 is 10 mm - 50 mm.

[0067] Please refer to Figures 5 - 8 , wherein, Figure 5 shows a schematic structural diagram of another perspective of the battery tray 100 with the connector 30 provided in an embodiment of the present application; Figure 6 shows a schematic cross-sectional view of the battery tray 100 with the connector 30 provided in an embodiment of the present application;

[0068] Figure 7 shows a partially enlarged schematic diagram of a cross-section on one side of the battery tray 100 with the connector 30 provided in an embodiment of the present application; Figure 8 shows a partially enlarged schematic diagram of a cross-section on the other side of the battery tray 100 with the connector 30 provided in an embodiment of the present application.

[0069] In one embodiment, the battery tray 100 includes a connecting member 21. A part of the connecting member 21 is connected to the first side beam 20 and extends in the direction close to the battery accommodation cavity 11. The connecting member 21 is located outside the first protective member 40, and the connecting member 21 is used to connect the bottom plate 10 and / or the electrical device.

[0070] In one embodiment, a third reinforcing rib 52 is provided between the connecting member 21 and the first protective member 40. The connecting member 21 and the first protective member 40 are connected by the third reinforcing rib 52 to improve the overall strength of the first protective member 40, thereby ensuring the protection effect of the connector 30.

[0071] In one embodiment, as Figures 5 - 8As shown, the connecting member 21 is fixed to the first side beam 20 and extends towards the bottom plate 10, so that the connecting member 21 is fixed to the bottom plate 10 to achieve a fixed connection between the first side beam 20 and the bottom plate 10.

[0072] In another embodiment, the connecting member 21 is fixed to the first side beam 20 and extends away from the battery accommodation cavity 11 for fixing an external electrical device.

[0073] In another embodiment, the connecting member 21 includes a side connecting member 22. The side connecting member 22 is located on the side of the first side beam 20 away from the battery accommodation cavity and outside the first protective member 40. Along the direction away from the battery accommodation cavity 11, the length of the side connecting member 22 is greater than the length of the first protective member 40, and the side connecting member 22 is used to fix the electrical device.

[0074] In one embodiment, as Figure 5 shown, the side connecting member 22 extends away from the battery accommodation cavity 11, and each side connecting member 22 is provided with a connection hole for connecting an external electrical device. Please refer to Figure 2 shown, a third reinforcing rib 52 is provided between the side connecting member 22 and the first protective member 40. The third reinforcing rib 52 is used to improve the overall strength of the first protective member 40, thereby ensuring the protection effect of the connector 30.

[0075] It can be understood that along the direction perpendicular to the extension direction of the connector 30, the side connecting member 22 also shields part of the first protective member 40 and can also protect the first protective member 40.

[0076] In one embodiment, the first protective member 40, the connecting member 21, and the first side beam 20 are integrally formed to improve the connection strength between the first protective member 40 and the first side beam 20 and the connection strength between the connecting member 21 and the first side beam 20, thereby ensuring the protection effect of the connector 30.

[0077] In one embodiment, as Figure 5 shown, the first protective member 40, the connecting member 21 for fixing the bottom plate 10, the side connecting member 22 for fixing an external electrical device, and the first side beam 20 are integrally formed to improve the connection strength between the first protective member 40 and the first side beam 20, the connection strength between the connecting member 21 and the first side beam 20, and the connection strength between the side connecting member 22 and the first side beam 20, thereby ensuring the protection effect of the connector 30.

[0078] In one embodiment, the battery tray 100 includes a bottom plate 10 and a plurality of second side beams 24. The first side beam 20 and the plurality of second side beams 24 are sequentially connected to form a frame, and the bottom plate 10 is connected to the frame to enclose the battery accommodation cavity 11.

[0079] In one embodiment, asFigures 6 - 8 As shown in the figure, the battery tray 100 includes a first side beam 20 and a second side beam 24 located on opposite sides. The first side beam 20 and the second side beam 24 enclose a frame, and the frame is connected to the bottom plate 10 to form a battery accommodation cavity 11. The battery is disposed between the first side beam 20 and the second side beam 24, and the first side beam 20 and the second side beam 24 at least partially shield the battery to protect the battery.

[0080] In one embodiment, along the direction away from the battery accommodation cavity 11, the distance range between the end of the side connection member 22 away from the battery accommodation cavity 11 and the end of the first protective member 40 away from the battery accommodation cavity 11 is 30 mm - 50 mm.

[0081] In one embodiment, along the direction of the battery accommodation cavity 11 towards the bottom plate 10, the side connection member 22 is located on one side of the first protective member 40.

[0082] In one embodiment, along the arrangement direction of the battery accommodation cavity and the bottom plate 10, the distance range between the side connection member 22 and the first protective member 40 is 2 mm - 10 mm.

[0083] In one embodiment, as Figure 6 shown, a partition is fixed in the middle of the bottom plate 10. The partition is parallel to the first side beam 20 and the second side beam 24, and is used to divide the area in the battery tray 100 for accommodating the battery.

[0084] Please refer to Figure 9 and Figure 10 , wherein, Figure 9 shows another cross-sectional view of the battery tray with the connector 30 provided in an embodiment of the present application; Figure 10 shows a partial enlarged view of another cross-section of the battery tray with the connector 30 provided in an embodiment of the present application.

[0085] In one embodiment, the battery tray 100 includes a second protective member 41. The second protective member 41 is connected to the side of the first side beam 20 away from the battery accommodation cavity 11 and is disposed around the periphery of the mounting hole 23. The second protective member 41 extends towards the battery accommodation cavity.

[0086] In one embodiment, as Figure 9 and Figure 10 shown, the other end of the connector 30 extends towards the battery accommodation cavity 11 and protrudes from the first side beam 20. The second protective member 41 is disposed around the periphery of the other end of the connector 30, and shields a part of the other end of the connector 30 protruding from the first side beam 20, for protecting the other end of the connector 30.

[0087] It is understandable that when the battery is electrically connected to the connector 30, the second protective member 41 restricts the displacement between the battery and the connector 30 to prevent relative movement of the battery from damaging the connector 30. In one embodiment, as Figure 10 shown, the connector 30 includes a through section 31 that is embedded in the first side beam 20 and is located between the two ends of the connector 30. The size of the through section 31 is smaller than the sizes of the two ends of the connector 30 to restrict the displacement of the connector 30 relative to the first side beam 20, thereby ensuring the connection between the connector 30 and the first side beam 20.

[0088] In another embodiment, the sizes of the two ends of the connector 30 are different. The end with the larger size of the connector 30 is fixed to the first side beam 20 by a fastener, which can also restrict the displacement of the connector 30 relative to the first side beam 20, thereby ensuring the connection between the connector 30 and the first side beam 20.

[0089] In one embodiment, as Figure 10 shown, the size of the end of the connector 30 facing the battery accommodation cavity 11 is larger than the size of the end away from the battery accommodation cavity 11. The end of the connector 30 facing the battery accommodation cavity 11 is fixed to the first side beam 20 by a fastener to ensure the connection between the connector 30 and the first side beam 20.

[0090] Please refer to Figures 11 - 15 , in which Figure 11 shows a schematic structural diagram of another perspective of the battery tray 100 provided in an embodiment of the present application; Figure 12 shows an exploded schematic diagram of the protective plate 60 provided in an embodiment of the present application; Figure 13 shows a schematic cross-sectional diagram of the protective plate 60 provided in an embodiment of the present application; Figure 14 shows a partially enlarged schematic diagram of the cross-section of the protective plate 60 provided in an embodiment of the present application; Figure 15 shows a schematic structural diagram of the protective plate 60 provided in an embodiment of the present application.

[0091] In one embodiment, the battery tray 100 includes a protective plate 60. The protective plate 60 is connected to the side of the frame away from the battery accommodation cavity 11 and is located on the side of the bottom plate 10 away from the battery accommodation cavity 11.

[0092] In one embodiment, as Figure 11 shown, the battery tray 100 includes a protective plate 60. The protective plate 60 is fixed to the side of the bottom plate 10 away from the battery accommodation cavity 11. The protective plate 60 is used to protect the bottom plate 10 of the battery tray 100 to prevent the bottom plate 10 from being damaged and thus exposing the battery in the battery tray 100.

[0093] In one embodiment, the strength of the protective plate 60 is greater than that of the bottom plate 10 to protect the bottom plate.

[0094] In one embodiment, please refer to Figure 7 and Figure 11 As shown, the protective plate 60 extends to the side of the first side beam 20 away from the battery accommodation cavity 11. Along the direction away from the battery accommodation cavity 11, the protective plate 60 shields at least part of the first protective member 40. The protective plate 60 extends to the side of the first side beam 20 away from the battery accommodation cavity 11 so that the protective plate 60 can also protect the first protective member 40, thereby ensuring the protection effect of the connector 30.

[0095] In one embodiment, as Figure 12 shown, the protective plate 60 is composed of a first protective layer 61, a honeycomb panel 62, a metal plate 63, and a second protective layer 64 arranged in sequence. The first protective layer 61 and the second protective layer 64 act together to form a protective layer to separate the honeycomb panel 62 and the metal plate 63 from the outside.

[0096] It can be understood that after separating from the outside, the rusting process of the metal plate 63 can be slowed down, and the service life of the protective plate 60 can be extended.

[0097] In one embodiment, the material of the first protective layer 61 and / or the second protective layer 64 includes fiberglass to improve the overall strength of the protective plate 60.

[0098] In one embodiment, as Figures 13 - 15 shown, the two sides of the protective plate 60 are respectively provided with a first boss 601 and a second boss 602. Please refer to Figure 7 and Figure 8 , the connecting members 21 on both sides and the bottom plate 10 form a mating groove for accommodating the first boss 601. At least part of the first boss 601 is located in the mating groove, restricting the relative displacement between the bottom plate 10 and the protective plate 60 and ensuring that the protective plate 60 can shield the bottom plate 10. At the same time, the connection between the first boss 601 and the mating groove can also improve the connection strength between the protective plate 60 and the connecting member 21.

[0099] In one embodiment, along the direction away from the first side beam 20, the distance between the side of the first protective member 40 facing the bottom plate 10 and the connector 30 increases, causing the first protective member 40 to tilt in the direction away from the connector 30, and relying on gravity to discharge the dust, gravel or liquid deposited between the connector 30 and the first protective member.
