[0002] This application relates to the field of battery technology, and more specifically, to a battery tray, a battery device, and an electrical appliance. Background Technology

[0003] The battery unit has exposed connectors for connecting to external electrical devices.

[0004] During battery transport or while traveling with a vehicle, the connectors are easily damaged by external sand, gravel, and splashing liquids. Summary of the Invention

[0005] The purpose of this application is to provide a battery tray, battery device, and electrical equipment to solve the technical problem that battery connectors are easily damaged in related technologies.

[0006] In a first aspect, embodiments of this application provide a battery tray, including a first side beam for forming a battery receiving cavity, the first side beam having a mounting hole for mounting a connector; a first protective member connected to the side of the first side beam away from the battery receiving cavity and surrounding the periphery of the mounting hole; the first protective member extending in a direction away from the battery receiving cavity.

[0007] In some embodiments, the battery tray includes a plurality of mounting holes and a plurality of first protective members, each first protective member being disposed around at least one mounting hole, and a first reinforcing rib being provided between two adjacent first protective members.

[0008] In this embodiment, the battery tray is provided with a plurality of first protective members for protecting the connectors disposed in the mounting holes. Adjacent first protective members are connected by first reinforcing ribs to improve the overall strength of the first protective members, thereby ensuring the protective effect of the connectors.

[0009] In some embodiments, a first protective member is disposed around the periphery of at least one first protective member, and a second reinforcing rib is provided between the relatively outer first protective member and the relatively inner first protective member.

[0010] In this embodiment, one first protective member is arranged around the periphery of another first protective member to ensure the protective effect of the connector. The relatively outer first protective member and the relatively inner first protective member are connected by a second reinforcing rib, which can improve the overall strength of the first protective member and thus ensure the protective effect of the connector.

[0011] In some embodiments, the battery tray further includes a connector, part of which is connected to the first side beam and extends toward the direction of the battery receiving cavity. The connector is located outside the first protective member and is used to connect the base plate and / or the electrical device.

[0012] In some embodiments, the connector includes a side connector located on the side of the first side beam away from the battery housing cavity and outside the first protective member. Along the direction away from the battery housing cavity, the length of the side connector is greater than the length of the first protective member. The side connector is used to fix the electrical device.

[0013] In this embodiment, the side connector is located outside the first protective member and its length is greater than that of the first protective member, so that the external electrical device can be fixed to the side connector and space is left for the electrical device to connect to the connector.

[0014] In some embodiments, the first protective member, the connector, and the first side beam are integrally formed.

[0015] In this embodiment, the first protective component, the connector, and the first side beam are integrally formed to improve the connection strength between the first protective component and the first side beam, as well as the connection strength between the connector and the first side beam, thereby ensuring the protective effect of the connector provided in the mounting hole.

[0016] In some embodiments, the battery tray includes a second protective member connected to the side of the first side beam away from the battery receiving cavity and surrounding the periphery of the mounting hole, the second protective member extending toward the battery receiving cavity.

[0017] In this embodiment, the second protective member is circumferentially disposed around the mounting hole and extends toward the battery receiving cavity to protect the connector disposed in the mounting hole. When the battery and the connector are connected, the second protective member restricts the displacement between the battery and the connector, preventing the battery from moving and damaging the connector.

[0018] In some embodiments, the battery tray further includes a chassis and a plurality of second side beams, the first side beams and the plurality of second side beams being connected in sequence to form a frame, and a base plate being connected to the frame to enclose the battery receiving cavity.

[0019] In some embodiments, the battery tray includes a protective plate attached to the side of the frame away from the battery housing cavity and located on the side of the base plate away from the battery housing cavity.

[0020] In some embodiments, the protective plate extends to the side of the first side beam away from the battery housing cavity, and in the direction away from the battery housing cavity, the protective plate at least partially shields the first protective member.

[0021] In this embodiment, the protective plate extends to the side of the first side beam away from the battery housing cavity, so that the protective plate can also protect the first protective component, thereby ensuring the protective effect of the connector set in the mounting hole.

[0022] Secondly, embodiments of this application also provide a battery device, including a battery, a connector and the aforementioned battery tray, wherein the battery is disposed inside the battery receiving cavity of the battery tray, the connector is installed in the mounting hole of the first side beam and protrudes from the first side beam, and the battery and the connector are electrically connected.

[0023] In some embodiments, the length of the first protective member is greater than the length of the connector protruding from the first side beam in the direction away from the battery housing cavity.

[0024] Thirdly, embodiments of this application also provide an electrical device, including an electrical device and the aforementioned battery device, wherein a connector of the battery device is electrically connected to the electrical device to supply power to the electrical device.

[0025] The battery tray of this application has a battery housing cavity for holding batteries, and a connector is provided in the mounting hole to connect the battery in the battery housing cavity to an external electrical device, thereby enabling power supply to the external electrical device.

[0026] The battery tray of this application has a first protective member surrounding the mounting hole. When the connector is installed in the mounting hole, the first protective member can protect the connector in the mounting hole and prevent external sand, gravel and splashing liquid from contacting the connector, thereby improving the reliability of the battery tray and extending its service life.

[0027] Understandably, the electrical equipment and battery device of this application, by adopting the aforementioned battery tray, can protect the connectors provided in the mounting holes, thereby improving the reliability of the electrical equipment and battery device and extending its service life.

[0047] Please refer to Figures 1-3, wherein Figure 1 illustrates a structural schematic diagram of a battery tray 100 with connector 30 provided in some embodiments of this application; Figure 2 illustrates a partially enlarged schematic diagram of a battery tray 100 with connector 30 provided in some embodiments of this application; and Figure 3 illustrates a partial cross-sectional schematic diagram of a battery tray 100 provided in some embodiments of this application.

[0048] The battery tray 100 of this application includes a first side beam 20 for forming a battery receiving cavity 11, and the first side beam 20 is provided with mounting holes 23 for mounting connectors 30.

[0049] Specifically, in some embodiments, as shown in Figures 1-3 and 17, the surface of the base plate 10 and the first side beam 20 together form a battery receiving cavity 11. The first side beam 20 is used to form part of the sidewall of the battery receiving 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 receiving cavity 11 and is used for electrical connection with the battery 200. 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 for electrical connection with the external power device 400, so that the battery 200 is connected to the power device 400 and the power device 400 is powered.

[0050] The battery tray 100 of this application includes a first protective member 40, which is connected to the side of the first side beam 20 away from the battery receiving cavity 11 and is disposed around the periphery of the mounting hole 23. The first protective member 40 extends in a direction away from the battery receiving cavity 11.

[0051] Specifically, in some embodiments, as shown in Figures 1-3 and 17, the first protective member 40 is arranged around the periphery of the mounting hole 23, and the first protective member 40 and the mounting hole 23 are spaced apart from each other. 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 extending out of the first side beam 20. Along the extension direction perpendicular to the connector 30, the first protective member 40 shields the end of the connector 30 extending out of the first side beam 20, so that external sand, gravel, and splashing water cannot come into contact with the connector 30 from the side, thereby protecting the connector 30.

[0052] Referring to Figure 16, the battery tray 100 of this application forms a battery receiving cavity 11 through the first side beam 20. The mounting hole 23 of the first side beam 20 is provided with a connector 30 for conducting the internal battery 200 and the external power device 400, thereby realizing the power supply of the power device 400.

[0053] The battery tray 100 of this application can be applied to a battery device 300, which includes a battery 200, a connector 30 and a battery tray 100. The battery 200 is disposed in the battery receiving cavity 11 of the battery tray 100. The battery 200 is electrically connected to one end of the connector 30 of the battery tray 100. An external power device 400 can be electrically connected to the other end of the connector 30 to provide power to the power device 400.

[0054] Referring to Figure 17, the battery tray 100 of this application can also be applied to the electrical device 500, which includes an electrical device 400 and a battery device 300. The electrical device 400 is connected to the battery 200 in the battery device 300 through the connector 30, and can also realize the power supply of the electrical device 400.

[0055] During the transportation of the battery device 300 or in a scenario where the battery is installed on a vehicle, dust and gravel on the ground may be stirred up and move from the ground toward the battery, thereby damaging the exposed connectors 30 of the battery device 300.

[0056] Similarly, in rainy weather or when there is standing water on the ground, rainwater or splashed water may come into direct contact with the exposed connector 30, thereby corroding the connector 30.

[0057] In addition, in scenarios where the battery device 300 is installed on a vehicle or the electrical equipment 500 is a vehicle, during the vehicle washing process, the high-speed water flow will impact the vehicle. When the water flow directly impacts the exposed connector 30, the connector 30 is more likely to be damaged.

[0058] The battery tray 100 of this application is provided with a first protective member 40 surrounding the mounting hole 23. The first protective member 40 can protect the connector 30 set in the mounting hole 23. External sand, gravel and splashing liquid will first come into contact with the first protective member 40, preventing external sand and splashing liquid from contacting the connector 30, thereby improving the reliability of the battery tray 100 and extending its service life.

[0059] Understandably, the first protective member 40 of the battery tray 100 of this application can not only protect the connector 30 on the first side beam 20, but also protect the electrical connector of the external electrical device 400 used to connect the connector 30. The first protective member 40 can continue to extend to shield the electrical connector of the electrical device 400, thereby improving the reliability of the electrical connection between the battery 200 and the electrical device 400.

[0060] It should be noted that the battery tray 100 of this application can be applied not only to the battery device 300 and electrical equipment 500 mentioned above, but also to devices or systems with exposed electrical connectors. The battery tray 100 of this application can prevent external substances from directly contacting the electrical connectors, protect the electrical connectors, thereby improving the reliability of the device or system and extending its service life.

[0061] Please refer to Figure 4, which shows a structural schematic diagram of a battery tray 100 with connector 30 provided in some embodiments of this application from one perspective.

[0062] In some embodiments, the battery tray 100 includes a plurality of mounting holes 23 and a plurality of first protective members 40. Each first protective member 40 is arranged around at least one mounting hole 23, and a first reinforcing rib 51 is provided between two adjacent first protective members 40. Adjacent first protective members 40 are connected by the first reinforcing rib 51 to improve the overall strength of the first protective members 40, thereby ensuring the protective effect of the connector 30.

[0063] In some embodiments, as shown in FIG4, the first side beam 20 of the battery tray 100 is provided with two mutually spaced mounting holes 23, and two first protective members 40 are respectively arranged around the outside of 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, and 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 members 40, so as to ensure the protective effect of the connector 30.

[0064] In other embodiments, the first side beam 20 of the battery tray 100 may be provided with more connectors 30, and a first protective member 40 may be arranged around the outside of the plurality of mounting holes 23, which can also protect the connectors 30.

[0065] In some embodiments, a first protective member 40 is disposed around the periphery of 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. The arrangement of one first protective member 40 around the periphery of another first protective member 40, providing multiple layers of first protective members 40, ensures the protective effect of the connector 30.

[0066] In some embodiments, a first protective member 40 is arranged around the periphery of a plurality of first protective members 40, and the plurality of first protective members 40 on the relatively inner side are connected by a first reinforcing rib 51. Each first protective member 40 on the relatively inner side is connected to the first protective member 40 on the relatively outer side by a second reinforcing rib, thereby improving the overall strength of the first protective member 40 and ensuring the protective effect of the connector 30.

[0067] In some embodiments, the length of the first protective member 40 is greater than the length of the connector 30 protruding from the first side beam 20 in a direction away from the battery housing cavity 11.

[0068] In some embodiments, the distance between the end of the first protective member 40 away from the battery housing cavity 11 and the end of the connector 30 away from the battery housing cavity 11 is in the range of 15mm-25mm.

[0069] In some embodiments, the distance between the first protective member 40 and the mounting hole 23 along the extension direction perpendicular to the first protective member 40 ranges from 10mm to 50mm.

[0070] Please refer to Figures 5-8, where Figure 5 illustrates a structural schematic diagram of the battery tray 100 with connector 30 provided in some embodiments of this application from another perspective; Figure 6 illustrates a cross-sectional schematic diagram of the battery tray 100 with connector 30 provided in some embodiments of this application; Figure 7 illustrates a partially enlarged cross-sectional schematic diagram of one side of the battery tray 100 with connector 30 provided in some embodiments of this application; and Figure 8 illustrates a partially enlarged cross-sectional schematic diagram of the other side of the battery tray 100 with connector 30 provided in some embodiments of this application.

[0071] In some embodiments, the battery tray 100 includes a connector 21, a portion of which is connected to the first side beam 20 and extends toward the battery receiving cavity 11. The connector 21 is located outside the first protective member 40 and is used to connect the base plate 10 and / or the electrical device 400.

[0072] In some embodiments, a third reinforcing rib 52 is provided between the connector 21 and the first protective member 40. The connector 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 protective effect of the connector 30.

[0073] In some embodiments, as shown in Figures 5-8, the connector 21 is fixed to the first side beam 20 and extends toward the bottom plate 10, so that the connector 21 is fixed to the bottom plate 10 to achieve a fixed connection between the first side beam 20 and the bottom plate 10.

[0074] In other embodiments, the connector 21 is fixed to the first side beam 20 and extends toward the side away from the battery housing 11 for securing an external electrical device 400.

[0075] In other embodiments, the connector 21 includes a side connector 22 located on the side of the first side beam 20 away from the battery cavity and on the outside of the first protective member 40. Along the direction away from the battery cavity 11, the length of the side connector 22 is greater than the length of the first protective member 40. The side connector 22 is used to fix the electrical device 400.

[0076] In some embodiments, as shown in FIG5, the side connectors 22 extend toward the side away from the battery housing cavity 11, and each side connector 22 is provided with a connection hole for connecting an external electrical device 400. Referring to FIG2, a third reinforcing rib 52 is provided between the side connector 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 protective effect of the connector 30.

[0077] Understandably, along the extension direction perpendicular to the connector 30, the side connector 22 also partially covers the first protective member 40, and can also protect the first protective member 40.

[0078] In some embodiments, the first protective member 40, the connector 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, as well as the connection strength between the connector 21 and the first side beam 20, thereby ensuring the protective effect of the connector 30.

[0079] In some embodiments, as shown in FIG5, the first protective member 40, the connector 21 for fixing the base plate 10, the side connector 22 for fixing the external electrical device 400, 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 connector 21 and the first side beam 20, and the connection strength between the side connector 22 and the first side beam 20, thereby ensuring the protective effect of the connector 30.

[0080] In some embodiments, the battery tray 100 includes a base plate 10 and a plurality of second side beams 24, the first side beams 20 and the plurality of second side beams 24 being connected in sequence to form a frame, and the base plate 10 being connected to the frame to enclose the battery receiving cavity 11.

[0081] In some embodiments, as shown in Figures 6-8, 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 together form a frame, which is connected to the base plate 10 to form a battery receiving 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 it.

[0082] In some embodiments, the distance between the end of the side connector 22 away from the battery cavity 11 and the end of the first protective member 40 away from the battery cavity 11 is in the range of 30mm-50mm along the direction away from the battery cavity 11.

[0083] In some embodiments, the side connector 22 is located on one side of the first protective member 40 along the direction of the battery receiving cavity 11 toward the base plate 10.

[0084] In some embodiments, the distance between the side connector 22 and the first protective member 40 along the arrangement direction of the battery receiving cavity and the base plate 10 ranges from 2mm to 10mm.

[0085] In some embodiments, as shown in FIG6, a partition is fixed in the middle of the base plate 10. The partition is parallel to the first side beam 20 and the second side beam 24 and is used to separate the area within the battery tray 100 for accommodating the battery 200.

[0086] Please refer to Figures 9 and 10, wherein Figure 9 illustrates another cross-sectional view of a battery tray with connector 30 provided in some embodiments of the present application; and Figure 10 illustrates a partially enlarged cross-sectional view of a battery tray with connector 30 provided in some embodiments of the present application.

[0087] In some embodiments, the battery tray 100 includes a second protective member 41, which is connected to the side of the first side beam 20 away from the battery receiving cavity 11 and surrounds the periphery of the mounting hole 23, and extends toward the battery receiving cavity.

[0088] In some embodiments, as shown in Figures 9 and 10, the other end of the connector 30 extends toward the battery housing cavity 11 and protrudes beyond the first side beam 20. The second protective member 41 is arranged around the periphery of the other end of the connector 30 and shields part of the other end of the connector 30 that protrudes from the first side beam 20, thereby protecting the other end of the connector 30.

[0089] Understandably, when the battery 200 is connected to the connector 30, the second protective member 41 restricts the displacement between the battery 200 and the connector 30 to prevent the relative movement of the battery 200 from damaging the connector 30. In some embodiments, as shown in FIG10, the connector 30 includes a through section 31, which is embedded in the first side beam 20 and located between the two ends of the connector 30. The size of the through section 31 is smaller than the size 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.

[0090] In other embodiments, the two ends of the connector 30 are of different sizes. The larger end of the connector 30 is fixed to the first side beam 20 by fasteners, which can also limit 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.

[0091] In some embodiments, as shown in FIG10, the dimension of the end of the connector 30 facing the battery receiving cavity 11 is larger than the dimension of the end away from the battery receiving cavity 11. The end of the connector 30 facing the battery receiving cavity 11 is fixed to the first side beam 20 by fasteners to ensure the connection between the connector 30 and the first side beam 20.

[0092] Please refer to Figures 11-15, where Figure 11 illustrates a structural schematic diagram of the battery tray 100 provided in some embodiments of this application from another perspective; Figure 12 illustrates an exploded schematic diagram of the protective plate 60 provided in some embodiments of this application; Figure 13 illustrates a cross-sectional schematic diagram of the protective plate 60 provided in some embodiments of this application; Figure 14 illustrates a partially enlarged cross-sectional schematic diagram of the protective plate 60 provided in some embodiments of this application; and Figure 15 illustrates a structural schematic diagram of the protective plate 60 provided in some embodiments of this application.

[0093] In some embodiments, the battery tray 100 includes a protective plate 60, which is connected to the side of the frame away from the battery receiving cavity 11 and located on the side of the base plate 10 away from the battery receiving cavity 11.

[0094] In some embodiments, as shown in FIG11, the battery tray 100 includes a protective plate 60, which is fixed to the side of the base plate 10 away from the battery receiving cavity 11. The protective plate 60 is used to protect the base plate 10 of the battery tray 100 and prevent damage to the base plate 10, thereby exposing the battery 200 in the battery tray 100.

[0095] In some embodiments, the strength of the protective plate 60 is greater than the strength of the base plate 10 to protect the base plate.

[0096] In some embodiments, as shown in Figures 7 and 11, the protective plate 60 extends to the side of the first side beam 20 away from the battery receiving cavity 11. Along the direction away from the battery receiving 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 receiving cavity 11 so that the protective plate 60 can also protect the first protective member 40, thereby ensuring the protective effect of the connector 30.

[0097] In some embodiments, as shown in FIG12, the protective plate 60 is composed of a first protective layer 61, a honeycomb plate 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 work together to form a protective layer to separate the honeycomb plate 62 and the metal plate 63 from the outside environment.

[0098] Understandably, isolating the metal plate 63 from the outside environment can slow down the corrosion process and extend the service life of the protective plate 60.

[0099] In some embodiments, the first protective layer 61 and / or the second protective layer 64 are made of glass fiber to improve the overall strength of the protective plate 60.

[0100] In some embodiments, as shown in Figures 13-15, the protective plate 60 has a first boss 601 and a second boss 602 on both sides. Referring to Figures 7 and 8, the connecting members 21 on both sides form a mating groove with the base plate 10 to accommodate the first boss 601. The first boss 601 is at least partially located in the mating groove, limiting the relative displacement between the base plate 10 and the protective plate 60, and ensuring that the protective plate 60 can cover the base 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.

[0101] In some embodiments, along the direction away from the first side beam 20, the distance between the first protective member 40 and the connector 30 on the side facing the base plate 10 increases, causing the first protective member 40 to tilt away from the connector 30, so that the sand, gravel or liquid accumulated between the connector 30 and the first protective member can be discharged by gravity.

[0102] In some embodiments, the battery tray 100 includes a protective cover connected to the first protective member 40. Along the extension direction of the connector 30, the protective cover completely covers the connector 30. The protective cover is used to protect the connector 30 when the battery tray 100 is not connected to an external electrical device 400.

[0103] In some embodiments, the protective cover is provided with a through hole, the outline and size of which match the outline and size of the electrical connector of the external electrical device 400.
