[0036] Some embodiments of the present application are described in detail below with reference to the accompanying drawings. Unless there is any contradiction, those skilled in the art may combine and combine the different embodiments or examples and features of the different embodiments or examples described in this specification.

[0037] Please also see Figure 1 and Figure 2 , an embodiment of the present application provides a battery holder mechanism 100, a battery device 300 equipped with the battery holder mechanism 100, and a transport vehicle 400 equipped with the battery device 300. The transport vehicle 400 refers to a tool for transporting passengers and goods, such as a vehicle, a manned aircraft, a ship, etc. In the present application, the transport vehicle 400 can be a vehicle, which refers to a vehicle driven or towed by a power unit for passengers or for transporting goods, including but not limited to cars, sports utility vehicles (SUV), multi-purpose vehicles (MPV), buses, trucks, etc. In the following, the transport vehicle 400 is introduced as a vehicle as an example.

[0038] The battery assembly 300 includes a battery 200 and the aforementioned battery holder mechanism 100. The battery 200 is mounted within the transport vehicle 400 via the battery holder mechanism 100 and is used to power electronic devices within the transport vehicle 400. The battery 200 can be a low-voltage battery with a voltage less than or equal to 36V. In this embodiment, the battery 200 is a 12V lithium battery.

[0039] In this embodiment, the transport vehicle 400 may include a body 401 and the aforementioned battery device 300. Specifically, when the transport vehicle 400 is a vehicle, the body 401 may be a vehicle body. The body 401 may be provided with a cockpit 4010, which is used to seat the driver, so that the driver can control the transport vehicle 400 through a control system (e.g., a center console, a drive system, a braking system, etc.) provided in the cockpit 4010. The cockpit 4010 may be equipped with electronic devices such as audio equipment, a smart display screen, and a wireless or wired charging station. The battery 200 of the battery device 300 is used to power these electronic devices.

[0040] In this embodiment, the vehicle body 401 may include a floor 403 and a frame (not shown) connected to the floor 403. The floor 403 and the frame together define a cockpit 4010. The battery support mechanism 100 is fixedly connected to the floor 403 to mount the battery 200 on the floor 403. In this embodiment, the floor 403 may include a front floor 4032 and a rear mounting beam 4034. The front floor 4032 is generally plate-shaped and has a plurality of reinforcing ribs provided thereon to enhance structural strength. The rear mounting beam 4034 may be integrally formed on the side of the front floor 4032 near the vehicle seats and protrude relative to the front floor 4032. Figure 3 The floor panel 403 may be provided with a coating leakage hole 4011, located on the side of the front floor panel 4032 near the rear mounting beam 4034. During the painting process, the vehicle's body-in-white (BIW) is immersed in an electrophoretic bath for corrosion protection. Because the BIW is welded together from thin sheets, it features numerous closed-loop structures, which easily form cavities within the body. The coating leakage hole 4011 ensures that the electrophoretic fluid can fully contact the body and enter these cavities. It also ensures that the electrophoretic fluid quickly leaves the cavity when the BIW leaves the electrophoretic bath, ensuring the normal production cycle.

[0041] See also Figure 4In some embodiments, the transport vehicle 400 may further include a seat 405, which is fixed to the floor 403, with a space between the seat cushion portion of the seat 405 and the floor 403. The battery device 300 is located below the seat 405, utilizing the space below the seat 405. In some possible embodiments, the battery holder mechanism 100 may be disposed in an armrest box (not shown) located on one side of the seat 405 to conserve space within the cockpit 4010.

[0042] Please also see Figure 2 and Figure 5 In this embodiment, the battery holder mechanism 100 may include a tray 10, a bracket 30 and a connecting assembly 50. The tray 10 is provided with a avoidance notch 101, and the tray 10 is used to be set on the floor 403 and cover part of the structure of the floor 403. When the tray 403 is set on the floor 403, the avoidance notch 101 is located above the paint leakage hole 4011 to allow the paint leakage hole 4011 to be exposed. The bracket 30 is detachably connected to the tray 10 and is used to be fixedly connected to the floor 403. The connecting assembly 50 may include a plurality of connectors, and the plurality of connectors are distributed on the tray 10 and the bracket 30 for connecting the battery 200. The plurality of connectors are also used to connect the tray 10 and the bracket 30 to the floor 403. When the battery 200 is installed on the floor 403 through the tray 10, the avoidance notch 101 is covered.

[0043] Therefore, in the embodiment provided in the present application, the battery holder mechanism 100 is used to install the battery 200 on the floor 403 of the transport vehicle 400, so that the battery 200 is not directly installed on the floor 403, but is indirectly installed on the floor 403 through the battery holder mechanism 100 as an intermediate medium. In this way, during the installation process, the battery 200 can be first installed on the battery holder mechanism 100, and then the battery holder mechanism 100 can be installed on the floor 403. The battery holder mechanism 100 provides an installation and connection connection component 50, which can provide an extended operating space for the installation of the battery 200, and the installation operation is relatively convenient.

[0044] Furthermore, the tray 10 of the battery holder mechanism 100 is used to be stacked on the floor 403 of the transport vehicle 400. The tray 10 is provided with a clearance notch 101. The clearance notch 101 is located above the paint leakage hole 4011 to allow the paint leakage hole 4011 to be exposed. When the battery 200 is installed on the tray 10, the clearance notch 101 is covered. When the battery 200 is installed on the floor 403 via the battery holder mechanism 100, the space above the paint leakage hole 4011 is also covered. Therefore, the battery 200 is equivalent to being installed above the paint leakage hole 4011 without having to avoid the paint leakage hole 4011. Even if the floor 403 is uneven, the battery 200 can be connected to other parts of the floor 403, such as a flat part, through the bracket 30 and the tray 10, so that the battery 200 can be firmly installed on the floor 403. Therefore, in the transport vehicle 400 provided in the present application, the battery 200 can be installed on the floor 403 through the battery holder mechanism 100. The installation position of the battery 200 is not restricted by the uneven structure of the floor 403. Its installation position is more flexible and has wider applicability. The connection to the floor 403 is achieved through the battery holder mechanism 100, and the connection strength is also relatively high.

[0045] In this embodiment, the tray 10 is connected to the floor 403 and is used to support the battery 200. Specifically, the tray 10 is connected to the front floor 4032 and has an extended structure within a plane (e.g., the plane of the front floor 4032). The tray 10 may be provided with concave or convex ribs to enhance strength or to adapt to the unevenness of the front floor 4032. As an example, the front floor 4032 is provided with at least two mutually spaced reinforcing ribs 4036. The at least two reinforcing ribs 4036 are integrally formed with the front floor 4032 and protrude relative to the front floor 4032. Correspondingly, the tray 10 in this embodiment may include an embedded portion 121 and at least two overlapping portions 123. The embedded portion 121 is provided between two adjacent overlapping portions 123 and protrudes relative to the overlapping portions 123. When the pallet 10 is placed on the floor 403, the embedded portion 121 is embedded between two adjacent reinforcing ribs 4036, and the overlapping portion 123 is overlapped on the reinforcing ribs 4036. Here, "overlap" is understood to mean that the overlapping portion 123 and the reinforcing ribs 4036 of the pallet 10 may partially overlap, or there may be a slight gap between the overlapping portion 123 and the reinforcing ribs 4036, or the two may be directly attached.

[0046] The arrangement of the embedded portion 121 and the overlapping portion 123 allows the shape of the pallet 10 to match that of the front floor panel 4032, thereby improving the stability of the connection between the pallet 10 and the front floor panel 4032. Furthermore, the overlapping portion 123 also serves as a reinforcing rib for the pallet 10, thereby increasing the structural strength of the pallet 10. The pallet 10 is formed using a stamping process to form the undulating structure of the embedded portion 121 and the overlapping portion 123. In this embodiment, there are two overlapping portions 123. Both the embedded portion 121 and the two overlapping portions 123 extend along the travel direction of the transport vehicle 400. The embedded portion 121 is located between the two overlapping portions 123. The overlapping portions 123 and the embedded portion 121 are aligned along the width of the transport vehicle 400.

[0047] In the description of this application, it should be understood that terms such as "length", "width", "thickness", "up", "down", "front", "back", "left", "right", and "inside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only used to simplify the description for the convenience of describing this application, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on this application.

[0048] Please also see Figure 6 and Figure 7 In this embodiment, the tray 10 may include a plate body 12 and a connector mounting portion 14 provided on the plate body 12, an embedding portion 121 and a stacking portion 123 provided on the plate body 12. The shape of the plate body 12 fits the front floor 4032, and the plate body 12 follows the protrusion of the front floor 4032 (such as Figure 5 The portion of the plate 12 that is raised due to the reinforcement ribs 4036 shown in the figure forms the aforementioned overlapping portion 123, and the portion of the plate 12 that is recessed due to the recess of the front floor 4032 (between two adjacent reinforcement ribs 4036) forms the aforementioned embedded portion 121. The plate 12 has a first surface 1201 and a second surface 1203 that are opposite to each other. The first surface 1201 is stacked on the front floor 4032, and the second surface 1203 is used to support the battery 200. The plate 12 is connected to the front floor 4032. In this embodiment, the plate 12 can be connected to the front floor 4032 by welding (as shown in the figure). Figure 2 As shown), the stability between the pallet 10 and the floor 403 is improved.

[0049] A clearance notch 101 is formed in the plate 12 and extends through the plate 12 along its thickness. When the plate 12 is stacked on the front floor 4032, the clearance notch 101 is positioned opposite the paint leak hole 4011. The presence of the paint leak hole 4011 leaves the tray 10 unsupported at this location. Providing the clearance notch 101 opposite the paint leak hole 4011 reduces the overall weight of the tray 10. The bracket 30 can cover the clearance notch 101 of the tray 10, providing a secure point for the battery 200.

[0050] The connector mounting portion 14 is a raised structure provided on the second surface 1203. Specifically, the connector mounting portion 14 is provided on the overlapping portion 123 and protrudes relative to the overlapping portion 123. The connector mounting portion 14 is configured to connect with the connection assembly 50 and can also be connected to the front floor panel 4032. For example, the connector mounting portion 14 can be welded to the front floor panel 4032. Multiple connector mounting portions 14 can be provided. In this embodiment, the number of connector mounting portions 14 can be adjusted based on the installation requirements of the battery 200. This specification does not limit the connection method between the connector mounting portion 14 and the plate body 12. For example, the connector mounting portion 14 and the plate body 12 can be integrally formed, or the connector mounting portion 14 can be welded to the plate body 12. In this embodiment, the tray 10 is a stamped structural member, and the connector mounting portion 14 is integrally formed with the plate body 12. The tray 10 can be provided with multiple stamped structural ribs (such as the at least two overlapping portions 123 described above).

[0051] Please also see Figure 2 、 Figure 5 and Figure 8 In this embodiment, the bracket 30 is connected to the tray 10 and the floor 403, and the bracket 30 is used to cooperate with the tray 10 to support the battery 200. The bracket 30 may include a connecting portion 32 and a avoidance reinforcement portion 34, and the connecting portion 32 and the avoidance reinforcement portion 34 are connected to each other. The connecting portion 32 is superimposed on one side of the tray 10 and is connected to the tray 10 through at least one connecting member. The avoidance reinforcement portion 34 is arranged corresponding to the avoidance gap 101 and covers at least part of the vacant portion of the avoidance gap 101. When the tray 10 is set on the floor 403, the avoidance reinforcement portion 34 is opposite to the paint leakage hole 4011 in the air. The avoidance reinforcement portion 34 of the bracket 30 covers at least part of the vacant portion of the avoidance gap 101, and the avoidance reinforcement portion 34 is opposite to the paint leakage hole 4011 (such as Figure 3 As shown) they are spaced apart from each other and cover part of the space above the paint leakage hole 4011, so that the battery 200 can be installed above the paint leakage hole 4011 through the bracket 30 without having to avoid the paint leakage hole 4011. The installation position of the battery 200 is not restricted by structures such as the paint leakage hole 4011 on the floor 403, and its installation position is more flexible and has a wider applicability.

[0052] The connecting portion 32 is connected between the plate body 12 and the battery 200 via a connecting assembly 50. Specifically, the connecting portion 32 is superimposed on one of the overlapping portions 123 of the plate body 12 and is located at one end of the overlapping portion 123 near the rear mounting beam 4034. The avoidance reinforcement portion 34 is connected to the side of the connecting portion 32 near the embedded portion 121, and the avoidance reinforcement portion 34 is spaced apart from the embedded portion 121. The connecting portion 32 and the avoidance reinforcement portion 34 are connected continuously from the overlapping portion 123 to the embedded portion 121. The term "connected" can be understood as the smooth transition between the surfaces of the two adjacent portions, such as the two being located in the same plane or the curved surfaces defined by the two being continuous; or the two jointly forming a specific external appearance, such as a stepped structure, an angled structure, a curved surface structure, etc. In this embodiment, the surfaces of the connecting portion 32 and the avoidance reinforcement portion 34 smoothly transition between the adjacent portions. Due to the height difference between the overlapping portion 123 and the embedded portion 121, the whole composed of the connecting portion 32 and the avoidance reinforcement portion 34 is slightly sunken at the embedded portion 121, so that the connecting portion 32 fits into the surface of the overlapping portion 123, increasing the contact area between the bracket 30 and the tray 10, and improving the connection stability between the two.

[0053] In this embodiment, the bracket 30 may further include a beam mounting portion 36. The beam mounting portion 36 is connected to a side of the connecting portion 32 near the rear mounting beam 4034. The beam mounting portion 36 has a bent structure and is used to connect to the rear mounting beam 4034. The beam mounting portion 36 is connected between the connecting portion 32 and the rear mounting beam 4034. The bracket 30 is fixed to the rear mounting beam 4034 via the beam mounting portion 36, which improves the installation stability of the bracket 30 and thereby increases the connection and installation strength of the battery 200 on the bracket 30.

[0054] The beam mounting portion 36 may include a supporting sub-portion 361 and a connecting sub-portion 363. The supporting sub-portion 361 is located on one side of the connecting portion 32. The supporting sub-portion 361 is bent relative to the connecting portion 32 and extends away from the pallet 10. The connecting sub-portion 363 is connected to the end of the supporting sub-portion 361 away from the connecting portion 32 and is configured to be connected to the rear mounting beam 4034. The connecting sub-portion 363 may be connected to the rear mounting beam 4034 using fasteners such as screws and bolts. The supporting sub-portion 361 is configured to compensate for the height difference between the connecting portion 32 and the rear mounting beam 4034, allowing the connecting sub-portion 363 to rest on and be fixedly connected to the rear mounting beam 4034.

[0055] The bracket 30 can be formed by stamping to ensure high structural strength and stability. Therefore, although the connecting part 32, the avoidance reinforcement part 34 and the beam mounting part 36 use different names to refer to different parts of the bracket 30, these names should not be regarded as restrictions on the structure of the bracket 30. These names are only made for the convenience of description. For example, the connection between the connecting part 32, the avoidance reinforcement part 34 and the beam mounting part 36 can be an integrally formed connection structure, and there may be no obvious dividing line between the connecting part 32, the avoidance reinforcement part 34 and the beam mounting part 36. In other embodiments, the bracket 30 can be formed by assembly connection to reduce the difficulty of preparation. For example, the connecting portion 32, the avoidance reinforcement portion 34 and the beam mounting portion 36 can be prepared independently and then assembled together by fasteners to form the overall structure of the bracket 30. Among them, the connecting portion 32, the avoidance reinforcement portion 34 and the beam mounting portion 36 can be formed by casting respectively, and the connecting portion 32, the avoidance reinforcement portion 34 and the beam mounting portion 36 can be connected together by fasteners (such as screws, bolts, studs and other threaded fasteners) or / and adhesives such as structural adhesives.

[0056] In this embodiment, the bracket 30 is a stamped structural member and may be provided with multiple stamped structural ribs to enhance structural strength. The bracket 30 and the tray 10 are detachably connected, facilitating separate installation of the bracket 30 and the tray 10. Furthermore, the non-integrated structure of the bracket 30 and the tray 10 reduces material usage and overall weight.

[0057] Please also see Figure 4 、 Figure 5 and Figure 9 The battery 200 is connected to the tray 10 and the bracket 30 via the connecting assembly 50.

[0061] The battery 200 is installed on the tray 10 and the bracket 30. Since the bracket 30 is partially overlapped on the tray, in order to improve the installation balance of the battery 200, in this embodiment, the tray 10 is tilted and one end of the tray 10 connected to the bracket 30 can be slightly lower than the other end.

[0062] The battery holder mechanism 100 provided in the embodiment of the present application is used to install the battery 200 on the floor 403 of the transport vehicle 400, so that the battery 200 is not directly installed on the floor 403, but is indirectly installed on the floor 403 through the battery holder mechanism 100 as an intermediate medium. In this way, during the installation process, the battery 200 can be first installed on the battery holder mechanism 100, and then the battery holder mechanism 100 can be installed on the floor 403. The battery holder mechanism 100 provides a connecting component 50 for installation and connection. The beam mounting portion 36 of the bracket 30 extends toward the rear mounting beam 4036, which can provide an extended operating space for the installation of the battery 200, and the installation operation is relatively convenient.
