[0003] Currently, new energy vehicles mainly include hybrid vehicles and pure electric vehicles. In the research and development of new energy vehicles, pure electric new energy vehicles are still the mainstream of future development.

[0004] However, due to the current reality of low battery energy density, in order to meet the cruising range requirements of electric logistics vehicles, manufacturers often need to install multiple battery packs. Currently, most of the battery packs are directly bolted to the existing floor skeleton channel steel on the lower layer of the vehicle frame. During the installation process, a lifting mechanism such as a forklift is required for positioning and installation. The operation is cumbersome and the positioning adjustment time is long. In addition, the battery pack is in direct contact with the installed floor skeleton, and it is more difficult to move due to sliding friction. Therefore, the inherent installation structure is not convenient for the installation operation and later maintenance of the battery. Summary of the Invention

[0028] The following describes the specific embodiments of the present invention with reference to the accompanying drawings.

[0029] Such as Figures 1 to 7As shown in the figure, a battery mounting bracket for a vehicle in this embodiment is rectangular, composed of two short cross beams 17 and two long mounting beams 1. A connecting beam 18 is connected to the middle of the two mounting beams 1. The cross beam 17 and the connecting beam 18 are connected by a reinforcing beam 19. A positioning block 20 is provided on one side of the cross beam 17. The upper surfaces of the cross beam 17, the connecting beam 18, the reinforcing beam 19 and the mounting beam 1 are flush. Rubber pads 21 are also distributed on the upper surfaces of the cross beam 17 and the connecting beam 18. Among them, mounting grooves 2 extending along the length direction are respectively formed on the mounting beam 1. A plurality of rollers 3 with the same rolling direction rotate in the mounting grooves 2. The circumferential surface of the rollers 3 is higher than the upper edge of the mounting grooves 2. The battery rolls along the rollers 3 until it contacts the positioning block 20, completing the movement of the battery and reducing the physical effort of workers during the battery installation process;

[0030] A swing device corresponding to the number of rollers is further provided in the mounting beam 1. The swing device includes a swing arm 4 and a driving mechanism. The roller 3 rotates at one end of the swing arm 4. The axis of the roller 3 is parallel to the axis of the rotating shaft 5. The other end of the swing arm 4 rotates on the inner walls of both sides of the mounting groove 2 through the rotating shaft 5. The driving mechanism can drive the swing arm 4 to rotate so that the circumferential surface of the roller 3 is lower than the upper edge of the mounting groove 2. When the battery moves in place, the driving mechanism drives the swing arm 4 to rotate downward. The circumferential surface of the roller 3 is lower than the upper edge of the mounting groove 2. The bottom of the battery falls on the rubber pad 21 of the mounting bracket, and the roller 3 has no contact with the battery, avoiding accidental movement of the battery and ensuring accurate positioning of the battery position.

[0031] Specifically, the driving mechanism includes a gear 6 and a rack 7 that mesh with each other. The gear 6 is connected to the rotating shaft 5. The rack 7 extends along the length direction of the mounting groove 2 and meshes with a plurality of gears 6 in the same mounting beam 1 at the same time. An operation cavity 8 is further provided on one side of the mounting groove 2 in the mounting beam 1. The gear 6 and the rack 7 are arranged in the operation cavity 8. One end of the rotating shaft 5 penetrates the side wall of the mounting groove 2 and extends into the operation cavity 8. The gear 6 is sleeved outside the rotating shaft 5. A slide rail 9 extending along the length direction of the mounting groove 2 is provided in the operation cavity 8. The rack 7 slides on the slide rail 9. Moving the rack 7 along the slide rail 9 drives a plurality of gears 6 to rotate synchronously, thereby driving a plurality of swing arms 4 to swing downward synchronously through the rotating shaft 5, improving the efficiency.

[0032] Specifically, an operating mechanism is further provided on the battery mounting bracket. Preferably, the operating mechanism is located on one side of the positioning block 20. When it is observed that the battery contacts the positioning block 20, the operating mechanism can be directly operated here, which is more convenient. The operating mechanism includes a handle 10, a connecting column 11, and a fixed cylinder 12. The fixed cylinder 12 is fixed to the mounting beam 1. The axis of the fixed cylinder 12 is arranged along the length direction of the slide rail 9. The inner cavity of the fixed cylinder 12 communicates with the operating cavity 8. The connecting column 11 is threadedly connected to the fixed cylinder 12. One end of the connecting column 11 rotates on the rack 7, and the other end of the connecting column 11 extends out of the fixed cylinder 12 and is connected to the handle 10. The inner diameter of the fixed cylinder 12 is larger than the width of the rack 7. A rotating column 13 is provided on the rack 7. The diameter of the rotating column 13 is larger than the width of the rack 7. A receiving groove capable of accommodating the rotation of the rotating column 13 is provided on the end face of the connecting column 11. The rotating column 13 can extend into the fixed cylinder 12 and rotate in the receiving groove through a bearing. By rotating the connecting column 11 with the handle 10, under the action of the thread, the connecting column 11 generates an axial displacement. While the connecting column 11 rotates around the rotating column 13, it can drive the rotating column 13 and the rack 7 to generate a linear displacement, thereby driving the gear 6 to rotate, and realizing the synchronous downward swing of the rollers 3 in the same mounting beam 1.

[0033] Among them, both ends of the operating cavity 8 along the length direction of the mounting groove 2 form openings. The slide rail 9 is located at the inner top of the operating cavity 8. The rack 7 is located above the gear 6. The fixed cylinder 12 is located at the top of the operating cavity 8 at the positioning block 20. The diameter of the fixed cylinder 12 is smaller than the longitudinal height of the operating cavity 8. A gap is left between the fixed cylinder 12 and the bottom of the operating cavity 8. The swing arm 4 is inclined. The upper end of the swing arm 4 is connected to the roller 3, and the lower end of the swing arm 4 is connected to the rotating shaft 5. The distance from the roller 3 to the positioning block 20 is greater than the distance from the rotating shaft 5 to the positioning block 20. At this time, moving the rack 7 in the direction away from the positioning block 20 drives the gear 6 to rotate in the direction away from the positioning block 20, thereby driving the swing arm 4 to swing downward. An auxiliary slide rail 14 having the same structure as the slide rail 9 is further provided at the inner bottom of the operating cavity 8. An auxiliary rack 15 sliding on the auxiliary slide rail 14 is further engaged below the gear 6. The auxiliary rack 15 moves synchronously and in the opposite direction to the rack 7. An observation area 16 with a significantly different color is further provided at the end of the auxiliary rack 15 close to the fixed cylinder 12. The observation area 16 has a certain length along the length direction of the mounting groove 2. When moving the rack 7 in the direction away from the positioning block 20, the auxiliary rack 15 moves in the direction close to the positioning block 20. When the circumferential surface of the roller 3 is lower than the upper edge of the mounting groove 2, at this time, the entire observation area 16 is located outside the gap. On the contrary, when the entire observation area 16 is located inside the gap, the circumferential surface of the roller 3 is higher than the upper edge of the mounting groove 2. By observing the observation area 16, it is very convenient to judge whether the roller 3 is higher or lower than the upper edge of the mounting groove 2, and the operation is more convenient.

[0034] The working principle of the present invention:

[0035] Before moving the battery, by rotating the handle 10, the rack 7 is pulled to move towards the positioning block 20, driving the gear 6 to rotate towards the positioning block 20, thereby driving the swing arm 4 to swing upward. At this time, the auxiliary rack 15 moves away from the positioning block 20 until the entire observation area 16 is located within the gap, and the circumferential surface of the roller 3 is higher than the upper edge of the mounting groove 2; Place the battery on the mounting bracket and push the battery along the roller 3 until it contacts the positioning block 20 to complete the positioning of the battery;

[0036] Rotate the handle 10 in the reverse direction, push the rack 7 to move away from the positioning block 20, drive the gear 6 to rotate away from the positioning block 20, thereby driving the swing arm 4 to swing downward. At this time, the auxiliary rack 15 moves towards the positioning block 20 until the entire observation area 16 is located outside the gap and then stops. The circumferential surface of the roller 3 is lower than the upper edge of the mounting groove 2, and the bottom of the battery falls on the mounting bracket. The roller 3 has no contact with the battery, avoiding accidental movement of the battery and ensuring accurate positioning of the battery position.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
