Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, and in particular to a vehicle battery pack mounting structure. This utility model also relates to a vehicle having the above-described vehicle battery pack mounting structure. Background Technology
[0002] With the rapid development of the electric vehicle industry, the requirements for the design and installation structure of vehicle battery packs are increasing. As a core component of electric vehicles, the battery pack not only directly affects the vehicle's range, but the rationality and reliability of its installation structure also affect the vehicle's overall performance, safety, and ease of maintenance. Traditional vehicle battery pack installation structures mostly adopt a fixed layout, that is, the battery pack is directly fixed to a predetermined position on the vehicle chassis.
[0003] However, most vehicles using this battery pack mounting method do not have battery swapping capabilities. Even if a small number of vehicles can swap batteries, they require specialized battery swapping equipment, making the process inconvenient. Utility Model Content
[0004] In view of this, the present invention aims to provide a vehicle battery pack mounting structure to facilitate the installation and removal of the battery pack.
[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0006] A vehicle battery pack mounting structure includes: two mounting boxes symmetrically arranged on both sides of a vehicle chassis, with a battery pack assembly opening on the side facing away from the vehicle chassis; a carrier hinged within the mounting boxes to support the battery pack; the battery packs stacked vertically within the mounting boxes; and the angle between the carrier and the horizontal plane adjustable to guide the battery packs toward or away from the vehicle chassis under gravity.
[0007] Furthermore, the end of the carrier away from the vehicle chassis is hinged to the mounting box, and a top support assembly is provided on the lower side of the end of the carrier near the vehicle chassis; the top support assembly is telescopically adjustable to adjust the angle between the carrier and the horizontal plane.
[0008] Furthermore, the top support assembly includes: a lead screw, which slides along its own axis through the mounting box and is supported at one end on the bottom of the carrier; and a rotating part, which is rotatably connected to the mounting box and threadedly connected to the lead screw.
[0009] Furthermore, the top support assembly also includes a worm gear rotatably connected to the mounting box; the rotating part is a worm wheel that meshes with the worm gear, and the lead screw passes through and is threadedly connected to the rotating part along the central axis of the rotating part.
[0010] Furthermore, the top support assembly is provided in multiple sets, and each of the worm gears is coaxially fixed together.
[0011] Furthermore, a gasket is provided between the mounting box and the top support assembly.
[0012] Furthermore, each of the mounting boxes contains two of the aforementioned carriers.
[0013] Furthermore, a connecting rod is hinged between the two carriers to maintain their parallelism.
[0014] Furthermore, the mounting box includes: a box body, fixedly connected to the vehicle chassis, with the mounting opening provided on the side opposite to the vehicle chassis; a box cover, hinged to the box body, rotatably covering the mounting opening, with its free end detachably locked to the box body; and / or, the carrier body is provided with rollers, the rollers abutting against the battery pack.
[0015] Compared with the prior art, this utility model has the following advantages:
[0016] The vehicle battery pack installation structure described in this utility model, by setting a carrier in the installation box and changing the tilt angle of the carrier, allows the battery pack to slide towards the vehicle chassis and be installed in place during installation due to the tilt of the carrier. During disassembly, the battery pack is removed from the installation box due to the tilt of the carrier moving away from the vehicle chassis, thus facilitating the installation and disassembly of the battery pack and enabling the vehicle's battery swapping function.
[0017] Secondly, a retractable top support assembly is provided, allowing the movable end of the top support assembly to support the load-bearing body, thereby adjusting the angle between the load-bearing body and the horizontal plane. The top support assembly includes a lead screw and a rotating part. The lead screw can be driven by the rotating part to move in the height direction, thereby changing the angle of the load-bearing body. Its structure is simple and reliable, and it can achieve self-locking. The top support assembly also includes a worm gear, and the rotating part can act as a worm wheel meshing with the worm gear. There is a large transmission ratio between the worm gear and the worm wheel.
[0018] In addition, multiple sets of top support assemblies are provided, and the worm gears of each top support assembly are coaxially fixed. The lead screws in each top support assembly can be raised and lowered synchronously to support the load-bearing body and adjust its angle. Gaskets are provided between the mounting box and the top support assembly to prevent the lead screws from damaging the load-bearing body. Each mounting box contains two load-bearing bodies, which facilitates the installation and removal of the battery pack and enables the partitioned assembly of the battery pack.
[0019] Furthermore, a connecting rod is hinged between the two carriers, so that adjusting the angle of either carrier will correspondingly change the angle of the other carrier, ensuring synchronized angle adjustments. The mounting box includes a body and a cover. The cover's locking connection with the body allows for opening and closing of the mounting box, and the cover also limits the battery pack's position, improving installation stability. Additionally, the carriers can be equipped with casters, allowing the battery pack to slide on them during installation or removal, facilitating both processes.
[0020] Another objective of this invention is to provide a vehicle having the vehicle battery pack mounting structure described above.
[0021] The vehicle and / or vehicle battery pack installation structure described in this utility model has the same technical effect as the prior art, and will not be described in detail here. Attached Figure Description

[0039] Example 1
[0040] This embodiment relates to a vehicle battery pack mounting structure, which includes a mounting box 1 and a carrier 3 in its overall structure. Wherein, as... Figure 1 , Figure 2 As shown, there are two mounting boxes 1, symmetrically arranged on both sides of the vehicle chassis 2, and the side of the mounting box 1 facing away from the vehicle chassis 2 has an assembly port for the battery pack. The battery pack in this embodiment is a modular design, meaning multiple battery packs can jointly power the vehicle. The carrier 3 is hinged inside the mounting box 1 and can support the battery pack. The battery packs are stacked vertically inside the mounting box 1, and the angle between the carrier 3 and the horizontal plane can be adjusted to guide the battery packs towards or away from the vehicle chassis 2 under gravity.
[0041] As described above, by setting the carrier 3 in the mounting box 1 and changing the tilt angle of the carrier 3, the battery pack can be installed in place by sliding towards the vehicle chassis 2 due to the tilt of the carrier 3 during installation. When removing the battery pack, the battery pack is removed from the mounting box 1 by tilting the carrier 3 away from the vehicle chassis 2, thus facilitating the installation and removal of the battery pack and enabling the vehicle's battery swapping function.
[0042] Based on the above overview, specifically, the vehicle battery pack installation structure of this embodiment, compared to the configuration where the battery pack is placed in the vehicle chassis 2, uses a mounting box 1 to place the battery pack on both sides of the vehicle chassis 2. This allows operators to directly access the battery pack from the outside of the vehicle, facilitating wiring, inspection, and maintenance. Simultaneously, the stacked arrangement of the battery packs within the mounting box 1 also increases the overall battery capacity of the vehicle to a certain extent, thereby improving its driving range.
[0043] To facilitate adjustment of the angle of the support body 3, such as Figure 3 As shown, in this embodiment, the end of the carrier 3 furthest from the vehicle chassis 2 is hinged to the mounting box 1, and a top support assembly 4 is provided on the lower side of the end of the carrier 3 closest to the vehicle chassis 2. The top support assembly 4 is telescopically oriented, and by setting the top support assembly 4, the movable end of the top support assembly 4 can support the carrier 3, change the height of the side furthest from the hinged end of the carrier 3, so as to adjust the angle between the carrier 3 and the horizontal plane, and realize the tilting of the carrier 3.
[0044] Specifically, such as Figure 4 As shown, the top support assembly 4 in this embodiment includes a lead screw 401 and a rotating part 402. The lead screw 401 slides along its own axial direction on the mounting box 1, and one end of the lead screw 401 is supported on the bottom end of the carrier 3. The rotating part 402 is rotatably connected to the mounting box 1 and threadedly connected to the lead screw 401. With the lead screw 401 and the rotating part 402, when the rotating part 402 is driven to rotate, the lead screw 401 can be driven to move in the height direction, allowing the lead screw 401 to support the bottom end of the carrier 3, thereby causing the angle of the carrier 3 to change. Its structure is simple and reliable, and the transmission ratio between the lead screw 401 and the rotating part 402 is large, giving the top support assembly 4 a large driving force, which can effectively drive the carrier 3 carrying the battery pack to tilt. Furthermore, the lead screw 401 and the rotating part 402 are self-locking to keep the carrier 3 in an tilted state.
[0045] Furthermore, the top support assembly 4 in this embodiment also includes a worm gear 403 rotatably connected to the mounting box 1. The rotating part 402 itself constitutes a worm wheel and meshes with the worm gear 403. The lead screw 401 passes through and is threadedly connected to the rotating part 402 along the central axis of the rotating part 402. Through the meshing arrangement of the worm gear 403 and the rotating part 402, which acts as a turbine, there is a large transmission ratio between the worm gear 403 and the turbine, which has the characteristics of saving effort and easy rotation. This facilitates the lifting of the bearing body 3 by driving the lead screw 401 through the rotating part 402 by rotating the worm gear 403, further improving the driving force of the top support assembly 4. In addition, the self-locking between the worm gear 403 and the rotating part 402, which acts as a turbine, can further maintain the top support state of the lead screw 401. In order to assemble the top support assembly 4, the mounting box 1 is provided with a housing, and two thrust bearings are installed in the housing. The two thrust bearings clamp the rotating part 402 from both sides to constrain the rotating part 402 to only perform rotational movement of its own axis.
[0046] Because the carrier 3 has a large weight when loading the battery pack, multiple sets of top support components 4 are provided in this embodiment to effectively adjust the angle of the carrier 3, and the worm gears 403 of each top support component 4 are coaxially fixed. By setting multiple sets of top support components 4, the lead screws 401 in each top support component 4 can be raised and lowered synchronously to support the carrier 3 and realize the adjustment of the angle of the carrier 3, further improving the driving force for adjusting the angle of the carrier 3. In a specific implementation, the end plate of the worm gear 403 is formed with a hexagonal head 404 so that the operator can turn the worm gear 403 with a wrench.
[0047] Furthermore, to prevent the lead screw 401 in the top support assembly 4 from damaging the bottom surface of the carrier 3 during the adjustment of the angle of the carrier 3, a gasket 5 is provided between the mounting box 1 and the top support assembly 4 in this embodiment to prevent the top end of the lead screw 401 from directly contacting the carrier 3 and to prevent the carrier 3 from being damaged.
[0048] As a specific implementation, each mounting box 1 in this embodiment is provided with two carriers 3, and each carrier 3 can be equipped with a battery pack, which facilitates the installation and removal of the battery pack while realizing the partitioned assembly of the battery pack. In a specific implementation, one carrier 3 is located at the bottom of the mounting box 1, and the other carrier 3 is located in the middle of the mounting box 1.
[0049] In this embodiment, a connecting rod 301 is hinged between the two support bodies 3 to maintain their parallelism. Therefore, when the angle of either support body 3 is adjusted, the angle of the other support body 3 changes accordingly, ensuring synchronized angle adjustments. In practice, the upper support body 3 is directly supported by the top support assembly 4, while the lower support body 3 rests directly on the bottom of the mounting box 1. Furthermore, the connecting rod 301 can be configured as two rods, forming a parallelogram structure with the two support bodies 3, ensuring the stability of the upper support body 3 pulling the lower support body 3.
[0050] In this embodiment, the mounting box 1 includes a box body 101 and a box cover 102. The box body 101 is fixedly connected to the vehicle chassis 2, and the mounting opening is located on the side opposite to the vehicle chassis 2. The box cover 102 is hinged to the box body 101 and rotatably covers the mounting opening, with its free end detachably locked to the box body 101. The locking connection between the box cover 102 and the box body 101 allows the mounting box 1 to be opened and closed. The box cover 102 can limit the position of the battery pack, improving the stability of the battery pack installation. Simultaneously, the carrier 3 may be equipped with rollers 302, which abut against the battery pack. The rollers 302 allow the battery pack to slide easily on the carrier 3 during installation or removal, facilitating installation and removal. In a specific implementation, the box cover 102 of this embodiment is composed of longitudinal beams 1021 arranged at intervals and crossbeams 1022 connecting each longitudinal beam 1021. The top of the longitudinal beam 1021 is hinged to the box body 101, and the bottom of the longitudinal beam 1021 is provided with a latch 1023 for locking connection.
[0051] In summary, the vehicle battery pack installation structure of this embodiment, by setting the carrier 3 in the installation box 1 and changing the tilt angle of the carrier 3, allows the battery pack to slide into place towards the vehicle chassis 2 due to the tilt of the carrier 3 during installation. When removing the battery pack, the battery pack is removed from the installation box 1 due to the tilt of the carrier 3 away from the vehicle chassis 2. This facilitates the installation and removal of the battery pack, thereby enabling the vehicle's battery swapping function and demonstrating excellent practicality.
