Description

Technical Field

[0001] This utility model relates to the field of chassis battery replacement technology, and more specifically, to a quick-change mechanism for electric batteries in a skateboard chassis. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the skateboard chassis, as a highly integrated and modular vehicle platform technology, has attracted much attention because it can effectively reduce R&D costs, shorten the development cycle and improve space utilization.

[0003] The power battery is the core component of a vehicle, and it is also a potential source of failure and wear and tear. Throughout the vehicle's life cycle, the battery may need to be disassembled for repair, inspection or replacement due to cell failure, BMS (Battery Management System) malfunction, collision damage or simply performance degradation.

[0004] Currently, during battery disassembly and assembly, it has been found that the battery pack is fixed to the inside of the chassis by bolts. It is necessary to remove a large number of bolts from the bottom to release the fixation before disassembly can be carried out. This process is time-consuming and requires the chassis to be fixed in a high position to facilitate worker operation. The whole process is too cumbersome.

[0005] To address the aforementioned issues, this application proposes a quick-change mechanism for an electric battery in a skateboard chassis. Utility Model Content

[0006] The purpose of this invention is to provide a quick-change mechanism for electric batteries in skateboard chassis, which solves the problem that battery packs in the prior art are not conducive to quick replacement.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] A quick-change mechanism for electric batteries in a skateboard chassis includes a skateboard chassis and a sealing guard plate movably mounted on its lower end;

[0009] The skateboard chassis has an internal cavity for installing a battery pack, and sealing plates are movably installed at the upper and lower openings.

[0010] The skateboard chassis is provided with fixing mechanisms on both sides, and the fixing mechanism includes a fixing end and a control end;

[0011] The fixed end is a push plate with a connecting rod extending from its side. The rod passes through the body of the slide plate chassis and is plugged into the side plates on both sides of the sealing plate and the boss at the top of the sealing plate.

[0012] The control end is a screw, which is laterally rotatably installed inside the two sides of the slide plate chassis. The movable end of the screw forms an axial limit with the push plate.

[0013] The sealing plate has baffles protruding upwards on both sides, which cover both sides of the slide plate chassis to seal the screw inside and form a barrier.

[0014] Preferably, the skateboard chassis has mounting grooves and side grooves on both sides below, the push plate is laterally slidably installed inside the mounting groove, the screw is spirally connected to the skateboard chassis body between the mounting groove and the side groove, and the control end of the screw is located inside the side groove.

[0015] Preferably, a support plate is fixed at the bottom of the mounting groove to support the push plate in the fixed state.

[0016] Preferably, the skateboard chassis has grooves on the lower part of the area adjacent to the left and right inner sides for connecting the side plates.

[0017] Preferably, the axial limiting structure between the screw and the push plate includes a bushing, which is sleeved on the outside of the guide rod at the movable end of the screw.

[0018] Preferably, one end of the bushing has a support rod extending out and is helically connected to the threaded seat on the outer side of the push plate.

[0019] Preferably, the screw is a two-end structure with the body and guide rod separated, and the guide rod and screw are coaxially rotatably connected and mutually axially limit each other.

[0020] The beneficial effects of this utility model are:

[0021] 1. By integrating the fixing structure into both sides of the skateboard chassis, the push plate and connecting rod can be driven by operating the screws on both sides of the chassis when removing the battery pack, thereby locking and releasing the battery pack sealing plate. This avoids the trouble of raising the skateboard chassis to a high place. The overall operation is simple and facilitates quick battery pack replacement.

[0022] 2. By installing the sealing plate, the baffle forms an axial limit and seal on the screw operating end. Even under a lot of vibration, the screw position can be kept stable, thus ensuring the installation stability of the battery pack and avoiding connection loosening caused by vehicle vibration.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] A quick-change mechanism for electric batteries in a skateboard chassis is provided for quickly replacing the battery pack. By setting fixing mechanisms 2 on both sides of 1, the connecting rod 221 on one side of the push plate 22 is connected in series with the side plate 131, the skateboard chassis 11 body and the boss 132, thereby fixing the boss 132 and the battery pack above it in a predetermined position. The battery pack can be replaced without lifting 1. At the same time, the baffle 121 limits the fixing mechanism 2, so that the fixing mechanism 2 can maintain the stability of the structure under long-term vibration, thereby ensuring the stable installation of the battery pack.

[0035] In some embodiments, the specific structure of the skateboard chassis electric battery quick-change mechanism is as follows: Figure 1-5 As shown, it includes a skateboard chassis 11 and a sealing guard plate 12 below it;

[0036] The skateboard chassis 11 has an internal mounting cavity 1101 for installing a battery pack, and sealing plates 13 are movably installed at both the upper and lower openings and are connected and fixed by bolts.

[0037] Among them, the sealing plate 12 is located at the bottom of the skateboard chassis 11, covering the sealing plate 13 to form a sealed protection;

[0038] The fixing mechanism 2 is located on both sides of the skateboard chassis 11, and multiple of them are arranged at equal intervals in front and behind.

[0039] Fixed mechanism 2 includes a fixed part and a control part;

[0040] The fixed part includes a push plate 22, and a connecting rod 221 extends from the side of the push plate 22, with multiple rods arranged at equal intervals in the front and rear directions.

[0041] The control part includes a screw 21 and a bushing 23. The screw 21 and the bushing 23 are slidably connected, and the bushing 23 is spirally connected to the push plate 22.

[0042] Furthermore, mounting slots 1102 are provided on both sides of the bottom of the skateboard chassis 11 for mounting the push plate 22 and providing movement space;

[0043] In addition, the bottom of the slide plate chassis 11 body from the mounting groove 1102 to the mounting cavity 1101 is provided with a groove for mounting the side plates 131 on both sides of the sealing plate 13, and the body has a positioning hole that extends laterally through it, and the positioning hole extends to the inside of the two sides of the boss 132 above the sealing plate 13.

[0044] Furthermore, the connecting rod 221 moves laterally into and out of the positioning hole, realizing the three-section connection of the skateboard chassis 11 body, the side plate 131, and the boss 132, thereby fixing the sealing plate 13.

[0045] It should be noted that the battery pack is pre-fixed on top of the cover plate 13.

[0046] like Figure 4 and Figure 5 As shown, the control section of the screw 21 is located inside the side grooves 1103 opened on the left and right sides of the skateboard chassis 11.

[0047] Among them, the upper ends of both sides of the sealing plate 12 have baffles 121 protruding, which fill the outer area of ​​the side groove 1103, and are used to seal the internal space and to hold the screw 21 to prevent loosening.

[0048] like Figure 4 and Figure 5 As shown, a support plate 11021 is fixedly installed at the bottom of the mounting groove 1102, located on the side near the mounting cavity 1101, to support the push plate 22 and strengthen the fixing force.

[0049] It is understandable that an opening is formed between the end face of the support plate 11021 and the outer cross-section of the mounting groove 1102 for mounting the push plate 22.

[0050] It should be noted that after the push plate 22 is tilted, one end of the connecting rod 221 is inserted first, so that the push plate 22 can be installed inside the mounting groove 1102 and the connecting rod 221 can be inserted into the positioning hole.

[0051] like Figure 4 and Figure 5 As shown, the movable end of the screw 21 has a guide rod 211 extending out, which is sleeved with the center hole of the bushing 23;

[0052] One end of the bushing 23 has a support rod 231 extending out, which is screwed to the threaded seat 222 on the outer side of the push plate 22;

[0053] Understandably, by screwing in the screw 21 and pushing the bushing 23, the push plate 22 can be pushed so that the connecting rod 221 can be inserted into the positioning hole on the side of the boss 132; then screwing in the screws 21 in other areas to form a clamping fixation can fix multiple positions of the sealing plate 13.

[0054] like Figure 6 As shown, the screw 21 has a two-section structure. The screw 21 and the guide rod 211 are coaxially rotatably connected. The T-shaped stepped shaft and the T-shaped annular groove are rotatably connected, thereby forming mutual axial limiting, which can pull out the push plate 22 when the screw 21 is pulled.

[0055] Among them, the two-section screw 21 is only installed on one side of the skateboard chassis 11, located in the front and rear center areas.

[0056] The specific usage methods of the quick-change mechanism for the electric battery of the skateboard chassis, as disclosed in some publications, are as follows:

[0057] S1. When the battery pack needs to be disassembled, first remove the bolts at both ends of the left and right sides of the baffle 121 and take out the sealing plate 12. At this time, the battery pack remains fixed.

[0058] S2. Move the movable pallet to below the skateboard chassis 11 and lift the platform support plate 13 by hydraulic lifting.

[0059] S3. Rotate to remove the integrated screw 21, causing the guide rod 211 to disengage from the bushing 23, thereby releasing the limit on the push plate 22. At this time, the battery pack is still in a fixed state. Repeat this operation to remove all bushings 23.

[0060] S4. Disconnect the battery pack connection wire in the wiring area of ​​the skateboard chassis, then rotate and remove the two-section screw 21 in the front and rear center areas to drive the push plate 22 to move outward, so that the connecting rod 221 is separated from the boss 132 and the side plate 131, and the fixing of the sealing plate 13 is released. At this time, the battery pack can be separated from the mounting cavity 1101 as the moving pallet platform descends.

[0061] S5. When installing the battery pack, simply reverse the steps above.
