Technical Field
[0001] This utility model relates to the field of new energy battery technology, and more specifically, to a quick-swap new energy battery car body. Background Technology
[0002] A battery box is a group of batteries consisting of several individual batteries, a box body, a battery management system, and related installation structural components (equipment). It has a standard battery box structure, battery box monitoring equipment, battery box connectors, and battery box environmental control equipment.
[0003] The existing battery packs in automobiles are all installed as a whole, which makes it inconvenient to disassemble and replace them quickly. This results in low replacement efficiency, poor performance, and is not conducive to the use of the car. In addition, when the car is in motion, the body will shake, which will cause the batteries inside the battery pack to collide, resulting in battery damage and leakage, which is unsafe.
[0004] A search revealed a Chinese patent, CN216624446U, which discloses a quick-change new energy battery car body. This utility model facilitates the cooperation between the inner and outer battery housings, enabling stable positioning of the inner battery housing. During vehicle operation, the snap-fit plate can be used to limit and fix the fixing plate, preventing the inner battery housing from shifting or colliding due to vehicle shaking, thereby improving its stability and preventing collision damage and leakage.
[0005] However, in actual use, when replacing individual batteries inside the battery pack, the entire battery pack needs to be removed. During repeated installations, the batteries need to be repositioned, making the installation of the battery pack quite complicated. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a quick-swap new energy battery vehicle housing to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A quick-swap new energy battery vehicle housing includes an outer housing, an inner housing inside the outer housing, and a battery positioning mechanism inside the inner housing. The battery positioning mechanism includes multiple first positioning plates, both ends of which are fixedly connected to the inner wall of the inner housing. Two guide rods are slidably connected inside the inner housing, and multiple second positioning plates are fixedly connected inside each of the two guide rods. Multiple second buffer pads are fixedly connected to one side of each second positioning plate, and a pull rod is fixedly connected to one side of each guide rod. Multiple gaskets are installed inside the inner housing, and multiple limiting brackets are fixedly connected to the inner wall of the inner housing. Pins are inserted into the limiting brackets. Multiple batteries are disposed inside the inner housing. Two pull plates are fixedly connected to the outer side of the inner housing, and multiple limiting posts are fixedly connected to the bottom of the inner housing. The multiple limiting posts are arranged in a rectangular array on the lower surface of the inner housing.
[0009] By adopting the above technical solution, multiple batteries can be independently positioned inside the inner casing, making battery replacement more convenient without causing significant movement to adjacent batteries, and allowing for quick installation after battery replacement.
[0010] As a further description of the above technical solution: an auxiliary installation mechanism is provided inside the outer casing. The auxiliary installation mechanism includes multiple connecting rods. The outer side of the connecting rods is fixedly connected to the inner wall of the outer casing. Two auxiliary wheels are rotatably connected to the outer side of the connecting rods. The two auxiliary wheels are evenly arranged on one side of the connecting rods.
[0011] By adopting the above technical solution, multiple auxiliary wheels can guide the four corners of the inner box, avoiding collisions between the inner box and the inner wall of the outer box during installation.
[0012] As a further description of the above technical solution: two guide plates are fixedly connected to the inner wall of the outer box, multiple bases are fixedly connected inside the outer box, a rubber pad is fixedly connected to the top of the base, multiple limiting rods are slidably connected to the outer side of the base, a spring is installed on the outer side of the limiting rod, and two arc-shaped clamping blocks are provided above the base, with one side of the arc-shaped clamping block fixedly connected to the two limiting rods.
[0013] By adopting the above technical solution, multiple limiting posts at the bottom of the inner box can be clamped and positioned, so that the inner box can maintain sufficient connection stability after being installed inside the outer box.
[0014] As a further description of the above technical solution: an outer cover is installed on the top of the outer casing, and two handles are hinged to the outside of the outer casing.
[0015] By adopting the above technical solution, the outer casing can be easily retrieved.
[0016] The technical effects and advantages of this utility model are as follows:
[0017] By setting up a battery positioning mechanism, multiple batteries can be clamped and positioned independently compared with existing technologies, which facilitates the quick separation of batteries from the inner casing. At the same time, only individual batteries need to be moved, avoiding shaking of healthy batteries and improving the efficiency of battery maintenance and replacement.
[0018] By setting up an auxiliary installation mechanism, compared with existing technologies, the process of the inner box entering the outer box is guided, so that the inner box can enter the interior of the outer box smoothly. At the same time, the inner box can maintain sufficient stability inside the outer box, preventing the inner box from becoming loose inside the outer box and improving the safety of the inner box in use.

[0026] 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.
[0027] This application discloses a quick-swap new energy battery vehicle housing, including an outer housing 1, an inner housing 2 inside the outer housing 1, and a battery positioning mechanism inside the inner housing 2. The battery positioning mechanism includes multiple first positioning plates 3, with both ends of the first positioning plates 3 fixedly connected to the inner wall of the inner housing 2. Two guide rods 5 are slidably connected inside the inner housing 2, and multiple second positioning plates 6 are fixedly connected inside each of the two guide rods 5. Multiple second buffer pads 7 are fixedly connected to one side of the second positioning plates 6, and pull rods 8 are fixedly connected to one side of the guide rods 5. Multiple gaskets 9 are installed inside the inner housing 2, and multiple limiting brackets 10 are fixedly connected to the inner wall of the inner housing 2. Pins 11 are inserted into the limiting brackets 10. Multiple batteries 12 are installed inside the inner box 2. Two pull plates 13 are fixedly connected to the outside of the inner box 2. Multiple limiting posts 14 are fixedly connected to the bottom of the inner box 2. The multiple limiting posts 14 are distributed in a rectangular array on the lower surface of the inner box 2. Pushing the two pull rods 8 causes the corresponding guide rods 5 to slide on the inner wall of the inner box 2. The two guide rods 5 cause multiple second positioning plates 6 to separate from multiple first buffer pads 4, so that multiple batteries 12 can be removed from the inside of the inner box 2. After the batteries 12 are replaced, the batteries 12 are put back into the corresponding second positioning plates 6 and first buffer pads 4. Then push the pull rods 8 to make the second positioning plates 6 and first buffer pads 4 clamp and fix the batteries 12 again.
[0028] Reference Figure 3 As shown, an auxiliary installation mechanism is provided inside the outer casing 1. The auxiliary installation mechanism includes multiple connecting rods 15. The outer side of the connecting rods 15 is fixedly connected to the inner wall of the outer casing 1. Two auxiliary wheels 16 are rotatably connected to the outer side of the connecting rods 15. The two auxiliary wheels 16 are evenly arranged on one side of the connecting rods 15. The multiple auxiliary wheels 16 can guide the outer side of the inner casing 2, so that the inner casing 2 can be accurately placed into the interior of the outer casing 1. At the same time, two pull plates 13 can engage with two guide plates 17, so that the inner casing 2 can be accurately placed into the interior of the outer casing 1.
[0029] Reference Figure 5 As shown, two guide plates 17 are fixedly connected to the inner wall of the outer casing 1, and multiple bases 18 are fixedly connected inside the outer casing 1. A rubber pad 19 is fixedly connected to the top of the base 18, and multiple limiting rods 20 are slidably connected to the outer side of the base 18. Springs 21 are installed on the outer side of the limiting rods 20. Two arc-shaped clamps 22 are set above the base 18. One side of the arc-shaped clamps 22 is fixedly connected to the two limiting rods 20. The corresponding multiple springs 21 push the limiting rods 20 and the arc-shaped clamps 22 to clamp the limiting post 14, so that the bottom of the inner casing 2 can be quickly connected to the inside of the outer casing 1.
[0030] Reference Figure 2As shown, an outer cover 23 is installed on the top of the outer box 1, and two handles 24 are hinged to the outside of the outer box 1 to provide some protection for the top of the inner box 2, while the outer box 1 can be taken out through the handles 24.
[0031] The working principle of this utility model is as follows: When repairing the new energy battery box, first remove the outer cover 23 from the top of the outer box 1, pull the two pull plates 13 to pull the inner box 2 out from the inside of the outer box 1, then pull out the corresponding pin 11 from the inside of the limiting frame 10, and pull the two pull rods 8 to the sides inside the corresponding two limiting frames 10. The two pull rods 8 drive the bottom guide rods 5 to slide in opposite directions on the inner wall of the inner box 2. The two guide rods 5 drive multiple guide rods 5 and the second positioning plate 6 to separate from the first positioning plate 3 and the first buffer pad 4, so that multiple batteries 12 are loosened and fixed inside the inner box 2. Individual batteries 12 can be taken out from the inside of the inner box 2 for quick replacement. Then, the replaced inner box 2 is put back into the corresponding second positioning plate 6 and the first buffer pad 4, so that the bottom of the battery 12 is cushioned by the pad 9. Then, push the two pull rods 8 to move in opposite directions, so that multiple second positioning plates 6 and the first buffer pad 4 can position the upper and lower sides of the battery 12.
[0032] Align the inner casing 2 with the opening of the outer casing 1. When the four corners of the inner casing 2 contact the multiple connecting rods 15 and auxiliary wheels 16 on the inner wall of the outer casing 1, the inner casing 2 can be smoothly placed into the outer casing 1. Then, when the multiple limiting posts 14 at the bottom of the inner casing 2 contact the multiple arc-shaped clamping blocks 22 inside the outer casing 1, press the inner casing 2 down so that the multiple limiting posts 14 squeeze the corresponding two arc-shaped clamping blocks 22. This causes the arc-shaped clamping blocks 22 to move to both sides through the two springs 21 and the limiting rods 20. Finally, the limiting posts 14 can be fixed inside the two arc-shaped clamping blocks 22. Then, put the outer casing cover 23 back on the top of the outer casing 1 to complete the installation of the new energy battery.

Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.
[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
