[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0027] Embodiment 1, as Figures 1-4As shown in the figure, the utility model provides a module bracket for a new energy vehicle battery, which includes a battery module 1. A bottom plate 2 is fixedly connected to the bottom of the battery module 1. First sliding grooves 21 are formed on the four sides of the top surface of the bottom plate 2. Lifting mechanisms 4 are movably connected to the four sides of the top end of the bottom plate 2. The lifting mechanism 4 includes a support frame 41. Adjusting mechanisms 3 are arranged on both sides of the four sides of the bottom plate 2. The adjusting mechanism 3 includes a first sliding component 31, a second sliding component 32 and a rotating component 33. The first sliding component 31 includes a sliding outer tube 311. A sliding inner rod 321 is slidably connected to the inside of the sliding outer tube 311. The rotating component 33 includes two rotating seats 333. One of the rotating seats 333 is fixedly connected to the side wall of the support frame 41, and the other rotating seat 333 is fixedly connected to the outer side wall of the first rotating rod 331. A first rotating rod 331 is movably connected between the two rotating seats 333. The sliding inner rod 321 is fixedly connected to the bottom plate 2. By pushing the sliding outer tubes 311 around inward, the rotating seats 333 on the sliding outer tubes 311 approach the bottom plate 2. Since the length of the first rotating rod 331 remains unchanged, the rotating seat 333 at the top end of the first rotating rod 331 drives the support frame 41 to move downward, and the adjusting mechanisms 3 around are respectively pushed to the same position, so that the four support frames 41 slide to the top and always remain in the same horizontal plane.

[0028] As Figure 4 shown, rotating holes 332 are formed at both ends of the first rotating rod 331. A rotating shaft is fixedly connected to the inside of the rotating seat 333. The first rotating rod 331 is rotatably connected to the rotating seat 333 through the rotating shaft. The two ends of the first rotating rod 331 are respectively rotated with the rotating seat 333 through the rotating shaft. By pushing the sliding outer tube 311, different included angles between the first rotating rod 331 and the sliding outer tube 311 can be adjusted, and the rising heights of the corresponding support frames 41 are also different.

[0029] As Figure 1 and Figure 2 shown, second sliding grooves 43 are formed on the bottom surface of the support frame 41. Two second rotating rods 42 are movably connected between the support frame 41 and the bottom plate 2 through the first sliding grooves 21 and the second sliding grooves 43. The second rotating rods 42 play an auxiliary role in adjusting the height of the support frame 41. At the same time, the second rotating rods 42 around the bottom plate 2 can also ensure the sealing performance of the bottom plate 2 for the battery module 1. The second rotating rods 42 also play a supporting role for the support frame 41.

[0030] As Figure 3As shown in the figure, a plurality of limiting holes 312 are evenly formed in the outer side wall of the sliding outer tube 311. One end of the sliding outer tube 311 away from the bottom plate 2 is fixedly connected with a handle 313. The sliding inner rod 321 is limited through the limiting holes 312, so that the height of the support frame 41 can be kept stable, avoiding the problem that the sliding inner rod 321 slides on the sliding outer tube 311. Installing the handle 313 makes the adjustment of the sliding outer tube 311 more labor-saving.

[0031] As Figure 4 shown in the figure, a limiting block 322 is arranged at the top of one end of the sliding inner rod 321 away from the bottom plate 2. A spring 323 is fixedly connected between the bottom end of the limiting block 322 and the outer side wall of the sliding inner rod 321. When it is necessary to fix the sliding outer tube 311, only need to slide the limiting block 322 on the sliding inner rod 321 into a certain limiting hole 312. At this time, the spring 323 limits the limiting block 322 on the limiting hole 312. When it is necessary to move the sliding outer tube 311 again, press the limiting block 322 into the limiting hole 312, and then it can slide again.

[0032] As Figure 1 shown in the figure, magnets are fixedly connected to both ends of the support frame 41. Lubricants are applied inside the first sliding groove 21 and the second sliding groove 43, maintaining the stability of the four support frames 41, making the structure of the support frame 41 more firm, and applying lubricants is convenient for the sliding of the second rotating rod 42.

[0033] As Figure 1 shown in the figure, the length of the first rotating rod 331 is 1.5 times the length of the second rotating rod 42. A sponge foam is laid on the inner side wall of the bottom plate 2. The battery module 1 can be protected through the sponge foam, avoiding damage to the battery module 1 and increasing the service life of the battery module 1.

[0034] The using method and working principle of the device: Press the limiting block 322 into the limiting hole 312, pull the surrounding sliding outer tubes 311 outwards. The first rotating rod 331 drives the rotating seat 333 at the top to slide downwards, and the support frame 41 moves downwards. Reposition the limiting block 322 with the corresponding limiting hole 312 again, and the spring 323 limits the limiting block 322 on the limiting hole 312. Place the battery module 1 from the chassis to the vehicle battery installation hole. Press the limiting block 322 again, push the sliding outer tube 311 inwards, the first rotating rod 331 drives the support frame 41 to move upwards, limit the position of the limiting block 322, and lead out the incoming line of the battery module 1 from the bottom of the lifting mechanism, and realize the installation and fixation of the battery module 1.

[0035] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
