[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels but employ new onboard power devices), integrating advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles and new technologies and structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0003] Electric vehicles offer advantages such as low noise, high driving stability, and zero emissions, which are of positive significance for maintaining national energy security, reducing exhaust emissions, promoting the development of the automotive industry, and ultimately ensuring sustainable social development. As electric vehicles become more widespread, the energy density requirements for their battery systems are increasing.

[0004] Currently, the improvement of battery cell energy density has reached a bottleneck, making the reduction of power battery pack structure weight increasingly urgent, especially the weight reduction of module structure. In existing battery modules, steel or aluminum plates are used as structural components, which cannot effectively improve the battery pack. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a new energy vehicle battery module to solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A new energy vehicle battery module includes a base with a U-shaped structure, a plurality of mounting boxes on the base, and a battery pack disposed within each mounting box. The module also includes: The first mounting mechanism has a rotating shaft on one side of the base, the rotating shaft being located at the center of the base, the rotating shaft being connected to the first mounting mechanism via a support plate, the support plate being fixedly connected to one side of the first mounting mechanism, the rotating shaft driving the support plate to move up and down, and mounting boxes being provided on both sides of the first mounting mechanism, the first mounting mechanism being fixedly connected to the mounting boxes; A second mounting mechanism is movably connected to the first mounting mechanism, and mounting boxes are provided on both sides of the second mounting mechanism, with the second mounting mechanism fixedly connected to the mounting boxes; and A third installation mechanism is movably connected to the second installation mechanism, and installation boxes are provided on both sides of the third installation mechanism, with the third installation mechanism fixedly connected to the installation boxes.

[0009] As a further embodiment of the present invention, the third mounting mechanism includes: A third mounting bracket, wherein the third mounting bracket is disposed within the second mounting bracket, and the third mounting bracket is fixedly connected to the mounting box; and The third rack is fixedly connected to the third mounting base on one side, and the third rack is movably connected to the second gear.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0022] In one embodiment, a new energy vehicle battery module, see [link / reference] Figures 1-4 The system includes a base 1, which has a U-shaped structure, and several mounting boxes 3 are provided on the base 1. Each mounting box 3 contains a battery pack 2. The system also includes: The first mounting mechanism 5 has a rotating shaft 4 on one side of the base 1, the rotating shaft 4 is located at the center of the base 1, the rotating shaft 4 is connected to the first mounting mechanism 5 through a support plate 13, the support plate 13 is fixedly connected to one side of the first mounting mechanism 5, the rotating shaft 4 drives the support plate 13 to move up and down, and mounting boxes 3 are provided on both sides of the first mounting mechanism 5, the first mounting mechanism 5 is fixedly connected to the mounting boxes 3; A second mounting mechanism 6 is movably connected to the first mounting mechanism 5. Mounting boxes 3 are provided on both sides of the second mounting mechanism 6, and the second mounting mechanism 6 is fixedly connected to the mounting boxes 3. The third mounting mechanism 7 is movably connected to the second mounting mechanism 6. Mounting boxes 3 are provided on both sides of the third mounting mechanism 7, and the third mounting mechanism 7 is fixedly connected to the mounting boxes 3.

[0023] In this embodiment, by setting multiple symmetrical mounting boxes 3 and placing the battery pack 2 inside the mounting boxes 3, the range of the new energy vehicle can be increased, and the actual usage time can be improved. At the same time, the mounting boxes 3 are made of perforated material, which can dissipate heat from the battery pack 2 when it is working, thereby protecting the battery pack 2. Meanwhile, the rotation of the rotating shaft 4 drives the support plate 13 to move upward, the support plate 13 drives the first mounting mechanism 5 to move upward, the first mounting mechanism 5 drives the second mounting mechanism 6 to move upward, and the second mounting mechanism 6 drives the third mounting mechanism 7 to move upward. By setting the size of the gear rack teeth, the upward movement is not uniform, which makes it easier to pick up and install the battery pack 2. At the same time, the battery pack 2 can be divided into three batches, which better protects the battery pack 2 inside.

[0024] In one embodiment, see Figures 1-4 The first installation mechanism 5 includes: A first rack 51 is fixedly connected to the inner wall of the base 1, and the first rack 51 is symmetrically arranged about the base 1. A first mounting base 53 is disposed on one side of the first rack 51. A first gear 52 is disposed inside the first mounting base 53 and is movably connected to the first mounting base 53. The support plate 13 is fixedly connected to the bottom of the first mounting base 53, and the mounting box 3 is fixedly connected to the first mounting base 53. The second rack 54 is fixedly connected to the first mounting base 53 and movably connected to the second mounting mechanism 6.

[0025] Further, see Figures 1-4 The second installation mechanism 6 includes: A second rack 61 is movably connected to the first gear 52. The second rack 61 is disposed on one side of a second mounting base 63, which is disposed within the first mounting base 53 and is fixedly connected to the mounting box 3. The second gear 62 is disposed in the second mounting base 63, and is movably connected to the second rack 54 and the third mounting mechanism 7.

[0026] Further, see Figures 1-4 The third installation mechanism 7 includes: A third mounting base 71 is disposed within the second mounting base 63, and the third mounting base 71 is fixedly connected to the mounting box 3; and The third rack 72 is fixedly connected to the third mounting base 71 on one side, and the third rack 72 is movably connected to the second gear 62.

[0027] In this embodiment, the rotation of the rotating shaft 4 causes the support plate 13 to move upward, the support plate 13 causes the first mounting base 53 to move upward, the first gear 52 provided in the first mounting base 53 rotates, the first gear 52 is limited and guided by the first rack 51, so that the first gear 52 moves up and down, and at the same time the first gear 52 drives the second rack 61, and the second mounting base 63 moves upward by the first gear 52 pushing the second rack 61. At the same time, the second gear 62 inside the second mounting base 63 rotates. Under the action of the second rack 54, the second gear 62 is limited and guided, causing the second gear 62 to move up and down. The second gear 62 drives the third rack 72, and the third mounting base 71 moves upward by the second gear 62 moving the third rack 72. The first mounting base 53, the second mounting base 63, and the third mounting base 71 move the mounting box 3 upwards, and the upward movement is not the same. The third mounting base 71 moves upwards the most. In the event of an impact, the battery pack 2 inside can be better protected, allowing the new energy vehicle to drive to the emergency lane and better protect the driver and other road users.

[0028] In one embodiment, see Figures 1-4 The base 1 has a first card plate 11 and a second card plate 12 on its outer side. The first card plate 11 is movably connected to the second card plate 12. A fixing block 10 is provided on one side of the second card plate 12. The fixing block 10 is connected to the second card plate 12 through a second energy absorption mechanism 9. The fixing block 10 is connected to the first card plate 11 through a first energy absorption mechanism 8.

[0029] Further, see Figures 1-4 The first energy-absorbing mechanism 8 includes: A first mounting block 81 is movably connected to the fixed block 10, and one end of the first mounting block 81 is fixedly connected to a first elastic element 82; and The second mounting block 83 is fixedly connected to the other end of the first elastic member 82, and the second mounting block 83 is movably connected to the first card plate 11.

[0030] Further, see Figures 1-4 The second energy-absorbing mechanism 9 includes: The third mounting block 91 is movably connected to the fixed block 10 and is fixedly connected to the mounting rod 92; A second elastic element 93 is disposed on one side of the mounting rod 92; and The fourth mounting block 94 is fixedly connected to the mounting rod 92, and the fourth mounting block 94 is movably connected to the second clamping plate 12.

[0031] In this embodiment, one side of the first card plate 11 and the second card plate 12 are fixed around the base 1, while the other side of the first card plate 11 and the second card plate 12 are installed inside the new energy vehicle. When the new energy vehicle is hit, the vehicle body will shake, and the vehicle body will cause the first card plate 11 and the second card plate 12 to shake. The four legs of the first card plate 11 and the second card plate 12 are all movable connections. At the same time, the second card plate 12 drives the first mounting block 81 and the third mounting block 91 to move through the fixing block 10. The first mounting block 81 drives the second mounting block 83 through the first elastic element 82. The second mounting block 83 drives the first card plate 11 to move. The third mounting block 91 drives the fourth mounting block 94 to move through the second elastic element 93 on the mounting rod 92. The fourth mounting block 94 drives the second card plate 12 to move, thereby reducing the impact force from the vehicle body to the battery pack 2.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
