[0017] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1 to 5 This utility model provides a technical solution: Example 1: A battery pack installation mechanism for a new energy vehicle includes: a vehicle floor plate 1 and a positioning post 5.

[0019] Specifically, two parallel crossbeams 2 are fixedly installed on the lower surface of the vehicle floor 1. Hooks 3 are rotatably mounted at both ends of the crossbeams 2, and the hooks 3 are vertically positioned under gravity. The hooks 3 are J-shaped and rotate only in the vertical plane containing the crossbeams 2. That is, when the hooks 3 rotate upwards, they can approach the crossbeams 2. A battery pack body 4 is located below the vehicle floor 1. Lifting lugs 41 are fixed to both sides of the battery pack body 4, and the four lugs 41 are suspended from the lower ends of the hooks 3. When the battery pack body 4 is lifted... First, lift one end and suspend the two lugs 41 of one end on the two hooks 3 at the corresponding positions. Then lift the other end and suspend the two lugs 41 of the other end on the other two hooks 3. At this time, the battery pack body 4 can be suspended horizontally directly below the vehicle floor 1. The gap between the battery pack body 4 and the vehicle floor 1 is small. By horizontally pushing the battery pack body 4 and driving the hooks 3 to rotate, the battery pack body 4 can move upward while moving horizontally, which makes it easier to fix the battery pack body 4 to the lower surface of the vehicle floor 1. Secondly, the positioning post 5 is installed on the lower surface of the vehicle floor 1 and located on the outer side of one end of the battery pack body 4. An X-shaped frame 6 is rotatably installed on the outer side of the positioning post 5. The X-shaped frame 6 can be folded or unfolded. When the X-shaped frame 6 is unfolded, it can push the battery pack body 4 to move in the horizontal direction. Flanges 42 are fixed on both sides of the battery pack body 4. The surface of the crossbeam 2 is provided with positioning screw holes 22 for bolts to pass through. The flanges 42 are fixedly connected to the crossbeam 2 by bolts. After the X-shaped frame 6 is unfolded and pushes the battery pack body 4 to a suitable position, the flanges 42 and the crossbeam 2 can be fixedly connected by bolts to ensure that the battery pack body 4 is stably installed on the lower surface of the vehicle floor 1.

[0020] To accommodate the hook 3 inside the crossbeam 2, this application also includes a storage groove 21 formed on the surface of the crossbeam 2. After the hook 3 is rotated to a horizontal position, it is stored within the cavity of the storage groove 21. Figure 2 and Figure 3 As shown, the storage slot 21 is designed to prevent collisions between the hook 3 and the crossbeam 2, which would affect the upward movement of the battery pack body 4.

[0021] In order to install the X-frame 6, the X-frame 6 of this application includes two intersecting movable plates 61 forming an "X" shape. The middle of each movable plate 61 is provided with a through hole 62 for the positioning post 5 to pass through. That is to say, after the X-frame 6 and the positioning post 5 are installed, the horizontal position of the X-frame 6 can be fixed. When the X-frame 6 is rotated and unfolded, it can push the battery pack body 4 to move horizontally. Since the battery pack body 4 is suspended on the hook 3 under the action of gravity, when the battery pack body 4 moves horizontally, the hook 3 will rotate accordingly and drive the battery pack body 4 to move upward and closer to the vehicle floor 1.

[0022] To prevent the X-frame 6 from detaching from the positioning post 5, this application also includes an anti-detachment platform 55 fixed at the lower end of the outer side wall of the positioning post 5. The inner wall of the through hole 62 is provided with a relief groove 63 that matches the anti-detachment platform 55. When the two movable plates 61 are folded together so that the two relief grooves 63 correspond, the positioning post 5 can pass through the through hole 62 of the X-frame 6. When the anti-detachment platform 55 below the positioning post 5 completely passes through the through hole 62 to the bottom of the X-frame 6, the two movable plates 61 can be unfolded. When the two movable plates 61 are unfolded together, the two relief grooves 63 will be misaligned. At this time, the anti-detachment platform 55 and the relief groove 63 are misaligned, and the X-frame 6 will not separate from the positioning post 5 due to its own weight.

[0023] To facilitate the unfolding of the X-frame 6, this application also includes a torsion spring 64 fixedly installed between the two movable plates 61. A gap is left between the end of the two movable plates 61 near the battery pack body 4 and the battery pack body 4. A handle 65 is fixedly installed at the end of the two movable plates 61 away from the battery pack body 4. After the worker suspends the X-frame 6 on the positioning column 5, the X-frame 6 can be unfolded as a whole and the battery pack body 4 can be moved by pulling the two handles 65 closer together.

[0024] In order to store the positioning post 5, this application also has a storage tube 51 sleeved on the outer side of the upper end of the positioning post 5, and the storage tube 51 is fixed to the lower surface of the vehicle floor plate 1. The positioning post 5 can move in the vertical direction so as to be stored in the inner cavity of the storage tube 51.

[0025] To prevent the positioning post 5 from easily extending out of the inner cavity of the storage tube 51, this application also has a limiting protrusion 53 fixed on the upper end of the outer side wall of the positioning post 5. The inner side wall of the storage tube 51 is provided with a limiting groove 52 for the limiting protrusion 53 to slide. The limiting groove 52 is "T" shaped on the inner wall of the storage tube 51. When the positioning post 5 moves upward and drives the limiting protrusion 53 to move upward, the positioning post 5 can rotate and lock the limiting protrusion 53 into the horizontal groove at the top of the limiting groove 52. At this time, the positioning post 5 is retracted into the inner cavity of the storage tube 51 and will not fall due to gravity. Conversely, when the limiting protrusion 53 corresponds to the vertical groove of the limiting groove 52, the positioning post 5 can move downward and extend out of the inner cavity of the storage tube 51.

[0026] To maintain the stability of the positioning post 5 when it extends out of the inner cavity of the storage tube 51, this application also includes a thrust spring 54 installed in the inner cavity of the storage tube 51. The lower end of the thrust spring 54 presses against the upper end face of the positioning post 5. The thrust spring 54 is always in a compressed state. When the positioning post 5 extends out of the inner cavity of the storage tube 51, the thrust spring 54 generates a downward thrust on the positioning post 5, so that the X-shaped frame 6 can be sleeved on the outside of the positioning post 5 from bottom to top.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
