[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0023] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The present utility model provides an embodiment: a new energy battery frame with an anti-collision structure, comprising a frame 1, a bottom plate 3 being mounted on the bottom of the frame 1 by bolts, cross bars 10 being evenly arranged inside the bottom plate 3, an X-shaped bar 11 being mounted between two groups of cross bars 10, a partition 9 being embedded in the top of the bottom plate 3, the partition 9 being located above the cross bars 10, a hole 17 being formed on the top of the partition 9, and a hole 16 being formed on the bottom of the bottom plate 3;

[0024] The frame 1 and the bottom plate 3 are fixed by bolts. The inside of the bottom plate 3 is welded with a cross bar 10 and an X-shaped bar 11. The X-shaped bar 11 is X-shaped and has better protection. The partition 9 is welded to the inside of the bottom plate 3. When the entire battery frame is hit, if the collision force exceeds the maximum preset value that the battery frame can withstand, the frame 1 and the bottom plate 3 will be deformed. Usually, the bottom plate 3 is the weakest part of the protection. With the reinforcement of the cross bar 10 and the X-shaped bar 11, the protection of the battery pack 13 is increased. The collision force will be transmitted to the cross bar 1 0 and X-shaped rod 11, the cross bar 10 and the X-shaped rod 11 disperse the force on the collision point to reduce the direct damage of the collision force to the battery pack 13, avoid the squeezing of the battery pack 13 due to the deformation of the bottom plate 3, and improve the protection of the bottom to a certain extent, thereby improving the safety of the new energy battery. At the same time, since the partition 9 is provided with a hole 2 17, the bottom plate 3 is provided with a hole 16, and there is a gap between the cross bar 10 and the X-shaped rod 11, heat can be dissipated to a certain extent, reducing the accumulation of heat in the battery.

[0025] The inner wall of the frame 1 is installed with an inner plate 14, and the outer surface of the inner plate 14 is installed with a protective frame 15. The protective frame 15 includes two N-shaped diagonal bars 8 and a vertical bar 2 6 embedded in the front and back of the frame 1. The vertical bar 2 6 is located between the two groups of N-shaped diagonal bars 8. Two groups of vertical bars 1 5 and an inverted V-shaped diagonal bar 7 are embedded on both sides of the frame 1. The inverted V-shaped diagonal bar 7 is located between the two groups of vertical bars 1 5.

[0026] The inner wall of the frame 1 is welded with an inner plate 14, which is made of a composite material, and this composite material has the advantages of good insulation performance, corrosion resistance, electrical insulation, sufficient mechanical strength and light weight. A protective frame 15 is welded inside the frame 1, and the protective frame 15 includes an N-shaped oblique rod 8, a vertical rod 2 6, a vertical rod 1 5 and an inverted V-shaped oblique rod 7, and the vertical rod 1 5 and the inverted V-shaped oblique rod 7 are located on both sides of the frame 1, the vertical rod 2 6 and the N-shaped oblique rod 8 are located at the front and rear of the frame 1, the N-shaped oblique rod 8 provides good stability, and the inverted V-shaped oblique rod 7 is in an inverted V shape, which improves the stability and protection performance of the frame 1 to a certain extent. The vertical bar 1 5, the inverted V-shaped oblique bar 7, the vertical bar 2 6 and the N-shaped oblique bar 8 provide good support for the frame 1 while also increasing the protection performance of the frame 1. When the battery frame is hit from the side, the vertical bar 1 5, the vertical bar 2 6, the inverted V-shaped oblique bar 7 and the N-shaped oblique bar 8 will disperse the collision force on the frame 1 to reduce the concentration of force, thereby reducing the squeezing damage of the battery on the side of the frame 1, and protecting the battery from damage due to side collisions to a certain extent.

[0027] Two battery packs 13 and a second partition 12 are installed inside the frame 1. The second partition 12 is located between the two battery packs 13. A cover plate 2 is fixed to the top of the frame 1 by bolts. Threaded holes are evenly opened on the bottom of the bottom plate 3. An outer plate 4 is installed on the outer surface of the protective frame 15.

[0028] Partition 2 12 and the inner plate 14 are made of the same composite material. Partition 2 12 is mainly used to prevent collision between the two battery packs 13 in the event of a collision, which may cause a short circuit and ultimately damage the battery pack 13. The threaded holes on the bottom plate 3 are used to fix the entire battery frame inside the vehicle to facilitate the installation and disassembly of the battery frame. Since the frame 1 and the cover plate 2 as well as the frame 1 and the bottom plate 3 are fixed by bolts, the entire battery frame is easy to install and disassemble. When in use, first fix the bottom plate 3 to the frame 1, then place the battery pack 13 in the frame 1, and then fix the cover plate 2 to the top of the frame 1 with bolts to complete the seal, and finally fix the entire battery frame to the vehicle with bolts.

[0029] Working principle: When in use, first fix the bottom plate 3 to the frame 1, then place the battery pack 13 in the frame 1, and then fix the cover plate 2 to the top of the frame 1 with bolts to complete the seal, and finally fix the entire battery frame to the interior of the vehicle with bolts. When the entire battery frame is collided, if the collision force exceeds the maximum preset value that the battery frame can withstand, the frame 1 and the bottom plate 3 will be deformed. The cross bar 10 and the X-shaped bar 11 disperse the force at the collision point to reduce the direct damage of the collision force to the battery pack 13, avoid the extrusion of the battery pack 13 due to the deformation of the bottom plate 3, and improve the protection of the bottom to a certain extent.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention, and any reference numerals in the claims should not be construed as limiting the claims to which they relate.
