DETAILED DESCRIPTION

[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 utility model provides an embodiment: a new energy battery anti-collision frame, comprising a protective frame 1, a top cover 2 is installed on the top of the protective frame 1 by bolts, a bottom protective plate 3 is installed on the bottom of the protective frame 1 by bolts, two groups of V-shaped rods 12 and cross bars 13 are embedded in the interiors of the top cover 2 and the bottom protective plate 3, the cross bars 13 are embedded in the middle of the V-shaped rods 12, and a second partition 14 is embedded in the interiors of the top cover 2 and the bottom protective plate 3. The two groups of second partitions 14 are respectively located above and below the protective frame 1, and a through hole 15 is opened in the interior of the second partition 14. A heat dissipation hole 5 is opened on the top of the top cover 2, and a heat dissipation hole 2 16 is opened on the bottom of the bottom protective plate 3;

[0024] The protective frame 1 and the top cover 2 as well as the protective frame 1 and the bottom protective plate 3 are fixed by bolts. The top cover 2 and the bottom protective plate 3 are installed with V-shaped rods 12 and cross bars 13 inside by welding, and the cross bars 13 run through the middle of the V-shaped rods 12. The cross bars 13 are used to reinforce the firmness of the protection of the V-shaped rods 12. The V-shaped rods 12 are V-shaped, which increases the area of the gap while providing protection, so as to facilitate subsequent effective heat dissipation. The partition 14 is installed in the top cover 2 and the bottom protective plate 3 by welding to provide a flat support platform for the battery pack. At the same time, the through hole 15 can effectively dissipate the heat on the battery pack, thereby realizing the heat dissipation function. When the vehicle collides with a larger vehicle head-on, the battery anti-collision frame The frame will be squeezed from above. When the collision force exceeds the preset value, the top cover 2 will be deformed. The internal V-shaped rod 12 and cross bar 13 will disperse the collision force from the collision point, reducing the accumulation of collision force, thereby avoiding direct squeezing of the battery pack by the top cover 2 during a collision, causing serious damage. In addition, when the vehicle chassis contacts a protrusion on the ground, the bottom protective plate 3 is reinforced by the V-shaped rod 12 and cross bar 13 to reduce the impact of the bottom protective plate 3 on the bottom of the battery pack. By protecting the bottom and top of the battery pack, the safety of the battery pack is improved to a certain extent. While ensuring the safety of the battery pack, the heat dissipation efficiency is effectively improved, and the heat concentration of the battery pack is reduced to a certain extent.

[0025] The outer walls of both sides of the protective frame 1 are embedded with inverted V-shaped oblique rods 10, the front wall and the back wall of the protective frame 1 are embedded with X-shaped oblique rods 9 and vertical rods, the inner walls of the protective frame 1 are installed with inner protective plates 11, the outer walls of the protective frame 1 are installed with outer protective plates 6, the inner parts of the outer protective plates 6 are provided with heat dissipation side holes 4, and the inner parts of the inner protective plates 11 are provided with holes, which correspond to the positions of the heat dissipation side holes 4;

[0026] The inverted V-shaped diagonal rod 10, the X-shaped diagonal rod 9 and the vertical rod are installed inside the protective frame 1 by welding. In addition, the inner protective plate 11 is installed on the inner wall of the protective frame 1 by welding. The X-shaped diagonal rod 9 and the inverted V-shaped diagonal rod 10 improve the protection of the protective frame 1 while ensuring firm support, and there is more space for heat dissipation. When the vehicle is subjected to a huge collision from the side, the heat dissipation side hole 4 will be deformed, and the X-shaped diagonal rod 9 and the inverted V-shaped diagonal rod 10 in the protective frame 1 will disperse the collision force, thereby improving the protection performance of the battery pack by dispersing the collision force. When the vehicle is driving normally, the heat generated by the battery pack will be dissipated from the protective frame 1 through the holes on the inner protective plate 11, the gap between the X-shaped diagonal rod 9 and the inverted V-shaped diagonal rod 10, and the heat dissipation side hole 4 on the outer protective plate 6, so that heat can be dissipated on the basis of comprehensive protection, reducing heat accumulation in the battery pack, and thus extending the service life of the battery pack.

[0027] A partition 8 is installed inside the protective frame 1. The partition 8 is used to isolate the battery pack. Protective films are installed on both sides of the partition 8. The front and back walls of the partition 8 are installed with bumps. A groove 7 is opened on the top of the protective frame 1, and the groove 7 corresponds to the position of the partition 8.

[0028] The protective film is made of insulating and heat-insulating materials, which effectively prevents the battery packs on both sides of the partition 8 from being squeezed against each other due to collision, thereby causing short circuit and damage to the battery pack. In addition, the position of the partition 8 can be adjusted according to actual usage requirements. It is only necessary to insert the partition 8 into the protective frame 1 and let the protrusions on the partition 8 be embedded in the corresponding grooves 7, which is convenient for installation and disassembly.

[0029] Working principle: Install the protective frame 1 on the bottom protective plate 3 with bolts, then insert the partition 8 into the protective frame 1 according to the width of the battery pack, and let the protrusion on the partition 8 enter the groove 7, then put the battery pack into the protective frame 1, and use bolts to fix the top cover 2 and the protective frame 1, and finally fix the entire battery anti-collision frame to the corresponding position of the vehicle with bolts. When the vehicle collides head-on with a larger vehicle, the battery anti-collision frame will be squeezed from above. When the collision force exceeds the preset value, the top cover 2 will be deformed, and the internal V-bar 12 and cross bar 13 will disperse the collision force from the collision point, reducing the accumulation of collision force, thereby avoiding direct squeezing of the battery pack by the top cover 2 during a collision, and effectively improving the heat dissipation efficiency while ensuring the safety of the battery pack, reducing the heat concentration of the battery pack 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.
