Description

A collision protection structure for new energy battery packs Technical Field

[0001] This utility model relates to the field of new energy battery technology, specifically a collision protection structure for a new energy battery pack. Background Technology

[0002] With the gradual upgrading of domestic automobile consumption, the research and development of new energy vehicles has received strong support from national policies. Due to the special structure of new energy batteries, the battery pack of new energy vehicles is generally located at the bottom of the vehicle. When the vehicle is driving on uneven roads, the bottom of the battery pack is easily scratched and collided by the ground protrusions, which may cause safety risks and affect the life safety of the driver and passengers. Therefore, it is necessary to use collision protection devices to protect the bottom of the battery pack.

[0003] However, existing collision protection devices usually involve adding chassis armor or protective plates to the bottom of the battery pack. When the bottom of the vehicle scrapes against a protrusion on the ground and the impact force on the bottom of the battery pack is large, the chassis armor or protective plates alone are insufficient to effectively buffer and weaken the impact force, resulting in poor protection and easy damage to the battery pack. This can lead to thermal runaway of the battery pack, causing personal injury and other economic losses. Summary of the Invention

[0004] The purpose of this utility model is to provide a collision protection structure for a new energy battery pack. Through the structural design of anti-collision plate, upright and spring, the impact force on the battery pack can be effectively buffered and weakened, solving the problem of difficulty in effectively buffering and weakening impact force.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a collision protection structure for a new energy battery pack, including a mounting base and a crash plate. The mounting base is provided with four fixing rings. The upper surface of the crash plate is vertically provided with four uprights. The outer surface of the uprights is fitted with a spring. The outer surface of the top of the uprights is fitted with the inner ring of the fixing rings. The lower surface of the crash plate is provided with an arc-shaped energy-absorbing plate, and the arc-shaped energy-absorbing plate has a honeycomb structure inside.

[0007] Furthermore, four stabilizer bars are vertically installed on the anti-collision plate, and four through holes are opened on the mounting base. The outer surface of the top of the stabilizer bar mates with the inner ring of the through hole.

[0008] Furthermore, a connecting block is provided on one side of the fixing ring, one end of the connecting block is connected to the surface of the mounting base, a limit plate one is provided at the top of the upright, and a limit plate two is provided at the top of the stabilizer.

[0009] Furthermore, the mounting base has a receiving groove, in which a battery pack fits, and the mounting base is provided with mounting buckles, the number of which is two pairs.

[0010] Furthermore, the mounting base is equipped with four locking components, each including a vertical plate. One side of the vertical plate has a rectangular groove with a circular groove inside. A slot is also provided on the vertical plate, which communicates with the circular groove and the rectangular groove. A fixing rod is vertically installed in the circular groove. A spring is fitted on the surface of the fixing rod. A movable sleeve is fitted on the outer surface of the bottom end of the fixing rod. The movable sleeve engages with the circular groove. A locking block is provided on one side of the movable sleeve. The locking block engages with the rectangular groove, and the bottom of the locking block contacts the upper surface of the battery pack.

[0011] Furthermore, the upright plate has a threaded hole that communicates with a rectangular groove. A fastening bolt is fitted inside the threaded hole. The locking block has a positioning groove, and one end of the fastening bolt engages with the positioning groove.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through the structural design of the anti-collision plate, upright, and springs, absorbs part of the impact energy through the deformation of the honeycomb mechanism inside the arc-shaped energy-absorbing plate, and absorbs the kinetic energy transmitted by the anti-collision plate through the compression of the four springs. This buffers and weakens the impact on the battery pack to a safe range, effectively protecting the battery pack on the mounting base. This effectively buffers and weakens the impact force on the battery pack, improves the protection effect of the battery pack, avoids thermal runaway caused by battery pack damage, reduces personal injury and other economic losses.

[0014] 2. This utility model, through the structural design of the locking component, allows the fastening bolt to rotate within the threaded hole and enter the rectangular groove by rotating the fastening bolt. This causes one end of the fastening bolt to engage with the positioning groove on the locking block, thereby effectively fixing the battery pack with four locking blocks. This prevents the battery pack from shifting due to vibration, effectively limiting and fixing the battery pack, improving its stability, preventing short circuits between cells, and effectively enhancing the protection of the battery pack.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4. This utility model provides a technical solution: a collision protection structure for a new energy battery pack, including a mounting base 1 and a crash plate 2. The mounting base 1 is provided with four fixing rings 101. The mounting base 1 has a receiving groove, in which a battery pack 7 is fitted. The mounting base 1 is provided with two pairs of mounting buckles 103, which can facilitate the installation of the battery pack 7 at the bottom of the vehicle.

[0023] Four uprights 3 are vertically arranged on the upper surface of the anti-collision plate 2. The outer surface of the uprights 3 is fitted with a spring 4. The outer surface of the top of the uprights 3 is fitted with the inner ring of the fixing ring 101. A connecting block is provided on one side of the fixing ring 101. One end of the connecting block is connected to the surface of the mounting base 1, which can facilitate the connection between the fixing ring 101 and the mounting base 1. An arc-shaped energy-absorbing plate 201 is provided on the lower surface of the anti-collision plate 2. The arc-shaped energy-absorbing plate 201 has a honeycomb structure inside. Four stabilizing rods 5 are vertically arranged on the anti-collision plate 2. Four through holes 102 are opened on the mounting base 1. The outer surface of the top of the stabilizing rod 5 is fitted with the inner ring of the through hole 102, which can ensure that the anti-collision plate 2 can retract stably after being impacted. A limit piece 1 is provided at the top of the uprights 3 to prevent the uprights 3 from sliding out of the fixing ring 101. A limit piece 2 is provided at the top of the stabilizing rods 5 to limit the stabilizing rods 5.

[0024] When a new energy vehicle is driving on an uneven road surface, and the vehicle chassis scrapes and collides with a road bump, the bump impacts the arc-shaped energy-absorbing plate 201 at the bottom of the anti-collision plate 2. After being impacted, the honeycomb structure inside the arc-shaped energy-absorbing plate 201 deforms and absorbs part of the impact energy. The remaining kinetic energy is compressed against the anti-collision plate 2 by the arc-shaped energy-absorbing plate 201. The impact force causes the anti-collision plate 2 to move upward, causing the four uprights 3 on the anti-collision plate 2 to slide upward within the corresponding fixing rings 101 and compress the springs 4 on the surface of the uprights 3. The springs 4 contract after being compressed. The compression of the four springs 4 absorbs the kinetic energy transmitted by the anti-collision plate 2, and the impact on the battery pack 7 is buffered and weakened to a safe range, thus achieving effective protection for the battery pack 7 on the mounting base 1.

[0025] The mounting base 1 is provided with four locking components 6. Each locking component 6 includes a vertical plate 601. A rectangular groove 6012 is formed on one side of the vertical plate 601, and a circular groove 6011 is formed inside the rectangular groove 6012. A slot 6013 is formed on the vertical plate 601, which communicates with the circular groove 6011 and the rectangular groove 6012. A fixing rod 602 is vertically arranged inside the circular groove 6011. A spring 603 fits on the surface of the fixing rod 602. A movable sleeve 604 fits on the outer surface of the bottom end of the fixing rod 602. 04 mates with the circular groove 6011. A locking block 605 is provided on one side of the movable sleeve 604. The locking block 605 mates with the rectangular groove 6012. The bottom of the locking block 605 contacts the upper surface of the battery pack 7. A threaded hole 6014 is provided on the upright plate 601. The threaded hole 6014 communicates with the rectangular groove 6012. A fastening bolt 606 is fitted in the threaded hole 6014. A positioning groove is provided on the locking block 605. One end of the fastening bolt 606 mates with the positioning groove, which can lock the movable sleeve 604.

[0026] After placing the battery pack 7 into the receiving slot on the mounting base 1, rotate the locking blocks 605 on the four locking parts 6 by 90 degrees respectively, so that the locking blocks 605 are rotated out of the slots 6013, making the locking blocks 605 engage with the rectangular slots 6012. After rotating the locking blocks 605 out of the slots 6013 and into the rectangular slots 6012, the compressive force of the movable sleeve 604 on the second spring 603 disappears, and the second spring 603 rebounds on the surface of the fixed rod 602, pressing the locking blocks 605 downward through the movable sleeve 604, so that the locking blocks The bottom of 605 is in close contact with the upper surface of the battery pack 7. Then, the fastening bolt 606 is rotated so that the fastening bolt 606 rotates in the threaded hole 6014 and enters the rectangular groove 6012, so that one end of the fastening bolt 606 cooperates with the positioning groove on the locking block 605 to lock the locking block 605. When the bottom of the vehicle is scraped or hit, the impact force generated by the impact will cause the battery pack 7 to vibrate. The battery pack 7 is effectively fixed by the four locking blocks 605, so that the battery pack 7 can remain stable when vibration occurs.
