Description

Technical Field

[0001] This utility model relates to the field of electric vehicle battery technology, specifically to an electric vehicle battery collision avoidance device. Background Technology

[0002] With the global energy crisis and increasing awareness of environmental protection, electric vehicles, as an important carrier of green travel, are experiencing a rapid and continuous increase in market share. However, amidst the wave of electric vehicle adoption, battery safety remains a core concern for consumers. As the power source of vehicles, electric vehicle batteries have a complex structure and store a large amount of energy. When subjected to external impacts such as collisions, they are highly susceptible to shell rupture, cell short circuits, and electrolyte leakage, which can lead to serious safety accidents such as fires and explosions. This not only causes huge property losses but also poses a fatal threat to the lives of passengers and those around them.

[0003] Currently, most of the existing protection methods for electric vehicle batteries are limited to passive protection. On the one hand, they rely on the material strength of the battery casing itself, such as using high-strength alloys or composite materials to construct the casing, hoping to resist external collisions through the impact resistance of the casing. On the other hand, they rely on the protective structure of the vehicle chassis, such as setting a metal guard plate under the battery, to reduce damage caused by bottom impacts.

[0004] However, the above-mentioned protective measures have obvious limitations. When a vehicle encounters a severe frontal, side or bottom collision, especially a collision at high speed, the external impact force often far exceeds the withstand limit of the passive protection structure, which can easily cause battery damage, fire and other situations, resulting in a safety accident.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric vehicle battery collision avoidance device, comprising a collision avoidance frame, a battery pack, and a heat dissipation plate, wherein the battery pack is installed inside the collision avoidance frame, and the heat dissipation plate is installed on the outside of the collision avoidance frame.

[0007] The collision avoidance frame includes a frontal collision frame, a frontal reinforcement beam, a connecting block, a side collision frame, a side reinforcement beam, and a limiting slide rail. The frontal reinforcement beam is fixedly connected to the inner side of the frontal collision frame, the connecting block is fixedly connected to one end of each side of the frontal collision frame, the side collision frame is fixedly connected to one end of the connecting block, the side reinforcement beam is fixedly connected to the inner side of the side collision frame, and the limiting slide rail is fixedly connected to the top and bottom of the frontal collision frame.

The connecting plate is fixedly connected to the connecting block, and the break groove is formed at the connection between the fixing block and the connecting plate. By setting a break groove between the fixing block and the connecting plate, the connecting block can be broken by the connecting plate when subjected to severe impact, reducing the impact force on the battery pack and allowing the battery to detach from the vehicle body, thus preventing fire and serious accidents to the vehicle body.

[0009] Preferably, the battery pack includes a battery body, an upper slide bar, and a side slide bar. The upper slide bar is fixedly connected to the top and bottom of the battery body, and the side slide bar is fixedly connected to both sides of the battery body.

Through the directional sliding groove, the battery pack can slide to get rid of the collision avoidance frame when it is hit, so as to provide safety protection.

[0011] Preferably, the number of limiting slide rails is four, which are evenly distributed at the upper and lower ends of the collision avoidance frame, which can effectively protect the battery pack and, together with the heat dissipation plate, support the battery pack.

[0012] Preferably, the heat dissipation plate is provided with heat dissipation holes to ensure that the battery pack maintains heat dissipation during operation.

[0013] Preferably, the front reinforcing beam and the side reinforcing beam are made of alloy reinforced steel, which can withstand large impacts and remain undeformed, thereby causing the entire battery pack to shift.

[0014] Preferably, the structure of the upper and lower slide bars is consistent with the structure of the connecting block, which facilitates the sideways release of the battery pack.

[0015] Preferably, a buffer pad is provided on the outside of the battery pack to increase the protection of the battery pack.

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.

[0026] Please see Figure 1-5The present invention provides the following technical solution: an electric vehicle battery collision avoidance device, including a collision avoidance frame 1, a battery pack 2 and a heat dissipation plate 3. The battery pack 2 is installed inside the collision avoidance frame 1, and the heat dissipation plate 3 is installed on the outside of the collision avoidance frame 1. The heat dissipation plate 3 is provided with heat dissipation holes and grooves to ensure that the battery pack 2 maintains heat dissipation during operation. A buffer pad is provided on the outside of the battery pack 2 to increase the protection of the battery pack 2.

[0027] The collision avoidance frame 1 includes a frontal collision frame 101, a frontal reinforcing beam 102, a connecting block 103, a side collision frame 104, a side reinforcing beam 105, and a limiting slide rail 106. The frontal reinforcing beam 102 is fixedly connected to the inner side of the frontal collision frame 101. The connecting block 103 is fixedly connected to one end of each side of the frontal collision frame 101. The side collision frame 104 is fixedly connected to one end of the connecting block 103. The side reinforcing beam 105 is fixedly connected to the inner side of the side collision frame 104. The limiting slide rail 106 is fixedly connected to the top and bottom of the frontal collision frame 101. The frontal collision frame 101, the frontal reinforcing beam 102, the connecting block 103, and the side collision frame 104 together provide protection for the battery pack 2, ensuring the safety of the battery pack. For the safety of battery pack 2, a groove is provided on the inner side of the front reinforcing beam 102 and a groove is provided at the bottom of the limiting slide rail 106. The front reinforcing beam 102 is slidably connected to the side slide bar 203, and the limiting slide rail 106 is slidably connected to the upper and lower slide bars 202. Through the directionally set groove, the battery pack 2 can slide and get away from the collision avoidance frame 1 when it is hit, so as to provide safety protection. There are four limiting slide rails 106, which are evenly distributed at the upper and lower ends of the collision avoidance frame 1, which can effectively protect the battery pack 2. Together with the heat dissipation plate 3, they play a supporting role for the battery pack 2. The front reinforcing beam 102 and the side reinforcing beam 105 are made of alloy reinforced steel, which can withstand a large impact and remain undeformed, thereby driving the overall displacement of the battery pack 2.

[0028] The connecting block 103 includes a fixing block 110, a connecting plate 111, and a break groove 112. The fixing block 110 is fixedly connected to one end of the frontal collision frame 101, and the connecting plate 111 is fixedly connected to the other end of the fixing block 110. The connecting plate 111 is fixedly connected to the connecting block 103. The break groove 112 is opened at the connection between the fixing block 110 and the connecting plate 111. By setting the break groove 112 between the fixing block 110 and the connecting plate 111, the connecting block 103 can be broken by the connecting plate 111 when subjected to a severe impact, reducing the impact force on the battery pack 2 and allowing the battery to detach from the vehicle body, avoiding fire and serious accidents to the vehicle body. The structure of the upper and lower sliding rods 202 is the same as the structure of the connecting block 103, which facilitates the side escape of the battery pack 2.

[0029] The battery pack 2 includes a battery body 201, an upper and lower sliding rod 202, and a side sliding rod 203. The upper and lower sliding rod 202 is fixedly connected to the top and bottom of the battery body 201, and the side sliding rod 203 is fixedly connected to both sides of the battery body 201.

[0030] In use, the battery pack 2 is installed inside the collision avoidance frame 1. The upper and lower sliding rods 202 are connected to the limiting slide rails 106, and the side sliding rods 203 are connected to the inner side of the front reinforcing beam 102. When a collision occurs, the front collision frame 101 is impacted, and the front reinforcing beam 102 will move backward, breaking the connecting block 103 from the front, providing displacement space for the battery pack 2, thereby reducing the impact on the battery pack 2. The same applies when the side is impacted; the connecting block 103 breaks, and the battery pack 2 moves laterally along the side sliding rods 203.

[0031] 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 the 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.
