Description

Technical Field

[0001] The utility model relates to the technical field of power batteries, and more specifically, to a power battery protection plate. Background Art

[0002] A power battery is a power source that provides power for tools, mostly referring to batteries that power electric vehicles, electric trains, electric bicycles, and golf carts.

[0003] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles and other new energy vehicles. Among them, a pure electric vehicle is a vehicle that uses a single battery as a storage power source. It uses a battery as a storage power source, provides electricity to the electric motor through the battery, drives the electric motor to operate, and thus drives the vehicle. The battery inside a pure electric new energy vehicle needs to be firmly fixed on the chassis of the vehicle.

[0004] At present, when fixing the battery to the chassis of a new energy vehicle, the battery and the chassis are fixed by screws, which results in low protection performance of the bottom of the battery. With the popularization of new energy vehicles, there have been cases where the bottom of the vehicle was hit and the power battery was hit, resulting in explosion. It can be seen that the protection performance of the bottom of the existing power battery is low. Therefore, a power battery protection plate is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a power battery protection board to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a power battery protection plate, comprising a battery box, a battery body installed in the battery box, a plurality of top support assemblies installed at the bottom of the battery box, dampers installed in the middle of the four sides of the bottom of the battery box, the top support assemblies are slidably connected to a protective assembly, the protective assembly is connected to each damper, a rubber pad is installed at the bottom of the protective assembly, and the protective assembly is sleeved on the bottom of the battery box.

[0007] Preferably, the supporting assembly includes a bolt rod and a spring, the bolt rod is installed at the bottom of the battery box, and a limiting nut is installed at the end of the bolt rod, the bolt rod is slidably connected to the protective assembly, and the spring is sleeved on the bolt rod.

[0008] Preferably, the protection component includes a base plate, a connecting frame and a connecting plate. The connecting frame is provided on the top of the base plate, and the connecting plate is provided on the top of the connecting frame. The base plate, the connecting frame and the connecting plate are integrally formed.

[0009] Preferably, the outside of the bottom end of the battery box is a step structure, while the inside of the battery box is a square structure. The side of the connection between the bottom plate and the connecting frame is inclined, and the inclined side is parallel to the inclined surface of the step connected to the battery box, and the protective component is sleeved on the bottom of the battery box.

[0010] The technical effects and advantages of this utility model are:

[0011] 1. The rubber pad is used to properly cushion the impact force and reduce the collision noise. When the bottom is hit hard during driving, the impact force impacts the bottom plate of the bottom of the protective component, causing the bottom plate to move upward, so that the connecting plate squeezes the various springs, and the various bolt rods cooperate to guide, so that the battery box supports the inner wall where the connecting frame and the connecting plate are connected, so that the bottom plate is subjected to tearing force. The bottom plate is a flat structure, so it can withstand greater impact intensity when it is torn horizontally. In the case of the toughness of the protective component itself, the deformation buffer cavity provides a certain amount of activity space, thereby avoiding the bottom plate from directly colliding with the bottom of the battery box after being impacted. After the impact force disappears, the toughness of the protective component itself cooperates with the damper to reset, thereby increasing the impact resistance and improving the protection of the battery, thereby improving the safety of the installation and use of power batteries in new energy vehicles. At the same time, it avoids repeated vibrations caused by collisions, thereby reducing the generation of noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 making creative efforts are within the scope of protection of the present invention.

[0018] As attached Figure 1-4 A power battery protection plate shown in the figure includes a battery box 1, a battery body 2 is installed in the battery box 1, a plurality of top support components 3 are installed at the bottom of the battery box 1, and dampers 4 are installed in the middle of the four sides of the bottom of the battery box 1. The top support components 3 are slidably connected to the protective components 5, and the protective components 5 are connected to each damper 4. A rubber pad 6 is installed at the bottom of the protective component 5, and the protective component 5 is sleeved on the bottom of the battery box 1.

[0019] In a specific implementation, the battery box 1 is installed at the bottom of the car. When the bottom of the car is slightly hit during driving, the rubber pad 6 appropriately cushions the impact force and reduces the collision noise. When the bottom of the car is hit hard during driving, the impact force impacts the bottom plate 501 at the bottom of the protective component 5, causing the bottom plate 501 to move upward, thereby causing the connecting plate 503 to squeeze each spring 302, and each bolt rod 301 cooperates with the guide, so that the battery box 1 supports the inner wall where the connecting frame 502 and the connecting plate 503 are connected, so that the bottom plate 501 is subjected to the tearing force, and the bottom plate 501 is subjected to the tearing force. The plate 501 is a flat structure, so it can withstand greater impact intensity when it is torn horizontally. In the case of the toughness of the protective component 5 itself, the deformation buffer cavity 7 provides a certain amount of activity space, thereby preventing the bottom plate 501 from directly colliding with the bottom of the battery box 1 after being impacted. After the impact force disappears, the toughness of the protective component 5 itself cooperates with the damper 4 to reset, thereby increasing the impact resistance and improving the protection of the battery, thereby improving the safety of the installation and use of power batteries in new energy vehicles. At the same time, it avoids repeated vibrations caused by collisions, thereby reducing the generation of noise.

[0020] The supporting assembly 3 includes a bolt rod 301 and a spring 302. The bolt rod 301 is installed at the bottom of the battery box 1, and a limiting nut is installed at the end of the bolt rod 301. The bolt rod 301 is slidably connected to the protective assembly 5, and the spring 302 is sleeved on the bolt rod 301.

[0021] In specific implementation, the connection between the protective component 5 and the bolt rod 301 can be limited by the setting of the limit nut, and the spring 302 cooperates with the setting of the limit nut to adjust the depth of the deformation buffer cavity 7 of the protective component 5.

[0022] The protection component 5 includes a base plate 501, a connecting frame 502 and a connecting plate 503. The connecting frame 502 is provided on the top of the base plate 501, and the connecting plate 503 is provided on the top of the connecting frame 502. The base plate 501, the connecting frame 502 and the connecting plate 503 are integrally formed.

[0023] The outside of the bottom end of the battery box 1 is a step structure, while the inside of the battery box 1 is a square structure. The side surface at the connection between the bottom plate 501 and the connecting frame 502 is inclined, and the inclined side surface is parallel to the step slope connected to the battery box 1, and the protective component 5 is sleeved on the bottom of the battery box 1.

[0024] In specific implementation, when the protective component 5 is impacted, the area of ​​the contact surface between the battery box 1 and the protective component 5 can be increased, so that the impact force can be dispersed to a greater extent, thereby further improving the tear resistance of the bottom plate 501, thereby improving the impact resistance. The protective component 5 is sleeved on the battery box 1, which can make the overall structure more compact and reduce the space occupied.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
