Description

Technical Field

[0001] This utility model relates to the field of power battery storage technology, and in particular to a battery box with anti-collision beam. Background Technology

[0002] A battery box is a housing structure used to house and protect power battery packs. It is widely used in electric vehicles, electric forklifts, energy storage equipment and other fields. Its main function is to provide physical protection, dust and water resistance and structural support for the battery pack, ensuring that the battery pack can work in a stable environment.

[0003] In actual use, battery boxes may face external impacts such as collisions and compression, such as scrapes during electric vehicle operation or collisions during electric forklift operation. If these impacts are directly applied to the battery pack, they may cause battery deformation, leakage, or even safety accidents. Battery boxes with anti-collision beams are protective devices that add anti-collision beam structures to the traditional battery box. The anti-collision beams can absorb and disperse impact forces through their own deformation, reducing the impact force transmitted to the battery pack, thereby improving the battery box's anti-collision capability.

[0004] The existing battery box with anti-collision beam has the following shortcomings:

[0005] Because there is no dedicated buffer and anti-collision structure at the bottom, when the bottom is impacted, the impact force cannot be effectively dispersed and buffered, and it directly acts on the battery pack inside the battery box, which can easily lead to damage to the battery pack. At the same time, the existing device has a complicated connection method between the anti-collision component and the battery box, which requires multiple steps and professional tools for installation. This not only results in low installation efficiency, but also makes it inconvenient to disassemble and maintain the anti-collision component later. Utility Model Content

[0006] This utility model proposes a battery box with anti-collision beam, which has the beneficial effects of effectively buffering the bottom impact, protecting the battery box safety, and the anti-collision components are easy to install and maintain, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a battery box with anti-collision beam, including a power battery box, an anti-collision component is fixedly installed at the bottom of the power battery box, the anti-collision component includes an anti-collision base plate, three buffer brackets are fixedly connected to the top of the anti-collision base plate, and connecting brackets are rotatably hinged to the left and right sides of the top of the buffer brackets.

[0008] The buffer bracket includes a portal-shaped support plate, which is disposed on the lower surface of the power battery box. Guide slide rods are fixedly connected to the front and rear sides of the bottom of the portal-shaped support plate. A trapezoidal slider is slidably connected to the left and right sides of the outer surfaces of the two guide slide rods. Two buffer springs are fixedly connected to the opposite sides of the two trapezoidal sliders. An inclined groove is opened on the opposite surface of the two trapezoidal sliders. A trapezoidal top plate is slidably connected to the inner surface of the two inclined grooves. The trapezoidal top plate is fixedly connected to the upper surface of the anti-collision base plate.

[0009] Preferably, the buffer spring is disposed on the outer surface of the guide slide rod, and the side of the buffer spring away from the trapezoidal slider is fixedly connected to the inner surface of the anti-collision base plate.

[0010] Preferably, the inner surface of the inclined slide groove has limit slide grooves on both the front and rear sides, and the trapezoidal top plate has two limit sliders fixedly connected to both the front and rear sides, and the limit sliders are slidably connected inside the limit slide grooves.

[0011] Preferably, two connecting blocks are fixedly connected to both the left and right sides of the power battery box, and the connecting frame is rotatably engaged with the outer surface of the connecting blocks.

[0012] Preferably, the top front and rear sides of the connecting frame are rotatably connected to knobs, and the bottom of the knobs is fixedly connected to threaded posts.

[0013] Preferably, threaded holes are provided on both the front and rear sides of the top of the connecting block, and the bottom end of the threaded column extends through to the inner side of the connecting frame and its outer surface is threadedly connected to the inner surface of the threaded hole.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. In this utility model, the effective buffering of bottom impact is achieved through the cooperation of the buffer bracket, trapezoidal slider, buffer spring, trapezoidal top plate, etc. The principle is that when the anti-collision bottom plate is squeezed, it will push the trapezoidal top plate to slide upward. The sliding of the limiting slider in the limiting groove limits the sliding range of the trapezoidal top plate. The trapezoidal top plate, through the sliding cooperation with the inclined groove, pushes the two trapezoidal sliders to slide to the left and right along the guide slide rod and squeezes the buffer spring, thereby dispersing the upward impact force to both sides, avoiding the impact force from acting directly on the power battery box, and effectively protecting the safety of the power battery box and the internal battery pack.

[0016] 2. In this utility model, the installation of the anti-collision component is made more convenient through the cooperation between the connecting frame, connecting block, knob, threaded post, and threaded hole. The principle is that when connecting, the upper surface of the buffer bracket is attached to the power battery box, the connecting frame is rotated to make it lock onto the outside of the connecting block, and then the knob is rotated to screw the threaded post into the threaded hole, thus completing the connection and fixation between the anti-collision component and the power battery box. This connection method is simple and does not require professional tools, which not only improves the installation efficiency, but also facilitates the disassembly and maintenance of the anti-collision component in the later stage.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a technical solution: including a power battery box 1, with an anti-collision component 2 fixedly installed at the bottom of the power battery box 1, the anti-collision component 2 including an anti-collision base plate 21, three buffer brackets 22 fixedly connected to the top of the anti-collision base plate 21, connecting brackets 23 rotatably hinged to the left and right sides of the top of the buffer brackets 22, two connecting blocks 11 fixedly connected to the left and right sides of the power battery box 1, the connecting brackets 23 rotatably snapped onto the outer surface of the connecting blocks 11, knobs 231 rotatably connected to the front and rear sides of the top of the connecting brackets 23, threaded posts 232 fixedly connected to the bottom of the knobs 231, threaded holes 12 opened on the front and rear sides of the top of the connecting blocks 11, the bottom end of the threaded post 232 penetrates to the inner side of the connecting bracket 23 and the outer surface is threadedly connected to the inner surface of the threaded hole 12;

[0025] The overall effect of embodiment 1 is as follows: it realizes a quick and stable connection between the anti-collision component 2 and the power battery box 1. Through the snap-fit ​​cooperation between the connecting bracket 23 and the connecting block 11, and the locking method of the knob 231 driving the threaded post 232 into the threaded hole 12, the installation can be completed without complicated tools. This not only improves the assembly efficiency, but also makes it easy to disassemble when the anti-collision component 2 needs to be replaced or maintained. Simply turn the knob 231 in the opposite direction to make the threaded post 232 disengage from the threaded hole 12, which greatly improves the convenience of operation.

[0026] Example 2: As Figure 3 - Figure 4 As shown, this utility model provides a technical solution: the buffer bracket 22 includes a portal-shaped support plate 221, which is disposed on the lower surface of the power battery box 1. Guide slide rods 222 are fixedly connected to the front and rear sides of the bottom of the portal-shaped support plate 221. A trapezoidal slider 223 is slidably connected to the left and right sides of the outer surface of each guide slide rod 222. Two buffer springs 224 are fixedly connected to the opposite sides of each trapezoidal slider 223. Inclined grooves 225 are provided on the opposite sides of each trapezoidal slider 223. A trapezoidal top plate 227 is slidably connected to the inner surface of the 25. The trapezoidal top plate 227 is fixedly connected to the upper surface of the anti-collision base plate 21. A buffer spring 224 is set on the outer surface of the guide slide rod 222. The side of the buffer spring 224 away from the trapezoidal slider 223 is fixedly connected to the inner surface of the anti-collision base plate 21. Limiting slide grooves 226 are opened on both the front and rear sides of the inner surface of the inclined slide groove 225. Two limiting sliders 228 are fixedly connected to both the front and rear sides of the trapezoidal top plate 227. The limiting sliders 228 are slidably connected inside the limiting slide grooves 226.

[0027] The overall effect of Embodiment 2 is as follows: an efficient bottom impact buffer mechanism is constructed. When the anti-collision bottom plate 21 is impacted by an external force, the trapezoidal top plate 227 moves upward and pushes the trapezoidal slider 223 to slide along the guide rod 222 to both sides through the inclined slide groove 225. The buffer spring 224 is compressed and absorbs the impact energy. At the same time, the limiting slider 228 slides in the limiting slide groove 226, ensuring that the movement of the trapezoidal top plate 227 and the trapezoidal slider 223 is stable and orderly. The vertical impact force is effectively converted into the horizontal spring force, which greatly reduces the impact force transmitted to the power battery box 1 and provides reliable protection for the battery pack.

[0028] The working principle of the entire device is as follows: When installing the anti-collision component 2, first, attach the portal-shaped support plate 221 of the buffer bracket 22 to the lower surface of the power battery box 1, rotate the connecting bracket 23 to make it snap into the outside of the connecting block 11, then rotate the knob 231 to drive the threaded post 232 into the threaded hole 12 on the connecting block 11 until the connecting bracket 23 and the connecting block 11 are tightly fitted, completing the fixed installation of the anti-collision component 2 and the power battery box 1. When the bottom of the power battery box 1 is hit by an external impact, the impact force is first... The impact force is first applied to the anti-collision base plate 21, which then transmits the impact force to the trapezoidal top plate 227, causing it to move upwards. During this movement, the trapezoidal top plate 227 slides relative to the inclined grooves 225 of the trapezoidal slider 223 on both sides. Due to the inclined angle design of the inclined grooves 225, a pushing force is generated on the trapezoidal slider 223 to the left and right, causing the two trapezoidal sliders 223 to slide in opposite directions along the guide rod 222. At this time, the trapezoidal sliders 223 will compress the buffer on their opposite sides. The impact spring 224 absorbs a large amount of impact energy due to deformation, converting the originally concentrated impact force into the elastic potential energy of the spring, thus dispersing and buffering the impact force. At the same time, when the trapezoidal top plate 227 and the trapezoidal slider 223 slide relative to each other, the limiting slider 228 on the trapezoidal top plate 227 slides synchronously within the limiting groove 226 of the trapezoidal slider 223, preventing the trapezoidal top plate 227 from separating or shifting from the trapezoidal slider 223, ensuring the stable operation of the buffer structure. When the external impact force disappears, the buffer spring 224 releases its elastic potential energy, pushing the trapezoidal slider 223 to reset along the guide rod 222. The trapezoidal slider 223 drives the trapezoidal top plate 227 downward through the inclined groove 225, causing the anti-collision bottom plate 21 to return to its initial position. The entire buffer structure completes its reset and awaits the buffering work of the next impact. Through this series of structural coordination, effective buffering of the impact on the bottom of the power battery box 1 is achieved, while ensuring the convenience of installation and maintenance of the anti-collision component 2.
