Description

Technical Field

[0001] This utility model relates to the field of automotive battery technology, and in particular to a safety protection component for automotive battery brackets. Background Technology

[0002] A car battery mount is a component used to secure a car battery, preventing it from moving or vibrating during vehicle operation. It is crucial for protecting the battery from physical damage and ensuring the stable operation of the electrical system. Battery mounts are typically made of metal (such as steel or aluminum) or high-strength plastic and are designed to be securely installed in specific locations within the vehicle.

[0003] The related technology, with publication number CN220042079U, discloses a new energy vehicle battery bracket tray with an anti-collision structure. The tray includes a car battery tray with brackets installed on both outer walls. Its structure is reasonable. This invention incorporates an anti-collision bar and anti-collision components. The anti-collision bar, along with a damper and spring A, is fixedly installed on one side of the brackets on the car battery tray. The anti-collision components are installed at the center between the anti-collision bar and the brackets. Utilizing the elastic buffering effect of the anti-collision components, the anti-collision components can cushion the anti-collision bar. Simultaneously, the damper and spring A effectively increase the buffering effect of the anti-collision bar. By taking anti-collision measures on the brackets of the car battery tray, the impact on the battery of the new energy vehicle can be effectively prevented, thus improving the protection and safety of the new energy vehicle battery bracket tray.

[0004] While existing automotive battery mount trays offer some impact protection, their design suffers from a significant problem: poor adaptability to battery outer diameters, making it difficult to adjust the clamping force according to different battery sizes. This results in insufficient support during use, especially during battery installation and removal. The lack of adequate clamping force can lead to battery instability or even damage. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes a safety protection component for automotive battery brackets. The elastic support can automatically adjust the relative distance between the support base frame and the upper pressure frame according to the outer diameter of the battery pack, ensuring the stable placement of the battery pack under different sizes. At the same time, the first and second fasteners, based on the elastic support, can automatically limit the four sides of the battery pack, further enhancing the stability and reliability of the support.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a car battery bracket safety protection component, including a supporting base frame, an upper pressure frame disposed relative to the supporting base frame, elastic support members disposed at the four peripheral corners between the supporting base frame and the upper pressure frame, a first fastener disposed between the supporting base frame and the upper pressure frame, and a second fastener disposed in a mirror image of the first fastener.

[0007] By adopting the above technical solution, and through the coordinated work of the supporting base frame, upper pressure frame, elastic support, first fastener, and second fastener, a function of automatically adapting to the size of the battery pack and providing stable support is achieved. Specifically, the elastic support can automatically adjust the relative distance between the supporting base frame and the upper pressure frame according to the outer diameter of the battery pack, ensuring the stable placement of the battery pack under different sizes; at the same time, based on the elastic support, the first and second fasteners can automatically limit the movement of the battery pack around its perimeter, further enhancing the stability and reliability of the support.

[0008] As a preferred embodiment, the elastic support includes a support slide cylinder fixedly disposed at the four corners of the support base frame, a support slide rod fixedly disposed at the four corners of the lower end face of the upper pressure frame, and a support spring disposed on the outer periphery of the support slide rod. The support slide cylinder and the support slide rod are slidably connected to each other, and the support slide cylinder is provided with a sliding hole adapted to the support slide rod.

[0009] By adopting the above technical solution, it is easier for the support slide rod to slide around the sliding hole.

[0010] As a preferred embodiment, one end of the support spring is fixedly connected to the end of the support slide cylinder that is away from the support base frame, and the other end of the support spring is fixedly connected to the end of the support slide cylinder that is away from the support slide rod cylinder.

[0011] By adopting the above technical solution, the elastic support component achieves clamping and fixing of the upper and lower end faces of the battery pack through the cooperation of the support slide cylinder and the support slide rod, as well as the connection of the support spring.

[0012] As a preferred embodiment, the first fastener and the second fastener are respectively provided in the inner cavity of the support base frame, in the inner cavity of the upper pressure frame, in the first pressure rod, in the second pressure rod, in the first connecting rod for connecting one end of the first pressure rod and the second pressure rod, and in the second connecting rod for connecting the other end of the first pressure rod and the second pressure rod, wherein the first pressure rod and the second pressure rod are respectively configured as "U" shape.

[0013] By adopting the above technical solution, this design facilitates the connection of the two ends of the first pressure rod and the second pressure rod to the first connecting rod and the second connecting rod, respectively.

[0014] As a preferred embodiment, the first pressure rod and the second pressure rod are respectively configured as telescopic rods, and the first pressure rod and the second pressure rod are respectively engaged with and slidably connected to the supporting bottom frame and the upper pressure frame.

[0015] By adopting the above technical solution, a structure with an adjustable inner diameter is formed by setting a first pressure rod in the inner cavity of the supporting bottom frame and a second pressure rod in the inner cavity of the upper pressure frame, and connecting the two ends of the two pressure rods by a first connecting rod and a second connecting rod. Since both the first and second pressure rods are telescopic rods, and they are respectively engaged and slidably connected to the supporting bottom frame and the upper pressure frame, the distance between the first and second pressure rods can be easily adjusted during extension and retraction, thereby changing the inner diameter of the battery pack being held.

[0016] As a preferred embodiment, the two ends of the first connecting rod and the second connecting rod are respectively provided with a fixing pin and a fixing nut for fixing the fixing pin at the connection points with the first pressure rod and the second pressure rod. The fixing pin is fixedly connected to the first pressure rod and the second pressure rod respectively, and the fixing pin is rotatably connected to the first connecting rod and the second connecting rod respectively.

[0017] By adopting the above technical solution, fixing pins and fixing nuts are respectively set at the connection points of the first connecting rod and the second connecting rod with the first pressure rod and the second pressure rod, so that the fixing pins are fixedly connected to the first pressure rod and the second pressure rod, and are rotatably connected to the first connecting rod and the second connecting rod. This makes it easy to adjust the vertical height of the first pressure rod and the second pressure rod by fixing pins, thereby adapting to battery packs with different outer diameters and ensuring safe and stable compression of the battery pack.

[0018] As a preferred embodiment, the fixing pin passes through the first pressure rod and the second pressure rod and is connected to the fixing nut, and a buffer pad is provided on the outer periphery of the fixing nut.

[0019] By adopting the above technical solution, a fixing pin passes sequentially through the first and second pressure rods and is then connected to a fixing nut, thereby achieving a fixed connection between the two pressure rods. The buffer pad on the outer periphery of the fixing nut effectively prevents damage to the battery pack when the fixing nut comes into direct contact with it.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0032] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the car battery bracket safety protection assembly includes a supporting base frame 11, an upper pressure frame 12 disposed relative to the supporting base frame 11, and elastic support members 3 respectively disposed at the four corners between the supporting base frame 11 and the upper pressure frame 12. The elastic support members 3 include support slide cylinders 31 respectively fixedly disposed at the four corners of the supporting base frame 11, support slide rods 32 respectively fixedly disposed at the four corners of the lower end face of the upper pressure frame 12, and support springs 321 disposed on the outer periphery of the support slide rods 32. The support slide cylinders 31 and the support slide rods 32 slide relative to each other. The support slide cylinder 31 is connected to the support slide rod 32, and a sliding hole adapted to the support slide rod 32 is provided on the support slide cylinder 31, so that the support slide rod 32 can slide around the sliding hole as the center. One end of the support spring 321 is fixedly connected to the end of the support slide cylinder that is away from the support base frame 11, and the other end of the support spring 321 is fixedly connected to the end of the support slide cylinder that is away from the support slide rod 32. The elastic support member 3 achieves clamping and fixing of the upper and lower end faces of the battery pack through the cooperation of the support slide cylinder 31 and the support slide rod 32, and the connection of the support spring 321. Its specific working principle is as follows: the support slide cylinder 31 is fixedly set at the four perimeter corners of the support base frame 11, and the support slide rod 32 is fixedly set at the lower end face of the four perimeter corners of the upper pressure frame 12. One end of the support spring 321 is fixedly connected to the end of the support slide cylinder that is away from the support base frame 11, and the other end is fixedly connected to the end of the support slide cylinder that is away from the support slide rod 32, so that the length of the support spring 321 can be adjusted as the support slide rod 32 slides in the support slide cylinder 31. When it is necessary to clamp and fix the battery pack, pressure is applied to the support slide rod 32 by the upper pressure frame 12. The support slide rod 32 slides in the sliding hole in the support slide cylinder 31, and the support spring 321 extends and retracts accordingly, automatically adjusting the distance between the support slide rod 32 and the support slide cylinder 31. This achieves precise adjustment of the distance between the support bottom frame 11 and the upper pressure frame 12, and finally effectively clamps and fixes the upper and lower end faces of the battery pack.

[0036] Please refer to details. Figure 1 , Figure 2 and Figure 4The system includes a first fastener 21 disposed between the support base frame 11 and the upper pressure frame 12, and a second fastener 22 disposed mirror-image of the first fastener 21. The first fastener 21 and the second fastener 22 are respectively disposed within the inner cavity of the support base frame 11 (first pressure rod 41), the inner cavity of the upper pressure frame 12 (second pressure rod 42), a first connecting rod 431 for connecting one end of the first pressure rod 41 and the second pressure rod 42, and a second connecting rod 432 for connecting the other end of the first pressure rod 41 and the second pressure rod 42. The first pressure rod 41 and the second pressure rod 42 are respectively configured as "U" shapes. This design facilitates the connection of the two ends of the first pressure rod 41 and the second pressure rod 42 to the first connecting rod 431 and the second connecting rod 432, respectively. The first pressure rod 41 and the second pressure rod 42 are respectively configured as telescopic rods, and are respectively engaged and slidably connected to the supporting base frame 11 and the upper pressure frame 12. By setting the first pressure rod 41 in the inner cavity of the supporting base frame 11 and the second pressure rod 42 in the inner cavity of the upper pressure frame 12, and connecting the two ends of these two pressure rods through the first connecting rod 431 and the second connecting rod 432, an adjustable inner diameter structure is formed. Since both the first pressure rod 41 and the second pressure rod 42 are telescopic rods, and they are engaged and slidably connected to the supporting base frame 11 and the upper pressure frame 12, the distance between the first pressure rod 41 and the second pressure rod 42 can be easily adjusted during telescopic movement, thereby changing the inner diameter of the clamped battery pack. In actual operation, the lengths of the first pressure rod 41 and the second pressure rod 42 are first adjusted according to the size of the battery pack to be clamped. Through the telescopic extension of the telescopic rod and its sliding connection with the support base frame 11 and the upper pressure frame 12, the first pressure rod 41 and the second pressure rod 42 can fit tightly against the inner wall of the battery pack, thereby achieving precise clamping and fixing of the battery pack. The whole process is flexible and efficient, meeting the clamping requirements of different battery pack sizes.

[0037] Please refer to details. Figure 1 , Figure 2 and Figure 3At the two ends of the first connecting rod 431 and the second connecting rod 432, where they connect to the first pressure rod 41 and the second pressure rod 42, a fixing pin 441 and a fixing nut 442 for fixing the fixing pin 441 are respectively provided. The fixing pin 441 is fixedly connected to the first pressure rod 41 and the second pressure rod 42, and the fixing pin 441 is rotatably connected to the first connecting rod 431 and the second connecting rod 432. By setting the fixing pin 441 and the fixing nut 442 at the two ends of the first connecting rod 431 and the second connecting rod 432, the fixing pin 441 is fixedly connected to the first pressure rod 41 and the second pressure rod 42, and is rotatably connected to the first connecting rod 431 and the second connecting rod 432. This allows for adjustment of the vertical height of the first pressure rod 41 and the second pressure rod 42 through the fixing pin 441, thereby adapting to battery packs of different outer diameters and ensuring safe and stable compression of the battery pack.

[0038] Please refer to details. Figure 2 , Figure 3 and Figure 4 A fixing pin 441 passes through the first pressure rod 41 and the second pressure rod 42 and connects to the fixing nut 442. A buffer pad is provided on the outer periphery of the fixing nut 442. The fixing pin 441 passes sequentially through the first pressure rod 41 and the second pressure rod 42 before connecting to the fixing nut 442, thus achieving a fixed connection between the two pressure rods. The buffer pad on the outer periphery of the fixing nut 442 effectively prevents damage to the battery pack when the fixing nut 442 directly contacts the battery pack.

[0039] In this embodiment, during use, the battery pack is placed between the first pressure rod 41 and the second pressure rod 42. The first pressure rod 41 and the second pressure rod 42 are subjected to the force of the outer diameter of the battery pack. Utilizing their own telescopic characteristics, they adapt to the outer diameter of the battery pack and fit against it. During this process, the first connecting rod 431 and the second connecting rod 432 rotate around the fixed pin 441 due to the supporting force of the battery pack, adaptively adjusting the vertical height of the first pressure rod 41 and the second pressure rod 42. During the clamping and fixing of the battery pack, the upper pressure frame 12 applies pressure to the support slide rod 32. The support slide rod 32 slides in the sliding hole in the support slide cylinder 31, and the support spring 321 extends and retracts accordingly, automatically adjusting the distance between the support slide rod 32 and the support slide cylinder 31. This achieves precise adjustment of the distance between the support bottom frame 11 and the upper pressure frame 12, and finally effectively clamps and fixes the upper and lower end faces of the battery pack, thereby effectively ensuring the stability of clamping and fixing the battery pack.

[0040] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
