Abstract

This invention belongs to the field of battery pack vibration damping technology, and specifically relates to an adjustable nonlinear damping energy storage battery, comprising a battery pack, a battery frame, and a battery housing, wherein the battery housing is fitted and fixed to the outside of the battery frame. This invention, by incorporating linear and nonlinear damping components, provides better protection for the battery pack. Furthermore, the two nonlinear damping frames within the nonlinear damping component, in conjunction with a coil spring, an offset turntable, and a crank, constitute a dual-end damping system for the battery pack, further enhancing the overall damping effect and structural stability.

Moreover, the U-shaped block and adjusting screw allow for adjustment of the coil spring's coiling degree, thereby adjusting the preload of the coil spring to accommodate battery packs of different weights.

Description

Technical Field

[0001] This invention relates to the field of battery pack vibration resistance technology, specifically to an adjustable nonlinear vibration-damping energy storage battery. Background Technology

[0002] Currently, energy storage batteries are increasingly used in transportation, industrial equipment and other fields, and these application scenarios are often accompanied by relatively complex vibration environments.

[0003] Traditional energy storage battery vibration damping structures mostly adopt linear vibration damping methods, and their vibration damping characteristic curves are linear, making it difficult to adapt to vibration inputs of different frequencies and amplitudes.

[0004] In actual working conditions, when the vibration intensity is low, the linear damping structure may not be able to provide sufficient buffering; while when the vibration intensity is high, the battery may be subjected to a large impact due to insufficient damping stroke, thereby affecting the battery's service life and safety.

[0005] In addition, most existing nonlinear damping structures are designed with fixed parameters, which cannot be flexibly adjusted according to changes in the weight of the battery pack or specific vibration environment requirements, resulting in poor versatility and adaptability. Therefore, we propose an adjustable nonlinear damping energy storage battery to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an adjustable nonlinear damping energy storage battery, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention specifically adopts the following technical solution: An adjustable nonlinear damping energy storage battery includes a battery pack, a battery frame, and a battery housing. The battery housing is sleeved and fixed on the outside of the battery frame. A linear damping component is provided inside the battery frame, and a nonlinear damping component is provided on the linear damping component. The battery pack is mounted on the nonlinear damping component.

[0008] Furthermore, the linear damping assembly includes four linear damping columns fixedly installed inside the battery box frame. Two sliding sleeves are symmetrically slidably fitted on the surface of each of the four linear damping columns. Two compression springs are symmetrically fitted on the surface of each of the four linear damping columns. One end of the compression spring is fixedly connected to one end of the corresponding sliding sleeve, and the other end of the compression spring is fixedly connected to a side wall adjacent to the battery box frame. Two linear damping frames are symmetrically arranged inside the battery box frame. The side walls of the two linear damping frames are respectively fixedly connected to the surfaces of the two corresponding sliding sleeves. The nonlinear damping assembly is installed on the two linear damping frames.

[0009] Furthermore, the nonlinear damping component includes two hangers, each fixed to the top of two linear damping frames. Each hanger has a mounting base fixed to its surface, and each mounting base has a bearing seat assembly fixed to its surface. A fixed shaft is mounted on each bearing seat assembly. A coil spring is sleeved on the surface of each fixed shaft, with one end of the coil spring fixedly connected to the corresponding fixed shaft surface. A U-shaped block is fixed to the surface of each mounting base, with an adjusting screw threaded to the bottom of the U-shaped block. The other end of the coil spring is located inside the U-shaped block and is pressed and fixed within it by the adjusting screw. An offset turntable is sleeved and fixed to the ends of each fixed shaft. A crank is rotatably mounted at the eccentric position of each offset turntable via a pin. A nonlinear damping frame is rotatably mounted at the bottom end of each crank via a pin. A support seat is connected to the bottom end of each nonlinear damping frame via a pin, and the battery pack is mounted on top of the support seat.

[0010] Furthermore, Z-shaped brackets are fixed to both sides of the nonlinear damping frame, and pulleys are installed at both ends of the Z-shaped brackets. A groove is opened in the middle of the pulley, and the linear damping frame is engaged in the groove of the corresponding two pulleys.

[0011] Furthermore, the battery pack is fixedly mounted on the support by screws.

[0012] Furthermore, four support blocks are symmetrically fixedly installed at the bottom of the battery box shell.

[0013] Furthermore, the hanger has a triangular structure and is welded and fixed to the top of the linear shock absorber.

[0014] Furthermore, the nonlinear damping frame has an inverted U-shaped structure.

[0015] Compared with the prior art, the present invention provides an adjustable nonlinear vibration-damping energy storage battery, which has the following beneficial effects: This invention, by incorporating linear and nonlinear damping components, provides effective protection for the battery pack. The two nonlinear damping frames within the nonlinear damping component, along with the coil spring, offset turntable, and crank, constitute a dual-end damping system for the battery pack, further enhancing the overall damping effect and structural stability. In this invention, the crank drives the offset turntable to rotate, causing the reverse force generated by the coil spring to exhibit nonlinear damping characteristics, effectively attenuating vibration energy at different frequencies. Furthermore, the U-shaped block and adjusting screw allow for adjustment of the coil spring's coiling degree, thereby adjusting the preload and accommodating battery packs of varying weights.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0019] like Figure 1-8 As shown, an adjustable nonlinear damping energy storage battery according to one embodiment of the present invention includes a battery pack 1, a battery frame 2, and a battery housing 3. The battery housing 3 is sleeved and fixed on the outside of the battery frame 2. Four support blocks are symmetrically fixedly installed on the bottom of the battery housing 3. A linear damping component 4 is provided inside the battery frame 2. A nonlinear damping component 5 is provided on the linear damping component 4. The battery pack 1 is installed on the nonlinear damping component 5.

[0020] like Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, in this embodiment, the linear damping assembly 4 includes four linear damping columns 401 fixedly installed inside the battery box frame 2. Two sliding sleeves 402 are symmetrically slidably fitted on the surface of each of the four linear damping columns 401. Two compression springs 403 are symmetrically fitted on the surface of each of the four linear damping columns 401. One end of the compression spring 403 is fixedly connected to one end of the corresponding sliding sleeve 402, and the other end of the compression spring 403 is fixedly connected to a side wall adjacent to the battery box frame 2. Two linear damping frames 404 are symmetrically arranged inside the battery box frame 2. The two side walls of the two linear damping frames 404 are respectively fixedly connected to the surfaces of the two corresponding sliding sleeves 402. The nonlinear damping assembly 5 is installed on the two linear damping frames 404.

[0021] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, the nonlinear damping component 5 includes two hangers 501, which are triangular in structure. The two hangers 501 are welded and fixed to the tops of two linear damping frames 404. Mounting seats 502 are fixed to the surfaces of both hangers 501, and bearing seat assemblies 503 are fixed to the surfaces of both mounting seats 502. Fixed shafts 504 are mounted on the bearing seat assemblies 503. Coil springs 505 are sleeved on the surfaces of both fixed shafts 504, with one end of each coil spring fixedly connected to the surface of the corresponding fixed shaft 504. U-shaped blocks 513 are fixed to the surfaces of both mounting seats 502. Adjusting screws 510 are threaded to the bottom of each U-shaped block 513, and the other end of the coil spring 505 is located inside the U-shaped block 513 and is pressed and fixed to the U-shaped block 513 by the adjusting screws 510. Inside, offset turntables 506 are fixedly fitted to the ends of two fixed shafts 504. Crank rods 507 are rotatably mounted at the eccentric positions of the two offset turntables 506 via pins. Nonlinear damping frames 508 are rotatably mounted at the bottom ends of the two crank rods 507 via pins. The nonlinear damping frames 508 have an inverted U-shaped structure. Support seats 509 are connected to the bottom ends of the two nonlinear damping frames 508 via pins. The battery pack 1 is fixedly mounted on the top of the support seat 509 by screws. Z-shaped brackets 511 are fixed to both sides of the nonlinear damping frame 508. Pulleys 512 are installed at both ends of the Z-shaped brackets 511. A groove is opened in the middle of the pulley 512. The linear damping frame 404 is engaged in the grooves of the corresponding two pulleys 512. This is to enable the nonlinear damping frame 508 to move stably in the vertical direction.

[0022] The working principle of this invention is as follows: During use, when the battery pack 1 is subjected to external vibration or impact, when the battery pack 1 moves vertically, it drives the nonlinear damping frame 508 to move vertically. The nonlinear damping frame 508 drives the crank 507 to move, which in turn drives the offset turntable 506 to rotate. The offset turntable 506 then drives the fixed shaft 504 to rotate, causing the fixed shaft 504 to tighten or loosen the coil spring 505. The coil spring 505 then generates a reverse torque. Due to the eccentric design of the offset turntable 506, the reverse torque generated by the coil spring 505 does not change linearly, but rather forms a nonlinear damping characteristic, which can effectively attenuate vibration energy of different frequencies. When the battery pack 1 moves horizontally, the hanger 501 drives the linear damping frame 404 in the water... Moving in the horizontal direction, the linear damping frame 404 will drive the corresponding sliding sleeve 402 to move on the linear damping column 401, thereby compressing and stretching the corresponding compression spring 403, which can attenuate the vibration energy. It should be further explained that when the initial preload of the coil spring 505 needs to be adjusted to adapt to battery packs 1 of different weights, the coiling degree of the coil spring 505 can be adjusted by rotating the adjusting screw 510 on the U-block 513, thereby adjusting the preload of the coil spring 81. When the weight of the battery pack 1 changes, the offset turntable 506 can still provide a suitable initial tension to the nonlinear damping frame 508 through the crank 507, ensuring that the entire damping system is always in the best working state and effectively meeting the usage needs of battery packs 1 of different weights in vibration environments.

[0023] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
