Description

Technical Field

[0001] This utility model relates to the field of energy storage battery technology, and in particular to a buffer and shock-absorbing energy storage battery. Background Technology

[0002] Energy storage batteries are used to provide power for peak-shaving and frequency-regulating power auxiliary services, electric vehicles, electric trains, electric bicycles, golf carts, etc. Most energy storage battery devices do not need to be moved, so lithium batteries are used for energy storage. Different energy storage batteries have different requirements for different scenarios. Attention needs to be paid to issues such as expansion rate, energy density, and uniformity of electrode material performance in order to pursue long life and low cost of the entire energy storage device.

[0003] When energy storage batteries are used for power supply, they need to provide continuous power. When energy storage batteries are mounted on a movable carrier, collisions or bumps on the carrier will cause a certain impact force on the energy storage batteries, which can damage them and reduce their safety performance. Therefore, energy storage batteries need to have good strength and impact resistance to prevent damage from vibration.

[0004] Most existing energy storage batteries reduce the impact of collisions or bumps by using springs for shock absorption. A spring device is installed between the energy storage battery and the mounting carrier. When the carrier is hit by a collision or bump, the spring force can reduce the impact force. However, after long-term use, the spring force decreases, and collisions or bumps still occur between the energy storage battery and the carrier. A buffer and shock-absorbing energy storage battery needs to be designed to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as reduced spring force and the continued collision or bumping between the energy storage battery and the carrier, by proposing a buffer and shock-absorbing energy storage battery.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A shock-absorbing energy storage battery includes a battery and a base. The bottom of the battery has a mounting slot, and each of the four corners of the mounting slot is fixedly connected to a mounting base. A fixing post is provided on each of the left and right sides of the mounting slot. The front and rear ends of each fixing post are fixedly connected to the middle of the front and rear mounting bases, respectively. A movable frame is rotatably connected to the front side of the left fixing post and the rear side of the right fixing post. A sliding groove is provided on the inner left rear end and right front end of the base. The movable frame is slidably connected to the inner side of the corresponding sliding groove. A first spring is provided inside each sliding groove. Limit sleeves are slidably connected to the outer sides of each fixing post, and locking bolts are threaded to the middle of the outer sides of each limit sleeve.

[0008] Through the above technical solution, the battery presses down on the moving frame. Due to the limitation of the sliding groove, the bottom end of the moving frame slides inside the sliding groove, while the top end rotates outside the fixed column, causing the first spring to contract. The battery is buffered and damped, reducing the impact or bumps that could cause damage to the battery. This avoids the defect that after long-term use, the spring force decreases, resulting in collisions or bumps between the energy storage battery and the carrier.

[0009] Furthermore, each of the four corners of the bottom of the battery is fixedly connected to a sliding post, and each of the four corners of the inner side of the base is provided with a sliding sleeve. Each sliding sleeve is provided with a second spring inside, and the sliding posts are slidably connected to the inner side of the corresponding sliding sleeve.

[0010] The above technical solution uses a sliding column that slides inside the sliding sleeve to compress the second spring, thereby buffering and damping the vertical force generated by battery vibration and collision.

[0011] Furthermore, the movable frame is disposed opposite to each other at the bottom of the battery;

[0012] The above technical solution enables the bottom left and right ends of the battery to be supported in opposite directions, while the moving frame moves in the opposite direction, increasing the cushioning effect.

[0013] Furthermore, a first opening is provided at the bottom of the outermost end of the movable frame, and a second opening is provided at the outermost end of the sliding groove. The left and right ends of the first spring are respectively located inside the corresponding first and second openings.

[0014] The above technical solution facilitates the placement of the first spring by setting the first opening and the second opening, while preventing the first spring from falling off.

[0015] Furthermore, a limiting plate is fixedly connected to the middle of both the left and right sides of the battery, and a limiting groove is provided on the upper part of both the left and right sides of the base. The bottom end of the limiting plate is slidably connected to the inner side of the corresponding limiting groove.

[0016] By using the above technical solution, the battery will not fall off the base in the upward direction because the limiting plate slides inside the limiting groove.

[0017] Furthermore, the base is provided with fixing grooves at both the front and rear, and heat dissipation plates are fixedly connected inside the fixing grooves. Several fins are provided on the outer side of the heat dissipation plates.

[0018] The above technical solution uses a heat sink to contact the surface of the battery, dissipating the heat generated by the battery through fins, thus preventing the battery from being damaged by increased heat due to poor heat dissipation inside the base.

[0019] This utility model has the following beneficial effects:

[0020] In this invention, during installation, the fixed base, fixed column, movable frame, first spring, and second spring are installed at the battery and base placement positions. The base is then fixed onto the carrier. During use, when the carrier experiences collisions or bumps, the battery generates a downward force, pressing down on the movable frame. Due to the restriction of the sliding groove, the bottom end of the movable frame slides inside the groove, while the top end rotates outside the fixed column, causing the first spring to contract. Simultaneously, the sliding column slides inside the sliding sleeve, causing the second spring to contract. The limiting plate slides downward inside the limiting groove, and the first spring generates a horizontal force. The upward elastic force of the first spring and the vertical elastic force of the second spring buffer and dampen the downward force of the battery, reducing the damage caused by collisions or bumps. At the same time, the heat generated by the battery is dissipated through the fins by the heat sink in contact with the battery surface. Multiple springs buffer and dampen the energy storage battery in both horizontal and vertical directions, avoiding the defects of collisions or bumps between the energy storage battery and the carrier caused by the reduction of spring elasticity after long-term use. The structure is simple, easy to install and disassemble, and allows for the periodic replacement of the first and second springs to prevent spring damage. Attached Figure Description

[0029] Reference Figure 1-5 This utility model provides an embodiment of a buffer and shock-absorbing energy storage battery, including a battery 1 and a base 2. The bottom of the battery 1 is provided with a mounting groove 3, and a fixing seat 4 is fixedly connected to each of the four corners of the mounting groove 3. A fixing post 5 is provided on the left and right sides of the mounting groove 3. The front and rear ends of the fixing post 5 are respectively fixedly connected to the middle of the front and rear fixing seats 4. A movable frame 6 is rotatably connected to the front side of the left fixing post 5 and the rear side of the right fixing post 5. A sliding groove 7 is provided on the left rear end and right front end of the inner side of the base 2. The movable frame 6 is slidably connected to the inner side of the corresponding sliding groove 7. A first spring 8 is provided inside the sliding groove 7. A limiting sleeve 12 is slidably connected to the outer side of the fixing post 5. A locking bolt 13 is threadedly connected to the middle of the outer side of the limiting sleeve 12, which facilitates fixing the movable frame 6 in the fixed position of the fixing post 5 and prevents the bottom end of the movable frame 6 from falling into the inner side of the sliding groove 7. At the same time, the locking bolt 13 facilitates locking the limiting sleeve 12 to the fixing post 5, which is convenient for disassembling the movable frame 6.

[0030] Preferably, a sliding post 9 is fixedly connected to each of the four corners of the bottom end of the battery 1, and a sliding sleeve 10 is provided at each of the four corners of the inner side of the base 2. A second spring 11 is provided inside each of the sliding sleeves 10. The sliding post 9 is slidably connected to the inner side of the corresponding sliding sleeve 10. By sliding the sliding post 9 on the inner side of the sliding sleeve 10, the second spring 11 is compressed, so that the force generated by the vibration and collision of the battery 1 in the vertical direction is buffered and damped.

[0031] Preferably, the movable frame 6 is arranged opposite to each other at the bottom of the battery 1, which enables the left and right ends of the bottom of the battery 1 to support each other, while the movable frame 6 moves in opposite directions to increase the cushioning effect.

[0032] Preferably, the bottom of the outermost end of the movable frame 6 is provided with a first opening 14, and the outermost end of the sliding groove 7 is provided with a second opening 15. The left and right ends of the first spring 8 are respectively located inside the corresponding first opening 14 and second opening 15. The setting of the first opening 14 and the second opening 15 facilitates the placement of the first spring 8 and prevents the first spring 8 from falling off.

[0033] Preferably, a limiting plate 16 is fixedly connected to the middle of both the left and right sides of the battery 1, and a limiting groove 17 is provided on the upper part of both the left and right sides of the base 2. The bottom end of the limiting plate 16 is slidably connected to the inner side of the corresponding limiting groove 17. By sliding the limiting plate 16 on the inner side of the limiting groove 17, the battery 1 will not fall off the base 2 in the upward direction.

[0034] Preferably, the base 2 is provided with a fixing groove 18 at both the front and rear. A heat sink 19 is fixedly connected inside the fixing groove 18. Several fins 20 are provided on the outer side of the heat sink 19. The heat sink 19 contacts the surface of the battery 1 and dissipates the heat generated by the battery 1 through the fins 20, preventing the battery 1 from being damaged by increased heat due to poor heat dissipation inside the base 2.

[0035] Working principle: During installation, the fixed base 4, fixed column 5, movable frame 6, first spring 8 and second spring 11 are installed at the placement positions of battery 1 and base 2. Then, base 2 is fixed on the carrier. During use, when the carrier is impacted or bumped, battery 1 generates a downward force, which presses down on movable frame 6. Due to the restriction of sliding groove 7, the bottom end of movable frame 6 slides inside sliding groove 7, and the top end rotates outside fixed column 5, causing first spring 8 to contract. At the same time, sliding column 9 slides inside sliding sleeve 10, causing second spring 11 to contract. Limiting plate 16 slides downward inside limiting groove 17. First spring 8 generates a horizontal elastic force, and second spring 11 generates a vertical elastic force, which buffers and dampens the downward force of battery, reducing the impact or bumps that could damage battery. At the same time, the heat dissipation plate 19 contacts the surface of battery 1, and the heat generated by battery 1 is dissipated through fins 20.
