Therefore, protecting lithium batteries during transportation is of paramount importance.

[0004] Existing lithium battery energy storage backup devices easily generate a large force on the battery casing when fixing the backup battery. This force causes the battery casing to be compressed and deformed. With long-term vibration and extended use time, the stability and integrity of the battery structure are affected.

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] See also Figure 1 , the lithium battery energy storage backup power device provided by the present invention is now described. The lithium battery energy storage backup power device includes: a base plate 1, a protective cover 4, a plurality of bolts and a plurality of suction cups 5. The protective cover 4 is arranged above the base plate 1 and is open at the bottom; a clearance hole for making way for the battery interface is opened on the side wall of the protective cover 4; the protective cover 4 is used to be buckled on the outside of the battery. A plurality of bolts are connected between the protective cover 4 and the base plate 1. A plurality of suction cups 5 are fixed on the inner side of the protective cover 4, and the suction cups 5 are used to be adsorbed on the battery shell; the plurality of suction cups 5 are used to position the battery and cushion the impact of the battery on the protective cover 4.

[0027] The lithium battery energy storage and backup device provided by the present invention has the following advantages: Compared with the prior art, the protective cover 4 of the present invention is disposed above the base plate 1 with an open bottom, and is buckled onto the outside of the battery. Multiple bolts connect the protective cover 4 to the base plate 1. Multiple suction cups 5 are fixed to the inside of the protective cover 4.

[0028] In actual use, the suction cup 5 is used to adhere to the battery housing; multiple suction cups 5 are used to position the battery. In this application, multiple suction cups 5 are used to position the battery, and multiple suction cups 5 can buffer the impact of the battery on the protective cover 4, ultimately avoiding a large force on the battery housing when positioning the battery, ensuring the integrity and stability of the battery structure.

[0029] In some embodiments of the lithium battery energy storage backup device provided in this application, please refer to Figure 1, a buffer pad 2 is provided on the upper surface of the base plate 1. It should be pointed out that the lithium battery itself has a certain mass, and will be affected by the external environment and produce vibrations during daily use, which causes the battery to have a strong impact force on the base plate 1, and this impact force will cause instability of the entire battery. Based on the above reasons, a buffer pad 2 is provided on the base plate 1. On the one hand, the buffer pad 2 can fill the gap between the base plate 1 and the battery, thereby ensuring that the protective cover 4 can effectively abut and position the battery. On the other hand, the buffer pad 2 can reduce the impact strength of the battery on the base plate 1, thereby maintaining stability, and the friction coefficient of the surface of the buffer pad 2 is also relatively high, which has a certain anti-slip effect.

[0030] In some embodiments of the lithium battery energy storage backup device provided in this application, please refer to Figure 1 The suction cup 5 includes a disc body 501 and a connecting post 502. The disc body 501 is used to be adsorbed on the battery shell, and the connecting post 502 is fixed on the protective cover 4. For more detailed description, the suction cup 5 consists of two parts, wherein the suction cup 5 includes a disc body 501 and a connecting post 502. The disc body 501 is adsorbed on the outer surface of the battery, and one end of the connecting post 502 is fixed on the disc body 501 and the other end is positioned on the protective cover 4.

[0031] In some embodiments of the lithium battery energy storage backup device provided in this application, please refer to Figure 1 The plate 501 is made of a flexible material. The suction cup 5 in this application serves both to position the battery inside the protective cover 4 and to cushion vibrations. Due to the battery's inherent bulk, relative motion occurs between the battery, the base plate 1, and the protective cover 4 during operation of the power-consuming mechanism. By constructing the suction cup 5 from a material with a certain degree of elasticity, relative vibration between the battery and the protective cover 4 can be effectively mitigated.

[0032] In some embodiments, the connection post 502 needs to be able to change its position relative to the protective cover 4 to facilitate placement of the battery into the protective cover 4 and subsequent positioning of the battery.

[0033] In some embodiments of the lithium battery energy storage backup device provided in this application, please refer to Figure 1 The tray body 501 and the connecting post 502 are integrally formed. This integral molding effectively improves the connection strength between the tray body 501 and the connecting post 502, avoiding a series of problems such as cracks between the tray body 501 and the connecting post 502, and ensuring sufficient connection strength between the tray body 501 and the connecting post 502. There are multiple suction cups 5, which are spaced apart within the protective cover 4, with the ultimate goal of limiting the position of the battery in all directions.

[0034] In some embodiments of the lithium battery energy storage backup device provided in this application, please refer to Figure 1, the hardness of the disk body 501 is lower than the hardness of the connecting column 502. The disk body 501 needs to be adsorbed on the outer shell of the battery. In order to have a strong adsorption ability, the disk body 501 itself needs to have a certain deformation ability, because only in this way can it produce deformation on the outer surface of the battery and complete adsorption. The main function of the connecting column 502 is to ensure the stability of the position of the protective cover 4 relative to the battery, that is, to achieve the positioning of the disk body 501, and the change of the position of the disk body 501 needs to be achieved through the inner connecting column 502. Based on the above reasons, the connecting column 502 itself needs to have a certain hardness to ensure operability. Under normal circumstances, the hardness of the connecting column 502 is close to that of a rigid material part.

[0035] In some embodiments of the lithium battery energy storage backup device provided in this application, please refer to Figure 1 , a connecting sleeve 8 is mounted on the connecting column 502, and the connecting column 502 only has the freedom to rotate around its own circumference; the connecting sleeve 8 is threadedly connected to the protective cover 4 to drive the connecting column 502 to move. When the battery is not placed in the protective cover 4, it is necessary to be able to move the disk body 501 through the connecting column 502 to make room. After the battery is placed in the protective cover 4, it is necessary to move the entire suction cup 5 toward the battery to complete the adsorption of the battery. In order to achieve the above-mentioned technical features, a connecting sleeve 8 is mounted on the connecting column 502, and the connecting sleeve 8 can drive the connecting column 502 to move relative to the protective cover 4, that is, it can change the position of the connecting sleeve 8 relative to the protective cover 4.

[0036] To this end, the connecting sleeve 8 is sleeved on the connecting column 502, and the connecting sleeve 8 only has the freedom of rotation relative to the connecting column 502. At the same time, the connecting sleeve 8 is threadedly connected to the protective cover 4. When the connecting sleeve 8 is rotated, the connecting sleeve 8 will squeeze the connecting column 502, and the connecting column 502 will drive the disk body 501 to move after being compressed.

[0037] In some embodiments of the lithium battery energy storage backup device provided in this application, please refer to Figure 1 , the connecting sleeve 8 is rotated and sleeved on the connecting column 502, and a limiting plate 6 is fixed to the end of the connecting sleeve 8 away from the disk body 501, and the limiting plate 6 is against the end face of the connecting column 502. For more detailed explanation, a limiting plate 6 is fixed to the end of the connecting sleeve 8 away from the disk body 501. The limiting plate 6 is fixed on the connecting sleeve 8, and the limiting plate 6 is against the end face of the connecting column 502. The limiting plate 6 and the connecting sleeve 8 form a structure similar to a cup. When the connecting sleeve 8 rotates relative to the protective cover 4, due to the presence of threads between the two, the connecting sleeve 8 will move away from or closer to the direction of the battery, and at the same time, the connecting column 502 can be driven to move through the limiting plate 6, thereby completing the adsorption and removal of the disk body 501.

[0038] When the battery needs to be removed, a lifter can be inserted through the through-holes provided on the bottom plate 1 and the protective cover 4 to allow air to enter between the disc body 501 and the battery.

[0039] In some embodiments of the lithium battery energy storage backup device provided in this application, please refer to Figure 1 The outer side of the limiting plate 6 is provided with a polygonal column 7. To effectively drive the limiting plate 6 and the connecting sleeve 8 to rotate, the polygonal column 7 is fixed to the limiting plate 6 and engages with a corresponding tool. When the polygonal column 7 is driven to rotate, the connecting sleeve 8 rotates, and the rotation of the connecting sleeve 8 ultimately drives the connecting column 502 to move.

[0040] In some embodiments of the lithium battery energy storage backup device provided in this application, please refer to Figure 1 The bottom edge of the protective cover 4 is fixed with multiple connecting blocks 3. Bolts penetrate the connecting blocks 3 and the base plate 1, and nuts are connected to the bottom ends of the bolts. When the battery is placed in the protective cover 4, the bottom edge of the protective cover 4 is separated from the base plate 1 by a certain distance. At this time, the bolts penetrate the connecting blocks 3 and the base plate 1, and the bottom ends of the bolts are located below the base plate 1. The protective cover 4 is positioned between the base plate 1 by tightening the nuts.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
