Description

Technical Field

[0001] This utility model belongs to the field of battery technology, specifically a wide-temperature backup battery. Background Technology

[0002] With the rapid development of the energy storage industry, lithium batteries are also being widely used in the communications industry. Integrated base stations, edge stations, repeaters, macro base stations, and solar base stations in the communications industry all require corresponding energy storage systems to cope with various situations, with backup power supplies used to address power shortages. Wide-temperature lithium batteries are a common type of battery, capable of operating normally within a temperature range of -50℃ to 85℃, with some models (such as nickel-metal hydride batteries) even extending to -45℃ to 60℃. This wide adaptability makes them suitable for high-altitude, extremely cold, or high-temperature environments, making them one of the most advanced battery types currently available.

[0003] However, assembling backup battery modules requires sequentially installing multiple battery cells onto an assembly rack. Since most assembly racks use trapezoidal snap-fit ​​mechanisms, the alignment of these snap-fit ​​mechanisms requires manual inspection, making the assembly process cumbersome. Given the large number of battery cells in a battery module, this process is inconvenient for personnel, thus reducing assembly efficiency. To address these issues, we offer a wide-temperature backup battery. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a wide-temperature backup battery.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wide-temperature backup battery, comprising:

[0006] Two sets of opposing support mechanisms, each support mechanism comprising several assembly frames, each assembly frame having two sets of conical blocks fixed to its side and two sets of conical grooves provided therein, and the assembly frames being engaged with the conical blocks within the conical grooves of adjacent assembly frames, with a limit mechanism provided on the inner wall of each assembly frame.

[0007] The battery cells are arranged in multiple groups, with their two ends inserted into corresponding upper and lower assembly frames and limited by a limiting mechanism.

[0008] A support mechanism is provided between two sets of support mechanisms.

[0009] Preferably, the limiting mechanism includes circumferentially arranged partitions, each partition being fixedly connected to the inner wall of the assembly frame, and a limiting block being fixedly connected to one end of each partition. The surface of the assembly frame is slidably disposed on the surface of each partition, and the limiting block is in contact with one end of the assembly frame.

[0010] Preferably, the inner wall of the assembly frame is provided with circumferentially arranged through grooves, and the through grooves and partitions are intersected with each other. Arc-shaped grooves are provided at the four corners of the assembly frame.

[0011] Preferably, the support mechanism includes four support plates, which are located at the four corners of the two sets of bracket mechanisms. Each support plate has a protrusion fixed to both ends, and the protrusion is inserted into the corresponding through groove.

[0012] Preferably, each of the support plates is fixedly connected to an elastic clamp at the middle, and the elastic clamp is snapped onto the surface of the corresponding battery cell.

[0013] Preferably, the assembly frame has a clearance groove on the surface away from the battery cell.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the arrangement of assembly frames, conical blocks, partitions, conical grooves, and limiting blocks, utilizes the conical shape of the conical blocks and grooves. Therefore, when assembling each assembly frame, the conical bottom of the conical block can easily insert into the conical groove of the adjacent assembly frame, eliminating the need for precise observation of alignment between the conical block and groove. This allows for faster assembly of the various assembly frames. After two sets of assembly frames are assembled, each battery cell can be inserted between the corresponding two sets of assembly frames and limited by the partitions and limiting blocks, increasing overall drop resistance. Furthermore, one end of the battery cell does not contact the inner wall after insertion into the assembly frame, but only the partition, thus facilitating the dissipation of heat from one end of the battery cell through the gaps within the assembly frame.

[0016] 2. With the design of through slots and arc slots, the heat in the battery pack can be dissipated through the through slots and arc slots after the various assembly frames are assembled, thereby increasing the overall heat dissipation performance of the device.

[0017] 3. With the support mechanism, this utility model allows the support plate to be inserted into the corresponding upper and lower through slots via two protrusions after the battery cell is assembled through two sets of bracket mechanisms, thereby supporting the overall structure, ensuring overall stability and preventing it from falling apart.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this embodiment proposes a wide-temperature backup battery, comprising:

[0025] Two sets of opposing support mechanisms are provided. Each support mechanism includes several assembly frames 2. Two sets of conical blocks 8 and two sets of conical grooves 10 are fixed to the sides of each assembly frame 2. The assembly frame 2 is engaged with the conical grooves 10 of adjacent assembly frames 2 by the conical blocks 8. Since the conical blocks 8 and the conical grooves 10 are conical, the diameter of the bottom end of the conical block 8 is much smaller than the diameter of the top end of the conical groove 10. This allows two adjacent assembly frames 2 to be easily inserted into the conical grooves 10 by utilizing the conical shape of the bottom end of the conical block 8 during assembly. There is no need for personnel to accurately observe whether the conical block 8 and the conical groove 10 are aligned. This gives the conical block 8 the feature of automatic centering when inserted into the conical groove 10, which enables faster assembly of each assembly frame 2 and improves the assembly efficiency of the assembly frame 2. In addition, the length of the conical blocks 8 and the conical grooves 10 is half the length of the side of the assembly frame 2, which is more conducive to personnel operation. The inner wall of the assembly frame 2 is provided with a limit mechanism.

[0026] The battery cell 1 has its two ends inserted into the corresponding upper and lower assembly frames 2 and is limited by a limiting mechanism. The limiting mechanism can securely insert one end of the battery cell 1 into the assembly frame 2, which is beneficial for the subsequent assembly of the battery pack. The battery cells 1 are arranged in multiple groups.

[0027] The support mechanism is set between the two sets of bracket mechanisms. With the support mechanism set, after the battery cell 1 is assembled between the two sets of bracket mechanisms, the support mechanism supports the two sets of bracket mechanisms and prevents the two sets of bracket mechanisms from becoming loose. The mechanical parts and equipment in this device are all conventional models in the existing technology. In addition, the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0028] like Figure 3 As shown, the limiting mechanism includes circumferentially arranged partitions 9, each partition 9 is fixedly connected to the inner wall of the assembly frame 2, and a limiting block 11 is fixedly connected to one end of each partition 9. The surface of the assembly frame 2 is slidably disposed on the surface of each partition 9, and the limiting block 11 is in contact with one end of the assembly frame 2. With the above structure, one end of the battery cell 1 can be inserted into the assembly frame 2 without contacting the inner wall, but only in contact with the partition 9. Therefore, it is beneficial to dissipate the heat of one end of the battery cell 1 through the gap in the assembly frame 2. At the same time, the limiting block 11 also plays a limiting role for the battery cell 1, preventing the battery cell 1 from falling through the assembly frame 2. In addition, it prevents the battery cell 1 from sliding freely in the assembly frame 2. Anti-slip protrusions are provided on the surface of the partition 9 to increase the contact friction between the partition 9 and the battery cell 1.

[0029] like Figures 1 to 3 As shown, the inner wall of the assembly frame 2 is provided with circumferentially arranged through grooves 3, and the through grooves 3 and the partition 9 are intersected. The four corners of the assembly frame 2 are provided with arc grooves 4. With the above structure, when the assembly frames 2 are assembled together, the heat in the battery pack can be dissipated through the through grooves 3 and arc grooves 4, which is beneficial to the overall heat dissipation performance. Adjacent through grooves 3 can be interconnected.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, the support mechanism includes four support plates 6, which are located at the four corners of the two sets of bracket mechanisms. Each support plate 6 has a protrusion 12 fixed to both ends, and the protrusion 12 is inserted into the corresponding through slot 3. With the above structure, after the battery cell 1 is assembled by the two sets of bracket mechanisms, the support plate 6 can be inserted into the corresponding upper and lower through slots 3 through the two protrusions 12, thereby supporting the overall structure, ensuring the overall stability, preventing it from falling apart, and making the four support plates 6 located at the four corners of the overall structure. In addition, the setting of the support plates 6 will not affect the subsequent installation of the protection plate on the side of the battery pack.

[0031] like Figure 1 , Figure 2 and Figure 4As shown, each support plate 6 is fixedly connected to the middle of an elastic clamp 7, and the elastic clamp 7 is snapped onto the surface of the corresponding battery cell 1. With the setting of the elastic clamp 7, when the support plate 6 is in use, the elastic clamp 7 is directly snapped onto the corresponding battery cell 1, thereby ensuring the stability of the support plate 6 between the two sets of support mechanisms and preventing the support plate 6 from falling off between the two sets of support mechanisms.

[0032] like Figure 1 and Figure 2 As shown, the surface of the assembly frame 2 away from the battery cell 1 has a clearance groove 5. The clearance groove 5 facilitates the subsequent welding of nickel strips between the battery cells 1.

[0033] The working principle and usage process of this utility model are as follows: During assembly, the assembly frame 2 is first inserted into the conical groove 10 of the adjacent assembly frame 2 using the conical block 8. This eliminates the need for personnel to precisely observe whether the conical block 8 and the conical groove 10 are aligned, thus enabling faster assembly of the various assembly frames 2. After the upper and lower assembly frames 2 are assembled, each battery cell 1 is inserted into the lower assembly frame 2. Then, the upper assembly frame 2 is inserted and fixed to the top of each battery cell 1, thereby completing the overall assembly of the battery pack. This increases the overall drop resistance. Furthermore, one end of the battery cell 1 does not contact the inner wall after being inserted into the assembly frame 2, but only contacts the partition 9. This facilitates the dissipation of heat from one end of the battery cell 1 through the gaps in the assembly frame 2. At the same time, the limiting block 11 also limits the position of the battery cell 1. Finally, each support plate 6 is inserted into the corresponding upper and lower through slots 3 through two protrusions 12, thereby supporting the overall structure, ensuring overall stability, and preventing the structure from falling apart.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
