Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing technology, and in particular relates to an integrated cell structure. Background Technology

[0002] An integrated battery cell is a highly integrated battery unit design that compactly encapsulates electrodes, separators, electrolytes, and management modules (such as BMS chips), optimizing space and performance. Applications include battery packs for new energy vehicles, energy storage systems, and portable devices.

[0003] Most existing integrated battery cells are installed by welding when assembled, which makes maintenance inconvenient when a single integrated battery cell is damaged. Some integrated battery cells require external kits for installation and fixation when assembled, which is relatively troublesome during disassembly and maintenance and affects work efficiency. Therefore, we have improved the above-mentioned existing technologies based on actual usage. Utility Model Content

[0004] This invention overcomes the shortcomings of the prior art by providing an integrated battery cell structure to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An integrated battery cell structure includes an integrated battery cell housing, a power-conducting unit, and a lower terminal post. The top of the integrated battery cell housing is provided with an upper fixing sleeve, and the inner wall of the upper fixing sleeve is provided with two sets of guide grooves. The bottom of the integrated battery cell housing is provided with a lower guide sleeve. Both outer walls of the lower guide sleeve are provided with connecting strips adapted to the guide grooves, and the front end connecting strip is provided with a slot. The outer wall of the upper fixing sleeve is provided with a disassembly and assembly component.

[0007] The assembly includes an arc-shaped box connected to the outer wall of the upper fixed sleeve. The assembly also includes a movable rod that slides through and is connected to the arc-shaped box. The arc-shaped box is provided with a locking strip connected by a slot. One end of the movable rod near the guide groove is fixed to the locking strip. The movable rod is provided with a locking hole. The outer wall of the arc-shaped box is provided with a locking structure connected to the locking hole.

[0008] In a preferred embodiment of this utility model, an elastic plate is fixedly connected to the outer wall of the movable rod, and two sets of telescopic rods are connected between the elastic plate and the inner wall of the arc-shaped box, with a compression spring sleeved on the outer wall of each set of telescopic rods.

[0009] In a preferred embodiment of the present invention, the locking structure includes a threaded cylinder fixedly connected to the outer wall of the arc-shaped box, the threaded cylinder having a threaded hole, and a positioning screw connected to the locking hole being threadedly connected to the threaded hole.

[0010] In a preferred embodiment of this utility model, the diameter of the lower guide sleeve is equal to the inner diameter of the upper fixed sleeve.

[0011] In a preferred embodiment of the present invention, a hand ring is fixedly connected to the outer wall of the positioning screw, and the outer wall of the hand ring is embedded with staggered protrusions.

[0012] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0013] This invention achieves the installation and docking of adjacent integrated battery cell housings by connecting the guide groove on the inner wall of the upper fixed sleeve with the connecting strip on the outer wall of the lower guide sleeve. Pulling the moving rod on the disassembly assembly moves the elastic plate, and with the elasticity of the telescopic rod and compression spring, the locking strip can connect or disengage with the locking groove in the connecting strip, enabling quick assembly and disassembly of the upper fixed sleeve and lower guide sleeve, and thus adjacent integrated battery cell housings. This facilitates later maintenance and eliminates the need for external kits, improving work efficiency. Rotating the positioning screw on the locking structure allows it to connect with the locking hole, locking the position of the moving rod and improving the stability of the installation of adjacent integrated battery cell housings.

[0019] The following drawings will disclose several embodiments of this utility model. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these physical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0020] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0021] Combination Figures 1 to 3 As shown, this embodiment provides an integrated battery cell structure, including an integrated battery cell housing 10, a power-conducting unit 11, and a lower terminal post 14. The top of the integrated battery cell housing 10 is provided with an upper fixing sleeve 12, and the inner wall of the upper fixing sleeve 12 is provided with two sets of guide grooves 13. The bottom of the integrated battery cell housing 10 is provided with a lower guide sleeve 15. The outer walls on both sides of the lower guide sleeve 15 are provided with connecting strips 16 that are adapted to the guide grooves 13, and the front end connecting strip 16 is provided with a slot 17. The outer wall of the upper fixing sleeve 12 is provided with a disassembly and assembly component 20.

[0022] The assembly 20 includes an arc-shaped box 21 connected to the outer wall of the upper fixed sleeve 12. The arc-shaped box 21 is provided with a card strip 24 connected to the card slot 17. The moving rod 22 is provided with a card hole 27. The outer wall of the arc-shaped box 21 is provided with a locking structure 30 connected to the card hole 27.

[0023] The integrated cell housing 10 is an existing component. When adjacent integrated cell housings 10 are connected in series, they can be energized through the connection between the energizing unit 10 and the lower terminal post 14. The upper fixing sleeve 12 and the lower guide sleeve 15 are both fixedly connected to the integrated cell housing 10. When adjacent integrated cell housings 10 are connected in series, the installation and docking of adjacent integrated cell housings 10 are achieved through the connection between the guide groove 13 on the inner wall of the upper fixing sleeve 12 and the connecting strip 16 on the outer wall of the lower guide sleeve 15. Through the action of the disassembly and assembly component 20, the locking strip 24 can be connected to the connecting strip. The slot 17 inside the 16 connects the upper fixing sleeve 12 and the lower guide sleeve 15 for quick installation. During disassembly, the disassembly and assembly component 20 disengages the clip 24 from the slot 17, and the lower guide sleeve 15 can then disengage from the upper fixing sleeve 12. This enables quick disassembly and assembly of adjacent integrated cell housings 10, facilitating later maintenance and eliminating the need for external kits, thus improving work efficiency. The locking structure 30 can lock the position of the clip 24 (when installed in the slot 17), improving the stability of the installation of adjacent integrated cell housings 10.

[0024] The disassembly and assembly component 20 also includes a movable rod 22 that slides through the arc-shaped box 21. The end of the movable rod 22 near the guide groove 13 is fixedly connected to the clip 24. An elastic plate 23 is fixedly connected to the outer wall of the movable rod 22. Two sets of telescopic rods 25 are connected between the elastic plate 23 and the inner wall of the arc-shaped box 21. Each set of telescopic rods 25 has a compression spring 26 on its outer wall.

[0025] When installing adjacent integrated battery cell housings 10, the moving rod 22 is pulled outward to move the elastic plate 23 outward, allowing the retaining strip 24 to be housed in the inner cavity of the arc-shaped box 21. At this time, the telescopic rod 25 and the compression spring 26 are in a compressed state. Then, the lower guide sleeve 15 on the integrated battery cell housing 10 is installed in the upper fixed sleeve 12 on another set of integrated battery cell housings 10, and the connecting strip 16 is connected to the guide groove 13. After installation, the moving rod 22 is released, and the compressed telescopic rod 25 and the compression spring 26 automatically return to their original positions, causing the elastic plate 23 to slide towards the guide groove 13. The retaining strip 24 moves and connects with the retaining groove 17, thus fixing the positions of the upper fixed sleeve 12 and the lower guide sleeve 15, completing the installation of adjacent integrated battery cell housings 10. When disassembling, the moving rod 22 is pulled outward to disengage the retaining strip 24 from the retaining groove 17. After the upper fixed sleeve 12 and the lower guide sleeve 15 are no longer restricted, the adjacent integrated battery cell housings 10 can be removed.

[0026] The locking structure 30 includes a threaded cylinder 31 fixed to the outer wall of the arc-shaped box 21. The threaded cylinder 31 has a threaded hole 32, and a positioning screw 33 connected to the locking hole 27 is threaded into the threaded hole 32. During the movement of the moving rod 22, the positioning screw 33 is at the upper end (not connected to the locking hole 27). When the locking strip 24 is connected to the locking groove 17, the locking hole 27 is aligned with the positioning screw 33. Rotating the positioning screw 33 causes it to move down and connect with the locking hole 27, which locks the moving rod 22 and prevents the locking strip 24 from disengaging from the locking groove 17, thus improving the stability of the installation of adjacent integrated battery cell housings 10.

[0027] The diameter of the lower guide sleeve 15 is equal to the inner diameter of the upper fixed sleeve 12.

[0028] The positioning screw 33 is fixedly connected to a hand ring 34 on its outer wall, and the outer wall of the hand ring 34 is embedded with staggered protrusions. The hand ring 34 facilitates the rotation operation of the positioning screw 33, and the staggered protrusions can increase the friction with the operator's hand, thereby improving the stability when rotating the positioning screw 33.

[0029] While the present invention has been described above with reference to various embodiments, it should be understood that many changes and modifications can be made without departing from the scope of the present invention. That is, the methods, systems, or devices discussed above are merely examples. Various configurations can be appropriately omitted, substituted, or added to various processes or components. For example, in alternative configurations, methods can be performed in a different order than described, and / or various stages can be added, omitted, and / or combined. Moreover, features described with respect to certain configurations can be combined in various other configurations. Different aspects and elements of the configuration can be combined in a similar manner. Furthermore, as technology develops, many elements are merely examples and do not limit the scope of this disclosure or the claims.

[0030] Specific details are provided in the specification to offer a thorough understanding of exemplary configurations, including implementations. However, configurations can be practiced without these specific details; for example, well-known circuits, processes, algorithms, structures, and techniques have been shown without unnecessary detail to avoid obscuring the configuration.

Rather, the foregoing description of the configurations will provide those skilled in the art with an enabling description for implementing the described techniques. Various changes can be made to the function and arrangement of the elements without departing from the spirit or scope of this disclosure.

[0031] Furthermore, although each operation can be described as a sequential process, many operations can be executed in parallel or simultaneously.
