Description

Technical Field

[0001] This utility model relates to the field of new energy battery casing structure technology, and in particular to a combined battery casing end cap. Background Technology

[0002] With the continuous development of new energy battery technology, new energy batteries are becoming increasingly common in daily life, bringing great convenience. For example, electric vehicles use replaceable lithium batteries, and portable energy storage power supplies all encapsulate battery packs within protective casings to prevent damage from external physical impacts. Currently, battery casings are typically assembled from a main shell and end caps, with the handle usually integrated with the end cap for added strength. The edges of the end caps and the handles are high-risk points for impact damage and are prone to failure. Replacing damaged end caps requires replacing the entire end cap, resulting in high costs. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to design a modular battery casing end cap, which is assembled from multiple components, making it easy to disassemble and replace and reducing usage and maintenance costs.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A modular battery casing end cap is designed, comprising an upper cover and a handle disposed on the upper cover. The handle includes a first handle connected to the upper cover and a second handle that covers the first handle and engages with the upper cover. A step is provided on the periphery of the upper cover, and a snap-fit ​​groove is provided on the vertical sidewall of the step. The second handle includes a handle portion that covers the first handle and a step cover plate that covers the step. The step cover plate is provided with a plurality of buckles that can be embedded in the snap-fit ​​groove. The step is provided with a plurality of unlocking ports that are opposite to the buckles. The unlocking ports are used for external tools to be inserted to release the snap-fit ​​state between the buckles and the snap-fit ​​groove.

[0006] This design features a modular battery casing end cap assembled from multiple components, replacing the conventional one-piece casing end cap design and solving the problem of high replacement costs after damage. The main body of the casing end cap is the top cover, with a detachable handle attached. Specifically, the handle consists of a first handle and a second handle. The first handle is mounted on the top cover, while the second handle includes a handle portion and a stepped cover plate. After the stepped cover plate and step are engaged, the handle portion of the second handle and the first handle are integrated. If the handle is subjected to external impact, only the first or second handle may be damaged; in this case, only the damaged component needs to be replaced. The step is located around the perimeter of the top cover. After the stepped cover plate and step are engaged, the stepped cover plate protects the edge of the top cover. When the edge of the end cap is subjected to external impact, the stepped cover plate absorbs the impact force, acting as a buffer to protect the top cover and prevent damage to the edge. In this case, only the second handle needs to be replaced. Because the step cover plate and the step are assembled using a snap-fit ​​structure, it is difficult to separate them when replacing parts. By designing an unlocking port, an external tool can be inserted into the unlocking port to easily pry the buckle away from the snap-fit ​​groove, thereby separating the step cover plate from the step and achieving easy disassembly.

[0007] Furthermore, the first handle includes a connecting part connected to the upper cover, and a positioning groove is provided at the horizontal bottom of the step, with one end of the connecting part embedded in the positioning groove.

[0008] When assembling the handle and the top cover, the first handle and the top cover are assembled first. By setting a positioning groove on the top cover to restrict the assembly position of the first handle, the misalignment of the two during fixed connection is avoided, simplifying the assembly difficulty.

[0009] Furthermore, the positioning groove is provided with a positioning post and a first through hole, and the end face of the connecting part is provided with a positioning hole and a second through hole. When the connecting part is embedded in the positioning groove, the positioning post is inserted into the positioning hole, and the first through hole and the second through hole are connected.

[0010] To further ensure the assembly accuracy of the first handle and the top cover, a positioning post is set in the positioning groove, and a positioning hole is provided in the connecting part of the first handle. When the connecting part is placed into the positioning groove, the positioning post can be inserted into the positioning hole, which further limits the assembly error and allows the first through hole and the second through hole to be accurately aligned.

[0011] Furthermore, it also includes a threaded connector, wherein the first through hole is a threaded hole, and the threaded connector passes through the second through hole and is locked to the threaded hole.

[0012] The first handle is connected to the top cover by a threaded locking connection. The first through hole is a threaded hole. After the threaded hole and the second through hole are aligned, the threaded connector is locked to the threaded hole by a locking tool. The connection method is simple and efficient.

[0013] Furthermore, a slide is provided on the side of the connecting part opposite to the handle part, and the handle part is provided with a slider. When the first handle and the second handle are assembled together, the slider slides along the slide.

[0014] After the first handle and the top cover are assembled, the second handle is installed onto the first handle and snapped into place with the top cover. To reduce the difficulty of closing the cover, the first and second handles are equipped with guide structures. Specifically, the connecting part of the first handle is equipped with a slide rail, and the handle part of the second handle is equipped with a slider. During assembly, the slider is engaged in the slide rail, thus playing a sliding guide role during assembly. This allows the first and second handles to be aligned when closed, as well as the stepped cover plate to be aligned with the step of the top cover.

[0015] Furthermore, the step cover plate is disposed on the step, the step cover plate is flush with the upper surface of the upper cover, and the step cover plate is flush with the side surface of the upper cover.

[0016] After the step cover is installed on the step, the top surface and sides of the step cover are flush with the top cover, so that the two form an integrated structure, making the appearance simpler and more beautiful.

[0017] Furthermore, the top cover is rectangular, and the steps on at least two adjacent sides of the top cover are provided with the unlocking opening.

[0018] The unlocking ports can be set according to the actual situation. The top cover is rectangular, and unlocking ports are set on the steps of at least two adjacent sides of the top cover. In this way, when disassembling, the latches on the two adjacent sides of the top cover can be unlocked through the unlocking ports, and then the latches on the other two sides can be opened.

[0019] Furthermore, the upper surface of the cover is provided with a downwardly recessed groove, which is located below the handle.

[0020] By incorporating grooves, the grip space is increased, which allows for a reduction in the height of the handle, thereby decreasing the volume of the end cap and resulting in a more compact overall structure.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This design features a modular battery casing end cap assembled from multiple components, replacing the conventional one-piece casing end cap design and solving the problem of high replacement costs after damage. The main body of the casing end cap is the top cover, with a detachable handle attached. Specifically, the handle consists of a first handle and a second handle. The first handle is mounted on the top cover, while the second handle includes a handle portion and a stepped cover plate. After the stepped cover plate and step are engaged, the handle portion of the second handle and the first handle are integrated. If the handle is subjected to external impact, only the first or second handle may be damaged; in this case, only the damaged component needs to be replaced. The step is located around the perimeter of the top cover. After the stepped cover plate and step are engaged, the stepped cover plate protects the edge of the top cover.

[0029] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0030] like Figures 1 to 5 As shown, this embodiment provides a combined battery casing end cap, including an upper cover 1 and a handle 2 disposed on the upper cover 1. The upper cover 1 is rectangular, and the shape of the handle 2 is not limited. Of course, in other embodiments, the shape of the upper cover 1 may be other shapes. The handle 2 includes a first handle 21 connected to the upper cover 1 and a second handle 22 that covers the first handle 21 and engages with the upper cover 1. The upper cover 1 has continuous steps 11 around its perimeter, and the vertical sidewalls of the steps 11 have engaging grooves 12. The second handle 22 includes a handle portion 221 that covers the first handle 21 and a step cover plate 222 that covers the steps 11. The step cover plate 222 has several buckles 223 that can be embedded in the engaging grooves 12. In this embodiment, the engaging grooves 12 are continuous slots, or they can be designed as slots that correspond one-to-one with the buckles 223. The step 11 is provided with several unlocking ports 13 opposite to the latches 223. The unlocking ports 13 are used to allow external tools to be inserted to release the latches 223 from the latching grooves 12. The unlocking ports 13 can be set according to the actual situation. At least two adjacent sides of the step 11 of the top cover 1 are provided with unlocking ports 13. In this way, during disassembly, the latches 223 on the two adjacent sides of the top cover can be unlocked through the unlocking ports 13, and then the latches 223 on the other two sides can be opened.

[0031] The combined battery casing end cap provided in this embodiment is assembled from multiple components, replacing the conventional one-piece casing end cap design and solving the problem of high replacement costs after damage to the casing end cap. The main body of the casing end cap is the upper cover 1, and the handle 2 is detachably installed on the upper cover 1. Specifically, the handle 2 is assembled from a first handle 21 and a second handle 22. The first handle 21 is installed on the upper cover 1, and the second handle 22 includes a handle portion 221 and a stepped cover plate 222. After the stepped cover plate 222 is engaged with the step 11, the handle portion 221 of the second handle 21 is fastened to the first handle 21 to form a whole. If the handle is subjected to external impact, only the first handle 21 or the second handle 22 may be damaged. In this case, only the damaged part needs to be replaced. Step 11 is located on the periphery of the upper cover 1. After the step cover plate 222 is snapped into place with the step 11, the step cover plate 222 protects the edge of the upper cover 1. When the edge of the end cover is impacted by external force, the step cover plate 222 absorbs the impact force and acts as a buffer to protect the upper cover 1, preventing damage to the edge of the upper cover 1. At this time, only the second handle 22 needs to be replaced. Since the assembly of the step cover plate 222 and the step adopts a snap-fit ​​structure, it is difficult to separate them when replacing parts. By designing an unlocking port 13, an external tool can be inserted into the unlocking port 13 to easily pry the buckle 223 away from the snap-fit ​​groove 12, thereby separating the step cover plate 222 from the step 11, achieving the effect of easy disassembly.

[0032] like Figure 2 , Figure 4 and Figure 5 As shown, the first handle 21 includes a connecting part 211 connected to the upper cover 1. A positioning groove 14 is provided at the horizontal bottom of the step 11, and one end of the connecting part 211 is embedded in the positioning groove 14. When the handle 21 is assembled with the upper cover 1, the first handle 21 and the upper cover 1 are assembled first. By setting the positioning groove 14 on the upper cover 1 to restrict the assembly position of the first handle 21, the misalignment during the fixed connection is avoided, simplifying the assembly difficulty. In order to further ensure the assembly accuracy of the first handle 21 and the upper cover 1 and limit the assembly error, a positioning post 141 and a first through hole 142 are provided in the positioning groove 14. The end face of the connecting part 211 is provided with a positioning hole 213 and a second through hole 214. When the connecting part 211 is embedded in the positioning groove 14, the positioning post 141 is inserted into the positioning hole 213, and the first through hole 142 and the second through hole 214 are connected. The first through hole 142 can be a threaded hole. After the threaded hole is aligned with the second through hole 214, the threaded connector 3 is locked to the threaded hole by a locking tool. The first handle 21 is connected to the top cover 1 by a threaded locking connection, which is simple and efficient.

[0033] like Figure 2 and Figure 3As shown, a slide 212 is provided on the side of the connecting part 211 opposite to the handle part 221, and a slider 224 is provided on the handle part 221. When the first handle 21 and the second handle 22 are assembled together, the slider 224 slides along the slide 212 for guidance. After the first handle 21 is assembled with the upper cover 1, the second handle 22 is installed onto the first handle 21 and snapped into place with the upper cover 1. To reduce the difficulty of closing the cover, the first handle 21 and the second handle 22 are provided with a guide structure, that is, the connecting part 211 of the first handle 21 is provided with a slide 212, and the handle part 221 of the second handle 22 is provided with a slider 224. During assembly, the slider 224 is snapped into the slide 212, thereby playing a sliding guiding role during assembly, which can realize the alignment of the first handle 21 and the second handle 22 when they are closed, as well as the alignment of the stepped cover plate 222 with the step 11 of the upper cover 1.

[0034] like Figure 1 As shown, a step cover plate 222 is placed on the step 11, flush with the upper surface of the upper cover 1 and with the side surface of the upper cover 1. After the step cover plate 222 is placed on the step 11, it is flush with both the upper surface and side surface of the upper cover 1, forming a unified structure with a simpler and more aesthetically pleasing appearance. The upper surface of the upper cover 1 has a downwardly recessed groove 15 located below the handle 2. By providing the groove 15, the grip space is increased, allowing for a reduction in the height of the handle 2 and thus a smaller end cap volume, resulting in a more compact overall structure.
