Description

Technical Field

[0001] This disclosure relates to the technical field of portable battery cases, and in particular to a battery assembly structure and battery case that are easy to assemble and disassemble. Background Technology

[0002] In the field of modern electronic devices, battery boxes, as key components that house battery packs and provide power to devices, are widely used in various products such as smart homes, portable electronic devices, power tools, and communication equipment. Their structural design directly affects the stability of battery installation, ease of replacement, and the overall lifespan of the device.

[0003] Currently, common battery boxes on the market typically use screws, welding, or a one-piece structure to connect the battery cover to the battery casing. Screw fixing requires tools like screwdrivers for disassembly and assembly, a cumbersome process, especially for devices that require frequent battery replacements. Repeated disassembly and assembly are not only time-consuming and labor-intensive but can also lead to stripped screws and worn threads, affecting the structural stability and sealing of the battery box. While welding or a one-piece structure ensures connection strength, it doesn't allow for individual battery pack replacement or repair. When the battery pack malfunctions, the entire battery box often needs to be replaced, increasing user costs and wasting resources. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a battery assembly structure that facilitates the disassembly and assembly of battery modules.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0006] A battery assembly structure that is easy to assemble and disassemble includes a housing, a top cover, and a battery module. The housing has a receiving groove, and the battery module is disposed in the receiving groove.

[0007] The easily detachable battery assembly structure also includes a switch component connected to the end of the battery module. The top cover has a limiting opening, the peripheral wall of which is located on the same side as the switch component, and the switch component is embedded in the limiting opening. The limiting opening has a protruding limiting boss, which has a first limiting groove and a second limiting groove. The switch component has a first protrusion and a second protrusion, the first protrusion correspondingly abutting against the first limiting groove, and the second protrusion correspondingly abutting against the second limiting groove.

[0008] In one embodiment, the housing is provided with a connecting portion located at the same end of the switch element, the connecting portion having a connecting cavity, the switch element having a protruding connecting post, and the connecting post being slidably disposed in the connecting cavity.

[0009] In one embodiment, the first limiting groove and the second limiting groove are disposed opposite to each other on the outer periphery of the limiting boss, and the length of the first limiting groove is equal to the length of the second limiting groove.

[0010] In one embodiment, the peripheral wall of the limiting port is provided with a platform, one end of the platform extends to the first limiting groove, the other end of the platform extends to the second limiting groove, and the outer peripheral edge of the protective member near the housing abuts the abutting surface.

[0011] In one embodiment, the first bump and the second bump are disposed opposite to each other on the outer periphery of the switch.

[0012] In one embodiment, the receiving groove is provided with a first fixing tube, a second fixing tube, a third fixing tube and a fourth fixing tube, and the top cover is provided with a first positioning post, a second positioning post, a third positioning post and a fourth positioning post on the side near the battery module. The first positioning post is correspondingly disposed on the first fixing tube, the second positioning post is correspondingly disposed on the first fixing tube, the second positioning post is correspondingly disposed on the second fixing tube, the third positioning post is correspondingly disposed on the third fixing tube, and the fourth positioning post is correspondingly disposed on the fourth fixing tube.

[0013] In one embodiment, the easily detachable battery assembly structure further includes a first battery retaining cover and a second battery retaining cover, which are spaced apart on the side of the upper cover near the battery module. The first battery retaining cover is attached to one side of the battery module, and the second battery retaining cover is attached to one side of the battery module.

[0014] In one embodiment, the easily detachable battery assembly structure further includes foam cotton, which is disposed between the battery module and the top cover.

[0015] In one embodiment, the easily detachable battery assembly structure further includes a first circuit board disposed on the inner peripheral wall of the receiving groove, and the first circuit board is electrically connected to one end of the battery module.

[0016] A battery case includes the battery assembly structure that is easy to assemble and disassemble as described in any of the above embodiments.

[0017] Compared with the prior art, this disclosure has at least the following advantages:

[0018] A receiving groove is provided in the housing to house the battery module. A switch is movably connected to the end of the housing, allowing it to swing relative to the housing. A limiting opening is provided in the top cover, with a limiting protrusion on the inner wall of the limiting opening. The limiting protrusion has a first limiting groove and a second limiting groove. Because the first protrusion abuts against the first limiting groove and the second protrusion abuts against the second limiting groove, the top cover will not shift relative to the housing. The switch is embedded in the limiting opening, preventing the top cover from shifting left or right relative to the housing due to the limiting opening and the switch, thus ensuring the top cover is stably placed on the end face of the housing. Because the switch is movably connected to the housing, when the switch moves away from the limiting opening, it causes the first and second protrusions to disengage from their corresponding first and second limiting grooves, separating the top cover from the housing. The installation, fixing, and disassembly of the housing and top cover are achieved through a switch, avoiding the need to use tools such as screwdrivers for disassembly and assembly. By setting the switch to be embedded in the limit port, it is convenient to quickly assemble and disassemble the top cover and housing of the battery pack. Attached Figure Description

[0030] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0031] like Figures 1 to 5 As shown, an embodiment of a battery assembly structure 10 that is easy to assemble and disassemble includes a housing 100, a top cover 200, a battery module 300, and a switch 400. The housing 100 has a receiving groove 120, and the battery module 300 is disposed in the receiving groove 120.

[0032] The switch 400 is movably connected to the end of the housing 100. The upper cover 200 covers the end face of the housing 100. The upper cover 200 has a limiting opening 210, which is located on the same side as the switch 400. The switch 400 is embedded in the limiting opening 210. The limiting opening 210 has a limiting boss 2110, which has a first limiting groove 2111 and a second limiting groove 2112. The switch 400 has a first protrusion 410 and a second protrusion 420. The first protrusion 410 abuts against the first limiting groove 2111, and the second protrusion 420 abuts against the second limiting groove 2112.

[0033] In this embodiment, a receiving groove 120 is provided in the housing 100, so that the battery module 300 is disposed in the receiving groove 120; at the same time, the switch 400 is movably connected to the end of the housing 100, so that the switch 400 can swing relative to the housing 100; a limiting opening 210 is provided in the upper cover 200, and a limiting boss 2110 is provided on the inner wall of the limiting opening 210. The limiting boss 2110 has a first limiting groove 2111 and a second limiting groove 2112. The upper cover 200 is supported by the first limiting groove 2111, and the second protrusion 420 is supported by the second limiting groove 2112, thus preventing the upper cover 200 from shifting relative to the housing 100. Simultaneously, the upper cover 200 has a limiting opening 210, in which the switch 400 is embedded, ensuring that the upper cover 200 does not shift left or right relative to the housing 100 under the limiting conditions of the limiting opening 210 and the switch 400. This allows the upper cover 200 to stably cover the end face of the housing 100. Because the switch 400 is movably connected to the housing 100, when the switch 400 moves away from the limiting opening 210, it causes the first protrusion 410 and the second protrusion 420 to disengage from their corresponding first limiting groove 2111 and second limiting groove 2112, causing the upper cover 200 to separate from the housing 100. The switch 400 is used to install, fix, and remove the housing 100 and the top cover 200, avoiding the need to use tools such as screwdrivers to complete the disassembly and assembly. By setting the switch 400 to be embedded in the limit port 210, it is convenient to quickly assemble and remove the top cover 200 and the housing 100 of the battery pack.

[0034] Combination Figure 1 and Figure 2As shown, in one embodiment, the housing 100 is provided with a connecting portion 110, which is located at the same end of the switching element 400. The connecting portion 110 has a connecting cavity 1110, and the switching element 400 has a protruding connecting post 430, which is slidably disposed in the connecting cavity 1110. It can be understood that the cooperation between the connecting portion 110 and the connecting post 430 provides a stable guiding structure for the movable connection of the switching element 400. The connecting cavity 1110 forms a circumferential limit on the connecting post 430, ensuring that the connecting post 430 can only slide along the extending direction of the connecting cavity 1110, thereby restricting the movement trajectory of the switching element 400 and ensuring that the switching element 400 does not experience lateral displacement or wobbling during operation. When the top cover 200 needs to be removed, the user pushes or pulls the switch 400, and the connecting post 430 slides smoothly along the connecting cavity 1110, causing the switch 400 to move as a whole, so that the first protrusion 410 and the second protrusion 420 accurately disengage from the first limiting groove 2111 and the second limiting groove 2112. When installing the top cover 200, the connecting post 430 slides in the opposite direction along the connecting cavity 1110, which can guide the first protrusion 410 and the second protrusion 420 to accurately engage with the corresponding limiting grooves, avoiding misalignment of the switch 400. This sliding fit structure enhances the stability and smoothness of the switch 400's movement, reduces jamming or sticking during operation, and further improves the ease of disassembly and assembly of the battery assembly structure.

[0035] See Figure 1 and Figure 2 In one embodiment, the first limiting groove 2111 and the second limiting groove 2112 are disposed opposite to each other on the outer periphery of the limiting boss 2110, and the length of the first limiting groove 2111 is equal to the length of the second limiting groove 2112. It can be understood that the opposite arrangement of the first limiting groove 2111 and the second limiting groove 2112 causes the first protrusion 410 and the second protrusion 420 to form symmetrical force-bearing points on the switch member 400. When the switch member 400 engages with the limiting boss 2110, the two protrusions can evenly apply a resisting force from both sides of the limiting boss 2110, preventing the upper cover 200 from tilting or loosening due to excessive force on one side, further enhancing the stability of the connection between the upper cover 200 and the housing 100.

[0036] See Figure 1 and Figure 2Furthermore, a platform 220 is provided on the peripheral wall of the limiting port 210. One end of the platform 220 extends to the first limiting groove 2111, and the other end extends to the second limiting groove 2112. The outer periphery of the protective member near the housing 100 abuts against the abutting surface. It can be understood that the platform 220 on the peripheral wall of the limiting port 210 connects the first limiting groove 2111 and the second limiting groove 2112 to form a continuous support structure, providing additional guidance and support for the movement of the switch member 400. When the switch member 400 drives the first protrusion 410 and the second protrusion 420 to slide within the first limiting groove 2111 and the second limiting groove 2112, the platform 220 can lift the bottom of the switch member 400, preventing the protrusions from tilting or jamming due to uneven force, ensuring that the switch member 400 always moves along a stable trajectory during assembly and disassembly, and improving the smoothness of operation.

[0037] See Figure 1 , Figure 2 and Figure 3 In one embodiment, the first protrusion 410 and the second protrusion 420 are disposed opposite each other on the outer periphery of the switch member 400. It is understood that the relative arrangement of the first protrusion 410 and the second protrusion 420 on the outer periphery of the switch member 400 precisely corresponds to the relative distribution of the first limiting groove 2111 and the second limiting groove 2112 on the limiting boss 2110, ensuring structural compatibility when the switch member 400 mates with the limiting opening 210. This symmetrical layout allows the two protrusions to simultaneously embed into their corresponding grooves, avoiding one-sided jamming or loosening caused by protrusion distribution misalignment, further improving the fitting accuracy. Simultaneously, the oppositely disposed protrusions can generate a balanced reaction force when the switch member 400 is subjected to force. When the user operates the switch 400 for assembly or disassembly, external force is transmitted through the switch 400 to the two protrusions. Because the two protrusions are positioned opposite each other, the force is evenly distributed to both sides of the limiting protrusion 2110, reducing wear caused by localized stress concentration and extending the service life of the switch 400 and the limiting protrusion 2110. Furthermore, the symmetrical protrusion structure allows the switch 400 to experience more stable force during sliding, preventing deviation in the movement trajectory due to unilateral weight distribution, ensuring smooth and effortless assembly and disassembly operations, and enhancing the overall structural reliability.

[0038] See Figure 1 , Figure 4 and Figure 5In one embodiment, the receiving groove 120 is provided with a first fixing tube 1210, a second fixing tube 1220, a third fixing tube 1230, and a fourth fixing tube 1240. The upper cover 200, near the battery module 300, is provided with a first positioning post 230, a second positioning post 240, a third positioning post 250, and a fourth positioning post 260. The first positioning post 230 is correspondingly disposed on the first fixing tube 1210, the second positioning post 240 is correspondingly disposed on the first fixing tube 1210, the second positioning post 240 is correspondingly disposed on the second fixing tube 1220, the third positioning post 250 is correspondingly disposed on the third fixing tube 1230, and the fourth positioning post 260 is correspondingly disposed on the fourth fixing tube 1240. It can be understood that the receiving groove 120 and the upper cover 200 form a precise positioning and connection structure through the corresponding cooperation of multiple sets of fixing tubes and positioning posts, providing a clear installation guide for the upper cover 200 to cover the housing 100. The distribution of the first to fourth fixing tubes 1240 within the receiving groove 120 corresponds one-to-one with the distribution of the first to fourth positioning posts 260 on the upper cover 200. This allows for quick alignment of the upper cover 200 with the preset position on the housing 100 during installation, avoiding installation difficulties caused by alignment deviations and significantly improving assembly efficiency. Simultaneously, the four sets of positioning structures, aligned with the upper cover 200 from different directions, form a limiting mechanism, ensuring that the connection between the upper cover 200 and the housing 100 is fixed at multiple points. This effectively prevents lateral sliding or longitudinal wobbling of the upper cover 200 during use, further enhancing the overall structural stability.

[0039] See Figure 1 and Figure 2 Furthermore, the easily detachable battery assembly structure 10 also includes a first battery fixing cover 500 and a second battery fixing cover 600. The first battery fixing cover 500 and the second battery fixing cover 600 are spaced apart on the side of the upper cover 200 near the battery module 300. The first battery fixing cover 500 is attached to one side of the battery module 300, and the second battery fixing cover 600 is attached to one side of the battery module 300. It can be understood that by providing the first battery fixing cover 500 and the second battery fixing cover 600 on the upper cover 200, and by welding the first battery fixing cover 500 and the second battery fixing cover 600 to the upper cover 200 at intervals, and by allowing the first battery fixing cover 500 and the second battery fixing cover 600 to be fitted onto the surface of the battery module 300, the battery module 300 can be stably fixed in the receiving groove 120, thus protecting the battery module 300 from collisions between the battery module 300 and the upper cover 200 during impacts and transportation.

[0040] See Figure 1 and Figure 2In one embodiment, the easily detachable battery assembly structure 10 further includes foam 700, which is disposed between the battery module 300 and the top cover 200. It can be understood that the foam 700 provides flexible cushioning protection for the battery module 300, further optimizing the fixation effect of the battery module 300 within the receiving groove 120. The foam 700 has good elasticity and deformation capacity. When the battery assembly structure is subjected to external vibration, impact, or transportation bumps, the foam 700 can absorb the impact force through its own compression and rebound, reducing the direct action of external forces on the battery module 300, lowering the risk of loosening, detachment, or damage to the internal cells of the battery module 300 due to vibration, and protecting the structural integrity and electrical performance stability of the battery module 300.

[0041] See Figure 1 and Figure 2 In one embodiment, the easily detachable battery assembly structure 10 further includes a first circuit board 800, which is disposed on the inner peripheral wall of the receiving groove and electrically connected to one end of the battery module 300. It is understood that the first circuit board 800, located on the inner peripheral wall of the receiving groove 120, provides a stable integrated carrier for the electrical connection of the battery module 300. This allows small external devices requiring charging to be charged via the first circuit board 800.

[0042] This application also includes a battery box comprising the easily detachable battery assembly structure 10 described in any of the above embodiments.

[0043] Compared with the prior art, this disclosure has at least the following advantages:

[0044] A receiving groove 120 is provided in the housing 100 so that the battery module 300 is disposed in the receiving groove 120; at the same time, the switch 400 is movably connected to the end of the housing 100, so that the switch 400 can swing relative to the housing 100; a limiting opening 210 is provided in the upper cover 200, and a limiting boss 2110 is provided on the inner wall of the limiting opening 210. The limiting boss 2110 has a first limiting groove 2111 and a second limiting groove 2112. And because the first boss corresponds to the abutment The first limiting groove 2111 is held in place, and the second protrusion 420 abuts against the second limiting groove 2112, thereby preventing the upper cover 200 from shifting relative to the housing 100. Simultaneously, the upper cover 200 has a limiting opening 210, in which the switch 400 is embedded, ensuring that the upper cover 200 does not shift left or right relative to the housing 100 under the limiting conditions of the limiting opening 210 and the switch 400. This allows the upper cover 200 to stably cover the end face of the housing 100. Because the switch 400 is movably connected to the housing 100, when the switch 400 moves away from the limiting opening 210, it causes the first protrusion 410 and the second protrusion 420 to disengage from their corresponding first limiting groove 2111 and second limiting groove 2112, causing the upper cover 200 to separate from the housing 100. The switch 400 is used to install, fix, and remove the housing 100 and the top cover 200, avoiding the need to use tools such as screwdrivers to complete the disassembly and assembly. By setting the switch 400 to be embedded in the limit port 210, it is convenient to quickly assemble and remove the top cover 200 and the housing 100 of the battery pack.

[0045] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
