Detailed Implementation

[0024] To explain in detail the technical content, structural features, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] like Figures 1 to 7 As shown, this utility model embodiment provides a battery assembly, including a battery package 1 and a battery compartment 2 for detachably installing the battery package 1. The battery package 1 includes a battery 11 and a housing 12. The battery 11 is disposed inside the housing 12. The housing 12 includes a main body. One side of the main body is provided with an elastic handle 124 protruding outward. The other side of the main body is provided with a battery connector 125 and a protrusion 126 protruding outward. The protrusion 126 is disposed on one side of the battery connector 125. The battery compartment 2 has a receiving cavity. One side of the battery compartment 2 is provided with a mating part 27 for detachably fitting and connecting with the elastic handle 124. The other side of the battery compartment 2 is provided with a clearance opening 26 corresponding to the battery connector 125 so that the battery connector 125 can extend out of the clearance opening 26. The other side of the battery compartment 2 is also provided with a snap-fit ​​arm 28 corresponding to the protrusion 126. When subjected to force, the free end of the snap-fit ​​arm 28 moves outward from the battery compartment 2 and snaps with the protrusion 126. Specifically, the battery connector 125 is electrically connected to the battery 11. The snap-fit ​​arm 28 is an elastic arm. During assembly, due to the squeezing force of the protrusion 126, the free end of the snap-fit ​​arm 28 adaptively moves outward to expand the assembly space of the battery package 1. This allows the protrusion 126 to move downward through the snap-fit ​​arm 28 and snap into the lower end face of the snap-fit ​​arm 28. This optimizes the battery insertion and removal method, which originally required restricting the insertion direction of the battery package, into a foolproof assembly method that can complete oblique insertion, flat insertion, etc. This greatly improves the user experience of end users in scenarios where the battery package 1 needs to be inserted and removed. It also avoids the problem that the battery package 1 cannot be inserted and removed correctly or the battery package 1 or the battery compartment 2 is damaged due to the user's lack of knowledge of the insertion and removal direction of the battery package 1 in the original design. During disassembly, a force is applied to the elastic handle 124 toward the inside of the battery compartment 2 to separate the elastic handle 124 from the mating part 27 to release the latch, thereby separating the battery package 1 from the battery compartment 2. Disassembly is convenient. Therefore, by placing the battery 11 inside the housing 12 and engaging the housing 12 with the battery compartment 2, a detachable connection between the battery package 1 and the battery compartment 2 is achieved. Installation is convenient and there is no problem of heat shrink film fading, resulting in a good user experience. In addition, the housing 12 and the battery compartment 2 are stably connected by engaging the mating parts 27 on both sides with the elastic handle 124 and engaging the snap-fit ​​arm 28 with the protrusion 126, resulting in a better connection effect. Moreover, the housing 12 is equipped with a battery connector 125 and an elastic handle 124, and the battery compartment 2 is correspondingly provided with an avoidance opening 26 and a mating part 27. The avoidance opening 26 and the elastic handle 124 can serve as a foolproof design, facilitating installation and disassembly.

[0026] This utility model embodiment designs a housing 12 for encapsulating the battery 11, and provides an elastic handle 124, a battery connector 125, and a protrusion 126 on the housing 12. Correspondingly, it designs a mating part 27, a clearance opening 26, and a snap-fit ​​arm 28 on the battery compartment 2. This allows the housing 12 and the battery compartment 2 to be assembled using foolproof methods such as oblique insertion and flat insertion. Installation and disassembly are very convenient, and there is no problem of heat shrink film fading, resulting in a good user experience.

[0027] In this embodiment of the present invention, the elastic buckle 124 is provided with a snap-fit ​​protrusion 1244, and the mating part 27 is provided with a snap-fit ​​interface 272 corresponding to the snap-fit ​​protrusion 1244. The snap-fit ​​protrusion 1244 is embedded in the snap-fit ​​interface 272 so that the mating part 27 snaps into the elastic buckle 124. Specifically, as shown in the figure... Figure 1 , Figure 3 , Figure 5 as well as Figure 7 As shown, the elastic handle 124 includes a first connecting segment 1241, a second connecting segment 1242, and a third connecting segment 1243 connected in sequence. The first connecting segment 1241 is connected to the main body. The second connecting segment 1242 extends upward and is spaced apart from the main body. The third connecting segment 1243 extends outward to form a handle position and protrudes from the battery compartment 2. The outer surface of the second connecting segment 1242 is provided with two evenly spaced locking protrusions 1244, corresponding to two locking interfaces 272. The spaced arrangement of the second connecting segment 1242 with the main body enables the elastic handle 124 to function as an elastic component. This facilitates disassembly by pressing the end of the third connecting segment 1243 towards the inside of the battery compartment 2, allowing the locking protrusions 1244 to separate from the locking interfaces 272. Of course, the specific structure of the elastic handle 124 can be designed according to actual needs and is not limited here. Additionally, as... Figure 5 as well as Figure 7 As shown, the upper part of the mating part 27 is also provided with a recess 271 to facilitate the extension of the third connecting section 1243, and the structure is compact.

[0028] In this embodiment of the utility model, such as Figures 1 to 7As shown, the protrusion 126 includes a first protrusion 1261, and the snap-fit ​​arm 28 includes a first snap-fit ​​arm 281 corresponding to the first protrusion 1261. The side of the main body where the battery connector 125 is located is the first side surface. The first side surface has a recessed portion 1231, and the first protrusion 1261 is provided in the recessed portion 1231. The first snap-fit ​​arm 281 includes an arm body 2811 and a mating portion 2812 connected to the free end of the arm body 2811. The mating portion 2812 extends into the battery compartment 2 to snap with the upper end face of the first protrusion 1261. Specifically, by providing the first protrusion 1261 in the recessed portion 1231 so that the mating portion 2812 extends into the battery compartment 2 to mate with the first protrusion 1261, a certain installation gap is ensured between the housing 12 and the inner wall of the battery compartment 2.

[0029] In this embodiment of the utility model, such as Figures 2 to 4 As shown, a recessed groove 1232 is provided on the upper part of the first side to form a step between the upper and lower parts of the first side. The recessed depth of the recessed part 1231 is greater than the recessed depth of the recessed groove 1232. A battery connector 125 is provided on the lower part of the first side. Specifically, the recessed groove 1232 makes it easier for the battery package 1 to be inserted into the battery compartment 2, reducing interference between the upper part of the first side and the battery compartment 2. The design is very ingenious.

[0030] In this embodiment of the utility model, such as Figures 2 to 7 As shown, the protrusion 126 further includes a second protrusion 1262, and the snap-fit ​​arm 28 further includes a second snap-fit ​​arm 282 corresponding to the second protrusion 1262. The recess 1231 is located at one end of the first side surface, and the second protrusion 1262 is located at the lower part of the first side surface. The second protrusion 1262 and the first protrusion 1261 are respectively located on both sides of the battery connector 125. The lower end face of the second snap-fit ​​arm 282 is snapped with the upper end face of the second protrusion 1262. Specifically, a notch 241 is also provided directly below the second snap-fit ​​arm 282. The second protrusion 1262 is embedded in the notch 241 to snap with the second snap-fit ​​arm 282. In this embodiment of the present invention, the arrangement of the first protrusion 1261 and the second protrusion 1262 ensures a stable connection between the battery compartment 2 and the housing 12.

[0031] In this embodiment of the utility model, such as Figures 1 to 4As shown, the main body includes a shell bottom 121 and a first sidewall 122 and a second sidewall 123 disposed on both sides of the shell bottom 121. The first sidewall 122 is provided with an elastic handle 124, and the second sidewall 123 is provided with a battery connector 125 and a protrusion 126. Specifically, the main body, the elastic handle 124, and the protrusion 126 are all made of plastic. The main body, the elastic handle 124, and the protrusion 126 can be integrally molded. The battery 11 is fixed between the first sidewall 122 and the second sidewall 123 and can be further bonded to the main body using adhesives to form a whole. Furthermore, this embodiment of the invention only provides the first sidewall 122 and the second sidewall 123, effectively improving heat dissipation performance.

[0032] In this embodiment of the utility model, such as Figures 5 to 7 As shown, the battery compartment 2 includes a compartment bottom 21, which includes a first side, a second side, a third side, and a fourth side arranged sequentially. The first side, the second side, and the third side are respectively provided with a first compartment wall 22, a second compartment wall 23, and a third compartment wall 24. The first compartment wall 22, the second compartment wall 23, and the third compartment wall 24 are connected in sequence. The fourth side is provided with a limiting protrusion 25, which is located in the middle of the fourth side. The first compartment wall 22, the second compartment wall 23, the third compartment wall 24, and the limiting protrusion 25 form a receiving cavity. A mating part 27 is provided on the first compartment wall 22, and a snap-fit ​​arm 28 is provided on the third compartment wall 24. Specifically, the mating part 27 can be a component of the first compartment wall 22. The snap-fit ​​spring arm 28 is connected to the third compartment wall 24 at only one end to ensure that the free end of the snap-fit ​​spring arm 28 can move outward when subjected to force. The spring arm body 2811 of the first snap-fit ​​spring arm 281 and the second snap-fit ​​spring arm 282 both extend along the height direction of the third compartment wall 24. The projection of the spring arm body 2811 of the first snap-fit ​​spring arm 281 and the second snap-fit ​​spring arm 282 in the height direction of the third compartment wall 24 is located inside the projection of the third compartment wall 24 along its height direction. The structure is compact and simple. In addition, the battery compartment 2 can also be made of plastic. The battery compartment 2 can be directly integrally molded. Moreover, a limiting protrusion 25 is set on the fourth side instead of the side wall. While ensuring the stable installation of the battery package 1, the heat dissipation performance of the battery compartment 2 is improved.

[0033] In this embodiment of the utility model, such as Figure 2 as well as Figure 4As shown, battery connector 125 is a blade-type battery connector. Specifically, the use of a blade-type battery connector replaces the original WTB connector, which provides a foolproof design when inserting the battery package 1, improving the user experience. In the design of the blade-type battery connector, the contact area between the male and female connectors is maximized, while corresponding interference is designed to improve connection stability. A surface contact method is used, and when the battery package 1 is inserted into the battery compartment 2, the feel becomes noticeably tighter, helping to remind the user whether the battery package 1 is properly engaged, further improving the user experience.

[0034] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
