Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] In some related technologies, after the battery pack is installed into the mounting cavity of the casing, one to two screws are installed on each side of the battery pack. Generally, about four to seven screws are needed to secure the battery to the casing. During the installation process, screws can easily fall into the mounting cavity. If a fallen screw is not detected in time, it can compress or even damage surrounding components after the back cover is closed. Moreover, the screwdriver can easily scratch the battery cells during movement. Furthermore, assembling the battery pack by tightening multiple screws is inefficient.

[0026] To address the aforementioned issues, this utility model provides a battery assembly that eliminates the need for screws to secure the battery assembly to the housing during installation. This prevents screws from falling into the mounting cavity and avoids the risk of screwdrivers scratching the battery cells. It also improves the assembly efficiency of the battery assembly.

[0027] The following describes in detail, with reference to the accompanying drawings, the specific structure of a battery assembly provided by this utility model and its corresponding technical effects.

[0028] It should be noted that the battery component is used in the terminal device. In this embodiment, the terminal device can be understood as a laptop computer.

[0029] Please refer to Figures 1-6 The terminal device provided in this embodiment of the utility model includes a housing 1000 and a battery assembly 200.

[0030] In detail, the housing 1000 includes a housing body 100 and a rear cover 300. The housing body 100 has a receiving compartment 101, in which a first snap-fit ​​member 110 is provided, and the battery assembly 200 is disposed in the receiving compartment 101.

[0031] The battery assembly 200 includes connected battery cells 240 and a support 2000, with the battery cells 240 disposed within the support 2000. A resilient buckle 210 is provided on the outer side of the support 2000.

[0032] In detail, the bracket 2000 includes a frame 2100 and a spring clip 210. The frame 2100 is assembled with the battery unit 240. The spring clip 210 is set on the frame and can deform under external force to engage or disengage with the first snap-fit ​​member 110 on the housing body 100. The battery bracket 2000 does not need to be connected to the housing body 100 by screws. This can fundamentally avoid the situation where screws fall into the housing 1000 due to the installation of the battery bracket 2100, and also avoid the risk of screwdrivers scratching the battery cells.

[0033] The elastic buckle 210 of the battery assembly 200 engages with the first snap-fit ​​member 110, and the rear cover 300 covers the housing body 100, thereby covering the housing compartment 101 of the housing body 100, thus preventing the battery assembly 200 and some electronic components inside the housing body 100 from being exposed.

[0034] The rear cover 300 is provided with a second latching member 310, which is used to cooperate with the elastic buckle 210 to lock the elastic buckle 210 with the first latching member 110. Specifically, in this embodiment, the second latching member 310 and the elastic buckle 210 are latched together.

[0035] In this embodiment, the locking of the elastic buckle 210 and the first snap-fit ​​member 110 can be understood as follows: after the elastic buckle 210 and the first snap-fit ​​member 110 are engaged, the second snap-fit ​​member 310 restricts the deformation range of the elastic buckle 210. Due to the restriction of the second snap-fit ​​member 310, the elastic buckle 210 cannot easily come off the first snap-fit ​​member 110.

[0036] After the second snap fastener 310 is disengaged from the elastic buckle 210, the elastic buckle 210 can be separated from the first snap fastener 110.

[0037] It should be noted that in this embodiment, the disengagement of the second snap-fit ​​310 from the elastic buckle 210 can be understood as the second snap-fit ​​310 completely disengaging from the elastic buckle 210. In other words, in this embodiment, after the battery assembly 200 is installed into the receiving compartment 101 and the elastic buckle 210 of the battery assembly 200 is snapped into the first snap-fit ​​110, and then the rear cover 300 is connected to the housing body 100 to cover the receiving compartment 101, the second snap-fit ​​310 and the elastic buckle 210 are locked together. At this time, the elastic buckle 210 and the first snap-fit ​​110 are restricted by the second snap-fit ​​310 and cannot be easily separated, thereby fixing the battery assembly 200 inside the housing body 100, and also fixing the battery assembly 200 to the rear cover 300.

[0038] In detail, when it is necessary to disconnect the shell body 100 from the battery assembly 200, the second snap fastener 310 can be completely disengaged from the elastic buckle 210. At this time, the second snap fastener 310 will no longer restrict the separation of the first snap fastener 110 and the elastic buckle 210. The elastic buckle 210 can then be moved away from the first snap fastener 110 to separate the elastic buckle 210 from the first snap fastener 110.

[0039] In this embodiment, it is not necessary to fix the battery assembly 200 in the housing 101 with screws, which can fundamentally avoid the occurrence of screws falling into the housing 101 and also avoid the risk of screwdrivers scratching the battery cells.

[0040] Please refer to Figures 3-6 Furthermore, after the second snap fastener 310 on the rear cover 300 engages with the elastic buckle 210, the rear cover 300 covers the receiving compartment 101, and the elastic buckle 210 of the battery assembly 200 is locked to the first snap fastener 110 in the receiving compartment 101, which can effectively improve the assembly efficiency of the battery assembly 200.

[0041] Please refer to Figure 4 Specifically, in this embodiment, the elastic buckle 210 includes a main body 2101, which is connected to the outer side of the bracket 2000. More specifically, the main body 2101 is connected to the outer side of the frame 2100. The main body 2101 forms a mating space 216, into which the second snap-fit ​​member 310 of the rear cover 300 extends. It can be understood that after the second snap-fit ​​member 310 of the rear cover 300 extends into the mating space 216, the deformation range of the elastic buckle 210 can be limited, and the elastic buckle 210 cannot easily disengage from the first snap-fit ​​member 110.

[0042] The elastic buckle 210 also includes a snap fastener 2102 connected to the main body 2101. Understandably, the snap fastener 2102 can engage or disengage with the first snap fastener 110 under the action of external force.

[0043] The fastener 2102 engages with the first fastener 110 of the shell body 100, and the second fastener 310 is inserted into the mating space 216, which can limit the deformation range of the fastener 2102 to prevent the fastener 2102 from disengaging from the first fastener 110.

[0044] In detail, in this embodiment, the mating space 216 is a mating hole for insertion into the second snap-fit ​​member 310. The snap-fit ​​member 2102 has a mating part 215 on the side away from the mating space 216. The mating part 215 is used to snap-fit ​​with the shell body 100. That is, the snap-fit ​​member 2102 is used to snap-fit ​​with the first snap-fit ​​member 110 through the mating part 215. In detail, the snap fastener 2102 includes a first connecting part 213, and a mating part 215 for snapping and engaging with the first snap fastener 110 is provided on the side of the first connecting part 213 away from the mating space.

[0045] The mating space 216 can be snapped into the second snap-fit ​​member 310, or the mating space 216 can be clearance-fitted with the second snap-fit ​​member 310.

[0046] The first snap-fit ​​member 110 is provided with a snap-fit ​​part. After the second snap-fit ​​member 310 is inserted into the mating hole, the second snap-fit ​​member 310 locks the mating part 215 with the snap-fit ​​part.

[0047] Understandably, after the battery assembly 200 is installed in the receiving compartment 101 and the mating part 215 is engaged with the snap-fit ​​part, after the second snap-fit ​​member 310 is inserted into the mating space 216, since the second snap-fit ​​member 310 is inserted into the mating space 216, the second snap-fit ​​member 310 can restrict the mating part 215 from moving away from the snap-fit ​​part, thus preventing the mating part 215 from easily separating from the snap-fit ​​part, thereby locking the mating part 215 with the snap-fit ​​part.

[0048] It should be noted that the buckle 2102 in this embodiment can deform relative to the main body 2101 so that the buckle 2102 can engage with or disengage from the shell body 100. That is, during the process of the buckle 2102 deforming relative to the main body 2101, the buckle 2102 can engage with or disengage from the first engaging member 110.

[0049] In detail, a deformation space 219 is formed between the fastener 2102 and the main body 2101. The deformation space 219 is used to allow the fastener 2102 to deform relative to the main body 2101, thereby generating displacement and enabling the fastener 2102 to engage with or disengage from the first engaging member 110. It should be noted that the displacement generated by the deformation of the fastener 2102 relative to the main body 2101 can be understood as the displacement of the part of the fastener 2102 not connected to the main body 2101, thereby changing the distance between the mating part 215 on the fastener 2102 and the engaging part on the first engaging member 110, so as to achieve the engagement or disengagement of the fastener 2102 with or from the first engaging member 110.

[0050] In detail, in this embodiment, the deformation space 219 is connected to the mating space 216, that is, the deformation space 219 in this embodiment is a notch connected to the mating space 216. Of course, in some other optional embodiments, the deformation space 219 can also be a solid deformable structure disposed between the fastener 2102 and the main body 2101.

[0051] Therefore, after the second snap fastener 310 removes the mating space 216, the second snap fastener 310 no longer restricts the mating part 215 from the snap fastener part. The elastic buckle 210 can at least partially recover, and the user can also deform the elastic buckle 210 to move the mating part 215 away from the snap fastener part until the mating part 215 is separated from the snap fastener part.

[0052] In some embodiments, the second latching member 310 can extend into both the mating space 216 and the deformation space 219 simultaneously. It is understood that when the second latching member 310 is located in the deformation space 219, it can better limit the deformation of the latching member 2102, so as to lock the latching member 2102 with the first latching member 110.

[0053] Of course, in some other embodiments, the second snap-fit ​​member 310 only extends into the mating space 216 to limit the deformation of the snap-fit ​​member 2102.

[0054] Optionally, one of the mating part 215 and the snap-fit ​​part is a snap-fit ​​hole 111, and the other is a snap-fit ​​protrusion, with the snap-fit ​​hole 111 and the snap-fit ​​protrusion engaging.

[0055] In this embodiment, the mating part 215 is a snap-fit ​​protrusion, and the snap-fit ​​part of the first snap-fit ​​member 110 is a snap-fit ​​hole 111. The snap-fit ​​protrusion on the elastic buckle 210 can be snapped into the snap-fit ​​hole 111 to realize the installation of the battery assembly 200 in the receiving compartment 101. After the second snap-fit ​​member 310 is inserted into the mating space 216, the second snap-fit ​​member 310 can restrict the snap-fit ​​protrusion from moving away from the snap-fit ​​hole 111, thereby realizing the locking of the elastic buckle 210 and the first snap-fit ​​member 110.

[0056] Of course, in some other alternative embodiments, the mating part 215 may also be a snap hole, and the snap-fit ​​part may be a snap-fit ​​protrusion.

[0057] In detail, the fastener 2102 also includes a second connecting part 214. One end of the first connecting part 213 is connected to the main body 2101, and the other end of the first connecting part 213 is provided with the second connecting part 214, which extends away from the main body 2101.

[0058] Understandably, the second connecting part 214 makes it easier for the user to move the first connecting part 213, thereby improving the efficiency of disengaging the buckle 2102 from the first snap-fit ​​part 110. In other words, it can improve the efficiency of disengaging the snap-fit ​​protrusion from the snap-fit ​​hole 111.

[0059] In other words, when it is necessary to remove the battery assembly 200 from the housing 101, after the second snap-fit ​​310 is removed from the mating space 216, the user can move the second connecting part 214 to deform the first connecting part 213 away from the first snap-fit ​​110, so that the snap-fit ​​protrusion is completely disengaged from the snap hole 111 on the first snap-fit ​​110.

[0060] Furthermore, since the second connecting part 214 is located at the end of the first connecting part 213 away from the main body 2101, it makes it easier for the user to move the second connecting part 214 and to make the first connecting part 213 deform away from the first snap-fit ​​member 110, thereby causing the mating part 215 to disengage from the snap-fit ​​hole 111.

[0061] In detail, the main body 2101 includes a base plate 211 and a mounting part 212. The mounting part 212 and the first connecting part 213 are spaced apart on the base plate 211. The space between the mounting part 212 and the first connecting part 213 can be understood as the deformation space 219 in this embodiment. The base plate 211, the mounting part 212 and the first connecting part 213 together define a mating space 216. The mating part 215 is located on the side of the first connecting part 213 away from the mounting part 212. The first snap-fit ​​member 110 is located on the side of the first connecting part 213 away from the mounting part 212.

[0062] After the battery assembly 200 is engaged with the locking protrusion on the first connecting part 213 into the locking hole 111 on the first locking member 110, and then the second locking member 310 is engaged into the locking hole 111, since the second locking member 310 is located in the mating space 216 and between the mounting part 212 and the first connecting part 213, it can restrict the first connecting part 213 from moving towards the mounting part 212, thereby restricting the locking protrusion from coming out of the locking hole 111. The second locking member 310 can play the role of restricting the locking protrusion from coming out of the locking hole 111, ensuring that the battery assembly 200 is stably installed in the receiving compartment 101.

[0063] Optionally, the elastic buckle 210 is made of a deformable material, which further facilitates the deformation of the buckle 2102. Understandably, after the second snap-fit ​​310 is removed from the mating space 216, the user can move the first connecting part 213 away from the first snap-fit ​​110 so that the snap-fit ​​protrusion disengages from the snap hole 111, so as to facilitate the removal of the battery assembly 200 from the receiving compartment 101.

[0064] Optionally, at least one of the side of the main body 2101 near the fastener and the side of the fastener near the main body 2101 is provided with a first abutting portion 217, which is used to restrict the rear cover 300 from disengaging from the mating space 216. Specifically, in this embodiment, the side of the main body 2101 near the fastener is provided with a first abutting portion 217, which is used to restrict the second mating member from easily disengaging from the mating space 216.

[0065] Please continue to refer to this. Figure 5 In this embodiment, the mounting part 212 has a first abutting part 217 protruding on the side near the first connecting part 213, and the outer periphery of the second snap-fit ​​member 310 has a second abutting part 3111 protruding. The second abutting part 3111 is used to abut against the first abutting part 217 to restrict the second snap-fit ​​member 310 from disengaging from the mating space 216. After the second snap-fit ​​member 310 and the mating space 216 are engaged, the first abutting part 217 is located on the side of the second abutting part 3111 away from the bottom wall of the receiving compartment 101. The first abutting part 217 is used to abut against the second abutting part 3111 to restrict the snap-fit ​​member from disengaging from the mating space 216.

[0066] Understandably, the arrangement of the first abutment portion 217 and the second abutment portion 3111 prevents the second latching member 310 on the back cover 300 from easily dislodging from the mating space 216. Understandably, when the elastic buckle 210 is made of a deformable material, the elastic buckle 210 will deform when the second latching member 310 is pulled out, thereby causing the second latching member 310 to dislodge from the mating space 216.

[0067] In detail, in this embodiment, the second abutment portion 3111 is disposed at the end of the second latching member 310 away from the rear cover 300. To facilitate the removal of the second latching member 310 from the mating space 216, the end of the second latching member 310 away from the rear cover 300 is provided with a plurality of spaced-apart second abutment portions 3111, which can retract radially under external force. Specifically, in this embodiment, the second latching member 310 includes two spaced-apart latching posts 311, each of which is provided with a second abutment portion 3111. Since the latching posts 311 are spaced-apart, when the second latching member 310 is removed from the mating space 216, the end of the latching post 311 away from the rear cover 300 will retract radially, so as to facilitate the removal of the second latching member 310 from the mating space 216.

[0068] In the direction near the rear cover 300, the radial dimension of the second abutment portion 3111 gradually increases, and the end face of the second abutment portion 3111 opposite to the rear cover 300 is used to abut against the first abutment portion 217. It can be understood that, since the radial dimension of the second abutment portion 3111 gradually increases in the direction near the rear cover 300, the outer peripheral surface of the second abutment portion 3111 has a certain guiding effect, so as to facilitate the insertion of the snap-fit ​​portion into the mating space 216.

[0069] Optionally, in some embodiments, the size of the second snap-fit ​​member 310 is larger than the size of the mating hole. Therefore, during the insertion of the second snap-fit ​​member 310 into the mating hole, the first connecting portion 213 gradually moves away from the mounting portion 212. At this time, the mating hole gradually opens, allowing the snap-fit ​​protrusion to be inserted deeper into the snap hole 111. Therefore, when the second snap-fit ​​member 310 on the rear cover 300 is inserted into the mating hole, the snap-fit ​​protrusion on the elastic buckle 210 can more stably engage with the snap hole 111 on the first snap-fit ​​member 110, allowing the battery assembly 200 to be fixedly installed in the receiving compartment 101.

[0070] Optionally, the battery assembly 200 also includes an electrical connector 230, which protrudes from one side edge of the battery cell 240. A resilient buckle 210 is disposed on one side edge of the battery holder, with the resilient buckle 210 spaced apart from the side wall of the electrical connector 230. The protruding electrical connector 230 ensures a more secure and stable electrical contact for the battery assembly 200. Furthermore, since the resilient buckle 210 is located on one side of the electrical connector 230, the risk of the battery assembly 200 becoming loose or falling off due to accidental contact with the resilient buckle 210 during daily use can be avoided.

[0071] Please refer to Figure 2 and Figure 7In detail, the battery bracket 2000 in this embodiment is also provided with a connector 218, the connector 218 has a threaded hole 400, the back cover 300 is provided with a mounting hole 312 corresponding to the threaded hole 400, and the terminal device also includes a threaded fastener, which can pass through the mounting hole 312 and be threadedly connected to the threaded hole 400.

[0072] Understandably, by sequentially threading fasteners through mounting holes 312 and threaded into threaded holes 400, the connection strength between the rear cover 300 and the battery assembly 200 can be ensured. The threaded fasteners can be screws.

[0073] Optionally, in some embodiments, the bottom wall of the receiving compartment 101 of the housing body 100 may also be provided with a connection hole corresponding to the threaded hole 400. The connection hole can be a threaded hole 400, that is, the threaded fastener can pass through the mounting hole 312 in sequence and be threadedly connected to the threaded hole 400 on the connector 218 and the threaded hole 400 on the housing body 100. This not only ensures the stable connection of the battery assembly 200 installed on the receiving compartment 101, but also ensures the stability of the connection between the rear cover 300 and the housing body 100.

[0074] Please refer to Figures 6-7 Optionally, in order to improve the assembly efficiency of the battery assembly 200, the connector 218 is also provided with a positioning hole 2181, and the receiving compartment 101 is also provided with a positioning post 140 corresponding to the positioning hole 2181, with the positioning post 140 passing through the positioning hole 2181.

[0075] Understandably, the positioning post 140 and positioning hole 2181 make it easy for installers to quickly and accurately install the battery assembly 200 into the receiving compartment 101.

[0076] Please refer to Figure 3 , Figures 7-8 In detail, in this embodiment, there are two connectors 218, which are spaced apart from the elastic buckle 210 along the first direction, with the elastic buckle 210 located between the two connectors 218. It can be understood that the number of mounting holes 312 on the back cover 300 corresponds one-to-one with the number of threaded holes 400 in the battery assembly 200 to ensure the connection stability between the back cover 300 and the battery assembly 200.

[0077] Please continue to refer to this. Figure 3 and Figure 7 In detail, in this embodiment, the battery bracket 2000 is also provided with a connecting structure 220, which is used to snap onto the shell body 100 of the housing 1000. The connecting structure 220 and the elastic buckle 210 are respectively provided on opposite sides of the battery bracket 2100, thereby stably fixing the battery bracket 2100 in the receiving compartment 101.

[0078] In detail, the connecting structure 220 and the elastic buckle 210 are spaced apart along the second direction, and the receiving compartment 101 is also provided with a third snap-fit ​​member 130 that snaps into the connecting structure 220.

[0079] In this embodiment, the first connecting portion 213 and the mounting portion 212 are spaced apart on the base plate 211 along the second direction, and the first connecting portion 213 is located on the side of the mounting portion 212 away from the connecting structure 220. When installing the battery assembly 200, the connecting structure 220 can be pre-engaged with the third snap-fit ​​member 130, and then the elastic buckle 210 can be engaged with the first snap-fit ​​member 110. Through the first snap-fit ​​member 110 and the third snap-fit ​​member 130 in the receiving compartment 101, the movement of the battery assembly 200 in the first direction, the second direction, and the depth direction of the receiving compartment 101 can be restricted, so that the battery assembly 200 is stably installed in the receiving compartment 101.

[0080] After the second snap-fit ​​310 on the cover is inserted into the mating space 216 of the elastic buckle 210, the snap hole 111 on the first snap-fit ​​110 can be locked with the mating part 215 on the first connecting part 213, thus ensuring the stability of the battery assembly 200 in the receiving compartment 101.

[0081] It should be noted that, in this embodiment, the installation direction of the snap-fit ​​part and the mating space 216 is parallel to the depth direction of the receiving chamber 101. Therefore, when the rear cover 300 is placed on the receiving chamber 101 along the depth direction of the receiving chamber 101, the installation of the snap-fit ​​part and the mating space 216 can be completed, improving the assembly efficiency of the rear cover 300.

[0082] It is understood that in this embodiment, the first direction can be understood as the length direction of the battery assembly 200, and the second direction can be understood as the width direction of the battery assembly 200.

[0083] In detail, the third snap-fit ​​member 130 in this embodiment has a snap-fit ​​hole 131 facing the elastic buckle 210. The connection structure 220 in this embodiment is a mating plate for extending into the snap-fit ​​hole 131. After the mating plate is inserted into the snap-fit ​​hole 131, the snap-fit ​​hole 131 can restrict the movement of the battery assembly 200 in the depth direction of the receiving compartment 101 along the direction close to the rear cover 300. The snap-fit ​​hole 131 can also restrict the movement in the second direction along the direction away from the elastic buckle 210.

[0084] The number of third connectors 130 and the number of connecting structures 220 are both multiple and are set in a one-to-one correspondence. The multiple third connectors 130 are spaced apart along the first direction, thereby further enhancing the stability of the battery assembly 200 installed in the housing 101.

[0085] Of course, the number of first card connectors 110, second card connectors 310 and elastic buckles 210 can also be multiple and set in a one-to-one correspondence, with multiple first card connectors 110 spaced apart along the first direction.

[0086] In detail, the "multiple" in this embodiment can be understood as two or more quantities. For example, the number of the first snap-fit ​​connector 110, the second snap-fit ​​connector 310, and the elastic buckle 210 can be two. The number of the third snap-fit ​​connector 130 and the connecting structure 220 can be four.

[0087] In detail, in order to ensure the connection strength of the two first snap-fit ​​pieces 110, the shell body 100 is also provided with reinforcing ribs 150, and the two first snap-fit ​​pieces 110 are spaced apart on the reinforcing ribs 150 along the first direction.

[0088] In detail, during the installation process of the battery assembly 200 provided in this embodiment, multiple mating plates on the battery assembly 200 can be pre-inserted into multiple snap-fit ​​holes 131 one by one. Then, the snap-fit ​​protrusion of the elastic buckle 210 on the battery assembly 200 is snapped into the snap-fit ​​hole 111 of the first snap-fit ​​member 110. At this time, the positioning post 140 in the receiving compartment 101 is also inserted into the positioning hole 2181 on the connector 218. Then, the rear cover 300 is placed on the shell body 100 so that the rear cover 300 covers the receiving compartment 101. During the process of the rear cover 300 being placed on the shell body 100, the second snap-fit ​​member 310 extends into the mating space 216 until the second abutment part 3111 is located on the side of the first abutment part 217 near the bottom wall of the receiving compartment 101, so that the snap-fit ​​protrusion and the buckle are locked. It is best to screw the threaded fastener through the mounting hole 312 and into the threaded hole 400 to complete the assembly.

[0089] In the terminal device provided in this embodiment, during the disassembly process of the battery assembly 200, the threaded fasteners can be removed first, and then the back cover 300 can be pulled out. After the second snap fastener 310 is removed from the mating space 216, the user can move the second connecting part 214 to deform the first connecting part 213, causing the mating part 215 to move away from the snap hole 111 until it is dislodged from the snap hole 111. Then, the side of the battery assembly 200 with the elastic buckle 210 is lifted, and the mating plate is pulled out of the snap hole 131, thereby completing the battery disassembly.

[0090] Understandably, in this embodiment, the installation and disassembly of the battery assembly 200 can reduce the number of screws in the receiving compartment 101, thereby preventing screws from falling into the receiving compartment 101 and avoiding the risk of screwdrivers scratching the battery cells.

[0091] In summary, this utility model embodiment provides a terminal device, which includes a battery assembly 200, a housing body 100, and a back cover 300. The battery assembly 200 includes a battery bracket 2000 and battery cells 240. The battery bracket 2000 includes a frame 2100 and an elastic buckle 210. The housing body 100 has a receiving compartment 101, in which a first snap-fit ​​member 110 is provided. The battery assembly 200 is housed in the receiving compartment 101. The elastic buckle 210 can deform under the action of external force to engage or disengage with the first snap-fit ​​member 110. The back cover 300 is connected to the housing body 100 to cover the receiving compartment 101. The back cover 300 is provided with a second snap-fit ​​member 310, which engages with the elastic buckle 210 to lock the elastic buckle 210 to the first snap-fit ​​member 110. There is no need to fix the battery assembly 200 in the housing 101 with screws, which can prevent screws from falling into the housing 101 and also avoid the risk of screwdrivers scratching the battery cells.
