[0011] Preferably, a limiting block is fixed on one side of the connecting block, and a limiting hole extending along the first direction is provided on the housing. The limiting block extends into the limiting hole and can slide along the first direction. When the connecting block is in the first position, the side of the limiting block away from the bottom of the cavity in the first direction abuts against the wall of the limiting hole.

[0013] Preferably, the housing is provided with a fixing rod, the fixing rod and the cavity bottom have an installation gap in the first direction, the fulcrum is located on the side of the fixing rod facing the cavity bottom, and the hook can be connected to the fulcrum through the installation gap.

[0014] Preferably, a sleeve is provided on the battery, located on the outer periphery of the card block, and the sleeve is fitted onto the outer side of one end of the housing in the first direction.

[0015] An electronic device includes a housing and the battery connection module described above; the housing has a battery compartment with an opening in a first direction and a bottom at the other end, the bottom of the compartment being fixedly connected to the housing, and in the first direction, the bottom of the inner cavity and the connecting block are arranged sequentially along the direction close to the opening; the battery in the battery compartment has only the first direction of freedom of movement, the battery can enter the battery compartment through the opening, and the locking block on the battery is connected to the locking structure.

[0016] The battery connection module provided by this utility model includes a housing, a connecting block, a hook, and a battery. The connecting block is slidably connected to the inner cavity of the housing along a first direction. The outer end face of the connecting block in the first direction is provided with a snap-fit ​​structure. One end of the battery in the first direction is provided with a snap-fit ​​block for engaging with the snap-fit ​​structure. The hook is located in the inner cavity, with one end away from the bottom of the cavity being a locking end. The other end is connected to a fulcrum in the inner cavity, and there is a hook elastic structure between the hook and the fulcrum, so that the hook can be reset to the zero position around the fulcrum under the elastic reset force of the hook elastic structure. A locking block is fixed on the first side of the connecting block. The locking block is provided with a first guide surface inclined relative to the first direction, and a locking surface is provided on the end face away from the bottom of the cavity.

[0017] As the connecting block moves from the first position into the inner cavity, the first guide surface can push the locking end and cause the hook to swing around the fulcrum. When the connecting block moves to the second position, the hook can swing back to the zero position under the action of the elastic restoring force of the hook elastic structure, and block the locking surface at the end away from the bottom of the cavity.

[0018] When installing the battery, the battery moves close to the connecting block along the first direction, causing its locking block to engage with the locking structure. As the battery and the connecting block are pushed along the first direction toward the bottom of the cavity, the connecting block moves from the first position to the second position. At this time, the locking end of the hook is pushed by the first guide surface of the locking block, and the locking block can overcome the elastic force of the hook's elastic structure, causing the hook to swing. When the connecting block moves into place, the locking end of the hook resets and swings, blocking the locking surface of the locking block and preventing the connecting block from moving outward from the second position, thereby preventing the battery from falling out of the battery compartment.

[0019] This battery connection module utilizes the snap-fit ​​mechanism between the battery's locking block and the locking structure, along with the locking mechanism between the locking block and the hook, to achieve battery installation and fixation in the first direction. Primarily achieved through a pushing motion, it reduces the need for tools, simplifies operation, and improves installation efficiency. During assembly, after the hook is installed on the housing, it automatically remains at the zero-point position relative to the fulcrum under elastic force. Subsequent assembly of the connecting block into the inner cavity eliminates the need for manual adjustment of the hook's position, further enhancing assembly efficiency. Attached Figure Description

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] The core of this utility model is to provide a battery connection module and electronic device with high battery installation efficiency.

[0054] It should be noted that, for clarity, in the description of the embodiments of this application, when referring to directions such as up, down, left, and right, unless otherwise specified, the corresponding terms are... Figures 14 to 19 The illustrated directions are for illustrative purposes only and should not be construed as limiting the scope of this application. Figures 14 to 19 In the diagram, the first direction X corresponds to the up and down direction, with the upper direction corresponding to the direction of the opening 33 near the inner cavity 3 and the lower direction corresponding to the direction of the bottom 34 of the inner cavity 3; the second direction Y corresponds to the left and right direction, with the left side corresponding to the second side in the second direction Y and the right side corresponding to the first side in the second direction Y.

[0055] For a specific embodiment of the battery connection module provided by this utility model, please refer to Embodiment 1. Figures 1 to 20It includes the housing 2, the connecting block 5, the hook 9 and the battery 8.

[0056] like Figure 15 As shown, the connecting block 5 is slidably connected to the inner cavity 3 of the housing 2 along the first direction X. The connecting block 5 has a snap-fit ​​structure 6 on its outer end face 58 in the first direction X. The battery 8 has a snap-fit ​​block 81 at one end in the first direction X, which engages with the snap-fit ​​structure 6, thereby allowing the connecting block 5 to be detachably connected to the battery 8. It should be noted that, in the first direction X, the end face of the connecting block 5 located on the opening side of the inner cavity 3 is the outer end face 58, and the end face at the other end is the inner end face 59.

[0057] like Figure 15 As shown, the hook 9 is located in the inner cavity 3, and the end furthest from the bottom 34 of the inner cavity 3 is the locking end 91 (corresponding to...). Figure 15 (the top of the middle), the other end (corresponding to) Figure 15 The bottom end of the hook 9 is connected to the fulcrum 41 in the inner cavity 3 via a hook elastic structure, so that the hook 9 can elastically return to the zero position around the fulcrum 41 under the action of the hook elastic structure. That is to say, when the hook elastic structure does not elastically deform, the hook 9 is at the zero position relative to the fulcrum 41. (Refer to...) Figure 17 The position of hook 9 in the middle.

[0058] like Figure 18 As shown, a locking block 52 is fixed on the first side 55 of the connecting block 5. The locking block 52 is provided with a first guide surface 521 that is inclined relative to the first direction X, and a locking surface 523 is provided on the end face away from the bottom of the cavity 34, which is used to cooperate with the locking end 91 of the hook 9 to lock the connecting block 5 in the second position.

[0059] It should be noted that when the connecting block 5 moves to the first position, the second position, and the third position, these all refer to its position relative to the housing 2.

[0060] After the connecting block 5 is subjected to pressure in the first direction X, refer to Figure 17 , Figure 18 , Figure 19 , Figure 14 The order is such that connecting block 5 is from the first position ( Figure 17 During the movement of the connecting block 5 into the inner cavity 3, the first guide surface 521 can push the locking end 91 and drive the hook 9 to gradually swing around the fulcrum 41. When the connecting block 5 moves to the second position ( Figure 14 When the hook 9 is in use, it can swing back to the zero position under the action of the elastic restoring force of the hook elastic structure, and block the locking surface 523 at the end away from the bottom of the cavity 34.

[0061] In this embodiment, during installation, the battery 8 moves along the first direction X towards the connecting block 5, causing the battery 8's locking block 81 to engage with the locking structure 6. When the battery 8 and the connecting block 5 are pushed along the first direction X towards the bottom 34 of the inner cavity 3, the connecting block 5 moves from the first position to the second position. At this time, the locking end 91 of the hook 9 is pushed by the first guide surface 521 of the locking block 52, and the locking block 52 can overcome the elastic force of the hook's elastic structure, causing the hook 9 to swing. When the connecting block 5 moves to the correct position, the locking end 91 of the hook 9 resets and swings (either swinging back or not swinging back to the zero position), blocking the locking surface 523 of the locking block 52, preventing the connecting block 5 from moving outward from the second position, thereby preventing the battery 8 from falling out of the battery compartment 7.

[0062] By using this battery connection module, the battery 8 can be installed and fixed in the first direction X through the snap-fit ​​between the battery 8 and the snap-fit ​​structure 6, and the locking block 52 and the hook 9. This is mainly achieved through a pushing action, reducing the need for tools, making operation convenient, and improving installation efficiency. During assembly, after the hook 9 is installed on the housing 2, it automatically stops at the zero point relative to the fulcrum 41 under the action of elasticity. During the subsequent assembly of the connecting block 5 into the inner cavity 3, there is no need to manually adjust the position of the hook 9, further improving assembly efficiency.

[0063] Furthermore, to improve the reliability of battery installation and the efficiency of disassembly, such as Figure 9 and Figure 10 As shown, the battery connection module also includes an elastic element 1 disposed in the housing 2, which can be a compression spring, or in other embodiments, a spring sheet. The elastic element 1 provides an outward elastic force to the connecting block 5, specifically referring to outward movement relative to the inner cavity 3 along the first direction X.

[0064] At this time, as Figure 14 As shown, when the connecting block 5 is in the second position, the snap-fit ​​structure 6 snaps into the snap-fit ​​block 81 of the battery 8. The locking end 91 at the top of the hook 9 blocks the locking surface 523 at the top of the locking block 52, limiting the upward movement of the connecting block 5. The elastic member 1 is pressed upward elastically, which can limit the downward movement of the connecting block 5, thereby improving the stability of the connecting block 5 in the second position and preventing the connecting block 5 from shaking up and down in the inner cavity 3.

[0065] In some embodiments, to improve structural compactness, such as Figure 10 As shown, the inner end face 59 of the connecting block 5 (corresponding to) Figure 17 A receiving groove 56 is provided on the bottom surface of the connecting block 5, and in the first direction X, the elastic member 1 abuts between the groove wall of the receiving groove 56 and the bottom 34 of the inner cavity 3. By providing the receiving groove 56, the utilization rate of the internal space of the connecting block 5 can be improved, and the space required for the inner cavity 3 in the first direction X can be reduced.

[0066] Of course, in other embodiments, the receiving groove 56 may not be provided, and the elastic member 1 may rest between the inner end face 59 of the connecting block 5 and the bottom 34 of the inner cavity 3. Alternatively, when space permits, the elastic member 1 may also be a tension spring, with its two ends connected to the opening 33 of the inner cavity 3 and the outer end face 58 of the connecting block 5, respectively.

[0067] In some embodiments, to further define the deformation direction of the elastic element 1, such as... Figure 11 and Figure 14 As shown, a positioning rod 35 is also fixed at the bottom 34 of the inner cavity 3. The elastic element 1 is a spring and is sleeved on the outside of the positioning rod 35, so that the elastic element 1 can be constrained to stretch and deform in the first direction X through the positioning rod 35.

[0068] In some embodiments, to achieve a pop-out quick-release mechanism for the battery 8, such as... Figure 15 As shown, an unlocking block 53 is also fixed on the first side 55 of the connecting block 5, which can work with the locking block 52, the hook 9 and the elastic element 1 to achieve this function.

[0069] Specifically, such as Figure 14 As shown, the unlocking block 53 and the locking block 52 are arranged sequentially from top to bottom. The unlocking block 53 has an unlocking surface 531 that is inclined relative to the vertical direction (i.e., the first direction X). When the hook 9 is in the zero position, the locking end 91 is aligned with a middle portion of the unlocking surface 531 in the first direction X, as shown. Figure 14 In the middle, the locking end 91 and the unlocking surface 531 are aligned at a midpoint D between the two ends to ensure that when the connecting block 5 moves down, the locking end 91 can slide along the unlocking surface 531 to avoid the upward movement space of the locking block 52, and to ensure that the connecting block 5 can move up to the first position.

[0070] When connecting block 5 is subjected to downward pressing force, such as Figure 14 As shown, the connecting block 5 can move from the second position into the inner cavity 3. During the movement, the unlocking surface 531 can push the locking end 91 and drive the hook 9 to gradually swing around the fulcrum 41, so that the hook 9 and the locking end 91 avoid the outward movement path of the locking block 52, thereby allowing the locking block 52 to move outward after the pressing pressure is released. Figure 16 and Figure 17 As shown, the connecting block 5 can move outward to the first position under the elastic force of the elastic element 1, so that the battery 8 can pop out of the battery compartment 7 upward. Without the need for tools such as screwdrivers or solvents, the disassembly of the battery 8 is safer and more efficient.

[0071] It should be noted that during the automatic ejection of the connecting block 5, since the locking end 91 of the hook 9 passes through the gap between the unlocking block 53 and the locking block 52, to ensure that the locking end 91 does not obstruct the outward movement path of the locking block 52 during the outward movement of the connecting block 5 to the first position, this can be achieved through settings such as the elasticity of the hook elastic structure and the elasticity of the elastic element 1, and the positional relationship between the unlocking block 53 and the locking block 52. For example, if the elasticity of the hook elastic structure is less than that of the elastic element 1, the connecting block 5 will move upward at a greater speed. (Refer to...) Figures 15 to 16 In this state, the unlocking surface 531 on the right side of unlocking block 53, the right side of the gap, and the right side of locking block 52 sequentially pass through locking end 91. The path of locking end 91 relative to connecting block 5 can also be referenced. Figure 20 The dotted line in the diagram; or, if the elasticity of the hook's elastic structure is greater than that of the elastic element 1, causing the connecting block 5 to move upward at a slower speed, the locking end 91 can sequentially pass through the unlocking surface 531 on the right side of the locking block 52 and the gap to reach the left side of the locking block 52, which will not affect the upward movement of the locking block 52. In this case, the path of the locking end 91 relative to the connecting block 5 can also be referenced. Figure 21 The dashed line in the middle.

[0072] In some embodiments, such as Figure 16 As shown, on the unlocking block 53, on the first side in the second direction Y ( Figures 14 to 19 The right side (in the left-right direction) is the unlocking surface 531. The side of the locking block 52 on the first side in the second direction Y is the second guide surface 522. The second guide surface 522 is inclined relative to the first direction X, and the unlocking surface 531 and the second guide surface 522 gradually deviate towards the second side in the second direction Y along the direction close to the cavity bottom 34 of the inner cavity 3. That is, in Figure 16 In the middle, the unlocking surface 531 and the second guide surface 522 gradually shift to the left along the downward direction.

[0073] During the pop-out process of connecting block 5, unlocking block 53 first disengages from locking end 91, and then locking block 52 contacts locking end 91. Since the second guide surface 522 is also a surface that is inclined relative to the first direction X, locking end 91 can slide against the second guide surface 522 and perform a smooth reset movement, which is beneficial to extending the service life of hook 9.

[0074] In some embodiments, such as Figure 14 As shown, the locking surface 523 is on the second side in the second direction Y ( Figures 14 to 19 The left side (in the left-right direction) is the first guide surface 521, and the locking surface 523 has a locking groove 5231 at its center in the second direction Y for engaging the locking end 91. At this time, the locking block 52 is a heart-shaped block. The locking groove 5231 improves the reliable engagement between the hook 9 and the locking block 52 when the connecting block 5 is in the second position.

[0075] In some embodiments, when the hook 9 is in the zero position, the locking end 91 is aligned with an intermediate position on the first guide surface 521 in the second direction Y, such as... Figure 17 In the middle, the locking end 91 is aligned with point C to ensure that when the connecting block 5 moves down from the first position, the first guide surface 521 can push the locking end 91 of the hook 9.

[0076] Furthermore, to prevent the connecting block 5 from detaching from the housing 2, such as Figure 10 , Figure 12 and Figure 13 As shown, a limiting block 54 is fixed on one side of the connecting block 5, for example, it is disposed on the first side 55. A limiting hole 24 extending along the first direction X is provided on the housing 2. The limiting block 54 extends into the limiting hole 24, specifically along the third direction Z, and can slide within the limiting hole 24 in the first direction X. Figure 13 As shown, when the connecting block 5 is in the first position, the side of the limiting block 54 away from the bottom 34 of the cavity 3 in the first direction X abuts against the wall of the limiting hole 24, thereby preventing the connecting block 5 from completely coming out of the housing 2.

[0077] In some embodiments, such as Figure 10 As shown, the connecting block 5 has a first side surface 55 on one end face in the third direction Z, and the first side surface 55 has a stepped structure. The stepped structure includes a first surface 551 that fits against the side wall of the inner cavity 3 in the second direction Y, and a second surface 552 that is spaced apart from the side wall of the inner cavity 3. The stepped structure also includes a third surface located between the first surface 551 and the second surface 552. There are corners between the first surface 551, the third surface, and the second surface 552, thus forming a stepped structure.

[0078] The first surface 551 fits against the inner wall of the inner cavity 3 of the housing 2, which can improve the stability of the connecting block 5 sliding in the inner cavity 3 of the housing 2. The limiting block 54 is fixed on the first surface 551. There is a gap between the second surface 552 and the inner wall of the inner cavity 3, specifically in the third direction Z. The locking block 52 is provided on the first surface 551 and can be accommodated in the gap, ensuring that the locking block 52 can slide along the first direction X with the connecting block 5 without being interfered with by the housing 2.

[0079] Furthermore, to achieve a snap-fit ​​connection with battery 8, such as Figure 14 and Figure 17 As shown, the snap-fit ​​structure 6 includes at least two elastic latches 61, for example, two latches arranged sequentially in the second direction Y. One end of each latch 61 in the first direction X is connected to the outer end face 58, and the other end is a free end.

[0080] In addition, such as Figure 9 , Figure 11 and Figure 12As shown, the shell wall of the housing 2 includes a first annular shell 21, a middle annular plate 23 and a second annular shell 22 in sequence along the direction away from the cavity bottom 34. The inner circumference of the middle annular plate 23 is connected to the first annular shell 21 and the outer circumference is connected to the second annular shell 22, so that the housing forms a stepped shell. The middle annular plate 23 can be perpendicular to the first direction X.

[0081] At this time, in the inner cavity 3, as Figure 11 As shown, the sidewall of the inner cavity 3 includes, along the cavity bottom 34 away from the inner cavity 3, a first inner cavity sidewall 31 inside the first annular shell 21, a second inner cavity sidewall 32 inside the second annular shell 22, and an inner stepped surface 232 between the first inner cavity sidewall 31 and the second inner cavity sidewall 32, located on the first annular shell 21 and facing the inner cavity 3, so that the sidewall of the inner cavity 3 forms a stepped surface.

[0082] like Figure 14 As shown, when the connecting block 5 is in the second position, the portion of the first annular shell 21 near the middle annular plate 23 can press the claws 61, mainly by pressing the first inner cavity sidewall 31, so that the free ends of each claw 61 come closer together, cooperating to lock the battery 8 in place by the locking block 81. Figure 17 As shown, when the connecting block 5 is in the first position, each claw 61 is completely disengaged from the inner cavity 3 and moves away from each other under the action of the elastic restoring force, so that the claw 61 releases the battery 8's locking block 81 and avoids the path of the locking block 81 away from the connecting block 5 in the first direction X, ensuring that the battery 8 is disassembled smoothly. At this time, the movement control of the claw 61 is realized through the stepped inner cavity 3.

[0083] Alternatively, after each claw 61 is completely disengaged from the inner cavity 3, it may remain relatively close to or only slightly away from the claw, maintaining at least partially engaged with the locking block 81. In this case, when the battery 8 is subjected to external pulling force, the locking block 81 pushes open the claws 61, enabling the battery 8 to be disassembled without affecting its normal disassembly. During the next installation of the battery 8, the locking block 81 can correspondingly push open the free ends of each claw 61 to enter between them. In this case, the claws 61 are configured as elastic elements, primarily for the purpose of... Figure 13 As shown, when the claw 61 extends out of the housing 2, it can be fixed in shape by its own reset action and will not swing or shift at will, which facilitates the reassembly of the battery 8.

[0084] In addition, the surface of the middle annular plate 23 located outside the housing 2 forms an outer stepped surface 231 outside the housing 2. When the housing 2 is installed in the battery compartment 7, the first annular shell 21 is inserted into the slot at the bottom of the battery compartment 7 along the first direction X, and is limited by the outer stepped surface 231 abutting against the bottom of the battery compartment 7.

[0085] Of course, in other embodiments, the snap-fit ​​structure 6 can also achieve the release and gripping action without the help of the housing 2. For example, the claw 61 is hinged to the connecting block 5. When the battery 8 approaches the hinge end of the claw 61, the free end of the claw 61 is brought close to the snap-fit ​​block 81 to hold the battery 8 by pressing the hinge end of the claw 61, thereby achieving snap-fit ​​fixation.

[0086] In some embodiments, such as Figure 9 and Figure 10 As shown, a pressing block 51 is also provided on the outer end face 58 of the connecting block 5, and each claw 61 is arranged around the pressing block 51. When the battery 8 is installed in the battery compartment 7, the claw 81 can press the pressing block 51 to push the connecting block 5 into the inner cavity 3.

[0087] Furthermore, to achieve the assembly of hook 9, such as Figure 11 As shown, a fixing rod 4 is provided in the housing 2. The fixing rod 4 and the bottom 34 of the inner cavity 3 have an installation gap 42 in the first direction X. The fulcrum 41 is located on the side of the fixing rod 4 facing the bottom 34 of the inner cavity 3. The hook 9 can be connected to the fulcrum 41 through the installation gap 42, which is convenient for installation.

[0088] In some embodiments, to achieve an elastic connection between the hook 9 and the fulcrum 41, the hook 9 is selected as an elastic hook, that is, the hook 9 as a whole is elastic. In this case, the elastic structure of the hook can be regarded as a part of the hook 9 near the fulcrum 41. Optionally, the hook 9 is a metal hook. The elastic hook can be formed by bending an elastic rod. For example, the two ends of the middle section 93 of the elastic rod are first bent relative to each other to form two first rod sections 92, and the ends of the two first rod sections 92 are then bent relative to each other to form two locking ends 91.

[0089] At this time, the hook 9 can be fixed to the fulcrum 41, for example, by snapping it into the hook groove on the fixed rod 4. The angle at which the hook 9 is fixed to the fulcrum 41 corresponds to its zero position relative to the fulcrum 41. When the hook 9 swings relative to the fulcrum 41, it will have a tendency to return to the zero position.

[0090] Alternatively, a torsion spring can be used for the hook elastic structure. The hook 9 is rotatably connected to the fulcrum 41, and the hook 9 is connected to the fulcrum 41 through the torsion spring. This can also achieve the setting of the hook elastic structure and the elastic connection between the hook 9 and the fulcrum 41.

[0091] In some embodiments, such as Figure 9 As shown, the two end faces of the connecting block 5 in the third direction Z are both first side faces 55. Correspondingly, each of the two first side faces 55 is provided with a locking block 52 and an unlocking block 53. The hook 9 includes two locking ends 91, which are respectively locked or unlocked with the locking blocks 52 and unlocking blocks 53 on the two first side faces 55, which can improve the stability of the hook 9 locking the connecting block 5.

[0092] Based on this, in order to improve the stability of the connection of hook 9, two fixing rods 4 are arranged in sequence along the third direction Z, and the middle section 93 of hook 9 is connected to the two fixing rods 4.

[0093] In some embodiments, when the connecting block 5 moves into the inner cavity 3, it can be limited by the fixing rod 4, and can move up to abut against the fixing rod 4, thereby achieving the limitation by the fixing rod 4.

[0094] Furthermore, the battery connection module also includes a battery 8, one end of which has a locking block 81 for engaging with the locking structure 6. Additionally, as... Figure 7 As shown, a sleeve 83 is also provided on the battery 8, located on the outer periphery of the locking block 81. The sleeve 83 is fitted onto the outer side of one end of the housing 2 in the first direction X, specifically on the outer side of the second annular shell 22, to further increase the constraint structure on the battery 8 and improve the reliability of the connection. In addition, in the battery compartment 7, since the sleeve 83 engages with the housing 2 when the battery 8 moves inward to near the bottom of the compartment, it also forms a limiting force, further restricting the battery 8 to move only in the first direction X.

[0095] In this embodiment of the application, when the battery connection module is applied to an electrical device, the battery connection module is located in the battery compartment 7 of the electrical device, and the principle of installing and removing the battery 8 includes:

[0096] When installing battery 8 into battery compartment 7, the battery connection module is initially in the following state: Figure 17 The states shown are referred to in sequence. Figure 17 , Figure 18 , Figure 19 , Figure 14 Following the correct orientation and sequence, battery 8 is aligned with the opening of battery compartment 7 and slowly inserted downwards towards the bottom of battery compartment 7. The locking block 81 on battery 8 is located on the bottom surface of battery 8 facing the bottom of battery compartment 7, continuously approaching the locking structure 6. When the locking block 81 presses against the pressing block 51, it pushes the connecting block 5 downwards. In the battery connection module, the locking block 52 moves downwards, and the hook 9 continuously swings against the second guide surface 522 on the left side of the locking block 52. The locking end 91 moves to the left, as... Figure 14 As shown, when the connecting block 5 moves down to the second position, the snap-fit ​​structure 6 clamps the snap-fit ​​block 81 under the pressure of the side wall of the inner cavity 3, and the locking block 52 moves into place with the connecting block 5. The locking end 91 of the hook 9 blocks the locking surface 523 on the locking block 52, thus completing the installation of the battery 8.

[0097] When it is necessary to remove battery 8, in the initial state, the battery connection module is in... Figure 14 The states shown are referred to in sequence. Figure 14 , Figure 15 , Figure 16 , Figure 17Following the user's direction and sequence, the user presses the top surface of the battery 8. The connecting block 5 causes the unlocking block 53 and locking block 52 to move downwards simultaneously. The locking end 91 of the hook 9 disengages from the locking surface 523 and swings to the right under the push of the unlocking surface 531. After releasing the battery 8, the connecting block 5 moves upwards under the reset action of the elastic element 1. During this process, the locking end 91 of the hook 9 passes sequentially through the unlocking surface 531, the gap between the unlocking block 53 and the locking block 52, and the second guide surface 522. The locking block 52 then moves above the locking end 91 until... Figure 17 and Figure 13 At the position shown, the connecting block 5 and the battery 8 are popped out by the elastic element 1 and eventually move to the position where the limiting block 54 and the limiting hole 24 are limited. The snap-fit ​​structure 6 is no longer constrained by the inner cavity 3, and the elastic reset opening movement releases the snap-fit ​​block 81 of the battery 8, realizing the pop-up quick release of the battery 8, so that the user can easily take out the battery 8.

[0098] In addition to the aforementioned battery connection module, this utility model also provides an electronic device that includes a battery connection module. Specifically, the battery connection module can be any of the battery connection modules provided in the above embodiments, and the beneficial effects can be referred to the respective embodiments above. Using this battery connection module eliminates the need for screws to secure the battery 8, greatly improving the convenience of battery 8 disassembly and installation, reducing the risk of malfunctions caused by screw issues, enhancing user experience and the maintenance efficiency of the electronic device, and improving the user's overall experience.

[0099] The electronic device also includes a casing and a battery 8. For example... Figures 1 to 8 As shown, the battery 8 is provided with a locking block 81, which is used to engage with the locking structure 6 on the connecting block 5.

[0100] In some embodiments, such as Figure 8 and Figure 9 As shown, the electronic device has a battery compartment 7 on its casing. The compartment opening is located at one end of the battery compartment 7 in the first direction X, and the bottom is located at the other end. The bottom of the battery compartment 7 is fixedly connected to the casing 2, and as shown... Figure 7 and Figure 8 As shown, in the first direction X, the bottom 34 of the inner cavity 3 and the connecting block 5 are arranged sequentially along the direction close to the compartment opening. At this time, the opening 33 of the inner cavity 3 faces the compartment opening of the battery compartment 7. The battery 8 can enter the battery compartment 7 through the compartment opening along the first direction X, and the locking block 81 on the battery 8 can be connected to the locking structure 6.

[0101] In some embodiments, such as Figure 6 and Figure 7 As shown, multiple locking blocks 81 are provided on one end face of the battery 8 in the first direction X to improve the anti-drop effect. For example, two battery connection modules are located at the bottom of the battery compartment 7 to connect to the two locking blocks 81 respectively, so as to ensure the reliability of the connection.

[0102] In addition, such as Figure 6 As shown, on the end face of the battery 8 with the mounting block 81, the electrical connector 82 can be disposed between the two mounting blocks 81, thereby fixing the battery 8 and the battery compartment 7 from both sides of the electrode respectively, ensuring the reliability of the electrical connection.

[0103] In some embodiments, the sidewalls of the battery compartment 7 limit the sides of the battery 8 in directions perpendicular to the first direction X, so that the battery 8 has only the first direction X as a degree of freedom of movement within the battery compartment 7. In this case, the sidewalls of the battery compartment 7 form limiting guides, which, together with the battery connection module, enable the battery 8 to be fixed in all directions within the battery compartment 7.

[0104] It should be noted that the limiting of the battery compartment 7 on the battery 8 specifically refers to limiting the distance within the allowable assembly gap range. This can be achieved by ensuring consistency in the dimensions of the battery 8 and the battery compartment 7 perpendicular to the first direction X. For example, the side wall of the battery compartment 7 can fit perfectly against the side of the battery 8, or a small gap can be reserved between the side wall of the battery compartment 7 and the side of the battery 8, taking a value within the allowable assembly gap range, such as a value not greater than 0.2mm.

[0105] For example, such as Figure 1 and Figure 2 As shown, the battery compartment 7 is a square compartment. The sidewalls of the battery compartment 7 include two first compartment sidewalls arranged sequentially along the second direction Y and two second compartment sidewalls arranged sequentially along the third direction Z. The two first compartment sidewalls and the two second compartment sidewalls respectively fit and cooperate with the sidewalls of the battery 8 in the corresponding directions. In other embodiments, when the battery 8 is cylindrical, the battery compartment 7 can also be a cylindrical compartment.

[0106] In some embodiments, the electronic device is specifically a laptop computer, with the battery compartment 7 disposed on its system-side casing. The laptop computer also includes a display terminal movably connected to the system-side, with a keyboard, touchpad, and other structures disposed on the system-side, and a display panel disposed on the display terminal. In other embodiments, the electronic device may be other devices, such as a remote control, tablet computer, portable medical device, etc.

[0107] In some embodiments, the card block 81 may be a plastic block or a metal block.

When an element is referred to as "connecting" another element, it can be directly connected to the other element or there may be an intervening element.
