Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a charging base and battery module. Background Technology

[0002] For electronic devices, rechargeable batteries are typically designed to power them and maintain continuous operation. To facilitate battery charging, a common approach is to mount the battery in a charging dock. However, using a charging dock can be cumbersome, making the process of attaching and detaching the battery from the dock inconvenient. Utility Model Content

[0003] This utility model provides a charging base and a battery module, which can improve the convenience of installing the battery and the charging base.

[0004] In a first aspect, this utility model provides a charging base, comprising:

[0005] The base body has a charging receiving slot on at least one side for connecting to a battery with a charging connection part, the charging connection part being detachably installed in the charging receiving slot.

[0006] A first connection terminal group, one end of which protrudes from the bottom of the charging receiving groove for electrical connection with the charging connection part, and the other end of which is used for connection with a power source.

[0007] A limiting module, the limiting module including an anti-rotation shaft passing through the bottom of the charging receiving groove, the anti-rotation shaft being used to cooperate with a limiting hole provided in the charging connection part to limit the rotation of the charging connection part around the axis of the base body;

[0008] A drive module is used to drive the anti-rotation shaft to disengage from the charging connection when the anti-rotation shaft is located within the limiting hole.

[0009] The charging base of this invention features a charging receiving slot for battery installation. When the battery needs charging, the first connection terminal group can be connected to a power source to achieve charging. When installing the battery onto the charging base, the battery's charging connection can be placed into the charging receiving slot, allowing the anti-rotation shaft to be inserted into the limiting hole of the charging connection, thereby restricting the battery's rotation relative to the charging receiving slot and achieving relative fixation between the battery and the charging base. When the battery needs to be removed, the anti-rotation shaft can be driven by the drive module to disengage from the limiting hole, releasing the restriction between the battery and the charging receiving slot, facilitating the removal of the battery from the charging base. This charging base utilizes the anti-rotation shaft and drive module to achieve convenient and efficient battery installation and removal.

[0010] In some possible implementations, the base body has an internal accommodating space located at the bottom of the charging receiving slot. An elastic element is provided within the accommodating space. One end of the anti-rotation shaft is located within the accommodating space and connected to the elastic element. The elastic element can extend and retract along the axial direction of the base body to drive the anti-rotation shaft to move relative to the charging receiving slot along the axial direction of the base body.

[0011] In some possible implementations, the drive module includes:

[0012] A first wedge block is disposed in the accommodating space and is movably disposed along the axial direction of the base body. The first wedge block is fixedly connected to the anti-rotation shaft, and the side of the first wedge block facing the charging accommodating groove has a first inclined surface.

[0013] The second wedge has a second inclined surface, which is partially attached to the first inclined surface. The second wedge is movable relative to the first wedge along the extension direction of the first inclined surface.

[0014] In some possible implementations, the drive module further includes a pressing part;

[0015] The base body is also provided with a pressing groove, the axis of which is perpendicular to the axis of the charging receiving groove. The pressing part is movably installed in the pressing groove relative to the axial direction of the pressing groove, and the pressing part is connected to the second wedge block.

[0016] In some possible implementations, the charging receiving slots are respectively provided on opposite sides of the base body, and the two charging receiving slots are located at opposite ends of the accommodating space;

[0017] The two ends of the elastic element are respectively connected to the anti-rotation shafts on both sides.

[0018] In some possible implementations, the limiting module further includes a plurality of limiting tongues, which are disposed at the opening of the charging receiving groove. Each limiting tongue protrudes radially from the inner wall of the charging receiving groove, and any two adjacent limiting tongues are spaced apart.

[0019] Along the axial direction of the base body, the limiting tongue is spaced apart from the bottom wall of the charging receiving groove. The limiting tongue is used to cooperate with the charging receiving groove to limit the protrusions that are spaced apart circumferentially along the charging connection part in the axial direction of the battery.

[0020] In some possible implementations, a limiting block is connected to the side of the limiting tongue facing the bottom of the charging receiving groove. The limiting block is located on one of the two sides of the limiting tongue along the circumference of the charging receiving groove and is used to abut against the protrusion.

[0021] In some possible implementations, the bottom of the charging receiving slot is provided with a first magnetic attraction component, which is used to attract each other with a second magnetic attraction component disposed on the charging connection portion.

[0022] In some possible implementations, the first connection terminal group includes a first charging and discharging terminal and a second charging and discharging terminal, the first charging and discharging terminal and the second charging and discharging terminal being distributed circumferentially along the charging receiving groove, and the first charging and discharging terminal and the second charging and discharging terminal being respectively used to connect to the positive terminal and the negative terminal disposed on the charging connection portion.

[0023] There are at least two charging reservoirs, and the first charging and discharging terminals in each charging reservoir are connected in parallel, and the second charging and discharging terminals in each charging reservoir are connected in parallel.

[0024] In a second aspect, the present invention provides a battery module, including a battery and a charging base as described in any possible embodiment of the first aspect;

[0025] The battery is provided with a charging connection part, and the charging connection part is provided with a limiting hole. The limiting hole is used to cooperate with the anti-rotation shaft to restrict the battery from rotating around the axis of the base body. Attached Figure Description

Detailed Implementation

[0037] 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.

[0038] To facilitate the charging of batteries in electronic devices and the disassembly and assembly of batteries with charging bases, this utility model provides a charging base and battery module that facilitates charging and battery replacement, thereby improving the user experience of electronic devices.

[0039] refer to Figure 1 The battery module in this embodiment may include a charging base 100 and a battery 200, with the battery 200 mounted on the charging base 100.

[0040] refer to Figure 1 and Figure 2 The charging base 100 in this embodiment of the present invention may include a base body 110, and a charging receiving groove 120 is provided on at least one side of the base body 110. The charging receiving groove 120 can be used to install a battery 200 for charging and discharging the battery 200.

[0041] In practical applications, the charging base 100 in this embodiment can be used to charge and discharge the cylindrical battery 200. Correspondingly, the base body 110 can also be a cylindrical structure. In this case, two charging receiving slots 120 are disposed on both sides of the base body 110 along the axial direction.

[0042] Please refer to the above. Figure 2 and Figure 3 The battery 200 may include a battery body 210 and a charging connection portion 220 connected to the bottom of the battery body 210. The charging connection portion 220 protrudes from the surface of the battery body 210 so that it can be installed in the charging receiving slot 120 to complete the charging operation of the charging base 100 and the battery 200. In this embodiment, the charging connection portion 220 and the charging receiving slot 120 are detachably connected. When the battery 200 needs to be charged, the battery 200 can be assembled with the charging base 100. When the battery 200 needs to be replaced, the battery 200 can be separated from the charging base 100 to facilitate the charging of other batteries 200.

[0043] refer to Figures 2 to 4 The charging base 100 may further include a first connection terminal group 140, one end of which may protrude from the bottom of the charging receiving groove 120. A second connection terminal group 240 is provided at the bottom of the charging connection part 220. The charging connection part 220 may extend into the charging receiving groove 120 through its opening, thereby electrically connecting the first connection terminal group 140 and the second connection terminal group 240 to achieve connection between the battery 200 and the charging base 100.

[0044] The other end of the first connection terminal group 140 can be used to connect to a power source or electronic device. When the first connection terminal group 140 is connected to a power source, the battery 200 can be charged using the power source. When the first connection terminal group 140 is connected to an electronic device, the battery can supply power to the electronic device to ensure its normal operation.

[0045] Specifically, such as Figure 2 and Figure 4As shown, the first connection terminal group 140 may include a first charge / discharge terminal 141 and a second charge / discharge terminal 142, which are spaced apart circumferentially along the charging receiving groove 120. The second connection terminal group 240 includes a positive connection terminal 241 and a negative connection terminal 242, whereby the first charge / discharge terminal 141 can be connected to the positive connection terminal 241, and the second charge / discharge terminal 142 can be connected to the negative connection terminal 242.

[0046] The base body 110 may be provided with a connection port 150, and the first charge / discharge terminal 141 and the second charge / discharge terminal 142 are respectively connected to the connection port 150. The connection port 150 can be used to connect to a power source or electronic device. When the connection port 150 is connected to a power source, the battery 200 can be charged. When the connection port 150 is connected to an electronic device, the battery 200 can be used to power the electronic device.

[0047] As mentioned above, the base body 110 is provided with at least one charging receiving slot 120. When the number of charging receiving slots 120 is greater than or equal to 2, the first charging and discharging terminals 121 in each charging receiving slot 120 can be connected in parallel, and the second charging and discharging terminals 142 in each charging receiving slot 120 can be connected in parallel. That is to say, when two batteries 200 are respectively installed in two charging receiving slots 120, the charging and discharging of the two batteries 200 are relatively independent.

[0048] Based on this, Figure 1 Taking the charging dock 100 shown as an example with two batteries 200 installed, when using the batteries 200 to power the electronic device, one battery 200 can be used initially. When the power of that battery 200 is insufficient, the charging dock 100 can automatically switch the connection port 150 to the other connected battery 200. In this way, by setting at least two batteries 200 to continuously power the electronic device, the battery life of the electronic device can be improved, thereby enhancing the practicality of the electronic device.

[0049] In addition, it is worth mentioning that, still based on Figure 1 For example, since the two batteries 200 independently power the electronic device, when one battery 200 is powering the electronic device, if the other battery 200 needs to be replaced, the battery 200 to be replaced can be directly removed from the charging base 100, and the new battery 200 can be installed in the charging base 100. That is, the electronic device does not need to be powered off when replacing the battery 200, thus enabling the hot-swappable function of the battery 200.

[0050] In the above embodiments, refer again Figure 2The first charging / discharging terminal 141 and the second charging / discharging terminal 142 disposed in the charging receiving slot 120 can both be in the form of pins. In this case, the first charging / discharging terminal 141 and the second charging / discharging terminal 142 protrude from the bottom of the charging receiving slot 120 so as to facilitate quick connection with the battery 200.

[0051] In practice, multiple pins can be provided on both the first charging / discharging terminal 141 and the second charging / discharging terminal 142, which can improve the stability of the connection between the charging connection part 220 and the charging receiving slot 120.

[0052] The base body 110 can also be equipped with indicator lights that correspond one-to-one with the two charging slots 120. The indicator lights can be used to display the power level of the corresponding battery 200, so that users can check the power level of the battery 200 at any time during charging and use, thereby improving the convenience of using electronic devices.

[0053] Based on this, refer to Figure 3 and Figure 4 The first connection terminal group 140 may also include a first signal connection terminal 143, and the second connection terminal group 240 may also include a second signal connection terminal 243. When the charging connection part 220 is located at the second working position, the first signal connection terminal 143 and the second signal connection terminal 243 are electrically connected to achieve the display effect of the indicator light.

[0054] The first signal connection terminal 143 can also be arranged circumferentially between the first charge / discharge terminal 141 and the second charge / discharge terminal 142 along the charging receiving groove 120. Furthermore, the first signal connection terminal 143 can also be in the form of a pin to facilitate quick connection with the second signal connection terminal 243.

[0055] In some embodiments, refer again Figures 2 to 4 The charging base 100 may also include a limiting module 130. When the battery 200 is assembled with the charging base 100, the limiting module 130 can limit the battery 200 to ensure the fixing effect between the charging base 100 and the battery 200.

[0056] The limiting module 130 may include multiple limiting tongues 131, which are spaced apart circumferentially at the opening of the charging receiving groove 120. Each limiting tongue 131 protrudes radially from the inner wall of the charging receiving groove 120. The limiting tongues 131 are spaced apart from the bottom of the charging receiving groove 120 along the axial direction of the base body 110.

[0057] Correspondingly, the charging connector 220 is provided with protrusions 250 corresponding one-to-one with the plurality of limiting tongues 131. The circumferential dimension of the protrusion 250 is smaller than the dimension between two adjacent limiting tongues 131, and the protrusion 250 protrudes radially from the edge of the charging connector 220. When assembling the battery 200 with the charging base 100, the charging connector 220 can be inserted into the charging receiving groove 120 first. At this time, each protrusion 250 is located in the space between two adjacent limiting tongues 131. Subsequently, the battery 200 can be rotated so that the protrusion 250 enters the bottom of the limiting tongue 131, and the two sides of the protrusion 250 abut against the limiting tongue 131 and the bottom of the charging receiving groove 120, respectively. At this time, the limiting tongue 131 cooperates with the charging receiving groove 120 to limit the charging connection part 220 in the axial direction of the battery 200, so that the charging connection part 220 is fixed between the charging base 100 in the axial direction.

[0058] like Figure 2 As shown, a limiting block 1311 can also be provided on the side of the limiting tongue 131 facing the bottom of the charging receiving groove 120. The limiting block 1311 can be connected to the limiting tongue 131 and the bottom wall of the charging receiving groove 120 respectively. When the charging connection part 220 is in the second working position, the side of the charging connection part 220 can also abut against the limiting block 1311, so that the limiting block 1311 can limit the rotation angle of the charging connection part 220, thereby achieving the effect of positioning the charging connection part 220.

[0059] The limiting block 1311 is only provided on one of the two sides of the limiting tongue 131 along the circumference of the charging receiving groove 120. In this way, when the other side of the limiting tongue 131 is not provided with the limiting block 1311, the charging connection part 220 can easily enter the space between the limiting tongue 131 and the bottom wall of the charging receiving groove 120 when the charging connection part 220 is rotated from the first station to the second station.

[0060] In some embodiments, continue to refer to Figures 2 to 4 The limiting module 130 may also include an anti-rotation shaft 132 disposed at the bottom of the charging receiving groove 120. Correspondingly, the charging connection part 220 is provided with a limiting hole 230. When the protrusion 250 abuts against the limiting tongue 131 and the bottom of the charging receiving groove 120, the anti-rotation shaft 132 is located in the limiting hole. At this time, the anti-rotation shaft 132 cooperates with the limiting hole 230 to limit the charging connection part 220 in the rotation direction, so as to prevent the charging connection part 220 from rotating relative to the charging receiving groove 120.

[0061] In this embodiment, the anti-rotation shaft 132 can move relative to the charging receiving groove 120 along the axial direction of the base body 110 to change the height of the anti-rotation shaft 132 protruding from the bottom of the charging receiving groove 120. Specifically, the anti-rotation shaft 132 may have a first working position and a second working position. When the anti-rotation shaft 132 is in the first working position, the height of its protrusion from the bottom of the charging receiving groove 120 is less than the height of its protrusion from the bottom of the charging receiving groove 120 when the anti-rotation shaft 132 is in the second working position. When the anti-rotation shaft 132 is in the second working position, it is used to extend into the limiting hole 230 to cooperate with the limiting hole 230 in rotating the charging connection portion 220 around the axis of the base body 110.

[0062] Understandably, when the anti-rotation shaft 132 is in the first position, the end of the anti-rotation shaft 132 can be approximately flush with the bottom surface of the charging receiving groove 120, so that the charging connection part 220 can rotate relative to the charging receiving groove 120. When the protrusion 250 is located at the bottom of the limiting tongue 131, the end of the anti-rotation shaft 132 protrudes from the bottom wall of the charging receiving groove 120, so that the anti-rotation shaft 132 can extend into the limiting hole 230 and cooperate with the limiting hole 230 to limit the charging connection part 220.

[0063] Furthermore, the base body 110 also has an internal accommodating space located at the bottom of the charging receiving slot 120. A circuit board can be installed inside the accommodating space, and the first connection terminal group 140 provided in the charging receiving slot 120 is connected to the circuit board to realize different functional controls.

[0064] As an optional implementation scheme, refer to Figure 5 The anti-rotation shaft 132 can be inserted through the bottom of the charging receiving groove 120, so that a part of the anti-rotation shaft 132 is located inside the receiving space. An elastic member 160 is provided in the receiving space. The elastic member 160 is connected to one end of the anti-rotation shaft 132 located in the receiving space. The elastic member 160 can extend and retract along the axial direction of the base body 110 to drive the anti-rotation shaft 132 to move relative to the bottom of the charging receiving groove 120, thereby changing the height of the anti-rotation shaft 132 protruding from the bottom of the charging receiving groove 132.

[0065] When pressure is applied to one end of the anti-rotation shaft 132 located within the charging receiving groove 120, the end of the anti-rotation shaft 132 located within the charging receiving groove 120 can move toward the receiving space. During this process, the elastic member 160 is subjected to compressive force and is compressed. When the pressure on the end of the anti-rotation shaft 132 is removed, during the recovery process of the elastic member 160, the elastic member 160 can drive the anti-rotation shaft 132 to extend out of the bottom wall of the charging receiving groove 120.

[0066] Understandably, when the elastic element 160 is in its initial state, the anti-rotation shaft 132 is in the second position, with its end protruding from the bottom of the charging receiving groove 120. When the battery 200 is installed with the charging base 100, the charging connection 220 is placed in the charging receiving groove 120, the protrusion 150 is located between two adjacent limiting tongues 131, and the anti-rotation shaft 132 is not aligned with the limiting hole 230. Under the squeezing action of the charging connection 220, the anti-rotation shaft 132 moves toward the interior of the receiving space until its end is approximately flush with the bottom surface of the charging receiving groove 120. When the charging connection 220 rotates to the point where the protrusion 250 is below the limiting tongue 131, the anti-rotation shaft 132 is aligned with the limiting hole 230, the pressure applied to the anti-rotation shaft 132 disappears, and under the drive of the elastic member 160, the anti-rotation shaft 132 springs back and extends into the limiting hole 230.

[0067] To ensure the effective fixation between the anti-rotation shaft 132 and the limiting hole 230, the depth of the limiting hole 230 can be designed so that when the end of the anti-rotation shaft 132 abuts against the top of the limiting hole 230, the elastic member 160 remains in a compressed state. In this state, the anti-rotation shaft 132 always maintains a tendency to move towards the charging connection portion 220, thereby ensuring a good fixation effect between the anti-rotation shaft 132 and the limiting hole 230 in the axial direction.

[0068] In some embodiments, reference Figure 6 To facilitate the removal of the battery 200 from the charging base 100, the charging base 100 may further include a drive module 170. The drive module 170 can be used to drive the anti-rotation shaft 132 to disengage from the charging connection part 220. That is, the drive module 170 can be used to drive the elastic member 160 to extend and retract along the axial direction of the anti-rotation shaft 132, so that the anti-rotation shaft 132 can disengage from the limiting hole 230.

[0069] Based on this, the drive module 170 may include a mounting plate 171, a first wedge block 172, and a second wedge block 173. The mounting plate 171 can be fixed within the accommodating space, and the first wedge block 172 is connected to the mounting plate 171. Figure 1 Taking the battery module shown as an example, when batteries 200 are installed on opposite sides of the charging base 100, the mounting plates 171 on both sides can be an integrated structure, that is, the two first wedge blocks 172 share one mounting plate 171.

[0070] The first wedge blocks 172 on both sides are spaced apart, and the elastic element 160 is located between the two first wedge blocks 172, with both ends of the elastic element 160 fixedly connected to the two first wedge blocks 172 respectively. The first wedge blocks 172 are fixedly connected to the two anti-rotation shafts 132. The first wedge blocks 172 can move relative to the mounting plate 171 along the axial direction of the anti-rotation shafts 132 to change the distance between the first wedge blocks 172 and the charging receiving groove 120. Since the anti-rotation shafts 132 are fixedly connected to the first wedge blocks 172, when the first wedge blocks 172 move, they can drive the anti-rotation shafts 132 to move synchronously.

[0071] To enable relative movement between the first wedge block 172 and the mounting plate 171, the mounting plate 171 may, for example, be provided with a sliding hole extending axially along the anti-rotation shaft 132. The first wedge block 172 can be mounted in the sliding hole by a slider so that the first wedge block 172 can slide relative to the mounting plate 171 along the axial direction of the anti-rotation shaft 132.

[0072] like Figure 6 As shown, the first wedge block 172 has a first inclined surface on the side facing the charging receiving groove 120. Along the axial direction of the anti-rotation shaft 132, the distance between the end of the first inclined surface near the mounting plate 171 and the charging receiving groove 120 is smaller than the distance between the end of the first inclined surface away from the mounting plate 171 and the charging receiving groove 120.

[0073] The second wedge block 173 is located on the side of the first wedge block 172 facing away from the mounting plate 171. The side of the second wedge block 173 facing the first wedge block 172 has a second inclined surface, which partially fits against the first inclined surface. Furthermore, the second wedge block 173 can move relative to the first wedge block 172 along the extending direction of the first inclined surface to apply a compressive force to the first wedge block 172, allowing the first wedge block 172 to move away from the charging receiving groove 120, thereby driving the anti-rotation shaft 132 to move away from the charging connection portion 220.

[0074] Continue to refer to Figure 6 The drive module 170 may also include a pressing part 174. The base body 110 is also provided with a pressing groove 111, the axial direction of which is perpendicular to the axial direction of the charging receiving groove 120. That is, the charging receiving groove 120 extends axially along the base body 110, and the pressing groove 111 extends radially along the base body 110. The pressing part 174 is movably mounted in the pressing groove 111 relative to the axial direction of the pressing groove 111 and is connected to the second wedge block 173. Exemplarily, the second wedge block 173 may be provided with a slot 1732, which passes through the side wall of the base body 110. A locking block 1741 is provided on the side of the pressing part 174 facing the second wedge block 173, and the locking block 1741 is locked in the slot 1732 to fix the pressing part 174 to the second wedge block 173.

[0075] It is worth noting that, Figure 6 The state shown by the pressing part 174 on the left side can be understood as the state when the charging connection part 220 is in the second position. At this time, the anti-rotation shaft 132 protrudes a relatively high height from the bottom wall of the charging receiving groove 120. Figure 6 The state shown by the pressing part 174 on the right side can be understood as the state when the battery 200 is removed from the charging receiving groove 120. At this time, the end face of the anti-rotation shaft 132 is almost flush with the bottom wall of the charging receiving groove 120.

[0076] Since the first wedge block 172 and the second wedge block 173 are in contact through the first inclined surface and the second inclined surface, when the pressing part 174 is pressed, the pressing part 174 can drive the second wedge block 173 to move toward the mounting plate 171. In the process, the second wedge block 173 can apply a force to the first wedge block 172 along the axis of the anti-rotation shaft 132, thereby driving the first wedge block 172 to move along the axis of the anti-rotation shaft 132.

[0077] When the anti-rotation shaft 132 is in the second position, there is a certain gap between the pressing part 174 and the bottom wall of the pressing groove 111 to provide space for the pressing part 174 to move. When the anti-rotation shaft 132 is in the first position, the pressing part 174 can contact the bottom wall of the pressing groove 111 to limit the travel of the pressing part 174 and prevent the anti-rotation shaft 132 from completely entering the receiving space.

[0078] In addition, continue to refer to Figure 6 A protrusion 1731 protruding from the second wedge 173 may be provided on the side of the charging receiving groove 120 facing the second wedge 173. A stop portion 121 may be provided on the side of the charging receiving groove 120 facing the second wedge 173. The stop portion 121 and the protrusion 1731 are arranged along the moving direction of the pressing portion 174, with the protrusion 1731 located on the side of the stop portion 121 facing the mounting plate 171. When the anti-rotation shaft 132 is fixed in the limiting hole 230, the protrusion 1731 and the stop portion 121 abut against each other, so that the second wedge 173 and the base body 110 remain relatively fixed, preventing the pressing portion 174 from shaking relative to the base body 110.

[0079] Specifically, when removing the battery 200 from the charging base 100, the user can apply pressure to the pressing part 174 to drive the second wedge block 173 to move, thereby squeezing the first wedge block 172 and causing the first wedge block 172 to move away from the charging receiving groove 120, thereby driving the anti-rotation shaft 132 to disengage from the limiting hole 230. Then, the charging connection part 220 is rotated, causing the protrusion 250 to move from below the limiting tongue 131 to between two adjacent limiting tongues 131. Finally, the charging connection part 220 is separated from the charging receiving groove 120, thereby realizing the removal of the battery 200.

[0080] When the battery 200 is removed, the pressure applied to the pressing part 174 disappears, and under the drive of the elastic member 160, the anti-rotation shaft 132 protrudes again from the bottom wall of the charging receiving groove 120. At the same time, the pressing part 174 returns to its original position.

[0081] In some embodiments, a first magnetic component 180 may be provided at the bottom of the charging receiving slot 120, and a second magnetic component 260 may be provided at the charging connection portion 220. When the charging connection portion 220 and the charging receiving slot 120 are fixed relative to each other, the first magnetic component 180 and the second magnetic component 260 can attract each other to enhance the fixing effect between the charging connection portion 220 and the charging receiving slot 120.

[0082] As an optional implementation scheme, refer to Figure 7 and Figure 8 The first magnetic attraction assembly 180 may include a plurality of first magnetic attraction portions 181, which are circumferentially spaced around the charging receiving slot 120. Correspondingly, the second magnetic attraction assembly 260 may include second magnetic attraction portions 261 corresponding one-to-one with the plurality of first magnetic attraction portions 181. When the charging connection portion 220 is installed in the charging receiving slot 120, each second magnetic attraction portion 261 is directly opposite to a first magnetic attraction portion 181, and the polarity between each second magnetic attraction portion 261 and the directly opposite first magnetic attraction portion 181 is opposite, so that the first magnetic attraction portions 181 and the second magnetic attraction portions 261 can attract each other, thereby enhancing the fixing effect between the charging connection portion 220 and the charging receiving slot 120.

[0083] Understandably, in this embodiment, the number of first magnetic attracting parts 181 is the same as the number of second magnetic attracting parts 261. Based on this, the arrangement of the first magnetic attracting parts 181 can be designed so that, regardless of whether the protrusion 250 is located between two adjacent limiting tongues 131 or at the bottom of the limiting tongues 131, each second magnetic attracting part 261 can be aligned and attracted with the first magnetic attracting parts 181.

[0084] As another alternative implementation, the first magnetic absorbing assembly may include a plurality of first magnetic absorbing portions 181, which are spaced apart around a rotation axis. The second magnetic absorbing assembly may include at least one second magnetic absorbing portion 261, the number of which is less than the number of first magnetic absorbing portions 181. When the protrusion 250 is located between two adjacent limiting tongues 131, each second magnetic absorbing portion 261 is directly opposite a portion of the first magnetic absorbing portions 181 and attracts each other to facilitate quick positioning between the charging connection portion 220 and the charging receiving groove 120. When the protrusion 250 rotates to the bottom of the limiting tongue 131, each second magnetic absorbing portion 261 is directly opposite another portion of the first magnetic absorbing portions 181 and attracts each other to enhance the fixing effect between the charging connection portion 220 and the charging receiving groove 120.

[0085] Please refer to the above. Figure 7 and Figure 9 In some embodiments, the charging base 100 may further include a cover plate 190, which is detachably connected to the charging receiving slot 120 so that the cover plate 190 can close the opening of the charging receiving slot 120. When the charging base 100 is provided with two charging receiving slots 120 and only one battery 200 is installed, the opening of the other unused charging receiving slot 120 can be closed with the cover plate 190 to prevent damage to the connection terminals inside the charging receiving slot 120.

[0086] When the charging base 100 is not assembled with the battery 200, the openings of the charging receiving slots 120 on both sides can be covered by the cover plate 190 to protect the charging base 100 from damage.

[0087] The charging base and battery module in this embodiment of the invention allow for the separation of the battery 200 from the electronic device, while the battery 200 is assembled with the charging base 100. When the battery 200 needs to be charged, the charging base 100 can be connected to a power source to charge the battery 200. When the electronic device needs to be used, a connecting cable can be used to connect the charging base 100 to the electronic device, thereby connecting the battery 200 to the electronic device and enabling the battery 200 to supply power to the electronic device.

[0088] When it is necessary to install the battery 200 onto the charging base 100, the charging connector 220 can be placed into the charging receiving groove 120. At this time, the anti-rotation shaft 132 is compressed, and the protrusion 250 is located between two adjacent limiting tongues 131. After rotating the charging connector 220, the protrusion 250 is located at the bottom of the limiting tongue 131, the anti-rotation shaft 132 is aligned with the limiting hole 230 and extends into the limiting hole 230. The limiting tongue 131 and the anti-rotation shaft 132 cooperate to fix the battery 200 onto the charging base 100.

[0089] When it is necessary to remove the battery 200 from the charging base 100, the drive module 170 can be used to drive the elastic element to extend and retract, causing the anti-rotation shaft 132 to disengage from the limiting hole 230. Then, by rotating the charging connection part 220, the battery 200 can be removed. In this way, the charging base 100 in this embodiment can quickly and efficiently remove and install the battery 200.

[0090] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this utility model without departing from the spirit and scope of this utility model. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
