[0052] Rechargeable batteries are popular among users because they can be recharged after being depleted for recycling. In related art, rechargeable batteries are usually charged in a charging device. If the rechargeable battery is not removed promptly after being fully charged, it will remain in a charging state, leading to overcharging and shortening the battery life. It can also easily cause the charging device and battery to continue to heat up, which can easily damage them and create safety risks such as fire.

[0053] In order to solve the above problem, the present invention provides a charging device 100 that can enable a fully charged battery to exit the charging state in a timely manner.

Optionally, a charging interface can be provided on the outer wall of the charging box 1 to connect to the charging module 2, or a wireless charging structure such as a wireless receiving coil can be provided in the charging box 1 to connect to the charging module 2. In addition, a control module can be provided in the charging box 1 to control the operating status of other modules in the charging device 100.

[0056] Optionally, in order to facilitate the removal and placement of batteries in the charging space 15, the top of the charging box 1 can be opened or a retractable top cover 13 can be provided. In order to facilitate the removal and placement of batteries in the storage space 16, the side opening of the charging box 1 can be provided, and a side cover can be provided to cover the side opening, or a storage box 12 can be provided to be inserted into the side opening in the following embodiment. At least part of the side wall of the charging box 1 can be provided with a transparent material, for example, the side cover can be provided with a transparent material or a transparent window can be provided on the side cover, and the side wall on the side of the side opening can also be provided with a transparent window. At least part of the structure of the storage box 12 can also be provided with a transparent material in the following embodiment. This arrangement allows the number of rechargeable batteries in the storage space 16 to be observed without opening the storage space 16.

[0057] The charging module 2 includes two charging components 21 arranged opposite to each other, each charging component 21 is respectively provided with an electrode seat 211, and the electrode seat 211 is provided with a conductive electrode 212, and the conductive electrode 212 can be connected to the power supply structure through a structure such as a wire or a flexible circuit board; the electrode seat 211 set on the charging component 21 can be one, two, three or more, and the electrode seats 211 on the two charging components 21 correspond one to one, and the two paired electrode seats 211 are arranged opposite to each other, and a clamping space for clamping the rechargeable battery is formed between the two electrode seats 211, and the conductive electrodes 212 on the two paired electrode seats 211 correspond to the positive pole and the negative pole respectively; the rechargeable battery can be clamped between the two electrode seats 211 so that the two ends of the rechargeable battery are respectively in contact with the two conductive electrodes 212 to form a charging circuit. Among them, one of the charging components 21 can be made movable or both charging components 21 can be made movable; the charging component 21 is driven to move by the driving module 3 so that the electrode seat 211 on the charging component 21 moves closer to or away from the other electrode seat 211 paired with it, so that the two electrode seats 211 are opened or brought closer.

[0058] Optionally, the charging component 21 can be rotatably connected to the charging box 1 so that the charging component 21 can be moved closer to or away from another charging component 21 by rotating the charging component 21; the charging component 21 can also be slidably connected to the charging box 1 so that the charging component 21 can slide in the charging box 1 and move closer to or away from another charging component 21.

[0059] The drive module 3 is used to drive the charging assembly 21. When one of the charging assemblies 21 is movable, only one drive module 3 is provided to drive the movement of the charging assembly 21. Alternatively, when both charging assemblies 21 are movable, two drive modules 3 can be provided in the charging box 1, each connected to the two charging assemblies 21. Alternatively, only one drive module 3 can be provided to simultaneously drive the two charging assemblies 21 to move toward or away from each other.

[0060] Alternatively, the drive module 3 can be configured as a motor 311 or a cylinder, with a drive element directly connected to the charging assembly 21. For example, the drive module 3 can be configured as a motor 311, with the output shaft of the motor 311 connected to the charging assembly 21 to drive the charging assembly 21 to rotate. Alternatively, the drive module 3 can be configured as a cylinder, with the piston rod of the cylinder pulling the charging assembly 21 to slide or swing. In one embodiment, the drive module 3 can also be configured with a transmission structure for connecting the drive element and the charging assembly 21, where the transmission structure can be, but is not limited to, a gear transmission mechanism, a rack and pinion mechanism, a connecting rod transmission mechanism, etc.

[0061] In specific applications, when the battery needs to be charged, the battery clamp is placed between two pairs of electrode holders 211, so that the two ends of the battery are respectively in contact with the conductive electrodes 212 of the two electrode holders 211 to be charged; after the battery is fully charged, the driving module 3 drives the charging component 21 to move, so that the electrode holder 211 is away from the battery, the clamping of the battery is released, and the battery falls into the storage space 16 below and is out of the charging state; thereby avoiding the problem of battery overcharging and continuous heating of the battery and the charging device 100.

[0062] That is, the technical solution of the present invention is to configure the charging module 2 for charging the battery in the charging device 100 as a movable structure, and to drive at least one charging component 21 in the charging module 2 to move through the driving module 3, so that the two electrode holders 211 respectively located in the two charging components 21 and arranged opposite to each other can move away from or approach each other; and to provide a storage space 16 below the charging space 15 in which the charging module 2 is provided. In this arrangement, when the battery needs to be charged, the battery is clamped between the two paired electrode holders 211, so that the two ends of the battery are respectively in contact with the conductive electrodes 212 of the two electrode holders 211 to be charged; after the battery is fully charged, the driving module 3 drives the charging component 21 to move, so that the electrode holders 211 are moved away from the battery, loosening the clamping of the battery, and the battery falls into the storage space 16 below, thereby escaping the charging state; thereby avoiding the problem of battery overcharging and continuous heating of the battery and the charging device 100.

[0063] See also Figure 4 and Figure 5In one embodiment, the charging assembly 21 is rotatably disposed in the charging box 1 so that the electrode holder 211 rotates closer to or away from another corresponding electrode holder 211 .

[0064] In this embodiment, the charging assembly 21 is rotatably disposed within the charging space 15, and the drive module 3 can drive the charging assembly 21 to rotate toward or away from another charging assembly 21. The drive module 3 can be configured as a motor 311, the output shaft of which is connected to the charging assembly 21 to drive the charging assembly 21 to rotate. Alternatively, the drive module 3 can be configured as a cylinder, with the piston rod of the cylinder pushing and pulling the charging assembly 21 to cause the charging assembly 21 to swing. In one embodiment, the drive module 3 can also be configured with a transmission structure for connecting the drive member and the charging assembly 21, wherein the transmission structure can be, but is not limited to, a gear transmission mechanism, a rack and pinion mechanism, a connecting rod transmission mechanism, etc.

[0065] In one embodiment, the charging assembly 21 is slidably disposed on the charging box 1 so that the electrode holder 211 slides along a first direction toward or away from another corresponding electrode holder 211 .

[0066] In this embodiment, the charging component 21 is slidably arranged in the charging space 15, and the driving module 3 can drive the charging component 21 to slide so as to move it closer to or away from another charging component 21; wherein, the driving module 3 can be set as a cylinder, and the charging component 21 is pushed and pulled by the piston rod of the cylinder to make the charging component 21 slide; a motor 311 and a gear rack mechanism, a connecting rod transmission mechanism or a screw transmission mechanism 32 and other matching structures can also be set as the driving module 3, which can also be used to drive the charging component 21 to slide.

The first direction and the second direction are perpendicular to each other, and the driving module 3 is connected to the mounting bracket 213 to drive the mounting bracket 213 to drive the electrode holder 211 to move.

[0068] In this embodiment, the charging assembly 21 includes at least two electrode holders 211, each electrode holder 211 corresponding to an electrode holder 211 on another charging assembly 21, thereby enabling the charging module 2 to charge at least two rechargeable batteries simultaneously. Furthermore, each electrode holder 211 in the charging assembly 21 is mounted on the same mounting bracket 213, and the drive module 3 is coupled to the mounting bracket 213. By driving the mounting bracket 213 in motion, the electrode holders 211 on the charging assembly 21 are driven to move synchronously. This allows each rechargeable battery to be released simultaneously after it is fully charged, eliminating the need for multiple drive modules 3 and simplifying the structure of the charging device 100.

[0069] See also Figure 4 and Figure 5 In one embodiment, the electrode seat 211 is movably disposed on the mounting bracket 213 , and the charging component 21 further includes an elastic member 215 , which is disposed on a side of the electrode seat 211 facing away from the conductive electrode 212 and is clamped between the electrode seat 211 and the mounting bracket 213 .

[0070] In this embodiment, the electrode seat 211 is movable relative to the mounting bracket 213, and an elastic member 215 is arranged between the electrode seat 211 and the mounting bracket 213, and the elastic member 215 is used to apply elastic force to the electrode seat 211; this arrangement can avoid the rechargeable battery being rigidly clamped between the two electrode seats 211, so that the electrode seat 211 can be opened outward for buffering, and the elastic member 215 drives the conductive electrode 212 on the electrode seat 211 to stably contact the rechargeable battery for electrical connection, so that the two paired electrode seats 211 can adapt to charging electrodes of different sizes.

[0071] Optionally, the electrode holder 211 can slide or rotate relative to the mounting bracket 213 , and the elastic member 215 can be configured as a spring or a torsion spring, etc., which is not limited here.

[0072] See also Figure 4 In one embodiment, a mounting groove 2113 is provided on the side of the electrode holder 211 facing away from the conductive electrode 212, and a portion of the elastic member 215 is located in the mounting groove 2113. This arrangement allows the mounting groove 2113 to limit the position of the elastic member 215 and protect the elastic member 215, preventing the elastic member 215 from being directly exposed to the outside and being easily interfered with or damaged by other structures.

[0073] See also Figure 4 In one embodiment, the charging assembly 21 further includes an electrode coupling 214, which is connected to the mounting bracket 213 and is passed through the electrode seat 211. The electrode seat 211 can rotate relative to the mounting bracket 213. The elastic member 215 is a torsion spring, which is sleeved on the electrode coupling 214. The two torsion arms of the torsion spring are respectively in contact with the electrode seat 211 and the mounting bracket 213.

[0074] In this embodiment, the mounting bracket 213 includes a back plate extending in the second direction and two side plates located at either end of the back plate. At least two electrode holders 211 are located on the side of the back plate facing the other charging assembly 21 and are sequentially arranged between the two side plates. An electrode coupling 214 is provided through the two side plates and each electrode holder 211, allowing for rotational connection with the mounting bracket 213 via the electrode coupling 214. The elastic member 215 is configured as a torsion spring sleeved on the electrode coupling 214, with the two torsion arms of the torsion spring respectively abutting against the electrode holder 211 and the back plate. When the rechargeable battery abuts the conductive electrode 212 on the electrode holder 211, the rechargeable battery pushes against the electrode holder 211, causing the electrode holder 211 to rotate toward the back plate, twisting the torsion spring to apply an opposite elastic force to the electrode holder 211, thereby clamping the two paired electrode holders 211 against the rechargeable battery.

[0075] Optionally, a mounting groove 2113 may be provided on the side of the electrode holder 211 facing the back plate, the electrode coupling 214 is passed through the groove walls on both sides of the mounting groove 2113 , and the torsion spring is provided in the mounting groove 2113 .

[0076] See also Figure 2 and Figure 3 In one embodiment, the charging device 100 is provided with two driving modules 3 , and the two driving modules 3 are connected to the two charging components 21 in a one-to-one correspondence to drive the two charging components 21 to move respectively.

[0077] In this embodiment, the charging device 100 is provided with two driving modules 3 for driving the two charging components 21 to move respectively, so that the two charging components 21 can move independently, thereby improving the flexibility of the motion control of the two charging components 21.

[0078] See also Figure 2 and Figure 3 In one embodiment, the drive module 3 is configured as a motor 311, and the output shaft of the motor 311 is connected to the charging assembly 21 to drive the charging assembly 21 to rotate. In this embodiment, the charging assembly 21 is rotatably arranged relative to the charging box 1, and the drive module 3 is configured as the motor 311, so that the output shaft of the motor 311 is directly connected to the charging assembly 21 to drive the charging assembly 21 to rotate. For example, the motor 311 can be directly connected to the electrode holder 211 in the charging assembly 21. When the charging assembly 21 is provided with a mounting bracket 213 and an electrode coupling 214, the output shaft of the motor 311 can also be connected to the mounting bracket 213 or the electrode coupling 214. This configuration eliminates the need for multiple transmission mechanisms 32 in the charging device 100, simplifies the structure of the charging device 100, and reduces torque loss during the transmission process.

[0079] See also Figures 6 to 8In one embodiment, the driving module 3 includes a driving mechanism 31 and two sets of transmission mechanisms 32 , and each charging component 21 is connected to the driving mechanism 31 through a set of transmission mechanisms 32 .

[0080] In this embodiment, the drive module 3 includes a drive mechanism 31 serving as a power source and two transmission mechanisms 32 connected to the drive mechanism 31. The two transmission mechanisms 32 are connected one-to-one with the two charging assemblies 21, enabling the drive mechanism 31 to simultaneously drive the two charging assemblies 21 toward or away from each other. This arrangement allows for synchronized movement of the two charging assemblies 21, ensuring more consistent movement of the paired electrode holders 211 toward or away from each other, thereby effectively clamping and releasing the rechargeable battery.

[0081] In this embodiment, the transmission mechanism 32 can be configured as a gear, a gear set, a rack, a connecting rod transmission structure or a belt transmission structure, etc., which is not limited here.

The drive mechanism 31 drives the two transmission rods 321 in opposite directions, thereby driving the two charging assemblies 21 toward or away from each other. Optionally, the transmission rod 321 can be made to slide only along its length or simultaneously deflect to meet the different movement requirements of the charging assembly 21.

[0084] See also Figure 6 In one embodiment, the driving mechanism 31 includes a motor 311 and a gear 312 connected to the output shaft of the motor 311 , and the transmission rod 321 is configured as a rack, and the two racks are respectively located on the upper and lower sides of the gear 312 and mesh with the gear 312 .

[0085] In this embodiment, the electrode drives the gear 312 to rotate, causing the rack serving as the transmission rod 321 to slide. This arrangement results in a smoother transmission process and higher transmission accuracy, allowing for better control of the movement distance or angle of the charging assembly 21. Furthermore, the two racks are located on either side of the gear 312, without interfering with each other. Furthermore, the drive module 3 is more compact, reducing space usage. Optionally, the two charging assemblies 21 slide relative to each other, moving closer or further away from each other, so that the end of the rack closest to the charging assembly 21 is connected to the charging assembly 21. The reciprocating sliding of the rack drives the charging assembly 21 to slide synchronously. When the charging assembly 21 is rotatably arranged relative to the charging box 1, one end of the rack can be hinged to the charging assembly 21, with the rack hinged eccentrically relative to the center of rotation of the charging assembly 21. Alternatively, a driven gear 312 meshing with the rack can be provided on the charging assembly 21; this is not limited here.

[0086] See also Figure 7 In one embodiment, the driving mechanism 31 includes a motor 311 and a first rotating member 313 connected to the output shaft of the motor 311, and one end of the transmission rod 321 is hinged to the first rotating member 313 and is eccentrically arranged with respect to the rotation center of the first rotating member 313.

[0087] In this embodiment, the first rotating member 313 is roughly in the form of a turntable structure, so that one end of the transmission rod 321 is hinged to the turntable, and the hinge positions of the two transmission rods 321 and the first rotating member 313 are centrally stacked with the rotation center of the first rotating member 313. When the motor 311 drives the first rotating member 313 to rotate, the two transmission rods 321 can be driven to move in opposite directions, thereby driving the two charging components 21 to move toward or away from each other, so as to clamp or release the rechargeable battery.

[0088] See also Figure 8 In one embodiment, the driving mechanism 31 includes a motor 311 and a second rotating member 314 connected to the output shaft of the motor 311. The second rotating member 314 is provided with two connecting columns 3141. The two connecting columns 3141 are eccentrically arranged with respect to the rotation center of the second rotating member 314. The surface of the transmission rod 321 opposite to the rotating member is provided with a connecting groove 3211. The connecting column 3141 is inserted into the connecting groove 3211. When the second rotating member 314 rotates, the connecting column 3141 slides along the connecting groove 3211 to drive the transmission rod 321 to move.

[0089] In this embodiment, the second rotating member 314 is generally in the form of a turntable. The surface of the second rotating member 314 is provided with two connecting posts 3141 arranged symmetrically about its rotational center. The two connecting posts 3141 correspond one-to-one with the two transmission rods 321. Connecting slots 3211 are provided on the surfaces of the transmission rods 321 facing the second rotating member 314. The connecting slots 3211 may or may not extend through both sides of the connecting rods. The connecting posts 3141 are inserted into corresponding connecting slots 3211. When the motor 311 drives the second rotating member 314 to rotate, the connecting posts 3141 push the walls of the connecting slots 3211, driving the connecting rods to move, thereby driving the two charging assemblies 21 to move toward or away from each other, thereby clamping or releasing the rechargeable battery.

[0090] See also Figure 7 In one embodiment, a guide groove 3212 is provided on the side wall of the transmission rod 321, and a guide post 33 is provided in the charging box 1, and the guide post 33 is inserted into the guide groove 3212. This arrangement uses the cooperation between the guide post 33 and the guide groove 3212 to limit and guide the transmission rod 321, preventing the transmission rod 321 from being misaligned and unable to cooperate with the drive mechanism 31 or the charging assembly 21. The transmission rod 321 can slide relative to the guide post 33 along the length of the guide groove 3212, and can also simultaneously cause the transmission rod 321 to yaw with the guide post 33 as the rotation center. For example, when the drive mechanism 31 is configured as a motor 311 and a first rotating member 313 or a second rotating member 314, when the drive mechanism 31 drives the transmission rod 321 to move, the transmission rod 321 needs to yaw.

[0091] See also Figures 6 to 8 In one embodiment, the charging assembly 21 is rotatably connected to the charging box 1, and one end of the transmission rod 321 is hingedly connected to the charging assembly 21 and is eccentrically arranged with respect to the rotation center of the charging assembly 21. This arrangement prevents the transmission rod 321 from interfering with the charging assembly 21 and becoming stuck, ensuring that the driving mechanism 31 can drive the transmission rod 321 to move and thereby drive the charging assembly 21 to rotate.

[0092] See also Figure 1 and Figure 9 In one embodiment, the charging box 1 includes a box body 11 and a storage box 12 . A charging space 15 is provided in the box body 11 . The storage box 12 is inserted below the charging space 15 . The storage box 12 is provided with a storage space 16 .

[0093] This arrangement configures the storage box 12 as a removable drawer. By pulling out the storage box 12, the storage space 16 is exposed, allowing the user to easily remove the rechargeable batteries from the storage space 16 without having to reach under the charging space 15, thereby improving ease of use. Optionally, the entire storage box 12 can be made of a transparent material, or at least a portion of the side wall exposed when the storage box 12 is inserted into the box body 11 can be made of a transparent material. For example, the entire side wall can be made of a transparent material, or a transparent window can be provided on the side wall. This arrangement allows the number of rechargeable batteries in the storage space 16 to be observed without having to pull out the storage box 12.

[0094] Optionally, the storage box 12 is provided with a handle 121, which can be provided as an outwardly convex lug structure, a bar structure, a spherical structure or other structure, or a groove handle, etc. The provision of the handle 121 facilitates the user to pull the storage box 12 and improves ease of use.

[0095] See also Figure 10 In one embodiment, the charging space 15 is provided with a partition structure 14 , which divides the charging space 15 into at least two charging slots 151 , and the two paired electrode holders 211 are respectively located at both ends of the charging slots 151 .

[0096] This arrangement, that is, placing each rechargeable battery in each charging slot 151 and separating them by the partition structure 14, can avoid the risk of short circuit caused by contact between two adjacent rechargeable batteries, thereby improving the safety of the charging process.

[0097] Optionally, the charging space 15 may include two installation areas arranged along the first direction and a charging area located between the two installation areas, and at least two charging slots 151 are provided in the charging area. An avoidance opening may be opened on the end side wall of the charging slot 151 to connect the charging slot 151 and the installation area, so that part of the structure of the electrode seat 211 and the installation bracket 213 are located in the installation area outside the charging slot 151, and the electrode seat 211 and the conductive electrode 212 are exposed in the charging slot 151 through the avoidance opening.

[0098] See also Figure 2In one embodiment, at least one receiving groove 161 is provided at the bottom of the storage space 16, and the groove walls of the receiving groove 161 are close to each other from top to bottom. With this arrangement, when the rechargeable battery falls from the charging space 15 into the storage space 16, it will fall into the limiting groove 2114 along the groove wall of the receiving groove 161, which can prevent the rechargeable battery from moving freely in the storage space 16. In particular, for cylindrical batteries, it can prevent the cylindrical batteries from rolling in the storage space 16. Optionally, each charging component 21 is provided with at least two electrode holders 211, that is, the charging module 2 can charge at least two rechargeable batteries simultaneously. At least two receiving grooves 161 can be provided in the storage space 16, and each receiving groove 161 is located below a pair of electrode holders 211.

[0099] See also Figure 1 and Figure 10 In one embodiment, the top of the charging box 1 is provided with an opening, and a top cover 13 is provided with an openable and closable cover on the opening; with this arrangement, the charging space 15 can be exposed by opening the top cover 13, so that the rechargeable battery can be taken out and placed in the charging space 15; when the rechargeable battery does not need to be taken out and placed, the top cover 13 can be closed to prevent foreign objects from falling into the charging device 100 or damaging the charging module 2 and the rechargeable battery.

[0100] Optionally, the entire top cover 13 can be set as a transparent structure, or a partial area of the top cover 13 can be set as a transparent window, so that the number of rechargeable batteries in the charging space 15 and whether there are idle electrode seats 211 can be observed without opening the top cover 13.

[0101] Optionally, a gripping structure such as a groove or a handle can be provided on the top cover 13 so that the user can take the top cover 13 and open it easily; or an avoidance groove 111 can be provided on the inner edge of the top surface of the box body 11 so that the user can insert a finger or other tool into the avoidance groove 111 to grasp the edge of the top cover 13, thereby facilitating the opening of the top cover 13.

[0102] See also Figure 1 In one embodiment, the charging box 1 is further provided with a display screen 4. The display screen 4 can be used to display the operating status of the charging device 100, the number of rechargeable batteries being charged and the charge level of each rechargeable battery, and the number of batteries in the storage space 16. Optionally, the display screen 4 can be configured as a touch screen to control the operating status of the charging device 100. Of course, control buttons and other structures can also be provided in the charging device 100, which is not limited here.

[0103] See also Figure 11In one embodiment, the electrode holder 211 includes a main body portion 2111 and a limiting portion 2112 connected to each other, the conductive electrode 212 is arranged on the side of the main body portion 2111, the limiting portion 2112 is located below the conductive electrode 212, and the upper surface of the limiting portion 2112 is set to be an inclined surface that gradually tilts downward in a direction away from the main body portion 2111.

[0104] With this arrangement, when the rechargeable battery is clamped between the two electrode holders 211, it is positioned between the two main bodies 2111, with its ends abutting the two conductive electrodes 212. The battery is supported above the two stoppers 2112, improving the battery's positional stability during charging and preventing it from sliding downward. To release the battery, the charging components 21 are moved away from each other, allowing it to gradually slide down along the stoppers 2112, reducing the height of its free fall and minimizing the risk of damage.

[0105] See also Figure 11 In one embodiment, the conductive electrode 212 includes a contact portion 2121 and a connecting portion 2122 respectively connected to both ends of the contact portion 2121. The contact portion 2121 is opposite to and spaced from the electrode holder 211, and one end of the connecting portion 2122 away from the contact portion 2121 is connected to the electrode holder 211.

[0106] In this setting, the conductive electrode 212 is roughly configured as an electrode spring structure, and the abutting portion 2121 of the conductive electrode 212 is used to abut against the rechargeable battery. At this time, the conductive electrode 212 has a certain elastic deformation ability. When the rechargeable battery is clamped between the two electrode holders 211 for charging, the abutting portion 2121 can be abutted by the rechargeable battery and moved toward the side close to the electrode holder 211, avoiding rigid abutment between the abutting portion 2121 and the rechargeable battery, thereby reducing wear between the abutting portion 2121 and the rechargeable battery.

[0107] See also Figure 11 In one embodiment, a limiting groove 2114 is provided on the surface of the electrode holder 211, and part of the conductive electrode 212 is provided in the limiting groove 2114; this setting method can improve the connection strength between the conductive electrode 212 and the electrode holder 211, improve the position stability of the conductive electrode 212, and thus improve the overall structural stability.

This arrangement can also improve the connection strength between the conductive electrode 212 and the electrode holder 211, improve the positional stability of the conductive electrode 212, and thus improve the overall structural stability.
