[0044] The drawings designated in the description of the application are: Figures 1 to 14 The drawings designated in the description of the application are: DETAILED DESCRIPTION

[0045] The specific embodiments of the application will be described below with reference to the drawings.

[0046] Figure 13 The battery charging device of the first embodiment is shown. The battery charging device of the first embodiment comprises a charging assembly 3.

[0047] The charging assembly 3 comprises a housing 31, a charging carrier member 32, and a conductive member 33 for electrically connecting with an electric output device. It is easy to understand that the electric output device is a device in the prior art that can charge the battery 8, which is usually capable of outputting a set voltage, such as a +5V voltage, to charge the battery 8 of a lithium battery. As prior art, the electric output device usually also has a voltage detection and / or charge amount detection function (such as the chargeable battery power detection device disclosed in CN102005795B, the charging device for secondary batteries disclosed in CN100395939C, etc.) to obtain the state information of the battery 8 after charging. The conductive member 33 is usually made of metal such as copper and has conductivity.​​​

[0048] The shell 31 is provided with a battery inlet 311 and a battery outlet 312 located below the battery inlet 311, and the charging carrier 32 is arranged in the shell 31 and located between the battery inlet 311 and the battery outlet 312. It is easy to understand that the charging carrier 32 is located below the battery inlet 311 and above the battery outlet 312.

[0049] The charging carrier 32 is provided with a charging cavity 321 rotating power, and the charging cavity 321 is exposed from the rotating side of the charging carrier 32. The rotating side refers to the side that can rotate circumferentially around the rotating axis of the charging carrier 32. It is easy to understand that the opening of the charging cavity 321 exposed from the rotating side of the charging carrier 32 can also rotate circumferentially around the rotating axis of the charging carrier 32. It is easy to understand that the charging carrier 32 can also not have rotating power if there is no need to pour out the battery 8.

[0050] The conductive member 33 extends into the charging cavity 321 from the end (i.e. one end or both ends) of the charging carrier 32.

[0051] The working principle is that the rotation of the charging carrier 32 causes the opening of the charging cavity 321 exposed from the rotating side of the charging carrier 32 to face the battery inlet 311, and then the battery 8 is placed in the battery inlet 311 and enters the charging cavity 321 from the battery inlet 311, so that the end of the battery 8 contacts or abuts against the conductive member 33, and the battery 8 is charged by the electric output device electrically connected to the conductive member 33.

[0052] After the battery 8 is fully charged (the detection of the voltage and / or the charge amount of the battery 8 by the electric output device determines whether the charging is completed), the charging carrier 32 is rotated so that the opening of the charging cavity 321 exposed from the rotating side of the charging carrier 32 faces the battery outlet 312, and the battery 8 is discharged through the battery outlet 312 for use. It is easy to understand that because the battery outlet 312 is located below the battery inlet 311, the battery 8 enters the charging cavity 321 through the battery inlet 311 and is discharged through the battery outlet 312 by its own weight.

[0053] As can be seen from the above, the battery charging device of the present application can charge the battery 8 by simply placing the battery 8 in a specific position of the battery inlet 311 or the arrangement inlet 11 described below, and can charge the battery 8 more conveniently.

[0054] In one specific implementation, the conductive element 33 is rotatably fixed relative to the housing 31. The conductive element 33 is cylindrical and fits against the inner wall of the end of the charging carrier 32. In other words, the conductive element 33 cannot rotate relative to the housing 31 around itself, but it can still move or be fixed in a straight line relative to the housing 31. The wires electrically connected to the conductive element 33 (not shown in the figure, used for electrical connection to the electrical output device) will not coil themselves due to the rotation of the conductive element 33. The conductive element 33 also ensures the stable rotation of the charging carrier 32, thereby improving reliability.

[0055] As one specific implementation, it also includes a power motor 324. A power gear 323 is fixedly mounted on the rotational output end of the power motor 324. The charging carrier component 32 is provided with rotating teeth 322 that mesh with the power gear 323. When viewed from above, the charging carrier component 32 and the power motor 324 overlap. The rotation of the power motor 324, through the power gear 323 driving the rotating teeth 322, enables the charging carrier component 32 to rotate, while also helping to reduce the width of the charging assembly 3 (e.g., ...). Figure 10 Miniaturization can be achieved by (as shown in the left and right directions).

[0056] As one specific implementation, the charging assembly 3 also includes a positioning sensor 34 fixed on the housing 31, which is directly or indirectly connected to the power motor 324. The charging carrier 32 is provided with a rotating positioning disk 341 that can trigger the positioning sensor 34. The positioning sensor 34 is a sensor that detects the rotation angle of the positioning sensor 34. For example, the positioning sensor 34 is an infrared sensor, and the rotating positioning disk 341 is a grating disk. The two work together to directly or indirectly feed back the electrical signal of the positioning sensor 34 to the power motor 324, thereby controlling the rotation angle of the charging carrier 32. This enables automatic control of the orientation of the opening of the charging cavity 321 exposed on the rotating side of the charging carrier 32. Of course, the positioning sensor 34 is not limited to an infrared sensor.

[0057] As one specific implementation, the rotating positioning disk 341 has a rotating positioning port 342; the positioning sensor 34 includes a plurality of microswitches 7 evenly distributed around the rotation axis of the charging carrier 32. The rotating positioning port 342 can be directly aligned with one of the plurality of microswitches 7 of the positioning sensor 34, and the rotating positioning disk 341 abuts against the other microswitches 7 of the positioning sensor 34. The rotating positioning disk 341 triggers the positioning sensor 34 by physically contacting the microswitches 7, which has high reliability and low cost.

[0058] As one of the specific embodiments, the conductive member 33 further comprises a horizontal moving force member 36 and a movable conductive body 331 connected with the horizontal moving force member 36, the horizontal moving force member 36 has a power along the rotation axis of the charging carrier member 32 (that is, a power along the movable conductive body 331). The horizontal moving force member 36 makes the movable conductive body 331 move away from the charging cavity 321, so that the length of the charging cavity 321 (the size of the movable conductive body 331 to the other end of the charging cavity 321 is increased, at this time, it can be ensured that the battery 8 falls into the charging cavity 321 without being stuck; then the horizontal moving force member 36 makes the movable conductive body 331 reset and abuts against the battery 8, which can ensure that the movable conductive body 331 abuts against the battery 8 to ensure the reliability of charging.

[0059] As one of the specific embodiments, the conductive member 33 further comprises a fixed conductive body 339 fixed at the other end of the charging carrier member 32 (that is, the other end of the end provided with the movable conductive body 331). It is easy to understand that the fixed conductive body 339 and the movable conductive body 331 are connected with the electric output device through wires. For AA battery / No.5 battery, which has positive and negative electrodes at both ends, the fixed conductive body 339 and the movable conductive body 331 respectively abut against the positive and negative electrodes of the battery 8 to realize charging. It should be noted that the electric output device adjusts the positive and negative polarities of the fixed conductive body 339 and the movable conductive body 331 according to the positions of the positive and negative electrodes of the battery 8, so that the positive and negative electrodes of the battery 8 correspond to the positive and negative electrodes of the fixed conductive body 339 and the movable conductive body 331. The technical scheme is prior art (for example, CN110086221A discloses a shared power bank circuit and a shared power bank device capable of realizing positive and negative insertion). The fixed conductive body 339 and the movable conductive body 331 clamp the battery 8 to charge the battery 8, which can ensure that the fixed conductive body 339 and the movable conductive body 331 reliably abut against the battery 8 and improve the reliability of charging.

[0060] As shown in Figure 10 As one of the specific embodiments, the charging assembly 3 further comprises a power cam 361 with rotation power, the power cam 361 comprises a near abutting portion 362 and a far abutting portion 363, it is easy to understand that the distance from the near abutting portion 362 to the rotation axis of the power cam 361 is less than the distance from the far abutting portion 363 to the rotation axis of the power cam 361; the horizontal moving force member 36 is fixedly connected with the movable conductive body 331; the far abutting portion 363 is drivingly connected with the movable conductive body 331 and / or the horizontal moving force member 36. This can make the plurality of movable conductive bodies 331 move more reliably, and only one cam motor 369 described later is needed to drive the power cam 361, which has a lower cost.

[0061] As one of the specific embodiments, the movable conductive body 331 and / or the horizontal moving force member 36 has a tendency to approach the charging cavity 321, and the far holding portion 363 can hold the horizontal moving force member 36 to make the horizontal moving force member 36 away from the charging cavity 321. The power cam 361 rotates, and the far holding portion 363 holds the horizontal moving force member 36 to make the horizontal moving force member 36 away from the charging cavity 321; the power cam 361 rotates, and the far holding portion 363 does not hold the horizontal moving force member 36, and the movable conductive body 331 and the horizontal moving force member 36 approach the charging cavity 321 to reset, so as to realize the clamping of the battery 8 by the movable conductive body 331. The movable conductive body 331 is multiple, for example, as shown in the four movable conductive bodies 331, and the power cam 361 is located in the middle of the four movable conductive bodies 331 (the four movable conductive bodies 331 are separated by the power cam 361 two by two) to ensure that the horizontal moving force member 36 and the four movable conductive bodies 331 are uniformly stressed. In summary, the multiple movable conductive bodies 331 can be reliably moved, the cost is relatively low, and the reliable abutment of the movable conductive body 331 and the battery 8 can be ensured. Figure 13 As one of the specific embodiments, the movable conductive body 331 and / or the horizontal moving force member 36 has a tendency to approach the charging cavity 321, and the far holding portion 363 can hold the horizontal moving force member 36 to make the horizontal moving force member 36 away from the charging cavity 321. The power cam 361 rotates, and the far holding portion 363 holds the horizontal moving force member 36 to make the horizontal moving force member 36 away from the charging cavity 321; the power cam 361 rotates, and the far holding portion 363 does not hold the horizontal moving force member 36, and the movable conductive body 331 and the horizontal moving force member 36 approach the charging cavity 321 to reset, so as to realize the clamping of the battery 8 by the movable conductive body 331. The movable conductive body 331 is multiple, for example, as shown in the four movable conductive bodies 331, and the power cam 361 is located in the middle of the four movable conductive bodies 331 (the four movable conductive bodies 331 are separated by the power cam 361 two by two) to ensure that the horizontal moving force member 36 and the four movable conductive bodies 331 are uniformly stressed. In summary, the multiple movable conductive bodies 331 can be reliably moved, the cost is relatively low, and the reliable abutment of the movable conductive body 331 and the battery 8 can be ensured.

[0062] As one of the specific embodiments (which is not shown in the drawings), the far holding portion 363 and one of the horizontal moving force members 36 are provided with an upward or downward protruding holding portion power column (such as a cylindrical column), and the other is provided with a power column hole or a power slot (for example, the power slot is a long hole parallel to the movable conductive body 331, etc.), and the holding portion power column is embedded or inserted into the power column hole or the power slot. The horizontal moving force member 36 can be reciprocatingly bidirectionally driven by the far holding portion 363.

[0063] As one of the specific embodiments, the horizontal moving force member 36 is provided with a horizontal moving force member protrusion 368, and the horizontal moving force member protrusion 368 keeps in contact with the power cam 361 during the rotation of the power cam 361. It is easy to understand that during the rotation of the power cam 361, the horizontal moving force member protrusion 368 always keeps in contact with the power cam 361 under the action that the movable conductive body 331 and / or the horizontal moving force member 36 has a tendency to approach the charging cavity 321. It can prevent the horizontal moving force member 36 from jumping to affect the contact of the movable conductive body 331 and the battery 8, ensure the reliable abutment of the movable conductive body 331 and the battery 8, and reduce the basic area of the horizontal moving force member 36 and the power cam 361 to improve the reliability of the rotation of the power cam 361.

[0064] As one of the specific embodiments, the charging assembly 3 further comprises a cam motor 369 and a position sensor 37 directly or indirectly electrically connected with the cam motor 369, the rotating output end of the cam motor 369 is fixedly connected with the power cam 361 so that the power cam 361 has rotating power; the position sensor 37 comprises two micro switches 7, the power cam 361 is provided with an abutting part slot 364 so that there is a height difference between the near abutting part 362 and the far abutting part 363 along the rotating axis of the power cam 361, one of the near abutting part 362 and the far abutting part 363 abuts against one of the two micro switches 7 of the position sensor 37. Generally, the position sensor 37 is located above the power cam 361. The position sensor 37 directly or indirectly feeds back an electric signal to the cam motor 369 to control the rotating angle of the power cam 361, and the power cam 361 triggers the position sensor 37 by physical contact with the micro switch 7, which can reliably control the rotating angle of the power cam 361 and has a low cost. The position sensor 37 is directly or indirectly electrically connected with the conductive part 33 to control the power-on state of the conductive part 33, for example, when the horizontal moving force part 36 and the movable conductive body 331 move away from the charging cavity 321, the position sensor 37 controls the conductive part 33 to be powered off; and when the horizontal moving force part 36 and the movable conductive body 331 move close to the charging cavity 321 so that the movable conductive body 331 abuts against the battery 8, the position sensor 37 controls the conductive part 33 to be powered on; thereby further improving the charging reliability and safety.

[0065] As one of the specific embodiments, an overhanging slope 365 is arranged between the near abutting part 362 and the far abutting part 363. When the actuator of the micro switch 7 of the position sensor 37 passes through the overhanging slope 365, it is buffered by the overhanging slope 365, which can prevent the micro switch 7 of the position sensor 37 from jumping and adversely affecting the service life and / or the electric signal emitted.

[0066] As one of the specific embodiments, the charging assembly 3 further comprises a clamping elastic part 35; one end of the clamping elastic part 35 is connected with the movable conductive body 331 and / or the horizontal moving force part 36, and the other end is connected with the charging carrier part 32 and / or the shell 31, so that the movable conductive body 331 and / or the horizontal moving force part 36 have a tendency to move close to the charging cavity 321.

[0067] As one of the specific embodiments, one end of the movable conductive body 331 is provided with a conductive flange 332; the clamping elastic part 35 is a spring and is sleeved on the movable conductive body 331, and the two ends of the clamping elastic part 35 respectively abut against the conductive flange 332 of the movable conductive body 331 and one end of the charging carrier part 32, so that the movable conductive body 331 has a tendency to move close to the charging cavity 321. This embodiment is beneficial to reduce the width of the charging assembly 3 (such as the width of the charging assembly 3 in the direction perpendicular to the rotating axis of the power cam 361). Figure 12Miniaturization can be achieved by (as shown in the left and right directions). It is easy to understand that conductive parts 33 can all be provided with conductive flanges 332. For example, the fixed conductor 339 can also be provided with conductive flanges 332 to provide its charging contact area with the battery 8.

[0068] As one of the specific implementation methods, such as Figure 13 As shown, the housing 31 is also provided with an abnormality outlet 319, which is located below the battery inlet 311 (vertically below) and in the horizontal direction ( Figure 11 (As shown in the left-right direction) Battery inlet 311 is located between battery outlet 312 and abnormal outlet 319. Typically, the charging assembly 3 is detachably connected to the receiving box 9, and the outlet of abnormal outlet 319 communicates with the inner cavity of the receiving box 9 to receive abnormal batteries 8 discharged from abnormal outlet 319. If the power output device, which is directly or indirectly connected to the conductive element 33, detects an abnormality in the battery 8, such as when the battery 8 voltage does not change after charging for a period of time or when the battery 8 has no voltage, the charging carrier 32 rotates so that the opening of the charging cavity 321 exposed on the rotating side of the charging carrier 32 faces the abnormal outlet 319 and is opposite to the battery outlet 312, allowing the battery 8 to enter the receiving box 9 through the abnormal outlet 319. However, if the power output device, which is directly or indirectly connected to the conductive element 33, does not detect an abnormality in the battery 8, such as when the battery 8 is charged normally according to the program, the charging carrier 32 rotates so that the opening of the charging cavity 321 exposed on the rotating side of the charging carrier 32 faces the battery outlet 312 and is opposite to the abnormal outlet 319, allowing the battery 8 to be discharged through the battery outlet 312, thereby distinguishing and processing abnormal and normal batteries 8.

[0069] As one specific implementation, it also includes a sorting component 1. The sorting component 1 is provided with a sorting inlet 11 and a sorting cavity 12 communicating with and located below the sorting inlet 11. In the horizontal direction, the sorting inlet 11 only allows a single battery 8 to pass through. A sorting member 13 is hinged inside the sorting cavity 12. The sorting member 13 includes a shield 131, and triggers 132 are provided on both sides of the bottom end of the shield 131. The bottom end of the sorting cavity 12 is provided with sorting cavity outlets 122 corresponding to the two triggers 132. There are multiple battery inlets 311 and charging carriers 32, each facing the sorting cavity outlet 122. It is easy to understand that the thickness of the sorting cavity 12 and the thickness of the sorting inlet 11 are approximately equal to the length of the battery 8. Figure 12The battery 8 can keep its posture in the arranging cavity 12, and the first battery 8 falls against one of the trigger bodies 132 to rotate the shielding body 131 towards the trigger body 132, and the first battery 8 is discharged from one of the arranging cavity outlets 122 of the arranging cavity 12 (corresponding to the odd-numbered battery 8); the second battery 8 falls against another trigger body 132 to rotate the shielding body 131 towards the trigger body 132, and the second battery 8 is discharged from another of the arranging cavity outlets 122 of the arranging cavity 12 (corresponding to the even-numbered battery 8); and the batteries 8 can be sequentially discharged from different arranging cavity outlets 122 to enter the corresponding charging carrier 32, and the batteries 8 can be sequentially matched with the charging carriers 32, and the charging carrier 32 without the battery 8 and the charging carrier 32 with multiple batteries 8 can be avoided. It is easy to understand that the arranging cavity 12 can be multi-layered, the arranging cavity outlet 122 of the upper arranging cavity 12 is sequentially communicated with the arranging cavity inlet 121 of the lower arranging cavity 12, the number of the arranging cavity outlets 122 is 2N (N is the number of layers), and the battery inlet 311 and the charging carrier 32 are also 2N.

[0070] As one of the specific embodiments, the arranging assembly 1 is provided with an inclined arranging guide plate 111, and the bottom end of the arranging guide plate 111 extends to the arranging inlet 11. For the cylindrical battery 8 (such as the AAA battery 8), the battery 8 is laid on the arranging guide plate 111, and the battery 8 rolls and falls into the arranging inlet 11 by its own weight, which can conveniently input the battery 8 into the arranging inlet 11.

[0071] As one of the specific embodiments, the arranging assembly 1 and / or the shell 31 is provided with a limiting body 14, and the limiting body 14 is located between two trigger bodies 132 of one arranging body 13 and can abut against the two trigger bodies 132 to limit the rotation angle of the shielding body 131. The inclination angle of the shielding body 131 can be ensured to be large, so that the battery 8 can be smoothly discharged from the arranging cavity outlet 122.

[0072] As shown in FIG. 1, the arranging assembly 1 is provided with a limiting body 14, and the limiting body 14 is located between two trigger bodies 132 of one arranging body 13 and can abut against the two trigger bodies 132 to limit the rotation angle of the shielding body 131. Figures 15 to 20As shown, as one of the specific embodiments, it further comprises a classification assembly 2 provided with a classification entrance 21, a large battery groove 22 and a small battery groove 23, the classification entrance 21 is located below and directly opposite to the battery outlet 312 (i.e. the battery outlet 312 is located in the classification entrance 21 when viewed from above), the large battery groove 22 is in communication with the classification entrance 21; the entrance end of the small battery groove 23 is located below the large battery groove 22, the large battery groove 22 is provided with a classification hole 24 in direct or indirect communication with the entrance end of the small battery groove 23 (for example, the classification hole 24 is directly provided on the partition wall of the two to directly communicate); the classification hole width 241 of the classification hole 24 is greater than or equal to the small battery groove thickness 231 of the small battery groove 23, but less than the large battery groove thickness 221 of the large battery groove 22, it is easy to understand that the small battery groove thickness 231 of the small battery groove 23 must be less than the large battery groove thickness 221 of the large battery groove 22. After the large battery 82 (such as AA battery / No. 5 battery) and the small battery 83 (such as AAA battery / No. 7 battery) of the battery 8 are respectively discharged from the battery outlet 312, they all enter the large battery groove 22 first, and move downward along the large battery groove 22 and pass through the classification hole 24, in this process, the diameter of the large battery 82 is too large to pass through the classification hole 24 and can continue to move along the large battery groove 22 to the outlet of the large battery groove 22, while the diameter of the small battery 83 is small, and it can pass through the classification hole 24 and enter the small battery groove 23 to continue to move along the small battery groove 23 to the outlet of the small battery groove 23 due to its weight, thereby achieving automatic classification of the large battery 82 and the small battery 83 and facilitating use. It is easy to understand that "large" and "small" in the large battery groove 22 and the small battery groove 23, the large battery 82 and the small battery 83, and the large battery groove thickness 221 and the small battery groove thickness 231 are relative concepts of the two, therefore, for AAA battery / No. 7 battery and AAAA battery / No. 9 battery, the AAA battery / No. 7 battery is the large battery 82 (but the foregoing is the small battery 83 relative to the AA battery / No. 5 battery), and the AAAA battery / No. 9 battery is the small battery 83, therefore, the foregoing structure can be arranged in sequence from top to bottom to realize classification of two and more than three batteries 8. The classification guide plate 211 is arranged at the classification entrance 21 to enable the batteries 8 dropped from the plurality of battery outlets 312 to move to the entrance end of the large battery groove 22 due to gravity.

[0073] As one of the specific embodiments, the large battery groove 22 and the small battery groove 23 are both in the shape of a horizontally placed V and parallel to each other. This can enable the classification outlet 29 of the small battery groove 23 to be located above the classification outlet 29 of the large battery groove 22.

[0074] As one of the specific embodiments, the classification outlet 29 of the large battery groove 22 and / or the classification outlet 29 of the small battery groove 23 is provided with a stop block 291. This can ensure that the battery 8 cannot fall off the classification assembly 2.

[0075] Figure 18 The battery charging device of the second embodiment is shown. The battery charging device of the second embodiment differs from the first embodiment mainly in that the number of layers of the sorting cavity 12, the battery poking protrusion 325 and the poking protrusion gap 326 added to the charging carrier 32, the classification component 25 and the posture adjusting component 26 added to the classification assembly 2, the setting of the horizontal moving force component 36 and the power cam 361, the horizontal moving sensor 38 and the horizontal moving trigger 381 added to the charging assembly 3, etc. The horizontal moving trigger 381 is fixedly connected with the movable conductor 331, triggers the horizontal moving sensor 38 (such as the micro switch 7) when the horizontal moving force component 36 moves horizontally, and transmits the electrical signal to the display screen on the outer cover 91 to display the state of each charging carrier 32.

[0076] As shown in Figure 18 The battery charging device of the second embodiment also includes the outer cover 91 and the sorting cavity 12 of the sorting assembly 1 has only one layer and only has two sorting cavity outlets 122. When the battery 8 is placed into the sorting inlet 11, the battery 8 falls onto the battery inlet 311 from the two sorting cavity outlets 122. When the battery 8 is stacked on the battery inlet 311, the battery 8 will roll to the adjacent battery inlet 311 due to its own weight, and the same applies to the battery 8 stacked on the battery inlet 311. The above can ensure the reliability of the sorting assembly 1 and the speed of outputting the battery 8. Since the battery 8 is stacked on the battery inlet 311, the battery 8 may enter the charging cavity 321 of the charging carrier 32 corresponding to the battery inlet 311. Therefore, the charging carrier 32 is provided with a plurality of battery poking protrusions 325 facing away from the charging cavity 321, and the battery poking protrusion gap 326 between the adjacent two battery poking protrusions 325. For example, the opening of the charging cavity 321, and the three battery poking protrusions 325 are uniformly distributed around the rotation axis of the charging carrier 32. In other words, among the opening of the charging cavity 321 and the three battery poking protrusions 325, the included angle between the adjacent two is ninety degrees. When the charging carrier 32 rotates, the battery poking protrusion 325 can lift the battery 8 stacked on the battery inlet 311, so that the battery 8 stacked on the battery inlet 311 can more easily enter the adjacent battery inlet 311 of the battery inlet 311, and the same applies to the battery 8 stacked on the battery inlet 311. The battery 8 can enter each battery inlet 311. When the charging carrier 32 is reset to the opening of the charging cavity 321 facing upward, the battery 8 enters the charging cavity 321 from the opening of the charging cavity 321. It is easy to understand that the sorting assembly 1 can be feasible by setting only one sorting inlet 11 without setting the sorting cavity 12 and the sorting component 13. In other words, the sorting assembly 1 only needs to be provided with the sorting inlet 11, so that the height of the sorting assembly 1 can be reduced to realize miniaturization.

[0077] As shown in Figure 17As shown, the battery charging device of the second embodiment, the classification assembly 2 further comprises a classification piece 25 hinged with the carrier of the classification assembly 2 (hinged through a classification piece hinge shaft 259), the classification piece 25 is provided with a classification lifting plate 251 and a reset function part 252 for resetting the classification lifting plate 251, the classification lifting plate 251 blocks the entrance of the large battery slot 22, the reset function part 252 can be a counterweight or a spring, etc., so that the classification lifting plate 251 has a tendency to block the entrance of the large battery slot 22, that is, a tendency to reset; the classification hole 24 is arranged on the classification piece 25 and located behind the classification lifting plate 251 (that is, behind the direction in which the battery 8 is moved by gravity from front to back), and both the classification piece 25 and the classification hole 24 are located in front of the axis of the hinge between the classification piece 25 and the carrier of the classification assembly 2 (that is, the axis of the classification piece hinge shaft 259), so that the large battery slot 22 is provided with the classification hole 24 indirectly communicated with the entrance end of the small battery slot 23. When one large battery 82 falls on the classification lifting plate 251 from the classification entrance 21, the large battery 82 cannot pass through the classification hole 24 and is at least partially stayed on the classification lifting plate 251, the weight of the large battery 82 makes the classification piece 25 rotate, so that the classification lifting plate 251 rotates downward to open the entrance of the large battery slot 22, and the large battery 82 enters the large battery slot 22, and then the reset function part 252 resets the classification lifting plate 251 to block the entrance of the large battery slot 22. In this process, the large battery 82 does not pass through the classification hole 24, and the bottom of the large battery 82 is not easy to be stuck in the classification hole 24, thereby improving the reliability of classification. When one small battery 83 falls on the classification lifting plate 251 from the classification entrance 21, the small battery 83 can pass through the classification hole 24 and fall into the entrance of the small battery slot 23. As can be seen from the above, the classification assembly 2 of the battery charging device of the second embodiment can automatically classify the large battery 82 and the small battery 83 more reliably, and is convenient to use.

[0078] As shown in the drawings, Figure 18 , 18 As shown, the battery charging device of the second embodiment, the classification assembly 2 further comprises a posture adjusting piece 26 and a yielding piece 263, the posture adjusting piece 26 is hinged with the yielding piece 263 (the posture adjusting piece 26 is hinged with the yielding piece 263 through a posture adjusting piece hinge shaft 261), the yielding piece 263 is hinged with the carrier of the classification assembly 2 (not labeled in the drawings) and has a tendency to reset (such as relying on the weight or a spring), and the posture adjusting piece 26 is provided with a posture adjusting piece limiting body 262 capable of abutting against the yielding piece 263 to limit the rotation of the posture adjusting piece 26 relative to the yielding piece 263; the posture adjusting piece 26 is located in the large battery slot 22 and / or the small battery slot 23. When the battery 8 is rolled downward and tilted in the large battery slot 22 and / or the small battery slot 23 due to the weight, the posture adjusting piece 26 is rotated to adjust the posture of the battery 8, so that the battery 8 is in a vertical state. Figure 18As shown, when battery 8 is tilted instead of perpendicular to the paper, one end of battery 8 is first rotated by attitude adjustment member 26. During this process, attitude adjustment member 26 also rotates accordingly until attitude adjustment member limit body 262 abuts against relief member 263 and attitude adjustment member 26 stops rotating. At this time, battery 8 is perpendicular to the paper. Figure 19 The paper and battery 8 are positioned correctly. Then, battery 8 abuts against the posture adjuster 26, causing the repositioning member 263 to rotate. The posture adjuster 26 repositions battery 8, allowing battery 8 to continue rolling downwards in its adjusted posture (approximately perpendicular to the paper). This prevents battery 8 from tilting and getting stuck in the large battery slot 22 or small battery slot 23, ensuring a stable posture for battery 8 output from the sorting outlet 29. It is easy to understand that two mirror-symmetrical posture adjusters 26 can be hinged to each repositioning member 263. The axis of hinge between the posture adjuster 26 and the repositioning member 263, and the axis of hinge between the repositioning member 263 and the carrier of the sorting component 2, are perpendicular to each other.

[0079] like ​ , 20 As shown, unlike the first embodiment where the rotation axis of the power cam 361 in the battery charging device is vertically arranged, the second embodiment where the rotation axis of the power cam 361 in the battery charging device is horizontally arranged. Unlike the first embodiment where the lateral movement member protrusion 368 is formed by the lateral movement member 36 extending in a horizontal plane, the second embodiment where the lateral movement member 36 extends vertically. In the second embodiment, the power cam 361 does not have a retaining groove 364 and a transition slope 365; therefore, it triggers the position sensor 37 by abutting the microswitch 7 of the position sensor 37 through the side of the far-abutting part 363 of the power cam 361.
