[0045] Designate the drawings in the specification Figure 5 Attached is the abstract. DETAILED DESCRIPTION

[0046] The specific implementation of the present invention will be described below with reference to the accompanying drawings.

[0047] Figures 1 to 14 The battery charging device of the first embodiment is shown. The battery charging device of the first embodiment includes a charging component 3 .

[0048] The charging assembly 3 includes a housing 31, a charging carrier 32, and a conductive member 33 for electrically connecting to the 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 can usually output a set voltage, such as a +5V voltage, to charge the battery 8 of the lithium battery. As a prior art, the electric output device usually also has a voltage detection and / or charge capacity detection function (such as the rechargeable battery capacity 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.

[0049] The housing 31 is provided with a battery inlet 311 and a battery outlet 312 located below the battery inlet 311. The charging carrier 32 is provided in the housing 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.

[0050] The charging carrier 32 has a rotating power and is provided with a charging cavity 321. The charging cavity 321 is exposed from the rotating side of the charging carrier 32. The rotating side refers to a side that can rotate 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 around the rotating axis of the charging carrier 32. It is easy to understand that if there is no need to dump the battery 8, the charging carrier 32 may not have a rotating power.

[0051] The conductive member 33 extends from the end (ie, one end or both ends) of the charging carrier member 32 into the charging cavity 321 .

[0052] The working principle is that the charging carrier component 32 rotates so that the opening of the charging cavity 321 exposed from the rotating side of the charging carrier component 32 faces the battery inlet 311, and then the battery 8 is placed at 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 component 33, and the battery 8 is charged through the electrical output device electrically connected to the conductive component 33.

[0053] After the battery 8 is charged (the electric output device detects the voltage and / or charging amount of the battery 8 to determine 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 relies on its own weight to enter the charging cavity 321 through the battery inlet 311, and detach from the charging cavity 321 and be discharged through the battery outlet 312.

[0054] It can be seen from the above that the battery charging device of the present invention can charge the battery 8 by simply placing the battery 8 at a specific position of the battery inlet 311 or the tidying inlet 11 described later, which makes it more convenient to charge the battery 8.

[0055] As one of the specific implementations, the conductive member 33 is fixedly rotated relative to the housing 31, and the conductive member 33 is cylindrical and fits the inner wall of the end of the charging carrier 32. In other words, the conductive member 33 cannot rotate around itself relative to the housing 31, but can still move or be fixed along the conductive member 33 relative to the housing 31. The wire electrically connected to the conductive member 33 (not shown in the drawings, the wire is used to electrically connect to the electric output device) will not be wound by itself due to the rotation of the conductive member 33, and the conductive member 33 can also ensure that the charging carrier 32 rotates stably, which can improve reliability.

[0056] As one of the specific implementations, it also includes a power motor 324, a power gear 323 is fixedly provided at the rotation output end of the power motor 324, and the charging carrier 32 is provided with a rotating tooth 322 meshing with the power gear 323. When viewed from above, there is an overlapping portion between the charging carrier 32 and the power motor 324. The power motor 324 rotates, and the rotating tooth 322 is driven by the power gear 323, so that the charging carrier 32 has a rotational power, which is beneficial to reducing the width of the charging component 3 (such as Fig.13 left and right directions as shown) and can be miniaturized.

[0057] As one of the specific implementations, the charging assembly 3 also includes a positioning sensor 34 fixed on the shell 31, and the positioning sensor 34 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 cooperate with each other to directly or indirectly feed back the electrical signal of the positioning sensor 34 to the power motor 324 to control the rotation angle of the charging carrier 32, thereby realizing automatic control of the opening direction of the charging cavity 321 exposed from the rotating side of the charging carrier 32. Of course, the positioning sensor 34 is not limited to an infrared sensor.

[0058] As one of the specific implementations, the rotary positioning disk 341 is provided with a rotary positioning opening 342; the positioning sensor 34 includes a plurality of micro switches 7 evenly distributed around the rotation axis of the charging carrier 32, the rotary positioning opening 342 can face one of the plurality of micro switches 7 of the positioning sensor 34, and the rotary positioning disk 341 abuts against other micro switches 7 of the plurality of micro switches 7 of the positioning sensor 34. The rotary positioning disk 341 triggers the positioning sensor 34 by physically contacting the micro switch 7, which has high reliability and low cost.

[0059] As one of the specific implementations, the conductive member 33 also includes a transverse force member 36 and a movable conductor 331 connected to the transverse force member 36. The transverse force member 36 has power along the rotation axis of the charging carrier member 32 (that is, power along the movable conductor 331). The transverse force member 36 moves the movable conductor 331 away from the charging chamber 321 so that the length of the available charging chamber 321 (the size from the movable conductor 331 to the other end of the charging chamber 321) becomes larger, which can ensure that the battery 8 falls into the charging chamber 321 without getting stuck; then the transverse force member 36 resets the movable conductor 331 and resists the battery 8, which can ensure that the movable conductor 331 resists the battery 8 and ensure charging reliability.

[0060] As one of the specific implementations, the conductive member 33 also includes a fixed conductor 339 fixed to the other end of the charging carrier member 32 (i.e., the other end of one end where the movable conductor 331 is provided). It is easy to understand that the fixed conductor 339 and the movable conductor 331 are both connected to the electric output device through wires. For a battery 8 such as an AA battery / No. 5 battery, whose positive and negative poles are located at both ends, the fixed conductor 339 and the movable conductor 331 are respectively offset against the positive and negative poles of the battery 8 to achieve charging. It should be noted that the technical solution that the electric output device adjusts the positive and negative polarity of the fixed conductor 339 and the movable conductor 331 according to the positive and negative positions of the battery 8 so that they correspond to the positive and negative poles of the battery 8 is a prior art (such as a shared power bank circuit disclosed in CN110086221A and a shared power bank device that can realize positive and reverse insertion, etc.). The fixed conductor 339 and the movable conductor 331 clamp the battery 8 to charge the battery 8, which can ensure that the fixed conductor 339 and the movable conductor 331 are reliably in contact with the battery 8, thereby improving charging reliability.

[0061] like Fig.10 As shown, as one of the specific embodiments, the charging assembly 3 also includes a power cam 361 with rotational power, and the power cam 361 includes a near abutment portion 362 and a far abutment portion 363. It is easy to understand that the distance from the near abutment portion 362 to the rotation axis of the power cam 361 is smaller than the distance from the far abutment portion 363 to the rotation axis of the power cam 361; the lateral force member 36 is fixedly connected to the movable conductor 331; the far abutment portion 363 is drivingly connected to the movable conductor 331 and / or the lateral force member 36. It can make multiple movable conductors 331 move more reliably, and only one cam motor 369 described later is needed to drive the power cam 361, which is low in cost.

[0062] As one of the specific implementations, the movable conductor 331 and / or the transverse force member 36 have a tendency to approach the charging chamber 321, and the far-holding portion 363 can hold the transverse force member 36 to move the transverse force member 36 away from the charging chamber 321. The power cam 361 rotates, and the far-holding portion 363 holds the transverse force member 36 to move the transverse force member 36 away from the charging chamber 321; the power cam 361 rotates, and the far-holding portion 363 does not hold the transverse force member 36, and the movable conductor 331 and the transverse force member 36 are reset close to the charging chamber 321, so that the movable conductor 331 clamps the battery 8. The movable conductor 331 is multiple, for example, Fig.10 When the four movable conductors 331 are shown, the power cam 361 is located in the middle of the four movable conductors 331 when viewed from above (the four movable conductors 331 are separated by two by two by the power cam 361) to ensure that the force of the lateral force member 36 and the four movable conductors 331 is uniform. In summary, the multiple movable conductors 331 can be moved more reliably and at a lower cost, and the movable conductors 331 can be reliably charged by contacting the battery 8.

[0063] As one of the specific implementations (not shown in the drawings), one of the far abutting portion 363 and the lateral force member 36 is provided with an abutting portion power column (e.g., cylindrical) protruding upward or downward, and the other is provided with a power column hole or a power slot (e.g., the power slot is a long hole parallel to the movable conductor 331), and the abutting portion power column is embedded or inserted into the power column hole or the power slot. The far abutting portion 363 can realize reciprocating bidirectional driving of the lateral force member 36.

[0064] As one of the specific implementations, the lateral force member 36 is provided with a lateral force member protrusion 368, and the lateral 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 lateral force member protrusion 368 always keeps in contact with the power cam 361 under the action of the movable conductor 331 and / or the lateral force member 36 having a tendency to approach the charging chamber 321. It can prevent the lateral force member 36 from jumping and affecting the contact between the movable conductor 331 and the battery 8, ensure that the movable conductor 331 and the battery 8 are reliably against each other, and reduce the base area of ​​the lateral force member 36 and the power cam 361 to improve the reliability of the rotation of the power cam 361.

[0065] As one of the specific embodiments, the charging assembly 3 further includes a cam motor 369 and a position sensor 37 directly or indirectly electrically connected to the cam motor 369. The rotation output end of the cam motor 369 is fixedly connected to the power cam 361 so that the power cam 361 has a rotational power. The position sensor 37 includes two micro switches 7. The power cam 361 is provided with a supporting portion groove 364 so that there is a height difference between the near supporting portion 362 and the far supporting portion 363 along the rotation axis of the power cam 361. One of the near supporting portion 362 and the far supporting portion 363 is against one of the two micro switches 7 of the position sensor 37. Usually, the position sensor 37 is located above the power cam 361. The position sensor 37 directly or indirectly feeds back an electrical signal to the cam motor 369 to control the rotation angle of the power cam 361. The power cam 361 triggers the position sensor 37 by physically contacting the micro switch 7, which can reliably control the rotation angle of the power cam 361 and has a low cost. The position sensor 37 is electrically connected to the conductive member 33 directly or indirectly to control the power-on state of the conductive member 33. For example, when the transverse force member 36 and the movable conductor 331 are away from the charging chamber 321, the position sensor 37 controls the conductive member 33 to be powered on; and when the transverse force member 36 and the movable conductor 331 are close to the charging chamber 321 so that the movable conductor 331 is against the battery 8, the position sensor 37 controls the conductive member 33 to be powered on; thereby further improving the charging reliability and safety.

[0066] As one of the specific implementations, a transition slope 365 is provided between the near abutment portion 362 and the far abutment portion 363. When the paddle of the micro switch 7 of the position sensor 37 passes through the transition slope 365, it is buffered by the transition slope 365, which can prevent the micro switch 7 of the position sensor 37 from bouncing and causing adverse effects on the life and / or the electrical signal emitted.

[0067] As one of the specific embodiments, the charging component 3 also includes a clamping elastic member 35; one end of the clamping elastic member 35 is connected to the movable conductor 331 and / or the transverse moving force member 36, and the other end is connected to the charging carrier member 32 and / or the shell 31, so that the movable conductor 331 and / or the transverse moving force member 36 has a tendency to approach the charging cavity 321.

[0068] As one of the specific implementations, a conductive flange 332 is provided at one end of the movable conductor 331; the clamping elastic member 35 is a spring and is sleeved on the movable conductor 331, and the two ends of the clamping elastic member 35 are respectively against the conductive flange 332 of the movable conductor 331 and one end of the charging carrier member 32, so that the movable conductor 331 has a tendency to approach the charging cavity 321. This implementation is conducive to reducing the width of the charging component 3 (such as Fig.13It is easy to understand that the conductive member 33 can be provided with a conductive flange 332, such as the fixed conductor 339 can also be provided with a conductive flange 332 to provide a charging contact area between it and the battery 8.

[0069] As one of the specific implementations, Fig.12 As shown, the housing 31 is further provided with an abnormal outlet 319, which is located below the battery inlet 311 (below the vertical direction) and in the horizontal plane direction ( Fig.13 The battery inlet 311 is located between the battery outlet 312 and the abnormal outlet 319. Usually, the charging assembly 3 is detachably connected to the receiving box 9, and the outlet of the abnormal outlet 319 is connected to the inner cavity of the receiving box 9 to receive the abnormal battery 8 discharged from the abnormal outlet 319. If the electric output device directly or indirectly electrically connected to the conductive member 33 detects an abnormality in the battery 8, for example, the voltage of the battery 8 does not change after charging the battery 8 for a period of time, or the battery 8 has no voltage, etc., the charging carrier member 32 rotates so that the opening of the charging cavity 321 exposed from the rotating side of the charging carrier member 32 faces the abnormal outlet 319 and is away from the battery outlet 312, so that the battery 8 enters the receiving box 9 through the abnormal outlet 319; however, if the electric output device directly or indirectly electrically connected to the conductive member 33 does not detect an abnormality in the battery 8, for example, when the charging of the battery 8 is completed normally according to the procedure, the charging carrier member 32 rotates so that the opening of the charging cavity 321 exposed from the rotating side of the charging carrier member 32 faces the battery outlet 312 and is away from the abnormal outlet 319, so that the battery 8 is discharged through the battery outlet 312, thereby enabling the abnormal battery 8 and the normal battery 8 to be distinguished and processed.

[0070] As one of the specific embodiments, it also includes a sorting component 1, which is provided with a sorting entrance 11 and a sorting cavity 12 connected to the sorting entrance 11 and located below the sorting entrance 11. In the horizontal direction, the sorting entrance 11 only allows a single battery 8 to pass through. A sorting piece 13 is hinged in the sorting cavity 12, and the sorting piece 13 includes a shielding body 131. Both sides of the bottom end of the shielding body 131 are provided with trigger bodies 132; the bottom end of the sorting cavity 12 is respectively provided with sorting cavity outlets 122 corresponding to the two trigger bodies 132, and the battery entrance 311 and the charging carrier 32 are both multiple and respectively face the sorting cavity outlets 122. It is easy to understand that the thickness of the sorting cavity 12 and the thickness of the sorting entrance 11 are roughly equal to the length of the battery 8 ( Fig.11The left-right dimension shown in the figure) is used as the size of the battery 8, so the battery 8 will maintain its posture in the sorting chamber 12. After the first battery 8 enters the sorting chamber entrance 121 from the sorting entrance 11, it falls and abuts against a trigger body 132, so that the shielding body 131 rotates toward the trigger body 132, and the first battery 8 is discharged from one sorting chamber outlet 122 (corresponding to the odd-numbered battery 8) of the sorting chamber 12; when the second battery 8 enters the sorting chamber entrance 121 from the sorting entrance 11, it falls and abuts against another trigger body 132, so that the shielding body 131 rotates toward the other trigger body 132, and the second battery 8 is discharged from another sorting chamber outlet 122 (corresponding to the even-numbered battery 8) of the sorting chamber 12; and so on, multiple batteries 8 can be discharged from different sorting chamber outlets 122 in sequence, so that the batteries 8 enter the corresponding charging carrier 32, and there will be no situation where a certain charging carrier 32 has no battery 8 but another charging carrier 32 has multiple batteries 8, that is, it can ensure that the batteries 8 correspond to the charging carrier 32 in sequence. It is easy to understand that the sorting chamber 12 can be multi-layered, and the sorting chamber outlet 122 of the upper sorting chamber 12 is connected with the sorting chamber inlet 121 of the lower sorting chamber 12 in sequence, so that the number of the sorting chamber outlets 122 is two to the power of N (N is the number of layers), and the battery inlet 311 and the charging carrier 32 are also correspondingly two to the power of N.

[0071] As one of the specific embodiments, the sorting assembly 1 is provided with an inclined sorting guide plate 111; the bottom end of the sorting guide plate 111 extends to the sorting entrance 11. For cylindrical batteries 8 (such as AAA batteries 8), the batteries 8 are laid on the sorting guide plate 111, and the batteries 8 roll and fall into the sorting entrance 11 under their own weight, so that the batteries 8 can be conveniently input into the sorting entrance 11.

[0072] As one of the specific implementations, the sorting assembly 1 and / or the housing 31 is provided with a limiter 14; the limiter 14 is located between two triggering bodies 132 of a sorting member 13 and can respectively abut against the two triggering bodies 132 to limit the rotation angle of the shielding body 131. It can ensure that the inclination angle of the shielding body 131 is large, so that the battery 8 can be smoothly discharged from the sorting chamber outlet 122.

[0073] like Fig.12As shown, as one of the specific embodiments, it also includes a classification component 2 provided with a classification entrance 21, a large battery slot 22 and a small battery slot 23, the classification entrance 21 is located below the battery outlet 312 and directly opposite the battery outlet 312 (that is, the battery outlet 312 is located in the classification entrance 21 when viewed from above), and the large battery slot 22 is connected to the classification entrance 21; the entrance end of the small battery slot 23 is located below the large battery slot 22, and the large battery slot 22 is provided with a classification hole 24 directly or indirectly connected to the entrance end of the small battery slot 23 (for example, the classification hole 24 is directly provided on the partition wall between the two and directly connected); the classification hole width 241 of the classification hole 24 is greater than or equal to the small battery slot thickness 231 of the small battery slot 23, but less than the large battery slot thickness 221 of the large battery slot 22. It is easy to understand that the small battery slot thickness 231 of the small battery slot 23 must be less than the large battery slot thickness 221 of the large battery slot 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 discharged from the battery outlet 312 respectively, they all enter the large battery slot 22 first, and move downward along the large battery slot 22 and pass through the classification hole 24 by relying on their own weight. In this process, the large battery 82 has a larger diameter and cannot pass through the classification hole 24, so it can continue to move along the large battery slot 22 to the outlet of the large battery slot 22, while the small battery 83 has a smaller diameter. When passing through the classification hole 24, it passes through the classification hole 24 due to its own weight and enters the small battery slot 23, so it can continue to move along the small battery slot 23 to the outlet of the small battery slot 23, thereby realizing automatic classification of the large battery 82 and the small battery 83 for easy use. It is easy to understand that the "big" and "small" in the large battery slot 22 and the small battery slot 23, the large battery 82 and the small battery 83, the large battery slot thickness 221 and the small battery slot thickness 231 are relative concepts. Therefore, for AAA battery / No. 7 battery and AAAA battery / No. 9 battery, AAA battery / No. 7 battery is a large battery 82 (but the aforementioned is a small battery 83 relative to AA battery / No. 5 battery), and AAAA battery / No. 9 battery is a small battery 83. Therefore, the aforementioned structure can be arranged in sequence from top to bottom to achieve the classification of two or more than three types of batteries 8. A classification guide plate 211 is provided at the classification entrance 21 so that the batteries 8 dropped from multiple battery outlets 312 move to the entrance end of the large battery slot 22 due to their own weight.

[0074] As one of the specific implementations, the large battery slot 22 and the small battery slot 23 are both in a horizontal V-shape and parallel to each other, so that the classification outlet 29 of the small battery slot 23 can be located above the classification outlet 29 of the large battery slot 22 .

[0075] As one of the specific implementations, the classification outlet 29 of the large battery slot 22 and / or the classification outlet 29 of the small battery slot 23 is provided with a stopper 291 , which can ensure that the battery 8 will not fall off from the classification component 2 .

[0076] Figures 15 to 20 The battery charging device of the second embodiment is shown. The differences between the battery charging device of the second embodiment and the first embodiment mainly lie in the number of layers of the sorting chamber 12, the addition of battery toggling protrusions 325 and toggling protrusion gaps 326 to the charging carrier 32, the addition of a classification component 25 and a posture adjustment component 26 to the classification component 2, the arrangement of a lateral force component 36 and a power cam 361, and the addition of a lateral movement sensor 38 and a lateral movement trigger component 381 to the charging component 3. The lateral movement trigger component 381 is fixedly connected to the movable conductor 331, and triggers the lateral movement sensor 38 (such as a micro switch 7) as the lateral movement force component 36 moves horizontally, and transmits an electrical signal to the display screen on the outer cover 91, displaying the status of each charging carrier component 32.

[0077] like Fig.18 As shown, the battery charging device of the second embodiment also includes an outer cover 91 and a sorting chamber 12 of the sorting assembly 1, which is a single layer and has only two sorting chamber outlets 122. When the battery 8 is placed into the sorting entrance 11, the battery 8 falls onto the battery entrance 311 from the two sorting chamber outlets 122. When a large number of batteries 8 are piled up at the battery entrance 311, the battery 8 will roll to an adjacent battery entrance 311 due to its own weight. By analogy, one sorting entrance 11 or one sorting chamber outlet 122 can correspond to more than two (such as two, three, etc.) battery entrances 311, which can ensure the reliability of the sorting assembly 1 and the speed of outputting the battery 8. Since the batteries 8 are piled up at the battery entrance 311, it is possible that the batteries 8 enter the charging cavity 321 of the charging carrier component 32 corresponding to the battery entrance 311 at once. Therefore, the charging carrier component 32 is provided with a plurality of battery shifting protrusions 325 facing away from the charging cavity 321, and a shifting protrusion gap 326 is provided between two adjacent battery shifting protrusions 325; for example, the opening of the charging cavity 321 and the three battery shifting protrusions 325 are evenly distributed around the rotation axis of the charging carrier component 32. In other words, the angle between two adjacent openings of the charging cavity 321 and the three battery shifting protrusions 325 is ninety degrees. When the charging carrier 32 rotates, the battery moving protrusion 325 can lift the batteries 8 accumulated at the battery inlet 311, so that the batteries 8 accumulated at the battery inlet 311 can more easily enter the battery inlet 311 adjacent to the battery inlet 311, and the batteries 8 accumulated at the battery inlet 311 can enter each battery inlet 311 by analogy; when the charging carrier 32 is reset to the opening of the charging cavity 321 facing upward, the batteries 8 enter the charging cavity 321 from the opening of the charging cavity 321. It is easy to understand that it is feasible to set only one sorting entrance 11 in the sorting assembly 1 without setting the sorting cavity 12 and the sorting member 13. In other words, the sorting assembly 1 only needs to set the sorting entrance 11, so that the height of the sorting assembly 1 can be reduced to achieve miniaturization.

[0078] like Fig.18As shown, in the battery charging device of the second embodiment, the classification component 2 also includes a classification piece 25 hinged to the carrier of the classification component 2 (hinged through a classification piece hinge shaft 259), the classification piece 25 is provided with a classification lift plate 251 and a reset function part 252 for resetting the classification lift plate 251, the classification lift plate 251 blocks the entrance of the large battery slot 22, the reset function part 252 can be a counterweight block or a spring, etc., so that the classification lift plate 251 has a tendency to block the entrance of the large battery slot 22, that is, a reset tendency; the classification hole 24 is provided on the classification piece 25 and is located behind the classification lift plate 251 (that is, behind the battery 8 moves from front to back due to gravity), and the classification piece 25 and the classification hole 24 are both located in front of the axis of the classification piece 25 hinged to the carrier of the classification component 2 (that is, the axis of the classification piece hinge shaft 259), so that the large battery slot 22 is provided with a classification hole 24 indirectly connected to the entrance end of the small battery slot 23. When a large battery 82 falls from the classification entrance 21 onto the classification lifting plate 251, the large battery 82 cannot pass through the classification hole 24, and at least partially stays on the classification lifting plate 251. The self-weight of the large battery 82 causes the classification member 25 to rotate, causing the classification lifting plate 251 to rotate downward to open the entrance of the large battery slot 22. After the large battery 82 enters the large battery slot 22, 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 cross the classification hole 24, and its bottom is not easily stuck in the classification hole 24, thereby improving the reliability of classification. After a small battery 83 falls from the classification entrance 21 onto the classification lifting plate 251, it 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 component 2 of the battery charging device of the second embodiment can more reliably realize the automatic classification of large batteries 82 and small batteries 83, and is easy to use.

[0079] like Fig.17 , 18 As shown, in the battery charging device of the second embodiment, the classification component 2 also includes a posture adjustment member 26 and a yielding member 263, the posture adjustment member 26 is hinged to the yielding member 263 (the posture adjustment member 26 and the yielding member 263 are hinged via a posture adjustment member hinge shaft 261), the yielding member 263 is hinged to a carrier (not shown in the drawings) of the classification component 2 (the yielding member 263 and the carrier of the classification component 2 are hinged via a yielding member hinge shaft 264) and has a tendency to reset (for example, relying on its own weight or a spring), the posture adjustment member 26 is provided with a posture adjustment member limiter 262 which can abut against the yielding member 263 and limit the rotation of the posture adjustment member 26 relative to the yielding member 263; the posture adjustment member 26 is located in the large battery slot 22 and / or the small battery slot 23. When the battery 8 rolls downward or becomes skewed (i.e., as shown in the figure) due to its own weight in the large battery slot 22 or the small battery slot 23, Fig.18As shown, the battery 8 is not perpendicular to the paper but tilted), one end of the battery 8 is first rotated by the posture adjustment member 26, and the posture adjustment member 26 also rotates accordingly during the process until the posture adjustment member limiter 262 abuts against the position-allowing member 263 and the posture adjustment member 26 stops rotating. At this time, the battery 8 is perpendicular to the paper. Fig.18 The paper surface and the posture of the battery 8 are adjusted, and then the battery 8 abuts the posture adjustment member 26 to rotate the position adjustment member 263, and the posture adjustment member 26 makes way for the battery 8 so that the battery 8 continues to roll downward in the adjusted posture (roughly perpendicular to the paper surface), thereby preventing the battery 8 from tilting and getting stuck in the large battery slot 22 or the small battery slot 23, and ensuring that the posture of the battery 8 output from the classification outlet 29 is stable. It is easy to understand that two mutually mirror-symmetrical posture adjustment members 26 can be hinged on each position adjustment member 263, and the axis of the position adjustment member 26 and the position adjustment member 263 are hinged, and the axis of the position adjustment member 26 and the carrier of the classification component 2 are hinged are perpendicular to each other.

[0080] like Fig.19 , 20 As shown, unlike the vertical setting of the rotation axis centerline of the power cam 361 in the battery charging device of the first embodiment, the rotation axis centerline of the power cam 361 in the battery charging device of the second embodiment is horizontally set. Unlike the battery charging device of the first embodiment, in which the lateral force member protrusion 368 is formed by the lateral force member 36 extending in the horizontal plane, the lateral force member protrusion 368 is formed by the lateral force member 36 extending in the vertical direction. The power cam 361 in the battery charging device of the second embodiment is not provided with the abutment groove 364 and the transition slope 365, so it triggers the position sensor 37 by abutting the micro switch 7 of the position sensor 37 through the side of the far abutment portion 363 of the power cam 361.
