[0034] Figures 1 to 14A battery charging device of a first embodiment is shown. The battery charging device of the first embodiment includes a charging assembly 3.

[0035] The charging assembly 3 includes a housing 31, a charging carrier 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 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.

[0036] The housing 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 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.

[0037] The charging carrier 32 has a charging cavity 321 provided with a 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 a rotating power if there is no need to pour out the battery 8.

[0038] 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.

[0039] 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 placed in the battery inlet 311 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 with the conductive member 33.

[0040] After the battery 8 is fully charged (the detection of the voltage and / or the amount of charge 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, since the battery outlet 312 is located below the battery inlet 311, the battery 8 enters the charging cavity 321 through the battery inlet 311 by its own weight, and is discharged through the battery outlet 312 by separating from the charging cavity 321.

[0041] 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 at a specific position of the battery inlet 311 or the arrangement inlet 11 described below, and can charge the battery 8 more conveniently.

[0042] As one of the specific embodiments, the conductive member 33 is rotationally fixed relative to the shell 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 relative to the shell 31 around itself, but can still move linearly or fixedly relative to the shell 31 along the conductive member 33. The wire (not shown in the figure) electrically connected to the conductive member 33 (the electrical connection 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 the stable rotation of the charging carrier 32, which can improve the reliability.

[0043] As one of the specific embodiments, a power motor 324 is further included, the rotating output end of the power motor 324 is fixedly provided with a power gear 323, the charging carrier 32 is provided with a rotating gear 322 engaged with the power gear 323, and there is an overlapping part between the charging carrier 32 and the power motor 324 when viewed from above. The rotation of the power motor 324 drives the rotating gear 322 through the power gear 323 to make the charging carrier 32 have rotating power, which is beneficial to reduce the width (such as the left-right direction shown in the figure) of the charging assembly 3 and can realize miniaturization. Figure 13

[0044] ​As one of the specific embodiments, the charging assembly 3 further comprises a positioning sensor 34 fixed on the shell 31, the positioning sensor 34 being directly or indirectly connected with the power motor 324; the charging carrier 32 is provided with a rotary positioning disc 341 capable of triggering the positioning sensor 34. The positioning sensor 34 is a sensor for detecting the rotation angle of the positioning sensor 34, for example, the positioning sensor 34 is an infrared sensor, and the rotary positioning disc 341 is a grating disc, both of which cooperate with each other to directly or indirectly feed back the electrical signal of the positioning sensor 34 to the power motor 324, so as to realize the control of the rotation angle of the charging carrier 32, thereby realizing the automatic control of the opening of the charging cavity 321 exposed from the rotation side of the charging carrier 32. Of course, the positioning sensor 34 is not limited to an infrared sensor.

[0045] As one of the specific embodiments, the rotary positioning disc 341 is provided with a rotary positioning opening 342; the positioning sensor 34 comprises a plurality of micro switches 7 uniformly distributed around the rotation axis of the charging carrier 32, the rotary positioning opening 342 is capable of directly facing one of the plurality of micro switches 7 of the positioning sensor 34, and the rotary positioning disc 341 is in abutment with the other micro switches 7 of the positioning sensor 34. The rotary positioning disc 341 triggers the positioning sensor 34 by physical contact with the micro switch 7, which has high reliability and low cost.

[0046] 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 power along the rotation axis of the charging carrier 32 (that is, power along the movable conductive body 331). The horizontal moving force member 36 makes the movable conductive body 331 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 and will not be 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 and ensures the charging reliability.

[0047] As one specific implementation, the conductive component 33 also includes a fixed conductor 339 fixed to the other end of the charging carrier component 32 (i.e., the end opposite to the end where the movable conductor 331 is located). It is easy to understand that both the fixed conductor 339 and the movable conductor 331 are connected to the power output device via wires. For a battery 8, such as an AA battery or a size 5 battery, where the positive and negative terminals are located at opposite ends, the fixed conductor 339 and the movable conductor 331 are respectively positioned against the positive and negative terminals of the battery 8 to achieve charging. It should be noted that the technical solution of adjusting the polarity of the fixed conductor 339 and the movable conductor 331 according to the position of the positive and negative terminals of the battery 8 to correspond to the positive and negative terminals of the battery 8 is existing technology (such as a shared power bank circuit and a shared power bank device capable of reversible insertion disclosed in CN110086221A). 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 resisted by the battery 8, thereby improving the charging reliability.

[0048] like Figure 10 As shown, in one specific embodiment, the charging assembly 3 also includes a power cam 361 with rotational power. The power cam 361 includes a proximal abutment portion 362 and a distal abutment portion 363. It is easy to understand that the distance from the proximal abutment portion 362 to the rotation axis of the power cam 361 is less than the distance from the distal abutment portion 363 to the rotation axis of the power cam 361. The lateral movement force member 36 is fixedly connected to the movable conductor 331. The distal abutment portion 363 is drivenly connected to the movable conductor 331 and / or the lateral movement force member 36. This allows multiple movable conductors 331 to move reliably, and only one cam motor 369 (described later) is needed to drive the power cam 361, resulting in lower cost.

[0049] As one specific implementation, the movable conductor 331 and / or the lateral moving force member 36 tend to move closer to the charging cavity 321, and the distal holding portion 363 can hold the lateral moving force member 36, causing the lateral moving force member 36 to move away from the charging cavity 321. When the power cam 361 rotates, the distal holding portion 363 holds the lateral moving force member 36, causing the lateral moving force member 36 to move away from the charging cavity 321; when the power cam 361 rotates and the distal holding portion 363 does not hold the lateral moving force member 36, the movable conductor 331 and the lateral moving force member 36 move closer to the charging cavity 321 and reset, thus realizing the clamping of the battery 8 by the movable conductor 331. There are multiple movable conductors 331, for example, such as... Figure 10As shown in the diagram, when viewed from above, the power cam 361 is located in the exact center of the four movable conductors 331 (the four movable conductors 331 are separated by the power cam 361 in pairs) to ensure that the lateral movement force member 36 and the four movable conductors 331 are subjected to uniform force. In summary, this design enables the multiple movable conductors 331 to move reliably and at a low cost, while ensuring that the movable conductors 331 reliably contact the battery 8 for charging.

[0050] As one specific implementation (not shown in the accompanying drawings), one of the far-abutting part 363 and the lateral moving force member 36 is provided with an upwardly or downwardly protruding abutting part power column (e.g., cylindrical), and the other is provided with a power column hole or power groove (e.g., a power groove is an elongated hole parallel to the movable conductive body 331). The abutting part power column is embedded in or inserted into the power column hole or the power groove. The lateral moving force member 36 can be reciprocated bidirectionally driven by the far-abutting part 363.

[0051] As one specific implementation, the lateral movement member 36 is provided with a lateral movement member protrusion 368. During the rotation of the power cam 361, the lateral movement member protrusion 368 remains in contact with the power cam 361. It is easy to understand that during the rotation of the power cam 361, the lateral movement member protrusion 368 remains in contact with the power cam 361 under the influence of the movable conductor 331 and / or the lateral movement member 36 tending to approach the charging cavity 321. This prevents the lateral movement member 36 from bouncing and affecting the contact between the movable conductor 331 and the battery 8, ensuring reliable contact between the movable conductor 331 and the battery 8, while reducing the base area of ​​the lateral movement member 36 and the power cam 361, thus improving the reliability of the rotation of the power cam 361.

[0052] As one specific implementation, the charging assembly 3 also includes a cam motor 369 and a position sensor 37 directly or indirectly electrically connected to the cam motor 369. The rotational output end of the cam motor 369 is fixedly connected to the power cam 361, giving the power cam 361 rotational power. The position sensor 37 includes two microswitches 7. The power cam 361 is provided with a retaining groove 364, resulting in a height difference between the near retaining part 362 and the far retaining part 363 along the rotation axis of the power cam 361. One of the near retaining part 362 and the far retaining part 363 abuts against one of the two microswitches 7 of the position sensor 37. Typically, the position sensor 37 is located above the power cam 361. The position sensor 37 feeds back electrical signals directly or indirectly to the cam motor 369 to control the rotation angle of the power cam 361. The power cam 361 triggers the position sensor 37 through physical contact with the microswitches 7, which can reliably control the rotation angle of the power cam 361 at a low cost. The position sensor 37 is electrically connected directly or indirectly to the conductive element 33 to control the energization state of the conductive element 33. For example, when the lateral moving force member 36 and the movable conductor 331 move away from the charging cavity 321, the position sensor 37 controls the conductive element 33 to be de-energized; while when the lateral moving force member 36 and the movable conductor 331 move closer to the charging cavity 321 and the movable conductor 331 presses against the battery 8, the position sensor 37 controls the conductive element 33 to be energized; thereby further improving the charging reliability and safety.

[0053] As one specific implementation, a transition slope 365 is provided between the near-holding part 362 and the far-holding part 363. When the lever 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 jumping and adversely affecting its lifespan and / or the electrical signal it emits.

[0054] As one specific implementation, the charging assembly 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 lateral movement force member 36, and the other end is connected to the charging carrier member 32 and / or the housing 31, so that the movable conductor 331 and / or the lateral movement force member 36 tend to approach the charging cavity 321.

[0055] As one specific implementation, 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, with both ends of the clamping elastic member 35 abutting against the conductive flange 332 of the movable conductor 331 and one end of the charging carrier member 32, respectively, so that the movable conductor 331 tends to approach the charging cavity 321. This implementation is beneficial for reducing the width of the charging component 3 (e.g., Figure 13Miniaturization 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.

[0056] As one of the specific implementation methods, such as Figure 12 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 13 (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.

[0057] 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 11(The dimensions shown are in the left and right directions), so the battery 8 will maintain its position within the tidying cavity 12. After the first battery 8 enters the tidying cavity inlet 121 from the tidying inlet 11, it falls and abuts against a trigger 132, causing the shield 131 to rotate toward the trigger 132. At the same time, the first battery 8 is discharged from one of the tidying cavity outlets 122 (corresponding to the odd-numbered battery 8). When the second battery 8 enters the tidying cavity inlet 121 from the tidying inlet 11, it falls and abuts against another trigger 132, causing the shield 131 to rotate toward the other trigger 132. At the same time, the second battery 8 is discharged from another of the tidying cavity outlets 122 (corresponding to the even-numbered battery 8). And so on, so that multiple batteries 8 can be discharged sequentially from different tidying cavity outlets 122, allowing the batteries 8 to enter the corresponding charging carrier 32. There will be no situation where one charging carrier 32 has no battery 8 but another charging carrier 32 has multiple batteries 8, that is, it can be ensured that the batteries 8 and the charging carrier 32 correspond sequentially. It is easy to understand that the sorting cavity 12 can be multi-layered. The sorting cavity outlet 122 of the upper sorting cavity 12 is connected to the sorting cavity inlet 121 of the lower sorting cavity 12 in sequence, so that the number of sorting cavity outlets 122 is two to the power of N (N is the number of layers). The battery inlet 311 and the charging carrier 32 are also two to the power of N.

[0058] As one specific implementation, the sorting component 1 is provided with an inclined sorting guide plate 111; the bottom end of the sorting guide plate 111 extends to the sorting inlet 11. For cylindrical batteries 8 (such as AAA batteries), the batteries 8 are laid on the sorting guide plate 111, and the batteries 8 roll and fall into the sorting inlet 11 by their own weight, which makes it convenient to input the batteries 8 into the sorting inlet 11.

[0059] As one specific implementation, the tidying component 1 and / or housing 31 are provided with a limiting body 14; the limiting body 14 is located between two trigger bodies 132 of a tidying component 13 and can abut against the two trigger bodies 132 respectively to limit the rotation angle of the blocking body 131. This ensures that the tilt angle of the blocking body 131 is large, so that the battery 8 can be smoothly discharged from the tidying cavity outlet 122.

[0060] like Figure 12As shown, as one specific implementation, it also includes a sorting component 2 with a sorting inlet 21, a large battery slot 22, and a small battery slot 23. The sorting inlet 21 is located below and directly opposite the battery outlet 312 (i.e., when viewed from above, the battery outlet 312 is located inside the sorting inlet 21). The large battery slot 22 is connected to the sorting inlet 21. The inlet end of the small battery slot 23 is located below the large battery slot 22. The large battery slot 22 is provided with a sorting hole 24 that is directly or indirectly connected to the inlet end of the small battery slot 23 (for example, the sorting hole 24 is directly provided on the partition wall between the two and is directly connected). The sorting hole width 241 of the sorting 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 is necessarily less than the large battery slot thickness 221 of the large battery slot 22. After the large batteries 82 (e.g., AA batteries / size 5 batteries) and small batteries 83 (e.g., AAA batteries / size 7 batteries) of battery 8 are discharged from battery outlet 312, they all first enter the large battery slot 22 and move downwards along the large battery slot 22 by their own weight and pass through the sorting hole 24. During this process, the large batteries 82 have a larger diameter and cannot pass through the sorting hole 24, so they can continue to move along the large battery slot 22 to the outlet of the large battery slot 22. The small batteries 83 have a smaller diameter and, due to their own weight, pass through the sorting hole 24 and enter the small battery slot 23, so they can continue to move along the small battery slot 23 to the outlet of the small battery slot 23. This enables the automatic sorting of large batteries 82 and small batteries 83, making them convenient to use. It is easy to understand that "large" and "small" in the terms "large battery slot 22" and "small battery slot 23," "large battery 82" and "small battery 83," and "large battery slot thickness 221" and "small battery slot thickness 231" are relative concepts. Therefore, for AAA batteries / size 7 batteries and AAAA batteries / size 9 batteries, AAA batteries / size 7 batteries are large batteries 82 (but the aforementioned refers to small batteries 83 relative to AA batteries / size 5 batteries), and AAAA batteries / size 9 batteries are small batteries 83. Therefore, the aforementioned structure can be arranged sequentially from top to bottom to achieve the classification of two or more types of batteries 8. A classification guide plate 211 is provided at the classification entrance 21 so that batteries 8 falling from multiple battery outlets 312 move to the entrance end of the large battery slot 22 due to their own weight.

[0061] As one specific implementation, both the large battery compartment 22 and the small battery compartment 23 are horizontally shaped and parallel to each other. This allows the sorting outlet 29 of the small battery compartment 23 to be located above the sorting outlet 29 of the large battery compartment 22.
