Description

Technical Field

[0001] The present application relates to the technical field of charging boxes, and in particular to an automatic charging structure of a battery charging box and a battery charging box. Background Art

[0002] Cylindrical batteries are widely used in many fields due to their high capacity, long cycle life, and wide range of operating environments. Currently, cylindrical batteries are divided into two categories based on their energy consumption. One category is traditional dry-cell batteries (such as the common zinc-manganese battery). Although these cylindrical batteries are relatively low-cost, they have more stringent operating conditions and are not suitable for high currents or long-term continuous operation. The other category is cylindrical lithium batteries. These batteries have the advantages of being rechargeable and environmentally friendly, and are therefore widely used in electronic products, lighting fixtures, toys, power tools, portable mobile energy sources, and other fields.

[0003] There are two types of cylindrical lithium batteries: rechargeable and non-rechargeable. Rechargeable cylindrical lithium batteries can be recycled, but they require a charging box. The common models of lithium batteries currently used in homes are AA, AA, and AA, with AA and AA being the most commonly used.

[0004] Existing charging boxes typically have only one or more battery compartments for charging batteries, and these compartments require manual access. When a user needs to charge a battery, they simply place the battery into the compartment and then remove it from the compartment once it's fully charged. As we all know, batteries shouldn't be left charging for extended periods of time, as this poses a safety hazard. Furthermore, users often forget to remove the charged battery, so manually removing the fully charged battery from the compartment poses a safety hazard. Summary of the Invention

[0005] In view of this, the present application provides an automatic charging structure for a battery charging box, which is used to solve the technical problem in the prior art that a fully charged battery needs to be manually separated from the charging compartment, which poses a safety hazard.

[0006] In order to achieve one or part or all of the above-mentioned purposes or other purposes, the present application proposes an automatic charging structure of a battery charging box, including: a charging frame, a circuit board, a battery container and a driving assembly; the battery container is rotatably arranged in the charging frame, and the driving assembly drives the battery container to rotate. The battery container is provided with at least one accommodating groove, and the circuit board is provided with at least two pieces and is located at both ends of the length direction of the accommodating groove. The circuit board is provided with a conductive spring for elastically contacting the positive and negative poles of the battery, and the charging frame is provided with a feed port and a discharge port. During the rotation of the battery container, the accommodating groove can be aligned with the feed port and the discharge port respectively, and the conductive spring is set away from the feed port and the discharge port.

[0007] In one embodiment, two battery containers are provided, and each battery container is configured with one driving assembly; the size of the accommodating slot on each battery container is used to accommodate a battery of a corresponding model.

[0008] In one embodiment, three accommodating grooves are provided on each battery accommodating component at equal arc distances, and two groups of conductive springs are provided on the circuit board, and the two groups correspond to two of the accommodating grooves.

[0009] In one embodiment, a temperature detection component for detecting the temperature of the battery being charged is further provided in the charging frame.

[0010] In one embodiment, a battery classification component for classifying batteries is provided below the battery receiving member in the battery frame.

[0011] In one embodiment, the driving assembly includes a driving motor and a gear set, wherein the gear set includes at least two gears, one of which is fixed to the rotating shaft of the battery receiving component and the other is fixed to the output shaft of the driving motor.

[0012] In one embodiment, a display operation screen is provided on the outer side of the charging frame.

[0013] Another object of the present application is to provide a battery charging box, comprising: a feeding structure, a discharging structure and the automatic charging structure as described above, wherein the automatic charging structure is arranged between the feeding structure and the discharging structure, the feeding structure is used to store batteries to be charged, and the discharging module is used to store fully charged batteries and waste batteries.

[0014] In one embodiment, a bracket is further included, and the discharge structure is detachably mounted on the bracket, and the bracket is detachably mounted on a wall.

[0016] The implementation of the embodiments of the present application has the following beneficial effects:

[0017] In the present application, the battery can be rotated and transported by the rotating battery container. When the battery needs to be charged, the battery container drives the battery to the conductive spring sheet for charging under the drive of the driving component. After the charging is completed, the driving component drives the battery container to rotate to separate the fully charged battery from the conductive spring sheet, effectively avoiding long-term charging and eliminating the need for manual separation by the user, which is convenient for the user and ensures safety.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] It should be understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0040] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0041] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0042] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0043] like Figure 1-Figure 3 As shown, a battery charging box provided in an embodiment of the present application is now described in detail. The battery charging box includes: a feed structure 1, an automatic charging structure 2, and a discharge structure 3, which are stacked one above the other. To facilitate assembly or maintenance of the feed structure 1, the automatic charging structure 2, and the discharge structure 3, the feed structure 1, the automatic charging structure 2, and the discharge structure 3 are all assembled in a detachable manner, such as by plugging, snapping, or screwing, which is not specifically limited here.

[0044] The automatic charging structure 2 is located between the feed structure 1 and the discharge structure 3. It is used to charge the batteries provided by the feed structure 1 and discharge the fully charged batteries and the used batteries into the discharge structure 3 for storage. The feed structure 1 is used to store batteries to be charged. Users can place multiple batteries to be charged. The discharge module is used to store fully charged batteries and used batteries. It has a waste bin 31 and a fully charged bin 32 inside.

[0045] In this embodiment, the battery charging box further includes a bracket 4, to which the discharge structure 3 is detachably mounted, and the bracket 4 is detachably mounted on a wall. This allows the user to install the battery charging box in a convenient location according to their needs. Furthermore, the provision of the bracket 4 effectively prevents the battery charging box from being lost and facilitates storage.

[0046] In this embodiment, the battery charging box is described as being capable of charging two types of batteries. Of course, according to actual needs, the corresponding structure can be expanded to realize charging of more types of batteries, and the detailed structure is not described here.

[0047] like Figure 3-Figure 5 As shown, in this embodiment, two feeding bins 11 for placing batteries of different models are provided in the feeding structure 1, and an arrangement channel 12 is provided in each feeding bin 11. The discharge port of the arrangement channel 12 is connected to the feeding port 25 of the automatic charging structure 2. The function of the arrangement channel 12 is to change the movement trajectory of the battery and to arrange the battery in an orderly manner in the feeding bin 11, so as to facilitate the automatic charging structure 2 to automatically charge the battery one by one. Among them, the arrangement channel 12 is formed by a first guide structure 13. The first guide structure 13 can be designed according to the size of batteries of different models to isolate and distribute batteries of different models. For example, AA batteries and AAA batteries are isolated from each other and evenly arranged in the feeding bin 11.

[0048] In this embodiment, a dust cover 14 is provided on the top of the feed structure 1. This rotatable dust cover 14 allows for opening and closing the entrance to the feed bin 11. The user can open the cover to place batteries and close it afterward. The top surface of the dust cover 14 is labeled, such as AA or AAA, to indicate which battery model the user should place in the corresponding feed bin 11. For example, AA indicates a size 5 battery, and AAA indicates a size 7 battery. The use of AA and AAA batteries is merely illustrative and should not be construed as limiting; other battery models are possible.

[0049] like Figure 4 , Figure 6-9As shown, in this embodiment, the automatic charging structure 2 includes: a charging frame 21, a circuit board 22, a battery container 23, and a drive assembly 24. The battery container 23 is rotatably mounted within the charging frame 21, and the drive assembly 24 drives the battery container 23 to rotate. The battery container 23 is provided with at least one receiving groove 231, which is an arc-shaped groove with an opening to allow the battery to automatically roll into the receiving groove 231. At least two circuit boards 22 are provided, located at both ends of the receiving groove 231 in the longitudinal direction. The circuit boards 22 are provided with conductive springs 221 for elastically contacting the positive and negative poles of the battery. The charging frame 21 is provided with a feed port 25 and a discharge port 26. The feed port 25 is used to connect with the outlet of the arrangement channel 12 of the feed structure 1. During the rotation of the battery accommodating member 23, the accommodating slot 231 can be aligned with the feed port 25 and the discharge port 26 respectively. The conductive spring 221 is arranged offset from the feed port 25 and the discharge port 26 to ensure the stability of the battery position during charging. The outer peripheral surface of the charging frame 21 corresponding to the battery accommodating member 23 is an arc-shaped side surface, which is used to confine the battery within the accommodating slot 231 and limit the rolling of the battery driven by the battery accommodating member 23.

[0050] Since the battery charging box can charge two types of batteries. In this embodiment, two battery accommodating parts 23 are arranged side by side and spaced apart. Each battery accommodating part 23 is equipped with a driving assembly 24. In this way, each battery accommodating part 23 can rotate independently, so that the charging of batteries of different types does not affect each other. The size of the accommodating slot 231 on each battery accommodating part 23 is used to accommodate the corresponding type of battery. Figure 3 The battery container 23 on the left side is used to charge AAA batteries, and the size of the accommodating slot 231 of the battery container 23 is adapted to the size of the AAA battery; Figure 3 The battery container 23 on the middle right side is used to charge AA batteries, and the size of the accommodating groove 231 of the battery container 23 is adapted to the size of AA batteries.

[0051] In this embodiment, the drive assembly 24 includes a drive motor 241 and a gear set 242. The gear set 242 has at least two gears: one fixed to the rotation axis of the battery container 23, and the other fixed to the output shaft of the drive motor 241. The drive motor 241 and the gear set 242 cooperate to achieve rotation of the battery container 23. The gear set 242 is preferably a reduction gear set to better determine the rotational position of the battery container 23. A position sensor can be installed at a position corresponding to the rotational position of the battery container 23, and the position sensor is electrically connected to the circuit board.

[0052] To improve charging efficiency, in this embodiment, the battery accommodating member 23 is a cylindrical frame structure. Each battery accommodating member 23 has three accommodating slots 231 spaced at equal arc distances. Two groups of conductive springs 221 are provided on the circuit board 22, corresponding to each battery accommodating member 23, with the two groups corresponding to the two accommodating slots 231. This allows each battery accommodating member 23 to charge two batteries at a time, significantly improving charging efficiency. Of course, the number of accommodating slots 231 can be increased accordingly based on actual needs and the size of the battery accommodating member 23, and this is not limited here.

[0053] In this embodiment, the circuit board 22 is arranged on the outside of the charging frame 21, and the charging frame 21 is arranged in a shell. Similarly, the feeding structure 1 and the discharging structure 3 both include a frame structure and a shell structure. In this embodiment, four circuit boards 22 are provided, which are respectively arranged on an outer surface of the charging frame 21. If the charging frame 21 is a rectangular frame structure, the two circuit boards 22 in the length direction are used to install the conductive springs 221 and detect whether the battery is a valid battery. If the battery is detected to be a failed battery (that is, a waste battery), it will not be charged; the two circuit boards 22 in the width direction are respectively used to electrically connect the display operation screen 7, the temperature detection component 5 and set a charging interface for connecting to an external power supply, etc.

[0054] To ensure safety during charging, a temperature detection component 5 for detecting the temperature of the battery being charged is further provided in the charging frame 21. In this embodiment, the conductive spring 221 is positioned as the charging position, and the temperature detection component 5 is disposed in the receiving groove 231 corresponding to the charging position.

[0055] like Figure 8 , Figure 10-11 As shown, the temperature detection component 5 includes a metal shrapnel 51 and a temperature sensor 52. The metal shrapnel 51 is fixed on the charging frame 21, and the metal shrapnel 51 is arranged in an arc shape and is used to contact the side of the battery. The temperature sensor 52 is arranged near the position where the metal shrapnel 51 contacts the battery. The temperature sensor 52 is electrically connected to the circuit board 22 in the width direction of the charging frame 21. During the charging process, the metal shrapnel 51 transmits the temperature of the battery during charging to the temperature sensor 52, and the temperature sensor 52 transmits the detected temperature data to the circuit board 22. The circuit board 22 monitors the detected temperature according to a preset program. If the preset temperature is exceeded, charging is stopped to prevent damage caused by excessive temperature, and the user is reminded to pay attention, effectively avoiding fire and ensuring safety. Among them, the reminder method can be set to remind the user in the form of light or voice alarm.

[0056] In order to ensure that the metal spring 51 better contacts the outside of the battery, a bending portion 511 is provided on the metal spring 51. The bending portion 511 protrudes toward the inside of the arc and elastically contacts the side of the battery. The temperature sensor 52 is arranged at the bending portion 511.

[0057] As can be seen from the above, one battery accommodating member 23 can charge two batteries. To this end, the ends of the metal spring 51 can be extended to corresponding charging positions. The bent portion 511 is provided with two charging positions corresponding to the batteries. When the battery accommodating member 23 is rotated to the charging position, the battery pushes the metal spring 51 apart, allowing the bent portion 511 to elastically abut against the side of the battery. When the battery accommodating member 23 is rotated to remove the battery from the charging position, the bent portion 511 automatically returns to its original position due to the elastic force of the metal spring 51, ready for the next battery contact.

[0058] In order to facilitate the battery to better open the metal spring 51, the bending portion 511 is trapezoidal or arc-shaped, so that the bending portion 511 has a guiding inclined surface or a guiding arc surface.

[0059] In this embodiment, to facilitate electrical connection and signal transmission between the temperature sensor 52 and the circuit board 22, the temperature detection assembly 5 also includes a flexible circuit board 53. The temperature sensor 52 is disposed on the flexible circuit board 53 and is electrically connected to the circuit board 22. Specifically, the flexible circuit board 53 conforms to the curved outer side of the metal dome 51. Both ends of the flexible circuit board 53 extend to a bend 511 and also have a bend. Thermally conductive adhesive 54 is also provided at the bend 511 to protect and secure the temperature sensor 52. The thermally conductive adhesive 54 fills the bend 511. To better ensure that the flexible circuit board 53 and the metal dome 51 are in contact, an adhesive overflow port 531 is provided at the bend 511. The adhesive overflow port 531 communicates with the metal dome 51. When the thermally conductive adhesive 54 is dispensed, it adheres to the metal dome 51 through the adhesive overflow port 531, ensuring heat transfer between the metal dome 51 and the temperature sensor 52. Specifically, the end surface of the flexible circuit board 53 is also provided with a glue overflow notch, through which the thermal conductive adhesive 54 adheres to the metal spring 51 and conducts heat. To facilitate electrical connection between the flexible circuit board 53 and the circuit board, the flexible circuit board 53 is provided with an extension connection portion 532, which can be independently bent to facilitate electrical connection with the circuit board.

[0060] Preferably, the temperature sensor 52 is a sheet-shaped NTC temperature sensor 52; and the metal sheet is a copper sheet or a stainless steel sheet.

[0061] like Figure 3 、 Figure 8 and Figure 12As shown, in this embodiment, in order to better classify and collect batteries of different models and waste batteries, a battery classification component 6 for classifying batteries is provided below the battery receiving part 23 in the charging frame 21 .

[0062] The battery sorting assembly 6 is arranged below the discharge of the battery container 23, that is, below the discharge port 26. Specifically, it includes a sorting drive and a sorting frame 61. The sorting frame 61 is slidably arranged in the charging frame 21 and is provided with a sorting slot. The sorting drive is arranged on the charging frame and is in transmission connection with the sorting frame 61. The sorting drive drives the sorting frame 61 to reciprocate so that the sorting slot is connected to the discharge port 26 corresponding to the battery container 23 and the waste inlet 33 and the fully charged inlet 34 corresponding to the discharge structure 3.

[0063] As can be seen from the above description, this embodiment can charge both battery types. However, some batteries may fail, which are considered waste batteries. Therefore, in this embodiment, three sorting slots are arranged side by side: a waste battery sorting slot 62, a first type sorting slot 63, and a second type sorting slot 64. Similarly, the discharge structure 3 includes a waste bin 31, a first type collection bin, and a second type collection bin.

[0064] In this embodiment, the waste bin 31 is located below the battery accommodating member 23 for charging the first type of battery. Specifically, the battery accommodating member 23 on the left is used to charge AAA batteries, and the battery accommodating member 23 on the right is used to charge AAA batteries.

[0065] In a preferred embodiment, the first type classification slot 63 is disposed between the waste battery classification slot 62 and the second type classification slot 64, and the width of the first type classification slot 63 is smaller than the width of the second type classification slot 64. The waste battery classification slot 62 and the second type classification slot 64 have the same size. The first type classification slot 63 allows the passage of batteries of the first type, and the second type classification slot 64 allows the passage of batteries of the second signal. The waste battery classification slot 62 allows the passage of batteries of the first and second types. Taking a specific type as an example, the first type classification slot 63 is used to transport AAA batteries, the second type classification slot 64 is used to transport AAA batteries, and the waste battery classification slot 62 is used to transport expired AAA batteries. A horizontal plane is formed between the waste inlet 33 of the waste bin 31 and the fully charged inlet 34 of the first type collection bin. The fully charged inlet 34 of the first type collection bin and the second type collection bin are separated by a partition. In this embodiment, the battery discharge openings 26 of the two battery containers 23 are both inclined toward the line of symmetry between them.

[0066] In the actual process, the user puts the battery of the corresponding model into the feeding structure 1, and after being guided by the first guide structure 13, it falls into the corresponding receiving groove 231 of the battery receiving part 23. The battery receiving part 23 rotates to drive the battery to the charging position. First, the battery is checked to see if it is a normal battery. If it is a normal battery, charging continues; if it is a failed battery, the battery receiving part 23 continues to rotate. At the same time, the classification drive drives the sorting frame 61 to slide, and the waste battery classification groove 62 is aligned with the battery discharge port 26. Alignment, when the battery automatically falls from the accommodating port to the waste battery classification slot 62 below, if the battery is a No. 7 battery, the battery will automatically fall into the waste bin 31 after being guided by the waste battery classification slot 62; if the battery is a No. 5 battery, the classification drive member drives the sorting frame 61 to move to the left. Under the action of the above-mentioned horizontal plane, the battery will not fall out of the waste battery classification slot 62 until the sorting frame 61 moves to the waste battery classification slot 62 and docks with the waste inlet 33 of the waste bin 31, and the waste battery automatically falls into the waste bin 31.

[0067] Similarly, when a normal battery is fully charged, if the battery is a No. 5 battery, the classification drive drives the sorting frame 61 to slide and dock the second model classification slot 64 with the corresponding battery discharge port 26. At this time, the above-mentioned partition block is located below the second model classification slot 64; after the docking is completed, the battery accommodating part 23 rotates and causes the No. 5 battery to fall into the second model classification slot 64. Since the size of the first model classification slot 63 is smaller than that of the No. 5 battery and the function of the partition block, the No. 5 battery will not be stuck at the fully charged entrance 34 of the first model collection bin. The classification drive drives the sorting frame 61 to slide to the right until the second model classification slot 64 docks with the fully charged entrance 34 of the second model collection bin, and the fully charged No. 5 battery automatically falls into the second model collection bin for temporary storage. Similarly, if the battery is a AAA battery, the sorting drive drives the sorting frame 61 to slide and align the first type sorting slot 63 with the corresponding battery discharge port 26. At this time, the bottom of the first type sorting slot 63 is blocked by the aforementioned horizontal surface. When the AAA battery falls into the first type sorting slot 63 and can roll on the horizontal surface, the sorting drive drives the sorting frame 61 to slide right until the first type sorting slot 63 aligns with the fully charged entrance 34 of the first type collection bin. The AAA battery automatically falls into the first type battery collection bin for collection.

[0068] In this embodiment, the length of the first type classification slot 63 gradually decreases from top to bottom in order to better adapt to the length of the first type of battery. The cross section of the classification slot is rectangular, and each classification slot is formed by the first partition 65.

[0069] In a specific embodiment, the classification drive includes a classification motor 66 and a transmission member connected to the output shaft of the classification motor 66, and the transmission member is connected to the sorting frame 61. The transmission member includes a classification gear 67 and a classification rack 68, the classification gear 67 is set on the output shaft of the classification motor 66, and the classification rack 68 is set on the sorting frame 61; the forward and reverse rotation of the classification motor 66 can realize the left and right reciprocating sliding of the sorting frame 61 through the engagement of the classification gear 67 and the classification rack 68. In this embodiment, the classification rack 68 is set at the top or bottom of the sorting frame 61. The classification drive uses a gear and rack to drive the sorting frame 61 to slide back and forth, which can reduce the space occupied by the classification drive, simplify the installation difficulty and ensure the stability of the reciprocating sliding. Of course, in order to ensure the accuracy of the left and right sliding position of the sorting frame 61, a sensor can be set at the corresponding position on the charging frame 21, and the position is located by the sensor to ensure the smooth docking of the classification slot.

[0070] In order to facilitate the determination of charging information, a display operation screen 7 is provided on the outer side of the charging frame 21 for displaying real-time charging information.

[0071] In this embodiment, if Figure 3 、 Figure 13-15 As shown, a waste bin 31 and a fully charged bin 32 are provided in the discharge structure 3. The fully charged bin 32 is divided into a first type collection bin and a second type collection bin. The top of the waste bin 31 is connected to the battery classification component 6 through a waste inlet 33, and the fully charged bin 32 is connected to the battery classification component 6 through a fully charged inlet 34.

[0072] In this embodiment, a first type collection bin and a second type collection bin are formed in the fully charged bin 32 by setting a second guide structure 35. A fully charged drawer 37 is provided in the fully charged bin 32, and a waste drawer 36 is provided in the waste bin 31. The drawer is used to temporarily store batteries, and the drawer can be pulled out for user convenience.

[0073] In this embodiment, in order to ensure that the battery rolls in the second guide structure 35, the second guide structure 35 is composed of a plurality of spaced-apart partition plates, each of which is stepped. The second guide structure 35 forms a battery rolling channel, and the stepped partition plates can consume the energy of the battery rolling and effectively control the speed of the battery during the rolling process.

[0074] The waste drawer 36 is at the top, positioned above and below the fully charged drawer 37. The fully charged drawer 37 comprises a discharge plate 371 and a discharge base 372, each of which is vertically positioned at one end. The discharge base 372 slides into the fully charged compartment 32. A battery stopper 38 is pivotally mounted at the discharge port of the second guide structure 35. When the fully charged drawer 37 is fully closed, the battery stopper 38 removes its obstruction of the discharge port, allowing fully charged batteries to roll normally into the fully charged drawer 37 after passing through the second guide structure 35. When the drawer is pulled out, the battery stopper 38 blocks the discharge port and restricts the batteries from rolling out, preventing newly charged batteries from falling into the fully charged compartment 32. After the user removes the fully charged batteries, they reclose the fully charged drawer 37 and reopen the battery stopper 38, allowing the fully charged batteries to automatically roll into the drawer.

[0075] In this embodiment, the battery blocking member 38 includes a movable baffle 381 and an inclined protrusion 382. There is an angle between the movable baffle 381 and the inclined protrusion 382, and the angle is 45°-60°. The inclined protrusion 382 is located in the middle of the movable baffle 381. The two ends of the movable baffle 381 are rotatably set by the rotating shaft 383. A limiting portion 373 is provided on the discharging bottom plate 372. A bevel groove 374 is provided at the limiting portion 373 for inserting the bevel protrusion 382. The bevel groove 374 is a guide groove. When the bevel protrusion 382 is inserted into the bevel groove 374, it will synchronously drive the movable baffle 381 to rotate. Therefore, when the inclined protrusion 382 is plugged into the inclined groove 374, the fully charged drawer 37 is in a closed state, the movable baffle 381 rotates downward, the movable baffle 381 cancels the obstruction to the battery, and the battery can roll normally into the fully charged drawer 37; when the fully charged drawer 37 is pulled out, the inclined protrusion 382 is separated from the inclined groove 374. During the separation process, the movable baffle 381 gradually rotates upward to block the battery and prevent the new fully charged battery from falling.

[0076] In this embodiment, the sides of the discharge base plate 372 are hooked or snapped onto the inner wall of the discharge frame. For example, slots are provided on either side of the discharge base plate 372, and corresponding chutes are provided on the discharge frame for sliding engagement with the discharge base plate 372. Curved protrusions protrude from the chutes, and these protrusions snap into engagement with the slots, providing a certain degree of damping when the fully charged drawer 37 is withdrawn. Alternatively, bumps are provided on either side of the discharge base plate 372, and corresponding hooks are provided on the discharge base plate 372, with the bumps snapping into engagement with the hooks. The bumps can be made of a deformable material, such as rubber, to provide a certain degree of damping when the fully charged drawer 37 is withdrawn. Furthermore, a snap block is provided on the inner end surface of the waste drawer 36 corresponding to the waste bin 31, and an elastic snap is provided within the discharge frame, snapping into engagement with the snap block. This also provides a certain degree of damping when the waste drawer 36 is withdrawn. The drawer has a certain damping force when it is pulled out, which can ensure the stability of the drawer closing. At the same time, it gives the user a clear feeling during the opening or closing process to remind the customer when it is opened or closed in place.

Specifically, the support member 41 is an L-shaped bracket 4, comprising a support plate 411 and a vertical plate 412. The vertical plate 412 is detachably mounted on the fixed surface, which can be a wall or other flat surface.

[0078] In this embodiment, four second mounting holes 4121 are provided on the vertical plate 412, and the vertical plate 412 is removably mounted to the fixing surface via second fasteners. To ensure the load-bearing capacity of the support member 41, the support member 41 is a metal member, preferably made of stainless steel. The surface of the support member 41 can be painted in different colors according to the desired appearance.

[0079] In this embodiment, the detachable connector 42 is engaged with the bottom of the discharge structure 3, thereby achieving detachable assembly and ensuring the stability of the battery charging box placed on the supporting plate 411 to a certain extent.

[0080] Specifically, the detachable connector 42 includes a first connector 421, a spring 422, and a second connector 423. The first connector 421 and the second connector 423 are slidably assembled, and the two ends of the spring 422 respectively abut on the first connector 421 and the second connector 423 and drive the first connector 421 and the second connector 423 away from each other. The end of the first connector 421 away from the second connector 423 is provided with a first hook 4211, and the end of the second connector 423 away from the first connector 421 is provided with a second hook 4231. The hook portions of the first hook 4211 and the second hook 4231 face opposite directions. The bottom of the discharge structure 3 is provided with a first slot 39 and a second slot 310 that are respectively engaged with the first hook 4211 and the second hook 4231. When assembly is required, press the first connecting member 421 so that the first connecting member 421 and the second connecting member 423 move closer to each other, and the spring 422 is in a compressed state; then align the first hook 4211 and the second hook 4231 with the first slot 39 and the second slot 310 respectively and insert them, release the pressing force, and the spring 422 automatically pops the first connecting member 421 open, so that the first hook 4211 and the second hook 4231 are engaged with the bottom of the discharge structure 3.

[0081] Specifically, the detachable connector 42 is provided on the lower surface of the carrier plate 411. The carrier plate 411 is provided with a first through slot 4111 and a second through slot 4112 for the first hook 4211 and the second hook 4231 to pass through, respectively. This arrangement is intended to facilitate the user to press the first connector 421 when the battery charging box is placed on the upper surface of the carrier plate 411.

[0082] In this embodiment, the second connecting member 423 is a frame-shaped structure. The supporting plate 411 is provided with four first mounting holes 4113. The four corners of the second connecting member 423 are provided with through holes. The second connecting member 423 is fixed to the lower surface of the supporting plate 411 via first fasteners and the first mounting holes 4113. The first fasteners and the second fasteners are both screws.

[0083] Specifically, a sliding assembly opening 4232 is provided on a side wall of the second connecting member 423 away from the second hook 4231. A second partition 4233 is provided within the second connecting member 423. The first connecting member 421 enters or protrudes from the second connecting member 423 through the sliding assembly opening 4232. One end of the spring 422 abuts the second partition 4233, and the other end abuts one end of the first connecting member 421. The number of springs 422 is set to one, two, or three depending on the required elastic force. When the first connecting member 421 is pressed, the first connecting member 421 slides into the second connecting member 423 through the sliding assembly opening 4232, compressing the spring 422. When the pressing force is released, the first connecting member 421 automatically protrudes from the second connecting member 423 under the elastic force of the spring 422.

[0084] In this embodiment, two first hooks 4211 are provided, and the first slot 39 and the first through slot 4111 are elongated holes, whose length direction is the same as the sliding direction of the first connecting member 421. One second hook 4231 is provided, and the width of the second hook 4231 is greater than that of the first hook 4211.

[0085] During assembly, first assemble the first connecting member 421 and the spring 422 on the second connecting member 423, and then fix the second connecting member 423 to the lower surface of the supporting plate 411 through the first fastener. At this time, the first hook 4211 and the second buckle both protrude to the upper surface of the supporting plate 411, and then install the supporting member 41 on the corresponding fixed surface used by the user through the second fastener. Finally, the second hook 4231 is first inserted into the second slot 310, and the first connecting member 421 is pressed to make the first hook 4211 inserted into the first slot 39. After assembly is in place, cancel the pressing force, and the first connecting member 421 is clamped with the bottom plate at the first slot 39 under the elastic force of the spring 422. When the battery charging box needs to be removed from the supporting plate 411, the user presses the first connecting member 421 to cancel the first hook 4211, and then pushes the charging box body toward the vertical plate 412 for a certain distance to cancel the second hook 4231. Finally, the battery charging box can be lifted up to be removed.
