The back plate body 400 has at least one through hole 402, through which a fixing member passes to fix the back plate body 400 to the vertical wall; the fixing member can be an expansion screw or a bolt, etc. In this embodiment, for example, the back plate body 400 has one through hole 402 near the upper part and one near the lower part, and the back plate body 400 is fixed and suspended on the wall by bolts. In other embodiments, the through holes may also be provided at other locations on the back plate body 400, as long as they can be used to fix the back plate body 400 to the vertical wall. The present invention does not limit this.

[0107] Please see Figures 19 to 21 In some embodiments, the backplate body 400 may include a slide rail 403 and a locking structure. The locking structure includes at least a first locking position 404 and a second locking position 405. In some embodiments, there may be multiple slide rails 403, which are vertically fixed to the backplate body 400, allowing the object to be suspended to slide along the slide rails 403 and thus be fixed to the backplate body 400. In this embodiment, the slide rail 403 includes a first slide rail and a second slide rail, which are symmetrically arranged on the backplate body 400. For example, the first slide rail and the second slide rail are symmetrically arranged on both sides of the backplate body 400 and are parallel to the plane on which the backplate body 400 is located.

[0108] Please see Figures 19 to 21 In some embodiments, the slide 403 can be a raised structure, while in other embodiments, the slide 403 can also be a groove structure or a magnetic structure. The slide 403 here only needs to enable the object to be suspended to slide on the slide 403, and the specific form of the slide 403 is not limited.

[0109] Please see Figures 19 to 21In some embodiments, the backplate body 400 is further provided with a first locking position 404. In this embodiment, the first locking position 404 is disposed between the slide rails 403 on both sides of the backplate body 400, and is located on one side of the slide rails 403. In other embodiments, the first locking position 404 can also be disposed at other positions on the backplate body 400, such as in the middle of the two slide rails 403, as long as the first locking position 404 can fix the object to be suspended. The specific placement of the first locking position 404 is not limited in this invention. The first locking position 404 is used to fix the vertical position of the object to be suspended on the backplate body 400.

[0110] Please see Figures 19 to 21 In some embodiments, the first locking position 404 can be a movable locking position, specifically allowing the first locking position 404 to move away from the back plate mating body 401 under the action of an external force. In this embodiment, the side of the first locking position 404 near the slide rail 403 is connected to the back plate body 400, while the other side of the first locking position 404 is freely suspended. When an external force is applied to the side of the first locking position 404 away from the back plate body 400, the first locking position 404 on this side can move away from the back plate mating body 401. When the external force is removed, the side of the first locking position 404 away from the back plate body 400 returns to its original position, thereby realizing the connection and fixation of the object to be suspended to the back plate body 400.

[0111] Please see Figures 19 to 21 In some embodiments, the second locking position 405 may be located on the side of the back panel body 400 near the bottom.

[0117] Please refer to the following: Figures 19 to 22 The number of mating slides 139 can be set according to the number of slides 403 on the back plate body 400. In this embodiment, since the slides 403 on the back plate body 400 include a first slide and a second slide, the mating slides 139 also include a first mating slide and a second mating slide. The first mating slide and the second mating slide are symmetrically arranged on both sides of the back plate mating body 401 and respectively mate with the first slide and the second slide, allowing the slide 403 to slide within the mating slides 139.

[0118] Please refer to the following: Figures 19 to 22In some embodiments, the sliding track 139 can be a protruding structure, while in other embodiments, the sliding track 139 can also be a groove structure or a magnetic structure. The sliding track 139 here can be used to cooperate with the sliding track 403 so that the object to be suspended can slide on the sliding track 403. The specific form of the sliding track 139 is not limited.

[0119] Please refer to the following: Figures 19 to 22 Specifically, for example, slide 403 is a raised structure, and slide 139 is a recessed structure. More specifically, for example, a raised structure can be provided on each side of the back plate body 400, and correspondingly, two recessed structures are provided on the object to be hung. The size of the recessed structure matches the size of the raised structure, allowing the two raised structures on the back plate body 400 to slide in the recessed structure. In this embodiment, the raised structure is, for example, a strip-shaped structure protruding from the surface of the back plate body 400. In other embodiments, the raised structure can also be a protruding dot structure protruding from the surface of the back plate body 400, or a raised structure of other shapes. In this invention, the shape of the raised structure is not specifically limited, as long as it can achieve sliding by embedding the raised structure into the corresponding recessed structure. In some embodiments, the length of the raised structure can be the same as the side length of the back plate body 400. In other embodiments, the length of the raised structure can also be less than the side length of the back plate body 400.

[0120] Please refer to the following: Figures 19 to 22 In some embodiments, when the back plate body 400 is provided with a first locking position 404, a corresponding first locking groove 140 is provided on the back plate mating body 401. In this embodiment, the first locking groove 140 is located on one side of the mating slide 139 and cooperates with the first locking position 404, allowing the first locking position 404 to be embedded in the first locking groove 140. In other embodiments, the specific position of the first locking groove 140 can be set according to the position of the first locking position 404, which is not limited in this invention.

[0121] Please refer to the following: Figure 2 , Figures 19 to 22 In some embodiments, a release button 408 is provided on the side of the first locking slot 140 away from the back plate body 400. When the object to be hung is fixed on the back plate body 400, the release button 408 is pressed. Under the action of the release button 408, the first locking slot 404 moves away from the back plate mating body 401, thereby causing the first locking slot 404 to disengage from the first locking slot 140, thus completing the disassembly process between the back plate body 400 and the back plate mating body 401. In addition, the object to be hung can be detached from the back plate body 400.

[0122] Please refer to the following: Figures 19 to 22In some embodiments, when the backplate body 400 is provided with a second locking position 405, a corresponding second locking groove 142 is provided on the backplate mating body 401. In this embodiment, the second locking groove 142 is located on the side of the backplate mating body 401 near the bottom. In other embodiments, the position of the second locking groove 142 can be determined according to the position of the second locking position 405. The second locking groove 142 cooperates with the second locking position 405, allowing the second locking position 405 to be embedded in the second locking groove 142. Under the cooperation of the second locking position 405 and the second locking groove 142, the backplate body 400 is prevented from sliding relative to the backplate mating body 401, thereby fixing the object to be hung to the backplate body 400. In some embodiments, when the second locking position 405 is a movable locking position, a release button can also be provided on the side of the second locking groove 142 away from the backplate body 400 for pressing the second locking position 405.

[0123] Please see Figure 2 , Figures 23 to 24 The backplate fitting 401 can be a separate component or part of the charging device 1.

The sliding ribs in the second locking unit 502 are staggered with the sliding ribs in the first locking unit 501. When the first locking unit 501 and the second locking unit 502 are closed, the sliding ribs and sliding ribs in the two locking units form an interlocking structure, making the connection between the first locking unit 501 and the second locking unit 502 more stable after they are closed.

[0134] Please refer to the following: Figure 27 and Figure 28 In this embodiment, based on the number of sliding ribs in the first locking unit 501, the second locking unit 502 is provided with, for example, two first-level sliding ribs 507 and two second-level sliding ribs 508. The first-level sliding ribs 507 and the second-level sliding ribs 508 are parallel to the sliding ribs, and the first-level sliding ribs 507 and the second-level sliding ribs 508 are parallel to each other.

[0135] Please refer to the following: Figure 27 and Figure 28 When the first locking unit 501 and the second locking unit 502 are closed, the first sliding rib 505 and the first mating sliding rib 507 interlock, and the second sliding rib 506 and the second mating sliding rib 508 interlock. When the charging device 1 is connected to the fixed base 520, the first sliding rib 505 and the first mating sliding rib 507, and the second sliding rib 506 and the second mating sliding rib 508 interlock and cooperate simultaneously, so that the charging device 1 and the fixed base 520 are stably connected, improving the strength of the structure. Moreover, the interlocking cooperation between the first sliding rib 505 and the first mating sliding rib 507, and the second sliding rib 506 and the second mating sliding rib 508 can ensure that the structure is not easy to shake.

[0136] Please refer to the following: Figure 27 and Figure 28 In some embodiments, the lengths of the multiple mating sliding ribs may be different. The length of the mating sliding rib can be determined based on the length of the mating sliding rib and the external dimensions of the second locking unit 502. It is only necessary to ensure that the sliding rib and the mating sliding rib are interlocked without gaps. In this embodiment, for example, when the first locking unit 501 and the second locking unit 502 are closed, the length of the first mating sliding rib 507 is greater than the length of the second mating sliding rib 508.

[0137] Please refer to the following: Figure 27 and Figure 28 In some embodiments, the second locking unit 502 is further provided with a third sliding rib 534 for interlocking with the third sliding rib 518 in the first locking unit 501, so as to further improve the structural strength and stability of the locking structure.

[0138] Please refer to the following: Figures 28 to 31 In some embodiments, the second locking unit 502 may further include a locking base 509, a locking cover plate 513, and a latching structure 530. The locking base 509 is, for example, L-shaped. The portion of the L-shaped locking base 509 parallel to the plane of the fixed base 520 is defined as the horizontal portion 531, and the portion of the L-shaped locking base 509 perpendicular to the plane of the fixed base 520 is defined as the vertical portion 532. A latching button hole 533 is provided on the vertical portion 532. Multiple sliding ribs are symmetrically distributed on both sides of the latching button hole 533, and one end of the sliding rib is fixed to the side surface of the vertical portion 532 adjacent to the horizontal portion 531. The extending direction of the sliding rib is parallel to the horizontal portion 531. For example, two first sliding ribs 507 are located on both sides of the locking base 509, two second sliding ribs 508 are located on both sides of the locking base 509, and two third sliding ribs 534 are located on both sides of the locking base 509. In this embodiment, one end of the first sliding rib 507, the second sliding rib 508, and the third sliding rib 534 is fixed on the vertical part 532, and they are arranged sequentially along the side of the vertical part 532 away from the horizontal part 531 towards the horizontal part 531. The first sliding rib 507, the second sliding rib 508, and the third sliding rib 534 are parallel to each other and parallel to the horizontal part 531. In this embodiment, the length of the first sliding rib 507 is greater than the length of the second sliding rib 508 and less than the length of the third sliding rib 534.

[0139] Please refer to the following: Figures 28 to 31The distance between the two first sliding ribs 507 is, for example, 20mm-50mm, preferably 30mm-40mm, specifically 38.6mm. The distance between the two first sliding ribs 507 can be less than the distance between the two first sliding ribs 505. The distance between the two second sliding ribs 508 is, for example, 30mm-60mm, preferably 40mm-50mm, specifically 46.8mm. The distance between the two second sliding ribs 508 can be less than the distance between the two second sliding ribs 506. The distance between the first sliding rib 507 and the second sliding rib 508 is, for example, 1mm-5mm, preferably 2mm-4mm, specifically 2.8mm. The distance between the first sliding rib 507 and the second sliding rib 508 can be less than the distance between the first sliding rib 505 and the second sliding rib 506. The distance between the second sliding rib 508 and the third sliding rib 534 is 2mm-8mm, preferably 3-7mm, specifically 3mm. The distance between the second sliding rib 508 and the third sliding rib 534 can be less than the distance between the second sliding rib 506 and the third sliding rib 518.

[0140] Please see Figure 29 In some embodiments, a rib 535 may be provided on one side of the sliding rib adjacent to the latch button hole 533 along the extension direction of the sliding rib. The shape of the rib 535 is not specifically limited here. In some embodiments, ribs 535 may be provided on all sides of the sliding rib. In other embodiments, ribs 535 may be provided on only some sides of the sliding rib. In this embodiment, for example, a rib 535 is provided on one side of the latch button hole 533 along the extension direction of the first sliding rib 507 and the second sliding rib 508.

[0141] Please see Figures 28 to 30 The second locking unit 502 may further include a locking cover plate 513. The locking cover plate 513, together with the vertical portion 532 and the horizontal portion 531 of the locking base 509, forms a closed cavity. Specifically, the locking cover plate 513 has groove-shaped structures 536 on both sides that mate with the protruding ribs 535 on the sides of the sliding ribs. Horizontally moving the locking cover plate 513 causes the protruding ribs 535 to insert into the groove-shaped structures 536, thereby tightly engaging the locking cover plate 513 with the locking base 509. A locking hole 514 is provided on the side of the locking cover plate 513 away from the horizontal portion 531 of the locking base 509.

[0142] Please see Figure 28 , Figure 29 and Figure 31The locking structure 530 includes a button 512, a tongue-shaped protrusion 516, and a locking block 504. The button 512 is fitted into the locking button hole 533, allowing the button 512 to slide relative to the locking button hole 533. One end of the tongue-shaped protrusion 516 is connected to the side of the button 512 adjacent to the closed cavity, and the other end of the tongue-shaped protrusion 516 is located on the side of the locking hole 514 away from the vertical portion 532. The tongue-shaped protrusion 516 forms an inclined angle with the horizontal direction away from the vertical portion 532, and the inclined angle ranges from 0 to 90°. In this embodiment, the inclined angle is, for example, 45°. In this embodiment, the end face of the other end of the tongue-shaped protrusion 516 is parallel to the vertical portion 532. The locking block 504 is fitted onto the tongue-shaped protrusion 516 and is vertically positioned. One end of the locking block 504 is aligned with the locking hole 514, and this end can extend and retract within the locking hole 514. The end of the locking block 504 near the locking hole 514 is beveled to facilitate engagement with the latch groove 503 on the first locking unit 501. The button 512 slides relative to the latch button hole 533, causing the tongue-shaped protrusion 516 to move horizontally. Because the tongue-shaped protrusion 516 is inclined upwards, the distance between the locking block 504 and the tongue-shaped protrusion 516 and the horizontal portion 531 of the locking base 509 continuously changes. This causes the end of the locking block 504 near the locking hole 514 to extend and retract within the locking hole 514, meaning the end of the locking block 504 near the locking hole 514 is either lower or higher than the locking hole 514. When one end of the hole 514 is higher than the locking hole 514, the locking block 504 is at least partially exposed in the locking hole 514. The width of the locking block 504 is, for example, 16mm-25mm, preferably 18mm-23mm, specifically, for example, 21mm. The distance from the locking block 504 to the vertical part 532 is 8mm-15mm, preferably 10mm-13mm, specifically, for example, 11.6mm. The thickness of the locking block 504 is, for example, 2mm-6mm, preferably 3mm-5mm, specifically, for example, 4.4mm.

[0143] Please see Figure 28 , Figure 29 and Figure 31 Specifically, when button 512 moves the tongue-shaped protrusion 516 closer to the latch button hole 533, the engagement point between the locking block 504 and the tongue-shaped protrusion 516 moves away from the horizontal portion 531 of the locking base 509, and the locking block 504 moves towards the locking hole 514, thus exposing the locking block 504 in the locking hole 514. When button 512 moves the tongue-shaped protrusion 516 away from the latch button hole 533, the engagement point between the locking block 504 and the tongue-shaped protrusion 516 moves closer to the horizontal portion 531 of the locking base 509, and the locking block 504 moves away from the locking hole 514, so that the beveled end face of the locking block 504 is flush with the plane of the locking hole 514.

[0144] Please see Figure 28 , Figure 29 , Figures 31 to 33 In some embodiments, the second locking unit 502 further includes a spring element (not shown), which is disposed on the side of the tongue-shaped protrusion 516 near the horizontal portion 531 of the locking base 509. The spring element is connected between the button 512 and the locking cover plate 513, and the direction of the spring force of the spring element is parallel to the horizontal portion 531 of the locking base 509. The spring element is, for example, a spring. In this embodiment, the button 512 pulls or pushes the tongue-shaped protrusion 516 by the stretching or compression of the spring, thereby moving the tongue-shaped protrusion 516 closer to or further away from the latch button hole 533.

[0145] Please see Figures 26 to 33In use, with the locking structure 530 in its initial position, the second locking unit 502 moves horizontally along the first locking unit 501. During this movement, the multiple sliding ribs in the first locking unit 501 interlock with the multiple mating sliding ribs in the second locking unit 502. When the inclined end face of the locking block 504 contacts the bottom surface of the charging device 1, under the pressure of the bottom surface of the charging device 1, the locking block 504 gradually moves away from the bottom surface of the charging device 1. The locking block 504 and the tongue protrusion... The joint of part 516 moves closer to the horizontal part 531 of the locking base 509, thereby driving the tongue-shaped protrusion 516 to move away from the latch button hole 533. At this time, the elastic element gradually changes from the initial state to the compressed state until the locking block 504 is lowered to a position flush with the plane of the locking hole 514. The second locking unit 502 and the first locking unit 501 continue to move relative to each other in the horizontal direction. When the end of the locking block 504 near the locking hole 514 is aligned with the latch groove 503 on the bottom surface of the charging device 1, the bottom of the charging device 1... As the pressure on the locking block 504 disappears, the spring element gradually resets, returning from its compressed state to its initial state. The spring element pushes the button 512 towards the latch button hole 533. The movement of the button 512 causes the tongue-shaped protrusion 516 to move closer to the latch button hole 533. The junction between the locking block 504 and the tongue-shaped protrusion 516 gradually moves away from the horizontal part 531 of the locking base 509. Then, the locking block 504 moves towards the locking hole 514 until the spring element has fully reset, and the latch structure 530... Returning to the initial position, the locking block 504 exposes the locking hole 514 and is inserted into the locking groove 503, thus fixing the first locking unit 501 and the second locking unit 502. Due to the interlocking and cooperation of the multiple sliding ribs in the first locking unit 501 and the multiple cooperating sliding ribs in the second locking unit 502, the locking structure 522 has good structural strength and small gaps, which avoids shaking after the first locking unit 501 and the second locking unit 502 are fixedly locked, thus improving the stability and safety of the structure.

[0146] Please see Figures 26 to 33When it is necessary to disengage the first locking unit 501 and the second locking unit 502, the button 512 can be pressed. Pressing the button 512 will cause the tongue-shaped protrusion 516 to gradually move away from the locking button hole 533. The elastic element will gradually change from the initial state to the compressed state. The joint between the locking block 504 and the tongue-shaped protrusion 516 will gradually approach the horizontal part 531 of the locking base 509. The locking block 504 will gradually move away from the locking hole 514, so that the locking block 504 is lowered to a position flush with the plane where the locking hole 514 is located. At this time, the first locking unit 501 and the second locking unit 502 will be disengaged. The first locking unit 501 and the second locking unit 502 will be moved in opposite directions along the horizontal direction, so that the multiple sliding ribs in the first locking unit 501 will disengage from the multiple mating sliding ribs in the second locking unit 502, thereby realizing the disengagement of the first locking unit 501 and the second locking unit 502.
