[0030] Reference Figures 1 to 8, an embodiment of the present application provides a screwless installation structure, which may include a box body 1, a mounting plate 2, a movable component, a driving component, and a clamping component. The box body 1 has an open side; the mounting plate 2 is arranged on the open side of the box body 1; the movable component is arranged on the side of the mounting plate 2 facing the box body 1 and is slidably connected to the mounting plate 2. The movable component has a degree of freedom to slide in a first direction, and the first direction is parallel to the plane where the mounting plate 2 is located; the driving component is arranged on the side of the mounting plate 2 facing the box body 1 and is connected to the movable component, and the driving component provides a sliding driving force for the movable component; the clamping component may include a corresponding first clamping member 3 and a second clamping member 4. One of the first clamping member 3 and the second clamping member 4 is arranged on the movable component, and the other is arranged on the open side of the box body 1. Wherein, the first clamping member 3 and the second clamping member 4 are clamped to press the box body 1 and the mounting plate 2 in a second direction, and the second direction intersects with the plane where the mounting plate 2 is located.

[0031] For the screwless installation structure proposed in the embodiment of the present application, when disassembling the mounting plate 2, the driving component drives the movable component to move in the first direction, and the movable component drives the corresponding first clamping member 3 or the second clamping member 4 to move in the first direction, so that the first clamping member 3 and the second clamping member 4 are separated, and the mounting plate 2 can be removed from the box body 1; when installing the mounting plate 2, the mounting plate 2 can be moved to the open side of the box body 1 along the second direction. At this time, the position of the first clamping member 3 corresponds to the position of the second clamping member 4 corresponding to it in the first direction. At this time, the driving component drives the movable component to move in the first direction, and the movable component drives the corresponding first clamping member 3 or the second clamping member 4 to move in the first direction, so that the first clamping member 3 and the second clamping member 4 are clamped, thereby pressing the box body 1 and the mounting plate 2 in the second direction, and the mounting plate 2 and the box body 1 can be connected; compared with the traditional connection scheme of the mounting plate 2 and the box body 1, the disassembly operation is simple, the maintenance work efficiency is high, and at the same time, no exposed screws are used, making the overall structure of the box body 1 more beautiful.

[0032] Wherein, the mounting plate 2 can be a back plate, a top plate, a bottom plate, etc. In other words, any open side of the box body 1 can be connected to the mounting plate 2 through the above structure, and specific selection can be made according to the actual situation. For example, if the internal structure of the box body 1 is simple and the maintenance operation is also relatively simple, the box body 1 can be provided with only one open side and connected to the mounting plate 2, which is convenient for maintenance; if the internal structure of the box body 1 is complex, the box body 1 can be provided with multiple open sides, and the corresponding open sides can be connected to the mounting plate 2 to facilitate more fully exposing the internal structure of the box body 1 for maintenance.

[0033] Further, as Figure 1As shown, the first direction is the X direction and the second direction is the Y direction. For ease of understanding, the rectangular box body 1 will be taken as an example for subsequent description. Then, the first direction X is the same as the height direction of the box body 1, and the second direction Y is the same as the width direction of the box body 1. When the box body 1 is in use, the height direction of the box body 1 can be the same as the direction of gravity, and the second direction Y can be perpendicular to the plane where the mounting plate 2 is located.

[0034] Reference Figures 6 to 8 , in an exemplary embodiment, the movable component may include a guide seat 51 and a guide rail 52. The guide seat 51 is connected to the mounting plate 2, and a through hole 511 extending along the first direction X is provided on the guide seat 51; the guide rail 52 is inserted through the through hole 511 and is slidably connected to the guide seat 51; wherein, a first clamping member 3 or a second clamping member 4 is provided on the guide rail 52, and the guide rail 52 is connected to the driving component.

[0035] Specifically, for ease of explanation, here it is described with the second clamping member 4 provided on the guide rail 52. The driving component drives the guide rail 52 to move along the first direction X. During the movement of the guide rail 52, it relatively slides with the guide seat 51 in the first direction X. The guide rail 52 further drives the second clamping member 4 to move synchronously with the guide rail 52 along the first direction X to drive the second clamping member 4 to be clamped or separated from the corresponding first clamping member 3.

[0036] Among them, the extending direction of the guide rail 52 is the same as the extending direction of the through hole 511. As Figure 6 shown, the guide rail 52 can cooperate with multiple guide seats 51, and the multiple guide seats 51 are spaced apart in the first direction X. In this way, the guide rail 52 has multiple support points in the first direction X, making the sliding process of the guide rail 52 along the first direction X more stable.

[0037] In an exemplary embodiment, there are two guide rails 52 and they are oppositely arranged in the third direction. Each guide rail 52 is connected to the driving component, and the third direction intersects with the first direction X and the second direction Y.

[0038] In an exemplary embodiment, there are multiple groups of clamping components, and the first clamping member 3 or the second clamping member 4 in each group of clamping components is spaced apart along the first direction X on each guide rail 52.

[0039] Specifically, as Figure 6 shown, the third direction is the Z direction, and the third direction Z is the same as the length direction of the box body 1. The two guide rails 52 are oppositely arranged in the third direction Z. In this way, when installing the mounting plate 2, the two guide rails 52 drive the corresponding first clamping member 3 and / or the second clamping member 4 to move along the first direction X when moving along the first direction X to connect the mounting plate 2 and the box body 1, and the connection area between the mounting plate 2 and the box body 1 is the area where each group of clamping components is located. In this way, the mounting plate 2 is connected to the box body 1 at multiple positions in the first direction X and the third direction Z, and the connection is more stable.

[0040] It should be understood that the number of guide rails 52 can be further increased. The more the number of guide rails 52, the more the multiple guide rails 52 are connected to the box body 1 through the clamping components, making the connection between the mounting plate 2 and the box body 1 more stable. However, setting two guide rails 52 is sufficient to stably connect the mounting plate 2 and the box body 1. Therefore, only two guide rails 52 are set in this application to save costs on the premise of ensuring stable connection.

[0041] It should be noted that there are three setting methods for each clamping component: First, the first clamping part 3 in each clamping component is arranged on the mounting plate 2, and the second clamping part 4 is arranged on the open side of the box body 1; Second, the second clamping part 4 in each clamping component is arranged on the mounting plate 2, and the first clamping part 3 is arranged on the open side of the box body 1; Third, both the first clamping part 3 and the second clamping part 4 are arranged on the mounting plate 2.

[0042] Reference Figure 8 , in the exemplary embodiment, one side of the guide seat 51 in the third direction Z has a notch 512, and the through hole 511 communicates with the notch 512. The third direction Z intersects with the first direction X and the second direction Y; wherein, the notch 512 is located on the moving path of the first clamping part 3 and / or the second clamping part 4.

[0043] Specifically, as Figure 8 shown, the guide rail 52 passes through the through hole 511 and is slidably matched with the guide seat 51, and the notch 512 is located on the moving path of the first clamping part 3 and / or the second clamping part 4, that is, when the first clamping part 3 or the second clamping part 4 moves along the first direction X, it can pass through the notch 512 to prevent the guide seat 51 from blocking the first clamping part 3 and the second clamping part 4, ensuring that the first clamping part 3 or the second clamping part 4 can move normally along the first direction X; at the same time, when connecting the guide seat 51 and the guide rail 52, one guide rail 52 can be inserted into the through holes 511 of multiple guide seats 51, and the positions of the guide seats 51 can be adjusted in the first direction X, so that it is more convenient to install the guide rail 52 and the guide seat 51 on the mounting plate 2.

[0044] It should be noted that on the same guide rail 52, each first clamping part 3 and / or second clamping part 4 is located on the side of the corresponding guide rail 52 facing the notch 512 to ensure that each first clamping part 3 and / or second clamping part 4 can pass through the notch 512.

[0045] Reference Figure 1 、 Figures 6 to 8, in an exemplary embodiment, the driving assembly may include a cross beam 61, a moving beam 62, and a screw 63. The cross beam 61 is located at one end of the guide rail 52 and is connected to the mounting plate 2; the moving beam 62 is located on the side of the cross beam 61 facing the guide rail 52 and is connected to the guide rail 52; the axial direction of the screw 63 is the same as the first direction X and penetrates through the cross beam 61 and the moving beam 62. The screw 63 is rotatably connected to the cross beam 61 and has the freedom to rotate about its own axis, and the screw 63 is threadedly connected to the moving beam 62.

[0046] Specifically, the rotation of the screw 63 drives the moving beam 62 to move along the first direction X, and the moving beam 62 further drives each guide rail 52 to move along the first direction X, so as to connect or separate the box body 1 and the mounting plate 2 through the clamping assembly.

[0047] Among them, as Figure 2 shown, the driving assembly can be arranged at the lower end or the upper end of the guide rail 52. In the embodiment of the present application, the driving assembly is arranged at the upper end of the guide rail 52, so that it is convenient to operate the driving assembly; as Figure 2 shown, after the mounting plate 2 is connected to the box body 1, the highest point of the mounting plate 2 is located outside the box body 1. The top end of the screw 63 is the driving end of the screw 63. In other words, the screw 63 can be driven to rotate through the top end of the screw 63, and the top end of the screw 63 is also located outside the box body 1, so that it is convenient to rotate the screw 63.

[0048] Furthermore, as Figure 1 shown, a cover plate 7 is further arranged on the top of the box body 1. The cover plate 7 covers the part of the mounting plate 2 that extends beyond the box body 1, making the overall screwless mounting structure more tidy and beautiful. The cover plate 7 can be connected to the box body 1 through hidden screws. As Figure 1 shown, the hidden screws on the cover plate 7 are all arranged in the holes on the cover plate 7, so as to ensure that the overall screwless mounting structure is more tidy and beautiful.

[0049] Even further, no hidden screws are arranged on the cover plate 7, and a groove is arranged on the side of the cover plate 7 facing the box body 1. The part of the mounting plate 2 that extends beyond the box body 1 is matched with the groove to realize the installation and disassembly of the cover plate 7. In this way, the installation or disassembly operation of the mounting plate 2 is still simple, and at the same time, the aesthetic degree of the overall screwless mounting structure is ensured.

[0050] Referring to Figure 5 , in an exemplary embodiment, the first clamping member 3 has a clamping groove. One end of the clamping groove in the first direction X is an open end, and the other end is a closed end; among them, when the second clamping member 4 is located at the closed end, the box body 1 and the mounting plate 2 are pressed tightly in the second direction Y.

[0051] Specifically, as Figure 5As shown, the clamping groove penetrates through opposite sides of the first clamping member 3 in the third direction Z. After the second clamping member 4 moves from the open end to the closed end of the clamping groove along the first direction X, the box body 1 and the mounting plate 2 are pressed tightly in the second direction Y, and thus the mounting plate 2 can be connected to the box body 1.

[0052] In an embodiment of the present application, it is described with the first clamping member 3 provided on the box body 1 and the second clamping member 4 provided on the guide rail 52. If the open end of the clamping groove faces downward, at this time, the mounting plate 2 is arranged at the open end of the box body 1 along the second direction Y, and the second clamping member 4 is located below the corresponding first clamping member 3. Rotating the screw 63 drives the moving beam 62 and the guide rail 52 to move upward along the first direction X, and the second clamping member 4 moves to the closed end of the corresponding clamping groove. At this time, the first clamping member 3 is clamped with the corresponding second clamping member 4, and the mounting plate 2 is connected to the box body 1. Rotating the screw 63 in the reverse direction will separate the mounting plate 2 from the box body 1; if the open end of the clamping groove faces upward, at this time, the mounting plate 2 is arranged at the open end of the box body 1 along the second direction Y, and the second clamping member 4 is located above the corresponding first clamping member 3. Rotating the screw 63 drives the moving beam 62 and the guide rail 52 to move downward along the first direction X, and the second clamping member 4 moves to the closed end of the corresponding clamping groove. At this time, the first clamping member 3 is clamped with the corresponding second clamping member 4, and the mounting plate 2 is connected to the box body 1. Rotating the screw 63 in the reverse direction will separate the mounting plate 2 from the box body 1.

[0053] In another embodiment of the present application, it is described with the first clamping member 3 provided on the guide rail 52 and the second clamping member 4 provided on the box body 1. If the open end of the clamping groove faces downward, at this time, the mounting plate 2 is arranged at the open end of the box body 1 along the second direction Y, and the second clamping member 4 is located below the corresponding first clamping member 3. Rotating the screw 63 drives the moving beam 62 and the guide rail 52 to move downward along the first direction X, and the first clamping member 3 moves synchronously so that the second clamping member 4 is located at the closed end of the corresponding clamping groove. At this time, the first clamping member 3 is clamped with the corresponding second clamping member 4, and the mounting plate 2 is connected to the box body 1. Rotating the screw 63 in the reverse direction will separate the mounting plate 2 from the box body 1; if the open end of the clamping groove faces upward, at this time, the mounting plate 2 is arranged at the open end of the box body 1 along the second direction Y, and the second clamping member 4 is located above the corresponding first clamping member 3. Rotating the screw 63 drives the moving beam 62 and the guide rail 52 to move upward along the first direction X, and the first clamping member 3 moves synchronously so that the second clamping member 4 is located at the closed end of the corresponding clamping groove. At this time, the first clamping member 3 is clamped with the corresponding second clamping member 4, and the mounting plate 2 is connected to the box body 1. Rotating the screw 63 in the reverse direction will separate the mounting plate 2 from the box body 1.

[0054] In yet another embodiment of the present application, a first clamping member 3 and a second clamping member 4 are simultaneously provided on the guide rail 52. Specifically, the open end of the clamping groove on the first clamping member 3 faces downward or upward, and the cases where the first clamping member 3 is provided on the guide rail 52 or on the box body 1 have been described above. Here, for how the first clamping member 3 and the second clamping member 4 provided on the guide rail 52 are specifically connected to the corresponding second clamping member 4 and first clamping member 3 respectively, reference may be made to the above content, and details will not be elaborated here.

[0055] Among them, as Figure 8 shown, the second clamping member 4 can be a pin shaft, and its axial direction is the same as the third direction Z.

[0056] In an exemplary embodiment, the clamping groove has an inclined wall surface 31 and a straight wall surface 32 that are oppositely arranged in the second direction Y. Among them, when the first clamping member 3 is provided on the box body 1, the inclined wall surface 31 is located between the straight wall surface 32 and the mounting plate 2; when the first clamping member 3 is provided on the mounting plate 2, the straight wall surface 32 is located between the inclined wall surface 31 and the mounting plate 2; from the open end to the closed end of the clamping groove, the distance between the inclined wall surface 31 and the straight wall surface 32 gradually decreases in the second direction Y, and the straight wall surface 32 is parallel to the plane where the mounting plate 2 is located.

[0057] Specifically, taking the case where the first clamping member 3 is provided on the box body 1 and the second clamping member 4 is provided on the guide rail 52 as an example, during the process that the driving assembly drives the second clamping member 4 to move along the first direction X from the open end to the closed end of the clamping groove, the second clamping member 4 abuts against the inclined wall surface 31. During the movement of the second clamping member 4, it gradually approaches the straight wall surface 32, and the first clamping member 3 remains stationary. Then, the second clamping member 4 will drive the mounting plate 2 and the box body 1 to gradually fit and press tightly, ensuring the sealing effect between the mounting plate 2 and the box body 1 and preventing problems such as water leakage.

[0058] Furthermore, taking the case where the first clamping member 3 is provided on the guide rail 52 and the second clamping member 4 is provided on the box body 1 as an example, when the driving assembly drives the first clamping member 3 to move along the first direction X, such that the second clamping member 4 moves from the open end to the closed end of the clamping groove relative to the first clamping member 3, the inclined wall surface 31 of the first clamping member 3 abuts against the second clamping member 4. During the movement of the first clamping member 3, the straight wall surface 32 gradually approaches the second clamping member 4, and the second clamping member 4 remains stationary. Then, the first clamping member 3 will drive the mounting plate 2 and the box body 1 to gradually fit and press tightly, ensuring the sealing effect between the mounting plate 2 and the box body 1 and preventing problems such as water leakage.

[0059] It should be noted that a first clamping member 3 and a second clamping member 4 are simultaneously provided on the guide rail 52. For the specific working principle, reference may be made to the above content.

[0060] Further, a sealing ring may be provided on the mounting plate 2 or the box body 1. When the mounting plate 2 is attached to and pressed against the box body 1, the sealing ring is squeezed, further improving the sealing effect between the box body 1 and the mounting plate 2.

[0061] In an exemplary embodiment, both the first engaging member 3 and the second engaging member 4 are located on the opposite sides of the two guide rails 52; wherein, in the third direction Z, when the first engaging member 3 is located on the guide rail 52, the first engaging member 3 abuts against the side wall of the box body 1; in the third direction Z, when the first engaging member 3 is located on the box body 1, the first engaging member 3 abuts against the guide rail 52.

[0062] Specifically, the first engaging members 3 provided on the two opposite sides in the third direction Z, whether provided on the guide rail 52 or the box body 1, can limit the two guide rails 52 from sliding relative to the box body 1 in the third direction Z, preventing the mounting plate 2 from sliding in the third direction Z, making the connection of the mounting plate 2 more stable.

[0063] Among them, in the third direction Z, taking the mounting plate 2 sliding to one side as an example, at the corresponding side, if the first engaging member 3 is provided on the box body 1, the first engaging member 3 does not move and prevents the guide rail 52 from moving, further preventing the mounting plate 2 from sliding; if the first engaging member 3 is provided on the guide rail 52 and the box body 1 does not move, the first engaging member 3 is blocked by the box body 1 from moving, further preventing the mounting plate 2 from sliding.

[0064] In an alternative embodiment, as Figure 1 and Figure 3 shown, flanging structures may be provided at both sides of the open side of the box body 1, so that the mounting plate 2 is snapped into the flanging structures, thus preventing the mounting plate 2 from sliding in the third direction Z.

[0065] It should be understood that a flanging structure may also be provided below the open side of the box body 1 to prevent the mounting plate 2 from sliding downward along the first direction X, and the cover plate 7 on the top of the box body 1 can prevent the mounting plate 2 from moving upward along the first direction X. If the flanging structure and the box body 1 are regarded as a whole, it can be regarded as a groove being opened on the side wall of the box body 1, and this groove communicates with the internal space of the box body 1. The mounting plate 2 is arranged in this groove, and the mounting plate 2 is connected to the box body 1 through a clamping component.

[0066] Among them, when the box body 1 is arranged on the ground, even if no flanging structure is provided below the open side of the box body 1, the mounting plate 2 will be blocked by the ground and cannot slide downward; in addition, after the mounting plate 2 is attached to and pressed against the box body 1 in the second direction Y, the mounting plate 2 naturally cannot slide along the first direction X or the third direction Z.

[0067] Based on the above embodiments, the embodiment of the present application further provides a charging device, and the charging device may include the above screwless mounting structure.

[0068] Specifically, the charging device can be a charging pile. Then, the box body 1 is the outer shell of the charging pile, and the mounting plate 2 can be the back plate of the charging pile. By disassembling the back plate, it is convenient to maintain the internal structure of the charging pile.

[0069] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present application.
