[0031] Reference Figures 1-8 The embodiments of the present application provide an outer cover connecting structure, which can include a front shell 1 and an outer cover plate 2 stacked in a first direction. The side of the front shell 1 facing the outer cover plate 2 is provided with a first limiting groove 11 and a second limiting groove 12. The second limiting groove 12 penetrates the side of the front shell 1 and communicates with the first limiting groove 11. The outer cover connecting structure can also include a first limiting portion 13, a second limiting portion 14, a first clamping plate 3, a first clamping piece 31 and a second clamping piece 32. The first limiting portion 13 is arranged on the side wall of the first limiting groove 11 opposite the second limiting groove 12 and located at the slot of the first limiting groove 11. The second limiting portion 14 is arranged in the second limiting groove 12. The first clamping plate 3 is arranged on the side of the outer cover plate 2 facing the front shell 1 and located in the first limiting groove 11. In the second direction, both sides of the first clamping plate 3 are in contact with the side wall of the first limiting groove 11. In the third direction, the first clamping plate 3 is in contact with the first limiting portion 13. The third direction, the second direction and the first direction intersect with each other. The first clamping piece 31 is connected to the side of the first clamping plate 3 away from the outer cover plate 2 and extends out of the side of the first clamping plate 3. In the first direction, the first clamping piece 31 is in contact with the first limiting portion 13. The second clamping piece 32 is elastically connected to the side of the first clamping plate 3 away from the first limiting portion 13 and located in the second limiting groove 12. The second clamping piece 32 has a gap with the outer cover plate 2 in the first direction. The side of the second clamping piece 32 away from the outer cover plate 2 has a protruding portion 321. In the third direction, the protruding portion 321 is located between the first limiting portion 13 and the second limiting portion 14 and in contact with the second limiting portion 14.

[0032] The outer cover connecting structure provided by the embodiment of the application is used for connecting the outer cover plate 2 and the front shell 1. When the outer cover plate 2 is connected with the front shell 1, in the first direction, the outer cover plate 2 is attached to the front shell 1, and meanwhile, the first clamping piece 31 is in abutment with the first limiting part 13, so that the outer cover plate 2 cannot move in the first direction. In the second direction, the two side parts of the first clamping plate 3 are in abutment with the side walls of the first limiting slot 11, so that the outer cover plate 2 cannot move in the second direction. In the third direction, the first clamping plate 3 is in abutment with the first limiting part 13, and the protruding part 321 on the second clamping piece 32 is in abutment with the second limiting part 14, so that the outer cover plate 2 cannot move in the third direction, thereby limiting the relative position of the outer cover plate 2 and the front shell 1. When the outer cover plate 2 is disassembled, a slot screw cutter can be inserted into the second limiting slot 12 from the edge of the front shell 1, and the second clamping piece 32 is pressed against and lifted up, so that the second clamping piece 32 moves away from the front shell 1 in the first direction, and the second clamping piece 32 drives the protruding part 321 to separate from the second limiting part 14. At this time, the first clamping plate 3 can move away from the first limiting part 13 in the third direction, until the first clamping piece 31 is no longer in abutment with the first limiting part 13 in the first direction. At this time, the outer cover plate 2 can be removed along the first direction. The disassembly operation is convenient and fast, and the outer cover plate 2 is convenient to maintain. Meanwhile, the outer cover plate 2 does not need to be connected by using a screw, and the overall structure of the outer cover plate 2 is more beautiful and neat.

[0033] It should be noted that the outer cover plate 2 in the application is taken as an example for description. The outer cover plate 2 has a length, a width and a thickness, and the length of the outer cover plate 2 is greater than or equal to the width. The length direction, the width direction and the thickness direction of the outer cover plate 2 are perpendicular to each other. The first direction is the thickness direction of the outer cover plate 2, the second direction is the width direction of the outer cover plate 2, and the third direction is the length direction of the outer cover plate 2. In addition, for the convenience of description, the third direction is taken as the same as the direction of gravity, and the second limiting part 14 is taken as the reference above the first limiting part 13 for description.

[0034] Specifically, when the outer cover plate 2 is connected with the front shell 1, the outer cover plate 2 can be moved in the first direction, so that the first clamping plate 3 enters the first limiting slot 11. Figure 7As shown, at this time, the first clamping piece 31 is located in the first limiting groove 11, the two side portions of the first clamping plate 3 abut against the first limiting groove 11, the first clamping plate 3 cannot move in the second direction, the first clamping plate 3 is connected with the outer decorative plate 2, and thus the outer decorative plate 2 cannot move in the second direction; then the outer decorative plate 2 is slid downward, the outer decorative plate 2 drives the first clamping plate 3, the first clamping piece 31 and the second clamping piece 32 to move synchronously, the protruding portion 321 is extruded by the second limiting portion 14 to drive the second clamping piece 32 to move close to the outer decorative plate 2, the second clamping piece 32 is deformed and is subjected to elastic force, when the protruding portion 321 moves below the second limiting portion 14, the protruding portion 321 is no longer extruded by the second limiting portion 14, the second clamping piece 32 is restored to the undeformed state by the elastic force of the second clamping piece 32 and drives the protruding portion 321 to move away from the outer decorative plate 2, so that the protruding portion 321 abuts against the second limiting portion 14 in the third direction, at this time, the first clamping plate 3 abuts against the first limiting portion 13 in the third direction, and the second clamping piece 32 abuts against the first limiting portion 13 in the first direction, as shown in Figure 4 Thus, the first clamping plate 3 cannot move in the first direction and the third direction, so that the outer decorative plate 2 cannot move in the first direction and the third direction, and finally the relative position of the outer decorative plate 2 and the front shell 1 is locked.

[0035] It should be understood that there is a cooperation tolerance between the outer decorative plate 2 and the front shell 1, that is, there is a gap between the outer decorative plate 2 and the front shell 1, which does not affect the locking of the relative position of the outer decorative plate 2 and the front shell 1.

[0036] Referring to Figure 4 In an example embodiment, in the first direction, the second clamping piece 32 abuts against the second limiting portion 14.

[0037] Specifically, when the second clamping piece 32 abuts against the second limiting portion 14, as shown in Figure 4 At this time, a flathead screwdriver is inserted from top to bottom, so that the flathead screwdriver is inserted between the second clamping piece 32 and the second limiting portion 14, that is, the second clamping piece 32 can be pushed to move close to the outer decorative plate 2, so that the protruding portion 321 is separated from the second limiting portion 14, and the operation is more convenient and fast.

[0038] Referring to Figure 4 In an example embodiment, a first inclined surface is arranged on the side portion of the second clamping piece 32 away from the first limiting portion 13; wherein the side of the second clamping piece 32 facing the outer decorative plate 2 is a first wall surface, and the included angle between the first inclined surface and the first wall surface is an acute angle.

[0039] When the flathead screwdriver is inserted from top to bottom, the tip of the screwdriver contacts the side of the second locking member 32 away from the first limiting part 13, and is then guided by the first inclined surface, so that the tip of the screwdriver enters between the second locking member 32 and the second limiting part 14. This further improves the convenience of inserting the flathead screwdriver and separating the protrusion 321 from the second limiting part 14, thereby further improving work efficiency.

[0040] refer to Figure 7 In an exemplary embodiment, a second inclined surface is provided on the side of the protrusion 321 that is away from the second limiting part 14; wherein, the side of the protrusion 321 that is away from the second snap-fit ​​member 32 is a second wall surface, and the included angle between the second inclined surface and the second wall surface is an obtuse angle.

[0041] Specifically, during the process of connecting the outer trim panel 2 and the front shell 1, when the outer trim panel 2 is slid down, the second limiting part 14 first contacts the second inclined surface, and the second limiting part 14 further pushes the protrusion 321 closer to the outer trim panel 2 by relying on the second inclined surface, so that the second snap-fit ​​32 deforms; in this way, the second limiting part 14 and the second inclined surface cooperate to push and squeeze the protrusion 321, the process is smoother and the wear is less.

[0042] refer to Figures 3-5 In an exemplary embodiment, a third limiting groove 15 is provided on the side of the front shell 1 facing the outer trim panel 2. The third limiting groove 15 is located on the side of the first limiting groove 11 away from the second limiting groove 12. The outer trim cover connection structure may also include a third limiting part 16, a second snap-fit ​​plate 4, and a third snap-fit ​​member 41. The third limiting part 16 is disposed on the side wall of the third limiting groove 15 away from the first limiting groove 11 in a third direction and is located at the opening of the third limiting groove 15. The second snap-fit ​​plate 4 is disposed on the side of the outer trim panel 2 facing the front shell 1 and is located in the third limiting groove 15. The third snap-fit ​​member 41 is connected to the side of the second snap-fit ​​plate 4 away from the outer trim panel 2 and extends out of the side of the second snap-fit ​​plate 4. In a first direction, the third snap-fit ​​member 41 abuts against the third limiting part 16.

[0043] Specifically, such as Figure 5 As shown, when the outer trim panel 2 is connected to the front shell 1, the second snap-fit ​​plate 4 is located in the third limiting groove 15, and the third snap-fit ​​member 41 abuts against the third limiting part 16 in the first direction, so that the connection between the outer trim panel 2 and the front shell 1 in the first direction is more stable.

[0044] Among them, such as Figures 3-5As shown, the third limiting groove 15 is located on the side of the first limiting groove 11 away from the second limiting groove 12, in other words, the second clamping plate 4 is located below the first clamping plate 3, since a flathead screwdriver needs to be inserted from the edge of the front shell 1, the second clamping piece 32 is close to the edge of the front shell 1, when the second clamping plate 4 is added, even if the overall length of the outer trim panel 2 is longer, the outer trim panel 2 below can also be effectively prevented from being raised relative to the front shell 1; of course, the number of second clamping plates 4 can be multiple, and the specific number can be set according to the length of the outer trim panel 2, the longer the length of the outer trim panel 2, the more the number of second clamping plates 4, of course, the third limiting groove 15, the third limiting part 16 and the third clamping piece 41 matched with the second clamping plate 4 are increased synchronously, and each second clamping plate 4 can be arranged in the third direction.

[0045] Reference Figure 5 In an exemplary embodiment, in the second direction, both sides of the second clamping plate 4 are in contact with the side wall of the third limiting groove 15.

[0046] Specifically, in the second direction, both sides of the second clamping plate 4 are in contact with the side wall of the third limiting groove 15, so that near the second clamping plate 4, the outer trim panel 2 and the front shell 1 in the second direction cannot be loosened.

[0047] Further, if the width of the outer trim panel 2 is wider, the length of the first clamping plate 3 and / or the second clamping plate 4 in the second direction can be increased to ensure the stability of the connection between the outer trim panel 2 and the front shell 1.

[0048] Reference Figure 1 and Figure 2 In an exemplary embodiment, the side of the front shell 1 facing the outer trim panel 2 is also provided with a water guide groove 17; wherein the water guide groove 17 is located on the side of the first limiting groove 11 away from the second limiting groove 12 and communicates with the first limiting groove 11.

[0049] As Figure 2 shown, when using the outer trim cover connection structure, the second limiting groove 12 penetrates the side of the front shell 1, so in rainy weather, rainwater is easy to enter the first limiting groove 11 through the second limiting groove 12, after setting the water guide groove 17, the rainwater in the first limiting groove 11 will flow along the water guide groove 17, the side of the water guide groove 17 away from the first limiting groove 11 is close to the side of the front shell 1 in the second direction, so the rainwater will be guided by the water guide groove 17 to the side of the front shell 1, since there is a cooperation tolerance between the outer trim panel 2 and the front shell 1, that is, there is a gap, so the rainwater will eventually flow out of the water guide groove 17 and flow to the outside of the side of the front shell 1, thereby draining the water from the first limiting groove 11; in addition, the water guide groove 17 can have two and be oppositely arranged in the second direction, so that the water draining effect is better.

[0050] Reference Figure 9On the basis of the above-mentioned embodiments, the application further provides a charging device, which can be a charging pile. The charging pile comprises the outer cover connecting structure and the rear shell described above. The rear shell is connected to the side of the front shell 1 away from the outer cover 2.

[0051] Specifically, the front shell 1 is connected to the rear shell, and the front shell 1 and the rear shell can serve as the shell part of the charging device.

[0052] Reference Figure 9 In the example embodiments, the front shell 1 is provided with a through hole. The charging device can further comprise a display device 5 and a transparent window 6. The display device 5 is arranged between the front shell 1 and the rear shell and opposite the through hole in the first direction. The transparent window 6 is arranged in the through hole and abuts the edge of the through hole. The outer cover 2 is of a transparent structure.

[0053] It should be understood that the outer cover 2 is of a transparent structure, and the display device 5 is arranged between the front shell 1 and the rear shell and opposite the through hole in the first direction. Thus, the display content of the display device 5 can be conveyed to the side of the outer cover 2 away from the front shell 1.

[0054] The display device 5 can be a screen. Thus, the display content on the screen can be conveyed to the side of the outer cover 2 away from the front shell 1, and the display screen is effectively protected. Of course, the display device 5 can also be a two-dimensional code. Thus, it is convenient for the user to scan the code, and the two-dimensional code is protected. The display device 5, the through hole, and the transparent window 6 form a set of display structures. There can be multiple sets of display structures, which can be adjusted according to actual conditions.

[0055] Further, the area of the outer cover 2 opposite the transparent window 6 in the first direction is a transparent area. The remaining areas can be painted to improve the overall aesthetics of the outer cover 2. The front shell 1 and the transparent window 6 are fixed by induction welding, so that the front shell 1 and the transparent window 6 are completely sealed.

[0056] Reference Figure 9 In the example embodiments, the charging device can further comprise a waterproof ring 7. The waterproof ring 7 is arranged around the outer periphery of the transparent window 6 and located between the transparent window 6 and the outer cover 2. The waterproof ring 7 abuts the front shell 1 and the outer cover 2.

[0057] Specifically, the waterproof ring 7 can be a back-glued foamed foam. The waterproof ring 7 abuts the front shell 1 and the outer cover 2. Thus, even if the gap between the front shell 1 and the outer cover 2 is filled with rainwater and dust, the rainwater and dust will not flow to the transparent window 6. When a user observes the display device 5 from the side of the outer cover 2 away from the front shell 1, the display device 5 is clearly visible.

[0058] It should be understood that the waterproof ring 7 can also serve as part of the display structure.

[0059] The above merely preferred embodiments of the present application and are not intended to limit the patent scope of the present application, any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
