[0043] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0044] In this application, the word "exemplary" is used to mean "used as an example, illustration, or description". Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. In order to enable any technician in the field to implement and use the utility model, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the utility model can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the utility model with unnecessary details. Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0045] In the related art, taking the power box as an example, hinges are generally installed to realize the rotational connection between the cover and the main body, which requires installation holes to be set on the main body. When the power box is used outdoors, there is a risk of water ingress. In addition, the assembly hinges require multiple screws to fix, resulting in low assembly efficiency and inconvenient disassembly and assembly.

[0046] In view of at least one of the above technical problems existing in the prior art, an embodiment of the present application provides a new type of power supply box, wherein a first matching portion, a second matching portion, a second guide groove and a second opening are arranged on the second rotating connection portion, and in the first state, the first matching portion is clamped in the first guide groove through the first opening, and is rotationally matched with the first guide groove; in the second state, the first rotating connection portion is clamped in the second guide groove through the second opening, and is rotationally matched with the second matching portion, so in the present application, only the first connecting member and the second connecting member need to be relatively moved so that the first matching portion is clamped in the first guide groove or the first rotating connection portion is clamped in the second guide groove to realize the assembly of the first connecting member and the second connecting member, which is beneficial to improving the assembly efficiency of the power supply box. In addition, since the first rotating connection portion and the second rotating connection portion in the present application have a first state and a second state that cooperate with each other, and whether in the first state or the second state, the first body and the second body can rotate relative to each other, the user can select different matching states according to actual needs, thereby increasing the applicability of the power supply box.

[0047] For ease of understanding, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0048] See also Figures 1 to 3 as well as Figure 6The embodiment of the present application provides a power supply box 100, which includes a first connecting member 10 and a second connecting member 20, and the first connecting member 10 and the second connecting member 20 are configured to rotate relative to each other. Accordingly, the first connecting member 10 and the second connecting member 20 correspond to the box body and the cover body of the power supply box, respectively. For example, the first connecting member 10 can be the cover body of the power supply box, and the second connecting member 20 can be the box body of the power supply box. The box body is provided with a storage cavity inside, and the upper part of the box body is provided with an opening. The cover body can rotate relative to the box body to open or close the opening on the box body.

[0049] See also Figure 1 , Figure 2 and Figure 6 , Figure 1 This is a three-dimensional structural diagram of the power box in a closed state. Figure 2 This is a three-dimensional structural diagram of the power box in an open state. Figure 6 It is a partial cross-sectional view of the power box in a closed state. The first connecting member 10 includes a first main body 11 and at least one first rotating connecting portion 12 arranged on the first main body 11, and the first rotating connecting portion 12 is provided with a first guide groove 124 and a first opening 125 connected to the first guide groove 124. Exemplarily, the first main body 11 is generally square, and includes a top cover 111 and a flange 112 arranged on the side of the top cover 111 facing the second connecting member 20. Of course, in other embodiments of the present application, the first main body 11 can also be other structures, which are not limited here.

[0050] Specifically, the first rotating connection portion 12 is disposed close to an edge of one side of the first body 11 . For example, the first rotating connection portion 12 is disposed on a flange 112 of the first body 11 .

[0051] Specifically, the first rotating connection part 12 and the first main body 11 are an integrally formed structure. For example, the first rotating connection part 12 may be integrally formed on the flange 112 of the first main body 11. Further, the first rotating connection part 12 and the first main body 11 are an integrally extruded structure (such as aluminum profile extrusion molding). For another example, the first rotating connection part 12 and the first main body 11 are an integral profile. This structural arrangement is beneficial to improving the strength of the first connecting member 10 and avoiding punching holes in the first main body 11, which is beneficial to improving the waterproof performance of the power box 100. Of course, in other embodiments of the present application, the first rotating connection part 12 and the first main body 11 may be formed separately, and the first rotating connection part 12 may be fixed to the first main body 11 by bonding, snap-fitting, or threaded connection, which is not limited here.

[0052] Specifically, see Figure 2 and Figure 4, the first guide slot 124 is provided with a first mounting opening 126 at at least one end in the rotation axis direction F, the first mounting opening 126 is communicated with the first guide slot 124, and the first opening 125 extends to the first mounting opening 126 along the rotation axis direction; the first matching portion 221 is configured to be installed in the first guide slot 124 along the rotation axis direction F through the first mounting opening 126 and the first opening 125, and is snapped into the first guide slot 124. In this embodiment, the first mounting opening 126 is provided at at least one end in the rotation axis direction F of the first guide slot 124, and the first matching portion 221 is configured to be installed in the first guide slot 124 along the rotation axis direction F through the first mounting opening 126 and the first opening 125, and is snapped into the first guide slot 124, which is conducive to simplifying the structure of the first connecting member and further improving the assembly efficiency of the power supply box.

[0053] In the present application, the second connecting member 20 includes a second main body 21 and at least one second rotating connecting portion 22 disposed on the second main body 21. Figure 1 , Figure 2 and Figure 6 The second body 21 is generally a square frame structure. The second body 21 includes a bottom plate 211 and a pair of side plates 212 arranged on the bottom plate 211. The side plates 212 are arranged at an angle with the bottom plate 211 (exemplarily, each side plate 212 is arranged perpendicular to the bottom plate 211), and extend along the length direction of the bottom plate 211 (that is, the rotation axis direction F of the power supply box 100). The pair of side plates 212 are arranged at intervals along the width direction of the bottom plate 211. The second rotating connection part 22 is arranged on a side plate 212 close to the first rotating connection part 12, and is located at an end of the side plate 212 away from the bottom plate 211. In this embodiment, by arranging the second rotating connection part 22 at an end of the side plate 212 away from the bottom plate 211, there is an avoidance gap between the second rotating connection part 22 and the bottom plate 211, which is conducive to avoiding interference between the first connecting member 10 and the second connecting member 20 during the rotation process.

[0054] Specifically, the second rotating connection part 22, the bottom plate 211 and the side plate 212 are an integrally formed structure. Further, the second rotating connection part 22, the bottom plate 211 and the side plate 212 are an integrally extruded structure (such as aluminum profile extrusion molding). For another example, the second rotating connection part 22, the bottom plate 211 and the side plate 212 are an integral profile. This structural setting is conducive to improving the strength of the second connecting member 20 and avoiding punching holes on the second main body 21, which is conducive to further improving the waterproof performance of the power box 100. Of course, in other embodiments of the present application, the second rotating connection part 22 and the second main body 21 can also be formed separately, and the second rotating connection part 22 can be fixed to the second main body 21 by bonding, clamping, or threaded connection, etc., which is not limited here.

[0055] In this application, please see Figure 4 and Figure 6 , the second rotating connection part 22 includes a first matching part 221 and a second matching part 222 that are arranged opposite to each other, and a second guide groove 224 and a second opening 225 that is connected to the second guide groove 224 are provided between the first matching part 221 and the second matching part 222. Specifically, the cross section of the second rotating connection part 22 (the cross section perpendicular to the rotation axis direction F) is generally in the shape of the letter "C", the first matching part 221 and the second matching part 222 correspond to the two ends of the second rotating connection part 22 respectively, and a second opening 225 is formed between the ends of the first matching part 221 and the second matching part 222 that are close to each other, and the first matching part 221 and the second matching part 222 enclose and form the second guide groove 224.

[0056] Specifically, a second mounting port 226 is provided at at least one end of the second guide groove 224 in the rotation axis direction F, the second mounting port 226 is connected to the second guide groove 224, and the second opening 225 extends to the second mounting port 226 along the rotation axis direction; the first rotating connection part 12 is configured to be clamped in the second guide groove 224 through the second mounting port 226 and the second opening 225.

[0057] For example, Figure 4 , Figure 6 and Figure 7As shown, when the first connecting member 10 and the second connecting member 20 are assembled, the side of the first connecting member 10 provided with the first rotating connecting portion 12 can be located above the second rotating connecting portion 22, and the first matching portion 221 is aligned with the first installation port 126 and the first opening 125, the inner arc portion 121 of the first rotating connecting portion 21 is aligned with the second installation port 226, and the second connecting portion 123 of the first rotating connecting portion 21 is aligned with the second opening 225, and then the first connecting member 10 and the second connecting member 20 are driven along the rotation axis direction F to move in a direction approaching each other so that the first matching portion 221 is engaged in the first guide groove 124. At this time, there is a gap between the first rotating connecting portion 12 and the second matching portion 222, that is, the first rotating connecting portion 12 is not rotationally matched with the second matching portion 222, and accordingly, the first rotating connecting portion 12 and the second rotating connecting portion 22 are in the first state. Of course, in some other embodiments of the present application, the first rotating connection portion 12 can also be aligned with the second mounting opening 226, for example, the outer wall surface of the inner arc portion 121 (that is, the side facing the outer arc portion 122) is close to and substantially parallel to the inner wall surface of the first matching portion 221 (the side facing the second matching portion 222), and the outer wall surface of the outer arc portion 122 (that is, the side away from the inner arc portion 121) is close to and substantially parallel to the inner wall surface of the second matching portion 222 (the side facing the first matching portion 221), and then the first connecting member 10 and the second connecting member 20 are driven along the rotation axis direction F to move in a direction close to each other so that the first rotating connection portion 12 is engaged in the second guide groove 224 (such as Fig. 9 As shown in the figure, the first rotating connection part 12 and the second rotating connection part 22 are in the second state accordingly. In the above manner, the first rotating connection part 12 and the second rotating connection part 22 are detachably connected along the rotation axis direction F. Similarly, the first rotating connection part 12 and the second rotating connection part 22 can be disassembled by pulling the first matching part 221 out of the first guide groove 124 along the rotation axis direction F or pulling the first rotating connection part 12 out of the second guide groove 224 along the rotation axis direction, which will not be described in detail here.

[0058] In the present application, the first rotating connection part 12 and the second rotating connection part 22 have a first state and a second state that cooperate with each other. In the first state, Figure 1 , Figure 2 and Figure 6 As shown, the first matching portion 221 is clamped in the first guide groove 124 through the first opening 125 and is rotatably matched with the first guide groove 124, that is, the portion of the first matching portion 221 inserted into the first guide groove 124 is clamped in the first guide groove 124 and can rotate relative to the wall surface of the first guide groove 124 to extend into or retract from the first guide groove 124. Specifically, as Figure 6 to Figure 7As shown, when the free end of the first body 11 rotates toward the free end away from the second body 21 (that is, the first body 11 rotates toward the direction of opening the power box), the first matching portion 221 gradually retracts from the first guide groove 124 until it is completely separated from the first guide groove 124. When the free end of the first body 11 rotates toward the free end close to the second body 21 (that is, the first body 11 rotates toward the direction of closing the power box), the first matching portion 221 gradually extends into the first guide groove 124. Further, when the free end of the first body 11 abuts against the free end of the second body 21, the end of the first matching portion 221 (that is, the end close to the second matching portion 222) approaches or abuts against the first connecting portion 123 (detailed description below). It can be understood that when the first rotating connection part 12 and the second rotating connection part 22 are in the first state, the first body 11 can rotate relative to the second body 21 within a certain angle range (for example, 0° to 90°), and the angle range within which the first body 11 can rotate relative to the second body 21 can be changed by changing the matching stroke of the first matching part 221 and the first guide groove 124. In this application, in the second state, please refer to Figure 3 and Fig. 9 , the first rotating connection part 12 is clamped in the second guide groove 224 through the second opening 225, and is rotationally matched with the second matching part 222. Specifically, when the first body 11 rotates to a larger angle (for example, greater than 90 degrees) relative to the second body 21, the first rotating connection part 12 and the second rotating connection part 22 are switched from the first state to the second state. At this time, if the free end of the first body 11 is continued to be driven to rotate toward the free end away from the second body 21, the first rotating connection part 12 (for example, the outer arc part 122) gradually extends into the second guide groove 224 through the second opening 225, and is rotationally matched with the inner side surface of the second matching part 222 (the side facing the first matching part 221). Similarly, when the first rotating connection part 12 and the second rotating connection part 22 are in the second state, if the free end of the first main body 11 is driven to rotate toward the free end close to the second main body 21, the first rotating connection part 12 (for example, the outer arc part 122) gradually retracts out of the second guide groove 224 through the second opening 225, and at the same time, the first matching part 221 moves in the direction close to the first guide groove 124. When the free end of the first main body 11 is driven to rotate toward the free end close to the second main body 21 to a preset angle (for example, 90 degrees), at this time, the first rotating connection part 12 (for example, the outer arc part 122) is about to be completely retracted out of the second guide groove 224 through the second opening 225 (that is, only the end of the outer arc part 122 close to the second connection part 223 cooperates with the part of the second matching part 222 close to the second opening 225), and the end of the first matching part 221 is inserted into the first guide groove 124 through the first opening 125 and rotates and cooperates with the first guide groove 124.

[0059] For example, in order to improve the stability of the power box 100 during operation, the first state and the second state can be when the rotation angle of the free end of the first body 11 is less than or equal to 75°, such as Figure 7 As shown, the first rotating connection part 12 and the second rotating connection part are in the first state; when the rotation angle of the free end of the first body 11 is between 75° and 105°, as shown in FIG. Figure 8 As shown, the first rotating connection part 12 and the second rotating connection part are in the first state and the second state at the same time, so that the contact area between the first rotating connection part 12 and the second rotating connection part is increased, which is beneficial to improve the stability of the first rotating connection part 12 and the second rotating connection part switching between the first state and the second state; when the rotation angle of the free end of the first body 11 is greater than or equal to 105°, as Fig. 9 As shown, the first rotating connection part 12 and the second rotating connection part are in the second state.

[0060] In summary, in the present application, the first rotating connection part 12 and the second rotating connection part are detachably connected along the rotation axis direction F thereof, and have a first state and a second state that cooperate with each other; in the first state, the first matching part 221 is clamped in the first guide groove 124 through the first opening 125, and is rotationally matched with the first guide groove 124; in the second state, the first rotating connection part 12 is clamped in the second guide groove 224 through the second opening 225, and is rotationally matched with the second matching part 222, so that the power box 100 in the present application only needs to drive the first connecting member 10 and the second connecting member 20 to move relative to each other so that the first matching part 221 is clamped in the first guide groove 124 or the first rotating connection part 12 is clamped in the second guide groove 224, so as to realize the assembly of the first connecting member 10 and the second connecting member 20, which is beneficial to improve the assembly efficiency of the power box 100. In some embodiments of the present application, please continue to refer to Figure 6 and Figure 7, the first rotating connection part 12 includes an inner arc part 121, an outer arc part 122 and a first connection part 123 connecting the inner arc part 121 and the outer arc part 122, the inner arc part 121 and the outer arc part 122 are arranged in concentric circles, the inner arc part 121, the outer arc part 122 and the first connection part 123 enclose the first guide groove 124; the end of the outer arc part 122 away from the first connection part 123 is connected to the first main body 11. It should be noted that the inner arc part 121 and the outer arc part 122 are arranged in concentric circles, which means that the inner arc part 121 and the outer arc part 122 have a common center on the same cross section, but different radii. Specifically in this application, the radius of the outer arc part 122 is greater than the radius of the inner arc part 121. The specific sizes of the inner arc part 121 and the outer arc part 122 are not limited here.

[0061] It can be understood that in the first state, when the free end of the first body 11 rotates in the direction away from the free end of the second body 21 under the driving action of an external force, the first matching portion 221 clamped in the first guide groove 124 moves along the first guide groove 124 toward the direction close to the first opening 125. During this process, the inner arc portion 121 and the outer arc portion 122 are respectively restrained and limited by the two opposite surfaces of the first matching portion 221, thereby preventing the first connecting member 10 and the second connecting member 20 from disengaging from each other during rotation.

[0062] This embodiment provides an inner arc portion 121, an outer arc portion 122 and a first connection portion 123 in the first rotation connection portion 12, and the inner arc portion 121, the outer arc portion 122 and the first connection portion 123 enclose the first guide groove 124, so that the structure of the first rotation connection portion 12 is more compact. In addition, the side of the outer arc portion 122 away from the inner arc portion 121 is used for rotational cooperation with the second matching portion 222, that is, in the second state, the arc surface of the side of the outer arc portion 122 away from the inner arc portion 121 is rotationally cooperated with the arc surface inside the second matching portion 222, which is conducive to further simplifying the structure of the power supply box 100 and improving the compactness of the structure of the power supply box 100.

[0063] Specifically, the first connection portion 123 is generally in a planar structure and is generally arranged in parallel with the first body 11 (the top cover 111 of the first body 11). The first connection portion 123 is arranged opposite to the first opening 125, and is respectively connected to one end of the inner arc portion 121 and the outer arc portion 122 away from the first opening 125. This structural arrangement is conducive to improving the structural compactness of the first rotating connection portion 12.

[0064] Specifically, the outer arc portion 122 is an arc plate and extends along the rotation axis direction of the power supply box 100. The outer arc portion 122 is convexly arranged on the outer side of the flange 112 of the top cover 111, and one end is connected to the flange 112 of the top cover 111, the central angle corresponding to the outer arc portion 122 is close to 90°, and the other end of the outer arc portion 122 is connected to the first connection portion 123.

[0065] Specifically, the inner arc portion 121 is generally in the shape of an arc plate, a round tube or a round rod, and extends along the rotation axis direction of the power box 100.

[0069] This embodiment arranges a second connection part 223 in the second rotating connection part 22, and the second connection part 223 is recessed in a direction away from the second opening 225, thereby avoiding interference between the first rotating connection part 12 and the second rotating connection part 22 when rotating in the second guide groove 224, which is beneficial to improving the stability of the power box 100.

[0070] In some embodiments of the present application, the second mating portion 222 is an arc plate, and the second mating portion 222 and the first mating portion 221 are arranged in concentric circles. Specifically, the first mating portion 221, the second mating portion 222, the inner arc portion (121) and the outer arc portion (122) are arranged in concentric circles. In this embodiment, by setting the second mating portion 222 as an arc plate, and the second mating portion 222, the first mating portion 221, the inner arc portion (121) and the outer arc portion (122) are arranged in concentric circles, so that when the power box in the present application is in the second state, the inner arc portion 121 can be held against the first mating portion 221 for limiting position, and the outer arc portion 122 can be held against the second mating portion 222 for limiting position, thereby preventing the first connecting member 10 and the second connecting member 20 from disengaging from each other during the rotation process, which is conducive to further improving the structural stability and compactness of the power box 100.

[0071] In some embodiments of the present application, the second matching portion 222 is an arc plate, and one end of the second matching portion 222 close to the second opening 225 is connected to the second body 21.
