[0036] Please refer to Figure 1 , Figure 2 and Figure 6The present embodiment provides a flip mechanism, which includes a cover 10, a hinge 20, a box body 30, and a middle frame 40 connected to the box body 30; the hinge 20 includes a fixed portion 21 and a rotating portion 22, the fixed portion 21 is connected between the middle frame 40 and the box body 30, and the rotating portion 22 is rotatably connected to the cover 10, so that the cover 10 can rotate relative to the middle frame 40. The flip mechanism can realize at least a part of the hinge 20 to be hidden, thereby effectively protecting the hinge 20.

[0037] It should be noted that the flip mechanism of the present application includes a cover 10, a hinge 20, a box body 30 and a middle frame 40. Among them, the middle frame 40 is arranged on the box body 30, and the cover 10 is rotatably connected with the middle frame 40 or the box body 30 through the hinge 20, so that the cover 10 can rotate relative to the box body 30, so as to realize closing or opening the box body 30 through the cover 10.

[0038] The box body 30 may be a box body 30 of a distribution box, or may be a box body 30 of other structures, and the present application does not limit the specific type and use of the box body 30. In other words, the flip mechanism of the present application may be applied to a distribution box, or may be applied to other feasible structural components, and the present application does not specifically limit the application scenario of the flip mechanism.

[0039] The specific structure of the hinge 20 can refer to Figure 6 As shown, in the present embodiment, the hinge 20 includes a fixed portion 21 and a rotating portion 22, wherein the fixed portion 21 is used to be fixed to the box body 30 or the middle frame 40, and the rotating portion 22 is used to be rotatably connected to the surface cover 10. It should be noted that, in the present embodiment, the rotating portion 22 is stationary. When the surface cover 10 of the flip mechanism is opened and closed, the surface cover 10 is driven to rotate relative to the rotating portion 22 to realize the rotation of the surface cover 10 relative to the box body 30, thereby achieving the function of opening or closing the box body 30.

[0040] In this embodiment, the fixing portion 21 is connected between the middle frame 40 and the box body 30, so that the fixing portion 21 of the hinge 20 can be hidden and prevented from being exposed. The present application sets the fixing portion 21 between the middle frame 40 and the box body 30, so that at least the fixing portion 21 of the hinge 20 can be installed in a hidden manner, thereby effectively protecting the fixing portion 21.

[0041] It should be noted that, in order to completely hide the fixing portion 21 of the hinge 20 , the orthographic projection of the middle frame 40 on the fixing portion 21 of the hinge 20 should completely cover the fixing portion 21 of the hinge 20 .

[0042] To sum up, the flip mechanism provided in the present application includes a cover 10, a hinge 20, a box body 30 and a middle frame 40 connected to the box body 30; the hinge 20 includes a fixed part 21 and a rotating part 22, the fixed part 21 is connected between the middle frame 40 and the box body 30, and the rotating part 22 is rotatably connected to the cover 10 so that the cover 10 can rotate relative to the middle frame 40. The present application rotatably connects the rotating portion 22 of the hinge 20 with the cover 10, so that by driving the cover 10 to rotate relative to the rotating portion 22 of the hinge 20, the cover 10 can be flipped relative to the box body 30, thereby realizing the switching of the cover 10 and the box body 30 between the covering state or the closed state; by providing a middle frame 40, and connecting the fixed portion 21 of the hinge 20 between the middle frame 40 and the box body 30, the fixed portion 21 of the hinge 20 can be concealedly installed between the middle frame 40 and the box body 30 to avoid the fixed portion 21 of the hinge 20 being exposed. In this way, the flip mechanism can realize the concealed installation of at least part of the hinge 20, thereby effectively protecting the hinge 20 and beautifying the appearance of the flip mechanism.

[0043] Please refer to Figure 6 and Figure 7 Optionally, the hinge 20 also includes a connecting portion 23, which is connected between the fixed portion 21 and the rotating portion 22, and the rotating portion 22 includes a first body 221 and a rotating shaft 222 connected to the first body 221; the first body 221 is connected to the connecting portion 23, and the rotating shaft 222 is rotatably connected to the face cover 10.

[0044] It should be noted that the rotating shaft 222 is fixed to the first body 221 , and the rotating connection between the rotating shaft 222 and the surface cover 10 is only an example given in the present application, and is not a limitation on the specific structure of the hinge 20 of the present application.

[0045] The first body 221 and the rotating shaft 222 may be coaxially arranged, and the diameter of the first body 221 may be greater than the diameter of the rotating shaft 222, that is, the first body 221 and the rotating shaft 222 may be connected to each other to form a stepped shaft structure, such as Figure 6 As shown, the first body 221 of the stepped shaft structure can also play a certain role in limiting the surface cover 10, thereby preventing the surface cover 10 from falling off the rotating shaft 222.

[0046] In addition, in this embodiment, optionally, the orthographic projections of the rotating shaft 222 and the fixing portion 21 on the box body 30 are arranged at intervals. Figure 6 As shown, there is a certain distance between the rotating shaft 222 and the fixing portion 21, so that there is a gap between the cover 10 and the middle frame 40. In this way, when the cover 10 is opened, the opening angle of the cover 10 can be larger.

[0047] Please refer to Figure 2 , Figure 4 and Figure 6 As shown, optionally, the connecting portion 23 includes a first sub-portion 231 and a second sub-portion 232 connected to the first sub-portion 231 , the first sub-portion 231 is connected to the fixing portion 21 , and the second sub-portion 232 is connected to the first body 221 ; the first sub-portion 231 and the second sub-portion 232 are arranged at an angle.

[0048] It should be noted that the specific angle between the first sub-section 231 and the second sub-section 232 is not limited in this application, and those skilled in the art can set it as needed. For example, it can be greater than or equal to 90°. Of course, this angle range is only an example and is not a limitation of this application.

[0049] The first sub-portion 231 and the second sub-portion 232 are arranged at an angle, and the first sub-portion 231 and the fixing portion 21 may also be arranged at an angle, such as Figure 6 As shown, along the thickness direction (ie, the first direction a) of the middle frame 40, a height difference (eg, Figure 5 As shown), when the hinge 20 is installed, the fixing portion 21 can be hidden and installed between the middle frame 40 and the box body 30, and the rotating portion 22 is arranged on one side of the middle frame 40.

[0050] The first sub-portion 231 and the second sub-portion 232 are arranged at an angle, so that the rotating portion 22 and the fixing portion 21 can be pulled apart by the first sub-portion 231 and the second sub-portion 232 , which can help ensure the opening angle of the cover 10 .

[0051] In order to hide the fixing portion 21, the fixing portion 21 is disposed between the middle frame 40 and the box body 30. In a first feasible implementation, optionally, the fixing portion 21 is connected to a side of the middle frame 40 facing the box body 30.

[0052] That is to say, in this implementation, the fixing portion 21 is connected to the middle frame 40 and is located on a side of the middle frame 40 close to the box body 30 .

[0053] In this implementation, optionally, a side of the middle frame 40 facing the box body 30 may be recessed with a receiving cavity 41, and the fixing portion 21 is received in the receiving cavity 41. In this way, the fixing portion 21 can be received in the middle frame 40, and the fixing portion 21 can be prevented from occupying the space of the flip mechanism.

[0054] In a second feasible implementation manner, optionally, the fixing portion 21 is connected to a side of the box body 30 facing the middle frame 40 .

[0055] That is to say, in this implementation, the fixing portion 21 is connected to the box body 30 and is located on a side of the box body 30 close to the middle frame 40 .

[0056] Similarly, in order to accommodate the fixing portion 21 , in this implementation, optionally, a receiving cavity 41 may be recessed on a side of the middle frame 40 facing the box body 30 , and the fixing portion 21 may be accommodated in the receiving cavity 41 .

[0057] It should be noted that, whether the fixing portion 21 is connected to the box body 30 or the middle frame 40, Figures 2 to 5 Optionally, a first avoidance portion 42 communicating with the accommodating cavity 41 can be provided on the middle frame 40, and the first avoidance portion 42 is arranged to penetrate the middle frame 40 along a first direction a, and the first direction a is the thickness direction of the middle frame 40; the first avoidance portion 42 is used to make way for the first sub-portion 231.

[0058] The first avoidance portion 42 is communicated with the accommodating cavity 41. Figure 3 and Figure 4 The present application can make way for the first sub-portion 231 by providing the first avoiding portion 42 .

[0059] In addition, please refer to Figure 8 and Fig. 9 As shown, optionally, a second avoiding portion 13 is further provided on the surface cover 10 , and the second avoiding portion 13 is used to make way for the second sub-portion 232 .

[0060] By setting the first avoidance portion 42 and the second avoidance portion 13, the cover 10 can be opened at an angle greater than 180° (the included angle between the cover 10 and the middle frame 40 is greater than 180°). In addition, by setting the first avoidance portion 42 and the second avoidance portion 13, the cover 10 of the flip mechanism can be relatively flat when flipped open. Figure 8 shown.

[0061] In this embodiment, in order to make the opening angle of the cover 10 more suitable for user operation, optionally, when the cover 10 is opened, the angle between the cover 10 and the middle frame 40 can be less than or equal to 190°. In other words, the maximum angle of the cover 10 relative to the middle frame 40 when it is opened can be controlled within 190°. For example, the maximum angle between the cover 10 and the middle frame 40 can be 180°, 185° or 190°.

[0062] To facilitate the connection between the rotating shaft 222 and the cover 10, optionally, as Figure 7 As shown, a protruding structure 11 is disposed on the cover 10 , a first through hole 111 is disposed on the protruding structure 11 , and a rotating shaft 222 is rotatably connected in the first through hole 111 .

[0063] In addition, the cover 10 may also be provided with Figure 7The avoidance groove 12 is shown, and at least a portion of the first body 221 is received in the avoidance groove 12. By providing the avoidance groove 12, at least a portion of the first body 221 can be sunk, and the overall structure of the flip cover mechanism can be made flatter.

[0064] To make the flipping of the cover 10 more reliable, optionally, as Figure 1 As shown, the hinge 20 may include two hinges 20 , and the two hinges 20 are spaced apart along the rotation axis 222 of the cover 10 .

[0065] When a protruding structure 11 is disposed on the surface cover 10 , the two hinges 20 may be located at opposite ends of the protruding structure 11 and connected to the protruding structure 11 , respectively.

[0066] Another aspect of the present invention provides a distribution box, which includes a circuit breaker, a base, a power supply, and the above-mentioned flip cover mechanism, wherein the circuit breaker, the base, and the power supply are respectively arranged in a box body 30 of the flip cover mechanism.
