In connection with fig. 3-6, the frame piece 11 can be understood as a frame flange, which has the relevant function of a flange, i.e. the frame piece 11 can be assembled with the box body 20 by means of the first fastening member 51 (shown in fig. 2). The material of the frame piece 11 may be PP plastic (polypropylene), nylon plastic or other high-strength plastic, and the frame piece 11 is manufactured by injection molding, that is, the hollow portion 111 and the peripheral portion 113 are integrally molded. The frame piece 11 has a through hole 1111 through which the plurality of sockets 122 are inserted so as to be inserted into and removed from the external terminals. The peripheral edge of the panel 121 is received by the sink 112 surrounding the through hole 1111, and the peripheral edge of the panel 121 is hermetically connected to the frame piece 11, so that the sealing and waterproof effects at the joint of the peripheral edge of the panel 121 and the frame piece 11 can be improved.

In other embodiments, the hollow portion 111 and the peripheral portion 113 may be integrally bonded by gluing, that is, after two annular members are stacked, the two annular members are fixed by potting. In the present embodiment, the material of the hollow portion 111 and the material of the peripheral portion 113 are the same, but in other embodiments, the material of the hollow portion and the material of the peripheral portion may be different.

In the present embodiment, the frame piece 11 is annular, and it is understood that the frame piece 11 has a geometric structure with an internal opening, but the outer shape is not limited thereto, for example, in the present embodiment, the frame piece 11 has a rectangular shape, and in other embodiments, the frame piece may have a circular shape.

In this embodiment, the panel 121 is a rectangular plate, and correspondingly, the sinking groove 112 is rectangular. The arrangement of the plurality of sockets 122 is rectangular, and correspondingly, the through holes 1111 are rectangular holes.

When the peripheral side surface 1211 is attached to the annular bottom wall 1121, and the peripheral end surface 1212 is attached to the annular side wall 1122, the sealing performance of the connection portion can be enhanced. In other embodiments, the peripheral side 1211 may be a curved surface, the annular bottom wall 1121 is a curved surface adapted to the curved surface, the peripheral end surface 1212 is a curved surface, and the annular side wall 1122 is a curved surface adapted to the curved surface. The curved surface can prolong the necessary path for the external liquid to flow in, and can improve the sealing effect to a certain extent. Similarly, the peripheral side 1211 may include two planes disposed at an angle, and the annular bottom wall 1121 is a matched plane disposed at an angle.

In this embodiment, referring to fig. 3 and 4, the panel assembly 10 further includes a first waterproof sealant 91, and the peripheral side 1211 and the annular bottom wall 1121 are glued together by the first waterproof sealant 91; and/or, the panel assembly 10 further includes a second waterproof sealant 92, and the peripheral end face 1212 is bonded to the annular side wall 1122 via the second waterproof sealant 92.

In other embodiments, the peripheral side 1211 and the annular bottom wall 1121 may be bonded together by a double-sided adhesive tape, and the peripheral end face 1212 and the annular side wall 1122 may also be bonded together by a double-sided adhesive tape.

In the present embodiment, referring to fig. 4, one side surface of the hollow portion 111 opposite to the peripheral portion 113 is protruded to form a stepped structure, so that a sink 112 is formed between the hollow portion 111 and the peripheral portion 113.

In this embodiment, the frame piece 11 is directly molded by injection molding to form a stepped structure as shown in fig. 4-6, i.e., the hollow portion 111 and the peripheral portion 113 are integrally molded by injection molding. It will be appreciated that this structure is similar to that, the center of a rectangular plate is punched first to separate the middle part and form the through hole 1111, and then the part surrounding the through hole 1111 is punched to recess the part and form the sink 112, so that a similar step structure can be formed.

It should be noted that co-planarity herein is not an absolute requirement to satisfy the definition in geometric terms of "co-planarity". Some deviation is allowed in the implementation. It will be appreciated that a potting process may be performed to enhance the sealing effect at a location where a surface of the peripheral portion 113 remote from the hollow portion 111 is aligned with a surface of the panel 121 remote from the receptacle 122. In other embodiments, the depth of the sinking groove 112 may be deeper, and the periphery of the panel 121 is completely embedded in the sinking groove 112, or the depth of the sinking groove 112 is shallower, and a surface of the panel 121 away from the socket 122 protrudes from a surface of the peripheral portion 113 away from the hollow portion 111.

Referring to fig. 7 and 9, six first internally threaded posts 213 are provided protruding from the bottom wall of the body 21 and configured to be assembled to the fuse circuit board 80 by fasteners (e.g., screws). Also protruding from the bottom wall of body 21 are two second internally threaded posts 214 configured to mount the contactor 70 with fasteners (e.g., screws). Wherein the first internally threaded post 213 has a height greater than the height of the second internally threaded post 214, i.e., the contact 70 is closer to the bottom wall of the body 21 than the fuse circuit board 80, and the fuse circuit board 80 is located above the contact 70. In such a way, the arrangement of the electrical components is more reasonable, the space in the box body 20 is fully utilized, and the overall structure of the fuse box 100 is more compact to a certain extent.

The mark panel 60 is attached to the outer side of the fixing piece 30, and the mark panel 60, the fixing piece 30, the sealing ring 40 and the frame piece 11 are locked by the first fastening piece 51, so that the sealing effect is further improved.

The extension holes 62 on the identification panel 60 facilitate the extension of the socket 122, so that the operation is more convenient in daily use, the operation is more convenient when the terminals are plugged and pulled out, and the socket panel 12 can be conveniently replaced when maintenance is needed.

Note that, glue may be poured into the gaps between the above-mentioned components to improve the sealing effect, for example, glue may be poured into the gaps between the frame piece 11 and the receptacle panel 12, between the frame piece 11 and the sealing ring 40, between the sealing ring 40 and the inner side of the fixing piece 30, and between the logo panel 60 and the outer side of the fixing piece 30 to further improve the sealing effect.

The fuse circuit board 80 and the contactor 70 are arranged in a manner that the volume of the fuse box 100 can be reduced to a certain extent, and the probability of water inflow can also be reduced to a certain extent due to the reduction of the volume. When the fuse box 100 is mounted on the unmanned equipment body, the occupied space can be reduced.

To sum up, the embodiment of the utility model provides a panel component 10, fuse box 100 and unmanned aerial vehicle, panel 121 periphery of socket panel 12 sets up in heavy groove 112 to, panel 121 and frame piece 11 sealing connection can improve the sealed effect of panel 121 and frame piece 11, and the through hole 1111 that possesses on the frame piece 11 can supply socket 122 to pass, be convenient for with the plug of external terminal. When the panel assembly 10 is mounted on the body 20 of the fuse box 100, the sealing and waterproof effects of the fuse box 100 can be improved significantly. Meanwhile, the unmanned equipment is provided with the fuse box 100, and also has better sealing and waterproof performance.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
