[0060] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0061] Please refer to Figures 1 - 11 , in a first aspect, an embodiment of the present invention provides a sealing assembly adapted to seal the connection between a box body 100 and a box door 200, including: a first seal 1 disposed in the box body 100 and having a first position and a second position relative to the box body 100; a first driving mechanism 2 disposed in the box body 100 and adapted to drive the first seal 1 to act between the first position and the second position; wherein, a mating surface is formed at the connection between the inner wall surface of the box body 100 and the inner wall surface of the box door 200. When the first seal 1 is in the first position, the first seal 1 forms a sealing contact with the mating surface, and when the first seal 1 is in the second position, the first seal 1 releases the sealing contact with the mating surface.

[0062] In this embodiment, both the box body 100 and the box door 200 are made of anti-interference materials to prevent electronic signals from passing through. Electrical components are disposed in the box body 100. An opening is preferably provided on the front surface of the box body 100. The box door 200 is disposed at the opening and is rotatably connected to the box body 100. After the box door 200 is closed, the box door 200 closes the opening of the box body 100 to achieve the isolation between the inside and the outside of the box body 100. After the box door 200 is closed, the wall surfaces at the connection between the box body 100 and the box door 200 are perpendicular to each other and form a mating surface, and the gap between the box body 100 and the box door 200 is located on the mating surface.

[0063] A first seal 1 is arranged in the box body 100. When the box door 200 is closed, the first seal 1 is driven by the first driving mechanism 2 to move relative to the box body 100. The first seal 1 moves to the first position in the box body 100, and the first driving mechanism 2 stops moving. The first driving mechanism 2 serves as a supporting structure for the first seal 1, so that the first seal 1 is kept in the first position and is not easily separated from the box body 100 and the box door 200. The first seal 1 forms a sealed contact with the mating surface, and the first seal 1 is used to seal the gap between the box body 100 and the box door 200, so that external electronic signals are not easy to pass through the gap to interfere with the electrical components in the box body 100, thereby ensuring the normal use of the electrical components.

[0064] When the door 200 needs to be opened, the first driving mechanism 2 drives the first sealing member 1 to move to the second position away from the door 200, so as to facilitate the opening of the door 200 and subsequent operation of the electrical components in the box body 100 by the operator.

[0065] In the above embodiment, the first driving mechanism 2 is connected to the external communication by wired control or wireless control. When the first driving mechanism 2 is connected to the external communication by wireless control, after the box door 200 is closed, the operator can control the first driving mechanism 2 to start through the first controller outside the box body 100, so that the first driving mechanism 2 drives the first sealing member 1 to move to the first position, so as to close the gap between the box body 100 and the box door 200. When releasing the seal, the first driving mechanism 2 drives the first sealing member 1 to move to the second position, so as to release the seal of the gap by the first sealing member 1.

[0066] Alternatively, in addition to the above-mentioned wireless control, a control button may be provided on the outer wall of the box 100, and the control button and the first driving mechanism 2 are connected via a communication line. By starting the control button, the first driving mechanism 2 is started to drive the first sealing member 1 to move in the box 100.

[0067] In this embodiment, the first driving mechanism 2 is preferably an electric telescopic cylinder, and the telescopic end of the electric telescopic cylinder is arranged along the depth direction of the box body 100, that is, the movement direction of the telescopic end of the electric telescopic cylinder is perpendicular to the vertical direction of the box door 200, so as to drive the first sealing member 1 to move in the box body 100.

[0068] In this embodiment, refer to Figure 2 A hinge structure is provided between the box body 100 and the box door 200, and the box door 200 is rotatably connected to the box body 100 through the hinge structure.

[0069] Further, refer to Figure 1 , Figure 2 , Figure 8, an opening and closing mechanism 9 is provided between the box body 100 and the box door 200, and the opening and closing mechanism 9 is arranged outside the box body 100. The opening and closing mechanism 9 connects the box body 100 and the box door 200, and the opening and closing mechanism 9 is located outside the box body 100, so that the position and structure of the opening and closing mechanism 9 do not increase the gap at the connection between the box body 100 and the box door 200, improving the sealing effect of the first seal 1. And the opening and closing mechanism 9 can make the box door 200 move automatically, realizing the automatic opening and closing of the box door 200. In this way, by using the opening and closing mechanism 9, not only the opening and closing operations of the box door 200 are simple and convenient, but also the operator can be prevented from directly contacting the box body 100 when opening the box door 200, thus avoiding the risk of electric leakage and electric shock and improving the operation safety.

[0070] Specifically, referring to Figure 8 , the opening and closing mechanism 9 includes a support 901 fixed on the outer wall surface of the box body 100. A control shaft 902 is rotatably connected to the support 901. A control block 903 is sleeved and fixed on the control shaft 902. The side of the control block 903 is fixedly connected to one side of the box door 200. An installation piece 904 is fixed on the top of the box body 100, and a rotary driver 905 is fixed on the installation piece. The output end of the rotary driver 905 is connected to the control shaft 902. The rotary driver 905 is communicatively connected to a second controller. By controlling the rotary driver 905 to work through the second controller, the control shaft 902 and the control block 903 are driven to rotate relative to the box body 100, and the control block 903 drives the box door 200 to rotate relative to the box body 100, realizing the opening and closing of the box door 200 relative to the box body 100.

[0071] Optionally, referring to Figure 1 、 Figure 5 , a recess 3 is provided on the inner wall surface of the box door 200. The inner wall surface of the recess 3 and the inner wall surface of the box body 100 form a mating surface; when the first seal 1 is in the first position, at least part of the first seal 1 is located in the recess 3.

[0072] In this embodiment, the inner wall surface of the box door 200 is the wall surface of the box door 200 close to the box body 100, that is, the wall surface where the box door 200 and the box body 100 can form a mating surface. A recess 3 is provided on the inner wall surface of the box door 200, and the recess 3 is preferably a groove recessed from the surface of the box door 200. In this way, when the first seal 1 is in the first position, part of the structure of the first seal 1 can cross the gap at the connection between the box body 100 and the box door 200 and enter the recess 3, improving the sealing effect of the first seal 1.

[0073] In the above embodiments, the provision of the recess 3 provides a more stable sealing environment, enabling the first seal 1 to function better. Moreover, when the box body 100 and the box door 200 are slightly deformed due to temperature changes or other external forces, the first seal 1 within the recess 3 can still maintain a good contact pressure. At the same time, at least a part of the first seal 1 is located within the recess 3 and is restricted by the inner wall structure of the recess 3, making it difficult for the first seal 1 to shift or separate relative to the box door 200 due to vibration or other dynamic loads, further enhancing the sealing effect of the first seal 1, thereby maintaining the sealing effect at the connection between the box body 100 and the box door 200.

[0074] Optionally, the inner side wall of the recess 3 and the inner wall surface of the box body 100 are arranged coplanarly to form a continuously transitional mating surface; or, the inner side wall of the recess 3 and the inner wall surface of the box body 100 are arranged in a stepped and misaligned manner, and the inner side wall of the recess 3 extends radially and protrudes from the inner wall surface of the box body 100 to form a stepped transitional mating surface.

[0075] In this embodiment, referring to Figure 1 , taking the case where the inner side wall of the recess 3 and the inner wall surface of the box body 100 are arranged coplanarly as an example for illustration, the box body 100 includes a frame structure formed by connecting four side walls end to end. Plate bodies are respectively fixed to the front part and the rear part of the frame structure. The four side walls, the front plate body, and the rear plate ladder constitute the structure of the box body 100, and the box door 200 is arranged on the front plate body.

[0076] The inner wall surface of the box body 100 is the inner walls of the four side walls, and the inner side wall of the recess 3 is the side wall of the groove formed by the inward depression of the box door 200. The inner side wall of the recess 3 and the inner wall surface of the box body 100 are arranged coplanarly, and the inner walls of the four side walls and the side wall of the groove are on the same horizontal plane. In this way, the sealing structure of the first seal 1 adopts a regular flat plate structure. When the first seal 1 is in the first position, the flat plate structure fits on the inner walls of the four side walls and the side wall of the groove to achieve the sealing at the connection between the box body 100 and the box door 200.

[0077] Or, the inner side wall of the recess 3 and the inner wall surface of the box body 100 are arranged in a stepped and misaligned manner, that is, the side wall of the groove protrudes from the inner walls of the four side walls, so that the formed mating surface is a stepped structure. With this setting method, for the design of the sealing structure of the first seal 1, the sealing structure of the first seal 1 has a first fitting surface and a second fitting surface. When the first seal 1 is in the first position, the first fitting surface fits with the inner walls of the four side walls and the inner wall of the box door 200, and the second fitting surface fits with the side wall of the groove. In this way, the sealing effect of the first seal 1 on the connection between the box body 100 and the box door 200 can be further improved.

[0078] Optionally, referring to Figure 3 、 Figure 4, the first seal 1 includes: a movable frame 101 connected to at least part of the first driving mechanism 2; a sealing ring 102 connected to the movable frame 101, with one side of the sealing ring 102 facing the door 200 protruding from the movable frame 101. When the first seal 1 is in the first position, the sealing ring 102 is adapted to extend into the recess 3, and at least part of the outer edge surface of the sealing ring 102 is in contact with the inner side wall of the recess 3.

[0079] In this embodiment, the movable frame 101 is connected to the first driving mechanism 2. The movable frame 101 is driven by the first driving mechanism 2 to move within the box body 100, so as to drive the sealing ring 102 thereon to move, and the sealing ring 102 is used to seal the connection between the box body 100 and the door 200, thereby preventing external electronic signals from passing through. And when the first seal 1 is in the first position, part of the outer edge surface of the sealing ring 102 is in contact with the inner side wall of the recess 3, thereby expanding the contact area between the sealing ring 102 and the inner wall surface of the box body 100 and the wall surface of the door 200, and further improving the sealing effect of the sealing ring 102.

[0080] Preferably, referring to Figure 1 , Figure 4 , the door 200 is a plate structure in a rectangular shape, and the sealing ring 102 is adaptively arranged as a rectangular frame structure to seal the four gaps formed at the connection between the door 200 and the box body 100. Of course, if the door 200 is a plate structure with a non-rectangular shape, the specific structure of the sealing ring 102 can also be adaptively set according to the structure of the door 200.

[0081] Furthermore, referring to Figure 9 , a sliding groove 10 is provided on the inner wall of the box body 100, and the outer edge of the movable frame 101 is slidably adapted to the wall surface of the sliding groove 10. In this way, the movement direction of the movable frame 101 is restricted by the wall surface of the sliding groove 10, so that the gap between the sealing ring 102 and the connection between the box body 100 and the door 200 is aligned, and the sealing effect of the sealing ring 102 is improved.

[0082] Optionally, referring to Figure 1 , Figure 5 , Figure 6 , Figure 7, further including a locking member disposed between the cabinet door 200 and the first seal 1. The locking member includes: a mating portion 4 disposed on the first seal 1; a second driving mechanism 5 disposed on the cabinet door 200; and a locking portion 6 disposed on the cabinet door 200 and drivingly connected to the second driving mechanism 5. The locking portion 6 has a locking position and an unlocking position relative to the cabinet door 200. Wherein, the second driving mechanism 5 is adapted to drive the locking portion 6 to act, so that the locking portion 6 moves between the locking position and the unlocking position relative to the cabinet door 200. When the first seal 1 is in the first position and the locking portion 6 is in the locking position, the locking portion 6 is adapted to cooperate with the mating portion 4 to limit the movement of the first seal 1. When the locking portion 6 is in the unlocking position, the locking portion 6 is disengaged from the mating portion 4.

[0083] In this embodiment, after the cabinet door 200 is closed and the first seal 1 is in the first position to achieve sealing, the locking member is activated. The second driving mechanism 5 operates to drive the locking portion 6 to act, so that the locking portion 6 moves to the locking position. The mating portion 4 is limited by the locking portion 6, so that the mating portion 4 cannot move away from the cabinet door 200. When the cabinet door 200 needs to be opened, the second driving mechanism 5 operates to drive the locking portion 6 to act, so that the locking portion 6 moves to the unlocking position. Subsequently, the mating portion 4 can move away from the cabinet door 200 under the drive of the first driving mechanism 2. This setting further strengthens the first seal 1 on the one hand and improves the sealing effect. On the other hand, the locking member is used to strengthen the connection strength between the cabinet body 100 and the cabinet door 200, and prevent the cabinet door 200 from being opened when a non-opening instruction is received, which affects the normal operation of the electrical components.

[0084] Wherein, the mating portion 4 is a plurality of mating plates arranged around the movable frame 101 and / or the sealing ring 102. The second driving mechanism 5 is a driving device capable of controlling the movement of the locking portion 6 on the cabinet door 200. The locking portion 6 is a locking device 601 with a quantity and position matching the mating plates. When the first seal 1 is in the first position, the locking portion 6 is preferably located on the side of the mating portion 4 away from the cabinet door 200. By moving the locking portion 6 to the locking position, the movement of the mating portion 4 away from the cabinet door 200 is blocked.

[0085] In one implementation, the second driving mechanism 5 is a two-way or multi-way telescopic cylinder fixed on the inner wall of the cabinet door 200, and the locking portion 6 is a locking device 601 fixed on the telescopic end of the telescopic cylinder. The telescopic cylinder is connected to a control button on the outer wall of the cabinet door 200 through a communication line to control the telescopic cylinder to work and drive the locking device 601 to switch between the locking position and the unlocking position.

[0086] In another implementation, referring to, 5, Figure 6 , Figure 7The second driving mechanism 5 is a driver 501 fixed on the outer wall of the door 200 , and the output end of the driver 501 is connected to a driving gear 502 , which is rotatably connected to the inner wall of the door 200 .

[0087] The locking part 6 is a plurality of lockers 601 connected to the inner wall of the box door 200. There are six lockers 601, and the six lockers 601 are rotatably connected to the box door 200. Four lockers 601 are arranged in pairs and correspond to the two sides of the box door 200, and the remaining two lockers 601 correspond to the bottom and top of the box door 200. The sides of the four lockers 601 corresponding to the two sides of the box door 200 are fixedly connected with transmission cams 602, and the sides of the transmission cams 602 and the upper and lower groups of lockers 601 are fixed with sliding columns 603. The outer sleeve of the sliding column 603 is installed with a hollow drive frame 604, and the side of the hollow drive frame 604 is fixedly connected with a transmission rack 605. The sliding column 603 and the hollow drive frame 604 penetrate to form a sliding structure, and the hollow drive frame 604 is arranged in two groups in parallel. Transmission racks 605 are respectively provided on both sides of the driving gear 502 , and the two transmission racks 605 are meshed with the driving gear 502 .

[0088] In this way, the driver 501 works to drive the driving gear 502, and the driving gear 502 drives the two transmission racks 605 to move up and down respectively. The movement of the transmission rack 605 drives the hollow driving frame 604 to move. During the process of the hollow driving frame 604 moving up and down, the sliding column 603 runs through the inside thereof and slides and moves. The four transmission convex plates 602 and the lockers 601 corresponding to the side of the box door 200 can be controlled to rotate correspondingly through the sliding structure. The lockers 601 rotate and press on the side of the matching part 4, and the lockers 601 corresponding to the bottom and top sides of the box door 200 rotate respectively to press the corresponding matching parts 4. The lockers 601 corresponding to the bottom and top sides of the box door 200 are arranged to be inclined relative to the hollow driving frame 604 in the unlocked position to ensure the normal operation of the hollow driving frame 604. The locking member further strengthens the connection effect between the box door 200 and the box body 100, further improves the overall sealing, and prevents external electronic signals from interfering with the inside of the box body 100.

[0089] The electrical components in the electrical box need to be connected to external devices through cables. Usually, a cable hole is set on the wall surface of the frame enclosing the box 100. The cable is passed through the cable hole. The gap between the cable and the cable hole also affects the overall sealing effect of the electrical box. In addition, the cables in the existing box 100 are intricately distributed. When the long cables connected externally are subjected to tension, they are easily loosened from the electrical components connected to the box 100, which is not conducive to the normal operation of the electrical components.

[0090] Optionally, refer to Figure 9 ,Figure 10 , Figure 11 The sealing assembly also includes a second sealing member 7 arranged in the box body 100, and the second sealing member 7 includes: a sealing clamp 701, which is arranged in the box body 100 and coaxially arranged with the wire hole, and the sealing clamp 701 is formed by a pair of clamp arms, and one end of the pair of clamp arms is set as an opening and closing side that can be opened and closed relatively, and the cable is passed through the sealing clamp 701 and extends to the outside of the box body 100; an operating unit is connected to the sealing clamp 701, and is suitable for driving the opening and closing sides of the pair of clamp arms to open and close.

[0091] In this embodiment, the wire holes are arranged on the frame structure formed by connecting the four side walls of the box 100 end to end. The side walls of the box 100 are pierced with wire posts 11 to form wire holes. The sealing clamp 701 and the wire post 11 are located in corresponding positions. The sealing clamp 701 is composed of a pair of clamp arms. Under the action of the operating unit, one end of the sealing clamp 701 can be relatively opened and closed. That is, when one end of the sealing clamp 701 is opened, the sealing clamp 701 releases the restriction on the cable, so that the seal between the cable and the wire post 11 is released, and the cable can move relative to the wire post 11, which is convenient for the installation of the cable. When one end of the sealing clamp 701 is closed, the sealing clamp 701 seals the cable and the wire post 11, and limits the movement of the cable relative to the wire post 11, thereby improving the sealing effect of the box 100 and preventing the connection between the cable and the electrical component from loosening when the cable is subjected to external tension.

[0092] In one embodiment, referring to Figure 10 , Figure 11 The sealing clamp 701 is a structure with a sealing effect, that is, a sealing gasket 705 is arranged on the end surfaces of the two clamp arms close to each other. When the sealing clamp 701 clamps the cable, the sealing gasket 705 fits against the outer wall surface of the cable, thereby sealing the gap between the cable and the wire pole 11.

[0093] Optionally, refer to Figure 9 , the operating end of the operating unit is suitable for abutting against the first sealing member 1 ; and / or, the operating end of the operating unit is suitable for connecting with at least part of the first driving mechanism 2 .

[0094] In this embodiment, the operating end of the operating unit is a driving end that can drive the sealing clamp 701 to open and close. The operating end of the operating unit is against the first sealing member 1, so that when the first sealing member 1 moves from the first position to the second position, the first sealing member 1 drives the driving end to move, so that the sealing clamp 701 is opened to release the restriction on the cable. In this way, the opening of the box door 200 and the sealing clamp 701 are linked. After the box door 200 is opened, the sealing clamp 701 is in an open state, which is convenient for the operator to operate the cable and improves the work efficiency. Similarly, the operating unit can also be connected to the first driving mechanism 2 in a transmission manner, and the first driving mechanism 2 drives the operating end of the operating unit to move, so that the sealing clamp 701 is conveniently opened.

[0095] Optionally, refer to Figure 10 , Figure 11 The operating unit includes: a pair of connecting parts 702, which are respectively fixedly connected to a pair of clamping arms; a guide part 703, which is sleeved on the pair of connecting parts 702 and is suitable for limiting the movement of the pair of connecting parts 702 along the guide direction so that the opening and closing sides of the pair of clamping arms are relatively opened and closed; a transmission part 704, one end of which is connected to the guide part 703, and the other end of the transmission part 704 is the operating end of the operating unit.

[0096] In a specific embodiment, a pair of clamping arms are rotatably connected to the inner wall of the box body 100, the connecting portion 702 is a push rod fixedly connected to the clamping arms, the guiding portion 703 is a guide slide mounted on the pair of push rods, the transmission portion 704 is a slide rod fixed to the guide slide, the slide rod is arranged on the side of the guide slide away from the clamping arms, and the slide rod is linked to the movable frame 101 and / or the first driving mechanism 2. A pair of guide slides 706 are fixed on the inner wall of the box body 100, and the slide rods are passed through the guide slides 706 and are limited by the guide slides 706.

[0097] In this way, taking the linkage between the transmission part 704 and the movable frame 101 as an example, the movable frame 101 moves to make the transmission part 704 move in a direction away from the box door 200, and the transmission part 704 drives the guide part 703 to move, and a pair of connecting parts 702 in the guide part 703 approach each other, and the pair of connecting parts 702 act on the clamping arms respectively to realize the opening of the pair of clamping arms, so as to facilitate the separation of the sealing clamp 701 and the cable.

[0098] In the above embodiment, referring to Figure 9 When the transmission part 704 is configured to abut against the movable frame 101, in order to shorten the length of the transmission part 704 and facilitate linkage with the movable frame 101, a transverse plate 103 is fixedly connected to the end face of the movable frame 101 facing the transmission part 704, and the transverse plate 103 abuts against the transmission part 704.

[0099] Of course, in addition to the above-mentioned structure, the operating unit may also adopt other existing types of transmission mechanisms that can convert linear motion into separation motion to meet usage requirements.

[0100] Optionally, it further includes: an elastic member 8, which is arranged between the transmission part 704 and the box body 100, and the elastic member 8 is suitable for driving the transmission part 704 to move toward the box door 200, so that the pair of clamping arms are automatically kept in a closed state.

[0101] In this embodiment, refer to Figure 10 , Figure 11, an elastic member 8 is provided on the transmission part 704, and the elastic member 8 causes the transmission part 704 to have a tendency to move towards the direction close to the cabinet door 200. In this way, after the cabinet door 200 is closed and the first seal 1 moves to the first position, under the action of the elastic member 8, the transmission part 704 acts towards the cabinet door 200, and a pair of connecting parts 702 in the guiding part 703 move away from each other. By acting on the clamping arms respectively through the pair of connecting parts 702, a pair of clamping arms are closed, which facilitates the sealing of the connection between the cable and the terminal post 11 by the sealing clamp 701 and the clamping and fixing of the cable.

[0102] In a specific embodiment, referring to Figure 11 , the elastic member 8 includes a fixed ring 801, a movable ring 802 and a spring 803. The fixed ring 801 is located on the side of the movable ring 802 away from the cabinet door 200. The fixed ring 801 is fixed to the guiding sliding seat 706 close to the guiding part 703. The movable ring 802 is fixed to the transmission part 704. The spring 803 is sleeved on the transmission part 704 and is located between the fixed ring 801 and the movable ring 802. During the process of the first seal 1 moving from the first position to the second position, the movable ring 802 follows the transmission part 704 to move and compress the spring 803. During the process of the first seal 1 moving from the second position to the first position, the movable ring 802 drives the transmission part 704 to reset under the action of the spring 803.

[0103] Of course, in addition to adopting the above structural arrangement, the elastic member 8 can also adopt other structures that can realize the automatic reset of the transmission part 704.

[0104] In a second aspect, an embodiment of the present invention provides an electrical cabinet, including the above-mentioned sealing assembly. The sealing assembly includes a first seal 1 for sealing the connection between the cabinet body 100 and the cabinet door 200, and a second seal 7 for sealing the connection between the cable and the through-hole. Through the arrangement of the first seal 1 and the second seal 7, after the cabinet door 200 is closed, the sealing effect of the cabinet body 100 is effectively improved, and further the sealing effect of the electrical cabinet is improved, preventing external electronic signals from interfering with the electrical components in the electrical cabinet.
