[0002] In the existing technology, the electrical control box of the ceiling machine serves as the mounting carrier for the core control components, and its interior usually contains the core circuit board used to control the operation of the entire machine.

[0003] However, the relevant technology has at least one of the following problems: In the existing technical solutions, the sealing performance of the electrical control box shell is poor, which can easily cause moisture from outside the shell to enter the electrical control box shell, thereby corroding the electronic components on the circuit board and reducing their service life. Utility Model Content

[0004] The technical problem solved by this application is that the sealing performance of the electrical control box shell in the existing technical solutions is poor, which makes it easy for moisture outside the shell to enter the electrical control box shell, thereby corroding the electronic components on the circuit board and reducing their service life.

[0005] To address the aforementioned issues, this application provides a ceiling-mounted control unit, comprising: an electrical control box body with an insertion hole on its side panel; a mounting plate, which is installed within the electrical control box body and has a tongue for engaging with the insertion hole; wherein the mounting plate is used to mount the circuit board assembly of the electrical control box; when the tongue engages with the insertion hole, the mounting plate and the tongue seal the insertion hole.

[0006] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution sets up a plug-in mating structure between the plug tongue and the socket, and achieves a seal in the socket during mating, effectively preventing moisture from entering the electrical control box through the socket, thereby improving the sealing effect of the electrical control box.

[0007] In one example of this application, the tongue includes an extension and a connecting portion; one end of the connecting portion is connected to the mounting plate, and the other end is connected to the extension, and the extension extends to the outer surface of the side plate through the insertion hole.

[0008] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution eliminates the gap around the insertion hole by directly fitting the extension part to the outer surface of the side plate. At the same time, the combined structure of the connecting part and the extension part automatically adjusts the contact pressure during the insertion process, without relying on additional sealing materials or complex assembly steps.

[0009] In one embodiment of this application, there are multiple side panels, including side panel one and side panel two disposed opposite to each other, and side panel three connected between side panel one and side panel two; either side panel one or side panel two is provided with an insertion hole; there are multiple mounting plates, including mounting plate one and mounting plate two; mounting plate one is connected between side panel one and side panel three; mounting plate two is disposed opposite to mounting plate one, and mounting plate two is connected between side panel two and side panel three.

[0010] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: by combining multiple side plates and double-board components, stable assembly of circuit board components can be achieved in a limited space. At the same time, by constructing a three-dimensional support network through symmetrically distributed board component one and board component two, the cost is reduced while fixing the circuit board.

[0011] In one embodiment of this application, board component one includes a first connecting portion one, a second connecting portion one, and a limiting portion one interconnected with each other; the first connecting portion one mates with a side plate one, and a tongue is formed in the first connecting portion one; the second connecting portion one mates with a side plate three, and the limiting portion one is connected to the side of the first connecting portion one away from the side plate three, and a first limiting slot for limiting the circuit board assembly is formed between the limiting portion one and the side plate three; and / or board component two includes a first connecting portion two, a second connecting portion two, and a limiting portion two interconnected with each other; the first connecting portion two mates with a side plate two, and a tongue is formed in the first connecting portion two; the second connecting portion two mates with a side plate three, and the limiting portion two is connected to the side of the first connecting portion two away from the side plate three, and a second limiting slot for limiting the circuit board assembly is formed between the limiting portion two and the side plate three.

[0012] Compared with the existing technology, the technical effect achieved by adopting this technical solution is that the plate and the side plate form a multi-faceted mating and fixing method, which makes the plate more stable during use. When installing the circuit board, you only need to insert the opposite sides of the circuit board into the first limiting slot and the second limiting slot respectively to complete the installation, which is convenient to operate.

[0013] In one example of this application, the inner side of the side panel is provided with a mounting groove for mounting a mounting plate; and / or the mounting plate is fixed to the side panel by a nailless riveting.

[0014] Compared with existing technologies, the technical effects achieved by this solution are as follows: the groove of the mounting slot protrudes outwards towards the electrical control box, allowing the mounting plate to be embedded in the inner wall of the side plate, thus avoiding increasing the volume of the electrical control box and reducing costs. At the same time, the mounting slot provides a positioning effect when installing the mounting plate, and the nail-free riveting process eliminates the need for rivets to fix the side plate to the mounting plate, reducing costs and improving installation efficiency.

[0015] In one example of this application, the bottom of the mounting groove is provided with a positioning hole; the mounting plate is provided with a positioning post that mates with the positioning hole.

[0016] Compared with existing technologies, the technical effect achieved by this technical solution is that the cooperation between the positioning pin and the positioning hole enables more efficient positioning and installation when installing mounting plates.

[0017] In one example of this application, a ceiling-mounted machine housing is provided, and an electrical control box is provided on the outside of the ceiling-mounted machine housing, with the electrical control box located on one side of the ceiling-mounted machine housing along its length; a junction box is connected to the electrical control box on the side away from the ceiling-mounted machine housing.

[0018] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By sequentially distributing the ceiling machine housing, electrical control box and junction box along the length axis, this application greatly reduces the width of the ceiling machine, enabling it to adapt more flexibly to narrow spaces, while also reducing costs.

[0019] In one embodiment of this application, the outside of the electrical control box is provided with a plug-in portion; the side of the junction box near the electrical control box is provided with a plug; the plug is inserted and connected to the plug-in portion.

[0020] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the junction box is fixed to the electrical control box by plugging it in, which makes installation and disassembly very convenient and improves the efficiency of disassembly and assembly.

[0021] In one embodiment of this application, the plug-in portion includes a plug-in buckle that covers the area enclosed by the plug hole; wherein, a limiting space for accommodating the plug tab and the plug tongue is formed between the plug-in buckle and the side plate, and the combination structure of the plug tongue and the plug tab forms an interference fit with the plug-in buckle.

[0022] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the combination structure of the tongue and the insert forms an interference fit with the snap fastener, making the tongue and the insert more stable under the interaction force, and further improving the tightness of the fit between the tongue and the side plate, thus improving the waterproof effect.

[0023] In one embodiment of this application, the insert and the tongue are stacked on top of each other within the limiting space; or the insert and the tongue are arranged side by side laterally within the limiting space.

[0024] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: This solution, by limiting the arrangement of the inserts and tongues, uses the physical barrier of interference fit to replace the traditional threaded connection, which not only eliminates the sealing defects caused by screw fixing, but also effectively prevents moisture from entering the electrical control box through the insertion hole, avoiding damage to the circuit board components due to moisture, but also ensures the assembly stability of the inserts and tongues, and extends the service life of the equipment.

[0025] By adopting the technical solution of this application, the following technical effects can be achieved: (1) This application achieves the fixing of the mounting plate by means of the plug-in mating structure of the plug tongue and the socket, and at the same time, the plug tongue and the mounting plate automatically seal the socket to form an effective physical barrier, thereby avoiding damage to the internal circuit board components due to moisture, and significantly improving the sealing reliability and service life of the product. (2) By setting a plug-in buckle, it forms an interference fit with the plug tongue and the plug plate of the junction box. This not only realizes the convenient disassembly and assembly of the junction box and the electrical control box, but also makes the plug tongue fit more tightly with the side plate, further enhancing the waterproof effect. (3) The mounting plates are fixed to the electrical control box by means of plug-in and nail-free riveting, and the guiding effect of the positioning posts and mounting grooves greatly improves the convenience and efficiency of assembly. In addition, the compact layout of the ceiling machine housing, electrical control box and junction box distributed along the length direction effectively reduces the width of the whole machine, making the product more flexible to adapt to various narrow installation spaces, while reducing manufacturing costs.

The tongue 111 and the mounting plate 11 completely seal the gap of the socket 104, preventing moisture from entering the electrical control box 1 through the socket 104.

[0033] Optionally, the tongue 111 is a boss structure. The mounting plate 11 is fixed by the tongue 111 and the side plate socket 104. The tongue 111 completely fills the internal space of the socket 104.

[0038] Optionally, the extension completely covers the opening area of ​​the socket 104 and is tightly fitted to the outer side wall of the side plate, forming a physical barrier to block the water vapor penetration path.

[0039] In one embodiment of this application, there are multiple side panels, including a first side panel 101 and a second side panel 102 disposed opposite to each other, and a third side panel 103 connected between the first side panel 101 and the second side panel 102; either the first side panel 101 or the second side panel 102 is provided with an insertion hole 104; there are multiple mounting plates 11, including a first mounting plate and a second mounting plate; the first mounting plate is connected between the first side panel 101 and the third side panel 103; the second mounting plate is disposed opposite to the first mounting plate, and the second mounting plate is connected between the second side panel 102 and the third side panel 103.

[0045] Specifically, the first connecting part 112 refers to the structural part of the plate that directly contacts the side plate 101 and forms a tongue 111; the second connecting part 113 refers to the extension part of the plate that connects to the side plate 3 103; the side of the second connecting part 113 fits against the inner side of the side plate 3 103 and is fixed by insertion through the insertion hole 104 and the slot structure; and the limiting part 114 refers to the protruding structure of the plate that is perpendicular to the first connecting part 112 and extends toward the side plate 2 102.

[0049] Furthermore, the circuit board assembly includes a circuit board and a sliding fitting.

[0050] In one example of this application, the inner side of the side panel is provided with a mounting groove 105 for mounting the mounting plate 11; and / or the mounting plate 11 is fixed to the side panel by nail-free riveting.

[0051] Specifically, the mounting slot 105 includes a first mounting slot for mounting plate one and a second mounting slot for mounting plate two; wherein, the first mounting slot is composed of a first mounting part and a second mounting part, the first mounting part is opened on side plate one 101 and is used to mount the first connecting part one 112; the second mounting part is opened on side plate three 103 and is used to mount the second connecting part one 113; the second mounting slot is composed of a third mounting part and a fourth mounting part, the third mounting part is opened on side plate two 102 and is used to mount the second connecting part one 113; the fourth mounting part is opened on side plate three 103 and is used to mount the second connecting part two.

[0053] Furthermore, the second connecting part 2 and the side plate 3 103 are riveted together and fixed by a nailless riveting part.

[0054] It should be noted that the principle of nail-free riveting is to apply high pressure to the side plate and mounting plate 11 using external pressure and mold, causing local deformation of the materials of both to form a mechanically interlocked connection point.

[0055] In one example of this application, the bottom of the mounting groove 105 is provided with a positioning hole 108; the mounting plate 11 is provided with a positioning post 115 that mates with the positioning hole 108.

[0058] Specifically, the mounting plate 11 is initially positioned by inserting the positioning pin 115 into the positioning hole 108 to ensure the relative positional accuracy between the mounting plate 11 and the side plate and to avoid gaps caused by misalignment. Subsequently, a nail-free riveting process is used to cause local deformation of the contact surface between the mounting plate 11 and the side plate, thereby achieving fixation.

[0059] In one example of this application, a ceiling-mounted machine housing 3 is provided with an electrical control box 1 on its outer side, and the electrical control box 1 is located on one side of the ceiling-mounted machine housing 3 along its length; a junction box 2 is connected to the side of the electrical control box 1 away from the ceiling-mounted machine housing 3.

[0060] It should be noted that one side of the ceiling machine housing 3 along its length is the shorter side of the ceiling machine.

[0061] In one embodiment of this application, the outside of the electrical control box 1 is provided with a plug-in portion; the junction box 2 is provided with a plug 201 on the side near the electrical control box 1; the plug 201 is plugged into the plug-in portion for connection.

[0062] Optionally, the plug-in part is a flexible plug-in buckle 106 structure, and both side plate 101 and side plate 202 are provided with plug-in parts. The junction box 2 is provided with inserts 201 on two opposite sides, which respectively form plug-in cooperation with the plug-in parts on side plate 101 and side plate 202.

[0063] In one embodiment of this application, the plug-in portion includes a plug-in buckle 106, which covers the area enclosed by the plug hole 104; wherein, a limiting space is formed between the plug-in buckle 106 and the side plate to accommodate the insert 201 and the tongue 111, and the combination structure of the tongue 111 and the insert 201 forms an interference fit with the plug-in buckle 106.

[0064] Specifically, the buckle 106 refers to the buckle structure covering the outside of the insertion hole 104. The insertion hole 104 at the upper end of side plate 101 is provided with the buckle 106 at the corresponding outer position. The insertion hole 104 at the upper end of side plate 2102 is provided with the buckle 106 at the corresponding outer position.

[0065] The limiting space refers to the cavity area formed by the inner wall of the snap-fit ​​106 and the outer surface of the side plate, which is used to constrain the installation position of the insert 201 and the tongue 111. This space ensures that the assembly trajectory of the insert 201 and the tongue 111 remains linearly aligned through geometric constraints.

[0066] Furthermore, the interference fit refers to the dimensional difference fit between the inner wall of the snap-fit ​​106 and the combined structure of the insert 201 and the tongue 111, which can be achieved by using a combination of elastic and rigid materials. This fit eliminates assembly gaps through the contact pressure generated by elastic deformation.

[0067] Specifically, within the limiting space formed by the snap-fit ​​106 and the side plate, the insert 201 and the tongue 111 are constrained in a fixed position for insertion, preventing sealing failure caused by assembly misalignment. When the insert 201 is inserted into the tongue 111, the overall size of the combined structure is slightly larger than the original size of the inner cavity of the snap-fit ​​106, causing the snap-fit ​​106 to undergo elastic deformation and continuously press against the surface of the combined structure, forming a gapless contact interface.

[0068] In one embodiment of this application, the insert 201 and the tongue 111 are stacked on top of each other within the limiting space; or the insert 201 and the tongue 111 are arranged side by side laterally within the limiting space.

[0069] Specifically, the stacked arrangement refers to the vertically stacked arrangement of the insert 201 and the tongue 111, which can be achieved by stacking them vertically. The interference fit between the snap fastener 106 and the side plate applies a clamping force to the stacked structure. The horizontally parallel arrangement refers to the horizontally parallel arrangement of the insert 201 and the tongue 111, which can be achieved by assembling them side by side. This increases the contact area and achieves uniform force distribution.

[0070] Specifically, the stacked arrangement forms multiple sealing interfaces through vertical overlap, utilizing the interference fit between the plug 106 and the side plate to generate continuous clamping force, ensuring a tight fit between the tongue 111 and the insert 201, blocking the path of moisture penetration. The horizontally arranged arrangement increases the contact area through lateral expansion, allowing the tongue 111 and insert 201 to be symmetrically distributed within the confined space, avoiding local gaps and providing balanced support for the circuit board assembly. Both arrangements optimize spatial layout, creating an interference fit physical barrier between the plug 106 and the combined structure, ensuring assembly stability while improving the sealing performance of the socket 104 area.
