[0017] The beneficial technical effects of the present invention are as follows

[0018] (1) The electric intelligent external frame waterproof structure in the present invention has a control system comprising two parts, which are respectively arranged in a main box and a junction box. The cable extending into the main box first extends into the junction box and then extends into the main box. The junction box can effectively prevent moisture from extending into the main box along the cable, improve the waterproof performance of the main box, and enhance the reliability of the electronic components in the main box. At the same time, all cables are concentrated in the junction box, and the centralized wiring layout can simplify the troubleshooting process and improve maintenance efficiency. At the same time, the main box and the junction box are connected by plugging and moving the block and the slide. The plug-in active connection method can be quickly connected and disconnected, which is convenient for the installation, maintenance and replacement of the main box and the junction box, and increases the flexibility of the system. In addition, the cable passes through the first partition cavity when extending into the junction box. The first partition cavity can effectively isolate the moisture entering the junction box along the cable, and prevent the moisture from affecting the junction box or even the electronic components inside the main box. The first partition cavity is also filled with sealant, which further improves the waterproof performance of the first partition cavity while fixing the position of the cable, especially the position of the cable skin. Reduce the displacement between the cable skin and the cable core to avoid potential safety hazards caused by exposed cable core.

[0019] (2) Furthermore, a limit slot is provided in the slide slot. When the main box is plugged into the junction box through the block, the positioning pin passes through the main box and extends into the limit slot. The positioning pin ensures the position between the main box and the junction box, so that the main box and the junction box reach the same position after each assembly, simplifying the assembly. At the same time, the positioning pin can effectively prevent the main box and the junction box from loosening due to vibration or impact during use, thereby improving the stability and safety of the equipment.

[0020] (3) Furthermore, a second groove is provided in the limiting boss, and the second groove is connected to the inner cavity of the main box. The second groove expands the space inside the main box. At the same time, the second wiring board in the main box is placed in the second groove, and the cable inserted into the main box is first inserted into the second groove. Even if moisture penetrates into the main box along the cable, the moisture will stay in the second groove, giving the operator enough reaction time to deal with the water ingress, thereby further improving the waterproof performance of the main box.

[0030] In order to make the purpose, technical scheme and advantages of the present invention clearer, the device proposed by the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings adopt a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, please refer to the accompanying drawings. It should be noted that the structure, proportion, size, etc. illustrated by the accompanying drawings of this specification are only used to match the content disclosed in the specification, so that people familiar with this technology can understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they do not have technical substantive significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effect that the present invention can produce and the purpose that can be achieved, should still fall within the scope of the technical content disclosed by the present invention.

[0031] Figure 1 A schematic diagram of the main structure of the electric intelligent external frame waterproof structure of the present invention is shown. Figure 2 The three-dimensional structural schematic diagram of the main box in the electric intelligent external frame waterproof structure of the present invention is shown in the upward direction.

[0032] Figure 3 The three-dimensional structural diagram of the junction box in the electric intelligent external frame waterproof structure of the present invention is shown. Figure 4 The figure shows the internal structure of the junction box in the electric intelligent external frame waterproof structure of the present invention. Figure 1 , Figure 2 , Figure 3 and Figure 4 The electric intelligent external frame waterproof structure includes a main box 1, a junction box 3 and an external frame body 4. The control system includes two parts, which are respectively arranged in the main box 1 and the junction box 3. The main box 1 is provided with a main board 11 and a power supply 12, and the power supply 12 is arranged below the main board 11. Because the mass of the power supply 12 is much greater than that of the main board 11, the power supply 12 is arranged below and supported by the inner wall of the main box 1, and extends into a structure specifically supporting the power supply 12. At the same time, the main board 11 is arranged above, which is also convenient for the operator to directly operate the main board 11 through buttons. In addition, the cable 6 extending into the main box 1 first extends into the junction box 3 and then into the main box 1. The junction box 3 can effectively prevent moisture from extending into the main box 1 along the cable 6, improve the waterproof performance of the main box 1, and enhance the reliability of the electronic components in the main box 1. At the same time, all cables 6 are concentrated in the junction box 3, and the centralized wiring layout can simplify the troubleshooting process and improve the maintenance efficiency. The lower surface of the main box 1 is raised to form two clamping bosses 13. A clamping block 131 is arranged on the clamping boss 13. The two card blocks 131 are arranged facing each other. The junction box 3 is arranged on the outer frame body 4. Two slide grooves 322 are provided on the junction box 3. The junction box 3 is connected to the main box 1 through the plug-in activity of the slide groove 322 and the card block 131. The plug-in activity connection mode can be quickly connected and disconnected, which is convenient for the installation, maintenance and replacement of the main box 1 and the junction box 3, and increases the flexibility of the system.

[0033] Among them, a first baffle 325 is also provided in the junction box 3, and a wire hole 327 is provided on the first baffle 325 for the cable 6 to pass through. The first baffle 325 and the inner wall of the junction box 3 surround to form a first partition cavity 326. The cable 6 extending into the junction box 3 passes through the first partition cavity 326. The first partition cavity 326 can effectively isolate the moisture entering the junction box 3 along the cable 6, and prevent the moisture from affecting the junction box 3 or even the electronic components inside the host box 1. The first partition cavity 326 is filled with sealant, and the filled sealant further improves the waterproof performance of the first partition cavity 326, and also fixes the position of the cable 6, especially the position of the skin of the cable 6. Reduce the displacement between the skin of the cable 6 and the core of the cable 6, and avoid the safety hazard caused by the exposed core of the cable 6.

[0034] Preferably, a limiting groove 323 is provided in the slide groove 322. A limiting hole 133 is provided on the clamping boss 13 and a positioning pin 2 is provided. The positioning pin 2 extends into the limiting groove 323 along the limiting hole 133. When the main box 1 is plugged into the junction box 3 through the clamping block 131, the positioning pin 2 passes through the main box 1 and extends into the limiting groove 323. The positioning pin 2 ensures the position between the main box 1 and the junction box 3, so that the main box 1 and the junction box 3 reach the same position after each assembly, thereby simplifying the assembly. At the same time, the positioning pin 2 can effectively prevent the main box 1 and the junction box 3 from loosening due to vibration or impact during use, thereby improving the stability and safety of the device.

[0035] In this embodiment, the positioning pin 2 is also provided with a circumferentially protruding shoulder 21. After the positioning pin 2 is installed, the shoulder 21 is located between the clamping boss 13 and the junction box 3. The positioning pin 2 is fixed to the main box 1 by the interference limit between the shoulder 21 and the clamping boss 13.

[0036] Figure 5 The schematic diagram of the internal structure of the main unit and the waterproof structure of the electric intelligent external frame of the present invention is shown. Figure 1 , Figure 2 and Figure 5 , a first groove 132 is provided on the inner side of the clamping boss 13. The first groove 132 is connected to the inner cavity of the main box 1. The first groove 132 expands the internal space of the main box 1. At the same time, the first groove 132 is located between the power supply 12 and the inner wall of the main box 1, thereby enhancing the air flow between the power supply 12 and the main box 1. The first groove 132 enhances the heat dissipation of the power supply 12 and reduces the temperature of the outer surface of the main box 1.

[0037] In this embodiment, a limiting boss 14 is also provided on the main box 1. The limiting boss 14 is provided between adjacent clamping bosses 13. After the junction box 3 is connected to the main box 1 through the plugging activity of the slide groove 322 and the clamping block 131, the junction box 3 contacts the clamping boss 13. While the position between the main box 1 and the junction box 3 is quickly positioned by the limiting boss 14, the limiting boss 14 contacts and supports the junction box 3, thereby increasing the contact area between the main box 1 and the junction box 3, and thus enhancing the stability of the connection between the main box 1 and the junction box 3.

[0038] Preferably, a second groove 141 is provided on the inner side of the limiting boss 14. The second groove 141 is connected to the inner cavity of the main box 1. A second wiring board 142 is arranged in the second groove 141. The second groove 141 expands the space inside the main box 1. At the same time, the second wiring board 142 in the main box 1 is placed in the second groove 141, and the cable 6 extending into the main box 1 is first extended into the second groove 141. Even if moisture penetrates into the main box 1 along the cable 6, the moisture will stay in the second groove 141, giving the operator enough reaction time to deal with the water ingress, thereby further improving the waterproof performance of the main box 1.

[0039] More preferably, the surface of the main box 1 surrounded by the limiting boss 14 and the clamping boss 13 is provided with a flat surface 15, that is, the junction box 3 contacts the flat surface 15 of the main box 1. The flat surface 15 increases the contact area between the junction box 3 and the main box 1, thereby enhancing the stability of the connection between the junction box 3 and the main box 1.

[0040] Figure 6 The vertical cross-sectional structure diagram of the main box and the junction box in the electric intelligent external frame waterproof structure of the present invention is shown. Figure 1 , Figure 3 , Figure 4 and Figure 6 The junction box 3 includes a cover plate 31 and a base 32. A slide groove 322 is provided on the base 32. The cable 6 passes through the base 32 and extends into the junction box 3. The junction box 3 is split into two parts, which is convenient for opening the junction box 3 to assemble and maintain the internal structure of the junction box 3. At the same time, the slide groove 322 is provided on the base 32, and the cable 6 also passes through the base 32 and extends into the junction box 3. That is, when the junction box 3 and the main box 1 are plugged in, the cover plate 31 is fixed by the interlayer of the main box 1 and the base 32, thereby enhancing the stability of the connection between the cover plate 31 and the base 32.

[0041] Preferably, a concave stopper 311 is provided on the cover plate 31. A convex stopper 321 is provided on the base 32. The cover plate 31 is connected by the engagement and sealing of the concave stopper 311 and the convex stopper 321. The stopper structure can effectively prevent the penetration of water and reduce the influence of water on the internal electronic components by means of physical isolation.

[0042] More preferably, a sleeve 324 and a first terminal block 33 are provided in the junction box 3. The threaded fastener passes through the first terminal block 33 and is screwed into the sleeve 324. Specifically, a threaded hole is provided on the sleeve 324, and the contact area between the threaded fastener and the junction box 3 is increased by the sleeve 324, thereby enhancing the connection strength of the threaded fastener. At the same time, the first terminal block 33 is supported by the sleeve 324, and there is a gap between the first terminal block 33 and the sleeve 324, which increases the air flow on the surface of the first terminal block 33, thereby enhancing the heat dissipation effect of the first terminal block 33. At the same time, when the junction box 3 is deformed by an external force, the deformation will not directly act on the first terminal block 33, thereby enhancing the protection performance of the junction box 3 and the stability of the system.

[0043] Figure 7 The vertical cross-sectional structure diagram of the electric telescopic rod in the electric intelligent external frame waterproof structure of the present invention is shown. Figure 4 and Figure 7, a sealing ring 5 is provided between the cable 6 and the junction box 3. Two convex rings 51 are provided on the outer side of the sealing ring 5 and extend in the circumferential direction. The convex rings 51 are provided on the inner and outer opposite sides of the junction box 3. By clamping the shell of the junction box 3 with the two convex rings 51, the position between the sealing ring 5 and the junction box 3 can be fixed. At the same time, another convex ring 51 is provided on the sealing ring 5 inside the junction box 3. After the first partition cavity 326 is filled with sealant, the convex ring 51 can enhance the friction between the sealing ring 5 and the sealant, and further increase the connection strength between the sealing ring 5 and the junction box 3.

[0044] In this embodiment, the outer frame body 4 includes an electric telescopic rod 42 and a fixing ring 41. Two fixing rings 41 are arranged at both ends of the length of the electric telescopic rod 42. A second baffle 431 is arranged in the motor housing 43 of the electric telescopic rod 42. The second baffle 431 and the motor housing 43 surround to form a second partition cavity 432. The cable 6 connected to the electric telescopic rod 42 passes through the second partition cavity 432. The second partition cavity 432 can effectively isolate the moisture entering the motor housing 43 along the cable 6, and prevent the moisture from affecting the electronic components inside the motor housing 43. The second partition cavity 432 is filled with sealant, and the filled sealant further improves the waterproof performance of the second partition cavity 432 while fixing the position of the cable 6, especially the position of the skin of the cable 6. Reduce the displacement between the skin of the cable 6 and the core of the cable 6, and avoid the safety hazard caused by the exposed core of the cable 6.

[0045] The specific workflow of the present invention is as follows:

[0046] When moisture enters the junction box 3 along the cable 6, it is first blocked by the sealing ring 5 on the cable 6, and then can enter the first partition cavity 326. The moisture entering the partition cavity is sealed by the sealant, and only when the sealant fails can the moisture actually penetrate into the junction box 3 and damage the first terminal board 33. Only when the moisture that penetrates into the junction box 3 is large enough, the moisture may enter the main box 1 along the gap between the line connector 143 and the junction box 3, and the gap between the phase connector and the main box 1. At this time, the moisture will extend into the second groove 141. It can be seen that the above-mentioned electric intelligent external frame waterproof structure is provided with multiple obstacles to prevent moisture from entering the junction box 3 and the main box 1, thereby improving the waterproof performance of the electric intelligent external frame.

[0047] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
