[0036] like Figures 1 to 6As shown, the first aspect of the utility model provides a housing assembly 100, comprising:

[0037] The box body 10 defines a first installation cavity 11. A first opening is provided at a first end of the box body 10, and the first opening is communicated with the first installation cavity 11. A flange structure 14 is further provided at the first end of the box body 10, and a water guide groove 15 is formed on a side of the flange structure 14 away from the first installation cavity 11.

[0038] The cover body 20 is disposed on the first opening, and an assembly gap 16 is formed between the cover body 20 and the box body 10 . The water guide groove 15 is used to guide the liquid entering from the assembly gap 16 out.

[0039] It is understandable that the housing assembly 100 can be applied to sensors, controllers, actuators, electric control boxes, indoor units of HVAC equipment, etc. The box body 10 can be a box body 10 structure with a rectangular cross section. The box body 10 forms a first installation cavity 11 inside for installing electrical components, etc. A first opening is provided at one end of the box body 10 in the thickness direction, and the first opening is the opening of the first installation cavity 11. A flange structure 14 is provided on the box body 10 at a circumferential position of the first opening. The flange structure 14 can be an L-shaped structure. A water guide groove 15 is formed between the side of the flange structure 14 away from the first installation cavity 11 and the box body 10. The flange structure 14 can be arranged around the first opening along the circumference of the first opening, or can be arranged along the circumference for a section. The cover 20 may be a structure with a rectangular cross section. The cover 20 is adapted to the first opening. The cover 20 may be connected to the box body 10 by snap-fit ​​or pivot connection and cover the first opening. The side wall of the cover 20 is located at the periphery of the flange structure 14 after the cover 20 covers the first opening, so that the side wall of the cover 20 can form a first seal, and the flange structure 14 is a second seal, which enhances the sealing and waterproof properties of the housing assembly 100. The water guide groove 15 is arranged on the inner side of the connection between the cover 20 and the box body 10, so that the water that passes through the connection gap between the box body 10 and the cover 20 can be drained out by the water guide groove 15, further improving the waterproof effect of the housing assembly 100.

[0040] The shell assembly 100 of the utility model is covered on the first opening of the box body 10 by the cover body 20 to achieve the sealing of the first installation cavity 11. The end of the box body 10 connected to the cover body 20 is provided with a flange structure 14, and the outer peripheral side of the flange structure 14 is provided with a water guide groove 15. After the cover body 20 is buckled on the box body 10, the flange structure 14 extends into the second installation cavity 21 of the cover body 20, so that the flange structure 14 can block the water that passes through the connection gap between the cover body 20 and the box body 10, and the water guide groove 15 can drain the water out, thereby reducing the phenomenon that water enters the box body 10 and causes the electrical components to fail due to water.

[0041] like Figures 2 to 3As shown, in some embodiments of the present invention, the cover body 20 defines a second installation cavity 21 having a second opening. The cover body 20 covers the first opening, and at least a portion of the water guide groove 15 is located in the second installation cavity 21 .

[0042] It can be understood that the cover body 20 defines a second installation cavity 21 with a second opening through its side walls and bottom wall. After the cover body 20 is snap-fitted and connected to the box body 10, the flange structure 14 extends into the second installation cavity 21, so that the water guide groove 15 is also located in the second installation cavity 21. At this time, the part where the cover body 20 is connected to the box body 10 is located on the outer peripheral side of the water guide groove 15, so that the water guide groove 15 is located on the inner peripheral side of the assembly gap 16. The water guide groove 15 is arranged between the assembly gap 16 and the second installation cavity 21, so that the liquid entering from the assembly gap 16 can be received by the water guide groove 15 and diverted to the outside of the shell assembly 100, so as to reduce the phenomenon that water enters the box body 10 and causes the electrical components to fail due to water.

[0043] like Figures 2 to 3 As shown, in some embodiments of the utility model, the box body 10 includes a first bottom plate 12 and a first side plate 13. Along the thickness direction of the box body 10, the bottom end of the first side plate 13 is connected to the first bottom plate 12, and the first side plate 13 extends along the circumference of the first bottom plate 12. A first installation cavity 11 is defined between the first bottom plate 12 and the first side plate 13, and a flange structure 14 is arranged at the top end of the first side plate 13.

[0044] It can be understood that the first bottom plate 12 can be a rectangular plate structure, and the first side plate 13 extends along the edge of the first bottom plate 12. When the first bottom plate 12 is rectangular, the first side plate 13 is mouth-shaped and includes four rectangular plates. The bottom end of the first side plate 13 is connected to the first bottom plate 12, which can be achieved by integral injection molding to improve the overall strength of the box body 10. A flange structure 14 can be set at the top of the first side plate 13 by injection molding. After installation, the flange structure 14 located at the top of the first side plate 13 is inserted into the second installation cavity 21 of the cover body 20. The first side plate 13 cooperates with the first limiting rib 23 of the cover body 20, which can be a snap-fit ​​fit, that is, the first limiting rib 23 is also mouth-shaped, and the area enclosed by the first limiting rib 23 is larger than the area enclosed by the first side plate 13. The first limiting rib 23 is sleeved on the first side plate 13 to achieve a snap-fit ​​fit, and the flange structure 14 can be connected to the cover body 20.

[0045] like Figure 4 As shown, in some embodiments of the utility model, the cover body 20 includes a second bottom plate 22 and a first limiting rib 23. Along the thickness direction of the cover body 20, the bottom end of the first limiting rib 23 is connected to the first bottom plate 12, and the first limiting rib 23 extends along the circumference of the second bottom plate 22. The first limiting rib 23 is arranged on the outer peripheral side of the flange structure 14, and the flange structure 14 abuts against the second bottom plate 22.

[0046] It can be understood that the second bottom plate 22 can be a rectangular plate structure, the first limiting rib 23 extends along the edge of the second bottom plate 22, when the second bottom plate 22 is rectangular, the first limiting rib 23 can be mouth-shaped, including four rectangular plates, the bottom end of the first limiting rib 23 is connected to the second bottom plate 22, and can be achieved by injection molding to improve the overall strength of the cover 20, the first limiting rib 23 is an enclosed structure, and the first limiting rib 23 is sleeved on the outer peripheral side of the flange structure 14 of the first side plate 13 after the box body 10 and the cover 20 are buckled, and the top end of the flange structure 14 can be abutted against the second bottom plate 22 to achieve the limiting function of the cover 20 being installed in place. The first limiting rib 23 is also connected to the first side plate 13 at this time, so that the cover 20 is covered on the first opening.

[0047] like Figures 4 to 6 As shown, in some embodiments of the utility model, the cover body 20 also includes a second limiting rib 24, along the height direction of the cover body 20, the bottom end of the second limiting rib 24 is connected to the second bottom plate 22, and the second limiting rib 24 extends along the circumference of the second bottom plate 22, the second limiting rib 24 is arranged on the inner circumference side of the first side plate 13, and a sealing groove 25 is formed between the first limiting rib 23 and the second limiting rib 24, and the flange structure 14 extends into the sealing groove 25.

[0048] It can be understood that a second limiting rib 24 can be set on the inner side of the first side panel 13, and the second limiting rib 24 and the first limiting rib 23 are both connected to the second bottom plate 22, and the second limiting rib 24 and the first limiting rib 23 are spaced apart. A sealing groove 25 is defined between the first side panel 13, the second limiting rib 24 and the second bottom plate 22, and the sealing groove 25 can be arranged around the second bottom plate 22 along the circumference of the second bottom plate 22. The flange structure 14 can also be arranged in a ring shape. After the box body 10 and the cover body 20 are assembled, the flange structure 14 extends into the sealing groove 25, and serves as a seal behind the mating surface of the first side panel 13 and the first limiting rib 23, thereby further improving the waterproof effect.

[0049] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the housing assembly 100 further includes a seal 30 , which is disposed in the sealing groove 25 , and the seal 30 abuts against the flange structure 14 and the cover body 20 , respectively.

[0050] It is understandable that the seal 30 is adapted to the sealing groove 25. When the sealing groove 25 is annular, the seal 30 is also annular. The seal 30 can be a sealing ring. The seal 30 can be made of elastic rubber or silicone, or can be made of other materials with good sealing properties. The seal 30 is embedded and installed in the sealing groove 25, and can be an interference connection, that is, the seal 30 is squeezed by the first side plate 13 and the second limiting rib 24 to provide a better sealing effect. After the cover 20 and the box body 10 are buckled, the top of the flange structure 14 extends into the sealing groove 25 and squeezes the seal 30, so that the seal 30 is deformed, and the top surface of the flange structure 14 forms an enlarged contact surface of the seal 30, increasing the contact area with the seal 30, and pressing the seal 30 more firmly, further improving the waterproof effect, and reducing the phenomenon of water entering the box body 10 and soaking the electrical components.

[0051] like Figures 2 to 4 As shown, in some embodiments of the present invention, the first side plate 13, the first limiting rib 23 and the second limiting rib 24 are all arranged in a ring shape.

[0052] It can be understood that the first side plate 13 is arranged around the first bottom plate 12 along the circumference of the first bottom plate 12, and the first limiting rib 23 and the second limiting rib 24 are arranged around the second bottom plate 22 along the circumference of the second bottom plate 22, so that the first side plate 13, the first limiting rib 23 and the second limiting rib 24 are all annular structures. When the cover body 20 is buckled on the box body 10, the annular waterproof structure can provide better waterproof effect and reduce waterproof weak points.

[0053] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the seal 30 includes a sealing ring, which is installed in the sealing groove 25 along the circumference of the sealing groove 25 and is compressed between the sealing groove 25 and the flange structure 14 .

[0054] It can be understood that the seal 30 can be a sealing ring, which is adapted to the annular sealing groove 25 and is interference-fitted in the sealing groove 25. After the cover body 20 and the box body 10 are assembled, the sealing ring is squeezed by the first limiting rib 23 and the second limiting rib 24 and the flange structure 14, causing deformation, and is further pressed and fills the gap between the cover body 20 and the box body 10, providing a good waterproof effect.

[0055] like Figure 5 and Figure 6As shown, in some embodiments of the utility model, the flange structure 14 includes a first extension portion 141 and a second extension portion 142. Along the thickness direction of the box body 10, the bottom end of the first extension portion 141 is connected to the first side plate 13, and the second extension portion 142 is arranged at the top end of the first extension portion 141, and the second extension portion 142 is arranged on the side of the first extension portion 141 away from the first installation cavity 11, and the top end of the second extension portion 142 abuts against the seal 30.

[0056] It is understandable that the flap can be arranged in an L-shape, that is, the cross section of the flange structure 14 is L-shaped along the cross-sectional direction of the box body 10. The flange structure 14 can be composed of an integrally formed first extension portion 141 and a second extension portion 142, one end of the first extension portion 141 is connected to the first side plate 13, and the second extension portion 142 is arranged on the side of the first extension portion 141 away from the first installation cavity 11, and the second extension portion 142 is arranged at one end of the first extension portion 141 away from the first side plate 13, and the second extension portion 142 extends in a direction away from the first installation cavity 11. After the cover body 20 and the box body 10 are assembled, the top surface of the second extension portion 142 abuts against the sealing member 30, and the sealing member 30 is squeezed to form an enlarged contact surface with the sealing ring, thereby increasing the contact area of ​​the sealing ring, which is conducive to tightening the sealing ring more firmly, further preventing water from entering the box body 10, and preventing PCBA failure.

[0057] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the outer surface of the second extension portion 142 on the side facing away from the first installation cavity 11 is arranged in an inclined surface, and is inclined downward from the end of the second extension portion 142 close to the sealing ring to the end of the second extension portion 142 away from the sealing ring, that is, the second extension portion 142 can make the water on the surface slide along the inclined surface into the water guide groove 15, thereby improving the water guide effect.

[0058] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the flange structure 14 is arranged in a ring shape, and the flange structure 14 extends along the circumference of the first side plate 13 in a ring shape, so that the flange structure 14 can be adapted to the annular sealing groove 25, further improving the waterproof effect and water guiding effect.

[0059] like Figure 2 and Figure 6 As shown, in some embodiments of the present invention, along the depth direction of the water guide groove 15, the length of the second extension portion 142 is less than the length of the first side plate 13, and along the thickness direction of the box body 10, the top end of the first limiting rib 23 abuts against the top end of the first side plate 13.

[0060] It can be understood that after the box body 10 and the cover body 20 are installed in cooperation, the top end of the first side plate 13 abuts against the top end of the first limiting rib 23, and the flange structure 14 extends into the sealing groove 25, so that the first seal connecting the box body 10 and the cover body 20 is achieved by the end surface of the top end of the first side plate 13 and the top end of the first limiting rib 23 fitting together, and the second seal is achieved by the inner water guide groove 15. The water entering the first sealing gap can be discharged from the water guide groove 15. After the water guide groove 15, a third seal is performed by a sealing ring. After the sealing ring is pressed by the wall of the sealing groove 25 and the flange structure 14, it can fill the fitting gap here, thereby further improving the sealing effect and preventing water from entering the box body 10 to cause failure of the electrical components.

[0061] like Figure 6 As shown, in some embodiments of the present invention, the flange structure 14 and the sealing groove 25 are clearance-matched.

[0062] It can be understood that, along the thickness direction of the box body 10, the top of the flange structure 14 is the sealing ring contact surface, and the flange structure 14 and the sealing groove 25 are clearance-matched, so that the sealing ring contact surface of the flange structure 14 can stand at about 60% of the cross-section of the sealing groove 25, which is beneficial for the flange structure 14 to press the sealing ring more firmly, further prevent water from entering the box body 10, and prevent the internal electrical components from failing due to water.

[0063] like Figure 6 As shown, in some embodiments of the present invention, after the box body 10 and the cover body 20 of the shell assembly 100 are assembled, the flange structure 14 of the box body 10 will squeeze the sealing ring, and the sealing ring is compressed by about 40%, so that the box body 10 and the cover body 20 fit more tightly and prevent water from entering the control box.

[0064] The second aspect of the present invention provides a control system, including a sensor. The sensor includes a housing assembly 100. The housing assembly 100 is the housing assembly 100 provided in the first aspect of the present invention.

[0065] The control system proposed in the second aspect of the present invention has the same beneficial effects as the housing assembly 100 proposed in the first aspect of the present invention. The control system proposed in the second aspect of the present invention may be an air conditioning system, and the housing assembly 100 may be a temperature sensor, or may be other sensors, controllers, actuators, electric control boxes, housings of indoor units of HVAC equipment, etc.

[0066] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
