[0037] In the description of the present utility model, if the first and the second are described only for the purpose of distinguishing technical features, they should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or the sequence of the indicated technical features.

[0038] In the description of the present utility model, unless otherwise clearly defined, terms such as "arrangement", "installation", and "connection" should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0039] In the related art, for an air conditioner with a radar detection function, information such as the distance between the person detected by the radar module and the air conditioner and the direction and position of the person relative to the air conditioner is fed back to the control system of the air conditioner, and the operation mode of the air conditioner is switched through the control system, thereby improving the user experience.

[0040] The air conditioner can be a split-type air conditioner or an integrated air conditioner. When the air conditioner is a split-type air conditioner, the split-type air conditioner can be in the form of a floor-standing unit or a wall-mounted unit. The air conditioner includes an indoor unit and an outdoor unit. The indoor unit includes a casing and a panel assembly. In the front-rear direction of the indoor unit, the panel assembly is arranged on the front side of the casing, and a radar module is provided on the inner side wall of the panel assembly. The electronic control box is electrically connected to the radar module. When the air conditioner is a split-type air conditioner, the radar module can be used to detect whether there is a person in the indoor space where the indoor unit is located, and can also be used to detect the distance between the person and the indoor unit and the direction and position of the person relative to the indoor unit. When the air conditioner is an integrated air conditioner, the radar module can be used to detect whether there is a person in the indoor space where the air conditioner is located, and can also be used to detect the distance between the person and the air conditioner and the direction and position of the person relative to the air conditioner.

[0041] Taking the example that the radar module is arranged in a split-type air conditioner, the radar module can be used to detect the distance between the person and the indoor unit of the air conditioner and the direction and position of the person relative to the indoor unit. When the radar module detects that someone is approaching the indoor air outlet of the indoor unit of the air conditioner, the radar module sends the information to the electronic control box, and the electronic control box controls the driving mechanism to drive the air deflector of the indoor unit of the air conditioner to move to change the air outlet direction of the indoor unit of the air conditioner, or the electronic control box controls the driving mechanism to move the windless baffle of the indoor unit of the air conditioner to the indoor air outlet of the indoor unit of the air conditioner, and switches the indoor unit of the air conditioner to the windless mode, so as to achieve the effect of preventing direct blowing of the indoor unit of the air conditioner, thereby improving the user experience.

[0042] However, once the installation location of the wall-mounted or cabinet unit is determined, the location of the radar module is determined accordingly. The installation location of the cabinet unit's radar module is low, and when there are objects blocking it nearby, the radar signal decreases exponentially. When the radar transmitting surface of the wall-mounted radar module is perpendicular to the ground, the best signal is on the wall, resulting in more blind spots on the ground; when the radar transmitting surface is at a certain angle to the ground, the radar signal passes through the plastic parts perpendicular to the ground, resulting in inconsistent radar signal strength in various areas, making it difficult to fully exert the effect of the radar module, affecting the normal use of the air conditioner controlled by the radar module.

[0043] Moreover, affected by the model, light commercial series models such as ducted air conditioners and multi-split air conditioners have not yet adopted the function of radar module to control the air conditioner to switch the operating mode.

[0044] In view of this, the utility model proposes a radar module 10, which is separated from the body of the air conditioner. The installation position of the radar module 10 can be adjusted according to the home environment or user needs, which greatly improves the installation adaptability of the radar module 10. In addition, light commercial series models such as duct air conditioners and multi-split air conditioners can be equipped with the radar module 10 of the utility model, expanding the application of the radar module 10 in the field of air conditioners.

[0045] Reference Figures 1 to 5 The radar module 10 proposed in the embodiment of the utility model is used for an air conditioning system. The radar module 10 includes a shell 200, a positioning member 300 and a radar body 100. The shell 200 has a transmitting side 214. The radar body 100 is arranged in the shell 200. The radar body 100 includes a circuit board and a radar sensor. The radar wave generated by the radar body 100 can penetrate the shell 200 of the transmitting side 214 and be emitted to the outside of the shell 200. The radar wave can detect whether there is a person in the indoor space where the air conditioning indoor unit is located, and can also detect the distance between the person and the air conditioning indoor unit and the direction of the person relative to the air conditioning indoor unit. The radar sensor receives the echo of the radar wave, controls the control system of the air conditioner according to the detected information, and switches the operation mode of the air conditioner through the control system.

[0046] A positioning member 300 is provided on the shell 200. The positioning member 300 is located on a side of the shell 200 away from the transmitting side 214 and extends in a direction away from the shell 200. The positioning member 300 is used to penetrate an assembly hole on a corresponding carrier and is suitable for interference fit with the assembly hole so that the radar module 10 can be installed on the carrier.

[0047] It should be noted that the radar module 10 in the embodiments of the present utility model can be applied to air-conditioning systems such as split air conditioners, integrated air conditioners, duct machines, and multi-connected air conditioners. The carrier can be the panel of a split air conditioner or an integrated air conditioner, or the ceiling or wall of an indoor space. In other words, when the radar module 10 is applied to a split air conditioner or an integrated air conditioner, the radar module 10 can be arranged on the panel of the split air conditioner or the integrated air conditioner. When the radar module 10 is applied to a duct machine or a multi-connected air conditioner, the radar module 10 can be arranged on the front or side of the ceiling, and the radar module 10 can also be arranged on the wall.

[0048] Thus, the radar module 10 of the present utility model is separated from the body of the air conditioner. The radar module 10 can be applied not only to split air conditioners and integrated air conditioners, but also to light commercial series models such as duct machines and multi-connected air conditioners, expanding the application of the radar module 10 in the technical field of air conditioning equipment. Moreover, the installation position of the radar module 10 can be adjusted according to the home environment or user needs. The positioning member 300 is used to pass through the assembly hole on the corresponding carrier and is suitable for interference fit with the assembly hole, greatly improving the installation adaptability. The radar module 10 can be installed at the position with the smallest blind area and the best effect, increasing the radar coverage range and giving full play to the radar effect. The radar module 10 is small in volume, and the radar module 10 is close to the panel or ceiling, not looking too obtrusive, and can ensure the overall beauty of the home environment.

[0049] In some embodiments, the radar module 10 is a millimeter-wave radar module. The millimeter-wave seeker of the millimeter-wave radar module has the characteristics of small volume, light weight, and high spatial resolution. The millimeter-wave seeker has strong ability to penetrate fog, smoke, and dust, good anti-interference ability, and can distinguish and identify very small targets.

[0050] Interference fit is a mechanical connection method. It uses the elasticity of materials to expand and deform the hole and sleeve it on the shaft. When the hole returns to its original state, a tightening force on the shaft is generated to connect the two parts. The characteristics of this fitting method are simple structure, good centering property, and high bearing capacity, but the assembly is relatively difficult. In the interference fit tolerance zone diagram, the tolerance zone of the hole is located below the tolerance zone of the shaft, indicating that the actual size of the hole is always smaller than the actual size of the shaft. During assembly, a certain external force or heat expansion of the hole part is required to insert the shaft into the hole. After the shaft and the hole are assembled, they cannot move relative to each other. Interference fit connections are divided into cylindrical surface interference fit connections and conical surface interference fit connections. The latter uses a small amount of relative axial displacement between the shaft and the hub hole to form an interference fit, which is convenient for installation and disassembly.

[0051] In some embodiments, the positioning member 300 is provided with a frustum-shaped structure. Correspondingly, the assembly hole on the carrier is also provided as a circular hole. The frustum-shaped positioning member 300 is arranged in a direction away from the housing 200, and the diameter of the cross-section of the positioning member 300 gradually decreases. That is to say, the diameter of the end of the positioning member 300 away from the housing 200 is smaller than the diameter of the assembly hole on the carrier, and the diameter of the end of the positioning member 300 close to the housing 200 is larger than the diameter of the assembly hole. After the end of the positioning member 300 away from the housing 200 is inserted into the assembly hole on the carrier, by pressing the housing 200 forcefully, the positioning member 300 generates an axial displacement relative to the assembly hole, so that an interference fit is formed between the positioning member 300 and the assembly hole. Without using fasteners such as screws, the radar module 10 can be fixed on the carrier, which is convenient for the installation and disassembly of the radar module 10 on the carrier.

[0052] Specifically, in one embodiment, the diameter of the assembly hole on the carrier can be set to 8 mm, the diameter of the end of the positioning member 300 close to the housing 200 can be set to 8.2 mm, and the diameter of the end of the positioning member 300 away from the housing 200 can be set to 7.8 mm. After the positioning member 300 is inserted along the assembly hole and then the housing 200 is pressed forcefully, an interference fit can be formed between the positioning member 300 and the assembly hole.

[0053] It can be understood that the positioning member 300 can also be provided with a prism-shaped structure, and the assembly hole on the carrier is provided as a corresponding polygonal hole or circular hole, which is not limited herein.

[0054] It can be understood that the positioning member 300 can also be provided with a cylindrical structure or a prismatic structure, and the assembly hole is correspondingly provided as a circular hole or a polygonal hole. When the positioning member 300 is provided with a cylindrical structure or a prismatic structure, in order to facilitate the insertion of the positioning member 300 into the assembly hole, a guiding surface can be provided on the end face of the positioning member 300 around the end away from the housing 200.

[0055] Refer to Figure 3 、 Figure 4 In some embodiments, a mating surface 222 is provided on the side of the housing 200 where the positioning member 300 is located. An adhesive layer 230 is provided on the mating surface 222, and a protective film is provided on the surface of the adhesive layer 230. When installing the radar module 10, the protective film on the adhesive layer 230 is torn off, the positioning member 300 is inserted into the assembly hole to form an interference fit, and at the same time, the radar module 10 is pasted on the carrier by using the adhesive layer 230. Press forcefully for a certain period of time to make the adhesive layer 230 fit tightly with the surface of the carrier to ensure the bonding strength. Through the interference fit between the positioning member 300 and the assembly hole and the adhesive layer 230, the assembly strength of the radar module 10 can be ensured, and without using fasteners such as screws, so the installation is convenient.

[0056] Refer to Figure 3 、 Figure 4, in some embodiments, the housing 200 includes a front shell 210 and a rear cover 220 connected to the front shell 210. The front shell 210 is provided with a receiving groove 215 for receiving the radar body 100. The front shell 210 is provided with a limiting structure for limiting the radar body 100. The radar body 100 can be assembled in the housing 200 through the limiting structure. The transmitting side 214 is arranged on the front shell 210, and the positioning member 300 is arranged on the rear cover 220.

[0057] Referring to Figures 1 to 5 , in some embodiments, the housing 200 is provided with a mounting member 240. The mounting member 240 is detachably connected to the housing 200. The mounting member 240 is used for assembling on a carrier. The mounting member 240 is provided with an avoidance hole 241. The positioning member 300 passes through the avoidance hole 241. The mating surface 222 can be fixedly connected to the mounting member 240 through an adhesive layer 230. When the radar module 10 is applied to light commercial series models such as air duct machines and multi-connected air conditioners, the radar module 10 is usually installed on the ceiling or wall. Since substances such as wall paint will be applied on the ceiling or wall, there may be a phenomenon that the adhesive layer 230 is not firmly adhered to the ceiling or wall due to the existence of wall paint. Therefore, the mounting member 240 is first assembled on the wall, and then the housing 200 is adhered to the surface of the mounting member 240 through the adhesive layer 230, thereby ensuring the adhesion strength.

[0058] It can be understood that the mounting member 240 can be detachably connected to the housing 200 through a fixing member or a detachable connection structure. Specifically, referring to Figure 1 , Figure 3 , Figure 4 , Figure 6 , along the first direction, the upper parts of both ends of the mounting member 240 are provided with connecting columns 242. The connecting columns 242 extend in a direction away from the mounting member 240. The connecting columns 242 are provided with guiding surfaces. Both ends of the front shell 210 are provided with side plates 211. The side plates 211 are provided with connecting holes 213. After the mounting member 240 is assembled on the carrier, the avoidance hole 241 on the mounting member 240 communicates with the assembly hole on the carrier. Then, the positioning member 300 of the radar module 10 is inserted into the assembly hole along the avoidance hole 241. The radar module 10 is pressed, so that the positioning member 300 is in interference fit with the assembly hole. At the same time, the side plates 211 at both ends of the front shell 210 are pressed against the guiding surfaces of the connecting columns 242. The radar module 10 is continuously pressed, and the connecting columns 242 cause elastic deformation of the side plates 211 at both ends of the front shell 210. The connecting columns 242 are inserted into the connecting holes 213 of the side plates 211, and the adhesive layer 230 on the mating surface 222 is adhered to the surface of the mounting member 240, and the installation of the radar module 10 can be completed.

[0059] Referring to Figure 4 , Figure 5, in some embodiments, the transmitting side 214 has a transmitting surface 2141, and the plane where the circuit board of the radar body 100 is located is parallel to the transmitting surface 2141 of the transmitting side 214, so as to ensure the uniformity of the radar signal intensity in all directions emitted along the transmitting surface 2141.

[0060] In the related art, the transmitting surface 2141 of the radar module 10 used in the split air conditioner and the integrated air conditioner can only be perpendicular to the scene, so there are problems such as a small radar coverage area, a large blind area, or a large radar coverage area but poor signal effect. To solve the above problems, after the radar module 10 of the present utility model is assembled on the carrier, there is an included angle between the transmitting surface 2141 of the radar module 10 and the horizontal plane, and this included angle is an acute angle less than 90°, so as to reduce the radar blind area and improve the detection effect.

[0061] Specifically, referring to Figure 5 , there is an angle between the transmitting surface 2141 of the transmitting side 214 and the center line of the positioning member 300, and this included angle is an acute angle less than 90°. Therefore, whether the radar module 10 is installed on the side or wall of the ceiling or on the bottom surface of the ceiling, the included angle between the transmitting surface 2141 and the horizontal plane is an acute angle less than 90°, and the plane where the circuit board of the radar body 100 is located is parallel to the transmitting surface 2141 of the transmitting side 214, so as to be able to reduce the radar blind area and improve the detection effect.

[0062] Practice has proved that when the included angle between the transmitting surface 2141 and the horizontal plane is set to 40° to 50°, it can ensure an increase in the effective coverage range of the radar, reduce the blind area, and the radar signal effect is good, thus solving the problem of having to choose between the radar coverage area and the signal uniformity of the radar module 10 in the related art.

[0063] When the included angle between the radar transmitting surface 2141 and the horizontal plane is 50°, the effect is relatively good. The radar is installed at a height of 2.7m. It is actually measured that when a person walks, it can cover a range with a radius of 6m and an angle of 160°. When a person lies flat and makes slight movements (turns over), it can cover a range with a radius of 5m and an angle of 160°.

[0064] Referring to Figure 5 , in some embodiments, the housing 200 is provided with an outlet 250. Along the center line direction of the positioning member 300, the positioning member 300 is provided with a wire passing hole 310. The outlet 250 is communicated with the wire passing hole 310 and the inner cavity of the housing 200. The circuit board of the radar body 100 is provided with a terminal, and the terminal is connected with a radar wire harness 110. The radar wire harness 110 passes through the outlet 250 and the wire passing hole 310 and is connected to the circuit board of the control system of the air conditioner. Thus, the positioning member 300 can not only play a role in positioning the radar module 10, but also play a role in wire routing, simplify the internal structure of the radar module 10, improve the mold manufacturing efficiency, and make the appearance of the radar module 10 beautiful.

[0065] In some embodiments, the diameter of the wire hole 310 is R1, the diameter of the wire outlet 250 is R2, and the diameter of the radar harness 110 is R3, wherein R1>R2>R3. After the radar harness 110 passes through the wire outlet 250, the gap between the wire outlet 250 and the radar harness 110 is smaller than the gap between the wire hole 310 and the radar harness 110, so as to ensure the pulling force of the radar harness 110 and avoid damaging the radar harness 110 during the assembly process.

[0066] In some embodiments, the gap between the side wall of the wire hole 310 and the radar harness 110 is filled with sealant. Since the diameter of the wire outlet 250 is smaller than the diameter of the wire hole 310, it is equivalent to providing a retaining rib extending from the circumference of the hole wall of the wire hole 310 to the axial direction of the wire hole 310, and the sealant has low fluidity. During the filling process, the sealant will not flow from the wire outlet 250 to the inside of the radar module 10. After the sealant solidifies, it can effectively fix the radar harness 110. There is no need to set a winding structure inside the radar module 10 to increase the pulling force of the radar harness 110, which facilitates the assembly of the radar module 10. In addition, the sealant forms a sealing structure between the side wall of the wire hole 310 and the radar harness 110, which has a good sealing effect and prevents water vapor from entering the inside of the radar module 10.

[0067] In a specific embodiment, when the diameter of the radar harness 110 is 4.2 mm, the diameter of the wire hole 310 is set to 5.6 mm, and the diameter of the wire outlet 250 is set to 4.5 mm, which is equivalent to providing a retaining rib on the circumference of the hole wall of the wire hole 310. After the radar harness 110 passes through the wire outlet 250 and the wire hole 310, sealant is poured into the wire hole 310. The fluidity of the sealant is low.
