The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0028] like Figure 1 and Figure 2 As shown, on the one hand, the embodiments of this application provide a human sensing fixing structure, which can improve the installation convenience and reliability of the human body sensing device 2.

[0029] The human body sensor fixing structure includes a base 1; here, the base 1 can be, for example, the base 1 of an equipment where a human body sensor 2 is located, such as an indoor unit of an air conditioner. The base 1 has a first sidewall 11 and a second sidewall 12 arranged at intervals, which are used to clamp and fix the human body sensor 2. The first sidewall 11 has a hook portion 111 and an elastic protrusion 112, which are arranged at intervals along the insertion direction of the human body sensor 2. Figure 4 As shown, the protrusion height of the elastic protrusion 112 is less than the protrusion height of the hook portion 111.

[0030] When it is necessary to install the human body sensor 2, one end of the human body sensor 2 can be pressed against the second side wall 12, and the first side wall 11 can be elastically deformed away from the second side wall 12, so that the other end of the human body sensor 2 can pass over the hook part 111, so that the human body sensor 2 can enter the area between the hook part 111 and the main body of the base 1; after the human body sensor 2 passes over the hook part 111, the first side wall 11 elastically resets so that the elastic protrusion 112 abuts against the human body sensor 2, and the elastic protrusion 112 elastically deforms to press the human body sensor 2 against the second side wall 12; in this way, on the one hand, the hook part 111 can be used to restrict the human body sensor 2 from coming out of the area between the first side wall 11 and the second side wall 12, and on the other hand, the elastic deformation force of the elastic protrusion 112 can be used to reliably clamp the human body sensor 2 between the first side wall 11 and the second side wall 12.

[0031] Compared with related technologies, the human body sensing device 2 provided in this application embodiment has a first sidewall 11 and a second sidewall 12 on the base 1, and a hook portion 111 and an elastic protrusion portion 112 on the first sidewall 11. On the one hand, the hook portion 111 can be used to restrict the human body sensing device 2 from coming out of the area between the first sidewall 11 and the second sidewall 12. On the other hand, the elastic deformation force of the elastic protrusion portion 112 can be used to reliably clamp the human body sensing device 2 between the first sidewall 11 and the second sidewall 12. The assembly and installation process is more convenient, and the reliability after assembly and installation is higher.

[0032] like Figure 5As shown, in some embodiments, the width of the elastic protrusion 112 can increase gradually along the insertion direction of the human body sensor 2. Here, the width direction of the elastic protrusion 112 is perpendicular or inclined to the insertion direction of the human body sensor 2, and the width direction of the elastic protrusion 112 is perpendicular or inclined to the protrusion height of the elastic protrusion 112. In other words, the width of the elastic protrusion 112 gradually increases along the insertion direction of the human body sensor 2, so that the elastic protrusion 112 presents a trapezoidal structure with a smaller side near the hook portion 111 and a larger side away from the hook portion 111. Thus, during the insertion of the human body sensor 2, the contact area between the side of the elastic protrusion 112 near the hook portion 111 and the human body sensor 2 is small, making the elastic protrusion 112 easy to elastically deform and press the human body sensor 2 against the second side wall 12. Meanwhile, the side of the elastic protrusion 112 near the hook portion 111 is larger, which can increase the deformation limit of the elastic protrusion 112, so that the elastic protrusion 112 can quickly elastically deform and spring back to its original position after being squeezed, so as to reliably clamp the human body sensor 2 between the first side wall 11 and the second side wall 12.

[0033] The number of elastic protrusions 112 can be set according to actual needs, and there can be one or more, which is not limited in this embodiment. In some embodiments, a plurality of elastic protrusions 112 can be provided on the first sidewall 11, and the plurality of elastic protrusions 112 are arranged sequentially at intervals along the width direction of the first sidewall 11. In this way, the plurality of elastic protrusions 112 can elastically deform and press the human body sensing device 2 against the second sidewall 12, further increasing the installation reliability of the human body sensing device 2.

[0034] like Figure 1 and Figure 2 As shown, in some embodiments, a first insertion portion 121 may be provided on the second sidewall 12, and a second insertion portion 23 may be provided at the end of the human body sensing device 2. The first insertion portion 121 is used for insertion and fixation of the second insertion portion 23. The structural forms of the first insertion portion 121 and the second insertion portion 23 can be set according to actual needs, and the embodiments of this application do not limit this; for example, one of the first insertion portion 121 and the second insertion portion 23 is a connector, and the other is a hole. By providing the first insertion portion 121 on the second sidewall 12, the connection reliability between the second sidewall 12 and the human body sensing device 2 can be further increased by utilizing the insertion relationship.

[0035] In some embodiments, the base 1 may be provided with a first insertion plate portion 13; the first insertion plate portion 13 is located between the first side wall 11 and the second side wall 12, and the first insertion plate portion 13 may be spaced apart from the first side wall 11 / second side wall 12. The human body sensing device 2 may have a sensing side 21 and a back side 22 disposed opposite to each other. The sensing side 21 is used to transmit and receive human body sensing signals; the back side 22 may be provided with a first insertion slot, and the first insertion plate portion 13 is used to be inserted and fixed with the first insertion slot. In this way, the back side 22 of the human body sensing device 2 can be fixed to the base 1 through the first insertion plate portion 13 and the first insertion slot, so that multiple sides of the human body sensing device 2 are fixed to the base 1, thereby improving the installation reliability of the human body sensing device 2.

[0036] In some examples, a second insertion plate portion 14 may be provided on the base 1. The second insertion plate portion 14 is located between the first side wall 11 and the second side wall 12, and the second insertion plate portion 14 and the first insertion plate portion 13 are arranged at intervals. Here, the second insertion plate portion 14 may be spaced apart from the first side wall 11 / second side wall 12. The back side 22 of the human body sensing device 2 may be provided with a second insertion slot, and the second insertion plate portion 14 is used for insertion and fixation into the second insertion slot. In this way, the back side 22 of the human body sensing device 2 can be fixed to the base 1 through the first insertion plate portion 13 and the first insertion slot, and through the second insertion plate portion 14 and the second insertion slot, so that the back side 22 of the human body sensing device 2 is fixed to the base 1 through multiple insertion points, thereby improving the installation reliability of the human body sensing device 2.

[0037] For example, the top of the second insert portion 14 can be recessed along the insertion direction of the human body sensor 2 to form a recessed latching portion 141. The recessed latching portion 141 has a first support surface 1411 and a second support surface 1412 disposed opposite to each other, which are used to support the human body sensor 2. Here, the included angle between the first support surface 1411 and the second support surface 1412 is in the range of 85° to 95°, for example, 85°, 86°, 87°, 88°, 89°, 90°, 91°, 92°, 93°, 94° or 95°. Within the above included angle range, the first support surface 1411 and the second support surface 1412 can reliably and stably support the human body sensor 2.

[0038] For example, the base 1 may be provided with a transverse connecting plate portion 15 and a plurality of first insert plate portions 13. The transverse connecting plate portion 15 may extend along a first direction and sequentially connect the plurality of first insert plate portions 13, the first direction being the direction from the first side wall 11 towards the second side wall 12. The plurality of first insert plate portions 13 may be sequentially spaced along the first direction, and the plurality of first insert plate portions 13 are formed on the side of the transverse connecting plate portion 15 facing the second insert plate portion 14; the back side 22 of the human body sensing device 2 may be provided with a plurality of first insertion slots, and the plurality of first insert plate portions 13 and the plurality of first insertion slots are arranged one-to-one. In this way, the plurality of first insert plate portions 13 and the plurality of first insertion slots can be inserted one-to-one, and the transverse connecting plate portion 15 can be used to connect and support the plurality of first insert plate portions 13, thereby increasing the installation stability and reliability of the human body sensing device 2.

[0039] like Figure 3 As shown, by way of example, the first insertion plate portion 13 may be provided with a guide slope 131, a stop limiting surface 132, and an assembly bearing surface 133 on the side facing the second insertion plate portion 14. The guide slope 131, the stop limiting surface 132, and the assembly bearing surface 133 are arranged obliquely in sequence along the insertion direction of the human body sensing device 2. The guide slope 131 is used to guide when the human body sensing device 2 and the first insertion plate portion 13 are inserted, the stop limiting surface 132 is used to limit the stop portion of the human body sensing device 2, and the assembly bearing surface 133 is used to support the human body sensing device 2. The included angle between the guide slope 131 and the stop limiting surface 132 is smaller than the included angle between the stop limiting surface 132 and the assembly bearing surface 133, so that the first insertion plate portion 13 can be easily inserted into the first insertion slot and the human body sensing device 2 can be reliably supported by the assembly bearing surface 133.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments, the base 1 may be provided with multiple wire clips 16, which are arranged sequentially at intervals along the preset wiring direction of the human body sensing device 2 to fix the conductive wires of the human body sensing device 2.

[0041] like Figures 1 to 5 As shown, on the other hand, this application embodiment provides an air conditioner indoor unit, which includes a human-sensor fixing structure, an indoor fan 3, and a human body sensor 2 as provided in any of the above embodiments. The indoor fan 3 is mounted on a base 1, and the human body sensor 2 is disposed on the human-sensor fixing structure. The type of air conditioner indoor unit can be determined according to actual needs, and can be, for example, a wall-mounted air conditioner, a cabinet air conditioner, etc. This application embodiment does not limit this. The air conditioner indoor unit provided in this application embodiment has the above-mentioned human-sensor fixing structure, thus improving the installation convenience and reliability of the human body sensor 2.

[0042] In some embodiments, the indoor unit of the air conditioner may include an indoor heat exchanger 4, which may be mounted on the base 1.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application.
