Technical Field

[0001] This utility model relates to the field of sensors, and in particular to a novel snap-fit ​​infrared sensing housing. Background Technology

[0002] In current designs, home appliances are increasingly pursuing intelligence and the Internet of Things, which has led to an increasing number of sensors on various appliances and a stronger sensing capability. For lighting fixtures, in addition to traditional photosensitive sensors, sensors such as sound sensors, microwave sensors, and infrared sensors are also set up to assist in control.

[0003] For microwave or infrared sensors, existing designs typically install them in the middle of the lamp cover, using a snap-fit ​​method. The sensor's bottom interface is connected to the lamp's light-emitting panel, thus achieving both electrical and structural connectivity.

[0004] However, the existing snap-fit ​​structure has poor versatility and requires the use of specific products to match the thickness of the lampshade. As we all know, different usage environments and different types of lampshade materials have different thicknesses. Therefore, a new type of snap-fit ​​infrared sensing housing with a simple structure and strong versatility is needed to meet the needs of lampshades of different thicknesses. Utility Model Content

[0005] The main purpose of this utility model is to provide a new type of snap-on infrared sensing housing that is simple in structure, highly versatile, and can meet the needs of lampshades of different thicknesses.

[0006] This utility model proposes a novel snap-fit ​​infrared sensing housing, including a housing body; the housing body has an upper connecting clip and a lower elastic clip protruding outward from its side, and the lower elastic clip is located below the upper connecting clip; the housing body is snapped onto an external component by the cooperation of the upper connecting clip and the lower elastic clip.

[0007] The lower elastic clip includes an elastic guide surface at the bottom and an elastic abutment surface at the top. The elastic guide surface and the elastic abutment surface are connected at an angle to form an outwardly protruding clip head. The elastic abutment surface is inclined upward and inward relative to the clip head. The elastic guide surface is inclined downward and inward relative to the clip head.

[0008] Preferably, the housing body is provided with a hollow groove, and the lower elastic clip is positioned opposite to the hollow groove.

[0009] Preferably, the lower end of the elastic guide surface is connected to the lower edge of the hollow groove.

[0010] Preferably, the card head has a pointed or rounded corner structure.

[0011] The elastic guide surface is an inclined plane or an inclined curved surface.

[0012] The elastic contact surface is an inclined plane or an inclined curved surface.

[0013] Preferably, the housing body includes a base and a top cover connected together, the top cover is provided with a Fresnel lens, and the upper connecting clip and the lower elastic clip are both disposed on the base.

[0014] Preferably, the housing body includes a base and a top cover connected together, the top cover is provided with a Fresnel lens, the upper connecting clip is disposed on the top cover, and the lower elastic clip is disposed on the base.

[0015] Preferably, a protective groove is recessed at the position of the upper connecting clip opposite to the upper edge of the base.

[0016] Preferably, the housing body includes a base and a top cover connected together, and the top cover is provided with a Fresnel lens; one of the inner side of the base and the outer side of the top cover is provided with an annular retaining ring, and the other is provided with an annular retaining groove, so that the top cover and the base are connected by the retaining ring and the retaining groove engaging.

[0017] Preferably, the bottom of the housing body is provided with a through hole, and the bottom port of the circuit board can extend out from the through hole.

[0018] Preferably, the housing body is integrally formed, a Fresnel lens is provided on the top of the housing body, and a circuit board entry hole is provided on the bottom of the housing body, so that the circuit board can be inserted into and locked into the housing body through the circuit board entry hole.

[0019] Preferably, an assembly positioning groove is provided on the bottom of the housing body, which facilitates automated assembly.

[0020] The beneficial effects of this novel snap-on infrared sensing housing are as follows:

[0021] 1. An upper connecting clip and a lower elastic clip are provided on the side of the housing body. These clips work together to engage external components (such as lampshades, lamp housings, or other components requiring sensor mounting). During engagement, the external component presses against the lower elastic clip to lock into place between the upper connecting clip and the lower elastic clip. The lower elastic clip is a pressable and deformable clip to facilitate the engagement of the external component.

[0022] The lower elastic locking component includes a lower elastic guide surface and an upper elastic abutment surface. The elastic guide surface and the elastic abutment surface are connected at an angle to form a protruding locking head. The elastic abutment surface is inclined upward and inward relative to the locking head and can be pressed downward; the elastic guide surface is inclined downward and inward relative to the locking head and can be pressed upward and inward. The locking head protrudes from the outermost side of the lower elastic locking component. When assembling with the outer component, the housing body is inserted into the connection port of the outer component from top to bottom. The side wall of the connection port is assembled onto the elastic abutment surface along the elastic guide surface. During the assembly process, the side wall of the connection port presses against the elastic guide surface so that the locking head is locked below the side wall of the connection port. The side wall of the connection port abuts against the elastic abutment surface and is secured between the upper connecting component and the elastic abutment surface.

[0023] The elastic abutment surface can be pressed downwards, so the distance between the elastic abutment surface and the upper connecting clip can be adjusted to accommodate external parts with different sidewall thicknesses at the connection port.

[0024] Moreover, the side wall of the connector can be placed at any position on the elastic contact surface. As long as the clip head is placed under the side wall of the connector, the new type of snap-on infrared sensing housing and the external component can be connected. It can adapt to external components with different thicknesses of the side wall of the connector and has strong versatility.

[0025] 2. An assembly positioning groove is provided on the bottom of the housing body. By setting the assembly positioning groove, the machine can accurately judge the real-time posture of the new snap-fit ​​infrared sensor housing, thereby facilitating automated installation.

[0033] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0034] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0035] Reference Figures 1 to 4 An embodiment of the novel snap-fit ​​infrared sensing housing of this utility model is presented:

[0036] A novel snap-fit ​​infrared sensing housing includes a housing body, which includes a base 2 and a top cover 1.

[0037] The top of the cover 1 has a Fresnel lens 12 integrally formed in the middle. The lower side of the cover 1 has an annular groove 14. The inner side of the base 2 has an annular retaining ring 23. The cover 1 is snapped and fixed on the base 2 by the cooperation of the retaining ring 23 and the groove 14, which makes assembly convenient.

[0038] An annular upper connecting clip 11 is provided on the top side of the upper cover 1. In this embodiment, the upper connecting clip is an annular edge. An annular protective groove 13 is recessed at the position of the upper connecting clip 11 opposite to the upper edge of the base 2. The protective groove 13 is U-shaped, and the upper edge of the base 2 is located in the protective groove 13. The protective groove 13 is provided to protect the upper edge of the base 2 and prevent deformation and wear of the upper edge of the base 2.

[0039] The base 2 has two opposing perforated slots 21 on its top, each containing a lower elastic clip 22. The lower elastic clip 22 engages with the upper connecting clip 11 to secure the novel snap-on infrared sensor housing to an external component (such as a lampshade, lamp housing, or other component requiring sensor mounting). During engagement, the external component presses against the lower elastic clip 22 to engage between the upper connecting clip 11 and the lower elastic clip 22. The lower elastic clip 22 is a pressable and deformable clip to facilitate the engagement of the external component.

[0040] The lower elastic locking member 22 includes an elastic guide surface at the bottom and an elastic abutment surface at the top. The elastic guide surface and the elastic abutment surface are connected at an angle to form a dihedral structure, and the included angle of this dihedral structure is a protruding locking head. In this embodiment, the locking head is a pointed structure, and both the elastic guide surface and the elastic abutment surface are inclined planes. The elastic abutment surface is inclined upward and inward relative to the locking head and can be pressed downward; the elastic guide surface is inclined downward and inward relative to the locking head and can be pressed upward and inward. The lower end of the elastic guide surface is connected to the lower edge of the hollow groove 21.

[0041] The locking head protrudes from the outermost side of the lower elastic locking member. When assembling with the outer component, the housing body is inserted into the connection port of the outer component from top to bottom. The side wall of the connection port is assembled onto the elastic abutment surface along the elastic guide surface. During the assembly process, the side wall of the connection port squeezes the elastic guide surface so that the locking head is locked below the side wall of the connection port. The side wall of the connection port abuts against the elastic abutment surface and is locked between the upper connecting member 11 and the elastic abutment surface.

[0042] The elastic abutment surface can be pressed downwards, so the distance between the elastic abutment surface and the upper connecting clip 11 can be adjusted to accommodate external parts with different sidewall thicknesses at the connection port.

[0043] Moreover, the side wall of the connection port of the outer component can be pressed against any position of the elastic contact surface. As long as the clip head is pressed against the lower part of the side wall of the connection port, the new type of snap-on infrared sensing shell and the outer component can be snapped together, which is highly versatile.

[0044] Multiple support blocks 25 are provided on the inner bottom of the base 2, and the circuit board can be placed on the support blocks 25. A body through hole 24 is provided on the bottom of the base 2, and the bottom port of the circuit board 3 can protrude from the body through hole 24. An assembly positioning groove 26 is provided on the bottom of the housing body. During automated installation, the assembly positioning groove 26 enables the machine to accurately judge the real-time posture of the new buckle infrared sensing housing, thereby facilitating automated installation.

[0045] Reference Figures 5 to 6 Another embodiment of the novel snap-fit ​​infrared sensing housing of this utility model is proposed:

[0046] A novel snap-fit ​​infrared sensing housing includes a housing body 4, which is integrally formed.

[0047] A Fresnel lens 12 is disposed at the top center of the housing body 4. An annular upper connecting clip 11 is disposed at the top side of the housing body 4. Hollow slots 21 are disposed on opposite sides of the housing body 4 at the bottom of the upper connecting clip 11. Lower elastic clips 22 are disposed within the hollow slots 21. Through the cooperation of the lower elastic clips 22 and the upper connecting clip 11, the novel snap-on infrared sensor housing can be snapped onto an external component (such as a lampshade, lamp housing, or other component requiring sensor installation). During snapping, the external component presses against the lower elastic clip 22 to engage between the upper connecting clip 11 and the lower elastic clip 22. The lower elastic clip 22 is a pressable and deformable clip to facilitate the engagement of the external component.

[0048] The lower elastic locking member 22 includes an elastic guide surface at the bottom and an elastic abutment surface at the top. The elastic guide surface and the elastic abutment surface are connected at an angle to form a dihedral structure, and the included angle of this dihedral structure is a protruding locking head. In this embodiment, the locking head is a pointed structure, and both the elastic guide surface and the elastic abutment surface are inclined planes. The elastic abutment surface is inclined upward and inward relative to the locking head and can be pressed downward; the elastic guide surface is inclined downward and inward relative to the locking head and can be pressed upward and inward. The lower end of the elastic guide surface is connected to the lower edge of the hollow groove 21.

[0049] The connector is inserted into the connection port of the external component. The side wall of the connection port is assembled onto the elastic abutment surface along the elastic guide surface. During the assembly process, the side wall of the connection port squeezes the elastic guide surface so that the clip is locked under the side wall of the connection port. The side wall of the connection port abuts against the elastic abutment surface and is locked between the upper connecting clip 11 and the elastic abutment surface.

[0050] The elastic abutment surface can be pressed downwards, so the distance between the elastic abutment surface and the upper connecting clip 11 can be adjusted to accommodate external parts with different sidewall thicknesses at the connection port.

[0051] Moreover, the side wall of the connection port of the outer component can be pressed against any position of the elastic contact surface. As long as the clip head is pressed against the lower part of the side wall of the connection port, the new type of snap-on infrared sensing shell and the outer component can be snapped together, which is highly versatile.

[0052] The bottom of the housing body 4 is provided with a circuit board entry hole 41. The bottom inner side of the circuit board entry hole 41 is bent inward to form a housing body limiting flange 42. The circuit board can enter through the circuit board entry hole 41 and be secured inside the housing body 4 by the housing body limiting flange 42. An assembly positioning groove 26 is also provided on the bottom of the housing body 4. During automated installation, the assembly positioning groove 26 enables the machine to accurately judge the real-time posture of the new snap-fit ​​infrared sensing housing, thereby facilitating automated installation.
