[0002] Induction lamps are a new type of intelligent lighting product that automatically controls the lighting of light sources or adjusts the brightness of light through induction modules. For example, a Chinese utility model patent with the authorization announcement number CN 213066048 U discloses a plug-in lamp sensor and a lamp. The plug-in lamp sensor includes a sensor housing and a connector provided on one side of the sensor housing. The front end of the connector is snap-fitted with the sensor housing through a first buckle, and the rear end of the connector is provided with an external thread and a fastening nut, and is connected to the lamp through the cooperation of the external thread and the fastening nut. The above-mentioned plug-in lamp sensor is fixedly installed on the lamp through the external thread and the fastening nut on the connector.

[0003] In order to simplify the installation process between the sensor and the lamp, a Chinese utility model patent with the authorization announcement number CN 219627007 U discloses a technical solution of connecting the sensor and the lamp using a USB interface.

[0004] However, the interface of the USB base is small, and the interface of the USB base on the lamp often has a certain depth, or the interface of the USB base is partially / wholly blocked by other structures, and the lamp is usually installed on a higher ceiling. Therefore, when the sensor is plugged into the lamp, the human eye cannot observe the relative position of the USB plug on the sensor and the USB base on the lamp in real time. The USB plug can easily hit the metal ring of the female interface on the USB base, thereby easily pushing out the USB base on the lamp and damaging the structure of the lamp. Utility Model Content

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 8 The figure shows a preferred embodiment of the USB base 100 of the utility model. The USB base 100 is installed on the lamp frame 301 of the lamp 300 and can be plugged into the sensor 200 with a USB plug 204. When the lamp 300 needs the sensing function, the sensor 200 is plugged in, and when the lamp 300 does not need the sensing function, the sensor 200 can be unplugged. Moreover, the USB interface is a universal interface, and one sensor 200 can be plugged into multiple lamps 300 to improve the utilization rate of the sensor 200.

[0031] like Figure 5 , 6As shown, the USB base 100 comprises a USB interface 1, a base body 2 and a cover body 3. The USB interface 1 is a female interface, and the USB interface 1 is provided with a female interface metal ring 11.

[0032] Specifically, a chamber 2a is provided inside the base body 2, and the chamber 2a has an upper opening 21 and a lower opening 22. A USB interface 1 is placed in the chamber 2a, and the opening end of the USB interface 1 faces the upper opening 21 for plugging with a USB plug 204.

The bottom cover 31 covers the lower opening 22 of the chamber 2a to prevent the USB interface 1 from slipping out of the chamber 2a. The two connecting arms 32 are clamped in the above-mentioned connecting slots 23 to achieve the connection between the base body 2 and the cover body 3; in addition, the upper edge of the connecting arm 32 is provided with a first flange 321 extending outward.

[0034] like Figure 5 , 8 As shown, a clearance groove 212 is formed on the second flange 211 on the base 2, and the first flange 321 on the connecting arm 32 is located in the clearance groove 212, and the lower edges of the first flange 321 and the second flange 211 are flush; when the USB base 100 is installed on the lamp frame 301 of the lamp 300, the lower edges of the first flange 321 and the second flange 211 are in contact with the upper surface of the lamp frame 301; when the sensor 200 is inserted into the USB base 100, the USB plug 204 on the sensor 200 is mistakenly pushed against the female interface metal ring 11 on the USB base 100, and due to the interaction between the lamp frame 301 and the first flange 321, the lamp frame 301 can resist the USB base 100 to prevent the USB base 100 from being pushed out of the lamp 300.

[0035] In order to improve the firmness of the connection between the base body 2 and the cover body 3 , two positioning protrusions 322 extending to the left and right are provided on the connecting arm 32 , and correspondingly, two positioning grooves 231 for engaging the positioning protrusions 322 are provided in the connecting slot 23 .

[0036] like Figures 5 to 8As shown, in this embodiment, the bottom of the USB interface 1 is fixedly connected with a PCB board 4, the area of ​​the PCB board 4 is larger than the area of ​​the lower opening 22 of the chamber 2a, the USB interface 1 is located in the chamber 2a, and the PCB board 4 is located outside the chamber 2a; when the seat 2 is connected to the cover 3, part of the upper end surface of the PCB board 4 abuts against the seat 2, part of the lower end surface of the PCB board 4 abuts against the bottom cover 31 of the cover 3, and the two opposite outer side walls of the PCB board 4 abut against the inner side walls of the two connecting arms 32 respectively, that is, the PCB board 4 is located in the gap between the seat 2 and the cover 3 after the two are connected. Since the PCB board 4 cannot move at will, the USB interface 1 is also fixed in the chamber 2a. In addition, the PCB board 4 is connected with a wire 5 connected to the lamp 300, and the bottom cover 31 is provided with a notch 311 for the wire 5 to pass through; the upper opening 21 of the chamber 2a is also covered with a first silicone plug 6, and the first silicone plug 6 is used to prevent dust or foreign matter from entering the USB interface 1.

[0037] The assembly process of the USB base 100 in this embodiment is as follows: the USB interface 1, the PCB board 4 and the wire 5 are pre-assembled as an integrated part, and the above-mentioned integrated part is placed from the lower opening 22 of the cavity 2a, and then the wire 5 is passed through the notch 311 on the bottom cover 31, and at the same time, the two connecting arms 32 on the cover body 3 are slightly opened and clamped in the connecting slot 23 of the base body 2.

[0038] like Figure 1 , 2 As shown in FIGS. 7 and 8, the utility model also protects a lamp 300 equipped with the USB base 100. A mounting hole 302 is provided on a lamp frame 301 of the lamp 300. The USB base 100 is snapped into the mounting hole 302 through a buckle 24. The USB base 100 can be connected to a sensor 200 with a USB plug 204. The USB base 100 on the lamp 300 can be used to connect the sensor 200, and can also be used to connect other components.

[0039] like Figures 2 to 4 As shown, in order to prevent the sensor 200 from falling off the lamp frame 301, a first threaded hole 201 is provided on the sensor 200, and a second threaded hole 303 is provided on the lamp frame 301. The screw 202 passes through the first threaded hole 201 and the second threaded hole 303 to connect the sensor 200 to the lamp frame 301; after the sensor 200 is threadedly connected to the lamp frame 301, a second silicone plug 203 is covered in the first threaded hole 201.
