[0040] See also Figure 1 、 Figure 2 and Figure 3 The first embodiment of the present utility model provides an induction night light, including a body 1 and a sensing element 2. The body 1 includes a light guide cover 11, a light guide plate 12, a reflective film 13, a light-emitting element 14 and a shell 15. A spacer 16 is provided between the light guide cover 11 and the light guide plate 12. The reflective film 13 is provided on the side of the light guide plate 12 away from the light guide cover 11. The light guide cover 11 is exposed from the body 1. The shell 15 is surrounded by the side surfaces of the light guide cover 11, the light guide plate 12 and the reflective film 13, and the body 1 is fastened at the end of the shell 15. The light-emitting element 14 is provided on the inner side wall of the shell 15 and corresponds to the light guide plate 12; the sensing element 2 is located in the center of the body 1, and the working end of the sensing element 2 passes through the reflective film 13, the light guide plate 12 and the light guide cover 11 in sequence and then is exposed.
[0041] The light guide 11 is arranged at the center of the body 1, and the sensing center of the sensing element 2 coincides with the center of the sensing night light, so that the sensing range is evenly spread around the sensing night light, thereby improving the sensing accuracy of the sensing element 2 and facilitating the user to turn the body 1 on or off at any time.
[0042] Furthermore, a first mounting hole 111, a second mounting hole 121, and a third mounting hole 131 are respectively defined in the centers of the light guide 11, the light guide plate 12, and the reflective film 13. The sensor 2 passes through the first mounting hole 111, the second mounting hole 121, and the third mounting hole 131, respectively, and is exposed at the first mounting hole 111. The sensor 2 is sequentially connected to the light guide 11, the light guide plate 12, and the reflective film 13 at the center of the body 1, thereby improving the stability of the connection structure between the sensor 2 and the body 1 and allowing the sensor 2 to be exposed at the first mounting hole 111 in the center of the body 1, making it easier for the user to trigger the sensor 2.
[0043] Preferably, the sensing range of the sensing element 2 coincides with the irradiation range of the body 1 , and the sensing element 2 is triggered when the user moves within the irradiation range, thereby reducing the risk of accidentally touching the sensing element 2 .
[0044] See also Figure 2 and Figure 3 It can be understood that the light-emitting component 14 is connected to the inner wall of the shell 15 and corresponds to the outer wall of the light guide plate 12. The light-emitting range of the light-emitting component 14 is greater than the thickness of the light guide plate 12, so that the light of the light-emitting component 14 can cover the outer wall of the light guide plate 12, further improving the uniformity of the light source received by the light guide plate 12.
[0045] Furthermore, the light-emitting element 14 is a point light source, and the light-emitting element 14 is evenly distributed in a ring shape on the inner wall of the shell 15, so that the light guide plate 12 can evenly receive the light of the point light source light-emitting element 14 and convert it into a surface light source, avoiding the situation where the light on the surface of the light guide plate 12 cannot be evenly emitted due to uneven distribution of the light-emitting element 14.
[0046] Furthermore, the reflective film 13 is attached to a surface of the light guide plate 12 away from the light guide cover 11 to reflect light from this surface of the light guide plate 12 as much as possible, thereby improving the light transmission effect of the light guide plate 12 .
[0047] Furthermore, the light guide cover 11 abuts against the light guide plate 12 at its edge. By bending the light guide cover 11 to a certain degree of curvature and providing a gap 16 between the light guide plate 12 and the light guide cover 11, there is sufficient space for light on the surface of the light guide plate 12 to be evenly transmitted to the light guide cover 11, and the edge of the light guide cover 11 abuts against the light guide plate 12, ensuring that the light guide cover 11 can evenly receive light.
[0048] Furthermore, the light guide cover 11 is bent toward the light guide plate 12 at the edge near the first mounting hole 111, so that the light guide cover 11 is arc-shaped and is installed in coordination with the vertical circumferential surface of the sensing element 2 to ensure the stability of the connection structure between the light guide cover 11 and the sensing element 2.
[0049] It should be noted that the area of the light guide cover 11 is not larger than that of the light guide plate 12 , so that the light guide cover 11 can evenly emit the light transmitted by the light guide plate 12 and utilize all parts of the light guide cover 11 to emit light as much as possible.
[0050] Furthermore, a step structure 112 is provided around the edge of the light guide cover 11, and a protrusion 151 is provided correspondingly at the end of the shell 15. The step structure 112 is engaged with the protrusion 151 and is fastened to each level of connection structure in the main body 1 in a direction away from the protrusion 151 through the protrusion 151. The provision of the protrusion 151 can make the connection structure between the shell 15 and the light guide cover 11 more stable, and the shell 15 can be more firmly installed in the main body 1.
[0051] Specifically, the main body 1 also includes a chassis 17, which is connected to the side of the reflective film 13 away from the light guide cover 11 and is used to achieve connection with the external plane. The chassis 17 protects the internal components of the main body 1 and extends the service life of the induction night light; and the connection structure between the chassis 17 and the external plane is set to a detachable connection structure, so that the main body 1 can be detachably connected to the external plane through the chassis 17, which is convenient for users to flexibly set the position of the induction night light.
[0052] Optionally, the chassis 17 can be connected to an external plane by magnetic connection or adhesive connection, so that the user can adjust the position of the sensor night light at any time to enhance the user experience.
[0053] It should be noted that an annular convex rail 172 is provided on the outer wall of the chassis 17 , and a corresponding annular groove 152 is formed on the inner wall of the shell 15 . The annular convex rail 172 is installed in the annular groove 152 , so that the chassis 17 and the shell 15 are stably connected.
[0054] Furthermore, the main body 1 also includes a main control circuit board 18, which is mounted on the chassis 17. The main circuit board 18 is at least partially exposed in the first mounting hole 111, the second mounting hole 121, and the third mounting hole 131, and is electrically connected to the sensor 2 through the third mounting hole 131. The main control circuit board 18 can control the working state of the sensor 2 and control the switching and working state of the entire sensor night light when the user triggers the sensor 2.
[0055] Furthermore, a support frame 171 is provided on one side of the chassis 17 close to the reflective film 13, and the main control circuit board 18 is mounted on the support frame 171. The support frame 171 provides a certain height for the main control circuit board 18 so that the main control circuit board 18 can be electrically connected to the sensor 2.
[0056] Furthermore, the support frame 171 and the edge ends of the chassis 17 are at the same height so as to jointly support the reflective film 13 and the light guide plate 12 and improve the stability of the overall structure.
[0057] Furthermore, the body 1 includes a side circuit board 19. One side of the side circuit board 19 is flexibly attached to the inner wall of the housing 15, and the other side is connected to the light-emitting element 14. The side circuit board 19 is electrically connected to the light-emitting element 14 and the main control circuit board 18. The light-emitting element 14 is fixed to the housing 15 via the side circuit board 19, and the main control circuit board 18 can control the operating state of the light-emitting element 14 through the side circuit board 19.
[0058] See also Figure 2 and Figure 5 The main body 1 includes a switch 113, which is exposed on the shell 15 and electrically connected to the main control circuit board 18. The user can control the main control circuit board 18 through the switch 113, and then control the overall on and off state of the induction night light.
[0059] Furthermore, the main body 1 also includes a battery 110 and an interface 114. The battery 110 is installed on the support frame 171, and the interface 114 is electrically connected to the battery 110 through the main control circuit board 18. The power supply can be connected through the interface 114 to power the entire induction night light, or the battery 110 can be charged through the interface 114. The battery 110 supports the operation of the induction night light by supplying power to the main control circuit board 18, and the user can change the position of the induction night light at any time for easy use.
[0060] Furthermore, the main body 1 also includes an indicator light 115, which is exposed on the shell 15 and electrically connected to the main control circuit board 18. The indicator light 115 can display the working status of the induction night light or issue prompts to the user to enhance the user experience.
[0061] In summary, please refer to Figures 1 to 5 The working principle of the induction night light provided by this utility model is as follows:
[0062] The main control circuit board 18 controls the operation of the light-emitting elements 14 through the side circuit board 19. When the evenly arranged light-emitting elements 14 emit light, the light can be evenly transmitted to the light guide plate 12. Under the action of the reflective film 13 and the spacer 16, the light is evenly transmitted from the surface of the light guide plate 12 to the light guide cover 11, and all parts of the light guide cover 11 are used as much as possible to output the light evenly, while expanding the illumination range to avoid the appearance of obvious light spots.
