The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0048] After the night light product is produced, the positional relationship between the power pin and the main structure is fixed. Therefore, when the power pin is plugged into the socket, the lighting direction of the night light is also fixed and cannot be adjusted. For sockets in some special locations, such as when the socket is below the area where people are active and the night light is emitting light upward, part of the light emitted by the night light will directly enter the human eye, causing eye discomfort. For example, when the socket is located at a corner near a wall and the night light is large in size, the power pin of the night light will not be able to be inserted into the socket due to structural interference between the main body of the night light and the adjacent wall.

[0049] In this regard, the embodiment of the present application proposes a night light, which adopts a columnar main body and has a connection hole on the side of the main body. The connection hole is used to rotate with a rotating seat and a limiter installed with a power pin, so that the power pin and the main body can rotate relative to each other, so that after the power pin is inserted into the socket, the main body can be easily rotated to adjust the light direction. At least one end of the main body is set as a light-emitting part, so that when the power pin is connected to the socket on the wall, the night light emits light in a direction parallel to the wall, and does not emit light to the user activity area of ​​the night light away from the wall, so that the light generally does not directly enter the human eye, which effectively protects the human eye.

[0050] The night light provided in this embodiment can rotate the main body to make the light-emitting area face left, right or downward to avoid facing the eyes directly when the socket is located below the people's activity area mentioned above. When the socket is located at a corner close to the wall, the columnar main body can be rotated to a vertical state to avoid interference with the adjacent wall on the left or right side, so that the night light can be normally plugged into the socket for lighting.

[0051] First see Figure 1 and Figure 2 , Figure 1 The three-dimensional structure of the night light is shown. Figure 2The exploded structure of the night light is shown in the figure. As shown in the figure, the night light 100 includes: a main body 110, a circuit board 120, a light-emitting component 130 and a pin assembly 140. The main body 110 is columnar, and a light guide 111 is provided at at least one end of the main body 110, and a connecting hole 112 is provided on one side of the main body 110. The circuit board 120 is arranged inside the main body 110. The light-emitting component 130 is arranged inside the main body 110 and facing the light guide 111, and the light-emitting component 130 is electrically connected to the circuit board 120. The pin assembly 140 includes: a rotating seat 141, a limit member 142 and a power pin 143. The rotating seat 141 can be rotatably inserted into the connecting hole 112 and abut against the outer wall of the main body 110, and the rotation direction is as shown in FIG. Figure 1 As shown by the arc arrow in the middle, the stopper 142 is disposed inside the main body 110, and the stopper 142 is fixedly connected to the inward end of the rotating seat 141, and abuts against the inner wall of the main body 110 located around the connecting hole 112 to limit the rotating seat 141 from rotating along the axial direction of the connecting hole 112 ( Figure 2 The power pin 143 is fixed to the outward end of the rotating base 141 and is electrically connected to the circuit board 120. The power pin 143 is used to be plugged into a socket (not shown) to supply power to the circuit board 120 so that the light-emitting element 130 emits light.

[0052] The main body 110 is the main structure of the night light 100, including a shell and a mounting structure for assembling other components. The circuit board 120 can be fixed to the studs on the inner wall of the main body 110 by threaded fasteners to achieve assembly and fixation in the main body 110. The light-emitting component 130 can be directly integrated and fixed on the circuit board 120, or it can be fixed to the main body 110 and electrically connected to the circuit board 120 through a wire. The light-emitting component 130 can be an LED lamp, etc. The light guide 111 can be a PC light guide column (polycarbonate material light guide column). The light emitted by the light-emitting component 130 is diffused by the light guide 111 and then dispersed to the outside world to achieve the lighting function.

[0053] For the connection method between the rotating seat 141 and the limiting member 142 and the rotational matching method between the pin assembly 140 and the main body 110, please refer to Figure 2 and Figure 3 ,in Figure 3 FIG. 1 shows a cross-sectional view of the mating portion between the pin assembly 140 and the main body 110. Figure 2 As shown in the figure, the stopper 142 can be in the shape of a plate, and of course, in other embodiments, it can also be in the shape of a block. The stopper 142 is provided with a plurality of through holes 1421, and the inner end of the rotating seat 141 is provided with a threaded hole 1411. A threaded fastener (not shown) passes through the through hole 1421 and is connected to the threaded hole 1411 to assemble and fix the stopper 142 and the rotating seat 141. On this basis, as Figure 3As shown in , after the stopper 142 is assembled and fixed with the rotating seat 141, the rotating seat 141 abuts against the outer wall of the main body 110, and the stopper 142 abuts against the inner wall of the main body 110, so that the entire pin assembly 140 and the main body 110 are fixed to each other along the axial direction of the connecting hole 112, thereby ensuring the structural stability of the pin assembly 140. In addition, the entire pin assembly 140 can rotate relative to the main body 110 to adjust the light emitting direction.

[0054] The night light 100 provided in the embodiment of the present application is designed with a pin assembly 140 that is rotatable relative to the main body 110, so that the light-emitting direction can be adjusted after the night light 100 is plugged into the socket. At the same time, a columnar main body 110 is adopted and a light guide 111 is arranged at at least one end of the main body 110, so that after the night light 100 is connected to the socket on the wall, the light-emitting direction is in a direction parallel to the wall, thereby avoiding emitting light directly towards the user's area, thereby protecting the user's eyes. Specifically, the pin assembly 140 adopts a method of assembling and fixing a rotating seat 141 and a limiting member 142 and matching the main body 110 to achieve rotation relative to the main body 110, wherein the rotating seat 141 passes through the connecting hole 112 on the main body 110 and abuts against the outer wall of the main body 110, and the limiting member 142 is arranged inside the main body 110, fixedly connected to the inward end of the rotating seat 141 and abuts against the inner wall of the main body 110. Such a design can ensure the stability of the overall structure while achieving the relative rotation of the pin assembly 140 and the main body 110, and can make the night light 100 simple in structure, easy to assemble, and low in cost.

[0055] Regarding the manner in which the rotating seat 141 abuts against the outer wall of the main body 110, the present application further proposes an embodiment. Figure 2 and Figure 4 ,in Figure 4 The exploded structure of the night light from another perspective is shown. As shown in the figure, the outer wall of the main body 110 located around the connecting hole 112 is provided with an annular protrusion 113, and the outer wall around the annular protrusion 113 is provided with an annular limiting wall 114, and a guide groove 115 is formed between the protrusion 113 and the limiting wall 114. The rotating seat 141 includes a rotating shaft 1412 and a mounting plate 1413. The rotating shaft 1412 can be rotatably inserted into the connecting hole 112, and the inward end of the rotating shaft 1412 is fixedly connected to the limiting member 142. The mounting plate 1413 is arranged at the outward end of the rotating shaft 1412, and the power pin 143 is fixed to the mounting plate 1413. The edge of the mounting plate 1413 extends toward the main body 110 to form a plug-in wall 1414, and at least part of the plug-in wall 1414 can be rotatably inserted into the guide groove 115.

[0056] Specifically, the protrusion 113 and the limiting wall 114 can be integrally formed with the main body 110, and of course can also be assembled and fixed by means of hot melting, snap-fitting, threaded connection, etc. Similarly, the rotating shaft 1412, the mounting plate 1413 and the plug-in wall 1414 can be integrally formed or assembled and fixed by means of hot melting, snap-fitting, threaded connection, etc.

[0057] After the plug-in wall 1414 is at least partially inserted into the guide groove 115 and forms a rotational fit with the guide groove 115, it can play a good guiding role in the rotation of the rotating seat 141 to ensure the accuracy of the rotation. At the same time, the limiting wall 114 is covered on the outer periphery of the plug-in wall 1414. On the one hand, it can make the night light 100 as a whole simple and beautiful, and on the other hand, it can provide reliable protection for the rotating seat 141.

[0058] Considering that the power pin 143 and the circuit board 120 need to be electrically connected through wires, if the rotation angle of the rotating base 141 is too large, the wires may be over-entangled and thus break. Based on this, the present application further proposes an implementation method, please continue to refer to Figure 2 and Figure 4 As shown in the figure, a limiting plate 116 is arranged in the guide groove 115, and the plug-in wall 1414 includes an annular first portion 14141 and a semi-annular second portion 14142, wherein the first portion 14141 is located between the second portion 14142 and the mounting plate 1413. The first portion 14141 can be rotatably received in the limiting wall 114, and the second portion 14142 can be rotatably inserted in the guide groove 115, and the two ends of the second portion 14142 along the circumference thereof are used to abut against the limiting plate 116 when the pin assembly 140 rotates relative to the main body 110, so as to limit the rotation stroke of the pin assembly 140.

[0059] Specifically, see Figures 5 to 7 ,like Figure 5 As shown in , when the distances between the two ends of the second portion 14142 and the limiting plate 116 are equal, both being a quarter arc, after the power pin 143 is inserted into the socket, the main body 110 is in a vertical state. Figure 5 On the basis of the pin assembly 140, after the pin assembly 140 is rotated 90° counterclockwise, the free end of the second portion 14142 located at the bottom abuts against the limiting plate 116, forming a Figure 6 In the state shown, after the power pin 143 is inserted into the socket, the main body 110 is in a horizontal state. Figure 5 On the basis of the pin assembly 140, after the pin assembly 140 is rotated 90° clockwise, the free end of the second portion 14142 located at the top abuts against the limiting plate 116, forming a Figure 7 In the state shown, after the power pin 143 is inserted into the socket, the main body 110 is in the same Figure 6 Opposite horizontal direction.

[0060] In this embodiment, after the limiting plate 116 is arranged in the guide groove 115, the limiting plate 116 and the semi-circular second portion 14142 on the plugging wall 1414 abut against the limiting plate 116 to limit the rotation angle of the pin assembly 140, thereby preventing the pin assembly 140 from rotating excessively and causing the wire between the power pin 143 and the circuit board 120 to break. At the same time, by receiving the annular first portion 14141 on the plugging wall 1414 inside the limiting wall 114, the plugging wall 1414 and the limiting wall 114 form a tight fit, thereby improving the stability of the rotation fit between the pin assembly 140 and the main body 110.

[0061] Regarding the wiring between the power pin 143 and the circuit board 120, the present application further proposes an implementation method, which can be found in Figure 8 The figure shows the structure of the pin assembly 140. As shown in the figure, a wiring groove 14121 is provided on the side wall of the rotating shaft 1412. The wiring groove 14121 is connected to the inward end of the rotating shaft 1412. A wire passing hole 1422 is provided on the position opposite to the wiring groove 14121 on the limiting member 142. The wire (not shown) connected to the power pin 143 passes through the wiring groove 14121 and the wire passing hole 1422 in turn into the interior of the main body 110 and is connected to the circuit board 120.

[0062] After opening a wiring groove 14121 on the side wall of the rotating shaft 1412 and a wire hole 1422 on the limiting member 142, the wire connected between the power pin 143 and the circuit board 120 can be limited to ensure that the wire will not interfere with or get entangled with other structures during the rotation of the pin assembly 140, thereby ensuring the stability of the operation of the night light 100.

[0063] In actual operation, the user generally inserts the power pin 143 into the socket first, and then rotates the main body 110 to make the main body 110 and the pin assembly 140 rotate relative to each other. Considering that the structural strength of the connection between the rotating shaft 1412 and the mounting plate 1413 is relatively weak, when stress is generated between the main body 110 and the rotating shaft 1412 due to manufacturing and assembly errors, friction will be generated between the main body 110 and the rotating shaft 1412 during the rotation of the main body 110. The friction will act on the rotating shaft 1412 to generate torque. When the torque is large, it will cause cracks between the rotating shaft 1412 and the mounting plate 1413.

[0064] Based on the above problems, this application further proposes an implementation method. Please refer to Figure 8As shown in the figure, a plurality of reinforcing ribs 144 are evenly arranged along the circumferential direction between the side wall of the rotating shaft 1412 and the mounting plate 1413. This arrangement can improve the structural strength of the connection between the rotating shaft 1412 and the mounting plate 1413, thereby improving the torsional strength of the rotating shaft 1412 and the mounting plate 1413 as a whole.

[0065] Considering that after the reinforcement rib 144 is provided, the reinforcement rib 144 will contact the outer wall of the main body 110 at the edge of the connecting hole 112 and generate friction. In order to reduce the friction, the present application further proposes an implementation method. For details, please refer to Figure 2 As shown in the figure, a gasket 145 is provided between the reinforcing rib 144 and the outer wall of the main body 110 , the gasket 145 is sleeved on the rotating shaft 1412 , and the gasket 145 has a smooth surface.

[0066] By providing a gasket 145 with a smooth surface between the reinforcing rib 144 and the inner wall of the main body 110 , the friction between the reinforcing rib 144 and the outer wall of the main body 110 can be reduced when the rotating shaft 1412 rotates, thereby ensuring the flexibility of the rotating shaft 1412 .

[0067] Please refer again Figure 1 As shown in the figure, in some embodiments, at least one end of the main body 110 is provided with a stepped groove 117 , and the light guide 111 is disposed at the bottom of the groove 117 .

[0068] The stepped groove 117 can limit the light emitted from the bottom light guide 111 to a certain extent, so that more light is emitted in the direction of the end surface, avoiding the light from being scattered at a large angle and entering the human eye, thereby protecting the human eye to a certain extent. At the same time, the stepped groove 117 makes the appearance of the main body 110 more layered and beautiful.

[0069] In order to improve the lighting effect, this application also proposes an implementation method. Please refer to Figure 2 As shown in the figure, a reflector 150 is disposed inside the main body 110 . The reflector 150 is disposed on the outer periphery of the light emitting element 130 . The reflector 150 is used to reflect the light emitted by the light emitting element 130 to the light guide 111 .

[0070] Specifically, the reflector can be an existing reflector, such as a plastic reflector, a glass reflector, a metal reflector, etc. The reflector 150 reflects the light emitted by the light emitting element 130 onto the light guide 111, so that more light can be diffused from the light guide 111 to the outside, thereby improving the illumination brightness of the night light 100.

[0071] See also Fig. 9, the figure shows the exploded structure of the night light 100. As shown in the figure, in some embodiments, a sensing component 160 is disposed inside the main body 110, and the sensing component 160 faces the direction away from the side of the pin component 140. A light-transmitting member 170 is embedded on the side wall of the main body 110 at a position opposite to the sensing component 160. The sensing component 160 is electrically connected to the circuit board 120, and is used to trigger the light-emitting member 130 to emit light when a target is detected.

[0072] Specifically, the sensing component 160 may be a passive infrared sensor (PIR sensor for short). When the PIR sensor detects a target with temperature (such as a person or an animal), it can generate an electrical signal to trigger the light-emitting element 130 to emit light.

[0073] The light-transmitting element 170 may be a Fresnel lens, which may limit the frequency peak of the incident light to a specific wavelength, such as the peak value of infrared radiation of the human body, thereby improving the detection accuracy and sensitivity of the sensing component 160 .

[0074] By setting the sensing component 160 in a direction away from the pin component 140, so that its sensing range is in the area where the user is active, when the night light 100 works at night, the light-emitting component 130 does not emit light in the default state, thereby not affecting the user's sleep and rest at night. When the user gets up at night and passes through the detection area of ​​the sensing component 160, the sensing component 160 senses the user and triggers the light-emitting component 130 to emit light, thereby providing timely night lighting for the user. When the sensing component 160 does not detect the user for a certain period of time, the light-emitting component 130 can be automatically turned off to ensure that the user's sleep and rest are not affected.

[0075] Furthermore, if Fig. 9 As shown in FIG. 1 , the light-transmitting member 170 is in the shape of a strip having an arc, and the outer surface of the light-transmitting member 170 is flush with the outer wall of the main body 110. This arrangement can make the surface of the night light 100 neat and beautiful.

[0076] Please refer again Figure 2 and Figure 4 , and further combined with Fig.10 , Fig.10The modular circuit structure is shown in the figure. As shown in the figure, light guides 111 are provided at both ends of the main body 110, and the light-emitting element 130 is provided with multiple light guides 111 corresponding to the two ends. A controller 180 is provided on the circuit board 120, and the controller 180 is electrically connected to the light-emitting element 130 and the power pin 143 respectively. The power pin 143 is used to supply power to the controller 180. It should be noted that the working voltage of the controller 180 is generally much lower than the voltage provided by the socket. Therefore, a buck and a rectifier are generally provided between the power pin 143 and the controller 180 on the circuit board 120 to provide the controller 180 with the voltage input from the power pin 143 after bucking and rectifying. The side wall of the main body 110 is provided with a plurality of light guides 111 along its axial direction ( Figure 4 The toggle switch 191 is electrically connected to the controller 180. The toggle switch 191 has three gears arranged along the axial direction of the main body 110. When the toggle switch 191 is toggled to the middle gear, the controller 180 is triggered to control the light-emitting elements 130 at both ends to emit light. The toggle switch 191 is also used to trigger the controller 180 to control the light-emitting element 130 at the end closer to the gear to emit light when it is toggled to one of the gears at the two ends. Fig.10 The correspondence between the dotted arrow and the light indicated by the dotted line, and the correspondence between the solid arrow and the light indicated by the solid line.

[0077] The toggle switch 191 may be an existing electronic switch, and the circuit structure in which the toggle switch 191 triggers the controller 180 to control the corresponding light-emitting element 130 to emit light is implemented using an existing circuit structure.

[0078] This embodiment utilizes the property that both ends of the main body 110 can emit light, and sets a toggle switch 191 on the main body 110 that slides along its axial direction, and configures the toggle switch 191 so that when it is in the middle position, both ends of the main body 110 emit light, and when the toggle switch 191 is toggled from the middle position to one end position, the end indicated by the toggle direction emits light, and the other end does not emit light. Such a design allows users to adjust the specific lighting mode according to their own needs, and the adjustment mode is easy to remember and operate, while also improving the playability of the night light 100.

[0079] For further information, see Fig. 9 In some embodiments, a light intensity detector (not shown) is disposed inside the main body 110, and the light intensity detector is electrically connected to the controller 180. A detection port 192 for the light intensity detector to detect is opened on the side wall of the main body 110. The light intensity detector is used to trigger the controller 180 to control the light-emitting element 130 to emit light when it detects that the external light intensity becomes weaker.

[0080] Please continue reading Fig. 9In some embodiments, a brightness adjustment button 193 is further provided on the main body 110 , and the brightness adjustment button 193 is electrically connected to the controller 180 for adjusting the luminous intensity of the light-emitting element 130 .

[0081] Please continue reading Fig. 9 In some embodiments, the main body 110 is further provided with a mode switch 194, which is electrically connected to the controller 180 and is used to switch the working mode of the night light 100. Specifically, the mode switch 194 can be a toggle switch, which can switch the night light 100 to a normally closed mode (the light emitting element 130 does not emit light), a normally open mode (the light emitting element 130 is always on), and an automatic mode (when the light intensity detector detects that the external light intensity is weakened and the sensing component 160 senses the target, the controller 180 is triggered to control the light emitting element 130 to emit light).
