[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example

[0037] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a night light with a voice-activated quick-reset structure includes a base 1. The base has a cavity with an opening at the top. A cover 2 is fixed to the top of the base by screws. A control circuit board 3 and a power supply 4 connected to the control circuit board are disposed within the base. The control circuit board has a conventional structure from the prior art, simply applied. The power supply is a battery. The base has a charging port 5 and a switch 23. Charging can be performed through the charging port. In this embodiment, the base is rectangular, but in practical applications, other common shapes are also possible.

[0038] In this embodiment, the upper part of one side wall of the base has a recessed groove 6 communicating with the cavity; and a telescopic rack 7 is provided inside the base, the outer end of the telescopic rack passing through the recessed groove and extending out of the outer side of the base, and a light source 8 is fixed to the outer end of the telescopic rack; the width of the telescopic rack matches the width of the recessed groove, and the thickness of the telescopic rack matches the height of the recessed groove. In actual application, an L-shaped support 9 is integrally formed on the outer end of the telescopic rack, the light source is fixed on the top surface of the horizontal part of the L-shaped support, and a light-transmitting cover 10 is provided on the outer side of the light source. The light-transmitting cover is a hemispherical light-transmitting cover, and the height of the L-shaped support can be processed and set as needed;

[0039] In this embodiment, the base is equipped with a motor mount 11 and a quick-return control structure 12, and the motor mount is connected to the quick-return control structure. A quick-reset structure 13 is fixed between the telescopic rack and the inner wall of the base. In actual application, a drive motor 14 is fixed on the motor mount, and a drive gear 15 that meshes with the telescopic rack is fixed on the main shaft of the drive motor. The drive motor can drive the telescopic rack to move horizontally by rotating the drive gear. A sound control module 16 is provided on the base, and the sound control module, the light source, the drive motor, and the quick-return control structure are all connected to the control circuit board. The quick-reset structure is a telescopic spring. When the drive gear separates from the telescopic rack, the elastic force of the telescopic spring causes the telescopic rack to quickly retract and reset. The sound control module includes a sound control microphone, which is connected to the control circuit board. A strip-shaped groove 22 is provided on the top surface of the telescopic rack. The telescopic spring and the spiral wire of the light source are both located in the strip-shaped groove. This can prevent the telescopic spring from tilting or shaking.

[0040] The voice control module receives a signal and controls the rapid retraction control structure to move the motor base so that the drive gear separates from the telescopic rack, and the rapid reset structure makes the telescopic rack quickly reset.

[0041] In this embodiment, an eccentric annular protrusion 17 is integrally formed on the outer wall of the motor base, and a locking protrusion 18 is fixed on the inner wall of the eccentric annular protrusion. The rapid retraction control structure includes a rapid retraction control motor 121, a rotating shaft 122 fixed on the main shaft of the rapid retraction control motor, a rapid retraction trigger plate 123 fixed at the end of the rotating shaft, a lever 124 fixed on the edge of the rapid retraction trigger plate, and a spring 125 sleeved on the rotating shaft, with both ends of the spring abutting against the end face of the rotating shaft and the side of the rapid retraction trigger plate. The rapid retraction trigger plate is located inside the eccentric annular protrusion. The motor base can be connected to the inner wall of the base via a shaft protrusion. When the rapid retraction control motor rotates, the lever abuts against the locking protrusion and drives the motor base downwards away from the telescopic rack, causing the drive gear to separate from the telescopic rack. When the rapid retraction control motor rotates, the lever rotates within the eccentric annular protrusion, causing the motor base to move up and down slightly, thereby achieving separation or re-engagement of the drive gear and the telescopic rack.

[0042] In this embodiment, the emergency retraction control motor is fixed to the inner wall of the base by a motor fixing piece 19. This ensures the stability and reliability of the emergency retraction control motor installation. Furthermore, two Hall sensors 20 for travel limit are provided on the inner wall of the base along the translational direction of the telescopic rack. The two Hall sensors correspond to the maximum extension position and the retracted origin position of the telescopic rack, respectively, and both Hall sensors are connected to the control circuit board.

[0043] In this embodiment, a light-transmitting decorative panel 21 is fixed to the top of the vertical part of the L-shaped support with screws; and the light from the light source shines outward through the light-transmitting decorative panel. This can improve the lighting effect. The light-transmitting decorative panel can be various graphics and texts, and can also be sprayed with different patterns.

[0044] Compared with the prior art, this utility model has the following positive effects: This utility model includes a motor base, an emergency retraction control structure, a quick reset structure, a voice control module, a drive motor, a drive gear, and a telescopic rack. A light source is fixed at the outer end of the telescopic rack. The drive motor and drive gear can drive the telescopic rack to extend and retract, changing the position of the light source to achieve a dynamic lighting effect. The voice control module triggers the emergency retraction control structure to separate the drive gear from the telescopic rack, and the quick reset structure causes the telescopic rack to quickly retract and reset. The reset response is fast, and the drive gear and telescopic rack disengage smoothly without jamming. This enhances the overall structure's appeal and can meet the usage needs of different scenarios, solving the technical shortcomings of existing nightlights where limited usability restricts their application scenarios.

[0045] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
