[0039] The embodiment is shown in Figures 1 to 5 As shown, a liftable decorative night light includes an outer box 1 provided with a concave cavity, and an outer cover 3 rotatably connected to the opening of the outer box through a movable shaft 2. In this embodiment, both the outer cover and the outer box are plastic structures, and the outer cover can rotate around the movable shaft to open or automatically close under the action of gravity.

[0040] Moreover, in this embodiment, a support 4 is fixed in the concave cavity. Two support columns 5 are provided on the symmetric edges of the top surface of the support, and a lifting guide groove 6 is formed between the two support columns; the support is a plastic structure or a metal structure, and can be fixed by screws or by using a snap-fastening method. The width of the lifting guide groove between the support columns can be processed and set as needed, mainly for lifting guidance to prevent tilting or displacement during lifting, and to ensure the smoothness and reliability of lifting.

[0041] In this embodiment, a rack column 7 with a tooth groove on the side is fixed on the top surface of the support; the position of the rack column can be set as needed, and it is parallel to the support column, mainly to ensure the effectiveness and smoothness of lifting. And the top end of the support column is fixed with a light source structure 8; the light source structure includes a light source base and a lamp bead chip fixed on the light source base, and its light irradiates outward through the decorative lamp shade;

[0042] In this embodiment, a lifting frame 9 is provided on the outer side of the support column. A decorative lamp shade 10 is provided on the top surface of the lifting frame. The height of the decorative lamp shade is less than the depth of the concave cavity, so that it can be completely retracted into the concave cavity. A guide rod 11 is provided at the top of the lifting frame, and the end of the guide rod is inserted into the lifting guide groove. The lifting frame is a collar structure and a support plate is provided on the bottom wall. It can be a plastic structure or a metal structure. At the same time, the decorative lamp shade can be made into lamp shades of different shapes according to needs. In this embodiment, it is in the shape of a cat's head. The guide rod is mainly used for support. It is fixed to the lifting frame by screws and is lifted and guided in the lifting guide groove to prevent tilting or deviation. The decorative lamp shade is in the shape of a cat's head, and an eye-shaped LED electronic screen is provided on the decorative lamp shade. The eye-shaped LED electronic screen can display a dynamic picture of the eyes rotating through the control of a driving board, so as to improve the effectiveness of decoration.

[0043] In this embodiment, a support bar 12 is provided on the bottom wall of the lifting frame. A motor slider 13 is provided between the guide rod and the support bar in a translatable manner. The support bar cooperates with the guide rod to ensure the smoothness and effectiveness of lifting, and is also beneficial to the installation and translation operation of the motor slider. The length of the motor slider is less than the distance between the symmetric edges of the top surface of the support and the support columns, ensuring the effectiveness of translation.

[0044] In this embodiment, a motor 14 is fixed to the side of the motor slider, and a driving gear 15 is fixed to the main shaft of the motor. A reset structure 16 and a control structure 17 are provided between the motor and the lifting frame. The reset structure makes the driving gear engage with the tooth groove of the rack column, and the control structure makes the driving gear disengage from the tooth groove of the rack column. The motor is a conventional structure in the prior art and is mainly used for upward driving. The reset structure mainly ensures the meshing effectiveness and reliability of the driving gear of the motor with the rack column, and the control structure disengages the driving gear from the rack column to facilitate rapid descent under the action of gravity.

[0045] In this embodiment, the reset structure is a reset spring. The reset spring is arranged on the side of the motor away from the rack column. Under the action of the reset spring, the driving gear meshes with the tooth groove of the rack column. And the control structure includes an electromagnet 171, an electromagnet fixing bracket 172 with an open bottom surface, a silicon steel sheet 173 arranged in the electromagnet fixing bracket and above the electromagnet, and an L-shaped movable connecting rod 175 rotatably connected to the support bar through a pin shaft 174. In this embodiment, the L-shaped movable connecting rod is made of a metal structure or other hard material structures, which needs to provide sufficient strength to drive the motor slider to translate away from the rack column when rotating around the pin shaft. And the silicon steel sheet and the electromagnet are both conventional structures in the prior art. When the electromagnet is energized, it generates a magnetic suction force, causing the silicon steel sheet to act downward and press against the first rod portion 1751 of the L-shaped movable connecting rod. When the electromagnet is not energized, the silicon steel sheet is in a balanced state under the action of the L-shaped movable connecting rod and is above the electromagnet, having a downward movement space.

[0046] During processing and assembly, the pin shaft is connected to the corner of the L-shaped movable connecting rod, and the upper part of the side surface of the second rod portion 1752 of the L-shaped movable connecting rod abuts against the side surface of the main shaft of the motor near the rack column. A downward abutting convex column 18 is fixed to the edge of the silicon steel sheet. When the electromagnet is energized to generate a suction force, the silicon steel sheet moves downward, and the bottom end of the abutting convex column presses against the top surface of the first rod portion of the L-shaped movable connecting rod, causing the L-shaped movable connecting rod to rotate around the pin shaft. The second rod portion of the L-shaped movable connecting rod drives the motor main shaft and the motor slider away from the rack column. When the L-shaped movable connecting rod rotates, the reset spring will be compressed, deforming and storing energy, which is convenient for quick reset when the electromagnet is not energized.

[0047] In this embodiment, guide rail grooves are provided on the bottom surface of the guide rod and the top surface of the support bar. Slider protrusions 19 that cooperate with the guide rail grooves are provided on both the top surface and the bottom surface of the motor slider. The slider protrusions are slidably arranged in the guide rail grooves. The cross-sectional shape of the guide rail groove is V-shaped, and the shape of the slider protrusion is the same as that of the guide rail groove and can be at both ends of the top surface and the bottom surface.

[0048] In this embodiment, in order to ensure the installation stability of the reset spring, a fixing ring 20 is provided on the outer side of the motor. A connecting protrusion 21 is fixed on the outer wall of the fixing ring. An installation protrusion 22 is fixed on the inner wall of the lifting frame. Both ends of the reset spring are respectively fixed on the connecting protrusion and the installation protrusion. It can ensure the installation stability and reliability of the reset spring, preventing loosening or falling off.

[0049] To ensure the stroke, a travel switch 23 is respectively fixed to the upper and lower sides of the rack column; a travel bump is fixed to the inner wall of the lifting frame, and the travel bump is located between the two travel switches; during use, when the lifting frame is lifted or lowered, the travel bump presses against one of the travel switches to achieve position limitation.

[0050] In this embodiment, a control circuit board with a voice-activated switch is fixed inside the lifting frame, and the control circuit board is connected to the motor, the electromagnet, and the light source structure. The control circuit board is a conventional structure of the prior art and is only simply applied, so it is not described in detail. Moreover, a corresponding power supply battery can be provided, or an external power cord can be used for power supply.

[0051] Its working principle is as follows: When the motor starts, it drives the driving gear to rotate. Through the rack column meshing with the driving gear, the entire lifting frame rises inside the outer box. During the rising process, the decorative lamp cover at the top gradually pushes the outer cover upward and makes the decorative lamp cover protrude upward. During the rising process, position limitation is carried out through the travel switch. The eye-shaped LED electronic screen can display a dynamic picture of the eyes rotating through the driving board. When there is external sound, the voice-activated switch starts the control circuit board to energize the electromagnet. The suction force generated by the electromagnet causes the silicon steel sheet to move downward and press against the first rod portion of the L-shaped movable connecting rod, and makes the L-shaped movable connecting rod rotate around the pin shaft, and translates the motor and the motor slider, and compresses the return spring. At the same time, the driving gear is separated from the rack column. Under the action of gravity, the entire lifting frame naturally falls back, and at the same time the outer cover is also closed, achieving the effect of hiding when encountering sound.

[0052] The utility model has positive effects: The structure of the utility model is reasonably arranged. By setting the rack column in cooperation with the light source structure, the lifting frame, the motor, and the driving gear, the lifting and lowering operation of the lifting frame can be effectively realized through the motor cooperating with the driving gear, so as to change the height of the decorative lamp cover protruding from the top surface of the outer box, thereby achieving the adjustment operation of changing the light irradiation angle and range. And when the decorative lamp cover rises, it will drive the rotation angle adjustment of the outer cover, and automatically fall back when encountering sound and at the same time close the outer cover, thereby achieving the action of covering when simulating shyness and improving the decorative effectiveness;

[0053] Moreover, a reset structure and a control structure are provided between the motor and the lifting frame. In cooperation with the motor slider that can be translated between the guide rod and the support strip, the reset structure can ensure the meshing of the driving gear and the rack column, ensuring the effectiveness and stability of the rising. Through the control structure, the driving gear can be separated from the rack column. At this time, under the action of the self-gravity of the lifting frame and the motor, etc., it descends, improving the convenience and effectiveness of use, and the use is stable, reliable, and has strong applicability.

[0054] The standard parts used in this embodiment can be directly purchased from the market. As for the non-standard structural components described in the specification, they can also be processed without doubt directly according to the existing common technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt the conventional models in the existing technology. Therefore, no specific description will be made here.

[0055] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And these obvious changes or modifications derived from the essence of the present utility model still fall within the protection scope of the present utility model.
