The term "a" should not be construed as a limitation on the quantity.

[0026] To address the shortcomings of existing technologies, this utility model provides a lifting mechanism for a multifunctional ambient light, which facilitates the adjustment of the height of the ambient light's display screen and the illumination height of the light strip plate, thereby providing people with significant functional cues.

[0027] like Figure 1 and Figure 2 As shown, the lifting mechanism of the multifunctional ambient light of this utility model includes a stator bracket 2 located inside the lampshade housing 1 and a movable bracket 3 sleeved on the outside of the lampshade housing 1. The lampshade housing 1 and the movable bracket 3 are made of transparent material to facilitate light transmission. Furthermore, a vertical opening is provided on one side of the lampshade housing 1 to facilitate the engagement of the movable bracket 3 with the stator bracket 2 located inside the lampshade housing 1.

[0028] The lampshade housing 1 also contains a motherboard 11. The motherboard 11 can be an existing main control chip (microprocessor unit MCU), and the lower end of the lampshade housing 1 can be provided with a lower shell 13 to enclose the motherboard 11 within the lampshade housing 1 and the lower shell 13.

[0029] The lifting mechanism of this multifunctional ambient light utilizes the working principle of a U-shaped linear motor to achieve automatic sliding of the moving bracket 3 relative to the stator bracket 2. Specifically, the stator bracket 2 is evenly, paired, and crosswise provided with multiple pairs of vertically arranged N-pole magnets 4 and S-pole magnets 5. The moving bracket 3 contains multiple moving coils 6, for example, three moving coils 6. These multiple moving coils 6 are located between the multiple pairs of N-pole magnets 4 and S-pole magnets 5, and the moving bracket 3 is provided with a moving plate 7. All of the multiple moving coils 6 are electrically connected to the moving plate 7. The moving plate 7 is electrically connected to the main board 11. Thus, the main board 11 can electrically control the multiple moving coils 6, and through this electrical control, the automatic sliding of the moving bracket 3 relative to the stator bracket 2 is achieved.

[0030] Meanwhile, in this invention, a displacement sensor is provided between the stator support 2 and the moving support 3. Through this displacement sensor, the displacement of the moving support 3 as it moves up and down along the stator support 2 can be measured, that is, the height of the moving support 3 can be measured.

[0031] The displacement sensor can be a capacitive grating sensor, a magnetic grating sensor, or an optical grating sensor. Preferably, the displacement sensor is a capacitive grating sensor.

[0032] The moving plate 7 is equipped with a reading head 8, and the moving plate 7 is electrically connected to the reading head 8. The stator support 1 is also equipped with an adapter plate 10. The displacement sensor is a capacitive grating sensor, which includes a moving grating on the reading head 8 and a stationary grating on the adapter plate 10. The stationary grating is connected to the main board 11 via a signal line. Therefore, the main board 11 can determine the position of the moving support 3 relative to the stator support 2, i.e., the height of the moving support 3, by the relative position of the moving grating and the stationary grating. Simultaneously, similar to the principle of an electronic vernier caliper, the reading head 8 can also display the height of the moving support 3 in real time, facilitating manual adjustment of the moving support 3's height.

[0033] The capacitive grating sensor used in this invention has many outstanding advantages over other types of sensors:

[0034] 1. Large measuring range and high resolution. When measuring online displacement, the measuring range can reach 20m with a resolution of 2mm, and the measuring speed is also relatively high, with a linear measuring speed of 1.5m / s.

[0035] 2. Capacitive grating measurement is a non-contact measurement, so capacitive grating sensors have the advantages of non-contact sensors, such as minimizing frictional resistance during measurement and preventing a decrease in measurement accuracy due to surface wear of the measuring components.

[0036] 3. Simple structure. The sensing element of the capacitive grating sensor mainly consists of a moving grating and a stationary grating. The signal lines can all be led out from the stationary grating, and the moving grating, as a moving part, can be without leads, which greatly simplifies the design of the sensor.

[0037] 4. Capacitive grating sensors are a type of digital sensor that facilitates long-distance signal transmission, has virtually no data transmission error, and can update data at a rate of up to 50 times per second.

[0038] 5. Extremely low power consumption. The normal operating current is less than 10mA, and the sensor's sensitive element can work for a long time. A single button battery can power it continuously for more than a year. Utilizing this feature, a quasi-absolute displacement sensor can be designed.

[0039] 6. It has a significant price advantage, with a performance-price ratio far exceeding that of similar sensors.

[0040] Furthermore, in this invention, preferably, the moving part bracket 3 is provided with a positioning mechanism that allows it to be suspended at any position on the stator bracket 2. For example, the moving part bracket 3 is provided with a spring 9 that constantly presses against the adapter plate 10. Thus, when the plurality of moving part coils 6 are not energized, that is, when the moving part bracket 3 is not moving, the elastic force of the spring 9 ensures that the moving part bracket 3 can be suspended at any position on the stator bracket 1.

[0041] Therefore, the multifunctional lifting mechanism of this utility model enables the moving bracket 3 to slide and position precisely up and down on the stator bracket 2, either manually or automatically.

[0042] Furthermore, in this utility model, preferably, the movable bracket 3 is also provided with a display screen 12 connected to the main board 11, and the movable bracket 2 is also provided with a light strip plate 16 connected to the main board 11. The light strip plate 16 is provided with multiple LED beads, and each LED bead can be lit individually. Additionally, the top of the lampshade housing 1 is provided with a mode switching knob 14 and an encoder plate 15 connected to the mode switching knob 14. The encoder plate 15 is connected to the main board 11, thereby enabling the main board 11 to select the functional mode of the ambient light based on the mode switching knob 14, and to adjust the height of the movable bracket 3 based on the set data of the selected functional mode.

[0043] For example, by rotating the mode switching knob 1 and clicking to confirm, the brightness adjustment mode is selected. At this time, the user can manually adjust the height of the moving bracket 3, and the mainboard 11 can determine the brightness level of the ambient light based on the height of the moving bracket 3. Alternatively, the user can manually set the brightness level of the ambient light via a mobile app and send it to the mainboard 11 via wireless network, allowing the mainboard 11 to determine the height of the moving bracket 3 based on the brightness level of the ambient light and adjust the height of the moving bracket 3 through the lifting mechanism. For example, as... Figure 3 As shown, brightness adjustment from 0 to 100 levels can be achieved. When the moving bracket 3 moves to the top of the stator bracket 2, the brightness level is 100; when it moves to the bottom of the stator bracket 2, the brightness level is 0; and when it moves to the middle position of the stator bracket 2, the brightness level is 50.

[0044] Furthermore, during the adjustment of the ambient light's brightness level, the display screen 12 can display the ambient light's brightness level in real time, for example, Figure 3 In this context, the display screen 12 shows an ambient light with a brightness level of 55. Furthermore, the LEDs on the light strip plate 16 located below the horizontal level of the moving bracket 3 are illuminated according to the ambient light's brightness level (i.e., Figure 3 (The yellow color in the text indicates that the light is on). Therefore, the display screen 12 and the light strip panel 16 can provide people with prominent functional cues.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit the scope of protection of this utility model. Those skilled in the art can modify or make equivalent substitutions to the technical solution of this utility model based on the concept of this utility model, without departing from the essence and scope of the technical solution of this utility model.
