In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0026] refer to Figure 1 and Figure 2 , the cabinet 100 according to the embodiment of the present invention includes a cabinet body 101, a drawer 102, a sensing module 103, a light emitting module 104 and a controller 105. The drawer 102 is slidably installed in the cabinet body 101, and the sensing module 103 is used to detect the extension distance of the drawer 102 relative to the cabinet body 101. The light emitting module 104 is installed in the drawer 102, and the light emitting module 104 and the sensing module 103 are both connected to the drawer 102. The controller 105 is configured to: change at least one of the color and brightness of the light emitted by the light emitting module 104 according to the extension distance. In this way, when the user pulls out the drawer 102, the extension distance of the drawer 102 relative to the cabinet body 101 changes and is detected by the sensing module 103. The controller 105 controls the light emitting module 104 to emit light of different colors and brightness according to the change in the extension distance, so as to achieve a variety of lighting effects, thereby improving the lighting effect of the drawer.

[0027] It should be noted that, in the present application, the extension distance of the drawer 102 relative to the cabinet 101 refers to the length of the portion of the drawer 102 extending from the opening 117 to the outside of the cabinet 101 in the sliding direction of the drawer 102. Figure 2 In the state shown, the extension distance is minimum.

[0028] It should be noted that the reference Figure 5 In some embodiments of the present invention, the light module 104 uses an LED (light emitting diode) light strip, which includes a plurality of LED lamp beads arranged in a straight line. The LED lamp beads have low operating voltage, low energy consumption and long service life, and the LED lamp beads can emit light of various colors, meeting the lighting requirements of the cabinet 100 of the embodiment of the present invention. In some embodiments of the present invention, the light strip is arranged along the sliding direction of the drawer 102. That is, the length direction of the light module 104 is the same as the sliding direction of 102, and both directions are front-to-back directions.

[0029] In some embodiments of the present invention, the controller 105 is configured to increase the brightness of the light emitted by the light module 104 as the extension distance of the drawer 102 relative to the cabinet 101 increases. The light emitted by the light module 104 can illuminate the drawer 102 so that the user can take and put items. In actual use, if the user needs to put or take out items in the drawer 102, the drawer 102 needs to be pulled out a large distance first. If the extension distance of the drawer 102 is short, then the extension distance of the drawer 102 may not be enough for the user to take and put items, and there is no need to provide more light at this time. Therefore, when the extension distance is small, the brightness of the light emitted by the light module 104 is also small, which is conducive to reducing the energy consumption of the drawer. The increase in the extension distance means that the requirements for the brightness in the drawer 102 will also increase, so the brightness of the light module 104 increases with the increase in the extension distance of the drawer 102, which can also enhance the user's experience.

[0030] In some embodiments of the present invention, the light module 104 has a marquee lighting mode, and the controller 105 is configured to: when the distance that the drawer 102 extends relative to the cabinet 101 is greater than a first preset distance, the light module 104 switches to the marquee lighting mode. The design of the first preset distance determines that the user needs to use the area in the drawer 102 to a greater extent. When the extension distance is greater than the first preset distance, the light module 104 is switched to the marquee lighting mode to enhance the lighting effect and meet the needs of diversified lighting modes.

[0031] In some embodiments of the present invention, the light module 104 has a monochromatic light mode, and the controller 105 is configured as follows: when the distance that the drawer 102 extends relative to the cabinet 101 is less than the second preset distance, the light module 104 does not emit light, and when the distance that the drawer 102 extends relative to the cabinet 101 is greater than the second preset distance and less than the first preset distance, the light module 104 switches to the monochromatic light mode. If the extension distance of the drawer 102 is too short, then the extension distance of the drawer 102 may not be enough for the user to take and put items, and no light is needed at this time. Therefore, when the extension distance is less than the second preset distance, the light module 104 does not emit light, which is conducive to reducing the energy consumption of the drawer. When the distance that the drawer 102 extends relative to the cabinet 101 is greater than the second preset distance and less than the first preset distance, the light module 104 switches to the monochromatic light mode to meet basic usage requirements, and when the distance that the drawer 102 extends relative to the cabinet 101 is greater than the first preset distance, the exposed area of ​​the light module 104 is larger, and switching the light mode to the marquee light mode can better show the effect of the marquee.

[0032] It should be noted that, in some embodiments of the present invention, the marquee lighting mode refers to a dynamic lighting effect, in which the light turns on and off in a specific form (reciprocating or wave-like, etc.) and shows different colors, while the monochrome lighting mode shows light of fixed color and brightness.

[0033] It should be noted that, in some embodiments of the present invention, the maximum extension distance of the drawer 102 is L, the first preset distance can be L, 0.5L or other values, and the second preset distance is smaller than the first preset distance, specifically, can be 0.2L, 0.1L or other values.

[0034] In some embodiments of the present invention, the controller 105 is configured to: determine the preset distance interval to which the extension distance belongs according to the extension distance of the drawer 102; and adjust the color of the light emitting module 104 to a preset color corresponding to the preset distance interval according to the preset distance interval. In this way, the drawer 102 can pass through different preset distance intervals during the extension process, so that the controller 105 adjusts the color of the light emitting module 104 to the corresponding color to make the lighting effect richer. In some embodiments of the present invention, the colors of the light emitting modules 104 corresponding to different preset distance intervals can be set to the same color to meet the needs of a simple style, or they can be set to different colors to meet the colorful lighting effects. Furthermore, the colors of the light emitting modules 104 corresponding to continuous preset distance intervals can also be set to continuously gradient colors to further enhance the lighting effect. For example, in some embodiments of the present invention, the maximum extension distance of the drawer 102 is L, and there are three preset distance intervals, namely 0~1 / 3L, 1 / 3L~2 / 3L and 2 / 3L~L. When the extension distance of the drawer 102 is less than 1 / 3L, the light emitting module 104 emits yellow light, when the extension distance of the drawer 102 is between 1 / 3L and 2 / 3L, the light emitting module 104 emits blue light, and when the extension distance of the drawer 102 is greater than 2 / 3L, the light emitting module 104 emits white light. The above is only an example, and different numbers and ranges of preset distance intervals can be adjusted according to usage requirements. The light emitting module 104 can also be set to emit different light colors in each interval.

[0035] refer to Figure 1 and Figure 3In some embodiments of the present invention, the sensing module 103 includes a first sensing portion 106 and a plurality of second sensing portions 107, one of the first sensing portion 106 and the second sensing portion 107 is installed on the drawer 102, and the other is installed on the cabinet 101, and the plurality of second sensing portions 107 are arranged at intervals along the sliding direction of the drawer 102, and when the first sensing portion 106 is located within the detection range of the second sensing portion 107, a second sensing portion 107 corresponding to the first sensing portion 106 is triggered. Such a design enables the sliding of the drawer 102 to change the relative distance between the first sensing portion 106 and the plurality of second sensing portions 107, so that the first sensing portion 106 triggers different second sensing portions 107 during the sliding process of the drawer 102, so that the current extension distance can be intuitively determined by determining which part of the second sensor is triggered at this time, thereby simplifying the judgment logic and improving the accuracy of the judgment.

[0036] It should be noted that, in some embodiments of the present invention, the sensing module 103 can also use other types of displacement sensors, such as a pull-rope displacement sensor, a photoelectric sensor, etc. When a pull-rope displacement sensor is used, one end of the pull rope is fixed to the cabinet 101, and the other end is connected to the drawer 102. When the drawer 102 is extended, the drawer 102 drives the other end of the pull rope to move to pull it out, so that the sensor detects the extension distance of the drawer 102; the photoelectric sensor is a transmitter installed on one of the drawer 102 or the cabinet 101, and a receiver installed on the other. The transmitter and the receiver are arranged opposite to each other. When the drawer 102 is extended, the distance between the transmitter and the receiver changes, thereby changing the path and time of the reflected light, etc., so as to know the value of the extension distance.

[0037] In some embodiments of the present invention, the first sensing part 106 is a magnet, and the second sensing part 107 is a reed switch. When the distance between the magnet and the reed switch is less than a certain value (such as 2 mm), the two ends of the reed switch will be connected, and when the distance between the magnet and the reed switch is greater than the set value, the reed switch will be disconnected. Therefore, when the drawer 102 slides, the magnet senses different reed switches to know the current extension distance. The first sensing part 106 and the second sensing part 107 are respectively set as a magnet and a reed switch because the structures of the two are relatively simple and low in cost. The installation method only needs to fix the two on the drawer 102 and the cabinet 101, which meets the multiple requirements of low cost, convenient maintenance and installation. It should be noted that in some embodiments of the present invention, when the first sensing part 106 is a magnet, the second sensing part 107 can also use a Hall sensor, which uses the Hall effect to sense the change of the magnetic field, and the current extension distance can also be known. In some embodiments of the present invention, the first sensing portion 106 and the second sensing portion 107 can also be configured as contact sensing, the second sensing portion 107 is configured as a contact switch (such as a micro switch), and the first sensing portion 106 is configured as a bump or other structure. When the drawer slides, the first sensing portion 106 slides over the second sensing portion 107 to press and trigger its contact. Sliding over different second sensing portions 107 can trigger contact switches at different positions, thereby obtaining the current extension distance.

[0038] It should be noted that the reference Figure 1 , Figure 3 as well as Figures 6 to 8 In some embodiments of the present invention, the first sensing unit 106 is fixedly installed in the cabinet 101 through the bracket 801 ( Figure 3 The cabinet 101 is not shown in the figure), and the second sensing part 107 is fixedly mounted on the bottom plate 112 of the drawer 102. Such a design does not hinder the pulling out of the drawer 102, and at the same time fully utilizes the gap between the bottom plate 112 of the drawer 102 and the bottom wall 118 of the cabinet 101, making the overall structure more compact. In some embodiments of the present invention, the first sensing part 106 can also be installed on the drawer 102, and the second sensing part 107 can be installed on the cabinet 101, so that the two are spaced apart and the first sensing part 106 can trigger different second sensing parts 107 as the drawer 102 slides.

[0039] refer to Figure 1In some embodiments of the present invention, the cabinet 100 further includes a wireless power supply module 108, and the wireless power supply module 108 includes a transmitting coil 109 and a receiving coil 110, the transmitting coil 109 is installed in the cabinet 101, the receiving coil 110 is installed in the drawer 102, the receiving coil 110 is electrically connected to the light-emitting module 104, the transmitting coil 109 and the receiving coil 110 are magnetically coupled, and the transmitting coil 109 can supply power to the receiving coil 110, so that the receiving coil 110 supplies power to the light-emitting module 104. In the prior art, a power supply method is often used in which a power supply at the cabinet and a light-emitting module at the drawer 102 are directly connected by wires, but the wires may hinder the movement of the drawer 102, and if the wires are long, the wires may be wound, and may even be broken. The use of wireless power supply can avoid the influence of wires on the movement of the drawer 102. It should be noted that, in some embodiments of the present invention, the transmitting coil 109 is connected to an external power supply so that the transmitting coil 109 can be continuously energized. The wireless power supply module 108 of the embodiment of the present invention is mainly used to optimize the wires between the drawer 102 and the cabinet 101 to avoid interfering with the movement of the drawer 102.

[0040] refer to Figure 3 In some embodiments of the present invention, the cabinet 100 also includes a wireless power supply module 108, and the wireless power supply module 108 includes a transmitting coil 109 and a receiving coil 110. The transmitting coil 109 is installed in the cabinet 101, and the receiving coil 110 is installed in the drawer 102. The receiving coil 110 is electrically connected to the light-emitting module 104, and the transmitting coil 109 is magnetically coupled with the receiving coil 110. The transmitting coil 109 can power the receiving coil 110 so that the receiving coil 110 powers the light-emitting module 104. The drawer 102 includes a bottom plate 112, the bottom plate 112 includes a first mounting surface 301 and a second mounting surface 302, the cabinet 101 has a cavity 116 for accommodating the drawer 102, the bottom wall 118 of the cavity 116 is arranged at intervals below the bottom plate 112, and the bottom wall 118 and the bottom plate 112 are arranged opposite to each other, the transmitting coil 109 and the second sensing part 107 are both installed on the bottom wall 118, the receiving coil 110 is installed on the first mounting surface 301, the first sensing part 106 is installed on the second mounting surface 302, and the distance between the first mounting surface 301 and the bottom wall 118 is smaller than the distance between the second mounting surface 302 and the bottom wall 118. Since in some embodiments of the present invention, the first sensing unit 106 and the second sensing unit 107 are induced by magnetic field, and the transmitting coil 109 and the receiving coil 110 are also induced by magnetic field, in order to avoid the interference of the wireless power supply module 108 on the sensing module 103, the bottom plate 112 of the drawer 102 is designed to be stepped, which can reduce the interference degree of the magnetic field of the wireless power supply module 108 on the sensing module 103. It should be noted that, referring to Figure 3 and Figure 7In some embodiments of the present invention, the first mounting surface 301, the second mounting surface 302 and the bottom wall 118 can be set to be flat surfaces to facilitate processing and installation of other components.

[0041] refer to Figure 1 and Figure 3 In some embodiments of the present invention, a plurality of receiving coils 110 are provided, and the plurality of receiving coils 110 are spaced apart along the sliding direction of the drawer 102, and at least one receiving coil 110 is magnetically coupled with the transmitting coil 109. The plurality of receiving coils 110 can ensure that during the extension of the drawer 102, at least one receiving coil 110 can always be magnetically coupled with the transmitting coil 109, so that the transmitting coil 109 supplies power to the receiving coil 110, and power failure can be avoided because the distance between the transmitting coil 109 and the receiving coil 110 exceeds the maximum sensing distance.

[0042] refer to Figure 1 , Figure 3 and Figure 4 In some embodiments of the present invention, the cabinet 100 further includes a light guide plate 111, and the drawer 102 includes a bottom plate 112, an end plate 113, and a side plate 114. Two end plates 113 are provided, and the two end plates 113 are spaced apart along the sliding direction of the drawer 102, and the bottom of the end plates 113 is connected to the bottom plate 112. Two side plates 114 are provided, and the two side plates 114 are spaced apart, and the arrangement direction of the two side plates 114 is perpendicular to the sliding direction. The bottom end of the side plate 114 is connected to the bottom plate 112, and the light guide plate 111 is connected to the side plates 114. The light emitting module 104 is located at the bottom of the light guide plate 111 and faces the light guide plate 111. The light guide plate 111 can make the light softer and enhance the visual effect, while arranging the light emitting module 104 at the bottom of the light guide plate 111 and facing the light guide plate 111 can maximize the light entering the light guide plate 111 and refracting it, further enhancing the lighting effect. Reference Figure 1 In some embodiments of the present invention, when the sliding direction of the drawer 102 is the front-to-back direction as shown in the figure, the arrangement direction of the side panels 114 is the left-to-right direction.

[0043] It should be noted that in some embodiments of the present invention, the light guide plate 111 is made of transparent glass, which can retain the original light of the light emitting module 104 to a large extent and make the light evenly dispersed.

Placing the light emitting module 104 in the mounting groove 502 can improve the overall aesthetics and space utilization, and the limiting plates 501 can well limit the light guide plate 111 to both sides of the drawer 102, thereby improving the structural stability.

When the extension distance of the drawer 102 relative to the cabinet 101 is at the minimum value, the drawer 102 triggers the travel switch 115. The controller 105 is configured to: when the travel switch 115 is triggered by the drawer 102, turn off the light module 104, and when the travel switch 115 is not triggered by the drawer 102, turn on the light module 104. For example, if the light-emitting module 104 is turned off when the drawer 102 is not needed, unnecessary energy loss can be avoided. Specifically, in some embodiments of the present invention, when the travel switch 115 is a contact switch, a spring is provided in the travel switch 115. When the extension distance of the drawer 102 is at the minimum value, the spring is compressed, the travel switch 115 is triggered, and the light-emitting module 104 is turned off; when the drawer 102 is extended, the spring is in a non-compressed state, the travel switch 115 is not triggered, and the light-emitting module 104 is turned on. In some embodiments of the present invention, when the drawer 102 is extended and just disengaged from the travel switch 115, the extension distance is a second preset distance, and the light-emitting module 104 switches from no light to a monochrome light-emitting mode.

[0046] It should be noted that the travel switch 115 can also be set as a non-contact switch, specifically an electromagnetic switch, a photoelectric switch, etc. When the extension distance of the drawer 102 is at the minimum value, the travel switch 115 is triggered and the light-emitting module 104 is turned off. When the travel switch 115 is not triggered, the light-emitting module 104 is turned on.

[0047] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
