Description

Technical Field

[0001] This invention relates to the field of lighting desk lamp technology, and in particular to an energy-saving desk lamp with an automatically oriented lampshade based on a linkage structure. Background Technology

[0002] A table lamp is a household appliance used for lighting, typically placed on a desk, bedside table, or in the living room, providing a localized lighting solution. Table lamps come in many varieties, including floor lamps, table lamps, and wall lamps, with different styles and functions to meet diverse consumer needs. However, during use, the power cord of a table lamp often leaves a long gap between the external power cord and the wall socket, which can be dangerous and prone to detachment from the wall upon impact, resulting in lower safety.

[0003] As disclosed in CN115199964B, a dimmable smart LED lamp features a winding roller within its base. An external power cord is wound around this roller, and a winding knob is connected to the top of the roller. When the smart LED lamp is plugged in, the winding roller can be rotated via the knob to wind up the power cord, eliminating the need to lay the cord on the floor or bedside table and preventing children from tripping over it. Furthermore, in bedroom wiring, the height of the wall socket near the bed is generally slightly higher than the bedside table. Therefore, the LED lamp can be placed flush against the wall on the bedside table below the socket, ensuring the power cord outlet on the back of the base faces the wall socket, minimizing the distance between the LED lamp and the socket. The base further shields the plug and socket, completely concealing the power cord and further reducing the risk of electric shock from children pulling or playing with it. The back of the LED light base features a locking bracket that engages with the protective cover. This allows the cover to be installed on the wall socket to protect the wiring. The bracket then engages with the cover, and during this process, the power cord can be wound up, making operation easier and less obstructed by the LED light base. The power cord is completely retracted and concealed, while the cover protects the wiring, reducing the risk of electric shock. The cover and bracket work together to further secure the base. Additionally, the base is supported by telescopic legs, allowing it to rest on a bedside table, improving stability and preventing accidental drops and damage.

[0004] It has significant drawbacks: during installation, the connector will abut against the socket, requiring considerable force to press the base close to the wall socket to retract the connector. As pressure is applied, the connector gradually moves closer to the pin hole, resulting in poor efficiency. Furthermore, the connector is inserted directly into the pin hole, so when the base encounters significant tension, the connector will come out of the pin hole, leading to poor fixation. Summary of the Invention

[0005] This application provides an automatic directional energy-saving desk lamp with a linkage structure. It solves the problems of existing technologies where, during installation, the connector abuts against the base, requiring significant force to press the base close to the wall socket to retract it. During this continuous pressing, the connector gradually approaches the pin hole, resulting in poor efficiency. Furthermore, the direct insertion method between the connector and the pin hole leads to the connector detaching under significant tension, resulting in poor fixation. This application achieves a solution by tilting the telescopic rod, the limiting cylinder, and the limiting hole. When the fixing base is under force, the tilted limiting cylinder provides a counter-force to the fixing cover, improving fixation. Moreover, the limiting cylinder's extension and retraction are controlled by an electromagnet, ensuring that it does not abut against the side of the fixing cover furthest from the fixing base during installation, further improving installation efficiency.

[0050] The rotation axis of the limiting cylinder is on the same straight line as the axis of the limiting cylinder;

[0063] As an improvement, the second wire hole is located at the inner apex of the sliding cylinder.

[0064] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0065] Firstly, the telescopic rod, the limiting cylinder, and the limiting hole are tilted. After the fixed base is subjected to force, the tilted limiting cylinder can provide a pulling force in the opposite direction to the fixed cover, thereby improving the fixing effect. Furthermore, the telescopic movement of the limiting cylinder is controlled by an electromagnet. During the installation process, the limiting cylinder does not contact the side of the fixed cover away from the fixed base, which can improve the installation efficiency.

[0066] Secondly, the connection between the limiting cylinder and the limiting hole is improved by the interlocking of the spiral slide and the spiral protrusion. The spiral rotation generates greater friction, increasing the stability of the connection. Compared to a simple direct-insertion pin connection, this method is less prone to accidental removal, enhancing the overall structural stability of the equipment. Furthermore, the mutual fixation of the limiting cylinder and the limiting hole by the spiral slide and the spiral protrusion reduces the impact force of the limiting cylinder inserting into the limiting hole. This helps protect the limiting cylinder and the limiting hole from potential damage caused by sudden impacts between the spiral slide and the spiral protrusion, extending the equipment's service life. It also enhances wear resistance; the spiral structure has a larger contact area than the direct-insertion type, meaning that under the same pressure, the pressure per unit area is reduced, thus reducing wear.

[0067] Thirdly, the expansion of the expansion membrane and its contact with the limiting hole and the inner wall of the spiral protrusion greatly increases the friction between the limiting cylinder and the limiting hole, thereby significantly improving the stability of the fixation. Even when subjected to external force, the connector is more difficult to come out of the pin hole. Furthermore, the expansion membrane sleeved on the outside of the limiting cylinder can reduce the wear of the limiting cylinder and improve the service life of the device. The adjustable fixing force can be precisely adjusted by controlling the inflation of the expansion membrane. This adjustability allows the design to adapt to limiting holes of different sizes and materials, as well as the fixing requirements of different application scenarios.

[0068] Fourth, it can further improve the fixation stability. By using the electromagnet to attract the magnetic material at one end of the limiting cylinder, a tighter contact surface can be formed, increasing the friction between the limiting cylinder and the limiting hole. This increased friction helps to resist external forces, improve the stability of the connection, and prevent the limiting cylinder from loosening during long-term use. Furthermore, the continuous attraction of the limiting cylinder by the electromagnet can continuously improve the fixation effect. Attached Figure Description

[0094] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0095] Example 1: As Figures 1-13 As shown, this application discloses an energy-saving desk lamp with an automatic orientation based on a linkage structure, including a support component 100 and a clamping component 200.

[0096] The support assembly 100 includes a fixing base 110, which is rectangular in shape.

[0097] The clamping assembly 200 includes a fixing cover 210, a sliding plate 220, and a sliding cylinder 230;

[0098] The fixing cover 210 is a cuboid shape that extends through its length. One end of the fixing cover 210 is fixed to one side of the fixing seat 110, and the fixing seat 110 blocks one end of the cavity of the fixing cover 210.

[0099] The through-direction of the fixed cover 210 is parallel to the ground;

[0100] The sliding plate 220 is rectangular. In the initial state, the sliding plate 220 is slidably connected in the cavity of the fixed cover 210, and the four sides of the sliding plate 220 are completely in contact with the inner wall of the cavity of the fixed cover 210.

[0101] The sliding cylinder 230 is a cuboid shape that extends through its length. The sliding cylinder 230 is fixed to the side of the sliding plate 220 away from the fixed base 110. The through direction of the sliding cylinder 230 is parallel to the through direction of the cavity of the fixed cover 210. The sliding cylinder 230 is located at the center of the sliding plate 220.

[0102] The clamping assembly 200 also includes a limiting hole 211;

[0103] The four side walls of the fixing cover 210 are provided with limiting holes 211. The limiting holes 211 penetrate the side walls of the fixing cover 210. The limiting holes 211 are inclined, and the inclination angle of the limiting holes 211 is 15-20 degrees.

[0104] It also includes a limiting component 300, the number of which is the same as the number of limiting holes 211 and they correspond one-to-one. Multiple limiting components 300 are evenly arranged on the outer wall of the sliding cylinder 230.

[0105] The limiting component 300 includes a telescopic rod 310 and a limiting cylinder 320;

[0106] The telescopic rod 310 is fixed to the outer wall of the sliding cylinder 230, and the limiting cylinder 320 is located at the end of the telescopic rod 310 away from the sliding cylinder 230;

[0107] The limiting cylinder 320 is cylindrical, and the axis of the limiting cylinder 320 and the axis of the telescopic rod 310 are on the same straight line.

[0108] Both the telescopic rod 310 and the limiting cylinder 320 are inclined, and the inclination angles of the telescopic rod 310 and the limiting cylinder 320 are consistent with the inclination direction and inclination angle of the corresponding limiting hole 211.

[0109] In its initial state, the limiting cylinder 320 is slidably disposed within the limiting hole 211;

[0110] The telescopic rod 310 is tilted in the direction of extension and retraction towards the side away from the fixed base 110;

[0111] The end of the limiting cylinder 320 away from the telescopic rod 310 is made of magnetic material;

[0112] The support assembly 100 includes an adjustment port 111, an adjustment rod 120, a lighting lamp 130, an adjustment foot 140, a winder 150, a power cord 160, and a control panel 170.

[0113] The adjusting rod 120 is fixed on the fixed base 110. The adjusting rod 120 is a connecting rod structure. The lighting lamp 130 is fixed at one end of the adjusting rod 120. The lighting direction and angle of the lighting lamp 130 can be adjusted by manually adjusting the adjusting rod 120.

[0114] The lower side of the fixed base 110 has an adjustment port 111. There are multiple adjustment ports 111, which are evenly spaced. The adjustment port 111 has a thread inside. The adjustment foot 140 has a thread on the outside. The number of adjustment feet 140 is the same as the number of adjustment ports 111, and they correspond one-to-one. The adjustment foot 140 is threaded into the adjustment port 111.

[0115] The height of the fixed base 110 can be adjusted by rotating the adjusting foot 140;

[0116] The fixing base 110 has a winder 150 on the side near the fixing cover 210. The winder 150 is an automatic winder and is existing technology, so it will not be described in detail here.

[0117] The winder 150 is used to wind up the power cord 160. The end of the power cord 160 away from the plug passes through the fixing base 110 and is wound on the winder 150. The fixing base 110 is equipped with a control panel 170.

[0118] The end of the power cord 160 away from the plug is electrically connected to the control panel 170, and the lighting lamp 130 is electrically connected to the control panel 170.

[0119] The clamping assembly 200 also includes a wire hole 221, a clamping group and an electromagnet 260;

[0120] The sliding plate 220 has a wire hole 221, which passes through the sliding plate 220 and the power cable 160 passes through the wire hole 221.

[0121] The wire passage hole 221 is located inside the sliding cylinder 230;

[0122] There are four clamping assemblies, which correspond to the four sides of the cavity of the sliding cylinder 230 respectively. Each clamping assembly includes a telescopic rod 240 and a clamping plate 250.

[0123] One end of the telescopic rod 240 is fixed to the inner wall of the cavity of the sliding cylinder 230, and the end of the telescopic rod 240 away from the sliding cylinder 230 is fixed to the clamping plate 250.

[0124] The clamp 250 is used to clamp the four sides of the wall socket;

[0125] The electromagnet 260 is fixed on the side of the sliding plate 220 away from the fixed base 110, and the electromagnet 260 is located in the middle of the sliding plate 220.

[0126] When the electromagnet 260 is energized, it can attract the magnetic material at one end of the limiting cylinder 320, thereby causing the telescopic rod 310 to retract.

[0127] The electromagnet 260 is electrically connected to the control panel 170; the power source of the electromagnet 260 is the power obtained by the power cord 160 being plugged into the wall socket.

[0128] The control panel 170 is used to control the opening and closing of both the lighting lamp 130 and the electromagnet 260;

[0129] When not subjected to external force, both the first telescopic rod 240 and the second telescopic rod 310 are in the extended state.

[0130] During use, the user adjusts the height by rotating the foot 140 to adapt to the height of the wall socket. First, the power cord 160 is pulled out and plugged into the wall socket. The device is then connected to the power supply. The electromagnet 260 is energized via the control panel 170. The electromagnet 260 attracts the magnetic material at one end of the limiting cylinder 320, causing the telescopic rod 310 to retract and the limiting cylinder 320 to disengage from the limiting hole 211. The sliding plate 220 and the sliding cylinder 230 are then removed from the fixing cover 210. The sliding plate 220 and the sliding cylinder 230 are brought close to the wall socket and positioned on the four sides of the wall socket by the clamping plates 250, fixing the position of the sliding plate 220 and the sliding cylinder 230. Then, the position of the fixing base 110 is moved so that the sliding plate 220 and the sliding cylinder 230 are positioned closer to the wall socket. The 0 can be inserted into the fixed cover 210. After the limiting cylinder 320 enters the fixed cover 210, the electromagnet 260 is de-energized. As the sliding plate 220 and the sliding cylinder 230 continue to extend, the limiting cylinder 320 can be inserted into the limiting hole 211 for limiting. The lighting lamp 130 is controlled by the control panel 170, and the lighting mode of the lighting lamp 130 can be adjusted through the control panel 170. At the same time, the illumination angle can be adjusted through the adjusting rod 120. When it is necessary to disassemble the device, the electromagnet 260 is activated, attracting the magnetic material at one end of the limiting cylinder 320, causing the limiting cylinder 320 to disengage from the limiting hole 211. Then, the fixed base 110 is moved, the sliding plate 220 and the sliding cylinder 230 are disassembled, and the clamp 250 is removed from the wall socket.

[0131] Compared with the existing technology, by tilting the telescopic rod 310, the limiting cylinder 320 and the limiting hole 211, after the fixing base 110 is subjected to force, the tilted limiting cylinder 320 can provide a reverse pulling force on the fixing cover 210, thereby improving the fixing effect. In addition, the telescopic extension and retraction of the limiting cylinder 320 is controlled by the electromagnet 260. During the installation process, the limiting cylinder 320 does not abut against the side of the fixing cover 210 away from the fixing base 110, thereby improving the installation efficiency.

[0132] Example 2: In Example 1, the inclined telescopic rod 310, the limiting cylinder 320, and the limiting hole 211 improve the fixing effect. However, the fixing effect is poor in use. When the fixing seat 110 encounters a large force, it may still detach from the limiting hole 211. At the same time, when the limiting cylinder 320 enters the limiting hole 211, the telescopic rod 310 has a large impact force, which can cause damage to the limiting cylinder 320 and the limiting hole 211, reducing its service life. Therefore, the solution of Example 1 is improved, such as... Figures 14-15 As shown:

[0133] The clamping assembly 200 also includes a spiral protrusion 212;

[0134] The limiting hole 211 has a spiral protrusion 212 inside. In the initial state, the axis of the spiral line of the spiral protrusion 212 is on the same straight line as the axis of the limiting cylinder 320.

[0135] The limiting cylinder 320 is rotatably connected to the telescopic rod 310, and the rotation axis of the limiting cylinder 320 is on the same straight line as the axis of the limiting cylinder 320.

[0136] The limiting component 300 also includes a spiral slide 321;

[0137] The outer wall of the limiting cylinder 320 has a spiral slide 321 that cooperates with the spiral protrusion 212, and the axis of the spiral slide 321 is on the same straight line as the axis of the limiting cylinder 320.

[0138] When the limiting cylinder 320 enters the limiting hole 211, the spiral protrusion 212 and the spiral slide 321 cooperate, and the limiting cylinder 320 rotates continuously as it extends into the limiting hole 211.

[0139] When the limiting cylinder 320 extends into the limiting hole 211, the limiting cylinder 320 rotates at one end of the telescopic rod 310. The limiting cylinder 320 rotates into the limiting hole 211, and the spiral slide 321 and the spiral protrusion 212 cooperate with each other to fix the position of the limiting cylinder 320.

[0140] The limiting cylinder 320 and the limiting hole 211 are fixed together by the cooperation of the spiral slide 321 and the spiral protrusion 212, which improves the connection effect between them. The spiral rotation generates greater friction, thereby increasing the stability of the connection. Compared with the simple direct-insertion pin connection, this connection method is more difficult to be accidentally pulled out, improving the overall structural stability of the equipment. Furthermore, when the limiting cylinder 320 and the limiting hole 211 are fixed together by the spiral slide 321 and the spiral protrusion 212, the impact force of the limiting cylinder 320 being inserted into the limiting hole 211 can be reduced. This helps protect the limiting cylinder 320 and the limiting hole 211 from damage that may be caused by sudden impact between the spiral slide 321 and the spiral protrusion 212, extending the service life of the equipment. It also enhances wear resistance. The contact area of ​​the spiral structure is larger than that of the direct-insertion type, which means that under the same pressure, the pressure per unit area is reduced, thereby reducing wear.

[0141] Example 3: In Example 2, the helical slide 321 and helical protrusion 212 improve the fixing effect between the limiting cylinder 320 and the limiting hole 211, and enhance wear resistance. However, during use, while the fixing effect can be improved, after prolonged use, the wear between the limiting cylinder 320 and the limiting hole 211, and between the helical slide 321 and the helical protrusion 212, is significant. The limiting cylinder 320 will wobble within the limiting hole 211, resulting in poor stability. Therefore, the solution in Example 2 is improved, such as... Figures 16-17 As shown:

[0142] The limiting component 300 also includes an expansion membrane 330 and an inflatable plate 340;

[0143] The expansion membrane 330 wraps around the outer wall of the limiting cylinder 320, and the inflation plate 340 is fixed on the expansion membrane 330, with the inflation plate 340 located at the end of the telescopic rod 310 away from the sliding cylinder 230.

[0144] The expansion membrane 330 and the limiting cylinder 320 form a sealed expansion space;

[0145] The inflatable plate 340 is equipped with an air inlet pipe, which is connected to the expansion space, and the air inlet pipe is equipped with a valve.

[0146] The air inlet pipe input end on the inflatable plate 340 can be connected to an external air inlet structure.

[0147] The air inlet pipe on the inflatable plate 340 is connected to the air inlet structure. When the valve is opened, the expansion space can be expanded or contracted.

[0148] Before the limiting cylinder 320 extends into the limiting hole 211, the expansion membrane 330 is completely attached to the limiting cylinder 320 and the spiral slide 321. After the limiting cylinder 320 extends into the limiting hole 211, the air intake structure is connected through the air intake pipe on the inflation plate 340, and the valve on the air intake pipe is opened to inflate the expansion space, causing the expansion membrane 330 to expand. After expansion, the expansion membrane 330 can completely adhere to the inner wall of the limiting hole 211 and the spiral protrusion 212 for fixation. The expansion membrane 330 located outside the limiting hole 211 can adhere to the outer side of the fixing cover 210 after inflation. Before disassembly, the air intake pipe on the inflation plate 340 is connected to the air intake structure, and the valve on the air intake pipe is opened to evacuate the expansion space, causing the expansion membrane 330 to completely adhere to the limiting cylinder 320 and the spiral slide 321. After that, disassembly can be performed normally.

[0149] The expansion of the expansion membrane 330, along with its contact with the inner wall of the limiting hole 211 and the spiral protrusion 212, greatly increases the friction between the limiting cylinder 320 and the limiting hole 211, thus significantly improving the stability of the fixation. Even under external force, the connector is less likely to come out of the pin hole. Furthermore, the expansion membrane 330 sleeved on the outside of the limiting cylinder 320 reduces wear on the limiting cylinder 320 and extends the service life of the device. The adjustable fixing force, by controlling the inflation amount of the expansion membrane 330, allows for precise adjustment of the fixing force between the limiting cylinder 320 and the limiting hole 211. This adjustability enables the design to adapt to limiting holes 211 of different sizes and materials, as well as the fixing requirements of different application scenarios.

[0150] Example 4: In Example 3, the expansion of the expansion membrane 330 improves the fixing effect of the limiting cylinder 320 within the limiting hole 211. However, during the use of the device, further improvements can be made to enhance the fixing effect of the limiting cylinder 320 within the limiting hole 211. Based on this, improvements are made to the scheme of Example 3, such as... Figure 3 , Figures 18-20 As shown:

[0151] The support assembly 100 includes a second winder 180. The fixed base 110 has a second winder 180 on the side near the fixed cover 210. The second winder 180 is located above the first winder 150, and the second winder 180 has the same structure as the first winder 150.

[0152] The clamping assembly 200 also includes a wire hole 222, an electromagnet 270, and a connecting wire 280;

[0153] The sliding plate 220 has a wire passage hole 222, which is located inside the sliding cylinder 230 and at the top corner of the sliding cylinder 230.

[0154] The second electromagnet 270 has the same shape as the sliding cylinder 230, and the second electromagnet 270 is fixed at the end of the sliding cylinder 230 away from the sliding plate 220.

[0155] The second winder 180 is used to wind up the connecting line 280. The connecting line 280 is wound inside the second winder 180. One end of the connecting line 280 is electrically connected to the control panel 170. The end of the connecting line 280 away from the control panel 170 passes through the fixing base 110 and the wire hole 222 and is connected to the electromagnet 270.

[0156] The limiting cylinder 320 is elastic;

[0157] When the electromagnet 270 is energized, it can attract the magnetic material at one end of the limiting cylinder 320, causing the elastic limiting cylinder 320 to bend.

[0158] During use, after the limiting cylinder 320 is inserted into the limiting hole 211 and the expansion film 330 is fully expanded, the electromagnet 270 is activated, attracting the magnetic material at one end of the limiting cylinder 320, causing the limiting cylinder 320 to bend towards the wall socket, thus providing a fixing effect.

[0159] This further improves the stability of the connection. By using the electromagnet 270 to attract the magnetic material at one end of the limiting cylinder 320, a tighter contact surface can be formed, increasing the friction between the limiting cylinder 320 and the limiting hole 211. This increased friction helps resist external forces, improves the stability of the connection, and prevents the limiting cylinder 320 from loosening during long-term use. Furthermore, the continuous attraction of the limiting cylinder 320 by the electromagnet 270 continuously improves the fixing effect.
