Description

Technical Field

[0001] The present invention relates to the technical field of LED desk lamps, and in particular to a flexibly adjustable LED desk lamp. Background Art

[0002] Lighting plays a crucial role in modern life and work, especially in scenarios requiring prolonged concentration, such as reading, writing, drawing, programming, and office work. Compared to traditional desk lamps, LED desk lamps offer higher energy efficiency and longer lifespans, meaning they consume less energy while providing more stable and long-lasting lighting. This is undoubtedly a huge advantage for those who spend long periods of time working or studying at a desk.

[0003] Chinese patent publication number CN114941814B discloses an easily adjustable LED desk lamp, comprising a base, a bottom of the base being provided with an anti-slip pad for preventing the desk lamp from slipping, an outer side of the base being provided with an illumination portion, an inner side of the illumination portion being provided with a positioning portion, and an inner side of the base being provided with a connection portion, wherein the illumination portion comprises: a support frame movably plugged into the interior of the base, an inner side of the support frame being provided with a connector, the connector being snap-fitted to the inner side of the support frame; a light-transmitting plate being snap-fitted to the inner side of the support frame, the light-transmitting plate being provided with fill light beads, the fill light beads being fixed to the interior of the support frame. Although the above patent can adjust the lighting area, in actual use, each joint is independent of each other. When adjusting the angle of the LED lamp, the user needs to adjust each joint one by one and fix it by tightening bolts or buckles. Since there is no linkage or adaptive structure between the joints, one-button unlocking and free deformation of the overall posture cannot be achieved, resulting in difficulty for the user to quickly reach the ideal lighting position. Each adjustment requires multiple loosening and tightening operations, which is time-consuming and affects the use effect.

[0004] The present invention aims to solve the problems existing in the above patents. To this end, a flexibly adjustable LED desk lamp is proposed, which can freely and quickly adjust the lighting angle, height and lighting direction, reduce operation time and improve usage effect. Summary of the Invention

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0030] Example: A flexible adjustable LED desk lamp, please refer to Figures 1-6As shown, it includes a base 1 and a supporting ball seat 2 fixed to the right side of the top of the base 1, the top of the supporting ball seat 2 is rotatably connected to the joint I 3, the top of the joint I 3 is rotatably connected to the joint II 4, the tail end of the joint II 4 is rotatably connected to the joint III 5, the left end of the joint III 5 is rotatably connected to the LED light 6, and the joint II 4 is symmetrically connected to the corrugated cover 7. The left side of the left corrugated cover 7 is fixedly connected to the right side of the joint III, and the right side of the right corrugated cover 7 is fixedly connected to the upper part of the joint I. The corrugated cover 7 can block foreign debris to prevent the attachment of debris from affecting the rotation between the joints I 3, the joints II 4 and the joints III 5. It also includes an arc splint 8, a connecting spring 9, a button 10, an electromagnet 11, a trigger assembly and a switching assembly. The lower part of the joint I 3, the right side of the joint II 4 and the right side of the joint III 5 are all symmetrically rotatably connected to the arc splint 8. The three groups of arc splints 8 are respectively connected to the joints I 3, the joints II 4 and the joints III 5. The ends of the joints Ⅰ3, Ⅱ4 and Ⅲ5 are in contact, and a connecting spring 9 is connected between the inner sides of the front and rear arc-shaped splints 8. Trigger components are provided on the inner sides of the joints Ⅰ3, Ⅱ4 and Ⅲ5. When the trigger component is operated, the trigger component can drive the arc-shaped splint 8 to swing outward. The positions of the inner sides of the joints Ⅰ3, Ⅱ4 and Ⅲ5 near the arc-shaped splint 8 are all embedded and fixed with electromagnets 11. Buttons 10 are fixed symmetrically on the front and back of the outer side of the joint Ⅲ5. The button 10 and the electromagnet 11 are electrically connected through a control module. The button 10 controls the electromagnet 11 to start through the control module, and the electromagnet 11 drives the trigger component to operate, so that the trigger component drives the arc-shaped splint 8 to swing outward to loosen the joints Ⅰ3, Ⅱ4 and Ⅲ5. Switching components are provided on the base 1 and the joint Ⅲ5. When the switching component is operated, the switching component can loosen the LED light 6 for position switching.

[0031] See also Figure 3 As shown, the trigger assembly includes a guide rod 12, an iron plate 121 and an inclined plate 122. The inclined plates 122 are fixedly connected to the left sides of the inner sides of the front and rear arc-shaped splints 8. The guide rods 12 are symmetrically connected to the inner sides of the joints I3, II4 and III5 in a front-to-back sliding manner. An iron plate 121 is fixedly connected between the ends of the front and rear guide rods 12. The iron plate 121 corresponds to the electromagnet 11. The front and rear sides of the iron plate 121 are in contact with the front and rear inclined plates 122 respectively. When the iron plate 121 moves to the left, the iron plate 121 can drive the inclined plate 122 to swing outward.

[0032] See also Figure 4-Figure 6As shown, the switching assembly includes a pressure block 13, a trigger assembly, a mounting seat 132 and a suction cup 133. A suction cup 133 is placed on the left side of the top of the base 1. The outer side of the suction cup 133 is fixedly connected to the mounting seat 132. The mounting seat 132 is circumferentially and evenly spaced from the left side of the joint III 5. There are four pressure blocks 13 in sliding connection. The upper pressure block 13 contacts the shaft of the LED lamp 6. The pressure block 13 can fix the LED lamp 6. An arc hole 134 is opened on the inner side of the pressure block 13. The arc hole 134 is tilted. The joint III 5 and the mounting seat 132 are evenly spaced. A trigger assembly is provided. When the trigger assembly is operated, the trigger assembly can drive the pressure block 13 to move; the driving assembly includes a driving ring 131 and a driving rod 1311. The left side of the outer side surface of the joint III 5 and the upper part of the outer side surface of the mounting seat 132 are both rotatably fitted with a driving ring 131. Four driving rods 1311 are fixedly connected to the driving ring 131 at uniform intervals along the circumferential direction. The driving rod 1311 is slidably connected to the arc hole 134. When the driving rod 1311 rotates, the driving rod 1311 can drive the pressure block 13 to move through the arc hole 134.

[0033] First, place the device on the desktop with the base 1 in contact with the desktop, and then press the button 10. The button 10 controls the electromagnet 11 to start through the control module. The electromagnet 11 starts and moves the iron plate 121 through magnetic attraction. The iron plate 121 moves and comes into magnetic contact with the electromagnet 11. The iron plate 121 moves and pushes the front and rear inclined plates 122 to swing outward. The inclined plates 122 drive the front and rear arc splints 8 to swing outward a suitable distance. The connecting spring 9 is stretched, and the front and rear arc splints 8 swing outward to loosen joints I3, II4 and III5, and the swing distance of the arc splint 8 will not completely loosen joints I3, II4 and III5, so that joints I3, II4 and III5 can rotate, and then pull joint III5 to drive the LED lamp 6 to move. At the same time, joint III5 can move at will through joints I3 and II4. In this way, the LED lamp can be flexibly made to move through joints I3, II4 and III5. 6 moves, and then continue to pull the LED light 6 to adjust the angle, height and lighting direction according to actual needs. When the position of the LED light 6 is adjusted, stop pulling the joint III 5, the LED light 6 stops moving, and release the button 10. The button 10 controls the electromagnet 11 to be closed through the control module, and the electromagnet 11 stops sucking the iron plate 121. Due to the action of the connecting spring 9, the front and rear arc-shaped splints 8 swing inward and reset to continue to fix the joint I3, joint II4 and joint III5, and the LED light 6 can be started. The LED light 6 accurately illuminates the working area to reduce eye fatigue and visual interference. At the same time, the corrugated cover 7 can cover the rotation between the joint II4 and the joint I3 and the joint III5 to prevent debris from falling from the rotation between the joint II4 and the joint I3 and joint III5 and affecting subsequent use, thereby ensuring the smooth use of the joint I3, joint II4 and joint III5. When the LED light 6 is not needed, turn off the LED light 6. This is repeated, and whenever the position of the LED lamp 6 needs to be adjusted, the button 10 is pressed to cause the arc-shaped splint 8 to loosen joints I3, II4, and III5, and the LED lamp 6 can be flexibly moved through joints I3, II4, and III5. In this way, by swinging the arc-shaped splint 8, it is possible to quickly unlock and lock, and the lighting angle, height, and lighting direction can be freely and quickly adjusted, reducing operation time and thus improving the use effect.When the LED lamp 6 needs to be used in an inclined or vertical placement area, first twist the upper drive ring 131 forward, and the upper drive ring 131 forward rotation drives the upper drive rod 1311 forward rotation, and the upper drive rod 1311 forward rotation drives the upper four pressing blocks 13 to move outward through the arc hole 134, and the upper four pressing blocks 13 move outward to loosen the shaft of the LED lamp 6, stop twisting the upper drive ring 131 forward, and the upper pressing block 13 also stops moving outward first, and then remove the LED lamp 6 from the joint III 5, and then twist the lower drive ring 131 to rotate, and the lower drive ring 131 drives the lower drive rod 1311 to rotate, and the lower drive rod 1311 drives the lower pressing block 13 to move outward to the maximum stroke through the lower arc hole 134, and stop twisting the lower drive ring 131. By rotating the square driving ring 131, the LED lamp 6 can be placed in the mounting seat 132 and between the four pressing blocks 13 below. Then, the lower driving ring 131 is twisted to rotate in the opposite direction. The lower driving ring 131 drives the lower driving rod 1311 to rotate in the opposite direction. The lower driving rod 1311 drives the lower pressing block 13 to move inward through the lower arc hole 134 to contact the shaft of the LED lamp 6. The lower pressing block 13 clamps the shaft of the LED lamp 6, thereby fixing the LED lamp 6. Then, the suction cup 133 is picked up from the base 1. The LED lamp 6 can be fixed in any use position through the suction cup 133 for use. In this way, it can replace the function of the base 1, so that the LED lamp 6 can be used in an inclined or vertical placement area, and has high adaptability. Similarly, when the suction cup 133 is not needed, twist the rotating pressure block 13 of the driving ring 131 to loosen the LED lamp 6, put the LED lamp 6 back on the joint III 5, clamp the LED lamp 6 with the upper pressure block 13, and then put the suction cup 133 back on the base 1.

[0034] See also Figure 7 and Figure 8As shown, the flexibly adjustable LED desk lamp also includes a counterweight assembly installed on the base 1, the counterweight assembly includes a ring 14, a guide frame 141, a counterweight block 142, a cylinder 143, a rotating assembly and a pressure sensor 147, the inner side of the base 1 is connected to the ring 14 along the circumferential direction, the inner side of the ring 14 is fixedly connected to the guide frame 141, and the counterweight block 142 is slidably mounted on the guide frame 141. The counterweight block 142 can realize counterweighting of the base 1 at different positions, and the left side of the guide frame 141 is fixedly connected to the cylinder 143. The end of the telescopic rod of the cylinder 143 is fixedly connected to the left side of the counterweight block 142. The bottom of the base 1 is circumferentially rotated. Four pressure sensors 147 are fixedly connected at even intervals. The pressure sensors 147 are electrically connected to the cylinder 143 and the stepper motor 145 through a control module. A rotating assembly is provided between the base 1 and the ring 14. When the rotating assembly is in operation, the rotating assembly can drive the ring 14 to rotate; the rotating assembly includes an inner ring gear 144, a stepper motor 145 and a spur gear 146. The inner ring gear 144 is fixedly connected to the top of the ring 14 along the circumferential direction, and the stepper motor 145 is fixedly connected to the rear side of the top of the base 1. The output shaft end of the stepper motor 145 is fixedly sleeved with a spur gear 146, and the spur gear 146 is meshed with the inner ring gear 144.

[0035] When the base 1 is placed on the desktop, the pressure sensor 147 contacts the desktop, and the pressure sensor 147 detects the placement force of the base 1. After the position of the LED lamp 6 is adjusted, the pressure sensor 147 continues to detect the placement force of the base 1. When the force detected by one of the pressure sensors 147 is less than the set value, it means that the base 1 is unevenly stressed due to the position adjustment of the LED lamp 6 and is tilted. When the pressure sensor 147 controls the stepper motor 145 to start through the control module, the stepper motor 145 starts to drive the spur gear 146 to rotate, the spur gear 146 rotates to drive the inner ring gear 144 to rotate, the inner ring gear 144 rotates to drive the ring 14 to rotate, the ring 14 rotates to drive the guide frame 141 to rotate, and the guide frame 141 drives the counterweight block 142 and the cylinder 143 to rotate. When the counterweight 142 rotates to the position corresponding to the tilted base 1, the stepper motor 145 is turned off, the spur gear 146 stops driving the inner gear ring 144 to rotate, and the ring 14 stops driving the cylinder 143 and the counterweight 142 to rotate through the guide frame 141. Then the cylinder 143 is started, and the telescopic rod of the cylinder 143 extends, driving the counterweight 142 to slide within the guide frame 141. When the counterweight 142 moves to the position where the base 1 tilts, due to its weight, the counterweight 142 applies pressure to the base 1, thus stably placing the base 1 in the placement area. The cylinder 143 is turned off, the counterweight 142 stops moving, and the LED lamp 6 can be used. This process is repeated. Each time the position of the LED lamp 6 is adjusted, the counterweight 142 can counterbalance the base 1, ensuring that the base 1 is placed stably. In this way, the tilting of the base 1 can be prevented, causing the entire device to tilt and fall, affecting the use of the LED lamp 6, thereby ensuring the normal use of the LED lamp 6.

[0036] See also Figure 9 As shown, the flexibly adjustable LED desk lamp also includes a rubber sleeve 15. Four rubber sleeves 15 are fixed to the bottom of the base 1 at evenly spaced intervals along the circumference. The rubber sleeves 15 are mounted on the pressure sensor 147. The rubber sleeves 15 can increase the friction between the base 1 and the desktop.

[0037] When the base 1 is placed on a table, the rubber sleeve 15 contacts the table, and the rubber sleeve 15 can increase the friction with the table, thus further making the base 1 more firmly placed.
