DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described in connection with the drawings in the embodiments of the utility model.

[0026] The utility model embodiment provides a kind of intelligent lifting control light LED desk lamp,

[0027] As Figure 1 It is shown, including lamp holder 1, lampshade 2 and LED lamp group module, control circuit board is installed on lamp holder 1, the LED lamp group module is electrically connected with control circuit board, pressure sensor 3 is connected in the control circuit board, the hard bottom pipe 4 is integrally formed on the upside of lamp holder 1, the hard top pipe 5 is connected with the lower end of lampshade 2, lifting pipe is connected between hard bottom pipe 4 and hard top pipe 5, control circuit board can be used for adjusting the light intensity of LED lamp group module according to the feedback signal of pressure sensor 3.

[0028] As Figure 2 , Figure 3As shown, the lifting pipe includes a corrugated hose 6 and a silicone hose 7 sleeved on the outer wall of the corrugated hose 6. The lifting pipe can bend forward and backward to adjust the height of the lamp cover 2 and the LED lamp module, thereby adjusting the illumination range of the LED lamp module. When the lifting pipe is bent, the front side of the corrugated hose 6 and the silicone hose 7 are squeezed and contracted against each other, while the rear side is stretched and elongated, making the lifting pipe into a curved arc shape. The inner walls of the front and rear sides of the silicone hose 7 are provided with sliding guide grooves, and a sliding toothed belt 8 is inserted in the sliding guide grooves. An eccentric component 9 is rotatably connected to the lamp holder 1. The two ends of the sliding toothed belt 8 are fixed to the top of the lifting pipe, and the middle part extends downward and wraps around the eccentric component 9. Depending on the bending state of the lifting hose, the two ends of the sliding toothed belt 8 are fixed, the front side becomes shorter, and the rear side is extended, so that the middle part of the sliding toothed belt 8 wrapped around the eccentric component 9 slides. During the sliding process, it will drive the eccentric component 9 to rotate.

[0029] like Figure 6 As shown, the eccentric assembly 9 includes an eccentric shaft 91 rotatably connected to the lamp holder 1, a sliding gear 92 concentrically arranged with the eccentric shaft 91, and eccentric wheels 93 symmetrically arranged on both sides of the sliding shaft 91. The middle part of the sliding toothed belt 8 is engaged and wound around the sliding gear 92, and the eccentric wheel 93 abuts against the top of the conductive block.

[0030] like Figure 3 As shown, a guide cylinder 10 is fixed on the lamp holder 1. A conductive block 11 is slidably connected to the top of the guide cylinder 10. A pressure spring 12 is connected between the conductive block 11 and the pressure sensor 3. The rotation of the eccentric assembly 9 can press against the upper end of the conductive block 11 according to the change of the outer edge of the eccentric wheel 93, so that the conductive block 11 slides in the guide cylinder 10 and transmits the pressure to the pressure sensor 3 through the pressure spring 12.

[0031] like Figure 3 , Figure 4 As shown, a connecting sleeve 13 is fixed between the rigid jacking pipe 5 and the lifting pipe hose. Both ends of the sliding toothed belt 8 are fixed to the lower end of the connecting sleeve 13. A compensation groove is provided on the front side of the connecting sleeve 13. A compensation slider 14 is slidably installed in the compensation groove. A compensation spring 15 is connected between the compensation slider 14 and the compensation groove. The front end of the sliding toothed belt 8 is fixed to the lower end of the compensation slider 14. The compensation spring 15 can be used to compensate for the displacement difference between the sum of the lengths of the front and rear sides of the lifting pipe hose in the vertical state and the sum of the lengths of the front and rear sides in the bent state, so as to avoid the sliding toothed belt 8 from being stretched or unable to bend due to the displacement difference.

[0032] Further configured, a sliding hole is provided on the rear side of the connecting sleeve 13, a push screw hole is provided on the upper side of the sliding hole, the inner diameter of the push screw hole is larger than the inner diameter of the sliding hole, a guide hole is provided on the lower side of the sliding hole, and an adjustment component is internally threaded into the push screw hole.

[0033] like Figure 5 As shown, the adjustment assembly includes an adjustment block 16 threaded into the feed screw hole, an adjustment push rod 17 integrally formed at the lower end of the adjustment block 16, and an adjustment slider 20 rotatably connected to the lower end of the adjustment push rod 17. The rear end of the sliding toothed belt 8 is fixed on the adjustment slider 20. The adjustment slider 20 is slidably installed in the guide hole. The adjustment block 16 can rotate and slide up and down in the feed screw hole. The adjustment push rod 17 can slide up and down under the action of the adjustment block 16, thereby pushing the adjustment slider 20 to rise and fall in the guide hole. The initial height of the sliding toothed belt 8 can be adjusted. During the adjustment process, the compensation spring 15 can provide the displacement required for adjustment.

[0034] like Figure 4 As shown, a limiting groove is formed on the outer wall of the adjusting push rod 17, and a rotating slot is formed on the side wall of the connecting sleeve 13, which communicates with the sliding hole. A rotating gear ring 18 is rotatably installed in the rotating slot. A limiting strip is provided on the inner wall of the rotating gear ring 18, which is in concave-convex fit with the limiting groove. The rotating gear ring 18 is slidably mounted on the outer wall of the adjusting push rod 17. An adjusting ring groove is formed on the outer wall of the adjusting push rod 17, which communicates with the rotating slot. An adjusting gear ring 19 is rotatably connected in the adjusting ring groove. The adjusting gear ring 19 and the rotating gear ring 18 mesh with each other.

[0035] Working principle:

[0036] In this invention, the rotating gear ring 18 can be driven to rotate in the rotating groove by rotating the adjusting gear ring 19. During the rotation, the limiting groove and the limiting strip limit each other, which can drive the overall rotation of the adjusting component. The adjusting block 16 can slide up and down the push screw hole. During the sliding process, the limiting strip and the limiting groove slide relative to each other, pulling the sliding gear belt 8 to slide in the sliding guide groove on the rear side. During the sliding process, the compensation spring 15 extends and retracts to compensate for the required displacement length. The sliding of the sliding gear belt 8 can cause the eccentric wheel 93 to rotate eccentrically through meshing. The outer edge of the eccentric wheel 93 abuts against the transmission block 11 and slides. The pressure spring 12 transmits the pressure change to the pressure sensor 3, thereby controlling the initial light intensity of the LED light group module.

[0037] During the adjustment of the lifting and lowering process, the sliding toothed belt 8 is manually bent to adjust the height of the lamp holder 1, thereby adjusting the illumination range of the light. During the bending process, the front side of the corrugated hose 6 and the silicone hose 7 of the lifting hose is compressed and shortened, while the rear side is stretched and lengthened. The extended rear side of the lifting hose will pull the excess part of the shortened front side of the sliding toothed belt 8 backward. Through the interaction between the sliding toothed belt 8 and the sliding gear 92, the eccentric wheel 93 is driven to rotate. The change of the outer edge of the eccentric wheel 93 can change the pressure on the pressure sensor 3, and the light intensity of the LED light module can be controlled by the control circuit board.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
