Description

Technical Field

[0001] The invention relates to the technical field of eye protection desk lamps, and in particular to a liftable three-dimensional eye protection desk lamp. Background Art

[0002] The eye-protection desk lamp mainly consists of two parts: the light source and the lamp. The lamp head is usually a light source with relatively good light quality. The lamp is a lampshade that can improve the uniformity of light distribution and weaken or reduce glare, as well as a driving circuit that provides current to the light source. In order to improve the convenience of using the eye-protection desk lamp, the existing eye-protection desk lamp can change the placement of the light source in multiple directions and angles.

[0003] A Chinese utility model patent with authorization announcement number CN208107736U discloses a radiation-free eye protection desk lamp, including a lamp holder, a connecting tube and an LED lampshade. A radiation-free eye protection desk lamp is designed with a connecting tube using a hardware hose, which facilitates the adjustment of the angle of the desk lamp. The presence of an anti-glare film and a soft light panel, as well as the use of a blue-light-reducing LED lamp, makes the light less glaring and effectively protects the user's eyes; the USB charging port can provide a charging port for the user of the desk lamp, bringing convenience to the user. In short, the radiation-free eye protection desk lamp has a reasonable structural design, is easy to use, does not hurt the eyes, and is suitable for promotion and use. The device is fixed by a placement method, which increases the footprint of the device to a certain extent.

[0004] In response to the above problems, a liftable three-dimensional eyewear desk lamp is disclosed in a Chinese invention patent with authorization announcement number CN113503503B. Through the setting of a fixing clamp, when the user needs to quickly install the device, the fixing sleeve, steering seat, steering seat, placement plate, threaded rod and adjusting knob work together. The user can first put the fixing clamp on one side of the object to be fixed, and then turn the adjusting knob to drive the threaded rod to move downward. The combination of the limiting slide groove and the fixing plate allows the fixing plate to move up and down better. In the process of the threaded rod moving downward, the bottom of the fixing plate can be made close to the surface of the fixed object, thereby completing the fixation, thereby improving the applicability of the structure.

[0005] However, the clamping structure used for fixing has great restrictions on the desktop, and is difficult to be applied to a thick desktop or a desktop without installation space in the front.

[0006] A Chinese invention patent with the authorization announcement number CN111271637B discloses a desk lamp for intelligently correcting sitting posture, which solves the problem that the current desk lamp has a single function and cannot provide prompts for incorrect sitting postures. The desk lamp comprises a barrel body, and a partition is connected to the lower side of the barrel body. The present invention, through the arrangement of the barrel body, the partition, the lower connecting seat, the first swing arm, the second swing arm, the upper connecting seat, the lamp panel, the flashing lamp and the sitting posture correction component, when a person is in use, when the sitting posture is incorrect and the top hat contacts or the head is too close to the desktop to trigger the ultrasonic sensor, the Bluetooth The desk lamp alarm is controlled under the feedback of the communication. When the collision top cap and the ultrasonic sensor are triggered at the same time, the desk lamp will alarm and flash the light to remind people to adjust the correct sitting posture. The sitting posture correction component of the invention contains a vibration module, which can be used alone when silence is required. After use, the touch rod of the invention can be rotated around the connection part and then retracted into the sitting posture correction component. The collision top cap is engaged with the card block to store the sitting posture correction component, and then the lamp panel is folded and stored in the barrel. Such a structure enables the desk lamp to be folded and stored, making the desktop tidy.

[0007] However, although the above-mentioned disclosed technical solution can correct the sitting posture, it is to directly add a detection device for sitting posture detection, which is essentially equivalent to directly using a human posture detector for monitoring. It has a complex structure and relatively high production cost, which is not conducive to large-scale production. In view of the problems existing in the above-mentioned prior art, this application is proposed. Summary of the invention

[0008] In order to overcome the technical defects of the prior art, the present invention provides a liftable three-dimensional eye-protection desk lamp, which has the advantages of comprehensive lighting, diverse functions, and the ability to correct human sitting posture.

DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1-Figure 11 shown.

[0035] Example 1 The present embodiment provides a liftable three-dimensional eye protection desk lamp, comprising a base 1, a fixed tube 2 rotatably arranged on the top of the base 1, and a telescopic rod 3 sleeved in the fixed tube 2 through a lifting control structure. The annular light source consists of a shell, a plurality of lamp beads arranged in the shell, and a reflector, a light guide plate and a diffuser plate arranged in sequence below the lamp beads. The reflector, the light guide plate and the diffuser are used for multiple diffusion processing of light. A light control switch 13 is arranged on the side wall of the fixed tube 2. A mounting bracket 4 is fixedly arranged on the top of the telescopic rod 3, and a rotating bracket 5 is arranged in the mounting bracket 4. One end of the rotating bracket 5 is connected to a ring-shaped light source 7 through a lamp pole 6, which is the basic structure of the eye protection desk lamp. The telescopic rod 3 can carry the upper ring-shaped light source 7 to rise and fall synchronously under the control of the lifting control structure. The setting of the rotating bracket 5 can further increase the flexibility of the ring-shaped light source 7, so that the ring-shaped light source 7 can adjust the height and inclination angle according to actual needs.

[0036] A multi-point synchronous adsorption fixing mechanism 10 is provided on the base 1. The adsorption plates 101 of the multi-point synchronous adsorption fixing mechanism 10 are respectively located at the bottom of the four corners of the base 1, and can be evenly fixed at various points of the base 1. At the same time, the loading and unloading operations are controlled by switches, which can realize fast one-key fixation and one-key contact fixation, which is convenient and flexible. A self-fixable mobile frame 8 is sleeved on the fixed cylinder 2. Two deployable lighting posture correction integrated components 9 are symmetrically arranged on the back of the mobile frame 8. After being deployed, they form an illumination environment in three directions together with the annular light source 7. With the cooperation of the three light sources, comprehensive lighting illumination can be formed to ensure that the area below the desk lamp is fully illuminated, so that both sides of the user's hands can be illuminated, and the eye protection effect is better. At the same time, the two deployable lighting posture correction integrated components 9 can be deployed to both sides respectively. After being deployed, on the one hand, they can be illuminated in multiple directions On the other hand, the infrared ranging structure can detect the distance to various parts of the human body in front. If the distance between some limbs is too short, it means that the human body may be bowing too much or the shoulders may sink, which is not good for human health. At this time, the buzzer 915 emits a prompt sound to remind the user to adjust the sitting posture in time, and replaces the high-cost posture detector with a simple infrared ranging structure. The small size is suitable for table lamp installation, and the cost is low, suitable for large-scale production, and has high application value. The first motor 401 is installed on the mounting bracket 4, and the output shaft of the first motor 401 is fixedly connected to the rotating axis of the rotating bracket 5, which is used to control the inclination angle of the ring light source 7. The rotating bracket 5 can be manually adjusted during use, and can also be controlled by the first motor 401. It has high flexibility and is convenient for regulating the inclination angle of the ring light source 7.

[0037] Specific as Figure 5As shown, the multi-point synchronous adsorption fixing mechanism 10 is composed of four adsorption plates 101 respectively arranged at the four corners of the bottom of the base 1 and a hollow cylinder 102 fixedly arranged inside the base 1. The top of each adsorption plate 101 is connected to the middle area of ​​the hollow cylinder 102 through an air guide tube 104. An electric telescopic rod 103 is also fixedly arranged in the base 1. The telescopic end of the electric telescopic rod 103 is connected to the piston built into the hollow cylinder 102. A loading and unloading control switch 12 is arranged on the side wall of the base 1 for controlling the extension and retraction of the electric telescopic rod 103. There are two loading and unloading control switches 12, which respectively control the extension and retraction of the electric telescopic rod 103. When it is used specifically, when the base 1 needs to be fixed, the base 1 is placed The suction cup 101 is then pulled outwards to lower the air pressure in the hollow tube 102, and the air in the suction cup 101 at the end of the air duct 104 is sucked in by the low air pressure, so that the suction cup 101 can be tightly attached to the desktop. Conventional technical means can also achieve this effect directly through a single suction cup 101, but it is more difficult to disassemble. The present application only needs to press the switch to control the electric suction cup 103 to extend, so that the piston pushes the air in the hollow tube 102 into the suction cup 101 through the air duct 104, so that there is no adsorption effect between the suction cup 101 and the desktop, and the disassembly is completed. The operation is simple and convenient, and the loading and unloading are very fast.

[0038] Specific as Fig. 9 As shown, the movable frame 8 is composed of a sliding frame 801 sleeved on the fixed cylinder 2 and an extension seat 802 fixedly arranged on the back of the sliding frame 801, the expandable lighting posture correction integrated component 9 is installed on the top of the extension seat 802, and a transversely penetrating screw 803 is installed in the extension seat 802, and a non-slip pad is arranged on the side of the screw 803 facing the fixed cylinder 2, and a rotating handle 804 is fixedly arranged on one end of the screw 803 located outside the extension seat 802. The expandable lighting posture correction integrated component 9 is carried by the movable frame 8, so that the expandable lighting posture correction integrated component 9 can move on the fixed cylinder 2 with the movable frame 8, so as to meet the needs of people of different heights when using the desk lamp, and has In order to ensure that the functions of the deployable lighting posture correction integrated component 9 can be fully and effectively applied, the optimal operating height should be at the user's shoulder, so that the infrared detection structure of the deployable lighting posture correction integrated component 9 can cover the upper part of the user's body after being deployed. When the mobile frame 8 is in use, when the screw 803 moves toward the outside of the fixed tube 2, the mobile frame 8 can be flexibly raised and lowered. When it needs to be fixed, it is only necessary to turn the screw 803 by rotating the handle 804 to move the screw 803 toward the side of the fixed tube 2 until the anti-slip gasket is pressed to the outer wall of the fixed tube 2. At this time, the mobile frame 8 can be effectively fixed by the friction between the anti-slip gasket and the outer wall of the fixed tube 2.

[0039] Specific as Fig.10 As shown, the deployable lighting posture correction integrated component 9 includes a transverse rotating frame 901 fixed on the top of the extension seat 802, a rotating connecting rod 902 installed in the transverse rotating frame 901, and an unfolding plate 903 fixedly arranged at one end of the rotating connecting rod 902. The transverse rotating frame 901 is embedded with a control motor whose output shaft is connected to the rotating connecting rod 902, an electric push rod 904 is installed in the unfolding plate 903, and a third motor 905 is installed at the telescopic end of the electric push rod 904. A multi-functional base 906 is connected to the output shaft of the third motor 905, and a buzzer 915 is fixedly arranged at the end of the multi-functional base 906. The transverse rotating frame 901 remains fixed, and the rotating connecting rod 902 can rotate in the transverse rotating frame 901, and is rotated and adjusted by the embedded control motor. When it is turned to the outside and is horizontal, it is in the unfolded state, and when it is turned to the inside and is vertical, it is in the folded state. When folded, it occupies less space, has high aesthetics, and is easy to carry and pack.

[0040] A strip light source 907 is arranged on the side wall of the multifunctional base 906. The position of the multifunctional base 906 can be flexibly adjusted by retracting the electric push rod 904 and rotating the third motor 905, so that when the unfolded plate 903 is turned to the horizontal, the strip light source 907 can be rotated to the bottom to illuminate the user's desktop, and cooperate with the ring light source 7 to realize multi-dimensional lighting, reduce lighting blind spots, and have a better eye protection effect. A speaker 908 that can be connected to a Bluetooth external device is arranged on the side wall of the multifunctional base 906 facing away from the strip light source 907. The setting of the speaker 908 is intended to enhance the functionality of the two deployable lighting posture correction integrated components 9. Since the two deployable lighting posture correction integrated components 9 are located on both sides when in use, the setting of the speaker 908 can make the audio playback more three-dimensional and the experience is better. The side wall of the multifunctional base 906 is also fixed Two paper clamping pieces 909 are fixedly provided, and two movable push rods 910 are inserted into the paper clamping piece 909 on one side. The two movable push rods 910 are connected to a toggle piece 912 together. The toggle piece 912 and the paper clamping piece 909 are fixedly connected by an elastic contraction rod 911. When the paper clamping piece 909 is in use, it is only necessary to manually pull the toggle piece 912 outwards so that the movable push rod 910 is away from the gap between the two paper clamping pieces 909. At this time, the paper to be clamped is placed in the gap, and then the restriction on the toggle piece 912 is released. At this time, the toggle piece 912 can push the two movable push rods 910 into the gap under the pull of the elastic contraction rod 911 to fix the paper. In normal use, the paper is just below the strip light source 907, so that the content on the paper can also be fully illuminated. The design is reasonable and practical.

[0041] Specific as Fig.11As shown, a strip-shaped inner groove is provided on the front side of the unfolding plate 903, and a rotation adjustment motor is embedded in the strip-shaped inner groove. A rotation detection strip 913 is connected to the output shaft of the rotation adjustment motor. A plurality of infrared ranging light sources 914 and an infrared receiver for receiving reflected infrared light are arranged in the rotation detection strip 913. The rotation of the rotation detection strip 913 can be controlled by the rotation adjustment motor, so that each infrared ranging light source 914 on the rotation detection strip 913 can illuminate the front area, and the reflected infrared light is used for ranging. Specifically, the rotation detection strip 913 also needs to have a data processing Specifically, when a person sits in front of a desk lamp, there is usually a certain distance between the person and the wall behind. Only the person maintains a relatively close distance. The data processor mainly monitors the data of this shorter distance. The infrared ranging light source 914 and the infrared receiver work continuously and transmit data to the data processor. When the data in a certain area of ​​the data processor is concentrated and reduced, while the data in other areas remains unchanged, it means that the user's sitting posture is unreasonable at this time, and there may be bending, lowering the head or sinking the shoulders. At this time, it is necessary to control the buzzer 915 to emit a prompt sound to remind the user to adjust the sitting posture in time.

[0042] Example 2 This embodiment further explains the lifting control structure in the fixed cylinder 2 on the basis of the embodiment 1. Figure 6 and Figure 7 As shown, the lifting control structure in the fixed cylinder 2 is specifically a second motor 201 fixed in the fixed cylinder 2 and a screw rod 202 fixed on the output shaft of the second motor 201. The screw rod 202 is threadedly connected to the telescopic rod 3. Two longitudinal limit sleeves 203 are also provided in the fixed cylinder 2. The telescopic rod 3 is sleeved on the two limit sleeves 203. The second motor 201 is turned on to control the rotation of the screw rod 202. The telescopic rod 3 cannot rotate under the restriction of the two limit sleeves 203 and the side walls of the fixed cylinder 2, and can only move up and down. Then, when the screw rod 202 rotates, it can be pushed up and down to carry the annular light source 7 above to rise and fall.
