Description

Technical Field

[0001] This utility model belongs to the field of lighting technology, specifically relating to a multifunctional folding table lamp. Background Technology

[0002] A multifunctional folding desk lamp disclosed in reference application number CN202121506893.9 includes a lamp head, a lamp holder, and a lamp frame. One end of the lamp frame is connected to the lamp holder, and the other end is connected to the lamp head. The lamp frame includes several support rods, which are rotatably connected to each adjacent pair of support rods to form the lamp frame. The lamp holder has a lamp holder rotating component to realize the rotation of the lamp holder. The lamp head has a lamp head rotating component at its connecting end to realize multi-angle rotation of the lamp head. Through the above structural improvements, multi-angle rotation of the lamp head, rotation between the support rods, and rotation of the entire desk lamp are realized, expanding the lighting angle and lighting range of the desk lamp, making the desk lamp suitable for different application scenarios and improving the versatility of the desk lamp. At the same time, since the support rods can be folded after mutual rotation, the lamp frame can be folded when the desk lamp is not in use to reduce the space occupied.

[0003] However, the technical solution uses a "dual-axis + single-light source" structure, which has two significant shortcomings: First, the mechanical linkage mechanism of the dual-axis results in blind spots in the illumination coverage of the light source in some angle ranges, making it impossible to achieve uniform illumination across the entire angle. Second, the single-light source architecture lacks a mechanical design for optical focusing, and can only improve the overall illuminance through simple brightness adjustment. It cannot achieve precise focusing in local areas, nor can it enhance the brightness of specific areas through multi-light source collaboration. As a result, in scenarios requiring high-concentration lighting, brightness adjustment alone cannot meet the user's needs for lighting accuracy and layering. Utility Model Content

[0004] In order to overcome at least some of the shortcomings of the prior art, this utility model provides a multifunctional folding table lamp.

[0005] The technical solution provided by this utility model is as follows: A multifunctional folding desk lamp includes a desk lamp body and a folding lamp head. The desk lamp body includes a column and a base. The column is connected to the base. The folding lamp head is installed on the desk lamp body.

The vertical displacement component is installed on the desk lamp body. The horizontal displacement component is installed on the vertical displacement component. The rotating component is horizontally connected to the horizontal displacement component. The light source is installed on the rotating component.

[0006] Furthermore, the vertical displacement assembly includes a first guide rail, a first slider, a first moving stage, and a first horizontal bar. The first guide rail is fixed to the column, the first slider is fitted onto the first guide rail, the first moving stage is connected to the first slider, and the first horizontal bar is fixed to the first moving stage.

[0007] Furthermore, the horizontal displacement assembly includes a second guide rail, a second slider, a second moving stage, and a second horizontal rod. The second guide rail is fixed on the first horizontal rod, the second slider is fitted on the second guide rail, and the second moving stage is mounted on the second slider.

[0008] Furthermore, the rotating assembly includes a first rotating shaft, a second rotating shaft, a third rotating shaft, a fourth rotating shaft, a first rotating rod, a second rotating rod, a third rotating rod, and a tension knob. The second horizontal rod is connected to the first rotating rod via the first rotating shaft. The end of the first rotating rod away from the second moving platform is connected to both the second rotating rod and the third rotating rod via the second rotating shaft. The end of the second rotating rod away from the second rotating shaft is connected to the first light source via the third rotating shaft. The end of the third rotating rod away from the second rotating shaft is connected to the second light source via the fourth rotating shaft.

[0009] Furthermore, the light source includes a first light source and a second light source, the first light source being connected to the second rotating rod, and the second light source being connected to the third rotating rod.

[0010] Furthermore, the column includes a switch column, a transition column, a slide rail column, and a limit head. The switch column is mounted on the base, the switch column is connected to the slide rail column through the transition column, and the limit head is mounted on the top of the slide rail column.

[0011] Furthermore, the end of the slide rail column connected to the limiting head is provided with a displacement groove, and the first guide rail is installed in the displacement groove.

[0012] Furthermore, the transition column is a gradually tapering frustum structure, and the cross-section of the transition column smoothly tapers from the end connected to the switch column to the end connected to the slide rail column.

[0013] Furthermore, the first horizontal bar is a channel steel structure.

[0014] Furthermore, the switch post is equipped with a brightness adjustment knob, and the outer surface of the brightness adjustment knob is provided with anti-slip texture.

[0015] The beneficial effects of this utility model are as follows: This utility model adopts a mechanical linkage structure of "dual moving axes + dual rotating axes". The dual moving axes can realize the lamp body to move in a wide range of positions in the horizontal and vertical directions, and the dual rotating axes can precisely control the illumination angle of the light source. The linkage between the two can not only achieve full-area lighting without dead angles on the desktop, but also have the ability to be stably locked in any position. This utility model adopts a "dual light source" light source architecture. The dual light source structure can effectively improve the uniformity of desktop illumination through main and secondary coordination or zone dimming, solve the drawbacks of single light source being too bright in the center and dark at the edges, and support color temperature and brightness adjustment. It can switch between multiple lighting modes, which can not only enhance the brightness of key areas through dual light source coordination, but also reduce visual fatigue through mode adaptation. This utility model has achieved significant improvements in lighting functionality, adjustment accuracy and user experience. Attached Figure Description

[0025] See Figures 1 to 6 This embodiment discloses a multifunctional folding desk lamp, including a desk lamp body 1 and a folding lamp head 2. The desk lamp body 1 includes a column 11 and a base 12, with the column 11 and the base 12 fixedly connected. The folding lamp head 2 is mounted on the desk lamp body 1. The folding lamp head 2 includes a vertical displacement component 21, a horizontal displacement component 22, a rotating component 23, and a light source 24. The vertical displacement component 21 is mounted on the column 11 of the desk lamp body 1, the horizontal displacement component 22 is mounted on the vertical displacement component 21, the rotating component 23 is connected to the horizontal displacement component 22, and the light source 24 is mounted on the rotating component 23. The components work together precisely to achieve flexible adjustment of the lighting position and angle.

[0026] In this embodiment, the vertical displacement component 21 includes a first guide rail 211, a first slider 212, a first moving platform 213, and a first horizontal rod 214. The first guide rail 211 is fixed to the column 11 by symmetrically distributed screws. The screws are evenly distributed to ensure that the guide rail is firmly fixed and the force is balanced. The first slider 212 is fitted onto the first guide rail 211 to form a precise clearance fit. The clearance is reasonably controlled to ensure smooth sliding without obstruction and to avoid significant shaking, ensuring stable and reliable vertical movement. The first moving platform 213 is fixedly connected to the first slider 212. The connection surface is precision machined to ensure high flatness, ensuring uniform force transmission at the connection point, no local stress concentration, and a stable connection that is not easy to loosen. The first horizontal rod 214 is fixed onto the first moving platform 213. The connection structure is tight and can stably drive the entire folding lamp head 2 to move back and forth vertically along the first guide rail 211. The height adjustment range covers from the lowest point of the desktop to the highest point where the user can comfortably read, fully adapting to the height needs of users of different heights and various usage scenarios.

[0027] In this embodiment, the horizontal displacement component 22 includes a second guide rail 221, a second slider 222, a second moving platform 223, and a second horizontal rod 224. The second guide rail 221 is fixed to the first horizontal rod 214 by evenly distributed bolts. The bolts are installed precisely to ensure that the guide rail and the horizontal rod fit tightly without loosening or offset. The second slider 222 is fitted onto the second guide rail 221 to form a tight sliding fit. The mating surfaces make full contact, and the sliding process is smooth without jamming or obvious friction noise. The second moving platform 223 is installed on the second slider 222. The installation structure is compatible, the connection is firm and not easy to loosen, and it ensures that the components move synchronously without relative offset during horizontal movement. When the second slider 222 slides along the second guide rail 221, it can smoothly drive the second moving platform 223 and the subsequent rotating component 23 and light source 24 to move horizontally. The adjustment range can cover the entire lighting area of ​​the desktop. The vertical displacement component 21 can drive the horizontal displacement component 22, the rotating component 23 and the light source 24 to move vertically as a whole. The horizontal displacement component 22 can independently drive the rotating component 23 and the light source 24 to move horizontally. The two do not interfere with each other. Through the combination of independent adjustment, the folding lamp head 2 can be flexibly adjusted in three-dimensional space, ensuring that the light source 24 can be accurately aligned with different lighting areas, adapting to various usage scenarios such as desktop reading, manual operation, and local supplemental lighting. The lighting range can be quickly adjusted without moving the entire desk lamp.

[0028] In this embodiment, the rotating assembly 23 includes a first rotating shaft 231, a second rotating shaft 232, a third rotating shaft 233, a fourth rotating shaft 234, a first rotating rod 235, a second rotating rod 236, a third rotating rod 237, and a tension knob 238. The second horizontal rod 224 is rotatably connected to the first rotating rod 235 via the first rotating shaft 231. The first rotating shaft 231 has a built-in damping structure composed of a spring and a friction plate, with an appropriate damping force to meet the needs of easy rotation adjustment while ensuring stable stopping after rotation and preventing automatic drooping due to gravity. The end face of the first rotating rod 235 away from the second moving platform 223 has a mounting groove, through which the second rotating shaft 232 passes and is rotatably connected to the first rotating rod 235. The second rotating rod 236 and the third rotating rod 237 are symmetrically installed on both sides of the first rotating rod 235, and one end of each is sleeved on the second rotating shaft 232. This forms a coaxial symmetrical rotation structure with one main (first rotating rod 235) and two auxiliary (second rotating rod 236 and third rotating rod 237). The second rotating rod 236 and the third rotating rod 237 are located on both sides of the first rotating rod 235, and can be independently adjusted at multiple angles around the second rotating axis 232 without interfering with each other during rotation, making adjustment flexible and convenient. The end of the second rotating rod 236 away from the second rotating axis 232 is rotatably connected to the first light source 241 through the third rotating axis 233, and the end of the third rotating rod 237 away from the second rotating axis 232 is rotatably connected to the second light source 242 through the fourth rotating axis 234. The precise coordination of multiple rotating axes, through coordinated action, allows the first light source 241 and the second light source 242 to achieve flexible adjustment at multiple angles and directions, enabling them to be individually aimed at different lighting areas or simultaneously focused on the same position, fully meeting diverse lighting needs.

[0029] In this embodiment, the light source 24 includes a first light source 241 and a second light source 242. The first light source 241 is connected to the second rotating rod 236, and the second light source 242 is connected to the third rotating rod 237. The connection structure is compatible, and the light source is stable after installation without loosening or shifting, ensuring accurate lighting direction.

[0030] In this embodiment, the column 11 includes a switch column 111, a transition column 112, a slide rail column 113, and a limiting head 114. The switch column 111 is installed at the edge of the base 12, with precise installation and a tight connection to the base. The base 12 is made of high-density material and provides stable support for the entire lamp through its own weight, effectively preventing it from tipping over due to collisions or touches during use. The support effect is reliable. The switch column 111 and the slide rail column 113 are connected through the transition column 112, with a tight connection structure and smooth force transmission. The column 11 and the base 12 are fixedly connected by bolts, with the bolts distributed reasonably and the connection points hidden in the base. The internal structure of base 12 ensures a neat and aesthetically pleasing appearance while providing a stable mounting base for the folding lamp head 2 through the tightness of the threaded engagement. This mounting position also increases the gravitational arm of base 12, thereby more effectively balancing the overturning moment generated by the folding lamp head 2, significantly improving the lamp's anti-overturning capability. Even when the folding lamp head is fully extended, it remains stable. The limiting head 114 is securely mounted on the top of the slide rail column 113, and its diameter is larger than the outer diameter of the slide rail column 113, forming an effective blocking structure. This precisely prevents the first slider 212 from detaching from the top of the first guide rail 211, avoiding accidental detachment of the folding lamp head 2 and improving safety.

[0031] In this embodiment, the end of the slide rail column 113 connected to the limiting head 114 is provided with a displacement groove 1131. The groove has a regular structure and no burrs on the edges. The first guide rail 211 is installed in the displacement groove 1131. The installation position is accurate and it fits tightly with the groove. The length of the displacement groove 1131 is precisely matched with the vertical movement stroke of the folding lamp head 2, ensuring that the folding lamp head can move smoothly within a preset range. The groove wall is polished and has a smooth surface, which can reduce frictional resistance during movement and ensure smooth sliding.

[0032] Preferably, the transition column 112 is a gradually tapered frustum structure. The cross-section of the transition column 112 smoothly tapers from the end connected to the switch column 111 to the end connected to the slide rail column 113, with a natural gradual transition and no obvious sharp edges. This structural design not only makes the overall lines of the column 11 smoother and more beautiful, but also optimizes the material distribution and reduces the amount of material used in the slide rail column 113 while ensuring the support strength of the slide rail column 113, thus significantly reducing production costs.

[0033] Preferably, the first horizontal bar 214 is a channel steel structure with a regular channel structure and an opening facing the second moving platform 223. The inner wall of the channel is polished, with a smooth surface without burrs and high flatness, which can minimize the frictional resistance during sliding and ensure smooth horizontal movement.

[0034] Preferably, the switch post 111 is provided with a brightness adjustment knob 1111. The knob has a regular structure and is tightly connected to the switch post. The outer surface of the brightness adjustment knob 1111 is provided with anti-slip texture. The texture is uniform, clear, and of moderate depth, which can improve the friction during operation and facilitate user rotation adjustment. The switch post 111 integrates a control circuit with a reasonable circuit layout. By rotating the brightness adjustment knob 1111, the start / stop and brightness adjustment of the first light source 241 and the second light source 242 can be precisely controlled. The adjustment response is sensitive and the control effect is reliable.

[0035] In this embodiment, the second rotating shaft 232 is provided with a tension knob 238. The tension knob 238 is threadedly connected to the second rotating shaft 232, with tight thread engagement, smooth adjustment, and no jamming. Since the second rotating shaft 232 is the core component for adjusting the angles of the first light source 241 and the second light source 242, the user needs to frequently rotate it to adjust the lighting direction during use. Traditional friction damping structures rely solely on initial preload to provide damping. After long-term use, the contact surface between the friction plate and the rotating shaft will gradually wear due to repeated friction, resulting in an increased gap between the contact surfaces, a decrease in damping force, and easy loosening of the light source angle, affecting the user experience. The tension knob 238 is threadedly connected to the second rotating shaft 232. The knob 238 allows for adjustment of the preload force at any time depending on usage: When the light source angle needs to be adjusted, the user can rotate the knob 238 to precisely reduce the preload force, thereby reducing the friction between the friction plate and the second rotating shaft 232, making the rotation smoother and significantly reducing wear on the contact surface. After adjustment, rotating the knob 238 in the opposite direction can precisely increase the preload force, firmly fixing the position of the second rotating shaft 232 through the clamping force, ensuring that the light source angle remains stable and will not shift due to slight touch. This adjustable preload force structure effectively solves the problems of rapid wear and short lifespan of friction damping structures, improving the durability and stability of the desk lamp.

[0036] Preferably, the outer circumferential surface of the tension knob 238 is covered with a layer of anti-slip silicone. The silicone layer is evenly distributed and fits tightly to the knob, eliminating the risk of it falling off. This anti-slip layer is made of highly elastic food-grade silicone, which is soft in texture. The surface of the tension knob 238 is pressed with evenly distributed diamond-shaped anti-slip patterns. The patterns are clear and regular, which can significantly increase the coefficient of friction between the hand and the tension knob 238, making it less likely for the user to slip when rotating the tension knob 238. It can be operated stably even when the hands are wet. At the same time, the silicone material has a good soft touch, which can reduce discomfort during hand operation and improve the user's operating comfort.

[0037] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
