Description

Technical Field

[0001] The present invention relates to the technical field of foldable desk lamps, and in particular to a foldable desk lamp structure, a desk lamp comprising the foldable desk lamp structure, and a method. Background Art

[0002] Folding desk lamps offer flexibility, allowing for flexible rotation of the light's direction, ensuring on-demand illumination. They also offer ample illumination, a DC power supply, no flickering, and no electromagnetic radiation. They are energy-efficient, utilize a solid-state light source, and are resistant to mechanical vibration. Utilizing specialized technology, they achieve high light efficiency and low attenuation. As modern living spaces become more compact and multifunctional, folding lighting devices are becoming a mainstream market offering portability and adaptability. As a typical example, folding desk lamps meet basic lighting needs while also offering both adjustability and stability.

[0003] Existing technologies struggle to maintain dynamic balance. When unfolding the arms or strips, traditional folding desk lamps can shift their center of gravity due to the shifted weight distribution of the extended components, creating a "top-heavy" effect. This poses a risk of tipping, especially when the arms are extended significantly or adjusted at multiple angles. Existing technologies often employ fixed counterweights or thickened bases to compensate for this balance, but these solutions sacrifice lightweight and portability and fail to adapt to the dynamic balance requirements of varying unfolding angles. Summary of the Invention

[0004] (1) Technical problems solved

[0005] In response to the shortcomings of the prior art, the present invention provides a foldable desk lamp structure, a desk lamp including the foldable desk lamp structure, and a method thereof. The structure is characterized in that, under the action of the gravity of the auxiliary counterweight, the auxiliary counterweight descends and moves toward the base. The descending auxiliary counterweight cooperates with the main counterweight moving in the opposite direction to move the center of gravity of the desk lamp in the opposite direction of the extension of the light strip mounting rod, thereby avoiding the phenomenon of the center of gravity of the lamp shifting due to the extension of the light strip mounting rod during use. That is, through the linkage design of the main counterweight and the auxiliary counterweight, dynamic balance is achieved when the desk lamp is unfolded, and the top-heavy phenomenon is avoided. This solves the problem that when the traditional foldable desk lamp unfolds the lamp arm or light strip, the center of gravity shifts due to the change in the weight distribution of the extending components, resulting in the "top-heavy" phenomenon. In particular, there is a risk of tipping over when the lamp arm is greatly extended or adjusted at multiple angles. The prior art mostly uses fixed counterweights or thickened bases to compensate for the balance, but such solutions sacrifice the lightweight and portability of the equipment and cannot adapt to the dynamic balance requirements of different unfolding angles.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the present invention provides a foldable desk lamp structure and a desk lamp and method including the foldable desk lamp structure, which have the following beneficial effects:

[0019] 1. The foldable desk lamp structure extends to one side of the base through the lamp strip mounting rod. At the same time, the fan-shaped support column at the connection between the lamp strip mounting rod and the folding plate changes from contacting the traction rope with the round edge to contacting the traction rope with the side edge of the fan-shaped support column. That is, the traction rope reduces the length of the round edge of the fan-shaped support column, thereby causing one end of the traction rope to move toward the auxiliary counterweight block. Because the auxiliary counterweight block was previously released by the auxiliary counterweight unlocking mechanism, the auxiliary counterweight block drops and moves toward the base under the action of its gravity. The dropped auxiliary counterweight block cooperates with the main counterweight block moving in the opposite direction to move the center of gravity of the desk lamp in the opposite direction of the extension of the lamp strip mounting rod, thereby avoiding the phenomenon that the center of gravity of the lamp is shifted due to the extension of the lamp strip mounting rod during use. That is, through the linkage design of the main counterweight block and the auxiliary counterweight block, dynamic balance is achieved when the desk lamp is unfolded, avoiding the phenomenon of top-heavy.

[0020] 2. The foldable desk lamp structure supports the auxiliary counterweight by the support spring and support platform in the auxiliary counterweight unlocking mechanism, wherein the bottom of the support spring is fixed to the bottom of the mounting slide groove. When the folding plate moves toward the mounting vertical plate, the unlocking gear under the folding plate cooperates with the teeth on the lower surface of the moving groove, causing the unlocking gear to rotate, thereby driving the winding shaft to rotate, winding the unlocking rope, so that the other end of the unlocking rope pulls the support platform, compressing the support spring, thereby causing the bottom of the auxiliary counterweight to lose support, thereby completing the unlocking of the auxiliary counterweight.

[0021] 3. The foldable desk lamp structure is provided with a fan-shaped support tube and a fan-shaped support column at the end of the folding plate. When the folding plate and the light strip mounting rod are folded, the oblique side area of ​​the fan-shaped support tube and the oblique side area of ​​the fan-shaped support column overlap, so that the length required for the traction rope to pass around the overlapping part is reduced, and one end of the traction rope is fixed in the light strip mounting rod, and the other end is connected to the auxiliary counterweight block. At this time, since the auxiliary counterweight block is released from support, it moves toward the base under the action of the gravity of the auxiliary counterweight block, so that the center of gravity of the entire desk lamp is lowered; when the folding plate and the light strip mounting rod are unfolded, the fan-shaped area of ​​the fan-shaped support tube and the fan-shaped area of ​​the fan-shaped support column are close to each other, so that the traction rope will not pass around the fan-shaped area of ​​the fan-shaped support tube and the fan-shaped area of ​​the fan-shaped support column, that is, the required length of the traction rope is reduced, and under the action of the gravity of the auxiliary counterweight block, it moves toward the base, so that the center of gravity of the entire desk lamp is lowered, thereby providing high stability support in both folded and unfolded states.

[0022] 4. The foldable desk lamp structure is provided with a mounting disc which is rotated in the middle part above the base. The mounting vertical plate and the folding plate are all mounted on the mounting disc. When the mounting disc is rotated to adjust the lateral angle of the light strip mounting rod, the main counterweight block is always on both sides of the extended light strip mounting rod with the mounting vertical plate as the center. When folded, the mounting vertical plate is placed vertically above the mounting disc, and the wedge-shaped blocks on both sides of the mounting vertical plate are rotated from the movable groove to the top of the mounting disc to fix the mounting vertical plate. At the same time, the support block at the bottom of the mounting vertical plate is pressed against the base to fix the mounting disc and the base. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figures 1-9A foldable desk lamp structure includes a base 1 and a mounting vertical plate 2. The mounting vertical plate 2 is mounted on the upper surface of the base 1. The mounting vertical plate 2 is folded and mounted with the base 1. A folding plate 3 is provided above the mounting vertical plate 2. The middle of the folding plate 3 is connected to the mounting vertical plate 2. A main counterweight block 4 is provided at the bottom of the base 1. A movable plate 5 is provided between the main counterweight block 4 and the folding plate 3. A secondary counterweight block 6 is provided in the middle of the folding plate 3. A secondary counterweight unlocking mechanism 7 is provided between the secondary counterweight block 6 and the movable plate 5. The movable plate 5 completes the movement to After the main counterweight 4 moves, the auxiliary counterweight unlocking mechanism 7 releases the fixation of the auxiliary counterweight 6; a light strip mounting rod 8 is provided at the other end of the folding plate 3, and an auxiliary counterweight driving assembly 9 is provided between the light strip mounting rod 8 and the folding plate 3, and the auxiliary counterweight driving assembly 9 includes a fan-shaped support column 91 and a traction rope 92, and the fan-shaped support column 91 is located at the connection between the light strip mounting rod 8 and the folding plate 3, one end of the traction rope 92 is connected to the light strip mounting rod 8, and the other end of the traction rope 92 passes around the fan-shaped support column 91 and is connected to the auxiliary counterweight 6.

[0035] When the folding plate 3 is in use, first stand up from one side of the base 1, the bottom end of the folding plate 3 approaches the mounting vertical plate 2, and the middle of the folding plate 3 rotates with the top of the mounting vertical plate 2, and then the folding plate 3 starts to stand up above the base 1. When the folding plate 3 moves in the direction of the mounting vertical plate 2, the movable plate 5 at the bottom of the folding plate 3 pushes the main counterweight block 4 to move to the other side. At this time, the light strip mounting rod 8 on the top of the folding plate 3 is in the opposite direction of the main counterweight block 4. At the same time, after the movable plate 5 moves toward the main counterweight block 4, the auxiliary unlocking mechanism 7 is used to release the fixation of the auxiliary counterweight block 6; and then the auxiliary driving assembly 9 is used to drive the light strip mounting rod 8 and the folding plate 3 to extend, so that the light strip mounting rod 8 is unfolded and the light strip is facing outward. In this process, the light strip mounting rod 8 extends to one side of the base 1, and the light strip mounting rod 8 and the folding plate The fan-shaped support column 91 at the connection of the stacked plates 3 changes from a round edge contacting the traction rope 92 to a side edge contacting the traction rope 92 of the fan-shaped support column 91, that is, the traction rope 92 reduces the length of the round edge of the fan-shaped support column 91, thereby causing one end of the traction rope 92 to move toward the auxiliary counterweight 6. Since the auxiliary counterweight unlocking mechanism 7 has previously released the auxiliary counterweight 6, under the action of the gravity of the auxiliary counterweight 6, the auxiliary counterweight 6 drops and moves toward the base 1. The dropped auxiliary counterweight 6 cooperates with the main counterweight 4 moving in the opposite direction to move the center of gravity of the table lamp in the opposite direction of the extension of the lamp strip mounting rod 8, thereby avoiding the phenomenon that the center of gravity of the lamp is offset due to the extension of the lamp strip mounting rod 8 during use. That is, through the linkage design of the main counterweight 4 and the auxiliary counterweight 6, dynamic balance of the table lamp is achieved when it is unfolded, avoiding the occurrence of top-heavy.

When the mounting disc 11 is rotated to adjust the lateral angle of the light strip mounting rod 8, the main counterweight 4 is always on both sides of the stretched light strip mounting rod 8 with the mounting vertical plate 2 as the center; when folded, the mounting vertical plate 2 is placed vertically above the mounting disc 11, and the wedge-shaped blocks 21 on both sides of the mounting vertical plate 2 are rotated from the movable groove 12 to the top of the mounting disc 11 to fix the mounting vertical plate 2. At the same time, the support block 22 at the bottom of the mounting vertical plate 2 is in contact with the base 1 to fix the mounting disc 11 and the base 1.

At the same time, the middle part of the folding plate 3 rotates at the top of the mounting vertical plate 2 with the rotating shaft 32 as the axis; when storing, one end of the folding plate 3 moves in the direction away from the mounting vertical plate 2, and at the same time, the wedge-shaped block 21 at the bottom end of the mounting vertical plate 2 rotates into the moving groove 12, so that the mounting vertical plate 2 is released from the fixation, and then can be deflected into the moving groove 12, so that the mounting vertical plate 2 is horizontal and vertical inside the moving groove 12, and the folding plate 3 and the mounting vertical plate 2 are folded and stored in the mounting groove 23 on the other side of the mounting vertical plate 2.

When the folding plate 3 moves toward the mounting vertical plate 2, the unlocking gear 51 under the folding plate 3 cooperates with the teeth on the lower surface of the moving groove 12, causing the unlocking gear 51 to rotate, thereby driving the winding shaft 52 to rotate, winding the unlocking rope 73, so that the other end of the unlocking rope 73 pulls the support platform 72, compressing the support spring 71, thereby causing the bottom of the auxiliary counterweight 6 to lose support, completing the unlocking of the auxiliary counterweight 6.
