Description

Technical Field

[0001] This utility model relates to the field of floor lamp technology, and in particular to a floor lamp that resembles a sunflower. Background Technology

[0002] Currently, sunflower-inspired floor lamps allow users to adjust the lampshade height as needed or set different time periods for different height adjustments. For example, users can adjust the lampshade height via remote control or intelligently set the lampshade to be at different heights at different times. The lampshade's orientation angle can also be adjusted to mimic a sunflower.

[0003] These sunflower-inspired floor lamps have issues with the electrical connection wires during height adjustment. These issues can cause the wires to be pulled, bent, or scraped repeatedly, which can easily damage the wire insulation. Furthermore, they require complex wiring designs, especially as the adjustable height increases. The more complex the wiring design needs to be, the more difficult it is to minimize the aforementioned issues of wire pulling, bending, or scraping. These issues need to be improved.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 A sunflower-shaped floor lamp includes a base 1, on which a lifting guide rod 2, a drive motor 3, and a lead screw 4 driven by the drive motor are mounted. The lead screw 4 is positioned vertically.

[0017] A lifting guide rail 5 is provided on the lifting guide rod 2, and a lifting head 6 is slidably mounted on the lifting guide rail 5. A nut 7 that cooperates with a lead screw is connected to the lifting head 6. The drive motor 3 drives the lead screw 4 to rotate. Under the threaded engagement of the lead screw 4 and the nut 7, and guided by the lifting guide rail 5 and the lifting head 6, the lifting head 6 can be driven to rise / fall on the lifting guide rail 5.

[0018] The base 1 is also equipped with an electrical control module 8 and a conductive plate 9, which is designed with vertical length. The conductive plate 9 is equipped with multiple non-conductive upper and lower electrical connection strips 10, and the lower ends of the upper and lower electrical connection strips 10 are electrically connected to the corresponding pins of the electrical control module.

[0019] The lifting head 6 is provided with a light source assembly 11, which includes a light-emitting element 12 and a lifting head conductive plate 13 disposed on the lifting head; the lifting head conductive plate 13 is provided with a plurality of sliding electrical connection contact points 14 that slide in contact with a plurality of upper and lower electrical connection contact strips.

[0020] During lifting and adjustment, the cable wiring connection in the lifting area can be removed through the sliding electrical connection structure between the conductive plate 9 and the lifting head conductive plate 13. During lifting and adjustment, there will be no pulling, repeated curves or scraping of the cable in the lifting area. During the lifting and adjustment process, the electrical control module can supply power to the lifting head conductive plate of the light source component through the conductive plate, so that the light-emitting component of the light source component can be powered to work and emit light.

[0021] In some embodiments, when the electronic control module is also used for other controls besides powering on the light source component, such as controlling its color change, the multiple upper and lower electrical connection contact strips are at least three upper and lower electrical connection contact strips. The first upper and lower electrical connection contact strip is configured as a positive electrical connection contact strip 10a, the second upper and lower electrical connection contact strip is configured as a negative electrical connection contact strip 10b, and the third upper and lower electrical connection contact strip is configured as a control signal electrical connection contact strip 10c, so that the electronic control module can output corresponding control signals to the light source component.

[0022] In some embodiments, the lifting head 6 is provided with a lampshade box 15, and the lampshade box 15 has a light-transmitting protective cover 16.

[0024] The lampshade box 15 is movably connected to the lifting head 6, allowing the orientation of the lampshade box 15 to be adjusted on the lifting head 6. Correspondingly, adjusting the orientation of the lampshade box adjusts the illumination direction of the lamp panel connected to the lampshade box.

[0025] In some embodiments, an adjusting ball head 18 is connected to the lifting head 6, and an adjusting ball seat 19 that cooperates with the adjusting ball head is connected to the lampshade box 15. The adjusting ball seat 19 is sleeved on the adjusting ball head 18, so that the lampshade box and the lifting head are movably connected.

[0026] In some embodiments, the overall shape of the lampshade box can be set to resemble a sunflower, so that the device, apart from the height adjustment and head orientation changes that mimic a sunflower, is more similar to a sunflower in overall shape.

[0027] In some embodiments, both the base 1 and the lifting guide rod 2 have an installation space inside, and the installation space inside the base is connected to the installation space inside the lifting guide rod. The lifting guide rod has a lifting clearance hole 20 on its outer side.

[0028] The drive motor 3 is installed inside the base 1, the conductive plate 9 is installed inside the lifting guide rod 2, and the lead screw 4 extends from the base and passes through the lifting guide rod.

The lifting head conductive plate 13 can be correspondingly installed on this part of the structure so that the sliding electrical connection contact point 14 on the lifting head conductive plate 13 can contact the corresponding upper and lower electrical connection contact strips on the conductive plate 9.

[0030] In some embodiments, a speed change assembly 21 is also provided in the base 1, which causes the rotational speed between the drive motor 3 and the lead screw 4 to change. For example, the speed change assembly is a reduction gear assembly, the input gear of which is connected to the rotary output shaft of the drive motor, and the output gear of which is connected to the lead screw.

[0031] In some embodiments, the upper and lower electrical connection contact strips 10 are, for example, contact strips made of conductive metal, such as copper strips.

[0032] Sliding electrical contact points are, for example, contacts made of conductive metal.

[0033] In some embodiments, the sliding electrical contact 14 is configured as a spring, elastically abutting against the upper and lower electrical contact bars, and abutting against the sides of the upper and lower electrical contact bars. During lifting and lowering, the sliding electrical contact 14 makes more stable contact with the corresponding upper and lower electrical contact bars.

[0034] In some embodiments, the electronic control module 8 includes a power supply module to supply power to the light-emitting element 12 via the conductive plate 9 and the lifting head conductive plate 13. Preferably, the electronic control module further includes a control module to control the light-emitting element via the conductive plate and the lifting head conductive plate.

[0035] In some embodiments, the control module can also be used to control the drive motor 3 to operate, so as to control the corresponding upward / downward drive.

[0036] In some embodiments, the light source assembly further includes a light source end control chip, which receives control signals transmitted by the control module through a conductive plate and a lifting head conductive plate to control the light-emitting element accordingly.
