Description

Technical Field

[0001] This utility model relates to the field of desk lamp technology, and in particular to a folding eye-protecting desk lamp with a charging interface. Background Technology

[0002] Eye-protecting desk lamps can reduce eye fatigue, visual stimulation, and potential damage during prolonged use. They typically have a frosted lampshade installed on the LED light panel, which allows the light emitted by the LED beads to be reflected multiple times before being emitted, reducing the proportion of "direct light" and making the light softer, thus meeting the basic requirements for eye protection.

[0003] In particular, the folding eye-protection desk lamp adopts a rotating and foldable structure, which makes it easy to adjust the height and tilt angle of the LED light panel to meet the different needs of users. Moreover, the overall space occupied by the folded desk lamp is reduced, making it easy to store.

[0004] However, in actual use, the frosted lampshade is fragile and the USB charging port is easily loosened by external force. After the lamp is folded and stored, neither the lampshade nor the charging port is effectively protected, which increases the chance of damage to both and significantly reduces the lifespan of the lamp. Therefore, we propose a foldable eye-protection desk lamp with a charging port that can effectively protect the folded lamp. Utility Model Content

[0005] The purpose of this invention is to address the problem in the background art that the frosted lampshade and USB charging port are at increased risk of damage when subjected to external forces, and to propose a foldable eye-protection desk lamp with a charging port that can effectively protect the folded desk lamp.

[0006] The technical solution of this utility model: a folding eye-protecting desk lamp with a charging interface, including a lamp base, and further comprising:

[0007] A storage slot is provided on the top of the lamp holder. A support frame is rotatably mounted on the two opposite inner sidewalls of the storage slot. An LED light panel is rotatably mounted on the support frame. The storage slot is used to store the folded support frame and LED light panel.

[0008] An interface protection slot is provided at one end of the lamp holder, and a USB charging interface is fixedly installed on the lamp holder and inside the interface protection slot. The interface protection slot is used to protect the USB charging interface.

[0009] Optionally, positioning blocks are fixedly installed on the two outer side walls near the bottom of the support frame. The positioning blocks are fixedly installed on the inner side wall of the storage slot. The bottom of the support frame is rotatably connected to the matching positioning blocks through a connecting shaft. The LED light panel is rotatably connected to the inner side wall of the support frame through a connecting shaft.

Wiring channels are provided inside the lamp holder and the support frame, and the wiring channels are interconnected with the matching wire holes.

[0011] Optionally, the lamp holder has two hidden grooves inside, one end of each hidden groove is connected to the interface protection groove, and a protective plate is movably installed in each hidden groove. The protective plate is located on one side of the USB charging interface.

[0012] Optionally, a sponge pad is fixedly installed at the bottom of the storage slot, and the top of the sponge pad has two symmetrically arranged protrusions. Several heat dissipation holes are cut on both outer side walls of the LED light panel, and a frosted lampshade is fixedly installed at the bottom of the LED light panel.

[0013] Optionally, a bottom cover is fixedly installed at the bottom of the lamp holder, and a battery, an AC-DC rectifier module, a charging management module, and a circuit board are fixedly installed on the top of the bottom cover and inside the lamp holder.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0029] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the folding eye-protecting desk lamp with charging interface proposed in this utility model includes a lamp base 1. The top of the lamp base 1 is carved with a storage groove 3. A support frame 5 is rotatably installed on the two opposing inner side walls of the storage groove 3, which facilitates the rotation and adjustment of the support frame 5. An LED light panel 6 is rotatably installed on the support frame 5, which also facilitates the rotation and adjustment of the LED light panel 6. By supporting the LED light panel 6 with the support frame 5, the height and tilt angle of the LED light panel 6 can be adjusted according to usage needs, improving its applicability. When the LED light panel 6 and the support frame 5 are both folded and stored inside the storage groove 3, they can protect the lampshade structure. One end of the lamp base 1 is carved with an interface protection groove 8. A USB charging interface 7 is fixedly installed on the lamp base 1 and inside the interface protection groove 8. The USB charging interface 7 is designed to be hidden, which can prevent external force from touching the USB charging interface 7 and avoid loosening, effectively improving the protection effect of the charging interface.

[0030] like Figures 1-4As shown, in order to facilitate the rotation and adjustment of the desk lamp, positioning blocks 51 are fixedly installed on the two outer side walls near the bottom of the support frame 5. The positioning blocks 51 are fixed on the inner side wall of the storage slot 3. The bottom of the support frame 5 is rotatably connected to the matching positioning blocks 51 through the connecting shaft, which facilitates the rotation and adjustment of the support frame 5. The outer side wall of the LED light panel 6 is rotatably connected to the inner side wall of the support frame 5 through the connecting shaft, which facilitates the rotation and adjustment of the LED light panel 6.

[0031] Furthermore, in order to improve the stability of the support frame 5 and LED light panel 6 after adjustment, damping plates are installed at the connection between the connecting shaft and the positioning block 51 and the inner wall of the support frame 5. After the support frame 5 and LED light panel 6 are rotated and adjusted, the damping plates increase the frictional resistance on the outer surface of the connecting shaft, reduce the force exerted on the connecting shaft by the weight of the support frame 5 and LED light panel 6, and effectively improve the stability of the two after adjustment.

[0032] Secondly, wiring channels are drilled inside both the lamp holder 1 and the support frame 5, and wire holes 52 are drilled on the inner walls of the positioning block 51 and the support frame 5. The cable led out from the lamp holder 1 first passes through the wiring channel drilled on the lamp holder 1, then through the wire hole 52 on the positioning block 51, and then into the wiring channel drilled on the support frame 5. Finally, it passes out through the wire hole 52 drilled on the inner wall of the support frame 5, and can be electrically connected to the LED light board 6 (a through hole structure is reserved on the connecting shaft to facilitate wire threading), ensuring that the battery 11 inside the lamp holder 1 can supply power to the LED light board 6, so that the LED beads installed on the LED light board 6 can emit light.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in order to effectively protect the folded frosted lampshade 61, a sponge pad 4 is fixedly installed at the bottom of the storage slot 3. When the LED light panel 6 is stored inside the storage slot 3, the frosted lampshade 61 is pressed onto the sponge pad 4. The sponge pad 4 covers and protects the frosted lampshade 61 to prevent it from being damaged by external forces.

[0034] Furthermore, to enhance the protection of the USB charging port 7, two hidden grooves 81 are carved inside the lamp holder 1. The openings of the hidden grooves 81 are connected to the interface protection groove 8. A protective plate 82 is movably installed inside the hidden grooves 81. When the lamp needs to be charged, the protective plate 82 is pushed into the hidden groove 81, which opens the opening of the interface protection groove 8, making it easy to plug the charging cable into the USB charging port 7. After charging is complete, the charging cable is unplugged and the two protective plates 82 are pulled. When the two protective plates 82 are closed together, a folded protective structure is formed on one side of the USB charging port 7, preventing dust from entering and preventing the USB charging port 7 from loosening due to external forces, thus effectively improving the protection of the USB charging port 7.

[0035] Secondly, in order to reduce the chance of dust entering the LED light panel 6, several heat dissipation holes 62 are drilled on both outer side walls of the LED light panel 6, which helps the heat inside the light panel to be discharged outward and improves the heat dissipation effect of the desk lamp. After the LED light panel 6 is stored in the storage slot 3, the protrusions 41 set on the top of the sponge pad 4 cover one side of the LED light panel 6. By covering and blocking the heat dissipation holes 62 with the protrusions 41, the chance of dust entering the LED light panel 6 can be reduced, and the dustproof effect when it is stored can be improved.

[0036] like Figure 4 As shown, to ensure the safety of the desk lamp charging, a bottom cover 2 is fixedly installed at the bottom of the lamp holder 1. A battery 11, an AC-DC rectifier module 12, a charging management module 13, and a circuit board 14 are fixedly installed on the top of the bottom cover 2. All of these electrical components are installed inside the lamp holder 1. The bottom cover 2 can be removed by unscrewing the screws threaded onto the lamp holder 1, facilitating the repair of some of the electrical components inside the desk lamp. A USB charging port 7 is electrically connected to the AC-DC rectifier module 12 via a cable. The AC-DC rectifier module 12 converts household 220V AC power into stable low-voltage DC power (commonly 5V, 9V, or 12V) acceptable to the subsequent circuitry of the desk lamp (such as the charging management module 13). The AC-DC rectifier module 12 is also electrically connected to the charging management module 13 via a cable. The charging management module 13 converts the low-voltage DC power output from the AC-DC rectifier module 12 (or USB power) into a stable low-voltage DC power output from the AC-DC rectifier module 12. The input 5V is converted into current / voltage that conforms to the charging characteristics of the battery, and overcharge, over-discharge and short circuit protection are implemented at the same time. The charging management module 13 is electrically connected to the battery 11 through a cable, the battery 11 is electrically connected to the circuit board 14 through a cable, and the circuit board 14 is electrically connected to the LED light board 6 through a cable, which can provide stable power supply to the LED light board 6.

[0037] Secondly, the aforementioned AC-DC rectifier module 12 consists of a high-frequency switching transformer, a switching power supply IC, etc., and the charging management module 13 consists of a charging management IC, a current sampling resistor, etc., all of which are existing technologies and will not be described in detail here.

[0038] In this embodiment, when the desk lamp is in use, the LED lamp panel 6 is stably supported by the support frame 5. When the support frame 5 is rotated and adjusted, the tilt angle between the support frame 5 and the lamp holder 1 can be changed, making it convenient to adjust the height of the LED lamp panel 6. When the LED lamp panel 6 is rotated and adjusted, the tilt angle between the LED lamp panel 6 and the support frame 5 can be changed, making it convenient to adjust the tilt angle of the LED lamp panel 6, thus changing the illumination angle. The desk lamp can be flexibly adjusted according to usage needs. The light emitted by the LED beads is reflected by the frosted lampshade 61 to ensure that the desk lamp emits soft light to meet eye protection requirements.

[0039] When the desk lamp is finished using and folded for storage, the support frame 5 and LED light panel 6 are rotated and adjusted to ensure that both are stored inside the storage slot 3, thereby reducing the overall space occupied by the desk lamp and facilitating its storage. At this time, the frosted lampshade 61 is pressed onto the sponge pad 4, which protects the frosted lampshade 61 from damage caused by external forces. When the desk lamp is not charging, the two protective plates 82 are pulled together. When the two protective plates 82 are joined together, they form a shield on one side of the USB charging port 7. This not only prevents dust from entering the USB charging port 7 but also reduces the chance of damage caused by external forces. Effective protection of the vulnerable parts of the desk lamp reduces the chance of damage and effectively improves its service life.

[0040] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
