Description

Technical Field

[0001] This application relates to the technical field of portable power banks, and more specifically, to a portable power bank with a built-in light. Background Technology

[0002] With the widespread use of portable electronic devices, power banks have become an indispensable energy storage and power supply device in people's daily lives. To meet users' needs in low-light or nighttime environments, power bank products with integrated lighting functions have emerged in the current technology. These products typically have the lighting lamp (such as LED beads or small light panels) directly fixed to the surface of the power bank casing, and the lighting function is achieved through simple on / off control.

[0003] However, existing portable power banks with lighting features have significant limitations: First, because the lamp and the power bank are rigidly connected, the illumination angle cannot be flexibly adjusted according to the usage scenario. For example, when a user needs to project light to different heights or directions, the illumination direction must be adjusted by changing the overall position of the power bank, which is extremely inconvenient. Second, the fixed installation limits the illumination range of the lamp, making it impossible to expand or focus the light coverage area through height adjustment, which is particularly impractical in scenarios requiring multi-angle lighting, such as outdoor emergencies and nighttime operations. Although some improvements attempt to address these issues by using detachable external lighting accessories, such designs suffer from drawbacks such as easy loss of accessories, additional usage steps, and insufficient power supply stability. Therefore, how to achieve flexible adjustment of the height and angle of the lighting component while maintaining the portability of the power bank, ensuring structural reliability and ease of operation, and taking into account the consistency and aesthetics of the power bank's appearance, remains a pressing technical problem to be solved in this field. Utility Model Content

[0004] To address the problem in related technologies where the lighting is directly fixed to the surface of the power bank housing, resulting in a limited illumination range, this application provides a power bank with an integrated lighting unit.

[0005] A portable power bank with a built-in light includes a power housing, inside which a battery assembly is installed. The power housing has a connector assembly for connecting to an external power source and an electrical device. The connector assembly is connected to a main functional circuit board, which is electrically connected to the battery assembly. A vertical telescopic rod is fixed to the bottom of the power housing, extending through the top of the power housing. A damping joint is provided at the top of the telescopic rod, and a light housing is hinged to the damping joint. A light source is disposed inside the light housing.

[0006] By adopting the above technical solution and combining the vertical telescopic rod with the damping joint, a dual height and angle adjustment function for a lighting lamp has been achieved for the first time in a portable power bank. Users can independently operate the telescopic rod to change the height of the lighting lamp, such as stretching it to expand the illumination range or compressing it to focus the light. At the same time, the angle of the lighting lamp can be adjusted by the hinge of the damping joint, and the damping joint has the characteristic of resistance retention to flexibly fix it at the adjusted angle. It can meet the lighting needs of different scenarios without the need for the portable power bank itself, significantly improving its practicality for outdoor emergency, night work and other scenarios.

[0007] Preferably, the top of the power supply housing is recessed inward with a groove, and the contour and size of the groove match the outer periphery contour and size of the lamp housing.

[0008] By adopting the above technical solution, the lamp housing is embedded in the groove, which helps to eliminate the problem of increased volume caused by the traditional protruding lamp body, making it easy to carry and avoiding damage from bumps; the groove fits tightly with the lamp housing, reducing gaps at the interface and reducing the risk of dust and moisture intrusion during outdoor use.

[0009] Preferably, a handle is provided on the top surface of the lamp housing.

[0010] By adopting the above technical solution, the grip provides a fulcrum for force application, making it easy for users to hold, extend, retract, or adjust the angle of the light source, which is more practical and convenient.

[0011] Preferably, the battery assembly includes a BMS circuit board and multiple battery cells, which are connected in series or parallel through the BMS circuit board.

[0012] By adopting the above technical solutions, multiple battery modules can be connected in series or in parallel to increase the total capacity and extend the lighting and charging time; the BMS circuit board realizes overcharge or over-discharge protection and balanced charging and discharging, avoiding the risk of thermal runaway that may be caused by multiple cells connected in series or in parallel.

[0013] Preferably, the connector assembly includes a main charging connector, a solar charging connector, a discharging connector, a display screen, and a solar charging control circuit board. The number of the main charging connector and the discharging connector is at least one. The main charging connector, the discharging connector, and the display screen are all embedded in the side wall of the power supply housing and are all welded to the main functional circuit board. The solar charging connector is also embedded in the side wall of the power supply housing and is welded to the solar charging control circuit board. The solar charging control circuit board is connected to the main functional circuit board via wires.

[0014] By adopting the above technical solutions, multiple charging and discharging connectors expand device compatibility, allowing multiple devices to be powered simultaneously; using solar charging connectors allows the power bank to be charged using solar energy, increasing its outdoor battery life; and displaying data such as power level and charging power on the screen makes it easier for users to understand the power bank's usage status, which is quite practical.

[0015] Preferably, the light source includes an LED light board and a spring cable. The LED light board is fixed inside the lamp housing. One end of the spring cable is connected to the LED light board, and the other end of the spring cable passes through the lamp housing and the power supply housing and is connected to the main functional circuit board.

[0016] By adopting the above technical solution, the spring cable can be stretched or compressed along with the telescopic rod, avoiding internal breakage caused by repeated bending of rigid wires.

[0017] Preferably, the telescopic rod includes at least three rod sections, each of which is a hollow tubular shape, and each rod section is connected sequentially according to its diameter. Adjacent rod sections are tightened by friction. The rod section with the largest diameter is connected and fixed to the bottom of the power supply housing, and the damping joint is located at the top of the rod section with the smallest diameter.

[0018] By adopting the above technical solution, at least three sections of the rod can achieve a greater height adjustment range for the telescopic rod. At the same time, the friction tensioning structure provides segmented damping, which can not only be operated with one hand for telescopic extension and retraction, but also prevent automatic slippage under the action of gravity.

[0019] Preferably, a connecting ring is provided on the bottom surface of the power supply housing. The inner diameter of the connecting ring matches the diameter of the telescopic rod with its maximum diameter. The bottom end of the telescopic rod with its maximum diameter is inserted into the inner hole of the connecting ring, and there is a gap between its bottom end and the bottom surface of the power supply housing. The telescopic rod with its maximum diameter is locked and fixed to the connecting ring by bolts. The connecting ring has a notch at the lower end of the telescopic rod with its maximum diameter. The damping joint has a through hole that connects to the interior of the telescopic rod. The spring cable passes through the through hole of the damping joint into the interior of the telescopic rod and exits from the bottom end of the telescopic rod with its maximum diameter. The spring cable also exits through the notch of the connecting ring and connects to the main functional circuit board.

[0020] By adopting the above technical solution, the spring cable is hidden inside the telescopic rod, which makes the overall appearance of the power bank simple and the visual effect better.

[0021] Preferably, the power supply housing is hinged with a handle.

[0022] By adopting the above technical solution, the handle makes it convenient for users to hold and carry the power bank.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Through the combined design of a vertical telescopic rod and a damping joint, the lighting component achieves dual height and angle adjustment for the first time in a portable power bank. Users can independently operate the telescopic rod to change the height of the light, such as stretching it to expand the illumination range or compressing it to focus the light. At the same time, the damping joint allows for adjustable angle adjustment of the light, and its resistance-holding characteristic allows it to be flexibly fixed at the adjusted angle. This eliminates the need for the power bank itself to meet the lighting needs of different scenarios, significantly improving its practicality for outdoor emergencies, nighttime operations, and other scenarios.

[0025] 2. The top of the power supply housing has an inward recessed groove, into which the lamp housing is embedded. This helps to eliminate the increased size caused by the traditional protruding lamp body, making it easier to carry and preventing damage from bumps. The groove fits tightly with the lamp housing, reducing gaps at the interface and lowering the risk of dust and moisture intrusion during outdoor use.

[0026] 3. The light source includes an LED light board and a spring cable. The spring cable can be stretched / compressed with the telescopic rod to avoid internal breakage caused by repeated bending of rigid wires. The telescopic rod includes at least three rod sections, each of which is a hollow tubular shape. The spring cable is hidden inside the telescopic rod, which makes the overall appearance of the power bank simple and visually appealing. Attached Figure Description

[0037] Reference Figure 2 and Figure 3Furthermore, the telescopic rod 5 includes at least three rod sections, each of which is a hollow tubular shape. The rod sections are sequentially connected according to their diameter, and adjacent sections are tightened by friction. The bottom end of the rod with the largest diameter is inserted into the inner hole of the connecting ring 1221, with a gap between its bottom end and the bottom panel 122. The rod with the largest diameter of the telescopic rod 5 is bolted to the connecting ring 1221, and the height of the rod is less than the distance between the top panel 112 and the bottom panel 122. The connecting ring 1221 has a notch at the lower end of the rod with the largest diameter of the telescopic rod 5. The damping joint 6 is located at the top of the rod with the smallest diameter. The light source includes an LED light panel 71 (not shown in the figure) and a spring cable 72 (not shown in the figure). The LED light panel 71 is fixed inside the lamp housing 7. One end of the spring cable 72 is connected to the LED light panel 71, and the lamp housing 7 has an opening. The damping joint 6 has a through hole communicating with the interior of the telescopic rod 5. The other end of the spring cable 72 passes through the opening, exits the lamp housing 7, and passes through the through hole. The telescopic rod 5 is inserted into the telescopic rod 5 and passes through the notch of the connecting ring 1221 to connect to the main functional circuit board 4. In the above structure, the telescopic rod 5 with at least three sections has a larger height adjustment range. At the same time, the rod provides segmented damping through friction tension, which can be operated with one hand for telescopic extension and extension and can prevent automatic slippage under gravity. The spring cable 72 is used as the connecting wire between the light source and the battery cell 21. The spring cable 72 can be stretched or compressed with the telescopic rod 5 to avoid internal breakage caused by repeated bending of rigid wires. The spring cable 72 is hidden by passing through the telescopic rod 5, which makes the overall appearance of the power bank simple and visually better. The height of the rod is less than the distance between the top panel 112 and the bottom panel 122, which makes it easy for the lamp housing 7 to be embedded in the groove 113 of the top panel 112. This helps to eliminate the problem of increased volume caused by the traditional protruding lamp body, making it easy to carry and avoiding damage from bumps. The groove 113 fits tightly with the lamp housing 7, reducing gaps at the interface and reducing the risk of dust and moisture intrusion during outdoor use.

[0038] Reference Figure 3 Furthermore, the main functional circuit board 4 also integrates a switch 41, which is embedded in the side wall of the intermediate cylinder 13. The switch 41 controls the current flow to the spring cable 72, thereby turning the lighting lamp on or off.

The inner hole of the outer ring 61 is perpendicular to the telescopic direction of the telescopic rod 5. The inner ring 62 is made of a material with damping characteristics, preferably rubber. The lamp housing 7 has a U-shaped frame 73 formed at the bottom end. Circular protrusions 731 are protruding on both sides of the U-shaped frame 73. The two circular protrusions 731 are inserted into the inner ring 62 through the two ends of the inner ring 62, so as to realize the hinge connection between the damping joint 6 and the lamp housing 7. The outer ring 61 and the inner ring 62 are provided with a through hole in the middle of the axial direction. The through hole is provided through the outer ring 61 and the inner ring 62 in the radial direction.

[0040] Reference Figure 1 and Figure 2 Furthermore, a handle 74 is provided on the top surface of the lamp housing 7. The handle 74 provides a fulcrum for applying force, making it convenient for users to hold, extend, retract, or adjust the angle of the light source, which is more practical and convenient.

[0041] Reference Figure 1 and Figure 2 Furthermore, a handle 114 is hinged to the top cover 11. The handle 114 is formed by bending a metal rod into a semi-circular arc shape, and the two ends of the semi-circular metal rod are bent into opposing horizontal sections. Insertion holes are provided on opposite sides of the first ring body 111. The inner diameter of the insertion holes matches the diameter of the metal rod. The handle 114 is hinged to the top cover 11 by inserting the horizontal sections at both ends of the metal rod into the two insertion holes respectively. The handle 114 makes it convenient for users to hold and carry the power bank.
