Description
Technical Field
[0001] This utility model relates to a power bank. Background Technology
[0002] With the widespread use of mobile electronic devices, power banks have become an indispensable accessory for users' daily travel. Traditional power banks mainly use wired charging, but with the development of wireless charging technology, portable charging devices that support wireless charging are gradually becoming the mainstream in the market. However, existing wireless power banks still have many limitations:
[0003] 1. Inconvenient charging of multiple devices: Most products can only support wireless charging of a single device, while dual-device power banks are usually large and cannot flexibly adjust the placement angle of the devices, which limits the usage scenarios.
[0004] 2. Impractical support structure: Although some products are equipped with a phone stand function, the support frame is mostly external or fixed, which cannot be stored or takes up extra space and is easily damaged when carried.
[0005] 3. Insufficient heat dissipation: High-power wireless charging is prone to heat accumulation. Existing products have a single heat dissipation design (such as relying solely on openings), which leads to decreased charging efficiency and even safety hazards.
[0006] To address the aforementioned issues, there is an urgent need for a power bank that integrates dual wireless charging modules, a retractable support structure, an efficient heat dissipation solution, and multi-angle adjustment capabilities to enhance user experience and adapt to diverse usage scenarios.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.
[0032] A preferred embodiment of this utility model is a power bank, such as... Figure 1-3As shown, the device includes a first charging dock 11 and a second charging dock 12. The first charging dock 11 rotates on the upper side of the second charging dock 12 via a first rotation damping assembly 13. Users can adjust the relative positions of the two charging docks as needed to flexibly adapt to different charging requirements and usage scenarios. For example, the two charging docks can be placed side by side or staggered to facilitate simultaneous charging of devices of different sizes. In this embodiment, the first rotation damping assembly 13 is a damper structure or a damping hinge structure in the prior art, or includes a rotating shaft and a layer of silicone wrapped around the rotating shaft to increase rotational resistance. The first charging dock 11 can be folded and placed with the second charging dock via the first rotation damping assembly 13, making it compact and easy to store. The first charging dock 11 can also be unfolded into place on the second charging dock via the first rotation damping assembly 13, facilitating simultaneous charging of multiple devices.
[0033] Furthermore, the upper surface of the first charging stand 11 is provided with a first charging position 111 for placing a mobile phone. Inside the first charging stand 11, below the first charging position 111, is a first wireless charging module (not shown in the figure) for wirelessly charging mobile phones. The upper surface of the second charging stand 12 is provided with a second charging position 121. Inside the second charging stand 12, below the second charging position 121, is a second wireless charging module (not shown in the figure) for wirelessly charging electronic watches, Bluetooth earphone cases, or other electronic devices with wireless charging function. It is worth noting that both the first wireless charging module and the second wireless charging module are existing wireless charging structures, enabling simultaneous charging of multiple devices, improving charging efficiency, and making it convenient for users to charge mobile phones and other small devices at the same time.
[0034] Furthermore, a U-shaped support frame 14 is provided on the outer side of the frame 122 of the second charging base 12. The U-shaped support frame 14 can provide stable support for the entire power bank, preventing it from tipping over or shaking during use. The support frame 14 is arranged around one end of the frame 122. The outer surface of the frame 122 is provided with a receiving groove 123 along its length to accommodate the support frame 14. When the support frame is not needed, it can be stored in the receiving groove to keep the power bank neat and compact. The support frame 14 rotates on the underside of the second charging base 12 via a second rotation damping assembly (not shown in the figure), allowing the user to adjust the relative position of the two charging positions as needed, optimizing space utilization, and also allowing the user to easily adjust the support angle to adjust the height of the power bank, adapting to different usage scenarios and habits. In this embodiment, the second rotation damping assembly is a rotating shaft connected to the frame and a damping plate sleeved on the rotating shaft, as in the prior art.
[0035] Furthermore, the lower edge of the opening of the receiving slot 123 is flush with the lower surface of the second charging base 12, allowing the support frame to rotate smoothly outward. The two ends of the support frame 14 extend into the two ends of the receiving slot 123 and are rotatably connected to the frame 122 through the second rotation damping assembly, resulting in a compact structure and small size. The frame 122 is also provided with a limiting part 124 along the length of the receiving slot 123 to prevent the support frame 14 from rotating onto the upper surface of the second charging base 12. This ensures that the support frame will not exceed the set range when rotating, preventing the support frame from rotating onto the upper surface of the charging base and avoiding possible damage or inconvenience in use. By limiting the rotation range of the support frame, the safety during use is increased, preventing the equipment from tipping over or being damaged due to excessive rotation of the support frame.
[0036] Furthermore, the limiting part 124 has a groove 125 on the side surface facing away from the upper surface of the second charging base 12, which communicates with the receiving groove 123, so that there is a gap between the support frame 14 and the limiting part 124, making it easy for the user to pull the support frame 14 out of the receiving groove 123.
[0037] Furthermore, the support frame 14 is a flat, elongated structure. The flat, elongated structure occupies less space when stored and can fit closely to the frame 122 of the second charging base 12, making the entire power bank more compact when stored, and easier to carry and store. Moreover, the support frame 14 can provide sufficient support area when unfolded to ensure the stability of the second charging base 12 when placed.
[0038] Furthermore, the first charging base 11 also includes a magnetic module (not shown) that attracts the phone to the first charging position 111. This magnetic module is existing technology. It guides the phone to quickly align with the wireless charging coil, eliminating the need for precise positioning and improving charging efficiency. The magnetic force of the module prevents the phone from sliding or falling due to external forces (such as collisions or friction) during charging, ensuring continuous and safe charging. Stable attraction also ensures good coupling between the phone and the wireless charging coil, further improving wireless charging efficiency.
[0039] Furthermore, the lower surface of the second charging base 12 is provided with a partition 15; the partition 15 includes a substrate 151 parallel to the lower surface of the second charging base 12, and a sidewall 152 extending from the outer edge of the substrate 151 toward and connecting to the lower surface of the second charging base 12; a heat dissipation channel is provided between the substrate 151 and the partition 15; the heat dissipation channel formed between the substrate 151 and the sidewall 152 can provide an effective heat dissipation path for the electronic components inside the second charging base 12. Air can circulate through these channels, carrying away heat, thereby reducing the operating temperature of the charging base and improving its stability and service life; the two ends of the substrate 151 are respectively provided with a first opening 153 and a second opening 154 communicating with the heat dissipation channel. The first opening 153 and the second opening 154 are both connected to the heat dissipation channel, which can further promote air convection and enhance the heat dissipation effect. Especially during the charging process, electronic components will generate a lot of heat, and a good heat dissipation design can prevent overheating and ensure charging efficiency and safety.
[0040] Furthermore, the first opening 153 is in the shape of a straight line, extending radially from the center of one end of the substrate 151 to both sides; the second opening 154 is U-shaped, extending axially from the center of the other end of the substrate 151 towards its corresponding first opening 153. The combined design of the first and second openings allows for air convection, improving heat dissipation efficiency. Hot air is exhausted through the openings, while cool air enters from the other side, forming a natural air circulation. The size of the first opening is smaller than that of the second opening, resulting in a faster heat dissipation flow rate.
[0041] Furthermore, when the support frame 14 is stored in the receiving slot 123, the outer surface of the support frame 14 is flush with or lower than the outer surface of the frame 122, making the power bank look neater and smoother when stored, without any protruding parts, thus improving the overall aesthetics and visual effect.
[0042] Optionally, an anti-slip pad 126 is fixedly provided on the second charging position 121; the center of the anti-slip pad 126 is concave inward, which can increase the friction between the pad and the object (such as a mobile phone, earphones, etc.) and effectively prevent the object from sliding or falling due to accidental collision or vibration during charging.
[0043] Optionally, the rotation angle between the first charging base 11 and the second charging base 12 is less than 180°; the rotation angle between the second charging base 12 and the support frame 14 is not greater than 90°.
[0044] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
