Description

Technical Field

[0001] This utility model relates to the field of mobile power technology, and in particular to a power bank. Background Technology

[0002] With the increasing popularity and enhanced functionality of mobile electronic devices, users' demand for portable power supplies is growing. Power banks, as essential devices providing temporary power support, are widely used in daily life. Currently, common power banks on the market typically include a casing, built-in battery cells (battery pack), a circuit board, and a data cable for connecting external devices. Their working principle involves storing electrical energy through the internal battery pack and using control circuitry on the circuit board to provide a stable power supply to external devices.

[0003] In the prior art, the utility model with publication number CN214674486U discloses a power bank with low voltage input and high voltage output, including an upper shell, a lower shell, a circuit board and a battery pack disposed between the shells, and a heat dissipation component on the shell to improve the heat dissipation effect of the battery pack during charging and discharging.

[0004] In practical applications, although the aforementioned heat dissipation structure can effectively cool the battery pack, the lack of effective thermal insulation between the circuit board and the battery pack means that the heat generated by the battery pack during high-power charging and discharging is easily conducted to the circuit board, causing the circuit system temperature to rise. High-temperature environments can not only affect the normal operation of circuit components and reduce overall stability, but also pose risks of short circuits, component aging, and even safety hazards.

[0044] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0045] like Figure 1-4 As shown, the present invention provides a power bank, which includes a shell 1 and a heat insulation plate 2.

[0046] The heat insulation plate 2 is disposed inside the outer shell 1, and has an L-shaped bend 201 at the top and a U-shaped bend 202 at the bottom. The L-shaped bend 201 and the outer shell 1 form a heat insulation cavity 101 for accommodating the circuit board 3. The U-shaped bend 202 and the outer shell 1 form a first accommodating cavity 102 for accommodating the digital display module 4. The bottom surface of the heat insulation plate 2 and the outer shell 1 form a second accommodating cavity 103 for accommodating the battery pack 5.

[0047] In this structure, the heat insulation cavity 101 effectively isolates the circuit board 3 from the battery pack 5, preventing the heat generated by the battery pack 5 from being directly conducted to the circuit board 3. This significantly reduces the operating temperature of the circuit system on the circuit board 3, improving the stability of the circuit system and the safety of the product. Furthermore, this design simplifies the manufacturing process and facilitates assembly.

[0048] In addition, the first receiving cavity 102 is used to install the digital display module 4 and isolate it from the battery pack 5, so as to avoid the heat of the battery pack 5 from interfering with the digital display module 4, which helps to maintain its working stability and improve the intuitiveness and reliability of the user.

[0049] The aforementioned heat insulation plate 2 is made of heat insulation materials with low thermal conductivity and high temperature resistance, such as aerogel composite materials, ceramic fiber boards or heat insulation foam, to effectively block the heat conduction path from the battery pack 5 to the circuit board 3. It has four plate structures: a first plate 21, a second plate 22, a third plate 23 and a fourth plate 24.

[0050] The first plate 21 and the third plate 23 are arranged vertically, and the second plate 22 and the fourth plate 24 are arranged horizontally, and all four are fixedly connected to the rear shell of the outer shell 1; the left end of the second plate 22 is fixedly connected to the bottom end of the first plate 21, the right end is fixedly connected to the top end of the third plate 23, and the bottom end of the third plate 23 is fixedly connected to the left end of the fourth plate 24; the first plate 21 and the second plate 22 form an L-shaped bend 201; the second plate 22, the third plate 23 and the fourth plate 24 form a U-shaped bend 202.

[0051] In this structure, the combination of multiple plates not only enhances the heat insulation effect, but also achieves effective utilization of internal space through a reasonable layout, making the overall structure of the power bank more compact. At the same time, it enhances the overall structural rigidity of the heat insulation plate 2, making it less prone to deformation during long-term use, improving mechanical strength and compressive strength, thereby providing a more stable support environment for internal components and improving the product's durability and safety.

[0052] In addition, a wiring hole 2301 is provided on the right side of the third plate 23 to facilitate wire routing.

[0053] Furthermore, the left end of the second plate 22 extends horizontally to the left to form a reinforcing rib 2201, wherein the reinforcing rib 2201 is fixedly connected to the rear shell of the outer shell 1, so that the heat insulation plate 2 has better structural rigidity and is more resistant to pressure.

[0054] The joints between the first plate 21 and the second plate 22, and between the third plate 23 and the fourth plate 24, are all arc-shaped transitions, which can reduce stress concentration points, prevent material fatigue fracture, and improve the reliability and durability of the heat insulation board 2.

[0055] like Figure 1-4 As shown, the digital display module 4 inside the power bank is installed using a plug-in method. Specifically, a slot 2101 is provided on the right side of the first plate 21, and a socket 105 is provided inside the outer casing 1. The left end of the digital display module 4 is embedded in the slot 2101. A plug-in part 401 is provided on the right end of the digital display module 4, which is embedded in the socket 105. Through plugging, the digital display module 4 can achieve quick and accurate positioning and stable connection during installation, improving assembly efficiency.

[0056] like Figure 1-4 As shown, the circuit board 3 inside the power bank is installed and fixed using a screw and pin structure. Specifically, at least two internally threaded posts 25 are provided on the opposite surfaces of the second plate 22 and the fourth plate 24. At least one locating pin 26 is provided on the side of each internally threaded post 25. The circuit board 3 is provided with a pin hole 301 and a screw mounting hole 302. The locating pin 26 is inserted into the pin hole 301, and a screw is inserted into the screw mounting hole 302 and screwed into the internally threaded post 25, thereby realizing the pin-connected positioning and screw fixing of the circuit board 3 and the internally threaded post 25.

[0057] The above structure enables circuit board 3 to be quickly and accurately positioned and securely connected during installation, thereby improving assembly efficiency.

[0058] The assembly method of the power bank according to this utility model is as follows:

[0059] The battery pack 5 is embedded into the second receiving cavity 103. The circuit board 3 is placed into the heat insulation cavity 101, and the positioning pin 26 is inserted into the pin hole 301. Then, the circuit board 3 is fixed to the internally threaded post 25 inside the heat insulation cavity 101 with screws. The digital display module 4 is placed into the first receiving cavity 102, and its two ends are inserted into the slot 2101 and the socket 105 respectively, completing the installation of the circuit board 3 and the digital display module 4.
