Description

Technical Field

[0001] This utility model relates to the field of power bank technology, and more specifically to a power bank with a protected charging port. Background Technology

[0002] A power bank is a portable mobile power supply device primarily used to replenish the power of digital products such as mobile phones, tablets, and smartwatches when no external power source is available, such as outdoors, while traveling, or during power outages, thus solving the problem of device battery life. Existing power banks typically consist of battery cells, circuit boards, a casing, and a charging interface. The battery cells are the core components that store electrical energy; common types include lithium-ion cells, and their capacity directly determines the number of times the power bank can charge a device. The circuit board manages the charging and discharging process, providing overcharge protection, over-discharge protection, and short-circuit protection to ensure safe use. The casing protects the internal components and is made of various materials, such as plastic and metal, with designs increasingly emphasizing portability and aesthetics.

[0003] For example, the power bank with prior art publication number CN217216033U allows digital devices to be charged anytime, anywhere. A circular stop slightly higher than the power bank's thickness prevents it from entering the rental cabinet from that side, ensuring customers return the power bank in the correct direction and guaranteeing its proper use. An arrow on the power bank's front further guides customers to return it in the correct direction, ensuring both the power bank's functionality and the safety of the rental cabinet. The power bank also contains a Bluetooth chip that communicates with the identification device inside the rental cabinet, preventing other types of power banks from being inserted and ensuring the cabinet's security.

[0004] However, the existing technology described above still has the following problems in use: Although traditional power banks have built-in charging ports, dust and impurities can easily clog the charging ports during transport, leading to poor contact between the charging port and the charging head, affecting charging speed, and in severe cases, affecting charging safety. Based on this, this utility model provides a power bank with a protected charging port. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a power bank with charging port protection. By placing two lithium-ion battery cells through a partition, the charging capacity is increased. The two charging ports and one charging cable can simultaneously charge three devices and support the function of charging and discharging at the same time, effectively meeting the battery life needs of multiple devices when traveling. In addition, the rubber plug can prevent dust and impurities from clogging the charging port and affecting subsequent use, and can also prevent the charging port from being damaged by collisions with objects, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power bank with charging port protection, comprising an upper shell and a lower shell. The lower shell has two charging ports and a charging cable embedded in its side wall. An insertion port is opened on one side of the lower shell, and the connector of the charging cable is inserted into the insertion port. Rubber plugs are inserted into both charging ports, and grooves are opened on the top of the rubber plugs. A lever is fixedly installed inside the grooves. A mounting plate is fixedly installed inside the lower shell, and a mounting bracket is fixedly installed at the front end of the mounting plate. A partition is slidably installed inside the mounting bracket, and lithium-ion battery cells are placed on both the front and rear sides of the partition.

[0007] In a preferred embodiment, temperature sensors are provided on both sides of the mounting bracket, and detection ports are opened on both sides of the mounting bracket. The two temperature sensors are fixed in the two detection ports respectively, and the detection heads of the temperature sensors are in contact with the surface of the lithium-ion battery cell. The temperature sensors are used to detect the temperature of the lithium-ion battery cell in real time to avoid the temperature from being too high and affecting charging safety.

[0008] In a preferred embodiment, baffles are hinged to both sides of the top of the mounting frame. The baffles are located on the top of the lithium-ion cell, and each baffle is fixed to the mounting frame by fastening bolts. By fixing the baffles with fastening bolts, the baffles press against the top of the lithium-ion cell, which can effectively improve the stability of the lithium-ion cell.

[0009] In a preferred embodiment, each baffle has a groove at its front end, and the baffle can be flipped open by inserting a finger into the groove.

[0010] In a preferred embodiment, a fixing groove is provided at the rear end of the mounting plate, and a control management chip is fixedly installed inside the fixing groove.

[0011] In a preferred embodiment, both the upper shell corners and the lower shell corners are chamfered.

[0012] The technical effects and advantages of this utility model are as follows: 1. The mounting bracket of this utility model is divided into two areas by a partition, which can hold two lithium-ion battery cells, greatly improving the charging capacity. At the same time, the lower shell is equipped with two charging ports and a charging cable, which can charge three devices at the same time and supports the function of charging and discharging simultaneously, effectively meeting the battery life needs of multiple devices when traveling. In addition, the charging port is equipped with a rubber plug, which can prevent dust and impurities from clogging the charging port and affecting subsequent use, and also prevent the charging port from being damaged by collisions with objects. 2. The power bank's outer shell is composed of an upper shell and a lower shell. The power bank has an elegant overall appearance with rounded corners and a frosted outer surface, which provides a certain degree of anti-slip effect. 3. By setting a temperature sensor on the mounting bracket and a control management chip on the mounting plate, the discharge temperature safety can be improved, supporting temperature protection, short circuit protection, RESET protection, overvoltage protection, overcurrent protection, overcharge and over-discharge protection, etc., making it more durable and reliable.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Refer to the instruction manual appendix Figures 1-5This utility model provides a power bank with charging port protection, including an upper shell 1 and a lower shell 2. The lower shell 2 has two charging ports 3 and a charging cable 4 embedded in its side wall. The lower shell 2 has an insertion port 5 on one side, and the connector of the charging cable 4 is inserted into the insertion port 5. Rubber plugs 6 are inserted into the two charging ports 3. The top of the rubber plugs 6 has a groove 7, and a lever 8 is fixedly installed inside the groove 7. A mounting plate 9 is fixedly installed inside the lower shell 2. A mounting bracket 10 is fixedly installed at the front end of the mounting plate 9. A partition 11 is slidably installed inside the mounting bracket 10. Lithium-ion battery cells 12 are placed on both the front and rear sides of the partition 11. The energy density of the lithium-ion battery cells 12 is much higher than that of traditional batteries (such as nickel-cadmium batteries and nickel-metal hydride batteries), which allows them to store more electrical energy in the same volume or weight. In addition, the cycle life of lithium-ion battery cells 12 can generally reach 500-2000 times or more, with a long cycle life.

[0017] Temperature sensors 13 are provided on both sides of the mounting bracket 10, and detection ports 14 are provided on both sides of the mounting bracket 10. The two temperature sensors 13 are fixed in the two detection ports 14 respectively, and the detection head of the temperature sensor 13 is in contact with the surface of the lithium-ion cell 12. Thermistor type temperature sensors can be selected. The resistance value of the thermistor will decrease as the temperature rises. In the power bank, it monitors the battery temperature in real time. When the temperature changes, its resistance value also changes accordingly, and the current or voltage in the circuit will also change accordingly, thereby reflecting the temperature change and realizing the monitoring and control of the temperature of the lithium-ion cell 12.

[0018] The mounting plate 9 has a fixing slot 18 at its rear end. A control management chip 19 is fixedly installed inside the fixing slot 18. The control management chip 19 is an integrated circuit chip used to manage and control various functions in an electronic system. The control management chip 19 adjusts and controls the input voltage and current through various internal circuit modules and algorithms to meet the needs of battery charging and device power supply. The corners of the upper shell 1 and the lower shell 2 are all chamfered.

[0019] In actual use, the upper shell 1 and the lower shell 2 form the outer shell 2 of the power bank. The upper shell 1 and lower shell 2 have an elegant appearance with rounded corners. The entire outer wall of the power bank has a frosted texture, providing some anti-slip properties. Inside the upper shell 1 and lower shell 2, there is a mounting bracket 10. The mounting bracket 10 is divided into two parts by a partition 11, used to hold two 10000mAh lithium-ion battery cells 12. On one side of the lower shell 2, there are two charging ports 3 (TYPC-C and USB-A) and a charging cable 4 (Android connector or Apple connector). Both the charging head and the charging cable 4 support a maximum of 22.5W wired bidirectional charging, saving charging power. With its long charging and self-charging time, it can simultaneously power up three devices and also supports simultaneous charging and discharging, meaning it can power up two other devices while charging itself, solving the battery life needs of multiple devices during travel. It is also equipped with a temperature sensor 13 and an advanced control and management chip 19, ensuring safe discharge temperature and supporting temperature protection, short circuit protection, RESET protection, overvoltage protection, overcurrent protection, overcharge and over-discharge protection, making it more durable and reliable. In addition, when the power bank is not in use, the rubber plugs 6 can be inserted into the two charging ports 3 to prevent dust and impurities from clogging the charging ports 3 and affecting subsequent use, and also to prevent the charging ports 3 from being damaged by collisions with objects.

[0020] Refer to the instruction manual appendix Figure 3 and Figure 4 The mounting bracket 10 has baffles 15 hinged to both sides of its top. The baffles 15 are located on the top of the lithium-ion cell 12. Each baffle 15 is fixed to the mounting bracket 10 by fastening bolts 16. By fixing the baffles 15 with fastening bolts 16, the baffles 15 press against the top of the lithium-ion cell 12, which can effectively improve the stability of the lithium-ion cell 12.

[0021] like Figure 4 As shown, each baffle 15 has a groove 17 at its front end. When it is necessary to disassemble and replace the lithium-ion battery cell 12, first loosen the fastening bolt 16 on the baffle 15, then insert your finger into the groove 17 to flip the baffle 15 open, and then pull the partition 11 to move the two lithium-ion battery cells 12 out of the mounting bracket 10 together. The structure is simple and the replacement is very quick.

[0022] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
