Description

Technical Field

[0001] This invention relates to the field of portable power bank technology, and in particular to a portable power bank with high protection performance. Background Technology

[0002] With the widespread use of modern electronic devices, power banks have become an indispensable portable charging device in daily life. Whether for outdoor adventures, long-distance travel, daily commutes, or office and study use, power banks have won the favor of a wide range of users due to their convenience and practicality.

[0003] In actual use, power banks often face various potential physical damage risks, such as drops, squeezing, and collisions. These external impacts may damage the internal structure of the power bank, thereby affecting its normal operation and lifespan. In addition, power banks are also easily affected by bumps and vibrations during carrying, which may damage their internal circuits and batteries over time. Secondly, when used outdoors, the power bank is prone to moisture damage because it is placed directly on the ground. Moreover, most existing power banks are currently integrated structures, and the various components are installed in a compact manner, which makes it difficult for the power supply to dissipate heat. Therefore, existing power bank technologies still have certain shortcomings. Summary of the Invention

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] Example:

[0041] Reference Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9A portable, high-protection power bank includes a power bank body 100. A top plate 101 and a bottom plate 102 are respectively provided on the top and bottom of the power bank body 100. A handle 104 is provided on the top of the top plate 101. Connecting buffers 200 for connection and protection are provided between the power bank body 100 and the top plate 101, and between the power bank body 100 and the bottom plate 102. A protective plate 103 is provided on the side of the power bank body 100. Elastic connectors 300 for buffering and shock absorption are provided between the protective plate 103 and the top plate 101, and between the protective plate 103 and the bottom plate 102. A supporting and protective component 400 is provided on the side of the power bank body 100, which moves up and down along its sidewall to provide support and protection for the power bank body 100. The connecting buffers 200 and the elastic connectors 300 effectively enhance the overall structural strength of the power bank. This design can significantly resist external impacts such as drops, squeezing, and collisions, protecting the internal structure of the power bank from damage and thus extending its service life. The power bank body 100 is equipped with a heat dissipation component 500 for cooling its internal components. The heat dissipation component 500 adopts a combination of air cooling and liquid cooling, which can improve the airflow inside the power bank body 100, thereby effectively improving the heat dissipation effect of the power bank body 100 and preventing its internal temperature from being too high, which would affect the normal use of the power bank body 100. The bottom of the base plate 102 is equipped with wheels and a handle 104 for easy movement when used outdoors.

[0042] Furthermore, refer to Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9 The support and protection component 400 includes a first connecting seat 401 slidably disposed on the upper side of the power bank body 100, a second connecting seat 402 fixedly disposed on the lower side of the power bank body 100, and a connecting rod assembly 403 movably disposed between the first connecting seat 401 and the second connecting seat 402. A locking member 404 is provided between the first connecting seat 401 and the power bank body 100. Specifically, the power bank body 100 is provided with a dovetail groove 408 that cooperates with the first connecting seat 401, the first connecting seat 401 is provided with a through hole 409, and the power bank body 100 is provided with a threaded hole 410. The locking member 404 is a locking bolt 411 that cooperates with the threaded hole 410. The dovetail groove 408 makes the first connecting seat 401 more stable when moving, and the locking bolt 411 can fix the adjusted support and protection component 400.

[0043] Reference Figure 1 , Figure 2 and Figure 6The top plate 101, bottom plate 102, and protective plate 103 all adopt a frame structure. Furthermore, the outer wall of the power bank body 100 is provided with a power output port 112, a power charging port, a display module 113 for displaying relevant information of the power bank, and a circuit board assembly 111 disposed between the inner shell 106 and the outer shell 105. These are all existing mature technologies and will not be described in detail here. By adopting a frame structure, both the protective effect is ensured and the normal use of charging and data transmission functions is not hindered. A buffer protection gap 204 is formed between the power bank body 100 and the top plate 101, and between the power bank body 100 and the bottom plate 102, through the connecting buffer member 200. The formed buffer protection gap 204 can provide a good buffer space when the power bank body 100 is subjected to external forces such as collisions, so as to ensure a good buffering effect and provide good buffer protection for the power bank body 100, avoiding damage to the power bank body 100.

[0044] Reference Figure 1-9 The connecting buffer 200 includes a mounting base 201 disposed on the top plate 101, the bottom plate 102, and the power bank body 100; a first guide limiting rod 202 disposed through the two mounting bases 201; and a first elastic member 203 sleeved on the first guide limiting rod 202. The first elastic member 203 is disposed between the two mounting bases 201. Through the connecting buffer 200, when external impacts such as drops, squeezing, or collisions occur, the top plate 101, the bottom plate 102, and the first elastic member 203 can play a good buffering and protective role, preventing external impacts from directly acting on the power bank body 100 and causing damage to its internal structure.

[0045] Reference Figure 1 , Figure 3 , Figure 5 , Figure 6 The elastic connector 300 includes a transverse connector 301 connected to the top plate 101 and the bottom plate 102, and a longitudinal connector 303 connected to the transverse connector 301 and the protective plate 103 via a connecting block 302. The transverse connector 301 and the longitudinal connector 303 provide a better buffering effect when the protective plate 103, the top plate 101 and the bottom plate 102 are subjected to external force compression and collision, thereby protecting the power bank body 100.

[0046] The transverse connector 301 includes a second guide limiting rod 304 that passes through the top plate 101 and the bottom plate 102 and a second elastic member 305 that is sleeved on the second guide limiting rod 304. The connecting block 302 is located at the end of the second guide limiting rod 304. The transverse connector 301 can buffer the transverse external force by cooperating with the second elastic member 305.

[0047] The protective plate 103 is provided with longitudinal connecting parts 303 at both the top and bottom. The longitudinal connecting parts 303 include a third guide limit rod 306 and a third elastic element 307 sleeved on the third guide limit rod 306. The longitudinal connecting parts 303 and the third elastic element 307 can buffer the longitudinal external force. Together with the transverse connecting parts 301 and the second elastic element 305, the power bank body 100 is fully protected.

[0048] The third guide limit rod 306, located at the top of the protective plate 103, is connected at one end to the top of the protective plate 103 and extends upward through the connecting block 302 at the other end. The third guide limit rod 306, located at the bottom of the protective plate 103, is connected at one end to the top of the connecting block 302 and extends upward through the protective plate 103 at the other end. Through the provided elastic connector 300, the protective plate 103 can achieve a buffering and protective effect when subjected to lateral or longitudinal external forces. It can also work with the top plate 101 and the bottom plate 102 to provide buffering and shock absorption protection. It can disperse and dissipate the external forces on the top plate 101 and the bottom plate 102, thereby improving the protection effect on the power bank body 100.

[0049] It should be noted that the first guide limit rod 202, the second guide limit rod 304, and the third guide limit rod 306 are all composed of a rod body and a cap threadedly connected to the rod body. The two can be disassembled and assembled. When a connecting buffer 200, elastic connecting part 300, or protective plate 103 is damaged, the user can easily remove it and replace it with a new part, which facilitates maintenance and reduces maintenance costs. Furthermore, the first elastic part 203, the second elastic part 305, and the third elastic part 307 are all springs. Both ends of the springs are provided with shock-absorbing damping pads, which can absorb the vibration energy generated, block the transmission of vibration, and improve the buffering and shock absorption effect.

[0050] Reference Figure 4 , Figures 7-9The linkage assembly 403 includes a first rod 405 rotatably disposed on both sides of the first connecting seat 401 and a second rod 406 rotatably disposed on both sides of the second connecting seat 402. The first rod 405 and the second rod 406 are hinged together by a connecting shaft 407. Specifically, when the first connecting seat 401 is pulled downward, the second connecting seat 402 can drive the first rod 405 and the second rod 406 to rotate relative to each other. When the first rod 405 moves to a lower position, the intersection of the two rods will contact the ground, providing good support for the power bank body 100. When the first connecting seat 401 continues to move downward, the power bank body 100 will be away from the ground and will not contact the ground. At this time, it can achieve good waterproof and moisture-proof effect, preventing the power bank body 100 from getting wet and affecting its normal use.

[0051] Reference Figure 10-15 The power bank body 100 includes an outer shell 105, an inner shell 106, and a battery module 107 disposed inside the inner shell 106 via two mounting plates 108. The heat dissipation assembly 500 includes a heat dissipation fan 501 disposed on the inner wall of the outer shell 105 and connected to its exterior, and a heat dissipation component 502 disposed inside the inner shell 106 and cooperating with the battery module 107. The outer shell 105 has heat dissipation holes 109, and a dustproof mesh 110 is disposed inside the heat dissipation holes 109. Specifically, the inner shell 106 adopts a hollow structure to facilitate heat dissipation, and the heat dissipation fans 501 are symmetrically arranged... The structure, with an intake fan at one end and an exhaust fan at the other, located at both ends of the outer casing 105, improves the airflow inside the power bank body 100, thereby enhancing its heat dissipation. The heat dissipation component 502 absorbs the heat generated inside the power bank body 100, and the heat dissipation fan 501 dissipates the absorbed heat, thus effectively improving its heat dissipation. The dustproof mesh 110 is embedded and detachably mounted on the outer casing 105 and cooperates with the heat dissipation hole 109, which not only provides dust protection but also facilitates disassembly, maintenance, and replacement.

[0052] The heat dissipation component 502 includes a first liquid cooling plate 503 snapped between two mounting plates 108 and a second liquid cooling plate 504 disposed at both ends of the first liquid cooling plate 503 and respectively abutting against the two mounting plates 108. The first and second liquid cooling plates 503 and 504 have interconnected liquid cooling channels 505 forming a loop structure. A circulating cooling pump 506 is disposed on the top of the second liquid cooling plate 504. The first liquid cooling plate 503 has ventilation slots 507 that align with the airflow direction. Specifically, several sets of the first liquid cooling plates 503 can be configured according to specific usage. The ventilation slots on the first liquid cooling plate, combined with a cooling fan, effectively improve the airflow inside the inner casing 106, effectively carrying away the heat generated by the battery module from the inner casing, thus improving heat dissipation and reducing the temperature rise of the power bank body. During use, coolant is injected into the liquid cooling channels 505, and the coolant... While the heat generated by the battery module 107 is carried away, the heat dissipation holes 109, combined with the airflow from the cooling fan 501, not only introduce cool air from outside the power bank body 100 into its interior to cool the battery module 107, but also allow the cool air entering the interior to flow over the surface of the heat dissipation fins 508, further carrying away the heat inside the power bank body 100, reducing the temperature rise of the power bank body 100, and keeping the interior of the power bank body 100 within the operating temperature range, so as not to affect the use and lifespan of the device. Since the liquid cooling channels 505 inside the first liquid cooling plate 503 and the second liquid cooling plate 504 are interconnected, the circulating cooling pump 506 can circulate the coolant inside, further improving the performance of absorbing the heat generated by the battery module 107, thereby effectively improving the cooling effect inside the power bank body 100.

[0053] Both second liquid cooling plates 504 are provided with heat dissipation fins 508. The heat dissipation fins 508 are arranged in an array on the top of the second liquid cooling plates 504 parallel to the gas flow direction. Because the heat dissipation fins 508 are parallel to the gas flow direction, under the action of the cooling fan 501 and in conjunction with the provided heat dissipation holes 109, the air entering the box can quickly flow over the surface of the heat dissipation fins 508, quickly remove the heat absorbed by the heat dissipation fins 508, reduce the temperature rise inside the power bank body 100, and improve the stability of the power bank body 100 during use.

[0054] Specifically, when this portable high-protection power bank is in use: when the power bank is subjected to external impacts such as drops or squeezing, the top plate 101, bottom plate 102, and protective plate 103 form a buffer protection with the power bank body 100 through the connecting buffer member 200 and elastic connector 300. The first guide limit rod 202 and the first elastic member 203 provide buffering between the top plate 101, bottom plate 102, and power bank body 100, reducing the direct impact of the impact force on the internal structure of the power bank. The second guide limit rod 304 and the second elastic member 305 provide lateral buffering between the top plate 101 and bottom plate 102, while the third guide limit rod 306 and the third elastic member 307 provide longitudinal buffering between the protective plate 103 and the top plate 101 and bottom plate 102, further enhancing the stability of the overall structure and supporting the adjustment and fixation of the protective components. In use, the first connecting seat 401 can be moved downward along the dovetail groove 408, which, in conjunction with the provided second connecting seat 402, can drive the second connecting seat 403. The first rod 405 and the second rod 406 rotate until they contact the ground, supporting the power bank body 100 away from the ground. This effectively isolates the power bank body 100 from the ground, preventing moisture and water from contacting it and improving its moisture resistance. Simultaneously, the support and protection component 400 keeps the power bank body 100 in a relatively balanced state, preventing it from tipping over. It should be noted that when the support and protection component 400 needs to be fixed, the first connecting seat 401 is fastened to the threaded hole 410 on the power bank body 100 using a locking component 404, such as a locking bolt 411, ensuring the stability and safety of the support and protection component 400 during use. The top plate 101, bottom plate 102, and protective plate 103 adopt a frame structure, ensuring both protection and unimpeded normal use of charging and data transmission functions.

[0055] When the power bank is in operation, the battery module 107 generates a certain amount of heat. When the cooling fan 501 is activated, it draws in external air and blows it into the housing 105 through the heat dissipation holes 109. Inside the heat dissipation holes 109, a dustproof mesh 110 is installed to prevent dust and debris from entering the power bank and affecting the heat dissipation effect and power safety. The heat dissipation component 502 is located inside the inner housing 106 and cooperates with the battery module 107. The heat dissipation component 502 consists of a first liquid cooling plate 503 and a second liquid cooling plate 504, which are connected between two mounting plates 108 by a snap-fit ​​method. Inside the first liquid cooling plate 503 and the second liquid cooling plate 504, there are interconnected liquid cooling channels 505 in a loop structure. These liquid cooling channels 505 are filled with cold water. When the battery module 107 generates heat, the coolant absorbs this heat and circulates through the liquid cooling channel 505. A circulating cooling pump 506 is installed on the top of the second liquid cooling plate 504. The function of the circulating cooling pump 506 is to drive the coolant to circulate within the liquid cooling channel 505, thereby ensuring that the coolant can continuously absorb heat from the battery module 107 and carry it away. In addition, to further improve the heat dissipation effect, heat dissipation fins 508 are provided on both second liquid cooling plates 504. These heat dissipation fins 508 are arranged in an array parallel to the gas flow direction on the top of the second liquid cooling plate 504. They can increase the heat dissipation area and improve the heat dissipation efficiency. When the air blown in by the cooling fan 501 flows through the heat dissipation fins 508, it will carry away the heat on the heat dissipation fins 508, thereby achieving rapid heat dissipation.
