Description

A portable energy storage power source suitable for different terrains Technical Field

[0001] This utility model relates to the field of energy storage power technology, and in particular to a portable energy storage power supply suitable for different terrains. Background Technology

[0002] With the continuous expansion of outdoor activities, emergency rescue, and field operations, the demand for portable energy storage power supplies is increasing. Driven by the global goal of carbon neutrality, the mobile application of clean energy has become a development trend. Portable energy storage power supplies, as green devices to replace traditional fuel generators, are widely used in camping trips, outdoor live broadcasts, and disaster relief due to their environmental protection and quiet operation. However, different terrain conditions place higher demands on the applicability and stability of portable energy storage power supplies, prompting the industry to continuously explore and innovate.

[0003] A search revealed that Chinese Publication No. CN221748011U discloses a portable energy storage power supply. Users connect the portable energy storage power supply to external devices requiring support or fixation (such as cameras, external spotlights, etc.) via a fixing screw hole. The fixing thread engages with the corresponding fixing components (such as bolts) of the external device to ensure a secure connection. Once fixed, the energy storage power supply not only provides energy but also stabilizes and supports the external device. The integrated fixing screw hole makes the portable energy storage power supply more suitable for outdoor use, reducing the need for carrying additional support or fixing devices. The centrally located fixing screw hole helps maintain the stability of both the energy storage power supply and the connected device, especially in uneven outdoor environments. This not only enables the energy storage power supply to power the device but also allows it to serve as a physical support point, increasing the device's usability and flexibility.

[0004] The aforementioned patent mentions that "the design of the center position of the fixing screw hole helps maintain the stability of the energy storage power supply and the connected equipment, especially in uneven outdoor environments. It not only enables the energy storage power supply to power the equipment, but also allows it to serve as a physical support point, increasing the equipment's usage scenarios and flexibility." However, in the prior art, while the energy storage power supply can power the equipment and serve as a physical support point, increasing the equipment's usage scenarios and flexibility, it can only power small devices. When a large amount of power is needed, the existing technology is suitable for flat ground, but lacks stability when placed on complex terrain, causing it to tilt and resulting in unstable power supply. Therefore, a portable energy storage power supply suitable for different terrains is proposed to solve the above problems. Summary of the Invention

[0005] This invention proposes a portable energy storage power supply suitable for different terrains, aiming to improve the instability of some existing devices when placed in different terrains.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A portable energy storage power supply suitable for different terrains includes a housing, an internal protective mechanism, a support mechanism at the bottom inner side of the housing, a portable handle fixedly connected to the top of the housing, and a waterproof mechanism on one side of the external interface of the housing. The support mechanism includes a telescopic rod and a moving component. The telescopic rod is externally fixedly connected to the inside of the housing, and the moving component is externally fixedly connected to the inside of the four bottom corners of the housing. A connecting ring is fixedly connected to the driving end of the telescopic rod, and four connecting posts are fixedly connected to the outside of the connecting ring. A sliding hollow column is slidably connected to the bottom of each connecting post, and a fixed suction cup is fixedly connected to the bottom of each sliding hollow column.

[0008] With the above solution: when the user moves the power bank with the portable handle, the moving components inside the four corners of the bottom of the casing facilitate pushing it on different terrains. After reaching the target location, the telescopic rod drive end inside the casing moves the connecting ring downwards. The four connecting pillars pull the sliding hollow pillars to extend from the bottom of the connecting pillars, allowing the bottom fixing suction cup to adhere to the ground, thus achieving stable fixation of the power bank on complex terrains. At the same time, the protective mechanism inside the casing can protect the internal components, and the waterproof mechanism on the external interface side can prevent water vapor and dust from entering the interface.

[0009] As a further description of the above technical solution:

[0010] The protective mechanism includes a heat sink plate, which is externally fixedly connected to the inside of the outer casing. A power supply body is provided on the top of the heat sink plate, and peak-shaped holes are formed inside the heat sink plate in an array.

[0011] The above solution works as follows: when the main power supply generates heat, the heat is conducted through a heat sink fixedly connected inside the casing. The array of peak-shaped holes inside the heat sink increases the heat dissipation area, accelerates air convection, and quickly dissipates the heat to the outside of the casing.

[0012] As a further description of the above technical solution:

[0013] The moving component includes a cylinder, the cylinder being fixedly connected to the inside of the four corners of the bottom side of the housing, and a connecting sliding plate being fixedly connected to the driving end of the cylinder.

[0014] The above solution allows the power supply to be moved or parked in various terrains when needed. The cylinders inside the four corners of the bottom of the casing drive the connecting sliding plate to slide in the holes at the bottom of the casing. This allows the pulleys at the bottom of the connecting sliding plate to extend or retract, thereby improving the power supply's mobility and stability in complex terrains and meeting the needs of all-terrain use.

[0015] As a further description of the above technical solution:

[0016] The bottom four corners of the outer casing are provided with holes, and the outside of the connecting sliding plate is slidably connected to the inside of the four corner holes of the outer casing. The bottom of the connecting sliding plate is fixedly connected with a pulley.

[0017] The above solution allows the power supply to slide when it needs to be moved. The sliding plate slides through the holes at the four corners of the bottom of the casing, causing the fixed pulleys at the bottom to extend out of the bottom of the casing. This allows the power supply to slide by contacting the ground through the pulleys. When it does not need to be moved, the sliding plate slides in the opposite direction, and the pulleys retract into the holes at the bottom of the casing. This enables the power supply to be easily moved and parked on flat terrain, reducing the burden of manual handling and improving the flexibility of use in all terrains.

[0018] As a further description of the above technical solution:

[0019] A connecting circular plate is fixedly connected to the bottom of the heat sink at opposite corners. A hydraulic column is fixedly connected to the bottom of the connecting circular plate. Another connecting circular plate is fixedly connected to the driving end of the hydraulic column. A buffer spring is sleeved on the opposite side of the two connecting circular plates, i.e., the outside of the hydraulic column.

[0020] The above solution works as follows: when the power supply is subjected to external vibration or collision, the connecting circular plate at the bottom of the diagonal of the heat sink moves with the vibration, causing the hydraulic column to extend and retract. At the same time, the buffer spring sleeved outside the hydraulic column is compressed or extended between the two connecting circular plates to absorb and buffer the vibration energy, thereby achieving shock absorption protection for the heat sink and the main body of the power supply above, reducing the impact of vibration on internal components, and improving the structural stability of the power supply under complex scenarios such as bumps and drops.

[0021] As a further description of the above technical solution:

[0022] Two cooling fans are located directly below the heat sink, at the bottom of the casing.

[0023] The above solution works as follows: when the heat generated by the power supply unit is conducted downwards through the heat sink, the two cooling fans at the bottom of the casing start. The fan blades rotate to accelerate airflow, and the heat dissipated by the heat sink is discharged to the outside through the opening at the bottom of the casing. This effectively reduces the operating temperature of the power supply unit, avoids performance degradation caused by high temperature, and improves the reliability of the power supply under high load operation.

[0024] As a further description of the above technical solution:

[0025] The waterproof mechanism includes a hinge, which is externally fixedly connected to the outside of the housing, and a transparent waterproof cover is externally fixedly connected to the hinge.

[0026] The above solution allows for the following: When the power interface is not in use, a transparent waterproof cover is attached to the outside of the interface via a hinge, and the hinge rotates to achieve a closed seal. When the interface needs to be used, the user can lift the transparent waterproof cover via the hinge to achieve waterproof and dustproof protection for the external power interface, preventing moisture, dust and other foreign objects from entering the interface and causing short circuits, thus improving the safety and reliability of the interface in complex environments.

[0027] As a further description of the above technical solution:

[0028] The bottom of the transparent waterproof cover is provided with multiple limiting blocks, and the outer shell has multiple holes on the insertion side. The limiting blocks are engaged with the holes on the outside of the outer shell.

[0029] The above solution works as follows: when the transparent waterproof cover is closed, multiple limiting blocks at its bottom align with and engage with multiple holes on one side of the outer casing, forming a tight limiting engagement structure; when the interface needs to be opened, the user applies external force to disengage the limiting blocks from the holes in the outer casing, thus opening the waterproof cover. This effectively prevents rainwater, sand, and other foreign objects from entering through the interface gaps, improving the interface protection performance of the power supply in humid and dusty environments.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, on flat terrain, the cylinder drives the pulley to extend, allowing the power supply to slide easily through the pulley. Compared with the traditional pulleyless design, this significantly reduces the manpower required for movement, making it especially suitable for outdoor camping, exhibition setup, and other scenarios where the power supply needs to be moved frequently. After reaching the target location, the telescopic rod drives the fixed suction cup to adhere to the ground. This fixing method ensures the stability of the power supply on flat ground and can adapt to various surface materials such as rocks and tiles, preventing the power supply from tipping over due to uneven ground or external impact. Compared with the traditional method of simply relying on gravity for placement, the stability is improved.

[0032] 2. This utility model provides comprehensive protection for the power supply unit from both shock absorption and heat dissipation aspects. The peak-shaped perforation design inside the heat sink increases the effective heat dissipation area compared to traditional flat heat dissipation structures. Combined with the intelligent start of the cooling fan, it avoids battery performance degradation and component aging caused by high temperatures, extending the power supply's lifespan. The buffer structure composed of hydraulic columns and buffer springs can effectively absorb vibrations and impacts from all directions, ensuring the safe and stable operation of the power supply unit even in rugged mountain road transportation or accidental outdoor collision scenarios, guaranteeing the user's power reliability and equipment safety.

[0041] 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.

[0042] Referring to Figures 2, 5, and 6, one embodiment of this utility model is provided: a portable energy storage power supply suitable for different terrains, including a shell 1. The shell 1 is made of high-strength engineering plastic, effectively resisting rain and sand erosion. A protective mechanism 6 is provided inside the shell 1, and a support mechanism 5 is provided on the inner bottom of the shell 1. A portable handle 2 is fixedly connected to the top of the shell 1. The surface of the portable handle 2 has anti-slip texture to improve grip comfort. A waterproof mechanism 3 is provided on one side of the external interface of the shell 1. The support mechanism 5 includes a telescopic rod 501 and a moving component 506. The telescopic rod 501 is externally fixedly connected to the inside of the shell 1 around its perimeter. The moving component 506 is externally fixedly connected to the inside of the four corners of the bottom side of the shell 1. Integrated air pressure sensors are provided inside the four corners of the bottom side of the shell 1 to monitor the flatness of the terrain in real time. A connecting ring 502 is fixedly connected to the driving end of the telescopic rod 501. The connecting ring 502 is a ring gear transmission structure. The telescopic rod 501 is used to push the connecting ring 502 to move up and down. The connecting ring 502 is externally fixedly connected to... There are four connecting posts 503, forming a stable tetrahedral structure. A sliding hollow post 504 is slidably connected to the bottom of each connecting post 503. The sliding hollow post 504 adjusts the height of the support feet adaptively through friction. A fixed suction cup 505 is fixedly connected to the bottom of the sliding hollow post 504, employing vacuum adsorption for enhanced stability. The moving component 506 includes a cylinder 50601, which is externally fixedly connected to the four corners of the bottom side of the outer casing 1. A connecting sliding plate 50602 is fixedly connected to the drive end of 50601. The cylinder 50601 is used to push the connecting sliding plate 50602. Holes are provided at the four corners of the bottom of the housing 1. The outside of the connecting sliding plate 50602 is slidably connected to the inside of the four corner holes of the housing 1. A pulley 50603 is fixedly connected to the bottom of the connecting sliding plate 50602. The connecting sliding plate 50602 is used to slide and push out the pulley 50603 inside the four corner holes of the housing 1. The pulley 50603 is used to facilitate the movement of the power supply.

[0043] Specifically, when the power supply needs to be moved, the cylinders 50601 at the four corners of the bottom of the outer casing 1 push the connecting sliding plate 50602, causing it to slide along the bottom hole of the outer casing 1, pushing the bottom pulley 50603 to contact the ground. The pulley 50603 is made of wear-resistant polyurethane. The user pulls the power supply through the top portable handle 2. The portable handle 2 has an anti-slip texture design, enabling convenient movement on flat terrain. After reaching the target location, the telescopic rods 501 around the outer casing 1 push the connecting ring 502 downwards, which drives the four connecting posts 503 to move the power supply. The sliding hollow column 504 descends, causing the bottom fixed suction cup 505 to contact the ground and adhere. In conjunction with the integrated air pressure sensor, the flatness of the terrain is monitored in real time to ensure that the power supply can be stably parked on complex terrains such as slopes and rocks. When the power supply body 4 is working, heat is conducted through the heat sink 601. The heat sink 601 has built-in peak-shaped holes 602. The bottom cooling fan 606 is activated to accelerate air convection. The external interface is sealed by the transparent waterproof cover 302 of the waterproof mechanism 3 with the limiting block 303 engaging with the holes of the outer shell 1 to prevent water vapor and sand from entering.

[0044] Referring to Figures 1 to 3, the protective mechanism 6 includes a heat sink 601, which is externally fixedly connected to the inside of the outer shell 1. A power supply unit 4 is mounted on the top of the heat sink 601. The heat sink 601 is made of a high thermal conductivity aluminum alloy, whose excellent thermal conductivity allows it to quickly conduct the heat generated by the power supply unit 4, providing efficient heat dissipation. The heat sink 601 has peak-shaped holes 602 arranged in an array, increasing the heat dissipation area and facilitating air convection within the holes, thus accelerating heat dissipation. A connecting circular plate 603 is fixedly connected to the diagonal bottom of the heat sink 601. The connecting circular plate 603 connects the heat sink 601 and the hydraulic column 604, ensuring the stability of the structural connection and allowing the hydraulic column 604 to effectively buffer and protect the heat sink 601 and the power supply unit 4 on it. The bottom of the connecting circular plate 603 is fixedly connected to the hydraulic column 604, which has good thermal conductivity. With good buffering performance, when the power supply is subjected to external vibration or impact, the hydraulic column 604 can absorb and disperse energy through the flow and compression of the internal liquid, reducing the impact of vibration on the power supply body 4. The drive end of the hydraulic column 604 is fixedly connected to another connecting circular plate 603. A buffer spring 605 is sleeved on the opposite side of the two connecting circular plates 603, i.e. the outside of the hydraulic column 604. The buffer spring 605 and the hydraulic column 604 work together. When subjected to vibration, the spring will first undergo elastic deformation to initially buffer the energy. Then the hydraulic column 604 will further play its role. The two work together to enhance the overall buffering effect. Two cooling fans 606 are set directly below the heat sink 601, i.e. the bottom of the outer shell 1. The cooling fans 606 can automatically adjust their speed according to the temperature of the power supply body 4. When the power supply temperature is high, the fan runs at high speed to accelerate the air flow and quickly expel the heat dissipated by the heat sink 601 from the outer shell 1, effectively reducing the operating temperature of the power supply body 4 and ensuring that the power supply operates in a stable temperature environment.

[0045] Specifically, the power supply body 4 generates heat during operation, and the heat sink 601, made of highly thermally conductive aluminum alloy, quickly conducts the heat. The internal array of peak-shaped holes 602 increases the heat dissipation area and promotes air convection. When the power supply temperature rises, the two cooling fans 606 at the bottom of the outer casing 1, directly below the heat sink 601, automatically adjust their speed according to the temperature, running at high speed to accelerate airflow and quickly expel heat from the outer casing 1. When the power supply is subjected to external vibration or impact, the buffer spring 605 first undergoes elastic deformation to initially buffer the energy. Subsequently, the hydraulic column 604 further absorbs and disperses the energy through the flow and compression of the internal liquid, reducing the impact of vibration on the power supply body 4.

[0046] Referring to Figures 1 and 4, the waterproof mechanism 3 includes a hinge 301, which is made of stainless steel and has a nano-ceramic coating. The hinge shaft has a built-in fluororubber sealing ring. The hinge 301 is externally fixed to the outside of the outer shell 1. A transparent waterproof cover 302 is externally fixed to the hinge 301. The transparent waterproof cover 302 is made of polycarbonate sheet. Multiple limiting blocks 303 are provided at the bottom of the transparent waterproof cover 302. The four trapezoidal limiting blocks 303 are made of EPDM rubber with laser-engraved anti-slip texture on the surface. The trapezoidal bevels form an interference fit with the trapezoidal slot on the insertion side of the outer shell 1. Multiple holes are provided on the insertion side of the outer shell 1. The limiting blocks 303 are engaged with the holes on the outside of the outer shell 1.

[0047] Specifically, the user lifts the transparent waterproof cover 302 outward through the hinge 301 to expose the power interface of the outer shell 1 for device connection. After connection, the transparent waterproof cover 302 is rotated to the closed position along the hinge 301, and the four trapezoidal limiting blocks 303 at the bottom are inserted into the trapezoidal slots on the insertion side of the outer shell 1. The limiting blocks 303 are squeezed and deformed with the slots, triggering the annular silicone sealing strip at the bottom of the slots to achieve double waterproof sealing. At the same time, the drainage hole design ensures that any seepage liquid is automatically discharged.

[0048] Working principle: When the user moves the portable power supply to different terrains, on flat terrain, the cylinder 50601 pushes the connecting sliding plate 50602 to slide in the holes at the four corners of the bottom of the outer shell 1, so that the pulley 50603 at the bottom of the connecting sliding plate 50602 extends out of the bottom of the outer shell 1. At this time, the user can pull or push the power supply through the portable handle 2 and slide it on the ground using the pulley 50603, easily realizing the movement of the power supply on flat ground. When the power supply reaches the target position, the telescopic rod 501 drives the connecting ring 502 to move downward. The connecting ring 502 drives the sliding hollow column 504 to extend downward through the four connecting columns 503 until the fixed suction cup 505 contacts the ground. Then, the fixed suction cup 505 uses atmospheric pressure to adhere to the ground, realizing the stable fixation of the power supply on different terrains.

[0049] During operation, the power supply body 4 is placed on the heat sink 601. When the power supply body 4 generates heat, the heat is conducted through the heat sink 601. The array of peak-shaped holes 602 inside the heat sink 601 increases the heat dissipation area and accelerates heat dissipation. At the same time, the hydraulic column 604 and the buffer spring 605 at the bottom of the diagonal corner of the heat sink 601 together form a buffer structure. When the power supply is subjected to external vibration or collision, the hydraulic column 604 can extend and retract, and the buffer spring 605 can be compressed and deformed to absorb vibration energy, reduce the impact of vibration on the power supply body 4, and protect the internal components of the power supply. Meanwhile, the two cooling fans 606 at the bottom of the outer casing 1 directly below the heat sink 601 will be activated according to the feedback of the internal temperature sensor of the power supply. The cooling fans 606 start running, accelerate the air flow, and quickly expel the heat dissipated by the heat sink 601 from the outer casing 1, further reducing the temperature of the power supply body 4, ensuring that the power supply operates in a stable temperature environment and extending its service life.

[0050] In humid environments or when exposed to rain, the waterproof mechanism 3 ensures the safety of the external power interface. When the power supply is idle or the interface is not in use, the transparent waterproof cover 302 covers the interface of the outer shell 1 through the hinge 301. The limiting block 303 at the bottom of the transparent waterproof cover 302 engages with the hole on the side of the socket of the outer shell 1 to form a tight sealing structure, effectively preventing rainwater, dust and other substances from entering the interface and preventing short circuits and other malfunctions caused by moisture or foreign objects entering the interface.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
