Description

Technical Field

[0001] This utility model relates to the field of outdoor mobile power supply technology, and in particular to an outdoor energy storage device with short-circuit protection. Background Technology

[0002] With the increasing prevalence of outdoor activities, emergency rescue, and field operations, the safety of outdoor energy storage devices, as the core carriers of power supply, is becoming increasingly critical. Currently, traditional outdoor energy storage devices have many shortcomings in short-circuit protection. Complex outdoor environments such as humidity, dust, and severe vibration can easily lead to aging of internal wiring and loosening of interfaces, thereby causing short-circuit faults.

[0003] A search revealed Chinese Patent Publication No. CN219046425U, which discloses an outdoor portable power supply device belonging to the field of outdoor portable power supply technology. The device includes a protective housing, inside which is a power storage unit. The inner wall of the protective housing is equipped with a convenient heat dissipation component, and one side of the protective housing has a fixed baffle. Inside the fixed baffle, an adjustable protective component is installed. This invention, by setting an adjustable protective component, allows for convenient and stable adjustment of the sliding baffle, improving the safety of the power storage unit, ensuring the convenience of adjusting the sliding baffle, and enhancing the device's performance. Simultaneously, the sliding baffle will not vibrate or shake during the use of the power storage unit while in motion. The convenient heat dissipation component cools the power storage unit during operation, preventing overheating and short circuits in hot weather, ensuring the stability of the device's operation, and extending its service life.

[0004] The aforementioned patent specification mentions that "during the operation of the energy storage power supply body 3, the exhaust fan 24 is activated to draw air into the protective housing 1. The air is filtered and dehumidified by the grid mesh 22 and the sponge moisture-absorbing mesh 23 before being blown onto the energy storage power supply body 3 to cool it down, and then discharged from the perforated plate 26, ensuring the stability of the energy storage power supply body 3 when used outdoors in hot weather, improving the service life of the equipment, and ensuring the quality of work." However, for outdoor energy storage devices that need to be connected to external equipment, it is necessary to ensure that the connection is firm and reliable to prevent short circuits caused by electric sparks due to loosening. Due to the characteristics of the outdoor environment, such as high vibration, wind and sand, and large temperature difference, traditional connection methods are prone to loosening. Once the connection is loose, it will not only lead to unstable power transmission and affect the normal operation of the equipment, but more seriously, electric sparks will be generated at the connection, resulting in short circuits. In response to the above problems, an outdoor energy storage device with short circuit prevention is proposed. Utility Model Content

[0005] This invention proposes an outdoor energy storage device with short-circuit prevention features, aiming to improve the problem of short circuits caused by loose connections in some existing devices.

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

[0007] An outdoor energy storage device with short-circuit protection includes a protective housing. A clamping and fixing mechanism is fixedly connected to the outside of the protective housing. Heat dissipation mechanisms are fixedly connected to the left and right sides of the protective housing. The clamping and fixing mechanism includes a fixing component for fixing. The fixing component is fixedly connected to the outside of the protective housing. A connecting fixing post is fixedly connected to the outside of the fixing component. A connecting rotating rod is fixedly connected to the outside of the connecting fixing post. A connecting fixing block is fixedly connected to the outside of the connecting rotating rod. A connecting support block is fixedly connected to the outside of the connecting fixing block, i.e., the end away from the connecting rotating rod. A connecting sliding ring is fixedly connected to the outside of the connecting support block, i.e., the end away from the connecting fixing block.

[0008] Through the above scheme, the clamping and fixing mechanism links the connecting fixing column, rotating rod, fixing block and other components, so that the connecting sliding ring can adaptively clamp the charging cable, avoiding short circuits caused by electrical sparks due to looseness. The stable connection can also reduce local overheating caused by poor contact, reducing the risk of short circuits from the source. The protective shell and heat dissipation mechanism work together, and the high-strength shell resists damage to the internal circuits from outdoor collisions, sand and dust and other environmental factors, reducing the possibility of short circuits due to circuit damage. The heat dissipation mechanisms on the left and right sides dissipate heat in time, preventing short circuits caused by aging of circuit components and deterioration of insulation performance due to high temperature.

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

[0010] The heat dissipation mechanism includes a heat dissipation fin, a connecting copper pipe is fixedly connected to the outside of the heat dissipation fin, and a fixing connecting block is fixedly connected to the bottom of the connecting copper pipe.

[0011] The above solution provides a complete heat dissipation chain that absorbs and efficiently conducts heat to a uniformly distributed source, ensuring stable and reliable basic heat dissipation for outdoor energy storage devices and effectively reducing the risk of short circuits caused by high temperatures.

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

[0013] A connecting rotating ring is fixedly connected to the outside of the connecting fixed column, and a sector gear is fixedly connected to the outside of the connecting rotating ring.

[0014] Through the above scheme, the connecting fixed column, connecting rotating ring, and sector gear, through reasonable structural design and assembly process, form an efficient and stable power transmission and control system, providing a strong guarantee for the safe and reliable operation of outdoor energy storage equipment.

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

[0016] The fixing component includes a rotating motor, the drive end of which is fixedly connected to a rotating connecting column, and the outside of the rotating connecting column is fixedly connected to the inside of the connecting rotating ring.

[0017] Through the above solution, the tight cooperation between the rotating motor and the rotating connecting column enables the fixing component to stably and efficiently transmit power to the connecting rotating ring, driving the entire clamping and fixing mechanism to operate, thereby achieving automatic and reliable fixing of the charging connection cable and effectively preventing short circuit problems caused by loose connections.

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

[0019] The rotating motor is externally fixedly connected to the outside of the protective housing, and the sector gear is externally fixedly connected to the outside of the protective housing.

[0020] The above solution integrates the rotating motor and sector gear into the protective housing, which not only improves the structural stability of the outdoor energy storage equipment, but also enhances the safety performance against short circuits, ensuring reliable operation of the equipment in complex environments.

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

[0022] The outer side of the protective shell is fixedly connected to the outside of the protective shell, the connecting sliding ring is slidably connected to the outside of the protective shell, the inner side of the connecting sliding ring is slidably connected to a charging port, and the outer side of the charging port is fixedly connected to the inside of the protective shell.

[0023] The above solution provides a stable mounting base and protective barrier for the connecting sliding ring and the charging port. The connecting sliding ring clamps the charging cable, while the charging port ensures safe and stable power transmission, thus improving the short-circuit protection and reliability of outdoor energy storage devices.

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

[0025] A cooling fan is fixedly connected to the outside of the first heat sink fin, and a second heat sink fin is fixedly connected to the outside of the first heat sink fin, i.e., the end away from the first heat sink fin. The bottom of the second heat sink fin is fixedly connected to the outside of the fixed connecting block.

[0026] Through the above solution, the heat dissipation fin one, the heat dissipation fan one, the heat dissipation fin two, and the fixed connecting block are connected and work together to form a high-efficiency heat dissipation system, which can effectively reduce the temperature of outdoor energy storage equipment and ensure the stable operation of the equipment.

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

[0028] The second heat sink fin is fixedly connected to the outer end of the second heat sink fin, that is, the end away from the first heat sink fan. The second heat sink fan is fixedly connected to the outer end of the second heat sink fin, that is, the end away from the second heat sink fin. Two connecting copper pipes are fixedly connected to the outer side of the connecting heat sink fin. The bottom of the connecting copper pipes is fixedly connected to the inside of the fixed connecting block.

[0029] Through the above scheme, the second heat dissipation fin, the second heat dissipation fan, the connecting heat dissipation fin, the second connecting copper pipe, and the fixed connecting block are reasonably connected and work together to form an efficient multi-level heat dissipation system, which can effectively reduce the temperature of outdoor energy storage equipment and ensure the stable operation of the equipment.

A connecting support block 207 is fixedly connected to the outside of the connecting fixing block 205, that is, the end away from the connecting rotating rod 204. The connecting support block 207 is fixed to the end of the connecting fixing block 205 away from the connecting rotating rod 204 and will move with the movement of the connecting fixing block 205. A connecting sliding ring 208 is fixedly connected to the outside of the connecting support block 207, that is, the end away from the connecting fixing block 205. The connecting sliding ring 208 is fixedly connected to the connecting support block 207 and slidably connected to the outside of the protective shell 1.

[0042] A connecting rotating ring 202 is fixedly connected to the outside of the connecting fixed column 203. The rotating ring 20102 rotates with the rotating connecting column 20102. A sector gear 206 is fixedly connected to the outside of the connecting rotating ring 202. The sector gear 206 is fixed to the outside of the connecting rotating ring 202 and rotates with the connecting rotating ring 202. The fixing assembly 201 includes a rotating motor 20101, which serves as a power source and will start operating when charging is required. The driving end of the rotating motor 20101 is fixedly connected to the rotating connecting column 20102, which is the transmission medium between the rotating motor 20101 and the connecting rotating ring 202.

[0043] The external of the rotating connecting column 20102 is fixedly connected to the inside of the connecting rotating ring 202. The external of the rotating motor 20101 is fixedly connected to the outside of the protective shell 1.

Its external side is slidably connected to the inside of the connecting sliding ring 208. The external side of the charging port 209 is fixedly connected to the inside of the protective shell 1.

[0044] Specifically, the outdoor energy storage device mainly consists of a protective shell 1, a clamping and fixing mechanism 2, and a heat dissipation mechanism 3. The protective shell 1 is the basic frame of the entire device, providing physical protection for the internal components and preventing them from being damaged by external factors such as collisions, sand, and rain. The clamping and fixing mechanism 2 is installed on the outside of the protective shell 1 and is mainly used to securely fix the charging connection cable during the charging process to avoid short circuits caused by loose connections. The heat dissipation mechanism 3 is fixed on the left and right sides of the protective shell 1 respectively, and is responsible for timely dissipating the heat generated during the operation of the device, maintaining the device within a safe temperature range, and reducing the possibility of short circuits caused by overheating.

[0045] Reference Figure 1 , Figure 4The heat dissipation mechanism 3 includes a heat dissipation fin 301, which is fixed to one side of the protective shell 1. It has a large surface area, which can increase the contact area with air and thus improve the heat dissipation efficiency. A connecting copper pipe 302 is fixedly connected to the outside of the heat dissipation fin 301. The bottom of the connecting copper pipe 302 is connected to a fixed connecting block 303. The fixed connecting block 303 is fixedly connected to the bottom of the connecting copper pipe 302 and the bottom of the connecting copper pipe 308. A cooling fan 305 is fixedly connected to the outside of the heat dissipation fin 301. When the heat dissipation fin 301 absorbs heat, the cooling fan 305 can blow the surrounding cold air toward the heat dissipation fin 301 to remove the heat and further improve the heat dissipation effect.

[0046] A second heatsink fin 304 is fixedly connected to the outer end of cooling fan 305, i.e., the end furthest from cooling fin 301. Cooling fin 304 is fixed to the outer end of cooling fan 305, furthest from cooling fin 301, and its bottom is connected to the outer side of fixing block 303. A second heatsink fin 306 is fixedly connected to the outer end of cooling fin 304, i.e., the end furthest from cooling fan 305. Cooling fan 306 is fixed to the outer end of cooling fin 304, furthest from cooling fan 305. A connecting heat sink 307 is fixedly connected to the outer end of the cooling fan 306, that is, the end away from the second heat sink 304. The connecting heat sink 307 is fixed to the end of the cooling fan 306 away from the second heat sink 304, which can further increase the heat dissipation area and improve the heat dissipation efficiency of the entire heat dissipation mechanism 3. Two connecting copper pipes 308 are fixedly connected to the outer side of the connecting heat sink 307. The bottom of the connecting copper pipes 308 is fixedly connected to the inside of the fixed connecting block 303.

[0047] Specifically, by using a composite heat dissipation mode, the heat dissipation efficiency is improved compared to traditional heat dissipation structures. This can keep the temperature of the core components of the equipment within a safe range, effectively avoiding problems such as short circuits and component aging caused by high temperatures, and significantly improving the reliability and service life of outdoor energy storage equipment.

[0048] Working principle: When charging is required, the rotation of motor 20101 drives the rotation of rotating connecting column 20102, which in turn drives the rotation of connecting fixing column 203, which in turn drives the rotation of connecting rotating ring 202, which in turn drives the rotation of sector gear 206. At the same time, connecting rotating rod 204 rotates together with connecting fixing column 203, which drives the rotation of connecting fixing block 205 and connecting support block 207, thereby causing the connecting sliding ring 208 to move inward, thus fixing the charging connection cable, ensuring a firm and reliable connection, and preventing short circuits caused by electrical sparks due to loosening.

[0049] When the internal temperature of the protective casing 1 rises, the rotation of cooling fan 1 305 and cooling fan 2 306 increases the airflow speed inside the heat dissipation fin 2 304, thereby increasing the heat dissipation efficiency. At the same time, the fixing connection block 303 provides support for the heat dissipation fin 2 304, and the connecting copper pipe 1 302 connects the heat dissipation fin 1 301 to increase the heat dissipation efficiency. Meanwhile, the connecting copper pipe 2 308 provides support and fixation for the connecting heat dissipation fin 307, ensuring the normal operation of the energy storage device and ensuring that the device can maintain good heat dissipation performance during long-term use, avoiding circuit failure and short circuit due to overheating.

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.
