Description

Technical Field

[0001] This application relates to the field of power storage and mobile power technology, and in particular to an outdoor mobile power supply. Background Technology

[0002] In modern life, portable power banks play a vital role in outdoor activities and emergency power supply scenarios due to their convenience. As one of the core components of portable power banks, the inverter is responsible for converting the DC power stored in the battery into AC power to meet the power needs of various electrical appliances.

[0003] However, in pursuit of portability and space utilization, existing outdoor portable power banks often place the inverter near the battery, power socket, and monitor. Because the inverter's energy conversion efficiency is not 100%, some electrical energy is converted into heat during operation, causing its own temperature to rise continuously. When the inverter is close to the battery, it directly affects the battery's cycle life. The heat generated by the inverter also accelerates the aging and deformation of the power socket's plastic casing, reducing its mechanical strength and insulation performance, and increasing the probability of safety hazards such as short circuits and leakage. Summary of the Invention

[0004] In order to overcome the shortcomings of existing outdoor portable power banks where the heat generated by the inverter affects the battery, power socket, and display, this application provides an outdoor portable power bank that can achieve the effect of isolating the inverter from the battery, power socket, and display.

[0005] To achieve the above objectives, this application adopts the following technical solution: an outdoor portable power supply, comprising a housing and a battery body, characterized in that the housing is provided with a front partition and a rear partition arranged vertically at intervals, the front partition and the rear partition dividing the space inside the housing into a first electrical installation cavity, a battery installation cavity and a second electrical installation cavity arranged sequentially from front to back, a power socket and a display are provided on the front side of the housing, the power socket and display are partially located in the first electrical installation cavity, the battery body is detachably installed in the battery installation cavity, and an inverter is installed in the second electrical installation cavity.

[0006] By adopting the above technical solution, this application has the following advantages: Installing the inverter in the second electrical mounting cavity isolates it from the battery mounting cavity where the battery body is located, preventing the heat generated by the inverter during operation from directly affecting the battery. This reduces the adverse effects of temperature increases on battery cycle life and helps the inverter dissipate heat, eliminating concerns about the dissipated heat affecting other electrical components, thus extending battery life and ensuring the energy storage performance and overall usage time of the power bank. Furthermore, the power socket and display structures are located in the first electrical mounting cavity, separated from the inverter located in the second electrical mounting cavity. The heat generated by the inverter will not affect the power socket or display, effectively maintaining the mechanical strength and insulation performance of the socket, reducing the probability of short circuits, leakage, and other safety hazards, and effectively preventing the inverter's heat from affecting the display, thus improving the safety of the power bank during use. Finally, placing the heaviest battery body in the centrally located battery mounting cavity ensures the overall center of the outdoor power bank is in the middle, guaranteeing greater stability during transport and reducing the risk of shaking and danger.

[0007] Furthermore, the bottom of the enclosure is provided with a first heat dissipation vent and a cooling fan. The first heat dissipation vent connects the second electrical installation cavity and the outside of the enclosure. The cooling fan is located at a position corresponding to the first heat dissipation vent. The side wall of the enclosure is provided with a second heat dissipation vent, which connects the second electrical installation cavity and the outside of the enclosure.

[0008] By employing the aforementioned technical solution, an effective heat dissipation channel is formed by installing a first heat dissipation vent and a cooling fan at the bottom of the enclosure, and a second heat dissipation vent on the side wall. The cooling fan actively draws the heat generated by the inverter inside the second electrical installation cavity out through the first heat dissipation vent, and, in conjunction with the second heat dissipation vent on the side wall, accelerates airflow, allowing heat to dissipate to the outside of the enclosure more quickly. This significantly reduces the inverter's operating temperature, preventing performance degradation or malfunction due to overheating, ensuring the inverter always operates within a suitable temperature range, thereby improving its efficiency and stability, and extending its service life.

[0009] Furthermore, the bottom of the housing is provided with a first heat dissipation vent and a cooling fan. The first heat dissipation vent connects the second electrical appliance mounting cavity and the outside of the housing. The cooling fan is located at a position corresponding to the first heat dissipation vent. The side wall of the housing is provided with a second heat dissipation vent, which connects the first electrical appliance mounting cavity and the outside of the housing. The first electrical appliance mounting cavity is connected to the battery mounting cavity, and the battery mounting cavity is connected to the second electrical appliance mounting cavity.

[0010] Using the aforementioned technical solution, the first heat dissipation vent and cooling fan can effectively dissipate the heat generated by the inverter inside the second electrical mounting cavity. The second heat dissipation vent on the side wall connects the first electrical mounting cavity to the outside of the casing, allowing it to promptly remove heat generated by components such as the power socket inside the first electrical mounting cavity, as well as some heat generated by the battery itself during operation. This directs airflow from the outside through the first electrical mounting cavity and the battery mounting cavity to the second electrical mounting cavity, exhibiting a trend of airflow from low to high temperature. This gradually removes heat from the power bank and reduces the mutual influence of internal heat. Simultaneously, the interconnectedness of the cavities allows for smoother airflow within the casing, forming a more efficient heat dissipation cycle. Only a small amount of cooling equipment is needed to achieve overall heat dissipation across the entire area, resulting in high heat dissipation efficiency and fast cooling speed.

[0011] Furthermore, both the front and rear partitions are provided with ventilation holes, and a gap is provided between the side wall of the battery mounting cavity and the battery body to allow airflow.

[0012] By employing the aforementioned technical solution, the perforated design of the front partition allows for smoother airflow between the first electrical appliance mounting cavity, the battery mounting cavity, and the second electrical appliance mounting cavity. Air can freely travel between the different cavities through the perforated front partition, forming a more efficient air circulation path in conjunction with the cooling fan at the bottom of the housing, the first heat dissipation vent, and the second heat dissipation vent on the side wall. The gap between the side wall of the battery mounting cavity and the battery body provides a dedicated channel for airflow. Cool air can more easily enter the battery mounting cavity, carrying away the heat generated during battery operation, while hot air can be exhausted through the gap, further enhancing the battery's heat dissipation effect, effectively reducing battery temperature, extending battery life, and ensuring the energy storage performance of the power bank.

[0013] Furthermore, a heat dissipation grille is provided at the second heat dissipation vent location, and the heat dissipation grille is recessed.

[0014] By employing the aforementioned technical solution, the heat dissipation grille effectively prevents larger external objects (such as leaves, pebbles, insects, etc.) from entering the power bank, avoiding blockage of heat dissipation channels or damage to internal electrical components. This protects components such as the inverter, power socket, and battery, improving the reliability and lifespan of the power bank. Compared to a flat grille, the concave heat dissipation grille is more effective at preventing larger objects from directly impacting the heat dissipation vents, further enhancing the protection of the internal structure. It is also more convenient to use than a protruding heat dissipation grille, avoiding the negative impact of an outward protrusion on the user experience.

[0015] Furthermore, the inverter is equipped with heat dissipation fins.

[0016] By employing the aforementioned technical solution, the heat dissipation fins can significantly increase the inverter's heat dissipation surface area. According to the principles of heat transfer, a larger heat dissipation surface area helps accelerate the conduction and convection of heat from the inverter's interior to the surrounding air. When the inverter generates heat during operation, the heat is rapidly transferred to the heat dissipation fins, and then dissipated through contact between the fins and the air. This more effectively reduces the inverter's temperature, ensuring its efficient and stable operation and extending its lifespan.

[0017] Furthermore, the upper cover is provided with a first handle and a second handle, and in the horizontal projection, the battery mounting cavity is located between the first handle and the second handle.

[0018] By adopting the aforementioned technical solution, the battery mounting cavity is located between the first and second handles within the horizontal projection, making the force-bearing point of the handles closer to the battery's center of gravity when carrying the power bank. This results in a more balanced force distribution when lifting the power bank, reducing swaying and instability caused by a shift in the center of gravity. Users can carry the power bank more easily and stably, reducing the risk of it falling or tipping over during transport and improving safety.

[0019] Furthermore, the bottom of the battery mounting cavity is provided with a wire groove baffle extending forward and backward, and the wire groove baffle is provided with a wire passage groove, the front and rear ends of which are respectively connected to the first electrical appliance mounting cavity and the second electrical appliance mounting cavity.

[0020] Using the aforementioned technical solution, the cable tray provides a dedicated routing channel for wires and cables connecting electrical components (such as inverters and power sockets) within the first and second electrical mounting cavities. This allows the wiring to pass orderly through the bottom of the battery mounting cavity, preventing haphazard wiring inside the enclosure, reducing crossings and tangles, and making the overall wiring layout more organized and clear. It facilitates wiring operations during installation and allows for easier inspection, repair, and replacement by maintenance personnel, improving production and maintenance efficiency.

The following specific embodiments can be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0028] like Figures 1 to 2As shown, this application provides an outdoor portable power supply, including a housing 1 and a battery body 2. The housing 1 is characterized by having a vertically spaced front partition 3 and a rear partition 4, which divide the space inside the housing 1 into a first electrical mounting cavity 11, a battery mounting cavity 12, and a second electrical mounting cavity 13 arranged sequentially. A power socket 5 and a display 6 are provided on the front side of the housing 1. The power socket 5 and the display 6 are partially located in the first electrical mounting cavity 11. The battery body 2 is detachably installed in the battery mounting cavity 12. An inverter 7 is installed in the second electrical mounting cavity 13.

[0029] By adopting the above technical solution, this application has the following advantages: Installing the inverter 7 in the second electrical mounting cavity 13 isolates it from the battery mounting cavity 12 where the battery body 2 is located. This prevents the heat generated by the inverter 7 during operation from directly affecting the battery, reducing the adverse effects of temperature rise on battery cycle life. Furthermore, it helps the inverter 7 dissipate heat without affecting other electrical components, thus extending battery life and ensuring the energy storage performance and overall usage time of the power bank. Moreover, the power socket 5 and display 6 are located in the first electrical mounting cavity 11, separated from the inverter 7 located in the second electrical mounting cavity 13. The heat generated by the inverter 7 will not affect the power socket 5 or the display 6, effectively maintaining the mechanical strength and insulation performance of the socket, reducing the probability of short circuits, leakage, and other safety hazards, and effectively preventing the heat from the inverter 7 from affecting the display 6, thus improving the safety of the power bank during use. Furthermore, the heaviest battery body 2 is placed in the battery mounting cavity 12 in the middle position, so that the overall center of the outdoor power bank is in the middle position, ensuring greater stability during transportation and preventing shaking and danger.

[0030] Furthermore, the bottom of the housing 1 is provided with a first heat dissipation vent 14 and a cooling fan 15. The first heat dissipation vent 14 connects the second electrical appliance mounting cavity 13 and the outside of the housing 1. The cooling fan 15 is located at a position corresponding to the first heat dissipation vent 14. The side wall of the housing 1 is provided with a second heat dissipation vent 16, which connects the second electrical appliance mounting cavity 13 and the outside of the housing 1.

[0031] By employing the aforementioned technical solution, an effective heat dissipation channel is formed by setting a first heat dissipation vent 14 and a cooling fan 15 at the bottom of the enclosure 1, and a second heat dissipation vent 16 on the side wall. The cooling fan 15 can actively extract the heat generated by the inverter 7 in the second electrical mounting cavity 13 through the first heat dissipation vent 14, and, in conjunction with the second heat dissipation vent 16 on the side wall, accelerate airflow, allowing the heat to be dissipated to the outside of the enclosure 1 more quickly. This can significantly reduce the operating temperature of the inverter 7, avoid performance degradation or malfunction due to overheating, ensure that the inverter 7 always operates within a suitable temperature range, thereby improving its working efficiency and stability, and extending the service life of the inverter 7.

[0032] Furthermore, the bottom of the housing 1 is provided with a first heat dissipation vent 14 and a cooling fan 15. The first heat dissipation vent 14 connects the second electrical appliance mounting cavity 13 and the outside of the housing 1. The cooling fan 15 is located at a position corresponding to the first heat dissipation vent 14. The side wall of the housing 1 is provided with a second heat dissipation vent 16. The second heat dissipation vent 16 connects the first electrical appliance mounting cavity 11 and the outside of the housing 1. The first electrical appliance mounting cavity 11 is connected to the battery mounting cavity 12. The battery mounting cavity 12 is connected to the second electrical appliance mounting cavity 13.

[0033] Using the aforementioned technical solution, the first heat dissipation vent 14 and the cooling fan 15 can effectively dissipate the heat generated by the inverter 7 in the second electrical mounting cavity 13. The second heat dissipation vent 16 on the side wall connects the first electrical mounting cavity 11 and the outside of the housing 1, effectively removing heat generated by components such as the power socket 5 within the first electrical mounting cavity 11, as well as some heat generated by the battery body 2 during operation. This causes the airflow to flow from the outside through the first electrical mounting cavity 11 and the battery mounting cavity 12 to the second electrical mounting cavity 13, exhibiting a trend from low temperature to high temperature. This gradually removes heat from the power bank and reduces the mutual influence of internal heat. Simultaneously, the interconnected cavities allow for smoother airflow within the housing 1, forming a more efficient heat dissipation cycle. Only a small amount of cooling equipment is needed to achieve overall heat dissipation across the entire area, resulting in high heat dissipation efficiency and fast cooling speed.

[0034] Furthermore, both the front partition 3 and the rear partition 4 are provided with ventilation holes, and a gap is provided between the side wall of the battery mounting cavity 12 and the battery body 2 to allow airflow.

[0035] Using the aforementioned technical solution, the front partition 3 is perforated, allowing for smoother airflow between the first electrical appliance mounting cavity 11, the battery mounting cavity 12, and the second electrical appliance mounting cavity 13. Air can freely travel between the different cavities through the perforated front partition 3, forming a more efficient air circulation path in conjunction with the cooling fan 15 at the bottom of the housing 1, the first heat dissipation vent 14, and the second heat dissipation vent 16 on the side wall. The gap between the side wall of the battery mounting cavity 12 and the battery body 2 provides a dedicated channel for airflow. Cold air can more easily enter the battery mounting cavity 12, carrying away the heat generated during battery operation, while hot air can be discharged through the gap, further enhancing the battery's heat dissipation effect, effectively reducing battery temperature, extending battery life, and ensuring the energy storage performance of the power bank.

[0036] Furthermore, a heat dissipation grille 17 is provided at the second heat dissipation vent 16, and the heat dissipation grille 17 is recessed.

[0037] By employing the aforementioned technical solution, the heat dissipation grille 17 effectively prevents larger external objects (such as leaves, pebbles, insects, etc.) from entering the power bank, avoiding blockage of the heat dissipation channels or damage to internal electrical components. This protects components such as the inverter 7, power socket 5, and battery, improving the reliability and lifespan of the power bank. Compared to a flat grille, the concave heat dissipation grille 17 is more effective at preventing larger objects from directly impacting the heat dissipation vents, further enhancing the protection of the internal structure. It is also more convenient to use than a protruding heat dissipation grille 17, avoiding the negative impact of an outward protrusion on the user experience.

[0038] Furthermore, the inverter 7 is provided with heat dissipation fins 71.

[0039] By employing the aforementioned technical solution, the heat dissipation fins 71 can significantly increase the heat dissipation surface area of ​​the inverter 7. According to the principle of heat transfer, a larger heat dissipation surface area helps to accelerate the conduction and convection of heat from the inside of the inverter 7 to the surrounding air. When the inverter 7 generates heat during operation, the heat is quickly transferred to the heat dissipation fins 71, and then dissipated through the contact between the fins and the air, thereby more effectively reducing the temperature of the inverter 7, ensuring its operation in a highly efficient and stable state, and extending the service life of the inverter 7.

[0040] Furthermore, the upper cover 8 is provided with a first handle 81 and a second handle 82, and the battery mounting cavity 12 is located between the first handle 81 and the second handle 82 in the horizontal projection.

[0041] By adopting the aforementioned technical solution, the battery mounting cavity 12 is located between the first handle 81 and the second handle 82 within the horizontal projection, making the force-bearing point of the handle closer to the battery's center of gravity when carrying the power bank. This results in a more balanced force distribution when lifting the power bank, reducing swaying and instability caused by center of gravity shift. Users can carry the power bank more easily and stably, reducing the risk of it falling or tipping over during transport and improving safety.

[0042] Furthermore, the bottom of the battery mounting cavity 12 is provided with a wire groove baffle 9 extending from front to back, and the wire groove baffle 9 is provided with a wire passage groove 91, the front and rear ends of the wire passage groove 91 being connected to the first electrical appliance mounting cavity 11 and the second electrical appliance mounting cavity 13 respectively.

[0043] Using the aforementioned technical solution, the wiring trough 91 provides a dedicated routing channel for the wires and cables connecting the electrical components (such as the inverter 7, power socket 5, etc.) within the first electrical mounting cavity 11 and the second electrical mounting cavity 13. This allows the wiring to pass through the bottom of the battery mounting cavity 12 in an orderly manner, avoiding haphazard wiring inside the housing 1, reducing crossings and tangles between wires, and making the overall wiring layout more organized and clear. This facilitates wiring operations during installation by personnel assembling the power bank and also makes it easier for maintenance personnel to inspect, repair, and replace the wiring later, improving production and maintenance efficiency.
