Description

Technical Field

[0001] The present invention relates to the technical field of energy storage power supplies, and specifically to an energy storage power supply. Background Art

[0002] As an outdoor emergency power supply, the energy storage power supply has the characteristics of light weight, large capacity, and high power, and is widely used in electronic devices. A battery pack for power supply is arranged inside the energy storage power supply. When the battery pack powers the electronic device, the battery pack generates heat, causing the temperature inside the energy storage power supply to rise. Considering that there are multiple electronic components inside the energy storage power supply, and most of the electronic components have an operating temperature range. Once this operating temperature range is exceeded, it means that the electronic components will fail, their performance will decrease, or they will even be damaged. Even if the temperature does not exceed the operating temperature range, when there are large temperature fluctuations, it will also affect the normal use of the electronic components. Therefore, at present, most energy storage power supplies are provided with a heat dissipation structure.

[0003] Currently, the heat dissipation structure of the energy storage power supply is usually a heat dissipation window arranged on the housing of the energy storage power supply. The heat dissipation windows are arranged on two opposite side surfaces of the housing. When the energy storage power supply is in use, there is a temperature difference between the energy storage power supply and the external air. Then, the cold air outside enters the inside of the energy storage power supply through the heat dissipation window on one side of the housing, and then flows out through the heat dissipation window on the other side, thereby taking out the heat inside the energy storage power supply to achieve the purpose of heat dissipation and temperature reduction. Generally speaking, in order to ensure the heat dissipation effect, a heat dissipation fan is arranged inside the energy storage power supply to forcibly accelerate the air flow velocity by using the heat dissipation fan, which also increases the cost of the heat dissipation structure. Therefore, in order to minimize the cost of the heat dissipation structure as much as possible, the current heat dissipation windows are mostly set as a fixed-open structure, and there is no need to additionally set an opening and closing structure for the heat dissipation windows. However, the energy storage power supply with fixed-open heat dissipation windows will have the phenomenon of water and dust ingress during outdoor use, which greatly affects the normal use of the energy storage power supply. Summary of the Invention

[0004] The present invention aims to provide an energy storage power supply to solve the problem that the existing energy storage power supply is prone to water and dust ingress.

[0005] The basic solution provided by the present invention is: an energy storage power supply, including a housing, a battery pack and a heat dissipation fan are arranged inside the housing, a heat dissipation window is arranged on the housing, the heat dissipation window includes an air inlet part and an air outlet part, and a baffle is arranged on the heat dissipation window;

[0006] Wherein, the baffle includes a second panel that can be opened inward and multiple first panels that are linked and can be opened outward; a return component for driving the second panel back to the initial position is also arranged inside the housing.

[0007] Explanation: In this solution, "outward" refers to the direction towards the outside of the housing, and "inward" refers to the direction towards the inside of the housing.

[0008] The beneficial effects of the basic solution are as follows: Although in the design of existing heat dissipation windows, fixed outward-opening baffles are mostly used as a blocking structure, which can prevent external substances such as rainwater and dust falling from above from entering the shell, since the baffle is fixed open, when heat dissipation is not required, the heat dissipation window is also in an open state, and some external substances can still enter the inside of the shell through the heat dissipation window, thus affecting the normal use of the energy storage power supply. Therefore, in this solution, the existing baffle is divided into a first baffle and a second baffle. The first baffle is designed to be able to open freely outward. When heat dissipation is required, the heat dissipation fan starts. At the moment when the heat dissipation fan starts, the first baffle at the air outlet part will open outward by a small angle under the action of the heat dissipation fan, and part of the air in the shell will flow out, and a negative pressure will appear in the shell. Since multiple first baffles are linked to open outward, after the first baffle at the air outlet part opens outward, the first baffle at the air inlet part will also open outward by a small angle.

[0009] However, as more and more air flows out of the shell, the negative pressure in the shell becomes greater and greater. Then, the first baffle at the air inlet part is forced to swing reversely under the action of the negative pressure, so as to return to the initial position, which in turn drives the first baffle at the air outlet part to also swing back to the initial position, resulting in the heat dissipation window being unable to achieve normal heat dissipation.

[0010] Therefore, in this application, a second baffle is also provided. At the moment when the heat dissipation fan is turned on and a negative pressure appears in the shell, the second baffle opens inward under the action of the negative pressure, and external air smoothly enters the shell from the opened second baffle and then flows out from the air outlet part of the heat dissipation window. Thus, the air in the shell can flow smoothly, and the first baffle is pushed to a larger angle under the action of the flowing air, so that external air can also smoothly enter the shell from the air inlet part.

[0011] When the air can smoothly enter the shell from the air inlet part, under the action of the return component, the second baffle will overcome the air thrust and return to the initial position, achieving the effect of dust and water prevention.

[0012] When heat dissipation is not required, the heat dissipation fan stops working, and then the first baffle returns to the initial position to seal the shell, preventing external impurities from entering the shell and strengthening the dust and water prevention effect.

[0013] In this solution, the opening of the first baffle is achieved by the cooperation of a second baffle that can be opened inward and a return component. Compared with the prior art, the original baffle is divided into the design of the first baffle and the second baffle, without adding any extra heat dissipation structure. Moreover, during the whole process, the existing cooling fan is used as the driving source, without setting an additional driving source. That is, in the case of adding the function of automatic opening and closing of the heat dissipation window, only a simple return component is added. Compared with solutions using some automatic controllers, etc., the manufacturing cost is greatly reduced.

[0014] Furthermore, the upper end of the first baffle is hinged to the inner wall of the housing. Beneficial effect: In this solution, after the upper end of the first baffle is hinged to the inside of the housing, when the cooling fan is not working, the first baffle will return to its initial position under its own gravity, thus closing the housing. The structure is simple and there is no need to set an additional return structure, further reducing the manufacturing cost.

[0015] Furthermore, the return component is a torsion spring. Beneficial effect: As a commonly used part, the torsion spring has a low cost and is easy to obtain.

[0016] Furthermore, a stop block is provided between the upper end of the second baffle and the lower end of the adjacent first baffle. Beneficial effect: Considering that the second baffle will swing outward under the action of the return component and may push the adjacent first baffle to swing outward, in this solution, the setting of the stop block can limit the amplitude of the outward swing of the second baffle, thus preventing the outward-swinging second baffle from interfering with the first baffle, and ensuring the sealing effect of the housing when heat dissipation is not required.

[0017] Furthermore, multiple said first baffles are opened or closed simultaneously. Beneficial effect: In this solution, the method of setting multiple first baffles to be opened or closed simultaneously can avoid the problem of whistling when multiple first baffles are opened or closed at different times, thus improving the user experience.

[0018] Furthermore, a connection structure is also provided on the housing. The connection structure includes an installation groove provided on the inner wall of the housing. A connecting rod is provided in the installation groove. Multiple connecting support rods corresponding to the first baffles are provided on the connecting rod. The connecting support rods are hinged to the side wall of the first railing. Beneficial effect: In this solution, the connecting support rods are provided to realize the connection between the connecting rod and multiple first baffles. When the first baffle at the air inlet part swings, the first baffle at the air outlet part can be driven to swing together through the connecting rod, that is, multiple first baffles can be opened simultaneously. The structure is simple. And the connection structure in this solution can also make the rotation angles of multiple first baffles the same, thus avoiding the problem of noise caused by different rotation angles of different first baffles.

[0019] Further, connection structures are provided on both opposite sides of the housing. Beneficial effect: In this solution, the provision of connection structures on both sides can ensure that both sides of the first shutter swing by the same angle, thereby avoiding the problem that the first shutter cannot swing normally due to different swing angles on both sides of the first shutter, and thus ensuring the smooth opening of the heat dissipation window.

[0020] Further, the battery pack assembly is arranged close to the air inlet part. Beneficial effect: In this solution, the way of arranging the battery pack assembly close to the air inlet part enables the external cold air to come into contact with the battery pack for the first time. Compared with the way of arranging the battery pack assembly at other positions, the earlier the cold air comes into contact with the battery pack, the more heat it can take away, thereby improving the heat dissipation efficiency.

[0021] Further, a partition and a ventilation duct are arranged in the housing along the length direction of the housing. The partition is located between the air inlet part and the air outlet part, and the ventilation duct is arranged away from the heat dissipation window. Beneficial effect: In this solution, the arrangement of the partition divides the air duct inside the housing into a U-shaped air duct, which can guide the air flowing in the housing, realize the unidirectional flow of air in the housing, enable the air in the housing to flow out smoothly from the outlet part far from the heat dissipation window, extend the flow path of the air in the housing, and can fully take away the heat in the housing, improving the heat dissipation effect.

[0022] Further, two adjacent first shutters are overlapped, and a fitting structure is arranged on the overlapping part. Beneficial effect: In this solution, the provision of the fitting structure can ensure the sealing between adjacent first shutters when heat dissipation is not required, thereby ensuring the sealing of the housing and enhancing the dust and water protection effects.

[0023] Further, the fitting structure includes a first fitting part arranged at the upper end of the first shutter and a second fitting part arranged at the lower end of the first shutter. Beneficial effect: In this solution, the fitting part is composed of the first fitting part and the second fitting part, and the structure is simple. Description of the Drawings

[0028] The following is a further detailed description through specific embodiments:

[0029] The reference numerals in the accompanying drawings of the specification include: housing 1, battery pack assembly 11, cooling fan 12, cooling window 2, first baffle 21, second baffle 22, return assembly 23, connecting rod 231, connecting support rod 232, stop block 24, and partition 3.

[0030] The embodiment is basically as shown in the accompanying drawings Figure 1 and Figure 2 as follows: An energy storage power supply includes a housing 1. Inside the housing 1, a battery pack assembly 11 and a cooling fan 12 are provided. The housing 1 is provided with a cooling window 2. The cooling window 2 includes an air inlet part at the upper end and an air outlet part at the lower end. The air inlet part and the air outlet part are located on the same side of the housing 1. The battery pack assembly 11 is arranged close to the air inlet part, that is, the battery pack assembly 11 is located at the lower part of the housing 1. Inside the housing 1, a partition 3 and a ventilation duct are arranged along the length direction of the housing 1. The ventilation duct is arranged away from the cooling window 2. Specifically, one end of the partition 3 is located between the air inlet part and the air outlet part and is connected to the inside of the housing 1. A ventilation duct is arranged between the other end of the partition 3 and the inner wall of the housing 1 and is provided with a vertical air guiding plate. In other embodiments, a ventilation duct can also be formed by setting through holes at one end of the partition away from the cooling window 2.

[0031] The cooling window 2 is provided with a baffle. The baffle includes a second baffle 2 that can be opened inward and multiple first baffles 21 that are linked and can be opened outward. In this embodiment, multiple first baffles are set to be opened or closed simultaneously. Specifically, the second baffle 22 is located at the bottom of the air inlet part. The lower end of the second baffle 22 is hinged to the inner wall of the housing 1, and a return assembly 23 for driving the second stop block 24 back to the initial position is arranged on the side of the second baffle 22 facing the inside of the housing 1. As shown in Figure 4 the figure, the return assembly 23 is a torsion spring. In other embodiments, the return assembly 23 can also be a tension spring or other components.

[0032] The upper end of the first baffle 21 is hinged to the inner wall of the housing 1. The housing 1 is also provided with a connection structure. The connection structure includes a mounting groove arranged on the inner wall of the housing 1. A connecting rod 231 is arranged in the mounting groove. Multiple connecting support rods 232 corresponding to the first baffles 21 are arranged on the connecting rod 231. The connecting support rods 232 are hinged to the side wall of the first baffle 21 to achieve the purpose of opening multiple first baffles 21 simultaneously, as shown in Figure 3 the figure. Preferably, connection structures are arranged on two opposite inner walls of the housing 1. The second baffle 22 is located at the bottom of the housing 1. A stop block 24 is arranged between the lower end of the lowermost first baffle 21 and the upper end of the second baffle 22.

[0033] Two adjacent first railing plates 21 are overlapped, and a fitting structure is provided on the overlapping part. The fitting structure includes a first fitting portion provided at the upper end of the first railing plate 21 and a second fitting portion provided at the lower end of the first railing plate 21. As Figure 3 shown, the first fitting portion is provided with a concave portion, and the second fitting portion is provided with a convex portion that fits with the concave portion.

[0034] The specific implementation process is as follows: Figure 2 The dotted arrow in the figure is the air flow direction inside the housing. In the initial state, the energy storage power supply does not work, that is, both the battery pack assembly 11 and the cooling fan 12 are not started, the first railing plate 21 and the second railing plate 22 are both in the vertical state, and the heat dissipation window 2 of the housing 1 is in the closed state.

[0035] When the energy storage power supply works, the cooling fan 12 starts. At the moment when the cooling fan 12 starts, a part of the air inside the housing 1 is forced by the cooling fan 12 to the air outlet part, and the first railing plate 21 at the air outlet part is pushed open by a small angle, and the air flows out of the housing 1. A negative pressure appears inside the housing 1. Under the action of the negative pressure, the second railing plate 22 at the lower part of the housing 1 is pushed and overcomes the acting force of the return component 23, and opens towards the inside of the housing 1. Then, a part of the heat dissipation window 2 at the second railing plate 22 is opened, and the external air enters the housing 1 from the second railing plate 22. Then, under the guiding action of the partition plate 3, it flows through the ventilation duct to the upper part of the partition plate 3 and finally flows out from the air outlet part.

[0036] As more and more air flows out of the housing 1 at the same time, the swing angle of the first railing plate 21 becomes larger and larger under the push of the air. Then, more and more air enters through the air outlet part. At this time, the second railing plate 22 returns to the position where it abuts against the stopper 24 under the push of the return component 23.

[0037] When the energy storage power supply does not work, at this time, the cooling fan 12 stops working, and the first railing plate 21 swings downward under its own gravity and returns to the initial position, re-closing the heat dissipation window 2 to achieve the effect of dust and water prevention.
