Description

Technical Field

[0001] This utility model relates to the field of outdoor battery technology, specifically to an outdoor battery pack suitable for high-temperature environments. Background Technology

[0002] Outdoor power supplies, also known as portable energy storage power supplies, are similar to mobile power stations outdoors. Their main feature is their comprehensive charging interface configuration, allowing users to power commonly used outdoor devices such as mobile terminals, cooking appliances, projectors, outdoor refrigerators, and drones. Some can even be used as power sources for electric vehicles. Generally, outdoor power supplies need to be placed on the ground outdoors. However, in hot summer weather, air temperatures can reach around 40°C, and ground temperatures can reach around 70°C. Using outdoor power supplies in such high-temperature environments already increases the heat dissipation pressure during operation, leading to safety hazards due to rapid temperature rise. If outdoor power supplies are still placed directly on the ground, the high temperature of the ground directly heats the power supply, causing it to continuously absorb heat from the ground in addition to the heat generated during operation, further increasing the heat dissipation pressure and safety risks.

[0003] Currently, outdoor power supplies with heat dissipation functions have emerged, such as the outdoor battery heat dissipation device disclosed in patent CN118231862A. This device features a vertically movable floating frame around the battery, with an air outlet on the side facing the battery. A fan directs airflow into the inner cavity of the floating frame, ultimately blowing the air onto the battery through the outlet. The floating frame's vertical movement increases the coverage of the airflow area on the battery's outer perimeter, thereby cooling the battery. While this prior art promotes battery heat dissipation by blowing air onto the battery, its effectiveness is limited in high-temperature environments (around 40°C). The cooling rate may not match the heating rate of the ground at around 70°C, failing to effectively suppress battery overheating and posing safety hazards. This makes the outdoor battery unsuitable for high-temperature outdoor environments. Utility Model Content

[0004] The purpose of this invention is to provide an outdoor battery pack suitable for high-temperature environments, solving the problem that outdoor battery packs cannot adapt to high-temperature environments. By raising the battery body with a heat dissipation bracket and only having a small contact area with the ground through vertical support legs, the heat transfer efficiency from the ground to the heat dissipation bracket and the battery body is effectively reduced, the temperature rise of the battery body is suppressed, the safety risks during use are reduced, and the battery body is adapted to high-temperature environments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an outdoor battery pack suitable for high-temperature environments, characterized in that it includes a battery body and a heat dissipation bracket, the heat dissipation bracket including a frame, legs and rods, the frame being arranged horizontally and fitted around the battery body, a plurality of legs extending downward from the frame, the legs being arranged in a one-to-one correspondence with the rods, the rods extending horizontally from the legs toward the inside of the frame, the height of the rods being lower than the frame and higher than the bottom of the legs, the battery body being placed inside the frame from top to bottom, and the plurality of rods jointly supporting the battery body so that the battery body is suspended in the air.

[0006] In one embodiment, a heat insulation pad is provided between the support rod and the battery body to block heat transfer between the support rod and the battery body.

[0007] In one embodiment, a heat insulation pad is provided above the support rod. The area of ​​the heat insulation pad is larger than the area of ​​the lower side of the battery body. Multiple support rods jointly support the heat insulation pad so that the heat insulation pad covers the battery body from bottom to top.

[0008] In one embodiment, the support rod and the support leg are detachably connected, and the thermal conductivity of the support rod is lower than that of the support leg.

[0009] In one embodiment, the heat insulation pad has a heat insulation cavity filled with cold water to make the heat insulation pad heat-insulating and shock-absorbing.

[0010] In one embodiment, the heat insulation pad is provided with a strap corresponding to the support rod, so that the heat insulation pad can be detachably connected to the support rod via the strap.

[0011] In one embodiment, at least two of the support rods have a first flow cavity, the support leg has a second flow cavity, and the frame has a third flow cavity. The second flow cavity connects the first flow cavity and the third flow cavity. The support rod is provided with a water outlet that connects to the first flow cavity. The heat insulation pad has a connector that connects to the water outlet. The heat insulation cavity is connected to the first flow cavity through the connector. The heat dissipation bracket is provided with a circulating water pump so that cold water in the heat insulation pad flows through the first flow cavity, the second flow cavity, and the third flow cavity for heat dissipation.

[0012] The advantages of this application compared to the prior art are: In this embodiment, the battery body is raised by a heat dissipation bracket, and only a small area of ​​contact with the ground is made through vertical support legs. This effectively reduces the heat transfer efficiency from the ground to the heat dissipation bracket and the battery body, suppresses the temperature rise of the battery body, reduces safety risks during use, and enables the battery body to adapt to high-temperature environments.

[0019] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.

[0020] Please refer to Figure 1 This illustration shows an outdoor battery pack suitable for high-temperature environments according to an embodiment of this application, including a battery body 100 and a heat dissipation bracket 200. The heat dissipation bracket 200 includes a frame 210, legs 220, and support rods 230. The frame 210 is arranged horizontally and fits around the battery body 100. Multiple legs 220 extend downward from the frame 210. Each leg 220 is correspondingly arranged with a support rod 230. The support rod 230 extends horizontally from the legs 220 toward the inside of the frame 210. The height of the support rod 230 is lower than the frame 210 and higher than the bottom of the legs 220. The battery body 100 is placed inside the frame 210 from top to bottom. Multiple support rods 230 jointly support the battery body 100, so that the battery body 100 is suspended in the air.

[0021] In this embodiment of the application, the outdoor battery pack includes a battery body 100 and a heat dissipation bracket 200. The battery body 100 is placed on the heat dissipation bracket 200, which supports the battery body 100. In use, the heat dissipation bracket 200 is placed on the ground, and the battery body 100 is raised by the heat dissipation bracket 200 to prevent the battery body 100 from directly contacting the high-temperature ground (which can reach about 70°C in high-temperature environments). This prevents the high-temperature ground from directly transferring heat to the battery body 100, thereby suppressing the temperature rise of the battery body 100. Specifically, the heat dissipation bracket 200 includes a frame 210, legs 220, and support rods 230. The frame 210 is arranged horizontally, allowing the space enclosed by the frame 210 to be vertically open, enabling the battery body 100 to enter from top to bottom. The battery body 100 is surrounded by the frame 210, enclosing it within the heat dissipation bracket 200. Multiple legs 220 are connected to the frame 210 and extend downwards from it, contacting the ground and supporting the frame 210. Support rods 230 are connected to the legs 220 and extend horizontally inwards from them toward the inside of the frame 210. Each leg 220 has a support rod 230, resulting in multiple horizontally extending support rods 230 within the inner area of ​​the frame 210. Please refer to... Figure 2 A handle 110 may be provided on the upper side of the battery body 100 so that the user can lift the battery body 100.

[0022] It should be noted that the number of supports 220 is three or more, and the supports 220 are not arranged in the same direction to ensure that the heat dissipation bracket 200 is placed stably on the ground. Preferably, the frame 210 is rectangular to fit the rectangular outer contour of the battery body 100. The frame 210 and the battery body 100 can be spaced a certain distance apart, such as 0.5-3 cm. Preferably, there are four supports 220. There are two specific implementation methods for the placement of the supports 220: one implementation method is that the supports 220 are positioned one-to-one with the four corner positions of the frame 210; the other implementation method is that the supports 220 are positioned one-to-one with the middle parts of the four straight edges of the frame 210. This embodiment prefers the second implementation method. Specifically, the support legs 220 are located at the middle of each straight side of the rectangular frame 210. It is further preferred that each support rod 230 is perpendicular to the straight side of the frame 210 on its own side, so that there are two pairs of support rods 230 facing each other. One pair of support rods 230 extends in the left-right direction, and the other pair of support rods 230 extends in the front-back direction. A total of four support rods 230 distributed around the circumference of the frame 210 jointly support the battery body 100.

[0023] In this embodiment, the height of the support rod 230 is lower than that of the frame 210 and higher than that of the support leg 220. Thus, the support rod 230 is also in a raised state and does not directly contact the ground. The battery body 100 is placed from top to bottom in the space enclosed by the frame 210 and is supported by the support rod 230, thereby raising the battery body 100. The battery body 100 can be partially higher than the frame 210. The key is that the lower part of the battery body 100 extends into the space enclosed by the frame 210. The support rod 230 supports the battery body 100, and the frame 210 blocks the side of the battery body 100. The frame 210 keeps the battery body 100 in the heat dissipation bracket 200 to prevent the battery body 100 from detaching from the heat dissipation bracket 200. The battery body 100 can only be detached from the heat dissipation bracket 200 when the user lifts it upwards. The support rod 230 elevates the battery body 100. Neither the support rod 230 nor the battery body 100 directly contacts the ground, thereby preventing the ground from directly transferring heat to the support rod 230 and the battery body 100, thus suppressing the temperature rise of the battery body 100. In this embodiment, the heat dissipation bracket 200 directly contacts the ground only through the support legs 220. The support legs 220 extend vertically, and the lower side area of ​​the support legs 220 is small. Therefore, the contact area between the support legs 220 and the ground is small, thereby reducing the efficiency of the ground in transferring heat to the heat dissipation bracket 200.

[0024] Therefore, in this embodiment of the application, the battery body 100 is raised by the heat dissipation bracket 200 and only has a small contact area with the ground through the vertical support legs 220, thereby effectively reducing the heat transfer efficiency from the ground to the heat dissipation bracket 200 and the battery body 100, suppressing the temperature rise of the battery body 100, reducing the safety risks during use, and making the battery body 100 adaptable to high temperature environments.

[0025] Preferably, please refer to Figure 3 In one embodiment of this application, a heat insulation pad 240 is provided between the support rod 230 and the battery body 100 to block heat transfer between the support rod 230 and the battery body 100. In some embodiments of this application, the heat dissipation bracket 200 is made of metal to ensure its structural strength. However, metal has high thermal conductivity, and heat from the ground is transferred to the heat dissipation bracket 200, causing the support rod 230 to reach a high temperature. In this embodiment, the heat insulation pad 240 between the support rod 230 and the battery body 100 can block heat transfer between them. Therefore, even if the support rod 230 reaches a high temperature, the heat transfer from the support rod 230 to the battery body 100 can be reduced, thereby suppressing the temperature rise of the battery body 100 and enabling it to adapt to high-temperature environments. The heat insulation pad 240 can be made of materials such as cotton, bamboo, hemp, or silicone, or it can be a bag-shaped pad filled with a heat insulation medium.

[0026] Preferably, please refer to Figure 4 In one embodiment of this application, a heat insulation pad 240 is provided above the support rod 230. The area of ​​the heat insulation pad 240 is larger than the area of ​​the lower side of the battery body 100. Multiple support rods 230 jointly support the heat insulation pad 240 so that the heat insulation pad 240 shields the battery body 100 from bottom to top. In this embodiment, the heat insulation pad 240 is disposed between the battery body 100 and the support rod 230, and the area of ​​the heat insulation pad 240 is larger than the area of ​​the lower side of the battery. The battery body 100 is generally rectangular in shape, so that the vertical projection of the battery body 100 falls within the range of the heat insulation pad 240, allowing the heat insulation pad 240 to shield the battery body 100 from bottom to top, isolating the battery body 100 from the high-temperature ground, thereby isolating the upward heat radiation from the high-temperature ground from the battery body 100, further reducing the "heating" effect of the high-temperature ground on the battery body 100, and thus further suppressing the temperature rise of the battery body 100.

[0027] Preferably, in one embodiment of this application, the support rod 230 and the support leg 220 are detachably connected, and the thermal conductivity of the support rod 230 is lower than that of the support leg 220. In this embodiment, the support rod 230 and the support leg 220 of the heat dissipation bracket 200 are detachably connected. The support rod 230 is a component that supports the battery body 100. Therefore, in this embodiment, the support leg 220 and the frame 210 can be made of metal, which facilitates the welding connection or integral molding of the support leg 220 and the frame 210 and can improve the structural strength of the heat dissipation bracket 200. The support rod 230 can be made of plastic and connected to the support leg 220 by means of plug-in or threaded connection. In this way, the thermal conductivity of the support rod 230 is lower than that of the support leg 220. Even if the support leg 220, which is in direct contact with the ground, absorbs more heat, the heat absorbed by the support rod 230 from the support leg 220 can be reduced (compared to the case where the support rod 230 is also made of metal), thereby further reducing the transfer of heat to the battery body 100 and further suppressing the temperature rise of the battery body 100.

[0028] Preferably, in one embodiment of this application, the heat insulation pad 240 has a heat insulation cavity 340 filled with cold water to provide heat insulation and shock absorption. In this embodiment, the heat insulation pad 240 is specifically a bagged pad with an inner cavity. It is generally flat, but has an internal heat insulation cavity 340 for filling with cold water, which acts as a heat insulation medium. During use, the heat insulation pad 240 shields the battery body 100 from bottom to top. The heat insulation pad 240 is relatively close to the hot ground, and its function is to block heat from below the battery body 100. Therefore, the heat insulation pad 240 itself continuously absorbs heat. In this embodiment, the heat insulation cavity 340 inside the heat insulation pad 240 is filled with cold water. Cold water has a large specific heat capacity, and its temperature change is small when absorbing the same amount of heat. Therefore, while the heat insulation pad 240 continuously absorbs heat through cold water, its own temperature rise is small, which reduces the impact on the battery body 100 and further suppresses the temperature rise of the battery body 100, making the battery body 100 adapt to the high temperature environment.

[0029] Preferably, in one embodiment of this application, the heat insulation pad 240 is provided with a strap (not shown in the figure) corresponding to the support rod 230, so that the heat insulation pad 240 is detachably connected to the support rod 230 through the strap. Thus, in actual use, when the heat insulation pad 240 absorbs too much heat, resulting in a high temperature, the battery body 100 can be lifted to remove it from the heat dissipation bracket 200, the strap can be loosened, the heat insulation pad 240 can be removed, and after cooling, it can be reinstalled on the heat dissipation bracket 200. For example, in outdoor conditions, the heat insulation pad 240 can be immersed in a nearby river for a period of time to allow it to cool down sufficiently and quickly.

[0030] Preferably, please refer to Figure 5 , Figure 6 In one embodiment of this application, at least two of the support rods 230 have a first flow cavity 310, the support leg 220 has a second flow cavity 320, and the frame 210 has a third flow cavity 330. The second flow cavity 320 connects the first flow cavity 310 and the third flow cavity 330. The support rod 230 is provided with a water outlet 231 that connects to the first flow cavity 310. The heat insulation pad 240 has a connector 241 that connects to the water outlet 231. The heat insulation cavity 340 connects to the first flow cavity 310 through the connector 241. The heat dissipation bracket 200 is provided with a circulating water pump (not shown in the figure) to allow cold water in the heat insulation pad 240 to flow through the first flow cavity 310, the second flow cavity 320, and the third flow cavity 330 for heat dissipation. In this embodiment, the heat insulation pad 240 is connected to the water outlet 231 on the support rod 230 through the connector 241, so that the heat insulation cavity 340 in the heat insulation pad 240 is connected to the first flow cavity 310 in at least two support rods 230, and the second flow cavity 320 in the support leg 220 connects the first flow cavity 310 in the support rod 230 to the third flow cavity 330 in the frame 210. Therefore, the heat insulation cavity 340, the first flow cavity 310, the second flow cavity 320 and the third flow cavity 330 are connected to form a cold water flow loop. When the temperature of the cold water in the insulation cavity 340 is low, the circulating water pump is not started. Since the height of the insulation cavity 340 is lower than that of the frame 210, the cold water mainly remains in the insulation cavity 340, with a small portion possibly flowing into the first flow cavity 310 of the support rod 230. At this time, the cold water absorbs the heat radiated outward from the high-temperature ground. When the temperature of the cold water in the insulation cavity 340 becomes higher, the circulating water pump is started, drawing the cold water upward into the third flow cavity 330 of the frame 210. This temporarily removes the cold water from the high-temperature ground, reducing heat absorption and allowing the cold water to cool down to some extent during the flow. The circulating water pump is run for a certain period of time, allowing the cold water to circulate a certain number of times in the entire flow loop. Once the temperature of the cold water has decreased to a certain extent, the circulating water pump is turned off, allowing the cold water to flow back into the insulation cavity 340 under the influence of gravity.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
