Description

Technical Field

[0001] This invention relates to the field of battery heat dissipation technology, and more specifically, to a battery cooling device, an unmanned equipment charging station, and an unmanned equipment system. Background Technology

[0002] In related technologies, batteries for unmanned equipment (such as drones, unmanned vehicles, robots, etc.) use air cooling or water cooling to accelerate heat dissipation. However, air cooling is limited by ambient temperature and often cannot dissipate heat effectively in hot summers. Water cooling usually requires immersing the battery in water, but since most battery components cannot come into contact with water, only a part of the battery can be immersed in water, which means that the other part of the battery still cannot be effectively cooled.

[0003] Another related technology aims to improve the heat dissipation of batteries by atomizing water and combining it with airflow to remove the heat from the battery. Since water evaporation removes a large amount of heat, the water mist will quickly evaporate and vaporize on the high-temperature battery surface. At the same time, the airflow brought by the fan further accelerates the evaporation rate of the water. By combining the rapid vaporization of water mist with airflow, the heat absorption efficiency can be maximized, allowing the battery to cool down quickly in a short time.

[0004] However, the battery cooling device that uses water mist to cool the battery provided by the related technology has an unstable mist output, which can easily lead to unstable cooling effect. Summary of the Invention

[0005] The purpose of this invention is to provide a battery cooling device, an unmanned equipment charging station, and an unmanned equipment system. The battery cooling device can be used in the unmanned equipment charging station of the unmanned equipment system. The battery cooling device can maintain a stable amount of mist output, thereby ensuring the stability of the cooled battery.

[0006] The embodiments of the present invention are implemented as follows:

[0007] In a first aspect, the present invention provides a battery cooling device, comprising:

[0008] A liquid storage tank, which is equipped with a liquid storage chamber and a liquid outlet, with the liquid storage chamber and the liquid outlet connected together;

[0009] The atomizing box is located at the bottom of the liquid storage tank and has an atomizing chamber.

[0010] Atomizer, located in an atomization chamber, is used to atomize the liquid within the atomization chamber into droplets for cooling the battery; and,

[0011] An opening and closing assembly is located at the liquid outlet and is used to open or close the liquid outlet. When the opening and closing assembly opens the liquid outlet, the liquid in the storage chamber enters the atomizing chamber through the liquid outlet. When the opening and closing assembly closes the liquid outlet, the liquid in the storage chamber does not pass through the liquid outlet.

[0012] In an optional embodiment, the opening and closing assembly includes a float and a valve. The valve is located at the liquid outlet, and the float is rotatably disposed within the atomizing chamber and configured to open the liquid outlet via the valve.

[0013] When the liquid level in the atomizing chamber reaches the first preset liquid level, the float rotates under its own weight, causing the valve to open the liquid outlet; when the liquid level in the atomizing chamber reaches the second preset liquid level, the float resets under the action of buoyancy, and the valve closes the liquid outlet; the second preset liquid level is higher than the first preset liquid level.

[0014] In an optional embodiment, the valve includes a valve body and a resilient element. The valve body is movably disposed at the outlet for opening or closing the outlet, and the resilient element is configured to elastically engage with the valve body. A float is driven by the valve body.

[0015] When the liquid level in the atomizing chamber reaches the first preset liquid level, the float rotates under its own weight, pushes the valve body and overcomes the elastic force of the elastic element to open the liquid outlet;

[0016] When the liquid level in the atomizing chamber reaches the second preset liquid level, the float resets under the action of buoyancy, and the valve body resets to the closed liquid outlet under the elastic force of the elastic element.

[0017] In an optional embodiment, the float includes a float body and a pusher connected to the end of the float body. The float body is rotatably disposed in the atomizing chamber, and the pusher is in a transmission cooperation with the valve body.

[0018] When the liquid level in the atomization chamber reaches the first preset liquid level, the float body rotates under its own weight, which drives the pusher to move, thereby pushing the valve body and overcoming the elastic force of the elastic element to open the liquid outlet.

The fixing member is connected to at least one of the two support seats and prevents the rotating shaft from disengaging from the grooves.

[0022] In an optional embodiment, the opening and closing assembly includes a float rotatably disposed within the atomizing chamber. The float has a first end and a second end that are relatively distributed, and the first end is capable of opening or closing the liquid outlet; wherein,

[0023] The distance from the second end to the axis of rotation of the float is less than the distance from the first end to the axis of rotation of the float;

[0024] When the liquid level in the atomizing chamber reaches the first preset liquid level, the float rotates under its own weight and opens the liquid outlet at the first end.

[0025] When the liquid level in the atomizing chamber reaches the second preset liquid level, the float resets under the action of buoyancy and closes the liquid outlet at the first end.

[0026] The second preset liquid level is higher than the first preset liquid level.

[0027] In an optional embodiment, the battery cooling device further includes a mist channel and a mist outlet communicating with the mist channel. The mist channel is also communicating with the atomization chamber so that the mist droplets in the atomization chamber are guided through the mist channel and then output from the mist outlet.

[0028] In an optional embodiment, the mist channel includes a first channel and a second channel that are interconnected. The end of the first channel away from the second channel is connected to the atomizing chamber, and the second channel is connected to the mist outlet. The second channel is an flared channel, and the inner diameter of the end of the second channel closer to the first channel is smaller than the inner diameter of the second channel away from the first channel.

[0029] In an optional implementation, the inner diameter of the second channel gradually increases from the end closer to the first channel to the end farther away from the first channel.

[0030] In an optional implementation, the inner diameter of the first channel is less than or equal to the inner diameter of the end of the second channel that connects to the first channel.

[0031] In an optional implementation, a flow divider is provided in the second channel to disperse the mist that enters the second channel from the first channel.

[0032] In an optional implementation, the mist channel is located in the liquid storage tank.

[0033] In an optional embodiment, the liquid storage tank is provided with an airflow channel, which is connected to the mist outlet;

[0034] The battery cooling device also includes a fan located in the airflow channel to blow the mist droplets that enter the airflow channel out of the airflow channel.

[0035] In an optional embodiment, the battery cooling device further includes a rectifier disposed on the air outlet side of the fan, which is used to convert the rotating airflow blown out by the fan into a straight airflow.

[0039] In an optional embodiment, the battery connection assembly has a receiving space for housing the battery, and when no battery is installed in the receiving space, the liquid storage tank and the atomizing box can be installed in the receiving space.

[0040] In an optional embodiment, the battery connection assembly includes a guide member detachably disposed on the side wall of the receiving space and the guide member is used for sliding engagement with the battery; when the guide member is removed from the side wall of the receiving space and no battery is disposed in the receiving space, the liquid storage tank and the atomizing box can be disposed in the receiving space.

[0041] In an optional embodiment, the battery connection assembly further includes a connector, two guides, two supports, two first side plates, and two second side plates. The two supports are connected by the connector. The two first side plates are connected to one of the supports and are spaced apart. The two second side plates are connected to the other support and are spaced apart. A receiving space is formed between the two first side plates and the two second side plates. One of the first side plates is detachably connected to one of the guides, and one of the second side plates is detachably connected to the other guide.

[0042] Secondly, the present invention provides an unmanned equipment charging station, which includes a battery, a charging device and the aforementioned battery cooling device.

[0043] Thirdly, the present invention provides an unmanned equipment system, which includes an unmanned equipment and the aforementioned unmanned equipment charging station, wherein the battery is detachably mounted on the unmanned equipment.

[0044] The beneficial effects of the battery cooling device in this embodiment of the invention include: the battery cooling device provided in this embodiment of the invention includes a liquid storage tank, an atomizing box, an atomizer, and an opening and closing assembly. The liquid storage tank is provided with a liquid storage chamber and a liquid outlet, and the liquid storage chamber is connected to the liquid outlet. The atomizing box is located at the bottom of the liquid storage tank and has an atomizing chamber. The atomizer is located in the atomizing chamber and is used to atomize the liquid in the atomizing chamber into droplets for cooling the battery. The opening and closing assembly is located at the liquid outlet and is used to open or close the liquid outlet. When the opening and closing assembly opens the liquid outlet, the liquid in the liquid storage chamber enters the atomizing chamber through the liquid outlet. When the opening and closing assembly closes the liquid outlet, the liquid in the liquid storage chamber no longer enters the atomizing chamber through the liquid outlet. By setting the opening and closing components, the liquid in the storage chamber can be replenished into the atomizing chamber as needed, which helps to keep the atomizer in the atomizing chamber at an optimal liquid level. This ensures that the atomizer can work at an optimal liquid level, so as to reliably form droplets and ensure that the battery cooling device maintains a stable mist output, thereby ensuring the stability of the battery cooling effect.

[0045] The unmanned equipment charging station of this invention includes all the beneficial effects of the aforementioned battery cooling device. For example, by setting the opening and closing components, the liquid in the storage chamber can be replenished into the atomizing chamber as needed, which helps to keep the atomizer in the atomizing chamber at a better liquid level, so that the atomizer can work at a better liquid level, ensuring that the atomizer reliably forms droplets, that is, ensuring that the battery cooling device maintains a stable mist output, thereby ensuring the stability of the battery cooling effect.

[0046] The unmanned equipment system of this invention includes all the beneficial effects of the aforementioned unmanned equipment charging station. For example, by setting the opening and closing components, the liquid in the storage chamber can be replenished into the atomizing chamber as needed, which helps to keep the atomizer in the atomizing chamber at a better liquid level, so that the atomizer can work at a better liquid level, ensuring that the atomizer reliably forms droplets, that is, ensuring that the battery cooling device maintains a stable mist output, thereby ensuring the stability of the battery cooling effect.

Detailed Implementation

[0062] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0063] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0064] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0065] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0066] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0067] When a battery cell is discharged or charged at a high rate, it will release a lot of heat; in particular, during high-rate discharge, the temperature of the battery cell can reach above 75°C.

[0068] However, battery charging usually needs to be carried out below 60°C. Since the temperature of the battery cell determines its chemical properties and also affects its charging performance, the battery cannot be charged at high temperatures and must wait for its temperature to drop to a certain level before it can be charged. Otherwise, it will seriously affect the battery's lifespan.

[0069] In the case of frequent high-rate charging and discharging, quickly restoring the discharged battery to the temperature range allowed for charging will significantly improve the operating efficiency of unmanned equipment such as drones and unmanned vehicles that use batteries for power. At the same time, it can protect the battery cells from high temperatures, keep them within the normal operating range, and help extend the battery's lifespan.

[0070] In related technologies, batteries for unmanned equipment are cooled by air or water to accelerate heat dissipation. However, air cooling is limited by ambient temperature and often fails to dissipate heat effectively in hot summers. Water cooling typically requires immersing the battery in water, but since most battery components cannot come into contact with water, only a portion of the battery can be submerged, leaving the remaining portion unable to dissipate heat effectively. Another technology aims to improve battery heat dissipation by atomizing water and combining it with airflow to remove heat from the battery. Since water evaporation carries away a significant amount of heat, the water mist rapidly evaporates and vaporizes on the hot battery surface. Simultaneously, the airflow from a fan further accelerates the evaporation process. This combination of rapid water vaporization and airflow maximizes heat absorption efficiency, allowing the battery to cool down quickly.

[0071] However, the battery cooling devices provided by related technologies that use water mist to cool the battery cannot guarantee that the atomizer is always at the optimal atomizing liquid level, resulting in unstable mist output and thus easily leading to unstable cooling effect.

[0072] In view of this, the battery cooling device, unmanned equipment charging station and unmanned equipment system provided in this embodiment can use the battery cooling device to stably produce fog, ensure the amount of fog produced, and improve the stability and reliability of battery cooling. They will be described in detail below.

[0073] This embodiment provides an unmanned equipment system, which includes unmanned equipment and an unmanned equipment charging station; the unmanned equipment charging station includes a battery, a charging device, and a battery cooling device 010 (e.g., ...). Figure 1 (As shown); The battery is detachably installed on the unmanned equipment to provide power to the unmanned equipment. The battery can be removed from the unmanned equipment and electrically connected to the charging device to charge the battery. The battery can also be cooled by the battery cooling device 010 to ensure that the cooled battery can be reliably charged. That is, when the battery needs to be charged, it can be removed from the unmanned equipment and placed in the battery cooling device 010 to quickly dissipate heat and cool the battery down to a rechargeable temperature. Then the charging device can charge the battery, which shortens the waiting time for the battery to cool down and helps to improve the operating efficiency of the unmanned equipment.

[0074] It should be noted that unmanned equipment can refer to drones, unmanned vehicles, or robots, etc., without specific limitations.

[0075] Further, please refer to Figure 1The battery cooling device 010 includes a liquid storage tank 100, an atomizing box 200, and an atomizer 300. The liquid storage tank 100 has a liquid storage chamber 110 and a liquid outlet 120, which are connected. The atomizing box 200 is located at the bottom of the liquid storage tank 100 and has an atomizing chamber 210. Liquid in the liquid storage chamber 110 can enter the atomizing chamber 210 through the liquid outlet 120. The atomizer 300 is located in the atomizing box 200 and is used to atomize the liquid in the atomizing chamber 210 into droplets for cooling the battery. In this way, the battery can be cooled using droplets.

[0076] The connection methods between the atomizing box 200 and the liquid storage tank 100 include, but are not limited to, connection by fasteners such as bolts, or integral molding.

[0077] Please refer to Figure 1 and Figure 2 The way the atomizer 300 is installed in the atomizing box 200 can be selected as needed. In this embodiment, the bottom of the atomizing box 200 is provided with a mounting hole 211 that communicates with the atomizing chamber 210. The battery cooling device 010 also includes a bottom shell 212. The atomizer 300 is installed on the bottom outer wall of the atomizing box 200 through the bottom shell 212, and the atomizer 300 protrudes from the atomizing chamber 210 through the mounting hole 211, so that the atomizer 300 contacts the liquid in the atomizing chamber 210 through the mounting hole 211 and atomizes the liquid in the atomizing chamber 210 into droplets.

[0078] The structure of the atomizer 300 is similar to that of related technologies. It includes an atomizing plate 310 and a drive plate 320. The atomizing plate 310 is connected to the drive plate 320, and both the atomizing plate 310 and the drive plate 320 are mounted between the bottom shell 212 and the bottom of the atomizing box 200. The atomizing plate 310 protrudes from the atomizing chamber 210 through the mounting hole 211 so as to contact the liquid in the atomizing chamber 210 through the mounting hole 211.

[0079] Optionally, the atomizing plate 310 can also be mounted on the bottom shell 212 by means of a fixing plate 330, and a sealing ring 340 can also be provided between the atomizing plate 310 and the fixing plate 330, so that the atomizing plate 310 can fit tightly against the bottom of the atomizing box 200, thereby improving the problem of liquid in the atomizing chamber 210 leaking into the bottom shell 212 from the gap between the mounting hole 211 and the atomizing plate 310, causing the drive board 320 to short-circuit.

[0080] The bottom shell 212 and the atomizing box 200 can be connected by means including but not limited to bolts or other fasteners, or by snap-fitting; a sealing ring can be installed between the bottom shell 212 and the atomizing box 200.

[0081] Please refer to Figure 1The battery cooling device 010 of this embodiment also includes a battery connection assembly 800, which is detachably connected to the liquid storage tank 100 and the atomizing box 200. The battery connection assembly 800 is used to fix the battery, that is, the battery is detachably mounted on the battery connection assembly 800 of the battery cooling device 010. When the battery is mounted on the battery connection assembly 800, the charging device is electrically connected to the battery to charge the battery.

[0082] It should be understood that in other embodiments, only one of the liquid storage tank 100 and the atomizing box 200 is detachably connected to the battery connection assembly 800; or, in other embodiments, at least one of the liquid storage tank 100 and the atomizing box 200 is movably connected to the battery connection assembly 800, for example, slidably connected, etc., without specific limitation here.

[0083] The structure of the battery connection assembly 800 can be configured as needed. In this embodiment, the battery connection assembly 800 has a receiving space 801 for placing the battery. When no battery is placed in the receiving space 801, the liquid storage tank 100 and the atomizing box 200 can be placed within the receiving space 801. This configuration allows the liquid storage tank 100 and the atomizing box 200 to be placed within the receiving space 801 during the transportation and handling of the battery cooling device 010, reducing the overall volume of the battery cooling device 010. That is, by overlapping the box structures of the battery connection assembly 800, the liquid storage tank 100, and the atomizing box 200, the volume of the battery cooling device 010 is reduced, thereby lowering the packaging and transportation costs of the battery cooling device 010.

[0084] Further, please refer to Figure 1 and Figure 3 The battery connection assembly 800 includes a guide 810, which is detachably disposed on the side wall of the receiving space 801 and is used for sliding engagement with the battery. When the guide 810 is removed from the side wall of the receiving space 801 and no battery is placed in the receiving space 801, the liquid storage tank 100 and the atomizing box 200 can be placed in the receiving space 801. The guide 810 improves the stability of the battery when placed in the receiving space 801, and by configuring the guide 810 to be detachably disposed in the receiving space 801, it can be ensured that the liquid storage tank 100 and the atomizing box 200 can be smoothly stored in the receiving space 801 when no battery is placed in the receiving space, effectively reducing the overall volume of the battery cooling device 010.

[0085] Optionally, the guide member 810 is a guide protrusion, and the outer wall of the battery is provided with a sliding groove, which slides in conjunction with the guide protrusion. This design ensures the ease of installation and removal of the battery in the receiving space 801, as well as the stability of the battery assembly in the receiving space 801.

[0086] Furthermore, the battery connection assembly 800 also includes a connector 820, two guides 810, two supports 821, two first side plates 830, and two second side plates 840. The two supports 821 are connected by the connector 820. The two first side plates 830 are connected to one of the supports 821 and are spaced apart in the vertical direction. The two second side plates 840 are connected to the other support 821 and are spaced apart in the vertical direction. A receiving space 801 is formed between the two first side plates 830 and the two second side plates 840. One of the first side plates 830 is detachably connected to one of the guides 810, and one of the second side plates 840 is detachably connected to the other guide 810. The two opposite side walls of the battery are provided with sliding grooves, and the two sliding grooves slide in a one-to-one correspondence with the two guides 810. This design ensures ease of battery installation and removal within the housing space 801, as well as stability of battery assembly within the housing space 801. Furthermore, the space space 801, with its openwork portion, is formed by two spaced-apart first side plates 830 and two spaced-apart second side plates 840, thereby achieving a lightweight structure for the battery connection assembly 800. This reduces the overall weight of the battery cooling device 010 and makes it easier to transport.

[0087] Optionally, the first side plate 830 and the second side plate 840 have the same structure and shape; this reduces the investment in molds and helps improve the assembly and production efficiency of the battery connection assembly 800. The following description will take the structure of the first side plate 830 as an example.

[0088] Please refer to Figure 3 and Figure 4 The first side plate 830 includes a first plate 831 and a second plate 832 connected at an angle, so that the first side plate 830 is approximately "L"-shaped. The second plate 832 is connected to the support member 821. The first plate 831 and the second side plate 840 are distributed opposite to each other, and a receiving space 801 is formed between them. This arrangement can ensure the overall stability of the battery connection assembly 800.

[0089] The first plate 831 and the second plate 832 are connected by a single molding, and the included angle between them is 90°.

[0090] Of course, in other embodiments, the connection method of the first plate 831 and the second plate 832 can also be welding, connection by fasteners such as bolts, etc., and the included angle between the two is 88°, 93°, etc., which are not specifically limited here.

[0091] In this embodiment, the second plate 832 and the support member 821 are connected by bolts; of course, in other embodiments, the connection method between the second plate 832 and the support member 821 can also be welding, etc., which is not specifically limited here.

[0092] Furthermore, the bolts connecting the second plate 832 of one of the first side plates 830 and the support member 821 also connect the connector 820; thus, the number of bolts required can be reduced to lower costs.

[0093] Please refer to Figure 1 , Figure 3 and Figure 4 In this embodiment, the end of the first plate 831 of one of the first side plates 830 away from the second plate 832 is detachably connected to the liquid storage tank 100, and the end of the first plate 831 of the other first side plate 830 away from the second plate 832 is detachably connected to the atomizing box 200. This arrangement ensures the assembly stability of the liquid storage tank 100 and the atomizing box 200 when the battery is cooled by the battery cooling device 010 placed in the receiving space 801. It also allows the liquid storage tank 100 and the atomizing box 200 to be easily separated from the corresponding first side plate 830 when the battery cooling device 010 is transported and packaged, and then the liquid storage tank 100 and the atomizing box 200 can be stored in the receiving space 801.

[0094] Furthermore, the end of the first plate 831 of one of the first side plates 830 away from the second plate 832 is detachably connected to the liquid storage tank 100 by bolts, and the end of the first plate 831 of the other first side plate 830 away from the second plate 832 is also detachably connected to the atomizing box 200 by bolts. Of course, in other embodiments, the end of the first plate 831 of one of the first side plates 830 away from the second plate 832 may also be detachably connected to the liquid storage tank 100 by snap-fit, and the end of the first plate 831 of the other first side plate 830 away from the second plate 832 may also be detachably connected to the atomizing box 200 by snap-fit; no specific limitation is made here.

[0095] Alternatively, please refer to Figure 4 and Figure 5One end of the first plate 831 away from the second plate 832 is connected to a limiting rib 833; the limiting rib 833 connected to the end of the first plate 831 of one of the first side plates 830 away from the second plate 832 can abut against the liquid storage tank 100, and the limiting rib 833 connected to the end of the first plate 831 of the other first side plate 830 away from the second plate 832 can abut against the atomizing box 200; in this way, when the liquid storage tank 100 and the atomizing box 200 are moved out of the receiving space 801 and connected to the end of the first plate 831 of the corresponding first side plate 830 away from the second plate 832, the limiting rib 833 can be used to position the relative positions between the battery connection assembly 800, the liquid storage tank 100 and the atomizing box 200, ensuring the accuracy of assembly.

[0096] Alternatively, please refer to Figure 3 and Figure 4 The support member 821 includes a third plate 822 and a fourth plate 823 connected at an angle. The support member 821 is roughly "L"-shaped. The second plate 832 is connected to the fourth plate 823, and the first plate 831 is connected to the third plate 822. This arrangement can improve the stability of the connection between the first side plate 830 and the support member 821.

[0097] Furthermore, the second plate 832 and the fourth plate 823 are connected by bolts, and the bolts also connect the connector 820. The connection method of the first plate 831 and the third plate 822 is similar to that of the second plate 832 and the fourth plate 823, and will not be described in detail here.

[0098] Furthermore, the support member 821 also includes a reinforcing rib 824, which is connected between the third plate 822 and the fourth plate 823.

[0099] The third plate 822 and the fourth plate 823 are connected by a single molding, and the included angle between them is 90°.

[0100] Of course, in other embodiments, the connection method between the third plate 822 and the fourth plate 823 can also be welding, connection by fasteners such as bolts, etc., and the included angle between the two is 88°, 93°, etc., which are not specifically limited here.

[0101] Alternatively, please refer to Figure 1 and Figure 3 The battery connection assembly 800 also includes a charging plug 850, which is connected to the connector 820 and to the charging device. The connection method includes, but is not limited to, detachable connection (e.g., plug-in) and fixed connection. When the battery is placed in the receiving space 801, the battery is plugged into the charging plug 850, so that the battery can be connected to the charging device through the charging plug 850, and then the charging device can be used to charge the battery.

[0102] Optionally, the atomizer 300 can be electrically connected to a charging device via a charging plug 850, thereby allowing the charging device to power the atomizer 300. Alternatively, in other embodiments, the atomizer 300 can be directly connected to other power sources, without specific limitations.

[0103] Alternatively, please refer to Figure 3 The battery connection assembly 800 also includes a foot pedal 860, which is spaced vertically from the connector 820. One end of the foot pedal 860 is bolted to one of the support members 821 and the second plate 832 of the lower first side plate 830, while the other end is bolted to another support member 821 and the second plate 832 of the lower second side plate 840. The foot pedal 860 provides support for the entire battery cooling device 010. Furthermore, because the battery cooling device 010 is lightweight, to prevent it from being lifted when removing the battery from the receiving space 801, the worker can step on the supporting foot pedal 860 before removing the battery. Additionally, when the battery, atomizing box 200, and liquid storage tank 100 are placed in the receiving space 801, the foot pedal 860 also provides support for the battery or atomizing box 200. The specific structure of the foot pedal 860 is similar to related technologies and will not be described in detail here.

[0104] It should be understood that in other embodiments, the foot pedal 860 may be connected only to the support member 821, or only to the first side plate 830 and the second side plate 840. The connection method may also be welding, etc., which are not specifically limited here.

[0105] The connection method between the guide member 810 and the first side plate 830 is similar to the connection method between the guide member 810 and the second side plate 840. Here, only the connection method between the guide member 810 and the first side plate 830 is described as an example.

[0106] Please refer to Figure 3 , Figure 4 and Figure 6 The first plate 831 of the first side plate 830 is provided with two first slots 834, which extend vertically. The two sides of the guide member 810 are detachably inserted into the two first slots 834 in a one-to-one correspondence. This arrangement ensures the ease of installation and removal of the guide member 810.

[0107] Furthermore, the first plate 831 has a mating surface 835, and the first plate 831 is connected to two first protruding ribs 836. The two first protruding ribs 836 are opposite to each other and spaced apart. Each first protruding rib 836 is spaced apart with mating surfaces 835 to form a first slot 834. Both ends of the guide member 810 are provided with mating parts 811, and each mating part 811 includes two second protruding ribs 812. The second protruding ribs 812 are connected to the guide member 810. The two second protruding ribs 812 of each mating part 811 are spaced apart and form a second slot 813. The two mating parts 811 are inserted into the two first slots 834 in a one-to-one correspondence. Specifically, one of the second protruding ribs 812 of each mating part 811 is inserted into the corresponding first slot 834, and the first protruding rib 836 on the corresponding side is inserted into the second slot 813. The other second protruding rib 812 overlaps on the side of the corresponding first protruding rib 836 away from the first slot 834. The guide member 810 is in contact with the mating surface 835. This configuration allows a snap-fit ​​structure to be formed between the guide member 810 and the first plate 831, thereby improving the problem that the guide member 810 is prone to detaching from the first plate 831 in the direction perpendicular to the mating surface 835 and in the direction from one first slot 834 to the other first slot 834, thus ensuring the reliability of the guide member 810 in the receiving space 801.

[0108] Optionally, the width of the first protrusion 836 is adapted to the width of the second slot 813, and the width of the second protrusion 812 is adapted to the width of the first slot 834; this arrangement can improve the situation where the conductive component shakes when connected to the first plate 831.

[0109] Furthermore, the guide member 810 is detachably connected to the first plate 831 by bolts to further improve the stability of the guide member 810 assembled in the receiving space 801 and improve the problem that the guide member 810 is prone to accidentally sliding off the first plate 831 in the vertical direction.

[0110] It should be understood that in other embodiments, the guide 810 may be detachably connected to the first plate 831 by bolts only, without being specifically limited here.

[0111] Please refer to Figure 2 , Figure 7 and Figure 8The battery cooling device 010 of this embodiment also includes an opening and closing component 400, which is disposed at the liquid outlet 120 and used to open or close the liquid outlet 120. When the opening and closing component 400 opens the liquid outlet 120, the liquid in the storage chamber 110 enters the atomizing chamber 210 through the liquid outlet 120. When the opening and closing component 400 closes the liquid outlet 120, the liquid in the storage chamber 110 does not flow through the liquid outlet 120 and therefore cannot replenish the atomizing chamber 210. By configuring the opening and closing component 400, the liquid in the storage chamber 110 can be replenished into the atomizing chamber 210 as needed, thereby helping to maintain the atomizer 300 disposed in the atomizing chamber 210 at an optimal liquid level. This ensures that the atomizer 300 can operate at an optimal liquid level, ensuring that the atomizer 300 reliably forms droplets, thus ensuring that the battery cooling device 010 maintains a stable mist output and ensuring the stability of the battery cooling effect.

[0112] Furthermore, the opening and closing assembly 400 includes a float 410 and a valve 420. The valve 420 is disposed at the liquid outlet 120, and the float 410 is rotatably disposed within the atomizing chamber 210 and configured to enable the valve 420 to open the liquid outlet 120. When the liquid level in the atomizing chamber 210 reaches a first preset liquid level, the float 410 rotates under its own weight, thereby opening the liquid outlet 120. When the liquid level in the atomizing chamber 210 reaches a second preset liquid level, the float 410 resets under the action of buoyancy, and the valve 420 closes the liquid outlet 120. The second preset liquid level is higher than the first preset liquid level. In this way, the outlet 120 can be automatically opened or closed according to the liquid level in the atomizing chamber 210, so that the atomizer 300 always works under the optimal atomizing liquid level conditions. That is, when the liquid level in the atomizer 300 drops, the float 410 can drive the valve 420 to realize the automatic water replenishment mechanism to maintain the liquid level in the atomizer 300, ensuring that the atomizer 300 is always below a certain liquid level, ensuring a stable and sufficient amount of mist output.

[0113] Furthermore, please refer to Figure 9Valve 420 includes a valve body 421 and an elastic element 422. The valve body 421 is movably disposed at the liquid outlet 120 for opening or closing the liquid outlet 120. The elastic element 422 is configured to elastically engage with the valve body 421. A float 410 is driven by the valve body 421. When the liquid level in the atomizing chamber 210 reaches a first preset liquid level, the float 410 rotates under its own weight, pushing the valve body 421 and overcoming the elastic force of the elastic element 422 to open the liquid outlet 120. When the liquid level in the atomizing chamber 210 reaches a second preset liquid level, the float 410 resets under buoyancy, and the valve body 421 resets to close the liquid outlet 120 under the elastic force of the elastic element 422. The elastic element 422 reliably drives the valve body 421 to close the liquid outlet 120 when the liquid level in the atomizer 300 rises.

[0114] It should be understood that valve 420 can refer to a one-way valve. When the one-way valve is not pushed by float 410, the valve body outlet is closed, that is, the path of liquid flowing from storage chamber 110 to atomizing chamber 210 is blocked. It requires float 410 to push the valve core upward in order to open the valve body outlet and open the path of liquid flowing from storage chamber 110 to atomizing chamber 210.

[0115] In other embodiments, valve 420 includes only valve body 421, and float 410 is driven to cooperate with valve body 421. When the liquid level in atomizing chamber 210 reaches the first preset liquid level, float 410 rotates under its own weight and drives valve body 421 to move to open liquid outlet 120. When the liquid level in atomizing chamber 210 reaches the second preset liquid level, float 410 resets under the action of buoyancy and causes valve body 421 to move in the opposite direction to reset to close liquid outlet 120.

[0116] Optionally, the elastic element 422 can be a spring or an elastic sleeve, etc., without specific limitation. The elastic element 422 can be connected between the valve body 421 and the liquid storage tank 100, or between the valve body 421 and the atomizing box 200, without specific limitation.

[0117] Optionally, the float 410 includes a float body 411 and a pusher 412 connected to the end of the float body 411. The float body 411 is rotatably disposed within the atomizing chamber 210, and the pusher 412 is in transmission cooperation with the valve body 421. When the liquid level in the atomizing chamber 210 reaches a first preset liquid level, the float body 411 rotates under its own weight, driving the pusher 412 to move, thereby pushing the valve body 421 and overcoming the elastic force of the elastic member 422 to open the liquid outlet 120. When the liquid level in the atomizing chamber 210 reaches a second preset liquid level, the float body 411, under the action of buoyancy, drives the pusher 412 to exit the reset trajectory of the valve body 421, and the valve body 421 resets under the elastic force of the elastic member 422 and closes the liquid outlet 120. The pusher 412 reliably pushes the valve body 421 to open the liquid outlet 120 when the liquid level decreases.

[0118] Optionally, the float 410 has a first end and a second end, the axis of rotation of the float 410 is located between the first end and the second end, and the first end is in drive engagement with the valve 420 to open or close the outlet 120; the distance from the first end to the axis of rotation is less than the distance from the second end to the axis of rotation; specifically, the float body 411 has a first end and a second end, the axis of rotation of the float body 411 is located between the first end and the second end, and the first end is connected to a pusher 412; when the liquid level in the atomizing chamber 210 reaches a first preset liquid level, the float body 411, under its own weight... Under the action of buoyancy, the second end of the float body 411 rotates downward, and the first end of the float body 411 drives the pusher 412 to rotate upward, so as to use the pusher 412 to push the valve body 421 and overcome the elastic force of the elastic member 422 to open the liquid outlet 120; when the liquid level in the atomizing chamber 210 reaches the second preset liquid level, the second end of the float body 411 rotates upward under the action of buoyancy, and the first end of the float body 411 rotates downward to drive the pusher 412 to exit the reset trajectory of the valve body 421. The valve body 421 resets under the elastic force of the elastic member 422 and closes the liquid outlet 120.

[0119] By making the distance from the first end to the rotation axis smaller than the distance from the second end to the rotation axis, the float body 411 can rotate more flexibly with the rise and fall of the liquid level, thereby ensuring the sensitivity of the opening and closing of the liquid outlet 120.

[0120] It should be noted that, in order to ensure the sensitivity of the float 410 as it rotates with the liquid level, the density of the material used to make the float 410 is less than the density of the liquid in the atomizing chamber 210. For example, when the liquid in the atomizing chamber 210 and the liquid storage chamber 110 is water, the density of the material used to make the float 410 is less than the density of water.

[0121] Optionally, a hollow groove 414 is provided on the side of the float body 411 away from the liquid storage tank 100, so that the liquid in the atomizing chamber 210 can enter the hollow groove 414, so that the float 410 can rotate and reset more sensitively when the liquid level rises.

[0122] Please refer to Figure 2 and Figure 10 In this embodiment, a support base 220 is provided inside the atomizing chamber 210. The float 410 includes a float body 411 and a rotating shaft 413 connected to the float body 411. The rotating shaft 413 is rotatably disposed on the support base 220. The float body 411 is configured to enable the valve 420 to open the liquid outlet 120. By supporting the float body 411 with the support base 220, it is ensured that the float body 411 rotates smoothly within the atomizing chamber 210.

[0123] Furthermore, the atomizing chamber 210 is provided with two spaced-apart support seats 220, each with a groove 221. Specifically, one support seat 220 has a groove 221 with an open top on the side facing the other support seat 220. The battery cooling device 010 also includes a fixing member 230. Both ends of the rotating shaft 413 are rotatably inserted into the grooves 221 of the two support seats 220, respectively. The fixing member 230 is connected to at least one of the two support seats 220 and prevents the rotating shaft 413 from disengaging from the grooves 221. This arrangement ensures the ease of operation of the float 410, which is rotatably mounted in the atomizing chamber 210.

[0124] Furthermore, a first clearance space 222 is formed between the two support bases 220, and a second clearance space 231 is provided on the side of the fixing frame facing the first clearance space 222. Both the first clearance space 222 and the second clearance space 231 are used to avoid the float 410. This arrangement can prevent the float 410 from being interfered with by the support base 220 or the fixing member 230 when it rotates.

[0125] The connection methods between the fastener 230 and the support 220 include, but are not limited to, connection with fasteners such as bolts, snap-fit, and adhesive.

[0126] It should be understood that in other embodiments, please refer to Figure 11The opening and closing assembly 400 includes a float 410, which is rotatably disposed within the atomizing chamber 210. The float 410 has a first end 4101 and a second end 4102 that are relatively distributed. The first end 4101 can open or close the liquid outlet 120. The distance between the second end 4102 and the rotation axis of the float 410 is smaller than the distance between the first end 4101 and the rotation axis of the float 410. When the liquid level in the atomizing chamber 210 reaches a first preset liquid level, the float 410 rotates under its own weight, causing the first end 4101 to move downward to open the liquid outlet 120. When the liquid level in the atomizing chamber 210 reaches a second preset liquid level, the float 410 resets under the action of buoyancy, causing the first end 4101 to move upward to close the liquid outlet 120. The second preset liquid level is higher than the first preset liquid level.

[0127] Alternatively, in other embodiments, the opening / closing component 400 may also be a solenoid valve disposed at the liquid outlet 120. The battery cooling device 010 further includes a liquid level sensor disposed in the atomization chamber 210 and connected (communicating) with the solenoid valve. When the liquid level sensor detects that the liquid level in the atomization chamber 210 reaches a first preset liquid level, the liquid level sensor sends first control information to the solenoid valve, and the solenoid valve opens the liquid outlet 120. When the liquid level sensor detects that the liquid level in the atomization chamber 210 reaches a second preset liquid level, the liquid level sensor sends second control information to the solenoid valve, and the solenoid valve closes the liquid outlet 120.

[0128] Please refer to Figure 12 and Figure 13 The battery cooling device 010 in this embodiment further includes a mist channel 500 and a mist outlet 501 communicating with the mist channel 500. The mist channel 500 is also communicating with the atomization chamber 210, so that the mist droplets in the atomization chamber 210 are guided through the mist channel 500 and output from the mist outlet 501. With this configuration, it can be ensured that the mist droplets formed in the atomization chamber 210 are reliably output through the mist channel 500 and the mist outlet 501, so as to reliably utilize the mist droplets to cool the battery.

[0129] Furthermore, the mist channel 500 includes a first channel 510 and a second channel 520 that are interconnected. The end of the first channel 510 away from the second channel 520 is connected to the atomizing chamber 210, and the second channel 520 is connected to the mist outlet 501. The second channel 520 is an flared channel, with the inner diameter of the end of the second channel 520 closer to the first channel 510 being smaller than the inner diameter of the end of the second channel 520 away from the first channel 510. The flared second channel 520 allows the mist droplets to be output more evenly from the mist outlet 501, thereby providing more efficient, reliable, and uniform cooling to the battery.

[0130] Optionally, the inner diameter of the second channel 520 gradually increases from the end near the first channel 510 to the end away from the first channel 510, so that the second channel 520 is approximately flared and funnel-shaped. This configuration allows the droplets to be guided more evenly through the second channel 520 for output.

[0131] Furthermore, the inner diameter of the first channel 510 is less than or equal to the inner diameter of the end of the second channel 520 that connects to the first channel 510. In this way, the smaller inner diameter of the first channel 510 can be used to concentrate the output of the mist droplets formed in the atomizing chamber 210, ensuring smoother and faster mist output and improving the eddy current problem; it can also improve the problem of uneven distribution of mist droplets caused by airflow.

[0132] Optionally, the inner diameter of the first channel 510 is narrower than the width of the atomizing cavity 210, so that the droplets in the atomizing cavity 210 can be concentratedly discharged through the first channel 510. Because the first channel 510 is relatively narrow, it can guide and discharge the droplets formed in the atomizing cavity 210 in a concentrated manner, thereby improving the problem of droplets not being evenly dispersed and discharged due to airflow, and enhancing the uniformity and stability of using mist to dissipate heat from the battery.

[0133] The statement that the inner diameter of the first channel 510 is narrower than the width of the atomizing cavity 210 can be interpreted as follows: when the orthographic projections of the first channel 510 and the atomizing cavity 210 are on a horizontal plane, the width of the first channel 510 in any direction on the horizontal plane is smaller than the width of the atomizing cavity 210 in any direction on the horizontal plane. Alternatively, it can be understood that the area of ​​the orthographic projection of the first channel 510 on the horizontal plane is smaller than the area of ​​the orthographic projection of the atomizing cavity 210 on the horizontal plane.

[0134] Alternatively, please refer to Figure 1 and Figure 12 The second channel 520 is also provided with a flow divider 521, which is used to disperse the mist that enters the second channel 520 from the first channel 510 to improve the uniformity of the mist.

[0135] The specific number of diversion ribs 521 can be selected as needed, such as one, two, three, four, five, etc., and is not specifically limited here.

[0136] In some embodiments, the second channel 520 is provided with a plurality of flow dividers 521 (two or more), and the spacing between any two flow dividers 521 gradually increases from the end closer to the first channel 510 to the end farther away from the first channel 510. This arrangement can improve the uniform dispersion of the mist and ensure the uniformity of the mist output from the mist outlet 501.

[0137] Optionally, the first channel 510 and the second channel 520 are arranged sequentially in the vertical direction, with the first channel 510 located below the second channel 520. This arrangement can reliably guide the droplets in the atomizing chamber 210 located below the liquid storage tank 100 upwards, ensuring that the droplets can more comprehensively cover the battery, thereby improving the battery's heat dissipation effect.

[0138] Optionally, the mist channel 500 is disposed in the liquid storage tank 100 and distributed on the side of the liquid storage tank 100 facing the receiving space 801. This arrangement allows the battery cooling device 010 to have a more compact structure, which is beneficial to reducing the overall size of the battery cooling device 010.

[0139] Furthermore, the mist channel 500 is integrally formed with the liquid storage tank 100. Of course, in other embodiments, the mist channel 500 can also be disposed in the liquid storage tank 100 by means of bonding, snap-fitting, etc., which is not specifically limited here.

[0140] In this embodiment, please refer to Figure 1 and Figure 13 The liquid storage tank 100 is provided with an airflow channel 600, one end of which is open and the other end is connected to the mist outlet 501. The battery cooling device 010 also includes a fan 700, which is located at the airflow channel 600 to blow the mist droplets entering the airflow channel 600 out of the airflow channel 600 and allow the mist droplets to enter the receiving space 801 with the airflow. The fan 700 can reliably blow the droplets towards the battery, and at the same time, the airflow of the fan 700 can be used to cool the battery. This maximizes the heat absorption efficiency by combining the rapid vaporization of water mist with the airflow, allowing the battery to cool down quickly in a short time.

[0141] Furthermore, when the liquid storage tank 100 and the atomizing box 200 are removed from the receiving space 801, the airflow channel 600 is positioned opposite to the receiving space 801, the fan 700 is located at the opening of the airflow channel 600 at the end furthest from the receiving space 801, and the mist outlet 501 is closer to the receiving space 801 than the fan 700. This arrangement allows for more reliable blowing of mist droplets onto the battery placed inside the receiving space 801, improving the battery's cooling efficiency.

[0142] Optionally, the liquid storage tank 100 has an annular cavity structure, and the liquid storage tank 100 surrounds and defines the airflow channel 600, that is, the liquid storage cavity 110 of the liquid storage tank 100 surrounds the airflow channel 600; please refer to Figure 1 , Figure 12 and Figure 13The second channel 520 and the diverter rib 521 disposed in the second channel 520 both extend into the airflow channel 600. Along the axial direction of the airflow channel 600, one end of the second channel 520 is an air inlet 522, and the other end is a mist outlet 501 communicating with the air inlet 522. The mist outlet 501 is opposite to the receiving space 801. This arrangement allows the air blown by the fan 700 to reliably blow from the air inlet 522 to the mist outlet 501, so as to efficiently blow the airflow and mist droplets into the receiving space 801, improve the cooling efficiency of the battery, and ensure the compact structural design of the liquid storage tank 100, thereby ensuring the overall miniaturization design of the battery cooling device 010.

[0143] Optionally, the fan 700 can be electrically connected to a charging device via a charging plug 850, thereby allowing the charging device to power the fan 700. Alternatively, in other embodiments, the fan 700 can be directly connected to other power sources, without specific limitations.

[0144] Please refer to Figure 7 and Figure 13 The battery cooling device 010 in this embodiment also includes a rectifier 710, which is disposed on the air outlet side of the fan 700 to convert the rotating airflow blown out by the fan 700 into a straight airflow. This arrangement can improve the problem of vortex formation in the airflow blown out by the fan 700, improve the uniformity of the airflow, and improve the heat dissipation efficiency and uniformity of the battery.

[0145] Furthermore, the rectifier 710 has a plurality of air holes 711 arranged in an array. This arrangement enables the air blown by the fan 700 to be output from the plurality of air holes 711 arranged in an array, so as to reliably convert the rotating airflow into a straight and uniform multi-stream airflow, ensuring good rectification effect, that is, ensuring the uniformity of the airflow and improving the uniformity of heat dissipation of the battery.

[0146] Optionally, both the fan 700 and the rectifier 710 are mounted within the airflow channel 600, with the side of the rectifier 710 facing away from the fan 700 opposite to the air inlet 522 of the second channel 520. The airflow from the fan 700 is rectified by the rectifier 710, then blown into the second channel 520 through the air inlet 522, and subsequently blown out from the mist outlet 501 and into the receiving space 801. This allows both airflow and mist droplets to be blown into the receiving space 801 together, improving the battery's cooling efficiency.

[0147] Furthermore, the second channel 520 has an air outlet at the end away from the first channel 510, and the end of the second channel 520 away from the first channel 510 is spaced apart from the top of the airflow channel 600; a portion of the airflow rectified by the rectifier 710 is blown into the second channel 520 through the air inlet 522, and then blown out from the mist outlet 501 and into the receiving space 801; another portion of the airflow rectified by the rectifier 710 is blown through the gap between the second channel 520 and the top of the airflow channel 600, so as to bring the mist droplets output from the air outlet of the second channel 520 into the receiving space 801.

[0148] It should be understood that in other embodiments, the mist outlet 501 may also be located on the bottom wall of the airflow channel 600 and communicate with the airflow channel 600, that is, neither the second air duct nor the diverter 521 located in the second air duct extends into the airflow channel 600; along the vertical direction, the fan 700 and the rectifier 710 are both located above the mist outlet 501, and both ends of the airflow channel 600 have openings, with the fan 700 located adjacent to one of the openings and the mist outlet 501 located close to the other opening. The airflow blown out by the fan 700 is rectified by the rectifier 710 and blown over the mist outlet 501, then blown into the receiving space 801 from the opening of the airflow channel 600 away from the fan 700. The airflow is rectified into a straight airflow by the rectifier 710 and blown above the mist outlet 501, where it mixes with the uniformly guided mist droplets from the second channel 520 and blown towards the battery, improving the battery's cooling efficiency.

[0149] Optionally, the liquid storage tank 100 is connected to a support rib 610, which is located within the airflow channel 600. The fan 700 and the rectifier 710 are connected to the support rib 610 together by fasteners.

[0150] Furthermore, the airflow channel 600 has multiple support ribs 610, which are distributed circumferentially around the airflow channel 600. The fan 700 and the rectifier 710 are connected to the support ribs 610 one-to-one by multiple fasteners. This arrangement ensures the stability of the fan 700 and the rectifier 710 in the airflow channel 600 and avoids interference from the support ribs 610 to the airflow from the fan 700, thus ensuring good battery heat dissipation.

[0151] Optionally, the outer peripheral wall of the rectifier 710 abuts against the inner wall of the airflow channel 600 to improve the problem of air leakage between the outer periphery of the rectifier 710 and the inner wall of the airflow channel 600.

[0152] Of course, in other embodiments, a certain gap may be left between the outer peripheral wall of the rectifier 710 and the inner wall of the airflow channel 600, which is not specifically limited here.

[0153] In this embodiment, when charging the battery installed on the unmanned equipment, the unmanned equipment system can remove the battery from the unmanned equipment and then install it in the receiving space 801 of the battery connection assembly 800 of the battery cooling device 010. The battery is cooled by the mist generated in the atomizing chamber 210 by the atomizer 300 and the airflow blown out by the fan 700, and the cooled battery is charged by the charging device.

[0154] In summary, the battery cooling device 010 of the present invention can be used in the unmanned equipment charging station of the unmanned equipment system. The battery cooling device 010 can maintain a stable amount of mist output, thereby ensuring the stability of battery cooling.

[0155] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
