Description

Technical Field

[0001] The utility model relates to the technical field of battery heat dissipation, and in particular to a battery cooling device, an unmanned equipment charging station and an unmanned equipment system. Background Art

[0002] In the related art, batteries of unmanned equipment (e.g., drones, unmanned vehicles, robots, etc.) are cooled by air or water to accelerate heat dissipation. However, since air cooling is limited by ambient temperature, it is often difficult to dissipate heat well in hot summer. Water cooling usually requires immersing the battery in water, but since most parts of the battery cannot be exposed to water, only a part of the battery can be immersed in water, which results in the other part of the battery still not being able to effectively dissipate heat.

[0003] There are also related technologies that, in order to improve the heat dissipation effect of the battery, atomize water and combine it with airflow to remove the heat from the battery. Since water evaporation will take away 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 water. By combining the rapid vaporization of water mist with airflow, the heat absorption efficiency can be maximized, allowing the battery to quickly cool down in a short period of time.

[0004] However, the battery cooling device provided by the related art that uses water mist to cool the battery has an unstable mist output, which easily leads to the problem of unstable cooling effect. Utility Model Content

DETAILED DESCRIPTION

[0062] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0063] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0064] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0065] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate the description of this utility model and simplify the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., etc., are used solely for distinction and should not be construed as indicating or implying relative importance.

[0066] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0067] When the battery cell is discharged or charged at a high rate, it will release a large amount of heat. During the use of high-rate discharge, the battery cell temperature 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 under high temperature conditions and must wait for its temperature to drop to a certain level before charging. Otherwise, the battery life will be seriously affected.

[0069] In the case of frequent high-rate charge and discharge, 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 to provide 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 life.

[0070] In related technologies, batteries for unmanned equipment use air cooling or water cooling to accelerate heat dissipation. Air cooling is limited by ambient temperature and often fails to dissipate heat effectively in the hot summer. Water cooling typically requires immersing the battery in water. However, since most battery parts cannot be exposed to water, only a portion of the battery can be immersed in water, leaving the remaining portion unable to dissipate heat effectively. Another related technology, to improve the heat dissipation effect of batteries, atomizes water and combines it with airflow to remove heat from the battery. Because water evaporation removes a large amount of heat, the water mist quickly evaporates and vaporizes on the high-temperature battery surface. The airflow from the fan further accelerates the evaporation of water. This rapid vaporization of the water mist combined with airflow maximizes heat absorption efficiency, allowing the battery to cool quickly in a short period of time.

[0071] However, the battery cooling device provided by the related art that uses water mist to cool the battery cannot ensure that the atomizer is always located at the optimal atomization liquid level, resulting in unstable mist output, which in turn easily leads 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 utilize the battery cooling device to stably discharge mist, ensure the amount of mist output, and improve the stability and reliability of battery cooling, which will be described in detail below.

[0073] This embodiment provides an unmanned equipment system, which includes an 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 (such as Figure 1 As shown); the battery is detachably installed in the unmanned equipment to provide power for the unmanned equipment, and the battery can be removed from the unmanned equipment and electrically connected to the charging device to charge the battery using the charging device, and 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, the battery can be removed from the unmanned equipment and placed in the battery cooling device 010, so that the battery cooling device 010 can be used to quickly dissipate heat and cool the battery, so that the battery temperature is reduced to a charging temperature, and then the charging device can charge the battery, which shortens the time waiting for the battery to cool down, and is conducive to improving the operating efficiency of the unmanned equipment.

[0074] It should be noted that unmanned equipment may refer to drones, unmanned vehicles or robots, etc., and is not specifically limited here.

[0075] For further information, please refer to Figure 1The battery cooling device 010 includes a liquid storage tank 100, an atomizer tank 200, and an atomizer 300. The liquid storage tank 100 is provided with a liquid storage chamber 110 and a liquid outlet 120, and the liquid storage chamber 110 is connected to the liquid outlet 120. The atomizer tank 200 is arranged at the bottom of the liquid storage tank 100 and has an atomizer chamber 210. The liquid in the liquid storage chamber 110 can enter the atomizer chamber 210 through the liquid outlet 120. The atomizer 300 is arranged in the atomizer tank 200 and is used to atomize the liquid in the atomizer chamber 210 into droplets for cooling the battery. In this way, the droplets can be used to cool the battery.

[0076] The connection method between the atomizer box 200 and the liquid storage box 100 includes but is not limited to connection through fasteners such as bolts and integral molding.

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

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

[0079] Optionally, the atomizing sheet 310 can also be set on the bottom shell 212 through the fixing sheet 330, and a sealing ring 340 can also be set between the atomizing sheet 310 and the fixing sheet 330, so that the atomizing sheet 310 can fit tightly to the bottom of the atomizing box 200, so as to improve the problem that the liquid in the atomizing chamber 210 leaks into the bottom shell 212 from the gap between the mounting hole 211 and the atomizing sheet 310 and causes the driving plate 320 to short-circuit.

[0080] The connection method between the bottom shell 212 and the atomizer box 200 includes but is not limited to connection with fasteners such as bolts and clamping; a sealing rubber ring can be provided between the bottom shell 212 and the atomizer box 200.

[0081] Please refer to Figure 1The battery cooling device 010 of this embodiment further includes a battery connecting assembly 800, which is detachably connected to the liquid storage tank 100 and the atomization box 200. The battery connecting assembly 800 is used to fix the battery, that is, the battery is detachably assembled to the battery connecting assembly 800 of the battery cooling device 010, and when the battery is installed in the battery connecting assembly 800, the charging device and the battery are electrically connected to charge the battery.

[0082] It should be understood that in other embodiments, only one of the liquid storage tank 100 and the atomizer 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 atomizer box 200 is movably connected to the battery connection assembly 800, for example, slidably connected, etc., which is not specifically limited 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 storage space 801 for arranging batteries. When no batteries are arranged in the storage space 801, the liquid storage tank 100 and the atomization box 200 can be arranged in the storage space 801. In this way, during the transportation and handling of the battery cooling device 010, the liquid storage tank 100 and the atomization box 200 can be arranged in the storage space 801, thereby 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 atomization box 200, the volume of the battery cooling device 010 is reduced, thereby reducing the packaging and transportation costs of the battery cooling device 010.

[0084] For further information, please refer to Figure 1 and Figure 3 The battery connection assembly 800 includes a guide member 810, which is detachably mounted on the side wall of the storage space 801 and is used for sliding engagement with the battery. When the guide member 810 is removed from the side wall of the storage space 801 and no battery is disposed in the storage space 801, the liquid storage tank 100 and the atomizer box 200 can be disposed in the storage space 801. The provision of the guide member 810 can improve the stability of the battery when disposed in the storage space 801. Configuring the guide member 810 to be detachably mounted in the storage space 801 ensures that the liquid storage tank 100 and the atomizer box 200 can be smoothly accommodated in the storage space 801 when no battery is disposed in the storage space 801, thereby 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 slide groove, which slides in cooperation with the guide protrusion. This arrangement can ensure that the battery can be easily assembled and disassembled into the storage space 801, and ensure the stability of the battery assembled into the storage space 801.

[0086] Furthermore, the battery connection assembly 800 also includes a connecting member 820, two guide members 810, two support members 821, two first side plates 830 and two second side plates 840, the two support members 821 are connected by the connecting member 820; the two first side plates 830 are connected to one of the support members 821, and are spaced apart in the up and down directions; the two second side plates 840 are connected to the other support member 821, and are spaced apart in the up and down directions; a accommodating 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 guide members 810, and one of the second side plates 840 is detachably connected to the other guide member 810; the two opposite side walls of the battery are provided with sliding grooves, and the two sliding grooves are slidably matched with the two guide members 810 in a one-to-one correspondence. Such a configuration can, on the one hand, ensure the operability of disassembling and assembling the battery in the accommodating space 801, and ensure the stability of the battery assembled in the accommodating space 801; on the other hand, it can form a side wall of the accommodating space 801 with a hollow portion through the two first side plates 830 distributed at intervals and the two second side plates 840 distributed at intervals, thereby realizing a lightweight structure of the battery connection assembly 800, which is beneficial to reducing the overall weight of the battery cooling device 010 and making it easier to carry the battery cooling device 010.

[0087] Optionally, the first side plate 830 and the second side plate 840 have the same structure and shape; this can reduce mold investment and improve the assembly and production efficiency of the battery connection assembly 800. The structure of the first side plate 830 will be used as an example for an exemplary description.

[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, forming a roughly L-shaped structure. The second plate 832 is connected to the support member 821. The first plate 831 and the second side plate 840 are located opposite each other, and a receiving space 801 is formed therebetween. This arrangement ensures the stability of the battery connection assembly 800.

[0089] The first plate 831 and the second plate 832 are connected in an integral manner, and the angle between the two is 90°.

[0090] Of course, in other embodiments, the first plate 831 and the second plate 832 may be connected by welding, connection via fasteners such as bolts, etc., and the angle between the two may be 88°, 93°, etc., which is 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 of 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 connecting member 820 at the same time; in this way, the number of bolts used can be reduced, thereby lowering costs.

[0093] Please refer to Figure 1 、 Figure 3 and Figure 4 In this embodiment, one 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 one end of the first plate 831 of the other first side plate 830 away from the second plate 832 is detachably connected to the atomizer box 200; such a configuration can ensure the assembly stability of the liquid storage tank 100 and the atomizer box 200 when the battery cooling device 010 is used to cool the battery placed in the accommodating space 801, and can smoothly detach the liquid storage tank 100 and the atomizer box 200 from the corresponding first side plate 830 when transporting and packaging the battery cooling device 010, and then store the liquid storage tank 100 and the atomizer box 200 in the accommodating space 801.

[0094] Furthermore, one end of the first plate 831 of one of the first side plates 830, which is away from the second plate 832, is detachably connected to the liquid storage tank 100 via bolts, and one end of the first plate 831 of the other first side plate 830, which is away from the second plate 832, is also detachably connected to the atomizer box 200 via bolts. Of course, in other embodiments, one end of the first plate 831 of one of the first side plates 830, which is away from the second plate 832, can also be detachably connected to the liquid storage tank 100 via a snap-fit ​​connection, and one end of the first plate 831 of the other first side plate 830, which is away from the second plate 832, can also be detachably connected to the atomizer box 200 via a snap-fit ​​connection, which is not specifically limited herein.

[0095] Alternatively, see Figure 4 and Figure 5, one 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 one end of the first plate 831 of one first side plate 830 away from the second plate 832 can abut against the liquid storage tank 100, and the limiting rib 833 connected to one end of the first plate 831 of the other first side plate 830 away from the second plate 832 can abut against the atomizer box 200; in this way, when the liquid storage tank 100 and the atomizer box 200 are moved out of the accommodating 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 and the liquid storage tank 100 and the atomizer box 200 to ensure the accuracy of assembly.

[0096] Alternatively, see 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 generally L-shaped, with the second plate 832 connected to the fourth plate 823, and the first plate 831 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 are also connected to the connector 820. The connection method between the first plate 831 and the third plate 822 is similar to the connection method between the second plate 832 and the fourth plate 823, and will not be repeated here.

[0098] Furthermore, the support member 821 further 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 in an integral manner, and the angle between them is 90°.

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

[0101] Alternatively, see Figure 1 and Figure 3 The battery connection assembly 800 also includes a charging plug 850, which is connected to the connector 820. The charging plug 850 is connected to the charging device. The connection methods include but are not limited to detachable connection (for example, plug-in) and fixed connection. When the battery is set in the accommodating 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 battery can be charged by the charging device.

[0102] Optionally, the atomizer 300 can be electrically connected to a charging device via a charging plug 850, that is, the charging device can be used to power the atomizer 300. Alternatively, in other embodiments, the atomizer 300 can be directly electrically connected to another power source, which is not specifically limited here.

[0103] Alternatively, see Figure 3 The battery connection assembly 800 also includes a pedal 860. The pedal 860 and the connector 820 are spaced apart in the vertical direction. One end of the pedal 860 is connected to one of the support members 821 and the second plate 832 of the lower first side plate 830 by bolts, and the other end of the pedal 860 is connected to another support member 821 and the second plate 832 of the lower second side plate 840 by bolts. The setting of the pedal 860 can support the entire battery cooling device 010. At the same time, since the battery cooling device 010 has a relatively light structure, in order to avoid lifting the battery cooling device 010 when pulling out the battery in the storage space 801, the worker can step on the supporting pedal 860 plate and then pull out the battery. Moreover, when the battery or the atomizer box 200 and the liquid storage tank 100 are placed in the storage space 801, the pedal 860 can also support the battery or the atomizer box 200. The specific structure of the pedal 860 is similar to that of the related art and will not be repeated here.

[0104] It should be understood that in other embodiments, the footrest 860 can also 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 can also be welding, etc., which is 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 used as an example for exemplary description.

[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 correspond to the two first slots 834 one by one and can be removably plugged in. This arrangement ensures that the guide member 810 is easy to install and remove.

[0107] Furthermore, the first plate 831 has a mating surface 835, and the first plate 831 is connected to two first ribs 836, the two first ribs 836 are opposite and spaced apart, and each first rib 836 is spaced apart with the mating surface 835 to form a first slot 834; both ends of the guide member 810 are provided with a mating portion 811, and the mating portion 811 includes two second ribs 812, the second ribs 812 are connected to the guide member 810, and the two second ribs 812 of each mating portion 811 are spaced apart to form a second slot 813; the two mating portions 811 are plugged into and mated with the two first slots 834 in a one-to-one correspondence, specifically, one of the second ribs 812 of each mating portion 811 is plugged into the corresponding first slot 834, and the first rib 836 on the corresponding side is plugged into the second slot 813, and the other second rib 812 is overlapped on the side of the corresponding first rib 836 facing away from the first slot 834, and the guide member 810 is in contact with the mating surface 835. With such a setting, a snap-fit ​​structure can be formed between the guide member 810 and the first plate 831 to improve the problem that the guide member 810 is easily separated from the first plate 831 in a direction perpendicular to the mating surface 835 and in a direction from one of the first slots 834 to the other first slot 834, thereby ensuring the reliability of the guide member 810 being assembled in the accommodating space 801.

[0108] Optionally, the first rib 836 is adapted to the width of the second slot 813 , and the second rib 812 is adapted to the width of the first slot 834 ; such an arrangement can improve the situation where the conductive member is connected to the first plate 831 and shakes.

[0109] Furthermore, the guide member 810 is also detachably connected to the first plate 831 by bolts to further improve the stability of the guide member 810 when assembled in the accommodating space 801, and to improve the problem that the guide member 810 is prone to accidentally sliding off the first plate 831 in the up and down directions.

[0110] It should be understood that in other embodiments, the guide member 810 may be detachably connected to the first plate 831 only by bolts, which is not specifically limited herein.

[0111] Please refer to Figure 2 、 Figure 7 and Figure 8The battery cooling device 010 of this embodiment further includes an opening and closing component 400, which is disposed at the liquid outlet 120 and is 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 liquid 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 liquid storage chamber 110 does not pass through the liquid outlet 120, and thus cannot be replenished in the atomizing chamber 210. By providing the opening and closing component 400, the liquid in the liquid storage chamber 110 can be replenished into the atomizing chamber 210 as needed, thereby facilitating the atomizer 300 disposed in the atomizing chamber 210 to be maintained at an optimal liquid level, i.e., enabling the atomizer 300 to operate at an optimal liquid level, thereby ensuring that the atomizer 300 reliably forms mist droplets, i.e., ensuring that the battery cooling device 010 maintains a stable mist output, thereby 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 arranged at the liquid outlet 120. The float 410 is rotatably arranged in the atomizing chamber 210 and is 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 the action of its own weight to enable the valve 420 to open the liquid outlet 120. When the liquid level in the atomizing chamber 210 reaches a second preset liquid level, the float 410 is reset 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 liquid outlet 120 can be automatically opened or closed according to the liquid level in the atomizing chamber 210, so that the atomizer 300 always operates under the optimal atomizing liquid level condition. That is, when the liquid level in the atomizer 300 decreases, the float 410 can drive the valve 420 to realize the automatic water replenishment mechanism to maintain the liquid level height in the atomizer 300, which can ensure that the atomizer 300 is always below a certain liquid level and ensure a stable and sufficient amount of mist output.

[0113] Further, please refer to Figure 9The valve 420 includes a valve body 421 and an elastic member 422. The valve body 421 is movably disposed at the liquid outlet 120 for opening or closing the liquid outlet 120. The elastic member 422 is configured to elastically cooperate with the valve body 421. The float 410 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 410 rotates under the action of its own weight, 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 410 returns to its original position under the action of buoyancy, and the valve body 421 returns to its original position under the elastic force of the elastic member 422 to close the liquid outlet 120. The provision of the elastic member 422 ensures that the valve body 421 can be reliably driven to close the liquid outlet 120 when the liquid level in the atomizer 300 rises.

[0114] It should be understood that the valve 420 can be a one-way valve. When the one-way valve is not pushed by the float 410, the valve body outlet is closed, that is, the path for the liquid to flow from the liquid storage chamber 110 to the atomization chamber 210 is blocked. The float 410 is required to push the valve core upward to open the valve body outlet, thereby opening the path for the liquid to flow from the liquid storage chamber 110 to the atomization chamber 210.

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

[0116] Alternatively, the elastic member 422 may be a spring or an elastic sleeve, etc., which is not specifically limited herein. The elastic member 422 may be connected between the valve body 421 and the liquid storage tank 100, or between the valve body 421 and the atomization box 200, which is not specifically limited herein.

[0117] Optionally, the float 410 includes a float body 411 and a pusher 412 connected to an 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 within the atomizing chamber 210 reaches a first preset level, the float body 411 rotates under its own weight and drives 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 within the atomizing chamber 210 reaches a second preset level, the float body 411, under the action of buoyancy, drives the pusher 412 out of the return trajectory of the valve body 421. The valve body 421 is reset under the elastic force of the elastic member 422 and closes the liquid outlet 120. The provision of the pusher 412 can reliably push 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 opposite to each other, the rotation axis of the float 410 is located between the first end and the second end, and the first end is in transmission cooperation with the valve 420 to open or close the liquid outlet 120; the distance from the first end to the rotation axis is smaller than the distance from the second end to the rotation axis; specifically, the float body 411 has a first end and a second end opposite to each other, the rotation axis of the float body 411 is located between the first end and the second end, and the first end is connected to the pusher 412; when the liquid level in the atomizing chamber 210 reaches the first preset liquid level, the float body 411 is moved under its own weight. 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 the buoyancy force, and causes the first end of the float body 411 to rotate downward to drive the pusher 412 to exit the reset track of the valve body 421. The valve body 421 is reset 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 opening and closing of the liquid outlet 120 .

[0120] It should be noted that in order to ensure the sensitivity of the float 410 in rotating 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 atomization chamber 210. For example, when the liquid in the atomization 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 facing away from the liquid storage tank 100 , and the liquid in the atomization 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 disposed within 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. The support base 220 supports the float body 411, ensuring that the float body 411 rotates smoothly within the atomizing chamber 210.

[0123] Furthermore, two spaced support seats 220 are provided in the atomizing chamber 210. The support seats 220 are provided with grooves 221. Specifically, a groove 221 with an open top is provided on the side of one support seat 220 facing the other support seat 220. The battery cooling device 010 also includes a fixing member 230. The two ends of the rotating shaft 413 are rotatably inserted into the grooves 221 of the two support seats 220. The fixing member 230 is connected to at least one of the two support seats 220 and prevents the rotating shaft 413 from detaching from the grooves 221. This arrangement can ensure that the float 410 is rotatably provided in the atomizing chamber 210 for easy operation.

[0124] Furthermore, a first avoidance space 222 is formed between the two support seats 220, and a second avoidance space 231 is provided on the side of the fixing frame facing the first avoidance space 222. The first avoidance space 222 and the second avoidance space 231 are both used to avoid the float 410; such a setting can prevent the float 410 from being interfered with by the support seat 220 or the fixing member 230 when rotating.

[0125] The connection methods between the fixing member 230 and the support base 220 include but are not limited to connection with fasteners such as bolts, clamping, and bonding.

[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 in 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; wherein, 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 the action of its own weight and causes 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 is reset under the action of buoyancy and causes 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 and closing component 400 can also be a solenoid valve arranged at the liquid outlet 120, and the battery cooling device 010 also includes a liquid level sensor, which is arranged in the atomization chamber 210 and is connected (communicates) 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 a 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 a 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 of this embodiment further includes a mist channel 500 and a mist outlet 501 connected to the mist channel 500. The mist channel 500 is also connected to the atomizing chamber 210, so that the mist droplets in the atomizing chamber 210 are drained through the mist channel 500 and then discharged from the mist outlet 501. This arrangement ensures that the mist droplets formed in the atomizing chamber 210 are reliably discharged through the mist channel 500 and the mist outlet 501, thereby reliably using 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 expanded channel, and the inner diameter of the second channel 520 at the end closest to the first channel 510 is smaller than the inner diameter of the second channel 520 away from the first channel 510. The expanded second channel 520 enables mist droplets to be output more evenly from the mist outlet 501, thereby utilizing more uniform mist droplets to efficiently, reliably, and evenly cool the battery.

[0130] Optionally, the inner diameter of the second channel 520 gradually increases from the end close to the first channel 510 to the end away from the first channel 510, so that the second channel 520 is roughly shaped like a flared trumpet. This configuration can make the mist droplets more evenly output through the guidance of the second channel 520.

[0131] Furthermore, the inner diameter of the first channel 510 is smaller than or equal to the inner diameter of the end of the second channel 520 connected to the first channel 510. This allows the first channel 510, with its smaller inner diameter, to concentrate the mist droplets formed in the atomization chamber 210, ensuring smoother and faster mist discharge and improving vortex flow. It also reduces the 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 chamber 210, so that the mist droplets in the atomizing chamber 210 can be concentrated and output from the atomizing chamber 210 through the first channel 510. Since the first channel 510 is set relatively narrow, it can guide and output the mist droplets formed in the atomizing chamber 210 in a concentrated manner, thereby helping to improve the problem of the mist droplets not being evenly dispersed and output due to the action of the airflow, and improving the uniformity and stability of the heat dissipation of the battery by mist.

[0133] The inner diameter of the first channel 510 being narrower than the width of the atomizing chamber 210 may mean that, when the first channel 510 and the atomizing chamber 210 are orthographically projected onto 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 chamber 210 in any direction on the horizontal plane. This can also be understood as the area of ​​the orthographic projection of the first channel 510 on the horizontal plane being smaller than the area of ​​the orthographic projection of the atomizing chamber 210 on the horizontal plane.

[0134] Alternatively, see Figure 1 and Figure 12 A diverter rib 521 is further provided in the second channel 520. The diverter rib 521 is used to disperse the mist entering the second channel 520 from the first channel 510 to improve the uniformity of the mist.

[0135] The specific number of the diverter ribs 521 can be selected according to needs, for example: one, two, three, four, five, etc., which is not specifically limited here.

[0136] In some embodiments, a plurality of diverter ribs 521 (two or more) are provided in the second channel 520, and the distance between any two diverter ribs 521 gradually increases from the end closest to the first channel 510 to the end farther from the first channel 510. This arrangement can improve the uniform dispersion of the mist and ensure uniform output of the mist from the mist outlet 501.

[0137] Optionally, the first channel 510 and the second channel 520 are arranged in sequence along the up-down direction, and the first channel 510 is located below the second channel 520; such an arrangement can reliably guide the droplets in the atomization chamber 210 located below the liquid storage tank 100 upward to ensure that the droplets can more comprehensively cover the battery, thereby improving the heat dissipation effect of the battery.

[0138] Optionally, the mist channel 500 is provided in the liquid storage tank 100 and distributed on a side of the liquid storage tank 100 facing the accommodating space 801. This arrangement can make the structure of the battery cooling device 010 more compact, which is conducive to reducing the overall volume of the battery cooling device 010.

[0139] Furthermore, the mist passage 500 is integrally formed with the liquid storage tank 100. Of course, in other embodiments, the mist passage 500 can also be provided on the liquid storage tank 100 by bonding, clamping, 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 air flow 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 arranged at the air flow channel 600 and is used to blow the mist droplets entering the air flow channel 600 out of the air flow channel 600 and allow the mist droplets to enter the storage space 801 along with the air flow. The provision of the fan 700 can, on the one hand, more reliably blow the droplets toward the battery, and on the other hand, can simultaneously use the airflow of the fan 700 to cool the battery. This achieves a combination of rapid vaporization of the water mist and airflow, maximizing the heat absorption efficiency and allowing the battery to be cooled quickly in a short period of time.

[0141] Furthermore, when the liquid storage tank 100 and the atomizer box 200 are moved out of the storage space 801, the air flow channel 600 is arranged opposite the storage space 801, the fan 700 is located at the opening of the air flow channel 600 at one end away from the storage space 801, and the mist outlet 501 is closer to the storage space 801 relative to the fan 700. This arrangement can more reliably blow mist droplets toward the battery placed in the storage space 801, thereby improving the battery cooling efficiency.

[0142] Optionally, the liquid storage tank 100 is an annular cavity structure, and the liquid storage tank 100 surrounds and defines the air flow channel 600, that is, the liquid storage cavity 110 of the liquid storage tank 100 surrounds the air flow channel 600; please refer to Figure 1 、 Figure 12 and Figure 13The second channel 520 and the diverter rib 521 disposed therein both extend into the airflow channel 600. Along the axial direction of the airflow channel 600, one end of the second channel 520 forms an air inlet 522, and the other end forms a mist outlet 501 connected to the air inlet 522. The mist outlet 501 faces the storage space 801. This arrangement ensures that the air blown by the fan 700 is reliably directed from the air inlet 522 to the mist outlet 501, efficiently directing the airflow and mist droplets into the storage space 801. This improves the battery cooling efficiency and ensures a compact structural design for the liquid storage tank 100, thereby ensuring the overall miniaturization of the battery cooling device 010.

[0143] Optionally, the fan 700 can be electrically connected to a charging device via a charging plug 850, that is, the charging device can be used to power the fan 700. Alternatively, in other embodiments, the fan 700 can be directly electrically connected to another power source, which is not specifically limited here.

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

[0145] Furthermore, the rectifying member 710 has a plurality of air holes 711 distributed in an array. This arrangement enables the air blown by the fan 700 to be output from the plurality of air holes 711 distributed in an array, thereby reliably converting the rotating airflow into multiple straight and uniform airflows, ensuring a good rectifying effect, that is, ensuring the uniformity of the air output and improving the uniformity of heat dissipation of the battery.

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

[0147] Furthermore, the second channel 520 has an air outlet at one 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 part of the airflow rectified by the rectifying component 710 is blown into the second channel 520 through the air inlet 522, and then blown out from the mist outlet 501 and enters the accommodation space 801, and another part of the airflow rectified by the rectifying component 710 is blown through the gap between the second channel 520 and the top of the airflow channel 600 to bring the mist droplets output from the second channel 520 from the air outlet into the accommodation space 801.

[0148] It should be understood that in other embodiments, the mist outlet 501 can also be set on the bottom wall of the air flow channel 600 and connected to the air flow channel 600, that is, the second air duct and the diverter rib 521 set in the second air duct do not extend into the air flow channel 600; in the up and down direction, the fan 700 and the rectifying member 710 are both located above the mist outlet 501, and both ends of the air flow channel 600 have openings. The fan 700 is arranged near one of the openings, and the mist outlet 501 is distributed near the other opening. The airflow blown out by the fan 700 is rectified by the rectifying member 710 and blows through the mist outlet 501, and then blows into the accommodating space 801 from the opening of the air flow channel 600 away from the fan 700. The airflow rectified into a straight airflow by the rectifying member 710 is blown above the mist outlet 501, and can be mixed with the mist droplets that have become uniform after being guided by the second channel 520 and blown toward the battery, thereby improving the cooling efficiency of the battery.

[0149] Optionally, the liquid storage tank 100 is connected to a support rib 610 , and the support rib 610 is located in the air flow channel 600 , and the fan 700 and the fairing 710 are connected to the support rib 610 through fasteners.

[0150] Furthermore, the airflow channel 600 is provided with a plurality of support ribs 610, which are spaced apart circumferentially around the airflow channel 600. The fan 700 and the fairing 710 are connected to the support ribs 610 in a one-to-one correspondence via a plurality of fasteners. This arrangement ensures the stability of the fan 700 and the fairing 710 in the airflow channel 600 and prevents the support ribs 610 from interfering with the airflow of the fan 700, thereby ensuring good heat dissipation for the battery.

[0151] Optionally, the outer peripheral wall of the fairing 710 abuts against the inner wall of the airflow channel 600 to improve the problem of air leakage between the outer periphery of the fairing 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 rectifying member 710 and the inner wall of the air flow channel 600, which is not specifically limited here.

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

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

[0155] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
