DETAILED DESCRIPTION

[0026] The scheme of the embodiment of the present application is described in detail below in conjunction with the drawings of the specification.

[0027] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

All directional indications (such as up, down, left, right, front, back...) in the embodiments of this application are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0030] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] The embodiments of the present disclosure provide a cooling device for transportation, which is used to cool transportation, or even extinguish fires. For example, the cooling device is used to cool components (such as batteries, or brake discs) on the chassis of transportation, that is, the cooling device is pushed in from under the chassis of the transportation to cool the components on the chassis. The transportation can be a car, a motorcycle, etc. For example, the car can be a new energy vehicle.

[0032] See also Figure 1 to Figure 9 The cooling device includes a diverter 2, a rotating component 7 and a cooling component 1.

[0033] The flow divider 2 has a chamber 23, an inlet 21 and an outlet 22; the inlet 21 and the outlet 22 are both connected to the chamber 23. The flow divider 2 is a flat structure so as to be easily extended under the chassis of the car.

[0034] In some examples, the side of the diverter 2 is provided with an outlet 22 and an inlet 21. The number of inlets 21 may be one or more (e.g., two). The number of outlets 22 may be one or more (e.g., two, or five). The number of sides of the diverter 2 is six, and five outlets 22 are respectively located on five sides, and all the inlets 21 are located on the remaining side. The inlet 21 may be connected to an external device, for example, the inlet 21 is connected to the external device through a joint. The external device can provide a cooling medium with a certain pressure or flow rate, and the cooling medium enters the chamber through the inlet 21. The cooling medium may be at least one of a gas, a liquid, and a powder. For example, the cooling medium may be a liquid (e.g., water, a coolant, etc.). For another example, the cooling medium may be a gas (e.g., nitrogen, nitrogen dioxide, etc.). For example, the cooling medium may be a mixture of firefighting foam and nitrogen.

[0035] The top surface of the diverter 2 is provided with a handle 5 to facilitate lifting the diverter 2. The bottom surface of the diverter 2 is provided with a second moving wheel 6. The second moving wheel 6 can be a directional wheel and / or a universal wheel.

[0036] The material of the diverter 2 can be metal or its alloy, for example, the metal can be copper, iron, aluminum, etc. For example, the material of the diverter 2 is aluminum or aluminum alloy, so that the diverter 2 is light in weight, so that the user can easily push the cooling device.

[0037] The rotating assembly 7 includes a rotating shaft 72 and a plurality of blades 71; the rotating shaft 72 is rotatably arranged in the chamber; a plurality of blades 71 are arranged on the rotating shaft 72 and are distributed in a circular array; and the blades 71 are located in the chamber. In this way, the cooling medium enters the chamber from the inlet 21 and hits the blades 71, so that the blades 71 drive the rotating shaft 72 to rotate, thereby causing the blades 71 and the rotating shaft 72 to rotate as a whole. For example, the rotating shaft 72 is rotatably arranged in the diverter 2 through a bearing and is located in the chamber 23. The mechanical structure of the rotating shaft 72 and the blades 71 simplifies the structure of the rotating assembly 7 and reduces the failure of the rotating assembly 7.

[0038] The cooling component 1 includes a shunt pipe 11 and a spray head 12. The shunt pipe 11 is connected to the outlet 22. The spray head 12 is arranged on the shunt pipe 11 and is used to spray a cooling medium. In this way, the cooling medium in the chamber flows into the shunt pipe 11 and is sprayed out through the spray head 12, so that the temperature of transportation can be reduced by the cooling medium sprayed by the cooling component 1. For example, the shunt pipe 11 is connected to the outlet 22 through a joint, and the joint can be a quick joint or a common joint. The spray head 12 can be a common spray head 12 or an electric spray head 12. The number of the shunt pipes 11 can be one or more.

[0039] In some examples, the shunt tube 11 is detachably connected to the outlet 22, and the number of outlets 22 and shunt tubes 11 can be multiple. When in use, the shunt tube 11 can be connected to each outlet 22; or, the shunt tube 11 can be connected to a part of the outlets 22, and the other part of the outlets 22 can be blocked. For example, the outlet 22 is self-sealed by a quick connector, or the outlet 22 is blocked by a plug.

[0040] Two embodiments of the cooling component 1 are exemplified below.

[0041] The first embodiment of the cooling assembly 1 is shown below.

[0042] The shunt pipe 11 is a first hard pipe; the number of the first hard pipe and the outlet 22 are both multiple and the same; the multiple first hard pipes are arranged in one-to-one correspondence with the multiple outlets 22. In this way, the cooling medium sprayed out by the cooling component 1 can be made larger in area, and the temperature can be reduced quickly. The material of the first hard pipe is a hard material (i.e., a non-flexible material), for example, it can be a metal (such as iron, aluminum), hard plastic, etc. At least one (for example, one, or more than one) spray head 12 is arranged on each first hard pipe.

[0043] The cooling assembly 1 further includes a support plate 4 and a push rod 3. The support plate 4 may include two foldable sub-support plates 41. The support plate 4 may also be an integral structure. This article takes the example that the support plate 4 may include two foldable sub-support plates 41 for explanation.

[0044] The open end of the first hard tube is detachably connected to the outlet 22, and the first hard tube is arranged on the first board surface 43 of the sub-support plate 41; when the two sub-support plates 41 are in the folding device, the second board surfaces 44 of the two sub-support plates 41 are opposite. In this way, the support plate 4 and the diverter 2 can be connected into a whole by using the first hard tube, so as to facilitate user use. The first hard tube can be removed from the diverter 2 to facilitate the folding of the two sub-support plates 41. In addition, it can also prevent the first hard tube from being damaged after the two sub-support plates 41 are folded. Among them, the first board surface 43 and the second board surface 44 are relative board surfaces. The first hard tube and the sub-support plate 41 can be fixedly connected or detachably connected.

[0045] Since the two sub-support plates 41 can be folded, the two sub-support plates 41 can have a folded state and an unfolded state. In the folded state, the two sub-support plates 41 are folded in half along the folded portion; for example, after folding, the two sub-support plates 41 are parallel. In the unfolded state, the two sub-support plates 41 are unfolded along the folded portion, for example, after unfolding, the two sub-support plates 41 are located in the same plane.

[0046] In some examples, the two sub-support plates 41 are connected by a hinge 42. The two sub-support plates 41 are in a folded state, and the two sub-support plates 41 overlap (referring to completely overlap). Of course, the two sub-support plates 41 can also be connected by a rotating shaft 72 or the like.

[0047] Part of the multiple first hard tubes is located on one support plate 4, and the other part is located on another support plate 4. In some examples, one of the multiple outlets 22 (which can be called the middle outlet 22) is arranged opposite to the folding part of the two sub-support plates 41; the remaining outlets 22 (that is, the remaining outlets 22 except the middle outlet 22) are evenly divided along the folding part of the two sub-support plates 41 and are symmetrically arranged. In this way, after the outlets 22 are connected to the first hard tubes, the first hard tubes can be distributed more evenly; when the user uses it, the force is more evenly applied, which is easy to master. For example, there are five outlets 22, and there are two outlets 22 on each side of the middle outlet 22.

[0048] In some examples, the cooling assembly 1 further includes a buffer pad 83 and a first moving wheel 8; the buffer pad 83 is disposed on the second plate surface 44 of the sub-support plate 41, and the first moving wheel 8 is retractably disposed on the second plate surface 44 of the sub-support plate 41; wherein, the two sub-support plates 41 are in a folded state, the first moving wheel 8 is retracted, the buffer pads 83 on the two sub-support plates 41 are in contact, and the two sub-support plates 41 are parallel; the two sub-support plates 41 are in an unfolded state, the two sub-support plates 41 are in the same plane, and the first moving wheel 8 is extended for movement. In this way, the retractable first moving wheel 8 can make the folding angle of the two sub-support plates 41 smaller and occupy less space; it is also convenient to move in the unfolded state. The buffer pad 83 can reduce the friction between the two folded sub-support plates 41.

[0049] For example, the first movable wheel 8 may include a fixed wheel 82 and a universal wheel 81; the universal wheel 81 is a retractable universal wheel 81 (for example, an elastic universal wheel 81, or the universal wheel 81 is connected to the sub-support plate 41 via a spring). In this way, after the two sub-support plates 41 are folded, the retractable universal wheel 81 is squeezed and retracted.

[0050] The sub-support plate 41 is provided with a mounting hole 84, and the directional wheel 82 is folded and arranged in the mounting hole 84. After the two sub-support plates 41 are folded, the directional wheel 82 is folded in the mounting hole 84. After the two sub-support plates 41 are unfolded, the directional wheel 82 comes out from the mounting hole 84 for movement. The folding direction of the directional wheel 82 is the same as the folding direction of the two sub-support plates 41, so as to prevent the directional wheel 82 from folding into the mounting hole 84 during movement. Of course, the state of the directional wheel 82 can be kept unchanged by the locking member when locking. For example, the locking member can be a pin, and the pin can support the folding part of the universal wheel 81.

[0051] The directional wheel 82 is close to the end of the sub-support plate 41, and the universal wheel 81 is close to the folding part of the two sub-support plates 41; the buffer pad 83 is located between the directional wheel 82 and the universal wheel 81, and the buffer pad 83 is close to the directional wheel 82. In order to facilitate the universal wheel 81 to change direction, the directional wheel 82 moves. The directional wheel 82 and the universal wheel 81 are prior art.

[0052] The push rod 3 is detachably connected to the diverter 2. In this way, when in use, the push rod 3 can be connected to the diverter 2, so that the user can operate the push rod 3 to push the diverter 2 to move. When not in use, such as during transportation, the push rod 3 and the diverter 2 can be disassembled to facilitate transportation and reduce occupied space. The material of the push rod 3 can be metal or hard plastic.

[0053] The push rod 3 includes a connecting rod 32, a fixed rod 33, an extension rod 34 and two snap rings 31; the outlet 22 is provided with a joint, and the two snap rings 31 are snapped on two coaxial joints among the multiple joints; the two ends of the connecting rod are fixedly connected to the two snap rings 31; one end of the fixed rod 33 is fixedly connected to the connecting rod 32, and the other end is detachably connected to the extension rod 34. In this way, the push rod 3 is detachably connected to the diverter 2 by using the joint, making the structure simple and ingenious. When in use, the snap ring 31 can be snapped on the joint; when not in use, the snap ring 31 can be removed from the joint. The extension rod 34 can keep the user away from the transportation vehicle to ensure the user's safety. The inlet can be located between the two snap rings 31.

[0054] A second embodiment of the temperature reduction device is shown below.

[0055] The shunt pipe 11 may include a second hard pipe and a connecting pipe; the cooling device also includes a fire hook 9; one end of the connecting pipe is detachably connected to the outlet 22, and the other end is detachably connected to one end of the second hard pipe; the fire hook 9 and the sprinkler head 12 are both arranged on the other end of the second hard pipe, and the sprinkler head 12 is connected to the other end of the second hard pipe. In this way, the fire hook 9 can be used to remove obstacles so that the sprinkler head 12 can spray better. The fire hook 9 cooperates with the sprinkler head 12 to form a curtain barrier, which can effectively reduce the harm of heat radiation to users. The sprinkler head 12 can be one or more.

[0056] The connecting pipe can be a fire hose, that is, after a certain pressure of water flows into the fire hose, the hardness of the fire hose is high and it is not easy to deform. The connecting pipe can also be a hard pipe.

[0057] The description of the embodiment of the cooling assembly 1 is complete.

[0058] When using the cooling device, the cooling component 1 and the diverter 2 are assembled, and the diverter 2 is connected to the external equipment. When the cooling component 1 is pushed under the chassis of the vehicle, the external equipment (such as a fire pump, a water pump, etc.) is turned on, so that the sprinkler head 12 sprays a cooling medium (such as mist water) to cool the battery of the vehicle and even to insulate heat. Since the cooling device is a flat and compact structure, the cooling device is light in weight and easy to transport and carry.

[0059] The above description is only an implementation method of the present application, and does not limit the patent protection scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
