Description

Technical Field

[0001] The present application relates to the technical field of battery heat dissipation, and in particular to a fan assembly, a power supply device, and a method for manufacturing the power supply device. Background Art

[0002] In engineering applications, many pieces of equipment include heat-generating components, such as power supplies and large computer chassis. These components are housed within a component compartment. During operation, these components generate heat, which needs to be dissipated from the compartment to ensure operation within a preset operating temperature range. The equipment also includes an air duct, which carries cool air. A fan assembly connects the duct to the component compartment, promoting the flow of cool air through the duct and dissipating the heat generated by the components.

[0003] During the actual assembly process of engineering equipment, there are installation errors between the component bin and the air duct. The relative positions of the air outlet of the air duct and the air inlet of the component bin deviate, making it impossible for the two ends of the fan assembly to be sealed and connected to the component bin and the air duct. This not only leads to air volume loss, but also fails to effectively cool the heating components, reducing the overall heat dissipation performance of the engineering equipment. Summary of the Invention

[0016] This form is not only easy to assemble, but also can circumferentially and sealingly fix the second end of the flexible connecting sleeve to the second mounting member through the second fixing ring, avoiding air leakage caused by loosening of the second end of the flexible connecting sleeve during use.

[0017] According to some embodiments of the present application, the first mounting member includes a first substrate and a first connecting member. The first opening is provided on the first substrate. The first connecting member is disposed on a side of the first substrate facing the flexible connecting sleeve. The first connecting member surrounds the first opening, and the first end of the flexible connecting sleeve is sleeved on the first connecting member.

[0018] By providing the first connecting member and using the outer peripheral side of the first connecting member to fit with the first end of the flexible connecting sleeve, the first connecting member can be hermetically connected to the circumferential side of the first end of the flexible connecting sleeve. By providing the first substrate, it is convenient to connect to the component bin through the first substrate.

[0019] According to some embodiments of the present application, the first mounting member includes a first sub-substrate, a second sub-substrate, and a first connecting member. The first connecting member forms the first opening. The first sub-substrate and the second sub-substrate are symmetrically disposed with respect to the first connecting member. The first end of the flexible connecting sleeve is sleeved on the first connecting member.

[0020] By providing the first connecting member and using the outer peripheral side of the first connecting member to fit with the first end of the flexible connecting sleeve, the first connecting member can be hermetically connected to the circumferential side of the first end of the flexible connecting sleeve. By symmetrically disposing the first sub-substrate and the second sub-substrate with respect to the first connecting member, it is convenient to connect to the component bin through the first sub-substrate and the second sub-substrate, and the weight of the first mounting member can also be reduced.

[0021] According to some embodiments of the present application, the second mounting member includes a second substrate and a second connecting member. The second opening is provided on the second substrate. The second connecting member is disposed on a side of the second substrate facing the flexible connecting sleeve. The second connecting member surrounds the second opening, and the second end of the flexible connecting sleeve is sleeved on the second connecting member.

[0022] By providing the second connecting member and using the outer peripheral side of the second connecting member to fit with the second end of the flexible connecting sleeve, the second connecting member can be hermetically connected to the circumferential side of the second end of the flexible connecting sleeve. By providing the second substrate, it is convenient to connect to the component bin through the second substrate.

[0023] According to some embodiments of the present application, the blower is fixed to a side of the second substrate facing the flexible connecting sleeve. The second connecting member surrounds the blower, and a wire passing hole for the wire harness of the blower to pass through is provided on the second connecting member.

[0024] A wire hole is provided on the second connecting member, and the wiring harness of the fan passes through the wire hole. The end of the wiring harness is exposed to the outside of the fan assembly and is connected to the external power supply and control unit. When multiple fan assemblies are used, the layout design of the wiring harness of the fan when connected to the external power supply and control unit can be simplified.

[0025] According to some embodiments of the present application, the fan assembly further includes: a cover plate, which is arranged opposite to the second substrate, and the cover plate is fixed to the fan, and is used to limit the wiring harness of the fan between the cover plate and the second substrate.

[0026] According to some embodiments of the present application, the fan is fixed to the second mounting member. Fixing the fan to the second mounting member allows the fan to be as close to the second opening as possible, thereby increasing the wind speed at the second opening of the fan assembly. By increasing the wind speed of the fan assembly, the wind output efficiency of the fan assembly can be improved, prompting cold air to blow into the interior of the component compartment, increasing the effective cooling area, and fully cooling the heating components. In addition, the wiring harness is limited between the cover plate and the second base plate to prevent the wiring harness from being entangled in the fan.

[0027] According to some embodiments of the present application, the flexible connecting sleeve is made of cloth or resin material, is soft in texture, can be flexibly deformed, has good wear resistance, is thick and airtight, and can prevent cold air from seeping through the flexible connecting sleeve.

[0028] An embodiment of the present application also proposes a power supply device, which includes: a box; a battery storage device for storing batteries, the battery storage device being installed in the box, and the battery storage device being provided with an air inlet; an air duct being installed in the box, and the air duct being provided with an air outlet; the above-mentioned fan assembly, the first mounting member being installed in the air duct so that the first opening is connected to the air outlet, and the second mounting member being installed in the battery storage device so that the second opening is connected to the air inlet.

[0029] Using the above-mentioned fan assembly to connect the air outlet of the air duct with the air inlet of the battery storage device can adapt to the relative position deviation between the air inlet and the air outlet caused by installation errors when the air duct and the battery storage device are assembled in the box, thereby avoiding air leakage and ensuring good heat dissipation consistency of the battery storage device in the power supply equipment.

[0030] According to some embodiments of the present application, the air duct includes an air duct body and a guide assembly, the air outlet is arranged on the air duct body, the guide assembly is fixed to the air duct body, and the guide assembly is used to guide the first mounting part to slide along the extension direction of the guide assembly so that the air outlet is connected to the first opening.

[0031] By providing a guiding component on the air duct body, it is possible to guide the first mounting member to slide along the extending direction of the guiding component, thereby ensuring the relative position between the first mounting member and the air duct, facilitating the connection of the air outlet to the first opening, and ensuring the sealed connection between the fan assembly and the air duct.

[0032] According to some embodiments of the present application, the power supply device further includes: a third fixing member. A fifth mounting hole is provided on the first mounting member, and a sixth mounting hole is provided on the air duct. The third fixing member is configured to pass through the fifth mounting hole to connect with the sixth mounting hole, thereby fixing the first mounting member to the air duct; the air duct further includes a mating portion, and the first mounting member further includes a limiting portion. The limiting portion is used to abut against the mating portion to limit the sliding of the first mounting member along the guiding component. The limiting portion is configured such that when the limiting portion abuts against the mating portion, the fifth mounting hole is aligned with the sixth mounting hole.

[0033] By abutting the limiting portion against the mating portion, the position of the first mounting member relative to the air duct can be positioned, facilitating the worker to connect the first mounting member to the air duct using the first fixing member, so as to improve the circumferential sealing performance between the first mounting member and the air duct.

[0034] According to some embodiments of the present application, the power supply device further includes: a sealing member, which is provided between the second mounting member and the battery storage device and surrounds the air inlet to achieve a sealed connection between the second mounting member and the battery storage device.

[0035] Through the sealing member, the circumference of the second opening can be sealed, preventing cold air from leaking from the gap between the second mounting member and the battery storage device, thus avoiding cold loss and ensuring the consistent heat dissipation of the battery storage device.

[0036] The embodiments of the present application also propose a manufacturing method for a power supply device. The manufacturing method of the power supply device includes:

[0037] Providing a box body;

[0038] Providing a battery storage device for storing batteries, and the battery storage device is provided with an air inlet;

[0039] Providing an air duct, and the air duct is provided with an air outlet;

[0040] Providing a fan assembly, the fan assembly includes:

[0048] By deforming the flexible connecting sleeve to adapt to the change in the relative position between the first mounting member and the second mounting member, it is possible to maintain the circumferential sealing of the air inlet and the air outlet even when there are installation errors between the battery storage device and the air duct. This not only avoids the loss of air volume caused by air leakage but also ensures the heat dissipation consistency of the battery storage device in the power supply equipment.

Detailed implementation mode

[0067] The following further describes the implementation mode of the present application in detail in combination with the drawings and embodiments. The following detailed description of the embodiments and the drawings are used to exemplarily illustrate the principle of the present application, but cannot be used to limit the scope of the present application, that is, the present application is not limited to the described embodiments.

[0068] In the description of the present application, it should be noted that unless otherwise specified, the meaning of "a plurality of" is more than two; the orientation or position relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. "Vertical" is not strictly vertical, but within the allowable error range. "Parallel" is not strictly parallel, but within the allowable error range.

[0069] The orientation terms used in the following description are all the directions shown in the figures, and do not limit the specific structure of the present application. In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0070] In the related art, an engineering device includes a component bin, an air duct, and a cold air device. A heating element is arranged in the component bin, and the heating element generates heat during operation. The air duct includes a cold air inlet and an air outlet. The cold air inlet is connected to the cold air device, and the air outlet is connected to the component bin through a conventional fan assembly. The cold air device inputs cold air into the air duct, and the conventional fan assembly promotes the cold air to enter the component bin, and the heat generated by the heating element during operation is taken away by the cold air.

[0071] However, in the actual assembly process of the engineering device, there are inevitably installation errors between the component bin and the air duct, resulting in a deviation in the relative position between the air outlet of the air duct and the air inlet of the component bin. Since the conventional fan assembly is a rigid structure, it is difficult to ensure that both ends of the fan assembly are hermetically connected to the air outlet and the air inlet when there is a deviation in the actual relative position between the air outlet and the air inlet, and air leakage is likely to occur. The air intake volume at the air inlet of the component bin is less than the air outlet volume of the air duct, and the cold air leaks from the connection between the fan assembly and the component bin and the air duct. This not only causes cold air loss, but also reduces the heat dissipation consistency of the component bin.

[0072] Based on the above problems, an embodiment of the present application proposes a new type of fan assembly, which is installed between the air duct and the component bin of the engineering device. The new type of fan assembly can adapt to the relative position deviation between the air outlet of the air duct and the component bin, so that it can still be hermetically connected to the air outlet and the air inlet when there is a relative position deviation between the air outlet and the air inlet, so that there is no air leakage at the connection between the new type of fan assembly and the component bin and the air duct.

[0073] In some embodiments of the present application, the engineering device is a power supply device, and the heating element is a battery, and the battery generates heat during operation.

[0074] In other embodiments, the engineering device can also be a large computer case, and the heating element can be a chip. Further, the engineering device can also include a temperature control element, and the hot air sent out in the air duct is used to maintain the temperature control element in the component bin operating at a sufficiently high temperature by supplying hot air into the component bin.

[0075] Taking a power supply device 1 as an example, the specific structure of the fan assembly in the embodiments of the present application and its connection relationship with other devices will be specifically described below.

[0076] Figure 1 and Figure 2 The figures respectively show an axonometric schematic diagram of a partial structure and a front-view structural schematic diagram of a power supply device 1 disclosed in the embodiments of the present application.

[0077] As Figure 1 and Figure 2 As shown in the figures, the power supply device 1 includes a box body 10, a battery storage device 20, an air duct 30, a fan assembly 40, and a cold air device 50. The battery storage device 20 is used to store batteries, and the battery storage device 20 and the air duct 30 are installed inside the box body 10. The battery storage device 20 is provided with an air inlet 211. The air duct 30 extends along the direction m. The air duct 30 includes a cold air inlet 311 and an air outlet 312. The cold air inlet 311 is connected to the cold air device 50. The cold air output by the cold air device 50 enters the air duct 30 through the cold air inlet 311 and is conveyed along the direction m. The fan assembly 40 connects the air outlet 312 and the air inlet 211 to introduce the cold air in the air duct 30 into the interior of the battery storage device 20 along the direction n to cool the batteries stored in the battery storage device 20.

[0078] In the embodiments of the present application, the directions m, q, and n are respectively the length, width, and height directions of the power supply device 1 disclosed in the embodiments of the present application.

[0079] The cold air device 50 can be arranged inside the box body to reasonably utilize the space inside the box body. With the cold air device 50 built in under the condition of the limited volume of the box body, the power supply device 1 has a compact structure.

[0080] In other embodiments, the cold air device 50 can also be arranged outside the box body, and the air duct 30 and the cold air device 50 are connected outside the box body.

[0081] Figure 1 The figure shows an axonometric schematic diagram of a partial structure of a power supply device 1 disclosed in the embodiments of the present application. As Figure 1 shown, an installation frame 21 is provided on one side of the battery storage device 20 close to the air duct 30. The installation frame 21 is provided with an air inlet 211 communicating with the interior of the battery storage device 20. The cold air enters the interior of the battery storage device 20 through the air inlet 211 to cool the batteries stored in the battery storage device 20. The battery storage device 20 is also provided with a ventilation opening 212. The cold air enters the battery storage device 20 to cool the batteries and then leaves the battery storage device 20 through the ventilation opening 212 to take away the heat dissipated by the batteries during the power supply process.

[0082] As Figure 1 and Figure 2As shown, the ventilation opening 212 and the air inlet 211 can be arranged at two opposite ends of the battery storage device 20 along the direction n, so as to guide the cold air to enter the battery storage device 20 from the air inlet 211 along the direction n and then continue to flow along the direction n, passing through a plurality of batteries and taking away the heat dissipated by the batteries during the power supply process. The cold quantity carried by the cold air can be fully utilized, and thus a better cooling effect can be achieved under the same cold air volume.

[0083] In other embodiments, the ventilation opening 212 can also be arranged on the side wall of the battery storage device 20. The battery storage device 20 includes a first end and a second end opposite to each other along the direction n, and the side wall refers to the wall body between the first end and the second end of the battery storage device 20.

[0084] Figure 2 Shown is a schematic structural diagram of a partial structure of a power supply device 1 disclosed in an embodiment of the present application from a front view perspective. As Figure 2 shown, an air outlet 312 is provided on one side of the air duct 30 close to the battery storage device 20, and the air outlet 312 and the air inlet 211 are arranged opposite to each other along the direction n. By using the fan assembly 40 to connect the air outlet 312 and the air inlet 211, the cold air in the air duct 30 can be promoted to enter the battery storage device 20 along the direction n to cool the batteries placed in the battery storage device 20.

[0085] Figure 3 and Figure 4 Shown are respectively schematic structural diagrams of the air duct 30 of the power supply device 1 in an embodiment of the present application from a front view perspective and a bottom view perspective.

[0086] As Figure 2 、 Figure 3 and Figure 4 shown, the air duct 30 extends along the direction m and blows air along the direction m. A plurality of air outlets 312 are provided, and the plurality of air outlets 312 are arranged at intervals along the direction m. Correspondingly, a plurality of air inlets 211 are provided on one side of the battery storage device 20 close to the air duct 30, and the air inlets 211 correspond to the air outlets 312 one by one. Each air outlet 312 is connected to the corresponding air inlet 211 through a fan assembly 40. The cold air in the air duct 30 enters the corresponding air inlet 211 from each air outlet 312 along the direction n, and multiple strands of cold air jointly cool the batteries stored in the battery storage device 20.

[0087] The fan assembly 40 in the embodiment of the present application is connected between the air duct 30 and the battery storage device 20. The fan assembly 40 can adapt to the relative position deviation between the air outlet 312 of the air duct 30 and the air inlet 211 of the battery storage device 20, so as to still be hermetically connected to the air outlet 312 and the air inlet 211 when there is a relative position deviation between the air outlet 312 and the air inlet 211.

[0088] Figure 5 Shown is a schematic structural diagram of the battery storage device 20 in the power supply device 1 disclosed in the embodiments of the present application from a top-down perspective.

[0089] As Figure 5 shown, in some embodiments of the present application, a plurality of battery units 22 are stored at intervals along the direction m in the battery storage device 20, and each battery unit 22 includes a plurality of batteries. Each battery unit 22 is arranged between two adjacent air inlets 211, and each air inlet 211 is arranged between two adjacent battery units 22. In this way, it is possible to blow cold air from both sides of each battery unit 22 to the battery unit 22, and each battery in the battery unit 22 can be cooled, avoiding the phenomenon that the batteries located on the side far from the air inlet 211 cannot be blown by the cold air due to mutual occlusion of the batteries, and improving the heat dissipation uniformity of the battery storage device 20.

[0090] In other embodiments, only one battery may be arranged inside the battery storage device 20, and a stream of cold air is sent in through each air inlet 211 to cool the battery sufficiently and evenly.

[0091] Figure 6 and Figure 7 Shown are respectively schematic structural diagrams of the fan assembly 40 disclosed in the embodiments of the present application from a top-down perspective and a bottom-up perspective. As Figure 6 and Figure 7 shown, the fan assembly 40 includes a first mounting member 41, a second mounting member 42, a flexible connecting sleeve 43, and a fan 44. The two ends of the flexible connecting sleeve 43 are respectively a first end 431 and a second end 432. The first end 431 is connected to the first mounting member 41, the second end 432 is connected to the second mounting member 42, and the fan 44 is arranged inside the flexible connecting sleeve 43.

[0092] The flexible connecting sleeve 43 is made of a deformable material and can flexibly connect the first mounting member 41 and the second mounting member 42 through the first end 431 and the second end 432 to allow the relative positions of the first mounting member 41 and the second mounting member 42 to change, thereby adapting to the position deviation generated during the assembly of the air duct 30 and the battery storage device 20.

[0093] In some embodiments of the present application, the material of the flexible connecting sleeve 43 is cloth or resin material. It is not only soft in texture and can deform flexibly to allow the relative positions of the first mounting member 41 and the second mounting member 42 to change, but also has a high surface density, which can avoid the loss of cold air caused by the cold air leaking through the flexible connecting sleeve 43.

[0094] For example, the flexible connecting sleeve 43 can be a rubber sleeve, which can not only achieve flexible deformation but also has good elasticity, so as to further allow a greater positional deviation between the first mounting member 41 and the second mounting member 42 through stretching deformation.

[0095] Figure 6 and Figure 7 The structural schematic diagrams of the top view and bottom view perspectives of the fan assembly disclosed in the embodiments of the present application are shown respectively. As Figure 6 and Figure 7 shown, the first mounting member 41 is provided with a first opening 413, the second mounting member 42 is provided with a second opening 423, and the flexible connecting sleeve 43 is configured to communicate the first opening 413 and the second opening 423. Gas enters the interior of the fan assembly 40 from the first opening 413 and exits the fan assembly 40 from the second opening 423. The fan 44 promotes the gas to flow along the direction n inside the flexible connecting sleeve 43, so as to urge the gas to flow from the first opening 413 to the second opening 423.

[0096] In some embodiments of the present application, two fans 44 are provided. The cross-section of the flexible connecting sleeve 43 (i.e., the plane perpendicular to the direction n) is rectangular, and the two fans 44 are arranged at intervals along the length direction of the air inlet cross-section of the rectangle, so as to uniformly promote the gas to flow in the flexible connecting sleeve 43. Correspondingly, as Figure 7 shown, two second openings 423 are also provided, and the air outlet side 444 of each fan 44 corresponds to one second opening 423.

[0097] In other embodiments, the number and arrangement of the fans 44 can be flexibly arranged according to the shape of the air inlet and outlet cross-sections of the fan assembly 40, so as to make the air outlet of the fan assembly 40 uniform. For example, the air inlet and outlet cross-section of the fan assembly 40 is square, four fans 44 are provided, and the four fans 44 are evenly arranged in a square array inside the flexible connecting sleeve 43 and are located on the same plane parallel to the air inlet and outlet cross-section of the fan assembly 40. For another example, the air inlet and outlet cross-section of the fan assembly 40 is circular, six fans 44 are provided, and the six fans 44 are evenly arranged in a circular array inside the flexible connecting sleeve 43 and are located on the same plane parallel to the air inlet and outlet cross-section of the fan assembly 40. For another example, the air inlet and outlet cross-section of the fan assembly 40 is a regular polygon or circular, one fan 44 is provided, and one fan 44 is centrally arranged inside the flexible connecting sleeve 43.

[0098] The fan 44 is fixed on the second mounting member 42, which can make the fan 44 as close as possible to the air inlet 211 of the battery storage device 20 (please refer to Figure 5 ), thereby increasing the wind speed at the air inlet 211, urging the cold air to blow into the interior of the battery storage device 20, increasing the effective cooling area, and cooling a larger number of batteries.

[0099] In other embodiments, the fan 44 may also be fixed to the first mounting member 41 to promote airflow near the first opening 413 along the direction n. For another example, the fan 44 may be disposed in the area between the first mounting member 41 and the second mounting member 42 via an additional bracket to promote balanced air flow.

[0100] Figure 8 What is shown is an exploded view of a fan assembly 40 disclosed in an embodiment of the present application. The specific structural form of the fan assembly 40 is exemplified in detail below.

[0101] like Figure 8 As shown, in some embodiments of the present application, the fan assembly 40 includes a first fixing ring 45 for fixing the first end 431 of the flexible connecting sleeve 43 to the first mounting member 41, the first end 431 is sleeved on the first mounting member 41, and the first fixing ring 45 is sleeved on the first end 431.

[0102] This form has a simple structure and is easy to assemble. On the basis of the first end 431 of the flexible connecting sleeve 43 being sleeved on the first mounting member 41, the first fixing ring 45 can be further sleeved on the first end 431, thereby realizing the circumferential sealing of the first end 431, so that the first end 431 is sealed and connected to the circumferential side of the first mounting member 41, avoiding the formation of gaps at the junction of the first end 431 and the first mounting member 41, thereby avoiding air leakage.

[0103] The first fixing ring 45 can be a rigid component, such as a plastic ring or a metal ring. When the first fixing ring 45 is sleeved onto the first end 431 of the flexible connecting sleeve 43, and the first end 431 is sleeved onto the first mounting member 41, the first fixing ring 45 and the first mounting member 41 jointly clamp the first end 431 to achieve a circumferential seal around the first end 431. Furthermore, the first fixing ring 45 is easily assembled with the first mounting member 41, resulting in a simple, secure, and reliable assembly.

[0104] In other embodiments, the first end 431 of the flexible connecting sleeve 43 can be connected to the first mounting member 41 by other methods. For example, the opening of the first end 431 of the flexible connecting sleeve 43 can be circumferentially expandable and elastic. After the opening of the first end 431 is stretched open, it is placed on the first mounting member 41. The opening of the first end 431 contracts circumferentially under its own elasticity and is tightly placed on the first mounting member 41. Alternatively, a circle of glue is applied to the inner edge of the first end 431 to bond the first end 431 to the first mounting member 41.

[0105] Further, the fan assembly 40 further includes a first fixing member 481. A first mounting hole 451 is provided on the first fixing ring 45, and a second mounting hole 4311 is provided at the first end 431 of the flexible connection sleeve 43. The first fixing member 481 is configured to pass through the first mounting hole 451 and the second mounting hole 4311 to be connected to the first mounting member 41, thereby fixing the first end 431 to the first mounting member 41.

[0106] This form is not only easy to assemble, but also can circumferentially and sealingly fix the first end 431 of the flexible connection sleeve 43 to the first mounting member 41 through the first fixing ring 45, preventing the first end 431 from loosening during use and causing air leakage.

[0107] For example, the first fixing member 481 can be a screw. A threaded hole corresponding to the first mounting hole 451 is provided on the first mounting member 41, and the first fixing member 481 is in threaded cooperation with the threaded hole.

[0108] For another example, the first fixing member 481 can be a rivet to rivet the first fixing ring 45 and the first mounting member 41.

[0109] In other embodiments, the first end 431 can also be circumferentially and sealingly connected to the first mounting member 41 by means of wire winding, cloth strip winding, rubber band winding, etc.

[0110] As Figure 8 shown, in some embodiments of the present application, the first mounting member 41 includes a first substrate 411 and a first connecting member 412. A first opening 413 is provided on the first substrate 411. The first connecting member 412 is disposed on the side of the first substrate 411 facing the flexible connection sleeve 43. The first connecting member 412 is disposed around the first opening 413, and the first end 431 of the flexible connection sleeve 43 is sleeved on the first connecting member 412.

[0111] Specifically, the two opposite sides of the first substrate 411 along the direction n are respectively a first side 4111 of the first substrate and a second side 4112 of the first substrate. Among them, the first connecting member 412 is installed on the second side 4112 of the first substrate. The first opening 413 is a hole on the first mounting member 41. In some embodiments of the present application, the first opening 413 is a hole penetrating the first substrate 411 along the direction n. The first connecting member 412 is disposed around the first opening 413. It can be understood that the first substrate 411 can be an integral structure or a spliced - formed structure, and the number of the first connecting members 412 surrounding the first opening 413 can be one or more. For example, when the number of the first connecting members 412 is one, the first connecting member 412 can be arranged as an annular structure and disposed around the first opening 413. For another example, when the number of the first connecting members 412 is multiple, the first connecting members 412 can be spaced around the first opening 413.

[0112] By providing the first connecting member 412, the outer peripheral side of the first connecting member 412 is circumferentially attached to the first end 431 of the flexible connecting sleeve 43, and the first fixing ring 45 and the first connecting member 412 jointly clamp the first end 431 to achieve circumferential sealing of the first end 431; by providing the first substrate 411, the first mounting member 41 can have a sufficient area for assembling with other components.

[0113] Figure 9 Shown is a schematic structural view of a first mounting member 41 in another form of a fan assembly 40 disclosed in an embodiment of the present application, schematically showing a specific structural form of the first mounting member 41 in another form.

[0114] As Figure 9 shown, in other embodiments, the first opening 413 is a hole formed in the first connecting member 412. The first mounting member 41 includes a first sub-substrate 415, a second sub-substrate 416, and a first connecting member 412. The first connecting member 412 is formed with a first opening 413, and the first sub-substrate 415 and the second sub-substrate 416 are symmetrically arranged with respect to the first connecting member 412. By providing the first sub-substrate 415 and the second sub-substrate 416 that are symmetrically arranged with respect to the first connecting member 412, not only does the first mounting member 41 have a sufficient mounting area, but also the weight of the first mounting member 41 can be reduced, thereby reducing the total weight of the fan assembly 40 and facilitating the installation of the fan assembly 40.

[0115] Alternatively, the first mounting member 41 may also include three or four sub-substrates, and the four sub-substrates are arranged around the first opening 413 of the first connecting member 412.

[0116] Furthermore, the first mounting member 41 may be in other forms. For example, it may be a sleeve structure or a perforated plate-like structure, and can also be connected to the first end 431 of the flexible connecting sleeve 43, and the first opening 413 is communicated with the flexible connecting sleeve 43.

[0117] Please refer to Figure 8 again. The fan assembly 40 further includes a second fixing ring 46 for fixing the second end 432 of the flexible connecting sleeve 43 to the second mounting member 42. The second end 432 of the flexible connecting sleeve 43 is sleeved on the second mounting member 42, and the second fixing ring 46 is sleeved on the second end 432 of the flexible connecting sleeve 43.

[0118] Among them, the second fixing ring 46 may be a rigid component, such as a plastic ring, a metal ring, etc. When the second fixing ring 46 is sleeved on the second end 432 of the flexible connecting sleeve 43 and the second end 432 is sleeved on the second mounting member 42, on the one hand, the second fixing ring 46 and the second mounting member 42 jointly clamp the second end 432 to achieve circumferential sealing of the second end 432; on the other hand, the second fixing ring 46 is easy to assemble with the second mounting member 42, and the assembly is simple, firm and reliable.

[0119] In other embodiments, the second end 432 of the flexible connection sleeve 43 can also be connected to the second mounting member 42 in other ways. For example, the opening of the second end 432 of the flexible connection sleeve 43 is circumferentially expandable and elastic. After the opening of the second end 432 is expanded, it is sleeved on the second mounting member 42, and the opening of the second end 432 circumferentially contracts under its own elasticity and is tightly sleeved on the second mounting member 42; or a circle of glue is applied to the inner edge of the second end 432 to bond the second end 432 to the second mounting member 42, etc.

[0120] The fan assembly 40 further includes a second fixing member 482. The second fixing ring 46 is provided with a third mounting hole 461, and the second end 432 of the flexible connection sleeve 43 is provided with a fourth mounting hole 4321. The second fixing member 482 is configured to pass through the third mounting hole 461 and the fourth mounting hole 4321 to be connected to the second mounting member 42, so as to fix the second end 432 of the flexible connection sleeve 43 to the second mounting member 42.

[0121] This form is not only easy to assemble, but also can circumferentially and sealingly fix the second end 432 of the flexible connection sleeve 43 to the second mounting member 42 through the second fixing ring 46, avoiding air leakage caused by loosening of the second end 432 during use.

[0122] For example, the second fixing member 482 can be a screw. The second mounting member 42 is provided with a threaded hole corresponding to the third mounting hole 461, and the second fixing member 482 is in threaded cooperation with the threaded hole.

[0123] For another example, the second fixing member 482 can be a rivet to rivet the second fixing ring 46 and the second mounting member 42.

[0124] In other embodiments, the second end 432 can also be circumferentially and sealingly connected to the second mounting member 42 by means of wire winding, cloth strip winding, rubber band winding, etc.

[0125] Figure 8 Shown is an exploded view of a fan assembly 40 disclosed in an embodiment of the present application. As Figure 8 shown, the second mounting member 42 includes a second base plate 421 and a second connecting member 422. The second base plate 421 is provided with a second opening 423 (please refer to Figure 7 ), the second connecting member 422 is arranged on the side of the second base plate 421 facing the flexible connection sleeve 43, the second connecting member 422 is arranged around the second opening 423, and the second end 432 of the flexible connection sleeve 43 is sleeved on the second connecting member 422.

[0126] Specifically, the two sides of the second substrate 421 along the thickness direction are respectively the first side 4211 of the second substrate and the second side 4212 of the second substrate. Among them, the first side 4211 of the second substrate is the side facing the flexible connection sleeve 43, the second connecting member 422 is installed on the first side 4211 of the second substrate, and the second side 4212 of the second substrate is used to connect with other components.

[0127] By providing the second connecting member 422, the outer peripheral side of the second connecting member 422 is circumferentially attached to the second end 432 of the flexible connection sleeve 43, and the second fixing ring 46 and the second connecting member 422 jointly clamp the second end 432 to achieve the circumferential sealing of the second end 432; by providing the second substrate 421, the second mounting member 42 can have a sufficient area to be assembled with other components.

[0128] In other embodiments, the second mounting member 42 can also be in other forms, such as a sleeve structure or a plate-like structure with holes, and can also be connected to the second end 432 of the flexible connection sleeve 43, and the second opening 423 is connected to the flexible connection sleeve 43.

[0129] Figure 8 Shown is an exploded view of a fan assembly 40 disclosed in an embodiment of the present application, as Figure 8 shown. Further, the power supply device 1 further includes a seal 60, and the seal 60 is disposed on the second side 4212 of the second substrate of the second mounting member 42 to achieve a sealed connection between the second mounting member 42 and other components.

[0130] Specifically, the seal 60 is disposed on the second side 4212 of the second substrate, and a through hole for avoiding the second opening 423 (please refer to Figure 7 ) is provided on the seal 60.

[0131] Through the seal 60, the circumferential side of the second opening 423 can be sealed, avoiding the side leakage of cold air from the installation gap between the second substrate 421 and other components and causing cold loss.

[0132] For example, the seal 60 is a rubber plate. In other embodiments, the seal 60 can also be made of other materials with waterproof performance and elasticity, such as a silicone gasket.

[0133] Figure 8 Shown is an exploded view of a fan assembly 40 disclosed in an embodiment of the present application, as Figure 8As shown in the figure, the blower 44 is fixed to the first side 4211 of the second substrate. The second connecting member 422 is disposed around the blower 44, and a wire passing hole 424 for the wire harness 442 to pass through is provided on the second connecting member 422. Correspondingly, through holes corresponding to the wire passing hole 424 are also provided on the second fixing ring 46 and the second end 432 of the flexible connecting sleeve 43. The wire harness 442 passes through the wire passing hole 424, the flexible connecting sleeve 43, and the second fixing ring 46 and then extends out of the blower assembly 40.

[0134] As Figure 8 shown in the figure, long through holes 4413 are provided at the four corners of the blower body 441. The power supply device 1 further includes a fourth fixing member 483. The blower body 441 is firmly connected to the second substrate 421 by passing the fourth fixing member 483 through the long through holes 4413, so as to prevent the blower 44 from loosening during long-term rotation and separating from the second substrate 421. For example, the fourth fixing member 483 is a screw or a bolt.

[0135] On the one hand, the blower 44 is fixed to the second mounting member 42. On the other hand, a wire passing hole 424 is provided on the second connecting member 422. The wire harness 442 passes through the wire passing hole 424, and the end of the wire harness 442 is exposed outside the blower assembly 40 and connected to an external power supply and a control unit. When multiple blower assemblies 40 are used, the layout design of the connection between the wire harness 442 and the external power supply and the control unit can be simplified.

[0136] Figure 10 The figure shows a vertical sectional schematic view of the blower assembly 40 disclosed in the embodiment of the present application. The specific structural form of the blower 44 will be specifically described below.

[0137] As Figure 10 shown in the figure, the blower 44 is disposed inside the flexible connecting sleeve 43, and is used to promote the flow of gas from the first opening 413 to the second opening 423, so as to promote the air outlet speed of the blower assembly 40. The blower 44 includes a blower body 441 and a wire harness 442 (please refer to Figure 8 ). The blower body 441 includes a blower housing 4411 and blades 4412 installed inside the blower housing 4411. The blower 44 is an axial flow blower. The air inlet and outlet directions of the blower 44 extend along the direction n. The blower 44 includes an air inlet side 443 and an air outlet side 444 along the direction n. One end of the wire harness 442 is connected to the blower body 441, and the other end extends outside the blower 44 to connect the blower body 441 to an external control unit and a power supply.

[0138] Please continue to refer to Figure 8 and Figure 10 , optionally, the blower assembly 40 further includes a cover plate 47. The cover plate 47 and the second substrate 421 are disposed on both sides of the blower 44 along the direction n. The cover plate 47 is fixed to the blower 44 and is used to limit the wire harness 442 between the cover plate 47 and the second substrate 421.

[0139] Specifically, a cover plate opening 472 for exposing the air inlet side 443 of the fan 44 is provided on the cover plate 47. A wire harness cavity 471 can be jointly enclosed by the second substrate 421, the cover plate 47, and the flexible connection sleeve 43. The wire harness cavity 471 is not in communication with either the air inlet side 443 or the air outlet side 444 of the fan 44. After passing through the wire harness cavity 471, the wire harness 442 leaves the wire harness cavity 471 through the wire passing hole 424 to be connected to an external power supply and a control unit. During the operation of the fan 44, the wire harness 442 will not be drawn into the interior of the fan 44 from the air inlet side 443 and the air outlet side 444, thus ensuring the safe operation of the fan 44.

[0140] Figure 11 Shown is an assembly schematic diagram of a fan assembly 40 and an air duct 30 disclosed in an embodiment of the present application.

[0141] As Figure 11 shown, the first mounting member 41 of the fan assembly 40 is connected to the air duct 30, so that the air outlet 312 of the air duct 30 is in communication with the fan assembly 40. The air duct 30 includes an air duct body 31 and a guiding assembly 32. The air outlet 312 is provided on the air duct body 31. The guiding assembly 32 is fixed to the air duct body 31 and extends along the direction q. The guiding assembly 32 is used to guide the first mounting member 41 to slide along the direction q, so that the air outlet 312 is in communication with the first opening 413 (please refer to Figure 10 ), ensuring a sealed connection between the fan assembly 40 and the air duct 30.

[0142] As Figure 11 shown, in some embodiments of the present application, the guiding assembly 32 includes a first guiding member 321 and a second guiding member 322, and both the first guiding member 321 and the second guiding member 322 extend along the direction q. The air outlet 312 is provided on the air duct body 31. The first guiding member 321 and the second guiding member 322 are fixed to the air duct body 31 and are located on opposite sides of the air outlet 312. The first mounting member 41 is inserted between the first guiding member 321 and the second guiding member 322 along the direction q. The two opposite sides of the first substrate 411 along the direction m are respectively the third side 4113 and the fourth side 4114 of the first substrate. The third side 4113 of the first substrate is in sliding fit with the first guiding member 321, and the fourth side 4114 of the first substrate is in sliding fit with the second guiding member 322.

[0143] By providing the first guiding member 321 and the second guiding member 322, the fan assembly 40 can be guided to be inserted between the first guiding member 321 and the second guiding member 322 along the direction q, thereby positioning the relative position of the fan assembly 40 and the air duct body 31, and avoiding air leakage at the connection between the fan assembly 40 and the air duct body 31 due to relative position deviation.

[0144] Optionally, both the first guiding member 321 and the second guiding member 322 are slot structures, which further limit the blower assembly 40 to be parallel to the side wall of the air duct body 31 where the air outlet 312 is provided while guiding the blower assembly 40 to slide in the direction q, so as to reduce the installation gap between the blower assembly 40 and the air duct body 31 and further improve the circumferential sealing performance of the connection between the blower assembly 40 and the air duct 30.

[0145] In other embodiments, the guiding assembly 32 may also include one guiding member extending in the direction q. The guiding member is fixed to the air duct body 31 and is slidably engaged with one of the third side 4113 or the fourth side 4114 of the first substrate to guide the blower assembly 40 to slide in the direction q, simplifying the structure of the guiding assembly 32.

[0146] Please continue to refer to Figure 11 , a plurality of sixth mounting holes 313 are further provided on the side wall of the air duct 30 where the air outlet 312 is provided. The plurality of sixth mounting holes 313 are located between the first guiding member 321 and the second guiding member 322 and are arranged close to the air outlet 312. The sixth mounting holes 313 are used for mounting the blower assembly 40. The power supply device 1 further includes a third fixing member (not shown in the figure). A fifth mounting hole 4115 is provided on the first mounting member 41. The third fixing member is configured to pass through the fifth mounting hole 4115 to be connected to the sixth mounting hole 313 of the air duct 30, thereby fixing the first mounting member 41 to the air duct 30.

[0147] Further, three fifth mounting holes 4115 are provided. The three fifth mounting holes 4115 are arranged at intervals in the direction m on the first substrate 411 and are located at the rear end of the first substrate 411 in the direction q. In this way, the fifth mounting holes 4115 are arranged close to the assembly operation side of the worker, which is convenient for the worker to use the third fixing member to fix the first mounting member 41 to the air duct 30.

[0148] The third fixing member is similar to the above-mentioned first fixing member 481 (please refer to Figure 8 ), and specifically may be a screw or a rivet, which will not be further elaborated here.

[0149] In other embodiments, other forms may also be adopted to connect the first mounting member 41 to the air duct body 31, such as welding or snap connection.

[0150] Further, the first mounting member 41 includes a limiting portion 414, and the air duct 30 includes a cooperating portion 33. The limiting portion 414 is used to abut against the cooperating portion 33 of the air duct 30 to limit the sliding of the first mounting member 41 in the direction q. The limiting portion 414 is configured such that when the limiting portion 414 abuts against the cooperating portion 33, the air outlet 312 of the air duct 30 is aligned with the first opening 413 of the blower assembly 40, thereby ensuring the circumferential sealed connection between the air duct 30 and the blower assembly 40.

[0151] As Figure 11 shown, in some embodiments of the present application, the limiting portion 414 and the mating portion 33 are configured to be inserted along the direction q on the first substrate 411 and abut against the rear end of the guiding assembly 32. The mating portion 33 is located at the outer end of the guiding assembly 32 along the direction q, and the limiting portion 414 is located at the rear end of the first substrate 411 along the direction q. In this way, the outer end of the guiding assembly 32 can be used as the mating portion 33, which simplifies the structure of the air duct 30 and makes it easy to observe whether the mating portion 33 abuts against the limiting portion 414.

[0152] Figure 12 Shown is another form of the assembly schematic diagram of a fan assembly 40 and an air duct 30 disclosed in the embodiments of the present application, indicating another arrangement form of the limiting portion 414 and the mating portion 33.

[0153] As Figure 12 shown, in other embodiments, the limiting portion 414 and the mating portion 33 are configured to be inserted along the direction q on the first substrate 411 and abut against the front end of the guiding assembly 32. The mating portion 33 is located between the first guiding member 321 and the second guiding member 322, and at the inner end of the guiding assembly 32 along the direction q, and the limiting portion 414 is located at the front end of the first substrate 411 along the direction q. In this way, the front end of the first substrate 411 can be used for the limiting portion 414 to abut against the mating portion 33, which simplifies the structure of the fan assembly 40 and is conducive to the manufacturing and forming of the fan assembly 40.

[0154] Figure 13 Shown is the assembly schematic diagram of a fan assembly 40 and a battery storage device 20 disclosed in the embodiments of the present application.

[0155] As Figure 12 shown, a seventh mounting hole 4213 is further provided on the second substrate 421 of the second mounting member 42 of the fan assembly 40 for connecting with the mounting frame 21 of the battery storage device 20.

[0156] As Figure 13 shown, a sealing member 60 is provided between the second substrate 421 and the battery storage device 20 and is arranged around the air inlet 211 to achieve a sealed connection between the second mounting member 42 and the battery storage device 20.

[0157] The power supply device 1 in the embodiments of the present application is described above. Next, the manufacturing method of the power supply device 1 in the embodiments of the present application will be described, and the parts not described in detail can refer to the foregoing embodiments.

[0158] Figure 14 Shown is the step schematic diagram of the manufacturing method of the power supply device 1.

[0159] As Figure 13 shown, the manufacturing method of the power supply device 1 includes:

[0161] S2: Provide the battery storage device 20;

[0162] S3: Provide the air duct 30;

[0163] S4: Provide the fan assembly 40;

[0164] S5: Install the battery storage device 20 and the air duct 30 inside the box body 10;

[0165] S6: Install the first mounting member 41 on the air duct 30 so that the first opening 413 communicates with the air outlet 312;

[0166] S7: Install the second mounting member 42 on the battery storage device 20 so that the second opening 423 communicates with the air inlet 211.

[0167] The implementation order of the steps of the manufacturing method of the above power supply device 1 is not specifically limited, and the implementation order of the steps of the manufacturing method of the above power supply device 1 is not the only implementation order either.

[0168] During the above manufacturing process, there are inevitably installation errors in the step of installing the battery storage device 20 and the air duct 30 inside the box body 10, resulting in a deviation in the relative positions of the air inlet 211 and the air outlet 312. First, install the first mounting member 41 on the air duct 30, and then install the second mounting member 42 on the battery storage device 20. By deforming the flexible connection sleeve 43 to adapt to the change in the relative positions between the first mounting member 41 and the second mounting member 42, it is possible to keep the circumferential sealing performance between the air inlet 211 and the air outlet 312 even when there are installation errors in the battery storage device 20 and the air duct 30. This not only avoids the loss of air volume caused by air leakage but also ensures the heat dissipation performance of the power supply device 1.

[0169] Although the present application has been described with reference to the preferred embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way. The present application is not limited to the specific embodiments disclosed in the text but includes all technical solutions falling within the scope of the claims.
