Description

Technical Field

[0001] This application relates to the field of engines, and more particularly to an engine fan, an engine cooling structure, and an engine. Background Technology

[0002] Engine fans are widely used in mechanical equipment, mainly to cool the engine or provide forced ventilation to ensure the normal operation of the equipment.

[0003] Currently, most engine fans on the market rely on simple mechanical structures to achieve air circulation. Specifically, they typically use a fixed installation method, directly connecting the blades to the motor, and the motor drives the blades to rotate to complete the air delivery task; the motor is usually fixedly connected to the engine housing.

[0004] Regarding the aforementioned technologies, since the motor generates a certain amount of vibration during the rotation of the blades, there is a risk of parts becoming loose or even damaged, which in turn affects the stability and reliability of the entire system. Therefore, providing an engine fan with less vibration to improve engine stability is an urgent problem to be solved. Summary of the Invention

[0005] In order to provide an engine fan with less vibration to improve engine stability, this application provides an engine fan, an engine cooling structure, and an engine.

[0006] In a first aspect, this application provides an engine fan, which adopts the following technical solution:

[0007] An engine fan, comprising:

[0008] Outer frame;

[0009] An inner mounting plate is located inside the outer frame, and a buffer gap is formed between the outer peripheral wall of the inner mounting plate and the inner peripheral wall of the outer frame; the inner mounting plate has a through mounting hole along a first direction, which is perpendicular to the surface of the inner mounting plate.

[0010] An air supply assembly, the air supply assembly being connected to the inner mounting plate; and,

[0011] Vibration damping components, wherein multiple vibration damping components are connected between the outer frame and the inner mounting plate; the vibration damping components include:

[0012] An elastic element, wherein the extension and retraction direction of the elastic element is perpendicular to the first direction, one end of the elastic element is rotatably connected to the outer frame via a first pivot, and the other end is rotatably connected to the inner mounting plate via a second pivot; both the first pivot and the second pivot are parallel to the first direction.

[0013] By adopting the above technical solution, the buffer gap design between the outer frame and the inner mounting plate effectively reduces the rigid contact between them, preventing vibration from being transmitted to the external structure. The air supply assembly is set in the mounting holes of the inner mounting plate, achieving a compact spatial layout. The elastic element in the shock absorption assembly is connected to the outer frame and the inner mounting plate through the first and second rotating shafts respectively, which can absorb the vibration energy generated by the operation of the air supply assembly, thereby significantly reducing the vibration amplitude of the entire engine fan system and its impact on external equipment.

[0014] Optionally, the shock absorption assembly further includes a telescopic rod, one end of which is fixedly connected to the first rotating shaft and the other end of which is fixedly connected to the second rotating shaft, and the telescopic direction of the telescopic rod is parallel to the telescopic direction of the elastic element.

[0015] By adopting the above technical solution, the telescopic rod effectively reduces the bending deformation of the elastic element during operation, improving the overall stability of the shock absorption assembly. Simultaneously, the telescopic rod and the elastic element work together to ensure the smooth movement of the inner mounting plate within the outer frame.

[0016] Optionally, the air supply assembly includes:

[0017] Mounting bracket, the mounting bracket is located inside the mounting hole and is fixedly connected to the inner mounting plate;

[0018] The third rotating shaft is parallel to the first direction and is rotatably connected to the mounting bracket around its own axis;

[0019] A first motor, connected between the third rotating shaft and the mounting bracket, is used to drive the third rotating shaft to rotate along the mounting bracket; and,

[0020] The blade is fixedly connected to the third rotating shaft.

[0021] By adopting the above technical solution, the third rotating shaft is connected to the mounting frame by its own rotation and is driven to rotate by the first motor, thereby driving the blades to rotate synchronously and realizing the effective acceleration and delivery of airflow.

[0022] Optionally, it also includes a dust-blocking assembly, the dust-blocking assembly comprising:

[0023] Multiple rotating columns are parallel to a second direction, and the multiple rotating columns are spaced apart in the second direction, with an exhaust gap formed between two adjacent rotating columns.

[0024] The rotating column is rotatably connected to the rotating column via a fourth rotating shaft, which is parallel to the rotating column.

[0025] The dust-blocking component and the air-supplying component are distributed in a first direction.

[0026] By adopting the above technical solution, multiple rotating columns in the dust-blocking assembly can be spaced apart in the second direction to form an exhaust gap, effectively blocking external dust from entering the engine while ensuring air circulation.

[0027] Optionally, the cross-section of the rotating cylinder along its length direction is polygonal.

[0028] By adopting the above technical solution, the cross-section of the rotating cylinder along its length direction is set as a polygon, which can effectively turbulentize the airflow during the rotation of the cylinder. The turbulent airflow will generate an impact force on the surface of the rotating cylinder, thereby more effectively shaking off the dust attached to the surface of the rotating cylinder, preventing dust accumulation from clogging the air supply gap, and thus ensuring the ventilation performance and working efficiency of the engine fan.

[0029] Optionally, it also includes a transmission assembly, the transmission assembly comprising:

[0030] The first bevel gear is coaxially and fixedly connected to the fourth rotating shaft;

[0031] A drive shaft, parallel to a third direction, rotatably connected to the inner mounting plate about its own axis; and...

[0032] Multiple second bevel gears are coaxially and fixedly connected to the transmission shaft, and each second bevel gear meshes with a corresponding first bevel gear.

[0033] By adopting the above technical solution, the drive shaft, as the core transmission component, can not only effectively transmit power, but also ensure the coordinated movement of all rotating cylinders due to its fixed connection with multiple second bevel gears and the meshing relationship between the second bevel gears and the first bevel gear.

[0034] Optionally, the transmission assembly further includes a second motor connected between the transmission shaft and the inner mounting plate to drive the transmission shaft to rotate along the inner mounting plate.

[0035] By adopting the above technical solution, the second motor is connected between the drive shaft and the inner mounting plate, thereby enabling precise control of the rotation of the drive shaft and driving the entire transmission system to operate.

[0036] Optionally, it also includes a dust collection assembly, the dust collection assembly comprising:

[0037] Velcro; and,

[0038] The brush bristles are connected to the rotating column via the Velcro.

[0039] By adopting the above technical solution, detachable bristles are installed on the side wall of the rotating column. These bristles adsorb dust from the air, effectively reducing the possibility of dust entering the engine. Simultaneously, the Velcro design makes the bristles easy to replace. Furthermore, when the transmission assembly drives the rotating column to rotate, the elastic element, in conjunction with the transmission components, can more thoroughly shake off the dust adhering to the bristles, thus achieving an automatic cleaning function.

[0040] Secondly, this application provides an engine cooling structure, which adopts the following technical solution:

[0041] An engine cooling structure includes the aforementioned engine fan.

[0042] By adopting the above technical solutions, the impact of engine fan vibration on the engine can be reduced.

[0043] Thirdly, this application provides an engine that adopts the following technical solution:

[0044] An engine, including the aforementioned engine cooling structure.

[0045] By adopting the above technical solutions, the impact of vibration on the engine cooling structure can be effectively reduced.

[0046] In summary, this application includes at least one of the following beneficial technical effects:

[0047] The shock absorption assembly, through the cooperation of elastic elements and telescopic rods, effectively supports and absorbs the vibration of the inner mounting plate, reducing the transmission of vibration generated during the operation of the air supply assembly to the external frame, thereby improving the stability and reliability of the entire engine fan.

[0048] The air supply assembly drives the third shaft and blades to rotate via the first motor, which can efficiently accelerate airflow delivery, improve heat dissipation efficiency and reduce energy consumption.

[0049] The dust-blocking component, combined with the transmission component, allows the rotating column to actively remove surface dust, effectively preventing dust from entering the engine and extending the equipment's service life. Attached Figure Description

Detailed Implementation

[0056] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. For ease of description, this application introduces directional terms such as first direction, second direction, and third direction to form a three-dimensional reference direction. The directional terms used, such as "first direction, second direction, and third direction," can be specifically referred to in the figure, where X represents the first direction, Y represents the second direction, Z represents the third direction, and the first direction, second direction, and third direction are perpendicular to each other.

[0057] This application discloses an engine fan. (Refer to...) Figure 1 and Figure 2 The engine fan includes an outer frame 1, an inner mounting plate 2, a shock-absorbing assembly 3, and an air supply assembly 4. The outer frame 1 has a rectangular frame structure, the inner mounting plate 2 is located inside the outer frame 1, and the surface of the inner mounting plate 2 is perpendicular to the first direction. A buffer gap 11 is formed between the outer peripheral wall of the inner mounting plate 2 and the inner peripheral wall of the outer frame 1. Multiple shock-absorbing assemblies 3 are connected between the outer frame 1 and the inner mounting plate 2. Two shock-absorbing assemblies 3 are provided between each side of the outer frame 1 and the shock-absorbing assembly 3. The shock-absorbing assembly 3 includes an elastic element 31 and a telescopic rod 32. The telescopic direction of the elastic element 31 is perpendicular to the first direction. One end of the elastic element 31 is rotatably connected to the outer frame 1 through a first rotating shaft 33, and the other end is rotatably connected to the inner mounting plate 2 through a second rotating shaft 34. Both the first rotating shaft 33 and the second rotating shaft 34 are parallel to the first direction.

[0058] To install the first rotating shaft 33 and the second rotating shaft 34, a first mounting groove 12 is provided on the inner wall of the outer frame 1. The first rotating shaft 33 is located in the first mounting groove 12 and its two ends are rotatably connected to the outer frame 1. A second mounting groove 22 is provided on the outer peripheral wall of the inner mounting plate 2. The second rotating shaft 34 is located in the second mounting groove 22 and its two ends are rotatably connected to the inner mounting plate 2. The first rotating shaft 33 and the second rotating shaft 34 can rotate with the elastic element 31. The dimensions of the first mounting groove 12 and the second mounting groove 22 are adapted to the rotation range of the telescopic rod 32 and the elastic element 31 to prevent the rotation process of the telescopic rod 32 and the elastic element 31 from being interfered with by the outer frame 1 or the inner mounting plate 2. In this disclosure, the elastic element 31 is a compression spring. When the mounting plate is in the middle of the outer frame 1, each elastic element 31 has a preload and is in a compressed state that can recover its deformation and continue to compress, so that the inner mounting plate 2 can swing along a plane perpendicular to the first direction within the outer frame 1.

[0059] To reduce bending of the elastic element 31, one end of the telescopic rod 32 is fixedly connected to the first rotating shaft 33, and the other end is fixedly connected to the second rotating shaft 34. The telescopic direction of the telescopic rod 32 is parallel to the telescopic direction of the elastic element 31, so as to guide the telescopic movement of the elastic element 31.

[0060] Reference Figure 1 and Figure 3 The air supply assembly 4 is mounted on the inner mounting plate 2. Specifically, the inner mounting plate 2 has a mounting hole 21 extending through it along the first direction, and the air supply assembly 4 is located at the mounting hole 21. The air supply assembly 4 includes a mounting bracket 41, a third rotating shaft 42, a first motor 43, and blades 44. The mounting bracket 41 is located inside the mounting hole 21 and is fixedly connected to the inner mounting plate 2. The third rotating shaft 42 is parallel to the first direction and is rotatably connected to the mounting bracket 41 around its own axis. The first motor 43 is connected between the third rotating shaft 42 and the mounting bracket 41 to drive the third rotating shaft 42 along the mounting plate 2. The frame 41 rotates. In this disclosure, the first motor 43 is a servo first motor 43. The housing of the first motor 43 is fixedly connected to the mounting frame 41. The output shaft of the first motor 43 is rotatably connected to the mounting frame 41. After passing through the mounting frame 41, the output shaft of the first motor 43 is coaxially fixedly connected to the third rotating shaft 42, so that the first motor 43 can drive the third rotating shaft 42 to rotate synchronously with the third rotating shaft 42. During use, the first motor 43 drives the third rotating shaft 42 to rotate, thereby driving the blades 44 to rotate and accelerating the airflow.

[0061] Reference Figure 4 and Figure 5In some embodiments of this application, a dust-blocking assembly 5 is further included. The dust-blocking assembly 5 and the air supply assembly 4 are sequentially distributed in a first direction. In the first direction, the dust-blocking assembly 5 is located on the side of the blade 44 away from the first motor 43. The dust-blocking assembly 5 includes a plurality of rotating columns 51. The rotating columns 51 are parallel to the second direction. The plurality of rotating columns 51 are spaced apart in a third direction, and an air supply gap 52 is formed between two adjacent rotating columns 51. The rotating columns 51 are rotatably connected to the inner mounting plate 2 through a fourth rotating shaft 53. The fourth rotating shaft 53 is parallel to the rotating columns 51. In this disclosure, a fourth rotating shaft 53 is fixedly connected to each end of the rotating column 51. The fourth rotating shaft 53 passes through the inner mounting plate 2 and can rotate along the inner mounting plate 2. During the rotation of the rotating column, in conjunction with the shaking of the inner mounting plate 2, the dust on the rotating column 51 can be shaken off, preventing the dust from blocking the air supply gap 52.

[0062] The cross-section of the rotating column 51 along its length direction is polygonal. Preferably, the cross-section of the rotating column 51 along its length direction is rectangular, so that the rotating column 51 can turbulentize the airflow during rotation. The turbulent airflow can then further impact the rotating column 51, shaking off the dust on the surface of the rotating column 51.

[0063] Reference Figure 4 and Figure 5 In order to drive the rotating column 51 to rotate along the inner mounting plate 2, in some embodiments of this application, a transmission assembly 6 is also included. The transmission assembly 6 includes a first bevel gear 61, a transmission shaft 62, a second bevel gear 63, and a second motor 64.

[0064] The fourth shaft 53 at one end of the rotating column 51 passes through the side wall of the inner mounting plate 2 and extends into the buffer gap 11 to connect with the transmission assembly 6. For ease of description, the fourth shaft 53 extending into the buffer gap 11 is named the drive end fourth shaft 53. Multiple drive end fourth shafts 53 are located on the same side of the inner mounting plate 2. A first bevel gear 61 is coaxially fixedly connected to the end of each fourth shaft 53. The first bevel gear 61 and the fourth shaft 53 can rotate synchronously. The end of the first bevel gear 61 with a smaller diameter is located at the end of the drive end fourth shaft 53 away from the rotating column 51.

[0065] The drive shaft 62 is parallel to a third direction. Two lugs 23 are fixedly connected to the outer wall of the inner mounting plate 2. Each end of the drive shaft 62 is provided with a lug 23. The drive shaft 62 is rotatably connected to the lugs 23 around its own central axis. The second bevel gear 63 is coaxially fixedly connected to the drive shaft 62. In this disclosure, there are multiple second bevel gears 63, which are distributed at intervals along a third direction. Each first bevel gear 61 meshes with one of the second bevel gears 63. The housing of the second motor 64 is fixedly connected to one of the lugs 23. The output shaft of the second motor 64 passes through the lug 23 and is coaxially fixedly connected to the drive shaft 62 so that the motor drives the drive shaft 62 to rotate.

[0066] During operation, simply rotate the drive shaft 62, which will drive the second bevel gear 63 to rotate, and then the second bevel gear 63 will drive the first bevel gear 61 and the rotating column 51 to rotate synchronously.

[0067] Reference Figure 4 and Figure 5 In some embodiments of this application, a dust-collecting assembly 7 is also included. The dust-collecting assembly 7 is connected to at least one side wall of the rotating column 51. The dust-collecting assembly 7 includes a connecting strip 71, a Velcro 72, and bristles 73. The connecting strip 71 is fixedly connected to the side wall of the rotating column 51 by screws. When the connecting strip 71 needs to be removed, only the screws need to be removed. The Velcro 72 includes a rounded surface 721 and a hook surface 722. The rounded surface 721 is glued to the connecting strip 71, and the hook surface 722 can be glued to the rounded surface 721. The bristles 73 are fixedly connected to the hook surface 722. During normal use, the bristles 73 can adhere to dust and reduce dust from entering the engine.

[0068] When dust needs to be cleaned, the transmission component 6 drives the cylindrical shaft to rotate, shaking off the dust. In this process, with the help of the elastic element 31, the dust can be shaken off more thoroughly. After long-term use, the bristles 73 can also be replaced. At this time, simply remove the hook side 722 of the Velcro 72 and replace it with a new hook side 722 and bristles 73.

[0069] The implementation principle of an engine fan in this application embodiment is as follows: the inner mounting plate 2 can generate a certain vibration as the air supply assembly 4 rotates, and the elastic element 31 can offset part of the vibration, reducing the overall vibration of the engine caused by the operation of the air supply assembly 4.

[0070] The dust-blocking component 5 reduces the amount of dust entering the engine. When dust needs to be cleaned, the transmission component 6 simply drives the rotating column 51 to rotate, which shakes off the dust.

[0071] This application also discloses an engine cooling structure. The engine cooling structure includes a mounting bracket 41 and the aforementioned engine fan, wherein the outer frame 1 of the engine fan is connected to the mounting bracket 41 by screws.

The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application.
