DETAILED DESCRIPTION

[0039] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0040] Example 1

[0041] like Figure 1-Figure 5As shown, this embodiment provides a fixing device, including a support member 11 and a fixing member 12, wherein the fixing member 12 is connected to the support member 11; the support member 11 includes a bottom plate 111, wherein the bottom plate 111 is provided with a groove 112, wherein the groove 112 is provided with a mounting position 113, wherein the mounting position 113 is used to mount a motor 2 connected with a fan blade 3; the support member 11 also includes a support plate 115, wherein a first end of the support plate 115 is connected to the bottom plate 111; and a second end of the support plate 115 is connected to the fixing member 12.

[0042] The first end of the bottom plate 111 is connected to the fixing member 12, and the second end of the bottom plate 111 is also connected to the fixing member 12. The bottom plate 111 is horizontally arranged close to the motor 2, and the bottom plate 111 is provided with a groove 112, which is adapted to the base 21 of the motor 2, and the size of the groove 112 is the same as the size of the base 21 of the motor 2.

[0043] The motor 2 is placed from top to bottom into the groove 112 of the bottom plate 111, so that the base 21 of the motor 2 is located in the groove 112 of the bottom plate 111, and then the base 21 of the motor 2 is fixed in the groove 112 of the bottom plate 111, thereby fixing the position of the motor 2 and the fan blade 3. Since the groove 112 is provided on the bottom plate 111, the installer does not need to calibrate the gap between the motor 2 and the wind tube 121 to confirm the gap between the fan blade 3 and the wind tube 121, and the installer can quickly install the motor 2 in the groove 112 of the bottom plate 111, thereby improving the installation efficiency of the motor 2.

[0044] The groove 112 is formed on the bottom plate 111 to reduce the vibration generated by the motor 2 during high-speed operation, thereby preventing the motor 2 from being displaced and ensuring that there is a certain gap between the fan blades 3 connected to the motor 2 and the wind tube 121, thereby avoiding friction between the fan blades 3 connected to the motor 2 and the wind tube 121, and preventing the fan blades 3 from being stuck and causing air to be unable to be exhausted.

[0045] The depth of the groove 112 may be 3 mm, or may be other values, which are not limited here. In this embodiment, the depth of the groove 112 is 3 mm as an example.

[0046] The mounting position 113 is arranged at the bottom of the groove 112 , and the mounting position 113 is matched with the mounting structure on the base 21 of the motor 2 . The base 21 of the motor 2 is mounted on the mounting position 113 , thereby fixing the motor 2 and the fan blade 3 .

[0047] A fixing device provided in this embodiment includes a support member 11 and a fixing member 12, and the fixing member 12 is connected to the support member 11; the support member 11 includes a bottom plate 111, and the bottom plate 111 is provided with a groove 112, and the groove 112 is provided with a mounting position 113, and the mounting position 113 is used to install the motor 2 connected with the fan blade 3. The groove 112 on the bottom plate 111 has a smaller height than other positions of the bottom plate 111, that is, the groove 112 on the bottom plate 111 is lower. The motor 2 is installed at the mounting position 113 in the groove 112, which is convenient for the installer to operate, and there is no need to calibrate the gap between the motor 2 and the fixing member 12. The groove 112 is opened on the bottom plate 111, and the bottom plate 111 is sunk. The groove 112 of the bottom plate 111 is provided with a mounting position 113, and the installer can easily install the motor 2 at the mounting position 113, thereby fixing the position of the motor 2. Fixing the position of the motor 2 can prevent the motor 2 and the fan blades 3 from being misaligned, and avoid friction between the fan blades 3 connected to the motor 2 and the fixing member 12 (such as the wind tube 121) during the rotation of the motor 2, so that the fan with the above-mentioned fixing device 1 can exhaust and dissipate heat normally, and the noise during the operation of the fan is relatively small.

[0048] Example 2

[0049] like Figure 1-Figure 5 As shown, this embodiment provides a fixing device, including a support member 11 and a fixing member 12, wherein the fixing member 12 is connected to the support member 11; the support member 11 includes a bottom plate 111, wherein the bottom plate 111 is provided with a groove 112, wherein the groove 112 is provided with a mounting position 113, wherein the mounting position 113 is used to mount a motor 2 connected with a fan blade 3; the support member 11 also includes a support plate 115, wherein a first end of the support plate 115 is connected to the bottom plate 111; and a second end of the support plate 115 is connected to the fixing member 12.

[0050] The installation position 113 is provided with a first screw hole 114 , and the first screw hole 114 is screw-connected to the base 21 of the motor 2 .

[0051] There are multiple first screw holes 114, and the number of the first screw holes 114 is not limited here. The base 21 of the motor 2 is provided with multiple second screw holes 211, and the number of the second screw holes 211 on the base 21 of the motor 2 is the same as the number of the first screw holes 114 on the mounting position 113, and each second screw hole 211 on the base 21 of the motor 2 is adapted to the corresponding first screw hole 114 on the mounting position 113.

[0052] Preferably, in the process of installing the motor 2 connected with the fan blade 3, the motor 2 is first aligned with the groove 112 on the bottom plate 111, so that the second screw hole 211 on the base 21 of the motor 2 and the first screw hole 114 of the installation position 113 are aligned, and then the motor 2 is placed from top to bottom into the groove 112 on the bottom plate 111. After the second screw hole 211 on the base 21 of the motor 2 and the first screw hole 114 of the installation position 113 are in contact with each other, a screw is inserted into the second screw hole 211 on the base 21 of the motor 2 and the first screw hole 114 of the installation position 113, so that the base 21 of the motor 2 is fixed in the groove 112 of the bottom plate 111.

[0053] The bottom plate 111 can be perpendicular to the support plate 115, or can form a certain angle with the support plate 115. In this embodiment, the bottom plate 111 is horizontally arranged, the support plate 115 is vertically arranged, the bottom plate 111 and the support plate 115 are perpendicular, and the bottom plate 111 and the support plate 115 form a T-shaped structure as an example.

[0054] The support plate 115 supports the bottom plate 111 and the motor 2, and can be screwed to the fixing member 12. In this embodiment, the fixing member 12 is a fan 121, and the second end of the support plate 115 is screwed to the bottom end of the fan 121 as an example.

[0055] The fan blades 3 connected to the motor 2 rotate in the wind tube 121. If the gap between the fan blades 3 and the wind tube 121 is too small, friction will occur between the fan blades 3 and the wind tube 121, causing the wind tube 121 with the above-mentioned fixing device 1 to fail to exhaust and dissipate heat normally and also emit loud noise.

[0056] Installing the base 21 of the motor 2 at the mounting position 113 in the groove 112 can fix the positions of the motor 2 and the fan blades 3, ensure a large gap between the fan blades 3 and the wind tube 121, and avoid friction between the fan blades 3 and the wind tube 121.

[0057] The mounting position 113 in the groove 112 of the fixing device 1 of this embodiment is provided with a first screw hole 114, and the first screw hole 114 is screwed to the base 21 of the motor 2. The first screw hole 114 of the mounting position 113 is adapted to the second screw hole 211 of the base 21 of the motor 2, and the screw is inserted into the second screw hole 211 of the motor 2 and the first screw hole 114 of the mounting position 113, so that the base 21 of the motor 2 is mounted in the groove 112 of the bottom plate 111. The support member 11 also includes a support plate 115, a first end of the support plate 115 is connected to the bottom plate 111, and a second end of the support plate 115 is connected to the fixing member 12. The support plate 115 supports the bottom plate 111 and the motor 2 on the bottom plate 111, so that when the base 21 of the motor 2 is mounted in the mounting position 113 in the groove 112 from top to bottom, the bottom plate 111 can bear the weight of the motor 2.

[0058] Example 3

[0059] like Figure 1-Figure 5 As shown, this embodiment provides a fixing device, including a support member 11 and a fixing member 12, wherein the fixing member 12 is connected to the support member 11; the support member 11 includes a bottom plate 111, wherein the bottom plate 111 is provided with a groove 112, wherein the groove 112 is provided with a mounting position 113, wherein the mounting position 113 is used to install a motor 2 connected with a fan blade 3; the support member also includes a support plate, wherein a first end of the support plate is connected to the bottom plate; and a second end of the support plate is connected to the fixing member.

[0060] like Figure 7-Figure 10 As shown, the existing fixing device for fixing the motor of the fan includes a bottom plate and a support plate. No groove is provided on the bottom plate, and the base of the motor is directly mounted on the bottom plate using screws.

[0061] When the motor of the existing fixing device is running at high speed for a long time, the motor will rub against the screw hole on the bottom plate, causing the screw hole to become larger. When the screw hole becomes larger, the fixing effect of the screw on the motor will become worse, and the motor will be displaced, which will reduce the gap between the fan blade connected to the motor and the wind tube, causing the fan blade to be stuck on the inner wall of the wind tube, and the wind tube cannot exhaust air outwards. It may also cause the fan blade to break. If the fan blade rotates after the fan blade breaks, it will cause a lot of noise.

[0062] For example, when the motor 2 rotates clockwise, the motor 2 applies a clockwise force to the fan blade 3. If the gap between the fan blade 3 and the inner wall of the wind tube 121 is small, the inner wall of the wind tube 121 will apply a counterclockwise force to the fan blade 3. The fan blade 3 remains stationary under the combined action of the two forces. As time goes by, the fan blade 3 may break.

[0063] The support plate 115 is perpendicular to the bottom plate 111 , and two ends of the bottom plate 111 are screw-connected to the inner wall of the air duct 121 .

[0064] The support plate 115 provides a vertical force to the bottom plate 111, and the inner wall of the wind tube 121 provides a horizontal force to the bottom plate 111. Under the joint action of the support plate 115 and the inner wall of the wind tube 121, the bottom plate 111 can be well fixed.

[0065] like Figure 6 As shown, the support member 11 further includes a connecting plate 116 , a first end of the connecting plate 116 is connected to the support plate 115 , and a second end of the connecting plate 116 is connected to the bottom plate 111 .

[0066] A connection plate 116 is provided between the bottom plate 111 and the support plate 115 to enhance the connection stability between the bottom plate 111 and the support plate 115 .

[0067] The depth of the groove 112 is 3 mm, and the groove 112 is adapted to the base 21 of the motor 2 .

[0068] A groove 112 with a depth of 3 mm is provided on the bottom plate 111 so that the bottom plate 111 is sunken by 3 mm, thereby reducing the vibration generated by the motor 2 during high-speed operation.

[0069] The bottom plate 111 with the groove 112 is a concave bottom plate. The use of the concave bottom plate prevents the fan blades 3 from rubbing against the inner wall of the wind tube 121 due to deviation in the installation position of the motor 2 when the user replaces the motor 2, thereby preventing the fan blades 3 from breaking, reducing the replacement frequency of the fan blades 3, and increasing the service life of the fan blades 3, the motor 2 and the wind tube 121.

[0070] The depth of the groove 112 of the fixing device 1 of this embodiment is 3 mm, and the groove 112 is adapted to the base 21 of the motor 2. The base 21 of the motor 2 is placed into the groove 112 from top to bottom, and then a screw is inserted into the mounting position 113 to fix the motor 2 in the groove 112. A groove 112 with a depth of 3 mm is opened in the middle of the bottom plate 111 to reduce the vibration generated by the motor 2 during high-speed operation and prevent the motor 2 from rubbing against the screw hole of the mounting position 113, thereby achieving that the motor 2 remains fixed when running at high speed for a long time. When the motor 2 is fixed, a certain distance is maintained between the fan blades 3 and the inner wall of the wind tube 121 to prevent the fan blades 3 from breaking, excessive noise, and the motor 2 from burning out due to continuous friction between the fan blades 3 and the inner wall of the wind tube 121.

[0071] Example 4

[0072] like Figure 1-Figure 5 As shown, this embodiment provides a fixing device, including a support member 11 and a fixing member 12, wherein the fixing member 12 is connected to the support member 11; the support member 11 includes a bottom plate 111, wherein the bottom plate 111 is provided with a groove 112, wherein the groove 112 is provided with a mounting position 113, wherein the mounting position 113 is used to install a motor 2 connected with a fan blade 3; the support member also includes a support plate, wherein a first end of the support plate is connected to the bottom plate; and a second end of the support plate is connected to the fixing member.

[0073] Both ends of the bottom plate 111 in the horizontal direction are connected to the fixing member 12 , and the length of the groove 112 is smaller than the length of the bottom plate 111 .

[0074] The two ends of the bottom plate 111 in the horizontal direction are screwed to the inner wall of the air cylinder 121, so as to better fix the relative position between the bottom plate 111 and the air cylinder 121. The groove 112 is located in the middle of the bottom plate 111, and the length direction of the groove 112 is consistent with the length direction of the bottom plate 111. The length of the groove 112 can be adjusted, that is, the air cylinder 121 is installed with a certain model of motor 2, and a groove 112 with the same length as the base 21 of the motor 2 is opened on the bottom plate 111, and the length of the groove 112 is not limited here.

[0075] The bottom plate 111 of the fixing device 1 of this embodiment is connected to the fixing member 12 at both ends in the horizontal direction, and the length of the groove 112 is less than the length of the bottom plate 111. The bottom plate 111 and the air cylinder 121 are connected by screws, so that the relative position between the bottom plate 111 and the air cylinder 121 can be better fixed. The size of the groove 112 is the same as the size of the base 21 of the motor 2, and the groove 112 of the corresponding length is opened on the bottom plate 111 according to the model of the motor 2 to be installed.

[0076] Example 5

[0077] like Figure 1 and Figure 5 As shown, this embodiment provides a fan, including the fixing device 1 of any one of embodiments 1-4, and the fan also includes the motor 2 and a plurality of the fan blades 3, and the plurality of the fan blades 3 are circumferentially arranged on the motor 2.

[0078] In this embodiment, a motor 2 is provided with three blades 3 in the circumferential direction, and the angle between each two adjacent blades 3 is 120 degrees as an example. The types of blades 3 include straight wing blades, curved wing blades, oblique wing blades and twisted wing blades. The cross section of the straight wing blade is straight, and the area gradually decreases from the root. The straight wing blade is suitable for low-speed fans, and has the advantages of simple structure and low cost. However, the energy utilization rate of the straight wing blade is not high, and the noise is also large, so it is not suitable for high-speed fans. The cross section of the curved wing blade is arc-shaped, and the area gradually decreases from the root. The curved wing blade has different curvature sizes and bending directions, and can form a variety of different curved wing blades. The main advantage of the curved wing blade is that it can reduce noise and improve energy utilization. The curved wing blade is suitable for low-speed and medium-speed fans, and can improve the performance of the fan to a certain extent. The cross section of the oblique wing blade is inclined. Compared with the straight wing blade and the curved wing blade, the oblique wing blade can provide greater wind force and has a higher energy utilization rate. However, due to the large deformation of the oblique wing blade, the life of the oblique wing blade is relatively short. The cross section of the twisted wing blade is curved. The twisted wing blade can improve the energy utilization rate of the fan and is suitable for high-speed fans. However, the cost of the twisted wing blade is relatively high. The type of the fan blade can be determined according to the type of the fan and the model of the wind tube. This embodiment does not limit the type of the fan blade.

[0079] The base of the motor is provided with second screw holes 211 on both sides, and the second screw holes 211 are adapted to the first screw holes 114 of the mounting position. The types of motors 2 are divided into DC motors, AC motors, stepper motors and servo motors. DC motors generally refer to rotating motors that can convert DC power into mechanical energy or mechanical energy into DC power. DC motors can realize the mutual conversion of DC power and mechanical energy.

[0080] AC motors are rotating motors that output or input alternating current. AC motors have a wide power range and simple structure. Stepper motors can convert electrical pulses into angular displacement. Generally, the angular displacement of stepper motors can be controlled by controlling the number of electrical pulses to achieve precise positioning. Servo motors can convert input voltage signals into mechanical output on the motor shaft, dragging the controlled components to achieve control purposes.

[0081] This embodiment provides a fan, comprising a fixing device 1 of any one of embodiments 1-4, and further comprising a motor 2 and a plurality of blades 3, wherein the plurality of blades 3 are circumferentially arranged on the motor 2. The motor 2 rotates clockwise, driving the blades 3 to rotate clockwise. The motor 2 rotates counterclockwise, driving the blades 3 to rotate counterclockwise. By adjusting the speed of the motor 2, the speed of the blades 3 can be adjusted, thereby adjusting the air outlet speed of the fan.

[0083] This embodiment provides a fan control method. Based on the fan in Embodiment 5, the method includes:

[0084] S1: Place the motor in the groove.

[0085] S2: Insert screws into the mounting position to connect the motor to the base plate.

[0086] S3: Start the motor to drive the fan blades to rotate.

[0090] This embodiment provides an electronic device, which includes a memory and a processor. The electronic device is applied to the robot in Example 6.

[0091] The processor may be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. A general-purpose processor may be a microprocessor or any conventional processor, etc.

[0092] Memory may include various types of storage units such as system memory, read-only memory (ROM), and permanent storage.

[0093] The memory stores executable codes, and when the executable codes are processed by the processor, the processor can execute part or all of the fan control method mentioned above.

[0094] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the application. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a restriction. Therefore, other examples of exemplary embodiments can have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in the subsequent accompanying drawings.

[0095] It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "above" other devices or structures would then be positioned "below" or "below" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used herein should be interpreted accordingly.

[0096] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0097] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
