DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

[0044] As shown in Figure 1 , the present application provides a support device, which comprises a rack 1 and a buffer support 2, and the buffer support 2 is provided with a first action unit; a moving device is installed on the rack 1 through the buffer support 2, and the vibration generated by the operation of the moving device can be at least converted into kinetic energy of the first action unit to be attenuated by buffering.

[0045] Specifically, in the present embodiment, the moving device is taken as a fan for specific description.

[0046] That is, the fan is installed on the rack 1 through the buffer support 2, and when the fan operates, the vibration caused by the rotation of the blade and the rotation of the motor can be attenuated by energy absorption and buffering of the first action unit.

[0047] The support device provided by the application sets a buffer support 2 on the rack 1 of the module machine, the buffer support 2 has a first action unit therein, and can play a certain buffering and damping effect on the vibration of the motor during operation, so that the noise caused by the vibration of the motor 3 and the machine set can be greatly reduced.

[0048] Specifically, the buffer support 2 includes an upper support 21 and a lower support 22, the lower support 22 is connected with the rack 1, and the upper support 21 is connected with the fan; the first action unit includes an elastic member arranged between the upper support 21 and the lower support 22.

[0049] In the embodiment, the vibration buffering of the first action unit is achieved by the elastic expansion and contraction of the elastic member, that is, the vibration force of the fan during operation is buffered and eliminated in the process of reciprocating expansion and contraction, thereby playing a damping effect.

[0050] Further, the elastic member is a buffer spring 23.

[0051] As shown in Figure 1 The upper support 21 and the lower support 22 are both circular ring structures, and the buffer springs 23 are arranged along the circumferential direction of the upper support 21 at intervals, so as to maintain the balance and stability between the upper and lower supports.

[0052] As an optional embodiment of the application, the buffer support 2 further has a second action unit arranged therein, which can adjust the height thereof, so as to adjust the height between the fan and the rack 1.

[0053] Further, the height between the blades of the fan and the rack 1 is adjusted, so as to avoid interference between the blades 4 and the rack 1.

[0054] Further, a second action unit which can adjust the relative height between the motor and the rack is arranged in the buffer support, when the height between the blades and the cross beam of the rack is insufficient and collision occurs, the distance sensor on the cross beam will provide a signal to the second action unit on the buffer support, and the hydraulic mechanism will be controlled to lift the height, so as to avoid collision between the blades and the cross beam of the machine set; when the distance is too high, the hydraulic mechanism will also lower the height, so as to ensure that the blades are kept at a suitable height.

[0055] Specifically, in the embodiment, the second action unit includes a hydraulic mechanism 24 and a fixed buckle 25 arranged between the lower support 22 and the upper support 21.

[0056] The extension and contraction of the hydraulic mechanism 24 can drive the lifting of the upper support 21, and in the lifting process of the upper support 21, the buffer spring 23 will be stretched or compressed, and through the above structure adjustment, the height adjustment of the buffer support 2 can be achieved, so as to adjust the height between the blades 4 of the fan and the rack 1, and ensure that the blades 4 are always within a suitable height range, and avoid too low or too high height.

[0057] As shown in Figure 3 and Figure 4 , the fixed buckle 25 includes a guide rail shell 251, a pressing rod 252, a locking piece 253 and a pushing spring 254, the pressing rod 252 is in the shape of 7, one end is slidably arranged in the guide rail shell 251 through the locking piece 253, the locking piece 253 is connected with the guide rail shell 251 through the pushing spring 254, the other end of the pressing rod 252 is arranged in parallel on the top of the guide rail shell 251 to form a clamping piece part between the pressing rod 252 and the guide rail shell 251, the clamping piece part is used for clamping the side of the upper support 21 and limiting the position of the upper support 21, and the top of the pressing rod 252 is fixedly connected with the upper support 21 and can move together; the state of the locking piece 253 is switched once for each pressing of the pressing rod 252.

[0058] In operation, no matter whether the height of the buffer support 2 is increased or decreased, the hydraulic mechanism 24 needs to be slightly contracted downward to give a pressing force to the fixed buckle 25, so as to switch the state of the fixed buckle 25 from the locked state to the released state, and then the hydraulic mechanism 24 is regularly contracted and expanded to drive the upper support 21 to ascend and descend, after adjustment, the hydraulic mechanism 24 is slightly contracted downward to give a pressing force to the fixed buckle 25, so as to switch the state of the fixed buckle 25 from the released state to the locked state, so as to lock the positions of the upper support 21 and the lower support 22.

[0059] It should be noted that the structure of the fixed buckle 25 is prior art, and an automatic telescopic locking structure similar to an automatic ballpoint pen is adopted, when the hydraulic mechanism is contracted or stretched, a force is given to the buckle mechanism, so that automatic telescopic locking is realized, and a fixing effect is achieved.

[0060] Further, the support device further comprises a control unit arranged on the rack 1, and the control unit is electrically connected with the second action unit. According to the distance signal obtained by the control unit, the distance signal is compared with the preset safety distance, if the obtained distance signal falls within the safety distance range, the second action unit does not need to act, if the obtained distance signal is greater than or less than the safety distance, the second action unit needs to act to adjust the height of the buffer support 2, so as to adjust the height between the blade 4 and the rack 1, so that the blade neither interferes with the rack 1 due to being too low, nor rubs with the top component due to being too high.

[0061] Further, the control unit comprises an infrared distance sensor 26.

[0062] As shown in Figure 2 , the present application provides a fan, which comprises a motor 3, a blade 4 and a support device, the blade 4 is installed on the motor 3, and the motor 3 is installed on the support device.

[0063] The vibration and noise reducing type automatic height adjusting motor support device reduces the overall vibration and noise of the fan, increases the overall production efficiency of the fan, reduces the production and assembly quality risk of the fan, and improves the operation reliability of the motor.

[0064] Specifically, the control unit in the support device is installed on the rack 1 corresponding to the tip position of the blade 4.

[0065] The module machine provided by the application comprises the fan.

[0066] The module machine provided by the application comprises the fan.

[0067] The module machine provided by the application comprises the fan.

[0068] As shown in the figure, the application further provides a control method based on the control method of the fan, comprising the following steps: Figure 5

[0069] Step S1, the fan is running, and the vibration generated by the rotation of the blade 4 and the motor 3 is transmitted to the buffer support 2 in the support device.

[0070] Step S2, when the buffer support 2 is subjected to the vibration transmitted by the fan, the vibration is transmitted to the first motion unit.

[0071] Step S3, when the first motion unit receives the vibration generated by the operation of the fan, the vibration is at least converted into the kinetic energy of the first motion unit to buffer and attenuate the vibration.

[0072] Specifically, the following steps are further included,

[0073] Step S4, before the operation of the fan, the control unit in the support device instantaneously acquires the distance information between the rack 1 and the tip of the blade 4 during the power-on process, and transmits the distance information to the second action unit.

[0074] Step S5, the second action unit compares the acquired distance information with the preset safe distance.

[0075] ​Step S6, when the comparison result in step S5 is less than the safety distance, that is, the height of the blade 4 tip is lower than the appropriate safety range, the second action unit starts to act, first, the fixed buckle 25 reacts instantaneously, the hydraulic mechanism 24 instantaneously stretches, drives the buffer spring 23 to stretch, makes the upper support 21 drive the motor 3 and the blade 4 height to rise, increases the height of the buffer support 2;

[0076] Step S7, when the comparison result in step S5 is greater than the safety distance, that is, the height of the blade 4 tip is greater than the appropriate safety range, the second action unit starts to act, first, the fixed buckle 25 reacts instantaneously, the hydraulic mechanism 24 instantaneously contracts, drives the buffer spring 23 to contract, makes the upper support 21 drive the motor 3 and the blade 4 height to lower, reduces the height of the buffer support 2;

[0077] Step S8, after the height of the buffer support is adjusted in step S6 and step S7, when the safety distance reaches the appropriate height, the second action unit stops acting;

[0078] Specifically, for example, in step S6, when the blade 4 rises to the appropriate height, the second action unit stops moving, the fixed buckle 25 acts to fix and keep the buffer support 2 stable;

[0079] Specifically, for example, in step S7, when the blade 4 lowers to the appropriate height, the second action unit stops moving, the fixed buckle 25 acts to fix and keep the buffer support 2 stable;

[0080] In step S6 and step S7, if the height of the blade 4 rising or lowering does not meet the appropriate height, that is, the safety distance is not reached, then the distance parameter acquisition is continued through the infrared distance sensor, and then the comparison is continued, the hydraulic mechanism continues to rise and fall, so as to realize the height adjustment until the safety distance is met.

[0081] In fact, it is through the distance sensor to sense the height difference between the blade 4 tip and the rack to adjust the height difference between the upper support 21 and the lower support 22 to reach the appropriate tail vertebra, to ensure that the blade 4 runs without obstacles and is not affected; at the same time, in the process of fan operation, the upper support 21, the lower support 22 and the buffer spring 23 constitute the buffer support 2, so that the vibration noise generated by the fan is further attenuated through the buffer support 2, thereby reducing the noise of the unit.

[0082] Specifically, in step S6 and step S7, the second action unit starting to act includes

[0083] The fixed buckle 25 is opened to loosen the locking position between the upper support 21 and the lower support 22;

[0084] The hydraulic mechanism 24 acts to drive the upper support 21 to rise and fall, thereby increasing or reducing the height;

[0085] Specifically, in step S8, the second action unit stops action includes

[0086] The fixed buckle 25 is locked to lock the locking position between the upper support 21 and the lower support 22.

[0087] When the fan is running, the vibration and noise generated by the motor 3, the blade 4 and the related structure of the support gradually attenuate through the damping device composed of the damping spring and other power units in the upper and lower supports of the device, thereby reducing the overall noise of the fan, achieving the effect of vibration and noise reduction.
