Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
The invention provides an integrated resistance detection system of a clothes airing machine, which is applied to a power integration device 1 of the clothes airing machine. The power integration device 1 is also called a reduction gearbox and is used for driving the airing rod to ascend or descend; as shown in fig. 1, the power integration device 1 of the clothes airing machine comprises a shell, a winding device 2 and wire outlets, wherein two or more groups of winding devices 2 are arranged in the shell, the winding devices 2 are used for winding steel wire ropes 3, two or more steel wire ropes 3 in the power integration device 1 extend out of the winding devices 2 and are respectively led out from the wire outlets on two sides of the shell, and the power integration device is connected with an airing rod of the clothes airing machine by the steel wire ropes 3; the winding device 2 is driven by the driving mechanism to wind the steel wire rope 3 so as to realize the ascending or descending action of the airing rod. When the airing machine is in a normal working state, the steel wire rope 3 is in a tight state; when the airing rod of the airing machine encounters an obstacle in the descending process or the steel wire rope 3 is in a loose state after the steel wire rope 3 is broken, the obstacle detection system of the embodiment is used for detecting whether the airing rod encounters an obstacle or not and sending information in time when the rod encounters the obstacle, so that safety accidents are avoided.
The power integration device 1 is also integrated with a detection device and a supporting piece 4, so that the integration level of the internal structure of the clothes airing machine can be improved, the volume of the clothes airing machine is reduced, and meanwhile, the supporting piece 4 can expand the change range of the tightness state of the steel wire rope 3, so that the detection device can more accurately detect the steel wire rope 3 led out from the winding device 2, and the accuracy of detection in meeting resistance is improved.
In the resistance detection system, the abutting part 4 is linked with the steel wire rope 3 of the power integration device 1, so that the abutting part 4 can move along with the change of the tension and the relaxation state of the steel wire rope 3, and the moving mode can be a translation or swing mode and the like; the detection device is used for detecting the activity state of the holding piece 4 and providing corresponding detection information for the appointed terminal.
As shown in fig. 1, the supporting member 4 of the present embodiment includes a triggering portion, a pivoting portion and a touch portion, which are connected in sequence; the pivoting part is pivoted with the shell of the power integration device 1, and the touch part is tightly attached to the steel wire rope 3, so that the triggering part can swing along with the change of the tightening and loosening states of the steel wire rope 3. In this embodiment, in order to increase the contact area between the abutting member 4 and the steel wire rope 3, the roller 5 is further pivoted on the contact portion of the abutting member 4, and the roller 5 is in contact with the steel wire rope 3, so that the service life of the steel wire rope 3 can be prevented from being affected by severe friction between the abutting member 4 and the steel wire rope 3.
The abutting modes of the abutting piece 4 and the steel wire rope 3 comprise two modes, one mode is that a limiting space is formed by enclosing between the outer end part of the roll shaft 5 and a wire outlet on the shell, and the steel wire rope 3 in a tight state passes through the limiting space and directly abuts against the outer end face of the roll shaft 5; the steel wire rope 3 in the tight state directly presses the roll shaft 5 and applies downward force to the roll shaft 5, and when the steel wire rope 3 is changed into the loose state, the force which can be applied to the roll shaft 5 disappears, so that the trigger part of the abutting part 4 moves downwards.
The other is that a limiting space is formed by enclosing the roller shaft 5 and the end face of the abutting part 4, the steel wire rope 3 in the tight state penetrates through the limiting space and abuts against the inner end face of the roller shaft 5, at the moment, the steel wire rope 3 in the tight state provides upward pressure for the roller shaft 5, and when the steel wire rope 3 is changed into the loose state, the upward pressure disappears, so that the triggering part of the abutting part 4 moves upwards.
In this embodiment, the number of the supporting members 4 is the same as that of the steel wire ropes 3, and the two supporting members are two or more and are in one-to-one correspondence, and each supporting member 4 is linked with the corresponding steel wire rope 3. Each steel wire rope 3 is matched with the corresponding abutting piece 4, and when the tightness state of any one steel wire rope 3 changes, the abutting piece 4 corresponding to the steel wire rope 3 can move correspondingly along with the change of the tightness state of the steel wire rope 3.
In order to detect the active state of each supporting member 4, each supporting member 4 may be provided with its corresponding detecting device in a targeted manner, that is, the detecting devices are the same in number as the supporting members 4 and are in one-to-one correspondence with the supporting members 4, and each detecting device is respectively configured to detect the active state of its corresponding supporting member 4; when each detection device detects the movement of the corresponding holding piece 4, the detection device immediately sends detection information to the appointed terminal.
In addition, the number of the detection devices can be set to be one, one detection device is used for simultaneously detecting the activity state of each abutting piece 4, namely, the plurality of abutting pieces 4 share one detection device, and when any one of the abutting pieces 4 moves along with the change of the tightness state of the steel wire rope 3, the detection device immediately sends detection information to a specified terminal.
The detection device is used for detecting the activity state of the supporting piece 4, and when the supporting piece 4 moves along with the tightness state of the steel wire rope 3, the detection device can generate signal change and provide corresponding detection information for the appointed terminal when the signal changes. The detection device can be one of a detection switch 7, a laser ranging device and a pressure detection device; the detection switch 7 can be a microswitch, a key switch or the like which is triggered by pressing.
The detection switch 7 can be divided into two types, one type is that the detection switch 7 can be a normally closed switch, when the steel wire rope 3 is in a tight state and the abutting piece 4 abuts against the steel wire rope 3, the other end of the abutting piece 4 is far away from the detection switch 7, and at the moment, the detection switch 7 is switched off and does not output signals; when the steel wire rope 3 changes from a tight state to a loose state, the propping piece 4 gradually swings towards the direction of the detection switch 7 so as to trigger the detection switch 7, so that the detection switch 7 is turned on and outputs a signal. That is, when the state of the supporting member 4 away from the detection switch 7 is changed to the state that the supporting member 4 triggers the detection switch 7, the signal generated by the detection switch 7 is changed, and at this time, detection information is sent to a specified terminal to inform a user that the tightness state of the steel wire rope 3 is changed.
The other is that the detection switch 7 can be a normally open switch, that is, when the steel wire rope 3 is in a tight state and the abutting piece 4 abuts against the steel wire rope 3, the other end of the abutting piece 4 is kept in a state of abutting against the detection switch 7, so that the detection switch 7 is always kept in an open state and outputs a signal; when the steel wire rope 3 changes from the tight state to the loose state, the abutting piece 4 gradually moves away from the detection switch 7 to disconnect the detection switch 7 and no longer outputs signals, at the moment, the signals generated by the detection switch 7 change, and detection information can be sent to a designated terminal to inform a user that the steel wire rope 3 changes in the tight state.
The installation position of the detection switch 7 can be divided into two conditions, and the area between the side of the butting part 4 pivoted with the roller shaft 5 and the top of the shell defines the upper area of the butting part 4, so that the detection switch 7 can be installed in the upper area of the butting part 4; alternatively, the detection switch 7 may be disposed in a lower region of the holding member 4. The specific installation position of the detection switch 7 can be determined according to the abutting mode between the steel wire rope 3 and the abutting piece 4 and the normally open/normally closed state of the detection switch 7. For example: when the inner end face of the roller shaft 5 abuts against the steel wire rope 3 in a tight state, the detection switch 7 can be arranged in the area above the abutting piece 4, the state that the detection switch 7 is far away from the trigger part of the abutting piece 4 is kept, when the steel wire rope 3 is in a loose state, the trigger part of the abutting piece 4 moves upwards to gradually approach and trigger the detection switch 7, and the function of detecting resistance can be achieved.
The detection switch 7 executes the first or second detection mode, as long as the designated terminal receives the detection information sent by the detection switch 7 due to the signal change, which represents that the tightness state of the steel wire rope 3 changes, and at the moment, corresponding prompt or operation is immediately made to inform the user of the abnormal condition.
Similarly, the pressure detection device may be a pressure sensor, and the pressure detection device also detects the active state of the holding member 4 by using the way that the holding member 4 actually contacts to generate a pressure signal and the holding member 4 moves away from the pressure signal to disappear. The laser distance measuring device can be a laser distance measuring sensor, the laser detection sensor is used for detecting the distance between the sensor and the abutting piece 4, when the laser detection sensor detects that the distance changes, the distance signal output by the laser detection sensor also changes, and the laser distance measuring device is further used for detecting the moving state of the abutting piece 4. When the signals of the pressure detection device and the laser ranging device change, which means that the activity state of the abutting piece 4 changes, corresponding detection information is sent to the appointed terminal, and the appointed terminal can prompt a user that the tightness state of the steel wire rope 3 changes.
In this embodiment, the abutting member 4 is further provided with a resetting device, and the resetting device is used for driving the abutting member to move so as to keep the abutting member in abutting contact with the steel wire rope 3. The reset device may be an elastic member, such as a torsion spring 6, which has elasticity, in this embodiment, the torsion spring 6 is disposed near the reference point of the abutting member 4 to provide elasticity for the abutting member 4, that is, when the steel wire rope 3 is in a tight state, the torsion spring 6 generates a certain elastic deformation under the action of the abutting member 4; when the steel wire rope 3 is changed from the tight state to the loose state, the abutting part 4 is in the state without external force, and at the moment, the torsional spring 6 restores the elastic deformation process to drive the abutting part 4 to rotate clockwise rapidly, so that the swinging amplitude of the abutting part 4 is larger, and the detection accuracy of the detection device is improved.
As shown in fig. 1 to 3, the resistance encountering device of the present embodiment is provided with two abutting pieces 4, the two abutting pieces 4 correspond to the two steel wire ropes 3 one by one, the two abutting pieces 4 are respectively arranged at the left and right sides of the vertical center line of the power integration device 1, and the two abutting pieces 4 share one detection switch 7; each steel wire rope 3 abuts against the corresponding abutting part 4 when in a tight state, an included angle exists between each abutting part 4 and a horizontal line, specifically, the two abutting parts 4 are inclined towards the position of the common detection switch 7, and compared with the horizontal abutting part 4, the inclined abutting parts 4 can fully utilize the limited space in the power integration device 1, and simultaneously can shorten the moving distance required by the abutting parts 4 for triggering the detection switch 7, so that the detection switch 7 is touched to trigger the detection switch 7 more quickly; the detection switch 7 immediately sends detection information to the clothes airing machine terminal after entering a trigger state, and the clothes airing machine terminal immediately performs emergency stop or clothes airing rod lifting operation according to the detection information; and detection information can be sent to terminals such as a mobile phone, a tablet, a buzzer and the like, so that a corresponding alarm prompt is made to inform a user of abnormal conditions.
As shown in fig. 4 and 5, if the abutting member 4 is linked by directly abutting against the outer end surface of the roller shaft 5, one swinging member 8 can be used to link the tightness of the two steel wire ropes 3 at the same time; the method specifically comprises the following steps: the middle part of the swinging piece 8 is connected to the shell of the power integration device 1 as a reference point, and two ends of the swinging piece 8 are respectively abutted against the two steel wire ropes 3 in the tight state, so that a stable interaction force exists between one swinging piece 8 and the two steel wire ropes 3 in the tight state. When any one of the steel wire ropes 3 is changed from a tight state to a loose state, the force of the steel wire rope 3 pressing the swinging piece 8 disappears, so that the stable interaction force between the swinging piece 8 and the steel wire rope 3 is broken, and one end of the swinging piece 8 corresponding to the steel wire rope 3 with the changed loose state is tilted up under the action of inertia, so that the whole swinging piece 8 is driven to rotate by taking the reference point as an axis; and the rotation state of the swinging piece 8 is detected by using a detection device, and the function of detecting resistance can be realized.
The type of the detection device and the detection method in this embodiment are the same as those in the embodiment in which the linkage is realized by using two or more holding pieces 4, and a detailed description thereof will not be given here.
The invention also provides a clothes airing machine which comprises the resistance detection system, after the resistance detection system sends detection information to the clothes airing machine, a motor used for driving the winding device 2 in the clothes airing machine immediately executes emergency stop operation or reverse driving operation after receiving the detection information, so that the clothes airing rod is controlled to be emergency stopped or lifted, and safety accidents are avoided.
The clothes airing machine equipment provided by the invention and the embodiment are based on two aspects of the same inventive concept, and the implementation process has been described in detail in the foregoing, so that those skilled in the art can clearly understand the structure and implementation process of the clothes airing machine in the embodiment according to the foregoing description, and for the sake of brevity of the description, the details are not repeated herein.
