Description

Technical Field

[0001] The utility model belongs to the technical field of motor modules of clothes drying racks, and in particular relates to an emergency stop structure and a motor module. Background Art

[0002] The electric clothes drying rack controls the reeling and releasing of the rope by driving the reeling wheel driven by a driving motor, wherein during normal reeling, the rope is tightened by the pulling force of the clothes drying rod, when the clothes drying rod is pushed by external force and the rope cannot be tightened, the reeling wheel easily causes the rope to be entangled during reeling, and the existing solution is to set an emergency stop mechanism in the driving housing and pass the rope through the emergency stop mechanism, when the rope is slack, the emergency stop mechanism controls the driving motor to stop working; however, an emergency stop distance of the emergency stop mechanism that is too small will cause the emergency stop control to be too sensitive, thereby affecting the efficiency of rope reeling, while an emergency stop distance of the emergency stop mechanism that is too large will cause the emergency stop control to be too slow, thereby causing the rope to be entangled.

[0003] Therefore, how to ensure the cable winding efficiency while avoiding the cable entanglement is a technical problem that needs to be solved urgently in this field. Utility Model Content

[0004] The purpose of the utility model is to provide an emergency stop structure and a motor module.

[0005] In order to solve the above technical problems, the utility model provides an emergency stop structure for a clothes drying machine module, including: a control switch, which is electrically connected to a controller; and a movable bracket, which is located on one side of a winding wheel and has a trigger portion at its far end, and a rope threading opening is also opened at the far end; when the rope is taut, the straight-line distance between the trigger portion and the switch contact of the control switch is 20-40mm; and when the rope is loose, the movable bracket drives the trigger portion to resist the switch contact, so that the controller controls the winding wheel to stop winding the rope.

[0006] Preferably, the proximal end of the movable bracket is elastically hinged on the inner wall of the driving housing.

[0007] Preferably, a hinge shaft is provided at the proximal end of the movable bracket; an elastic member is provided on the hinge shaft sleeve; and when the elastic member relaxes the cable, the trigger portion is driven to rebound and abut against the switch contact.

[0008] Preferably, the elastic member is a return torsion spring; one end of the return torsion spring abuts against the inner wall of the driving housing, and the other end of the return torsion spring extends and abuts against the proximal end of the movable bracket, so that the return torsion spring drives the trigger part to rebound and abut against the switch contact when the cable is relaxed.

[0009] Preferably, the movable bracket also includes a supporting portion, wherein the trigger portion extends from the end of the supporting portion and forms an obtuse angle; when the trigger portion abuts against the switch contact, they are in approximately vertical contact, so that the end face of the trigger portion is approximately parallel to the contact surface of the switch contact.

[0010] Preferably, when the cable is tightened, the rolling rod in the through-hole contacts the cable.

[0011] Preferably, the penetration opening is rectangular, with a width of 3-7 mm and a length of 25-40 mm.

[0012] Preferably, the driving housing has wire outlets on both sides; the driving motor is controlled by a controller and installed in the driving housing, and output shafts are respectively provided at both ends of the driving housing; a mirror-arranged winding wheel is connected to the output shaft of the driving motor through a transmission structure; a pair of the above-mentioned emergency stop structures are respectively arranged between the winding wheel and the wire outlet.

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] like Figures 1 to 4 As shown, at least one embodiment provides an emergency stop structure for a clothes drying machine module, comprising: a control switch 1, which is electrically connected to a controller 2; and a movable bracket 3, which is located on one side of a winding wheel 6, and a trigger portion 31 is provided at its far end, and a threading opening 311 for a rope 4 is also provided at the far end; when the rope 4 is tightened, the straight-line distance between the trigger portion 31 and the switch contact 11 of the control switch 1 is 20-40 mm; and when the rope 4 is loose, the movable bracket 3 drives the trigger portion 31 to abut against the switch contact 11, so that the controller 2 controls the winding wheel 6 to stop the rope The cable 4 is wound up; in short, the cable 4 passes through the insertion opening 311 and is tightened by the clothes-drying rod so that the switch contact 11 is not triggered, and the normal winding of the cable 4 can be achieved. When the winding wheel 6 is in the process of winding, the clothes-drying rod is pushed, the movable bracket 3 moves upward, and the switch contact 11 is triggered by the top of the trigger bracket, and the signal is transmitted to the controller 2, and the controller 2 controls the driving motor to stop working to avoid the entanglement of the cable 4, and the vertical movement distance of the top of the trigger bracket is 20-40mm, which can ensure the winding efficiency while avoiding the entanglement of the cable 4.

[0038] In some embodiments, the proximal end of the movable bracket 3 is elastically hinged on the inner wall of the driving housing 5; in short, by elastically hingedly hinged the proximal end of the movable bracket 3 on the inner wall of the driving housing 5, the movable bracket 3 can always tend to approach the control switch 1, and when the cable 4 is loose, the control switch 1 is ensured to be stably triggered.

[0039] In some embodiments, a hinge shaft is provided at the proximal end of the movable bracket 3; the hinge shaft sleeve is provided with an elastic member 32; when the elastic member 32 causes the cable 4 to relax, it drives the trigger part 31 to rebound and abut against the switch contact 11; in short, by sleeved on the hinge shaft, when the cable 4 relaxes, the elastic member 32 will bounce the movable bracket 3 so that the trigger part 31 abuts against the switch contact 11.

[0040] In some embodiments, the elastic member 32 is a reset torsion spring 321; one end of the reset torsion spring 321 abuts against the inner wall of the driving housing 5, and the other end of the reset torsion spring 321 extends and abuts against the proximal end of the movable bracket 3, so that when the cable 4 is relaxed, the reset torsion spring 321 drives the trigger part 31 to rebound and abut against the switch contact 11; in short, when the cable 4 is tightened, the movable bracket 3 is pressed down to store energy in the reset torsion spring 321, and when the cable 4 is relaxed, the reset torsion spring 321 drives the movable bracket 3 to rotate upward.

[0041] In some embodiments, the movable bracket 3 also includes a supporting portion 33, wherein the triggering portion 31 extends from the end of the supporting portion 33 and forms an obtuse angle; when the triggering portion 31 abuts against the switch contact 11, they are in approximately vertical contact, so that the end face of the triggering portion 31 is approximately parallel to the contact face of the switch contact 11; in short, when the triggering portion 31 abuts against the switch contact 11, it is approximately vertical, so that the end face of the triggering portion 31 rather than the edge of the triggering portion 31 can contact the switch contact 11, thereby ensuring that the switch contact 11 can be well triggered; further, the supporting portion 33 includes a pair of supporting rods 331, and the triggering portion 31 is formed by the obtuse extension of the supporting rods 331, and the two ends of the supporting rods 331 are connected by a cross beam 332 to form a closed area, and the structure is simple and reliable.

[0042] In some embodiments, when the cable 4 is tightened, the rolling rod 34 in the insertion opening 311 contacts the cable 4; in short, the rolling rod 34 can prevent the cable 4 from rubbing against the insertion opening 311, which may cause the cable 4 to break; further, a mounting plate 35 is provided at the corner of the support rod 331, and a mounting pin 36 is inserted on the mounting plate 35, and the rolling rod 34 is rotatably provided on the mounting pin 36.

[0043] In some embodiments, the insertion opening 311 is rectangular, with a width of 3-7 mm and a length of 25-40 mm; in short, the width of the insertion opening 311 is determined by the diameter of the cable 4, but if the width of the insertion opening 311 is too large, it will easily cause the cable 4 to shake up and down, and the length of the insertion opening 311 needs to be adapted to the width of the winding wheel 6 to avoid friction between the cable 4 and the side wall of the insertion opening 311, thereby increasing the service life of the cable 4.

[0044] In some embodiments, a driving housing 5 has a wire outlet 51 on both sides thereof; a driving motor is controlled by a controller 2 and installed in the driving housing 5, and output shafts are respectively provided at both ends thereof; a mirror-set winding wheel 6 is connected to the output shaft of the driving motor through a transmission structure; a pair of the above-mentioned emergency stop structures are respectively arranged between the winding wheel 6 and the wire outlet 51.

[0045] In some embodiments, the vertical distance between the switch contact 11 and the axis of the winding wheel 6 is 47.5-48.5 mm; in short, the switch contact 11 is slightly higher than the axis of the winding wheel 6 so that the retraction and release of the cable 4 will not interfere with the control switch 1.

[0046] In some embodiments, the wire outlet path of the winding wheel 6 is led out from the installation position of the movable bracket 3 to the wire outlet 51; in short, the appearance path of the winding wheel 6 is tangent to the winding wheel 6, and the installation position of the movable bracket 3 is lower than the winding wheel 6, ensuring the smooth appearance of the rope 4.
