Description

Technical Field

[0001] The present application relates to the technical field of clothes drying machines, and in particular to a motor with a self-locking function and a clothes drying machine. Background Art

[0002] The motor box of the existing electric clothes drying machine can control the extension or retraction of the wire rope, and correspondingly control the extension or retraction of the clothes drying rod. When the clothes drying rod is extended, clothes can be hung on it for drying, and when clothes are not needed for drying, they can be retracted, which can reduce space occupation and facilitate consumers' activities. Generally, the motor box of the electric clothes drying machine includes a motor, a worm, a turbine and a winding wheel. The worm is often configured as the rotating shaft of the motor, the turbine is meshed with the worm, the winding wheel is coaxially connected to the turbine or indirectly connected, and the outer surface of the winding wheel is connected to the outer surface of the winding wheel. A wire winding groove is arranged around the clothes drying rod, and the wire rope is wound in the wire winding groove. The motor can directly drive the worm to rotate, and correspondingly drive the turbine and the wire winding wheel to rotate, so as to extend or reel in the wire rope. In addition, the worm and the turbine will form a self-locking function, which can ensure that the wire winding wheel will not be pulled and rotated by the weight hung on the clothes drying rod (gravity), thereby ensuring that the extended length of the wire rope remains unchanged and is still the length required by the consumer. This can ensure that the clothes drying rod can be fixed at the height required by the consumer, so that the clothes hung on it can face the sun over a large area.

[0003] At present, the motor box of the clothes drying machine on the market only adopts the worm gear method to form self-locking, and there is no other self-locking method. If other structures cannot be created to replace the turbine worm gear structure to form motor self-locking, this will not be able to give full play to the initiative of relevant technical personnel, which is not conducive to the overall development of the clothes drying machine industry. Based on this, the present application proposes a motor that does not adopt the turbine worm gear self-locking structure. Utility Model Content

[0006] A further technical solution is that at least two driving grooves are arranged on the rotating member, and the stopping member has the same number of stopping parts as the driving grooves, and the stopping parts are connected to the inside of the driving grooves in a one-to-one correspondence.

[0007] A further technical solution is that the motor comprises a plurality of torsion springs, the torsion springs are arranged at intervals on the outer periphery of the rotating member, and a split coil is arranged between two adjacent torsion springs.

[0008] A further technical solution is that the stopper is connected to the end of the rotating member through a sleeve.

[0009] A further technical solution is that the motor further includes a planetary gear set;

[0010] The planetary gear set includes a sun gear, a plurality of planetary gears and a wheel carrier;

[0011] The sun gear is connected to the outer periphery of the rotating shaft;

[0012] The planetary gears are all arranged on one side of the wheel carrier and mesh with the sun gear externally;

[0013] The other side of the wheel frame is connected to the rotating member.

[0014] A further technical solution is that an inner gear ring is provided on the inner side of one end of the sleeve;

[0015] The wheel frame is provided with a connecting protrusion, and the rotating member is sleeved on the outer periphery of the connecting protrusion;

[0016] The sleeve is simultaneously sleeved on the outer circumference of the rotating member and part of the stopping member, and the inner gear ring is meshed with the planetary gear;

[0017] The end of the stopper extends from the other end of the sleeve and is configured to be connected to the winding wheel.

[0018] A further technical solution is that the main body further comprises a shell, a stator disposed inside the shell, and a rotor rotatably disposed inside the stator;

[0019] The rotor has the rotating shaft, and both ends of the rotating shaft are rotatably connected to the housing through bearings.

[0020] A further technical solution is that the end of the stopper is connected to the housing via a bearing.

[0021] A further technical solution is that the other end of the rotating shaft is provided with helical teeth, and the helical teeth are used to mesh with the turbine.

[0022] In a second aspect, the present application further proposes a clothes drying machine, which includes the motor with a self-locking function as described in the first aspect.

[0023] The present application proposes a motor with a self-locking function and a clothes drying machine. Compared with the prior art, the beneficial effects thereof are:

[0024] The rotation of the rotating shaft of the motor body can synchronously drive the rotating part, the torsion spring and the stopper to rotate. The torsion spring is driven to rotate by the rotating part. While rotating, it can shrink and its inner diameter can become smaller, thereby tightly squeezing the rotating part. The stopper is also driven to rotate by the rotating part, and it can synchronously drive a driving part such as a winding wheel to rotate, so as to extend or rewind the wire rope, and to stretch or store the clothesline.

[0025] Generally, when clothes are hung on the clothesline, the motor is in a stopped state - the shaft is in a free moving state, and the clothes hung on the clothesline exert a downward force on the clothesline, which drives the wire rope to extend. Under the compulsion of this force, the winding wheel tends to rotate, and accordingly, the stopper has a rotation tendency and wants to rotate relative to the rotating member. The stopping portion of the stopper will contact and squeeze the torsion spring at the moment of rotation, trying to stretch the end of the torsion spring and the rest of the torsion spring, which will make the inner diameter of the torsion spring tend to increase, and the inner diameter of the torsion spring will contact the inner wall of the sleeve at the moment of increasing, and give the inner wall of the sleeve a squeezing force Correspondingly, the inner wall of the sleeve will give a reaction force to the torsion spring to prevent the inner diameter of the torsion spring from increasing. Correspondingly, the torsion spring will also give a reaction force to the stop part of the stop member to prevent the stop member from rotating. At this time, it can be understood that the motor is self-locking. Preventing the stop member from rotating means preventing the driving member such as the winding wheel from rotating. Therefore, the length of the wire rope extended compared to the winding wheel remains unchanged, and the clothesline will not drop under the gravity of the clothes hung on it. Here, the motor of the present application has a self-locking function. Only when the shaft actively rotates can the rotating member, the stop member and the torsion spring be driven to rotate, which can drive the winding wheel to rotate, and the winding wheel cannot be driven to rotate by external force.

[0026] In addition, the present application also proposes a clothes drying machine using the above motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0038] like Figure 1-Figure 7 As shown in, an embodiment of the present application proposes a motor with a self-locking function in the first aspect, which includes: a main body with a rotating shaft 1, a torsion spring 2, a rotating member 3, a stopper 4 and a sleeve 5; the rotating member 3 is connected to one end of the rotating shaft 1 of the main body, and a driving groove 31 is provided on the rotating member 3; the end of the torsion spring 2 extends into the interior of the driving groove 31, and the rest of the torsion spring 2 is wound around the outer periphery of the rotating member 3; the stopper 4 has a connecting portion 41 and a stopping portion 42, the stopping portion 42 extends into the driving groove 31 and is close to the end of the torsion spring 2; the end of the connecting portion 41 away from the rotating member 3 is connected to a driving member; the sleeve 5 is sleeved on the outer side of the rotating member 3 and the torsion spring 2.

[0039] Based on the above technical solution, the rotation of the motor shaft 1 can synchronously drive the rotating member 3, the torsion spring 2 and the stop member 4 to rotate. The torsion spring 2 is driven to rotate by the rotating member 3. While rotating, it can shrink and its inner diameter can become smaller, thereby tightly squeezing the rotating member 3. The stop member 4 is also driven to rotate by the rotating member 3. It can synchronously drive the driving member such as the winding wheel 6 to rotate, so as to extend the wire rope (not shown in the accompanying drawings) or rewind the wire rope, so as to stretch the clothesline (not shown in the accompanying drawings) or retract the clothesline. Here, the motor of the present application can quickly drive the winding wheel 6 to rotate without deceleration, so as to quickly retract the clothesline.

[0040] Generally, when clothes are hung on the clothes drying pole, the motor is in a stopped state - the shaft 1 is in a free movable state, and the clothes hung on the clothes drying pole exert a downward force on the clothes drying pole, which drives the wire rope to extend. Under the compulsion of this force, the winding wheel 6 tends to rotate, and accordingly, the stopper 4 has a rotation tendency and wants to rotate relative to the rotating member 3. The stopper portion 42 of the stopper 4 will contact and squeeze the torsion spring 2 at the moment of rotation, and wants to stretch the end of the torsion spring 2 and the rest of the torsion spring 2, which will make the inner diameter of the torsion spring 2 tend to increase, and the inner diameter of the torsion spring 2 will contact the inner wall of the sleeve 5 at the moment of increasing, and give the inner wall of the sleeve 5 an extrusion force, correspondingly. On the ground, the inner wall of the sleeve 5 will give a reaction force to the torsion spring 2 to prevent the inner diameter of the torsion spring 2 from continuing to increase. Correspondingly, the torsion spring 2 will also give a reaction force to the stop portion 42 of the stop member 4 to prevent the stop member 4 from rotating. At this time, it can be understood that the motor of the present application is self-locking. Preventing the stop member 4 from rotating means preventing the winding wheel 6 from rotating. Therefore, the length of the wire rope extended compared to the winding wheel 6 remains unchanged, and the clothesline will not drop under the force of the gravity of the clothes hung on it. Here, the motor of the present application has a self-locking function. Only when the rotating shaft 1 actively rotates can the rotating member 3, the stop member 4 and the torsion spring 2 be driven to rotate, which can drive the winding wheel 6 to rotate, and the winding wheel 6 cannot be driven to rotate by external force.

[0041] It should be noted here that at the moment when the stop portion 42 of the stop member 4 is about to stretch open the end portion and the rest of the torsion spring 2, the stop portion 42 of the stop member 4 will generate an action force on the torsion spring 2, and correspondingly, the torsion spring 2 will also generate a reaction force on the stop portion 42 of the stop member 4, and, with the support of the inner wall of the sleeve 5, the reaction force of the torsion spring 2 on the stop portion 42 of the stop member 4 is infinite, so that the stop portion 42 of the stop member 4 cannot stretch it open, that is, the stop portion 42 of the stop member 4 cannot rotate, that is, the stop member 4 cannot rotate, and the motor forms a self-locking, at this time the winding wheel 6 cannot rotate, the wire rope cannot continue to extend, and the stretched height of the clothesline is fixed and cannot be changed by external force.

[0042] Based on this, the embodiment of the present application further proposes a clothes drying machine in the second aspect, which includes a clothes drying machine motor with a self-locking function as in the first aspect.

[0043] The clothes drying machine has a self-locking function, which can lock the clothes drying rod at a desired height, and the height of the clothes drying rod cannot be changed by external force.

[0044] See also Figure 3-Figure 7 As shown in FIG. 1 , in some embodiments, in order to facilitate the rotating member 3 to drive the stopping member 4 to rotate, a good self-locking can be formed between the stopping member 4 , the rotating member 3 and the torsion spring 2 .

[0045] At least two driving grooves 31 are provided on the rotating member 3 , and the stopping member 4 has the same number of stopping portions 42 as the driving grooves 31 , and the stopping portions 42 are connected to the inside of the driving grooves 31 in a one-to-one correspondence.

[0046] The end of the torsion spring 2 should penetrate into the interior of the driving groove 31 of the rotating member 3, and can be fixedly connected to the inner wall of the driving groove 31, or it may not be fixedly connected to the inner wall of the driving groove 31. Except for the two ends of the torsion spring 2, the rest of the torsion spring 2 can also extend into the driving groove 31, or the rest of the torsion spring 2 can be connected to some structures of the shape of its end, and this structure can extend into the driving groove 31. In this way, it can be ensured that the torsion spring 2 is connected to each driving groove 31; each stopper 42 will contact the end of the torsion spring 2, or the distance between the end of the torsion spring 2 is very small; in this way, the rotating shaft 1 rotates and drives the rotating member 3 to rotate, and the rotating member 3 will drive the torsion spring 2 to rotate, so that the inner diameter of the torsion spring 2 becomes smaller, which can tightly hold the rotating member 3, and the rotating member 3 can well drive the stopper 4 to rotate, so that it can drive the winding wheel 6 to rotate.

[0047] It should be explained here that the reason why the inner diameter of the torsion spring 2 becomes smaller while the torsion spring 2 rotates is that at the moment the rotating part 3 rotates, the torsion spring 2 is rapidly driven to rotate from a stationary state. Due to inertia, the length of the torsion spring 2 in the axial direction of the rotating part 3 is lengthened, and accordingly, the inner diameter of the torsion spring 2 will become smaller, which will cause the torsion spring 2 to tightly hold the rotating part 3. When the rotating part 3 stops rotating, the torsion spring 2 stops rotating, and it will slowly restore its original shape in the stationary state due to its own elastic force.

[0048] The axial direction of the rotating member 3 is the axial direction of the rotating shaft 1 .

[0049] It should also be noted here that the winding wheel 6 rotates to extend the wire rope or reel in the wire rope to extend or retract the clothesline. This action process is a common action process for retracting and extending the clothesline in the prior art and is well known to those skilled in the art, so it will not be described in detail here.

[0050] In order to make the self-locking force of the motor large enough, the following options are available: increasing the wire diameter of the torsion spring 2, using a material that is not easily deformed to make the torsion spring 2, increasing the friction coefficient of the inner wall of the sleeve 5, reducing the space between the inner wall of the sleeve 5 and the torsion spring 2, etc.

[0051] The number of torsion springs 2 may also be increased. For example, in some embodiments, the motor includes a plurality of torsion springs 2 . The torsion springs 2 are arranged at intervals on the outer periphery of the rotating member 3 , and a retaining ring 7 is provided between two adjacent torsion springs 2 .

[0052] Specifically, if the winding wheel 6 is subjected to external force, the stopper 4 tends to rotate, and the stop portion 42 of the stopper 4 will simultaneously open the multiple torsion springs 2. Relatively speaking, with the support of the inner wall of the sleeve 5, the multiple torsion springs 2 can simultaneously react to the stop portion 42 of the stopper 4 to prevent it from rotating. Under the action of the multiple torsion springs 2 and the inner wall of the sleeve 5, if the stopper 4 is to be rotated, the required external force is undoubtedly very large. Conversely, under the action of the multiple torsion springs 2 and the inner wall of the sleeve 5, the self-locking force of the motor is very large.

[0053] The dividing ring 7 can separate two adjacent torsion springs 2 to prevent them from influencing each other and affecting the self-locking effect. In addition, in some embodiments, the dividing ring 7 can fix the ends of the two adjacent torsion springs 2 facing each other on the rotating member 3, and the other ends of the two torsion springs 2 are free. In this way, at the moment when the rotating member 3 rotates, the torsion springs 2 will be driven to instantly reach a higher speed from a static state. At this time, the free end of each torsion spring 2 will be away from its fixed end, that is, each torsion spring 2 will be stretched in the axial direction of the rotating member 3, so that the torsion spring 2 will tightly hold the rotating member 3, and its inner diameter will become smaller and away from the inner wall of the sleeve 5. Therefore, it can be said that the torsion spring 2 can rotate under the drive of the rotating member 3 without abutting against the inner wall of the sleeve 5.

[0054] The rotating member 3 can drive the stopping member 4 to rotate through the driving groove 31, but since the rotating member 3 is connected to the connecting portion 41 of the stopping member 4, there will be friction between them, and this friction will affect the stability of the transmission between the rotating member 3 and the stopping member 4. Therefore, in order to ensure that the stability of the transmission between the rotating member 3 and the stopping member 4 is not affected by friction.

[0055] In some embodiments, the stopper 4 is connected to the end of the rotating member 3 via a sleeve 8 .

[0056] The shaft sleeve 8 can reduce the interference of the friction force between the rotating member 3 and the stop member 4, so that the rotating member 3 can smoothly drive the stop member 4 to rotate.

[0057] Generally, the rotation speed output by the rotating shaft 1 is relatively high, which directly drives the rotating member 3 and the stop member 4 to rotate. At this time, the rotation speed of the stop member 4 is also very high. The stop member 4 directly drives the winding wheel 6 to rotate. At this time, the rotation speed of the winding wheel 6 is also very high, and the speed of retracting and releasing the clothesline will be very fast, which may make consumers unable to avoid it and cause harm to them.

[0058] In this regard, a speed reduction mechanism is provided inside the motor with a self-locking function of the present application.

[0059] Specifically, the motor with self-locking function also includes a planetary gear set 9, which includes a sun gear 91, multiple planetary gears 92 and a wheel carrier 93. The sun gear 91 is connected to the outer periphery of the rotating shaft 1, and the planetary gears 92 are all arranged on one side of the wheel carrier 93 and mesh with the outside of the sun gear 91. The other side of the wheel carrier 93 is connected to the rotating part 3.

[0060] The rotation of the rotating shaft 1 can drive the sun gear 91 to rotate, and then drive the planetary gear 92 to rotate around the sun gear 91. Since the planetary gear 92 is arranged on the wheel frame 93, the rotation of the planetary gear 92 around the sun gear 91 will force the wheel frame 93 to rotate, and the other side of the wheel frame 93 is connected to the rotating member 3. The rotation of the wheel frame 93 will drive the rotating member 3 to rotate; the rotation of the sun gear 91 drives the planetary gear 92 to rotate, and then drives the wheel frame 93 to rotate. The transmission here achieves deceleration, and then the wheel frame 93 drives the rotating member 3 to rotate. At this time, the rotation speed of the rotating member 3 is already low, and the rotating member 3 drives the stopper 4 to rotate, so that it drives the winding wheel 6 to rotate. Correspondingly, the rotation speed of the winding wheel 6 is low, and the clothesline will be slowly raised or lowered. Consumers can avoid it calmly without being affected by the clothesline.

[0061] The motor with a self-locking function of the present application is installed inside the motor box of the clothes drying machine in order to reduce the internal space of the motor box occupied by it.

[0062] An inner gear ring 51 is provided on the inner side of one end of the sleeve 5, a connecting protrusion 931 is provided on the wheel frame 93, the rotating member 3 is sleeved on the outer periphery of the connecting protrusion 931, the sleeve 5 is sleeved on the outer periphery of the rotating member 3 and part of the stop member 4 at the same time, and the inner gear ring 51 is meshed with the planetary gear 92, and the end of the stop member 4 extends from the other end of the sleeve 5 and is configured to connect to the winding wheel 6.

[0063] The planetary gear set 9 has both deceleration and self-locking functions. When external force acts on one side of its wheel frame 93, its sun gear 91 will not rotate, that is, when external force acts on the wire rope on the winding wheel 6, the winding wheel 6 is subjected to force, which acts correspondingly on the stopper 4. The force on the stopper 4 acts on the rotating part 3, and the force on the rotating part 3 acts on the wheel frame 93. The wheel frame 93 will not be pulled either, thereby forming self-locking; the present application integrates the rotating part 3, the torsion spring 2 and the stopper 4 inside the sleeve 5, the sleeve 5 can be used as the ring gear of the planetary gear set 9, and the torsion spring 2, the stopper 4 and the sleeve 5 and the planetary gear set 9 can form a double self-locking, which can firmly lock the motor shaft 1 and the winding wheel 6 to prevent them from being pulled by external force.

[0064] Specifically, the motor with self-locking function of the present application also includes a housing 10, a stator 20 arranged inside the housing 10, and a rotor 30 rotatably arranged inside the stator 20; the rotor 30 has a rotating shaft 1, and both ends of the rotating shaft 1 are rotatably connected to the housing 10 through bearings 40.

[0065] When the motor with a self-locking function of the present application is energized, its rotor 30 will rotate relative to the stator 20, that is, the rotating shaft 1 will rotate, thereby driving the rotating member 3, the torsion spring 2 and the stopper 4 to rotate, and further driving the winding wheel 6 to rotate.

[0066] The manner in which the stopper 4 drives the winding wheel 6 to rotate may adopt a manner commonly used in the prior art, and a common connection structure may be provided between the stopper 4 and the winding wheel 6, which will not be described in detail herein.

[0067] Furthermore, in order to ensure that the stopper 4 can rotate smoothly, the end of the stopper 4 is also connected to the housing of the motor box through a bearing 40 .

[0068] In other embodiments, the other end of the rotating shaft 1 is provided with helical teeth, which mesh with the turbine. The turbine is part of the power system of the clothes drying machine.

[0069] A plurality of winding wheels 6 are arranged inside the motor box of the clothes drying machine, and the end of the stopper 4 can be connected to one or more of the winding wheels 6, and the remaining winding wheels 6 can be coaxially connected to the turbine or indirectly connected to the turbine; the rotating shaft 1 can be used as a worm, and the rotation of the worm (rotating shaft 1) can drive the turbine to rotate, and then drive the winding wheel 6 to rotate, so as to realize the retraction and extension of the wire rope and the retraction and extension of the clothes drying rod.

[0070] Alternatively, the other end of the rotating shaft 1 can also be connected to the rotating member 3, the torsion spring 2, the stopper 4 and the sleeve 5, and the stopper 4 can be connected to another winding wheel 6.
