DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0049] In the prior art, most electronic door locks use a DC motor as the drive servo element of the clutch drive mechanism. However, when the DC motor is working, problems such as mechanical wear, arc ablation, and oxidation of the commutator occur, resulting in phenomena such as commutation "dead points", contact resistance, and wear failure when the traditional DC motor is used for the servo drive of the clutch and lock tongue mechanism of the electronic door lock. Therefore, the DC motor electronic lock in the prior art is difficult to meet the product requirements of high life and high stability.

[0050] Based on the above problems of the prior art, the present invention provides a motor clutch mechanism and an intelligent door lock. As shown in the figure, the motor clutch mechanism includes: a housing 100; a drive assembly 200, the drive assembly 200 is arranged inside the housing 100, the drive assembly 200 includes a pushing member 210, and the pushing member 210 is movably arranged; a clutch assembly 300, the clutch assembly 300 is arranged inside the housing 100, the clutch assembly 300 includes a clutch pin 311, and the clutch pin 311 is movably arranged; the drive assembly 200 and the clutch assembly 300 are arranged side by side, and the pushing member 210 abuts against one end in the moving direction of the clutch pin 311.

[0051] The present invention arranges a drive assembly 200 inside the housing 100 of the motor clutch mechanism, and at the same time arranges a clutch assembly 300 side by side. The pushing member 210 arranged on the drive assembly 200 abuts against the clutch pin 311 arranged on the clutch assembly 300. When the drive assembly 200 is started, the pushing member 210 pushes the clutch pin 311 to achieve the effect of opening or locking. The structure of the present invention is stable and has an extremely long service life, and can meet the requirements of high stability in electronic door locks.

[0052] In the above embodiment, as Figure 1As shown, the housing 100 includes two parts, namely the housings 100 disposed opposite to each other on the left and right sides in the figure. The two housings 100 have complementary structures. When the two housings 100 are relatively installed and combined, a box body with a cavity inside is formed. In the actual setting process, the housing 100 disposed on the left side in the figure is disposed outside the door panel, and the housing 100 disposed on the right side in the figure is disposed inside the door panel. The two clamp the driving assembly 200 and the clutch assembly 300. At the same time, a plurality of mounting positions are provided on the housing 100, and the mounting positions cooperate with the mounting structures provided on the driving assembly 200 and the clutch assembly 300, so as to install the driving assembly 200 and the clutch assembly 300 inside the housing 100 at a predetermined distance. In a state where the relative positions of the driving assembly 200 and the clutch assembly 300 are fixed, a pushing member 210 provided in the driving assembly 200 abuts against a clutch pin 311 provided in the clutch assembly. (Both the above-mentioned pushing member 210 and the clutch pin 311 are movably arranged, and their specific connection relationship will be explained in detail below). In the actual use process, the user operates through the handle to drive the driving assembly 200 to rotate. At this time, the pushing member 210 moves, and pushes the clutch pin 311 to move within a predetermined range of distance, thereby achieving the effect of opening or locking.

[0053] Specifically, in this embodiment, as Figure 2 shown, the driving assembly 200 further includes: a driving machine housing 220, a motor group 230, a first driving wheel 240, a second driving wheel 250, a compression push plate 260, and a return spring 270. Among them, the driving machine housing 220 is also composed of two relatively arranged housings. The relative structures of the two driving machine housings 220 are mutually adapted. When the two driving machine housings 220 are combined with each other, a box body with a cavity inside is formed, and the above-mentioned multiple components are all installed inside the cavity formed by the driving machine housing 220.

[0054] Among them, the motor group 230 is used to provide power. The structural style of the motor group 230 is specifically as Figure 3As shown, it includes a motor 231, a drive shaft 232 provided on the motor 231, a motor gear 233, a printed circuit board 234, and a sensor 235 provided on the printed circuit board 234. Specifically, the motor 231 adopts a stepper motor in this embodiment. A stepper motor is an open-loop control element that converts an electrical pulse signal into an angular displacement or a linear displacement. Under non-overloaded conditions, the rotation speed and stop position of the motor only depend on the frequency and number of pulse signals, and are not affected by load changes. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction, which is called the "step angle". Its rotation runs step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses to achieve the purpose of accurate positioning; at the same time, the rotation speed and acceleration of the motor can be controlled by controlling the pulse frequency to achieve the purpose of speed regulation. The drive shaft 232 is provided on the motor 231 and is connected to the rotor inside the motor 231. When the motor 231 receives a drive signal command, it drives and rotates, driving the drive shaft 232 to rotate; the motor gear 233 is provided on the drive shaft 232, and the drive shaft 232 and the motor gear 233 are fixedly connected through irregular holes. When the drive shaft 232 rotates, the motor gear 233 rotates synchronously.

[0055] During the actual setting process, the motor 231 is driven to rotate by a square wave alternating drive method. The printed circuit board 234 is welded to the terminal of the motor 231, and the sensor 235 is welded to the printed circuit board 234. The printed circuit board 231 has positions for external signal interfaces of the motor 231 and the sensor 235.

[0056] A printed circuit board 234 is fixed on one side of the motor 231. The printed circuit board 234 is connected to a preset power supply, and there is an electrical connection between the printed circuit board 234 and the motor 231. The printed circuit board 234 provides power for the motor 231 and transmits control signals at the same time, thereby controlling the motor 231 to rotate in a preset state; a sensor 235 is also provided on the printed circuit board 234. This sensor 235 is a magnetic sensor. The sensor 235 is electrically connected to the printed circuit board 234. The sensor 235 generates an induction signal by sensing the change in the magnetic field intensity nearby and feeds it back into the printed circuit board 234 to realize the feedback of the state of the motor clutch mechanism, thereby controlling the further movement of the motor 231.

[0057] The sensor 235 is specifically arranged on one side corresponding to the position of the above-mentioned pusher 210. A magnetic member is arranged at the position of the pushing part on the pusher 210. The magnetic member is a component made of permanent magnet material, such as alloy permanent magnet material, including rare earth permanent magnet material (neodymium iron boron Nd2Fe14B), samarium cobalt (SmCo), alnico (AlNiCo), and ferrite permanent magnet material (Ferrite), etc. By setting the permanent magnet magnetic member, the accuracy of the feedback obtained by the sensor 235 is ensured, thereby further improving the use stability of the motor clutch mechanism.

[0058] Based on the above embodiments, as Figure 2 shown, in the drive assembly 200, a first drive wheel 240 and a second drive wheel 250 are further arranged. The first drive wheel 240 and the second drive wheel 250 are rotatably installed on a preset structure of the drive housing 220, and the first drive wheel 240 and the second drive wheel 250 are meshed through gears and rotate synchronously. Moreover, the first drive wheel 240 is synchronously meshed and rotated with the motor gear 233. When the above-mentioned motor group 230 starts to start, the motor 231 rotates, driving the motor gear 233 to rotate, and then causing the first drive wheel 240 and the second drive wheel 250 to rotate synchronously.

[0059] In another feasible embodiment of the present invention, the second drive wheel 250 and the motor gear 233 can be connected and fixed through gear meshing. During the actual manufacturing process, the position adjustment between the first drive wheel 240 and the second drive wheel 250 can be controlled by an electronic chip. Since the number of tooth grooves provided on the first drive wheel 240 and the second drive wheel 250 is different, the rotation speeds when the first drive wheel 240 is connected to the motor gear 233 and when the second drive wheel 250 is connected to the motor gear 233 are different. By adjusting the different connection relationships of the above-mentioned first drive wheel 240, second drive wheel 250, and motor gear 233, the conversion of different speed ratios can be achieved.

[0060] Furthermore, the drive assembly further includes a compression push plate 260. The compression push plate 260 is a rectangular member, and a long strip-shaped through groove, namely an eccentric groove 261, is arranged in the horizontal direction. Correspondingly, an eccentric shaft is arranged on one side of the second drive wheel 250 facing the compression push plate 260, that is, the columnar structure protruding from the right side of the second drive wheel 250 shown in the figure. The size of the eccentric shaft is adapted to that of the eccentric groove 261. When the second drive wheel 250 rotates, the eccentric shaft moves along the direction in which the eccentric groove 261 is arranged in the eccentric groove 261. In this state, the compression push plate 260 is forced to displace in the up and down directions.

[0061] In cooperation with the above structure, a sliding groove 211 is provided on the pusher 210. The shape of the sliding groove 211 is adapted to the shape of the compression push plate 260, and the dimension in the length direction is greater than the dimension of the compression push plate 260. Therefore, when the compression push plate 260 is driven by the second driving wheel 250 to move, the actual movement path of the compression push plate 260 is to slide within the sliding groove 211. Preferably, to ensure smooth and stable operation of the above structure, a return spring 270 is further provided within the sliding groove 211. One end of the return spring 270 is fixedly connected to one side of the structure of the compression push plate 260, and the other end is fixed within the sliding groove 211. When the compression push plate 260 slides within the sliding groove 211, the compression end plate 211 squeezes the return spring 270, causing the return spring 270 to compress and accumulate elastic potential energy. When the driving force received by the second driving wheel 250 disappears, the return spring 270 releases the elastic potential energy and pushes the compression end plate 211 back to the initial position, thereby achieving the effect of the pusher 210 being reciprocally pushed by the compression end plate 211.

[0062] On the other hand, in another feasible embodiment of the present invention, as Figure 4 shown, the clutch assembly 300 includes a shaft sleeve 330, an elastic clutch member 310, an elastic tooth-pushing member 320, and a handle rotating shaft. The above structures cooperate with each other to perform related operations of unlocking or locking when the handle rotating shaft rotates.

[0063] Specifically, the elastic clutch member 310 includes a clutch pin 311, a clutch spring 312, and a mating member 313. The clutch pin 311 is sleeved and connected with a clutch hole 331 provided on the shaft sleeve 330, and the clutch pin 311 freely slides inside the clutch hole 331. The clutch spring 312 is arranged inside the clutch hole 331. One end of the clutch spring 312 is fixedly connected to the clutch pin 311, and the other end is fixed to the planar structure inside the clutch hole 331. When the clutch pin 311 slides inside the clutch hole 331, the clutch spring 312 is compressed, so that the clutch spring 312 accumulates a certain amount of elastic potential energy. After the external force applied to the clutch pin 311 disappears, the clutch spring 312 releases its own elastic potential energy and pushes the clutch pin 311 towards the outside of the clutch hole 331, thereby achieving reset. A mating member 313 is further provided at the upper end of the clutch pin 311. The shape of the mating member 313 is adapted to the shape of the pushing portion of the pusher 210. The mating member 313 is fixedly arranged at the upper end of the clutch pin. When the pusher 210 and the mating member 313 cooperate with each other, a linkage state is achieved, that is, the pusher 210 pushes the clutch pin 311 to move.

[0064] The elastic tooth shifting member 320 includes a shifting wheel tooth 321, a shifting wheel column 322 and a tooth shifting spring 323. An installation hole 321b is provided on the shifting wheel tooth 321, and the size of the installation hole 321b is adapted to the size of the shifting wheel column 322. The shifting wheel tooth 321 is fixed at a preset position of the bushing 330 through the shifting wheel column 322. A tooth shifting spring 323 is also provided on the shifting wheel column 322, and the tooth shifting spring 323 abuts against the shifting wheel tooth 321 to achieve the effect of elastic reset. The tooth shifting spring 323 extends two bent arms, which are hidden in the groove on the side of the shifting wheel tooth 321 with the shifting wheel column 322 as the center. One extending arm is limited by the edge of the groove of the shifting wheel tooth 321, and the other extending arm is limited by the edge of the hole on the side of the bushing 330. The shifting wheel 321 is pre-compressed by the tooth shifting spring 323, and its side arc surface fits against the limiting arc surface of the bushing 330;

[0065] On the other hand, the handle rotating shaft includes a first handle rotating shaft 341 and a second handle rotating shaft 342. The structures of the first handle rotating shaft 341 and the second handle rotating shaft 342 are the same and are relatively sleeved inside the bushing 330. Among them, a first protrusion 341a is provided on the first handle rotating shaft 341, and a second protrusion 342a is provided on the second handle rotating shaft 342. The first protrusion 341a and the second protrusion 342a are arranged opposite to each other and rotate synchronously. In other parts of the above embodiment, one end of the handle rotating shaft has an outer circle and inner square counterbore structure, and an arc-shaped card slot is provided on the outer side wall of the outer circle. The depth of the card slot is greater than the radius of the arc, which is used to install a round snap ring; the other end has a cylindrical structure above the outer circle to accommodate the wall thickness of the inner square hole, and a small round shaft is provided at the upper end, and an arc-shaped protrusion is provided on one side. The middle of it is connected to the small round shaft structure to ensure strength, and the two open planes are respectively engaged with the clutch pin 311 and the shifting wheel tooth 321 when the outer handle shaft rotates.

[0066] The above-mentioned round snap ring is designed with a single-turn round axis line, and it has a certain opening space for elastic deformation reservation during disassembly and installation.

[0067] During actual use, the first handle rotating shaft 341 is respectively installed in the receiving cavities at both ends of the bushing 330 through snap rings. The second handle rotating shaft 342 and the clutch pin 311 are in square shaft and hole mating for synchronous linkage. The first handle rotating shaft 341 and the clutch pin 311 are in round shaft and hole positioning and can move relative to each other. The clutch spring 312, the clutch pin 311 and the fitting 313 are sequentially installed in the stepped hole on the side of the bushing 330. The clutch hole 331 is mechanically pressed and deformed to close the mouth to fix the clutch pin 311 to ensure that it will not fall out of the hole of the clutch pin 311. The dial wheel teeth 321 and the dial tooth spring are installed in the opening on the other side of the clutch pin 311. The small end of the dial wheel column 322 sequentially passes through the through holes of the clutch pin 311, the dial wheel teeth 321 and the dial tooth spring 323, and is limited by the stepped surface of the dial wheel column 322. When unlocking, the end of the clutch pin 311 is stressed to compress the clutch spring 312 so that the end of the clutch pin 311 is flush with the clutch hole 331. At this time, according to the opening direction, the first handle rotating shaft 341 rotates clockwise or counterclockwise. The first protrusion 341a on the first handle rotating shaft 341 presses the clutch pin 311, driving the clutch pin 311 to perform a synchronous rotational movement. The clutch pin 311 drives the corresponding parts through the structural bosses provided at both ends to achieve unlocking.

[0068] When the clutch pin 311 and the clutch spring 312 are in the released state, the first handle rotating shaft 341 is in the free state. At this time, when the first handle rotating shaft 341 is rotated, only one direction of clockwise or counterclockwise can drive the clutch pin 311 to achieve synchronous movement by the first handle rotating shaft 341 engaging the dial wheel teeth 321. When the first handle rotating shaft 341 rotates in the opposite direction, it can compress the dial wheel teeth 321 to swing outward, realizing the 360° free rotation of the first handle rotating shaft 341. When the second handle rotating shaft 342 rotates counterclockwise or clockwise, the corresponding parts are driven to move through the first protrusion 341a and the second protrusion 342a provided at both ends of the clutch pin 311 to achieve unlocking and locking.

[0069] Through the mutual cooperation between the driving component 200 and the clutch component 300 in the above embodiments, that is, the linkage cooperation between the pushing member 210 and the clutch pin 311, different states of opening or closing of the electronically managed electronic lock are realized.

[0070] Based on the above embodiments, the present invention further provides an intelligent door lock, which includes the motor clutch mechanism in the above embodiments. The motor clutch mechanism is provided with a driving component inside the housing of the motor clutch mechanism, and at the same time, a clutch component is arranged side by side. The pushing member provided on the driving component abuts against the clutch pin provided on the clutch component. When the driving component is started, the pushing member pushes the clutch pin to achieve the effect of opening or locking. The structure of the present invention is stable and has an extremely long service life, and can meet the requirements of high stability in electronic door locks.
