Description
Technical Field
[0001] The present invention relates to the technical field of motors, and in particular to a motor drive structure. Background Art
[0002] The existing motor drive structure acts on the mahjong machine. As a cultural and entertainment product widely used by people, the mahjong machine not only brings entertainment and leisure to people, but also exercises people's brains, eyes, and hands, which is beneficial to people's health. The working principle of the mahjong machine is that the cards with the backs of the mahjong tiles facing up are attracted by the magnetic ring on the shuffle barrel, rotate with the magnetic ring and are sent to the conveying trough, and are pushed into piles by the stacking motor at the head of the machine and pushed away by the chain rod. The cards without magnetism on the front continue to rotate on the disk (single-mouth machine principle). With the development of technology, the types of mahjong machines are constantly improved and innovated. The existing mahjong machine is equipped with multiple motor electronic control structures, including a motor push-up structure assembly. The motor push-up structure uses the motor itself as the driving source. During the rotation of the motor, the driving structure is driven by the rotation of the motor to lift the push-up plate. During use, we found that the existing structure does not have the ability to provide self-protection for the motor. During normal play, the player's items are easy to fall on the push-up plate during the descent of the push-up plate. During the rise of the push-up plate, the push-up plate and mahjong will be stuck on the table and cannot rise. The existing push-up plate driving structure generally uses two meshing gears as transmission. Drive gears are meshed on the sides of the two gears. A rocker arm is installed on each drive gear, and the rocker arm is in contact with the bottom of the push-up plate. When the push-up plate cannot rise smoothly, reverse torque will be generated between the gears, which will not only damage the motor, but also cause the gears to hit each other, causing the rocker arm to be misaligned. The push-up plate cannot reach the preset normal position when it rises or falls. For this reason, we propose a motor driving structure. Summary of the invention

DETAILED DESCRIPTION
[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0016] See also Figure 1-12The present invention provides a technical solution: a motor drive structure, including a casing 1, a motor assembly 2 is fixedly installed on the casing 1, a rotating shaft 11 is fixedly connected to the output shaft of the motor assembly 2, a transmission gear 6 is detachably sleeved on the outer ring of the rotating shaft 11, a first driving gear 5 is rotatably connected to one side of the casing 1, the first driving gear 5 and the transmission gear 6 are meshed for transmission, a second driving gear 8 is rotatably connected to the other side of the casing 1, a transition gear 7 is meshed for transmission between the second driving gear 8 and the transmission gear 6, a plurality of second magnets 14 are equidistantly installed on the outer ring of the rotating shaft 11 in an annular shape, a connecting sheath 12 is fixedly installed on the inner ring of the central axis of the transmission gear 6, a plurality of first magnets 13 are fixedly installed on one end of the connecting sheath 12, the first magnet 13 and the second magnet 14 have opposite magnetic poles and are attracted to each other, a rocker arm 15 is connected to one side of the first driving gear 5 and the second driving gear 8, and sliding Rod 3, a mounting cover plate 4 is slidably connected between the two sliding rods 3. When the motor assembly 2 rotates, the second magnet 14 is driven to rotate. Since the second magnet 14 and the first magnet 13 attract each other, the output shaft of the motor assembly 2 drives the rotating shaft 11 to rotate, so that the rotation of the rotating shaft 11 drives the second magnet 14 to rotate. When the second magnet 14 rotates, it can drive the first magnet 13 attracted thereto to rotate, so that the connecting sheath 12 rotates. The rotation of the connecting sheath 12 can cause the transmission gear 6 to rotate. The rotation of the transmission gear 6 causes the transition gear 7, the first driving gear 5 and the second driving gear 8 to rotate in turn, wherein the second driving gear 8 and the transmission gear 6 have the same direction of rotation, and the transmission gear 6 and the first driving gear 5 have opposite directions of rotation. Since the first driving gear 5 and the second driving gear 8 have the same structure and a rocker arm 15 is installed on the outside, as shown in the attached figure Figure 2 As shown, when the first driving gear 5 rotates counterclockwise, the second driving gear 8 rotates clockwise, and the mounting cover 4 is in an ascending stage. When a foreign object falls into the top of the mounting cover 4 and contacts the top shell of the mahjong machine, the motor assembly 2 is still outputting continuously, so the foreign object blocks the mounting cover 4 from rising, causing downward pressure on the mounting cover 4. Therefore, in this process, if the pressure exceeds the magnetic force of attraction between the second magnet 14 and the first magnet 13, the second magnet 14 and the first magnet 13 will separate, so that the rotating shaft 11 is in an idling process, which protects the motor assembly 2 and increases its service life.
[0017] Furthermore, a ratchet 19 is fixedly connected to the first driving gear 5, and the other end of the connecting sheath 12 is fixedly connected to a first bevel gear 23, one side of the first bevel gear 23 is transmission-connected to a second belt 26, one end of the second belt 26 is connected to a bearing, and an inner ring of the bearing is fixedly connected to an inverted ratchet 20, and the outer ring surfaces of the ratchet 19 and the inverted ratchet 20 are both provided with convex teeth, and the ratchet 19 and the inverted ratchet 20 are driven by the convex teeth, and a rotating disk 18 is fixedly connected to the middle of the inverted ratchet 20, and the outer ring of the rotating disk 18 is sleeved with a first belt 17, and one end of the first belt 17 is connected to a rope reel 16; both ends of the top of the casing 1 are fixedly connected to a suspension frame, and each A gear plate 10 is rotatably connected to a suspension frame, and a rack 9 is slidably connected to the two suspension frames. The top of the rack 9 is in contact with the casing 1, and the rack 9 and the gear plate 10 are meshed for transmission. One end of the rack 9 is fixedly connected to a protruding rod 901, and one end of the protruding rod 901 is fixedly connected to a traction rope 903. A pair of limiting rollers 905 are fixedly connected to one side of the casing 1. The traction rope 903 is in contact with the surface of the limiting rollers 905 and is wound on the rope winding drum 16. A fixing plate 904 is provided on one side of the casing 1 near the traction rope 903. A first spring 902 is fixedly connected to one side of the fixing plate 904, and the first spring 902 is sleeved on the outside of the traction rope 903; each gear plate 10 is provided with a fixing plate 904, and a fixing plate 904 is fixedly connected to one side of the fixing plate 904. The first spring 902 is sleeved on the outside of the traction rope 903. They are all fixedly connected with an internal threaded rotating cylinder 1001, and the inner circle of the internal threaded rotating cylinder 1001 is rotatably connected with a screw rod 1002, and the bottom of the screw rod 1002 is fixedly connected with a limit plate 1003, and the limit plate 1003 is used to limit the rotation of the rocker arm 15 after it is lowered; the rotation time of the motor assembly 2 in the device is limited. For example, when the device is in normal use, the cover plate 4 is installed to rotate the motor assembly 2 from the lowest part of the rocker arm 15 to the highest point. Generally, this time is usually about 3 seconds. During the rotation of the motor assembly 2, after the second magnet 14 and the first magnet 13 are separated, the torsion of the shaft 11 will not drive the connecting sheath 12 to rotate, because This connecting sheath 12 has no rotation tendency, the transmission gear 6 does not rotate, and there is still pressure on the installation cover 4, so foreign matter is difficult to be easily taken out. The downward pressure on the installation cover 4 will cause the rocker arm 15 to drop, the first drive gear 5 and the second drive gear 8 to reverse, the second magnet 14 and the first magnet 13 turn in opposite directions, and the installation cover 4 drops. During the process of the motor assembly 2 not rotating, the ratchet 19 drives the reverse ratchet 20 to rotate, and the rotation of the reverse ratchet 20 drives the first belt 17 to rotate, allowing the rope reel 16 to recycle the traction rope 903, and the traction rope 903 drives the protruding rod 901 to the attached Figure 2The right side movement shown in the figure causes the rack 9 to move, causing the gear plate 10 to rotate. During the rotation of the gear plate 10, the screw rod 1002 rises, driving the limit plate 1003 to rise, so that the limit plate 1003 blocks the rotation path of the rocker arm 15, preventing foreign matter located on the installation cover plate 4 from falling into the interior of the entire machine, thereby causing failure of other components of the equipment. During this process, the equipment is in operation until the motor assembly 2 stops rotating. During this period, the foreign matter is taken out manually, and the second magnet 14 and the first magnet 13 are in an attractive state again, and then again The motor assembly 2 is turned on to rotate, and the equipment resumes normal operation. The installation cover 4 is lowered, which is also conducive to removing foreign objects thereon. After the equipment resumes normal operation, the first bevel gear 23 rotates, and the second belt 26 rotates. The second belt 26 is connected to the reverse click ratchet 20 through the bearing. When the motor assembly 2 is in normal operation, the inner ring of the bearing and the reverse click ratchet 20 are fixedly connected, the bearing is in idle rotation, and the first spring 902 is reset, the rack 9 and the gear plate 10 are reset, and the screw rod 1002 is lowered so that the limit plate 1003 does not interfere with the activity trajectory of the rocker arm 15.
[0018] Specifically, there is a gap between two adjacent convex teeth on the surface of the ratchet 19 and the reverse ratchet 20, and each convex tooth has an inclined surface with an angle formed by the tangents of the ratchet 19 and the reverse ratchet 20. A one-way opening and closing limiting block 2001 is rotatably connected to each convex tooth of the reverse ratchet 20. The side surface of the limiting block 2001 and the inclined surface remain in the same plane, so that the ratchet 19 and the reverse ratchet 20 can rotate in a single direction. When the ratchet 19 rotates, the top of the convex tooth on the ratchet 19 is embedded in the side surface of the convex tooth on the reverse ratchet 20, as shown in the attached figure. Figure 6-8As shown, when the ratchet 19 rotates counterclockwise, the reverse ratchet 20 does not rotate, wherein the limiting block 2001 is made of a magnet. Due to its own gravity, the limiting block 2001 turns clockwise on the convex teeth of the reverse ratchet 20 at a certain angle and then stops turning. At this time, the limiting block 2001 is still on the rotation path of the convex teeth of the ratchet 19. The material of the convex teeth of the ratchet 19 is a magnetic material. The convex teeth of the ratchet 19 and the limiting block 2001 have the same magnetic poles. Because the limiting block 2001 needs to bypass the rotation path of the convex teeth of the ratchet 19, The transmission of the ratchet 19 and the reverse ratchet 20 fails, so a torsion spring (not shown) is also installed between the limiting block 2001 and the convex teeth of the reverse ratchet 20. The torsion spring does not intervene in the process of the limiting block 2001 turning over by its own gravity, but waits until the convex teeth of the ratchet 19 are close to the limiting block 2001 and have not yet touched it during the counterclockwise rotation. Under the effect of the repulsion of the same poles, the side of the limiting block 2001 is affected by the magnetic force, and then turns over and compresses the torsion spring, so that the limiting block 2001 is allowed to rotate during the rotation of the convex teeth of the ratchet 19. 01 leaves the rotation path of the convex teeth of the ratchet 19 and does not drive the reverse click ratchet 20 to rotate. Even if the reverse click ratchet 20 rotates, it is only a very small shake. After the convex teeth of the ratchet 19 rotate counterclockwise and pass over the limiting block 2001, the torsion spring drives the limiting block 2001 to reset, and the inertia of the torsion spring reset will drive the reverse click ratchet 20 to rotate slightly, which can offset the slight shake of the reverse click ratchet 20. When the ratchet 19 rotates clockwise, the convex teeth of the ratchet 19 are located below the limiting block 2001 and are connected to the reverse click ratchet 20 by the same polarity. According to the principle of repulsion, the reverse ratchet 20 is driven to rotate counterclockwise through the limiting block 2001, so that the ratchet 19 and the reverse ratchet 20 cooperate with each other to rotate, to prevent the ratchet 19 and the reverse ratchet 20 from transmitting to each other during the normal operation of the equipment so that the limit plate 1003 rises and interferes with the movement of the rocker arm 15; that is, the counterclockwise rotation of the ratchet 19 will not control the rotation of the reverse ratchet 20, and the clockwise rotation of the ratchet 19 can control the counterclockwise rotation of the reverse ratchet 20, thereby controlling the normal operation of the rotating disk 18, the first belt 17 and the rope winding disk 16.
[0019] Furthermore, a rotating rod 25 is rotatably suspended in the middle of one side of the casing 1, and a second bevel gear 24 is fixedly connected to the top of the rotating rod 25, and the second bevel gear 24 and the first bevel gear 23 are meshed for transmission. A third bevel gear 2501 is fixedly connected to the bottom of the rotating rod 25, and a worm 28 is rotatably connected to the bottom of one side of the casing 1, and one end of the worm 28 is fixedly connected to a fourth bevel gear 29, and the third bevel gear 2501 is meshed with the fourth bevel gear 29. A reciprocating screw 22 is rotatably connected to the other side of the bottom of the casing 1, and a worm wheel 27 is fixedly mounted on the reciprocating screw 22, and the worm wheel 27 and the worm 28 are meshed for transmission. A booster block 21 is threadedly connected to the reciprocating screw 22, and the side of the booster block 21 is in contact with the first driving gear 5, and its bottom is slidably connected to the casing 1. When the motor assembly 2 is in normal operation, it can be driven by the first bevel gear 2 3 drives the second bevel gear 24 to rotate, so that the rotating rod 25 drives the third bevel gear 2501 to rotate, and the fourth bevel gear 29 drives the worm 28 to rotate, so that the worm wheel 27 rotates and drives the reciprocating screw 22 to rotate, and finally the booster block 21 moves back and forth on the surface of the first driving gear 5. When the first driving gear 5 drives the rocking arm 15 to be in the ascending stage, the booster block 21 is at the leftmost side of the casing 1 and moves to the rightmost side of the casing 1, and is in the boosting process. When the rocking arm 15 rotates to the highest point and returns to the lowest point, the booster block 21 is also in the return process. The booster block 21 fits the surface of the first driving gear 5 to prevent the first driving gear 5 from driving the rocking arm 15 to descend too fast, thereby causing the first driving gear 5 to rotate at an unstable speed, resulting in the shaking of the installation cover 4 during the lifting process.
[0020] Furthermore, arc grooves are provided on the first driving gear 5 and the second driving gear 8, and the inner circle of each arc groove is provided with a through groove, and a second spring 30 is installed equidistantly inside each through groove, and multiple second springs 30 are arranged in a fan shape, and one end of each second spring 30 is fixedly connected to an extrusion block 31, and the top of each through groove has a folded edge close to the extrusion block 31. When the foreign matter above the mounting cover 4 is too heavy, it may cause the rocker arm 15 to descend too fast, causing it to get stuck between the mounting cover 4 and the device body. Therefore, when the foreign matter is too heavy, the rocker arm 15 will first contact the extrusion block 31 and then pass over the extrusion block 31, thereby utilizing the friction and load of the extrusion block 31 to reduce the instantaneous descending speed of the rocker arm 15, and the elastic coefficients of the multiple second springs 30 are gradually increased to overcome the pressure of the rocker arm 15 and the heavy objects above the mounting cover 4.
[0021] Elastic structures are installed at both ends of the top of the mounting cover plate 4, and the elastic structure includes pin blocks sliding on both ends of the mounting cover plate 4. The pin blocks are slidably connected to the rocker arm 15, and a reset spring is connected to the side of each pin block. Two threaded holes are opened on one side of the top of the mounting cover plate 4 for installing the push plate structure. The pin blocks are movably connected to the mounting cover plate 4 for contacting the rocker arm 15. The reset spring keeps the mounting cover plate 4 and the rocker arm 15 inseparable, thereby improving the lifting and lowering stability of the mounting cover plate 4.
