Technical Field
[0001] The present invention relates to the technical field of door lock motors, in particular to a door lock motor with good stability and easy maintenance. Background Art
[0002] Door lock motors, also known as electric door locks, are commonly used in car doors, smart doors, and appliances with intelligent opening and closing functions. The principle of door lock motors is to use an electric motor to drive the lock cylinder to move in order to open and close the lock. Compared with mechanical locks, door lock motors are safer and more stable, and can be made smaller in size, which makes the use of door lock motors more extensive.
[0003] Common door lock motors on the market are usually unable to effectively detect whether the door lock is closed. If the door lock is not closed properly, the electric motor drives the lock cylinder to move and cannot enter the lock hole, which will cause damage to the door lock motor. At the same time, a door lock that is not closed properly will also cause a safety hazard.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a door lock motor with good stability and easy maintenance is proposed. Summary of the Invention

[0008] Furthermore, the cover plate is fixedly connected to the electric motor, and the cover plate is engaged with the drive box via a clamping column.
[0009] Furthermore, the output shaft is sleeve-connected to the shaft sleeve, and the outer contour size of the shaft sleeve is consistent with the inner contour size of the docking groove.
[0010] Furthermore, the lifting assembly includes a lifting rod, a slide groove, a first spring, a screw slider, a locking tooth, a sleeve, a second spring, a sound-controlled alarm, a pressure-sensitive sensor, a guide rail and a tooth groove. A slide groove is provided on the inner side of the lifting rod, and the first spring is connected to the inner two sides of the slide groove. The outer end of the first spring is connected to the screw slider, and the end of the lifting rod is connected to the locking tooth. The right outer end of the lifting rod is connected to the sleeve, and the second spring is provided on the inner two sides of the sleeve. The outer end of the sleeve is connected to the sound-controlled alarm, and the pressure-sensitive sensor is provided on the inner two sides of the sleeve.

[0011] Furthermore, the lifting rod and the locking tooth are integrated, and the locking tooth is engaged with the tooth groove.
[0012] Furthermore, the lifting rod and the guide rail are distributed vertically, and the sound-controlled alarm slides on the outer end of the guide rail.
[0013] Furthermore, when the first oblique block and the second oblique block are brought together, the magnet and the magnetic conductive plate fit together, and the second oblique block and the lock core are integrated.
[0014] Furthermore, the sliding rod assembly includes a rod body, a displacement groove, a third spring and a clamping block.

[0015] Furthermore, the card block is magnetically attracted to the magnetic conductive plate (11), and the size of the card block (1404) matches the size of the card slot (12).
[0016] The present invention provides a door lock motor with good stability and easy maintenance, which has the following beneficial effects:
[0017] 1. After the first bevel block and the second bevel block of the present invention are completely fitted together, the magnet at the outer end of the first bevel block will contact the magnetic conductive plate at the outer end of the second bevel block. At this time, the second bevel block moves to the position where the slot at the outer end of the rod overlaps with the block. After the magnet contacts the magnetic conductive plate, its magnetic force can be conducted to the magnetic conductive plate, and the end of the magnetic conductive plate can extend into the slot. When the slot and the block overlap, the magnetic force can attract the block, which enables the block to pull the third spring to displace inside the displacement slot and get stuck into the slot. Through the engagement of the slot and the block, the positioning stability of the second bevel block on the surface of the rod body can be effectively guaranteed, which can prevent the second bevel block from being displaced by lateral force (shaking force or malicious prying) and causing the lock core to rebound, which can greatly improve the stability of the device.
[0018] When the door is not locked, the first bevel block and the second bevel block are in a state of being unable to move. At this time, the first bevel block continues to move upward. Since the second bevel block and the lock core are in an immovable state at this time, the reaction force is transmitted to the first bevel block itself, which enables the reaction force to be transmitted to the lifting rod. After the lifting rod is subjected to the reaction force, it can squeeze the first spring and the second spring to move rightward. In the process of the lifting rod moving rightward, the locking tooth at the end of the lifting rod can be stuck in the tooth groove to interlock, thereby preventing the first bevel block from moving upward. At the same time, in the process of the lifting rod moving rightward, the pressure sensitive sensor can be squeezed. After receiving the pressure signal, the pressure sensitive sensor will stop driving the electric motor and make the sound-controlled alarm sound an alarm, thereby reminding the user that the door lock is not locked. This can effectively avoid the situation that the lock core and the lock strike are not aligned and the electric motor continues to apply force to cause damage to the equipment. At the same time, the safety of the equipment can be effectively improved by detecting that the door lock is not locked.
[0019] 3. When installing the electric motor of the present invention, the cover plate is first fixed to the end of the electric motor, and a shaft sleeve is sleeved on the output shaft at the front end of the electric motor. When the electric motor is inserted into the drive box, the clamping column at the bottom end of the end cover plate can be engaged with the through groove of the drive box to ensure the fixed stability of the electric motor in the drive box, and the output shaft and the shaft sleeve can be inserted into the docking groove of the active swivel seat to realize power transmission. Because the drive box and the frame are two separate spaces, and the electric motor drive is transmitted to the driven swivel seat in the frame through the transmission chain, this allows the electric motor to be separated from the equipment body. When the electric motor is damaged, the staff only needs to pull out the cover plate to remove the electric motor and the shaft sleeve from the inside of the drive box to realize rapid replacement of the electric motor, which improves the maintenance convenience of the equipment.

The lock core 10 is integrated with the slide bar 1401, and the second bevel block 9 is put together, and the second bevel block 9 is integrated with the lock core 10. The slide bar assembly 14 includes a rod body 1401, a displacement groove 1402, a third spring 1403 and a clamping block 1404.

The outer end of the third spring 1403 is connected to the clamping block 1404. The clamping block 1404 is magnetically attracted to the magnetic plate 11, and the size of the clamping block 1404 matches the size of the clamping slot 12.
[0029] The specific operation is as follows: when the door lock motor is running, the electric motor 202 works to make the output shaft 205 drive the active swivel seat 207 to rotate. When the active swivel seat 207 rotates, the kinetic energy can be transmitted to the driven swivel seat 4 through the transmission chain 3, which enables the driven swivel seat 4 to drive the lead screw 5 to rotate. During the rotation of the lead screw 5, the lead screw slider 604 can be lifted to achieve the upward displacement of the lifting rod 601. During the upward movement of the lifting rod 601, the first inclined block 7 and the second inclined block 9 can be fitted together. Thanks to the shape characteristics of the first inclined block 7 and the second inclined block 9, when the first inclined block 7 continues to move upward, it can push the second inclined block 9 to slide to the left at the outer end of the rod body 1401 and stretch the reset spring 13. During the left displacement of the second inclined block 9, The lock core 10 is extended out of the frame 1 and interlocked with the lock catch to achieve the locking of the lock, and the reverse rotation of the electric motor 202 can make the first bevel block 7 move down and separate from the second bevel block 9. At this time, the second bevel block 9 will rebound due to the reset of the reset spring 13 to achieve the opening of the lock. After the first bevel block 7 and the second bevel block 9 are fully fitted, the magnet 8 at the outer end of the first bevel block 7 will contact the magnetic plate 11 at the outer end of the second bevel block 9. At this time, the second bevel block 9 moves to the position where the slot 12 at the outer end of the rod body 1401 coincides with the block 1404. After the magnet 8 contacts the magnetic plate 11, its magnetic force can be conducted to the magnetic plate 11, and the end of the magnetic plate 11 can extend into the slot 12. When the slot 12 coincides with the block 1404, the magnetic force can attract the block 1404. The locking block 1404 can pull the third spring 1403 to move inside the displacement groove 1402 and be stuck in the locking groove 12. The engagement of the locking groove 12 and the locking block 1404 can effectively ensure the positioning stability of the second bevel block 9 on the surface of the rod body 1401, which can prevent the second bevel block 9 from being displaced by the lateral force (shaking force or malicious prying) and causing the lock cylinder 10 to rebound, which can greatly improve the stability of the device. In addition, if the lock cylinder 10 and the lock buckle do not coincide but the electric motor 202 is started (the door lock is not closed properly), the second bevel block 9 and the lock cylinder 10 will first move to the left and contact the obstacle. At this time, the first bevel block 7 continues to move upward. Because the second bevel block 9 and the lock cylinder 10 are in an immovable state at this time, the reaction force will be transmitted to the first The inclined block 7 itself allows the reaction force to be transmitted to the lifting rod 601. After the lifting rod 601 is subjected to the reaction force, it can squeeze the first spring 603 and the second spring 607 to move to the right. During the process of the lifting rod 601 moving to the right, the locking tooth 605 at the end thereof can be stuck in the tooth groove 611 to interlock, thereby preventing the first inclined block 7 from moving upward. At the same time, during the process of the lifting rod 601 moving to the right, it can squeeze the pressure sensitive sensor 609. After receiving the pressure signal, the pressure sensitive sensor 609 will pause the driving of the electric motor 202 and make the sound-controlled alarm 608 sound an alarm, thereby reminding the user that the door lock is not closed tightly. This can effectively prevent the lock cylinder 10 and the lock buckle from coinciding and the electric motor 202 from continuously applying force to cause damage to the equipment.At the same time, by detecting whether the door lock is not closed, the safety of the equipment can be effectively improved. The electric motor 202 is placed inside the drive box 201. When the electric motor 202 is installed, the cover plate 203 is first fixed to the end of the electric motor 202, and the shaft sleeve 206 is sleeved on the output shaft 205 at the front end of the electric motor 202. When the electric motor 202 is inserted into the drive box 201, the clamping column 204 at the bottom end of the end cover plate 203 can be engaged with the through groove of the drive box 201 to ensure the fixed stability of the electric motor 202 in the drive box 201, and the shaft sleeve 206 on the output shaft 205 can be engaged with the shaft sleeve 206. 206 can be inserted into the docking slot 208 of the active swivel seat 207 to achieve power transmission. Because the drive box 201 and the frame 1 are two separate spaces, and the drive of the electric motor 202 is transmitted to the driven swivel seat 4 in the frame 1 through the transmission chain 3, the electric motor 202 can be separated from the device body. When the electric motor 202 is damaged, the staff only needs to pull out the cover plate 203 to remove the electric motor 202 and the shaft sleeve 206 from the inside of the drive box 201 to achieve rapid replacement of the electric motor 202, which makes the maintenance convenience of the equipment more convenient.
[0030] In summary, the door lock motor with good stability and easy maintenance is used. First, when the door lock motor is running, the electric motor 202 works, which can make the output shaft 205 drive the active swivel seat 207 to rotate. When the active swivel seat 207 rotates, it can transfer kinetic energy to the driven swivel seat 4 through the transmission chain 3, which makes the driven swivel seat 4 drive the lead screw 5 to rotate. During the rotation of the lead screw 5, it can lift the lead screw slider 604 to achieve the upward displacement of the lifting rod 601. During the upward movement of the lifting rod 601, it can make the first inclined block 7 Fitting with the second bevel block 9, thanks to the shape characteristics of the first bevel block 7 and the second bevel block 9, when the first bevel block 7 continues to move upward, it can push the second bevel block 9 to slide leftward on the outer end of the rod body 1401 and stretch the return spring 13. In the process of the second bevel block 9 moving leftward, the lock core 10 can be extended out of the frame 1 and interlocked with the lock catch to achieve the locking of the lock. By the reverse rotation of the electric motor 202, the first bevel block 7 can be moved downward and separated from the second bevel block 9. At this time, the second bevel block 9 will rebound due to the reset of the return spring 13 to achieve the opening of the lock.
[0031] Then, after the first inclined block 7 and the second inclined block 9 are completely fitted together, the magnet 8 at the outer end of the first inclined block 7 will contact the magnetic plate 11 at the outer end of the second inclined block 9. At this time, the second inclined block 9 moves to the position where the slot 12 at the outer end of the rod body 1401 coincides with the block 1404. After the magnet 8 contacts the magnetic plate 11, its magnetic force can be conducted to the magnetic plate 11, and the end of the magnetic plate 11 can extend into the slot 12. When the slot 12 coincides with the block 1404, the magnetic force can be applied to the block. 1404 is attracted, which enables the clamping block 1404 to pull the third spring 1403 to move inside the displacement groove 1402 and be clamped into the clamping groove 12. The engagement between the clamping groove 12 and the clamping block 1404 can effectively ensure the positioning stability of the second bevel block 9 on the surface of the rod body 1401, thereby preventing the second bevel block 9 from being displaced by a lateral force (shaking force or malicious prying) and causing the lock cylinder 10 to rebound, thereby greatly improving the stability of the device.
[0032] Then, if the lock cylinder 10 and the lock catch do not overlap but the electric motor 202 is started (the door lock is not closed properly), the second bevel 9 and the lock cylinder 10 will first move to the left and contact the obstacle. At this time, the first bevel 7 continues to move upward. Since the second bevel 9 and the lock cylinder 10 are in an immobile state at this time, the reaction force will be transmitted to the first bevel 7 itself, which enables the reaction force to be transmitted to the lifting rod 601. After receiving the reaction force, the lifting rod 601 can squeeze the first spring 603 and the second spring 607 to move to the right. In the process of the lifting rod 601 moving to the right, the locking gear at the end of the lifting rod 601 605 can be inserted into the tooth groove 611 to interlock, thereby preventing the first inclined block 7 from moving upward. At the same time, the lifting rod 601 can squeeze the pressure sensitive sensor 609 during the rightward movement. After receiving the pressure signal, the pressure sensitive sensor 609 will stop driving the electric motor 202 and make the sound-controlled alarm 608 sound an alarm, thereby reminding the user that the door lock is not tightly closed. This can effectively prevent the lock cylinder 10 and the lock catch from not coinciding with the electric motor 202 continuously applying force, thereby causing damage to the device. At the same time, by detecting that the door lock is not tightly closed, the safety of the device can be effectively improved.
[0033] Finally, when installing the electric motor 202, first fix the cover plate 203 to the end of the electric motor 202, and put the shaft sleeve 206 on the output shaft 205 at the front end of the electric motor 202. When the electric motor 202 is inserted into the driving box 201, the clamping column 204 at the bottom end of the cover plate 203 can be engaged with the through groove of the driving box 201 to ensure the fixed stability of the electric motor 202 in the driving box 201, and the output shaft 205 and the shaft sleeve 206 can be inserted into the docking groove 208 of the active rotating seat 207. In order to realize power transmission, the driving box 201 and the frame 1 are two separate spaces, and the drive of the electric motor 202 is transmitted to the driven swivel seat 4 in the frame 1 through the transmission chain 3, which makes the electric motor 202 separable from the equipment body. When the electric motor 202 is damaged, the staff only needs to pull out the cover plate 203 to pull out the electric motor 202 and the shaft sleeve 206 from the inside of the driving box 201 to realize the rapid replacement of the electric motor 202, which improves the maintenance convenience of the equipment.
