Description

Technical Field

[0001] This utility model relates to the field of door opening machine technology, and in particular to a horizontal drive sliding door integrated machine. Background Technology

[0002] Sliding doors are widely used for entrances and exits in various places, mainly for factory gates, hospitals and residential courtyards.

[0003] Currently, all types of sliding doors use door openers based on the gear and rack transmission principle. For example... Figure 1 As shown, the racks are all installed above the output gears of the gate opener. When there is a level deviation in the rack installation or a height difference in the ground of the installation foundation, the gate opener is prone to running jams during the operation of the gate. This problem leads to frequent adjustments of control parameters, and the current surges when jamming occurs. Therefore, during the design phase of the control board, it is necessary to increase the parameter values ​​of some electronic components to prevent component burnout. This not only increases the cost of the control system but also directly affects the power output and torque performance of the motor. To meet the required output torque, the motor power rating must be increased, which in turn leads to a corresponding increase in motor procurement costs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a horizontal drive sliding door integrated machine, which aims to solve the technical problems mentioned in the background art.

[0005] A horizontally driven sliding door integrated machine includes a gearbox assembly, a motor, and a horizontal transmission device. The gearbox assembly includes a gearbox body and a transmission shaft assembly disposed within the gearbox body. The transmission shaft assembly includes a first output shaft and a worm gear. The first output shaft is disposed within the gearbox body and rotatably connected to the gearbox body. The worm gear is movably connected to the first output shaft. The motor is disposed on the gearbox body and has a worm gear that passes through the top end of the gearbox body and extends into the gearbox body, meshing with the worm gear. A clutch push rod and a first bevel gear are respectively disposed at opposite ends of the first output shaft. The first bevel gear protrudes from the gearbox body. The horizontal transmission device includes a second output shaft and a second bevel gear and an output gear disposed on the second output shaft. The second output shaft is disposed outside the gearbox body. The first bevel gear meshes with the second bevel gear, and the output gear meshes with the rack of the sliding door. The first output shaft is perpendicular to the second output shaft.

[0006] In normal operation, the motor drives the worm gear to rotate, which in turn drives the worm wheel on the first output shaft to rotate. The first output shaft drives the second bevel gear on the second output shaft through the first bevel gear, thereby driving the output gear on the second output shaft to move the sliding door. When there is a power outage, the first output shaft can be separated from the worm wheel by operating the clutch lever, thereby enabling the sliding door to be moved manually.

[0007] This invention utilizes the self-locking characteristic of worm gear meshing to prevent accidental door sliding during power outages or machine shutdowns, ensuring high safety. The clutch push rod at the end of the first output shaft provides a manual emergency function, allowing manual door operation even in the event of motor failure, enhancing reliability. Direction switching is achieved through bevel gear meshing, resulting in a compact and space-saving structure. Short-range power transmission reduces losses, ensuring smooth and low-noise operation. It also solves the problem of jamming during vertical transmission of gears and racks, reducing costs and improving work efficiency.

[0008] Furthermore, the gearbox body is provided with a receiving groove for accommodating the worm gear, and the first output shaft is provided with a plurality of first bearings, which are interference-fitted with the gearbox body.

[0009] Furthermore, the horizontal transmission device also includes a bracket, which is fixedly connected to the outer wall of the gearbox. The bracket is provided with a first through hole and two second through holes. The first through hole is arranged horizontally along the bracket, and the two second through holes are arranged opposite each other vertically along the bracket. The first bevel gear extends into the bracket through the first through hole and meshes with the second bevel gear. One end of the second output shaft passes through one of its second through holes and extends into the other second through hole, and is respectively interference-fitted to the two second through holes through several second bearings. The second bevel gear is located between the two second through holes, and the other end of the second output shaft is provided with the output gear.

[0010] Furthermore, the second output shaft is keyed to the second bevel gear and the output gear. The second output shaft is also provided with a first retaining ring, a second retaining ring and an oil seal. The first retaining ring is located at the top of the output gear, the oil seal is located at the bottom of the output gear, and the second retaining ring is located in the second through hole adjacent to the output gear.

[0011] Furthermore, a control board bracket is fixed on the gearbox body, and a control board is mounted on the control board bracket. The control board is electrically connected to the motor.

[0012] Furthermore, the gearbox body is also provided with a magnetic limiting part, which is adapted to the magnet of the sliding door.

[0013] Furthermore, the bracket is provided with an end cap, which is located between the two second through holes.

[0014] Furthermore, the horizontally driven sliding door integrated machine also includes a housing, which is fixedly connected to the gearbox. Attached Figure Description

[0024] like Figure 1 As shown, the door openers used in various sliding doors are all based on the gear and rack transmission principle. The rack is installed above the output gear of the door opener. When there is a horizontal deviation in the installation of the rack or a height difference in the ground of the installation foundation, the door opener is prone to running jams during the operation of driving the door.

[0025] Please see Figures 2 to 5 A horizontally driven sliding door integrated machine includes a gearbox assembly 1, a motor 2, a horizontal transmission device 3, and a housing 6.

[0026] Specifically, the gearbox assembly 1 includes a gearbox body 11 and a drive shaft assembly 12 disposed within the gearbox body 11. The gearbox body 11 has a receiving groove 111 for accommodating a worm gear 122. The drive shaft assembly 12 includes a first output shaft 121 and a worm gear 122. The first output shaft 121 is disposed within the gearbox body 11 and rotatably connected to the gearbox body 11. The worm gear 122 is detachably connected to the first output shaft 121. The first output shaft 121 is provided with multiple first bearings 1216, which are interference-fitted with the gearbox body 11. The worm (not shown) meshes with the worm gear 122. The gearbox 11 is connected to the first output shaft 121. At opposite ends, there are clutch push rods 1211 and first bevel gears 1212. The first bevel gears 1212 protrude from the gearbox body 11. The worm gear 122 is detachably connected to the first output shaft 121 to enable manual operation during power outages. The first bearing 1216 is interference-fitted to the gearbox body 11 to enhance rigidity and reduce operating vibration. The receiving groove 111 effectively protects the worm gear 122 and extends its service life. The clutch push rods 1211 and the first bevel gears 1212 are integrated at both ends, resulting in high functional integration, saving space and improving transmission efficiency. The overall structure is compact and highly stable.

[0027] It should be noted that the worm gear 122 has a clutch groove (not shown) at one end facing the first bevel gear 1212, and a sliding groove 1213 is provided on the first output shaft 121. The inner hole of the worm gear 122 is fitted onto the first output shaft 121. Through the compression spring 1215 fitted on the first output shaft 121, the compression spring 1215 compresses the clutch pin 1214 to cooperate with the clutch groove of the worm gear 122. The clutch pin 1214 can move in the sliding groove 1213 of the first output shaft 121. When the power is off, the clutch push rod 1211 provided in the inner hole of the first output shaft 121 is rotated by the clutch key, which pushes the clutch pin 1214 to disengage from the worm gear 122, so that the first output shaft 121 and the worm gear 122 are separated, thereby enabling the door to move.

[0028] Specifically, motor 2 is mounted on gearbox 11, and a worm gear is mounted on motor 2. The worm gear passes through the top of gearbox 11 and extends into the gearbox body, meshing with worm wheel 122. A control board bracket 4 is fixed on gearbox 11, and a control board 41 is mounted on the control board bracket 4. The control board 41 is electrically connected to motor 2. A magnetic limiting part 5 is also provided on gearbox 11, which is compatible with the magnet of the sliding door. The housing 6 is fixedly connected to gearbox 11. This solution uses motor 2 to drive the worm gear transmission mechanism, and the load is driven by the meshing transmission between the worm gear and worm wheel 122. The core relies on the self-locking characteristics of worm wheel 122 and worm gear, which can effectively prevent the door from accidentally sliding when the equipment is powered off or stopped, significantly improving the safety of use. The gearbox 11 also integrates an intelligent controller, which supports remote signal input and status feedback to realize the automated control of the sliding door. To ensure precise door positioning, a magnetic limiter 5 is specially configured—through precise adsorption with the built-in magnet of the sliding door, the door's position is locked more securely after movement. In addition, a protective housing 6 is added to the top of the gearbox 11, completely enclosing it to form a closed protective structure. This effectively prevents external rainwater, dust, and foreign objects from entering, providing a stable operating environment for the internal transmission components and extending the equipment's service life.

[0029] Specifically, the horizontal transmission device 3 includes a bracket 32, a second output shaft 31, and a second bevel gear 311 and an output gear 312 mounted on the second output shaft 31. The second output shaft 31 is located outside the reduction gearbox 11. The first bevel gear 1212 meshes with the second bevel gear 311, and the output gear 312 meshes with the rack of the sliding door. The first output shaft 121 is perpendicular to the second output shaft 31. The bracket 32 ​​is fixedly connected to the outer wall of the reduction gearbox 11. The bracket 32 ​​has a first through hole 321 and two second through holes 322. The first through hole 321 is arranged horizontally along the bracket 32, and the two second through holes 322 are arranged opposite each other vertically along the bracket 32. The first bevel gear 1212 extends into the bracket 32 ​​through the first through hole 321. The first output shaft 31 is located between the first bevel gear 311 and the second output shaft 322. One end of the second output shaft 31 passes through one second through hole 322 and extends into another second through hole 322. It is press-fitted to the two second through holes 322 by several second bearings 33. The second bevel gear 311 is located between the two second through holes 322. The other end of the second output shaft 31 is provided with an output gear 312. The bracket 32 ​​is provided with an end cap 37, which is located between the two second through holes 322. The bracket 32 ​​provides rigid support for the second output shaft 31. Through the layout design of the first through hole 321 and the two second through holes 322, the first output shaft 121 and the second output shaft 31, which are perpendicular to each other, are respectively installed, realizing the conversion of the transmission direction from horizontal to vertical. When the first output shaft 121 is running, the meshing transmission between the first bevel gear 1212 and the second bevel gear 311 drives the second output shaft 31 to rotate and drive the output gear 312. The second bearing 33 and the second through hole 322 are connected by an interference fit, which effectively improves the structural rigidity and reduces vibration during operation. The end cover 37 not only facilitates disassembly, replacement and maintenance, but also prevents the intrusion of external foreign objects during normal operation, avoiding interference with the normal operation of the system.

[0030] Specifically, the second output shaft 31 is keyed to the second bevel gear 311 and the output gear 312. The second output shaft 31 is also equipped with a first retaining ring 34, a second retaining ring 35, and an oil seal 36. The first retaining ring 34 is located at the top of the output gear 312, the oil seal 36 is located at the bottom of the output gear 312, and the second retaining ring 35 is located in the second through hole 322 adjacent to the output gear 312. This structure is compact and reasonable. The keyed connection ensures the reliability and alignment of power transmission between the second output shaft 31 and the second bevel gear 311 and the output gear 312. The first retaining ring 34 and the second retaining ring 35 form a double axial positioning, effectively limiting the movement of the output gear 312 and the second output shaft 31. The oil seal 36 prevents leakage of lubricating medium and intrusion of external impurities, improving transmission stability, sealing performance, and component durability in multiple dimensions, and extending the service life of the equipment.

[0031] In normal operation, the motor 2 drives the worm gear to rotate, which in turn drives the worm wheel 122 on the first output shaft 121 to rotate. The first output shaft 121 drives the second bevel gear 311 on the second output shaft 31 through the first bevel gear 1212, which in turn drives the output gear 312 on the second output shaft 31, thereby causing the output gear 312 to move the sliding door. When there is a power outage, the first output shaft 121 can be separated from the worm wheel 122 by operating the clutch push rod 1211, thereby enabling the sliding door to be moved manually.

[0032] This invention utilizes the self-locking characteristic of the worm gear 122 and worm shaft meshing to prevent accidental sliding of the door body during power outages or machine shutdowns, ensuring high safety. The clutch push rod 1211 at the end of the first output shaft 121 provides a manual emergency function, allowing manual drive of the door body even in the event of motor failure, enhancing reliability. Direction switching is achieved through bevel gear meshing, resulting in a compact structure that saves space. Short-range power transmission reduces losses, ensuring smooth and low-noise operation. It also solves the problem of jamming during vertical transmission of gears and racks, reducing costs and improving work efficiency.
