Description

Technical Field

[0001] This utility model relates to the field of drive equipment technology, and in particular to a speed reducer drive device for roller shutter doors. Background Technology

[0002] The key component of automatic roller shutter doors is the motor. In areas with underdeveloped power supply, non-fully electric motors are more common, while in areas with developed power supply, electric roller shutter doors are basically ubiquitous. If the power supply is intermittent, the current automatic / manual switching method for roller shutter doors is rather cumbersome, leading to imperfections in the continuous and stable operation of the doors. The basic components of an existing roller shutter door drive system consist of a gearbox assembly, a motor, a brake housing assembly, a manual chain, a manual lever, an electrical assembly, a push-button switch, and a limit switch assembly. The motor and gearbox assembly work together, with the motor driving the roller shutter door up and down at a specified speed and torque. The brake housing assembly, under power-on or power-off conditions, releases or locks the rotor shaft to ensure the roller shutter door is in a running or stopped state. Under power-off conditions, the manual lever releases the locked rotor shaft from the brake housing assembly, and then the manual chain rotates the rotor shaft to achieve the same up and down movement. The electrical assembly consists of components such as an integrated control board and is connected to the push-button switch. The limit switch assembly disengages from the sprocket during motor operation to ensure sprocket rotation; when the motor stops, it locks the sprocket to ensure the roller shutter door is stationary when the motor is stopped. The push-button switch controls the forward and reverse running time of the motor, and opens or closes the limit switch assembly and brake via the electrical assembly.

[0003] In the absence of power, the manual lever is used to open the brake housing assembly and lock the rotor shaft. Pulling the manual chain rotates the rotor shaft, enabling the roller shutter door to move up and down and be in operation. Each switch requires manual operation, and some even require climbing to manually operate it, making it extremely inconvenient to use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a speed reducer drive device for roller shutter doors.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

It also includes a clutch mounting frame, a drive shaft, a driven shaft, and a clutch cover. The drive shaft is connected to the output end of the speed reducer. A fixed gear is mounted on the side of the drive shaft away from the speed reducer. The clutch mounting frame is located on the side of the speed reducer. The driven shaft is mounted on the clutch mounting frame. An output turntable and a manual turntable are fixedly mounted on the driven shaft. A clutch drive disc is located on the side of the driven shaft closest to the drive shaft. The clutch drive disc is equipped with... A limiting slide rod is provided, and the clutch movable cover slides axially and is sleeved on the limiting slide rod. The inner side wall of the clutch movable cover is provided with a gear groove, which is engaged with a fixed gear. The driving shaft, driven shaft, clutch movable cover and fixed gear are all on the same axis. A separation spring is sleeved on the limiting slide rod. The separation spring pushes the clutch movable cover away from the driven shaft, so that the gear groove is separated from the fixed gear. A separation electromagnet is provided on the inner side of the clutch drive disc. When the separation electromagnet is activated, the clutch movable cover is attracted to the side close to the driven shaft, so that the fixed gear is embedded in the gear groove.

[0007] In some embodiments, the fixed gear is a bevel gear.

[0008] In some embodiments, four limiting slide rods are provided, and the four limiting slide rods are equally spaced and arranged circumferentially on the clutch drive disc, with a release spring sleeved on each limiting slide rod.

[0009] In some embodiments, a manual adjustment chain is also included, which is fitted onto a manual turntable.

[0010] In some embodiments, anti-fall-off baffles are provided on both sides of the manual turntable, and the inner sidewalls of the anti-fall-off baffles are inclined.

[0011] In some embodiments, the clutch mounting frame includes a protective baffle and support rods. Three support rods are provided, one end of each support rod is fixed to one side of the reducer, and the protective baffle is fixed to the other end of the three support rods. The drive shaft is rotatably mounted on the protective baffle on the side near the reducer.

[0012] In some embodiments, the protective baffle is provided with a bearing chamber, and a bearing is installed from one end of the power shaft and installed in the bearing chamber.

[0013] In some embodiments, the drive motor is provided with a brake, which is integral with the motor rear cover and fixed to the stator housing. The brake opening / closing and the drive motor running on / off are set to be consistent.

[0014] The advantages of this utility model are:

[0015] Firstly, this solution includes components such as a clutch mounting frame, a drive shaft, a driven shaft, and a clutch movable cover. The reducer is installed at the output end of the drive motor. The drive shaft is connected to the output end of the reducer, and a fixed gear is located on the side of the drive shaft away from the reducer. The clutch mounting frame is located on the side of the reducer. The driven shaft is rotatably mounted on the clutch mounting frame. An output turntable and a manual turntable are fixedly mounted on the driven shaft, and the output turntable is connected to the roller shutter door drive shaft. A clutch drive disc is located on the side of the driven shaft near the drive shaft, and a limit slide rod is provided on the clutch drive disc. The clutch movable cover slides axially and is fitted onto the limit slide rod. A gear groove is provided on the inner wall of the clutch movable cover, and the gear groove meshes with the fixed gear. The drive shaft, driven shaft, clutch movable cover, and fixed gear are all on the same axis. When the drive device is energized, the separation electromagnet is activated, which attracts the clutch movable cover close to the driven shaft. One side of the drive shaft has a fixed gear embedded in the gear slot. The user can control the drive motor to rotate forward and backward according to the operating requirements. The drive motor transmits power to the reducer, which in turn transmits power to the drive shaft. The drive shaft drives the fixed gear to rotate, which in turn drives the clutch cover to rotate. The clutch cover drives the driven shaft to rotate, which in turn drives the output turntable to rotate. The output turntable drives the roller shutter door drive shaft to rotate, thereby controlling the opening and closing of the roller shutter door. When the drive device is de-energized, the separation electromagnet stops operating. The separation spring pushes the clutch cover away from the driven shaft, separating the gear slot from the fixed gear. At this time, the user can manually adjust the chain by pulling it forward and backward. The manual adjustment of the chain drives the manual turntable to rotate, which in turn drives the driven shaft to rotate. The driven shaft drives the output turntable to rotate, which in turn drives the roller shutter door drive shaft to rotate, thereby controlling the opening and closing of the roller shutter door.

[0016] Secondly, this solution includes a brake on the drive motor, which is integrated with the motor's rear cover and fixed to the stator housing. The brake's opening / closing and the drive motor's start / stop settings are synchronized. This ensures the roller shutter door remains in a safe state at any stage during opening and closing.

[0017] Thirdly, the fixed gear in this solution is a bevel gear. The outer diameter of the fixed gear on the side closer to the driving shaft is smaller than the outer diameter on the side closer to the driven shaft. The gear groove inside the clutch movable cover fits with the outer contour of the fixed gear, which facilitates the clutch movable cover to fit with the fixed gear during the sliding process.

[0018] Fourthly, the clutch mounting frame in this solution includes a protective baffle and support rods. Three support rods are provided, with one end of each support rod fixed to one side of the reducer. The protective baffle is fixed to the other end of each support rod. The drive shaft is rotatably mounted on the protective baffle near the reducer. This allows the clutch mounting frame, drive motor, and reducer to form an integrated structure, facilitating the installation and adjustment of the drive device by the operator.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The following combination Figures 1-5 This application provides a detailed description of the technical solutions provided in each embodiment.

[0028] A speed reducer drive device for roller shutter doors includes a drive motor 1, a speed reducer 2, a clutch mounting frame 3, a drive shaft 4, a driven shaft 5, and a clutch movable cover 6. The speed reducer 2 is mounted on the output end of the drive motor 1. The drive shaft 4 is connected to the output end of the speed reducer 2. A fixed gear 41 is provided on the side of the drive shaft 4 away from the speed reducer 2. The clutch mounting frame 3 is located on the side end of the speed reducer 2. The driven shaft 5 is rotatably mounted on the clutch mounting frame 3. An output turntable 5 is fixedly mounted on the driven shaft 5. 1. A manual turntable 52 and an output turntable 51 are connected to the roller shutter door drive shaft. A clutch drive disc 53 is provided on the side of the driven shaft 5 near the main drive shaft 4. A limit slide rod 531 is provided on the clutch drive disc 53. The clutch movable cover 6 is axially slidably sleeved on the limit slide rod 531. A gear groove 61 is provided on the inner side wall of the clutch movable cover 6. The gear groove 61 is engaged with the fixed gear 41. The main drive shaft 4, the driven shaft 5, the clutch movable cover 6 and the fixed gear 41 are all on the same axis.

[0029] The limiting slide bar 531 is fitted with a separation spring 532. The separation spring 532 pushes the clutch movable cover 6 away from the driven shaft 5, causing the gear groove 61 to separate from the fixed gear 41. At this time, the user can manually rotate the manual turntable 52 to drive the driven shaft 5 to rotate. The driven shaft 5 drives the output turntable 51 to rotate, which in turn drives the roller shutter door drive shaft to rotate, thereby controlling the opening and closing of the roller shutter door.

[0030] The clutch drive disc 53 is equipped with a separation electromagnet on its inner side. When the separation electromagnet is activated, the clutch movable cover 6 is attracted to the side close to the driven shaft 5, so that the fixed gear 41 is embedded in the gear groove 61. At this time, the gear groove 61 and the fixed gear 41 are in transmission cooperation, and the roller shutter door can be controlled to open and close by driving the roller shutter door drive shaft to rotate through the drive motor 1.

[0031] In some embodiments, a brake 8 is provided on the drive motor 1. The brake 8 is directly fixed to the stator housing. The brake opening / closing and the drive motor 1 running on / off are set to be consistent. This achieves an effective switching between the state of the brake engaging and releasing the rotor shaft, and the structure is simple.

[0032] In some embodiments, the fixed gear 41 is a bevel gear, and the outer diameter of the fixed gear 41 on the side closer to the driving shaft 4 is smaller than the outer diameter on the side closer to the driven shaft 5. The gear groove 61 inside the clutch movable cover 6 matches the outer contour of the fixed gear 41, thereby facilitating the matching of the clutch movable cover 6 with the fixed gear 41 during the sliding process.

[0033] In some embodiments, four limiting slide rods 531 are provided, and the four limiting slide rods 531 are equally spaced around the clutch drive disc 53. Each limiting slide rod 531 is fitted with a release spring 532, thereby improving the stability of the clutch drive disc 53 during sliding adjustment.

[0034] In some embodiments, a manual adjustment chain 7 is also included, which is sleeved on the manual turntable 52. The user can control the rotation of the manual turntable 52 by pulling the manual adjustment chain 7, thereby enabling the user to control the rotation of the drive shaft 5 from a position far away from the drive device.

[0035] In some embodiments, anti-drop baffles are provided at both ends of the manual turntable 52. The inner sidewall of the anti-drop baffle is inclined. The anti-drop baffle can limit the manual adjustment chain 7, thereby ensuring that the manual adjustment chain 7 always cooperates with the manual turntable 52 when the user operates it.

[0036] In some embodiments, the clutch mounting frame 3 includes a protective baffle 31 and support rods 32. Three support rods 32 are provided. One end of the three support rods 32 is fixed to the reducer fixing foot, and the other end of the three support rods 32 is fixed to the clutch mounting frame 3. This allows the clutch mounting frame 3, the drive motor 1, and the reducer 2 to form an integrated structure, thereby facilitating the installation and adjustment of the drive device by the operator.

[0037] In some embodiments, the protective baffle 31 is provided with a bearing chamber, and a bearing 311 is installed at one end of the driven shaft 5 and the bearing is installed in the bearing chamber. This can improve the rotational stability and flexibility of the driven shaft 5.

[0038] When the drive unit is powered on, the separation electromagnet is activated, which attracts the clutch movable cover 6 to the side near the driven shaft 5, causing the fixed gear 41 to engage in the gear groove 61. The user can control the drive motor 1 to rotate in both directions according to the operating requirements. The drive motor 1 transmits power to the reducer 2, which in turn transmits power to the drive shaft 4. The drive shaft 4 drives the fixed gear 41 to rotate, which in turn drives the clutch movable cover 6 to rotate, which in turn drives the driven shaft 5 to rotate, which in turn drives the output turntable 51 to rotate, which in turn drives the roller shutter door drive shaft to rotate, thereby controlling the opening and closing of the roller shutter door.

[0039] When the drive unit is powered off, the separation electromagnet stops operating. The separation spring 532 pushes the clutch movable cover 6 away from the driven shaft 5, causing the gear groove 61 to separate from the fixed gear 41. At this time, the user can manually adjust the chain 7 by pulling it in both directions. The manual adjustment of the chain 7 drives the manual turntable 52 to rotate, which in turn drives the driven shaft 5 to rotate. The driven shaft 5 drives the output turntable 51 to rotate, which in turn drives the roller shutter door drive shaft to rotate, thereby controlling the opening and closing of the roller shutter door.
