Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic actuators, and in particular to an electronic actuator with a simplified gear transmission structure. Background Technology
[0002] An electric actuator is a mechanical device driven by electricity that converts control signals into mechanical motion, thereby enabling the control of equipment or systems.
[0003] When using an electronically controlled actuator with a simplified internal gear transmission structure in a car, the motor inside the electric control housing starts. The gear at the motor's output then drives the gear on the worm gear to rotate. The worm gear, in turn, drives the worm wheel, which in turn drives the output shaft to rotate, thus completing the electronic control. However, prolonged rotation of the actuator's output shaft causes significant wear against the housing, leading to problems that affect the actuator's performance. Utility Model Content
[0004] The technical problem this invention aims to solve is that when the output shaft of an electric actuator rotates for a long time, it experiences significant wear against the housing, which in turn affects the performance of the electric actuator.
[0005] The technical solution adopted by this utility model to solve its technical problem is: an electric actuator with a simplified gear transmission structure, including a housing and a mounting assembly. An output shaft is provided on one side of the housing, and a lubrication device is provided on one side of the housing by means of the mounting assembly. The lubrication device uses lubricating oil inside the storage tank to lubricate the connection between the output shaft and the housing.
[0006] The effect achieved by the above components is as follows: When using an electronically controlled actuator with a simplified internal gear transmission structure in a car, the lubrication device is fixed to one side of the housing by the mounting assembly. Then, the motor inside the housing is started by electric control. The gear on the output end of the motor drives the gear on the worm to rotate. After the worm is rotated, it drives the worm wheel to rotate. Finally, the worm wheel drives the output shaft to rotate. When the output shaft rotates, the connection between the output shaft and the housing can be lubricated by the lubrication device, and finally the electronic control is completed.
[0007] Preferably, the lubrication device includes a placement plate, an electric telescopic rod, a piston, a storage tank, a pipe, and a solenoid valve. The electric telescopic rod is disposed on the surface of the placement plate. The piston is disposed at the output end of the electric telescopic rod and inside the storage tank. The storage tank is disposed at the upper end of the placement plate. The pipe is disposed at the upper end of the storage tank, and its outlet is located at the connection between the outer casing and the output shaft. The solenoid valve is disposed on one side of the pipe to control the opening and closing of the pipe.
[0008] The effect achieved by the above components is as follows: When adding lubricating oil, the electric telescopic rod fixed on one side of the placement plate is activated, causing the piston at the output end of the electric telescopic rod to move inside the storage tank fixed on one side of the placement plate. Then, the piston pushes the lubricating oil inside the storage tank and activates the solenoid valve fixed on the pipeline, opening the pipeline. The lubricating oil then reaches the connection between the output shaft and the housing through the pipeline fixed on one side of the storage tank, thus lubricating the connection between the output shaft and the housing. By using the lubrication device, lubricating oil can be added at the connection between the output shaft and the housing, reducing the friction between the output shaft and the housing, thereby reducing wear on the output shaft and the housing, and thus improving the performance of the electric actuator.
[0009] Preferably, a reinforcing plate is provided for the connection between the placement plate and the storage tank, and the reinforcing plate increases the connection strength between the placement plate and the storage tank.
[0010] The effect achieved by the above components is that by fixing the reinforcing plate to the placement plate and the storage tank, the connection strength between the storage tank pipe and the placement plate is improved, thus preventing deformation at the connection point.
[0011] Preferably, the piston is provided with an auxiliary block on the side away from the electric telescopic rod, and the auxiliary block allows the lubricating oil to reach the pipeline better.
[0012] The effect achieved by the above components is that by fixing an auxiliary block on one side of the piston, and the auxiliary block being elastic, and then the inclined surface of the auxiliary block being close to the side of the storage tank fixing pipe, the last part of the lubricating oil in the storage tank will be better squeezed into the pipe.
[0013] Preferably, the mounting assembly includes a mounting block, bolts, and a connecting plate. The mounting block is disposed on one side of the housing, and the bolts are inserted inside the mounting block to fix the connecting plate inside the mounting block. The connecting plate is disposed on one side of the placement plate.
[0014] The effect achieved by the above components is as follows: When fixing the lubrication device, move the placement plate so that the connecting plate on one side of the placement plate reaches the inside of the mounting block. At this time, the pipe outlet reaches the connection between the housing and the output shaft. Then, rotate the bolt so that the bolt passes through the mounting block and the connecting plate for threaded fixing. Then the position of the placement plate is fixed. By using the installation components, the lubrication device can be quickly installed and fixed on the surface of the housing, which makes it convenient for operators to use the lubrication device in the future.
[0015] Preferably, a washer is provided on the side of the bolt near the mounting block, and the washer increases the contact area between the bolt and the mounting block.
[0016] The effect achieved by the above components is that by abutting the fixing washer on one side of the bolt, the contact area between the bolt and the mounting block is increased, so that the bolt can better fix the connecting plate.
[0017] Preferably, an operating block is provided on one side of the bolt, and the operating block increases the dimension of one side of the bolt.
[0018] The effect achieved by the above components is to increase the contact area between the operator and the bolt by fixing the operating block on one side of the bolt, making it easier for the operator to turn the bolt.
[0019] Preferably, a guide plate is provided on one side of the mounting block, and the guide plate is inclinedly disposed on one side of the mounting block.
[0020] The effect achieved by the above components is that by fixing the guide plate on one side of the mounting block, the guide plate raises the size of the entrance of the mounting block, making it easier for the connecting plate to reach the inside of the mounting block.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] By using a lubrication device, lubricating oil can be added at the connection between the output shaft and the housing, reducing the friction between the output shaft and the housing, thereby reducing wear on the output shaft and the housing, and thus improving the performance of the electric actuator.
[0023] By using the mounting components, the lubrication device can be quickly installed and fixed to the housing surface, making it convenient for operators to use the lubrication device subsequently. Attached Figure Description

[0032] Figures 1 to 4 The illustrated electrically controlled actuator with a simplified gear transmission structure includes a housing 1 and a mounting assembly 4. An output shaft 2 is located on one side of the housing 1, and a lubrication device 3 is also located on the same side via the mounting assembly 4. The lubrication device 3 uses lubricating oil stored in a reservoir 34 to lubricate the connection between the output shaft 2 and the housing 1. When using this electrically controlled actuator with a simplified internal gear transmission structure in an automobile, the lubrication device 3 is fixed to one side of the housing 1 via the mounting assembly 4. Then, the motor inside the housing 1 is started electrically. The gear on the motor's output end drives the gear on the worm gear to rotate. The worm gear, being rotated, drives the worm wheel to rotate, and finally, the worm wheel drives the output shaft 2 to rotate. During the rotation of the output shaft 2, the connection between the output shaft 2 and the housing 1 is lubricated using the lubrication device 3, thus completing the electrical control.
[0033] Figures 1 to 4The lubrication device 3 shown includes a placement plate 31, an electric telescopic rod 32, a piston 33, a storage tank 34, a pipe 35, and a solenoid valve 36. The electric telescopic rod 32 is disposed on the surface of the placement plate 31. The piston 33 is disposed at the output end of the electric telescopic rod 32 and is located inside the storage tank 34. The storage tank 34 is disposed on the upper end of the placement plate 31. The pipe 35 is disposed on the upper end of the storage tank 34, and its outlet is located at the connection between the outer casing 1 and the output shaft 2. The solenoid valve 36 is disposed on one side of the pipe 35 to control the opening and closing of the pipe 35. When adding lubricating oil, the electric telescopic rod 32 fixed on one side of the placement plate 31 is activated, causing the piston 33 at the output end of the electric telescopic rod 32 to move inside the storage tank 34 fixed on one side of the placement plate 31. Then, the piston 33 pushes the lubricating oil inside the storage tank 34 and activates the solenoid valve 36 fixed on the pipeline 35, opening the pipeline 35. Then, the lubricating oil reaches the connection between the output shaft 2 and the housing 1 through the pipeline 35 fixed on one side of the storage tank 34, thus lubricating the connection between the output shaft 2 and the housing 1. By using the lubrication device 3, lubricating oil can be added to the connection between the output shaft 2 and the housing 1, reducing the friction between the output shaft 2 and the housing 1, thereby reducing the wear of the output shaft 2 and the housing 1 and improving the performance of the electric actuator.
[0034] Figures 1 to 4 A reinforcing plate 37 is provided connecting the placement plate 31 and the storage tank 34, thereby increasing the connection strength between them. By fixing the reinforcing plate 37 to both the placement plate 31 and the storage tank 34, the connection strength between the storage tank pipe and the placement plate 31 is increased, preventing deformation at the connection point. An auxiliary block 38 is provided on the side of the piston 33 away from the electric telescopic rod 32, allowing lubricating oil to reach the pipe 35 more effectively. By fixing the auxiliary block 38 to one side of the piston 33, and ensuring the auxiliary block 38 is elastic, with its inclined surface close to the side of the storage tank 34 that fixes the pipe 35, the last portion of lubricating oil from the storage tank 34 is better squeezed into the pipe 35.
[0035] Figures 1 to 4 The mounting assembly 4 shown includes a mounting block 41, bolts 42, and a connecting plate 43. The mounting block 41 is located on one side of the housing 1, and the bolts 42 are inserted into the mounting block 41 to fix the connecting plate 43 inside the mounting block 41. The connecting plate 43 is located on one side of the placement plate 31. When fixing the lubrication device 3, the placement plate 31 is moved so that the connecting plate 43 on one side of the placement plate 31 reaches the interior of the mounting block 41. At this time, the outlet of the pipe 35 reaches the connection between the housing 1 and the output shaft 2. Then, the bolts 42 are rotated so that the bolts 42 pass through the mounting block 41 and are threadedly fixed to the connecting plate 43. Then, the position of the placement plate 31 is fixed. By using the mounting assembly 4, the lubrication device 3 can be quickly installed and fixed to the surface of the housing 1, which facilitates the subsequent use of the lubrication device 3 by the operator.
[0036] Figures 1 to 4 A washer 44 is provided on the side of the bolt 42 near the mounting block 41, increasing the contact area between the bolt 42 and the mounting block 41. By fixing the washer 44 against one side of the bolt 42, the contact area between the bolt 42 and the mounting block 41 is increased, allowing the bolt 42 to better secure the connecting plate 43. An operating block 45 is provided on one side of the bolt 42, increasing the dimension of one side of the bolt 42. By fixing the operating block 45 to one side of the bolt 42, the contact area between the operator and the bolt 42 is increased, making it easier for the operator to rotate the bolt 42. A guide plate 46 is provided on one side of the mounting block 41, inclined on one side of the mounting block 41. By fixing the guide plate 46 to one side of the mounting block 41, the guide plate 46 increases the dimension of the entrance of the mounting block 41, making it easier for the connecting plate 43 to reach the interior of the mounting block 41.
[0037] Working principle: When using an electronically controlled actuator with a simplified internal gear transmission structure in a car, the lubrication device 3 is fixed to one side of the housing 1 by the mounting component 4. Then, the motor inside the housing 1 is started by electric control. The gear on the output end of the motor drives the gear on the worm to rotate. After the worm is rotated, it drives the worm wheel to rotate. Finally, the worm wheel drives the output shaft 2 to rotate. When the output shaft 2 rotates, the connection between the output shaft 2 and the housing 1 can be lubricated by the lubrication device 3, and finally the electronic control is completed. When adding lubricating oil, the electric telescopic rod 32 fixed on one side of the placement plate 31 is activated, causing the piston 33 at the output end of the electric telescopic rod 32 to move inside the storage tank 34 fixed on one side of the placement plate 31. Then, the piston 33 pushes the lubricating oil inside the storage tank 34 and activates the solenoid valve 36 fixed on the pipeline 35, opening the pipeline 35. Then, the lubricating oil reaches the connection between the output shaft 2 and the housing 1 through the pipeline 35 fixed on one side of the storage tank 34, thus lubricating the connection between the output shaft 2 and the housing 1. By using the lubrication device 3, lubricating oil can be added to the connection between the output shaft 2 and the housing 1, reducing the friction between the output shaft 2 and the housing 1, thereby reducing the wear of the output shaft 2 and the housing 1 and improving the performance of the electric actuator.
[0038] When fixing the lubrication device 3, move the placement plate 31 so that the connecting plate 43 on one side of the placement plate 31 reaches the inside of the mounting block 41 with the guide plate 46. At this time, the outlet of the pipe 35 reaches the connection between the housing 1 and the output shaft 2. Then, by operating the block 45, rotate the bolt 42 so that the bolt 42 passes through the washer 44 and the mounting block 41 and is threadedly fixed to the connecting plate 43. Then the position of the placement plate 31 is fixed. By using the mounting assembly 4, the lubrication device 3 can be quickly installed and fixed to the surface of the housing 1, which makes it convenient for the operator to use the lubrication device 3 in the future.
