Description

Technical Field

[0001] This utility model relates to the field of synchronous electric linear actuator technology, specifically a synchronous electric linear actuator. Background Technology

[0002] Synchronous electric linear actuators are electrically driven devices that convert the rotary motion of an electric motor into the linear reciprocating motion of a linear actuator, ensuring the synchronous operation of multiple linear actuators. A typical synchronous electric linear actuator consists of a drive motor, reduction gears, a screw, a nut, a guide sleeve, and the linear actuator itself. After being reduced in speed by gears or a worm gear, the motor drives the screw and nut pair to convert the motor's rotary motion into linear motion. The forward and reverse rotation of the motor completes the extension and retraction of the linear actuator. Synchronous electric linear actuators are also equipped with a synchronization control system, which uses controllers, sensors, and other components to monitor and adjust the motion state of each linear actuator to ensure they remain synchronized during operation.

[0003] Existing synchronous electric linear actuators suffer from inconsistent synchronization accuracy due to wear differences in internal transmission components and uneven load during use. This can lead to problems such as shaking or object tipping during pushing. Current adjustment methods rely on manual adjustment, which is too simplistic and can only adjust deviations that are visually observable. Therefore, we propose a new synchronous electric linear actuator. Utility Model Content

[0004] The purpose of this invention is to provide a synchronous electric linear actuator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a synchronous electric push rod, comprising a synchronous electric push rod, wherein two sets of compensation components are symmetrically installed on the left end of the synchronous electric push rod. The main function of the compensation components is to prevent synchronous transport deviation caused by the influence of objects when the synchronous electric push rod moves. The compensation components include a baffle sleeved on the outer wall of the right end of the push rod, a second cylindrical ring fixed to the right end of the baffle, a telescopic component installed inside the second cylindrical ring, a first cylindrical ring fixed to the right end of the baffle, the first cylindrical ring sleeved on the outer wall of the second cylindrical ring, and a transmission component for realizing the displacement of the telescopic component installed outside the first cylindrical ring.

[0006] Furthermore, the transmission assembly includes four sets of telescopic rods equidistantly fixed to the left end of the outer wall of the first cylindrical ring. The left outer wall of the first cylindrical ring is provided with four sets of first through slots equidistantly. The output ends of the four sets of telescopic rods are all fixedly connected to second fixing rings. The bottom of the second fixing ring is located at the first through slot and a push block is fixedly connected to it. The right end of the push block is fixedly connected to a push rod. The left outer wall of the baffle is fixed with a first fixing ring. The first fixing ring is sleeved on the outer wall of the push rod. A laser rangefinder sensor is fixed to the front side of the first fixing ring.

[0007] Furthermore, the telescopic component includes four sets of second through slots equidistantly formed on the outer right side of the second cylindrical ring. A slider is slidably connected to the inner wall of the four sets of second through slots. The left end of the slider is fixedly connected to a push rod, and the right end of the slider is fixedly connected to a connecting rod. The right end of the connecting rod is fixedly connected to a second panel, and the second panel is slidably disposed on the inner wall of the second cylindrical ring.

[0008] Furthermore, a rectangular groove is provided at the right end of the inner wall of the second through groove, a spring is fixed to the inner wall of the rectangular groove, a contact block is fixed to the left end of the spring, the contact block is adapted to the rectangular groove, and a buffer block is fixed to the right end of the slider.

[0009] Furthermore, the buffer block is adapted to the contact block, and the buffer block is adapted to the rectangular groove.

[0010] Furthermore, the push block is adapted to the first through groove, and the right end outer wall of the first cylindrical ring is fixed with a first panel.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up synchronous electric push rods, compensation components, etc., during use, when the synchronous electric push rods are working normally, the laser rangefinder sensor will be activated. When it detects a difference in the accuracy of the two synchronous push rods, it will transmit a signal to the telescopic rod. The telescopic rod drives the second fixed ring to move to the right. At this time, the push block pushes the slider to slide to the right and causes the second panel to extend from the inside of the second cylindrical ring to compensate for this deviation, thereby making the object stable when moving. Through the above design, it is possible to compensate for the gap when the synchronization accuracy is different, thus ensuring the stability of the object. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 A synchronous electric linear actuator, comprising a synchronous electric linear actuator 1;

[0020] Before use, install the synchronous electric linear actuator 1, ensuring it is in a horizontal position. It should be noted that the synchronous electric linear actuator 1 typically consists of a drive motor, reduction gears, a screw, a nut, a guide sleeve, and a push rod. After the motor is reduced in speed by gears or a worm gear, it drives the screw and nut pair to convert the motor's rotational motion into linear motion. The extension and retraction of the push rod are completed by the forward and reverse rotation of the motor. For synchronous electric linear actuators, a synchronous control system is also provided, which monitors and adjusts the motion state of each push rod through controllers, sensors, and other components to ensure that they remain synchronized during operation. However, the above is considered existing technology and will not be elaborated further here.

[0021] In this embodiment, the compensation component 2 includes a baffle 21 sleeved on the outer wall of the right end of the push rod. A second cylindrical ring 17 is fixed to the right end of the baffle 21. A telescopic component is installed inside the second cylindrical ring 17. A first cylindrical ring 7 is fixed to the right end of the baffle 21. The first cylindrical ring 7 is sleeved on the outer wall of the second cylindrical ring 17. A transmission component that realizes the displacement of the telescopic component is installed outside the first cylindrical ring 7.

[0022] The main function of the compensation component 2 is that when the synchronous electric push rod 1 pushes the object, the laser rangefinder 4 will start to work. There are two sets of laser rangefinder 4, which work together. When the laser rangefinder 4 detects that the synchronization accuracy is consistent, the synchronous electric push rod 1 will work normally. During this time, the compensation component 2 will not work. At this time, the first panel 11 is in contact with the object, and the compensation component 2 will not be affected or in contact with the object.

[0023] When the laser rangefinder 4 detects a difference in synchronization accuracy, it transmits a signal to the telescopic rod 5. The telescopic rod 5 works synchronously at the same time as the synchronous electric push rod 1 is started. It should be noted that the telescopic rod 5 is started by the cooperation of the telescopic component and the transmission component, so that the second panel 14 inside the second cylindrical ring 17 protrudes and contacts the object first, thereby compensating for the deviation and achieving the stability of the object during transportation.

[0024] In the above, the transmission assembly includes four sets of telescopic rods 5 equidistantly fixed to the left end of the outer wall of the first cylindrical ring 7. Four sets of first through slots 8 are equidistantly opened on the left outer wall of the first cylindrical ring 7. The output ends of the four sets of telescopic rods 5 are all fixedly connected to second fixing rings 6. A push block 9 is fixedly connected to the bottom of the second fixing ring 6 at the first through slot 8. A push rod 10 is fixedly connected to the right end of the push block 9. A first fixing ring 3 is fixed to the left outer wall of the baffle 21. The first fixing ring 3 is sleeved on the outer wall of the push rod. A laser rangefinder sensor 4 is fixed to the front side of the first fixing ring 3. The telescopic assembly includes four sets of second through slots 15 equidistantly opened on the right outer wall of the second cylindrical ring 17. The inner walls of the four sets of second through slots 15 are slidably connected. There is a slider 12, the left end of which is fixedly connected to the push rod 10, the right end of which is fixedly connected to the connecting rod 13, and the right end of the connecting rod 13 is fixedly connected to the second panel 14. The second panel 14 is slidably disposed on the inner wall of the second cylindrical ring 17. A rectangular groove 16 is opened at the right end of the inner wall of the second through groove 15. A spring 20 is fixed on the inner wall of the rectangular groove 16. A contact block 19 is fixed at the left end of the spring 20. The contact block 19 is adapted to the rectangular groove 16. A buffer block 18 is fixed at the right end of the slider 12. The buffer block 18 is adapted to the contact block 19 and the rectangular groove 16. The push block 9 is adapted to the first through groove 8. The right outer wall of the first cylindrical ring 7 is fixed with the first panel 11.

[0025] Specifically, after the telescopic rod 5 is activated, it will push the second fixed ring 6 to move to the right. Four sets of push blocks 9 are set at the bottom of the second fixed ring 6. At the same time, the right side of the push block 9 is connected to the slider 12 through the push rod 10. It should be noted that the push block 9 slides on the outer wall of the second cylindrical ring 17, but does not contact the second cylindrical ring 17. Meanwhile, the outer wall of the second cylindrical ring 17 is fitted with the first cylindrical ring 7, and there is a space between the two. When the slider 12 slides inside the second through groove 15, the second panel 14 will slide out from the right inner wall of the second cylindrical ring 17 and contact the object, so that the laser range sensor 4 returns to the normal value. When the synchronous electric push rod 1 returns to the synchronized value, the second panel 14 will exceed a certain distance, so that the laser range sensor 4 will generate a data difference again. At this time, the telescopic rod 5 will be activated, and the second panel 14 will retract, so that the synchronous electric push rod 1 enters normal operation. This process is repeated to make up for the lack of synchronization accuracy and protect the stability of the object during movement.

[0026] Finally, a rectangular groove 16 is provided on the inner right side of the second through groove 15, and a spring 20 and a contact block 19 are provided inside it. Its main purpose is to provide a certain buffering effect when the buffer block 18 and the contact block 19 come into contact, so as to protect the stability of the component.

[0027] Working principle: After the telescopic rod 5 is activated, it pushes the second fixed ring 6 to move to the right. Four sets of push blocks 9 are set at the bottom of the second fixed ring 6. At the same time, the right side of the push block 9 is connected to the slider 12 through the push rod 10. It should be noted that the push block 9 slides on the outer wall of the second cylindrical ring 17, but does not contact the second cylindrical ring 17. Meanwhile, the outer wall of the second cylindrical ring 17 is fitted with the first cylindrical ring 7, and there is a space between the two. When the slider 12 slides inside the second through groove 15, the second panel 14 will slide out from the right inner wall of the second cylindrical ring 17 and contact the object, so that the laser range sensor 4 returns to the normal value. When the synchronous electric push rod 1 returns to the synchronized value, the second panel 14 will exceed a certain distance, so that the laser range sensor 4 will generate a data difference again. At this time, the telescopic rod 5 will be activated, and the second panel 14 will retract, so that the synchronous electric push rod 1 enters normal operation. This process is repeated to compensate for the lack of synchronization accuracy and protect the stability of the object during movement.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
