Description

Technical Field

[0001] This invention relates to the field of plastic recycling and processing technology, specifically to a plastic parts processing device for automotive interiors. Background Technology

[0002] Plastic recycling is of great significance in the manufacture of automotive plastic parts and is a core measure to promote the sustainable development of the industry. Every year, the scrapped cars generate a massive amount of waste plastic globally. If left to landfill or incinerate, it will waste resources and pollute the environment. By recycling and reusing plastics, the use of virgin plastics can be significantly reduced, and dependence on non-renewable resources such as petroleum can be decreased. The use of recycled plastics in automotive plastic parts is building a new industrial ecosystem that is resource-saving and environmentally friendly.

[0003] As a large interior component, the plastic center console frame typically ranges in length from 1 to 1.2 meters and employs a thin-walled structure (wall thickness 2.5 to 3.5 mm) to achieve lightweighting. During demolding and handling after injection molding, it requires lifting and moving using clamps. Furthermore, the center console frame has a complex geometry (such as multi-curved surfaces and partial mounting pillar structures), and is made of ABS or PC / ABS modified plastic, which features high rigidity and a low coefficient of thermal expansion to meet the dimensional stability requirements of the instrument panel mounting position.

[0004] The plastic control frame after injection molding and demolding may have residual stress inside, and the wall thickness is relatively thin and the dimensions are relatively long. Therefore, a tighter clamping method is usually not used when clamping to avoid excessive force or local stress concentration, which can easily cause structural deformation or surface indentation problems.

[0005] However, while using flexible suction cups to hold the demolded plastic center console frame can reduce surface damage and deformation caused by excessive clamping force, subsequent processing is problematic. Because the center console frame moves non-linearly during transport, the flexible clamping may cause it to twist and deform due to inertia during irregular or varying speed movements. For example, thin-walled areas of the plastic center console frame (such as around the instrument panel mounting position) may warp due to inertial forces. Since this area requires high precision, if this problem is not addressed promptly, it will affect the rework and adjustment rate during subsequent assembly of the plastic center console frame. Summary of the Invention

[0006] The purpose of this invention is to provide a plastic parts processing apparatus for automotive interiors to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a plastic parts processing apparatus for automotive interiors, which solves the above problems.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: a plastic parts processing device for automotive interiors, comprising a conveyor, a drive assembly fixedly connected to the outer wall of the conveyor, a sliding rail provided at the bottom of the conveyor, a slider and a sliding plate slidably connected to the inner wall of the sliding rail, the bottom of the sliding plate and the top of the slider being fixedly connected, and a clamping mechanism provided at the bottom of the slider;

There are two pull ropes, and one end of each of the two pull ropes is fixedly connected to the top of the two arc-shaped moving plates respectively.

[0015] Preferably, a hollow telescopic rod is fixedly connected to the center of the top of the connecting block, and the top of the hollow telescopic rod is hinged to the bottom of the fixed plate by a hinge ball. There are two lifting airbags, and a transverse airbag is fixedly connected to the side of the two lifting airbags that are close to each other. The elasticity of the transverse airbag is greater than that of the lifting airbag. The inner wall of the hollow telescopic rod is provided with air holes.

[0016] Preferably, an adjustment mechanism is provided on the inner wall of the top of the arc-shaped movable plate. The adjustment mechanism includes an arc-shaped telescopic plate. A connecting block is fixedly connected to one end of the arc-shaped telescopic plate away from the arc-shaped movable plate. The top of the connecting block is fixedly connected to the inner wall of the arc-shaped sleeve. The other end of the arc-shaped telescopic plate is fixedly connected to the top of the arc-shaped movable plate. A second spring is provided on the inner wall of the arc-shaped telescopic plate.

[0017] Preferably, the top of the arc-shaped sleeve has a connecting hole, the inner wall of the connecting block has a sealing cavity, the inner wall of the sealing cavity is slidably connected to a sliding column, and the inner wall of the sealing cavity communicates with the inner wall of the connecting hole through the interior of the connecting block.

[0018] Preferably, a push plate is fixedly connected to the end of the sliding column away from the connecting block. The push plate has a circular disc-shaped structure. A distance sensing processor is fixedly connected to one side of the connecting block. The distance sensing processor has a circular sleeve-shaped structure, and one side of the distance sensing processor is fixedly connected to the outer wall of the connecting block.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention, through the setting of a clamping mechanism and a multi-point lifting airbag conformal lifting design, not only disperses stress but also reduces local stress concentration through uniform force distribution. Furthermore, the flexible buffering effect of the lifting airbag material effectively absorbs vibrations during transportation, further reducing the probability of deformation. Compared with traditional suction cup clamping, this lifting airbag lifting avoids local stress concentration caused by point contact in suction cup clamping through a larger and more conformal contact area and uniform force distribution, reducing bending and warping problems caused by inertia.

[0021] 2. This invention, through the design of a clamping mechanism and a magnetic ball and an electromagnetic base, allows the magnetic ball to be electromagnetically attracted to the inner wall of the electromagnetic base. The ball bearings embedded in the inner wall of the electromagnetic base enable the magnetic ball to rotate freely within the base. Meanwhile, the fixed plate and the first spring connected below the magnetic ball pull the connecting block, the arc-shaped sleeve, and the arc-shaped moving plate, causing the plastic central control frame to rotate synchronously with the curve. This effectively balances the lateral inertial force, avoids sudden changes in internal stress, ensures the stability of the plastic central control frame during turning, and reduces the risk of deformation.

[0022] 3. By setting up a clamping mechanism, compared with the traditional suction cup type flexible clamping, this invention maximizes the multi-point large-area wrapping vertical support and rotates together with the turning process, so that all the horizontal forces on the plastic central control frame are uniformly transformed into vertical forces, maximizing the use of the clamping method of the lifting airbag, thereby avoiding the problem of horizontal internal stress generated inside the plastic central control frame.

[0023] 4. By setting up a clamping mechanism, when encountering a sudden turn during transmission, the instantaneous pressure generated between the lifting airbag and the plastic central control frame is released to a certain extent by stretching the first spring, allowing the plastic central control frame and the lifting airbag to move downward synchronously. This transforms the instantaneous force into a force that gradually increases over a period of time, thereby effectively mitigating the instantaneous impact and avoiding deformation caused by instantaneous high pressure.

[0024] 5. This invention, by setting an adjustment mechanism, accelerates the production of batches of plastic central control frames in factories where higher efficiency is needed. When a faster transmission speed is adopted, each arc-shaped moving plate slides away from each other to a certain extent, and overcomes part of the elastic force of the second spring in the inner wall of the arc-shaped telescopic plate. At the same time, the lifting airbag and the arc-shaped moving plate change from lifting deformation to lifting and lateral compression by the airbag, achieving dynamic balance between lifting and lateral support, ensuring that the plastic central control frame does not sway left and right when turning at high speed.

[0025] 6. This invention, by setting an adjustment mechanism, allows for the instantaneous increase in pressure between the lifting airbag and the plastic central control frame at high transmission speeds. The more elastic lateral airbag is then pushed out by the high pressure within the lifting airbag, wrapping around both sides of the plastic central control frame to prevent it from shifting during high-speed movement. This is specifically designed to address the additional pressure and swaying issues arising from increased speed between the plastic central control frame and the lifting airbag during high-speed movement, ensuring the plastic central control frame remains stable during high-speed movement and reducing the risk of deformation due to increased speed.

[0026] 7. By setting an adjustment mechanism, this invention not only achieves a better targeted clamping effect by changing the clamping position of the arc-shaped moving plate and the lifting airbag when they move, but also increases the multi-sided coverage force of the lifting airbag on the plastic central control frame as the inertia increases at high speeds when encountering curves. By absorbing some of the risk of slight deformation at the clamping point, it avoids the problem of greater deformation risk caused by the extremely unstable shaking of the plastic central control frame at high speeds. The advantages far outweigh the disadvantages. Thus, this adaptive dynamic adjustment is used to address the stability requirements of the easily deformable plastic central control frame in more high-speed movement scenarios, ensuring its reliable operation under complex working conditions.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figures 1-4 The present invention provides a technical solution: a plastic parts processing device for automotive interiors, including a conveyor 1, a drive assembly 5 fixedly connected to the outer wall of the conveyor 1, a sliding rail 6 provided at the bottom of the conveyor 1, a slider 9 and a sliding plate 10 slidably connected to the inner wall of the sliding rail 6, the bottom of the sliding plate 10 and the top of the slider 9 fixedly connected, and a clamping mechanism 3 provided at the bottom of the slider 9.

[0041] Clamping mechanism 3 includes:

[0042] Electromagnetic base 301 is fixedly connected to the bottom of slider 9. An arc-shaped sleeve 306 and an arc-shaped moving plate 307 are provided below the electromagnetic base 301. A pull rope retractor 312 is fixedly connected to the highest point of the inner wall of the arc-shaped sleeve 306.

[0043] A pull rope 313 is fixedly connected to the inner wall of the pull rope retractor 312. A lifting airbag 308 is fixedly connected to the surface of the arc-shaped moving plate 307. A plastic central control frame 8 is placed on the top of the lifting airbag 308.

[0044] In use, after a large amount of plastic is recycled, the recycled plastic is processed into powder granules and injection molded. After the mold separates, the injection-molded plastic central control frame 8 needs to be demolded and removed. An automated robotic arm positions and grips the plastic central control frame 8, pushing it into the arc-shaped sleeve 306 and the arc-shaped moving plate 307. The pull rope retractor 312 is activated, pulling the pull rope 313 back into the pull rope retractor 312, simultaneously pulling the arc-shaped moving plate 307 to slide along the inner wall of the arc-shaped sleeve 306. The pull rope 313 lifts the two arc-shaped moving plates 307 inside the arc-shaped sleeve 306, exposing the opening between the two arc-shaped moving plates 307. The robotic arm then grips and pushes the plastic central control frame 8 into the arc-shaped sleeve 306. Finally, the pull rope retractor 312 is controlled to lower the pull rope 313, and the arc-shaped moving plate 307 automatically resets and closes. The plastic central control frame 8 is securely fixed inside the arc-shaped sleeve 306, completing precise assembly. At the same time, the plastic central control frame 8 falls onto the air-filled support airbag 308 under gravity. The air inside the support airbag 308 and its deformable material make it completely fit the perforations of the plastic central control frame 8 (instrument panel mounting position and surrounding symmetrical holes), supporting the plastic central control frame 8. Then, by activating the drive component 5, the slider 9 begins to slide and transport along the inner wall of the sliding track 6. The slider 9 moves the arc-shaped sleeve 306 and the plastic central control frame 8 together to the designated position. Through the supporting and buffering effect of the support airbag 308, the high temperature of the plastic central control frame 8 when it is just demolded during transportation due to the clamping of rigid clamping parts is effectively avoided. The resulting thermal stress and mechanical stress are superimposed, which further aggravates the risk of deformation.

[0045] The multi-point lifting airbag 308's close-fitting lifting design not only disperses stress but also reduces local stress concentration through uniform force distribution. Furthermore, the flexible cushioning effect of the lifting airbag 308 material effectively absorbs vibrations during transportation, further reducing the probability of deformation. Compared to traditional suction cup clamping, the lifting airbag 308's lifting design avoids local stress concentration caused by point contact in suction cup clamping through a larger and closer contact area and uniform force distribution, reducing bending and warping problems caused by inertia.

[0046] Furthermore, when the transmission speed of the plastic central control frame 8 changes slightly, such as when accelerating to start transmission or decelerating to stop, the wall thickness of the plastic central control frame 8 is relatively thin. If it is clamped in a traditional way, the unclamped position will easily undergo stress change and torsion deformation due to inertia during acceleration and deceleration. However, the two arc-shaped moving plates 307 and the lifting airbag 308 are combined to form an arc shape, which allows the plastic central control frame 8 to have a certain range of swing on the lifting airbag 308. Therefore, when the vertical surface is subjected to inertial force, the problem of deformation of the unclamped position caused by inertia can be alleviated by slight swaying. However, if the plastic central control frame 8 is clamped in all directions, it will result in an overly complex clamping structure, and it will be difficult to adapt to different types of automotive plastic central control frames 8, making its application too limited.

[0047] Example 2: Please refer to Figures 1-8 Based on Embodiment 1, the present invention provides a technical solution: the transmission machine 1 is fixedly connected to both sides of the support 7, the support 7 is fixedly connected to one side of the protective bar 2, the electromagnetic base 301 is slidably connected to the bottom of the magnetic ball 302, the magnetic ball 302 is fixedly connected to the bottom of the fixed plate 303, the inner wall of the arc-shaped sleeve 306 is slidably connected to the outer wall of the arc-shaped moving plate 307, the inner wall of the lifting airbag 308 is fixedly connected to the arc-shaped moving plate 307, the air injector 310 is fixedly connected to the inner wall of the lifting airbag 308, the air injector 310 is fixedly connected to the top of the air injector 310, and the air injector 310 is used to inject air into the lifting airbag 308.

[0048] One end of the pull cord 313 away from the pull cord retractor 312 is fixedly connected to one end of the arc-shaped moving plate 307 via a connector 316. Open sleeves 314 are fixedly connected to both sides of the pull cord retractor 312. A connecting block 305 is fixedly connected to the top of the arc-shaped sleeve 306. A first spring 304 is fixedly connected to the top of the connecting block 305. One end of the first spring 304 is fixedly connected to the bottom of the fixed plate 303. There are two arc-shaped moving plates 307 on the inner wall of the arc-shaped sleeve 306. The two arc-shaped moving plates 307 are symmetrically arranged in the inner wall of the arc-shaped sleeve 306. A transverse airbag 309 is fixedly connected to one side of the lifting airbag 308.

[0049] The inner wall of the arc-shaped sleeve 306 is provided with a sliding groove 315. The arc-shaped moving plate 307 is slidably connected to the inner wall of the arc-shaped sleeve 306 through the sliding groove 315. There are two pull ropes 313, and one end of each pull rope 313 is fixedly connected to the top of the two arc-shaped moving plates 307 respectively.

[0050] A hollow telescopic rod 318 is fixedly connected to the top center of the connecting block 305. The top of the hollow telescopic rod 318 is hinged to the bottom of the fixed plate 303 through a hinge ball 317. There are two lifting airbags 308. A transverse airbag 309 is fixedly connected to the side of the two lifting airbags 308 that are close to each other. The elasticity of the transverse airbag 309 is greater than that of the lifting airbag 308. An air hole 319 is opened on the inner wall of the hollow telescopic rod 318.

[0051] When the slider 9 moves a long distance along the sliding track 6 carrying the plastic central control frame 8, it is prone to encountering turning paths. When encountering a turning path, the magnetic ball 302, the fixing plate 303, and the supported plastic central control frame 8 below the slider 9 will deviate from the center of the curve due to inertia. If the plastic central control frame 8 is fixed and cannot tilt, it will experience a rapid change in internal stress due to the lateral inertial force of the deviating direction. Furthermore, in the immediate demolding state, the internal stress and thermal stress are superimposed, easily causing deformation. At this point, the design of the magnetic ball 302 and the electromagnetic base 301, with the electromagnetic base 301 having a sensor inside to control the current in real time, allows for adjustable electromagnetic attraction, balancing the attraction force on the magnetic ball 302 with rotational flexibility. Ball 302 is electromagnetically attracted to the inner wall of electromagnetic base 301. Using ball bearings embedded in the inner wall of electromagnetic base 301, the magnetic ball 302 can rotate freely within the inner wall of electromagnetic base 301. The embedded ball bearings transform the sliding friction between electromagnetic base 301 and magnetic ball 302 into rolling friction, preventing changes in friction that could affect rotation when electromagnetic base 301 automatically adjusts its magnetic attraction force. Meanwhile, the fixed plate 303 and the first spring 304 connected below the magnetic ball 302 pull the connecting block 305, the arc-shaped sleeve 306, and the arc-shaped moving plate 307, causing the plastic central control frame 8 to rotate synchronously with the curve. This effectively balances lateral inertial forces, avoids sudden changes in internal stress, ensures the stability of the plastic central control frame 8 during turning, and reduces the risk of deformation.

[0052] Compared with traditional suction cup-type flexible clamping, by maximizing multi-point large-area wrapping vertical support, the plastic central control frame 8 rotates together with the turning process, so that all the horizontal forces on the plastic central control frame 8 are uniformly transformed into vertical forces, maximizing the use of the clamping method of the lifting airbag 308, and avoiding the problem of horizontal internal stress generated inside the plastic central control frame 8.

[0053] The first spring 304 connecting the fixed plate 303 and the connecting block 305 can function as the connecting block 305 and the arc sleeve 306, and can also adjust the distance between the connecting block 305 and the fixed plate 303 through elastic deformation when turning. When turning suddenly, the instantaneous pressure generated between the lifting airbag 308 and the plastic central control frame 8 is released to a certain extent by stretching the first spring 304, allowing the plastic central control frame 8 and the lifting airbag 308 to move downward synchronously. This transforms the instantaneous force into a force that gradually increases over a period of time, thereby effectively mitigating the instantaneous impact and avoiding deformation caused by instantaneous high pressure.

[0054] When the plastic central control frame 8 turns into a straight line after passing the center of the curve, it will gradually return to its original position due to its own weight and inertia. The first spring 304 will also return to its original position due to its own elasticity, ensuring that the plastic central control frame 8 and the lifting airbag 308 are re-fitted, maintaining stable support, and further reducing the risk of deformation. When the first spring 304 pulls the connecting block 305 to reset, the hollow telescopic rod 318 between the connecting block 305 and the fixed plate 303 plays a limiting role when the distance between the connecting block 305 and the fixed plate 303 changes through the opening of the surface air hole 319, avoiding the problem of swaying caused by excessive stretching or compression, ensuring that the entire transmission process is as smooth as possible, and reducing the deformation problem caused by pressure changes between the plastic central control frame 8 and the lifting airbag 308.

[0055] Example 3: Please refer to Figure 1-11 Based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution: an adjustment mechanism 4 is provided on the inner wall of the top of the arc-shaped moving plate 307. The adjustment mechanism 4 includes an arc-shaped telescopic plate 401. A connecting block 402 is fixedly connected to one end of the arc-shaped telescopic plate 401 away from the arc-shaped moving plate 307. The top of the connecting block 402 is fixedly connected to the inner wall of the arc-shaped sleeve 306. The other end of the arc-shaped telescopic plate 401 is fixedly connected to the top of the arc-shaped moving plate 307. A second spring is provided on the inner wall of the arc-shaped telescopic plate 401.

[0056] The top of the arc-shaped sleeve 306 has a connecting hole 403, and the inner wall of the connecting block 305 has a sealing cavity 405. The inner wall of the sealing cavity 405 is slidably connected to the sliding column 406, and the inner wall of the sealing cavity 405 is connected to the inner wall of the connecting hole 403 through the inside of the connecting block 305.

[0057] A push plate 407 is fixedly connected to the end of the sliding column 406 away from the connecting block 305. The push plate 407 has a circular disc-shaped structure. A distance sensor processor 408 is fixedly connected to one side of the connecting block 305. The distance sensor processor 408 has a circular sleeve-shaped structure. One side of the distance sensor processor 408 is fixedly connected to the outer wall of the connecting block 305.

[0058] When factory operations require increased efficiency to handle the production of large batches of plastic central control frames 8, workers often employ faster conveyor speeds. At these higher speeds, when navigating a bend, the airbag 308 and the plastic central control frame 8 are prone to swaying due to air resistance. This causes a slight shift in the plastic central control frame 8, which was originally stably positioned on the airbag 308, and the pressure between them increases simultaneously. The air inside the airbag 308 is compressed to the sides. On one hand, the lateral thrust of the air creates a horizontal component force on the curved moving plate 307. On the other hand, because the airbag 308 and the curved moving plate 307 are curved, the downward pressure also exerts a force on the curved moving plate 307. The horizontal force pushes the component, causing each arc-shaped moving plate 307 to slide away from each other to a certain extent. This force also overcomes the elastic force of the second spring in the inner wall of the arc-shaped telescopic plate 401, causing it to deform. The elastic force of the second spring can only overcome the deformation when the pressure is large and reaches a preset threshold. Otherwise, the second spring will not deform. This allows the two arc-shaped moving plates 307 to open and create a certain gap. This gap is far from enough to allow the plastic central control frame 8 to detach from the support of the lifting airbag 308. At the same time, the lifting deformation of the lifting airbag 308 and the arc-shaped moving plate 307 will change to the lifting and lateral compression of the airbag, achieving a dynamic balance between lifting and lateral support. This ensures that the plastic central control frame 8 will not sway left and right when turning at high speed.

[0059] Furthermore, when the pressure between the lifting airbag 308 and the plastic central control frame 8 increases instantaneously, the transverse airbag 309, which has greater elasticity, will be pushed out by the air pressure inside the lifting airbag 308. Since the elastic deformation threshold of the transverse airbag 309 under pressure is higher than that of the lifting airbag 308, gas will only flow into the transverse airbag 309 to inflate it when the air pressure inside the lifting airbag 308 rises above the preset threshold for the elastic deformation of the transverse airbag 309. Conversely, the transverse airbag 309 remains in a contracted state. At this time, when the transverse airbag 309 inflates, it further clamps the two sides of the plastic central control frame 8, thereby effectively fixing the position of the plastic central control frame 8 and preventing it from shifting during high-speed movement. This is specifically designed to address the additional pressure and shaking issues between the plastic central control frame 8 and the lifting airbag 308 caused by increased speed during high-speed movement, ensuring that the plastic central control frame 8 remains stable during high-speed movement, reducing the risk of deformation caused by increased speed, and improving overall work efficiency. Meanwhile, the elasticity design of the arc-shaped telescopic plate 401 and its second spring can be adjusted according to actual needs, flexibly coping with different working conditions and different types and weights of plastic central control frame 8;

[0060] Furthermore, under normal speed transmission conditions, since there is no excessive speed, the pressure between the lifting airbag 308 and the plastic central control frame 8 is insufficient to push the second spring in the arc-shaped telescopic plate 401 to deform. Therefore, under normal movement and transportation, the arc-shaped moving plate 307 and the lifting airbag 308 will not slide in the inner wall of the sliding groove 315, which also means that they will not wrap around the side of the plastic central control frame 8. This avoids the large area of ​​the side being covered, which would make it more difficult for the residual heat inside the plastic central control frame 8 to dissipate. At the same time, it reduces the pressure on the easily deformable parts of the plastic central control frame 8 by reducing the pressure on the plastic central control frame 8 caused by the temperature difference with other plastic parts of the plastic central control frame 8. By providing a single vertical lifting support force under normal movement conditions, without providing additional clamping, the problem of the plastic central control frame 8 being squeezed and deformed due to additional clamping in multiple directions is reduced.

[0061] Furthermore, during high-speed movement, when the two arc-shaped moving plates 307 separate, the hydraulic oil inside the arc-shaped telescopic plate 401 is squeezed and enters the connecting block 305 through the connecting hole 403 at the top of the connecting block 402 and the sliding groove 315. This pushes out the sliding column 406 and the push plate 407, which are slidably connected to the inner wall of the connecting block 305. The annular distance sensor processor 408 can identify the changes in the distance between the parallel push plates 407 through optical sensing, process the distance information, and control the inflation volume of the air pump 310 inside the lifting airbag 308 in real time according to the different distances. Once the two arc-shaped moving plates 307 separate during high-speed movement, the hydraulic oil inside the arc-shaped telescopic plate 401 is quickly replenished to the connecting block 402, ensuring the stable movement of the sliding column 406 and the push plate 407. The distance sensor processor 408 precisely adjusts... The air pump 310 inflates the lifting airbag 308 to increase the clamping force on the unstable plastic central control frame 8. This, combined with the sliding of the arc-shaped moving plate 307 and the lifting airbag 308, enhances the clamping force on the bottom and sides of the plastic central control frame 8. Therefore, not only can the clamping position be changed by moving the arc-shaped moving plate 307 and the lifting airbag 308, but the clamping force of the lifting airbag 308 on the plastic central control frame 8 can also be increased as the speed and inertia increase when passing through the apex of a bend. By assuming some of the risk of slight deformation at the clamping point, the problem of greater deformation risk caused by the extremely unstable shaking of the plastic central control frame 8 under high-speed movement is avoided. The advantages far outweigh the disadvantages, thus adaptively and dynamically adjusting to meet the stability requirements of the easily deformable plastic central control frame 8 in more high-speed movement scenarios, ensuring its reliable operation under complex working conditions.

[0062] When the hydraulic oil is used to extend and retract the arc-shaped telescopic plate 401, it only serves to push the sliding column 406 and the push plate 407, which have a smaller mass, to move. When the hydraulic oil inside the arc-shaped telescopic plate 401 is squeezed, the pressure is very small and will not interfere with the elasticity of the second spring.
