Description

Technical Field

[0001] This invention relates to the field of vehicle auxiliary equipment technology, and in particular to a ramp frame. Background Technology

[0002] With the development of society, vehicles have become one of the important means of transportation. During use, they often need to be maintained regularly, which requires the use of ramps to assist in raising them. For example, in drainage projects, the team needs to frequently wash the vehicles. In order to prevent water from accumulating inside the vehicle and to prevent the water inside from affecting the efficiency of driving, ramps are also needed to assist in raising them.

[0003] Most cars currently lack automatic parking systems or hill-start assist systems, making them prone to rolling backward when temporarily stopping or starting uphill. Automatic transmission cars typically use a combination of drive and the handbrake or foot brake to prevent rolling, while manual transmission cars sometimes require simultaneous control of the brake, clutch, and accelerator, adding considerable difficulty. Although some cars now integrate hill-start assist systems, these primarily rely on controlling the brake pads, using an electronic control system to determine if braking is necessary. Therefore, cars without automatic parking or hill-start assist systems are difficult to operate, easily rolling backward when starting uphill, potentially leading to accidents. Hill-start assist systems that control brake pads cause the brake pads, already frequently used downhill, to work even more frequently uphill, resulting in accelerated brake pad wear and potentially unpredictable and dangerous consequences on mountain roads. Furthermore, all cars that use hill-start assist systems that control brake pads are high-end sedans, and the related auxiliary electronic braking systems are expensive, complex in structure, and difficult to maintain after-sales.

[0004] In the process of using ramps, they often need to be placed on a certain ground. Inevitably, the ground may be uneven or slightly bumpy, causing the ramp to be unstable. When a vehicle drives onto the ramp, it will shake. In addition, the vehicle may deviate while driving on the ramp. If the deviation is too great, the wheels may fall off the ramp. Also, after a period of use, some crossbars may bend and be damaged. To save costs, it is necessary to facilitate the disassembly and replacement of individual crossbars and reduce the difficulty of the work. To solve the problems existing in the prior art, a ramp is proposed. Summary of the Invention

[0008] In a preferred embodiment of the uphill control method of the present invention, when the throttle depth is greater than the first threshold and the vehicle is in the forward gear, the positive traction force of the vehicle's engine is calculated, and when the positive traction force is greater than the reverse force generated by the vehicle's own weight and no brake pedal signal is detected, the automatic transmission controller controls the electronic parking system to stop working; or when the throttle depth is greater than the first threshold and the vehicle is in the forward gear, when the wheel output speed is detected to be positive and no brake pedal signal is detected, the automatic transmission controller controls the electronic parking system to stop working, and detects the vehicle's input speed signal; the automatic transmission controller calculates the positive traction force based on the input speed signal and the gear signal.

[0009] The uphill control method of this invention has the following advantages: by setting up the uphill control method, excessive wear of brake pads can be avoided, the driver's operating pressure can be reduced, driving safety can be improved, and fuel consumption can be effectively reduced, making the vehicle's uphill control method safer and more reliable.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0038] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0039] Example 1

[0040] Reference Figure 1This is the first embodiment of the present invention, which provides an uphill control method. When the driver accelerates, i.e., the throttle depth is greater than a first threshold and the vehicle is in a forward gear, the automatic transmission controller monitors the throttle pedal in real time and immediately calculates and determines whether the positive traction force of the vehicle's engine is greater than the reverse force generated by the vehicle's own weight through the speed control program. When the positive traction force of the engine is greater than the reverse force, the automatic transmission controller issues a command to stop the electronic parking system. The electronic parking system stops working, the parking state is released, and the vehicle can move forward normally.

[0041] Specifically, when the vehicle is going uphill, the throttle depth is detected; when the throttle depth is less than or equal to a first threshold, the gear position signal, wheel output speed signal, and brake pedal signal are detected; when the vehicle is in drive or neutral, the wheel output speed is negative, and no brake pedal signal is detected, the vehicle's automatic transmission controller controls the vehicle's electronic parking system to lock the parking ratchet to put the vehicle in a parked state.

[0042] Preferably, when the throttle depth is greater than a first threshold and the vehicle is in a forward gear, the forward traction force of the vehicle's engine is calculated, and when the forward traction force is greater than the reverse force generated by the vehicle's own weight and no brake pedal signal is detected, the automatic transmission controller controls the electronic parking system to stop working; or when the throttle depth is greater than the first threshold and the vehicle is in a forward gear, when a positive wheel output speed is detected and no brake pedal signal is detected, the automatic transmission controller controls the electronic parking system to stop working, and detects the vehicle's input speed signal; the automatic transmission controller calculates the forward traction force based on the input speed signal and the gear signal.

[0043] The positive traction force of the vehicle's engine can be calculated through the following steps: detecting the vehicle's input speed signal; the automatic transmission controller calculates the positive traction force based on the input speed signal and gear signal.

[0044] In summary, the hill-start control method of the present invention can greatly simplify the operation of the entire hill-start-stop-start process of the vehicle, and the entire process only requires operating the accelerator pedal.

[0045] It should be noted that the hill-start control method described above is used on automatic transmissions equipped with an electronic parking brake system. This electronic parking brake system refers to a system that controls the parking mechanism inside the automatic transmission via a motor, unlike an electronic parking brake system that controls the brake pads. Specifically, the automatic transmission controller collects five signals: gear position signal, wheel output speed signal, input speed signal, and signals exchanged with the engine controller for throttle opening and brake pedal position. Furthermore, the automatic transmission controller determines if the vehicle has a tendency to roll backward. If so, it controls the brakes. When the driver depresses the accelerator pedal, the automatic transmission controller deactivates the electronic parking brake system, releasing the ratchet and allowing the vehicle to move forward.

[0046] Example 2

[0047] Reference Figure 2 , 8 ~10 is the second embodiment of the present invention. This embodiment provides a slope frame. When a single cross span T-1 on the slope frame body T is bent and damaged, in order to avoid discarding the whole frame, it is necessary to replace the single cross span T-1. By setting a quick-release component 400, when it is necessary to disassemble, the pull rings can be pulled to both sides to pull the cross span T-1 outward. When it is necessary to replace it with a new one, it can be installed by simply pressing it. This is very convenient and also reduces economic costs.

[0048] Specifically, the slope frame body T includes a cross frame T-1, a side wing frame T-2 disposed on the outer wall of the cross frame T-1, a support beam T-3 disposed on the inner wall of the side wing frame T-2, and a first mounting plate T-21 disposed on the side wing frame T-2; and a drive assembly 100, including a movable channel 101 extending through the outer wall of the cross frame T-1, a button 101a disposed inside the movable channel 101, a push plate 101a-1 disposed on the outer wall of the button 101a, and a movable column 102 disposed on the outer wall of the push plate 101a-1; and a stabilizing assembly 200, including a connecting plate 201, a pressing block 202 disposed outside the connecting plate 201, and a first connecting block 201 disposed at one end of the connecting plate 201. a) First slide groove 201b, second slide groove 201c, and second connecting block 201d; and b) Protective assembly 300, including a rotating column 301, a turntable 302 disposed at one end of the rotating column 301, a third slide groove 302a penetrating the outer wall of the turntable 302, a first slide column 302a-1 movably disposed inside the third slide groove 302a, and a protective plate 307 disposed outside the side wing frame T-2; and c) Quick-release assembly 400, including a first connecting cylinder 401 disposed at one end of the cross frame T-1, a second connecting cylinder 402 disposed at one end of the first connecting cylinder 401, a third connecting cylinder 403 disposed at one end of the second connecting cylinder 402, and a first inclined surface 403a disposed at one end of the third connecting cylinder 403.

[0049] The vehicle includes several crossbeams T-1 for wheel passage. Typically, two ramp bodies T are used together, positioned at a suitable distance to raise one side of the vehicle. Several support beams T-3 are provided. Several buttons 101a are preferably provided, all connected to a push plate 101a-1 at their bottom. When a wheel passes over, gravity is applied to the button 101a to ensure the protective plate 307 remains upright, acting as a barrier. Furthermore, the button 101a can preferably have a friction texture. The button 101a, originally gently raised, can also influence the driver's psychology, similar to a speed bump, preventing excessive initial speed and thus improving comfort and safety. Two movable columns 102 are provided. When a button 101a is pressed down, it pushes the push plate 101a-1 downwards, further pushing the movable columns 102. Four connecting plates 201 are preferably provided to further press the pressing block 202 down to the ground. The surface increases the contact area, ensuring the slope frame body T is placed stably. Through adaptive adjustment via connecting rods, it can adapt to small-scale uneven ground, making the slope frame body T more stable when the vehicle is in motion, reducing sway. Two protective plates 307 are preferably provided, located on both sides of the slope frame body T. When a wheel passes over them, the protective plates 307 rise, effectively preventing novice or inattentive drivers from deviating from the trajectory and falling off the slope frame body T, thus reducing safety hazards. When the vehicle is moving, the protective plates 307 can guide the direction, facilitating timely correction by the driver. If the vehicle accidentally deviates from the trajectory, it will also hit the protective plates 307, further acting as a buffer to help adjust the driving trajectory. Each crossbeam T-1 has quick-release components 400 on both sides of its bottom. The diameter of the first connecting cylinder 401 is slightly larger than that of the second connecting cylinder 402; the diameter of the fourth connecting cylinder 403b is slightly smaller than that of the third connecting cylinder 403.

[0050] Preferably, one end of the third connecting cylinder 403 is provided with a fourth connecting cylinder 403b, one end of the first mounting plate T-21 is provided with a second mounting plate 404, one end of the second mounting plate 404 is provided with a positioning post 404a, and the positioning post 404a is movably engaged with the fourth connecting cylinder 403b. One end of the first mounting plate T-21 is provided with a movable block 405, the outer wall of the movable block 405 is provided with a second inclined surface 405a, and the second inclined surface 405a is movably engaged with the first inclined surface 403a. One end of the movable block 405 is provided with a roller 405b.

[0051] When replacing a damaged cross-frame T-1, the fourth connecting cylinder 403b at its bottom can be directly aligned with the positioning post 404a. During the downward pressing process, the first inclined surface 403a and the second inclined surface 405a engage, and the movable block 405 slides further to both sides. When the second connecting cylinder 402 is pressed down to the bottom, the movable block 405 is bounced back and locked at the top of the third connecting cylinder 403, thus completing the fixation. This is very convenient as it only requires one pressing action. When disassembly and replacement are required, the pull ring 408b can be pulled outward to release the engagement of the movable block 405, and the cross-frame T-1 can be pulled outward further. Generally, the slope frame body T is directly welded together. If a single cross-frame T-1 is damaged, repair is very inconvenient. This setting improves overall convenience and greatly reduces economic costs. The roller 405b can slide on the first mounting plate T-21.

[0052] Preferably, a third mounting plate 407b is provided at one end of the first mounting plate T-21, a fixing cylinder 407 is provided through the outer wall of the third mounting plate 407b, a retaining ring 407a is provided on the outer wall of the fixing cylinder 407, a cover plate 408 is movably provided on the outside of the fixing cylinder 407, a telescopic column 406 is provided between the cover plate 408 and the movable block 405, a third elastic element 406a is sleeved on the outer wall of the telescopic column 406, a pull column 408a is provided at one end of the cover plate 408, and a pull ring 408b is provided at one end of the pull column 408a.

[0053] The third mounting plate 407b is fixedly mounted on the first mounting plate T-21, and has a through hole inside for placing the fixing cylinder 407; the retaining ring 407a is fixedly mounted on one side of the fixing cylinder 407, and the cover plate 408 is movably mounted on the other side of the fixing cylinder 407; one end of the telescopic column 406 is connected to the movable block 405, and the other end is fixedly connected to the cover plate 408 through the retaining ring 407a and the fixing cylinder 407; the pull column 408a is fixedly connected to the cover plate 408; the third elastic element 406a is preferably a compression spring; pulling the pull ring 408a can further drive the telescopic column 406 connected to the cover plate 408, and further pull the movable block 405 outward to make it engage with the release lock.

[0054] In summary, when a single cross span T-1 on the slope frame body T is damaged or bent, in order to save economic costs and reduce maintenance difficulty, a quick-release component 400 is set up. By pulling the pull rings 408b on both sides, the movable block 405 can be pulled open, allowing the damaged cross span T-1 to be pulled out. When it is necessary to replace and install a properly functioning one, simply press down to complete the installation. The whole process is very convenient and easy to operate.

[0055] Example 3

[0056] Reference Figures 2-7This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that by setting up a squeezing block 202, when the vehicle drives onto the slope frame body T, the button 101a will be pressed, which will cause the connecting plate 201 to press down. The squeezing block 202 will then adjust accordingly and press steadily on the ground to ensure that the vehicle drives smoothly and avoids the problem of swaying with the slope frame body T. At the same time, a protective plate 307 is set up. When the wheel presses on the slope frame body T, the protective plate 307 will stand up to block it and prevent the wheel from deviating from the track, so as to make timely adjustments and solve the problem mentioned above.

[0057] Specifically, the push plate 101a-1 is provided with an installation frame 103 on the outside, and a first connecting column 103a is provided between the installation frame 103 and the support beam T-3. A second connecting column 103b is provided at one end of the installation frame 103, and an installation plate 103c is provided at one end of the second connecting column 103b. A first elastic element 103b-1 is sleeved on the outside of the second connecting column 103b, and a third connecting column 103c-1 is provided between the installation plate 103c and the support beam T-3.

[0058] Preferably, a movable plate 102a is movably provided between the mounting frame 103 and the mounting plate 103c, and the outer wall of the movable plate 102a is fixedly connected to the connecting plate 201. A rotating cylinder 104 is movably provided inside the movable plate 102a. A fourth sliding groove 104a is provided on the outer wall of the rotating cylinder 104. A through hole 102a-1 is provided on the outer wall of the movable plate 102a. A second sliding column 102a-11 is movably provided inside the through hole 102a-1, and the second sliding column 102a-11 is movably engaged with the fourth sliding groove 104a.

[0059] The first connecting column 103a connects the fixed slope frame body T and the mounting frame 103. The mounting frame 103 is hollow to allow the movable column 102 to pass through and press down the movable plate 102a. The third connecting column 103c-1 connects the fixed slope frame body T and the mounting plate 103c. The mounting plate 103c has a through hole in the middle, through which the rotating column 301 can pass and be fixedly placed without affecting its rotation. The second connecting column 103b connects the mounting frame 103 and the mounting plate 103c. The first elastic element 103b-1 is preferably a compression spring. A spring, facilitating reset, is sleeved on the outer wall of the second connecting post 103b and positioned between the movable plate 102a and the mounting plate 103c. The movable plate 102a has a through groove in the middle for the rotating cylinder 104 to pass through, and through holes on both sides of the movable plate 102a to facilitate sliding of the movable plate 102a on the second connecting post 103b. The fourth sliding groove 104a is divided into an upper sliding groove and a lower sliding groove, which cooperate with the second sliding post 102a-11. When the movable plate 102a slides down, the second sliding post 102a-11 and the fourth sliding groove 104a cooperate with each other to further rotate the rotating cylinder 104.

[0060] In summary, when the wheel slides over the crossbeam T-1, button 101a is pressed, which further presses down the movable column 102 and pushes the movable plate 102a down, thereby causing the connecting plate 201 to slide down and pressing the pressing block 202 onto the ground. Through linkage adjustment, it can adapt to uneven surfaces, further making the slope frame body T more stable, thus preventing the wheel from shaking when it drives over. At the same time, the rotation of the rotating drum 104 will further raise the protective plate 307, thereby acting as a barrier to prevent the wheel from deviating from its trajectory. In this way, the problems existing in the prior art can be solved.

[0061] Example 4

[0062] Referring to Figures 2-7, this is the fourth embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that by setting the first sliding groove 201b and the second sliding groove 201c, when encountering some uneven ground, the third connecting block 201b-1 and the fourth connecting block 201c-1 slide inside the first sliding groove 201b and the second sliding groove 201c respectively for adjustment. At the same time, the rubber pad 202a can increase the friction and prevent sliding.

[0063] Specifically, a third connecting block 201b-1 is movably provided inside the first chute 201b, a fourth connecting block 201c-1 is movably provided inside the second chute 201c, a first connecting rod 203 is movably provided between the first connecting block 201a and the extrusion block 202, a second connecting rod 203a is movably provided between the extrusion block 202 and the third connecting block 201b-1, and a third connecting rod 203b is movably provided at one end of the second connecting rod 203a, and one end of the third connecting rod 203b is movably connected to the extrusion block 202.

[0064] Preferably, a fourth connecting rod 203c is movably provided between the extrusion block 202 and the fourth connecting block 201c-1, and a fifth connecting rod 203d is movably provided at one end of the fourth connecting rod 203c, and one end of the fifth connecting rod 203d is movably connected to the extrusion block 202. A sixth connecting rod 203e is provided between the extrusion block 202 and the second connecting block 201d, and a rubber gasket 202a is provided at one end of the extrusion block 202.

[0065] The compression block 202 is preferably provided in several quantities, and the number can be set according to the specific slope frame body T. The compression block 202 is movably connected to the connecting plate 201 through several connecting rods. The compression block 202 can be used for different irregular ground. When there are raised or depressed parts on the ground, the compression block 202 will press against the ground, and the third connecting block 201b-1 and the fourth connecting block 201c-1 will slide in the first sliding groove 201b and the second sliding groove 201c respectively, so that it can make more full contact with the ground. At the same time, the compression block 202 is relatively small, so it can play a stabilizing role in this local area. The rubber pad 202a not only increases the friction and prevents sliding, but also deforms accordingly, helping the compression block 202 to make more full and stable contact with the ground, thereby preventing the slope frame body T from being placed unstable and the vehicle from shaking along with it. Through this setting, the slope frame body T can adapt to different irregular ground.

[0066] In summary, when the wheel slides over the crossbeam T-1, button 101a is pressed, the movable column 102 presses down and pushes the movable plate 102a down, further pressing down the connecting plate 201, thereby pushing the pressing block 202 into full contact with the ground. During the pressing process, the third connecting block 201b-1 and the fourth connecting block 201c-1 slide. If there are uneven areas on the ground, they can be adjusted and pressed up accordingly. At the same time, rubber pads 202a are set to further assist in anti-slip. Meanwhile, the contact area between the pressing block 202 and the ground can be increased, which can further stabilize the slope frame body T, thereby preventing the wheel from shaking during operation.

[0067] Example 5

[0068] Referring to Figures 1-10, this is the fifth embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that by setting a movable rod 306, when the turntable 302 rotates, the movable rod 306 is further pulled down, thereby pulling the rotating shaft 307b-2, which in turn drives the third mating block 307b to stand up, thereby enabling the protective plate 307 to stand up, so as to play a protective and blocking role and prevent the wheel travel trajectory from deviating.

[0069] Specifically, one end of the rotating column 301 is fixedly connected to the rotating cylinder 104, one end of the first sliding column 302a-1 is provided with a sliding rod 302b, the outer wall of the support beam T-3 is provided with a fifth sliding groove 302b-1, and the fifth sliding groove 302b-1 is movably engaged with the sliding rod 302b. The support beam T-3 is provided with a movable groove 303 and a receiving cavity 303a, respectively, and one end of the sliding rod 302b is provided with a shaped block 303b.

[0070] Preferably, the outer wall of the irregular block 303b has a slope 303b-1, the outer wall of the irregular block 303b has a stop block 303b-2, the outer wall of the support beam T-3 has a support plate 304, one end of the support plate 304 has a sixth sliding groove 304a, and the sixth sliding groove 304a is movablely engaged with the irregular block 303b.

[0071] Preferably, the outer wall of the support beam T-3 is provided with a fixing plate 305, the outer wall of the fixing plate 305 is provided with a through groove 305a, and a movable rod 306 is movably provided inside the through groove 305a. The outer wall of the movable rod 306 is fitted with a second elastic element 306a. One end of the movable rod 306 is provided with a fall prevention plate 306b, and one end of the fall prevention plate 306b is movably provided with a pulley 306b-1. The outer wall of the pulley 306b-1 is movably engaged with the slope surface 303b-1.

[0072] Two sliding rods 302b are arranged on the left and right sides. A sliding rod 303b is connected to a shaped block 303b via a movable groove 303. The receiving cavity 303a facilitates the movement of the shaped block 303b. The pulley 306b-1 is initially positioned on the ground where the slope of the shaped block 303b is higher. When the pulley moves towards the slope frame body T, the rotating column 301 rotates, further rotating the turntable 302. The third sliding groove 302a engages with the first sliding column 302a-1, causing the sliding rod 302b to pull the shaped block 303b back, thereby… The pulley 306b-1 slides on the slope 303b-1 and falls to a lower part of the slope, thereby pulling down the movable rod 306; the stop block 303b-2 is to prevent the pulley 306b-1 from falling; the sixth slide groove 304a is movably engaged with the irregular block 303b to limit its sliding direction; the movable rod 306 slides in the through groove 305a, limiting its movement direction; the second elastic element 306a is a compression spring, sleeved on the outer wall of the movable rod 306, and located between the fixed plate 305 and the anti-fall plate 306b.

[0073] Preferably, the outer wall of the side wing frame T-2 is provided with a plurality of first mating blocks 307a-1, the outer wall of the protective plate 307 is provided with a plurality of second mating blocks 307a, and the second mating blocks 307a are movably mated with the first mating blocks 307a-1. The outer wall of the protective plate 307 is provided with a third mating block 307b, and the outer wall of the side wing frame T-2 is provided with a fourth mating block 308. The outer wall of the fourth mating block 308 is provided with a seventh sliding groove 308a.

[0074] Preferably, the outer wall of the third mating block 307b is provided with a connecting rod 307b-1, and the outer wall of the connecting rod 307b-1 is provided with an eighth sliding groove 307b-11. A rotating shaft 307b-2 is movably provided between the seventh sliding groove 308a and the eighth sliding groove 307b-11. The outer wall of the fourth mating block 308 is provided with a limiting plate 308b, one end of the limiting plate 308b is provided with a first limiting post 308b-1, the outer wall of the side wing frame T-2 is provided with a second limiting post 308c, the outer wall of the rotating shaft 307b-2 is provided with a connecting frame 307b-21, and the outer wall of the connecting frame 307b-21 is fixedly connected to the movable rod 306.

[0075] The first mating block 307a-1 and the second mating block 307a are movably connected by a shaft. When the third mating block 307b and the fourth mating block 308 are flipped, the first mating block 307a-1 and the second mating block 307a also rotate accordingly. Preferably, there are two fourth mating blocks 308, with the third mating block 307b positioned between them. The eighth slide groove 307b-11 is placed at an angle and aligned with the seventh slide groove 308a via a rotating shaft 307b-2. The limiting plate 308b is located at the bottom of the fourth mating block 308. The first limiting post 308b-1 is used to abut against the connecting rod 307b-1. The second limiting post 308c is used to abut and limit the plate 307 after it is flipped. When the wheels are traveling on the ramp body T, pulling down the movable rod 306 will cause the protective plate 307 to flip up, providing protection and preventing the vehicle from deviating significantly from its trajectory and posing a safety hazard. When not in use, the protective plate 307 will not flip up and will be placed horizontally, making it easier to store and saving space. Generally, two ramp bodies T are used together. When the protective plate 307 is placed horizontally, the two inclined surfaces of the ramp body T can fit together to form a rectangle when stored, thus saving storage space. If it were flipped up vertically, it would interfere with the storage of the ramp body T. Especially for manufacturers who want to save space, since there are many ramp bodies T, saving space is very necessary.

[0076] In summary, by having the vehicle travel on the slope frame body T, the rotating column 301 rotates, causing the turntable 302 to rotate. The sliding rod 302b then slides back, pulling the irregular block 303b back, causing the pulley 306b-1 to fall onto a lower slope surface. This further pulls the movable rod 306 downwards, causing the connecting frame 307b-21 to pull the rotating shaft 307b-2 downwards. This causes the protective plate 307, connected to the third mating block 307b, to flip, providing guidance and protection. In this way, if the wheels deviate from the driving trajectory, the protective plate 307 can act as a buffer, allowing for timely correction and adjustment, greatly reducing safety hazards and solving existing problems.
