Description

Technical Field

[0001] This invention relates to the field of PCS type garage technology, and more particularly to a rack and pinion transmission mechanism applied to PCS type. Background Technology

[0002] With the rapid development of China's economy, the continuous improvement of people's living standards, and the continuous increase in car ownership, in order to meet market demand, a wave of development of multi-level parking equipment has gradually emerged in the market, making the competition of multi-level parking equipment fierce and the survival of the fittest. Urban parking, especially the demand for high-rise and high-end parking garages, is strong, which has also led parking equipment manufacturers to continuously develop in the direction of high-rise and high-end parking garages.

[0003] Vertical lift parking systems (PCS) are widely favored by the market due to their small footprint, high space utilization, fast speed, and efficient parking. However, the following issues still exist during their use:

[0004] 1. When a car is entering or leaving the warehouse, the support frame is usually raised and lowered by stretching steel cables through rack and pinion transmission modules on both sides. During the raising and lowering of the vehicle, the rack and pinion transmission modules on both sides may be out of sync, causing unstable raising and lowering, which may lead to bending and damage to the support frame.

[0005] 2. When drivers attempt to park in a parking space, many drivers are unable to reverse into the space accurately. The car is parked at an angle, and the uneven force on both ends of the comb support rod can easily cause damage. The rigid lifting mechanism requires the driver to readjust the car, which is time-consuming and laborious, thus reducing parking efficiency.

[0006] 3. Some garages have a fixed overall footprint and limited internal space. When arranging parking spaces, some corner areas may be too small to accommodate regular cars, resulting in wasted space. Furthermore, when some small new energy vehicles drive onto the bottom comb platform inside the garage, the length of the vehicle body on both ends of the comb platform may become unbalanced, making it very unstable when the subsequent lifting comb rack is used to raise and park the car. To address this, we propose a rack and pinion transmission mechanism for PCS type. Summary of the Invention

[0023] Beneficial effects

[0024] This invention provides a rack and pinion transmission mechanism applicable to PCS type, which has the following beneficial effects:

[0025] (1) The rack and pinion transmission mechanism applied to the PCS type is equipped with a drive mechanism and a garage mechanism. When the fixed rod is squeezed, the movable block contacts the position of the first detection block and sends a signal to the external controller and counts once. When it is not squeezed, the first spring causes the movable block to reset away from the first detection block. The meshing state of the first gear and the first rack plate can be detected by the number of counts and frequency. There are no misaligned teeth and the meshing speed. When the speeds of the two sets of mounting bodies are different, the mounting body position at the slower end is not energized. The first motor is energized to drive the first gear to increase the speed, thus ensuring that the lifting speed of the mounting bodies on both sides is the same and ensuring lifting stability. When lifting, the connecting block contacts the anti-fall plate and rotates it into the mounting groove. After passing through, the anti-fall plate is reset under the counterweight of the support plate, which plays a role in preventing the connecting block from falling. When descending, the connecting block moves down and the position is determined by the detection module. The first electric push rod at the corresponding position pushes the anti-fall plate to rotate and reset, so that the connecting block descends and unlocks step by step, still playing a role in preventing falling. In this way, when lifting the vehicle, the lifting speed on both sides can be detected and adjusted. At the same time, it plays a role in preventing falling when lifting and descending, ensuring the stability of vehicle lifting.

[0026] (2) The rack and pinion transmission mechanism applied to the PCS type is equipped with a base plate assembly and a lifting mechanism. The vehicle platform drives the vehicle to turn around, and the connecting shaft is driven by the moving body to adjust the front and rear position of the vehicle. The cooperating block drives the clamping rod to continuously insert into the second clamping groove, so that the extrusion block is pressed against the side of the vehicle. When the pressure sensors of the extrusion blocks on both sides receive pressure feedback, it is determined that the left and right position of the vehicle has been adjusted. At the same time, the clamping rod corresponding to the wheel position continues to be inserted into the second clamping groove, and the clamping rod corresponding to other wheel positions disengages from the second clamping groove and engages with the first clamping groove position. This allows the vehicle to be automatically adjusted and detected according to different vehicle types. For normal vehicles, the vehicle adjustment position is centered and corresponds to the large parking space. For microcars, the vehicle adjustment position is on one side and corresponds to the small parking space. In this way, the vehicle position can be automatically adjusted and detected according to different vehicles. In addition, the small parking space is set up to place microcars when space is limited, making full use of space and avoiding the need for adjustment if the driver does not reverse into the parking space accurately, thus improving parking efficiency.

[0027] (3) The rack and pinion transmission mechanism applied to the PCS type is equipped with a vehicle carrying mechanism and a lifting mechanism. When parking, the lifting frame and lifting rod descend and intersect with the comb teeth of the vehicle carrying rod so that the vehicle is placed on the upper side of the vehicle carrying rod. When the second detection block detects the passing of the lifting rod, the sixth electric push rod pulls the connecting rod so that the limiting plate slides inside the limiting groove. The limiting rod corresponding to the wheel position is pressed against the side of the wheel and slides into the limiting plate. The limiting rod corresponding to the side of the wheel extends out of the limiting groove under the support of the second spring to limit the wheel. Conversely, when retrieving the vehicle, the corresponding lifting rod is locked at the side position of the lifting frame and rises. The lateral movement module drives the mounting plate to move the vehicle laterally. When the lifting rod passes the second detection block, the sixth electric push rod pushes the connecting rod to reset the limiting rod and the limiting plate. The lateral movement module drives the mounting plate to reset the lifting frame and the lifting rod to lower the vehicle to complete the retrieval. The position of the comb teeth of the lifting vehicle can be changed according to different parking spaces of different sizes, making full use of space while avoiding vehicle interference when entering and leaving the parking space.

[0054] Furthermore, such as Figure 14 and Figure 15 As shown, the vehicle-carrying mechanism 5 includes mounting plates 51 equidistantly arranged inside the main frame 11. The mounting plates 51 are rectangular plates. Lateral movement modules 52 are fixedly mounted on both sides of the mounting plates 51 and are located inside the guide rail grooves of the main frame 11. Each lateral movement module 52 consists of a rectangular plate, a synchronous belt, a drive motor, and rollers. The drive motor drives the rollers to roll along the inner wall of the guide rail grooves of the main frame 11, thus enabling the mounting plates 51 to move laterally. This is considered prior art. Vehicle-carrying components are fixedly mounted equidistantly on both sides of the mounting plates 51. The vehicle-carrying pole 53 is a rectangular pole. Second detection blocks 54 are fixedly installed on both sides of the vehicle-carrying pole 53. The second detection blocks 54 are photoelectric sensors (E-base plate assembly 3FA-DN main frame 11). The second detection blocks 54 can detect when the lifting pole 43 passes by. Limiting grooves 55 are symmetrically and equidistantly formed on the upper side of the vehicle-carrying pole 53. The limiting grooves 55 are rectangular grooves. Limiting plates 56 are movably installed inside the limiting grooves 55. The limiting plates 56 are rectangular plates with cylindrical grooves on their sides. A limiting rod 57 is movably installed in the internal cylindrical groove of the 6. The limiting rod 57 is a cylindrical rod with a "T"-shaped cross-section. A second spring 58 is fixedly connected between the limiting rod 57 and the side of the limiting plate 56, and the second spring 58 is movably sleeved on the side of the limiting rod 57. The second spring 58 is existing technology and will not be described in detail here. The second spring 58 can provide elastic support for the limiting rod 57. A movable cavity 59 is opened inside the vehicle-carrying rod 53 at the position corresponding to the limiting groove 55, and the movable cavity 59 is connected to the inside of the limiting groove 55. The movable cavity 59 is a rectangular groove. A connecting rod 591 is movably installed inside the movable cavity 59 and is fixedly connected to the side of the limiting plate 56. The connecting rod 591 is a rectangular rod. A sixth electric push rod 592 is fixedly installed on the inner wall of the movable cavity 59 and is fixedly connected to the side of the connecting rod 591. The sixth electric push rod 592 is existing technology and will not be described in detail here. When the sixth electric push rod 592 pulls the connecting rod 591, it can drive the limiting plate 56 to slide inside the limiting groove 55.

[0055] Working principle of the invention:

[0056] In use, firstly, the base plate assembly 3 and the lifting mechanism 4 work together to adjust the vehicle position. Specifically: the vehicle is guided by the guide plate 32 to the upper position of the vehicle platform 33. The lifting rod 43 raises the vehicle platform 33, and the rotating motor drives the rotating gear to rotate the lifting rod 43, causing the vehicle platform 33 to rotate 180 degrees and descend to complete the vehicle turning operation. The light curtain assembly 411 roughly detects the position of the vehicle tires. The second electric push rod 353 pushes the mating plate 36 upward, causing the connecting shaft 362 to disengage from the connecting cavity 332. The second motor 352 drives the second gear 351 and the second rack plate 34 to mesh, causing the mating plate 36 to move. In this way, the two sets of mating... After the connecting shaft 362 on the side of plate 36 clamps the tire, the third electric push rod 441 pushes the auxiliary component 44 upward above the lifting rod 43 so that it fits against the bottom of the vehicle. At this time, one set of third motors 361 drives the connecting shaft 362 to rotate for one second and then stop. The presence or absence of a handbrake is determined by whether the friction between the connecting shaft 362 and the wheel causes the other set of connecting shafts 362 to rotate. If there is no handbrake, the rotation of the other set of connecting shafts 362 drives the other set of non-powered third motors 361 to rotate. The angle sensor inside the third motor 361 feeds back to the external controller, which then issues an alarm to notify the owner. Then, the vehicle size is determined based on the wheelbase detected by the second slot 412. Whether the vehicle's parking position is standard, the connecting shaft 362 clamps the wheel and, driven by the movable body 35, can move the vehicle back and forth to adjust its position. The ball bearings on the side of the auxiliary component 44 provide guidance and support. After the front and rear adjustment is completed, the fourth electric push rod 455, which controls the relative position of the wheel, pushes the pressing block 456 upward according to the current wheel position. The fourth motor 45 drives one set of third gears 451 to rotate, and the other two sets of third gears 451 drive the mating rod 452 to rotate and engage with the mating block 453 threadedly. The mating block 453 drives the locking rod 454 to continuously insert into the second locking groove 412, so that the pressing block 456 is pressed against the side of the vehicle. When the pressure sensors of the pressing blocks 456 on both sides receive pressure feedback, the judgment is made. Once the vehicle's left and right positions are adjusted, the fourth motor 45 drives the locking rod 454 to disengage from the second locking slot 412 and engage with the first locking slot 334. The third electric push rod 441 pulls the auxiliary component 44 back to the inside of the lifting rod 43. The constraint block 462 releases the wheel and resets it to the connecting cavity 332 in a similar position to prevent wheel interference. The fifth electric push rod 463 pushes the constraint rod 46 to move the constraint block 462, which presses against the side of the locking rod 454 for fixation. This completes the vehicle adjustment. For a normal vehicle, the adjusted position is centered, corresponding to a large vehicle position; for a microcar, the adjusted position is to one side, corresponding to a small vehicle position.

[0057] Then, the drive mechanism 2 and the garage mechanism 1 work together to lift the vehicle and prevent it from falling. Specifically, when the vehicle is in normal operation, the first gear 23 on the side with the detection module 27 is driven by the first motor 24 and meshes with the first rack plate 22, causing the mounting body 21 to move. The mounting body 21 pulls the lifting cable 26, causing the lifting frame 41 to move and drive the lifting rod 43 to lift the vehicle. Another set of first gears 23 also meshes with the first rack plate 22, causing the first motor 24 to rotate manually without power. The angle sensor inside the third motor 361 feeds back to the external controller, which can detect the movement of the mounting body 21. When the synchronous fixing rod 274 is squeezed, the movable block 273 contacts the position of the first detection block 272, and a signal is sent to the external controller and counted once. When it is not squeezed, the first spring 275 causes the movable block 273 to return to the position away from the first detection block 272. The first gear 23 and the first rack plate 22 are detected by the number of counts and the frequency. The engagement state of the strip plate 22 includes whether there is misalignment and engagement speed. When the speeds of the two sets of mounting bodies 21 are different, the mounting body 21 with the slower speed is not energized, and the first motor 24 is energized to drive the first gear 23 to increase the speed. This ensures that the lifting speeds of the two mounting bodies 21 are the same, thus ensuring lifting stability. When the microcar is in the case of the microcar, the first gear 23 on the side of the mounting body 21 that is biased towards the microcar is fully driven, and the first gear 23 on the other side with the detection module 27 is driven. Similarly, speed detection and adjustment are performed to ensure lifting stability. When lifting, the connecting block 42 contacts the anti-fall plate 13 and rotates it into the mounting groove 12. After passing through, the anti-fall plate 13 is reset under the counterweight of the support plate 14, which serves as an anti-fall limit for the connecting block 42. When descending, the connecting block 42 moves down and its position is determined by the detection module 27. The first electric push rod 15 at the corresponding position pushes the anti-fall plate 13 to rotate and reset, so that the connecting block 42 descends and unlocks step by step, still serving as an anti-fall function.

[0058] Finally, the vehicle-carrying mechanism 5 and the lifting mechanism 4 work together to enable vehicle parking and retrieval. Specifically: when parking, the drive motors of the large and small parking space lateral movement modules 52 drive the rollers to roll on the inner wall of the guide rail groove of the main frame 11, causing the mounting plate 51 to move laterally. The lifting frame 41 and the lifting rod 43 descend and intersect with the comb teeth of the vehicle-carrying rod 53, placing the vehicle on the upper side of the vehicle-carrying rod 53. When the second detection block 54 at the corresponding position detects the passage of the lifting rod 43, the sixth electric push rod 592 pulls the connecting rod 591, causing the limiting plate 56 to slide inside the limiting groove 55. The limiting rod 57 at the corresponding wheel position presses against the side of the wheel and slides into the limiting plate. Inside 56, the limiting rod 57, corresponding to the side position of the wheel, extends out of the limiting groove 55 under the support of the second spring 58 to limit and constrain the wheel. The lateral movement module 52 drives the mounting plate 51 to reset and complete the parking. Conversely, when retrieving the vehicle, the corresponding lifting rod 43 is locked at the side position of the lifting frame 41 and rises. The lateral movement module 52 drives the mounting plate 51 to move the vehicle laterally. The lifting rod 43 passes through the second detection block 54, causing the sixth electric push rod 592 to push the connecting rod 591, thereby resetting the limiting rod 57 and the limiting plate 56. The lateral movement module 52 drives the mounting plate 51 to reset the lifting frame 41 and drive the lifting rod 43 to lower the vehicle and complete the retrieval.
