Description

Technical Field

[0001] This invention relates to the field of pit-type mechanical parking equipment technology, and in particular to a double-row pit-type mechanical parking equipment that can ensure the passage of vehicles in the front row. Background Technology

[0002] Based on the vehicle parking method, parking can be divided into single-row parking, double-row parking, and triple-row parking, collectively referred to as double-row parking. Pit-type parking involves digging a pit underground to construct parking spaces below ground level. Traditional double-row pit-type mechanical parking equipment typically consists of two rows and three layers: one underground, one above ground, and one above ground. During retrieval, to ensure passage for the front row, an empty space is reserved on the ground level in each row. During use, the aisle panel is moved laterally to this empty space. To maintain passage for the rear row, the aisle panel is usually placed below the vehicle platform. When the following train departs, the falling and rising of the vehicles impacts the aisle panel. This impact during vehicle movement causes deformation of the aisle panel, reducing its lifespan. Therefore, we propose a double-row pit-type mechanical parking equipment that ensures passage for the front row. Summary of the Invention

[0010] Beneficial effects

[0011] This invention provides a double-track pit-type mechanical parking device that ensures the passage of vehicles in the front. It has the following beneficial effects:

[0012] (1) This double-track pit-type mechanical parking equipment, which ensures the smooth passage of the front train, reduces the swaying sensation of the moving plate by using a buffer structure to slow down the downward movement of the moving plate when the front wheels of the car move above the guide plate. When the front wheels of the car pass the position of the first support rod, the swing of the first support rod causes one end of the guide plate on the moving plate to move upward again. The buffer structure then pushes against the bottom of the moving plate to meet the pressure of the rear wheels of the car. The car moves on the moving plate, and the first and second support rods fit into the adapter grooves to keep the car in a stable state when moving on the moving plate. When the front of the car passes the second support rod, the center of gravity of the car is at the position of the front of the car, causing the moving plate to swing around the second support rod as the center of rotation. When the movable plate applies pressure to the locking structure, the end of the movable plate away from the guide plate is fixed by the locking structure. At this time, the side of the movable plate closest to the ground is flush with the ground. The front wheels of the car drive out of the garage through the movable plate. When the rear wheels of the car drive out of the garage, the movable plate is not subjected to downward force. During the process of the lifting structure driving the movable plate upward, the locking structure is rendered ineffective, and the movable plate returns to its initial state to prepare for the next car to pass. During the movement of the car, the cooperation between the buffer structure, locking structure and lifting structure causes the movable plate to swing with the first support rod and the second support rod as fulcrums, forming a shock absorption system. This reduces the impact of the car on the passageway plate during the exit of the garage, thereby improving the service life of the passageway plate.

[0013] (2) The double-track pit-type mechanical parking equipment that can ensure the passage of the front train, when the entire car is on the movable plate, forms two fulcrums by having the two adapter grooves on the bottom side of the movable plate contact the first support rod and the second support rod respectively, thereby strengthening the overall force of the movable plate and improving the stability during the passage of the train.

[0014] (3) The double-track pit-type mechanical parking equipment that can ensure the passage of the front train, when the movable plate is moved to the top by the lifting structure, the lateral movement of the movable plate is constrained by the cooperation between the first compression spring, the third guide hole, the connecting rope and the constraint column. When the movable plate is subjected to downward pressure, the lateral swing of the movable plate is constrained by the vertical downward movement of the constraint column inside the third guide hole. This allows the second support rod to accurately enter the interior of the adapter groove under the guidance of the flared opening, thereby improving the stability during use.

[0015] (4) The double-track pit-type mechanical parking equipment that can ensure the passage of the front train can control the operation of the servo motor by means of the signal transmission switch on the double-track mechanical parking device when the passage plate is needed. The servo motor drives the shaft to rotate and release the steel cable wrapped on the shaft. The first compression spring squeezes the movable plate to move upward. When it is necessary to store it, the servo motor is controlled to move in the opposite direction by means of the signal transmission switch on the double-track mechanical parking device so that the steel cable is wound around the shaft again. The steel cable pulls the movable plate downward to store it, so that the passage plate can be moved to the bottom of the car platform for storage again. Attached Figure Description

The end of the steel cable 187 away from the shaft 183 is fixedly connected to the bottom side of the first mounting groove 8. The shaft 183 is rotated to make the steel cable 187 wrap around the shaft 183 to reduce the length of the steel cable 187 outside, pulling the movable plate 6 downward. Two first grooves 14 are symmetrically opened on the upper side of the transverse plate 5. A first compression spring 15 is fixedly connected inside the first groove 14. The upper end of the first compression spring 15 is fixedly connected to the bottom side of the movable plate 6. When the movable plate 6 moves downward, the first compression spring 15 exerts an upward compressive force on the movable plate 6.

[0040] like Figures 4-7 As shown, a second mounting groove 9 is provided on the upper side of the transverse plate 5 near the front end. A buffer structure is provided inside the second mounting groove 9.

[0041] Two first guide holes 165 are symmetrically opened on the upper side of the buffer frame 161. The two first guide holes 165 are symmetrically opened on both sides of the ball screw 164. A second compression spring 166 is fixedly connected to the bottom side of the pressure plate 167 corresponding to the position of the first guide hole 165. When the pressure plate 167 moves downward, the second compression spring 166 always pushes the pressure plate 167 upward. The end of the second compression spring 166 away from the pressure plate 167 is fixedly connected to the bottom side of the second mounting groove 9. Two second guide holes 168 are symmetrically opened on the upper side of the buffer frame 161. A first guide rod 169 is fixedly connected to the bottom side of the pressure plate 167 corresponding to the position of the second guide hole 168.

[0042] like Figures 5-10 As shown, a third mounting groove 10 is provided at the rear upper side of the transverse plate 5. A locking structure is provided inside the third mounting groove 10. The locking structure includes a movable block 174 movably installed inside the third mounting groove 10. A support block 173 that can squeeze the movable block 174 is fixedly connected to the bottom side of the movable plate 6 corresponding to the position of the movable block 174. A damper 175 is fixedly connected at equal intervals to the side of the movable block 174. A squeezing block 177 is fixedly connected to the output end of the damper 175. A second adapter cavity 179 is provided on the side of the third mounting groove 10 corresponding to the position of the squeezing block 177. A first adapter cavity 178 is provided on the side of the squeezing block 177 corresponding to the second adapter cavity 179. A connecting block 171 is fixedly connected to the bottom side of the movable plate 6. A connecting post 172 that is adapted to the first adapter cavity 178 and the second adapter cavity 179 is fixedly connected to the bottom side of the connecting block 171.

[0043] A first guide block 1710 is fixedly connected to the upper side of the extrusion block 177. A second guide block 1711 is fixedly connected to the upper side of the transverse plate 5 at the position corresponding to the first guide block 1710. Slide grooves 1712 are provided on both sides of the third mounting groove 10. A slider 1713 that can slide inside the slide groove 1712 is fixedly connected to the side of the extrusion block 177 at the position corresponding to the slide groove 1712. A return spring 1715 is fixedly connected to the side of the slider 1713. A circular groove is provided on the side of the slide groove 1712 at the position corresponding to the slider 1713.

One end of the second guide rod 1714 is fixedly connected to the side of the slider 1713, and the second guide rod 1714 is located inside the return spring 1715.

[0044] like Figure 5 and Figure 11As shown, the bottom side of the movable plate 6 has two adapter slots 11. The transverse plate 5 is fixedly connected with a first support rod 12 and a second support rod 13 of different heights at the positions corresponding to the two adapter slots 11. The movable plate 6 can swing about the first support rod 12 and the second support rod 13 as rotation centers through the two adapter slots 11.

[0045] The bottom side of the movable plate 6 is provided with flared openings 191 corresponding to the positions of the two adapter slots 11. The upper sides of the first support rod 12 and the second support rod 13 are provided with third guide holes 193 at equal intervals.

The bottom sides of the first support rod 12 and the second support rod 13 are fixedly connected with third support rods 195 at equal intervals.

[0046] Working principle of the invention:

[0047] When a car on the upper parking level away from the ground needs to be retrieved, the car carrier plate 3 of the opposite middle parking level is moved laterally, leaving the area below the upper parking level empty. The car on the upper parking level is then moved downwards into the empty space. The aisle plate 4 is then moved laterally in front of the car. The lifting structure moves the movable plate 6 upwards, driving the car out of the parking space. Initially, the height of the guide plate 7 near the car is flush with the height of the car carrier plate 3. As the car moves, the front wheels move above the guide plate 7, and the buffer structure slows the downward movement of the movable plate 6. When the front wheels reach the position of the first support rod 12, the car's weight causes the first support rod 12 to engage with the adapter groove 11. The car continues to move, and the front of the car passes the first support rod 12. The movable plate 6 swings around the first support rod 12 as the swing center, causing one end of the movable plate 6 located on the guide plate 7 to swing upward. At this time, the rear wheels of the car move onto the guide plate 7, and the car continues to move. The movable plate 6 is subjected to the weight of the car, causing the two fitting slots 11 on the movable plate 6 to fit into the first support rod 12 and the second support rod 13 respectively. When the front of the car passes the second support rod 13, the overall center of gravity of the car is at the position of the front of the car, causing the movable plate 6 to swing around the second support rod 13 as the rotation center. The end of the movable plate 6 away from the guide plate 7 is fixed by a locking structure. At this time, the side of the movable plate 6 closest to the ground is flush with the ground. The front wheels of the car drive out of the garage through the movable plate 6. When the rear wheels of the car drive out of the garage, the movable plate 6 is not subjected to a downward force, and the device returns to its initial state.

[0048] like Figure 13As shown, the transverse plate 5 and the movable plate 6 are located at the bottom of the vehicle platform 3. When needed, the transverse plate 5 is moved to a suitable position, and the servo motor 181 is started. The servo motor 181 begins to rotate counterclockwise to loosen the steel cable 187 wound on the shaft 183. At this time, the first compression spring 15 relaxes and pushes the movable plate 6 upward, moving it to the desired position. Figure 14 When the guide plate 7 stops moving at its position, the edge of the guide plate 7 near the vehicle plate 3 is at the same height as the vehicle plate 3, and the bottom side of the movable plate 6 contacts the top side of the pressure plate 167.

[0049] like Figure 15 As shown, when the front wheels of the vehicle move above the guide plate 7, the guide plate 7 drives the movable plate 6 to move downward. The movable plate 6 presses the pressure plate 167, and the pressure plate 167 presses the ball screw 164. The ball screw 164 rotates and moves downward inside the ball nut 163, thereby slowing down the downward movement of the vehicle. When the front wheels of the vehicle move to the position of the first support rod 12, the movable plate 6 will contact the first support rod 12 with the adapter groove 11.

[0050] like Figure 16 As shown, when the front wheels of the vehicle pass the first support rod 12 and continue to move, the movable plate 6 will swing around the first support rod 12 as the rotation center. At this time, one end of the guide plate 7 on the movable plate 6 begins to move upward until it moves to the same height as the vehicle platform 3. Then the rear wheels of the vehicle move onto the guide plate 7. As the vehicle continues to move, the second support rod 13 and the corresponding adapter groove 11 will come into contact, so that the bottom side of the movable plate 6 has two fulcrums, and the vehicle can continue to move on the movable plate 6.

[0051] like Figure 17As shown, when the front wheels of the car pass the second support rod 13, the car continues to move. Because the engine is located at the front, the car's center of gravity is at the front. The movable plate 6 swings around the second support rod 13, causing the movable plate 6 to move downwards along with the connecting block 171. The connecting block 171 then moves downwards along with the connecting column 172. Under the swinging motion of the movable plate 6, the movable plate 6, along with the support pressure block 1733, presses against the side of the movable block 174. As the car continues to move, with the increase in gravity, the connecting column 172 moves downwards between the first guide block 1710 and the second guide block 1711. The connecting column 172 presses against the first guide block 1710, causing the first guide block 1710 to move the pressing block 177 towards one side of the movable block 174, until the connecting column 172 is pressed into the interior of the first adapter cavity 178 and the second adapter cavity 179. At this point, the movable plate 6 moves away from the guide plate 7. One side of the upper edge is flush with the ground, allowing the front wheels of the vehicle to move off the movable plate 6. As the front wheels of the movable plate 6 move off, the rear wheels of the movable plate 6 pass over the second support rod 13 and continue to move forward. At this time, the position of the movable plate 6 remains unchanged until the rear wheels of the vehicle leave the movable plate 6. The downward pressure of the movable plate 6 disappears, and the first compression spring 15 drives the movable plate 6 to move upward as a whole. The movable plate 6, along with the support block 1733, separates from the movable block 174. First, the damper 175 loses pressure and begins to reset. The damper 175 slides against the movable block 174 inside the third mounting groove 10. The reset spring 1715 pulls the slider 1713, and the slider 1713 moves the movable block 174 inside the third mounting groove 10, creating a gap between the compression block 177 and the third mounting groove 10, causing the connecting column 172 to move upward. At this time, the device returns to its initial position.
