Description

Technical Field

[0001] The present invention relates to the field of vehicle parking assistance systems, and in particular to a parking assistance system. Background Art

[0002] As the number of vehicles increases, parking spaces in parking lots become increasingly tight, resulting in smaller intervals between adjacent parking spaces in many garages. This makes it difficult for drivers to park their vehicles safely and quickly if they are not proficient in parking techniques, and it can easily cause congestion when there are many vehicles.

[0003] The main principle of the parking assistance system in the prior art is to help the driver park the vehicle in the parking space by guiding the driver or planning the route. Although this reduces the difficulty of parking to a certain extent, the driver still needs to spend a lot of energy to park the vehicle. Moreover, for drivers with less technical skills, this assistance method still does not provide effective help. For this reason, this solution proposes a parking assistance system. Summary of the invention

The spring is located at the top of the movable block, and the bottom of the spring is fixedly connected to the movable block, and the top of the spring is fixedly connected to the top of the sliding groove.

[0016] Through the above technical solution, not only can the linkage rack be moved along the telescopic direction of the telescopic member, but the linkage rack can also automatically descend and return to its original position after the pressure is lost.

[0043] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0044] Embodiment 1:

[0045] Please combine Figure 1 - Figure 7 , a parking assistance system of this embodiment includes:

[0046] The lifting mechanism includes a base 1, a turntable 32 rotatably connected to the top of the base 1, a telescopic member 2 installed on the top of the turntable 32 and a fixed plate 3 installed at the output end of the telescopic member 2. Receiving holes are provided at both ends of the fixed plate 3. Movable plates 4 are installed in the two receiving holes. The outer periphery of the movable plate 4 is consistent with the receiving holes, so as to avoid the movable plate 4 from shaking when moving. The telescopic member 2 adopts a hydraulic cylinder. After the vehicle drives to the top of the lifting mechanism and stops, the telescopic member 2 is extended, and the movable plate 2 is extended outward at the same time, so that one end of the movable plate 2 extends to the outside of the chassis of the car, so that the movable plate 2 can be used to lift the car upward after the fixed plate 3 is raised.

[0047] The steering mechanism includes a transmission ring gear 15 fixed on the top of the turntable 32 and a transmission motor 16 installed on the top of the base 1 for driving the transmission ring gear 15 to rotate. The output shaft of the transmission motor 16 is sleeved with a steering gear meshing with the transmission ring gear 15. After the car is lifted, the transmission motor 16 can be started. After the transmission motor 16 rotates, it drives the transmission ring gear 15 to rotate. The transmission ring gear 15 then drives the turntable 32 to rotate. After the turntable 32 rotates, it drives the telescopic member 2 to rotate synchronously, so that the lifted car can be turned around and parked in the parking space faster.

[0048] The driving mechanism is set to two and is used to drive the two movable plates 4 to move along the length direction of the storage hole. The driving mechanism includes a linkage screw 7 rotatably connected to the outer periphery of the fixed end of the telescopic member 2, a moving block 10 threadedly sleeved on the outer periphery of the linkage screw 7, a telescopic rod fixed to the top of the moving block 10, a linkage gear 25 sleeved on the outer periphery of the linkage screw 7, and a linkage rack 22 installed on the outer periphery of the fixed end of the telescopic member 2 through an elastic member. The telescopic rod includes a storage tube 9 fixed to the top of the moving block 10 and a movable rod 8 movably sleeved in the storage tube 9. The top of the movable rod 8 passes through a connecting groove 24 and is fixedly connected to the bottom surface of the movable plate 4. The bottom of the storage hole is provided with a connecting groove 24 arranged along its length direction. The top of the telescopic rod The linkage rack 22 passes through the connecting groove 24 and is fixedly connected to the bottom surface of the movable plate 4. The linkage rack 22 is meshed with the linkage gear 25. When the linkage rack 22 rises, it will drive the linkage screw 7 to rotate forward, thereby driving the moving block 10 to move to the side away from the telescopic member 2, and then driving the movable plate 3 to extend to the outside of the storage hole. On the contrary, when the linkage rack 22 descends, it will drive the linkage screw 7 to reverse, thereby driving the moving block 10 to approach the side of the telescopic member 2, and also driving the movable plate 3 to move toward the inside of the storage hole. The setting of the telescopic rod can make the length of the telescopic rod adaptively adjusted when the fixed plate 2 is lifted or lowered. When the fixed plate 2 rises, the movable rod 8 extends upward, and when the fixed plate 2 descends, the movable rod 8 shrinks toward the inside of the storage tube 9.

[0049] The elastic member includes a mounting plate 19 fixed to the outer periphery of the telescopic member 2 and a connecting member movably mounted on a long side of the mounting plate 19 facing the linkage rack 22. A slide groove 29 arranged along the telescopic direction of the telescopic member 2 is opened on the long side of the mounting plate 19 facing the linkage rack 22. The connecting member includes a sleeve rod 30 fixed in the slide groove 29, a movable block 28 movably sleeved on the outer periphery of the sleeve rod 30, and a spring. One end of the movable block 28 is fixedly connected to the outer wall of the linkage rack 22, the spring is located at the top of the movable block 28, and the bottom of the spring is fixedly connected to the movable block 28, and the top of the spring is fixedly connected to the top of the slide groove 29. When the linkage rack 22 is squeezed upward and rises, the movable block 28 moves upward along the slide groove, and the spring is compressed accordingly. Conversely, when the linkage rack 22 loses the upward squeezing, it can automatically move downward under the action of the spring and return to its original position.

[0050] The lifting mechanism includes a driving ring 17 rotatably connected to the top of the turntable 32 and a lifting component installed on the driving ring 17 and used to drive the linkage rack 22 to rise when the driving ring 17 rotates. The lifting component includes an active gear ring 33 sleeved on the inner ring of the driving ring 17 and two abutment blocks 18 fixed on the top surface of the driving ring 17. The driving ring 17 is located at the inner ring of the transmission gear ring 15, and the driving ring 17 is coaxially arranged with the transmission gear ring 15. The two abutment blocks 18 are both arc-shaped blocks, and the top surface of the abutment blocks 18 is parallel to the top surface of the driving ring 17, and the two sides of the abutment blocks 18 are inclined, and the inclination angles are the same. The top surface length of the abutment blocks 18 is less than the bottom surface length thereof. The linkage rack 22 cooperates with the abutment blocks 18, and a ball is installed at the bottom of the linkage rack 22. When the movable plate 4 is stored in the storage hole, the linkage The ball at the bottom of the rack 22 abuts against the top of the drive ring 17. As the drive ring 17 rotates forward, the abutment block 18 rotates synchronously with the drive ring 17. When the ball at the bottom of the linkage rack 22 contacts the abutment block 18, it will move up along the inclined surface of the abutment block 18 during the continued rotation of the drive ring 17, thereby gradually lifting the linkage rack 22 upward until the linkage rack 22 moves to the top surface of the abutment block 18. The height of the linkage rack 22 is not affected by the rotation of the drive ring 17 and remains unchanged. After the linkage rack 22 moves up, it will drive the linkage screw 22 to rotate forward, thereby extending the movable plate 4 outward. Conversely, when the drive ring 7 is reversed, the linkage rack 22 will gradually slide down along the inclined surface of the abutment block 18 under the action of the spring until it abuts against the top surface of the drive ring 17, thereby driving the movable plate 4 to be re-stored into the storage hole.

[0051] A linkage mechanism is installed on the periphery of the fixed end of the telescopic member 2 and is used to drive the driving ring 17 to rotate when the fixed plate 3 is lifted or lowered. The linkage mechanism includes a rotating shaft rotatably connected to the periphery of the fixed end of the telescopic member 2, a driving gear 31 and an active gear 20 sleeved on the periphery of the rotating shaft, and an active rack 21 fixed to the bottom surface of the fixed plate 3. The active rack 21 is meshed with the driving gear 31, and the active gear 20 is meshed with the active gear ring 33. The driving ring 17 and the active gear ring 33 are both coaxially arranged with the telescopic member 2, and a gap is provided between the inner ring of the active gear ring 33 and the periphery of the telescopic member 2. The setting of the gap makes it possible for the lifting and lowering of the active rack 21 to not be blocked by the active gear ring 33, and the setting of the linkage mechanism makes it possible for the telescopic member 2 to extend and drive the fixed plate 2 to rise while the fixed plate 2 rises. , it will drive the active rack 21 to move up synchronously. After the active rack 21 moves up, it will drive the driving gear 31 to rotate. The driving gear 31 will then drive the rotating shaft to rotate, and the rotating shaft will then drive the active gear 20 to rotate. The active gear 20 will finally drive the active gear ring 33 to rotate forward, so that the driving ring 17 will rotate forward synchronously. When the abutment block 18 contacts the linkage rack 22, it will lift it upward, so that the movable plate 4 can be automatically pulled out during the rising process of the fixed plate 2. Conversely, when the telescopic member 2 contracts and drives the fixed plate 2 to descend, it can drive the driving ring 17 to reverse at the same time, and the linkage rack 22 will also gradually move downward along the inclined surface of the abutment block 18 under the action of the spring, so that the movable plate 2 is automatically stored in the storage hole during the descent of the fixed plate 2.

[0052] The implementation principle of this embodiment is as follows: during installation, a foundation pit is dug at the bottom of the parking lot so that the top surface of the fixed plate is flush with the bottom surface. When parking, the vehicle is driven to the top of the lifting mechanism and then stops. Then the telescopic member 2 is started to extend. The extension of the telescopic member 2 drives the fixed plate 2 to move up. While the fixed plate 2 moves up, the active rack 21 is driven to move up synchronously. After the active rack 21 moves up, it drives the rotating shaft to rotate forward. The rotating shaft then drives the active gear 20 to rotate forward. The active gear 20 finally drives the active gear ring 33 to rotate forward, so that the driving ring 17 rotates forward synchronously. After the driving ring 17 rotates forward, it drives the abutment block 18 to approach the linkage rack 22. When the ball at the bottom of the linkage rack 22 contacts the abutment block 18, it will move up along the inclined surface of the abutment block 18 during the continued rotation of the driving ring 17, thereby gradually lifting the linkage rack 22 upward. After the linkage rack 22 moves up, it drives the linkage screw 22 to rotate forward. After the linkage screw 22 rotates forward, it drives the moving block 10 to move to the side away from the telescopic member 2, and then drives the movable plate 3 to extend outward from the storage hole, and then the movable plate 4 can be extended outward, so that one end of the movable plate 2 extends to the outside of the car chassis, until the linkage rack 22 moves to the top surface of the abutment block 18, the height of the linkage rack 22 is not affected by the rotation of the drive ring 17 and remains unchanged, so that the movable plate 2 can be used to lift the car upward after the fixed plate 3 continues to rise, and after the car is lifted off the ground, the transmission motor 16 is started to rotate, and the transmission motor 16 rotates and drives the transmission gear ring 15 to rotate, and the transmission gear ring 15 drives the turntable 32 to rotate, and the turntable 32 rotates and drives the telescopic member 2 to rotate synchronously, so that the lifted car can be turned, until the vehicle can directly drive into the parking space in a straight line, the direction can be stopped, and then the telescopic member 2 can be started to contract and the car can be gradually put down;

[0053] When the telescopic member 2 contracts and drives the fixed plate 2 to descend, the active rack 21 descends accordingly, thereby driving the rotating shaft to reverse, and the rotating shaft then drives the driving ring 7 to reverse. After the driving ring 7 reverses, it drives the abutment block 18 to flip synchronously, so that the linkage rack 22 gradually slides down along the inclined surface of the abutment block 18 under the action of the spring. After the linkage rack 17 moves down, it drives the linkage screw 22 to reverse, so that the moving block 10 moves to the side close to the telescopic member 2, and then can drive the movable plate 4 to retract toward the inside of the storage hole, until it abuts against the top surface of the driving ring 17, and the movable plate 4 is re-stored into the storage hole.

[0054] Embodiment 2:

[0055] Combination Figure 1 and Figure 3 - Figure 5 Based on the embodiment 1, the present embodiment is further improved in that: a cushion block 5 is installed on the top surface of the movable plate 4, and the cushion block 5 is made of rubber.

[0056] The implementation principle of this embodiment is: the setting of the pad 5 can prevent the movable plate 4 from directly and rigidly contacting the edge of the chassis of the vehicle, thereby effectively avoiding the wear of the chassis of the vehicle.

[0057] Embodiment 3:

[0058] Combination Figure 1 - Figure 5 The present embodiment is further improved on the basis of the embodiment 1 in that: the top surfaces of the two movable plates 4 are provided with mounting holes for mounting the cushion blocks 5, the bottoms of the two mounting holes are provided with air bags 26, the cushion blocks 5 are movably mounted in the mounting holes, and the bottoms of the mounting blocks are fixedly connected to the top surfaces of the air bags 26, the outer periphery of the cushion blocks 5 is consistent with the mounting holes, and the base 1 is provided with two air delivery mechanisms for pumping and releasing air from the air bags 26 when the transmission gear ring 15 rotates, the air delivery mechanisms include an air cylinder 11 mounted on the top of the base 1, a piston plate 27 mounted in the air cylinder 11, and a transmission member mounted on the top of the base 1 for driving the piston plate 27 to move along the axial direction of the air cylinder 11 when the transmission gear ring 15 rotates, the air cylinder 11 is directly opposite to one side of the transmission gear ring 15 An opening is provided on the side, and an adjusting tube 23 and an air guide tube 6 are installed at the other end of the air cylinder 11. The other end of the air guide tube 6 extends into the mounting hole and is connected to the air bag 26. A valve is installed on the adjusting tube 23. When the valve is opened, outside air can be sucked in through the adjusting tube 23, so that the air leaked in the air bag 26 or the air cylinder 11 can be supplemented. After closing the valve, when the piston plate 27 moves to the side close to the air guide tube 6, the air in the air cylinder 11 can be pressed into the air bag 26, so that the air bag 26 expands, and the cushion block 5 will also move up and gradually extend to the outside of the mounting hole. Conversely, after the piston plate 27 moves to the side away from the air guide tube 6, the air in the air bag 26 can be drawn back, and the cushion block 5 will also drop accordingly.

[0059] The transmission member includes a transmission screw 13 rotatably connected to the top surface of the base 1, a screw sleeve 12 threadedly sleeved on the outer periphery of one end of the transmission screw 13, and a transmission gear 14 fixed to the other end of the transmission screw 13. The outer periphery of the drive ring 17 is sleeved with a fixed gear ring 34, and the transmission gear 14 is meshed with the fixed gear ring 34. One end of the screw sleeve 12 is fixedly connected to the outer wall of the piston plate 27 close to the opening of the air cylinder 11. The drive ring 17 will drive the fixed gear ring 34 to rotate synchronously when it rotates, and the fixed gear ring 34 can drive the transmission screw 13 to rotate after it rotates. The transmission screw 13 rotates in different directions, which can drive the screw sleeve 12 to move in different directions, thereby achieving the purpose of driving the piston plate 27 to move while the drive ring 17 rotates.

[0060] The implementation principle of this embodiment is as follows: when the driving ring 17 rotates forward, it will drive the fixed gear ring 34 to rotate forward synchronously. After the fixed gear ring 34 rotates forward, it will drive the transmission screw 13 to rotate forward. After the transmission screw 13 rotates forward, it will drive the screw sleeve 12 and the piston plate 27 to move to the side close to the air guide pipe 6, so that the air in the air cylinder 11 can be pressed into the air bag 26. After the air bag 26 is filled with air, it expands, and then it can drive the cushion block 5 to move upward and gradually extend out of the mounting hole, thereby achieving the purpose of automatically pushing the cushion block 5 upward in the process of the movable plate 4 extending outward. On the contrary, when the driving ring 17 is reversed, it will drive the transmission screw 13 to rotate backward, and the screw sleeve 12 will also drive the piston plate 27 to move to the side away from the air guide pipe 6, so that the air in the air bag 26 is drawn back into the air cylinder 11, and the air bag 26 shrinks accordingly, so that the cushion block 5 can be driven to move downward and gradually be received inside the receiving hole.
