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 gradually increases, parking spaces in parking lots are becoming increasingly tight, resulting in smaller distances 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 existing technology 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 relatively novice skills, this assistance method still does not provide effective help. For this reason, this solution proposes a parking assistance system. Summary of the Invention

[0004] The present invention provides a parking assistance system that solves the problem in the prior art of parking difficulties caused by drivers' lack of parking skills.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A parking assistance system comprising:

[0007] The lifting mechanism includes a base, a turntable rotatably connected to the top of the base, a telescopic member installed on the top of the turntable, and a fixed plate installed at the output end of the telescopic member. Both ends of the fixed plate are provided with receiving holes, and movable plates are installed in the two receiving holes.

[0008] The steering mechanism includes a transmission gear ring fixed to the top of the turntable and a transmission motor installed on the top of the base for driving the transmission gear ring to rotate;

[0009] The driving mechanism is provided with two and is respectively used to drive the two movable plates to move along the length direction of the storage hole. The driving mechanism includes a linkage screw rotatably connected to the outer periphery of the fixed end of the telescopic member, a moving block threadedly sleeved on the outer periphery of the linkage screw, a telescopic rod fixed on the top of the moving block, a linkage gear sleeved on the outer periphery of the linkage screw, and a linkage rack installed on the outer periphery of the fixed end of the telescopic member through an elastic member. The bottom of the storage hole is provided with a connecting groove arranged along the length direction thereof. The top of the telescopic rod passes through the connecting groove and is fixedly connected to the bottom surface of the movable plate. The linkage rack is meshed with the linkage gear.

[0010] A lifting mechanism comprising a driving ring rotatably connected to the top of the turntable and a lifting assembly mounted on the driving ring and used to drive the linkage rack to rise when the driving ring rotates;

[0011] The linkage mechanism is installed on the outer periphery of the fixed end of the telescopic member and is used to drive the driving ring to rotate when the fixed plate is raised or lowered.

[0012] Through the above technical solution, when parking, the vehicle can be lifted up and then turned around, so that the vehicle can directly enter the parking space in a straight line, thereby greatly reducing the time and difficulty of parking and avoiding vehicle scratches due to unskilled parking.

[0013] As a further improvement of the above solution, the telescopic rod includes a storage tube fixed on the top of the moving block and a movable rod movably sleeved in the storage tube, and the top of the movable rod passes through the connecting groove and is fixed to the bottom surface of the movable plate.

[0014] The above technical solution can prevent the lifting and lowering of the fixed plate from pulling the movable block.

[0015] As a further improvement of the above scheme, the elastic part includes a mounting plate fixed to the outer periphery of the telescopic part and a connecting part movably mounted on the long side of the mounting plate facing the linkage rack. The long side of the mounting plate facing the linkage rack is provided with a sliding groove arranged along the telescopic direction of the telescopic part. The connecting part includes a sleeve rod fixed in the sliding groove, a movable block movably sleeved on the outer periphery of the sleeve rod and a spring. One end of the movable block is fixed to the outer wall of the linkage rack. The spring is located at the top of the movable block, and the bottom of the spring is fixed to the movable block, and the top of the spring is fixed 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.

[0017] As a further improvement of the above scheme, the lifting assembly includes an active gear ring sleeved on the inner ring of the driving ring and two abutment blocks fixed on the top surface of the driving ring. The driving ring is located on the inner ring of the transmission gear ring, and the driving ring and the transmission gear ring are coaxially arranged. The two abutment blocks are both arc-shaped blocks, and the top surface of the abutment block is parallel to the top surface of the driving ring, and both sides of the abutment block are inclined, and the inclination angle is the same. The top surface length of the abutment block is smaller than the bottom surface length, and the linkage rack cooperates with the abutment block.

[0018] Through the above technical solution, the linkage rack is gradually lifted upward by the movement of the abutment block, thereby driving the linkage screw to rotate.

[0019] As a further improvement of the above solution, the driving ring and the active gear ring are both coaxially arranged with the telescopic member, and a gap is provided between the inner ring of the active gear ring and the outer periphery of the telescopic member.

[0020] Through the above technical solution, the driving ring and the active ring gear can rotate synchronously, and the active ring gear will not affect the lifting and lowering of the active rack.

[0021] As a further improvement of the above scheme, the linkage mechanism includes a rotating shaft rotatably connected to the outer periphery of the fixed end of the telescopic member, a driving gear and an active gear sleeved on the outer periphery of the rotating shaft, and an active rack fixed to the bottom surface of the fixed plate, the active rack is engaged with the driving gear, and the active gear is engaged with the active ring gear.

[0022] Through the above technical solution, the driving gear can be driven to rotate simultaneously when the fixed plate is raised or lowered.

[0023] As a further improvement of the above solution, a pad is installed on the top surface of the movable plate, and the pad is made of rubber.

[0024] With the above technical solution, direct hard contact between the vehicle chassis and the movable panel can be avoided by the pad.

[0025] As a further improvement of the above scheme, the top surfaces of the two movable plates are provided with mounting holes for installing gaskets, and airbags are installed at the bottom of the two mounting holes. The gaskets are movably installed in the mounting holes, and the bottom of the mounting blocks are fixedly connected to the top surface of the airbags. The outer periphery of the gaskets is consistent with the mounting holes, and two air supply mechanisms are installed on the base for pumping and deflating air in the airbags when the transmission ring gear rotates.

[0026] With the above technical solution, the air cylinder is used to pump and release air into the airbag, thereby driving the cushion block to rise or fall.

[0027] As a further improvement of the above scheme, the air delivery mechanism includes an air cylinder installed on the top of the base, a piston plate installed in the air cylinder, and a transmission member installed on the top of the base for driving the piston plate to move along the axial direction of the air cylinder when the transmission ring gear rotates. The air cylinder is provided with an opening on the side facing the transmission ring gear, and an adjusting tube and an air guide tube are installed at the other end of the air cylinder. The other end of the air guide tube extends into the mounting hole and is connected to the airbag, and a valve is installed on the adjusting tube.

[0028] Through the above technical solution, the air in the air cylinder is pressed into the air bag or the air in the air bag is sucked back into the air cylinder by driving the movement of the piston plate.

[0029] As a further improvement of the above scheme, the transmission member includes a transmission screw rotatably connected to the top surface of the base, a screw sleeve threadedly sleeved on the outer periphery of one end of the transmission screw and a transmission gear fixed to the other end of the transmission screw, the outer periphery of the drive ring is sleeved with a fixed gear ring, the transmission gear is meshed with the fixed gear ring, and one end of the screw sleeve is fixedly connected to the outer wall of the piston plate on one side close to the opening of the cylinder.

[0030] Through the above technical solution, the driving screw can be driven to rotate while the driving ring rotates, thereby driving the piston plate to move accordingly.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. Through the cooperation among the lifting mechanism, steering mechanism, driving mechanism, jacking mechanism and linkage mechanism, the two movable plates can be driven to extend outward while the fixed plate rises, and after extending to a certain length, they will not continue to extend with the rise of the fixed plate, but remain stationary. Then, the car can be lifted up while the fixed plate continues to rise, and then the direction of the car can be turned by cooperating with the steering mechanism, avoiding the trouble of the driver who is not proficient in parking and steering.

[0033] 2. Through the cooperation between the air supply mechanism and the fixed gear ring, air can be inflated into the airbag during the forward rotation of the fixed gear ring, so that the cushion block is pushed upward to avoid direct hard contact between the vehicle chassis and the movable plate. After the fixed gear ring is reversed, the air in the airbag can be pumped out, thereby retracting the cushion block into the mounting hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The present invention will be 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 new embodiments.

[0044] Example 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, and movable plates 4 are installed in the two receiving holes. The outer periphery of the movable plate 4 coincides with the receiving holes, thereby preventing 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 extends and the movable plate 2 extends outward at the same time, so that one end of the movable plate 2 extends to the outside of the car chassis, 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 to 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 that meshes 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, and 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 direction of the lifted car can be turned, so that it can be parked in the parking space faster.

[0048] The driving mechanism is provided with two, and is used to drive the two movable plates 4 to move along the length direction of the storage hole respectively. 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 on 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 the connecting groove 24 and is fixed 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 move closer to the side of the telescopic member 2, and thus driving the movable plate 3 to move toward the inside of the storage hole. The arrangement of the telescopic rod allows the length of the telescopic rod to be 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 contracts 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 one long side of the mounting plate 19 facing the linkage rack 22. The mounting plate 19 is provided with a slide groove 29 arranged along the extension and contraction direction of the telescopic member 2 on one long side 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 fixed 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 fixed to the movable block 28, and the top of the spring is fixed 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 its 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 have the same inclination angle. The top surface length of the abutment blocks 18 is smaller than the bottom surface length. The linkage rack 22 cooperates with the abutment blocks 18. A ball bearing is installed at the bottom of the linkage rack 22. When the movable plate 4 is received in the receiving hole, the linkage On the contrary, when the driving 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 driving ring 17, thereby driving the movable plate 4 to be re-stored into the storage hole.

[0051] The linkage mechanism is installed on the periphery of the fixed end of the telescopic member 2 and is used to drive the drive ring 17 to rotate when the fixed plate 3 is lifted. 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 a driving 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 engaged with the driving gear 31, and the active gear 20 is engaged with the active ring gear 33. The drive ring 17 and the active ring gear 33 are both coaxially arranged with the telescopic member 2, and a gap is provided between the inner ring of the active ring gear 33 and the periphery of the telescopic member 2. The setting of the gap makes it possible for the lifting of the active rack 21 to not be blocked by the active ring gear 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 at the same time. , 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 outward 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 can be automatically stored inside the storage hole during the descending process of the fixed plate 2.

[0052] When the vehicle is parked, the vehicle is driven to the top of the lifting mechanism and stops, and then the telescopic member 2 is started to extend, and the telescopic member 2 extends to drive the fixed plate 2 to move up, and the fixed plate 2 moves up while driving the active rack 21 to move up synchronously, and after the active rack 21 moves up, it drives the rotating shaft to rotate forward, and the rotating shaft drives the active gear 20 to rotate forward, and the active gear 20 finally drives the active gear ring 33 to rotate forward, so that the driving ring 17 rotates forward synchronously, and the driving ring 17 drives the abutment block 18 to approach the linkage rack 22 after the driving ring 17 rotates forward. When the ball bearing 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, and 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, thereby driving the movable plate 3 to extend outside the storage hole and then the movable plate 4 to extend 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. After the bicycle is lifted off the ground, the transmission motor 16 is started to rotate. After the transmission motor 16 rotates, it drives the transmission ring gear 15 to rotate, and the transmission ring gear 15 drives the turntable 32 to rotate. After the turntable 32 rotates, it drives the telescopic member 2 to rotate synchronously, so that the direction of the lifted car can be turned. The direction can be stopped after the vehicle can be driven directly into the parking space. After that, the telescopic member 2 can be started to retract and the car can be gradually lowered.

[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 drives 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] Example 2:

[0055] Combine Figure 1 and Figure 3 - Figure 5 Based on Example 1, this embodiment is further improved in that: a pad 5 is installed on the top surface of the movable plate 4, and the pad 5 is made of rubber.

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

[0057] Example 3:

[0058] Combine Figure 1 - Figure 5 , based on Example 1, this embodiment is further improved in that: the top surfaces of the two movable plates 4 are provided with mounting holes for mounting the cushion blocks 5, and the bottoms of the two mounting holes are installed with air bags 26, the cushion blocks 5 are movably installed 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 coincides with the mounting holes, and two air delivery mechanisms are installed on the base 1 for pumping and degassing the air bags 26 when the transmission gear ring 15 rotates, the air delivery mechanism includes an air cylinder 11 installed on the top of the base 1, a piston plate 27 installed in the air cylinder 11, and a transmission member installed 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 There is an opening on the side, and the other end of the air cylinder 11 is equipped with a regulating tube 23 and an air guide tube 6. 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 regulating tube 23. When the valve is opened, outside air can be sucked in through the regulating tube 23, so that the air leaked in the air bag 26 or the air cylinder 11 can be replenished. 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.

[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 engaged 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. When the drive ring 17 rotates, it will drive the fixed gear ring 34 to rotate synchronously. After the fixed gear ring 34 rotates, it can drive the transmission screw 13 to rotate. When the transmission screw 13 rotates in different directions, it 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] When the driving ring 17 rotates forward, it drives the fixed gear ring 34 to rotate forward synchronously. After the fixed gear ring 34 rotates forward, it drives the transmission screw 13 to rotate forward. After the transmission screw 13 rotates forward, it drives the nut 12 and the piston plate 27 to move toward the side close to the air guide tube 6, so that the air in the air cylinder 11 can be pressed into the air bag 26. The air bag 26 expands after being filled with air, and then drives the pad 5 to move upward and gradually extend out of the mounting hole, thereby achieving the purpose of automatically pushing the pad 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 nut 12 will also drive the piston plate 27 to move toward the side away from the air guide tube 6, thereby drawing the air in the air bag 26 back into the air cylinder 11, and the air bag 26 shrinks thereupon, thereby driving the pad 5 to move downward and gradually receive it inside the receiving hole.

[0061] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
