In limited land space, especially in cities, it is increasingly difficult for people to find parking places, which affects people's travel. In view of this, a car tilting parking system is disclosed in the patent document with application number 202220727665.2. The lateral walking wheel A5 of the car tilting parking system in the above-mentioned prior art is driven by a hydraulic motor through the walking wheel transmission shaft A6, and can do forward and reverse movement. It does not have an adjustment function, that is, it will move unsteadily when encountering uneven ground; in addition, the car tilting parking system in the above-mentioned prior art is not provided with a corresponding device for fixing the wheels, and the vehicle will slip when it is raised with the frame.

The parking method can also prevent the vehicle from sliding down when parked on the parking rack.

[0026] Compared with the prior art, the present invention has the following advantages: when the lateral walking mechanism moves laterally, the front floating frame and the rear floating frame can swing along the front floating axis and the rear floating axis respectively (that is, the so-called adjustment function) through the arranged floating assembly to adapt to the uneven ground. When the floating assembly (that is, the front floating assembly and the rear floating assembly) encounters uneven ground, the rollers will automatically adjust to make the surfaces of the front floating wheels and the rear floating wheels fit well with the ground, thereby increasing the friction with the ground, and the walking is powerful, stable and reliable.

[0027] The anti-skid device is installed at the rear of the parking lane. When the rear wheels of the vehicle are reversed onto the load-bearing frame, as the bracket beam rises, the rear wheels of the vehicle will sink into the sunken groove of the load-bearing frame and be blocked by the baffle body to prevent the vehicle from sliding after the rear end is lifted.

[0028] The lower end of the telescopic sleeve in the safety device is movably connected to the hinged seat of the telescopic sleeve and the middle part of the rear cross beam of the parking frame base, and the upper end of the telescopic rod is connected to the bracket beam by a pin. After the upper and lower pins are connected, as the parking lane of the parking frame moves up and down, the telescopic rod extends and shortens along with the parking lane and moves in the telescopic sleeve. During the process of pulling out the telescopic rod, the telescopic rod can be clamped by a ratchet hook so that it can only be pulled out in one direction. When the telescopic rod is retracted, the ratchet hook is controlled by the electromagnetic core so that the ratchet hook is disengaged from the ratchet groove, thereby realizing the retraction of the telescopic rod. The safety device can improve safety performance and prevent the vehicle from falling.

[0029] The outer guide rail in the telescopic guide rail is fixed to the ground, and the inner guide rail is fixed to the transverse base. The parking rack moves by means of walking rollers. During the movement, the moving direction can be limited by the set telescopic guide rail to avoid deviation. The parking and picking up processes (moving out and moving in) are exactly the same. In order to ensure that the queue does not deform or distort and always remains consistent, the telescopic guide rail does not damage the road and ensures that the parking rack can move back and forth on the guide rail track without deviation.

[0030] The space-saving parking rack lifted by the rear of the car is used to park the vehicle. When parking is needed, the parking lane can be moved out of the parking space. After the parking lane is lowered, the vehicle is reversed onto the parking lane. After the parking lane is raised, the parking lane is moved into the parking space. When the vehicle is parked in the parking space, the rear of the vehicle is lifted up along with the parking lane to achieve the purpose of saving space (saving ground space). When parking the vehicle, it is necessary to reverse from the front end of the parking rack to the parking rack, and when taking the vehicle, it is also driven out from the front end of the parking rack.

[0053] The rear floating assembly in this embodiment includes a rear floating frame A26, a rear floating shaft A27, a rear floating wheel A28, a rear transmission tooth A29 and a rear transition tooth A210. The rear floating frame A26 is installed on the rear cross beam A14 through the rear floating shaft A27.

The rear transmission tooth A29 is coaxially arranged with the rear floating wheel A28. The rear transition tooth A210 is installed on the rear floating shaft A27, and the rear transition tooth A210 is meshed with the rear transmission tooth A29.

[0054] In this embodiment, the front driven assembly includes a front driven wheel A31 and a front driven shaft A32, and the front driven wheel A31 is installed on the front cross beam A13 through the front driven shaft A32; the rear driven assembly includes a rear driven wheel A33 and a rear driven shaft A34, and the rear driven wheel A33 is installed on the rear cross beam A14 through the rear driven shaft A34.

[0055] The driving assembly A4 in this embodiment includes a driving motor bracket A41, a driving shaft A42, a driving motor A43 and a driving gear A44.

The output shaft of the driving motor A43 and the driving shaft A42 are transmitted through the driving gear A44, and the two ends of the driving shaft A42 are respectively connected to the front floating wheel A23 and the rear floating wheel A28.

[0056] That is to say, the lateral walking mechanism A is respectively equipped with two floating components A2 (i.e., the front floating component and the rear floating component) and two driven components A3 (i.e., the front driven component and the rear driven component) at the four corners of the lateral moving base A1, wherein the front floating component is composed of two front floating wheels A23 installed on the front floating frame A21, the shaft end of the front floating wheel A23 is equipped with front transmission teeth A24, the two front transmission teeth A24 are meshed with the front transition teeth A25, the front transition teeth A25 are installed on the front floating shaft A22, so that the rolling shafts rotate in the same direction, and the rear floating component is composed of two rear floating wheels A28 installed on the rear floating wheel A28, the shaft end of the rear floating wheel A28 is equipped with rear transmission teeth A29, the two rear transmission teeth A29 are meshed with the rear transition teeth A210, the rear transition teeth A210 are installed on the rear floating shaft A27, so that the rolling shafts rotate in the same direction.

[0057] The shaft ends of one of the front floating wheels A23 and one of the rear floating wheels A28 are connected to the two ends of the driving shaft A42 respectively. The driving shaft A42 and the output shaft of the driving motor A43 are meshed and transmitted with each other through two driving gears A44.

[0058] In order to adapt to the uneven ground, each set of floating components A2 (i.e., the front floating component and the rear floating component) is made into a floating structure. When encountering uneven ground, the rollers will automatically adjust so that the surfaces of the front floating wheels A23 and the rear floating wheels A28 are well matched with the ground, increasing the friction with the ground, making walking powerful, correct and reliable.

[0059] The "floating structure" means that one end of the front floating shaft A22 is installed on the front crossbeam A13, one end of the rear floating shaft A27 is installed on the rear crossbeam A14, a front floating wheel A23 is installed on each side of the front floating frame A21, a rear floating wheel A28 is installed on each side of the rear floating frame A26, the middle of the front floating frame A21 passes through the front floating shaft A22, the middle of the rear floating frame A26 passes through the rear floating shaft A27, and adjustable joint bearings are installed between the front floating frame A21 and the front floating shaft A22, as well as between the rear floating frame A26 and the rear floating shaft A27, so that when the ground is uneven, the two front floating wheels A23 and the two rear floating wheels A28 can change with the unevenness of the ground as the front floating frame A21 and the rear floating frame A26 stick close to the ground.

[0060] The front floating frame A21 and the rear floating frame A26 are respectively installed on the front crossbeam A13 and the rear crossbeam A14, and are located on the right side of the traverse base A1. The two front floating wheels A23 and the two rear floating wheels A28 are on the ground, and the traverse base A1 is between 15-30 mm above the ground. The front driven wheel A31 and the rear driven wheel A33 are respectively installed on the front crossbeam A13 and the rear crossbeam A14, and are located on the left side of the traverse base A1. The front driven wheel A31 and the rear driven wheel A33 are respectively installed on the front crossbeam A13 and the rear crossbeam A14, and are located on the left side of the traverse base A1. 3 touches the ground, and moves the base A1 horizontally between 15-30 mm from the ground. In this way, the entire parking rack is supported by four floating wheels (two front floating wheels A23 and two rear floating wheels A28) and two driven wheels (front driven wheels A31 and rear driven wheels A33). The parking rack moves in and out horizontally. The four floating wheels are driven by the driving motor A43 to make positive or negative rotation movements to control the lateral movement of the parking rack moving out or in, so as to achieve the purpose of parking and taking out the car.

[0061] The anti-slip device B in this embodiment includes a bearing assembly B1 and a baffle assembly B2, and the bearing assembly B1 cooperates with the baffle assembly B2.

[0062] The bearing assembly B1 in this embodiment includes a bearing frame B11, a bearing shaft B12 and a top pressure plate B16. The bearing shaft B12 is fixed on the bracket beam E. The rear end of the bearing frame B11 is installed on the bearing shaft B12. The top pressure plate B16 is installed on the front end of the bearing frame B11. A wheel blocking rod B13 is fixed on the rear end and upper part of the bearing frame B11. A floor wheel B15 is installed on the front end and lower part of the bearing frame B11. A supporting foot B14 is fixed on the bearing shaft B12.

[0063] The baffle assembly B2 in this embodiment includes a baffle frame B21, a baffle body B22, a baffle shaft B23, a limit plate B26, a limit groove B27 and a limit pin B28. The baffle frame B21 is fixed on the bracket beam E, the baffle body B22 is installed on the baffle frame B21 through the baffle shaft B23, and the baffle body B22 cooperates with the top pressure plate B16. The limit groove B27 is set on the limit plate B26, one end of the limit plate B26 is rotatably installed on the baffle frame B21, the limit pin B28 is installed at the front end of the carrier frame B11, and the limit pin B28 is located in the limit groove B27.

[0064] The baffle frame B21 in this embodiment includes a wheel baffle plate B24 and a toggle plate B25. The wheel baffle plate B24 and the toggle plate B25 are integrated into a structure with an angle between them. The toggle plate B25 is located in the front and lower part of the top pressure plate B16.

[0065] The bracket beam E in this embodiment is driven to rise and fall by two left and right lifting cylinders E1. The upper end of the piston rod of the lifting cylinder E1 is connected to the middle beam connecting plate E2 of the bracket beam E. The lower end of the cylinder barrel of the lifting cylinder E1 is connected to the rear end of the transverse base A1. A straight top cylinder E3 is provided on the transverse base A1, and the straight top cylinder E3 cooperates with the middle beam connecting plate E2.

[0066] In order to reduce the pressure of the lifting cylinder E1, save energy consumption, and protect the safety of related parts, two straight-up cylinders E3 are set at the initial stage of lifting the parking lanes F on the left and right sides. The cylinder barrel of the straight-up cylinder E3 is fixedly installed on the transverse base A1, and the upper end of the piston rod of the straight-up cylinder E3 is pressed against the lower plane of the middle beam connecting plate E2. Figure 6 In this state, the oil inlet of the straight top cylinder E3 is connected with the oil inlet of the lifting cylinder E1. When oil flows in the oil pipeline, the lifting cylinder E1 and the straight top cylinder E3 are injected with hydraulic oil at the same time. The force exerted by the straight top cylinder E3 is better than that of the lifting cylinder E1. Initially, the parking lanes F on the left and right sides are assisted by the auxiliary straight top cylinder E3, which greatly reduces the oil pressure required by the lifting cylinder E1 and the straight top cylinder E3. As the lifting angle of the parking lanes F on the left and right sides increases, the angle of force exerted by the lifting cylinder E1 also increases. At this time, the middle beam connecting plate E2 is separated from the piston rod of the straight top cylinder E3. If it continues to rise, it will be lifted to the set height by the lifting cylinder E1.

[0067] That is to say, a rotating shaft bearing seat is provided at the rear end of the carrier frame B11, and a wheel blocking rod B13 is also provided at the rear end of the carrier frame B11. A floor wheel B15 is installed under the front end of the carrier frame B11, and the rotating shaft bearing seat at the rear end of the carrier frame B11 is sleeved on the bearing shaft B12. In this way, the rear end of the carrier frame B11 rotates around the bearing shaft B12 as the axis, and the front end of the carrier frame B11 can move up and down, and the magnitude of the movement is determined by the design requirements of the limit groove B27 on the limit plate B26.

[0068] One end of the load-bearing shaft B12 is fixed to the bracket beam E, and the bracket beam E is raised by the left and right lifting cylinders E1, and the rear end of the load-bearing frame B11 is also raised, while the front end of the load-bearing frame B11 does not rise due to its own weight (or load) until the end of the limit groove B27 of the limit plate B26 is hooked with the limit pin B28 on the load-bearing frame B11 and rises synchronously.

[0069] One end of the baffle frame B21 is fixed to the outer side of the bracket beam E, and the baffle body B22 is installed on the baffle frame B21 through the baffle shaft B23, so that the baffle body B22 can rotate on the baffle frame B21 along the baffle shaft B23.

[0070] like Figure 8As shown, the parking lane F, the baffle body B22, the baffle frame B21, and the load-bearing frame B11 are all parallel to the ground. If the car is reversed onto the frame, the left and right rear tires pass through the parking lane F and reverse onto the load-bearing frame B11 until the left and right rear wheels touch the wheel blocking rod B13 to stop the vehicle; when parking begins, the bracket beam E rises, and the load-bearing shaft B12 and the baffle frame B21 installed on the bracket beam E also rise, but the front end of the load-bearing frame B11 is restrained by the load and does not rise, and the rear end of the load-bearing frame B11 rotates around the load-bearing shaft B12 as the axis, and the parking lane F rises to the set position, and the end of the limit groove B27 of the limit plate B26 collides with the limit pin B28, and then it is hooked and raised synchronously with the load-bearing frame B11.

[0071] The rear end of the carrier frame B11 rotates around the carrier axis B12, and the lifting distance of the front end of the carrier frame B11 is based on the design length of the limit groove B27 of the limit plate B26. An adjustable top pressure plate B16 is installed at the front end of the carrier frame B11 to lift the baffle body B22. From the baffle body B22, it can be seen that the baffle axis B23 is arranged at the junction of the wheel baffle plate B24 and the toggle plate B25, and there is an angle between the wheel baffle plate B24 and the toggle plate B25. When the wheel baffle plate B24 is parallel to the ground, the toggle plate B25 is at a downward angle.

[0072] The front end of the top pressure plate B16 is above the toggle plate B25. There must be a distance between the front end of the top pressure plate B16 and the baffle shaft B23. When the top pressure plate B16 moves downward with the carrier B11, the top pressure plate B16 can toggle the toggle plate B25, thereby causing the baffle body B22 to rotate along the baffle shaft B23, and the wheel block plate B24 is tilted from a state parallel to the ground to an angle to block the tire, such as Figure 7 As shown, on the contrary, when picking up the car, the bracket beam E falls, and when the landing wheel B15 contacts the ground, the load-bearing frame B11 will rotate along the load-bearing axis B12, so that the load-bearing frame B11 is in a horizontal state and flush with the parking lane F.

[0073] The left and right rear wheels of the parked vehicle fall into the carrier B11 and are blocked by the baffle body B22. The parked vehicle stops on the parking lane F, and the parking lane F lifts the vehicle at an angle. The car stops on the slope. Since the rear wheels stop on the carrier B11, the parking lane F lifts and the front end of the carrier B11 is delayed by a distance and follows the lift. At the same time, the baffle body B22 is tilted and tilted. The rear tires of the parked vehicle fall onto the carrier B11 and are blocked by the tilted baffle body B22, ensuring that the vehicle will not slide down with the slope when parked on the slope, and the parking is reliable.

[0074] A guardrail F1 is installed on the outer side of the parking lane F in this embodiment, and a roller F2 is installed on the guardrail F1. When a vehicle is parked on the parking lane F, the guardrail F1 can be used to protect the vehicle. At the same time, the roller F2 is arranged on the guardrail F1. When the wheels of the vehicle come into contact with the roller F2, the wheels can rotate to prevent the vehicle from going over the guardrail F1 and falling.

[0075] The safety device C in this embodiment includes a telescopic sleeve C1, a telescopic rod C2, a locking mechanism C3 and an unlocking mechanism C4. The telescopic rod C2 is installed in the telescopic sleeve C1, and the locking mechanism C3 and the unlocking mechanism C4 are both installed on the telescopic sleeve C1. One end of the locking mechanism C3 cooperates with the telescopic rod C2, and the other end of the locking mechanism C3 cooperates with the unlocking mechanism C4.

[0076] The locking mechanism C3 in this embodiment includes a ratchet hook C31, a ratchet hook seat C32, a ratchet shaft seat C33, a lock hook spring C34 and a spring chamber C35. The ratchet hook seat C32 is fixed on the telescopic sleeve C1, the ratchet hook C31 is installed on the ratchet hook seat C32 through the ratchet shaft seat C33, the spring chamber C35 is arranged on the ratchet hook C31, the lock hook spring C34 is located in the spring chamber C35, and the two ends of the lock hook spring C34 are respectively abutted against the outer wall of the telescopic sleeve C1 and the spring chamber C35, the ratchet hook C31 is arranged in an L-shaped structure, and a ratchet groove C22 is arranged on the telescopic rod C2, and the ratchet groove C22 is clamped with one end of the ratchet hook C31.

[0077] The unlocking mechanism C4 in this embodiment includes an electromagnet C41, an electromagnet core C42 and an electromagnet mounting seat C43. The electromagnet mounting seat C43 is fixed on the telescopic sleeve C1. The electromagnet C41 is mounted on the electromagnet mounting seat C43. The electromagnet core C42 is arranged on it, and the electromagnet core C42 cooperates with the other end of the ratchet hook C31.

[0078] The telescopic sleeve C1 in this embodiment is provided with a telescopic sleeve articulated seat C11 and a guide sleeve C12. The guide sleeve C12 is sleeved on the outside of the telescopic rod C2. A telescopic rod articulated seat C21 is provided on the upper end of the telescopic rod C2. The telescopic rod articulated seat C21 is connected to the middle beam connecting plate E2 of the bracket beam E. The telescopic sleeve articulated seat C11 is connected to the rear end of the transverse base A1.

[0079] That is to say, the telescopic sleeve C1's lower end telescopic sleeve hinge seat C11 is movably connected with the middle part of the rear cross beam A14 of the transverse base A1, the telescopic rod C2 is a one-way ratchet rod, the lower end of the telescopic rod C2 extends into the telescopic sleeve C1, and the telescopic rod hinge seat C21 at the upper end of the telescopic rod C2 is connected with the middle beam connecting plate E2 of the bracket beam E by a pin. After the upper and lower pins are connected, as the parking lane of the parking rack moves up and down, the telescopic rod C2 extends and shortens with the parking lane and moves in the telescopic sleeve C1. When the parking lane is lowered and parallel to the ground, the telescopic rod C2 extends deepest into the telescopic sleeve C1.

[0080] As the parking lane F rises, the telescopic rod C2 is also synchronously pulled out and extended from the telescopic sleeve C1. During the pulling-out process, the inclined surface of the ratchet hook C31 is meshed and pressed against the inner inclined surface of the ratchet groove C22 of the telescopic rod C2. Their meshing and pressing is positioned and fixed by the ratchet shaft seat C33. A locking hook spring C34 is provided at the lower part of the ratchet hook C31. Under the action of the spring elastic force, the inclined surface of the ratchet hook C31 is fitted with the inner inclined surface of the ratchet groove C22 of the telescopic rod C2. Due to the fitting of the inclined surfaces, the telescopic rod C2 is not blocked from stretching. The inclined surface pushes the ratchet shaft seat C33 as the center of the circle to swing clockwise. The lower locking hook spring C34 pushes the inclined surface of the telescopic rod C2 to always stick to the inner inclined surface of the ratchet groove C22 of the unidirectional telescopic rod C2. The telescopic rod C2 connected by the parking lane is also synchronously stretched without being blocked.

[0081] The parking lane F suddenly fails and falls during the lifting process, but the telescopic rod C2 connected to the parking lane F is blocked by the ratchet hook C31, which plays an important role in withstanding the fall of the parking lane F. The ratchet structure is used for one-way extension to release and retraction to block. The parking lane of the parking rack must be raised and lowered, so the parking lane is lowered to lock the telescopic rod C2 in the safety device.

[0082] The parking lane F descends normally. Before descending, the telescopic rod C2 is unlocked first. The unlocking is executed by the control circuit, and the electromagnet C41 is energized. After energization, the electromagnet core C42 is sucked down, and the lower end of the electromagnet core C42 pushes the right end of the ratchet hook C31, so that the ratchet hook C31 swings around the ratchet shaft seat C33. The electromagnet core C42 presses the right end of the ratchet hook C31 to make the left end inclined surface of the ratchet hook C31 disengage from the inner inclined surface of the ratchet groove C22 of the telescopic rod C2, and the control is released. The unlocking control circuit: the electromagnet C41 is de-energized during the entire lifting process of the parking lane F, and vice versa, the electromagnet C41 is energized during the entire descending process of the parking lane F.

The limiting frame D8 is fixed on the middle guide rail D2, and the limiting block D9 is fixed on the outer guide rail D1, and the limiting frame D8 cooperates with the limiting block D9.

[0085] The inner guide rail D3 in this embodiment is connected to the transverse base A1, and a left concave platform D10 and a right concave platform D11 are fixed on the transverse base A1. The left concave platform D10 and the right concave platform D11 cooperate with the left boss D6 and the right boss D7 respectively.

[0086] That is to say, the guide rail fixing seat D4 is provided with a guide rail fixing hole D5, and the guide rail fixing hole D5 is used to fix with the ground by using expansion screws, so that the outer guide rail D1 is laid on the ground, and the inner guide rail D3 falls into the middle guide rail D2, the outer guide rail D1 is arranged in a U-shaped structure, and can reciprocate left and right in the middle guide rail D2, the inner guide rail D3 falls into the middle guide rail D2, the middle guide rail D2 is arranged in a U-shaped structure, and can reciprocate left and right in the middle guide rail D2, the left boss D6 and the right boss D7 are fixed on the inner guide rail D3, The left concave platform D10 and the right concave platform D11 are fixed on the transverse moving base A1, the left boss D6 is clamped with the left concave platform D10, and the right boss D7 is clamped with the right concave platform D11, so that the inner guide rail D3 and the transverse moving base A1 become one, and the transverse moving base A1 moves back and forth laterally through the walking rollers (driven component A3, driving component A4) and is controlled by the rail guide to move back and forth. The telescopic guide rail can prevent the walking rollers (driven component A3, driving component A4) from deflecting when moving back and forth laterally.
