If the main nut beam 113 moves forward horizontally, the lower end of the main push arm 107 is driven to push forward horizontally, and the front part of the bracket 104 is driven to ascend through an inclined multi-rod mechanism formed among the main push arm 107, the upper arm 105, the lower arm 102 and the tail arm 110, so that the bracket 104 and the automobile carried by the bracket are parked obliquely; if the main nut beam 113 moves horizontally backwards, the bracket 104 and the weight of the vehicle loaded thereon press the lower end of the main push arm 107 down to press against the side of the open elongated slot 1131 of the main nut beam 113, and then move backwards along with the main nut beam 113.

As shown in fig. 4 and 7, when the jacking wheels 1124 are in contact with the lower plane of the wedge 1044, the bracket 104 is in the initial horizontal high position, at this time, the protruding shaft a1032 on the auxiliary pushing arm 103 is in fit contact with the half-shaft hole B1141 on the auxiliary nut beam 114, and the protruding shaft B1072 on the main pushing arm 107 is spaced from the half-shaft hole of the open long groove 1131 on the main nut beam 113 by an initial gap distance.

When the auxiliary push-arm support wheel 1031 and the main push-arm support wheel 1071 are in rolling contact with each other on the upper surface of the parking device base plate 101, the motion characteristics of the tilt-lift type multi-lever mechanism formed as described above make the moving speed directions of the main push-arm support wheel 1071 and the auxiliary push-arm support wheel 1031 coincide, but the moving speed of the auxiliary push-arm support wheel 1031 is faster than that of the main push-arm support wheel 1071, so that when the driving screw 108 drives the auxiliary nut beam 114 and the main nut beam 113 to move forward synchronously, the boss a1032 on the auxiliary push arm 103 is in fitting contact with the half-shaft hole B1141 on the auxiliary nut beam 114, and the boss B1072 on the main push arm 107 is at a certain initial distance from the half-shaft hole of the open long groove 1131 on the main nut beam 113 (as shown in fig. 4), the boss B1072 slides backward relative to the open long groove 1131 due to its moving speed lower than the main nut beam 113, and when the boss B1072 is in fitting contact with the half-shaft hole of the open long groove 1131 (as shown in fig. 6), the moving speed of the main push arm support wheel 1071 is the same as the moving speed of the auxiliary nut beam 114 and the main nut beam 113, and the moving speed of the auxiliary push arm support wheel 1031 is higher than the moving speed of the auxiliary nut beam 114 and is separated from it, so that the initial driving force at the time of raising the tilt multi-lever mechanism is converted from the auxiliary push arm 103 to the main push arm 107, and when the carriage 104 continues to be raised, the auxiliary push arm 103 can smoothly separate from the auxiliary nut beam 114 and be raised together with the carriage 104 (as shown in fig. 5). On the contrary, when the protruding shaft B1072 is in fit contact with the half-shaft hole of the open long groove 1131 and the driving screw 108 drives the auxiliary nut beam 114 and the main nut beam 113 to move backwards synchronously, the bracket 104 descends, the auxiliary push arm support wheel 1031 is in rolling contact with the upper surface of the transition arc plate 1015 and the upper surface of the parking device base plate 101 on the same side in sequence to drive the protruding shaft a1032 to enter the half-shaft hole B1141 to be in fit contact therewith, at this time, the moving speed of the auxiliary push arm support wheel 1031 is consistent with the moving speed of the main push arm support wheel 1071 due to the limitation of the auxiliary nut beam 114, and the moving speed of the main push arm support wheel 1071 is smaller than the moving speed of the main nut beam 113 to make the protruding shaft B1072 slide forwards relative to the open long groove 1131, so that the conversion of the driving force from the main push arm 107 to the auxiliary push arm 103 when the tilt multi-lever mechanism descends to the lower position is completed.

Because the inclined lifting parking device 1 is located below a chassis of a ground automobile when initially working, and the included angle between the main push arm 107 and the horizontal plane is too small, which results in that the driving force of the screw rod is too large and is difficult to drive, when the bracket 104 ascends, the driving screw rod 108 initially pushes the auxiliary push arm 103 which is short in size and large in included angle with the horizontal plane, so that the thrust of the screw rod can be effectively reduced, when the main push arm 107 advances to form a large angle with the horizontal plane, the screw rod is switched to push the main push arm 107, and the whole ascending process can be continuously completed, otherwise, the same is carried out.

When the front part of the bracket 104 is lifted, after the auxiliary push arm 103 is separated from the auxiliary nut beam 114, the auxiliary nut beam 114 moves to be separated from the driving screw rod 108 and the movement of the screw nut sliding pair, so that the auxiliary nut beam is positioned on the optical axis section of the driving screw rod 108; when the front part of the bracket 104 descends, after the auxiliary push arm 103 falls and is connected to the auxiliary nut beam 114, the auxiliary push arm 103 pushes the auxiliary nut beam 114 to move towards the threaded section of the driving screw rod 108, so that the auxiliary nut beam 114 enters the threaded section and the driving screw rod 108 forms a screw-nut sliding pair.

When the four bracket telescopic legs 1041 extend out, they are located just under the girders on both sides of the bottom of the vehicle body.

In specific implementation, the number of the bracket telescopic legs 1041 is four, and the four bracket telescopic legs 1041 penetrate through the two ends of the two hollow rectangular tubular beams in the width directions of the front portion and the middle rear portion of the bracket frame body 1042 respectively, and can slide and stretch along the inner walls of the corresponding rectangular tubular beams respectively.

The jacking cylinder 1123 drives the front and rear jacking wheels 1124 to horizontally slide along the short horizontal guide rail 1013, so as to drive the jacking wheels 1124 to contact the inclined plane of the wedge 1044 to push the bracket 104 to slightly rise/fall; meanwhile, the jacking wheel 1124 at the rear part of the parking device base plate 101 slides and drives the bearing cushion 1122 to horizontally slide back and forth through the following slide block 1121, so that the tail arm vertical sliding shoe 111 can vertically slide up and down along the vertical short guide rail 1012 under the condition of being limited by the sliding pair of the vertical short guide rail 1012 and the wedge surface of the bearing cushion 1122.

Since the bracket tail wheels 106 hinged on the bracket 104 can only vertically move along the vertical long guide rails 1011 on both sides of the rear part of the parking device base plate 101, when the piston rods of the jacking cylinders 1123 on both sides simultaneously extend forwards, the four jacking wheels 1124 roll along the sides of the wedge 1044 to drive the bracket 104 and the tail arm vertical sliding shoe 111 to vertically rise, and at the same time, the rear following slide block 1121 also drives the bearing cushion 1122 to slide forwards.

Specifically, the initial advancing directions of the wheels of the direction driving wheel 21 and the follow-up universal wheel 24 are forward, when the front vehicle needs to leave the access passage, the direction driving wheel 21 is driven by the self-contained motor to roll forward so as to drive the front mobile chassis 2 to move forward, and at the moment, the guide trolley 32 also moves forward along the guide rail 31. The upper surface of the foremost end of the guide rail 31 is provided with a positioning hole, when the guide trolley 32 reaches the foremost end of the guide rail 31, the positioning pin 42 arranged on the guide trolley 32 falls into the positioning hole due to self weight, at this time, the turning cylinder 22 retracts to pull the direction driving wheel 21 to rotate and change the advancing direction, and the front moving chassis 2 rotates around the hinged position of the connecting arm 33 and the guide trolley 32 under the driving of the direction driving wheel 21 to further advance to a position parallel to the parking space width direction.

The specific implementation process of the invention is as follows:

as shown in fig. 1 and fig. 3, two cars are normally parked in the same conventional car parking space front and back respectively by means of a front parking device and a rear parking device, the front and rear car-parking devices 1 are in the maximum inclined state during normal parking, and the front parts of the two cars are tilted upward.

When the front vehicle is going to take out and go out, the front mobile chassis 2 carries the front vehicle to move forwards, when the front mobile chassis is moved out to the positioning pin 42 arranged on the guide trolley 32 and falls into the positioning hole at the foremost end of the guide rail 31, the direction driving wheel 21 at the bottom of the front mobile chassis 2 changes the advancing direction under the pulling of the turning cylinder 22, so that the front mobile chassis 2 carries the front vehicle to rotate to the direction parallel to the public driving channel around the hinged position of the connecting arm 33 and the guide trolley 32, and then the inclined lifting parking device 1 on the front mobile chassis 2 starts to descend.

At the beginning of descending, as shown in fig. 2 and fig. 6, the inclined parking device 1 is in the highest lifting state, at this time, the four bracket telescopic legs 1041 on the bracket 104 are extended to support the weight of the vehicle, the auxiliary nut beam 114 is parked at the optical axis section 1081 at the front end of the driving screw 108, and due to the action of gravity load, the protruding shaft B1072 on the main push arm 107 is in fit contact with the half-axis hole of the open long slot 1131 on the main nut beam 113. When lowered, the drive screw 108 rotates to drive the main nut beam 113 rearward, and the carriage 104 is then lowered with the vehicle, as shown in figure 4, when the auxiliary push arm support wheel 1031 passes over the upper surface of the same side transition arc 1015 to the upper surface of the parking base plate 101 to approach the auxiliary nut beam 114, the auxiliary push arm 103 first contacts a buffer spring (not shown) on the auxiliary nut beam 114, thereby pushing the auxiliary nut beam 114 to be engaged with the driving screw 108 in advance to start moving backward synchronously with the main nut beam 113, and then, the auxiliary push arm support wheel 1031 catches up the auxiliary nut beam 114 to drive the protruding shaft a1032 to enter the half shaft hole B1141 to be in fit contact therewith, at the same time, the protruding shaft B1072 will disengage from the half-axle hole of the open long slot 1131, completing the conversion of power from the main push arm 107 to the auxiliary push arm 103, and then the auxiliary push arm 103 will drive the bracket 104 to further descend to the horizontal position.

As shown in fig. 7, when the bracket 104 is lowered to the horizontal level, the four wheels of the vehicle contact the upper surface of the forward moving chassis 2 (for the rear vehicle, the four wheels are grounded), then the four jacking wheels 1124 contact the lower surfaces of the four wedges 1044 on the bracket 104 to support the bracket 104, and the four bracket telescopic legs 1041 still extend outwards to support the vehicle chassis. Further, in order to enable the automobile to smoothly leave the parking space from the bracket 104, the driving screw 108 continues to rotate to drive the auxiliary nut beam 114 to move backwards for a short distance to be separated from the contact with the auxiliary pushing arm 103, the piston rods of the jacking cylinders 1123 on the two sides simultaneously extend backwards to drive the four jacking wheels 1124 and the two bearing pads 1122 on the rear portion to move backwards, under the action of self weight, the bracket 104 descends in a translation manner, when the bracket 104 descends to the position where the lower surface contacts with the upper surface of the front movable chassis 2 (for the rear automobile, the upper surface of the front movable chassis is the ground), the lower surface reaches the lowest position, at the moment, the four bracket telescopic legs 1041 are separated from the automobile chassis and then retract to avoid blocking the automobile wheels to move forwards, and accordingly, the front automobile can start the parking device leaving the front position.

After the front vehicle is driven away, the inclined parking device 1 on the front mobile chassis 2 still rises to the highest position according to the reverse steps, then the front mobile chassis 2 rotates to the length direction of the parking space, and after the electromagnet 41 on the positioning pin assembly 4 is electrified to lift the positioning pin 42, the front mobile chassis 2 can continue to move backwards along the length direction of the parking space to the position of initial parking.

When the rear vehicle needs to be taken out and run, as shown in fig. 1, the front moving chassis 2 needs to carry the front vehicle to move forward and rotate to a direction parallel to the public traffic lane according to the above steps, the inclined lifting parking device 1 of the rear parking device also needs to carry the rear vehicle to descend to the lowest position according to the above steps, and the rear vehicle can be driven out of the parking space after the four bracket telescopic legs 1041 retract. After the rear vehicle is driven away, the inclined lifting parking device 1 of the rear parking device still needs to be lifted to the highest position, and the front moving chassis 2 carries the front vehicle to return to the original initial parking position.

After the front vehicle or the rear vehicle takes the vehicle, the front-position moving chassis 2 needs to return to the initial position, and the two inclined lifting parking devices 1 also need to return to the initial highest position, so when the front vehicle or the rear vehicle needs to be parked in a garage, except that the vehicle needs to be backed in the garage, the action sequence of the front-position parking device and the rear-position parking device is consistent with the action sequence of the vehicle taking.
