Description

Parking equipment lower bedplate L-shaped displacement mechanism
Technical Field
the invention relates to the technical field of mechanical parking equipment, in particular to lower bedplate forward-moving and rotating two-layer parking equipment.
Background
With the increase of the automobile holding amount in China, domestic mechanical parking equipment is widely applied to solve the problem of insufficient parking space. More than ten years ago, the 'upper bedplate moves forward and rotates two-layer parking equipment' (commonly called as 'no avoidance') is firstly introduced in China, and the main characteristic is that the upper bedplate needs to move forward and rotate. Later, the type of 'lower bedplate forward moving and rotating two-layer parking equipment' is also provided in China, and the main characteristic is that the lower bedplate needs to move forward, rotate and transversely move (namely 'L' -shaped displacement), and particularly the technical scheme is disclosed by a bulletin No. CN200985656Y and the name 'a forward moving and rotating avoiding type vehicle carrying device'.
Because the lower bedplate forward-moving and rotating two-layer parking equipment has unique and convenient points compared with other forms of two-layer parking equipment, related improvement schemes are continuously provided in the industry during more than ten years after the lower bedplate forward-moving and rotating two-layer parking equipment is brought out. The vehicle carrying device comprises a notice number CN201169939Y, a name of a translation and rotation avoiding type vehicle carrying device which can reliably move and rotate, a notice number CN107013068A, a name of a vehicle carrying plate motion control system, a notice number CN107023204A and a name of a novel vehicle carrying plate motion control system, and the three disclosed technical schemes have the common point that a driving system comprising an electromagnetic clutch is arranged at the bottom of a lower bedplate, and then improvement is made or an auxiliary guide mechanism is additionally arranged in a parking space based on the original rotation and the guide mechanism. However, the overall structure of these improvements, especially the rotating and guiding structure, is still relatively complex, and the manufacturing and maintenance costs are still high.
the improvement of the original technical scheme of the lower bedplate forward moving and rotating two-layer parking equipment further comprises a notice number CN106760740A and the name of a lower bedplate forward moving and rotating device, the technical scheme of the patent application discloses that rollers arranged on the left side and the right side are driven by an electromagnetic clutch at the bottom of one side of a lower bedplate far away from a lane, a linear guide unit is arranged between the two rollers to realize forward movement of the lower bedplate, and then the rotation of the lower bedplate is realized through the rotation and transverse movement guide unit provided with a short guide rail. The technical proposal is characterized in that a short guide rail and a rotating and traversing guide unit are arranged, but a method for simultaneously solving the traversing of the lower bedplate cannot be provided. The technical solution disclosed in the publication No. CN108590277A entitled "a lower platen forward movement rotating device and control method" is based on the above publication No. CN106760740A technical solution to add a straight and rotating guide rail to enhance the forward movement and rotation stability of the lower platen, but this technical solution also fails to provide a method for simultaneously solving the problem of the lateral movement of the lower platen. In other words, the two improved technical schemes also need to keep the original lower platen transverse moving driving mechanism or additionally increase the corresponding lower platen transverse moving driving mechanism, and the comprehensive effect is not obvious.
In addition, all the improved schemes have a common defect that the reversing of the lower bedplate between the linear displacement and the rotary displacement is obstructed, and the operation is not smooth.
for various reasons, the overall structure of the current product of the parking equipment in the category basically maintains the original design scheme, only the driving mode is improved, and other substantial improvements are not obvious.

preferably, in the above L-shaped displacement mechanism for a lower deck of a parking apparatus, the position detection unit is configured to detect a displacement state of the lower deck, and the position detection unit includes a forward end point detection element, a rotation end point detection element, a lateral end point detection element, and a backward end point detection element; the forward end point detection element is used for detecting the position of the lower bedplate which moves forward from the parking space position to the lane direction and reaches a forward end point; the rotation end point detection element is used for position detection of the lower bedplate which rotates by 90 degrees to reach a rotation end point after moving forwards to reach a lane position; the transverse moving end point detection element is used for detecting the position of the lower bedplate which starts to transversely move from the end point position of forward movement and rotation and reaches the end point; the backward movement end point detection element is used for detecting the position of the lower bedplate which moves backward from the lane position to the parking space direction and reaches the backward movement end point.
The above is the simplest configuration of the position detection unit. Under this arrangement, when the lower platen is reversely traversed from the traverse end position of the lane position, the above-mentioned rotary end-point detecting element simultaneously serves as the reverse traverse end-point detection; the forward end detection element is also used for the reverse rotation end detection when the lower platen rotates in the reverse direction from the rotation end position of the lane position.
Obviously, the position detection is conventional, and the detection element used may be a conventional contact rocker switch or a non-contact position switch or a photoelectric switch; the rotation detection may also employ an encoder.
Preferably, in the parking apparatus lower deck L-shaped displacement mechanism, the positioning unit is configured to position the turntable by rotation and position a movable stopper of the slidable rail by displacement.
The rotary positioning of the turntable comprises positioning when the length direction center line of the guide working surface of the slidable guide rail is vertical to the lane center line and positioning when the length direction center line of the guide working surface of the slidable guide rail is parallel to the lane center line.
The rotary positioning of the turntable belongs to the conventional and simple-structured positioning, and various common modes can be adopted. The relatively simple method is as follows: two positioning holes or positioning grooves are formed in the turntable, the difference between the two positioning holes or positioning grooves is 90 degrees, an electromagnetic push-pull element is installed on the ground or the fixed seat of the rotating and transverse moving guide unit, the electromagnetic push-pull element is provided with a telescopic rod piece, the head profile of the rod piece is matched with the positioning holes or positioning grooves formed in the turntable, and when the length direction center line of the guide working surface of the slidable guide rail is vertical to the center line of the lane, the head of the telescopic rod piece of the electromagnetic push-pull element is inserted into one positioning hole or positioning groove formed in the turntable; when the length direction central line of the guide working surface of the slidable guide rail is parallel to the central line of the lane, the head of the telescopic rod piece of the electromagnetic push-pull element is inserted into another positioning hole or positioning groove arranged on the turntable. And the mechanical mechanism positioning or the composite positioning of the electromagnetic push-pull unit and the mechanical mechanism can also be adopted.
The displacement positioning of the movable baffle comprises positioning of the movable baffle in a closed state and driving and positioning of the movable baffle in an open state.
The displacement positioning of the movable baffle belongs to the positioning with a conventional and simple structure, and various common modes can be adopted. The relatively simple method is as follows: an electromagnetic push-pull element is arranged on the outer side of the movable baffle plate arranged on the slidable guide rail, the electromagnetic push-pull element is provided with a telescopic rod piece, and the telescopic rod piece is connected with the movable baffle plate, so that two limit positions of the telescopic rod piece of the electromagnetic push-pull element, which is powered on or powered off, respectively correspond to the position of the movable baffle plate in a closed state and the position of the movable baffle plate in an open state. And the compound positioning of the electromagnetic push-pull unit and a mechanical mechanism can also be adopted.
For example, a rack I which is vertically arranged is arranged or processed on the movable baffle, and the rack I is meshed with the gear I; an electromagnetic push-pull unit and a slidable rack II are arranged on the slidable guide rail in the horizontal direction on the outer side of the movable baffle, the rack II is meshed with a gear II, and the gear II is coaxially arranged with the gear I; the telescopic rod piece of the electromagnetic push-pull unit can push the rack II to perform reciprocating linear displacement to drive the gear II to rotate, so that the gear I synchronously rotates, the rack 1 is driven to perform reciprocating displacement in the vertical direction, and the movable baffle is driven to perform reciprocating displacement in the vertical direction synchronously; the two extreme positions of the telescopic rod piece of the electromagnetic push-pull element, which are powered on or powered off, respectively correspond to the position of the movable baffle plate in a closed state and the position of the movable baffle plate in an open state. Because the slidable guide rail is displaced by external force, the displacement positioning of the movable baffle can be realized by the displacement of the slidable guide rail by adopting a purely mechanical impact rod matched with the swing fork.
Preferably, in the parking equipment lower bedplate L-shaped displacement mechanism, a universal ball device is respectively arranged on the left side and the right side below the front end of the lower bedplate, and a universal ball of the universal ball device faces the ground. When the lower bedplate is partially inclined in the displacement process or when a vehicle enters/exits the lower bedplate, the universal ball at the inclined side is contacted with the ground, and the effect of keeping the lower bedplate in a stable state is achieved. The contact of the universal ball and the ground is rolling point contact, so that the displacement of the lower bedplate is not influenced. When the number of the straight driving wheels or the rotating rollers of the front driving system is only one, a universal ball device is required to be additionally arranged.
The technical solution of the present invention is further explained below.
The displacement of the lower platen comprises linear displacement and rotary displacement; the linear displacement comprises forward movement from a parking space position to the lane direction and backward movement from the lane position to the parking space direction, and further comprises forward transverse movement and reverse transverse movement above the lane; the linear displacement of the frame requires that the rotation directions of the rotating side driving wheel, the straight-going side driving wheel and the straight-going driving wheel of the rear driving system are the same as the linear displacement direction of the lower platen and the maximum linear velocity is the same; the rotating side driving wheel, the straight-going side driving wheel and the straight-going driving wheel rotate positively at the same time, so that the lower bedplate is driven to move forwards or move forwards; the rotating side driving wheel, the straight side driving wheel and the straight driving wheel rotate reversely at the same time, so that the frame is driven to move backwards.
Therefore, when the electromagnetic clutch of the rear driving system is in an actuation working state, the lifting device of the front driving system enables the rotary roller to be separated from the contact with the ground, and finally enables the straight driving wheel to be in contact with the ground, the motor and the speed reducer of the rear driving system rotate to drive the rotary side driving wheel and the straight driving wheel to synchronously rotate, and the chain wheel and chain transmission unit of the front driving system drives the straight driving wheel to synchronously rotate; at the moment, the rear driving system and the front driving system jointly drive the lower bedplate to make linear displacement.
the rotational displacement of the lower platen first needs to satisfy the position condition: the projection of the lower platen to the axis of the output shaft of the speed reducer of the rear drive system is positioned above the gyration center line of the rotation and traverse guide unit.
When the position condition is met, the electromagnetic clutch of the rear driving system is in a disengaged non-working state, the lifting device of the front driving system enables the straight driving wheel to be disengaged from the ground, the rotating roller is enabled to be in contact with the ground, and the motor and the speed reducer of the rear driving system rotate to drive the straight driving wheel to rotate so as to push the lower bedplate to make rotary displacement; at the moment, the magnetic clutch is in a disengaged non-working state, and the rotating side driving wheel of the rear driving system rolls along with the rotation to assist the rotary displacement of the lower platen; the straight driving wheel of the front driving system is not in contact with the ground, and the rotary displacement of the lower bedplate cannot be influenced; the rotary roller rolls along with the table top to assist the rotary displacement of the table top.
The horizontal deflection angle of the rotary roller of the front driving system during installation can be obtained by drawing or calculation. The method comprises the following steps: an extension line which passes through the center of the rotating and traversing guide unit and is parallel to the central line of the lower trolley in the length direction intersects with the axis of the output shaft of the speed reducer of the rear drive system in the projection on the ground to form an intersection point, a straight line is drawn from the intersection point to the contact point of the rotating roller and the ground, and the included angle formed by the straight line and the central line of the parking space in the vehicle width direction is the horizontal deflection angle of the rotating roller when the rotating roller is installed.
When the lower bedplate is placed at a parking space, the first guide wheel and the second guide wheel are positioned on one side of the long guide rail, which is far away from the lane, and are restrained by a guide working surface of the long guide rail; the length direction center line of the guide working surface of the slidable guide rail is superposed with the length direction center line of the guide working surface of the long guide rail, and the slidable guide rail slides to one end, provided with the movable baffle, close to one end of the long guide rail close to the lane, so that the slidable guide rail is equivalent to the effective extension of the long guide rail; at this time, one end of the slidable guide rail, on which the fixed baffle is mounted, is positioned on one side close to the lane.
When the lower bedplate moves forwards from the parking space position to the lane direction, the movable baffle plate of the rotating and traversing guide unit is in an open state; when the lower bedplate moves forwards to the forward movement end position of the lane, the guide wheel I and the guide wheel II of the guide wheel unit integrally move into the slidable guide rail and are restrained by the guide working surface of the slidable guide rail; the movable baffle of the rotating and traversing guide unit is switched to a closed state, and at the moment, the lower bedplate moves forwards from the parking space position to the lane direction and reaches the forward movement end point.
When the lower bedplate rotates 90 degrees from the forward moving end position to the rotating end position, the central line of the length direction of the guide working surface of the slidable guide rail is parallel to the central line of the lane, and the lower bedplate rotates 90 degrees from the forward moving end position to the rotating end position.
When the lower bedplate starts to move transversely in the positive direction from a rotation end position, the first guide wheel and the second guide wheel of the guide wheel unit push the slidable guide rail to slide synchronously and in the same direction after contacting the fixed baffle plate arranged on the slidable guide rail until the lower bedplate reaches the end position of transverse movement; at this time, the slidable guide rail is slid to a position where the fixed stop is located away from the center line of rotation of the rotation and traverse guide unit, and at this time, the lower platen reaches the end position of the traverse.
When the lower bedplate moves in a reverse transverse movement mode from a transverse movement end position, the first guide wheel and the second guide wheel of the guide wheel unit push the slidable guide rail to synchronously and synchronously slide in the same direction after contacting the movable baffle plate arranged on the slidable guide rail until the lower bedplate reaches the reverse transverse movement end position which is also the rotation end position of the lower bedplate; at this time, the slidable guide rail is slid to a position where the fixed fence is located near a turning center line of the rotation and traverse guide unit.
When the lower platen rotates 90 degrees reversely from the rotation end position until reaching the end position of the reverse rotation operation, the position is also the forward movement end position of the lower platen; at this time, the length direction center line of the guide working surface of the slidable guide rail coincides with the length direction center line of the guide working surface of the long guide rail, and one end of the slidable guide rail, at which the movable baffle is arranged, is located at a position close to one end of the long guide rail, which is close to the lane.
When the lower bedplate moves backwards from the forward movement end position to the parking space direction, namely moves forwards reversely, the movable baffle plate arranged on the slidable guide rail is in an open state, the guide wheel I and the guide wheel II of the guide wheel unit integrally move into the long guide rail and are restrained by the guide working face of the long guide rail until the lower bedplate moves backwards to the end position, and the position is also the forward movement starting position of the lower bedplate and reaches the backward movement end position.

The embodiment of the invention discloses an L-shaped displacement mechanism of a lower bedplate of parking equipment, which further improves the driving mode of an electromagnetic clutch and forms a rear driving system, is additionally provided with a front driving system, adopts a long guide rail to match with a rotary sliding guide rail and a guide wheel for guiding, and perfectly realizes the forward movement, rotation and transverse movement of the lower bedplate, namely L-shaped displacement, without obstacle in steering, stable linear displacement and high speed.
The front drive system of the embodiment of fig. 1-12 is provided with only one straight drive wheel, one rotating wheel; in addition, two universal ball devices are provided. For the sake of clarity, fig. 1 to 12 only show the lower platen 1, the long guide rail 7-1, the displacement drive unit, the rotation and traverse guide unit, the guide wheel unit, the rear drive system, the front drive system in a schematic manner, and the position detection unit and the positioning unit are not shown.
As shown in fig. 1: the lower deck 1 rests on the floor of the parking space 2. And a long guide rail 7-1 with a groove as a guide outline is fixedly arranged on the left side line of the parking space 2. The rear end of the lower bedplate 1 is provided with a rear driving system which comprises a rotating side driving wheel 3-2, an electromagnetic clutch 6-3, a speed reducer 6-2, a motor 6-1, a straight side rotating shaft 5, a bearing seat 4 and a straight side driving wheel 3-1 from the left.
A front driving system is installed in the front position of the lower bedplate 1, a driving chain wheel 13-4 is installed in the middle position of the straight-going side rotating shaft 5, a chain 13-3 is arranged between the driving chain wheel 13-4 and a driven chain wheel 13-1, the driven chain wheel 13-1 is coaxially and tightly provided with a straight-going driving wheel 13-2, for the sake of simplicity, the speed ratio of chain wheel transmission is assumed to be 1:1, and the maximum diameter of the straight-going driving wheel 13-2 is the same as that of the straight-going side driving wheel 3-1. The middle position of the lower bedplate 1 is provided with a rotary roller 13-5; the left side and the right side of the front end are respectively provided with a universal ball II 11-2 and a universal ball I11-1.
From the foregoing, it can be seen that: the maximum diameter of a straight-moving side driving wheel 3-1 and a rotating side driving wheel 3-2 of the rear driving system is the same, and the straight-moving side driving wheel and the rotating side driving wheel are in contact with the ground; in the state shown in fig. 1, the lifting device of the front driving system drives the movable seat to move upwards, so as to drive the rotating roller 13-5 to move upwards and be separated from the contact with the ground, and the straight driving wheel 13-2 is in contact with the ground; then, the straight traveling side driving wheel 3-1, the rotation side driving wheel 3-2 and the straight traveling driving wheel 13-2 support the lower platen together and drive the lower platen 1 linearly in a displacement manner together. Of course, a plurality of straight driving wheels 13-2 can be coaxially and tightly installed with the driven chain wheel 13-1, so that more supporting points and linear displacement driving points are formed.
Referring to fig. 2, a turntable 9 is fixedly mounted at the upper left corner of the parking space 2, and a slidable guide rail 7-2 with a groove as a guide profile is arranged above the turntable 9. From the foregoing, it can be seen that: linear sliding structures matched with each other are arranged between the slidable guide rail 7-2 and the rotary table 9, and the slidable guide rail 7-2 is constrained by the rotary table 9 and can make linear displacement relative to the rotary table 9 under the action of external force; the guide profile of the slidable guide rail 7-2 is the same size as the guide profile of the long guide rail 7-1.
In the state shown in fig. 1, the center line of the guide profile of the slidable guide 7-2 is on the same line as the center line of the guide profile of the long guide 7-1. The length dimension of the effective guide profile of the slidable guide rail 7-2, namely the distance between the movable baffle plate 10-1 and the fixed baffle plate 10-2 is larger than the maximum length dimension formed between the first guide wheel 8-1 and the second guide wheel 8-2, so that when the first guide wheel 8-1 and the second guide wheel 8-2 are completely inserted onto the slidable guide rail 7-2, the effective guide profile of the slidable guide rail 7-2 can completely accommodate the first guide wheel 8-1 and the second guide wheel 8-2.
The lower end part of the slidable guide rail 7-2 shown in figure 2 is provided with a movable baffle plate 10-1. From the foregoing, it can be seen that: the flapper 10-1 has two extreme positions, one of which is in a non-blocking state and the other of which is in a blocking state. When the movable baffle 10-1 is in a non-blocking state, the first guide wheel 8-1 and the second guide wheel 8-2 can be displaced from the long guide rail 7-1 to the slidable guide rail 7-2 without any obstacle, or the first guide wheel 8-1 and the second guide wheel 8-2 can be displaced from the slidable guide rail 7-2 to the long guide rail 7-1 without any obstacle.
The upper end part of the slidable guide rail 7-2 shown in figure 2 is provided with a fixed baffle plate 10-2. From the foregoing, it can be seen that: when the first guide wheel 8-1 and the second guide wheel 8-2 are simultaneously positioned on the slidable guide rail 7-2, the second guide wheel 8-2 displaces towards the fixed baffle 10-2, and after the second guide wheel 8-2 contacts the fixed baffle 10-2, the continuous displacement of the second guide wheel 8-2 drives the slidable guide rail 7-2 to synchronously displace. When the movable baffle 10-1 is in a blocking state, if the first guide wheel 8-1 and the second guide wheel 8-2 are positioned on the slidable guide rail 7-2 at the same time, the first guide wheel 8-1 displaces towards the direction of the movable baffle 10-1, and after the first guide wheel 8-1 contacts the movable baffle 10-1, the blocking state of the movable baffle 10-1 enables the continuous displacement of the first guide wheel 8-1 to drive the slidable guide rail 7-2 to synchronously displace.
As can be seen from the figure 3, the motor 6-1, the speed reducer 6-2, the clutch 8-2, the rotating side driving wheel 3-2, the first guide wheel 8-1 and the second guide wheel 8-2 are arranged on the left side of the rear part of the lower bedplate 1.
In the state that the lower bedplate 1 shown in the figure 1 is in a standing state in the parking space 2, when the parking equipment control system commands to control the electromagnetic clutch 6-3 of the driving system to be in a suction working state, then the motor 6-1 is commanded to control to drive the speed reducer 6-2 to rotate in the forward direction, and the speed reducer 6-2 outputs in a bidirectional way; the output of one side of the table top drives a rotating side driving wheel 3-2 to rotate through an electromagnetic clutch 6-3 in a working state, the output of the other side of the table top drives a straight side driving wheel 3-1 and a straight driving wheel 13-2 of a front driving system to synchronously rotate through a straight side rotating shaft 5, and as the maximum diameters of the straight side driving wheel 3-1, the rotating side driving wheel 3-2 and the straight driving wheel 13-2 are the same, the straight side driving wheel 3-1, the rotating side driving wheel 3-2 and the straight driving wheel 13-2 synchronously rotate in the same direction, namely, the lower table top 1 is driven to move forwards; in the displacement process, the displacement track of the lower table plate 1 is restrained by the long guide rail 7-1 through the first guide wheel 8-1 and the second guide wheel 8-2, and the linear running state is continuously kept; meanwhile, the movable baffle 10-1 of the slidable guide rail 7-2 is in a non-blocking state.
Fig. 4 shows the middle of the linear forward displacement of the lower platen 1.
When the lower bedplate 1 moves forwards linearly to the position where the projection of the extension line of the central line connecting line of the straight driving wheel 3-1 and the rotating driving wheel 3-2 just passes through the center of the turntable 9, the parking equipment control system instructs the control motor 6-1 to stop running, and the lower bedplate 1 stops moving linearly; the command controls the lifting device to drive the movable seat to move downwards to drive the rotating roller 13-5 to move downwards, so that the straight driving wheel 13-2 is separated from the ground, and finally the rotating roller 13-5 is contacted with the ground. Therefore, the straight-moving side driving wheel 3-1, the rotating side driving wheel 3-2 and the rotating roller 13-5 jointly support the lower bedplate, the straight-moving side driving wheel 3-1 can drive the lower bedplate to rotate and displace, and the rotating side driving wheel 3-2 and the rotating roller 13-5 roll along with the lower bedplate during the rotation and displacement, so that the auxiliary effect is achieved. Of course, more rotating rollers can be installed to form more rotational displacement support points.
Fig. 5 shows the lower platen 1 in the aforementioned stopped linear displacement state; the position relationship of the rotary table 9, the slidable guide rail 7-2, the first guide wheel 8-1 and the second guide wheel 8-2 of the rotary guide center can be clearly seen by combining the figure 7.
In the state shown in fig. 5, after the instruction of the parking equipment control system controls the electromagnetic clutch 6-3 of the driving system to be kept in a disengaged non-working state, then the instruction controls the motor 6-1 to drive the speed reducer 6-2 to rotate in the forward direction, and the speed reducer 6-2 outputs in a bidirectional mode; because the electromagnetic clutch 6-3 is in a non-working state, one side output of the speed reducer 6-2 cannot drive the rotating side driving wheel 3-2 to rotate, and the rotating side driving wheel 3-2 is in a free rotating state; the other side output of the speed reducer 6-2 drives the straight driving wheel 3-1 to rotate through the straight rotating shaft 5; because the rotating side driving wheel 3-2 is in a free rotation state and rolls along with the rotation, the forward rotation of the straight side driving wheel 3-1 drives the lower bedplate 1 to rotate around the center of the turntable 9 in the counterclockwise direction; in the rotating process of the lower bedplate 1, the straight driving wheel 13-2 does not work because of being separated from the contact with the ground, the rotating roller 13-5 rolls with the following, and the rotating side driving wheel 3-2 also rolls with the following.
Fig. 6 shows the lower platen 1 in the middle of the illustrated counterclockwise rotational displacement. Since the rotating roller 13-5 is installed with a specific horizontal deflection angle, the rolling tangential direction of the rotating roller 13-5 is the direction indicated by the rolling direction 15.
When the lower bedplate 1 rotates and displaces 90 degrees towards the anticlockwise direction of the figure from the state of figure 5, the extension line of the central line connecting line of the rotating side driving wheel 3-2 and the straight side driving wheel 3-1 just coincides with the central line of the guide profile of the long guide rail 7-1, the parking equipment control system instructs the control motor 6-1 to stop running, and the lower bedplate 1 stops rotating and displacing.
fig. 9 shows the lower platen 1 in the aforementioned stopped rotationally displaced state.
In the state shown in fig. 9, when the parking equipment control system instructs the lifting device of the front driving system to drive the movable seat to move upward, the rotating roller 13-5 is driven to move upward and is separated from the contact with the ground, so that the straight driving wheel 13-2 is in contact with the ground; the electromagnetic clutch 6-3 of the rear driving system is controlled by an instruction to be in a suction working state, then the motor 6-1 is controlled by the instruction to drive the speed reducer 6-2 to rotate in the positive direction, and the speed reducer 6-2 outputs in two directions; the output of one side drives a rotating side driving wheel 3-2 to synchronously rotate in the same direction through an electromagnetic clutch 6-3 in a working state, the output of the other side drives a straight side driving wheel 3-1 and a straight driving wheel 13-2 to synchronously rotate through a straight side rotating shaft 5, and the three driving wheels rotate, namely, the lower bedplate 1 is driven to displace towards the left side of the figure; when the guide wheel II 8-2 contacts the fixed baffle 10-2 of the slidable guide rail 7-2, the slidable guide rail 7-2 is driven to synchronously move towards the left side of the figure; in the displacement process, the displacement track of the lower table plate 1 is restrained by the slidable guide rail 7-2 through the first guide wheel 8-1 and the second guide wheel 8-2, and the linear running state is continuously kept.
When the linear displacement of the lower bedplate 1 to the left side of the figure reaches the end position, the parking equipment control system commands the control motor 6-1 to stop rotating, and the lower bedplate 1 stops linear displacement.
Fig. 10 shows the lower platen 1 linearly displaced to the left of the figure to the end position.
Fig. 10 to 1 are the reverse operation of fig. 1 to 10, and can demonstrate the whole process of the lower bedplate 1 from the standing operation above the lane 12 to the standing operation above the parking space 2. The related actions can be derived from the above description, and are not described herein again.
The key difference between the reverse operation of fig. 10 to fig. 1 and the forward operation of fig. 1 to fig. 10 is two, the first is that when the operation is from fig. 10 to fig. 9, the movable baffle 10-1 of the slidable guide rail 7-2 needs to be driven to be at the limit position of the blocking state, so that the lower bedplate 1 is displaced towards the right side of the figure, and when the guide wheel i 8-1 contacts the movable baffle 10-1 of the slidable guide rail 7-2, the slidable guide rail 7-2 is driven to be displaced towards the right side of the figure synchronously; the second is that when moving from fig. 5 to fig. 1, the movable baffle 10-1 of the slidable guide rail 7-2 is driven to be at the limit position of the non-blocking state, so that the guide wheel I8-1 and the guide wheel II 8-2 can be displaced from the slidable guide rail 7-2 into the long guide rail 7-1 without obstruction.
Fig. 13 and 14 are schematic structural views of a long guide rail 7-1, a slidable guide rail 7-2 and related elements in one embodiment of the invention, fig. 13 is a front sectional view of a structure of the long guide rail 7-1 and the slidable guide rail 7-2, and fig. 14 is a top view of the structure of the long guide rail 7-1 and the slidable guide rail 7-2, wherein the first guide wheel 8-1 and the second guide wheel 8-2 are not shown in the top view for clarity.
In fig. 13, a fixed seat 9-1 is fixedly arranged below the left side of the ground 14; a turntable 9 is arranged above the fixed seat 9-1, and the turntable 9 can horizontally rotate relative to the fixed seat 9-1 through a bearing 9-2; a slidable guide rail 7-2 is arranged above the fixed seat 9-1; the slidable guide rail 7-2 is provided with a long groove 7-2 a; the first guide column 7-2b and the second guide column 7-2c are fixedly arranged above the fixed seat 9-1, and the long groove 7-2a is used for restraining the slidable guide rail 7-2, so that the slidable guide rail 7-2 can only make linear displacement along the left side and the right side of the figure, and the linear displacement is limited by the length of the long groove 7-2a and is also limited by the movable baffle plate 10-1 and the fixed baffle plate 10-2. Fig. 13 and 14 show that the long guide rail 7-1 is tightly installed above the right side of the ground 14.
