Description

Technical Field

[0001] The present invention relates to the field of parking equipment, in particular to a vehicle loading plate steering mechanism and parking equipment. Background Art

[0002] With the increasing number of cars on the road, mechanical parking systems have become widely used to solve parking problems. Some systems have parking spaces with a length perpendicular to the lane (where the length of the parking space is the "longitudinal" direction and the lane is the "transverse" direction, with the "transverse" direction being perpendicular to the "longitudinal" direction). Typically, a vehicle's position is switched between the parking space and the lane by turning the vehicle carrier 90 degrees between the parking space and the lane.

[0003] The vehicle carrier plate often needs to be coordinated with a steering mechanism in order to make a 90-degree turn between the parking space and the lane. The vehicle carrier plate steering mechanism used in existing parking equipment, such as the "Ground Vehicle Platform Rotatable Transverse Parking Garage" disclosed in the Chinese invention patent with publication number CN115324404A, connects the longitudinal guide rail in the parking space and the transverse guide rail in the lane through a section of circular guide rail. The rollers on the vehicle platform run on the circular guide rail to achieve a 90-degree turn between the parking space and the lane. However, the circular guide rail not only has a complicated manufacturing process, high manufacturing cost, and high installation requirements, but also when the rollers run on the circular rail, the positioning accuracy between the two is poor, resulting in unstable operation of the vehicle platform when turning, reducing the reliability and stability of the parking equipment.

[0077] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0078] One of the purposes of the present invention is to provide a new type of vehicle loading plate steering mechanism, which can realize the arc-free transition steering of the vehicle loading plate, so as to solve the problem that the arc guide rail of the existing vehicle loading plate steering mechanism is not only complicated in manufacturing process, high in manufacturing cost and high in installation requirements, but also the roller runs on the arc track with poor positioning accuracy, resulting in unstable operation of the vehicle platform when turning, thereby reducing the reliability and stability of the parking equipment.

[0079] Another object of the present invention is to provide a parking device having the above-mentioned vehicle loading plate steering mechanism.

[0080] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Example 1

[0081] The present embodiment provides a new type of vehicle loading plate steering mechanism 100, which is used to be arranged on the parking space 2 of the parking equipment to convert the position of the vehicle loading plate between the parking space 2 and the lane. The vehicle loading plate steering mechanism 100 includes a longitudinal guide mechanism, a reversing mechanism, a steering mechanism, a vehicle loading plate 3 and a driving mechanism, wherein the longitudinal guide mechanism is arranged close to the longitudinal edge line on one side of the parking space 2 and is parallel to the longitudinal edge line; the reversing mechanism is movably connected to the longitudinal guide mechanism through a connecting mechanism, and can slide along the longitudinal guide mechanism under the action of the connecting mechanism to convert the reversing mechanism between a first state and a second state, wherein in the first state, the reversing mechanism is located at the end of the longitudinal guide mechanism away from the lane, and in the second state, the reversing mechanism is located at the end of the longitudinal guide mechanism close to the lane; the steering mechanism is arranged at the end of the longitudinal guide mechanism close to the lane, and can There is no arc transition rotation guide to enable the reversing mechanism to switch between the second state and the third state, wherein, in the third state, the reversing mechanism is separated from the longitudinal guide mechanism and arranged close to the lane edge line, and the intersection of the lane edge line and the longitudinal edge line is the rotation center of the vehicle loading plate; the vehicle loading plate 3 is connected to the reversing mechanism and is used to carry the vehicle. When the reversing mechanism is in the first state, the vehicle loading plate 3 is located in the parking space 2, when the reversing mechanism is in the second state, the vehicle loading plate 3 is located at the rotation center of the vehicle loading plate waiting for turning, and when the reversing mechanism is in the third state, the vehicle loading plate 3 is located in the lane; the driving mechanism can drive the reversing mechanism to move to provide driving force for the conversion of the reversing mechanism between the first state, the second state and the third state.

[0082] In this embodiment, the longitudinal guide mechanism is a longitudinal guide rail 1, and the reversing mechanism is a reversing guide rail 4. In the first and second states, the reversing guide rail 4 is parallel to the longitudinal guide rail 1. In the third state, the reversing guide rail 4 is parallel to the lane edge, which is the extension direction of the lane. The parking space 2 is generally a rectangular parking space on the ground. In actual application, the plane orientation of the parking space 2 is defined as follows: the side close to the lane is the front end, the corresponding transverse edge is the front edge 23, and the side opposite to the front edge 23 is the rear end edge 21; the side with a zero turning radius (or a smaller turning radius) of the loading plate 3 is the inner side, the corresponding longitudinal edge is the inner edge 24, and the side opposite to the inner edge 24 is called the outer edge 22. The rear end edge 21, the outer edge 22, the front edge 23, and the inner edge 24 together enclose a rectangular parking space 2. Generally, the lane is perpendicular to the longitudinal direction of the rectangular parking space 2, and the lane edge coincides with the front edge 23. When the rectangular loading plate 3 is located in the parking space 2, its longitudinal direction (i.e., the front-to-back direction of the vehicle parked on the loading plate 3) is consistent with the longitudinal direction of the parking space 2. The intersection of the aforementioned front edge 23 and the inner edge 24 is the rotation center point of the loading plate 3. The description of the specific plane orientation of the loading plate 3 is limited to reference to the parking space 2, and is based on the state of the loading plate being completely parked in the parking space. In actual operation, the angle between the lane edge and the inner edge 24 or outer edge 22 of the parking space 2 is 90 degrees to 180 degrees. Generally, 90 degrees is the best design solution, that is, the lane edge is perpendicular to the longitudinal direction of the parking space 2. Based on this, when the loading plate switches positions between the parking space 2 and the lane, the conversion angle is 90 degrees, that is, a right-angle turn.

[0083] In this embodiment, when the vehicle loading plate 3 is completely parked in the parking space 2, the reversing guide rail 4 is arranged on the side of the vehicle loading plate 3 close to the inner side line 24, and the reversing guide rail 4 is parallel to the longitudinal direction of the vehicle loading plate 3. Therefore, in this solution, the reversing guide rail 4 serves as both a connecting structure between the vehicle loading plate 3 and the vehicle loading plate steering mechanism 100 and a reference mechanism of the vehicle loading plate 3. That is, the swinging state of the reversing guide rail 4 is completely consistent with the swinging state of the vehicle loading plate 3 (including the swinging direction and the swinging angle, etc.). Therefore, the state transition of the vehicle loading plate 3 can be represented in real time by the state transition of the reversing guide rail 4 relative to the longitudinal guide rail 1. The reversing guide rail 4 can be regarded as a part of the structure of the vehicle loading plate 3.

[0084] In this embodiment, Figures 1 to 4As shown, the steering mechanism includes a transverse guide rail 58 and a rotational displacement positioning mechanism, wherein the transverse guide rail 58 is arranged at the front edge line 23 of the parking space 2, one end of the transverse guide rail 58 intersects at a right angle with the end of the longitudinal guide rail 1 close to the lane, has no arc-shaped guide rail, and forms a track intersection, which coincides with the rotation center point of the right-angle turn of the vehicle loading plate 3. The longitudinal guide rail 1 extends from the track intersection position to the inside of the parking space 2, and the length dimension is greater than the length dimension of the vehicle loading plate 3 required for longitudinal displacement. Correspondingly, the transverse guide rail 58 extends from the track intersection position to the position away from the parking space 2, and the length dimension is greater than the length dimension of the vehicle loading plate 3 required for lateral displacement. The rotational displacement positioning mechanism includes a ground component, a vehicle plate component and a lifting drive mechanism 1, wherein the ground component is arranged at the intersection of the tracks, and includes a rotating component 1 whose rotation center line is perpendicular to the ground; the vehicle plate component is arranged on the reversing guide rail 4, and includes a rotating component 2 whose rotation center line is perpendicular to the ground, and when the reversing guide rail 4 is in the second state, the rotation center line of the rotating component 2 coincides with the rotation center line of the rotating component 1; the lifting drive mechanism 1 is a reciprocating linear displacement drive mechanism, and when the reversing guide rail 4 is in the second state, the lifting drive mechanism 1 can drive at least one of the rotating component 1 and the rotating component 2 to rise and fall linearly, so that the rotating component 1 and the rotating component 2 can be converted between a combined state and a separated state, wherein, in the combined state, the rotating component 1 and the rotating component 2 are combined to form a fixed-point rotation mechanism, and the reversing guide rail 4 can be converted between the second state and the third state under the driving action of the drive mechanism; in the separated state, the rotating component 1 and the rotating component 2 are away from each other.

[0085] The above-mentioned lifting drive mechanism can actually be a linear motor, a motor or an electromagnetically driven gear rack, a cam, a screw rod, etc., which are not listed here one by one.

[0086] In the initial state, the loading plate 3 is located in the inner area of ​​the parking space 2, and the operation process of the loading plate steering mechanism 100 is as follows:

[0087] 1. The driving roller of the driving mechanism drives the vehicle carrier 3 to move longitudinally and linearly into the lane area under the guidance of the connecting mechanism until the rotation center line of the rotating part 1 coincides with the rotation center line of the rotating part 2, and the driving roller stops driving;

[0088] 2. The rotating component 1 and the rotating component 2 are combined and in a combined state;

[0089] 3. The driving roller of the driving mechanism drives the loading plate 3 to rotate 90° toward the outside of the parking space 2 so that the longitudinal centerline of the loading plate 3 is parallel to the centerline of the lane;

[0090] 4. The rotating component 1 is separated from the rotating component 2 and is in a separated state;

[0091] 5. The driving roller of the driving mechanism drives the vehicle loading plate 3 to move laterally and linearly under the guidance of the connecting mechanism, deviating from the parking space 2 position until it reaches the end of the lateral displacement. The driving roller stops driving, and the vehicle loading plate 3 is located at the end position of the lane area, and the operation process is completed.

[0092] In the initial state, the vehicle loading plate 3 is located at the end position of the lane area, and the operation process of the vehicle loading plate steering mechanism 100 is as follows:

[0093] 1. The driving roller of the driving mechanism drives the vehicle loading plate 3 to move laterally linearly toward the parking space 2 under the guidance of the connecting mechanism until it reaches the starting point of the lateral displacement. The rotation centerline of the rotating component 1 coincides with the rotation centerline of the rotating component 2, and the driving roller stops driving.

[0094] 2. The rotating component 1 and the rotating component 2 are combined and in a combined state;

[0095] 3. The driving roller of the driving mechanism drives the loading plate 3 to rotate 90° toward the inside of the parking space 2, so that the longitudinal center line of the loading plate 3 is parallel to the center line of the parking space 2;

[0096] 4. The rotating component 1 is separated from the rotating component 2 and is in a separated state;

[0097] 5. The driving roller of the driving mechanism drives the vehicle loading plate 3 to move longitudinally into the parking space 2 area under the guidance of the connecting mechanism until the vehicle loading plate 3 is located at the end position of the inner area of ​​the parking space 2. The driving roller stops driving and the operation process of the vehicle loading plate 3 is completed.

[0098] Furthermore, in this embodiment, the above-mentioned connection mechanism cooperates with the longitudinal guide rail 1 to realize longitudinal displacement guidance of the reversing guide rail 4, and cooperates with the transverse guide rail 58 to realize transverse displacement guidance of the reversing guide rail 4. Specifically, the above-mentioned connection mechanism includes a guide component and an anti-interference component. The guide component is provided on the reversing guide rail 4 and is one of the guide structure 1, the guide structure 2 and the guide structure 3, wherein the guide structure 1 includes at least two rollers with their rotation center lines arranged horizontally, and the rollers can roll with the top and both sides of the longitudinal guide rail 1 and the transverse guide rail 58; the guide structure 2 includes at least two rollers with their rotation center lines arranged vertically, and the rollers can roll with the grooved inner surfaces of the longitudinal guide rail 1 and the transverse guide rail 58; the guide structure 3 includes at least two groups, each group of at least two rollers with their rotation center lines arranged vertically, and the rollers can roll with the two side surfaces of the longitudinal guide rail 1 and the transverse guide rail 58. The anti-interference component adopts one of an anti-interference structure 1 and an anti-interference structure 2, which is used to prevent the longitudinal guide rail 1 and the transverse guide rail 58 from interfering with the guide component when it rotates with the reversing guide rail 4. The anti-interference structure 1 is an avoidance notch provided at the corresponding position of the longitudinal guide rail 1 and the transverse guide rail 58; the anti-interference structure 2 is a lifting drive mechanism 2 provided on the reversing guide rail 4. The lifting drive mechanism 2 is a reciprocating linear displacement drive mechanism used to drive the guide component toward or away from the longitudinal guide rail 1 or the transverse guide rail 58, so that the guide component and the longitudinal guide rail 1 or the transverse guide rail 58 are guided and matched, or the guide component and the longitudinal guide rail 1 or the transverse guide rail 58 are separated and avoided. When the height position of the guide component is driven by the lifting drive mechanism 2 and is in the upper limit position, the lower limit position of the guide component corresponds to the normal working state of contact with the longitudinal guide rail 1 or the transverse guide rail 58, and the upper limit position corresponds to the avoidance state of disengagement from the longitudinal guide rail 1 or the transverse guide rail 58.

[0099] In this embodiment, the operating timing of the lifting drive mechanism 2 and the lifting drive mechanism 1 are the same and the setting positions are similar. Like the lifting drive mechanism 1, the lifting drive mechanism 2 is also preferably a simple reciprocating linear displacement drive unit, including a linear motor, an electromagnetic or motor-driven gear rack, a cam, a screw rod, etc., which are not listed here one by one. In addition, since the operating timing of the lifting drive mechanism 2 and the lifting drive mechanism 1 are the same and the setting positions are similar, the power unit of the lifting drive mechanism 2 can be cancelled, and the related functions are realized by the lifting drive mechanism 1. Even if there is a situation where the operating effects of the two are opposite, it is only necessary to add a reverse operating mechanism to the terminal structure of the lifting drive mechanism 1 (such as the two ends of the hinge, cams with different lifting surfaces, and two racks driven by the same gear), which are not listed here one by one.

[0100] In this embodiment, the cross-sections of the longitudinal guide rail 1 and the transverse guide rail 58 include the following three types:

[0101] 1. Suitable for the above-mentioned guide structure 1, the guide rail cross-section is a solid outer rectangular, outer circular, outer trapezoidal or outer triangular shape, and the outer edge cross-sectional shape of the roller matches the cross-sectional shape of the upper and both sides of the longitudinal guide rail 1 and the transverse guide rail 58.

[0102] 2. Suitable for the above-mentioned guide structure 2, the guide rail cross-section is an inner groove type, and the outer diameter of the roller matches the width of the inner groove.

[0103] 3. Suitable for the above guide structure 3, the guide rail cross-section is an outer rectangle, and the distance between two rollers in the same group matches the width of the outer rectangle.

[0104] In this embodiment, the driving mechanism is arranged at the rear end of the vehicle loading plate 3, and is a driving wheel driven by a motor reducer to rotate. Specifically, one of the following driving mechanism 1, driving mechanism 2 and driving mechanism 3 is adopted, wherein:

[0105] Drive mechanism 1 includes a motor reducer, an inner drive wheel, an outer drive wheel, and a follower roller. The motor reducer has outputs at both ends. The inner drive wheel is located on the side of the rear end of the vehicle carrier 3 close to the longitudinal track. The output end of the motor reducer is connected to the inner drive wheel through a clutch. The outer drive wheel is located on the side of the rear end of the vehicle carrier 3 opposite the inner drive wheel. The other output end of the motor reducer is directly connected to the outer drive wheel. There is at least one follower roller located at the front end of the vehicle carrier 3. This drive mechanism uses dual drive wheels. When the vehicle carrier 3 is displaced longitudinally or laterally, the clutch is engaged, and the inner and outer drive wheels rotate synchronously, with the same maximum linear velocity in contact with the ground. When the vehicle carrier 3 is rotationally displaced, the clutch is disengaged, and the outer drive wheel rotates, driving the vehicle carrier 3 to rotate around the rotation centerline of the rotational displacement positioning mechanism, with the inner drive wheel following. The advantages of this solution are stable drive and less wear on the ground. The disadvantage is that the cost is relatively high.

[0106] Drive mechanism 2 includes a motor reducer, a drive wheel, and a follower wheel. The drive wheel is located in the middle of the rear end of the vehicle carrier 3, and the motor reducer is connected to the drive wheel. The follower wheel is located at the front end of the vehicle carrier 3. There are generally multiple follower wheels, one on the left and one on the right side of the front end of the vehicle carrier 3. This drive mechanism adopts a single drive wheel design, with the vehicle carrier 3 driven by a single drive wheel for longitudinal, lateral, and rotational displacement. This solution has the advantage of relatively low cost, but also relatively weak driving capacity and greater wear on the ground.

[0107] Drive mechanism 3, not shown in the figure, includes an inner motor reducer, an outer motor reducer, an inner drive wheel, an outer drive wheel, and a follower roller. The inner drive wheel is located at the rear end of the vehicle carrier 3, close to the longitudinal track. The inner motor reducer is connected to the inner drive wheel. The outer drive wheel is located at the rear end of the vehicle carrier 3, opposite the inner drive wheel. The outer motor reducer is connected to the outer drive wheel. The follower roller is located at the front end of the vehicle carrier 3. This solution provides a stable drive form, but the cost is relatively high.

[0108] As can be seen from the above, one of the key points of this technical solution is that a transverse guide rail 58 is provided on the front edge 23 of the parking space 2 and perpendicularly intersects the longitudinal guide rail 1. Figures 1 to 4 The specific example shown is used to specifically illustrate the working process and working principle of the vehicle loading plate steering mechanism 100 of this embodiment:

[0109] The driving mechanism on the vehicle loading plate 3 adopts the above-mentioned driving mechanism 2, and is only equipped with one driving wheel, namely the driving wheel 57, so it is a single driving wheel type.

[0110] like Figure 1 As shown, the longitudinal guide rail 1 is arranged at the inner edge 24 of the parking space 2, the loading plate 3 is parked on the parking space 2, the reversing guide rail 4 is installed at the rear end of the loading plate 3, and roller one 51, roller two 52, roller three 53 and roller four 54 are installed near the inner side of the reversing guide rail 4. Roller one 51 and roller two 52 are a pair, which respectively clamp the two outer vertical surfaces of the longitudinal guide rail 1. Similarly, roller three 53 and roller four 54 are a pair, which respectively clamp the two outer vertical surfaces of the longitudinal guide rail 1; a transverse guide rail 58 is installed near the lane and facing outward; a guide post hole 56 is provided at the intersection of the longitudinal guide rail 1 and the transverse guide rail 58.

[0111] like Figure 2 As shown, the vehicle loading plate 3 is driven by the driving wheel 57 and moves longitudinally into the lane position under the clamping and guidance of the longitudinal guide rail 1 by roller 1 51, roller 2 52, roller 3 53 and roller 4 54 until the rotation center lines of the guide post 55 and the guide post hole 56 coincide with each other; at this time, roller 1 51, roller 2 52, roller 3 53 and roller 4 54 are driven upward and disengage from the clamping of the longitudinal guide rail 1; the guide post 55 is driven downward and enters the interior of the guide post hole 56, forming a fixed-point rotation mechanism.

[0112] like Figure 3 As shown, the vehicle loading plate 3 is driven by the driving wheel 57 to rotate 90° clockwise until the longitudinal center line is parallel to the lane edge line; at this time, the guide post 55 is driven upward and exits the inner area of ​​the guide post hole 56; roller 1 51, roller 2 52, roller 3 53, and roller 4 54 are driven downward to clamp the two outer facades of the transverse guide rail 58.

[0113] like Figure 4 As shown, the vehicle loading plate 3 is driven by the driving wheel 57 and is laterally displaced to the left side of the figure under the clamping guidance of the roller 1 51, roller 2 52, roller 3 53 and roller 4 54 on the transverse guide rail 58 until it reaches the end (terminal) position.

[0114] The reverse direction reset operation of the vehicle loading plate 3 can refer to the above description, press Figure 4 、 Figure 3 、 Figure 2 、 Figure 1 The order of execution is not described here.

[0115] It can be seen that the vehicle loading plate steering mechanism 100 proposed in the present technical solution adopts the form of cooperation between the guide component and the vertical corner track to realize the arc-free transition and right-angle reversal of the reversing guide rail and the vehicle loading plate. Compared with the existing arc guide rail setting, the structure is simpler, and the manufacturing cost and installation requirements are reduced. At the same time, since the use of rollers and arc tracks is eliminated, the vehicle loading plate steering mechanism 100 of the present technical solution is more stable in operation and has higher positioning accuracy when steering the vehicle loading plate 3, which is beneficial to improving the overall reliability and stability of the parking equipment. Example 2

[0116] This embodiment proposes a vehicle loading plate steering mechanism 100, which is consistent with the design concept of the vehicle loading plate steering mechanism in Example 1, that is, a guide component is matched with a vertical corner rail to achieve arc-free transition and right-angle reversal of the reversing guide rail and the vehicle loading plate. However, the arrangement of the guide components in the driving mechanism and the connecting mechanism in this embodiment is different from that in Example 1. Except for the driving mechanism and the connecting mechanism, the remaining structures are similar to those in Example 1 and will not be repeated here.

[0117] like Figures 5 to 8 As shown, the driving mechanism on the vehicle loading plate 3 adopts the driving mechanism 1 in the embodiment 1, that is, the inner driving wheel 64 is set on the inner side of the rear end of the vehicle loading plate 3, and the outer driving wheel 66 is set on the outer side of the rear end, so the driving mechanism is a double driving wheel form.

[0118] like Figure 5 As shown, the longitudinal guide rail 1 is arranged at the inner edge 24 of the parking space 2, and the loading plate 3 is parked on the parking space 2. Roller 1 61 and roller 2 62 are installed at the rear end near the inner position, which are clamped by the inner vertical surface of the longitudinal guide rail 1, that is, the longitudinal guide rail 1 is a groove-type guide rail; a transverse guide rail 67 is installed near the lane and facing the outside, and the transverse guide rail 67 is a groove-type guide rail, which can clamp roller 1 61 and roller 2 62 through the inner vertical surface; a guide post hole 63 is provided at the vertical intersection of the longitudinal guide rail 1 and the transverse guide rail 67.

[0119] like Figure 6As shown, the clutch 65 is in the engaged state, and the carrier plate 3 is driven by the inner drive wheel 64 and the outer drive wheel 66, and moves longitudinally into the lane position under the clamping guidance of the roller 1 61 and the roller 2 62 of the longitudinal guide rail 1 until the rotation center lines of the roller 2 62 and the guide post hole 63 coincide with each other; at this time, the roller 1 61 is driven upward and breaks away from the contact with the longitudinal guide rail 1; the roller 2 62 is driven downward as a guide post and enters the interior of the guide post hole 63, forming a fixed-point rotation mechanism.

[0120] like Figure 7 As shown, the clutch 65 is in the disengaged state, and the carrier plate 3 is driven by the outer drive wheel 66 to rotate 90° clockwise until the longitudinal center line is parallel to the lane edge line; at this time, the roller 2 62 is driven upward and exits the inner area of ​​the guide post hole 63; the roller 1 61 is driven downward and clamped by the inner vertical surface of the transverse guide rail 67.

[0121] like Figure 8 As shown, the clutch 65 is in the engaged state, and the carrier plate 3 is driven by the inner drive wheel 64 and the outer drive wheel 66, and is laterally displaced to the left side of the figure under the clamping guidance of the transverse guide rail 67 on the roller 1 61 and the roller 2 62 until it reaches the end (terminal) position.

[0122] The reverse direction reset operation of the vehicle loading plate 3 in this embodiment can refer to the above description. Figure 8 、 Figure 7 、 Figure 6 、 Figure 5 The order of execution is not described here.

[0123] It can be seen that the vehicle loading plate steering mechanism 100 proposed in this solution realizes arc-free transition and right-angle steering of the vehicle loading plate in a simple, reliable and low-cost manner, overcoming the shortcomings of current technology. Example 3

[0124] The difference between this embodiment and the first and second embodiments is that the vehicle loading plate steering mechanism 100 proposed in this embodiment does not have an L-shaped corner structure formed by the vertical intersection of the longitudinal guide rail 1 and the transverse guide rail. Figures 9 to 12As shown, the steering mechanism in this embodiment includes a panel 73, a swing guide rail 74 and a transverse guide component. The panel 73 is rotatably set on the parking space 2 and is arranged near the front edge line of the parking space 2; the swing guide rail 74 is set at the end of the longitudinal guide rail 1 close to the lane and is connected to the panel 73 to form a rotation point. The swing guide rail 74 can swing around the rotation point under the driving action of the driving mechanism to realize the conversion of the swing guide rail 74 between the longitudinal extension state and the transverse movement state. In the longitudinal extension state, the center line of the swing guide rail 74 coincides with the center line of the longitudinal guide rail 1, and the end of the swing guide rail 74 is connected with the end of the longitudinal guide rail 1 close to the lane. As an extension of the longitudinal guide rail 1, when the reversing guide rail 4 is in the second state, it is movably connected to the swing guide rail 74 in the longitudinal extension state through the connection mechanism and can slide with the swing guide rail 74 under the action of the connection mechanism; in the transverse movement state, the swing guide rail 74 is perpendicular to the longitudinal guide rail 1; the transverse guide component is used to swing the guide rail 74 along a direction perpendicular to the longitudinal direction. When moving in the direction of the guide rail 1, it guides; the transverse guide component is one of the transverse guide structure 1, the transverse guide structure 2 and the transverse guide structure 3, wherein the transverse guide structure 1 includes a guide pin and a groove-shaped cavity provided on the swing guide rail 74, and the bottom surface of the groove-shaped cavity is provided with a long groove along its length direction. The guide pin is provided on the panel 73 and slides with the long groove. At this time, the inner contour of the guide rail is guided; the transverse guide structure 2 includes a plurality of guide pins provided on the panel 73, and the guide pins are distributed in two rows. The swing guide rail 74 is located between the two rows of guide pins, and the outer contour of the swing guide rail 74 is respectively guided and matched with the two rows of guide pins on both sides. At this time, it is the outer contour of the guide rail guided; the transverse guide structure 3 includes a guide sleeve provided on the panel 73 and a guide rod provided on the swing guide rail 74. The guide rod slides with the guide sleeve. At this time, it is the guide rail external component guided; when the swing guide rail 74 is in the transverse movement state, it can move in a direction perpendicular to the longitudinal guide rail 1 under the driving action of the driving mechanism and the transverse guiding action of the transverse guide component.

[0125] Furthermore, the panel 73 is rotatably mounted on the parking space 2 via a housing and a panel rotation component. Specifically, the housing is fixedly mounted below the ground, and the panel rotation component is constrained by the housing to rotate perpendicular to the ground. The panel 73 is securely mounted at the upper end of the panel rotation component, level with the ground. The panel rotation component can be a freely rotatable structure such as a bearing. The swinging guide rail 74 has the same cross-sectional shape as the longitudinal guide rail 1 and can also operate in conjunction with the guide component of the coupling mechanism. The length of the swinging guide rail 74 is greater than the required lateral displacement length of the vehicle loading plate 3. When the swinging guide rail 74 is in its longitudinally extended state, the sum of its length and the longitudinal guide rail 1's length is greater than the required longitudinal displacement length of the vehicle loading plate 3. The swinging guide rail 74 and the longitudinal guide rail 1 coincide with the centerline of the longitudinal guide rail 1. In this state, the front end of the swinging guide rail 74 is located at the rotation center of the panel 73, while the rear end is aligned with the end of the longitudinal guide rail 1, representing the extension of the longitudinal guide rail 1 toward the lane. The swinging guide rail 74 and the guide component of the coupling mechanism form a linear displacement guide pair for the vehicle loading plate.

[0126] Furthermore, based on the above structure, the connection mechanism of this embodiment includes a guide component and a clamping component. The guide component is disposed on the reversing guide rail 4 and is one of guide structure 1, guide structure 2, and guide structure 3. Guide structure 1 includes at least two rollers arranged with their rotational centerlines horizontally, which are capable of rolling engagement with the outer surface of the longitudinal guide rail 1; guide structure 2 includes at least two rollers arranged with their rotational centerlines vertically, which are capable of rolling engagement with the grooved inner surface of the longitudinal guide rail 1; and guide structure 3 includes at least two groups, each group of at least two rollers arranged with their rotational centerlines vertically, which are capable of rolling engagement with the two side surfaces of the longitudinal guide rail 1. The clamping component includes a clamping member disposed on the reversing guide rail 4 and a clamped member disposed on the swing guide rail 74. The clamping member is capable of clamping the clamped member when the reversing guide rail 4 switches between the second and third states. The longitudinal guide rail 1 is a fixed guide rail structure, disposed in the middle and rear regions of the inner edge line 24 of the parking space 2 floor, and is raised above the floor as a whole. The guide components play a guiding role by rolling engagement with the longitudinal guide rail 1. The swing rail 74 is a swingable guide rail structure and is provided at the front end area of ​​the inner side line 24 .

[0127] Furthermore, the above-mentioned guide component can also be used as a guide between the reversing guide rail 4 and the swing guide rail 74. The cross-sections of the longitudinal guide rail 1 and the swing guide rail 74 are the same. When the guide component adopts the above-mentioned guide structure one, the cross-section of the guide rail is a solid shape including an outer rectangle, an outer circle, an outer trapezoid, and an outer triangle, and the outer edge cross-sectional shape of the roller matches the cross-sectional shape above and on both sides of the longitudinal guide rail 1 and the swing guide rail 74. When the guide component adopts the above-mentioned guide structure two, the cross-section of the guide rail is an inner groove type, and the outer diameter size of the roller matches the width size of the inner groove type. When the guide component adopts the above-mentioned guide structure three, the cross-section of the guide rail is an outer rectangle, and the distance size between the two rollers in the same group matches the width size of the outer rectangle.

[0128] Furthermore, the steering mechanism is also provided with a rotation positioning mechanism, which includes a limiting component 1 and a limiting component 2. The first rotation limit position of the swinging guide rail 74 is that its center line is parallel to the inner side line 24 of the parking space 2. The limiting component 1 limits the first rotation limit position of the swinging guide rail 74 by limiting the swing angle when the swinging guide rail 74 is converted from the lateral displacement state to the longitudinal extension state; correspondingly, the second rotation limit position of the swinging guide rail 74 is the position when its center line is parallel to the lane side line after it rotates 90° following the vehicle loading plate 3. The limiting component 2 limits the second rotation limit position of the swinging guide rail 74 by limiting the swing angle when the swinging guide rail 74 is converted from the longitudinal extension state to the lateral displacement state. The above-mentioned limiting component 1 and limiting component 2 that limit the 90° rotation range of the swing guide rail 74 are both commonly used mechanisms. Since the rotation of the swing guide rail 74 has been guided by the panel 73, the limiting component 1 and limiting component 2 only need to limit the rotation position of the swing guide rail 74 to stop the rotation of the swing guide rail 74. Therefore, the limiting component 1 and limiting component 2 only need to set a position sensor or a limiting component (including a limiting block, a positioning pin) at the rotation position of the swing guide rail 74, or set a position sensor and a limiting component at the same time to meet the rotation limit requirements, which will not be introduced one by one here.

[0129] Furthermore, the steering mechanism can also be configured with a mobile clamping mechanism, which is arranged on the vehicle loading plate 3 and has two states: clamping and separation. In the clamping state, the reversing guide rail 4 is connected to the swinging guide rail 74. When the vehicle loading plate 3 makes a linear displacement, the swinging guide rail 74 follows and makes a synchronous displacement; in the separation state, the reversing guide rail 4 and the swinging guide rail 74 have no connection relationship. When the vehicle loading plate 3 makes a linear displacement, the swinging guide rail 74 is stationary. The above-mentioned mobile clamping mechanism arranged on the reversing guide rail 4 and having two states of clamping and separating for the swinging guide rail 74 is a commonly used mechanism. Since the displacement of the swinging guide rail 74 has been guided by the guide pin or guide rod, the clamping state of the mobile clamping mechanism only needs to limit the position of the swinging guide rail 74 so that when the carrier plate 3 is displaced, it can drive the swinging guide rail 74 to move synchronously. Therefore, as long as a clamped part with a solid shape (including plate-shaped, column-shaped, and groove-shaped) is provided on the swinging guide rail 74, and a clamping part with a shape matching the clamped part and capable of moving back and forth to form two states of clamping and separation is provided on the reversing guide rail 4, the needs can be met. It is a simple reciprocating linear displacement drive unit (including a linear motor, electromagnetic or motor-driven gear rack, cam, lever, hinge, etc.), which will not be introduced one by one here.

[0130] When the loading plate 3 is located in the inner area of ​​the parking space 2, the movable clamping mechanism is in the separated state, and the swing guide rail 74 is equivalent to the extension of the longitudinal track 1 in the direction of the lane. The operation process of the loading plate 3 is as follows:

[0131] 1. The driving mechanism drives the vehicle carrier 3 to perform longitudinal linear displacement under the guidance of the guide component. The guide component first passes the position of the longitudinal track 1 and then enters the position of the swing guide rail 74. Finally, the vehicle carrier 3 completely enters the lane area and the driving wheel 75 stops driving.

[0132] 2. The mobile clamping mechanism is actuated, so that the vehicle loading plate 3 is in a clamping state connected to the swing guide rail 74;

[0133] 3. The driving mechanism drives the vehicle loading plate 3 to rotate 90° toward the outside of the parking space so that the longitudinal centerline of the vehicle loading plate 3 is parallel to the centerline of the lane; during this process, the swing guide rail 74 rotates synchronously with the vehicle loading plate 3;

[0134] 4. The driving mechanism drives the vehicle loading plate 3 to perform a lateral linear displacement, away from the parking space 2, until it reaches the end of the lateral displacement. The driving mechanism stops driving, and the vehicle loading plate 3 is located at the end (end) of the lane area. During this process, the swing guide rail 74 is clamped by the movable clamping mechanism and moves synchronously with the vehicle loading plate 3.

[0135] 5. The operation process is completed.

[0136] When the vehicle loading plate 3 is located at the end position of the lane area, the mobile clamping mechanism is in a separated state. The operation process of the vehicle loading plate 3 in this solution is:

[0137] 1. The driving mechanism drives the vehicle loading plate 3 to move laterally and linearly under the guidance of the guide component and move toward the parking space 3. During this process, the swing guide rail 74 is clamped by the movable clamping mechanism and moves synchronously with the vehicle loading plate 3. When the vehicle loading plate 3 reaches the starting point of the lateral displacement, the driving mechanism stops driving.

[0138] 2. The driving mechanism rotates the vehicle loading plate 3 90° toward the inside of the parking space 2, so that the longitudinal centerline of the vehicle loading plate 3 is parallel to the centerline of the parking space 2. During this process, the swing guide rail 74 is clamped by the movable clamping mechanism and rotates synchronously with the vehicle loading plate 3. Ultimately, the centerline of the swing guide rail 74 coincides with the centerline of the longitudinal guide rail 1, which is equivalent to an extension of the longitudinal guide rail 1 toward the lane.

[0139] 3. The mobile clamping mechanism is in a state of separation without any connection with the swing guide rail 74;

[0140] 4. The driving mechanism drives the vehicle loading plate 3 to move longitudinally in a straight line under the guidance of the guide component. The guide component first passes through the position of the swing guide rail 74 and then enters the position of the longitudinal guide rail 1. Finally, the vehicle loading plate 3 is located at the end position in the inner area of ​​the parking space 2, and the driving mechanism stops driving.

[0141] 5. The operation process of the vehicle loading plate 3 is completed.

[0142] The key point of the technical solution of this embodiment is that there is no fixed guide rail on the front edge 23 of the parking space 2, but the guide rail on the inner edge 24 is divided into two sections: a fixed middle section and a rotatable front section; the rotatable section is called a swing guide rail 74, which can be used as a part of the longitudinal guide rail 1 or as a separate lateral guide rail. Figures 9 to 12 The specific example shown is used to specifically illustrate the working process and working principle of the vehicle loading plate steering mechanism 100 of this embodiment:

[0143] The driving mechanism on the vehicle loading plate 3 adopts the driving mechanism 2, and is only equipped with one driving wheel, ie, the driving wheel 75, so it is a single driving wheel form.

[0144] like Figure 9 As shown, the longitudinal guide rail 1 is arranged in the middle and rear end position of the inner side line 24 of the parking space 2, the center line of the swing guide rail 74 coincides with the center line of the longitudinal guide rail 1, the vehicle loading plate 3 is parked on the parking space 2, and the rear end is installed with roller 1 71 and roller 2 72 near the inner position, which are clamped by the inner vertical surface of the longitudinal guide rail 1, that is, the longitudinal guide rail 1 and the swing guide rail 74 are groove-type guide rails; a panel 73 is installed on the ground near the end position of the lane of the swing guide rail 74; the panel 73 is provided with a guide column hole 76.

[0145] like Figure 10As shown, the vehicle loading plate 3 is driven by the driving wheel 75 and moves longitudinally into the lane position under the clamping guidance of the longitudinal guide rail 1 and the swing guide rail 74 on the roller 1 71 and the roller 2 72 until the rotation center lines of the roller 2 72 and the guide post hole 76 coincide with each other; at this time, the roller 2 72 is driven downward as a guide post and enters the interior of the guide post hole 76, forming a fixed-point rotation mechanism.

[0146] like Figure 11 As shown, the vehicle loading plate 3 is driven by the driving wheel 75 to rotate 90° clockwise until the longitudinal center line is parallel to the lane edge line. During this period, the swing guide rail 74 is driven by roller 1 71 to rotate synchronously; finally, roller 2 72 is driven upward and exits the internal area of ​​the guide post hole 76.

[0147] like Figure 12 As shown, the carrier plate 3 is driven by the drive wheel 75 and moves laterally to the left side of the figure, guided by the swing guide 74 on rollers 1 71 and 2 72, until it reaches the end position. During this time, the lateral guide member on the panel 73 guides the swing guide 74 in lateral movement.

[0148] The reverse direction reset operation of the vehicle loading plate 3 in this embodiment can refer to the above description. Figure 12 、 Figure 11 、 Figure 10 、 Figure 9 The order of execution is not described here.

[0149] It can be seen that the vehicle loading plate steering mechanism 100 proposed in this solution realizes arc-free transition and right-angle steering of the vehicle loading plate in a simple, reliable and low-cost manner, overcoming the shortcomings of current technology. Example 4

[0150] The difference between this embodiment and the first and second embodiments is that the vehicle loading plate steering mechanism 100 proposed in this embodiment does not have an L-shaped corner structure formed by the vertical intersection of the longitudinal guide rail 1 and the transverse guide rail. In this embodiment, the longitudinal guide rail 1 extends directly to the front edge line 23. Compared with the first to third embodiments, the steering mechanism of this embodiment omits the transverse guide rail or the swing guide rail, and the structure is more simplified. Figures 13 to 16As shown, in this embodiment, the connection mechanism includes a guide component arranged on the reversing guide rail 4, and the guide component is one of the guide structure 1, the guide structure 2 and the guide structure 3, wherein the guide structure 1 includes at least two rollers with a horizontal rotation center line, and the rollers can roll with the top and both sides of the longitudinal guide rail 1; the guide structure 2 includes at least two rollers with a vertical rotation center line, and the rollers can roll with the grooved inner surface of the longitudinal guide rail 1; the guide structure 3 includes at least two groups, each group of at least two rollers with a vertical rotation center line, and the rollers can roll with the two side surfaces of the longitudinal guide rail 1; the steering mechanism includes a rotating component 1, a rotating component 2, a drive unit 1 and an avoidance gap, wherein the rotating component 1 is a cylindrical shaft arranged on the reversing guide rail 4, and the rotation center line is perpendicular to the ground, and the rotating component 2 is a component with a cylindrical inner hole, which is arranged on the ground. , and is located at the end of the longitudinal guide rail 1 close to the lane; the rotation centerline of the cylindrical inner hole is perpendicular to the ground, and when the reversing guide rail 4 is in the second state, the rotation centerline of the cylindrical inner hole coincides with the rotation centerline of the cylindrical shaft; the driving unit 1 is a reciprocating linear displacement driving mechanism. When the reversing guide rail 4 is in the second state, the driving unit 1 can drive at least one of the rotating component 2 and the rotating component 1 to rise and fall linearly, so that the cylindrical shaft and the cylindrical inner hole are converted between a combined state and a separated state, wherein, in the combined state, the cylindrical shaft is located in the cylindrical inner hole, forming a fixed-point rotation mechanism, and the reversing guide rail 4 can be converted between the second state and the third state under the driving action of the driving mechanism; in the separated state, the cylindrical shaft and the cylindrical inner hole are disengaged from each other and have no connection relationship; the avoidance notch is set on the longitudinal guide rail 1, which is used to prevent the longitudinal guide rail 1 from interfering with the guide component when it rotates following the reversing guide rail 4.

[0151] Furthermore, in this embodiment, the longitudinal guide rail 1 is positioned at the inner edge 24 of the parking space 2. It is a grooved guide rail with an upward-facing notch, raised above the ground as a whole, with its centerline parallel to the inner longitudinal edge 24 of the parking space 2. One end of the longitudinal guide rail 1 is located at the center point of rotation of the vehicle loading plate 3 at right angles, and the other end extends into the interior of the parking space 2, with a length greater than the required longitudinal displacement of the vehicle loading plate 3. The reversing guide rail 4 is positioned behind the vehicle loading plate 3, near the inner edge 24 of the parking space 2, with its centerline parallel to the longitudinal edge of the vehicle loading plate 3 and a length greater than the required lateral displacement of the vehicle loading plate 3.

[0152] In this embodiment, the steering mechanism further includes a transverse guide component, which is one of transverse guide structure 1, transverse guide structure 2, transverse guide structure 3 and transverse guide structure 4, wherein:

[0153] (1) The transverse guide structure 1 includes a groove-shaped notch provided at the bottom of the reversing guide rail 4 and a rotating component 3 for slidingly cooperating with the groove-shaped notch. The rotating component 3 is provided on the ground and is located at the end of the longitudinal guide rail 1 close to the lane, specifically at the rotation center point of the right-angle turn of the vehicle loading plate 3; the rotating component 3 is a cylinder or a rectangular body; when the reversing guide rail 4 is converted to the third state, it can move in a direction perpendicular to the longitudinal guide rail 1 under the driving action of the driving mechanism and the transverse guiding action of the transverse guide structure 1. The above-mentioned rotating component three includes at least two cylinders or at least one rectangular body, the center lines of the two cylinders are perpendicular to the ground, and the center line is parallel to the longitudinal edge line of the vehicle loading plate 3; two side surfaces of the rectangular body are perpendicular to the ground and parallel to the longitudinal edge line of the vehicle loading plate 3; when the vehicle loading plate 3 is longitudinally displaced from the parking space 2 to the lane to the end position, it rotates 90° around the above-mentioned rotation center point, and the groove-shaped notch of the reversing guide rail 4 is opposite to the cylinder of the rotating component three; when the vehicle loading plate 3 is laterally displaced, the inner groove of the reversing guide rail 4 clamps the cylinder to achieve guidance of the lateral displacement.

[0154] (2) The second transverse guide structure includes multiple cylinders, the center lines of any cylinder are perpendicular to the ground, and all cylinders are arranged in two rows. When the reversing guide rail 4 is converted to the third state, the reversing guide rail 4 is located between the two rows of cylinders, and the two sides of the reversing guide rail 4 are respectively coordinated with the two rows of cylinders. The reversing guide rail 4 can move in a direction perpendicular to the longitudinal guide rail 1 under the driving action of the driving mechanism and the transverse guiding action of the second transverse guide structure.

[0155] Specifically, the reversing guide rail 4 is a guide rail with a rectangular cross-section, and the rotating component three is at least three cylinders with a rectangular cross-section that slides together with the guide rail; the center lines of the cylinders are perpendicular to the ground and are divided into two parallel rows, and the center line of the cylinders in the same row is parallel to the longitudinal edge line of the vehicle loading plate 3, and the vertical distance between the two rows of cylinders is greater than or equal to the cross-sectional width of the reversing guide rail 4; when the vehicle loading plate 3 is longitudinally displaced from the parking space 2 to the lane to the end position, it rotates 90° around the above-mentioned rotation center point, and the rectangular cross-section of the reversing guide rail 4 is opposite to the middle position of the two rows of cylinders of the rotating component three; when the vehicle loading plate 3 is laterally displaced, the rectangular cross-section of the reversing guide rail 4 is clamped by the two rows of cylinders to achieve guidance of the lateral displacement.

[0156] (3) The transverse guide structure three includes the transverse guide structure one and the drive unit two. The drive unit two is a reciprocating linear displacement drive mechanism. When the reversing guide rail 4 is converted to the third state, the drive unit two can drive at least one of the rotating component three and the reversing guide rail 4 to rise and fall, so that the groove-shaped notch and the rotating component three are slidably matched.

[0157] Specifically, one of the reversing guide rail 4 or the rotating component three is a component that can slide up and down; the driving unit two is a reciprocating linear displacement driving mechanism. When the vehicle loading plate 3 is longitudinally displaced from the parking space 2 to the lane to the end position, it rotates 90° around the above-mentioned rotation center point position, and the driving unit two drives the up and down sliding components to move up or down. One of the displacement limit positions makes the groove-shaped notch of the reversing guide rail 4 and the cylinder or rectangular body of the rotating component three in a combined state, and the other displacement limit position makes the groove-shaped notch of the reversing guide rail 4 and the cylinder or rectangular body of the rotating component three in a separated state; the combined state refers to the inner groove of the reversing guide rail 4 clamping the cylinder or rectangular body to achieve lateral displacement guidance; the separated state refers to the inner groove of the reversing guide rail 4 being out of contact with the cylinder or rectangular body and having no connection relationship.

[0158] (4) The transverse guide structure 4 includes the transverse guide structure 2 and the drive unit 3. The drive unit 3 is a reciprocating linear displacement drive mechanism. When the reversing guide rail 4 is converted to the third state, the drive unit 3 can drive at least one of the two rows of cylinders and the reversing guide rail 4 to rise and fall, so that the reversing guide rail 4 and the two rows of cylinders can slide together.

[0159] Specifically, one of the reversing guide rail 4 or the rotating component three is a component that can slide up and down; the driving unit three is a reciprocating linear displacement driving mechanism. When the vehicle loading plate 3 is longitudinally displaced from the parking space 2 to the lane to the end position, it rotates 90° around the above-mentioned rotation center point position, and the driving unit three drives the up and down sliding components to move up or down. One of the displacement limit positions makes the rectangular cross-section of the reversing guide rail 4 fall into the middle position of the two rows of cylinders of the rotating component three, and is in a combined state, and the other displacement limit position makes the rectangular cross-section of the reversing guide rail 4 and the two rows of cylinders of the rotating component three in a separated state; the combined state means that the rectangular cross-section of the reversing guide rail 4 is clamped by the two rows of cylinders of the rotating component three to achieve lateral displacement guidance; the separated state means that the rectangular cross-section of the reversing guide rail 4 is out of contact with the two rows of cylinders of the rotating component three, and there is no connection relationship.

[0160] The aforementioned drive units 1, 2, and 3 are all common mechanisms for reciprocating linear displacement drives, such as linear motors, electromagnetic or motor-driven gear racks, cams, levers, hinges, etc., and are not introduced here one by one. Among the aforementioned transverse guide structures 1, 2, 3, and 4, transverse guide structures 1 and 2 are relatively simple, but their positioning effect is not as good as that of transverse guide structures 3 and 4.

[0161] The key point of the technical solution of this embodiment is that there is no guide rail on the front edge 23 of the parking space 2, and the reversing guide rail 4 at the rear end of the vehicle loading plate 3 serves as the transverse guide rail. Figures 13 to 16The specific example shown is used to specifically illustrate the working process and working principle of the vehicle loading plate steering mechanism 100 of this embodiment:

At this time, the roller 1 81 is just located at the avoidance notch 83 on the longitudinal guide rail 1; the guide post 1 85 and the guide post 2 86 are driven downward, level with the ground, and are in an avoidance state.

[0166] like Figure 15 As shown, the clutch 89 is in a disengaged state, the vehicle loading plate 3 is driven by the outer drive wheel 810 to rotate 90° clockwise, and the roller 1 81 is unimpededly rotated out through the avoidance gap 83 until the longitudinal center line of the vehicle loading plate 3 is parallel to the lane edge line; finally, the roller 2 82 is driven upward and exits the inner area of ​​the guide post hole 84; the guide post 1 85 and the guide post 2 86 are driven upward and enter the inner groove area of ​​the reversing guide rail 4.

[0167] like Figure 16 As shown, the clutch 89 is in the engaged state, and the carrier plate 3 is driven by the inner drive wheel 88 and the outer drive wheel 810, and is clamped and guided by the guide column 1 85 and the guide column 2 86 of the reversing guide rail 4 and displaced laterally to the left side of the figure until it reaches the end (terminal) position.

[0170] like Figures 17 to 20 As shown, the vehicle loading plate steering mechanism 100 of this embodiment has the same inventive concept as the fourth embodiment. The only difference between the fourth embodiment and the fourth embodiment is that there is no panel in the conversion mechanism, the structure is further simplified, and when the reversing guide rail 4 is in the horizontal direction, the sliding cooperation mode between the reversing guide rail 4 and the guide column in the steering mechanism is different. Figures 17 to 20 The working process and working principle of the vehicle loading plate steering mechanism 100 of this embodiment are described in detail:

[0171] The driving mechanism on the vehicle loading plate 3 adopts the driving mechanism 1 in the embodiment 1, that is, the inner side of the rear end of the vehicle loading plate 3 is provided with an inner driving wheel 97 and the outer side of the rear end is provided with an outer driving wheel 99, so the driving mechanism is a double driving wheel form.

[0172] like Figures 17 to 20 As shown, roller one 91 and roller two 92 are clamped and guided by the inner side of the longitudinal guide rail 1, so the longitudinal guide rail 1 is a groove-type guide rail with the notch upward; guide column one 95 and guide column two 96 are fixedly provided on the ground at the rotation center position of the vehicle loading plate 3, so the reversing guide rail 4 is a groove-type guide rail with the notch downward.

[0174] like Figure 18 As shown, the clutch 98 is in the engaged state, and the carrier plate 3 is driven by the inner drive wheel 97 and the outer drive wheel 99, and is longitudinally moved into the lane position under the clamping guidance of the longitudinal guide rail 1 and the reversing guide rail 4 on the roller 1 91 and the roller 2 92, until the rotation center lines of the roller 2 92 and the guide post hole 94 coincide with each other; at this time, the roller 2 92 is driven downward and enters the interior of the guide post hole 94, forming a fixed-point rotation mechanism. At this time, the roller 1 91 is just located at the avoidance notch 93 on the longitudinal guide rail 1.

[0175] like Figure 19 As shown, the clutch 98 is in a disengaged state, the vehicle loading plate 3 is driven by the outer drive wheel 99 to rotate 90° clockwise, and the roller 1 91 is unimpededly rotated out through the avoidance gap 93 until the longitudinal center line of the vehicle loading plate 3 is parallel to the lane edge line; finally, the roller 2 92 is driven upward and exits the inner area of ​​the guide post hole 94; the reversing guide rail 4 is driven downward, so that the guide post 1 95 and the guide post 2 96 enter the inner groove area of ​​the reversing guide rail 4.

[0176] like Figure 20 As shown, the clutch 89 is in the engaged state, and the carrier plate 3 is driven by the inner drive wheel 97 and the outer drive wheel 99, and is clamped and guided by the guide column 1 95 and the guide column 2 96 of the reversing guide rail 4 and displaced laterally to the left side of the figure until it reaches the end (terminal) position.
