Description

Technical Field

[0001] The present invention relates to the technical field of mechanical parking equipment, and more particularly to a driving device capable of realizing straight displacement and steering displacement of a vehicle carrying plate. Background Art

[0002] With the increase in the number of cars in my country, in order to solve the problem of insufficient parking spaces, domestic mechanical parking equipment has been widely used, including forward-moving and rotating parking equipment for car loading plates (i.e., ground-level car loading plates) and other similar types of parking equipment. The operating characteristics of these types of parking equipment are that the car loading plate moves straight from the parking space to the lane, and then rotates 90 degrees with the intersection of the car loading plate close to the lane edge and the parking space edge as the rotation center, thereby realizing the steering displacement of the car loading plate from the parking space to the lane. The current products of these types of parking equipment use a single rear drive, which has the defect of low operating efficiency. Recently, the industry has proposed some front and rear drive technical solutions, but there are shortcomings such as relatively complex structures or long drive conversion processes. Therefore, designing a car loading plate steering drive device with simple structure, low manufacturing cost and high operating efficiency is still a problem that needs to be solved by technical personnel in this field. Summary of the invention

[0003] In view of this, the present invention provides a vehicle carrier plate straight-moving and steering drive device, aiming to overcome the shortcomings of current technology and realize the straight-moving and steering displacement of the vehicle carrier plate in the parking space and lane position in a simple, reliable, efficient and low-cost manner.

[0004] In order to achieve the above object, the present invention adopts the following basic technical solutions:

[0005] The side of the parking space close to the lane is the front end, the side away from the lane is the rear end, and the rotation of the loading plate is the rotation of the loading plate.

[0006] The side where the center is located is the inner side, and the other side with a larger turning radius is described as the outer side; the vehicle loading plate is a rectangular steel member used to carry vehicles, and its maximum width dimension is larger than the width dimension of the vehicle, and its maximum length dimension is larger than the length dimension of the vehicle.

[0007] A vehicle-carrying plate straight-moving and steering drive device is characterized by comprising a rear-end drive mechanism and a front-end drive mechanism.

[0008] The rear-end driving mechanism is electrically connected to the parking equipment control device, and is arranged at the rear end position of the vehicle loading plate, and includes a rear motor reducer, a rear outer roller, and a rear inner roller; the rear motor reducer is fastened on the vehicle loading plate, and the rotation centerline of the output component of the rear motor reducer is perpendicular to the centerline of the vehicle length direction of the vehicle loading plate; the control device outputs a signal to make the motor of the rear motor reducer rotate forward or reverse or stop rotating; the projection of the rotation centerline of the rear outer roller and the rear inner roller on the ground is a straight line, and is perpendicular to the centerline of the vehicle length direction of the vehicle loading plate.

[0009] The rear end drive mechanism is arranged in one of the following two ways:

[0010] Method 1: The number of the rear motor reducer is one, and it has bidirectional output at both ends, and one of the output ends is equipped with a clutch unit, and the clutch unit is controlled by the output signal of the control device and is in a separated state or a coupled state; wherein, the outer end of the rear motor reducer close to the vehicle loading plate has no matching clutch unit, and the output component of the rear motor reducer on this side is tightly connected to the rear outer roller; the inner end close to the vehicle loading plate is equipped with a clutch unit, and the output component of the clutch unit is tightly connected to the rear inner roller.

[0011] When the carrier plate is in a straight-moving state, the clutch unit is in an engaged state, and the rotational linear speed of the rear outer roller at the position in contact with the ground is the same as the rotational linear speed of the rear inner roller at the position in contact with the ground; when the carrier plate is in a turning state, the clutch unit is in a disengaged state, and the rear inner roller is a follower roller.

[0012] Mode 2: There are two rear motor reducers, one of which has an output component that is tightly connected to the rear outer roller, and the other has an output component that is tightly connected to the rear inner roller.

[0013] When the vehicle loading plate is in a straight-moving state, the rotational linear speed of the rear outer roller at the position in contact with the ground is the same as the rotational linear speed of the rear inner roller at the position in contact with the ground;

[0014] When the vehicle loading plate is in a turning state, the rear outer roller rotates so that the rotational angular velocity of the vehicle loading plate around the rotation center is the same as the rotational angular velocity of the vehicle loading plate around the rotation center caused by the rear inner roller.

[0015] According to the above description, it can be seen that in method 1, there is only one rear motor reducer, and the structure of the rear drive mechanism is relatively simple, and the control is relatively simple; but the output shaft of the rear motor reducer of method 1 needs to be set across the vehicle loading plate. If the vehicle enters from the front end of the vehicle loading plate and exits from the rear end of the vehicle loading plate, the output shaft may cause obstacles to the driving of the wheels; in this case, it is necessary to adopt method 2. At the same time, in method 2, when the vehicle loading plate turns, the two rollers at the rear end are displaced and driven at the same time, which makes the operation more stable and efficient.

[0016] The front-end driving mechanism is arranged at the front end of the vehicle-carrying plate, and comprises a reversing unit, a straight-moving driving unit, and a steering driving unit.

[0017] The reversing unit is electrically connected to the parking equipment control device, and includes a displacement drive component and a movable plate; the displacement drive component includes a fixed part and a movable part, and the relative position of the fixed part is fixed and fixedly mounted on the vehicle loading plate; the movable part is arranged on the fixed part, and can be output by the control device. The signal is outputted by the control device to make a reciprocating displacement relative to the fixed part; the movable plate is fastened on the movable part and follows the movable part to make a reciprocating displacement relative to the fixed part; one of the displacement directions of the movable part causes the movable plate to be displaced toward the ground, and the other displacement direction causes the movable plate to be displaced away from the ground. According to the above description, it can be known that the displacement drive component is a common and simple electromechanical component, which can be realized by the reciprocating linear displacement generated by electromagnetic drive or electric cylinder drive, electric hydraulic cylinder drive, or by mechanical transmission to drive the cam to rotate back and forth or the gear rack to reciprocate linear displacement or the spiral mechanism to reciprocate linear displacement; these are all conventional technologies and will not be elaborated here.

[0018] The installation positions of the straight driving unit and the steering driving unit are in one of the following two ways:

[0019] Mode 1: The straight driving unit is installed on the vehicle-carrying plate; the steering driving unit is installed on the movable plate of the reversing unit;

[0020] Mode 2: The steering drive unit is installed on the vehicle-carrying plate; the straight-moving drive unit is installed on the movable plate of the reversing unit.

[0021] It is common sense to know that no matter which of the above two methods is adopted for the installation position of the straight driving unit and the steering driving unit, the two extreme positions of the displacement of the movable plate of the displacement driving component of the reversing unit will enable the straight driving unit and the steering driving unit to switch between the two states of being relatively close to the ground and being relatively away from the ground.

[0022] The straight driving unit is electrically connected to the parking equipment control device, and includes a front motor reducer, a front outer roller, and a front inner roller; the rotation centerline of the output component of the front motor reducer is perpendicular to the centerline of the vehicle length direction of the vehicle loading plate; the control device outputs a signal to make the motor of the front motor reducer rotate forward or reverse or stop rotating; the rotation centerlines of the front inner roller and the front outer roller are perpendicular to the centerline of the vehicle length direction of the vehicle loading plate. Unlike the aforementioned rear inner roller and rear outer roller, whose rotation centerlines are defined to be perpendicular to the centerline of the vehicle length direction of the vehicle loading plate and whose projection on the ground is defined to be a straight line, the front inner roller and the front outer roller only have the limitation that their rotation centerlines are perpendicular to the centerline of the vehicle length direction of the vehicle loading plate; the reason for this is that the rear inner roller and the rear outer roller are in contact with the ground when the vehicle loading plate is moving straight or turning, which limits the projection of the rotation centerlines of the rear inner roller and the rear outer roller on the ground to be a straight line.

[0023] This ensures that the rotation of the rear inner roller and the rear outer roller will not interfere when the carrier plate turns; and the front inner roller and the front outer roller do not contact the ground when the carrier plate turns, so there is no need to limit whether the projection of the rotation center line on the ground is a straight line.

[0024] The front outer roller is fastened and installed through a bearing seat, arranged at the outer end close to the vehicle loading plate, and fastened and connected to the output component of the front motor reducer; the front inner roller is fastened and installed through a bearing seat, arranged at the front end of the vehicle loading plate close to the inner end, and fastened and connected to the output component of the front motor reducer.

[0025] The front motor reducer is set in one of the following two ways:

[0026] Mode 1: The number of the front motor reducer is one, and it is bidirectional output, wherein the output component at one end is tightly connected to the front outer roller, and the output component at the other end is tightly connected to the front inner roller;

[0027] Mode 2: There are two front motor reducers, one of which has an output component that is tightly connected to the front outer roller, and the other has an output component that is tightly connected to the front inner roller.

[0028] The rotation direction of the front outer roller and the front inner roller is the same as that of the rear outer roller, and the rotational linear speed in contact with the ground is the same as that of the rear outer roller in contact with the ground. The above constraints enable the front drive mechanism and the rear drive mechanism to jointly drive the vehicle loading plate to move in a straight line when the front outer roller and the front inner roller are in contact with the ground.

[0029] The steering drive unit is electrically connected to the parking equipment control device, and includes a steering motor reducer and a steering roller; the control device outputs a signal to make the motor of the steering motor reducer rotate forward or reverse or stop rotating.

[0030] The intersection of the projection of the extended line of the rotation center line of the output component of the steering motor reducer on the ground and the projection of the extended line of the rotation center line of the rear outer roller and the rear inner roller on the ground is located on the line passing through the rotation center of the vehicle carrier plate and parallel to the center line of the vehicle length direction.

[0031] The steering roller is fixedly installed through a bearing seat and is fixedly connected to the output component of the steering motor reducer;

[0032] When the vehicle carrier is in a steering state, the rotation direction of the steering roller is the same as that of the rear outer roller, and the steering roller rotates so that the angular velocity of the vehicle carrier about the rotation center is the same as that of the rear outer roller. The above constraints enable the front-end drive mechanism and the rear-end drive mechanism to jointly drive the vehicle carrier to perform a rotational displacement when the steering roller is in a state of contacting the ground.

[0033] When the vehicle loading plate is stationary in the internal parking space of the parking equipment, it needs to be moved toward the lane. The specific steps are as follows:

[0034] Step 01: If the rear-end drive mechanism is set up in method 1, the parking equipment control device outputs a signal so that the clutch unit of the rear-end drive mechanism is in a engaged state.

[0035] Step 02: The parking equipment control device outputs a signal to activate the displacement drive component of the reversing unit of the front drive mechanism, so that the movable plate moves to a position where the front outer roller and the front inner roller contact the ground and the steering roller leaves the ground.

[0036] Step 03: The parking equipment control device outputs a signal to cause the rear motor reducer of the rear-end drive mechanism to run forward, and at the same time causes the front motor reducer of the front-end drive mechanism to run forward. The front-end drive mechanism and the rear-end drive mechanism jointly drive the vehicle carrier to move straight in the direction of the lane.

[0037] Step 04: The vehicle loading plate is moved into place, and the parking equipment control device outputs a signal to stop the rear motor reducer of the rear-end driving mechanism, and at the same time stops the front motor reducer of the front-end driving mechanism, and the vehicle loading plate remains stationary in the lane position.

[0038] When the vehicle loading platform is stationary in the lane, it needs to make a 90° turn close to the lane edge. The specific steps are as follows:

[0039] Step 11: If the rear-end drive mechanism is set in the first manner, the parking equipment control device outputs a signal to put the clutch unit of the rear-end drive mechanism in a disengaged state.

[0040] Step 12: The parking equipment control device outputs a signal to activate the displacement drive component of the reversing unit of the front drive mechanism, so that the movable plate is displaced to a position where the steering roller contacts the ground and the front outer roller and the front inner roller leave the ground.

[0041] Step 13: The parking equipment control device outputs a signal to cause the rear motor reducer of the rear-end drive mechanism to run forward, and at the same time causes the steering motor reducer of the front-end drive mechanism to run forward. The front-end drive mechanism and the rear-end drive mechanism jointly drive the vehicle loading plate to a 90° steering displacement close to the lane edge.

[0042] Step 14: When the vehicle loading plate is turned into position, the parking equipment control device outputs a signal to stop the rear motor reducer of the rear-end driving mechanism, and at the same time stops the steering motor reducer of the front-end driving mechanism, and the vehicle loading plate is stationary near the lane edge.

[0043] The specific steps of the vehicle carrier plate making a 90° turning displacement in the opposite direction from a stationary position close to the lane edge line and the specific steps of the vehicle carrier plate moving straight in the opposite direction from a stationary position in the lane can be simply derived from the above description and will not be repeated here.

[0044] Further, according to the basic technical scheme of the above-mentioned vehicle-carrying plate straight-moving and steering drive device, it is characterized in that: the steering motor reducer of the steering drive unit is replaced by a gear transmission pair driven by the front motor reducer of the straight-moving drive unit; specifically: the number of the front motor reducer is one, with output at both ends, and the output components at both ends respectively drive a sprocket chain transmission pair; the output shafts of the two sprocket chain transmission pairs are respectively tightly connected to the front outer roller and the front inner roller; the output shaft of one of the sprocket chain transmission pairs is installed with a driving gear of the gear transmission pair near the middle end position; the driven gear of the gear transmission pair is tightly connected to the steering roller, and the steering roller is installed on the movable plate of the reversing unit through a bearing seat;

[0045] The reversing unit adopts a hinge structure, with the output shaft of the sprocket chain transmission pair installed with the gear transmission pair as the hinge shaft, and the movable plate can rotate around the hinge shaft; under the drive of the displacement driving component of the reversing unit, the movable plate makes a reciprocating swing displacement around the hinge shaft; one displacement direction makes the movable plate displace in the direction close to the ground, and the other displacement direction makes the movable plate displace in the direction away from the ground. In this technical solution, a gear transmission pair (which can be a spiral gear transmission pair or a bevel gear transmission pair) replaces the reversing motor reducer, and the reciprocating linear displacement generated by electromagnetic drive or electric cylinder drive or electric hydraulic cylinder drive makes the movable plate installed with the steering roller make a reciprocating swing displacement around the output shaft of the sprocket chain transmission pair, or the reciprocating linear displacement of the gear rack or the reciprocating linear displacement of the spiral mechanism makes the movable plate installed with the steering roller make a reciprocating swing displacement around the output shaft of the sprocket chain transmission pair through mechanical transmission. The reversing unit of this solution adopts a hinge structure to ensure that the gear transmission pair is always in an effective and correct meshing state when the movable plate is reciprocatingly swinging.

[0046] Further, according to the basic technical scheme of the above-mentioned vehicle-carrying plate straight-moving and steering drive device, it is characterized in that: the steering motor reducer of the steering drive unit is replaced by a universal coupling driven by the front motor reducer of the straight-moving drive unit; specifically: the number of the front motor reducer is one, with output at both ends, and the output components at both ends respectively drive a sprocket chain transmission pair; the output shafts of the two sprocket chain transmission pairs are respectively tightly connected to the front outer roller and the front inner roller; a universal coupling is installed at the end position near the middle of the output shaft of one of the sprocket chain transmission pairs; the other end of the universal coupling is tightly connected to the steering roller, and the steering roller is installed on the movable plate of the reversing unit through a bearing seat;

[0047] The reversing unit adopts a hinge structure, with the output shaft of the sprocket chain transmission pair equipped with the universal coupling as the hinge shaft, and the movable plate can rotate around the hinge shaft; under the drive of the displacement driving component of the reversing unit, the movable plate makes a reciprocating swing displacement around the hinge shaft; one displacement direction makes the movable plate displace in the direction close to the ground, and the other displacement direction makes the movable plate displace in the direction away from the ground. This technical solution replaces the reversing motor reducer with a universal coupling, and the reciprocating linear displacement generated by electromagnetic drive or electric cylinder drive or electric hydraulic cylinder drive makes the movable plate equipped with the steering roller make a reciprocating swing displacement around the output shaft of the sprocket chain transmission pair, or the reciprocating linear displacement of the gear rack or the reciprocating linear displacement of the spiral mechanism makes the movable plate equipped with the steering roller make a reciprocating swing displacement around the output shaft of the sprocket chain transmission pair through mechanical transmission. The reversing unit of this solution adopts a hinge structure to ensure that the universal coupling is always in an effective and correct connection state when the movable plate is reciprocatingly swinging.

[0048] The technical solution of the present invention solves the defects of existing products, and the main difference from the prior art is that the rear-end drive mechanism provides more structural options; the front-end drive mechanism realizes the switching between straight-moving drive and turning drive through a reversing unit with a simple structure, and provides different structural options; different structural options of the rear-end drive mechanism and the front-end drive mechanism can produce a variety of combinations; the most important thing is that the rear-end drive mechanism and the front-end drive mechanism can obtain the common drive of the vehicle carrier whether it is moving straight or turning, which greatly improves the stability and efficiency of the operation, and has a simple structure and low production cost.

DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0055] Figures 1 to 4 FIG. 1 is a schematic diagram of the operation of one embodiment of the present invention.

[0056] First investigate Figure 1 . As can be seen in the figure, the vehicle loading plate 02 is currently stationary inside the parking space 01, and the front of the figure is the lane 04, and the edge of the lane 04 close to the parking space 01 is the lane edge 04a, and the intersection of the lane edge 04a and the right edge of the parking space 01 is the rotation center 03 of the vehicle loading plate 02; therefore, the upper part of the vehicle loading plate 02 in the figure is the rear end, the lower part is the front end, the right side is the inner side, and the left side is the outer side. As can be seen in the figure, the rear end of the vehicle loading plate 02 is provided with a rear drive device (only the rear inner roller 06a and the rear outer roller 06b are shown in the figure); the front end of the vehicle loading plate 02 is provided with a front drive device (only the steering roller 05, the front inner roller 07a; the front outer roller 07b are shown in the figure).

[0057] As can be seen from the figure, the projection of the rotation center line of the rear outer roller 06b and the rear inner roller 06a on the ground is a straight line, and is perpendicular to the center line of the vehicle length direction of the vehicle loading plate 02; the rotation center line of the front inner roller 07a and the front outer roller 07b is perpendicular to the center line of the vehicle length direction of the vehicle loading plate 02; the intersection of the projection of the extended line of the rotation center line of the steering roller 05 on the ground and the projection of the extended line of the rotation center line of the rear inner roller 06a and the rear outer roller 06b on the ground is located on the line passing through the rotation center 03 of the vehicle loading plate 02 and parallel to the center line in the vehicle length direction.

[0058] Since the current running trend of the vehicle carrier 02 can only be a straight-ahead displacement in the direction of the lane, the steering roller 05 in the figure is drawn with a dotted line, indicating that the steering roller 05 is currently driven by the reversing unit and is off the ground and out of contact with the ground; the front inner roller 07a and the front outer roller 07b are currently in contact with the ground, so they are drawn with a solid line; the rear inner roller 06a and the rear outer roller 06b are always in contact with the ground, so they are drawn with a solid line.

[0059] Figure 2 Display, vehicle carrier plate 02 Figure 1 On the basis of this, the parking equipment control device outputs a signal to make the rear motor reducer of the rear-end driving mechanism run forward, and at the same time makes the front motor reducer of the front-end driving mechanism run forward, and the front-end driving mechanism and the rear-end driving mechanism jointly drive the vehicle loading plate 02 to move straight in the direction of lane 04; in this process, the linear speeds of the front inner roller 07a, the front outer roller 07b, the rear inner roller 06a, and the rear outer roller 06b in contact with the ground are the same. Figure 2 As shown, the vehicle loading plate 02 has completely entered the area of ​​the lane 04 , and the projection of the extension line of the rotation center line of the rear inner roller 06 a and the rear outer roller 06 b on the ground just passes through the rotation center 03 of the vehicle loading plate 02 .

[0060] Figure 3 Display, vehicle carrier plate 02 Figure 2 Based on the above, the parking equipment control device outputs a signal to cause the displacement driving component of the reversing unit of the front drive mechanism to operate, so that the movable plate is displaced to the position where the steering roller 05 contacts the ground and the front outer roller 07b and the front inner roller 07a leave the ground. Therefore, the steering roller 05 in the figure is drawn with a solid line, indicating that the steering roller 05 is currently driven by the reversing unit to contact the ground; the front inner roller 07a and the front outer roller 07b have already left the ground and have no contact with the ground, so they are drawn with dotted lines; the rear inner roller 06a and the rear outer roller 06b are always in contact with the ground, so they are drawn with solid lines.

[0061] Then, the parking equipment control device outputs a signal to make the rear motor reducer of the rear-end drive mechanism run forward, and at the same time makes the steering motor reducer of the front-end drive mechanism run forward. The front-end drive mechanism and the rear-end drive mechanism jointly drive the vehicle loading plate to a 90° turning displacement close to the lane edge 04a.

[0062] Figure 4 It shows that the vehicle loading plate 02 has been turned into position and is stationary near the lane edge 04a.

[0063] Figure 5 , which is a schematic diagram of the structure of the front drive device in another embodiment of the present invention; this embodiment corresponds to the first improved scheme mentioned above, and the steering motor reducer is replaced by a gear rotation pair.

[0064] As can be seen from the figure, there is only one front motor reducer 08, with output at both ends, wherein the output component at the right end of the figure drives a sprocket chain transmission pair consisting of a sprocket 09a, a sprocket 09b, and a chain 09c, the output shaft of which is a transmission shaft 13c, which is firmly connected to the front inner roller 07a, and the transmission shaft 13c is disposed on the carrier plate 02 by bearing seats 13a and 13b; the output component at the left end of the front motor reducer 08 drives a sprocket chain transmission pair consisting of a sprocket 10a, a sprocket 10b, and a chain 10c, the output shaft of which is a transmission shaft 12b, which is firmly connected to the front outer roller 07b, and the transmission shaft 12b is disposed on the carrier plate 02 by bearing seats 12a and 12c.

[0065] As can be seen in the figure, the driving gear (bevel gear 14a) of the gear transmission pair is installed at the right end of the transmission shaft 12b of the sprocket chain transmission pair on the left, and the passive gear (bevel gear 14a) of the gear transmission pair is fastened to the steering roller 05 through the transmission shaft 15c. The steering roller 05 is installed on the movable plate (not shown in the figure) of the reversing unit through the bearing seats 15a and 15b.

[0066] As can be seen from the foregoing, the reversing unit of the present scheme adopts a hinge structure, with the transmission shaft 12b of the sprocket chain transmission pair equipped with a gear transmission pair as the hinge axis, and the movable plate can rotate around the hinge axis; under the drive of the displacement driving component of the reversing unit, the movable plate makes a reciprocating swing displacement around the hinge axis; one of the displacement directions causes the movable plate to displace toward the ground (so that the steering roller 05 contacts the ground, and the front inner roller 07a and the front outer roller 07b leave the ground), and the other displacement direction causes the movable plate to displace away from the ground (so that the steering roller 05 leaves the ground, and the front inner roller 07a and the front outer roller 07b contact the ground).

[0067] The aforementioned second improvement scheme (i.e., the scheme using a universal joint) can be clearly understood with reference to the above description and will not be elaborated here.

[0068] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
