Description

Technical Field

[0001] This utility model relates to the field of parking equipment technology, specifically to a vehicle carrier that can move back and forth without steering in parking equipment. Background Technology

[0002] Parking equipment is widely used in China. Some parking equipment designed for individual parking spaces requires moving vehicles from the parking space to the driveway, such as the "lower platform forward-rotating-lateral movement" parking equipment. This requires three steps: forward movement, rotation, and lateral movement. Each step also requires a mechanism transition, resulting in a relatively long overall operating trajectory, a large area occupied by the driveway, and a long operating time. If technical solutions can be found to reduce the number of operating steps, shorten the operating trajectory, reduce the area occupied by the driveway, and reduce the operating time, the resulting new products will have stronger market competitiveness. Summary of the Invention

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects of existing parking equipment with single parking spaces, such as many operating steps, long operating trajectory, large lane occupation area and long operating time, and to provide a vehicle vehicle that can travel back and forth without steering, which reduces operating steps, shortens operating trajectory, reduces lane occupation area and reduces operating time, so as to effectively improve the competitiveness of the product.

[0004] To address the aforementioned problems, this utility model provides a vehicle that can move back and forth without steering, characterized in that "moving back and forth without steering" means that the vehicle can move back and forth between longitudinally arranged parking spaces and laterally arranged lanes without any steering action during the movement; the vehicle includes:

[0005] The vehicle body carries a vehicle on its top.

[0006] A longitudinal drive assembly is disposed below the vehicle body and includes at least three longitudinal rollers whose rotational tangential direction is longitudinal; at least one of the longitudinal rollers is a drive roller.

[0007] A lateral drive assembly is disposed below the vehicle body and includes at least three lateral rollers whose rotational tangential direction is laterally; at least one of the lateral rollers is a drive roller.

[0008] A drive switching component is disposed on the vehicle body and includes a vertical reciprocating mechanism. In one extreme position of the vertical reciprocating mechanism, the longitudinal roller is in contact with the ground and the lateral roller is out of contact with the ground, and the longitudinal drive component is in working state. In another extreme position, the lateral roller is in contact with the ground and the longitudinal roller is out of contact with the ground, and the lateral drive component is in working state.

[0009] A longitudinal guide assembly includes a longitudinal guide rail and a longitudinal positioning component; the longitudinal guide rail is at least one and is disposed on the ground along the longitudinal edge of the parking space; the longitudinal positioning component is at least two sets and is disposed below the vehicle body at a position corresponding to the longitudinal guide rail.

[0010] A lateral guidance assembly, comprising a lateral guide rail and lateral positioning components; the lateral guide rail is at least one piece, disposed on the ground at the edge of the lane; the lateral positioning components are at least two sets, disposed below the vehicle body at positions corresponding to the lateral guide rail.

[0011] The longitudinal displacement detection component and the lateral displacement detection component are position detection components, respectively used to detect whether the longitudinal displacement of the vehicle has reached a predetermined position and whether the lateral displacement has reached a predetermined position. Each set of the detection components includes a paired signal transmitting element and a signal triggering element, which are respectively set on the ground and on the vehicle body.

[0012] A control device is connected to the longitudinal drive assembly, the lateral drive assembly, the longitudinal displacement detection assembly, and the lateral displacement detection assembly via wiring.

[0013] A ground warning unit that can be visually displayed in the lane area the displacement trajectory of the vehicle's outline or the area involved in the vehicle's displacement.

[0014] The control device is connected to the longitudinal drive assembly, the lateral drive assembly, the longitudinal displacement detection assembly, the lateral displacement detection assembly, and the ground warning unit via wiring.

[0015] The operation and coordination of the relevant components in this technical solution are described below:

[0016] When a vehicle needs to make longitudinal displacement, the control device first instructs the drive switching component to operate, so that the longitudinal drive component is in working condition; then it instructs the longitudinal drive component to operate, so that the vehicle is guided by the longitudinal guide component to make longitudinal displacement between the parking space and the lane; when the vehicle reaches the predetermined position, the longitudinal displacement detection component sends a signal to the control device, and the control device instructs the longitudinal drive component to stop operating.

[0017] When a vehicle needs to make lateral displacement, the control device first instructs the drive switching component to operate, putting the lateral drive component into working condition. Then, it instructs the lateral drive component to operate, so that the vehicle is guided by the lateral guide component to make lateral displacement in the lane. When the vehicle reaches the predetermined position, the lateral displacement detection component sends a signal to the control device, and the control device instructs the lateral drive component to stop operating.

[0018] Furthermore, according to the aforementioned traversing vehicle without steering, the vehicle further includes a photographing unit connected to the control device and positioned above the lane. The photographing unit takes periodic photos of the lane and sends the results to the control device. The photographing area includes the area involved in the vehicle's movement. The photographing unit works in conjunction with the ground warning unit. Any object entering the outline of the trajectory or area displayed by the ground warning unit from the outside is considered to obstruct the vehicle's movement, and the control device will immediately stop the vehicle's movement.

[0019] Furthermore, according to the aforementioned vehicle vehicle with lateral reciprocating steering, the drive switching component further includes a base, which is disposed below the vehicle body. The vertical reciprocating displacement mechanism is a linear displacement mechanism disposed between the vehicle body and the base, and includes a fixing component and a displacement component. The fixing component and the displacement component are respectively fastened to the vehicle body and the base. The linear displacement mechanism enables the vehicle body and the base to perform vertical relative displacement.

[0020] Preferably, according to the aforementioned reciprocating, non-steering vehicle, the linear displacement mechanism is characterized by direct drive: the linear displacement mechanism is a helical lifting mechanism driven by a motor and reducer; or, a gear and rack lifting mechanism driven by a motor and reducer; or, a hydraulic cylinder piston lifting mechanism driven by a motor and hydraulically; or, a linear motor; the linear displacement mechanism directly drives the vehicle body and the base to perform vertical relative displacement. This solution is characterized by a relatively simple structure, but requires a relatively large vertical dimension.

[0021] Preferably, according to the aforementioned vehicle carrier with non-steering capability for reciprocating motion, the linear displacement mechanism is characterized by adopting an indirect drive form: the linear displacement mechanism includes a helical mechanism and a horizontal displacement drive mechanism.

[0022] The helical mechanism includes a screw, a nut, a rack, and a mounting base; the screw is vertically arranged; the nut is machined with a thread that matches the screw, and its outer circumference is a cylindrical gear; the rack is horizontally arranged and meshes with the cylindrical gear; the mounting base is machined with an inner cavity, and the screw, the nut, and the rack are arranged on the inner cavity; the ends of the mounting base and the screw are mechanically connected to the carrier body and the base, respectively.

[0023] The horizontal displacement driving mechanism is a helical mechanism driven by a motor reducer; or a gear and rack mechanism driven by a motor reducer; or a hydraulic cylinder piston mechanism driven by a motor; or a linear motor; the output end of the horizontal displacement driving mechanism is mechanically connected to one end of the rack.

[0024] The linear displacement mechanism drives the rack to move linearly via a horizontal displacement drive mechanism and indirectly drives the carrier body and the base to move vertically relative to each other via the screw mechanism. This solution is characterized by a relatively complex structure, but requires relatively small dimensions in the vertical direction.

[0025] Preferably, according to the aforementioned vehicle carrier with non-steering longitudinal and transverse reciprocating motion, the longitudinal drive component is fixedly installed below the vehicle body, the transverse drive component is fixedly installed below the base, the upper limit position of the vertical reciprocating mechanism corresponds to the longitudinal drive component being in a working state; the lower limit position of the vertical reciprocating mechanism corresponds to the transverse drive component being in a working state.

[0026] The features of this solution are as follows: a lateral drive component is installed below the base of the drive switching component, and a longitudinal drive component is installed below the vehicle body. When the vertical reciprocating mechanism drives the base to move upward relative to the vehicle body, its extreme position causes the lateral roller of the lateral drive component to disengage from the ground, while the longitudinal roller of the longitudinal drive component contacts the ground; when the vertical reciprocating mechanism drives the base to move downward relative to the vehicle body, its extreme position causes the longitudinal roller of the longitudinal drive component to disengage from the ground, while the lateral roller of the lateral drive component contacts the ground.

[0027] Preferably, according to the aforementioned vehicle carrier with lateral reciprocating motion without steering, the lateral drive component is fixedly installed below the vehicle body, the longitudinal drive component is fixedly installed below the base, the lower limit position of the vertical reciprocating mechanism corresponds to the longitudinal drive component being in working state; the upper limit position of the vertical reciprocating mechanism corresponds to the lateral drive component being in working state.

[0028] The features of this solution are as follows: a longitudinal drive component is installed below the base of the drive switching component, and a lateral drive component is installed below the vehicle body. When the drive base of the displacement mechanism moves upward relative to the vehicle body, its extreme position causes the longitudinal roller of the longitudinal drive component to disengage from the ground, while the lateral roller of the lateral drive component contacts the ground. When the drive base of the up-down reciprocating displacement mechanism moves downward relative to the vehicle body, its extreme position causes the lateral roller of the lateral drive component to disengage from the ground, while the longitudinal roller of the longitudinal drive component contacts the ground.

[0029] Preferably, according to the aforementioned vehicle carrier with lateral movement and no steering, the longitudinal guide rails are two in number, respectively disposed on the ground along the longitudinal edges of the parking space, with a notch-shaped cross-section facing upwards and a length approximately equal to the longitudinal dimension of the parking space; the longitudinal positioning components include rollers matching the inner cross-section of the longitudinal guide rails, two sets in number, respectively disposed on the vehicle body near the inner side of the parking space and corresponding to the longitudinal guide rails; the transverse guide rail is one in number, with the same cross-sectional shape as the longitudinal guide rails, disposed on the ground near the edge of the lane on one side of the lane, its length spanning the edge of the parking space near the lane and extending at least one width of the parking space in the lateral displacement direction of the vehicle carrier; the longitudinal guide rails and the transverse guide rails are on the same horizontal plane; the two sets of longitudinal positioning components simultaneously function as the transverse positioning components, and when the vehicle carrier makes a lateral displacement, the rollers of the two sets of longitudinal positioning components are simultaneously located at the inner cross-section of the transverse guide rail's groove.

[0031] As is known from industry common sense: if the upper plane of the transverse guide rail is level with or below the ground, the transverse guide rail will not obstruct the rollers of the longitudinal drive component and the transverse drive component during the longitudinal movement of the vehicle from the parking space to the lane; if the upper plane of the transverse guide rail is above the ground, the transverse guide rail must make a clearance to avoid obstructing the rollers of the longitudinal drive component and the transverse drive component during the longitudinal movement of the vehicle from the parking space to the lane.

[0032] Preferably, according to the aforementioned vehicle carrier with lateral movement and no steering, the longitudinal guide rail is one in number, located on the ground near the longitudinal edge of the parking space on the side of the vehicle carrier's lateral displacement direction and extending to the opposite edge of the lane, with a cross-section of a notch facing upwards; the longitudinal positioning component includes two sets of rollers matching the inner cross-section of the longitudinal guide rail's groove, located at both ends of the vehicle body near the side of the vehicle carrier's lateral displacement direction and corresponding to the longitudinal guide rail; the transverse guide rail is two in number, with the same cross-sectional shape as the longitudinal guide rail, located on both sides of the lane edge, starting from the intersection of the longitudinal guide rail and the lane edge, extending at least one parking space width in the lateral displacement direction of the vehicle carrier; the longitudinal guide rail and the transverse guide rail are on the same horizontal plane; the two sets of the longitudinal positioning component also function as the transverse positioning component, and when the vehicle carrier makes a lateral displacement, the rollers of the two sets of the longitudinal positioning component are respectively located at the inner cross-section of the groove of the two transverse guide rails.

[0034] As is known from industry common sense: if the upper plane of the transverse guide rail is level with or below the ground, the transverse guide rail will not obstruct the rollers of the longitudinal drive component and the transverse drive component during the longitudinal movement of the vehicle from the parking space to the lane; if the upper plane of the transverse guide rail is above the ground, the transverse guide rail must make a clearance to avoid obstructing the rollers of the longitudinal drive component and the transverse drive component during the longitudinal movement of the vehicle from the parking space to the lane.

[0035] Preferably, according to the aforementioned vehicle-mounted vehicle that can move back and forth without steering, the ground warning unit includes a plurality of light-emitting devices, which are disposed on the lane and whose positions coincide with the outermost trajectory of the vehicle-mounted vehicle's displacement, and are turned on and off by command from the control device.

The lamp is positioned above the lane and projects downwards, and is turned on and off by command from the control device. The several reflective devices are positioned above the lane, and their positions coincide with the outermost trajectory of the vehicle-mounted vehicle's displacement.

Detailed Implementation

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example 1

[0052] This embodiment is a basic structural diagram of the vehicle carrier with no steering that travels back and forth as described in this utility model, installed in a parking area with three parking spaces; the installation in a single parking space or more parking spaces can refer to this embodiment.

[0053] First, examine Figure 1 The parking section 00 is divided into three parking spaces: parking space 1 01a, parking space 2 01b, and parking space 3 01c. Each parking space is equipped with a vehicle carrier 02 to carry the vehicle.

[0054] Refer to the aforementioned text and examine Figures 1 to 4In this embodiment, each parking space has two longitudinal guide rails 52, which are respectively set on the ground on both sides of the longitudinal edge of the parking space. The cross-section is a groove with the notch facing upwards, and the length dimension is the same as the longitudinal dimension of the parking space. The longitudinal positioning component includes two sets of rollers 51 that match the inner cross-section of the groove of the longitudinal guide rail 52. They are respectively set on the inner side of the vehicle body near the parking space and corresponding to the longitudinal guide rail 52. There is one transverse guide rail 32 with the same cross-sectional shape as the longitudinal guide rail 52. It is set on the ground near the edge of the lane on the side of the lane. The length crosses the edge of the parking space near the lane 07 and extends at least one parking space width in the lateral displacement direction of the vehicle vehicle 02 (shown on the right side in the figure). The longitudinal guide rail 52 and the transverse guide rail 32 are on the same horizontal plane.

[0055] When the vehicle carrier 02 makes longitudinal displacement, the rollers 51 of the two sets of longitudinal positioning components are respectively located at the inner cross-section of the groove of the two longitudinal guide rails 52 in the parking space where the vehicle carrier 02 is located, so as to guide the longitudinal displacement of the vehicle carrier 02.

[0056] When the vehicle carrier 02 makes a lateral displacement, the two sets of longitudinal positioning components are used as lateral positioning components at the same time, and the two sets of rollers 51 are located at the inner cross section of the groove of the lateral guide rail 32 to guide the lateral displacement of the vehicle carrier 02.

[0057] Refer to the aforementioned text and examine Figures 1 to 4 The vehicle carrier 02 includes a carrier body, and a longitudinal drive assembly 04 is disposed below the carrier body, including at least three (four in this embodiment) longitudinal rollers 41 with the rotation tangent direction in the longitudinal direction; at least one of the longitudinal rollers 41 is a drive roller; the lateral drive assembly 03 is disposed below the carrier body, including at least three (four in this embodiment) lateral rollers 31 with the rotation tangent direction in the lateral direction; at least one of the lateral rollers 31 is a drive roller.

[0058] As can be seen from the foregoing, the vehicle carrier 02 includes a drive switching component (its specific structure is not shown in the figure for clarity) mounted on the vehicle body. The drive switching component includes a vertical reciprocating mechanism. At one extreme position of the vertical reciprocating mechanism, the longitudinal roller 41 is in contact with the ground and the lateral roller 31 is out of contact with the ground, and the longitudinal drive component 04 is in working condition. At the other extreme position, the lateral roller 31 is in contact with the ground and the longitudinal roller 41 is out of contact with the ground, and the lateral drive component 03 is in working condition.

[0059] This embodiment only involves the longitudinal and lateral reciprocating movement of vehicle 02 located in parking space 301c without steering displacement. Figures 1 to 4The longitudinal drive assembly 04 of the vehicle vehicle 02 in parking space 1 (01a) and parking space 2 (01b) is always in working condition (the longitudinal roller 41 is shown in the figure with a thick solid line), while the lateral drive assembly 03 is always in non-working condition (the lateral roller 31 is shown in the figure with a thin dashed line).

[0060] The following section specifically examines vehicle 02 for parking space 301c:

[0061] like Figure 1 As shown, the longitudinal drive component 04 is in operation (the longitudinal roller 41 is shown with a thick solid line in the figure).

[0062] Figures 1 to 2 As shown, vehicle 02 moves longitudinally from parking space 3 01c to lane 07; Figure 2 The display shows that the longitudinal drive component 04 is still in operation (the longitudinal roller 41 is shown as a thick solid line in the figure).

[0063] Figure 3 The display shows that the current longitudinal drive component 04 has been switched to the non-working state (the longitudinal roller 41 is shown with a thin dashed line in the figure), and the transverse drive component 03 has been switched to the working state (the transverse roller 31 is shown with a thick solid line in the figure).

[0064] Figures 3 to 4 As shown, vehicle 02 moves laterally in lane 07, from a position directly opposite parking space 3 01c to a position away from parking space 3 01c.

[0065] Figures 2 to 4 The warning area 08 shown in the lane is a ground warning unit (its specific structure is not shown in the figure for clarity). In the lane 07 area, it can be seen with the naked eye to display the displacement trajectory of the vehicle 02 or the area involved in the displacement of the vehicle 02, so that vehicles or pedestrians can take avoidance measures.

[0066] Vehicle 02 from Figure 4 Location Return to Figure 1 The position is the reverse of the above-mentioned operation, which will not be repeated here. Example 2

[0067] This embodiment is similar to Embodiment 1, and is a basic structural diagram of the vehicle carrier with no steering that travels back and forth as described in this utility model in a parking area with three parking spaces; the installation in a single parking space or more parking spaces can refer to this embodiment.

[0068] First, examine Figure 5 The parking section 00 is divided into three parking spaces: parking space 1 01a, parking space 2 01b, and parking space 3 01c. Each parking space is equipped with a vehicle carrier 02 to carry the vehicle.

[0069] Refer to the aforementioned text and examine Figures 5 to 8 In this embodiment, there is one longitudinal guide rail 52, which is set on the ground along the longitudinal edge of the parking space near the side of the vehicle 02 in the lateral displacement direction (shown as the right side in the figure) and extends to the opposite edge of the lane 07. The cross-section is a groove with the notch facing upward. The longitudinal positioning component includes two sets of rollers 51 that match the inner cross-section of the groove of the longitudinal guide rail 02. They are set at both ends of the vehicle body near the side of the vehicle 02 in the lateral displacement direction (shown as the right side in the figure) and correspond to the longitudinal guide rail 52. There are two transverse guide rails 32, which have the same cross-sectional shape as the longitudinal guide rail 52. They are set at the two side edges of the lane 07, starting from the intersection of the longitudinal guide rail 52 and the lane edge, and extend at least one parking space width in the lateral displacement direction of the vehicle 02 (shown as the right side in the figure). The longitudinal guide rail 52 and the transverse guide rail 32 are on the same horizontal plane.

[0070] When the vehicle carrier 02 makes longitudinal displacement, the rollers 51 of the two sets of longitudinal positioning components are simultaneously located at the inner cross-section of the longitudinal guide rail 52 of the vehicle carrier 02 in the parking space, so as to guide the longitudinal displacement of the vehicle carrier 02.

[0071] When the vehicle carrier 02 makes a lateral displacement, the two sets of longitudinal positioning components are used as lateral positioning components at the same time. The two sets of rollers 51 are located at the inner cross-section of the groove of the two lateral guide rails 32, respectively, to guide the lateral displacement of the vehicle carrier 02.

[0072] The components such as the longitudinal drive component 04 and the transverse drive component 03, as well as the related operating steps in this embodiment, are similar to those in Embodiment 1. They can be derived by referring to the relevant description in Embodiment 1, and will not be repeated here.
