Description

Technical Field

[0001] The present invention relates to the technical field of parking equipment, and in particular to a vehicle carrier that can move back and forth longitudinally and horizontally without turning and is used in parking equipment. Background Art

[0002] Parking equipment has been widely used in China. Some parking equipment installed in single parking spaces requires the transfer of vehicles from the parking space to the lane. For example, the "lower platform forward, rotation and lateral movement" parking equipment requires three steps of forward movement, rotation and lateral movement. The mechanism operation needs to be converted between each step. The overall operation trajectory is relatively long, the occupied lane area is wide, and the operation time is long. If a technical solution can be found to reduce the operation steps, shorten the operation trajectory, reduce the occupied lane area, and reduce the operation time, the new product will have stronger market competitiveness. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the existing technology of parking equipment with single parking spaces, such as many operating steps, long operating trajectory, wide occupied lane area and long operating time, and to provide a vehicle carrier that can travel back and forth in all directions without turning, which reduces the operating steps, shortens the operating trajectory, reduces the occupied lane area and reduces the operating time, so as to effectively improve the competitiveness of the product.

[0004] In order to solve the above problems, the present invention provides a vehicle carrier that can move back and forth between a longitudinally arranged parking space and a transversely arranged lane without steering. The vehicle carrier is characterized in that the longitudinally and transversely arranged vehicle carrier moves back and forth between a longitudinally arranged parking space and a transversely arranged lane without steering during the movement. The vehicle carrier includes: The vehicle is carried on the upper portion of the vehicle body.

[0005] A longitudinal drive assembly is arranged below the carrier body and includes at least three longitudinal rollers whose rotation tangent direction is longitudinal; at least one of the longitudinal rollers is a drive roller.

[0006] A transverse driving assembly is arranged below the carrier body and includes at least three transverse rollers whose rotation tangent direction is transverse; at least one of the transverse rollers is a driving roller.

[0007] A drive switching assembly is provided on the carrier body and includes an up and down reciprocating displacement mechanism. One extreme position of the up and down reciprocating displacement mechanism causes the longitudinal roller to contact the ground and the transverse roller to disengage from the ground, and the longitudinal drive assembly is in a working state. Another extreme position causes the transverse roller to contact the ground and the longitudinal roller to disengage from the ground, and the transverse drive assembly is in a working state.

[0008] A longitudinal guide assembly includes a longitudinal guide rail and a longitudinal positioning component; there is at least one longitudinal guide rail, which is arranged on the ground of the longitudinal edge of the parking space; there are at least two sets of longitudinal positioning components, which are arranged at positions below the vehicle body corresponding to the longitudinal guide rails.

[0009] A lateral guide assembly includes a lateral guide rail and a lateral positioning component; the lateral guide rail is at least one and is arranged on the ground at the edge of the lane; the lateral positioning component is at least two sets and is arranged at a position below the vehicle body corresponding to the lateral guide rail.

[0010] The longitudinal displacement detection component and the lateral displacement detection component are position detection components, which are respectively used to detect whether the longitudinal displacement of the vehicle carrier 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 sending element and a signal triggering element. The signal sending element and the signal triggering element are respectively arranged on the ground and on the vehicle body.

[0011] A ground warning unit, wherein the ground warning unit visibly displays the displacement trajectory of the outer contour of the vehicle carrier in the lane area or displays the area involved in the displacement movement of the vehicle carrier.

[0012] A control device is connected to the longitudinal drive component, the lateral drive component, the longitudinal displacement detection component, the lateral displacement detection component, and the ground warning unit.

[0013] The operation and coordination of the relevant components of this technical solution are described as follows: When the vehicle carrier 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 state; then it instructs the longitudinal drive component to operate, so that the vehicle carrier is guided by the longitudinal guide component and makes longitudinal displacement between the parking space and the lane; when the vehicle carrier 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.

[0014] When the vehicle carrier needs to make a lateral displacement, the control device first instructs the drive switching component to operate, so that the lateral drive component is in a working state, and then instructs the lateral drive component to operate, so that the vehicle carrier is guided by the lateral guide component and makes a lateral displacement in the lane; when the vehicle carrier 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.

[0015] Furthermore, according to the aforementioned non-steering vehicle carrier that can travel back and forth in both directions, it is characterized in that the vehicle carrier also includes a photo-taking unit, the photo-taking unit circuit is connected to the control device, is arranged above the lane, takes regular photos of the lane and sends the photo results to the control device, and the photo-taking area includes the area involved in the displacement operation of the vehicle carrier; the photo-taking unit cooperates with the ground warning unit, and any object that enters the trajectory outline or area outline displayed by the ground warning unit from the outside is considered to be an obstruction to the displacement operation of the vehicle carrier, and the control device will urgently stop the displacement operation of the vehicle carrier.

[0016] Furthermore, according to the aforementioned non-steering vehicle carrier for longitudinal and transverse movement, it is characterized in that the drive switching assembly also includes a base, which is arranged below the carrier body, and the up and down reciprocating displacement mechanism is a linear displacement mechanism, which is arranged at a position between the carrier body and the base, and includes a fixing component and a displacement component, and the fixing component and the displacement component are respectively fastened to the carrier body and the base; the linear displacement mechanism enables the carrier body and the base to be relatively displaced up and down.

[0017] Preferably, according to the aforementioned non-steering vehicle carrier capable of reciprocating in both directions, the linear displacement mechanism is directly driven: the linear displacement mechanism is a screw lift mechanism driven by a motor reducer; or a rack and pinion lift mechanism driven by a motor reducer; or a cylinder piston lift mechanism driven by a motor hydraulic pressure; or a linear motor; the linear displacement mechanism directly drives the vehicle body and the base to achieve vertical relative displacement. This solution is characterized by a relatively simple structure, but requires a relatively large vertical dimension.

[0018] Preferably, according to the aforementioned longitudinal and transverse non-steering vehicle carrier, it is characterized in that the linear displacement mechanism adopts an indirect drive form: the linear displacement mechanism includes a screw mechanism and a horizontal displacement drive mechanism.

[0019] The spiral mechanism includes a screw, a nut, a rack, and a mounting seat; the screw is arranged vertically; the nut is processed with a thread matching the screw, and the outer circumference is a cylindrical gear; the rack is arranged horizontally and meshes with the cylindrical gear; the mounting seat is processed with an inner cavity, and the screw, the nut, and the rack are arranged on the inner cavity; the ends of the mounting seat and the screw are mechanically connected to the carrier body and the base respectively.

[0020] The horizontal displacement drive mechanism is a spiral mechanism driven by a motor reducer; or, it is a gear rack mechanism driven by a motor reducer; or, it is a cylinder piston mechanism driven by motor hydraulics; or, it is a linear motor; the output end of the horizontal displacement drive mechanism is mechanically connected to one end of the rack.

[0021] The linear displacement mechanism drives the rack to linearly move through the horizontal displacement drive mechanism and indirectly drives the carrier body and the base to move up and down relative to each other through the screw mechanism. The characteristic of this solution is that the structure is relatively complex, but the required vertical dimension is relatively small.

[0022] Preferably, according to the aforementioned non-steering vehicle carrier for longitudinal and transverse movement, it is characterized in that the longitudinal drive assembly is fastened and installed below the carrier body, the transverse drive assembly is fastened and installed below the base, and the upper limit position of the up and down reciprocating displacement mechanism corresponds to the longitudinal drive assembly being in a working state; the lower limit position of the up and down reciprocating displacement mechanism corresponds to the transverse drive assembly being in a working state.

[0023] The characteristics of this solution are: a transverse drive assembly is installed under the base of the drive switching assembly, and a longitudinal drive assembly is installed under the vehicle body. When the up and down reciprocating displacement mechanism drives the base to move upward relative to the vehicle body, its extreme position causes the transverse roller of the transverse drive assembly to disengage from the ground, and the longitudinal roller of the longitudinal drive assembly to contact the ground; when the up and down reciprocating displacement mechanism drives the base to move downward relative to the vehicle body, its extreme position causes the longitudinal roller of the longitudinal drive assembly to disengage from the ground, and the transverse roller of the transverse drive assembly to contact the ground.

[0024] Preferably, according to the aforementioned non-steering vehicle carrier for longitudinal and transverse movement, it is characterized in that the transverse drive assembly is fastened and installed below the carrier body, the longitudinal drive assembly is fastened and installed below the base, and the lower limit position of the up and down reciprocating displacement mechanism corresponds to the longitudinal drive assembly being in a working state; the upper limit position of the up and down reciprocating displacement mechanism corresponds to the transverse drive assembly being in a working state.

[0025] The characteristics of this solution are as follows: a longitudinal drive assembly is installed under the base of the drive switching assembly, and a transverse drive assembly is installed under 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 assembly to break contact with the ground; the transverse roller of the transverse drive assembly contacts the ground; when the drive base of the up and down reciprocating displacement mechanism moves downward relative to the vehicle body, its extreme position causes the transverse roller of the transverse drive assembly to break contact with the ground, and the longitudinal roller of the longitudinal drive assembly contacts the ground.

[0026] Preferably, according to the aforementioned non-steering vehicle carrier that moves back and forth longitudinally and laterally, it is characterized in that the number of the longitudinal guide rails is two, which are respectively arranged on the ground of the longitudinal side lines on both sides of the parking space, and the cross section is a groove-shaped with the notch facing upwards, and the length dimension is similar to the longitudinal dimension of the parking space; the longitudinal positioning component includes two sets of rollers that match the inner cross section of the groove of the longitudinal guide rails, which are respectively arranged on the inner side of the carrier body near the parking space and corresponding to the longitudinal guide rails; the transverse guide rail is one, with the same cross-sectional shape as the longitudinal guide rail, which is arranged on the ground of the lane side line near the lane side, and the length spans the side line of the parking space near the lane side and extends at least one width dimension of the parking space in the lateral displacement direction of the vehicle carrier; the longitudinal guide rails and the transverse guide rails are in the same horizontal plane; the two sets of the longitudinal positioning components are simultaneously used as the transverse positioning components, and when the vehicle carrier is laterally displaced, the rollers of the two sets of the longitudinal positioning components are simultaneously located at the inner cross section position of the groove of the transverse guide rails.

[0027] The vehicle carrier is longitudinally displaced from the parking space, and the rollers of the two sets of the longitudinal positioning components are respectively located at the inner cross-section positions of the grooves of the two longitudinal guide rails to position the longitudinal displacement of the vehicle carrier; the vehicle carrier is longitudinally displaced to the predetermined position of the lane, and the rollers of the two sets of the longitudinal positioning components simultaneously reach the inner cross-section positions of the grooves of the transverse guide rails; the vehicle carrier is laterally displaced from the lane, and the rollers of the two sets of the longitudinal positioning components located at the inner cross-section positions of the grooves of the transverse guide rails to position the transverse displacement of the vehicle carrier.

[0028] Industry common sense tells us that: if the upper plane of the transverse guide rail is level with the ground or below the ground, the transverse guide rail will not pose an obstacle to the rollers of the longitudinal drive assembly and the transverse drive assembly during the longitudinal displacement of the vehicle carrier from the parking space to the lane; if the upper plane of the transverse guide rail is higher than the ground, a gap must be made to avoid the position where the transverse guide rail poses an obstacle to the rollers of the longitudinal drive assembly and the transverse drive assembly during the longitudinal displacement of the vehicle carrier from the parking space to the lane.

[0029] Preferably, according to the aforementioned non-steering vehicle carrier for longitudinal and transverse reciprocating movement, it is characterized in that the longitudinal guide rail is one in number and is arranged on the ground of the longitudinal edge of the parking space on the side close to the lateral displacement direction of the vehicle carrier and extends to the opposite edge of the lane, and has a cross-section of a groove with a notch facing upward; the longitudinal positioning component includes two sets of rollers that match the inner cross-section of the groove of the longitudinal guide rail and are arranged at both ends of the carrier body on the side close to the lateral displacement direction of the vehicle carrier and corresponding to the longitudinal guide rail; the transverse guide rail is two in number and has the same cross-sectional shape as the longitudinal guide rail and is arranged at the positions of the two side edges of the lane, starting from the position where the longitudinal guide rail intersects with the lane edge and extending in the lateral displacement direction of the vehicle carrier by at least the width of the parking space; the longitudinal guide rail and the transverse guide rail are in the same horizontal plane; the two sets of the longitudinal positioning components are simultaneously used as the transverse positioning components, and when the vehicle carrier is laterally displaced, the rollers of the two sets of the longitudinal positioning components are respectively located at the inner cross-sectional positions of the groove of the two transverse guide rails.

DETAILED DESCRIPTION

[0043] 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.

[0044] 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

[0045] This embodiment is a schematic diagram of the basic structure of the vehicle carrier for longitudinal and transverse reciprocating without steering of the present invention installed in a parking area with three parking spaces; the installation of a single parking space or multiple parking spaces can refer to this embodiment.

[0046] First inspect Figure 1 : The interior of the parking area 00 is divided into three parking spaces, namely parking space 1 01a, parking space 2 01b, and parking space 3 01c. A vehicle carrier 02 for carrying a vehicle is set above each parking space.

[0047] Refer to the above text and examine Figures 1 to 4In this embodiment, there are two longitudinal guide rails 52 for each parking space, which are respectively set on the ground of the longitudinal side lines on both sides of the parking space. The cross-section is a groove-shaped groove with the notch facing upward, 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, which 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, which has the same cross-sectional shape as the longitudinal guide rail 52 and is set on the ground near the lane side line on one side of the lane. The length spans the side line of the parking space near the lane 07 side and extends at least the width dimension of one parking space in the lateral displacement direction of the vehicle carrier 02 (the right side in the figure); the longitudinal guide rail 52 and the transverse guide rail 32 are in the same horizontal plane.

[0048] When the vehicle carrier 02 makes a longitudinal displacement, the rollers 51 of the two sets of longitudinal positioning components are respectively located at the groove inner cross-section positions of the two longitudinal guide rails 52 of the parking space where the vehicle carrier 02 is located, guiding the longitudinal displacement of the vehicle carrier 02.

[0049] When the vehicle carrier 02 is displaced laterally, the two sets of longitudinal positioning components are simultaneously used as transverse positioning components, and the two sets of rollers 51 are simultaneously located at the groove-shaped inner cross-section position of the transverse guide rail 32 to guide the vehicle carrier 02 to make transverse displacement.

[0050] Refer to the above text and examine Figures 1 to 4 The vehicle carrier 02 includes a carrier body, a longitudinal drive component 04 arranged below the carrier body, including at least three (four in this embodiment) longitudinal rollers 41 whose rotating tangential direction is longitudinal; at least one of the longitudinal rollers 41 is a driving roller; a transverse drive component 03 is arranged below the carrier body, including at least three (four in this embodiment) transverse rollers 31 whose rotating tangential direction is transverse; at least one of the transverse rollers 31 is a driving roller.

[0051] From the above, it can be seen that the vehicle carrier 02 includes a drive switching component arranged on the carrier body (for the sake of clarity, its specific structure is not shown in the figure), and the drive switching component includes an up and down reciprocating displacement mechanism. One extreme position of the up and down reciprocating displacement mechanism makes the longitudinal roller 41 contact with the ground and the transverse roller 31 disengage from the ground, and the longitudinal drive component 04 is in a working state. The other extreme position makes the transverse roller 31 contact with the ground and the longitudinal roller 41 disengage from the ground, and the transverse drive component 03 is in a working state.

[0052] This embodiment only involves the longitudinal and transverse non-steering displacement operation of the vehicle carrier 02 located in the parking space 3 01c. Therefore, Figures 1 to 4The longitudinal drive component 04 of the vehicle carrier 02 of the displacement parking space 1 01a and the parking space 2 01b is always in a working state (the longitudinal roller 41 is shown with a thick solid line in the figure), and the transverse drive component 03 is always in a non-working state (the transverse roller 31 is shown with a thin dotted line in the figure).

[0053] The following specifically examines vehicle 02 in parking space three 01c: like Figure 1 As shown, the longitudinal drive assembly 04 is in a working state (the longitudinal roller 41 is shown with a thick solid line in the figure); Figures 1 to 2 As shown, vehicle 02 is longitudinally displaced from parking space 3 01c to lane 07; Figure 2 It is shown that the current longitudinal drive assembly 04 is still in working state (the longitudinal roller 41 is shown with a thick solid line in the figure).

[0054] Figure 3 It shows that the current longitudinal drive component 04 has switched to the non-working state (the longitudinal roller 41 is shown with a thin dotted line in the figure), and the transverse drive component 03 has switched to the working state (the transverse roller 31 is shown with a thick solid line in the figure).

[0055] Figures 3 and 4 As shown, the vehicle carrier 02 is laterally displaced in lane 07, from a position facing parking space three 01c to a position away from parking space three 01c.

[0056] Figures 2 to 4 The warning area 08 shown in the lane is a ground warning unit (for the sake of clarity, its specific structure is not shown in the figure) which visibly displays the displacement trajectory of the outer contour of the vehicle carrier 02 in the lane 07 area or displays the area involved in the displacement of the vehicle carrier 02, so that vehicles or pedestrians can avoid it.

[0057] Vehicle 02 from Figure 4 Location returned to Figure 1 The position is the reverse operation of the above description, which will not be described here. Example 2

[0058] This embodiment is similar to the first embodiment, and is a basic structural diagram of installing the longitudinal and transverse non-steering vehicle carrier of the present invention in a parking area with three parking spaces; the installation of a single parking space or more parking spaces can refer to this embodiment.

[0059] First inspect Figure 5 : The interior of the parking area 00 is divided into three parking spaces, namely parking space 1 01a, parking space 2 01b, and parking space 3 01c. A vehicle carrier 02 for carrying a vehicle is set above each parking space.

[0060] Refer to the above text and examine Figures 5 to 8 In this embodiment, there is one longitudinal guide rail 52, which is arranged on the ground of the longitudinal edge of the parking space close to the side of the lateral displacement direction of the vehicle carrier 02 (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 and are arranged at both ends of the carrier body close to the side of the lateral displacement direction of the vehicle carrier (the right side in the figure) and corresponding to the longitudinal guide rail 52; there are two transverse guide rails 32, with the same cross-sectional shape as the longitudinal guide rail 52, and are arranged at the positions of the two side edges of the lane 07, starting from the position where the longitudinal guide rail 52 intersects with the lane edge, and extending at least the width of one parking space in the lateral displacement direction of the vehicle carrier 02 (the right side in the figure); the longitudinal guide rail 52 and the transverse guide rail 32 are in the same horizontal plane.

[0061] When the vehicle carrier 02 is displaced longitudinally, the rollers 51 of the two sets of longitudinal positioning components are simultaneously located at the groove-shaped inner cross-section position of the longitudinal guide rail 52 of the parking space where the vehicle carrier 02 is located, guiding the longitudinal displacement of the vehicle carrier 02.

[0062] When the vehicle carrier 02 is displaced laterally, the two sets of longitudinal positioning components are simultaneously used as transverse positioning components, and the two sets of rollers 51 are respectively located at the inner cross-section positions of the grooves of the two transverse guide rails 32 to guide the vehicle carrier 02 to make transverse displacement.

[0063] The components such as the longitudinal drive assembly 04 and the transverse drive assembly 03 of this embodiment and the related operating steps are similar to those of the first embodiment, and can be derived by referring to the relevant description of the first embodiment, which will not be repeated here.
