Description

Technical Field

[0001] This application relates to the field of automated parking garage technology, and in particular to a vehicle-carrying device and automated parking equipment. Background Technology

[0002] With the rapid development of the automobile industry and the continuous improvement of residents' living standards, social problems such as traffic congestion and parking difficulties have become increasingly prominent. Due to factors such as scarce land resources, outdated planning standards for existing parking facilities, and unsatisfactory returns on parking lot investments, the domestic parking industry has developed relatively slowly, with the growth rate of parking space supply far lower than the growth rate of demand. Parking difficulties have become a long-standing problem in cities.

[0003] On the one hand, the continued high growth in the number of motor vehicles has created a huge demand for parking spaces; on the other hand, constrained by factors such as rigid land resource limitations, outdated parking space allocation standards, low investment returns, and complex project approval processes, the supply of parking spaces is severely insufficient, and the problem of urban parking difficulties remains difficult to alleviate. Against this backdrop, multi-level parking garages have shown many advantages over traditional parking lots and are gradually becoming an effective alternative to traditional parking facilities.

[0004] Chinese invention patent CN118008025A discloses a wide-inner-width automatic centering lifting and lateral moving parking device, comprising: a frame assembly having a receiving space; at least one vehicle carrier plate disposed within the receiving space for carrying a vehicle, the vehicle carrier plate having a vehicle receiving area; a first vehicle moving assembly and a second vehicle moving assembly, both disposed within the vehicle carrier plate and arranged along the length of the vehicle carrier plate, one for adjusting the front wheels and the other for adjusting the rear wheels, thereby causing the vehicle to be adjusted into the vehicle receiving area by rotating the corresponding wheels; a photoelectric monitoring assembly disposed on the vehicle carrier plate for monitoring the vehicle's posture through photoelectric signals; and a controller electrically connected to the first vehicle moving assembly, the photoelectric monitoring assembly, and the second vehicle moving assembly.

[0005] Although the aforementioned lifting and traversing parking equipment can align and correct vehicles on the vehicle platform, the large weight of the vehicles and their direct placement on the top surface of the platform cause sliding friction between the wheels and the top surface of the platform. This results in the first and second vehicle moving components needing to output a large driving force to move the vehicles, increasing the power and strength requirements of the first and second vehicle moving components, and thus increasing energy consumption. Summary of the Invention

[0006] This application provides a vehicle-carrying device and a three-dimensional parking system to solve the problems existing in related technologies. The technical solution is as follows: In a first aspect, embodiments of this application provide a vehicle-mounted device, including: Car platform; Multiple first positioning rollers are arranged sequentially along the width direction and rotatably mounted on the vehicle platform. The rotation center line of each first positioning roller is parallel to the length direction of the vehicle platform. Multiple second positioning rollers are arranged sequentially along the width direction and rotatably mounted on the vehicle platform. The rotation center line of each second positioning roller is parallel to the length direction of the vehicle platform. The multiple second positioning rollers and the multiple first positioning rollers are spaced apart along the length direction to form positioning grooves. The positioning grooves are used to cooperate with the rear wheels of the vehicle to support and position the rear wheels of the vehicle. A drive mechanism is mounted on the vehicle platform and has a first output end and a second output end. The first output end and the second output end move linearly along the width direction, and the movement directions of the first output end and the second output end are opposite.

It is connected to the second output end so that the second pushing component can move along the width direction to abut against the inner side of the front wheel and the inner side of the rear wheel on the second side of the vehicle.

[0007] In one embodiment, the vehicle-mounted device further includes: A limiting component is disposed on the top surface of the vehicle carrier plate. The limiting component is used to abut against the rear wheel of the vehicle to restrict the rear wheel of the vehicle within the positioning groove.

[0008] In one embodiment, the limiting component is provided with a limiting inclined surface, which is inclined backward in the direction away from the second positioning roller, and the limiting inclined surface is used to abut against the rear wheel of the vehicle.

[0009] In one embodiment, the top of the first positioning roller and the top of the second positioning roller are both at a height higher than the top surface of the vehicle platform.

[0010] In one embodiment, the cross-section of the positioning groove gradually increases from bottom to top along the width direction.

[0011] In one embodiment, the first positioning roller has a first positioning slope on the side facing the second positioning roller, and the second positioning roller has a second positioning slope on the side facing the first positioning roller, the second positioning slope and the first positioning slope forming the positioning groove.

[0012] In one embodiment, the vehicle-mounted device further includes: The mounting base is disposed on the vehicle platform and supports the plurality of first positioning rollers and the plurality of second positioning rollers.

[0013] In one embodiment, the drive mechanism includes: An electric motor, wherein the electric motor is disposed within the vehicle platform; A gear, which is sleeved on the output shaft of the motor and can rotate with the output shaft of the motor; A first rack, movably disposed within the vehicle platform along the width direction, meshes with the gear, and has a first output end; and The second rack is movably disposed within the vehicle platform along the width direction, the second rack meshes with the gear, and the second rack is provided with the second output end.

[0014] In one embodiment, the top surface of the vehicle platform has two receiving cavities, which are respectively located on both sides of the first pushing member and the second pushing member along the width direction. Each receiving cavity is provided with the plurality of first positioning rollers and the plurality of second positioning rollers. And / or, the number of the drive mechanisms is two sets, and the two sets of drive mechanisms are arranged at intervals along the length direction; And / or, the first pushing component includes a first connecting plate and a first pushing plate, both of which extend along the length direction. The first connecting plate is connected to the first output end, and the first pushing plate is vertically disposed on one side of the first connecting plate along the width direction. The first pushing plate is used to abut against the inner side of the front wheel and the inner side of the rear wheel on the first side of the vehicle. The second pusher component includes a second connecting plate and a second pusher plate. Both the second connecting plate and the second pusher plate extend along the length direction. The second connecting plate is connected to the second output end. The second pusher plate is vertically disposed on one side of the second connecting plate along the width direction. The second pusher plate is used to abut against the inner side of the front wheel and the inner side of the rear wheel on the second side of the vehicle.

[0015] Secondly, embodiments of this application provide a multi-level parking system, including: The main framework; and In the aforementioned vehicle-carrying device, the vehicle-carrying plate is movably mounted on the main frame body.

[0016] The advantages or beneficial effects of the above technical solutions include at least the following: In the vehicle-carrying device of the present invention, when a vehicle enters the vehicle-carrying platform, the two rear wheels of the vehicle respectively fall into the corresponding positioning grooves, so that the two rear wheels of the vehicle are supported and positioned by the first positioning roller and the second positioning roller respectively. If the vehicle is not in the center position of the vehicle-carrying platform, the drive mechanism can be operated to move the first output end and the second output end of the drive mechanism in the opposite direction along the width direction of the vehicle-carrying platform, so as to drive the first pushing component and the second pushing component to move in the opposite direction synchronously. At this time, one of the first pushing component and the second pushing component will abut against the inner side of the front wheel and the inner side of the rear wheel on one side of the vehicle, pushing the vehicle towards the center position of the vehicle-carrying platform. When the first pushing component and the second pushing component abut against the inner side of the front wheel and the inner side of the rear wheel on both sides of the vehicle at the same time, it indicates that the vehicle is in the center position of the vehicle-carrying platform, thereby realizing the function of perfect vehicle centering. During this process, since the two rear wheels of the vehicle are supported by the rotatable first positioning roller and the rotatable second positioning roller, when the two rear wheels of the vehicle move along the width direction of the vehicle platform under the pushing action, the two rear wheels of the vehicle can roll smoothly under the low resistance support of the first positioning roller and the second positioning roller. Since the rolling friction resistance is much smaller than the sliding friction resistance, the two rear wheels of the vehicle can move easily under the pushing force, making the vehicle move easily as a whole. This can greatly reduce the power and strength requirements of the drive mechanism, thereby reducing overall energy consumption and lowering overall operating costs.

[0021] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0022] See Figures 1-9 This illustration shows a vehicle-mounted device according to a preferred embodiment of the present invention, comprising: Carrier plate 1; Multiple first positioning rollers 2 are arranged sequentially along the width direction and rotatably mounted on the vehicle platform 1. The rotation center line of each first positioning roller 2 is parallel to the length direction of the vehicle platform 1. Multiple second positioning rollers 3 are arranged sequentially along the width direction and rotatably mounted on the vehicle platform 1. The rotation center line of each second positioning roller 3 is parallel to the length direction of the vehicle platform 1. The multiple second positioning rollers 3 and multiple first positioning rollers 2 are spaced apart along the length direction to form positioning grooves 4. The positioning grooves 4 are used to cooperate with the corresponding rear wheels of the vehicle (of course, in actual applications, they can also cooperate with the corresponding front wheels of the vehicle) to support and position the rear wheels of the vehicle. The drive mechanism 5 is mounted on the vehicle platform 1. The drive mechanism 5 has a first output end and a second output end. The first output end and the second output end move linearly along the width direction, and the movement directions of the first output end and the second output end are opposite. A first pushing member 6 extends along its length and is connected to a first output end to allow it to move along its width. The first pushing member 6 is used to abut against the inner sides of the front and rear wheels on a first side of the vehicle. The second pushing component 7 extends along the length direction and is spaced apart from the first pushing component 6 along the width direction. The second pushing component 7 is connected to the second output end so that the second pushing component 7 can move along the width direction, thereby moving the second pushing component 7 away from or closer to the first pushing component 6. The second pushing component 7 is used to abut against the inner side of the front wheel and the inner side of the rear wheel on the second side of the vehicle.

[0023] In the vehicle-carrying device of the present invention, when a vehicle enters the vehicle-carrying platform 1, the two rear wheels of the vehicle respectively fall into the corresponding positioning grooves 4, so that the two rear wheels of the vehicle are supported and positioned by the first positioning roller 2 and the second positioning roller 3 respectively. If the vehicle is not in the center position of the vehicle-carrying platform 1, the drive mechanism 5 can be operated to move the first output end and the second output end of the drive mechanism 5 in the opposite direction along the width direction of the vehicle-carrying platform 1, so as to drive the first pushing component 6 and the second pushing component 7 to move in the opposite direction synchronously. At this time, one of the first pushing component 6 and the second pushing component 7 will abut against the inner side of the front wheel and the inner side of the rear wheel on one side of the vehicle, pushing the vehicle towards the center position of the vehicle-carrying platform 1. When the first pushing component 6 and the second pushing component 7 abut against the inner side of the front wheel and the inner side of the rear wheel on both sides of the vehicle at the same time, it indicates that the vehicle is in the center position of the vehicle-carrying platform 1, thereby realizing the vehicle's complete centering function. During this process, since the two rear wheels of the vehicle are supported by the rotatable first positioning roller 2 and the rotatable second positioning roller 3, when the two rear wheels of the vehicle move along the width direction of the vehicle platform 1 under the pushing action, the two rear wheels of the vehicle can roll smoothly under the low resistance support of the first positioning roller 2 and the second positioning roller 3. Since the rolling friction resistance is much smaller than the sliding friction resistance, the two rear wheels of the vehicle can easily move under the pushing force, making the vehicle move easily as a whole. This can greatly reduce the power and strength requirements of the drive mechanism 5, thereby reducing the overall energy consumption and lowering the overall operating cost.

[0024] It is understandable that the first pushing component 6 and the second pushing component 7 are centrally symmetrical and have the same length along the width direction.

[0025] It is understood that the vehicle-mounted device of the present invention may also be configured with: A photoelectric detector (not shown in the figure) is installed on the vehicle carrier plate 1 and is used to detect the attitude of the vehicle on the vehicle carrier plate 1. A controller (not shown in the figure) is electrically connected to the drive mechanism 5 and the photoelectric detector. The controller controls the drive mechanism 5 to perform preset actions based on feedback information from the photoelectric detector. For example, when the photoelectric detector detects that the vehicle is not in a centered position, the controller activates the drive mechanism 5 based on this feedback, driving the first pushing component 6 and the second pushing component 7 to move in opposite directions. During the centering adjustment process, if only one pushing component is in contact with the inner side of the front wheel and the inner side of the rear wheel on the same side of the vehicle, the drive mechanism 5 outputs a small pushing force. The controller detects that the current of the motor 51 of the drive mechanism 5 is small (the required pushing force is small, so the current of the motor 51 is small), and the controller determines that the centering adjustment is still in progress. If the first pushing component 6 and the second pushing component 7 simultaneously contact the inner sides of the front wheel and the inner side of the rear wheel on both sides of the vehicle, the vehicle is already in a centered position and cannot move further. At this time, the load on the motor 51 of the drive mechanism 5 increases, and the drive mechanism 5 outputs a larger pushing force. After detecting the increased current, the controller determines that the centering adjustment is complete and controls the drive mechanism 5 to shut down to avoid excessive pushing or energy waste.

[0026] See Figure 1 It is understood that the first pushing member 6 is provided with a set of roller assemblies on the side away from the second pushing member 7 along the width direction. The roller assembly includes the aforementioned multiple first positioning rollers 2 and multiple second positioning rollers 3 to support and position one of the rear wheels of the vehicle. The second pushing member 7 is provided with another set of roller assemblies on the side away from the first pushing member 6 along the width direction. The roller assembly includes the aforementioned multiple first positioning rollers 2 and multiple second positioning rollers 3 to support and position the other rear wheel of the vehicle.

[0027] See Figure 1 and Figure 5 In one embodiment, the top surface of the vehicle carrier plate 1 has two receiving cavities 11, which are respectively located on both sides of the first pushing member 6 and the second pushing member 7 along the width direction. Each receiving cavity 11 is provided with multiple first positioning rollers 2 and multiple second positioning rollers 3. Thus, the first positioning rollers 2 and second positioning rollers 3 are not directly installed on the top surface of the vehicle carrier plate 1, but are embedded in the corresponding receiving cavity 11 of the vehicle carrier plate 1. The receiving cavity 11 is recessed downward relative to the top surface of the vehicle carrier plate 1, thereby reducing the overall protrusion height of the first positioning rollers 2 and second positioning rollers 3, and preventing the tops of the first positioning rollers 2 and second positioning rollers 3 from being much higher than the top surface of the vehicle carrier plate 1. As a result, the rear wheels of the vehicle only need to overcome a small obstacle height when entering the positioning groove 4, thus enabling them to enter the positioning groove 4 more smoothly and easily, reducing the risk of impact and jamming.

[0028] See Figures 4-5 In one embodiment, the vehicle-mounted device further includes: The limiting component 8 is located on the top surface of the vehicle carrier plate 1. The limiting component 8 is used to abut against the rear wheels of the vehicle to restrict the rear wheels of the vehicle within the positioning groove 4. This not only prevents the vehicle from accidentally slipping on the vehicle carrier plate 1 and ensures parking safety, but also ensures that the rear wheels of the vehicle always maintain the correct fit with the positioning groove 4, so that the rear wheels of the vehicle maintain effective fit with the first positioning roller 2 and the second positioning roller 3. As a result, during the vehicle centering adjustment process, the movement of the rear wheels of the vehicle is smoother, the required thrust is smaller, and the overall adjustment process is more labor-saving.

[0029] See Figure 5 In one embodiment, the limiting component 8 is provided with a limiting ramp 81, which is inclined backward in a direction away from the second positioning roller 3. The limiting ramp 81 is used to abut against the rear wheel of the vehicle. By abutting against the rear wheel of the vehicle with the limiting ramp 81, the vehicle can be effectively prevented from accidentally sliding backward in the length direction of the vehicle platform 1. At the same time, the limiting ramp 81 is inclined backward in a direction away from the second positioning roller 3, so that when the first pushing component 6 or the second pushing component 7 drives the vehicle to make lateral centering adjustments, the rear wheel and the limiting ramp 81 make smooth contact, and the limiting ramp 81 will not generate excessive lateral resistance, thereby not affecting the smooth movement of the rear wheel on the first positioning roller 2 and the second positioning roller 3.

[0030] See Figure 5 In one embodiment, the top of the first positioning roller 2 and the top of the second positioning roller 3 are both at a height higher than the top surface of the vehicle platform 1, that is, the top of the first positioning roller 2 and the top of the second positioning roller 3 both protrude slightly from the top surface of the vehicle platform 1.

[0031] See Figure 5 In one embodiment, the cross-section of the positioning groove 4 gradually increases from bottom to top along the width direction, that is, the positioning groove 4 is a tapered structure that is narrow at the bottom and wide at the top. The inclined surfaces on both sides of the positioning groove 4 can form a close fit constraint with the tire sidewall of the rear wheel of the vehicle, thereby reliably limiting the rear wheel to a predetermined position within the positioning groove 4. At the same time, the longitudinal resistance generated by the inclined surfaces on both sides of the positioning groove 4 on the rear wheel effectively prevents the vehicle from accidentally slipping along the length direction.

[0032] Specifically, see Figure 5 In one embodiment, the first positioning roller 2 has a first positioning inclined surface 21 on the side facing the second positioning roller 3, and the second positioning roller 3 has a second positioning inclined surface 31 on the side facing the first positioning roller 2. The second positioning inclined surface 31 and the first positioning inclined surface 21 form a positioning groove 4.

[0033] See Figure 5 In one embodiment, the vehicle-mounted device further includes: Mounting base 9 is located on the vehicle platform 1 and is specifically installed in the receiving cavity 11. Mounting base 9 carries multiple first positioning rollers 2 and multiple second positioning rollers 3 to connect the first positioning rollers 2 and the second positioning rollers 3 to form a modular structure for easy installation.

[0034] See Figure 3 , Figures 5-9 In one embodiment, the drive mechanism 5 includes: Motor 51, motor 51 is located inside the vehicle platform 1; Gear 52 is sleeved on the output shaft of motor 51 and can rotate with the output shaft of motor 51. A first rack 53 is movably disposed within the vehicle platform 1 along its width direction. The first rack 53 meshes with a gear 52, and the first rack 53 has a first output end. The second rack 54 is movably disposed within the vehicle carrier plate 1 along its width direction. The second rack 54 meshes with the gear 52 and has a second output end. Thus, the motor 51 drives the gear 52 to rotate, causing the first rack 53 and the second rack 54 to move in opposite directions, thereby causing the first pushing component 6 and the second pushing component 7 to move in opposite directions. This causes the first pushing component 6 and the second pushing component 7 to move away from each other to push the front and rear wheels of the vehicle, or to move the first pushing component 6 and the second pushing component 7 closer together to reset.

[0035] Of course, in other embodiments, a lead screw and nut pair can be used instead of the gear and rack mechanism, as long as it can drive the first pushing component 6 and the second pushing component 7 to move in opposite directions.

[0036] See Figure 9 There are two sets of drive mechanisms 5, which are arranged at intervals along the length direction. In this way, by driving the first jacking component 6 and the second jacking component 7 simultaneously by the two sets of drive mechanisms 5, the movement of the first jacking component 6 and the second jacking component 7 can be smoother and more stable. This makes the force on the vehicle uniform during the lateral movement, and will not cause deflection or jamming, which is beneficial to improving the accuracy of vehicle centering.

[0037] See Figure 3 The first pushing component 6 includes a first connecting plate 61 and a first pushing plate 62. Both the first connecting plate 61 and the first pushing plate 62 extend along the length direction. The first connecting plate 61 is connected to the first output end to realize the first pushing component 6 and the first output end are stably connected together. The first pushing plate 62 is vertically arranged on one side of the first connecting plate 61 along the width direction. The first pushing plate 62 is used to abut against the inner side of the front wheel and the inner side of the rear wheel on the first side of the vehicle to increase the contact area between the first pushing component 6 and the wheel, prevent slippage and failure, and thus improve the pushing stability. Similarly, the second jacking component 7 includes a second connecting plate 71 and a second jacking plate 72. Both the second connecting plate 71 and the second jacking plate 72 extend along the length direction. The second connecting plate 71 is connected to the second output end to achieve a stable connection between the second jacking component 7 and the second output end. The second jacking plate 72 is vertically mounted on one side of the second connecting plate 71 along the width direction. The second jacking plate 72 is used to abut against the inner side of the front wheel and the inner side of the rear wheel on the second side of the vehicle to increase the contact area between the second jacking component 7 and the wheel, prevent slippage and failure, and thus improve jacking stability.

[0038] Specifically, the first push plate 62 can be fixedly connected to the first output end by fasteners (such as bolts, rivets, etc.) or by welding.

[0039] Similarly, the second push plate 72 can be fixedly connected to the second output end by fasteners (such as bolts, rivets, etc.) or by welding.

[0040] See Figure 10 In one embodiment, the vehicle-mounted device further includes: Overweight detection device 10 is located at the front of the vehicle platform 1 along the length direction, and is electrically connected to the controller. An extra-long detection device 20 is installed above the vehicle platform 1 and is electrically connected to the controller. An over-width detection device 30 is located above the vehicle platform 1 and is electrically connected to the controller. An over-height detection device is installed above the vehicle platform 1 and is electrically connected to the controller. The over-limit alarm 60 is electrically connected to the controller. The controller is used to control the over-limit alarm 60 to perform an alarm action based on the over-limit feedback information from any one of the overweight detection device 10, overlength detection device 20, overwidth detection device 30, and overheight detection device, so as to promptly remind the vehicle that it exceeds the limit and prevent it from parking beyond the limit.

[0041] In practical applications, when a vehicle enters the vehicle platform 1, two of the vehicle's tires first press against the overweight detection device 10, recording a set of weight data. As the vehicle continues to enter the vehicle platform 1, the other two tires press against the overweight detection device 10, recording another set of data. The controller adds up the two sets of data to obtain the total weight of the vehicle. If the total weight exceeds the set value, the overweight alarm 60 will sound an alarm, indicating that the vehicle is overweight.

[0042] In practical applications, the overlength detection device 20, the overwidth detection device 30, and the overheight detection device are all composed of a transmitter and a receiver. They emit light from one end and receive light from the other. If the light is blocked, the over-limit alarm 60 will sound an alarm, indicating that the vehicle exceeds the limit (overlength, overwidth, or overheight). This device is used to detect whether parked vehicles exceed the limit.

[0043] See Figure 10 In one embodiment, the vehicle-mounted device further includes: The charging device 40 is mounted on the vehicle carrier plate 1 and is electrically connected to the controller. Thus, after the vehicle is parked, if charging is required, the charging gun at the rear of the vehicle carrier plate 1 is inserted into the vehicle's charging port to begin charging. The charging device 40 and all power units can be powered by external accompanying cables.

[0044] See Figures 10-11 This invention illustrates a preferred embodiment of a multi-level parking system, comprising: The main frame 50; and The aforementioned vehicle carrier device has a vehicle carrier plate 1 that is movably mounted on the frame body 50.

[0045] The three-dimensional parking equipment of the present invention, by employing the aforementioned vehicle-carrying device, ensures that when a vehicle enters the vehicle-carrying platform 1, the two rear wheels of the vehicle fall into the corresponding positioning grooves 4, so that the two rear wheels of the vehicle are supported and positioned by the first positioning roller 2 and the second positioning roller 3 respectively. If the vehicle is not in the center position of the vehicle-carrying platform 1, the drive mechanism 5 can be operated to move the first output end and the second output end of the drive mechanism 5 in the opposite direction along the width direction of the vehicle-carrying platform 1, so as to drive the first pushing component 6 and the second pushing component 7 to move in the opposite direction synchronously. At this time, one of the first pushing component 6 and the second pushing component 7 will abut against the inner side of the front wheel and the inner side of the rear wheel on one side of the vehicle, pushing the vehicle towards the center position of the vehicle-carrying platform 1. When the first pushing component 6 and the second pushing component 7 abut against the inner side of the front wheel and the inner side of the rear wheel on both sides of the vehicle at the same time, it indicates that the vehicle is in the center position of the vehicle-carrying platform 1, thereby realizing the function of complete vehicle centering. During this process, since the two rear wheels of the vehicle are supported by the rotatable first positioning roller 2 and the rotatable second positioning roller 3, when the two rear wheels of the vehicle move along the width direction of the vehicle platform 1 under the pushing action, the two rear wheels of the vehicle can roll smoothly under the low resistance support of the first positioning roller 2 and the second positioning roller 3. Since the rolling friction resistance is much smaller than the sliding friction resistance, the two rear wheels of the vehicle can easily move under the pushing force, making the vehicle move easily as a whole. This can greatly reduce the power and strength requirements of the drive mechanism 5, thereby reducing the overall energy consumption and lowering the overall operating cost.

[0046] It is understandable that multi-level parking systems also include: The transverse drive mechanism 5 is connected to the vehicle platform 1 at its output end to drive the vehicle platform 1 to move laterally, so as to make way for the lifting channel. The lifting drive mechanism 5 has its output end connected to the vehicle platform 1 to drive the vehicle platform 1 to move vertically, facilitating vehicle entry and exit.
