Description

Technical Field

[0001] The invention relates to a three-dimensional garage. Background Art

[0002] In conventional multi-story parking garages and car wash areas, both are independently set up, which increases the occupied area of ​​the site. How to achieve vehicle cleaning during vehicle transportation (driving the vehicle to perform movements such as lifting, translation, and stopping) to save time and land has become an urgent problem that our researchers need to solve.

[0003] In addition, the traditional parking method of the three-dimensional garage is to drive the vehicle into the lifting area by yourself or park the vehicle in the transfer area, and then use the vehicle picking mechanism to drag the vehicle into the lifting area and finally store the vehicle;

[0004] However, during the parking process, you will face the following problems:

[0005] 1. Since the conventional vehicle pickup mechanism can move in a straight line or in a curve, when the vehicle is parked crookedly in the transfer area or the lifting area, the linear motion vehicle pickup mechanism cannot accurately locate the vehicle for pickup. The curved motion vehicle pickup mechanism must first accurately locate the vehicle before picking it up, which takes a long time to pick up the vehicle and is inefficient.

[0006] 2. Since the wheelbase of the vehicle will change, that is, the parking position of the vehicle parked in a transfer area of ​​a certain area will change, and the lifting device will cause uneven force on both sides of the lifting plate during the lifting process of the vehicle.

[0007] In summary, how to achieve differentiated parking and retrieval in the garage (i.e., correcting the angles of vehicles with different wheelbases during the parking process and simultaneously retrieval of multiple vehicles at different positions) and improve the parking and retrieval efficiency has become an urgent problem that our researchers need to solve. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0009] The present invention is a three-dimensional parking garage, comprising: a berthing area, which is suitable for parking vehicles; a lifting area, on which a transport mechanism is arranged, and the transport mechanism is suitable for driving the vehicle to do lifting and lowering movement along the height direction of the berthing area; a transfer area, which is suitable for parking vehicles to be stored and retrieved; a vehicle cleaning device, which is arranged in the transport mechanism and is suitable for cleaning the vehicle; a differentiated access device, which is arranged in the transport mechanism and is suitable for transporting the vehicle in the transfer area to the transport mechanism while correcting the parking angle of the vehicle, and then cooperating with the transport mechanism to transport the vehicle to the berthing area for parking or is suitable for transporting the vehicle in the berthing area to the transport mechanism, and then cooperating with the transport mechanism to transport the vehicle to the transfer area for retrieval;

[0010] In this solution, the berth area can adopt a multi-story parking platform; the lifting area adopts a handling mechanism to lift the vehicle; the transfer area is used to park the vehicles to be stored and retrieved; usually one or both sides of the bottom of the multi-story parking platform are used as the transfer area.

[0011] The vehicle cleaning equipment can clean the vehicle while it is being transported, thus saving time; the differentiated storage and access equipment can correct the angle of vehicles parked in the transfer area, as well as realize forward or backward storage and access for multiple vehicles on the same parking platform.

[0012] In order to illustrate the specific structure of the vehicle washing device, the vehicle washing device used in the present invention includes a lifting frame, which is suitable for lifting and lowering along the height direction of the vehicle; it includes lifting components located on the left and right sides of the vehicle, and translation components located on the front and rear sides of the vehicle;

[0013] The lifting frame is composed of a lifting component and a translation component. In this solution, two lifting components and two translation components are provided;

[0014] The translation component is suitable for moving closer to or farther from the front and rear sides of the vehicle; that is, within the lifting frame, the translation component can move along the length direction of the vehicle;

[0015] A cleaning brush set, which is arranged in the lifting component or the translation component and is suitable for synchronously approaching or moving away from the midpoint direction of the lifting component or the translation component; a brush, which is arranged on the cleaning brush set;

[0016] When the vehicle is stored in the handling area, the brushes on the cleaning brush set will be driven to fit the vehicle surface according to the vehicle wheelbase, and the lifting frame will drive the brushes to descend or ascend;

[0017] The lifting component and the translation component serve as supports, and multiple cleaning brush groups are arranged therein. The cleaning brush groups can make translational movements toward the midpoints of the lifting component and the translation component inside the lifting component and the translation component. That is to say, the cleaning brush groups on both sides can gather toward the midpoints of the lifting component and the translation component, so that the total length of the multiple cleaning brush groups can be adjusted, the lengths of the multiple cleaning brush groups can be matched with the length and width of the vehicle, the brushes can be fitted to the surface of the vehicle, and the lifting frame can drive the brushes to descend or ascend to achieve vehicle cleaning.

[0018] It should be noted here that when the vehicle is entering the warehouse, the lifting frame is located at the top to prevent it from interfering with the vehicle's entry; the basic information of the vehicle (such as length, width, height, wheelbase, weight, etc.) can be known through the license plate scanning device before entering the warehouse.

[0019] How to realize the lifting movement of the lifting frame, the present invention adopts a lifting frame connected with a vertically arranged screw through a screw nut; a motor drives multiple screws to rotate synchronously through the connection between a synchronous shaft and a steering gear.

[0020] The lifting and lowering movement of the lifting frame is achieved by the rotation of the lead screw driven by the motor, thereby realizing the lifting and lowering of the lead screw nut on the lead screw, and then realizing the lifting and lowering of the lifting frame on the lead screw; during the lifting process, only one motor is used, and the synchronous rotation of multiple lead screws is achieved through the cooperation of the synchronous shaft and the steering gear, so that the lifting frame is always in a horizontal state during the lifting process.

[0021] In order to prevent the lifting frame from deflecting during movement, the present invention adopts a guide rod fixedly arranged parallel to the screw rod, and the guide rod passes through the translation component;

[0022] The guide rod is parallel to the lead screw, and limits the lifting frame to only perform lifting movement during its movement.

[0023] In order to illustrate the specific structure of the cleaning brush set, the present invention adopts a cleaning brush set comprising: a first structure and / or a second structure; wherein the second structure is located on both sides of the plurality of first structures;

[0024] In the present embodiment, the cleaning brush group adopts the first structure or the second structure alone, or in combination. If the first structure is used alone, the structure is not compact enough; if the second structure is used alone, the number of components increases, which increases the cost. Therefore, it is preferred to adopt a combination of the first structure and the second structure, and the first structure is symmetrically arranged on both sides of the multiple second structures.

[0025] The first structure includes a first connecting rod, one end of which is connected to a brush; a second connecting rod, which is symmetrically arranged relative to the first connecting rod, one end of the second connecting rod is hinged to the first connecting rod, and the other end is connected to the brush; a hydraulic cylinder, whose cylinder body is fixedly connected to the first connecting rod, and its piston rod is arranged upward or downward; a third connecting rod, which is symmetrically arranged, one end of which is hinged to the piston rod of the hydraulic cylinder, and the other end is hinged to the corresponding second connecting rod;

[0026] The second structure includes a first connecting rod, one end of which is connected to a brush; a second connecting rod, one end of which is hinged to one side of the first connecting rod and the other end of which is connected to a brush; a hydraulic cylinder, a cylinder body of which is fixedly connected to the first connecting rod and the piston rod of which is arranged upward or downward; a third connecting rod, one end of which is hinged to the piston rod of the hydraulic cylinder and the other end of which is hinged to the second connecting rod;

[0027] Left and right screw rods are arranged parallel to the length direction of the lifting component or the translation component; the left and right screw rods are arranged in pairs and can be located at the top or bottom of the lifting component or the translation component; the left and right screw rods are both rotatably connected to multiple first connecting rods.

[0028] When the left and right screw rods rotate, the first connecting rod is driven to move toward the midpoint of the lifting component or the translation component, which drives the brush to be squeezed, reduces the angle formed by the second connecting rod and the hydraulic cylinder piston rod, and extends the piston rod of the hydraulic cylinder; when the left and right screw rods are reversed, the first connecting rod is driven to move away from the midpoint of the lifting component, the hydraulic cylinder piston rod is reset, and the angle formed by the second connecting rod and the hydraulic cylinder piston rod is expanded, so that the brush is restored to its original state.

[0029] That is to say, when the overall length of the cleaning brush group needs to be shortened, the left and right screws rotate to drive the brushes to be squeezed, and the brush located at the end of the second connecting rod moves downward in line with the contour of the brush on the first connecting rod, thereby matching the overall length of the cleaning brush group with the length of the vehicle; in this process, the number of brushes in a certain area is squeezed and increased, thereby improving the cleaning efficiency.

[0030] The hydraulic cylinder plays a resetting role, and the piston rod of the hydraulic cylinder is in an extended state when the overall length of the cleaning brush group is shortened; when the overall length of the cleaning brush group is restored to the original length, the piston rod of the hydraulic cylinder retracts, thereby placing the multiple brushes on the cleaning brush group in a horizontal state.

[0031] How to realize the rotation of two left and right screw rods, the present invention adopts the method of connecting the ends of the left and right screw rods to the second motor through the second synchronous rod; the second motor is suitable for driving the left and right screw rods to rotate synchronously;

[0032] Only one second motor is provided, and the synchronization of the rotation of the two left and right screw rods is achieved through the connection of the second synchronization rod.

[0033] In order to illustrate the specific structure of the brush, the present invention adopts a brush comprising a housing; an annular brush head, which is rotatably arranged in the housing; a third motor, which is fixed to the housing and is suitable for driving the annular brush head to rotate; a spray head, which sprays cleaning liquid obliquely from the center of the annular brush head to the annular brush head;

[0034] The function of the shell is to prevent the annular brush head from deforming during the extrusion process, thereby affecting its cleaning efficiency, and to collect water mist; the annular brush head is controlled to rotate by a third motor; in addition, the nozzle in this solution sprays the cleaning liquid onto the annular brush head instead of directly onto the outer surface of the vehicle. The advantage of this is that it can reduce water splashing and save water resources.

[0035] In order to dry the vehicle after washing, the present invention adopts a brush which also includes an air outlet device, in which the shell is sleeved, and the air outlet of the air outlet device is ring-shaped and faces the vehicle.

[0036] In this solution, the air outlet of the air outlet device faces the vehicle surface. During the vehicle cleaning process, air is blown onto the surface to accelerate the volatilization of moisture. The air outlet is annular, and when it fits against the vehicle surface, it forms an enclosed space to prevent water mist from splashing.

[0037] In summary, the vehicle cleaning equipment in the present multi-story garage adjusts the length of the cleaning brush group to adapt to the overall length of the vehicle, fits the brush to the surface of the vehicle, and cleans the entire vehicle through the lifting and lowering movement of the lifting frame; by adding the above-mentioned vehicle cleaning equipment to the multi-story garage, the vehicle can be cleaned during the process of vehicle transportation (driving the vehicle to lift, move, stop, etc.), so this design can reduce the footprint and improve efficiency.

[0038] To illustrate the specific structure of the differentiated access device, the differentiated access device adopted by the present invention includes at least one group of trailer frames, on which at least one pair of running wheels is fixed; a traction mechanism, which is suitable for driving the trailer frame to move forward or backward along its length direction; a tire gripping mechanism, which is arranged on the inner side or outer side of the trailer frame and is suitable for clamping and lifting the corresponding tires of the vehicle; a posture control mechanism, which is suitable for controlling the synchronous deflection of the trailer frame so that the length direction of the trailer frame is parallel to the length direction of the vehicle; when the vehicle is placed in the transfer area and needs to be parked, the posture control mechanism adjusts the angle of the trailer frame so that the length direction of the trailer frame is parallel to the length direction of the vehicle; the traction mechanism drives the trailer frame to move forward and places the trailer frame on both sides of the bottom of the vehicle, and the tire gripping mechanism moves to the side of the tire along the length direction of the trailer frame according to the wheelbase of the vehicle and then works to lift the vehicle; the traction mechanism drives the trailer frame back to its position, places the vehicle in a parking space, and corrects the angle of the trailer frame at the same time. When a vehicle needs to be picked up, the traction mechanism drives the trailer frame to move forward or / and backward synchronously, and after the vehicle placed on the parking space is clamped and lifted by the tire gripping mechanism, the traction mechanism drives the vehicle to the transfer area;

[0039] In this scheme, the trailer frame is driven by the traction mechanism and moves forward or backward through the running wheels; the trailer frame moves forward or backward to pick up the vehicle, and moves backward or forward to store the vehicle; when the trailer frame moves to both sides of the bottom of the vehicle, the tire gripping mechanism works to lift the tires, thereby lifting the entire vehicle; when the vehicle is parked at an angle, before the trailer frame moves, the posture control mechanism adjusts the offset angle of the trailer frame to align it with the length direction of the vehicle, and then the trailer frame moves;

[0040] In addition, the device can be provided with multiple sets of traction mechanisms, trailer frames, and posture control mechanisms, so as to realize the storage and retrieval of multiple vehicles; when multiple vehicles stop in the transfer area, the device can drive the vehicles to move forward or backward after the angle is corrected and then store them in the corresponding parking spaces. The principle of the vehicle retrieval method is consistent with that of the vehicle storage method. Since the vehicles parked in the parking spaces are already in the state of angle correction, the posture control mechanism does not need to be used in the vehicle retrieval process;

[0041] This device can achieve 1. simultaneous angle correction of vehicles with different wheelbases during parking; 2. simultaneous storage and retrieval of different vehicles at different positions; thus achieving differentiated storage and retrieval of vehicles by this device.

[0042] In order to illustrate the specific structure of the traction mechanism, the present invention adopts a traction mechanism including a first sliding mechanism and a second sliding mechanism arranged up and down; a partition is arranged between the first sliding mechanism and the second sliding mechanism, and a bottom plate is arranged at the bottom of the second sliding mechanism; the first sliding mechanism includes: a first rack, which is parallel to the length direction of the trailer frame and fixed to the bottom of the trailer frame; a first slide rail, which is parallel to the first rack and fixed to the upper end surface of the partition; a first slider, which is arranged at the bottom of the trailer frame and cooperates with the first slide rail; a first gear, which is arranged at the front side of the trailer frame and cooperates with the first rack to drive the trailer frame to move forward; the second sliding mechanism includes: a second rack, which is parallel to the length direction of the trailer frame and fixed to the lower end surface of the partition; a second slide rail, which is parallel to the second rack and fixed to the upper end surface of the bottom plate; a second slider, which is arranged at the bottom of the partition and cooperates with the second slide rail; a second gear, which is arranged at the rear side of the trailer frame and cooperates with the second rack to drive the trailer frame connected to the partition to move backward.

[0043] The first sliding mechanism and the second sliding machine structure are arranged up and down, the first sliding mechanism drives the trailer frame to move forward, and the second sliding machine structure drives the trailer frame to move backward, that is, the travel of the device is 3 times the length of the trailer frame;

[0044] The first sliding mechanism and the second sliding mechanism are both realized by gears and racks, and the slide block and the slide rail play a guiding and supporting role.

[0045] In order to illustrate the specific structure of the tire gripping mechanism, the tire gripping mechanism adopted by the present invention includes: two lifting rods, one end of which is hinged to the accommodating cavity on the inner side or the outer side of the trailer frame, and the other end is provided with a wheel; two first connecting rods, one end of which is hinged to the corresponding lifting rods; a second connecting rod, one end of which is hinged to the other end of the first connecting rod; a hydraulic cylinder, the piston rod of which is fixedly connected to the midpoint of the second connecting rod; when the piston rod of the hydraulic cylinder is extended, the first and second connecting rods move, driving the angle between the two lifting rods to decrease, placing the tire on the lifting rod, and lifting the vehicle;

[0046] The lifting rod is normally stored in the accommodating cavity. When work is required, the hydraulic cylinder drives the angle between the two lifting rods to decrease. Since the surface of the lifting rod is arc-shaped, it is tangent to the surface of the tire, so that the tire can be lifted;

[0047] In this solution, the wheels play the role of movement and support, and universal wheels are preferred.

[0048] When facing vehicles of different lengths, the positions of their tires will change. How to realize that the tire-grabbing mechanism can adapt to vehicles of different lengths? The present invention adopts a tire-grabbing mechanism placed in a receiving cavity on the inner side or outer side of the trailer frame; a third slide rail parallel to the length direction of the trailer frame is arranged in the receiving cavity; a third slider matched with the third slide rail is arranged on the tire-grabbing mechanism; a screw rod is rotatably arranged in the receiving cavity, and the screw rod passes through the third slider; when the screw rod rotates, the tire-grabbing mechanism moves in the receiving cavity along the direction of the third slide rail;

[0049] That is to say, the tire-grabbing mechanism realizes movement relative to the length direction of the trailer frame through the rotation of the screw rod, thereby moving the tire-grabbing mechanism to one side of the tire; the cooperation of the slider and the slide rail also plays a supporting and guiding role.

[0050] To illustrate the specific structure of the posture control mechanism, the posture control mechanism adopted by the present invention includes: a rod body, which is rotatably connected to the middle part of the trailer frame; a fourth rack, whose two ends are respectively hinged to the ends of the trailer frame; a fourth gear; which is meshed with the fourth rack; when the fourth gear rotates, the fourth rack performs translational motion, driving the trailer frame to rotate around the rod body;

[0051] Since the trailer frames can only move along their length direction, when the trailer frame rotates, the trailer frame can also rotate synchronously;

[0052] The rod body is hinged to the trailer frame, so the trailer frame can rotate around the rod body. The fourth gear, as a power source, meshes with the fourth rack, driving the fourth rack to move perpendicular to the length direction of the trailer frame. When the fourth rack is working, the angle between the fourth rack and the trailer frame bracket is not a right angle. At this time, the trailer frame rotates around the rod body so that it is parallel to the length direction of the vehicle.

[0053] In summary, the differentiated storage and retrieval equipment in the present multi-story parking garage realizes the forward and backward movement of the trailer frame through the traction mechanism, thereby realizing the storage and retrieval of the vehicle, lifts the vehicle through the tire gripping device, and corrects the offset angle of the vehicle when entering the garage through the posture control mechanism; in addition, the present equipment can realize the storage and retrieval of multiple different vehicles at different positions at the same time, saving the time for storage and retrieval and improving the efficiency of storage and retrieval.

[0054] To illustrate the specific structure of the transport mechanism, the transport mechanism of the present invention includes: a garage frame; a parking plate, which is arranged in the garage frame and on which a vehicle washing device and a differentiated access device are arranged; a power mechanism, which is fixed on the top of the garage frame; a traction rope, one end of which is connected to the parking plate, and the other end of which is connected to the output end of the power mechanism by passing through a sprocket fixed on the top of the garage frame;

[0055] The parking plate is provided with the above-mentioned vehicle cleaning equipment and differentiated access equipment; the parking plate realizes lifting and lowering movement relative to the garage frame through a power mechanism and a traction rope.

[0056] To specifically describe the power mechanism, the power mechanism of the present invention includes two lifting hydraulic cylinder groups that are arranged in an alternating manner and are in different planes up and down; each lifting hydraulic cylinder group includes two lifting hydraulic cylinders, wherein the piston rods of the two lifting hydraulic cylinders move in opposite directions; the traction rope is wound around the piston rod of one lifting hydraulic cylinder, and its end is fixed to the piston rod of the other lifting hydraulic cylinder;

[0057] There are four lifting hydraulic cylinders, two in a group, and the piston rods of every two lifting hydraulic cylinders can move in opposite directions. Four traction ropes are also set accordingly. The traction rope is wound around one of the piston rods and fixed to the other piston rod; in this way, the rising or falling distance of the parking plate can reach twice the elongation of the piston rod, ensuring the stroke of the parking plate.

[0058] Similarly, the telescopic movement of the piston rod of the lifting hydraulic cylinder can be replaced by the cooperation of the second screw rod and the second screw rod nut.

[0059] The beneficial effects of the present invention are as follows: the present invention is a garage, which uses a vehicle cleaning device to clean the vehicle while it is moving in the lifting area, saving time; through the cooperation of differentiated storage and retrieval equipment and a transport mechanism, the vehicle can be transported from the transfer area to the lifting area while the vehicle angle can be corrected; in addition, the present invention can realize the storage and retrieval of multiple different vehicles at different positions in the parking area at the same time, saving the storage and retrieval time and improving the storage and retrieval efficiency.

[0078] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0079] like Figure 1 , 2 As shown in Figure 10, the present invention is a three-dimensional parking garage, comprising: a parking area 4, which is suitable for parking vehicles; a lifting area 5, on which a transport mechanism 3 is arranged, and the transport mechanism 3 is suitable for driving the vehicle to do lifting and lowering movements along the height direction of the parking area 4; a transfer area 6, which is suitable for parking vehicles to be stored and retrieved; a vehicle cleaning device 1, which is arranged in the transport mechanism 3 and is suitable for cleaning the vehicle; a differentiated access device 2, which is arranged in the transport mechanism 3, which is suitable for transporting the vehicle in the transfer area 6 to the lifting area 5 while correcting the parking angle of the vehicle, and then cooperating with the transport mechanism 3 to transport the vehicle to the parking area 4 for parking; or suitable for transporting the vehicle in the parking area 4 to the lifting area 5, and then cooperating with the transport mechanism 3 to transport the vehicle to the transfer area 6 for retrieval;

[0080] In this solution, the berth area can adopt a multi-story parking platform; the lifting area adopts a handling mechanism to lift the vehicle; the transfer area is used to park the vehicles to be stored and retrieved; usually one or both sides of the bottom of the multi-story parking platform are used as the transfer area.

[0081] The vehicle cleaning equipment can clean the vehicle while it is being transported, thus saving time; the differentiated storage and access equipment can correct the angle of vehicles parked in the transfer area, as well as realize forward or backward storage and access for multiple vehicles on the same parking platform.

[0082] like Figure 3 , 4 , 8, and 9, in order to illustrate the specific structure of the vehicle washing device, the vehicle washing device used in the present invention includes a lifting frame, which is suitable for lifting and lowering along the height direction of the vehicle; it includes a lifting component 100 located on the left and right sides of the vehicle, and a translation component 102 located on the front and rear sides of the vehicle;

[0083] The lifting frame is composed of a lifting component and a translation component. In this solution, two lifting components and two translation components are provided;

[0084] The translation component 102 is suitable for moving closer to or farther from the front and rear sides of the vehicle; that is, within the lifting frame, the translation component can move along the length direction of the vehicle.

[0085] A cleaning brush set 101 is disposed in the lifting component 100 or the translation component 102 and is adapted to synchronously approach or move away from the midpoint of the lifting component 100 or the translation component 102; a brush 103 is disposed on the cleaning brush set 101;

[0086] When the vehicle is stored in the handling area, the brush 103 on the cleaning brush set 101 is driven to fit the vehicle surface according to the vehicle wheelbase, and the lifting frame drives the brush 103 to descend or ascend;

[0087] The lifting component and the translation component serve as supports, and multiple cleaning brush groups are arranged therein. The cleaning brush groups can make translational movements toward the midpoints of the lifting component and the translation component inside the lifting component and the translation component. That is to say, the cleaning brush groups on both sides can gather toward the midpoints of the lifting component and the translation component, so that the total length of the multiple cleaning brush groups can be adjusted, the lengths of the multiple cleaning brush groups can be matched with the length and width of the vehicle, the brushes can be fitted to the surface of the vehicle, and the lifting frame can drive the brushes to descend or ascend to achieve vehicle cleaning.

[0088] It should be noted here that when the vehicle is put into storage, the lifting frame is located at the top to prevent it from interfering with the storage of the vehicle.

[0089] like Figure 4As shown, how to realize the lifting movement of the lifting frame, the present invention adopts a lifting frame connected with a vertically arranged screw 105 through a screw nut 104; a motor 106, which drives multiple screws 105 to rotate synchronously through the connection with the steering gear through a synchronous shaft 107.

[0090] The lifting and lowering movement of the lifting frame is achieved by the rotation of the lead screw driven by the motor, thereby realizing the lifting and lowering of the lead screw nut on the lead screw, and then realizing the lifting and lowering of the lifting frame on the lead screw; during the lifting process, only one motor is used, and the synchronous rotation of multiple lead screws is achieved through the cooperation of the synchronous shaft and the steering gear, so that the lifting frame is always in a horizontal state during the lifting process.

[0091] like Figure 4 As shown, in order to prevent the lifting frame from deflecting during movement, the present invention adopts a guide rod 108 fixedly arranged parallel to the screw rod 105, and the guide rod 108 passes through the lifting component 100;

[0092] The guide rod is parallel to the lead screw, and limits the lifting frame to only perform lifting movement during its movement.

[0093] like Figure 3 , 4 , 6, and 7, in order to illustrate the specific structure of the cleaning brush set 101, the present invention adopts a cleaning brush set 101 comprising: a first structure 110 and / or a second structure 111; wherein the second structure 111 is located on both sides of the plurality of first structures 110;

[0094] In the present embodiment, the cleaning brush group adopts the first structure or the second structure alone, or in combination. If the first structure is used alone, the structure is not compact enough; if the second structure is used alone, the number of components increases, which increases the cost. Therefore, it is preferred to adopt a combination of the first structure and the second structure, and the first structure is symmetrically arranged on both sides of the multiple second structures.

[0095] The first structure 110 includes a first connecting rod 112, one end of which is connected to the left and right screw rods 109, and the other end is connected to the brush 103; a second connecting rod 113, which is symmetrically arranged relative to the first connecting rod 112, one end of the second connecting rod 113 is hinged to the first connecting rod 112, and the other end is connected to the brush 103; a hydraulic cylinder 114, whose cylinder body is fixedly connected to the first connecting rod 112, and its piston rod is arranged upward or downward; a third connecting rod 115, which is symmetrically arranged, one end of which is hinged to the piston rod of the hydraulic cylinder 114, and the other end is hinged to the corresponding second connecting rod 113;

[0096] The second structure 111 includes a first connecting rod 112, one end of which is connected to the left and right screw rods 109, and the other end is connected to the brush 103; a second connecting rod 113, one end of which is hinged to one side of the first connecting rod 112, and the other end is connected to the brush 103; a hydraulic cylinder 114, the cylinder body of which is fixedly connected to the first connecting rod 112, and the piston rod of which is set upward or downward; a third connecting rod 115, one end of which is hinged to the piston rod of the hydraulic cylinder 114, and the other end is hinged to the second connecting rod 113;

[0097] A left and right screw rod 109 is arranged parallel to the length direction of the lifting component 100 or the translation component 102;

[0098] Two left and right screw rods 109 are provided, which can be located at the top or bottom of the lifting component 100 or the translation component 102;

[0099] When the left and right screw rods 109 rotate, the first connecting rod 112 is driven to move toward the midpoint of the lifting component 100 or the translation component 102, driving the brush 103 to be squeezed, and reducing the angle formed by the second connecting rod 113 and the piston rod of the hydraulic cylinder 114, extending the piston rod of the hydraulic cylinder 114; when the left and right screw rods 109 are reversed, the first connecting rod 112 is driven to move away from the midpoint of the lifting component 100, the piston rod of the hydraulic cylinder 114 is reset, and the angle formed by the second connecting rod 113 and the piston rod of the hydraulic cylinder 114 is enlarged, so that the brush 103 is restored to its original state.

[0100] That is to say, when the overall length of the cleaning brush group needs to be shortened, the left and right screws rotate to drive the brush to be squeezed, and the brush located at the end of the second connecting rod moves downward in line with the contour of the brush on the first connecting rod, thereby matching the overall length of the cleaning brush group with the vehicle length; in this process, the number of brushes in a certain area is squeezed and increased, thereby improving the cleaning efficiency.

[0101] The hydraulic cylinder plays a resetting role, and the piston rod of the hydraulic cylinder is in an extended state when the overall length of the cleaning brush group is shortened; when the overall length of the cleaning brush group is restored to the original length, the piston rod of the hydraulic cylinder retracts, thereby placing the multiple brushes on the cleaning brush group in a horizontal state.

[0102] like Figure 3 As shown, how to realize the rotation of the two left and right screw rods, the present invention adopts the left and right screw rods 109 ends connected to the second motor 116 through the second synchronization rod 117; the second motor 116 is suitable for driving the left and right screw rods 109 to rotate synchronously;

[0103] Only one second motor is provided, and the synchronization of the rotation of the two left and right screw rods is achieved through the connection of the second synchronization rod.

[0104] like Figure 7As shown, in order to illustrate the specific structure of the brush, the present invention adopts a brush 103 including a housing 118; an annular brush head 119, which is rotatably arranged in the housing 118; a third motor 120, which is fixed to the housing 118 and is suitable for driving the annular brush head 119 to rotate; a spray head 121, which sprays cleaning liquid obliquely from the center of the annular brush head 119 to the annular brush head 119;

[0105] The function of the shell is to prevent the annular brush head from being deformed during the extrusion process, thereby affecting its cleaning efficiency, and to collect water mist; the annular brush head is rotated by a third motor; in addition, the nozzle in this solution sprays the cleaning liquid onto the annular brush head instead of directly onto the outer surface of the vehicle. This has the advantage of reducing water splashing and saving water resources.

[0106] like Figure 7 As shown, in order to dry the vehicle after washing, the brush of the present invention also includes an air outlet device 122, in which the shell 118 is mounted, and the air outlet 123 of the air outlet device 122 is ring-shaped and faces the vehicle.

[0107] In this solution, the air outlet of the air outlet device faces the vehicle surface. During the vehicle cleaning process, air is blown onto the surface to accelerate the volatilization of moisture. The air outlet is annular, and when it fits against the vehicle surface, it forms an enclosed space to prevent water mist from splashing.

[0108] In summary, the vehicle cleaning equipment of the present multi-story parking garage adjusts the length of the cleaning brush group to adapt to the overall length of the vehicle, fits the brush to the surface of the vehicle, and cleans the entire vehicle through the lifting and lowering movement of the lifting frame; by adding the above-mentioned vehicle cleaning equipment to the multi-story parking garage, the vehicle can be cleaned during the process of vehicle transportation (driving the vehicle to lift, move, stop, etc.), so this design can reduce the footprint and improve efficiency.

[0109] like Fig.11 , 12As shown in the figure, in order to illustrate the specific structure of the differentiated access device, the differentiated access device adopted by the present invention includes at least one set of trailer frames 200, on which at least one pair of running wheels 201 are fixed; a traction mechanism 202, which is suitable for driving the trailer frame 200 to move forward or backward along its length direction; a tire gripping mechanism 203, which is set on the inner side or outer side of the trailer frame 200 and is suitable for clamping and lifting the corresponding tire of the vehicle; a posture control mechanism 204, which is suitable for controlling the synchronous deflection of the trailer frame 200 so that the length direction of the trailer frame 200 is parallel to the length direction of the vehicle; when the vehicle needs to be stored, the posture control mechanism 204 adjusts the trailer frame 200 The traction mechanism 202 drives the trailer frame 200 to move forward and places the trailer frame 200 on both sides of the bottom of the vehicle. The tire gripping mechanism 203 moves along the length direction of the trailer frame 200 according to the wheelbase of the vehicle to the side of the tire and then works to lift the vehicle. The vehicle is placed in the parking space and the angle of the trailer frame 200 is corrected at the same time. When the vehicle needs to be picked up, the traction mechanism 202 drives the trailer frame 100 to move forward or / and backward synchronously. After the vehicle placed in the parking space is clamped and lifted by the tire gripping mechanism 203, the traction mechanism 203 drives the vehicle to be placed in the transfer area.

[0110] In this scheme, when the vehicle is parked at an angle, before the trailer frame moves, the posture control mechanism adjusts the offset angle of the trailer frame to align it with the length direction of the vehicle, and then the trailer frame moves; the trailer frame is driven by the traction mechanism and the running wheels realize forward or backward movement of the trailer frame; the trailer frame moves forward or backward to pick up the vehicle, and moves backward or forward to store the vehicle; when the trailer frame moves to both sides of the bottom of the vehicle, the tire gripping mechanism works to lift the tires, thereby lifting the entire vehicle;

[0111] In addition, the device can be provided with multiple sets of traction mechanisms, trailer frames, and posture control mechanisms, so as to realize the storage and retrieval of multiple vehicles in different directions; when multiple vehicles stop in the transfer area, the device can drive the vehicles to move forward or backward after angle correction and store the corresponding vehicles in the corresponding parking spaces. The principle of the vehicle retrieval method is consistent with that of the vehicle storage method. Since the vehicles parked in the parking spaces are already in an angle correction state, the posture control mechanism does not need to be used in the vehicle retrieval process;

[0112] This device can achieve 1. The angles of vehicles with different wheelbases can be corrected simultaneously during the parking process; 2. When at least one set of this device is used, forward or backward parking and retrieval operations can be realized simultaneously; 3. When two or more sets of this device are used, multiple vehicles can be stored and retrieved simultaneously, thereby realizing the differentiated parking and retrieval of vehicles by this device.

[0113] like Fig.14As shown in the figure, in order to illustrate the specific structure of the traction mechanism, the traction mechanism 202 of the present invention includes a first sliding mechanism 205 and a second sliding mechanism 206 arranged up and down; a partition 207 is arranged between the first sliding mechanism 205 and the second sliding mechanism 206, and a bottom plate 208 is arranged at the bottom of the second sliding mechanism 206; the first sliding mechanism 205 includes: a first rack 209, which is parallel to the length direction of the trailer frame 200 and fixed to the bottom of the trailer frame 200; a first slide rail 210, which is parallel to the first rack 209 and fixed to the partition 207 The upper end surface; the first slider 211, which is arranged at the bottom of the trailer frame 200 and cooperates with the first slide rail 210; the first gear 212, which is arranged at the front side of the trailer frame 200 and cooperates with the first rack 209 to drive the trailer frame 200 to move forward; the second sliding mechanism 206 includes: a second rack 213, which is parallel to the length direction of the trailer frame 200 and fixed on the lower end surface of the partition 207; the second slide rail 214, which is parallel to the second rack 213, and is fixed on the upper end surface of the bottom plate 208; the second slider 215, which is arranged at the bottom of the partition 207 and cooperates with the second slide rail 214; the second gear 216, which is arranged at the rear side of the trailer frame 200 and cooperates with the second rack 213 to drive the trailer frame 200 together with the partition 207 to move backward.

[0114] In addition, in the traction mechanism, the first slider, the slide rail, the second slider, and the slide rail can be replaced in upper and lower positions.

[0115] The first sliding mechanism and the second sliding machine structure are arranged up and down, the first sliding mechanism drives the trailer frame to move forward, and the second sliding machine structure drives the trailer frame to move backward, that is, the travel of the device is 3 times the length of the trailer frame;

[0116] The first sliding mechanism and the second sliding mechanism are both realized by gears and racks, and the slide block and the slide rail play a guiding and supporting role.

[0117] like Fig.13 As shown, in order to illustrate the specific structure of the tire grabbing mechanism 203, the tire grabbing mechanism 203 adopted by the present invention includes: two lifting rods 217, one end of which is hinged to the accommodating cavity on the inner side or the outer side of the trailer frame 200, and the other end is provided with a wheel 218; two first connecting rods 219, one end of which is hinged to the corresponding lifting rod 217; a second connecting rod 220, one end of which is hinged to the other end of the first connecting rod 219; a hydraulic cylinder 221, the piston rod of which is fixedly connected to the midpoint of the second connecting rod 220; when the piston rod of the hydraulic cylinder 221 is extended, it is driven by the first and second connecting rods 220 and 219 to reduce the angle between the two lifting rods 217, so that the tire is placed on the lifting rod 217 and the vehicle is lifted;

[0118] The lifting rod is normally stored in the accommodating cavity. When work is required, the hydraulic cylinder drives the angle between the two lifting rods to decrease. Since the surface of the lifting rod is arc-shaped, it is tangent to the surface of the tire, so that the tire can be lifted;

[0119] In this solution, the wheels play the role of movement and support, and universal wheels are preferred.

[0120] like Fig.11 As shown, facing vehicles of different lengths, the position of the tires will change. How to realize that the tire-grabbing mechanism 203 can adapt to vehicles of different lengths? The present invention adopts a tire-grabbing mechanism 203 placed in a receiving cavity on the inner side or outer side of the trailer frame 200; a third slide rail parallel to the length direction of the trailer frame 200 is provided in the receiving cavity; a third slider matched with the third slide rail is provided on the tire-grabbing mechanism; a screw rod 222 is rotatably provided in the receiving cavity, and the screw rod 222 passes through the third slider; when the screw rod 222 rotates, the tire-grabbing mechanism 203 moves in the receiving cavity along the direction of the third slide rail;

[0121] That is to say, the tire-grabbing mechanism realizes movement relative to the length direction of the trailer frame through the rotation of the screw rod, thereby moving the tire-grabbing mechanism to one side of the tire; the cooperation of the slider and the slide rail also plays a supporting and guiding role.

[0122] like Fig.11 As shown, in order to illustrate the specific structure of the posture control mechanism, the posture control mechanism 204 adopted by the present invention includes: a rod body 223, which is rotatably connected to the middle part of the trailer frame 200; a fourth rack 224, both ends of which are respectively hinged to the ends of the trailer frame 200; a fourth gear 225; which is meshed with the fourth rack 224; when the fourth gear 225 rotates, the fourth rack 224 performs translational motion, driving the trailer frame 200 to rotate around the rod body 223;

[0123] Since the trailer frames can only move along their length direction, when the trailer frame rotates, the trailer frame can also rotate synchronously;

[0124] The rod body is hinged to the trailer frame, so the trailer frame can rotate around the rod body. The fourth gear, as a power source, meshes with the fourth rack, driving the fourth rack to move perpendicular to the length direction of the trailer frame. When the fourth rack is working, the angle between the fourth rack and the trailer frame bracket is not a right angle. At this time, the trailer frame rotates around the rod body so that it is parallel to the length direction of the vehicle.

[0125] like Fig.15As shown, in order to specifically illustrate how the fourth gear rotates, the present invention adopts a fourth gear 225 that is also meshed with a fifth rack 226. The fifth rack 226 is parallel to the fourth rack 224. A fourth motor 227 is provided on one side of the fifth rack 226. The fourth motor 227 drives the fifth rack 226 to perform translational motion, wherein the movement directions of the fourth and fifth racks 224 and 226 are opposite.

[0126] like Fig.12 As shown, the front and rear ends of the trailer frame 200 are hinged with a flip piece 228; when the vehicle needs to be stored or retrieved, the flip piece 228 is in a vertical state; when the vehicle stops on the trailer frame 200, the flip piece 228 is in a horizontal state, and the two ends of the flip piece at the front or rear end are interlocked to form a stable frame structure with the trailer frame 200.

[0127] In summary, the differentiated storage and retrieval equipment of the present multi-story parking garage realizes the forward and backward movement of the trailer frame through the traction mechanism, thereby realizing the storage and retrieval of the vehicle, lifts the vehicle through the tire gripping device, and corrects the offset angle of the vehicle when entering the garage through the posture control mechanism; in addition, the present equipment can realize the storage and retrieval of multiple different vehicles at different positions at the same time, saving the time for storage and retrieval and improving the efficiency of storage and retrieval.

[0129] The parking plate is provided with the above-mentioned vehicle cleaning equipment and differentiated access equipment; the parking plate realizes lifting and lowering movement relative to the garage frame through a power mechanism and a traction rope.

[0130] like Fig.16 As shown, in order to specifically explain the power mechanism, the power mechanism adopted by the present invention includes two lifting hydraulic cylinder groups which are in different planes and staggered; each lifting hydraulic cylinder group includes two lifting hydraulic cylinders 303, wherein the piston rods of the two lifting hydraulic cylinders 303 move in opposite directions; the traction rope 302 is wound around the piston rod of one lifting hydraulic cylinder, and the end thereof is fixed to the piston rod of the other lifting hydraulic cylinder 303;

[0131] There are four lifting hydraulic cylinders, two in a group, and the piston rods of every two lifting hydraulic cylinders can move in opposite directions. Four traction ropes are also set accordingly. The traction rope is wound around one of the piston rods and fixed to the other piston rod; in this way, the rising or falling distance of the parking plate can reach twice the elongation of the piston rod, ensuring the stroke of the parking plate.

[0132] Similarly, the telescopic movement of the piston rod of the lifting hydraulic cylinder can be replaced by the cooperation of the second screw rod and the second screw rod nut.

[0133] The present invention is a garage, which can realize cleaning of vehicles while they are moving in a lifting area through vehicle cleaning equipment, thus saving time; through the cooperation of differentiated storage and retrieval equipment and a transport mechanism, the vehicle can be transported from a transfer area to a lifting area while correcting the vehicle angle; in addition, the present invention can realize storage and retrieval of multiple different vehicles at different positions in a parking area at the same time, thus saving storage and retrieval time and improving storage and retrieval efficiency.

[0134] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
