Description

Technical Field

[0001] The present invention relates to the technical field of logistics handling equipment, and in particular to a lifting parking equipment and its AGV. Background Art

[0002] Nowadays, cars have become one of the main means of transportation for people to travel. When cars are in production, sale, and use, they often need to be carried. Therefore, handling equipment for carrying cars has emerged as the times require.

[0003] However, in order to meet the parking needs of a large number of cars and make the best use of the space area as much as possible, many designs of building multi-layer parking lots have emerged on the market. Most of the handling equipment on the market at present is single-layer handling, and usually cannot meet the requirement of raising a car by a certain distance to match the height of a multi-layer parking lot. Therefore, when the handling equipment transports the car to the parking position, it is also necessary to additionally raise the car to the specified height through a lifting device, and the operation is very troublesome.

[0086] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all belong to the scope protected by the present invention.

[0087] It should be noted that the terms "include" and "have" in the embodiments of the present invention and any of their deformations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0088] The embodiments of the present invention disclose a lifting parking device, which can realize automatic lifting of a vehicle, and the lifting parking device has a small occupied space, a simple structure and a low design difficulty.

[0089] Embodiment 1

[0090] Please refer to Figures 1 to 3 Figures 1 to 3 In Embodiment 1 of the present invention, a lifting parking device is disclosed, which includes a support frame 1 and two lifting devices 2. The support frame 1 is provided with a parking space 1a for parking vehicles. The two lifting devices 2 are respectively arranged on opposite sides of the support frame 1. Each lifting device 2 is provided with a clamping device 3 for supporting and clamping the vehicle. The lifting device 2 is used to drive the clamping device 3 to move up and down in the parking space 1a, so as to drive the vehicle to move up and down.

[0091] By forming the parking space 1a for parking vehicles within the support frame 1 and arranging the lifting device 2 within the parking space 1a, not only can the lifting of the vehicle be realized by means of the lifting device 2, but also the overall structure of the lifting parking device is made compact, the occupation of ground space can be reduced, and it can be applied to a compact garage.

[0092]

[0092] In this embodiment, the support frame 1 includes two first support rods 11, 12 that are parallel and spaced apart, and a third support rod 13 connected between the two first support rods 11, 12. The two first support rods and the third support rod 13 enclose to form the above-mentioned parking space 1a, and the two lifting devices 2 are respectively arranged on the two first support rods 11, 12. Specifically, the two first support rods 11, 12 can be horizontally arranged on the ground, and the distance between the two first support rods 11, 12 should be approximately equal to or slightly larger than the body width of the vehicle, so that the vehicle can be parked in the parking space 1a. The third support rod 13 is also horizontally arranged on the ground, and the third support rod 13 is connected to the two first support rods, so as to form a frame similar to a "door" shape with the two first support rods 11, 12. That is, the support frame 1 is generally in the shape of a door. Then the parking space 1a is the space formed inside the first support rod and the third support rod 13.

[0093] It can be known that since the two first support rods and the third support rod 13 form a frame similar to a door shape, therefore, the parking space 1a has a parking entrance and exit, which is located in the length direction of the first support rod, and when the vehicle enters and exits the parking space 1a, the length direction of the vehicle is the same as the length direction of the first support rod.

[0094] By adopting the method of forming a door-shaped frame with the first support rod and the third support rod 13, the distance between the two first support rods only needs to meet the requirement of being slightly larger than the body width of the vehicle. In this way, the lifting parking device of the present invention can minimize the occupation of ground space as much as possible, and at the same time, it can also be applied to a compact parking space, reducing the occupation of parking space.

[0095] Further, the first support rod can be a bar-shaped rod. The two ends of the first support rod in the length direction are respectively a first end 11a and a second end 11b. The first end 11a is connected to the third support rod 13, and a first pulley 111 is provided at the bottom of the second end 11b. Specifically, the first pulley 111 can be arranged at the end position close to the second end 11b. The first pulley 111 can be one or more, and the first pulley 111 can be a universal wheel. The first pulley 111 is used to move the lifting parking equipment, so as to carry the vehicle.

[0096] Furthermore, the third support rod 13 is also a bar-shaped rod. In order to increase the parking space 1a formed by the third support rod 13 and the two first support rods, the third support rod 13 is composed of three parts, namely a first rod part 13a, a second rod part 13b, and a third rod part (not shown). The first rod part 13a and the third rod part are respectively inclined and connected to the two first support rods 11 and 12. The second rod part 13b is connected between the first rod part 13a and the third rod part, and the second rod part 13b is a horizontal rod and is perpendicularly arranged with the two first support rods 11 and 12.

[0097] In this embodiment, a second pulley (not shown) is provided at the bottom of the third support rod 13. The connection lines between the first pulleys 111 provided on the two first support rods 11 and 12 and the second pulley provided on the third support rod 13 form a triangle. Specifically, the second pulley is arranged at a position close to the middle of the third support rod 13, so that the connection line from the second pulley to one of the first pulleys 111 is equal to the connection line from the second pulley to the other first pulley 111, and the formed triangle is an equilateral triangle. This can not only effectively move the lifting parking equipment, but also help the support frame 1 to maintain balance and stability. It can be known that the second pulley can also be one or more, and the second pulley can also be a universal wheel.

[0098] In this embodiment, as described above, the two lifting devices 2 are respectively arranged on the two first support rods 11 and 12. Therefore, a reinforcing block 112 can be provided at the position on the first support rod for arranging the lifting device 2. The reinforcing block 112 extends outward from the first support rod on the upper surface of the first support rod. The width of the reinforcing block 112 is greater than the width of the first support rod, so as to increase the contact area between the lifting device 2 and the reinforcing block 112 and ensure the fixation of the lifting device 2 on the reinforcing block 112.

[0099] Further, in order to further strengthen the strength of the two first support rods 11 and 12, a reinforcing rod 14 is also connected between the two first support rods 11 and 12. The reinforcing rod 14 is located in the parking space 1a and is perpendicularly connected to the two first support rods 11 and 12.

[0100] CombinedFigure 3 As shown, in this embodiment, the support frame 1 further includes a protective shell 15 enclosing the outer peripheries of the first support rod and the third support rod 13, and the protective shell 15 extends upward from the top surfaces of the first support rod and the third support rod 13, and the lifting device 2 is disposed within the protective shell 15. Specifically, the protective shell 15 may be a thin plate-like structure, including a first shell portion 15a, a second shell portion 15b, and a third shell portion 15c. The first shell portion 15a and the third shell portion 15c are respectively disposed on the two first support rods 11, 12, the third shell portion 15c is disposed on the third support rod 13, and the third shell portion 15c is connected to the first shell portion 15a and the second shell portion 15b. The extension height of the third shell portion 15c on the third support rod 13 is greater than the extension heights of the first shell portion 15a and the second shell portion 15b on the first support rod, and the first shell portion 15a and the second shell portion 15b are respectively connected to the two lifting devices 2. More specifically, the first shell portion 15a and the second shell portion 15b may be connected to the two lifting devices 2 by welding, so that the connection between the first shell portion 15a, the second shell portion 15b and the lifting device 2 is closer, and at the same time, the first shell portion 15a and the second shell portion 15b can be used to enhance the structural strength of the lifting device 2.

[0101] By arranging the protective shell 15 outside the lifting device 2, and using the protective shell 15, the two first support rods 11, 12 and the third support rod 13 to jointly enclose to form the parking space 1a. Thus, when a vehicle is placed in the parking space 1a, the protective shell 15 can effectively protect the vehicle placed in the parking space 1a and prevent scratches on the vehicle caused by surrounding objects during the moving and transporting process.

[0102] In this embodiment, in order to detect surrounding obstacles during the process of the lifting parking equipment transporting a vehicle and prevent collisions, a first obstacle sensor 113 is provided at the end of the second end 11b of the first support rod.

[0103] Furthermore, in order to enable the lifting parking equipment to move along a specified route during the process of transporting a vehicle and prevent collisions with obstacles in front of the route, the third shell portion 15c is provided with a laser sensor 151 and a second obstacle sensor (not labeled). The laser sensor 151 is disposed on the side of the third shell portion 15c facing away from the parking space 1a. That is, during the process of the lifting parking equipment moving forward, the third shell portion 15c can serve as the front end of the lifting parking equipment, and then the laser sensor 151 is arranged facing the forward direction of travel. Similarly, the second obstacle sensor can be disposed adjacent to the laser sensor 151, and the second obstacle sensor can be used to sense obstacles in front of the route to prevent collisions.

[0104] Furthermore, a cleaning brush 152 is provided at the bottom of the third housing part 15c. The cleaning brush 152 is used to brush off dust, obstacles, and other sundries on the traveling path of the lift parking equipment, thereby preventing sundries or dust from adhering to the bottom of the lift parking equipment.

[0105] Furthermore, in order to make the overall structure of the lift parking equipment more compact and facilitate the control of the lifting device 2 and the clamping device 3, an electric control box 153 is provided on the side of the third housing part 15c facing the parking space 1a. The electric control box 153 is used to control the power drive of the lifting device 2 and the power drive of the clamping device 3.

[0106] Embodiment 2

[0107] Please refer to Figure 2 、 Figure 4 and Figure 5 Based on the above Embodiment 1, the lift parking equipment of Embodiment 2 of the present invention further includes a connecting bracket 4, and the connecting bracket 4 is fixedly provided on the lifting device 2. As can be seen from Embodiment 1, there are two lifting devices 2, which are respectively arranged on the two first support rods 11 and 12. Two clamping devices 3 are provided on each lifting device 2 at intervals and arranged side by side. The connecting bracket 4 is connected between the two clamping devices 3 and is used to drive the two clamping devices 3 to perform lifting movement under the drive of the lifting device 2. That is, the function of the connecting bracket 4 is not only to connect the two spaced clamping devices 3, but also to drive the two clamping devices 3 to lift simultaneously under the drive of the lifting device 2, so as to realize the lifting of the vehicle.

[0108] Furthermore, the connecting bracket 4 includes a bearing member 4a and a fixing plate 4b extending upward from the bearing member 4a. The bearing member 4a is connected between the two clamping devices 3, and the fixing plate 4b is fixedly connected to the lifting device 2, so as to drive the bearing member 4a and the clamping device 3 to lift under the drive of the lifting device 2.

[0109] In this embodiment, the lift parking equipment further includes a telescopic mechanism 5. The telescopic mechanism 5 is arranged on the connecting bracket 4 and is fixedly connected to one of the clamping devices 3. The telescopic mechanism 5 is used to drive the one clamping device 3 to move linearly relative to the other clamping device 3 to adjust the distance between the two clamping devices 3. Specifically, the telescopic mechanism 5 can be a piston cylinder. The telescopic mechanism 5 is fixed on the bearing member 4a, and the piston rod of the telescopic mechanism 5 is connected to the one clamping device 3, so as to drive the one clamping device 3 to perform linear movement along the length direction of the bearing member 4a, thereby adjusting the distance between the two clamping devices 3. Furthermore, it can be adjusted according to the wheelbase of the front and rear wheels of the vehicle, so that the lift parking equipment can be applicable to vehicles with different wheelbases and improve the applicability of the lift parking equipment.

[0110] Furthermore, since the clamping device 3 can automatically clamp the tires of a vehicle, a driving device is provided inside the clamping device 3. The driving device needs to be connected to the electric control box 153 provided in the third housing part 15c through an electric wire. To prevent the electric wire from moving and getting messy when one of the clamping devices 3 moves linearly, the lift parking equipment further includes a first electric wire track 6a, a second electric wire track 6b, and a wire threading component 6c. The first electric wire track 6a is provided on the bearing component 4a, and the first electric wire track 6a is located between the two clamping devices 3. The second electric wire track 6b is provided parallel to the first electric wire track 6a on the fixing plate 4b and is located above the first electric wire track 6a. One end of the wire threading component 6c is slidably provided on the first electric wire track 6a and is connected to one of the clamping devices 3. The other end of the wire threading component 6c is fixedly provided on the second electric wire track 6b. The electric wire of one of the clamping devices 3 passes through the wire threading component 6c from the one clamping device 3. When the telescopic mechanism 5 drives the one clamping device 3 to move linearly relative to the other clamping device 3, one end of the wire threading component 6c can slide relative to the first electric wire track 6a.

[0111] Specifically, the first electric wire track 6a is a long strip-shaped track, and a groove is provided thereon. One end of the wire threading component 6c is slidably provided in the groove. Similarly, the second electric wire track 6b is also a long strip-shaped track, and the length extension direction of the second electric wire track 6b is the same as the length extension direction of the first electric wire track 6a. The other end of the wire threading component 6c is fixedly provided at the bottom of the second electric wire track 6b.

[0112] Furthermore, to enable one end of the wire threading component 6c to slide relative to the first electric wire track 6a under the pushing action of one of the clamping devices 3 when one of the clamping devices 3 moves linearly (for example, in the Figure 4 right direction as shown), and at the same time, it can also slide relative to the first electric wire track 6a under the pulling action of one of the clamping devices 3 when one of the clamping devices 3 moves to the right, a connecting part (not shown) protrudes from one of the clamping devices 3. The connecting part is arranged towards the groove of the first electric wire track 6a and is connected to one end of the wire threading component 6c.

[0113] In this embodiment, the threading component 6c is a flexible pipe or a tank chain, wherein the flexible pipe here generally refers to a pipe that can be deformed. Since the tank chain has low noise, high wear resistance and can move at high speed when in motion, the threading component 6c in this embodiment is preferably a tank chain. Specifically, the threading component 6c includes a first long strip portion 61, an arc portion 62 and a second long strip portion 63 connected in sequence, the first long strip portion 61 is arranged in the groove of the first wire track 6a, and the second long strip portion 63 is fixed to the second wire track 6b. The threading component 6c is preferably a tank chain, which is beneficial for the threading component 6c to play a role in traction and protection of the built-in wires when the threading component 6c reciprocates.

[0114] In addition, since the tank chain is composed of a large number of unit chains, that is, each section of the tank chain can be opened, the use of the tank chain as the threading component 6c is conducive to facilitating the installation of the wires in the tank chain and facilitating the maintenance of the wires.

[0115] Specifically, the process of the telescopic mechanism 5 driving one of the clamping devices 3 to move linearly is briefly described as follows (eg Figure 4 and Figure 5 4 shows the initial state of one of the clamping devices 3, Figure 5 It shows a state where one of the clamping devices 3 moves a certain displacement):

[0116] When the telescopic mechanism 5 is working, the telescopic mechanism 5 drives one of the clamping devices 3 to move to the left, and at the same time drives the first wire track 6a to move to the left. Since the first long strip portion 61 of the threading component 6c is slidably arranged on the first wire track 6a and connected to one of the clamping devices 3, and the second long strip portion 63 of the threading component 6c is fixedly arranged on the second wire track 6b, under the push of one of the clamping devices 3, the first long strip portion 61 of the threading component 6c can slide relative to the first wire track 6a, so as to drive the wires threaded through the threading component 6c to slide relative to the first wire track 6a, so that the positions of the wires and the threading component 6c can remain unchanged, thereby effectively avoiding the entanglement of the wires.

[0117] That is, in the second embodiment of the present invention, the telescopic mechanism 5 can not only effectively adjust the distance between the two clamping devices 3, so that the lifting parking equipment can be applicable to vehicles with different wheelbases. At the same time, the electric wire connected to one of the clamping devices 3 is connected to the electric control box 153 on the third housing part 15c after passing through the wire threading member 6c. Since the first wire track 6a is fixedly connected to one of the clamping devices 3, and one end of the wire threading member 6c is slidably disposed on the first wire track 6a and connected to one of the clamping devices 3, and the other end thereof is fixedly disposed on the second wire track 6b. Therefore, while the first wire track 6a moves reciprocally frequently following the telescopic mechanism 5 and one of the clamping devices 3, one end of the wire threading member 6c can slide relative to the first wire track 6a, so that the electric wire passing through the wire threading member 6c can remain relatively stationary with respect to the wire threading member 6c, thereby effectively avoiding the situation of wire entanglement during the reciprocating movement of one of the clamping devices 3, ensuring the normal operation of the lifting parking equipment, and improving the safety of the operation of the lifting parking equipment.

[0118] In addition, since the electric wire is first passed through the wire threading member 6c and then connected to one of the clamping devices 3, with such a structural design, the electric wire can be protected from being damaged by other external substances, further improving the service life of the electric wire.

[0119] Embodiment Three

[0120] Please refer to Figures 6 to 10 , on the basis of the above-mentioned Embodiment One and Embodiment Two, the lifting parking equipment of the third embodiment of the present invention, its lifting device 2 includes a first fixed gantry 2a, a first moving gantry 2b, a second moving gantry 2c, a sprocket assembly and a lifting mechanism 2e. The first moving gantry 2b is slidably disposed within the first fixed gantry 2a, the second moving gantry 2c is slidably disposed within the first moving gantry 2b, the sprocket assembly is located within the first moving gantry 2b, and the sprocket assembly includes a sprocket base 2d, a sprocket 2f and a chain 2g. The sprocket base 2d is fixedly disposed on the first moving gantry 2b, the sprocket 2f is fixed to the sprocket base 2d, the chain 2g is wound around the sprocket 2f and both ends of the chain 2g are respectively fixedly connected to the second moving gantry 2c and the first fixed gantry 2a. The lifting mechanism 2e is disposed on the first fixed gantry 2a, and the power output end of the lifting mechanism 2e is connected to the sprocket base 2d. The lifting mechanism 2e is used to drive the sprocket base 2d to perform a lifting movement, so that the sprocket base 2d drives the first moving gantry 2b to move up and down relative to the first fixed gantry 2a, and further enables the chain 2g to drive the second moving gantry 2c to move up and down relative to the first moving gantry 2b.

[0121] Specifically, as can be seen from the first embodiment above, when the lifting device 2 drives the clamping device 3 to lift the vehicle, the connection between the two clamping devices 3 is mainly achieved through the connection bracket 4. Therefore, the connection bracket 4 is connected to the second moving gantry 2c and moves up and down together with the second moving gantry 2c.

[0122] Combined with Figures 9 to 10 As shown, in this embodiment, the first fixed gantry 2a includes a bottom plate 21, the first moving gantry 2b includes a top plate 22, the lifting mechanism 2e is fixedly arranged on the bottom plate 21 of the first fixed gantry 2a, and the sprocket base 2d is fixedly arranged on the top plate 22 of the first moving gantry 2b. Preferably, in order to improve the stability of the second moving gantry 2c during the lifting movement, there are two sprockets 2f, which are respectively arranged on both sides of the sprocket base 2d, and chains 2g are wound around both sprockets 2f.

[0123] Specifically, the lifting mechanism 2e can be an electric cylinder. Since the power output end of the lifting mechanism 2e is fixedly connected to the sprocket base 2d, and the sprocket base 2d is fixedly connected to the top plate 22 of the first moving gantry 2b, when the lifting mechanism 2e works, the lifting mechanism 2e drives the sprocket base 2d to move up and down. At the same time, the sprocket base 2d drives the first moving gantry 2b to move up and down. And because the two ends of the chain 2g are respectively fixedly connected to the second moving gantry 2c and the bottom plate 21 of the first fixed gantry 2a, when the lifting mechanism 2e drives the sprocket base 2d to move, the chain 2g moves around the sprocket 2f to drive the second moving gantry 2c to move, so that the moving speed of the first moving gantry 2b is greater than the moving speed of the second moving gantry 2c, thereby making the lifting efficiency of the lifting mechanism 2e faster.

[0124] In this embodiment, in order to facilitate the lifting movement of the first moving gantry 2b to be more stable and smoother, the first fixed gantry 2a further includes two first vertical rods 21a vertically arranged on the bottom plate 21, the first moving gantry 2b further includes two second vertical rods 22a vertically arranged on the top plate 22. On both sides of the first vertical rod 21a, there are first sliding parts 211 respectively. On both sides of the second vertical rod 22a, corresponding to the two first sliding parts 211, there are second sliding parts 221, and the second sliding parts 221 are slidably connected to the first sliding parts 211. The first sliding part 211 is a slide rail or a slider, and the second sliding part 221 is a slider or a slide rail.

[0125] Preferably, the first sliding part 211 is a slide rail, the second sliding part 221 is a slider, and sliding grooves 221a are further provided on the outer sides of both sides of the second vertical rod 22a, and the second sliding part 221 is arranged in the sliding grooves 221a. Since the lifting mechanism 2e drives the first moving gantry 2b to move upward, and since the first sliding part 211 communicates with the outside world, the first moving gantry 2b may break free from the restraint of the first fixed gantry 2a. Therefore, in order to prevent the first moving door from detaching from the first fixed gantry 2a, limit members 211a are provided on the two first sliding parts 211, and the two limit members 211a are arranged away from the bottom plate 21 of the first fixed gantry 2a. The limit members 211a are slidably located in the sliding grooves 221a and are used to limit the upward sliding distance of the first moving gantry 2b relative to the first fixed gantry 2a, that is, the limit members 211a can limit the sliding distance of the first moving gantry 2b on the first fixed gantry 2a and prevent the first moving gantry 2b from detaching from the first fixed gantry 2a.

[0126] In order to make the lifting movement of the second moving gantry 2c more stable and smooth, third sliding parts 222 are respectively provided inside the two sides of the second vertical rod 22a, and fourth sliding parts 231 corresponding to the two third sliding parts 222 are respectively provided on the two sides of the second moving gantry 2c. The fourth sliding parts 231 are slidably connected to the third sliding parts 222. Among them, the third sliding part 222 is a groove or a protrusion, and the fourth sliding part 231 is a protrusion or a groove.

[0127] The process of the lifting device 2 moving upward is briefly described as follows:

[0128] As Figure 6 shown, Figure 6 shows the initial state of the lifting mechanism. At this time, both the first moving gantry 2b and the second moving gantry 2c are arranged close to the bottom plate 21 of the first fixed gantry 2a.

[0129] As Figure 7 shown, Figure 7 shows the limit state of the lifting of the lifting mechanism. At this time, both the first moving gantry 2b and the second moving gantry 2c have reached their highest rising positions.

[0130] When the lifting mechanism 2e works, the power output end of the lifting mechanism 2e lifts upward, pushing the sprocket base 2d to move upward, so as to drive the second sliding part 221 of the first moving gantry 2b to slide upward along the first sliding part 211 of the first fixed gantry 2a. At the same time, it drives the chain 2g to move around the sprocket 2f. Since one end of the chain 2g is connected to the second moving gantry 2c, by pulling with the chain 2g, it can drive the fourth sliding part 231 of the second moving gantry 2c to move upward along the third sliding part 222 of the first moving gantry 2b. Moreover, the first moving gantry 2b and the second moving gantry 2c reach their respective relative limit positions simultaneously. That is, the second moving gantry 2c moves upward under the combined drive of the sprocket base 2d and the chain 2g. Therefore, the upward movement speed of the second moving gantry 2c is twice the output speed of the power output end of the lifting mechanism 2e, and the lifting is more rapid.

[0131] At the same time, since the second moving gantry 2c moves driven by the chain 2g and is driven by the lifting mechanism 2e, the actual moving distance of the vehicle is the moving distance h1 of the first moving gantry 2b on the first fixed gantry 2a plus the moving distance h2 of the second moving gantry 2c relative to the first moving gantry 2b. In this way, without designing a higher moving gantry, the lifting device 2 can be applicable to parking racks of different heights, and the application range of the lifting device 2 is wider.

[0132] It can be known that since the lifting device 2 of the present invention is mainly used for lifting vehicles, in order to improve the bearing capacity of the first fixed gantry 2a of the lifting device 2, a second fixed gantry 2h is provided around the outer periphery of the first fixed gantry 2a, and the second fixed gantry 2h is fixed on the bottom plate 21 of the first fixed gantry 2a. In order to save costs, on the premise of not affecting the bearing capacity of the first fixed gantry 2a, the height of the second fixed gantry 2h can be selected to be lower than the height of the first fixed gantry 2a.

[0133] Specifically, in order to further strengthen the structural strength of the second fixed gantry 2h, the second fixed gantry 2h can be fixedly connected to the first support rod through a reinforcing rib plate.

[0134] Further, in order to further improve the bearing capacity of the first fixed gantry 2a of the lifting device 2 and make the lifting movement of the first moving gantry 2b more stable and smoother when the lifting mechanism 2e drives the first moving gantry 2b to move up and down, the lifting device 2 further includes a gantry reinforcement plate 25. Specifically, in order to realize the connection between the first vertical rod 21a and the gantry reinforcement plate 25, clamping portions (not labeled) are provided on the outer sides of both sides of the first vertical rod 21a, and buckle portions (not shown) are provided at both ends of the gantry reinforcement plate 25. The clamping portions are arranged near the top of the first vertical rod 21a, and the buckle portions are fixedly connected in cooperation with the clamping portions to prevent the first fixed gantry 2a from tipping over and ensure the safety of the operation of the lifting device 2. It can be understood that the clamping portions and the buckle portions can be the cooperation of a card slot and a protrusion.

[0135] In the lifting parking equipment provided by the embodiment of the present invention, a sprocket 2f assembly is provided at the power output end of the lifting mechanism 2e. The sprocket 2f fixing frame of the sprocket 2f assembly is connected to the first moving gantry 2b, and the chain 2g of the sprocket 2f assembly is connected to the second moving gantry 2c. By driving the movement of the sprocket 2f assembly through the lifting mechanism 2e, the movement of the first moving gantry 2b and the second moving gantry 2c is driven at the same time. With this structure, the sprocket 2f assembly uses the principle of a movable pulley to pull the lifting of the second moving gantry 2c, which can increase the lifting speed of the second moving gantry 2c, so that the speed of the second moving gantry 2c is greater than the speed of the first moving gantry 2b, so that the second moving gantry 2c can quickly rise to the specified height, thereby saving the lifting time of the lifting device 2.

[0136] Embodiment 4

[0137] Please refer to Figures 11 to 14 , on the basis of the above-mentioned Embodiment 1, Embodiment 2 and Embodiment 3, the lifting parking equipment provided by the fourth embodiment of the present invention has two lifting devices 2, which are the first lifting device 200 and the second lifting device 201 respectively. And as can be seen from the above-mentioned Embodiment 2, two clamping devices 3 are provided on each lifting device 2, and the two clamping devices 3 are the first clamping device 3a and the second clamping device 3b respectively. The first clamping device 3a provided on the first lifting device 200 is arranged opposite to the first clamping device 3a provided on the second lifting device 201, and the second clamping device 3b provided on the first lifting device 200 is arranged opposite to the second clamping device 3b provided on the second lifting device 201. And in order to improve the overall structural strength of the first clamping device 3a and the second clamping device 3b, therefore, the two first clamping devices 3a are connected together through a connecting rod member 7.

[0138] Specifically, as can be seen from the second embodiment above, the first clamping device 3a and the second clamping device 3b located on the same lifting device 2 are connected together by a connecting bracket 4. Therefore, when the first clamping device 3a and the second clamping device 3b clamp or release the vehicle's tire, their clamping or releasing is synchronized. For example, when the first clamping device 3a and the second clamping device 3b are positioned at the vehicle's tire, the first clamping device 3a and the second clamping device 3b can start clamping the vehicle's tire simultaneously. After the vehicle is parked, for example, parked in a parking space or lifted to a designated height and placed on a parking space or a parking rack, the first clamping device 3a and the second clamping device 3b can release the vehicle's tire simultaneously.

[0139] Further, as can be seen from the second embodiment above, the second clamping device located on the same lifting device can move linearly relative to the first clamping device to adjust the distance between the second clamping device and the first clamping device, so as to be applicable to the wheelbases of different types of vehicles.

[0140] In addition, when the lifting parking equipment clamps the vehicle, the two first clamping devices can be used to clamp the two front wheels or the two rear wheels of the vehicle. Correspondingly, the two second clamping devices can be used to clamp the two rear wheels or the two front wheels of the vehicle.

[0141] Since the structures of the two first clamping devices 3a are the same, the structure of one of the first clamping devices 3a will be described in detail in the present invention.

[0142] Combined with Figure 12 、 Figures 16 to 20As shown, in this embodiment, in order to make the structure of the first clamping device 3a compact and reduce the design difficulty, the first clamping device 3a includes a first fixed seat 31, a first fixed arm 32, a first rotating arm 33 and a first driving device. The first fixed arm 32 is fixedly arranged on the first fixed seat 31 and extends downward from the fixed seat. The first rotating arm 33 is rotatably arranged on the first fixed seat 31 and also extends downward from the first fixed seat 31. The first driving device is arranged on the first fixed seat 31, and the first driving device includes a first driving component 34a and a first transmission mechanism. The first transmission mechanism is connected to the first driving component 34a and the first rotating arm 33, and is used to drive the first rotating arm 33 to rotate to cooperate with the first fixed arm 32 to clamp the wheel of the vehicle or rotate to release the wheel of the vehicle under the drive of the first driving component 34a. Specifically, since the first clamping device 3a includes the first fixed arm 32 and the first rotating arm 33, the first fixed arm 32 of the first clamping device 3a located on the first lifting device 200 is connected to the first fixed arm 32 of the first clamping device 3a located on the second lifting device 201 through the connecting rod member 7. In this way, for the first fixed arms 32 of the two first clamping devices 3a, they cannot rotate. Thus, when positioning the tire of the vehicle, the tire of the vehicle can be quickly positioned to the connecting rod member 7, which not only plays a role in quick positioning, but also can enhance the structural strength of the first clamping device 3a. Preferably, the first fixed arm 32 is a long and round rod member, and the connecting rod member 7 is also a long and round rod member, so as to be able to fit the surface of the tire of the vehicle and avoid damaging the surface of the tire of the vehicle. In addition, the connecting rod member 7 can be integrally formed with the first fixed arm 32 or fixed to the first fixed arm 32 by means of welding or the like.

[0143] In this embodiment, the first driving component 34a can be a motor. The driving method is simple and reliable, and the design difficulty is low. By controlling the forward and reverse rotation of the motor, it can be realized that the driving transmission mechanism drives the first rotating arm 33 to rotate close to the first fixed arm 32 and cooperate with the first fixed arm 32 to clamp the wheel of the vehicle or rotate away from the first fixed arm 32 and release the wheel of the vehicle. The control method is simple and reliable. Compared with the way that the clamping assembly of the traditional vehicle handling equipment uses a two-way oil cylinder as the driving component and needs to design a hydraulic system, the clamping device 3 of the present invention uses a motor as the drive, without the need to set various hydraulic components and complex pipelines. The structure is simpler, the cost is lower, the design difficulty is lower, and there is no potential safety hazard of liquid medium leakage of the hydraulic system causing pollution.

[0144] Furthermore, in order to reduce the rotational speed transmitted from the first driving component 34a to the first transmission mechanism and increase the torque, the first driving device further includes a first speed reducer 34b. The first speed reducer 34b is connected to the first driving component 34a and the first transmission mechanism, thereby transmitting the higher rotational speed and lower torque output by the first driving component 34a to the first transmission mechanism, so that the first transmission mechanism obtains a smaller rotational speed and a larger torque, enabling the first transmission mechanism to drive the first rotating arm 33 to rotate with higher rotational accuracy and greater clamping force for clamping the vehicle wheel, and the clamping is reliable.

[0145] In this embodiment, the first rotating arm 33 includes a first rotating portion 33a and a first clamping portion 33b. The first rotating portion 33a is rotatably arranged on the first fixed seat 31 and extends downward from the first fixed seat 31 to be connected to the first clamping portion 33b, and the first clamping portion 33b is perpendicularly arranged to the first rotating portion 33a; the first fixed arm 32 includes a first fixed portion 32a and a second clamping portion 32b. The first fixed portion 32a is fixed on the first fixed seat 31 and extends downward from the first fixed seat 31 to be connected to the second clamping portion 32b, and the second clamping portion 32b is perpendicularly arranged to the first fixed portion 32a; wherein, a first included angle is formed between the first clamping portion 33b and the second clamping portion 32b. Specifically, as Figure 20 shown, the first rotating portion 33a includes a first part 331, a second part 332, and a third part 333 that are sequentially connected and arranged in a straight line. The first part 331 is a square rod, and the first part 331 is connected to the first transmission mechanism by means of nut pressing to enable the first rotating arm 33 to rotate driven by the first transmission mechanism. The second part 332 is a long cylindrical shape and is rotatably arranged on the first fixed seat 31 so that the first rotating arm 33 can rotate relative to the first fixed seat 31; the third part 333 is a rod approximately in an L shape with a square cross-section and is used to be connected to the first clamping portion 33b, thereby increasing the distance between the first clamping portion 33b and the first fixed seat 31 and preventing interference between the first clamping portion 33b and the first fixed seat 31 when the first clamping portion 33b rotates. The first fixed portion 32a includes a fourth part 321 and a fifth part 322 that are sequentially connected. The fourth part 321 is a long cylindrical shape, and the fourth part 321 is fixed on the first fixed seat 31 by means of nut pressing. The fifth part 322 is a long square shape, and the fifth part 322 is connected to the fourth part 321 and the second clamping portion 32b.

[0146] Further, both the first clamping portion 33b and the second clamping portion 32b are long cylindrical rods. When the first clamping portion 33b and the second clamping portion 32b clamp the wheel of a vehicle, the first clamping portion 33b and the second clamping portion 32b are tangent to the surface of the wheel, so as to avoid damaging the wheel when the first clamping portion 33b and the second clamping portion 32b clamp the wheel. By adopting the design of the first clamping portion 33b and the second clamping portion 32b being long cylindrical, that is, the cross-section of the first clamping portion 33b and the cross-section of the second clamping portion 32b are both circular, and the cross-section of the wheel is circular. When calculating the clamping force required to clamp the wheel of a vehicle, the weight of the vehicle can be exactly decomposed into two components, which are respectively from the tangent point of the cross-section of the first clamping portion 33b or the cross-section of the second clamping portion 2 and the cross-section of the wheel to the cross-section of the first clamping portion 33b or the cross-section of the second clamping portion 32b. Further decomposing the two components can obtain the required clamping force, and the calculation is simple, so that the design difficulty of the first clamping device 3a is relatively low.

[0147] Further, the first rotating arm 33 rotates close to or away from the first fixed arm 32 under the drive of the first driving component 34a, so as to adjust the size of the first angle between the first clamping portion 33b and the second clamping portion 32b, and thus the first clamping portion 33b and the second clamping portion 32b can clamp or release the wheel of the vehicle by adjusting the size of the first angle.

[0148] Specifically, in order to improve the adjustability of the angle between the first clamping portion 33b and the second clamping portion 32b, the range of the first angle between the first clamping portion 33b and the second clamping portion 32b is 0° to 90°. When the first angle is 0°, the first clamping portion 33b is arranged in parallel with the second clamping portion 32b; when the angle is 90°, the first clamping portion 33b is arranged perpendicular to the second clamping portion 32b. The adjustable range of the first angle between the first clamping portion 33b and the second clamping portion 32b is relatively large, so that the first clamping device 3a can clamp wheels of different sizes, that is, the lifting parking equipment of the present invention can be applicable to vehicles of different models.

[0149] In this embodiment, as Figure 11As shown, the first clamping device 3a further includes a first housing 35. The first fixing seat 31 and the first driving device are both arranged inside the first housing 35. The first rotating arm 33 and the first fixing arm 32 both partially extend outside the first housing 35. Specifically, the first housing 35 is approximately in the shape of a convex Chinese character. The first part 331 and the second part 332 of the first rotating arm 33 are located inside the first housing 35, and its third part 333 is located outside the first housing 35. The first clamping part 33b is located outside the first housing 35. The fourth part 321 of the first fixing part 32a is located inside the first housing 35, and its fifth part 322 is located outside the housing. The second clamping part 32b is located outside the housing. It can be understood that the first clamping device 3a only arranges the first clamping part 33b and the second clamping part 32b for clamping or loosening the vehicle, the third part 333 of the first rotating part 33a for preventing interference between the first clamping part 33b and the first housing 35 when the first clamping part 33b rotates, and the fifth part 322 of the first fixing part 32a outside the first housing 35, and other components are arranged inside the first housing 35, making the structure of the first clamping device 3a more compact and reducing the occupied space.

[0150] In this embodiment, the first transmission mechanism includes a first primary transmission mechanism connected to the first driving component 34a and a first secondary transmission mechanism connected to the first primary transmission mechanism and the first rotating arm 33. The first primary transmission mechanism is configured to perform a linear motion under the drive of the first driving component 34a and transmit it to the first secondary transmission mechanism, so that the first secondary transmission mechanism performs a curvilinear motion and drives the first rotating arm 33 to rotate.

[0151] Further, the first-stage transmission mechanism includes a first lead screw 340 vertically disposed on the first fixed seat 31 and connected to the first driving member 34a, a first lead screw nut 341 engaged with the first lead screw 340, and a first slider 342 connected to the first lead screw nut 341. The first slider 342 is used to perform the linear motion. To transmit the power output by the first driving member 34a to the first-stage transmission mechanism, the first driving device further includes a first gear set 343. The first gear set 343 is connected to the first reduction gear 34b and the first lead screw 340. Specifically, the first gear set 343 includes a first driving gear 343a disposed on the output shaft of the first reduction gear 34b, a first transmission gear 343b, and a first driven gear 343c disposed on the first lead screw 340. The first transmission gear 343b meshes with the first driving gear 343a and the first driven gear 343c. The gear transmission method is relatively simple and has a low design difficulty. More specifically, to support the first gear set 343, the first driving device further includes a first gear seat 343d and a first gear seat cover 343e. The first gear seat 343d is approximately square-shaped and is provided with a first support groove 343f. The first gear set 343 is disposed in the first support groove 343f. The first gear seat cover 343e is used to close the surface of the first gear seat 343d where the first support groove 343f is opened, so as to protect the first gear set 343 and prevent the first gear set 343 from being damaged due to exposure to the air, thereby extending the service life of the first gear set 343.

[0152] Further, the first-stage transmission mechanism further includes a first lead screw seat 340a and a first guide post 340b parallel to the first lead screw 340. The first lead screw seat 340a is fixedly disposed on the first fixed seat 31, the first lead screw 340 is connected to the first lead screw seat 340a, the first guide post 340b is fixedly disposed on the first fixed seat 31 and extends upward from the first fixed seat 31, and the first slider 342 is slidably disposed on the first guide post 340b. Since the first lead screw 340 is vertically disposed on the first fixed seat 31, the linear motion of the first lead screw nut 341 is a vertical motion along the first guide post 340b. That is, the first-stage transmission mechanism is a vertical transmission, and the stroke of the first lead screw 340 is short, so that the first lead screw 340 can adopt a single-sided lead screw seat support method, further simplifying the structure of the first-stage transmission mechanism and reducing the design difficulty. Specifically, the first lead screw seat 340a is connected to the first gear seat 343d and can be integrally formed.

[0153] Further, there are two first guide posts 340b. The two first guide posts 340b are spaced apart and arranged on the first fixed seat 31. The first fixed seat 31 is provided with two first guide holes 310 corresponding to the two first guide posts 340b, and the two first guide posts 340b are respectively fixed in the two first guide holes 310. Through this design, the first slider 342 slides more smoothly on the two first guide posts 340b, preventing the first lead screw 340 from jumping when rotating and causing damage to the first primary transmission mechanism, and extending the service life of the first primary transmission mechanism.

[0154] It can be known that the first primary transmission mechanism is a lead screw-nut transmission, with a simple and reliable transmission method and low design difficulty. At the same time, adopting this transmission method, the transmission accuracy is high. When the first rotating arm 33 and the first fixed arm 32 jointly clamp or loosen the vehicle wheel, it is more accurate, the clamping is more reliable, and over-tight clamping that may damage the vehicle wheel can be avoided.

[0155] In this embodiment, the first secondary transmission mechanism includes a first transmission rod 34c rotatably connected to the first slider 342 and a first rotating rod 34d rotatably connected to the first transmission rod 34c and connected to the first rotating arm 33. The first rotating rod 34d is used to perform the curvilinear motion and drive the first rotating arm 33 to rotate. Specifically, the curvilinear motion is a circular motion. In order to rotatably connect the first transmission rod 34c to the first slider 342, the first slider 342 is provided with a first connecting member 342a. The first connecting member 342a includes a first fixing rod 3420 fixed to the first slider 342 and a first connecting rod 3421 connected to the first transmission rod 34c. The first fixing rod 3420 is connected to the first connecting rod 3421 and is in a straight line. Through the first connecting member 342a, the first transmission rod 34c is rotatably connected to the first slider 342, which can prevent the first transmission rod 34c from interfering with the first slider 342 during movement, and further avoid the situation where the first transmission rod 34c collides with the first slider 342 and causes damage, thus extending the service life of the first transmission mechanism.

[0156] More specifically, in order to reduce the friction between the first rotating rod 34d and the first fixed seat 31 when the first rotating rod 34d rotates, a first friction pad 345 is provided between the first rotating rod 34d and the first fixed seat 31. Thus, when the first rotating rod 34d rotates, the first friction pad 345 can separate the first rotating rod 34d and the first fixed seat 31 to reduce the friction between the two, and extend the service life of the first clamping device 3a.

[0157] It can be known that the first and second transmission mechanisms are connecting rod mechanisms, the transmission method is simple and reliable, and the design difficulty is low. It only requires the first transmission rod 34c and the first rotating rod 34d to cooperate to convert linear motion into curved motion. Compared with the existing transmission method that requires additional design of a limiting structure, this transmission method has lower design difficulty.

[0158] In this embodiment, if Figure 20 As shown, the first fixed seat 31 is approximately convex-shaped, and the first fixed seat 31 includes a first surface 31a and a second surface 31b arranged opposite to each other. The first fixed seat 31 is provided with a first installation groove 311 penetrating the first surface 31a and the second surface 31b. The first reducer 34b is located in the first installation groove 311. The first driving component 34a is located above the first surface 31a of the first fixed seat 31 and in the space between the two first guide pillars 340b. The first driving component 34a and the first reducer 34b are arranged by grooving the first fixed seat 31 and making full use of the space between the two first guide pillars 340b, thereby reducing the space occupied by the first driving component 34a and the first reducer 34b, thereby making the overall structure of the first clamping device 3a more compact.

[0159] Furthermore, the first fixed seat 31 is provided with a second mounting groove 312 and a first screw hole 313. The second mounting groove 312 is provided on the second surface 31b of the first fixed seat 31 and is connected to the first mounting groove 311. The first screw 340 is provided in the first screw hole 313 and passes upward to the first surface 31a of the first fixed seat 31. The first screw seat 340a, the first gear seat 343d and the first gear seat cover 343e are provided in the second mounting groove 312. The first screw 340 extends upward from the first screw 340 to the outside of the first fixed seat 31. The first screw seat 340a, the first gear seat 343d, the first gear seat cover 343e and the first screw 340 are arranged by grooving and opening the first fixed seat 31, thereby reducing the space occupied by the first screw seat 340a, the first gear seat 343d, the first gear seat cover 343e and the first screw 340, thereby making the overall structure of the first clamping device 3a more compact.

[0160] In the embodiment of the present invention, Figure 21 As shown, the plane where the first slider 342 undergoes the linear motion is the first plane α, and Figure 21 The direction in which the first slider 342 moves up and down in the first plane α is shown. Figure 21 As shown by the up and down arrows on the first plane α, the plane where the first rotating rod 34d undergoes the curved motion is the second plane β, and Figure 21 The direction in which the first rotating rod 34d moves in the second plane β is shown. Figure 21As shown by the arrow direction on the second plane β, the second plane β is perpendicular to the first plane α. Specifically, the first plane α is a vertical plane, and the second plane β is a horizontal plane. The design that the linear motion and the curvilinear motion are in two mutually perpendicular planes enables the two motions to not interfere with each other, ensuring the normal transmission of the first transmission mechanism. At the same time, this design makes full use of two mutually perpendicular planes to achieve transmission, reducing the space occupied by the first transmission mechanism and making the overall structure of the first clamping device 3a more compact.

[0161] Furthermore, the plane in which the first transmission rod 34c moves is the third plane γ. The third plane γ is perpendicular to the second plane β, and the third plane γ and the first plane α are the same plane or different planes. Preferably, the third plane γ and the first plane α are the same plane. It can be understood that the first transmission rod 34c moves within the first plane α, and the first rotating rod 34d moves within the second plane β. That is, through the movement of the first transmission rod 34c and the first rotating rod 34d in two mutually perpendicular planes, the space occupied by the first secondary transmission mechanism is reduced, thereby making the overall structure of the gripper more compact.

[0162] It can be known that the first clamping device 3a makes full use of the space on the first fixed seat 31 to arrange the first driving component 34a, the first fixed arm 32, the first rotating arm 33, and the first transmission mechanism, etc., and realizes transmission by making full use of the movement plane, reducing the space occupied by each component. At the same time, it ensures that the movements of each component do not interfere with each other, making the overall structure of the first clamping device 3a more compact and occupying less space.

[0163] In this embodiment, the process of the first clamping device 3a clamping the wheel of a vehicle is as follows:

[0164] 1. The vehicle is in place: The vehicle stops with the wheel located between the first clamping part 33b and the second clamping part 32b, and the wheel abuts against the second clamping part 32b. At this time, the first fixed arm 32 can determine the position of the vehicle;

[0165] 2. Driving: The first driving component 34a rotates forward or backward, and the speed is reduced and the torque is increased through the first speed reducer 34b and transmitted to the first gear set 343;

[0166] 3. Gear transmission: The first driving gear 343a rotates and drives the first driven gear 343c to rotate through the first transmission gear 343b that meshes with the first driving gear 343a and the first driven gear 343c. The first driven gear 343c drives the first lead screw 340 to rotate forward or backward;

[0167] 4. Primary transmission: The rotation of the first lead screw 340 drives the first lead screw nut 341 that mates with the first lead screw 340 to move vertically downward along the first guide post 340b. The first lead screw nut 341 drives the first slider 342 to slide vertically downward along the first guide post 340b. The first slider 342 drives the first transmission rod 34c to move through the first connecting member 342a.

[0168] 5. Secondary transmission: The movement of the first transmission rod 34c drives the first rotating rod 34d to perform a circular motion, causing the first rotating arm 33 to rotate and approach the first fixed arm 32, thereby reducing the first angle between the first clamping portion 33b and the second clamping portion 32b, and achieving the clamping of the vehicle wheel by the first clamping portion 33b and the second clamping portion 32b.

[0169] And, the process of the first clamping device 3a releasing the vehicle wheel is as follows:

[0170] 1. Driving: The first driving component 34a rotates in reverse or forward, reduces the speed and increases the torque through the first speed reducer 34b, and transmits the power to the first gear set 343.

[0171] 2. Gear transmission: The first driving gear 343a rotates and drives the first driven gear 343c to rotate through the first transmission gear 343b that meshes with the first driving gear 343a and the first driven gear 343c. The first driven gear 343c drives the first lead screw 340 to rotate in reverse or forward.

[0172] 3. Primary transmission: The rotation of the first lead screw 340 drives the first lead screw nut 341 that mates with the first lead screw 340 to move vertically upward along the first guide post 340b. The first lead screw nut 341 drives the first slider 342 to slide vertically upward along the first guide post 340b. The first slider 342 drives the first transmission rod 34c to move through the first connecting member 342a.

[0173] 4. Secondary transmission: The movement of the first transmission rod 34c drives the first rotating rod 34d to perform a circular motion, causing the first rotating arm 33 to rotate and move away from the first fixed arm 32, thereby increasing the first angle between the first clamping portion 33b and the second clamping portion 32b, and achieving the release of the vehicle wheel by the first clamping portion 33b and the second clamping portion 32b.

[0174] Similarly, the structures of the two second clamping devices 3b are the same. Therefore, the structure of one of the second clamping devices 3b is described in detail in the present invention.

[0175] Combined with Figure 11 、 Figures 22 to 25As shown, the second clamping device 3b includes a second fixed seat 36, two second rotating arms 37, and a second driving device. The two second rotating arms 37 are rotatable and are arranged at intervals on the second fixed seat 36 and extend downward from the second fixed seat 36. The second driving device is arranged on the second fixed seat 36. The second driving device includes a second driving member 38 and a second transmission mechanism. The second transmission mechanism is connected to the second driving member 38 and the two second rotating arms 37, and is used to drive the two second rotating arms 37 to rotate to clamp or release the wheels of the vehicle. Specifically, the second rotating arm 37 includes a second rotating portion 37a and a third clamping portion 37b. The second rotating portion 37a is rotatably arranged on the second fixed seat 36 and extends downward from the second fixed seat 36 to be connected to the third clamping portion 37b, and the third clamping portion 37b is perpendicularly arranged with respect to the second rotating portion 37a. A second included angle is formed between the two third clamping portions 37b of the two second rotating arms 37.

[0176] Since the difference between the second clamping device 3b and the first clamping device 3a is that: the second clamping device 3b has two second rotating arms 37, and both of the two second rotating arms 37 can rotate under the drive of the second driving device. Therefore, the rotation angle between the two second rotating arms 37 is larger, that is, the adjustment range of the second included angle between the two third clamping portions 37b of the two second rotating arms 37 can be 0 to 180°. For example, as Figure 22 , 23 shown, when the second included angle is 0°, the two third clamping portions 37b are arranged in parallel; when the second included angle is 180°, as Figure 24 , 25 shown, the two third clamping portions 37b are arranged in a straight line. The adjustment range of the second included angle between the two third clamping portions 37b is relatively large, so that the second clamping device 3b can clamp wheels of different sizes, that is, it is realized that the lifting parking equipment can be applicable to vehicles of different models.

[0177] In addition, for the second clamping device 3b, its second driving device, that is, the structures of the second driving member 38 and the second transmission mechanism are the same as those of the first transmission mechanism and the first driving member 34a, and will not be elaborated here.

[0178] However, it should be noted that since both of the two second rotating arms 37 of the second clamping device 3b need to rotate, for the second transmission mechanism, its second first-level transmission mechanism has the same structure as the first first-level transmission mechanism. However, there are two second second-level transmission mechanisms, which are respectively connected to the two second rotating arms 37 to drive the two rotating arms to rotate.

[0179] In addition, for the specific structure of the second primary transmission mechanism, for example, the structures of the second fixed seat 36, the second lead screw, the second lead screw nut, the second slider, the second gear set, the second guide post, and the second lead screw seat included in the second primary transmission mechanism are the same as those of the first fixed seat 31, the first lead screw 340, the first lead screw nut 341, the first slider 342, the first gear set 343, the first guide post 340b, and the first lead screw seat 340a of the first primary transmission mechanism. Moreover, the connection relationship and the positional relationship between the second primary transmission mechanism and the second fixed seat are the same as those between the first primary transmission mechanism and the first fixed seat. Also, the transmission connection relationship between the second secondary transmission mechanism and the second primary transmission mechanism is the same as that between the first secondary transmission mechanism and the first primary transmission mechanism, which will not be elaborated here.

[0180] Similarly, for the specific structure of the second secondary transmission mechanism, for example, the specific structures of the second transmission rod and the second rotating rod are the same as those of the first transmission rod 34c and the first rotating rod 34d of the first secondary transmission mechanism, which will not be elaborated here.

[0181] Combined with Figure 21 As shown, for the second primary transmission mechanism and the second secondary transmission mechanism, the plane in which the second slider performs linear motion is also the fourth plane, and the plane in which the second rotating rod performs curvilinear motion can also be the fifth plane. The fourth plane is perpendicular to the fifth plane.

[0182] Similarly, the plane in which the second transmission rod moves is the sixth plane, the sixth plane is perpendicular to the fifth plane, and the sixth plane and the fourth plane are the same plane or different planes.

[0183] The ways in which the second slider performs linear motion, the second rotating rod performs curvilinear motion, and the second transmission rod moves are the same as the ways in which the first slider performs linear motion, the first rotating rod performs curvilinear motion, and the first transmission rod moves, respectively. Details will not be elaborated here and no illustrations will be provided.

[0184] In addition, the second clamping device 3b also includes a second housing. The above-mentioned second fixed seat 36 and the second driving device are both arranged inside the second housing, and the two second rotating arms 37 partially extend outside the second housing to facilitate clamping the tires of the vehicle.

[0185] The lifting parking equipment provided in the fourth embodiment of the present invention can accurately clamp each tire by correspondingly arranging four clamping devices 3 for the four tires of the vehicle, effectively ensuring the clamping reliability.

[0186] In addition, both the first clamping device 3a and the second clamping device 3b use a motor and a transmission mechanism to rotate the clamping arm to clamp or release the vehicle tire. This method has a simple structure, occupies a small space, has a low design difficulty, and can accurately position the vehicle.

[0187] In addition, by designing a primary transmission mechanism that performs linear motion and a secondary transmission mechanism that performs curvilinear motion under the drive of the primary transmission mechanism, and making the slider perform the linear motion in the first plane and the transmission rod perform the curvilinear motion in the second plane. At the same time, the first plane is perpendicular to the second plane, so as to make full use of the two mutually perpendicular planes to achieve transmission, reduce the space occupied by the transmission mechanism, and make the overall structure of the first clamping device 3a and the second clamping device 3b more compact.

[0188] In addition, the driving component uses a motor, the primary transmission mechanism uses a screw rod and a screw nut in cooperation, and the secondary transmission mechanism uses a transmission rod and a rotating rod in cooperation. The driving method and the transmission method are simple and reliable, and there is no need to design an additional limit structure, and the design difficulty is low.

[0189] The above has introduced in detail a lifting parking equipment disclosed in the embodiments of the present invention. This article uses specific examples to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand a lifting parking equipment of the present invention and its core idea; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation of the present invention.
