The clamping drive member 121 is connected to the frame 110, the output end of the clamping drive member 121 is connected to the screw rod 122, and the magnetic plate 123 is connected to the end of the screw rod 122 close to the clamping drive member 121; the transmission mechanism 130 includes a first connecting member 131, a second connecting member 132 and a magnetic plate 123. 2 and two connecting rods 133, the first connecting member 131 is adsorbed on the magnetic plate 123, the two ends of the first connecting member 131 are located on both sides of the screw rod 122, the second connecting member 132 is engaged with the screw rod 122, the second connecting member 132 is located on the side of the first connecting member 131 away from the magnetic plate 123, the two ends of the second connecting member 132 are located on both sides of the screw rod 122, and the two connecting rods 133 are respectively rotatably connected to the two ends of the second connecting member 132; the clamping arm mechanism 140 includes two clamping arm assemblies 141 and two The limiting rail 142, the two clamping arm assemblies 141 are symmetrically arranged on both sides of the screw rod 122, the clamping arm assembly 141 includes a clamping arm 1411 and a limiting member 1412, the limiting member 1412 is connected to the clamping arm 1411, the clamping arm 1411 is rotatably connected to one end of the first connecting member 131, and the end of the connecting rod 133 away from the second connecting member 132 is rotatably connected to the clamping arm 1411; the two limiting rails 142 are symmetrically arranged on both sides of the screw rod 122, and the limiting rails 142 are connected to the frame 110; wherein The second connecting member 132 can move along the screw rod 122 to drive the two clamping arms 1411 to open or close through the connecting rod 133, and the limiting member 1412 can enter the limiting track 142 as the clamping arms 1411 open or exit the limiting track 142 as the clamping arms 1411 close; there are two driving mechanisms 120, and the screw rods 122 of the two driving mechanisms 120 are coaxially arranged. There are two transmission mechanisms 130 and clamping arm mechanisms 140, and each clamping arm 1411 can move in the same plane.

[0033] Reference Figure 2The clamping action process is as follows: in one of the driving mechanisms 120, the clamping driving member 121 drives the screw rod 122 to rotate, driving the second connecting member 132 to move along the A1 direction. At this time, the first connecting member 131 is adsorbed on the magnetic plate 123 and does not move temporarily. The second connecting member 132 drives the connecting rod 133 to move. One of the connecting rods 133 drives a clamping arm assembly 141 to rotate around the B1 direction, and the other connecting rod 133 drives another clamping arm assembly 141 in the same clamping arm mechanism 140 to rotate around the B2 direction. The two clamping arm assemblies 141 open at the same time until one of them is The limiting piece 1412 of one clamping arm assembly 141 enters the limiting track 142 on one side, and the limiting piece 1412 of the other clamping arm assembly 141 enters the limiting track 142 on the other side. The limiting track 142 limits the limiting piece 1412, so that the clamping arm assembly 141 can no longer rotate and can only move horizontally. The clamping drive member 121 continues to drive the screw rod 122 to rotate, driving the second connecting member 132 to continue to move along the A1 direction. At this time, the clamping arm assembly 141 also moves along the A1 direction, driving the first connecting member 131 to move along the A1 direction until the two clamping arm assemblies 141 are clamped at On one side of the wheel; in another driving mechanism 120, the clamping driving member 121 drives the screw rod 122 to rotate, driving the second connecting member 132 to move along the A2 direction. At this time, the first connecting member 131 is adsorbed on the magnetic plate 123 and does not move temporarily. The second connecting member 132 drives the connecting rod 133 to move, and one of the connecting rods 133 drives a clamping arm assembly 141 to rotate around the B3 direction. The other connecting rod 133 drives another clamping arm assembly 141 in the same clamping arm mechanism 140 to rotate around the B4 direction. The two clamping arm assemblies 141 open at the same time until one of the clamping arm assemblies 14 1 enters the limiting track 142 on one side, and the limiting track 142 on the other clamping arm assembly 141 enters the limiting track 142 on the other side. The limiting track 142 limits the limiting member 1412, preventing the clamping arm assembly 141 from further rotation and only allowing translation. The clamping drive 121 continues to drive the screw rod 122 to rotate, driving the second connecting member 132 to continue moving in the A2 direction. At this time, the clamping arm assembly 141 also moves in the A2 direction, driving the first connecting member 131 to move in the A2 direction until the two clamping arm assemblies 141 clamp the other side of the wheel. In the same set of drive mechanism 120, transmission mechanism 130, and clamping arm mechanism 140, only one clamping drive 121 drives one screw rod 122 to rotate to drive the clamping arm 1411 to perform the clamping action of first opening and then translation. The drive mechanism 120 is relatively simple and has low manufacturing and use costs.

[0034] In some embodiments of the present invention, the clamping arm assembly 141 further includes a roller 1413 , which is rotatably connected to the outer side of the clamping arm 1411 .

[0035] For example, Figures 1 to 2As shown, the clamping arm assembly 141 further includes a roller 1413, which is rotatably connected to the outer side of the clamping arm 1411. After the clamping arm assembly 141 is opened and translated until it contacts the wheel, the roller 1413 directly contacts the wheel. The clamping arm assembly 141 continues to translate to lift the wheel. The roller 1413 and the wheel generate rolling friction, which can reduce the friction between the clamping arm assembly 141 and the wheel during the wheel lifting process, thereby reducing driving energy consumption.

[0036] In some embodiments of the present invention, the limiting member 1412 is rotatably connected to the clamping arm 1411 .

[0037] For example, Figure 1 As shown, the connection relationship between the limiter 1412 and the clamping arm 1411 is shown. Figure 1 The limiting member 1412 is rotatably connected to the clamping arm 1411. When the clamping arm assembly 141 rotates until the limiting member 1412 enters the limiting track 142, rolling friction occurs between the limiting member 1412 and the limiting track 142. This reduces the friction between the limiting member 1412 and the limiting track 142, making the movement of the clamping arm mechanism 140 smoother and reducing driving energy consumption.

[0038] In some embodiments of the present invention, both ends of the first connecting member 131 are provided with receiving grooves 1311 , and the clamping arms 1411 are partially received in the receiving grooves 1311 .

[0039] For example, Figure 3 As shown, both ends of the first connecting member 131 are provided with a receiving groove 1311, referring to Figure 1 and Figure 2 The clamping arm 1411 is partially accommodated in the accommodating groove 1311 , and the groove wall of the accommodating groove 1311 can play a certain limiting role on the clamping arm 1411 , thereby improving the stability of the movement.

[0040] In some embodiments of the present invention, the second connecting member 132 includes a connecting portion 1321 and a transmission portion 1322, the transmission portion 1322 is connected to the connecting portion 1321, the two connecting rods 133 are respectively rotatably connected to the two ends of the connecting portion 1321, and the transmission portion 1322 is sleeved on the screw rod 122 and engaged with the screw rod 122.

[0041] For example, Figure 3 As shown, the second connecting member 132 includes a connecting portion 1321 and a transmission portion 1322. The transmission portion 1322 is connected to the connecting portion 1321. Two connecting rods 133 are rotatably connected to the two ends of the connecting portion 1321. The transmission portion 1322 is sleeved on the screw rod 122 and meshed with the screw rod 122. The transmission portion 1322 can extend the meshing length between the second connecting member 132 and the screw rod 122, thereby improving the stability of the movement of the second connecting member 132.

[0042] In some embodiments of the present invention, the first connecting member 131 defines a clearance hole 1312 , the screw rod 122 passes through the clearance hole 1312 , and the transmission portion 1322 is partially accommodated in the clearance hole 1312 and can move relative to the first connecting member 131 .

[0043] For example, Figure 3 As shown, the first connecting member 131 is provided with an avoidance hole 1312, the screw rod 122 is passed through the avoidance hole 1312, the transmission part 1322 is partially accommodated in the avoidance hole 1312 and can move relative to the first connecting member 131. The structural layout is relatively compact and can save installation space.

[0044] An embodiment of the second aspect of the present invention provides a car transporter for transporting cars, comprising: a wheel clamping device 100 provided in any embodiment of the first aspect of the present invention, two wheel clamping devices 100 are provided, one wheel clamping device 100 is used to clamp the two front wheels of the car, and the other wheel clamping device 100 is used to clamp the two rear wheels of the car; a guide rail 200, the wheel clamping device 100 is placed on the guide rail 200 and can move along the guide rail 200.

[0045] For example, Figure 4 As shown, the vehicle transporter includes a wheel clamping device 100 and a guide rail 200. Two wheel clamping devices 100 are provided, one for clamping the vehicle's two front wheels, and the other for clamping the vehicle's two rear wheels. The wheel clamping devices 100 are placed on the guide rail 200 and can move along the guide rail 200 to accommodate vehicles with different wheelbases. The wheel clamping device 100, which utilizes a single screw rod 122 to drive the clamping arm 1411 to first open and then translate, reduces the number of drive components and lowers manufacturing and operating costs.

[0046] In some embodiments of the present invention, the car transporter further includes a driving device 300, which includes a translation driving member 310 and a driving wheel 320. The translation driving member 310 is connected to the frame 110, and the driving wheel 150 is connected to the output end of the translation driving member 310. The driving wheel 320 contacts the guide rail 200. The translation driving member 310 is used to drive the driving wheel 320 to rotate to drive the wheel clamping device 100 to move along the guide rail 200.

[0047] For example, Figure 4As shown, the car transporter further includes a driving device 300, which includes a translation driving member 310 and a driving wheel 320. The translation driving member 310 is connected to the frame 110, and the driving wheel 150 is connected to the output end of the translation driving member 310. The driving wheel 320 contacts the guide rail 200. The translation driving member 310 is used to drive the driving wheel 320 to rotate, thereby driving the wheel clamping device 100 to move along the guide rail 200. The translation driving member 310 can output a stable driving force, thereby improving the translation stability of the wheel clamping device 100.

[0048] In some embodiments of the present invention, the wheel clamping device 100 further includes a driven wheel 150 , which is rotatably connected to the frame 110 and contacts the guide rail 200 .

[0049] For example, Figures 1 to 4 As shown, the wheel clamping device 100 further includes a driven wheel 150, which is rotatably connected to the frame 110 and contacts the guide rail 200. During translation of the wheel clamping device 100, the driven wheel 150 contacts the guide rail 200 and generates rolling friction, which can reduce the friction between the wheel clamping device 100 and the guide rail 200 and lower the driving energy consumption.

[0050] It is understandable that the driven wheel 150 can be arranged vertically or horizontally. The driven wheel 150 arranged vertically can provide support in the vertical direction, and the driven wheel 150 arranged horizontally can limit the frame 110 in the horizontal direction.

[0051] A third embodiment of the present invention provides a three-dimensional parking garage, comprising the car transporter provided by any embodiment of the second embodiment of the present invention.

[0052] The use of a car transporter that can reduce the number of driving components and reduce manufacturing and use costs can reduce the overall manufacturing and use costs of a three-dimensional parking garage.
