Description

TECHNICAL FIELD

[0001] The utility model belongs to the related technical field of vehicle handling, especially relates to a vehicle handler and stereo garage. BACKGROUND

[0002] The vehicle handler is applied to the stereo garage and is used for handling vehicles to realize the purpose of taking and storing vehicles in the stereo garage.

[0003] The mechanical hand of the vehicle handler is usually integrally provided with a walking wheel mechanism and a clamping arm mechanism. When the mechanical hand works, the walking wheels of the walking wheel mechanism drive the mechanical hand to walk on the walking surface, and the four sets of mechanical hand clamping arms in the clamping arm mechanism clamp or release the front and rear wheels of the vehicle to realize the movement of the vehicle. At present, the clamping arm mechanism of the existing mechanical hand usually adopts a form of a whole drive of one motor or independent drive of four clamping arms by four motors to realize the control switching of the clamping arm state. When the four sets of clamping arms of the mechanical hand are driven by one motor, the demand for motor power is large, which leads to a large size of the motor. In addition, the transmission assembly for the transmission connection between the one motor and the four mechanical hand clamping arms and the walking wheel driving assembly in the walking wheel mechanism usually intersects, which increases the assembly space and is not conducive to the thinning improvement of the overall thickness of the mechanical hand. When the mechanical hand selects four motors to independently drive one set of mechanical hand clamping arms, the corresponding servo and other electrical accessories for controlling the four motors also increase, which not only increases the failure rate of the mechanical hand, but also is not conducive to the miniaturization improvement of the overall size of the mechanical hand. In addition, the four sets of clamping arms are driven by four motors respectively, and the motion synchronization between the clamping arms is poor in the use process, which is not conducive to the stable clamping action of the vehicle. SUMMARY

[0009] Two clamping arm driving assemblies are respectively in driving connection with the two pairs of clamping arm mechanisms to drive the mechanical hand clamping arms to rotate relative to the frame body.

[0010] In the width and height directions perpendicular to the running direction of the frame body, the walking wheel driving assembly is arranged between the two mechanical hand clamping arms of each pair of the clamping arm mechanisms.

[0011] It can be understood that the two clamping arm driving assemblies are used to control the rotation of the four mechanical hand clamping arms on the frame body, and the walking wheel driving assembly is arranged between the two mechanical hand clamping arms of each pair of the clamping arm mechanisms, so that the arrangement of the walking wheel mechanism and the clamping arm mechanism in the height direction of the frame body does not affect each other, so that the vehicle carrier can reduce the size of the carrying unit in the height direction and the length direction on the basis of reducing the number of electrical accessories matched with the clamping arm mechanism; and the vehicle carrier has good synchronization and few fault points when working.

[0014] In one embodiment, the mechanical hand clamping arm comprises a swing seat rotatably mounted on the frame body, wherein an arc-shaped tooth is formed on the swing seat.

[0015] The clamping arm driving assembly comprises a first rotary driving member, a synchronous transmission unit and two worms, the first rotary driving member is driving connected with the two worms through the synchronous transmission unit to link the two worms, and the two worms are respectively engaged with the arc-shaped teeth on the swing seats of the two mechanical hand clamping arms.

[0016] In one embodiment, the walking wheel driving assembly comprises a second rotary driving member, a driving shaft and two gear sets, the two gear sets are linked by the driving shaft and are respectively driving connected with the second rotary driving member.

[0017] The two gear sets are respectively driving connected with the two walking wheel sets.

[0019] In one of the embodiments, the mechanical arm clamping arm comprises a swing seat, which is rotatably installed on the frame body through a vertical rotating shaft;

[0020] It can be understood that, by using the structural characteristics of the tapered roller bearing and the plain bearing, the load-bearing capacity of the swing seat when installed on the frame body can be ensured, and the overall thickness of the swing seat when assembled on the frame body can be reduced.

[0021] In one of the embodiments, the mechanical arm clamping arm comprises a swing seat and an arm rod, the swing seat is rotatably installed on the frame body and connected with the arm rod, and the swing seat can drive the arm rod to rotate on the frame body to switch the arm rod between the folded state and the working state.

[0022] When the arm rod is in the folded state, the arm rod is arranged parallel to the long side of the frame body, and a preset gap is formed between the arm rod and the long side.

[0023] It can be understood that, by the above-mentioned assembly method of the mechanical arm clamping arm on the frame body, the size of the carrying unit in the width direction is shortened.

[0024] In one of the embodiments, the carrying unit further comprises a control module and a damping mechanism, the control module is installed on the frame body through the damping mechanism, and is electrically connected with the walking wheel mechanism and the clamping arm mechanism respectively.

[0025] In one of the embodiments, the carrying unit further comprises a control module and a damping mechanism, the control module is installed on the frame body through the damping mechanism, and is electrically connected with the walking wheel mechanism and the clamping arm mechanism respectively.

[0026] It can be understood that, by using the damping mechanism to damp and buffer the assembly of the control module on the frame body, the stability of the electrical connection between the control module and the walking wheel mechanism and the clamping arm mechanism can be improved, so that the stability and control accuracy of the carrying unit during operation can be ensured.

[0027] In one of the embodiments, the vehicle carrier further comprises a pull rod, the pull rod is arranged across the two frame bodies and is slidably connected with the two frame bodies respectively, and is used for guiding and supporting the two frame bodies.

[0028] It can be understood that the two frame bodies are guided and supported by the pull rod, so that the two manipulators can save the structure of the front and rear driven wheel sets and the side guide wheel sets, thereby reducing the cost.

[0030] When the two locking mechanisms lock the pull rod on the corresponding frame body, the distance between the two carrying units is locked.

[0031] It can be understood that the two locking mechanisms are used to mechanically lock the pull rod to lock the distance between the two carrying units, which can ensure the synchronization of the movement of the two carrying units and avoid the situation that the vehicle tires slip out of the manipulator clamping arms when the vehicle carrier carries the vehicle, thereby improving the carrying efficiency of the vehicle carrier and reducing the cost.

As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0052] AsFigure 1 、 Figure 2 As shown in FIGS. 1, 2 and 3, the vehicle carrier 100 provided by the present application is used for carrying vehicles, and comprises two carrying units 10 respectively used for carrying front and rear wheels of a vehicle, wherein each carrying unit 10 comprises a frame body 11, a traveling wheel mechanism 12, two pairs of clamping arm mechanisms 13 and two clamping arm driving assemblies 132; the traveling wheel mechanism 12 comprises a traveling wheel set 121 and a traveling wheel driving assembly 122, the traveling wheel driving assembly 122 is in driving connection with the traveling wheel set 121 and is used for providing power for the traveling of the traveling wheel set 121 to drive the frame body 11 to travel; each pair of clamping arm mechanisms 13 is located at two sides of the frame body 11, and each pair of clamping arm mechanisms 13 comprises two mechanical hand clamping arms 131 which are rotatable relative to the frame body 11, and the two mechanical hand clamping arms 131 located at the same side of the frame body 11 can be close to each other to clamp and hold a vehicle tire; the two clamping arm driving assemblies 132 are in driving connection with the two pairs of clamping arm mechanisms 13 respectively to drive the mechanical hand clamping arms 131 to rotate relative to the frame body 11; and in the width and height directions perpendicular to the running direction of the frame body 11, the traveling wheel driving assembly 122 is located between the two mechanical hand clamping arms 131 of each pair of clamping arm mechanisms 13. Here, the number of the traveling wheel set 121 is two, and the number of the traveling wheel 1211 in each traveling wheel set 121 is two. It can be understood that in other embodiments, the number of the traveling wheel 1211 in each traveling wheel set 121 can also be one, three or even more, which will not be described here.

[0053] As can be seen from the above, the carrying unit 10 of the present application uses two clamping arm driving assemblies 132 to control the rotation of the four mechanical hand clamping arms 131 on the frame body 11, and arranges the traveling wheel driving assembly 122 between the two mechanical hand clamping arms 131 of each pair of clamping arm mechanisms 13, so that the arrangement of the traveling wheel mechanism 12 and the clamping arm mechanism 13 in the height direction of the frame body 11 does not affect each other, so that the vehicle carrier 100 can reduce the size of the carrying unit 10 in the height direction and the length direction on the basis of reducing the number of electrical accessories matched with the clamping arm mechanism 13; and the vehicle carrier 100 has good synchronization and few fault points when working.

[0054] It should be noted that the carrying unit 10 of the present application has a small height space when the whole carrying unit 10 travels on the traveling surface, which is less than 95 mm, so that when the vehicle carrier 100 is applied to a stereo garage, the overall height of the carrying unit 10 is higher than the ground clearance of the vehicle chassis, so that the carrying unit 10 can directly enter the parking surface of the stereo garage from the traveling surface of the stereo garage for parking, and therefore the stereo garage can be arranged flush with the traveling surface and the parking surface, so that the manufacturing cost of the parking space of the stereo garage can be reduced, and the manufacturing difficulty and cost of the corresponding matched components can be reduced.

[0055] As Figure 1 ,Figure 2 As shown, in one embodiment, each walking wheel set 121 is positioned between two robotic gripper arms 131 in each set of robotic gripper arms 131, and a walking wheel drive assembly 122 is positioned between the two walking wheel sets 121. The two gripper arm drive assemblies 132 are positioned on both sides of the walking wheel drive assembly 122 along the length of the frame 11, and are respectively connected to the two robotic gripper arms 131 located on the same side of the walking wheel set 121. This allows the walking wheel drive assembly 122 and the two gripper arm drive assemblies 132 to be staggered on the frame 11, without affecting each other. Here, the two gripper arm drive assemblies 132 are concentrated on one side of the frame 11 along its width. It can be understood that in other embodiments, the two gripper arm drive assemblies 132 may also be positioned on both sides of the frame 11 along its width.

[0056] like Figure 3 As shown, in one embodiment, the robotic gripper arm 131 includes a swing seat 1311, which is rotatably mounted on the frame 11 via a vertical pivot 133. This allows each set of robotic grippers 131 for gripping car wheels to have a folded state against both sides of the frame 11 and a working state perpendicular to the sides of the frame 11. Here, when the robotic gripper arm 131 is in the folded state, the length of the handling unit 10 does not exceed 1900mm, the width does not exceed 1015mm, and the height does not exceed 95mm, allowing the handling unit 10 to move freely between the flush walking surface and the parking surface for parking vehicles in the automated parking garage.

[0057] like Figures 1 to 3 As shown, in this embodiment, the robotic gripper arm 131 further includes an arm 1312 connected to a swing base 1311, and the swing base 1311 can drive the arm 1312 to rotate on the frame 11, so that the arm can switch between a folded state and a working state. Here, when the arm 1312 is in the folded state, the arm 1312 is arranged parallel to the long side 111 of the frame 11, and a preset gap is formed between the arm 1312 and the long side 111, which can shorten the dimension of the handling unit 10 in the width direction.

[0058] like Figure 5As shown in the figure, in an embodiment, the clamping arm driving assembly 132 comprises a first rotary driving member 1321, a synchronous transmission unit 1322 and two worms 1323, the first rotary driving member 1321 is in transmission connection with the two worms 1323 through the synchronous transmission unit 1322, so that the two worms 1323 are linked together, and each worm 1323 is in meshing engagement with the arc-shaped tooth 13111 on the swing seat 1311, respectively, so that when the clamping arm driving assembly 132 works, one first rotary driving member 1321 can realize linkage between the corresponding two robot clamping arms 131 under the transmission of the synchronous transmission unit 1322 and the two worms 1323, so as to control the robot clamping arms 131 to switch back and forth between the folding state and the working state on the frame body 11. Here, the first rotary driving member 1321 is configured as a motor, a rotary cylinder, etc., and the synchronous transmission unit 1322 can be a chain wheel and chain, a synchronous belt, etc.

[0059] As shown in the figure, Figure 3 In an embodiment, the vertical rotating shaft 133 passes through the part of the robot clamping arm 131 downward and is in rotary connection with the frame body 11 through the tapered roller bearing 101, and the vertical rotating shaft 133 passes through the part of the robot clamping arm 131 upward and is in rotary connection with the frame body 11 through the plane bearing 102. In this way, the structural characteristics of the tapered roller bearing 101 and the plane bearing 102 can not only ensure the load-bearing capacity of the connecting part between the robot clamping arm 131 and the frame body 11, but also thin the overall thickness of the connecting part. Here, the plane bearing 102 is a bronze bearing. It can be understood that in other embodiments, the plane bearing 102 can also be a copper bearing, a rolling bearing, etc., which will not be expanded here. It should be noted that since the tapered roller bearing 101 has a large load-bearing capacity, it can meet the load-bearing capacity of the assembly between the vertical rotating shaft 133 and the frame body 11; and the height dimension of the plane bearing 102 is smaller than that of the tapered roller bearing 101, so as to thin the overall thickness of the connecting part.

[0060] As shown in the figure, Figure 4As shown in the figure, in an embodiment, the walking wheel driving assembly 122 comprises a second rotating driving member 1221, a driving shaft 1223, two gear sets 1224 which are linked by the driving shaft 1223 and are respectively in transmission connection with the second rotating driving member 1221, and two walking wheel sets 121 which are respectively in transmission connection with the two gear sets 1224. Thus, when the walking wheel driving assembly 122 works, one second rotating driving member 1221 can realize the motion control of the two walking wheel sets 121 under the transmission of the driving shaft 1223 and the gear sets 1224. Here, the second rotating driving member 1221 can be configured as an electric motor which is arranged side by side with the driving shaft 1223, and the electric motor can be in transmission connection with the driving shaft 1223 through a walking speed reducer 1222. It can be understood that in other embodiments, the second rotating driving member 1221 can also be configured as a rotating cylinder or the like.

[0061] As shown in the figure, Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown in the figure, in an embodiment, the carrying unit 10 further comprises a control module 14 and a damping mechanism 15, the control module 14 is installed on the frame body 11 through the damping mechanism 15 and is respectively in electrical connection with the walking wheel mechanism 12 and the clamping arm mechanism 13, and the damping mechanism 15 can drive the control module 14 to adjust the position of the control module 14 relative to the frame body 11 in the height direction of the frame body 11. That is, the carrying unit 10 can use the control module 14 to control the specific work of the walking wheel mechanism 12 and the clamping arm mechanism 13, and when the carrying unit 10 walks, the damping mechanism 15 can be used to damp and buffer the assembly of the control module 14 on the frame body 11, so as to improve the stability of the electrical connection between the control module 14 and the walking wheel mechanism 12 and the clamping arm mechanism 13, thereby ensuring the stability and control precision of the carrying unit 10 when working. Here, the control module 14 is respectively in electrical connection with the second rotating driving member 1221 in the walking wheel mechanism 12 and the first rotating driving member 1321 in the clamping arm mechanism 13.

[0062] As shown in the figure, Figure 6 , Figure 7As shown in the drawings, in an embodiment, the damping mechanism 15 comprises a mounting bracket 151 and a plurality of connecting assemblies, the mounting bracket 151 is mounted on the frame body 11 through the plurality of connecting assemblies for carrying the control module 14. Wherein each connecting assembly comprises a screw rod 152, a spring 153, a nut 154 and a gasket 155, the screw rod 152 is fixed on the frame body 11, the part of the screw rod 152 penetrating through the mounting bracket 151 is screwed with the nut 154, the spring 153 is sleeved on the screw rod 152 and respectively abuts against the gasket 155 and the frame body 11, so that the connecting assembly can elastically support the mounting bracket 151 by the spring 153, so that when the frame body 11 vibrates during the movement of the carrying unit 10, the control module 14 installed on the mounting bracket 151 vibrates together, and in this process, the spring 153 can play a role of buffering and damping for the mounting bracket 151.

[0063] As shown in the drawings, Figure 8 As shown in the drawings, in an embodiment, the vehicle handler 100 further comprises a pull rod 21, the pull rod 21 is arranged across the two frame bodies 11 and is respectively connected with the two frame bodies 11 in a sliding manner, for guiding and supporting the two frame bodies 11. So that the two carrying units 10 can save the structure of front and rear driven wheels and side guide wheels, and play a role of reducing cost.

[0064] As shown in the drawings, Figure 10 , Figure 11 As shown in the drawings, in this embodiment, the frame body 11 is fixedly installed with a sliding connection piece 22, and the pull rod 21 penetrates through the sliding connection piece 22 and is connected with the sliding connection piece 22 in a sliding manner. That is to say, the pull rod 21 can be connected with the frame body 11 in a sliding manner through the sliding connection piece 22. Wherein the sliding connection piece 22 is fixed to the frame body 11, and the sliding connection piece 22 is in sliding fit with the pull rod 21, and as preferred, the sliding connection piece 22 can be a sliding guide rail or a sliding bearing.

[0065] As shown in the drawings, Figure 8 As shown in the drawings, in an embodiment, the vehicle handler 100 is respectively installed with a locking mechanism 30 on each carrying unit 10, the locking mechanism 30 can act on the part of the pull rod 21 extending out of the sliding connection piece 22, for controlling the locking / unlocking of the pull rod 21 on the corresponding frame body 11; and when the two locking mechanisms 30 lock the pull rod 21 on the corresponding frame body 11 respectively, the spacing between the two carrying units 10 is locked. It should be noted that the two carrying units 10 in the vehicle handler 100 of the present application are respectively used for clamping the front wheels and the rear wheels of the vehicle to jointly complete the transportation of the vehicle; of course, the working principle of how the above-mentioned two carrying units 10 work together and move synchronously can adopt the conventional mode of the existing vehicle handler, which will not be described here.

[0066] As can be seen from the above, when the vehicle transporter 100 of this application is working, it uses two locking mechanisms 30 to mechanically lock the pull rod 21 to lock the distance between the two transport units 10. This ensures the synchronicity of the movement of the two transport units 10 and prevents the vehicle tires from slipping off the transport units 10 when the vehicle transporter 100 is transporting the vehicle. This improves the transport efficiency of the vehicle transporter 100 and reduces costs.

[0067] It should be noted that, since the locking mechanism 30 and the corresponding parts of the pull rod 21 for locking after the distance between the two transport units 10 in the vehicle transporter 100 of this application are all located on the frame body 11, they do not occupy the space between the two transport units 10. This allows the minimum distance between the two transport units 10 when the vehicle transporter 100 is working, where the two frame bodies 11 of the two transport units 10 are abutting against each other. This allows for a wider range of adjustable distances between the two transport units 10 in the vehicle transporter 100, accommodating a wider range of vehicle models with different wheelbases. Here, the minimum clamping distance between the front and rear wheels of the vehicle transporter 100 when working can reach 1880mm, and the maximum can reach 3400mm.

[0068] like Figures 8 to 10 , Figure 12 As shown, in one embodiment, the pull rod 21 has a plurality of fixing holes 211 sequentially opened along its length; correspondingly, the locking mechanism 30 includes a sprocket 31, a lock head 32, and a drive assembly 33. The sprocket 31 is rotatably mounted on the frame body 11, and the sprocket teeth 311 on the sprocket 31 can engage with the fixing holes 211; the lock head 32 is connected to the drive assembly 33, and the lock head 32 can enter the cavity 312 enclosed between two adjacent sprocket teeth 311 on the sprocket 31 under the drive of the drive assembly 33, for circumferentially limiting the sprocket 31 to the pull rod 21 and locking the pull rod 21. In other words, the locking mechanism 30 can engage with the sprocket teeth 311 on the sprocket 31 and the fixing holes 211 on the pull rod 21 through a circumferentially limiting engagement, thereby controlling the locking / unlocking of the pull rod 21. During this process, only the opening / closing control of the drive assembly 33 is required, thus automating the control of the distance between the two transport units 10. Here, when the sprocket 31 rotates on the frame 11, the sprocket teeth 311 on the sprocket 31 can sequentially engage with the fixing holes 211 on the pull rod 21 along the length of the pull rod 21.

[0069] like Figure 9 , Figure 12As shown, in one embodiment, the lock head 32 includes a limiting rod 321, and the lock head 32 can circumferentially limit the sprocket 31 to the pull rod 21 through the limiting rod 321; correspondingly, a sprocket fixing bracket 313 is fixedly installed on the frame body 11, the sprocket 31 is rotatably installed in the sprocket fixing bracket 313, the sprocket fixing bracket 313 is provided with a slot, the slot is connected to the cavity 312; and when the limiting rod 321 circumferentially limits the sprocket 31 to the pull rod 21, the limiting rod 321 can engage with the slot. In other words, the upper limit rod 321 of the lock head 32 can be driven by the drive assembly 33 to engage in the slot of the sprocket fixing frame 313 and move along the depth direction of the slot until it moves into the upper cavity 312 of the sprocket 31. During this process, the bottom of the slot can be used to limit the movement of the limit rod 321, so that the sprocket fixing frame 313 can provide support for the circumferential limit of the limit rod 321 on the sprocket 31, thus ensuring the stability of the lock head 32 when locking the sprocket 31.

[0070] like Figure 9 , Figure 12 As shown, in one embodiment, the drive assembly 33 includes a telescopic drive member 331 and a push rod 332. The lock head 32 is connected to the telescopic rod 3311 of the telescopic drive member 331 via the push rod 332. When the drive assembly 33 is working, the telescopic drive member 331 can drive the lock head 32 towards the sprocket 31 under the transmission of the push rod 332. During this process, the push rod 332 serves as an extension transition. Here, the telescopic rod 3311 and the push rod 332 can be connected via a pin 301. The telescopic drive member 331 is electrically connected to and controlled by the control module 14. Specifically, the telescopic drive member 331 can be an electric push rod, which can be fixed to the frame 11 via an electric push rod mounting bracket 3312. It is understood that in other embodiments, the telescopic drive member 331 can also be a hydraulic push rod, a telescopic cylinder, etc. It should be noted that the push rod 332 can be slidably mounted on the frame 11 via a sliding bearing 303.

[0071] like Figure 9 , Figure 12As shown, in one embodiment, the drive assembly 33 further includes an elastic element 333, which is pre-compressed and installed between the push rod 332 and the lock head 32. The push rod 332 can push the lock head 32 towards the sprocket 31 via the elastic element 333. This utilizes the elastic deformation of the elastic element 333 to buffer the movement of the lock head 32 towards the sprocket 31, preventing damage to the telescopic drive element 331 due to obstruction. Here, the lock head 32 can be limited to the push rod 332 by a fixing screw 302 that passes through the lock head 32 and is threadedly connected to the push rod 332. Correspondingly, the elastic element 333 is fitted onto the fixing screw 302. It should be noted that the elastic element 333 in this embodiment is configured as a compression spring. Of course, those skilled in the art will recognize that the elastic element 333 can also be configured as a rubber sleeve or a highly elastic mating component.

[0072] like Figure 9 , Figure 12 As shown, in this embodiment, the lock head 32 can extend and retract relative to the horizontal center line of the sprocket 31 under the drive of the telescopic drive member 331, so that the lock head 32 can make adaptive adjustments relative to the sprocket 31 under the drive of the push rod 332. Once the upper limit rod 321 of the lock head 32 just abuts against the sprocket tooth 311 of the sprocket 31, when the telescopic rod 3311 continues to drive the push rod 332 to push the lock head 32, the lock head 32 can extend and retract at the front end of the push rod 332 using the elastic member 333. During the operation of the vehicle transporter 100 in transporting the vehicle, or during the operation, if there is a slight movement difference between the two transport units 10, the sprocket 31 will continue to rotate at an angle until the sprocket 31 is locked by the upper limit rod 321 of the lock head 32. This ensures that the deviation range of the distance between the two transport units 10 in the vehicle transporter 100 after adjustment is about 13 mm. The lock head 32 can enter the cavity 312 enclosed between two adjacent sprocket teeth 311 of the sprocket 31 and lock the sprocket 31 circumferentially.

[0073] In summary, when the vehicle transporter 100 of this application retrieves a vehicle, the two transport units 10 can enter the bottom of the target vehicle through their respective walking wheel mechanisms 12. When the clamping arm mechanisms 13 on the two transport units 10 are respectively aligned with the front and rear wheels of the target vehicle, the telescopic drive component 331 of the locking mechanism 30 on each transport unit 10 is activated under the control of the corresponding control module 14. The upper limit rod of the push lock head 32 is engaged in the slot of the sprocket fixing frame 313 and circumferentially locks the sprocket 31. Using action and reaction forces, the sprocket 31 can be locked to the frame body 11 through the sprocket teeth 311, thereby locking the two transport units 10. Afterward, the clamping arm mechanisms 13 on the two transport units 10 can open from the frame body 11 under the control of their respective control modules 14 to clamp the front and rear wheels of the target vehicle. Then, the walking wheel mechanisms 12 on the two transport units 10 are activated again, driving the target vehicle to move together.

[0074] In addition, this application also provides a multi-level parking garage, including the vehicle transporter 100 described above.
