DETAILED DESCRIPTION
[0022] Example 1:
[0023] like Figure 1-8 In the invention, a double-clamping position passenger car transporter is provided, comprising a frame 1, with walking wheel steering wheel mechanisms 6 provided at both ends below the frame 1, the frame 1 is further provided with two parallel forward arms 2 to form a U-shaped structure with one end open with the frame 1, and each forward arm 2 is provided with a forward arm support wheel 4 at one end away from the frame 1, and the forward arms 2 are further provided with a first clamping mechanism 3 and a second clamping mechanism 8 arranged at intervals, each of the first clamping mechanism 3 and the second clamping mechanism 8 including a fixing frame 301, and the fixing frame 301 is provided with at least two spaced-apart clamping rods 302, which can be rotated relative to each other to be parallel to each other to support the vehicle tires.
[0024] The open end of the U-shaped structure forms the front end of the frame 1, used to lift the vehicle. Initially, the two clamping rods 302 are parallel and rest against the inner side of the front extension arm 2. The frame 1, equipped with a battery, control system, and wireless communication module, can automatically or remotely move to one end of the vehicle's drive wheel and engage the fork. When the first and second clamping mechanisms 3 and 8 approach the vehicle's front and rear tires, the clamping rods 302 rotate horizontally to clamp the two tires from the front and back, lifting the four tires from their bases and transporting them to the transport vehicle 7.
[0025] In the preferred embodiment, the front extension arm 2 includes a fixed section 204 and a telescopic section 201, a linear cavity 202 is provided at the end of the fixed section 204, a guide rod portion 203 is provided at the end of the telescopic section 201, the linear cavity 202 and the guide rod portion 203 are slidably plugged in, and the second clamping mechanism 8 is provided on the telescopic section 201.
[0026] The linear cavity 202 is a rectangular cross-section cavity, and the guide rod portion 203 has a rectangular cross-section to prevent the telescopic joint 201 from rotating.
[0027] In a preferred solution, each fixed joint 204 is provided with a linear drive device 9 , and a driving end of the linear drive device 9 is connected to the telescopic joint 201 .
[0028] The linear drive device 9 can be a linear servo electric cylinder. A cylinder rod connecting block 901 is provided on the side wall of the telescopic joint 201 . The cylinder rod of the linear drive device 9 is locked on the cylinder rod connecting block 901 by a nut.
[0029] The linear drive device 9 can adjust the telescopic joint 201 to extend to a set distance to adapt to the wheelbase of different passenger cars.
[0030] In the preferred embodiment, the walking wheel steering wheel mechanism 6 includes a support frame 601, a support frame 601, a rotatable driving wheel 602 is provided at the lower end of the support frame 601, a walking drive motor 603 is provided on one side of the driving wheel 602, and a steering shaft 604 is provided at the upper end of the support frame 601. The steering shaft 604 is rotatably connected to the frame 1, and a steering motor 605 is also provided at the end of the steering shaft 604 on the frame 1. The rotating shaft of the driving wheel 602 is perpendicular to the steering shaft 604.
[0031] The front extension arm support wheel 4 is a driven wheel, which is located close to the first clamping mechanism 3 and can rotate with the drive of the walking wheel steering wheel mechanism 6. The walking drive motor 603 and the steering motor 605 are reduction motors, which drive the support frame 601 to turn relative to the frame 1, and the walking drive motor 603 drives the driving wheel 602 to rotate.
[0032] In the preferred solution, a clamping rod rotating shaft 303 is provided at one end of the clamping rod 302, a clamping drive motor 304 is provided on the fixed frame 301, and the shaft end of the clamping drive motor 304 is connected to the clamping rod rotating shaft 303. Two transition shafts 307 are also provided between the two clamping rods 302 on the fixed frame 301. Synchronous wheels 305 are provided on the transition shafts 307 and each clamping rod rotating shaft 303. Each clamping rod rotating shaft 303 and each transition shaft 307 are driven by a synchronous belt 306. A rotatable gear set 309 is also provided in the center of the fixed frame 301, and each gear of the gear set 309 is connected to the transition shaft 307 through a magnetic coupling coupling 308.
[0033] The clamping drive motor 304 is a reduction motor with a brake.
[0034] The gear set 309 comprises two meshing external gears.
[0035] The first clamping mechanism 3 and the second clamping mechanism 8 utilize a dual-drive structure, namely, two clamping drive motors 304, each controlling the swing of its own clamping rod 302. To enhance the reliability of the first clamping mechanism 3, a transmission mechanism links the two clamping rods 302. This prevents a single motor failure from causing one clamping rod 302 to stop rotating, potentially leading to tire slippage. To prevent the two motors from malfunctioning during commissioning or in the event of a malfunction, a magnetic coupling 308 is incorporated into the transmission mechanism. If a force imbalance occurs on both sides and exceeds a set value, the transmission mechanism disengages, protecting the motors.
[0036] In a preferred solution, vehicle position detection devices 5 are provided on both sides of one end of the frame 1 close to the opening of the U-shaped structure.
[0037] The two vehicle position detection devices 5 at the front end of the frame 1 are cameras, millimeter wave radars or laser radars, etc., which can detect the vehicle outline and posture. The vehicle position detection devices 5 are electrically connected to the controller and battery in the frame 1.
[0038] Example 2:
[0039] An intelligent transporter for loading and unloading passenger cars without releasing the handbrake of the passenger cars mainly includes a frame, a running wheel and steering wheel mechanism, a clamping mechanism, a wheelbase adjustment mechanism, a detection system, and a battery system.
[0040] The frame mainly provides rigid support and fixing conditions for the walking wheel steering wheel mechanism, clamping mechanism, wheelbase adjustment mechanism, detection system, battery system, driven wheel, etc., and its front end is composed of two left and right extending arms.
[0041] The travel wheel and steering wheel mechanism primarily consists of a drive motor, a steering wheel motor, a steering wheel reducer, a driving wheel, and a support frame. The drive motor directly drives the driving wheel, enabling the intelligent transporter to move forward and backward. The steering wheel motor and the steering wheel reducer work together to drive the driving wheel, which then enables the intelligent transporter to turn and move.
[0042] The clamping mechanism is composed of four sets of clamping arms. The two clamping rods of each set of clamping arms can achieve a clamping action of about 90 degrees on the passenger car tire and a horizontal opening action of 180 degrees under the drive of a clamping motor.
[0043] The wheelbase adjustment mechanism is housed within two extension arms, each equipped with a wheelbase adjustment motor, a wheelbase adjustment reducer, a lead screw, and a lead screw nut. The lead screw nut is connected to the two front clamping arms, which are driven by the wheelbase adjustment motor to move the two front clamping arms forward and backward.
[0044] The intelligent transporter is equipped with a detection system that can detect parameters such as the length, width, wheelbase, parking angle on the ground, and net width of the transport vehicle's compartment. This enables the intelligent transporter to accurately clamp the passenger car on the ground and accurately park it on the transport vehicle.
[0045] The smart carrier is equipped with a battery system to provide power input conditions for the motors of the smart carrier.
[0046] The detection system monitors the external environment, monitors the position and operating status of the intelligent transporter in real time, and controls the operation of the various motors based on this information. The battery system provides power to the motors. The wheelbase adjustment mechanism automatically drives the two front gripping arms in a linear motion based on the vehicle's wheelbase as determined by the detection system, ensuring that the spacing between the front and rear gripping arms matches the vehicle's wheelbase.
[0047] The travel wheel steering mechanism, driven by the drive motor, can drive the intelligent transporter forward and backward in a straight line on the horizontal plane. The steering wheel motor and the steering wheel reducer can drive the active wheel of the intelligent transporter to rotate within the range of ±90°. Combined with the action of the drive motor, the intelligent transporter can easily turn and move.
[0048] The clamping mechanism drives the two clamping rods in the clamping arm and the clamping rods to rotate synchronously under the action of the clamping motor and the clamping reducer, realizing the clamping action of about 90° and the horizontal opening action of 180° of the clamping rods.
[0049] Loading Process: The passenger car is parked in a designated open space at the rear end of the transport vehicle, either by AGV or manual operation. The vehicle's parking brake is applied. The intelligent transporter's detection system identifies the vehicle's length, width, wheelbase, and parking angle, feeding this information back to the wheelbase adjustment mechanism. Upon receiving the vehicle's wheelbase information, the wheelbase adjustment mechanism activates, automatically driving the two front clamping arms to move linearly, ensuring the spacing between the front and rear clamping arms matches the vehicle's wheelbase. The steering mechanism receives feedback from the detection system, activating the steering motor and drive motor, automatically aligning the intelligent transporter to face the vehicle. The intelligent transporter then drives forward, aligning the center of the clamping mechanism 5 with the center of the vehicle's tires. The clamping mechanism's clamping motor activates, driving the clamping rods and their synchronous rotation to clamp the four tires, ensuring they are lifted off the ground to a certain height. The drive motor begins to propel the intelligent transporter, gripping the passenger car onto the transporter until it reaches the parking position and stops. The intelligent transporter then controls the clamping motor to rotate and retract the clamping rods, securing the passenger car. A worker enters the transporter compartment from the side, secures the tires, and then exits the transporter. The drive motor then drives the intelligent transporter backward until it is completely clear of the transporter. This completes the loading process.
[0050] Unloading Process: The intelligent transporter's detection system identifies the vehicle's net width, the vehicle's length, width, wheelbase, and parking position within the vehicle, and feeds this wheelbase information to the wheelbase adjustment mechanism. Upon receiving the vehicle's wheelbase information, the wheelbase adjustment mechanism automatically drives the two front clamping arms to move linearly, aligning the distance between the front and rear clamping arms with the vehicle's wheelbase. Upon receiving this information from the detection system, the steering motor and drive motor of the running wheel mechanism activate, automatically aligning the intelligent transporter to face the vehicle. The intelligent transporter then drives forward, aligning the center of the clamping mechanism with the center of the vehicle's tires. A worker enters the vehicle's compartment from the side, unties the tires, and then exits the vehicle. The clamping motor of the clamping mechanism activates, driving the clamping rods and levers to rotate synchronously, clamping the four tires to a certain height, clearing them from the vehicle's floor. The drive motor begins to drive the intelligent transporter to grip the passenger car off the transport vehicle until it is clamped to the designated area. The intelligent transporter rotates and retracts the clamping rods and clamping bars, placing the passenger car securely in the vehicle. Unloading is now complete.
