DETAILED DESCRIPTION

[0022] Example 1:

[0023] like Figure 1-9 In the present invention, an auxiliary transporter for loading and unloading passenger cars includes a frame 1, with walking wheel and steering wheel mechanisms 6 provided at both ends below the frame 1. The frame 1 is also provided with two parallel forward arms 2 to form a U-shaped structure with one end open with the frame 1. Each forward arm 2 is provided with a clamping mechanism 3 and a forward arm support wheel 4. The clamping mechanism 3 includes a fixed frame 301, and the fixed frame 301 is provided with at least two spaced clamping rods 302. The clamping rods 302 can rotate 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 clamping mechanism 3 approaches the vehicle's tire, the clamping rods 302 rotate horizontally to clamp the two tires from the front and back, lifting the bottom of each tire and pushing it onto the transport vehicle 7.

[0025] 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.

[0026] The front extension arm support wheel 4 is a driven wheel, located close to the 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.

[0027] 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.

[0028] The clamping drive motor 304 is a reduction motor with a brake.

[0029] The gear set 309 comprises two meshing external gears.

[0030] The clamping mechanism 3 utilizes a dual-drive structure, with two clamping drive motors 304 each controlling the swing of a respective clamping rod 302. To enhance the reliability of the 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.

[0031] 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.

[0032] 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.

[0033] In a preferred solution, the front outrigger support wheel 4 is provided at the end of the front outrigger 2 away from the frame 1 , and the clamping mechanism 3 is provided between the frame 1 and the front outrigger support wheel 4 and close to the front outrigger support wheel 4 .

[0034] In a preferred solution, the clamping mechanism 3 is provided at the end of the front arm 2 away from the frame 1 , and the front arm support wheel 4 is provided between the frame 1 and the clamping mechanism 3 and close to the clamping mechanism 3 .

[0035] Example 2:

[0036] An intelligent transporter for loading and unloading passenger cars mainly includes a frame, a running wheel and steering wheel mechanism, a clamping mechanism, a detection system, and a battery system.

[0037] The frame mainly provides rigid support and fixing conditions for the travel wheel and steering wheel mechanism, clamping mechanism, detection system, battery system, driven wheel, etc. Its front end consists of two extending arms on the left and right.

[0038] The travel wheel and steering 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.

[0039] The clamping mechanism consists of two sets of left and right clamping arms. Driven by a clamping motor, the two clamping rods in each set can clamp the tire approximately 90 degrees and open it horizontally 180 degrees. The clamping mechanism can be used to clamp either the front or rear tires, depending on the application.

[0040] 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.

[0041] The smart carrier is equipped with a battery system to provide power input conditions for the motors of the smart carrier.

[0042] The detection system is responsible for monitoring the external environment, detecting the position and operating status of the intelligent transporter in real time, and controlling the operation of the various motors based on this information. The battery system is responsible for providing power to the various motors.

[0043] 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 a range of plus or minus 90 degrees. Combined with the action of the drive motor, the intelligent transporter can easily turn and move.

[0044] 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 degrees and the horizontal opening action of 180 degrees of the clamping rods.

[0045] Loading Process: The passenger car is parked in a designated open area at the rear of the transporter, either by AGV or manual operation. The front of the car faces away from the transporter, and the parking brake is applied. The intelligent transporter's detection system identifies the car's length, width, wheelbase, and parking angle, feeding this information to the steering mechanism. The steering motor and drive motor activate, automatically aligning the intelligent transporter to face the car. The intelligent transporter then drives forward, aligning the center of the clamping mechanism with the center of the car's front tire. The clamping motor activates, driving the clamping rod and the clamping rod to rotate synchronously, clamping the front tire to a certain height off the ground. The drive motor then drives the intelligent transporter to hold the car onto the transporter, stopping at the parking position. A worker enters the transporter from the side, applies the parking brake, closes the door, and secures the rear tire. The intelligent transporter controls the clamping motor to rotate and retract the clamping rod. The worker secures the front tire of the passenger car and then leaves the transporter. The drive motor drives the intelligent transporter backward until it is completely clear of the transporter. The loading operation is complete.

[0046] Unloading Process: The intelligent transporter's detection system identifies the truck's net width, the vehicle's length, width, wheelbase, and parking position within the truck. This information is fed back to the travel wheel steering mechanism. The steering motor and drive motor activate, automatically aligning the intelligent transporter with the truck. The intelligent transporter then drives forward, aligning the center of the clamping mechanism with the center of the vehicle's front tire. A worker enters the truck from the side and unties the ropes securing the vehicle's front tire. The clamping mechanism's clamping motor activates, driving the clamping rod and clamping bar to rotate synchronously, clamping the vehicle's front tire and keeping it clear of the truck's floor. The worker enters the vehicle, applies the parking brake, closes the door, unties the ropes securing the rear tire, and exits the truck. The drive motor then drives the intelligent transporter to clamp the vehicle off the truck until it is secured to the designated area. The intelligent transporter then rotates and retracts the clamping rod and clamping bar. The worker enters the passenger car, pulls up the handbrake, closes the door and leaves, and the unloading operation is completed in one go.
