DETAILED DESCRIPTION
[0020] The present invention will be further described below in conjunction with the accompanying drawings.
[0021] like Figure 1-Figure 4 As shown, an automatic guided vehicle drive module mechanism includes a mounting module 100, a travel drive module 200 and a steering drive module 300; the mounting module 100 is connected by a travel module mounting plate 110 and a steering module mounting plate 120 through screws, and the upper surface of the travel module mounting plate 110 and the lower surface of the steering module mounting plate 120 are correspondingly provided with ball grooves, and the balls are embedded in the ball grooves; the travel drive module 200 is arranged on the travel module mounting plate 110, and the steering drive module 300 is arranged on the steering module mounting plate 120;
[0022] The walking drive module 200 includes a walking drive motor 210, a reduction drive wheel, a walking shock-absorbing block 230 and a swing bearing; the driving wheel is also a part of the reducer, and the reduction and driving wheels are integrated and connected to the driving motor. The walking drive module 200 includes a first reduction drive wheel 500 and a second reduction drive wheel 600. The first reduction drive wheel 500 and the second reduction drive wheel 600 are connected to walking shock-absorbing blocks respectively. The walking shock-absorbing blocks are provided with a first swing bearing 700 and a second swing bearing 800 with protruding mounting bearings. The first swing bearing 700 and the second swing bearing 800 are connected with a swivel connecting block 400 respectively; the steering drive module 300 and the walking drive module 200 are connected via a swivel connecting block 400.
[0023] The steering drive module 300 includes a rotary gear 310, a rotary reduction gear 320, a rotary power gear 330 and a steering drive motor 340. The steering drive motor 340 serves to reduce speed and provide rotary power. The rotary gear 310 has ball grooves and ball travel steering contacts on the upper and lower surfaces. The rotary power gear 330 is mounted on the steering drive motor 340. The rotary reduction gear 320 and the gear shaft are connected and mounted on the steering module mounting plate 120. The rotary reduction gear 320 is distributed left and right to form a gear train. The steering drive motor 340 is connected to the motor mounting member and mounted on the steering module mounting plate 120.
[0024] Working principle: When the travel drive motor 210 is working, it transmits power to the travel drive reducer 220, and the travel drive reducer 220 drives the reduction drive wheel. The first reduction drive wheel 500 and the second reduction drive wheel 600 form a driving force through the travel drive reducer 220, driving the entire module to move. When the road surface is uneven during the movement, the first swing bearing 700 and the second swing bearing 600 can swing up and down, so that the first reduction drive wheel 500 and the second reduction drive wheel 600 are always in contact with the ground and have grip. The travel module mounting plate 110 is connected to the automatic guide The frame of the vehicle is connected to the steering wheel, which plays a role in driving the guide vehicle to run; when the automatic guided vehicle turns or turns around, the steering drive motor 340 works, and the steering drive motor 340 transmits power to the two rotary reduction gears 320 through the rotary power gear 330 in the form of gear transmission. The arrangement of the two rotary reduction gears 320 on both sides of the rotary power gear 330 makes the transmission more stable; the rotary reduction gear 320 drives the rotary gear 310 to rotate, and the rotary gear 310 contacts the upper ball of the walking module mounting plate 110 and the lower ball of the steering module mounting plate 120, and can rotate freely. The rotary gear 310 transmits the rotating power to the mounting shafts of the first swing bearing 700 and the second swing bearing 800 respectively through the rotary connection block 400, thereby driving the entire walking drive module 200 to turn, and the rotary function can make the entire walking drive module 200 rotate at any angle. It is fixed in a closed form on the steering module mounting plate 120, which can effectively reduce the influence of dust on the gear system, and it can be easily disassembled by fixing with fasteners.
