DETAILED DESCRIPTION

The present invention will be further described below in conjunction with the embodiments.

Please refer to Figures 1-3. The utility model provides an electric bicycle equipped with a pneumatic tool, including a base 1, an adjustment mechanism 2 is arranged on the top of the base 1, and a lifting mechanism 3 is arranged on the upper side of the base 1;

The lifting mechanism 3 includes a mounting rod 9, which is used to connect the connecting plate 7 with the lifting rod 10. A slide groove 11 is provided in the middle of the front wall of the mounting rod 9, and the lifting rod 10 is slidably connected to the inner side of the slide groove 11. The lifting rod 10 can slide up and down inside the slide groove 11. A tooth groove 13 is provided in the middle of the front wall of the lifting rod 10. The tooth groove 13 is meshed with the gear 14. During the rotation of the gear 14, the tooth groove 13 is moved up and down, thereby moving the lifting rod 10 up and down. Mounting plates 15 are fixed on both sides, and a transmission rod 16 passes through the middle part between the two sets of mounting plates 15 and is rotatably connected. The transmission rod 16 rotates synchronously with the gear 14, and the gear 14 passes through and is fixed to the middle part of the outer periphery of the transmission rod 16. A worm wheel 17 is fixed to the right end of the transmission rod 16, and a worm 18 is meshed and connected to the front side of the worm wheel 17. The worm wheel 17 and the worm 18 cooperate to prevent the gear 14 from rotating due to the gravity of the lifting rod 10, thereby keeping the pneumatic screwdriver 12 at a fixed height and not falling.

As further shown in Figures 1, 2 and 3, it is worth specifically explaining that the adjustment mechanism 2 includes a mounting groove 4, which is arranged in the middle of the top wall of the base 1, and a screw 8 is rotatably connected to the middle of the inner side of the mounting groove 4, and a threaded block 6 is threadedly connected to the outer periphery of the screw 8. During the rotation of the screw 8, the threaded block 6 will slide left and right inside the mounting groove 4, and a connecting plate 7 is fixed to the top wall of the threaded block 6. A drive motor 5 is fixed to the middle of the right wall of the base 1, and the output shaft of the drive motor 5 is fixed to the screw 8. The drive motor 5 is a power component of the adjustment mechanism 2.

As further shown in Figure 3, it is worth explaining in detail that the worm 18 passes through and is rotatably connected between two sets of fixed plates 20, and the fixed plates 20 are respectively fixed at the upper and lower ends of the front side of the right wall of the right mounting plate 15, and the fixed plates 20 are used to connect the worm 18 and the mounting plate 15.

This solution has the following working process: when it is necessary to use pneumatic tools to assemble the electric bicycle, first turn the crank 21, and the crank 21 drives the worm 18 to rotate during the rotation of the crank 21, and the worm 18 drives the worm wheel 17 to rotate when the worm 18 rotates. During the rotation of the worm wheel 17, the gear 14 is driven to rotate through the transmission rod 16, and during the rotation of the gear 14, it cooperates with the tooth groove 13 to drive the lifting rod 10 to slide up and down inside the mounting rod 9, and adjust the height of the pneumatic screwdriver 12 to adapt to the maintenance operations at different positions of the electric bicycle. After the height adjustment of the pneumatic screwdriver 12 is completed, start the pneumatic screwdriver 12 and the drive motor 5, and the output shaft of the drive motor 5 rotates to rotate the screw 8, and the rotation of the screw 8 causes the threaded block 6 to move left and right inside the mounting groove 4, so that the bolts can be automatically assembled, eliminating manual operation steps.

According to the above working process, it can be known that with the cooperation of the base 1, the mounting groove 4, the drive motor 5, the screw 8, the threaded block 6, the connecting plate 7 and the mounting rod 9, the electric bicycle can be automatically assembled, eliminating the manual assembly operation and reducing the difficulty of using pneumatic tools. At the same time, with the cooperation of the crank 21, the fixing plate 20, the rotating wheel 19, the worm 18, the worm wheel 17, the transmission rod 16, the worm 18, the worm wheel 17 and the lifting rod 10, the height of the pneumatic screwdriver 12 can be adjusted to stabilize it at a certain installation height without manual control, thereby improving the assembly rate of the electric bicycle.

Further as shown in Figures 1, 2 and 3, it is worth specifically explaining that a rotating wheel 19 is fixed to the top of the worm 18, and a crank 21 is fixed to the middle of the top wall of the rotating wheel 19. The provision of the crank 21 can reduce the difficulty of rotating the worm 18, and the rotating wheel 19, the worm 18 and the crank 21 rotate synchronously.

As further shown in Figure 1, it is worth explaining in detail that a pneumatic screwdriver 12 is fixed to the top middle part of the left wall of the lifting rod 10, and the gear 14 is meshed with the tooth groove 13. During the rotation of the gear 14, the tooth groove 13 will be moved up and down, thereby moving the lifting rod 10 up and down, adjusting the height of the pneumatic screwdriver 12 to make it coincide with the assembly position, replacing manual control of the pneumatic tool.

As further shown in FIG. 1 , it is worth to explain in detail that the mounting rod 9 is fixed at the middle of the top wall of the connecting plate 7 , and the mounting rod 9 moves with the connecting plate 7 moving left and right.

In summary: providing a crank 21 can reduce the difficulty of rotating the worm 18. The rotating wheel 19 and the worm 18 rotate synchronously with the crank 21. During the rotation of the gear 14, the tooth groove 13 will be moved up and down, thereby causing the lifting rod 10 to move up and down, and the height of the pneumatic screwdriver 12 is adjusted to coincide with the assembly position, thereby replacing manual control of the pneumatic tool. The mounting rod 9 moves left and right with the connecting plate 7. The crank 21 is turned. During the rotation of the crank 21, the worm 18 is driven to rotate. When the worm 18 rotates, the worm wheel 17 is driven to rotate. During the rotation of the worm wheel 17, the gear 14 is driven to rotate through the transmission rod 16. During the rotation of the gear 14, it cooperates with the tooth groove 13 to drive the lifting rod 10 to slide up and down inside the mounting rod 9.

The drive motor 5 can be purchased on the market. The drive motor 5 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
