[0002] An electric bicycle controller is a device used to control the operation of an electric bicycle. It is usually composed of a microprocessor, a circuit board, and various sensors. The main function of the controller is to receive signals from the battery and other sensors, and then control the motor speed and torque output based on these signals to achieve functions such as acceleration, braking, and driving mode of the bicycle. The controller can also monitor parameters such as battery power, speed, mileage, etc., and provide relevant information to the rider through a display or other means.

The lifting arm mechanism 6 includes a long arm 61 and a hydraulic rod 62. The hydraulic rod 62 is bolted to the lower inner side of the fixed frame 4. The output shaft of the hydraulic rod 62 is bolted to the long arm 61. The crossbeam 81 is bolted to the long arm 61. At the top of the arm 61, the hydraulic rod 62 is turned on to extend or shorten its output shaft, which can drive the long arm 61 to move up and down, and at the same time can drive the crossbeam 81, the cylinder 82 and the rotating drum 91 to move up and down to change the height. The lifting arm mechanism 6 also includes a vertical column 64, which is bolted to the top of the connecting seat 1. Both sides of the long arm 61 are bolted with sliding sleeves 63, and the sliding sleeves 63 are slidably connected to the surface of the vertical column 64. During the lifting process, the long arm 61 can drive the sliding sleeves 63 to slide up and down along the surface of the vertical column 64, thereby increasing the stability of the long arm 61 during the up and down movement.

[0037] The blocking assembly 54 includes a vertical cylinder 541, a vertical groove 542 and a connecting frame 544. The vertical groove 542 penetrates and is opened in the vertical direction of the vertical cylinder 541. The top of the vertical groove 542 extends to the surface of the top of the vertical cylinder 541, and the bottom of the vertical groove 542 extends to the surface of the bottom of the vertical cylinder 541.

When the long arm 61 is at a high position, the vertical rod 5411 and the inclined plate 5412 are at a relatively high position, and at this time, the inclined surface of the relatively thick part of the inclined plate 5412 contacts the roller 549 The first spring 5410 is a compression spring. The reaction force of the first spring 5410 acts on the surface of the roller 549 through the connecting plate 547 and the fixing plate 548, which makes the roller 549 fit on the surface of the inclined plate 5412. Restricted by the surface of the inclined plate 5412, the through hole 546 on the surface of the movable plate 545 and the vertical groove 542 are misaligned. The movable plate 545 blocks the vertical groove 542 to prevent the high-pressure gas inside the gas storage tank 53 from flowing out before the work starts. During the descent of the long arm 61, the roller 549 can move along the surface of the inclined plate 5412. At the same time, the inclined plate 5412 The thinner portion of the surface contacts the roller 549 and no longer restricts the roller 549. At this time, under the action of the first spring 5410, the connecting plate 547 and the movable plate 545 are driven to move. The movable plate 545 penetrates into the interior of the horizontal groove 543 and aligns the through hole 546 with the vertical groove 542, so that the vertical tube 541 is in an open and closed state. Therefore, the long arm 61 is at a high position and the vertical tube 541 is closed, and the long arm 61 is at a low position and the vertical tube 541 is opened to supply air.

The turntable 86 is fixed on the surface of the rotating drum 91. A plurality of blades 87 are welded on the surface of the turntable 86. The number of blades 87 is several and they are distributed in a ring array on the surface of the turntable 86.

[0039] The rotating arm mechanism 9 also includes a ring body 92, a second spring 93 and an exhaust hole 910. The ring body 92 is welded to the upper inner side of the rotating drum 91. One end of the second spring 93 and the ring body 92 are fixed to each other, and the other end of the second spring 93 is fixed to the movable plug 94. The second spring 93 is a tension spring, which can generate an upward pulling force to the telescopic column 95. In a non-working state, part of the telescopic column 95 is located in the rotating drum 91. The exhaust hole 910 is provided below the surface of the rotating drum 91. The movable plug 94 at the top of the telescopic column 95 is located slightly higher than the exhaust hole 910. A magnet 99 is fixed to the bottom of the rotating column 98 for adsorbing the fixing bolts.

The surface of the connecting seat 1 is also provided with a through groove 810 for the first hose 89 and the second hose 917 to pass through.

[0040] The ejection mechanism 7 includes a movable sleeve 71, a movable column 72, an ejection plate 73 and a movable long rod 74. The movable sleeve 71 is arranged through the bottom of the connecting seat 1, and the top of the movable sleeve 71 extends to the inside of the storage groove 3. The movable column 72 is slidably connected to the inner wall of the movable sleeve 71, and the ejection plate 73 is bolted to the top of the movable column 72. The movable long rod 74 is bolted to the bottom of the long arm 61, and the movable long rod 74 penetrates the connecting seat 1 and is slidably connected to the penetration point, which enables the movable long rod 74 to slide up and down along the inner wall of the connecting seat 1. The bottom end of the movable long rod 74 is bolted with a cross plate 75. When the long arm 61 is at a high position, the movable long rod 74 is also at a high position, and the cross plate 75 at the bottom end can support the movable column 72 at a relatively high position. At this time, the ejection plate 73 is located above the storage groove 3.

[0041] During operation, the air pump 51 is first turned on, and the high-pressure gas generated by it enters the interior of the gas tank 53 through the gas pipe 52. An electronic pressure gauge 57 is also installed on the surface of the gas tank 53. The probe end of the electronic pressure gauge 57 is located on the inner side of the gas tank 53. The electronic pressure gauge 57 is electrically connected to the processing module 10, and the processing module 10 is electrically connected to the air pump 51. The electronic pressure gauge 57 monitors the air pressure in the inner cavity of the gas tank 53 and feeds it back to the processing module 10 until the air pressure in the gas tank 53 is 2-4 MPa, which is equivalent to 2-4 kg of force, and the air pressure is greater than the atmospheric pressure. The processing module 10 controls the air pump 51 to turn off. When the air pressure in the gas tank 53 is lower than 2 MPa, align the bolts to be installed with the four rotating columns 98, so that the hexagonal socket at the top of the bolt is aligned with the rotating The rotating column 98 is then inserted into the hexagon socket and the bolts are adsorbed and fixed by the magnet 99. Then the electric vehicle controller to be assembled is covered with a box cover and placed on the top surface of the ejector plate 73. Then the hydraulic rod 62 is turned on, and its output shaft extends to drive the long arm 61 to descend. Then the long arm 61 drives the cylinder 82, the rotating cylinder 91, and the rotating column 98 to descend, and at the same time drives the movable long rod 74, the vertical rod 5411 and the inclined plate 5412 to follow and descend. In the process of the movable long rod 74 descending, the cross plate 75 also descends accordingly, and the ejector plate 73 and the movable column 72 that lack support descend, and the electric vehicle controller enters the interior of the storage slot 3. Then the long arm 61 continues to descend, and the ejector plate 73 contacts the bottom of the inner wall of the storage slot 3 and no longer descends, while the cross plate 75 The movable column 72 is then out of contact with the movable column 72. The surface of the vertical column 64 is also bolted to a limit plate 65, and the outer diameter of the limit plate 65 is larger than the inner diameter of the sleeve 63. The sleeve 63 contacts the surface of the limit plate 65, which stops the long arm 61 from descending. At the same time, the rotating column 98 and the bolt stay above the electric vehicle controller, and the bottom end of the bolt is close to the box cover of the electric vehicle controller, and the bolt hole is installed on the surface of the box cover; at the same time, during the descent of the inclined plate 5412, the through hole 546 on the surface of the movable plate 545 is aligned with the vertical groove 542, so that the vertical cylinder 541 is in an open state, and the high-pressure gas inside the gas tank 53 enters the first hose 89 and the second hose 917 through the connecting pipe 55 and the first interface 56 respectively. After passing through the first hose 89, the high-pressure gas The high-pressure gas enters the first connecting pipe 88, and then passes through the box body 85 and the outlet pipe 84 into the cylinder 82. Under the action of the internal and external pressure difference, the high-pressure gas tends to move outward. The high-pressure gas passes through the cylinder 82 to push the blades 87 and the turntable 86 to rotate. The turntable 86 drives the rotating cylinder 91, the telescopic column 95 and the rotating column 98 to rotate, thereby providing power for the rotating cylinder 91, and drives the bolts under the rotating column 98 to rotate together. At the same time, the high-pressure gas entering the second hose 917 on the other side passes through the second connecting pipe 916, the third interface 915, the second short tube 914, the second interface 913, the first short tube 912 and the pipeline rotating connector 911 into the rotating cylinder 91. The high-pressure gas passes through the ring body 92 and pushes the movable plug 94 and the telescopic column 95 to move downward.As a result, the telescopic column 95 and the rotating column 98 rotate and move downward, and the second spring 93 is in a stretched state. Then, the bolt follows the rotating column 98 to descend and rotate, and enters the threaded hole on the box cover to tighten the bolt. The assembled electric vehicle controller box cover uses M8 or M5 bolts, and it takes about 3-7N.m of force to tighten the bolt. The thrust generated by the high-pressure gas is sufficient to overcome the static friction between the threads, so that the bolt can smoothly enter the threaded hole on the surface of the box cover. During the process of tightening the bolt, the movable plug 94 continues to descend, and then the movable plug When the telescopic column 95 and the rotating column 98 are lowered to a position lower than the exhaust hole 910, the high-pressure gas is directly discharged from the exhaust hole 910, and will not continue to force the telescopic column 95 and the rotating column 98 to descend, thereby avoiding excessive downward pressure to damage the bolts or the box cover. The bolts are already in a tightened state, and the telescopic column 95, the rotating column 98 and the rotating drum 91 above are stuck. The rotating disk 86 and the blades 87 in the cylinder 82 no longer rotate, and the air no longer flows. The gas in the box body 85 is saturated, and the gas enters the rotating drum 91 from another second hose 917 and is discharged from the exhaust hole 910 to release the pressure, and also avoid rotation. After the column 98 and the rotating drum 91 are stuck, they continue to generate torque force under the influence of the gas pressure thrust, which may damage the bolts. In addition, the use of gas pressure to generate thrust can also avoid over-tightening of the bolts. Then the hydraulic rod 62 can be opened to shrink its output shaft to drive the long arm 61, the cylinder 82, and the rotating drum 91 to rise, so that the rotating column 98 is separated from the bolts. The long arm 61 drives the vertical rod 5411, the inclined plate 5412, and the movable long rod 74 to rise with them, which not only makes the vertical cylinder 541 closed again and stops discharging high-pressure gas, but also drives the movable long rod 74 to move up the horizontal plate 75. The arm rises and contacts the top of the movable column 72. The horizontal plate 75 pushes the movable column 72 and the ejector plate 73 to rise, and the assembled electric vehicle controller is ejected to the outside of the storage slot 3, which is convenient for loading and unloading. In the absence of air pressure, the telescopic column 95 is pulled back to the inside of the rotating drum 91 under the action of the second spring 93. During the whole process, the arm replaces the manual tightening of the bolts by the staff, and tightens four groups of bolts synchronously, which saves time and effort and is more efficient. At the same time, during the process of tightening the bolts, it can also provide protection to prevent excessive tightening and downward pressure from causing damage to the bolts or the box cover.
