[0021] See Figures 1 to 4 This utility model provides a multi-functional electric three-wheeled sidearm loader, including an electric three-wheeled vehicle body, a sidearm structure, and auxiliary equipment 29. The electric three-wheeled vehicle body is existing technology and includes a frame 1. A front wheel 48 is located on the front side of the bottom of the frame 1, and a drive motor 45 is located at the bottom of the frame 1. The front wheel 48 is driven by the drive motor 45. A rear wheel 36 is located on the rear side of the bottom of the frame 1. From left to right, a brake pedal 15, an instrument panel 3, and a speed pedal 16 are arranged on the front side of the frame 1. The instrument panel 3 is located in the middle of the frame 1, and a steering wheel 7 is located in the middle of the instrument panel 3. The steering wheel 7 controls the steering of the rear wheel 36 through a steering structure. The steering structure is existing technology and can be mechanical or hydraulic steering; its specific structure will not be described in detail here. An instrument 50 and a switch 51 are located on the top of the instrument panel 3. A headlight 53 is located on the front side of the instrument panel 3, and a key switch 22 is located at the top right side of the instrument panel 3.

[0022] The rear of the frame 1 is equipped with a tail box 2 and a lifting arm bracket 4. The tail box 2 is located in the middle of the rear of the frame 1. From right to left, the top of the tail box 2 is equipped with a high / low speed gear shifter 14, a seat 6, and a handbrake handle. The seat 6 is located in the middle of the frame 1. The right side of the top front of the tail box 2 is equipped with a hydraulic operating handle valve block 8. A hydraulic operating handle 9 is mounted on the hydraulic operating handle valve block 8. The bottom end of the hydraulic operating handle 9 is sealed with a dustproof rubber sleeve 10 between it and the hydraulic operating handle valve block 8. The left side of the top front of the tail box 2 is equipped with an electric travel control handle 12 and a handbrake handle 13. The right side of the bottom front of the tail box 2 is equipped with a main power switch 49. The rear of the frame 1 is equipped with a taillight 55, a reversing reminder device 56, and a rear lighting light 57.

[0023] The lifting arm support 4 is located on one side of the top of the frame 1. The side arm structure includes a lifting arm 5, a lifting hydraulic cylinder 24, and an adjusting hydraulic cylinder 26. One end of the lifting arm 5 is movably connected to the lifting arm support 4, and the top end of the lifting arm 5 is movably connected to the top end of the lifting arm support 4 via a pin 28. The other end of the lifting arm 5 extends to the front of the electric tricycle body, and the other end of the lifting arm 5 is movably connected to the bottom end of the auxiliary device 29. The top end of the auxiliary device 29 is connected to the lifting arm 5 via the adjusting hydraulic cylinder 26.

The other end of the lifting arm 5 and the output shaft end of the adjusting hydraulic cylinder 26 are respectively movably connected to the auxiliary attachment connecting seats 30 via a steering universal joint 31 and another pin 28. The setting of the other pin 28 and the steering universal joint 31 facilitates the fixing or separation of the auxiliary attachment 29 from the lifting arm 5 and the adjusting hydraulic cylinder 26, thereby enabling the loader to perform different functions by changing different auxiliary attachments during use, improving the adaptability of the loader. The auxiliary attachment 29 includes buckets, forks, sweepers, lawnmowers, cutters, etc., as found in the prior art.

[0024] The lifting arm 5 is connected to the frame 1 via a lifting hydraulic cylinder 24. Both the top of the frame 1 and the bottom of the lifting arm 5 near the lifting arm support 4 are equipped with cylinder mounting bases 23. The end of the lifting hydraulic cylinder 24 is movably connected to the cylinder mounting base 23 via another pin 28. The lifting hydraulic cylinder 24 is tilted, with its output shaft end located near the side away from the auxiliary device 29. The loader lifts the lifting arm by controlling the extension and retraction of the lifting hydraulic cylinder 24. Adjusting the hydraulic cylinder 26 to be tilted allows its high end to connect to the lifting arm 5. Adjusting the extension and retraction of the hydraulic cylinder 26 changes the angle of the auxiliary device 29.

[0025] The aforementioned lifting hydraulic cylinder 24 and adjusting hydraulic cylinder 26 are both powered by a battery pack to supply power to an electric hydraulic pump. The electric hydraulic pump controls the flow of hydraulic oil through a hydraulic operating handle valve block, supplying the hydraulic oil to the hydraulic cylinders, enabling the hydraulic cylinders to extend and retract. Figure 1As shown, the inner cavity of the tail box 2 is equipped with a hydraulic oil tank 20 and a power battery pack 21. A hydraulic pump motor 17 and a hydraulic pump 19 are provided on one side of the inner cavity of the tail box 2. The inlet end of the hydraulic pump 19 extends into the inner cavity of the hydraulic oil tank 20 through a hydraulic oil pipe. The outlet end of the hydraulic pump 19 is connected to the inlet end of the hydraulic operating handle valve block 8 through a hydraulic oil pipe. The outlet end of the hydraulic operating handle valve block 8 is connected to the cylinder interface 27 of the lifting hydraulic cylinder 24 or the cylinder interface 27 of the adjusting hydraulic cylinder 26 through a hydraulic oil pipe.

[0026] In addition, to improve the stability of the loader, the lifting boom 5 is designed to be wider at the bottom and narrower at the top, such as... Figure 3 As shown, the lifting arm 5 includes a parallel section 58 and an extension section 59. The auxiliary tool 29 is connected to the extension section 59. The end of the parallel section 58 away from the extension section 59 is connected to the lifting arm bracket 4. The adjusting hydraulic cylinder 26 is connected to the parallel section 58.

[0027] Rear wheel 36 Figure 4 As shown, the rear wheel 36 includes two wheel bodies 38, which are connected to the frame 1 via a wheel frame 37. The wheel bodies 38 and the wheel frame 37 are movably connected. The arrangement of the two wheel bodies 38 allows the rear wheel to travel smoothly.

[0029] In summary, this multi-functional electric three-wheeled side boom loader is an improvement on the existing electric three-wheeled loader technology. The installation position of the lifting arm 5 is changed from being installed in front of the frame 1 to being installed on the side of the frame 1, thereby reducing the space occupied by the loader. Before use, the staff connects the appropriate auxiliary tool 29 to the lifting arm 5 and the adjusting hydraulic cylinder 26 according to the requirements. When using this multi-functional electric three-wheeled side boom loader, the power battery pack 21 serves as the power source for the loader. By turning on the main power switch 49 and then controlling it with the key switch 22, the power is connected, and the instruments and equipment of the whole vehicle are powered on. After the loader is powered on, when working, the handbrake handle 13 is released, and the electric travel control handle 12 controls the forward or backward movement of the electric three-wheeled vehicle. The steering wheel 7 controls the steering of the rear wheel 36, the drive motor 45 controls the rotation of the front wheel 48, and the hydraulic operating handle 9 controls the extension and retraction of the lifting hydraulic cylinder 24. The extension and retraction of the lifting hydraulic cylinder 24 causes the lifting arm 5 to be lifted, thereby controlling the lifting of the auxiliary tool 29. The angle of the auxiliary tool 29 is adjusted by using the adjusting hydraulic cylinder 26.
