[0002] Electric tricycles are three-wheeled vehicles used for transporting goods or people, powered by batteries and driven by electric motors. They utilize large-capacity tubular, left- and right-lined, deep-discharge, traction-type batteries, capable of withstanding long periods of continuous discharge. The batteries can maintain their capacity for two years of normal use. The motors in electric tricycles utilize DC series-excited traction-type brushed or brushless motors with internal speed-regulating and boosting mechanisms, ensuring robust output power and resisting damage during normal use.

[0014] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention. Example 1

[0015] The electric tricycle seat bucket lifting device proposed in this embodiment includes a hollow fixed base 11 with a predetermined capacity. The fixed base 11 is characterized in that a lifting unit, a lifting bracket 6, and a guide screw 10 are disposed within the hollow housing of the fixed base 11. The guide screws 10 are multiple and symmetrically distributed along the inner wall of the hollow chamber of the fixed base 11. The guide screws 10 are interconnected with the lifting unit via the lifting bracket 6. The lifting bracket 6 is connected to the seat bucket assembly 1, which is hollow, has a predetermined capacity, and is wrapped around the fixed base 11. The lifting unit includes a hydraulic lift 7 and a lifting switch 8. The hydraulic lift 7 is fixedly disposed within the hollow housing of the fixed base 11 and is electrically connected to the lifting switch 8 via a signal line 9. The working surface of the seat bucket assembly 1 is provided with a through hole of a predetermined working size, and the lifting switch 8 is disposed through the through hole of the seat bucket assembly 1. The lifting bracket 6 is connected to the guide screw 10 via a guide sleeve 3. The guide sleeve 3 is slidably connected to the guide screw 10, allowing for sliding adjustment within a predetermined range along the guide screw's operating surface. A connecting lug 2 is provided at a predetermined operating position on the inner wall of the hollow receiving chamber of the seat bucket assembly 1. The lifting bracket 6 is connected to the seat bucket assembly 1 via a pin 4 and a split pin that penetrate through the connecting lug 2. Multiple connecting lugs 2, pins 4, and split pins 5 are provided. Example 2

[0016] Based on Example 1, the hydraulic lift 7 and the guide screw 10 are both fixed on the fixed base 11, the top of the hydraulic lift 7 is connected to the lifting ear 2, and the lifting bracket 6 is assembled in sequence through the pin 4, the cotter pin 5 and the connecting lifting ear 2, thereby being fixed to the seat bucket assembly 1.

[0017] Based on the above embodiment, the working process of the present invention is as follows: when height adjustment is required, the driver presses the lifting switch 8, which is transmitted to the hydraulic lift 7 through the signal line 9, and the hydraulic lift 7 moves up or down in height. Since the top of the hydraulic lift 7 is connected to the lifting bracket 6, the hydraulic lift 7 drives the lifting bracket 6 to move up and down, and the lifting bracket 6 is connected to the seat bucket, thereby achieving the purpose of ultimately controlling the lifting of the seat bucket by operating the lifting switch 8; during the lifting process, the guide sleeve 3 makes up and down linear motion along the guide screw 10, controlling the position of the seat bucket assembly 1 to not deviate front, back, left, and right. The hydraulic lift 7 has a self-locking device inside, which effectively locks the comfortable position without deviation.

[0018] The self-locking device on the inner wall of the hydraulic lift 7 described in this application can be any existing latching structure, which is prior art and will not be described in detail in this application. The telecommunication connection method between the lift switch 8 and the signal line 9 and the hydraulic lift 7 can refer to the circuit connection method between switches and devices in the prior art, which is prior art and will not be described in detail in this application.

[0019] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.
