Description

Technical Field

[0001] The utility model relates to the technical field of marine machinery, in particular to an electric outboard motor. Background Art

[0002] The overall structure of the current electric outboard motor is as follows Figure 1 As shown, most of them adopt a structure similar to that of traditional gasoline outboard motors. However, since the drive motor is located at the bottom of the machine, the overall center of gravity of the machine moves downward. When the machine is not in working state and needs to be lifted out of the water, it is difficult to complete the lifting by manpower. Therefore, many electric outboard motor users are unable to lift the machine out of the water when the outboard motor is not needed. This will greatly increase the corrosion rate of the machine and reduce its service life. It will also cause algae and crustaceans to attach to the surface of the impeller and the body, resulting in a decrease in the subsequent operation efficiency of the machine. In addition, the traditional structure is large in size and the express delivery cost is expensive, which cannot adapt well to the express delivery in the current e-commerce era. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide an electric outboard motor which is convenient and labor-saving to lift and has a smaller volume after lifting.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: an electric outboard motor, comprising a main shaft, a base is provided on the upper part of the main shaft, a driving assembly is provided on the lower part of the main shaft, the main shaft is hinged at the lower part of the base, a locking assembly and a lifting assembly are provided on the base, the locking assembly can limit the rotation angle of the main shaft, the lifting assembly comprises a lifting handle and a traction rope, the lifting handle is hinged on the base, and the two ends of the traction rope are respectively connected to the lifting handle and the main shaft.

[0005] In the above technical solution, the locking assembly includes a connecting rod, a spring, a limit pin and a limit plate. The limit pin is installed at the lower part of the connecting rod, the spring is provided on the outer periphery of the connecting rod, and the limit pin can be inserted into one of the multiple limit grooves on the limit plate.

[0006] In the above technical solution, the limiting groove includes a shift groove on one side of the limiting plate and a lift fixing groove on one side of the limiting plate.

[0007] In the above technical solution, a cam handle is provided on the upper part of the connecting rod, and the cam handle can drive the connecting rod to rise and fall when it rotates.

[0008] In the above technical solution, the driving assembly includes a propeller and a motor thereof.

[0009] In the above technical solution, a traction rope fixing seat is provided on the base, and the traction rope passes through the traction rope fixing seat and is fixed to the middle part of the main shaft.

[0010] In the above technical solution, the traction rope is a flexible shaft.

[0011] In the above technical solution, a steering tube is provided on the base, the steering tube passes through the base and can rotate relative to the base, a steering handle is provided on the upper part of the steering tube, the main shaft is installed on the lower part of the steering tube, and the steering tube can drive the main shaft to rotate under the control of the steering handle.

[0012] In the above technical solution, the connecting rod and the spring of the locking assembly are both arranged in the steering tube.

[0013] The technical solution of the utility model has the following beneficial effects compared with the traditional technical means: the utility model shortens the lifting and rotating force arm by about 50% by moving the lifting and rotating point from the upper part to the middle part of the machine and pulling the lifting and rotating through a new traction component. Moreover, since the weight of the upper part of the machine does not participate in the rotating and lifting, the weight involved in the rotation is also reduced by about 40%, so the overall lifting and rotating force is reduced by about 70%, so that the force required for lifting and lifting is smaller and lifting and lifting is more convenient.

[0014] Moreover, the packaging size of the machine has been greatly reduced, which has brought great benefits to the current e-commerce era, especially cross-border e-commerce. It is estimated that it can save more than 30% of logistics and transportation costs. Taking the company's existing 20HP machine as an example, the transportation cost of a machine delivered to Europe is as high as 3,000 yuan. The logistics cost is reduced by 30%, and the advantage of saving 900 yuan in transportation costs is very obvious.

[0015] In summary, the utility model optimizes the structure of the electric outboard motor. When controlling the tilting, the whole machine is not tilted, but the lower part is tilted, making the tilting action more convenient and labor-saving. Moreover, the main shaft is hinged at the lower part of the base. In the tilting state, the main shaft is rotated 90° and attached to the base, similar to the folded state. After tilting, the length direction can be greatly shortened, which is more convenient for storage and transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figure 2 , 3 The limiting groove 441 includes a shift groove on one side of the limiting plate 440 and a tilting and fixing groove on one side of the limiting plate 440.
