Description

Motor-assisted propulsion system for street vehicles

The present invention relates to an electric motor power assisted propulsion system, and more particularly to an electric motor power assisted propulsion system applied to a vendor.

Traditionally, vendors have often overcome the overall weight of the vehicle in order to move vehicles filled with items to be sold to a particular location for sale.

With an average of 300 meters per day and a total of 600 meters, the speed of the street car is about 12 meters per minute, and the moving distance is 600 meters per day. The total time required for the vendor is 50 minutes.

Therefore, we need a device that can greatly reduce the power and time required for people to move a street vendor.

Therefore, the purpose of the present invention is to propose a motor power assisted propulsion system that can greatly reduce manpower.

According to the concept of the present invention, the motor power assisted propulsion system includes a body assembly, a powertrain, a pair of first wheels, and at least one second wheel.

According to the concept of the present invention, the body assembly of the motor power assisted propulsion system includes a frame, a drive shaft, and a differential, and the powertrain is mounted on the body assembly and includes a motor and a power source.

Moreover, the powertrain may further include: a speed handle, a switch, and a controller of the brushless DC motor electrically connected to the motor, the power source, the speed handle, and the switch.

1 is a perspective view showing the motor power assisted propulsion system of the present invention; and FIG. 2 is a view showing a state of use of the motor power assisted propulsion system shown in FIG. 1 installed in a vendor.

The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments.

As shown in FIG. 1, in accordance with an embodiment of the present invention, a motor power assisted propulsion system 1 includes a body assembly 2, a powertrain 3, a pair of first wheels 5, and at least a second wheel 6.

As shown in FIG. 1, the body assembly 2 of the motor power assisted propulsion system 1 includes a frame 21, a drive shaft 23 pivotally coupled to the frame 21, and a differential 25.

Referring to Figure 1, in the present embodiment, the rectangular frame 21 is made of stainless Made up of steel components. A pair of stainless steel round rods are pivotally coupled to the frame 21 to act as a drive shaft 23, and each drive shaft 23 is coupled to the differential 25. The differential 25 is coupled to the motor 31 (described in detail later).

Referring again to Figure 1, the powertrain 3 is mounted to the body assembly 2 and includes a motor 31, a power source 33, a speed knob 35, a switch 37, and a controller 39 for the brushless DC motor. As shown in Fig. 1, in the present embodiment, the motor 31 is a brushless DC motor, and the power source is composed of four 12-volt batteries connected in series to provide 48 volts of electric power to drive the motor 31. The speed handle 35 can be mounted to any position in the motor power assisted propulsion system 1 where the user can construct. When the system turns, the user controls the controller 39 of the brushless DC motor to adjust the speed of the vehicle. The motor 31, the power source 33, the rotational speed handle 35, the switch 37, and the controller 39 of the brushless DC motor are electrically connected together to form a circuit.

The motor power assisted propulsion system 1 includes a pair of first wheels 5, wherein each wheel 5 is disposed at an end of each of the drive shafts 23; and at least one second wheel 6 pivotally coupled to the frame 21. In the present embodiment, the number of the second wheels 6 is two, and the pair of second wheels 6 are steerable and pivotally connected to the frame 21 in parallel with the pair of first wheels 5.

When in use, it is only necessary to remove the wheel of the existing vendor and transport it to the frame 21 of the motor-assisted propulsion system 1 of the present invention and fix it, as shown in FIG. 2 .

In addition, the motor power assisted propulsion system 1 may include a brake handle (not shown) provided at a suitable location.

After testing, the motor vehicle with the motor power assisted propulsion system 1 The speed is 30 meters / minute, and the movement time required for 600 meters only takes 20 minutes. Compared with the traditional street vendor, the utility model of the motor power assisted propulsion system 1 of the present invention can be reduced by 30 minutes.

In other words, the operator can open an additional 30 minutes a day. Assume that you work 26 days a month, work 8 hours a day, with a daily turnover of 12,000 yuan, an average of 1,500 yuan per hour, and save 30 minutes will bring an additional 750 yuan to the operator. If you multiply 750 yuan/day by 26 working days, you will receive an additional income of 19,500 yuan per month for the operator, with a revenue growth rate of 6.25%.

As stated above, the present invention successfully achieves the above objectives.

However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification, All are within the scope of this new model.
