In order to ensure the stability of driving and the convenience of handling, they are generally three-wheeled vehicles, that is, the front wheels provide direction control, and the two One of the rear wheels is designed as a driving wheel, and the other is a driven wheel to form the basis for traveling. In order to ensure that the electric vehicle is turning, the two rear wheels achieve a differential effect (that is, the speed of the inner rear wheel when turning). lower than the outer rear wheel), so that there will be no danger of falling or being unable to turn during the turning process. Therefore, in order to have a differential function between the driving wheel and the driven wheel, there are various complex designs. In addition to increasing the complexity of the mechanism, if the user operates carelessly, there is also a potential danger of tipping over, which needs to be improved urgently. .

The driving wheel or the driven wheel are often unable to cope, so that the situation of overturning is also heard from time to time. Of course, some operators have added shock absorbers to both rear wheels to cope with rough roads. Due to the high manufacturing cost, the price of electric vehicles remains high, making it difficult to popularize them.

Detailed ways

As shown in Figures 1 to 4, the portable electric vehicle of the present utility model is composed of a car body 1, a control device 2, a seat portion 3, a transmission mechanism 4 and a secondary pressure mechanism 5.

Wherein, the vehicle body 1 is a vehicle frame 11 designed through stress structure strengthening, and the exterior is covered with a cover 12 according to its shape, forming the function of shielding parts and straddling the seat. One side of the vehicle frame 11 is pivotally connected with a control device 2 for direction control, while the other side protrudes from a frame portion 13 so that the top is connected with a seat portion 3, while the bottom is for the transmission mechanism 4 described later. And the accommodating and positioning of the secondary pressure mechanism 5. However, the utility model is different from the known technology in that the rear two sides of the vehicle frame 11 are respectively pivotally connected with a driven wheel 14 .

The control device 2 is pivoted to a front wheel 22 with a shaft rod 21 below, and a handle 23 is connected to the top. By turning the handle 23, the front wheel 22 at the bottom can be turned to control the direction of travel. Please refer to Fig. 7 and Fig. 8, there is a fastening part 24 under the shaft 21, by loosening/tightening control of a buckle handle 241, the shaft 21 can be tilted downward with the fastening part 24 as a fulcrum, Or the shaft rod 21 is erected as a basis for storage or travel. In addition, the handle 23 can also be pivotally connected to the top of the shaft 21 by a fastening member 24, and the control of the handle 241 can allow the handle 23 to be rotated and positioned at an appropriate angle (as shown in FIG. 8 ), so that In response to the different body shapes of riders, it is very humanized. Please refer to Fig. 7 again, the top surface of the frame part 13 is provided with a fastener 15, when the riding part 3 is turned down and straddles the pedal of the cover 12, then the shaft 21 is folded down, so that the fastener 15 is buckled. Connected to the handle 23, the storage step is completed, and the packaging volume can be greatly reduced.

As shown in Figure 2 and Figure 6, the riding seat part 3 is arranged on the top of the frame part 13, and a seat 32 is connected above a bracket part 31 for the riding of the rider. The part 3 can be turned down, so that the bottom of the two L-shaped front rods 311 on one side of the bracket part 31 is pivotally connected to the side of the frame part 13, and the top of the two rear rods 312 on the other side is pivotally connected to the end edge of the front rod 311. , and the bottom part is inserted into the rod hole 16 corresponding to the frame part 13, so that the seat 32 is formed in a fixed state as shown in FIGS.

The transmission mechanism 4 is fixed below the frame part 13 of the vehicle frame 11 and between the two driven wheels 14. It is composed of an electric horse 41 and an output device 42, such as turbines, belts, chains or gears. The extended output shaft 421 is pivotally connected with a driving wheel 43. When the motor 41 is powered by a storage battery 44 and started, the rotation of the output shaft 421 of the output device 42 can make the driving wheel 43 start and stop. brake function. Since the driving wheel 43 of the present invention is arranged between the two driven wheels 14, the driven wheels 14 on both sides can be operated at a constant speed or non-constant speed in response to various situations at any time, so there is no need to install any differential mechanism , that is, when the electric vehicle of the present utility model is turning, the danger of toppling or the embarrassment of being unable to turn will not occur.

The secondary pressure mechanism 5 mainly provides that when the utility model is driving, the driven wheels 14 on both sides of the uneven or bumpy road will prop up the driving wheel 43 and suspend it, so that it does not contact the ground and loses the functions of driving and braking. . Therefore, the secondary pressure mechanism 5 is connected with a set of core rod 53 with a compression spring 52 above a brace 51, and the top of the core rod 53 passes through a groove frame 54 fixedly arranged on the frame part 13, so that the brace 51 and the frame 54 clamp the compression spring 52 together. The lower part of the bracket 51 is connected with the output device 42 , and a torsion spring 55 is clamped therebetween, and one movable end thereof is overlapped with the output device 42 . In addition, the output device 42 is straddled and fixed on a U-shaped suspension plate 56, and the inner end of the suspension plate 56 is connected to the fixed frame 17 at the rear of the vehicle frame 11, so that the entire transmission mechanism 4 can move according to the ground state. The secondary pressure mechanism 5 is longitudinally elastically displaced.

Wherein, the purpose that this torsion spring 55 is provided with is, when not riding, the pressure of this torsion spring 55 can absorb the car weight of empty car, makes it unlikely that driven wheel 14 is propped up, and then causes car body to tilt, and guarantees in the There is also a braking function on uneven or bumpy roads. And the purpose that clip spring 52 is provided with is, when riding, due to being subjected to larger weight, and when driving on uneven or bumpy road section, allows drive wheel 43 to be able to rise and fall arbitrarily, keeps contacting with ground forever, and then brings into play start running and stop. The function of the brake, and its various simulated states, are shown in Figure 5A to Figure 5F.

Through the implementation of the utility model, the transmission mechanism and the driving wheel are set between the two driven wheels, and they are suspended on the primary and secondary pressure mechanism. The secondary pressure mechanism makes the driving wheel constantly contact with the ground without causing any damage. Causes the trouble of not being able to drive or braking. In addition, since the driving and braking of the utility model are performed by the driving wheel between the two driven wheels, when turning, the two driven wheels can run at constant or non-constant speeds without any differential mechanism. It is not only simple but also obtains the differential speed effect. Moreover, both the control device and the seating part of the present invention can be turned down for storage or convenient packaging.

What the utility model discloses is only a kind of preferred embodiment, all partial changes or modifications are derived from the technical idea of the utility model and are easily deduced by people familiar with the technology, and all do not depart from the utility model scope of patent rights.
