RU2342279C2 - Folding accumulator vehicle - Google Patents

Abstract

FIELD: transport.

SUBSTANCE: invention refers to folding three-wheeler with electric motor. Folding accumulator vehicle contains two frames capable of movement one in another during folding and unfolding. Rear wheel contains electric motor attached to it. Seat is located over wheel. Fixing devices secure rigidity of vehicle in folded and unfolded condition. Front frame is supported by two wheels of bigger diameter and rear wheel is twice less in diameter than front wheels, but rear wheel is wider than front wheels. Front frame covered by net serves as a carrier, it contains shelf for basket with drop-side or for child's seat. Handlebars' post is inclinable to secure pull of brake cable and simultaneous switch-off of electric motor.

Description

Foldable battery vehicle is a light, cheap, simple, low-maintenance vehicle on three wheels for distances of 20-25 kilometers.

The Cayman Segway battery powered vehicle has a gyroscope system and a mini-computer that stabilize the rider a hundred times per second, which stands on a platform between two wheels. The closest analogue is a folding motorcycle disclosed in RU 2141908 C1. It contains two frames that have the ability to move one into another during folding and layout. The rear wheel contains an electric motor, the seat is located above the rear wheel. Two locks provide rigidity to the vehicle when folded and unfolded.

To increase the use of battery vehicles in the streets, it is proposed to improve the design of the brake drive. When folded, the vehicle can be used as a bag on wheels of 508-610 mm, which easily overcomes the steps of a multi-storey residential building. This unit is simple to manufacture and cheap. It can have both manual and foot brakes. When unfolded, it is reliable in difficult road conditions. The front frame, covered with mesh, is a roomy trunk. All vehicle parts are mass-produced, including an electric motor in a wheel.

A folding battery vehicle is proposed, comprising two frames that are capable of moving one into another during folding and folding. The rear wheel contains an electric motor, the seat is located above the rear wheel. Locks provide rigidity to the vehicle when folded and unfolded. The tool contains three wheels, two large-diameter wheels carry the front frame, the rear wheel is more than half the diameter of the front wheels, and the rear wheel is wider than the front wheels. The front frame is covered with a net, acts as a luggage carrier, contains a shelf for a basket having a folding end wall, or for a seat for a child. The steering rack above half the height has the possibility of deviation to ensure the tension of the brake cable and at the same time turn off the electric motor. The tool has a foot brake, there is a handle behind the seat.

The design of the brake drive from the steering column allows you to respond faster. The vehicle is easy to manufacture. The frame and wheels protect the front man, the design allows you to take a portable generator or spare batteries with you. When folded, the vehicle can be used as a pram. In case of obstacles, when the continuation of the path is possible only on foot, the vehicle can be driven like a bag on wheels, without even folding.

Figure 1 shows the front frame of the vehicle.

Figure 2 shows the rear frame of the vehicle containing the steering wheel and rear wheel.

Figure 3 shows the movement of the frames one after the other during folding and layout.

Figure 4 shows the adaptation of the vehicle for agricultural

works.

Figure 1 reflects the elements of the vehicle - 1. The front frame of the vehicle with two wheels with a diameter of 508-610 mm 2. Battery. 3. Internal threads on the rear wall of the frame. 4. Shelf for a basket or seat for a child. 5. Foot brake that can fold. 6. Mesh basket with one folding end wall. 7. Seat for the baby.

Figure 2 reflects the elements of the vehicle - 8. The steering wheel. 9. Resistor (electric motor control). 10. Reverse (electric motor control to ensure reverse). 11. The brake cable. 12. The wire going to the wheel-electric motor. 13. Handle for driving a vehicle as a bag on wheels, located on the steering wheel when folded. As well as a handle located behind the seat on the transverse base of the clips. 14. Locking nut for folding steering column. 15. Thread for the nut on the base of the steering column. 16. Tube rigidity of the frame structure. 17. Clamps that provide structural rigidity when folded and unfolded. 18. Thrust bearings, one rear bearing at the rear wheel, two at the locks. 19. The main tube connecting the two end walls of the frame in the clips. 20. The thread of the retainers at both ends and corresponds to the internal threads of the front frame. 21. Cable eight, so that the direction was adequate to turn the steering wheel. 22. Pulleys for a cable. 23. The cable clamp eliminates slipping. 24. Corrugation for the hands.

The rear frame moves in the front according to the principle of a matchbox, only both components have end walls. The front wall of the rear frame with the sleeve for the steering column is located between the front and rear walls of the front frame, its loss is excluded. During unfolding, the reverser is engaged in reverse gear, the front wheels are braked by the foot brake and the resistor is activated for low speed. The vehicle is folded out and locked with two locks. At the corners of the end walls there are spots made of rubber or plastic.

A lightweight model with only one latch and shorter frames can be used for compactness. Figure 3 (second row) shows the leg supports in front of the front frame and front wheels with an arrangement in the form of the letter A for greater stability. To do this, the side walls of the front frame are tilted and there are grooves for the deflecting axis from below. (see figure 3, the third row).

Figure 4 shows the elements of the working model. 1. The front frame of the corners and channels. 14. A nut a clamp of a folding rack of a wheel. 16. Two tubes of rigidity of a design of a back frame. 18. The persistent bearing of a back wheel. 23. The cable latch. 25. Split sleeve. There are two of them - one in the middle of the rear wall, the other exactly behind the left front wheel and a few millimeters in front. When the rear wheel strut is rearranged, the voltage of the steering cable in it remains the same. 27. A channel of a slightly small profile, which moves freely in the channel of the front frame. Channel bars are turned by profiles against each other. 28. Internal thread m 12 with the ends of the axis. 29. The latch of the rear frame in the front and intermediate position. To do this, holes are made at equal distances on the corners of the front frame as on the channels of both frames to shorten the length of the unit.

The inner diameter of the split sleeve of the steering column is the same as that of the other two bushings 25, which allows you to remove the seat, stick in the steering column and the transport can become a motor block. In addition to the first electric motor, a second electric motor can be applied above the rear wheel with a chain transmission to it. The front left wheel has an asterisk with a diameter of two less than the rear, for this the rear wheel is exactly two times smaller in diameter and the front frame is raised above the axle to the height of the fork section, the thickness of the pulley and the thrust bearing. The batteries will be in the space of the front frame above the axis, the tops will not break. Folding the vehicle, in the presence of a private house, is not relevant, and the device in the working position can stand in the yard under a canopy. On days when a day feeds a year, a portable generator can be used.

The classic model can be used as a pram; the scooter stops when the tilt of the steering wheel is tilted onto itself. In the unfolded position, the front frame can be used as a trunk, the bottom and side walls of which are covered with mesh.

The light version has leg supports in front of the front frame and can slide along the bushings to the frame, they are used as a brake for folding and folding.

In a heavy model, the second motor is located on the channels of the rear frame, the seat is possible with a back. The front frame with the rear is fixed with bolts m 12 with nuts, for this purpose exactly matching holes with a diameter of 13 mm are made on the walls of both frames.

In the light and medium models, the batteries are nickel-metal hydride or lithium; the heavy version is equipped with lead-acid batteries. The vehicle has a charger.
