Abstract

A novel electric vehicle, comprising: a housing (100), a vehicle frame (106), a vehicle compartment bottom which covers the vehicle frame (106), and a movement mechanism which is mounted on the vehicle frame (106). A region which the housing (100) and the vehicle compartment bottom enclose to form is a vehicle compartment, a seat being mounted within the vehicle compartment. Driving and braking functions of the electric vehicle are both provided at a middle wheel of front and rear wheels. By means of linkingly controlling the steering of the front and rear wheels respectively, the direction of both the front and rear wheels may be controlled, thereby achieving manipulation at a higher degree of difficulty. A bumper (105) having a large area, which is linkingly associated with the steering of the front and rear wheels, is mounted on the periphery of a vehicle body, and thus once the bumper (105) collides with a surrounding object, a small external force may instantly cause the vehicle to automatically change directions and thereby move away, moreover the external force shock absorbing performance is also greatly enhanced, while impact force may be reduced to prevent the occurrence of violent collisions.

Technical field

The invention relates to the technical field of electric vehicles, and in particular to a novel electric vehicle.

Background technique

Electric vehicles, using electrical energy to transform the kinetic energy of driving the car, have become more and more widely used because of their work without generating exhaust gas, pollution, and clean energy. However, the high-end electric vehicles that are common in the market are generally stable in terms of safety and comfort, and are bulky and costly and unattractive. Therefore, there is a need for a new electric vehicle that is safer, more stable, more comfortable, lighter, more attractive, and more affordable than existing products.

Summary of the invention

It is an object of the present invention to provide a new electric vehicle that is safer, more stable, more comfortable, lighter, more beautiful, and more affordable. The driving and braking functions of the present invention are all provided in the intermediate wheel of the front and rear wheels. Through the linkage control of the front and rear wheel steering respectively, the front and rear wheel directions are controllable, thereby achieving highly difficult control. On the outside of the vehicle body, a large-area guard bar associated with the front and rear wheel steering linkage control is installed. Once it collides with the surrounding objects, the small external force can automatically change the car away from the moment to avoid the occurrence of severe collision. For the design of the front and rear wheel direction control of the car, the direction of the front and rear wheels is finally determined by the manual, automatic (the force that always exists in the positive direction) and the external force. The outer casing is made of a transparent, lightweight and hard material, the shape of the outer casing is similar to the shape of the capsule, and the door is a curved door that is pushed up and down.

detailed description

As shown in FIG. 1 to FIG. 3, in order to effectively reduce the height of the vehicle body, the longitudinal axis of the frame 106 is designed to be flat at both ends and then tilted downward to become horizontal. The damper 103 is selected from the spring damper with moderate elasticity. The left and right ends and the middle portion of the front and rear axles of the frame 106 respectively have slanting downward and parallel shafts 107, and the bearings in the shaft 107 are respectively loaded with the following sides. Two spring dampers 103 and wheels 102 of the fork (Note: "The front and rear axles of the frame" in this specification refer to the cross member of the frame, and the "left and right axles of the frame" refer to the longitudinal beams of the frame). And only the two intermediate wheels below the middle of the front and rear axles have the function of driving and braking, and at the same time play most of the weight bearing effect on the whole body (the middle wheel has a larger size than the left and right wheels). The rotating shaft 107 in the middle of the front axle of the frame 106 extends upward and is fitted with a handlebar 108 to control the front wheel direction. The front and rear wheel steering linkage control device shown in FIG. 3 utilizes the principle of a parallelogram, so that the directions of the front and rear wheels are respectively consistent and the steering is synchronized. As shown in FIG. 2 and FIG. 3, at the same height of the axis of the shaft 113 of the fork of the upper portion of the damper 103, the fork shaft 113 is fixed to the front fork shaft 113 in the forward direction, respectively. The end has a rotating shaft 107 which is perpendicular to the fixed column 109. The rotating shaft 107 is provided with a bearing. The fixing post 109 is connected to the connecting rod 110 of the retaining bar 105 parallel to the front and rear axles of the frame 106 via bearings in the rotating shaft 107. The ends of the fixing posts 109 fixed to the rear of the frame 106 toward the rear of the frame 106 and the ends of the rear axles toward the front of the frame 106 are respectively connected to the left and right axes of the frame 106 to be connected in series. The tension springs 104, and each of the tension springs 104 have no tension when the wheels are in the positive direction (the small dots indicated in the figure are the connection points). As shown in FIG. 1 , since the front and rear ends of the guard bar 105 are oscillated from side to side with the steering of the front and rear wheels, the guard bar 105 is connected to the front and rear ends on both sides of the vehicle body, and cannot be fixedly connected. The way the hollow is the other end of the mouth. The outer guard bar 105 is a high-hardness and elastic curved surface which is slightly outwardly protruded from the upper and lower ends of the middle portion, and includes four movable blocks in front, rear, left and right. In order not to affect the getting on and off the vehicle, the widths of the upper and lower guard bars 105 are narrower and thicker and have a higher hardness. In the direction of the front and rear ends, the guard bar 105 tends to be wider and thinner and wider, and accordingly, the hardness thereof tends to become smaller.

As shown in FIG. 4, the two intermediate wheels 102 are wider and wider than the four side wheels 102, and the corresponding two intermediate wheels 102 are shock-absorbing. The width of the fork of the device 103 is also adapted to accommodate the intermediate wheel 102. The center shaft 113 of the forks of all of the wheel upper shock absorbers 103 extends downward by a length, and the center shaft 113 of the forks of the four side wheels 102 is slightly inclined to the left and right sides so that the side wheels 102 are slightly inclined outward. A set of steering mechanisms is connected to the upper and lower ends of the center shaft 113 of the fork above the six wheels, and the upper and lower layers are completely identical, and are respectively connected to the outer guard bars 105 on both sides.

As shown in FIG. 5, the left and right footrests 111 for controlling the direction of the rear wheel are connected by a rotating shaft which is mounted on the middle shaft of the front portion of the frame, and the bearing has a bearing therein, and the left and right footrests 111 can be folded backwards when not in use. stand up. The horizontal rotation of the left and right foot 111 is used to drive the wire 112 to control the steering of the rear wheel.

The outer casing 100 selects a material which is light in weight and colorless and transparent on the raw material. The shape of the outer casing is a capsule shape, and the height of the upper and lower sides is greater than the width of the left and right sides to reduce the air resistance and better improve the ride comfort of the driver. As shown in FIG. 1 to FIG. 2, the shape can be approximated as a two-hemispherical central cylindrical shape in front and rear, and the middle portion is double-layered and hollow, and an arc-shaped door 101 that is pushed up and down is attached to the interlayer. The door has a circular curved surface from top to bottom, and the front and rear openings on the outer door of the door, so that the doors on both sides can be pushed up to the outside of the outer casing. In the hollow casing on both sides of the door, a track composed of a plurality of small pulleys is installed from top to bottom, so that the door can be pushed up and down along the curved surface of the door. The upper and lower sides of the outer casing 100 and the door 101 are to be covered with a rubber sleeve for waterproof sealing, cleaning and cushioning. The outer casing 100 and the car bottom are fixed to the frame 106.

In addition, to control the pedal in the direction of the rear wheel, in order to avoid the risk of out of control of the car at a higher driving speed, it should be avoided or even prohibited. In order to prevent the car from moving when it stops, adding a handbrake similar to that used in a car can simply solve the problem by simply increasing the control of tightening or relaxing the mechanical brake line. The handbrake is mounted on the center axle at the front of the frame between the left and right foot pedals, and the handbrake line is connected to the front/rear wheel brake line through a small piece of elastic spring. The brake is powered off on the hand brake. In addition to the frame for load-bearing, the whole vehicle should be made of lightweight, high-hardness and elastic plastic material. The weight of the car should be as balanced as possible, and people should sit on the center line as much as possible to maintain the balance of the car's center of gravity. Due to the high power of the motor, a relatively high speed can be achieved while driving. To ensure safe driving, the seat should be equipped with a seat belt and make the ride as comfortable as possible.
