Description

Electric tricycle capable of automatically contracting and standing by itself

The technical field is as follows: electric bicycles and electric tricycles.

Background art: the conventional electric vehicle is generally only two wheels, has no half-point self-supporting and non-falling capability, can be maintained by speed inertia, can hardly collide with any point to be squeezed and rubbed at the moment, and is really full and full to fall once being collided and heavy once being fallen. The safety problem is always unsolved. Even if the user stops the machine, the user needs to support the ground by two feet immediately, the user needs to put down the feet no matter how dirty and muddy the ground is, the user can only endure the condition of stepping the ground to be dirty, and otherwise the user can lie the ground seriously and cannot imagine the condition. The three-four wheeler is not easy to be popularized. An efficient, reasonable, cheap and feasible scientific scheme is urgently needed to be solved.

The invention content is as follows: a tricycle with permanent automatic contraction function is designed. Firstly, the tricycle has the self-standing and self-stabilizing function, and even if the tricycle is rubbed with each other, the tricycle is extremely crowded and densely runs or is stored, the tricycle cannot topple. The basic damage caused by the fact that a large number of car accidents mainly fall is avoided, and therefore safety is greatly improved. At the same time, at least two rear wheels of the whole vehicle adopt a structure which can be folded automatically at ordinary times and can be released automatically to reset when riding, thus avoiding the defect that the three wheels occupy larger space at ordinary times. The two ends of the axle of two rear wheels are firmly fixed on the wheel cover reinforcing frame plate to form a whole, at least three parallel four connecting rods which are not on the same straight line are manufactured on the wheel cover frame plate, and are connected and fixed on the same corresponding positions on the large-beam rear frame in the upward or forward direction, at ordinary times, the two wheels are tightly attached and reduced by tension springs (side pull and inclined pull), and are pressed and unfolded only when bearing (carrying goods or riding people), even if the two wheels are contracted and attached, the two wheels are grounded, and the two sides of the two wheels are equally supported, so that the two wheels can be basically kept from falling and pushing all the time, the difficulty in lifting the automobile body by force and pressing the support frame in the past is eliminated, and the pushing and pulling displacement are convenient. The frame and the faucet can be made into a middle elastic folding and shrinking structure, so that the space is saved, the crowding is reduced, the strength is improved, and the follow-up management and correction are facilitated. The batteries can be fixed in any space or even in wheels, a larger space in the wheels is generated in a half-shaft mode to place the batteries, and current conduction is carried out through the insulated inner and outer friction plates and the center bar of the shaft.

Description of the drawings: in the figure, 1 wheel, 2 connecting rods, 3 cloth films, 4 beam frames, 5 pin lugs, 6 handlebars, 7 tension springs, 8 extension plates, 9 rainshed, 10 rainshed supporting rods, 11 pull wires, 12 clamping grooves, 13 brake handles, 14 brake wires, 15 front forks, 16 pin rods, 17 wheel covers, 18 batteries, 19 conductive reeds, 20 wheel shafts and 21 front forks. FIG. 1 is a rear view of the rear wheel link structure, with the upper portion in a half-open position, the rear wheel cover being formed as a rectangle with two outer sides extending upward to provide a larger cargo space, and the upward extending canopy frame being also more convenient. FIG. 2 is a simplified illustration of the manner in which batteries are stored in the wheel wells. FIG. 4 is a side view of another embodiment of the whole vehicle, wherein the dotted line on the figure shows that the connecting rod is in a frame shape and rotates laterally, the fixed part of the canopy is connected and supported by movable supporting rods (shown by dotted lines) on the front end and the rear end of the wheel cover, the two rods on the front upper part (top edge) are connected into an L shape, and the canopy is limited forwards and stretched outwards, is closed inwards when falling (the connecting pin shaft deflects), and can tighten the top surface when standing. The rain shed is in three sections, the front section is provided with the connection limit and is pulled down to the center of the tap by the pull wires at two sides to be fixed, the rear section is slightly larger and automatically droops, the three sections are not provided with cross bars, and the folding are not influenced by the outward expansion forming (detailed) of the torsion of the root parts of the bars. And can be connected with the side compartment cloth film into a whole body, and the whole closed compartment and the rainproof awning can be formed by stretching. Fig. 3 is a front view of the front fork of the bicycle, and the top and bottom of the handle are top views, the top end of the handle bar handle is a square tube with a broken bottom and can be sleeved on a front fork big beam top frame, the connecting cross pin 16 is clamped in the long groove 12 to push and clamp the long tube inwards to form a steering of the bicycle, the steering can be pulled outwards, turned over and drooped down to be reduced, and the built-in tension spring is permanently and automatically tightened and positioned. Meanwhile, the extending of the back-rest chair of the card writing board and the development of the folding bed are similar, simple, practical and effective, and the total contribution amount to the long-term accumulated value of the study, work and life of a user is huge.

The specific implementation mode is as follows: the general cold-work plate welding is mainly simple to manufacture, the hardware is made of light and strong steel, the cloth membrane is made of nylon mesh cloth, and the acrylic aluminized cloth is better and can prevent fire and cut by a knife.
