Abstract

FIELD: mechanical engineering.

SUBSTANCE: reclined track electric scooter contains a frame which has a track unit driven by an engine, a battery with electric motor control elements, speed and brake control knobs mounted on the battery case, and a driver's bed, a spring and two wheels on it are installed on the rear frame. The frame consists of front and rear parts connected by a hinge with an axis of rotation. The axis of rotation allows the frames to rotate relative to each other in a horizontal plane, making it possible to control the direction of movement. The track propulsion unit with electric motors is rigidly fixed on the front frame. The track unit, together with the front frame, can rotate relative to the rear frame.

EFFECT: increased off-road performance.

Description

The present invention relates to tracked vehicles, and more specifically to a personal electric vehicle with a recumbent driver.

There are personal motorized vehicles with caterpillar propulsion. For example, the following analogues of my invention:

1. Patent No. US2009101427A1, IPC А63С 5/08, “MOTORISED PERSONAL TRANSPORT VEHICLE

2. Patent No. US2008017431A1, IPC B62D 55/104, B62D55/14 "PERSONAL SNOW VEHICLE"

The prototype of my invention is "PERSONAL SNOW VEHICLE)) patent No. US2008017431A1, IPC B62D 55/104, B62D 55/14.

It has a front suspension with a ski control unit and a rear suspension on which the caterpillar drive unit is located. The front and rear suspensions are connected by a frame on which the engine with the transmission for the caterpillar mover and the driver's seat are located.

This vehicle can move on snowy terrain, which gives it certain advantages over wheeled vehicles. But there is an urgent need to move also on sands, swamps or on terrain with impenetrable mud, i.e. there is a need for a more versatile off-road vehicle.

The solution to this problem is my invention "Crawler Recumbent Electric Scooter", which is a versatile off-road vehicle that can successfully move both on impenetrable mud, sand and wetlands, and on snow (after simply replacing the rear wheels with skis).

The task to be solved by the claimed invention is to ensure the possibility of movement of the "Crawler Recumbent Electric Scooter" (hereinafter referred to as the "scooter") both in impenetrable mud, sands and wetlands, and in snow.

The technical solution is achieved due to the fact that the frame consists of two frames - front and rear, interconnected by a hinge with an axis of rotation, which allows the frames to rotate relative to each other in a horizontal plane, making it possible to control the direction of movement, and on the front frame is rigidly fixed caterpillar drive assembly with electric motors, which, together with the front frame, can rotate relative to the rear frame under the action of the driver's feet acting on the pedals rigidly fixed to this frame, providing control of the direction of movement, a battery with electric motor control elements (controller, charger and enabling devices, fuse), speed and brake control knobs mounted on the battery case, and the driver’s bed, a spring and two wheels on it are installed on the rear frame.

The driver's feet, fixed on the pedals in the front of the frame, confidently turn the front frame, which, turning in the hinge connecting the front and rear frames, turns the caterpillar mover. The front frame also has a battery with the necessary elements (controller, charger, switch and fuse) and a speed and brake control knob.

A spring is fixed on the rear frame, on which two large-diameter rear motor-wheels (replaced by skis for the snowmobile version), a bed for the driver and a battery for the rear motor-wheels are mounted. The driver's hands are free from direction control, but only control the speed and brake, mounted on a handle mounted on the front battery mounting bracket. It is possible to transfer the speed control to the right pedal and the brake to the left pedal, thus completely freeing the driver's hands.

The device is illustrated by drawings, which do not cover and, moreover, do not limit the entire scope of claims of this technical solution, but are only illustrative materials of a particular case of execution:

"Crawler recumbent electric scooter" according to my invention contains the following elements (Fig. 1, 2, 3, 4, 5):

front frame 1, rear frame 2, hinge 3, caterpillar mover 4, pedals 5a and 5b, driver's bed 6, front battery 7 (with controller, charger, etc.), control handle with brake levers 8a and speed 8b, rear motor-wheels 9 (replaced with skis in the snowmobile version), spring 10, rear battery 11.

In FIG. 7, 8, 9, 10 shows a caterpillar mover (in the general assembly it is designated pos. 4) in various forms, which consists of:

rubber caterpillar 12, drive sprockets 13a and 13b with gear motors 14a and 14b, driven sprockets 15a and 156, support rollers 16, housing 17.

In FIG. 11 shows the "Crawler Recumbent Electric Scooter" in the "Snowmobile" variant. Skis 18 are supplied instead of wheels 9.

The "caterpillar recumbent electric scooter" is arranged as follows: The front frame 1 is made in the form of a square tube made of high-strength aluminum alloy and is connected to the rear frame 2 (of a similar profile and material) using a hinge 3 and can (to perform turns) rotate in a horizontal plane relative to the rear frame 2. On the front frame 1, the caterpillar mover unit 4 is rigidly fixed, which, together with the front frame, can be rotated under the action of the driver's feet turning the pedals 5a and 5b, which provides control of the direction of the scooter.

On top of the front frame 1, a front battery 7 is installed (with elements of electric control of the motor-reducers 14a and 14b of the caterpillar mover). On the rear frame 2 there is a driver's bed 6, a spring 10 with rear motor-wheels 9 of large diameter with a wide tread for better cross-country ability (for example, from an electric bicycle) and a rear battery 11 (with the necessary motor-wheel controls 9). The brake levers 8a and the speed levers 8b are mounted on a bracket attached to the front battery case 7 and can be operated with one hand while the other hand can hold the navigator or photo gun or other things. It is possible to transfer the speed control to the right pedal and the brake to the left pedal, thus completely freeing the driver's hands.

The movement of the “Crawler Recumbent Electric Scooter” according to my invention is as follows:

The driver takes his lying position on the bed 6, puts his feet on the pedals 5a and 5b, rigidly fixed on the frame 1, having special holders for the feet and can turn the frame 1 with the caterpillar mover 4 in a horizontal plane in the hinge 3. The driver starts moving by adjusting speed using the brake lever 8a and speed 8b, this turns on the geared motors 14a and 14b of the caterpillar mover, which are mounted on the shaft of the drive sprockets 13a and 13b. The teeth of these sprockets engage the caterpillar 12 and move it while rotating the driven sprockets 15a and 15b. The sprung support rollers 16 are rolling along the track 12. The rear wheel motors 9 are switched on simultaneously with the gear motors 14a and 14b and create additional traction, contributing to the confident overcoming of obstacles. In the version of the snowmobile with rear skis installed instead of the motor-wheels 9, the need for the rear battery 11 is eliminated.

Therefore, it can be concluded that such a design with a front-mounted crawler assembly and articulated frames provides greater versatility than the prototype design, which allows the “Crawler Recumbent Electric Scooter” to confidently move both on sands, impenetrable mud and wetlands, as well as and over the snow. The low center of gravity gives the scooter much more rollover stability when driving over uneven terrain than a seated rider. Of course, the two drive motors of the track assembly and the two rear wheel motors consume more electrical energy and therefore a rear battery is provided to compensate for the increased electrical consumption.

These properties can be sufficient arguments for its introduction into production and application in various fields of human activity, where high universal cross-country ability is required both in sand, impassable mud and wetlands, and in snow, with noiselessness and secrecy, for example, foresters, rangers, specialists in the protection and monitoring of the ecology of nature in reserves.
