RU194050U1 - ELECTRIC DRIVE TO ROLLER SKATES - Google Patents

Abstract

This utility model relates to sports and entertainment equipment. Joins the frame of the roller skate and serves to move the athlete on asphalt and other solid flat surfaces using electromotive force. The essence of this utility model is as follows: on the electric drive frame (6), which is attached to the standard frame (10) of the roller skate, is located drive wheel (5) at a certain distance (7) above the road surface. Above the drive wheel (5) is an electric motor (1), which transmits torque to the drive wheel (5) through a belt drive (2). In the waist bag (11) there is a battery and a speed controller that controls the electric motor (1). In the athlete’s hand is the control panel (12), with which the athlete gives commands to accelerate or brake the speed control, which in turn controls the electric motor (1), through power wires (14) that go along the leg, outside or hidden under clothing . In the event of battery exhaustion, breakdown / failure of any electric drive unit or at will, the athlete can move in the usual way using muscle strength. Or, for movement, he can combine muscular strength with electromotive force at any time and in any combination without the need to change anything in the settings. 5 ill.

Description

Field of technology: the utility model relates to sports and entertainment equipment. It is used for relaxation, entertainment or moving on flat hard surfaces with the help of electromotive force.

The level of technology. The most similar is the patent of utility model RU 127648 U1 IPC А63С 17/00, publication May 10, 2013, in which the standard drive wheel is in constant engagement with the road surface, and the torque is transmitted to it by an electric motor having notches on the shaft. A notched shaft is pressed against the wheel and spins it. The disadvantages of this device are:

1. Increased wear of the drive wheel from contact with the pressed shaft and the road surface.

2. Due to p. 1, the diameter of the drive wheel decreases rapidly and traction is lost.

3. The possibility of comfortable movement of muscle power only if the motor shaft is disconnected from the wheel, otherwise the electric motor will slow down the rotation of the wheel.

Disclosure of a utility model. Essence. The main idea of this utility model, unlike other analogues, is the unstable coupling of the drive wheel (5) with the road surface, which gives rise to a number of positive features described below. The main idea also concerns the possibility of easy and quick installation of an electric drive on almost any roller skates without interfering in their design.

The advantages of a variable drive. The drive wheel (5) is installed at a certain distance (7) above the road surface, being slightly higher than the other wheels. Thereby is achieved:

1. The ability to move on roller skates in the usual way, using muscle strength, and combine it with electromotive force at any time and in any combination without the need to change anything in the settings. When riding in the usual way using muscular strength, the electric drive does not slow down the movement of roller skates and practically does not interfere with both the movement and the performance of various elements and tricks.

2. Security. If you accidentally press the acceleration button on the control panel, breakdown of equipment or jam the acceleration button in the pressed position, the athlete will not control the movement uncontrolled, as the athlete can always put the roller skate on the standard wheels in a position convenient for him, and the drive wheel (5) will rotate idling, remaining at a certain distance (7) above the road surface.

3. Maximum simplicity, reliability and ease of construction.

In the athlete’s hand is the control panel (12). The control panel (12) has a built-in sound signal, a strobe light and a flashlight for safety and convenience of movement in the dark. The supplied acceleration and braking signals from the remote control are transmitted via a signal wire (13) to the speed controller located in the waist bag (11). There is also an assembly of lithium batteries. For safety, the belt of the waist bag (11) has quick-release fasteners so that in case of strong heating or fire of the battery, quickly unfasten it from the body. The control panel (12) is powered by a low voltage of 5 volts coming from the speed controller, as well as a sound signal, a flashlight, a strobe light are fed from it. In turn, the speed controller, which received the signal for acceleration / braking, transmits impulses from the battery through power wires (14) coming from the waist bag (11) through the belt, along the leg above the clothes or to the electric motor hidden under it (1). Some speed controllers have a regenerative braking function. The electric motor (1) is located behind the roller skate above its heel. An additional aluminum electric drive frame (6) is mounted on the standard frame (10) of the roller skate, which is attached to the standard frame (10) in the holes (9) designed to install the axles of the wheels of the roller skate, without the need to make changes to the design of the roller skate. The electric drive frame (6) is attached by replacing the standard short bolts with extended ones. For compatibility with various roller skates, special elongated slots (8) were made in the frame of the electric drive, so that it would be possible to install the electric drive on roller skates with different distances between the axles (9) of the wheels. Behind the last full-time wheel, the drive wheel (5) is mounted slightly higher than the others so that it is at a certain distance (7) above the road surface and does not touch the last full-time wheel. The drive wheel (5) has a gear pulley (3), through which torque is transmitted through a belt drive (2) from an electric motor (1) mounted above the drive wheel (5). Heat from the operation of the electric motor (1) under load is effectively removed and dissipated by an aluminum frame (6). By loosening the axle bolt (4), it is possible to adjust the height (7) of the drive wheel (5) above the road surface, install the gear pulleys (3) of different diameters and the belt tension (2). It is also possible to adjust the height of the electric motor (1) within small limits for installing electric motors of different diameters.

Exercise. The frame of the electric drive (6) is made of aluminum alloy for efficient heat removal from the electric motor (1). The drive wheel (5) is taken from roller skates or a scooter. The most suitable diameter is 100 mm. A wheel of a smaller diameter will wear out faster and it will be more difficult to choose a gear ratio, since the gear pulley (3) on this wheel will need to be made too large in diameter, and it can touch the road surface when turning with an inclination.

Act. To begin the movement, the athlete presses the drive wheel (5) to the road surface, putting the electric roller on the heel and pushing it forward a little, presses the acceleration button on the control panel (12). Acceleration begins. The moment of acceleration is shown in Photo 1 and Photo 2. After speeding up, the acceleration button is released, the leg is placed in the usual riding position and then the athlete moves on the coast at will, or pushing in the usual way with the help of muscular strength. If it is necessary to accelerate yet, the athlete puts his foot on the heel again and repeats the steps described above. If it is necessary to slow down the speed, it slows down either in any usual way, or puts the electric roller on the heel, pressing the drive wheel (5) against the road surface, presses the brake button on the control panel (12) and the speed regulator starts to brake the motor.

The technical result of this design of the electric drive is versatility when driving on electric traction or muscular strength, safety, simplicity of design and reliability due to a rigidly mounted drive wheel (5) located at a certain distance (7) above the road surface.
