Description

The proposed technical solution relates to the field of mechanical engineering and can be used in vehicle control systems, in particular, as a device that sets the operation mode of power equipment at the command of the driver.

A known controller for controlling a vehicle (RU 2210127 publ. 08/10/2000), comprising a housing, a cover, a handle. In the controller case for driving a vehicle, a shaft is mounted on which a rotor with a ring gear is fixed, a code disk, a disk with a figured groove connected by a handle. The sensor unit is mounted with adjustable position. A field coil, an anchor with a ring gear and a lid are mounted coaxially with the shaft and are mounted rigidly fixed in the controller body to control the vehicle. In the controller housing for controlling a vehicle, a spring-loaded latch with an excitation coil located on the latch housing is installed through a curly groove. The number of teeth of the crown of the anchor is a multiple of the number of teeth of the ring of the rotor.

The disadvantages of this controller are:

- low reliability;

- high energy consumption in working condition;

- large heat emission of the excitation coil;

- large metal consumption;

Closer in technical essence is a controller for driving a vehicle (RU 84620 U1 publ. July 10, 2009), comprising a housing, a control element — a handle with a built-in spring-loaded button and pusher, a sensor unit rigidly fixed to the controller body, a mechanism for fixing the handle positions characterized in that the casing is made of two walls interconnected by means of columns and closed by a casing, the control element is a handle rigidly fixed to a sector mounted between the casing walls, with the possibility of limited rotation and having internal gear engagement associated with the gear of the pinion shaft mounted in the housing wall with the possibility of rotation, with a leash with two magnets fixed to the pinion shaft, and when moving the handle one of the leash magnets is installed alternately opposite each of the N magnets, where N is the number of positions of the handle fixed on the wall of the housing, and the other magnet mounted on the leash is alternately located with a gap opposite each of the N Hall sensors of the sensor block, also closed heated on the wall of the body, and the mechanism for locking the handle in the neutral position is made in the form of a spring-loaded dog mounted in the sector, and a stop rigidly fixed to the wall of the body.

The disadvantages of this controller are:

- low ergonomic indicators;

- a limited number of switching positions;

- lack of clear position fixing;

- mismatch with modern design requirements;

The technical result of the proposed utility model is to improve the ergonomics of the control, the possibility of increasing the number of fixed positions, increasing the clarity of fixing positions, improving the design of the controller.

The essence of the utility model is that the controller contains a housing consisting of two walls interconnected by columns and closed by a casing, the control element is a handle, a sector with internal gearing, a pinion shaft, a handle lock mechanism in the neutral position, containing a spring-loaded stop lever and a pusher and an emphasis rigidly fixed to the body, a mechanism for fixing the positions of the handle, and also a board of the sensor unit with Hall sensors and a magnet. New in the proposed utility model is that in the housing on the bearing there is a sector disk of the mechanism of the handle lock position in the neutral position, with a bevel sector gear, an additional lever and rod are additionally mounted on the axis on the axis, the sector with internal gearing is also made with the sector bevel gear, and the mechanism for fixing the position of the handle contains a step disk with recesses for the roller mounted on the gear shaft, and a spring-loaded lever with a roller is installed on the housing.

Figure 1 presents an example of a structural embodiment of the controller.

Figure 2 presents sections BB and DD controller.

Figure 3 presents sections BB, GD and DD controller.

The controller, an example of the implementation of which is presented in figure 1, consists of springs 1, 36, 40, pusher 2, axles 3, 27, 28. 32, 38, sector bevel gears 4.30, shaft 5, vernier 6, bearings 7 , 14, 16, intermediate shaft 8, walls 9, 12, columns 10, 21, pinion shaft 11, magnet 13, keys 15, stops 17, 26, intermediate lever 18, handle 19, sector disk 20, roller 22, sensors Hall 23, the board of the sensor unit 24, the brackets 25.29, the sector with internal gearing 31, the stepping disk 33, the recesses 34, the lever 35, the casing 37, the thrust lever 39.

In addition, it contains a housing consisting of walls 9 and 17 connected by columns 10 and closed by a casing 37, the control element is a handle 19 connected to the rod 5 and installed in the sector disk 20 with the vernier 6, the handle lock mechanism in the neutral position, containing spring-loaded 1 pusher 2, spring-loaded 40 stop lever 39, an intermediate lever 18 on an axis 28 mounted in a sector disk 20 and a stop 26 mounted on the housing, a transmission mechanism comprising a sector bevel gear 4, a sector with an internal gear with a sector bevel gear 30, mounted on the intermediate shaft 8 and the pinion shaft 11, a grip position fixing mechanism comprising a step disk 33 with recesses 34 mounted on the pinion shaft 11 and mounted on the housing of the spring lever 36 with the roller 35 pressed by the spring 36 and the roller 22 , a device for issuing control signals, comprising a board of a sensor unit 24 with N Hall sensors 23, (where N is the number of positions of the handle 19) mounted on the housing using columns 21 and a magnet 13 mounted on the step disk 33.

The controller operates as follows. Initially, the handle 19 is in the neutral position and is pressed from below through the shoulder of the intermediate lever 18 and the pusher 2 by the spring 1, while the roller 22, mounted on the lever 35, is pressed by the spring 36 to one of the depressions 34 of the step disk 33 and fixes this position, and the spring-loaded end the lever 39 is mounted opposite the stop 26 and locks the handle in the direction of the running positions. To transfer the handle 19 to the running position, the handle is pressed down, the pressing force through the intermediate lever 18 is transmitted to the end of the stop lever 39, pressed by the spring 40, compresses it, removes the lever from the stop 26 and unlocks the handle. When moving the handle from the running position to the brake position through the neutral position, the spring-loaded end of the stop lever 39 slides along the stop 26 and does not impede its movement. In each fixed position of the handle 19, provided by pressing the roller 22 to the depressions 34 of the step disk 33, the magnet 13 mounted on the step disk occupies a position opposite one of the N Hall sensors 23, (where N is the number of positions of the handle 19), the sensor unit board 24, which give appropriate control signals to the traction motors of the vehicle. When installing the handle 19 in a neutral position from the side of the brake positions, the spring-loaded end of the stop lever 39 is installed opposite the stop 26 and locks the handle in the direction of the running positions.

In the proposed utility model, in comparison with the prototype, a bevel gear is additionally introduced for transmitting force from the handle to the output shaft, which, while maintaining the overall height and distance from the top point of the handle to the upper plane of the mechanism, increases the radius of rotation of the handle, which makes the trajectory of the handle more ergonomic and allows you to increase the diameter of the stepper disk to increase the number of positions. In the design of the prototype to fix the position uses the force of mutual attraction of permanent magnets. Due to the presence of a zone of weak mutual attraction of the magnets when they are coaxial, there is no clear fixation of the handle positions. To eliminate this drawback in the proposed utility model, the fixation of positions is achieved by preloading the roller to the recesses of the step disk. The proposed changes also improve the overall design of the controller.
