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 for position adjustment. 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 76747 U1 publ. September 27, 2008), comprising a housing, a control element, a sensor unit rigidly mounted on the controller body, a locking mechanism consisting of a spring-loaded lever mounted on a carriage with the ability to move his shoulder along the profile bar mounted on the controller body. The carriage locking mechanism is made in the form of a spring-loaded button with a pusher installed in the handle housing. The pusher abuts against the upper part of the rocker arm, mounted rotatably on the carriage strut, and the lower part of the rocker arm is located opposite the free shoulder of the thrust lever, mounted rotatably on the carriage. The spring-loaded end of the thrust lever of the carriage abuts against a stop rigidly fixed to the controller body. The magnet is installed in the carriage body, and in the working position of the controller handle the magnet is located with a gap opposite one of the sensors.

The disadvantages of this controller are:

- low reliability;

- high material consumption;

- large overall dimensions;

- large mass;

- non-dustproof design;

- mismatch with ergonomic requirements;

The technical result of the proposed utility model is to reduce the material consumption, the complexity of manufacturing, reducing the overall dimensions, increasing reliability, bringing it in line with modern ergonomic requirements.

The essence of the utility model lies in the fact that the controller contains a housing, a control element — a handle with a built-in spring-loaded button and pusher, a sensor unit rigidly fixed to the controller housing, and a mechanism for fixing the handle positions. New in the proposed utility model is that the housing is made of two walls interconnected by columns and closed by a casing. The governing body is a handle rigidly fixed to a sector installed between the walls of the housing, with the possibility of limited rotation and having internal gear engagement associated with the pinion of the pinion shaft mounted in the wall of the housing for rotation. A leash with two magnets is fixed on the gear 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 handle positions fixed to the housing wall. Another magnet mounted on a leash is alternately located with a gap opposite each of the N Hall sensors of the sensor block, also mounted on the housing wall. The locking mechanism of 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 housing.

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

Figure 2 presents a section bB controller.

Figure 3 presents a view a and a section GG controller. The controller, an example of the implementation of which is presented in figure 1, consists of screws 1, 2, walls 3, 17, columns 4, 11, bearings 5, 12, pusher 6, buttons 7, springs 8, 23, magnets 9, 15, 16, the casing 10 with a scale 27, the pinion shaft 13, the pin 14, the axis 18, the sector 20 with the stops 19, 22 and the vernier 26, the handle 21, the dog 24, the stop 25, the Hall sensors 28, the board 29, the leash 30. In addition Moreover, it contains a housing consisting of walls 3 and 17 connected by columns 4 with screws 1, a control element - a handle 21 with a button 7, a spring 8 and a pusher 6, a sector 20 with internal gearing, are installed th in the housing with bearings 5. Shaft gear 13, mounted in the wall 17 of the housing with bearings 12, with a lead 30 with magnets 15, 16, rigidly fixed to its end with a pin 14. The sensor unit consists of a board 29 mounted on wall 17 using columns 11, with N Hall sensors 28, (where N is the number of positions of the handle 21). The mechanism for fixing the positions of the handle 21, contains N magnets 9, mounted on the wall 17 and the magnet 16, mounted on a leash 30. The mechanism for locking the handle in the neutral position, contains a dog 24, a spring 23, mounted on the sector 20 and an emphasis 25, mounted on the wall 3 corps.

The controller operates as follows. Initially, the handle 21 is in a neutral position, while the magnet 16, mounted on a leash 30, is against one of the magnets 9, mounted on the wall 17 and fixes this position. The free end of the dog 24 abuts against the stop 25 and locks the handle in the direction of the running positions. To translate the handle 22 into the running position, the spring-loaded button 7 of the handle is pressed. The pressing force through the pusher 6 is transmitted to the spring-loaded end of the dog 24, the free end of the dog is removed from the stop and unlocks the handle. When moving the handle from the running position to the brake position through the neutral position, the free end of the dog 24 slides along the stop 25 and does not impede its movement. In each fixed position of the handle 22, provided by the opposition of the magnet 16 and one of the magnets 9, installed opposite poles towards each other, the magnet 15 mounted on the leash 30, is in position opposite one of the Hall sensors 28, boards 29, which provide the appropriate traction control signals vehicle engines. When installing the handle 22 in a neutral position from the brake positions, the free end of the dog 24 abuts against the stop 25 and blocks the handle in the direction of the running positions.

In the proposed utility model, in comparison with the prototype, where a handle mounted on a carriage and moving along the guides is used as a working body, a joystick type handle is used. The design uses a gear drive, as well as a circular arrangement of fixing magnets and Hall sensors, which can significantly reduce the dimensions and weight of the controller, increase its reliability, as well as perform a dustproof controller that meets modern ergonomic requirements.
