Description

The invention relates to auxiliary devices, mainly passenger cars, in particular to built-in lifting and transporting devices that facilitate maneuvering, including parking, in tight traffic conditions.

The well-known "Method of parking cars and a device for its implementation" (patent RU 2491398 C2, IPC: ЕНН 6/18, published on December 20, 2012 Bull. No. 35).

The device contains an individual lifting mechanism, which is made in the form of rotary uprights installed on the vehicle’s bottom between its wheels, the rotation axes of which are parallel to the longitudinal axis of the vehicle. The racks are equipped with means for adjusting their height and fixing relative to the bottom, and the ends of the racks are equipped with support rollers, the axis of rotation of which is perpendicular to the axis of rotation of the wheels of the car. Means for regulating the height of the racks are made in the form of a screw-nut transmission or other gear transmission, or using a pneumatic cylinder. Moreover, the change in the height of the racks can be carried out both in manual mode and with the help of a drive (using the energy of the car or an individual pump). Means of fixing the racks relative to the bottom of the car are made in the form of a swivel bracket and stop, which do not go beyond the permissible dimensions (clearance) of the car.

For parking, the car is fixed on a lifting device, raising it to a height at which the tire of the wheels does not touch the road surface, tilting the lifting device with the vehicle in the direction of the parking place between adjacent parked cars, moving the vehicle into the parking zone under the action of a rolling force and lowering it with the lifting device parked car until the tires of the wheels with the road surface are fully touched. Unpacking the car is performed similarly in the opposite direction.

The disadvantages of this device are the large energy consumption of the car associated with raising its own weight, the complexity of the design and operation, manual movement of the car during parking is associated with a dangerous exit of the driver on the roadway and serious delays in traffic, in the case of uneven and littered road surfaces, manual movement of the car on rollers small diameter is a time-consuming operation, automation of the device leads to a systematic serious weight load on the car.

It is known "Car parking device" (patent RU 2489282 C2, IPC: B60S 9/215, Pub. September 20, 2012 Bull. No. 26), which is adopted as a prototype of the claimed device. The prototype device is a structure built into the car that allows you to lift all its running wheels above the road. As an electromechanical lifting and lowering system, a worm-rack drive is used in the design. Each support consists of a telescopically fixed element connected and a retractable rod, in the extreme positions of which limit switches are provided. The reciprocating movement of the rod is carried out from a separate reversible electric motor, fed from the on-board network of the car. The auxiliary wheel is pivotally mounted on the vertical axis of the rod, which extends from the fixed part, the auxiliary wheel is lowered onto the supporting surface, lifting the corresponding part of the car. The rotation of the auxiliary wheels by a separate reversible electric motor provides lateral movement of the vehicle without manipulating the steering wheel. To turn or turn the car on a narrow road, the auxiliary wheels rotate on a vertical axis perpendicular to the lines connecting the diagonally arranged wheels. When using the device as a built-in jack, which smoothly lifts and lowers the load on the supporting surface, all safety conditions are met. In order to avoid spontaneous rolling of the vehicle on auxiliary wheels when raising all of its running wheels from the road, an auxiliary wheel brake is provided. The shaft of the low-speed reversible auxiliary wheel drive electric motor is connected to the wheel shaft through an elastic connecting compensating sleeve, which softens the shocks and torque shocks.

The disadvantages of this device are the large energy consumption of the car associated with the lifting of its own weight, the complexity of the design and operation, serious weight load on the car.

The task is to give the car the ability to move in the transverse directions and rotate in place with simpler, lighter and less energy-intensive means.

The technical result of the invention is to simplify, facilitate and reduce the operational energy consumption of the vehicle lateral movement device, which contributes to its mass introduction into mass-produced cars, which in turn provides an increase in the density of vehicle parking on the streets of megalopolises and adjoining territories up to one and a half times with the corresponding release of the carriageway of highways and increase in their throughput.

The technical result is achieved by the fact that the device transverse movement of the vehicle, containing the first and second reversible motors, additionally introduced: command sensor, logical element OR, first logical element AND, first horizon sensor, encoder, first RS-trigger, first power amplifier, first solenoid, second RS-trigger, second power amplifier, third RS-trigger, first polarity switch, second solenoid, vertical sensor, second polarity switch, third power amplifier, second logical lement And, the first gear, the fourth power amplifier, a fourth RS-trigger, the second gear, the second sensor horizon, a third AND gate, the front and rear crutches with bilateral spherical profile, rubberized shoes on the ends,

- moreover, crutches are installed one at a time in the front and rear parts of the car, rotated around the longitudinal axis of the car, lying in the plane of the axles of its running wheels, long enough to turn them in their vertical position into the only reference points on their side of the car, and the first exit bus the command sensor is connected to the input bus of the logical element OR and the input bus of the encoder, the first output and second output of which are connected to the first inputs of the second and third RS-flip-flops, respectively, the second output of the com ND is connected to the first inputs of the first and third logical elements AND, the output of the OR gate is connected to the first input of the first RS-trigger, the output of the first horizon sensor is connected to the second input of the first logical element And, the output of which is connected to the second inputs of the first and third RS- triggers, the output of the second RS-trigger is connected to the first input of the first polarity switch, the second input of which is connected to the output of the fourth power amplifier, the output of the first RS-trigger is connected to the inputs of the first and second amplifiers power, as well as with the first input of the second logical element AND, the output of the first power amplifier is connected to the input of the first solenoid, the output of the first polarity switch is connected to the input of the first reversible motor, the shaft of which is connected through the first gear to the shaft of the rear crutch, the output of the third RS-trigger is connected with the first input of the second polarity switch, the second input of which is connected to the output of the second power amplifier, the output of the second polarity switch is connected to the input of the second reversing electric motor, the shaft of which through the second gearbox connected to the front crutch shaft, the output of the second horizontal sensor is connected to the second input of the third logical element And, the output of which is connected to the second input of the second RS-trigger and the first input of the fourth RS-trigger, the second input of which is connected to the output of the second logical element And the second input of which is connected to the output of the vertical sensor, the output of the fourth RS-trigger is connected to the inputs of the third and fourth power amplifiers, the output of the third power amplifier is connected to the input of the second solenoid.

The technical result in terms of simplifying and facilitating the device of lateral movement of the car is achieved by reducing the number and reducing the length and power of the power transmission in the device. Reducing operational energy costs is achieved through the use of the transverse movement of the car, which does not require at any time in this process the complete lifting of the car above the roadway. Since only the addition of new blocks and connections provides the indicated technical result, and the entire combination of blocks and connections of the claimed device was previously unknown, the proposed technical solution has a patent novelty.

The device operates as follows:

Before turning on the power, the front 27 and rear 24 crutches are in a fixed horizontal position, by entering the spring-loaded rods de-energized, respectively, of the first 8 and second 13 solenoids. When you turn on the power of the device, the first 6, second 9, third 11 and fourth 22 RS-triggers are automatically set to zero. The initial installation circuits in the functional diagram (Fig. 4) are not shown for simplicity. If necessary, make the transverse movement of the car, the driver using the command sensor 1 generates the appropriate command. The command sensor 1 is a four-position switch for generating on the bus its first output a unitary code corresponding to the command selected by the driver, and an independent button for generating a single signal for stopping lateral movement and fixing the crutches in a horizontal position at its second output.

If necessary, make a lateral movement of the car to the right, for example, for parking, the driver generates code 0001 at the first output of command sensor 1, which enters the input bus of the logical element OR 2 and the input bus of the encoder 5. As a result, a single signal is generated at the output of the logical element OR 2 translating the first RS-trigger 6 in a single state. At the same time, zero signals are generated at the first and second outputs of the encoder 5. From the direct output of the first RS-flip-flop 6, a single signal through the first power amplifier 7 turns on the first solenoid 8, through the second power amplifier 10 it enters the second (power) input of the second polarity switch 15 and the first input of the second AND gate 18. When you turn on the rod of the first the solenoid 8 is pulled inward and thus releases the front crutch. At the same time, the zero signals at the first and second outputs of the encoder 5 do not lead to a change in the initial zero states of the second 9 and third 11 RS-flip-flops. Therefore, from the direct outputs of these triggers, zero signals arrive, respectively, at the first (control) inputs of the first 12 and second 15 polarity switches. As a result, a power signal is generated at the output of the second polarity switch 19, which causes the second reversing motor 19 to rotate so that, after transmitting the force through the second gearbox 23, the front crutch 27 rotates clockwise when looking along the direction of the vehicle. At this time, until the front crutch 27 reaches the vertical position, the first reversible motor 16 is at rest due to the lack of a power signal at its input due to the zero signal at the direct output of the fourth RS flip-flop 22. When the front crutch 27 reaches the vertical position at the output of the vertical sensor 14, a single signal that is fed to the second input of the second logical element And 18. As a result, at the output of the second logical element And 18, a single signal is generated that translates the fourth R S-trigger 22 in a single state. A single signal from the direct output of the fourth RS-trigger through the third 17 and fourth 21 power amplifiers is supplied, respectively, to the input of the second solenoid 13 and the second input of the first polarity switch 12. As a result, the second solenoid 13 is triggered and the rear crutch is freed from fixing. At the same time, through the first polarity switch 12, the power signal is fed to the input of the first reversible motor 16, which, through the first gearbox 20, forces the rear crutch 24 to rotate also clockwise when looking in the direction of the vehicle. Thus, in the considered mode, both the front crutch 27 and the rear crutch 24 rotate clockwise when viewed along the direction of the vehicle with the same angular velocity in a mutually perpendicular position. When the crutch passes through an upright position, it, and therefore the corresponding part of the car, undergoes an elementary shift to the right (Fig. 2). Each such displacement leads to a corresponding elementary rotation of the car. And since there is an alternation of elementary displacements of the front and rear parts of the car, there is a gradual shift to the right of the entire car (Fig. 3). This movement of the car to the right continues until the driver generates a “stop” command in the form of a single signal at the second output of the command sensor 1, which is fed to the first inputs of the first 3 and third 26 logic gates And is maintained until the actual termination of the operation of both the first 16 and second 19 reverse engines . The first reversible engine 16 stops its operation when the front crutch 27 takes a horizontal position. Then, at the output of the first horizontal sensor 4, a single signal occurs, which is fed to the second input of the first logical element And 3, thereby causing the appearance of a single signal at its output, resetting the first 6 and third 11 RS-triggers to zero. A zero signal at the (direct) output of the first RS-flip-flop 6 through the first power amplifier 7 causes the first solenoid 8 to turn off and, through the second power amplifier 10 and the second polarity switch 15, removes the power signal from the second reversing motor 19, as well as through the second logical element And 18 causes the blocking of the arrival of single signals at the S input of the fourth RS-trigger. As a result, the second reversible engine 19 stops its operation and the front crutch 27 is fixed in a horizontal position, but the first reversible engine 16 continues to operate. When the rear crutch 24 reaches a horizontal position, a single signal arises at the output of the second horizontal sensor 25, which through the third logical element And 26 causes zeroing of the fourth RS-flip-flop 22. The zero signal at the output of the fourth RS-flip-flop 22 through the third power amplifier 17 causes the second solenoid 13 to turn off the fourth power amplifier 21 and the first polarity switch 12 remove the power signal from the first reversible motor 16. As a result, the rear crutch 24 is also fixed, and the first reversible motor 16 stops its operation. Thus, the lateral movement of the car to the right stops.

If necessary, make a lateral movement of the car to the left, for example for parking, the driver generates a code 1000 at the first output of command sensor 1, which enters the input bus of logic element 2 and the input bus of encoder 5. As a result, a single signal is generated at the output of logic element 2, which translates the first RS-trigger 6 in a single state. At the same time, single signals are generated at the first and second outputs of the encoder 5, which translate into a single state, respectively, the second 9 and third 11 RS-flip-flops. Further, the device works the same way as when executing a lateral movement command to the right, with the difference that now the first (control) inputs of the second 15 and first 12 polarity switches receive single signals that lead to the rotation of the front 27 and rear 24 crutches counterclockwise when viewed from the movement of the car. Moreover, the rear crutch 24 rotates 90 degrees behind the front crutch 27. When the car stops moving to the left, the front crutch 27 first stops and fixes in a horizontal position, and after a while the same thing happens with the rear crutch 24.

If necessary, make the vehicle turn clockwise in place, the driver generates code 0100 at the first output of command sensor 1, which enters the input bus of logic element 2 and the input bus of encoder 5. As a result, a single signal is generated at the output of logic element 2, which translates the first RS- trigger 6 to a single state. At the same time, at the first and second outputs of the encoder 5, a single and zero signals are formed, respectively, which transfer the second RS-trigger 9 to a single state and leave the third 11 RS-trigger in the zero state. Under such conditions of these triggers, as shown above, the front crutch 27 rotates clockwise, and the rear crutch 24 with the same angular velocity and with an initial angular delay of 90 degrees rotates counterclockwise when looking in the direction of travel of the car. Thus, the car is rotated in place clockwise at any desired angle. To complete the turn of the car, the driver generates a single signal at the second output of the command sensor 1 and maintains it until the second reversible engine 19 is completely stopped and the front crutch 27 is fixed in a horizontal position, and then those actions are performed with the first reversible engine 16 and the rear crutch 24.

If necessary, make the car turn in place counterclockwise, the driver generates code 0010 at the first output of command sensor 1, which goes to the input bus of logic element 2 and the input bus of encoder 5. As a result, a single signal is generated at the output of logic element 2, which translates the first RS- trigger 6 to a single state. At the same time, at the first and second outputs of the encoder 5, zero and single signals are formed, respectively, which leave the second RS-trigger 9 in the zero state and transfer the third 11 RS-trigger to the single state. Under such conditions of these triggers, as shown above, the front crutch 27 rotates counterclockwise, and the rear crutch 24 with the same angular velocity and with an initial angular delay of 90 degrees rotates clockwise when looking in the direction of travel of the car. Thus, the vehicle is rotated in place counterclockwise at any desired angle. To complete the turn of the car, the driver generates a single signal at the second output of the command sensor 1 and maintains it until the second reversible engine 19 is completely stopped and the front crutch 27 is fixed in a horizontal position, and then those actions are performed with the first reversible engine 16 and the rear crutch 24.

Power supply to the device, including the first 16 and second 19 reverse engines, can be provided due to the onboard power supply. As the vertical sensor 14, as well as the first 4 and second 25 horizontal sensors, you can use, for example, Hall sensors [1] with built-in permanent magnets with magnetic flux closure with crutches when they pass by the sensors.

Unlike the prototype, in the claimed invention, the car does not rise completely above the road surface during lateral movement, but all the time relies on the front or rear pairs of car wheels, as well as on one of the two crutches. A specific cross rolling of the car occurs. This allows you to drastically reduce energy costs for the transverse movement of the car, use less powerful and fewer energy motors and mechanical gears, thereby reducing the additional weight load on the car, at any time during the transverse movement the stability of the car is ensured.

Additional positive effects of the invention are the saving of time and fuel of the car when searching for parking spaces and, as a result, less air pollution from car exhausts.
