DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to a conventional vehicle, which is provided with a lift-up / down, traverse, and turning function in addition to the conventional functions of an automobile.
The present invention relates to a post-installable auxiliary mechanism.

[0002]

2. Description of the Related Art There is no prior art relating to the present invention. If we dare use similar technologies, we will add a thin deck-like traversing parking system that loads a car and runs on the floor, and a special mechanism that changes the wheels of the car from a normal state to a right angle. There were things that could turn around the body or move sideways. The former is a device that only moves horizontally in the left and right directions, but it is a major concern, and is expensive and hardly practically used. The latter has the function of turning and traversing, but it cannot be assembled and used later in a normal car, the mechanism is not compact, and the design and design of the whole car change drastically. It is difficult to retrofit, is complicated and expensive, lacks publicity, and has not been put to practical use.

[0003]

Most of the objects of moving a car beside it are to enable parking in a space where there is no room before and after the traveling direction. Therefore, driving a car is not expensive and exaggerated. It is desirable to have a horizontal movement function that can be operated from the seat. Since the traversing function often requires the accuracy of the direction determination, a direction correcting function is required. The use of this function is of little significance if it is a special device. Since the effect of use in a narrow parking lot becomes great only when a large number of vehicles are used, it is necessary to provide a mechanism that can be pre-installed and post-installed freely. In the prior art, it did not depend on such a mechanism. The problem to be solved by the invention of the present application is to provide a function assisting mechanism for an automobile, which can be pre-installed and post-installed with a mechanism having a function that can always be moved right beside by operation from a driver's seat.

[0004]

In order to solve the above-mentioned problem, as shown in the drawing, a grounded wheel is
The bending and stretching mechanism configured for each of the four wheels
Constructs a function to prevent the wheels from hanging, forms a roller that can be driven at the tip of its bending and stretching mechanism that lifts the car body and wheels from the ground at the same time, four wheels in the same direction,
In addition, a function of moving the vehicle right and left and right and left by the reverse rotation drive, and a turning function by the reverse rotation drive of the front two wheels and the rear two wheels which can accurately select the traverse are additionally provided. Further, the operation of this mechanism can be commanded by operating the operation panel switch of the electric nest fish mechanism installed near the driver's seat.
In addition, this function auxiliary mechanism has a structure that can be installed from the first new car or retrofitted to an existing car. In addition, the problem of the initials was solved so that it could be applied to all vehicles, and the lift-up / down function of both wheels made it easy to change tires, install and remove snow chains.

Further, after the fluid cylinder 2 is extended and the arm 2 swings and deploys, and the rollers are in contact with the ground, the vehicle body including the wheels is L-sized. It is a perspective view showing the state where it was lifted up only. FIG. 4 is a simplified plan view of a vehicle in which the vehicle body and the wheel suspension device are omitted, as viewed from above the vehicle on which the mechanism of the present invention is installed. FIG. 5 is a simplified diagram showing the state of the vehicle lifted up. It is a side view. FIG. 6 is a block diagram of a fluid cylinder drive control. FIG. 7 is a connection diagram inside the operation panel of the electric control mechanism. FIG. 8 is a view on arrow A in FIG. The basic structure of the present invention is composed of three mechanisms, one of which is a lift mechanism that is installed and mounted in the vicinity of each traveling wheel as described in claim 1, and is configured by expanding and contracting the fluid cylinder 1. A swing arm 1 having a dangling prevention function and fixing a wheel and a vehicle body; and an arm 2 which swings and expands and contracts by forming a roller at the tip by expansion and contraction of another fluid cylinder. The eye is claim 2
The operation of each cylinder is performed by oil or water of a non-compressed fluid, and the operation pressurization is performed by a pump powered by a car engine that is electrically turned on and off via an electromagnetic clutch, as described in It is an automatic control mechanism. The operation control of the plurality of fluid cylinders is as described in claim 3.

It is controlled by a relief valve, a solenoid valve or the like. The electric operation control is performed by a manual operation using a switch near the driver's seat on the operation panel of a third electric control mechanism arranged near the driver's seat, as described in claim 4. Has become. Therefore, although there is no characteristic new technology for each, the function auxiliary mechanism of the car that can lift up and down, drive right and left, run right and left, and set up fixed turning only by turning on and off the switch from the driver's seat in the car is , A new system. However, a mechanism that converts the expansion and contraction of the fluid cylinder 1 into swing of the arm 1 to prevent the wheels from hanging from the vehicle body, and swings another arm 2 connected to the arm 1 by the extension and contraction of the fluid cylinder 2 The structure of the double and telescopic system that lifts and lowers the entire vehicle body together with the wheels is compact, regardless of whether it is pre-installed or retrofitted.
There is a feature that it can be mounted and retracted on the underside of the vehicle body and a large lift amount can be configured. As described above, the invention of the present application makes it possible to control the vehicle delicately and finely, to make the parking operation easier than a skilled driver, and to greatly improve and facilitate tire replacement and snow chain attachment / detachment. The operation and effect of the present invention will be described with reference to the drawings. Figures 1, 2,
FIG. 3 is a perspective view showing an operation sequence of the lift mechanism of the present invention, and FIG. 1 shows a state in which the wheels of the vehicle are lifted down on a road surface or a floor surface and the vehicle is lifted down. The vehicle is in a normal running state where it can move forward and backward. In this state, when the vehicle travels, the lift mechanism (not shown) locks the fluid by the check valve. There is no such thing as it is firmly reduced to the underside of the body. Although the details at this time are not shown,
As described above, the fluid automatic control mechanism is in the lock stop state,
Therefore, although not shown, the operation panel of the electric control mechanism close to the driver's seat has the switch turned off unless it is confirmed by a sensor that the transmission is in a neutral state and the vehicle is not running when the engine is driven. It is in a state. If you stop running and want to change tires, put on or take off the snow chain, or move left or right and park in a narrow space, stop the car and keep the engine running. When the clutch of the Trussence mission is shifted to neutral, turning on the main switch of the operation panel of the electric control mechanism shown in FIG. 7 turns on the electromagnetic clutch shown in FIG. Although not shown in detail, the solenoid valves of the fluid automatic control mechanism were sequentially operated to sequentially operate the fluid cylinders, and the running wheels were prevented from hanging in the order of FIGS. In the state, L
Lifted up by dimensions. This state is shown in FIG. 5, and details thereof are also shown in FIG. However,
At this time, the primary switch of the operation panel of the electric control mechanism in FIG. 7 is in the neutral state of the stop command, and each roller is not driven. The car is in a stationary lift-up state, allowing tire changes and snow-chain removal work without jacking up. Difficulties in tire replacement and snow chain attachment / detachment work are associated with troublesome jack-up work for each wheel, which is dirty with oil and mud and takes time. The work can be lifted up and down on all four wheels at once by turning the switch on and off from the driver's seat in the car.
In particular, the attachment and detachment of the snow chain is troublesome, even for a skilled person, requiring more than 10 minutes per wheel. Regarding this snow chain, a one-touch detachable mechanism is separately filed for a patent, and if it is used in combination with the auxiliary mechanism of the present invention, the snow chain or ice-burn only on the road surface can be mounted and run. It is fast and easy to put on and take off each time, is not bothersome, can prevent damage to the road surface, tires and cars, and can run reliably on snowy and icy roads without slipping, enabling safe driving. Now, parking in a narrow parking space, such as parallel parking, which is almost the length and width of a car, is impossible with a normal car. The present invention has made that possible. If the car is stopped and lifted up in the parking space in an exactly parallel state, if all four rollers formed at the tip of the arm 2 are driven to rotate in the same direction, the four Depending on the direction of rotation of the rollers, if the parking space is on the right, the switch on the right side of the electric operation control board near the driver's seat, and if on the left, the switch on the left can be pressed. When the parking space is in a lift-up state that is not parallel to the parking space, the driving of the roller installed near the front wheel and the driving of the roller installed close to the rear wheel are set in opposition to normal and reverse rotation, and the parking space is set parallel to the parking space. Turn until it is. The right or left turn can be freely selected at the driver's seat by operating the switch. Next, regarding the working configuration,
This will be described in more detail. Now, assuming that the right front tire is punctured and you want to replace it. The tire must be lifted up as shown in FIGS. The lift-up operation of the vehicle function assisting mechanism of the present invention first stops the car completely in a flat and safe place, and the engine denoted by reference numeral 24 is in a state where the transmission is in a New Neutral state and is running. In this state, the driver's seat shown in FIGS. 4 and 5, the electric control console installed near the reference numeral 14, the main switch 15 and the reference numeral 15-1 in FIG. 7 are pushed in as shown by the arrow e1. 6, the clutch of FIG. 6, the reference numeral 18 is connected, and the rotational power of the rotating car engine, reference numeral 24 is transmitted to the fluid pump, reference numeral 17 via the transmission mechanism, reference numeral 19, and the tank, reference numeral From 20, pump the fluid,
By circulating in the directions of the arrows f1 and f4, the fluid automatic control mechanism, reference numeral 16 is operated. , Four sets of fluid cylinders 1 and 7 are simultaneously extended, the auxiliary arm 11 is swung by the arrow a1, and the arm 1 is swung by the arrow a2, the suspension rod of the wheel 5 A wheel hanging prevention mechanism, reference numeral 9 faces the lower side of the vehicle, and the wheels and the vehicle body are fixed. When the wheel and the vehicle body are fixed by the stroke sensor of the fluid cylinder, which is indicated by reference numeral 27, another solenoid valve of the fluid automatic control mechanism is actuated (not shown), and the pipe is moved to the arrow f3 from the pipe. The fluid is allowed to flow to extend the four sets of fluid cylinders 2, 6 from the distributor, 23,
The arm 2, which is equipped with a roller 12 which is driven by a motor 13 at the tip, and which is denoted by reference numeral 10, b1, b2
The vehicle and wheels are lifted up from the K-dimension shown in FIG. This sequence of operation should be understood from FIGS. The result is shown in FIG. 5, where the vehicle body, reference numeral 2 and wheels, reference numeral 3 are lifted up from the ground surface, reference numeral 1, by an L dimension. At this time, the switching switch 15-2 in FIG. 7 is always set to a neutral stop state. That is, the switching function of this switch does not work unless the main switch 15-1 is in the ON state.
When the motor 13 is not energized, the brake is applied when the motor is not energized, and the roller 12 does not rotate just by lifting up. Therefore,
Even if the lifted ground is slightly inclined, there is no danger of a natural escape. The motor denoted by reference numeral 13 can be constituted by either an electric drive or a fluid drive, and the first experimental mechanism uses a fluid motor. This lift
In the up state, the suspension spring denoted by reference numeral 4 does not change the condition for changing the dimension M1 in FIG. 2 and the dimension M2 in FIG. The wheels and the vehicle body 2 are fixed. The suspension rod with reference number 5 is d
The swinging motion of the arrow is when the lift-up in FIG. 1 is released, that is, when the vehicle is being lifted-down, and the vehicle is in a runnable state. The operation of the lift-up / down mechanism is complicated, but the actual operation is
A switch, symbol 15-1, is lifted up when turned on, lifted down when turned off, and is simple. This lift-up / down operation from inside the vehicle enables tire replacement and snow chain attachment / detachment for all four wheels, regardless of front or rear wheel fork or four-wheel drive. As shown in FIGS. 4 and 7, when the parking space is parallel to the car and the front and rear directions match the space, the left side is moved right and left in the direction of arrow B as shown in FIGS. If it is on the right side, it is moved right and left in the direction of arrow C. By operating the switch 15-3 shown in FIG. Switch, symbol 15-
2 is operated as indicated by an arrow e2 to switch on from the stop neutral to the left in the case of left alignment and to the right in the case of right alignment. It is rotated and moved to the left or right to the right, and the stop can be achieved by returning the switch 15-2 to the neutral position. The changeover switch 15-3 has no stop neutral function, but has a switch circuit in which the four wheels are in the same direction and the front and rear wheels are symmetrically reversed. Is turned on to the left,
When the changeover switch No. 3 is turned on from four wheels in the same direction to reverse rotation, which opposes the front and rear wheel positions of the vehicle, the vehicle turns right to the arrow D1. Turn left with the arrow. The turning is also stopped by setting the switch 15-2 to the neutral position for stopping. However, if a motor with a brake is used, the traversing and turning at the position of the stop command do not escape by inertia, Stop immediately. Therefore, when the car is lifted up, the turning operation for correcting the posture so as to be parallel to the parking space can be performed by the switch operation. The main switch 15-1 is operated so that there is no danger of lift-down during traversing or turning.
