JPS5851494B2 - Automobile with built-in jack - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile with a built-in jack, and more particularly to an automobile that uses exhaust gas from the automobile to mold the inside of the jack.

Conventionally, the jacks for automobiles such as passenger cars and trucks are portable, and these are always stored in the trunk, etc., and are used when changing tires, when a wheel falls off, when attaching tire chains, and when the suspension is stopped. Usually, when necessary, such as during inspection, it is taken out of the trunk and used with a jack.

Further, the jack is manually operated and has the disadvantage of being complicated to operate as described above, which is a source of trouble for female drivers or beginners in particular.

Furthermore, when using a jack, the driver etc. must step out of the vehicle to perform the work, which is a problem, especially on rainy days, and requires prior knowledge of the jack's installation location and operating method. there were.

SUMMARY OF THE INVENTION Therefore, in view of the above-mentioned problems, it is an object of the present invention to propose an automobile with a built-in jack in which the jacks can be pre-installed at necessary locations on the car and can be operated easily from inside the car. .

This invention will be explained below.

The present invention relates to an automobile with in-jacket molding, one pair near the left wheels 2 and 3 of the automobile, one pair near the right wheels 4 and 5, or one pair near the front wheels 2 and 4, and one pair near the rear wheels 3 and 5.
A total of two pairs of jack structures are fixedly attached to the lower part of the car body near the first jack structure, and each pair of jack structures is attached to the first
The electromagnetic valve and jack actuated pipe are connected to the exhaust pipe of the automobile via pressure regulating pulp, and
A second electromagnetic valve is connected to the engine inlet manifold by a disposed exhaust pressure pipe, the first electromagnetic valve is opened, the second electromagnetic valve is closed and the jack structure is placed in the operating mode, and the first electromagnetic valve is closed. The valve is closed and the second electromagnetic valve is opened to put the jack structure into an inoperative mode.

That is, as shown in FIGS. 1A and 1B, the left wheel 2 of the automobile 1
and 1 to 10A near 3, IOB, right wheels 4 and 5
A jacking structure of 1:10C, IOD is placed near the front wheels 2 and 4, or a jacking structure of 1:10B, 10D is placed near the front wheels 2 and 4, and a jacking structure of 1:10B, 10D is placed near the rear wheels 3 and 5 at the bottom of the car 1. As shown in FIG. 2, the cylinder 11 of the jack structure 10 is connected to the exhaust gas of the automobile by means of the electromagnetic valve 12 and the jack operating pipe 13. It is connected to the pipe 14 via a pressure regulating pulp 15 that can be opened and closed, and an electromagnetic valve 16 is connected to the engine inlet manifold 18 through an exhaust pressure pipe 17 disposed midway.

Further, below the cylinder 11 of the jack structure 10, a bellows 19 that can be expanded and contracted as well as a piston 20 connected to the lower end of the bellows 19 are arranged. A lock pin 21 for locking the vertical movement of 20 and a lock pin driving device 22 for driving this lock pin 21 are provided.

Since the jacking structures are formed in pairs as described above, one side of the automobile 1 can be lifted by driving each pair of jacking structures separately, and if necessary, by driving them simultaneously. It goes without saying that the entire car body can also be levitated.

In such a configuration, when it becomes necessary to use the built-in jack structure 10, the lock pin is activated via the lock pin drive device 22 by an internal (inside the vehicle) operation switch (not shown) while the engine is running. 21 is released, the pressure regulating pulp 15 is closed, the electromagnetic valve 12 is opened, and the electromagnetic valve 16 is closed.

As a result, the jack structure 10 enters the operating mode, and the piston 20 descends under its own weight, and exhaust gas from the exhaust pipe 14 enters the cylinder 11 through the jack operating pipe 13, so the bellows 19 expands due to the pressure of the exhaust gas. The piston 20 of the jack structure 10 descends as shown.

Thus, the jack structure 10 lifts one side of the vehicle 1, thereby making it possible to perform tasks such as replacing a tire.

In this case, the exhaust pressure is adjusted to a constant pressure (for example, 2.5 KiI/m2) by the pressure regulating pulp 15, so the automobile 1 does not fall due to its own weight, and the piston 20 is locked with the lock pin 21. This makes it possible to secure the vehicle body and ensure safety.

On the other hand, when the jack structure 10 is placed in the non-operating mode, the pressure regulating pulp 15 is opened using the above-mentioned operation switch, the electromagnetic valve 12 is closed, and the piston 20 is unlocked.

Therefore, when the electromagnetic valve 16 is opened, the cylinder 11
The exhaust gas inside is exhausted to the engine inlet manifold 18 through the exhaust pressure pipe 17, and the pressure inside the cylinder 11 decreases, causing the piston 20 to rise.

Thus, the automobile 1 descends and returns to its original normal position.

Then, at this return position, the piston 20 is moved to the lock pin 21.
Keep it locked.

As described above, according to the present invention, the built-in jack structure can be used by a simple operation from inside the vehicle, so even beginners who are not accustomed to jack operations can easily use it, and its utility value is extremely high.

Furthermore, since the pressure from automobile exhaust gas is used as the drive source for the jack, it is extremely economical.

Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.
