Description

Car lifting device {Apparatus for lifting car}

The present invention relates to a car lifting device, and more particularly, to a car lifting device that can partially lift the car to effectively park more cars in a predetermined space.

In recent years, the use of automobiles has increased as the economy has been activated and living standards have improved. As a result, cars are no longer a luxury item, but a necessity for life.

However, as the use of automobiles becomes active, parking problems of automobiles are emerging. In other words, in Korea, the parking problem of cars overflowing compared to the private area of the land is a serious situation.

Accordingly, a technique for solving the parking problem of an efficient vehicle is disclosed in Korean Laid-Open Patent Publication No. 1998-048114. The disclosed design is briefly described with reference to FIGS. 7 to 9 as follows.

First, when the switch of the support means is turned on in order to lift the vehicle to a predetermined height while the vehicle parking distance is not sufficiently secured, the oil pump is operated and at the same time, the oil in the oil storage tank is transferred to the oil pipe ( 30 is supplied to each ram 19. The ram 19, which has been supplied with oil, is extended in stages by the oil pressure formed by the oil, and is in contact with the ground using the wheel 20 at the bottom.

If it extends further and has the maximum length, the whole vehicle including the wheels is lifted to a certain height. That is, the vehicle is in a state of being supported by four rams 19. The hydraulic pressure formed in the ram 19 at this time can be maintained for a necessary time by pressure holding means on the oil pipe 30, for example, a flow rate time sensor.

After selecting the rotational direction of the vehicle and turning on the drive means, the motor drive source 16 rotates, and the rotational force at this time is driven with the coupling 27, the electric shaft 18, the electric gear 17 and the drive. The drive shaft 15 is rotated while passing through the gear 14.

When the drive shaft 15 rotates in this way, the rotational force is transmitted through the gear portion 11a engaged with the gear portion 11b thereof, and the entire vehicle body including the housing 12 makes the drive shaft 15 the rotation center axis. It rotates in the same direction as the rotation direction of this 15.

At this time, the stop pin 23 which rotates together with the drive shaft 15 is rotated along the pin guide groove 24 of the housing 12 and is blocked by a blocking wall in the groove blocking the progress of the stop pin 23. At the same time, the rotation of the drive shaft 15 can be limited in this position.

That is, the drive shaft 15 is rotatable only within the 90 ° range from the initial position to the position where the stop pin 23 is blocked. This means that the front part of the vehicle can be switched to a 90 ° rotated state from the initial state, the motor drive source 16 is connected in connection with the operation of the stop pin 23 or the drive shaft 15 in this state is completed At the same time, the oil supplied to the ram 19 is recovered and the length of the ram 19 is reduced to its original size, thereby allowing the vehicle to travel in the 90 ° converted direction. Therefore, the car can be parked effectively even in a narrow place.

By the way, in such a conventional vehicle lifting device (it is referred to as "vehicle attitude change device" in the original application), it may be easy to park the car in a narrow place such as an alley or a courtyard, but basically a predetermined space You can't park more cars inside.

Therefore, there will be a need for a means to effectively park more cars in a given space. In addition, there is a need for a means of allowing the vehicle to be partially lifted at an angle to replace the flat tires or perform the undercarriage of the car, as well as parking issues.

Accordingly, it is an object of the present invention to provide a vehicle lifting device that can partially lift a car so that more cars can be parked effectively within a predetermined space.

In addition, another object of the present invention is to provide a car lifting device that can partially lift a car at an angle to replace a flat tire or to perform a lower part of a car as well as a parking problem.

Here, the power transmission device has a rotational movement portion, a linear movement portion, the rotary movement portion and the joint portion for interconnecting the linear movement portion.

The rotary motion unit includes a drive motor that is turned on and off by a battery mounted to the vehicle, and a reducer that reduces the rotational driving force of the drive motor.

The linear movement portion is connected to the joint portion and the ball screw to rotate by the rotary movement portion, the ball screw is coupled to the outside of the ball screw is movable along the longitudinal direction of the ball screw by the rotation of the ball screw Its end portion includes a movable portion coupled to the link.

A rolling wheel is provided at the end of the lifter.

Hereinafter, with reference to the accompanying drawings will be described in detail for the subject innovation.

As shown in FIGS. 1 and 2A, the vehicle lifting apparatus according to the present invention is mounted on the device accommodating part 200 (see FIGS. 3 to 5) provided in the lower portion of the vehicle C. In general, the automobile C is divided into a front wheel (F / W) drive and a rear wheel (B / W) drive, and the spread of the automobile C, which is usually a front wheel (F / W) drive, is increasing. The automobile C of the front wheel F / W drive will be described as an embodiment.

When the lifting device 100 of the present invention is installed in the front wheel F / W driving car C, the device accommodating part 200 provided in the lower part of the car C adjacent to the front wheel F / W 200 (FIG. 3). To Fig. 5). Then, as illustrated in FIGS. 1 and 5, the front wheels F / W may be lifted upward by the rear wheels B / W while being supported by the ground E. FIG. Therefore, since the vehicle C-1 disposed behind the lifted space can be parked, more cars C and C-1 can be parked effectively in the predetermined space.

As shown in FIG. 2A, the vehicle lifting apparatus 100 according to the present invention is paired with the lower device accommodating portion 200 (see FIGS. 3 to 5) of the vehicle C adjacent to the front wheel F / W. (See FIG. 2B). This is to lift the vehicle C more stably. In some cases, if the size of the lifting device 100 is large, a single lifting device 100 may be employed.

Lifting device 100 is mounted to the lower portion of the vehicle (C) adjacent to the front wheel (F / W) is a power transmission device 110 for converting the rotational movement into a linear motion, and one end is in contact with the ground (E) A lifter 120 for lifting the vehicle C by moving with a predetermined inclination angle with respect to E), and a plurality of connecting links 130 for linking the power transmission device 110 and the lifter 120 to each other. do.

The power transmission device 110 has a rotary motion part 112, a linear motion part 114, and a joint part 116 interconnecting the rotary motion part 112 and the linear motion part 114 according to its position and role.

The rotary motion unit 112 includes a drive motor 112a that is turned on and off by the battery B mounted on the vehicle C, and a reducer 112b that reduces the rotational driving force of the drive motor 112a. Have At this time, the driving motor 112a may be controlled in its rotation speed and direction, and an on / off cycle by a control signal from a predetermined controller 140 (see FIG. 6).

Therefore, it may be employed as a stepping motor capable of controlling the stop angle of the drive motor 112a. In addition, since the battery B (refer to FIGS. 3 to 5) mounted on the vehicle C is a direct current power generating a force of about 12 volts [V], the driving motor 112a connected thereto also uses a direct current power supply. It would be advantageous to be employed with a working direct current motor.

The linear motion part 114 is connected to the joint part 116 and rotated by the rotary motion part 112, and the ball screw 114a is screwed to the outside of the ball screw 114a to rotate the ball screw 114a. It has the movable part 114b which can move along the longitudinal direction of the ball screw 114a.

Therefore, when the operation of the drive motor 112a is turned on by the predetermined controller 140, the driving force by the drive motor 112a is decelerated by the reducer 112b and then passes through the joint part 116. It is transmitted to the linear motion 114. Then, the ball screw 114a is rotated by the reducer 112b, and the movable part 114b screwed to the outside of the ball screw 114a is along the longitudinal direction of the ball screw 114a (see the arrow in FIG. 4). I can move it. At this time, since the lifter 120 is coupled to one end of the movable part 114b by the connection link 130, the lifter 120 may move in association with the movement of the movable part 114b.

The lifter 120 which is moved by the movement of the movable part 114b is integrally connected to the support section 120a and the support section 120a which form a substantially straight line according to the position thereof, and on the axis of the support section 120a. In comparison, it has an inclined section 120b formed to be inclined at a predetermined angle.

At the end of the support section 120a, a rolling wheel 122 rotatably supported by the ground E is mounted. The end of the inclined section 120b is coupled to the movable part 114b of the linear motion part 114 by the connection link 130.

Thus, as shown in FIG. 3, the control signal of the control unit 140 is transmitted to the driving motor 112a in a state in which the lifting device 100 is mounted on the lower portion of the vehicle C, so that When the operation is turned on, the driving force by the driving motor 112a is decelerated by the reducer 112b and then transmitted to the linear motion part 114 via the joint part 116.

Then, the ball screw 114a is rotated by the reducer 112b, and the movable part 114b screwed to the outside of the ball screw 114a is shown in FIG. 4, and the longitudinal direction of the ball screw 114a is shown. Can move in one direction. As such, when the movable part 114b moves in one direction, the lifter 120 coupled by the connection link 130 moves.

That is, the lifter 120 is subjected to the force of pressing the cloud wheel 122 side to the ground (E) with the axis of the point coupled to the movable portion 114b by the connecting link 130. Thus, as shown in FIG. 5, the rear wheel B / W side region of the automobile C can be lifted upward relative to the front wheel F / W.

After the rear wheel (B / W) area of the vehicle C is lifted, the car C-1 (see FIG. 1) parked behind is partially parked in the lower part of the lifted car C and is almost overlapped. As a result, parking spaces can be significantly reduced. In fact, the parking space required for one ordinary car (C) was about 5 m can be reduced to about 2.5 m to 3 m.

If you want to release the car (C) has been placed in the parking again for driving, by the control unit 140 so that the rotational direction of the drive motor (112a) is reversed. Then, the rear wheels B / W lifted around the front wheels F / W are lifted and the rear wheels B / W of the vehicle C may be in contact with the ground E again. Of course, if the lifting is to be lifted like this, the car C-1 that has been parked behind must be removed in advance.

As such, according to the vehicle lifting apparatus 100 of the present invention, more cars C can be effectively parked in a predetermined space.

In the above-described embodiment it has been described that the lifting device 100 can significantly reduce the parking space of the vehicle (C). However, the vehicle lifting device 100 of the present invention is not only usable when parking, but, for example, to replace the wheels of the flat car C or to carry out the lower work of the car C. It can also be used to lift partially.

In addition, in the above-described embodiment, the lifting of the automobile C by the vehicle lifting apparatus 100 has been described. However, the length varies depending on the type of automobile C. Therefore, as shown in FIG. 1, when the rear wheels B / W are lifted around the front wheels F / W, a predetermined cushioning means is further interposed in the bumper P mounted at the front of the vehicle C. It will be more effective to prevent the front lower area of the vehicle C from being damaged.

In the above embodiment, the lifting of the rear wheels B / W around the front wheels F / W has been described. On the contrary, of course, the front wheel F / W may be lifted around the rear wheel B / W.

In addition, two drive motors (not shown) may be provided so that each drive motor can be operated separately. In this case, the right region of the vehicle C is first lifted by the operation of the first driving motor, and then the left region of the vehicle C is lifted by the second driving motor, or the first and By simultaneous operation of the second drive motor, the vehicle C may be lifted at a time. Of course, this form of control can be modified in many ways.

As described above, according to the present invention, there is provided a vehicle lifting apparatus that can partially lift a vehicle so that more cars can be parked effectively within a predetermined space.

In addition, according to the vehicle lifting apparatus of the present invention, as well as parking problems, it is possible to partially lift the car at a certain angle in order to replace the flat tire or to perform the lower work of the car.
