Description

Vehicles that can rotate in place

The present invention relates to a vehicle capable of in-situ rotation (i.e., radius free rotation or minimum radius rotation). More particularly, the present invention relates to a vehicle capable of rotating in place in a narrow space without requiring a special turning radius.

In general, a vehicle requires a constant radius of rotation for rotation (broadly, turning). Since the center of the rotation radius is located at a distance from the vehicle, it becomes difficult for the vehicle to rotate in a space that is narrow enough to secure a sufficient rotation radius.

In particular, from the driver's point of view, these difficulties are frequently encountered when the vehicle is parked. Of course, the driver may park the vehicle in a confined space by repeating the process of forwarding / reversing the vehicle several times, but even in this case, the driver's effort, time and fuel may be consumed and the vehicle may be damaged. There may be a problem.

To help understand the turning radius of the vehicle, consider the following examples.

1 is a diagram showing a turning radius of a vehicle generally required.

As shown in FIG. 1, the vehicle 10 is rotated with a predetermined radius of rotation r. In this case, the center c of the turning radius r is at a position away from the vehicle 10 by a certain distance. Furthermore, considering the width and length of the vehicle 10, the actual turning radius required by the vehicle 10 will be larger than the turning radius r shown.

Therefore, the inventor (s) proposes a new technique to solve the above problems.

The present invention aims to solve all of the above-mentioned problems of the prior art.

It is another object of the present invention to provide a vehicle capable of rotating in place.

The present invention also aims to reduce the radius of rotation of the vehicle.

[Preferred Embodiments of the Invention]

Schematic configuration of the vehicle that can be rotated in place

As shown in FIG. 2, the vehicle 10 capable of rotating in place according to an embodiment of the present invention includes a plurality of driving sources 100, a plurality of rotating means 200, at least one in situ rotating device 300, It may be configured to include a battery unit 400 and the control unit 500.

First, each of the plurality of driving sources 100 according to an embodiment of the present invention has a function of driving the vehicle 10 by converting electrical energy from the battery unit 400, which will be described later, into mechanical rotational energy-that is, rotation. Function of driving the means 200. The drive source 100 may be a known electric motor. However, the present invention is not necessarily limited thereto.

Next, each of the plurality of rotating means 200 according to an embodiment of the present invention may be driven by a drive source 100 corresponding thereto to perform a function of driving the vehicle 10. The rotating means 200 may be one of a pair of front wheels and a pair of rear wheels that are common in most vehicles 10. In particular, each rotating means 200 can be driven independently from the other rotating means 200 paired with it. As will be described later, due to the mutually independent driving of the pair of rotation means 200, in-situ rotation of the vehicle 10 according to the present invention can be implemented.

Next, the at least one in-situ rotating device 300 according to an embodiment of the present invention may operate together with the pair of rotating means 200 to allow the vehicle 10 to rotate in place as described below.

The in-situ rotating device 300 according to the present invention will be described in more detail later.

Next, the battery unit 400 according to an embodiment of the present invention may include electrical storage means that can supply electrical energy to the driving source 100 and can be charged and discharged. In order to implement such a battery unit 400, conventionally known electrical storage means can be used without limitation, for example, lead-acid battery, nickel-cadmium (Ni-Cd) battery, nickel-hydrogen (Ni-MH) battery And secondary batteries such as lithium ion (Li-ion) cells, lithium ion polymer (Li-ion polymer) cells, and the like. In addition, the battery unit 400 may be composed of a plurality of divided batteries (not shown) instead of one. The plurality of divided batteries may be electrically connected to each other, but may also be independent of each other.

Finally, the control unit 500 according to an embodiment of the present invention may perform a function of controlling the driving source 100, the rotation means 200, the in-situ rotating device 300, and the battery unit 400. The controller 500 controls a control signal exchanged or flowing between the above components and other non-shown components (eg, a load) of the vehicle 10 so that each component performs its own function. can do.

In particular, the controller 500 according to an embodiment of the present invention controls the driving of the rotating means 200 and the in-situ rotating device 300 protruding from the vehicle 10 or being stored in the vehicle 10. In situ rotation according to the invention can be realized.

The composition of the rotating device in place

Hereinafter, the configuration of the in-situ rotating device 300 performing important functions for the implementation of the present invention and the function of each component will be described in detail.

As shown in Figure 3, the in-situ rotating device 300 according to an embodiment of the present invention may include a support 310 and the rotating unit 320.

The support 310 according to an embodiment of the present invention is a position of the transverse center of the vehicle 10 (or, such a center) as shown in FIG. 3 so that the vehicle 10 does not lose balance while the vehicle 10 is rotated in place. From a position substantially close to the). Of course, if two or more in-situ rotating devices 300 of the type shown in FIG. 3 are employed and used in combination, each support 310 may be arranged such that their center is in such a position.

At least a part of the in-situ rotating device 300 may be housed inside the vehicle 10 as shown in FIG. 3 (FIG. 3 is a part of the in-situ rotating device 300 for convenience of description. Although normally shown as protruding out of the vehicle 10, this configuration is less desirable. Obviously, the configuration that allows the whole of the in-situ rotating device 300 to be housed inside the vehicle 10 is generally known. When the vehicle 10 rotates in place, as shown in FIG. 4, the vehicle 10 may protrude out of the vehicle 10 to lift some of the rotating means 200 from the ground 20. On the other hand, in this case, the lifting means 200 to be lifted should be a rotating means 200 opposite to the rotating means 200 to work together with the in-situ rotating device 300 to rotate the vehicle 10. Accordingly, the support 310 of the in-situ rotating device 300 may protrude from the vehicle 10 or may be stored in the vehicle 10 to perform such an operation. As a component for protruding and receiving the support 310, for example, a mechanical actuator (not shown), an electric actuator (not shown), a mechanical electric actuator (not shown), a hydraulic actuator (not shown), Pneumatic actuators (not shown) and the like can be used.

The rotating part 320 according to an embodiment of the present invention may be connected to one end of the support part 310. The rotating part 320 may come into contact with the ground 20 when the support 310 is protruded to lift some of the rotating means 200 from the ground 20. The rotating unit 320 may perform a function of causing the vehicle 10 to rotate in place according to the driving of one of the pair of rotating means 200 which is not lifted while in contact with the ground 20. On the other hand, if necessary, the rotating unit 320 may also be stored (completely) in the vehicle 10, of course.

According to a preferred embodiment of the present invention, the rotating part 320 may be configured as a passive wheel. Such passive wheels do not require a separate drive source to allow it to be driven by itself. By employing such a configuration, the vehicle 10 according to the present invention can still require only a small turning radius while reducing the torsional load on the vehicle 10 even when rotating in place.

Further, the passive wheels constituting the rotating part 320 are more preferably smaller wheels than the individual rotating means 200. By adopting such a configuration, it is possible to avoid the phenomenon in which the rotating part 320 makes unnecessary ground contact motion during the in-place rotation of the vehicle 10.

Finally, it may be more preferable that the passive wheels constituting the rotating part 320 are eccentric wheels as shown. These eccentric wheels can easily rotate together in the direction in which the vehicle 10 rotates.

Control method for in situ rotation

Hereinafter, a control method for in-situ rotation of the vehicle 10 according to the present invention will be described with reference to FIG. 5. Here, the control method will be described taking the case where the vehicle 10 is parked as an example, but it is obvious that the control method can be applied to other types of in-situ rotation of the vehicle 10.

As shown in FIG. 5, when the vehicle 10 needs to be parked in a narrow space, the rear part of the vehicle 10 in which a pair of rotating means 200 (ie, a pair of rear wheels) is disposed takes precedence. It may be entered into the space. In this case, the in-situ rotating device 300 may be opposed to the pair of rotating means 200.

According to a predetermined operation of the driver, the controller 500 may first control the in-situ rotating device 300 to sufficiently protrude from the ground 20. As a result, the other pair of rotating means 200 (that is, the pair of front wheels) is raised to face the pair of rotating means 200 of the vehicle 10.

Then, the control unit 500 may control such that only the left rotating means 200 (that is, the left rear wheel) of the unlifted pair of rotating means 200 of the vehicle 10 is driven forward. In this case, the right rotating means 200 (ie the right rear wheel) of the unlifted pair of rotating means 200 may be in a stopped state. Under this control, the front part of the vehicle 10 enters into the narrow parking space while rotating clockwise as shown.

Subsequently, according to the driver's operation, the control part 500 controls only the rotation means 200 (right rear wheel) of the right side of the pair of rotation means 200 which is not lifted of the vehicle 10 to drive forward, The vehicle 10 may be forced out of the parking space.

Of course, it will be apparent to those skilled in the art that the control method described herein may be applied to other types of vehicles (eg, 4WD vehicles or front wheel drive vehicles, etc.) rather than rear wheel drive vehicles.

Application of the present invention

Here, the application of the present invention, which has been briefly described above, will be described in more detail.

As shown in FIG. 6, the vehicle 10 may take a configuration including a pair of rotating devices 300 in front of a pair of rotating means 200 (ie, a pair of rear wheels) that are not lifted. Can be. Each configuration of this pair of rotary devices 300 may be substantially the same as the configuration of the in-situ rotary device 300 as described above. However, according to this application example, the pair of rotary devices 300 are spaced apart from each other at some interval, so that the vehicle 10 is stably even when the vehicle 10 rotates according to the principles of the present invention. Can achieve the effect of moving.

Although the present invention has been described by specific matters such as specific components and limited embodiments and drawings, it is provided only to help a more general understanding of the present invention, and the present invention is not limited to the above embodiments. Those skilled in the art may make various modifications and changes from this description.
