The above described prior art is configured to provide a balance detecting unit capable of detecting a load of a vehicle between a vehicle body and a damper so as to maintain the balance of the vehicle body by adjusting damping force according to the biased state of the detected load. However, the prior art still has problems that such configuration is limited to passenger cars only and determines the riding comfort of passengers and the abnormality of the vehicle by maintaining self-balance. Therefore, the prior art cannot be applied to a vehicle equipped with a loading box, which is used as a ground transportation apparatus such as a truck.
Accordingly, the present invention has been made in an effort to solve the above-mentioned problems occurring in the prior arts, and it is an objective of the present invention to provide a balance maintaining device for a transport apparatus, which can be provided to the lower portion of a vehicle that is a ground transport apparatus or a ship or a vessel that is a maritime transport apparatus so as to maintain the loaded cargo thereof in balance on an uneven ground surface or rough sea, thereby ensuring safety such that the ship is not tilted to sink, while converting the mechanical energy generated by the vibration of the ship into electric energy so as to separately use the electric energy. It is another objective of the present invention to provide a transport apparatus provided with said balance maintaining device.
As a technical concept for achieving the above objective, the present invention provides technical features of a balance maintaining device for a transport apparatus, including: a loading frame formed to be long in the lengthwise direction thereof and having two or more first and second supports, which are respectively formed at both sides of the lower portion of the loading frame; and a lower frame provided at the lower portion of the loading frame and having both upper side portions thereof linked and coupled to the first and second supports, the outside of the lower frame being coupled to a transport apparatus to maintain the loading frame in a horizontal state when the transport apparatus is shaken, wherein first and second support grooves are respectively formed at one side of the lower portion of each of the first and second supports of the loading frame, and two or more first and second coupling parts are respectively formed at both sides of the upper portion of the lower frame and have first and second connection grooves, which correspond to the first and second support grooves and are respectively formed at one side of each of the two or more first and second coupling parts so as to be spaced from each other at a predetermined interval, such that the first support groove and the first connection groove are respectively linked and coupled to each other by a coupling member and the second support groove and the second connection groove are respectively linked and coupled to each other by a coupling member.

According to the present invention, there are provided a balance maintaining device for a transport apparatus and a transport apparatus provided with said balance maintaining device, in which, when a transport apparatus 10 loads cargo and moves on an uneven ground surface or sea, passengers as well as cargo loaded in a loading frame 100 can be kept in balance without shaking to prevent the cargo from escaping, the gravity point of the loaded cargo is moved to a lower portion of the transport apparatus so as to ensure safe operation, and the power of the ship is generated by the vibration of the ship due to the influence of waves.
Now, preferred configurations and operations of the present invention for achieving the above objectives will be described with respect to the accompanying drawings by referring to
First, before describing the present invention, explaining the configuration as shown in
That is, the force of the loading frame 100 is transmitted to a lower portion by the weight of the cargo loaded on the upper portion of the loading frame 100 such that only the lower frame 200 moves while the loading frame 100 is maintained in a horizontal state, thereby preventing the escape of the cargo loaded in a loading box and ensuring safety.
The loading frame 100 is formed to load various cargoes thereon and may have four surfaces protruded upwards so as to prevent the loaded cargo from escape through the side portions of the loading frame 100, wherein the loading frame 100 is shown to be formed long in the lengthwise direction.
The lower frame 200 has an upper portion formed with first and second coupling part 210, 220 to be linked and coupled respectively to the first and second supports 110 and 120 of the loading frame 100, such that the lower frame 200 maintains the loading frame 100, which is provided above the lower frame 200 and linked and coupled to the lower frame 200, in a horizontal state and prevents the escape of the cargo loaded on top of the loading frame 100, by pushing the loading frame 100 downwards by the weight of the cargo.
Explaining the balance maintaining device for a transport apparatus according to the present invention as configured above in more detail, as shown in
That is, as shown in
Meanwhile, as shown in
The balance maintaining device for a transport apparatus according to the present invention as described above can be applied to and used in various transport apparatuses.
First, in the case of a ship used as a maritime transport apparatus 10, as shown in
In this case, even though the hull is moved due to external factors such as waves at the sea and thus the lower frame 200 coupled to the hull is also moved, the loading frame 100 can be maintained in a horizontal state by the cargo loaded thereon such that the hull can be prevented from being inclined to one side due to the cargo and thus prevented from sinking, thereby ensuring safety at sea.
Conventionally, a balance maintaining device including buoyancy members at both sides of the hull of a ship has been used in order to maintain the equilibrium of the ship. However, when the whole ship moves due to external factors such as waves, a leaning phenomenon of the ship may be generated since the cargo loaded in the ship moves in one side direction, causing the problem that the ship is completely inclined in one side direction due to the weight of the cargo and thus sunk in the sea.
In recent years, ships, which have been operated at sea, are tilted in one side direction by the external factors such as high waves and sunk by the shifting phenomenon of the cargo, which has been loaded on the ground surface, resulting in a lot of casualties simultaneously with huge economic loss
However, if the ship is equipped with a balance maintaining device according to the present invention, only the hull is moved by the waves at the sea but the loading box, in which the cargo is loaded, can be maintained in a horizontal state, such that the hull can be prevented from leaning and sinking to one side due to such a cargo shifting phenomenon.
In addition to the loading box, the boarding space to be occupied by passengers can be configured in the same manner as the loading frame 100 to be loaded with cargo, so that the passengers and the cargo can always be kept in a horizontal state, thereby providing comfort.
Meanwhile, explaining the balance maintaining device for a transport apparatus according to the present invention in more detail, for example, with respect to vehicles used as ground transport apparatuses 10 in addition to ships, as shown in
Herein, various kinds of cargo are loaded on the loading box coupled to the upper portion of the transport apparatus 10, and a load due to the weight of the cargo is transferred to the loading frame 100 as it is such that, when the vehicle moves on an uneven ground surface during traveling, the loading box can be maintained in a horizontal even if the vehicle body is moved to the left or right.
In addition, the balance maintaining device for a transport apparatus according to the present invention will be explained, for example, with respect to a bicycle, which is a moving means and can carry a simple load. Although not shown, such a bicycle includes a bicycle main body frame, which is provided with a handle for a driver to hold by hand, a saddle for the driver to directly sit thereon, and a space part formed at the rear side of the saddle such that a person can sit thereon or a load can be placed thereon, wherein wheels are axially coupled at both sides of the lower portion of the bicycle main body frame.
If the balance maintaining device for a transport apparatus according to the present invention is applied to this bicycle, the loading frame 100 is formed to be additionally connected to the loading space of the bicycle, on which a load can be placed, and the lower frame 200 is connected to the bicycle main body frame.
In this case, when the driver moves on an uneven ground surface during the riding of the bicycle, only the lower frame 200 is moved to the right and left, and the weight of both the driver and the load can be kept in a horizontal state.
Meanwhile, it is also conceivable to vary the structure of the loading frame 100, the lower frame 200 and the coupling member 300 respectively linked to the loading frame 100 and the lower frame 200.
As shown in
That is, the protrusion parts 112, 122 are respectively formed to be protruded in one side direction from the first and second supports 110, 120 of the loading frame 100, the protrusion parts 212, 222 are formed to be protruded in one side direction from the first and second coupling parts 210, 220 of the lower frame 200, and the coupling member 300 is formed with the groove parts 320, into which the protrusion parts 112, 122, 212, 222 can be fitted, so that the coupling member 300 can be engaged with the protrusion parts 112, 122, 212, 222.
Meanwhile, the coupling member 300 is tightened by elements such as typical nuts so as not to be detached from the protrusion parts 112, 122, 212, 222, thereby avoiding the escape thereof. In addition, when the protrusion parts 112, 122, 212, 222 are formed in plural numbers, it is preferable that the number of the coupling member 300 is also adjusted according to the number of the protrusion parts 112, 122, 212, 222.
