The foldable three-body boat is convenient for transportation by planes, trains, automobiles and steamships.

Referring to fig. 1 to 4, the present invention provides a foldable trimaran 100, wherein the foldable trimaran 100 comprises a main body 110, two sheets 120, two folding mechanisms 130 and a driving mechanism. The two sheet bodies 120 are respectively arranged at two sides of the main body part 110; the two folding mechanisms 130 are respectively arranged corresponding to the two sheets 120, each folding mechanism 130 connects the main body 110 with a corresponding one of the sheets 120, the folding mechanism 130 has a folded state and an extended state, and when the folding mechanism 130 is in the folded state, the two sheets 120 are retracted onto the main body 110; when the folding mechanism 130 is in the extended state, the two sheets 120 are unfolded to both sides of the main body 110. The driving mechanism is used for driving the folding mechanism 130 to switch between the folded state and the extended state.

In the embodiment of the present invention, the sheet 120 is connected to the main body 110 through a folding mechanism 130, and the folding mechanism 130 is driven to fold or extend, so that the folding mechanism 130 is switched between a folded state and an extended state, thereby realizing the conversion of the foldable trimaran 100 between a trimaran and a single body. For example, in a high sea state, the two side sheets 120 are unfolded to the two sides of the main body 110, so that the stability of the foldable trimaran 100 is improved, the viability is improved, and the requirement of the underwater detection equipment on working is met; meanwhile, under a low sea condition, the two side sheets 120 can be retracted to the main body 110 to be converted into a single boat, so that the contact area between the foldable trimaran 100 and water is reduced, the wave resistance of the foldable trimaran 100 is reduced, the foldable trimaran 100 can sail at high speed, and the maneuverability is improved.

There are various structures related to the folding mechanism 130, for example, the folding mechanism 130 is a multi-link structure, a flexible structure, a corrugated structure, etc., and is not limited in particular, and the folding mechanism 130 can be folded and unfolded, and can be designed according to actual needs. In addition, in order to enable the folding mechanism 130 to be rapidly switched between the folded state and the extended state, and to achieve rapid switching of the sheet 120, in the embodiment of the present invention, the folding mechanism 130 is driven by a driving mechanism to fold or extend. There may be various kinds of the driving mechanism, and for example, the driving mechanism may include a driving motor, a driving cylinder, a driving oil cylinder, or the like. And is not particularly limited herein.

The foldable trimaran 100 of the invention comprises a main body part 110, two sheet bodies 120, two folding mechanisms 130 and a driving mechanism, wherein the two sheet bodies 120 are respectively arranged at two sides of the main body part 110; each folding mechanism 130 connects the main body 110 with a corresponding one of the blades 120, the folding mechanism 130 having a folded state and an extended state, and when the folding mechanism 130 is in the folded state, the two blades 120 are retracted onto the main body 110; when the folding mechanism 130 is in the extended state, the two sheets 120 are unfolded to two sides of the main body 110; the driving mechanism is used for driving the folding mechanism 130 to switch between the folded state and the extended state. Thus, the foldable trimaran 100 of the present invention can be changed between trimaran and mono-hull according to sea conditions to adapt to different sea conditions; for example, in a high sea state, the two side sheets 120 are unfolded to the two sides of the main body 110, so that the stability of the foldable trimaran 100 is improved, the viability is improved, and the requirement of the underwater detection equipment on working is met; meanwhile, under a low sea condition, the two side sheets 120 can be retracted to the main body 110 to be converted into a single boat, so that the contact area between the foldable trimaran 100 and water is reduced, the wave-making resistance of the foldable trimaran 100 is reduced, the foldable trimaran 100 can sail at high speed, and the comprehensive strain capacity is improved.

Referring to fig. 1 to 4, in an embodiment, the folding mechanism 130 includes a first link 131 and a second link 132, one end of the first link 131 is hinged to the sheet 120, the other end of the first link 131 is hinged to one end of the second link 132, and the other end of the second link 132 is hinged to the main body 110. In this way, the folding mechanism 130 is switched between the folded state and the extended state by the first link 131 being hinged to the sheet 120, the first link 131 being hinged to the second link 132, and the second link 132 being hinged to the main body 110. It should be noted that the blade 120 and the main body 110 are fixedly connected through the first connecting rod 131 and the second connecting rod 132, so that the connection between the blade 120 and the main body 110 is more stable and has sufficient strength and rigidity.

Referring to fig. 1, in this embodiment, when the folding mechanism 130 is in a folded state, the first link 131 and the second link 132 are disposed in an overlapping manner. That is, when the folding mechanism 130 is in the folded state, the first link 131 coincides with the second link 132, so that the sheet 120 can be completely retracted onto the main body 110, the sheet 120 can be effectively prevented from contacting water, and the wave resistance of the foldable trimaran 100 is greatly reduced.

Referring to fig. 3, in this embodiment, when the folding mechanism 130 is in the extended state, the second link 132 abuts against the main body 110, and the first link 131 extends out of the main body 110. That is, when the folding mechanism 130 is in the extended state, the second connecting rod 132 rotates to abut against the main body 110, so that the contact area between the second connecting rod 132 and the main body 110 is increased, which is beneficial to improving the supporting effect of the main body 110 on the second connecting rod 132, further increasing the pulling force of the second connecting rod 132 on the first connecting rod 131 and the sheet body 120, and being beneficial to improving the connection stability between the sheet body 120 and the main body 110.

Alternatively, referring to fig. 1, 2 and 3, the length of the first link 131 is smaller than the length of the second link 132. Considering that the first link 131 extends out of the body 110 when the folding mechanism 130 is in the extended state, the length of the first link 131 may be made smaller than the length of the second link 132 in order to secure the stability of the foldable trimaran 100 on the one hand and to reduce the overall width of the foldable trimaran 100 and improve the maneuverability of the foldable trimaran 100 on the other hand. Of course, it is understood that in other embodiments, the length of the first link 131 may be equal to the length of the second link 132, and is not limited herein.

With the three hydraulic swing cylinders 160, the deployment of the blade 120 to both sides of the main body 110 can be rapidly and precisely controlled.

Specifically, a first through hole corresponding to the first lock slot is formed in the first connecting rod 131, and a second through hole corresponding to the first through hole is formed in the second connecting rod 132, so that when the folding mechanism 130 is in the extended state, the first push rod 142 can push the first locking pin to pass through the first through hole and the second through hole and be inserted into the first lock slot of the main body positioning seat 140. The first push rod seat 143 is used for providing limiting protection for the first push rod 142, and preventing the first push rod 142 from being affected by wave impact in the sailing process.
