Description

Boat seat suspension system {suspension system for boat seat}

The present invention relates to a boat seat suspension system, and more specifically, to a boat seat suspension system that reduces vibration and prevents shock.

In general, high-speed ships used for passenger ships, marine rescue, or illegal fishing crackdowns have hulls made of light yet strong glass fiber reinforced plastic or marine aluminum materials for rapid transportation. These high-speed ships have a control handle on the deck that allows the driver to control the direction of the ship, and a number of chairs are provided on the deck for seating multiple passengers in addition to the driver.

Here, the bow of the high-speed ship is raised and moves forward during propulsion as a thruster that generates propulsion by fuel is formed at the rear. At this time, the bottom of the high-speed ship collided with the waves and the shock applied to the ship was directly applied to the occupants, raising the risk of neck or back injury to the occupants. Moreover, the passenger sitting on the chair must exert strength throughout his or her entire body to prevent the passenger from falling off the chair due to shock. In this case, the passenger can easily become fatigued, and in severe cases, there is a risk of worsening injuries to the waist joint.

In addition, conventional ships' chairs were provided as fixed types with cushions applied to the frame, so that when a shock was applied to the hull from a high-speed ship, the shock was directly transmitted to the passengers through the chairs. Moreover, in the case of fixed chairs, they are not suitable for the body structure of each passenger, so they are made to assume an unstable posture, and the overall function of protecting the passengers is insufficient.

To solve this problem, a configuration using a buffer spring for shock relief has been disclosed in the past, but it has the limitation of providing only a limited buffering function within a set pressure or range.

In particular, when vibration corresponding to the resonance frequency of the shock absorber spring occurs, the vibration undergoes constructive interference and the amplitude of the vibration increases, so there is a problem in that the generated vibration and shock are directly transmitted to the passengers.

Since the function of the government 10e is the same as the above-described embodiment, detailed description will be omitted.

In addition, the seat portion includes a rail bogie portion 30, a seat connection frame portion 141, and a seat seat 40, and the seat connection frame portion 141 is located outside the bogie connection portion of each of the rail bogie portions 30. It is preferably provided to mediate the connection between each of the rail bogie units 30 and the seat sheets 40.

For example, the sheet connection frame portion 141 is provided in a flat form and disposed on the outside of each side frame of the fixed frame portion 10, and the rail guide portion 20 and the rail bogie portion are provided between each of the side frames. It is arranged to be spaced apart from (30) and may include a pair of first connection frames (141a) whose inner surfaces are coupled to the outside of the bogie connection portion.

In addition, the seat connection frame portion 141 is made of a square plate and may include a pair of second connection frames 141b that are opposed to each other at the rear of the seat 40. At this time, in this modification, the inner side of the second connection frame 141b in the width direction may be coupled to each of the first connection frames 141a.

Moreover, the sheet connection frame portion 141 is provided with a cross-section in the shape of a right triangle so that one side is coupled to the outer surface of each of the first connection frames 141a and the other side is coupled to the rear surface of each of the second connection frames 141b. It may further include a plurality of auxiliary connection frames 141f arranged to be spaced apart from each other in the vertical direction. Accordingly, the support strength of the sheet connection frame portion 141 can be increased.

In addition, the seat connection frame portion 141 may include a seat support frame 141c whose rear portion is coupled to the front of the second connection frame 141b and whose lower portion extends forward to support the seat 40. You can. At this time, the sheet support frames 141c may be provided as a set, spaced apart from each other in the width direction on both sides of the front of the second connection frame 141b, and the rear portions may be coupled to each other.

Moreover, the seat connection frame portion 141 is made of a rectangular plate, and the lower surface is seated and coupled to the upper front part of the seat support frame 141c, and the lower surface of the seat 40 is coupled to the upper surface. Can contain frames.

Meanwhile, an upper ring (52a) is formed on the upper part of the hydraulic damper part of the suspension part (50), and the upper ring (52a) is coupled to the upper shock absorbing part (141e) provided in the sheet connection frame part (141). It is desirable to be

Here, in this modified example, the upper shock absorbing part 141e extends in the form of a bar, so that one end is coupled to the upper ring 52a and the other end is connected to the first connection frame 141a of the sheet connection frame part 141. It can be combined within. In addition, the upper ring 52a is coupled to the upper buffer fixing part 141e, so that the suspension part 50 can be coupled to the sheet connection frame part 141.

Moreover, referring to Figures 1 and 2, in the boat seat suspension system 300 according to another modified example of an embodiment of the present invention, the vertical extension length of the fixed frame portion 10A is the same as that of the fixed frame of the above-described embodiment. It may be formed to be longer than the vertical extension length of the portion (10 in FIG. 3).

In this way, in the present invention, the suspension part 50, which provides a buffering force to the seat part, is placed inside the fixed frame (10, 10A, 110), thereby reducing the volume of the product, thereby improving space utilization within the hull and having a porous structure. The energy efficiency of the hull can be improved by reducing the weight of the fixed frames (10, 10A, 110).

In addition, the inner contour of the slide guide part 21 of the rail guide part 20, which extends in a polygonal cross-sectional shape, is made of carbon with low surface friction so that the oilless bush of the rail bogie part 30 can minimize friction. Since it is provided as a material, a separate liquid lubricant is not required, which improves cleanliness, provides a smooth riding sensation when going up and down due to the shaking of the seat, and prevents noise caused by friction.

And, in one embodiment of the present invention, the lower ring (51a) of the lower part of the shock absorbing body portion (51) is coupled to the shaft connection on one side of the lower shock absorbing portion (10e) provided in a cylindrical shape on the fixed frame portion (10). Since the upper ring (52a) of the upper part of the hydraulic damper part (52) is coupled to the upper buffer fixing part (41e) provided in the seat connection frame part (41), the lower part of the suspension part (50) is attached to the fixing frame (10). In a fixed state, shock can be stably absorbed as the upper part is compressed/expanded in conjunction with the lifting and lowering of the seat part.

Furthermore, an inclined support part that branches out in a 'Y' shape and expands in a direction away from each other is connected to the support coupling part 22 that extends integrally from the slide guide part 21 and is coupled to the fixed frame parts 10, 10A, 110. (22a) is formed, which can provide a synergy effect that provides solid support while making the product lighter.

On the other hand, when the hydraulic damper part 52 is compressed into the buffer body part 51, heat generation due to internal fluid resistance protrudes integrally from the buffer body part 51 so that the heat dissipation area is increased, and a flow path 50a is provided inside. Since heat is conducted to the outside of the communicating hydraulic control unit 54 and the shock absorbing body unit 51 and dissipated into the atmosphere, heat dissipation efficiency is improved and instantaneous shock absorption ability can be significantly improved.

In addition, the drive unit 55 is gear-coupled with the hydraulic control rotary unit 54b connected to the hydraulic control means 54a so that the opening degree of the flow path 50a is variably adjusted by rotation, and the instantaneous acceleration measured by the sensor unit 60 The control unit 70 compares the absolute value of and the preset setting value range to automatically adjust the opening degree of the flow path in stages. Accordingly, the constructive interference between the resonance frequency caused by the hull rocking and the resonance frequency of the suspension 50 is controlled to be automatically removed, thereby significantly reducing vibration and shock, thereby providing a comfortable riding experience. In other words, the resonance frequency due to hull rocking and the resonance frequency of the suspension unit 50 can be offset by variable adjustment of the opening degree of the passage 50a, thereby preventing safety accidents due to rapid changes in the marine environment and significantly improving the safety of use. there is.
