Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and particularly to a scale - type load - reducing device for a trans - medium vehicle. Background Art

[0002] When a trans - medium vehicle crosses a medium interface, such as entering water from the air, it needs to withstand huge impact loads. The impact load not only affects the mobility and entry speed during the water - entry process but also damages the structural integrity of the trans - medium vehicle and affects structural safety. Therefore, it is crucial to take load - reducing protection measures to reduce the impact on the vehicle during the medium transition. Researchers have carried out research on trans - medium load - reducing technologies, such as geometric shape optimization and reducing the water - entry speed. However, these load - reducing technologies have limited effects and are difficult to achieve good load - reducing effects at different water - entry speeds. They have obvious limitations and limited application scenarios. The development of trans - medium vehicles has put forward the demand for a load - reducing device that can effectively reduce loads in a wider range. Therefore, in view of the problem that traditional rigid load - reducing structures are difficult to adapt to complex impact loads during high - speed load reduction, the present invention proposes a load - reducing device for a trans - medium vehicle that can flexibly deform and provide better load - reducing performance at a wider range of water - entry speeds and water - entry angles. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem that traditional rigid load - reducing structures are difficult to adapt to complex impact loads during high - speed load reduction, and to propose a scale - type load - reducing device for a trans - medium vehicle.

[0004] To achieve the above - mentioned purpose, the present invention adopts the following technical solutions:

[0005] A scale - type load - reducing device for a trans - medium vehicle includes adjustable scales. The number of the adjustable scales is multiple, and the multiple adjustable scales are all installed on the lower surface of the bow of the trans - medium vehicle through a connection and rotation device.

[0006] The connection and rotation device includes two adjustment vanes, three connecting sleeves, two transmission shafts, two bevel gears, permanent magnets, ring connectors, multiple pairs of electromagnets, and a fixed base.

[0007] One of the adjustment vanes is fixedly connected to the surface of the trans - medium vehicle, and one of the vanes is fixed to two connecting sleeves. One of the transmission shafts is placed in the two connecting sleeves. The other adjustment vane is fixedly connected to one end of the adjustable scale, and the other vane is fixed to one of the transmission shafts through a connecting sleeve. One end of each of the two transmission shafts is fixedly connected to one of the two bevel gears, and the two bevel gears are meshed with each other.

[0008] Another one of the transmission shafts is rotatably mounted on the trans-medium vehicle through bearings. The other transmission shaft penetrates into the trans-medium vehicle and is fixedly connected to a permanent magnet. The permanent magnet is arranged on the ring-shaped connecting piece, and multiple pairs of the electromagnets are arranged on the surface of the ring-shaped connecting piece opposite to the permanent magnet.

[0009] Preferably, multiple pairs of the electromagnets are fixedly connected to a fixed base, and the fixed base is installed in the trans-medium vehicle.

[0010] Preferably, the number of each pair of the electromagnets is two, and the opposite two electromagnets have opposite polarities when energized.

[0011] Preferably, a solar panel is mounted on the surface of the adjusting scale.

[0012] Compared with the prior art, the present invention provides a scale-type load reduction device for a trans-medium vehicle, which has the following beneficial effects:

[0013] For the scale-type load reduction device of the trans-medium vehicle, when the trans-medium vehicle is sailing normally, the adjusting scales are in a retracted state at this time and are close to the surface of the trans-medium vehicle to reduce resistance. When the trans-medium vehicle enters the water, the connecting and rotating device drives the adjusting scales to open to an appropriate angle, and the adjusting scales directly bear the impact load, effectively reducing the impact of the water entry impact load of the trans-medium vehicle on the structural safety while ensuring various performance indicators and design requirements such as the motion stability of the trans-medium vehicle.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0023] Refer to Figures 1-6 , the scale-type load reduction device of the trans-medium vehicle includes adjusting scales 9. The number of adjusting scales 9 is multiple, and the multiple adjusting scales 9 are all installed on the lower surface of the bow of the trans-medium vehicle 10 through a connecting and rotating device;

[0024] The connecting and rotating device includes two adjusting vanes 1, three connecting sleeves 2, two transmission shafts 3, two bevel gears 4, a permanent magnet 5, a ring connector 6, multiple pairs of electromagnets 7 and a fixed base 8;

[0025] One of the adjusting vanes 1 is fixedly connected to the surface of the trans-medium vehicle 10, and one of the vanes is fixed to two connecting sleeves 2. One of the transmission shafts 3 is placed in the two connecting sleeves 2. The other adjusting vane 1 is fixedly connected to one end of the adjusting scale 9. A solar panel is installed on the surface of the adjusting scale 9. When the trans-medium vehicle 10 stays on the water surface, the trans-medium vehicle 10 can be inverted so that the adjusting scale 9 faces upward, and the solar panel installed on the adjusting scale 9 is relied on to supplement electric energy. At this time, the adjusting scale 9 can be adjusted in angle by the connecting and rotating device so that the solar panel is at the best angle, enhancing the endurance of the trans-medium vehicle 10. The other vane is fixed to one of the transmission shafts 3 through the connecting sleeve 2. One ends of the two transmission shafts 3 are respectively fixedly connected to the two bevel gears 4, and the two bevel gears 4 are meshed with each other;

[0026] Another transmission shaft 3 is rotatably installed on the trans-medium vehicle 10 through bearings. The other transmission shaft 3 penetrates into the trans-medium vehicle 10 and is fixedly connected to the permanent magnet 5. The permanent magnet 5 is arranged on the ring-shaped connecting piece 6. A plurality of pairs of electromagnets 7 are arranged on the surface of the ring-shaped connecting piece 6 opposite to the permanent magnet 5. When all the adjusting scales 9 on the surface of the head of the trans-medium vehicle 10 are rotated to a certain angle, the electrodes of the electromagnets 7 remain unchanged, the permanent magnet 5 is attracted and fixed, and the locking state is restored, so that each adjusting scale 9 can also be fixed after being stressed. The plurality of pairs of electromagnets 7 are fixedly connected to the fixed base 8, and the fixed base 8 is installed in the trans-medium vehicle 10. The number of each pair of electromagnets 7 is two, and the polarities of the two opposite electromagnets 7 are opposite when energized. By energizing the electromagnets 7 respectively, the electromagnets 7 respectively correspond to the two poles of the permanent magnet 5. Positioning and locking are achieved by the attraction between the opposite sexes of the permanent magnet 5 and a pair of energized electromagnets 7. And by energizing the electromagnets 7 in sequence, the permanent magnet 5 can be rotated by attracting the electrode. At this time, the adjusting scale 9 changes the angle under the drive of the bevel gear 4 and the transmission shaft 3, and reaches a new fixed position and is locked, so as to change the water-entry configuration of the head of the trans-medium vehicle 10, and then change the head configuration of the trans-medium vehicle 10 through the cooperation of multiple scales, so as to achieve an underwater head configuration with a lower impact load at different water-entry speeds and water-entry angles.

[0027] In this embodiment: when the trans-medium vehicle 10 is sailing normally, the adjusting scale 9 is in a retracted state at this time and clings to the surface of the trans-medium vehicle 10 to reduce resistance. When the trans-medium vehicle 10 enters the water, the connecting and rotating device drives the adjusting scale 9 to open to an appropriate angle, and the adjusting scale 9 directly bears the impact load, so as to effectively reduce the impact of the water-entry impact load of the trans-medium vehicle 10 on the structural safety while ensuring the various performance indicators and design requirements such as the movement stability of the trans-medium vehicle 10.

[0028] Working principle: During the normal sailing stage of the trans-medium vehicle 10, the permanent magnet 5 on the ring-shaped connecting piece 6 is attracted by adjusting the electrodes of the electromagnets 7, and the energized state is maintained to provide a locking force to keep the angle of the bevel gear 4, so that the adjusting scale 9 is fixed at an angle parallel to the surface of the head of the trans-medium vehicle 10;

[0029] When it is necessary to change the angle of the adjusting scale 9, the adjacent electromagnets 7 are energized in sequence, and their electrodes are changed in sequence. Based on the principle of attraction between opposite sexes and repulsion between the same sexes, the permanent magnet 5 is driven to rotate on the ring-shaped connecting piece 6, so that the transmission shaft 3 drives the bevel gear 4 to rotate. The two bevel gears 4 are meshed and driven, so that the other transmission shaft 3 drives the adjusting vane 1 to rotate, and the adjusting scale 9 adjusts the angle. When the permanent magnet 5 rotates to the corresponding position, the energized state of the corresponding electromagnet 7 remains unchanged. At this time, the position of the adjusting scale 9 is locked, so as to change the water-entry configuration of the head of the trans-medium vehicle 10 and reduce the impact load when entering the water.

[0030] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
