[0001] The invention belongs to the technical field of underwater vehicle accessories, and in particular relates to a lighting device for a vehicle. Background Art

[0002] Underwater vehicles are the main tools for underwater exploration and are important means of transportation for people to explore and observe the underwater environment. Underwater vehicles need to be equipped with lighting devices to illuminate the underwater environment in order to facilitate visual collection of the underwater environment. When conducting underwater navigation exploration, water pressure and complex underwater environment will have an impact on the vehicle, mainly the lighting device. Damage to the lighting device will cause the underwater vehicle to lose its navigation function. Traditional underwater vehicles usually directly set a protective shell for the lamp body. As the water depth increases, the shell is larger in size and is under severe pressure, which will increase the chance of damage. In addition, during underwater collisions, the vibration of the shell will still be transmitted to the lamp body, causing damage to the lamp body. Summary of the invention

DETAILED DESCRIPTION

[0019] like Figures 1 to 3 As shown, the present invention discloses a lighting device for an aircraft, which is installed on the outside of an underwater aircraft and is used for lighting and pathfinding of the aircraft, such as Figure 1 and Figure 2 As shown, this lighting device includes a lamp body 1 and a protective shell 2, the lamp body 1 is suspended inside the protective shell 2, the protective shell 2 includes a cylindrical shell 21, the front end of the shell 21 is sealed with a layer of glass cover 22, the glass cover 22 is a convex spherical surface, the lamp body 1 is directed toward the glass cover 22, the rear end of the shell 21 is sealed and slidably provided with a piston 23, the outer layer of the piston 23 is made of rubber material, the inner side of the rear end of the shell 21 is respectively provided with a front stop ring 24 and a rear stop ring 25, the piston 23 is located between the front stop ring 24 and the rear stop ring 25, and a cylinder is formed between the front stop ring 24 and the rear stop ring 25 for the piston 23 to move.

[0020] This lighting device provides protection for the lamp body 1 by equipping the outer layer of the lamp body 1 with a protective shell 2. The protective shell 2 is provided with a glass cover 22 for the light source of the lamp body 1 to illuminate. By providing a movable piston 23, after the lighting device sinks into the water along with the underwater vehicle, the water pressure suppresses the piston 23, so that the internal space of the protective shell 2 is reduced, so as to narrow the gap between the internal pressure of the protective shell 2 and the external water pressure. The front baffle ring 24 and the rear baffle ring 25 limit the moving area of ​​the piston 23. The front baffle ring 24 separates the placement space for the lamp body 1, and the rear baffle ring 25 blocks the piston 23 to prevent the piston 23 from slipping out of the shell tube 21. This device protects the lamp body 1 by providing the protective shell 2 to avoid damage to the lamp body 1 during underwater navigation, and provides a variable pressure protective shell 2 to ensure that the protective shell 2 will not be damaged due to excessive water pressure when diving into a deep water area.

[0021] In a further solution, Figure 2 and Figure 4 As shown, a vertical rod 26 is fixedly arranged on the side of the shell 21, and the vertical rod 26 penetrates from the outside of the shell 21 into the inside of the shell 21, and the vertical rod 26 is sealed and fixedly connected to the side wall of the shell 21, and the vertical rod 26 is hollow, and the circuit of the lamp body 1 extends from the vertical rod 26 into and is connected to the lamp body 1 to provide energy to the lamp body 1, and the shell 21 is connected to the underwater vehicle through a connecting component, and the vertical rod 26 is also connected to the underwater vehicle, and the circuit extends to the underwater vehicle through the vertical rod 26. Figure 2The vertical rod 26 is provided with a ball head seat 261 at the end portion in the shell tube 21, and the surface of the ball head seat 261 is smooth. A concave ball groove 11 cooperating with the ball head seat 261 is provided on the side of the lamp body 1, and the ball head seat 261 is rotatably arranged in the concave ball groove 11. A support ring plate 12 is provided on the outside of the lamp body 1, and two outer ring plates 27 are provided on the inside of the shell tube 21. The two outer ring plates 27 are respectively located on both sides of the support ring plate 12. A plurality of springs 28 are supported between the outer ring plate 27 and the support ring plate 12, and six high-strength springs 28 are provided between each outer ring plate 27 and the support ring plate 12. The springs 28 are arranged in an array around the lamp body 1.

[0022] In this scheme, a vertical rod 26 is provided to provide circuit support for the lamp body 1, and the lamp body 1 is rotatably set at the end of the vertical rod 26 by means of a ball connection, an outer ring plate 27 is provided in the front and rear directions of the lamp body 1, a support ring plate 12 is provided in the middle of the lamp body 1, and the lamp body 1 is supported and suspended by a spring 28. Under this structure, the high-strength springs 28 provided on both sides of the support ring plate 12 can ensure that the lamp body 1 is located in the middle of the protective shell 2 when there is no collision through clamping support, thereby realizing the lighting function; when the lighting device is hit, the lamp body 1 is supported by the spring 28, and the lamp body 1 is adaptively rotated around the ball head seat 261, and overcomes the elastic force of the spring 28. The spring 28 can be freely compressed and swung slightly to ensure that the multi-directional impact force on the lamp body 1 is consumed. This device improves the safety of the lamp body 1 when sailing underwater by providing a multi-directional free-style elastic energy-consuming structure.

[0023] In a further solution, Figure 2 As shown, the middle of the rear baffle ring 25 is enclosed with an elastic membrane 3, and the elastic membrane 3 is a highly elastic, wear-resistant, weather-resistant, waterproof and breathable TPU film. Figure 2 Under the pressure of water pressure, the water pressure presses the elastic membrane 3 in the middle of the rear retaining ring 25 inward, and the elastic membrane 3 gradually deforms inward and presses against the surface of the piston 23, and then the water pressure presses the piston 23 inward, so that the piston 23 moves and compresses the internal space of the protective shell; the elastic membrane 3 is deformed with the water pressure, and the elastic membrane 3 is at the outer end of the shell cylinder 21 and is blocked by the piston 23. The elastic membrane 3 plays the role of sealing the shell cylinder 21 to prevent water from entering the protective shell 2. It is worth noting that the elastic membrane 3 only serves as a waterproof structure to isolate water and air.

[0024] In a further solution, Figure 2 and Figure 3 As shown, a plurality of connecting columns 29 are threadedly connected to the outer ring plate 27 , and a traction head 291 is coaxially rotatably provided on the connecting column 29 , and the traction head 291 is coaxially connected to the spring 28 .

[0025] In this structure, by rotating the connecting column 29, the supporting length of the spring 28 between the outer ring plate 27 and the supporting ring plate 12 can be adjusted to adjust the supporting force of the spring 28. This is suitable for adjusting the setting position of the lamp body 1 in the protective shell 2 to fine-tune the illumination angle, and can timely adjust the lamp body 1 to return to its original position after the lamp body 1 is deflected after multiple vibrations.

[0026] In a further solution, Figure 2 As shown, the shell tube 21 includes a front tube 211, a middle tube 212 and a rear tube 213, and the front tube 211 and the rear tube 213 are respectively threadedly connected to the front and rear ends of the middle tube 212.

[0027] By dividing the shell 21 into three parts, it is convenient to adjust the front and rear end connecting columns 29 inside the centering tube 212, and it is also used for replacing the glass cover 22 and the piston 23, so that the lighting device can be partially replaced in time when it is partially damaged.

[0028] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
