Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1 to 3, the latch mechanism for a helicopter seatbelt provided in the present embodiment includes a housing 1, a hook 2, an elastic member 3, a metal buckle 4, a manual button 5, and an electromagnetic structure 6. The hook 2 is riveted inside the shell 1. Two ends of the elastic piece 3 are respectively connected to the hook 2 and the shell 1, and the elastic piece is used for keeping the hook 2 in a hooking state. The metal buckle 4 is in sliding fit with the shell 1, a through hole 41 for facilitating the hook 2 to hook the metal buckle 4 is formed in the metal buckle 4, and the upper end of the metal buckle 4 is connected with the safety belt 7. A manual button 5 is slidably disposed in the housing 1 for manually changing the status position of the hook 2. The electromagnetic structure 6 is arranged on the hook 2 and the shell 1 and used for automatically controlling and changing the state position of the hook 2. Wherein, the shell 1 adopts a metal structure and is a hollow cavity. The hook 2 is connected to the inside of the shell 1 through a rivet, so that the hook 2 can rotate, and the conversion of the position transition of the hook 2 is realized. One end of the elastic part 3 (a spring or a torsion spring, etc.) acts on the hook 2, and the other end acts on the inner wall of the shell 1, so that the hook 2 is in a hooking state (as shown in the position of fig. 1) under the action of the elastic part 3, and the purpose of fixing the safety belt 7 is achieved. The metal buckle 4 is a metal piece (made of stainless steel material) with a through hole 41 formed in the bottom, the top end of the metal buckle 4 is connected with the safety belt 7, and the metal buckle 4 is connected with the hook 2 in a matching mode through the through hole 41 in the bottom, so that the metal buckle 4 is matched with the shell 1 in a sliding mode, and the metal buckle 4 is hooked and clamped in the shell 1 under the action of the hook 2. The manual button 5 is in sliding fit in the shell 1, the bottom of the manual button 5 acts on the hook 2, when the manual button 5 moves downwards, the bottom of the manual button 5 pushes the hook 2 to rotate, so that the hook 2 moves to the position shown in fig. 2, the metal buckle 4 can be separated from the shell 1, and the effect of loosening and taking down the safety belt 7 is achieved. The electromagnetism structure 6 adopts magnetic force to overcome the elasticity of elastic component 3, make couple 2 rotatory to the position shown in figure 3 under the effect of magnetic force, thereby only need break-make alright with the position state of control couple 2 through control electromagnetism structure 6, can adopt electronic mode control to make safety belt 7 loosen, realize the purpose of swift convenient taking off safety belt 7, and when couple 2 is in the couple and gets the position (as shown in figure 1), owing to there is the effect of 6 magnetic forces of electromagnetism structure, make couple 2 have higher stability under this state, thereby improve safety belt 7's stability in use.

Further, the electromagnetic structure 6 comprises a permanent magnet 61, an electromagnet 62, and an electric button 63. The permanent magnet 61 is provided on the hook 2. The electromagnet 62 is arranged on the inner surface of the shell 1, when the hook 2 is in a hooking state, the permanent magnet 61 is tightly attached to the electromagnet 62, and when the electromagnet 62 is electrified, the magnetism of the adjacent surface of the electromagnet 62 and the permanent magnet 61 is the same. The electric button 63 is arranged on the outer surface of the shell 1 and electrically connected with the power supply of the electromagnet 62, and is used for automatically controlling and changing the state position of the hook 2. When the hook 2 is in the hooking state (i.e., the state that the occupant fastens the seat belt 7, as shown in fig. 1), since the permanent magnet 61 has magnetism, a certain magnetic attraction force exists between the permanent magnet 61 and the electromagnet 62, so that the hook 2 has a magnetic force effect in addition to the effect of the elastic member 3, and the hook 2 can be in the hooking state more firmly, thereby improving the use stability of the seat belt 7. When the electromagnet 62 is electrified, the electromagnet 62 generates magnetism the same as that of the permanent magnet 61 (adjacent surface), so that the permanent magnet 61 is subjected to repulsion force of the electromagnet 62 due to the fact that like magnetic poles repel each other, and the hook 2 overcomes the elastic force of the elastic part 3 and rotates under the action of the repulsion force, and the purpose of electrically loosening the safety belt 7 is achieved. Further, a safety cover may be provided around the power button 63, and the safety cover is fixed to the outer surface of the housing 1 by means of a hinge to prevent the safety belt 7 from being loosened by touching the power button 63 by mistake.

Furthermore, the hook 2 is Z-shaped, and a downward inclined slope is arranged at the contact part of the hook 2 and the metal buckle 4. By the slope at the position, when the safety belt 7 is fastened, the metal buckle 4 moves downwards, when the upper end of the hook 2 is contacted, due to the slope at the upper end of the hook 2, when the metal buckle 4 gives downward pressure to the top of the hook 2, the slope can disperse the downward pressure into a part of horizontal force to overcome the elastic force of the elastic part 3, so that the hook 2 is matched with the through hole 41 of the metal buckle 4, the purpose of fixing the safety belt 7 is achieved, and the force required when a passenger fastens the safety belt 7 can be reduced by arranging the slope, so that the safety belt 7 is fastened more conveniently.

In order to reduce the force required when the safety belt 7 is fastened, further, the bottom surface of the metal buckle 4 is provided with a downward inclined surface inclined towards the outside of the housing 1, and the inclined surface is similar to the above inclined surface function, so that when the metal buckle 4 gives pressure to the hook 2 downwards, more force can be applied to the horizontal direction (the force is decomposed according to the contact position of the metal buckle 4 and the hook 2, and the force in the horizontal direction is larger after the downward pressure is decomposed when the inclination of the contact surface of the metal buckle 4 and the hook 2 is larger), and therefore, only a smaller downward force needs to be applied to the metal buckle 4, the hook 2 can rotate under the action of the pressure, and the hook 2 is matched with the through hole 41 of the metal buckle 4.

Further, when the hook 2 is in a hooked state, the upper end of the manual button 5 is flush with the upper end of the housing 1 by the elastic force of the elastic member 3. When the passenger fastens the safety belt 7, the manual button 5 is positioned in the shell 1, and the situation that the safety belt 7 is loosened due to accidental triggering of the manual button 5 is avoided.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention. The present invention is not to be limited by the specific embodiments disclosed herein, and other embodiments that fall within the scope of the claims of the present application are intended to be within the scope of the present invention.
