Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.

Referring to the attached drawings 1-8, the headset support device for the flight helmet comprises a circular fixing plate 2 used for being fixed with the side wall of the helmet 1 and a support device rotatably connected to the circular fixing plate 2, wherein the support device comprises a rotary fixing plate 3 and a support 4, a support mechanism is arranged in the rotary fixing plate 3 and used for opening and fixing or closing and fixing the support 4, and a rotating device used for mounting a headset 5 is arranged at the bottom end of the support 4. The overall installation principle is as follows: the circular fixing plate 2 is fixed on the side wall of the helmet 1, the rotary fixing plate 3 is fixed on the circular fixing plate 2 in a rotary manner and swings relative to the circular fixing plate 2 in the front-back direction of the helmet 1, the support 4 is mounted on the rotary fixing plate 3, the earphone 5 is rotatably mounted at the bottom end of the support 4 by a rotating device (the rotating device preferably comprises a mounting plate 41 fixed at the bottom end of the support 4, a rotating rod 42 is arranged on the mounting plate 41 facing the earphone 5, the rotating rod 42 penetrates into the side wall of the earphone 5, the whole earphone 5 can rotate on the rotating rod 42 in the circumferential direction, so that the earphone 5 can be opened outwards relative to the helmet 1), the support 4 can be opened and fixed or closed by applying external force through the action of a support mechanism, namely, the position state of the support 4 is kept fixed without the external force after the support 4 is opened or closed by the external force, this effect can make earphone 5 can be detained tightly on the ear or be convenient for helmet 1 wholly break away from the head when breaking away from the ear for the whole wearing of being convenient for of helmet, simultaneously under the condition that does not use the earphone, can not wholly take off the helmet, only need exert external force, through gimbal mechanism with earphone 5 open can, changed frequently take the problem of helmet 1.

Further, in order to facilitate the opening and the closing of the bracket 4 to be fixed, the bracket mechanism comprises a V-shaped groove 31 formed in the top of the rotary fixing plate 3 and a V-shaped block 32 matched with the V-shaped groove 31 (preferably, the V-shaped block 32, the rotary fixing plate 3 and the circular fixing plate 2 are all made of hard plastic), the top of the bracket 4 is rotatably connected with the bottom of the V-shaped block 32, and a limit groove 33 for placing the bracket 4 is formed in the center of the rotary fixing plate 3; in the state that the support 4 is opened or closed, the support 4 presses the V-shaped block 32 into the V-shaped groove 31, and the two integrally form a V-shaped structure 100. When the support is opened (as shown in fig. 6), a rightward force is applied to the bottom of the support 4, the whole support 4 takes a contact part (as shown in fig. 6A) with the limiting groove 33 as a fulcrum, the bottom moves rightwards, the top end of the support presses the V-shaped block 32 to move leftwards, when the V-shaped block 32 and the whole support 4 are in a straight line, the V-shaped block 32 is matched with the V-shaped groove 31, the top of the support 4 is pressed to deform downwards (the support 4 preferably has a deformed steel wire with a diameter of 3 mm), so that the support 4 passes over the highest point, the external force is stopped being applied, and the V-shaped block 32 is pressed against the left side wall of the V-shaped groove 31 under the action force of the deformation recovery of the top of the support 4 to form the V-shaped structure 100, and the bottom of the; conversely, when the stand is closed, a leftward force is applied to the bottom of the stand 4 (as shown in fig. 7), which is the same as the stand opening method.

Further in order to prevent the bracket 4 from being separated from the limiting groove 33, the edge of the limiting groove 33 is symmetrically extended with a lug 34 for preventing the bracket 4 from sliding out, so as to limit the position of the bracket 4 in the limiting groove 33 when the bracket 4 is opened and closed; be equipped with stopper 35 on the rotation fixing plate 3 that is located support 4 for the opening of restriction support 4 bottom (being used for the installation of earphone 5) prevents that under the effect of external force, this opening diminishes, damages earphone 5 or causes the unable problem of installing of earphone 5.

Further, in order to facilitate the rotation and the fitting installation of the V-shaped block 32 and the bracket 4, an arc-shaped groove 321 for the bracket 4 to be clamped in is formed at the bottom of the V-shaped block 32.

Further, in order to facilitate the installation of the stand device and the helmet 1, the center of the circular fixing plate 2 is provided with a support rod 21 for the rotation of the rotary fixing plate 3, the center of the rotary fixing plate 3 is provided with a mounting hole 36 matched with the support rod 21, and the top of the circular fixing plate 2 is further provided with a through hole 22 for fixing the support plate and the side wall of the helmet 1. The support device is preferably integrally fixed on the helmet 1 by a bolt matching with the through hole 22, and the rotation fixing plate 3 drives the support 4 and the earphone 5 to integrally rotate on the support rod 21.

The principle of the utility model is that: earphone 5 is rotatory to be set up in 4 bottoms of support to can be for helmet 1 is outside rotatory, and support 4 drives earphone 5 integral erection in the spacing groove 33 of swivelling joint board 3, and carries on spacingly through lug 34 to support 4, and the arc wall 321 cooperation of support 4 top and V type piece 32 is rotatory, V type 31 is gone into to V type piece 32 top card.

When the support is opened (as shown in fig. 6), a rightward force is applied to the bottom of the support 4, the whole support 4 takes a contact part (as shown in fig. 6A) with the limiting groove 33 as a fulcrum, the bottom moves rightwards, the top end of the support presses the V-shaped block 32 to move leftwards, when the V-shaped block 32 and the whole support 4 are in a straight line, the V-shaped block 32 is matched with the V-shaped groove 31, the top of the support 4 is pressed to deform downwards, so that the two parts cross the highest point, the external force is stopped being applied, and the V-shaped block 32 is pressed against the left side wall of the V-shaped groove 31 under the action force of the deformation recovery of the top of the support 4 to form the V-shaped structure 100, and the bottom of the support 4 drives the earphone; conversely, when the stand is closed, a leftward force is applied to the bottom of the stand 4 (as shown in fig. 7), which is the same as the stand opening method.

When wearing, can be earlier through rotatory fixed plate 3, with 5 and the support 4 integral rotation to 1 rear portion of helmet, take the back with 1 helmet again, come down 5 and the support 4 integral rotation with earphone, inwards exert external force, tightly detain 5 earphones on the ear, when opening, the operation is opposite.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
