Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

The embodiment takes the automobile seat as the application scene of the music headrest.

As shown in fig. 1, 2 and 3, a music headrest with side wing turning function, a headrest base 1 is in a cuboid structure, and has a center hole 1a penetrating along the length direction, the left and right ends of the center hole 1a are both fixedly provided with a supporting seat 5, the supporting seat 5 is connected with a turnover seat 2 which is in rotating fit with the supporting seat, a music box 3 is arranged in the turnover seat 2 in a sliding way, a connecting rod mechanism 4 is arranged between the music box 3 and the turnover seat 2, the music box 3 is rotated to be turned forwards relative to the headrest base 1, and in the turning process, the music box 3 can slide out from the turning seat 2 under the drive of the connecting rod mechanism 4, thereby make music box 3 more be close to user's ear, for the user provides independent audio space, the music box that the while upset was come out also can play the parcel supporting role to user's head, makes the user more relax, has promoted the holistic travelling comfort of headrest effectively.

As shown in fig. 4, the music box 3 includes an outer casing 3a, an inner casing 3b is installed in the outer casing 3a, a speaker 3c is installed in the inner casing 3b, a cover plate 3d is installed at an open end of the outer casing 3a, and a gap is formed between an inner bottom of the outer casing 3a and an outer bottom of the inner casing 3b for facilitating layout and installation of the link mechanism 4.

As shown in fig. 3 and 5, the link mechanism 4 includes a first link 4a, a second link 4b and a third link 4c which are connected in turn, wherein one end of the first link 4a, which is far away from the second link 4b, is connected to the supporting base 5 in a rotating manner, and is parallel to the rotating axis of the turnover base 2, which is around the supporting base 5, the first link 4a and the second link 4b are connected in a rotating manner in a spherical hinge manner, the turnover base 2 is provided with a hinge shaft 2d, the middle part of the second link 4b is connected to the hinge shaft 2d in a rotating manner, and one end of the third link 4c, which is far away from the second link 4b, is connected to the outer bottom of the inner housing 3b in a rotating manner.

Because the first connecting rod 4a is parallel and not coaxial around the axis of rotation of supporting seat 5, with the upset seat 2 around the axis of rotation of supporting seat 5, so, when upset seat 2 overturned forward and opened, first connecting rod 4a can stimulate second connecting rod 4b and rotate clockwise around articulated shaft 2d for interior casing 3b has the trend of outside motion, thereby drives music box 3 outwards roll-off from in the upset seat 2.

As shown in fig. 3, the position of the flipping base 2 corresponding to the first link 4a is provided with a yielding hole 2a, and the first link 4a passes through the yielding hole 2a and is rotatably connected to the supporting base 5.

As shown in fig. 5, in order to ensure that the third link 4c can drive the music box 3 to effectively slide out in the initial state and avoid the link mechanism 4 from shaking during operation, a torsion spring 4d is installed at a position where the second link 4b is rotatably connected to the third link 4 c.

As shown in fig. 3, the turning base 2 is provided with guide flanges 2b at both sides thereof, the outer case 3a is provided with guide grooves 3a1 corresponding to the guide flanges 2b, and the guide flanges 2b are slidably fitted in the guide grooves 3a 1. By the design, the music box 3 can play a role in guiding and ensure the reliability of sliding relative to the turnover seat 2.

As shown in fig. 6, in order to prevent the music box 3 from completely escaping, a limiting boss 2c is disposed on the inner bottom of the end of the flip seat 2 away from the supporting seat 5, a limiting latch 3a2 is disposed on the outer bottom of the outer shell 3a, the limiting latch 3a2 is adapted to the limiting boss 2c and located on the same cross section, and when the music box 3 slides to the outermost end, the limiting boss 2c abuts against the limiting latch 3a2, so as to achieve a limiting effect, and prevent the music box 3 from escaping.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
