Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, 6 and 7, the utility model provides a TWS earphone box, which comprises a cover body, a box body and an earphone hinge connecting the cover body and the box body. This earphone hinge sets up along vertical direction, and it can realize that lid 100 is rotatory to be opened and shut relative to box body 200, and supplementary lid 100 uncaps or closes the lid in the use, realizes the semi-automatic uncapping of lid 100 and closes the lid. And the limiting structure is arranged inside, so that the cover opening state can be maintained after the cover body 100 is opened, forward-rotation and reverse-rotation opening and closing can be realized, and the use convenience of the earphone box is improved.
Specifically, as shown in fig. 2-5, the earphone hinge 300 includes a movable member and a fixed member. The movable member comprises a connecting seat 303 fixed on the earphone cover and a first cam piece arranged at the center of the connecting seat 303, a jack is arranged at the center of the first cam piece, an opening on one side of the jack is provided with an accommodating groove 103a, the periphery of an opening on the other side of the jack is provided with two first arc-shaped protruding portions 103c and two first arc-shaped groove portions 103d, and the first arc-shaped protruding portions 103c and the first arc-shaped groove portions 103d are arranged in a staggered mode.
The fixing member comprises a sleeve 106, a spring member 105, and a second cam member 104. The sleeve 106 has a positioning portion around the circumference, and the positioning portion is locked to the earphone housing by screws. The second cam member 104 is slidably received within the sleeve 106 and the spring member 105 is biased by the second cam into the sleeve 106.
The center of the second cam member 104 has a center portion 104a, and the end face of the center portion 104a is provided with a second arc-shaped groove portion 104d and a second arc-shaped protrusion portion 104e corresponding to the first arc-shaped protrusion portion 103c and the first arc-shaped groove portion 103 d.
The shaft member 301 is movably arranged in the insertion hole of the first cam member, the shaft member 301 passes through the second cam member 104, and the spring is connected to the bottom of the sleeve 106 through the locking piece 107.
In this embodiment, the first cam member and the joint holder 303 are integrally joined to simplify the hinge structure.
The principle of the utility model is that:
when the earphone cover is rotated, the earphone cover drives the first cam piece to rotate relative to the second cam piece 104, the first arc-shaped protruding portion 103c of the first cam piece is turned out from the second arc-shaped groove portion 104d, so that the second cam piece 104 moves in the sleeve 106 to compress the spring piece 105, and when the first cam piece is rotated to a specific angle, the spring piece 105 ejects the second cam piece 104 to clamp the first cam piece, so that the earphone cover keeps an opening state, and a user can pick up earphones.
At the instant that the first arc-shaped projection 103c on the first cam piece and the second arc-shaped projection 104e on the second cam piece 104 are relatively staggered during the process of rotating the cover, the spring piece 105 can apply an elastic force to the second cam piece 104 to push the second cam frame upwards to assist the first cam piece in rotating the cover. In a same way, in the process of rotating the cover closing, the first cam piece can be assisted to rotate the cover closing, and automatic return is realized.
In the present embodiment, four wall portions 104b are provided on the periphery of the central portion 104a, and annular clamping grooves are formed between the four wall portions 104b and the central portion 104 a; a stopper portion 104c is disposed between one of the arc-shaped groove portions and the wall portion 104 b. A slot 103b is arranged on the first convex part of the first cam piece, two PIN PINs 302 arranged side by side are arranged in the slot 103b, and the PIN PINs 302 are inserted into the annular clamp groove.
When the first cam piece rotates relative to the second cam piece 104, the PIN 302 is driven to move in the annular clamp groove, and when the PIN 302 moves to the stopping part 104c, the movement is limited, so that the wire passing through the shaft piece 301 is prevented from being twisted.
In the embodiment, the upper end portion of the shaft member 301 is provided with an edge portion which is pressed in the accommodating groove 103a of the first cam member to press the two PIN PINs 302 in the inserting grooves 103b, so that the PIN PINs 302 are locked without providing a fastener, and the structure of the headphone hinge 300 is further simplified.
Compare with current TWS earphone box, the beneficial effects of the utility model reside in that:
(1) by adopting the first cam piece and the second cam piece 104 which are matched with each other, when the first cam piece and the second cam piece 104 rotate relatively, the first arc-shaped protrusion part 103c of the first cam piece is rotated out of the second arc-shaped groove part 104d, so that the second cam piece 104 moves in the sleeve 106 to compress the spring piece 105, when the first cam piece and the second cam piece rotate to a specific angle, the second cam piece 104 is ejected out under the action of the spring piece 105 to clamp the first cam piece, and the limiting of the first cam piece is completed.
(2) By providing the convex portions and concave portions of the first cam member and the second cam member 104 with arc shapes, the spring member 105 can exert an elastic force on the second cam member 104 at the moment when the first arc-shaped convex portion 103c of the first cam member and the second arc-shaped convex portion 104e of the second cam member 104 are relatively staggered, pushing the second cam frame upward, assisting the first cam member in rotating.
(3) Adopt the utility model provides an earphone hinge 300 can realize spacing and the automatic uncapping in the rotation of earphone lid, and simple structure does benefit to the implementation.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
