Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-3, the cab interior trim includes a headrest 1, an accommodating cavity 2 is formed in the headrest 1, a horizontal C-shaped chute 3 is formed in the upper portion of the accommodating cavity 2, a notch of the C-shaped chute 3 faces the bottom of the accommodating cavity 2, a first slider 4 and a second slider 5 are respectively arranged at two ends of the C-shaped chute 3, a first spring 6 is arranged between each of the first slider 4 and the second slider 5 and the inner wall of the accommodating cavity 2, a first fixing rod 7 is fixed at the bottom of the first slider 4, a second fixing rod 8 is fixed at the bottom of the second slider 5, a sliding hole 20 is formed in the bottom of the accommodating cavity 2, and the first fixing rod 7 and the second fixing rod 8 extend to the outside of the accommodating cavity 2 through the sliding hole 20 and slide in the sliding hole 20. Initially, the headrest 1 is mounted on a seat, the first fixing rod 7 and the second fixing rod 8 are inserted into the seat, and the first spring 6 is in a compressed state; when a dangerous situation occurs and the window breaking of the headrest 1 is needed, the headrest 1 is pulled out of the seat, the first sliding block 4 and the second sliding block 5 move oppositely under the action of the elastic force of the first spring 6 and both move towards the middle of the C-shaped sliding groove 3, and finally the first sliding block 4 and the second sliding block 5 are attached to drive the first fixing rod 7 and the second fixing rod 8 to be attached to each other, so that the first fixing rod 7 and the second fixing rod 8 are combined into a whole, the stress area is reduced, the target is more easily aligned, the success of window breaking at one time is ensured, the structure is reasonable, and a user can conveniently break the window and escape; the notch of C type spout 3 is less for first slider 4 and second slider 5 can not drop from the notch, and further, the sectional area of first slider 4 and second slider 5 is far greater than the sectional area of first dead lever 7 and second dead lever 8, and like this, it can drive first dead lever 7 and steadily slide to have ensured that first slider 4 can drive, and second slider 5 can drive second dead lever 8 and steadily slide.

A groove 40 is formed in one side, facing the second sliding block 5, of the first sliding block 4, a protrusion 50 is formed in one side, facing the first sliding block 4, of the second sliding block 5, and the protrusion 50 is meshed with the groove 40. Therefore, the first sliding block 4 and the second sliding block 5 can be immediately stopped after collision, and do not move backwards, so that the first fixing rod 7 and the second fixing rod 8 are tightly attached; further, the interlock setting can make the tie point of first dead lever 7 and first slider 4 move to first slider 4 center, and the focus moves to the middle part, is favorable to sliding of first slider 4 more, and second dead lever 8 is with second slider 5 with the same reason.

The first fixing rod 7 and the second fixing rod 8 are attached to each other in a cylindrical shape. That is to say, the radial cross-section of first dead lever 7 is semi-circular, the radial cross-section of second dead lever 8 is semi-circular, takes out at headrest 1, and first dead lever 7 and second dead lever 8 take place after the relative motion, and first dead lever 7 collides with second dead lever 8, forms complete cylindricality, has further reduced lifting surface area, has ensured that the strike just can realize broken window, has saved rescue time.

A plurality of steel balls 30 are laid on the inner wall of the C-shaped sliding groove 3, and the first sliding block 4 and the second sliding block 5 are arranged among the steel balls 30. The steel balls 30 are arranged, so that the contact area between the first sliding block 4 and the second sliding block 5 is reduced, the friction force is reduced, and the smooth degree of sliding is improved.

And second springs 9 are arranged between the first fixing rod 7 and the inner wall of the accommodating cavity 2 and between the second fixing rod 8 and the inner wall of the accommodating cavity 2. First spring 6 and second spring 9 cooperate, when providing bigger elastic force effect for first slider 4 is more even with the holistic atress of first dead lever 7, second slider 5 and second dead lever 8, and it is more steady to slide, has improved the reliability, ensures that the lifesaving operation is quick, effective.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
