DETAILED DESCRIPTION

In order to better understand the present disclosure, a detailed description of example embodiments referring to the drawings will be described hereinafter.

Referring to FIGS. 1 to 4, the present application discloses a headrest which can be applied to electrical bicycles. The headrest includes a front casing 1, a rear casing 2 fixed to the front casing 1 and a headrest support fixed between the front casing 1 and the rear casing 2 to facilitate reliably keeping the contour of the headrest. The headrest support includes a metal plate 3 and a stationary rod 4. The metal plate 3 is fixed to a top of the stationary rod 4 and clamped between the front casing 1 and the rear casing 2. The stationary rod 4 is fixed to the rear casing 2 and extends downwardly beyond the rear casing 2. The stationary rod 4 is a round tube and is of a U-shaped configuration as a whole.

The front casing 1 includes an outer cortical layer 11, a plastic piece 12 and a sponge 14 sandwiched between the outer cortical layer 11 and the plastic piece 12. The front casing 1 has security protection function. That is to say, when the human head backwardly collides the front casing 1, since the front casing 1 is soft, it can be provided with excellent buffering protection of the head so as to facilitate avoiding accident injury.

The plastic piece 12 includes a main portion 121 extending backwardly and a peripheral portion 122 enclosing the main portion 121. The metal piece 3 resists against the main portion 121. The peripheral portion 122 includes a plurality of hooks 123, the rear casing 2 includes a plurality of fixing holes 21, and the hooks 123 are lockable with the fixing holes 21 so as to fasten the front casing 1 and the rear casing 2 together.

The rear casing 2 includes a recessed section 22 and a peripheral section 23 enclosing the recessed section 22. The recessed section 22 includes an upper embossment 221 and a lower embossment 222 below the upper embossment 221. The stationary rod 4 includes a horizontal lever 41 abutting against a top side of the upper embossment 221 and a pair of vertical levers 42 extending downwardly from lateral sides of the horizontal lever 41. The vertical levers 42 clamp opposite sides of the upper embossment 221.

The lower embossment 222 includes a pair of first holes 223, the peripheral section 23 includes a pair of second holes 231 corresponding to the first holes 223, and the vertical levers 42 extend through the first holes 223 and the second holes 231 in turn and further extend beyond the peripheral section 23.

Each of the upper embossment 221 and the lower embossment 222 includes a restricting hole 224, and the metal piece 3 includes a mounting hole 31 corresponding to the restricting hole 224. The headrest further includes a fixing member for mating with the restricting hole 224 and the mounting hole 31. The fixing member can be a screw.

The headrest includes a support member 5 supporting a bottom side and a rear side of the rear casing 2. The support member 5 includes a pair of through holes 51 through which the vertical levers 42 extend downwardly.

The headrest further includes a restricting member 6 mounted to the support member 5. The support member 5 includes a protrusion 52 extending downwardly. The restricting member 6 includes a bottom U-shaped portion 61 and a pair of transverse portions 62 horizontally extending from opposite sides of the U-shaped portion 61. Each transverse portion 62 includes a sleeve portion 63. The U-shaped portion 61 surrounds a bottom side and opposite lateral sides of the protrusion 52. The sleeve portions 63 are received in the through holes 51. The vertical levers 42 extend through the sleeve portions 63 and extend beyond the support member 5. The vertical levers 42 are positioned at lateral sides of the U-shaped portion 61 and the protrusion 52. The restricting member 6 further includes a pair of vertical pieces 64 extending upwardly from opposite ends of the transverse portions 62 for fixing with other components of the electrical bicycle. The restricting member 6 is mainly used for downwardly resisting against the vehicle framework for preventing that the headrest offsets from the normal position because of the downward movement of the headrest.

In conclusion, the description of the above embodiment is only used for the understanding of the present application. It should be noted that, those skilled in the art may make many improvements and modifications to the present application without departing from the principle of the present application, and these improvements and modifications also fall into the protection scope of the claims of the present application.
