Description of drawings
Fig. 1 is the structure exploded perspective view of headrest base in the utility model.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, clear and definite, referring to the accompanying drawing embodiment that develops simultaneously the utility model is further described.
As shown in Figure 1, this headrest base 200 is arranged in the groove of headrest 100, with headrest 100 mutual engagement connections.
Described headrest base 200 comprises bed plate 210 and trim board 220: four side projections of described bed plate 210, centre are sunk groove positions; Side at bed plate 210 is provided with a plurality of draw-in grooves 212, being provided with a plurality of card article 221(card article 221 quantity on the side of described trim board 220 equates with draw-in groove 212), described trim board 220 cooperates with draw-in groove 212 in the groove position that is installed in bed plate 210 by card article 221, and described card article 221 can be along draw-in groove 212 up-and-down movements; Also be provided with device for ejecting on the described bed plate 210, be used for driving trim board 220 and automatically upspring along draw-in groove 212.
Described device for ejecting comprises spring groove 211 and the spring 214 that is arranged on the bed plate 210 groove positions, spring 214 1 end linking springs grooves 211, and the other end connects trim board 220; Described spring groove 211 and spring 214 can arrange according to actual conditions a plurality of.
In order to make trim board 220 stressed even, in the present embodiment, described spring groove 211 arranges 4, is separately positioned on four angles of bed plate 210 groove positions; Described spring 214 arranges 4.
Also be provided with connector 213 on the described bed plate 210, be provided with connector hole 222 on the trim board 220, described connector 213 passes connector hole 222.Described connector 213 is used for connecting the active device of headrest 100 and display terminal.
When display terminal does not need from resting the head on 100 dismounting or when taking out separately, headrest base 200 is installed in the groove of headrest 100, the card article 221 of trim board 220 is fastened in the groove position 212 of bed plate 210, and display terminal is installed in the groove position of bed plate 210; At this moment, because the effect of display terminal, spring 214 is in compressive state, and trim board 220 can not bounce.
When display terminal from rest the head on 100 dismounting or take out separately after, because lacked the pressure of display terminal, the spring 214 that is between bed plate 210 and the trim board 220 extends automatically because of the effect of elastic force, trim board 220 draw-in groove 212 along bed plate 210 under the effect of spring 214 moves, like this, and under dismounting in the display terminal, trim board 220 is upspring automatically, filled up the cavity of leaving over because of behind the dismounting display terminal, both attractive in appearance, guaranteed again safety.
This headrest understructure is simple, and is easy for installation, and after display terminal disassembled from headrest, the automatic spring decoration panel blocks the cavity, and was both attractive in appearance, guaranteed again safety.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or conversion, all these improvement and conversion all should belong to the protection domain of the utility model claims.
