Detailed Description
As shown in fig. 1 and 2, a novel polyurethane injection-molded multifunctional car seat headrest, a headrest body is mainly formed by buckling a front cover housing S10 and a rear cover housing S13, a carrier member S11 and a sliding member S12 are arranged in a cavity formed by buckling the front cover housing S10 and the rear cover housing S13, the upper end of a headrest rod S7 is fixedly connected with the carrier member S11, the buckled front cover housing S10 and rear cover housing S13 are connected with the sliding member S12, and the sliding member S12 slides back and forth in a sliding cavity of the carrier member S11 through a locking mechanism to drive the headrest to move back and forth; after the front cover shell S10 and the rear cover shell S13 are matched, the adhesive tape strip S14 is firstly used for sealing the technical hole S10.4 on the headrest front cover shell S10 to ensure that the outer side of the headrest function module is sealed, and then the modified polyurethane layer S1 is injected to form the headrest assembly. The invention uses a secondary injection molding process to melt and coat the modified polyurethane material on the outer layer of the headrest functional module with the sealing effect. The method directly replaces the design, production and subsequent assembly process of the foaming product and the skin product, thereby greatly reducing the development difficulty of the product, shortening the verification period of the product, simplifying the production process of the product and saving the related cost of the product.
As shown in fig. 3 and 4, in order to ensure that the front cover piece S10 and the rear cover piece S13 of the headrest can move together with the sliding piece S12, a plurality of claws S10.1 are arranged on the outer edge of the inner surface of the front cover piece S10, and the claws S10.1 are matched and connected with corresponding grooves of the rear cover piece S13; the inner surface of the front cover shell S10 is provided with a clamping joint S10.2, and the clamping joint S10.2 is clamped and matched with a clamping hole S12.1 arranged at a position corresponding to the surface of the sliding piece S12. The headrest rod S7 is fixed, the upper end head S7.1 of the headrest rod is inserted into the headrest rod groove S11.1 of the carrier piece S11, so the carrier piece S11 is also fixed and fixed like the headrest rod, when the surface of the polyurethane layer S1 of the headrest assembly is pressed, the front cover S10 or the rear cover S13 moves forwards or backwards under the pushing force transmitted by the polyurethane layer S1, and the whole headrest is pushed, so that the forward or backward sliding of the polyurethane outer layer S1 and the whole headrest functional system is realized.
As shown in fig. 5 to 8, the specific sliding locking function is realized by the specific structure of the internal locking mechanism, which is as follows: a locking groove S12.4 is formed in the bottom surface of a horizontally arranged sliding part S12, a locking piece S2 is vertically arranged on a carrier piece S11 in a sliding connection mode, the top of the locking piece S2 is inserted into the locking groove S12.4, a return spring I S9.2 is arranged on the outer side of the locking piece S2, the upper end of the return spring I S9.2 is connected with a spring hook S11.4 at the upper end of a carrier piece S11, and the lower end of the return spring I S9.2 is connected with a spring hook S2.3 at the bottom of the locking piece S2; the bottom of the locking piece S2 is provided with a linkage mechanism which provides external power for the locking piece S2 to move up and down.
The specific structure of the linkage mechanism is that a slide way S11.3 on the bottom surface of a carrier piece S11 is provided with a sliding connection transmission piece S6, the upper surface of the transmission piece S6 is provided with an obliquely arranged pushing tongue S6.3, the bottom of a locking piece S2 is provided with a slope S2.2 with an opening, and the pushing tongue S6.3 is contacted with the upper surface of the slope S2.2; the side surface of the front cover shell S10 is provided with a button box matching notch, and the side wall of the notch is provided with a button box back-off matching groove (S10.3) so that the button box is clamped with the button box back-off (S5.2) to realize the fixation of the button box S5.
