[0040] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.
[0041] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, this embodiment provides a swing headrest with a headrest rod movement groove shielding structure, including a headrest rod 100, a headrest body 200, a headrest swing assembly 300, and a shielding assembly 400; the headrest swing assembly 300 is installed inside the headrest body 200, and the headrest body 200 has a movement groove 210; one end of the headrest rod 100 is connected to the headrest swing assembly 300, and the other end of the headrest rod 100 extends out of the headrest body 200 from the movement groove 210; the shielding assembly 400 includes a headrest slide bracket 410, a headrest follow-up shielding curtain 420, and a reset elastic member 430; the headrest slide bracket 410 is disposed inside the headrest body 200, the headrest follow-up shielding curtain 420 is slidably disposed on the headrest slide bracket 410, and the reset elastic member 430 is disposed between the headrest slide bracket 410 and the headrest follow-up shielding curtain 420, so that the headrest follow-up shielding curtain 420 has a tendency to shield the movement groove 210.
[0042] Specifically, during use, the user triggers the headrest swing assembly 300 by using the unlock button 310 or other triggering components. This causes the headrest swing assembly 300 to swing relative to the headrest rod 100, which in turn causes the headrest body 200 to swing relative to the headrest rod 100. During the swing of the headrest body 200 relative to the headrest rod 100, as the headrest rod 100 moves relative to the motion groove 210 on the headrest body 200, that is, during the process of the headrest body 200 swinging from an inclined position to a vertical position, the headrest follow-up curtain 420, which abuts against the headrest rod 100, can move downward under the action of the reset elastic member 430. This allows the headrest follow-up curtain 420 to block the motion groove 210, preventing external debris from entering the headrest body 200 through the motion groove 210, avoiding jamming, and improving the aesthetics of the headrest body 200.
[0043] The headrest swing assembly 300 and the headrest rod 100 are fixedly connected.
[0044] The headrest rod 100 is installed on the seat back.
[0045] See Figure 1 - Figure 7 As shown, in the optional solution of this embodiment, the headrest slide bracket 410 is provided with a guide slide groove 411, and the headrest follow-up shielding curtain 420 is provided with a slider 421 adapted to the guide slide groove 411.
[0046] Specifically, the headrest slide bracket 410 is fixedly installed inside the headrest body 200. The headrest slide bracket 410 is annular, and guide grooves 411 are provided on both sides of the headrest slide bracket 410. A slider 421 is provided on the headrest follow-up curtain 420, and the headrest follow-up curtain 420 can slide on the headrest slide bracket 410.
[0047] The reset elastic element 430 is disposed between the headrest slide bracket 410 and the headrest follower curtain 420, so that the headrest follower curtain 420 on the headrest slide bracket 410 has a downward tendency. Thus, after the headrest rod 100 swings, the headrest follower curtain 420 can move downward under the action of the reset elastic element 430, thereby blocking the motion groove 210 on the main headrest body 200.
[0048] In an optional embodiment, a guide rod 412 is provided on the headrest slide bracket 410, and a guide sleeve 422 adapted to the guide rod 412 is provided on the headrest follow-up curtain 420. A reset elastic member 430 is sleeved between the guide rod 412 and the guide sleeve 422 so that the reset elastic member 430 pushes the headrest follow-up curtain 420 to abut against the headrest rod 100.
[0049] Specifically, a guide rod 412 is provided on the headrest slide bracket 410, and a guide sleeve 422 is provided on the headrest follow-up curtain 420. When the headrest follow-up curtain 420 is slidably installed on the headrest slide bracket 410, the guide rod 412 is located inside the guide sleeve 422, and the reset elastic member 430 is sleeved between the guide rod 412 and the guide sleeve 422. The arrangement of the guide rod 412 and the guide sleeve 422 enables the reset elastic member 430 to work stably.
[0050] In an optional embodiment, the headrest follow-up curtain 420 is provided with multiple pre-tightening sliders 423 on both sides of its edge, and the pre-tightening sliders 423 can contact the bottom of the guide groove 411.
[0051] The headrest-following blind 420 has two pre-tightening sliders 423 on each side edge.
[0052] Specifically, multiple pre-tightening sliders 423 are provided on both sides of the headrest-following curtain 420. When the headrest-following curtain 420 is slidably installed on the headrest slide bracket 410, the pre-tightening sliders 423 on the headrest-following curtain 420 can contact the bottom of the guide slide 411, thereby improving the stability of the headrest-following curtain 420, preventing the headrest-following curtain 420 from shaking, and reducing the generation of noise.
[0053] In an optional embodiment, the headrest-following blind 420 has multiple horizontally placed spring claws 424 on both sides, and the multiple horizontally placed spring claws 424 are located between two pre-tightening sliders 423.
[0054] The headrest-following blind 420 has multiple vertically arranged spring claws 425 on both sides, and the multiple vertically arranged spring claws 425 are located between two pre-tightening sliders 423.
[0055] Specifically, multiple horizontal spring claws 424 and multiple vertical spring claws 425 are provided on both sides of the headrest follow-up curtain 420. The arrangement of the horizontal spring claws 424 and vertical spring claws 425 enables the headrest follow-up curtain 420 to be stably mounted on the headrest slide bracket 410. This not only allows the headrest follow-up curtain 420 to slide smoothly on the headrest slide bracket 410 under the action of the reset spring member 430, but also prevents shaking and reduces the probability of jamming.
[0056] In an optional embodiment, the headrest swing assembly 300 includes an unlock button 310, an unlock transmission component 320, a rotating component 330, and a rotating rod 340. The rotating component 330 is fixedly disposed inside the headrest body 200, and the unlock button 310 is disposed on the headrest body 200. The unlock button 310 is connected to the rotating component 330 through the unlock transmission component 320. The rotating component 330 is connected to the headrest rod 100 through the rotating rod 340, so that the rotating rod 340 drives the headrest rod 100 to swing.
[0057] Specifically, when the user triggers the unlock button 310, the unlock button 310 moves the transmission component, which can be a transmission rod. The transmission rod triggers the rotating component 330 to rotate, and the rotating component 330 can drive the rotating rod 340 to rotate. The rotating rod 340 then causes the headrest rod 100 to swing.
[0058] The rotating component 330 includes a rotating housing and a torsion spring. The rotating housing is fixedly installed inside the headrest body 200, and the torsion spring is installed inside the rotating housing. The torsion spring is located between the rotating housing and the rotating rod 340. The unlocking button 310 can control the release of the torsion spring, thereby controlling the rotation of the rotating rod 340, and thus controlling the swing of the headrest rod 100.
[0059] The headrest body 200 is equipped with a damping gear 220, and the rotating rod 340 is equipped with a passive gear 350 that is compatible with the damping gear 220. The damping gear 220 and the passive gear 350 enable the headrest rod 100 to swing stably and slowly.
[0060] The rotating rod 340 and the headrest rod 100 are welded together.
[0061] This embodiment provides an automobile seat, including a swing headrest with a headrest rod movement groove shielding structure.
[0062] Specifically, the car seat provided in this embodiment has the advantages of the swing headrest with the headrest rod movement groove shielding structure mentioned above compared with the prior art, which will not be repeated here.
[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
