[0044] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0045] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.
[0046] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, this embodiment provides an anti-shaking and anti-noise headrest guide sleeve, including a guide sleeve body 100, a clamping spring 200, and a fixing elastic element 300. The guide sleeve body 100 has multiple mounting slots 110, and the clamping spring 200 is located in the mounting slots 110. One end of the clamping spring 200 is fixedly connected to the side wall of the mounting slot 110. The fixing elastic element 300 is disposed on the guide sleeve body 100, and the middle part of the fixing elastic element 300 covers the clamping spring 200 so that the cantilever end of the clamping spring 200 extends into the interior of the guide sleeve body 100, and the clamping spring 200 can abut against the side wall of the headrest rod inside the guide sleeve body 100.
[0047] Specifically, the anti-sway and anti-noise headrest guide sleeve is fixedly installed on the seat back. The headrest rod is inserted into the guide sleeve body 100 of the anti-sway and anti-noise headrest guide sleeve. The fixing elastic element 300 is installed on the guide sleeve body 100. The fixing elastic element 300 can press the cantilever end of the clamping spring 200, so that the cantilever end of the clamping spring 200 extends into the interior of the guide sleeve body 100, thereby causing the cantilever end of the clamping spring 200 to abut against the outer wall of the headrest rod. This ensures a stable connection between the headrest rod and the guide sleeve body 100, preventing the headrest rod from shaking arbitrarily and avoiding abnormal noise from the headrest rod. During use, when the user moves the headrest rod up and down, and the headrest rod slides relative to the clamping spring 200, the clamping spring 200 does not restrict the movement of the headrest rod, thus not reducing the operability of the headrest rod.
[0048] The guide sleeve body 100 has multiple raised fixing ribs 130 on its inner wall. When the headrest rod is inserted into the guide sleeve body 100, the outer wall of the headrest rod contacts the multiple raised fixing ribs 130. The clamping spring 200 can press the outer wall of the headrest rod under the pressure of the fixing elastic element 300, so that the clamping spring 200 presses the headrest rod tightly. The setting of multiple raised fixing ribs 130 can not only improve the stability of the headrest rod, but also control the gap between the headrest rod and the inner wall of the guide sleeve body 100, improve the smoothness of the operation of the headrest rod, and improve the operability of the headrest rod.
[0049] It should be noted that a mounting seat 120 for mounting and fixing the elastic element 300 is provided on the side wall of the guide sleeve body 100. The mounting slot 110 and the mounting seat 120 are provided on different side walls of the guide sleeve body 100, and mounting seats 120 are provided on both sides of the mounting slot 110. The two ends of the fixing elastic element 300 are respectively installed in the mounting seats 120 on both sides of the mounting slot 110, thereby improving the connection stability between the fixing elastic element 300 and the guide sleeve body 100.
[0050] It should be noted that a protective sleeve 500 is provided on the outside of the guide sleeve body 100 to protect the fixed elastic element 300 and other components.
[0051] See Figures 1-9 As shown, in the optional scheme of this embodiment, the fixed elastic element 300 is made of elastic steel wire, which includes an elastic buckle part 310 and an elastic abutment part 320; both ends of the elastic abutment part 320 are provided with elastic buckle parts 310; the clamping spring piece 200 is provided with an abutment groove 210 that is adapted to the elastic abutment part 320.
[0052] Specifically, the U-shaped elastic buckle 310 of the fixed elastic element 300 is installed in the mounting base 120, and the elastic abutment part 320 of the fixed elastic element 300 is engaged in the abutment groove 210 of the clamping spring 200. The fixed elastic element 300 can press the cantilever end of the clamping spring 200 to move towards the inside of the guide sleeve body 100, and the clamping spring 200 can protrude from the inner wall of the guide sleeve body 100.
[0053] In addition, the elastic buckle 310 is U-shaped so that the elastic buckle 310 can move closer to or further away from the clamping spring 200. When the user adjusts the headrest bar, the headrest bar can drive the clamping spring 200 to move outward of the guide sleeve body 100, further improving the smoothness of the headrest bar operation.
[0054] See Figures 1-9 As shown, in the optional embodiment, the anti-shaking and anti-noise headrest guide sleeve also includes an unlocking switch ring 400. The unlocking switch ring 400 is inserted into the guide sleeve body 100. The unlocking switch ring 400 has a locking block 410 that can be adapted to the slot on the headrest rod. A return spring 420 is provided between the unlocking switch ring 400 and the guide sleeve body 100 so that the unlocking switch ring 400 has a tendency to disengage from the guide sleeve body 100.
[0055] The guide sleeve body 100 has a switch channel 140 for the unlocking switch ring 400 to be inserted. The guide sleeve body 100 is provided with a guide rod 141 inside the switch channel 140. One end of the reset spring 420 is sleeved on the guide rod 141. The end of the unlocking switch ring 400 that extends into the switch is provided with an assembly groove 430. The other end of the reset spring 420 is inserted into the assembly groove 430.
[0056] The guide sleeve body 100 is provided with a limit groove 142 at the opening of the switch channel 140, and the unlocking switch ring 400 is provided with a limit block 440 that is adapted to the limit groove 142 at the end away from the assembly groove 430.
[0057] Specifically, when the headrest rod is inserted into the guide sleeve body 100, the slot on the headrest rod can engage with the locking block 410 on the unlocking switch ring 400, thereby locking the headrest rod. When the seat headrest needs to be adjusted, i.e. the headrest rod is adjusted, the user presses the unlocking switch ring 400, causing the unlocking switch ring 400 to move into the switch channel 140 on the guide sleeve body 100. At this time, the locking block 410 on the unlocking switch ring 400 moves away from the slot of the headrest rod, and the user can then adjust the headrest rod up and down.
[0058] During this process, when the user presses the unlocking switch ring 400, the unlocking switch ring 400 can compress the reset spring 420, so that the reset spring 420 is in a compressed state. When the user releases the unlocking switch ring 400, the reset spring 420 drives the unlocking switch ring 400 to reset. During the process of the unlocking switch ring 400 being pressed and reset, the limiting block 440 on the unlocking switch ring 400 always slides within the limiting groove 142 on the guide sleeve body 100.
[0059] In addition, a guide rail 143 is provided in the switch channel 140, and a guide groove 450 is provided on the unlocking switch ring 400. The movement direction of the unlocking switch ring 400 is restricted by the cooperation of the guide rail 143 and the guide groove 450.
[0060] This embodiment provides a car seat, including a headrest guide sleeve that prevents shaking and abnormal noise.
[0061] Specifically, the car seat provided in this embodiment has the advantages of the aforementioned anti-shaking and anti-noise headrest guide sleeve compared with the prior art, which will not be repeated here.
[0062] 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
