Description

Technical Field

[0001] This utility model relates to the field of automotive seat equipment technology, and more specifically, to a headrest guide sleeve with an elastic bushing and an automotive seat. Background Technology

[0002] Car headrest guide sleeves are an indispensable part of car seats, used to adjust the functionality of the headrests. Currently, the manufacturing process of headrest guide sleeves is generally quite complex, involving the assembly of many parts, resulting in high production costs. Furthermore, multiple molds need to be designed during production to ensure the precision of each part.

[0003] However, most current automotive headrest guide sleeves use pure plastic guide sleeve inner ribs and elastic protrusions to control the headrest operating force, which has problems. Because plastic injection molding shrinkage can easily lead to excessively large or tight gaps after assembly, making it difficult to control the dimensions, thus affecting the amount of operating force and abnormal noise.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] 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.

[0035] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0036] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a headrest guide sleeve with an elastic bushing, including a guide sleeve tube 100 and a C-shaped elastic guide sleeve 200; the guide sleeve tube 100 is provided with a mounting seat 110 for installing the C-shaped elastic guide sleeve 200, and the C-shaped elastic guide sleeve 200 is interference-fitted with the mounting seat 110; the C-shaped elastic guide sleeve 200 has a plurality of elastic protrusions 210 for abutting against the headrest rod 300.

[0037] Specifically, the C-type elastic guide sleeve 200 is interference-fitted with the mounting seat 110 inside the guide sleeve tube body 100. Under its own elasticity and the interference fit assembly method, the C-type elastic guide sleeve 200 can be firmly fixed on the mounting seat 110 inside the guide sleeve tube body 100, eliminating the gap between the C-type elastic guide sleeve 200 and the guide sleeve tube body 100, thereby eliminating abnormal noise. In addition, the multiple elastic protrusions 210 on the C-type elastic guide sleeve 200 can abut against the outer wall of the headrest rod 300, thereby ensuring the stable operation of the headrest rod 300.

[0038] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in the optional scheme of this embodiment, the C-type elastic guide sleeve 200 is a metal guide sleeve.

[0039] The C-type elastic guide sleeve 200 includes a first C-type guide sleeve 220, a second C-type guide sleeve 230, and an elastic rib 210; the first C-type guide sleeve 220 and the second C-type guide sleeve 230 are connected by a plurality of elastic ribs 210.

[0040] Specifically, the C-type elastic guide sleeve 200 can be made of metal. The dimensional tolerance of the metal C-type elastic guide sleeve 200 can be controlled within ±0.03mm, and the dimensions are easy to manage, thereby ensuring the assembly of the C-type elastic guide sleeve 200 with the guide sleeve tube body 100.

[0041] In addition, the mounting base 110 has an L-shaped cross-section. When the C-shaped elastic guide sleeve 200 is assembled with the mounting base 110, the first C-shaped guide sleeve 220 abuts against the bottom of the mounting base 110, and the second C-shaped guide sleeve 230 is unrestrained. When there is a large error in the dimensional assembly of the headrest rod 300 and the C-shaped elastic guide sleeve 200, the headrest rod 300 can press the elastic rib 210, and the elastic rib 210 drives the second C-shaped guide sleeve 230 to move, thereby ensuring that the headrest rod 300 and the elastic rib 210 are within the normal range, and avoiding the inconvenience of operating the headrest rod 300 due to excessive pressure between the headrest rod 300 and the elastic rib 210.

[0042] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in an optional embodiment, the protruding direction of the elastic rib 210 is towards the headrest rod 300.

[0043] Among them, the cross-section of the elastic rib 210 is arc-shaped.

[0044] Specifically, the elastic ribs 210 can abut against the outer wall of the headrest rod 300. When the headrest rod 300 is inserted into the C-shaped elastic guide sleeve 200, the headrest rod 300 abuts against multiple elastic ribs 210.

[0045] The guide sleeve body 100 has an observation hole 130 located at the mounting base 110. When installing the C-type elastic guide sleeve 200, the observation hole 130 can be used to conveniently observe whether the C-type elastic guide sleeve 200 is installed.

[0046] Meanwhile, the observation hole 130 can improve the heat dissipation of the C-type elastic guide sleeve 200.

[0047] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in the optional embodiment, the mounting base 110 is provided with a guide rail 120, and the opening of the C-shaped elastic guide sleeve 200 can be adapted to the guide rail 120.

[0048] Specifically, the mounting base 110 is provided with a guide rail 120, the length of which extends from the mounting base 110 to the opening of the guide sleeve body 100, thereby making it convenient for workers to install the C-type elastic guide sleeve 200.

[0049] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in the optional embodiment, the C-type elastic guide sleeve 200 is provided with a wear-resistant protective layer.

[0050] The wear-resistant protective layer is made of polytetrafluoroethylene.

[0051] Specifically, a wear-resistant protective layer is provided on the C-type elastic guide sleeve 200. The wear-resistant protective layer can be made of polytetrafluoroethylene. In addition, those skilled in the art can choose the material of the wear-resistant protective layer according to actual needs, which will not be elaborated here.

[0052] In addition, the wear-resistant protective layer not only improves the wear life of the C-type elastic guide sleeve 200, but also first comes into contact with the headrest rod 300, reducing the friction between the headrest rod 300 and the C-type elastic guide sleeve 200, thus improving the smoothness of operation.

[0053] This embodiment provides an automobile seat, including a headrest guide sleeve with an elastic bushing.

[0054] Specifically, the car seat provided in this embodiment has the advantages of the headrest guide sleeve with elastic bushing mentioned above compared with the prior art, which will not be repeated here.

[0055] 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.
