Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a headrest guide sleeve for vehicles. Background Art

[0002] With the continuous development of the automotive industry, consumers have higher and higher requirements for the quality of automobiles. When a vehicle headrest is installed on a seat, the skeleton is usually inserted into a headrest guide sleeve fixedly installed on the seat backrest. The headrest guide sleeve includes a guide tube and a cap, and the cap is connected to the guide tube by snap connection. During the driving of the vehicle, abnormal noises are likely to occur due to unstable snap connection or even detachment, affecting the driving experience. Content of the Utility Model

[0003] To solve the abnormal noise generated by the headrest guide sleeve in the vehicle, the utility model provides a headrest guide sleeve for vehicles. The headrest guide sleeve for vehicles includes a cap and a guide tube. A plurality of snap protrusions and at least one axial snap protrusion are arranged on the inner wall of the cap, and limiting buckles are arranged on both sides of the axial snap protrusion; the guide tube includes a snap disc, and a slot is arranged on the snap disc; when the cap is snap-connected to the guide tube, the axial snap protrusion is clamped in the slot, and the limiting buckles and the snap protrusions are clamped on both sides of the snap disc. In this way, the headrest guide sleeve of the utility model uses the snap protrusions and the limiting buckles to snap-connect the cap and the snap disc on the guide tube, which can effectively increase the pulling force for separating the snap-connected cap and the guide tube, improve the connection stability between the cap and the guide tube, and avoid abnormal noises generated by the separation of the cap and the guide tube of the headrest guide sleeve of the utility model during the driving of the vehicle; by using the cooperation between the axial snap protrusion and the slot on the snap disc, it is avoided that abnormal noises are generated due to the shaking and dislocation of the guide tube and the cap, affecting the riding experience.

[0004] Preferably, the axial snap protrusion is located at the end of the snap protrusion. In this way, it is possible to avoid mutual interference between the axial snap protrusion and the snap protrusion during the snap connection, affecting the assembly efficiency of the headrest guide sleeve of the utility model. Further, the axial snap protrusion and the snap protrusion are connected into an L-shaped structure. In this way, the axial snap protrusion and the connecting protrusion are connected to form an L-shaped structure, which can not only improve the strength of the axial snap protrusion and the connecting protrusion, but also facilitate the snap connection and improve the assembly efficiency of the headrest guide sleeve of the utility model.

[0005] Preferably, the limiting buckle is an L-shaped structure. In this way, the limiting buckle in the shape of an L has a stable structure and high strength, which can improve the snap connection stability between the cap and the guide tube in the headrest guide sleeve of the utility model.

[0006] Preferably, the clamping protrusions are evenly distributed on the same circumference. In this way, when the cap of the vehicle headrest guide sleeve of the present invention is clamped and connected to the guide tube, the clamping protrusions clamped with the clamping disc are evenly stressed, which can improve the qualified rate of assembly of the vehicle headrest guide sleeve of the present invention and reduce the waste caused by unqualified assembly.

[0009] Figure 3 is Figure 2 the A-A cross-sectional structural diagram in DETAILED DESCRIPTION OF THE EMBODIMENTS

[0010] Next, in combination with Figures 1 to 3 , the vehicle headrest guide sleeve of the present invention will be described in detail.

[0011] As shown in Figures 1 to 3As shown in the figure, the vehicle headrest guide sleeve of the present utility model comprises a cap 1 and a guide tube 2. A plurality of clamping protrusions 11 and at least one axial clamping protrusion 12 are arranged on the inner wall of the cap 1, and limiting buckles 13 are arranged on both sides of the axial clamping protrusion 12; the guide tube 2 comprises a clamping disc 21, and a clamping groove 211 is arranged on the clamping disc 21; when the cap 1 is clamped and connected with the guide tube 2, the axial clamping protrusion 12 is clamped in the clamping groove 211, and the limiting buckles 13 and the clamping protrusions 11 are clamped on both sides of the clamping disc 21, that is, the clamping disc 21 is clamped by the limiting buckles 13 and the clamping protrusions 11. In this way, the vehicle headrest guide sleeve of the present utility model clamps and connects the cap 1 and the clamping disc 21 on the guide tube 2 by using the clamping protrusions and the limiting buckles 13, which can effectively increase the pulling force for separating the cap 1 and the guide tube 2 in the clamping connection, improve the connection stability between the cap 1 and the guide tube 2, and avoid the generation of abnormal noises due to the separation of the cap 1 and the guide tube 2 during the driving of the vehicle; by using the cooperation between the axial clamping protrusion 12 and the clamping groove 211 on the clamping disc 21, the generation of abnormal noises caused by the shaking and misalignment of the guide tube 2 and the cap 1 is avoided, which affects the driving experience. Preferably, the axial clamping protrusion 12 is located at the end of the clamping protrusion 11. In this way, the interference between the axial clamping protrusion 12 and the clamping protrusion 11 during the clamping process can be avoided, and the assembly efficiency of the vehicle headrest guide sleeve of the present utility model is affected. Preferably, the axial clamping protrusion 12 and the clamping protrusion 11 are connected into an L-shaped structure. In this way, the axial clamping protrusion 12 and the connecting protrusion 11 are connected to form an L-shaped structure, which can not only improve the strength of the axial clamping protrusion 12 and the connecting protrusion 11, but also facilitate the clamping connection and improve the assembly efficiency of the vehicle headrest guide sleeve of the present utility model. Preferably, the limiting buckle 13 is an L-shaped structure. In this way, the limiting buckle 13 in the L-shaped structure has stable structure and high strength, and can improve the clamping stability between the cap 1 and the guide tube 2 in the vehicle headrest guide sleeve of the present utility model. Preferably, the clamping protrusions 11 are evenly distributed on the same circumference. In this way, when the cap 1 and the guide tube 2 in the vehicle headrest guide sleeve of the present utility model are clamped and connected, the clamping protrusions 11 clamped with the clamping disc 21 are uniformly stressed, which can improve the qualified rate of the assembly of the vehicle headrest guide sleeve of the present utility model and reduce the waste caused by unqualified assembly.
