Description

Technical Field

[0001] This utility model relates to the field of automotive seats, and in particular to a novel integrated concealed lock guide sleeve. Background Technology

[0002] Car seat headrests are auxiliary devices designed to improve passenger comfort and safety. In movable headrests, a headrest guide sleeve is usually installed at the connection point between the headrest rod and the seat back frame.

[0003] The existing headrest guide sleeves are complex to manufacture, have poor replaceability, and are inconvenient for headrest installation; in addition, the unlocking button of the headrest guide sleeve has the problem of accidental activation. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a new type of integrated concealed lock guide sleeve, which integrates the headrest guide sleeve cover onto the headrest guide sleeve body to reduce manufacturing and assembly costs.

[0005] This utility model provides a novel integrated concealed lock guide sleeve, comprising: a headrest guide sleeve body, a headrest guide sleeve cover integrally formed on the upper end of the headrest guide sleeve body, an unlocking button installed inside the headrest guide sleeve cover, and a V-shaped retaining spring that is linked to the unlocking button and located inside the headrest guide sleeve cover; an unlocking clearance hole is provided on one side of the headrest guide sleeve cover, the unlocking end of the unlocking button passes through the unlocking clearance hole and is installed inside the headrest guide sleeve cover, the pressing end of the unlocking button is flush with the outer edge of the headrest guide sleeve cover, and one end of the V-shaped retaining spring abuts against the headrest guide sleeve cover. On the inner wall, the other end of the V-shaped retaining spring is fixedly connected to the unlocking end of the unlocking button. The unlocking end of the unlocking button is provided with a strip-shaped hole to avoid the headrest rod and an unlocking block for engaging in the height adjustment slot of the headrest rod. By pressing the pressing end of the unlocking button in the horizontal direction, the unlocking end of the unlocking button overcomes the elastic force of the V-shaped retaining spring, causing the unlocking block of the unlocking button to separate from the height adjustment slot of the headrest rod. After unlocking, the headrest rod can be height adjusted. When the pressing end of the unlocking button is released, the V-shaped retaining spring rebounds, causing the unlocking block to engage in the height adjustment slot of the headrest rod.

[0006] As a preferred embodiment of this utility model, the bottom surface of the headrest guide cover is provided with a limiting strip groove, and the bottom of the unlock button is provided with a limiting slider corresponding to the position of the limiting strip groove. The limiting slider of the unlock button is engaged in the limiting strip groove. The limiting slider is used to prevent the unlock button from popping out of the headrest guide cover due to excessive rebound force of the V-shaped retaining spring.

[0007] As a preferred embodiment of this invention, the unlocking block has an embedded slot inside for inserting a V-shaped retaining spring.

[0008] The beneficial effects of this utility model are as follows:

[0009] 1. This utility model integrates the headrest guide cover onto the headrest guide body, thereby reducing manufacturing and assembly costs while achieving the functions of the headrest guide, resulting in better economic benefits.

[0010] 2. The gap between the unlocking button in the Y direction and the outer edge of the headrest guide sleeve body is very small. If the unlocking button is accidentally touched, the headrest rod cannot be unlocked due to its short compressible stroke, which effectively prevents the headrest rod from coming off due to misoperation.

[0011] 3. This utility model has the advantages of simple structure, good stability, low manufacturing cost, and assembly error prevention features. Moreover, since the headrest guide cover is integrated into the headrest guide body, manual assembly takes less time. In the case of limited layout space, it can cooperate with the seat to limit the headrest position. The unlocking V-shaped retaining spring is fixed together with the unlocking button by inlay injection molding, which improves the structural strength of the unlocking button.

[0018] See Figure 1-4As shown, this embodiment provides a novel integrated concealed lock guide sleeve, comprising: a headrest guide sleeve body 1, a headrest guide sleeve cover 2 integrally formed on the upper end of the headrest guide sleeve body 1, an unlocking button 3 installed inside the headrest guide sleeve cover 2, and a V-shaped retaining spring 4 linked to the unlocking button 3 and located inside the headrest guide sleeve cover 2; an unlocking clearance hole 201 is provided on one side of the headrest guide sleeve cover 2, the unlocking end 301 of the unlocking button 3 passes through the unlocking clearance hole 201 and is installed inside the headrest guide sleeve cover 2, the pressing end 302 of the unlocking button 3 is flush with the outer edge of the headrest guide sleeve cover 2, one end of the V-shaped retaining spring 4 abuts against the inner wall of the headrest guide sleeve cover 2, and the other end of the V-shaped retaining spring 4 is fixedly connected to the unlocking end 301 of the unlocking button 3, the unlocking end 301 of the unlocking button 3 is provided with a strip-shaped hole 303 for avoiding the headrest rod and an unlocking block 304 for engaging with the height adjustment slot of the headrest rod. By pressing the pressing end 302 of the unlock button 3 in the horizontal direction, the unlocking end 301 of the unlock button 3 overcomes the elasticity of the V-shaped retaining spring 4, causing the unlocking block 304 of the unlock button 3 to separate from the height adjustment slot of the headrest rod. After unlocking, the headrest rod can be height adjusted. When the pressing end 302 of the unlock button 3 is released, the V-shaped retaining spring 4 rebounds and drives the unlocking block 304 to engage in the height adjustment slot of the headrest rod. The bottom surface of the headrest guide cover 2 is provided with a limiting strip groove 202. The bottom of the unlock button 3 is provided with a limiting slider 305 corresponding to the position of the limiting strip groove 202. The limiting slider 305 of the unlock button 3 engages in the limiting strip groove 202. The limiting slider 305 is used to prevent the unlock button 3 from popping out of the headrest guide cover 2 due to excessive rebound force of the V-shaped retaining spring 4. The unlocking block 304 has an embedded groove inside for inserting one side of the V-shaped retaining spring 4.

[0019] Working principle: The headrest guide sleeve body 1 unlocks the headrest via the unlock button 3. A Y-axis force (horizontal direction) pushes the unlock button 3, which presses the V-shaped retaining spring 4, pushing the unlocking block 304 out of the headrest rod height adjustment slot, unlocking the headrest Z-axis limit and realizing the headrest height adjustment function. When the Y-axis force of the unlock button is released, the unlock button 3 is reset under the internal stress of the V-shaped retaining spring 4, locking the headrest rod and restricting the Z-axis movement of the headrest rod.

[0020] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
