Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive seat technology, and relates to headrests, specifically a manual four-way headrest with adjustable headrest buttons. Background Technology
[0002] Four-way headrests, compared to ordinary headrests, offer additional fore-and-aft adjustment, allowing for simultaneous up-and-down and fore-and-aft adjustments. This makes it easy to adjust the headrest to a more comfortable position, catering to the different needs of people of varying heights, and is now widely used. Existing four-way headrests are divided into electric and manual types. Electric four-way headrests are more expensive, and the motor can generate noise and vibration during adjustment, affecting comfort. Manual four-way headrests are cheaper, so most car seats typically use manual four-way headrests. However, existing manual four-way headrests suffer from complex structures, large size, and inconvenient adjustment. Summary of the Invention
[0003] In view of the above-mentioned technical problems and shortcomings, the purpose of this utility model is to provide a manual four-way headrest with adjustable headrest buttons. This headrest can realize four-way multi-position adjustment functions in the up and down and forward and backward directions, ensuring passenger safety while also taking into account the passenger's needs for different positions of the seat headrest, providing passengers with a better comfortable riding experience. This structure is reasonably simple in design and easy to operate.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A manual four-way headrest with adjustable headrest buttons includes a housing frame, a front housing fixing structure, front and rear guide rails, a button body, upper and lower locking springs, front and rear locking springs, front and rear slide rails with built-in locking grooves, upper and lower adjustment guide sleeves, a horizontal push rod, a push rod return spring, front and rear adjustment guide sleeves, and a headrest rod.
[0006] The shell frame has an upper and lower adjustment guide sleeve located near both sides along the Z direction. The upper and lower adjustment guide sleeve is equipped with upper and lower locking springs for fixing the headrest rod. The shell frame has a front and rear guide rail and a front and rear adjustment guide sleeve located along the X direction. The front and rear guide rail can slide back and forth relative to the shell frame. The front and rear adjustment guide sleeve is equipped with a front and rear slide rail with a locking groove. The front and rear slide rail can slide back and forth relative to the front and rear adjustment guide sleeve. The front and rear guide rails and the front and rear slide rails are fixedly connected to the front shell fixing structure.
[0007] The button body is disposed on one side of the housing frame and is used to drive the horizontal push rod to move laterally; the horizontal push rod is disposed inside the housing frame, with its end in contact with the button body, and it can move laterally relative to the housing frame; a push rod return spring is provided between the horizontal push rod and the housing frame; the push rod return spring is used to push the horizontal push rod to return to its original position.
[0008] One end of the upper and lower locking spring is mounted on the upper and lower adjusting guide sleeve, and the other end is set in the mounting hole of the horizontal push rod. The upper and lower locking spring is driven away from the locking groove of the headrest rod by the horizontal push rod to realize the unlocking in the upper and lower directions.
[0009] One end of the front and rear locking springs is mounted on the front and rear adjusting guide sleeves, and the other end is set in the mounting hole of the transverse push rod. The transverse push rod drives the front and rear locking springs away from the locking grooves of the front and rear slide rails, thereby achieving unlocking in the front and rear directions.
[0010] As a preferred embodiment of this utility model, there are two front and rear guide rails, which are arranged in a triangular pattern with the front and rear slide rails. The two front and rear guide rails are close to the upper end of the shell frame. The front shell fixing structure has an assembly part on the side facing the front and rear guide rails. The ends of the front and rear guide rails and the front and rear slide rails are installed in the assembly part of the front shell fixing structure and fixed by the front and rear slide rail fixing pins.
[0011] As a preferred embodiment of this utility model, the housing frame is provided with a guide part at the position where the front and rear guide rails are installed. The guide part is a cylindrical structure. The end of the guide part is machined with a positioning groove near both sides. The end of the front and rear guide rails is provided with a front and rear slide rail positioning pin along the Y direction. After the front and rear guide rails slide forward and backward, the two ends of the front and rear slide rail positioning pins are set in the positioning grooves and continue to slide forward along the positioning grooves.
[0012] As a preferred embodiment of this utility model, the front and rear sides of the upper and lower adjusting guide sleeve are both machined with upper and lower limiting grooves, and the upper and lower sliding rail fixing pins are installed on the headrest rod, with both ends set in the upper and lower limiting grooves.
[0013] As a preferred embodiment of this utility model, the upper and lower sides of the front and rear adjusting guide sleeves are both machined with front and rear limiting grooves, and the front and rear slide rail fixing pins are installed on the front and rear slide rails, with both ends set in the front and rear limiting grooves.
[0014] As a preferred embodiment of this utility model, the button body includes a button, a button reset spring, and a button cover; wherein, the button cover is engaged with the housing frame, the button is disposed inside the button cover and can move laterally relative to the button cover, and the button reset spring is disposed between the button and the button cover for pushing the button to reset.
[0015] Advantages and beneficial effects of this utility model: The headrest mechanism provided by this utility model allows for multi-directional and multi-level adjustment when the button on the side of the headrest is pressed. The button slides along the Y-axis inside the button cover, pushing the horizontal push rod. Simultaneously, the horizontal push rod moves along the Y-axis, driving the upper and lower locking springs and the front and rear locking springs. Driving the front and rear locking springs unlocks the front and rear slide rails, enabling the front shell of the headrest to move forward and backward. Driving the upper and lower locking springs unlocks the headrest rod, enabling the headrest to move up and down. That is, pressing the button unlocks both the up and down and forward and backward directions simultaneously. When the button pressure is released, the adjustment mechanism returns to the locked state under the action of internal stress. This headrest can achieve multi-directional and multi-level adjustment and has advantages such as simple structure, good stability, and convenient operation. Attached Figure Description
