Description

Technical Field

[0001] This utility model belongs to the field of automotive seat armrest technology, specifically a telescopic armrest mechanism for automotive door panels. Background Technology

[0002] The patent number CN 206231257U discloses a utility model patent entitled "Universal Telescopic Armrest for Flip-Top Armrest Box in Car Center Console". Although the armrest can accommodate the arm placement of passengers of different weights, it does not meet the needs of passenger elbow comfort when adjusting the seat back for rest on the door armrest. The internal mechanism of the armrest is a double guide rail design, which is also unreasonable from the perspective of space and economy for the door armrest, as it occupies too much space. Therefore, it is not suitable for the comfort needs of passengers on the door armrest, and is only suitable for the armrest box in the middle position between the left and right passengers.

[0003] Patent number CN 215042305U discloses a utility model patent entitled "A Retractable Car Seat Armrest," which is a manually pull-out type armrest. However, due to the height difference and the fact that it is mechanically retractable and requires manual extension, it lacks a premium feel for the front left and right side doors and fails to meet the comfort needs of passengers. The manual pull-out design of the armrest's internal mechanism is also unreasonable from a space and comfort perspective for a car door armrest. It occupies too much space and is therefore unsuitable for passenger comfort on car door armrests; it is only suitable for the armrest box in the middle position between the left and right passengers. Utility Model Content

[0004] To address the above problems, this utility model provides a telescopic armrest mechanism for automobile doors.

[0005] The technical solution of this utility model is as follows: a telescopic armrest mechanism for an automobile door panel includes a first rotating arm, a second rotating arm, multiple rotating shafts, an armrest, a motor, and a lower trim panel frame. The motor is fixed on the lower trim panel frame. One side of the first rotating arm is fixed to the output shaft of the motor. The rotation of the motor can drive the first rotating arm to rotate. The other side of the first rotating arm is hinged to the armrest. One side of the second rotating arm is hinged to the armrest, and the other side of the second rotating arm is hinged to the lower trim panel frame.

[0006] Furthermore, the motor is fixed to the lower trim panel frame with screws.

[0007] Furthermore, a through hole is provided on one side of the first rotating arm, and parallel and concentric through holes are provided on the other side of the first rotating arm.

[0008] Furthermore, the other side of the first rotating arm is hinged to the handrail via a pivot.

[0009] Furthermore, the other side of the first rotating arm is hinged to the handrail via a pivot.

[0010] Furthermore, parallel and concentric through holes are provided on both sides of the second rotating arm.

[0011] Furthermore, one side of the second rotating arm is hinged to the armrest via a pivot, and the other side of the second rotating arm is hinged to the lower trim panel frame via a pivot.

[0012] Furthermore, it also includes a switch panel trim, which is snapped or screwed onto the lower trim frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] The telescopic armrest mechanism allows for forward and backward adjustment to accommodate different arm positions during rest. This mechanism ensures that even when a passenger adjusts the seat significantly backward, their arms can still rest comfortably on the armrest, increasing the armrest's travel range and enhancing passenger comfort. The switch-mounted decorative panel, snapped onto the lower trim frame, prevents the internal structure from being exposed after movement, thus improving both safety and aesthetics. This invention also significantly reduces noise and lowers costs. Attached Figure Description

[0027] It should be noted that in the description of this utility model, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," and "joining" should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; a connection can be a mechanical connection or an electrical connection; a joint can be a direct connection or an indirect connection through an intermediate medium, and 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.

[0029] This utility model consists of (a lead screw, a lead screw connecting plate, a handrail, a motor, a lower trim panel frame, and a switch panel trim mechanism). The lead screw is fixed to the lower trim panel frame, the handrail is installed together with the lead screw via the lead screw connecting plate, and the motor is fixed to the lead screw, giving this utility model the function of front and rear adjustment (after movement, the internal structure is covered by the switch panel trim that is snapped onto the lower trim panel frame).

[0030] A telescopic armrest mechanism for a car door panel includes a first rotating arm 1, a second rotating arm 2, a pivot 3, an armrest 4, a motor 5, a lower trim panel frame 6, and a switch panel trim panel 7.

[0031] The motor 5 is fixed to the lower trim panel frame 6 by two screws.
