Technical Field

[0001] This utility model relates to the field of automotive armrest technology, specifically to an automotive armrest frame. Background Technology

[0002] A rear seat armrest is a device located in the middle of the rear seats of a car, providing arm support for passengers when they are seated in the back. For example, during long journeys, passengers can rest their arms on the armrest to reduce shoulder and arm fatigue and make the seating posture more comfortable and pleasant.

[0003] The aforementioned device lacks an adjustable armrest height, meaning that the height of the existing rear armrests in automobiles cannot be adjusted after vehicle production. Since passengers have different body shapes and heights, and their usage of the armrests also varies greatly, a single-height armrest cannot meet the needs of multiple groups of people. Based on the shortcomings of existing technology, this utility model designs an automobile armrest frame. Utility Model Content

[0022] Please see Figure 1-4 A car armrest frame includes an armrest body 1, a first movable groove 2 on the upper surface of the armrest body 1, an extension support mechanism 3 on the upper surface of the armrest body 1 to facilitate the extension of the usable height, a cushion 101 fixedly connected to the lower surface of the armrest body 1, a first rotating shaft 102 fixedly connected to both sides of the tail end of the armrest body 1, a traction belt 103 fixedly connected to the front end of the armrest body 1, and a storage groove 104 fixedly connected to the front end of the upper surface of the armrest body 1, with a cup groove 105 provided inside the storage groove 104.

[0023] Please see Figure 3-4 The extended support mechanism 3 includes a second movable groove 301, a second rotating shaft 302, a rotating ring 303, a support arm 304, and a support plate 306. Two second movable grooves 301 are formed on the upper surface of the handrail body 1. Four second rotating shafts 302 are fixedly connected inside the second movable grooves 301. The rotating ring 303 is rotatably connected to the second rotating shafts 302. The bottom end of the support arm 304 is set on the rotating ring 303. The second hinge block 305 is rotatably hinged to the top end of the support arm 304. The support plate 306 is fixedly connected to the upper surface of the support arm 304. The interior of the second movable groove 301 is provided with four sets of second rotating shafts 302, rotating rings 303, support arms 304 and second hinge blocks 305. The support arms 304 and second hinge blocks 305 are movably disposed inside the second movable groove 301. The support plate 306 is movably disposed on the upper surface of the handrail body 1. The front end of the second movable groove 301 is set with an inclined surface, and the support arm 304 contacts the inclined surface of the second movable groove 301 after it is unfolded.

[0024] By setting a second movable groove 301, a second rotating shaft 302, a rotating ring 303, and a support arm 304, the support arm 304 can be rotated and unfolded on the second rotating shaft 302 via the rotating ring 303 to adjust the height of the tray 306. The inclined surface of the second movable groove 301 provides support for the support arm 304 and the tray 306. By setting a second hinge block 305 and the tray 306, the second hinge block 305 can pull the top end of the support arm 304 to move when the tray 306 is pushed, so that the support arm 304 can be rotated and unfolded for support.

[0025] Please see Figure 3-4 The first movable groove 2 is rotatably connected to a first rotary joint 201. A traction spring 202 is fixedly connected to one side of the first rotary joint 201. A second rotary joint 203 is fixedly connected to the top of the traction spring 202. A hinge seat 204 is rotatably connected to the second rotary joint 203. The first movable groove 2 is opened between two second movable grooves 301. The hinge seat 204 is fixedly connected to the lower surface of the support plate 306. The traction spring 202, the second rotary joint 203 and the hinge seat 204 are arranged inside the first movable groove 2.

[0026] By setting a traction spring 202 and a hinge seat 204, a downward traction force is always provided to the front end of the tray 306, so that the tray 306 will not unfold when closed due to the downward traction force at the front end, and will not move backward and retract after the tray 306 is lifted and opened due to the downward traction force at the front end. By setting a first rotary joint 201 and a second rotary joint 203, the two ends of the traction spring 202 can be rotated and adjusted accordingly during the up, down, left and right movement and adjustment of the tray 306.

[0027] Working principle: When a car armrest frame is used, in the initial state, the cushion 101 and the first rotating shaft 102 are respectively set at the bottom and rear end of the armrest body 1. The upper surface of the armrest body 1 is provided with a storage groove 104 and a cup groove 105 to increase the functionality of the armrest body 1. The second rotating shaft 302 is installed in the second movable groove 301 opened on the upper surface of the armrest body 1. The rotating ring 303 rotatably connected to the second rotating shaft 302 is connected to the second hinge block 305 through the support arm 304. The second hinge block 305 is fixedly connected to the lower surface of the support plate 306 to adapt to different usage environments with the lifting and moving support plate 306.

[0028] When the height of the support plate 306 needs to be adjusted, after the armrest body 1 is rotated horizontally via the first pivot 102, the support plate 306 is pushed upwards towards the front end. This causes the support plate 306 to move the second hinge block 305 connected to it upwards towards the front end. The moving second hinge block 305 pulls the top of the hinged support arm 304 to rotate, and causes the bottom of the support arm 304 to rotate on the second pivot 302 and the rotating ring 303, slowly lifting the support plate 306 until the support arm 304 is aligned with the first pivot 102. After the inclined surface of the second movable groove 301 is released, it continues to support the pallet 306. During the movement of the pallet 306, the traction spring 202 is also pulled through the hinge seat 204. When the support arm 304 contacts the second movable groove 301 to support the pallet 306, the traction spring 202 can continuously provide forward traction force to the pallet 306 through the second rotary joint 203 and the hinge seat 204 to prevent the pallet 306 from moving backward and falling quickly. This device makes it easy to adjust the working height of the pallet 306.
