[0002] With improved living standards and changing lifestyles, automobile consumption is becoming increasingly popular. According to surveys, the seats are the first thing most consumers see when they open the car door when purchasing a vehicle. Therefore, this initial impression of the seats' exterior quality directly influences consumers' judgment of the vehicle's overall quality. An increasing number of rear seats now feature armrests, which, when opened, provide both storage space and hand comfort for rear passengers.
[0003] Chinese patent publication number CN215752064U discloses an adjustable seat armrest. According to the height of the user, a power component drives a lifting component to drive the first armrest to adjust the height, and then the adjustment component is used to adjust the length of the first armrest, so that the height and length of the seat armrest can be adjusted according to the user's body shape. When encountering bumps, the vibration damping element can reduce the collision between the arm and the first armrest, thereby improving the comfort of use.
[0004] The above-mentioned armrest controls the operation of the motor so that the motor drives the transmission rod to rotate. At this time, the threaded sleeve pushes the first armrest up under the action of the thread, thereby completing the adjustment of the first armrest. Since the connecting sleeve is slidingly connected to the outer wall of the square rod, when pressure is applied to the first armrest, one side of the first armrest will push the connecting sleeve to move through the fourth connecting rod, and the stability of the first armrest cannot be guaranteed. Therefore, there are certain limitations. Utility Model Content

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a seat armrest height adjustment mechanism, comprising a support plate 1, a top plate 2 and a buffer pad 3, the top plate 2 is arranged above the support plate 1, the buffer pad 3 is fixedly connected to the top of the top plate 2, an adjustment component 4 is provided on the top of the support plate 1, and an auxiliary component 5 is provided on the outer wall of the top plate 2.
[0022] The adjusting assembly 4 includes a threaded rod 401, a rotating plate 402, a sleeve 403, a square rod 404 and a lifting rod 405. The threaded rod 401 is arranged above the support plate 1, and the rotating plate 402 is fixedly connected to the outer wall of the threaded rod 401. The sleeve 403 is sleeved above the support plate 1. The threaded rod 401 passes through the sleeve 403 and extends to the outside of the sleeve 403. The thread on the outer wall of the threaded rod 401 is adapted to the inner wall of the sleeve 403. The threaded rod 401 can be rotated to make the sleeve 403 move in the threaded position. The lifting rod 405 is fixedly connected to the outer wall of the sleeve 403, and the lifting rod 405 is arranged on the outside of the square rod 404. The two ends of the lifting rod 405 are respectively equipped with movable parts. The movable part at the bottom end of the lifting rod 405 is connected to the top of the square rod 404, and the movable part at the top end of the lifting rod 405 is connected to the bottom of the top plate 2. The lifting rod 405 can be adjusted in angle by the movable part and push the top plate 2 to move.
[0023] By setting the sleeve 403 and the lifting rod 405, the rotating plate 402 is rotated, and the threaded rod 401 rotates. At this time, the sleeve 403 will move under the action of the thread, and drive the square rod 404 to move outside the threaded rod 401. When the square rod 404 moves, it will push the top plate 2 to adjust the height through the lifting rod 405. The operation is simple and convenient. Moreover, since the sleeve 403 is threadedly connected to the threaded rod 401, when the threaded rod 401 is not rotated, the top plate 2 will remain stable under the action of the lifting rod 405.
[0024] The auxiliary component 5 includes an extension plate 501, a square plate 502, a clamping rod 503 and a magnetic block 504. The extension plate 501 is installed on the outer wall of the top plate 2. One side of the extension plate 501 passes through the top plate 2 and extends to the interior of the top plate 2. The outer wall of the extension plate 501 is slidably connected to the inner wall of the top plate 2, and the position of the extension plate 501 can be adjusted by sliding. The square plate 502 is fixedly connected to the outer wall of the top plate 2, and the clamping rod 503 is installed on the outer wall of the top plate 2. The clamping rod 503 passes through the square plate 502 and extends to the interior of the extension plate 501. The outer walls of the clamping rod 503 are slidably connected to the inner walls of the square plate 502 and the inner walls of the extension plate 501 respectively, and the installation of the clamping rod 503 can be completed by sliding. The clamping rod 503 is distributed on both sides of the outer wall of the extension plate 501, and the magnetic blocks 504 are fixedly connected to the inner wall of the clamping rod 503. The magnetic blocks 504 are magnetically connected to each other, and the clamping rod 503 can be limited by the magnetic block 504.
[0025] By setting up the extension plate 501 and the clamping rod 503, the extension plate 501 can be moved in a sliding manner to expand the armrest, which is convenient for the operator to use. At the same time, by moving the clamping rod 503, the clamping rod 503 passes through the square plate 502 and extends to the inside of the extension plate 501, which can limit the extension plate 501 and ensure the stability of the extension plate 501 during use.
[0026] When in use, by rotating the rotating plate 402, the rotating plate 402 drives the threaded rod 401 to rotate. At this time, the sleeve 403 will drive the square rod 404 to move under the action of the outer wall thread of the threaded rod 401. Since the top of the square rod 404 is rotatably connected to the bottom end of the lifting rod 405 through a movable part, and the bottom of the top plate 2 is rotatably connected to the top end of the lifting rod 405 through a movable part, when the square rod 404 moves, the lifting rod 405 will be driven to rotate at the bottom of the top plate 2 through the movable part. When the lifting rod 405 rotates, it will push the top plate 2 to lift, thereby adjusting the height of the top plate 2.
