Description

Technical Field

[0001] This utility model relates to the field of automotive seat armrest technology, specifically an adjustable armrest mechanism for automotive seats. Background Technology

[0002] Adjustable armrests in car seats are a crucial component of modern automotive design. Their primary function is to enhance passenger comfort and safety by adjusting the position and angle of the armrests. Passengers can adjust the armrests according to their needs to achieve optimal support and comfort, adapting to different seating postures and space requirements.

[0003] To facilitate passengers placing water cups and other daily necessities, some car seats have cup holders on the upper part of their armrests. However, existing adjustable armrest mechanisms in some car seats can only adjust the position and angle of the armrest as a whole. When the armrest is adjusted to the position and angle required by the passenger, the cup holder on the armrest is often tilted and cannot stably hold the water cup. Therefore, an adjustable armrest mechanism for car seats is proposed to address the above problem. Summary of the Invention

A pair of locking blocks slidably connected to the mounting shell are provided on the lower side of the pressing block. A transmission block is provided on the upper side of each locking block. A compression spring is fixedly connected to the slot on the opposite side of each of the two locking blocks. The end of the compression spring away from the locking block is fixedly connected to the inner wall of the mounting shell.

[0008] Preferably, the positioning sleeve is composed of a rectangular plate with an opening in the middle and a round tube fixedly connected to the opening. The front end face of the positioning sleeve and the end face of the damping sleeve are in contact. The damping sleeve passes through the rear side wall and the front side wall of the mounting shell. The damping sleeve and the mounting shell are rotatably connected. The adjusting toothed ring is located inside the mounting shell.

[0009] Preferably, the pressing block is symmetrical from left to right, and the pair of locking blocks and transmission blocks are symmetrically distributed.

[0026] Please see Figure 1-8 This utility model provides a technical solution:

[0027] An adjustable armrest mechanism for a car seat includes a mounting column assembly 1, a locking assembly 2, an armrest assembly 3, and a cup holder assembly 4. The mounting column assembly 1 includes a main mounting column 11, a positioning column 12 fixedly connected to the front end of the main mounting column 11, a damping sleeve 13 rotatably connected to the outer side of the positioning column 12, and an adjusting gear ring 14 fixedly connected to the rear half of the damping sleeve 13. The armrest assembly 3 is located on the front side of the mounting column assembly 1. The armrest assembly 3 includes an armrest body 31 fixedly connected to the front half of the damping sleeve 13, and a locking armrest 14 rotatably connected to the front end of the positioning column 12 at the left side of the inner part of the armrest body 31. A rotating shaft 32 is provided, and a first transmission gear ring 33 is fixedly connected to the outer side of the first rotating shaft 32. A second rotating shaft 34 is rotatably connected to the inner right side of the armrest body 31. A second transmission gear ring 35 is fixedly connected to the outer side of the second rotating shaft 34. A tensioned transmission belt 36 is sleeved on the outer side of the first transmission gear ring 33 and the second transmission gear ring 35. A cup holder assembly 4 is provided on the right side of the armrest assembly 3. The cup holder assembly 4 includes a cup holder body 41 located on the right side of the armrest body 31. A mounting base 42 is fixedly connected to the left side of the cup holder body 41. The mounting base 42 is fixedly connected to the front and rear ends of the second rotating shaft 34.

[0028] A locking assembly 2 is provided on the outer side of the mounting column assembly 1. The locking assembly 2 includes a positioning sleeve 21 fixedly connected to the main mounting column 11. A mounting shell 22 is fixedly connected to the front side of the positioning sleeve 21. A pressing block 23 is slidably connected to the upper opening of the mounting shell 22. A pair of locking blocks 24 slidably connected to the mounting shell 22 are provided on the lower side of the pressing block 23. A transmission block 25 is provided on the upper side of each locking block 24. A compression spring 26 is fixedly connected to the slot on the opposite side of each locking block 24. The end of the compression spring 26 away from the locking block 24 is fixedly connected to the inner wall of the mounting shell 22. The second transmission can be activated by the transmission action of the transmission belt 36. The toothed ring 35 rotates at the same speed but in the opposite direction as the first transmission toothed ring 33, thus causing the cup holder body 41 and the mounting base 42 to rotate synchronously with the armrest body 31. The positioning sleeve 21 consists of a rectangular plate with an opening in the middle and a round tube fixedly connected to the opening. The front end face of the positioning sleeve 21 fits against the end face of the damping sleeve 13. The damping sleeve 13 passes through the rear and front side walls of the mounting shell 22, and the damping sleeve 13 is rotatably connected to the mounting shell 22. The adjusting toothed ring 14 is located inside the mounting shell 22, and the adjusting toothed ring 14 can be limited by the locking block 24, thus preventing the armrest body 31 from rotating. The pressing block 23 is symmetrical from left to right, forming... The locking blocks 24 and transmission blocks 25 are symmetrically distributed. The two locking blocks 24 are located on the left and right sides of the adjusting gear ring 14, respectively. The opposing sides of the two locking blocks 24 are provided with engagement grooves that match the adjusting gear ring 14. The upper inclined end faces of the transmission blocks 25 are respectively attached to the lower inclined end faces of the pressing blocks 23. By moving the pressing blocks 23 downward, the two transmission blocks 25 can be moved away from each other, thereby moving the two locking blocks 24 away from each other. The armrest body 31 is a shell, and the outer side of the transmission belt 36 is attached to the inner side wall of the armrest body 31. The number of teeth, tooth height, tooth tip circle diameter, and tooth root circle of the first transmission gear ring 33 and the second transmission gear ring 35 are specified. All have the same diameter. The inner teeth of the transmission belt 36 match the first transmission gear ring 33 and the second transmission gear ring 35. During the rotation of the armrest body 31, the transmission belt 36 can be displaced through the first transmission gear ring 33, thereby driving the second transmission gear ring 35 to rotate. The front end face of the first rotating shaft 32 is aligned with the front end face of the armrest body 31, and the front and rear end faces of the second rotating shaft 34 are aligned with the front and rear end faces of the armrest body 31, respectively. The upper side of the cup holder body 41 is provided with a cup storage groove. The mounting base 42 is a "U" shaped base. The second rotating shaft 34 can drive the mounting base 42 to rotate synchronously, thereby causing the cup holder body 41 to rotate.

[0029] Workflow: Before use, install the main mounting column 11 in the appropriate position on the car seat and check that all components are intact. If intact, the device can be used normally. When the device is not affected by external force, the two sets of compression springs 26 are in a compressed state. The elasticity of the compression springs 26 can bring a pair of locking blocks 24 closer together. The pair of locking blocks 24 can limit the adjustment gear ring 14, so that the damping sleeve 13 cannot rotate, and thus the armrest body 31 cannot rotate. When using the device, the passenger can first sit on the seat and reach out to press the pressing block 23, so that the pressing block 23 is relative to the positioning sleeve plate. The fixed mounting shell 22 moves downward, causing the two transmission blocks 25 to move away from each other, the two locking blocks 24 to move away from each other, and the two sets of compression springs 26 to be further compressed. At this time, the locking block 24 releases its limit on the adjusting gear ring 14, and the passenger can hold the handrail body 31 and rotate it to the desired position and angle. The damping sleeve 13 on the outside of the positioning post 12 and the adjusting gear ring 14 will rotate together with the handrail body 31. After the handrail body 31 is adjusted, the passenger no longer presses the pressing block 23, and the paired locking blocks 24 can move closer to each other with the help of the elastic force of the compression springs 26. The locking blocks 24 can automatically adjust the position. Adjusting the gear ring 14 limits its movement, and simultaneously pushes the pressing block 23 upward through the paired transmission blocks 25. At this time, the adjusting gear ring 14 cannot rotate, so the damping sleeve 13 and the handrail body 31 also cannot rotate. The adjusted handrail body 31 can maintain a fixed position and angle. During the rotation of the handrail body 31, since the first rotating shaft 32 and the first transmission gear ring 33 cannot rotate relative to the main mounting post 11, while the handrail body 31 and the damping sleeve 13 can rotate, the handrail body 31 will rotate relative to the first rotating shaft 32 and the first transmission gear ring 33, causing the transmission belt 3... 6 can be displaced, and the transmission belt 36 can drive the second transmission gear ring 35 to rotate, thereby causing the second rotating shaft 34 to rotate relative to the armrest body 31. The second rotating shaft 34 can drive the mounting base 42 to rotate synchronously, thereby causing the cup holder body 41 to rotate. The direction of rotation of the second rotating shaft 34 is opposite to the direction of rotation of the armrest body 31, and the angle of rotation of the second rotating shaft 34 is the same as the angle of rotation of the armrest body 31. Therefore, when the passenger rotates the armrest body 31, the mounting base 42 and the cup holder body 41 can rotate synchronously, and the mounting base 42 and the cup holder body 41 always remain horizontally distributed.This device can displace the transmission block 25 by pressing the block 23, which in turn displaces the locking block 24, releasing the locking block 24 from limiting the adjusting gear ring 14. This allows the adjusting gear ring 14 and the damping sleeve 13 to rotate, thereby allowing the armrest body 31 to rotate and adjust. The compression spring 26 can automatically reset the locking block 24 and limit the adjusting gear ring 14 again. Furthermore, the device can use the transmission belt 36 to cause the second transmission gear ring 35 to rotate at the same speed but in the opposite direction to the first transmission gear ring 33, thus allowing the cup holder body 41 and the mounting base 42 to rotate synchronously with the armrest body 31. This device not only allows for position and angle adjustment of the armrest body 31 but also ensures that the cup holder body 41 and the mounting base 42 remain horizontal, guaranteeing stable placement of cups and other items.
