[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0025] Please see Figure 1-5 As shown, a left-right adjustable seat armrest structure includes an armrest consisting of an upper armrest housing 1, a lower armrest housing 2, and a lower armrest guide tube 8. The upper armrest housing 1 is connected to the lower armrest housing 2 by bolts. A slider 3 is provided inside the lower armrest housing 2, and the slider 3 is connected to the lower armrest guide tube 8 by bolts passing through the lower armrest housing 2. An adjustment switch button 7 is installed inside the lower armrest guide tube 8. A limit block 4 is installed on the top of the adjustment switch button 7, and the limit block 4 is located inside the lower armrest housing 2. A stop block 5 is sleeved on the surface of the adjustment switch button 7, and a return spring 6 is fixedly installed between the stop block 5 and the adjustment switch button 7.
[0026] Specifically, the bottom of the lower armrest housing 2 has a hole through which the stop block 5, return spring 6, and adjustment switch button 7 pass. The interior of the lower armrest housing 2 has a groove that matches the slider 3. The top of the adjustment switch button 7 has a mating groove, which is used to limit the stop block 4. The stop block 4 is connected to the lower armrest housing 2 by a countersunk bolt. The upper armrest housing 1 is made of a skin-friendly, non-slip material, and one end of the upper armrest housing 1 is inclined.
[0027] Specifically, there are two sliders 2, which are mounted on the lower guide tube 8 of the handrail. The bottom of the adjustment switch button 7 is arc-shaped and protrudes from the lower guide tube 8 of the handrail. The limiting block 4 is located at the top of the lower housing 2 of the handrail, and the stop block 5 is located at the bottom of the lower housing 2 of the handrail.

The leftmost and rightmost positions are limited by the groove of the lower housing 2 of the handrail, which reduces the space occupied and optimizes the structure.
[0029] It should be noted that: by creating grooves in the lower housing 2 of the handrail, wobbling during use is reduced. Additionally, a mating groove is provided at the point where the limit block 4 engages with the switch button to prevent the handrail from rotating after installation.
[0030] The design of this application achieves the purpose of left and right adjustable handrails, allowing users to adjust the handrails to a suitable position according to different body types, improving both comfort and convenience. Furthermore, the lower housing 2 of the handrail is fixed to the wiring harness using a snap-fit method, making the snap-fit structure an integral part of the lower housing 2, resulting in a simple structure and convenient disassembly and maintenance. The adjustment switch button 7 is installed to the lower housing 2 using countersunk screws, ensuring a simple structure and good stability for left and right handrail adjustment.
[0031] Working principle: The handrail moves the limit block 4 upward by pressing the adjustment switch button 7. After the limit block 4 is completely disengaged from the limit groove of the lower housing 2 of the handrail, the left and right adjustment of the handrail is achieved by sliding the slider 3 left and right. Finally, under the action of the return spring 6, the limit block 4 moves downward to the corresponding groove, thereby locking. The leftmost and rightmost positions are limited by the groove of the lower housing 2 of the handrail.
