[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] like Figures 1 to 4 As shown, this embodiment provides an elastic support structure, including:

[0035] Assembly mechanism 1, serving as the basic installation platform for the entire elastic support structure, is installed on the side of the car seat;

[0036] Mounting component 2 is mounted on assembly mechanism 1, and a guide component 3 is provided at the end of mounting component 2;

[0037] Two movable parts 4 are slidably installed in the inner cavity of the guide 3, and springs 5 ​​are respectively installed at the far ends of the two movable parts 4 to provide elastic restoring force;

[0038] Adjustment mechanism 6 is installed on guide member 3. Adjustment mechanism 6 is located in the middle of two moving members 4. Adjustment mechanism 6 is used to drive the relative position of the two moving members 4 and guide member 3.

[0039] The fixing part 7 is rotatably mounted on the assembly mechanism 1, and the fixing part 7 is connected to the springs 5 ​​on the two moving parts 4 respectively, serving as the end execution structure of the elastic support for installing the car armrest;

[0040] In this embodiment, the assembly mechanism 1 serves as a basic installation platform mounted on the side of the car seat, providing a stable installation foundation for the entire structure. The mounting component 2 cooperates with the guide component 3 to provide a precise sliding track for the two moving components 4, ensuring that the moving components 4 move smoothly and without deviation. The springs 5 ​​mounted at the far ends of the two moving components 4 can provide reliable elastic restoring force, effectively buffering the impact on the arm when the car is bumpy, thus improving riding comfort. The adjustment mechanism 6 is located in the middle of the two moving components 4, which can precisely drive the relative position of the moving components 4 and the guide component 3 to change the compression stiffness of the spring 5 to adapt to the needs of passengers with different requirements. The fixing component 7, which is rotatably mounted on the assembly mechanism 1, is connected to the spring 5 and serves as the end-acting structure for mounting the car armrest. It can achieve adaptive buffering of the armrest through the elastic action of the spring 5, significantly improving the comfort, flexibility and stability of the car armrest.

[0041] As a preferred embodiment of the above technical solution, such as Figures 2 to 3 As shown, the adjustment mechanism 6 includes:

[0042] The threaded rod 61 is connected to the threaded through hole of the guide 3, and the threaded rod 61 is provided with an adjustment hole;

[0043] Elliptical cylinder 62 is coaxially mounted on threaded rod 61, and elliptical cylinder 62 is connected to two moving parts 4.

[0044] At least one nut 63 is installed on the threaded rod 61. The nut 63 is used to lock the relative rotation between the threaded rod 61 and the guide member 3.

[0045] In this embodiment, the elliptical cylinder 62, coaxially mounted on the threaded rod 61, changes its engagement position with the two moving parts 4 as the threaded rod 61 rotates, thereby precisely adjusting the relative position of the moving parts 4 and the guide part 3. The stiffness of the spring 5 is adjusted by changing the degree of compression, meeting the personalized needs of different passengers for arm support strength. The threaded through hole of the threaded rod 61 and the guide part 3 engages, utilizing the characteristics of the thread to pre-lock the position of the elliptical cylinder 62. The nut 63 is installed on the threaded rod 61, which can lock the relative rotation of the threaded rod 61 and the guide part 3, preventing the threaded rod 61 from rotating due to vibration during vehicle operation, ensuring the stability of the spring 5's compression stiffness setting value, avoiding changes in the elastic support effect, and ensuring that the car armrest is always in an ideal buffering and support state.

[0046] As a preferred embodiment of the above technical solution, such as Figure 1 As shown, the fastener 7 has a slot, and a sealing cap 8 is installed at the slot;

[0047] In this embodiment, the slot provides a channel for the adjustment operation of the adjustment mechanism 6, making it convenient for the operator to operate the adjustment mechanism 6 through the slot of the fixing part 7, thereby realizing convenient adjustment of the compression hardness of the spring 5. The sealing cover 8 installed at the slot can seal the slot after adjustment, effectively preventing dust, moisture and other impurities from entering the interior of the fixing part 7.

[0048] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, the assembly mechanism 1 includes:

[0049] Assembly 11 is installed at the back end of the seat, and an adjusting component 12 is slidably installed in the inner groove of assembly 11;

[0050] The support shaft 13 is rotatably mounted on the adjusting member 12, and the mounting member 2 is fixedly mounted on the support shaft 13, while the fixing member 7 is rotatably mounted on the support shaft 13.

[0051] The drive mechanism 14 is mounted on the assembly 11. The drive mechanism 14 is used to adjust the working height of the fixing part 7 driven by the adjusting part 12.

[0052] A limiting member 15 is provided on the support shaft 13, and the limiting member 15 is slidably connected to the inner groove of the adjusting member 12. The limiting member 15 is used to limit the rotation range of the support shaft 13.

[0053] In this embodiment, the assembly 11 is installed at the end of the seat back, providing a stable support base for the entire structure. The adjustable component 12, which is slidably installed inside, cooperates with the drive mechanism 14 to precisely adjust the working height of the fixing component 7, so that the car armrest can adapt to the usage needs of passengers of different heights. The drive mechanism 14 drives the fixing component 7 to rise and fall through the adjustable component 12 to meet the personalized needs of arm support height under different sitting postures. The limiting component 15 set on the support shaft 13 is slidably connected to the inner groove of the adjustable component 12, precisely limiting the rotation range of the support shaft 13. The assembly mechanism 1 achieves flexible adjustment in two dimensions: height and angle, and improves reliability through limiting protection, thus comprehensively optimizing the user experience of the car armrest.

[0054] As a preferred embodiment of the above technical solution, such as Figure 2 As shown, a damping pad 16 is provided at the rotatable connection between the support shaft 13 and the fixing member 7;

[0055] In this embodiment, the damping pad 16 can increase the rotational resistance between the support shaft 13 and the fixing member 7, preventing the handrail from swaying due to excessive rotation or inertia, and providing passengers with more stable arm support. During the car's operation, the damping pad 16 can buffer the vibration of the fixing member 7 caused by bumps, reduce the vibration transmitted to the handrail, and further enhance comfort. In addition, the damping pad 16 can also effectively suppress the noise generated during rotation, creating a quiet riding environment.

[0056] As a preferred embodiment of the above technical solution, such as Figures 1 to 2 As shown, the drive mechanism 14 includes:

[0057] The drive shaft 13a is rotatably mounted on the assembly 11. The drive shaft 13a is provided with an external thread, and the external thread is fitted with the threaded inner hole of the adjusting component 12.

[0058] Adjusting cap 13b is coaxially mounted on drive shaft 13a;

[0059] In this embodiment, the drive shaft 13a is rotatably mounted on the assembly 11, and its external thread engages with the threaded inner hole of the adjusting member 12. Utilizing the high precision and stability of the threaded transmission, the rotational motion of the drive shaft 13a is converted into the linear lifting motion of the adjusting member 12, thereby precisely driving the fixing member 7 and the connected car armrest to adjust its height. The adjusting cap 13b, coaxially mounted on the drive shaft 13a, provides a convenient point of force application for the operator. By rotating the adjusting cap 13b, the drive shaft 13a can be easily driven to rotate, realizing stepless adjustment of the armrest height. This meets the personalized needs of different passengers for arm support height in different sitting postures, ensuring the stability and reliability of the car armrest height, and effectively improving the practicality of the elastic support structure and the user's operating experience.

[0060] The elastic support structure of this invention can be used in various types of car handrails;

[0061] Compared with existing support structures, the elastic support structure of this invention can precisely adapt to the height, sitting posture and personalized support needs of different passengers in terms of adjustment flexibility, and has an effective cushioning and shock absorption design in terms of comfort and stability, improving the arm support experience when riding.
