[0038] In order to have a clearer understanding of the technical features, objectives and effects of the utility model, the specific implementation manners of the utility model will be described with reference to the drawings, wherein the same reference numerals in the drawings represent the same or similar components with the same function.

[0039] In this document, "schematic" means "serving as an example, instance or illustration", and any illustration or implementation described as "schematic" in this document should not be interpreted as a more preferred or more advantageous technical solution.

[0040] Figure 1 A sectional structure schematic view of a schematic implementation manner of the utility model. Figure 2 A sectional structure schematic view of a schematic implementation manner of the utility model. Figure 1 A partial structure schematic view of the utility model. Figure 1 A partial structure schematic view of the utility model. Figure 2As shown, the car's height-adjustable center armrest includes an armrest body 10, a pneumatic regulator 20, and four lifting mechanisms 30. The armrest body 10 has a cavity 11 to facilitate the installation of the pneumatic regulator 10 and the lifting mechanisms 30. The four lifting mechanisms 30 are symmetrically arranged in pairs on both sides of the cavity 11 within the armrest body 10 to provide multi-point support and enhance lifting stability.

[0041] In this illustrative embodiment, the air pressure regulator 20 is centrally located in the receiving cavity 11 and is simultaneously connected to the lifting mechanisms 30 on both sides via hoses to ensure that the air pressure on both sides changes synchronously when gas is filled or retracted, thereby achieving smooth lifting and lowering of the handrail body 10.

[0042] like Figure 1 As shown, each lifting mechanism 30 includes a push rod 32, an elastic reset member 34, and a first connecting member 36. The push rod 32 is fixedly connected to the handrail body 10. In this illustrative embodiment, the upper end of the push rod 32 is fixed to a preset hole inside the handrail body 10 by thread, ensuring that the push rod 32 is parallel to the vehicle height direction and ensuring the stability of lifting.

[0043] like Figure 2 As shown, the first connecting member 36 is movably sleeved on the push rod 32 along the vehicle height direction and abuts against the other end of the elastic reset member 34. The first connecting member 36 passes through the armrest body 10 and abuts against the vehicle's sub-dashboard. In this illustrative embodiment, the first connecting member 36 is cylindrical to stably support the armrest body 10. The first connecting member 36 has an air chamber 361. The push rod 32 is inserted into the air chamber 361 of the first connecting member 36, and one end of the push rod 32 inserted into the air chamber 361 is provided with a sealing piston, which is clearance-fitted with the inner wall of the air chamber 361 to ensure stable lifting and lowering.

[0044] The outer peripheral wall of the first connector 36 extends circumferentially to form an annular support platform 362. An elastic reset member 34 (e.g., a rubber sleeve or a coil spring) is fitted over the push rod 32, with one end abutting against the armrest body 10 and the other end abutting against the support platform 362, thereby providing a reset force. The support platform 362 protrudes towards the vehicle's sub-dashboard, forming two symmetrically arranged guide pillars 364 (in other illustrative embodiments, three or more may be provided, evenly distributed along the circumference of the first connector).

[0045] Each guide post 364 passes through the armrest body 10 and abuts against the vehicle's sub-dashboard, thereby ensuring the stability of the support for the first connecting member 36. A spring 38 is sleeved on the guide post 364, and its two ends are fixed to the support platform 362 and the armrest body 10 respectively, to assist in elastic reset. At the same time, the combination design of the elastic reset member 34 and the spring 38 can effectively reduce vibration and improve comfort.

[0046] likeFigure 2 As shown, each lifting mechanism 30 further comprises a tubular second connecting member 39. The second connecting member 39 is fixedly connected to the handrail body 10, and is sleeved on the first connecting member 36 and abuts against the support platform 362, thereby limiting the lateral displacement of the first connecting member 36 and the elastic return member 34, and ensuring the lifting stability of the lifting mechanism 30. In other exemplary embodiments, the push rod 32, the second connecting member 39 and the handrail body 10 can be integrally formed, so as to improve the overall strength and stability of the central handrail, and facilitate assembly.

[0047] Figure 3 As shown in the cross-sectional structural schematic diagram of the raised state of the automobile liftable central handrail. Figure 1 As shown in the cross-sectional structural schematic diagram of the raised state of the automobile liftable central handrail. Figure 4 As shown in the cross-sectional structural schematic diagram of the raised state of the automobile liftable central handrail. Figure 1 As shown in the cross-sectional structural schematic diagram of the raised state of the automobile liftable central handrail. Figure 1 , Figure 3 and Figure 4 As shown, the air pressure regulator 20 is in communication with the air chamber 361 of the first connecting member 36 through a hose. When a user triggers a lifting instruction through an in-vehicle control button, the air pressure regulator 20 charges or recovers gas into the air chamber 361 according to the instruction. When the air pressure regulator 20 charges gas, the air pressure in the air chamber 361 increases, pushing the push rod 32 to displace upward along the automobile height direction, so that the elastic return member 34 is stretched and the spring 38 is compressed, driving the handrail body 10 to rise; when the air pressure regulator 20 recovers gas, the air pressure in the air chamber 361 decreases, and the restoring force of the elastic return member 34 and the spring 38 drives the push rod 32 to displace downward along the automobile height direction, so that the handrail body 10 descends to the initial position.

[0048] Figure 5 As shown in the cross-sectional structural schematic diagram of the raised state of the automobile liftable central handrail. Figure 5 As shown, the handrail body 10 is connected to an automobile center console (not shown in the figure) through the hinge assembly 40. The hinge assembly 40 comprises a sliding rail 42, a sliding block 44 and a hinge body 46. The sliding rail 42 is fixedly connected to the side surface of the handrail body 10. The sliding rail 42 is provided with a sliding groove 421, and the inclination angle of the sliding groove 421 is consistent with the lifting path of the handrail body 10. The sliding block 44 is embedded in the sliding groove 421 and can slide along the sliding groove.

[0049] The hinge body 46 comprises a rotating part 461 and a fixed part 463. In the present exemplary embodiment, the fixed part 463 is fixedly connected to the automobile center console through a bolt. The rotating part 461 is V-shaped, one end of the rotating part 461 of the hinge body 46 is connected to the fixed part 463 through a pin shaft, and the other end is fixed to the sliding block 44 through a bolt. When the handrail body 10 is lifted, the sliding block 44 slides along the sliding groove 421, driving the rotating part 461 to rotate around the fixed part 463, so as to ensure that the handrail is lifted smoothly and without jamming.
