Technical Field
[0001] The invention relates to the field of vehicles, and in particular to a double-opening armrest rotation opening and adjusting device. Background Art
[0002] The sub-dashboard armrest is usually installed above the center console inside the vehicle. Its main function is to provide elbow support for the front driver and passenger, thereby increasing the comfort during driving or riding. As consumers' requirements for the in-car environment experience increase, the sub-dashboard armrest not only needs to meet the basic support function, but also needs to have a good user experience perception. In the existing design scheme, there are some technical problems waiting to be solved. For example, some double-opening armrests have different opening speeds, one fast and one slow, resulting in a poor user experience. Summary of the invention
[0003] To this end, it is necessary to provide a double-opening armrest rotating opening adjustment device to solve the problem that the existing double-opening armrests have different speed performance when opening, resulting in poor user experience.
[0004] To achieve the above-mentioned purpose, the present embodiment provides a double-opening armrest rotation opening and adjustment device, including a mounting base, two rotating shafts, a damper, an unlocking assembly, two pre-tightening stop rings and two friction gaskets, the two rotating shafts are arranged on the mounting base, the damper is arranged on the rotating shaft, the armrest rotates following the rotation of the rotating shaft, the unlocking assembly is arranged on the mounting base, and is used to unlock the two armrests locked on the mounting base, one rotating shaft corresponds to one pre-tightening stop ring and one friction gasket, the pre-tightening stop ring is interference fit with the outer wall of the rotating shaft, and the friction gasket is sleeved on the outer wall of the pre-tightening stop ring and is arranged on the mounting base.
[0005] Furthermore, the pre-tightening stop ring has a unilateral interference of 0.15 mm with the rotating shaft.
[0006] Furthermore, the inner end of the pre-tightening stop ring close to the rotating shaft is a conical surface inclined to the axial direction of the rotating shaft, and the conical surface has fractures evenly arrayed along the peripheral direction, and the fractures extend to the end of the conical surface.
[0007] Furthermore, the pre-tightening stop ring and the friction gasket are both located on one end of the rotating shaft extending to the outside of the mounting base, and the pre-tightening stop ring is located on the outside of the friction gasket.
[0008] Furthermore, the friction gasket is in a convex shape, and the mounting base is provided with a slot hole for accommodating the friction gasket.
[0009] Furthermore, the gap between the rotating shaft and the mounting base is 0.2 mm.
[0010] Furthermore, a limiting structure is provided at one end of the rotating shaft located in the mounting base, and the limiting structure abuts against a limiting portion inside the mounting base.
[0011] To achieve the above-mentioned purpose, the present embodiment further provides a vehicle, comprising a double-opening armrest rotation opening adjustment device as described in any one of the above items.
[0012] Different from the prior art, the above technical solution has the following beneficial effects:
[0013] When the armrest needs to be opened, the user applies force to rotate the armrest around the rotation axis. At this time, due to the interference fit between the preload stop ring and the rotation axis, a certain preload force will be generated. This preload force will be transmitted to the friction gasket, causing friction between the friction gasket and the mounting base, thereby affecting the rotation speed of the armrest. By adjusting the position of the preload stop ring, the pressure on the friction gasket can be changed, and then the size of the friction force can be adjusted, and finally the rotation speed of the armrest can be controlled.

[0038] See also Figures 1 to 7The present embodiment provides a double-opening armrest rotation opening adjustment device, comprising a mounting base 1, two rotating shafts 2 arranged on the mounting base 1 and a damper arranged on the rotating shaft 2, the armrest 3 rotates following the rotation of the rotating shaft 2, the double-opening armrest rotation opening adjustment device also includes an unlocking assembly 6, the unlocking assembly 6 is arranged on the mounting base 1, and is used to unlock or lock the two armrests 3 on the mounting base 1, the double-opening armrest rotation opening adjustment device also includes two pre-tightening stop rings 4 and two friction gaskets 5, one rotating shaft 2 corresponds to one pre-tightening stop ring 4 and one friction gasket 5, the pre-tightening stop ring 4 is interference fit with the outer wall of the rotating shaft 2, and the friction gasket 5 is sleeved on the outer wall of the pre-tightening stop ring 4 and is arranged on the mounting base 1.
[0039] It should be noted that the preload stop ring 4 and the rotating shaft 2 have an interference fit. Interference fit means that in mechanical assembly, when one part (such as a shaft) is inserted into another part (such as a hole), there is a certain amount of interference between the two parts, so that after the assembly is completed, the two parts can form a close contact. There is zero clearance between the rotating shaft 2 and the friction pad 5. When the rotating shaft 2 rotates, the friction pad 5 will also rotate with it, thereby ensuring the consistency of the movement of the two. The gap between the rotating shaft 2 and the base sheet can be 0.2mm, ensuring that the rotating shaft 2 can operate normally without hindrance during use.
[0040] When the armrest 3 needs to be opened, the user applies force to rotate the armrest 3 around the rotating shaft 2. At this time, due to the interference fit between the preload stop ring 4 and the rotating shaft 2, a certain preload force will be generated. This preload force will be transmitted to the friction pad 5, so that friction force will be generated between the friction pad 5 and the mounting base 1, thereby affecting the rotation speed of the armrest 3. By adjusting the position of the preload stop ring 4, the pressure on the friction pad 5 can be changed, and then the magnitude of the friction force can be adjusted, and finally the rotation speed of the armrest 3 can be controlled.
[0041] See also Figure 7 In this embodiment, the pre-tightening stop ring 4 and the rotating shaft 2 have a unilateral interference of 0.15 mm. Such a design ensures that there is a suitable contact pressure between the pre-tightening stop ring 4 and the rotating shaft 2.
[0042] See also Figure 3 and Figure 7 In this embodiment, the inner end of the pre-tightening stop ring 4 close to the rotating shaft 2 is inclined to the axial direction of the rotating shaft 2 on the conical surface 41, and the conical surface 41 has fractures 42 evenly arrayed along the peripheral direction, and the fractures 42 extend to the end of the conical surface 41.
[0043] See also Figure 3 , Figure 4 and Figure 5In this embodiment, the preload stop ring 4 and the friction gasket 5 are both located on the end of the rotating shaft 2 extending to the outside of the mounting base 1, and the preload stop ring 4 is located on the outside of the friction gasket 5. This design allows the user to more easily approach and adjust the position of the preload stop ring 4, which is convenient for operation.
[0044] See also Figure 7 In this embodiment, the friction pad 5 is in a convex shape, and the mounting base 1 is provided with a slot 11 for accommodating the friction pad 5. Specifically, the narrower part of the convex shape is located in the slot 11, and the wider part is located outside the slot 11. In this way, the friction pad 5 can stably contact the mounting base 1 during the rotation process, and at the same time, the friction between the friction pad 5 and the mounting base 1 can be controlled by adjusting the pre-tightening stop ring 4, thereby realizing accurate control of the opening speed of the armrest 3.
[0045] See also Figure 8 In this embodiment, a limiting structure 21 is provided at one end of the rotating shaft 2 located in the mounting base 1, and the limiting structure 21 abuts against the limiting portion 12 inside the mounting base 1, so that the armrest 3 can rotate together with the rotating shaft 2 when rotating.
[0046] In this embodiment, the unlocking assembly 6 can be designed as a button-type structure, and the button is located on the side or top of the mounting base 1, which is convenient for the user to operate. A locking pin is connected under the button, and when the button is pressed, the locking pin will retract to release the lock on the rotating shaft 2. The unlocking assembly 6 can also be designed as a lever-type structure, and the lever is connected to the locking pin through a connecting rod. When the user pulls the lever, the connecting rod drives the locking pin to retract to achieve unlocking.
[0047] This embodiment also provides a vehicle, including the double-opening armrest rotation opening adjustment device as described in any one of the above embodiments, the structure is as follows: Figures 1 to 8 As shown. Select a vehicle suitable for installing the double-opening armrest rotation opening adjustment device, such as a sedan, SUV or other types of passenger cars. Select a mounting base 1 suitable for the vehicle's auxiliary dashboard, which is fixed in the vehicle body and is used to carry the entire adjustment device. Set two rotating shafts 2, which are respectively connected to the two ends of the armrest 3, allowing the armrest 3 to rotate along the axis.
[0048] The present application aims at the disadvantage that the opening time of the double-opening armrests of the auxiliary instrument of the existing vehicle models is inconsistent, and provides an adjustment device. The device adds a pre-tightening stop ring 4 and a friction pad 5 on the outer side of the rotating shaft 2 of the armrest 3. The friction between the friction pad 5 and the armrest 3 is controlled by the pre-tightening stop ring 4, and the opening speed of the armrest 3 is indirectly controlled. The pre-tightening stop ring 4 has an interference fit with the rotating shaft 2, and the interference amount is 0.15mm on one side. The friction between the friction pad 5 and the armrest 3 can be adjusted steplessly and progressively, and the consistency of the opening time of the double-opening armrests can be achieved. The adjustment device can simplify the influencing factors of the opening of the armrest 3 (such as the spring force, friction, weight, and damping force tolerance) into the influence of friction, reducing the difficulty of adjusting the armrest 3.
[0049] It should be noted that, although the above embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, changes and modifications made to the embodiments described herein, or equivalent structures or equivalent process changes made using the contents of the present invention specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present invention.
