Description

Technical Field

[0001] The utility model relates to the field of vehicles, in particular to a double-opening armrest rotation opening and adjusting device. Background Art

[0002] The sub-instrument panel armrest is usually installed above the central console inside the vehicle. Its main function is to provide elbow support for the front-row driver and passengers, thereby increasing the comfort during driving or riding. With the improvement of consumers' requirements for the in-vehicle environment experience, the sub-instrument panel armrest not only needs to meet the basic support function but also needs to have a good user experience perception. In the existing design solutions, there are some technical problems to be solved. For example, the opening speeds of some double-opening armrests are different, one fast and one slow, resulting in a poor user experience. Content of the Utility Model

[0003] Therefore, it is necessary to provide a double-opening armrest rotation opening and adjusting device to solve the problem that the opening speeds of the existing double-opening armrests are different, resulting in a poor user experience.

[0004] To achieve the above object, the present embodiment provides a double-opening armrest rotation opening and adjusting device, which includes an installation base, two rotating shafts provided on the installation base, and dampers provided on the rotating shafts. The armrest rotates following the rotation of the rotating shafts. The device further includes two pre-tightening stop rings and two friction washers. One rotating shaft corresponds to one pre-tightening stop ring and one friction washer. The pre-tightening stop ring is in interference fit with the outer wall of the rotating shaft, and the friction washer is sleeved on the outer wall of the pre-tightening stop ring and is provided on the installation base.

[0005] Further, the unilateral interference between the pre-tightening stop ring and the rotating shaft is 0.15 mm.

[0006] Further, 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. The conical surface is evenly arrayed with fractures along the outer peripheral direction, and the fractures extend to the end of the conical surface.

[0007] Further, both the pre-tightening stop ring and the friction washer are located at one end of the rotating shaft extending out of the installation base, and the pre-tightening stop ring is located outside the friction washer.

[0008] Further, the friction washer is convex-shaped, and the installation base is provided with a slot for accommodating the friction washer.

[0009] Further, the gap between the rotating shaft and the installation base is 0.2 mm.

[0010] Furthermore, one end of the rotating shaft located inside the mounting base is provided with a limiting structure, and the limiting structure abuts against the limiting part inside the mounting base.

[0011] To achieve the above object, this embodiment also provides a vehicle, including the double-opening armrest rotation opening and adjustment device as described in any one of the above embodiments.

[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 a force to make the armrest rotate around the rotating shaft. At this time, due to the interference fit between the pre-tightening stop ring and the rotating shaft, a certain pre-tightening force will be generated. This pre-tightening force will be transmitted to the friction gasket, causing a frictional force between the friction gasket and the mounting base, thereby affecting the rotation speed of the armrest. By adjusting the position of the pre-tightening stop ring, the pressure received by the friction gasket can be changed, and then the magnitude of the frictional force can be adjusted, and finally the rotation speed of the armrest can be controlled.

[0038] Please refer to Figures 1 to 7, this embodiment provides a double-opening armrest rotation and opening adjustment device, which includes an installation base 1, two rotating shafts 2 provided on the installation base 1, and dampers provided on the rotating shafts 2. The armrest 3 rotates following the rotation of the rotating shaft 2. The double-opening armrest rotation and opening adjustment device further 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 in 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 provided on the installation base 1.

[0039] It should be noted that the pre-tightening stop ring 4 is in interference fit with the rotating shaft 2. 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 interference amount between the two, so that after the assembly is completed, a tight contact can be formed between the two parts. There is zero clearance between the rotating shaft 2 and the friction gasket 5. When the rotating shaft 2 rotates, the friction gasket 5 will also rotate accordingly, thus ensuring the consistency of their movements. The clearance between the rotating shaft 2 and the base plate can be 0.2 mm to ensure that the rotating shaft 2 can operate normally without obstruction during use.

[0040] When the armrest 3 needs to be opened, the user applies a force to make the armrest 3 rotate around the rotating shaft 2. At this time, due to the interference fit between the pre-tightening stop ring 4 and the rotating shaft 2, a certain pre-tightening force will be generated. This pre-tightening force will be transmitted to the friction gasket 5, causing a frictional force between the friction gasket 5 and the installation base 1, thereby affecting the rotation speed of the armrest 3. By adjusting the position of the pre-tightening stop ring 4, the pressure received by the friction gasket 5 can be changed, thereby adjusting the magnitude of the frictional force and finally controlling the rotation speed of the armrest 3.

[0041] Please refer to Figure 7 , in this embodiment, the unilateral interference between the pre-tightening stop ring 4 and the rotating shaft 2 is 0.15 mm. Such a design ensures a suitable contact pressure between the pre-tightening stop ring 4 and the rotating shaft 2.

[0042] Please refer to 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 conical surface 41 of the rotating shaft 2. The conical surface 41 is evenly arranged with notches 42 along the outer circumference direction, and the notches 42 extend to the end of the conical surface 41.

[0043] Please refer to Figure 3 , Figure 4 and Figure 5 , in this embodiment, both the pre-tightening stop ring 4 and the friction gasket 5 are located at one end of the rotating shaft 2 extending outside the installation base 1. The pre-tightening stop ring 4 is located outside the friction gasket 5. This design enables the user to more easily access and adjust the position of the pre-tightening stop ring 4, facilitating operation.

[0044] Please refer to Figure 7 In this embodiment, the friction gasket 5 is convex-shaped, and the mounting base 1 is provided with a slot hole 11 for accommodating the friction gasket 5. Specifically, the narrower part of the convex shape is located in the slot hole 11, and the wider part is located outside the slot hole 11. In this way, the friction gasket 5 can stably contact the mounting base 1 during rotation. At the same time, by adjusting the pre-tightening stop ring 4, the frictional force between the friction gasket 5 and the mounting base 1 can be controlled, so as to achieve precise control of the opening speed of the armrest 3.

[0045] Please refer to Figure 8 In this embodiment, one end of the rotating shaft 2 located inside the mounting base 1 is provided with a limiting structure 21, and the limiting structure 21 abuts against the limiting part 12 inside the mounting base 1, so that the armrest 3 can rotate together with the rotating shaft 2 when rotating.

[0046] Please refer to Figure 1 and Figure 2 In this embodiment, the double-opening armrest rotation opening adjustment device further 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 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 for easy operation by the user. A locking pin is connected below the button. When the button is pressed, the locking pin will retract to release the locking of the rotating shaft 2. The unlocking assembly 6 can also be designed as a lever-type structure. 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 described in any of the above embodiments, and the structure is as Figures 1 to 8 shown. Select a vehicle suitable for installing the double-opening armrest rotation opening adjustment device, such as a sedan, an SUV or other types of passenger vehicles. Select a mounting base 1 suitable for the vehicle's sub-instrument panel. The base is fixed inside the vehicle and is used to carry the entire adjustment device. Set two rotating shafts 2, which are respectively connected to both ends of the armrest 3, allowing the armrest 3 to rotate along the axis.

[0048] In view of the disadvantage that the opening times of the double-opening armrests of the existing vehicle models are inconsistent, the present application provides an adjustment device. An additional pre-tightening stop ring 4 and a friction gasket 5 are added outside the rotating shaft 2 of the armrest 3. The pre-tightening stop ring 4 is used to control the frictional force between the friction gasket 5 and the armrest 3, indirectly controlling the opening speed of the armrest 3. The pre-tightening stop ring 4 has an interference fit with the rotating shaft 2, with a unilateral interference amount of 0.15 mm, and can steplessly and progressively adjust the frictional force between the friction gasket 5 and the armrest 3, enabling the consistency of the opening times of the double-opening armrests. This adjustment device simplifies the influencing factors (such as spring force magnitude, frictional force, weight, damping force tolerance) for opening the armrest 3 into frictional force influence, reducing the difficulty of adjusting the armrest 3.

[0049] It should be noted that although the above-mentioned embodiments have been described in this text, the patent protection scope of the present utility model is not limited thereby. Therefore, based on the innovative concept of the present utility model, any changes and modifications made to the embodiments described in this text, or equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present utility model.
