Description

TECHNICAL FIELD

[0001] The present scheme relates to the technical field of armrest box hinge, in particular to a hovering damping hinge structure. BACKGROUND

[0002] The armrest box is a commonly equipped accessory for vehicles at present, which is installed and fixed between two seats of the driver's cabin to provide a storage space, and a elbow rest is installed above the storage space, which serves as a cover plate of the storage space and also as an elbow support structure for the driver during driving.

[0003] The hinge structure of the armrest box is the key to the opening and hovering of the armrest box. The mainstream damping hovering armrest box is mainly realized by a damping sheet. When the armrest box needs to be opened after being locked, the optimal state is that the upper cover of the armrest box can be automatically opened at a certain angle to facilitate the opening operation. In the prior art, the mounting hole of the fixed support is generally circular and is sleeved on the rotating shaft body in order to pass through the bolt fixing position and is completely limited by the components on both sides. Once the bolt is loose or falls off, the fixed support will slip on the rotating shaft body when losing the limiting function, and the hinge structure will lose the damping effect.

[0004] Therefore, a hinge structure is needed to solve the problem of damping failure caused by the slippage of the fixed support. SUMMARY

[0005] To solve the above problems, the present scheme provides a hovering damping hinge structure to solve the problem of damping failure caused by the slippage of the fixed support.

[0006] To achieve the above purpose, the technical scheme adopted by the present scheme is as follows: a hovering damping hinge structure, comprising a fixed support, a rotating support and a damping component limited on the shaft body of a shaft pin, and being symmetrically arranged on both sides; the shaft pin shaft body is a four-section structure, wherein the gear set on both sides of the fixed support is flattened to present a smooth plane, and the first support mounting hole of the fixed support is a flat structure and is matched with the gear set of the shaft pin.

[0007] Further, the shaft pin comprises a nut, an annular groove set, a smooth rod body, a gear set and a thread set in sequence;

[0008] The damping component comprises a damping washer, a damping mounting sheet and a metal washer in sequence.

[0009] Further, the annular groove set is in contact with the damping washer at the outer periphery;

[0010] The smooth end between the annular groove set and the smooth rod body limits the damping mounting sheet;

[0011] The smooth rod body is in contact with the metal washer and the rotating support at the outer periphery;

[0012] The two sides of the thread group are flattened to present smooth planes, facilitating the passage of the fixing support and the contact of the outer periphery with the bolt.

[0013] Further, the damping assembly further comprises a first rivet and a second rivet.

[0014] Further, the first rivet fixes the damping washer and the damping mounting plate on the rotating support, and the second rivet fixes the damping mounting plate on the rotating support.

[0015] Further, one end of the metal washer is embedded in the rotating support, and the other end is attached to the fixing support.

[0016] Further, the first support mounting hole on the two sides of the fixing support has an arc surface structure on the upper and lower surfaces and is attached to the gear part of the gear group, and the two side surfaces have a rectangular structure and are attached to the flattened surfaces of the gear group.

[0017] Further, the fixing support further comprises a first protrusion and a second protrusion.

[0018] Further, the first protrusion is used for rigid connection, and the second protrusion is symmetrically arranged at the two ends of the fixing support and is used for limiting the maximum stroke of the moving support.

[0019] Further, the rotating support is a rotating end used for connecting the armrest box cover body and comprises a second support mounting hole, a first through hole and a second through hole.

[0020] In summary, the present scheme has the following advantages:

[0021] The shaft pin provided by the present scheme limits the damping assembly through different structural shapes on the upper side, ensures smooth rotation of the rotating support, increases the damping effect of other components, and has more friction and stability;

[0022] The combination of the fixing support and the gear group provided by the present scheme overcomes the slippage problem caused by the absence of limiting on both sides of the fixing hole in the prior art. When the bolt is loose, the position of the first support mounting hole and the gear group remains unchanged, the other side of the fixing support still attaches to the metal washer, the friction damping effect of the damping assembly does not disappear, and the slippage situation is avoided.

[0034] The present scheme will be further described below in combination with the drawings and examples:

[0035] Example 1:

[0036] A hovering damping hinge structure, as shown in Figures 1-6 , includes a fixed bracket 1 and a rotating bracket 2.

[0037] Referring to the drawings, Figures 1-5 the fixed bracket 1 is the fixed end of the hinge structure, and the fixed bracket 1 includes a first bracket mounting hole 11, a first protrusion 12 and a second protrusion 13. The first bracket mounting hole 11 is a flat structure with an arc surface structure on the upper and lower surfaces and a rectangular structure on the two side surfaces.

[0038] The first protrusion 12 is used for rigid connection, and the second protrusion 13 is symmetrically arranged at both ends of the fixed bracket 1 and is used for limiting the maximum stroke of the moving bracket.

[0039] The rotating bracket 2 is a rotating end used for connecting the handrail box cover body and includes a second bracket mounting hole 21, a first through hole 22 and a second through hole 23.

[0040] In the embodiment, the shaft pin 3 passes through the first bracket mounting hole 11 of the fixed bracket 1 and the second bracket mounting hole 21 of the rotating bracket 2, and is bilaterally symmetric, that is, the shaft pin 3 is the rotating shaft body of the rotating bracket 2 and the fixed bracket 1, and is bilaterally arranged, thereby ensuring the stability of the connection and rotating support.

[0041] Referring to the drawings Figure 1 、 2 , 5, 6, the end of the shaft pin 3 is a nut 31, and the rest of the shaft body is a four-section structure. The structure of the shaft pin 3 sequentially comprises the nut 31, an annular groove set 32, a smooth rod body 33, a gear set 34, and a thread set 35, and the two sides of the gear set 34 and the thread set 35 are flattened to present smooth planes.

[0042] The nut 31 plays a limiting role at one end of the shaft pin 3, and a damping assembly 4 is arranged on the shaft pin 3. The damping assembly 4 sequentially comprises a damping washer 41, a damping mounting plate 42, and a metal washer 43.

[0043] The annular groove set 32 is in contact with the damping washer 41 at the outer periphery, thereby playing a role in optimizing the damping value and improving the rotating feeling of the rotating bracket 2.

[0044] The damping washer 41 is composed of a plurality of damping pieces, and different damping effects can be achieved by increasing or decreasing the number of damping pieces, thereby realizing customization of different damping hinges.

[0045] The annular groove set 32 and the smooth rod body 33 further comprise a smooth end in the middle, the damping mounting plate 42 is limited at the outer periphery of the smooth end, a first rivet 401 passes through a third through hole 411 of the damping washer 41 and a fourth through hole 421 of the damping mounting plate 42, the first rivet 401 passes through the third through hole 411 and the fourth through hole 421, and is finally limited in the first through hole 22, thereby fixing the damping washer 41 and the damping mounting plate 42 on the rotating bracket 2. The damping mounting plate 42 further comprises a fifth through hole 422, a second rivet 402 passes through the fifth through hole 422 and the second through hole 23, and the damping mounting plate 42 is fixed on the rotating bracket 2.

[0046] The smooth rod body 33 is in contact with the metal washer 43 and the rotating bracket 2 at the outer periphery, and the structural characteristics of the smooth rod body 33 facilitate the rotation of the rotating bracket 2; one end of the metal washer 43 with a small diameter is embedded in the rotating bracket 2, and one end with a large diameter is close to the fixed bracket 1 and abuts against the first bracket mounting hole 11, thereby preventing the fixed bracket 1 and the rotating bracket 2 from overlapping to generate excessive friction force, and avoiding the rotating bracket 2 from being unable to rotate.

[0047] The gear set 34 is in contact with the fixed bracket 1 at the outer periphery, and the structural characteristics of the gear set 34 increase the friction force between the gear set 34 and the fixed bracket 1, thereby being more stable.

[0048] The gear set 34 is flattened on both sides, and the overall shape is a profile structure of the first bracket mounting hole 11, wherein the flattened surface matches the rectangular surface structure of the first bracket mounting hole 11, and the gear set 34 matches the arc surface structure. The structure of the gear set limits the fixed bracket 1.

[0049] The combination of the fixed bracket 1 and the gear set 34 provided in the present application flattens the shape of the first bracket mounting hole 11, and flattens the gear set 34 on both sides. The gear of the gear set 34 is clamped in the first bracket mounting hole, the two flattened surfaces of the gear set 34 match the first bracket mounting hole 11, and the slipping problem caused by the lack of limiting on both sides of the fixing hole in the prior art is overcome. That is, when the bolt 36 is loose, the position of the first bracket mounting hole 11 and the gear set remains unchanged, the other side of the fixed bracket 1 still matches the metal washer 43, and the friction damping effect of the damping assembly 4 does not disappear, avoiding the occurrence of slipping.

[0050] The threaded set 35 contacts the bolt 36 on the outer periphery, and the bolt 36 fastens the damping assembly 4, the fixed bracket 1 and the rotating bracket 2 on the shaft pin 3.

[0051] In summary, the shaft pin provided in the present application limits the damping assembly through different structural shapes on the top, ensures that the fixed bracket does not slip, and the rotating bracket rotates smoothly. At the same time, the damping effect of other components is increased, and the friction and stability are improved.

[0052] The combination of the fixed bracket and the gear set provided in the present application clamps the gear of the gear set in the first bracket mounting hole, and the two flattened surfaces of the gear set match the first bracket mounting hole, overcoming the slipping problem caused by the lack of limiting on both sides of the fixing hole in the prior art. When the bolt is loose, the position of the first bracket mounting hole and the gear set remains unchanged, the other side of the fixed bracket still matches the metal washer, and the friction damping effect of the damping assembly does not disappear, avoiding the occurrence of slipping.
