[0033] Example 1

[0034] This embodiment provides a door hinge structure, such as Figure 1-7 As shown, the door hinge structure includes a hinge body 1, a rotating shaft sleeve 2 and a bushing 3, the hinge body 1 has a mounting hole 11, the outer peripheral surface of the bushing 3 has a U-shaped groove 31, the bushing 3 is fixed in the mounting hole 11, and the U-shaped groove 31 can be clamped at the edge of the mounting hole 11, and the rotating shaft sleeve 2 is arranged in the bushing 3.

[0035] The door hinge structure is used to connect the vehicle body and the door, so that the door can be rotated relative to the vehicle body to open or close. In the conventional technology, the door and the vehicle body are generally connected by a hinge structure, but the conventional hinge structure is prone to problems such as stagnation, looseness, and friction noise. These problems are caused by the poor fit between the bushing and the mounting hole on the hinge body. This embodiment solves the above problems by optimizing the fit between the bushing and the hinge body.

[0036] Specifically, the hinge body 1 is fixed on the vehicle door. The embodiment does not limit the shape of the hinge body 1, as long as it can drive the vehicle door. Of course, in order to make the hinge body 1 better match with the vehicle door, the hinge body 1 preferably has two sides, which correspond to the two sides of the vehicle door respectively. This matching mode can make the opening and closing of the vehicle door more stable.

[0037] The general outline of the bushing 3 is a circular ring structure with a certain thickness. A circle of grooves is provided on the outer peripheral surface of the bushing 3. The groove has a groove bottom and two groove walls. In the axial section of the bushing 3, the groove is U-shaped, that is, the above-mentioned U-shaped groove 31. The rotating sleeve 2 includes two cylinders with different diameters. Of course, the two cylinders are integrally formed. Here, they are separated only for the convenience of description. It is assumed that the cylinder with a smaller diameter is the first cylinder and the cylinder with a larger diameter is the second cylinder.

[0038] The hinge body 1 is provided with a mounting hole 11. Since the hinge body 1 has a certain thickness, the edge of the mounting hole 11 also has a certain thickness. When the bushing 3 is set in the mounting hole 11, the first cylinder of the rotating sleeve 2 is inserted into the bushing 3, and the second cylinder has a larger diameter and is located outside the bushing 3. In the specific use process, the hinge body 1 can rotate around the rotating sleeve 2. Since the hinge body 1 is set on the vehicle door and the rotating sleeve 2 is set on the vehicle body, the vehicle door also rotates relative to the vehicle body during the rotation of the hinge body 1, thereby realizing the opening and closing of the vehicle door. During the rotation process, the bushing 3 can protect the mounting hole 11 and the rotating sleeve 2 to avoid damage caused by long-term friction between the two.

[0039] In this embodiment, during the cooperation between the bushing 3 and the hinge body 1, the U-shaped groove 31 on the outer peripheral surface of the bushing 3 can just be stuck at the edge of the mounting hole 11, and wrap the edge of the mounting hole 11, thereby ensuring the reliability of the connection between the bushing 3 and the hinge body 1, and avoiding the technical problems of the traditional door hinge structure that cannot completely wrap the edge of the mounting hole, resulting in the bushing being easily stuck, loose, and causing abnormal friction noise.

[0040] In a specific embodiment, the bushing 3 is a steel-based bushing, and the surface of the steel-based bushing has a lubricating coating. That is, the bushing provided in this embodiment is a steel-based bushing, and the surface of the steel-based bushing has a lubricating coating. The setting of the lubricating coating enables the bushing 3 to have a lubricating function in addition to the rotation holding function during the opening or closing process of the door, so that after long-term use, the rotating sleeve 2 will not be loosened or adsorbed with foreign matter such as dust, causing friction noise.

[0041] In a specific embodiment, the lubricating coating is polytetrafluoroethylene.

[0042] Polytetrafluoroethylene, commonly known as "the king of plastics", is a polymer compound formed by the polymerization of tetrafluoroethylene, and has excellent chemical stability, corrosion resistance, sealing, high lubricity and non-stickiness, electrical insulation and good anti-aging resistance. This embodiment utilizes the high lubricity and non-stickiness of polytetrafluoroethylene.

[0043] The polytetrafluoroethylene coating has high lubricity and is the lowest friction coefficient among solid materials; the surface tension is the lowest among solid materials and it does not adhere to any substance. Compared with the pure polytetrafluoroethylene bushing, the bushing 3 provided in this embodiment has a polytetrafluoroethylene coating added to the surface of the steel-based bushing, which has higher strength and can make the bushing 3 have a lubrication function in addition to the rotation retention function during the opening or closing of the door. After long-term use, it will not cause the looseness of the rotating structure and the friction noise caused by the adsorption of foreign matter such as dust, thereby improving the user experience.

[0044] In a specific embodiment, in order to ensure the rotation stability of the hinge body 1, the rotating sleeve 2 and the bushing 3 are coaxially arranged.

[0045] In a specific embodiment, the rotating sleeve 2 and the bushing 3 are clearance-fitted.

[0046] The rotating sleeve 2 and the bushing 3 are concentric circles, and there is a gap between them after they are matched, which can ensure that the rotating sleeve 2 can rotate normally in the bushing 3 without causing the rotating sleeve 2 to shake in the bushing 3, and play a role in keeping the door position stable and rotating. When the door is opened or closed, the bushing 3 and the hinge body 1 rotate with the rotating sleeve 2 as the axis, and the lubricating coating on the outer surface of the bushing 3 provides lubrication to prevent friction and noise, and relies on the hinge body 1 to keep the door stable.

[0047] In a specific embodiment, in order to realize the connection between the rotating sleeve 2 and the vehicle body, as shown in FIG. Figure 5 As shown, the door hinge structure further includes a connecting component 4, one end of which is arranged on the rotating shaft sleeve 2, and the other end of which is connected to the vehicle body.

[0048] In addition, from Figure 7 It can be seen that there is a notch on the bushing 3. This is because after the bushing 3 is formed, it is difficult to complete the assembly with the mounting hole 11. Therefore, during assembly, the unformed bushing 3, which may be a sheet-shaped material or a material with a small curvature, is first placed in the mounting hole 11, and then a fold is formed at the mounting hole 11 to form a U-shaped groove 31 that matches the edge of the mounting hole 11. During the process of forming the fold, if the material happens to be a closed circle, the whole process will be more difficult. Therefore, the generally formed bushing 3 has a notch, and the notch is for better forming the U-shaped groove 31.

[0049] In a specific embodiment, the connecting assembly 4 includes a bolt 41, the shank end of the bolt 41 passes through the rotating sleeve 2, and the head end of the bolt 41 is located outside the rotating sleeve 2. Figure 6 It can be seen from the figure that the interior of the rotating sleeve 2 is a hollow structure, and the hollow space is used to set the bolts.

[0050] In a specific embodiment, the connection assembly 4 further includes a flat washer 42 , which is sleeved on the bolt 41 and located between the screw head end and the end of the rotating sleeve 2 .

[0051] In this embodiment, a flat washer 42 is sleeved on the bolt 41 and is located between the screw head end and the end of the rotating sleeve 2, so as to reduce the friction between the end of the rotating sleeve 2 and the screw head end, prevent the rotating sleeve 2 and the bolt 41 from loosening, and disperse the pressure generated during the rotation of the hinge body 1.

[0052] In a specific embodiment, in order to further prevent the rotating sleeve 2 and the bolt 41 from loosening, the connecting assembly 4 further includes a spring washer 43, which is sleeved on the bolt 41 and located between the flat washer 42 and the screw head end.

[0053] The door hinge structure provided in this embodiment overcomes the problem in the prior art that the door hinge structure suffers from structural strength damage and abnormal friction noise after long-term use. This embodiment adopts a bushing with a U-shaped groove, and replaces the bushing material with a combination of a steel-based bushing and polytetrafluoroethylene, so that the hinge structure can maintain its structural stability and reduce friction after long-term use, thereby eliminating abnormal noise caused by looseness or interference and improving product performance and quality.

[0054] Example 2

[0055] This embodiment provides a vehicle, which includes a body, a door and the door hinge structure described in Example 1, wherein the hinge body 1 is arranged on the door, the rotating shaft sleeve 2 is located on the body, and the hinge body 1 rotates relative to the rotating shaft sleeve 2 so that the door rotates relative to the body.

[0056] The vehicle provided in this embodiment can be a bridge vehicle or a truck, etc., and the corresponding vehicle doors can be vehicle doors on seats or cargo box doors.

[0057] The vehicle provided in this embodiment adopts the door hinge structure in Embodiment 1, thereby improving the performance and quality of the entire vehicle and thus improving user satisfaction.

[0058] In summary, it is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous technical features can be freely combined and superimposed.

[0059] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form.
