Description

Technical Field

[0001] This utility model relates to the field of vehicle accessory technology, and in particular to a door hinge assembly and a vehicle using the assembly. Background Technology

[0002] Door hinges are used to connect car doors to the car body and enable the door to rotate around the body along a fixed trajectory to open and close the door. Existing door hinges are integral stamped, forged, or cast parts made of all-metal materials, and are relatively heavy. Utility Model Content

[0003] This utility model proposes a door hinge assembly and a vehicle using the assembly.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A door hinge assembly includes a body component, which is U-shaped and has a weight-reducing groove in the middle. Fixed posts are fixedly installed on the inner walls of both sides of the body component. A pivot is rotatably installed between the two fixed posts. A fixed sleeve is fitted over the pivot. The fixed sleeve is fixedly installed to one end of the door component. The door component is arc-shaped. A connecting plate is fixedly installed at the other end of the door component. Two connecting holes are opened at both ends of the connecting plate.

[0006] A further preferred embodiment of this utility model is as follows: mounting plates are fixedly installed at both ends of the opening of the body part, and each mounting plate has two mounting holes.

[0007] A further preferred embodiment of this utility model is that the thickness of the end of the door component connected to the fixed sleeve is less than the thickness of the end of the door component connected to the connecting plate.

[0008] A further preferred embodiment of this utility model is provided: a weight-reducing groove is provided on one side of the middle part of the connecting plate.

[0009] A further preferred embodiment of this utility model is: a weight-reducing groove is provided in the curved part of the door component.

[0010] The present invention has the following advantages:

[0011] 1. The body parts, connecting plates and door parts of this utility model are respectively provided with weight reduction groove one, weight reduction groove two and weight reduction groove three, which can better ensure the lightweighting of the door hinge assembly and meet production requirements.

[0012] 2. The body parts, mounting plates, fixing sleeves, door parts, and connecting plates of this utility model are all integral forgings, which can avoid welding or casting defects, are easy to manufacture, and enable the front door hinge assembly to have better mechanical properties (strength, plasticity, hardness, impact toughness, and fatigue strength) and a longer service life.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1:

[0020] according to Figure 1-4 The car door hinge assembly shown includes a body part 1, which is U-shaped. A weight reduction groove 6 is provided in the middle of the body part 1. Fixed posts are fixedly installed on the inner walls of both sides of the body part 1. A rotating shaft 10 is rotatably installed between the two fixed posts. A fixing sleeve 7 is provided on the outer sleeve of the rotating shaft 10. The fixing sleeve 7 is fixedly installed together with one end of the car door part 3. The car door part 3 is arc-shaped. A connecting plate 4 is fixedly installed at the other end of the car door part 3. Two connecting holes 5 are provided at both ends of the connecting plate 4.

[0021] Mounting plates 2 are fixedly installed at both ends of the opening of the body part 1, and each mounting plate 2 has two mounting holes 11.

[0022] The thickness of the end where the door component 3 is connected to the fixing sleeve 7 is less than the thickness of the end where the door component 3 is connected to the connecting plate 4. This arrangement can reduce weight without affecting the strength of the device.

[0023] A weight reduction groove 9 is provided on one side of the middle part of the connecting plate 4. This design can better ensure the lightweighting of the door hinge assembly and meet production requirements.

[0024] The door component 3 has a weight reduction groove 8 on its curved part. This design can better ensure the lightweighting of the door hinge assembly and meet production requirements.

[0025] Example 2:

[0026] A vehicle that uses the door hinge assembly mentioned in Example 1.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
