AI Technical Summary
Existing car hinges are prone to wear due to high friction during opening and closing of doors, and are subject to greater pressure on the door, resulting in a reduced service life.
A high-strength auto hinge with automatic lubrication is designed. By setting the oil storage layer and oil outlet hole in the left hinge, and installing balls on the oil outlet hole. When the ball rotates, the lubricating oil in the oil storage layer is automatically lubricated. Reduce friction while setting reinforcement ribs on the hinge to increase strength.
Automatic lubrication technology reduces the friction of the hinge, extends the service life, and improves the strength of the hinge through reinforcement ribs, enhancing the stability of door opening and closing.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile hinges and relates to a hinge, in particular to a high-strength automobile hinge. Background Art
[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow relative rotation between them. In the automotive field, hinges are mostly used on car doors.
[0003] During the opening and closing process of the car door, the hinge rotates around the connecting shaft inside it. Due to the heavy weight of the door, when the hinge rotates, the friction between the connecting shaft and the hinge is relatively large, which can easily lead to serious wear on the connecting shaft, making the door easy to shake. In addition, when the door is opened and closed, the door will put a lot of pressure on the hinge, making the hinge easy to be damaged and reducing its service life. Summary of the invention
[0004] The utility model aims to provide an automatic lubricating high-strength automobile hinge in view of the above problems existing in the prior art.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a high-strength automobile hinge, including a hinge body, characterized in that the hinge body is composed of a left hinge, a right hinge and a rotating shaft, an oil storage layer is opened in the left hinge, a plurality of oil outlet holes are opened on the left hinge, the oil outlet holes are connected to the oil storage layer, a plurality of balls are arranged on the oil outlet holes, the left hinge and the right hinge are both provided with a reinforcing rib one, the left hinge and the right hinge are both provided with a reinforcing rib two, the reinforcing rib two is arranged in an x-shape and is connected to the reinforcing rib one.
[0006] In the above-mentioned high-strength automobile hinge, an oil injection pipeline is provided on the left hinge, the oil injection pipeline is connected to the oil storage layer, and a plug is provided at the oil injection pipeline.
[0007] In the above-mentioned high-strength automobile hinge, the left hinge is provided with a first mounting portion, and the right hinge is provided with a second mounting portion.
[0008] Compared with the prior art, the utility model provides a plurality of balls which can convert the sliding friction between the left hinge and the rotating shaft into rolling friction to reduce friction, and the left hinge is provided with an oil storage layer. When the balls roll, the lubricant in the oil storage layer will be driven to automatically lubricate, thereby reducing friction and increasing service life. The reinforcing ribs provided increase the strength of the hinge and increase service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0013] like Figure 1 As shown, the high-strength automobile hinge includes a hinge body 1, which is composed of a left hinge 2, a right hinge 3 and a rotating shaft 4. An oil reservoir 5 is provided in the left hinge 2, and a plurality of oil outlet holes 6 are provided on the left hinge 2. The oil outlet holes 6 are connected to the oil reservoir 5. A plurality of balls 7 are provided on the plurality of oil outlet holes 6. The balls 7 can convert the sliding friction between the left hinge 2 and the rotating shaft 4 into rolling friction to reduce friction. The left hinge 2 is provided with an oil reservoir 5. When the balls 7 roll, the lubricant in the oil reservoir 5 is driven to automatically lubricate, thereby reducing friction and increasing service life. A reinforcing rib 12 is provided on both the left hinge 2 and the right hinge 3. A reinforcing rib 2 13 is provided on both the left hinge 2 and the right hinge 3. The reinforcing rib 2 13 is provided in an x-shape and is connected to the reinforcing rib 12 to increase the overall strength of the hinge.
[0014] To further elaborate, an oil injection pipeline 8 is provided on the left hinge 2 , the oil injection pipeline 8 is connected to the oil reservoir 5 , and a plug 9 is provided at the oil injection pipeline 8 .
[0015] To be more specific, the left hinge 2 is provided with a mounting portion 10 , and the right hinge 3 is provided with a mounting portion 2 11 .
[0016] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0017] Although the present invention uses more terms such as hinge body 1, left hinge 2, right hinge 3, rotating shaft 4, oil reservoir 5, oil outlet 6, ball 7, oil injection pipe 8, plug 9, mounting part 10, mounting part 2 11, reinforcing rib 1 12, reinforcing rib 2 13, etc., it does not exclude the possibility of using other terms. The use of these terms is only for the purpose of more conveniently describing and explaining the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
