Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a car front cover mounting hinge. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the car. There are many types of automotive parts. As people's living standards improve, people's consumption of cars is also increasing, and the market for automotive parts is becoming larger and larger. In recent years, automotive parts manufacturers have also been developing rapidly. There are many types of automotive parts, one of which is the hinge used to connect the front cover of a car.

[0003] In the prior art, utility model patent CN212773939U provides a car front hood hinge assembly, including a body connecting piece and a front hood connecting piece. A mounting plate is fixedly installed on the right side of the body connecting piece, and a slot is provided on the front side of the front hood connecting piece. This car front hood hinge assembly, by setting a limiting rod, changes the structure of traditional hinges. When the hinge needs to be replaced, it is not necessary to disassemble all components; simply rotating a knob drives a screw to rotate, which in turn moves the limiting rod downwards. When the limiting rod disengages from the connecting shaft, rotating the rear limiting plate moves it backwards until it disengages from the threaded connection with the connecting shaft. At this point, the connecting shaft can be pulled forward for replacement. The entire disassembly process involves only rotation, significantly reducing maintenance time and improving maintenance efficiency. Furthermore, since only the connecting shaft needs to be replaced, materials are saved, achieving the effect of saving maintenance costs.

[0004] The replacement of the connecting shaft in this car front hood hinge assembly requires rotating a knob and a limiting plate, while simultaneously using a limiting rod inserted into the connecting shaft for unilateral limiting. Furthermore, the screw's movement distance must be at least greater than the connection length between the limiting rod and the connecting shaft. This results in a prolonged screw rotation time when the connection length is too long, and poor connection stability when it is too short, making it difficult to inject lubricant into the connecting shaft. Therefore, we propose a new car front hood mounting hinge to solve these problems. Utility Model Content

The mounting plate 2 is provided with a connecting mechanism 3 for connecting the mounting plate 2 and the front hood connecting piece 4. The connecting mechanism 3 includes a connecting shaft 31 that rotatably passes through the mounting plate 2 and the front hood connecting piece 4 at one end. The insertion end of the connecting shaft 31 is rotatably connected to a rotating shaft 32. The rotating shaft 32 moves through a pad 33. A limiting rod 34 for limiting the movement of the rotating shaft 32 moves through the rotating shaft 32 on the outer side of the pad 33. A handle 35 for rotating the limiting rod 34 is provided on the end of the limiting rod 34 away from the mounting plate 2. The connecting shaft 31 is a T-shaped shaft. The length of the connecting shaft 31 is greater than the width of the mounting plate 2. The diameter of the rotating shaft 32 is less than or equal to the diameter of the connecting shaft 31. The end of the limiting rod 34 near the mounting plate 2 is threaded. The mounting plate 2 has a threaded hole for matching the limiting rod 34. The handle 35 is on the outer side of the pad 33.

[0022] Rotate handle 35, which drives limit rod 34 to rotate. Limit rod 34 rotates and separates from mounting plate 2. Remove limit rod 34 and shim 33 in sequence, and then pull out connecting shaft 31. Connecting shaft 31 moves and pulls rotating shaft 32 to follow and move out of mounting plate 2. Connecting shaft 31 can be replaced separately. Connecting shaft 31 is integrally formed and supports front cover connecting piece 4 to rotate on mounting plate 2, which makes it easy to replace connecting shaft 31 and avoids affecting the connection stability of mounting plate 2 and front cover connecting piece 4.

[0023] The connecting shaft 31 is provided with a connecting mechanism 5. The connecting mechanism 5 is used to assist the lubricant in entering the contact point between the connecting shaft 31 and the front cover connecting piece 4. The connecting mechanism 5 includes a through hole 51 opened on the connecting shaft 31. A plug 52 is moved and inserted into the outer opening of the through hole 51.

[0024] Remove the plug 52, connect the pneumatic lubricator to the outer end of the through hole 51, and inject lubricant into the through hole 51 through the pneumatic lubricator. The lubricant is discharged through two openings away from the plug 52 and enters the connection between the connecting shaft 31 and the front cover connecting piece 4, which makes it easier to inject lubricant into the connection between the connecting shaft 31 and the front cover connecting piece 4, thus improving the performance.

[0025] Working principle: This utility model rotates the handle 35, which drives the limiting rod 34 to rotate. The limiting rod 34 rotates and separates from the mounting plate 2. The limiting rod 34 and the gasket 33 are removed in sequence. Then, the connecting shaft 31 is pulled out. The connecting shaft 31 moves and pulls the rotating shaft 32 to follow and move out of the mounting plate 2. The connecting shaft 31 can be replaced separately. The connecting shaft 31 is integrally formed and supports the front cover connecting piece 4 to rotate on the mounting plate 2, which makes it easy to replace the connecting shaft 31 and avoids affecting the connection stability of the mounting plate 2 and the front cover connecting piece 4. The plug 52 is removed. By connecting the pneumatic oiler to the outside of the through hole 51, lubricant is injected into the through hole 51 through the pneumatic oiler. The lubricant is discharged through two openings away from the plug 52 and enters the connection between the connecting shaft 31 and the front cover connecting piece 4, which makes it easy to inject lubricant into the connection between the connecting shaft 31 and the front cover connecting piece 4, thus improving the use effect.

[0026] Pneumatic oil injectors are existing technology and will not be discussed further here.
