A hinge assembly for a car side-opening tailgate

Abstract

This utility model relates to the field of automotive tailgate technology, and in particular to a hinge assembly for a side-opening tailgate, comprising a first connecting seat, a second connecting seat, and a connecting member. By opening the cover and pulling the slide rod, the slide rod drives the piston to move away from the rotating seat, while the spring is compressed, injecting lubricating oil into the inner sleeve through the oil inlet. The first and second connecting seats are bolted to the vehicle body and the door. When the door is opened, the door causes the first connecting seat to rotate, which in turn causes the rotating seat to rotate. The friction between the rotating seat and the ball bearing causes the ball bearing to roll. During the rolling process, the lubricating oil between the inner and outer sleeves is rolled to the contact end between the ball bearing and the rotating seat. Through continuous rolling, the rotating seat and the outer sleeve are automatically lubricated, avoiding jamming and wear caused by prolonged use.

Technical Field

[0001] This utility model relates to the field of automobile tailgate technology, specifically to a hinge assembly for a side-opening automobile tailgate. Background Technology

[0002] In the automotive market, tailgate hinges, which are widely used, lack a limit function. Side hinges can rotate more than 180° along the axis of rotation.

[0003] However, existing side-opening tailgate hinge assemblies cannot be automatically lubricated during use, which makes them prone to wear over time, causing the door to become stuck when opening or closing. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art by proposing a hinge assembly for a side-opening tailgate of an automobile.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a hinge assembly for a side-opening tailgate of an automobile, including a first connecting seat, a second connecting seat, and connecting members. Connecting members are respectively provided on both sides of the first connecting seat, and the connecting members on both sides are arranged symmetrically and mirror images. The outer sides of the connecting members on both sides are connected to the second connecting seat.

[0022] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0023] See attached document Figure 1-4A hinge assembly for a side-opening tailgate of an automobile is characterized in that it includes a first connecting seat 1, a second connecting seat 2, and a connecting member 3. The first connecting seat 1 is provided with connecting members 3 on both sides, and the connecting members 3 on both sides are arranged symmetrically and mirror images of each other. The outer sides of the connecting members 3 on both sides are connected to the second connecting seat 2. The first connecting seat 1 and the second connecting seat 2 are connected to the vehicle body and the door by bolts.

[0024] The connecting component 3 includes a sliding assembly, a rotating shell, and a rotating seat 307. The sliding assembly is disposed inside the rotating shell, and the rotating seat 307 is disposed on the side of the rotating shell away from the sliding assembly. The outside of the rotating seat 307 is fixedly connected to the first connecting seat 1. The first connecting seat 1 can drive the rotating seat 307 to rotate. The rotating seat 307 can rotate along the outer sleeve 302. The friction between the rotating seat 307 and the ball 308 causes the ball 308 to roll. During the rolling process, the lubricating oil between the inner sleeve 301 and the outer sleeve 302 rolls to the contact end between the ball 308 and the rotating seat 307. Through continuous rolling, the rotating seat 307 and the outer sleeve 302 are lubricated.

[0025] The rotating housing includes an inner sleeve 301, an outer sleeve 302, a fixed seat 303, bolts 309, and balls 308. The outer wall of the inner sleeve 301 fits against the outer sleeve 302. The inner wall of the inner sleeve 301 is fixedly connected to the fixed seat 303. The ends of the fixed seat 303 fit against the outer sleeve 302. Multiple balls 308 are arranged between the fixed seat 303 and the outer sleeve 302, and the multiple balls 308 are arranged in a ring at equal angles. The side of the outer sleeve 302 away from the rotating seat 307 is threadedly connected to multiple bolts 309. The outer walls of the bolts 309 are all threadedly connected to the inner sleeve 301. An oil inlet 3011 is provided on one side of the inner sleeve 301. A cap 3012 is provided at the upper end of the oil inlet 3011 for sealing the oil inlet 3011. By opening the cap 3012, the slide rod 305 is pulled. The slide rod 305 drives the piston 304 to move away from the rotating seat 307. At the same time, the spring 306 is compressed, and lubricating oil is injected into the interior of the inner sleeve 301 through the oil inlet 3011.

[0026] One side of the outer wall of the outer jacket 302 is fixedly connected to the second connecting seat 2, and one side of the outer jacket 302 is rotatably connected to the rotating seat 307. The inner ends of the multiple balls 308 are all in contact with the rotating seat 307.

[0027] The sliding assembly includes a piston 304, a slide rod 305, and a spring 306. The two ends of the spring 306 are fixedly connected to the piston 304 and the inner sleeve 301, respectively. The outer wall of the piston 304 is in contact with the inner sleeve 301. The end of the piston 304 adjacent to the spring 306 is fixedly connected to the slide rod 305. The outer wall of the slide rod 305 is slidably connected to the inner sleeve 301. As the ball 308 rolls continuously, the lubricating oil inside the inner sleeve 301 gradually decreases, causing the spring force of the spring 306 to drive the piston 304 to move towards the rotating seat 307, so that the lubricating oil inside the inner sleeve 301 is always in contact with the ball 308.

[0028] Working principle;

[0029] By opening the cover 3012 and pulling the slide rod 305, the slide rod 305 drives the piston 304 to move away from the rotating seat 307. At the same time, the spring 306 is compressed, and lubricating oil is injected into the inner sleeve 301 through the oil inlet 3011. The first connecting seat 1 and the second connecting seat 2 are connected to the vehicle body and the door by bolts. When the door is opened, the door causes the first connecting seat 1 to flip, and the first connecting seat 1 causes the rotating seat 307 to rotate. The friction between the rotating seat 307 and the ball 308 causes the ball 308 to roll. During the rolling process, the lubricating oil between the inner sleeve 301 and the outer sleeve 302 rolls to the contact end between the ball 308 and the rotating seat 307. Through continuous rolling, the rotating seat 307 and the outer sleeve 302 are lubricated, avoiding jamming and wear caused by long-term use.

[0030] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
