Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a hinge mechanism for a central armrest of a rear seat. Background Art

[0002] A hinge is a mechanical device used to connect two solids and allow them to rotate relative to each other. A hinge can be made of movable components or foldable materials. Hinges are mostly installed on cabinets. According to the material classification, they are mainly divided into stainless steel hinges and iron hinges. In order to give people a better enjoyment, hydraulic hinges (also known as damping hinges) have appeared. Their characteristics are that they provide a buffering function when the cabinet door is closed, which minimizes the noise caused by the collision between the cabinet door and the cabinet body when the cabinet door is closed. If the hinge quality is poor, the cabinet door will easily fall forward and backward, loosen and sag after being used for a long time. Almost all cabinet hardware of big brands uses cold-rolled steel, which is stamped and formed in one time, with a thick feel and a smooth surface. Moreover, due to the thick surface coating, it is not easy to rust, is strong and durable, and has a strong load-bearing capacity. Inferior hinges are generally welded from thin iron sheets, with almost no resilience. They will lose elasticity after a long time of use, resulting in the cabinet door not closing tightly or even cracking.

[0003] The application number is CN202220231478.5, which discloses a car central armrest box hinge, including a box cover bracket and a box body bracket, a left hinge arm of the box cover bracket is provided on the left side of the front end of the box cover bracket, and a right hinge arm of the box cover bracket is provided on the right side of the front end of the box cover bracket, the left hinge arm of the box body bracket is provided on the left side of the box body bracket, and the right hinge arm of the box body bracket is provided on the right side; the box cover bracket opening force applying mechanism is located between the front ends of the left hinge arm of the box cover bracket and the right hinge arm of the box body bracket facing each other, the right end of the bracket hinge shaft is hinged to the front end of the right hinge arm of the box body bracket, and the left end is hinged to the front end of the left hinge arm of the box body bracket, the front side surface of the front end of the right hinge arm of the box body bracket is provided with a torsion spring foot hook with a flange, and the upper part of the box body bracket is provided with a torsion spring foot blocking notch and a torsion spring foot blocking seat; the box cover bracket opening force applying mechanism includes a bracket hinge shaft sleeve, a left torsion spring, a right torsion spring, a left damping sleeve and a right damping sleeve. The box cover bracket is made to fully open autonomously and to be reliably maintained in the open position without abnormal falling.

[0004] Although the above utility model uses the box cover bracket opening force applying mechanism including the bracket hinge sleeve, left torsion spring, right torsion spring, left damping sleeve and right damping sleeve to make the box cover bracket fully open autonomously and reliably maintain the open position without abnormal falling, the disadvantage is that the device is not provided with a shock absorbing component when in use, so when the lid is opened and closed with great force during use, the fixing bolts may become loose due to vibration and the hinge may be damaged to a certain extent.

[0005] Therefore, it is necessary to install a shock-absorbing component on the device so that when the central armrest is opened and closed with great force during use, the shock-absorbing component arranged in the middle of the hinge can reduce the damage to the hinge caused by the vibration to a certain extent, as well as the looseness of the installation, thereby continuing the effect of the reinforced installation.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is a hinge mechanism for a central armrest of a rear seat, comprising a main body component, a shock absorbing component and a limit component, wherein the shock absorbing component is installed on the side and front end of the main body component, and the limit component is installed on the bottom thereof, the shock absorbing component comprises a front shock absorbing protection pad and a side shock absorbing protection pad, the front shock absorbing protection pad is installed on both sides of the front bottom end of the base plate, and the side shock absorbing protection pad is installed on the outer sides of both sides of the side plates.

[0009] Furthermore, the main body assembly includes side panels, a rear panel is installed at the rear end of the side panels, and a bottom panel is installed in the middle of the two side panels.

[0010] Furthermore, the limiting assembly comprises a slideway shell, and a slide groove is provided in the middle of the slideway shell.

[0011] Furthermore, the side plate includes a fixing hole and a bottom fixing hole, a lubrication ring is installed around the fixing hole, the bottom fixing hole is installed at the bottom of the front sides of the side plate, and a mounting groove is opened on one side of the bottom of the rear plate.

[0012] Furthermore, the lubricating ring comprises an oil storage sponge body, and a plurality of oil outlet holes are opened around the inner side of the oil storage sponge body.

[0013] Furthermore, the front shock-absorbing protective pad includes a sound-absorbing port, a sound-absorbing cotton board is installed at the bottom of the sound-absorbing port, a shock-absorbing spring is installed at the bottom of the sound-absorbing cotton board, a supporting sponge layer is installed around the shock-absorbing spring, and a sound insulation board is installed at the bottom of the supporting sponge layer.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model is a rear seat center armrest hinge mechanism. By installing a shock absorbing component on the device, when the center armrest cover is opened and closed with great force during use, the shock absorbing component arranged in the middle of the hinge can reduce the damage to the hinge caused by vibration to a certain extent, and can also reduce the looseness of the installation, thereby maintaining the effect of reinforcing the installation.

[0016] (2) The utility model is a rear seat center armrest hinge mechanism. By installing a lubricating ring inside the mounting hole in the device, a certain oil discharge effect can be achieved when the bolts are tightened and fixed during installation, thereby having a certain lubrication effect, thereby avoiding the noise problem caused by rusting over a long period of use.

[0017] (3) This Association uses a new type of hinge mechanism for the center armrest of the rear seat. By installing a limit assembly at the bottom of the device, the hinge can be slid onto the corresponding plate and then fixed in the corresponding fixing hole during installation. This has a better fixing effect and can effectively prevent the entire armrest from falling due to loosening of the fixing bolts.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
