Description

Technical Field

[0001] The invention relates to the technical field of automobile armrests, and in particular to an automobile armrest hinge device with a buffering function. Background Art

[0002] As one of the indispensable parts of a car, the car central armrest is also called the car armrest. It was originally designed to provide elbow support for passengers. Later, it developed into a storage box in the car, including an armrest panel, which can facilitate conversation, office work, reading documents, etc.

[0003] In order to enable the vehicle armrest to be opened and closed normally, the vehicle armrest generally uses a hinge device to connect the vehicle armrest and the vehicle, thereby facilitating the normal opening and closing of the vehicle armrest.

[0004] In the existing traditional armrest box, a metal pin is often used as a rotating shaft between the box cover and the box body. The metal pin is passed through the holes on the box body and the box cover to connect the box body and the box cover as a whole, and the box cover can rotate around the rotating shaft. When the box cover is closed, the box cover will fall quickly in free fall and collide with the box body, causing a loud noise. At the same time, in order to reduce the impact, a rubber pad will be set at the contact part, but the rubber pad still has a good buffering effect on the impact of the falling armrest box, and still generates a large contact force. For this reason, we propose a car armrest hinge device with a buffering function. Summary of the invention

[0005] The object of the present invention is to provide a car armrest hinge device with a buffering function.

The fixed plate 1 is connected to the car through other connecting parts of the prior art. The connecting plate 3 is connected to the armrest, and the connecting plate 3 is driven by the armrest to fall freely. When the armrest falls close to the horizontal position, the connecting plate 3 will contact and squeeze the pressure component 7, so that the pressure component 7 moves, and then drive the movable component 11 to move. The movable component 11 will slide downward along the fixed column 10, thereby squeezing the vertical buffer spring 12 and the transverse buffer spring 13, and utilizing the deformation of the vertical buffer spring 12 and the transverse buffer spring 13 to buffer the armrest, which can better prevent the armrest from hitting the box body and also reduce noise.

[0029] It should be further explained that the movable component 11 includes a movable sleeve 1101 plugged into the fixed column 10, a rectangular hole 1102 opened in the middle of the movable sleeve 1101, a movable rod 1103 plugged into the inside of the movable sleeve 1101 and a movable groove 1104 opened in the middle of the movable rod 1103, and the interior of the rectangular hole 1102 is plugged into the fixed column 10; when the pressure component 7 is squeezed, it will drive the movable groove 1104 on the movable rod 1103 to move along the fixed column 10, and at the same time drive the rectangular hole 1102 on the movable sleeve 1101 to move downward along the fixed column 10, thereby compressing the vertical buffer spring 12.

[0031] It should be further explained that two mounting holes 2 are provided on both sides of the fixing plate 1, and the fixing plate 1 is connected through the cooperation between the mounting holes 2 and the mounting screws; by inserting the mounting screws into the mounting holes 2, the fixing plate 1 is connected to the connecting piece, thereby facilitating the fixing plate 1 to be fixed to the car.

[0032] Furthermore, the connecting plate 3 includes a flip plate 301, a side plate 302 fixedly connected to both sides of the flip plate 301, and a plurality of connecting holes 303 opened on the outer surface of the flip plate 301, one side of the side plate 302 is fixedly connected to the end face of the corresponding hinge shaft 4; the connecting hole 303 on the flip plate 301 is cooperated with the screw to connect the flip plate 301 to the armrest, and when the armrest rotates, the armrest drives the flip plate 301 to rotate, so that the side plate 302 drives the hinge shaft 4 to rotate.

[0033] It should be noted that the vertical plate 5 includes a first plate body 501 and a second plate body 502 fixedly connected to one side of the middle part of the first plate body 501, and one side of the second plate body 502 is fixedly connected to the corresponding support plate 8; a connecting assembly 6 is arranged between the vertical plate 5 and the fixed plate 1, and the connecting assembly 6 includes a connecting bolt 601 passing through the fixed plate 1 and the first plate body 501 and a connecting nut 602 threadedly connected to one end of the connecting bolt 601; the first plate body 501 is placed on the side of the fixed plate 1, and then the connecting bolt 601 is inserted into the fixed plate 1 and the first plate body 501, and then the connecting nut 602 is rotated to screw the connecting nut 602 with the connecting bolt 601, so as to connect the fixed plate 1 and the vertical plate 5 using the connecting assembly 6.

Since the thickness dimension of the buffer plate 702 increases from top to bottom, the side plate 30 2 will squeeze the buffer plate 702, so that the buffer plate 702 gradually moves outward until the side plate 302 squeezes the bearing plate 703, and then squeezes the transverse buffer spring 13. When the armrest is in a horizontal position, which is also when the armrest is reset, the side plate 302 will still squeeze the bearing plate 703, thereby squeezing the vertical buffer spring 12 and the transverse buffer spring 13. At the same time, the buffer plate 702 can squeeze the side plate 302 to a certain extent, thereby temporarily fixing the armrest. Here, the thickness size behind the buffer plate 702 can also be changed to increase from the top to the middle, and the thickness size from the middle to the bottom remains unchanged, thereby better temporarily fixing the armrest.

[0035] Furthermore, the two buffer mechanisms are symmetrically arranged, the internal width dimension of the movable groove 1104 is adapted to the width dimension of the fixed column 10, the internal cross-sectional profile dimension of the movable sleeve 1101 is adapted to the external cross-sectional profile dimension of the movable rod 1103, and the external cross-sectional profile of the fixed column 10 and the external cross-sectional profile of the movable rod 1103 are both set to be rectangular; it is convenient for the movable sleeve 1101 to use the rectangular hole 1102 to stably move along the fixed column 10, and at the same time, the movable rod 1103 can use the movable groove 1104 to move stably to the side along the fixed column 10.
