Description

Technical Field

[0001] The utility model relates to the technical field of armrest hinges, in particular to an armrest hinge. Background Art

[0002] A hinge is a mechanical device used to connect two solid objects and allow them to rotate relative to each other. Hinges can be made of movable components or foldable materials. Hinges are often installed on cabinets and are categorized by material into stainless steel and iron hinges. To provide a more comfortable experience, hydraulic hinges (also known as damping hinges) have emerged. Their characteristic is that they provide a cushioning effect when the cabinet door closes, minimizing the noise caused by the door colliding with the cabinet body.

[0003] In car interiors, armrests are often installed between two seats so that car drivers can place their arms when driving for a long time, so that their arms can get an effective rest and not become numb or stiff. In order to make the armrests more useful, the armrests are hinged to the box so that items can be stored.

[0004] Existing armrest hinges are mostly installed with bolts. However, cars inevitably encounter bumpy roads during driving, which causes vibration and shaking. As the car is used throughout its life cycle, the bolts gradually loosen, causing the armrest to make unusual noises during driving, affecting the driver's driving experience and even causing the armrest to fall loose. To address this problem, we have proposed an armrest hinge to address this issue. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-Figure 5 , an armrest hinge, comprising a first mounting plate 1, a plurality of first strip-shaped mounting holes 3 are opened on the first mounting plate 1, a second mounting plate 2 is provided above the first mounting plate 1, the second mounting plate 2 is rotatably connected to the first mounting plate 1, and a plurality of second strip-shaped mounting holes 4 are opened on the second mounting plate 2; wherein, Figure 1 and Figure 2 As shown, a support plate 5 is vertically installed in the middle of the side of the first mounting plate 1 close to the second mounting plate 2, and fixed plates 6 are symmetrically installed at the bottom of both ends of the support plate 5 away from the first mounting plate 1. A connecting plate 8 is provided on the side relatively far away from the two fixed plates 6, which is bent upward into an "L" shape near one end of the first mounting plate 1. One end of the connecting plate 8 is rotatably connected to the fixed plate 6 through a rotating shaft 7, and the other end of the connecting plate 8 is fixed to the second mounting plate 2, forming a rotating connection between the first mounting plate 1 and the second mounting plate 2, so that the second mounting plate 2 can be freely flipped on the support plate 5.

[0027] It should be noted that if Figure 1As shown, a slot 10 corresponding to the connecting plate 8 is opened on the first mounting plate 1, and the second mounting plate 2 is flipped toward the side of the first mounting plate 1 away from the support plate 5, so that the first mounting plate 1 does not cause obstruction to the connecting plate 8, thereby affecting the flipping process of the second mounting plate 2.

[0028] Specifically, when in use, take the first mounting plate 1 and place it on the upper end of the inner wall of the armrest box, then take the bolt corresponding to the first mounting hole 3 and pass it through the first mounting hole 3 to fix the first mounting plate 1 on the armrest box, then flip the second mounting plate 2 so that it is parallel to the first mounting plate 1, then take the armrest and place it on the second mounting plate 2, then take the bolt corresponding to the second mounting hole 4 and pass it through the second mounting hole 4 to fix the second mounting plate 2 to the armrest.

[0029] In order to prevent the second mounting plate 2 from over-flipping, which makes it inconvenient to flip the armrest back onto the armrest box, a limit plate 9 with its bottom bent into an "L" shape toward the support plate 5 is installed at the bottom of each connecting plate 8. As the armrest flips upward, the limit plate 9 will contact the top of the fixed plate 6, so that the fixed plate 6 blocks the limit plate 9, thereby limiting the continued upward flipping of the armrest.

[0030] like Figure 1 and Figure 3 As shown, a cover plate 12 is provided on the side of the first mounting plate 1 close to the second mounting plate 2, and the front projection position of the cover plate 12 corresponds to the position of the first mounting hole 3 on the first mounting plate 1, and an elastic rubber pad is installed on the side of the cover plate 12 close to the first mounting plate 1, and a plurality of spaced pressure plates 21 are provided along the edge of the cover plate 12, and a connecting shaft 22 is vertically installed at one end of the pressure plate 21, and the other end of the connecting shaft 22 is rotatably installed on the first mounting plate 1. After the first mounting plate 1 is fixed to the inner wall of the armrest box, the cover plate 12 is taken and covered on the first mounting plate 1, thereby covering the nut on the first mounting plate 1, and then the pressure plate 21 is rotated to press it on the cover plate 12, thereby completing the detachable installation of the cover plate 12 on the first mounting plate 1. At this time, the cover plate 12 will be tightly attached to the nut of the bolt, thereby exerting an extrusion effect on the bolt, so that the bolt is tightened on the first mounting plate 1, reducing the probability of the bolt loosening on the first mounting plate 1.

[0031] like Figure 4 and Figure 5As shown, a plurality of guide shafts 13 arranged at intervals are vertically installed on one side of the cover plate 12 close to the first mounting plate 1, and the other end of the guide shaft 13 is placed in the sleeve 14, and the sleeve 14 is opened at only one end, and a compression spring 16 is built into the sleeve 14, one end of the compression spring 16 is fixed to the end of the guide shaft 13, and the other end of the compression spring 16 is fixed to the end of the sleeve 14. When the cover plate 12 is placed on the first mounting plate 1, the cover plate 12 can be pressed so that the compression spring 16 will be compressed due to the extension and contraction of the guide shaft 13 in the sleeve 14, and then the cover plate 12 can be released after the pressure plate 21 is rotated onto the cover plate 12. At this time, the compression spring 16 is still in a compressed state, allowing the compression spring 16 to apply an outward pushing force to the cover plate 12, and the limit of the pressure plate 21 is cooperated with to improve the tightness of the cover plate 12 on the first mounting plate 1.

[0032] In order to ensure the stability of the pressure plate 21 on the cover plate 12, a receiving groove 20 corresponding to the pressure plate 21 is opened along the edge of the cover plate 12. That is, after the pressure plate 21 is turned onto the cover plate 12, it can be placed in the receiving groove 20 to limit the pressure plate 21.

[0033] It should be noted that, in order to facilitate the installation of the cover plate 12 on the first mounting plate 1, as shown in FIG. Figure 3 and Figure 4 As shown, a plurality of limit seats 11 are installed on one side of the first mounting plate 1 close to the cover plate 12, and the limit seats 11 correspond one-to-one to the sleeves 14, and a limit hole 15 is opened on the end of the sleeve 14 away from the guide shaft 13, and the limit hole 15 corresponds to the limit seat 11; at least one limit groove 18 is also opened on the first mounting plate 1, and a limit block 19 is installed on the cover plate 12, and the limit block 19 corresponds to the limit groove 18.

[0034] Furthermore, in order to prevent the guide shaft 13 from slipping out of the sleeve 14, Figure 5 As shown, the port radius length of the sleeve 14 is smaller than the inner diameter length of the sleeve 14, and the outer wall of the guide shaft 13 is clearance-matched with the inner wall of the port of the sleeve 14, and a baffle 17 is installed on one end of the guide shaft 13 placed in the sleeve 14. The outer wall of the baffle 17 is clearance-matched with the inner wall of the sleeve 14, which limits the sliding of the guide shaft 13 in the sleeve 14, thereby ensuring that the guide shaft 13 will not fall off from the sleeve 14.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
