TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile armrest, in particular to an automobile armrest hinge assembly. BACKGROUND

[0002] At present, many automobile armrest covers have many problems when being opened. Since the resistance between the upper rotating arm of the hinge and the hinge shaft is small, the customer cannot control the positioning and fixing state of the armrest cover when it is opened, so when the armrest cover is opened, it often falls down automatically and hits the hand, which seriously affects the customer's experience. Directly fixing the hinge on the automobile armrest cover will cause installation difficulties. SUMMARY

[0003] The purpose of the present application is to overcome the defects of the prior art, such as the inability to control the state of the armrest cover when it is opened and the difficulty in installation, and to provide an automobile armrest hinge assembly connected with the cover sleeve by a hinge shaft.

[0004] The purpose of the present application can be achieved by the following technical solutions:

[0005] The technical scheme of the present application provides an automobile armrest hinge assembly, which comprises a lower hinge support, an upper hinge rotating arm, a hinge shaft connecting the lower hinge support and the upper hinge rotating arm, a first damper cover and a second damper cover arranged on the hinge shaft and placed on both sides of the lower hinge support, and a sleeve arranged between the lower hinge support and the hinge shaft. The lower hinge support and the sleeve form a transition fit connection, the hinge shaft and the upper hole of the sleeve form an interference and friction fit, and the hinge shaft and the upper hinge rotating arm are interference rotatingly connected, so that the upper hinge rotating arm can be fixed on the hinge shaft when it is rotated to any position.

[0006] Further, the hinge shaft is provided with two, respectively arranged at the connection between the lower hinge support and the upper hinge rotating arm.

[0007] Further, the hinge shaft is provided with a straight grain knurling area, and the upper hinge rotating arm and the straight grain knurling area on the hinge shaft form an interference rotating connection.

[0008] Further, the outer surface of the sleeve is provided with a special-shaped surface area for transition fit connection with the lower hinge support.

[0009] Further, the end of the lower hinge support is provided with a special-shaped hole for embedding the sleeve.

[0010] Further, the rotating resistance between the hinge shaft and the upper hinge rotating arm is smaller than the resistance between the hinge shaft and the sleeve.

[0011] Further, rivets are arranged on the first damper cover plate and the second damper cover plate for fixing the shaft sleeve.

[0012] Further, the rivets are at least four. At least two rivets are arranged at a connection between the hinge lower support and the hinge upper rotating arm for fixing the shaft sleeve of the first damper cover plate and the second damper cover plate.

[0013] Further, a gasket is arranged between the hinge upper rotating arm and the first damper cover plate.

[0014] Further, the shaft sleeve is an open shaft sleeve for preventing burst.

[0015] Further, the first damper cover plate and the second damper cover plate are both friction damper cover plates, so that the first damper cover plate and the second damper cover plate can generate sufficient friction resistance with the hinge shaft.

[0016] Compared with the prior art, the present application has the following beneficial effects:

[0017] (1) The hinge is stamped and formed, simple in structure, convenient to manufacture, and capable of being mass-produced.

[0018] (2) The hinge is connected by a rotating shaft, so that installation and disassembly are convenient, and the problem of installation difficulty when the hinge is directly fixed to the automobile armrest cover plate is avoided.

[0019] (3) The hinge upper rotating arm is connected by interference rotation between the hinge upper rotating arm and the straight grain knurling area of the hinge shaft, so that the hinge upper rotating arm can be fixed at any position during the opening and closing process of the hinge upper rotating arm.

[0025] The application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] In the following embodiments, the functional components or structures not specifically described are all conventional components or structures used in the field to achieve the corresponding functions.

[0027] Embodiment 1:

[0028] As Figures 1-2 shown is a structural schematic diagram of an automobile armrest hinge assembly, which comprises a hinge lower support 8, a hinge upper rotating arm 7, a hinge shaft 1 connecting the hinge lower support 8 and the hinge upper rotating arm 7, a first damper cover plate 2 and a second damper cover plate 3 arranged on the hinge shaft 1 and placed on both sides of the hinge lower support 8, a shaft sleeve 4 arranged between the hinge lower support 8 and the hinge shaft 1, and a gasket 6 arranged between the hinge upper rotating arm 7 and the first damper cover plate 2. The end of the hinge lower support 8 is provided with a special-shaped hole for embedding the shaft sleeve 4, and the shaft sleeve 4 is an open shaft sleeve for preventing burst. The first damper cover plate 2 and the second damper cover plate 3 are both friction damper cover plates, so that the first damper cover plate 2 and the second damper cover plate 3 can generate a large enough friction resistance with the hinge shaft 1. The first damper cover plate 2 and the second damper cover plate 3 are further provided with rivets 5 for fixing the shaft sleeve 4, and at least two rivets are arranged at a connection between the hinge lower support 8 and the hinge upper rotating arm 7 for fixing the shaft sleeve of the first damper cover plate 2 and the second damper cover plate 3. The hinge shaft 1 is provided with two, which are respectively arranged at the connection between the hinge lower support 8 and the hinge upper rotating arm 7 at both ends. The hinge shaft 1 is provided with a straight-line knurling area, and the hinge upper rotating arm 7 and the straight-line knurling area on the hinge shaft 1 form an interference rotating connection. The outer surface of the hinge shaft 1 is provided with a special-shaped surface area for transition fit connection with the hinge lower support 8, the hinge lower support 8 and the shaft sleeve 4 form a transition fit connection, and the hinge shaft 1 and the upper shaft hole of the shaft sleeve 4 form an interference and friction fit. The rotating resistance between the hinge shaft 1 and the hinge upper rotating arm 7 is smaller than the resistance between the hinge shaft 1 and the shaft sleeve 4, so that when the hinge upper rotating arm 7 rotates around the hinge shaft 1, the shaft sleeve 4 will not rotate.

[0029] The assembly process of the application is as follows: first, the hinge upper rotating arm 7 is sleeved on the hinge shaft 1, the gasket 6 is put in, the shaft sleeve 4 is embedded in the groove of the hinge lower support 8, the first damper cover plate 2 and the second damper cover plate 3 are respectively placed on both sides of the hinge lower support 8 and the shaft sleeve 4 is connected and fixed by the rivets 5, and finally the hinge shaft 1 is sleeved.

[0030] As Figure 3The structure schematic view of the application assembled in the car is shown, first, the positioning hole on the upper hinge rotary arm 7 is put into the positioning column, the positioning hole is set so that it can be positioned stably with the armrest cover plate, then the upper hinge rotary arm 7 is fixed on the armrest cover plate through self-tapping screw, the lower hinge support 8 is fixed on the armrest body through the same method, the screw is connected with the threaded hole, the structure is firm and reliable, the application is convenient to install, and the problem of installation difficulty when the hinge is directly fixed on the armrest cover plate is avoided.

[0031] The above description of the embodiments is for facilitating the ordinary skilled person in the art to understand and use the application. The person skilled in the art can obviously easily make various modifications to the embodiments, and apply the general principles described herein to other embodiments without creative labor.
