[0001] The utility model relates to the technical field of automobile interior decoration, in particular to an installation structure of a damper for an automobile armrest box. Background Art

[0002] Generally, an automobile armrest box includes a box body and a box cover. The box cover is rotatably installed on the top of the box body through a hinge. A lock is provided between the box cover and the box body to lock the two. The lock generally has a button. When unlocking, it is necessary to press the button to open the box cover. In order to enable the box cover to automatically open after pressing the button, a torsion spring is provided between the box cover and the box body, and the torsion spring's own elastic force is used to drive the box cover to open. In actual application, the elastic force of the torsion spring is generally relatively large. When unlocking, the box cover will quickly bounce up, so the situation where the box cover hits the palm will occur. Therefore, generally, a damper is provided in the hinge of the box body and the box cover to buffer the impact force when closing or opening the box cover. For the existing armrest boxes, the installation structure of their dampers is generally relatively complex or has a short service life, and there is a problem of high manufacturing cost.

[0024] The present invention discloses a specific embodiment of the damping device installation structure of the automotive armrest box. Please refer to Figures 1 to 2 , which includes a box body 1, a box cover 2 and a damper assembly 3.

[0025] In this embodiment, the box cover 2 is provided with paired and spaced-apart mounting portions 11. The mounting portions 11 and the box cover 2 are integrally formed structures. Each mounting portion 11 is provided with a through hole. A rotating shaft is provided between the paired mounting portions 11. During installation, the rotating shaft is inserted through the through holes of the two mounting portions 11, and the outside of the end of the rotating shaft can be fixed against detachment by means of a clamp or a retaining piece.

[0026] In this embodiment, the lid 2 extends towards the rotating shaft to form a pair of rotating arms 21. The shape and structure of the rotating arms 21 can be selectively set according to actual requirements. A first through hole 22 is provided at the end of each rotating arm 21, and the rotating shaft is inserted through each first through hole 22. The first through hole 22 is in a rotatable state relative to the rotating shaft.

[0027] In this embodiment, as Figure 1 and Figure 2 shown, a damper assembly 3 is provided between each mounting portion 11 and the rotating arm 21. The damper assembly 3 includes a mounting sleeve 31, a damper housing 32, and a damper rotor 33. In Figure 2 it, two damper assemblies 3 are shown. The damper assembly 3 on the left is not disassembled, and the damper assembly 3 on the right is disassembled into a mounting sleeve 31, a damper housing 32, and a damper rotor 33.

[0028] In this embodiment, the damper rotor 33 is sleeved on the rotating shaft, and the damper rotor 33 is inserted and fixed to the mounting portion 11. Optionally, the damper rotor 33 extends towards the mounting portion 11 to form a pair of spaced-apart insertion portions 331. A third through hole penetrating the damper rotor 33 is provided between the pair of insertion portions 331. The rotating shaft is inserted into the third through hole. The mounting portion 11 is provided with a slotted hole 111. In this state, the insertion portion 331 is inserted into the slotted hole 111, and the length of the insertion portion 331 is slightly greater than the width of the slotted hole 111 to achieve an interference fit, so that the slotted hole 111 can limit the insertion portion 331 to prevent the damper rotor 33 from rotating, that is, the damper rotor 33 is fixed relative to the box body 1. The damper rotor 33 can be made of hard rubber or a material with a large roughness, as long as it can provide a certain frictional force to relieve the impact.

[0029] In this embodiment, the damper housing 32 is sleeved on the outer peripheral side of the damper rotor 33, and the damper housing 32 can rotate relative to the damper rotor 33. By selecting different materials for the two, a certain frictional force can be generated when the damper housing 32 rotates relative to the damper rotor 33, that is, it can play a damping role.

[0030] In this embodiment, the mounting sleeve 31 is sleeved on the outer peripheral side of the damper housing 32. The mounting sleeve 31 is fixed relative to the damper housing 32, and the end of the mounting sleeve 31 is inserted and fixed to the rotating arm 21. Optionally, as Figure 2 shown, two damper assemblies 3 are shown. The damper assembly 3 on the left is not disassembled, and the damper assembly 3 on the right is disassembled into a mounting sleeve 31, a damper housing 32, and a damper rotor 33. The first through hole 22 of the rotating arm 21 is rectangular, and the mounting sleeve 31 is a semi-closed cylindrical structure. The closed side of the mounting sleeve 31 extends outwards to form a rectangular clamping block 312 ( Figure 2The undismantled damper assembly 3 can be shown), and the corresponding first through hole 22 is also rectangular. In this state, the clamping block 312 is inserted into the first through hole 22, so that when the rotating arm 21 rotates, it can drive the mounting sleeve 31 to rotate. The clamping block 312 is provided with a second through hole for the rotating shaft to pass through.

[0031] In this embodiment, as Figure 3 shown, a convex strip 321 protruding outward is formed on the outer peripheral side of the damper housing 32, and a groove 311 is formed on the inner wall of the mounting sleeve 31. In the assembled state, the convex strip 321 is inserted into the groove 311. In other embodiments, a groove 311 recessed inward is formed on the outer peripheral side of the damper housing 32, and a convex strip 321 is formed on the inner wall of the mounting sleeve 31. In the assembled state, the convex strip 321 is inserted into the groove 311, as long as it can be realized that when the mounting sleeve 31 rotates, it can drive the damper housing 32 to rotate.

[0032] Due to the characteristics of the rectangle, after the mounting sleeve 31 is clamped with the rotating arm 21, the mounting sleeve 31 is fixed relative to the rotating arm 21. When the flip cover 2 is flipped, the rotating arm 21 of the cover 2 will drive the mounting sleeve 31 to rotate. Since the mounting sleeve 31 is inserted and fixed with the damper housing 32, when the mounting sleeve 31 rotates, it will drive the damper housing 32 to rotate together, so as to realize the rotation of the damper housing 32 relative to the damper rotor 33. Since the damper rotor 33 is fixed to the box body 1, the rotation of the cover 2 relative to the box body 1 is realized. The specific setting between the damper housing 32 and the damper rotor 33 can provide a certain frictional force, so as to play a buffering role.

[0033] In this embodiment, an installation structure of a damper for an automobile armrest box has a simple and compact overall structure of the damper assembly 3. After the damper assembly 3 is installed on the armrest box, it can play a buffering role, relieve the impact force when the cover 2 is opened or closed, and the damper assembly 3 is very convenient to disassemble and install, solving the problem of the previous complex structure.

[0034] Finally, it should be noted that: what is disclosed in an installation structure of a damper for an automobile armrest box according to an embodiment of the present invention is only a preferred embodiment of the present invention, only for explaining the technical solution of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that; they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
