Description

Automobile glove box buffer gear

Technical field

The utility model relates to auto industry fields, and in particular to automobile glove box buffer gear.

Background technique

Vehicle copilot person side generally can all be equipped with glove box, to place article, generally use glove box rotation Opening ways.Installation axle on glove box axle sleeve and instrument desk is rotatablely connected, maintenance not easy to disassemble, and axle sleeve and glove box are general It is designed for integral type, the shape of axle sleeve is consistent with installation axis shape, after glove box opening, is hurtled down by gravity to just At the position limiting structure of standing meter, since when personnel are sitting on front chair, glove box is placed exactly in the top of the leg of personnel, institute There is a possibility that comparatively fast directly hitting people's leg because of reversal rate, this mistake if directly being turned under the effect of gravity when falling with glove box Journey can also generate strong shock vibration and impact noise, give low-grade feeling.To overcome problem above, in the prior art The mode for generalling use one air damping part of increase is improved, but for low side vehicle, there are costs for this mode Excessively high problem.

Utility model content

For the problems of the prior art, the utility model provides automobile glove box buffer gear, the technology solved Problem is to slow down the speed that glove box is overturn down such as the resistance that how lower increased costs glove box is subject in switching process Degree.

In order to solve the above technical problems, the present invention provides the following technical scheme that

Automobile glove box buffer gear, including installation axle and glove box, it is characterised in that: glove box is equipped with rotation connection Axle sleeve on the mounting shaft, installation axle are equipped with lug boss in the mating surface with axle sleeve, and axle sleeve is back and forth transported in its opposing projections Dynamic fitting face is equipped with transition part, and transition part is successively arranged first surface and the second curved surface along the direction that glove box is opened, First surface is the circular arc being bonded always with lug boss, and the direction that the curvature of the second curved surface is opened along glove box is increasing.

Axle sleeve is equipped with the fluting that section is " C " shape, and fluting be located in installation axle.

The outer surface portion of installation axle is arranged with for the plane that smoothly be located in thereon of slotting.

Axle sleeve is equipped with limiting section in the open side of transition part, and the lug boss portion of being limited resists when glove box is closed.

Axle sleeve is mutually threadedly coupled with glove box.

Possessed beneficial effect is the utility model compared with prior art: axle sleeve and installation axle on glove box cooperate Curved surface by be designed to it is increasing along the curvature of glove box opening direction, make installation axle protrusion slowly with axle sleeve occur Interference, effectively prevents shock and noise sharply, during so that glove box is opened whereabouts in the case where not increasing damping part There are buffering course, and the replacement easy to repair of dismountable axle sleeve, so that cost be greatly saved.

Specific embodiment

As Figure 1-Figure 4, this automobile glove box buffer gear, including installation axle 2 and glove box 10, on glove box 10 Equipped with the axle sleeve 1 being rotatably connected in installation axle 2, installation axle 2 with lug boss 3 is equipped in the mating surface of axle sleeve 1, axle sleeve 1 exists The fitting face that its opposing projections 3 moves back and forth is equipped with transition part, and transition part is successively set along the direction that glove box 10 is opened There are first surface 43 and the second curved surface 41, opens glove box 10, and glove box 10 is fallen around the rotation of installation axle 2, lug boss 3 is first By first surface 43, first surface 43 is the circular arc being bonded always with lug boss 3, and the purpose being arranged in this way is to turn over axle sleeve 1 Its first surface 43 is maintained at the state being smoothly bonded with lug boss 3 when turning, and the two does not interact, and makes axle sleeve 1 in this rank Section is not only overturn by gravity by the tangential force effect of lug boss 3, and in the present embodiment, axle sleeve 1 rotates 20 ° or so rear peaces The lug boss 3 of axis 2 is filled into contact with the second curved surface 41 with buffer function, because the curvature of the second curved surface 41 is along glove box The direction of 10 unlatchings is increasing, so with the rotation of axle sleeve 1, the generation between installation axle 2 and the second curved surface 41 of axle sleeve 1 Interference it is increasing, interfere the frictional force of generation also increasing, finally gradually decrease glove box 10 rotation speed until It is parked in fixed position.The configuration achieves the technology effects turning over terminal-velocity degree and effectively being slowed down after opening to glove box 10 Fruit enhances the service performance of glove box 10, and its cheap sense is effectively reduced, and avoids it because quickly overturning the people hit on seat Leg, security performance also effectively enhanced.

Axle sleeve 1 is equipped with the fluting 61 that section is " C " shape, and fluting 61 be located in installation axle 2, the outer surface portion of installation axle 2 It is arranged with the plane that smoothly be located in for fluting 61 thereon, when glove box 10 is installed in installation axle 2, by the fluting of axle sleeve 1 The lug boss 3 of 61 opposite installation axles 2 simultaneously makes the both-side opening end of fluting 61 finally be buckled in installation along the plane of 2 two sides of installation axle The outside of axis 2.The setting of this structure is convenient to carry out assembly and disassembly to the glove box 10 being mounted in installation axle 2.

Axle sleeve 1 is equipped with limiting section 42 in the open side of transition part, and lug boss 3 is limited portion 42 and supports when glove box 10 is closed Firmly, such glove box 10 will not be overturn during closing excessively causes to damage.

Axle sleeve 1 is threadedly coupled with 10 phase of glove box, and this dismountable structure facilitates the abrasion of day rear axle housing 1 to be individually replaced axis Set 1, to save cost.

The working principle of the present embodiment is as follows:

When operation, user opens glove box 10, when glove box 10 is downwardly turned over around installation axle 2, when lug boss 3 is in first When within the scope of the correspondence of curved surface 43, the state for freely being accelerated to overturn by gravity is presented in glove box 10, when lug boss 3 is into the When the correspondence range of two curved surfaces 41, lug boss 3 starts to generate increasing frictional force with the second curved surface 41, so that glove box 10 Gradually slow down and overturn, with the increase of flip angle, frictional force suffered by axle sleeve 1 is also increasing, is stopping glove box 10 It is more next small that the speed fallen is turned over before rotation, and is finally stopped overturning；When user closes glove box 10,10 backwards rotation of glove box is simultaneously Its limiting section 42 is finally set to resist the lug boss 3 of installation axle 2.
