Description
Technical field
The utility model relates to technical field of automobile parts, relates in particular to a kind of unlatching damping structure and glove box.
Background technique
There are following two kinds of opening ways in the glove box of traditional riding vehicle: open and directly open by opening damping structure.High-grade car adopts the mode that damping structure is opened of opening more, and it opens damping structure and be mostly that damping cylinder or damper realize that this type of damping structure required precision is high, and price is expensive, and the damper reliability of low price is difficult to again guarantee.The lower riding vehicle glove box of price all adopts and opens damping structure in order to save cost, and it is poor to cause glove box to open feel; And owing to there is not damping structure; Glove box is opened to limit position to be stopped suddenly, and impact force is big, makes limit structure fracture and then inefficacy easily.

Embodiment
Unlatching damping structure and glove box that the utility model proposes specify as follows in conjunction with accompanying drawing and embodiment.
As shown in Figure 1; Unlatching damping structure according to a kind of mode of execution of the utility model; Comprise: first gear 1 of engagement fit and second gear, 2, the first gears 1 are free gear, and second gear 2 is a fixed gear; And the centre distance of two gears is less than the reference radius sum of two gears, and the interfering edge between the relative movement of first gear 1 and second gear 2 forms the resistance of the unlatching damping structure of the utility model.In the unlatching damping structure of this mode of execution, two gears are involute spur gear.Second gear 2 can be the part of the straight toothed spur gear shown in Fig. 1, and promptly one section circular arc portion also can be tooth bar.
If the centre distance of two gears is when just in time being two gear compound graduations circles (shown in the dotted line, being respectively standard pitch circle R1, standard pitch circle R2 among the figure) radius sum, and two standard pitch circles are just tangent, and the gear normal engaged can not produce any interference.Therefore, in order to produce resistance, in the unlatching damping structure of the utility model, the centre distance of two gears is slightly less than two reference radius sums, and at this moment, standard pitch circle intersects during two gear engagement, and gear engagement produces interferes, so resistance produces.
In order to make the gear can long-term stable operation under the interference engagement working condition; The involute spur gear that second gear 2 in the unlatching damping structure of this mode of execution was made amendment for the flank of tooth; Its flank of tooth is sheared along two chis wheel interference engagement point, and flank profil is incomplete involute on the flank of tooth of formation.Shown in Fig. 2 (a); The flank of tooth of second gear 2 is the plane from the part of standard pitch circle to root cylinder; In this mode of execution preferably this part be plane perpendicular to the root cylinder of second gear 2; And shown in Fig. 2 (b), first gear 1 still is the straight toothed spur gear of complete involute for flank profil.
As shown in Figure 1; When first gear 1 during with direction shown in arrow rotation and with second gear, 2 engagement fit; Each gear teeth for first gear 1; When a lateral tooth flank of the gear teeth of the one of which lateral tooth flank and second gear 2 met at the P1 point, two gears got into interference region: the part of standard pitch circle to the tip cylinder of first gear, 1 gear teeth produces damping with the part interference engagement of standard pitch circle to the tip cylinder of second gear, 2 gear teeth; Because second gear, 2 flank of tooth are the plane perpendicular to its root cylinder from the part of standard pitch circle to root cylinder; When a lateral tooth flank of the gear teeth of the lateral tooth flank of each gear teeth of first gear 1 and second gear 2 meets at interference engagement point P2 (two gear compound graduations circle intersection point); Two gears are not interfered, only tangent engagement; After this, along with the rotation of first gear 1, the opposite side flank of tooth of the opposite side flank of tooth of each gear teeth of first gear 1 and the gear teeth of second gear 2 rises when meeting at the P3 point, and two gears break away from interferes, and does not produce damping.
To sum up, two gears can not make whole tooth surface all be in interference engagement only in certain regional interference engagement, can avoid gear to cause the broken teeth phenomenon because of interference like this.Thereby gear can steady in a long-term be moved.
The utility model also provides a kind of glove box that comprises above-mentioned unlatching damping structure.As shown in Figure 3, comprise according to this glove box of a kind of mode of execution of the utility model: first gear 1, second gear 2, casing 3 and case lid.
Wherein, the sidewall of casing 3 is provided with arc-shaped rail 3-1 (being preferably the one section circular arc homocentric with second gear 2), and second gear 4 is fixed on the sidewall of casing 3.The base of case lid 4 bases and casing 3 is hinged.First gear 1 can be arranged on the position limit pin 5 around its axle center rotationally; And fix with screw, this position limit pin 5 (not shown) that links to each other with case lid 4, and when case lid 4 is opened; Can under case lid 4 drives, in arc-shaped rail 3-1, move, come into operation thereby drive the unlatching damping structure.In the glove box opening process; Open damping structure and play certain drag effect, thereby can avoid glove box in opening process, case lid 4 is freely falling body trend and opens rapidly; The bump and the seismism that produce can not appear stopping suddenly when case lid 4 reaches the limit of the position; Have good unlatching feel, open damping structure simultaneously and can also play buffering and position-limiting action, thereby when glove box is opened spacing inefficacy, still can carry out spacing it.
The unlatching limit structure of the utility model also can be applicable in other similar opening structure except that the glove box that is applied to above-mentioned passenger car, does not do at this and gives unnecessary details.
Above mode of execution only is used to explain the utility model; And be not the restriction to the utility model; The those of ordinary skill in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also be made various variations and modification; Therefore all technological schemes that are equal to also belong to the category of the utility model, and the scope of patent protection of the utility model should be defined by the claims.
