Detailed description of the invention
In order to make those skilled in the art better understand technical scheme of the present invention, below in conjunction with accompanying drawing, the present invention is described in detail.
Shown in composition graphs 3-6, the invention provides a kind of brake assembly of arrangements for automotive doors, comprise handle base 10, with the outer handle 20 being rotationally connected with handle base 10, in order to solve defect of the prior art, the present invention proposes following technological improvement: also comprise check mechanism 30, check mechanism 30 comprises the support 31 being fixed in handle base 10, with the brake block being rotationally connected with support 31 by rotating shaft 34, brake block is installed on support 31 by reduction torsion spring 32, and rotating shaft 34 vertically extends, brake block 33 under the effect of side impact force around the shaft 34 near a sideway swivel of outer handle 20 to application position, at application position place, brake block 33 and outer handle 20 against.Adopt this technical scheme, under the shock of side impact force, impact acceleration can make outer handle 20 and brake block 33 produce reverse inertial acceleration simultaneously, and this inertial acceleration makes outer handle 20 produce the first rotation displacement, brake block 33 is made to produce the second rotation displacement, according to ox two law
in same acceleration with in the time, outer handle 20 is identical with the rotation displacement of brake block 33, due to the barycenter of outer handle 20 and the center of rotation of self distance large, and the barycenter of brake block 33 and the center of rotation of self are apart from little, therefore, under the condition turning over identical rotation displacement, little apart from the large angle turned over, and it is large apart from the little angle turned over, thus the differential seat angle formed between outer handle 20 and brake block 33, this differential seat angle makes outer handle 20 before unlocking doors, brake block 33 is positioned at application position, the continuation of outer handle 20 is prevented to rotate, opening by mistake of arrangements for automotive doors is prevented to open, its brake structure is reliable, simultaneously, check mechanism 30 does not increase with the increase of outer handle 20 quality, improve the defect of prior art.
Check mechanism 30 is preferably as follows embodiment with the mounting structure of handle base 10: handle base 10 is provided with fixing hole and card column, and support 31 is provided with fixing hole 311 and blocked hole 312, and card column is plugged in blocked hole 312, and screw passes fixing hole 311 and and screw hole.Particularly, blocked hole 312 and card column are all set to T-shaped structure, during installation, first T-shaped card column are inserted in T-shaped blocked hole 312, then use screw urgent, realize fastening.In this scheme, support 31 adopts clamping with handle base 10 and the connection scheme combined that is spirally connected, and comparatively two ends all adopt screw connection to compare, and both ensure that the reliability of connection, have facilitated assembling again, improve installation effectiveness.
In order to ensure the reliable braking of the external handle 20 of brake block 33, brake block 33 is provided with braking surface 331, and at application position place, braking surface 331 is fitted with the outer wall of outer handle 20.In this scheme, by the setting of braking surface 331, increase brake area, improve the reliability of braking.In the present embodiment, brake block 33 away from braking surface 331 one end simultaneously with the projection 21 of outer handle 20 against, this structure, by increasing brake block 33 externally handle 20 contact site, further increases the reliability of braking, braking effect is strengthened.
Brake block 33 is installed on support 31, concrete structure is: brake block 33 is provided with two parallel-plates 332 away from one end of braking surface 331, two parallel-plates 332 extend to the side away from outer handle 20, and be provided with accommodation space 333 between two parallel-plates 332, rotating shaft 34 penetrates the installing hole being located at two parallel-plates 332 and the reduction torsion spring 32 be placed in accommodation space 333, realizes installing fixing.
In above-mentioned mounting structure, the elastic force in order to avoid reduction torsion spring 32 causes brake block 33 to depart from predeterminated position, and preferred support 31 is provided with limited post 314, and limited post 314 is positioned within the stroke that brake block 33 overturns to the side away from outer handle 20.Particularly, limited post 314 is preferably provided with two, and extend near the side of brake block 33 from support 31 respectively, at end to a close lateral buckling each other, this bending with brake block 33 against, after so arranging, when brake block 33 be subject to reduction torsion spring 32 torsion force and to away from outer handle 20 side upset time, limited post 314 with brake block 33 against spacing, can ensure that brake block 33 is in predeterminated position.It may be noted that the rotating shaft 34 in check mechanism 30 should associate setting with the locus of the axis of rotation of outer handle 20, otherwise the defect that check mechanism 30 cannot be braked can be caused.
Further, in order to avoid reduction torsion spring 32 produces axial float in installation site, preferred support 31 is provided with the first draw-in groove 315, and brake block 33 is provided with the second draw-in groove, first torque arm 321 of reduction torsion spring 323 is located in the first draw-in groove 315, and the second torque arm 322 of reduction torsion spring 32 is located in the second draw-in groove.This structure limits the axial displacement of reduction torsion spring 32, ensure that the stability of its work.
Brake assembly provided by the invention, in order to increase stiffness by itself and the intensity of support 31, preferably on support 31, be provided with reinforcing rib 313, reinforcing rib 313 is preferably set to bar shaped muscle, and processing technology is simple.And more preferably, reinforcing rib 313 is distributed with multiple along the circumference of support 31, so that reinforced support 31 is at the bulk strength of self circumference, avoid the support 31 of thin wall construction that fracture or distortion occur.
Brake assembly provided by the invention, support 31 is preferably integral structure, integrated injection molding, and processing technology is simple, low cost of manufacture.
Automobile provided by the invention comprises the brake assembly of arrangements for automotive doors, and this brake assembly is the brake assembly described in above-mentioned either a program, and because this brake assembly has above-mentioned technique effect, the automobile comprising this brake assembly also should have identical technique effect.
Although the present invention is described in conjunction with above embodiment, but the present invention is not limited to above embodiment, and just by the restriction of claim, this area common technique personnel can easily modify to it and change, but do not leave essential idea of the present invention and scope.
