Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, so that those skilled in the art can better understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
The utility model provides a kind of limiting structure and has the door-open stopper of this structure, as shown in Figure 1, door-open stopper comprises a limiting structure 100 and a syndeton 500, and door-open stopper is arranged between the car door D and car body B of a car tool, to limit the opened and closed positions of car door D.
As Fig. 2 to Fig. 4 and arrange in pairs or groups as shown in Fig. 5 to Fig. 7, syndeton 500 comprises a connecting rod 5, two ends of connecting rod 5 are connected to car door D and car body B, and connecting rod 5 has and be wavy two opposite faces, and each opposite face has a connected majority recess 51 and most protuberances 52.
Limiting structure 100 comprises: a housing 1, a pair of gripper pad 2 and a pair of elastic body 3.Wherein, in housing 1, be hollow and be arranged at car door D, housing 1 can be formed by one first shell 11 and one second shell 12 combinations with one another, but not as limit, the front side (being positioned at the first shell 11) of housing 1 and rear side (being positioned at the second shell 12) also offer respectively opening 111 and another opening 121, intert for connecting rod 5 is movable.
Two gripper pads 2 are all arranged in housing 1, to be relatively held on the two relative surfaces of connecting rod 5.Each gripper pad 2 has two contacts 21, in the present embodiment, between two contacts 21 of each gripper pad 2, be also connected with a pad body 22, the bottom surface (seeing Fig. 4) of pad body 22 corresponding aforementioned connecting rod 5 opposite face and be protruding with a slippage contact site 223, two gripper pads 2 are connected to the two relative surfaces (as shown in Figure 6) of connecting rod 5 relatively with slippage contact site 223, for example, be relatively connected to two relative recesses 51 or two relative protuberances 52.Each contact 21 of each gripper pad 2 has a contact surface 211, and as shown in Figure 7, the contact surface 211 of two contacts 21 of each gripper pad 2 is contacted with respectively two opposite sides 115 (left side and right side) of housing 1.
Each contact 21 also longitudinally offers a cushion space 210, and as shown in Figure 7, cushion space 210 is positioned between the opposite side (left side or right side) of gripper pad 2 and housing 1.Thus, even if two gripper pads 2 are extruded distortion because of connecting rod 5, precisely because being fully cushioned space 210, deflection absorbs, for example: the former crushed element that should protrude towards housing 1 direction, by because stopping of housing 1 and automatically oppositely towards cushion space 210 projecting inward (thering is the self-adjusting effect of elasticity), thereby two gripper pads 2 that make to be extruded after distortion still can be successfully in the interior slippage of housing 1, user in the time opening and closing car door D by still can according to usual power execute into, smoothness while enabling to keep opening/closing door of vehicle operation, and then the life-span of lifting limiting structure 100.
Two elastic bodys 3 are all arranged in housing 1, and each elastic body 3 resiliency supported, between each gripper pad 2 and the upside and downside of housing 1, as shown in Figure 6, are lived the state of connecting rod 5 to allow two gripper pads 2 can remain on resilient clamp.
For allowing elastic body 3 in the action of elastic shrinkage and elastic stretch, still can keep being supported between the pad body 22 of gripper pad 2 and the upside of housing 1 or downside and not be shifted, its way has two, is described below.
Way one: as shown in Figure 4,5, 6, longitudinally offer most grooves 221 at the end face of pad body 22, so that elastic body 3 is at pressurized and when elastic shrinkage, one end can because be extruded, corresponding each groove 221 be extruded most protuberance (not shown), each protuberance correspondence of elastic body 3 is filled in each groove 221, so can produce locating effect.Another effect that way one is derived: originally gripper pad 2 can allow the slightly depressed deformation of end face of pad body 22 in the time of plastic ejection moulding, but because the utility model offers most grooves 221 at pad body 22 end faces, make pad body 22 attenuation, the depressed deformation amount while therefore allowing ejection formation drops to minimum.
Way two: as shown in Figure 4,5, 6, the top of two contacts 21 of each gripper pad 2 protrudes from the end face of pad body 22, and pad body 22 court are protruding with two keepers 222, between the top of two contacts 21 and two keepers 222, be encircled into certain bit space 23, an end face of elastic body 3 is positioned in the space, location 23 of gripper pad 2.
In addition, in order to reduce the frictional force between another two opposite sides (front side and rear side) of gripper pad 2 and housing 1, as Fig. 4, 5, shown in 7, two relative edges (front and back) of each contact 21 of gripper pad 2 convex with respectively one and contact rib 212, so that each contact 21 is only contacted with respectively another two opposite sides (front side and rear side) of housing 1 with two contact ribs 212, namely: between each contact 21 and housing 1, meeting contacts the existence of rib 212 because of two and is separated out to each other gap 112, 122 (seeing Fig. 7), thereby reach the object of dwindling contact area and reducing frictional force, make gripper pad 2 slippage more swimmingly, and relatively make car door D there is the effect of better switching.
In sum, the utility model has following effect compared to prior art cording: have two contacts 21 by gripper pad 2, each contact 21 also offers cushion space 210, with the deflection that allows gripper pad 2 be out of shape because pushed by connecting rod 5, can fully be cushioned space 210 absorbs, thereby the gripper pad 2 that makes to be extruded after distortion still can be successfully in the interior slippage of housing 1, the smoothness while enabling to keep car door D opening and closing operations, and then the life-span of lifting limiting structure 100.Convex with respectively contact rib 212 by contact 21 2 relative edges of gripper pad 2, so that each contact 21 is only contacted with respectively another two opposite sides (front side and rear side) of housing 1 with two contact ribs 212, thereby reach the object of dwindling contact area and reducing frictional force, make the gripper pad 2 can slippage more swimmingly in housing 1, and relatively make car door D there is the effect of better switching.
In addition, the utility model also has other effect: by offer most grooves 221 at the end face of pad body 22, or the end face that protrudes from pad body 22 and pad body 22 by the top of two contacts 21 also epirelief have two keepers 222 to be encircled into certain bit space 23, so that in the action of elastic shrinkage and elastic stretch, still keeping being supported between housing 1 and the pad body 22 of gripper pad 2, elastic body 3 is not shifted.By offer most grooves 221 at the end face of pad body 22, can also make the corresponding attenuation of pad body 22, thereby the depressed deformation amount while allowing gripper pad 2 ejection formation drops to minimum.
The above embodiment is only the preferred embodiment for absolutely proving that the utility model is lifted, and protection domain of the present utility model is not limited to this.What those skilled in the art did on the utility model basis is equal to alternative or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
