Abstract

The utility model relates to an outer wrench which is installed and employed on a car door of a car, which solves the problem that an outer wrench on the car doors of a charade car and a getley car are frequently damaged. The structure is that two stand legs on a stand are respectively positioned at the outside of two opening poles which are connected with an unlatching cover, a pin axle is a long axle and is fixed on two stand legs, and a U-shaped spring is sleeved on the pin axle. The utility mode is made of metallic parts, each opening pole uses a single stand leg, which can have enough supporting intensity, and the structure is simplified, and the pin axle can be utilized to penetrate the two groups of the opening poles and the stand legs, and the U-shaped spring can be used to replace the original two springs. The acting force moment and the point of strength of the two opening poles are kept Consistent, which overcomes the shortcoming of uneven force, and avoids the phenomenon of stress concentration, and a closing piece shifting fork can be promoted to keep effective opening distance in a long time, and a car door is opened more smoothly.

Description

The outer spanner of car door all-metal

The utility model relates to a kind of auto parts and components, the outer spanner of installing and using on specifically a kind of sedan door.

The charade car and the lucky car of China's production at present, outer spanner on its car door is plastics and annotates part, its structure is to be installed with and to open two easing levers that lid joins in support, each easing lever joins by a bearing pin and two rack legs that are positioned at each easing lever both sides at the support rear side respectively, the spring of one of each socket chucking easing lever on two bearing pins, the cradle back two ends be fixed with fastening outside the nut of spanner.Pull and open lid, easing lever rotates and presses down around bearing pin under the supporting role of rack leg and bearing pin, drives shift fork and stirs lock dog, thereby open car door.Because car has small amount of moisture and enters in the car door when flushing and after raining, and lock dog and shift fork are got rusty, cause certain resistance thereby open car door for outer spanner, and effective unlatching distance of lock dog shift fork is changed gradually.Finally cause the situation that needs just to open car door with the unlatching lid of pulling outer spanner energetically to occur.Owing to overexert, rack leg or easing lever on usually can the outer spanner of switch out cause the damage of outer spanner, thereby have influenced the normal use of car.This situation almost appears on each Xiali and the lucky car, it serves to show the seriousness of problem.Analyze the place of the crux of the problem of finding out of also being not difficult from the outer spanner making and the structure of present use.Its reason is: the one, and each parts of outer spanner adopt plastics to annotate system and form, and its intensity is not high.The 2nd, because usefulness is Plastic Parts,, will adopt each easing lever to rely on the double bracket leg to connect the version that supports for strengthening supporting role.Because it is coaxial that two groups of easing levers and rack leg are difficult to guarantee, so also just have to use two to connect bearing pins and two garter springs.Because two bearing pins are separated from each other, the elastic force of two springs can not guarantee in full accord again, just is difficult to be consistent so two easing levers are pulled the applied moment and the acting point of lock dog shift fork, occurs focal point of stress thus.Because car door opening is frequent, the fatigue resistance of focal point of stress is reduced, finally cause the generation of crack conditions.

The purpose of this utility model just provides the outer spanner of a kind of car door all-metal rational in infrastructure, that can use for a long time, to overcome the deficiency of existing apparatus, eliminates the focal point of stress of outer spanner, prolongs the service life of outer spanner.

The utility model is achieved in that and is installed with and opens two easing levers that lid joins in support, easing lever joins by the rack leg of bearing pin and support rear side, socket spring on the bearing pin, the cradle back two ends are fixed with fastening connection piece, and institute's improvements are that rack leg has two, lay respectively at the outside of two easing levers, bearing pin is a major axis, is fixed on the two stands leg, and the spring of socket is for tightening the U type spring of two stands leg simultaneously on bearing pin.

The utility model is owing to adopt all-metal material to make, and fatigue resistance obviously is better than Plastic Parts.Owing to be to make of metal piece, each easing lever uses single rack leg promptly to have enough support strengths, so saved two rack legs on support simultaneously.And, replace two original springs with a U type spring because the simplification of this structure just can utilize a bearing pin to run through two groups of easing levers and rack leg.So just can guarantee the applied moment of two easing levers and the conformability of acting point, overcome the defective of two groups of easing levers of original device and rack leg unbalance stress.The stress concentration phenomenon that this had both been avoided on easing lever or rack leg has improved the action effect of easing lever to the lock dog shift fork again, and the unlatching distance of impelling the lock dog shift fork to remain valid for a long time makes car door opening more smooth.Through test, with 200 kilograms of powerful unlatchings 300 times/minute, the no any variation phenomenon of this device.In addition, outer spanner adopts metal piece to make, and outward appearance can adopt electroplating technology, has also improved the decorative effect to car.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is front appearance figure of the present utility model.

Fig. 2 is a backsight structural representation of the present utility model.

Among Fig. 1, still the shape with original outer spanner is identical for the outer shape of unlatching lid 1 of the present utility model and support 2, so that match with the car door of existing Xiali and lucky car.Among Fig. 2, there are two easing levers 5 to pass, a rack leg 4 and support 2 weld togethers are respectively arranged on easing lever 5 both sides at support 2 rear portions.Mono-bearing pin 7 runs through two easing levers 5 and rack leg 4, and is fixed on the two stands leg 4.Socket U type spring 6 on the bearing pin 7, the two ends of spring are hook two easing levers 5 respectively.

Among Fig. 2, the fastening connection piece 3 at cradle back two ends is a bolt, the head of this bolt and support 2 weld togethers.During installation,, spin with nut from the car door inboard again, give fastening as long as, slightly one firmly can insert the connecting bore on the aligning of two bolts on the support car door.This mode has overcome coupling nut's bolt together of the outer spanner of original plastics and has found inconvenient defective accurately, makes the easier for installation, quick of outer spanner.
