Description

A kind of automobile door stopper

Technical field

The utility model belongs to technical field of automobile parts, is specifically related to a kind of car door and uses stop.

Background technology

Automobile door stopper is to connect car door and the indispensable parts of vehicle body, mainly plays the effect of car door enable possition, location.Because the use of automobile, the environment of parking difference have dust often and invade in the stop, cause stop operation work plane to become coarse, produce operation noise and disabler; And the influence of external factor such as dust will cause some to adopt the stop of metal cases and metal construction the metal erosion phenomenon to occur, thereby causes that the stop function lost efficacy gradually and apparent disappearance.

Summary of the invention

The purpose of the utility model provides a kind of car door and uses stop, and it is simple in structure, good dustproof effect, and can reduce abnormal sound and noise.

For realizing above-mentioned purpose; The utility model has adopted following technical scheme: a kind of automobile door stopper; Comprise housing and the position limit arm that in housing, passes; Be provided with the position-limit mechanism that is fastened on the position limit arm in the said housing, the hinged end of said position limit arm passes position-limit mechanism and stretches out the outside at housing, and hinged end stretches out in the termination of hull outside portion and support hinged; End away from hinged end of position limit arm is set to stop end; Said housing is an injection-moulded housing.

The utility model can also be able to further realization in the following manner:

Said position-limit mechanism comprises the limit spring that is arranged in the housing; Limit spring is provided with slide block near an end of position limit arm; Said limit spring and slide block are formed a position-limiting unit; Said position-limiting unit branch is located at the both sides of position limit arm, and the elastic force direction of limit spring makes the head of slide block of each position-limiting unit all be pressed against on the position limit arm, and the head of said slide block and position limit arm constitute and be slidingly matched; Said position limit arm is provided with limiting section or the stopper slot that matches with slider head.

Said position limit arm comprises strip or shaft-like iron core, and the outside of said iron core is provided with iron core is wrapped in plastic body wherein, to prolong the application life of position limit arm.

Side towards the position limit arm hinged end of said housing is covered with metal cover board, and the plate face that said metal cover board deviates from housing one side is provided with dust-proof cushion, is equipped with the hole that supplies position limit arm to pass on said metal cover board and the dust-proof cushion.

The caoutchouc elasticity parts of said dust-proof cushion for when closing of the door, fitting tightly with car door inside panel beating.

The beneficial effect of the utility model is:

1, the housing in the utility model is a moulding, thereby has greatly reduced the possibility of being corroded, and has guaranteed promptly that also housing can normal and stable operation.

2, the utility model also is provided with dust-proof cushion in the outside of metal cover board; Dust-proof cushion uses rubber elastic material to process; Then dust-proof cushion, metal cover board and injection-moulded housing three cooperate; Can prevent effectively that dust gets in the car door inner chamber in the automobile use, and then stop dust to get in the stop effectively; Alleviated because of dust gets into the plastic body of position limit arm cause and the excessive wear of slide block, optimized the overall performance of stop; The structural strength and the impact resistance of stop have also been increased simultaneously.

The specific embodiment

As shown in Figure 1; A kind of automobile door stopper; The position limit arm 20 that comprises housing 10 and in housing 10, pass; Be provided with the position-limit mechanism that is fastened on the position limit arm 20 in the said housing 10, the hinged end of said position limit arm 20 passes position-limit mechanism and stretches out in the outside of housing 10, and hinged end stretches out in the termination portion in housing 10 outsides and support 30 hinged; End away from hinged end of position limit arm 20 is set to stop end; Said housing 10 is an injection-moulded housing.

Said position-limit mechanism comprises the limit spring 11 that is arranged in the housing 10; Limit spring 11 is provided with slide block 12 near an end of position limit arm 20; Said limit spring 11 is formed a position-limiting unit with slide block 12; Said position-limiting unit branch is located at the both sides of position limit arm 20, and the elastic force direction of limit spring 11 makes the head of slide block 12 of each position-limiting unit all be pressed against on the position limit arm 20, and the head of said slide block 12 and position limit arm 20 constitute and be slidingly matched; Said position limit arm 20 is provided with limiting section or the stopper slot that matches with slide block 12 heads.

Said limit spring 11 is also promptly compressed spring.

Further, said position limit arm 20 comprises strip or shaft-like iron core 21, and the outside of said iron core 21 is provided with iron core 21 is wrapped in plastic body 22 wherein.

As shown in Figure 1; Side towards position limit arm 20 hinged ends of said housing 10 is covered with metal cover board 60; The plate face that said metal cover board 60 deviates from housing 10 1 sides is provided with dust-proof cushion 50, is equipped with the hole that supplies position limit arm 20 to pass on said metal cover board 60 and the dust-proof cushion 50.

The caoutchouc elasticity parts of said dust-proof cushion 50 for when closing of the door, fitting tightly with car door inside panel beating.

Below in conjunction with Fig. 1 the utility model is further specified:

The whole housing parts of this automobile door stopper is made up of injection-moulded housing 10, dust-proof cushion 50, metal cover board 60, limit spring 11 and slide block 12.Limit spring 11, slide block 12 are loaded onto in oiling in housing 10 earlier then, press metal cover board 60 with equipment again, are stained with dust-proof cushion 50 at last.Since housing 10 be injection moulding and injected grease, make limit spring 11 combine with non-metal surfaces, avoided the abnormal sound generation of metal and Metal Contact, and internal lubrication is better; Dust-proof cushion 50 can stop dust to get into housing 10 inside effectively in addition; This frame mode of the utility model can reduce the occurrence probability of stop abnormal sound effectively.

The outside of the whole housing parts of this automobile door stopper is made up of injection-moulded housing 10 and the metal cover board 60 that is pasted with dust-proof cushion 50; This combining structure intensity is high, strong shock resistance.Cooperate suitable limit spring 11, can realize big moment.

As shown in Figure 1; This automobile door stopper is provided with stop mechanism in the stop end of stop; Stop mechanism is made up of buffer stopper 70, metal catch 80 and pin 90; Earlier be contained in the stop end of position limit arm 20 to buffer stopper 70 and metal catch 80 respectively, insert pin 90 in the hole of position limit arm 20 ends then away from support 30, slightly fixing pin 90 piers on forcing press at last.This stop mechanism can play spacing and effect backstop when stop is worked effectively, and especially when car door was crossed out, buffer stopper 70 can play decompression and the effect of receiving the momentum ability, thereby prolonged the application life of stop.

In this automobile door stopper; Support 30 is to form through rivet 23 riveted joints that can lubricate with position limit arm 20 and lining 24; Owing between rivet 23 and position limit arm 20, be provided with lining 24; Rivet 23 in the utility model has adopted self-lubricating material simultaneously, thereby makes that the lubrication state of rivet 23 riveted joints place is better.Usually car in use; Because the car door sinkage can appear in the deadweight of car door; And support 30 is fixed on and can not moves on the vehicle body; Therefore this syndeton of the utility model medium-height trestle 30 and position limit arm 20 high lubricating effect not only, and can effectively avoid check bracket 30 and position limit arm 20 that dry friction take place, avoid the generation of noise and abnormal sound.
