Description

A kind of adjustable Armrest guide rail of novel plastic material structure
Technical field
The present invention relates to armrest fields, and in particular to the adjustable handrail of the novel plastic material structure of one kind is led Rail.
Background technique
Auto manufacturing flourishes at present, family car rapid proliferation, and autoist is to the comfort of automobile, operation The demands such as facilitate, dependency structure it is convenient using all proposing higher demand.Relatively conventional handrail mode be adjustable and It is fixed.Wherein fixed handrail is only capable of providing overturning, and free tune may be implemented in length direction in and adjustable handrail It is whole, more more options are brought to people, makes one more comfortable, can meet the needs of different customers, the satisfaction of customer can be improved, the knot Structure mode is more welcome and is received by customer.
Adjustable handrail is metal guide rail used in the previous structure, and there are weight weightings, and operating force is bigger than normal, is opened Or close and just start that strength is bigger than normal, and in sliding process, because being metal parts, surface polarisation is sliding, and feel is again partially light, Have that both ends power is big in this way, intermediate power problem less than normal, to people comfort is poor, operating with property is poor, therefore, the present invention is public A kind of adjustable Armrest guide rail of novel plastic material structure is opened, compared with prior art, the present invention has operating force one It causes, have no abnormal sound, lightweight and the advantages that environmental emission reduction.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of the adjustable of novel plastic material structure Integral expression Armrest guide rail, operating force consistency is difficult to protect when solving adjustable handrail sliding rail open and close campaign in the prior art The technical problems such as card, product weight are laid particular stress on, and operating comfort is difficult to control.The present invention is consistent with operating force, has no abnormal sound, light weight The advantages that change and environmental emission reduction.
The present invention is achieved by the following technical solutions:
The invention discloses a kind of adjustable Armrest guide rails of novel plastic material structure, including support on handrail Support base under seat, sliding equipment and handrail, handrail upper support seat are fixedly installed in the top of sliding equipment, and support base is solid under handrail Dingan County is loaded on the lower part of sliding equipment, and handrail upper support seat includes handrail epidermis and handrail upper skeleton, and handrail epidermis is fixedly connected In the upper surface of handrail upper skeleton, sliding equipment includes upper rail, friction plate, spring, damping block and lower guideway, upper rail sliding It is connected to the top of lower guideway, the fixed junction for being located at upper rail and lower guideway of friction plate, spring is fixedly mounted on upper rail One end between lower guideway, damping block are fixedly mounted between upper rail and lower guideway, and support base includes under handrail under handrail Skeleton.In the use process of other adjustable handrail sliding rails, there are operating force consistency when open and close campaign to be difficult to protect The problems such as card, product weight are laid particular stress on, and operating comfort is difficult to control, and this programme can be good at solving problem above.
Further, in order to enable upper rail is able to carry out with lower guideway engages, the two sides of the bottom of upper rail are provided with item Connected in star, the size of lower guideway two sides convex block correspond to the size of strip groove, and strip groove opening is oppositely arranged.
Further, in order to reduce the weight of product assembly, active response environmental emission reduction requirement, upper rail and lower guideway PP+30%LGF long glass fiber-reinforced polypropylene materials are all made of, which has high intensity, high rigidity, good impact strength, resists The features such as croop property and dimensional stability, and yield is big, cost is relatively low, and there are also good mobility, push automobile light weight The process of change.
Further, in order to enhance wearability and reduce noise, friction plate setting there are two and be set in two it is convex On block, friction plate and damping block are all made of POM material, which has endurance, creep resistance, wear-resisting, heat-resisting, impact resistance etc. excellent Good performance, and coefficient of friction is small, self-lubrication is good, and self-lubricating is that piece surface coefficient of friction is lower, is not necessarily to grease lubrication.
Further, in order to be fixedly connected with lower guideway with handrail lower skeleton, lower guideway is provided with eight mounting holes, two Fixation hole and a centre bore, handrail lower skeleton correspond to mounting hole and are provided with eight cylinders, and cylinder is fixedly welded on handrail sending down the fishbone Frame top, lower guideway and handrail lower skeleton are weldingly connected by cylinder.
Further, in order to generate locking effect in the opposite sliding of guide rail, spring is provided with no less than one, and spring is solid In fixation hole, the corner of upper surface four of damping block is provided with rectangular boss for Dingan County, and the bottom of upper rail also correspondence is set It sets there are four rectangular recess, the bottom of damping block is also set up there are two fixed round tube, and fixed round tube corresponds to fixation hole installation.
The beneficial effects of the present invention are: the invention discloses a kind of adjustable handrails of novel plastic material structure to lead Rail, upper rail using being clamped, and are fastened by clamping structure and handrail upper skeleton by screw, lower guideway by welding manner and Handrail lower skeleton tightens together, and upper rail and lower guideway are all made of PP+30%LGF long glass fiber-reinforced polypropylene materials, the material Material has the characteristics that high intensity, high rigidity, good impact strength, creep-resistant property and dimensional stability, and then upper rail is under Guide rail makes it correspond to convex block and strip groove assembles, the angle of upper surface four of damping block by two sides c-type feature on its part It falls and is provided with rectangular boss, the bottom of upper rail is also correspondingly arranged there are four rectangular recess, by spring to the square of damping block The rectangular recess locking of shape boss and upper rail provides elastic force, can withstand rectangular boss and rectangular recess, have locking effect, simultaneously Damping block boss feature limits upper rail and lower guideway moving distance, and such handrail upper skeleton applies mobile power to drive upper rail Sliding opposite with lower guideway, realizes the adjustment function of adjustable arm, and in addition upper rail and the mobile friction generated of lower guideway is Direct friction is avoided by two friction plates, because friction plate and damping block use POM material, which is wear-resisting, and is had Self-lubricating effect, such guide rail movement will not lead to the problem of related abnormal sound, and entire motion process, CONTACT WITH FRICTION is very steady, operation Power is comfortable, so that product quality is kept reliable and stable, the novel adjustable handrail sliding rail in the prior art that can solve of this experiment is opened The problems such as operating force consistency is difficult to ensure when opening closing movement, and product weight is laid particular stress on, and operating comfort is difficult to control, whole jail Gu it is durable, it is suitble to popularity.
