Description

A kind of plastics clamping structure
Technical field
The present invention relates to a kind of auto parts and components connection structure, specifically a kind of plastics clamping structure.
Background technique
As consumption upgrades, pursued in consumer under personalized historical background, automobile also becomes increasingly function electronics Change, technicalization and digitlization, the regional ensembles such as interior trim instrument board more and more electronic displays, touch screen etc..Traditionally, Positioning, the fixation (such as fixation of the vehicle air conditioning outlet panel on air outlet shell) of each correlated parts are all by self tapping spiral shell Nail, metal buckle or big plastic buckle realize that meet the fixing intensity requirement of each part, but these traditional fixed forms are real Existing premise is to need to reserve enough design sections to the part being mutually matched.And with the upgrading of auto electric, interior trim Part is more and more, and traditional fixed form brings many challenges to designers, i.e., how not to reduce part fixation by force Under conditions of degree, the adapted space of part is reduced, area requirement needed for increasing new parts with satisfaction, and traditional fixed form It is often difficult to meet this requirement.
Summary of the invention
The technical problem to be solved by the present invention is to, in view of the deficiencies of the prior art, provide a kind of overall structure it is compact, can The plastics clamping structure leaned on.
The technical scheme of the invention to solve the technical problem is: a kind of plastics clamping structure, including plastics system At clamping portion and stopper head, the first card slot and the second card slot, the clamping portion inlay card it is described in first card slot Stopper head plug be located in second card slot, first card slot is provided with the side of the first part, described first For the opening of card slot towards the outside of first part, second card slot is provided with the middle part of first part, Opening down, second card slot clamping portion opposite, described with first groove position of second card slot It is integrally disposed upon the side of the second part, the stopper head is integrally disposed upon the top of third part.
When assembly, the first part is installed from top to bottom, and is caught in the clamping portion on the second part on the first part In first card slot, i.e., the first part is fixed on the second part;Third part is installed from the bottom up again, is made on third part Stopper head fill in the second card slot on the first part, i.e., third part and the first part and the second part are fixed on one It rises, to complete the interlocking of the first part, the second part and third part, realizes the fixation to the first part.
The overall structure of this plastics clamping structure is compact, reliable, mutual with third part by the first part, the second part Lock realizes the fixation to the first part,, can relative to fixed structures such as tradition clampings under the premise of guaranteeing identical fixing intensity The design space of clamping structure is set to reduce one times or more.Clamping deflection when this plastics clamping structure assembles, between each part It is small, it is easier to the assembly of part;After the assembly is completed, the stopper head on third part is located at the interior of the first card slot on the first part Side has tied up the space that the first part deforms inside under external force, and withdrawal force needed for extracting the first part is made to increase greatly Add, it is thus achieved that fixedlying positioning to the first part, prevents falling off for the first part.
Preferably, be provided with limiting stand at the top of the third part, the top surface of the limiting stand and described The bottom surface contact of the side far from first card slot of first part.The design of limiting stand, convenient for assembly, while to plunger Head plays position-limiting action, prevents from causing damage parts because stopper head assembly is improper.
Preferably, the top surface of the clamping portion is inclined-plane, the bottom surface of the clamping portion is plane.By clamping portion Top surface is designed as inclined-plane, contacts to avoid clamping portion with the slot bottom of the first card slot, and the deformation for the second part after assembly is left a blank in advance Between, to play better protective effect.
Preferably, being wholely set the clamping for stretching to the slot bottom of first card slot at the top of the clamping portion Head is wholely set the outside for stretching to first part on first part on the downside of first card slot Male part, the bottom surface of the clamping portion are contacted with the top surface of the male part.Male part to the assembly of clamping portion play into The guiding role of one step, while the contact area of the second part and the first part can be increased, keep the two clamping more firm.
Preferably, the clamping joint is the clamping joint by chamfering, the stopper head is the plunger by chamfering Head, the male part are male part by chamfering, it is therefore an objective to convenient in assembling process to the second part and third part Guiding, is easily installed part.
Preferably, between being respectively provided between the two sides of the stopper head and the two sides of second card slot Gap, to reserve certain cushion space for the deformation inside of the first part under external force.
Preferably, the distance between described two sides of the second card slot are than the bottom surface of the clamping portion and described The width of contact surface between the top surface of male part is big, to meet the first part Deformation Demands inside to greatest extent.
Preferably, the distance between described two sides of the second card slot are than the bottom surface of the clamping portion and described At least big 0.3 mm of the width of contact surface between the top surface of male part, can meet the mutual of the parts such as general automobile interior decoration instrument board Lock is fixed to be needed.In practical applications, depending on part dimension difference, it is poor that corresponding size can also be specifically chosen.
Compared with prior art, the present invention has the advantage that the overall structure of plastics clamping structure disclosed by the invention It is compact, reliable, the fixation to the first part is realized by the interlocking of the first part, the second part and third part, is guaranteeing phase Under the premise of with fixing intensity, relative to tradition clamping etc. fixed structures, can make clamping structure design space reduce one times with On.When this plastics clamping structure assembles, the clamping deflection between each part is small, it is easier to the assembly of part;After the assembly is completed, Stopper head on third part is located at the inside of the first card slot on the first part, and it is past under external force to have tied up the first part The space of interior deformation greatly increases withdrawal force needed for extracting the first part, it is thus achieved that the secured fixed of the first part Position, prevents falling off for the first part.
