Description

The expansion piece of the flexible resilience in end

Technical field

The utility model belongs to automotive body structure technical field, the expansion piece of specifically a kind of flexible resilience in end.

Background technology

Automobile has become the indispensable vehicles in the life of people, and increasing people depend on vapour Car trip travelling, or even lived on caravan, people increasingly pay close attention to the structure and performance of automotive interior, sound insulation and noise reduction effect with And waterproof effect is also the protrusion factor for weighing automotive performance height.Body structure is complicated, often produces many cavity passages, These cavity passages can transmit noise that vibration produces in crew module, can also reduce vehicle waterproof effect, and expansion piece then can be compared with The problem of good solution water-stop gentle sealing.But existing expansion piece will be arranged on body structural member, it is desirable to have therewith The associated components of cooperation can complete a kind of A posts mentioned in assembling, such as Application No. 201320630210.X Chinese patent The seal noise insulation structure of front end, expansion piece therein need to be used in combination with supporting plate and metal mounting plate, can just be assembled to vapour On car gusset.

The content of the invention

The purpose of this utility model be to provide it is a kind of be easily assembled, the expansion for the flexible resilience in end that water resistance is good Piece.

A kind of expansion piece of the flexible resilience in end, including top, main body and end, the top is by rotatable head Constituted with fixed embedded division, the top is integrally connected with the main body, the end is integrally connected with the main body.

The utility model 1) using the top of reduction, rotatable head and fixed embedded division are formed, is entered in expansion piece Luggage timing, the top of expansion piece can preferably comply with the structure space of the head end complex of A column reinforcement plates and vehicle side-wall outer-plate, Rotatable head is bent, at the front end bayonet socket that fixed embedded division is loaded to A column reinforcement plates, the rotatable head after installing Automatic rebounding resets, and will not damage expansion piece because vehicle side-wall outer-plate structure is excessively complicated during dress side-wall outer-plate, or because swollen Swollen chip architecture is fixed and influences the assembling of side-wall outer-plate；2) when the automobile assembled is behind high -temperature workshop, expansion piece foaming will Cavities seals between side-wall outer-plate and A column reinforcement plates, play a part of waterproof, while also having preferable soundproof effect.

Further, Weakening treatment is passed through on the rotatable head, and the rotatable head includes thinner neck With the main body of sheet, the neck is integrally connected with the top.Thinner neck is connected with the top of expansion piece, while thinner Neck for sheet main body do rotation support, when the main body of sheet encounters the harder part of vehicle side when mounted, can send out Raw rotation.

Further, it is provided with a groove on the neck.The groove can make the head of rotation be easier to rotate, more carefully Neck it is not easy to break, and for rotatable head reset certain supporting role is provided.

Further, space is left between the upper end of the embedded division of the rotatable head and the fixation.The space Setting make rotatable head-turnover easily, activity flexibly.

Further, the side of the main body is provided with buckle and neck.Buckle and neck and the automobile A column of main body add Corresponding bayonet socket and buckle phase build-in is determined on strong plate, and assembling is firm, convenient.

Further, between the end and the main body in obtuse angle.The obtuse angle causes the expansion of the flexible resilience in end The end of piece is more fitted the rear ends of A column reinforcement plates, and assembling effect is more preferable.

Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings, is easy to more clearly understand the utility model, But the utility model is not limited to following embodiments.

As depicted in figs. 1 and 2, a kind of expansion piece of the flexible resilience in end, generally there is the plates of certain flexure plane, Including top 1, main body 2 and end 3, top 1 is made up of the rotatable head 1.1 by reduction and fixed embedded division 1.2, Rotatable head 1.1 is plates in obtuse angle, rotatable head by thinner neck 1.1.1 and sheet main body 1.1.2 constitute, wherein opening up groove a 1.1.3, thinner neck 1.1.1 and fixation in thinner neck 1.1.1 centre Embedded division 1.2 is integrally formed, and a fixed gap is left on the main body 1.1.2 of sheet lower end and the top of fixed embedded division 1.2；Top End 1 is connected with the one of main body 2, and end 3 and main body 2 be integral to be connected and between the two in obtuse angle, the side of main body 2 is provided with buckle 2.1 and neck 2.2, buckle 2.1 is formed directly into the neck of A column reinforcement plates, and neck 2.2 is corresponding with the buckle on A column reinforcement plates It is fixed.As shown in Fig. 2 rotatable head 1.1 can bend 90 degree downwards on top 1, groove 1.1.3 limits rotatable head Bending degree, and the rotatable resilience of head 1.1 can be made, fixed embedded division 1.2 is not bent.

Assembling process of the present utility model is described as follows, as shown in figure 3, top 1, main body 2, end 3 together constitute end Main body 2, is caught in A column reinforcement plates 4 by the expansion piece of the flexible resilience in portion, its global shape laminating automobile A column reinforcing plate 4 first In corresponding structure, then by 90 degree of the bending downwards of the rotatable head 1.1 in top 1, fixed embedded division 1.2 is caught in A posts The front end of reinforcing plate 4, rotatable head 1.1 can gradually be set back, and end 3 is fitted the rear ends of A column reinforcement plates 4 therewith, with Vehicle side-wall outer-plate 5 is installed on the A column reinforcement plates 4 of the expansion piece equipped with the flexible resilience in end afterwards, then completes assembling.Through Cross after high temperature plant working, the expansion piece hair of the flexible resilience in the end being clipped between vehicle side-wall outer-plate 5 and A column reinforcement plates 4 Foam product becomes big several times, and the cavities seals between side-wall outer-plate 5 and A column reinforcement plates 4 are got up, the water proofing property of automobile is improved Can, the noise of automobile is also reduced simultaneously..

Above-described embodiment is only schematical, and one of ordinary skill in the art is in the utility model Under the enlightenment of the expansion piece of the flexible resilience in end, the utility model objective and scope of the claimed protection feelings are not being departed from Under condition, many forms can be also derived, these are within protection domain of the present utility model.
