The back surface of the column B is provided with a clamping part, and the bottom plate of the coupling hook is clamped in the clamping part in a matching way. the connection mode of the coupling hook and the column B is changed into direct human clamping connection from welding connection and gluing connection by the connector of a car column B and a coupling hook, so that the case that the device investment for the welding connection and the process flow of the gluing connection increase is avoided to improve production efficiency.

Description

The connecting device of sedan B-post and hook

Technical field

The utility model relates to the connecting device of a kind of sedan B-post and hook, specifically, relates to the sedan B-post body and adopts artificial snap fit to carry out the bonded assembly device with hook.

Background technology

The automotive trim post mainly adopts the fastener direct connection with body contact at present.Fastener mostly is a gauge member, can directly purchase, and need not mould newly developed.The generally direct injection moulding of decorations post body is come out, inject at the body back side during injection moulding can and fastener bonded assembly base (BOSS), by manually the fastener end being snapped in the base (BOSS) on the decorations post, the decorations post that has installed fastener directly is pressed on the vehicle body in the cooresponding with it mounting hole site, has so just finished the assembling of decorations post with vehicle body.Sedan B-post generally is made of two parts at present, first B post body, its two be the hook since the hook position and shape special, can't direct injection moulding come out to link up with when the injection moulding body now, hook must at first be welded on the body with special-purpose device for ultrasonic welding.Make technological process increase, production efficiency reduces, and cost increases.

Novel content

The purpose of this utility model is, the connecting device of a kind of sedan B-post and hook is provided, to solve the mode that existing hook must adopt ultrasonic welding or glue to glued joint with B post body, need special-purpose device for ultrasonic welding or increase the glue adhesive technology, make technological process increase, production efficiency reduces, the technical matters that cost increases.

In order to achieve the above object, the technical solution of the utility model is as follows:

The connecting device of a kind of sedan B-post and hook, the B post back side is provided with the Access Division; The base plate coupling of hook snaps in described Access Division.

Adopt the connecting device of above-mentioned sedan B-post of the present utility model and hook, made the connection mode of linking up with B post body into the direct labor clamping by welding and splicing, avoided the equipment investment of welding and the increase of adhesive technology flow process, improved production efficiency.

Described Access Division is the clamping die cavity, and its length is half of hook length or slightly long.

For preventing that hook from oppositely skidding off, described clamping die cavity upper end is provided with barb.When clamping hook being applied certain thrust makes barb generation elastic deformation and snaps in the clamping die cavity.

Because cause the distortion of clamping die cavity top when hook and body contact easily, the opening part of described clamping die cavity is provided with the triangle reinforced rib.

Described Access Division is the clamping pin of three alternative arrangement.

Two are positioned at hook base plate upper end in the described clamping pin, and one is positioned at hook base plate lower end.So since two the clamping pin in upper end with respect to the hook can produce bigger moment clamping pin can be as far as possible little.

For preventing to link up with in transportation and assembling oppositely to deviate from, described clamping pin is provided with barb.

For increasing the intensity of clamping pin, be provided with reinforced rib behind the described clamping instep.

The specific embodiment

According to Fig. 1 to Figure 11, provide preferred embodiment of the present utility model, and described in detail below, enable to understand better function of the present utility model, characteristics.

The utility model redesigns by the body hook place to present sedan B-post, two kinds of feasible interface arrangments have been developed, make the connection mode of linking up with B post body into the direct labor clamping by welding and splicing, avoided the equipment investment of welding and the increase of adhesive technology flow process.

To shown in Figure 6, the first embodiment scheme of the present utility model is to design at B post 4 back sides to surpass half clamping die cavity 1 of hook 3 floor length as Fig. 1, and the latter half of linking up with 3 base plates snaps in the die cavity 1, and the first half of linking up with 3 base plates exposes.

At the back side of B post body 4 design clamping die cavity 1, clamping die cavity 1 directly ejects by design-calculated slanted kicking block 2, the direction that skids off of slanted kicking block 2 is the direction of being indicated among Fig. 2, the Design of length of clamping die cavity 1 becomes half of hook 3 length or omits long 1～2 millimeter, the width of clamping die cavity 1 is slightly wideer 0.1～0.5 millimeter than hook 3 width, die cavity 1 aspect ratio is linked up with slightly thick 0.1～0.3 millimeter of 3 base plate thickness, bigger clamping die cavity 1 can guarantee to link up with 3 and snap in smoothly, and it is excessive to prevent to link up with 3 double swerves again simultaneously.For preventing that linking up with 3 oppositely skids off,, when clamping, apply certain thrust and make barb 11 produce elastic deformations and snap in clamping die cavity 1 linking up with 3 at the barb 11 of clamping die cavity 1 upper end design 1～2 millimeters long.Owing to cause the distortion of die cavity 1 top when hook 3 and body contact easily, strengthen at the opening part design triangle reinforced rib of die cavity 1.

To shown in Figure 11, the second embodiment scheme of the present utility model is at three

clamping pin

5,6,7 of B post back side design as Fig. 7, the position alternative arrangement of

clamping pin

5,6,7, and three

clamping pin

5,6,7 eject respectively by three slanted kicking blocks 8,9,10.

Be provided with the

clamping pin

5,6,7 of three alternative arrangement at the back side of B post body 4, clamping

5,6,7 directly ejects along three directions among Fig. 7 by the slanted kicking block 8,9,10 of three relative motions.Clamping

5,6,7 Design of length becomes 5～8mm, clamping

5,6 width is designed to 5～10mm, the Design of length of clamping pin 7 becomes 25～35mm,

clamping pin

5,6,7 is longitudinal interval 3～5mm each other,

clamping pin

5,6,7 lateral length is designed to slightly wideer 0.1～0.5 millimeter than hook 3 width, two clamping pin 5 in three clamping pin, 6 are positioned at hook 3 base plates upper end, a clamping pin 7 is positioned at hook 3 base plate lower ends, because two clamping pin 5 in upper end, 63 can produce bigger moment with respect to hook, so clamping

5,6 can be as far as possible little, for prevent that linking up with 3 oppositely deviates from transportation and assembling, design barb 51 on clamping pin 5, when clamping by applying certain thrust and make card base 5 produce elastic deformations to snap in 3 card bases to linking up with 3.For increasing the intensity of clamping

5,6,7, can increase reinforced rib behind at clamping

5,6,7.

The front provides the description to preferred embodiment, so that any technical personnel in this area can use or utilize the utility model.To this preferred embodiment, those skilled in the art can make various modifications or conversion on the basis that does not break away from the utility model principle.Should be appreciated that these modifications or conversion do not break away from protection domain of the present utility model.
