Description

Supporting head structure for supporting rod of front cover of automobile

Technical Field

The utility model belongs to the technical field of car bonnet bracing piece technique and specifically relates to a support head structure for car bonnet bracing piece is related to.

Background

When the supporting rod props up the front cover of the automobile, a plastic head is used at the front end of the supporting rod in order to prevent the contact part of the rod and the front cover from being damaged. In the prior art, a plastic head is arranged on a support rod, and the plastic head is not easy to fall off, and the head needs to be pier on the rod; in order to ensure that the plastic head is not easy to rotate in the central direction of the rod, a boss needs to be punched on the rod and clamped with the plastic head so as to be difficult to rotate, so that the production processes of the rod and the plastic head are more, the structure of a product is complex, and unqualified parts are easy to produce. Meanwhile, the two plastic heads need to be installed in a size matching mode, the size requirement on the parts is high, the installation is difficult when the parts are tightly matched, the parts cannot be tightly clamped when the parts are loosely matched, and the anti-falling and rotating force values of the plastic heads are small. The plastic head is produced by high-temperature injection molding, the surface size is reduced in the cooling process, and the size is unstable. There are cases where mounting is difficult and the clamping is not tight in actual assembly. Therefore, it is desirable to design a supporting head structure for a front cover supporting rod of an automobile to solve the above problems.

Disclosure of Invention

The utility model discloses an overcome not enough among the prior art, provide a support head structure for car bonnet bracing piece, it is high to have production efficiency, simple structure, and the production percent of pass is high, connects advantages such as more stable.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a support first structure for vapour vehicle bonnet bracing piece, includes bracing piece body and supports first body, be equipped with the opening structure on the lateral wall of bracing piece body, the one end embedding of bracing piece body supports first this internal and fixed with supporting first body, supports and is equipped with on the first body and prevents changeing protrudingly with opening structure adaptation.

In the technical scheme, one end of the supporting rod body and the supporting head body are molded through a metal insert injection molding process through an embedded structure, and compared with the method that a plastic head is produced and then installed on a rod, and the plastic head is directly injected and molded on the supporting rod, the production is simple, the production process is few, and the production efficiency is high; the structure is simpler, and the production qualification rate is high; the falling force and the rotating force of the plastic head can be higher by arranging the notch structure, and the plastic head is at least twice of the product assembled currently.

Preferably, one end of the support rod body and the support head body are of a metal insert injection molding structure.

Preferably, the number of the opening structures is two, the two opening structures are arranged on the side wall of the supporting rod body in a back-to-back mode, and the anti-rotation protrusions correspond to the opening structures one to one. The structure can increase the joint strength of bracing piece body and support head body, and two opening structures set up dorsad, can reduce bracing piece body intensity decline volume, increase the power of droing and the revolving force that needs simultaneously.

Preferably, the support head body comprises a connecting part connected with the support head body, a limiting part used for limiting the falling of the front cover and an anti-falling part used for preventing the falling, and a limiting ring groove is arranged between the limiting part and the anti-falling part. The structure makes the support head body can stretch into the positioning hole on the front cover to support the front cover, and the limiting ring groove and the anti-drop part can prevent the front cover from dropping from the positioning hole in the supporting process.

Preferably, the limiting ring groove is of a vertically symmetrical structure, and the anti-falling part is of a vertically symmetrical structure. The structure can further increase the anticreep ability, even the bracing piece body moves upwards, also can make the spacing annular card of upside go into, avoids the mistake to bump and leads to droing.

Preferably, the retaining part is of a conical structure, and the dimension of the retaining part on the side close to the limit ring groove is larger than the dimension of the retaining part on the side far away from the limit ring groove. The structure is convenient for the anti-falling part to extend into the positioning hole on the front cover.

Preferably, a counter bore is arranged on the end face of one end, away from the limiting ring groove, of the anti-falling part. The structure can reduce the weight of the support head body.

The utility model has the advantages that: (1) the production is simple, the production procedures are few, and the production efficiency is high; (2) the structure is simpler, and the production qualification rate is high; (3) the falling force and the rotating force of the plastic head can be higher by arranging the notch structure, and the plastic head is at least twice of the product of the existing assembly.
