Abstract
The invention relates to an injection sealing strip combined type insert structure for an automobile threshold, which comprises an insert body and two buckles, wherein the insert body and the buckles are clamped together through clamping grooves to form a combined type insert. Two clamping grooves are formed in two ends of the insert body respectively, a clamping piece is arranged on each of two sides of the back of each buckle respectively, and the two buckles are clamped in the two clamping grooves in the two ends of the insert body through the clamping pieces. The combined insert structure with the built-in threshold injection sealing strip can improve the rigidity of the threshold injection sealing strip product so as to achieve the effects of dust prevention and noise reduction by being tightly matched with a vehicle door metal plate.
Description
Technical Field
The invention relates to the field of structural arrangement of automobile sealing strip systems, in particular to an injection sealing strip combined type insert structure.
Background
Competition in the automobile industry tends to be white, low price and high performance become key factors for selecting products by customers, the middle and high-grade automobile models which are used as profit guarantee are used, terminal selling price is continuously detected, the industry situation brings serious challenges to automobile factories, and a design scheme with low cost and high performance is a key, so that products with low cost, high performance and high reliability are particularly important to realize through system structure analysis and structure optimization during early design of an automobile sealing system.
The threshold injection sealing strip is arranged on the inner plate of the vehicle door to play the roles of dust prevention, noise reduction and the like, and the traditional threshold injection sealing strip has no insert inside due to inconsistent modeling of the metal plate structure of the vehicle door of each large host factory, so that the threshold sealing strip is arranged on the vehicle door after being arranged on the vehicle door
Very easily appear with the panel beating not laminate, the local defect of collapsing, the outward appearance is pleasing to the eye etc. leads to threshold injection sealing strip not to play dustproof, fall the sealed effect of making an uproar on the door, influences driving comfort level, in order to improve driving comfort level, thereby needs the built-in combination formula inserts structure of design development threshold injection sealing strip to promote product rigidity and reach and closely cooperate the effect of playing dustproof, falling the noise with the door panel beating.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides an automobile threshold injection sealing strip combined insert structure which is used for improving the strength, durability and appearance of a product.
In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides an automobile threshold injection sealing strip combination formula inserts structure, includes an inserts body and two buckles, inserts body and buckle pass through the draw-in groove joint and constitute combination formula inserts together.
Further, both ends are equipped with two draw-in grooves respectively above the inserts body, and every buckle both sides at the back are equipped with a joint spare respectively, and two buckles are in two draw-in grooves at this both ends of inserts through respective joint spare joint.
Furthermore, the insert body is made of PA66 and 30% glass fiber.
Further, the material of the buckle assembly is PA46.
Furthermore, the combined type insert structure for the injection sealing strip of the automobile threshold is arranged in the injection sealing strip of the automobile threshold and used for improving the rigidity of the injection sealing strip of the threshold, so that the combined type insert structure is tightly matched with a metal plate of an automobile door, and plays roles in preventing dust and reducing noise.
The invention has the beneficial effects that:
the combined insert structure with the built-in threshold injection sealing strip can improve the rigidity of the threshold injection sealing strip product so as to achieve the effects of dust prevention and noise reduction by being tightly matched with a vehicle door metal plate.
The insert body is made of PA66 and 30% glass fiber, so that the strength and rigidity of the threshold injection sealing strip product can be improved, and the bonding effect with a vehicle door sheet metal is better.
PA46 is selected as the material of the buckle, so that the buckle has certain elasticity and toughness, and the durability is improved.

FIG. 2 is a schematic view of a modular insert construction;
fig. 3 is an exploded view of the modular insert.
Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 1, the combined insert structure for the injection sealing strip of the automobile threshold is arranged in the injection sealing strip 1 of the automobile threshold, and comprises an insert body 2 and two buckles 3, wherein the insert body 2 and the buckles 3 are made of different materials, and the insert body 2 and the buckles 3 are clamped together through clamping grooves to form the combined insert.
As shown in fig. 2 and 3, two ends of the upper surface of the insert body 2 are respectively provided with two clamping grooves, two sides of the back surface of each buckle 3 are respectively provided with a clamping piece, and the two buckles 3 are clamped in the two clamping grooves at two ends of the insert body 2 through respective clamping pieces.
In order to improve the strength and rigidity of the product and keep better bonding effect with a car door sheet metal, the material of the insert body 2 is made of PA66 and 30% glass fiber, and the buckle 3 is clamped with a hole site of the car door sheet metal and is required to be repeatedly disassembled and assembled for 2-3 times without damage, so that the buckle 3 has certain elasticity and toughness, and the material of the buckle 3 is made of PA46.
The combined insert has the following functions and functions:
(1) combined body-insert-PA 66+ 30% GF. The functions are as follows: the rigidity and the strength of the injection threshold sealing strip are improved. The function is as follows: the laminating effect of the injection threshold sealing strip and the vehicle door metal plate is improved, and the dustproof and noise-proof performance is better.
(2) Modular subassemblies-snap-PA 66. The functions are as follows: the injection sealing strip is ensured to be repeatedly disassembled and assembled and is not easy to damage. The function is as follows: the sealing strip is ensured not to be separated from the car door metal plate in the door opening and closing process, and the durability is improved.
