Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a door stopper cover shell without a rivet structure. Background Art

[0002] With the development and popularization of automobile technology, cars have become more and more common in ordinary people's homes, and have gradually become a means of transportation for consumers to commute to get off work and travel. With the rise in fuel prices, automobile lightweighting has always been an important indicator in the automobile development process. The miniaturization and lightweight design of component structures are one of the key indicators to measure the quality of component development. The function of the door limiter is to limit the degree of door opening. On the one hand, it can limit the maximum opening of the door to prevent the door from opening too wide. On the other hand, it can prevent the door from closing automatically when the door needs to remain open.

[0003] At present, the traditional automobile limiter cover on the market is often assembled by two identical half-covers, and then connected by two rivets to fix the two half-covers. The above method has the following main disadvantages: First, the overall corrosion resistance of the limiter is affected by the rivet material and surface treatment; second, the coating on the riveted surface is easily damaged after riveting, and the corrosion resistance is reduced; third, different customers have different requirements for corrosion resistance, and the limiter supplier uses different rivets, and there are many types of rivets, which is not conducive to management and control.

[0004] For example, Chinese patent CN201720480866.6 discloses a door limiter cover, which includes a bottom shell and a cover plate, wherein the bottom shell is a hollow cuboid, one bottom surface of the cuboid is open, and the other bottom surface of the cuboid is provided with a first through hole, the size of the first through hole allows the limiter arm of the car to pass through the first through hole, and claws protrude from the edges of two opposite side walls of the cuboid respectively; the cover plate is a rectangular plate, the size of the cover plate corresponds to the size of the bottom shell, the cover plate is provided with a second through hole, the size of the second through hole allows the limiter arm of the car to pass through the second through hole, and flanges protrude from two opposite sides of the rectangular plate respectively, the flanges have mounting openings, and the size of the mounting openings corresponds to the size of the claws. The cover shell is provided with a mounting opening on the cover plate and a clamping claw on the bottom shell, and the cover plate and the bottom shell are fixedly connected by clamping the clamping claw with the mounting opening. Compared with the roll-wrapped connection between the bottom shell and the cover plate in the prior art, the volume and weight of the cover plate and the bottom shell can be reduced, and the structural design of the components is miniaturized and lightweight, while reducing the production cost. The overall structure of the stopper cover in this technical solution is still connected by rivets. The corrosion resistance of the stopper cover is affected by the rivet material and surface treatment. After riveting, the plating layer of the riveted surface is easily damaged, and the corrosion resistance is reduced.

[0005] In the prior art, the corrosion of the rivet parts on the stopper cover is solved by adding a drainage groove. For example, a drainage structure of a door stopper cover assembly disclosed in Chinese patent CN202223571978.2; the door stopper cover assembly includes a housing, a slider baffle, a slider, and a positioning spring; wherein a positioning spring is arranged between the slider baffle and the slider, and the slider baffle, the positioning spring, and the slider are arranged in a symmetrical in-line structure in the cover, and the characteristic is that the slider baffle, the slider, and the cover are all provided with drainage holes or drainage grooves. The door stopper cover assembly is provided with drainage holes or drainage grooves on its components, so that when the vehicle is used in the cold north, there is no enclosed space inside the stopper cover to cause rainwater to accumulate, thereby avoiding the phenomenon of functional failure caused by ice inside the cover. However, the stopper housing of this structure is made high, and it is easy to leave water in the drainage holes or drainage grooves on the components, and the rivets are also corroded. Utility Model Content

[0006] Purpose of the invention: In order to address the deficiencies of the prior art, the utility model provides a door limiter cover without a rivet structure, which eliminates the limiter cover structure design with a rivet structure in the prior art, thereby significantly improving the corrosion resistance of the limiter cover, and the limiter cover has a reasonable structure and is simple to manufacture, and is suitable for mass production on industrial assembly lines.

[0007] Technical solution: In order to achieve the above purpose, the utility model discloses a door limiter cover with a rivet-free structure, which includes an upper cover and a lower cover respectively mounted on the end of the limiter, the upper cover and the lower cover are positioned relative to each other, and a limiting structure is provided at the connection between the upper cover and the lower cover.

[0008] The limiting structure includes a plug-in block and a plug-in groove. The shapes of the plug-in block and the plug-in groove are adapted to each other. The plug-in block is inserted into the plug-in groove. The connection between the plug-in block and the plug-in groove is achieved through the matching connection between the plug-in block and the plug-in groove, thereby preventing the upper cover shell from rotating relative to the lower cover shell.

[0009] As a further preferred embodiment of the present invention, angles are provided between the end of the plug-in block and the two outer side surfaces of the plug-in groove, and the angles between the plug-in block and the two outer side surfaces of the plug-in groove are inclined at 20° to 30°.

[0010] As a further preferred embodiment of the present invention, the bottom of the upper cover shell is provided with a plug-in block and a plug-in groove, and the top of the lower cover shell is provided with a plug-in block and a plug-in groove, respectively. By matching the plug-in blocks and plug-in grooves of different shapes, the relative rotation of the upper cover shell and the lower cover shell is effectively prevented, thereby ensuring the stability and reliability of the connection between the upper cover shell and the lower cover shell.

[0011] As a further preferred embodiment of the present invention, the plug-in block provided at the bottom of the upper cover shell abuts against the plug-in groove on the lower cover shell, and the plug-in groove provided at the bottom of the upper cover shell abuts against the plug-in block on the lower cover shell.

[0012] As a further preferred embodiment of the present invention, the plug-in block is provided with a groove, which can be used to fix the position of the limiting structure during the secondary injection molding of the half shell assembly.

[0013] As a further preferred embodiment of the utility model, the materials of the upper cover shell and the lower cover shell are both nylon, and the outer surfaces of the joints of the upper cover shell and the lower cover shell are fixedly connected together by welding or gluing, and the upper cover shell and the lower cover shell are integrally formed by secondary injection molding. The nylon material is PA66, and the difference is that the upper cover shell and the lower cover shell are made of light-transmitting material and light-opaque material, respectively. Since the light transmittance of the two materials is different, during manufacturing, the two can be made into a whole by secondary injection molding. The difference in light transmittance allows laser welding to be used, and a weld can be generated at the assembly surface, so that the two cover shell components are welded together.

[0014] As a further preferred embodiment of the present invention, the shapes of the plug-in block and the plug-in groove are rectangular, circular, fan-shaped or other regular or irregular shapes.

[0024] The utility model will be further explained below in conjunction with the accompanying drawings.

[0025] As shown in the accompanying drawings, the vehicle door stopper cover of the rivet-free structure described in the utility model comprises an upper cover 1, a lower cover 2, a plug-in block 3, a plug-in groove 4 and a groove 5.

[0026] The shapes of the plug-in block 3 and the plug-in groove 4 are adapted to each other. The plug-in block 3 is inserted into the plug-in groove 4 to realize the connection between the upper cover shell 1 and the lower cover shell 2. By matching the plug-in blocks 3 and the plug-in grooves 4 of different shapes, the relative rotation of the upper cover shell 1 and the lower cover shell 2 is effectively prevented, thereby ensuring the stability and reliability of the connection between the upper cover shell 1 and the lower cover shell 2.

[0027] Example

[0028] The outer side surface of the plug-in block 3 and the outer side surface of the plug-in groove 4 are both vertical surfaces, and an angle is set between the two outer sides, preferably 20° to 30°. This angle can prevent the two housing components from rotating and displacing relative to each other after being plugged in.

[0029] On the lower cover shell 2, the mouth of the plug-in groove 4 is rectangular with a length-to-width ratio of 4:1. The outer side of the plug-in groove 4 is a vertical surface, parallel to the outer side of the plug-in block 3, and the ratio of depth to mouth length is 1:3. The other side of the plug-in groove 4 is a slope with an angle of 18° for easy assembly.

[0030] The outer side surface of the plug-in part 3 is a vertical surface, which cooperates with the outer side surface of the plug-in groove 4 on the corresponding cover shell body during assembly. The other side of the plug-in part 3 is a slope with an angle of 15°. There are two grooves 5 on the slope, which can be used to fix the position of the plug-in part during the secondary injection molding of the half cover shell assembly. The two grooves 5 are respectively located at 1 / 4 and 3 / 4 of the slope.

[0031] The upper shell 1 and the lower shell 2 are both made of nylon material, and the commonly used material is PA66. The difference is that the lower shell 2 is made of light-transmitting material, and the plug-in part 3 is made of opaque material. Due to the different light transmittances of the two materials, during manufacturing, the two can be made into a whole by secondary injection molding. The difference in light transmittance allows the use of laser welding, and the weld can be generated at the assembly surface, so that the two half shell components are welded together.

[0032] The above implementation is only to illustrate the technical concept and features of the utility model, and its purpose is to enable technicians familiar with the technical field to understand the content of the utility model and implement it accordingly, and it cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
