Description

Technical Field

[0001] The utility model belongs to the technical field of automotive parts and relates to a connecting mechanism between a windshield wiper and an automotive connecting rod. Background Technique

[0002] An automotive windshield wiper is installed on the outside of the automotive windshield to wipe dust and rainwater on the outer surface of the windshield, keeping the outer surface of the windshield clean, preventing debris from affecting the driver's line of sight, and thus ensuring the safety during the driving of the vehicle. The installation of the windshield wiper requires the use of a connecting mechanism to dock with the automotive connecting rod. For example, in the prior art, a type of automotive windshield wiper disclosed in Patent No. CN202210052708.6, the skeleton of this windshield wiper further includes a mounting buckle located at the top, and a connecting groove is opened at the upper end of the mounting buckle, and the connection is made by means of a buckle. However, the disadvantages of this method are as follows:

[0003] In terms of installation; the mounting buckle and the skeleton adopt a fixed connection method, which is not convenient for disassembly, and the buckle part of the mounting buckle is prone to jamming. For this reason, we design a connecting mechanism between a windshield wiper and an automotive connecting rod. Summary of the Invention

[0004] The purpose of the utility model is to provide a connecting mechanism between a windshield wiper and an automotive connecting rod to solve the problems raised in the above background technique.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A connecting mechanism between a windshield wiper and an automotive connecting rod, including a wiper strip, a rubber strip connecting cover, a connection guiding cover, and an embedded mounting block. A cross-shaped connecting part is arranged in the middle of the steel strip of the wiper strip, and four mounting buckles are arranged on the surface of the cross-shaped connecting part. Four clamping parts are arranged at the bottom end of the rubber strip connecting cover. The wiper strip and the rubber strip connecting cover are clamped and connected through the four mounting buckles and the corresponding four clamping parts. An installation block embedding seat is arranged at the top end of the rubber strip connecting cover, and the embedded mounting block is embedded and installed at the opening groove in the middle of the installation block embedding seat;

[0006] A rotating connecting shaft is arranged in the middle of the opening groove of the installation block embedding seat. A rotating clamping seat is integrally formed at the middle part of the bottom end of the embedded mounting block. A connecting shaft assembly opening connected to the rotating connecting shaft is opened in the middle of the rotating clamping seat. A guiding cover connecting seat is installed at the top end of the embedded mounting block. A limiting column head is integrally formed at the middle part of the top end of the guiding cover connecting seat. The connection guiding cover is slidably arranged at the guiding cover connecting seat, and limiting through holes are arranged on both sides of the connection guiding cover and are connected to both ends of the limiting column head.

[0007] In the above-mentioned connecting mechanism between the windshield wiper and the vehicle linkage, an insertion head is provided at the head end of the connecting insertion cover, and a limiting tail seat is arranged at the tail end of the connecting insertion cover; a flip cover notch is arranged on the side of the top end of the insertion cover connecting seat, and the flip cover notch is correspondingly connected to the limiting tail seat. The purpose of such a setting is to facilitate the sliding insertion and installation at the insertion cover connecting seat, ensure the quickness of installation, and at the same time ensure that the sliding installation can be installed in place, so that the connection accuracy and connection strength can be guaranteed.

[0008] In the above-mentioned connecting mechanism between the windshield wiper and the vehicle linkage, a protruding installation block is arranged on one side of the bottom end of the embedded installation block, and an installation limiting groove for docking with the protruding installation block is arranged on the side of the opening groove of the installation block embedding seat. The purpose of such a setting is to make the connection between the embedded installation block and the opening groove of the installation block embedding seat more firm, prevent the separation of the installation block embedding seat and the embedded installation block during the bumpy process of the vehicle, and at the same time make the embedded installation block and the installation block embedding seat connected tightly, reducing the outward expansion of the overall volume.

[0009] In the above-mentioned connecting mechanism between the windshield wiper and the vehicle linkage, strip-shaped buckle grooves with different lengths are arranged at the top end of the connecting insertion cover. The purpose of such a setting is to facilitate the snap connection with the card cover of the vehicle component, ensuring the firmness and stability of the connection.

[0010] In the above-mentioned connecting mechanism between the windshield wiper and the vehicle linkage, scraping strip edge protection bands are arranged on both edges of the cross connecting part, and the scraping strip edge protection bands are integrally arranged with the windshield wiper strip. The purpose of such a setting is to facilitate better protection of both edges of the cross connecting part, reducing the wear of the rubber strip connecting cover on the windshield wiper strip.

[0011] Compared with the prior art, the advantages of the connecting mechanism between the windshield wiper and the vehicle linkage of the present utility model are as follows: The windshield wiper strip and the rubber strip connecting cover are connected by snap connection through four installation bayonets and corresponding four card-in parts, realizing snap connection installation, which is convenient and quick to disassemble and at the same time ensures the integrity of the windshield wiper strip, so that the performance of the windshield wiper strip will not deviate. In addition, an insertion head is provided at the head end of the connecting insertion cover, and a limiting tail seat is arranged at the tail end of the connecting insertion cover; a flip cover notch is arranged on the side of the top end of the insertion cover connecting seat and is correspondingly connected to the limiting tail seat, which is convenient for sliding insertion and installation at the insertion cover connecting seat, ensuring the quickness of installation and at the same time ensuring that the sliding installation can be installed in place, so that the connection accuracy and connection strength can be guaranteed;

[0012] By sliding the connecting insertion cover on the insertion cover connecting seat and arranging limiting through holes on both sides of the connecting insertion cover and connecting them to both ends of the limiting column head, a good limiting effect is achieved between the connecting insertion cover and the insertion cover connecting seat, and in cooperation with the flip cover notch and the limiting tail seat, the phenomenon of jamming can be avoided, improving the flexibility and variability of the connection.
