Description

Technical Field

[0001] This utility model belongs to the field of wiper connector technology and relates to a multifunctional wiper connector. Background Technology

[0002] Windshield wipers, also known as wipers, wipers, or windshield wipers, are devices used to wipe away raindrops and dust adhering to the windshield of a vehicle in order to improve the driver's visibility and increase driving safety.

[0003] A search revealed a wiper connector disclosed in patent publication number CN213323011U, belonging to the field of automotive parts technology. The connector body includes a top cover and a base plate connected to the top cover. Connection holes are provided through both sides of the top cover. A first slot and a second slot are sequentially provided on the upper surface of the top cover along the width direction of the connector body. The first and second slots are symmetrically distributed along the centerline of the connector body's length direction. A first contact surface and a second contact surface are formed on the side walls of the connector body near the first and second slots, respectively. This solution has the advantage of being applicable to the installation and connection of wiper arms from various brands.

[0004] The above-disclosed solution forms a first contact surface and a second contact surface to be suitable for wiper arms of various brands. However, this method will cause the connector body to separate from the car wiper arm, which will cause the connector body to detach from the car wiper arm. Therefore, we have designed a multi-functional wiper connector. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional wiper connector to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solution: A multifunctional wiper connector, comprising a connector body, which is used for detachable connection with a wiper blade holder and a car wiper rocker arm. The connector body is provided with a bayonet, and the wiper blade holder is provided with a retaining shaft. The bayonet of the connector body and the retaining shaft of the wiper blade holder engage to form a hinge. The connector body is provided with a horizontal slot, and the car wiper rocker arm is inserted into the horizontal slot of the connector body. A limiting device is provided between the connector body and the car wiper rocker arm to prevent the car wiper rocker arm from disengaging.

[0007] In the aforementioned multifunctional wiper connector, the limiting device includes a positioning hole on the wiper arm, and an elastic cap at one end of the horizontal slot of the connector body. A protruding pin is provided on the inner wall of the elastic cap. When the wiper arm is inserted into the horizontal slot of the connector body, the protruding pin engages in the positioning hole of the wiper arm. This design ensures that, during actual manufacturing, the elastic cap has a U-shaped structure with a downward-facing notch. Guide ribs are provided on the inner walls of the two side plates of the elastic cap. These guide ribs guide the insertion of the wiper arm and ensure that the protruding pin remains engaged in the positioning hole of the wiper arm, preventing the protruding pin from loosening in the positioning hole.

[0008] In the aforementioned multi-functional wiper connector, the elastic cap and the connector body are integrated into a single structure, and a deformation groove is provided between the elastic cap and the connector body. The purpose of this design is to achieve a certain deformation effect through the deformation groove, allowing the elastic cap to be pressed down more effectively.

[0009] In the aforementioned multi-functional wiper connector, the insertion end of the automotive wiper arm has a downward and forward bent portion forming an insertion part. The front end of the horizontal slot of the connector body is provided with a recessed stepped surface, and the insertion part of the automotive wiper arm and the recessed stepped surface of the connector body abut against each other. The purpose of this design is to allow the automotive wiper arm to be quickly installed onto the connector body, and the recessed stepped surface provides better stability during installation.

[0010] In the aforementioned multi-functional wiper connector, a connecting plate is provided on the wiper blade holder, the retaining pin is assembled on the connecting plate, and the connector body has side grooves with the groove openings facing downwards. The connecting plate of the wiper blade holder is inserted into the side groove of the connector body. The connector body also has a longitudinally arranged insertion hole that penetrates the connecting plate of the wiper blade holder. This design facilitates the connection between the wiper blade holder and the connector body, ensuring a secure and stable connection while allowing the wiper blade holder a certain degree of rotation.

[0011] In the aforementioned multi-functional wiper connector, an arc-shaped reinforcing portion is provided at the edge of the insertion hole of the connector body. This design aims to enhance the mechanical strength of the insertion hole, which is used for the insertion of another type of automotive wiper rocker arm pin, ensuring stability with the automotive wiper rocker arm pin.

[0012] In the aforementioned multi-functional wiper connector, the upper surface of the connector body is provided with an observation window that communicates with a horizontal slot of the connector body. The purpose of this design is to facilitate observation of the installation status of the vehicle's wiper arm in the horizontal slot through this observation window, ensuring a more accurate and secure installation.

[0013] In the aforementioned multi-functional wiper connector, the connector body within the observation window also has symmetrically arranged locking positions on both sides, which extend downwards through the connector body. This arrangement is intended to allow for the insertion of other types of automotive wiper arm assemblies, making the connector body suitable for assemblies of various automotive wiper arms.

[0014] In the aforementioned multi-functional wiper connector, a recess is also provided on the connector body at the upper end of the locking slot. The purpose of this design is to allow space for another type of automotive wiper arm assembly, making the connector body suitable for assembling various automotive wiper arms.

[0015] In the aforementioned multi-functional wiper connector, bosses are provided on both outer walls of the connector body, with the outer walls of these bosses being higher than the outer walls of the connecting plate. The purpose of this design is to reduce the assembly gap between the wiper arm and the connector body during the assembly of the automotive wiper arm.

[0016] Compared with the prior art, the advantages of this multifunctional wiper connector are as follows: by setting a positioning hole on the car wiper arm and setting an elastic pressure cap at one end of the horizontal slot of the connector body, and setting a protruding pin on the inner wall of the elastic pressure cap, when the car wiper arm is inserted into the horizontal slot of the connector body, the protruding pin is engaged in the positioning hole of the car wiper arm. This ensures that the protruding pin is always engaged in the positioning hole of the car wiper arm, preventing the protruding pin of the car wiper arm from loosening in the positioning hole of the car wiper arm, and thus preventing the connector body from separating from the car wiper arm.
