Description

Technical Field

[0001] This utility model relates to the field of automotive assembly technology, and in particular to a positioning fixture for a rear windshield wiper arm. Background Technology

[0002] The installation of the rear windshield wiper arm is one of the key steps in automotive assembly. The main arm of the wiper arm needs to be mounted on the output shaft of the motor, and the main arm and the support arm of the wiper arm need to maintain an appropriate distance from the outer surface of the glass so that when the motor drives the wiper arm to rotate back and forth, it can effectively remove rainwater from the glass.

[0003] Currently, the installation of rear windshield wiper arms relies primarily on visual inspection by installers to determine their placement. However, this method presents several technical challenges: Due to the difficulty in guaranteeing the accuracy and consistency of visual inspection, the wiper arm is often not installed precisely at the desired distance from the glass surface in one go. This necessitates post-installation testing to verify the suitability of the installation position. If the test reveals an improper placement, the wiper arm will exhibit noise, jamming, and other defects during rotation, rendering it malfunction. In this case, installers must readjust the installation position and retest until the wiper arm rotates smoothly. This increases production time, reduces installation efficiency, and results in inconsistent installation outcomes.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning fixture for rear windshield wiper arms, solving the technical problem that in the existing technology, the lack of a dedicated positioning fixture during the installation of rear windshield wiper arms leads to the need for installers to visually determine the installation position of the wiper arms, followed by physical testing to verify the suitability of the installation position. This increases production time, reduces installation efficiency, and results in poor consistency of installation results. The various technical effects of the preferred technical solution provided by this utility model are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This utility model provides a positioning fixture for a rear windshield wiper arm, including a positioning seat. The working surface of the positioning seat is provided with an installation groove, a positioning groove, and a positioning component from top to bottom. A suction cup is provided in the installation groove, and the suction cup is adsorbed and connected to the rear windshield. The positioning component is engaged with the gap between the rear windshield and the vehicle frame. The positioning groove is adapted to the wiper arm and is used to position the wiper arm so that a preset appropriate distance is maintained between the wiper arm and the rear windshield.

[0008] Preferably, the positioning groove extends through the positioning seat along the width direction of the positioning seat.

[0009] Preferably, the positioning groove includes a first positioning groove and a second positioning groove, the first positioning groove and the second positioning groove are connected, the first positioning groove is adapted to the main arm of the wiper arm, and the second positioning groove is adapted to the support arm of the wiper arm.

[0010] Preferably, a plurality of buffer pads are provided on the working surface.

[0011] Preferably, the positioning element has a triangular cross-section, and its diameter gradually decreases in the direction away from the working surface.

[0012] Preferably, the mounting groove has a plurality of first connection holes, and the suction cup has a second connection hole that matches the first connection holes, and the two are connected by fasteners.

[0013] Preferably, the mounting slot is a partially open slot.

[0014] Preferably, a gripping part is provided on the side of the positioning seat.

[0015] Preferably, the positioning seat is further provided with a weight reduction groove.

[0016] The preferred technical solution of this utility model can also produce at least the following technical effects:

[0017] This invention effectively avoids the technical problems existing in the prior art where the installation of rear windshield wiper arms lacks a dedicated positioning fixture. This leads to the need for installers to visually determine the wiper arm's position, followed by physical testing to verify suitability, increasing production time, reducing installation efficiency, and resulting in inconsistent installation results. This invention provides a positioning fixture for rear windshield wiper arms, including a positioning base. The working surface of the positioning base has, from top to bottom, a mounting groove, a positioning groove, and a positioning element. A suction cup is installed in the mounting groove and is adsorbed onto the rear windshield. The positioning element engages with the gap between the rear windshield and the vehicle frame. The positioning groove is adapted to the wiper arm for positioning it to maintain a preset appropriate distance between the wiper arm and the rear windshield. First, the main arm of the wiper arm is initially connected to the output shaft of the motor to prepare for subsequent precise positioning. Then, the wiper arm is positioned using the positioning groove of this invention to maintain a preset appropriate distance between the wiper arm and the rear windshield. Then, through the cooperation of the suction cup and the positioning component—specifically, the suction cup adsorbs onto the rear windshield, and the positioning component snaps into the rear windshield and the vehicle frame—the positioning fixture is firmly fixed to the rear windshield. After the positioning fixture is fixed and the wiper arm position is determined, the main arm of the wiper arm is finally connected to the output shaft of the motor, completing the wiper arm installation. This new positioning fixture simplifies the installation process, reduces the time spent on repeated adjustments, and quickly and accurately positions the wiper arm in one go, eliminating the need for repeated adjustments, thus improving installation efficiency. It also ensures that the wiper arm position is consistent each time it is installed, improving the consistency of the installation effect. Attached Figure Description
