Description

Technical Field

[0001] This utility model belongs to the technical field of windshield wiper bushings. Specifically, this utility model relates to a matching mechanism for the output bushing of a vehicle front windshield wiper. Background Technology

[0002] Currently, my country's automotive industry is developing rapidly, with many new car manufacturers entering the commercial vehicle and passenger vehicle markets. While improving the competitiveness of the whole vehicle, the pressure on the product strength of parts is also increasing. MINI truck models mostly use single wiper arms for their windshield wipers. Due to their small body size, the arrangement of the wiper output shaft needs to be on the same plane as the glass mounting surface. The traditional wiper output shaft sleeve mounting surface is flat and is not suitable for glass mounting surfaces with a curvature radius of 2000-8000mm.

[0003] A patent specification published on September 19, 2023, with patent number 202111596820.8, discloses a waterproof structure for a car rear wiper motor, including a motor housing, a gearbox housing, a mounting plate, and a cover plate. A positioning boss is provided at one end of the gearbox housing connected to the motor housing. A first sealing ring is provided between the gearbox housing and the motor housing. One end of the gearbox housing is fixedly connected to the cover plate. A first sealing gasket is formed by secondary injection molding on the cover plate, positioning the first sealing gasket between the cover plate and the gearbox housing. A hollow cylinder for ventilation is provided on the gearbox housing. An arc-shaped retaining ring is provided on the cover plate surrounding the outer circumference of the hollow cylinder, with the opening of the retaining ring opposite to the direction of water splashing in. A second sealing gasket is formed by secondary injection molding on the mounting plate. The other end of the gearbox housing is fixedly connected to the mounting plate, positioning the second sealing gasket between the mounting plate and the gearbox housing. An axially extending bushing is provided on the end face of the mounting plate. An output shaft slides through the bushing via a bearing, extending from the bushing to connect to the wiper.

[0004] In the existing technology, bushings are generally directly installed on the vehicle glass mounting surface to facilitate the subsequent installation of wipers and their use with the glass. However, since the glass mounting surface has a certain curvature and the surface of the glass mounting surface requires a certain manufacturing precision, the mounting surface of the bushing needs to undergo additional processes to adjust the curvature and manufacturing precision. Utility Model Content

[0005] The present invention aims to provide a simple and inexpensive matching mechanism for the output shaft sleeve of a vehicle front wiper.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a matching mechanism for a vehicle front wiper output bushing, including a mounting boss, the bushing being disposed on the mounting boss, the bushing passing through the mounting boss, the mounting boss being installed on a vehicle, and the mounting boss being provided with pins, the pins being distributed in a triangular pattern on the mounting boss.

[0007] The mounting boss is triangular in shape.

[0008] The three corners of the mounting boss are rounded.

[0009] The mounting boss is provided with an upper truncated cone and a lower truncated cone, which are located on both sides of the mounting boss, and the pin passes through the upper truncated cone and the lower truncated cone.

[0010] The bushing is inclined relative to the mounting boss.

[0011] A support plate is provided between the bushing and the mounting boss.

[0012] The technical effect of this utility model is that by making corresponding mounting bosses on the output shaft sleeve, the manufacturing precision of the entire output shaft sleeve mounting surface is reduced, thereby achieving the goal of reducing complex process input.

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0019] Please see Figure 1-3A matching mechanism for a vehicle front wiper output bushing includes a mounting boss 1, a bushing 2 disposed on the mounting boss 1, the bushing 2 passing through the mounting boss 1, the mounting boss 1 being mounted on a vehicle, and pins 3 disposed on the mounting boss 1 in a triangular arrangement. By placing the bushing 2 on the mounting boss 1 and fixing it to the vehicle frame using the mounting boss 1, the mounting boss 1 facilitates the transition and easy fixing to the vehicle. This effectively reduces the manufacturing precision of the entire bushing 2 mounting surface, eliminating the need to adjust it according to the precision of the glass mounting surface. Furthermore, since the glass mounting surface has a certain curvature, after the transition through the mounting boss 1, the mounting surface of the bushing 2 does not need to be adjusted according to the curvature of the glass mounting surface, further reducing production costs and achieving the goal of reducing complex process inputs. The mounting boss 1 is fixed to the vehicle by the pins 3, and the triangular arrangement stabilizes the mounting boss 1, reducing shaking during vehicle use.

[0020] The mounting boss 1 is triangular; the triangular structure is more stable, improves the overall strength of the mounting boss 1, and reduces the occurrence of corner breakage.

[0021] The three corners of the mounting boss 1 are rounded; rounding can effectively reduce structural damage caused by sharp corners, and also avoid injury to workers from sharp corners.

[0022] The mounting boss 1 is provided with an upper truncated cone 4 and a lower truncated cone 5, which are located on both sides of the mounting boss 1. The pin 3 passes through the upper truncated cone 4 and the lower truncated cone 5. The upper truncated cone 4 and the lower truncated cone 5 strengthen the strength of the pin 3 mounting point. Due to the vibration during vehicle use, there is torsional shear between the pin 3 and the mounting boss 1. This design reduces the risk of pin 3 breakage by increasing the contact surface between the pin 3 and the mounting structure, and also reduces the occurrence of cracks caused by compression on the mounting boss 1.

[0023] The bushing 2 is inclined relative to the mounting boss 1; the inclination of the bushing 2 can be used to adapt to the curvature of the glass mounting surface.

[0024] A support plate 6 is provided between the bushing 2 and the mounting boss 1; since the end of the bushing 2 protrudes outward, the support plate 6 is provided to improve the bushing 2's resistance to breakage and reduce the risk of breakage.

[0025] The technical effect of this utility model is that by making a corresponding mounting boss 1 on the output shaft sleeve 2, the manufacturing precision of the entire mounting surface of the output shaft sleeve 2 is reduced, thereby achieving the goal of reducing complex process input.

[0026] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
