Technical Field

[0001] This utility model relates to the field of windshield wiper technology, and in particular to a quick-release windshield wiper for mini cars. Background Technology

[0002] In today's diversified transportation landscape, mini-cars like the "old man's car" are popular among the elderly and short-distance travelers due to their compact size, affordability, and ease of operation, resulting in a continuous increase in their ownership. However, the traditional windshield wipers they are equipped with are increasingly showing their shortcomings and failing to meet actual usage needs.

[0003] Initially, to control costs, the windshield wipers installed in these low-speed electric vehicles ("older cars") mostly followed a simple design approach. In terms of installation, they generally used welding and bolting – connections that were either non-removable or extremely complex to disassemble. Once the wiper blades aged, the wiping effect deteriorated, or critical components such as the motor failed and required complete replacement, car owners had to go to professional repair shops, spending a significant amount of time waiting in line for professional assistance. Repair technicians also had to use wrenches, screwdrivers, and other tools to painstakingly disassemble numerous disassembled parts, a complicated and tedious process that incurred high labor and material costs, causing great inconvenience to car owners and disrupting their daily commutes.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] like Figures 1-10 As shown, the present invention proposes a quick-release windshield wiper for a microcar, which mainly includes a mounting arm 3, a connector 4 at the rear of which is used to fix it to the drive components inside the vehicle. A connecting block 30 is provided below the top of the mounting arm 3, on which a detachable wiper frame 1 is provided. A wiper blade 2 is provided at the bottom of the wiper frame 1.

[0026] A movable block 10 is provided at the top center of the wiper bracket 1. A top rod 11 is vertically provided at the top of the movable block 10, and its top firmly supports the top fixing plate 12. A pair of positioning holes 13 are provided on the fixing plate 12.

[0027] The connecting block 30 has a rotating groove 33 inside, and a slot 31 that communicates with the rotating groove 33 is opened at its bottom. A pair of positioning holes 32 are symmetrically opened on the wall. A mounting shell 34 is provided on one side of the connecting block 30, and a sliding plate 35 is movably placed inside it. A protruding hole 37 is opened on it. Several tension springs 36 are inside the mounting shell 34. A pull rod 38 is provided on the other side of the sliding plate 35. The pull rod 38 extends out of the outside of the mounting shell 34 for easy manual operation by the operator.

[0028] The U-shaped fixing rod 39 is made of high-strength alloy material, with good toughness and corrosion resistance. It is precisely inserted into the connecting block 30, with both ends passing directly through the positioning holes 32 and protruding into the predetermined position inside the mounting shell 34. The end wall is symmetrically provided with slots 310; several reinforcing ribs 5 are cleverly added between the mounting arm 3 and the connecting block 30.

[0029] During actual installation, the operator pulls the lever 38 in sequence, drives the sliding plate 35 to move and unlock the U-shaped fixing rod 39, inserts the fixing plate 12, rotates the wiper bracket 1 until the positioning hole 13 coincides with the insertion hole, then inserts the U-shaped fixing rod 39 back, and releases it to reset and fix it with the help of the tension spring 36. This efficiently completes the installation and removal of the wiper bracket 1, which is flexible and practical and meets the needs of diverse scenarios.

[0030] During installation, first firmly pull the lever 38 by hand and slowly and evenly pull it outward. After the lever 38 is under force, it will smoothly drive the sliding plate 35 connected to it to move to one side within the mounting shell 34. As the sliding plate 35 moves, the smaller diameter opening of the protrusion 37 that was originally stuck in the slot 310 gradually moves out of the slot 310 until both ends of the U-shaped fixing rod 39 are located in the larger diameter opening of the protrusion 37. At this moment, the U-shaped fixing rod 39 is successfully unlocked and can be easily pulled out from the connecting block 30.

[0031] Next, pick up the wiper arm 1, align the fixing plate 12 with the slot 31 and insert it vertically and slowly until the fixing plate 12 is placed in the rotating groove 33. Then, rotate the wiper arm 1 smoothly by 90 degrees. When the wiper arm 1 rotates, it will drive the fixing plate 12 to rotate 90 degrees synchronously in the rotating groove 33. At this time, the two positioning holes 13 are perfectly aligned with the two positioning insertion holes 32.

[0032] Next, pick up the U-shaped fixing rod 39, align it with the positioning hole 32, and insert it straight in, so that it passes through the positioning hole 13 in sequence, and then steadily passes out from the two positioning holes 32 on the other side of the connecting block 30. After the U-shaped fixing rod 39 is installed in place, release the tightly pulled rod 38. At this moment, the elastic force accumulated by the tension spring 36 is released instantly, pulling the sliding plate 35 to quickly and smoothly return to its original position. As the sliding plate 35 returns to its original position, the smaller diameter opening of the protrusion 37 accurately fits into the two slots 310, and all components are firmly fixed. The wiper is then installed.
