[0009] Furthermore, protective sleeves are movably fitted onto the outer ends of both ends of the two spring pieces, protective sleeve heads are snapped onto both ends of the two spring pieces, and an adhesive strip is snapped between the two spring pieces.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This utility model reduces the number of parts by incorporating a blocking component, which aligns with environmental protection principles, reduces the number of potential failure points, and facilitates the installation of wiper arms of different sizes. By rotating the blocking component outward, it rotates around the second locking post, causing the locking block to move until the inner side of the locking block no longer abuts against the outer side of the wiper arm. At this point, the brush connector can be pulled. The brush connector, through the first locking post and the wiper arm connector, drives the support arm to move until the support arm no longer abuts against the inside of the wiper arm. One end of the wiper arm disengages from the brush connector from above, thus completing the wiper disassembly. The inner support length of the support arm is relatively long, enabling it to abut against wiper arms of different sizes. This design reduces the number of parts, facilitates the use of the wiper, reduces the number of potential failure points, and facilitates the installation of wiper arms of different sizes.

[0012] 2. This utility model uses a stop block to fix the spring clip, making it convenient to replace the rubber strip and improving the efficiency of the wiper. By removing one of the clipped protective heads, the rubber strip can be pulled outward. Because the stop block limits the movement of the spring clip, the rubber strip will not pull the spring clip away. At this time, the rubber strip can be taken out from between the two spring clips for replacement. This design can fix the spring clip, facilitate the replacement of the rubber strip, and improve the efficiency of the wiper.

[0013] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figs. 1-6 As shown, a U-shaped wiper arm wiper includes a brush connector 4, a first locking post 5 fixedly connected inside the brush connector 4, a wiper arm connector 6 snapped into the brush connector 4, a first locking groove 7 opened inside the wiper arm connector 6, the first locking post 5 movably sleeved inside the first locking groove 7, a second locking post 8 fixedly connected inside the wiper arm connector 6, a blocking member 9 movably installed inside the wiper arm connector 6, a second locking groove 10 opened on the inner side of the blocking member 9, and the second locking post 8 movably sleeved inside the second locking groove 10. By adopting the above technical solution, by using the first locking groove 7 and the second locking groove 10 to replace the traditional center pin and the first locking post 5 and the second locking post 8, and by merging the brush connector 4 with the outer shell, the number of parts can be reduced.

[0023] Both the first locking groove 7 and the second locking groove 10 have notches on their inner sides to facilitate the installation of the first locking post 5 and the second locking post 8 into the first locking groove 7 and the second locking groove 10, respectively.

[0024] like Figs. 1-6 As shown, a support arm 13 is fixedly connected inside the wiper arm connector 6, and a connecting wiper arm 12 is abutted on the outside of the support arm 13. A locking block 11 is fixedly connected to the inside of the blocking member 9, and the inside of the locking block 11 abuts against the connecting wiper arm 12. By adopting the above technical solution, the connecting wiper arm 12 is a component that is fixedly connected to the vehicle body in actual use.

[0025] In practice, the wiper arm 12 comes in only two sizes, the difference being the length of the lower end of the U-shaped arm.

[0026] The locking block 11 is a structure with a certain elasticity and friction, which can recover after a certain deformation. When the blocking member 9 is rotated, the blocking member 9 needs to drive the locking block 11 to deform a certain degree before disengaging from the wiper arm 12, thereby strengthening the effect of the blocking member 9 in fixing the wiper arm 12.

[0027] The outer side of the brush connector 4 has a groove, which makes it easier for the user to rotate the blocking part 9 through the groove;

[0028] When the wiper is installed, the wiper arm 12 needs to move linearly to move away from the support arm 13 and then be released from the installation. However, the blocking member 9 can block and limit the linear movement of the wiper arm 12. The blocking member 9 can only release the limiting contact of the wiper arm 12 by rotating. At the same time, the wiper arm 12 will prevent the blocking member 9 from rotating through the locking block 11. Thus, the wiper arm 12 and the blocking member 9 interfere with each other to achieve a fixed installation. The installation will not be released without the influence of external force.

[0029] like Figs. 1-6 As shown, both sides of the brush connector 4 are fixedly connected to limiting rails 15. Each limiting rail 15 is movably fitted with a spring piece 17. Each side of the spring piece 17 has a limiting slot. Two stops 16 are fixedly connected at equal intervals below the brush connector 4. The lower ends of the two stops 16 are movably installed in the two limiting slots. By adopting the above technical solution, the limiting rails 15 can limit the spring pieces 17 to move only along the direction of the spring pieces 17.

[0030] like Figs. 1-2 As shown, a protective sleeve 2 is movably sleeved on both ends of the two spring pieces 17, a protective sleeve head 3 is snapped on both ends of the two spring pieces 17, and a rubber strip 1 is snapped between the two spring pieces 17. With this setting, a limiting groove is provided on the outer side of the rubber strip 1, and the spring piece 17 snaps onto the rubber strip 1 through the limiting groove, so that the rubber strip 1 can only move in a straight line to disengage from the snap of the spring piece 17.

[0031] The sheath head 3 has a limiting function, which can limit and prevent the rubber strip 1 from leaving the spring piece 17.

[0032] In use, by rotating the blocking member 9 outward, the blocking member 9 rotates around the second locking post 8 as the axis. The blocking member 9 drives the locking block 11 to move until the inner side of the locking block 11 no longer abuts against the outer side of the wiper arm 12. At this time, the brush connector 4 can be pulled. The brush connector 4 drives the support arm 13 to move through the first locking post 5 and the wiper arm connector 6 until the support arm 13 no longer abuts against the inside of the wiper arm 12. One end of the wiper arm 12 disengages from the top of the brush connector 4. At this time, the wiper can be disassembled. The inner support length of the support arm 13 is relatively long, which can abut against wiper arms 12 of different sizes.

[0033] When it is necessary to replace the rubber strip 1, remove one of the clipped protective heads 3, and then pull the rubber strip 1 outward. Because the stop block 16 limits the movement of the spring piece 17, the rubber strip 1 will not drive the spring piece 17 away. At this time, the rubber strip 1 can be taken out from between the two spring pieces 17 for replacement.

[0034] This utility model provides a U-shaped wiper arm, which solves the problems of existing U-shaped wiper arms having too many parts, making installation inconvenient, and being more prone to damage after prolonged use. There are also two sizes of wiper arms on the market, and existing wiper arms are not convenient to accommodate the installation needs of both types of wiper arms. This invention is more practical.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
