[0007] A hook plate is provided at one end of the scraper rod, and the wiper is assembled and connected with the hook plate through an accessory.

[0008] Furthermore, the accessory is provided with an axial hole for facilitating rotation around the bracket;

[0009] The accessory is provided with an offset piece, a boss is provided at the top of the offset piece, and a rib for preventing the accessory from withdrawing is provided at a top corner of one side of the boss.

[0010] Furthermore, the bracket is provided with a rotating shaft used in conjunction with the shaft hole;

[0011] The convex rib is located on a side of the boss close to the rotation axis.

[0012] Furthermore, the hook plate is provided with a receiving hole for receiving the boss.

[0013] Furthermore, the offset member is offset around its own rotation center, and the offset center of the offset member is closer to the rotation axis than the boss.

[0014] Furthermore, the hook plate is U-shaped, and is provided with a first catch and a second catch for hooking the bottom end of the accessory.

[0015] Furthermore, the lengths between the first clamping claws are equal, and the lengths between the second clamping claws are equal.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] Optimize the anti-recoil structure of the wiper attachment to increase the anti-recoil force of the wiper;

[0018] The hook plate claw is shortened to reduce the risk of claw deformation;

[0019] The hook plate claws are arranged in a symmetrical structure, which can increase the market versatility of the hook plate and the wiper, and facilitate the aftermarket car owners to replace the wipers. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1:

[0027] like Figure 1 As shown: a new type of wiper arm assembly structure, wherein the wiper 1 and the wiper arm 6 are used to remove foreign matter and rainwater on the glass, and the wiper arm 6 drives the wiper 1 to brush along the up and down direction of the glass to remove water and stains on the glass;

[0028] The wiper 1 is provided with a bracket 2 for fixing the spring sheet, the bracket 2 is provided with an accessory 4 which can rotate around the bracket, the end of the fixed spring sheet is connected with the buckle of the bracket 2, a scraper rod 5 is provided at one end of the scraper arm 6, the scraper rod 5 is provided with a hook plate 3, and the wiper 1 is assembled to the hook plate 3 through the accessory 4.

[0029] like Figure 2As shown: an axial hole that can rotate around the bracket rotation axis 21 is provided on the attachment 4, a deflecting member 10 that can deflect is provided on the attachment 4, a protruding boss 8 is provided on the deflecting member 10, and a convex rib 9 is provided on the side of the boss 8, wherein the convex rib 9 is provided on the side of the boss 8 close to the rotation axis and near the intersection of the side and the top of the boss 8;

[0030] When the accessory 4 is assembled on the upper plane of the hook plate 3 , the convex rib 9 plays an additional role in preventing the accessory 4 from being withdrawn, thereby greatly increasing the withdrawal prevention force of the wiper 1 .

[0031] like Figure 3 As shown: a receiving hole is provided on the hook plate 3, which is used to accommodate the boss 8 on the accessory 4, and a convex rib 9 is provided on the boss 8 structure. When the accessory is assembled on the hook plate 3, the boss 8 enters into the receiving hole of the hook plate 3. At this time, the convex rib 9 is above the upper plane of the hook plate 3, so that when the wiper 1 is withdrawn in the direction of pulling out the hook plate, the convex rib 9 will resist the side wall of the hole on the upper plane of the hook plate 3, thereby generating a stopping force.

[0032] like Figure 4 As shown: the accessory 4 is assembled with the bracket rotation axis 21 through the shaft hole, wherein the offset member 41 on the accessory 4 is offset around the rotation center of the offset member, and the rotation center of the offset member 41 is closer to the bracket rotation axis 21 than the boss 8 on the offset member 41.

[0033] like Figure 5-6 As shown: the hook plate 3 is a U-shaped structure, and the hook plate 3 is provided with a receiving hole for receiving the accessory boss 8 and a first clamping claw 111 and a second clamping claw 113 for hooking the bottom end of the accessory 4;

[0034] At least one pair of claws 111 and one pair of claws 113 are provided, which are respectively provided on two side surfaces of the hook plate 3. The claws 111 and the claws 113 on the two side surfaces are of equal length. After the hook plate 3 is assembled with the accessory 4, the claws 111 and the claws 113 respectively clamp the lower side of the accessory 4, so that the hook plate 3 is stable and not easy to fall off.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
