[0019] like Figure 1 As shown, the easy-to-install wiper blade positioning assembly structure includes a steel strip back plate 1 and a wiper blade rubber strip 2 connected to the steel strip back plate 1. The steel strip back plate 1 is connected to the wiper arm through a positioning device. The positioning device includes a pad 31 with several protrusions 30 on both sides. The protrusions 30 correspond to the slots 10 in the middle of the steel strip back plate 1. A locking bracket 32 ​​is provided on the outer side of the pad 31. The bottom sides of the locking bracket 32 ​​are provided with sliding grooves 41 covering the sides of the steel strip back plate 1 and the pad 31. At least one side of the pad 31 is provided with an elastic pressing arm 51. The end of the elastic pressing arm 51 has a locking block 52. The locking block 52 cooperates with the mounting groove 42 provided on the side of the locking bracket 32. The top of the locking bracket 32 ​​is connected to the connecting cap 33 by a mounting buckle. The top of the connecting cap 33 is detachably connected to the end of the wiper arm.

[0020] Its working principle is as follows: the wiper blade 2 is connected to the steel back plate 1. The slots 10 on both sides of the middle of the steel back plate 1 are inserted into the several protrusions 30 on both sides of the pad 31 to achieve positioning of the pad 31 and the steel back plate 1. Since the pad 31 has an elastic pressing arm 51 on one side, the snap-fit ​​block 52 at its end cooperates with the mounting groove 42 on the side of the snap-fit ​​bracket 32 ​​to achieve the connection between the pad 31 and the snap-fit ​​bracket 32. The top of the snap-fit ​​bracket 32 ​​is connected to the connecting cap 33 through the mounting buckle. After the top of the connecting cap 33 is detachably connected to the end of the wiper arm, the assembly of the positioning component is completed. Compared with the general structure, the pad 31 of this patent is positioned on both sides with the steel back plate 1, providing redundant gaps for the middle insertion and installation of the wiper blade 2. It positions the blade without excessive mechanical pressure, reducing wear and damage. Secondly, the pad 31 and the snap-fit ​​bracket 32 ​​are positioned by elastic snap-fit, making installation and disassembly more convenient, use simpler, and the combined structure more compact, economical, and durable.

[0021] It should be noted that the elastic pressing arm 51 is located below the wiper, that is, the mounting groove 42 on the side of the locking bracket 32 ​​is also located below, to prevent rainwater from entering the positioning structure through the mounting groove 42; one end of the elastic pressing arm 51 is connected to the side of the pad 31, and the other end is raised on the side of the pad 31 to provide elastic pressure for the locking block 52 to enter the mounting groove (hole) 42 after being pressed down.

[0022] In the aforementioned structure that facilitates the disassembly and assembly of the wiper blade positioning assembly,

[0023] --like Figure 2 As shown, preferably, the steel strip back plate 1 consists of two parallel strips, with slots 10 respectively provided on the strips. In order to ensure balanced force and firm positioning, the slots 10 are symmetrically distributed on the two strips, forming a channel 11 between the strips. The slots 21 on both sides of the wiper blade 2 are placed in the channel 11, which can effectively support and fix the wiper blade 2.

[0024] —Furthermore, the aforementioned mounting buckle includes a horizontal shaft 61 set at the top of the locking bracket 32, and a slot 62 corresponding to the horizontal shaft 61 is set at the bottom of the connecting cap 33. The horizontal shaft 61 is pressed into the slot 62. The cross section of the horizontal shaft 61 is generally circular, and the cross section of the slot 62 is semi-circular. When pressed, it provides a certain elastic pressure to ensure that the slot 62 can contain the horizontal shaft 61.

[0025] — Preferably, the horizontal shaft 61 is connected to support plates 63 at both ends. The bottom of the support plates 63 is connected to the top of the locking bracket 32. The connecting cap 33 includes a pair of side plates 64. The side plates 64 are connected by several shafts 65. The two ends of the slot 62 are respectively connected to the side plates 64. That is, the locking bracket 32 ​​with the horizontal shaft 61 and the connecting cap 33 with the slot 62 are both hollow three-dimensional structures, which facilitates the locking of the horizontal shaft 61 and the slot 62. The side of the support plate 63 is provided with a liner 66. A cavity 67 is formed between the liner 66 and the support plate 63 for the side plates 64 to be inserted and positioned, making the combined structure of the locking bracket 32 ​​and the connecting cap 33 more compact and stable.

[0026] —Furthermore, after the horizontal axis 61 and the slot 62 are engaged and positioned, the hook at the end of the wiper arm hooks the two together to achieve a detachable connection, thus completing the wiper blade assembly structure. There are various detachable methods in the prior art. In this patent, the hook structure can be replaced by bolts, pins or buckles.

[0027] — Preferably, in order to protect the steel back plate 1, it is provided with a rubber sleeve 7. The rubber sleeve 7 has two edging grooves 71 on both sides for fixing the sides of the steel back plate 1. The rubber sleeves are provided at both ends of the pad 31, and the steel back plate 1 is covered by the edging grooves 71 on both sides to prevent rainwater from corroding the metal.

[0028] The above-described embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the implementation of this utility model. Therefore, any other modifications or equivalent substitutions to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
