[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] It should be understood that although terms such as upper, middle, lower, top, one end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, rather than to define any directional or sequential limitations.

[0033] As shown in Figures 1-11 , a windshield wiper includes a housing 1, a bracket 2 provided on the housing 1, and a wiper blade 3 clamped on the bracket 2. An installation groove 4 for placing the bracket 2 is formed in the housing 1. Installation convex columns 5 are formed in the installation groove 4, and installation holes 6 for placing the installation convex columns 5 are formed on the bracket 2.

[0034] During the installation process, only by inserting the bracket 2 into the installation groove 4 and making the installation convex columns 5 snap into the installation holes 6, the installation of the bracket 2 can be completed. Compared with the existing connection using rivets, it is more convenient and fast, not only improving the production efficiency but also reducing the production cost.

[0035] As shown in Figure 2 , Figure 3 , Figure 4 , as a further explanation of the implementation manner of the housing 1 in this embodiment, the housing 1 includes a middle housing 101 and end housings 102 pivotally connected to both ends of the middle housing 101. A plurality of spaced-apart limiting ribs 103 are formed on the middle housing 101, and guiding grooves 104 for placing the bracket 2 are formed on the limiting ribs 103.

[0036] During the installation of the bracket 2, when the bracket 2 is connected to the installation stud 5, the bracket 2 will be partially placed into the guiding groove 104. The limiting rib 103 can not only strengthen the structure of the entire housing 1, but also the guiding groove 104 on the limiting rib 103 can guide the bracket 2 to prevent the bracket 2 from shaking left and right, improving the stability of the bracket 2 during rotation, and also guiding the bracket 2 during the installation process, enhancing the installation convenience.

[0037] Specifically, the guiding groove 104 communicates with the installation groove 4 to form a guiding channel 105, and the rotating stud 5 is centrally arranged on the guiding channel 105. When the center of the bracket 2 is connected to the rotating stud 5, half of the bracket 2 is placed in the guiding groove 104, and the other half is placed in the guiding channel 105, greatly improving the stability of the bracket 2 and the stability of the support for the scraping strip 3.

[0038] Furthermore, a part of the installation groove 4 extends out of the middle housing 101, and a hinge post 106 is formed on the end housing 102. A hinge interface 107 for placing the hinge post 106 is formed on the installation groove 4. By placing the hinge post 106 into the hinge interface 107, the quick connection between the end housing 102 and the middle housing 101 is achieved.

[0039] Preferably, a first guiding inclined surface 108 is formed on the installation stud 5. When the bracket 2 is clamped in via the first guiding inclined surface 108, the first guiding inclined surface 108 can make it easier for the rotating stud 5 to be placed into the installation hole 6, greatly enhancing the installation convenience.

[0040] Preferably, a second guiding inclined surface 109 is formed on the hinge post 106. The second guiding inclined surface 109 can make it easier for the hinge post 106 to be placed into the hinge interface 107, further enhancing the installation convenience.

[0041] As shown in Figure 9 、 Figure 10 In some other embodiments, a connecting convex portion 301 for connecting the end housing 102 is formed on the middle housing 101. The installation groove 4 is formed on the connecting convex portion 301, and the bottom of the connecting convex portion 301 has an installation guiding arc surface 302, and an anti-shaking convex rib 303 is formed at the bottom of the connecting convex portion 301. When the middle housing 101 and the end housing 102 are connected, the hinge post 106 can slide into the hinge interface 107 along the installation guiding arc surface 302, improving the installation convenience. After the installation is completed, the anti-shaking convex rib 303 is placed inside the end housing 102 to limit the end housing 102 and prevent it from shaking excessively.

[0042] As shown in Figure 3 、 Figure 4 、 Figure 6 、 Figure 7As shown in the figure, a further explanation of the fixing implementation of the wiper strip 3 in this embodiment. Among them, the bracket 2 and the end housing 102 are formed with clamping protrusions 201 for clamping the wiper strip 3, and the wiper strip 3 is formed with a clamping groove 202 for inserting the clamping protrusion 201. The clamping protrusions 201 on the bracket 2 and the end housing 102 are inserted into the clamping groove 202 of the wiper strip 3, so that the wiper strip 3 is fixed on the housing 1.

[0043] In addition, a support groove 203 is formed below the clamping groove 202, and a support strip 204 is embedded in the support groove 203. The support strip 204 is inserted into the support groove 203 of the wiper strip 3 from both sides, improving the stability of the wiper strip 3.

[0044] Since one end of the clamping groove 202 is open and the other end is closed to form a blocking portion 205, and a blocking block 206 is arranged near the blocking portion 205. The clamping protrusion 201 is placed between the blocking portion 205 and the blocking block 206. During the installation process, the clamping protrusion 201 is inserted from the open end of the clamping groove 202 and slid until all the clamping protrusions 201 are inserted into the clamping groove 202, and the clamping protrusion 201 that is first inserted into the clamping groove 202 passes over the blocking block 206. When the clamping protrusion 201 passes over the blocking block 206 and is between the blocking portion 205 and the blocking block 206, the wiper strip 3 is fixed on the bracket 2 and the end housing 102.

[0045] Among them, one end of the blocking block 206 is arc-shaped and the other end is vertical, so that the clamping protrusion 201 can better pass over the blocking block 206 but cannot easily break away, improving the reliability of the connection of the wiper strip 3.

[0046] As Figure 3 、 Figure 5 shown, in some other embodiments, a connecting block 207 is rotatably provided on the middle housing 101. A connecting groove 208 is formed on the connecting block 207, and an abutting plate 209 is rotatably provided at the end of the connecting groove 208. An abutting protrusion 210 is formed on the abutting plate 209. During the installation of the windshield wiper, first flip the abutting plate 209 to expose the connecting groove 208, then hook the automotive windshield wiper connecting arm into the connecting groove 208, and then rotate the abutting plate 209 so that the abutting protrusion 210 on the abutting plate 209 abuts against the automotive windshield wiper connecting arm, thus realizing quick installation.

[0047] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
