[0031] The wiper connection structure of the present invention is used to connect the wiper 1 and the wiper blade 2. The wiper connection structure includes a connection main body 30 and an upper cover 31. The connection main body 30 is installed on the wiper blade 2. A receiving cavity 300 is formed on the connection main body 30. The receiving cavity 300 is respectively open on the upper surface and the side vertical surface of the connection main body 30 to correspondingly form an upper opening 301 and an entrance 302 for the head of the wiper 1 to insert into the receiving cavity 300. The upper cover 31 is hinged to the upper opening 301, and the upper cover 31 can seal and close and open the upper opening 301. In addition, a limiting member capable of stopping and limiting the head of the wiper 1 is provided on at least one of the receiving cavity 300 and the upper cover 31 to ensure that the head of the wiper 1 does not fall off from the receiving cavity 300.

[0032] In this embodiment, preferably, one side of the upper cover 31 is hinged to one side of the upper opening 301 and integrally injection-molded, that is, the upper cover 31 and the connection main body 30 are integrally injection-molded, and the side of the upper cover 31 hinged to the upper opening 301 adopts a folding joint design. The other side of the upper cover 31 is detachably positioned and connected to the other side of the upper opening 301.

[0033] Further preferably, the other side of the upper cover 31 is snap-connected to the other side of the upper opening 301. Specifically: Please refer to Figure 2 as shown. Based on the state where the upper cover 31 seals and closes the upper opening 301, a hook 310 is integrally formed on the inner wall of the other side of the upper cover 31, and a clamping post 303 that is snap-connected and cooperated with the hook 310 is integrally formed on the other side of the upper opening 301.

[0034] In this example, preferably, there are two card hooks 310, and the card hooks 310 are preferably in an arc-shaped hook shape; correspondingly, there are two card columns 303, and the card columns 303 are preferably in a cylindrical structure. Of course, according to the design requirements, the arrangement positions of the card hooks 310 and the card columns 303 can be swapped, that is, the card hooks 310 are formed on the other side of the upper opening 301, and the card columns 303 are formed on the inner wall of the other side of the upper cover 31. Additionally, it should be noted that regarding the detachable positioning connection method between the other side of the upper cover 31 and the other side of the upper opening 301, in addition to the above-mentioned snap connection method, magnetic adsorption connection, screw locking connection, etc. can also be used, which also fall within the protection scope of this patent.

[0035] In this embodiment, preferably, limit members capable of stopping and limiting the head of the windshield wiper 1 are respectively provided on both the receiving cavity 300 and the upper cover 31.

[0036] More preferably, please refer to Figure 5 As shown, it is defined that the head of the windshield wiper 1 is inserted into the receiving cavity 300 along the front-back direction and from the entrance 302; correspondingly, one side of the upper cover 31 is hinged and integrally injection-molded with the left side of the upper opening 301, and the other side of the upper cover 31 is detachably and positionally connected to the right side of the upper opening 301;

[0037] Please refer to Figure 6 As shown, a front step portion 10 and a rear step portion 11 are formed on the head of the windshield wiper 1 and are arranged at intervals along the front-back direction; on an inner side wall (i.e., the left inner side wall of the receiving cavity 300) of the receiving cavity 300 close to the upper cover 31, a first limit step 304 that is integrally formed and matches the shape of the front step portion 10 and can stop and limit the front side of the front step portion 10, and a second limit step 305 that is integrally formed and matches the shape of the rear step portion 11 and can stop and limit the front side of the rear step portion 11 are provided; on the inner wall of the upper cover 31, a limit bump 311 that can stop and limit the rear side of the front step portion 10 when the upper cover 31 seals and closes the upper opening 301 is integrally formed. Correspondingly, an avoidance groove for avoiding and receiving the limit bump 311 is formed at a position between the front step portion 10 and the rear step portion 11 on the windshield wiper 1.

[0038] The limiting member includes the first limiting step 304, the second limiting step 305, and the limiting bump 311. However, the functions of the above three components are different. Among them, the first limiting step 304 and the second limiting step 305 are mainly to prevent the head of the wiper 1 from walking forward excessively, so that the head of the wiper 1 can move into place quickly and accurately, facilitating the upper cover 31 to be buckled. And the limiting bump 311 is mainly to prevent the wiper from falling off from the receiving cavity. In short, the above three components work together to ensure that the head of the wiper 1 does not fall off from the receiving cavity 300.

[0039] Further preferably, please refer to Figure 2 As shown, on an inner side wall (i.e., the front inner side wall of the receiving cavity 300) of the receiving cavity 300 and arranged opposite to the entrance 302, there is a warping prevention groove 306 communicated with the receiving cavity 300, and the front side of the head of the wiper 1 can be freely inserted into the warping prevention groove 306. By means of the warping prevention groove 306, the head of the wiper 1 can be prevented from warping, which is more convenient for the upper cover 31 to be buckled.

[0040] In this embodiment, preferably, a round shaft is fixedly arranged on the wiper blade 2, and a semi-circular clamping hole 307 (which can be referred to in the appendix Figure 2 As shown) is arranged on the connecting body 30. The connecting body 30 is tightly sleeved on the round shaft through the semi-circular clamping hole 307. Of course, when a large external force is applied, the connecting body 30 can rotate relative to the wiper blade 2.

[0041] In summary, compared with the prior art, the wiper connection structure of the present invention has the functions of being easy to assemble and disassemble and having a high assembly tightness, greatly improving the installation efficiency during the assembly of the wiper and the safety during use. In addition, the wiper connection structure can also play a good role in covering and protecting the joint of the wiper and the wiper blade, effectively extending the service life of the wiper.

[0042] The above is only the preferred embodiment of the present invention, but it does not limit the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
