Description

Technical Field

[0001] The invention relates to the field of automobile windshield cleaning, and in particular to a wiper arm nozzle mounting structure. Background Art

[0002] In order to facilitate the cleaning of the windshield and improve the clarity, the cars currently on the market are equipped with nozzles on the wiper arms to spray glass cleaning water on the surface of the windshield, and then the wiper arms are swung to complete the wiping of the glass surface.

[0003] Currently, the connection between the nozzle and the wiper arm is achieved by folding two U-shaped buckles on the wiper arm, and buckles are designed at the corresponding U-shaped buckles on the nozzle. During assembly, each buckle is snapped into the corresponding U-shaped buckle, thereby completing the connection between the nozzle and the wiper arm.

[0004] With regard to the above-mentioned related technologies, when connecting the nozzle and the wiper arm, it is necessary to simultaneously align and snap each buckle into the U-shaped buckle position to complete the installation, which makes the installation difficult. Summary of the invention

[0005] In order to improve installation efficiency and enhance convenience, the present application provides a wiper arm nozzle installation structure.

[0006] The present application provides a wiper arm nozzle installation structure, which adopts the following technical solution:

[0007] A wiper arm nozzle mounting structure comprises an initial positioning hook and a locking plate which are pre-arranged at the same side of the wiper arm, and an elastic buckle which is pre-arranged at one end of a nozzle body, wherein the initial positioning hook comprises: a first folding portion arranged on the wiper arm; an initial positioning groove for the first folding portion to be locked in is provided at the end of the nozzle body away from the elastic buckle, a limiting portion is provided at the groove opening of the initial positioning groove and on a side away from the locking plate, one side of the first folding portion is locked at a position between the limiting portion and the bottom of the initial positioning groove; and the elastic buckle is elastically buckled on the locking plate.

[0008] By adopting the above technical solution, when installing the nozzle body, first Figure 1 As shown, the end of the nozzle body 102 with the initial positioning groove 4 is tilted so that the first folded portion 11 is inserted into the initial positioning groove 4, and then the nozzle body 102 is rotated with one end of the initial positioning hook 1 as a fulcrum until the elastic buckle 3 is engaged with the clamping plate 2 (as shown in FIG. Figure 2As shown), the limiting portion 5 limits the first folded portion 11, thereby completing the installation of the nozzle body 102; in the above process, only precise operation is required to insert the first folded portion 11 into the initial positioning groove 4 at the beginning, and the other end can be rotated to complete the positioning, thereby making the overall operation convenient and greatly improving the installation efficiency.

[0009] Preferably, the elastic buckle comprises: a hook arm and a hook end, one end of the hook arm is elastically connected to the nozzle body, and the hook end is arranged on one side of the other end of the hook arm; the hook end is buckled on the clamping plate.

[0010] By adopting the above technical solution, the nozzle body is rotated until the hook end abuts against the locking plate, and then the hook arm is moved to make the hook end buckled on the locking plate, which is convenient to operate.

[0011] Preferably, a slope is provided on a side of the hook end away from the hook arm.

[0012] By adopting the above technical solution, when the hook end is in contact with the positioning plate, the nozzle body is pressed, and the hook arm can be moved spontaneously through the effect of the inclined surface, thereby improving convenience.

[0013] Preferably, the end surface of the elastic buckle away from the nozzle body is arc-shaped.

[0014] By adopting the above technical solution, the elastic buckle can be buckled on the clamping plate more smoothly.

[0015] Preferably, a limiting block is provided on one side of the locking plate away from one end of the wiper arm and corresponding to the elastic buckle; the initial positioning hook also includes: a second folding portion provided on the first folding portion away from one end of the wiper arm, the second folding portion is bent toward the nozzle body, and the second folding portion is used to be clamped in a limiting groove preset on the nozzle body.

[0016] By adopting the above technical solution, when the elastic buckle is arranged on the locking plate, the limit block cooperates to achieve the limitation of the elastic buckle in all directions; and when the first folding part is completely locked in the initial positioning groove, the second folding part is synchronously locked in the limit groove, thereby achieving the limitation of the initial positioning hook in all opposite directions, reducing the slight shaking that occurs during the swinging of the wiper arm, and improving the overall positioning stability.

[0017] Preferably, the ratio of the length of the limit block to the thickness of the hook arm is 1:2-1:3.

[0018] By adopting the above technical solution, the hook arm will not be separated from the limit block during the use of the wiper due to the limit block being too short, and there will be no waste of materials due to the limit block being too long.

[0019] Preferably, the elastic buckle is buckled on a side of the locking plate away from the initial positioning hook.

[0020] By adopting the above technical solution, the nozzle body is more stable as a whole after being clamped.

[0021] Preferably, the ratio of the area occupied by the limiting portion to the notch area of ​​the initial positioning groove to the notch area of ​​the initial positioning groove is 1:2-1:3.

[0022] By adopting the above technical solution, the limiting effect of the first folding portion will not be poor due to the limiting portion being too short, and the smoothness of the first folding portion being inserted into the initial positioning groove will not be reduced due to the limiting portion being too long.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Only the first folding part needs to be inserted into the initial positioning groove with precise operation at the beginning, and the other end can be rotated to complete the positioning, which makes the overall operation convenient and greatly improves the installation efficiency;

[0025] 2. When the elastic buckle is set on the clamping plate, the elastic buckle is limited in all directions in cooperation with the limiting block; and when the first folding part is completely inserted into the initial positioning groove, the second folding part is synchronously inserted into the limiting groove, thereby limiting the initial positioning hook in all reverse directions, reducing the slight shaking during the swinging of the wiper arm, and improving the overall positioning stability;

[0026] 3. Therefore, the limiting effect of the first folding portion will not be poor due to the limiting portion being too short, and the smoothness of the first folding portion being inserted into the initial positioning groove will not be reduced due to the limiting portion being too long.
