Description

Technical Field

[0001] The invention relates to the field of automobile windshield cleaning, in particular to an insertion-down-pressing wiper arm nozzle installation 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, the present application provides a rotating wiper arm nozzle installation structure.

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

[0007] A rotary wiper arm nozzle mounting structure comprises a first clamping piece for clamping one end of a nozzle body to the wiper arm, a second clamping piece for clamping the other end of the nozzle body to the wiper arm, and a rotating shaft pre-arranged between the two ends of the nozzle body, wherein the rotating shaft is used to be inserted into a rotating hole preset on the wiper arm; the clamping direction of the first clamping piece and the second clamping piece is in the rotation direction of the rotating shaft.

[0008] By adopting the above technical solution, when installing the nozzle body, first insert the rotating shaft into the rotating hole, and then rotate the nozzle body until the two ends of the nozzle body are connected to the wiper arm through the first clamping piece and the second clamping piece; in the above process, only precise operation is required at the beginning to insert the rotating shaft into the plug-in hole, and then only the nozzle body needs to be rotated to complete the positioning, which makes the overall operation convenient and greatly improves the installation efficiency.

[0009] Preferably, the first clamping member comprises: a hook for being pre-elastically connected to one end of the nozzle body, and a clamping groove for the hook to buckle into is provided at the end of the wiper arm.

[0010] By adopting the above technical solution, the nozzle body is rotated until the hook abuts against the outer wall of the wiper arm, and then the hook is moved and the nozzle body is continued to be rotated, so that the hook can be buckled into the slot; the structure is simple and practical.

[0011] Preferably, an arcuate surface is provided on the outer side wall of the wiper arm at a position corresponding to the slot; when the nozzle body is rotated until the hook is buckled into the slot, the hook arm of the hook abuts against the arcuate surface.

[0012] By adopting the above technical solution, when the nozzle body is rotated until the hook abuts against the outer wall of the wiper arm, continuing to rotate the nozzle body can cause the hook to spontaneously deform through the guiding effect of the arc surface, so that the hook is buckled into the slot, thereby making the overall operation more convenient.

[0013] Preferably, the second clamping member comprises: a clamping block for pre-connecting to the nozzle body and a curved plate for pre-connecting to the wiper arm, the curved plate opening faces the first clamping member, and the clamping block is clamped in the curved plate.

[0014] By adopting the above technical solution, the nozzle body is rotated until the clamping block is clamped in the arc plate, so that one end of the nozzle body is clamped on the wiper arm. The structure is simple and the operation is convenient.

[0015] Preferably, elastic strips are provided on both sides of the block, and the elastic strips abut against the inner arc surface of the arc plate.

[0016] By adopting the above technical solution, when the clamping block is clamped into the arc plate, the elastic strip is squeezed to improve the stability of the clamping block being clamped into the arc plate.

[0017] Preferably, an abutment block is provided on one side of the clamping block, and the abutment block abuts against the side wall of the arc-shaped plate.

[0018] By adopting the above technical solution, when the nozzle body is rotated until the clamping block is completely inserted into the arc plate, the abutment plate abuts against the side wall of the arc plate, limiting the position of the nozzle body and improving installation accuracy.

[0019] Preferably, a limit block is circumferentially arranged on an outer side wall of one end of the rotating shaft close to the nozzle body, and the limit block abuts against a side of the wiper arm close to the nozzle body.

[0020] By adopting the above technical solution, when the rotating shaft is inserted into the rotating hole, the limit block abuts against the wiper arm, thereby reducing the shaking that occurs when the nozzle body is rotated.

[0021] Preferably, a guide surface is extended circumferentially at one end of the rotating shaft away from the nozzle body.

[0022] By adopting the above technical solution, the rotating shaft can be inserted into the rotating hole more smoothly.

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

[0024] 1. You only need to insert the rotating shaft into the socket hole accurately at the beginning, and then you only need to rotate the nozzle body to complete the positioning, which makes the overall operation convenient and greatly improves the installation efficiency;

[0025] 2. When the nozzle body is rotated until the hook abuts against the outer wall of the wiper arm, the nozzle body can be rotated further to guide the arc surface so that the hook is deformed spontaneously and buckled into the slot, thereby making the overall operation more convenient;

[0026] 3. When the rotating shaft is inserted into the rotating hole, the limit block abuts against the wiper arm to reduce the shaking that occurs when the nozzle body is rotated. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The cross-section of the wiper arm 101 is U-shaped, and the opening of the wiper arm 101 is arranged horizontally; the nozzle is installed directly above the wiper arm 101, that is, the nozzle is installed on one of the wing plates 104 of the wiper arm 101, and the nozzle includes a nozzle body 102 and an outer shell 103, and the nozzle body 102 and the outer shell 103 are integrally formed, and the nozzle body 102 is installed on the wing plate 104 of the wiper arm 101. When the nozzle is installed on the wiper arm 101, the outer shell 103 faces outward, so as to shield the connection structure between the nozzle body 102 and the wiper arm 101.

[0035] The present application discloses a rotary wiper arm nozzle mounting structure. Figure 1 and Figure 2 The mounting structure includes a first clamping member 1, a second clamping member 2 and a rotating shaft 3. The first clamping member 1 is used to clamp one end of the nozzle body 102 to one end of the wing plate 104 of the wiper arm 101, and the second clamping member 2 is used to clamp the other end of the nozzle body 102 to the other end of the wing plate 104 of the wiper arm 101; the rotating shaft 3 is integrally formed and arranged on the side of the nozzle body 102 close to the wiper arm 101 and is located between the first clamping member 1 and the second clamping member 2. The wing plate 104 of the wiper arm 101 is provided with a rotating hole 4, and the rotating shaft 3 is plugged into the wing plate 104 of the wiper arm 101 through the rotating hole 4; the clamping direction of the first clamping member 1 and the second clamping member 2 is in the rotation direction of the rotating shaft 3; so that when the rotating shaft 3 is inserted into the plug-in hole, the nozzle body 102 can be rotated to connect the nozzle body 102 and the wiper arm 101 through the first clamping member 1 and the second clamping member 2.

[0036] Reference Figure 2 and Figure 3 The first clamping component 1 includes a hook 11, which is "L"-shaped. The hook 11 includes a hook arm 111 and a hook end 112. One end of the hook arm 111 is elastically connected to one end of the nozzle body 102, and the hook end 112 is integrally formed at the other end of the hook arm 111; a slot 6 is provided on the wing plate 104 of the wiper arm 101 corresponding to one end of the hook 11, and the hook arm 111 is clamped to the wing plate 104 of the wiper arm 101 through the slot 6, and the hook end 112 abuts against the side of the wing plate 104 of the wiper arm 101 away from the nozzle body 102, so that the wing plate 104 of the wiper arm 101 is clamped in the hook 11, completing the connection between one end of the nozzle body 102 and one end of the wing plate 104 of the wiper arm 101.

[0037] Reference Figure 4 The wiper arm 101 has an arc surface 5 on its horizontal outer side wall facing outwards and at a position corresponding to the slot 6. When the nozzle body 102 is rotated until the hook 11 is buckled into the slot 6, the hook arm 111 abuts against the arc surface 5. Thus, the hook 11 can be buckled into the slot 6 by simply rotating the nozzle body 102.

[0038] Reference Figure 2 and Figure 3 The second clamping member 2 includes a clamping block 21 and an arc plate 22. The clamping block 21 is integrally connected to the end of the nozzle body 102 away from the hook 11. The corners of the outer wall of the clamping block 21 are all chamfered; the arc plate 22 is arranged at the end of the wing plate 104 of the wiper arm 101 away from the card slot 6. The arc plate 22 is "U"-shaped. One end of the arc plate 22 is integrally connected to the wing plate 104 of the wiper arm 101. The arc plate 22 is connected from the wiper arm 101 to the wiper arm 101. The wing plate 104 is bent toward the nozzle body 102, and the opening of the arc plate 22 faces the hook 11; the block 21 is clamped in the arc plate 22; elastic strips 23 are provided on both sides of the block 21, and the elastic strips 23 abut against the inner arc surface of the arc plate 22; when the nozzle body 102 is rotated with the rotating shaft 3 as the rotating axis, the block 21 can be smoothly clamped into the arc plate 22, and the elastic strips 23 can stabilize the block 21 in the arc plate 22.

[0039] An abutment block 24 is integrally formed on one side of the clamping block 21 in the rotation direction. When the clamping block 21 is clamped into the arc-shaped plate 22 , the abutment block 24 abuts against the side wall of the arc-shaped plate 22 to achieve a limiting effect.

[0040] Reference Figure 2 and Figure 3 , limit blocks 31 are arranged at equal intervals along the circumferential direction on the outer wall of one end of the rotating shaft 3 close to the nozzle body 102, and the limit blocks 31 abut against the side of the wing plate 104 of the wiper arm 101 close to the nozzle body 102; therefore, when the rotating shaft 3 is inserted into the rotating hole 4, the limit block 31 abuts against the wing plate 104 of the wiper arm 101, so that the subsequent rotation of the nozzle body 102 is more stable.

[0041] A guide surface 32 is provided at one end of the rotating shaft 3 away from the nozzle body 102 and extending in the circumferential direction, so that the rotating shaft 3 can be inserted into the rotating hole 4 more smoothly.

[0042] The implementation principle of a rotating wiper arm nozzle mounting structure of an embodiment of the present application is: when installing the nozzle body 102, first insert the rotating shaft 3 into the rotating hole 4, and then rotate the nozzle body 102 until the hook 11 is buckled into the slot 6 and the block 21 is snapped into the arc plate 22, thereby completing the connection between the two ends of the nozzle body 102 and the wiper arm 101.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
