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 an insert-down type wiper arm nozzle installation structure.

[0006] The present application provides an insertion-down-pressure wiper arm nozzle installation structure, which adopts the following technical solution:

[0007] An insert-down type wiper arm nozzle mounting structure comprises a plug-in block and an elastic clip pre-set at both ends of a nozzle body, and a pre-positioning plate pre-set at one end of the wiper arm, wherein the pre-positioning plate is provided with a pre-positioning hole for inserting the plug-in block, and a positioning hole for buckling the elastic clip is provided at a position of the wiper arm corresponding to the elastic clip.

[0008] By adopting the above technical solution, when installing the nozzle body, the plug-in block in the nozzle body is first inserted into the pre-positioning hole at an angle, and then the nozzle body is rotated with one end of the plug-in block as a fulcrum until the elastic buckle is buckled into the positioning hole, thereby completing the installation of the nozzle body; in the above process, only precise operation is required to insert the plug-in block into the pre-positioning hole at the beginning, and the positioning can be completed by rotating the other end, which makes the overall operation convenient and greatly improves the installation efficiency.

[0009] Preferably, the pre-positioning plate extends toward the nozzle body, the pre-positioning hole is semicircular toward the wiper arm, and the plug-in block is provided with a first inclined surface on one side of the inner arc surface toward the pre-positioning hole.

[0010] By adopting the above technical solution, the pre-positioning hole is made into a semicircular shape, which is not only easy to process, but also anti-rotation, and can effectively limit the degree of freedom in all directions, so that the position of the rotating nozzle body is more accurate; in addition, by providing a first inclined surface, the plug-in block can avoid position when it is tilted and inserted into the pre-positioning hole, making the rotation of the nozzle body smoother.

[0011] Preferably, the elastic clip includes a first hook arm and a first hook end, one end of the first hook arm is elastically connected to the nozzle body, and the first hook end is arranged on one side of the other end of the first hook arm; the first hook end is buckled in the positioning hole; and a first guide slope is provided on the side of the first hook end away from the first hook arm.

[0012] By adopting the above technical solution, the nozzle body is rotated until the hook end abuts against the wiper arm, and then the nozzle body is pressed, so that the hook arm can be spontaneously moved through the action of the first guide slope, thereby improving the convenience of installation.

[0013] Preferably, the first hook end is arranged on a side of the first hook arm away from the plug-in block, and the first hook arm is inclined from the nozzle body toward a direction away from the plug-in block.

[0014] By adopting the above technical solution, the guiding inclined surface can abut against the wiper arm more accurately, thereby making it easier for the elastic buckle to be buckled in the positioning hole.

[0015] Preferably, the elastic buckle is in a "U" shape, and one end of the elastic buckle is elastically connected to the nozzle body; the wiper arm is provided with an arc plate at a position corresponding to the elastic buckle, and the locking hole extends from the arc plate to the wiper arm; before the elastic buckle is locked into the locking hole, the outer arc surface of the elastic buckle on the side away from the nozzle body abuts against the end of the arc plate away from the wiper arm.

[0016] By adopting the above technical solution, the nozzle body is rotated until the outer arc surface of the elastic clip away from the nozzle body abuts against the end of the arc plate away from the wiper arm, and then the nozzle body is pressed. After deformation into a "U" shape, the end of the elastic clip away from the nozzle body abuts against the hole wall position of the corresponding positioning hole of the arc plate, thereby achieving positioning.

[0017] Preferably, the pre-positioning plate extends toward the nozzle body, the pre-positioning hole is in a "T" shape toward the wiper arm, the shape of the plug-in block is adapted to the pre-positioning hole, and the plug-in block is provided with a second inclined surface on one side close to the wiper arm and away from the nozzle body.

[0018] By adopting the above technical solution, the pre-positioning hole is made into a "T" shape, which is not only easy to process, but also anti-rotation and can effectively limit the freedom in all directions, so that the position of the rotating nozzle body is more accurate; in addition, by providing a second inclined surface, the plug-in block can avoid position when it is tilted and inserted into the pre-positioning hole, making the rotation of the nozzle body smoother.

[0019] Preferably, the elastic clip includes a second hook arm and a second hook end, one end of the second hook arm is elastically connected to the nozzle body, the second hook end is arranged at the other end of the second hook arm and faces one side of the plug-in block; the second hook end is buckled in the positioning hole; and a second guide slope is provided on the side of the second hook end away from the second hook arm.

[0020] By adopting the above technical solution, the nozzle body is rotated until the hook end abuts against the wiper arm, and then the nozzle body is pressed, so that the hook arm can be spontaneously moved through the action of the second guide slope, thereby improving the convenience of installation.

[0021] Preferably, it further comprises a locking block preset on the wiper arm, the locking block is located between the elastic buckle and the plug-in block, and the locking block is used to be plugged into a locking groove preset on the nozzle body.

[0022] By adopting the above technical solution, when the nozzle body is rotated, the locking block is first locked into the locking groove, which limits the rotation direction of the nozzle body, so that the elastic buckle is more accurately locked into the locking hole.

[0023] Preferably, a guide surface is provided at one end of the locking block away from the wiper arm.

[0024] By adopting the above technical solution, the locking block can be inserted into the locking groove more smoothly during the process of rotating the nozzle body, thereby improving the convenience and efficiency of installation.

[0025] Preferably, it further comprises an elastic sheet preset on the nozzle body, wherein the elastic sheet is used to abut against the wiper arm.

[0026] By adopting the above technical solution, when the elastic buckle is buckled into the locking hole, the elastic sheet abuts against the wiper arm and the elastic sheet is in a pressed state, a force can be applied to the nozzle body in a direction away from the wiper arm, thereby improving the tightness of the elastic buckle abutting against the wiper arm, thereby improving the installation stability of the nozzle body and reducing the amount of shaking of the nozzle body after installation; in addition, when the elastic buckle is pushed out of the locking hole, the elastic force of the elastic sheet can be used to make the elastic buckle leave the locking hole, thereby further improving the disassembly efficiency.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When installing the nozzle body, first insert the plug-in block in the nozzle body into the pre-positioning hole at an angle, and then rotate the nozzle body with one end of the plug-in block as a fulcrum until the elastic buckle is buckled into the positioning hole, thereby completing the installation of the nozzle body; in the above process, only the insertion of the plug-in block into the pre-positioning hole at the beginning requires precise operation, and the other end can be rotated to complete the positioning, which makes the overall operation convenient and greatly improves the installation efficiency;

[0029] 2. Whether the pre-positioning hole is made into a semicircular shape or a "T" shape, it is easy to process and has the effect of preventing rotation. It can effectively limit the degree of freedom in all directions, making the position of the rotating nozzle body more accurate;

[0030] 3. Improve the tightness of the elastic buckle against the wiper arm, thereby improving the installation stability of the nozzle body and reducing the amount of shaking of the nozzle body after installation; in addition, when the elastic buckle is pushed out of the positioning hole, the elastic force of the elastic sheet can make the elastic buckle leave the positioning hole, which further improves the disassembly efficiency.
