Description

TECHNICAL FIELD

[0001] The present application relates to an electronic non-contact intelligent wiper assembly. BACKGROUND

[0002] At present, the wiper is one of the essential parts of the automobile, which is installed on the windshield of the automobile, and is used to wipe off the rain and dust on the windshield, so as to facilitate the driver to drive the automobile better. In order to realize the wiping action of the wiper, the wiper assembly is derived, which drives the wiping arm on the wiper to swing, so as to wipe the windshield.

[0003] The wiper assembly comprises a main mounting panel, a motor, a connecting rod transmission mechanism, a tubular element and other components. The tubular element is pivotally connected with a group of wiper linkage pivots at both ends. The motor is installed on the main mounting panel, and the motor is connected with the connecting rod transmission mechanism through the output shaft of the motor. The connecting rod transmission mechanism is connected with a group of wiper linkage pivots at both ends. The motor drives the connecting rod transmission mechanism through the output shaft to swing left and right. Finally, the normal wiping action of the wiper is converted through the wiper linkage pivots.

[0004] At present, the wiper assembly on the market has the following problems:

[0005] (1) When people control the wiper switch to the stop position, the wiper will not stop swinging immediately. Once the wiper swings to the initial stop position, the wiper will stop swinging. This process is mainly realized by the wiper motor. The existing wiper motor is generally connected with two main circuits, one is the wiper position switch circuit, and the other is the wiper reset switch circuit. The existing wiper reset switch circuit mainly relies on a mechanical contact type copper sheet as a circuit on-off control component. When the wiper switch is in the stop position, the wiper position switch circuit is disconnected, and the wiper reset switch circuit is turned on. At the same time, the wiper arm continues to swing. Once the wiper arm swings to the initial position, the wiper reset switch circuit is disconnected. In this process, the mechanical contact type copper sheet realizes the on-off control of the wiper reset switch circuit. Due to factors such as wear and discharge, the service life of the copper sheet will be greatly shortened, that is, the service life of the wiper motor will be shortened. If the wiper motor stops working normally, the wiper assembly cannot work normally, that is, the wiper cannot automatically reset. Therefore, it is necessary to improve the existing wiper assembly to prolong its service life.

[0006] When the wiper assembly is installed on the vehicle body, there are usually multiple mounting points, and the overall structure of the wiper assembly is a special-shaped part, so the multiple mounting points are not located on the same horizontal plane, and the spacing between the mounting points is mostly a spatial dimension, so it is difficult to ensure the installation size, and the processing requirements for the wiper assembly are very strict, which undoubtedly increases the processing difficulty of the wiper assembly, and during the processing, there will inevitably be processing errors, so it is impossible to ensure that the multiple mounting points are located on the same horizontal plane, which directly leads to the difficulty in assembling the wiper assembly with the motor vehicle, and the multiple mounting points cannot be accurately connected. SUMMARY

[0007] The technical problem to be solved by the present application is to provide an electronic non-contact intelligent wiper assembly.

[0008] To achieve the above-mentioned purpose, the present application provides the following technical scheme: an electronic non-contact intelligent wiper assembly, comprising a main mounting panel, a wiper motor and a tubular element which are respectively detachably mounted on the main mounting panel, and a first wiper arm driving shaft and a second wiper arm driving shaft which are respectively pivotally connected to the two ends of the tubular element; the output end of the wiper motor is linked with a connecting rod transmission mechanism which can simultaneously drive the first wiper arm driving shaft and the second wiper arm driving shaft to pivot; the wiper motor comprises a motor body and an end cover which is detachably connected to the motor body, and a gear is arranged in the motor body, characterized in that a magnetic element is arranged on the end face of the gear facing the end cover, and the wiper motor further comprises an integrated circuit board which is arranged between the gear and the end cover, and a Hall element which can sense the change of magnetic force is arranged on the integrated circuit board.

[0009] The above-mentioned technical scheme uses a magnetic element and a Hall element to form a non-contact switch, which replaces the existing copper sheet contact switch, and the Hall element is connected with a reset switch circuit on the integrated circuit board, thereby reducing mechanical wear and running noise and prolonging the service life of the motor.

[0010] The above-mentioned electronic non-contact intelligent wiper assembly can be further provided with the following arrangement: the magnetic element is a magnetic steel column which is detachably fixedly installed on the gear, the end face of the gear facing the end cover is provided with an installation groove which can accommodate the magnetic steel column, and the upper end of the installation groove is provided with a plurality of groups of spaced-apart hooks, and the hook bodies of each group of hooks respectively face the middle part of the installation groove.

[0011] The above-mentioned technical scheme uses a magnetic steel column which has a small volume and is easy to install, and is easy to purchase, wherein, although the present application uses steel, other metal materials with magnetism can also be used as the magnetic element in the present application; by arranging the installation groove and the hooks on the gear, when the magnetic steel column is installed, it only needs to be clamped into the installation groove through the hooks, and the hook bodies on the hooks limit the upper end of the magnetic steel column to avoid the magnetic steel column from falling off.

[0012] The electronic non-contact intelligent wiper assembly can be further provided with at least one set of first mounting points on the tubular element, at least one set of second mounting points on the main mounting panel, and mounting feet at the second mounting points, which are adjustable in position and detachably connected with the vehicle body.

[0013] The above technical solution adds mounting feet at the second mounting points, so that the specific mounting position of the second mounting points can be changed according to actual conditions until the second mounting points are connected with the fasteners of the vehicle body, thereby solving the problem of difficult assembly of the wiper with the vehicle body in the prior art, avoiding the problem of difficult assembly caused by errors, further improving the adaptability of the wiper assembly, and being applicable to multiple vehicle models. During assembly, the remaining first mounting points can be assembled with the vehicle body first, and then connected with the vehicle body through the mounting feet.

[0014] The electronic non-contact intelligent wiper assembly can be further provided with mounting feet, which are detachably connected with the main mounting panel, and provided with a position adjusting groove on the mounting foot body, and a adjusting nut detachably connected with the vehicle body above the position adjusting groove.

[0015] The above technical solution uses the mounting foot body as an intermediate part to connect the main mounting panel with the vehicle body, uses the adjusting nut to detachably connect with the fasteners of the vehicle body (the fasteners of the vehicle body include standard parts such as screws, mainly referring to the connecting parts on the vehicle body for mounting the wiper), and uses the position adjusting groove to adjust the position of the adjusting nut according to actual conditions. On the one hand, the adjusting nut is one of the position adjusting methods, and by changing the position of the adjusting nut in the position adjusting groove, the adjusting nut can be better connected with the vehicle body. On the other hand, the mounting foot body can also be rotated at an angle and cooperate with the adjusting nut to better achieve the connection between the adjusting nut and the fasteners of the vehicle body, thereby solving the problem of difficult assembly of the wiper with the vehicle body in the prior art and avoiding the problem of difficult assembly caused by errors.

[0016] The electronic non-contact intelligent wiper assembly can be further provided with transverse limiting blocks on the mounting foot body, which are distributed at the ends of the position adjusting groove and can prevent the adjusting nut from sliding out of the position adjusting groove in the sliding direction.

[0017] The above technical solution sets the transverse limiting blocks to limit the adjusting nut in the sliding direction relative to the position adjusting groove, thereby preventing the adjusting nut from coming out of the mounting foot body in the sliding direction.

[0018] The electronic non-contact intelligent windscreen wiper assembly can be further provided with a plurality of vertical limiting hooks distributed on both sides of the position adjusting groove and capable of limiting the adjusting nut in the direction perpendicular to the sliding direction.

[0019] The vertical limiting block is further arranged on the basis of the transverse limiting block, and the adjusting nut is limited in the direction of the central axis of the position adjusting groove, so that the adjusting nut is limited in the sliding direction of the adjusting nut and in the direction perpendicular to the sliding direction of the adjusting nut, and the adjusting nut will not easily fall off the mounting foot body under the action of no external force, thereby facilitating assembly and transportation.

[0020] The electronic non-contact intelligent windscreen wiper assembly can be further provided with a plurality of vertical limiting hooks distributed on both sides of the position adjusting groove and capable of limiting the adjusting nut in the direction perpendicular to the sliding direction.

[0021] The vertical limiting block is further arranged on the basis of the transverse limiting block, and the adjusting nut is limited in the direction of the central axis of the position adjusting groove, so that the adjusting nut is limited in the sliding direction of the adjusting nut and in the direction perpendicular to the sliding direction of the adjusting nut, and the adjusting nut will not easily fall off the mounting foot body under the action of no external force, thereby facilitating assembly and transportation.

[0022] The electronic non-contact intelligent windscreen wiper assembly can be further provided with a plurality of vertical limiting hooks distributed on both sides of the position adjusting groove and capable of limiting the adjusting nut in the direction perpendicular to the sliding direction.

[0023] The ball hinge and the ball cap are used as transmission connecting components between the main connecting rod and the crank, so that force transmission can be better achieved, and the torsional force, deflection force and other forces with non-unique directions that the main connecting rod and the crank bear can be reduced, thereby protecting the main connecting rod and the crank.

[0024] The electronic non-contact intelligent wiper assembly can be further provided with an error prevention gap on one side of the crank.

[0025] The error prevention gap has directivity, and is convenient to install, since the end of the crank connected with the main connecting rod needs to be riveted with a ball hinge, the error prevention gap is directed downward, so as to avoid incorrect riveting on another hole.

[0026] The electronic non-contact intelligent wiper assembly can be further provided with that the crank is riveted with the motor output end.
