Abstract
Description
Technical Field
[0001] The utility model relates to a windshield wiper component, in particular to a windshield wiper structure and a joint thereof which can firmly connect a rocker arm and a wiper rod. Background Art
[0002] Existing vehicles such as airplanes, ships, and cars usually require human operation to ensure safe movement. To ensure that the driver has a clear field of view, most of these vehicles are equipped with windshield wipers on their windows. The wipers can be mounted on a rocker arm on each vehicle via a wiper rod. The rocker arm swings back and forth to remove water or dirt attached to the vehicle's windows, allowing the driver to have a clear field of view.
[0003] However, different vehicle manufacturers produce different vehicles and their types vary, and therefore the swing arm structures and brush rods used in these vehicles also come in a variety of configurations and specifications. Generally, the swing arm and the brush rod are connected by a joint, and the joint is usually attached to the brush rod. Therefore, when the vehicle drives the swing arm to swing back and forth, the swing arm can drive the brush rod and the wiper to move back and forth on the windshield, thereby removing water or dirt adhering to the vehicle's windshield.
[0004] Due to the force of the rocker arm's reciprocating swing and the resistance of the wiper's reciprocating movement on the glass, the joint between the rocker arm and the brush rod becomes loose easily. As a result, the wiper cannot effectively wipe away the water or dirt attached to the glass and cannot provide the driver with a clear view, resulting in the need to replace the joint, brush rod and wiper. Utility Model Content
[0005] In order to solve the above problems, the purpose of the present invention is to provide a wiper structure and a joint thereof, which can be used to firmly connect the rocker arm and the brush rod, so that the connection between the brush rod and the rocker arm can be more tightly matched.
[0006] A second object of the present invention is to provide a wiper structure and a joint thereof, which can ensure that the connection between the wiper rod and the rocker arm has better strength.
[0007] The directions or similar terms described in the description of the present invention, such as "front", "rear", "upper (top)", "lower (bottom)", "inner", "outer", "side", etc., are mainly used to refer to the directions of the accompanying drawings. Each direction or similar terms are only used to assist in the description and understanding of the various embodiments of the present invention and are not intended to limit the present invention.
[0008] 4. The repairing kit for automotive dents, according to claim 1, wherein a bottom of the foot stand comprises a through-hole, and the two foot pieces comprise two bosses, wherein the bosses comprise a through-hole, a screw bolt, and a nut. The bosses comprise a through-hole, a screw bolt, and a nut. The through-holes comprise a through-hole, a screw bolt, and a nut. The through-holes comprise a through-hole, a screw bolt, and a nut.
[0009] The wiper joint of the present invention comprises a top with two downwardly extending wall panels on each side, the two wall panels each having a pivot hole, the axes of the two pivot holes being located on the same axis, the outer surfaces of the two wall panels each having at least one first protrusion, and each first protrusion protruding from the outer surfaces of the two wall panels.
[0010] Therefore, the wiper structure and its joint of the present invention can be pivotally connected to the pivotal parts of various types of brush rods through the joint, and then the joint can be combined with the rocker arm of each vehicle. Since the second distance between the inner surfaces of the two side walls of the rocker arm is slightly smaller than the first distance between the first protrusions on the two wall panels of the joint, the first protrusions of the joint and the inner surfaces of the two side walls can form a tight fit and have better strength. In this way, the brush blade on the brush rod can effectively brush away the water or dirt attached to the glass, so as to provide the driver with a clear field of vision and make the joint, brush rod and wiper have a longer service life.
[0011] The top of the joint has a first joint portion, and the top plate of the rocker arm has a second joint portion, which is combined with the first joint portion. In this way, the joint and the rocker arm can be combined to form a relatively firm effect.
[0012] The two wall plates of the joint each have a pivot hole, and the axes of the two pivot holes are located on the same axis. In this way, after the joint is combined with the brush rod, the joint can form a pivoting effect relative to the rocker arm.
[0013] The outer surfaces of the two wall panels of the joint each have at least one second protrusion, each second protrusion protruding from the outer surfaces of the two wall panels. The protrusion height of each second protrusion is less than the protrusion height of each first protrusion. In this way, the at least one second protrusion can form a rib, which has the effect of increasing the strength of the two wall panels.
[0014] Each first protrusion protrudes from the outer surface of the two wall panels by 0.1-0.5 mm, so that each first protrusion and the inner surface of the two side walls of the rocker arm can form a tight fit. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to make the above and other objects, features and advantages of the present invention more clearly understood, the following is a detailed description of preferred embodiments of the present invention with reference to the accompanying drawings.
[0045] Please refer to Figure 1 ~ Figure 3 As shown, it is a preferred embodiment of the present invention, comprising a brush rod 1, a joint 2 and a rocker arm 3. The brush rod 1 and the joint 2 can be combined, and the joint 2 can be tightly combined with the rocker arm 3.
[0046] The brush rod 1 is connected to a brush piece 11 at the bottom, and has a protruding coupling seat 12 at the top of the brush rod 1. The coupling seat 12 is preferably located in the middle of the first direction X of the longitudinal brush rod 1. Each side of the coupling seat 12 has a pivot portion 13, and the pivot portion 13 can be an axis protruding in the second direction Y. The axes of the two pivot portions 13 are located on the same axis, and the second direction Y is preferably perpendicular to the first direction X.
[0047] The joint 2 can be combined with the combination seat 12 of the brush rod 1. The joint 2 has a downwardly extending wall plate 22 on both sides of a top 21. The top 21 preferably has a first combination portion 23. The first combination portion 23 can be a protrusion or a through hole, which is not limited by the present invention. Each of the two wall panels 22 has a pivot hole 24, the axes of the two pivot holes 24 are located on the same axis, and the two pivot holes 24 are respectively used for the two pivot portions 13 of the coupling seat 12 to pivot. The outer surfaces of the two wall panels 22 also have at least one first protrusion 25, each first protrusion 25 protrudes from the outer surfaces of the two wall panels 22, and each first protrusion 25 protrudes from the outer surfaces of the two wall panels 22 by approximately 0.1~0.5㎜. Preferably, the first protrusion 25 is a plurality of strips and is arranged at intervals, and the strip-shaped first protrusions 25 are preferably parallel to the first direction X. Each of the first protrusions 25 on the two wall panels 22 has a highest point H, and the highest point H of each first protrusion 25 on one wall panel 22 and the highest point H of each first protrusion 25 on the other wall panel 22 have a first distance D1 perpendicular to the first direction X.
[0048] The outer surfaces of the two wall panels 22 of the connector 2 each further comprise at least one second protrusion 26. Each second protrusion 26 protrudes from the outer surfaces of the two wall panels 22. The protrusion height of each second protrusion 26 is less than that of each first protrusion 25, so that each second protrusion 26 can form a rib, thereby increasing the strength of the two wall panels 22. Preferably, the second protrusions 26 are multiple ribs arranged at intervals, and the second protrusions 26 are preferably parallel to the first direction X. The at least one second protrusion 26 and the at least one first protrusion 25 can be adjacent to or spaced apart from each other, or located between or outside the multiple first protrusions 25, but the present invention is not limited thereto.
[0049] The rocker arm 3 can be an existing component of various existing vehicles. One end of the rocker arm 3 has a connecting portion C, which allows the connector 2 to be connected to the connecting portion C. The connecting portion C includes a top plate 31 and two side walls 32. The top plate 31 connects the top surfaces of the two side walls 32, maintaining a predetermined distance between the two side walls 32. The top plate 31 preferably has a second engaging portion 33 that can engage with the first engaging portion 23. The second engaging portion 33 can be a through-hole or a protrusion, but the present invention is not limited thereto. The inner surfaces of the two side walls 32 are separated by a second distance D2, which is slightly smaller than the first distance D1. The bottom ends of the two side walls 32 form an unconnected opening, and each of the two side walls 32 preferably has at least one positioning member 34 at the bottom end, each positioning member 34 protruding toward the opposite side wall 32. In this way, the connector 2 can be conveniently connected to the connecting portion C.
[0050] Please refer to Figure 2 、 Figure 3 As shown, the joint 2 can be pivotally connected to the two pivotal portions 13 of the coupling seat 12 through the two pivotal holes 24 respectively, so that the joint 2 and the brush rod 1 are combined into one body, and the joint 2 is further connected to the connecting portion C of the rocker arm 3.
[0051] Please refer to Figure 3 、 Figure 4 As shown, since the second distance D2 is slightly smaller than the first distance D1, the first protrusions 25 of the connector 2 and the inner surfaces of the two side walls 32 can form a tight fit. In detail, the first protrusions 25 of the connector 2 and the inner surfaces of the two side walls 32 can form a destructive fit.
[0052] Please refer to Figure 5 , which is the case where the joint 2 is pivotally connected to the brush rod 1A of the second aspect, and then the joint 2 is connected to the connecting portion C of the rocker arm 3. The brush rod 1A of the second aspect has two pivotal portions 13 through its coupling seat 12, so that the joint 2 can be pivotally connected to the two pivotal portions 13 of the coupling seat 12 through the two pivotal holes 24, respectively, so that the joint 2 and the brush rod 1A are combined into one, and the joint 2 can also be tightly fitted to the connecting portion C of the rocker arm 3.
[0053] Please refer to Figure 6, which is the case where the joint 2 is pivotally connected to the brush rod 1B of the third aspect, and then the joint 2 is connected to the connecting portion C of the rocker arm 3. The brush rod 1B of the third aspect has two pivotal portions 13 through its coupling seat 12, so that the joint 2 can be pivotally connected to the two pivotal portions 13 of the coupling seat 12 through the two pivotal holes 24, respectively, so that the joint 2 and the brush rod 1B are combined into one, and the joint 2 can also be tightly fitted to the connecting portion C of the rocker arm 3.
[0054] To sum up, the wiper structure and its joint of the present invention can be pivotally connected to the pivotal parts of various types of brush rods through the joint, and then the joint can be combined with the rocker arm of each vehicle. Since the second distance between the inner surfaces of the two side walls of the rocker arm is slightly smaller than the first distance between the first protrusions on the two wall panels of the joint, the first protrusions of the joint and the inner surfaces of the two side walls can form a tight fit and have better strength. In this way, the brush blade on the brush rod can effectively brush away the water or dirt attached to the glass, so as to provide the driver with a clear field of vision and make the joint, brush rod and wiper have a longer service life.
