Description

Wiper blade carrier

The present invention relates to a wiper blade carrier for supporting a wiper blade assembly which contacts and wipes a windshield screen of an automobile, and in particular, the structure of the carrier can be easily assembled and separated by a structure that can be easily detached and combined. A wiper blade carrier can be arbitrarily adjusted.

Generally, a wiper system includes a wiper motor, a link configured to crank by the wiper motor, a wiper arm connected to a lower end connected to the link, and a center portion coupled to a free end of the wiper arm. And a wiper blade assembly that swings from side to side in pivot, and a wiper blade assembly coupled to the carrier in contact with the wind shield screen to wipe the wind shield screen.

The wiper blade assembly includes a support member in which a first coupling groove formed along the longitudinal direction of both ends is slidably coupled to the carrier and a second coupling groove is formed on the surface opposite to the carrier, the second coupling groove being slidably coupled to the second coupling groove. It has a rubber blade formed with cleaning ribs on the side in contact with the wind shield screen.

The wiper blade carrier includes a support arm detachably coupled to the middle portion of the wiper arm; A first link holder and a second link holder having an intermediate portion swingably coupled to both ends of the support arm, respectively, and having grippers for slidingly holding both first coupling grooves of the blade supporting member at outer ends thereof; ; A third link holder and a fourth link holder, each of which has an intermediate portion swingably coupled to each inner end of the link holders, and grippers for slidingly holding both first coupling grooves of the blade supporting member, respectively; Is done.

When the wiper blade assembly is coupled to the carrier made as described above, both ends of the first coupling grooves of the blade supporting member are slidably inserted into the gripper of the first link holder, and then the third link holder and the fourth link holder Sliding coupling the ends of both first coupling grooves in turn to the gripping rings, the gripping links of the second link holder, the blade support member can be coupled to the carrier. When the blade support member is coupled to the carrier as described above, the wiper blade assembly is inseparable because both grips of the hooks provided at one end of the support member are caught from the outside to the gripper of the second link holder. It is fixed.

When the wiper blade assembly is removed, the grippers of the hooks are pressed inwards to each other, thereby narrowing the gap between the second link holders and thus removing the wiper blade assembly.

According to the wiper system configured as described above, when the wiper motor is driven in the rain, the wiper arm is turned left and right by the crank movement of the link, and thus the carrier and the wiper blade assembly are also turned left and right to contact the windshield screen of the blade. As a result of the movement, the rainwater flowing through the windshield screen is cleaned to secure a forward view of the vehicle.

However, in the conventional wiper blade carrier as described above, the coupling structure of the first link holder and the second link holder to the support arm, and the third link holder and the fourth link to the first link holder and the second link holder, respectively. Since the coupling structure of the holders is all made of pin coupling, it is difficult to assemble them together, as well as to separate them from each other.

Therefore, when any one component constituting the carrier is damaged, it is impossible to replace the damaged component, and thus, the carrier itself must be replaced, resulting in waste of resources.

In addition, since the third link holder and the fourth link holder are coupled to the inner side of the first link holder and the second link holder, the length of the carrier is determined by the distance between the outer end of the first link holder and the outer end of the second link holder. As a result, the length of the carrier cannot be arbitrarily adjusted. Therefore, in addition to using a carrier having a different length and size according to the type and size of the vehicle, the wiper blade assembly must also use a standard having a size suitable for each carrier. Because of this, if the end portion of the wiper blade assembly is damaged, the damaged part cannot be cut and used, so the entire wiper blade assembly must be replaced.

In addition, the conventional carrier is not only to increase the weight of the vehicle, but also expensive because all components are made of metal.

The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a wiper blade carrier that can be easily coupled and detached.

Another object of the present invention is to provide a wiper blade carrier capable of arbitrarily adjusting the length.

Another object of the present invention is to provide a wiper blade carrier which can not only reuse the damaged wiper blade assembly, but also reduce the maintenance cost of the carrier.

An additional object of the present invention is to provide a wiper blade carrier which can be made of synthetic resin to reduce the weight of the vehicle and lower the manufacturing cost.

A forward vision is secured.

Other features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments based on the accompanying drawings.

Example 1

A wiper blade carrier according to Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 3.

Reference numeral 1 denotes a support arm, and a notch portion 11 is formed in the middle portion, and the notch portion 11 is rotatably provided with a connecting member 12 connected to a wiper arm (not shown). The pin grips 13 are projected downward in order at both ends of the support arm. The pin gripping ring 13 is composed of two arc-shaped protrusions facing each other at predetermined intervals in the longitudinal direction. It is preferable that the support arm 1 is made of a synthetic resin material so that the arc-shaped protrusions have a predetermined elasticity.

Reference numeral 3 is a support link holder which is coupled to both ends of the support arm 1 to detachably support the wiper blade assembly 7, and attaches and detaches and swings the pin grip 13 of the support arm 1 at the center thereof. Coupling pins 31 are formed to be coupled to each other, and blade grips 35 and 35 are formed at both ends to detachably grip and support the wiper blade assembly 7 downward.

Coupling pin 31 is preferably composed of a notch 32 formed in the center and a coupling pin 33 formed in the width direction in the center of the notch (32). Thus, the support link holders 3 can be swingably and detachably coupled to the pin grips 13 of the support arm 1 by engaging the coupling pins 33 from the bottom up. By this coupling structure, the length of the carrier may extend by twice the distance from the coupling pin portion 31 to the end of the support link holder 3.

The blade grippers 35 are each formed of two protrusions each of which is bent inward while facing each other in the width direction. Accordingly, the lower bends of the blade grip members 35 are slidably coupled to both coupling grooves 72 and 72 of the blade support member 71 supporting the blade 73, so that the blade support member 71 is connected to the carrier. It can be slidably coupled.

According to the first embodiment, the upper half of the support link holder 3 positioned below the support arm 1 in order to allow the upper surface of the support arm 1 and the upper surface of the support link holders 3 to be connected to each other without a step. It is preferable to be cut by cutting the thickness of the support arm (1).

In addition, the support link holders 3 are preferably made of a synthetic resin material.

According to the wiper blade carrier of the first embodiment configured as described above, the coupling pins 33 and 33 of both the support link holders 3 and 3 to the pin grips 13 of the support arm 1 when the carrier is assembled. The carrier can be assembled simply by inserting the parts so that the assembly and disassembly of the carrier is easy. When disassembling, insert a screwdriver or a coin between the end of the support arm 1 and the upper cutout of the corresponding support link holder 3, and flip it like a lever to support the support arm 1 and the support link holder 3 ) Can be easily separated. Therefore, if a part of the support link holders 3 or the support arm 1 is damaged, only the damaged support link holder 3 or the support arm 1 need not be replaced without replacing the entire carrier.

After assembling the carrier, the assembled carrier is coupled to the wiper arm, and the respective coupling grooves 72 and 72 of the blade support member 71 are slidably coupled to each blade gripper 35 in turn. That is, both coupling grooves 72 and 72 of the blade support member 71 are slidably coupled to the lower bends of the blade grip members 35 in order to support the blades. For example, when the blade support member 71 is slid completely from the left side to the right side, both grips 75 and 75 of the hook 74 provided at the right end of the blade support member are gripped to the right of the right support link holder 3. Gripping the 35 prevents the blade support member 71 from being pulled out to the left, so that the wiper blade assembly 7 is supported at four points by four blade grips 35.

As such, the wiper blade assembly 7 is coupled to the carrier, and then the connecting member 12 of the carrier is connected to the wiper arm. Alternatively, the carrier may be connected first to the wiper arm and then the wiper blade assembly 7 to the carrier.

When the wiper system is configured in this way and the rain shield or the front of the windshield screen is contaminated and sprayed with a cleaning solution to clean it, when the wiper motor is driven, the wiper arm is turned left and right by the crank movement of the link. By moving the blade 73 to the windshield screen by wiping the rain water or the cleaning liquid flowing through the windshield screen to secure the front view of the vehicle.

In the process of wiping the wind shield screen, since the wind shield screen has a predetermined curvature but the support link holders 3 are swingably coupled, the support link holder 3 is formed by the contact surface pressure of the blade 73 against the wind shield screen. Swinging at a predetermined angle can sufficiently adapt to the curvature.

In addition, when the blade 73 is deflected to one side using the blade 73 for a long period of time, both grips 75 and 75 of the hook 74 have the right grip 35 of the right support link holder 3. It is possible to reuse the blade assembly 7 for a long time by separating the blade assembly 7 from the carrier by releasing the gripping, and using the separated blade assembly 7 in a direction changed to the carrier.
