BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiper blade mounted on a wiper device of an automobile to wipe a glass surface, and more particularly, by improving the coupling structure between the wiper strip and the elastic wiper frame which is in direct contact with the glass surface. A wiper blade is facilitated.

As shown in FIG. 1, a conventional wiper device includes a wiper arm 5 which rotates from side to side by a motor (not shown) built in a vehicle, and a wiper mounted on the wiper arm 5 and moving together. The blade 110 is included. The wiper blade 110 includes a wiper strip 11 for wiping the glass surface while moving in close contact with the glass surface (not shown).

The wiper blade 110 is coupled to the wiper arm 5 to rotate at a predetermined angle according to the driving of the motor. To this end, the conventional wiper blade 110 includes a plurality of main links 112 coupled to the wiper arms 5, and a plurality of wipers arms 5 coupled to the main links 112 to uniformly transfer the pressure of the wiper arms 5. The middle link 113 and a plurality of sublinks 114 coupled to the middle link 113 for connecting the wiper strip 11.

Here, the clip 115 for engaging the wiper strip 11 by being fitted in the rail groove formed in the wiper strip 11 at the ends of the middle link 113 and the sublink 114 adjacent to the wiper strip 11. ) Are formed respectively.

As such, the wiper blade 110 according to the related art has not only a complicated structure for fixing the wiper strip 11 but also a complicated assembly process, thereby increasing the effort and time required for the assembly process. There was a problem that productivity was lowered.

In addition, since each link structure moves relative to each other during operation of the conventional wiper device, there is a problem that noise occurs during operation.

In order to solve these problems, as shown in FIG. 2, the wiper strip 122 having a frame 123 having a slit 124 formed in the longitudinal direction and a rail portion 122 fitted to the slit 124 is formed. ) And a wiper blade 120 consisting of a bracket 125 for connecting the frame 123 to a wiper arm (not shown) has been developed.

In the conventional wiper blade 120 illustrated in FIG. 2, the rail portion 122 of the wiper strip 121 is inserted into the slit 124 formed in the frame 123, and the bracket is connected to the wiper arm (not shown). Since the assembly process is completed only by coupling the 125 with the frame 123, the conventional wiper blade 110 shown in FIG. 1 is assembled by connecting the plurality of links 112, 113, and 114 to each other. The assembly process is relatively simple and the parts score is reduced.

However, since the rail portion 122 is additionally formed on the wiper strip 121 made of a rubber material, a mold must be newly manufactured and a lot of materials are used to increase the cost. In addition, an excessive force is applied during the operation of inserting the rail portion 122 of the wiper strip 121 into the slit 124 formed in the frame 123 during assembly, such that the wiper strip 121 may be damaged.

The present invention is to solve these conventional problems, an object of the present invention, by combining the existing wiper strip to the elastic frame to form a wiper blade, the overall structure is simplified and the effort and time required for assembly can be reduced. At the same time, to improve the structure of the frame to utilize the existing wiper strip as it is to provide a wiper blade that does not incur additional costs in the production of the wiper strip.

According to an aspect of the present invention for achieving the above object, a wiper blade coupled to the wiper arm of the vehicle to wipe the glass surface, the wiper strip in contact with the glass surface and having a rail groove formed along the longitudinal direction; A frame having an elastic force to which the wiper strip is coupled and to closely adhere the wiper strip to the glass surface; A bracket for connecting the frame to the wiper arm; There is provided a wiper blade comprising a.

Here, the wiper blades may further include one or more spoiler members attached to the frame to prevent the wiper blades from lifting from the glass surface due to wind generated during driving of the vehicle, wherein the frame includes: A first coupling groove may be formed on an upper portion of the frame to allow the spoiler member to be coupled thereto, and a second coupling groove may be formed on the lower portion of the frame to allow the wiper strip to be coupled thereto.

Here, the frame is made of plastic, it is preferable that at least one iron core is inserted into the frame to reinforce the elastic force.

According to still another aspect of the present invention, there is provided a wiper blade coupled to a wiper arm of a vehicle to wipe a glass surface, comprising: a wiper strip contacting the glass surface and having a rail groove formed along a longitudinal direction; A frame having a coupling groove formed at a lower portion thereof to be fitted into the rail groove of the wiper strip; A bracket for connecting the frame to the wiper arm; A spoiler member coupled to an upper portion of the frame to prevent the wiper blade from being lifted from the glass surface by wind generated during driving of the vehicle; The spoiler member and the frame are provided with a wiper blade is characterized in that the adjacent coupling over the entire length of the spoiler member when coupled.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Here, according to the first embodiment of the present invention, the same wiper strip 11 as that of the conventional wiper strip 11 shown in FIG. 1 may be used as the wiper strip 11, and is shown in some enlarged view of FIG. 3 (b). As described above, the wiper strip 11 has a pair of left and right rail grooves 11a formed along the longitudinal direction.

However, in the rail groove of the conventional wiper strip 11, the wiper strip 11 made of a rubber material maintains a constant shape, and at the same time, the coupling with the plurality of links 113 and 114 can be securely performed. Although a reinforcing iron core (not shown) is inserted, according to the present invention, the frame 13 is formed of a plurality of links 112, 113, 114 (refer to FIG. 1) and a reinforcing iron core in a conventional wiper blade 110. Since all the roles can be performed, such a reinforcing iron core is no longer required in the present invention.

As shown in Fig. 4 (a), the frame 13 is made elastic so that the bonded wiper strip 11 can move while being in close contact with the glass surface of the vehicle, and at the same time, the wiper strip is viewed from the side. (11) forms an arc shape that is gently curved towards the joining point.

In addition, as shown in FIG. 4B, the frame 13 has a length equal to or longer than that of the wiper strips 11 to be joined, and is wider than the width of the wiper strips 11 to be joined. It is made of a thin metal plate having a.
