Description

Vehicle wiper support structure {The Support Device for automobile wiper}

The present invention relates to a support structure of a vehicle wiper, and more particularly, the support protrusion of the support mechanism fastened to the wiper blade is in close contact with the window to stably support the spaced wiper, and the height of the wiper blade and the frame can be adjusted. Of course, the present invention relates to a support structure for a vehicle wiper that can be used regardless of the width between the cleaning liquid discharge grill and the windshield according to the vehicle type.

As is well known, in a vehicle wiper mechanism consisting of a blade assembly and arm, pivot, ring rod, washer tank, motor, etc., the blade assembly is an important consumable to determine visibility when driving the vehicle, and if it is not properly managed, it can guarantee safe operation. Not only can it, of course, cause unpleasant noise.

In addition, while the vehicle is parked in the sun in the summer, the indoor temperature is transmitted to the blade assembly through the window, and when the snow or frost falls in the winter, the wiper blade and the window are joined to each other. And rubber wiper blades that are exposed to these weather conditions are always subject to wear, aging and deformation.

In addition, if the wiper malfunctions without spraying washer fluid in the winter when the ice is not completely frozen or the window of the vehicle is dry and dusty, the life of the wiper blade is further shortened and the life of the window is also shortened.

As such, the life of the wiper blade varies greatly depending on the use and storage conditions, so it is necessary to determine the replacement time with the appearance or wiping of the rubber rather than the mileage or time, since it is a part that is not normally used except during the rainy season. It is easy for most drivers to miss the time of replacement.

In addition, in the conventional wiper mechanism, the wiper blade and the window are always in close contact with each other as well as the driver's misuse and storage condition, which is one of the factors that seriously affect the life of the blade. The disclosed blade has the disadvantage that the deformation is inevitably intensified due to the pressure caused by continuous contact.

In addition, since the interval between the cleaning liquid discharge grille on the vehicle windshield is 5 cm to 10 cm depending on the vehicle type, the support structure can be used for all vehicle types.

The present invention has been made in view of the above-mentioned problems, and the wiper blade is formed to be curved to resemble the curved surface of the window to keep the wiper blade normally spaced from the window, and then the wiper blade is automatically operated at the moment when the wiper mechanism is operated. By forming a support structure of the vehicle wiper, which makes the vehicle adhere to the window, the gap between the ends of the wiper blade and the window is reduced, and the support protrusion is held in close contact with the window so that the wiper is stably fixed so that the wiper shakes even at high speeds. The purpose is to provide a wiper support structure to prevent the phenomenon and to use it for all the different vehicle types according to the gap between the cleaning liquid discharge grills, the vehicle type, and the type of the wiper in the windshield, which is formed differently according to the vehicle type. .

According to the invention, the holder 14, which is formed at least in the form of an open box, is fixed to a portion of the vehicle body close to the window.

2 is a perspective view showing a support structure of a vehicle wiper according to the present invention, Figure 3 is a partially exploded perspective view showing a support structure of a vehicle wiper.

In FIG. 2, the configuration of the support 101 including the lower body 110, the upper body 120, the connecting body 130, and the like is clearly understood.

The upper body 120 has a lower end portion of a cylindrical structure, and the upper and lower surfaces of the upper body and the lower portion of the form of a fastening groove 121 is formed on one side of the upper body 120, a fixed portion protruding side portion on one side of the back ( 122), and the spring engaging groove 126 and the end on the side Guide protrusions 123 protruding in a 'shape are formed.

Insert the auxiliary piece 124 to the inner surface of the fastening groove 121 and seat the frame 12 of the wiper 10, and then tighten the spoiler 125 to open the frame together with the auxiliary piece 124 (12) will be fixed.

Lower body 110 is the upper part is divided into two parts and the lower part is divided into a cylindrical shape, the end forms a support protrusion 111 to which a soft material such as rubber material is attached to the outside and protrudes on the back side To form a pressing protrusion 112 is formed.

The connecting body 130 is formed in an arc shape and has a jaw at the lower end thereof, and is interposed in a cracked upper part of the lower body 110. One end of the connecting body 130 is coupled to the upper body 120 via the pin 127 on one side.

The other end of the connecting body 130 is coupled to the lower body 110 via a spring 131. One end of the spring 131 accommodated in the lower inner space of the lower body 110 is caught by the jaw of the connecting body 130 and the other end is caught by the jaw of the lower body 110. The upper body 120 and the lower body 110 are connected to each other by the pin 127` of the other side.

The lower body 110 and the connecting body 130 coupled to the upper body 120 by the pins 127 ′ can be rotated to a predetermined range, respectively, and thus the upper body 120 and the lower body 110 are at right angles. Or maintains one of the dates.

Spoiler 125 is coupled to the upper body 120 is bent both ends, the upper surface of the wiper frame 12, the wiper 10 can be fixed to the entire stable.

The side support piece 140 forms a long hole 143 in the upper portion, forms a guide piece 141 fitted with a spring 144 on one side, and forms a movable piece 142 on the other side of the upper body 120. By being positioned on the side of the lower body 110, the protrusions on the inner surface of the pressing protrusion 112 to be caught in the long hole 143 of the side stand 140.

4A to 4B are side views showing a state before and after the operation of the vehicle wiper support structure.

While the lower body 110 and the upper body 120 are at right angles, the spring 131 exerts a force to maintain such a state. When a critical external force greater than a predetermined size is applied to the lower body 110, the spring 131 acts to maintain the state even when the lower body 110 starts to rotate and passes a predetermined critical angle.

As such, the critical angle at which the upper body 120 and the lower body 110 are converted to the right angle or the straight state is the lower end of the connecting body 130 on which the force of the spring 131 is applied to the two pins 127 on the upper body 120. Is determined based on which straight line connects (127 '), and the critical external force at this time is determined by the elastic modulus of the spring 131. That is, as the elastic modulus of the spring 131 increases, The external force to switch to the right angle or straight state is also increased.

In FIG. 4A, first, the upper body 120 of the support 101 is inserted between the frame 12 and the blade 11 to be engaged with the frame 12, and then firmly coupled with the bolts 27. An external force is applied to the lower body 110 to form a right angle with the upper body 120, and then the lower end of the lower body 110 is mounted on the holder 14. At this time, the blade 11 is spaced apart from the window by a predetermined gap, and maintains the state unless the above-described critical external force is applied. Of course, the critical external force is set smaller than the operating force of the wiper mechanism 100, so turning on the wiper mechanism while the vehicle is running rotates the frame 12 and the blade 11 assembly integrally with the support 101, and at that moment The lower body 110 is separated from the external force by the reaction of the holder 14 and forms a date (一字) with the upper body 120.

In this state, the lower body 110 and the holder 14 do not interfere while operating the wiper mechanism. When driving of the car is finished and there is no need to use the wiper mechanism, the lower body 110 is bent and mounted on the holder 14. Although this return operation may be automated, the automation is less valuable because of the economical and operational reliability problems caused by the complexity of the configuration compared to its utility.

In this case, a portion of the lower body 110 of the support 101 detachable from the holder 14 may be further provided with a rubber cover. In the present invention, a design for preventing the support 101 from randomly leaving the holder 14 due to the vibration of the vehicle is important. To this end, the dimensions of the holder 14 and the lower body 110 may be adjusted, or the friction force may be adjusted by interposing a rubber cover. In the latter case, removal of the lower body 110 is smooth, and only by replacing the cover can maintain long-term operation reliability.

Accordingly, the upper body 120 fixed to the frame 12 of the wiper is fixed in a '-' shape, and when the lower body 110 is folded forward, the push protrusion 112 rides on the top of the side support piece 140. While pushing forward, the side support piece 140 is pushed down, and the spring 131 connected to the connection body 130 inside the lower body 110 is tensioned and the connection body 130 is in the direction of the lower body 110. It will come out to have elasticity in the state that the spring 131 is folded, the upper body 120 and the lower body 110 is deformed in a right angle or date form by the connecting body (130).

On the other hand, the pressed side support 140 is the guide piece 141 is down the spring engaging groove 126 of the upper body 120 while the spring 144 is caught and compressed, the movable piece 142 of one side also goes down The fixing piece 122 formed on the body 110 serves as a forceps to lift up the blade 11.

The end of the fixing piece 122 is pushed down to enter the inside of the guide protrusion 123, the upper and lower flow is to be made safely, the folded lower body 110, the support protrusion 111 is on the surface of the window While keeping the wiper spaced apart from the window while being in close contact, the wiper is stably maintained even in the spaced state.

A rubber cover may be attached to the outer surface of the support protrusion 111 in close contact with the surface of the window to protect the glass surface of the window and to adjust the frictional force.

Subsequently, when the wiper 10 is used, when the lower body 110 is flipped oppositely, the connecting body 130 inside the lower body 110 is pushed up and the spring 131 is pushed and compressed, and the side rest 140 is disposed. The spring 144 fitted in the guide piece 141 of the guide piece 141 is to be restored while the compressed spring 144 is pushed to the original state to help the lower body 110 is restored to its original state.

Figure 5 is a perspective view showing a spoiler of the vehicle wiper support structure according to the present invention, the auxiliary piece 124 is inserted into the inner surface of the fastening groove 121 of the upper body 120 and the frame 12 of the wiper 10 After seating, the upper part is fastened to the upper surface of the wiper frame 12 by fastening the spoiler 125 to fix the frame 12 together with the auxiliary piece 124 and bending portions at both ends of the spoiler 125. (10) The whole can be fixed stably.

It is also possible to form and use only fasteners in the center portion without forming both sides of the spoiler 125.

FIG. 6 is a perspective view showing an auxiliary piece of a vehicle wiper support structure according to the present invention. As shown in the drawing, the gap between the wiper frame 112 and the blade 111 is adjusted by adjusting the thickness of the inner surface of the auxiliary piece 124. Since the wiper support mechanism 100 can be used for different wipers 10, the thickness of the inner surface of the auxiliary piece 124 is thick when the space between the frame 12 and the blade 11 is wide. If the interval between the frame 12 and the blade 11 is narrow, use the narrow thickness of the inner surface of the auxiliary piece 124 or the auxiliary piece 124 in the fastening groove 121 of the upper body 120. It is also possible to fasten the wiper frame 12 without inserting.

7A to 7B are exploded perspective views of a wiper support structure according to another embodiment of the present invention.

As another embodiment of the present invention, in the above-mentioned point, the assembly of the wiper blade 11 and the wiper frame 12 is related to the wiper mechanism which is mounted on the vehicle body via the arm 13 'so as to span the front window 200. Same as one.

1 to 4, the combination of the upper body for coupling the lower body 110 and the connecting body 130 is the same, but the upper body 120a forms a spring built-in portion 121a on one side top. Form a pin insertion hole having an uneven portion therein to fasten the uneven pin 124a and the leaf spring 125a. Form the `shape hole (123a).

`Of the upper body (120a) formed above One end of the connector 130 is connected to the `shape hole 123a by the pin 127, the other end of the connector 130 is coupled to the lower body 110 via the spring 131, the upper body ( The lower body 110 is coupled to the uneven pin 124a of the 120a, and the lower body 110 and the connecting body 130 are rotated in a predetermined range, respectively.

On the other hand, the fixing member (130a) is a plate spring is connected to the fixing plate (132a) and the `` `frame (131a) by screwing the removable piece (134a) at the end of the` `` frame (131a), the removable piece The end of the (134a) is connected to the spring (133a) fixed to one side wall of the inner frame (131a).

The fixing plate 132a of the fixing member 130a is attached to and fixed to the bonnet of the vehicle, and when the wiper is not used, the upper body 120a and the fixing member 130a are coupled to each other, and the wiper support mechanism 100a is provided. The upper body 120a may be separated from the fixing member 130a by the movement of the upper body 120a.

8A to 8B are side views showing a state before and after the operation of the vehicle wiper support structure according to another embodiment of the present invention.

When an external force is applied to the lower body 110 to form a right angle with the upper body 120a, and then the upper body 120a is mounted on the fixing member 130a, the blade 11 is spaced apart from the window by a predetermined gap.

The fixing member 130a of the present invention connects the fixing plate 132a and the `A` type frame 131a with the leaf springs of the spring inner part 135a, and the` A` type frame even when the fixing plate 132a is fixed. 131a can be opened to the outside. This is because the fixing member 130a is attached to the bonnet of the vehicle and the gap between the wipers is wide depending on the interval between the cleaning liquid discharge grills (5cm ~ 10cm) in the windshield, which is differently formed according to the vehicle type in the process of separating the wipers. In this case, the fixing protrusion 111 of the lower body 110 cannot be fixed by touching the windshield, and when the gap is narrow, the mounting protrusion 111 is also impossible to mount. 131a) to the outside or by pulling the inside to adjust the gap can be spaced apart the wiper at an appropriate interval.

Accordingly, the upper body 120a fixed to the frame 12 of the wiper is fixed in a '-' shape, and when the lower body 110 is leaned forward, the pin connected to the leaf spring is pulled up to the upper side by taking a long hole, and the lower body. As the spring 131 connected to the connection body 130 in the interior 110 is tensioned, the connection body 130 comes out in the direction of the lower body 110 to have elasticity in a state where the spring 131 is folded. The same operation can be expected without being different from FIGS. 4A-4B.

According to the above configuration and operation example, the present invention forms a wiper in a curved shape similar to the curved surface of the window to reduce the distance between the end of the wiper blade and the window, so that the support protrusion is closely supported on the window surface, the wiper spaced apart from the window To prevent the wiper from shaking during high-speed driving, and to connect the wiper frame with the height adjusting auxiliary piece that has different thicknesses of the wiper support mechanism. There is a useful effect that can be used even if the distance between the discharge grilles is different for each vehicle type.
