Description

一种新型雨刷技术领域本发明涉及一种新型雨刷 ,尤指一种用于汽车挡风玻璃的新型雨刷。背景技术雨刷一般设置于汽车的挡风玻璃前，用于在下雨天刮去落于玻璃上的雨水，以防止雨水遮住驾驶员的视线。现有技术中，雨刷的典型结构如图 1、 2所示，其设置有一长条状的胶条 1' , 在胶条 l 的两侧分另 Ή殳有纵向贯穿胶条 1' 的固定槽 11'，两侧固定槽 11' 各嵌固一弹性支撑部件 2' , 该弹性支撑部件 2' 通常为金属材质制成，其具有一定弹性及强度，用以支撑胶条 1'，且其弹性可令胶条始终贴紧于挡风玻璃上，而在弹性支撑部件 2' 的上方还设有空气导流装置 , 在雨刷的两端还组装有固定扣 4' 用以将上述三个部件固定，另外在雨刷的中央还固定有一连接装置 y , 该连接装置 5 用以连接一雨刮杆（图中未示出），从而将雨刷主体连接在雨刮杆上。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel wiper, and more particularly to a novel wiper for an automobile windshield. BACKGROUND OF THE INVENTION Wipers are generally placed in front of a windshield of a car to remove rainwater falling on the glass during rainy weather to prevent rain from obscuring the driver's line of sight. In the prior art, the typical structure of the wiper is as shown in FIG. 1 and 2, which is provided with a long strip of rubber strip 1', and a fixed slot extending longitudinally through the strip 1' is further disposed on both sides of the strip 1 11', two fixing grooves 11' are respectively embedded with an elastic supporting member 2'. The elastic supporting member 2' is usually made of a metal material, and has certain elasticity and strength for supporting the rubber strip 1', and its elasticity The strip can be always attached to the windshield, and an air guiding device is arranged above the elastic supporting member 2', and a fixing buckle 4' is further assembled at both ends of the wiper for fixing the above three components. In addition, a connecting device y is further fixed in the center of the wiper, and the connecting device 5 is connected to a wiper bar (not shown) to connect the wiper body to the wiper bar.

然而，现有的雨刷结构却存在下述缺陷： However, the existing wiper structure has the following drawbacks:

1、因为雨刷的胶条本身属于软质物体，具有极强的弹性可变形性，而弹性支撑部件 2' 为较硬的材质，其直接与胶条 1' 接触，作用力也直接作用于胶条 1' 上，这样，在刮刷使用过程中，弹性支撑部件 2' 会直接与胶条 1' 产生相互挤压，容易造成弹性支撐部件 2' 本身发生扭曲错位，从而使弹性支撑部件 1' 的压力不能均匀的施加于胶条 1' 上，直接导致雨刷刮刷时的横向稳定性降低，从而产生雨刷颤抖现象。 1. Because the rubber strip of the wiper itself is a soft object, it has strong elastic deformability, and the elastic support member 2' is a hard material, which directly contacts the strip 1', and the force acts directly on the strip. 1', in this way, during the use of the wiping brush, the elastic supporting member 2' will directly collide with the strip 1', which easily causes the elastic supporting member 2' itself to be distorted, thereby making the elastic supporting member 1' The pressure cannot be uniformly applied to the strip 1', which directly causes the lateral stability of the wiper to be reduced, thereby causing the wiper to tremble.

2、雨刷的弹性支撑部件 2 与连接装置 5' 之间的连接方式比较复杂，通常方式是通过冲床或者铆钉机等设备，采用冲压或铆钉把所述连接装置 5' 固定在弹性支撑部件 2' 上。然而，这种连接方式需要借助机器设备，因此相对制造工艺复杂、成本高、生产效率低。 2. The connection between the elastic support member 2 of the wiper and the connecting device 5' is complicated. The usual way is to fix the connecting device 5' to the elastic supporting member 2' by punching or rivet by means of a punching machine or a riveting machine. on. However, this type of connection requires the use of machinery and equipment, so the manufacturing process is complicated, costly, and production inefficient.

3、为便于安装，所述连接装置 5' 两侧设有侧壁 54' , 中间形成开放的容腔 55' , 该容腔 55' 内枢接有一连接部（图中未示出），该连接部则与所述的雨刮杆连接。现有产品中，所迷的容腔 55' 在枢接连接部之后，至少还有一侧开放，这样，雨水或灰尘就很容易从该开放处入侵到连接装置 5' 的内部，从而影响其内部部件的性能，降低使用寿命。发明内容本发明的目的在于提供一种新型雨刷，该雨刷改进其弹性支撑部件与胶条间的连接结构，以大大减少雨刷刮刷时产生的颤抖现象；且可令雨刷连接装置的安装更简单，以降低装配成本；同时还可减少灰尘或雨水进入到连接装置内部，以增加产品使用寿命。 3, in order to facilitate the installation, the connecting device 5' is provided with a side wall 54' on both sides thereof, and an open cavity 55' is formed in the middle, and a connecting portion (not shown) is pivotally connected in the cavity 55'. The connecting portion is connected to the wiper bar. In the existing product, the cavity 55' is open at least one side after the pivotal connection portion, so that rainwater or dust can easily invade from the open portion to the inside of the connecting device 5', thereby affecting the inside thereof. The performance of the components reduces the service life. SUMMARY OF THE INVENTION An object of the present invention is to provide a novel wiper which improves the connection structure between the elastic supporting member and the rubber strip to greatly reduce the chattering phenomenon caused by the wiper wiping; and can make the installation of the wiper connecting device simpler.

采用上述方案后，本发明具有下列优点： After adopting the above scheme, the present invention has the following advantages:

1、由于本发明在雨刷的胶条与弹性支撑部件之间增加了一个用以连接两者的连接板，且该连接板本身为硬质材料制成，所以硬度较高，这样弹性支撑部件连接其上后，在雨刷刮刷时能始终保持水平状态，从而提高横向刮刷的稳定性；此外，该弹性支撑部件的作用力是直接作用于硬质的连接板上，而不是软质的胶条上，从而弹性支撑部件本身不再会发生扭曲变形，雨刷胶条受力则由硬质的连接板均匀地传导过来，从而减少了不断刮刷过程中产生的颤抖。 1. Since the present invention adds a connecting plate for connecting the two between the rubber strip of the wiper and the elastic supporting member, and the connecting plate itself is made of a hard material, the hardness is relatively High, such that the elastic support member is attached thereto, and can always maintain a horizontal state when the wiper is wiped, thereby improving the stability of the lateral wiper; further, the force of the elastic support member is directly applied to the rigid connecting plate. Instead of the soft rubber strip, the elastic support member itself no longer undergoes distortion, and the wiper strip is evenly transmitted by the rigid connecting plate, thereby reducing the chattering caused by the continuous wiping process.

2、由于本发明在雨刷的连接装置底部设置了滑槽，而雨刷的弹性支撑部件或连接板则可插滑于该滑槽，然后再通过卡固结构卡合固定，该卡固结构可为限位块和定位槽，此种装配方式不需使用到冲床或铆釘机，直接以,手工方式即可实现装配，其装配工艺相对筒单，从而使装配成本降低，并可提高生产效率。 2. The present invention is provided with a sliding slot at the bottom of the connecting device of the wiper, and the elastic supporting member or the connecting plate of the wiper can be inserted and slid into the sliding slot, and then clamped and fixed by the fastening structure, the fastening structure can be The limiting block and the positioning groove can be assembled directly by manual or punching without using a punching machine or a riveting machine, and the assembly process is relatively simple, thereby reducing the assembly cost and improving the production efficiency.

3、承前段，如果令所述连接装置的滑槽设为两点滑槽，即可利用弹性支撑部件或连接板本身的弹性，使两者的卡固结构可以脱离或卡合，从而令两者可以拆卸，这样如果其中一个损坏，只需更换另一个，而不需全部丢弃，从而可防止浪费。 3. In the front section, if the chute of the connecting device is set as a two-point chute, the elasticity of the elastic supporting member or the connecting plate itself can be utilized, so that the fastening structures of the two can be disengaged or engaged, thereby making the two It can be disassembled so that if one of them is damaged, it is only necessary to replace the other one without having to discard it all, thus preventing waste.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 3, which is a first embodiment of the present invention, the wiper of the present invention mainly comprises a connected strip-shaped strip 1 and an elastic support member 2, above the elastic support member 2 An air guiding device is arranged, and fixing buckles are assembled at both ends for fixing the three components (not shown in the air guiding device and the fastening buckle), and a connecting device 5 is further fixed in the center of the wiper. . The key to the invention is that the strip 1 and the elastic support member 2 are connected by a web 7. among them:

所述胶条 1的结构与现有技术相同，其两侧分别设有纵向贯穿胶条 1的固定槽 11 , 从而在胶条 1上方形成 T字型部件 12。 The structure of the strip 1 is the same as that of the prior art, and the two sides are respectively provided with fixing grooves 11 extending longitudinally through the strip 1 to form a T-shaped member 12 above the strip 1.

所述弹性支撑部件 2的结构也与现有技术相同，其为长板状体，且具有一定弹性及强度。 The structure of the elastic supporting member 2 is also the same as that of the prior art, which is a long plate-like body and has a certain elasticity and strength.

所述连接板 7 (同时配合图 4所示 )可以塑料拉伸而成型材状结构，其长度与上述胶条 1与弹性支撑部件 2相当，而从该连接板 7的截面来看，其底部设有开口朝下的沟槽 71，其上方两侧则各设有一开口朝向侧边的凹槽 72。 The connecting plate 7 (shown at the same time as shown in FIG. 4) can be plastically stretched to form a material-like structure having a length corresponding to the above-mentioned strip 1 and the elastic supporting member 2, and from the cross section of the connecting plate 7, the bottom thereof A groove 71 with an opening facing downward is provided, and a groove 72 opening toward the side is provided on each of the upper sides.

再同时配合图 5所示，在安装时，先将所述胶条 1以其 T.字型部件 12对准所述连接板 7底部的沟槽 71 , 使两者卡合在一起，再向内拉滑胶条 1 , 从而使该 T字型部件 12被牢固地嵌入固定在所述沟槽 71内，由于该连接板 7为硬质塑料制成，因此其沟槽 71具有较高的硬度，能够牢固地夹紧该胶条 1; 然后，再将两弹性支撑部件 2从两侧插于所述连接板 7上方两侧的凹槽 72内，由于弹性支撑杆 2的厚度和所述凹槽 72的相吻合，所以令弹性支撑部件 2被牢固固定于该凹槽 72内，由于该连接板 7具有较高硬度，且所述弹性支撑部件 2 在雨刷横向刮刷过程中，直接只与该连接板 7接触，并且，弹性支撑部件 2同时被连接板 7的凹槽 72上下夹紧，这样，从整体上避免了弹性支撑部件 2错位的可能，提高了其横向刚度，增加了稳定性。 At the same time, as shown in FIG. 5, at the time of installation, the strip 1 is first aligned with the groove 71 at the bottom of the connecting plate 7 with its T.-shaped member 12, so that the two are stuck together. The inner slide rubber strip 1 is such that the T-shaped member 12 is firmly embedded and fixed in the groove 71. Since the connecting plate 7 is made of hard plastic, the groove 71 has a high hardness. The rubber strip 1 can be firmly clamped; then, the two elastic support members 2 are inserted from both sides into the grooves 72 on both sides above the connecting plate 7, due to the thickness of the elastic support rod 2 and the concave The groove 72 is matched, so that the elastic supporting member 2 is firmly fixed in the groove 72, since the connecting plate 7 has a high hardness, and the elastic supporting member 2 is directly used only during the lateral wiping process of the wiper. The connecting plate 7 is in contact, and the elastic supporting member 2 is simultaneously clamped up and down by the groove 72 of the connecting plate 7, so that the possibility of dislocation of the elastic supporting member 2 is avoided as a whole, the lateral rigidity is improved, and the stability is increased. .

如图 6、 7所示，本发明所述连接装置 5的底部设有滑槽 51 , 该滑槽 51可以为近似贯穿连接装置的长槽，也可如图中所示，在该连接装置 5底部的前后各设有一对相对的槽口 52，每对相对的槽口 52 与连接装置 5的内腔壁形成一个滑槽 51; 另在该连接装置 5的底部内壁设有限位块 53。 As shown in FIG. 6 and FIG. 7, the bottom of the connecting device 5 of the present invention is provided with a sliding slot 51, which may be a long slot extending through the connecting device, or as shown in the figure, in the connecting device 5 A pair of opposite slots 52 are defined in the front and rear of the bottom portion, and each pair of opposite slots 52 forms a sliding slot 51 with the inner cavity wall of the connecting device 5; and a limiting block 53 is disposed on the bottom inner wall of the connecting device 5.

所述弹性支撑部件 2的中部外侧设有定位槽 21。 A positioning groove 21 is provided on the outer side of the central portion of the elastic supporting member 2.

在装配时，将上述通过连接板 7組装好的胶条 1及弹性支撑部件 2, 以弹性支撑部件 2从端部直接插入到所述连接装置 5的底部滑槽 51 内，当该连接装置 5滑到两弹性支撑部件 2的中部时，其内的限位块 53直接会卡入到弹性支撑部件 2外侧的定位槽 21内，从而最终定位，把该连接装置 5紧密固定连接在弹性支撑部件 2上。该固定方式能保证所述连接装置 5与弹性支撑部件 2不脱离，连接牢固。 At the time of assembly, the above-mentioned rubber strip 1 and elastic support member 2 assembled through the connecting plate 7 are inserted into the bottom sliding groove 51 of the connecting device 5 from the end portion with the elastic supporting member 2 as the connecting device. When sliding to the middle of the two elastic supporting members 2, the limiting block 53 therein directly engages into the positioning groove 21 outside the elastic supporting member 2, thereby finally positioning, and the connecting device 5 is tightly fixedly connected to the elastic support. On component 2. The fixed side The type can ensure that the connecting device 5 and the elastic supporting member 2 are not separated, and the connection is firm.

需要说明的是，所述槽口 52固定点必须横向地紧密固定该弹性支撑部件 2, 这是为了避免横向刮刷时，由于没有紧密固定，导致缝隙过大，而引起雨刷的抖动；同时，所述槽口 52固定点在纵向上必须与该弹性支撑部件 2有一定距离的空隙 ,该空隙是为了保证该弹性支撑部件 2在自然状态下保持原有的曲率和应力。 It should be noted that the fixing point of the notch 52 must be tightly fixed to the elastic supporting member 2 in the lateral direction. This is to prevent the gap from being too large and causing the shaking of the wiper when the lateral wiping is not performed. The notch 52 is fixed at a certain distance from the elastic supporting member 2 in the longitudinal direction, and the gap is to ensure that the elastic supporting member 2 maintains the original curvature and stress in a natural state.

再者，当本发明所述的连接装置 5的滑槽 51如图中所示为由槽口 52构成的两点滑槽时，所述的连接装置 5即可方便与弹性支撑部件 2脱离。具体拆卸方式为：由于所述弹性支撑部件 2为金属杆状体，因此其具有一定的弹性，这样在拆卸时先该弹性支撑部件 2掰直，而拉直后的弹性支撑部件 2中部的定位槽 21即会从连接装置 5的限位块 53上脱离，此时只需向一侧拉出弹性支撑部件 2, 从而可令连接装置 5与弹性支撑部件 2分离，达到可拆卸的目的。 Further, when the chute 51 of the connecting device 5 of the present invention is a two-point chute formed by the notch 52 as shown in the drawing, the connecting device 5 can be easily separated from the elastic supporting member 2. The specific disassembly manner is as follows: since the elastic support member 2 is a metal rod-shaped body, it has a certain elasticity, so that the elastic support member 2 is straightened when disassembled, and the middle portion of the elastic support member 2 after straightening is positioned. The groove 21 is detached from the stopper 53 of the connecting device 5, and at this time, the elastic supporting member 2 only needs to be pulled out to one side, so that the connecting device 5 can be separated from the elastic supporting member 2 for detachable purposes.

此外，上述连接装置 5与弹性支撑部件 2的限位块 53与定位槽 21 , 也可由其它卡固结构代替。 In addition, the connecting device 5 and the limiting block 53 and the positioning groove 21 of the elastic supporting member 2 may be replaced by other fastening structures.

再如图 8、 9所示，所述的连接装置 5两侧设有侧壁 54, 该两侧壁 54内则形成开放的容腔 55，该容腔 55内枢接有一连接部 8, 该连接部 8用以与一雨刮杆（图中未示出）连接。 As shown in FIG. 8 and FIG. 9 , the connecting device 5 is provided with a side wall 54 , and an open cavity 55 is formed in the two side walls 54 . The connecting portion 8 is pivotally connected to the cavity 55 . The connecting portion 8 is for connecting with a wiper bar (not shown).

另外，该连接装置 5的容腔 55开放处还设有一面盖 9，该面盖 9 的一侧枢接于该连接装置 5的其中一侧壁 54上，其另一侧则卡固于连接装置 5的另一侧壁 54上。而该卡固方式是在相应的侧壁 54内侧设有一"" ^粒 56, 而在面盖 9的相对位置设有一凹槽 91。 In addition, a cover 9 is further disposed at the opening of the cavity 55 of the connecting device 5. One side of the cover 9 is pivotally connected to one side wall 54 of the connecting device 5, and the other side is fastened to the connection. On the other side wall 54 of the device 5. The fastening means is provided with a "" grain 56 inside the corresponding side wall 54 and a recess 91 at the opposite position of the face cover 9.

所述的面盖 9的设置，可将连接装置 5容腔 55的开放处予以封闭，从而可减少灰尘及雨水的入侵，进而增加产品的使用寿命。 The cover 9 is arranged to close the opening of the cavity 55 of the connecting device 5, thereby reducing the intrusion of dust and rain, thereby increasing the service life of the product.

再如图 10所示，当所述的面盖 9一侧枢接于连接装置 5的一侧后，其可沿着枢接轴向一侧翻开，从而将面盖 9打开，这样可便于安装。而该面盖 9另一侧与连接装置 5侧壁的卡固结构也可采用过盈配合的方式。 As shown in FIG. 10, when the side of the cover 9 is pivotally connected to one side of the connecting device 5, it can be opened along one side of the pivoting axis, thereby opening the cover 9, which is convenient. installation. The fastening structure of the other side of the cover 9 and the side wall of the connecting device 5 can also be used in an interference fit manner.

本发明通过上述结构及组装方式组装了胶条 1、弹性支撑部件 2、连接板 7及连接装置 5后，与现有技术相同，可再另外安装空气导流装置 3及两端的固定扣 4等，其安装方式及结构与现有产品类似，不赘述。 After the rubber strip 1, the elastic support member 2, the connecting plate 7 and the connecting device 5 are assembled by the above structure and assembly method, the air guiding device 3 and the fixing buckles 4 at both ends can be additionally installed as in the prior art. The installation method and structure are similar to the existing products, and will not be described.

本发明第二实施例与第一实施例的不同之处在于：所述的连接板 7A的结构不同。具体描述如下： The second embodiment of the present invention is different from the first embodiment in that the structure of the connecting plate 7A is different. The specific description is as follows:

所述连接板 7A (同时配合图 11所示）同样可以塑胶拉伸而成型材状结构，其长度与上述胶条 1与弹性支撑部件 2相当，而从该连接板 7A的截面来看，其底部设有开口朝下的 C形槽 73A, 其顶部则设有连接槽 74A，该连接槽 74A可为开口朝上的 C形槽。所述胶条 1的结构同样与现有技术相同，其两侧分别设有纵向贯穿胶条 1的固定槽 11 , 从而在胶条 1上方形成 T字型部件 12。 The connecting plate 7A (shown at the same time as shown in FIG. 11) can also be plastically stretched to form a material-like structure having a length corresponding to the above-mentioned strip 1 and the elastic supporting member 2, and from the cross section of the connecting plate 7A, The bottom is provided with a C-shaped groove 73A with an opening facing downward, and the top portion is provided with a connecting groove 74A, which may be a C-shaped groove with an opening facing upward. The structure of the strip 1 is also the same as in the prior art, and the two sides are respectively provided with fixing grooves 11 extending through the strip 1 in the longitudinal direction, so that the T-shaped member 12 is formed above the strip 1.

所述弹性支撑部件 2A仅设置一条，其为长板状体，且具有一定弹性及强度。 The elastic supporting member 2A is provided only in one piece, which is a long plate-like body and has a certain elasticity and strength.

如图 12所示，组装时，先将弹性支撑部件 2A插于所述连接板 7A顶中的连接槽 74A内，并使两者平齐；然后，将所述胶条 1一端以其 T字型部件 12对准所述连接板 7A底部的底部 C形槽 73A，使两者卡合在一起，再向内拉滑胶条 1 , 从而使该 T字型部件 12被牢固地嵌入固定在所述 C形槽 73A内，直到该胶条 1也与连接板 7A平齐。此种结构方式，所述胶条及弹性支撑部件与连接板的连接，只需筒单的插接，且两侧的弹性支撑部件合并而为一个弹性支撑部件，这种组装方式不再需要以焊接或铆接的方式将两侧的弹性支撑部件连接在一起，因此可減少加工工序，且这种组装方式非常容易，从而可降低力 p工成本。 As shown in FIG. 12, when assembling, the elastic supporting member 2A is first inserted into the connecting groove 74A in the top of the connecting plate 7A, and the two are flush; then, the strip 1 is end-shaped with its T shape. The type member 12 is aligned with the bottom C-shaped groove 73A at the bottom of the connecting plate 7A, so that the two are engaged together, and then the slide strip 1 is pulled inwardly so that the T-shaped member 12 is firmly embedded and fixed therein. The inside of the C-shaped groove 73A is until the strip 1 is also flush with the connecting plate 7A. In this configuration, the connection between the strip and the elastic supporting member and the connecting plate is only required to be inserted into the single tube, and the elastic supporting members on both sides are combined to form an elastic supporting member. This assembly method is no longer required. The method of welding or riveting connects the elastic support members on both sides together, thereby reducing the number of processing steps, and the assembly method is very easy, thereby reducing the cost of labor.

上述结构的连接方式，由于所述的弹性支撑部件 2A被包覆于所述连接板 7A的连接槽 74A内，而不再外露，因此其与所述连接装置的组装结构也与上述第一实施例有所不同，具体结构如图 13及图 14 所示。本实施例所述的连接装置 5与第一实施例相同，其同样设有滑槽 51、槽口 52及限位块 53等结构。而本实施例不同的是：所述连接板 7A的中部外侧设有定位 ^ 75A。 Since the elastic support member 2A is covered in the connecting groove 74A of the connecting plate 7A and is not exposed, the assembled structure of the connecting device and the first embodiment are also the first embodiment. The examples are different. The specific structure is shown in Figure 13 and Figure 14. The connecting device 5 of the present embodiment is the same as the first embodiment, and is also provided with a structure such as a sliding groove 51, a notch 52, and a limiting block 53. The difference between this embodiment is that: the outer side of the connecting plate 7A is provided with a positioning ^ 75A.

在装配时，将上述通过连接板 7组装好的胶条 1及弹性支撑部件 2A,以连接板 7A顶部的连接槽 74A两外端直接插入到所述连接装置 5的底部滑槽 51内，当该连接装置 5滑到连接板 7A的中部时，其内的限位块 53直接会卡入到连接板 7A外侧的定位槽 75 A内，从而最终定位，把该连接装置 5紧密固定连接在连接板 7A上。之后即可以卡扣方式组装空气导流装置 3及两端的固定扣 4。 During assembly, the rubber strip 1 and the elastic supporting member 2A assembled through the connecting plate 7 are directly inserted into the bottom sliding groove 51 of the connecting device 5 at the outer ends of the connecting groove 74A at the top of the connecting plate 7A. When the connecting device 5 slides to the middle of the connecting plate 7A, the limiting block 53 therein directly engages into the positioning slot 75 A outside the connecting plate 7A, thereby finally positioning, and the connecting device 5 is tightly fixedly connected to the connecting device 5 On board 7A. The air deflector 3 and the retaining clips 4 at both ends can then be assembled in a snap-fit manner.

当然，所述的连接板结构并不局限于上述两种，其也可如图 15 所示，该连接板 7B的底部同样设有开口朝下的 C形槽 73B，其顶部也设有连接槽 74B, 所不同的是：所述连接槽 74B为一封闭形槽，该封闭槽同样可用以连接固定所述的弹性支撑部件 2A, 从而可达到预期的效果。 Of course, the structure of the connecting plate is not limited to the above two types. As shown in FIG. 15, the bottom of the connecting plate 7B is also provided with a C-shaped groove 73B with an opening facing downward, and a connecting groove is also provided at the top of the connecting plate 7B. 74B, the difference is that: the connecting groove 74B is a closed-shaped groove, and the closing groove can also be used to connect and fix the elastic supporting member 2A, thereby achieving the desired effect.
