Description

Weather strip test apparatus {Apparatus for testing weather strip}

The present invention relates to a weatherstrip test apparatus, and more particularly, to an apparatus for testing a weatherstrip installed on a door of a vehicle.

In general, the weather strip refers to a part made of rubber or sponge material installed on a door of a vehicle. The weather strip prevents rain, dust, etc. from entering the interior of the vehicle between the door and the vehicle body when the door is closed to the vehicle body. Alternatively, the weather strip prevents the door from vibrating when the vehicle is running, or prevents the door or the vehicle body from being impacted by colliding with the vehicle body when the door is opened or closed.

On the other hand, stick slip is a phenomenon that occurs on a contact surface between two objects, and refers to a phenomenon in which static friction and kinetic friction occur alternately. Depending on the driving condition of the vehicle or the design of the weather strip, such a stick slip phenomenon may occur at the contact surface between the weather strip and the vehicle body. That is, when the weather strip is deteriorated, a stick-slip phenomenon occurs on the contact surface between the weather strip and the vehicle body due to air introduced between the door and the vehicle body while the vehicle is running. In this case, rain or dust from the outside flows into the interior of the vehicle body Of course, wind noise is generated between the door and the vehicle body. Therefore, it can be said that it is very important to test the friction characteristics of the weather strip before mounting the weather strip on the door of the vehicle in order to prevent the occurrence of the stick slip phenomenon on the contact surface between the weather strip and the vehicle body.

The upper elevating member 1222 is a plate-shaped member and is horizontally coupled to the lower surface of the fixed body 1210. The upper elevating member 1222 is installed vertically on the lower surface of the upper elevating plate 1221. The lower elevating plate 1223 is a plate-shaped member and is disposed to be spaced apart from the upper elevating plate 1221 in parallel downward. The lower elevating member 1224 is installed vertically on the upper surface of the lower elevating plate 1223.

The elevating connection bolt 1228 penetrates from the front surface of the upper elevating member 1222 through the elevating connection groove 1227 to the upper elevating member 1222.

When the tightening amount of the elevating connection bolt 1228 is greater than a predetermined value, the elevating connection plate 1226 is in close contact with the front surface of the upper elevating member 1222, so the lower elevating member 1224 is It does not move up and down with respect to the upper elevating member 1222 and maintains a fixed arrangement. However, when the tightening amount of the elevating connection bolt 1228 is less than a predetermined value, the elevating connection plate 1226 is in a state spaced from the front side of the upper elevating member 1222 to the front side, so that the lower elevating and lowering The member 1224 is in a state capable of moving up and down with respect to the upper elevating member 1222. Accordingly, the executor may increase the height of the lower elevating member 1224 with respect to the upper elevating member 1222 by moving the elevating handle 1225 up and down while the elevating connection bolt 1228 is loosened. After adjusting, the height of the weather strip 10 is adjusted by tightening the elevating connection bolt 1228 again.

In this way, when the practitioner moves up and down while holding the elevating handle 1225, the lower elevating member 1224 moves up and down with respect to the upper elevating member 1222. And in this case, the hinge means 1230, the load cell 1240, the inclination adjustment means 1260, the holder fixing means 1270, the strip holder 1280, the holder fixing bolts 1290 move up and down, of course, The height of the weather strip 10 fixed to the strip holder 1280 is adjusted. The elevating means 1220 may be said to be for finer and more precise control of the height of the weather strip 10 as compared to the rotation shaft 1140 and the rotation handle 1150. In this way, when the height of the weather strip 10 is finely adjusted by the elevating means 1220, the strip of the weather strip 10 from the upper surface of the pressing means 1340 of the pressing unit 1300 in FIG. 3 It is possible to adjust the size of the normal force (N) applied to the protrusion (13). Therefore, the implementer can test the stick-slip characteristics of the weather strip 10 under a more diverse environment by adjusting the magnitude of the normal force (N) applied to the weather strip 10 by using the elevating means 1220. have.

The hinge means 1230 includes the strip protrusion 13 and the pressing part 1300 of the weather strip 10 when viewed along the second direction D2 (that is, when referring to FIG. 3 ). As for adjusting the angle (α) made between the upper surface of the pressing means (1340) of, the upper hinge plate (1231), the upper hinge protrusion (1232), the lower hinge plate (1233), the lower hinge protrusion (1234), the hinge It includes a pin 1235 and a rear hinge plate 1236.

4 and 5, the upper hinge plate 1231 is a plate-shaped member and is horizontally coupled to a lower surface of the lower elevation plate 1223. The upper hinge protrusion 1232 is formed to protrude downward from the lower surface of the upper hinge plate 1231. The lower hinge plate 1233 is disposed parallel to the upper hinge plate 1231 and spaced apart from the lower side of the upper hinge plate 1231. The lower hinge protrusion 1234 protrudes upward from the upper surface of the lower hinge plate 1233. In addition, the lower hinge protrusions 1234 are provided in a pair, and are respectively disposed on the left and right side surfaces of the upper hinge protrusion 1232 in the first direction D1 as a reference.

In this case, the moving body 1310 is guided along the longitudinal direction of the pair of guide rails 1170 to move along the first direction D1. That is, when the moving means 1320 presses the body block 1311 along the first direction D1, the guide block 1313 is guided along the guide rail 1170, and the moving body The 1310 moves along the first direction D1.

)이 가해진다. 따라서 상기 제어수단(1250)은, 상기 관계식 1에 기초하여 상기 마찰력(

)를 산출하게 된다.The adjusting means 1330 is seated on the upper surface of the moving body 1310. And the adjusting means 1330 is installed to be slidable along the second direction D2 with respect to the moving body 1310. The adjustment means 1330 precisely adjusts the position of the pressing means 1340 along the second direction D2 while moving along the second direction D2, and thus, on the upper surface of the pressing means 1340 It allows the weather strip 10 to be correctly seated. The pressing means 1340 is seated on the upper surface of the adjusting means 1330. And the upper surface of the pressing means 1340, the end of the weather strip 10, that is, the strip projection 13 of the weather strip 10 selectively contact. In a state in which the end of the weather strip 10 is in contact with the upper surface of the pressing means 1340, when the moving means 1320 moves the moving body 1310 along the first direction D1, weather At the end of the strip 10, the frictional force shown in FIG. 6 (

) Is applied. Therefore, the control means 1250, based on the relational equation 1, the frictional force (

) Is calculated.

On the other hand, the pressing means 1340, as a plate-shaped member, may be designed to include a plurality of bent portions. In more detail, the upper surface of the pressing means 1340 may include a first pressing surface 1341 and a second pressing surface 1342. The first pressing surface 1341 is disposed horizontally. The second pressing surface 1342 is disposed in front of the first pressing surface 1341, and when viewed along the second direction D2 (ie, based on FIG. 3), It is arranged to be inclined downward as it goes. Therefore, by allowing the end of the weather strip 10 to selectively contact the first pressing surface 1341 or the second pressing surface 1342, the practitioner tests the stick-slip characteristics of the weather strip 10 in more diverse environments. can do.
