Description

Technical Field

[0001] The present invention relates to the field of sliding resistance simulation test devices, and particularly to a sliding resistance simulation test device for a window glass guide groove sealing strip. Background Art

[0002] Sliding resistance is an important parameter of a window glass guide groove sealing strip, which directly affects the lifting speed of the window glass and the wear speed of the glass guide groove sealing strip. A sealing strip with a large sliding resistance is more likely to wear during a wear experiment or actual use, which is not conducive to the lifting of the window glass.

[0003] Chinese Patent CN203848965U discloses a sliding resistance test device for a window glass guide groove sealing strip, which includes a horizontal workbench, a loading unit, a sliding unit, and a power unit. The loading unit includes a horizontal adjustment component and a vertical adjustment component for adjusting the position of the sealing strip to make it close to the glass sample. Compared with the resistance test directly carried out on the car door, this sliding resistance test device for a window glass guide groove sealing strip has high test efficiency and reduces costs, but its structure and operation process are too complex. Chinese Patent CN208155497U discloses a sliding resistance simulation test device for a window glass guide groove sealing strip. By setting a U-shaped test rail for placing the sealing strip, a clamping component, a power component for driving the glass sample to move along the length direction of the U-shaped test rail, and a sensing component arranged between the glass sample and the power component, the clamping component includes a slide rail arranged parallel to the U-shaped test rail, a base slidably arranged on the slide rail, and a clamping arm for clamping the glass sample. Through the above structural settings, the structure of the test device is simplified and the operation is made more simple. However, since the glass generates friction with the inner and outer lips in the guide groove sealing strip, the relative position between the glass and the inner and outer lips directly affects the resistance test result. To obtain a more accurate resistance test result, it is necessary to change the position of the glass and measure multiple sets of data. In the above patents, the position of the glass is fixed at the beginning of the measurement, and the position of the glass cannot be adjusted during the measurement. After a measurement is completed, the position of the glass needs to be adjusted manually, and this process needs to be repeated many times to obtain the required data, which is complex in operation and affects the test efficiency. Summary of the Invention

[0004] The purpose of the present application is to provide a simulation test device for the sliding resistance of the window glass guide groove sealing strip. By slidably installing a side shift plate on a clamping frame, a reciprocating lead screw is also rotatably installed on the clamping frame.

One end of the reciprocating lead screw is installed with a one-way driving component, and a toothed plate is installed at one end inside the steam box.

The glass is fixed below the clamping seat through a clamping component. The clamping seat is fixedly connected to the side shift plate. When the pushing mechanism drives the glass to move back and forth along the test track, it drives the clamping frame to move back and forth along the air cushion slide rail.

[0015] 1. In the present invention, a side shift plate is slidably mounted on a clamping frame, and a reciprocating lead screw is rotatably mounted on the clamping frame. The reciprocating lead screw is in threaded cooperation with the side shift plate. One end of the reciprocating lead screw is equipped with a one-way drive assembly, and a toothed plate is mounted at one end inside the steam box.

The glass is fixed below the clamping seat through a clamping assembly, and the clamping seat is fixedly connected to the side shift plate. When the pushing mechanism drives the glass to move back and forth along the test track, the clamping frame is driven to move back and forth along the air cushion slide rail.

In the present invention, by providing a steam box, both the glass clamping mechanism and the test track are arranged inside the steam box, so that the glass and the sealing strip are both installed inside the steam box. Introducing steam into the steam box can change the temperature during the sliding resistance test. After the side shift plate completes the movement of the maximum one-way distance, the glass also completes the movement of the maximum one-way distance, and the sliding resistance data required at the same temperature is tested. At this time, the temperature inside the steam box is changed, and the pushing mechanism is started again. Next, the side shift plate and the glass both move back until the side shift plate and the glass return to the initial position, and the sliding resistance data required at this temperature is tested. The sliding resistance data at different temperatures can be measured without manual adjustment of the glass position, further improving the measurement efficiency.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: Refer to Figures 1 - 5 The sliding resistance simulation test device for a window glass guide groove sealing strip shown in the figure, which includes a steam box 2, a glass clamping mechanism 3, a test rail 4 and a pushing mechanism 5. The glass clamping mechanism 3 is installed inside the steam box 2. A fixed plate 201 is fixedly installed on the inner wall of the steam box 2, and a toothed plate 202 is fixedly installed on the fixed plate 201. The glass clamping mechanism 3 includes an air cushion slide rail 301, a clamping frame 302, a side shift plate 303, a one-way drive assembly 305, a clamping seat 306 and a clamping assembly. The clamping frame 302 is slidably installed at the upper end of the air cushion slide rail 301. A notch is opened in the middle of the clamping frame 302. The side shift plate 303 is slidably installed in the notch. A reciprocating lead screw 304 is rotatably installed in the notch. The reciprocating lead screw 304 passes through the side shift plate 303 and is in threaded cooperation with it. The one-way drive assembly 305 is rotatably installed on the clamping frame 302, and the one-way drive assembly 305 is connected to one end of the reciprocating lead screw 304. The clamping seat 306 is fixedly installed at the lower end of the side shift plate 303. The clamping assembly is installed at the bottom of the clamping seat 306, and the clamping assembly can clamp the glass. The test rail 4 can clamp and fix the sealing strip to be tested. The pushing mechanism 5 can push and pull the glass to move along the test rail 4, and the pushing mechanism 5 can measure the force used to push and pull the glass. When the glass moves back and forth, it drives the clamping frame 302 to move back and forth along the air cushion slide rail 301, so that the one-way drive assembly 305 moves back and forth once under the toothed plate 202. The toothed plate 202 can unidirectionally push the one-way drive assembly 305 to rotate. The one-way drive assembly 305 drives the reciprocating lead screw 304 to rotate unidirectionally. The side shift plate 303 moves horizontally under the action of the reciprocating lead screw 304, thereby driving the glass to move horizontally. The pushing mechanism 5 repeatedly pushes and pulls the glass to make a reciprocating movement. Each time the glass makes a reciprocating movement, it moves horizontally by a certain distance. Repeating like this can obtain multiple groups of sliding resistance data with different relative positions of the glass and the inner and outer lips, which is convenient for accurately obtaining the sliding resistance of the sealing strip, without manually changing the position of the glass, and improving the measurement efficiency.

[0030] It further includes a workbench 1, the steam box 2 is fixedly installed at the upper end of the workbench 1, the pushing mechanism 5 includes a bracket 501, a cylinder 502, a force sensor 503 and a fixed frame 504. The bracket 501 is fixedly installed at the upper end of the workbench 1, the cylinder 502 is fixedly installed at the upper end of the bracket 501, the telescopic end of the cylinder 502 penetrates through one side of the steam box 2 to its interior, the force sensor 503 is fixedly installed at the telescopic end of the cylinder 502, the fixed frame 504 is fixedly connected with the force sensor 503, the fixed frame 504 is U-shaped, one end of the glass is inserted into the fixed frame 504, and the fixed frame 504 is fixed to the glass in cooperation with a bolt. The cylinder 502 drives the glass to reciprocate along the test track 4, and the force sensor 503 measures the sliding resistance.

[0031] Embodiment 2, the difference from the above embodiment is that, as Figure 6 , Figure 7 shown, the clamping assembly includes two first rotating shafts 315, two second rotating shafts 316 and a plurality of clamping members. The two first rotating shafts 315 and the two second rotating shafts 316 are symmetrically and rotatably installed on both sides of the clamping seat 306. The clamping member includes a gear 307, a driving rod 308, a linkage rod 309, a clamping arm 310 and a clamping plate 311. The driving rod 308 is fixedly installed on the outer wall of the gear 307. One end of the driving rod 308 is rotatably connected to one end of the clamping arm 310. One end of the linkage rod 309 is rotatably connected to the middle of the clamping arm 310. The clamping plate 311 is fixedly installed at the other end of the clamping arm 310. Each gear 307 is fixedly connected to the corresponding first rotating shaft 315, and a plurality of gears 307 on the same first rotating shaft 315 are equidistantly arranged. The other ends of the respective linkage rods 309 are fixedly connected to the corresponding second rotating shafts 316. The corresponding two gears 307 are meshed. Rotating one of the gears 307 drives the other gear 307 to rotate in the opposite direction. The driving rod 308 drives the clamping arm 310 to rotate along the first rotating shaft 315. The linkage rod 309 limits the rotation of the clamping arm 310 to prevent the clamping arm 310 from swinging by itself. One ends of the two clamping arms 310 approach each other, and the clamping plate 311 clamps the glass. This structure can drive a plurality of clamping members to clamp the glass at one time, which is convenient to operate and has a good clamping effect.

[0032] One end of the clamping seat 306 is rotatably installed with a second pawl 313, the second pawl 313 cooperates with one of the gears 307, one end of the clamping seat 306 is fixedly installed with a second leaf spring 314, one end of the second leaf spring 314 contacts the inner side surface of the second pawl 313, a knob 312 is fixedly installed on one of the gears 307, rotating the knob 312 can conveniently drive the gear 307 to rotate. The setting of the second pawl 313 enables the gear 307 to rotate only in one direction, achieving a one-way locking effect on the gear 307, preventing the clamping member from bouncing outward after clamping the glass, and ensuring the glass clamping effect.

[0033] One side of the clamping plate 311 is fixedly installed with an anti-slip pad 317, and the anti-slip pad 317 is provided with anti-slip lines on one side, increasing the friction with the glass, thereby increasing the firmness of clamping.

[0034] Example 3, the difference from the above example is that as Figure 8 shown, the one-way drive assembly 305 includes a turntable 3051, an internal ratchet 3052, a first pawl 3053 and a first leaf spring 3054. The turntable 3051 is fixedly installed at one end of the reciprocating lead screw 304. The internal ratchet 3052 is rotatably installed on the clamping frame 302. The internal ratchet 3052 is coaxially arranged with the turntable 3051. The first pawl 3053 is rotatably installed on the outer wall of the turntable 3051, and the first pawl 3053 cooperates with the internal ratchet 3052. The first leaf spring 3054 is fixedly installed on the outer wall of the turntable 3051. One end of the first leaf spring 3054 contacts the inner side surface of the first pawl 3053. When the internal ratchet 3052 rotates towards the side that triggers the first pawl 3053, the turntable 3051 is driven to rotate through the first pawl 3053, thereby driving the reciprocating lead screw 304 to rotate, and then the side shift plate 303 can be driven to move. In the reverse direction, the side shift plate 303 is not driven to move.

[0035] The outer wall of the internal ratchet 3052 is provided with first tooth patterns, and the lower end of the tooth pattern plate 202 is provided with second tooth patterns. The first tooth patterns are meshed with the second tooth patterns. When the internal ratchet 3052 moves below the tooth pattern plate 202, the internal ratchet 3052 rotates, and the turntable 3051 is selectively driven to rotate according to the rotation direction, ensuring that the glass clamping mechanism 3 moves back and forth once below the tooth pattern plate 202, and the glass is laterally displaced by a certain distance.

[0036] One end of the fixing plate 201 is provided with a plurality of mounting holes 203. Both ends of the toothed plate 202 are symmetrically and fixedly installed with threaded rods 204. The two threaded rods 204 penetrate through the corresponding mounting holes 203, and one end of each of the two threaded rods 204 is fitted with a nut 205. By installing the threaded rods 204 in different mounting holes 203, the relative position between the toothed plate 202 and the fixing plate 201 can be changed, thereby changing the length of the relative sliding between the inner ratchet 3052 and the toothed plate 202, and thus changing the distance that the glass traverses horizontally after one round trip. The shorter the distance that the glass traverses horizontally each time, the more times it needs to move from one side to the other side, the more sliding resistance data can be obtained, and the more accurate the measurement result is. According to the required measurement accuracy, the installation position of the toothed plate 202 can be selected.

[0037] The bottom of the steam box 2 is externally connected with a steam inlet pipe. A bottom plate 206 is fixedly installed at the bottom inside the steam box 2. A plurality of air holes are uniformly arranged on the bottom plate 206, so that steam can enter the steam box 2 evenly, ensuring that the temperature is consistent everywhere inside the steam box 2 and avoiding affecting the detection effect.

[0038] Working principle:

[0039] Install the seal strip to be tested in the test track 4, insert the bottom of the glass into the seal strip to be tested, and the top of the glass fits against the lower end of the clamping seat 306. Twist the knob 312 to drive one of the gears 307 to rotate, and the other gear 307 rotates in the opposite direction accordingly. The driving rod 308 drives the clamping arm 310 to rotate along the first rotating shaft 315. The linkage rod 309 limits the rotation of the clamping arm 310 to prevent the clamping arm 310 from swinging by itself. One ends of the two clamping arms 310 approach each other, driving the clamping plate 311 to contact both sides of the glass and clamp the glass.

[0040] The driving cylinder 502 pushes the glass to perform a reciprocating motion along the test track 4. The force sensor 503 measures the sliding resistance. When pushing the glass forward, the inner ratchet 3052 contacts the toothed plate 202 and rotates in the direction of compressing the first leaf spring 3054 under the action of the toothed plate 202. The first pawl 3053 does not act on the turntable 3051, and the turntable 3051 does not rotate. When pulling the glass back, the inner ratchet 3052 contacts the toothed plate 202 again and rotates in the direction of the rebound of the first pawl 3053. The turntable 3051 is driven to rotate through the first pawl 3053, thereby driving the reciprocating lead screw 304 to rotate, driving the side shift plate 303 to move horizontally in a direction perpendicular to the air cushion slide rail 301, driving the entire clamping assembly to move horizontally, and the glass moves with the clamping assembly, changing its position in the seal strip.

[0041] Repeat the above operation so that after the glass longitudinally moves along the air cushion slide rail 301 reciprocally once, it will laterally move a certain distance in the direction perpendicular to the air cushion slide rail 301 until the side shift plate 303 moves from one end of the reciprocating lead screw 304 to the other end, and the lateral movement distance of the glass in the sealing strip reaches the maximum. Measure the sliding resistance of the glass at different positions in the sealing strip;

[0042] By injecting steam into the steam box 2 to change the temperature inside the steam box 2, and when the temperature is stable, continue to drive the cylinder 502 to push the glass to move reciprocally. The side shift plate 303 starts to move back from the other end of the reciprocating lead screw 304 until the side shift plate 303 moves back to the initial position. Measure the sliding resistance of the glass at different positions in the sealing strip after changing the temperature;

[0043] After repeating the above operation to obtain multiple groups of data, by comparing the sliding resistance of the glass at different positions in the sealing strip at the same temperature and the sliding resistance of the glass at the same position in the sealing strip at different temperatures, the influence of temperature and the position of the glass in the sealing strip on the sliding resistance of the sealing strip is obtained. The whole process does not require manual operation, which not only saves manpower and improves the measurement efficiency, but also excludes the interference of human factors on the detection data and improves the accuracy of the data;

[0044] After the detection is completed, dial the second pawl 313 outwards and reverse-rotate the knob 312 to drive one ends of the two clamping arms 310 to move away from each other, and the clamping plate 311 disengages from the glass surface, facilitating the removal of the glass;

[0045] If more groups of sliding resistance of the glass at different positions in the sealing strip are needed, the relative position of the toothed plate 202 and the fixed plate 201 can be changed, that is, the length of the relative sliding between the internal ratchet 3052 and the toothed plate 202 during the reciprocating movement of the glass, so as to change the lateral movement distance of the glass after reciprocating movement once. The shorter the length of the relative sliding between the internal ratchet 3052 and the toothed plate 202, due to the fixed length of the reciprocating lead screw 304, the lateral movement range of the glass is fixed, the shorter the single lateral movement distance of the glass, the more times it needs to move from one side to the other side, the more sliding resistance data is obtained, and the more accurate the measurement result is. Select the installation position of the toothed plate 202 according to the required measurement accuracy.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

One end of the second leaf spring contacts the inner side of the second pawl. A knob is fixedly installed on one of the gears; The outer wall of the internal ratchet is provided with a first tooth pattern. The lower end of the toothed plate is provided with a second tooth pattern. The first tooth pattern is meshed with the second tooth pattern; The test rail can clamp and fix the seal strip to be tested. The pushing mechanism can push and pull the glass to move along the test rail, and the pushing mechanism can measure the force used to push and pull the glass. When the glass moves back and forth, it drives the clamping frame to move back and forth along the air cushion slide rail, so that the one-way driving component moves back and forth once under the toothed plate. The toothed plate can unidirectionally push the one-way driving component to rotate, and the one-way driving component drives the reciprocating lead screw to rotate unidirectionally. The side shift plate moves horizontally under the action of the reciprocating lead screw, thereby driving the glass to move horizontally. The pushing mechanism repeatedly pushes and pulls the glass to make reciprocating movements. Each time the glass makes a reciprocating movement, it moves horizontally by a certain distance. By repeating this way, multiple sets of sliding resistance data with different relative positions between the glass and the inner and outer lips can be obtained.
