Description

Technical Field

[0001] The utility model relates to the technical field of automobile interior carpet detection, in particular to a vehicle interior carpet surface wear resistance testing device. Background Art

[0002] The car interior carpet is placed inside the car for users to step on, which has the function of increasing the comfort of the user's feet.

[0003] In the prior art, a Chinese patent with publication number "CN209764632U" discloses a wear resistance testing device for automobile interior carpets. By setting a servo motor, a No. 1 telescopic sleeve and a No. 1 cylinder, the No. 1 cylinder drives the grinding disc to contact the automobile interior carpet through the No. 1 telescopic sleeve. When the servo motor is running again, it can drive the grinding disc to grind the automobile interior carpet. There is no need for manual grinding, which effectively saves labor costs and improves work efficiency. By setting a metal mesh, a connecting pipe and a dust box, after grinding, the fan starts to run. The wind force generated by the fan sends the dust under the metal mesh, and the dust enters the connecting pipe and the dust box, so the dust can be recovered, which effectively solves the problem of dust polluting the air and affecting the physical and mental health of the staff, and solves the problem that when performing wear resistance tests on automobile interior carpets, agents need to use grinding discs to grind the automobile interior carpets, and this method has slow grinding efficiency.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] When conducting wear resistance tests on motor vehicle interior carpets, most of them rely on manual use of rough friction blocks or rollers to rub for a certain period of time to obtain data on the wear resistance of the fabric in a shorter period of time. However, this testing method has low efficiency. When conducting tests of different wear resistances, personnel need to conduct multiple tests and apply different forces each time to effectively test the wear resistance of the motor vehicle interior carpet surface. In order to avoid this phenomenon, the motor vehicle interior carpet surface is now tested for wear resistance through a designated testing device. However, the current wear resistance test cannot adjust the position of the test block, resulting in the need to wait for the motor vehicle interior carpet surface to return to its original state after the first wear resistance test is completed before the second wear resistance test can be performed. After the second wear resistance test is completed, since the first wear resistance test mark cannot be retained on the motor vehicle interior carpet surface for a long time, personnel cannot compare the two test results.

The sliding groove 22 is arranged on the adjustment block 8. A sliding block 12 is movably mounted on the threaded rod 11. The sliding block 12 is slidably mounted inside the sliding groove 22.

[0030] The test assembly includes a mounting plate 13 and a detection block 14. The surface of the detection block 14 is not a smooth surface. The surface of the detection block 14 can be adjusted according to personnel needs. A connecting plate 15 is fixedly installed on the mounting plate 13.

[0031] A limit slide bar 18 is fixedly mounted on the detection block 14, the top end of the limit slide bar 18 passes through the mounting plate 13, and is slidably mounted with the mounting plate 13. The cross-sectional shape of the limit slide bar 18 is T-shaped, and the limit slide bar 18 ensures that the detection block 14 does not rotate when being adjusted;

[0032] A pressing assembly is provided on the positioning plate 4, and the interior carpet 2 is fixed in position by the pressing assembly; the pressing assembly includes a third electric push rod 19, and the third electric push rod 19 is fixedly mounted on the positioning plate 4, and a pressing plate 20 is fixedly mounted on the output shaft of the third electric push rod 19, and the position of the pressing plate 20 is between the positioning plate 4 and the workbench 1.

[0033] In this embodiment, the interior carpet 2 is fixed in position by a pressing assembly to ensure that the interior carpet 2 is in a taut state, and then the detection block 14 in the detection assembly is driven by the driving assembly to contact the surface of the interior carpet 2, and the friction force applied by the detection block 14 to the interior carpet 2 is adjusted by rotating the adjusting screw 17, and the detection block 14 is driven by the driving assembly to move on the surface of the interior carpet 2. At the same time, the position of the detection block 14 is adjusted by adjusting the screw 17 to perform multiple tests, and the wear resistance of the interior carpet 2 can be completed by observing the two surfaces of the interior carpet.

[0034] Embodiment two:

[0035] On the basis of Example 1, in order to facilitate personnel to observe the wear resistance of the two surfaces of the interior carpet more intuitively, this effect can be achieved by adjusting the detection block 14 at different positions on the two surfaces of the interior carpet through the adjustment component. This effect is achieved by adjusting the component. The adjustment component includes a first electric push rod 6, a second electric push rod 7 and an adjustment block 8. When the first electric push rod 6 and the second electric push rod 7 are working, the output shafts between the two electric push rods are making opposite movements.

[0036] In this embodiment, when the driving component drives the detection block 14 to complete the wear resistance test on the surface of the interior carpet 2 in sequence, the position of the moving block in the moving groove 5 is adjusted by adjusting the opposite movements of the first electric push rod 6 and the second electric push rod 7 in the component, so that the detection block 14 is adjusted to another position on the surface of the interior carpet 2, and then the friction force applied by the detection block 14 to the surface of the interior carpet 2 is adjusted to complete the second wear resistance test. By observing the different degrees of wear resistance tests on the two surfaces of the interior carpet, personnel can intuitively observe the different degrees of wear resistance on the two surfaces of the interior carpet.

[0037] Working principle:

[0038] When in use, the motor vehicle interior carpet 2 to be tested is laid flat on the workbench 1, and the pressing plate 20 is pressed and fixed on the surface of the motor vehicle interior carpet 2 by driving the third electric push rod 19, and then the adjusting screw 17 is rotated, and the detection block 14 is adjusted by the rotation of the bearing 16 and the limited sliding of the limit slide rod 18, thereby completing the adjustment of the detection block 14, and the friction force applied by the detection block 14 to the motor vehicle interior carpet 2 is adjusted by the rotation of the adjusting screw 17, and then the threaded rod 11 is driven to rotate by the motor vehicle 10, and the threaded rod 11 drives the sliding block 12 to slide in the sliding groove 22 when rotating, and the sliding of the sliding block 12 causes the adjustment block 8 to leave a friction mark on the surface of the motor vehicle interior carpet 2, completing the first wear resistance test;

[0039] At this time, the original position is restored by adjusting the screw rod 17, and then the first electric push rod 6 and the second electric push rod 7 are driven. At this time, when the first electric push rod 6 and the second electric push rod 7 are working, the output shafts between the two electric push rods are doing opposite movements, which is convenient for adjusting the position of the adjustment block 8 in the moving groove 5, so that the adjustment block 8 is not in the previous position, and then the friction force of the detection block 14 on the two surfaces of the motor vehicle interior carpet is adjusted by adjusting the screw 17. The friction force adjusted for the second time is different from the friction force adjusted for the first time. The threaded rod 11 is driven to rotate by the motor vehicle 10, and the detection block 14 is driven by the sliding block 12 to leave a second mark on the two surfaces of the motor vehicle interior carpet, thereby completing the second wear resistance test;

[0040] By observing the two marks on the two sides of the motor vehicle interior carpet, personnel can intuitively observe the results of the wear resistance test of the two sides of the motor vehicle interior carpet.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
