Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat fabric processing, in particular to a friction fastness testing device for automobile seat fabric. Background Art

[0002] Car seats are a crucial component of a vehicle's interior, providing not only seating space but also comfort, safety, and functionality. Car seat design typically adheres to ergonomic principles to ensure stability and comfort for passengers while driving. The basic structure of a seat includes the main frame, seat cushion, backrest, and headrest, and can vary in design and configuration depending on the vehicle model and intended use. Car seat manufacturing requires specialized fabrics, which undergo wear resistance testing during production.

[0003] In existing technologies, wear resistance testing usually involves fixing a fabric sample of a certain size on a test bench, ensuring the stability of the sample during the test using a special clamp, and then repeatedly rubbing the sample using a testing device (such as a friction head) to simulate the wear during use. However, under the action of friction, the fibers of the fabric will gradually break, forming tiny fiber fragments, namely dust. This dust not only reduces the cleanliness of the test environment, but also may cause damage to the respiratory system of the test personnel, increasing the risk of respiratory diseases.

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] like Figure 1 and Figure 3 As shown, this embodiment proposes a friction fastness test device for automobile seat fabrics, including a base plate 1, a test bench 2 is slidably connected to the top of the base plate 1, a fixture 3 is fixedly connected to the front of the top of the test bench 2, a mounting frame 4 is fixedly connected to the rear of the top of the base plate 1, a plurality of friction heads 5 are rotatably connected to the front of the mounting frame 4, a weight 6 is slidably connected to the top of the friction head 5, a mounting box 7 is fixedly connected to the right side of the top of the base plate 1, a fan 8 is provided on the right side of the mounting box 7, a filter screen 9 is fixedly connected to the inside of the mounting box 7, and a servo motor is fixedly connected to the top of the mounting box 7. Motor 10, the output end of the servo motor 10 is fixedly connected to a swing ball 11, two slide rods 12 are fixedly connected to the inner wall on the left side of the installation box 7, and a spring 13 is sleeved on the outside of the two slide rods 12. A movable plate 14 is slidably connected to the outside of the two slide rods 12, and a collision ball 15 is fixedly connected to the right side of the movable plate 14. A collecting box 16 is slidably connected inside the installation box 7 and below the filter 9. An exhaust pipe 17 is fixedly connected to the top of the installation box 7, and a plurality of suction heads 18 are fixedly connected to the bottom of the exhaust pipe 17. A fixed component is provided on the left side of the friction head 5. The purpose of this setting is that when it is necessary to conduct a wear resistance test on the fabric, the fabric of a specific size is placed on the test bench 2, and then fixed by the clamp 3. It is started by the control panel to drive the test bench 2 to move back and forth to test the fabric. In order to avoid dust pollution of the working environment during the test, the exhaust pipe 17 and the suction head 18 are driven to work by starting the fan 8, and the dust generated by the friction of the fabric is adsorbed and filtered through the filter 9. The filtered air is discharged through the fan 8, avoiding dust flying and affecting the working environment. At the same time, the servo motor 10 drives the pendulum ball 11 to rotate intermittently. The rotation of the pendulum ball 11 drives the moving plate 14. Under the elastic action of the spring 13, the impact ball 15 regularly beats the filter 9, effectively avoiding the accumulation of dust on the filter 9, ensuring the continuous and efficient filtering effect, and the beaten dust will fall into the collection box 16 below. The collection box 16 can be taken out by pulling the handle.

[0025] Preferably, one end of spring 13 is fixedly connected to the inner wall of the installation box 7, and the other end of spring 13 is fixedly connected to the left side of the movable plate 14. The purpose of this arrangement is to ensure the stability of spring 13 in the system, so that it can accurately transmit force, and at the same time, after the impact ball 15 hits the filter 9, it can be quickly reset.

[0026] Preferably, the top of the pendulum ball 11 is rotatably connected to the top wall of the installation box 7. The purpose of this arrangement is that the pendulum ball 11 is freely and stably rotated, ensuring that it can efficiently and accurately drive the movable plate 14 under the drive of the servo motor 10, and then regularly beat the filter screen 9 through the impact ball 15.

[0027] Preferably, the swing ball 11 is in contact with the movable plate 14, and the impact ball 15 is in contact with the filter screen 9. The purpose of this arrangement is that the abutment design between the swing ball 11 and the movable plate 14 ensures that the energy when the servo motor 10 drives the swing ball 11 to rotate can be effectively transferred to the movable plate 14, and then the filter screen 9 is hit by the impact ball 15. The precise abutment between the impact ball 15 and the filter screen 9 ensures that each hit can accurately act on the filter screen 9, effectively removing accumulated dust, avoiding clogging of the filter screen 9, and maintaining its efficient filtering performance.

[0028] Example 2

[0029] like Figure 2 and Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a fixing assembly including a frame 19, the right side of the frame 19 is fixedly connected to the left side of the friction head 5, a pressing rod 20 is slidably connected inside the frame 19, a fixing rod 21 is fixedly connected to the left inner wall of the frame 19, an external side of the fixing rod 21 is slidably connected to a plug-in rod 22, a spring 23 is sleeved on the external side of the fixing rod 21, and a connecting rod 24 is provided between the plug-in rod 22 and the pressing rod 20. The purpose of this setting is that when different pressures need to be applied to the friction head 5, the pressing rod 20 is pressed to drive the connecting rod 24 to rotate, and then the plug-in rod 22 is driven to slide toward the fixed rod 21 and squeeze the spring 23 until the plug-in rod 22 is completely separated from the inside of the weight 6, the weight 6 is taken out, and the new weight 6 is inserted into the friction head 5. The pressing rod 20 is released, and the plug-in rod 22 is driven to move under the action of the spring 23, and the connecting rod 24 is driven to rotate, so that the pressing rod 20 returns to its original position until the plug-in rod 22 is fully inserted into the weight 6 to complete the installation.

[0030] Preferably, one end of the plug-in rod 22 passes through the friction head 5 and is inserted into the inside of the weight 6. The purpose of this setting is to ensure that during the test, the weight 6 can stably apply a predetermined pressure and will not be displaced or loosened due to external force, thereby ensuring the accuracy and reliability of the test results.

[0031] Preferably, one end of the connecting rod 24 is hinged to the top of the plug-in rod 22, and the other end of the connecting rod 24 is hinged to the bottom of the pressing rod 20. The purpose of this setting is that when the operator presses the pressing rod 20, the connecting rod 24 can accurately transmit the force to the plug-in rod 22, triggering the movement of the plug-in rod 22, and thereby achieving connection or separation with the weight 6.

[0032] Preferably, one end of spring 23 is fixedly connected to the inner wall of the frame 19, and the other end of spring 23 is fixedly connected to the left side of the plug-in rod 22. The purpose of this arrangement is to enable spring 23 to store energy when the plug-in rod 22 is pushed. When the external force is removed, the elastic restoring force of spring 23 can quickly reset the plug-in rod 22, thereby ensuring the stability and reliability of the connection mechanism between the plug-in rod 22 and the weight 6.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
