Technical Field
[0001] The present invention relates to the technical field of smart sleeping bag production quality testing, and in particular to a quality testing device and a testing method for a smart sleeping bag. Background Art
[0002] The smart sleeping bag is an innovative product that combines modern technology with traditional sleeping bag design. It aims to provide a more comfortable, safe and convenient sleeping experience. The smart sleeping bag is equipped with a heating module and other testing modules to monitor the sleeper's vital signs. The outer material of the smart sleeping bag is mainly cloth. Since sleeping bags are mainly used outdoors, the wear resistance of the smart sleeping bag is tested.
[0003] Currently, a commonly used wear resistance testing device is a friction testing machine. This device consists of a friction head, a pad, and a fixed clamp. The production fabric of the sleeping bag is placed on the pad and then fixed by the clamp. The friction head is then pressed against the fabric. The wear resistance of the sleeping bag is tested by the back-and-forth movement of the friction head. For example, Publication No. CN109283080A discloses a fabric wear resistance testing machine, which includes a base, a sleeve, a slide rod, a first spring, a horizontal slider, a movable plate, an N-shaped frame, a vertical slider, a second spring, a cross plate, a guide wheel, a first support plate, a first bearing seat, a screw rod, a roller, a drive motor, an arc-shaped pressure block, a material, a guide rod, a push plate, an elastic plate, a contact block, a third spring, and a clamping rod. Two sleeves are symmetrically fixed on the front and back sides of the right side of the top of the base, and a sliding rod is provided in the sleeve. A first spring is connected between the bottom end of the sliding rod and the bottom of the sleeve. A movable plate is provided above the sliding rod, and horizontal sliding grooves are symmetrically opened on the front and back sides of the bottom of the movable plate. A horizontal sliding block is provided in the horizontal sliding groove to match it. The horizontal sliding block slides in the horizontal sliding groove, and the bottom of the horizontal sliding block is fixedly connected to the top of the sliding rod. Materials of different roughness are evenly spaced and fixed on the top of the movable plate. First support plates are symmetrically fixed on the front and back sides of the right side of the top of the base, and the first support plates on the front and back sides are located on the outside of the front and back sleeves.
[0004] The wear resistance testing machine can perform a wear resistance test by putting a cloth on an arc-shaped pressure block and fixing it, and starting a drive motor to rub the cloth on the material. There is no need for people to hold the cloth and rub it on the material, which saves time and effort, and the test speed is faster. The test frequency is also consistent and the test is accurate. Through the drive device, there is no need for people to manually move the movable plate, which is convenient and quick. Through the action of the second protrusion, there is no need for people to pull the horizontal plate upward, which improves work efficiency.
[0005] However, when using this wear resistance testing machine, it can only test the wear resistance of the fabric under normal conditions, and its use has certain limitations. The wear resistance test of the fabric needs to be tested under a variety of different tension states. Because the thermal insulation cotton in the sleeping bag will support the fabric, making the tension of the fabric greater than the tension in the natural state, the data and results obtained from the test have limitations and are not enough to represent the overall wear resistance of the sleeping bag.
[0006] Therefore, a novel quality testing device and testing method for intelligent sleeping bags can be used to solve the shortcomings of the prior art. Summary of the Invention

[0017] The present invention also provides a quality testing method for a smart sleeping bag, comprising the quality testing device for the smart sleeping bag, and further comprising the following steps: S1. Fix the fabric by first flattening the fabric and placing it on the top of the two placement cylinders. Then press the fabric into the gap between the two placement cylinders. Then, lock the fabric with the locking assembly so that the fabric is close to the outer surface of the placement cylinders. S2. Adjust the friction block. Use the lifting assembly to adjust the height of the friction block so that the friction block contacts the fabric. During adjustment, the pressure between the fabric and the friction block needs to be controlled. S3. After the height of the friction block is adjusted, the driving assembly is used to move the friction block. The movement of the friction block causes friction on the fabric, thereby performing a wear resistance test. After a certain frequency of testing, the test position is changed by the transposition assembly to perform multi-point testing. S4. As the driving component operates, the inflation component will be driven to operate and inflate the placement tube. The inflation component is used to adjust the tension of the fabric. After the tension adjustment is completed, the driving component needs to continue to operate, so the synchronization component needs to be started. Under the action of the synchronization component, the tension is guaranteed to remain unchanged for friction testing. At the same time, the inflation component can also perform multi-tension adjustment to perform multi-tension testing. Multi-point testing and multi-tension testing require at least nine tests to provide more accurate test results.
[0018] Compared with the existing technology, the advantages of the present invention are: 1. When conducting a wear resistance test, the quality testing device for this smart sleeping bag can freely change the upper and lower positions of the friction protrusions by setting motor 2, screw 2, and threaded sleeve 2, so that the pressing force between the friction protrusions and the fabric remains constant. Then, in conjunction with the motor and belt, the pressing roller can be driven to rotate, thereby changing the test position. In this way, multi-point testing is carried out and the average value is selected. The test results are more convincing and more accurate.
[0019] 2. When conducting a wear resistance test, the quality testing device for this smart sleeping bag can change the position of the pressure roller by setting an inflatable component and a wedge block, and change the tension of the fabric through the pressure roller, so as to conduct a wear resistance test on the fabric at different tensions, and the measured data is more practical.
[0020] 3. When conducting a wear resistance test, the quality testing device for this smart sleeping bag uses motor three and screw one to drive the rubber gas tank to move after the abutment plate and the rubber gas tank abut against each other, so that the moving speed of the rubber gas tank is consistent with the moving speed of the friction bump. This ensures that the tension of the fabric is consistent, and realizes the controlled variable method test.
[0021] In summary, during the wear resistance test of the smart sleeping bag, the present invention can not only automatically perform multi-point constant pressure transposition testing to improve the accuracy of the test, but also perform multi-tension testing and keep the tension constant during the test, further improving the accuracy of the test, and the measured data is more representative and more practical.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.
[0025] Example 1: Reference Figure 1-Figure 4 、 Figure 8 、 Figures 11-17 , a quality testing device for a smart sleeping bag, comprising a base 1 and a fabric 28; The placement part is installed on the base 1. The placement part includes two placement cylinders 32, a locking assembly and a shifting assembly. The locking assembly is used to lock the cloth 28 placed on the placement cylinder 32. The shifting assembly is used to perform a shifting test on the cloth 28 to facilitate wear resistance testing at different positions.
[0026] The locking assembly includes a pad 3 fixedly mounted on the base 1, and the two placement cylinders 32 are fixedly connected to the pad 3. A plurality of screws 34 are fixedly mounted on the pad 3, and a locking frame 33 that cooperates with the fabric 28 is slidably mounted on the plurality of screws 34. The locking frame 33 and the screws 34 are fixed by nuts 35, and a plurality of balls 45 are provided at the position where the locking frame 33 contacts the fabric 28.
[0027] First, the fabric 28 is flattened and placed on the upper part of the two placement cylinders 32, and then the fabric 28 is pressed into the gap between the two placement cylinders 32. Next, the locking frame 33 is sleeved on the screw 34, and the locking frame 33 is pressed between the two placement cylinders 32. The locking frame 33 is then fixed with the nut 35 so that the locking frame 33 presses the fabric 28 onto the placement cylinders 32, thereby completing the fixing of the fabric 28. In order to reduce the friction between the locking frame 33 and the cloth 28 , a rolling ball 45 is provided at the contact point between the edge of the locking frame 33 and the cloth 28 , which can effectively protect the cloth 28 .
[0028] The shifting assembly includes a limit plate 38 fixedly mounted inside the placement cylinder 32, a roller frame 40 is slidably mounted on the limit plate 38, a pressure roller 36 that cooperates with the cloth 28 is rotatably mounted on the roller frame 40, the pressure roller 36 passes through and extends out of the top of the placement cylinder 32, a motor 39 is fixedly mounted on the roller frame 40, and the driving end of the motor 39 is connected to the pressure roller 36 by a belt 37.
[0029] During the test process, after the test of one part is completed, a position change test is required. At this time, the motor 39 needs to be started. The driving end of the motor 39 drives the pressure roller 36 to rotate through the belt 37. Since the pressure roller 36 and the cloth 28 are in contact with each other and the pressure is large, the friction between the pressure roller 36 and the cloth 28 is large at this time. The rotation of the pressure roller 36 will drive the cloth 28 to move on the pressure roller 36, thereby realizing the replacement of the test part of the cloth 28, so that the wear resistance test can be performed on different positions of the cloth 28.
[0030] The placement tube 32 adopts a semicircular arc design and has a through hole at the top. The pressing roller 36 extends from the inside of the placement tube 32 through the through hole to press against the cloth 28 outside the placement tube 32.
[0031] Example 2: This example differs from the example 1 in that: Figure 1-Figure 7 The test part is installed on the base 1, and the test part includes a friction protrusion 18, a lifting assembly and a driving assembly. The driving assembly is used to drive the lifting assembly to move, and the lifting assembly is used to control the pressing force between the friction protrusion 18 and the cloth 28.
[0032] The cross-section of the friction block 18 is semicircular, and the end face of the pressing roller 36 is circular. Therefore, when the friction block 18 moves, the test portion of the tested fabric 28 is linear, which can effectively reduce the contact area between the friction block 18 and the fabric 28, thereby speeding up the friction test efficiency. Since the contact area is small and the friction force is small, it is difficult to drive the fabric 28 to move when the friction block 18 moves. This ensures that the fabric 28 is in a straight state during the test, avoids wrinkles in the fabric 28, and allows the friction test to proceed smoothly.
[0033] The lifting assembly includes a third bracket 6 fixedly mounted on the base 1, a sliding rail 19 fixedly mounted on the third bracket 6, a plurality of sliding blocks 20 slidably mounted on the sliding rail 19, a support plate 21 fixedly mounted on the plurality of sliding blocks 20, a motor 2 9 fixedly mounted on the support plate 21, and a screw rod 2 rotatably mounted on the support plate 21, a threaded sleeve 2 threadedly rotatably mounted on the screw rod 22, a movable plate 23 slidably mounted on the support plate 21, the movable plate 23 and the threaded sleeve 2 are fixedly connected, a pressure sensor 24 is fixedly mounted on the bottom of the movable plate 23, a connecting plate 25 is fixedly mounted on the bottom of the pressure sensor 24, and the friction protrusion 18 and the connecting plate 25 are fixedly connected by a snap-fit.
[0034] After the fabric 28 is fixed, the screw rod 22 is driven to rotate by the motor 29, thereby driving the threaded sleeve 2 and the movable plate 23 to move on the support plate 21 until the friction protrusion 18 and the fabric 28 are in contact with each other. At this time, the pressure sensor 24 is used to sense the pressing force between the friction protrusion 18 and the fabric 28, and then the controller controls the forward and reverse rotation of the motor 29 to ensure that the pressure between the friction protrusion 18 and the fabric 28 is constant, so as to perform a constant pressure test.
[0035] The driving assembly includes a first bracket 2 fixedly mounted on the base 1, a motor 7 and a reducer 12 fixedly mounted on the first bracket 2, the driving end of the motor 7 is connected to the reducer 12, a rotating disk 8 is fixedly mounted on the driving end of the reducer 12, an eccentric pillar is fixedly mounted on the rotating disk 8, a rotating rod 17 is rotatably mounted on the pillar, and the rotating rod 17 is rotatably connected to the mounting plate 13.
[0036] The driving end of the motor 7 rotates, and after being decelerated by the reducer 12, it drives the rotating disk 8 to rotate, thereby driving the pillar to rotate eccentrically. The pillar drives the rotating rod 17 to rotate, and the rotating rod 17 drives the mounting plate 13 to move horizontally, thereby driving the friction protrusion 18 to move, and performing a horizontal movement friction test; The length of the rotating rod 17 can be adjusted according to the position of the pillar. By replacing the rotating disk 8 with different diameters, the position of the pillar is different, and the circumferential length of the eccentric rotation of the pillar is different. Therefore, the horizontal displacement stroke of the friction protrusion 18 is different, which is suitable for friction tests of different lengths; the function of the reducer 12 is to reduce the moving speed of the friction protrusion 18, thereby reducing the friction frequency, allowing the fabric 28 to dissipate heat faster, avoiding the influence of high temperature on the friction test, so that the friction test can be performed more accurately.
[0037] Example 3: This example differs from the technical solution of Example 2 in that: Figure 1-Figure 4 、 Figures 8-10 The adjusting part is installed on the base 1 and cooperates with the testing part to adjust the tension of the cloth 28. The adjusting part includes an inflation component and a synchronization component. The inflation component is used to inflate the placement tube 32. The synchronization component cooperates with the driving component to control the inflation amount so that the tension of the cloth 28 reaches different levels.
[0038] The inflation assembly includes a push plate 26 fixedly mounted on the support plate 21, a mounting plate 13 fixedly mounted on the push plate 26, a plurality of adjustable telescopic rods 15 fixedly mounted on the mounting plate 13, and a resist plate 14 fixedly mounted on the telescopic ends of the plurality of adjustable telescopic rods 15. A second bracket 5 is mounted on the base 1 through a limiting slide rail 4, and two rubber gas tanks 29 matching the resist plate 14 are fixedly mounted on the second bracket 5. The two rubber gas tanks 29 are connected to the corresponding placement tube 32 through an air guide tube 30, and two partitions 44 are fixedly mounted in the two placement tubes 32. A piston plate 43 is slidably mounted in the chamber between the two partitions 44, and the air guide tube 30 is inserted into the interior of the chamber. An adjustment mechanism is installed between the piston plate 43 and the roller frame 40.
[0039] The two partitions 44 are located on the same side of the placement cylinder 32 and are not connected to the through hole. A closed cavity is formed between the two partitions 44, and the piston plate 43 moves in the cavity between the two partitions 44; The movement of the mounting plate 13 will drive the push plate 26 to move, thereby driving the push plate 14 to move by adjusting the telescopic rod 15. The push plate 14 will abut against the rubber gas tank 29, which will compress the rubber gas tank 29 and press the air in the rubber gas tank 29 into the cavity between the two partitions 44 through the air guide tube 30. The air guide tube 30 is located on the right side of the piston plate 43 (the right side of this position refers to the reference position of the piston plate 43). Figure 15 ), so that the pressure on the left side of the piston plate 43 increases, thereby pushing the piston plate 43 to move to the left, thereby completing the inflation operation.
[0040] During the inflation process, the mounting plate 13 is constantly moving and moves at a curved rate rather than a linear rate. The moving speed of the mounting plate 13 is constantly changing. In order to stabilize the pressure in the chamber, it is necessary to drive the rubber gas tank 29 to move together with the mounting plate 13 (the role of the synchronization component). However, since the movement of the mounting plate 13 is constant, in order to achieve different inflation effects, it is necessary to adjust the compression degree of the rubber gas tank 29 by adjusting the telescopic rod 15, thereby adjusting the pressure in the chamber.
[0041] The adjusting mechanism includes a wedge block 42 slidably mounted inside the placement cylinder 32, a push rod fixedly mounted on the wedge block 42, the push rod and the piston plate 43 are fixedly connected, and the push rod and one of the partitions 44 are through-slidingly connected, and a pressure wheel 41 that cooperates with the wedge block 42 is rotatably mounted at the bottom of the roller frame 40.
[0042] The increase in pressure in the chamber will push the piston plate 43 to move, thereby driving the push rod and the wedge block 42 to move. The wedge block 42 moves to the left, pushing the pressure wheel 41 upward, thereby changing the height of the pressure roller 36. Since both sides of the cloth 28 are locked by the locking frame 33, the upward movement of the pressure roller 36 will increase the tension of the cloth 28, thereby performing friction tests with different tensions.
[0043] The synchronization component includes a motor 3 10 fixedly mounted on the base 1, a screw 16 is mounted on the driving end of the motor 3 10, a threaded sleeve 31 is threadedly mounted on the screw 16, the threaded sleeve 31 is fixedly connected to the second bracket 5, the screw 16 is rotationally connected to the base 1 through a fixed block 27, and a controller is connected to the pressure sensor 24, which controls the motor 3 10.
[0044] The pressing roller 36 moves further as the pressure increases, thereby increasing the pressure between the pressing roller 36 and the friction bump 18. At this time, the height of the friction bump 18 needs to be adjusted to keep the pressure constant. A pressure sensor is installed on the pressing roller 36 to sense the pressure between the pressing roller 36 and the fabric 28, thereby controlling the tension of the fabric 28. At the same time, the pressure sensor controls the operation of the motor 3 10 through the control module. The driving end of motor three 10 rotates to drive screw one 16 to move, and under the action of threaded sleeve one 31, it drives the second bracket 5 and the rubber gas tank 29 to move together. The moving speed is consistent with the moving speed of the mounting plate 13, which ensures that the pressure between the pressure roller 36 and the cloth 28 is constant.
[0045] The driving end of motor 2 9 and screw 2 22 as well as the driving end of motor 3 10 and screw 1 16 are connected via a coupling 11; the coupling 11 has a vibration reduction effect, which can effectively reduce the impact of the vibration generated by the operation of motor 3 10 on the inflatable component, thereby further improving the stability of the inflation of the inflatable component.
[0046] The specific operating steps of this device are as follows: To fix the fabric 28, first flatten the fabric 28 and place it on the top of the two placement cylinders 32, then press the fabric 28 into the gap between the two placement cylinders 32, and then lock the fabric 28 with the locking assembly so that the fabric 28 is attached to the outer surface of the placement cylinders 32; The friction protrusion 18 is adjusted by adjusting the height of the friction protrusion 18 through the lifting assembly so that the friction protrusion 18 and the fabric 28 are pressed against each other. During the adjustment, the pressure between the fabric 28 and the friction protrusion 18 needs to be controlled. After the height adjustment of the friction protrusion 18 is completed, the friction protrusion 18 is driven to move by the driving component. The friction protrusion 18 moves and rubs against the fabric 28, thereby performing a wear resistance test. After a certain frequency of testing, the test position is changed by the transposition component to perform a multi-point test. As the driving component operates, the inflation component will be driven to operate, and air will be inflated into the placement tube 32. The tension of the fabric 28 is adjusted through the inflation component. After the tension adjustment is completed, since the driving component needs to continue to operate, the synchronization component needs to be started at this time. Under the action of the synchronization component, the tension is guaranteed to remain unchanged for friction testing. At the same time, the inflation component can also perform multi-tension adjustment to perform multi-tension testing. Multi-point testing and multi-tension testing require at least nine tests, and the test results are more accurate.
[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
