Description

Technical Field

[0001] The present invention relates to the technical field of buffer support testing, in particular to a hinge buffer support testing device and a testing method for the device. Background Art

[0002] The structure of the existing hinge generally includes a base installed on the door body, a fixed base installed on the frame, and a transmission component hinged between the base and the fixed base. The transmission component allows the base to open and close on the fixed base, thereby realizing the opening and closing of the door body on the frame.

[0003] In order to improve the user experience and reduce the noise caused by impact, a buffer damper is added to the hinge.

[0004] When the user closes the door, the hinge installed on the door panel will gradually close along with the door panel. When the door is closed to a certain angle, the buffering function of the hinge will reduce the closing speed, so that the door panel will not hit the cabinet violently when it contacts the cabinet, so as to better improve the user experience. At the same time, the closing speed is mainly determined by the user's closing force. Theoretically, without considering other factors, the greater the closing force, the greater the speed (i.e. kinetic energy) obtained by the door panel. In order to prevent the door panel from directly hitting the cabinet, the required hinge buffering support force is greater. However, if the limit idea is applied, if the sudden change value of the buffering support force is large, the instantaneous change rate of the buffering damper's buffering force needs to match the corresponding buffering support force to prevent insufficient door closing smoothness or slow closing speed. Therefore, it is necessary to test the buffering support force of the buffering hinge. Summary of the Invention

[0009] The buffer detection component includes a buffer bearing plate, a buffer pad, and a door buffer detection piece. The buffer bearing plate is installed at the bottom of the test frame.

[0045] The present invention will be further described below in conjunction with the accompanying drawings.

[0046] According to the attached Figures 1 to 13 As shown, the hinge buffer support test equipment of the present invention includes a test door 1, a test buffer hinge 2, a test frame 3, and a test device. The test buffer hinge 2 is hinged on the test door 1 and the test frame 3 respectively, and the test device includes a load-bearing detection component 4, an angle detection component 5, and a buffer detection component 6.

[0047] Among them, the load-bearing detection component 4 includes a load-bearing detection support frame 41, a weight 42 and a height-adjustable sliding connection. The load-bearing detection support frame 41 is installed on the test frame 3, and the sliding connection is connected to the load-bearing detection support frame 41 by sliding up and down, and one end of the sliding connection is connected to the test door 1, and the other end of the sliding connection is connected to the weight 42. In addition, the angle detection component 5 includes an angle detection mounting plate 51 and an angle adjustment swing member. The angle detection mounting plate 51 is installed on the test frame 3, and one swing end of the angle adjustment swing member is connected to the angle detection mounting plate 51 by sliding left and right, and the other swing end of the angle adjustment swing member is movably connected to the test door 1.

[0048] Furthermore, the buffer detection component 6 includes a buffer bearing plate 61, a buffer pad 62, and a door buffer detection component. The buffer bearing plate 61 is installed at the bottom of the test frame 3, the buffer pad 62 is arranged on the buffer bearing plate 61 corresponding to the weight 42, and the door buffer detection component is installed on one side of the test frame 3.

[0049] The load-bearing detection component 4 and the buffer detection component 6 are coordinated, and the structure is simple. By adjusting the height of the sliding connection and the load-bearing detection support frame 41, the initial height of the weight 42 relative to the buffer pad 62 can be adjusted. By increasing or decreasing the weight 42 and adjusting the initial height of the weight 42 relative to the buffer pad 62, impact tests of different sizes can be performed.

[0050] By using the angle detection component 5 and adjusting the relative position of the angle adjustment swing member with respect to the angle detection mounting plate 51 , the initial angle of the test door 1 with respect to the test frame 3 can be adjusted to set different test environments.

[0051] Reference Figures 1 to 13 As shown, in further detail, the sliding connection includes a connecting steel wire 43 and a detection sliding wheel 44. The detection sliding wheel 44 can be rotatably connected to the load-bearing detection support frame 41. The connecting steel wire 43 is slidingly connected to the detection sliding wheel 44, and one end of the connecting steel wire 43 is fixedly connected to the test door 1, and the other end of the connecting steel wire 43 is connected to the weight 42.

[0052] Moreover, the load-bearing detection support frame 41 is provided with a load-bearing detection adjustment hole 45 for adjusting the upper and lower installation positions of the detection sliding wheel 44 , and the detection sliding wheel 44 slides up and down on the load-bearing detection adjustment hole 45 via a rotating shaft.

[0053] During this process, the door buffer detection member includes a buffer seat 63 and a buffer block 64. The buffer seat 63 is installed on one side of the test frame 3, and the buffer block 64 is installed on the buffer seat 63. The test door 1 collides with the buffer block 64 when closing.

[0054] To facilitate adjustment, this device uses a fixed length of connecting wire 43. By adjusting the position of detection sliding wheel 44 within load-bearing detection adjustment hole 45, the height of detection sliding wheel 44 relative to load-bearing detection support frame 41 is adjusted, thereby adjusting the initial height of weight 42 relative to cushion 62. Thus, by adding or removing weight 42 and adjusting its initial height relative to cushion 62, impact tests of varying magnitudes can be performed. This simple structure facilitates testing operations, ease of use, and reduced costs.

[0055] Reference Figures 1 to 13 As shown in the figure, the angle adjustment swing member includes an angle swing rod 52 and an angle connecting wheel 53. One swing end of the angle swing rod 52 is slidably connected to the angle detection mounting plate 51, and the angle connecting wheel 53 is rotationally connected to the other swing end of the angle swing rod 52. The test door 1 can roll in contact with the angle connecting wheel 53 as it closes.

[0056] Among them, the angle detection mounting plate 51 has upper and lower detection adjustment slots 54, and one swing end of the angle swing rod 52 is installed with front and rear adjustment shafts arranged in sequence from the outside to the inside, and the front and rear adjustment shafts can be slidably connected to the upper and lower detection adjustment slots 54.

[0057] By adjusting the position of the front-to-rear adjustment axis of the angle swing lever 52 relative to the upper and lower detection adjustment slots 54, and thereby adjusting the position of the stop plate relative to the angle detection mounting plate 51, the angle of the angle connecting wheel 53 relative to the test frame 3 can be adjusted, thereby adjusting the initial angle of the test door 1 relative to the test frame 3. This allows for different test environments and facilitates analysis of hinge performance under varying test parameters.

[0058] In addition, the test frame 3 of the present structure is made of aluminum alloy profiles, which is light in weight and is easy to use and maintain.

[0059] Reference Figures 1 to 13As shown, in further detail, the test door 1 is provided with a six-axis attitude sensor 7 for the angular velocity of the test door 1 , the six-axis attitude sensor 7 can be detached and assembled on one side of the test door 1 , and the signal of the six-axis attitude sensor 7 is connected to the host computer 8 .

[0060] In conjunction with the six-axis attitude sensor 7, the angular velocity of the test door 1 can be measured, and it can be connected to the host computer 8 through a TTL to USB data transmission line. The speed data can be measured in real time and the data can be exported locally, which can provide a certain data source for scientific researchers to conduct analysis and research.

[0061] Reference Figures 1 to 13 As shown, a testing method includes testing a buffer hinge 2, wherein the specific testing steps of the buffer support force of the test buffer hinge 2 using the hinge buffer support testing device are as follows:

[0062] Step 1: The test buffer hinge 2 is pre-treated under temperature and humidity conditions of T1, and the test should be carried out under indoor temperature conditions of T2;

[0063] Step 2: Set the position where one end of the connecting steel wire 43 is connected to the test door 1 as point A, and adjust the installation height of the detection sliding wheel 44 on the load-bearing detection support frame 41 so that the weight 42 is at a height h1 directly above the buffer pad 62;

[0064] Step 3: Adjust the left and right movement position of the angle swing rod 52 relative to the angle detection mounting plate 51 to adjust the angle of the angle connecting wheel 53 relative to the test frame 3, thereby defining the initial angle of the test door 1 as θ1, so that the test door 1 is in the first position, and hang a weight 42 on the other end of the connecting steel wire 43, and set the weight of the weight 42 to m1. When the weight 42 gradually falls until it lands on the buffer pad 62, the test door should be in the second position, and the angle between the test door 1 and the test frame 3 is θ2;

[0065] Step 4: Keep the weight 42 still and suspended, and ensure that the weight 42 does not shake before starting the test;

[0066] Step 5: Test door 1 with free release and conduct 10 tests;

[0067] Step 6: Set the test door 1 as "qualified" if it does not directly collide with the test frame after the weight 42 contacts the buffer pad 62, and "unqualified" if it directly collides with the test frame. If all 10 buffer support tests are qualified, the six-axis attitude sensor 7 will feed back the corresponding information to the host computer 8 in real time, and it will be determined as qualified. If there is one unqualified test in 10 tests, the six-axis attitude sensor 7 will feed back the corresponding information to the host computer 8 in real time, and it will be determined as unqualified.

[0068] In actual application, the test buffer hinge 2 has components made of hygroscopic plastic (such as polyamide), so the temperature of the temperature and humidity T2 is set at 23±5° C., the humidity is set at (50±5)%, and the pretreatment is performed for 7 days.

[0069] The point A is located at the center of the height direction of the test door 1 and is 100 mm away from the edge of the test door 1 in the width direction of the test door 1. The height h1 of the weight 42 directly above the buffer pad 62 is set to 200 mm;

[0070] The initial angle θ1 of the test door 1 is defined as 85° to 95°, and the included angle θ2 between the test door 1 and the test frame 3 is set to 45°.

[0071] Furthermore, the weight m1 of the weight 42 is set to 2.4 kg.

[0072] Through the normalization principle, the closing force is converged to a fixed value of 2.4kg, and this fixed value of 2.4kg is used as the company's hinge buffer support test standard. In addition, an evaluation standard is established for the buffer support test method, setting the test door 1 as "qualified" if it is cushioned after the weight 42 falls on the buffer pad 62 and does not directly collide with the test frame 3. If all 10 buffer support tests are qualified, the six-axis attitude sensor 7 will feed back the corresponding information to the host computer 8 in real time, and determine it as qualified. If one of the 10 tests fails, the six-axis attitude sensor 7 will feed back the corresponding information to the host computer 8 in real time, and determine it as unqualified. The test is convenient to operate, simple to use, widely applicable, and accurate in determination, which is beneficial for companies to screen and analyze hinge performance.

[0073] The above specific embodiments are only specific implementation methods with better effects of the present invention. Any structure that is the same or equivalent to the hinge buffer support testing device of the present invention is within the protection scope of the present invention.
