Description

Technical Field

[0001] This utility model relates to the technical field of buffer support testing, specifically a hinge buffer support testing device. Background Technology

[0002] The structure of existing hinges generally includes a base installed on the door, a fixed seat installed on the frame, and a transmission component hinged between the base and the fixed seat. The transmission component enables the base to open and close on the fixed seat, thereby enabling the door to open and close on the frame.

[0003] To improve the user experience and reduce noise from impacts, a buffer damper is added to the hinge.

[0004] When a user closes the door, the hinges mounted on the door panel gradually close along with the panel. When the door reaches a certain angle, the hinges' cushioning function reduces the closing speed, preventing a violent impact when the door panel contacts the cabinet, thus improving the user experience. The closing speed is primarily determined by the user's closing force. Theoretically, without considering other factors, the greater the closing force, the greater the velocity (i.e., kinetic energy) the door panel gains. To prevent the door panel from directly impacting the cabinet, a greater hinge cushioning force is required. However, applying the concept of limits, if the sudden change in the cushioning force is large, the instantaneous rate of change of the damper's cushioning force must match the corresponding cushioning force to prevent insufficient closing smoothness or a very slow closing speed. Therefore, testing the cushioning force of the soft-close hinge is necessary. Utility Model Content

[0033] The present invention will now be further described with reference to the accompanying drawings.

[0034] According to the appendix Figures 1 to 13 As shown, the hinge buffer support testing device of this utility model 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 to the test door 1 and the test frame 3 respectively. The test device includes a load-bearing detection component 4, an angle detection component 5, and a buffer detection component 6.

[0035] The load-bearing detection component 4 includes a load-bearing detection support frame 41, a weight 42, and a height-adjustable sliding connector. The load-bearing detection support frame 41 is mounted on the test frame 3. The sliding connector is slidably connected vertically to the load-bearing detection support frame 41, with one end connected to the test door 1 and the other end connected to the weight 42. The angle detection component 5 includes an angle detection mounting plate 51 and an angle-adjusting swing member. The angle detection mounting plate 51 is mounted on the test frame 3. One swinging end of the angle-adjusting swing member is slidably connected left and right to the angle detection mounting plate 51, and the other swinging end is movably connected to the test door 1.

[0036] Furthermore, the buffer detection component 6 includes a buffer support plate 61, a buffer pad 62, and a door buffer detection component. The buffer support plate 61 is installed at the bottom of the test frame 3, the buffer pad 62 is disposed on the buffer support plate 61 corresponding to the weight 42, and the door buffer detection component is installed on one side of the test frame 3.

[0037] The structure is simple, using the load-bearing detection component 4 and the buffer detection component 6 in combination. By adjusting the height of the sliding connector 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 magnitudes can be performed.

[0038] By using the angle detection component 5 and adjusting the relative position of the angle adjustment swing component with respect to the angle detection mounting plate 51, the initial angle of the test gate 1 relative to the test frame 3 can be adjusted to set different test environments.

[0039] Reference Figures 1 to 13 As shown, in further detail, the sliding connector includes a connecting steel wire 43 and a detection sliding wheel 44. The detection sliding wheel 44 is rotatably connected to the load-bearing detection support frame 41. The connecting steel wire 43 is slidably connected to the detection sliding wheel 44, and one end of the connecting steel wire 43 is fixedly connected to the test door 1. The other end of the connecting steel wire 43 is connected to a weight 42.

[0040] Furthermore, the load-bearing detection support frame 41 has 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.

[0041] During this process, the door buffer detection component 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 closes and comes into contact with the buffer block 64.

[0042] In this structure and device, for ease of adjustment, the connecting steel wire 43 is set to a fixed length. By adjusting the position of the detection sliding wheel 44 relative to the load-bearing detection adjustment hole 45, the height of the detection sliding wheel 44 relative to the load-bearing detection support frame 41 can be adjusted, thereby adjusting the initial height of the weight 42 relative to the buffer pad 62. In this way, 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 magnitudes can be performed. The structure is simple, the testing operation is convenient, it is easy to use, and reduces costs.

[0043] Reference Figures 1 to 13 As shown in the diagram, further detailed, the angle adjusting swing component 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 rotatably connected to the other swing end of the angle swing rod 52. The test door 1 can roll into contact with the angle connecting wheel 53 as it closes.

[0044] The angle detection mounting plate 51 has an upper and lower detection adjustment groove 54, and one swing end of the angle swing rod 52 is equipped with a front and rear adjustment shaft arranged sequentially from the outside to the inside. The front and rear adjustment shafts can be slidably connected to the upper and lower detection adjustment groove 54.

[0045] By adjusting the position of the front and rear adjustment shaft of the angle swing rod 52 relative to the upper and lower detection adjustment groove 54, the position of the limiting plate relative to the angle detection mounting plate 51 can be adjusted, thereby adjusting the angle connecting wheel 53 relative to the test frame 3, and thus adjusting the initial angle of the test door 1 relative to the test frame 3. In this way, by adjusting the initial angle of the test door 1 relative to the test frame 3, different test environments can be conducted, which is beneficial for analyzing the hinge performance under different test parameters.

[0046] In addition, the test frame 3 of this structure is made of aluminum alloy profile, which is lightweight and facilitates use and maintenance.

[0047] Reference Figures 1 to 13As shown, in further detail, the test gate 1 is equipped with a six-axis attitude sensor 7 for measuring the angular velocity of the test gate 1. The six-axis attitude sensor 7 can be detached and installed on one side of the test gate 1, and the six-axis attitude sensor 7 is connected to a host computer 8.

[0048] With the six-axis attitude sensor 7, the angular velocity of the test gate 1 can be measured, and it can be connected to the host computer 8 via a TTL to USB data cable. The velocity data can be measured in real time and exported to the local computer, providing a certain data source for researchers to conduct analysis and research.

[0049] Reference Figures 1 to 13 As shown, a test method includes a test buffer hinge 2. The specific testing steps for the buffer support force of the test buffer hinge 2 using the hinge buffer support testing equipment are as follows:

[0050] Step 1: The test buffer hinge 2 is pretreated under temperature and humidity conditions T1, and the test should be carried out under indoor temperature conditions T2;

[0051] Step 2: Set one end of the connecting steel wire 43 to point A at the test door 1, 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;

[0052] 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. The other end of the connecting steel wire 43 is suspended by a weight 42, and the weight of the weight 42 is set 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. At this time, the angle between the test door 1 and the test frame 3 is θ2.

[0053] Step 4: Keep weight 42 stationary and ensure it does not shake before starting the test;

[0054] Step 5: Free release test gate 1 and conduct 10 tests;

[0055] Step 6: Set the test gate 1 to "pass" if it does not directly impact the test frame after the weight 42 contacts the buffer pad 62, and "fail" if it directly impacts the test frame. If all 10 buffer support tests are passed, the six-axis attitude sensor 7 will feed back the corresponding information to the host computer 8 in real time and determine that it is passable. If one of the 10 tests is failed, the six-axis attitude sensor 7 will feed back the corresponding information to the host computer 8 in real time and determine that it is failable.

[0056] In practical applications, the test buffer hinge 2 has a component made of hygroscopic plastic (such as polyamide), and the temperature of the temperature and humidity T2 is set at 23±5℃, the humidity is set at (50±5)%, and the pretreatment is carried out for 7 days.

[0057] Point A is located at the center of the height of the test gate 1 and 100mm from the edge of the test gate 1 in the width direction. The height h1 of the weight 42 directly above the buffer pad 62 is set to 200mm.

[0058] The initial angle θ1 of the test gate 1 is set to 85° to 95°, and the included angle θ2 between the test gate 1 and the test frame 3 is set to 45°.

[0059] Furthermore, the weight m1 of the weight 42 is set to 2.4 kg.

[0060] By applying normalization principles, a fixed closing force of 2.4 kg is established and used as the standard for hinge cushioning support testing. Furthermore, an evaluation standard is developed for the cushioning support test method, defining "qualified" as the door 1 providing cushioning after the weight 42 falls onto the cushioning pad 62 without directly impacting the test frame 3. If all 10 cushioning support tests are qualified, the six-axis attitude sensor 7 feeds back the corresponding information to the host computer 8 in real time, determining it as qualified. If any of the 10 tests fail, the six-axis attitude sensor 7 feeds back the corresponding information to the host computer 8 in real time, determining it as unqualified. The test operation is convenient, simple to use, widely applicable, and provides accurate judgment, which is beneficial for enterprises to screen and analyze hinge performance.

[0061] The above specific embodiments are only specific implementations of the present utility model with better effects. All structures that are the same as or equivalent to the hinge buffer support testing equipment of the present utility model are within the protection scope of the present utility model.
