Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproof testing, specifically a power-on device for products used in waterproof and dustproof testing. Background Technology
[0002] In IP dust and water resistance tests, such as IPX3, IPX4, IPX4K, and IPX9K, the sample needs to be rotated at a specified speed during the test. However, powering on the sample at this time becomes very difficult. During IPX3, IPX4, and IPX4K tests, the sample is rotated at 1 to 3 revolutions per minute (RPM), while in IPX9K tests, the sample is rotated at 5 ± 1 RPM. Due to the different speeds, different lengths of wire harnesses are required for the tests. Currently, the 1 to 3 RPM solution uses a 5-meter wire harness, while the 5 ± 1 RPM solution uses a 10 to 15-meter wire harness. The harness is pre-wound in the opposite direction of rotation before powering on to begin the test. This setup is time-consuming and inefficient. Novice testers may encounter knots due to improper winding, requiring test interruption. Furthermore, if the sample wire harness is too thick or stiff, it cannot be wound properly, failing to meet the power-on requirements. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figures 1 to 3 As shown, a power-on device for a product in a waterproof and dustproof test according to this embodiment includes:
[0027] The fixed module 1 has a circular conductive wave groove 11 on its upper surface that radiates outward from its center. The conductive wave groove 11 is used to limit the first conductive module 13 so that the first conductive module 13 moves within the conductive wave groove 11 during the rotation of the device rotating shaft 2 relative to the fixed module 1.
[0028] The device rotating shaft 2 passes through the center of the fixed module 1 and extends in a direction perpendicular to the upper surface of the fixed module 1. This ensures that the center of the conductive corrugated groove 11 is the same as the center of the device rotating shaft 2, and consequently, that each groove in the conductive corrugated groove 11 is equidistant from the device rotating shaft 2 at different positions. The device rotating shaft 2 can rotate relative to the fixed module 1 along its axial direction, thereby causing the upper sliding module 3 and the second conductive module 31 to rotate relative to the fixed module 1 during rotation.
[0029] The upper sliding module 3 is sleeved outside the rotating shaft 2 of the device and covers the upper surface of the fixed module 1, so that the conductive wave groove 11 is isolated from the outside world during the test, thereby enabling the upper sliding module 3 to protect the conductive wave groove 11. During the rotation of the upper sliding module 3 with the rotating shaft 2 of the device, the upper sliding module 3 can rotate relative to the fixed module 1.
[0030] The rotating shaft upper support plate 4 is connected to the upper end of the rotating shaft 2 of the device. The rotating shaft upper support plate 4 is provided with the sample to be tested 5, so that the rotating shaft upper support plate 4 can drive the sample to be tested 5 to rotate together with the rotating shaft 2 relative to the fixed module 1.
[0031] A first conductive module 13 is disposed on the fixed module 1 and communicates with the conductive wave groove 11, thereby allowing the first conductive module 13 to maintain a fixed position with the fixed module 1. The first conductive module 13 is also used to connect to an external control system such as a power supply.
[0032] The second conductive module 31 is disposed on the upper sliding module 3 and communicates with the conductive corrugated groove 11. The second conductive module 31 is electrically connected to the sample 5 to be tested, so that during the rotation of the upper sliding module 3 relative to the fixed module 1, the second conductive module 31 can always remain within the conductive corrugated groove 11 and communicate with different positions of the conductive corrugated groove 11 during rotation. Preferably, both the first conductive module 13 and the second conductive module 31 are externally insulated, so that they can provide good protection for the internal structure during waterproof testing. The second conductive module 31 can be electrically connected to a short-circuit test module, which can identify water ingress short circuits and protect the entire structure.
[0033] In this embodiment, during the testing of the sample 5, the sample 5 is first fixedly mounted on the upper support plate 4 of the rotating shaft. Then, the rotating shaft 2 of the device is rotated. The rotating shaft 2 of the device synchronously drives the upper sliding module 3 and the upper support plate 4 of the rotating shaft to rotate relative to the fixed module 1. During this process, the second conductive module 31 rotates with the sample 5 and is always located in the conductive wave groove 11 during the rotation. The first conductive module 13 remains relatively stationary with the fixed module 1. The first conductive module 13 transmits electrical signals to the second conductive module 31 through the conductive wave groove 11. The first conductive module 13 is controlled and recorded by an external control system such as a power supply.
[0034] The above structure effectively solves the problem of sample powering on during rotation in IP dustproof and waterproof testing. The slide rail speed is adjusted according to the rotation speed of the sample 5 under test, so that the wire harness has only a small pulling force, which does not affect the overall structure and does not cause stress deformation. In waterproof testing of different specifications and speeds, the wire harness connecting the sample 5 under test and the second conductive module 31 does not need to exceed 2m, saving costs and improving compatibility with different tests.
[0035] Specifically, it also includes copper strips 6, which are located in the conductive wave groove 11. The upper end of the copper strip 6 is fixedly connected to the second conductive module 31, and the lower end of the copper strip 6 is slidably connected to the conductive wave groove 11. Thus, during the rotation of the device's rotating shaft 2, the copper strip 6 rotates with the second conductive module 31 at different positions within the conductive wave groove 11, achieving a conductive effect between the second conductive module 31 and the conductive wave groove 11. Through the above structure, a multi-channel energized and rotatable effect is achieved between the second conductive module 31 and the conductive wave groove 11. The arrangement of multiple copper strips 6 can also ensure the stability of data transmission.
[0036] Specifically, it also includes a spring element 7, which is disposed on the support plate 4 on the rotating shaft and sleeved on the outside of the copper strip 6. This allows the spring element 7 to act as a buffer during the movement of the second conductive module 31 relative to the conductive wave groove 11, thereby protecting the second conductive module 31, the copper strip 6, and the conductive wave groove 11. Through the above structure, a multi-channel, high-current-capable, high- and low-speed stable rotation with copper strip 6 and spring structure sliding is achieved.
[0037] Specifically, the second conductive module 31 is connected to the sample 5 under test via a waterproof wire harness. One end of the waterproof wire harness is connected to the side of the sample 5 under test, and the other end is connected to the upper end of the second conductive module 31. This structure eliminates the need for pre-winding the wire, reducing the time required for wire harness winding and improving efficiency. Furthermore, it avoids the possibility of tangles caused by improper winding by beginners, which could lead to test interruptions. It also prevents the wire harness from being too thick or stiff, which would prevent winding and thus fail to meet the power-on requirements.
[0038] Specifically, the lower surface of the fixing module 1 is provided with a plurality of fixing threaded grooves 12, so that the fixing module 1 is fixedly connected to the fixing platform and other structures through the fixing threaded grooves 12, thereby making the fixing module 1 more stable during the rotation of the equipment rotating shaft 2 relative to the fixing module 1.
[0039] Specifically, it includes an adjustable planetary bearing 8 disposed between the fixed module 1 and the equipment rotating shaft 2. The inner ring wall of the adjustable planetary bearing 8 is sleeved on the outside of the equipment rotating shaft 2, and the outer ring wall of the adjustable planetary bearing 8 is disposed on the inner wall of the fixed module 1. This ensures a high relative rotation effect during the relative rotation of the fixed module 1 and the equipment rotating shaft 2, avoiding interference.
[0040] Specifically, it also includes a sealing ring 9, which has a first contact member that abuts against the fixed module 1, a second contact member that abuts against the inner wall surface of the rotating shaft support plate 4 located on the outer periphery of the fixed module 1, and a connecting member that connects the first contact member and the second contact member. The contact area between the first contact member and the fixed module 1 is smaller than the contact area between the second contact member and the rotating shaft support plate 4, so that during the rotation of the device rotating shaft 2 relative to the fixed module 1, the sealing ring 9 can rotate with the rotating shaft support plate 4 relative to the fixed module 1, and during this process, the sealing ring 9 can maintain the sealing effect between the fixed module 1 and the rotating shaft support plate 4.
[0041] Specifically, a lubricant is provided between the first contact member and the fixing module 1, so that the relative rotation between the sealing ring 9 and the fixing module 1 can be smoother under the action of the lubricant.
[0042] This utility model uses specific embodiments to illustrate the principle and implementation of the utility model. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of the utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of the utility model. Therefore, the content of this specification should not be construed as a limitation of the utility model.
