Detailed Implementation

[0023] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] Reference Figures 1-3 This application illustrates an embodiment of a ceiling fan IPX4 rain test device, comprising: a lifting mechanism 100, a sample mounting platform 200, and a quick-installation mechanism 300;

[0025] The fixed end of the lifting mechanism 100 is adapted to connect to the bearing component, and its lifting end is connected to the sample mounting platform 200 to drive the sample mounting platform 200 to perform vertical lifting motion.

[0026] The quick-installation mechanism 300 includes a first component 310 fixed to the sample installation platform 200 and a second component 320 adapted to connect to the ceiling fan mounting base; the first component 310 is provided with a plurality of elastic locking pins 311, and the second component 320 is provided with L-shaped slots 322 that correspond one-to-one with and fit the elastic locking pins 311.

[0027] The second component 320 can be detachably locked and fixed to the first component 310 by means of the L-shaped slot 322 and the elastic locking pin 311, in a push-in and rotational manner.

[0028] In the embodiments of this application, compared with the problems of difficult hoisting and low testing efficiency of the ceiling fan rain test device in the prior art, this application provides a safe and quick solution, specifically: including a lifting mechanism 100, a sample mounting platform 200, and a quick-installation mechanism 300; the fixed end of the lifting mechanism 100 is adapted to connect to the bearing component, and its lifting end is connected to the sample mounting platform 200 to drive the sample mounting platform 200 to perform vertical lifting and lowering movements; the quick-installation mechanism 300 includes a first component 310 fixed to the sample mounting platform 200, and a second component 320 adapted to connect to the ceiling fan mounting base; the first component 310 is provided with a plurality of elastic locking pins 311, and the second component 320 is provided with L-shaped slots 322 that correspond one-to-one with and fit the elastic locking pins 311; the second component 320 can be detachably locked and fixed to the first component 310 by the cooperation of the L-shaped slots 322 and the elastic locking pins 311, in a pushing and rotating manner. The vertical lifting of the sample installation platform 200 via the lifting mechanism 100 allows for safe and convenient ground-based preparation of the ceiling fan sample, including clamping, alignment, and wiring. This fundamentally eliminates the risks of working at heights and significantly improves operational safety. Simultaneously, the quick-clamping mechanism utilizes a push-in and rotation locking mechanism between the first component 310 and the second component 320, along with the engagement of the elastic locking pin 311 and the L-shaped slot 322. This enables rapid and reliable connection and separation between the ceiling fan sample and the testing device without any tools. This not only significantly improves installation efficiency and shortens test preparation time, but its mechanical self-locking feature also ensures the stability and safety of the connection during testing, thus providing a solid foundation for the accuracy and repeatability of rain testing. The overall structure of this solution is compact, and the operation is simple, effectively solving the problems of low efficiency, safety hazards, and poor test consistency in traditional testing methods.

[0029] The following will further describe an IPX4 rain test device for ceiling fans in this exemplary embodiment.

[0030] In one embodiment of this application, the fixed end of the lifting mechanism 100 is adapted to connect to a load-bearing component, which may be a load-bearing beam or bracket in a test workshop. Its lifting end is connected to the sample mounting platform 200, driving the sample mounting platform 200 to perform vertical lifting movements. That is, the lifting end of the lifting mechanism 100 faces downwards, and during operation, it drives the sample mounting platform 200 below to rise and fall, facilitating the installation of ceiling fan samples for testing. The vertical lifting of the sample mounting platform 200 via the lifting mechanism 100 allows adjustment of the ceiling fan sample height according to testing requirements, adapting to different specifications of rain test pendulums. The quick-installation mechanism 300 includes a first component 310 fixed to the sample mounting platform 200 and a second component 320 adapted to connect to the ceiling fan mounting base. The first component 310 is provided with multiple elastic locking pins 311, and the second component 320 has L-shaped slots 322 that correspond one-to-one with and fit the elastic locking pins 311. The second component 320 can be detachably locked to the first component 310 by engaging the elastic locking pins 311 through the L-shaped slots 322, in a push-in and rotational manner. The quick-installation mechanism 300 adopts a push-in and rotational engagement structure of elastic locking pins 311 and L-shaped slots 322, replacing the traditional bolt fixing method. This reduces the assembly and disassembly time of the ceiling fan sample from the traditional 10-15 minutes to 1-2 minutes, significantly improving testing efficiency. Simultaneously, the detachable locking method balances connection stability and ease of operation, ensuring that the ceiling fan sample does not shift during testing.

[0031] As an example, the lifting mechanism 100 can be one of an electric push rod, a lead screw and nut mechanism, or a scissor lift platform; all three are existing and mature lifting actuators. Figure 1 As shown in the figure, this embodiment takes a scissor lift platform as an example. The scissor lift platform has the advantages of large lifting stroke and good platform stability, and can adapt to testing needs of different heights.

[0032] As an example, the effective lifting stroke of the lifting mechanism 100 is 1-1.5m. The effective lifting stroke of 1-1.5m covers the testing requirements of existing mainstream ceiling fans (diameter 0.9-1.8m), ensuring that the center of the ceiling fan sample is at the same horizontal height as the center of the rain test tube (usually the center height of the tube is 2-2.5m); the stroke design also takes into account the ease of operation, allowing operators to easily install the ceiling fan sample at the lowest position, and adapting to testing scenarios with large tubes at the highest position.

[0033] Furthermore, the lifting speed of the lifting mechanism 100 within its stroke range can be stably controlled at 50-100 mm / s to avoid excessive speed causing sample shaking.

[0034] Furthermore, guide rods 110 are symmetrically arranged on both sides of the lifting mechanism 100; the top end of the guide rod 110 is fixed to the bearing member through a connecting seat; a guide groove is formed on the guide rod 110 along its axial direction; the sample mounting platform 200 or the movable part of the lifting mechanism 100 slides in cooperation with the guide groove through a slider. The symmetrical guide rods 110 on both sides form a stable guiding structure. With the sliding cooperation of the guide groove and the slider, the radial sway during the lifting process can be controlled within ±1mm, improving the stability of the sample mounting platform 200; the design of the guide groove can prevent the slider from deflecting during the sliding process, ensuring the verticality of the lifting direction; the connecting seat is fixed to the bearing member with bolts, which improves the installation stability of the guide rod 110 and avoids loosening after long-term use.

[0035] It should be noted that the slider is set according to the specific structure of the lifting mechanism 100. For example, when the lifting mechanism 100 is a scissor lift platform, the slider can be set outside its multiple cross hinge points, so as not to affect its folding and lifting, and to provide guidance.

[0036] In one embodiment of this application, both the first component 310 and the second component 320 are plate-shaped structures, featuring lightweight and standardized characteristics, facilitating processing, manufacturing, and installation positioning. The second component 320 has a vertically extending upright plate 321 along its edge, providing a stable mounting carrier for the L-shaped slot 322, while also increasing the contact area with the first component 310, thus improving connection stability. The elastic locking pin 311 is disposed on the side of the first component 310; the L-shaped slot 322 is formed on the upright plate 321, including a vertically connected guide section and a transverse locking section. The vertical guide section penetrates the edge of the upright plate 321 to allow the elastic locking pin 311 to be guided in and at least partially penetrates the upright plate 321, enabling quick insertion of the elastic locking pin 311 and reducing operational difficulty; the transverse locking section is a blind groove structure, which can axially limit the elastic locking pin 311, preventing disengagement during rotation and further improving locking reliability. Furthermore, the vertical guide section penetrates at least partially through the upright plate 321, while the horizontal locking section is a blind groove structure, that is, it does not penetrate the upright plate 321, so that the elastic locking pin 311, which is initially in an elongated state, is inserted from the vertical guide section, and when it is rotated and slid into the horizontal locking section, it retracts and abuts against the horizontal locking section to lock it.

[0037] In one embodiment of this application, the quick-release mechanism 300 further includes a safety locking component, which includes at least one mechanical safety lever 330. The mechanical safety lever 330 is movably disposed on the first component 310 or the sample mounting platform 200. The mechanical safety lever 330 can be adapted to engage with the vertical guide section of the L-shaped slot 322. When the second component 320 rotates to the locking position, the mechanical safety lever 330 is moved so that part of its structure extends into the vertical guide section of either L-shaped slot 322 to prevent the second component 320 from rotating in the opposite direction. Adding a mechanical safety lever 330 to the basic quick-release mechanism 300 forms a double locking mechanism, preventing the second component 320 from loosening due to reverse rotation caused by vibration, accidental collisions, or other factors during testing, thus improving the safety redundancy of the device. The mechanical safety lever 330 is simple to operate; simply moving it locks or unlocks the device without affecting the overall disassembly and assembly efficiency. One or two mechanical safety levers 330 can be set as needed to further improve locking reliability.

[0038] It should be noted that the movable connections of the mechanical safety lever 330, such as the pivot connection and the elastic reset, are existing technologies and will not be described in detail.

[0039] In one embodiment of this application, the device further includes an infrared alignment unit, which includes an infrared laser instrument mounted on the sample mounting platform 200 and an alignment target mounted on the test station floor or the swing tube support. The center of the alignment target corresponds to the center of the rain test swing tube. By aligning the laser beam emitted by the infrared laser instrument with the center of the alignment target, it is possible to quickly determine whether the center of the ceiling fan sample coincides with the center of the rain test swing tube. The alignment accuracy error can be controlled within ±2mm, solving the problem of low accuracy caused by reliance on manual visual judgment in traditional devices. The alignment target and the center of the swing tube are fixedly aligned, eliminating the need for recalibration for each test and further improving operational efficiency. The infrared alignment unit is unaffected by ambient light and can still work stably under complex lighting conditions in the test workshop.

[0040] It should be noted that when setting up an infrared laser, if a structure obstructs it, a through hole can be made in the structure to allow infrared rays to pass through. For example, when the infrared laser is set up on the sample mounting platform 200, through holes can be made at corresponding positions of the plate-shaped first component 310 and the second component 320 to avoid obstruction.

[0041] In one embodiment of this application, a waterproof box 210 is provided on the top of the sample mounting platform 200. A waterproof power strip is installed inside the waterproof box 210 to provide test power for the ceiling fan sample. The waterproof box 210 adopts an IPX5 waterproof design, which can effectively prevent splashing rainwater from entering during the test. The waterproof power strip uses a waterproof socket conforming to the GB / T 1002-2021 standard to ensure electrical safety during the power supply process.

[0042] As an example, the waterproof box 210 is set on top of the sample mounting platform 200, close to the power supply interface of the ceiling fan sample, which shortens the length of the power supply cable and avoids the cable mess affecting the test operation.

[0043] Furthermore, the waterproof box 210 is equipped with a removable sealing cover for easy inspection and replacement of the waterproof power strip.

[0044] In one embodiment of this application, the device further includes a control module, which is communicatively connected to the lifting mechanism 100 and the infrared laser, and is used to receive alignment signals and control the lifting operation of the lifting mechanism 100. The control module can receive alignment signals from the infrared laser (such as the level signal output during laser alignment) and automatically control the start and stop of the lifting mechanism 100, thereby automating the alignment process and reducing manual intervention.

[0045] As an example, the control module can be equipped with a touch screen that can display information such as lifting height, centering status, and locking status in real time, making it easy for operators to monitor; it can support manual / automatic switching to improve the operational flexibility of the device; and it can have overload protection function, automatically stopping the machine when the lifting mechanism exceeds the rated value to avoid equipment damage.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.
