Description

Technical Field

[0001] This utility model relates to the field of clothes drying racks, specifically to a power unit testing device for an electric clothes drying rack. Background Technology

[0002] Electric clothes drying racks primarily use a lifting mechanism within the main unit to control the raising and lowering of the clothesline. Conventional clotheslines are installed by suspending them from the ceiling, allowing for vertical movement. Since the raising and lowering of the clothesline is controlled by the main unit, the main unit is usually also suspended from the ceiling for better control. Therefore, the performance and stability of the main unit directly affect the lifespan of the electric clothes drying rack and the user experience.

[0003] In practical operation, because the power unit is suspended from the ceiling, it is affected by the weight of the load on the clothesline, as well as its own weight. The amount of clothing on the clothesline also affects the load. Therefore, when the load on the clothesline changes, the pulling force exerted by the clothesline on the power unit also changes.

[0004] Currently, the test method for assessing the impact of the pulling force of a clothes drying rack on the power unit typically involves placing the traction mechanism and the power unit on a test platform. The power unit is then connected to the traction device, and the traction device is used to pull the power unit. However, due to the support provided by the test platform, it is impossible to simulate the gravitational force experienced by the power unit when it is suspended from the ceiling during actual operation, resulting in significant errors in the actual test results of the power unit. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a power unit testing device for an electric clothes drying rack.

[0006] The objective of this utility model is achieved through the following solution:

[0007] A power unit testing device for an electric clothes drying rack includes: a test frame, two rotary drive components, and two traction components; the test frame includes a mounting base, a support part, and two support rods, the support part being vertically mounted on the mounting base, and the two support rods being of equal height and parallel to each other on the same side of the support part, with an installation space between the two support rods; the two rotary drive components are mounted on the mounting base, with one rotary drive component located below each support rod; one end of each traction component is connected to the output end of the rotary drive component, and the other end of each traction component is in a free state and is pulled to a support rod corresponding to the top of the rotary drive component.

[0008] In one embodiment, each rotary drive includes a drive motor mounted on a mounting base, and a traction component is connected to the output shaft of the drive motor.

[0009] In one embodiment, the traction assembly includes a bracket, a reel, and a traction rope. The bracket is mounted on a mounting base, and both ends of the reel are rotatably mounted on the bracket. One end of the traction rope is wound around the reel, and the other end of the traction rope is in a free state and pulled to a support rod. One end of the reel is also connected to the output end of a rotary drive component.

[0010] In one embodiment, each support rod is also provided with a pulley, and the other end of each traction component in the free state is pulled to the corresponding pulley.

[0012] In one embodiment, each rotary drive component further includes a control unit, a first measuring unit, and a second measuring unit. The control unit is electrically connected to the drive motor, the first measuring unit, and the second measuring unit, respectively. One end of the first measuring unit is electrically connected to the drive motor, and the second measuring unit is disposed on the output shaft of the drive motor.

[0028] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings:

[0029] This utility model provides a power unit testing device for an electric clothes drying rack, such as... Figure 1 As shown, the test setup includes: a test frame 1, two rotary drive components 2, and two traction components 3. The test frame 1 is used to mount the two rotary drive components 2 and the two traction components 3. Each rotary drive component 2 is connected to one of the two traction components 3. One rotary drive component 2 drives one traction component 3, causing the two traction components 3 to generate a pulling force on the power unit 4, thus simulating the actual working scenario of the power unit 4. The performance of the power unit 4 is tested by using the pulling force generated by the traction components 3 on the power unit 4 through the rotary drive components 2 driving the traction components 3.

[0030] Specifically, such as Figure 1 As shown, the test frame 1 includes a mounting base 11, a support part 12, and two support rods 13. The support part 12 is vertically mounted on the mounting base 11. The two support rods 13 are at the same height and parallel to each other on the same side of the support part 12, and there is an installation space between the two support rods 13. Two rotary drive components 2 are mounted on the mounting base 11, and a rotary drive component 2 is located below each support rod 13. One end of each traction component 3 is connected to the output end of the rotary drive component 2, and the other end of each traction component 3 is in a free state and is pulled to a support rod 13 corresponding to the top of the rotary drive component 2.

[0031] The support part 12 provides vertical support for the two support rods 13. There is a gap between the two support rods 13 to form an installation space. When testing the power host 4, the two traction components 3 are connected to opposite ends of the power host 4 at their free ends. Then, the two rotary drive members 2 drive the two traction components 3 to rotate. After rotating, the two rotary drive members 2 output power to the two traction components 3. The two traction components 3 generate opposite traction forces on the power host 4 to pull the power host 4, so as to simulate the load borne by the power host 4 in actual work. Finally, the power host 4 is placed in the installation space, so that the power host 4 is hoisted to simulate the scenario of the power host 4 being hoisted to the ceiling in actual work.

[0032] Furthermore, such as Figure 2 As shown, and reviewed Figure 1 Each rotary drive component 2 includes a drive motor 21, which is mounted on the mounting base 11. A traction component 3 is connected to the output shaft 211 of the drive motor 21. Specifically, the drive motor 21 drives the output shaft 211 to rotate, thereby the traction component 3 connected to the output shaft 211 will pull the power unit 4 connected to the traction component 3, and the pull of the traction component 3 simulates the load on the power unit 4.

[0033] Furthermore, review Figure 1 The traction assembly 3 includes a bracket 31, a reel 32, and a traction rope 33. The bracket 31 is mounted on the mounting base 11. Both ends of the reel 32 are rotatably mounted on the bracket 31. One end of the traction rope 33 is wound around the reel 32, and the other end of the traction rope 33 is in a free state and is pulled to the support rod 13. One end of the reel 32 is also connected to the output end of the rotary drive 2.

[0034] The bracket 31 supports the reel 32. One end of the reel 32 is connected to the output end of the rotary drive 2, so that the reel 32 can be driven to rotate when the rotary drive 2 rotates. One end of the traction rope 33 is wound on the reel 32, while the other end is in a free state and pulled to the support rod 13. The free end of the traction rope 33 is connected to the power host 4.

[0035] One end of the traction rope 33, in its free state, is connected to the power unit 4. After the rotary drive 2 rotates, it drives the reel 32 connected to its output end to rotate. As the reel 32 rotates, it causes the traction rope 33 to gradually wind around it. During this continuous winding process, the traction rope 33 generates a traction force on the power unit 4, simulating the load on the power unit 4 through the tension of the traction rope 33. The rotary drive 2 can drive the reel 32 to rotate clockwise or counterclockwise, allowing the reel 32 to pull or release the traction rope 33, thereby simulating different loads on the power unit 4.

[0036] Furthermore, review Figure 1 Each support rod 13 is also provided with a pulley 131, and the other end of each traction component 3 in the free state is pulled to the corresponding pulley 131.

[0037] In order to avoid excessive friction when the traction rope 33 pulls the power host 4, a pulley 131 is provided on each support rod 13. The pulley 131 reduces the friction when the traction rope 33 pulls the power host 4.

[0038] Furthermore, review Figure 1 The traction assembly 3 also includes a linkage rope 34, one end of which is connected to a traction rope 33, and the other end of which is connected to another traction rope 33.

[0039] During the winding process of the traction rope 33 by the reel 32, the traction rope 33 will age and its strength will decrease after prolonged use, causing changes in the tension of the traction rope 33. Furthermore, the degree of strength decrease in the traction rope 33 varies depending on the load it is subjected to. When the tension of the traction rope 33 on one side changes, it causes an imbalance in the tension of the traction ropes 33 on both sides of the power unit 4. This can easily cause the rotary drive component 2 connected to the traction rope 33 to be subjected to instantaneous torque impact, leading to damage to the rotary drive component 2. It will also introduce errors into the test results of the power unit 4.

[0040] Therefore, the tension on both sides of the power host 4 is evenly distributed through the linkage rope 34, ensuring the tension of the traction ropes 33 on both sides of the power host 4 is balanced, and increasing the service life of the traction ropes 33.

[0041] Furthermore, review Figure 2 Each rotary drive component 2 also includes a control unit 22, a first measuring unit 23 and a second measuring unit 24. The control unit 22 is electrically connected to the drive motor 21, the first measuring unit 23 and the second measuring unit 24 respectively. One end of the first measuring unit 23 is electrically connected to the drive motor 21. The second measuring unit 24 is disposed on the output shaft 211 of the drive motor 21.

[0042] The control unit 22 is used to collect control signals from the first measuring unit 23 and the second measuring unit 24. It should be noted that the first measuring unit 23 is a current sensor, and the second measuring unit 24 is a torque sensor. One end of the current sensor is electrically connected to the drive motor 21, thereby transmitting the current value of the drive motor 21 to the control unit. The control unit 22 adjusts the current output to the drive motor 21 based on the current value to prevent overload. The second measuring unit 24, as a torque sensor, is connected to the output shaft 211 of the drive motor 21, thereby measuring the torque value of the drive motor 21. The control unit 22 adjusts the torque of the drive motor 21 based on the collected torque value, thereby simulating the working state of the power unit 4. For example, adjusting the torque of the drive motor 21 can simulate the clothesline being unloaded, simulating the clothesline being under standard load, and simulating load conditions of 1, 2, or more times the standard load. Simultaneously, the control unit 22 can also determine whether the traction rope 33 is loose based on the current and torque values. When the traction rope 33 is loose, its tension decreases, causing a drop in the torque of the drive motor 21, thus reducing the current required by the drive motor 21. After collecting the torque value fed back from the first measuring unit 23, the control unit 22 will reduce the current output to the drive motor 21. Therefore, the sudden decrease in torque and the subsequent reduction in current value can be used to determine whether the traction rope 33 has become loose. In this example, a Hall effect current sensor can be used as the current sensor, and a torsion angle phase difference sensor can be used as the torque sensor.

[0043] Furthermore, both the traction rope 33 and the linkage rope 34 are steel wire ropes. Because steel wire ropes have high rigidity and strength, are not easily deformed, and have a long service life, both the traction rope 33 and the linkage rope 34 are made of steel wire ropes.

[0044] Furthermore, the two support rods 13 have the same cross-sectional perimeter. This ensures that the traction rope 33 is horizontal with the power unit 4 when pulling the two ends of the power unit 4, preventing errors during testing of the power unit 4.

[0045] Furthermore, the cross-sectional perimeter of each spool 32 is equal. Equal cross-sectional perimeters of the spools 32 ensure that the tension of the traction rope 33 on both ends of the power unit 4 is the same when the spool 32 is wound around the traction rope 33, preventing errors during testing of the power unit 4.

[0046] In summary, referring to Figure 1In the specific implementation of the test device for this electric clothes drying rack, the free ends of the two traction ropes 33 are connected to the opposite ends of the power unit 4. The output shaft 211 is driven to rotate by the drive motor 21, which in turn drives the roller 32 to rotate. The roller 32 rotates and winds the traction ropes 33, causing the traction ropes 33 to generate a pulling force on the power unit 4, simulating the load borne by the power unit 4 in actual operation. After being pulled up by the two traction ropes 33, the power unit 4 is located in the installation space between the two support rods 13. The traction of the traction ropes 33 achieves the suspension of the power unit 4, thereby simulating the scenario of the power unit 4 being suspended from the ceiling in actual operation.

[0047] Meanwhile, the torque of the drive motor 21 can be adjusted by the control unit 22, the first measurement unit 23 and the second measurement unit 24 to further simulate the no-load state, standard load state and load state of 1 times, 2 times and more than the standard load of the power host 4 in actual operation.

[0048] Thus, this invention utilizes the cooperation of two rotary drive components 2, two traction components 3, and two support rods 13. The two rotary drive components 2, mounted on the mounting base 11, drive the two traction components 3 to pull the power unit 4, thereby suspending the power unit 4. This simulates the working state of the power unit 4 suspended from the ceiling of a residence. The pulling force of the traction components 3 is adjusted by the rotary drive components 2 to simulate the load experienced by the power unit 4 during actual operation. By suspending the power unit 4 for testing, the actual working state of the power unit 4 is better simulated, resulting in more accurate performance test results.

[0049] In summary, the above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
