[0002] With the continuous improvement of science and technology, smart homes are appearing more and more in people's lives and are loved by most modern people. Electric blinds, as one of the representatives of smart homes, have brought a lot of convenience to people's lives. The blinds motor is output through the power output shaft of the motor movement after being decelerated by the reducer, becoming the power output end of the entire blinds motor, driving the blinds' cord winder to rotate, thereby driving the blinds' curtain leaves to flip and realize the blinds' shading function.

[0003] Currently, motor performance testing generally requires a performance test bench. This bench has a rotating shaft connected to the load and motor at both ends, and is equipped with detection devices to collect various parameters during motor output. The motor needs to be fixed to the rotating shaft using various brackets.

This is quite troublesome. Therefore, it is particularly important to improve existing test benches and design a new Venetian blind motor durability test bench to address the above technical shortcomings and improve the practicality of the overall test bench.

[0021] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Example:

[0023] See also Figures 1-4 , the utility model provides a technical solution:

[0024] A Venetian blind motor durability test bench includes a test bench body 1, a movable seat 2 is slidably connected to the top of the test bench body 1, a limit assembly 3 is provided on the outer side of the movable seat 2, a positioning assembly 4 is provided on the end of the test bench body 1 close to the movable seat 2, and an encoder 5 is provided on the end of the test bench body 1 away from the positioning assembly 4, and a hysteresis brake 6 is provided on the outer side of the encoder 5;

[0025] The limiting component 3 is used to limit the blind motor, and the limiting component 3 consists of a connecting plate 7, a limiting block 8, and a rotating ring 9. The connecting plate 7 is located at the end of the moving seat 2 close to the positioning component 4, and multiple groups of limiting blocks 8 are all located at the end of the connecting plate 7 close to the moving seat 2. The rotating ring 9 is located at the end of the multiple groups of limiting blocks 8 away from the connecting plate 7.

[0026] Furthermore, a guide groove 10 is provided inside the limit block 8, and a guide rod is provided at one end of the rotating ring 9 close to the limit block 8. The external structure size of the guide rod is designed to correspond to the internal structure size of the guide groove 10. The rotating ring 9 is connected to the guide groove 10 through the guide rod, and the guide rod and the guide groove 10 are slidably connected so that the guide rod can be connected to the limit block 8. When the rotating ring 9 rotates, it drives multiple groups of guide rods to move, and the limit block 8 can be moved through the guide groove 10.

[0027] Among them, multiple groups of meshing blocks 11 are provided on the outside of the rotating ring 9, and a driving gear 12 is rotatably connected to the inside of the connecting plate 7 and one end close to the rotating ring 9. The driving gear 12 is meshed with the meshing block 11, and the inside of the driving gear 12 is fixedly connected to the driving end of the driving motor. When the driving motor is started, the driving gear 12 is driven to rotate, so that the multiple groups of meshing blocks 11 can be displaced, driving the rotating ring 9 to rotate.

[0028] Secondly, the positioning assembly 4 is composed of a positioning block 13, a first rotating rod 14, a second rotating rod 15 and a rotating block 16. Multiple groups of positioning blocks 13 are slidably connected to the top of the test bench body 1 and close to one end of the limit assembly 3. The first rotating rod 14 is rotatably connected to the outside of the positioning block 13 and is located inside the test bench body 1. The second rotating rod 15 is rotatably connected to the end of the first rotating rod 14 away from the positioning block 13. The positioning block 13 is located between multiple groups of second rotating rods 15. When the limit assembly 3 is connected to the venetian blind motor and the venetian blind motor is limited, the venetian blind motor can be positioned through the positioning assembly 4, thereby facilitating the connection of the limit assembly 3 to the venetian blind motor and limiting the venetian blind motor.

[0029] Furthermore, a sliding groove 17 is provided inside the test bench body 1 and on the outside of the positioning block 13. The internal structure and size of the sliding groove 17 are designed to correspond to the external structure and size of the positioning block 13. The positioning block 13 is connected to the test bench body 1 through the sliding groove 17. The positioning block 13 is slidably connected to the sliding groove 17 so that the positioning block 13 can be slidably connected to the test bench body 1. The sliding groove 17 can guide the positioning block 13 to prevent the positioning block 13 from offsetting.

[0030] Furthermore, the second rotating rod 15 is rotatably connected to the rotating block 16. A telescopic cylinder is provided inside the test bench main body 1 and below the rotating block 16. The driving end of the telescopic cylinder is rotatably connected to the positioning block 13. When the telescopic cylinder is started, the positioning block 13 is driven to move, so that the second rotating rod 15 can be moved, driving the first rotating rod 14 to move, thereby causing the rotating block 16 to rotate, driving the remaining second rotating rods 15 to rotate, causing the connected first rotating rods 14 to rotate, thereby causing multiple groups of positioning blocks 13 to move.

[0031] Furthermore, the encoder 5 is provided with a parallel slit coupling 21 at one end close to the hysteresis brake 6, and a connecting shaft 18 is provided at the end of the parallel slit coupling 21 away from the encoder 5. The end of the connecting shaft 18 away from the parallel slit coupling 21 is provided with a double diaphragm series coupling 19, and the end of the hysteresis brake 6 away from the double diaphragm series coupling 19 is provided with a plum blossom coupling 20. The encoder 5, the connecting shaft 18 and the hysteresis brake 6 are all connected to the test bench body 1 through a connecting frame, and the drive shaft of the venetian blind motor is connected to the plum blossom coupling 20. Through the hysteresis brake 6, in combination with the double diaphragm series coupling 19, the connecting shaft 18 and the parallel slit coupling 21, the venetian blind motor can be subjected to a durability test through the encoder 5.

[0032] In this embodiment, the implementation scenario is specifically as follows: in actual use, the telescopic cylinder is started between the blind motor and the multiple sets of positioning blocks 13, driving the positioning blocks 13 to move, so that the second rotating rod 15 can move, driving the first rotating rod 14 to move, thereby causing the rotating block 16 to rotate, driving the remaining second rotating rods 15 to rotate, so that the connected first rotating rods 14 rotate, thereby causing the multiple sets of positioning blocks 13 to move, positioning the base of the blind motor, moving the moving seat 2 to the outside of the blind motor, and starting. The driving motor drives the driving gear 12 to rotate, so that multiple groups of meshing blocks 11 can be displaced, and the rotating ring 9 is driven to rotate. When the rotating ring 9 rotates, multiple groups of guide rods are driven to be displaced, and the limit block 8 is displaced through the guide groove 10. The limit block 8 is displaced to the outside of the venetian blind motor, and the venetian blind motor is limited. When the venetian blind motor is tested, it can prevent the venetian blind motor from being offset, which affects the test effect. Compared with the existing test bench, the utility model can improve the overall practicality of the test bench through design.
