DETAILED DESCRIPTION

[0027] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Embodiment: A vacuum cleaner durability testing device, such as Figure 1-Figure 6 As shown, it includes a frame 1 made of aluminum alloy. The aluminum alloy material is lightweight and high-strength and can ensure the supporting strength and structural strength of the frame 1. A driving mechanism, a traction mechanism and two clamping mechanisms are provided on the frame 1. The driving mechanism includes an electric control box 2, a driving motor 3 and a transmission assembly 4. The driving motor 3 is fixedly connected to the top of the frame 1, and the rotating shaft 603 of the driving motor 3 is arranged downward. The transmission assembly 4 includes a rotating rod 401, a traction rod 402, two bearings 403 and a connecting rod 2 404. The rotating rod 401 is provided with a through slot 10 and a through slot 2 11. The length of the through slot 10 is the same as that of the through slot 2 11 and they are vertically connected to each other. The connecting rod 2 404 slides along the length direction of the rotating rod 401. The connecting rod 404 is dynamically connected in the through slot 10, and a square limit block 25 is fixedly connected to the top of the connecting rod 404. The side length of the limit block 25 is greater than the width of the through slot 10. The limit block 25 can limit the connecting rod 404 from falling downward from the through slot 10. A fastener 12 for fixing the connecting rod 404 is provided in the through slot 11, and the fastener 12 consists of a screw 802 and a nut. One end of the rotating rod 401 is fixedly connected to the rotating shaft 603 of the driving motor 3 through the fastener 12. The rotating rod 401 is horizontally arranged along the horizontal direction of the frame 1, so that when the driving motor 3 rotates, it can drive the rotating rod 401 to rotate with the driving motor 3 as the center of the circle. The driving motor 3 is a servo motor, which can achieve high-precision and high-repeatability position, speed and torque control.

[0029] like Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, the outer walls of the two bearings 403 are respectively fixedly connected to the two ends of the traction rod 402, and the inner wall of the bearing 403 at one end of the traction rod 402 close to the rotating rod 401 is clamped on the second connecting rod 404. The traction mechanism includes a connecting rod 1 5 and a sliding assembly 6 that are fixedly connected to each other. The inner wall of the bearing 403 at one end of the traction rod 402 away from the rotating rod 401 is clamped on the connecting rod 1 5. By adjusting the clamping height of the two bearings 403 on the connecting rod 1 5 and the connecting rod 2 404, the traction rod 40 2 is horizontally arranged along the transverse direction of the frame body 1, and two buckles 13 are provided on the connecting rod 1 5 and the connecting rod 2 404. The two buckles 13 are symmetrically arranged on both sides of the bearing 403. The two buckles 13 can limit the bearing 403 from sliding up and down on the connecting rod 1 5 or the connecting rod 2 404. The two bearings 403 make the two ends of the traction rod 402 rotatably connected to the connecting rod 1 5 and the connecting rod 2 404 respectively, so that the traction rod 402 can drive the connecting rod 1 5 to reciprocate when the rotating rod 401 reciprocates.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the sliding assembly 6 includes a connecting plate 1 601, two connecting plates 2 602, a rotating shaft 603 and two rollers 604, one end of the connecting rod 1 5 is fixedly connected to the top surface of the connecting plate 1 601, one end of the two connecting plates 2 602 is symmetrically fixed to the bottom surface of the connecting plate 1 601, both ends of the rotating shaft 603 are fixedly connected to the side of a plurality of connecting plates 2 602 close to each other, and the two rollers 604 are both rotatably connected to the rotating shaft 603, and two supporting rods 14 are symmetrically fixed on the frame 1, and a long strip of sliding groove 15 is provided on the top surface of the supporting rod 14, and the bottom ends of the two rollers 604 are respectively against the bottom surfaces of the plurality of sliding grooves 15, and the length of the traction rod 402 is greater than the length of the rotating rod 401. When the end of the rotating rod 401 away from the driving motor 3 is away from the supporting rod 1 When the rod 14 rotates in the direction, the sliding assembly 6 is pulled by the traction rod 402 to slide on the support rod 14 in the direction close to the driving motor 3. When the rotating rod 401 is rotated in the direction close to the support rod 14 at one end away from the driving motor 3, the traction rod 402 pushes the sliding assembly 6 to slide on the support rod 14 in the direction close to the driving motor 3, thereby achieving the effect of driving the sliding assembly 6 to move back and forth. The width of the roller 604 is smaller than the width of the slide groove 15. Four buckles 13 are provided on the rotating shaft 603, which are used to limit the two rollers 604 to prevent the side walls of the rollers 604 from abutting against the inner walls of the slide groove 15. The two rollers 604 and the two bearings 403 reduce the friction between the transmission assembly 4 and the sliding assembly 6 during movement, thereby reducing the energy consumption of the driving motor 3.

[0031] like Figure 1-Figure 7 As shown, the two clamping mechanisms are symmetrically arranged on the side of the two connecting plates 602 away from each other, the clamping mechanism includes a clamping assembly 7 and a connecting assembly 8, the clamping assembly 7 includes a fixed plate 701, a support plate 1 702, a support plate 2 703, a support plate 3 704, two rubber pads 705 and a spring 706, the same side of the support plate 1 702 and the support plate 3 704 are symmetrically fixed to the side of the fixed plate 701 away from the connecting plate 2 602 along the height direction of the frame body 1, and the two ends of the spring 706 are respectively against the support plate 1 702 and the support plate 2 703. The two support plates 702 and 703 are fixedly connected on the near side, and the support plate 2 703 moves back and forth between the support plate 1 702 and the support plate 2 703 through the compression or stretching of the spring 706. The two rubber pads 705 are respectively fixedly connected to the side of the support plate 2 703 and the support plate 3 704 that are close to each other. The support plate 2 703 is pulled upward and the handle of the vacuum cleaner is placed between the support plate 2 703 and the support plate 3 704. At this time, the pulling force applied to the support plate 2 703 is removed and the rebound force generated by the compression of the spring 706 drives the two rubber pads 705 to clamp the handle of the vacuum cleaner, so that the vacuum cleaner can be connected to the clamping assembly 7.

[0032] like Figure 1-Figure 7 As shown, the two rubber pads 705 are provided with an arc-shaped depression on one side close to each other. The rubber pad 705 has good anti-slip properties and elasticity and can be tightly pressed against the handle of the vacuum cleaner. The fixed plate 701 is provided with a slide groove 4 26 with a T-shaped cross section. A slider 27 is slidably connected in the slide groove 4 26. One end of the slider 27 passing through the slide groove 4 26 is fixedly connected to the support plate 2 703. The slider 27 can limit the displacement of the support plate 2 703 when it moves with the spring 706. A connecting groove 28 is symmetrically provided on the side where the support plate 2 703 and the support plate 3 704 are away from each other. Rubber bands can be set between the support plate 2 703 and the support plate 3 704 through the two connecting grooves 28 to block the long-term test process. The handle of the vacuum cleaner is detached from between the two rubber pads 705, and the resilience of the rubber band further enhances the pressure exerted on the handle of the vacuum cleaner by the two rubber pads 705, thereby stabilizing the height and angle of the vacuum cleaner during the test. The vacuum cleaner can be connected to the clamping assembly 7 by pulling the support plate 703 and putting on the rubber band. It is simple and convenient. A distance scale is provided on one side of the length of the through groove 11 to facilitate fixing the connecting rod 404 at the desired position. The distance between the connecting rod 404 and the driving motor 3 is adjusted to increase or decrease the rotation radius of the rotating rod 401, thereby increasing or decreasing the distance that the sliding assembly 6 is driven to move back and forth on the two support rods 14, thereby adjusting the reciprocating distance of the vacuum cleaner during the test.

[0033] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the connection assembly 8 includes a handle 801, a screw rod 802 and a connecting piece 803, one end of the screw rod 802 is fixedly connected to the handle 801, the connecting plate 702 is provided with a long strip of through slot 3 16 along the height direction of the frame 1, the top of the fixing plate 701 is provided with a through hole, the end of the screw rod 802 away from the handle 801 passes through the through hole and the through slot 3 16, and the connecting piece 803 is threadedly connected to the end of the screw rod 802 passing through the through slot 3 16, so that the handle 801, the fixing plate 701 and the connecting piece 803 can be connected through the screw rod. 802 slides back and forth on the connecting plate 2 602 along the height direction of the frame 1 at the same time. The connecting member 803 is composed of a nut and two connecting blocks 18. The two connecting blocks 18 are symmetrically fixed on the outer wall of the nut along the length direction of the frame 1. A slider 19 is fixedly connected to the side of the connecting block 18 close to the connecting plate 2 602. Two long strip-shaped slide grooves 20 are provided on the side of the connecting plate 2 602 away from the handle 801. The length of the slide grooves 20 is the same as that of the through slot 3 16. The two slide grooves 20 are symmetrically arranged on both sides of the through slot 3 16. The two sliders 1 19 are respectively slidably connected in the two slide grooves 20, so that the handle 801 drives the screw rod 802 to rotate on the connecting member 803 while limiting the rotation of the connecting member 803. A gasket 17 is provided between the handle 801 and the connecting plate 602. The gasket 17 is made of rubber material. When the handle 801 is rotated in the clockwise direction, the screw rod 802 increases the distance from the connecting member 803 through the threaded connection, thereby continuously reducing the distance between the handle 801, the fixing plate 701, the connecting plate 602, the connecting member 803 and the gasket 17 until the handle 801 , the fixed plate 701, the connecting plate 602, the connecting piece 803 and the gasket 17 abut against each other and generate a large pressure to achieve a fixing effect. The handle 801 can be rotated counterclockwise to loosen the handle 801, the fixed plate 701, the connecting plate 602, the connecting piece 803 and the gasket 17, so that the clamping assembly 7 can be detachably connected to the traction mechanism through the connecting assembly 8. When the clamping assembly 7 is fixed to the connecting plate 602 through the connecting assembly 8, the clamping assembly 7 moves together with the sliding assembly 6 with the same moving direction, moving distance and moving speed.

[0034] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8As shown, a simulation board 9 is detachably connected to the bottom of the frame 1, and six grooves 23 are symmetrically opened at the bottom of the frame 1. A pressure rod 24 is detachably connected to two grooves 23 symmetrically arranged along the length direction of the frame 1 through fasteners 12. The bottom surface of the pressure rod 24 is against the top surface of the simulation board 9. The simulation board 9 can be fixed by three pressure rods 24. The floor brush of the vacuum cleaner is against the simulation board 9. The simulation board 9 is any wooden floor, tile, carpet, cement board or floor paint board. According to the required test scenario, a simulation board 9 of suitable material is placed on the frame 1 to test the service life of the floor brush of the vacuum cleaner on different materials. The test height and test angle of the vacuum cleaner can be adjusted by changing the height and angle of the clamping assembly 7 when it is fixed on the connecting plate 2 602, thereby simulating the state of users of different heights holding the vacuum cleaner for vacuuming operations.

[0035] like Figure 1-Figure 6 As shown, a control module and a detection computer are arranged in the electric control box 2, and a control panel 21 is arranged on the outer wall of the electric control box 2.

The control panel 21 is provided with a knob and a plurality of buttons for controlling the drive motor 3 to be powered on, powered off, started, stopped or emergency stopped. When the vacuum cleaner is tested to be exhausted, the working time can be recorded by the detection computer and reflected on the control panel 21, so as to obtain the battery performance of the vacuum cleaner. Sockets 22 are symmetrically arranged on both sides of the frame 1. The detection time and the speed of the drive motor 3 are set through the control panel 21, and the reciprocating distance of the vacuum cleaner is set according to the position of the connecting rod 404 on the through slot 11. The vacuum cleaner can be continuously cleaned by powering it through the charger and the socket 22. The durability of the vacuum cleaner is tested. The detection computer can obtain the number of rotations of the driving motor 3 and the number of movements of the sliding component 6 within the set time, and the service life of the motor and circuit of the vacuum cleaner can be analyzed through the test computer. At the same time, the tightness of the overall structure of the vacuum cleaner can be observed during long-term operation, thereby reflecting the stability of the vacuum cleaner during long-term use. After the test, the service life of the brush roller can be known by observing the degree of wear, so that the durability test of the vacuum cleaner is more comprehensive and the test data is closer to the actual use. Two clamping components 7 can be used to connect two vacuum cleaners of different models for simultaneous testing, which is convenient for comparing the performance of vacuum cleaners of different models. A set of standardized test plans and quality control requirements can be formulated to ensure the quality of the vacuum cleaner.

[0036] like Figure 1-Figure 8 As shown, a method for using a vacuum cleaner durability testing device includes the following steps: S1: Select a test scenario, select a simulation board 9 of a suitable material according to the required test scenario and fix it to the bottom of the frame 1 through a plurality of pressure rods 24 and a plurality of fasteners 12; S2: Connect the vacuum cleaner, place the floor brush of the vacuum cleaner against the simulation board 9, pull the second support board 703 upwards and place the handle of the vacuum cleaner between the second support board 703 and the third support board 704, then remove the tension applied to the second straight board and generate a rebound force when the spring 706 is compressed to drive the two rubber pads 705 to clamp the handle of the vacuum cleaner; S3: Adjust the test angle and test height of the vacuum cleaner, adjust the height and tilt angle of the fixing plate 701 according to the handle height and tilt angle of the vacuum cleaner, turn the handle 801 and fix the fixing plate 701 through the threaded screw 802 and the connector 803; S4: adjusting the moving distance of the vacuum cleaner, adjusting the distance between the second connecting rod 404 and the driving motor 3 to increase or decrease the rotation radius of the rotating rod 401, thereby increasing or decreasing the distance that the traction mechanism is driven to reciprocate on the plurality of support rods 14; S5: Setting detection parameters, setting the detection time, the rotation speed of the drive motor 3, the number of rotations of the drive motor 3, and the reciprocating movement distance of the traction mechanism through the control panel 21; S6: Start and stop, control the drive motor 3 to be powered on, powered off, started, stopped or emergency stopped through a number of buttons or knobs on the control panel 21.
