Traditionally, the testing of these key components mostly relies on manual operation, including the rotation force and coverage test of the brush disc, and the evaluation of the fit and stain removal ability of the scraper bar. However, this testing method has many shortcomings: first, manual testing is difficult to achieve high precision and consistency, and the test results are easily affected by the subjective judgment of the operator; second, it is inefficient and cannot meet the needs of rapid quality control in large-scale production; third, long-term manual operations are prone to fatigue errors, affecting the accuracy and reliability of the test.

[0020] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0021] This embodiment provides a life test device for a cleaning structure of a sweeper, such as Figures 1 to 3 , comprising a central pillar 1, at least one rotating bracket 2 and at least one set of rotating drive components, wherein the rotating drive components are mounted on the central pillar 1, one end of the rotating bracket 2 is connected to a sweeping vehicle to be tested, and the other end of the rotating bracket 2 is drivingly connected to an output end of the rotating drive component, and the rotating drive component is used to drive the rotating bracket 2 to rotate around the central pillar 1 to control the movement of the sweeping vehicle.

[0022] Specifically, Figure 1 As shown, the central pillar 1 is fixed to the ground, and the central pillar 1 is used as the center of movement of the sweeping vehicle. The sweeping vehicle is controlled to move in a circle within the length range of the rotating bracket 2 to realize automatic wear test of the cleaning structure of the sweeping vehicle, that is, life test. By controlling the movement of the sweeping vehicle, the test result closest to the actual can be obtained.

[0023] Among them, the rotating drive assembly of this embodiment includes a connecting member 3, a conductive ring 4 and a bearing 5, the conductive ring 4 is installed on the central pillar 1, the bearing 5 is sleeved on the central pillar 1, the connecting member 3 is installed on the output end of the conductive ring 4, and the connecting member 3 and the bearing 5 are both fixedly connected to the rotating bracket 2.

[0024] Specifically, Figure 3As shown, the conductive ring 4 of this embodiment is the prior art. Through the characteristics of the conductive ring 4, the phenomenon of wire entanglement in the process of driving the rotating bracket 2 to rotate can be avoided. The rotating bracket 2 can be fixed to the connecting piece 3 by welding, and the conductive ring 4 drives the connecting piece 3 to rotate, and the connecting piece 3 can drive the rotating bracket 2 to rotate. Furthermore, in order to ensure smooth rotation, the rotating bracket 2 is also connected to a bearing 5, and the bearing 5 preferably adopts a self-aligning bearing. The so-called self-aligning bearing refers to a bearing 5 whose ring raceway is spherical and can adapt to the angular deviation movement between the axis lines of the inner and outer raceways. It mainly bears radial loads and can also bear a small amount of bidirectional axial loads. Therefore, during the rotation of the rotating bracket 2, a radial force may be generated on the bearing 5, and the self-aligning bearing can automatically adjust to ensure the smooth rotation of the rotating bracket 2, thereby allowing the sweeper to move smoothly.

[0025] Furthermore, in order to improve the efficiency of detection, the rotating bracket 2 of this embodiment can be set to two or more than two, such as Figure 1 and Figure 2 As shown, in this embodiment, two rotating brackets 2 are taken as an example, and two groups of rotating drive components are correspondingly provided. In order to ensure that the two rotating brackets 2 can rotate synchronously, a synchronization component is provided to prevent the collision of the two sweepers. The synchronization component includes a synchronization link 6 and a fixing member 7. The rotating bracket 2 is provided with the fixing member 7. The two ends of the synchronization link 6 are respectively provided on different fixing members 7. Specifically, as shown in FIG. Figure 1 As shown, the two rotating brackets 2 are connected by a synchronous connecting rod 6 so that the two rotating brackets 2 are linked. Therefore, when the conductive ring 4 is started at the same time, the two rotating brackets 2 can also rotate synchronously, and the two sweepers can perform the test work in an orderly manner.

[0026] like Figure 1 and Figure 4 The sweeping vehicle of the present embodiment is equipped with a connecting assembly, which includes a connecting rod 8 and a locking piece 9. One end of the connecting rod 8 is welded to the sweeping vehicle, and the rotating bracket 2 is provided with a hollow connecting tube 10. The hollow connecting tube 10 is sleeved on the outer periphery of the connecting rod 8, and the hollow connecting tube 10 is locked to the connecting rod 8 by the locking piece 9.

[0027] Specifically, the sweeping vehicle of this embodiment is mainly used for testing, so for the convenience of assembly, a connecting assembly is installed on the sweeping vehicle, and one end of the connecting rod 8 can be fixed to the sweeping vehicle by welding, or can be locked to the sweeping vehicle by screws, etc., according to actual needs. During assembly, the connecting rod 8 is inserted into the hollow connecting tube 10 of the rotating bracket 2, and then locked by the locking member 9 to complete the assembly work. The structure is simple and the disassembly and assembly are convenient.

[0028] The present embodiment may further include a position sensor (not shown in the drawings) to detect the moving position of the sweeper. When the sweeper moves to a position where it is required to stop, such as when it reaches a drainage position, the controller (not shown in the drawings) controls the conductive ring 4 to stop working according to the signal of the position sensor so that the sweeper can drain water. After the drainage work is completed, the controller controls the conductive ring 4 to continue working and the sweeper continues to move.

[0029] As another implementation of this embodiment, this embodiment can also drive the central pillar 1 to rotate by setting a motor, and the rotating bracket 2 is fixed to the central pillar 1. The central pillar 1 drives the rotating bracket 2 to rotate, which can also achieve the purpose of driving the sweeper to move automatically, as long as the structure of the central pillar 1 can be stabilized.

[0030] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the utility model, which does not depart from the content of the technical solution of the utility model, belongs to the scope of the technical solution of the utility model.
