[0002] In order to ensure the water needs of passengers on trains, it is usually necessary to fill the water tanks of trains at some stations with longer stays.

[0026] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.

[0027] like Figure 1 As shown, the water injection mechanism with auxiliary positioning of this embodiment mainly includes: a first mounting plate 1, a second mounting plate 2, a first bracket 3, a second bracket 4, a first elastic connecting member 5, a second elastic connecting member 6 and a water injection gun 7.

[0028] The first mounting plate 1 is used to connect with the mechanical arm of the automatic water supply device, and the second mounting plate 2 is used to install the water injection gun 7, which is used to connect with the water injection port of the train water tank. The first bracket 3 is connected to the first mounting plate 1, and the first elastic connector 5 is used to elastically connect the second bracket 4 and the first bracket 3 so that the second bracket 4 can be displaced relative to the first bracket 3. The second elastic connector 6 is used to elastically connect the second mounting plate 2 and the second bracket 4 so that the second mounting plate 2 can be displaced relative to the second bracket 4.

[0029] Through the above structure, the water injection mechanism of this embodiment, its water injection gun 7 is indirectly connected to the robotic arm through the first elastic connector 5 and the second elastic connector 6. During the connection with the water tank water injection port, the water injection gun 7 can be smoothly connected to the water injection port with the assistance of the flexible structure, thereby reducing the dependence of the water supply device on the visual positioning system.

[0030] like Figure 2 As shown, the first bracket 3 of this embodiment includes a first side plate 31 and a second side plate 32 which are arranged oppositely, and the second bracket 4 includes a third side plate 41 and a fourth side plate 42 which are arranged oppositely. The first elastic connector 5 includes a first connecting shaft 51, a first spring 52 and a second spring 53. Specifically, the first side plate 31 and the second side plate 32 are located between the third side plate 41 and the fourth side plate 42, the first connecting shaft 51 is simultaneously penetrated on the first side plate 31, the second side plate 32, the third side plate 41 and the fourth side plate 42, the first spring 52 and the second spring 53 are respectively sleeved on the first connecting shaft 51, and the first spring 52 is located between the first side plate 31 and the third side plate 41, and the second spring 53 is located between the second side plate 32 and the fourth side plate 42. The two ends of the first spring 52 are respectively abutted against the first side plate 31 and the third side plate 41, and the two ends of the second spring 53 are respectively abutted against the second side plate 32 and the fourth side plate 42, thereby realizing the elastic connection between the first bracket 3 and the second bracket 4.

[0031] like Figure 2 and Figure 3As shown, the second bracket 4 of this embodiment also includes a connecting plate 43 for connecting the third side plate 41 and the fourth side plate 42, and the second mounting plate 2 is connected to the connecting plate 43. Specifically, the second elastic connecting member 6 includes a second connecting shaft 61, a third spring 62, a fourth spring 63 and a baffle 64. Among them, the second connecting shaft 61 includes a large diameter portion 611, a first small diameter portion 612 and a second small diameter portion 613 connected to each other, and the first small diameter portion 612 and the second small diameter portion 613 are distributed at both ends of the large diameter portion 611. During installation, the first small diameter portion 612 passes through the connecting plate 43 and is fixedly connected to the second mounting plate 2, the third spring 62 is sleeved on the outer wall of the first small diameter portion 612, the baffle 64 is fastened to one end of the second small diameter portion 613 away from the large diameter portion 611, and the fourth spring 63 is sleeved on the second small diameter portion 613 and is located between the large diameter portion 611 and the baffle 64.

[0032] like Figure 2 As shown, the axis directions of the first spring 52 and the second spring 53 are parallel to the X direction, and the axis directions of the third spring 62 and the fourth spring 63 are parallel to the Y direction. That is to say, the first elastic connector 5 elastically connects the second bracket 4 and the first bracket 3 along the X direction, and the second elastic connector 6 elastically connects the second bracket 4 and the second mounting plate 2 along the Y direction, so that the moving range of the water injection gun 7 can be increased, which is more conducive to the alignment of the water injection gun 7 and the water injection port.

[0033] like Figure 1 and Figure 2 As shown, the first side plate 31 and the second side plate 32 are provided with weight-reducing holes. Furthermore, the connecting plate 43 is also provided with weight-reducing holes. In this way, the weight of the first bracket 3 and the second bracket 4 can be greatly reduced, which is conducive to reducing the burden of the robot arm.

[0034] like Figure 1 and Figure 2 As shown, the water injection gun 7 of this embodiment includes a first tube 71 and a second tube 72 which are detachably connected. The end of the first tube 71 which is away from the second tube 72 is used to connect with the water injection port of the water tank. The outer wall of the second tube 72 is provided with a first groove 721. The first groove 721 is provided with a U-shaped buckle 8 for connecting the second tube 72 and the second mounting plate 2. By adopting the method of detachably connecting the first tube 71 and the second tube 72, when the train suddenly starts during the water filling process, the first tube 71 can generate a rotational displacement under the pull of the train water injection port, and at the same time generate an upward component force, which will separate the first tube 71 and the second tube 72, and can effectively reduce the risk of damage to the train water injection port and the water filling device.

[0035] Preferably, if Figure 1 As shown, the inner diameter of one end of the first tube 71 connected to the water injection port gradually increases in a direction away from the second tube 72 .

[0036] Specifically, if Figure 4As shown, a second groove (not shown in the figure) is provided at one end of the first tube 71 connected to the second tube 72, and the second tube 72 is provided with an annular convex rib 722 for engaging with the second groove. The second groove and the convex rib 722 cooperate to realize the detachable connection between the first tube 71 and the second tube 72, and the connection force between the second groove and the convex rib 722 is greater than the insertion and extraction force between the first tube 71 and the water tank water injection port, so as to avoid the phenomenon that the first tube 71 is separated from the second tube 72 when the first tube 71 is normally separated from the water injection port.

[0037] The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
