Description

Technical Field

[0001] The invention relates to a rail vehicle windshield wiper water tank, in particular to a rail vehicle windshield wiper water tank mounting structure. Background Art

[0002] The windshield wiper water tank on a rail vehicle is typically located inside the cover beneath the driver's station and is fixed to the station frame. A water inlet is located on the outside of the station frame, connected to the water tank's fill port via a transition pipe. Because the inlet is located below the station's surface and on the side panel, perpendicular to the ground, it's difficult to adjust the angle of the water tank when adding water. Furthermore, the water tank is restricted by the station's external cover, limiting the filling angle and making it very inconvenient. It's also very easy to spill water.

[0003] At the same time, some vehicles do not have a water filling port on the driver's console frame. Water is added by opening the driver's console maintenance door. Since the water tank is fixed and cannot be moved, and there are other electrical equipment that need to be repaired inside the driver's console, such as connectors and terminal blocks, the water tank cannot be directly fixed in a position facing the maintenance door. In this case, the operator needs to reach into the maintenance door, find the wiper water tank, and add water with a funnel in one hand and a kettle in the other. The operator's line of sight is also blocked, and adding water is basically a blind operation, which is very difficult.

[0004] There is also a fixed water tank installed outside the driver's desk. Although it is more convenient to add water to this water tank than the above two methods, the external water tank is very unsightly. According to the current development of rail vehicles, the appearance of the driver's desk is also very important, and users also pay special attention to it. There are basically no models with external water tanks. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that it is inconvenient to add water to the existing built-in rail vehicle wiper water tank. The present invention provides a rail vehicle wiper water tank installation structure that is easy to use.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A rail vehicle wiper water tank mounting structure includes a water tank and a base, the water tank is mounted on the base, the base includes a fixed mounting frame and a movable mounting frame, the movable mounting frame is slidably mounted on the fixed mounting frame, the water tank is mounted on the movable mounting frame, and a locking structure is installed between the movable mounting frame and the fixed mounting frame. After the locking structure is opened, the water tank slides out of the fixed mounting frame together with the movable mounting frame. When the locking structure is locked, the relative position of the movable mounting frame and the fixed mounting frame is fixed.

[0008] The present invention designs the water tank mounting base as a movable mounting frame and a fixed mounting frame that are slidably mounted together, and provides a locking structure between the movable mounting frame and the fixed mounting frame. When the vehicle is running, the locking structure can be locked to fix the relative positions of the movable mounting frame and the fixed mounting frame, and the water tank can be stored in the lower space of the driver's station away from the inspection door; when the rail vehicle wiper water tank is inconvenient for inspection, maintenance and water addition operations, the locking structure can be opened and the water tank together with the movable mounting frame can be dragged to the inspection door, so that the operator's line of sight will not be blocked, and corresponding inspection, maintenance and water addition operations are convenient; after the maintenance is completed, the water tank is pushed back to its original position and locked, so that it will not block the area of ​​the inspection door, and other equipment inside the driver's station can be inspected conveniently.

[0009] In order to avoid the trouble of operators carrying water adding tools, a funnel assembly is installed on the movable mounting frame.

[0010] Preferably, a connecting rod mounting base is provided on the movable mounting frame, and the funnel assembly includes a connecting rod and a funnel. One end of the connecting rod is connected to the funnel, and the other end is hinged to the connecting rod mounting base. When the connecting rod is rotated relative to the connecting rod mounting base to the water filling port of the water tank, the funnel is connected to the water filling port. This not only avoids the need to carry water adding tools when adding water, but also, when the funnel rotates to the water filling position during water addition, the connecting rod can support the funnel. The operator no longer needs to hold the funnel to add water, thereby freeing the operator's hands. The operator can add water with both hands, avoiding the laborious state of carrying the kettle with one hand, and greatly facilitating maintenance personnel.

[0011] For easy storage, the connecting rod includes multiple sections of rod bodies that are hinged in sequence.

[0012] In a specific embodiment, the locking structure includes a locking plate arranged on the fixed mounting frame, a locking hook hinged on the fixed mounting frame, and a locking hole arranged on the movable mounting frame. When locking, the locking plate is inserted into the locking hole, and the locking hook is buckled into the locking hole on the locking plate.

[0013] In order to make the pulling out of the movable mounting frame more stable and reliable, a guide structure is provided between the fixed mounting frame and the movable mounting frame.

[0014] In a specific embodiment, the guide structure includes a guide hole and a guide groove arranged along the sliding direction on the fixed mounting frame, a guide shaft and a guide roller arranged at the rear end of the movable mounting frame, both ends of the guide shaft pass through the guide holes, and the guide roller is installed at the end of the guide shaft and placed in the guide groove.

[0015] Preferably, a limiting structure is provided in the guide groove so that when the water tank is dragged to the limit of travel, it just reaches the area of ​​the maintenance door, which is convenient for maintenance.

[0016] In a specific embodiment, cross beams are provided at both ends of the fixed mounting frame, and longitudinal mounting brackets are provided on both sides. The cross beams are connected with the longitudinal mounting brackets to form a frame, and the guide holes and guide grooves are provided on the longitudinal mounting brackets.

[0017] In a specific embodiment, a connecting rod mounting seat, a locking hole, a supporting wheel assembly and a handle are provided at the front end of the movable mounting frame.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention provides a water tank mounting base composed of a fixed mounting frame and a movable mounting frame that can slide relative to each other, thereby enabling the water tank to be dragged to the outside during inspection and maintenance, thereby facilitating inspection and maintenance. At the same time, when adding water, the funnel assembly provided with the structure can be unfolded and the funnel can be rotated to the water filling port of the water tank, thereby facilitating water addition and avoiding the trouble of the operator having to carry water adding tools. When the funnel is rotated to the water adding position during water addition, the operator's hands can be freed, and the operator no longer needs to hold the funnel. The operator can add water with both hands while holding the water adding kettle, thereby avoiding the laborious situation of carrying the kettle with one hand. At the same time, the present invention has a locking structure that can lock the water tank and the movable mounting frame while the vehicle is running. When inspection and maintenance and water addition are required, the locking structure can be easily opened, and the water tank can be dragged out together with the movable mounting frame. In addition, the water tank dragging also has a limited structure. When dragged to the travel limit, it just reaches the area of ​​the inspection and maintenance door, thereby facilitating inspection and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention will be further described below in conjunction with specific preferred embodiments, but the scope of protection of the present invention is not limited thereby.

[0033] For the convenience of description, the relative position relationship of each component, such as up, down, left, right, etc., is described according to the layout direction of the drawings in the specification, and does not limit the structure of this patent.

[0034] like Figure 1 As shown, an embodiment of the rail vehicle wiper water tank mounting structure of the present invention includes a base and a water tank 3, the base includes a fixed mounting frame 1 and a movable mounting frame 2, the movable mounting frame 2 is slidably mounted on the fixed mounting frame 1, the water tank 3 is fixedly mounted on the movable mounting frame 2, and a locking structure is provided between the movable mounting frame 2 and the fixed mounting frame 1. After the locking structure is opened, the water tank 3 slides out of the fixed mounting frame 1 together with the movable mounting frame 2 (as shown in FIG. Figure 2 、 Figure 3 As shown), it is convenient for maintenance and water adding operation; when the locking structure is locked, the relative position of the movable mounting frame 2 and the fixed mounting frame 1 is fixed (as shown Figure 1 shown).

[0035] The front end of the movable mounting frame 2 is provided with a funnel assembly. After the water tank is pulled out, the funnel assembly of the water adding auxiliary device of the present structure can unfold the connecting rod. Figure 3 The water tank installation structure does not include the dragged out state of the water tank as shown. Figure 4 As shown, the water addition state is as follows Figure 5 shown.

[0036] like Figure 6 As shown, the fixed mounting frame 1 includes a crossbeam 11, a locking piece 12, a locking hook 13, and a longitudinal mounting bracket 14. The crossbeam 11 and the longitudinal mounting bracket 14 are connected to form a rectangular frame. The locking piece 12 is mounted on the front end of the crossbeam 11, and the locking hook 13 is hingedly connected to the front end of the crossbeam 11. The longitudinal mounting bracket 14 is L-shaped, with a full-length guide hole 141 defined on its inner side and a guide slot 142 disposed outside the guide hole 141.

[0037] like Figure 7 As shown, the movable mounting frame 2 includes two parts: a water tank mounting seat assembly 21 and a funnel assembly 22.

[0038] like Figure 8 As shown, the water tank mounting seat assembly 21 includes a water tank mounting plate 211 for mounting the water tank 3, a roller assembly 212 for guiding and sliding, a connecting rod mounting seat 213 for mounting the funnel assembly 22, a locking hole 214 for locking the movable mounting frame 2, a support wheel assembly 215 for supporting the front end of the movable mounting frame 2, and a handle 216 for dragging the movable mounting frame 2. The roller assembly 212 includes a guide shaft 2121 and a guide roller 2122. Both ends of the guide shaft 2121 pass through the guide hole 141 on the fixed mounting frame 1, and the guide roller 2122 is installed at the end of the guide shaft 2121 and placed in the guide groove 142. This not only realizes the connection between the fixed mounting frame 1 and the movable mounting frame 2, but also can realize the dragging out of the movable mounting frame 2 by utilizing the movement of the guide shaft 2121 in the guide hole 141 and the guide roller 2122 in the guide groove 142, and ensures that the dragging out stroke of the movable mounting frame 2 is stable and reliable during the dragging out process (as shown in FIG. 2 ). Figure 2 - Figure 5 shown).

[0039] like Figure 9 As shown, the funnel assembly 22 includes a funnel 221, an inner connecting rod 222 and an outer connecting rod 223. Auxiliary connecting rods are respectively provided on both sides of the funnel 221. One end of the inner connecting rod 222 is hinged to the auxiliary connecting rod, and the other end is hinged to one end of the outer connecting rod 223. The other end of the outer connecting rod 223 is hinged to the connecting rod mounting seat 213. When the connecting rod of the funnel assembly 22 is unfolded and rotated relative to the connecting rod mounting seat 213, the funnel 221 can be rotated to connect with the water filling port of the water tank 3, which is convenient for adding water. When the connecting rod of the funnel assembly 22 is retracted, the funnel assembly 22 is stored at the front end of the movable mounting frame 2 (as shown in FIG. Figure 7 ).

[0040] The fixed mounting bracket 1 is connected to the vehicle body mounting seat and remains fixed. When adding water or maintaining the water tank, the locking structure must be opened first. Figure 10As shown, the locking piece 12 of the fixed mounting frame 1 passes through the locking hole 214 on the movable mounting frame 2, and the locking hook 13 rotates into the locking hole of the locking piece 12. When the locking mechanism is unlocked, the locking hook 13 is rotated out of the locking hole of the locking piece 12, and then the movable mounting frame 2 is dragged to make the locking piece 12 of the fixed mounting frame 1 disengage from the locking hole 214, thereby dragging the water tank and the movable mounting frame 2 out.

[0041] During the dragging process of the water tank 3, the guide roller 2122 of the roller assembly 212 slides in the guide groove 142 of the longitudinal mounting bracket 14 of the fixed mounting frame 1, and its guide shaft 2121 (roller shaft) moves in the guide hole 141 of the longitudinal mounting bracket 14. When it moves to the front end of the guide hole 141, it is limited and reaches the dragging limit position. During the dragging process, the support wheel assembly 215 slides at the front end, achieving the supporting and sliding functions.

[0042] When the water tank 3 slides to the outside for water filling, the funnel assembly 22 can be unfolded, and the funnel 221 can be rotated to the water filling port of the water tank 3 by rotating the inner connecting rod 222 and the outer connecting rod 223 to facilitate water filling. After water filling is completed, the funnel assembly 22 can be rotated and folded back to its original position.

[0043] Since the position of the water tank 3 changes during maintenance dragging, its pipeline must be reserved with sufficient length to meet the dragging stroke, such as Figure 11 gesture.

[0044] The above is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make many possible changes and modifications to the technical solution of the present invention using the technical content disclosed above, or modify it into an equivalent embodiment with equivalent changes. For example, the guide roller 2122 in the roller assembly 212 can also be replaced with a slider, and the guide groove 142 can be replaced with a slide rail. Therefore, any simple modification, equivalent change, and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of protection of the technical solution of the present invention.
