DETAILED DESCRIPTION
[0026] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model. Embodiment 1:
[0027] Combination Figures 1 to 5, this embodiment provides a multi-functional vehicle-end electrical cross-connection structure, including an integrated footrest frame 1 and a connection seat 2. The connection seat 2 is installed on the integrated footrest frame 1. As Figure 1 and Figure 3 and Figure 4 , the integrated footrest frame 1 includes an upper footrest platform 3, a lower footrest platform 4, and a connecting plate 5. The upper footrest platform 3 is welded to the upper end of the connecting plate 5, and the lower footrest platform 4 is welded to the lower end of the connecting plate 5. When set, the upper footrest platform 3 and the lower footrest platform 4 are distributed on opposite sides of the connecting plate 5, so as to avoid the installed connection seat 2 interfering with the maintenance personnel stepping on the integrated footrest frame 1. The integrated footrest frame 1 is fixed to the coupler 25 through the connecting plate 5.
[0028] As Figure 2 shown, the connection seat 2 includes a fixed seat 6, a docking head 7, a protective shell 8, and a limit fixing member 9. The fixed seat 6 is screwed and installed on the connecting plate 5, and the fixed seat 6 is located below the upper footrest platform 3, which can prevent the maintenance personnel from stepping on and damaging the whole connection seat 2. The docking head 7 is assembled on the fixed seat 6. An insertion slot 10 is opened at the outer end of the docking head 7, and the insertion slot 10 is set to be adapted to the cross-wiring connector 26, so that the cross-wiring connector 26 is inserted into the insertion slot 10. The protective shell 8 is rotatably connected to the top of the docking head 7, and a protective cavity 11 is arranged in the protective shell 8. The protective cavity 11 is used to cooperate with and buckle on the docking head 7. The limit fixing member 9 is rotatably connected to the lower end of the docking head 7, and a limit slot 12 is arranged on the limit fixing member 9. After the cross-wiring connector 26 is inserted into the docking head 7, the limit fixing member 9 is rotated, and the limit slot 12 clamps the protrusion on the cross-wiring connector 26, so that the cross-wiring connector 26 is fixedly connected to the docking head 7.
[0029] Optionally, as Figure 3 and Figure 4 , the connecting plate 5 includes an integrally formed first folding plate 13, a second folding plate 14, and a third folding plate 15. The first folding plate 13 and the third folding plate 15 are fixedly connected by the third side. The included angle formed between the first folding plate 13 and the third folding plate 15 is greater than 90°, aiming to increase the stress area and improve the safety of use by maintenance personnel. The bottom of the upper footrest platform 3 is welded to the upper edges of the first folding plate 13, the second folding plate 14, and the third folding plate 15 respectively, and the lower footrest platform 4 is welded to the first folding plate 13. A rib plate 16 is welded and fixed between the second footrest platform and the first folding plate 13, and the rib plate 16 supports and connects the second footrest platform and the first folding plate 13 respectively, so as to improve the safety of use by maintenance personnel.
[0030] Optionally, the third folding plate 15 is respectively fixedly mounted with pads 17 on the upper and lower sides. The mounting plate on the coupler 25 and the pads 17 are fixedly connected by bolts. The multifunctional vehicle-end electrical jumper structure is assembled on the coupler 25. The purpose of setting the pads 17 is to make the coupler 25 swing during the operation of the vehicle to generate a force on the pads 17, so as to avoid direct action on the integrated pedal frame 1, thereby improving the service life of the multifunctional vehicle-end electrical jumper structure as a whole.
[0031] Optional, such as Figure 2 , a plurality of first elastic limiting strips 18 are arranged on the inner wall of the plug slot 10. The plurality of first elastic limiting strips 18 are arranged at intervals in the inner wall of the plug slot 10. After the jumper connector 26 is inserted into the plug slot 10, each first elastic limiting strip 18 is squeezed and flattened by the jumper connector 26, ensuring that the jumper connector 26 is not worn, and at the same time, the elastic force of the first elastic limiting strip 18 itself abuts against the jumper connector 26, so that the jumper connector 26 is tightly plugged with the docking head 7.
[0032] Optional, such as Figure 2 The limiting fixing member 9 includes an integrally formed cross bar 19, a side bar 20 and a limiting piece 21. The two ends of the cross bar 19 are respectively fixedly connected with a side bar 20. The inner side of the side bar 20 is provided with a limiting piece 21, so that a limiting groove 12 is formed between the side bar 20 and the limiting piece 21. The pin passes through the left and right ends of the side bar 20 and the butt joint 7, and the limiting fixing member 9 is integrally rotatably connected to the butt joint 7.
[0033] Optionally, an operating piece 22 is provided on the cross bar 19, and the operating piece 22 is arranged at the middle position of the cross bar 19. The operating piece 22 extends outward relative to the cross bar 19. The operator can control the limit fixing member 9 to rotate around the pin shaft by toggling the operating piece 22, thereby improving the convenience of operation.
[0034] Optional, such as Figure 2 , a limiting column 23 is extended from each end of the protective shell 8, and the limiting column 23 is matched with the limiting groove 12. When the jumper connector 26 is withdrawn from the docking head 7, the protective shell 8 covers the docking head 7 for protection. To ensure that the protective shell 8 is tightly buckled on the docking head 7 and is not separated due to vibration, the limiting fixture 9 is rotated so that the limiting groove 12 clamps the limiting column 23 to ensure that the protective cover is stably buckled on the docking head 7.
[0035] Optionally, a second elastic limiting strip 24 is provided on the side wall of the protective cavity 11 of the protective shell 8. When the protective shell 8 is buckled on the docking head 7, the second elastic limiting strip 24 squeezes the docking head 7, so that the protective shell 8 and the docking head 7 are tightly buckled, preventing impurities such as rainwater and dust from penetrating into the plug slot 10 and affecting the use effect of the jumper connector 26. Embodiment 2:

The coupler 25 is an essential connection structure for connecting two car bodies in a rail vehicle. The two car bodies are connected by the coupler 25. The circuit transmission between the car bodies is interconnected and transmitted through a jumper connector 26. The multi-functional car-end electrical bridging structure is assembled on the coupler 25 and can store the jumper connectors 26 connected to the car body after uncoupling. This embodiment adopts the same multi-functional car-end electrical bridging structure as that in the first embodiment, so its effects are the same as those described in the first embodiment and will not be elaborated here.
