Description

Technical Field

[0001] This application relates to the field of high-speed trains, and in particular to an anti-corrosion device for the wiring plug of a high-speed train wiper motor. Background Technology

[0002] The windshield wiper system of the CRH1A high-speed train currently suffers from the following problems: 1. Environmental exposure: The wiper motor quick-connect plug is located in the front compartment of the fairing, and is exposed to an environment of oil and water mixtures for extended periods. 2. Protective failure: The original waterproof rubber ring loses its sealing performance due to thermal expansion and contraction, and the waterproof tape is prone to detachment after being soaked in oil and water. 3. Structural defects: The wiring harness path passes through easily leaking holes, and the plug is in a free-dangling state. All of these factors contribute to the wiper motor pins being prone to oxidation and corrosion. The existing method of using tape to wrap the wiper only temporarily solves the water seepage problem; the problem recurs after the tape fails, failing to address the fundamental issue of the installation location. Summary of the Invention

[0003] In view of this, this application provides a corrosion-resistant device for the wiring plug of a high-speed train wiper motor, which can improve the waterproof performance of the connector and reduce the risk of corrosion.

[0004] To achieve the above objectives, this application employs the following technical solution:

[0005] A corrosion-resistant device for a windshield wiper motor connector on a high-speed train is characterized by comprising a panel for fixed installation on a Harmony high-speed train cover plate bracket and a U-shaped closure integrally connected to the panel; the U-shaped closure includes a base plate integrally connected to the panel and extending rearward, a vertical plate integrally connected to the base plate and extending upward, a top plate integrally connected to the vertical plate and extending forward, and two side plates integrally connected to the left and right sides of the vertical plate; the base plate, vertical plate, top plate, and two side plates form a U-shaped groove for placing a first connector of a first wiring and a second connector of a second wiring; each of the two side plates is integrally connected to a wing plate extending in the left and right direction, and each wing plate is provided with a first mounting hole, and a first cable tie is provided on the first mounting hole; the first cable tie on the left and right sides fixes the first wire harness of the first wiring to the first wing plate, and the first cable tie on the other side fixes the second wire harness of the second wiring to the second wing plate, so that the first connector and the second connector are horizontally arranged.

[0006] The aforementioned anti-corrosion device for the wiper motor connector of a high-speed train utilizes a U-shaped closure to form a semi-enclosed U-shaped groove. After connection, the two connectors can be concealed within this groove for protection. Furthermore, the two connectors are arranged roughly horizontally, which reduces water leakage compared to a naturally drooping arrangement, thereby improving the corrosion resistance, water resistance, and reliability of the wiper motor quick connector. The panel is mounted on the Harmony high-speed train cover bracket, raising the mounting position. The Harmony high-speed train cover bracket is already present, requiring no modification to the high-speed train structure, resulting in high device compatibility.

[0007] In some embodiments, the panel is vertically arranged and a positioning plate extending forward is provided at the bottom of the panel. The positioning plate is engaged with the bottom of the Harmony cover plate bracket. A connecting hole is provided in the middle of the panel, and a bolt is provided in the connecting hole to fix the panel and the Harmony cover plate bracket together.

[0008] The positioning plate is supported at the bottom of the Harmony cover plate bracket and serves a positioning function, facilitating the alignment of the connection holes on the panel with the corresponding connection holes on the Harmony cover plate bracket.

[0009] In some embodiments, the panel has multiple second mounting holes below the connection hole, and second cable ties are provided in the second mounting holes to secure the second wiring harness of the second connector to the panel. Since the second connector needs to extend to supply power to other parts after being connected to the first connector, providing second mounting holes on the panel and using second cable ties can secure the wiring harness and eliminate the risk of vibration displacement.

[0010] In some embodiments, the top plate is inclined upwards as it extends from back to front, and the bottom plate is inclined downwards as it extends from back to front. The inclined top and bottom plates form a flow channel, reducing liquid accumulation or flow towards the wiring harness.

[0011] In some embodiments, the top plate and the top plate are tilted at an angle of 15°.

[0012] In some embodiments, the first and second connectors are further wrapped with waterproof tape. Adding waterproof tape provides a double seal.

[0013] In some embodiments, the number of first mounting holes on the wing plate is four, two of which are located above the other two.

[0014] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0015] This application discloses an anti-corrosion device for the wiring plug of a high-speed train wiper motor. A semi-enclosed U-shaped groove is formed by a U-shaped closure, allowing the two wiring connectors to be concealed within the U-shaped groove after connection, thus providing protection. Furthermore, the two wiring connectors are arranged roughly horizontally, which reduces water leakage compared to a naturally drooping design, thereby improving the corrosion resistance, water resistance, and reliability of the wiper motor quick connector. The panel is mounted on a Harmony high-speed train cover bracket, raising the mounting position. The Harmony high-speed train cover bracket is already present, requiring no modification to the high-speed train structure, resulting in high device compatibility. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.

[0021] See Figures 1 to 3 This application provides an anti-corrosion device for the wiring plug of a high-speed train wiper motor, including a panel 2 for fixing on a Harmony high-speed train cover plate bracket 1 and a U-shaped closure 3 integrally connected to the panel 2; the U-shaped closure 3 includes a bottom plate 31 integrally connected to the panel 2 and extending rearward, a vertical plate 32 integrally connected to the bottom plate 31 and extending upward, a top plate 33 integrally connected to the vertical plate 32 and extending forward, and two side plates 34 integrally connected to the left and right sides of the vertical plate 32; the bottom plate 31, the vertical plate 32, the top plate 33 and the two side plates 34 form a device for... The first connector 62 of the first wire 6 and the second connector 72 of the second wire 7 are placed in a U-shaped groove; both side plates 34 are integrally connected with wing plates 35 extending in the left and right direction. Each wing plate 35 is provided with a first mounting hole 351 and a first cable tie 4 is provided on the first mounting hole 351. The first cable tie 4 on the left and right sides fixes the first wire bundle 61 of the first wire 6 to the first wing plate 35, and the first cable tie 4 on the other side fixes the second wire bundle 71 of the second wire 7 to the second wing plate 35, so that the first connector 62 and the second connector 72 are arranged horizontally.

[0022] This anti-corrosion device for the wiper motor connector of a high-speed train uses a U-shaped closure 3 to form a semi-enclosed U-shaped groove. After connection, the two connectors can be concealed within the U-shaped groove for protection. Furthermore, the two connectors are arranged roughly horizontally, which reduces water leakage compared to a naturally drooping design, thus improving the corrosion resistance, water resistance, and reliability of the wiper motor quick connector. The panel 2 is mounted on the Harmony high-speed train cover bracket 1, raising the mounting position. The Harmony high-speed train cover bracket 1 is already present, requiring no modification to the high-speed train structure, resulting in high device compatibility.

[0023] Panel 2 is vertically arranged and has a forward-extending positioning plate 21 at its bottom. The positioning plate 21 is locked at the bottom of the Harmony cover plate bracket 1. A connecting hole 22 is provided in the middle of panel 2, and a bolt 8 is provided in the connecting hole 22. The bolt 8 fixes panel 2 and Harmony cover plate bracket 1 together.

[0024] The positioning plate 21 is supported at the bottom of the harmonic cover plate bracket 1 and serves as a positioning tool to facilitate the connection hole 22 on the panel 2 to be connected with the corresponding connection hole 22 on the harmonic cover plate bracket 1.

[0025] The panel 2 has multiple second mounting holes 23 below the connection hole 22. Second cable ties 5 are installed in the second mounting holes 23 to secure the second wire harness 71 of the second connector 7 to the panel 2. Since the second connector 7 needs to extend out to supply power to other parts after connecting with the first connector 6, the second mounting holes 23 on the panel 2, along with the second cable ties 5, effectively secure the wire harness and eliminate the risk of vibration displacement.

[0026] The top plate 33 is inclined upwards as it extends from back to front, while the bottom plate 31 is inclined downwards as it extends from back to front. The inclined arrangement of both the top plate 33 and the bottom plate 31 forms a flow channel, which reduces liquid accumulation or flow towards the wiring harness.

[0027] The tilt angle of the top plate 33 is 15°.

[0028] The first connector 62 and the second connector 72 are also wrapped with waterproof tape. Adding waterproof tape provides a double seal.

[0029] There are four first mounting holes 351 on the wing plate 35, two of which are located above the other two.

[0030] The following is a brief description of the working process and usage method of the anti-corrosion device for the windshield wiper motor connector of a high-speed train according to the above embodiments:

[0031] After connecting the first connector 62 of the first wire 6 and the second wire 7 of the second wire 7 together and binding them with waterproof tape, place them in the U-shaped groove.

[0032] The first wire harness 61 of the first connector 6 is fixed to the wing plate 35 by the first cable tie 4, and the second wire harness 71 of the second connector 7 is fixed to the wing plate 35. The second wire harness 71 of the second connector 7 extends to the lower panel 2, and is then fixed to the panel 2 by the second cable tie 5, so that it extends outward.

[0033] Finally, the panel 2 is fixed to the harmonic cover plate bracket 1 using bolts 8, completing the installation.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
