Description

Technical Field

[0001] This invention relates to the field of control equipment technology, and in particular to a novel waterproof driver controller for the Fuxing high-speed train. Background Technology

[0002] The driver controller's waterproof technology primarily achieves environmental protection through structural sealing, material selection, and design optimization. Precision sealing elements such as rubber O-rings and silicone gaskets are used to fill interface gaps and prevent moisture penetration. The housing adopts an integrated molding or labyrinthine groove design to guide liquid away from internal components and promote drainage. At the same time, surface treatment processes such as spraying hydrophobic coatings or using engineering plastics to enhance corrosion resistance work together to prevent moisture intrusion, avoid electrical short circuits and mechanical failures, and ensure that the controller maintains stable performance under humid or splashing conditions.

[0003] Existing waterproof technology for driver controllers has the following technical pain points: due to insufficient sealing structure and material selection, when the Fuxing bullet train is running at high speed in a humid and dusty environment, external liquids and dust can easily enter the equipment through gaps in the handle shaft, button interfaces, or cable connections. If operators violate regulations by bringing liquid beverages into the driver's cab and accidentally spill them on the control panel, they can cause internal electrical components such as the QKW5 slew switch to become damp and short-circuit, or the encoder coupling to become stuck due to dust accumulation. This can lead to signal output errors or command failures. For example, during rainy season operations, rainwater can penetrate and corrode the circuit board, causing traction signal interruption, or dust in windy and sandy environments can interfere with the accuracy of the cam unit's movement, resulting in braking command delays. This significantly increases the frequency of electrical faults and the risk to driving safety. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention provided by various embodiments will be described in detail below with reference to the accompanying drawings. To better understand the purpose of the present invention, the present invention will be described in further detail below.

[0040] Please see Figures 1 to 7 The present invention provides a novel waterproof driver controller for Fuxing high-speed trains, comprising a main control unit assembly 1, a cam unit assembly 2, a mode selection assembly 3, a base plate assembly 4, a cover 5, an encoder protection module 6, a protective plate I 7, a protective plate II 8, a rubber pad 9, a fastening screw 10, a cover fastening screw 11, an upper wire clamp 12, a lower wire clamp 13, a wire clamp rubber pad 14, a pressure plate 15, and an encoder 16.

[0041] The main control unit assembly 1, the cam unit assembly 2, the mode selection assembly 3, and the encoder protection module 6 are fastened to the base plate assembly 4 by the fastening screws 10.

[0042] The cover 5 is fixed to the base plate assembly 4 by the cover fastening screws 11 and the rubber pads 9;

[0043] The upper wire clamp 12 and the lower wire clamp 13 are mounted on the base plate assembly 4. The wire clamp rubber pad 14 is provided between the upper wire clamp 12 and the lower wire clamp 13. The cable connection end face is sealed by the clamping plate 15.

[0044] The encoder 16 is disposed at one axial end of the cam unit assembly 2, and the encoder protection module 6 is provided on the outside of the encoder 16;

[0045] The protective plate I7 ​​and the protective plate II8 are disposed above the slew switch and the encoder connector.

[0046] The new waterproof driver controller for the Fuxing bullet train is a device specifically designed for rail transit control systems. It aims to improve waterproof performance and operational reliability through optimized sealing structure and component layout. The controller consists of a main control unit assembly 1, a cam unit assembly 2, a mode selection assembly 3, a base plate assembly 4, a cover 5, an encoder protection module 6, protective plate I 7, protective plate II 8, rubber pads 9, fastening screws 10, cover fastening screws 11, upper wire clamp 12, lower wire clamp 13, wire clamp rubber pads 14, a pressure plate 15, and an encoder 16. Through systematic integration, these components enable precise transmission of commands for traction, braking, and mode selection, while simultaneously preventing the intrusion of external liquids and dust.

[0047] The main control unit assembly 1, cam unit assembly 2, mode selection assembly 3, and encoder protection module 6 are securely connected to the base plate assembly 4 via fastening screws 10. The main control unit assembly 1 includes two side plates, a handwheel shaft, a handwheel, a handle lever, a speed-regulating drive gear, a self-resetting ratchet, a control ratchet, a switch mounting bracket, and a QKW5 quick-acting switch. The handwheel shaft is fixed between the two side plates, and the handwheel and handle lever are mounted on the handwheel shaft. The driver drives the speed-regulating drive gear to rotate by pushing or pulling the handle. The cam of the cam unit assembly 2 is linked to the driven gear of the main control unit assembly 1, driving the QKW5 quick-acting switch to operate and output an on / off signal during movement. The mode selection assembly 3 provides switching between speed control mode and level control mode, and the encoder protection module 6 provides external protection for the encoder 16. The base plate assembly 4 serves as the basic frame, and the fastening screws 10 ensure the positioning and stable connection of each component, helping to maintain the overall structural rigidity and distribute operating stress.

[0048] The housing 5 is secured to the base plate assembly 4 using housing fastening screws 11 and rubber gaskets 9. The housing 5, made of stainless steel, covers the exterior of the controller, forming the first line of defense against water damage. The rubber gaskets 9 fill the mating surfaces of the housing 5 and the base plate assembly 4, achieving a seal through compression deformation, effectively preventing liquid penetration from the top or sides. This securing method creates a continuous sealing interface between the housing 5 and the base plate assembly 4, enhancing the overall protection level.

[0049] The upper clamp 12 and lower clamp 13 are mounted on the base plate assembly 4, with a clamp gasket 14 between them. The cable connection end face is pressed and sealed by the clamping plate 15, and sealing sponge is wrapped around the contact area between the cable and the upper and lower clamps 12 and 13. The clamp gasket 14 and the clamping plate 15 work together to provide multi-layer sealing for the cable inlet, preventing moisture from entering the internal circuit along the cable surface. The upper clamp 12 and lower clamp 13 are fastened to the base plate assembly 4 with fixing screws to ensure the mechanical stability of the cable connection.

[0050] The encoder 16 is located at one axial end of the cam unit assembly 2, and an encoder protection module 6 is provided on the outside of the encoder 16. The encoder 16 is synchronously connected to the control ratchet of the main control unit assembly 1 via a coupling, converting the mechanical displacement of the handle into an electrical signal output. The encoder 16 adopts two sets of 9-bit Gray code encoders with redundant configuration. Each set of encoders is independently powered, and the output signals are synchronized, reducing the risk of control errors caused by single-point failures. The encoder protection module 6 is wrapped around the encoder 16 to protect it from impact and contaminants, extending the service life of the encoder 16.

[0051] Protective plates I7 and II8 are positioned above the slew switch and encoder connector. Protective plate I7 ​​covers the QKW5 slew switch, and protective plate II8 covers the encoder connector, providing physical isolation to prevent direct contact with external objects or liquid splashes onto sensitive electrical components. Protective plates I7 and II8 are secured to the base plate assembly 4 or the main control unit assembly 1 with fasteners, enhancing local protection and reducing signal interference caused by accidental impacts.

[0052] Specifically, the waterproof driver controller for the Fuxing bullet train includes a main control unit assembly 1 comprising two side plates, a handwheel shaft, a handwheel, a handle lever, a speed regulating drive gear, a self-resetting ratchet, a control ratchet, a switch mounting bracket, and a QKW5 quick-acting switch.

The handwheel shaft is fixed between the two side plates, the handwheel is fixed to the handwheel shaft, and the handle lever is fixed to the handwheel. The driver drives the handwheel shaft to rotate by pushing or pulling the handle. The speed-regulating drive gear is located at the bottom of the handwheel shaft and meshes with the driven gear of the cam unit assembly 2, converting the linear motion of the handle into the rotational motion of the cam unit assembly 2. The self-resetting ratchet and the control ratchet are located on the speed-regulating cam shaft and cooperate with the positioning component to provide damping force and gear positioning during the movement of the main control handle, ensuring stable operation. The QKW5 quick-action switch is mounted on the side plate via the switch mounting bracket and is driven by the cam of the cam unit assembly 2. The concave and convex contours of the cam control the opening and closing of the quick-action switch contacts, outputting an on / off signal. The integrated design of the main control unit assembly 1 closely links mechanical motion with electrical signal output, improving control accuracy.

[0058] Specifically, in the aforementioned waterproof driver controller for the Fuxing bullet train, the encoder 16 is synchronously connected to the control ratchet via a coupling;

[0059] The encoder 16 consists of two sets of 9-bit Gray code encoders, which are redundant and powered independently.

[0060] The encoder 16 of this invention is synchronously connected to the control ratchet of the main control unit assembly 1 via a coupling. The encoder 16 converts the angular displacement of the control ratchet into an electrical signal output. The encoder 16 employs two sets of 9-bit Gray code encoders with redundant configuration. Each set of encoders is independently powered, and the output signals are synchronized. The redundancy design reduces the risk of single-point failure, the Gray code output reduces signal errors, and the direct coupling of the encoder 16 to the control ratchet via the coupling ensures the real-time performance and accuracy of signal acquisition. The encoder protection module 6 is encased outside the encoder 16, providing physical protection. The redundancy and independent power supply scheme of the encoder 16 enhance the reliability of the driver controller.

[0061] Specifically, the waterproof driver controller for the Fuxing bullet train includes a mode selection component 3 comprising a mounting plate, a sealing gasket, and a button switch.

[0062] The mounting plate is provided with a push-button switch mounting hole and a sealing gasket mounting groove, and the sealing gasket is disposed in the sealing gasket mounting groove;

The mounting plate is connected to the base plate component 4 via a mounting post. The push-button switch is fixed to the mounting plate, and the driver switches between speed control mode and level control mode by pressing the push-button switch. The sealing gasket fills the gap between the push-button switch and the mounting plate, preventing liquid intrusion, and the mounting post provides structural support. The sealing design of the mode selection component 3 ensures the normal operation of the push-button switch in humid environments.

[0065] Specifically, in the aforementioned waterproof driver controller for the Fuxing bullet train, the base plate assembly 4 is provided with the rubber pad 9, and the upper wire clamp 12 and the lower wire clamp 13 are fastened to the base plate assembly 4 by fixing screws;

A wire clamp rubber pad 14 is provided between the upper wire clamp 12 and the lower wire clamp 13, and the cable connection end face is pressed and sealed by a pressure plate 15. The contact parts between the cable and the upper wire clamp 12 and the lower wire clamp 13 are wrapped with sealing sponge, and the multi-layer sealing structure prevents moisture from penetrating along the cable surface into the interior of the base plate assembly 4. The fixing method of the upper wire clamp 12 and the lower wire clamp 13 ensures the mechanical stability of the cable connection, the base plate assembly 4 acts as a basic frame to distribute operating stress, and the rubber pad 9 further strengthens the seal between the cover 5 and the base plate assembly 4.

[0068] Specifically, the waterproof driver controller for the Fuxing bullet train has a cover 5 made of stainless steel, which is pressed and fixed to the base plate assembly 4 by the cover fastening screws 11 and the rubber pads 9.

[0069] The main control unit assembly 1 has sealing gaskets on the top and sides of its side plate.

[0070] The housing 5 of this invention is made of stainless steel and is secured to the base plate assembly 4 by housing fastening screws 11 and rubber gaskets 9. Sealing gaskets are provided on the top and sides of the side plates of the main control unit assembly 1. The housing 5 covers the outside of the controller, forming the first waterproof barrier. The rubber gaskets 9 compress and deform to fill the mating surface between the housing 5 and the base plate assembly 4, achieving a continuous seal. The side plate sealing gaskets prevent liquid from entering from the handle rotation area. The stainless steel housing 5 provides corrosion resistance, the fastening screws 11 ensure the stable installation of the housing 5, and the sealing components work together to improve the overall waterproof rating.

[0071] Specifically, in the aforementioned waterproof driver controller for the Fuxing high-speed train, the protective plate I7 ​​and the protective plate II8 are respectively located above the slew switch and above the encoder connector;

[0072] The protective plate I7 ​​and the protective plate II8 are fixed to the base plate assembly 4 or the main control unit assembly 1 by fasteners.

[0073] The protective plates I7 and II8 of this invention are respectively disposed above the quick-acting switch and the encoder connector, and are fixed to the base plate assembly 4 or the main control unit assembly 1 by fasteners.

The installation positions of protective plates I7 and II8 are targeted at sensitive electrical components, reducing signal interference caused by accidental collisions or contamination, and enhancing local protection capabilities.

[0074] This invention addresses the problem of insufficient waterproofing in existing driver controllers, leading to electrical malfunctions, signal output errors, and increased driving safety risks due to liquid and dust intrusion. It achieves multi-layered protection by optimizing the sealing structure and component layout. The new waterproof driver controller for the Fuxing bullet train employs an integrated sealing design between the housing 5 and the base plate assembly 4. The housing 5, made of stainless steel, is firmly fixed to the base plate assembly 4 using housing fastening screws 11 and rubber gaskets 9. The rubber gaskets 9 compress and deform at the joint surface to form a continuous sealing interface, effectively preventing external liquids from penetrating from the top or sides. Sealing gaskets are provided on the top and sides of the side plate of the main control unit assembly 1 to fill the gaps at the handle rotation points, preventing moisture intrusion from moving parts. Upper cable clamps 12 and lower cable clamps 13 are mounted on the base plate assembly 4. A cable clamp rubber gasket 14 is provided between the upper and lower cable clamps 12 and 13. The cable connection end face is sealed by a clamping plate 15.

This physical isolation prevents liquid splashes or dust accumulation on sensitive electrical components. An encoder protection module 6 is located on the outside of the encoder 16, providing localized protection. The encoder 16 is synchronously connected to the control ratchet of the cam unit assembly 2 via a coupling, and employs two sets of 9-bit Gray code encoders that are redundant and independently powered. This redundancy design reduces the risk of signal errors caused by single-point failures. The mounting plate of the mode selection assembly 3 has push-button switch mounting holes and sealing gasket mounting grooves. The sealing gasket fills the grooves to prevent liquid intrusion at the button interface. The cam unit assembly 2 drives the QKW5 quick-acting switch, and the output signal is transmitted through a sealed connector.

Testing has shown that this design effectively prevents liquid and dust intrusion, maintains stable operation of the driver controller in complex environments, reduces electrical short circuits and mechanical failures, thereby reducing driving safety risks. The installation of protective plates I7 and II8 enhances local protection for the slew switch and encoder connector. The encoder protection module 6 encloses the encoder 16 to protect it from external impacts and contaminants. The wire clamp system, through the compression and sealing of the upper wire clamp 12, lower wire clamp 13, and wire clamp gasket 14, prevents moisture penetration along the cable.
