Description

Technical Field

[0001] This utility model relates to the field of rail transit electrical equipment technology, and in particular to a control cabinet structure for EMU assembly. Background Technology

[0002] In rail transit equipment such as high-speed trains, the control cabinet serves as the core carrier of the electrical control system, integrating a large number of electrical components, controllers, and a complex network of cables. During long-term operation, traditional high-speed train control cabinets suffer from issues with wiring and cable management. The terminal blocks or junction boxes in traditional control cabinets have relatively simple structures, and they typically lack effective and flexible clamping and securing devices for inserted cable connectors. This leads to cable connectors easily loosening or even detaching under dynamic conditions such as vibration and impact during train operation, causing poor contact, signal interruption, or power outages, seriously threatening train safety. Furthermore, the chaotic cable layout within the cabinet, lacking necessary organization and securing mechanisms, not only hinders maintenance but also allows the messy cables to interfere with each other, accumulate heat, and potentially cause short circuits due to wear.

[0003] Therefore, this application provides a control cabinet structure for high-speed train assembly to meet the requirements. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a high-speed train assembly control cabinet structure.

[0005] The technical problem to be solved by this utility model is to provide a control cabinet structure for high-speed trains, which solves the problems of loose cable joints, chaotic internal cable management, and poor overall layout caused by vibration in existing control cabinets.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A control cabinet structure for a high-speed train includes a cabinet body, on which a display screen and a cabinet door are mounted, and on the cabinet door a handle is mounted. Inside the cabinet body are installed a shunt fuse group, a wiring mechanism, a controller, and a clamping mechanism. The clamping mechanism includes a junction box, a mounting slot, a soft pad, a spring, a clamping block, a locking block, a spring, and a locking rod. The junction box is located inside the cabinet body, the mounting slot is formed on the junction box, the soft pad is placed on the inner wall of the mounting slot, the spring is placed inside the mounting slot, the clamping block is connected to the spring, the locking block is placed on the clamping block, and the spring and locking rod are fitted onto the junction box and correspond to the locking block.

[0007] Preferably, the cable management mechanism includes a slide rod, a slider, a connecting groove, and a cable management block. The slide rod is connected to the inner wall of the cabinet, the slider is slidably mounted on the slide rod, the connecting groove is formed on the slider, and the cable management block is mounted on the slider and corresponds to the connecting groove.

[0008] Preferably, there are two displays, both installed on the upper part of the cabinet.

[0009] Preferably, there are multiple shunt fuse groups, all installed inside the cabinet at the bottom.

[0010] Preferably, the controller is installed inside the cabinet and above the cable management mechanism.

[0011] Preferably, the soft pad is made of rubber and is disposed on the inner wall of the mounting groove.

[0012] Preferably, one end of the spring is connected to the inner wall of the mounting groove, and the other end is connected to the clamping block.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects:

[0014] In the above solution, a unique clamping mechanism is used, utilizing the elasticity of the spring sheet in conjunction with the clamping block and soft pad, to provide a flexible yet stable clamping force for the cable connector. The cooperation of the clamping block with the spring and clamping rod further locks the clamping state, effectively preventing the connector from loosening or falling off under continuous train operation and vibration conditions, greatly improving the reliability of the electrical connection and the safety of train operation.

[0015] In the above solution, the cable management mechanism allows the cable bundles to slide and be positioned flexibly along the slide bar. Combined with the connecting slots, this enables the classification, organization, and centralized fixing of the complex cables within the cabinet. This not only makes the cabinet layout neat and aesthetically pleasing and reduces the risk of mutual interference and wear between cables, but also facilitates subsequent troubleshooting, cable replacement, and maintenance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5A control cabinet structure for a high-speed train includes a cabinet body 1, a display screen 2 and a cabinet door 3 mounted on the cabinet body 1, and a handle 4 mounted on the cabinet door 3. Inside the cabinet body 1 are installed a shunt fuse group 5, a wiring harness mechanism 6, a controller 7, and a clamping mechanism 8. The clamping mechanism 8 includes a junction box 801, a mounting groove 802, a soft pad 803, a spring 804, a clamping block 805, a locking block 806, a spring 807, and a locking rod 808. The junction box 801 is located inside the cabinet body 1, the mounting groove 802 is formed on the junction box 801, the soft pad 803 is disposed on the inner wall of the mounting groove 802, the spring 804 is disposed within the mounting groove 802, and the clamping block 805 engages with the spring 806. The spring 804 is connected, the clamping block 806 is set on the clamping block 805, and the spring 807 and the clamping rod 808 are set on the junction box 801 and correspond to the clamping block 806. Through the cooperation of the spring 804 and the clamping block 805, a continuous and flexible clamping force is provided for the cable connector, which can effectively resist the loosening caused by vibration. The cooperation of the clamping block 806, the spring 807, and the clamping rod 808 constitutes a locking mechanism, which can prevent the clamping block from rebounding and failing under long-term vibration, and firmly lock the connector in place. The soft pad 803 not only increases the friction, but also plays a role in buffering and insulation, preventing the clamping block from directly scratching or excessively compressing the cable and connector.

[0024] Furthermore, the cable management mechanism 6 includes a slide rod 601, a slider 602, a connecting groove 603, and a cable management block 604. The slide rod 601 is connected to the inner wall of the cabinet 1. The slider 602 is slidably mounted on the slide rod 601. The connecting groove 603 is opened on the slider 602. The cable management block 604 is mounted on the slider 602 and corresponds to the connecting groove 603. The slider 602 can slide freely on the slide rod 601, allowing the cable management block 604 to be flexibly positioned according to the actual cable routing path, which is highly adaptable. The cable management block 604 and the connecting groove 603 can gather, concentrate, and fix the scattered cables in a specific position, making the layout inside the cabinet neat and orderly.

[0025] Furthermore, there are two displays 2, both installed on the upper part of the cabinet 1; setting up two displays 2 can simultaneously display different types of system parameters or status information without frequently switching interfaces.

[0026] Furthermore, there are multiple branch fuse groups 5, all installed inside the lower part of the cabinet 1; multiple branch fuses can provide independent overload and short circuit protection for different electrical circuits, preventing a single fault from paralyzing the entire system, and facilitating unified management and maintenance.

[0027] Furthermore, the controller 7 is installed inside the cabinet 1 and above the cable management mechanism 6; placing the controller 7 above the cable management mechanism 6 spatially separates it from components such as fuses that may generate heat or require frequent operation below, reducing mutual interference.

[0028] Furthermore, the soft pad 803 is made of rubber and is placed on the inner wall of the mounting groove 802; the rubber soft pad 803 can provide a higher coefficient of friction than metal or plastic, ensuring that the joint is not easy to slip, while its elasticity can absorb some vibration energy and buffer the clamping force to avoid damaging the joint.

[0029] Furthermore, one end of the spring piece 804 is connected to the inner wall of the mounting groove 802, and the other end is connected to the clamping block 805; this clarifies the connection method where one end of the spring piece 804 is fixed and the other end drives the clamping block 805, ensuring that the wall of the mounting groove 802 bears the reaction force, and that the elastic deformation of the spring piece 804 can be efficiently and directly converted into the clamping force of the clamping block.

[0030] The working principle of this utility is as follows: The operator holds the handle 4 to open the cabinet door 3, and passes multiple power cables and signal cables through the connecting slots 603 on the cable bundle block 604 of the cable bundle mechanism 6. The slider 602 is positioned on the slide rod 601 to group, straighten and fix the cables. The cable connector that needs to be connected to the junction box 801 is aligned with the mounting slot 802 of the clamping mechanism 8 and the connector is pushed into the mounting slot 802. The connector will squeeze the clamp 805, and the clamp 805 will compress the spring 804 to cause it to deform elastically. When the connector is inserted into place, the locking block 806 on the clamp 805 will be locked by the locking rod 808 under the action of the spring 807, thereby locking the clamp in the current position and ensuring that the connector is firmly clamped. After the external power supply is connected, the power is distributed to each circuit through the shunt fuse group 5. The controller 7 continuously receives signals from the sensors of the automatic vehicle and executes the predetermined control logic, and issues instructions to control the relevant equipment. The clamping mechanism 8 can effectively prevent the cable connector from loosening, and the cable bundling mechanism 6 can prevent the cables from getting tangled and worn due to shaking. When it is necessary to repair or replace the controller 7 or a certain line, the locking rod 808 is moved to release the locking block 806. The rebound force of the spring 804 will drive the clamp 805 to loosen, and the cable connector can be easily pulled out. Since the cable has been neatly fixed by the cable bundling mechanism 6, it is very convenient to track and identify specific cables, which is convenient for maintenance.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0032] The above description is only a preferred embodiment of the present utility model.
