Description

Technical Field

[0001] This utility model relates to the field of EMU commissioning technology, and in particular to a commissioning device for EMUs with a flip-over protective mechanism. Background Technology

[0002] EMU, also known as "EMU train", is a type of modern train consisting of several powered cars (EMU cars) and unpowered cars (trailer cars). The train operates in a fixed formation during its normal service life. During routine maintenance, EMU trains need to be tested on individual cars or the entire train, which requires testing personnel to perform the tests.

[0003] Currently, the debugging equipment on the market uses multiple buttons on the control panel to test whether the various functions of the EMU are operating normally. However, the buttons on the control panel are directly exposed, and the surface of the buttons is prone to accumulating impurities and dust. At the same time, long-term exposure can easily cause accidental touches and accelerate wear. Utility Model Content

[0004] This utility model discloses a flip-up protective debugging device for high-speed trains, which aims to solve the technical problem that the operation buttons of existing high-speed train debugging devices are prone to dust accumulation and accidental touch and wear due to exposure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flip-up protective debugging device for high-speed trains includes a tooling housing. A protective mechanism is rotatably mounted on one outer wall of the tooling housing. The protective mechanism includes a protective cover, and an installation opening is provided on one outer wall of the protective cover. A locking component is installed on the inner wall of the installation opening. A connecting groove matching the locking component is provided on one outer wall of the tooling housing. Symmetrically arranged limiting grooves are provided on both inner walls of the connecting groove. Two symmetrically arranged magnetic strips are embedded on one outer wall of the protective cover.

[0007] In a preferred embodiment, a partition frame is fixedly connected to the inner wall of the protective cover, and a handle is fixedly connected to one outer wall of the protective cover.

[0008] In a preferred embodiment, the protective mechanism further includes two mounting bases fixedly connected to the tooling housing, and the protective cover is rotatably connected to the two mounting bases.

[0009] In a preferred embodiment, the locking assembly includes a connecting box fixedly connected to the inner wall of the mounting port, and both outer walls of the connecting box are provided with round openings. The inner walls of the two round openings are slidably connected with limit pins. The specifications of the limit pins match the specifications of the limit grooves. Connecting rods are fixedly connected to the outer walls of the opposite sides of the two limit pins.

[0010] In a preferred embodiment, the top outer wall of the connecting box has an opening, and a T-shaped block is slidably connected to the inner wall of the opening. A trapezoidal block is fixedly connected to the bottom outer wall of the T-shaped block, and grooves are formed on both sides of the outer wall of the trapezoidal block. The two connecting rods are slidably connected to the inner walls of the two grooves respectively. Two symmetrically arranged mounting rods are fixedly connected to the inner wall of the connecting box, and springs are sleeved on the outer walls of the two mounting rods. The T-shaped block is slidably connected to the outer walls of the two mounting rods. A detachable cover plate is installed on one side of the outer wall of the connecting box, and a rubber pad is fixedly connected to the bottom outer wall of the connecting box.

[0011] In a preferred embodiment, a plurality of buttons are installed on one side of the outer wall of the tooling housing, and a plurality of heat dissipation holes are provided on both sides of the outer wall of the tooling housing.

[0012] In a preferred embodiment, a connector is installed on one outer wall of the tooling housing, and a handle is installed on the top outer wall of the tooling housing. Protective pads are fixedly connected to each of the eight corners of the tooling housing.

[0013] As can be seen from the above, the flip-up protective EMU debugging equipment provided by this utility model improves the protective performance of the EMU debugging equipment. The flip-up protective cover facilitates the protection of the buttons on the tooling shell. The protective cover effectively prevents dust from falling on the buttons and also effectively prevents wear on the button surface caused by accidental touch or external force contact, thus achieving the technical effect of flip-up protective buttons in the debugging equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The present invention discloses a flip-up protective debugging device for high-speed trains, which is mainly used in scenarios where it is inconvenient to protect the control panel of existing devices.

[0022] Reference Figures 1-5 A rotatable protective debugging device for high-speed trains includes a tooling housing 1. A protective mechanism 2 is rotatably mounted on one outer wall of the tooling housing 1. The protective mechanism 2 includes a protective cover 9, and an installation opening is provided on one outer wall of the protective cover 9. A locking component 12 is installed on the inner wall of the installation opening. A connecting groove 8 matching the locking component 12 is provided on one outer wall of the tooling housing 1. A symmetrically arranged limiting groove is provided on both inner walls of the connecting groove 8. Two symmetrically arranged magnetic strips 14 are embedded on one outer wall of the protective cover 9. A partition frame 10 is fixedly connected to the inner wall of the protective cover 9. A handle 11 is fixedly connected to one outer wall of the protective cover 9. The protective mechanism 2 also includes two mounting seats 13 fixedly connected to the tooling housing 1. The protective cover 9 is rotatably connected to the two mounting seats 13.

[0023] The protective mechanism 2 provided on the tooling housing 1 facilitates the protection of the operating panel on the debugging equipment. The protective cover 9 is rotatably mounted on the tooling housing 1. When the protective cover 9 is rotated to its maximum angle, the partition frame 10 divides the interior of the protective cover 9 into multiple areas, which facilitates the temporary placement of small tools during the debugging process. At the same time, it improves the structural strength of the protective cover 9 and prevents it from being deformed under pressure. The handle 11 facilitates the opening and closing of the protective cover 9 and also provides support when the protective cover 9 is flat. The cooperation between the locking component 12 and the magnetic strip 14 facilitates locking the protective cover 9 onto the tooling housing 1. The magnetic strip 14 is attracted to the tooling housing 1, which enhances the stability of the protective cover 9 when it is closed and helps to prevent dust.

[0024] Reference Figure 3-5In a preferred embodiment, the locking assembly 12 includes a connecting box 15 fixedly connected to the inner wall of the mounting opening. Both outer walls of the connecting box 15 have circular openings, and the inner walls of both circular openings are slidably connected to limit pins 19. The specifications of the limit pins 19 match the specifications of the limit grooves. Connecting rods 24 are fixedly connected to the outer walls of opposite sides of the two limit pins 19. The top outer wall of the connecting box 15 has an opening, and the inner wall of the opening is slidably connected to a T-shaped block 17. The bottom outer wall of the T-shaped block 17 is fixed... A trapezoidal block 20 is connected, and grooves 23 are provided on both outer walls of the trapezoidal block 20. Two connecting rods 24 are slidably connected to the inner walls of the two grooves 23 respectively. Two symmetrically arranged mounting rods 18 are fixedly connected to the inner wall of the connecting box 15, and springs 22 are sleeved on the outer walls of the two mounting rods 18. A T-shaped block 17 is slidably connected to the outer walls of the two mounting rods 18. A detachable cover plate 16 is installed on one outer wall of the connecting box 15, and a rubber pad 21 is fixedly connected to the bottom outer wall of the connecting box 15.

[0025] When the protective cover 9 is opened, press the T-block 17. When the T-block 17 is pressed, it compresses the springs 22 on the two mounting rods 18, thereby moving the trapezoidal block 20. When the trapezoidal block 20 moves, the connecting rod 24 slides on the slide groove 23. Since the side of the trapezoidal block 20 has a structure that is narrower at the top and wider at the bottom, it drives the two connecting rods 24 to move towards each other, thereby causing the two limit pins 19 to move towards each other and disengage from the limit groove. At this time, the connecting box 15 can be pulled out from the connecting groove 8, thereby opening the protective cover 9. The rubber pad 21 can effectively reduce the wear between the connecting box 15 and the connecting groove 8. The removable cover plate 16 facilitates the maintenance of the parts in the connecting box 15 in the future.

[0026] Reference Figure 1-2 In a preferred embodiment, a plurality of buttons 7 are installed on one side of the outer wall of the tool housing 1, a plurality of heat dissipation holes 3 are provided on both sides of the outer wall of the tool housing 1, a connector 4 is installed on one side of the outer wall of the tool housing 1, and a handle 6 is installed on the top outer wall of the tool housing 1. Protective pads 5 are fixedly connected to each of the eight corners of the tool housing 1.

[0027] Multiple buttons 7 on the tool housing 1 facilitate the testing of different functions in the EMU. When the debugging equipment is working, it generates heat inside. The heat dissipation holes 3 help the debugging equipment dissipate heat. The connector 4 connects the debugging equipment to the EMU via a cable. The handle 6 improves the portability of the debugging equipment. The protective pad 5 helps to protect the debugging equipment.

[0028] Working principle: When in use, first connect connector 4 to the EMU via cable, then open the protective cover 9. When opening the protective cover 9, press the T-block 17 first. When the T-block 17 is pressed, it compresses the springs 22 on the two mounting rods 18, thereby driving the trapezoidal block 20 to move. When the trapezoidal block 20 moves, the connecting rod 24 slides on the slide groove 23. Since the side of the trapezoidal block 20 has a structure that is narrower at the top and wider at the bottom, it drives the two connecting rods 24 to move towards each other, thereby causing the two limit pins 19 to move towards each other and disengage from the limit groove. At this time, the connecting box 15 can be pulled out from the connecting groove 8, so that the protective cover 9 can be rotated to expose the button 7. Different functions can be activated by different buttons 7 to test the EMU. The partition frame 10 inside the protective cover 9 forms multiple areas, which can be used to classify and store small tools during debugging.

[0029] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
