A mounting plate is provided on the common surface of the connection port and the main board cavity. The surface of the mounting plate is provided with connection terminals, all of which are electrically connected to the main control board.

[0004] In the above solution, the damping position is maintained by designing the device to match the size of the output interface female connector and relying on the size matching of the plug part. This results in the following disadvantages: when using the device, the connection method is simple and the damping position is maintained only by the size matching. Utility Model Content

[0005] The purpose of this invention is to provide an aviation power vehicle starting performance testing device to solve the problem that the device has a single connection method and relies solely on size matching to maintain the damping position during use.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an aviation power vehicle starting performance testing device, including a protective plate, the protective plate being detachably disposed inside a housing, a connection port being provided on the right side of the housing, a mounting plate being bolted to the inside of the connection port, several output interfaces being fixed to the front side of the mounting plate, several connection terminals being fixed to the front side of the mounting plate, threaded holes being provided on the top and bottom surfaces of the housing, screws being threadedly connected to two of the threaded holes, rotating plates being fixed to the outer ends of the two screws, an upper arc-shaped clamping plate being movably disposed inside the connection port, a lower arc-shaped clamping plate being movably disposed inside the connection port, rotating grooves being provided on the top surface of the upper arc-shaped clamping plate and the bottom surface of the lower arc-shaped clamping plate, rotating blocks being fixed to the threaded ends of the two screws, and the two rotating blocks being rotatably disposed in the two rotating grooves.

[0007] Preferably, anti-slip pads are fixed inside the upper arc-shaped clamping plate and the lower arc-shaped clamping plate, and the anti-slip pads are provided with anti-slip patterns. The main control board is connected to the inside of the outer shell by bolts. The main control board is electrically connected to the connecting terminal.

[0008] Preferably, the top and bottom surfaces of the outer shell are respectively provided with limiting holes, and the top surface of the upper arc-shaped clamping plate and the bottom surface of the lower arc-shaped clamping plate are respectively fixed with limiting posts, and the two limiting posts are slidably inserted into the two limiting holes.

[0009] Preferably, the protective plate has a fixing groove on its front and rear sides, and the outer wall of the outer shell has a fixing hole on its front and rear sides. A fixing post is slidably inserted into each of the two fixing holes. The two fixing posts are slidably inserted into the two fixing grooves.

[0012] Compared with existing technologies, the aviation power vehicle starting performance testing equipment that adopts the above technical solution has the following beneficial effects:

[0013] 1. In use, the protective plate, connecting port, mounting plate, output interface, threaded hole, screw, rotating plate, upper arc-shaped clamping plate, lower arc-shaped clamping plate, rotating groove and rotating block work together to help the operator to firmly abut the outer shell against the interface of the female seat after initially holding it through the damping position.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4As shown, an aviation power vehicle starting performance testing device includes a protective plate 1, which is detachably installed inside a housing 2. A connection port 3 is provided on the right side of the housing 2. A mounting plate 4 is bolted to the inside of the connection port 3. Several output interfaces 5 are fixed to the front side of the mounting plate 4, and several connection terminals are fixed to the front side of the mounting plate 4. Threaded holes 6 are provided on the top and bottom surfaces of the housing 2. Screws 7 are threaded into the two threaded holes 6, and rotating plates 8 are fixed to the outer ends of the two screws 7. An upper arc-shaped clamping plate 9 and a lower arc-shaped clamping plate 10 are movably installed inside the connection port 3. Rotating grooves 11 are provided on the top surface of the upper arc-shaped clamping plate 9 and the bottom surface of the lower arc-shaped clamping plate 10, respectively. Rotating blocks 12 are fixed to the threaded ends of the two screws 7, and the two rotating blocks 12 are rotatably installed in the two rotating grooves 11.

[0023] In use, the staff first installs the protective plate 1 inside the outer shell 2. The design of the protective plate 1 can provide reliable protection for the components inside the outer shell 2, avoiding damage caused by external factors. The right side of the outer shell 2 is provided with a connection port 3. The connection port 3 and its internal output interface 5 are matched with the size of the power supply car seat. When the staff needs to connect the outer shell 2 to the power supply car seat, they only need to smoothly insert the output interface 5 into the corresponding interface of the seat. Relying on the size matching design, the damping position is maintained. Then, the staff rotates the two rotating plates 8 on the top and bottom surfaces of the outer shell 2 respectively. The rotation of the rotating plates 8 drives the screw 7 to rotate synchronously. The threaded end of the screw 7 is fixed with a rotating block 12. The rotating block 12 can rotate freely in the rotating groove 11. As the screw 7 rotates, the upper arc-shaped clamp 9 and the lower arc-shaped clamp 10 approach each other inside the connection port 3, and finally tightly abut against the interface of the seat, further enhancing the connection strength between the outer shell 2 and the seat. The combined use of the protective plate 1, connecting port 3, mounting plate 4, output interface 5, threaded hole 6, screw 7, rotating plate 8, upper arc-shaped clamping plate 9, lower arc-shaped clamping plate 10, rotating groove 11, and rotating block 12 allows the operator to firmly secure the outer shell 2 against the interface of the female seat after it has been initially held in the damped position. This dual fixing method improves the connection stability between the outer shell 2 and the female seat, effectively preventing loosening and detachment caused by external forces, thus preventing interruptions during the test and ensuring the smooth progress of the test.

[0024] like Figures 1-4 As shown, anti-slip pads 13 are fixed inside the upper arc-shaped clamping plate 9 and the lower arc-shaped clamping plate 10 respectively. Anti-slip textures 14 are provided on the anti-slip pads 13. The main control board 15 is connected to the inside of the outer shell 2 by bolts. The main control board 15 is electrically connected to the connection terminal. The TFT display module 16 is connected to the inside of the outer shell 2 by bolts. The TFT display module 16 is electrically connected to the main control board 15.

[0025] During use, when the upper arc-shaped clamp 9 and the lower arc-shaped clamp 10 clamp the interface of the power supply vehicle female connector, the anti-slip pad 13 fixed inside them will make close contact with the interface of the female connector. The anti-slip pad 13 has anti-slip texture 14, which can further increase friction and ensure a more stable clamping. During the test, when the operator inserts the connection terminal into the aircraft end, the terminal will be short-circuited on the aircraft. After rigorous testing by the overvoltage and overcurrent protection circuit and the reverse connection protection circuit, the main control board 15 adopts the DC-DC+LDO power supply method. This power supply method maintains high power efficiency and provides good ripple suppression for the subsequent digital circuits, ensuring the stable operation of the circuit. At the same time, the TFT display module 16 communicates with the main control board 15 through the SPI interface. The TFT display module 16 can display test data and status information in real time, realizing efficient human-machine interaction and making it convenient for operators to understand the test status at any time. The design of the anti-slip pad 13 and anti-slip texture 14 increases the clamping friction of the upper arc-shaped clamping plate 9 and the lower arc-shaped clamping plate 10 on the female interface, improves the anti-slip performance, and further enhances the stability of the connection.

[0026] like Figures 1-4 As shown, the top and bottom surfaces of the outer shell 2 are respectively provided with limiting holes 17. The top surface of the upper arc-shaped clamping plate 9 and the bottom surface of the lower arc-shaped clamping plate 10 are respectively fixed with limiting posts 18. The two limiting posts 18 are slidably inserted into the two limiting holes 17. The front and rear sides of the protective plate 1 are respectively provided with fixing grooves 19. The front and rear sides of the outer wall of the outer shell 2 are respectively provided with fixing holes 20. The two fixing holes 20 are respectively slidably inserted with fixing posts 21. The two fixing posts 21 are respectively slidably inserted into the two fixing grooves 19. The outer ends of the two fixing posts 21 are respectively fixed with blocks 22. The two blocks 22 and the outer shell 2 are respectively fixed with springs 23. The two springs 23 are respectively wrapped around the two fixing posts 21.

[0027] During use, when the upper arc-shaped clamping plate 9 and the lower arc-shaped clamping plate 10 move up and down through the screw 7, the limiting post 18 slides into the limiting hole 17, which can limit the upper arc-shaped clamping plate 9 and the lower arc-shaped clamping plate 10, ensuring that they will not deviate or shake, and ensuring that the clamping plate can accurately abut against the interface of the female seat, avoiding connection instability caused by clamping plate deviation or shaking, thereby further improving the connection reliability between the outer shell 2 and the female seat. When the staff needs to install the protective plate 1 inside the outer shell 2, they first pull the two blocks 22 outwards. At this time, the fixing post 21 fixed on the block 22 will move accordingly and stretch the spring 23. Then, the protective plate 1 is placed inside the outer shell 2. When the fixing groove 19 is aligned with the fixing hole 20, the block 22 is released. Under the elastic force of the spring 23, the fixing post 21 will automatically reset and insert into the fixing groove 19, thus completing the fixed installation of the protective plate 1. Conversely, when the protective plate 1 needs to be removed, the staff only needs to pull the two blocks 22 outwards again to disengage the fixing post 21 from the fixing groove 19, and the protective plate 1 can be easily removed from the outer shell 2. This allows the staff to conveniently and quickly install and remove the protective plate 1 without using complicated tools or cumbersome steps, thus improving work efficiency.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the inner wall of the outer shell 2 has grooves 24 on the left and right sides respectively, and the protective plate 1 has sliders 25 fixed on the left and right sides respectively. The two sliders 25 are slidably arranged in the two grooves 24 respectively. The bottom surface of the two sliders 25 is fixed with a first magnet 26 respectively, and the bottom surface of the inner surface of the two grooves 24 is fixed with a second magnet 27 respectively. The two second magnets 27 are magnetically attracted to the two first magnets 26 respectively.

[0029] In use, when the operator installs the protective plate 1 inside the outer casing 2, firstly, align the sliders 25 fixed on the left and right sides of the protective plate 1 with the sliding grooves 24 on the left and right sides of the inner wall of the outer casing 2. Then, smoothly place the protective plate 1 inside the outer casing 2, allowing the sliders 25 to slide along the sliding grooves 24. The cooperation between the sliders 25 and the sliding grooves 24 provides precise positioning for the protective plate 1, preventing it from shifting during installation and improving the accuracy of the installation process. After the operator installs the protective plate 1 inside the outer casing 2 and slides the sliders 25 into the sliding grooves 24, the first magnet 26 fixed on the bottom surface of the slider 25 will magnetically attract the second magnet 27 fixed on the bottom surface inside the sliding grooves 24. This magnetic attraction further secures the sliders 25, thereby enhancing the stability of the protective plate 1 and providing additional fixing force.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
