[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0025] See Figure 1-3 As shown (labeled A in the figure represents the seat under test), a load-bearing durability testing device for the armrest of a high-speed train seat includes a test frame 1. The test frame 1 has a workstation for loading the seat under test. The workstation is equipped with a loading mechanism 2 for performing load-bearing durability testing on the armrest of the seat under test. The loading mechanism 2 is fixed on the test frame 1 and connected to a power module 3. During testing, the loading mechanism 2 performs load-bearing durability testing on the armrest of the seat under test through the drive of the power module 3. The device also includes a control system 4 for controlling the device. The loading mechanism 2 and the power module 3 are electrically connected to the control system 4.

[0026] Furthermore, the test frame 1 adopts a frame structure, which is constructed from metal profiles, preferably stainless steel and aluminum alloy profiles.

[0027] Furthermore, the loading mechanism 2 includes a transfer frame 21, a loading component 22, and a clamping component 23. The transfer frame 21 also adopts a frame structure, constructed from metal profiles, and its material is the same as that of the test frame 1. During installation, the transfer frame 21 is connected to the test frame 1. It should be noted that the "connection" here can be a non-removable fixed connection (e.g., welding) or a detachable fixed connection (e.g., locking with bolts). In this embodiment, the transfer frame 21 is detachably fixed to the test frame 1. The loading component 22 is fixed to the transfer frame 21, and the loading component 22 is inclined on the transfer frame 21. In this embodiment, the inclination angle is preferably 45°. The clamping component 23 is connected to the armrest of the seat under test. During testing, the loading component 22 loads the clamping component 23 to perform a load-bearing durability test on the armrest of the seat under test.

[0028] Furthermore, the loading assembly 22 includes a mounting base plate 221, on which a cylinder 222 is mounted. The cylinder 222 is a guide rod cylinder, and a force sensor 223 is mounted at the front end of the output end of the cylinder 222. An extension rod 224 is mounted at the front end of the force sensor 223. During installation, the cylinder 222 is tilted and fixed to the adapter frame 21 via the mounting base plate 221, and the force sensor 223 is electrically connected to the control system 4. During testing, driven by the cylinder 222, the front end of the extension rod 224 acts on the clamp assembly 23, thereby loading the clamp assembly 23 and performing a load-bearing durability test on the armrest of the seat under test. During the loading process, the force sensor 223 monitors the loading force and feeds back the monitoring data to the control system 4 in real time.

[0029] Furthermore, a magnetic switch 225 is provided on the outer surface of the cylinder 222, and the magnetic switch 225 is electrically connected to the control system 4; during testing, the number of times the cylinder 222 is operated is counted through the magnetic switch 225.

[0030] Furthermore, the clamp assembly 23 includes an upper clamping plate 231, a lower clamping plate 232, and bolts 233. During installation, the upper clamping plate 231 is positioned on the upper surface of the armrest of the seat being tested, and the lower clamping plate 232 is positioned on the lower surface of the armrest. After the upper clamping plate 231 and the lower clamping plate 232 are installed, they are locked to the armrest of the seat being tested using the bolts 233. In this embodiment, the upper end of the upper clamping plate 231 is a stepped surface, which includes a bottom surface and a... The upper end face, the lower bottom face, and the upper end face are connected together by an inclined surface. During testing, the front end of the extension rod 224 acts on the inclined surface of the upper clamping plate 231, thereby loading the clamping assembly 23 and thus performing a load-bearing durability test on the armrest of the seat under test. It should be noted that, in this embodiment, after the clamping assembly 23 is connected to the armrest of the seat under test, it is necessary to ensure that the loading position of the extension rod 224 on the inclined surface of the upper clamping plate 231 is approximately 60mm away from the front edge of the armrest of the seat under test.

[0031] Furthermore, the power module 3 includes an air compressor 31 and a solenoid valve 32. During installation, the cylinder 222 is connected to the air compressor 31 through a corresponding air pipe, and the solenoid valve 32 is connected to the corresponding air pipe. The air compressor 31 and the solenoid valve 32 are respectively connected to the control system 4. During testing, the control system 4 controls the air compressor 31 to start while controlling the on / off state of the solenoid valve 32 to adjust the flow direction, gas flow rate, and pressure of the air source. This allows the control of the extension and retraction of the cylinder 222, as well as the control of the movement speed and force of the cylinder 222.

[0032] Furthermore, the control system 4 includes an electrical control box 41 and an upper-level operating system 42, with the upper-level operating system 42 positioned above the electrical control box 41; wherein, in this embodiment, the electrical control box 41 is provided with a start button 411, a stop button 412, and an emergency stop switch 413.

[0033] The working principle of this utility model is as follows:

[0034] When testing the seat armrests, first load the seat into the workstation within the test rack 1; then press the start button 411 to power on the device, and enter the upper-level operating system 42 interface. Set the test load, test frequency, and number of tests according to the requirements and interface prompts (in this embodiment, the load is 600N, the test frequency is 20 times / min, and the number of tests is 2×10). 4After completing all settings, click the start / stop icon in the operation interface of the upper-level operating system 42 to start the device. At this time, the upper-level operating system 42 controls the cylinder 222 to run according to the set load, test frequency and test number to test the seat armrest.

[0035] During the test, the control system 4 receives the electrical signal of the force sensed by the force sensor 223 in real time. When the load and loading time reach the set values, the control system 4 controls the opening / closing of the solenoid valve 32 to adjust the flow of the air source, thereby controlling the cylinder 222 to perform reciprocating operation. During the cyclic operation of the cylinder 222, the magnetic switch 225 counts and feeds back to the control system 4. When the set number of times is reached, the control system 4 stops the device.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
