[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] 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.

[0026] See Figure 1 As shown, a seat movable armrest rotation durability testing device includes a frame 1, within which a support assembly 2 and a rotating module 3 are arranged. The support assembly 2 has a set of workstations for loading seats, but is not limited to one set; more can be set according to actual needs. The number of rotating modules 3 is the same as the number of workstations, and they correspond one-to-one. Each rotating module 3 is connected to a power module 5 through a corresponding air pipe 4. During testing, the rotating modules 3 can drive the movable armrest of the seat to open, close, and rotate under the control of the power module 5. The device also includes a control system 6, with the power module 5 electrically connected to the control system 6, which can control the power module 5.

[0027] Further details can be found by referring to [link / reference]. Figure 1As shown, in this embodiment, the support assembly 2 includes a base 21 and a support 22. During installation, the base 21 is fixed to the inner bottom surface of the frame 1 via a connecting foot 23, and the support 22 is disposed on the base 21. During testing, the seat is fixed on the support 22. Therefore, in this embodiment, the number of workstations is equal to the number of sets of supports 22. It should be noted that in this embodiment, the connecting foot 23 enables the base 2 to be detachably fixed, thereby allowing the support assembly 2 to be replaced and adjusted. This allows for the testing of seats of different specifications and models, thus improving the applicability of the device. Secondly, see... Figure 3 As shown, the base 21 uses a pair of parallel aluminum profiles, and the connecting foot 23 has an L-shaped cross-section. Locking holes 231 are respectively provided on its horizontal and vertical connecting plates. The locking holes 231 are all elongated holes. Through the combination of horizontal and vertical elongated holes, the base 21 can be finely adjusted in two dimensions (X / Y direction) in the spatial coordinate system. This allows for fine-tuning of the position of different specifications and models of seats when they are first fixed. This avoids the connection between the movable armrest of the seat and the rotating module 3 being affected by misalignment, while improving the connection accuracy between the two. This improves the seat installation efficiency and the detection accuracy.

[0028] Further, see Figure 5 As shown, in this embodiment, the rotating module 3 includes a tooling fixture 31, an actuating cylinder 32, and a connecting seat 33; the tooling fixture 31 and the piston rod of the actuating cylinder 32 are hinged together by corresponding hinge seats 34; the rear end of the actuating cylinder 32 body is hinged to the connecting seat 33 by corresponding hinge seats 34; during installation, the tooling fixture 31 is connected to the movable armrest of the seat to be tested, the connecting seat 33 is connected to the frame 1, and the actuating cylinder 32 is connected to the power module 5 through the air pipe 4; during testing, the power module 5 controls the extension and retraction of the piston rod of the actuating cylinder 32 to drive the movable armrest of the seat to open and close rotationally; wherein, in this embodiment, see Figure 1 As shown, the power module 5 includes an air compressor 51 and a solenoid valve 52. During installation, the solenoid valve 52 is connected to the air compressor 51 through the corresponding air pipe 4. At the same time, both the air compressor 51 and the solenoid valve 52 are electrically connected to the control system 6. Meanwhile, the actuator cylinder 32 is connected to the solenoid valve 52 through the air pipe 4. During detection, the air compressor 51 provides an air source, and the solenoid valve 52 changes the direction of the air source flow, thereby controlling the extension and retraction of the piston rod of the actuator cylinder 32.

[0029] In this embodiment, see Figure 2As shown, the tooling fixture 31 includes a connecting plate 311, a U-bolt 312, and a nut 313 connected to the U-bolt 312. During installation, the connecting plate 311 is set at the upper end of the movable armrest of the seat. After the U-bolt 312 wraps around the movable armrest of the seat, its upper end passes through the connecting plate 311 and is then locked into the nut 313. The number of sets of U-bolts 312 is only one implementation method and is not intended to limit the scope of this application. In actual installation, more sets can be used.

[0030] Or see Figure 4 As shown, the tooling fixture 31 includes a pair of connecting plates 311, a pair of bolts 314, and nuts 313 connected to the bolts 314. During installation, after the pair of connecting plates 311 are respectively positioned at the upper and lower ends of the movable armrest of the seat, the pair of bolts 314 pass through the pair of connecting plates 311 and are locked into the nuts 313. The number of sets of bolts 314 is only one implementation method and is not intended to limit the scope of this application. In actual installation, more bolts can be set.

[0031] Further, see Figure 5 As shown, in this embodiment, magnetic switches 7 are respectively provided on the actuator cylinder 32. The magnetic switches 7 are electrically connected to the control system 6. The maximum retraction length of the piston rod of the actuator cylinder 32 is controlled by the magnetic switches 7, thereby controlling the maximum opening angle of the movable armrest of the seat, thus avoiding damage to the movable armrest of the seat due to excessive opening angle.

[0032] Furthermore, in this embodiment, the control system 6 includes an electrical control box and an upper-level operating system; during detection, the upper-level operating system is used to set the single detection time and the number of detections; it should be noted that, in this embodiment, the rotation angle of the movable armrest of the seat is adjusted by setting the time.

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

[0034] During testing, the seat is first installed on the workstation, i.e., on the support 22. At this time, the movable armrests of the seat are in the initial state, i.e., in a horizontal state, while the piston rod of the actuator cylinder 32 is in the extended state. Then, the device is powered on, and after powering on, the time and number of tests are set through the upper-level operating system according to the testing requirements. After the settings are completed, the device is started. At this time, the air compressor 51 starts, the solenoid valve 52 is energized and opens, and the air source enters the actuator cylinder 32. The piston rod of the actuator cylinder 32 retracts, driving the movable armrests of the seat to rotate upward around the axis to the set angle. Then, the solenoid valve 52 is de-energized, changing the air source flow direction. The piston rod of the actuator cylinder 32 extends, driving the movable armrests of the seat to rotate downward around the axis to reset to the horizontal position, completing one cycle. The above actions are repeated until the set number of tests is completed.

[0035] 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.
