Description

Technical Field

[0001] This utility model belongs to the field of tabletop testing technology, specifically, it relates to a durability testing device for a built-in tabletop for high-speed train seats. Background Technology

[0002] Built-in tray tables are a common design feature in seats, especially in airplanes, trains, long-distance buses, and some high-end business vehicles and office chairs. To ensure that the finished built-in tray tables meet quality and reliability requirements, they need to undergo durability testing.

[0003] Traditional durability testing methods for built-in tabletops mainly fall into two categories. The first relies on prolonged real-world use. This method requires significant time and manpower, resulting in a lengthy testing cycle and a substantial increase in the time cost from product development to market launch. Furthermore, the diversity of usage environments and user operating habits during actual use makes it difficult to guarantee the uniformity and accuracy of testing conditions, thus affecting the reliability of the test results. The second method uses robotic arms to complete the test. Robotic arm equipment is typically expensive, with high purchase and maintenance costs, which can impose a significant financial burden on some companies. Utility Model Content

[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 As shown, a durability testing device for built-in tabletops in train seats includes a support frame 1, which comprises a base 11 and a mounting frame 12, both of which are constructed from aluminum profiles. A set of workstations for fixing the seat under test is formed on the base 11, but not limited to one set; more can be provided depending on actual needs. The mounting frame 12 is mounted on the base 11 and has a flipping mechanism 2 corresponding to each workstation. The flipping mechanism 2 allows the built-in tabletop of the seat under test to be unfolded and folded. A control module 3 is located on one side of the support frame 1. The control module 3 allows setting the operating speed of the flipping mechanism 2, the interval time between each action, and the number of cycles, while also controlling the start and stop of the flipping mechanism 2.

[0026] Further, see Figure 2 As shown, in this embodiment, the flipping mechanism 2 includes a flipping module A21 and a flipping module B22. The flipping module A21 and the flipping module B22 are connected together by a first connecting plate 23. The flipping module A21 can drive the flipping module B22 to rotate through the first connecting plate 23.

[0027] In this embodiment, see Figure 1-2As shown, the flipping module A21 includes a rotary cylinder A211 and a fixing plate 212. During installation, the rotary cylinder A211 is fixed to one end of the fixing plate 212, while the other end of the fixing plate 212 is fixed to the mounting bracket 12 by corresponding locking bolts and nuts. In this embodiment, the hole through which the locking bolt passes in the fixing plate 212 is an elongated hole, which facilitates the adjustment of the installation position of the rotary cylinder A211.

[0028] See also Figure 2-3 As shown, the flipping module B22 includes a rotary cylinder B221, a connecting seat 222, and a second connecting plate 223. During installation, the connecting seat 222 is mounted on the turntable of the rotary cylinder B221. One end of the second connecting plate 223 is connected to the connecting seat 222 via corresponding locking bolts and nuts, and the other end of the second connecting plate 223 is also connected to the built-in table of the seat under test via corresponding locking bolts and nuts. In this embodiment, the locking bolts located at the end where the second connecting plate 223 and the connecting seat 222 are connected pass through a hole in the second connecting plate 223, which is an elongated hole to facilitate the connection between the second connecting plate 223 and the connecting seat 222.

[0029] Further, see Figure 1 As shown, in this embodiment, the control module 3 includes an air supply unit 31 and a control system 32, and the air supply unit 31 is electrically connected to the control system 32.

[0030] See also Figure 1 As shown, the air supply unit 31 includes an air pump 311 and two sets of solenoid valves 312. During installation, the air pump 311 is connected to the rotary cylinder A211 and the rotary cylinder B221 respectively through corresponding air pipes, and provides air source for the rotary cylinder A211 and the rotary cylinder B221 through the air pump 311. The solenoid valves 312 are respectively installed in the air pipes connecting the air pump 311 to the rotary cylinders A211 and B221, and the solenoid valves 312 are electrically connected to the control system 32. During testing, the control system 32 controls the solenoid valves 312, thereby controlling the air flow direction, flow rate and on / off state of the air source in the air pipes connecting the air pump 311 to the rotary cylinders A211 and B221.

[0031] For further details, please refer to [link / reference]. Figure 1As shown in the figure, in this embodiment, the control system 32 includes an electrical control box 321 and a host computer operating system 322. The electrical control box 321 is equipped with a start button, a stop button and an emergency stop switch, while the host computer operating system 322 is located above the electrical control box 321. The host computer operating system 322 is used to set the running speed, the interval time of each action and the number of cycles.

[0032] The working principle of this utility model is as follows:

[0033] See Figure 3-4 As shown (A in the figure represents the seat; B in the figure represents the device), when performing a durability test on the table built into the seat, first, the seat to be tested is loaded onto the corresponding test station, and then the other end of the second connecting plate 223 is connected to the table built into the seat. At this time, the table is in the seat-folded state, which is the initial test position. After powering on the device, the host computer operating system 322 is accessed, and the corresponding running speed, interval time of each action, and number of cycles are set according to the requirements and prompts on the operating interface. Then, the device is started. At this time, see... Figure 5 As shown, the rotary cylinder A211 drives the tilting module B to rotate via the first connecting plate, thereby causing the table to rotate out of the seat and into position (as shown). Figure 4 As shown), the rotary cylinder B221 drives the table to rotate from a vertical state to a horizontal state via the connecting seat 222 and the second connecting plate 223 (as shown). Figure 3 (As shown), then the rotary cylinder B221 reverses, causing the table to rotate from a horizontal state to a vertical state. After it reaches the position, the rotary cylinder A211 reverses, causing the table to rotate back to the initial position, completing one cycle. Repeat the above actions until the test is completed.

[0034] 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.
