Description

Technical Field

[0001] This utility model relates to the technical field of high-speed train seat components, specifically a table for placing high-speed train seats. Background Technology

[0002] The tray table for high-speed train seats is a small tray table on the high-speed train seats used to place items or meals.

[0003] For example, Chinese patent CN218640850U discloses a folding table for high-speed trains, including a seat. The frame can rotate around a first rotating rod, allowing it to rotate out from the top groove. Passengers can place mobile phones, tablets, books, etc. on the frame for convenient use and improved functionality. After the frame angle is adjusted, a limiting rod rotates around a second rotating rod at a certain angle, allowing the limiting rod to work with a limiting seat to support the frame, thereby improving its stability. A support rod rotates around a third rotating rod at a certain angle, making it perpendicular to the table. A sliding rod can slide within an inner groove, allowing the overall length of the support rod to be adjusted. This allows the sliding rod to rest on the train floor. The combined action of the support rod and the sliding rod provides support for the table, improving its stability and load-bearing capacity.

[0004] Existing high-speed train seat tables suffer from poor stability and wobbling due to single-point support after unfolding, as well as insufficient load-bearing capacity. Furthermore, the single-axis support of traditional high-speed train seat tables leads to excessive aging at the connection points, affecting their service life. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to Figures 1 to 5 The present invention provides the following technical solution: A table for a high-speed train seat includes a mounting component 1 installed at the bottom rear side of the high-speed train seat. Two mounting components 1 are provided and symmetrically installed at the bottom rear side of the high-speed train seat. Each mounting component 1 is equipped with a support assembly, and the table body 2 is mounted on the mounting component 1 through the support assembly. The support assembly includes a main support rod 3 rotatably connected to the lower end of the mounting component 1, and the end of the main support rod 3 away from the mounting component 1 is rotatably connected to the bottom of the table body 2. A connecting rod 4 is rotatably connected to the upper end of the mounting component 1, and a secondary support rod 5 is rotatably connected to the bottom of the table body 2.

[0019] The lower end of the mounting component 1 is fixedly connected to the mounting shaft 6, and the lower end of the main support rod 3 is rotatably connected to the outside of the mounting shaft 6. The upper end of the mounting component 1 is provided with a mounting hole 7, and the lower end of the connecting rod 4 is rotatably connected to the inside of the mounting hole 7. The upper end of the main support rod 3 is provided with a first sliding groove 8, and the end of the connecting rod 4 away from the mounting component 1 and the side close to the main support rod 3 is fixedly connected to a first sliding rod 9, and the first sliding rod 9 is slidably connected to the inside of the first sliding groove 8. The mounting component 1, the main support rod 3 and the connecting rod 4 form a triangular structure.

[0020] The main support rod 3 has a second sliding groove 10 in the middle section. The auxiliary support rod 5 is fixedly connected to a second sliding rod 11 at the end away from the table body 2 and the side close to the main support rod 3. The second sliding rod 11 is slidably connected inside the second sliding groove 10. The table body 2, the main support rod 3 and the auxiliary support rod 5 form a triangular structure.

[0021] The tabletop body 2 is fixedly connected to two ends of the side near the mounting part 1 with connecting shafts 12. The end of the main support rod 3 away from the mounting part 1 is rotatably connected to the outside of the connecting shaft 12. Two symmetrically distributed mounting seats 13 are fixedly connected to the middle of the bottom of the tabletop body 2, and the end of the auxiliary support rod 5 away from the main support rod 3 is rotatably connected to the inside of the mounting seat 13.

[0022] When the table body 2 is in the folded state, the mounting part 1, the main support rod 3 and the connecting rod 4 are all on the same straight line. At this time, the first slide rod 9 at the upper end of the main support rod 3 is located at the top of the inner side of the first slide groove 8, and the second slide rod 11 at the lower end of the auxiliary support rod 5 is located at the top of the second slide groove 10. They are connected to the fixing groove 18 through the rotating buckle behind the train seat, which restricts the position of the table body 2 and keeps the table body 2 in the folded state, close to the back of the train seat.

[0023] When the user needs to unfold the table body 2, rotate the rotating buckle behind the train seat to separate it from the fixing groove 18. At this time, the table body 2 begins to move downward due to gravity, which drives the connecting shaft 12 to rotate. The main support rod 3 rotates around the mounting shaft 6, and the connecting rod 4 rotates around the mounting hole 7.

[0024] During the rotation of the main support rod 3, the first slide rod 9 at the upper end of the connecting rod 4 slides inside the first slide groove 8, gradually sliding from the top to the bottom of the first slide groove 8. At the same time, the secondary support rod 5 rotates around the mounting base 13, and the second slide rod 11 at the lower end of the secondary support rod 5 slides inside the second slide groove 10, gradually sliding from the top to the bottom of the second slide groove 10.

[0025] When the first slide rod 9 slides to the bottom of the first slide groove 8 and the second slide rod 11 slides to the bottom of the second slide groove 10, the mounting component 1, the main support rod 3, and the connecting rod 4 form a stable triangular structure. The table body 2, the main support rod 3, and the secondary support rod 5 also form a stable triangular structure. These two triangular structures work together. The triangle of the mounting component 1, the main support rod 3, and the connecting rod 4 provides support for the main support rod 3, and the triangle of the table body 2, the main support rod 3, and the secondary support rod 5 provides support for the table body 2. The weight borne by the top of the table body 2 is transmitted through the connection point between the connecting shaft 12 and the main support rod 3, and part of the weight is transmitted to the mounting component 1 through the connecting rod 4, thus achieving force distribution and stable support.

[0026] Example 2: Based on Example 1, please refer to... Figure 1 , Figure 2 and Figure 6 The following structure was also disclosed: The tabletop body 2 has a placement hole 14 at the corner near the mounting part 1 at the top. The bottom of the tabletop body 2 is fixedly connected to a stabilizing sleeve 15 aligned with the bottom of the placement hole 14. The stabilizing sleeve 15 is a retractable and foldable corrugated tube structure. The middle of the side of the tabletop body 2 away from the mounting part 1 has a fixing groove 18. The bottom of the stabilizing sleeve 15 is fixedly connected to a supporting bottom cover 16. The middle of the supporting bottom cover 16 protrudes upward to form a support seat 17. The support seat 17 has an opening in the middle and fits against the inner side of the stabilizing sleeve 15.

[0027] After the tabletop body 2 is unfolded, the user can put cup-shaped items into the placement hole 14. The bottom of the placement hole 14 is provided with a stabilizing sleeve 15. The stabilizing sleeve 15 is a retractable and foldable corrugated tube structure. A support bottom cover 16 is fixedly connected to the bottom. The support bottom cover 16 protrudes upward in the middle to form a support seat 17. The support seat 17 has an opening in the middle.

[0028] When an item is placed in the placement hole 14, the bottom of the item contacts the support cover 16. The protruding part of the support 17 supports the item and provides stable support. During the operation of the train, the item may shake or vibrate. The corrugated structure of the stabilizing sleeve 15 can undergo elastic deformation under the weight of the item, slightly compressing or stretching to absorb vibration energy, thereby reducing the shaking of the item and improving placement stability. If liquid leaks from the item, the opening in the middle of the support 17 allows the liquid to drain smoothly, preventing the liquid from accumulating inside the stabilizing sleeve 15. When the table body 2 is in the folded state, the stabilizing sleeve 15 folds accordingly. The protrusion on the top of the support 17 is flush with the top plane of the table body 2. During the folding process, the support 17 pushes out the debris inside the stabilizing sleeve 15, making it easy to clean and maintain the inside of the stabilizing sleeve 15.
