Description

Technical Field

[0001] This utility model relates to the field of high-speed rail seat technology, specifically a high-speed rail seat rotation testing device. Background Technology

[0002] High-speed rail seats are passenger facilities provided in the carriages of high-speed railway trains. They are mainly divided into business class, first class, and second class according to their class and function. The seats are usually ergonomically designed and have good comfort and support.

[0003] In the rotation test of high-speed rail seats, the directional rotation of the seat is usually achieved by the meshing transmission of gears and racks. Since the test needs to simulate multiple reciprocating rotation movements, continuous sliding and rolling friction occurs between the gears and racks, resulting in wear and heat generation on the meshing surfaces. As the test continues, the lubricant is prone to oxidation, deterioration or loss under high temperature and friction, which will lead to insufficient lubrication of the gear and rack meshing surfaces, aggravating the wear of the metal surface. If the meshing of the gears and racks is not lubricated in time, abnormal jamming or transmission failure may occur during the test, which will not only interrupt the test process, but also misjudge its durability performance and seriously affect the accuracy and repeatability of the test data.

[0004] Therefore, this utility model provides a high-speed rail seat rotation testing device to solve the above problems. Utility Model Content

[0009] As a further optimization, the inner cavity of the mounting shell is provided with a storage box. Two magnetic plates are fixedly connected to one side of the storage box, and two magnetic blocks are fixedly connected to the inner wall of one side of the mounting shell.

[0012] As a further optimization, a baffle is fitted around the outer ring of the insertion rod, and a spring is fitted around the outer ring of the insertion rod. One end of the spring is fixedly connected to one side of the corresponding baffle, and the other end of the spring is fixedly connected to the inner wall of the corresponding sliding frame.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a high-speed rail seat rotation testing device, such as... Figures 1 to 6 As shown, it includes a fixed frame 1, an mounting shell 4 is provided above the inner cavity of the fixed frame 1, a box body 5 is fixedly connected to the top of the mounting shell 4, a threaded rod 13 is provided in the inner cavity of the box body 5, a displacement block 14 is threadedly fitted on the outer ring of the threaded rod 13, a slider 15 is fixedly connected to the bottom of the displacement block 14, an oil storage box 16 is fixedly connected to the bottom of the slider 15, an oil outlet pipe 17 is fixedly connected to one side of the oil storage box 16, a rotating rod 11 is provided in the inner cavity of the mounting shell 4, a gear 12 is fitted on the outer ring of the rotating rod 11, a rack 10 is provided on one side of the gear 12, a support base 2 is fixedly connected to the bottom of the inner cavity of the fixed frame 1, and a card seat 3 is rotatably connected to the top of the support base 2 through a rotating shaft.

[0025] The two sides of the mounting shell 4 are fixedly connected to the inner walls of the adjacent fixed frame 1, respectively. A motor 28 is fixedly installed on one side of the box body 5. One end of the threaded rod 13 is rotatably connected to the inner wall of the adjacent mounting shell 4 through a rotating shaft. The other end of the threaded rod 13 passes through the inner wall of the adjacent mounting shell 4 through a bushing and is fixedly connected to the output shaft of the motor 28. A sliding groove 27 is provided on the upper surface of the mounting shell 4. The outer surface of the slider 15 is slidably connected to the inner cavity of the sliding groove 27. After the motor 28 is started, it drives the threaded rod 13 to rotate. The threaded rod 13 drives the displacement block 14, which is threaded with it, to move axially. The displacement block 14 drives the slider 15 to slide synchronously in the sliding groove 27 to achieve guidance, thereby driving the oil storage box 16 to move smoothly above the meshing area of ​​the gear 12 and the rack 10, thus providing a stable moving platform for subsequent precise lubrication.

[0026] An electric push rod 9 is fixedly installed on the inner wall of one side of the mounting shell 4. The output end of the electric push rod 9 is fixedly connected to one side of the adjacent rack 10. An oil inlet pipe is fixedly connected to one side of the oil storage box 16. An electromagnetic valve is fixedly installed on the outer ring of the oil outlet pipe 17. The rack 10 and the gear 12 are meshed through a toothed engagement. The electric push rod 9 pushes the rack 10 to perform reciprocating linear motion. The rack 10 drives the gear 12 that it meshes with to rotate. The gear 12 drives the bracket 7 and the U-shaped plate 8 to rotate through the rotating rod 11, thereby realizing the rotation test of the high-speed rail seat. The electromagnetic valve can be opened as needed to control the lubricating oil in the oil storage box 16 to drip into the meshing part through the oil outlet pipe 17, ensuring sufficient lubrication between the gear 12 and the rack 10 during long-term testing, and reducing the risk of wear and jamming.

[0027] The inner cavity of the mounting shell 4 is equipped with a storage box 6. Two magnetic plates 25 are fixedly connected to one side of the storage box 6, and two magnetic blocks 26 are fixedly connected to the inner wall of one side of the mounting shell 4. One side of the magnetic plate 25 and the corresponding side of the magnetic block 26 are attracted by magnetism. When the lubricating oil drips from the oil outlet pipe 17 to the gear 12 and the rack 10, the excess lubricating oil will drip downwards and be collected by the storage box 6 located below, preventing the oil stains from spreading. After the test is completed or when cleaning is required, the personnel can pull the storage box 6 outwards to overcome the magnetic attraction between the magnetic plate 25 and the magnetic block 26, and then the storage box 6 can be taken out for cleaning or replacement, effectively recovering excess lubricating oil and keeping the test environment clean.

[0028] The inner cavity of the fixed frame 1 is provided with a U-shaped plate 8. Several mounting through holes 24 are opened on both sides of the U-shaped plate 8. A bracket 7 is slidably connected to the inner cavity of the U-shaped plate 8. Insertion holes 18 are opened on both sides of the bracket 7. Two limiting frames 19 are fixedly connected to both sides of the U-shaped plate 8. A sliding frame 20 is slidably connected between the two corresponding limiting frames 19. An insertion rod 21 is provided in the inner cavity of the sliding frame 20. After the armrest of the high-speed rail seat is inserted between the bracket 7 and the U-shaped plate 8, the U-shaped plate 8 is adjusted upward so that its bottom fits against the armrest. Then, the sliding frame 20 drives the insertion rod 21 to move, so that one end of the insertion rod 21 passes through the mounting through hole 24 and the insertion hole 18 in sequence to lock, thereby firmly clamping the seat armrest.

[0029] The top of the rotating rod 11 is rotatably connected to the top of the inner cavity of the mounting shell 4 via a rotating shaft, and the bottom of the rotating rod 11 passes through the bottom of the inner cavity of the mounting shell 4 and is fixedly connected to the top of the bracket 7. When the gear 12 rotates, it drives the rotating rod 11, which is coaxially connected to it, to rotate synchronously. The rotating rod 11 stably transmits the rotational motion to the bracket 7, and the bracket 7 then drives the U-shaped plate 8 and the clamped high-speed rail seat to rotate as a whole, ensuring the directness and stability of the power transmission path.

[0030] A baffle 23 is fitted around the outer ring of the insertion rod 21, and a spring 22 is fitted around the outer ring of the insertion rod 21. One end of the spring 22 is fixedly connected to one side of the corresponding baffle 23, and the other end of the spring 22 is fixedly connected to the inner wall of the corresponding sliding frame 20. One end of the insertion rod 21 passes through the inner cavity of the corresponding mounting through hole 24 and is inserted into the inner cavity of the adjacent insertion hole 18. The other end of the insertion rod 21 passes through the inner wall of the corresponding sliding frame 20 and is fixedly connected to a handle. When the operator holds the handle and pulls it outward, the insertion rod 21 moves backward against the elastic force of the spring 22, causing the insertion rod 21 to disengage from the insertion hole 18. This allows the position of the bracket 7 within the U-shaped plate 8 to be adjusted. After releasing the handle, the spring 22 returns to its original shape and pushes the insertion rod 21 to automatically insert into the mounting through hole 24 and the insertion hole 18 to complete the locking.

[0031] Specifically: The operator connects the bottom mounting part of the high-speed rail seat to the inner cavity of the card holder 3. Then, the operator holds the handle and pulls the insertion rod 21 outward to apply force. At this time, the spring 22 is compressed and deformed, and the sliding frame 20 slides synchronously in the inner cavity of the corresponding limiting frame 19. Next, the armrest of the high-speed rail seat is inserted between the bracket 7 and the U-shaped plate 8, and the U-shaped plate 8 is pulled upward according to the size of the armrest so that its interior fits tightly with the bottom of the armrest. Then, the operator releases the handle, and under the elastic action of the spring 22, the spring 22 returns to its original state, driving the insertion rod 21 to be inserted into the inner cavity of the corresponding mounting through hole 24 and the inner cavity of the insertion hole 18 in sequence to complete the insertion, realizing the locking between the bracket 7 and the U-shaped plate 8, thereby stably applying vertical pressure. On the high-speed rail seat, to ensure the overall stability of the seat during subsequent rotation tests and prevent test deviations due to loosening, the electric push rod 9 is then activated. The electric push rod 9 drives the rack 10 to reciprocate linearly. During the movement, the rack 10 remains engaged with the gear 12, thereby driving the gear 12 to rotate periodically. The rotation of the gear 12 drives the rotating rod 11 to rotate synchronously. The rotation of the rotating rod 11 drives the connected bracket 7 to rotate. The rotation of the bracket 7 drives the U-shaped plate 8 and the clamped high-speed rail seat to rotate together, realizing the durability test of the seat rotation function. This process, through the multiple reciprocating drives of the rack 10, causes the gear 12 to rotate multiple times, thus completing the long-term, high-frequency test of the seat rotation mechanism. During the rate simulation test, due to the continuous meshing and transmission between gear 12 and rack 10, friction generates heat and may cause lubricant deterioration or loss. The operator starts motor 28, which drives the threaded rod 13 to rotate. The rotation of the threaded rod 13 causes the displacement block 14, which is threadedly engaged with it, to move smoothly axially within the inner cavity of the housing 5. At this time, the slider 15 slides synchronously within the inner cavity of the slide groove 27, serving as a guide and preventing deflection, ensuring the smooth operation of the displacement block 14. The movement of the displacement block 14 causes the oil storage box 16 connected to it to move synchronously above the meshing area of ​​gear 12 and rack 10. Subsequently, the solenoid valve opens, controlling the lubricating oil stored inside the oil storage box 16 to drip onto gear 12 through the oil outlet pipe 17. The meshing teeth of the rack 10 provide lubrication, effectively replenishing the lubricant lost during long-term operation and preventing abnormal wear or jamming due to insufficient lubrication. Excess lubricating oil dripping during the process falls into the collection box 6 for centralized collection, preventing oil pollution of the testing environment. When cleaning or changing the lubricating oil is required, personnel can pull out the collection box 6 by applying force to release the magnetic connection between the magnetic suction plate 25 on the outside of the collection box 6 and the corresponding magnetic block 26 on the mounting shell 4, allowing the collection box 6 to be easily removed from the inside of the mounting shell 4 for easy maintenance and reuse. The entire testing process operates continuously under stable clamping, reliable transmission, and controllable lubrication conditions, ensuring the continuity and accuracy of the test data.

[0032] 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.
