Technical Field
[0001] This utility model relates to the field of high-speed rail seat technology, specifically a high-speed rail seat with an adjustable backrest. Background Technology
[0002] Currently, my country's road transportation has developed rapidly, becoming one of the main modes of transportation for citizens, with high-speed rail being the fastest. As the high-speed rail network continues to improve and operational efficiency continues to rise, passengers' demands for travel experience are becoming increasingly stringent. High-speed rail seats, as key facilities that come into direct contact with passengers, directly affect ride comfort. While existing high-speed rail seats generally meet daily needs, there are still some shortcomings that require improvement.
[0003] The high-speed rail seats widely used in the market generally suffer from low adaptability and cumbersome operation. Most high-speed rail seats have headrests that only support 2-3 limited height adjustments, which cannot quickly meet the neck support needs of passengers of different heights. During long-distance travel, inappropriate neck support not only reduces riding comfort, but may also cause neck fatigue or even injury. To address these issues, we propose a high-speed rail seat with an adjustable backrest. Utility Model Content
[0004] The purpose of this invention is to provide a high-speed rail seat with an adjustable backrest to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-speed rail seat with an adjustable backrest, comprising a high-speed rail seat and a backrest installed on the high-speed rail seat. A sleeve is installed at the upper end of the backrest, and sleeve holes are provided on both sides of the sleeve. A sliding rod is provided in each of the two sets of sleeve holes, and a headrest is installed at the top of each of the two sets of sliding rods. Multiple sets of positioning holes are equally spaced on each of the two sets of sliding rods. A fixing seat is installed in the middle of the sleeve, and a guide sliding hole is provided inside the upper end of the fixing seat. Two sets of guide sliders are provided in the guide sliding hole, and a positioning rod is fixed at one opposite end of each of the two sets of guide sliders. The opposite ends of each of the two sets of positioning rods can be inserted into the positioning holes on the two sets of sliding rods. A pull ring is fixed at the top of each of the two sets of guide sliders, and a return spring is provided between the two sets of guide sliders.
[0006] As a further preferred embodiment of this technical solution, both sets of slide rods are provided with a turntable at their bottom ends, both sets of turntables are provided with a threaded post at their top ends, and both sets of slide rods are provided with a threaded groove corresponding to the threaded post at their bottom ends.
[0007] As a further preferred embodiment of this technical solution, the two ends of the reset spring are respectively connected to two sets of guide sliders, and the two sets of guide sliders are elastically connected to each other through the reset spring.
[0008] As a further preferred embodiment of this technical solution, the outer wall of the guide slider is fully fitted with the inner wall of the guide sliding hole on the fixed base, and the guide slider and the guide sliding hole are slidably connected.
[0009] As a further preferred embodiment of this technical solution, the diameter of the positioning rod is the same as the inner diameter of the positioning hole on the slide rod.
[0010] As a further preferred embodiment of this technical solution, the surface of the turntable is provided with anti-slip texture.
[0011] This utility model provides a high-speed rail seat with an adjustable backrest, which has the following advantages:
[0012] 1. This utility model has a backrest with a fixed base and a multi-level adjustable headrest installed on the base. When adjusted to a suitable position, the pull ring is released, and the return spring releases its elastic force to push the guide slider back to its original position, allowing the positioning rod to re-engage into the positioning hole of the corresponding height of the slide rod for fixation. This facilitates quick adjustment of the positioning hole to different heights, improves the applicability of the positioning hole, and increases passenger comfort.
[0013] 2. This utility model features detachable turntables installed on the slide rods. Two sets of turntables are threadedly connected to the bottom of the two sets of slide rods via threaded posts. This prevents the two sets of slide rods from completely disengaging from the two sets of sleeve holes on the sleeve base under the action of the two sets of turntables, thus effectively preventing the headrest from falling off. When the headrest needs to be replaced, the two sets of turntables can be rotated to quickly move away from the bottom of the two sets of slide rods, releasing the restriction on the slide rods. This facilitates quick and easy disassembly of the headrest, improving the convenience of the device during use. Attached Figure Description

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.
[0021] It should be noted that all directional indicators (such as up, down, left, right, front, back, 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.
[0022] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.
[0023] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
[0024] This utility model provides a technical solution: such as Figures 1 to 5As shown in this embodiment, a high-speed rail seat with an adjustable backrest includes a high-speed rail seat 1 and a backrest 2 installed on the high-speed rail seat 1. A cover 3 is installed on the upper end of the backrest 2. Cover holes 4 are opened on both sides of the cover 3. Slide rods 5 are provided in both sets of cover holes 4. Headrests 6 are installed at the top of the two sets of slide rods 5. Multiple sets of positioning holes 7 are opened at equal intervals on both sets of slide rods 5. A fixing seat 8 is installed in the middle of the cover 3. A guide sliding hole 9 is opened inside the upper end of the fixing seat 8. Two sets of guide sliders 10 are provided in the guide sliding hole 9. Positioning rods 11 are fixed at opposite ends of the two sets of guide sliders 10. The opposite ends of the two sets of positioning rods 11 can be inserted into the positioning holes 7 on the two sets of slide rods 5. Pull rings 12 are fixed at the top of the two sets of guide sliders 10. A return spring 13 is provided between the two sets of guide sliders 10.
[0025] In use, the user pulls the pull ring 12 to move the guide slider 10 within the guide hole 9, causing the positioning rod 11 to disengage from the positioning hole 7 of the slide rod 5. At this time, the headrest 6 can be adjusted up and down, allowing the headrest 6 to move the two sets of slide rods 5 along the two sets of sleeve holes 4 on the sleeve 3. When adjusted to a suitable position, the pull ring 12 is released, and the return spring 13 releases its elastic force to push the guide slider 10 back to its original position, allowing the positioning rod 11 to re-engage into the positioning hole 7 at the corresponding height of the slide rod 5 for fixation. This facilitates quick adjustment of the positioning hole 7 to different heights, improves the applicability of the positioning hole 7, and increases passenger comfort.
[0026] In other embodiments, a turntable 14 is provided at the bottom of both sets of slide rods 5, a threaded post 15 is installed at the top of both sets of turntables 14, and a threaded groove corresponding to the threaded post 15 is opened at the bottom of both sets of slide rods 5.
[0027] By installing detachable turntables 14 on the slide rods 5, and connecting the two sets of turntables 14 to the bottom of the two sets of slide rods 5 via threaded posts 15, the two sets of slide rods 5 are prevented from completely disengaging from the two sets of sleeve holes 4 on the sleeve base 3 under the action of the two sets of turntables 14, thus effectively preventing the headrest 6 from falling off. When the headrest 6 needs to be replaced, the two sets of turntables 14 can be rotated to quickly move away from the bottom of the two sets of slide rods 5, releasing the restriction on the slide rods 5, thus facilitating the quick and easy disassembly of the headrest 6 and improving the convenience of using the device.
[0028] In other embodiments, the two ends of the return spring 13 are respectively connected to two sets of guide sliders 10, and the two sets of guide sliders 10 are elastically connected to each other through the return spring 13;
[0029] This design allows the return spring 13 to apply a continuous opposing elastic force to the two sets of guide sliders 10, enabling the two sets of guide sliders 10 to drive the two sets of positioning rods 11 to quickly insert into the positioning holes 7 on the two sets of slide rods 5.
[0030] In other embodiments, the outer wall of the guide slider 10 is fully fitted with the inner wall of the guide sliding hole 9 on the fixed base 8, and the guide slider 10 and the guide sliding hole 9 are slidably connected.
[0031] With this design, when the guide slider 10 moves laterally along the guide hole 9 on the fixed base 8, it can prevent the guide slider 10 from shaking during the movement, so that the guide slider 10 can drive the positioning rod 11 to quickly insert into the positioning hole 7 on the slide rod 5.
[0032] In other embodiments, the diameter of the positioning rod 11 is the same as the inner diameter of the positioning hole 7 on the slide rod 5;
[0033] With this design, when the end of the positioning rod 11 is inserted into the positioning hole 7 on the slide rod 5, the positioning rod 11 can form a stable limiting effect on the slide rod 5, thereby improving the stability of the headrest 6 during use.
[0034] In other embodiments, the surface of the turntable 14 is provided with anti-slip texture;
[0035] This design effectively increases the friction between the hand and the surface of the turntable 14, thus facilitating the effective rotation of the turntable 14.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
