A slow-rebound spring air-permeable cushion

Abstract

This utility model relates to the field of seat cushion technology and discloses a slow-rebound spring breathable seat cushion, including a base, a flexible pad on the top of the base, a fitting groove at the top of the base, and several ventilation grooves at the bottom of the base. Several first mounting grooves are formed on the inner wall of the fitting grooves, and a fixing cylinder is fixedly installed on the inner wall of each of the first mounting grooves. When a person sits on the flexible pad, the pressure causes the sleeve and piston rod to move downwards. Part of the pressure is discharged to the outside through the ventilation grooves, and part flows into the ventilation holes through the connecting holes to reduce the stuffiness near the flexible pad and achieve breathability. At the same time, the spring is compressed and stores energy, which can disperse the pressure. After the pressure decreases, the spring releases energy and resets, and the piston rod simultaneously resets upwards. The space inside the fixing cylinder expands to form a negative pressure, and outside air enters through the ventilation grooves at the bottom of the base and is drawn in through the through holes of the fixing cylinder to replenish it. Finally, the flexible pad returns to its initial shape, achieving a slow-rebound effect and avoiding instantaneous bounce.

Description

Technical Field

[0001] This utility model relates to the field of seat cushion technology, and in particular to a slow rebound spring breathable seat cushion. Background Technology

[0002] Slow rebound spring breathable seat cushions are a type of seat auxiliary device that combines slow rebound material, spring structure, and breathable design. They are mainly used to improve the comfort, support, and user experience of seating. They can slowly deform according to human body pressure and temperature, conforming to the curves of the buttocks and waist. After the pressure is released, they will gradually return to their original shape, avoiding the local pressure feeling of traditional hard seat cushions.

[0003] Traditional seat cushions lack effective air circulation channels. When people sit for long periods of time, the area where the buttocks contact the seat cushion can easily become hot and humid, reducing riding comfort. At the same time, the seat cushion recovers quickly after being compressed, resulting in a sudden bounce. This not only fails to effectively distribute the pressure on the body, but may also cause a bumpy or uncomfortable feeling due to the rebound force not being synchronized with the body's movements. Furthermore, the disassembly and assembly of traditional seat cushions are relatively complicated, and it is difficult to replace the flexible parts individually if they are damaged. Based on these issues, a slow-rebound spring breathable seat cushion is proposed for improvement. Utility Model Content

[0004] In view of the above-mentioned problems of insufficient breathability and rapid recovery after being compressed by existing traditional seat cushions, as well as the relatively complicated disassembly and assembly of traditional seat cushions, this utility model is proposed.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a slow rebound spring breathable seat cushion, including a base, a flexible pad above the base, a fitting groove at the top of the base, a plurality of ventilation grooves at the bottom of the base, a plurality of first mounting grooves on the inner wall of the fitting groove, a fixing cylinder fixedly installed on the inner wall of the plurality of first mounting grooves, and a through hole on the inner wall of the fixing cylinder, the through hole communicating with the interior of the ventilation groove;

[0006] The flexible pad has several ventilation holes inside, which are connected to the connecting holes. The bottom of the flexible pad has several second mounting grooves, and sleeves are fixedly installed on the inner walls of the second mounting grooves. The sleeves are slidably connected to the outer surface of the fixed cylinder, and piston rods are fixedly connected to the inner walls of the sleeves. The piston rods are slidably connected to the inner walls of the fixed cylinder.

[0007] As a preferred embodiment, a spring is movably connected to the inner wall of the sleeve, and the bottom end of the spring contacts the top end of the fixed cylinder.

[0008] As a preferred embodiment, the inner wall of the fitting groove is further provided with a number of connecting holes, which are connected to the interior of the ventilation groove.

[0009] As a preferred embodiment, the flexible pad is fitted into the inner wall of the fitting groove, and the top of the flexible pad is arc-shaped.

[0010] As a preferred embodiment, the inner wall of the fitting groove is fixedly equipped with a plurality of velvet surfaces, and the bottom end of the flexible pad is fixedly equipped with a plurality of hook surfaces that are adapted to the velvet surfaces.

[0011] As a preferred embodiment, the flexible pad is provided with symmetrical pull straps at its top end, and the pull straps are made of elastic material.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] 1. When a person sits on the flexible mat, the pressure causes the sleeve and piston rod to move downwards. Part of the pressure is discharged to the outside through the ventilation groove, and part of the pressure flows into the ventilation hole through the connecting hole to reduce the stuffiness near the flexible mat and achieve ventilation. At the same time, the spring is compressed and stores energy, which can disperse the pressure. After the pressure decreases, the spring releases energy and resets, and the piston rod resets upwards in sync. The space inside the fixed cylinder expands to form a negative pressure. Outside air enters through the ventilation groove at the bottom of the base and is sucked in through the through hole of the fixed cylinder to replenish it. Finally, the flexible mat returns to its initial shape, achieving a slow rebound effect and avoiding instantaneous bounce.

[0014] 2. This utility model enhances the stability of the flexible pad within the fitting groove by bonding the fleece and hook surfaces together, while preventing the flexible pad from detaching. The elastic material of the pull strap allows users to easily remove the flexible pad by pulling, making it convenient to disassemble and replace quickly, reducing maintenance time. At the same time, the elasticity ensures that the pull strap stays close to the top of the flexible pad, avoiding affecting the fit and comfort when sitting, thus balancing practicality and durability.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1-4 This is the first embodiment of the present utility model, which provides a slow rebound spring breathable seat cushion, including a base 1, a flexible pad 2 above the base 1, a fitting groove 11 at the top of the base 1, a plurality of ventilation grooves 13 at the bottom of the base 1, a plurality of first mounting grooves 12 on the inner wall of the fitting groove 11, a fixing cylinder 3 fixedly installed on the inner wall of the plurality of first mounting grooves 12, and a through hole 31 on the inner wall of the fixing cylinder 3, which is connected to the interior of the ventilation grooves 13.

[0023] The flexible pad 2 has several ventilation holes 21 inside, and the ventilation holes 21 are connected to the connection holes 14. The bottom of the flexible pad 2 has several second mounting grooves 22. A sleeve 4 is fixedly installed on the inner wall of the several second mounting grooves 22. The sleeve 4 is slidably connected to the outer surface of the fixed cylinder 3. A piston rod 5 is fixedly connected to the inner wall of the sleeve 4. The piston rod 5 is slidably connected to the inner wall of the fixed cylinder 3.

[0024] A spring 6 is movably connected to the inner wall of the sleeve 4, and the bottom end of the spring 6 contacts the top end of the fixed sleeve 3;

[0025] The inner wall of the fitting groove 11 is also provided with several connecting holes 14, which are connected to the interior of the ventilation groove 13.

[0026] During use, when a person sits on the flexible pad 2, the flexible pad 2 is pressed and moves downward, causing the sleeve 4 at its bottom end to move downward synchronously. The sleeve 4 slides along the outer surface of the fixed cylinder 3. At this time, the spring 6 on the inner wall of the sleeve 4 is compressed, converting the pressure of the human body into the elastic potential energy of the spring 6. At the same time, the piston rod 5 on the inner wall of the sleeve 4 slides downward along the inner wall of the fixed cylinder 3, and the air in the fixed cylinder 3 is squeezed. The air flows into the ventilation groove 13 of the base 1 through the through hole 31. Part of it is discharged to the outside from the ventilation groove 13, and part of it flows into the ventilation hole 21 through the connecting hole 14, which can timely discharge the hot and humid air near the flexible pad 2, reduce the stuffiness, and achieve breathability.

[0027] When the human body leaves or reduces the pressure on the flexible pad 2, the compressed spring 6 releases its elastic potential energy, pushing the sleeve 4 to slide upward along the fixed cylinder 3. The piston rod 5 simultaneously returns to its original position, and the space inside the fixed cylinder 3 expands to form a negative pressure. Outside air enters through the ventilation slot 13 at the bottom of the base 1 and is sucked in through the through hole 31 of the fixed cylinder 3 to replenish it, ultimately causing the flexible pad 2 to return to its initial shape, achieving a slow rebound effect and avoiding instantaneous bounce.

[0028] When a person sits on the flexible pad 2, the pressure causes the sleeve 4 and piston rod 5 to move downwards. Part of the pressure is discharged to the outside through the ventilation groove 13, and part flows into the ventilation hole 21 through the connecting hole 14 to reduce the stuffiness near the flexible pad 2 and achieve ventilation. At the same time, the spring 6 is compressed and stores energy, which can disperse the pressure. After the pressure decreases, the spring 6 releases energy and resets, and the piston rod 5 resets upwards in sync. The space inside the fixed cylinder 3 expands to form a negative pressure. Outside air enters through the ventilation groove 13 at the bottom of the base 1 and is sucked in through the through hole 31 of the fixed cylinder 3 to replenish it. Finally, the flexible pad 2 returns to its initial shape, achieving a slow rebound effect and avoiding instantaneous bounce.

[0029] Reference Figures 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the flexible pad 2 is fitted into the inner wall of the fitting groove 11, and the top of the flexible pad 2 is arc-shaped.

[0030] Several velvet surfaces 7 are fixedly installed on the inner wall of the fitting groove 11, and several hook surfaces 8 that are compatible with the velvet surfaces 7 are fixedly installed at the bottom of the flexible pad 2.

[0031] The top of the flexible pad 2 is symmetrically provided with pull straps 23, which are made of elastic material.

[0032] During use, the top of the flexible pad 2 is arc-shaped, which can better conform to the curves of the human body and improve the fit and comfort when sitting. The combination of the plush surface 7 and the hook surface 8 can enhance the stability of the flexible pad 2 in the fitting groove 11, prevent the flexible pad 2 from falling off, and make the flexible pad 2 easy to disassemble. The pull strap 23 is made of elastic material, which makes it easy for users to remove the flexible pad 2 by pulling. The elasticity of the pull strap 23 keeps it close to the top of the flexible pad 2, so as not to affect the fit and comfort when sitting, thus taking into account both practicality and durability.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
