Description

Technical Field

[0001] The invention relates to the technical field of seat and mattress support, in particular to a discrete module support structure. Background Art

[0002] Currently, most of the supporting structure products on the market, such as mattresses, sofas, office chairs, car, ship and airplane seats, use textiles or leather as contact surfaces, and are filled with cushioning materials such as sponge, latex, and coconut palm, and then use several large-diameter springs or serpentine springs to provide elasticity.

[0003] For example, a sofa support structure with a publication number of (CN 213605424 U) is provided with a support device between a backrest and a massage device. A cushion body is provided to accommodate the massage device and adjust the vibration frequency of the massage device. An airbag is provided on the cushion body to conveniently adjust the comfort of the backrest. The fit between the backrest and the human back is adjusted by adjusting the inflation state of the airbag, so that the back is more closely fitted to the massage device and the massage effect is improved.

[0004] However, this structure has the following problems: 1. The textile material has a lateral force component, that is, there is a lateral pulling force, so that the part that should sink does not sink to the appropriate depth. As a result, long-term accumulation may cause structural bending of bones such as the human spine (the sense of lateral force is similar to that of a hammock); 2. The textile material and the soft filling material wrapped in it are prone to health hazards, including difficulty in cleaning. If you need to remove the external textile for cleaning, and the filling material layer may be impossible to clean or difficult to clean. If the product cannot be disassembled, it needs to be cleaned by a professional suction cleaning machine, which incurs additional expenses, and the air permeability is poor or ventilation equipment is required to achieve normal air permeability. To this end, we propose a discrete module support structure to solve the above technical problems. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the present invention provides a discrete modular support structure, which has the characteristics of providing support force only perpendicular to the contact surface, supporting without pulling, and providing pure vertical support according to the curvature of the body's bones and muscles; the support force is adjustable; the structure is breathable, and the problem of airtight contact materials is completely solved; it is maintenance-free, and does not use textile cushioning pads, but can be directly rinsed with water; it has the advantages of being disassembled in blocks for packaging, transportation, maintenance and storage, and solves the above-mentioned technical problems.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a discrete modular support structure, including a push rod, a piston rod is arranged at the bottom of the push rod, the outer surface of the piston rod is connected to a spring with a diameter matching the bottom of the push rod, a support plate is arranged at the bottom of the push rod, a through hole matching the outer surface of the piston rod is arranged at the connection between the top surface of the support plate and the push rod, the outer side of the support plate is connected to an outer shell, the inner side of the outer shell is sleeved with the push rod, and the outer shell is also provided with a docking portion for connecting to other outer shells.

[0009] Preferably, the docking portion includes an outer shell surface installed on the outer shell, and the outer shell surface is provided with recesses that fit the side walls of the push rod at intervals, and the inner side of the recess fits with the push rod. Two of the recesses form a group, and one positive and one negative are arranged at intervals on the inner and outer sides of the outer shell surface, and multiple groups of the recesses cut the outer shell surface into a wavy shape.

[0010] Preferably, the docking portion further comprises a sliding opening provided at the middle end of the outer shell surface, the sliding opening is located on a side of the outer shell surface close to the top rod, and the inner side of the sliding opening forms a sliding connection with the support plate.

[0011] Preferably, the cross section of the push rod is a geometric shape, including polygonal, elliptical and circular shapes. The push rod is connected to the piston rod through the bottom cavity piston. The top of the spring contacts the bottom surface of the push rod, and the bottom is fixedly connected to the bottom of the piston rod.

[0012] Preferably, the support plate is sleeved on the bottom of the top rod through a through hole.

[0013] Preferably, the through hole array is opened on the top surface of the support plate, and the through holes penetrate the support plate, and the inner side of the through holes is slidably connected to the push rod.

[0014] Preferably, the outer shell is sleeved with a support plate on which a plurality of push rods are installed, and the outer shell is a hollow body with upper and lower ends connected.

[0015] Preferably, the through opening is opened in the front and rear walls of the shell and penetrates through them, and the inner side of the through opening forms a sliding connection with the surface of the shell.

[0016] Compared with the prior art, the present invention provides a discrete module support structure, which has the following beneficial effects:

[0017] 1. The present invention has a geometric cross-section of the push rod, and the points on the tops of multiple push rods form a support surface. When the top of the push rod is subjected to pressure, since there is no connection basis between the multiple push rods, the force borne by each push rod will not be dispersed. Furthermore, as the single push rod is subjected to the downward pressure of the top surface, it will move downward and press down the spring. At this time, the piston rod inside the spring will penetrate into the cavity inside the push rod, ensuring that the push rod will not be skewed due to pressure, and springs of different stiffness can be switched to change the support strength, thereby achieving the beneficial effects of only removing the lateral pulling force, only providing the support force perpendicular to the contact surface, providing appropriate vertical support according to the curvature of the body, and adjustable support force.

[0018] 2. According to the present invention, when the user sits down, the surface of the body will contact the contact surface formed by multiple top rods. At this time, the contact surface will be decomposed into multiple supporting points. The top rod of a single supporting point will be responsible for supporting a certain area. At the same time, the multiple top rods are constructed separately and there will be no connecting surfaces. Therefore, the ventilation performance is better, structural breathability is achieved, and the beneficial effect of completely solving the problem of airtightness of the contact material is achieved.

[0019] 3. The present invention forms a supporting surface through the points on the tops of multiple push rods. When the tops of the push rods are under pressure, since there is no connection basis between the multiple push rods, it is simpler to clean by directly pouring detergent to complete the soaking, sterilization and decontamination. The side walls of the outer shells are matched with each other by using the wave shape, so that multiple outer shells can be brought close together. When disassembling, it is only necessary to disconnect the outer shell from the sofa or other seats, and the outer shells can be carried separately, which achieves the benefits of no maintenance, no textile cushioning and padding, and direct washing with water; and the beneficial effects of block disassembly, packaging, transportation, maintenance and storage.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-5 A discrete module support structure includes a push rod 1, a piston rod 2 is arranged at the bottom of the push rod 1, the outer surface of the piston rod 2 is connected to a spring 201 at the bottom of the push rod 1 with a diameter that matches the bottom of the push rod 1, a support plate 3 is arranged at the bottom of the push rod 1, a through hole 301 that matches the outer surface of the piston rod 2 is arranged at the connection between the top surface of the support plate 3 and the push rod 1, the outer side of the support plate 3 is connected to the outer shell 4, the inner side of the outer shell 4 is sleeved with the push rod 1, and a through hole 5 for plugging in the support plate 3 is also provided at the middle end of the front and rear walls, and the outer shell 4 is also provided with a docking portion for connecting other outer shells 4.

[0028] Furthermore, the docking portion includes an outer shell surface 6 installed on the outer shell 4, and the outer shell surface 6 is arranged with recesses 601 that fit the side wall of the push rod 1 at intervals. The inner side of the recess 601 fits with the push rod 1. Two recesses 601 form a group, and one positive and one negative are arranged at intervals on the inner and outer sides of the outer shell surface 6. Multiple groups of recesses 601 cut the outer shell surface 6 into a wavy shape.

[0029] Furthermore, a support surface is formed by the points at the tops of the multiple push rods 1. When the tops of the push rods 1 are subjected to pressure, since there is no connection base between the multiple push rods 1, the force borne by each push rod 1 will not be dispersed. Furthermore, as the single push rod 1 is subjected to the downward pressure of the top surface, it will move downward and press down the spring 201. At this time, the piston rod 2 inside the spring 201 will penetrate into the cavity on the lower side of the support plate 3 to ensure that the push rod 1 will not be skewed due to pressure.

[0030] Furthermore, the through holes 301 opened in the support plate 3 support multiple push rods 1 so that the push rods 1 become a support surface.

[0031] Furthermore, the push rod 1 is wrapped by the through hole 301, so that the push rod 1 is limited in the through hole 301 so that it can only slide up and down.

[0032] Furthermore, the support plate 3 is clamped by the shell 4, so that the top rod 1 is accommodated inside the shell 4 to prevent multiple top rods 1 from falling randomly. The shell 4 with the top rod 1 installed can be installed on the surface of a sofa or other seat. When a user sits down, the body surface will contact the contact surface formed by the multiple top rods 1. At this time, the contact surface will be decomposed into multiple supporting points. The top rod 1 of a single supporting point will be responsible for supporting a certain area. At the same time, the multiple top rods 1 are constructed separately and there will be no connecting surfaces. Therefore, the ventilation performance is better, and cleaning is simpler. Just pour the detergent to complete the soaking, sterilization and decontamination.

[0033] When in use, the user sits on the device, and the entire push rod 1 moves downward, wherein the piston rod 2 connected to the push rod 1 moves downward through the through hole 301 into the lower space formed by the shell 4 and the support plate 3, and the shell surface 6 wraps the two sides of the shell 4, and utilizes the wave-shaped matching characteristics to achieve the multiple shells 4 close together. When disassembling, it is only necessary to interrupt the connection between the shell 4 and the sofa or other seats, and the shell 4 can be carried separately. The support surface is formed by the points on the top of the multiple push rods 1. When the top of the push rod 1 is under pressure, since there is no connection foundation between the multiple push rods 1, the force borne by each push rod 1 will not be divided. Dispersion, further, as the single push rod 1 is subjected to the downward pressure of the top surface, it will move downward and press down the spring 201. At this time, the piston rod 2 inside the spring 201 will penetrate into the cavity on the lower side of the support plate 3 to ensure that the push rod 1 will not be skewed due to pressure. When a user sits down, the body surface will contact the contact surface formed by multiple push rods 1. At this time, the contact surface will be decomposed into multiple supporting points. The push rod 1 of a single supporting point will be responsible for supporting a certain area. At the same time, the multiple push rods 1 are constructed separately without any connecting surface. Therefore, the ventilation performance is better, and cleaning is simpler. Just pour the detergent to complete the soaking, sterilization and decontamination.
