Description

Technical Field

[0001] The present application relates to the technical field of mattresses, and in particular to a shock-absorbing device for mattresses. Background Art

[0002] Currently, most of the common spring mattresses on the market use foamed sheets as the mattress. Through holes are provided in the mattress body to place springs to enhance its bearing capacity, and the outer cover of the mattress is made of fabric surface fabric.

[0003] For example, the spring mattress mentioned in the existing Chinese patent publication (authorization publication number: CN104643727B) can quickly fix the springs through spring positioning parts, so that no hand tools are required during the installation process, achieving the effect of rapid assembly and greatly saving assembly time. However, when this kind of spring mattress is actually used, it only has one layer of springs for buffering, so that the elasticity of the mattress is relatively fixed, and it cannot give users a better and richer experience. Moreover, this kind of mattress does not have an active ventilation function. Only several holes are provided around the periphery of the fabric surface fabric covering the outer cover of the mattress as passive natural air convection holes, making it difficult to release the humidity, temperature, and human odor inside the covered mattress body, thus affecting the user's use.

Detailed implementation manners

[0037] The following is a further detailed description of this application in combination with the attached Figures 1-7 drawings.

[0038] The embodiment of this application discloses a shock-absorbing device for a mattress.

[0039] As Figure 1As shown in the figure, a shock-absorbing device for a mattress in this embodiment includes a cushion body 100 and an adjusting cushion 110 disposed below the cushion body 100. The cushion body 100 includes a backing plate 101 and a rubber pad 102 disposed on the backing plate 101. Threaded holes 103 are evenly distributed on the backing plate 101. The rubber pad 102 is provided with shock-absorbing grooves 104 with openings facing the backing plate 101. Vent holes 105 are evenly distributed on the side walls of the shock-absorbing grooves 104. Shock-absorbing blind holes 106 corresponding to the threaded holes 103 are provided on the top walls of the shock-absorbing grooves 104;

[0040] Buffer components 120 with upper ends extending into the corresponding shock-absorbing blind holes 106 are disposed in the threaded holes 103. The buffer components 120 are used for buffering the cushion body 100. An air-permeable component for ventilating the shock-absorbing grooves 104 is provided at the lower end of the buffer components 120;

[0041] The adjusting cushion 110 includes a base 130. An adjusting groove 131 with an opening facing the cushion body 100 is provided in the base 130. A liftable adjusting plate 150 is provided in the adjusting groove 131 through an adjusting component 140. Convex columns 151 corresponding to the buffer components 120 are provided on the adjusting plate 150. A first spring 160 for shock-absorbing the cushion body 100 is sleeved between the buffer components 120 and the corresponding convex columns 151.

[0042] In this embodiment, the rubber pad 102 and the backing plate 101 can be made of materials such as rubber and foamed sheet pads in the prior art, which are all prior arts and will not be elaborated here;

[0043] Among them, through the settings of the threaded holes 103, the shock-absorbing grooves 104 and the shock-absorbing blind holes 106, the disassembly and assembly of the buffer components 120 in the cushion body 100 are preferably realized;

[0044] Among them, through the setting of the buffer components 120, the buffer components 120 can buffer the user lying on the rubber pad 102. At the same time, through the settings of the adjusting plate 150, the convex columns 151 and the first spring 160, the first spring 160 can shock-absorb and buffer the entire cushion body 100 located on the adjusting cushion 110. Thus, the shock-absorbing device can use the buffer components 120 and the first spring 160 to perform multiple shock-absorbing buffers on the cushion body 100, making the elasticity of the mattress formed between the cushion body 100 and the adjusting cushion 110 more sufficient and able to give the user a better and richer experience. The cooperation of the convex columns 151 and the buffer components 120 can preferably realize the disassembly and assembly of the first spring 160;

[0045] In this embodiment, through the setting of the adjusting member, the user can lift and lower the adjusting plate 150 in the adjusting groove 131 through the adjusting member, thereby adjusting the distance between the cushion body 100 and the adjusting cushion 110 and realizing the adjustment of the height of the mattress;

[0046] In this embodiment, through the provision of the ventilation component and the ventilation holes 105, when a user lies on the cushion body 100, when the buffering component 120 buffers the user on the cushion body 100, it drives the ventilation component to open, enabling the air in the shock absorption groove 104 where the user lies on the cushion body 100 to be discharged through the ventilation component. In cooperation with the provision of the ventilation holes 105, the air outside the mattress flows into the shock absorption groove 104 through the ventilation holes 105 and is discharged through the ventilation component, thereby forming air convection. Preferably, the water vapor, odor, etc. inside the mattress where the user lies is discharged along with the air convection, thus improving the ventilation effect of the mattress.

[0047] Combined with Figure 2 and Figure 3 As shown, in this embodiment, the buffering component 120 includes a buffer column 200 threadedly connected to the threaded hole 103. The buffer column 200 is provided with a cavity with upper and lower openings. A partition plate 310 is provided in the cavity to divide the cavity into an upper cavity 311a and a lower cavity 311b.

[0048] At the opening of the upper cavity 311a, a first plug ring 210 is threadedly provided. In the upper cavity 311a, there is a buffer rod 220 which is provided with a buffer spring 320 and has an upper end extending out of the first plug ring 210 for buffering the rubber pad 102.

[0049] Through the structure in this embodiment, the buffer spring 320 always pushes the buffer rod 220 to extend out of the upper end of the buffer column 200, and the upper end of the buffer rod 220 cooperates with the upper end wall of the shock absorption blind hole 106. When a user lies on the rubber pad 102, the buffer spring 320 can buffer the force on the buffer rod 220.

[0050] Among them, through the provision of the first plug ring 210, the disassembly and assembly of the buffer spring 320 and the buffer rod 220 in the upper cavity 311a are preferably realized.

[0051] Combined with Figure 3 As shown, in this embodiment, the lower end of the buffer rod 220 penetrates through the partition plate 310 and extends into the lower cavity 311b. A first convex ring 331 is provided on the buffer rod 220 in the upper cavity 311a. The buffer spring 320 is sleeved outside the buffer rod 220 and is used to drive the first convex ring 331 to move upward to realize the upper end of the buffer rod 220 extending out of the first plug ring 210.

[0052] A first air hole 201 is provided on the side wall of the upper cavity 311a along its circumferential direction. A gas guiding groove 332 for communicating with the lower cavity 311b is provided on the side wall of the buffer rod 220 along its axial direction. The ventilation component is provided at the opening of the lower cavity 311b, and the ventilation component is used to discharge the airflow entering the buffer column 200.

[0053] Through the setting of the first convex ring 331 in this embodiment, it is preferably realized that the buffer spring 320 drives the buffer rod 220 to extend. Among them, through the setting of the first air hole 201 and the air guide groove 332, the air entering the shock absorption groove 104 from the air permeable hole 105 can enter the upper cavity 311a through the first air hole 201 and flow into the lower cavity 311b through the air guide groove 332, so that it can discharge the air entering the lower cavity 311b through the air permeable component, thereby forming an air convection at the buffer component 120.

[0054] Combined with Figure 3 As shown, in this embodiment, the air permeable component includes an air permeable column 340 threadedly connected to the lower cavity 311b. An air permeable cavity 341 is provided in the air permeable column 340. A second blocking ring 350 is threadedly connected to the lower end opening of the air permeable cavity 341. A piston column 360 with its upper end extending out of the air permeable column 340 is provided in the air permeable cavity 341. The lower end of the piston column 360 penetrates through the second blocking ring 350. A second convex ring 361 is provided outside the piston column 360 in the air permeable cavity 341. A second spring 370 for driving the second convex ring 361 to drive the upper end of the piston column 360 to penetrate through the air permeable column 340 is sleeved on the piston column 360 in the air permeable cavity 341. An air cavity 362 with an upper end opening is provided in the piston column 360. Second air holes 363 are arranged along the circumferential direction of the side wall of the air cavity 362. The second spring 370 is used to drive the piston column 360 to move upward to seal the second air holes 363. The downward movement of the buffer rod 220 is used to squeeze the piston column 360 to move downward so that its lower end extends out of the air permeable column 340 to open the second air holes 363.

[0055] Through the structure in this embodiment, in the natural state, the second spring 370 is used to drive the second convex ring 361 to drive the piston column 360 to move upward, so that the second air holes 363 at its lower end cooperate with the side wall of the second blocking ring 350 to seal the second air holes 363. At this time, the air permeable component is closed, and no air convection can be formed at the buffer component 120, so that the mattress will not generate convection when not in use; when the user lies on the mattress, the buffer rod 220 moves downward to squeeze the piston column 360 to move downward, and then its lower end extends out of the second blocking ring 350, so that the second air holes 363 are opened, so that the air in the lower cavity 311b can be discharged through the air cavity 362 and the second air holes 363, automatically opening the air permeable components in all the buffer components where the user lies on the mattress, forming an air convection at the place where the user lies on the mattress, enabling the mattress to form air exchange at the place where the user lies, thereby improving the comfort of the user;

[0056] Among them, through the setting of the second blocking ring 350, the second convex ring 361 and the second spring 370, the disassembly and assembly of the piston column 360 in the air permeable column 340 are preferably realized.

[0057] Combined with Figure 4 andFigure 5 As shown, in this embodiment, a sliding groove 333 is provided at the lower end opening of the air guiding groove 332, and a first guiding inclined surface connecting the air guiding groove 332 is provided on the sliding groove 333;

[0058] A connecting ring 380 is threadedly connected in the lower cavity 311b. A guide rod 411 arranged along the axial direction of the air permeable column 340 is provided on the connecting ring 380 corresponding to the sliding groove 333. Sliding blocks 390 extending into the corresponding sliding grooves 333 are provided on the guide rods 411 through third springs 412. A first inclined surface 421 cooperating with the corresponding first guiding inclined surface is provided on the sliding blocks 390. When the buffer rod 220 moves downward, it is used to drive the first guiding inclined surface to squeeze the first inclined surface 421 to drive the sliding blocks 390 to move along the guide rods 411 towards the connecting ring 380;

[0059] The lower end of the buffer rod 220 extends into the air cavity 362. A convex block 510 extending out of the air permeable column 340 is provided on the second convex ring 361 corresponding to the sliding block 390. A second guiding inclined surface 511 is provided on the convex block 510; A driving block 422 extending to the corresponding convex block 510 is provided on the sliding block 390. A second inclined surface 423 for cooperating with the corresponding second guiding inclined surface 511 is provided on the driving block 422. When the sliding block 390 moves along the guide rod 411 towards the connecting ring 380, it is used to drive the second inclined surface 423 to squeeze the second guiding inclined surface 511 to drive the piston column 360 to move downward, realizing the opening of the second air hole 363.

[0060] Through the structure in this embodiment, when the buffer rod 220 moves downward, it can drive the sliding block 390 to move along the guide rod 411 towards the connecting ring 380 through the first guiding inclined surface, and under the action of the third spring 412, the sliding block 390 is moved into the corresponding air guiding groove 332. During this process, the second inclined surface 423 on the driving block 422 of the sliding block 390 is squeezed with the second guiding inclined surface 511 to drive the piston column 360 to move downward to realize the opening of the second air hole 363. Among them, since the air guiding groove 332 is arranged along the axial direction of the buffer rod 220, and the buffer rod 220 can extend into the air cavity 362, when the buffer rod 220 moves downward by a certain distance, the piston column 360 can be driven to move downward to open the air permeable component. At the same time, the extending length of the piston column 360 can be fixed, so that in actual use, when a user with a heavier weight lies on the mattress, the length of the buffer component 120 will not be too long, causing the first spring 160 to be unable to perform shock absorption and buffering on the mattress 100.

[0061] Combined with Figure 1 As shown, in this embodiment, a fan installation groove 107 is provided on the side wall of the base 130, and a fan (not shown in the figure) for blowing out the air flow in the adjustment groove 131 is installed in the fan installation groove 107.

[0062] Through the structure in this embodiment, the fan can blow out the air in the adjustment groove 131, thereby generating negative pressure in the adjustment groove 131, enabling the air outside the mattress to better enter the shock absorption groove 104 and enter the adjustment groove 131 through the buffer assembly 120, thereby preferably generating air convection and making the air exchange effect of the mattress better.

[0063] Combined with Figure 6 As shown, in this embodiment, the adjustment assembly 140 includes an adjustment column 600. An adjustment cavity 711 is provided in the adjustment column 600. A push rod 620 with its upper end extending out of the adjustment column 600 is provided in the adjustment cavity 711 through an adjustment member. The push rod 620 moves up and down in the adjustment cavity 711 to drive the adjustment plate 150 to move up and down.

[0064] Through the structure in this embodiment, it is preferably enabled that the user can drive the push rod 620 to move up and down through the adjustment member, thereby adjusting the lifting of the adjustment plate 150 and realizing the adjustment of the height of the mattress.

[0065] Combined with Figure 7 As shown, in this embodiment, a third plug ring 610 is provided with a thread at the lower end opening of the adjustment cavity 711;

[0066] The adjustment member includes a rotating column 720 rotatably provided in the adjustment cavity 711. The lower end of the rotating column 720 penetrates through the third plug ring 610. A thread cavity 721 for threadedly cooperating with the push rod 620 is provided at the upper end of the rotating column 720. An activity hole for the push rod 620 to pass through is provided at the upper end part of the adjustment cavity 711. A positioning chute 621 is provided on the outer wall of the push rod 620 along its axial direction. A positioning slider that slides in the positioning chute 621 is provided on the side wall of the activity hole.

[0067] In this embodiment, through the cooperative setting of the positioning slider and the positioning chute 621, the push rod 620 is restricted and cannot rotate circumferentially; among them, through the setting of the rotating column 720 and the thread cavity 721, when the user drives the rotating column 720 to rotate, the push rod 620 can be driven to move up and down, thereby preferably realizing the lifting adjustment of the adjustment plate 150;

[0068] Among them, through the setting of the third plug ring 610, the rotational installation of the rotating column 720 in the adjustment cavity 711 is preferably realized.

[0069] Among them, in order to facilitate the user to drive the rotation of the rotating column 720, a hexagonal nut groove 722 is provided at the lower end opening of the rotating column 720, enabling the user to preferably drive the rotation of the rotating column 720 through an internal hexagonal wrench, which is convenient for operation.

[0070] In this embodiment, the cushion body 100 and the adjusting cushion 110 are covered with a protective cloth (not shown in the figure). Through the arrangement of the protective cloth, a whole mattress is formed between the cushion body 100 and the adjusting cushion 110, which is convenient for users. Among them, in order to achieve better ventilation, the protective cloth is provided with holes corresponding to the ventilation holes 105 and the fans around the mattress.

[0071] Working principle: When the user uses the shock-absorbing device of the mattress, the buffer assembly 120 and the adjusting cushion 110 are assembled on the cushion body 100. Then, according to the required height of the mattress, the rotating column 720 is driven to rotate by an Allen wrench, driving the lifting rod 620 to move up and down, so as to realize the lifting adjustment of the adjusting plate 150, so that the height between the cushion body 100 and the adjusting cushion 110 meets the requirements. Then, the protective cloth is wrapped around the cushion body 100 and the adjusting cushion 110 to form a mattress. When the user lies on the mattress, the buffer rod 220 is driven to move down, and then the piston rod 360 is driven to move down, so that the second air hole 363 is opened. At this time, the fan works, which can preferably form air convection in the mattress where the user lies, making the ventilation effect of the mattress better.
