Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a shock-absorbing component, a control box, and a mattress. Background Technology

[0002] Existing mattresses include air cushions with internal bladders and a control box that regulates the air pressure within the bladders. The control box contains components such as an air pump and a solenoid valve assembly. During operation, the high-pressure gas generated by the air pump is distributed to each bladder via the solenoid valve assembly, allowing the bladders to adjust their firmness by changing the air pressure, thus providing comfortable support for the user. However, the air pump and solenoid valve assembly generate vibrations during operation, which are transmitted outwards and produce noise, potentially disturbing the user's sleep and affecting the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a shock-absorbing component, a control box, and a mattress, including a body with a spring disposed between a first connecting part and a second connecting part. This ensures a reliable connection between the first and second connecting parts and utilizes the deformation of the spring and the body to eliminate vibration, reduce noise, minimize the impact on the user's sleep, and improve the user experience.

[0004] This invention achieves its purpose through the following method: a shock-absorbing component includes a body spanning between a first connecting portion and a second connecting portion. A spring is sleeved in the middle section of the body, and the spring is clamped between the first and second connecting portions. The spring extends and retracts along the axis of the body, hindering the transmission of vibration between the first and second connecting portions. By placing the body between the first and second connecting portions and sleeved with the spring, the body ensures a reliable connection between the first and second connecting portions, preventing them from separating. Furthermore, the deformation of the spring and the body eliminates vibration and maintains the relative position between the first and second connecting portions, effectively reducing noise and minimizing the impact on the user's sleep, thus improving the user experience.

[0005] Preferably, the body is cylindrical, with an upper buckle at the top and a lower buckle at the bottom. The first connecting part is engaged with the upper buckle, and the second connecting part is engaged with the lower buckle, so that the spring is clamped and limited in the middle section of the body. The body is fastened to the second connecting part by the lower buckle and to the first connecting part by the upper buckle, thus restricting the spring to the section of the body between the upper and lower buckles. The cylindrical shape of the body facilitates the placement of the spring and provides guidance for the spring's expansion and contraction.

[0006] Preferably, the upper buckle is conical, with an annular upper limit surface formed at the periphery of its bottom surface. The first connecting portion has an upper through hole, through which the upper buckle passes and overlaps the upper end of the through hole via the upper limit surface. The upper buckle is wider at the bottom and narrower at the top, with frustoconical sidewalls. This design facilitates the upper buckle's deformation through the through hole and engagement with the first connecting portion, while also allowing the upper limit surface to abut against the first connecting portion, thus preventing the first connecting portion from detaching from the main body and improving connection reliability.

[0007] Preferably, the diameter of the middle section of the body is smaller than that of the upper through hole, and the outer diameter of the upper limit surface is larger than that of the upper through hole. This ensures that the upper through hole is fitted onto the middle section of the body after passing over the upper buckle, and also ensures that the upper buckle, after deformation and restoration, can abut against the periphery of the upper through hole through the upper limit surface, preventing the first connecting part from detaching from the body.

[0008] Preferably, the lower buckle includes two retaining rings offset at different heights on the bottom sidewall of the main body, forming an annular groove between the retaining rings. The second connecting part has a lower through hole, and the bottom of the main body is inserted into the lower through hole from top to bottom, so that the periphery of the lower through hole is engaged in the groove. There are two retaining rings, vertically separated, forming a groove between them. During installation, the lower through hole on the second connecting part spans one retaining ring and is engaged in the groove, ensuring a reliable connection between the main body and the second connecting part and preventing the second connecting part from detaching from the main body.

[0009] Preferably, the lower limit surface is formed on the periphery of the top surface of the lower buckle, and the spring is locked between the lower limit surface and the first connecting part. The lower limit surface is formed on the top surface of the retaining ring near the middle of the body, and the bottom end of the spring abuts against the lower limit surface to prevent the spring from falling off the body and to limit the spring.

[0010] Preferably, the body is a deformable and recoverable rubber component, and the spring is coaxially sleeved with the body. The body, through stretching, forms a preload that restricts the first connecting part and the second connecting part from moving away from each other, while the spring, through vertical compression, forms a preload that restricts the first connecting part and the second connecting part from moving closer to each other. Both the spring and the rubber body have deformable and recoverable properties, ensuring that the relative position between the first and second connecting parts remains fixed, thus providing fixation for both parts. Furthermore, their deformation and recovery properties can hinder vibration transmission, reducing noise by eliminating vibration between the first and second connecting parts. The spring sleeved on the body effectively improves the body's resistance to radial deformation and ensures that the body will not be compressed and deformed, improving recovery efficiency.

[0011] A control box includes a housing with an internal mounting cavity and a functional component disposed within the mounting cavity. The functional component is fixed within the mounting cavity by a vibration damping assembly. A first connecting portion is disposed on the functional component, and a second connecting portion is disposed on the inner wall of the mounting cavity to limit the transmission of vibrations generated by the functional component to the housing. The functional component is mounted within the housing by the vibration damping assembly, which not only fixes the functional component, ensuring it remains in a preset position and does not contact adjacent components, thus ensuring independent and stable operation, but also effectively blocks vibration transmission, thereby reducing the operating noise of the functional component.

[0012] Preferably, the functional component is an air pump. The first connecting part includes a connecting plate and a collar disposed on the connecting plate. The air pump is inserted into the collar and fixedly connected to the connecting plate. The connecting plate is connected to the air pump through the collar. The air pump is fixedly connected to the mounting cavity through a shock-absorbing component, ensuring that vibration is not transmitted to the housing and effectively reducing noise.

[0013] Preferably, the functional component is a solenoid valve assembly, which is installed inside the housing via a shock-absorbing component to prevent the vibration generated during the operation of the solenoid valve assembly from being transmitted outward.

[0014] Preferably, the functional component is installed and fixed by at least four sets of shock-absorbing components. The shock-absorbing components are distributed in a way that not only improves the efficiency of disassembly and assembly by limiting the number of shock-absorbing components, but also eliminates the vibration transmitted in all directions by each shock-absorbing component, thereby ensuring that the functional component is stably supported and fixed, and preventing the functional component from shifting or tilting due to vibration.

[0015] A mattress includes an air cushion with internal bladders and a control box, the control box regulating the air pressure within the bladders. The control box regulates the air pressure within the bladders, thereby allowing the firmness of the air cushion to be adjusted to meet the diverse needs of users.

[0016] The beneficial effects of this utility model are as follows: A body is provided between the first connecting part and the second connecting part, and a spring is sleeved on the body. The body ensures a reliable connection between the first connecting part and the second connecting part and prevents them from separating. The deformation of the spring and the body also eliminates vibration and maintains the relative position between the first connecting part and the second connecting part, effectively reducing noise and minimizing the impact on the user's sleep, thus improving the user experience.

Detailed Implementation

[0025] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1:

[0027] like Figure 1 The shock-absorbing component 19 shown includes a body 3 spanning between a first connecting portion 1 and a second connecting portion 2. A spring 4 is sleeved in the middle of the body 3, and the spring 4 is clamped between the first connecting portion 1 and the second connecting portion 2. The spring 4 extends and retracts along the axis of the body 3 and impedes the transmission of vibration between the first connecting portion 1 and the second connecting portion 2. The body 3, with the spring 4 sleeved on it, ensures a reliable connection between the first connecting portion 1 and the second connecting portion 2, preventing separation. Furthermore, the deformation of the spring 4 and the body 3 eliminates vibration and maintains the relative position between the first connecting portion 1 and the second connecting portion 2, effectively reducing noise and minimizing the impact on the user's sleep, thus improving the user experience.

[0028] In this embodiment, the body 3 is cylindrical (e.g., ...). Figure 2As shown, the top of the body 3 is provided with an upper buckle 5, and the bottom of the body 3 is provided with a lower buckle. The first connecting part 1 is fastened to the upper buckle 5, and the second connecting part 2 is fastened to the lower buckle, so that the spring 4 is clamped and limited on the middle section of the body 3. The body 3 is a one-piece structure. The top and bottom of the body 3 are respectively provided with an upper buckle 5 and a lower buckle. The spring 4 is sleeved on the middle section of the body 3. The two ends of the body 3 are fastened and fixed to the first connecting part 1 and the second connecting part 2 by the upper buckle 5 and the lower buckle, respectively.

[0029] In this embodiment, the body 3 is a deformable and repositionable rubber component. The spring 4 is coaxially sleeved with the body 3. The body 3 forms a preload force by stretching to restrict the first connecting part 1 and the second connecting part 2 from moving away. The spring 4 forms a preload force by vertical compression to restrict the first connecting part 1 and the second connecting part 2 from moving closer to each other. Specifically, the first connecting part 1 is fastened to the upper buckle 5 and acts as an upper limit for the spring 4. The second connecting part 2 is fastened to the lower buckle and acts as a lower limit for the spring 4. The spring 4 is sleeved on the middle section of the body 3 and is vertically limited by the first connecting part 1 and the lower buckle. The body 3 not only connects and positions the first connecting part 1 and the second connecting part 2, but also effectively eliminates the vibration transmitted between the first connecting part 1 and the second connecting part 2. The spring 4 not only shapes the middle section of the body 3 to prevent bending, but also effectively eliminates the vibration transmitted between the first connecting part 1 and the second connecting part 2.

[0030] In this embodiment, the lower buckle has a lower limiting surface 11 formed on its top periphery, and the spring 4 is engaged between the lower limiting surface 11 and the first connecting part 1. The upper buckle 5 on the top of the body 3 passes through the upper through hole 7 from bottom to top and abuts against the periphery of the upper port of the lower through hole 10 through the upper limiting surface 6. The lower through hole 10 spans the lower retaining ring 8 and is embedded in the buckle groove 9 through its periphery. The spring 4 is vertically clamped between the periphery of the lower port of the upper through hole 7 and the lower limiting surface 11 to prevent the middle section of the body 3 from being compressed and deformed.

[0031] In this embodiment, the upper buckle 5 is conical, and the bottom periphery of the upper buckle 5 forms an annular upper limit surface 6. The first connecting part 1 is provided with an upper through hole 7. The upper buckle 5 passes through the upper through hole 7 from bottom to top and overlaps the upper port periphery of the upper through hole 7 through the upper limit surface 6. The upper buckle 5 is conical and has inclined sidewalls, which can convert the vertical force of the upper buckle 5 passing through the upper through hole 7 into a radial force that drives the upper buckle 5 to retract radially, so that the upper buckle 5 can return to its original shape after retracting and passing through the upper through hole 7.

[0032] In this embodiment, the diameter of the middle section of the body 3 is smaller than that of the upper through hole 7, and the outer diameter of the upper limit surface 6 is larger than that of the upper through hole 7. The diameter of the upper through hole 7 is between the diameter of the middle section of the body 3 and the outer diameter of the upper limit surface 6. This facilitates the upper through hole 7 being fitted onto the middle section of the body 3, and also ensures that the upper limit surface 6 can abut against the periphery of the upper port of the upper through hole 7, thereby acting as a stop and limit for the first connecting part 1. This ensures that the upper limit surface 6 can limit the spring 4 through the first connecting part 1.

[0033] In this embodiment, the lower buckle includes two retaining rings 8 offset at different heights on the bottom sidewall of the main body 3, forming an annular buckle groove 9 between the retaining rings 8. The second connecting part 2 is provided with a lower through hole 10. The bottom of the main body 3 is inserted into the lower through hole 10 from top to bottom, so that the periphery of the lower through hole 10 is engaged in the buckle groove 9. The upper retaining ring 8 near the middle section of the main body 3 can not only cooperate with the lower retaining ring 8 to clamp the second connecting part 2, but also form a lower limiting surface 11 for supporting the spring 4 through its top surface. The retaining rings 8 and the main body 3 are integrally formed, which is convenient for processing and ensures the structural strength of the lower buckle. The connection reliability is improved by clamping the second connecting part 2.

[0034] In this embodiment, the retaining rings 8 are arranged along the periphery of the bottom side wall of the body 3, and the retaining rings 8 are parallel to each other. The distance between the retaining rings 8 matches the periphery thickness of the lower through hole 10, effectively eliminating the gap between the buckle groove 9 and the second connecting part 2, and preventing relative movement between the two.

[0035] Example 2:

[0036] Compared to Embodiment 1, this embodiment provides a control box 16.

[0037] like Figure 3 The control box 16 shown includes a housing 12 with an internal mounting cavity and functional components disposed within the mounting cavity. The functional components are fixed within the mounting cavity by a shock-absorbing assembly 19. A first connecting portion 1 is disposed on the functional component, and a second connecting portion 2 is disposed on the inner wall of the mounting cavity to limit the transmission of vibrations generated by the functional components to the housing 12. The vibrations generated by the operation of the functional components can be eliminated by the shock-absorbing assembly 19, effectively preventing the housing 12 from generating noise due to vibrations received from the functional components, thereby improving the user's sleep quality and enhancing the user experience.

[0038] In this embodiment, the functional component is an air pump 13, which generates high-pressure air to increase the air pressure inside the bladder. The first connecting part 1 includes a connecting plate 18 and a collar 15 disposed on the connecting plate 18 (e.g., Figure 4 As shown in the diagram, the air pump 13 is inserted into the collar 15 and fixedly connected to the connecting plate 18. During installation, the collar 15 is tightly fastened to the air pump 13 to ensure a secure connection between the connecting plate 18 and the air pump 13 (as shown in the diagram). Figure 5As shown, the connecting plate 18 is fixedly connected to the second connecting part 2 provided on the housing 12 via the body 3, and the deformation and reset performance of the body 3 and the spring 4 is used to counteract the noise generated by the operation of the air pump 13.

[0039] In this embodiment, the functional component may also be a solenoid valve assembly 14, which is mounted on the housing 12 via a shock-absorbing component 19 (e.g., Figure 6 As shown, the effective blocking of the vibration generated by the solenoid valve assembly 14 from being transmitted to the housing 12 should also be considered as a specific implementation of this embodiment.

[0040] In this embodiment, the functional component is installed and fixed by at least four sets of shock-absorbing components 19. The shock-absorbing components 19 are distributed to ensure that the shock-absorbing components 19 can stably support the functional component and prevent the functional component from tilting or shifting. They can also effectively share the vibration, thereby improving the shock absorption and noise reduction effect.

[0041] The other structures and effects of the shock absorption component 19 described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0042] Example 3:

[0043] Compared to Embodiment 2, this embodiment provides a mattress.

[0044] like Figure 7 The mattress shown comprises an air cushion 17 with an internal bladder and a control box 16, wherein the control box 16 regulates the air pressure within the bladder. The control box 16 can adjust the air pressure within the bladder; when the air pressure increases, the firmness of the air cushion 17 increases, and vice versa. This allows the firmness of the air cushion 17 to be freely adjusted according to user needs.

[0045] The other structures and effects of the control box 16 described in this embodiment are the same as those in Embodiment 2, and will not be repeated here.
