Description

Technical Field

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

[0002] Existing mattresses include a mattress body with internal airbags and a control box for adjusting the air pressure within the airbags. The control box includes a housing, a suspension assembly housed within the housing, and functional components mounted on the suspension assembly. The suspension assembly includes a cantilever and a suspension frame. The suspension frame is connected to the cantilever via shock-absorbing feet. Specifically, the cantilever is fixed within the housing, and the top and bottom of the shock-absorbing feet are fixed to the suspension frame and cantilever, respectively, ensuring a fixed horizontal position between the cantilever and suspension frame. The shock-absorbing feet are normally in a compressed state, supporting the weight of the suspension frame and offsetting vibrations through their own deformation. When the control box accidentally flips over, the vertical relative positions of the suspension frame and cantilever shift, causing the suspension frame to be suspended below the suspension frame via the shock-absorbing feet. The shock-absorbing feet change from a compressed state to a stretched state, potentially leading to damage or even breakage due to overstretching. This shortens the lifespan of the shock-absorbing feet, increases maintenance costs, and negatively impacts the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a control box and mattress with a limiting component. The limiting component is set above the suspension to limit the suspension and ensure that the suspension does not move too far away from the cantilever, preventing the shock-absorbing feet from being damaged or broken due to excessive stretching, effectively extending the service life of the shock-absorbing feet and improving the user experience.

[0004] This utility model is achieved through the following method: a control box with a limiting component, comprising a housing, a suspension assembly disposed within the housing, and functional components mounted on the suspension assembly. The suspension assembly includes a cantilever and a suspension frame. The suspension frame is fixed above the cantilever via a shock-absorbing foot. A limiting component is provided on the cantilever, suspended above the suspension frame with a pre-existing clearance between them. The suspension frame shifts upward and is resisted by the limiting component, thereby reducing the tensile deformation of the shock-absorbing foot. The limiting component above the suspension frame limits its movement, ensuring that the suspension does not move excessively away from the cantilever, preventing the shock-absorbing foot from breaking due to excessive stretching, effectively extending the service life of the shock-absorbing foot. It also provides a clearance for the suspension frame to move upward, ensuring that the suspension frame and the limiting component remain separated, preventing frequent impacts between the limiting component and the suspension, and improving the user experience.

[0005] Preferably, the limiting member includes a long, narrow limiting portion suspended above the suspension and connecting portions at both ends of the limiting portion. The connecting portions are fixed to the cantilever, thus suspending the limiting portion above the suspension. The limiting member is fixed to the cantilever and vertically limits the suspension, ensuring that the suspension can only move vertically between the cantilever and the limiting portion, thereby limiting the vertical extension and retraction of the shock absorber and protecting it.

[0006] Preferably, the connecting portion is L-shaped, including a fixed section that is fitted and fixed to the cantilever and a support section spanning between the fixed section and the limiting section. The length of the support section is greater than the suspension height to create a movable gap between the limiting section and the top surface of the suspension. The fixed section is fitted to the top surface of the corresponding end of the cantilever and fixed by fasteners. The support section connects the limiting section and the fixed section, ensuring that the distance between the limiting section and the cantilever remains constant, thereby improving the positioning reliability of the suspension. The movable gap between the limiting section and the top surface of the suspension prevents direct contact between the limiting section and the suspension, reserving space for the suspension to move, and also effectively reduces the stretching amplitude of the shock absorber foot, thus protecting the shock absorber foot.

[0007] Preferably, the connecting part is formed by bending the end edge of the limiting part, and the vertical projections of the connecting part and the suspension are offset from each other. The limiting part is integrally machined, which is convenient for processing and has good structural strength, effectively improving the limiting reliability of the limiting part. The vertical projection offset between the connecting part and the suspension ensures that the connecting part does not hinder the lifting and lowering movement of the suspension, and also facilitates the connection between the connecting part and the cantilever.

[0008] Preferably, the suspension is fixed to the corresponding cantilever on both sides by at least two shock-absorbing feet. By setting multiple shock-absorbing feet, the suspension attitude is maintained, ensuring that the suspension is stably installed on the cantilever.

[0009] Preferably, the functional component is an air pump assembly used to produce high-pressure air and regulate the air pressure inside the airbag.

[0010] Preferably, the functional component is a solenoid valve assembly, used to switch the airbags connected to the control box, so that the air pressure in each airbag can be adjusted independently.

[0011] As a preferred option, the functional component is a buffer air box, which is used to buffer the high-pressure airflow, thereby reducing noise.

[0012] Preferably, both ends of the cantilever are fixed to the inner wall of the housing. Fixed connection of both ends of the cantilever to the inner wall of the housing ensures that the suspension is fixed in position within the housing, guaranteeing that the functional components are suspended below the suspension, preventing the functional components from contacting the housing and transmitting vibrations outwards.

[0013] Preferably, the two ends of the shock absorber foot are fixedly connected to the cantilever and the suspension respectively, so that the shock absorber foot is clamped between the cantilever and the suspension and hinders the transmission of vibration. The top end of the shock absorber foot is fixedly connected to the suspension, and the bottom end is fixedly connected to the cantilever, which can not only effectively improve the shock absorption effect, but also ensure that the relative position between the cantilever and the suspension is fixed.

[0014] Preferably, the bottom surface of the shock-absorbing foot is provided with a screw hole, and a through hole is opened in the middle of the cantilever. The fastener passes through the through hole from bottom to top and is screwed into the screw hole to fix the bottom of the shock-absorbing foot to the cantilever. The fastener passes through the through hole and is screwed into the screw hole to lock it in place, ensuring that the bottom of the shock-absorbing foot is firmly connected to the cantilever and playing a positioning role for the shock-absorbing foot.

[0015] Preferably, the top surface of the shock absorber foot is provided with a vertically placed stud, and the suspension has a threaded mounting hole. The stud is screwed into the mounting hole to fix the top of the shock absorber foot to the suspension. The stud is inserted into the mounting hole and screwed in to lock it in place, thus fixing the top of the shock absorber foot to the suspension and providing support for the suspension.

[0016] Preferably, the lower end of the mounting hole is flared to form a downward-facing annular groove. The diameter of the annular groove is larger than the diameter of the shock absorber foot. The diameter of the mounting hole matches the diameter of the stud. The stud is inserted into the mounting hole and abuts against the top wall of the annular groove through the top surface of the shock absorber foot. The annular groove allows the top of the shock absorber foot to be inserted and positioned, providing vertical support and horizontal restraint for the suspension.

[0017] Preferably, the top end of the stud is exposed on the top surface of the suspension, and the limiting member has a limiting hole for the top end of the stud to pass through, thereby limiting the horizontal displacement of the suspension. The top end of the stud is inserted into the limiting hole, so that the top end of the stud can abut against the inner wall of the limiting hole and limit the horizontal displacement of the top of the shock absorber, thereby playing a role in horizontally limiting the suspension.

[0018] A mattress includes a mattress body, air bladders within the mattress body, and a control box. The control box is connected to the air bladders to allow for adjustable air pressure within the air bladders. The control box adjusts the air pressure within each air bladder and uses limiting elements to prevent the suspension from pulling on the shock-absorbing feet due to excessive deviation from the cantilever.

[0019] The beneficial effects of this utility model are as follows: By setting a limiting component above the suspension, the suspension is limited, which not only ensures that the suspension does not move too far away from the cantilever, but also prevents the shock absorber foot from being damaged or broken due to excessive stretching, effectively extending the service life of the shock absorber foot. In addition, a clearance is reserved for the upward movement of the suspension, ensuring that the suspension and the limiting component remain separated, preventing frequent collisions between the limiting component and the suspension, and improving the user experience.

Detailed Implementation

[0027] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1:

[0029] This embodiment provides a control box.

[0030] like Figure 1 The control box shown includes a housing 1, a suspension assembly housed within the housing 1, and functional components mounted on the suspension assembly. The suspension assembly includes a cantilever 2 and a suspension 3. The suspension 3 is fixed above the cantilever 2 via a shock-absorbing foot 4. A limiting member 5 is provided on the cantilever 2. The limiting member 5 is suspended above the suspension 3 with a pre-existing clearance 6 between them. The suspension 3 shifts upward and is resisted by the limiting member 5 to reduce the tensile deformation of the shock-absorbing foot 4. The limiting member 5 above the suspension 3 limits its movement, ensuring that the suspension 3 does not move excessively away from the cantilever 2, preventing the shock-absorbing foot 4 from breaking due to excessive stretching, effectively extending the service life of the shock-absorbing foot 4. The pre-existing clearance 6 allows the suspension 3 to move upward, ensuring that the suspension 3 remains separated from the limiting member 5, preventing frequent impacts between the limiting member 5 and the suspension 3, and improving the user experience.

[0031] In this embodiment, the limiting member 5 includes a long, narrow limiting part 7 suspended above the suspension 3 and connecting parts (such as...) provided at both ends of the limiting part 7. Figure 5As shown), the connecting part is fixedly connected to the cantilever 2, causing the limiting part 7 to be suspended above the suspension 3. The limiting member 5 is fixedly connected to the end of the cantilever 2 through the connecting part, so that the middle part of the cantilever 2 and the limiting part 7 are respectively located below and above the suspension 3 (as shown). Figure 4 As shown, it limits the vertical displacement of the cantilever 2, ensuring that the shock absorber 4 will not be damaged or broken when the control box is flipped because the suspension 3 pulls it away from the cantilever 2. It not only protects the shock absorber 4, but also limits and protects the suspension 3.

[0032] During use, the vibrations generated by the operation of the functional components are reduced and amplified by the damping band before being transmitted to the suspension 3. The vibrations on the suspension 3 are then offset by the deformation of the damping feet 4, effectively preventing the vibrations generated by the functional components from being transmitted to the housing 1 and generating noise. Because a movable gap 6 is reserved between the limiting part 7 and the top surface of the suspension 3, the suspension 3 will not contact the limiting part 5 during vibration, thus effectively preventing the suspension 3 from contacting the limiting part 5 and transmitting vibrations. The damping feet 4 are always in a compressed state. When the control box is accidentally overturned during transportation or use, the suspension 3 will be suspended below the cantilever 2, causing the damping feet 4 to change from a compressed state to a stretched state. The suspension 3 falls to the movable gap 6 height and overlaps the limiting part 5. The limiting part 5 supports the suspension 3, ensuring that the distance between the suspension 3 and the cantilever 2 remains within a preset range. This ensures that the damping feet 4 will not break due to excessive stretching and that the damping feet 4 can still be used after the control box is overturned and reset, effectively extending the service life of the damping feet 4.

[0033] In this embodiment, the connecting part is L-shaped, including a fixed section 8 that is fitted and fixed to the cantilever 2 and a support section 9 that spans between the fixed section 8 and the limiting part 7. The length of the support section 9 is greater than the height of the suspension 3, so as to form a movable gap 6 between the limiting part 7 and the top surface of the suspension 3. Both ends of the limiting member 5 are formed with connecting parts to ensure that both ends of the limiting member 5 can be fixed to the cantilever 2 and to ensure that the limiting part 7 is maintained in a preset position. This can effectively maintain the movable gap 6 and effectively support the suspension 3, thereby protecting the shock absorber 4. The connecting part is formed by bending the end edge of the limiting part 7. The vertical projections of the connecting part and the suspension 3 are staggered to ensure that the connecting part is vertically exposed, which facilitates the disassembly and assembly of the connecting part and the cantilever 2.

[0034] In this embodiment, the suspension 3 is fixed to the corresponding cantilever 2 on both sides by at least two damping feet 4. The suspension 3 is fixed to the housing 1 on both sides by the corresponding cantilever 2, and the two ends of the cantilever 2 are fixed to the inner wall of the housing 1. This allows the suspension 3 to be mounted on the corresponding cantilever 2 by at least four damping feet 4, which effectively improves the attitude stability of the suspension 3, effectively distributes the weight, and facilitates the damping feet 4 to counteract vibration, thereby improving the shock absorption and noise reduction effect. In addition, the number of damping feet 4 between the suspension 3 and the cantilever 2 can be adjusted as needed to meet the support and shock absorption requirements, and all such adjustments should be considered as specific implementations of this embodiment.

[0035] In this embodiment, the functional components are air pump assembly 10, solenoid valve assembly 11, buffer air box 12, etc. (e.g.) Figure 3 As shown, the corresponding functions are achieved by configuring various functional components, and all of these should be regarded as specific implementation methods of this embodiment.

[0036] In this embodiment, the two ends of the shock-absorbing foot 4 are respectively fixedly connected to the cantilever 2 and the suspension 3 (e.g., Figure 2 As shown), the damping foot 4 is clamped between the cantilever 2 and the suspension 3 to impede the transmission of vibration. The top of the damping foot 4 is fixed to the suspension 3, and the bottom is fixed to the cantilever 2, which not only ensures that the suspension 3 and the cantilever 2 are fixed by the damping foot 4, but also uses the damping foot 4 to impede the transmission of vibration.

[0037] In this embodiment, the bottom surface of the shock-absorbing foot 4 is provided with a screw hole 13, and the middle part of the cantilever 2 is provided with a through hole 14. The fastener passes through the through hole 14 from bottom to top and is screwed into the screw hole 13 so that the bottom of the shock-absorbing foot 4 is fixedly connected to the cantilever 2, ensuring that the cantilever 2 and the shock-absorbing foot 4 are firmly connected.

[0038] In this embodiment, the top surface of the shock absorber 4 is provided with a vertically placed stud 15, and the suspension 3 is provided with a threaded mounting hole 16. The stud 15 is screwed into the mounting hole 16 to fix the top of the shock absorber 4 to the suspension 3. The lower end of the mounting hole 16 is flared to form a downward-facing exposed annular groove 17. The diameter of the annular groove 17 is larger than the diameter of the shock absorber 4, and the diameter of the mounting hole 16 matches the diameter of the stud 15. During installation, the top of the shock absorber 4 is inserted into the annular groove 17 and its top wall abuts against the top wall of the annular groove 17. The stud 15 passes through the annular groove 17 and is inserted into the mounting hole 16 and then screwed in and locked. The top surface of the shock absorber 4 abuts against the top wall of the annular groove 17, which serves to support the suspension 3. The top side wall of the shock absorber 4 abuts against the side wall of the annular groove 17, which serves to limit horizontal movement. The stud 15 is screwed into the mounting hole 16 to prevent the shock absorber 4 from detaching from the suspension 3.

[0039] In this embodiment, the top end of the stud 15 is exposed on the top surface of the suspension 3. The limiting member 5 has a limiting hole 18 through which the top end of the stud 15 passes to limit the horizontal displacement of the suspension 3. The top end of the stud 15 extends upward and vertically through the limiting hole 18, so that the side wall of the stud 15 can abut against the inner wall of the limiting hole 18, and prevents horizontal displacement between the limiting member 5 and the shock absorber 4.

[0040] Example 2:

[0041] Compared to Embodiment 1, this embodiment provides a mattress.

[0042] like Figure 6 The mattress shown includes a mattress body, airbags 19 within the mattress body, and a control box. The control box is connected to the airbags 19 to allow for adjustable air pressure within the airbags 19. The control box adjusts the air pressure within each airbag 19 and uses a limiting member 5 to prevent the suspension 3 from pulling on the shock-absorbing feet 4 due to excessive deviation from the cantilever 2.

[0043] The other structures and effects of the control box described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.
