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 good limiting effect. The lower and upper cantilever arms clamp the suspension through shock-absorbing feet, limiting the suspension and preventing the shock-absorbing feet from being damaged or broken due to excessive stretching. This effectively extends the service life of the shock-absorbing feet and improves the user experience.

[0004] This utility model achieves its purpose through the following method: a control box with good limiting effect includes a housing, a suspension assembly disposed within the housing, and functional components mounted on the suspension assembly. The suspension assembly includes a lower cantilever, a suspension frame, and an upper cantilever. The upper cantilever, suspension frame, and lower cantilever are arranged sequentially from top to bottom and connected by shock-absorbing feet. The suspension frame is clamped between the upper and lower cantilever arms to limit vertical displacement of the suspension. The suspension frame is clamped between the upper and lower cantilever arms, and both the upper and lower cantilever arms are connected to the suspension frame and the lower cantilever arm to the suspension frame via shock-absorbing feet. This limits the suspension's movement, ensuring that it does not experience excessive vertical displacement and preventing the shock-absorbing feet from breaking due to excessive stretching. This effectively extends the service life of the shock-absorbing feet and improves the user experience.

[0005] Preferably, the shock-absorbing foot includes a lower foot positioned between the lower cantilever and the suspension, and an upper foot positioned between the suspension and the upper cantilever, so that the suspension is clamped and positioned between the lower and upper cantilever. The lower cantilever and the suspension are fixedly connected by the lower foot, which supports the suspension when the control box is normally positioned. At this time, the upper foot is located above the cantilever, effectively preventing the upper foot from being damaged or broken due to excessive stretching. The upper cantilever and the suspension are fixedly connected by the upper support foot, which supports the suspension when the control box is flipped. At this time, the lower foot is located above the suspension, effectively preventing the lower foot from being damaged or broken due to excessive stretching.

[0006] Preferably, both the upper and lower feet are vertically oriented, providing tension and support to the suspension. Both the upper and lower feet vertically support the suspension and can withstand tensile forces within a suitable range, ensuring the suspension is vertically positioned. When the control box is aligned or flipped, the upper and lower feet are in a stretched or compressed state, respectively, working together to vertically limit the suspension and prevent damage to the upper and lower feet.

[0007] Preferably, there are at least two upper feet arranged symmetrically, and at least three lower feet spaced apart. Since the control box is in a centered position for extended periods, the lower feet will consistently support the suspension; therefore, a larger number of lower feet ensures reliable suspension support. The upper feet only provide support when the control box is flipped over; due to their lower frequency of use, fewer upper feet are used to provide emergency suspension support.

[0008] Preferably, the vertical projections of the upper and lower feet are staggered and equidistant. The upper feet are positioned on the top surface of the suspension, and the lower feet are equidistant on the bottom surface of the suspension. This ensures that all areas of the suspension are effectively supported, and also facilitates the connection between the suspension and the upper and lower feet, making disassembly and maintenance convenient.

[0009] Preferably, the fixed end of the shock-absorbing foot is provided with a screw hole, and through holes are provided on both the lower and upper cantilever arms. Fasteners pass through the through holes and are screwed into the corresponding screw holes to fix the shock-absorbing foot in place. The fasteners pass through the through holes and are screwed into the corresponding screw holes to lock them in place, so that the fixed end of the shock-absorbing foot is fixed to the corresponding upper or lower cantilever arm.

[0010] Preferably, the movable end 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 shock absorber foot to the suspension. The stud is inserted into the mounting hole and screwed in to lock it in place, ensuring that the movable end of the shock absorber foot is fixed to the suspension and effectively counteracts vibrations from the suspension.

[0011] Preferably, the mounting hole facing the corresponding shock absorber foot has an exposed annular groove formed by flaring. 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 end face of the shock absorber foot. The annular groove allows the movable end of the shock absorber foot to be inserted and positioned, providing vertical support and horizontal limiting for the suspension.

[0012] Preferably, the upper cantilever includes a long, narrow limiting portion suspended above the suspension and connecting portions at both ends of the limiting portion. The connecting portions are fixedly connected to the lower cantilever, such that the limiting portion is positioned above the lower cantilever and encloses an assembly space for the suspension. The upper and lower cantilever are fixedly connected, vertically limiting the suspension and ensuring that the suspension can only move vertically between the lower and upper cantilever, thereby limiting the vertical extension and retraction of the shock absorber and protecting the shock absorber.

[0013] Preferably, the connecting portion is L-shaped, including a fixed section that is fitted and fixed to the lower cantilever and a support section that spans between the fixed section and the limiting section. The length of the support section is greater than the suspension height, so that a clearance is provided between the limiting section, the suspension, and the lower cantilever. The fixed section is fitted to the top surface of the corresponding end of the lower 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 lower cantilever remains constant, thereby improving the positioning reliability of the suspension.

[0014] Preferably, the functional component is an air pump assembly used to produce high-pressure air and regulate the air pressure inside the airbag.

[0015] 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.

[0016] As a preferred option, the functional component is a buffer air box, which is used to buffer the high-pressure airflow, thereby reducing noise.

[0017] Preferably, both ends of the lower cantilever are fixed to the inner wall of the housing. The fixed connection of both ends of the lower 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.

[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: the suspension is clamped between the upper and lower suspension arms, and the upper suspension arm and the suspension are connected by shock absorber feet, which limit the suspension and ensure that the suspension will not deviate excessively vertically. This prevents the shock absorber feet from being damaged or broken due to excessive stretching, effectively extends the service life of the shock absorber feet, and improves the user experience.

[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 and 2The control box shown includes a housing 1, a suspension assembly disposed within the housing 1, and functional components mounted on the suspension assembly. The suspension assembly includes a lower cantilever 2, a suspension 3, and an upper cantilever 5. The upper cantilever 5, suspension 3, and lower cantilever 2 are arranged sequentially from top to bottom and connected by shock-absorbing feet. The suspension 3 is clamped between the upper cantilever 5 and the lower cantilever 2 to limit the vertical offset of the suspension 3. The suspension 3 is clamped between the upper cantilever 5 and the lower cantilever 2, and the upper cantilever 5 and the suspension 3, as well as the lower cantilever 2 and the suspension 3, are connected by shock-absorbing feet to limit the suspension 3, ensuring that the suspension 3 does not experience excessive vertical offset, preventing the shock-absorbing feet from breaking due to excessive stretching, effectively extending the service life of the shock-absorbing feet, and improving the user experience.

[0031] In this embodiment, the shock absorber includes a lower foot 6 positioned between the lower cantilever 2 and the suspension 3, and an upper foot 4 positioned between the suspension 3 and the upper cantilever 5, so that the suspension 3 is clamped and positioned between the lower cantilever 2 and the upper cantilever 5. The two ends of the upper foot 4 are fixedly connected to the upper cantilever 5 and the suspension 3, respectively, and the two ends of the lower foot 6 are fixedly connected to the lower cantilever 2 and the suspension 3, respectively, so that the suspension 3 is clamped between the upper cantilever 5 and the lower cantilever 2 (e.g., ...). Figure 5 (As shown). The upper cantilever 5, suspension 3, and lower cantilever 2 are arranged sequentially from top to bottom. The upper cantilever 5 and suspension 3 are connected by an upper foot 4, and the lower cantilever 2 and suspension 3 are connected by a lower foot 6.

[0032] When in use, the control box is in the rectified position, with the upper suspension arm 5 and the upper foot 4 both located above the suspension 3, and the lower suspension arm 2 and the lower foot 6 located below the suspension 3. The weight of the suspension 3 is transferred to the lower suspension arm 2 through the lower foot 6. The upper suspension arm 5 pulls the suspension 3 upward through the upper foot 4 to ensure that the suspension 3 is vertically positioned and to protect the upper foot 4, preventing damage due to excessive stretching. The upper foot 4 and the lower foot 6 use deformation to counteract the vibration of the suspension 3. When the control box is in the flipped position, the upper cantilever 5 and the upper foot 4 are located below the suspension 3, and the lower cantilever 2 and the lower foot 6 are located above the suspension 3. The weight of the suspension 3 is transferred downward to the upper cantilever 5 through the upper foot 4, and the lower cantilever 2 pulls the suspension 3 upward through the lower foot 6 to ensure that the suspension 3 is vertically positioned and to protect the lower foot 6, preventing the lower foot 6 from being damaged due to excessive stretching. This ensures that the shock absorber foot can still be used after the control box is flipped and reset, effectively extending the service life of the shock absorber foot.

[0033] In this embodiment, both the upper foot 4 and the lower foot 6 are vertically oriented. The upper foot 4 and the lower foot 6 respectively pull and support the suspension 3, ensuring that the control box is vertically supported by the shock-absorbing foot located below the suspension 3 when it is in a normal or flipped position, thus protecting the shock-absorbing foot located above the suspension 3. The vertical projections of the upper foot 4 and the lower foot 6 are staggered and equidistant, ensuring that the suspension 3 is stably supported and providing installation space for each shock-absorbing foot through the staggered arrangement.

[0034] In this embodiment, the two sides of the suspension 3 are respectively clamped and positioned by the corresponding upper cantilever 5 and lower cantilever 2. Each side of the cantilever is provided with multiple upper feet 4 and lower feet 6. Specifically, there are at least two upper feet 4 arranged symmetrically, and at least three lower feet 6 arranged at intervals, which ensures that the suspension 3 can be stably supported and effectively disperses the force, thus protecting each shock absorber foot.

[0035] In this embodiment, the fixed end of the shock-absorbing foot is provided with a screw hole 13, and through holes 14 are provided on both the lower cantilever 2 and the upper cantilever 5. Fasteners pass through the through holes 14 and are screwed into the corresponding screw holes 13 so that the shock-absorbing foot is fixedly positioned, ensuring that both the upper cantilever 5 and the lower cantilever 2 can be firmly connected to the fixed end of the shock-absorbing foot.

[0036] In this embodiment, the movable end of the shock absorber foot 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 shock absorber foot to the suspension 3. The mounting hole 16 is flared at the port of the corresponding shock absorber foot to form an exposed annular groove 17. The diameter of the annular groove 17 is larger than the diameter of the shock absorber foot. The diameter of the mounting hole 16 matches the diameter of the stud 15. The stud 15 is inserted into the mounting hole 16 and abuts against the top wall of the annular groove 17 through the end face of the shock absorber foot. During installation, the movable end of the shock absorber foot is inserted into the annular groove 17 and abuts against the top wall of the annular groove 17 through its top wall. The stud 15 passes through the annular groove 17 and is inserted into the mounting hole 16 and then screwed in and locked. The end face of the movable end of the shock absorber foot abuts against the top wall of the annular groove 17, which serves to support the suspension 3. The side wall of the movable end of the shock absorber foot abuts against the side wall of the annular groove 17, which serves to limit the horizontal movement. The stud 15 is screwed into the mounting hole 16 to prevent the shock absorber foot from detaching from the suspension 3.

[0037] In this embodiment, the two ends of the lower cantilever 2 are fixed to the inner wall of the housing 1 to ensure that the relative position between the lower cantilever 2 and the upper cantilever 5 is fixed. The upper cantilever 5 includes a long strip-shaped limiting part 7 suspended above the suspension 3 and connecting parts (such as...) provided at both ends of the limiting part 7. Figure 4As shown, the connecting part is fixedly connected to the lower cantilever 2, and the limiting part 7 is positioned above the lower cantilever 2, enclosing an assembly space for the suspension 3 to be suspended. The connecting part is L-shaped and includes a fixed section 8 that is fitted and fixedly connected to the lower 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 that a clearance is reserved between the limiting part 7, the suspension 3, and the lower cantilever 2. Connecting parts are formed at both ends of the upper cantilever 5, ensuring that both ends of the upper cantilever 5 can be fixedly connected to the corresponding ends of the lower cantilever 2 and that the distance between the upper cantilever 5 and the lower cantilever 2 is constant, reserving space for the installation of the upper foot 4 and the lower foot 6, ensuring that the suspension 3 is effectively clamped and positioned, and protecting the shock absorber foot. 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, ensuring that the connecting part is vertically exposed, facilitating the disassembly and assembly of the connecting part and the lower cantilever 2.

[0038] 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.

[0039] Example 2:

[0040] Compared to Embodiment 1, this embodiment provides a mattress.

[0041] like Figure 6 The mattress shown includes a mattress body, airbags 18 within the mattress body, and a control box. The control box is connected to the airbags 18 to allow for adjustable air pressure within the airbags 18. The control box adjusts the air pressure within each airbag 18 and uses limiting components to prevent the suspension 3 from pulling on the shock-absorbing feet due to excessive deviation from the cantilever.

[0042] 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.
