Description

Technical Field

[0001] The utility model belongs to the field of intelligent bed accessories, and particularly relates to a controller with a symmetrical structure and an intelligent bed. Background Art

[0002] Existing intelligent beds use a controller to inflate and deflate to achieve the function of an air mattress. The existing controller usually includes a solenoid valve connected to an air pump. When the air flow directly flows from the air pump assembly to the solenoid valve, a large vibration will be generated. Each component inside the controller is placed layer by layer, and the contact area is large. Especially when each component is asymmetrically arranged, the center of gravity of the controller will be offset to one side, and large vibrations will be generated at the contact surfaces of each component, and the amplitudes are different. Such vibrations with different amplitudes will generate noise that is not conducive to sleep. When this existing controller is working, users with light sleep will be disturbed by the vibration generated by the air pump and thus cannot fall asleep. Therefore, it is necessary to improve the existing controller to reduce the impact of vibration on users and enhance the user experience. Summary of the Utility Model

[0003] Aiming at the problem that the internal structure of the controller for the existing intelligent mattress is asymmetric, resulting in vibrations that are not conducive to sleep, the utility model provides a controller with a symmetrical structure and an intelligent bed. By providing a main air box for buffering gas between the air pump assembly and the solenoid valve assembly to reduce the noise generated by the air flow, and by arranging a suspension with a symmetrical structure inside the controller and configuring a symmetrical structural layout to ensure the symmetry of the internal structure of the controller, the generation of vibrations with different amplitudes is reduced, and thus the impact of vibrations is alleviated.

[0004] The technical solution adopted by the utility model is as follows: A controller with a symmetrical structure includes:

[0005] An inner housing having a receiving cavity;

[0006] A suspension disposed on the upper part of the inner housing for support; the suspension has a symmetrical structure and has a symmetry axis;

[0007] An air pump assembly accommodated in the receiving cavity for generating air flow; at least two air pump assemblies are provided and are arranged on both sides of the suspension along the symmetry axis;

[0008] At least two main air boxes are provided and are arranged along the symmetry axis; each main air box is connected to an air pump assembly so that the air flow generated by each air pump assembly can be guided to the corresponding main air box;

[0009] A solenoid valve assembly is disposed on the suspension. The input end of the solenoid valve assembly is connected to the main air box. By opening and closing the solenoid valve assembly, the on-off and flow direction of the air flow are controlled. The solenoid valve assembly is clamped between two adjacent main air boxes or two adjacent air pump assemblies;

[0010] A plurality of shock-absorbing feet are provided at the connection between the suspension and the inner housing, and are evenly distributed above the air pump assembly.

[0011] A suspension with a symmetric structure is adopted. A main air box for buffering gas is provided between the air pump assembly and the solenoid valve assembly. The main air box, the air pump assembly are symmetrically arranged on the suspension, and the solenoid valve assembly is arranged between two adjacent main air boxes or two adjacent air pump assemblies. Each component is symmetrically arranged on the suspension to ensure the stability of the center of gravity and reduce the generation of vibrations with different amplitudes. The vibrations generated by each component are evenly transmitted to the suspension and then evenly transmitted from the suspension to the inner housing. Moreover, shock-absorbing feet are provided at the connection between the suspension and the inner housing, which can absorb part of the vibrations and thus alleviate the influence brought by the vibrations.

[0012] Furthermore, the suspension has a concave cavity. The air pump assembly is arranged on both sides outside the concave cavity. A secondary buffer air box is arranged in the concave cavity. The input end of the secondary buffer air box is connected to the output end of the solenoid valve assembly, and the output end of the secondary buffer air box is connected to a female connector seat arranged on the inner housing. The concave cavity is provided to separate the secondary buffer air box and the main air box. The gas is output outward through the female connector seat. After being buffered by the main air box and the secondary buffer air box, the noise generated when the air flow moves is effectively reduced.

[0013] Furthermore, the shock-absorbing foot is connected to a cantilever. Both ends of the cantilever are connected to the upper part of the inner housing. The cantilever is a spring steel sheet and is connected to the lower part of the shock-absorbing foot. The cantilever provides sufficient rigid support and can reduce the contact area between the suspension and the inner housing, thereby reducing the vibration transmission path, and absorbing part of the vibrations through the shock-absorbing foot, so as to effectively alleviate the influence brought by the vibrations.

[0014] Furthermore, the suspension has at least two upward convex parts, which are symmetrically arranged on both sides of the concave cavity. The cantilever is connected to the lower part of the convex part through the shock-absorbing foot. By setting the uneven structure, the strength of the suspension itself is enhanced, and the convex parts are symmetrically arranged on both sides of the concave cavity, meeting the requirement of the symmetric structure to reduce vibrations.

[0015] Furthermore, the shock-absorbing foot is a rubber part, which includes an upper part with an external thread and a lower part with an internal thread. The shock-absorbing foot is screwed upward on both sides of the concave cavity through the external thread and is connected to the cantilever downward through a connecting piece that mates with the internal thread. The shock-absorbing foot is a rubber part, which has good vibration absorption performance and good elasticity, and can fill the gaps. The shock-absorbing foot is screwed upward on both sides of the concave cavity through the external thread, and can also meet the requirement of the symmetric structure to reduce vibrations.

[0016] Further, shock-absorbing belts with damping parts are provided on the outer sides of both the air pump assembly and the solenoid valve assembly. The damping part is located at one end of the shock-absorbing belt. The suspension is provided with a limit hole, and the damping part can be embedded in the limit hole. The arrangement of the damping part passing through the limit hole enables the air pump assembly and the solenoid valve assembly to be suspended on the suspension, and only the vibration is transmitted through the damping part. In this way, the contact area between the air pump assembly, the solenoid valve assembly and the suspension is small, and the shock-absorbing belt itself can absorb part of the vibration, further reducing the vibration transmission.

[0017] Further, the inner housing is a hollow structure, and its upper part is connected with an upper cover for covering the suspension. The upper cover covers the top of the inner housing to prevent the components in the inner housing from being exposed, effectively reducing the probability of accidental contact.

[0018] Further, an outer housing is further provided on the outer side of the inner housing. Support columns are provided on the inner side of the bottom of the outer housing, and the inner housing is connected to the support columns. The support columns are shock-absorbing members. The outer housing plays a protective role, and the outer housing and the inner housing are connected by the support columns. The vibration on the inner housing is only transmitted to the outer housing through the support columns, and the support columns are shock-absorbing members, which can absorb part of the vibration, effectively reducing the vibration transmission, and then alleviating the noise impact caused by the vibration.

[0019] Further, a secondary circuit board and a main circuit board connected by a wiring harness are respectively provided on the upper and lower sides of the secondary buffer air box. The main circuit board is connected to the outer side of the bottom of the concave cavity, and the secondary circuit board is located above the female connector base. There are two circuit boards, which are respectively located on the upper and lower sides of the secondary buffer air box and are connected by a wiring harness, avoiding the problem of messy wiring.

[0020] As another inventive point, the present application also provides an intelligent bed, including a bed frame, an air mattress, and a controller for controlling the operation of the air mattress. The controller is installed below the bed frame and is connected to the air mattress through an air pipeline. The controller is the above-mentioned controller with a symmetrical structure.

[0021] The beneficial effects of the present utility model are as follows: The present application is a controller with a symmetrical structure and an intelligent bed. A suspension with a symmetrical structure is adopted, and each component is symmetrically arranged on the suspension to ensure the stability of the center of gravity and reduce the generation of vibrations with different amplitudes. The vibrations generated by each component are evenly transmitted to the suspension and then evenly transmitted to the inner housing from the suspension. Moreover, shock-absorbing feet are provided at the connection between the suspension and the inner housing, which can absorb part of the vibration and effectively alleviate the impact caused by the vibration.

The solenoid valve assembly 5 is clamped between two adjacent main air boxes 4.

[0038] A plurality of shock-absorbing feet 6 are provided at the connection between the suspension 2 and the inner housing 1, and are evenly distributed above the air pump assembly 3.

[0039] The suspension 2 with a symmetric structure is adopted. A main air box 4 for buffering gas is provided between the air pump assembly 3 and the solenoid valve assembly 5. The main air box 4, the air pump assembly 3 are symmetrically arranged on the suspension 2, and the solenoid valve assembly 5 is arranged between two adjacent main air boxes 4.

Moreover, shock-absorbing feet 6 are provided at the connection between the suspension 2 and the inner housing 1, which can absorb part of the vibrations, thereby alleviating the influence brought by the vibrations.

[0040] The suspension 2 has a concave cavity 2-1 with a downward concave shape. The air pump assembly 3 is arranged on both sides outside the concave cavity 2-1.

[0041] The shock-absorbing foot 6 is connected to a cantilever 10. Both ends of the cantilever 10 are connected to the upper part of the inner housing 1.

The damping parts 11-1 are located at one end of the shock-absorbing belts 11. The suspension 2 is provided with limit holes, and the damping parts 11-1 can be embedded in the limit holes. The arrangement of the damping parts passing through the limit holes enables the air pump assembly 3 and the solenoid valve assembly 5 to be suspended on the suspension 2, and only the vibration is transmitted through the damping parts 11-1. In this way, the contact area between the air pump assembly 3, the solenoid valve assembly 5 and the suspension 2 is small, and the shock-absorbing belt 11 itself can absorb part of the vibration, further reducing the vibration transmission.

[0045] The inner housing 1 is a hollow structure, and its upper part is connected to the upper cover 12 for covering the suspension 2. The upper cover 12 covers the top of the inner housing 1 to prevent the components in the inner housing 1 from being exposed, effectively reducing the probability of accidental contact.

[0046] The outside of the inner housing 1 is further provided with an outer housing 13. The inner side of the bottom of the outer housing 13 is provided with support columns 13-1, and the inner housing 1 is connected to the support columns 13-1. The support columns 13-1 are shock-absorbing parts. The outer housing 13 plays a protective role, and the outer housing 13 and the inner housing 1 are connected by the support columns 13-1. The vibration on the inner housing 1 is only transmitted to the outer housing 13 through the support columns 13-1, and the support columns 13-1 are shock-absorbing parts, which can absorb part of the vibration, effectively reducing the vibration transmission, and further alleviating the noise impact caused by the vibration.
