Description

Technical Field

[0001] The utility model belongs to the field of intelligent bed controllers, and particularly relates to a controller and an intelligent bed with good shock absorption effect. 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 an air pump and a solenoid valve connected to the air pump. When the air pump is working, it will generate relatively large vibrations, and all components inside the controller are in surface contact. The vibrations generated are likely to cause resonance among the components in surface contact, and correspondingly, it will generate noise that is not conducive to sleep. Therefore, when the controller is working, users with light sleep will be disturbed by the vibrations generated by the air pump and thus cannot fall asleep. Therefore, it is necessary to improve the existing control to reduce the impact of vibrations on users and enhance the user experience. Summary of the Utility Model

[0003] Aiming at the problem that the existing controller generates large vibrations and affects the sleep of users, the utility model provides a controller and an intelligent bed with good shock absorption effect. By suspending the solenoid valve assembly and setting a buffer at the connection between the suspension and the inner shell, the vibration conduction generated by the air pump assembly is reduced, and the impact of vibrations on users is effectively reduced.

[0004] The utility model adopts the following technical solutions: A controller with good shock absorption effect, comprising:

[0005] An air pump assembly for driving gas to generate an air flow;

[0006] An inner shell for accommodating the air pump assembly;

[0007] A solenoid valve assembly, which is connected to the air pump assembly and is located in the space surrounded by the inner shell. By opening and closing the solenoid valve assembly, the air flow generated by the air pump assembly is led out;

[0008] A suspension, which is connected to the upper part of the inner shell. The air pump assembly is suspended from the bottom up and connected to the suspension, and a gap is formed between the air pump assembly and the inner shell;

[0009] A buffer is provided at the connection between the suspension and the inner shell.

[0010] The air pump assembly is the main component generating vibrations. The air pump assembly is suspended from the bottom up and connected to the suspension, and a buffer is provided at the connection between the suspension and the inner shell. Therefore, the air pump assembly does not directly contact the inner shell. Then, the vibration transmission path of the vibrations generated by the air pump assembly to the inner shell through the buffer and the suspension is long, and the vibrations are gradually weakened, generating little noise, effectively reducing the impact of vibrations.

[0011] Furthermore, the buffer member includes a cantilever, which is a rigid elastic member. Both ends of the cantilever are connected to the upper part of the inner housing, and the middle section of the cantilever is connected to the suspension from bottom to top. The cantilever being a rigid elastic member can ensure the support strength and reduce the vibration conduction. Since both ends of the cantilever are connected to the upper part of the inner housing and the middle section is connected to the suspension, the vibration generated by the air pump assembly connected to the suspension is transmitted upward to the cantilever and then to the upper part of the inner housing. The connections between various components are point contacts. When vibration is transmitted, resonance is not easily generated, and the vibration transmission path is relatively long, so the vibration is easily weakened.

[0012] Furthermore, the buffer member further includes shock-absorbing feet, which are soft elastic members. External threads are provided on the upper part of the shock-absorbing feet. Nuts are embedded in the suspension, and the upper part of the shock-absorbing feet is threadedly connected to the nuts. The lower part of the shock-absorbing feet is fixed to the cantilever through threaded connectors. The cantilever and the shock-absorbing feet are used in combination. The shock-absorbing feet being soft elastic members can absorb part of the vibration and reduce the vibration transmitted to the inner housing.

[0013] Furthermore, a first shock-absorbing rubber is provided at the connection between the air pump assembly and the suspension. The first shock-absorbing rubber includes a damping portion and a connecting portion. The damping portion can penetrate through the suspension, and the connecting portion is connected to the outside of the air pump assembly. Since the first shock-absorbing rubber is made of a soft material, it can absorb part of the vibration, and the vibration generated by the air pump assembly is weakened by the first shock-absorbing rubber before reaching the suspension, effectively reducing the amount and amplitude of the vibration transmitted to the suspension.

[0014] Furthermore, the air pump assembly includes an air pump main body and a box body for accommodating the air pump main body. At least two screw rods are horizontally arranged in the box body, and the air pump main body is connected to the screw rods through shock-absorbing belts so that the air pump main body is suspended in the box body. The air pump main body is suspended in the box body, and the vibration generated by it is only transmitted to the box body through the horizontally arranged screw rods and the shock-absorbing belts. The shock-absorbing belts can absorb part of the vibration, effectively reducing the amount and amplitude of the vibration transmitted to the box body.

[0015] Furthermore, the controller with good shock-absorbing effect further includes a housing, which is located outside the inner housing and is connected to the inner housing through connecting columns so that a gap is formed between the housing and the inner housing. The connecting columns are shock-absorbing members. The housing surrounds the inner housing, playing a good protective role. And there are connecting columns between the inner housing and the housing, making the inner housing and the housing in point contact, and the connecting columns being shock-absorbing members, which can reduce the vibration conduction by absorbing part of the vibration.

[0016] Further, the solenoid valve assembly is connected to the lower part of the suspension from bottom to top through a second shock-absorbing rubber. This structure suspends the solenoid valve assembly on the suspension. Since the solenoid valve assembly also generates vibrations during operation, the provided second shock-absorbing rubber can absorb part of the vibrations and effectively reduce vibration transmission.

[0017] Further, a main air box is provided between the solenoid valve assembly and the air pump assembly to buffer the air flow passing through the main air box, and the main air box is connected to the suspension. The air flow generated by the air pump assembly first flows into the main air box and then enters the solenoid valve assembly. In this way, the air flow is initially buffered at the main air box, and the vibrations generated by the air flow can be weakened.

[0018] Further, a female connector seat is provided on the inner housing, and the solenoid valve assembly is connected to the female connector seat through a secondary buffer air box. The secondary buffer air box is used to buffer the air flow passing through it; a secondary circuit board and a main circuit board are respectively provided on the upper and lower sides of the secondary buffer air box, and the secondary circuit board is connected to the main circuit board through a cable. The secondary buffer air box is located between the solenoid valve assembly and the female connector seat to buffer the air flow flowing out of the solenoid valve assembly. In this way, the air flow is further buffered at the secondary buffer air box, and the vibrations generated by the air flow are further weakened.

[0019] As another inventive point, the present application also provides an intelligent bed, which includes 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 good shock absorption effect.

[0020] The beneficial effects of the present utility model are as follows: The present application provides a controller and an intelligent bed with good shock absorption effect. The air pump assembly is suspended from bottom to top on the suspension. A buffer is provided at the connection between the suspension and the inner housing. The transmission path of the vibrations generated by the air pump assembly to the inner housing through the buffer and the suspension is long, and the vibrations are gradually weakened, resulting in less noise and good shock absorption effect, effectively reducing the influence brought by the vibrations.

However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] The controller with good shock absorption effect in this embodiment, as Figures 1 to 6 shown, includes:

[0032] An air pump assembly 1 for driving gas and thus generating an air flow;

[0033] An inner housing 2 for accommodating the air pump assembly 1;

[0034] A solenoid valve assembly 8, the solenoid valve assembly 8 is connected to the air pump assembly 1 and is located in the space surrounded by the inner housing 2. By opening and closing the solenoid valve assembly 8, the air flow generated by the air pump assembly 1 is led out;

[0035] A suspension 3, the suspension 3 is connected to the upper part of the inner housing 2, and the air pump assembly 1 is suspended from bottom to top on the suspension 3 and forms a gap with the inner housing 2;

[0036] A buffer member is provided at the connection between the suspension 3 and the inner housing 2.

[0037] In this embodiment, the buffer member includes a cantilever 4, which is a rigid elastic member. Both ends of the cantilever 4 are connected to the upper part of the inner housing 2, and the middle section of the cantilever 4 is connected to the suspension 3 from bottom to top. The cantilever 4 is a rigid elastic member, which can ensure the support strength and reduce the vibration conduction. Since both ends of the cantilever 4 are connected to the upper part of the inner housing 2 and the middle section is connected to the suspension 3, the vibration generated by the air pump assembly 1 connected to the suspension 3 is transmitted upward to the cantilever 4 and then to the upper part of the inner housing 2. The connections of all components are point contacts. When vibration is transmitted, resonance is not easily generated, and the vibration transmission path is relatively long, so the vibration is easily weakened.

[0038] The buffer member further includes shock-absorbing feet 5, which are soft elastic members. The upper part of the shock-absorbing feet 5 is provided with external threads, and nuts are embedded in the suspension 3. The upper part of the shock-absorbing feet 5 is connected to the nuts by threads, and the lower part of the shock-absorbing feet 5 is fixed to the cantilever 4 by threaded connectors. The cantilever and the shock-absorbing feet are used in combination. The shock-absorbing feet 5 are soft elastic members, which can absorb part of the vibration and reduce the vibration transmitted to the inner housing 2.

[0039] A first shock-absorbing rubber 1-5 is provided at the connection between the air pump assembly 1 and the suspension 3. The first shock-absorbing rubber 1-5 includes a damping part and a connecting part. The damping part can pass through the suspension 3, and the connecting part is connected to the outside of the air pump assembly 1. Since the first shock-absorbing rubber 1-5 is made of soft material, it can absorb part of the vibration. The vibration generated by the air pump assembly 1 is weakened by the first shock-absorbing rubber 1-5 before reaching the suspension 3, effectively reducing the vibration amount and vibration amplitude transmitted to the suspension. The first shock-absorbing rubber is connected to the outside of the air pump assembly by clamping, bonding or sleeving. The damping part is clamped on the suspension 3 to play a good positioning role, and the connecting part is arranged on the outside of the air pump assembly 1, specifically, it can be bonded or clamped on the outside of the air pump assembly 1 to play a good connecting role and prevent the air pump assembly from shifting.

[0040] The air pump assembly 1 includes an air pump main body 1-1 and a box body 1-2 for accommodating the air pump main body 1-1. Four screws 1-4 are horizontally arranged in the box body 1-2, and the air pump main body 1-1 is connected to the screws 1-4 through a shock-absorbing belt 1-3 so that the air pump main body 1-1 is suspended in the box body 1-2. The air pump main body 1-1 is suspended in the box body 1-2, and the vibration generated by it is transmitted to the box body 1-2 only through the horizontally arranged screws 1-4 and the shock-absorbing belt 1-3. The shock-absorbing belt 1-3 can absorb part of the vibration, effectively reducing the vibration amount and vibration amplitude transmitted to the box body 1-2.

[0041] The controller with good shock absorption effect further includes a housing 6, which is located outside the inner housing 2 and is connected to the inner housing 2 through connecting columns 6-1, so that a gap is formed between the housing 6 and the inner housing 2, and the connecting columns 6-1 are shock-absorbing members. The housing 6 encloses the inner housing 2 therein, playing a good protective role. And there are connecting columns 6-1 between the inner housing 2 and the housing 6, making the inner housing 2 and the housing 6 in point contact, and the connecting columns 6-1 being shock-absorbing members, which can reduce vibration conduction by absorbing part of the vibration.

[0042] The solenoid valve assembly 8 is connected to the lower part of the suspension 3 from bottom to top through a second shock-absorbing rubber 8-1. This structure makes the solenoid valve assembly suspended on the suspension. The solenoid valve assembly will also generate vibration during operation, and the provided second shock-absorbing rubber can absorb part of the vibration and effectively reduce vibration transmission.

[0043] An upper cover 7 is provided above the suspension 3, and the upper cover 7 is connected to the inner housing 2 through threaded connectors. The upper cover 7 covers the top of the inner housing 2 to protect the suspension 3 therein to prevent accidental contact due to the external placement of the suspension 3.

[0044] A main air box 9 is provided between the solenoid valve assembly 8 and the air pump assembly 1 to buffer the air flow passing through the main air box 9, and the main air box 9 is connected to the suspension 3. The air flow generated by the air pump assembly 1 first flows into the main air box 9 and then enters the solenoid valve assembly 8. In this way, the air flow is initially buffered at the main air box, and the vibration generated by the air flow can be weakened.

[0045] A female connector base 2-1 is provided on the inner housing 2, and the solenoid valve assembly 8 is connected to the female connector base 2-1 through a secondary buffer air box 10, and the secondary buffer air box 10 is used to buffer the air flow passing through the secondary buffer air box 10; a secondary circuit board 11 and a main circuit board 12 are respectively provided on the upper and lower sides of the secondary buffer air box 10, and the secondary circuit board 11 and the main circuit board 12 are connected by a wiring harness. The secondary buffer air box 10 is located between the solenoid valve assembly 8 and the female connector base 2-1 to buffer the air flow flowing out of the solenoid valve assembly 8. In this way, the air flow is further buffered at the secondary buffer air box 10, and the vibration generated by the air flow is further weakened.

[0046] The air pump assembly 1 is the main component generating vibration. The air pump assembly 1 is suspended from bottom to top on the suspension 3. A buffer member is provided at the connection between the suspension 3 and the inner housing 2. Therefore, the air pump assembly 1 does not directly contact the inner housing 2. Then the vibration generated by the air pump assembly 1 has a long transmission path through the buffer member and the suspension 3 to the inner housing 2, and the vibration is gradually weakened, generating little noise and effectively reducing the influence brought by the vibration.

[0047] In this embodiment, the vibration generated by the air pump assembly 1 reaches the first-level buffering effect through the cantilever 4. The shock-absorbing feet 5 are provided to absorb part of the vibration, achieving the second-level buffering effect. The air pump assembly 1 is suspended on the suspension 3 through the first shock-absorbing rubber 1-5, achieving the third-level shock-absorbing effect. The air pump main body 1-1 is connected to the screw through the shock-absorbing belt 1-3, achieving the fourth-level shock-absorbing effect. In this way, the influence of vibration on the user is weakened step by step, and the shock-absorbing effect is better.
