Description

Technical Field

[0001] The utility model relates to a massage device, in particular to a massage seat cushion for a wheelchair. Background Art

[0002] The massage seat cushion is a common massage device at present. However, sometimes it has a large volume due to mechanical transmission. The seat surface of a wheelchair is often small and the wheelchair often has a foldable design. If the massage seat cushion is to be used on a wheelchair, it needs to be optimized in terms of miniaturization and detachable design to cope with the narrow seat surface of the wheelchair and the storage when the wheelchair is in a folded state. Summary of the Invention

[0003] The utility model provides a massage seat cushion for a wheelchair, which realizes the miniaturization design of the massage seat cushion in an inflatable manner and can be conveniently disassembled and assembled on the wheelchair.

[0004] The utility model adopts the following technical solutions.

[0005] A massage seat cushion for a wheelchair, wherein the massage surface of the massage seat cushion is arranged at the upper cover of the seat cushion, and the upper cover is supported on the top surfaces of a plurality of air bags symmetrically arranged at the lower part of the seat cushion; each air bag is provided with an independent air pump. When massage is needed, each air pump inflates or deflates in a preset order to make the top surface of the air bag connected thereto rise and fall, so that the massage surface is in a left-right swing state or a lifting and pushing state.

[0006] The lower part of the upper cover is provided with a grid structure.

[0007] A vibration motor is arranged in the massage seat cushion, and the vibration motor is connected with the grid structure to drive the massage surface to vibrate through the grid structure.

[0008] A circuit board with a heating coil is arranged in the massage seat cushion, and the circuit board is connected with the grid structure of the upper cover to heat the massage surface.

[0009] The number of the air bags is two, which are symmetrically arranged on the left and right sides of the central axis of the bottom surface of the upper cover.

[0010] The circuit board is arranged below the central part of the bottom surface of the upper cover and placed on the air bag.

[0011] The air pump and the vibration motor are both powered by a battery in the massage seat cushion. The massage seat cushion is detachably placed on the seat surface of the wheelchair. The upper cover is a rectangular inverted basin-shaped body, and its pelvic cavity is buckled on the air bag.

[0012] The air pump and the vibration motor are both connected with a controller beside the massage seat cushion through cables.

[0013] A plurality of control buttons and indicator lights are arranged at the controller.

[0014] The circuit board is internally provided with a memory, and the memory stores preset data on the charging and discharging sequence of each air pump. When the air pump charges and discharges air according to the preset data sequence, the driving massage surface performs a rocking and pushing / pulling action corresponding to the preset data.

[0015] In the present utility model, since the rocking and pushing / pulling action of the massage surface of the massage seat cushion is driven by air bags and there is no large mechanical transmission device, the miniaturization of the product can be achieved, and it can be conveniently placed on the seat surface of a wheelchair.

[0016] In the present utility model, since the massage seat cushion is completely driven by an internal battery to work, there is no need for external wiring cables. It can be directly placed on the seat surface of the wheelchair. When the wheelchair is folded and stored, the massage seat cushion can be directly removed without affecting the folding operation of the wheelchair.

[0017] In the present utility model, heat conduction and vibration conduction to the massage surface are achieved through a grille structure. On the one hand, the heat absorption of the grille structure is small, which can enable the heat of the heating coil to quickly reach the massage surface through the grille structure. On the other hand, the grille structure is lighter in weight, which can make the massage seat cushion lighter in weight and also make the vibration of the vibration motor easier to be transmitted to the massage surface.

[0024] As shown in the figure, a massage seat cushion for a wheelchair, the massage surface of the massage seat cushion is arranged at the upper cover 1 of the seat cushion, and the upper cover is supported on the top surfaces of a plurality of air bags symmetrically arranged at the lower part of the seat cushion; each air bag is provided with an independent air pump 8. When massage is required, each air pump inflates or deflates in a preset sequence to cause the top surface of the air bag connected thereto to rise and fall, so that the massage surface is in a left - right rocking state or a lifting and pushing / pulling state.

[0025] The lower part of the upper cover is provided with a grille structure 2.

[0026] A vibration motor 4 is provided inside the massage seat cushion. The vibration motor is connected to the grille structure to drive the massage surface to vibrate through the grille structure.

[0027] A circuit board 7 with a heating coil 6 is provided inside the massage seat cushion. The circuit board is connected to the grille structure of the upper cover to heat the massage surface.

[0028] The number of airbags is two, which are symmetrically arranged on the left and right sides of the central axis of the bottom surface of the upper cover.

[0029] The circuit board is arranged below the central part of the bottom surface of the upper cover and placed on the airbag.

[0030] The air pump and the vibration motor are both powered by a battery 10 inside the massage seat cushion. The massage seat cushion is placed on the seat surface of the wheelchair in a separable manner. The upper cover is a rectangular inverted basin-shaped body, and its pelvic cavity is buckled on the airbag.

[0031] The air pump and the vibration motor are both connected to a controller 3 beside the massage seat cushion via cables.

[0032] A plurality of control buttons and indicator lights are provided at the controller.

[0033] A memory is provided inside the circuit board. Preset data of the inflation and deflation sequence of each air pump is stored in the memory. When the air pump inflates and deflates according to the preset data sequence, it drives the massage surface to perform a swaying push-pull action corresponding to the preset data.

[0034] In this example, the airbag is placed in a retractable and liftable storage box, together with the vibration motor and the circuit board, to form a lifting base. When the upper shell is buckled on the lifting base and the airbag drives the lifting base to retract, lift or swing left and right, it drives the upper shell to lift or swing.

[0035] In this example, an MCU processor is provided on the circuit board. According to the key instructions of the controller and the preset data in the memory, it controls the airbag, the vibration circuit, and the heating coil to work in the working modes in the preset data.

[0036] Embodiment:

[0037] In this example, an on / off key is provided at the controller. Press it briefly to turn on. The buzzer beeps once, and the power indicator light stays on. All function buttons can only complete function operations after the on / off key is turned on;

[0038] Press the on / off key once briefly: Turn on. The buzzer beeps once, the exhaust valve connected to the air pump opens, and the main board dynamic running lights cycle;

[0039] Press the on / off key twice briefly: The buzzer beeps long once, turn off, and the indicator light goes out;
