Description

Technical Field

[0001] This utility model relates to the technical field of massagers, and in particular to a massage cushion. Background Technology

[0002] Long-distance driving or travel requires both drivers and passengers to sit in car seats for extended periods, easily leading to fatigue. Furthermore, prolonged periods of poor posture, such as slouching or arching the back, can cause back muscle tension and pain, manifesting as soreness, stiffness, weakness, or persistent pain in the lower back. To alleviate these problems, many people carry lumbar supports to place on their seat backs for lumbar support. However, this method only provides limited relief and cannot address overall back discomfort. In addition, office workers who sit for long periods in swivel chairs or other office chairs also face lower back discomfort, and ordinary lumbar supports are not very effective. More importantly, lumbar supports placed directly on the seat when not in use are prone to falling off and getting dirty. In a car, they may also slip off due to inertia during braking, causing further damage.

[0003] To further improve lower back problems, some users choose to use back massagers. These devices typically relieve fatigue and achieve fitness effects through massage, generally consisting of a backrest and a seat cushion connected together, with adjustable straps on both for securing them to a car seat. However, existing back massagers have significant drawbacks: First, the direct connection between the backrest and seat cushion results in a complex structure, large and bulky overall size, making them inconvenient to carry; second, their applicability is limited, only able to be fixed to a single car seat, and cannot be adapted to rows of seats (such as the rear seats of a private car or multi-seat sofas at home); third, they lack stability during use, even when secured to the seat with straps, they can easily slip off due to the user's movements, causing inconvenience and affecting the actual usage effect.

[0004] In view of this, this utility model addresses the numerous defects and inconveniences caused by the imperfections in the structural design of existing backrest massagers. Through in-depth conception and active research and improvement, this utility model was finally developed. Utility Model Content

The air bag 6 is connected to the air valve assembly 5 through an air pipe. The air valve assembly 5 is connected to the air pump assembly 4 and the center plate 7. The motor 3 is connected to the center plate 7. The motor 3, air pump assembly 4, air valve assembly 5 and center plate 7 are respectively located inside the main body 1. The control assembly 8 is connected to the center plate 7. The connecting assembly 9 is located on the back of the main body 1 or the outer cover 2 for connection with the seat.

[0025] To further enhance the massage effect, the massage cushion also includes a heating element 16. The heating element 16 is installed on the front of the main body 1 or the back of the outer cover 2 and is connected to the center plate 7. By setting the heating element 16, the massage cushion of this utility model has a heating massage effect. In this embodiment, the heating element 16 is a heating film sheet, which is set on the main body 1 or outer cover 2 below the air bag 6, corresponding to the waist position, so as to provide a heat compress effect to the waist, relieve waist pain, and improve the massage effect.

[0026] The massage cushion of this utility model also includes a charging component 10, which includes a charging plate 101, a charging base 102, a charging base 103, and a charging head 104. The charging base 102 is disposed on the charging base 103. The charging head 104 is connected to the power input interface of the charging base 102 through a power cord to convert the mains power into low-voltage DC power to power the charging base 102. The charging base 102 has a built-in charging module (including rectification and voltage regulation circuits), which contacts the charging plate 101 (integrated receiving electrode / coil and protection circuit) through metal electrodes / pins / wireless coils to realize power transmission. The output end of the charging plate 101 is directly connected to the battery management interface of the center plate 7 through a wire.

[0027] In this embodiment, the central plate 7 is also provided with a preset fixed frequency electrical signal, and the control component 8 is provided with a vibration mode corresponding to the corresponding fixed frequency electrical signal. The motor 3 is a linear vibration motor. By selecting the preset vibration mode through the control component 8, the central plate 7 generates an electrical signal of the corresponding frequency according to the selected vibration mode (such as relaxation mode corresponding to 30Hz, deep relaxation mode corresponding to 60Hz, etc.), driving the linear vibration motor to vibrate. The muscle relaxation effect is achieved through regular vibration at a fixed frequency.

[0028] In this embodiment, the air pump assembly 4, the air valve assembly 5, and the center plate 7 are installed in a device box 11. The body 1 is a molded sponge. The lower back of the body 1 is provided with a device groove 12 for the device box 11 to be installed. The lower front of the body 1 is provided with a motor groove 13 for the motor 3 to be installed. Above the motor groove 13 on the front of the body 1, there is an air bag groove 14 corresponding to the air bag 6. The air bag 6 is installed on the air bag groove 14. The side of the body 1 is provided with a control groove 15 for the control assembly 8 to be installed. The outer sleeve 2 is provided with a through hole corresponding to the control groove 15.

[0029] The air pump assembly 4 includes an air pump 41 and an air pump silicone sleeve 42. The air pump 41 is enclosed in the air pump silicone sleeve 42. There are multiple air bags 6. The air valve assembly 5 has solenoid valves corresponding to the number of air bags 6. The air pump 41 is connected to the air valve assembly through a main air pipe. The air valve assembly 5 is connected to multiple air bags 6 through branch air pipes. By supplying air with the air pump 41 and switching the air path with the solenoid valves of the air valve assembly 5, the inflation and deflation cycle of the air bags 6 is realized, simulating massage movements. During the inflation phase, the air pump 41 is activated, and the solenoid valve corresponding to the target air bag in the air valve assembly 5 is energized, opening the "air pump → air bag" passage and closing the exhaust passage. Compressed air enters the air bag 6 through the air distribution pipe, and the air bag 6 expands to lift the muscles at the contact point, producing a squeezing and supporting effect (such as the lumbar air bag inflating to support the lumbar spine and relieve pressure). During the pressure holding / massage phase, after the air bag is inflated to the preset pressure, the solenoid valve remains in the passage state, and the air bag remains in an inflated state (pressure holding), forming continuous pressure on the muscles. "Pulse inflation" can be achieved by quickly switching the solenoid valve on and off, simulating tapping and kneading actions (such as the air bag repeatedly inflating and deflating in small amplitudes to produce a vibration sensation). During the deflation phase, the solenoid valve is de-energized to switch the passage, close the connection of the air pump 41, and open the exhaust passage between the air bag 6 and the atmosphere (the air bag can also be deflated by reverse air extraction through the air pump 41). The air bag 6 deflates and contracts, releasing muscle pressure and completing one massage cycle.

[0030] The control component 8 includes a button upper cover 81 and a button lower cover 82 that are snapped together, a button plate 83 disposed between the button upper cover 81 and the button lower cover 82, and a button 84 disposed on the button plate 83 and facing the button upper cover 81. The button upper cover 81 is provided with a button hole 811 corresponding to the button 84, and the button lower cover 82 is installed in the control groove 15 of the main body 1.

[0031] In this embodiment, the connecting component 9 includes a connecting piece 91 and a snap-fit ​​part 92. One end of the connecting piece 91 is disposed on the outer sleeve 2, and the other end of the connecting piece 91 is fixed together with the snap-fit ​​part 92. The snap-fit ​​part 92 is detachably disposed between the backrest and the seat cushion of the seat.

[0032] Specifically, the outer cover 2 is a leather case with an opening on the back. The connecting piece 91 is sewn to the opening of the leather case, or it can be detachably connected to the leather case via a zipper. In this embodiment, the connecting piece 91 is an elastic cord. The snap-fit ​​part 92 includes a connecting outer cover 921 and an inlay disposed within the connecting outer cover 921. The inlay is preferably made of sponge, but other materials, such as soft or hard materials, can also be used, so that the thickness of the snap-fit ​​part 92 is greater than the thickness of the connecting piece 91. The connecting piece 91 is designed as an elastic cord for easy installation. During installation, the massage cushion of this utility model is placed directly on the seat, and the snap-fit ​​part 92 of the connecting assembly is inserted into the gap between the backrest and the seat cushion, so that the backrest and the seat cushion clamp the snap-fit ​​part 92, preventing the massage cushion from detaching from the seat. During disassembly, simply remove the snap-fit ​​part 92 from the gap between the backrest and the seat cushion.

[0033] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
