Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, and in particular to a rotary foot massage device and an automobile seat. Background Art

[0002] At present, the massage function of car seats is mainly focused on the waist, back, buttocks and legs, with relatively little attention paid to the feet. In order to improve the comfort and differentiated competitiveness of seats, some manufacturers have begun to design massage devices for the feet.

[0003] However, most of the current foot massage devices use air bag massage, but there are many acupuncture points on the human foot and the foot is light in weight, so the air bag massage device has the disadvantage of low massage force and cannot effectively stimulate the acupuncture points on the sole of the foot. If a professional mechanical foot massage device is used, it has the problem of complex structure and large size, and is not suitable for installation in the narrow space of a car. Summary of the invention

[0004] In view of this, one of the purposes of the present invention is to provide a rotary foot massage device which adopts a light and thin design and can effectively massage the foot.

[0005] To achieve the above purpose, the technical solution of the present invention is as follows:

[0006] A rotary foot massage device, the key of which is that it comprises: a base, massage components are rotatably mounted on the upper sides of both left and right ends of the base, massage convex blocks are arranged on the top of the massage components, and the massage convex blocks are offset to one side relative to the rotation center line of the massage components;

[0007] The base is provided with a driving mechanism for driving the massage component to rotate in a horizontal plane where the sole of the foot is located.

[0008] With the above structure, the driving mechanism drives the massage component to perform horizontal rotational motion, and the massage protrusions rotate with the massage component, which can continuously stimulate the acupuncture points on the soles of the user's feet, effectively promoting blood circulation, relieving foot fatigue, and bringing better massage strength and effect.

[0009] As a preferred embodiment, two sets of massage components are rotatably mounted on the upper sides of the left and right ends of the base, and the four sets of massage components are driven to rotate by the same set of driving mechanisms. The above structure improves the comprehensiveness of massage.

[0010] Preferably, the base is provided with a support shaft extending upward, and the massage component is a disc structure which is rotatably mounted on the support shaft.

[0011] Preferably, a heating pad is provided at the upper end of the base in the area between the massage components at the left and right ends, and a heating sheet is provided at the upper end of the support shaft, and the heating sheet can transfer heat to the massage components and the massage bumps. With the above structure, the heating function can make the blood circulation of the feet smoother, thereby enhancing the massage effect.

[0012] Preferably, a toothed disc is fixedly provided on the lower side of the massage component, and the driving mechanism can drive each toothed disc to rotate.

[0013] Preferably, the driving mechanism comprises a motor disposed in the middle of the base and an output component fixedly sleeved on the output shaft of the motor, the driving mechanism further comprises a gear set rotatably disposed on the base, and the output component and the toothed disc are connected by a transmission through the gear set;

[0014] The gear sets are provided with two sets, which are respectively located on both sides of the motor output shaft.

[0015] Preferably, the gear set comprises a first gear and a second gear which are coaxially arranged, the first gear is in transmission connection with the output component, the second gear is in transmission connection with the gear plate via a third gear, the first gear and the second gear are rotatably mounted in the base via a first rotating shaft, and the third gear is rotatably mounted in the base via a second rotating shaft.

[0016] As a preferred embodiment, two groups of massage bumps are symmetrically arranged on the massage component along its circumferential direction. With the above structure, the two groups of massage bumps rotate with the massage component, and can massage the sole of the foot at different angles and positions, thereby increasing the range and flexibility of massage.

[0017] Preferably, an upper cover is provided on the base, and an opening adapted to the massage component is provided on the upper cover, wherein the opening is used to allow the massage protrusions on the massage component to protrude from the surface of the upper cover.

[0018] The second object of the present invention is to provide a car seat, including a backrest, the key of which is that the above-mentioned rotary foot massage device is flipped and installed on the back side of the backrest, and the rotary foot massage device has a folded state and an unfolded state. In the folded state, the rotary foot massage device is attached to the back side of the backrest, and in the unfolded state, the rotary foot massage device is in a downward tilted posture.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The rotary foot massage device provided by the present invention is used. The driving mechanism drives the massage component to rotate. The massage bumps on the massage component can fully and specifically stimulate the acupuncture points on the sole of the foot, more effectively promoting blood circulation, relieving foot fatigue, and bringing better massage strength and effect. On the other hand, the massage component is designed to be rotatably mounted on the base, which can make the massage component perform horizontal rotation in the horizontal plane where the sole of the foot is located. Therefore, the massage component can be made as thin as possible, making the overall structure of the massage device thinner and lighter, not occupying additional space in the car, and can be adapted to different types of car seats, with the technical advantages of simple and flexible installation.

[0021] 2. The rotating foot massage device has a heating function. When performing foot massage, the heating function can make the blood circulation in the feet smoother and the muscles better relaxed, thereby enhancing the effect of the massage, allowing users to have a more comfortable and pleasant experience and relieve driving fatigue.

[0022] 3. On the same massage component, by designing two sets of massage bumps with different heights, the higher massage bumps can focus on stimulating the acupuncture points deeper in the sole of the foot, while the lower massage bumps can stimulate the acupuncture points closer to the surface of the sole of the foot. Massage bumps of different heights will produce different pressure and rhythm changes during the massage process, thereby bringing users a richer massage experience, thereby achieving a better overall relaxation effect.

[0023] 4. By adopting the car seat provided by the present invention, the rotary foot massage device is flipped and installed on the back of the backrest. When the massage device is not in use, the rotary foot massage device can be folded on the back of the backrest and does not occupy the space inside the car, thereby ensuring the user's activity space. When foot massage is needed, the rotary foot massage device can be unfolded backwards to relax the soles of the feet. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention is further described below in conjunction with embodiments and drawings.

[0032] like Figure 1 and 7 As shown, a car seat includes a backrest A, and a rotary foot massage device is installed on the back side of the backrest A. The rotary foot massage device has a folded state and an unfolded state. In the folded state, the rotary foot massage device can fit on the back side of the backrest. In the unfolded state, the rotary foot massage device is tilted downward to facilitate the user to use the rotary foot massage device. In this embodiment, the back side of the backrest A has a receiving groove A1 adapted to the structure of the rotary foot massage device. With such a design, when the rotary foot massage device is folded on the back side of the backrest A, it can form a whole with the backrest A, does not occupy the space in the car, and has the advantage of good appearance integrity.

[0033] Please refer to Figure 1 A rotary foot massage device includes a base 1, and massage components 2 are rotatably mounted on the upper sides of both left and right ends of the base 1. The massage components 2 located on the upper sides of the left and right ends are used to massage the left and right legs of the user respectively. A massage convex block 2a is provided on the top of the massage component 2, and the massage convex block 2a is offset to one side relative to the rotation center line of the massage component 2. Figure 3 As shown, a driving mechanism 3 is provided on the base 1, and the driving mechanism 3 can drive the massage component 2 to rotate in a horizontal plane where the sole of the foot is located.

[0034] Based on the above structural design, the driving mechanism 3 drives the massage component 2 to perform horizontal rotational motion, and the massage protrusion 2a rotates with the massage component 2, which can continuously stimulate the acupuncture points on the sole of the user's foot, effectively promote blood circulation, relieve foot fatigue, and bring better massage strength and effect. On the other hand, the massage component 2 adopts a structural design of horizontal rotation installation on the base 1, which can make the massage component 2 thinner, making the overall structure of the massage device thinner and lighter, not occupying additional space in the car, and can be adapted to different types of car seats, with the technical advantages of simple and flexible installation.

[0035] like Figure 1 and Figure 5As shown, the base 1 is provided with an upwardly extending support shaft 1a, and the massage component 2 is a disc structure, which is rotatably mounted on the support shaft 1a, and the driving mechanism 3 can drive the massage component 2 to rotate around the axis of the support shaft 1a. In this embodiment, two sets of massage components 2 are rotatably installed on the upper sides of the left and right ends of the base 1, and the four sets of massage components 2 are driven to rotate by the same set of driving mechanisms 3, that is, the massage components 2 and the support shaft 1a are provided with four groups, and they correspond one to one. The four groups of massage components 2 are symmetrically arranged in pairs at both ends of the width direction of the base 1, and the two groups of massage components 2 at the same end are arranged along the length direction of the base 1. Such a design ensures that the front and back parts of the sole can be effectively massaged, thereby improving the comprehensiveness of the massage. In this embodiment, the orientation of the rotary foot massage device refers to the orientation of the car seat, such as the width direction of the base 1 corresponds to the width direction of the car seat.

[0036] Reference Figure 2 and 5 A heating pad 5 is provided at the upper end of the base 1 in the area between the massage components 2 at the left and right ends, and a heating sheet 6 is provided at the upper end of the support shaft 1a, which can transfer heat to the massage component 2 and the massage convex block 2a. When performing a foot massage, the heating function can make the blood circulation of the foot smoother and the muscles more relaxed, thereby enhancing the massage effect, allowing users to have a more comfortable and pleasant experience and relieve driving fatigue.

[0037] For details, please refer to Figure 1 and 2 The base 1 is provided with an upper cover 4, which is used to cover the internal parts of the device. The upper cover 4 is provided with openings 4a at positions corresponding to the massage components 2, and the openings 4a are adapted to the contours of the massage components 2, and the massage components 2 can rotate relative to the openings 4a, and the massage protrusions 2a can protrude upward from the surface of the upper cover 4. The heating pad 5 is arranged on the upper surface of the upper cover 4 and is located in the middle of the upper cover 4, that is, between the openings 4a at the left and right ends of the upper cover 4.

[0038] In order to ensure the wear resistance of the heating pad 5 for long-term use, in the present embodiment, the heating pad 5 is a layered structure (not shown in the figure) with a wear-resistant surface layer. In the structure of the heating pad 5, the heating layer uses graphene material to generate heat. Considering this, the heating pad 5 has the advantages of fast heating, uniform temperature and good comfort. It has high stability and aging resistance, and also has multiple protection functions such as over-temperature protection and short-circuit protection. In addition to the above-mentioned embodiment, the heating layer of the heating pad 5 can also generate heat using a resistance wire.

[0039] like Figure 5As shown, for the convenience of installation, the support shaft 1a has a hollow chamber 1a1 inside, and the heating plate 6 is installed on the top of the hollow chamber 1a1, which can transfer heat to the massage component 2 and the massage bump 2a by heat conduction, and cooperate with the heating pad 5 on the upper cover 4, so that the sole of the foot can be heated without dead angles during the massage process, which further promotes blood circulation in the foot and enhances the massage effect.

[0040] Please refer to Figure 3 and 5 A toothed disc 1b is fixedly provided on the lower side of the massage component 2, and the toothed disc 1b is rotatably mounted on the corresponding support shaft 1a through a bearing. The driving mechanism 3 can drive each toothed disc 1b to rotate synchronously, thereby driving each massage component 2 to rotate synchronously.

[0041] Further, refer to Figure 3 The driving mechanism 3 includes a motor 3a disposed in the middle of the base 1 and an output component 3b fixedly sleeved on the output shaft of the motor 3a. The driving mechanism 3 also includes a gear set 31 rotatably disposed on the base 1. The output component 3b and the toothed disc 1b are connected by transmission through the gear set 31. In this embodiment, the gear set 31 is provided with two groups, and the two groups of gear sets 31 are respectively located on the left and right sides of the output shaft of the motor 3a. The motor 3a drives the output component 3b to rotate, that is, it can drive each toothed disc 1b to rotate synchronously under the transmission action of the gear sets 31 on both sides. By designing the gear set 31, the layout flexibility and designability of the entire driving mechanism can be increased.

[0042] The two gear sets 31 are arranged symmetrically, so only one of the gear sets 31 is taken as an example for detailed description. Figures 3 to 5 As shown, the base 1 is rotatably mounted with a first rotating shaft 1c and a second rotating shaft 1d extending vertically upward, and the gear set 31 includes a first gear 3c and a second gear 3d arranged coaxially, wherein the first gear 3c is in transmission connection with the output component 3b, and the second gear 3d is in transmission connection with the two toothed discs 1b on the same side through the third gear 3e. The first gear 3c and the second gear 3d are rotatably mounted in the base 1 through the first rotating shaft 1c, and the third gear 3e is rotatably mounted in the base 1 through the second rotating shaft 1d. In this embodiment, the output component 3b is a worm, the first gear 3c is a worm wheel, and the output component 3b and the first gear 3c constitute a worm and worm wheel transmission. The rotation of the output component 3b drives the first gear 3c to rotate, thereby driving the second gear 3d to rotate, and the second gear 3d can be transmitted to the corresponding third gear 3e, and the rotation of the third gear 3e can drive the two sets of toothed discs 1b on the same side to rotate, thereby driving the four groups of massage components 2 to rotate synchronously. The same motor 3a can realize the synchronous rotation of the massage components 2 through the above gear layout, which has the technical advantages of traditional stability and compact and reasonable structural layout.

[0043] Reference Figure 1 and5 Two groups of massage protrusions 2a are symmetrically arranged on the massage component 2 along its circumferential direction. When the massage component 2 rotates, the two groups of massage protrusions 2a are driven to rotate accordingly, so that the two groups of massage protrusions 2a can massage the sole of the foot at different angles and positions, thereby increasing the range and flexibility of massage.

[0044] Depend on Figure 5 It can be seen that on the same massage component 2, the two groups of massage bumps 2a have a height difference, that is, the two groups of massage bumps 2a have different structural sizes. With such a design, the higher massage head can focus on stimulating the acupuncture points at deeper positions on the sole of the foot, while the lower massage head can stimulate the acupuncture points closer to the surface of the sole of the foot. Massage heads of different heights will produce different pressures and rhythm changes during the massage process, thereby bringing users a richer massage experience, thereby achieving a better overall relaxation effect.

[0045] Please refer to Figure 6 and 7 The rotary foot massage device also includes a shell structure 7, which has an installation space 7a inside which can accommodate the base 1. The base 1 is fixedly assembled in the installation space 7a, and the shell structure 7 is flippably arranged on the rear side of the backrest A.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention, and such changes all fall within the scope of protection of the present invention.
