[0048] The present invention is further described below in conjunction with embodiments and drawings.

[0049] like Figure 1 and 2 A car seat shown in the figure includes a backrest 7, and a car foot massage device A is installed on the rear side of the backrest 7. A sinking area 71 adapted to the outer contour of the car foot massage device A is provided on the rear side of the backrest 7. When the massage device is not in use, the car foot massage device A is rotated and folded in the sinking area 71 to form a whole with the rear side of the backrest 7, without occupying additional space in the car, and its appearance is well integrated. When the car foot massage device A is needed, the car foot massage device A is rotated downward, and the car foot massage device A can be flipped and unfolded to the rear side of the backrest 7 in a downward tilted state, so that the rear passengers can perform foot massage. In actual application, the rotation of the car foot massage device A relative to the backrest 7 can be operated manually or electrically. The structure of the car foot massage device A will be described in detail below. In this embodiment, the orientation of the car foot massage device A is described with reference to the car seat, such as: the width direction of the support base 1 corresponds to the width direction of the car seat.

[0050] Please refer to Figure 4 A vehicle foot massage device A comprises a support base 1, a driving mechanism 4 and two groups of massage sets 2 arranged on the support base 1, wherein the two groups of massage sets 2 are respectively arranged in the left area and the right area of ​​the support base 1, that is, the two groups of massage sets 2 are respectively used to massage the left leg foot and the right leg foot of the user. The two groups of massage sets 2 have the same structure, so only the structure of one group of massage sets 2 is described in detail. The massage set 2 comprises a first massage component 21 rotatably arranged on the support base 1, and the driving mechanism 4 can drive the first massage component 21 to rotate. In this embodiment, the two groups of first massage components 21 share a set of driving mechanisms 4. When the sole of the user's foot is pressed on the first massage component 21, the first massage component 21 can stimulate the sole of the user's foot in a rolling and rotating manner.

[0051] Based on the above structural design, when the vehicle foot massage device A is needed, the user flips the vehicle foot massage device A manually or electrically so that the vehicle foot massage device A is tilted downward relative to the rear side of the backrest 7, and then presses the sole of the foot on the first massage component 21. The driving mechanism 4 drives the first massage component 21 to rotate, and the first massage component 21 can stimulate the sole of the user's foot in a rolling and rotating manner, thereby achieving the purpose of effective massage.

[0052] Further, refer to Figure 5 , the first massage component 21 is arranged at the front of the support base 1, and the massage set 2 also includes a second massage component 22 arranged at the middle, middle rear or rear of the support base 1, and the second massage component 22 can massage the sole of the user's foot in a forward and backward movement. The second massage component 22 and the first massage component 21 can be linked, that is, when the first massage component 21 rotates, it can drive the second massage component 22 to move forward and backward to achieve massage stimulation of the corresponding area of ​​the sole. When the second massage component 22 is arranged at the middle rear or rear of the support base 1, in conjunction with the first massage component 21, the massage set 2 can achieve rolling massage of the front of the sole and scraping and kneading massage of the middle and rear of the sole, with the advantages of good massage effect and comprehensive massage.

[0053] Depend on Figure 5 It can be seen that in this embodiment, the second massage component 22 is arranged in the middle of the support base 1, and the massage set 2 also includes a third massage component 23 arranged in the rear of the support base 1 in a forward and backward movement manner, and the third massage component 23 can be linked with the second massage component 22. That is, when the first massage component 21 rotates, it can drive the second massage component 22 and the third massage component 23 to move forward and backward synchronously, thereby achieving massage stimulation corresponding to the front, middle and rear parts of the sole.

[0054] Based on this, the first massage component 21, the second massage component 22 and the third massage component 23 are connected in sequence to form a complete massage set 2, which can accurately perform targeted massage on the front, middle and back of the user's foot, thereby providing the user with a more comprehensive and comfortable massage experience. Secondly, by linking the second massage component 22 with the first massage component 21, and the third massage component 23 with the second massage component 22, the drive mechanism 4 only needs to drive the first massage component 21 to rotate, that is, it can drive the second massage component 22 and the third massage component 23 to move forward and backward synchronously. Under the synergistic effect of the drive mechanism 4 and the above-mentioned linkage, only one main drive mechanism 4 is needed to transmit power to each massage component through linkage. Compared with equipping each massage component with an independent drive mechanism 4, the number of drive devices is greatly reduced, making the overall structure of the device more concise and compact, and reducing the complexity of design and manufacturing. Through linkage transmission, the movement of the three massage components can be ensured to be highly coordinated and synchronized, so that the rolling massage of the front of the foot, the scraping and kneading massage of the middle of the foot, and the massage of the back of the foot can be performed in a specific order and rhythm, better simulating the techniques and strength changes of manual massage, and providing users with a more comfortable, coherent and effective massage experience.

[0055] For further information, see Figure 5 and 6 The first massage component 21 is constructed as a roller structure, and a first massage protrusion 211 is distributed on its circumferential surface. When the first massage component 21 rotates, the first massage protrusion 211 on its surface can continuously roll the forefoot. The rolling massage method of the first massage component 21 can fit the physiological structure of the forefoot well, and can perform rolling stimulation on the surrounding areas of the forefoot such as the toe joints and Yongquan acupoints, which can effectively relax the toe muscles and promote local blood circulation. The second massage component 22 has a second massage protrusion 221 distributed on the upper surface. The second massage component 22 moves back and forth, and the second massage protrusion 221 on its surface can perform scraping massage on the middle part of the user's foot. There are many important acupuncture points and reflex areas in the middle part of the foot, and the scraping and kneading massage of the second massage component 22 can accurately act on these parts. The third massage component 23 has a third massage protrusion 231 distributed on the upper surface. The third massage component 23 moves back and forth, and the third massage protrusion 231 on its surface can massage and stimulate the back of the user's foot back and forth.

[0056] The massage set 2 has three massage components that act on the front, middle and back of the foot respectively, achieving full coverage of the entire foot, and can provide all-round massage care from toes to heels, avoiding the situation where certain areas of the foot are not effectively massaged, and providing users with a comprehensive and systematic foot massage experience. On the other hand, the combination of multiple massage techniques can make the foot feel different forms of force and stimulation, which can not only relax muscles and relieve fatigue, but also promote the smooth flow of meridians in the foot, achieving better health care effects.

[0057] like Figure 6 and 7 As shown, the upper surface of the second massage component 22 is configured as an arc-shaped structure. Such a structural design is more in line with the structure of the middle part of the human foot, thereby enhancing the massage effect.

[0058] Reference Figure 7 In this embodiment, a plane structure 212 is provided on one radial side of the first massage component 21, and the first massage protrusions 211 are distributed on the arc surface of the circumferential surface of the first massage component 21. With such a design, in the initial state, the plane structure 212 faces upward, so that the first massage component 21 is folded inside the massage device as a whole, ensuring the compactness of the product. When the first massage component 21 rotates, Fig.10 The first massage protrusions 211 on its surface can protrude upwards and act on the front part of the user's foot.

[0059] like Figure 6 and 8 As shown, the second massage component 22 is provided with a first linkage component 31 extending forward, and the front end of the first linkage component 31 is eccentrically connected to the first massage component 21. The side of the second massage component 22 is provided with a first limiting hole 222, and the support base 1 is fixed with a first limiting pin 12 extending along its width direction, and the first limiting hole 222 can be slidably mounted on the first limiting pin 12. Fig.11 As shown, the first limiting hole 222 plays a guiding and limiting role. The first massage component 21 rotates, and under the coordinated action of the first linkage component 31, the first limiting hole 222 and the first limiting pin 12, the second massage component 22 can be driven to reciprocate back and forth.

[0060] Furthermore, Figure 6 and 8 As shown, the third massage component 23 is provided with a second linkage component 32 extending forward, and the front end of the second linkage component 32 is rotatably connected to the rear end of the second massage component 22. Figure 5 and 11 As shown, a second limiting hole 232 is provided in the middle of the third massage component 23, and a second limiting pin 13 extending in the width direction thereof is fixedly provided on the support base 1, and the second limiting hole 232 can be slidably supported on the second limiting pin 13. The second limiting hole 232 plays a guiding and limiting role, and the second massage component 22 slides forward and backward, and can move forward and backward under the coordinated action of the second linkage component 32, the second limiting hole 232 and the second limiting pin 13.

[0061] In this embodiment, the first limiting hole 222 is a strip-shaped structure arranged obliquely. When the second massage component 22 slides forward and backward, that is, when the first limiting hole 222 arranged obliquely slides forward and backward along the first limiting pin 12, the second massage component 22 will have a height change. The purpose of such a design is that when the massage device is not in use, the second massage component 22 can be folded inside the device as a whole, and when in use, the second massage protrusion 221 on the second massage component 22 can protrude upward, thereby stimulating the user's foot.

[0062] Furthermore, in this embodiment, the second limiting hole 232 is an arc-shaped hole arranged obliquely. Such a structural design enables the third massage component 23 to press upwards while moving forward and backwards, thereby realizing the upward pressing function of the third massage component 23 on the rear of the foot. In addition, because the limiting hole is arranged obliquely, it can also ensure that the corresponding massage component is in a low position when folded, ensuring the compactness of the product.

[0063] Please refer to Figure 5 A rotating shaft 11 is rotatably mounted on the support base 1, and the rotating shaft 11 is arranged to extend along the width direction of the support base 1, and the first massage components 21 of the two massage sets 2 are fixedly sleeved on both ends of the rotating shaft 11. The driving mechanism 4 is arranged in the middle area of ​​the support base 1, and the driving mechanism 4 can drive the rotating shaft 11 to rotate, thereby driving the first massage components 21 of the two massage sets 2 to rotate synchronously.

[0064] To achieve the feasibility of connection, refer to Figure 5 and Figure 8 In this embodiment, in the same massage set 2 , two first massage components 21 are provided, the two first massage components 21 are spaced apart on the rotating shaft 11 , and the front end of the first linkage component 31 is located between the two groups of first massage components 21 .

[0065] like Figure 5 and 6 As shown, the driving mechanism 4 includes a motor 41 fixed on the supporting base 1, an output component 42 is sleeved on the output shaft of the motor 41, and a first gear 43 is sleeved on the rotating shaft 11. The motor 41 drives the output component 42 to directly or indirectly drive the first gear 43 to rotate. In this embodiment, the output component 42 drives the first gear 43 to rotate by an indirect driving method, which is as follows: Fig. 9The output component 42 is a worm, and a transmission assembly is provided between the output component 42 and the first gear 43. The transmission assembly includes a transmission shaft 44 rotatably arranged above the output component 42, and a transmission gear 45 and a linkage gear 46 are fixedly sleeved on the transmission shaft 44 along its axial interval, wherein the transmission gear 45 meshes with the output component 42, and the linkage gear 46 meshes with the first gear 43. The motor 41 drives the output component 42 on the output shaft to rotate, which can drive the transmission gear 45 to rotate, and transmits the transmission to the linkage gear 46 on the transmission shaft 44. The rotation of the linkage gear 46 can drive the first gear 43 to rotate. Such a design increases the stability of the transmission.

[0066] Please refer to Figure 3 The support base 1 is provided with a dorsal cover 5, and the user's foot can be inserted into the dorsal cover 5 in the manner of wearing slippers. After the user inserts the foot into the dorsal cover 5, the dorsal cover 5 can keep the foot stably on the vehicle foot massage device to enhance the massage effect.

[0067] Further, refer to Fig.13 and 14 , one end of the instep cover 5 is fixedly connected to the support base 1 through an elastic structure 52. Considering this, when the massage function is not used, the instep cover 5 covers the surface of the massage device through the elastic tension of the elastic structure 52 to make the surface of the massage device smooth. When in use, the user's foot can overcome the tension of the elastic structure 52 to stretch the instep cover 5 upward. Such a structural design is also suitable for feet of different sizes to meet the needs of users of different body shapes. In this embodiment, the instep cover 5 is extended along the width direction of the support base 1, the middle part of which is fixed to the middle part of the support base 1, and the two ends of the instep cover 5 extend to the left and right sides of the support base 1 respectively, and the two ends of the instep cover 5 are fixedly connected with the elastic structure 52, and the two elastic structures 52 are respectively located at the left and right ends of the bottom of the support base 1. Such a design can meet the needs of fixing the left and right feet of the user.

[0068] Re-attend Fig.13 and 15 An inflatable interlayer 51 is provided inside the instep cover 5, and an air pump for inflating the inflatable interlayer 51 is provided on the support base 1, and the air pump is powered by the motor 41. When the user's foot is inserted into the instep cover 5, the air pump inflates the inflatable interlayer 51, providing downward pressure on the instep, so that the foot can be pressed on the massage device, further improving the massage effect of the foot massage.

[0069] Please refer to Fig.12 and 16, an isolation plate 8 is fixedly provided on the upper side of the support base 1, and the isolation plate 8 is provided with openings 81 in the areas corresponding to the two groups of massage sets 2. When the massage function is not in use, the various massage components of the massage set 2 are located at the lower side of the opening 81. When the foot massage function is enabled, the various massage components move, and the massage protrusions on the massage components can protrude upward from the opening 81. Furthermore, in order to improve the durability of the massage device and the comfort of the user's sole contacting the device, a sole cover 82 adapted to its structure is fixedly provided on the isolation plate 8, and the two openings 81 are covered with mesh cloth 83. With such a structural design, the mesh cloth 83 can prevent foreign matter from entering the interior of the massage device and protect the massage device. At the same time, the mesh cloth 83 is soft in texture and has a certain elasticity. It can protect the sole skin to a certain extent during the massage process and increase the comfort of the massage.

[0070] like Figure 1 and 3 As shown, an upper cover plate 6 is rotatably mounted on the support base 1, and the upper cover plate 6 can be opened by an unlocking button. The upper cover plate 6 not only protects the vehicle foot massage device, but also, when the massage function is not used, the vehicle foot massage device can be turned downward to be used as a footrest for rear passengers, which has the advantages of strong practicality and high space utilization.

[0071] Finally, it should be noted that the above description is only a preferred embodiment of the present invention.
