When the leg massage function is enabled, as Figures 5 to 7 shown, the swinging driving mechanism 4 drives the rocker structure 3 to reciprocally swing around the rotation center thereof and the leg support assembly 1, at this time, the massage component 2 at the end of the rocker structure 3 can make a semicircular reciprocating motion towards the upper side of the leg support assembly 1, that is, it can massage the user's shank back and forth in a scraping and rubbing manner, deep layer muscle fatigue of the leg is relieved, and the advantage of good massage effect is achieved. In addition, the motion track of the massage component 2 is semicircular, that is, the massage component 2 only moves in the direction of the upper side of the leg support assembly 1, and does not interfere with the internal structure of the leg support assembly 1, and the advantages of simple overall structure and good overall appearance are achieved.

[0037] As Figure 1 and 3 shown, the massage component 2 is a cylindrical roller, the surface of the cylindrical roller is distributed with massage protrusions 21, the cylindrical roller is rotatably mounted at the distal end of the rocker structure 3, and the rotation center line of the cylindrical roller is arranged along the width direction of the leg support assembly 1. In this embodiment, the positional concept of the leg support assembly 1 is based on the automobile seat, that is, the width direction of the leg support assembly 1 corresponds to the width direction of the automobile seat. In this way, during massage, referring to Figure 6 , the cylindrical roller scrapes and rubs back and forth along the back side of the user's shank B, and the massage protrusions 21 thereof can act on the deep layer muscle of the user's shank B, and the massage effect is further improved.

[0038] Further, as shown in Figure 5 The middle part of the rocker structure 3 is rotatably connected with the leg supporting assembly 1, so that an outwardly extending driving handle 33 is formed at the end of the rocker structure 3 away from the massage component 2, and the rocking driving mechanism 4 can drive the driving handle 33 to reciprocating rotate. In combination Figure 6 And 7 As shown in The rocking driving mechanism 4 drives the driving handle 33 to reciprocating rotate towards the bottom of the leg supporting assembly 1, so as to drive the massage component 2 at the upper end of the rocker structure 3 to reciprocating swing towards the top of the leg supporting assembly 1, thereby achieving the massage effect of back and forth scraping and rubbing.

[0039] Please refer to Figure 2 And 3 The rocking driving mechanism 4 includes a rotating shaft 41 arranged on the leg supporting assembly 1 and a motor 42, the motor 42 can drive the rotating shaft 41 to rotate, and a linkage assembly is arranged between the rotating shaft 41 and the outer end of the driving handle 33. The motor 42 drives the rotating shaft 41 to rotate, which can drive the driving handle 33 to reciprocating rotate under the linkage action of the linkage assembly.

[0040] Further, please refer to Figure 2 And 3 The linkage assembly includes a linkage piece 43 fixedly arranged on the rotating shaft 41, the linkage piece 43 extends radially outward along the rotating shaft 41, and the end of the linkage piece 43 away from the rotating shaft 41 is hingedly connected with a connecting rod 44, and the end of the connecting rod 44 away from the linkage piece 43 is hingedly connected with the end of the outer end of the driving handle 33. In this embodiment, the connecting rod 44 is in an arc structure.

[0041] Based on this, the rocker structure 3, the connecting rod 44 and the linkage piece 43 constitute a crank and rocker mechanism, the motor 42 drives the rotating shaft 41 to rotate, which drives the linkage piece 43 to rotate around the rotating shaft 41, and through the transmission action of the connecting rod 44, the rocker structure 3 can be driven to reciprocating swing around the rotation center of the rocker structure 3 and the leg supporting assembly 1, thereby realizing the semicircular motion track of the massage component 2 and achieving the purpose of back and forth scraping and rubbing massage (refer to Figures 5 to 7 ). Such connection structure has the advantages of small stress and stable mechanism motion.

Specifically, the number of rotating shafts 41 is two groups, both of which are arranged along the width direction of the leg rest assembly 1, and the massage components 2, rocker structures 3, and linkage assemblies are all provided with four groups and correspond one by one. The four groups of linkage assemblies are located at the four end positions of the two groups of rotating shafts 41, that is, the four groups of linkage plates 43 are respectively located at the four end positions of the two groups of rotating shafts 41. Among them, the two massage components 2 at the left end of the two groups of rotating shafts 41 are used to massage the left lower leg of the user, and the two massage components 2 at the right end of the two groups of rotating shafts 41 are used to massage the right lower leg of the user.

[0043] Further, the adjacent two groups of massage components 2, rocker structures 3, connecting rods 44, and linkage plates 43 are symmetrically arranged, and the rotating directions of the two groups of rotating shafts 41 are opposite. Referring to Figure 1 and Figure 5 Taking the two massage components 2 on the right side of the leg rest assembly 1 as an example, the two massage components 2 correspond to the upper part and the lower part of the back of the lower leg respectively. In use, as shown in Figures 5 to 7 , the motor 42 drives the rotating shaft 41 at the upper part to rotate counterclockwise, and the massage component 2 at the upper part can move back and forth reciprocatingly from front to up and then to back, that is, the massage component 2 rubs and kneads back and forth from the upper part to the middle part of the back of the lower leg. Since the adjacent two groups of massage components 2, rocker structures 3, connecting rods 44, and linkage plates 43 are symmetrically arranged, and the rotating directions of the two groups of rotating shafts 41 are opposite, the motor 42 drives the rotating shaft 41 at the lower part to rotate clockwise, and the massage component 2 at the lower part can move back and forth reciprocatingly from back to up and then to front, that is, the massage component 2 rubs and kneads back and forth from the lower part to the middle part of the back of the lower leg. Such a massage mode can bring the user a more in-depth massage experience, further improving the leg massage effect and effectively relieving the user's fatigue.

[0045] Please refer to FIG. 2 and 3, taking one set of rocker structure 3 and corresponding massage component 2 as an example, the rocker structure 3 comprises two connecting brackets 31 symmetrically arranged at two ends of the massage component 2, the massage component 2 is rotationally supported between end portions of the two connecting brackets 31, and a connecting shaft 32 is fixedly arranged between two ends of the connecting brackets 31 away from the massage component 2, both ends of the connecting shaft 32 penetrate through the two connecting brackets 31, and both ends of the connecting shaft 32 are rotationally supported on the leg supporting assembly 1. A driving handle 33 is fixedly arranged on the connecting shaft 32 and extends outward, and an end of the connecting rod 44 away from the linkage plate 43 is hingedly connected to an outer end of the driving handle 33, that is, an end of the driving handle 33 away from the connecting shaft 32. In this way, the two connecting brackets 31, the connecting shaft 32 and the driving handle 33 constitute the rocker structure 3, and the motor 42 drives the linkage plate 43 to rotate around the rotating shaft 41, which can drive the two connecting brackets 31 to do semicircular reciprocating swing with the connecting shaft 32 as the fulcrum under the transmission of the connecting rod 44.

[0046] In order to ensure the reliability and stability of the mechanism movement, the driving handle 33 is arranged in the middle of the connecting shaft 32.

[0047] Please refer to Figure 1 and 4 The leg supporting assembly 1 is provided with an opening 11 corresponding to the position of each of the four massage components 2, and the opening 11 can avoid the reciprocating upward movement of the massage component 2, so that the massage protrusions 21 on the massage component 2 can effectively act on the back side of the user's lower leg.
