Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, and in particular to a leg scraping and massaging device and an automobile seat with the device. Background Art

[0002] In order to relieve users' physical fatigue and discomfort caused by long-term driving or riding, some car seats have added massage functions. Among them, for calf massage, a massage mechanism is usually set on the surface of the seat leg support to relieve occupants' leg fatigue.

[0003] In the prior art, the massage mechanism arranged on the surface of the leg rest is divided into an air bag massage mechanism and a roller massage mechanism. Although the air bag massage mechanism occupies a small space, it can only perform a point-pressure massage, and the strength and massage effect are poor. The current roller massage mechanism, on the other hand, achieves the purpose of massage and relief by rotating the roller so that the massage protrusions on the surface of the roller continuously act on the back of the user's calf. Although it has certain advantages in strength compared to the air bag massage mechanism, its massage stroke is short, and in order to accommodate the activity space of the roller, the thickness of the leg rest needs to be increased, which has a great impact on the structure of the leg rest and the overall structure of the seat. Summary of the invention

[0004] In view of this, one of the purposes of the present invention is to provide a leg scraping and kneading massage device, which has the advantages of good massage effect and compact overall structure.

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

[0007] The leg rest assembly is provided with a swing drive mechanism, which is used to drive the rocker arm structure to swing back and forth. During the reciprocating swing of the rocker arm structure, the massage component at its far end can alternately switch between being stored inside the leg rest assembly and protruding from the upper surface of the leg rest assembly.

[0008] With the above structure, the swing drive mechanism drives the rocker arm structure to swing back and forth around the rotation center of the rocker arm and the leg rest assembly. At this time, the massage component at the end of the rocker arm structure can make a semicircular reciprocating motion toward the top of the leg rest assembly, that is, it can massage the user's calf back and forth in a scraping and kneading manner, deeply relieving leg muscle fatigue and having the advantage of good massage effect.

[0009] Preferably, the massage component is a cylindrical roller with massage protrusions distributed on its surface. The cylindrical roller is rotatably mounted at the far end of the rocker arm structure, and the rotation centerline of the cylindrical roller is arranged along the width direction of the leg support assembly.

[0010] Preferably, the middle portion of the rocker arm structure is rotatably connected to the leg support assembly so that an outwardly extending driving handle is formed at one end of the rocker arm structure away from the massage component, and the rocking drive mechanism is used to drive the driving handle to reciprocate.

[0011] Preferably, the swing drive mechanism comprises a rotating shaft arranged on the leg support assembly, and a motor driving the rotating shaft to rotate, and a linkage assembly is arranged between the rotating shaft and the outer end of the driving handle;

[0012] The motor drives the rotating shaft to rotate, and can drive the driving handle to reciprocate under the linkage action of the linkage assembly.

[0013] Preferably, the linkage assembly comprises a linkage plate fixed on the rotating shaft, the linkage plate extends radially outward along the rotating shaft, one end of the linkage plate away from the rotating shaft is hinged with a connecting rod, and one end of the connecting rod away from the linkage plate is hinged to the end of the driving handle.

[0014] Preferably, the rocker arm structure comprises connecting brackets symmetrically arranged at both ends of the massage component, the massage component is rotatably supported between the ends of the two connecting brackets, a connecting shaft is fixedly arranged between the ends of the two connecting brackets away from the massage component, and both ends of the connecting shaft are rotatably supported on the leg support assembly; the driving handle is fixedly arranged on the connecting shaft and extends outward, and the end of the connecting rod away from the linkage plate is hinged to the end of the driving handle;

[0015] The motor drives the linkage piece to rotate around the rotating shaft, and can drive the two connecting brackets to swing back and forth with the connecting shaft as a fulcrum under the transmission effect of the connecting rod.

[0016] Preferably, four groups of the massage components and four groups of rocker arm structures associated therewith are rectangularly distributed on the leg rest assembly, and the four groups of rocker arm structures share one set of the rocking drive mechanism.

[0017] Preferably, there are two groups of rotating shafts, both of which are arranged along the width direction of the leg rest assembly; the massage components, rocker arm structures, and linkage components are each provided in four groups and correspond one to one; the four groups of linkage components are located at the four end positions of the two groups of rotating shafts.

[0018] Preferably, the leg rest assembly is provided with openings at positions corresponding to the massage components, and the openings are used to prevent the massage components from swinging back and forth.

[0019] The second object of the present invention is to provide a car seat, including a seat frame assembly, the key of which is that the above-mentioned leg scraping and massaging device is installed on the front side of the seat frame assembly.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When the leg scraping and kneading massage device provided by the present invention is used, when the leg massage function is not used, the massage component is located on the lower side of the leg rest assembly. At this time, the upper surface of the leg rest assembly remains flat, the leg rest function can be used normally, and the user's calves do not feel uncomfortable, which has the advantage of good comfort. When the leg massage function is used, the swing drive mechanism drives the rocker arm structure to swing back and forth around the rotation center of the leg rest assembly. At this time, the massage component at the end of the rocker arm structure can make a semicircular reciprocating motion toward the top of the leg rest assembly, that is, it can massage the user's calves back and forth in a scraping and kneading manner, deeply relieve leg muscle fatigue, and has the advantage of a good massage effect. In addition, the movement trajectory of the massage component is semicircular, that is, the massage component only moves in the upper direction of the leg rest assembly, and will not interfere with the internal structure of the leg rest assembly, which has the advantages of a simple overall structure and good overall appearance.

[0022] 2. Massage by scraping and kneading can deeply relax the leg muscles and effectively relieve the user's leg fatigue.

[0023] 3. Through optimized design, the overall structure of the leg scraping and kneading massage device is compact and streamlined. When integrated on a car seat, it can take into account both the overall appearance of the seat and the effectiveness of massage. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention is further described below in conjunction with embodiments and drawings.

[0034] like Fig. 9 As shown, a car seat includes a seat frame assembly A, and a leg scraping and massaging device is installed on the front side of the seat frame assembly A. The leg scraping and massaging device can support the user's calves and scrape and massage the user's calves.

[0035] Please refer to Figure 1 and 5 The leg scraping and massaging device comprises a leg rest assembly 1 rotatably mounted to the front side of the seat frame assembly A, and a rocker structure 3 rotatably mounted on the leg rest assembly 1, and a massage component 2 is rotatably mounted on one end of the rocker structure 3 away from the eccentric end. The leg rest assembly 1 is provided with a rocking drive mechanism 4, which can drive the rocker structure 3 to swing back and forth. During the rocker structure 3 swinging back and forth, the massage component 2 at the far end thereof can alternately switch between being stored in the leg rest assembly 1 and protruding from the upper surface of the leg rest assembly 1 (refer to Figure 4 ).

[0036] Based on the above structural design, when the leg massage function is not used, the massage component 2 is located at the lower side of the leg support assembly 1. At this time, the upper surface of the leg support assembly 1 remains flat, the leg support function can be used normally, and the user's calves do not feel uncomfortable, which has the advantage of good comfort. Figures 5 to 7 As shown, the swing drive mechanism 4 drives the rocker arm structure 3 to swing back and forth around the rotation center between it and the leg rest assembly 1. At this time, the massage component 2 at the end of the rocker arm structure 3 can make a semicircular reciprocating motion toward the top of the leg rest assembly 1, that is, it can massage the user's calf back and forth in a scraping and kneading manner, deeply relieving leg muscle fatigue, and having the advantage of a good massage effect. In addition, the movement trajectory of the massage component 2 is a semicircle, that is, the massage component 2 only moves in the upper direction of the leg rest assembly 1, and will not interfere with the internal structure of the leg rest assembly 1, which has the advantages of a streamlined overall structure and a good overall appearance.

[0037] like Figure 1 and 3 As shown, the massage component 2 is a cylindrical roller with massage protrusions 21 distributed on its surface. The cylindrical roller is rotatably mounted at the far end of the rocker structure 3, and the rotation centerline of the cylindrical roller is arranged along the width direction of the leg rest assembly 1. In this embodiment, the orientation concept of the leg rest assembly 1 is based on the car seat, that is, the width direction of the leg rest assembly 1 corresponds to the width direction of the car seat. With such a design, when massaging, refer to Figure 6The cylindrical roller scrapes and rubs back and forth along the back side of the user's calf B, and its massage protrusions 21 can act on the deep muscles of the user's calf B, further improving the massage effect.

[0038] Furthermore, Figure 5 As shown, the middle part of the rocker arm structure 3 is rotatably connected to the leg support assembly 1, so that the end of the rocker arm structure 3 away from the massage component 2 is formed with a driving handle 33 extending outward, and the swing drive mechanism 4 can drive the driving handle 33 to reciprocate. Figure 6 and 7 As shown, the swing drive mechanism 4 drives the drive handle 33 to reciprocate toward the bottom of the leg rest assembly 1, which can drive the massage component 2 at the upper end of the rocker structure 3 to swing back and forth above the leg rest assembly 1, thereby achieving a back and forth scraping and kneading massage effect.

[0039] Please refer to Figure 2 and 3 The swing drive mechanism 4 includes a rotating shaft 41 and a motor 42 disposed on the leg support assembly 1. The motor 42 can drive the rotating shaft 41 to rotate. A linkage assembly is disposed between the rotating shaft 41 and the outer end of the driving handle 33. The motor 42 drives the rotating shaft 42 to rotate, and can drive the driving handle 33 to reciprocate under the linkage action of the linkage assembly.

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

[0041] Based on this, the rocker arm structure 3, the connecting rod 44 and the linkage plate 43 constitute a crank rocker mechanism, the motor 42 drives the rotating shaft 42 to rotate, and drives the linkage plate 43 to rotate around the rotating shaft 42. Through the transmission effect of the connecting rod 44, the rocker arm structure 3 can be driven to swing back and forth around the rotation center between it and the leg support assembly 1, thereby realizing the semicircular motion trajectory of the massage component 2, and achieving the purpose of scraping and kneading massage back and forth (refer to Figures 5 to 7 ). Such a connection structure has the advantages of small force and smooth mechanism movement.

[0042] like Figure 2 and 3As shown, in this embodiment, four groups of massage components 2 and four groups of rocker arm structures 3 associated therewith are arranged in a rectangular shape on the leg rest assembly 1, and the four groups of rocker arm structures 3 share a set of swing drive mechanisms 4. Specifically, there are two groups of rotating shafts 41, and both groups of rotating shafts 41 are arranged along the width direction of the leg rest assembly 1, and four groups of massage components 2, rocker arm structures 3, and linkage components are provided and correspond one to one, and the four groups of linkage components are located at the four end positions of the two groups of rotating shafts 41, that is, the four groups of linkage pieces 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 user's left calf, and the two massage components 2 at the right end of the two groups of rotating shafts 41 are used to massage the user's right calf.

[0043] Furthermore, two adjacent groups of massage components 2, rocker arm structures 3, connecting rods 44 and linkage plates 43 are symmetrically arranged, and the rotation directions of the two groups of rotating shafts 41 are opposite. Figure 1 and Figure 5 Taking the two massage components 2 on the right side of the leg support assembly 1 as an example, the two massage components 2 correspond to the upper and lower parts of the back of the calf respectively. When in use, Figures 5 to 7 As shown, the motor 42 drives the upper rotating shaft 42 to rotate counterclockwise, and the massage component 2 located at the upper part can reciprocate from front to top and then to back, that is, the massage component 2 scrapes and rubs from the upper part of the posterior side of the calf to the middle part. Since the two adjacent groups of massage components 2, the rocker arm structure 3, the connecting rod 44 and the linkage sheet 43 are symmetrically arranged, and the rotation directions of the two groups of rotating shafts 41 are opposite, the motor 42 drives the lower rotating shaft 42 to rotate clockwise, and the massage component 2 located at the lower part can reciprocate from back to top and then to front, that is, the massage component 2 scrapes and rubs from the lower part of the posterior side of the calf to the middle part. This massage method can bring users a deeper massage experience, further improve the leg massage effect, and effectively relieve user fatigue.

[0044] For example Figure 2 and 3 As shown, in order to improve the compactness of the device, in this embodiment, the motor 42 is arranged in the middle of the leg support assembly 1 and is located between the two sets of rotating shafts 41. The output shaft a of the motor 42 is connected to the transmission box 421. Figure 8 As shown, two output components 422 are provided in the transmission housing 421, and the two sets of rotating shafts 41 are respectively fixedly sleeved on the two output components 422. The output shaft a of the motor 42 and the two output components 422 can be connected by gears or other transmission components to drive the two sets of rotating shafts 41 to rotate in opposite directions.

[0045] Please refer to Figure 2 and 3Taking one set of rocker arm structures 3 and the corresponding massage component 2 as an example, the rocker arm structure 3 includes connecting brackets 31 symmetrically arranged at both ends of the massage component 2, and the massage component 2 is rotatably supported between the ends of the two connecting brackets 31. A connecting shaft 32 is fixedly arranged between the ends of the two connecting brackets 31 away from the massage component 2, and the two ends of the connecting shaft 32 pass through the two connecting brackets 31, and both ends of the connecting shaft 32 are rotatably supported on the leg support assembly 1. The driving handle 33 is fixedly arranged on the connecting shaft 32 and extends outward, and the end of the connecting rod 44 away from the linkage plate 43 is hinged to the outer end of the driving handle 33, that is, it is hinged to the end of the driving handle 33 away from the connecting shaft 32. With such a design, the two connecting brackets 31, the connecting shaft 32 and the driving handle 33 constitute the rocker arm structure 3 as a whole, and the motor 42 drives the linkage plate 43 to rotate around the rotating shaft 42, which can drive the two connecting brackets 31 to make a semicircular reciprocating swing with the connecting shaft 32 as the fulcrum under the transmission action 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 support assembly 1 is provided with openings 11 at positions corresponding to the four massage components 2. The openings 11 can prevent the massage components 2 from making upward reciprocating motion, so that the massage protrusions 21 on the massage components 2 can effectively act on the back of the user's calves.

[0048] 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.
