[0039] The utility model will be further described below in combination with the embodiments and the drawings.

[0040] As shown in Figure 14 , a seat comprises a backrest A, and a knocking and kneading massage device C with a common motor is integrally installed inside the backrest A. Referring to Figure 1 and 2 , the specific structure of the knocking and kneading massage device C with the common motor is as follows: it comprises a base 1, in this embodiment, the base 1 comprises a mounting base plate 1a and a support plate 1b which is slidingly assembled on the mounting base plate 1a, the mounting base plate 1a is assembled inside the backrest A, and the support plate 1b can slide along the height direction of the mounting base plate 1a. The support plate 1b is provided with a rotating shaft 2 and a driving mechanism 3 which drives the rotating shaft 2 to rotate, wherein the rotating shaft 2 is connected with two groups of massage swing arms 4, the two groups of massage swing arms 4 are the same in structure and are symmetrically arranged along the width direction of the support plate 1b (the width direction of the support plate 1b corresponds to the width direction of the automobile seat). The massage swing arm 4 has a proximal end which is sleeved on the rotating shaft 2 and a distal end which extends radially outward along the rotating shaft 2, and the distal end of the massage swing arm 4 is provided with a massage head 4a. A retaining rod 6 is connected between the middle part of the massage swing arm 4 and the base 1, and the retaining rod 6 and the massage swing arm 4 and / or the retaining rod 6 and the base 1 are in a rotating connection relationship. The driving mechanism 3 drives the rotating shaft 2 to rotate forward, which can force the proximal end of the massage swing arm 4 to reciprocate along the axis of the rotating shaft 2, so as to make the massage head 4a at the distal end form a kneading massage. The driving mechanism 3 drives the rotating shaft 2 to rotate reversely, which can force the proximal end of the massage swing arm 4 to eccentrically swing relative to the rotating shaft 2, so as to make the massage head 4a at the distal end form a knocking massage.

[0041] Here, the forward rotation and the reverse rotation of the rotating shaft 2 are relative concepts, for example, when the rotating shaft 2 rotates clockwise as the forward rotation direction, the rotating shaft 2 rotates counterclockwise as the reverse rotation direction; when the rotating shaft 2 rotates counterclockwise as the forward rotation direction, the rotating shaft 2 rotates clockwise as the reverse rotation direction.

[0042] Based on the above structural design, the driving mechanism 3 drives the rotation shaft 2 to rotate forward, and under the constraint of the retaining rod 6, the massage swing arm 4 can be forced to reciprocate along the rotation shaft 2, thereby realizing the kneading massage of the massage head 4a on the user's back. The driving mechanism 3 drives the rotation shaft 2 to rotate reversely, and under the action of the retaining rod 6, the massage swing arm 4 can be forced to swing eccentrically relative to the rotation shaft 2, thereby realizing the knocking massage of the massage head 4a on the user's back. By controlling the rotation of the rotation shaft 2, the kneading and knocking massage functions can be realized, that is, a set of driving mechanism is shared for the kneading and knocking functions, which can simplify the device, reduce the cost, has the advantages of simple and compact structure, and is helpful to the lightweight design of the seat.

[0043] Further, as shown in Figure 3 and 4 , two sets of sleeves 21 are rotatably sleeved on the rotation shaft 2, and the two sets of sleeves 21 are each provided with an annular groove 211, and the ends of the two massage swing arms 4 away from the massage head 4a are rotatably sleeved on the two annular grooves 211, respectively. The two side walls of the annular groove 211 are inclined relative to the center line of the rotation shaft 2, that is, an angle is formed between the center line of the annular groove 211 and the center line of the first rotation shaft B1, and the two sides of the end of the massage swing arm 4 close to the corresponding sleeve 21 are in sliding contact with the two side walls of the annular groove 211, respectively. The two sets of sleeves 21 are symmetrically arranged on the rotation shaft 2. The two sets of sleeves 21 are eccentrically sleeved on the rotation shaft 2 through a one-way bearing 22. In this embodiment, the direction of rotation of the rotation shaft 2 is the transmission direction of the one-way bearing 22. The positions of the two sets of sleeves 21 on the rotation shaft 2 are each provided with an eccentric cam 24 protruding radially outward, and the two sets of sleeves 21 are each sleeved on the two eccentric cams 24 through a one-way bearing 22.

[0044] Based on this, the working principle of the kneading massage is as follows: the driving mechanism 3 drives the rotation shaft 2 to rotate forward, the one-way bearing 22 can transmit to the sleeve 21 to make the sleeve 21 rotate, and the sleeve 21 can transmit to the massage swing arm 4. At this time, the inclined side wall of the annular groove 211 and the side wall of the massage swing arm 4 form a bevel cam transmission, and under the constraint of the retaining rod 6, the rotation of the rotation shaft 2 can force the massage swing arm 4 to reciprocate along the rotation shaft 2, that is, the massage swing arm 4 can swing left and right, thereby forming a reciprocating kneading massage of the massage head 4a on the user's back.

[0045] The working principle of the knocking massage is as follows: the driving mechanism 3 drives the rotating shaft 2 to rotate reversely, at this time, the one-way bearing 22 does not transmit power, the sleeve 21 cannot rotate with the rotating shaft 2, since the sleeve 21 is eccentrically sleeved on the rotating shaft 2 through the one-way bearing 22, that is, the center lines of the two one-way bearings 22 are eccentrically arranged relative to the center line of the rotating shaft 2. Therefore, the rotating shaft 2 reversely rotates, and under the eccentric transmission effect, the rotating motion of the rotating shaft 2 is converted into the back-and-forth swinging of the massage swing arm 4, so that the reciprocating knocking massage of the massage head 4a on the back of the user is realized.

[0046] By Figure 4 It can be seen that, in the embodiment, the eccentric directions of the two sets of sleeves 21 relative to the rotating shaft 2 are opposite, that is, the eccentric directions of the two eccentric cams 24 relative to the rotating shaft 2 are opposite. In this way, when the rotating shaft 2 reverses, the two eccentric cams 24 can drive the two sets of massage swing arms 4 to swing in different directions, so that the two massage heads 4a form reciprocating and alternating knocking massage on the back of the user, and the massage experience is improved.

[0047] As Figure 1 shown, in the embodiment, the retaining rod 6 is connected with the massage swing arm 4 through a spherical hinge, and is connected with the base 1 through rotation. In this way, when kneading massage is performed, the rotating shaft 2 rotates forward, and the massage swing arm 4 can swing left and right with the hinge point of the retaining rod 6 and the massage swing arm 4 as the fulcrum; when knocking massage is performed, the rotating shaft 2 reverses, and the massage swing arm 4 can swing back and forth with the hinge point of the retaining rod 6 and the massage swing arm 4 as the fulcrum, further improving the flexibility of the movement of the massage swing arm 4.

[0048] Please refer Figure 4 and 5 , for easy assembly, one end of the sleeve 21 is fixedly provided with a check ring 23, the surface of the sleeve 21 near the check ring 23 is provided with an outwardly protruding annular boss 2a, and the space surrounded by the inner side wall of the check ring 23 and the inner side wall of the annular boss 2a and the circumferential surface of the sleeve 21 constitutes an annular groove 211. In the embodiment, a C-shaped clamp spring is fixedly sleeved on the sleeve 21 outside the check ring 23. When the sleeve 21 rotates with the rotating shaft 2, the check ring 23 and the C-shaped clamp spring can ensure that the proximal end of the massage swing arm 4 is always in the corresponding annular groove 211. When the rotating shaft 2 reverses, the check ring 23 and the C-shaped clamp spring can ensure that the proximal end of the massage swing arm 4 and the annular groove 211 maintain a relatively fixed state.

[0049] As Figure 2 shown, the driving mechanism 3 includes a motor 31, the motor 31 can directly or indirectly drive the rotating shaft 2 to rotate, and the forward and reverse rotation of the motor 31 can directly or indirectly drive the rotating shaft 2 to rotate forward and reverse.

[0050] In the embodiment, the motor 31 can drive the rotating shaft 2 to rotate through the speed reduction assembly, and the specific process is as follows: the output component 32 is sleeved on the output shaft of the motor 31, the motor 31 drives the output component 32 to rotate, and the rotating shaft 2 can be driven to rotate through the transmission of the speed reduction assembly.

[0051] Further, referring to Figure 3 In the embodiment, the output component 32 is a worm, the speed reduction assembly comprises a transmission shaft 3a rotatably arranged above the output component 32, the transmission shaft 3a is provided with a transmission gear 33 and a first gear 34 at two ends along the axial direction of the transmission shaft 3a respectively, and the rotating shaft 2 is provided with a second gear 35, wherein the transmission gear 33 is engaged with the worm, and the first gear 34 is engaged with the second gear 35. The motor 31 drives the output component 32 to rotate, so as to drive the transmission gear 33 to rotate, and the first gear 34 on the transmission shaft 3a is driven to rotate, and the second gear 35 is driven to rotate. In this way, the stability of transmission is improved.

[0052] As shown in Figure 9 The massage swing arm 4 is made of metal material, and the heating element 5 is arranged at the distal end of the massage swing arm 4. Since the metal has good heat conduction performance, the heating element 5 can transmit heat to the massage head 4a in the form of heat conduction.

[0053] Specifically, as shown in Figures 10 to 13 The distal end of the massage swing arm 4 is provided with a boss structure 41 with an annular structure, and the massage head 4a is configured as a roller structure and is provided with an annular groove 4a1 on one side, which is sleeved on the boss structure 41, that is, the inner side wall of the annular groove 4a1 is in contact with the outer side wall of the boss structure 41. The heating element 5 generates heat, and the heat generated by the heating element 5 can be quickly conducted to the boss structure 41 through the massage swing arm 4. Since the massage head 4a is sleeved on the boss structure 41 through the annular groove 4a1, there is a large contact area between the two, so that the massage head 4a can be quickly heated in the form of heat conduction, and the user can have a warm and comfortable massage experience during massage, promote local blood circulation, and enhance the massage effect.

[0054] Please refer to Figure 10 and 12The heating element 5 comprises a heating sheet 51 fixed on the outer side of the distal end of the massage swing arm 4. The heating sheet 51 generates heat which can be transmitted to the boss structure 41 through the massage swing arm 4, and then transmitted to the massage head 4a by the boss structure 41. A temperature sensor 52 is fixed on the heating sheet 51. The temperature sensor 52 can detect the temperature change of the heating sheet 51, so as to ensure that the temperature of the heating sheet 51 and the massage head 4a is always maintained within an appropriate range, thereby bringing a safe, comfortable and stable massage experience to the user. In the embodiment, the heating sheet 51 has a heating layer which can generate heat by using a resistance wire or by using a graphene material. Both of the two heating methods have the advantages of good heating performance and good stability.

[0055] As shown in Figure 9 and 10 , a metal cover 42 is arranged on the massage swing arm 4 corresponding to the position of the heating element 5, and the metal cover 42 covers the outer side of the heating element 5. In the embodiment, the metal cover 42 and the massage swing arm 4 are both made of aluminum alloy material. The advantage of this design is that the metal cover 42 can protect the heating element 5, and at the same time, the metal cover 42 made of aluminum alloy also has good heat conductivity. In use, the metal cover 42 can cooperate with the heating element 5 to dissipate heat, and the heat can be transmitted to the corresponding area of the backrest in the form of heat radiation, so that the user can feel warm on the back, and the comfort of the massage is further improved.

[0056] In the embodiment, the upper end of the mounting plate 1a is rotatably connected to the backrest A. As shown in Figure 6 and 7 , a lifting mechanism B is arranged in the backrest A. The lifting mechanism B can drive the upper end of the mounting plate 1a to rotate around the backrest A, so that the lower part of the mounting plate 1a can move forward and backward relative to the backrest A. By rotatably connecting the upper end of the mounting plate 1a to the backrest A, and driving the upper end of the mounting plate 1a to rotate around the backrest A by the lifting mechanism B, the lower part of the mounting plate 1a moves forward and backward, which can change the forward and backward protruding state of the waist area of the seat, and realize the forward and backward adjustment of the waist support.

[0057] Further, as shown in Figures 6 to 8 , the lifting mechanism B is located at the rear side of the mounting plate 1a, and comprises an air bag B1 fixed in the backrest A, and the air bag B1 is connected to an air pump. When the waist support is not used, the air bag B1 is in an un-inflated state, and the air bag B1 abuts against the rear side of the mounting plate 1a. When the waist support function is needed to be used, the air pump inflates the air bag B1, and the air bag B1 expands, which can push the lower part of the mounting plate 1a forward.

[0058] Further, as shown in Figure 6 and 7As shown, the jacking mechanism B further comprises a mounting plate B2 arranged at the rear side of the mounting base plate 1a, the upper end of the mounting base plate 1a is rotatably connected to the upper end of the mounting plate B2, the lower end of the mounting base plate 1a is in a suspended state, and the air bag B1 is fixedly arranged on the mounting plate B2. When the air bag B1 is inflated, the upper end of the mounting base plate 1a is caused to rotate upward around the upper end of the mounting plate B2, and the lower end of the mounting base plate 1a is pushed forward relative to the backrest A. When the air bag B1 is deflated, the mounting base plate 1a can be rotated downward under the action of gravity, and the lower end of the mounting base plate 1a can be moved toward the mounting plate B2. Such a structure is simple and compact, so that the automobile seat can realize compact and lightweight design on the basis of having the functions of waist support and massage.

[0059] Referring to Figure 8 In order to improve the stroke of the front and rear adjustment of the waist support, the number of air bags B1 is at least two, and the adjacent two air bags B1 are arranged in an overlapping manner.
