Description

Technical Field

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

[0002] In order to improve passengers' fatigue caused by sitting for a long time and enhance driving comfort, massagers are usually installed on vehicle seats.

[0003] Regarding the seat massage function, the mainstream technology is to install air bags in the backrest of the car seat and achieve the purpose of massage by regularly inflating and deflating the air bags. In the existing technology, most seats integrate air bags in the backrest lumbar support area and the seat cushion, while ignoring the fatigue of the occupants' shoulders. Although a few manufacturers have installed massage air bags at the shoulder position of the seat, the overall strength of the air bag massage is small, and the overall comfort of the seat needs to be improved. Summary of the invention

[0004] In view of this, one of the purposes of the present invention is to provide a kneading massage device, which is intended to effectively relieve the shoulder fatigue of the occupant.

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

[0006] A kneading massage device comprises a shoulder rest for being arranged at the shoulder position of a seat back, characterized in that a massage component and a driving component for driving the massage component to move are arranged inside the shoulder rest, the massage component has a massage head, and when the massage head contacts the shoulder of an occupant, the driving component can drive the massage head to swing back and forth to simulate a kneading massage.

[0007] By adopting the above structure, the driving assembly drives the massage head to move in a reciprocating manner, which can simulate kneading massage of the occupant's shoulders, thereby effectively relieving the fatigue of the occupant's shoulders caused by long-term riding.

[0008] Preferably, the driving assembly includes a transmission shaft that can rotate in the shoulder rest, annular grooves are provided at both ends of the transmission shaft, the massage assembly includes a massage swing arm, one end of the massage swing arm is rotatably mounted on the annular groove, and the other end is connected to the massage head, both side walls of the annular groove are arranged obliquely relative to the center line of the transmission shaft, and both sides of the massage swing arm close to one end of the transmission shaft are in sliding contact with the side walls of the transmission shaft respectively; when the massage head is subjected to resistance from the mask or the user's shoulder, the transmission shaft rotates, and the massage swing arm can be forced to swing back and forth along the axis of the transmission shaft under the transmission action of the inclined side walls of the annular groove, so that the massage head at the far end swings back and forth. The above structure can realize kneading massage of the occupant's shoulders and relieve the occupant's shoulder fatigue.

[0009] Preferably, the drive assembly further comprises a motor disposed in the middle of the shoulder rest, the output end of the motor being connected to a worm extending in a vertical direction, the worm being meshedly connected to a worm wheel, and the worm wheel being fixedly sleeved on the transmission shaft. With the above structure, the transmission shaft can be provided with rotational power through the worm wheel transmission.

[0010] As a preferred embodiment, a positioning wheel is fixedly arranged inside the shoulder rest, and the transmission shaft is rotatably supported inside the positioning wheel. The above structure can ensure the stable rotation of the transmission shaft.

[0011] Preferably, eccentric wheels are fixedly arranged at both ends of the transmission shaft, the annular groove is provided on the eccentric wheel, the massage swing arm comprises an annular portion rotatably mounted in the annular groove and a rod-shaped portion arranged at the upper end of the annular portion, the extension direction of the rod-shaped portion is consistent with the inclination direction of the annular groove, and the massage head is fixedly arranged at the top front end position of the rod-shaped portion. With the above structure, when the massage head is subjected to resistance from the mask or the user's shoulder, the transmission shaft rotates, and the transmission action of the inclined side wall of the annular groove can force the annular portion and the rod-shaped portion to swing back and forth along the axial direction of the transmission shaft, so that the massage head at the far end swings back and forth.

[0012] Preferably, a retraction control mechanism is installed in the shoulder rest, which is used to switch the massage head between protruding from the shoulder rest surface and being stored inside the shoulder rest. The above structure can ensure that when the shoulder kneading massage assembly is not in use, the passenger's shoulder will not feel a foreign body when it rests against the shoulder rest.

[0013] As a preferred embodiment: the contraction control mechanism includes a slider and a driving member for controlling the slider to reciprocate in the shoulder rest, the slider has a groove, the annular portion is provided with a guide rod at one end away from the massage head, the guide rod is located in the groove, one side of the groove has a guide slope, when the slider moves to one side, it can drive the massage swing arm to swing forward under the transmission action of the guide slope and the guide rod; a first elastic element is connected between the massage swing arm and the shoulder rest, the first elastic element applies a pulling force to rotate backward to the massage swing arm. With the above structure, through the provided guide slope, the movement of the slider can drive the guide slope to move relative to the guide rod, thereby causing the massage swing arm to swing forward, and the provided first elastic element can also apply a backward pulling force to the massage swing arm in real time, so as to ensure that the shoulder rest kneading massage device is always in a folded state when not in use.

[0014] Preferably, a shoulder support frame is arranged inside the shoulder support, and the massage component and the drive component are both arranged on the shoulder support frame. With the above structure, the massage component and the drive component can be installed more stably.

[0015] A second object of the present invention is to provide a car seat.

[0016] A car seat includes a seat back, characterized in that the kneading massage device is integrated and installed at the shoulder position of the seat back. The above structure can make the car seat have a shoulder massage function, thereby effectively relieving the fatigue of the occupants' shoulders caused by long-term sitting.

[0017] As a preferred embodiment: the shoulder rest can be installed at the shoulder position of the seat back so as to be flipped forward and backward, a second elastic element is provided between the shoulder rest and the seat back, the second elastic element applies a thrust to flip the shoulder rest forward relative to the seat back, a driving mechanism is provided between the shoulder rest and the seat back, the driving mechanism is used to actively control the shoulder rest to overcome the resistance of the second elastic element and rotate and fold backward; when the shoulder rest is in the forward unfolded state, the thrust from the shoulder of the occupant can force the shoulder rest to overcome the resistance of the second elastic element and passively rotate and fold backward. The above structure can meet the needs of occupants of different body shapes for shoulder rests. When the car is hit, the thrust applied by the shoulder of the occupant to the shoulder rest can make the shoulder rest actively collapse in succession, thereby effectively reducing the impact force on the shoulder of the occupant, thereby ensuring the riding safety of the occupant.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The kneading massage device and the car seat provided by the present invention can simulate kneading the shoulders of the occupants by driving the massage head to move in a reciprocating swinging manner through the driving assembly, thereby effectively relieving the fatigue of the shoulders of the occupants.

[0020] 2. With the massage device provided by the present invention, the driving assembly drives the transmission shaft to rotate and transmits the transmission to the massage swing arm. Since the massage head at the far end of the massage swing arm will be subject to the resistance of the seat cover or the user's shoulder, and the inclined side wall of the annular groove and the side wall of the massage swing arm form an inclined cam transmission, the rotation of the transmission shaft can force the massage swing arm to swing back and forth along the axis of the transmission shaft, that is, the massage swing arm can swing left and right, so that the massage head at the far end forms a reciprocating swinging kneading massage on the user's back, which has the advantages of good massage effect and simple structure.

[0021] 3. The driving member drives the slider to move and the pulling force of the first elastic element can force the massage swing arm to rotate, thereby realizing the massage head to expand forward and fold backward. The overall operation is very simple. At the same time, by folding the massage head, it can also ensure that the shoulder rest kneading massage device will not make the occupant feel a foreign body when not in use.

[0037] The present invention is further described below in conjunction with embodiments and drawings.

[0038] Embodiment 1:

[0039] like Figures 1 to 3As shown, a kneading massage device includes a shoulder rest 1 installed at the shoulder position of a seat back 15, wherein a massage component A and a driving component B for driving the massage component A to move are arranged inside the shoulder rest 1, wherein the massage component A includes a massage head 3, and the massage head 3 is used to fit the shoulder of the occupant, and the driving component B is running to drive the massage head 3 to move in a reciprocating swinging manner.

[0040] With such a design, the massage assembly A drives the massage head 3 to swing back and forth, which can simulate the kneading action, thereby achieving kneading massage on the shoulders of the occupant and effectively alleviating the shoulder fatigue of the occupant.

[0041] like Figure 2 and Figure 3 As shown, in this embodiment, a shoulder rest frame 2 is integrated inside the shoulder rest 1, and the massage component A and the drive component B are both installed on the shoulder rest frame 2, so as to ensure that the kneading massage device has a more stable structure.

[0042] Specifically, Figures 3 to 5 As shown, the driving component B includes a transmission shaft 7 that can rotate in the shoulder support frame 2, and the transmission shaft 7 is arranged along the length direction of the shoulder support frame 2. An annular groove 10a is provided at both ends of the transmission shaft 7. The massage component A includes a massage swing arm 11. One end of the massage swing arm 11 is rotatably mounted on the annular groove 10a, and the other end is connected to the massage head 3. Both side walls of the annular groove 10a are arranged obliquely relative to the center line of the transmission shaft 7. In this embodiment, when the shoulder kneading installation device is not in use, the annular groove 10a is inclined toward the middle position of the lower end of the shoulder support frame 2, and the two sides of the massage swing arm 11 close to one end of the transmission shaft 7 are in sliding contact with both side walls of the transmission shaft 7 respectively. The rotation of the transmission shaft 7 can drive the annular groove 10a to rotate synchronously, and the movement trajectory of the annular groove 10a is in a wave shape that swings back and forth on the vertical plane. Since the massage head 3 is affected by the resistance of the shoulder support cover or the occupant's shoulder, under the transmission action of the inclined side wall of the annular groove 10a, the massage swing arm 11 is forced to reciprocate along the axial direction of the transmission shaft 7, so that the massage head 3 at the far end swings back and forth, thereby simulating kneading massage of the occupant's shoulders and relieving the occupant's shoulder fatigue.

[0043] Furthermore, the driving component B also includes a motor 4 fixedly installed in the middle position inside the shoulder rest frame 2, and the output end of the motor 4 is connected to a worm 5 extending in the vertical direction, and the worm 5 is meshingly connected to a worm wheel 6, which is fixedly mounted on a transmission shaft 7. Such a design converts the power transmission from longitudinal transmission to horizontal transmission, thereby greatly reducing the overall thickness of the shoulder rest 1.

[0044] In this embodiment, a positioning wheel 8 is fixedly installed inside the shoulder support frame 2 through a positioning sleeve 9. Two positioning wheels 8 are provided, and the two positioning wheels 8 are symmetrically distributed on the left and right sides of the worm wheel 6. The transmission shaft 7 is rotatably supported inside the positioning wheels 8. Such a design can ensure that the worm wheel 6 and the worm 5 can stably perform meshing transmission.

[0045] For example Figure 5 and Figure 6 As shown, eccentric wheels 10 are fixedly mounted at both ends of the transmission shaft 7, and an annular groove 10a is formed on the eccentric wheel 10. The massage swing arm 11 includes an annular portion 11a rotatably mounted in the annular groove 10a, and a rod-shaped portion 11b arranged at the upper end of the annular portion 11a, and the extension direction of the rod-shaped portion 11b is consistent with the inclination direction of the annular groove 10a. The massage head 3 is fixedly mounted at the top front end position of the rod-shaped portion 11b. Such a design can ensure that the massage head 3 is in a backward folded state when the massage component A is not in use.

[0046] like Figure 3 As shown, a retraction control mechanism C is also installed inside the shoulder rest 1, and the retraction control mechanism C is used to switch the massage head 3 between protruding from the surface of the shoulder rest 1 and folding inside the shoulder rest 1.

[0047] Specifically, Figures 7 to 11As shown, the contraction control mechanism C includes a slider 13 and a driving member 12 for controlling the slider 13 to reciprocate inside the shoulder support frame 2. In this embodiment, the driving member 12 can be a cylinder or a screw motor. A groove 13a is formed on the top of the slider 13. A guide rod 11c is formed on the end of the annular portion 11a away from the massage head 3. The guide rod 11c is located in the groove 13a. A guide slope 13b is provided on one side of the groove 13a. In this embodiment, the slider 13 is a long strip structure and is arranged parallel to the transmission shaft 7. The groove 13a is arranged at one end close to the annular groove 10a. The guide slope 13b extends toward the rear end of the outer side of the shoulder support frame 2. A mounting block 13c extending downward is formed on the slider 13. The output end of the driving member 12 is fixedly connected to the mounting block 13c. When the driving member 12 drives the slider 13 to move toward the middle position of the shoulder support frame 2, the transmission effect of the guide slope 13b and the guide rod 11c can make the massage swing arm 11 swing forward, thereby realizing the forward expansion of the massage component A. A hooking portion 11d extends outward from the side of the rod-shaped portion 11b, and a first elastic element 14 is connected between the hooking portion 11d and the rear end of the shoulder support frame 2. In this embodiment, the first elastic element 14 is a tension spring, which can continuously apply a backward pulling force to the massage swing arm 11. Such a design can ensure that the shoulder support kneading massage device can be stably folded when not in use, thereby avoiding giving the occupant a foreign body sensation and affecting the riding comfort. At the same time, when the shoulder support kneading massage device is finished using, the guide rod 11c can rely on the pulling force of the first elastic element 14 to rest against the groove 13a again, thereby completing the folding of the massage component A.

[0048] Combined with the above structure, the specific working principle of the kneading massage device is as follows:

[0049] When the kneading massage device is not in use, the massage swing arm 11 is in a backward folded state due to the pulling force of the first elastic element 14, and the guide rod 11c is located in the groove 13a. When the kneading massage device needs to be used, the driving member 12 drives the slider 13 to slide toward the middle position of the shoulder support frame 2. At this time, the transmission action of the guide inclined surface 13b and the guide rod 11c can make the massage swing arm 11 rotate forward as a whole, and make the massage head 3 close to the shoulder support cover. Then, the motor 4 runs, and the power is transmitted through the worm gear 6 and the worm 5, so that the transmission shaft 7 rotates. The massage head 3 is blocked by the seat cover and the shoulder of the occupant and cannot rotate forward synchronously. Under the transmission action of the inclined side wall of the annular groove 10a, the massage head can be driven to swing back and forth along the axial direction of the transmission shaft 7, thereby simulating the kneading massage of the occupant's shoulders, effectively reducing the fatigue of the occupant's shoulders. When the kneading massage device is finished being used, the driving member 12 drives the slider 13 to slide toward the side of the shoulder support frame 2. Under the pulling force applied by the first elastic element 14, the upper end of the massage swing arm 11 rotates backward, thereby folding the massage head 3, and the guide rod 11c is affected by the rotational force of the massage swing arm 11 and rests against the groove 13a again.

[0050] Embodiment 2:

[0051] like Fig.15 As shown, a car seat includes a seat back 15, and the kneading and massaging device described in Example 1 is integrated and installed at the shoulder position of the seat back 15.

[0052] like Figure 12 to Figure 14 As shown, the shoulder rest 1 can be installed at the shoulder position of the seat back 15 in a forward and backward flipping manner, a second elastic element 20 is installed between the shoulder rest 1 and the seat back 15, and the second elastic element 20 exerts a thrust to flip the shoulder rest 1 forward relative to the seat back 15. A driving mechanism is also installed between the shoulder rest 1 and the seat back 15, and the driving mechanism is used to actively control the shoulder rest 1 to overcome the resistance of the second elastic element 20 and rotate and fold backward. When the shoulder rest 1 is in the forward unfolded state, the thrust from the shoulder of the occupant can force the shoulder rest 1 to overcome the resistance of the second elastic element 20 and passively rotate and fold backward.

[0053] Specifically, the driving mechanism includes a driving motor 16 fixedly mounted on the rear end of the seat back 15, a screw rod 17 is installed at the output end of the driving motor 16, the screw rod 17 is arranged along the length direction of the seat back 15, a moving block 18 is threadedly assembled on the screw rod 17, the lower end of the shoulder rest 1 is rotatably mounted on the seat back 15 on both sides, and a swing arm 19 extending backward is fixedly mounted on the shoulder rest 1, a locking groove 19a is formed on the swing arm 19, the locking groove 19a is open upward, and the lower end of the moving block 18 abuts against the locking groove 19a, the second elastic element 20 is a pneumatic spring, and its two ends are rotatably mounted on the middle part of the swing arm 19 and the base of the driving motor 16 respectively.

[0054] Combination Fig.12 and Fig.13 When the car seat is not in use, the moving block 18 is at the bottom of the screw rod 17, and the second elastic element 20 is in a power storage state through the swing arm 19. When the driving motor 16 drives the moving block 18 to move upward along the screw rod 17, the second elastic element 20 can unload the force upward, thereby pushing the swing arm 19 to move upward, so that the shoulder rest 1 rotates forward to meet the needs of passengers of different body shapes for the shoulder rest 1. During the whole process, the locking groove 19a always abuts against the bottom of the end of the moving block 18. Combined with Fig.14 When the shoulder rest 1 is in the forward unfolded state, the thrust from the shoulder of the passenger can force the swing arm 19 to overcome the upward thrust of the second elastic element 20 and move downward, and the locking groove 19a moves downward and separates from the moving block 18, thereby causing the shoulder rest 1 to passively fold backward. With this design, when the car is hit, the shoulder rest 1 can collapse backward to reduce the impact force on the shoulder of the passenger, and the pneumatic spring 20 further reduces the impact force on the passenger, ensuring the safety of the passenger. During the entire collapse process, no force is applied to the moving block 18, thereby ensuring that the screw rod 17 will not be damaged and the service life of the entire drive mechanism is guaranteed.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present invention.
