Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of massage seats, in particular to a massage core, a massage seat and a vehicle. BACKGROUND

[0002] The seat massage comfort system adopts pneumatic massage or mechanical massage. The mechanical massage has greater force and more significant massage effect than the pneumatic massage. However, when an emergency occurs in a vehicle, if the mechanical massage core is still working, it may cause harm to the human body.

[0003] In related technologies, the mechanical massage core adopts a multi-link mode to realize the ejection and retraction of the mechanical arm. In an emergency, the mechanical arm needs to be retracted by driving the link through an energy storage member, or the mechanical arm is allowed to rotate freely and retract under external force by allowing part of the link to explode and break. The energy storage member is usually a spring. After repeated compression and release, the spring will have performance degradation, making it difficult to retract the mechanical arm. The link breakage results in high maintenance cost of the massage core. SUMMARY

[0004] Embodiments of the present application aim to provide a massage core, a massage seat and a vehicle to at least solve the problem that the mechanical arm of the massage core is difficult to retract after performance degradation of the energy storage member, and solve the problem that the maintenance cost is high after the mechanical arm is retracted in an emergency by breaking the link of the massage core.

[0030] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0031] In the first aspect, referring to Figure 1 , the embodiments of the present application provide a massage core 100, which includes a base 1, a sliding seat 2, a mechanical arm assembly 3 and a lifting assembly 4. The sliding seat 2 is slidably arranged on the base 1; the mechanical arm assembly 3 is arranged on the base 1, and is used to apply kneading massage and / or knocking massage to a user; the lifting assembly 4 is arranged on the sliding seat 2, and is in transmission connection with the mechanical arm assembly 3 and the base 1. The lifting assembly 4 is used to apply a force to the base 1 to drive the sliding seat 2 to move relative to the base 1, and is used to drive the mechanical arm assembly 3 to switch between an extended state and a retracted state. Illustratively, referring to Figures 2 to 4 , the massage core 100 further includes a connecting rod 9, one end of which is hinged to the sliding seat 2 and the other end of which is hinged to the mechanical arm assembly 3; the mechanical arm assembly 3 includes a first arm 31, a first end of the first arm 31 being provided with a massage structure, and a second end of the first arm 31 being hinged to the base 1; when the sliding seat 2 moves along the base 1, the connecting rod 9 applies a force to the middle part of the first arm 31 and drives the first arm 31 to rotate, for example, the other end of the connecting rod 9 is hinged to the middle part of the first arm 31, so that the first end of the first arm 31 is close to or away from the base 1. That is, the lifting assembly 4 drives the mechanical arm assembly 3 to switch between the extended state and the retracted state through the connecting rod 9. When the first arm 31 rotates and the first end is away from the base 1, the mechanical arm assembly 3 changes to the extended state; when the first arm 31 rotates and the first end is close to the base 1, the mechanical arm assembly 3 changes to the retracted state. Optionally, the base 1 is in the shape of a flat plate or a rectangular frame, and when the mechanical arm assembly 3 is in the retracted state, the massage core 100 as a whole is in the shape of a flat plate, which is convenient to install in the back of a seat.

[0032] For the specific structure of the first arm 31, illustratively, please refer toFigure 2 The first end of the first arm 31 extends towards the first direction X and can simultaneously extend towards a direction away from the base 1. The second end of the first arm 31 extends towards the base 1. The rotation axis of the first arm 31 is substantially parallel to the base 1, and the first direction X is parallel to the base 1. When the connecting rod 9 applies a force to the middle of the first arm 31, and the force has a component towards the first direction X, the first arm 31 rotates clockwise (see Figure 2 ), so that the first end of the first arm 31 moves towards the base 1, i.e. the mechanical arm assembly 3 is transformed to the retracted state. When the connecting rod 9 applies a force to the second end of the first arm 31, and the force has a component away from the first direction X, the first arm 31 rotates counterclockwise (see Figure 2 ), so that the first end of the first arm 31 moves towards a direction away from the base 1, i.e. the mechanical arm assembly 3 is transformed to the ejecting state. In the embodiment, the first direction X is only used to illustrate the structure of the first arm 31, and is not used to limit the sliding direction of the sliding base 2 relative to the base 1.

[0033] In some embodiments, please refer to Figures 2 to 4 The massage structure includes a second arm 32, the middle of the second arm 32 is rotatably connected to the first end of the first arm 31, and the two ends of the second arm 32 have massage heads. Exemplarily, the two ends of the second arm 32 are provided with rollers 321. The sliding friction between the second arm 32 and the covering layer on the seat during massage is reduced. In other embodiments, the massage structure includes rollers 321 provided on the first end of the first arm 31.

[0034] In some embodiments, the massage machine core 100 includes a plurality of mechanical arm assemblies 3. For example, please refer to Figure 3 and Figure 4 The massage machine core 100 includes two mechanical arm assemblies 3, which enhances the massage effect of the massage machine core 100.

[0035] In some embodiments, please refer to Figure 3 and Figure 4, the massage core 100 comprises a collapse assembly 5, the collapse assembly 5 comprises a locking piece 51, a collapse driver 52 and a connecting piece 53, the collapse driver 52 drives the locking piece 51 to normally lock the connecting piece 53 to the base 1, and the collapse driver 52 is used to drive the locking piece 51 to unlock the connecting piece 53 when receiving a collapse signal; the lifting assembly 4 is in transmission connection with the connecting piece 53, and the lifting assembly 4 is used to apply a force to the connecting piece 53 to drive the sliding seat 2 to move relative to the base 1. When the connecting piece 53 is normally locked to the base 1, the lifting assembly 4 can drive the sliding seat 2 to move along the base 1, and in turn drive the mechanical arm assembly 3 to switch between the ejection state and the retracted state; when the connecting piece 53 is unlocked, the transmission connection between the lifting assembly 4 and the base 1 is disconnected, so that the sliding seat 2 can slide freely along the base 1; and in turn the mechanical arm assembly 3 can be converted into the retracted state under the action of an external force, so as to reduce the harm to the human body when the vehicle is in an emergency.

[0036] In the related art, the mechanical arm assembly 3 needs to be retracted by an energy storage member, and the energy storage member is usually a spring. After repeated compression and release, the spring will have performance degradation, which makes it difficult to retract the mechanical arm assembly 3. Or the free state of the mechanical arm assembly 3 is achieved by breaking the connecting rod, which leads to high maintenance cost of the massage core 100. In the embodiments of the present application, the mechanical arm assembly 3 is converted into the retracted state by relying on an external force, without the need to set an energy storage member, which simplifies the structure of the massage core 100 and reduces the manufacturing cost. The problem that the mechanical arm assembly 3 of the massage core 100 is difficult to retract after the performance degradation of the energy storage member is improved. The mechanical arm assembly 3 does not need to break the connecting rod, which reduces the maintenance cost of the mechanical arm assembly 3 of the massage core 100 after emergency retraction.

[0037] In some embodiments, the sliding seat 2 is slidably arranged on the base 1 along the first direction X. For example, referring to Figure 3 and Figure 4 , the base 1 is provided with a sliding rail 11, and the sliding seat 2 is provided with a sliding block 21, the sliding block 21 is in sliding connection with the sliding rail 11, and the sliding rail 11 extends along the first direction X. Thus, the sliding seat 2 is slidably arranged on the base 1 along the first direction X. Optionally, the number of sliding rails 11 is multiple, which enhances the stability of the sliding connection between the sliding seat 2 and the base 1, for example, the number of sliding rails 11 is two. Optionally, the sliding seat 2 is in sliding connection with the same sliding rail 11 through multiple sliding blocks 21, which enhances the stability of the sliding connection between the sliding seat 2 and the base 1, for example, one sliding rail 11 is in sliding connection with two sliding blocks 21.

[0038] In some other examples, the sliding base 2 is slidably arranged along a curve on the base 1, and / or the driving direction of the first arm 31 by the lifting assembly 4 has an angle with the first direction X, and / or the sliding base 2 is rotatably arranged on the base 1 around an axis away from itself (i.e. the sliding base 2 is swingably arranged on the base 1). As long as the mechanical arm assembly 3 can be driven to change to the extended state or the retracted state when the first arm 31 is subjected to the force by the lifting assembly 4.

[0039] In some examples, referring to Figure 5 and Figure 6 , the collapsing assembly 5 comprises a collapsing mount 54, the collapsing mount 54 is provided with a mounting hole 541 extending along the first direction X, the connecting member 53 is slidably arranged in the mounting hole 541 along the first direction X; the connecting member 53 is provided with a locking slot 531 on one side along the second direction Y, the second direction Y is perpendicular to the first direction X; the locking member 51 is slidably arranged in the collapsing mount 54, the collapsing driver 52 is arranged in the collapsing mount 54, the collapsing driver 52 is used to drive the locking member 51 to move at least partially into the locking slot 531 or away from the locking slot 531, so as to lock or unlock the connecting member 53 in the collapsing mount 54. When the locking member 51 is at least partially in the locking slot 531, the locking member 51 will abut against the inner wall of the locking slot 531, preventing the connecting member 53 from sliding relative to the collapsing mount 54 along the first direction X, or sliding within a smaller range (without affecting the switching of the mechanical arm assembly 3 between the extended state and the retracted state by the lifting assembly 4); when the locking member 51 is away from the locking slot 531, the connecting member 53 can slide freely relative to the collapsing mount 54 along the first direction X, so that the sliding base 2 can slide freely relative to the base 1 along the first direction X. Optionally, the locking member 51 is in the shape of a rectangular sheet, and the locking slot 531 is a square slot. Optionally, the locking slot 531 is adapted to the locking member 51, for example, along the first direction X, the width of the locking slot 531 is equal to the thickness of the locking member 51 (in fact, the width of the locking slot 531 is slightly wider than the thickness of the locking member 51, for example, 1mm, 2mm or 3mm, etc.).

[0040] The collapsing driver 52 can drive the locking member 51 to rotate and / or translate. For example, the collapsing driver 52 is a rudder, the output end of the collapsing driver 52 is provided with an eccentric shaft, and the locking member 51 is connected to the eccentric shaft. Since the locking member 51 is arranged on the eccentric shaft, when the output shaft of the collapsing driver 52 rotates, the locking member 51 has a translation along a direction perpendicular to the output end, driving the locking member 51 to move at least partially into the locking slot 531 or away from the locking slot 531, and then locking or unlocking the connecting member 53 by driving the locking member 51 to rotate. In some other examples, referring to Figure 5 and Figure 6The collapsing mount 54 is provided with a sliding groove 542 extending along the second direction Y, and the locking member 51 is slidingly connected to the collapsing mount 54 through the sliding groove 542. The collapsing driver 52 is configured to drive the locking member 51 to move relative to the collapsing mount 54 along the second direction Y, so as to move the locking member 51 to be at least partially located in the locking groove 531 or away from the locking groove 531. The collapsing driver 52 can be a linear driver, which directly drives the sliding movement of the locking member 51 relative to the collapsing mount 54. Alternatively, referring to Figure 5 and Figure 6 The collapsing driver 52 is a rotary driver, for example, an electric motor. The output shaft of the collapsing driver 52 is provided with an eccentric wheel 521. The locking member 51 is provided with a through hole 511 extending through the locking member 51 along the first direction X and extending along a direction perpendicular to the first direction X and the second direction Y. Along the second direction Y, the opposite sides of the eccentric wheel 521 abut against the inner walls of the locking groove 531. When the collapsing driver 52 drives the eccentric wheel 521 to rotate, the locking member 51 is driven to slide relative to the collapsing mount 54 along the second direction Y.

[0041] After being used once, the collapsing assembly 5 can be simply reset, and the locking member 51 is driven by the collapsing driver 52 to re-lock the connecting member 53, so as to be used again. The reusability is high. It can be understood that when the connecting member 53 is re-locked, the sliding base 2 can be driven to slide along the base 1 by an external force, and the connecting member 53 is moved to the initial depth in the mounting hole 541 (i.e. the depth of the connecting member 53 in the mounting hole 541 when the locking member 51 locks the connecting member 53). Alternatively, the connecting member 53 is moved to the initial depth in the mounting hole 541 by the lifting assembly 4 performing the action of driving the mechanical arm assembly 3 to change to the collapsed state. In the above embodiment, the connecting member 53 can not be completely separated from the mounting hole 541 after the collapsing assembly 5 is used, so as to improve the problem that the connecting member 53 is difficult to be re-inserted into the mounting hole 541. In the embodiment in which the lifting assembly 4 includes the lead screw 41 and the first driving member 42, the connecting member 53 is not completely separated from the mounting hole 541, so that the lead screw 41 can still drive the connecting member 53 to translate relative to the lead screw 41 when the lead screw 41 rotates, instead of the connecting member 53 and the lead screw 41 rotating synchronously.

[0042] For the above lifting assembly 4, in some embodiments, referring to Figure 3 and Figure 4, the lifting assembly 4 comprises a screw rod 41 and a first driving member 42; the screw rod 41 is rotatably arranged on the sliding base 2, the screw rod 41 extends along the first direction X, and the screw rod 41 is threadedly connected with the connecting member 53; the first driving member 42 is arranged on the sliding base 2, the first driving member 42 is in transmission connection with the screw rod 41, and the first driving member 42 is configured to drive the screw rod 41 to rotate so as to drive the sliding base 2 to move relative to the base 1 along the first direction X. For example, the screw rod 41 is mounted on the sliding base 2 through a bearing, the rotation axis of the screw rod 41 is parallel to the first direction X, the connecting member 53 is provided with a threaded hole 532, the screw rod 41 is arranged in the threaded hole 532 and threadedly matched with the connecting member 53; the screw rod 41 is in transmission connection with the first driving member 42, so that the first driving member 42 drives the screw rod 41 to rotate to drive the sliding base 2 to move relative to the base 1 along the first direction X; the connecting rod 9 and the first arm 31 and the sliding base 2 can be rotatably connected through a bearing structure or rotatably connected through a ball head structure. When the connecting member 53 is locked by the locking member 51, the first driving member 42 drives the screw rod 41 to rotate to drive the sliding base 2 to move relative to the base along the first direction X, so that the connecting rod 9 applies a force to the first arm 31, and the force has a component parallel to the first direction X, thereby driving the first arm 31 to rotate counterclockwise or clockwise (see Figure 2 ). When the locking member 51 releases the locking of the connecting member 53, the sliding base 2 can freely slide along the base 1. The sliding base 2 is driven to move by the screw rod 41, and the sliding base 2 has a locking effect, that is, after the first driving member 42 is powered off, the sliding base 2 is maintained at the current position, and the first driving member 42 is not required to maintain the position of the sliding base 2, thereby reducing the energy consumption of the first driving member 42. Optionally, the first driving member 42 is a motor. Optionally, the first driving member 42 and the screw rod 41 are in transmission connection through a speed reduction mechanism, for example, in transmission connection through a belt structure, and the diameter of the belt pulley on the first driving member 42 is smaller than the diameter of the belt pulley on the screw rod 41.

[0043] It can be understood that the rotation axis of the connecting rod 9 relative to the sliding base 2, the rotation axis of the connecting rod 9 relative to the first arm 31, and the rotation axis of the first arm 31 relative to the base 1 are all substantially parallel to the base 1 and perpendicular to the first direction X. Optionally, the connecting rod 9 is hinged or ball-jointed with the sliding base 2, and the connecting rod 9 is hinged or ball-jointed with the first arm 31. The first arm 31 is hinged with the base 1 to ensure that the first arm 31 can rotate relative to the base 1 under the driving of the connecting rod 9.

[0044] In some embodiments, please refer to Figures 2 to 4 The massage core 100 further comprises a knocking assembly 6, the knocking assembly 6 is configured to drive the mechanical arm assembly 3 to repeatedly move in the direction away from and close to the base 1, thereby realizing knocking massage. For example, please refer to Figure 7The knocking assembly 6 comprises a knocking shaft 61, a shaft sleeve 62 and a second driving member 63. The knocking shaft 61 is movably arranged in the sliding base 2, and both ends of the knocking shaft 61 are provided with eccentric segments 611. The shaft sleeve 62 is sleeved on the eccentric segments 611, and the shaft sleeve 62 is connected with one end of the connecting rod 9. The second driving member 63 is arranged in the sliding base 2, and the second driving member 63 is used to drive the knocking shaft 61 to rotate relative to the sliding base 2. The axis of the eccentric segment 611 is spaced from the axis of the other part of the knocking shaft 61. When the second driving member 63 drives the knocking shaft 61 to rotate, the axis of the eccentric segment 611 rotates around the rotation axis of the knocking shaft 61. The shaft sleeve 62 is sleeved on the eccentric segment 611 and connected with the connecting rod 9, so as to drive the first end of the first arm 31 to repeatedly move in the direction away from and close to the base 1, and realize the knocking massage. Optionally, the shaft sleeve 62 is provided with a bearing, and the bearing is connected with the eccentric segment 611 in rotation. Optionally, the second driving member 63 is a motor. Optionally, the second driving member 63 and the knocking shaft 61 are connected through a speed reducer, for example, connected through a belt structure, and the diameter of the belt pulley on the second driving member 63 is smaller than the diameter of the belt pulley on the knocking shaft 61.

[0045] It can be understood that the rotation axis of the connecting rod 9 relative to the knocking shaft 61, the rotation axis of the connecting rod 9 relative to the first arm 31, and the rotation axis of the first arm 31 relative to the base 1 are all substantially parallel to the base 1 and perpendicular to the first direction X. Therefore, the rotation axis of the knocking shaft 61 is substantially parallel to the base 1 and perpendicular to the first direction X.

[0046] In some embodiments, the knocking shaft 61 is provided with a plurality of eccentric segments 611, and a plurality of shaft sleeves 62 are respectively sleeved on the plurality of eccentric segments 611. The plurality of shaft sleeves 62 are connected with the connecting rods 9 of the plurality of mechanical arm assemblies 3. The plurality of mechanical arm assemblies 3 are driven to realize the knocking massage. Optionally, the knocking shaft 61 is provided with two eccentric segments 611, and the two eccentric segments 611 are located at both ends of the knocking shaft 61, which is convenient for connecting with the shaft sleeve 62.

[0047] The axes of the plurality of eccentric segments 611 can not coincide, for example, the axes of the two eccentric segments 611 are located on opposite sides of the rotation axis of the knocking shaft 61, so that the knocking actions of the two first arms 31 corresponding to the two eccentric segments 611 are opposite, thereby enhancing the knocking massage effect. The axes of the plurality of eccentric segments 611 can be arranged at equal angles around the rotation axis of the knocking shaft 61, for example, the angle interval is 180 degrees, 120 degrees, 90 degrees, 60 degrees, etc.

[0048] In some embodiments, referring to Figure 3 and Figure 4 The massage core 100 further comprises a kneading assembly 7, which is used to drive the mechanical arm assembly 3 to move in the direction parallel to the base 1, so as to realize the kneading massage. Exemplarily, referring to Figure 8The kneading assembly 7 comprises a kneading shaft 71 and a third driving member 72. The kneading shaft 71 is rotatably arranged on the base 1. The kneading shaft 71 comprises two inclined segments 711 at two ends thereof. The axis of the inclined segment 711 is arranged at an angle with the rotation axis of the kneading shaft 71. The second end of the first arm 31 is rotatably connected to the inclined segment 711. The third driving member 72 is arranged on the base 1. The third driving member 72 is configured to drive the kneading shaft 71 to rotate relative to the base 1. When the third driving member 72 drives the kneading shaft 71 to rotate, the axis of the inclined segment 711 swings around the rotation axis of the kneading shaft 71. The second end of the first arm 31 is rotatably connected to the inclined segment 711, thereby driving the first arm 31 to swing around the rotation axis of the kneading shaft 71, and realizing kneading massage. Optionally, the first arm 31 is rotatably connected to the inclined segment 711 through a bearing. Optionally, the third driving member 72 is an electric motor. Optionally, the third driving member 72 is drivingly connected to the kneading shaft 71 through a speed reducer, for example, through a belt structure. The diameter of the pulley on the third driving member 72 is smaller than the diameter of the pulley on the kneading shaft 71.

[0049] In some embodiments, referring to Figure 4 The third driving member 72 is arranged on the collapsing mounting seat 54. The kneading shaft 71 is rotatably arranged on the collapsing mounting seat 54.

[0050] It can be understood that, since the first arm 31 swings around the rotation axis of the kneading shaft 71, the connecting rod 9 is ball-connected to the sliding seat 2 and the first arm 31. Since the connecting rod 9 is rotatably connected to the knocking shaft 61 through the shaft sleeve 62, the connecting rod 9 and the shaft sleeve 62 can be hingedly connected.

[0051] In some embodiments, the kneading shaft 71 is provided with a plurality of inclined segments 711. The first arms 31 of the plurality of mechanical arm assemblies 3 are rotatably connected to the plurality of inclined segments 711, respectively. The plurality of mechanical arm assemblies 3 are driven to realize kneading massage. Optionally, the kneading shaft 71 is provided with two inclined segments 711 at two ends thereof, which are convenient to be rotatably connected to the first arms 31.

[0052] The axes of the plurality of inclined segments 711 are mirror-symmetric along the length direction of the kneading shaft 71. For example, the axes of the two inclined segments 711 are located on the same side of the rotation axis of the kneading shaft 71 and in the same plane, so that the kneading actions of the two corresponding first arms 31 are mirror-symmetric, thereby enhancing the kneading massage effect. The axes of the plurality of inclined segments 711 can be arranged at equal angles around the rotation axis of the kneading shaft 71, for example, at angles of 180 degrees, 120 degrees, 90 degrees, 60 degrees, etc.

[0053] In the embodiments of the present application, the base 1 is flat, the sliding seat 2 is installed on the base 1, and the mechanical arm assembly 3, the lifting assembly 4, the knocking assembly 6 and the kneading assembly 7 are distributed and installed on the base 1 and the sliding seat 2, so that the whole massage mechanism is more compact in structure and smaller in size, and in particular, the whole massage mechanism is flat, which is convenient for installation on the backrest of the seat.

[0054] In some embodiments, referring to Figure 8 , the kneading assembly 7 further comprises a worm 73 and a worm wheel 74, the worm wheel 74 is sleeved on the kneading shaft 71, the worm 73 is rotatably arranged on the base 1, the worm 73 is engaged with the worm wheel 74, and the third driving member 72 is used to drive the worm 73 to rotate relative to the base 1. By rotating the worm wheel 74 driven by the worm 73, the torque output by the kneading shaft 71 is increased, and the problem that the kneading shaft 71 cannot rotate due to large resistance is improved. Moreover, when the third driving member 72 is powered off, the worm 73 locks the worm wheel 74, so that the kneading shaft 71 cannot rotate, and the swing position of the first arm 31 is locked.

[0055] In some embodiments, referring to Figure 9 , the massage mechanism further comprises a walking assembly 8, and the walking assembly 8 is used to drive the massage mechanism to move. For example, when the massage mechanism is installed on the seat, the massage mechanism can be driven to move relative to the seat to adjust the massage area of the human body. Exemplarily, the walking assembly 8 comprises a walking shaft 81, a first wheel 82, a second wheel 83 and a fourth driving member 84, the walking shaft 81 is rotatably arranged on the base 1, the first wheel 82 is arranged on the walking shaft 81, the second wheel 83 is rotatably arranged on the base 1, and the fourth driving member 84 is in transmission connection with the walking wheel. When the fourth driving member 84 rotates the walking shaft 81, the first wheel 82 rotates relative to the base 1, and if the first wheel 82 is in rolling contact with the seat, the massage mechanism can be driven to move relative to the seat, and at the same time, the second wheel 83 is passively rotated. Optionally, the fourth driving member 84 is a motor. Optionally, the fourth driving member 84 and the walking shaft 81 are in transmission connection through a speed reducer, for example, in transmission connection through a helical gear structure, and the diameter of the helical gear on the fourth driving member 84 is smaller than the diameter of the helical gear on the walking shaft 81. Optionally, the first wheel 82 is provided with a gear, the seat is provided with a rack, and the gear is engaged with the rack, which improves the problem of slipping when the walking assembly 8 drives the massage mechanism to move and enhances the reliability of the walking assembly 8 in driving the massage mechanism to move. It can be understood that the rotation axis of the second wheel 83 is parallel to the rotation axis of the walking shaft 81 or forms an acute angle.
