Description

Technical Field

[0001] The invention belongs to the technical field of automobile seats, and in particular relates to a lifting massage head and a waist massage device with the massage head. Background Art

[0002] With the continuous development of automobile technology, the functions of car seats are gradually extending and are no longer limited to providing a good driving and riding posture.

[0003] During long-distance driving, the waist of the driver and passengers is prone to fatigue due to long-term sitting. If a massager that can massage and knead the waist is integrated on the seat back to relieve the fatigue caused by long-term sitting, the main technical obstacles for R&D personnel are: 1. The design space of the seat back is limited, which is not conducive to the structural layout of the massager; 2. During the driving of the car, the massage head of the massager is always supported on the waist position of the driver and passenger, which will increase the risk of waist injury in the event of a car collision, resulting in reduced seat safety. Summary of the invention

[0004] In view of this, the present invention provides a lifting massage head with an ingenious structural design, which breaks through the technical barrier of integrating a massager on a backrest, avoids the massage head from always contacting the waist of the driver and passenger, and can ensure the safety of the seat.

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

[0006] A lifting massage head, the key of which is: comprising a mounting seat, a rotating wheel is rotatably mounted in the mounting seat, a screw is rotatably mounted in the middle of the rotating wheel in a threaded connection manner, when the screw rotates relative to the rotating wheel, it can move along the axial direction of the rotating wheel, the upper end of the screw passes through the mounting seat and is installed with a massage component, and a spring is arranged between the massage component and the mounting seat;

[0007] One end of the spring is fixedly connected to the mounting seat or the massage component in an alternative manner, and the other end is frictionally abutted against the corresponding mounting seat or the massage component.

[0008] With the above structure, after the lifting massage head is applied to the seat back, in the initial state, the spring is in a highly compressed state, and there is a minimum distance between the massage component and the mounting seat. At this time, the massage component is far away from the waist position of the driver and passenger, and no contact occurs, which can ensure that the safety of the seat is not affected by the massager. When the user uses the massage function, the drive component drives the rotating wheel to rotate. Since the spring is supported between the massage component and the mounting seat, the rotation of the rotating wheel will drive the screw to do a lifting movement, so that the massage component rises to the waist position of the driver and passenger. After the massage component rises to the waist position, the screw no longer rises further, but rotates synchronously with the rotating wheel. At this time, the massage component begins to rotate, thereby massaging the user's waist. The reverse movement of the drive component can make the massage component leave the waist position of the driver and passenger.

[0009] As a preferred embodiment, a friction plate is fixedly arranged on the lower side of the massage component, and the spring is a conical spring, whose large diameter end is fixed on the mounting seat, and the small diameter end is frictionally contacted on the friction plate. With the above structure, when the massage component moves up and down, the large diameter end is fixed to prevent the spring from rotating, and the small diameter end is frictionally contacted on the friction plate, which can ensure that the massage component rotates relative to the spring when the massage component rotates.

[0010] Preferably, a countersunk hole is provided at the lower end of the rotating wheel, and a limit plate is fixedly installed at the lower end of the screw, and the diameter of the limit plate is smaller than the inner diameter of the countersunk hole. With the above structure, when the screw rises to the highest position, the limit plate abuts against the countersunk hole, which can ensure that the screw does not rise further, thereby driving the massage component to rotate.

[0011] As a preference: the rotating wheel is a helical gear or a worm gear, with a rotating boss on its upper end, the mounting seat is provided with a mounting hole at a position corresponding to the rotating boss, and a ring boss at a position corresponding to the countersunk hole; a driving wheel mounting groove is provided in the mounting seat at a position corresponding to one side of the rotating wheel. With the above structure, assembly is easier to achieve, and the rotating wheel can be driven to rotate by placing a helical gear or a worm in the driving wheel mounting groove.

[0012] Preferably, the massage assembly includes a support plate, and a first massage head and a second massage head are installed on the upper side of the support plate, wherein the first massage head is fixedly connected to the support plate, and the second massage head is rotatably connected to the support plate. With the above structure, when the driver and passengers are given a waist massage, the massage assembly rotates synchronously with the screw, and then the first massage head that can only revolve and the second massage head that can both revolve and rotate can massage and knead the waist, which can fully relieve the fatigue of the driver and passengers' waist caused by long-term sitting, and has a high-end feel.

[0013] As a preferred embodiment, the middle of the support plate has a protrusion extending upward, the protrusion is a hollow structure with an open lower end, and locking notches are provided on both sides of the protrusion. The upper end of the screw rod extends into the protrusion, and a locking pin is radially inserted into the upper end of the screw rod, and both ends of the locking pin are respectively located in the locking notches. The above structure is adopted to facilitate the fixed assembly of the support plate and the upper end of the screw rod, making the assembly of the product easy to achieve.

[0014] Preferably, the support plate is provided with a fixing seat and a transfer seat at positions on both sides of the protrusion, the first massage head is fixedly mounted on the fixing seat, and the second massage head is rotatably connected to the transfer seat, wherein a positioning hole is provided in the middle of the transfer seat, and an inner positioning column adapted to the positioning hole is provided on the second massage head. The above structure can ensure the stability of the rotation of the second massage head, thereby improving the comfort of massage.

[0015] As a preferred embodiment, the outer ends of the first massage head and the second massage head are both cambered structures, and the upper end of the first massage head is higher than the upper end of the second massage head. The above structure can ensure the comfort of massage.

[0016] The present invention also provides a waist massage device, the key of which is that it includes a support assembly, on which a driving component and two groups of the above-mentioned lifting massage heads are installed, the driving component includes a motor and a rotating shaft driven to rotate by the motor, and the rotating shaft is rotatably installed on the mounting seats of the two groups of lifting massage heads to drive the rotating wheel to rotate.

[0017] With the above structure, two sets of lifting massage heads are driven by a rotating shaft, which is conducive to realizing the thin design of the massage mechanism and making it easier to integrate the massage mechanism on the seat back. After the massage mechanism is integrated on the seat back, the two sets of lifting massage heads can massage, knead, and push the two sides of the user's waist respectively, which can fully relieve the fatigue of the driver's waist caused by long-term sitting, and give the seat a waist massage function.

[0018] Preferably, the support assembly includes a panel and a rear cover that are snap-fitted together, the rear cover is provided with a sink that is adapted to the mounting seat, and the panel is provided with an assembly hole that is adapted to the massage component. With the above structure, the lifting massage head can be arranged as a whole in the support assembly. When the massage function is not used, the first massage head and the second massage head at the outermost end are completely located below the panel assembly hole, which can ensure the safety of riding. At the same time, the panel can also provide support for the non-massage area of ​​the back, which is conducive to improving the comfort of the seat.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. After the massage mechanism is integrated into the seat back, when the massage function is not in use, the massage head is stored in the support assembly, which prevents the massage head from always contacting the waist of the driver and passenger, which is beneficial to ensure the safety of the seat.

[0021] 2. The lifting structure of the massage head is cleverly designed. When using the massage function, the motor first drives the massage component to rise to the waist position of the driver and passenger, and then drives the massage component to rotate synchronously, so as to massage, knead and push the waist of the driver and passenger, so as to promote blood circulation and relieve muscle fatigue.

[0022] 3. The two sets of lifting massage heads are driven by a rotating shaft, and the motor is also arranged at the outer end, breaking through the technical barrier of limited backrest design space and realizing a thin structural design, so that the massage mechanism can be integrated and assembled on the seat back, giving the seat a lumbar massage function.

[0023] 4. The product structure is reasonably designed, and production, manufacturing and assembly are easy to achieve. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention is further described below in conjunction with embodiments and drawings.

[0032] like Figures 4 to 6As shown, a waist massage device, the main components involved are: a support assembly 8, a drive assembly 7 and two sets of lifting massage heads. Among them, the support assembly 8 includes a panel 8a and a rear cover 8b that are installed in a snap-fit ​​manner. The panel 8a can provide support for the non-massage area of ​​the back of the driver and passenger, which is conducive to improving the comfort of the seat; the rear cover 8b is provided with two sets of sink grooves 8b1, and the panel 8a is provided with two sets of assembly holes 8a1 that are directly opposite to the two sets of sink grooves 8b1. The two sets of lifting massage heads are respectively installed on the two sets of sink grooves 8b1. When the massage function is not used, the lifting massage heads are completely located below the assembly holes 8a1 of the panel 8a, which can ensure the safety of riding.

[0033] The driving assembly 7 includes a motor 7a, a reducer 7d and a rotating shaft 7b which are connected in sequence. In order to realize a thin structural design of the lumbar massage device so as to facilitate its installation in a seat back 9 with limited design space, in this embodiment, the rotating shaft 7b is arranged on the same side of the two groups of lifting massage heads and can drive the two groups of lifting massage heads to work simultaneously.

[0034] like Figures 1 to 3 As shown, the specific structure of the lifting massage head is as follows:

[0035] The main parts involved in the lifting massage head are: a mounting seat 1, a rotating wheel 2, a screw 3, a massage assembly 4, a spring 5 and a friction plate 6. The rotating wheel 2 is rotatably mounted in the mounting seat 1, the middle part of the rotating wheel 2 has a threaded hole, the screw 3 is threadedly connected to the threaded hole along the axial direction of the rotating wheel 2, and the upper end of the screw 3 passes through the mounting seat 1, the massage assembly 4 includes a support plate 4a, the upper side of the support plate 4a is mounted with a first massage head 4b and a second massage head 4c, wherein the first massage head 4b is fixedly connected to the support plate 4a, and the second massage head 4c is rotatably connected to the support plate 4a, the support plate 4a of the massage assembly 4 is fixedly connected to the upper end of the screw 3, the spring 5 is preferably a tower-shaped spring, the large diameter end of the tower-shaped spring is fixed on the mounting seat 1, and the small diameter end is frictionally abutted on the lower surface of the friction plate 6, and the lower end of the screw 3 is fixedly mounted with a limit plate 3a.

[0036] like Figure 7 As shown, the working principle of the waist massage device applied to the seat back 9 is:

[0037] The rotating shaft 7b of the driving assembly 7 is rotatably mounted in the supporting assembly 8, and the rotating shaft 7b is provided with a gear 7c which drives the two sets of lifting massage heads to work respectively, and the gear 7c is connected to the corresponding rotating wheel 2. When the waist massage device is not in use, the spring 5 is in a highly compressed state, and there is a minimum distance between the friction plate 6 and the mounting seat 1. At this time, the first massage head 4b and the second massage head 4c are away from the waist position of the driver and the passenger, and do not come into contact, so that the safety of the seat can be ensured without being affected by the massager. When the user needs to use the massage function, the drive assembly 7 works, the motor 7a drives the rotating shaft 7b to rotate in the support assembly 8 through the reducer 7d, and then the gear 7c drives the meshing rotating wheel 2 to rotate. Since the spring 5 is supported between the friction plate 6 and the mounting seat 1, the rotation of the rotating wheel 2 will drive the screw 3 to rise, so that the massage assembly 4 rises to the waist position of the driver and passenger. After the massage assembly 4 rises to the waist position, the limit plate 3a abuts against the lower end of the rotating wheel 2, and the screw 3 no longer rises further, but rotates synchronously with the rotating wheel 2. The massage assembly 4 starts to rotate at this time. During the rotation of the massage assembly 4, the first massage head 4b revolves relative to the center line of the screw 3, and the second massage head 4c revolves and rotates relative to the center line of the screw 3, thereby realizing massage, kneading and other operations on the waist, which can fully relieve the fatigue of the waist of the driver and passenger who sits for a long time. After the massage is over, the reverse movement of the drive assembly 7 can make the first massage head 4b and the second massage head 4c leave the waist position of the driver and passenger.

[0038] like Figure 2 , 3 As shown, for easy installation, the upper end of the rotating wheel 2 has a rotating boss 2b, and the lower end has a countersunk hole 2a. The mounting seat 1 has a mounting hole 1a at the position corresponding to the rotating boss 2b, and an annular boss 1b at the position corresponding to the countersunk hole 2a. After the rotating wheel 2 is installed, the rotating boss 2b is rotatably installed in the mounting hole 1a, and the countersunk hole 2a is rotatably mounted on the annular boss 1b. When the screw 3 rises to the highest position, in order to make the limiting piece 3a abut against the countersunk hole 2a, the diameter of the limiting piece 3a is smaller than the inner diameter of the countersunk hole 2a.

[0039] A driving wheel mounting groove 1c is provided in the mounting seat 1 at a position corresponding to one side of the rotating wheel 2, and the gear 7c is installed in the driving wheel mounting groove 1c. In this embodiment, the gear 7c and the rotating wheel 2 are both helical gears. In addition, the gear 7c and the rotating wheel 2 can also be replaced by a worm gear.

[0040] Further, such as Figure 1 and 2As shown, in order to facilitate the fixed assembly of the support plate 4a and the upper end of the screw rod 3, the middle part of the support plate 4a has a protrusion 4a1 extending upward, and the protrusion 4a1 is a hollow structure with an open lower end. Locking notches 4a2 are provided on both sides of the protrusion 4a1. When assembling the lifting massage head, first extend the upper end of the screw rod 3 into the protrusion 4a1, and then insert a locking pin 3b from the locking notch 4a2 along the radial direction of the screw rod 3 to achieve fixed assembly.

[0041] Furthermore, a fixing seat 4a3 and an adapter seat 4a4 are provided at positions on both sides of the support plate 4a corresponding to the protruding portion 4a1. The first massage head 4b is fixedly mounted on the fixing seat 4a3, and the second massage head 4c is rotatably connected to the adapter seat 4a4. To ensure the smooth rotation of the second massage head 4c, a positioning hole 4a5 is provided in the middle of the adapter seat 4a4, and the second massage head 4c is provided with an inner positioning column 4c1 adapted to the positioning hole 4a5.

[0042] like Figure 2 As shown, to ensure the comfort of massage, the outer ends of the first massage head 4b and the second massage head 4c are both arc-shaped structures, and the upper end of the first massage head 4b is higher than the upper end of the second massage head 4c.

[0043] The lower end of the spring 5 provided in this embodiment is fixedly connected to the mounting seat 1, and the upper end is in frictional contact with the friction plate 6; in addition, the friction plate 6 can also be arranged at the lower end of the spring 5, that is: the lower end of the spring 5 is in frictional contact, and the upper end is fixedly connected.

[0044] 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.
