Description

Technical Field

[0001] This utility model relates to the field of massage technology, and more specifically, to a sofa with massage function. Background Technology

[0002] A massage sofa is a multifunctional piece of furniture that combines the comfort of a traditional sofa with massage technology. It is designed to provide users with a relaxing and fatigue-relieving experience, helping to soothe muscle tension, relax the body, and increase comfort. Massage devices are usually embedded in the sofa structure. It is suitable for use in homes, offices, and other settings, and is designed to target areas of muscle tension such as the lower back, promoting blood circulation. It is suitable for people who sit for long periods of time.

[0003] Chinese Patent Announcement No. CN217013309U provides a massage sofa. In this design, the massage head assembly is slidably connected to the mounting base via a guide rail slider assembly. One end of the connecting rod is hinged to the massage head assembly, and the other end is hinged to the non-central position of the massage wheel. The drive end of a small displacement motor is connected to the massage wheel to rotate it. After the massage wheel rotates, the connecting rod moves up and down accordingly, thereby causing the massage head assembly to slide back and forth slightly.

[0004] However, the massage methods described above can only perform translational squeezing, which means that pressure can only be applied in a fixed direction (such as up and down or left and right). This only achieves simple movements, lacks variation, and is not conducive to improving the massage effect.

[0005] Therefore, a sofa with massage function is proposed to address the above problems. Utility Model Content

A rack is fixedly installed on one side inside the fixed frame. The gears mesh with the rack. The drive block, driven by the rotor, causes the gears to move linearly along the rack while simultaneously rotating.

[0011] The technical solutions described in this application embodiment have at least the following technical effects:

[0012] The shell is installed on the back of the sofa body. By rotating the rotor, the edge of the rotor can squeeze the drive block, which in turn drives the gear to move. Since the gear is meshed with the rack, the moving gear will also rotate. So when you lean against the outer cover of the shell, the moving gear can not only drive the massage head to move and squeeze to massage the waist and back, but also perform kneading motions through rotation, which can more effectively relieve muscle stiffness and improve the massage effect.

[0013] In some embodiments, a cover is detachably mounted on the outer end of the housing, a through hole is provided on the outer end of the cover, an outer sleeve is fixedly mounted on the outer end of the cover, and the top of the massage head passes through the through hole and abuts against the inner side of the outer sleeve.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1 - Figure 8 A sofa with a massage function includes a sofa body 1. Multiple housings 4 are installed on the back of the sofa body 1. A drive assembly 6 is installed inside the housing 4. Two massage components 5 are installed inside the drive assembly 6. The massage component 5 includes a drive block 54 and two gears 55. Multiple massage heads 56 are installed on the outer ends of the two gears 55. The two gears 55 are rotatably mounted on the top of the drive block 54. The drive assembly 6 includes a fixing frame 61 and a rotor 62. A rack 63 is fixedly installed on one side inside the fixing frame 61. The gears 55 are meshed with the rack 63. The drive block 54 is pushed by the rotor 62 to drive the gears 55 to move linearly along the rack 63 while rotating.

[0037] The outer end of the housing 4 is detachably fitted with a cover 2. The outer end of the cover 2 has a through hole. The outer end of the cover 2 is fixedly fitted with a jacket 3. The top of the massage head 56 passes through the through hole and abuts against the inner side of the jacket 3.

[0038] The device in this design differs from traditional sofas in that it incorporates a massage mechanism in the backrest, allowing for a massage experience while reclining. The housing 4 is embedded in the backrest of the sofa body 1 and can be detachably secured using built-in clips. Inside the housing 4 is a drive assembly 6, on the inner side of which are two symmetrically mounted massage components 5. The drive assembly 6 primarily powers the massage components 5, which in turn massage the lower back.

[0039] A cover 2 is detachably installed on the outside of the housing 4. The cover 2 can be installed by screws or clips. A through hole is opened in the middle of the cover 2. An outer cover 3 is also fixed to the outside of the cover 2. The outer cover 3 is made of leather or cloth and has soft and deformable properties. The outer cover 3 can be fixed to the outside of the cover 2 by glue or rivets, and at the same time, it covers the through hole opened on the cover 2. The through hole is mainly used to allow the massage component 5 to pass through. Then, the massage head 56 in the massage component 5 abuts against the outer cover 3. By rotating the rotor 62, the edge of the rotor 62 can squeeze the drive block 54, thereby causing the drive block 54 to drive the gear 55 to move. Since the gear 55 is meshed with the rack 63, the moving gear 55 will also rotate. Therefore, when it is against the outer cover 3 outside the housing 4, the moving gear 55 can not only drive the massage head 56 to move and squeeze to massage the waist and back, but also perform a kneading action by rotating, which can more effectively relieve muscle stiffness and improve the massage effect.

[0040] Please see Figure 4 - Figure 6 The mounting bracket 61 is fixedly installed inside the housing 4. The rotor 62 includes a cam block 621 and a rotating shaft 622. The rotating shaft 622 extends through the inner wall of the housing 4 to the outside. A power device 7 is installed at the outer end of the housing 4. The output end of the power device 7 is connected to the rotating shaft 622.

[0041] The cam block 621 is fixedly installed on the top of the rotating shaft 622. The cam block 621 is arranged in an equilateral triangle, and grooves are provided on all three outer sides of the cam block 621. The outer end of the drive block 54 abuts against the outer side of the cam block 621.

[0042] In this design, the mounting bracket 61 is in the shape of a ring-shaped racetrack. The mounting bracket 61 is fixed to the inner wall of the housing 4 by the bottom bracket, so that there is a certain space between the mounting bracket 61 and the bottom of the housing 4. The rack 63 is fixed inside the mounting bracket 61. It is worth mentioning that the long rack 63 is fixed on only one side of the inner side of the mounting bracket 61, while the rotor 62 is located in the middle of the mounting bracket 61.

[0043] The rotor 62 is mainly composed of a cam block 621 and a rotating shaft 622. The cam block 621 is similar in shape to an equilateral triangle. Grooves are provided on the three sides of the cam block 621. The grooves cause each side of the cam block 621 to extend in an arc shape from the central concave part to both sides. The three grooves are connected together in sequence.

[0044] The rotating shaft 622 is mainly used to install the cam block 621. The cam block 621 is fixedly installed on the top of the rotating shaft 622. The other end of the rotating shaft 622 extends through the housing 4 to the back of the housing 4. The power device 7 is installed on the back of the housing 4. The power device 7 is mainly used to drive the rotating shaft 622 to rotate. The power device 7 consists of a drive motor, multiple reduction gears, and a transmission shaft. The output end of the motor is connected to the reduction gears, and the multiple reduction gears mesh in sequence to reduce the speed and increase the torque of the power output by the motor. Then, the last output gear is connected to the transmission shaft. The rotating shaft 622 is driven by the power device 7 through the connection with the transmission shaft. When the power device 7 drives the rotating shaft 622 to rotate, the cam block 621 will rotate with the rotating shaft 622, thereby driving the massage component 5.

[0045] Please see Figure 4 , Figure 5 , Figure 7 as well as Figure 8 The massage component 5 also includes a fixed shell 51, which is fixedly installed on the inner wall of the housing 4. A sliding groove 52 is provided inside the fixed shell 51. A slider 53 is fixedly connected to the bottom of the drive block 54, and the slider 53 is slidably connected to the sliding groove 52.

[0046] The massage component 5 also includes a telescopic spring 57, which is located inside the slide groove 52. The two ends of the telescopic spring 57 abut against the inner side wall of the slide groove 52 and the outer end of the slider 53, respectively. The telescopic spring 57 pushes the slider 53 with elastic force to drive the drive block 54 to abut against the cam block 621.

[0047] The massage head 56 includes a mounting post 561 and a steel ball 563. The mounting post 561 is fixedly mounted on the outer end of the gear 55. The top of the mounting post 561 has a mounting groove 562 that is adapted to the steel ball 563. The steel ball 563 is mounted inside the mounting groove 562.

[0048] The massage component 5 in this solution is mainly used to massage the lower back through the outer cover 3. The fixed shell 51 is fixed to the inner wall of the shell 4. A sliding groove 52 is provided inside the fixed shell 51. The sliding groove 52 matches the slider 53, so that the slider 53 can slide in the sliding groove 52. The top of the slider 53 passes through the fixed shell 51 and extends to the outside of the fixed shell 51, and is fixedly connected to the drive block 54. That is to say, the drive block 54 is located outside the fixed shell 51. A telescopic spring 57 is also installed inside the sliding groove 52. The two ends of the telescopic spring 57 abut against one end of the slider 53 and the inner wall of the sliding groove 52, respectively. Thus, the slider 53 can be pushed towards the drive component 6 by the force of the telescopic spring 57.

[0049] At the top of the drive block 54, two gears 55 are rotatably mounted. There is a gap between the two gears 55 so that they do not mesh. Multiple massage heads 56 are fixedly mounted on the outer end of each gear 55. The massage heads 56 are mainly used to press against the user's back through the outer cover 3, thereby massaging the back through rotation and movement.

[0050] Due to the force of the telescopic spring 57, the slider 53 drives the drive block 54 to move towards the rotor 62, ensuring that one end of the drive block 54 always rests against the outer edge of the cam block 621. Because the outer edge of the cam block 621 has three grooves, the stroke of the drive block 54 is increased. When the power unit 7 drives the rotor 62 to rotate, the cam block 621 pushes the drive block 54 through its own edge, causing the slider 53 to compress the telescopic spring 57. At this time, the drive block 54 also drives the gear 55 to move. Simultaneously, since the gear 55 meshes with the rack 63... The connection allows the moving gear 55 to rotate as well. Driven by the rotor 62, the gear 55 rotates while moving. Through the cooperation of the uneven outer edge of the cam block 621 and the telescopic spring 57, the gear 55 can move back and forth in a straight line while rotating in both directions. This allows the massage head 56 to perform kneading motions through the combination of translation and rotation. Compared to traditional massage methods that can only perform translation and squeezing, this method can combine various techniques such as kneading, acupressure, and rolling, mimicking human hand movements, resulting in more even pressure distribution and improved massage effect.

[0051] The massage head 56 is mainly composed of a mounting post 561 and a steel ball 563. The mounting post 561 is fixedly mounted on the outer end of the gear 55. The mounting post 561 has a mounting groove 562 on its top, which matches the steel ball 563, allowing the steel ball 563 to be installed inside the mounting groove 562. At the same time, the steel ball 563 can also rotate inside the mounting groove 562, making it similar to the structure of a pen tip. Since the steel ball 563 abuts against the outer sleeve 3, pushing the outer sleeve 3 outward to press against the user's back, the smooth steel ball 563 and its ability to rotate within the mounting groove 562 reduce the friction with the outer sleeve 3 and improve the smoothness of the movement when the massage head 56 moves or rotates.

[0052] Working principle: When using this device, it only needs to be placed against the outer cover 2 of the housing 4. Due to the force of the telescopic spring 57, one end of the drive block 54 will always be pressed against the outer edge of the cam block 621. Since the outer edge of the cam block 621 has three grooves, it is uneven. When the power device 7 drives the rotating shaft 622 to rotate, the cam block 621 will rotate with the rotating shaft 622. The edge of the cam block 621 will push the drive block 54 to move. At the same time, the drive block 54 will also drive the gear 55 to move. Since the gear 55 is meshed with the rack 63, the moving gear 55 will also rotate. Thus, driven by the rotor 62, the gear 55 can rotate while moving, performing a kneading action to improve the massage effect.
