Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a suspended flexible shell and massage backrest of a massage backrest mechanism. Background Technology

[0002] Most backrest massage mechanisms on the market use a locking mechanism to fix the rack to the shell, resulting in high rigidity and a lack of flexibility. The rack cannot adapt to the curves of the human back to conform to the backrest, leading to a stiff and rigid massage that severely impacts comfort. To address this issue, the industry has proposed flexible structures. For example, Chinese patent application CN202520856807.9 discloses a novel flexible massage mechanism, comprising: an integrated frame, a track assembly, and a massage mechanism. The track assembly is located in the middle of the integrated frame, and the massage mechanism travels on the track assembly. An elastic device is provided between the integrated frame and the track assembly.

[0003] However, this technical solution still has limitations. The unibody frame structure makes it difficult to flexibly adjust its appearance. When facing diverse appearance design requirements from different customers, multiple sets of molds need to be developed to match customer needs, increasing production costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a suspended flexible shell and massage backrest for a massage backrest mechanism, which can reduce the development cost of custom molds for appearance.

[0005] This utility model is implemented as follows:

[0006] In the first aspect, this utility model provides a suspended flexible housing for a massage backrest mechanism, including an outer frame. The outer frame is provided with several sets of breaks, so that the outer frame is divided into several frame units, and the frame units are connected by connecting components.

[0007] Furthermore, the connecting component is a deformable connector, which is divided into several groups and is detachably installed at the break point.

[0008] Furthermore, the connector is a first connector that is straight or curved, and the thickness of the first connector is less than the thickness of the outer frame.

[0009] Furthermore, the connector is a second connector with a corrugated or folded structure.

[0010] Furthermore, the break is set in two groups, so that the outer frame is divided into a left border unit, a middle border unit, and a right border unit.

[0011] Furthermore, the connecting component includes a middle plate, and the two ends of the middle plate are connected to a third elastic connector with a corrugated or folded structure. The third elastic connector is connected to the middle frame unit. The left and right frame units are respectively provided with partitions. The partitions are connected to a fourth elastic connector with a corrugated or folded structure. The fourth elastic connector is connected to the middle plate.

[0012] Furthermore, the middle part of the middle plate is recessed, dividing the middle plate into a recessed area and a wingspan area. The third elastic connector is connected to the recessed area, and the fourth elastic connector is connected to the wingspan area.

[0013] Furthermore, it also includes a rack, which is integrally formed on the side of the wingspan area.

[0014] Furthermore, several hollowed-out grooves are provided at the corner where the sunken area and the wingspan area connect.

[0015] Secondly, this utility model provides a massage backrest, including a suspended flexible shell as described in the first aspect.

[0016] The advantages of this utility model are:

[0017] 1. By dividing the outer frame into several border units, the left and right areas on the mold corresponding to the left and right border units can be set as replaceable inserts. Various shapes and appearances can be made according to customer requirements. When in use, only one outer cover is needed to shape various appearances without the need for additional sponge filling. The same mold can meet the different appearance requirements of multiple customers, eliminating the need to open a mold for each customer, which significantly reduces the mold development cost.

[0018] Additionally, when customers only need the central frame unit, the inserts on the left and right sides of the mold can be replaced with solid ones. After the shell is molded as a single piece, only the central frame unit is molded separately, which can be used independently and locked onto the back of the sofa massage chair, achieving flexible disassembly and reuse.

[0019] 2. In addition, the left and right side frame units are connected to the middle side frame unit by elastic connectors, which allows the flexible shell to adapt to different massage sofa frames. With the left and right side frame units fixed, the height of the middle side frame unit can be flexibly adjusted to match various massage sofa structures and broaden the product's applicability.

[0026] Example 1, please refer to Figures 1 to 3 This utility model provides a suspended flexible shell for a massage backrest mechanism, including an outer frame 1. The outer frame 1 is provided with several sets of breaks 2, which are arranged along the longitudinal direction of the outer frame 1, so that the outer frame 1 is divided into several frame units, and the frame units are connected by connecting components.

[0027] By dividing the outer frame 1 into several border units (such as three), the left and right areas on the mold corresponding to the left border unit 11 and the right border unit 13 can be set as replaceable inserts. Various shapes and appearances can be made according to customer requirements. When in use, only one outer cover is needed to shape various appearances without the need for additional sponge filling. The same mold can match and meet the different appearance requirements of multiple customers, eliminating the need to open a mold for each customer, which significantly reduces the mold development cost.

[0028] Specifically, the break 2 is preferably set in two groups, so that the outer frame 1 is divided into a left border unit 11, a middle border unit 12, and a right border unit 13. Of course, the outer frame 1 can also be divided into more border units.

[0029] Example 2, please refer to Figures 2 to 3 This utility model provides a suspended flexible shell for a massage backrest mechanism. Based on the technical solution of Embodiment 1, the connecting component is a deformable connector made of flexible material. The connector is divided into several groups, each detachably installed at the break point 2. The connector is locked at the break point 2.

[0030] The left and right side frame units are connected to the middle frame unit 12 via deformable connectors, allowing the flexible shell to adapt to different massage sofa frames. With the left side frame unit 11 and right side frame unit 13 fixed, the height of the middle frame unit 12 can be flexibly adjusted to easily match various massage sofa structures, thus broadening the product's applicability. The connectors are made of elastic or flexible materials.

[0031] In this embodiment, the elastic connector has two structures:

[0032] 1. The connecting member is a first connecting member 3 that is straight or curved, and the thickness of the first connecting member 3 is less than the thickness of the outer frame 1. In addition to being able to flexibly adjust the height of the middle frame unit 12, the first connecting member 3 can also be freely bent and deformed, so that the left frame unit 11, the middle frame unit 12 and the right frame unit 13 can be assembled at a certain angle as required.

[0033] 2. The connecting member is a second connecting member 4 with a corrugated or folded structure.

[0034] In this invention, the second connector 4, the third elastic connector 6, and the fourth elastic connector 8 are all corrugated or folded structures. In this application, folded refers to a V-shape or a zigzag shape; furthermore, the shapes of the second connector 4, the third elastic connector 6, and the fourth elastic connector 8 can be the same or different.

[0035] In this embodiment, the suspended flexible shell also includes a middle plate, with a rack formed on the side of the middle plate. The connection structure between the middle plate and the outer frame can adopt the structure in the prior art, which will not be described in detail here.

[0036] Example 3, please refer to Figure 1 This utility model provides a suspended flexible shell for a massage backrest mechanism. Based on the technical solution of Embodiment 1, the connecting component includes a middle plate 5. The two ends of the middle plate 5 are connected to a third elastic connector 6 with a corrugated or folded structure. The third elastic connector 6 is connected to the middle frame unit 12. The left frame unit 11 and the right frame unit 13 are respectively provided with partitions 7. The partitions 7 are connected to a fourth elastic connector 8 with a corrugated or folded structure. The fourth elastic connector 8 is connected to the middle plate 5.

[0037] The middle frame unit 12, the third elastic connector 6 and the middle plate 5 are preferably integrally formed, and the left frame unit 11 or the right frame unit 13, the partition 7, the fourth elastic connector 8 and the middle plate 5 are preferably integrally formed.

[0038] In this embodiment, the partition 7 is inclined downward and located at the bottom of the walking massage mechanism (not shown in the figure). The partition 7 is used to isolate the walking massage mechanism from the flexible sleeve (such as a leather sleeve or cloth sleeve) wrapped around the outside of the massage backrest, avoiding direct contact between the bottom of the walking massage mechanism and the outer cloth sleeve (leather sleeve), preventing the leather sleeve from being worn through, saving the wear-resistant cloth layer on the inner surface of the leather sleeve, greatly optimizing the process, procedures and material quantity, improving production efficiency, reducing costs and increasing service life.

[0039] In this embodiment, the third and fourth elastic connectors are arranged along the Y-axis and X-axis directions, respectively, allowing the middle plate 54 to deform freely in both the X and Y directions. In the second embodiment, the first or second connector is used to flexibly adjust the height of the middle frame unit 12 when the left frame unit 11 and the right frame unit 13 are fixed, making it easy to match with various massage sofa structures and broadening the product's applicability.

[0040] In this embodiment, by providing the third and fourth elastic connectors 8, the middle plate 5 can float up and down relative to the outer frame 1 during use, maintaining a relatively constant massage force. Under heavy pressure, the elastic connectors will deform downwards, reducing the massage force; under light load, the elastic connectors will return to their initial position.

[0041] Specifically, the middle part of the middle plate 5 is recessed, dividing the middle plate 5 into a recessed area 51 and a wingspan area 52. The third elastic connector 6 is connected to the recessed area 51, and the fourth elastic connector 8 is connected to the wingspan area 52.

[0042] Specifically, it also includes a rack 9, which is integrally formed on the side of the wingspan area 52. The gears on the walking massage mechanism mesh with the rack 9 to drive the walking massage mechanism to move along the extension direction of the rack 9.

[0043] Specifically, several hollowed-out grooves 53 are provided at the corner where the sunken area 51 and the wingspan area 52 connect. The hollowed-out grooves 53 can reduce the rigid constraint on the rack 9, making the rack 9 more flexible and more capable of free deformation.

[0044] Specifically, the wing area 52 is also provided with a guide groove 54 for guiding the movement of the walking massage mechanism.

[0045] Example 4, please refer to Figures 1 to 3 This utility model provides a suspended flexible shell for a massage backrest mechanism. Based on the technical solution of Embodiment 1, the connecting component is a deformable connector made of flexible material. The connector is divided into several groups, which are detachably installed at the break 2.

[0046] Specifically, the connector is a first connector 3 that is straight or curved, and the thickness of the first connector 3 is less than the thickness of the outer frame 1.

[0047] Specifically, the connector is a second connector 4 with a corrugated or folded structure.

[0048] Specifically, the break 2 is set in two groups, so that the outer frame 1 is divided into a left side frame unit 11, a middle side frame unit 12 and a right side frame unit 13.

[0049] Specifically, the connecting component includes a middle plate 5, with a third elastic connector 6 having a corrugated or folded structure at both ends of the middle plate 5. The third elastic connector 6 is connected to the middle frame unit 12. The left frame unit 11 and the right frame unit 13 are respectively provided with partitions 7. The partitions 7 are connected to a fourth elastic connector 8 having a corrugated or folded structure. The fourth elastic connector 8 is connected to the middle plate 5.

[0050] Specifically, the middle part of the middle plate 5 is recessed, dividing the middle plate 5 into a recessed area 51 and a wingspan area 52. The third elastic connector 6 is connected to the recessed area 51, and the fourth elastic connector 8 is connected to the wingspan area 52.

[0051] Specifically, it also includes a rack 9, which is integrally formed on the side of the wingspan area 52.

[0052] Specifically, several hollowed-out grooves 53 are provided at the corner where the sunken area 51 and the wingspan area 52 connect.

[0053] This embodiment of the suspended flexible shell, while meeting the diverse appearance requirements of multiple customers with a single mold, significantly reduces mold development costs by eliminating the need for a separate mold for each customer, and combines the technical advantages of embodiments two and three. With the left and right side frame units 11 and 12 fixed, the height of the middle side frame unit 12 can be flexibly adjusted, facilitating compatibility with various massage sofa structures and broadening the product's applicability. It also allows the middle plate 5 to float vertically relative to the outer frame 1, maintaining a relatively constant massage intensity. Under heavy pressure, the elastic element deforms, reducing the massage intensity; under light load, the elastic element returns to its initial position.

[0054] Example 5: This utility model provides a massage backrest, including the suspended flexible shell described in any one of Examples 1 to 4.
