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 commercially available backrest massage mechanisms 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, causing a stiff and rigid massage that severely impacts comfort. To address this issue, the industry has proposed flexible structures. For example, Chinese patent application CN202421703757.2 discloses a suspended massage cushion, including a walking massage mechanism and a pair of rack rails. The walking massage mechanism is held between the rack rails on both sides, with the rack rails providing support. The pair of rack rails are mounted on a central plate, and a support frame is located outside the central plate. At least one end of the central plate is connected to the support frame via an elastic structure. This patent integrates at least one rack rail onto a central plate, with one or both ends of the central plate connected to the support frame via an elastic structure. This allows the central plate, carrying the walking massage mechanism, to float up and down relative to the support frame, adapting to changes in the human body's curves and maintaining a relatively constant massage intensity. Combined with a central plate and support frame made of flexible material, it can also conform to the chair back.

[0003] Generally, a flexible sleeve covers the massage backrest, serving both decorative and dust-proof purposes. However, this flexible fabric is prone to getting caught in the rack and pinion rails. To prevent this technical problem, anti-pinch strips are installed at the edges of the support frame, supporting the bottom of the walking massage mechanism and creating an isolation effect on the covered fabric. However, since the entire shell is flexible and deformable, when the walking massage mechanism is subjected to force on one side, it is easy for it to tilt and jump off to the back of the anti-pinch strip (i.e., be squeezed against the back of the anti-pinch strip), causing the bottom of the walking massage mechanism to come into direct contact with the inner surface of the flexible sleeve, thus wearing through the flexible sleeve. 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 prevent the mechanism from tilting and jumping off one side and wearing out the flexible sleeve when the massage mechanism is subjected to force on one side.

[0005] This utility model is implemented as follows:

[0006] In a first aspect, this utility model provides a suspended flexible housing for a massage backrest mechanism, including an outer frame and a partition disposed on the inner side of the outer frame. The partition is located at the bottom of the walking massage mechanism and is used to isolate the walking massage mechanism and the flexible sleeve. The flexible housing also includes at least one strip-shaped member, the two ends of which are respectively connected to the partition.

[0007] Furthermore, the strip is detachably connected to the partition, and each partition has a fixing hole, at which the strip is fixed.

[0008] Furthermore, the strip-shaped component is integrally formed at the bottom of the partition.

[0009] Furthermore, it also includes a middle plate and a rack, the rack being formed on the side edge of the middle plate, and the middle plate being connected to the inner side of the outer frame by an elastic element.

[0010] Furthermore, the elastic element, the middle plate, and the outer frame are integrally formed.

[0011] Furthermore, the elastic element includes at least a first elastic connector in the form of corrugations, one end of which is connected to the outer frame and the other end of which is connected to the middle plate.

[0012] Furthermore, the elastic element also includes a second elastic connector in the form of corrugations, one end of which is connected to the partition plate and the other end of which is connected to the side of the middle plate.

[0013] Furthermore, the middle part of the middle plate is recessed, dividing the middle plate into a recessed area and a wingspan area. The rack is formed in the wingspan area, and several hollow grooves are provided at the corner where the recessed area and the wingspan area connect.

[0014] Furthermore, the wing area is also provided with guide grooves for guiding the movement of the walking massage mechanism.

[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 invention are as follows: In the prior art, because the partition is made of flexible material, the walking massage mechanism is easily squeezed to the back of the partition when subjected to force on one side. In this application, however, the strip-shaped member effectively constrains the walking massage mechanism, limiting its excessive tilting when subjected to force on one side and preventing it from tilting and jumping off to the back of the partition. This solves the problem of the bottom of the walking massage mechanism directly contacting the inner surface of the flexible sleeve and wearing it down. Attached Figure Description

[0022] Example 1, please refer to Figures 1 to 2 This utility model provides a suspended flexible shell for a massage backrest mechanism, including an outer frame 1 and a partition 2 disposed inside the outer frame 1, the partition 2 being inclined downwards; the outer frame 1 and the partition 2 are integrally formed by elastic material, the partition 2 being located at the bottom of the walking massage mechanism (not shown in the figure), 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;

[0023] The flexible shell also includes at least one strip 3, which is made of flexible material or metal material, and its two ends are respectively connected to the partition 2. When the number of strips 3 is set to one, the strip 3 is connected to the middle of the partition 2. When the number of strips 3 is set to several, the strips 3 are arranged at intervals on the partition 2.

[0024] By constraining the walking massage mechanism with strip 3, excessive tilting of the walking massage mechanism can be limited when it is subjected to force on one side, so as to avoid the problem of the walking massage mechanism tilting on one side and jumping off to the back of the partition 2.

[0025] Specifically, the strip-shaped member 3 is detachably connected to the partition 2. Each partition 2 has a fixing hole 21, the number and size of which match the strip-shaped member 3. The strip-shaped member 3 is fixed at the fixing hole 21. The fixing methods for the strip-shaped member 3 and the fixing hole 21 can be as follows:

[0026] 1. After the end of the strip 3 passes through the fixing hole 21, it is folded in half and fixed by sewing.

[0027] 2. After the end of the strip 3 passes through the fixing hole 21, it is directly nailed to the partition 2 with a nail gun.

[0028] 3. Secure with screws. After the end of the screw passes through the fixing hole 21 and the strip 3, tighten the nut to secure the strip 3. Alternatively, secure the strip 3 with self-tapping screws.

[0029] 4. The strip 3 is fixed to the partition 2 by hot-melt connection.

[0030] 5. After the end of the strip 3 passes through the fixing hole 21, it is fixed by Velcro, Velcro or other fasteners (such as the form of male and female fasteners).

[0031] Specifically, the strip-shaped member 3 is integrally formed at the bottom of the partition 2.

[0032] Specifically, it also includes a middle plate 4 and a rack 5, the rack 5 being formed on the side edge of the middle plate 4, and the middle plate 4 being connected to the inner side of the outer frame 1 by an elastic element. By providing the elastic element, the middle plate 4 can float up and down relative to the support frame, maintaining a relatively constant massage force. Under heavy pressure, the elastic element will deform downwards, reducing the massage force; under light load, the elastic element returns to its initial position. In this application, the elastic element is arranged along the X and Y axes, allowing the middle plate 4 to deform freely in both the X and Y directions.

[0033] Specifically, the elastic element includes at least a first elastic connector 6 in a corrugated shape, one end of which is connected to the outer frame 1 and the other end of which is connected to the middle plate 4. The first elastic connector 6 is arranged along the Y-axis direction.

[0034] Specifically, the elastic element further includes a second elastic connector 7 in the form of corrugations and pleats. One end of the second elastic connector 7 is connected to the partition plate 2, and the other end is connected to the side of the middle plate 4. The second elastic connector 7 is arranged along the X-axis direction.

[0035] Specifically, the elastic element, the middle plate 4, and the outer frame 1 are integrally formed.

[0036] Specifically, the middle plate 4 is recessed in the middle, dividing the middle plate 4 into a recessed area 41 and a wingspan area 42. The rack 5 is formed in the wingspan area 42, and several hollow grooves 8 are provided at the corner where the recessed area 41 and the wingspan area 42 connect, so as to reduce the rigid constraint on the rack 5, making the rack 5 more flexible and more free to deform.

[0037] One end of the first elastic connector 6 is connected to the outer frame 1, and the other end is connected to the sunken area 41;

[0038] Specifically, the wing area 42 is also provided with a guide groove 43 for guiding the movement of the walking massage mechanism.

[0039] Example 2: This utility model provides a massage backrest, including the suspended flexible shell described in Example 1.

[0040] The advantages of this utility model are as follows: In this application, the strip 3 forms an effective constraint on the walking massage mechanism. When the walking massage mechanism is subjected to force on one side, it can limit its excessive tilting and prevent the walking massage mechanism from tilting to one side and jumping off to the back of the partition 2. This solves the problem of the bottom of the walking massage mechanism directly contacting the inner surface of the flexible sleeve and wearing out the flexible sleeve.
