Description

Technical Field

[0001] The invention relates to a sofa massage chair frame with a T-type backrest mechanism, which has the comfort of a sofa and sufficient massage function. Background Art

[0002] A sofa is a soft furniture with soft cushions. To ensure the support of the sofa back support, the existing sofa back support is generally provided with a corresponding backrest board, and then the cushion is installed on the backrest board. Under the obstruction of the backrest board, the existing sofa cannot be installed with a massage mechanism. Even if a small number of sofas have massage mechanisms, they can only be installed as a local fixed massage mechanism at the position of the back support without the backrest board, and a reasonable massage effect cannot be achieved at all.

[0003] Even some existing massage structures that use back support often use a whole piece of support structure that fits most areas of the human back, directly supporting the entire back or a large area of ​​the user's back to achieve the support effect. However, if this support structure is used, the massage movement needs to sink for a long time to make way for the back support structure, and the user's blank period during the massage is long, which affects the overall experience.

[0004] Therefore, on the basis of retaining the back support requirements of the sofa and ensuring its comfort, the research purpose of the present invention is to design a sofa massage chair frame that can effectively carry out a mobile massage mechanism setting, so as to maintain the comfort of the sofa and achieve a reasonable massage effect. Summary of the invention

[0005] In view of the technical problems existing in the above-mentioned prior art, the present invention provides a sofa massage chair frame with a T-type backrest mechanism, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is:

[0007] A sofa massage chair frame with a T-type backrest mechanism, comprising

[0008] The massage chair frame bracket is composed of a set of side support frames arranged side by side;

[0009] The T-shaped auxiliary support mechanism comprises a transverse support member fixedly connected between the upper sides of the set of side support frames, wherein the transverse support member is vertically locked with a longitudinal support member extending along the direction of the human spine;

[0010] The massage movement mechanism includes a massage mechanism, a reciprocating drive mechanism for driving the massage mechanism to reciprocate between a set of side support frames, and a vertical drive mechanism for driving the massage mechanism to move vertically between the set of side support frames. When the massage mechanism reciprocates past the horizontal support member, under the drive of the vertical drive mechanism, the massage mechanism descends until its massage wheels are located on the bottom side of the horizontal support member. When the massage mechanism reciprocates away from the horizontal support member, under the drive of the vertical drive mechanism, the massage mechanism ascends until its massage wheels are located on the upper side of the horizontal support member.

[0011] At the bottom of the side support frames, a corresponding guiding drive rack and a guiding groove are respectively provided at different heights. The reciprocating drive mechanism includes a moving housing, the massage mechanism is installed on the moving housing, a drive shaft and a fixed shaft are respectively connected to the front and rear ends of the moving housing. The drive shaft is driven by a corresponding reciprocating drive motor, and drive gears meshingly connected to the guiding drive rack are respectively fixed at both ends of the drive shaft. Both ends of the fixed shaft are respectively slidably installed in the guiding groove.

[0012] The massage mechanism includes a swing housing whose one end is swingably connected to the moving housing. A set of corresponding massage arms are swingably and upwardly connected to the end of the swing housing that is not connected to the moving housing. The massage wheels are respectively rotatably installed on the massage arms. The massage arms are driven by a massage drive mechanism installed in the swing housing.

[0013] The vertical drive mechanism includes a downward pressure drive shaft fixedly installed at the end of the swing housing that is not connected to the moving housing, and a set of guiding convex edges fixedly installed on the side support frame under the bottom side of the horizontal support member. One end of the moving housing that is not connected to the swing housing is upwardly connected with a compressible elastic member for pushing the swing housing to swing upward. When the swing housing swings upward, the massage wheels ascend to the upper side of the horizontal support member. When the swing housing of the massage mechanism passes the horizontal support member, the downward pressure drive shaft moves downward under the drive of the guiding convex edges, and the massage mechanism is pressed downward until its massage wheels are located on the bottom side of the horizontal support member.

[0014] The guiding convex edges are bent along the extending direction of the guiding groove. The upper part of the guiding convex edges is bent and extended upward to form a first arc segment. The lower part of the first arc segment is bent and extended downward to form a U-shaped segment. The side of the U-shaped segment away from the first arc segment is bent and extended to form a second arc segment. The U-shaped segment is located at the lower end of the projection position of the horizontal support member.

[0015] Rollers are respectively rotatably installed at both ends of the downward pressure drive shaft. The rollers are respectively rotatably abutted against the lower side surfaces of the corresponding guiding convex edges. The compressible elastic member is a spiral spring.

[0016] The massage driving mechanism includes a massage arm mounting shaft rotatably mounted on the swing housing. On both sides of the massage arm mounting shaft, corresponding first massage driving wheels are eccentrically mounted. The massage arms are respectively rotatably mounted on the first massage driving wheels, and the massage arm mounting shaft is driven by a corresponding first massage driving motor.

[0017] On the first massage driving wheel, corresponding massage driving grooves are provided in an inclined shape. At positions corresponding to the massage driving grooves on the massage arm, corresponding clamping ridges are provided. After the massage arm is mounted on the first massage driving wheel, the clamping ridges can be movably clamped in the massage driving grooves.

[0018] On the swing housing on the front side of the massage arm mounting shaft, a corresponding massage arm driving shaft is rotatably mounted. On both sides of the massage arm driving shaft, corresponding second massage driving wheels are eccentrically mounted. On the second massage driving wheels, corresponding pulling plates are respectively rotatably mounted, and the pulling plates are respectively connected to the bottom sides of the corresponding massage arms through corresponding connecting rods.

[0019] One end of the swing housing is swingably connected to the moving housing through a movement center shaft.

[0020] Advantages of the present invention:

[0021] 1) When the massage mechanism of the present invention reciprocates and moves past the horizontal support member, under the drive of the vertical drive mechanism, the massage mechanism descends until its massage wheel is located on the bottom side of the horizontal support member; and when the massage mechanism reciprocates and moves away from the horizontal support member, under the drive of the vertical drive mechanism, the massage mechanism ascends until its massage wheel is located on the upper side of the horizontal support member.

[0022] Therefore, under the drive of the reciprocating drive mechanism, the massage mechanism can effectively reciprocate between a group of side support frames, and through the intervention of the vertical drive mechanism, the vertical height of the massage mechanism can be effectively controlled, so as to ensure that the massage mechanism does not interfere with the horizontal support member when reciprocating and moving past it, and the massage mechanism can effectively perform massage operations on all areas except the horizontal support member. To achieve: both maintaining the comfort of the sofa and achieving a reasonable massage effect.

[0023] 2) The vertical drive mechanism of the present invention includes a downward pressure drive shaft fixed to the end of the swing housing that is not connected to the moving housing, and a group of guide protrusions fixed to the side support frame on the lower side of the sheet support plate. The two sides of the guide protrusions are bent and extended upward respectively, and the end of the moving housing that is not connected to the swing housing is upwardly connected to a compressible elastic member for pushing the swing housing to swing upward. When the swing housing swings upward, the massage wheel rises to the upper side of the transverse support member; when the swing housing of the massage mechanism passes through the transverse support member, the downward pressure drive shaft moves downward under the drive of the guide protrusion, and the massage mechanism is pressed down until its massage wheel is located on the bottom side of the transverse support member.

[0024] Under the support of the compressible elastic member, the massage wheel of the massage mechanism can be effectively maintained on the upper side of the transverse support member, so as to ensure that it can effectively massage all areas except the transverse support member; thereafter, a guide cam is added to the lower side of the transverse support member, and a downward pressing drive shaft is adaptively added to the end of the swing shell that is not connected to the movable shell, so that each time the swing shell passes through the transverse support member, the downward pressing drive shaft can move downward under the drive of the guide cam, so that the massage mechanism is pressed down until its massage wheel is located on the bottom side of the transverse support member, ensuring that the massage mechanism does not interfere with the sheet-like support plate when it reciprocates through it.

[0025] The structure of the entire vertical driving mechanism is very simple and highly controllable, and the longitudinal drive of the massage mechanism can be achieved without the need to add a corresponding power mechanism, which has the advantages of energy saving and low consumption.

[0026] 3) Under the above premise, on the one hand, it is necessary to ensure that the massage mechanism does not interfere with the transverse support member when it reciprocates through it. Therefore, the drive shaft must be pressed down, otherwise it is easy to get stuck and locked. On the other hand, if the driving wheel descends for too long, it is easy to cause the user to not get a massage response for a long time. Therefore, in fact, the time for the drive shaft to be pressed down should not be too long. Therefore, the positional relationship between the massage structure and the transverse support member must be reasonably arranged during the use of the present invention. In order to solve the above problem, the guide convex edge is bent along the extension direction of the guide groove, and the upper part of the guide convex edge is bent upward and extended to form a first arc segment, and the lower part of the first arc segment is bent downward and extended to form a U-shaped segment. The U-shaped segment is bent and extended on the side away from the first arc segment to form a second arc segment. The U-shaped segment is located at the lower end of the projection position of the transverse support member.

[0027] Through the design of the first arc segment and the second arc segment, actually during the process of the driving shaft descending and ascending, the massage wheel is always in contact with the user's muscles. Only when passing through a small U-shaped segment, that is, when the massage wheel is located below the projection position of the horizontal support member, the massage wheel disengages from the user's back. However, since the horizontal support member is set as a short plate shape with a very short length, it is almost impossible for the user to notice, and the user's experience is hardly affected. At the same time, it plays the role of back support.

[0028] 4) Due to the short length of the above-mentioned horizontal support member, if the entire back of the user needs to be supported by the horizontal support member, the supporting force is insufficient. To solve the above problem, a longitudinal support member extending along the direction of the human spine is vertically locked to the horizontal support member. The horizontal support member and the longitudinal support member form a T-shaped auxiliary support mechanism. The horizontal support member plays a horizontal support role, and the longitudinal support member plays a longitudinal support role. Moreover, when the massage mechanism passes through the longitudinal support member, the massage wheels at both ends are exactly located on both sides of the longitudinal support member, and the longitudinal support member does not need to make way for it. While achieving the back support effect, the distance for the massage wheel to make way is short, and the support effect is better than that of a single-board support and more adaptable to the back curve of the human body.

[0034] For the convenience of those skilled in the art to understand, the embodiments will be further described in detail in conjunction with the accompanying drawings for the structure of the present invention:

[0035] Refer to Figures 1-5 , a sofa massage chair frame with a T-shaped backrest mechanism, including

[0036] The massage chair frame bracket 1 is composed of a group of side support brackets arranged side by side;

[0037] The T-shaped auxiliary support mechanism 2 includes a horizontal support member 21 fixedly connected between the upper sides of the group of side support brackets, and a longitudinal support member 22 extending along the direction of the human spine is vertically locked to the horizontal support member 21;

[0038] The massage mechanism 3 includes a massage mechanism 301, a reciprocating drive mechanism 302 for driving the massage mechanism 301 to reciprocate between the set of side support frames, and a vertical drive mechanism 303 for driving the massage mechanism 301 to move vertically between the set of side support frames. When the massage mechanism 301 reciprocates past the horizontal support member 21, under the drive of the vertical drive mechanism 303, the massage mechanism 301 descends until its massage wheel 3011 is located on the bottom side of the horizontal support member 21. When the massage mechanism 301 reciprocates away from the horizontal support member 21, under the drive of the vertical drive mechanism 303, the massage mechanism 301 ascends until its massage wheel 3011 is located on the upper side of the horizontal support member 21.

[0039] The horizontal support member 21 and the vertical support member 22 form a T-shaped auxiliary support mechanism 2. The horizontal support member 21 plays a horizontal support role, and the vertical support member 22 plays a vertical support role. While achieving a back support effect, the distance for making way for the massage wheel is short, and the support effect is better than that of a single-board support, and it is more adaptable to the back curve of the human body.

[0040] And at the end of the vertical support member 22, a corresponding horizontal support member 21 for fixing it is also provided. However, since the horizontal support member 21 on the other side is at the end and only plays a fixing role and does not need to make way, there is no need to design the guiding convex edge 3032 separately here. Among them, Figure 3 it can be clearly seen that the guiding convex edge 3032 and the side support frame are integrally provided, that is, the guiding convex edge 3032 is also formed during the process of forming the massage chair frame support 1. Therefore, the guiding convex edge 3032 does not require a separate fixing structure, and there is no so-called displacement phenomenon. The stability of the guiding convex edge 3032 is high, and the positioning degree is higher than the existing method of separate locking and fixing. The massage mechanism 301 will pass through the bottom of the horizontal support member 21 more smoothly.

[0041] It should be emphasized that the cooperation method between the horizontal support member 21 and the side support frame is that the horizontal support member 21 is locked after being snapped into the card slot in the side support frame. Through this cooperation method, the cooperation between the horizontal support member 21 and the side support frame can be made more compact. Even if the locked screw becomes loose, the horizontal support member 21 can still be clamped and fixed through the cooperation of the card slot.

[0042] In the driving mode of the reciprocating driving mechanism 302, the massage mechanism 301 can be effectively driven to reciprocate between a set of side support frames. Moreover, with the intervention of the vertical driving mechanism 303, the vertical height of the massage mechanism 301 can be effectively controlled, ensuring that the massage mechanism 301 does not interfere with the horizontal support member 21 during reciprocating movement, and enabling the massage mechanism 301 to perform massage operations on all areas except the horizontal support member 21. This achieves both maintaining the comfort of the sofa and achieving a reasonable massage effect.

[0043] At the bottom of the side support frames, corresponding guiding driving racks 4 and guiding grooves 5 are respectively provided according to height. The reciprocating driving mechanism 302 includes a moving housing 3021. The massage mechanism 301 is installed on the moving housing 3021. The front and rear ends of the moving housing 3021 are respectively connected to a driving shaft 3022 and a fixed shaft 3023. The driving shaft 3023 is driven by a corresponding reciprocating driving motor 3024. And at both ends of the driving shaft 3022, driving gears 3025 meshingly connected to the guiding driving racks 4 are fixedly connected. Both ends of the fixed shaft 3023 are slidably installed in the guiding grooves 5 respectively.

[0044] With the cooperation of the driving shaft 3022 fixedly connected with the driving gears 3025, as well as the fixed shaft 3023, the guiding driving racks 4 and the guiding grooves 5, the moving housing 3021 and the massage mechanism 301 installed on the moving housing 3021 can be stably installed for movement. Then, driven by the reciprocating driving motor 3024, the driving shaft 3022 is effectively driven to rotate, that is, the driving gears 3025 are driven to rotate, so as to effectively drive the moving housing 3021 and the massage mechanism 301 installed on the moving housing 3021 to reciprocate between the side support frames.

[0045] The massage mechanism 301 includes a swing housing 3012 whose one end is swingably connected to the moving housing 3021. One end of the swing housing 3012 is swingably connected to the moving housing 3021 through a movement center shaft 8. At the end of the swing housing 3012 not connected to the moving housing 3021, a set of corresponding massage arms 3013 are swingably connected upward. The massage wheels 3011 are respectively rotatably installed on the massage arms 3013. The massage arms 3013 are driven by a massage driving mechanism 3014 installed in the swing housing 3012.

[0046] The vertical driving mechanism 303 includes a downward pressing driving shaft 3031 fixedly installed at one end of the swinging housing 3012 that is not connected to the moving housing 3021, and a set of guiding convex edges 3032 fixedly installed on the side support frame under the lower side of the horizontal support member 21. One end of the moving housing 3021 that is not connected to the swinging housing 3012 is upwardly connected with a compressible elastic member 3033 for pushing the swinging housing 3012 to swing upward. When the swinging housing 3012 swings upward, the massage wheel 3011 rises to the upper side of the horizontal support member 21; when the swinging housing 3012 of the massage mechanism 301 passes through the horizontal support member 21, the downward pressing driving shaft 3031 moves downward under the drive of the guiding convex edges 3032, and the massage mechanism 301 is pressed downward until its massage wheel 3011 is located at the bottom side of the horizontal support member 21.

[0047] Under the supporting action of the compressible elastic member 3033, it can effectively ensure that the massage wheel 3011 of the massage mechanism 301 can be maintained on the upper side of the horizontal support member 21 to ensure that it can effectively perform massage operations on all areas except the horizontal support member 21; then, guiding convex edges 3032 are added to the lower side of the sheet-shaped support plate, and a downward pressing driving shaft 3031 is adaptively added to one end of the swinging housing 3012 that is not connected to the moving housing 3021, so that every time the swinging housing 3012 passes through the horizontal support member 21, the downward pressing driving shaft 3031 can move downward under the drive of the guiding convex edges 3032, so that the massage mechanism 301 is pressed downward until its massage wheel 3011 is located at the bottom side of the horizontal support member 21, ensuring that the massage mechanism 301 does not interfere with the horizontal support member 21 when reciprocatingly moving through it.

[0048] The structure of the entire vertical driving mechanism 303 is very simple and highly controllable, and it can realize the longitudinal drive of the massage mechanism 301 without additionally adding a corresponding power mechanism, having the advantages of energy conservation and low consumption.

[0049] The guiding convex edges 3032 are bent along the extending direction of the guiding groove 5. The upper part of the guiding convex edges 3032 is bent upward and extended with a first arc segment 30321. The lower part of the first arc segment 30321 is bent downward and extended with a U-shaped segment 30322. One side of the U-shaped segment 30322 far from the first arc segment 30321 is bent and extended with a second arc segment 30323. The U-shaped segment 30322 is located at the lower end of the projection position of the horizontal support member 21. Both ends of the downward pressing driving shaft 3031 are respectively rotatably installed with corresponding rollers 6, and the rollers 6 are respectively rotatably abutted against the lower side surfaces of the corresponding guiding convex edges 3032. The compressible elastic member 3033 adopts a spiral spring.

[0050] Through the design of the first arc segment 30321 and the second arc segment 30323, actually during the process of the drive shaft descending and ascending, the massage wheel is always in contact with the user's muscles. Only when passing through a small U-shaped segment 30322, that is, when the massage wheel is located below the projection position of the horizontal support member 21, the massage wheel disengages from the user's back. However, since the horizontal support member 21 is arranged as a short plate shape with a very short length, the user can hardly notice it, which improves the user's experience and at the same time plays a role of back support.

[0051] The massage driving mechanism 3014 includes a massage arm mounting shaft 30141 rotatably mounted on the swing housing 3012. On both sides of the massage arm mounting shaft 30141, corresponding first massage driving wheels 30142 are eccentrically mounted. The massage arms 3013 are respectively rotatably mounted on the first massage driving wheels 30142, and the massage arm mounting shaft 30141 is driven by a corresponding first massage driving motor 30143.

[0052] On the first massage driving wheel 30142, corresponding massage driving grooves 7 are provided in an inclined shape. At positions corresponding to the massage driving grooves 7 on the massage arms 3013, corresponding clamping protrusions are provided. After the massage arms 3013 are mounted on the first massage driving wheels 30142, the clamping protrusions can be movably clamped in the massage driving grooves 7.

[0053] On the swing housing 3012 in front of the massage arm mounting shaft 30141, a corresponding massage arm driving shaft 30144 is rotatably mounted. On both sides of the massage arm driving shaft 30144, corresponding second massage driving wheels 30145 are eccentrically mounted. On the second massage driving wheels 30145, corresponding pulling plates 30146 are respectively rotatably mounted, and the pulling plates 30146 are respectively connected to the bottom sides of the corresponding massage arms 3013 through corresponding connecting rods 30147.

[0054] Driven by the first massage driving motor 30143 of the massage driving mechanism 3014 and the second massage driving wheels 30145, the massage arms 3013 can be effectively driven to swing in different directions, thereby driving the massage wheel to produce a massage effect on the human body. The overall structure and driving method of the massage driving mechanism 3014 are prior arts and will not be elaborated here.

[0055] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
