Description

A sofa massage chair frame whose movement automatically avoids the human body technical field

The present invention relates to a sofa massage chair frame whose movement automatically avoids the human body, which not only has the comfort of a sofa, but also has sufficient massage functions.

Background technique

A sofa is a kind of upholstered furniture. In order to ensure the support of the backrest of the sofa, the backrest of the existing sofa is generally equipped with a corresponding backrest, and then the cushion is installed on the backrest. Under the obstruction of the back-to-board, the existing sofas cannot be installed with massage mechanisms. Even if there are a small number of sofas with massage mechanisms, they can only be partially fixed on the positions where the back-to-back is not provided with the back-to-board, and a reasonable massage effect cannot be achieved at all.

Even some existing massage structures that use back support often use a whole piece of support structure that fits most of the back of the human body to directly support the user's entire back or a wide range of back to achieve the effect of support. However, if this support structure is used, the massage core needs to sink for a long time to pass through the back support structure. The blank period of the user's massage period is longer, and the overall experience is affected.

Moreover, due to the large area of the back of the human body, the existing support is all about setting the support structure on the position of the back, but there is often no adaptability in some structures for massaging the head, waist, and buttocks, and the effect of single-point support is poor.

Therefore, on the basis of retaining the sofa's need for body support and ensuring its comfort, it is the research purpose of this invention to design a sofa massage chair frame that can effectively set up a mobile massage mechanism, thereby maintaining the comfort of the sofa and achieving a reasonable massage effect.

The massage wheels are respectively rotatably mounted on the massage arms. The massage arms are driven by the massage driving mechanism installed in the swing housing. One end of the swing housing is swingably connected to the moving housing through a central axis of motion.

As a further improvement, the vertical drive mechanism includes a downward drive shaft that is fixed at one end of the swing housing that is not connected to the moving housing. The end of the moving housing that is not connected to the swing housing is connected upward with a compressible elastic member for pushing the swing housing up. The massage wheel is located on the bottom side of the supporting member, and the two ends of the pressing drive shaft are rotatably installed with corresponding rollers, and the rollers are respectively rotatably abutted against the lower side of the corresponding guide ledge, and the compressible elastic member adopts a coil spring.

As a further improvement, the support member is a set of support rods arranged at intervals, and the support rods are arranged in a snake shape, and the two ends of the support rods are respectively fixed between the group of side support frames, the guide convex edge is arranged in a W shape, and the orthographic projection position of the support rod corresponds to the lowest end of the guide convex edge.

As a further improvement, the support member is a sheet-shaped support plate fixed between the upper sides of the group of side support frames. The lower side of the guide lip is bent in an arc shape. The upper part of the guide lip is bent upwards and provided with a first bending section. The upper part of the first bending section is bent upwards and provided with a second bending section.

As a further improvement, the support includes a transverse portion fixed between the upper sides of the group of side support frames, and a longitudinal portion extending from the head of the human body to the buttocks. The guide protrusion is curved along the direction along which the guide groove extends. The upper part of the guide protrusion is curved upward to extend a first arc segment, and the lower part of the first arc segment is curved downward to extend a U-shaped segment.

As a further improvement, the massage driving mechanism includes a massage arm installation shaft rotatably mounted on the swing housing. Corresponding first massage drive wheels are installed on both sides of the massage arm installation shaft in an eccentric state. The massage arms are respectively rotatably mounted on the first massage drive wheels, and the massage arm installation shaft is driven by the corresponding first massage drive motor.

As a further improvement, the first massage drive wheel is provided with a corresponding massage drive groove in an inclined shape, and the massage arm is provided with a corresponding snap-in convex edge at a position corresponding to the massage drive groove. After the massage arm is installed on the first massage drive wheel, the snap-in convex edge can be movably snapped into the massage drive groove.

As a further improvement, the swing housing on the front side of the massage arm installation shaft is rotatably mounted with a corresponding massage arm drive shaft, and the two sides of the massage arm drive shaft are respectively mounted with corresponding second massage drive wheels in an eccentric state. The second massage drive wheels are respectively rotatably mounted with corresponding pulling plates, and the pulling plates are respectively connected to the bottom side of the corresponding massage arms through corresponding connecting rods.

The beneficial effects of the present invention are:

the 1) When the massage mechanism of the present invention reciprocates through the support mechanism, driven by the vertical drive mechanism, the massage mechanism descends until its massage wheels are located on the bottom side of the support mechanism; and when the massage mechanism reciprocates away from the support mechanism, driven by the vertical drive mechanism, the massage mechanism rises until its massage wheels are located on the upper side of the support mechanism.

Therefore, driven by the reciprocating drive mechanism, the massage mechanism can effectively move back and forth 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 support mechanism when it reciprocates, and the massage mechanism can perform massage operations on all areas except the support mechanism. In order to achieve: not only can maintain the comfort of the sofa, but also can achieve a reasonable massage effect.

2) The inventive vertical drive mechanism includes a downward drive shaft that is fixed at the end of the swing housing that is not connected to the moving housing, and a set of guide flanges that are fixed at the side support frame on the lower side of the support rod. The end of the moving housing that is not connected to the swing housing is connected upward with a compressible elastic member for pushing the swing housing up. When the oscillating housing swings up, the massage wheels rise to the upper side of the support bar; when the oscillating housing of the massage mechanism passes the support bar, the pressing drive shaft moves down under the drive of the guide convex edge, and the massage mechanism is pressed down until its massage wheels are located on the bottom side of the support bar.

Under the support of the compressible elastic member, it can effectively ensure that the massage wheel of the massage mechanism can be maintained on the upper side of the support member, so as to ensure that it can effectively perform massage operations on all areas except for it; then, the guide convex edge is added on the lower side of the support member, and the push-down driving shaft is adaptively added at the end of the swing housing that is not connected to the moving housing, so that every time the swing housing passes by, the push-down drive shaft can be driven down by the guide flange, so that the massage mechanism is pressed down until the massage wheel is on the support underside of the support to ensure that the massaging mechanism does not interfere with the support as it reciprocates across it.

The structure of the entire vertical drive mechanism is very simple and highly controllable, and the vertical drive of the massage mechanism can be realized without adding an additional corresponding power mechanism, which has the advantages of energy saving and low consumption.

3) In one embodiment of the present invention, the support member of the present invention is a set of support rods arranged at intervals. The support rods are arranged in the shape of a snake, and the two ends of the support rods are respectively fixed between the group of side support frames. Through the arrangement of a group of support rods arranged in the shape of a snake, it can effectively ensure the support effect on the back of the human body under a very small space occupation. Then, under the intervention of the guide convex edge that is arranged in a W shape, it can effectively ensure that when the swing housing passes through the support rod, the pressing drive shaft can move down under the drive of the guide flange, so that the massage mechanism is pressed down until its massage wheel is located at the bottom side of the support rod, ensuring that the massage mechanism does not interfere with it when it reciprocates through the support rod; While ensuring the back support effect, the massage effect is further greatly improved.

4) In another embodiment of the present invention, the support member is a sheet-shaped support plate fixed between the upper sides of the set of side support frames. Since different body areas have different massage fitting requirements, the height and position of the massage wheel need to be kept constant, so the pressing drive shaft should not be pressed down too early; however, on the other hand, it is also necessary to ensure that the massage mechanism does not interfere with it when it reciprocates through the sheet-shaped support plate. In order to solve the above-mentioned technical problem, the present invention bends the lower side of the guide convex edge in an arc shape, then, the upper part of the guide convex edge is bent upwards to provide a first bending section, and the upper part of the first bending section is bent upwards to provide a second bending section, and the inclination angle of the second bending section is controlled to be greater than the inclination angle of the second bending section.

Through the setting of the second bending section with a large inclination angle, it can effectively and quickly form a downward pressure on the pressing driving shaft, so that the swinging shell can quickly swing down, thereby shortening the reciprocating pressing stroke of the pressing driving shaft, which can not only maintain a sufficient massage effect, but also ensure that the massage mechanism does not interfere with the sheet support plate; and then use the first bending section with a small inclination angle to effectively form a buffering downward pressure on the pressing driving shaft that is pressed down quickly, so as to prevent excessive clamping force of the pressing driving shaft caused by the rapid pressing stroke, thus effectively ensuring Practical effect of the present invention.

5) In yet another embodiment of the present invention, the support includes a transverse portion fixed between the upper sides of the set of side support frames, and a longitudinal portion extending from the head of the human body to the buttocks. On the one hand, it is necessary to ensure that the massage mechanism does not interfere with it when reciprocatingly moving past the support. Therefore, the drive shaft must be pressed down, otherwise it is easy to be locked. During the process, the positional relationship between the massage structure and the support must be reasonably arranged. In order to solve the above-mentioned problems, the guide protrusion is bent along the extending direction of the guide groove, the upper part of the guide protrusion bends upwards and extends with a first arc segment, the lower part of the first arc segment bends downwards and extends with a U-shaped segment, and the side of the U-shaped segment away from the first arc segment bends and extends with a second arc segment, and the U-shaped segment is located at the lower end of the projected position of the lateral portion.

Through the design of the first arc segment and the second arc segment, in fact, during the process of lowering and raising the drive shaft, the massage wheel is always in contact with the user's muscles. Only when the massage wheel passes through a short U-shaped segment, that is, when the massage wheel is located under the projection position of the horizontal support, does the massage wheel detach from the user's back. However, since the horizontal part is set in the shape of a short plate with an extremely short length, the user can hardly find it.

6) Due to the short length of the above-mentioned horizontal part, if the whole body of the user needs to be supported by the horizontal part, the supporting strength is insufficient. In order to solve the above-mentioned problem, the supporting member includes a horizontal part fixed between the upper sides of the set of side support frames, and a longitudinal part extending from the human head to the buttocks. The horizontal part and the longitudinal part form a T-shaped auxiliary support mechanism. On both sides, the vertical part does not need to give way to it. While playing the back support effect, the distance for the massage wheel to give way is short, and the support effect is better than that of the veneer support, and it is more suitable for the body curve of the human body.

Referring to Figures 1-8, a sofa massage chair frame whose movement automatically avoids the human body comprises: a massage chair frame support 1, which is composed of at least one group of side support frames arranged side by side; a support mechanism, including a support member fixedly connected between the group of side support frames for supporting the body; a massage movement 3, including a massage mechanism 301, a reciprocating drive mechanism 302 for driving the massage mechanism 301 to reciprocate between the group of side support frames, and a reciprocating drive mechanism 302 for driving the massage mechanism 301 to move vertically between the group of side support frames Vertical driving mechanism 303, and a set of guide ledges on the side support frame on the lower side of the support. When the massage mechanism 301 moves back and forth through the support, under the drive of the vertical drive mechanism 303, the massage mechanism 301 descends along the guide ledge until its massage wheel 3011 is located on the bottom side of the support. Its massage wheel 3011 is located on the upper side of the support.

Wherein, an inner cavity for the massage movement 3 is formed between the massage chair frame brackets 1, and the support mechanism supports the user's body. With the above-mentioned structure, when there is no external obstruction, such as bones, etc., the massage movement 3 follows the normal movement track form, and when encountering a position that needs to be avoided, since the support mechanism is arranged above the position, and the corresponding support mechanism is provided with a guide convex edge, the massage mechanism 301 in the massage movement 3 changes its movement trajectory along the guide convex edge, avoiding the support mechanism, so that the massage mechanism 301 It forms an avoidance effect on the user's bones and other parts, and achieves the switching effect between the normal trajectory and the avoidance trajectory. While performing a massage function for the user, it can avoid the user's bones and other parts, and improve the massage effect.

Wherein, the support mechanism can be an elastic support, a rigid support, a fixed support, or a movable support, and the massage movement 3 can also be a 3D massage movement, which is driven by a motor to realize the massage head avoiding the support mechanism.

In order to promote the massage movement 3 to walk along the normal track, the bottom of the side support frame is respectively provided with corresponding guide drive racks 4 and guide grooves 5 according to the height, and the reciprocating drive mechanism 302 matched with it includes a moving housing 3021, and the massage mechanism 301 is installed on the moving housing 3021. 4 is driven, and the two ends of the drive shaft 3022 are fixedly connected with the drive gear 3025 meshingly connected to the guide drive rack 4, respectively, and the two ends of the fixed shaft 3023 are respectively movable and installed in the guide groove 5.

The massage wheels 3011 are respectively rotatably installed on the 3013, and the massage arms 3013 are driven by the massage driving mechanism 3014 installed in the swing housing 3012, and since the massage mechanism 301 needs to swing to give way when passing through the support mechanism, one end of the swing housing 3012 is swingably connected to the moving housing 3021 through the movement central shaft 8.

The specific structure of the part that realizes the swinging up and down of the swinging housing 3012 is as follows: the vertical drive mechanism 303 includes a downward-pressing drive shaft 3031 that is fixed at the end of the swinging housing 3012 that is not connected to the moving housing 3021, and the 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 upwards. When the swinging housing 3012 swings up, the massage wheel 3011 rises to the upper side of the support member. When the swing housing 3012 of the massage mechanism 301 passes the support member, the pressing drive shaft 3031 moves down under the drive of the guide flange. Part 3033 adopts a helical spring, and because the roller 6 cooperates with the guide convex edge, so when the entire massage mechanism 301 touches the support mechanism, the massage wheel 3011 will be squeezed by the support mechanism, thereby exerting pressure on the bottom, squeezing the compressible elastic member 3033, allowing the massage wheel 3011 to pass through the support mechanism in an avoidable manner, and after passing the path corresponding to the support mechanism, the compressible elastic member 3033 provides reset power, so that the massage core 3 returns to the normal path along the guide convex edge. , the compressible elastic member 3033 is a coil spring, and in other embodiments, the compressible elastic member 3033 can be sponge or other elastic materials, or, in some embodiments, it can be controlled by a lifting structure such as a hydraulic cylinder.

Wherein, the massage driving mechanism 3014 includes a massage arm installation shaft 30141 rotatably installed on the swing housing 3012. The two sides of the massage arm installation shaft 30141 are respectively eccentrically installed with corresponding first massage driving wheels 30142. The massage arms 3013 are respectively rotatably installed on the first massage driving wheels 30142. The massage arm installation shafts 30141 are driven by corresponding first massage driving motors 30143.

Wherein, the first massage driving wheel 30142 is provided with a corresponding massage driving groove 7 in an inclined shape, and the massage arm 3013 is provided with a corresponding engaging convex edge at a position corresponding to the massage driving groove 7. After the massage arm 3013 is installed on the first massage driving wheel 30142, the engaging convex edge can be movably engaged in the massage driving groove 7.

Wherein, the swing housing 3012 on the front side of the massage arm installation shaft 30141 is rotatably mounted with a corresponding massage arm drive shaft 30144, and the two sides of the massage arm drive shaft 30144 are respectively eccentrically installed with corresponding second massage drive wheels 30145, and the corresponding pull plates 30146 are respectively rotatably mounted on the second massage drive wheels 30145, and the pull plates 30146 are respectively connected to corresponding massage arms 3 through corresponding connecting rods 30147 013 underside.

The overall structure and driving method of the massage driving mechanism 3014 are prior art, and will not be repeated here.

In the above description, the support mechanism is a support for supporting the body, but in fact, the support can have various styles. Correspondingly, due to the different styles of the support, the guide flanges also need to be set in different styles, so that the massage movement 3 can pass through the support in the shortest time when passing the guide flange. At the same time, according to the various physical characteristics of the customer, such as height, weight, shoulder width and other ratios, the positions of the support and the guide flange can be specifically set, which are specifically divided into the following three embodiments:

It should be noted that the above-mentioned support mechanism and guide flange are described in a high-level manner, and there is no specific reference structure in the figure.

Embodiment one

Among them, the position of the support rod A can be set on the user's head, shoulders, waist, buttocks, etc., and the supporting area is small, and because the support rods A are set as a group, the first guide convex edge 3032A is W-shaped. It can be deduced that if the support rod A is designed as a single piece, the first guide convex edge 3032A can be set in a V-shaped structure. Through the setting of a group of support rods A arranged in a snake shape, it can effectively ensure the support effect on the back of the human body with a very small space occupation. Then, with the intervention of the first guide convex edge 3032A arranged in a W shape, it can be effectively ensured that when the swing housing 3012 passes the support rod, the pressing drive shaft 3031 can move down under the drive of the first guide convex edge 3032A, so that the massage mechanism 301 is pressed down until the massage wheel 3011 is located at the bottom side of the support rod, ensuring that the massage mechanism 301 does not interfere with it when reciprocatingly moving through the support rod.

Embodiment two

Referring to Fig. 2, in this embodiment, the support member is a sheet-shaped support plate B fixedly connected between the upper sides of the group of side support frames, the guiding convex edge is a second guiding convex edge 3032B, and the lower side of the second guiding convex edge 3032B is curved and arranged in an arc shape, and the upper part of the second guiding convex edge 3032B is bent upwardly and is provided with a first bending section 30321B, and the upper part of the first bending section 30321B is bent upwardly and is provided with a second bending section 30 322B, the inclination angle of the second bending section 30322B is greater than the inclination angle of the first bending section 30321B, and the opening of the guide protrusion 3032B faces the sheet support plate B.

Among them, the position of the sheet support plate B can be set on the user's head, shoulders, waist, buttocks, etc. for support. The supporting area is large. The second guide convex edge 3032B can effectively and quickly form a downward pressure on the downward pressure drive shaft 3031 through the setting of the second bending section 30322B with a large inclination angle, so that the swing housing 3012 can quickly swing down, thereby shortening the reciprocating downward pressure stroke of the downward pressure drive shaft 3031, which can not only maintain a sufficient massage effect, but also ensure the massage mechanism 301 does not interfere with the sheet-shaped support plate B; and then through the first bending section 30321B with a small inclination angle, it can effectively form a buffered downward pressure on the rapidly depressed downward driving shaft 3031, so as to prevent the rapid downward stroke from causing excessive clamping force on the downward pressing driving shaft 3031.

Embodiment three

Referring to Fig. 3, in this embodiment, the support member includes a transverse portion C1 fixedly connected between the upper sides of the group of side support frames, and a longitudinal portion C2 extending from the head of the human body to the buttocks. The guide convex edge is a third guide convex edge 3032C. The lower part of the U-shaped section 30322C is bent and extended downward, and the side of the U-shaped section 30322C away from the first arc section 30321C is bent and extended to form a second arc section 30323C, and the U-shaped section 30322C is located at the lower end of the projected position of the transverse portion C1.

The horizontal part C1 can also be set on the user's shoulders, waist, etc. At the same time, it can also be set in reverse, and the horizontal part C1 can be set at the buttocks, and then the vertical part C2 can be extended in the opposite direction.

Through the design of the first arc segment 30321C and the second arc segment 30323C, in fact, the massage wheel is still in contact with the user's muscles during the process of lowering and lifting of the drive shaft. Only when the massage wheel passes through a short U-shaped segment 30322C, that is, when the massage wheel is located under the projection position of the lateral support 21, does the massage wheel detach from the user's back. However, since the lateral support 21 is set as a short plate with an extremely short length, the user can hardly find it, which improves the user's experience and improves user experience. It also acts as a back support.

Through the above three embodiments, it can be concluded that the supporting mechanism can be set on different body parts of the user to support different parts of the user's body. Correspondingly, different guiding convex edges can also be set, and different supporting mechanisms, guiding convex edges and installation positions can be combined to obtain a variety of installation solutions, which can be customized according to the needs of users.
