Description

Technical Field

[0001] The present application relates to the technical field of massage equipment, and in particular to a sofa frame and a massage sofa. Background Art

[0002] A massage sofa usually has a massage mechanism on the backrest to massage the user's waist and back. However, after the massage is completed, the massage mechanism protrudes from the backrest surface, which will cause a bruising sensation on the user's waist and back. As a result, the massage sofa cannot be used as an ordinary sofa after the massage is completed, and can only be used for a short period of time during massage, resulting in a low utilization rate of the massage sofa.

[0003] In order to prevent the massage mechanism from protruding from the backrest surface after the massage is finished and causing a backache to the user's waist and back, in the prior art, an airbag is covered on the surface of the massage mechanism. After the massage is finished, the airbag is inflated to isolate the massage head and the waist and back to reduce the backache. During the massage, the gas in the airbag is discharged so that the force of the massage mechanism acts on the waist and back through the airbag. Since the airbag is between the massage mechanism and the waist and back during the massage, the airbag itself has a certain thickness, which will weaken the massage effect and reduce the user experience. In addition, since the massage mechanism set on the sofa backrest has a certain volume and thickness, during the massage, the gas in the airbag is discharged, and the waist and back are supported at a suitable support height. After the massage is finished, in order to prevent the backache, the airbag is inflated and expanded. The waist and back support height is the thickness of the massage mechanism itself plus the expansion height of the airbag, which will cause the backrest support height to be too high, causing discomfort to the user. Summary of the invention

[0004] The present application provides a sofa frame, and the present application also provides a massage sofa.

[0005] In a first aspect, the present application provides a sofa frame, which includes a cushion frame, a backrest frame, a guide rail mechanism, a massage mechanism, a driving mechanism and a support mechanism. The backrest frame is connected to the cushion frame, and the cushion frame and the backrest frame jointly define a seat space. The massage mechanism is movably connected to the guide rail mechanism. The driving mechanism is connected between the massage mechanism and the guide rail mechanism, and the driving mechanism is used to drive the massage mechanism to move along the path defined by the guide rail mechanism so that the massage mechanism can be located on the cushion frame or the backrest frame. The support mechanism is movably arranged on the backrest frame, and the support mechanism includes a support member and a support driving member connected to the support member, and the support member is driven by the support driving member to switch between a first position and a second position.

[0006] In a second aspect, the present application further provides a massage sofa, which comprises a sofa body and the sofa frame, wherein the sofa frame is arranged inside the sofa body.

[0007] In the sofa frame provided by the present application, since the sofa frame includes a cushion frame, a backrest frame, a guide rail mechanism, a massage mechanism, a driving mechanism and a supporting mechanism, and the supporting mechanism includes a supporting member and a supporting driving member. When massage is needed, the massage mechanism moves along the guide rail mechanism to the position of the backrest frame, and at this time, the supporting driving member drives the supporting member to move to the first position of the massage mechanism away from the side of the seat space to give way to the massage mechanism; after the massage is completed, the massage mechanism moves along the guide rail mechanism to the position of the cushion frame, and at this time, the supporting driving member drives the supporting member to move to the second position closer to the seat space relative to the first position to support the user's waist and back. Through the above-mentioned setting, the movable massage mechanism and the supporting mechanism work together, which can not only ensure that the massage mechanism is in direct contact with the user's waist and back during the massage process, thereby improving the massage effect, but also enable the supporting mechanism to fully support the user's waist and back after the massage, thereby improving the user's comfort. Therefore, the above-mentioned sofa frame has the beneficial effects of good massage effect and good user experience. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0016] In the description of the present application, it should be understood that terms such as "length", "width", "thickness", "up", "down", "front", "back", "left", "right", and "inside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only used to simplify the description of the present application and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present application.

[0017] In the description of the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0018] In addition, unless otherwise expressly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be internal communication between two elements, or it can be only surface contact. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0019] If certain words are used in the specification and claims to refer to specific components, those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use differences in names as a way to distinguish components, but use differences in components' functions as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to"; "substantially" means that those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0020] See also Figure 1 The embodiment of the present application provides a sofa frame 100, which is suitable for a massage sofa 200 and can serve as a skeleton of the massage sofa 200 to provide support and massage.

[0021] The sofa frame 100 includes a cushion frame 10, a backrest frame 20, a guide rail mechanism 30, a massage mechanism 40, a drive mechanism 50 and a support mechanism 60. The cushion frame 10 and the backrest frame 20 together constitute the main frame of the sofa frame 100. The cushion frame 10 is used to support the user's buttocks and thighs, and the backrest frame 20 is used to support the user's waist and back. The backrest frame 20 is connected to the cushion frame 10, and the two together define a seat space 70. The above-mentioned "seat space 70" can be understood as: when the user sits on the sofa, the user's torso is roughly located. The range of the seat space 70 is roughly: when the sofa frame 100 is in normal use, the vertically upward area of ​​the cushion frame 10 overlaps with the area of ​​the backrest frame 20 facing the side of the cushion frame 10.

[0022] The guide rail mechanism 30 is connected to the cushion frame 10, and the guide rail mechanism 30 extends from the cushion frame 10 to the backrest frame 20. The guide rail mechanism 30 is used to cooperate with the massage mechanism 40 to achieve movement, and can limit the movement path and range of the massage mechanism 40. The massage mechanism 40 is movably connected to the guide rail mechanism 30, and the massage mechanism 40 can contact the user's torso and massage the user. The driving mechanism 50 is connected between the massage mechanism 40 and the guide rail mechanism 30. The driving mechanism 50 is used to drive the massage mechanism 40 to move along the path defined by the guide rail mechanism 30, so that the massage mechanism 40 can be located at the cushion frame 10 or at the backrest frame 20, that is, the massage mechanism 40 can be driven by the driving mechanism 50 to move along the guide rail mechanism 30 to the position of the cushion frame 10, or to the position of the backrest frame 20. The support mechanism 60 is movably arranged on the backrest frame 20, and the support mechanism 60 includes a support member 601 and a support driving member 602 connected to the support member 601. The support member 601 is driven by the support driving member 602 to switch between the first position and the second position. The above-mentioned "first position and second position" should be understood as: two different positions of the support member 601 during use. Specifically, when the massage mechanism 40 is located at the backrest frame 20, the support member 601 is in the first position, and the support member 601 is located on the side of the massage mechanism 40 away from the seat space 70 to make way for the massage mechanism 40. When the massage mechanism 40 is located at the cushion frame 10, the support member 601 is in the second position, and the second position is closer to the seat space 70 than the first position. The first position and the second position correspond to the positions of the support member 601 in two different use states. In the drawings of the specification of this embodiment, the support member 601 is always in the second position. The structural state diagram of the support member 601 in the first position is easier to understand, so it is not shown.

[0023] Through the above arrangement, when massage is needed, the massage mechanism 40 moves along the guide rail mechanism 30 to the position of the backrest frame 20, and the support drive member 602 drives the support member 601 to move to the first position of the massage mechanism 40 away from the seat space 70 to give way to the massage mechanism 40; after the massage is finished, the massage mechanism 40 moves along the guide rail mechanism 30 to the position of the cushion frame 10, and the support drive member 602 drives the support member 601 to move to the second position closer to the seat space 70 relative to the first position to support the user's waist and back. Since the massage mechanism 40 is not at the position of the backrest frame 20, it will not cause the support height of the backrest frame 20 to be too high. Through the above arrangement, the movable massage mechanism 40 and the support mechanism 60 work together, which can not only ensure that the massage mechanism 40 is in direct contact with the user's waist and back during the massage process, thereby improving the massage effect, but also enable the support mechanism 60 to fully support the user's waist and back after the massage, thereby improving the user's comfort.

[0024] In some embodiments, when the massage mechanism 40 is located on the backrest frame 20 and the support member 601 is in the first position, the support member 601 is pressed against the side of the massage mechanism 40 away from the seat space 70, and the support driving member 602 can drive the support member 601 to move toward the direction close to the seat space 70 to push the massage mechanism 40 close to the seat space 70.

[0025] Through the above arrangement, when the massage mechanism 40 is in the position of the backrest frame 20 and the support member 601 is in the first position, the support drive member 602 can push the massage mechanism 40 so that the massage mechanism 40 protrudes from the surface of the sofa backrest, thereby enhancing the massage effect. On the contrary, if the massage effect is to be weakened, the support drive member 602 is controlled to drive the massage mechanism 40 to retract.

[0026] Please continue reading Figure 1 In some embodiments, the guide rail mechanism 30 is a flexible guide rail. The above-mentioned "flexible guide rail" should be understood as being able to deform within a certain degree, but it is not necessarily limited to being made of flexible materials. For example, the "flexible guide rail" can be composed of multiple guide rail units connected in succession, and the multiple guide rail units can move relative to each other (for example, rotate relative to each other at a certain angle) to facilitate deformation and thus change the extension direction of the entire guide rail; for another example, the "flexible guide rail" as a whole can be made of a flexible material (such as rubber) that can undergo elastic deformation, so that the extension direction of the entire guide rail can be changed when deformed. Therefore, the guide rail mechanism 30 can be laid from the seat cushion frame 10 to the backrest frame 20, and even if the angle between the seat cushion frame 10 and the backrest frame 20 changes, the extension direction of the guide rail mechanism 30 can also change accordingly.

[0027] The sofa frame 100 also includes a movable connection mechanism 80, through which the cushion frame 10 and the backrest frame 20 are movably connected. The backrest frame 20 can change the angle between the cushion frame 10 and the cushion frame 10 under the drive of the movable connection mechanism 80. When the backrest frame 20 moves relative to the cushion frame 10, the support member 601 and the guide rail mechanism 30 move synchronously with the backrest. As a specific example, in the drawings of the specification of this embodiment, the movable connection mechanism 80 includes a motor (not shown in the figure), a first gear 801 and a second gear 802. The motor is connected to the cushion frame 10. The first gear 801 is rotatably connected to the cushion frame 10 and is fixedly connected to the output shaft of the motor. The second gear 802 is fixedly connected to the backrest frame 20. The first gear 801 is meshed with the second gear 802. When the motor drives the first gear 801 to rotate, it will drive the second gear 802 to rotate. The rotation of the second gear 802 drives the backrest frame 20 to rotate relative to the cushion frame 10, so as to change the angle between the backrest frame 20 and the cushion frame 10. In other embodiments, the movable connection mechanism 80 may also be other types of connection mechanisms, for example, a rack that can reciprocate along a horizontal straight line may be provided on the seat cushion frame 10, and a gear meshing with the rack may be fixedly provided on the backrest frame 20, and the horizontal movement of the rack drives the gear to rotate, thereby driving the backrest frame 20 to rotate. The specific structure of the movable connection mechanism 80 is not limited, and it only needs to be able to realize the function of rotating the backrest frame 20 relative to the seat cushion frame 10.

[0028] See also Figure 2 In some embodiments, the support driving member 602 is disposed on the backrest frame 20, and the support mechanism 60 further includes a telescopic frame 603 disposed between the support member 601 and the support driving member 602. Through the above arrangement, the support driving member 602 can drive the telescopic frame 603 to telescopically move, and the telescopic movement of the telescopic frame 603 will drive the support member 601 to move, thereby realizing the position switching of the support member 601.

[0029] As a specific example, in Figure 2In the illustrated embodiment, the support driving member 602 is an electric push rod, and the telescopic frame 603 includes at least two folding frames 604 arranged at intervals, and the folding frame 604 includes a first support rod 6041 and a second support rod 6042, which are arranged crosswise and rotatably connected to each other, and the first support rod 6041 and the second support rod 6042 are generally in an "X" shape as a whole. The two ends of the first support rod 6041 are movably connected to the support member 601 and the backrest frame 20, respectively, and the two ends of the second support rod 6042 are movably connected to the support member 601 and the backrest frame 20, respectively, and the support driving member 602 is connected to at least one of the first support rod 6041 and the second support rod 6042 to drive the telescopic frame 603 to telescope and fold. Specifically in this embodiment, the two ends of the first support rod 6041 are respectively rotatably and slidably connected to the support member 601 and the backrest frame 20 (the support member 601 and the backrest frame 20 may be provided with guide grooves for limiting the sliding direction), and the two ends of the second support rod 6042 are respectively rotatably and slidably connected to the support member 601 and the backrest frame 200 (the support member 601 and the backrest frame 20 may be provided with guide grooves for limiting the sliding direction), so as to meet the requirements of the telescopic freedom of the telescopic frame 603 and ensure the stability of the structure. The first support rod 6041 and the second support rod 6042 are rotatably connected to form a group of telescopic support structures, and multiple such telescopic support structures may be provided, and the multiple telescopic support structures may be arranged in parallel in sequence, thereby improving the structural stability and supporting strength of the telescopic bracket 603.

[0030] Through the above arrangement, the support driving member 602 can drive the folding bracket 604 to fold by telescoping. When the folding bracket 604 is folded, the two ends of the first support rod 6041 and the two ends of the second support rod 6042 are respectively close to each other, thereby driving the support member 601 to move away from the seat space 70, so that the massage mechanism 40 moves to the position of the backrest frame 20 for massage; when the massage mechanism 40 moves to the position of the cushion frame 10, the folding bracket 604 can be opened, at which time the two ends of the first support rod 6041 and the two ends of the second support rod 6042 are respectively far away from each other, thereby driving the support member 601 to move towards the seat space 70, so that the support frame supports the waist and back of the user. Further, the cross-arranged folding brackets 604 can make the movement of the support member 601 more stable, and when the folding brackets 604 are folded, the support member 601 is almost completely attached to the bottom of the backrest frame 20 (i.e., the side away from the seat space 70), which can make room for a larger space for accommodating the massage mechanism 40. Furthermore, since the electric push rod has the characteristic of linear telescopic adjustment, the movement of the support member 601 also has linear characteristics. Different users can linearly adjust the position of the support member 601 according to their own usage habits, thereby obtaining different support heights to meet diverse usage requirements.

[0031] Please continue reading Figure 2 In some embodiments, the support member 601 is provided with a first movable groove 6011, and the backrest frame 20 is provided with a second movable groove 201. The first movable groove 6011 extends substantially along the extension direction of the support member 601, and the extension direction of the support member 601 is substantially the same as the length direction of the support member 601, and the extension direction of the second movable groove 201 is substantially the same as the extension direction of the first movable groove 6011. One end of the first support rod 6041 is movably connected to the first movable groove 6011, and the other end is rotatably connected to the backrest frame 20. One end of the second support rod 6042 is movably connected to the second movable groove 201, and the other end is rotatably connected to the support member 601. For example, two ends of the first support rod 6041 can be provided with a clamping block, and the two clamping blocks are slidably connected to the first movable groove 6011 and the second movable groove 201, respectively, to achieve connection. When the folding bracket 604 is opened or folded, the card block can slide in the first movable groove 6011 and the second movable groove 201, so that the folding bracket 604 can complete the corresponding action. The first movable groove 6011 and the second movable groove 201 can provide movable space for the folding bracket 604 when it is opened and folded, so that the folding bracket 604 can be opened and closed better.

[0032] Please also see Figure 3 and Figure 4 In some embodiments, the driving mechanism 50 includes a driving motor 501 and a driving gear 502. The driving motor 501 is disposed on the massage mechanism 40. For example, the driving motor 501 can be disposed on the side of the massage mechanism 40 away from the seat space 70. The driving motor 501 and the driving gear 502 are connected in a transmission manner. The guide rail mechanism 30 is provided with convex teeth 301 in parallel. The convex teeth 301 are meshed with the driving gear 502. The driving motor 501 drives the driving gear 502 to rotate. When the driving gear 502 rotates, it rolls on the guide rail mechanism 30 by meshing with the convex teeth 301, thereby driving the massage mechanism 40 to move along the guide rail mechanism 30. The above-mentioned "convex teeth 301" should be understood as a component with a continuous tooth structure (such as a rack, etc.), and the extension direction of the tooth structure is substantially the same as the extension direction of the guide rail mechanism 30. It should be noted that the above detailed description of the driving mechanism 50 is only a specific example, and not a limitation on the structure of the driving mechanism 50. In other embodiments, the driving mechanism 50 may also be a mechanism of other types, as long as it can realize the function of driving the massage mechanism 40 to move along the guide rail mechanism 30. For example, the driving gear 502 may be replaced by a roller structure, which may not have convex teeth, but relies on the friction between it and the guide rail to roll on the guide rail, thereby driving the massage mechanism 40 to move along the guide rail.

[0033] Through the above arrangement, when the driving motor 501 is started, the driving gear 502 rotates under the drive of the driving motor 501. Since the driving gear 502 is engaged with the convex tooth 301, and the convex tooth 301 is arranged side by side with the guide rail mechanism 30, the driving gear 502 will drive the massage mechanism 40 and the driving motor 501 to move along the extension direction of the guide rail mechanism 30, and by controlling the forward and reverse rotation of the driving motor 501, the moving direction of the massage mechanism 40 can be changed to realize the back and forth movement of the massage mechanism 40 between the seat cushion frame 10 and the backrest frame 20.

[0034] See also Figure 4 , further, in the illustrated embodiment, the driving mechanism 50 also includes a transmission gear 504 and a worm 505, the worm 505 is fixedly connected to the output shaft of the driving motor 501, the transmission gear 504 is coaxially arranged with the driving gear 502, and the transmission gear 504 is meshed with the worm 505. Through the above arrangement, when the driving motor 501 is started, the worm 505 is driven to rotate, thereby driving the transmission gear 504 to rotate, and then driving the driving gear 502 to rotate, so that the driving motor 501 and the driving gear 502 can be driven and connected. In other embodiments, the driving motor 501 can also be driven and connected with the driving gear 502 through other transmission structures (for example, through a bevel gear), which is not limited to this.

[0035] Please continue reading Figure 3 and Figure 4 Furthermore, in the illustrated embodiment, the driving mechanism 50 further includes a plurality of rollers 503. In this embodiment, the number of rollers 503 is four, and the four rollers 503 are arranged in pairs on opposite sides of the massage mechanism 40. In other embodiments, the number of rollers 503 can also be any number such as two, three, five, six, etc., and the positions of the plurality of rollers 503 can also be set arbitrarily. The guide rail mechanism 30 is also provided with roller grooves 302 in parallel, and the roller grooves 302 are recessed relative to the convex teeth 301. The rollers 503 are arranged in the roller grooves 302 and can rotate in the roller grooves 302.

[0036] Through the above arrangement, when the massage mechanism 40 moves along the guide rail mechanism 30, the roller 503 can rotate in the roller groove 302 and move along the roller groove 302. The cooperation between the roller 503 and the roller groove 302 can make the movement of the massage mechanism 40 more stable and reduce the noise generated when the massage mechanism 40 moves. In addition, since the roller groove 302 is recessed relative to the convex tooth 301, the roller 503 located in the roller groove 302 can be partially blocked by the convex tooth 301, so that the roller 503 can be limited (i.e., prevent the roller 503 from accidentally falling out of the roller groove 302), and at the same time, it can ensure that the convex tooth 301 and the driving gear 502 are more firmly and reliably meshed, further improving the stability and reliability of the movement of the massage mechanism 40.

[0037] In some embodiments, two groups of guide rail mechanisms 30 are provided, and the two groups of guide rail mechanisms 30 are arranged at intervals, and a clearance space 303 is formed between the two groups of guide rail mechanisms 30, and the clearance space 303 is used to allow the massage mechanism 40 and the support member 601 to move. Through the above arrangement, the clearance space 303 allows the massage mechanism 40 and the support member 601 to have enough space to move, and the two groups of guide rail mechanisms 30 can also form a good support and guidance effect on the massage mechanism 40.

[0038] In some embodiments, the side of the support member 601 facing the seat space 70 is a planar structure for supporting the user's waist and back, and the side of the support member 601 away from the seat space 70 is a planar structure. Through the above arrangement, the support member 601 as a whole is generally flat (e.g., plate-shaped) structure, which not only occupies a small space, but also has a large support area, and can effectively support the user's waist and back. In some other embodiments, the side of the support member 601 facing the seat space 70 can also be a curved surface that adapts to the curve of the human waist and back, and there may be a convex structure or a concave structure on its surface to better adapt to the user's waist and back structure, thereby improving the support effect and support comfort. In addition, the support member 601 can be made of a rigid material, or made of a flexible material and a rigid material, without limitation.

[0039] In addition, in some embodiments, the support member 601 may be provided with a plurality of ventilation holes (not shown in the figure), which are through holes provided on the support member 601. The ventilation holes can increase the air permeability of the user's waist and back when leaning against the support member 601, further improving the user's comfort.

[0040] In summary, the present embodiment provides a sofa frame 100, which includes a cushion frame 10, a backrest frame 20, a guide rail mechanism 30, a massage mechanism 40, a drive mechanism 50 and a support mechanism 60. The sofa frame 100 can control the massage mechanism 40 to move back and forth between the cushion frame 10 and the backrest frame 20 along the guide rail mechanism 30 through the drive mechanism 50, and can also drive the support member 601 to move between the first position and the second position through the support mechanism 60; when the user needs a massage, the support drive member 602 drives the support member 601 to move to the first position relatively away from the seat space 70, so as to Providing a space 303 for the massage mechanism 40, the driving mechanism 50 drives the massage mechanism 40 to move along the guide rail mechanism 30 to the position of the backrest frame 20 to massage the user's waist and back; when the massage is finished, the driving mechanism 50 drives the massage mechanism 40 to move along the guide rail mechanism 30 to the position of the cushion frame 10, and the support driving member 602 drives the support member 601 to move to a second position relatively close to the seat space 70 to support the user's waist and back, and the support height of the support member 601 can also be linearly adjusted, which greatly meets the diverse use needs of different users and improves the user's comfort. Therefore, the sofa frame 100 has the beneficial effects of good massage effect, good user experience, and the ability to meet the diverse use needs of users.
