Description

Technical Field

[0001] The present invention relates to the technical field of massage equipment, and in particular to improvements on a chair frame structure in a full-body massage machine, aiming to provide a chair frame structure that can ensure smooth movement of a massage movement on the chair frame, improve massage effects and user experience, and a full-body massage machine comprising the chair frame. Background Art

[0002] With the acceleration of the pace of life and the improvement of people's attention to health, massage machines, as a household appliance that can relieve physical fatigue and promote blood circulation, have become more and more popular. Full body massage machines, as a type of massage machine, massage the user's whole body by simulating the movements and strength of manual massage, thereby achieving the effect of relaxing muscles and relieving stress. However, existing full body massage machines still have some shortcomings in the design of the chair frame, especially in the guide rail system that guides the movement of the massage movement. These problems directly affect the comfort and effect of the massage.

[0003] The traditional full body massage chair frame usually includes a back frame, a seat frame and a guide device connecting the two. The back frame adjusts the angle with the seat frame by rotating around a set axis to adapt to the body curves and massage needs of different users. However, this design forms a gap between the back frame and the seat frame, and the massage movement needs to move smoothly in this gap to achieve continuous massage from the back to the seat. Although the existing guiding devices, such as the back frame guide rail, the seat frame guide rail and the connecting guide rail, can basically achieve this function, in actual use, the connecting guide rail is easily elastically deformed due to the influence of the weight and moving force of the massage movement, causing the massage movement to be bumpy or stuck during movement, which seriously affects the smoothness and comfort of the massage.

[0004] To solve this problem, the industry has tried various methods, such as increasing the rigidity of the guide rails, optimizing the shape of the guide rails, etc., but these methods often come at the expense of increasing costs or sacrificing the overall flexibility of the chair frame. For example, simply increasing the rigidity of the guide rails may make the chair frame bulky and difficult to adjust, while optimizing the shape of the guide rails may limit the range of movement of the massage mechanism. Therefore, how to ensure the smooth movement of the massage mechanism in the gap while keeping the chair frame light and flexible has become a technical problem that needs to be solved urgently.

[0005] In addition, the adaptability of existing massage chair frames to different user body shapes and massage needs needs to be improved. Traditional chair frame structures often use a fixed rail layout, which is difficult to adjust according to the specific needs of users. This not only limits the scope of use of the massage machine, but also reduces the user's massage experience.

[0006] In summary, the existing full-body massage chair frame has many deficiencies in the design of the guide rail system, smoothness guarantee, and personalized adjustment. Therefore, the present invention aims to provide an improved chair frame structure, which effectively regulates the elastic deformation of the connecting guide rail by introducing a deformation regulation mechanism to ensure the smooth movement of the massage core in the interval gap; at the same time, the chair frame structure should also have good flexibility and adaptability to meet the massage needs of different users.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various configurations. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0039] Combination Figures 1 to 7 In one embodiment, the whole body massage machine of the present application is a massage chair, which includes a chair frame and a massage movement T. The massage movement T is installed on the chair frame and can move along the chair frame to massage the user. In this embodiment, the chair frame includes a base frame 1, a back frame 2, a seat frame 3, a driving mechanism 4, a deformation regulating mechanism 5, and a guiding device P. The following will describe each component in detail with reference to the drawings. For the convenience of description, Figure 1 The X direction is from right to left, the Y direction is from front to back, and the Z direction is from bottom to top.

[0040] [Base] Base 1 is the part of the chair frame that supports the ground. Figure 4 In this embodiment, the left and right sides of the base frame 1 have a first guide rail 1A and a second guide rail 1B. The first guide rail 1A gradually tilts upward from the back to the front, and the tilt angle is, for example, between 10 degrees and 30 degrees, such as 20 degrees. The second guide rail 1B gradually tilts downward from the back to the front, and the tilt angle is, for example, between 60 degrees and 80 degrees, such as 70 degrees. The lower side of the second guide rail 1B is roughly located on the upper side of the middle of the first guide rail 1A. The first guide rail 1A is used to roll with the seat frame roller N1 of the seat frame 3, and the second guide rail 1B is used to roll with the back frame roller N2 of the back frame 2.

[0041] [Back frame] The back frame 2 is used to support the back and head of the user. The back frame 2 has back frame rollers N2 located on the left and right sides. The back frame rollers N2 roll with the second guide rail 1B.

[0042] [Seat] The seat 3 is used to support the user's buttocks. The seat 3 has seat rollers N1 located on the left and right sides. The seat rollers N1 roll with the first guide rail 1A. The back frame 2 adjusts the treatment angle between it and the seat 3 by rotating around a set axis. In this embodiment, the left and right sides of the back frame 2 are pivotally connected to the seat 3 by a pivot member. A gap S is formed between the back frame 2 and the seat 3. Combination Figure 4 , Figure 6 The seat frame 3 includes a seat frame body 3A, a limiting member 3B for limiting the first elastic plate 6 from upwardly separating from the seat frame body 3A, a first limiting block 3C engaged with the first elastic plate 6, and a second limiting block 3D engaged with the seat frame guide rail P2 and the second elastic plate 7. The limiting member 3B is detachably mounted on the seat frame body 3A, and an installation space for configuring the first elastic plate 6 is formed between the limiting member 3B and the seat frame body 3A. The first limiting block 3C is located between the limiting member 3B and the seat frame body 3A in the up and down directions.

[0043]

Drive mechanism

[0044] [Guiding device] The guiding device P is used to guide the massage movement T to move on the user's back and seat. Figures 1 to 6 , which includes a back frame guide rail P1, a seat frame guide rail P2 and a connecting guide rail P3. The back frame guide rail P1 is located on the back frame 2, the seat frame guide rail P2 is located on the seat frame 3, and the connecting guide rail P3 is arranged at the interval S to connect the back frame guide rail P1 and the seat frame guide rail P2. The massage movement T has a running gear that matches the back frame guide rail P1, the seat frame guide rail P2 and the connecting guide rail P3. The massage movement T is a common structure and will not be described in detail.

[0045] Combination Figure 4In this embodiment, the back frame rail P1 includes a back frame rail body P11 and a detachable part P12, and the detachable part P12 is detachably mounted on the back frame rail body P11. When the detachable part P12 is detached, the massage movement T can be disassembled and assembled on the back frame rail body P11. In this embodiment, the back frame rail P1 is mounted on the back frame 2 through a fastening structure, but it should be understood that in another embodiment, the back frame rail P1 can be designed to be integrally formed with the back frame 2, such as integrally formed by injection molding.

[0046] Combination Figure 4 , Figure 6 and Fig.10 The front side of the seat frame guide rail P2 has a seat frame guide rail installation groove K, and the second limit block 3D is embedded in the seat frame guide rail installation groove K. The size of the seat frame guide rail installation groove K in the front-to-back direction is slightly larger than the size of the second limit block 3D, so that the seat frame guide rail P2 and the seat frame 3 slide in cooperation in the front-to-back direction. When the inclination angle of the back frame 2 relative to the seat frame 3 changes, the seat frame guide rail P2 slides back and forth relative to the seat frame 3 adaptively. Specifically, when the back frame 2 rotates backward, the seat frame guide rail P2 slides backward, and correspondingly, when the back frame 2 rotates forward, the seat frame guide rail P2 slides forward. The seat frame guide rail P2 and the seat frame 3 slide in cooperation in the front-to-back direction, which can ensure that the connecting rail P3 can bend and change its angle adaptively and flexibly when the back frame 2 rotates relative to the seat frame 3.

[0047] Combination Figure 4 , Figure 6 and Fig.10 In this embodiment, the connecting rail P3 and the seat frame rail P2 are an integrated structure, and the two can be integrally formed by injection molding. Figure 6 As shown, the back frame rail P1 has a first joint portion Q1, and the connecting rail P3 has a second joint portion Q2, which is compatible with the first joint portion Q1 structure (in this embodiment, it is a compatible interlocking structure), so that the back frame rail P1 and the connecting rail P3 can be connected so that the massage movement T can move between them. Figures 8 to 11 The connecting rail P3 has an extension portion P31 extending between the second elastic plate 7 and the spacing member 8A, the extension portion P31 is closely fitted with the second elastic plate 7, and the spacing member 8A is pressed against the extension portion P31, that is, the spacing plate 8A is indirectly pressed against the second elastic plate 7. In another embodiment, it can be adjusted so that the spacing plate 8A is directly pressed against the second elastic plate 7.

[0048] [Deformation regulation mechanism] The deformation regulation mechanism 5 is used to regulate the elastic deformation of the connecting guide rail P3, so as to provide a smooth moving track for the massage movement T of the massage machine at the interval S. Figures 8 to 11The deformation regulation mechanism 5 includes a first elastic plate 6, a second elastic plate 7, and a plurality of spacing maintaining devices 8. The first elastic plate 6 and the second elastic plate 7 are arranged in parallel, and the spacing maintaining devices 8 are suitable for maintaining the spacing between the first elastic plate 6 and the second elastic plate 7 at the spacing gap S to be substantially the same. The first elastic plate 6 and the second elastic plate 7 are made of spring steel, for example.

[0049] The two ends of the first elastic plate 6 are respectively fixed to the back frame 2 and the seat frame 3. Specifically, Fig.10 The upper side of the first elastic plate 10 has a snap-in hole 6B, and the back frame 2 has a corresponding snap-in portion. The snap-in portion is embedded in the snap-in hole 6B to fix the first elastic plate 6 to the back frame 2. The front side of the first elastic plate 6 has a mounting groove 6A. The position of the mounting groove 6A corresponds to the position of the first limit block 3C, and the first limit block 3C is embedded in the mounting groove 6A. The size of the mounting groove 6A in the front-to-back direction is slightly larger than the size of the first limit block 3C, so that the first elastic plate 6 and the seat frame 3 slide in cooperation in the front-to-back direction. Fig.10 , the dimension H2 of the installation slot 6A in the front-to-back direction is greater than the dimension H1 of the seat frame guide rail installation slot K in the front-to-back direction. This design method enables the displacement of the first elastic plate 6 to slide forward and backward relative to the seat frame 3 to be slightly greater than the displacement of the seat frame guide rail P2 to slide forward and backward relative to the seat frame 3. The first elastic plate 6 and the seat frame 3 slide in cooperation in the front-to-back direction, which can ensure that the angle of the connecting guide rail P3 can be adaptively and flexibly bent when the back frame 2 rotates relative to the seat frame 3.

[0050] The two ends of the second elastic plate 7 are respectively fixed to the back frame 2 and the seat frame 3. Specifically, Fig.10 The front and rear ends of the second elastic plate 7 have engaging holes 7A and 7B respectively. The position of the engaging hole 7A corresponds to the position of the second limit block 3D and the seat frame guide rail mounting groove K. The back frame 2 has an engaging portion corresponding to the engaging hole 7B. The engaging holes 7A and 7B are engaged with the corresponding engaging portions on the first limit block 3A and the back frame 2, so that the two ends of the second elastic plate 7 are fixed to the back frame 2 and the seat frame 3 respectively. The seat frame guide rail P2 and the second elastic plate 7 are both engaged with the seat frame 3 through the second limit block 3D, so that the overall structure of the chair frame is more compact. In another embodiment, the second elastic plate 7 can also be adjusted to slide with the seat frame 3.

[0051] In this embodiment, there are five spacing maintaining devices 8, namely, a first spacing maintaining device 8-1, a second spacing maintaining device 8-2, a third spacing maintaining device 8-3, a fourth spacing maintaining device 8-4, and a fifth spacing maintaining device 8-5, and the five spacing maintaining devices 8 are arranged at intervals in the extension direction of the connecting guide rail P3. In this embodiment, the spacing maintaining device 8 includes a spacing member 8A, an upper support member 8B, and a lower support member 8C, and the spacing member 8A, the upper support member 8B, and the lower support member 8C can all be rotatably engaged on the substrate (lower substrate M1, middle substrate M2, upper substrate M3).

[0052] Specifically, combined Fig.10 In this embodiment, the spacer member 8A has a side wall N1 located outside in the left-right direction, an upper abutment portion N2 located on the upper side of the side wall N1, and a lower abutment portion N3 located on the lower side of the side wall N1. The spacer member 8A is connected to the substrate (lower substrate M1, middle substrate M2, upper substrate M3) through the side wall N1. In this embodiment, the side wall N1 is rotatably connected to the substrate (lower substrate M1, middle substrate M2, upper substrate M3).

[0053] The upper support member 8B is located on the upper side of the upper abutment portion N2 of the spacing member 8A, and an upper clamping space for clamping the first elastic plate 6 is formed therebetween, so that the first elastic plate 6 can be clamped between the spacing member 8A and the upper support member 8B. The lower support member 8C is located on the lower side of the lower abutment portion N3 of the spacing member 8A, and a lower clamping space for clamping the second elastic plate 7 is formed therebetween, so that the second elastic plate 7 is clamped between the spacing member 8A and the lower support member 8C. The upper and lower ends of the spacing member 8A (i.e., the upper abutment portion N2 and the lower abutment portion N3) are respectively suitable for pressing the first elastic plate 6 and the second elastic plate 7 to maintain the distance between the two (as mentioned above, in this embodiment, the spacing member 8A is indirectly pressed on the second elastic plate 7). The top surface of the spacing member 8A (the upper surface of the upper abutment portion N2) is configured as an upper convex arc surface to adapt to the elastic deformation of the first elastic plate 6, and the bottom surface thereof (the lower surface of the lower abutment portion N3) is configured as a lower convex arc surface to adapt to the elastic deformation of the second elastic plate 7. In this embodiment, the upper support member 8B and the lower support member 8C are both configured in a roller shape and are rotatably engaged on the substrates (the lower substrate M1, the middle substrate M2, and the upper substrate M3).

[0054] The first spacing device 8-1 and the second spacing device 8-2 are both disposed on the lower substrate M1, and the lower substrate M1 is movably connected to the seat frame 3 by the first connecting rod L1 (combined with Figures 7 to 10 ), in this embodiment, the first connecting rod L1 is rotatably connected to the lower substrate M1 and the seat frame 3, but it can also be adjusted to a ball joint or other connection method. The first spacing holding device 8-1 and the second spacing holding device 8-2 constitute a set of spacing holding devices connected to the seat frame 3.

[0055] The third spacing maintaining device 8-3 and the fourth spacing maintaining device 8-4 are both arranged on the middle substrate M2, and the middle substrate M2 is movably connected to the back frame 2 by the second connecting rod L2 (combined with Figures 7 to 10 ), in this embodiment, the second connecting rod L2 is rotatably connected to the middle base plate M2 and the back frame 2, but it can also be adjusted to a ball joint or other connection method. The third spacing holding device 8-3 and the fourth spacing holding device 8-4 constitute a set of spacing holding devices connected to the back frame 2.

[0056] The fifth spacing maintaining device 8-5 is arranged on the upper substrate M3, and the upper substrate M3 is movably connected to the second connecting rod L2 through the third connecting rod L3 (combined with the upper substrate M3). Figures 8 to 10 ), in this embodiment, the third connecting rod L3 can be rotatably connected to the upper substrate M3 and the second connecting rod L2, but it can also be adjusted to a ball hinge or other connection method.

[0057] By adopting the above structure, when the back frame 2 rotates relative to the seat frame 3, the curvature of the first elastic plate 6 and the second elastic plate 7 at the spacing gap S is constantly changing, and the spacing maintaining device 8 can make the spacing between the first elastic plate 6 and the second elastic plate 7 at the spacing gap remain basically the same, so that the massage movement can move smoothly on the chair frame, thereby improving the massage effect and user experience.

[0058] [Variant Implementation] The above is the specific structure of the massage machine of one embodiment of the present application, but it should be understood that the specific implementation of the present application is not limited to this. In another embodiment, the fifth spacing maintaining device 8-5 can be omitted. In another embodiment, the seat frame 3 can be fixed on the base frame 1 so that the back frame 2 rotates around the set axis (rotates relative to the seat frame or the base frame). In another embodiment, the front side of the seat frame 3 can be pivotally connected to a lower limb massage device, and the seat frame 3 can be installed with a lower limb drive mechanism that drives the lower limb massage device to flip. In another embodiment, the spacing maintaining device 8 can be adjusted to have only one group (the number can be adjusted according to the size of the spacing gap S) and connected to the back frame 2 or the seat frame 3. In another embodiment, the back frame 2 or the seat frame 3 is equipped with an armrest to support the user (the armrest can be equipped with a structure for massaging the hands such as an air bag), and at least one spacing maintaining device 8 can be connected to the armrest.

[0059] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
