Description

Technical Field

[0001] The invention relates to massage equipment technology, in particular to a massage chair suitable for full body massage. Background Art

[0002] A massage chair is a common massage device. Taking a common shared massage chair as an example, a massage chair usually includes a seat and a back. A common design method is to design the back of the massage chair to be able to rotate forward and backward relative to the seat, and a massage movement is provided on the back. The disadvantage of this method is that the massage movement can only move on the back, and the massage area is relatively limited. Another common design method is that the back and the seat cannot rotate relative to each other, and the massage movement is designed to be able to move between the back and the seat. The disadvantage of this method is that the supporting posture of the user supported by the massage chair cannot be changed. Patent application CN103690334B discloses a chair-type full-body massager to solve the deficiencies of the aforementioned two design methods, but the technical solution of this application is relatively complicated. In view of this, this application is specially proposed. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a massage chair which is different from the prior art and can perform full body massage.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a massage chair suitable for full-body massage, comprising a back with a back guide rail, a seat with a seat guide rail, and a massage movement suitable for moving along the back guide rail and the seat guide rail, wherein the back is configured to be able to rotate relative to the seat to change the user's reclining angle; the seat guide rail comprises: a deformation segment suitable for generating elastic deformation and a connecting segment movably connected to the seat; wherein the deformation segment is configured to extend in a direction suitable for connecting to the back guide rail and is fixed to the back; in the process of changing the reclining angle, the back can drive the deformation segment to generate elastic deformation suitable for the movement of the massage movement, and in response to the elastic deformation, the connecting segment is driven to move to reduce the deformation stress generated on the deformation segment.

[0005] Preferably, the connecting section is slidably matched with the seat.

[0006] Preferably, the teeth of the seat guide rail and the back guide rail are arranged to face away from the side of the massage chair supporting the user.

[0007] Preferably, one of the connecting section and the seat has a guide groove, and the other has a guide rod, and the guide groove and the guide rod are slidably matched.

[0008] Preferably, the back guide rail is integrally formed with the back.

[0009] Preferably, the seat part, the back part, the seat guide rail and the back guide rail are injection molded parts.

[0010] Preferably, the seat part is mounted on the seat frame, the back part is mounted on the back frame, and the back part can rotate back and forth relative to the seat part by means of pivotally connecting the seat frame and the back frame.

[0011] Preferably, the reclining drive mechanism for controlling the rotation of the back part relative to the seat part is arranged between the seat frame and the back frame.

[0012] Preferably, the seat frame is movably mounted on the chassis in the front-back direction.

[0013] Preferably, a lower limb massage device is provided on the front side of the seat frame.

[0014] Due to the adoption of the above technical solutions, the present invention has the following beneficial effects:

[0015] 1. The massage chair of the present application is suitable for full-body massage. The back part can rotate relative to the seat part to adjust the reclining angle of the massage chair. During the process of changing the reclining angle, the back part can drive the deformation section of the seat guide rail to generate an elastic deformation suitable for the walking of the massage mechanism. In response to the elastic deformation, the connecting section of the seat guide rail is driven to move to reduce the deformation stress generated on the deformation section. Through the above solution, the massage mechanism can move between the back part and the seat part at different reclining angles of the massage chair.

[0016] 2. The tooth parts of the seat guide rail and the back guide rail are arranged facing away from the side of the massage chair that supports the user. In this design, the seat guide rail and the back guide rail do not directly support the massage mechanism, the load is small, and the resistance suffered by the connecting section of the seat guide rail during movement is small, making it easier to move when the back part rotates relative to the seat part.

[0017] 3. When the back part of the massage chair of the present application rotates backward relative to the seat part (i.e., switches from the sitting posture state to the lying posture state), the connecting section of the seat guide rail moves forward relative to the seat part, the stroke of the massage mechanism on the seat part increases, and the massage coverage area increases.

Detailed implementation manners

[0027] To make the objectives, technical solutions, 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. Usually, the components of the embodiments of the present invention described and illustrated in the drawings here can be arranged and designed in various different configurations. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the features in the following embodiments can be combined with each other.

[0029] Combined with Figures 1 to 5 , in an embodiment, a massage chair suitable for full-body massage according to the present application includes an underframe 1, a seat frame 2, a back frame 3, a lower limb massage device 4, a seat frame drive mechanism 5, a reclining drive mechanism 6, a lower limb drive mechanism 7, a transmission swing rod 8, a seat part Q1, a back part Q2, a seat rail M1, a back rail M2, and a massage mechanism P. The seat rail M1 and the back rail M2 cooperate to form a rail for the massage mechanism P to travel, and the massage mechanism P can move along the back part Q2 to the seat part Q1 (see Figure 1 and Figure 2, for ease of understanding, the massage mechanism P is shown in both the back part Q2 and the seat part Q1 in the illustration. For ease of understanding, the X direction in the illustration is defined as the front - back direction, the Y direction as the left - right direction, and the Z direction as the up - down direction.

[0030] The chassis 1 has seat frame slide rails 1A located on the left and right sides and a swing frame 1B located on the front side. The chassis 1 may be provided with ground - touching rollers to facilitate the handling of the massage chair. The swing frame 1B can swing back and forth.

[0031] Both left and right sides of the seat frame 2 have roller members that roll - fit with the seat frame slide rails 1A. The front side of the seat frame 2 is pivotally connected to the swing frame 1B. The seat frame driving mechanism 5 (a telescopic push rod in this embodiment) is located between the chassis 1 and the seat frame 2 (pivotally connected to both respectively). When the seat frame driving mechanism 5 expands and contracts, the seat frame 2 moves back and forth relative to the chassis 1.

[0032] The backrest frame 3 is pivotally connected to the seat frame 2. The reclining driving mechanism 6 (a telescopic push rod in this embodiment) is located between the backrest frame 3 and the seat frame 2 (pivotally connected to both respectively). When the reclining driving mechanism 6 expands and contracts, it drives the backrest frame 3 to rotate back and forth relative to the seat frame 2, changing the reclining angle of the massage chair.

[0033] The lower - limb massage device 4 is pivotally connected to the front side of the seat frame 2 so as to be rotatable up and down. The lower - limb driving mechanism 7 (a telescopic push rod in this embodiment) is installed between the seat frame 2 and the transmission swing rod 8. The upper side of the transmission swing rod 8 is pivotally connected to the seat frame 2. The front side of the transmission swing rod 8 abuts against the rear side of the lower - limb massage device 4. The lower - limb driving mechanism 7 is pivotally connected to the middle of the transmission swing rod 8. When the lower - limb driving mechanism 7 expands and contracts, it drives the transmission swing rod 8 to swing, thereby controlling the up - and - down flipping of the lower - limb massage device 4.

[0034] Combined Figures 6 to 8 , the seat part Q1 is installed on the seat frame 2. The seat part Q1 includes first seat components Q11 located on the left and right sides and a second seat component Q12 located in front of the first seat components Q11. The two first seat components Q11 and the second seat component Q12 cooperate to form a generally U - shaped structure. When the massage mechanism P moves at the seat part Q1 position, it can massage the user's buttocks and thighs.

[0035] The back part Q2 is installed on the backrest frame 3. The back part Q2 includes first back components Q21 located on the left and right sides and a second back component Q22 located above the first back components Q21. The two first back components Q21 and the second back component Q22 cooperate to form a generally U - shaped structure. A strengthening connecting rod is provided between the rear sides of the two first back components Q21. When the massage mechanism P moves at the back part Q2 position, it can massage the user's back and waist. Through the pivotal connection between the backrest frame 3 and the seat frame 2, the back part Q2 can rotate back and forth relative to the seat part Q1, adjusting the reclining angle of the massage chair, thereby changing the posture of supporting the user.

[0036] The seat guide rail M1 and the back guide rail M2 are adjacent to each other to allow the massage mechanism P to travel therebetween. In combination with Figures 6 to 10 , in this embodiment, the seat guide rail M1 includes a deformation section M12 adapted to generate elastic deformation and a connection section M11 movably connected to the seat Q1. The deformation section M12 is configured to extend in a direction adapted to be connected to the back guide rail M2 and is fixedly connected to the back Q2 (the back Q2 has a fitting groove adapted to the end of the deformation inclination M12, and the two can be fixedly connected by screws). During the process of changing the reclining angle of the massage chair, the back Q2 can drive the deformation section M12 to generate elastic deformation suitable for the massage mechanism P to travel (in combination with the figure, the part of the deformation section M12 connected to the connection section M11 is arc-shaped and can generate elastic deformation), and in response to the elastic deformation, the connection section M11 is driven to move to reduce the deformation stress generated on the deformation section M12.

[0037] In this embodiment, the connection section M11 of the seat guide rail M1 is in sliding fit with the seat Q1. Specifically, in combination with Figure 6 , the connection section M11 of the seat guide rail M1 has a guide groove S, and the seat Q1 correspondingly has a guide rod K. The guide groove S and the guide rod K are in sliding fit, so that the connection section M1 and the seat Q1 are in sliding fit. It should be understood that the positions of the guide groove S and the guide rod K can be swapped. The deformation section M12 is fixedly joined to the back Q2 (the two can be joined by fastening screws). In this embodiment, the back guide rail M2 and the back Q2 are fixedly joined in an integrally formed manner, but it should be understood that the two can also be a split structure and are fixedly joined by fastening screws. In this embodiment, the tooth portions of the seat guide rail M1 and the back guide rail M2 are arranged to face away from the side of the massage chair that supports the user (i.e., face downward). Compared with the way of being arranged to face the side of the massage chair that supports the user, designed to face away from the side of the massage chair that supports the user, the seat guide rail M1 and the back guide rail M2 do not directly support the massage mechanism P, the load is smaller, and the resistance suffered by the connection section M11 of the seat guide rail M1 during movement is smaller, and it is easier to move when the back Q2 rotates relative to the seat Q1. It should be understood that the tooth portions of the seat guide rail M1 and the back guide rail M2 can also be arranged to face the side of the massage chair that supports the user. When the back Q2 rotates backward relative to the seat Q1 (i.e., switches from the sitting posture state to the lying posture state), the connection section M11 of the seat guide rail M1 moves forward relative to the seat Q1, the stroke of the massage mechanism P on the seat Q1 increases, and the massage coverage area increases.

[0038] The massage mechanism P has a roller member and a gear member, and its specific structure is, for example, the massage mechanism disclosed in the prior art such as Patent Application CN201920427248.4. The gear member of the massage mechanism P can be meshed with the seat guide rail M1 and the back guide rail M2. In combination with Figure 7, on the left and right sides of the seat part Q1, there are seat part roller running grooves N1 for the roller parts of the massage mechanism P to run. On the left and right sides of the back part Q2, there are back part roller running grooves N2 for the roller parts of the massage mechanism P to run. The positions of the seat part roller running grooves N1 and the back part roller running grooves N2 correspond to each other.

[0039] In this embodiment, the seat part Q1, the back part Q2, the seat guide rail M1 and the back guide rail M2 are all injection-molded parts.

[0040] The above are all the massage chairs of an embodiment of the present application. However, it should be understood that the implementation manners that the massage chair of the present application can adopt are not limited to this.

[0041] In another embodiment, the seat frame 2 can be set to be fixed on the chassis 1, and the seat frame driving mechanism 5 can be omitted. On this basis, the reclining driving mechanism 6 for driving the back frame 3 to rotate relative to the seat frame 2 can also be adjusted to be arranged between the back frame 3 and the chassis 1.

[0042] In another embodiment, the seat frame 2 and the seat part Q1 can be an integral structure, the back frame 3 and the back part Q2 can be an integral structure, or the seat frame 2 and the back frame 3 can be omitted, so that the seat part Q1 and the back part Q2 are directly rotationally engaged.

[0043] The above are only the specific implementation manners of the present invention. However, the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
