Description

Technical Field

[0001] This utility model relates to the field of massage chair technology, and more specifically, to a massage chair frame. Background Technology

[0002] In the prior art, massage chairs, especially those with reclining posture adjustment, typically include a seat backrest, a base frame, and a leg rest. The seat backrest and the base frame are movably connected by a linkage structure, and the entire seat backrest is tilted and rotated by a backrest electric push rod located between the seat backrest and the base frame, thereby realizing the adjustment and switching between sitting and reclining postures. The leg rest is flipped over by another leg electric push rod.

[0003] Among them, most of the existing linkage structures are relatively complex and have many components, which leads to slow overall adjustment of the seat frame, and the complexity and number of parts also increase the cost. Utility Model Content

[0004] This utility model overcomes the shortcomings of the prior art. Its structure is reasonably designed. Through the structure of the swing rod and the limiting component, the state of the seat and backrest can be adjusted. Moreover, since there are no other additional transmission components, the swing is faster. The structure is reliable and stable when the seat and backrest are in a sitting or lying position.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A massage chair frame includes a base frame, a seat backrest hinged to the base frame, and a backrest electric push rod for driving the seat backrest to rotate. At least two sets of swing arms are hinged between the seat backrest and the base frame, wherein the two sets of swing arms are limit rods, and the two sets of limit rods are spaced apart. A limit member is provided on the base frame, and the limit member is located between the two sets of limit rods. Each end of the limit member is provided with a limit end opposite to the two sets of limit rods. When the seat backrest is adjusted to a sitting position, one set of limit rods abuts against the opposite limit end and is restricted from swinging by the limit member. When the seat backrest is adjusted to a reclining position, the other set of limit rods abuts against the opposite limit end and is restricted from swinging by the limit member.

[0006] By adopting the above technical solution, and by setting two sets of limiting rods and limiting components, with limiting ends at both ends of the limiting components that abut against the two sets of limiting rods, the electric push rod of the backrest is driven to swing the swing arm, allowing the seat frame to switch between sitting and lying positions relative to the base frame. The limiting ends limit the limiting rods, ensuring the seat frame can be stably positioned in either sitting or lying position. Specifically, there can be three sets of swing arms: two sets that cooperate with the limiting components, and the third set that provides good swing stability and support. Of course, other numbers of swing arms can be used, such as four or five sets, but three sets offer both support stability and cost-effectiveness. With this configuration, the state of the seat frame can be adjusted through the structure of the swing arms and limiting components. Furthermore, since there are no other additional transmission components, the swing is rapid, and the structure of the seat frame is robust and stable in both sitting and lying positions.

[0007] Preferably, the limiting member is parallel to the base frame, and both sets of limiting ends are set as inclined surfaces with opposite inclination angles.

[0008] By adopting the above technical solution, since the two sets of limit rods will be in an inclined state when swinging, by setting the limit end as an inclined surface, the two inclined surfaces cooperate when the limit rod swings to abut against the limit end. By having the two sets of inclined surfaces tilt at opposite angles, the overall structure is more aesthetically pleasing. Furthermore, the length and setting position of the two sets of limit rods need to be reasonably designed so that the seat backrest provides better comfort for the user when in a sitting or lying position.

[0009] Preferably, a connecting rod is fixedly connected between the limiting component and the base frame, and the connecting rod and the limiting component are fixed or integrally set.

[0010] By adopting the above technical solution, the limiting component is stably fixed on the base frame. When the corresponding limiting rod abuts against the limiting end, part of the force on the limiting component can be transferred to the base frame, thus making the overall support better and reducing the likelihood of the seat frame wobbling.

[0011] Preferably, the seat frame is provided with a flexible guide rail, the seat frame includes a backrest and a seat that are rotatably connected, and at least one set of swing rods is provided at the position corresponding to the backrest and at least one set of swing rods is provided at the position corresponding to the seat.

[0012] By adopting the above technical solution, a walking massage mechanism can be installed on the flexible guide rail to provide a massage effect. When the seat frame is in a sitting position, the seat does not rotate relative to the backrest. However, when the seat frame is in a reclining position, the seat rotates relative to the backrest, allowing for a larger overall opening range and providing better comfort for the user. Furthermore, when the electric push rod of the backrest extends or retracts, multiple sets of swing rods of different lengths allow for changes in the angle between the seat and the backrest, thus achieving overall swinging of the seat and backrest.

[0013] Preferably, it also includes a leg support hinged to the seat frame and a leg electric push rod that drives the leg support to rotate. The backrest electric push rod is hinged between the base frame and the seat frame, and the leg electric push rod is hinged between the seat frame and the leg support.

[0014] By adopting the above technical solution, the calf support is set up so that the calf support can be opened or closed relative to the seat frame by the electric calf push rod, which brings better support and comfort to the user's legs. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-3 As shown, a massage chair frame includes a base frame 1, a seat backrest 2 hinged to the base frame 1, and a backrest electric push rod 3 for driving the seat backrest 2 to rotate. At least two sets of swing rods 4 are hinged between the seat backrest 2 and the base frame 1, wherein the two sets of swing rods 4 are limiting rods 41, and the two sets of limiting rods 41 are spaced apart. A limiting member 5 is provided on the base frame 1, and the limiting member 5 is located between the two sets of limiting rods 41. The two ends of the limiting member 5 are respectively provided with limiting ends 51 opposite to the two sets of limiting rods 41. When the seat backrest 2 is adjusted to a sitting position, one set of limiting rods 41 abuts against the opposite limiting end 51 and is restricted from swinging by the limiting member 5. When the seat backrest 2 is adjusted to a reclining position, the other set of limiting rods 41 abuts against the opposite limiting end 51 and is restricted from swinging by the limiting member 5.

[0019] By adopting the above technical solution, and by setting two sets of limiting rods 41 and limiting components 5, with limiting ends 51 at both ends of the limiting components 5 abutting against the two sets of limiting rods 41, the electric push rod 3 of the backrest drives the swing rod 4 to swing, allowing the seat frame 2 to switch between sitting and lying positions relative to the base frame 1. The limiting ends 51 limit the limiting rods 41, ensuring the seat frame 2 can stably maintain a sitting or lying position. Specifically, the swing rod 4 can be set to three sets, with two sets being limiting rods 41 that cooperate with the limiting components 5, and the other set providing good swing stability and better support. Of course, other numbers of swing rods 4 can be set, such as four or five sets, but setting three sets of swing rods 4 combines support stability with cost-effectiveness. With this configuration, the state adjustment of the seat frame 2 can be achieved through the structure of the swing rods 4 and limiting components 5. Furthermore, since there are no other additional transmission components, the swing is rapid, and the structure of the seat frame 2 is robust and stable when in a sitting or lying position.

[0020] The limiting component 5 is parallel to the base frame 1. Both sets of limiting ends 51 are set as inclined surfaces 52. The inclination angles of the two sets of inclined surfaces 52 are opposite. Since the two sets of limiting rods 41 will be in an inclined state when swinging, by setting the limiting ends 51 as inclined surfaces 52, the inclined surfaces 52 of the two limit rods 41 will cooperate when swinging to abut against the limiting ends 51. By setting the inclination angles of the two sets of inclined surfaces 52 to be opposite, the overall structure is more aesthetically pleasing. In addition, the length and setting position of the two sets of limiting rods 41 need to be reasonably designed so that the seat and backrest 2 can provide better comfort for users when in a sitting or lying position.

[0021] A connecting rod 53 is fixedly connected between the limiting member 5 and the base frame 1. The connecting rod 53 and the limiting member 5 are fixed or integrally set. This setting can stably fix the limiting member 5 on the base frame 1. When the corresponding limiting rod 41 abuts against the limiting end 51, part of the force on the limiting member 5 can be transferred to the base frame 1, which makes the overall support better and prevents the seat frame 2 from shaking.

[0022] Furthermore, the seat frame 2 is equipped with a flexible guide rail 6. The seat frame 2 includes a backrest 21 and a seat 22 that are rotatably connected. At least one set of rocker arms 4 is provided at the position corresponding to the backrest 21, and at least one set of rocker arms 4 is provided at the position corresponding to the seat 22. Specifically, two sets of rocker arms are provided on the backrest 21, and one set of rocker arms is provided on the seat 22. The two sets of limiting rods 41 are located on the backrest 21 and the seat 22, respectively. A walking massage mechanism can be installed on the flexible guide rail 6 to provide a massage effect. When the seat frame 2 is in a sitting position, the seat 22 will not rotate and open relative to the backrest 21. However, when the seat frame 2 is in a reclining position, the seat 22 will rotate and open relative to the backrest 21, allowing the overall opening range of the seat frame 2 to be larger and providing better comfort for the user.

[0023] Additionally, it includes a leg support 7 hinged to the seat backrest 2 and a leg electric push rod 8 that drives the leg support 7 to rotate. The backrest electric push rod 3 is hinged between the base frame 1 and the seat backrest 2, and the leg electric push rod 8 is hinged between the seat backrest 2 and the leg support 7. The leg support 7, driven by the leg electric push rod 8 to open or close relative to the seat backrest 2, provides better support and comfort for the user's legs.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
