Description

Technical Field

[0001] This utility model relates to the field of massage chair technology, specifically to an elastic steel strip that facilitates the passage of robotic arms and has an anti-slip effect. Background Technology

[0002] With the continuous advancement of technology, massage chairs will be designed and functionally more advanced to better serve people's daily lives. Massage chairs have evolved from the initial sitting function to the backrest function, and then to the "zero gravity" reclining function. The development of massage chairs that can be laid flat like a bed is to provide a more comfortable and personalized massage experience, that is, to achieve the effect of "extreme relaxation" on the massage chair.

[0003] The present invention application, number 202111620325.6, relates to a flattenable massage chair with an involute toothed chain track that facilitates robotic arm movement. The chair includes a backrest frame, a seat frame, and a robotic arm. The backrest frame is mounted on the seat frame. The chair also includes a toothed chain, with one end mounted on the backrest frame and the other end mounted on the seat frame. The toothed chain comprises several chain tooth plates, each with two toothed portions at its head and tail. The head and tail teeth of adjacent chain tooth plates along the length of the toothed chain are staggered and hinged together. The robotic arm is equipped with a sprocket that meshes with the toothed chain. By adopting this design, constant pitch meshing of the sprocket and the toothed chain can be achieved, resulting in more stable robotic arm operation. The chair features a simple structure, high torque transmission, and good noise reduction.

[0004] The aforementioned application may result in tooth slippage or longitudinal jumping when the robotic arm passes through the chain. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an elastic steel strip pressure bar that can effectively prevent the robot arm from falling off or skipping teeth, ensure that the robot arm can pass smoothly through the chain, and prevent the robot arm from moving longitudinally.

[0006] To achieve the above objectives, the following technical solution is adopted: an elastic steel strip pressure bar that facilitates the passage of a robotic arm and has an anti-slip effect, comprising a backrest frame, a seat frame, and a robotic arm. The backrest frame is mounted on the seat frame, and backrest frame guide rails are provided on both sides of the backrest frame. Seat frame guide rails are provided on both sides of the seat frame. A flexible guide rail connects the backrest frame guide rails and the seat frame guide rails. When the backrest frame is upright or reclined on the seat frame, the flexible guide rails bend or stop bending. The robotic arm is equipped with a traveling gear, which moves on the backrest frame guide rails, seat frame guide rails, or flexible guide rails through tooth meshing. The end of the backrest frame guide rail facing the seat frame guide rail... An elastic steel strip pressure bar is also provided above the flexible guide rail to prevent the walking gear from moving longitudinally. The upper side of the elastic steel strip pressure bar is provided with a winding cylinder, and the lower side of the elastic steel strip pressure bar is provided with a transition plate. When the backrest is upright on the seat frame, the transition plate presses down and bends the lower side wall of the elastic steel strip pressure bar, and the upper side wall of the elastic steel strip pressure bar bends and abuts against the side wall of the winding cylinder. When the backrest is reclined on the seat frame, the transition plate stops bending the elastic steel strip pressure bar, and the elastic steel strip pressure bar returns to its initial state. When the walking gear is located on the flexible guide rail, the elastic steel strip pressure bar elastically abuts against the upper part of the walking gear to prevent the robot arm from moving longitudinally.

[0007] Using the above technical solution, the flexible guide rail is an elastic rack and pinion chain similar to that in the prior art, with an elastic substrate at its lower end. When the elastic steel strip pressure bar is not provided, the robot's walking gear moves on the bent flexible guide rail. Typically, a baffle can be installed on the backrest guide rail to prevent the robot from jutting out longitudinally. However, the baffle does not have elastic deformation capability. Therefore, even with a baffle above the flexible guide rail, the robot is prone to longitudinal movement, leading to a loss of movement. The elastic steel strip pressure bar, however, can bend or stop bending as the backrest stands up or lies down. Because the elastic steel strip pressure bar is elastic, and due to the inclusion of a winding cylinder and transition plate, when the backrest stands up... At startup, the transition plate presses one end of the elastic steel strip upwards and lifts it up, while the middle of the elastic steel strip abuts against the side wall of the winding cylinder. This allows it to bend at two points and achieve the same bending shape as the toothed chain, and it can correspond exactly to the position above the toothed chain. When the robot moves longitudinally, the elastic steel strip can elastically abut against the upper end of the robot's traveling gear, thereby preventing the traveling gear from moving longitudinally. Due to the robot's own weight and the pressure exerted on it by the human body, the downward pressure value of the elastic steel strip is not very large. Therefore, the elastic steel strip can elastically abut against the upper end of the robot's traveling gear, thereby preventing the robot from moving longitudinally.

[0008] An elastic steel strip pressure bar that facilitates the passage of robotic arms and has an anti-slip effect can be further configured as follows: one end of the elastic steel strip pressure bar is a fixed end, which is fixed to the backrest frame guide rail; the other end is a bent end, the bent end is in the shape of a rope buckle and has clearance grooves penetrating on the upper and lower sides, the transition plate includes a base frame fixed to the backrest frame guide rail, a tongue plate is fixed on the base frame, and the tongue plate extends into the clearance groove to prevent the elastic steel strip pressure bar from swinging laterally.

[0009] Using the above technical solution, the two sides of the traveling gear are spur gears, and the two spur gears are sprocket gears. When the traveling gear transitions from the backrest frame guide rail or seat frame guide rail to the flexible guide rail, the design of the tongue plate and the clearance groove allows the sprocket gear to achieve a clearance effect when passing the elastic steel belt hanging plate. At the same time, it also prevents the tongue plate from lateral swaying when pressing the elastic steel belt pressure strip, making the deformation of the elastic steel belt hanging plate more stable.

[0010] An elastic steel strip pressure bar that facilitates the passage of robotic arms and has an anti-slip effect can be further configured as follows: a positioning pin is provided through the tongue plate, the two ends of the positioning pin protrude from both sides of the tongue plate and abut against the lower side wall of the elastic steel strip pressure bar, and positioning blocks are also provided on both sides of the tongue plate, with the positioning blocks and positioning pins abutting against the lower side wall of the elastic steel strip pressure bar.

[0011] With the above technical solution, if no positioning pin is set, the tongue plate will be fully inserted into the clearance groove. The positioning pin and positioning block are used to abut against the lower side wall of the elastic steel strip, so that when the backrest frame is upright, the elastic steel strip can be deformed by the positioning pin and positioning block, and the structure is reasonable.

[0012] An elastic steel strip pressure bar that facilitates the passage of robotic arms and has an anti-slip effect can be further configured as follows: the winding cylinder is fixedly installed on the side of the backrest frame guide rail, and the end of the winding cylinder away from the backrest frame guide rail is provided with a pressure bar anti-slip plate to prevent the elastic steel strip pressure bar from slipping out.

[0013] Using the above technical solution, the winding cylinder is fixed to the side of the backrest frame guide rail, thereby enabling it to resist the upper side of the elastic steel strip pressure bar. The pressure bar anti-slip plate can prevent the elastic steel strip pressure bar from sliding away from the backrest frame guide rail when it is pressed up, thereby increasing the stability of the elastic steel strip pressure bar during deformation.

[0024] 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.

[0025] Example: Figures 1-8The illustration shows an elastic steel strip pressure bar that facilitates the passage of a robotic arm and has an anti-slip effect. It includes a backrest frame 1, a seat frame 2, and a robotic arm 3. The backrest frame 1 is mounted on the seat frame 2. Backrest frame guide rails 11 are provided on both sides of the backrest frame 1, and seat frame guide rails 21 are provided on both sides of the seat frame 2. A flexible guide rail 31 connects the backrest frame guide rails 11 and the seat frame guide rails 21. The flexible guide rail 31 is an elastic rack and pinion chain similar to that in the prior art, with an elastic substrate at its lower end. The backrest frame 1 can be raised or lowered onto the seat frame 2, causing the flexible guide rail 31 to bend or stop bending. The robotic arm 3 is equipped with a traveling gear 5, which moves along the backrest frame guide rails 11, seat frame guide rails 21, or flexible guide rails 31 through tooth meshing. Figures 4-8 As shown, the backrest guide rail 11 facing the seat guide rail 21 is also provided with an elastic steel strip 6 located above the flexible guide rail 31 to prevent the walking gear 5 from moving longitudinally. When the elastic steel strip 6 is not provided, when the walking gear 5 of the robot arm 3 moves on the bent flexible guide rail, the backrest guide rail 11 can usually be equipped with a baffle to prevent the robot arm 3 from moving longitudinally. However, the baffle does not have elastic deformation capability. Therefore, even if a baffle is provided above the flexible guide rail 31, the robot arm 3 is prone to moving longitudinally and becoming unable to move. The elastic steel strip 6 can achieve the same effect as the backrest 1 is upright or reclined. Figure 7 The bend shown or as Figure 8The bending stop shown is achieved because the elastic steel strip 6 is elastic. One end of the elastic steel strip 6 is a fixed end 61, which is fixed to the backrest frame guide rail 11; the other end is a bending end 62, which is rope-shaped and has relief grooves 63 penetrating on the upper and lower sides. A transition plate 64 is provided on the lower side of the elastic steel strip 6. The transition plate 64 presses down on and bends the lower side wall of the elastic steel strip 6. The transition plate 64 includes a base frame 641 fixed to the backrest frame guide rail 11. A tongue plate 642 is fixed on the base frame 641. A positioning pin 643 passes through the tongue plate 642. The two ends of the tongue plate 642 protrude from both sides and abut against the lower side wall of the elastic steel strip pressure strip 6. Positioning blocks 644 are also provided on both sides of the tongue plate 642. Both positioning blocks 644 and positioning pins 643 abut against the lower side wall of the elastic steel strip pressure strip 6. The tongue plate 642 is fixedly mounted on the base frame 641. The tongue plate 642 extends into the relief groove 63 to prevent the elastic steel strip pressure strip 6 from swinging laterally. A winding cylinder 65 is provided on the upper side of the elastic steel strip pressure strip 6. The winding cylinder 65 is fixedly mounted on the side of the backrest frame guide rail 11. A pressure strip anti-slip plate is provided at the end of the winding cylinder 65 away from the backrest frame guide rail 11 to prevent the elastic steel strip pressure strip 6 from slipping out. 651, when the backrest frame is erected on the seat frame, the upper side wall of the elastic steel strip 6 bends and abuts against the side wall of the winding cylinder 65; when the backrest frame 1 is erected on the seat frame 2, the transition plate 64 stops bending the elastic steel strip 6, and the elastic steel strip 6 returns to its initial state. When the traveling gear 5 is located on the flexible guide rail 31, the elastic steel strip 6 elastically abuts against the upper part of the traveling gear 5 to prevent the robot arm 3 from moving longitudinally. Due to the setting of the winding cylinder 65 and the transition plate 64, when the backrest frame 1 is erected, the transition plate 54 presses one end of the elastic steel strip 6 upward and tilts it up, while the middle part of the elastic steel strip 6 is... The side wall of the winding cylinder 65 abuts against the flexible guide rail 31, so that the two-point bending can be the same as the bending shape of the flexible guide rail 31, and can be exactly corresponding to the position above the flexible guide rail 31. When the robot arm 3 moves longitudinally, the elastic steel strip 6 can elastically abut against the upper end of the walking gear 5 of the robot arm 3, thereby preventing the walking gear 5 from moving longitudinally. Due to the weight of the robot arm 3 itself and the pressure of the human body on it, the downward pressure value of the elastic steel strip 6 is not very large. Therefore, the elastic steel strip 6 can elastically abut against the upper part of the walking gear 5 of the robot arm 3, thereby preventing the robot arm 3 from moving longitudinally.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
