Description

Technical Field

[0001] The utility model relates to the technical field of massage equipment, in particular to a 3D implementation structure of a thin movement push rod. Background Art

[0002] The massage movement is an important component of the massage chair, and is also commonly known as the massage manipulator in the industry. With the development of the massage chair industry, the massage movement is driven by the extension and retraction of the electric push rod to achieve the ejection and retraction actions, thereby achieving a 3D massage effect.

[0003] However, in order to complete the movement of ejecting and retracting the movement, most 3D massage movements nowadays use motor-driven gears to make the massage movement move up and down. For example, a 3D massage movement with application number 202111455859.8 includes a movement body, a driving wheel shaft, a driven wheel shaft and a walking power device; the driving wheel shaft and the driven wheel shaft are separated at both ends of the movement body, and travel on two tracks with the help of rollers positioned on the driving wheel shaft and the driven wheel shaft; the driving wheel shaft, which is transmission-connected to the walking power device, is also locked with a gear, and meshes with the rack on the track, driving the movement body to reciprocate along the track; wherein: the driven wheel shaft is rotatably hinged to the movement body through a support arm, and an electric push rod is arranged between the movement body and the support arm, and the electric push rod drives the support arm to swing, thereby changing the position difference between the driven wheel shaft and the driving wheel shaft, thereby driving the movement body to eject and retract, and its structure is relatively complex. Utility Model Content

[0004] The purpose of the utility model is to provide a 3D implementation structure of a thin movement push rod in order to solve the above-mentioned problem.

[0005] The technical solution of the utility model is achieved in this way:

[0006] The utility model provides a 3D implementation structure of a thin movement push rod, comprising an upper frame, a lower frame and a movement body, one end of the upper frame is hinged to the lower frame, and the movement body is fixedly installed on the upper frame, and the lower frame is provided with a pushing device to enable the opening and closing end of the upper frame to rotate within a preset angle α.

[0007] In one embodiment, the pushing device is an electric push rod, a first end of the electric push rod is hinged to the closed end of the lower frame, and a second end of the electric push rod is hinged to the open end of the upper frame;

[0008] When the electric push rod is in the retracted state, an angle is formed with a side of the lower frame close to the upper frame.

[0009] In one embodiment, the first end of the electric push rod is a power end, and the second end of the electric push rod is a support end.

[0010] In one embodiment, the lower frame is fixedly provided with a support for hingedly connecting the power end of the electric push rod, and one end of the support connected to the electric push rod extends toward the middle of the lower frame.

[0011] In one implementation, the preset angle α ranges from 0° to 30°.

[0012] In one embodiment, the movement body includes a driving component and a massage component;

[0013] The driving assembly comprises a driving member and a power member, and the power member is connected to the driving member through a driving support arm;

[0014] The massage component comprises a swing arm arranged on the driving member, the swing arm is in a V-shaped structure, and massage wheels are connected to both tips of the swing arm.

[0015] The advantages or beneficial effects of the above technical solution include at least:

[0016] First, in the utility model, the electric push rod itself is placed at an angle. When the electric push rod is extended, the opening and closing end of the upper frame can be pushed upward, so that the upper frame is flipped upward with the hinge with the lower frame as the fulcrum, driving the movement body to be ejected. When the electric push rod is contracted, it drives the upper frame to flip downward, driving the movement body to be retracted. The movement body can be ejected and retracted only by the extension and retraction of the electric push rod.

[0017] Secondly, in the utility model, the support end of the electric push rod is hinged to the upper frame, and the power end is hinged to the lower frame, so as to reduce the load on the electric push rod during the extension and retraction process, strengthen the supporting force of the electric push rod on the upper frame, and enable the electric push rod to push the upper frame to flip more stably.

[0018] Third, in the utility model, the extension and retraction stroke of the electric push rod is reduced by setting the support, ensuring that the electric push rod can stably play the role of flipping the upper frame. At the same time, the inclination angle of the electric push rod is increased, so that the upper frame can be lifted to a greater height when the electric push rod is extended, thereby enhancing the ejection effect of the movement body.

[0019] Fourthly, in the present invention, the rotation angle of the upper frame is limited. When the electric push rod is extended to the maximum length, the upper frame rotates to the maximum angle of 30° to prevent the movement body from breaking the massage chair.

[0020] Fifth, the utility model has a simple structure and a lower cost than the prior art, can effectively reduce the failure rate, and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The names of the messages or information exchanged between multiple devices in the implementation manner of the present utility model are only used for illustrative purposes, and are not used to limit the scope of these messages or information.

[0034] Reference Figure 1-Figure 4 , a thin movement push rod 3D implementation structure, including an upper frame 1, a lower frame 2 and a movement body 3, one end of the upper frame 1 is hinged to the lower frame 2, and the movement body 3 is fixedly installed on the upper frame 1, and the lower frame 2 is provided with a pushing device to enable the opening and closing end of the upper frame 1 to rotate within the range of a preset angle α. Under such a setting, when the movement body 3 is ejected and retracted, the pushing device lifts the opening and closing end of the upper frame 1, so that the upper frame 1 is turned outward with the hinge with the lower frame 2 as the fulcrum, thereby driving the movement body 3 to be ejected, and when the pushing device is retracted, it drives the upper frame 1 to turn inward to drive the movement body 3 to be retracted.

[0035] Reference Figure 1 and Figure 3Specifically, the pushing device is an electric push rod 4, a first end of the electric push rod 4 is hinged to the closed end of the lower frame 2, and a second end is hinged to the open and close end of the upper frame 1. When the electric push rod 4 is in a retracted state, an angle is formed with the side of the lower frame 2 close to the upper frame 1, and the opening of this angle faces the open and close end of the upper frame 1. When the electric push rod 4 is extended, its pushing force on the open and close end of the upper frame 1 is converted into an upward and forward force after force analysis. Since the closed end of the upper frame 1 is hinged to the lower frame 2, only the upward force can take effect, so that the upper frame 1 is flipped upward with the closed end as the fulcrum. At the same time, because the two ends of the electric push rod 4 are respectively hinged to the upper frame 1 and the lower frame 2, when the upper frame 1 is flipped, the electric push rod 4 is also flipped with the connection with the lower frame 2 as the fulcrum, that is, the angle formed by the electric push rod 4 and the lower frame 2 increases. In a specific embodiment, the angle formed by the electric push rod 4 and the lower frame 2 is always an acute angle.

[0036] In a specific embodiment, the preset angle α ranges from 0° to 30°, that is, when the electric push rod 4 is extended to the maximum length, the angle formed by the hinge between the upper frame 1 and the lower frame 2 is 30°, which prevents the upper frame 1 from rotating too much and causing the movement body 3 to pierce the skin of the massage chair.

[0037] Reference Figure 3 In a specific embodiment, the first end of the electric push rod 4 is the power end, and the second end is the support end. In this configuration, the power end is hinged to the lower frame 2 so that the power end can only perform relative rotational movement with the lower frame 2. When the electric push rod 4 is extended, the support end extends outward against the opening and closing end of the upper frame 1.

[0038] Reference Figure 6 In another specific embodiment, the first end of the electric push rod 4 is the support end, and the second end is the power end. In this configuration, the support end is hinged to the lower frame 2, and when the electric push rod 4 is extended, the power end pushes against the opening and closing end of the upper frame 1 and extends outward.

[0039] In the electric push rod 4, the support end is a thick and long rod, and the power end is a thin and long rod. Therefore, the support end can bear a larger external load than the power end. Therefore, during use, the support end of the electric push rod 4 moves against the upper frame 1, which is less likely to cause structural instability than the power end moving against the upper frame 1, thereby improving the durability of the electric push rod 4. Therefore, as a preferred embodiment, the present invention adopts a method in which the support end of the electric push rod 4 is hinged to the opening and closing end of the upper frame 1 and the power end is hinged to the lower frame 2, so that the movement of the electric push rod 4 is more stable and its service life is extended. However, the method in which the power end of the electric push rod 4 is connected to the opening and closing end of the upper frame 1 and the support end is connected to the lower frame 2 in another embodiment also belongs to the protection scope of the present invention.

[0040] Reference Figure 2 and Figure 4 The lower frame 2 is fixed with a support 5 for articulating the power end of the electric push rod 4, and one end of the support 5 connected to the electric push rod 4 extends to the middle part of the lower frame 2. With this arrangement, the telescopic stroke of the electric push rod 4 is reduced, and the angle formed by the electric push rod 4 and the lower frame 2 is increased, so that the electric push rod 4 only needs to move a smaller stroke when lifting the opening and closing end of the upper frame 1 to the maximum opening and closing angle, thereby reducing the rod length of the electric push rod 4, that is, further reducing the probability of structural instability of the electric push rod 4 during use.

[0041] In summary, in the present invention, the movement body 3 can be pushed out and retracted only by the extension and retraction of the electric push rod 4, and the structure is simpler.

[0042] Reference Figure 5 The movement body 3 includes a driving assembly 31 and a massage assembly 32, wherein the driving assembly 31 includes a driving member 311 and a power member 312, the power member 312 is connected to the driving member 311 through a driving arm 313, and the massage assembly 32 includes a swing arm 321 arranged on the driving member 311. During use, when the upper frame 1 is opened and closed, the power member 312 rotates synchronously and drives the driving member 311 to move through the driving arm 313, so that the swing arm 321 moves up and down. The rear displacement activity is combined to realize the 3D effect of the movement. Preferably, the swing arm 321 is in a V-shaped structure, and the two tip ends of the swing arm 321 are connected with massage wheels 322. In this way, the massage wheels 322 can increase the force area between the movement body 3 and the human body, reduce the pressure of the movement body 3 on the human body, and avoid the protrusion of the swing arm 321 directly pressing on the human body and accidentally causing damage to the human body. In addition, the massage wheels 322 can rotate on their own so that the movement body 3 can move up and down more smoothly when pressing on the human body.

For those skilled in the art, other changes or modifications may be made based on the above disclosure, and these changes or modifications are still within the scope of the present invention.
