Description

Technical Field

[0001] The utility model relates to the technical field of massage chairs, in particular to a pull rod arm manipulator with an air bag lifting plate. Background Art

[0002] Most of the single-movement or dual-movement massage chairs currently on the market use movements that focus on upper body massage, but are not comfortable for lower body massage. The lower body massage area is the buttocks and thighs. The characteristic of the buttocks is that the body weight presses down, the tension is large, and the massage is not easy to go deep, so a large force is required; the characteristic of the thigh area is that the load-bearing area is tight, so it is difficult for the massage head to extend, while the other parts of the thigh are lighter in weight, and are affected by individual differences and sitting postures, making it difficult to find the correct massage position, and the massage effect is difficult to meet the requirements. For this reason, a lower body massage movement is needed. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a mechanical hand which can massage the lower body and can be lifted up and down and swung left and right by an air bag for massage in view of the deficiencies of the prior art.

[0004] To achieve the above-mentioned purpose, the following technical scheme is adopted: a pull rod arm manipulator with an airbag lifting plate, comprising a support plate, a driving motor and a kneading component, wherein the driving motor drives the kneading component, the kneading component comprises a first kneading component and a second kneading component, the first kneading component comprises a first kneading shaft, the first kneading shaft is provided with two first oblique seats, each of the first oblique seats is provided with a first kneading arm outside, the second kneading component comprises a second kneading shaft, the second kneading shaft is parallel to the first kneading shaft and is connected to the first kneading shaft through a gear set, the second kneading shaft is provided with two second oblique seats, each of the second oblique seats is provided with a second kneading arm outside, the spacing between the first kneading arms on the first kneading shaft is greater than the spacing between the second kneading arms on the second kneading shaft, and the first kneading arm and the second kneading arm are located on the same axis or are staggered front and back on the support plate.

[0005] By adopting the above technical solution, since the spacing between the first kneading arms on the first kneading shaft is greater than the spacing between the second kneading arms on the first kneading shaft, when the first kneading assembly and the second kneading assembly are staggered up and down, the massage directions of the first kneading assembly and the second kneading assembly can be opposite, when the first kneading arm of the first kneading assembly is in a clamping action, the second kneading arm of the second kneading assembly can be in a relaxing action; when the first kneading arm of the first kneading assembly is in a clamping action, the second kneading arm of the second kneading assembly can be in a relaxing action, the arrangement state of the first kneading arm and the second kneading arm is: when the first kneading arm is relaxed, the second kneading arm is clamped, and at this time the arrangement shape of the two groups of kneading arms is It is similar to an "M" shape with a small gap in the middle and large gaps at both ends; when the first kneading arm is clamped and the second kneading arm is relaxed, the arrangement shape of the two groups of kneading arms is similar to two separated "V" shapes. The motor can make the oblique seat reverse forward and reverse through forward and reverse rotation, so that the arrangement shape of the two groups of kneading arms is repeatedly changed. The gear set can be set into a group of 3 so that when the first oblique seat rotates, the second oblique seat rotates in the same direction. The inclination directions of the first oblique seat and the second oblique seat are set in opposite directions. When the first kneading arm and the second kneading arm are staggered front and back, the first kneading arm can massage the waist and the second kneading arm can massage the buttocks, with a larger massage area. The oblique seat can make the first kneading arm and the second kneading arm rotate in the same direction. The two kneading arms perform kneading massage by gradually clamping from the outside to the inside, and the massage clamping and placing sequences of the two groups of kneading arms are different, so that when the two kneading shafts rotate, the massage technique of clamping up and lowering or clamping up and lowering can be realized, and the massage is more comfortable. At the same time, return torsion springs can be set on the first kneading arm and the second kneading arm, so that the massage arms can be extended even when they are subjected to greater tension on the lower body to find the correct massage position; when the two groups of kneading arms are on the same axis, the installation method of the second kneading arm is opposite to the previous installation method, and the gear set can be set into a group of 2 so that the rotation directions of the first oblique center seat and the second oblique center seat are opposite, and when the first kneading arm is released, the second kneading arm is also released. The first kneading shaft is in a loose state, so that the massage parts of the lower body can be massaged inside and outside at the same time, for example, the lower part of the buttocks and both sides of the buttocks can be massaged at the same time. The driving motor first drives the first kneading shaft, and the first kneading shaft then rotates the second kneading shaft through the gear set, thereby reducing the driving mechanism. At the same time, the positive and reverse rotation of the gear set can also change the massage direction of the kneading arm and can reduce the overall weight of the product. The first kneading arm and the second kneading arm can be rotatably connected with the support plate through a double ball head connecting rod to realize the clamping and kneading of the first kneading arm and the second kneading arm. A walking component can also be set on the back of the support plate, and the support plate can move up and down along the massage chair track through the walking component, so as to realize massage from top to bottom or from bottom to top.

[0006] A pull-rod arm manipulator with an airbag lifting plate can be further configured as follows: a lifting mechanism is provided between the kneading component and the support plate, the lifting mechanism includes a lifting plate and an airbag provided between the lifting plate and the support plate, the driving motor, the first kneading component and the second kneading component are all provided on the side of the lifting plate away from the airbag, and the airbag is extended and retracted to enable the lifting plate to be lifted and lowered.

[0007] By adopting the above technical solution, when the airbag expands, the lifting plate can be lifted, and the lifting plate thereby lifts the first kneading component and the second kneading component, thereby lifting the kneading component, so that the kneading component can be extended and massage the lower body of the human body.

[0008] A pull-rod arm manipulator with an airbag lifting plate can be further configured as follows: a pallet rotating frame is also provided between the pallet and the lifting plate, the pallet rotating frame is rotatably provided on the pallet, a lifting opening is provided in the pallet rotating frame, and a guide protrusion is provided on the lifting plate, the guide protrusion extends into the lifting opening to achieve guiding sliding cooperation with the inner wall of the lifting opening, and when the lifting plate is subjected to external force, the cooperation between the guide protrusion and the pallet rotating frame realizes tilting and swinging between the pallet and the lifting plate.

[0009] By adopting the above technical scheme, the lifting plate can be provided with a guide protrusion extending into the lifting port so as to realize the sliding cooperation between the guide protrusion and the inner wall of the lifting port, so that the airbag can only play the role of lifting the lifting plate, and the airbag is arranged around the outer circumference of the support plate rotating frame. When the airbag is inflated, the lifting plate will be tilted due to people with different sitting postures and weights sitting on the lifting plate. When the lifting plate is subjected to the inclined external pressure, the guide protrusion can be cooperated with the support plate rotating frame to realize the inclined swing between the lifting plate and the support plate, and the inflation of the airbag can make the guide protrusion gradually rise from the lifting port, and when the airbag is deflated, the guide protrusion on the lifting plate gradually drops from the lifting port due to the dead weight of the human body, thereby realizing the lifting and lowering of the lifting plate, and because the guide protrusion of the lifting plate is always in sliding cooperation with the lifting port, even if the airbag is not inflated, the lifting plate can be subjected to the inclined tension. The cooperation between the guide protrusion and the support plate rotating frame can realize the inclined swing between the lifting plate and the support plate.

[0010] A pull-rod arm manipulator with an airbag lifting plate can be further configured as follows: a cavity is provided on one end of the guide protrusion facing the lifting port, the drive motor is placed in the cavity, at least two notches are provided on the lifting plate, and at least two lifting blocks are provided on one end of the support plate rotating frame facing the lifting plate, and the lifting blocks extend from the notches when the airbag retracts the lifting plate.

[0011] By adopting the above technical solution, the body of the driving motor can be installed at the bottom of the lifting plate, and the guide protrusion can be provided with a cavity so as to cover the outside of the driving motor, thereby protecting the driving motor. When the airbag is in an uninflated state, most of the lifting block is exposed from the notch, and when the airbag expands and pushes up the lifting plate, the lifting block retracts from the notch. The lifting block is arranged close to the guide protrusion, thereby achieving a stabilizing effect. At the same time, since only the lifting block is extended, a larger area can be reserved on the lifting plate to install the kneading component.

[0012] A pull rod arm manipulator with an airbag lifting plate can be further configured as follows: the lifting port is located between two lifting blocks, the two lifting blocks are provided with a slide groove extending into the lifting port on opposite sides, and the guide protrusion is provided with a slider at both ends of the slide groove, the slider has the same shape as the slide groove and provides sliding cooperation between the guide protrusion and the lifting port.

[0013] By adopting the above technical solution, the shapes of the slider and the slide groove can be set to a trapezoid, so that the guide protrusion is not easy to deviate and slip when the guide sliding cooperation with the lifting port is carried out, thereby making the guide sliding of the guide protrusion and the lifting port more stable.
