Description

Technical Field

[0001] The utility model belongs to the technical field of massage chairs, in particular to a massage driving mechanism with a large kneading amplitude. Background Art

[0002] As people's living standards improve, their demand for massage is also increasing. In order to meet people's massage needs, an automatic massage chair has emerged. When a user lies on the chair, the driving structure of the massage chair drives the striking part to rotate around the axis, and the striking part contacts the user during the rotation, thereby providing knocking and squeezing functions. The massage of the massage chair is achieved by selecting striking parts of different sizes or controlling the trajectory radius of the striking part during rotation.

[0003] However, the existing striking part does not change its height or position beyond the chair surface when rotating, thereby only providing a massage experience to the user, and the kneading amplitude is small and cannot meet the needs of the user. Some massage chairs achieve different massage effects by adding multiple sets of striking parts, but this will cause the driving structure of the striking part to be complex and large in size, thereby affecting the size of the massage chair. Utility Model Content

[0004] In view of this, the utility model provides a bearing structure for a massage chair to solve the above problems.

[0005] A massage drive mechanism with a large kneading amplitude comprises a seat, a first drive assembly arranged on the seat, and a second drive assembly arranged on the seat. The first drive assembly comprises a first rotating shaft rotatably inserted on the seat, and first mounting rods respectively inserted at both ends of the first rotating shaft. An angle is formed between the axis of the first mounting rod and the axis of the first rotating shaft. The second drive assembly comprises a second rotating shaft rotatably inserted on the seat, and second mounting rods respectively inserted at both ends of the second rotating shaft. The axes of the two second mounting rods are respectively parallel to the axis of the second rotating shaft and do not overlap.

[0006] Furthermore, the angle between the first mounting rod and the first rotation axis is an acute angle.

[0007] Furthermore, the acute angle between the first mounting rod and the first rotation axis is 15°-30°.

[0008] Furthermore, the first driving assembly further includes a pulley transmission structure disposed on one side of the first rotating shaft, and the second driving assembly further includes a worm gear transmission structure disposed on one side of the second rotating shaft.

[0009] Furthermore, the seat body includes two panels arranged at an interval and a connecting plate arranged between the two panels.

[0010] Furthermore, the panel is fan-shaped, an arc-shaped rack is arranged along the arc-shaped contour of the fan on each panel, and an insertion hole is opened at the central angle of the fan on the two panels.

[0011] Furthermore, the first rotation axis and the second rotation axis are parallel to each other and spaced apart.

[0012] Further, a cross-sectional radius of the first rotating shaft is greater than a cross-sectional radius of the first mounting rod, and a side wall of the second mounting rod does not exceed a side wall of the second rotating shaft.

[0013] Compared with the prior art, the massage drive mechanism with a large kneading amplitude provided by the utility model is provided with a seat body, and a first drive component and a second drive component are arranged at intervals on the seat body to provide two massage areas. There is an angle between the first rotating shaft of the first drive component and the axis of the first mounting rod, so that the striking part can provide alternating pressing effects at two positions on the seat surface of the massage chair when it rotates, thereby increasing the massage surface and the kneading amplitude. The second rotating shaft of the second drive component and the axis of the second mounting rod are parallel to each other and arranged at intervals, thereby providing alternating pressing effects of different intensities on the massage surface to enrich the user's massage experience and increase the kneading amplitude, and there is no need to add multiple sets of drive structures, saving space.

[0017] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0018] like Figures 1 to 3As shown, it is a schematic diagram of the structure of the massage drive mechanism with a large kneading range provided by the utility model. The drive structure of the massage chair includes a seat body 10, a first drive assembly 20 arranged on the seat body 10, and a second drive assembly 30 arranged on the seat body 10. The massage drive mechanism with a large kneading range also includes some other functional modules, such as motors arranged on one side of the first drive assembly 20 and the second drive assembly 30, etc., which should be well known to those skilled in the art and will not be described in detail one by one here.

[0019] The seat body 10 includes two panels 11 spaced apart from each other, a connecting plate 12 disposed between the two panels 11 , arc-shaped racks 13 disposed on the two panels 11 , and insertion holes 14 disposed on the two panels 11 .

[0020] The panel 11 is used to install the worm gear transmission structure 20 and the pulley transmission structure 30. The panel 11 is fan-shaped.

[0021] The connecting plate 12 is used to support the two panels 11. The arc-shaped rack 13 is arranged at the arc-shaped edge of the panel 11. The insertion hole 14 is arranged at the center of the sector of the panel 11. A rotating pin is inserted in the insertion hole 14. The seat body 10 rotates along the rotating pin.

[0022] The arc-shaped rack 13 will mesh with the gear structure in the massage chair to move in a controlled manner, thereby driving the panel 11 to rotate around the rotating pin. The rotating pin is not marked in the figure.

[0023] The first driving assembly 20 includes a first rotating shaft 21 rotatably inserted between the two panels 11 , first mounting rods 22 obliquely inserted at both ends of the first rotating shaft 21 , and a worm gear driving assembly 23 disposed between the two panels 11 .

[0024] The first rotating shaft 21 is used to drive the first mounting rod 22 to rotate. The cross-sectional radius of the first rotating shaft 21 is greater than the cross-sectional radius of the first mounting rod 22.

[0025] A first striking part for installing a massage chair is respectively installed at both ends of the first mounting rod 22. The first striking part is a hard sphere or a nearly sphere covered with sponge. It should be noted that the shape and structure of the first striking part are well known to those skilled in the art and are not the main content of the utility model, so they are not described here and are not shown in the figure. There is an acute angle between the axis of the first mounting rod 22 and the axis of the first rotating shaft 21. The angle between the axis of the first mounting rod 22 and the axis of the first rotating shaft 21 is 15°-30° to avoid the angle being too large to affect the force at the connection between the first rotating shaft 21 and the first mounting rod 22. When the first mounting rod 22 rotates, the striking part arranged at the end of the first mounting rod 22 can obtain a larger rotation radius, so that a larger striking range can be obtained without changing the size and installation position of the striking part.

[0026] The turbine drive assembly 23 includes a worm housing 231 disposed between the two panels 11, a worm 232 rotatably inserted in the worm housing 231, and a worm wheel 233 fixedly sleeved on the first rotating shaft 21. The worm 232 is meshed with the worm wheel 233, so that the worm wheel 233 can be driven to rotate by driving the worm 232, thereby driving the first rotating shaft 21 to rotate.

[0027] The second driving assembly 30 includes a second rotating shaft 31 rotatably inserted between the two panels 11 , second mounting rods 33 eccentrically inserted at both ends of the second rotating shaft 32 , and a pulley transmission assembly 33 arranged between the two panels 11 .

[0028] The second rotating shaft 31 is parallel to and spaced apart from the first rotating shaft 21. The second rotating shaft 31 is used to drive the second mounting rod 33 to rotate.

[0029] A second striking portion is respectively installed at both ends of the second mounting rod 33. The second striking portion has the same structure as the first striking portion, which will not be described in detail and is not shown in the figure.

[0030] The axis of the second installation rod 33 does not coincide with the axis of the second rotating rod 31 , so that the second installation rod 33 can obtain a larger movement range when the second rotating rod 31 rotates.

[0031] The cross-sectional radius of the second rotating rod 31 is greater than the cross-sectional radius of the second mounting rod 33 , and the outer side wall of the second mounting rod 33 does not exceed the outer side wall of the second rotating rod 31 .

[0032] The pulley transmission assembly 33 includes a pulley 331 mounted on the second rotating shaft 31, and a transmission belt 332 mounted on the pulley 331. The transmission belt 332 is mounted on an external driving shaft, and the driving shaft rotates to drive the transmission belt 332 to rotate. The driving shaft is not shown in the figure.

[0033] Compared with the prior art, the massage drive mechanism with a large kneading amplitude provided by the utility model is provided with a seat body 10, and a first drive component 20 and a second drive component 30 are arranged at intervals on the seat body 10 to provide two massage areas. There is an angle between the first rotating shaft 21 of the first drive component 20 and the axis of the first mounting rod 22, so that when the striking part rotates, it can provide alternating pressing effects at two positions on the seat surface of the massage chair, thereby increasing the massage surface and the kneading amplitude. The second rotating shaft 31 and the axis of the second mounting rod 32 of the second drive component 30 are parallel to each other and arranged at intervals, so as to provide alternating pressing effects of different intensities on the massage surface, so as to enrich the user's massage experience and increase the kneading amplitude, and there is no need to add multiple sets of driving structures, thus saving space.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
