The leg frame structure of the massage chair comprises an upper leg frame 1, a lower leg frame 2, a driving component and a safety switch 4, wherein the upper leg frame 1 and the lower leg frame 2 are connected in a sliding mode, and the driving component is used for driving the upper leg frame 1 and the lower leg frame 2 to slide relatively.

In order to ensure the stability of the sliding movement between the upper leg unit 1 and the lower leg unit 2, one of the upper leg unit 1 and the lower leg unit 2 is provided with a sleeve 10, and the other is provided with a rod 20, and the rod 20 is slidably disposed in the sleeve 10. In the embodiment, the upper leg frame 1 is provided with a sleeve 10, and the sleeves 10 are respectively arranged at two sides of the upper leg frame 1, and the sleeves 10 with square cross sections are adopted; the lower leg frame 2 is provided with a rod body 20, the same rod bodies 20 are respectively arranged on two sides of the lower leg frame 2, the rod bodies 20 with circular sections are adopted, the rod bodies 20 on the two sides slide in the sleeve 10, and the sliding stability is ensured while guiding.

The driving assembly comprises a telescopic driving rod 30 and a power member 31 for driving the driving rod 30 to be telescopic, wherein the driving rod 30 can be a push rod or the like, and the power member 31 can be a motor or the like. One end of the driving rod 30 is connected to the upper leg 1, and the other end of the driving rod 30 is movably connected to the lower leg 2, that is, the other end of the driving rod 30 can be displaced from the lower leg 2 by a certain distance, but the displacement distance is only small so as to trigger the safety switch 4.

As shown in fig. 1-4, the power member 31 drives the driving rod 30 to contract, and the upper leg 1 and the lower leg 2 slide relatively and approach each other; as shown in fig. 5-6: the driving rod 30 is driven by the power unit 31 to extend, the upper leg 1 and the lower leg 2 slide relatively and move away from each other, and the upper leg 1 and the lower leg 2 are continuously moved toward and away from each other during the massage.

The safety switch 4 is disposed on the lower leg frame 2 and connected to the power member 31, when the upper leg frame 1 and the lower leg frame 2 are forced to make the other end of the driving rod 30 move relative to the lower leg frame 2 and trigger the safety switch 4, the power member 31 stops providing power to the driving rod 30, and the driving rod 30 stops extending and contracting.

The following embodiment describes the structure of the lower driving rod 30 and the safety switch 4 for triggering:

in this embodiment: the lower leg frame 2 is provided with a cross bar 21, a connecting member, a transmission member, and an elastic member 24. Wherein: the connecting element is in particular connected to the cross bar 21 of the lower leg frame 2.

The connecting piece includes the curb plate 220 that is located both sides, connects the dead lever 221 between the curb plate 220 of both sides, and curb plate 220 fixed connection is on horizontal pole 21, and safety switch 4 sets up on the curb plate 220 of one side.

The transmission member includes transmission connection portions 230 at both sides, and an interference portion 231 connected between the transmission connection portions 230 at both sides, one end of the transmission connection portion 230 is rotatably connected with the other end of the driving rod 30, and the other end of the transmission connection portion 230 is rotatably connected with the fixing rod 221 on the connection member.

The elastic member 24 is wound around the fixing rod 221, and the end of the elastic member 24 abuts against the abutting portion 231 of the transmission member, and the elastic member 24 gives the elastic force to the other end of the driving lever 30 away from the safety switch 4. In this embodiment: the elastic member 24 may be, for example, a torsion spring, and the elastic member 24 presses the abutting portion 231 downward to pull the other end of the driving rod 30 away from the safety switch 4.

The other end of the driving rod 30 is provided with a connecting shaft 300, and one end of the transmission member upper transmission connecting portion 230 is rotatably connected to the connecting shaft 300. An end of the connection shaft 300 is provided with a trigger 301, and the trigger 301 may contact the safety switch 4 to trigger the safety switch 4.

The leg structure is shown in FIGS. 1-6 during normal sliding; when the upper leg frame 1 and the lower leg frame 2 are subjected to external force, for example, a foot extends between the upper leg frame 1 and the lower leg frame 2, the transmission member overcomes the torsion of the elastic member 24, so that the other end of the transmission connecting portion 230 of the transmission member rotates around the fixing rod 221, one end of the transmission connecting portion 230 of the transmission member lifts the connecting shaft 300 on the driving rod 30 upward until the trigger 301 contacts the safety switch 4 and triggers, the safety switch 4 sends a signal to the power member 31 after being triggered, the power member 31 is powered off, the driving rod 30 stops stretching, and the sliding between the upper leg frame 1 and the lower leg frame 2 stops, thereby protecting a user.

The above embodiments are only for illustrating the technical idea and features of the present invention, and the purpose of the present invention is to enable those skilled in the art to understand the content of the present invention and implement the present invention, and not to limit the protection scope of the present invention by this means. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
