Description

Technical Field

[0001] This utility model relates to a massage chair. Background Technology

[0002] With the improvement of living standards, the demand for massage chairs is increasing, and the functional requirements for massage chairs are also becoming more demanding. Massage chairs can generally massage various parts of the body, such as the arms, neck, shoulders, back, waist, buttocks, thighs, calves, and soles of the feet. However, for the arms, existing massage chairs can only provide a static massage and cannot allow the arms to swing and thus move the joints. To solve this problem, invention patent CN117677366A discloses a massage device with a rotatable arm massage part. The arm massage part of this massage device is used to accommodate the arm, and by rotating the arm massage part, the arm can be moved, thereby activating the arm joints and relaxing the arm. However, this massage device mounts both the arm massage unit and the arm rotation actuator that drives the arm massage unit on the main frame. This presents several problems: 1. It requires mounting positions on the main frame to allow the arm massage unit to rotate, increasing the complexity of the main frame; 2. Space must be left between the rotation point of the arm massage unit and the armrest to allow the rotation point of the arm massage unit to move. This results in the transmission structure and actuator being exposed, affecting aesthetics and posing a safety hazard. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, this utility model innovatively provides a massage chair with a more reasonable structure and more reasonable use.

[0004] This massage chair includes a main frame and an armrest frame, the armrest frame being installed on the side of the main frame. The armrest frame is characterized by having an arm swing member that can swing up and down, the arm swing member having a place to accommodate the arm, the place to accommodate the arm swing member being located above the armrest frame, and a power source installed inside the armrest frame, the power source driving the arm swing member to swing up and down.

[0005] The arm swinging component is rotatably mounted on the handrail frame via a rotating shaft, and the power source is connected to the rotating shaft via a transmission assembly located inside the handrail frame.

[0006] The power source is an actuator, and the transmission assembly includes a transmission rod and a connecting arm. One end of the connecting arm is connected to a rotating shaft, and the other end of the connecting arm is hinged to one end of the transmission rod. The other end of the transmission rod is connected to the telescopic rod of the actuator.

[0007] The power source is an electric motor, and the transmission assembly includes a first synchronous pulley, a second synchronous pulley, and a synchronous belt. The first synchronous pulley is connected to a rotating shaft, the second synchronous pulley is connected to the output shaft of the motor, and the synchronous belt is wound around the first and second synchronous pulleys.

[0008] An anti-pinch signal source is provided on the upper surface of the arm swing member of the handrail frame. The anti-pinch signal source is electrically connected to the controller, which can control the power source to work.

[0009] The anti-pinch signal source is an infrared sensor, a contact sensor, a light sensor, or a capacitive touch sensor.

[0010] The arm swing member has an arm massage mechanism at the arm resting position.

[0011] According to the present invention, a massage chair is provided in which the arm swinging component is rotatably mounted on the armrest frame, eliminating the need to provide space for the arm massage component to move, avoiding the exposure of the transmission structure, resulting in a more aesthetically pleasing appearance and a safer structure.

[0014] Figure 3 This is a schematic diagram of the internal transmission of this utility model. Detailed Implementation

[0015] like Figure 1 As shown, this massage chair includes a main frame 1 and an armrest frame 2. The main frame 1 is used to install the armrest frame 2 and the main body of the leg massage unit 5, and is generally made of a metal frame. The armrest frame 2 is installed on the side of the main frame 1. In order to allow for arm swinging and stretching, arm swinging components 3 that can swing up and down are installed on the armrest frame 2. Figure 2 As shown, the arm swing member 3 has an arm resting position 30 to accommodate the arm. The arm resting position 30 is located above the armrest frame 2. A power source 34 is installed inside the armrest frame 2. Driven by the power source 34, the arm swing member 3 moves the arm up and down, thus stretching the arm and improving the massage function of the massage chair. Since the arm swing member 3 is rotatably mounted on the armrest frame 2, it swings outside the armrest frame 2. There is no need to provide space between the arm swing member 3 and the armrest frame 2 for it to swing, which can hide the power source and transmission structure, significantly improving the safety and aesthetics of the product.

[0016] like Figure 3As shown, the arm swing member 3 is rotatably mounted on the armrest frame 2 via a rotating shaft 31. A power source 34 is connected to the rotating shaft 31 via a transmission assembly located inside the armrest frame 2. The power source 34 drives the rotating shaft 31 to rotate via the transmission assembly, thereby causing the arm swing member 3 to swing. Both the transmission assembly and the power source 34 are installed inside the armrest frame 2. Since the armrest frame 2 has two side decorative panels, they can provide a concealing effect, making the massage chair more aesthetically pleasing and safer.

[0017] Example 1: As Figure 3 As shown, the power source 34 is an actuator (including a cylinder and an electric push rod). The actuator's mounting point is hinged to the handrail frame 2. The transmission assembly includes a transmission rod 33 and a connecting arm 32. One end of the connecting arm 32 is connected to the rotating shaft 31, and the other end of the connecting arm 32 is hinged to one end of the transmission rod 33. The other end of the transmission rod 33 is connected to the actuator's telescopic rod. The actuator's telescopic rod drives the rotating shaft 31 to rotate through the transmission rod 33 and the connecting arm 32, thereby causing the arm swing member 3 to swing.

[0018] Example 2: As Figure 3 As shown, the power source 34 is an actuator (including a cylinder and an electric push rod). The actuator's mounting point is hinged to the handrail frame 2. The transmission assembly includes a connecting arm 32. One end of the connecting arm 32 is connected to the rotating shaft 31, and the other end of the connecting arm 32 is hinged to the actuator's telescopic rod. The actuator's telescopic rod drives the rotating shaft 31 to rotate through the connecting arm 32, thereby causing the arm swing member 3 to swing.

[0019] Example 3: The power source is an electric motor. In this case, the transmission assembly includes a first synchronous pulley, a second synchronous pulley, and a synchronous belt. The first synchronous pulley is connected to the rotating shaft 31, the second synchronous pulley is connected to the output shaft of the motor, and the synchronous belt is wound around the first and second synchronous pulleys. The motor drives the synchronous belt to rotate the rotating shaft 31, thereby causing the arm swing member 3 to swing.

[0020] To prevent fingers from being pinched, such as Figure 1 As shown, an anti-pinch signal source is provided on the upper surface 20 of the handrail frame 2 relative to the arm swing member 3. This anti-pinch signal source is electrically connected to the controller, which controls the power source 34 to work. When the anti-pinch signal source detects any object approaching the upper surface 20 of the handrail frame 2, the controller controls the power source 34 to stop outputting power, so that the arm swing member 3 will no longer swing down, preventing the object from being trapped between the arm swing member 3 and the upper surface 20 of the handrail frame 2.

[0021] The anti-pinch signal source here can be an infrared sensor, a contact sensor, a light sensor, or a capacitive touch sensor. Any sensor that can sense objects is acceptable.

[0022] Finally, it is worth mentioning that the arm resting position 30 of the arm swing member 3 has an arm massage mechanism. The arm massage mechanism includes a massage head that can press and massage the arm. In this way, the arm swing member 3 can not only swing and stretch the arm up and down, but also press and massage the arm, significantly improving the massage effect.
