[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0027] Combination Figures 1 to 8 In one embodiment, the lower limb massage device of this application includes a fixing frame 1, a foot rest frame 2, a leg rest frame 3, a first telescopic adjustment mechanism 4, a second telescopic adjustment mechanism 5, a foot massage device P1, and a leg massage device P2. The following will further describe the device with reference to the figures. For ease of explanation, the X direction in the figures is defined as the direction from right to left, the Y direction as the direction from back to front, and the Z direction as the direction from bottom to top.

[0028] The mounting bracket 1 can be pivotally connected to the front side of the seat of the massage chair, combining... Figure 5 The upper side of the fixing frame 1 has two pivot ears 1A spaced apart from each other, which are pivotally connected to the base. The fixing frame 1 is provided with two first sliding grooves M1, and the openings of the two first sliding grooves M1 face inward in the left-right direction.

[0029] The foot rest 2 and the fixing frame 1 slide together in the leg-length direction. A foot massage device P1 is mounted on the foot rest 2. The foot massage device P1 may include, for example, an airbag massage component, foot massage rollers, etc. Figure 5 The foot support 2 is provided with two sets of first sliding members N11 and N12, which are arranged on the outer side of the foot support 2 along the left-right direction. The first sliding member N11 is a roller, and the first sliding member N12 is a strip-shaped slider. The two first sliding grooves M1 and the two sets of first sliding members slide in corresponding directions along the leg length, forming a first sliding structure to guide the foot support 2 to slide relative to the fixed frame 1 in the leg length direction. It should be understood that in another embodiment, the positions of the first sliding grooves M1 and the first sliding members can be interchanged, and only one of the rollers or strip-shaped sliders can be retained. The foot support 2 is provided with two second sliding grooves M2, and the openings of the two second sliding grooves M2 face forward along the front-back direction.

[0030] The leg rest 3 is mounted on the foot rest 2 and can slide relative to the foot rest 2 along the length of the leg. A leg massage device P2 is mounted on the leg rest 3. The leg massage device P2 includes a leg massage drive motor P21 and massage rollers that massage the back of the leg under the influence of the leg massage drive motor P21. The leg massage drive motor P21 drives the massage rollers to rotate via a worm gear transmission assembly, a common technology that will not be described in detail here. Figure 7 The leg rest 3 is provided with two second sliding members N2, which are arranged along the front-to-back direction on the rear side of the leg rest 3. The second sliding members N2 are strip-shaped sliders, but can also be adjusted to rollers. The two second sliding grooves M2 and the two second sliding members N2 are respectively slidably engaged along the leg length direction, forming a second sliding structure to guide the leg rest 3 to slide relative to the foot rest 2 in the leg length direction. It should be understood that in another embodiment, the positions of the second sliding grooves M2 and the second sliding members N2 can be interchanged.

[0031] The first telescopic adjustment mechanism 4 is installed between the fixed frame 1 and the foot rest 2 to drive the foot rest 2 to slide relative to the fixed frame 1. Figure 8 In this embodiment, the first telescopic adjustment mechanism 4 is a first telescopic push rod, whose motor side is pivotally connected to the foot support frame 2, and whose telescopic rod end 4B is pivotally connected to the fixed frame 1.

[0032] The second telescopic adjustment mechanism 5 is installed between the foot rest 2 and the leg rest 3 to drive the leg rest 3 to slide relative to the foot rest 2. Figure 8 In this embodiment, the second telescopic adjustment mechanism 5 is a second telescopic push rod, whose motor side is pivotally connected to the foot rest 2, and whose telescopic rod end is pivotally connected to the leg rest 3. Combined with... Figure 3From a rear-to-front perspective, the motor section 4A of the first telescopic push rod is located below the motor section 5A of the second telescopic push rod, and the leg massage drive motor P21 is located above the motor section 5A of the second telescopic push rod. The leg massage drive motor P21, motor section 5A, and motor section 4A are distributed sequentially from top to bottom in the middle of the lower limb massage device, resulting in a more balanced weight distribution on both sides of the lower limb massage device and a more compact overall structure.

[0033] In the lower limb massage device of this application, the foot rest 2 is slidably engaged with the fixed frame 1, and the leg rest 3 is slidably engaged with the foot rest 2. The leg rest 3 can move downward together with the foot rest 2, and can also move upward independently relative to the foot rest 1. Compared with the prior art CN202122022463.6, the leg rest 3 of this application has a larger range of motion and can better adapt to the usage needs of users with different leg lengths.

[0034] This application also provides a massage chair, including a seat and a lower limb massage device pivotally connected to the front side of the seat; the lower limb massage device is any of the lower limb massage devices described in the preceding claims.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
