Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a foot massager for ankle stretching. Background Technology

[0002] With the development of foot massage technology, various foot massagers have been widely used in home healthcare, medical rehabilitation, and daily physiotherapy. Foot massage devices typically stimulate and relax acupoints on the soles of the feet through methods such as airbag compression, roller kneading, and heating steam, thus meeting users' basic massage needs to a certain extent. However, most existing foot massage devices focus on the sole massage function and generally do not involve active stretching and mobility design for the ankle joint. As an important hub connecting the lower leg and foot, the ankle's flexibility and blood circulation directly affect lower limb health. Long-term lack of effective activity can lead to stiffness, swelling, and even sports injuries.

[0003] Prior art, such as Chinese patent application "A Multifunctional Foot Massager," application number 202010123456.7, discloses a foot massage device combining airbag compression and roller kneading, which achieves massage of the soles and insteps through the cooperation of multiple sets of airbags and rollers. The aforementioned patent application provides a comprehensive foot massage solution that can simultaneously act on the soles and insteps, improving the coverage and comfort of the massage. However, this device is not specifically designed for ankle joint flexibility training, making it difficult to meet users' needs for ankle stretching.

[0004] Therefore, developing a foot massage device with ankle stretching function has important practical value. Utility Model Content

[0005] This utility model provides a new design for a foot massager, which achieves active ankle stretching by introducing a swing drive component. This retains the advantages of traditional foot massage while making up for the shortcomings of existing technologies in ankle mobility.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A foot massager for ankle stretching includes a support frame, a foot support platform, and a swing drive assembly. The foot support platform is pivotally connected to the support frame via a first pivot shaft extending laterally. The swing drive assembly is mounted on the support frame and includes a drive unit, a slider, and a connecting rod. The slider is located on the left and / or right side of the foot support platform. Each slider corresponds to a connecting rod. One end of the connecting rod is pivotally connected to the slider, and the other end is pivotally connected to the foot support platform via a second pivot shaft. The drive unit drives the slider to slide back and forth along the support frame and drives the foot support platform to swing back and forth relative to the support frame via the connecting rod.

[0007] As a preferred technical solution, the first pivot shaft is located above or below the slider's movement trajectory.

[0008] As a preferred technical solution, the drive unit is one of a pneumatic cylinder, a hydraulic cylinder, or a servo motor; When the drive unit is a servo motor, the servo motor is threadedly connected to the slider via a screw.

[0009] As a preferred technical solution, the swing angle range of the foot support platform is -35° to 35°.

[0010] As a preferred technical solution, the top or bottom of the slider is provided with a connecting foot that is pivotally connected to the connecting rod, and the top or bottom of the slide rail is provided with a through groove to accommodate the connecting foot.

[0011] As a preferred technical solution, the first pivot shaft is an integral shaft that runs through the left and right sides of the foot support platform or two independent shafts that are coaxially arranged.

[0012] As a preferred technical solution, the second pivot shaft is located on the front or rear side of the first pivot shaft.

[0013] As a preferred technical solution, the plane where the slider and the slide rail fit together is provided with a groove extending along the direction of the movement trajectory, and a ball is embedded in the groove. The ball contacts the slide rail and rolls.

[0014] As a preferred technical solution, the supporting frame is provided with slide rails on both the left and right sides of the foot support platform, and each slide rail is provided with a slider.

[0015] The working principle of this invention is as follows: When the drive unit is activated, the slider slides back and forth along the slide rail. The movement of the slider is transmitted to the foot support platform through the connecting rod, causing it to swing around the first pivot axis. The swinging of the foot support platform causes the user's foot to move accordingly, thereby achieving active stretching of the ankle joint. When the drive unit stops working, the slider returns to its initial position, and the foot support platform also returns to its initial state. Throughout the process, the movement trajectory of the slider overlaps with the longitudinal projection of the first pivot axis, ensuring that the swing amplitude of the foot support platform is uniform and stable.

[0016] The beneficial effects of this utility model are: This invention provides a foot massager for ankle stretching. By introducing a swing drive component, it solves the problem of existing foot massagers lacking ankle stretching function. It features an independent drive module and a linked swing arm mechanism to achieve automatic up-and-down reciprocating swinging of the foot, simulating professional techniques for ankle flexion and extension training. This effectively improves local blood circulation, prevents joint stiffness, and enhances the overall massage and rehabilitation effect, meeting the modern family health care demand for multifunctional and intelligent foot massage equipment.

Detailed Implementation

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Example: This example describes a foot massager for ankle stretching, such as... Figure 1-6As shown, the device includes a support frame 1, a foot support platform 2, and a swing drive assembly 3. The foot support platform 2 is connected to the support frame 1 via a first pivot shaft 21. The swing drive assembly 3 is mounted on the support frame 1 and consists of a drive unit 31, a slider 32, and a connecting rod 33. The active stretching function of the ankle joint is achieved through specific connections and positional arrangements between the components.

[0022] The foot support platform 2 serves as a support component for the user's feet. Its surface is equipped with foot massage units 23, distributed in the top area of ​​the foot support platform 2, used to stimulate acupoints on the soles of the feet, further enhancing user comfort. The foot massage units 23 can take the form of raised massage points or vibration devices, fixed to the surface of the foot support platform 2 and connected to an external power source. The two sides of the foot support platform 2 are connected to the support frame 1 via first pivot shafts 21. The first pivot shafts 21 extend through the left and right sides of the foot support platform 2 or can be designed as two independent shafts. The position of the first pivot shaft 21 determines the swing axis of the foot support platform 2, and its longitudinal projection partially overlaps with the movement trajectory of the slider 32, ensuring that the movement of the slider 32 can be effectively converted into the reciprocating swing of the foot support platform 2. The installation height of the first pivot shaft 21 is located above or below the movement trajectory of the slider 32, forming a stable lever-type transmission structure.

[0023] The core of the swing drive assembly 3 lies in the cooperation between the slider 32 and the connecting rod 33. The slider 32 is located on the left and / or right side of the foot support platform 2, and corresponds one-to-one with the connecting rod 33. It should be noted that the slide rail 11 restricts the slider 32 on its upper, lower, left, and right sides, so that the slider 32 can only move in the front-back direction. Each slider 32 has a connecting foot 321 at its top or bottom, and the connecting foot 321 passes through the through groove 111 at the top or bottom of the slide rail 11 and connects to one end of the connecting rod 33. The other end of the connecting rod 33 is connected to the foot support platform 2 through the second pivot shaft 22, forming a spatially misaligned connection. The second pivot shaft 22 is located in front of or behind the first pivot shaft 21. This arrangement simplifies the assembly process of the connecting rod 33 and the foot support platform 2, and improves the compactness of the overall structure. The connection between the connecting rod 33 and the slider 32 and the foot support platform 2 adopts a detachable design, which facilitates later maintenance and replacement.

[0024] The drive unit 31 provides the power source for the movement of the slider 32, and its specific form can be a pneumatic cylinder, a hydraulic cylinder, or a servo motor. When the drive unit 31 is a pneumatic cylinder or a hydraulic cylinder, the slider 32 is directly connected to its piston rod; when the drive unit 31 is a servo motor, the servo motor is threadedly connected to the slider 32 via a screw. The rotational motion of the screw is converted into the linear motion of the slider 32, and the slider 32 slides back and forth along the slide rail 11 on the support frame 1. The motion trajectory of the slider 32 overlaps with the longitudinal projection of the first pivot shaft 21 to ensure that the motion of the slider 32 can be uniformly transmitted to the foot support platform 2.

[0025] The frictional resistance between the slider 32 and the slide rail 11 is reduced by a ball bearing structure. The plane where the slider 32 and the slide rail 11 mate is provided with a groove 322 extending along the movement trajectory of the slider 32. Ball bearings are embedded in the groove 322, and these balls contact and roll with the slide rail 11. This ball bearing structure not only improves the smoothness of the slider 32's movement but also extends the service life of both the slider 32 and the slide rail 11. A through slot 111 at the top or bottom of the slide rail 11 accommodates the connecting feet 321 of the slider 32, preventing interference between the slider 32 and the slide rail 11 during movement.

[0026] The swing angle range of the foot support platform 2 is -35° to 35°. The magnitude of the swing angle is determined by the stroke of the slider 32, which is controlled by the output parameters of the drive unit 31. For example, when the drive unit 31 is a servo motor, the stroke of the slider 32 can be changed by adjusting the number of rotations of the servo motor, thereby adjusting the swing amplitude of the foot support platform 2. This design allows the present invention to flexibly adjust the ankle tensile strength according to the user's actual needs.

[0027] The support frame 1 serves as the main structure of the entire device, and its shape and size are designed according to the actual usage scenario. The support frame 1 includes a support structure located on both sides of the foot support platform 2. The support structure is provided with a groove to form the slide rail 11, that is, the slide rail 11 is a groove structure integrally formed on the inner wall of the support structure. In this embodiment, the drive unit 31 is fixed inside the support structure.

[0028] The working principle of this utility model is as follows: When the drive unit 31 is activated, the slider 32 slides back and forth along the slide rail 11. The movement of the slider 32 is transmitted to the foot support platform 2 through the connecting rod 33, causing it to swing around the first pivot axis 21. The swinging of the foot support platform 2 causes the user's foot to move accordingly, thereby achieving active stretching of the ankle joint. When the drive unit 31 stops working, the slider 32 returns to its initial position, and the foot support platform 2 also returns to its initial state. Throughout the process, the movement trajectory of the slider 32 overlaps with the longitudinal projection of the first pivot axis 21, ensuring that the swing amplitude of the foot support platform 2 is uniform and stable.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
