Description

Technical Field

[0001] This utility model relates to the field of massagers, specifically to a wire winding mechanism and a massager. Background Technology

[0002] The English word for massager is "massager." It is a new generation of health care equipment developed based on physics, bionics, bioelectricity, traditional Chinese medicine, and years of clinical practice. It not only boasts eight simulated functions, allowing users to experience the wonderful sensations of acupuncture, tuina, massage, percussion, cupping, scraping, slimming, and immune regulation, but also has unique effects in treating hypertension. Using several independent soft-touch massage heads, it can relax muscles, soothe nerves, promote blood circulation, enhance cell metabolism, and improve skin elasticity. It can relieve fatigue, significantly reduce various chronic and acute pains and muscle soreness, relax the body, reduce stress, and decrease wrinkles.

[0003] In the process of developing this utility model, the inventors discovered the following problems in the prior art: Some mechanisms in a massager need to move linearly to perform massage at different positions or with different movements. Therefore, during the movement of the massage mechanism, the corresponding power cord needs to move as well. Existing designs use a power cord with a design margin for adaptation. However, after multiple movements, the connection point of the power cord is prone to loosening or separation, causing the massage mechanism to lose power and malfunction. Furthermore, the design of a power cord with a design margin can easily lead to interference with other structures in the massage device, resulting in unnecessary malfunctions. Utility Model Content

[0004] The purpose of this invention is to provide a cord retraction mechanism and a massager, which aims to improve the problem that the power cord of the existing massage mechanism does not have a retraction function, causing the connection of the power cord to be prone to failure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cable winding mechanism, comprising a walking component that moves back and forth on a frame, wherein the frame is provided with a cavity structure for storing the power cable of the walking component; It also includes a sliding member that slides within the cavity structure and an elastic member that drives the sliding member to reset. The middle part of the power cord is located on the sliding member and is housed within the cavity structure along with the sliding member. When the traveling component moves away from the cavity structure, it pulls the power cable out of the cavity structure.

[0006] As a preferred structure of this utility model, the sliding member is provided with a first roller for the power line to slide.

[0007] In a preferred embodiment of this invention, the elastic element is a spring or an elastic band.

[0008] As a preferred structure of this utility model, the sliding member includes a bottom plate and a top plate that are detachably mounted on the axle of the first roller, and the bottom plate and / or the top plate are provided with a mounting part that is connected to the elastic member.

[0009] As a preferred structure of this utility model, a second roller is provided at the opening of the cavity structure, which is connected to one end of the power line of the walking component to provide sliding friction at the top and bottom.

[0010] As a preferred structure of this utility model, the other end of the power cord is provided with a fixing member that is provided at the opening of the cavity structure to fix the power cord.

[0011] As a preferred structure of this utility model, the fixing member is a pressing structure of pressing plate and screw locking or an adhesive structure of glue bonding.

[0012] As a preferred structure of this utility model, it also includes a circuit board electrically connected to the other end of the power cord, and the frame is provided with a mounting cavity for accommodating the circuit board.

[0013] This utility model also provides a massager, including the winding mechanism described above.

[0014] By adopting the above technical solution, this utility model has the following advantages compared with the prior art: 1. When the massage mechanism moves away from the cavity structure along the sliding track, its power cord is simultaneously pulled out of the cavity structure. Driven by the power cord, the sliding component overcomes the elastic force of the elastic element and moves within the cavity structure. When the external force stops or the massage mechanism returns to its original position, the elastic element releases its stored potential energy, pushing the sliding component back along the cavity structure. This causes the power cord to retract or be stored back into the cavity structure, thus achieving automatic power cord retraction. This prevents the cord from becoming tangled or twisted, effectively protecting the power cord, extending its service life, reducing the risk of malfunctions due to loose or interfered wiring, and improving the stability and safety of the massager's operation.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] Additionally, it should be noted that the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" are all based on the orientation or positional relationship shown in the accompanying drawings. They are merely for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element of this utility model must have a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] When an element is referred to as being "fixed to," "set on," or "contained on" another element, it can be directly on or indirectly on that other element. When an element is referred to as being "connected to," it can be directly connected to or indirectly connected to that other element.

[0020] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Example 1 Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment provides a cable retraction mechanism, including a walking member 2 that moves back and forth on a frame 1, and a cavity structure 10 provided on the frame 1 for storing the power cord 3 of the walking member 2; it also includes a sliding member 20 that slides within the cavity structure 10 and an elastic member 21 that drives the sliding member 20 to reset, the middle part of the power cord 3 is located on the sliding member 20 and is stored in the cavity structure 10 along with the sliding member 20; when the walking member 2 moves away from the cavity structure 10, it drives the power cord 3 to be pulled out from the cavity structure 10.

[0022] The cable retraction mechanism disclosed herein can be applied to equipment or connector structures that require the power cord 3 to be pulled out for use. After the power cord is pulled out for use, the elastic member 21 can drive the sliding member 20 to reset, so that the power cord 3 moves with the sliding member 20 and is stored in the cavity structure 10 of the frame 1, thus completing the purpose of storing the power cord 3.

[0023] Specifically, a sliding track (such as a raised or recessed track, a rack and pinion track, or the aforementioned track or track working in conjunction with rollers on the traveling component 2) is provided on the frame 1, allowing the traveling component 2 to move along the sliding track. The traveling component 2 can be a massage mechanism or other electrical components, such as moving parts in a power strip, lamp, or household appliance, with its power cord 3 automatically retracted via this cord retraction mechanism. The following explanation uses a massage mechanism as an example.

[0024] In use, as the massage mechanism moves away from the cavity structure 10 along the sliding track, its power cord 3 is simultaneously pulled out of the cavity structure 10. Driven by the power cord 3, the sliding member 20 overcomes the elastic force of the elastic member 21 and moves within the cavity structure 10. When the external force stops or the massage mechanism returns to its original position, the elastic member 21 releases its stored potential energy, pushing the sliding member 20 back to its original position along the cavity structure 10. This causes the power cord 3 to retract or be stored back into the cavity structure 10, thus achieving automatic power cord retraction and preventing tangled or messy wiring. This process requires no human intervention, improving the convenience and safety of the device.

[0025] The elastic element 21 disclosed herein can be made of spring, sheet, elastic band, or rubber material, etc. The elastic force needs to be reasonably designed according to the length, weight, and frictional resistance of the power cord 3 to ensure that the sliding element 20 resets smoothly without jamming. As a preferred option, the spring is installed inside the cavity structure 10 and connected to the sliding element 20 to provide the elastic force for the power cord 3 to reset when pulled out.

[0026] Furthermore, such as Figure 2 and Figure 4As shown, the sliding member 20 of this disclosure is provided with a first roller 201 for the power cord 3 to slide on. The first roller 201 can be understood as a pulley structure, so that when the power cord 3 is pulled and moved, it can slide smoothly through the first roller 201, reducing frictional resistance and preventing damage to the power cord 3 due to repeated bending. At the same time, the outer peripheral surface of the first roller 201 can be designed as an arc-shaped groove structure to fit the diameter of the power cord 3 and prevent it from derailing or shifting during movement. In addition, it can also reduce wear on the power cord 3 during repeated pulling and retraction, and extend its service life.

[0027] Specifically, such as Figure 5 As shown, the sliding member 20 of this disclosure includes a base plate 202 and a top plate 203 detachably mounted on the axle of the first roller 201, and the base plate 202 and / or the top plate 203 are provided with a mounting part 204 connected to the elastic member 21. The mounting part 204 can be a slot or a connecting hole for fixing the end of the elastic member 21, or a column structure provided between the base plate 202 and the top plate 203 for stably fixing the elastic member 21.

[0028] The detachable connection between the base plate 202 and the top plate 203 facilitates the installation and replacement of the first roller 201, while ensuring that the power cord 3 remains between the base plate 202 and the top plate 203 when the sliding member 20 moves within the cavity structure 10. If the mounting part 204 adopts a columnar structure, it can form a dual-point limiting effect on the power cord 3 with the first roller 201, ensuring that the power cord 3 always follows or drives the movement within the sliding member 20, thus guaranteeing the stability of the movement.

[0029] like Figure 3 and Figure 4 As shown, the cavity structure 10 of this disclosure has a second roller 101 at its opening, which provides sliding friction to the power cord 3 connected to one end of the traveling member 2. The second roller 101 has a cylindrical central shaft, and a freely rotating roller is installed outside the central shaft. The outer circumference of the roller has anti-slip textures to guide the power cord 3 smoothly in and out of the cavity structure 10, reduce its direct friction with the edge of the opening, reduce wear on the power cord 3 during repeated pulling and retraction, and extend its service life. The position of the second roller 101 forms a spatial linkage with the first roller 201, so that the power cord 3 maintains reasonable tension during pulling or retraction, avoiding deviation or jamming.

[0030] The other end of the power cord 3 disclosed herein is provided with a fixing member (not shown) at the opening of the cavity structure 10 for securing the power cord 3. The fixing member can be a clamping plate and a screw, clamping and fixing the other end of the power cord 3 to the opening of the cavity structure 10, preventing the connector at the other end of the power cord 3 from being pulled, thus effectively avoiding loosening or damage to the connector due to external force. Alternatively, an adhesive structure can be used for fixing, achieving the purpose of securing the other end of the power cord 3. The fixing end of the power cord 3 to the traveling member 2 can also be fixed using the above structure, strengthening the fixing effect of the power cord 3 and ensuring a stable and reliable connection during frequent extension and retraction.

[0031] like Figure 3 and Figure 4 As shown, this disclosure also includes a circuit board 30 electrically connected to the other end of the power cord 3. The frame 1 has a mounting cavity 31 for accommodating the circuit board 30. The design of the circuit board 30 facilitates the installation of other electrical components, such as connectors for the power cord 3, sensors, chips, or power supplies, and allows for the configuration of electrical components as needed. This facilitates the installation and connection of the power cord 3, while also improving the integration and maintenance convenience of the overall electrical system.

[0032] Example 2 This embodiment provides a massager, including a cord retraction mechanism as described in Embodiment 1. The massage mechanism within the massager is the traveling component in this embodiment, allowing it to reciprocate along guide rails within the frame, providing a simulated manual massage to the user's back, waist, and other areas. The power cord of the massage mechanism is retracted or extended within the cavity structure via the cord retraction mechanism. That is, as the massage mechanism moves, the power cord is simultaneously retracted and extended, maintaining appropriate tension to prevent tangling or excessive stretching. The cord retraction mechanism, through the coordinated action of two rollers, ensures smooth sliding of the power cord during dynamic operation, reducing the risk of wear. This achieves the goal of stably retracting or extending the power cord in conjunction with the massage mechanism, improving the overall smoothness and safety of the massager's operation.

[0033] The above description is merely a preferred 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.
