Description

Technical Field

[0001] This utility model relates to the field of massagers, and in particular to a composite motion structure for a massager. Background Technology

[0002] Massagers, as a common everyday item, are highly favored for their ability to relieve muscle tension and promote blood circulation, and market demand is steadily increasing accordingly.

[0003] Current massagers primarily rely on vibration or oscillation to provide physical massage to the body. To facilitate daily use and storage, massagers are generally designed to be lightweight and compact, but this often results in less effective massage. For example, when using vibration, the vibration transmitted by a single motor covers a limited area, meaning a single motor can only massage a single point on the body. Due to the limitations of lightweight design and miniaturization, the number of motors cannot be increased. When using oscillation, the massager uses an eccentric rotating mechanism to generate rotation or extension, but again, the eccentric rotation radius is too small, limiting the massage range. Therefore, the lightweight and miniaturized design of massagers, whether using vibration or oscillation, limits the massage range and hinders the achievement of optimal massage results. Utility Model Content

[0004] The purpose of this invention is to provide a massager with a composite motion structure that enables a lightweight and compact design while providing a larger massage range to enhance the massage effect.

[0005] The technical solution provided by this utility model is as follows: a massager with a composite motion structure, including a base, a slide and a drive assembly on the base, the slide slidingly engaging with the base, the slide being connected to the power output end of the drive assembly, the base also having a cylindrical spur gear, the spur gear rotatingly engaging with the base, the spur gear being connected to the power output end of the drive assembly, the slide being sleeved on the spur gear, the slide slidingly engaging with the spur gear along the axial direction of the spur gear, the slide rotatingly engaging with the spur gear along the circumference of the spur gear, the slide having a rotatable gear assembly and a vertically arranged swing rod on the slide, the first end of the swing rod being fixedly connected to the gear assembly, the first end of the swing rod rotatingly engaging with the slide, the second end of the swing rod being bent, the gear assembly meshing with the spur gear, the gear assembly sliding relative to the spur gear along the axial direction of the spur gear.

[0006] In the aforementioned massager composite motion structure, the gear assembly includes a first bevel gear, a second bevel gear, and a first transmission gear. The first transmission gear is coaxially connected to the second bevel gear. The swing rod is fixedly connected to the first bevel gear. The first bevel gear meshes with the second bevel gear. The second bevel gear meshes with the first transmission gear. The first transmission gear meshes with the spur gear. The first transmission gear slides relative to the spur gear along the axial direction of the spur gear.

[0007] In the above-described composite motion structure of the massager, the side of the first transmission gear adjacent to the spur gear extends through the side of the slide.

[0008] In the above-mentioned massager composite motion structure, the slide is provided with two spaced-apart first connecting rings, the spur gear passes through the two first connecting rings, the spur gear rotates with the two first connecting rings, the two first connecting rings slide with the spur gear along their axial direction, and the first transmission gear is located between the two first connecting rings.

[0009] In the above-mentioned massager composite motion structure, the drive component includes a motor module and a drive gear fixedly connected to the power output end of the motor module, and the drive gear meshes with the spur gear.

[0010] In the above-mentioned massager composite motion structure, a rotatable lead screw passes through the slide, the lead screw is rotatably engaged with the base, a second transmission gear is coaxially provided on one end of the lead screw and meshes with the drive gear, and a guide block is provided on the slide that is locked in the threaded groove of the lead screw, the guide block slides along the threaded groove of the lead screw and engages with the lead screw.

[0011] In the aforementioned composite motion structure of the massager, the threaded groove of the lead screw includes a bent rising section and a falling section, which are symmetrically arranged about the axis of the lead screw and are connected end to end to form a closed loop structure.

[0014] A buffer block is provided on the end of the swing rod away from the slide block.

[0015] The beneficial effects of this utility model after adopting the above technical solution are as follows:

[0016] This technical solution uses a drive component to drive a slide on the base, causing the slide to move the swing arm and other components back and forth on the base. This allows the swing arm to achieve a certain massage range along the length of the base. During sliding, the slide slides along the axis of a spur gear, which rotates synchronously under the drive component. The gear assembly on the slide meshes with the spur gear, and the first end of the swing arm is connected to the gear assembly, causing it to rotate synchronously with the gear assembly. Because one end of the swing arm is bent, the two ends are on different axes. As the first end of the swing arm rotates, the second end simultaneously rotates eccentrically, allowing the swing arm to also achieve a certain massage range along the width of the base. The massage range of the swing arm is superimposed in both the length and width directions of the base, thus expanding the massage range multiplicatively. This results in a lightweight and compact massager with a large massage range, enhancing the massage effect. Attached Figure Description

[0023] The technical solution of this utility model will be further described in detail below with reference to specific embodiments, but this does not constitute any limitation on this utility model.

[0024] Example 1:

[0025] like Figure 1-4 As shown, the massager's composite motion structure includes a base 1, a slide 3 and a drive assembly on the base 1. The slide 3 is slidably engaged with the base 1 and connected to the power output end of the drive assembly. The base 1 also has a cylindrical spur gear 2, which is rotatably engaged with the base 1 and connected to the power output end of the drive assembly. The slide 3 is fitted onto the spur gear 2, and the slide 3 is slidably engaged with the spur gear 2 along its axial direction and rotatably engaged with the spur gear 2 along its circumference. The slide 3 has a rotatable gear assembly and a vertically mounted swing rod 4. The first end of the swing rod 4 is fixedly connected to the gear assembly and rotatably engaged with the slide 3. The second end of the swing rod 4 is bent. The gear assembly meshes with the spur gear 2 and slides relative to the spur gear 2 along its axial direction.

[0026] The specific working principle is as follows: the slide block 3 on the base 1 is driven by the drive component, causing the slide block 3 to drive the swing rod 4 and other components to slide back and forth on the base 1. This allows the swing rod 4 to obtain a certain massage range along the length of the base 1. When the slide block 3 slides, it slides along the axis of the spur gear 2. The spur gear 2 rotates synchronously under the drive component. The gear assembly on the slide block 3 meshes with the spur gear 2. One end of the swing rod 4 is connected to the gear assembly, so the swing rod 4 rotates synchronously with the rotation of the gear assembly. Because one end of the swing rod 4 is bent, the two ends of the swing rod 4 are on different axes. When the first end of the swing rod 4 rotates, the second end of the swing rod 4 rotates eccentrically, allowing the swing rod 4 to also obtain a certain massage range along the width of the base 1. The massage range of the swing rod 4 is superimposed in both the length and width directions of the base 1, so that the massage range of the swing rod 4 is expanded in a product manner. This allows the lightweight and compact massager to have a large massage range, thereby enhancing the massage effect.

[0027] like Figure 3 As shown, the specific structure of the gear assembly is as follows: the gear assembly includes a first bevel gear 8, a second bevel gear 7, and a first transmission gear 5. The first transmission gear 5 and the second bevel gear 7 are coaxially connected. The swing rod 4 is fixedly connected to the first bevel gear 8. The first bevel gear 8 and the second bevel gear 7 are meshed together. The second bevel gear 7 is meshed with the first transmission gear 5. The first transmission gear 5 is meshed with the spur gear 2. The first transmission gear 5 slides relative to the spur gear 2 along the axial direction of the spur gear 2.

[0028] In actual operation, the slide block 3 slides along the axial direction of the spur gear 2 on the rotating spur gear 2. While the slide block 3 slides, it drives the first transmission gear 5 to slide relative to the spur gear 2, so that the first transmission gear 5 can also mesh with the spur gear 2 even when sliding relative to the spur gear 2. This ensures that the first transmission gear 5 and the spur gear 2 are always in a meshing state. The first transmission gear 5 then drives the swing rod 4 on the slide block 3 to rotate by meshing with the second bevel gear 7 and the first bevel gear 8 in sequence.

[0029] like Figure 2 As shown, in a specific implementation, the side of the first transmission gear 5 adjacent to the spur gear 2 passes through the side of the slide block 3.

[0030] Combination Figure 2 and Figure 3 As shown, the specific connection method between the slide block 3 and the spur gear 2 is as follows: the slide block 3 is provided with two spaced first connecting rings 31, the spur gear 2 passes through the two first connecting rings 31, the spur gear 2 and the two first connecting rings 31 are rotatably engaged, the two first connecting rings 31 are slidably engaged with the spur gear 2 along their axial direction, and the first transmission gear 5 is located between the two first connecting rings 31.

[0031] like Figure 3 As shown, the specific structure of the drive assembly is as follows: the drive assembly includes a motor module and a drive gear fixedly connected to the power output end of the motor module. The drive gear meshes with the spur gear 2.

[0032] The motor module includes a motor and a reducer connected to the power output end of the motor. The drive gear is connected to the power output end of the reducer. In addition, the drive component can also be a rotary cylinder. This embodiment does not impose too many restrictions on this.

[0033] Combination Figure 1 and Figure 4 As shown, in this embodiment, a rotatable lead screw 6 passes through the slide block 3. The lead screw 6 is rotatably engaged with the base 1. A second transmission gear 62 is coaxially provided on one end of the lead screw 6 and meshes with the drive gear. A guide block 33 is provided on the slide block 3 and is locked in the threaded groove of the lead screw 6. The guide block 33 slides along the threaded groove of the lead screw 6 and engages with the lead screw 6.

[0034] In some embodiments, in addition to using the lead screw 6 to drive the slide block 3 to reciprocate, a crank-slider mechanism and a cam mechanism or other transmission mechanisms can also be used to drive the slide block 3 to reciprocate. This embodiment does not impose too many restrictions on this.

[0035] like Figure 4As shown, preferably, the threaded groove of the lead screw 6 includes a bent rising section 63 and a falling section 64, which are symmetrically arranged about the axis of the lead screw 6 and are connected end to end to form a closed loop structure.

[0036] In practical implementation, the threaded groove of the lead screw 6 can be a standard threaded groove, where the threaded grooves extend spirally and terminate at both ends of the lead screw 6. The lead screw 6, in cooperation with the forward and reverse motor, causes the guide block 33 to move back and forth along the threaded groove of the lead screw 6. Alternatively, the threaded groove of the lead screw 6 can be a non-standard threaded groove, and the structure of the non-standard threaded groove can take various forms. For example, the two ends of the rising section 63 extend spirally to the opposite sides of the axis of the lead screw 6, and the two ends of the descending section 64 also extend spirally to the opposite sides of the axis of the lead screw 6. When the rising section 63 and the descending section 64 are connected end to end, their middle parts intersect and connect, and the closed loop structure formed by the rising section 63 and the descending section 64 is in the shape of an "8". Or, the two ends of the rising section 63 are located on the same side of the axis of the lead screw 6, and the two ends of the descending section 64 are also located on the same side of the axis of the lead screw 6. On the same side of the axis of rod 6, when the rising section 63 and the falling section 64 are connected end to end, the closed loop structure formed by the rising section 63 and the falling section 64 is elliptical; or the two ends of the rising section 63 extend in an S-shape to the two opposite sides of the axis of the screw 6, and the two ends of the falling section 64 also extend in an S-shape to the two opposite sides of the axis of the screw 6. When the rising section 63 and the falling section 64 are connected end to end, the closed loop structure formed by the rising section 63 and the falling section 64 is gourd-shaped on the radial projection plane of the screw 6. In addition to the above-mentioned non-standard thread groove, other non-standard thread grooves can also be used. This embodiment does not impose too many restrictions on this. If a non-standard thread groove is used for the screw 6, when it cooperates with a unidirectional rotating ordinary motor, the thread groove guide block 33 can also move back and forth between the two ends of the screw 6, reducing the cost of motor procurement, debugging and later maintenance.

[0037] Another preferred embodiment uses a lead screw 6 with a figure-eight shape formed by the rising section 63 and the falling section 64 in a closed loop structure.

[0038] Combination Figure 1 , Figure 3 and Figure 4 As shown, in another preferred embodiment, a guide portion 61 is coaxially provided on the opposite end of the lead screw 6, and the slide block 3 slides in cooperation with the guide portion 61 along the axial direction of the lead screw 6.

[0039] The guide section 61 improves the stability and sliding accuracy of the slide block 3 sliding on the lead screw 6.

[0040] Combination Figure 1 and Figure 3As shown, the specific connection between the slide block 3 and the lead screw 6 is as follows: the slide block 3 is provided with two spaced second connecting rings 32, the lead screw 6 passes through the two second connecting rings 32, the lead screw 6 and the two second connecting rings 32 are rotatably engaged, the two second connecting rings 32 are slidably engaged with the lead screw 6 along their axial direction, and the guide block 33 is provided on the inner side of one of the second connecting rings 32.

[0041] Combination Figure 1 , Figure 2 and Figure 3 As shown, in addition, a buffer block 41 is provided on the end of the swing rod 4 away from the slide block 3. The buffer block 41 is sleeved on the end of the swing rod 4 for direct contact with the body. The buffer block 41 can be a soft plastic block, or it can be elastic silicone or rubber. This embodiment does not impose too many restrictions on this.

[0042] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
