Description

Technical Field

[0001] The utility model relates to the field of personal care appliances, in particular to a handheld vibration massager. Background Art

[0002] Throughout the technological evolution of handheld vibrating massagers, despite numerous designs dedicated to enhancing user experience, compactness and balanced weight distribution have been key constraints. Traditional handheld vibrating massagers, such as massage guns, often suffer from an illogical drive mechanism layout, resulting in a bulky overall size. This not only compromises portability but also makes the vibration and noise generated during operation difficult to control, reducing user comfort.

[0003] Analysis reveals that the primary cause is that the drive mechanism of traditional massagers fails to fully utilize limited space, and the layout of the motor and transmission components is not optimized, resulting in uneven weight distribution and a loose structure. Furthermore, the design of the transmission structure affects the compactness and efficiency of the massager, resulting in energy loss when transmitting driving force, further exacerbating vibration and noise issues.

[0004] To address these issues, the structural design of handheld vibration massagers must be re-examined, particularly the layout of the drive mechanism and transmission structure. By optimizing the drive mechanism's layout, the internal space of the massager can be fully utilized, achieving a compact structure and balanced weight distribution. Furthermore, improving the transmission structure, increasing transmission efficiency, and reducing energy loss are key to reducing vibration and noise, and enhancing the user experience.

[0005] Therefore, developing a handheld vibration massager with a compact structure, balanced weight distribution, and high transmission efficiency has become a top priority. This requires not only innovative design concepts but also in-depth analysis and improvement of existing technologies to achieve a comprehensive improvement in massager performance. Utility Model Content

[0006] The technical problem to be solved by the utility model is how to improve the compactness of the structure of a handheld vibration massager.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a handheld vibration massager, comprising a casing, a movable part, and a driving device for driving the movable part to reciprocate laterally; characterized in that the driving device comprises: a base part, having a first mounting side and a second mounting side longitudinally arranged on both sides, which are connected by a through hole; a motor, mounted on the first mounting side of the base part; a first transmission assembly, mounted on the second mounting side of the base part and connected to the movable part; a second transmission assembly, passing through the through hole, and transmission-connecting the motor and the first transmission assembly; wherein the second transmission assembly transmits the rotational force of the motor to the first transmission assembly; wherein the first transmission assembly converts the rotational force into a driving force that drives the movable part to reciprocate laterally.

[0008] Preferably, the first transmission assembly includes: a sliding member connected to the movable member and slidingly engaged with the second mounting side of the base member in the lateral direction; a first connecting rod, a first end of which is connected to the motor via the second transmission assembly so as to be driven thereby to rotate around a set axis; a second connecting rod, a first end of which is pivotally connected to the sliding member, and a second end of which is pivotally connected to the second end of the first connecting rod.

[0009] Preferably, the second transmission assembly includes a gear portion and a shaft connection portion, the gear portion is engaged with the output shaft of the motor, and the shaft connection portion passes through the through hole and connects the gear portion and the first end of the first connecting rod.

[0010] Preferably, the second mounting side of the base member has a sliding groove, and the sliding member is slidably engaged with the sliding groove.

[0011] Preferably, the handheld vibration massager includes a position detection component for detecting the lateral sliding position of the sliding member, and the position detection component includes a detection member installed on the housing and a displacement member installed on the sliding member.

[0012] Preferably, in the Hall sensor assembly of the position detection assembly, the detection member is a Hall sensor, and the displacement member is a magnet.

[0013] Preferably, a cylindrical groove is formed on the sliding member, and the displacement member is embedded in the cylindrical groove.

[0014] Preferably, a vibration-damping column is provided between the base member and the housing.

[0015] Preferably, the housing includes a first housing portion and a second housing portion, which are connected to each other in the longitudinal direction, and the movable member and the driving device are installed between the first housing portion and the second housing portion.

[0016] Preferably, the rotation axis of the first end of the first connecting rod coincides with the rotation axis of the output shaft of the motor.

[0017] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0018] First, due to the loose structure and uneven weight distribution of traditional handheld vibration massagers, they are bulky, difficult to port, and difficult to control vibration and noise during operation. To address these issues, the present invention redesigns the drive mechanism. Specifically, by mounting the motor on the first mounting side of the base member, mounting the first transmission assembly on the second mounting side of the base member, and connecting the motor and the first transmission assembly via the second transmission assembly, this design fully utilizes the space on both sides of the base member, making the overall structure of the massager more compact.

[0019] The compact design offers several positive benefits. First, the compact structure reduces the size of the massager, improving portability and making it easier for users to carry and use. Second, the compact structure also helps reduce vibration and noise during operation. This is because the compact structure allows for tighter connections between components, reducing vibration and noise caused by loose components or excessive gaps.

[0020] Furthermore, the present invention improves transmission efficiency and reduces energy loss by optimizing the transmission structure. Specifically, the first transmission assembly converts the motor's rotational force into a driving force that propels the movable member in a lateral reciprocating motion. This process, through rational connecting rod design and sliding engagement, results in a smoother and more efficient transmission. Furthermore, the inclusion of a position detection assembly enables the massager to detect the position of the sliding member in real time, enabling precise control of massage force and position, further enhancing the user experience.

[0021] In summary, thanks to the compact structural design and optimized transmission structure of this utility model, the handheld vibration massager has significantly improved its size, portability, vibration and noise control, and transmission efficiency. These technical effects work together to improve the overall performance of the massager, making this utility model a qualitative leap in user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. The components of the embodiments of the present invention generally described and illustrated in the accompanying drawings can be arranged and designed in a variety of different configurations. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0031] Combine Figures 1 to 11 In one embodiment, the handheld vibration massager of the present application comprises a housing 1, a movable member 2 and a driving device 3. The driving device 3 is mounted on the housing 1 to drive the movable member 2 to reciprocate along the horizontal direction X. This will be further described below.

[0032] The housing 1 comprises a first housing 1A and a second housing 1B, Figure 7 The two are connected along the longitudinal direction Y, and the movable part 2 and the driving device 3 are installed between the first shell 1A and the second shell 1B. The first shell 1A and the second shell 1B can be injection-molded shells, and the two can be connected by fastening screws.

[0033] The movable member 2 is configured to move relative to the housing 1 in a transverse direction X. In one embodiment, the movable member 2 can serve as the portion of the massager that directly contacts the user's skin or limbs to massage the user's limbs. In another embodiment, a massage structure that contacts the user's skin or limbs can be installed on the movable member 2. The movable member 2 can be designed to have a soft surface to avoid damaging the user's skin or limbs.

[0034] The drive device 3 drives the movable member 2 to reciprocate in a short, linear motion along the horizontal direction X. In this embodiment, the drive device 3 comprises a base member 4, a motor 5, a slider 6, a first connecting rod 7, a second connecting rod 8, a second transmission assembly 9, a motor cover 10, and a power supply 11. The slider 6, first connecting rod 7, and second connecting rod 8 constitute the first transmission assembly. The power supply 11, for example, is a rechargeable lithium battery that provides the electrical energy required for the massager to operate.

[0035] Combine Figure 7 、 Figure 9 and Figure 10 The base member 4 has a first mounting side K1 and a second mounting side K2 arranged on both sides along the longitudinal direction Y, which are connected by a through hole S. The base member 4 can be injection molded. A vibration damping column Q is provided between the base member 4 and the housing 1. Figure 3 and Figure 4 , multiple vibration-damping columns Q are distributed on the outer periphery of the base member 4, which play a role in cushioning and reducing the vibration noise when the massager is working. Figure 4 and Figure 5 The first mounting side K1 of the base member 4 has a motor mounting groove 4A, and the second mounting side K2 has a slide groove 4B.

[0036] The motor 5 is mounted on the first mounting side K1 of the base member 4. Specifically, one side of the motor 5 is disposed in the motor mounting slot 4A, and the other side is provided with a motor cover 10. The motor cover 10 is fixed to the first mounting side K1 of the base member 4 by fastening screws, thereby securing the motor 5. The motor 5 is, for example, a brushless motor.

[0037] The aforementioned first transmission assembly is mounted on the second mounting side K2 of the base member 4 and is connected to the movable member 2. Specifically, the sliding member 6 is connected to the movable member 2, and the sliding member 6 slides in engagement with the slide groove 4B of the second mounting side K2 of the base member 4 in the transverse direction X. The first end 7A of the first connecting rod 7 is connected to the motor 5 via the second transmission assembly 9 so as to be driven thereby to rotate about a set axis. In this embodiment, the rotation axis of the first end 7A of the first connecting rod 7 coincides with the rotation axis of the output shaft of the motor 5, but the structure of the second transmission assembly 9 can also be adjusted so that the two do not coincide. The first end of the second connecting rod 8 is pivotally connected to the sliding member 6 via a pivot member P2, and the second end of the second connecting rod 8 is pivotally connected to the second end 7B of the first connecting rod 7 via a pivot member P1.

[0038] The aforementioned second transmission assembly 9 passes through the through hole S and is in transmission connection with the motor 5 and the first transmission assembly. Specifically, the second transmission assembly 9 includes a gear portion 9A and a shaft connection portion 9B. The gear portion 9A meshes with the output shaft of the motor 5 (a common worm gear meshing structure). The shaft connection portion 9B passes through the through hole S and connects the gear portion 9A to the first end of the first connecting rod 7.

[0039] The second transmission assembly 9 transmits the rotational force of the motor 5 to the first transmission assembly, and the first transmission assembly converts the rotational force into a driving force for driving the movable member 2 to reciprocate along the transverse direction X.

[0040] Combine Figure 3 In this embodiment, the handheld vibration massager further includes a position detection component T for detecting the sliding position of the sliding member 6 in the horizontal direction X, which includes a detection component T1 installed on the housing 1 and a displacement component T2 installed on the sliding member 6. Figure 3 In this embodiment, the slider 6 is provided with a cylindrical groove, within which the displacement member T2 is embedded. The position detection component T is, for example, a Hall effect sensor assembly, wherein the detection member T1 is a Hall effect sensor and the displacement member T2 is a magnet. The position detection component T can also be adapted to other types of position sensors. The addition of the position detection component T enables the massager to detect the position of the slider 6 in real time, thereby achieving precise control of massage force and position, further enhancing the user experience.

[0041] The handheld vibration massager of the present application has a motor 5 mounted on a first mounting side of a base member 4, a first transmission assembly mounted on a second mounting side of the base member 4, and a second transmission assembly 9 connecting the motor 5 and the first transmission assembly. This fully utilizes the space on both sides of the base member 4, resulting in a more even weight distribution on both sides of the base member 4 and a more compact overall structure of the massager. This compact structural design brings many positive benefits. Firstly, the compact structure reduces the size of the massager, thereby improving portability and making it more convenient for users to carry and use. Secondly, the compact structure also helps reduce vibration and noise generated by the massager during operation. This is because the compact structure allows for tighter connections between the various components, reducing vibration and noise caused by loose components or excessive clearances. The first transmission assembly converts the rotational force of the motor into a driving force that drives the movable parts in a lateral reciprocating motion. This process, through the rational design of the connecting rod and the sliding fit, ensures smoother and more efficient transmission.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
