[0032] Example embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings; however, these embodiments are not intended to limit the scope of the present disclosure, but rather, the present disclosure can be implemented in various forms. Rather, these embodiments are provided in order to enable those skilled in the art to more thoroughly understand and convey the scope of the present disclosure to others skilled in the art.
[0033] It is to be understood that the terms used herein are merely for the purpose of describing particular example embodiments and are not intended to be limiting. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises," "comprising," "including," and "having," are inclusive and therefore specify the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order in which they are described, unless specifically indicated as such. It is also to be understood that additional or alternative steps can be employed.
[0034] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.
[0035] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.
[0036] Existing massagers have an upper stop point (the furthest point where the two clamps are far apart) and a lower stop point (the closest point where the two clamps are close together), causing the two clamps to repeat a simple mechanical opening and closing motion. This results in a single opening and closing pattern, making it unsuitable for simultaneously massaging areas with significant size differences, such as the neck and lower back, thus limiting its applicability. Furthermore, it cannot adjust the massage intensity according to the pressure applied to the massaged area, leading to inconsistent pressure distribution across different sized areas.
[0037] Based on the above considerations, this utility model proposes a massager 100, such as... Figure 1 As shown, the massager 100 includes a housing 110, two clamps 10 rotatably mounted on the housing 110, a drive motor 20, a transmission assembly 30, an angle detection component (not shown), and a control device 40. The drive motor 20 drives the two clamps 10 to move in opposite directions, meaning they move in opposite directions, including moving closer to each other or further apart; that is, the two clamps 10 open and close to adapt to different massage areas and needs. The angle detection component can detect the rotation angle of the clamps 10 relative to the housing 110 in real time, and the control device 40 precisely controls the operation of the drive motor 20 based on the rotation angle information, thereby achieving precise adjustment of the opening and closing stroke of the clamps 10.
[0038] Specifically, the shell 110 is designed to be ergonomic in shape, facilitating the user to hold and operate, and the shell 110 provides support and operation basis for the entire massage instrument 100. The two clamping heads 10 are rotatably arranged on the shell 110 and can perform opening and closing movements. The shape and size of the clamping head 10 can be designed according to different massage parts. For example, different clamping heads 10 can be designed for the neck, shoulders, arms, etc. The clamping head 10 adopts a hard skeleton, and the surface of the clamping head 10 can be covered with soft materials such as silicone or sponge to provide a comfortable massage experience and avoid damage to the skin.
[0039] In some embodiments, the driving motor 20 adopts a servo motor, which is the power source of the massage instrument 100. The driving motor 20 is in driving connection with the two clamping heads 10 through the transmission assembly 30. The driving motor 20 can provide precise torque and speed control to realize smooth opening and closing movements of the two clamping heads 10. The performance parameters of the driving motor 20, such as power, speed range, and torque, should be selected according to the design requirements of the massage instrument 100. The transmission assembly 30 can adopt gear transmission, belt transmission, or a linkage mechanism.
[0040] The angle detection component includes a signal emitting element and a sensing element. At least one of the two clamping heads 10 is provided with the signal emitting element, and the sensing element is arranged on the shell 110. The signal emitting element emits a signal to the sensing element while rotating with the clamping head 10. The sensing element detects the rotation angle of the clamping head 10 relative to the shell 110 according to the signal change.
[0041] In this embodiment, the control device 40 can send control instructions corresponding to the rotation angle of the clamping head 10 relative to the shell 110 to the driving motor 20 based on the rotation angle of the clamping head 10 relative to the shell 110. The rotation direction and angular displacement of the driving motor 20 are quickly and accurately adjusted to realize precise control of the opening and closing stroke of the clamping head 10.
[0042] According to the massage instrument 100, when the user starts the massage instrument 100, the control device 40 first initializes each component, including reading the initial angle value of the angle detection component, setting the initial state of the driving motor 20, etc. With the user operating the massage instrument 100, the chuck 10 starts to perform the opening and closing movement. The signal emitting element of the angle detection component rotates with the chuck 10, and continuously emits signals to the inductive element. The inductive element changes according to the received signal, and detects the rotation angle of the chuck 10 relative to the shell 110 in real time, and transmits the rotation angle information to the control device 40. The control device 40 calculates the current position and movement trend of the chuck 10 according to the received angle information. Then, according to the preset massage mode and user setting, the rotation direction and angular displacement of the driving motor 20 are determined to control the opening and closing stroke of the chuck 10. The control device 40 sends a control instruction to the driving motor 20, and the driving motor 20 adjusts the rotation direction and angular displacement according to the instruction, and drives the chuck 10 to perform the corresponding opening and closing movement through the transmission assembly 30. During the massage process, the angle detection component continuously monitors the rotation angle of the chuck 10, and the control device 40 continuously adjusts the operation of the driving motor 20 according to the angle information, so as to ensure that the opening and closing stroke of the chuck 10 meets the user's demand.
[0043] In the embodiment, the angle detection component includes but is not limited to an optical angle detection component and a magnetic encoder. Among them, taking the magnetic encoder as an example, the signal emitting element is a magnet, and when the chuck 10 rotates, the magnet also rotates together. The inductive element is an encoder, and the Hall element or the magneto-resistance element in the encoder can sense the magnetic field change generated by the magnet. When the magnet rotates, the magnetic field distribution around it will change. The Hall element or the magneto-resistance element is very sensitive to such magnetic field changes, and can generate corresponding electric signals according to the changes of the strength and direction of the magnetic field. Through the analysis and processing of these electric signals, the encoder can accurately detect the rotation angle of the chuck 10 relative to the shell 110.
[0044] In the embodiment, the control device 40 includes at least one of a microprocessor or a single-chip microcomputer.
[0045] In some embodiments of the utility model, please combine Figure 1 and Figure 3As shown, the massage device 100 further comprises a power supply circuit 50 for supplying power to the driving motor 20, and a current detection element 60 arranged in the power supply circuit 50, the current detection element 60 is electrically connected with the control device 40 and can detect the current value of the power supply circuit 50, and the control device 40 controls the driving motor 20 to operate according to the current value and the rotation angle. Specifically, since the current value delivered by the power supply circuit 50 to the driving motor 20 is positively correlated with the torque output by the driving motor 20, and the massage parts of the two clamping heads 10 may differ under different opening and closing angles, for example, the two clamping heads 10 can massage the waist under a large opening and closing angle, and the two clamping heads 10 can massage the neck under a small opening and closing angle, so the clamping force required under different opening and closing angles is also different. Therefore, by setting a corresponding current protection threshold under the opening and closing angle, when the current value detected by the current detection element 60 exceeds the current protection threshold corresponding to a certain opening and closing angle, the control device 40 can control the driving motor 20 to stop rotating or reverse rotation, so as to avoid the clamping force of the two clamping heads 10 from further increasing, and avoid injuring the massage parts, especially some small massage parts. Understandably, when the current value detected by the current detection element 60 is less than the current protection threshold corresponding to a certain opening and closing angle, the control device 40 can control to increase the current of the driving motor 20, so as to increase the clamping force of the two clamping heads 10, so that the massage device 100 can provide sufficient clamping force when massaging large muscle groups.
[0046] In the embodiment, the control device 40 can also generate a current threshold according to the maximum force value preset by the user in the app, and control the current of the control circuit to be below the threshold, to ensure that the preset force value is reached.

The rotating part 11 is provided in a gear structure, the second gear set 32 is meshed with the rotating part 11 of the two clamping heads 10 respectively, and the second gear set 32 transmits the power after deceleration by the first gear set 31 to the clamping head 10, to realize the opening and closing movement of the clamping head 10. In the embodiment, the rotating part 11 is provided with half a circle of gear teeth. In other embodiments, the rotating part 11 can also be provided with a whole circle of gear teeth.
[0048] Specifically, please refer to Figure 1 and Figure 2 As shown in the drawings, the first gear set 31 includes a worm wheel 311 and a worm 312 meshing with each other, and a first gear 313 coaxially connected with the worm wheel 311, the worm 312 is connected with the driving shaft of the driving motor 20, the second gear set 32 includes a second gear 321 and a third gear 322 coaxially connected, and a fourth gear 323 and a fifth gear coaxially connected, the second gear 321 is meshed with the first gear 313 and the fourth gear 323 respectively. The second gear 321 and the fourth gear 323 mesh with the first gear 313 and the fourth gear 323 respectively, which plays a role of intermediate transmission, and the tooth ratio of the second gear 321 and the fourth gear 323 is equal to 1, so the rotating speed of the second gear 321 and the fourth gear 323 is the same, which ensures the synchronous movement of the two clamping heads 10.

Among them, the tooth ratio of the second gear 321 and the first gear 313 is greater than 1, and the tooth ratio of the rotating part 11 and the third gear 322 is greater than 1, so that all the transmission assemblies 30 realize three-stage speed reduction, the first-stage speed reduction is the worm wheel 311 and the worm 312, the second-stage speed reduction is the first gear 313 and the second gear 321, and the third-stage speed reduction is the rotating part 11 and the third gear 322, which further reduces the rotating speed and increases the torque, so that the clamping head 10 can open and close at a suitable speed and force.

The power bank is equipped with a type-c interface and uses a USB PD (USB Power Delivery) fast charging protocol.
[0054] In some embodiments of the utility model, as shown in Figure 1As shown, the casing 110 is provided with a first receiving groove 1107 and a second receiving groove (not shown in the figure), and the two rotating parts 11 are respectively rotatably arranged in the first receiving groove 1107 and the second receiving groove. The two clamping arms 12 have a working state and a receiving state, and the two rotating parts 11 switch between the working state and the receiving state by rotating relative to the casing; in the working state, one chuck 10 is separated from the first receiving groove 1107, and the other chuck 10 is separated from the second receiving groove; in the receiving state, one chuck 10 is received in the first receiving groove 1107, and the other chuck 10 is received in the second receiving groove. The design of the receiving groove provides a storage space for the chuck 10 when not in use, so that the massage instrument 100 is more convenient to carry and store in the non-working state, and at the same time can protect the chuck 10 from being damaged.
[0055] Further, as shown, Figure 1 Figure 1 The casing 110 of the massage instrument 100 is in a long strip structure, which is convenient for the user to hold and operate the massage instrument 100. The long strip casing 110 can better adapt to the shape of the hand and provide a comfortable grip feeling.
[0056] The casing 110 has a first end face 1103 and a second end face 1104 opposite in the first direction, and the two rotating parts 11 are arranged in the second direction. The two clamping arms 12 can be driven by the driving motor 20 to extend out of the casing 110 and perform opening and closing movements from the first end face 1103. The driving motor 20 provides precise control and power for the movement of the clamping arm 12. The opening and closing movements of the clamping arm 12 can adapt to different massage parts and force requirements. For example, when the neck needs to be massaged, the clamping arm 12 can be opened to a certain angle and then clamped on the neck, and the force of the massage can be controlled by adjusting the opening and closing degree. Among them, the first direction is parallel to the length direction of the casing 110, and the second direction is perpendicular to the first direction.

In the working state, one clamping arm rotates relative to the casing, so that one clamp head 10 is separated from the first receiving groove 1107 and rotates to a position protruding from the first end surface 1103, and the other clamping arm rotates relative to the casing, so that the other clamp head 10 is separated from the second receiving groove and rotates to a position protruding from the first end surface 1103, at this time, the clamp head 10 can massage the body part. In the storage state, one clamp head 10 is stored in the first receiving groove 1107, and the other clamp head 10 is stored in the second receiving groove, so that the massage instrument 100 is more compact as a whole and occupies less space. When the driving motor 20 drives the two clamp heads 10 to switch from the working state to the storage state, the driving motor 20 drives the two clamp heads 10 to rotate in opposite directions through the transmission assembly 30, for example, the transmission assembly 30 drives one clamp head 10 to rotate counterclockwise by a certain angle, and the other clamp head 10 rotates clockwise by a certain angle, and then is respectively stored in the first receiving groove 1107 and the second receiving groove of the casing.
[0058] In some embodiments of the utility model, the casing 110 further defines a second mounting cavity 1110, and the battery pack 70 is mounted in the second mounting cavity 1110 and is electrically connected with the control device 40 and the driving motor 20 respectively, the battery pack 70, the driving motor 20 and the rotating part 11 are sequentially arranged along the first direction, and the control panel, the charge-discharge interface and the control knob are arranged on one side of the battery pack 70 along the second direction. In this way, the internal structure of the massage instrument 100 is more compact, and the space of the casing 110 is reasonably utilized.
[0059] If the two clamp heads are respectively stored in the first receiving groove and the second receiving groove, the step of controlling the two clamp heads to move to the upper dead point is to control the two clamp heads to move from the positions of the first receiving groove and the second receiving groove to the upper dead point respectively.
