Technical area

[0001] The present utility model relates to the technical field of massage devices, in particular to a double-grip drive device. State of the art

[0002] With the increase in people's demand for healthcare and quality of life, portable massagers have gradually become a hotspot in the market.

[0003] In existing technology, massage devices targeting specific sensitive areas of the human body often use simple vibration modules or mechanical reciprocating structures. Their functional modes are relatively simple, making it difficult to meet user demand for a diverse massage experience. For example, conventional devices can usually only achieve whole-body vibration or single-directional motion control, resulting in a massage effect that lacks a deep hierarchy and lacks a targeted effect. Content of the utility model

[0004] The present utility model provides a dual-grip drive device. By utilizing the structure of movable blocks independently controlled at the top and bottom, combined with the cooperative drive mechanism of multiple drive devices, it is possible to realize multiple switchable massage modes: separate movement of the movable blocks and synchronously coordinated movement of the two movable blocks.

[0005] The technical solutions used in this utility model are described as follows. A double-grip drive device comprises a rigid shell combined by mutual engagement. A drive device is mounted in the rigid shell. An eccentric is arranged at the output end of the drive device. The top of the eccentric is connected to a drive shaft. One side of the drive shaft is connected to opposing movable blocks. At least one vibration device is mounted in both movable blocks.

[0006] As a further improvement of the present utility model, the hard shell forms an outer casing body. The outer casing body is externally covered with a silicone sleeve. A battery is mounted in the silicone sleeve on one side of the outer casing body.

[0007] As a further improvement of the present utility model, both movable blocks are each connected to the drive shaft via a connecting element.

[0008] As a further improvement of the present utility model, the two connecting elements are each arranged at one end of the two movable blocks to drive the other end of the two movable blocks to move closer to or away from each other.

[0009] As a further improvement of the present utility model, one end of the two movable blocks moves in a manner that they approach each other or move away from each other, so that the two movable blocks perform a kneading massage motion.

[0010] As a further improvement of the present utility model, both ends of the connecting element are each pivotally connected to the movable block and the drive shaft.

[0011] As a further improvement of the present utility model, a motherboard is mounted on top of the hard shell. A magnetic charging pin is mounted on the motherboard.

[0012] As a further improvement of the present invention, a massage mechanism is mounted on the bottom of the silicone sleeve on one side of the outer casing body. The massage mechanism includes a small drive device. An eccentric block is arranged at the output end of the small drive device. A massage block is arranged on one side of the eccentric block. The massage block and the eccentric block are connected to each other via a movable rod and a spring.

[0013] As a further improvement of the present utility model, the main board is electrically connected to the battery, the small driving device, the driving device and the two vibrating devices.

[0014] Advantageous effects of the present utility model: due to the structure of the movable blocks independently controlled up and down, and in combination with the cooperative drive mechanism of multiple motors, the user can choose between different modes, such as moving the movable blocks separately and moving the two movable blocks synchronously in coordination, thereby performing targeted massage on different parts of the body, and providing a richer massage experience to satisfy the diverse massage needs of users.

[0018] In order to further clarify the technical problems to be solved in the present utility model, the technical solutions, and the advantageous effects, the present utility model is explained in more detail below with reference to the attached figures and exemplary embodiments. It should be understood that the exemplary embodiments described here serve only to explain the present utility model and are not intended to limit the present utility model.

[0019] The present utility model represents a double gripping drive device as in the Fig. 1 to 5, comprising a hard shell 3 combined by mutual engagement. A drive device 12 is mounted in the hard shell 3. An eccentric 11 is arranged at the output end of the drive device 12. The top of the eccentric 11 is connected to a drive shaft 10. One side of the drive shaft 10 is connected to opposing movable blocks 6. At least one vibration device 7 is mounted in both movable blocks 6.

[0020] As in the Fig. 1, Fig. 3, Fig. 4 and Fig. As shown in Figure 6, a massage mechanism 4 is mounted at the bottom inside the silicone shell 1 on one side of the outer casing body. The massage mechanism 4 includes a small drive device 401. An eccentric block 402 is arranged at the output end of the small drive device 401. A massage block 403 is arranged on one side of the eccentric block 402. The massage block 403 and the eccentric block 402 are connected to each other via a movable rod 404 and a spring 405.

[0021] As in the Fig. As shown in Figures 1 to 4, the hard shell 3 of the present utility model forms an outer casing body, the outer casing body having an overall L-shaped structure. The outer casing body is externally covered with a silicone shell 1. Two rings in the shape of an eight-shaped character are arranged at the lower end of the silicone shell 1. The arrangement of the silicone shell 1 not only improves the user's comfort in holding the device, but also achieves a certain anti-slip and buffer function, thereby protecting the internal mechanical structure from external impacts. The two eight-shaped rings and the rod-shaped silicone shell form a positioning part, which is positioned on at least one ring, at least one rod, or at least one handle.

[0022] In the present utility model, the two connecting elements 9 are each arranged at one end of the two movable blocks 6 to drive the other end of the two movable blocks 6 to move closer to or away from each other. One end of the two movable blocks 6 moves in such a way that they approach or move away from each other, so that the two movable blocks 6 perform a kneading massage motion.

[0023] As in the Fig. As shown in Figures 1 and 3 to 5, both movable blocks 6 of the present utility model are each connected to the drive shaft 10 via a connecting element 9. Both ends of the connecting element 9 are pivotally connected to the movable block 6 and the drive shaft 10. The arrangement of the connecting elements 9 allows the two movable blocks 6 to be movable by a certain angle with respect to the drive shaft 10, thus realizing independent control of the upper and lower movement.

[0024] As in the Fig. 1, Fig. 3 and Fig. As shown in Figure 4, a battery 2 is mounted in the silicone shell 1 on one side of the outer casing body. A main board 14 is mounted on top of the hard shell 3, and a magnetic charging pin 13 is mounted on the main board 14, which serves to provide power connection and charging functions. The main board 14 is electrically connected to the battery 2, the small driving device 401, the driving device 12, and the two vibration devices 7. The arrangement of the main board 14 realizes the control of the various motors and the management of the power supply, ensuring the stable operation of the device.

[0025] Operation: In the concrete implementation of the present utility model, the user can select and start various massage modes via the control buttons on the main board 14 or by connecting it to an external controller. When the mode in which the upper movable block 6 operates separately is selected, the main board 14 controls the corresponding vibration device 7, so that the movable block 6 vibrates or oscillates independently under the action of the connecting element 9 to massage the user.

[0026] Accordingly, when the mode in which the lower movable block 6 operates separately is selected, the main board 14 drives the vibration device 7 in the movable block 6 so that the movable block 6 vibrates or oscillates independently to massage the user.

[0027] When the mode in which the two moving blocks 6 operate synchronously and coordinated is selected, the main board 14 simultaneously controls the two vibration devices 7 and the drive device 12 to work together. The drive device 12 drives the two moving blocks 6 via the eccentric 11 and the drive shaft 10 to vibrate or oscillate them synchronously, providing the user with a more comprehensive and profound massage experience.

[0028] Furthermore, the massage mechanism 4 plays a supporting role in the massage throughout the device and can be started in any mode. By controlling the small drive device 401, the eccentric block 402 is driven to rotate. With the assisting action of the movable rod 404 and the spring 405, the massage block 403 is driven to continuously massage the user, increasing the variety and comfort of the massage.

[0029] Example: As shown in the Fig. As shown in Figures 7 to 9, the drive device is activated to start. The drive device 12 drives the two movable blocks 6 via the eccentric 11 and the drive shaft 10 to vibrate or oscillate them synchronously, providing the user with a more comprehensive and profound massage experience.

[0030] The above embodiments merely serve to explain the technical solutions of the present utility model and do not limit them. Although the present utility model has been explained in detail using the above embodiments, a person skilled in the art with basic knowledge should understand that they may further correct the technical solutions described in the above embodiments or replace some of the technical features with equivalent elements. Such changes or replacements should not cause the essence of the respective technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
