Description

Technical Field

[0001] This utility model belongs to the field of physiotherapy equipment technology, specifically relating to a back-mounted multidimensional vibration device. Background Technology

[0002] Vibration therapy uses mechanical vibrations to stimulate human tissues, improving blood circulation, relieving muscle fatigue, and promoting tissue repair. Initially applied in sports rehabilitation, this technology has now expanded to chronic pain management and post-operative recovery. The core principle is to generate mechanical vibrations of a specific frequency using a motor, which are then transmitted through a conductive device to act on superficial or deep tissues to achieve therapeutic effects.

[0003] The prior art discloses a Chinese utility model patent with application number 202121481672.0, which discloses a cushion-type vibration therapy device structure, including a cylindrical motor housing. A circuit board fixing top cover is snapped onto one end of the cylindrical motor housing. Two soft pad fixing strips are symmetrically welded laterally to the bottom of the cylindrical motor housing, and soft pads are fixed between the two soft pad fixing strips by screws. The cylindrical motor housing and the circuit board fixing top cover of this utility model are connected by snapping, and the soft pads and soft pad fixing strips are fixed by screws. This avoids the use of seam filler, thereby avoiding the risk that the filler is easily corroded by the oily lubricant used for massage. In addition, the cylindrical design of the cylindrical motor housing and the installation of soft pads solve the problem of cracking at the joint caused by long-term vibration, and at the same time reduce the risk of the housing cracking due to drops.

[0004] The existing technologies mentioned above also have the following shortcomings: 1. High-amplitude impacts can easily cause capillary rupture and soft tissue edema; 2. Vibration energy is concentrated in the surface muscles and cannot penetrate into the deep bones and vascular network, thus failing to effectively improve microcirculation; 3. There is a strong mechanical impact sensation, resulting in a poor user experience. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example Please see Figures 1-6 This embodiment provides the following technical solution: a back-to-back multidimensional vibration device, including a vibration host 2 and a vibration therapy pad 1. The vibration host 2 and the vibration therapy pad 1 are connected and cooperate to form a vibration main structure. The vibration host 2 and the vibration therapy pad 1 are fixedly connected by a first fastening screw 9.

[0020] A first leather covering layer 4 is fixedly connected to the outer surface of the vibration host 2, and a second leather covering layer 6 is fixedly connected to the outer surface of the vibration therapy pad 1. The first leather covering layer 4 and the second leather covering layer 6 improve the comfort, durability, aesthetics and hygiene of the device.

[0021] The back of the second leather covering layer 6 is fixedly connected with a fixing strap 5. The fixing strap 5 can fix the device to the back of the human body, so that the device fits closely to the back of the human body and improves the massage effect.

[0022] The vibration host 2 includes a housing and a motor 16. The motor 16 is fixedly connected to the housing via shock absorbers 18. Two swing blocks 15 are fixedly connected to the output shafts at both ends of the motor 16. The two swing blocks 15 are asymmetrically installed to generate multi-dimensional vibrations in the X, Y, and Z directions. Multiple shock absorbers 18 are symmetrically fixedly connected to the outer surface of the motor 16. Through the motor 16 and the swing blocks 15, the vibration host 2 generates three-dimensional helical vibrations in the X, Y, and Z directions, and then transmits the vibrations to the vibration therapy pad 1. The amplitude is low, but the penetration force can reach soft tissues, muscles, and bones. Moreover, blood circulation is significantly improved, overcoming the problem that most massage products are prone to tissue damage and symptom aggravation due to high amplitude, thus improving the user experience.

[0023] In some embodiments, the motor 16 is a brushless DC motor 16, which drives the swing block 15 to move in a three-dimensional spiral trajectory, generating a composite vibration vector. Compared with the motion structure of the traditional rotating eccentric wheel, the vibration direction achieves dynamic superposition of the X, Y, and Z axes, thereby improving the treatment coverage area.

[0024] The vibration therapy pad 1 includes an elastic base layer and a buffer layer. One end of the elastic layer is fixedly connected to the outer shell body, and the buffer layer is fixedly connected to the elastic base layer. In some embodiments, the elastic base layer is a nickel alloy elastic pad 7, and the buffer layer is a high-density sponge 8. In the structural combination of the vibration host 2 and the vibration therapy pad 1 pressing the nickel alloy elastic pad 7 together with the first fastening screw 9, a directional attenuation gradient of vibration energy is formed. Moreover, under the combined action of the nickel alloy elastic pad 7 and the high-density sponge 8, the vibration wave forms a multi-band superposition effect, breaking through the limitation of traditional single-frequency vibration.

[0025] The outer shell body includes a male outer shell 11, a female outer shell 17, a first outer shell plug 12, and a second outer shell plug 21. The male outer shell 11 and the female outer shell 17 cooperate to form a sealed cavity with open ends. The male outer shell 11 and the female outer shell 17 are fixedly connected by a second fastening screw 14. In some embodiments, the end face of the male outer shell 11 is provided with a trapezoidal tenon, and the end face of the female outer shell 17 is provided with a corresponding trapezoidal mortise to ensure precise alignment in the axial and radial directions.

[0026] Both the male outer shell 11 and the female outer shell 17 are fixedly connected to the inner walls of the outer shell. In some embodiments, multiple reinforcing ribs 13 are provided, and the multiple reinforcing ribs 13 are arranged in a radial grid pattern to avoid stress concentration and avoid resonance frequency.

[0027] In some embodiments, the male outer shell 11, the female outer shell 17, and the reinforcing rib 13 are all square structures. The outer shell body adopts a right-angle structure and modular design, which improves the overall strength of the outer shell body. Its planar contact surface and angular structure can effectively disperse mechanical stress. Especially when subjected to high-frequency vibration or impact loads, the stress distribution is more uniform, reducing the risk of local stress concentration.

[0028] The two ends of the sealed cavity are respectively detachably connected to a first outer shell plug 12 and a second outer shell plug 21. In some embodiments, the first outer shell plug 12 can be detachably connected to the outer shell body through a guide buckle structure, while the second outer shell plug 21 can be engaged with the outer shell body through a spring buckle, which can quickly lock the second outer shell plug 21.

[0029] A mounting base 19 is fixedly connected inside the outer casing. A circuit board 20 is fixedly connected to the mounting base 19. The output power line on the circuit board 20 passes through the wire groove 10 on the outer casing and is connected to the motor 16. The input power line 3 on the circuit board 20 passes through the second outer casing plug 21 and is connected to the power supply. The motor 16 can be controlled to work by controlling the circuit board 20.

[0030] It also includes a remote controller 22 for operating the motor 16. In some embodiments, the remote controller 22 is equipped with a controller, which integrates a wireless communication module and a mode programming module. It can preset three modes and remotely control the device to change its working mode. By changing the frequency of the motor 16, the amplitude of the device can be changed, which can better adapt to different working environments and work requirements.

[0031] The working principle of this utility model is as follows: When in use, the input power cord 3 is connected to the power supply, and the vibration therapy pad 1 is fixed to the back of the body using the fixing strap 5. The switch of the remote control 22 is turned on, and the control buttons on the remote control 22 can be controlled to make the motor 16 drive the swing block 15 to work. The vibration host 2 generates multi-dimensional vibration in the X, Y, and Z directions, thereby transferring the vibration energy to the vibration therapy pad 1. The vibration therapy pad 1 then transfers the vibration energy to the human body, thereby achieving the purpose of massage. According to the massage needs, the working mode of the motor 16 can be adjusted so that the device is suitable for different massage needs.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
