A belt

Abstract

A waist belt, when in use, is worn on the waist. A control device activates and deactivates the vibration and inflation / deflation components. The inflation / deflation components inflate and deflate the first and second airbag components, allowing the belt to massage the waist. Because the first and second airbags are parallel double-layered structures, their expansion thickness is greater than that of a single-layered airbag. Since the vibrator is located between the double-layered airbag structure and the waist, the greater deformation of the double-layered airbag structure allows for greater pressure on the vibrator. Furthermore, the easily deformable second airbag, when inflated, can enclose the less deformable vibrator, making the vibrator more stable and reducing energy loss during transmission to the waist. Because the second airbag fits snugly against the waist after inflation, the belt increases the support area, support force, and vibration range compared to the significantly smaller vibrator.

Description

Technical Field

[0001] This utility model relates to the field of health care protective equipment technology, specifically a waist belt. Background Technology

[0002] With the continuous development of society and the continuous improvement of living standards, people are paying more and more attention to their own health. Protective gear is the most common health care equipment, such as knee pads, elbow pads, and waist supports. These protective gear usually have the functions of sports protection, cold protection and warmth, and joint care, and are widely used in the fields of medical care. Taking waist belts as an example, there are many types of waist belts. Among them, waist belts with air bladders are particularly popular because they have the advantages of relieving joint pressure, providing support, and correcting posture.

[0003] Existing airbag waist belts often encounter the following problems during use. Specifically, the airbags in the waist belts are usually single-layered structures. During the cyclic inflation and deflation process, the maximum expansion thickness and massage pressure are limited, making it difficult to achieve deep muscle massage. Furthermore, due to the structure of the airbags themselves, such as airbags that are thinner at the edges and thicker in the middle after inflation, it is difficult to evenly conform to the curved waist of the human body, resulting in uneven pressure distribution on the waist and thus affecting the massage effect.

[0004] To enhance the massage effect, airbag waist belts with vibrators have appeared on the market. These belts typically place the vibrator on the side of the airbag closest to the waist. However, the vibrator has a certain thickness, while the deformation of a single-layer airbag is limited. This makes it difficult for the airbag to fit snugly against the waist, resulting in reduced support and massage effect. Furthermore, this design means that the vibrator only bears force at one end of the airbag and the other end of the waist, causing it to easily wobble and shift during vibration, affecting the massage effect. In addition, the size of the vibrator is significantly smaller than the size of the airbag, resulting in a smaller vibration massage range and making it inconvenient to use. Utility Model Content

[0027] (III) Beneficial Effects

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] Because the first and second airbags are parallel double-layer airbag structures, they have a greater expansion thickness and a wider range of massage pressure adjustment compared to single-layer airbags.

[0030] Since the vibrator is located between the second airbag and the waist, the inflation of the first and second airbags can generate greater pressure on the vibrator. Furthermore, the easily deformable second airbag can enclose the less deformable vibrator after inflation, thus effectively preventing the vibrator from swaying back and forth, making it more stable, and reducing the loss of vibration energy during transmission to the waist, thereby improving the vibration transmission rate of the vibrator.

[0031] Since the second airbag can fit snugly against the waist after inflation, it can increase the support area and force of the waist belt on the waist compared to the significantly smaller vibrator. In addition, the vibration of the vibrator can be transmitted to the second airbag and the waist in sequence, thus increasing the vibration range of the waist belt.

[0032] In summary, by using this belt, the overall expansion thickness of the airbag can be increased, the position of the vibrator can be stabilized and the vibration transmission rate of the vibrator can be improved, and the support area, support force and vibration range of the belt on the human waist can also be increased.

[0050] 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.

[0051] See appendix Figure 1 - Appendix Figure 7 and appendix Figure 14 Appendix Figure 15 This utility model discloses a waist belt, including a main body 1 made of flexible material for wrapping around the waist of a human body. The main body 1 is provided with a control device 6 and a first airbag assembly 2. The first airbag assembly 2 includes at least one inflatable first airbag 21. Each first airbag 21 is provided with a second airbag assembly 3 on the side near the waist of the human body. The second airbag assembly 3 includes at least one inflatable second airbag 31. Each second airbag 31 is provided with a vibration assembly 4 on the side near the waist of the human body. Each vibration assembly 4 includes at least one vibrator 41. The main body 1 is also provided with an inflation / deflation assembly 5 and a control device 6. The inflation / deflation assembly 5 is used to control the inflation / deflation of the first airbag assembly 2 and the second airbag assembly 3. The control device 6 is used to control the start and stop of the vibration assembly 4 and the inflation / deflation assembly 5.

[0052] In actual use, the main body 1 is wrapped around and secured to the designated area of ​​the waist. Then, the control device 6 controls the start and stop of the vibrator 41 in the vibration assembly 4 and the inflation / deflation assembly 5. The inflation / deflation assembly 5 controls the inflation and deflation of the first airbag 21 in the first airbag assembly 2 and the second airbag 31 in the second airbag assembly 3, thus allowing the belt to massage the waist. Because the first airbag 21 and the second airbag 31 are parallel double-layered airbag structures, they have a greater expansion thickness and a wider range of massage pressure adjustment compared to single-layered airbags. Since the vibrator 41 is located between the second airbag 31 and the waist, the inflation of the first airbag 21 and the second airbag 31 can generate greater pressure on the vibrator 41, and the easily deformable second airbag 31 can also be inflated. When inflated, the belt can enclose the non-deformable vibrator 41, effectively preventing it from wobbling back and forth and making it more stable. It also reduces the loss of vibration energy during transmission to the waist, thereby improving the vibration transmission rate of the vibrator 41. Since the second airbag 31 can fit snugly against the waist after inflation, it increases the support area and force of the belt on the waist compared to the significantly smaller vibrator 41. In addition, the vibration of the vibrator 41 can be transmitted sequentially to the second airbag 31 and the waist, thus increasing the vibration range of the belt. In summary, by using this belt, the overall expansion thickness of the airbag can be increased, the position of the vibrator 41 can be stabilized and the vibration transmission rate of the vibrator 41 can be improved, and the support area, force and vibration range of the belt on the waist can also be increased.

[0053] See appendix Figure 3 - Appendix Figure 7 It should be noted that since this application does not limit the specific number and installation position of the first airbag 21, the second airbag 31 and the vibrator 41, they can be flexibly designed according to actual needs. For example, since the middle of the lower back of the human body is a concave structure and airbags usually cannot massage this area, two first airbags 21 can be selected and respectively correspond to the left and right sides of the lower back of the human body to avoid wasting resources. Two second airbags 31 are also selected and respectively set on the two first airbags 21 to avoid the structure being too complicated. Similarly, two vibrators 41 are selected and respectively set in the middle of the two second airbags 31 so that the second airbags 31 can more evenly and thoroughly wrap the vibrator 41.

[0054] See appendix Figure 8 It should be noted that the type of vibrator 41 is not limited in this application, and can be flexibly selected according to actual needs. In this embodiment, the vibrator 41 is preferably an eccentric vibrator.

[0055] See appendix Figure 5 - Appendix Figure 7Furthermore, a groove 311 corresponding to the vibrator 41 can be provided on the second airbag 31 so that the second airbag 31 can more evenly and thoroughly wrap the vibrator 41.

[0056] Based on the above solution, since this belt has both airbag massage and vibration massage functions, it has three usage modes, specifically:

[0057] 1. Using only airbag massage, during use, the first airbag assembly 2 and the second airbag assembly 3 are cyclically inflated and deflated to generate cyclic pressure waves and simulate the physical massage action of "pressing and releasing". The massage speed can be adjusted according to the inflation and deflation speed, and the massage pressure can be adjusted according to the amount of inflation. Gradient pressure can be formed during the massage to promote blood flow and act on deep muscles. Moreover, the noise is relatively low during use, the massage action is more gentle and smooth, and the comfort is higher.

[0058] 2. Vibration massage only: When using it, inflate the first airbag assembly 2 and the second airbag assembly 3 and maintain this state. At this time, the vibration assembly 4 will be pressed against the waist. Activating the vibrator 41 will generate high-frequency mechanical vibration. The vibration mode is relatively simple and can simulate the physical massage action of "tapping or kneading". The massage speed can be adjusted according to the vibration frequency of the vibrator, and the massage pressure can be adjusted according to the vibration amplitude of the vibrator. During the massage, the energy is concentrated on the local surface tissue, which can stimulate muscles and nerve endings. The noise is relatively loud during use, the massage action is more intense, and the vibration is stronger.

[0059] 3. Simultaneous use of airbag massage and vibration massage: When using, inflate the first airbag assembly 2 and the second airbag assembly 3 and press the vibration assembly 4 firmly against the waist. Then, without affecting the fixation of the vibration assembly 4, cyclically inflate and deflate the first airbag assembly 2 and the second airbag assembly 3, and start the vibrator 41 to perform high-frequency mechanical vibration. In this vibration mode, compared with using airbag massage only, the massage intensity can be increased and the massage modes can be added, and the waist can be continuously massaged, resulting in faster and better effects. Compared with using vibration massage only, the massage range can be increased and the massage modes can be added, and the massage intensity can present a gradient change, resulting in greater comfort.

[0060] See appendix Figure 1 - Appendix Figure 3In order to enable the main body 1 to wrap around the waist of the human body, the following design is made in this embodiment. Specifically, the main body 1 includes an inner fabric cover 101 and an outer fabric cover 102. The inner fabric cover 101 is located on the side of the main body 1 close to the waist of the human body. The inner fabric cover 101 is basically long and has a Velcro side 103 on the side close to the waist of the human body. The outer fabric cover 102 is located on the side of the main body 1 away from the waist of the human body and is connected to the inner fabric cover 101. The outer fabric cover 102 is basically long and has a Velcro side 104 on the side away from the waist of the human body. The inner fabric cover 101 and the outer fabric cover 102 can be fastened together by the Velcro side 103 and the Velcro side 104, thereby wrapping and fixing the main body 1 around the waist of the human body. The first airbag assembly 2, the second airbag assembly 3 and the vibration assembly 4 are all arranged between the outer fabric cover 102 and the inner fabric cover 101.

[0061] Through the design of the above structure, the inner fabric cover 101 can be wrapped around the waist, and then the Velcro side 103 on the inner fabric cover 101 can be fastened to the Velcro side 104 on the outer fabric cover 102, thus wrapping and fixing the main body 1 around the waist. Since both the Velcro side 103 and the Velcro side 104 are simple planar structures and can be deformed, they will not affect the structure and thickness of the main body 1 in the unused state, nor will they affect the ability of the main body 1 to be wrapped and deformed during use. Since the Velcro side 103 and the Velcro side 104 can be fastened by pressing and unfastened by pulling, they are easier to assemble and disassemble and more convenient to use. Since both the Velcro side 103 and the Velcro side 104 have a certain length, and any part of the Velcro side 103 and the Velcro side 104 can be fastened, the length of the main body 1 after wrapping can be flexibly adjusted according to the actual waist circumference of the human body, making it more applicable and more comfortable.

[0062] It should be noted that this application does not limit the structure, material, size, color, or detachable connection method of the main body 1 when it is wrapped and fixed. The above-mentioned fabric cover structure and Velcro connection are only illustrative examples. For example, snaps, buckles, etc. can also be used for detachable connection. In addition, this embodiment does not limit the Velcro sub-side 103 and the Velcro mother-side 104. They can be designed according to actual needs. For example, the Velcro sub-side 103 can be designed as a hook side and the Velcro mother-side 104 can be designed as a rough side. In this case, the hook side can be designed to avoid scratching the arm with the hook side facing outward. Alternatively, the Velcro sub-side 103 can be designed as a rough side and the Velcro mother-side 104 can be designed as a hook side. In this case, the hook side can be designed to avoid scratching the waist with the hook side facing inward.

[0063] See appendix Figure 3 - Appendix Figure 7When the first airbag assembly 2 includes at least two first airbags 21, the following design is made in this embodiment: specifically, the different first airbags 21 are interconnected.

[0064] The above-described structure design balances the air pressure within the different first airbags 21 and enhances stability. It also reduces the number of pipes required to deliver gas to the first airbags 21, thereby simplifying the structure and reducing the overall weight of the belt.

[0065] When the second airbag assembly 3 includes at least two second airbags 31, the following design is made in this embodiment: specifically, the different second airbags 31 are interconnected.

[0066] The above-described structure design balances the air pressure within the different second airbags 31 and enhances stability, ensuring uniform force distribution on the vibrator 41 and the waist. It also reduces the number of tubes required to deliver gas to the second airbags 31, thereby simplifying the structure and reducing the overall weight of the belt.

[0067] It should be noted that the above-mentioned "different first airbags 21 are interconnected, and different second airbags 31 are interconnected" includes multiple connection methods, specifically:

[0068] 1. Different first airbags 21 are directly connected, and different second airbags 31 are directly connected. At this time, the first airbag 21 and the corresponding second airbag 31 can be connected to each other or not connected to each other.

[0069] 2. Different first airbags 21 are directly connected, and the first airbag 21 and the second airbag 31 are interconnected, thereby indirectly connecting the different second airbags 31. This connection method is used in this embodiment, which can be referred to in the appendix. Figure 5 and attached Figure 6 ;

[0070] 3. Different second airbags 31 are directly connected, and the first airbag 21 and the second airbag 31 are interconnected, thereby making different first airbags 21 indirectly connected.

[0071] See appendix Figure 5 and attached Figure 6 Furthermore, in this embodiment, the following design is also included: specifically, the first airbag 21 and the second airbag 31 are interconnected to improve the cushioning performance of the waist belt.

[0072] Through the design of the above structure, during the vibration of the vibrator 41, the gas in the second airbag 31 can flow to the first airbag 21, which can effectively prevent the airbag from rupturing due to sudden increase in local pressure or overload. Moreover, the gas will enhance energy dissipation during the flow, absorb impact better, and have stronger cushioning performance, resulting in less vibration in the non-massage area of ​​the belt and greater wearing comfort.

[0073] See appendix Figure 3 - Appendix Figure 7 To enhance the support effect of the waist belt, the following design is implemented in this embodiment: Specifically, the first airbag assembly 2 and the second airbag assembly 3 are located in the middle of the main body 1, which can support the back of the waist by inflation and massage the back of the waist by cyclic inflation and deflation; it also includes a third airbag assembly 7, which is located on the main body 1. The third airbag assembly 7 includes at least one set of inflatable third airbags 71, and each set of third airbags 71 includes two third airbags 71 and is symmetrically arranged relative to the first airbag assembly 2.

[0074] Through the design of the above structure, the third airbag component 7 can support the left and right sides of the human waist after inflation, correct sitting posture, and also massage the left and right sides of the human waist through cyclic inflation and deflation.

[0075] Furthermore, different third airbags 71 can be interconnected to make the force on the waist more even. In addition, the number of tubes required to deliver gas to the third airbags 71 can be reduced, thereby simplifying the structure and reducing the overall weight of the belt.

[0076] See appendix Figure 3 and appendix Figure 9 - Appendix Figure 11 To enable the inflation / deflation assembly 5 to inflate / deflate the first airbag assembly 2 and the second airbag assembly 3, the following design is implemented in this embodiment: Specifically, the inflation / deflation assembly 5 includes an air pump 51, a multi-port connector 52, and multiple solenoid valves 53. The air pump 51 has both blowing and suction functions and is electrically connected to the control device 6 to control its start / stop and function switching. The multi-port connector 52 includes an air inlet 521 and multiple air outlets 522. The air inlet 521 is connected to the air pump 51 via a first air supply pipe 54, and the air outlets 522 are connected to second air supply pipes 55. The multiple solenoid valves 53 are respectively installed on the multiple second air supply pipes 55 to control their opening and closing. All the multiple solenoid valves 53 are connected to the control device 6. Device 6 is electrically connected and used to control the start and stop of solenoid valve 53; the interconnected first airbag 21, the interconnected second airbag 31, the interconnected third airbag 71, the interconnected first airbag 21 and second airbag 31, the interconnected first airbag 21 and third airbag 71, the interconnected second airbag 31 and third airbag 71, and the interconnected first airbag 21, second airbag 31 and third airbag 71 can all form a connected chamber; the non-connected first airbag 21, non-connected second airbag 31 and non-connected third airbag 71 can all form an independent chamber; the connected chambers and independent chambers are respectively connected to different second air supply pipes 55; at least one second air supply pipe 55 is connected to each connected chamber and each independent chamber.

[0077] With the above structural design, the gas pressure of each connected chamber and each independent chamber can be controlled independently; and with the same gas flow rate in each second gas supply pipe 55, the gas filling and discharging speed of the connected chamber and the independent chamber can be controlled by the number of connected second gas supply pipes 55.

[0078] Furthermore, the air pump 51 can be a vortex air pump, which has both blowing and sucking functions, making it convenient for the air pump 51 to inflate the airbag, that is, to input gas into the airbag, or to deflate the airbag, that is, to output gas from the airbag.

[0079] Based on the above scheme, the more chambers that can independently control air pressure, the easier it is to flexibly adjust the air pressure of chambers corresponding to different parts of the waist, with a higher degree of freedom, which is suitable for people with high sensitivity or lumbar deformities.

[0080] See appendix Figure 3 In order to enrich the health care function of the belt, the following design is made in this embodiment. Specifically, the main body 1 is provided with a heating component 8 for physiotherapy of the human waist. The heating component 8 is detachably connected to the control device 6.

[0081] Furthermore, the heating element 8 is a heating plate, which is thin and deformable, and does not affect the appearance and structure of the main body 1 or its ability to be wound and deformed. It also has the advantages of easy installation, no pollution, and long service life.

[0082] See appendix Figure 3 In order to enhance the supporting effect of the main body 1, the following design was carried out in this embodiment. Specifically, the main body 1 is provided with an elastic element 9.

[0083] Through the above structural design, the main body 1 can be more tightly wrapped around the waist, and the design of the elastic element 9 increases the structural strength of the main body 1, making it less prone to deformation when the main body 1 is twisted and bent at the waist, thereby increasing the support force and making its support effect better.

[0084] Furthermore, the aforementioned elastic element 9 can be made of PP sheet, memory spring strip, etc.

[0085] See appendix Figure 1 - Appendix Figure 3 Based on the above scheme, the following design is also made in this embodiment. Specifically, it also includes a connecting seat 10, which is made of rigid material and is located on both sides of the elastic member 9, and the control device 6. The control device 6 includes a housing 61, and the connecting seat 10 and the housing 61 are fixedly connected.

[0086] Through the above structural design, the control device 6 is essentially fixed to the elastic element 9 with a certain degree of hardness. Compared to being directly fixed to the relatively soft main body 1, this method makes the connection of the control device 6 more secure, and the part of the main body 1 corresponding to the control device 6 is subjected to less force, making it less likely to be torn or damaged due to pulling.

[0087] It should be noted that the "fixed connection" between the connecting seat 10 and the housing 61 includes detachable and non-detachable connections. Detachable connections can be made by means of threaded connection, snap-fit ​​connection, magnetic connection, etc., while non-detachable connections can be made by means of adhesive, etc. In this embodiment, threaded connection is preferred.

[0088] See appendix Figure 1 Appendix Figure 12 and attached Figure 13 Furthermore, in this embodiment, the control device 6 is designed as follows: Specifically, the control device 6 includes a housing 61, a touch screen 62, a circuit board 63, a power supply 64, a switch 65, and a charging port 66. The housing 61 includes a detachably connected upper shell 611 and a lower shell 612. The lower shell 612 is located between the upper shell 611 and the main body 1 and is connected to the connecting seat 10. The touch screen 62 is disposed outside the housing 61. The circuit board 63 and the power supply 64 are disposed inside the housing 61. The switch 65 and the charging port 66 are disposed on the circuit board 63 and one end extends out of the housing 61, allowing the user to perform switching and charging operations outside the housing 61. In addition, the vibrator 41, air pump 51, solenoid valve 53, heating assembly 8, touch screen 62, power supply 64, and switch 65 are also included.
