Description

TECHNICAL FIELD

[0002] With the improvement of people's living standards and the continuous enhancement of health consciousness, traditional Chinese medicine therapy gradually attracts attention in modern life, and moxa -moxibustion therapy is concerned due to its unique warm effect and the effect of regulating human meridian. To meet the requirements of modern people for moxa -moxibustion treatment convenience, comfort and multifunction, various forms of moxa -moxibustion equipment emerge in an endless stream, and moxa -moxibustion sofa is a kind of health care equipment integrating traditional therapy and modern ergonomics design under this background.

[0003] The common moxa -moxibustion sofa on the market is mainly composed of sofa body, backrest adjusting mechanism and moxa -moxibustion device. Among them, the sofa body is generally used as the sitting and lying platform of the user, and the backrest adjusting mechanism realizes the adjustment of the inclination angle of the back through mechanical or electric drive mode, so as to facilitate the user to adjust the sitting or semi-lying posture according to the treatment needs. At the same time, the moxa -moxibustion device is usually arranged on the backrest or the side of the sofa, and the local heating and warm conduction are used to moxa -moxibustion treatment of specific parts of the human body. Although these products meet the needs of users for moxa -moxibustion treatment convenience to some extent, there are still some problems in actual use as follows:

[0004] (1) Most of the existing moxa -moxibustion sofas focus on backrest adjustment design, mainly focusing on the comfort of the user's back and the heating effect of the moxa -moxibustion part, and less attention is paid to the leg support problem. For the user in moxa -moxibustion state for a long time, only the backrest adjustment without effective leg support can easily cause the user to feel leg fatigue, suspended discomfort and other phenomena, thereby affecting the overall treatment effect and use experience. Some products try to use external foot stool or independent leg support design to improve the leg support problem, but such design often has the defects of separation from the main structure, additional adjustment position and large space occupation during use, and lacks flexible adjustment function.

[0005] (2) The existing moxa -moxibustion sofa mainly focuses on providing moxa -moxibustion treatment function, and ignores other needs of the user during moxa -moxibustion process, and the function is relatively single. In the market, there are some sofa products combining moxa -moxibustion and massage functions, but these products often simply stack moxa -moxibustion and massage devices together, lack reasonable structure design and cooperative working mechanism, and usually use complex mechanical structure or electric drive system to realize massage and backrest adjustment function, which not only increases the manufacturing cost and maintenance difficulty of the product, but also may cause failure or damage during use, affecting the normal use of the user. At the same time, complex operation interface and cumbersome adjustment steps will also cause the user's confusion and inconvenience.

[0053] The moxibustion sofa with a leg rest and an adjustable backrest disclosed in the present application realizes the synchronous adjustment of the back and leg support through an integrated mechanical linkage mechanism, which not only effectively reduces the possible coordination errors between independent adjustment components, but also reduces the complexity and failure rate of the overall system, while greatly simplifying the user operation process. The problems of insufficient leg support and single function of traditional moxibustion sofas are effectively solved, and the user can obtain more comprehensive support and comfortable experience during a long moxibustion process. The structure is compact, the operation is convenient, and the use is reliable.

[0054] As a preferred example of the present application, the linkage assembly 2 comprises a second linkage 202, a fourth linkage 204, one end of the second linkage 202 and the fourth linkage 204 being hinged to the base assembly 100, the other end of the second linkage 202 being hinged to the second connecting member 4 through a third linkage 203, the other end of the fourth linkage 204 being hinged to the second connecting member 4 through a fifth linkage 205, a first linkage 201 being hinged on the second linkage 202, the first linkage 201 being hinged to a first connecting member 3, the first connecting member 3 being hinged to the base assembly 100, when the second linkage 202 and the fourth linkage 204 swing away from the side of the backrest assembly 200 under the action of the driving device 1, the backrest assembly 200 is driven to rotate backward, the leg rest assembly 300 is driven to rotate upward, on the contrary, when the second linkage 202 and the fourth linkage 204 swing toward the side of the backrest assembly 200 under the action of the driving device 1, the backrest assembly 200 is driven to rotate forward, the leg rest assembly 300 is driven to rotate downward.

[0055] The setting discloses a set of carefully designed connecting rod assemblies 2 to realize synchronous rotation adjustment of the backrest assembly 200 and the leg support assembly 300, the connecting rod assemblies 2 include second connecting rods 202 and fourth connecting rods 204, one end of the two connecting rods is firmly fixed on the base assembly 100 through hinged connection, and the other end is hinged with the second connecting piece 4 through the third connecting rod 203 and the fifth connecting rod 205, respectively, and the first connecting rod 201 is also hinged on the second connecting rod 202, the first connecting rod 201 is connected with the first connecting piece 3 through hinged connection, and the first connecting piece 3 is hinged and fixed with the base assembly 100, under the action of the driving device 1, when the second connecting rod 202 and the fourth connecting rod 204 swing away from the side of the backrest assembly 200, the first connecting rod 201 and the first connecting piece 3 are driven to work cooperatively through the close hinged connection between the connecting rods, so that the backrest assembly 200 rotates backward along the predetermined trajectory, and the leg support assembly 300 rotates upward due to the linkage effect, realizing effective support for the legs; when the driving device 1 acts in reverse, the second connecting rod 202 and the fourth connecting rod 204 swing towards the side close to the backrest assembly 200, and the backrest assembly 200 rotates forward to restore the upright state through the same mechanical linkage transmission effect, and at the same time, the leg support assembly 300 rotates downward to be retracted, the whole adjustment process relies on the pre-designed hinged connection and connecting rod structure to realize the coordinated cooperation between the movement parts, and the user can complete the stable switching from the sitting position to the lying position through the simple control switch, so that the perfect combination of convenient operation, accurate adjustment, durability and comfort in long-term use is realized on the premise of ensuring the stability of the equipment structure and the safety of the operation. In the example of the present application, the above-mentioned synchronous driving adjustment function can be realized by other four connecting rods, five connecting rods and other complex connecting rod mechanisms, and the above-mentioned exemplary description is the preferred example of the present application.

[0056] The present application discloses a five connecting rod synchronous adjustment connecting rod assembly 2, so that the backrest assembly 200 rotates backward while the leg support assembly 300 rotates upward synchronously under the action of the connecting rod mechanism, realizing smooth and smooth switching between the sitting position and the lying position, the structure is compact, the movement path is reasonable, and the operation complexity and fault risk brought by traditional independent adjustment of multiple parts are simplified.

[0057] As a specific example of the present application, the second connecting rod 202 is arranged at the rear side of the fourth connecting rod 204, the upper end of the second connecting rod 202 is hinged to the base assembly 100 through the seventh rotating shaft 2012, the lower end of the second connecting rod 202 is hinged to one end of the third connecting rod 203 through the sixth rotating shaft 2011, the other end of the third connecting rod 203 is hinged to the second connecting piece 4 through the third rotating shaft 208, the upper end of the fourth connecting rod 204 is hinged to the base assembly 100 through the fifth rotating shaft 2010, the lower end of the fourth connecting rod 204 is hinged to one end of the fifth connecting rod 205 through the second rotating shaft 207, the other end of the fifth connecting rod 205 is hinged to the second connecting piece 4 through the first rotating shaft 206, the third connecting rod 203 and the fourth connecting rod 204 are hinged at a position close to the middle part through the fourth rotating shaft 209, the front section of the first connecting rod 201 is hinged to the second connecting rod 202 at a position close to the middle part through the eighth rotating shaft 2013, the rear end of the first connecting rod 201 is hinged to the first connecting piece 3 through the ninth rotating shaft 2014, the first connecting piece 3 is hinged to the base assembly 100 through the tenth rotating shaft 2015, and the tenth rotating shaft 2015 is located above the ninth rotating shaft 2014.

[0058] The arrangement further optimizes the connecting rod structure and rotating shafts in the connecting rod assembly 2, by reasonably configuring the second connecting rod 202, the fourth connecting rod 204, and the third connecting rod 203, the fifth connecting rod 205, and the first connecting rod 201 connected thereto, the synchronous linkage adjustment of the backrest assembly and the leg support assembly is realized, and the smoothness of the movement track and the overall rigidity of the structure during adjustment are also maintained, thereby effectively avoiding the shaking or uncoordinated problems that may occur in the traditional single-point support or multiple independent driving modes. When the user adjusts the sitting posture or the semi-laying posture, each rotating shaft can provide sufficient and uniform mechanical support during linkage, so that the waist and back and the legs can obtain comfortable and reasonable support at different angles, thereby reducing the fatigue and pressure on the body during long-time sitting or resting.

[0059] As a preferred example of the present application, the link assembly 2 is provided in two groups, the front ends of the two groups of link assemblies 2 are respectively connected to the leg support assembly 300 through a second connecting piece 4, the rear ends of the two groups of link assemblies 2 are respectively connected to the backrest assembly 200 through a first connecting piece 3, and the two groups of link assemblies 2 are driven by a set of driving devices 1.

When the driving device is started, it will output power internally to make the two groups of link assemblies produce synchronous and coordinated swinging, thereby driving the leg support assembly 300 and the backrest assembly 200 to rotate upward or backward by a corresponding angle, respectively. The whole movement process adopts the mode of multi-point support and multi-joint shaft cooperation to ensure balanced stress and accurate angle transmission, and during movement, the two groups of link assemblies can cooperate with each other to make the adjustment action more smooth and stable, while reducing the shaking or imbalance phenomenon caused by single-sided transmission.

[0060] As a preferred example of the present application, a first connecting crossbar 11 is arranged between the two first connecting pieces 3, and / or a second connecting crossbar 13 is arranged between the two link assemblies 2, and the driving device 1 can drive the first connecting crossbar 11 or the second connecting crossbar 13 to move, thereby driving the backrest assembly 200 and the leg support assembly 300 to rotate. In the example of the present application, as shown in Figure 7 、 Figure 8 a first connecting crossbar 11 is arranged between the two first connecting pieces 3, and the driving device 1 includes a telescopic part 101, which is fixedly connected to the first connecting crossbar 11 through a hinged connecting piece 102. When the telescopic part 101 of the driving device 1 performs telescopic movement, it can drive the two first connecting pieces 3 to rotate relative to the base assembly 100, thereby indirectly driving the link assemblies 2 to work, realizing the function that a set of driving devices 1 drives two groups of link assemblies 2 to drive the leg support assembly 300 and the backrest assembly 200 to rotate cooperatively; as shown in Figure 9 、 Figure 10 a second connecting crossbar 13 is arranged between the two link assemblies 2. As a preferred example, the second connecting crossbar 13 is arranged on the two fourth connecting rods 204 inside the base assembly 100. When the telescopic part 101 of the driving device 1 performs telescopic movement, it can directly drive the link assemblies 2 to work, realizing the function that a set of driving devices 1 drives two groups of link assemblies 2 to drive the leg support assembly 300 and the backrest assembly 200 to rotate cooperatively.

[0061] The application discloses two modes of simultaneously driving two groups of connecting rod assemblies 2 by a single driving device 1, which significantly reduces the difficulty of power distribution and the number of parts in the system, and makes the overall structure more compact and easier to maintain.

[0062] As a preferred example of the application, the driving device 1 is fixed in the mounting cavity 5 of the base assembly 100, the telescopic part 101 of the driving device 1 is arranged in an inclined upward manner along the telescopic direction, when the driving device 1 drives the connecting rod assembly 2 to rotate the backrest assembly 200 and the leg support assembly 300, the leg support assembly 300 can be switched between the vertical state and the horizontal state, and the backrest assembly 200 can be switched between the vertical state and the inclined state.

As an example of the application, when the leg support assembly 300 is rotated to the horizontal state, the backrest assembly 200 is rotated to the inclined or horizontal lying state.
