Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a hand controller assembly and a massage chair. Background Technology

[0002] With the improvement of people's living standards and the enhancement of health awareness, massage chairs have been widely used in homes, offices, and various leisure venues, becoming a common device for relieving fatigue and relaxing the mind and body. As the core component for human-computer interaction between the user and the massage chair, the ease of design and user experience of the hand controller on the massage chair are of paramount importance.

[0003] Currently, the main ways to place the hand controllers on mainstream massage chairs on the market are as follows: Fixed storage slot type: A special groove is set on the inside or outside of the massage chair armrest for storing the hand controller. Although this method can fix the hand controller, the user needs to deliberately remove it before use and accurately align it back into the slot after use, which is a cumbersome operation.

[0004] Cable-suspended type: The hand controller is directly connected to the main body of the massage chair via a cable, usually suspended on one side of the armrest. While this method prevents the hand controller from being lost, the suspended cable looks messy, affecting the overall aesthetics of the massage chair. Furthermore, the swaying cable and hand controller may collide with the user's body during massage, causing unnecessary interference and posing a certain safety hazard.

[0005] Embedded design: The hand controller is completely embedded inside the armrest, requiring it to be popped out or removed for use. While this design maintains the clean appearance of the massage chair, the complex mechanical structure increases manufacturing costs and failure rates. Furthermore, the removal and insertion operation is not straightforward or convenient.

[0006] In summary, existing hand controller placement solutions generally suffer from problems such as "easy loss, inconvenient return to the correct location, unsightly appearance, and high cost".

[0007] Therefore, this application provides a new hand controller component and a massage chair to address the above-mentioned problems. Utility Model Content

[0008] The purpose of this utility model is to provide a hand controller assembly to at least alleviate the technical problems of easy loss, inconvenient return, unsightly appearance, and high cost that are common in the existing hand controller placement schemes in massage chairs.

[0009] The purpose of this utility model is also to provide a massage chair to further alleviate the technical problems of easy loss, inconvenience in returning to the original position, impact on aesthetics and high cost that are common in the existing massage chair hand controller placement schemes.

[0010] Based on the aforementioned first objective, this utility model provides a hand controller assembly, which includes a suspension base and a hand controller suspended above the suspension base. The hand controller is provided with a first magnetic unit, and the suspension base is provided with a second magnetic unit. The side of the first magnetic unit near the suspension base is a first magnetic surface, and the side of the second magnetic unit near the hand controller is a second magnetic surface. In this configuration, one of the first magnetic surfaces and the second magnetic surface has either a first magnetic pole or a second magnetic pole, while the other magnetic surface has both a first magnetic pole and a second magnetic pole. This allows the repulsive force generated by the same magnetic poles and the attractive force generated by opposite magnetic poles between the first and second magnetic surfaces to counteract the gravity of the hand controller. As a result, the hand controller is in force balance and can levitate above the suspension base. The first magnetic pole and the second magnetic pole have opposite polarities.

[0011] Furthermore, the first magnetic unit includes a protective sleeve and a first magnet disposed inside the protective sleeve. The side of the first magnet closest to the suspension seat is the first magnetic surface, and the polarity of the first magnetic surface is either a first magnetic pole or a second magnetic pole.

[0012] Furthermore, the protective sleeve has an opening, through which the first magnet can be placed inside the protective sleeve.

[0013] Furthermore, the outer surface of the protective sleeve is provided with buffer ribs, and multiple buffer ribs are provided, arranged in an array on the outer surface of the protective sleeve.

[0014] Furthermore, the hand controller includes a housing, which includes a lower housing and an upper cover disposed on the upper end of the lower housing. The lower housing and the upper cover are detachably connected to form an inner cavity, and the first magnetic unit is disposed in the inner cavity.

[0015] Furthermore, the second magnetic unit includes a fixing box and a magnetic assembly disposed on the fixing box, wherein the side of the magnetic assembly closest to the hand controller is the second magnetic surface; The magnetic assembly includes a first magnetic block and a second magnetic block, wherein the first magnetic block causes the second magnetic surface to have a first magnetic pole, and the second magnetic block causes the second magnetic surface to have a second magnetic pole.

[0016] Furthermore, multiple first magnetic blocks are provided, and multiple first magnetic blocks are arranged sequentially on the fixed box along a first direction to form a first magnetic group; multiple second magnetic blocks are provided, and multiple second magnetic blocks are arranged sequentially on the fixed box along a second direction to form a second magnetic group. Multiple first magnetic groups and multiple second magnetic groups are arranged sequentially and spaced apart on the fixed box along a second direction to form the magnetic group, wherein the first direction is perpendicular to the second direction.

[0017] Furthermore, the suspension seat includes a seat body, and the second magnetic unit is disposed on the seat body and detachably connected to the seat body.

[0018] Furthermore, the first magnet, the first magnetic block, and the second magnetic block are all neodymium iron boron magnets.

[0019] By adopting the above technical solution, the hand controller assembly of this utility model has at least the following beneficial effects: In use, the hand controller assembly of this embodiment has its suspension seat mounted on the massage chair body, with the hand controller suspended above the suspension seat. Optionally, the first magnetic surface has a first magnetic pole, and the second magnetic surface has both a first and a second magnetic pole. Therefore, a repulsive force is generated between the first magnetic surface and the first magnetic pole of the second magnetic surface, and an attractive force is generated between the first magnetic surface and the second magnetic pole of the second magnetic surface. These repulsive and attractive forces can counteract the weight of the hand controller, balancing its force. Alternatively, the first magnetic surface has a second magnetic pole, and the second magnetic surface has both a first and a second magnetic pole. Therefore, an attractive force is generated between the first magnetic surface and the first magnetic pole of the second magnetic surface, and a repulsive force is generated between the first magnetic surface and the second magnetic pole of the second magnetic surface. These repulsive and attractive forces can counteract the weight of the hand controller, balancing its force. Alternatively, the first magnetic surface has a first magnetic pole and a second magnetic pole, and the polarity of the second magnetic surface is the first magnetic pole. Therefore, a repulsive force is generated between the second magnetic surface and the first magnetic pole of the first magnetic surface, and an attractive force is generated between the second magnetic surface and the second magnetic pole of the first magnetic surface. The above repulsive and attractive forces can counteract the gravity of the controller, so that the controller is in force balance.

[0020] In summary, the repulsive force generated by like-polarity magnetic poles and the attractive force generated by unlike-polarity magnetic poles can counteract the gravity of the hand controller. In other words, the forces acting on the hand controller include upward repulsive force, downward attractive force, and gravity. The sum of the attractive force and gravity equals the repulsive force, balancing the forces on the hand controller. Therefore, without external interference, the hand controller can always remain stably suspended above the suspension base. Since the hand controller remains suspended above the suspension base, users can easily remove and place it above the suspension base; it will automatically return to its original position without requiring precise alignment. This simple and convenient operation allows for quick and easy removal and return. Furthermore, the wireless connection between the hand controller and the suspension base does not affect the aesthetics of the massage chair or interfere with the massage process. Moreover, the hand controller component in this embodiment has a simple structure and low cost, improving the reliability and safety of the massage chair and fundamentally enhancing user convenience and overall user experience.

[0021] Based on the second objective mentioned above, this utility model provides a massage chair, which includes a massage chair body and the aforementioned hand controller assembly. The suspension seat of the hand controller assembly is connected to the massage chair body, and the hand controller of the hand controller assembly is suspended above the suspension seat.

[0022] By adopting the above technical solution, the massage chair of this utility model has at least the following beneficial effects: By incorporating the aforementioned hand controller assembly into the massage chair, the massage chair thus possesses all the advantages of the aforementioned hand controller assembly, which will not be elaborated upon here.

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Example 1 Please see Figure 2 and combined Figure 4 and Figure 9 This embodiment provides a hand controller assembly, which includes a suspension base 1 and a hand controller 2 suspended above the suspension base 1. The hand controller 2 is provided with a first magnetic unit 21, and the suspension base 1 is provided with a second magnetic unit 11. The side of the first magnetic unit 21 near the suspension base 1 is a first magnetic surface, and the side of the second magnetic unit 11 near the hand controller 2 is a second magnetic surface. Among the first magnetic surface and the second magnetic surface, one magnetic surface has a first magnetic pole or a second magnetic pole, and the other magnetic surface has both a first magnetic pole and a second magnetic pole. This is so that the repulsive force generated by the like magnetic poles and the attractive force generated by the opposite magnetic poles between the first magnetic surface and the second magnetic surface can counteract the gravity of the hand controller 2, thereby balancing the forces and allowing the hand controller 2 to suspend above the suspension base 1. The first magnetic pole and the second magnetic pole have opposite polarities.

[0030] In this embodiment, the hand controller assembly is used by mounting the suspension seat 1 on the massage chair body 3, with the hand controller 2 suspended above the suspension seat 1. Optionally, the first magnetic surface has a first magnetic pole, and the second magnetic surface has both a first and a second magnetic pole. Therefore, a repulsive force is generated between the first magnetic surface and the first magnetic pole of the second magnetic surface, and an attractive force is generated between the first magnetic surface and the second magnetic pole of the second magnetic surface. These repulsive and attractive forces can counteract the weight of the hand controller 2, balancing the force on the hand controller 2. Alternatively, the first magnetic surface has a second magnetic pole, and the second magnetic surface has both a first and a second magnetic pole. Therefore, an attractive force is generated between the first magnetic surface and the first magnetic pole of the second magnetic surface, and a repulsive force is generated between the first magnetic surface and the second magnetic pole of the second magnetic surface. These repulsive and attractive forces can counteract the weight of the hand controller 2, balancing the force on the hand controller 2. Alternatively, the first magnetic surface has a first magnetic pole and a second magnetic pole, and the polarity of the second magnetic surface is the first magnetic pole. Therefore, a repulsive force is generated between the second magnetic surface and the first magnetic pole of the first magnetic surface, and an attractive force is generated between the second magnetic surface and the second magnetic pole of the first magnetic surface. The above repulsive and attractive forces can counteract the gravity of the hand controller 2, so that the hand controller 2 is in force balance.

[0031] In summary, since the repulsive force generated by the same polarity magnetic poles and the attractive force generated by the opposite polarity magnetic poles can counteract the gravity of the hand controller 2, that is, the forces on the hand controller 2 include the upward repulsive force, the downward attractive force, and gravity. The sum of the attractive force and gravity equals the repulsive force, so that the hand controller 2 is in force balance. Thus, without external interference, the hand controller 2 can always be stably suspended above the suspension seat 1. Since the hand controller 2 can always hover above the suspension seat 1, the user only needs to place the hand controller 2 above the suspension seat 1 to pick it up and put it back in place. The hand controller 2 will automatically return to its original position, allowing for easy and quick picking up, putting down, and returning without the need for precise alignment by the user. The operation is simple and convenient. In addition, since the hand controller 2 and the suspension seat 1 are connected wirelessly, it will not affect the aesthetics of the massage chair, nor will it interfere with or affect the massage process. Furthermore, the hand controller component in this embodiment has a simple structure and low cost, which improves the reliability and safety of the massage chair and fundamentally enhances the convenience of user operation and the overall user experience.

[0032] Preferably, please refer to Figure 8 In this embodiment, the first magnetic unit 21 includes a protective sleeve 211 and a first magnet 214 disposed inside the protective sleeve 211. The side of the first magnet 214 near the suspension seat 1 is a first magnetic surface, and the polarity of the first magnetic surface is either a first magnetic pole or a second magnetic pole.

[0033] Specifically, the first magnet 214 has two surfaces arranged opposite to each other with opposite polarities. The side of the first magnet 214 that is close to the suspension seat 1 is the first magnetic surface. The polarity of the first magnetic surface can be either the first magnetic pole or the second magnetic pole, both of which can suspend the hand controller 2 above the suspension seat 1.

[0034] Optionally, the protective sleeve 211 is a soft rubber sleeve that can protect the first magnet 214.

[0035] Preferably, please refer to Figure 6 and Figure 7 In this embodiment, the protective sleeve 211 is provided with an opening 212, and the first magnet 214 can be placed inside the protective sleeve 211 through the opening 212.

[0036] The opening 212 facilitates the insertion of the first magnet 214 into the protective sleeve 211 and the removal of the first magnet 214 from the protective sleeve 211.

[0037] Preferably, please refer to Figure 5 and Figure 6 In this embodiment, the outer surface of the protective sleeve 211 is provided with buffer ribs 213, and multiple buffer ribs 213 are provided, and multiple buffer ribs 213 are arranged in an array on the outer surface of the protective sleeve 211.

[0038] The buffer rib 213 plays a role in buffering and shock absorption, has energy absorption properties, and improves its out-of-plane compressive strength and the protective strength against the first magnet 214.

[0039] Preferably, please refer to Figure 5 A buffer rib 213 is formed into a hexagon. Optionally, multiple buffer ribs 213 are arranged in a multi-row, multi-column array or in a circular array on the outer surface of the protective sleeve 211. This arrangement further improves the protective strength against the first magnet 214.

[0040] Preferably, please refer to Figure 3 and Figure 4 In this embodiment, the hand controller 2 includes a housing, which includes a lower housing 22 and an upper cover 23 disposed on the upper end of the lower housing 22. The lower housing 22 and the upper cover 23 are detachably connected to form an inner cavity, and the first magnetic unit 21 is disposed in the inner cavity.

[0041] Optionally, the lower housing 22 and the upper cover 23 can be connected by snap-fit, fastening, or threaded connection, which improves the convenience of connecting and disassembling the lower housing 22 and the upper cover 23.

[0042] For example, the lower housing 22 is provided with a slot, and the first magnetic unit 21 is engaged in the slot to limit the first magnetic unit 21 and prevent the first magnetic unit 21 from shifting in the inner cavity.

[0043] With this setup, the first magnet 214 is inserted into the protective sleeve 211 through the opening 212, the protective sleeve 211 is then inserted into the slot of the lower housing 22, and finally the upper cover 23 is placed on the lower housing 22 to connect the two and complete the assembly of the hand controller 2.

[0044] Preferably, please refer to Figure 10 In this embodiment, the second magnetic unit 11 includes a fixing box 111 and a magnetic assembly disposed on the fixing box 111. The side of the magnetic assembly near the hand controller 2 is the second magnetic surface. The magnetic assembly includes a first magnetic block 113 and a second magnetic block 114. The first magnetic block 113 gives the second magnetic surface a first magnetic pole, and the second magnetic block 114 gives the second magnetic surface a second magnetic pole.

[0045] For example, see Figure 10 In the figure, to distinguish the first magnetic block 113 from the second magnetic block 114, a fill line is marked on the first magnetic block 113. It should be noted that the first magnetic block 113 has two opposing surfaces with opposite polarities, wherein the polarity of the side of the first magnetic block 113 closest to the second magnetic surface is the first magnetic pole. The second magnetic block 114 also has two opposing surfaces with opposite polarities, wherein the polarity of the side of the second magnetic block 114 closest to the second magnetic surface is the second magnetic pole. This arrangement allows the second magnetic surface to simultaneously possess both the first and second magnetic poles.

[0046] Preferably, please refer to Figure 10 In this embodiment, multiple first magnetic blocks 113 are provided, and multiple first magnetic blocks 113 are arranged sequentially on the fixing box 111 along the first direction to form a first magnetic group. Multiple second magnetic blocks 114 are provided, and multiple second magnetic blocks 114 are arranged sequentially on the fixing box 111 along the second direction to form a second magnetic group. Multiple first magnetic groups and multiple second magnetic groups are arranged sequentially and alternately on the fixing box 111 along the second direction to form a magnetic group, wherein the first direction is perpendicular to the second direction.

[0047] For example, the first direction is set along the length of the fixing box 111, and the second direction is set along the width of the fixing box 111. This arrangement makes the attraction and repulsion forces of the magnetic group on the second magnetic unit 11 on the first magnetic unit 21 alternate evenly, so that the hand controller 2 is subjected to uniform force and can be more stably suspended above the suspension seat 1.

[0048] Optionally, the shapes of the first magnetic block 113 and the second magnetic block 114 can be polygons such as triangles, quadrilaterals, pentagons or hexagons, or circles.

[0049] Preferably, please refer to Figure 10 In this embodiment, the suspension seat 1 includes a seat body 12, and a second magnetic unit 11 is disposed on the seat body 12 and is detachably connected to the seat body 12.

[0050] For example, the fixing box 111 of the second magnetic unit 11 is connected to the base 12 by means of snap-fit, fastening, or threaded connection. Preferably, in this embodiment, the base 12 is provided with a fixing groove 121, and the fixing groove 121 is provided with a plurality of first buckles 122 circumferentially. The base 12 is also provided with a first connecting hole 123, and the fixing box 111 is provided with a second connecting hole 112. The fixing box 111 of the second magnetic unit 11 can be placed in the fixing groove 121 and fastened to the base 12 by the first buckles 122. Then, the threaded connector is screwed through the first connecting hole 123 and screwed into the second connecting hole 112 to complete the fixing of the second magnetic unit 11.

[0051] Preferably, in this embodiment, the first magnet 214, the first magnetic block 113 and the second magnetic block 114 are all neodymium iron boron magnets.

[0052] It should be noted that neodymium iron boron magnets are tetragonal crystals formed by neodymium, iron, and boron (Nd2Fe14B), which have excellent magnetic properties and can provide stable magnetic force for the hand controller 2.

[0053] Example 2 Embodiment 2 provides a massage chair, which includes the hand controller assembly of Embodiment 1. The technical features of the hand controller assembly disclosed in Embodiment 1 are also applicable to this embodiment, and the technical features of the hand controller assembly disclosed in Embodiment 1 will not be described again. The implementation of the massage chair will be further described in detail below with reference to the accompanying drawings.

[0054] Please see Figure 1 and Figure 2 The massage chair provided in this embodiment includes a massage chair body 3 and the above-mentioned hand controller assembly. The suspension seat 1 of the hand controller assembly is connected to the massage chair body 3, and the hand controller 2 of the hand controller assembly is suspended above the suspension seat 1.

[0055] Optionally, the seat body 12 of the suspension seat 1 can be detachably connected to the massage chair body 3. For example, the seat body 12 is provided with a second buckle 124 and a third connecting hole. The seat body 12 can be fastened to the massage chair body 3 through the second buckle 124, and the threaded connector can be screwed onto the massage chair body 3 after passing through the third connecting hole to realize the connection between the suspension seat 1 and the massage chair body 3.

[0056] In the hand controller assembly, when the hand controller 2 and the suspension base 1 are close together with the same polarity, their magnetic fields are in the same direction, causing repulsion. When they are close together with opposite polarities, their magnetic fields are complementary, forming a closed loop and generating attraction. Therefore, a first magnet 214 formed by a neodymium iron boron magnet with an N or S pole is placed in the hand controller 2. Several first magnetic blocks 113 and second magnetic blocks 114 formed by hexagonal neodymium iron boron magnets are placed on the fixing box 111 in the suspension base 1 of the hand controller. The magnetic poles of the first magnetic blocks 113 and the second magnetic blocks 114 are arranged in an array, for example... Figure 10 In this design, a first magnetic block 113 with filler lines and a second magnetic block 114 without filler lines represent an N-pole magnetic block and an S-pole magnetic block, respectively, or an S-pole magnetic block and an N-pole magnetic block, respectively. This allows the first magnetic block 113 with filler lines to represent magnetic blocks of the same pole, and the second magnetic block 114 without filler lines to represent magnetic blocks of the same pole, while also allowing the first magnetic block 113 with filler lines and the second magnetic block 114 without filler lines to represent magnetic blocks of opposite poles. Figure 10 The arrangement forms a stable complementary closed loop, which generates an attractive and repulsive magnetic field on the first magnet 214 that is close to it, thereby achieving a levitation effect on the hand controller 2 that is close to it.

[0057] In the massage chair, the hand controller 2 is suspended above the suspension seat 1, allowing for easy and quick retrieval and return to its original position without precise alignment. When not in use, the hand controller 2 can be stably stored in a fixed position, maintaining the cleanliness and premium feel of the massage chair. This also avoids the use of messy cables or complex mechanical structures, improving the reliability and safety of the massage chair and fundamentally enhancing the ease of operation and overall user experience. The hand controller 2 achieves "ready to use, easy to return to its original position, and stable storage," greatly improving the product's convenience, aesthetics, and user experience.

[0058] The massage chair of this embodiment has the advantages of the hand controller assembly of Embodiment 1, which has been described in detail in Embodiment 1 and will not be repeated here.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
