[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0057] The terms "first" and "second" in this disclosure are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0058] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0059] The present invention provides an actuator and a massage device incorporating the same. The massage device is a type of massage equipment used to provide physiological massage to various organs, helping to relieve stress, promote blood circulation, and alleviate fatigue. Depending on the massage effect and massage needs, the massage device can be categorized into cervical massage devices, lumbar massage devices, wristband massage devices, massage cushions, and eye massage devices to meet various massage needs. The massage device provided by the present invention utilizes the actuator to achieve physiological massage.

[0060] See also Figure 1 、 Figure 2 The actuating device 1 includes at least one actuating assembly 10 , that is, the actuating device 1 may include only one actuating assembly 10 , or may include multiple (that is, greater than or equal to two) actuating assemblies 10 .

[0061] For a solution including a plurality of actuating assemblies 10 , the plurality of actuating assemblies 10 may be stacked, wherein the actuating direction of each actuating assembly 10 is consistent, so as to enhance the actuating effect.

[0062] Optionally, each actuator assembly 10 can be connected to a different power source and configured to be independently controlled, wherein the electromotive forces of the multiple different power sources can be different or the same.

[0063] In this way, multiple actuating assemblies 10 are configured to be independently controlled, and the required number of actuating assemblies 10 can be controlled to work according to actuation needs, so as to provide massage effects of different intensities, thereby improving the flexibility and applicability of the actuating assemblies 10 and the actuating device 1.

[0064] For example, one of the actuating components 10 can be controlled to actuate individually, while the other actuating components 10 do not work, and the actuating effect of the actuating device 1 is minimized; or all the actuating components 10 can be controlled to actuate together, and at this time the actuating effect of the actuating device 1 is maximized.

[0065] like Figure 1 In the figure, the actuating device 1 includes three actuating components 10, and the three actuating components 10 are respectively connected to three different power sources ε1, ε2, and ε3.

[0066] In other embodiments, the actuating device 1 includes two, four, five or more actuating assemblies 10 .

[0067] It should be pointed out that the power supply claimed in this application may refer to a power supply that has / can generate electrical energy, or an electrical connector / electrical connection portion for electrically connecting to an external power supply.

[0068] Optionally, an insulating layer 11 may be provided between each two adjacent actuating components 10 to prevent circuit contact between the actuating components 10 .

[0069] Optionally, the insulating layer 11 may be a flexible layer, such as made of a flexible insulating material, such as a silicone sheet, or the insulating layer 11 may be a plating layer or a coating, so as to improve the flexibility of the actuating assembly 10 and the actuating device.

[0070] The actuator 1 can generate actuation kinetic energy, converting electrical energy into kinetic energy for external actuation. The actuator assembly 10 is the factor that enables the actuator 1 to generate actuation kinetic energy. For details about the actuator assembly 10, please refer to the following description of the actuator assembly 10.

[0071] Continue reading Figure 2 The actuator assembly 10 includes a first electrodeformable layer 100, a first electrode 110, and a second electrode 120, wherein the first electrodeformable layer 100 is used to generate deformation when an electric field is applied, the first electrode 110 is arranged on one side of the first electrodeformable layer 100, and the second electrode 120 is arranged on the other side of the first electrodeformable layer 100, and the second electrode 120 is used to form a first electric field with the first electrode 110.

[0072] Specifically, the first electrodeformable layer 100 has two sides in its thickness direction, the first electrode 110 is connected to one side thereof, and the second electrode 120 is connected to the other side thereof.

[0073] The first electrodeformable layer 100 can produce an electrostrictive effect under the action of the electric field formed by the first electrode 110 and the second electrode 120. Specifically, when an electric field is applied to the first electrodeformable layer 100, the first electrodeformable layer 100 can be deformed. The deformation here refers to the change in the physical form of the first electrodeformable layer 100 when the electric field is applied, compared to the physical form when no electric field is applied. For example, the first electrodeformable layer 100 contracts or expands in the thickness direction. The deformation here also refers to the bending deformation of the first electrodeformable layer 100 due to the different intensities of the electric field applied to different parts of the first electrodeformable layer 100 when the area of the first electrodeformable layer 100 is large. It can be understood that the bending deformation is caused by the different deformation amounts in the thickness direction of different parts of the first electrodeformable layer 100.

[0074] The deformation of the first electrodeformable layer 100 provides an actuation effect for the actuator assembly 10. Furthermore, continuously applying a preset electric field enables the actuator device 1 to achieve a continuous actuation effect. If the electric field acts on the electrodeformable layer 100 at a certain frequency, the electrodeformable layer 100 will generate mechanical vibrations at the same frequency, thereby causing the actuator assembly 10 to vibrate.

[0075] Furthermore, the first electrodeformable layer 100 deforms under an electric field. After the electric field is removed, the first electrodeformable layer 100 returns to, or partially returns to, its initial shape. The first electrode 110 and the second electrode 120 are electrically connected and are each connected to a power source ε. A first electric field is formed between the first electrode 110 and the second electrode 120. This first electric field provides deformation conditions for the first electrodeformable layer 100, enabling the first electrodeformable layer 100 to undergo the aforementioned deformation under the first electric field. The deformation of the first electrodeformable layer 100 is the key to generating the actuation kinetic energy of the actuation assembly 10, enabling the actuation assembly 10 to generate actuation in the deformation direction of the first electrodeformable layer 100.

[0076] Specifically, the deformation of the first electrodeformable layer 100 under an electric field is elastic deformation, which can be divided into two forms: "the first electrodeformable layer 100 contracts when an electric field is applied and expands when no electric field is applied" and "the first electrodeformable layer 100 expands when an electric field is applied and contracts when no electric field is applied." In the following embodiments of the invention, "the first electrodeformable layer 100 contracts when an electric field is applied and expands when no electric field is applied" is mainly used as an example for explanation. In this solution, optionally, when it is applied to a massage device, a capacitor can be added to the circuit that forms the electric field to maintain the circuit in a normally closed state, or the first electrodeformable layer 100 can be maintained in a normally expanded state.

[0077] It can be understood that the first electrode is connected to one side of the first electrodeformable layer 100 and can move with the deformation of the first electrodeformable layer 100; the second electrode is connected to the other side of the first electrodeformable layer 100 and can also move with the deformation of the first electrodeformable layer 100.

[0078] Optionally, the first electrode may be a flexible layer configured to deform in response to bending of the first electrodeformable layer; and / or the second electrode may be a flexible layer configured to deform in response to bending of the first electrodeformable layer. This can improve the overall flexibility of the actuator assembly 10 and the actuator device.

[0079] Furthermore, if Figure 1-4 As shown, the second electrode 120 is provided with a first avoidance hole 121, which is used to allow part of the first electrodeformable layer 121 to enter when the first electrodeformable layer contracts. It should be noted that the term "contracted" in this application refers to a state, not an action.

[0080] In this way, when the first electrodeformable layer 100 is deformed, part of the first electrodeformable layer 100 can move into the first avoidance hole 121, thereby increasing the deformation degree of the first electrodeformable layer 100, thereby increasing the actuation range of the actuating device 1 and improving the actuation effect.

[0081] The first avoidance hole 121 can be set as either a through hole or a non-through hole, and when it is a non-through hole, the first avoidance hole 121 is set on the side of the second electrode 120 facing the first electrodeformable layer 100. In this embodiment, the first avoidance hole 121 is a through hole.

[0082] Specifically, if Figure 3 As shown, when the first electrodeformable layer 100 contracts in its thickness direction under the influence of the first electric field, it can be partially squeezed into the first avoidance hole 121. This portion of the first electrodeformable layer 100 that enters the first avoidance hole 121 is the hole-extrusion portion 100n. In other words, the first avoidance hole 121 provides deformation space for the first electrodeformable layer 100. This allows the first electrodeformable layer 100 to deform more significantly, and the actuation range is also increased, compared to a case where the first avoidance hole 121 is not provided.

[0083] In some embodiments, when the first electrodeformable layer 100 is able to stretch in the thickness direction under the influence of the first electric field, when no electric field is applied, that is, when the first electrodeformable layer 100 is deformed, the first electrodeformable layer 100 also includes a "hole extrusion portion 100n" arranged in the first avoidance hole 121. Therefore, after the electric field is canceled and the first electrodeformable layer 100 contracts, an avoidance space is provided for the hole extrusion portion 100n; when the electric field is applied, due to the addition of the "hole extrusion portion 100n", the stretching amount of the first electrodeformable layer 100 in its thickness direction can be increased, thereby also improving the actuation effect.

[0084] Alternatively, as Figure 2-4 As shown, the first avoidance hole 121 includes a plurality of holes distributed at intervals, which not only helps to simplify the design of the first avoidance hole 121 but also provides more avoidance space.

[0085] The shape of the hole is not limited. Figure 4 The square hole can also be, but is not limited to, a combination of one or more of circular holes, elliptical holes, diamond holes and other parallelogram holes, waist-shaped holes, hexagonal holes and other polygonal holes, and extended holes that are bent at least once (such as U-shaped holes).

[0086] In order to facilitate production, the plurality of holes may be regularly distributed, such as in an array.

[0087] In some other embodiments, the first avoidance hole 121 may also be configured as a hole-shaped structure that extends continuously in a zigzag manner.

[0088] In some embodiments, in order to further improve the actuation range, the first electrode 110 may also be provided with an avoidance hole structure similar to the first avoidance hole 121 , which is used to allow a portion of the first electrodeformable layer to enter when the first electrodeformable layer contracts.

[0089] Furthermore, in some other embodiments, the first electrodeformable layer 100 may be configured as a porous structure.

[0090] In this way, when the first electrodeformable layer 100 is deformed by the first electric field, the porous structure in the first electrodeformable layer 100 can facilitate the deformation of the first electrodeformable layer 100 .

[0091] Optionally, the porous structure may be a honeycomb structure or a fiber structure, that is, fiber-like gaps exist inside the first electrodeformable layer 100 .

[0092] Specifically, the electrostrictive layer 100 is an elastic electrostrictive film that can produce an electrostrictive effect, generate elastic deformation under an electric field, and deform in the opposite direction when the electric field decreases or disappears.

[0093] The electrostrictive film is made of an electrostrictive material, such as PDMS (polydimethylsiloxane material) or PVC-gel (polyvinyl chloride gel material). That is, the electrostrictive film can be a PDMS film or a PVC-gel film.

[0094] PDMS and PVC-gel materials are lightweight, making them easier to carry than motor-powered massagers. Furthermore, these shape-shifting materials resemble biological muscle, so with appropriate control of the electric field and its variations, they can achieve massage effects similar to or equivalent to those of human hands.

[0095] In an optional embodiment of the present invention, the first electrodeformable layer 100 has a porous structure and is a PVC-gel film. The porous structure is filled with ionizable compounds (such as metal oxides, etc.). When an electric field is applied, the compound decomposes, and the cations and anions move toward the cathode and anode, respectively, thereby causing the first electrodeformable layer 100 to shrink. After the electric field disappears, the cations and anions recombine, causing the first electrodeformable layer 100 to expand.

[0096] Thus, by providing the first electrodeformable layer 100 with a porous structure, the combination or decomposition rate of anions and cations can be increased, thereby increasing the deformation speed of the first electrodeformable layer 100 and improving the actuation efficiency of the actuation component 10.

[0097] Optionally, the first electrode 110 and the second electrode 120 can be metal films, which can be gold, silver, copper films or alloy films thereof with good conductivity to increase the amount of charge that the first electrode 110 and the second electrode 120 can conduct, thereby increasing the utilization rate of electrical energy and reducing power consumption.

[0098] Optionally, the first electrode 110 and / or the second electrode 120 can be a coating formed on the side of the first electrodeformable layer 100 by a process such as electroplating or sputtering. This can not only enhance the flow of electrons between the first electrode 110 and / or the second electrode 120 and the first electrodeformable layer 100, increase the utilization rate of electrical energy, and reduce power consumption, but also enhance the bonding strength between the first electrode 110 and / or the second electrode 120 and the first electrodeformable layer 100, thereby preventing the electrode from falling off.

[0099] Furthermore, the first avoidance hole 121 is an etching structure, for example, an etching structure generated by chemical reaction or physical impact, and the etching method can be a corrosion method or a dry etching method.

[0100] In the present invention, the actuator 1 utilizes the deformation of the first electrodeformable layer 100 in the actuator assembly 10 under the action of a first electric field to achieve an actuation effect. Compared to motor actuation, this reduces motor noise and power consumption, thereby improving the energy efficiency of the actuator 1.

[0101] At the same time, a first avoidance hole 121 is provided on the second electrode 120 to provide a deformation space for the first electrodeformable layer 100 , thereby increasing the deformation amplitude of the first electrodeformable layer 100 and enlarging the actuation range of the actuating device 1 .

[0102] Moreover, it can realize bionic massage, with smooth and comfortable massage effect, without mechanical setbacks and other discomforts.

[0103] Moreover, it is driven by a flexible film and directly participates in massage. It has no other mechanical accessories such as rotating shafts and gears, and has a high degree of integration and fewer accessories.

[0104] Moreover, it can achieve stepless speed change and provide a strong sense of control.

[0105] Moreover, low-voltage driving can be achieved, and power consumption is lower, which can be beneficial to improving the endurance of the massage device.

[0106] See also Figure 5In the second embodiment of the actuator assembly, relative to the above embodiment, the actuator assembly 10 further includes a second electrodeformable layer 200 and a third electrode 210. The second electrodeformable layer 200 is arranged on a side of the first electrode 110 facing away from the first electrodeformable layer 100, and the third electrode 210 is arranged on a side of the second electrodeformable layer 200 facing away from the first electrode 110.

[0107] In this embodiment, the third electrode 210 can be electrically connected to the second electrode 120, and the first electrode 120, the second electrode 120, and the third electrode 210 can be connected to the power source ε. In this way, the third electrode 210 and the first electrode 110 are used to form a second electric field, while the first electrode 110 and the second electrode 120 also form a first electric field.

[0108] Similarly to the first electrodeformable layer 100, the second electrodeformable layer 200 will also deform under the influence of the second electric field. At the same time, the third electrode 210 can be provided with a second avoidance hole 211. The second avoidance hole 211 is used to allow a portion of the second electrodeformable layer 200 to enter when the second electrodeformable layer 200 contracts. In other words, the second avoidance hole 211 is used to provide deformation space for the second electrodeformable layer 200. The first electrodeformable layer 100 and the second electrodeformable layer 200 are respectively provided on either side of the first electrode 110. The two electrodeformable layers share the first electrode 110, achieving the effect of three electrodes controlling the two electrodeformable layers, simplifying the structure and reducing costs.

[0109] In this embodiment, the actuating assembly 10 includes two electrodeformable layers, and corresponding electrodes for providing deformation are provided on both sides of the two electrodeformable layers. Both electrodeformable layers can be deformed under an electric field. Compared with an actuating assembly that only uses one electrodeformable layer, the two electrodeformable layers can provide a larger actuation range and bring better actuation effect.

[0110] In a further embodiment of the actuating assembly based on this embodiment, an avoidance hole structure may be provided on the first electrode, and the avoidance hole structure is used to allow a portion of the first electrodeformable layer to enter when the first electrodeformable layer contracts, and / or to allow a portion of the second electrodeformable layer to enter when the second electrodeformable layer contracts, so as to further improve the actuation stroke.

[0111] In other embodiments of the actuating assembly, the common electrode of the two electrodeformable layers may also be the second electrode 120 .

[0112] Specifically, if Figure 6As shown, in the third embodiment of the actuator assembly 10, the actuator assembly 10 further includes a third electrodeformable layer 300 and a fourth electrode 310 on the basis of the second embodiment. The third electrodeformable layer 300 is arranged on the side of the second electrode 120 facing away from the first electrodeformable layer 100, and the fourth electrode 310 is arranged on the side of the third electrodeformable layer 300 facing away from the first electrodeformable layer 100.

[0113] When in use, the fourth electrode 310 is electrically connected to the first electrode 110, and the first electrode 120, the second electrode 120, and the fourth electrode 310 are electrically connected to the power supply ε. The first electrode 110 and the second electrode 120 form a first electric field, and the fourth electrode 310 and the second electrode 120 form a third electric field.

[0114] Similarly, the third electrodeformable layer 300 is deformed under the third electric field to provide an actuation effect.

[0115] In this embodiment, the first electrodeformable layer 100 and the third electrodeformable layer 300 share a second electrode 120. A first avoidance hole 121 is provided on the second electrode 120. First avoidance hole 121 can be a through hole, which provides deformation space for the first and second electrodeformable layers 100 and 100. Therefore, the second electrode 120 is not only used to form the first and third electric fields, but also to share the first avoidance hole 121, saving manufacturing costs.

The fifth electrode 410 is disposed on a side of the fourth electrodeformable layer 400 away from the first electrode 110 .

[0123] like Figure 8As shown, in the fifth embodiment of the actuator assembly, a fifth electrodeformable layer 500 and a sixth electrode 510 are additionally provided on the basis of the fourth embodiment of the actuator assembly, that is, the actuator assembly 10 further includes a fifth electrodeformable layer 500 and a sixth electrode 510, the fifth electrodeformable layer 500 is provided on the side of the fifth electrode 410 away from the first electrode 110, the sixth electrode 510 is provided on the side of the fifth electrodeformable layer 500 away from the first electrode 110, the sixth electrode 510 is provided on the side of the fifth electrodeformable layer 500 away from the first electrode 110, the sixth electrode 510 is used to electrically connect to the second electrode 120, and form a fifth electric field with the fifth electrode 410, and the sixth electrode 510 is provided with a third avoidance hole 511 for providing deformation space for the fifth electrodeformable layer 500.

[0124] During use, the first electrode 110, the second electrode 120, the third electrode 210, the fifth electrode 410, and the sixth electrode 510 are respectively connected to a power source ε. The second electrode 120 forms a first electric field with the first electrode 110, the third electrode 210 forms a second electric field 120 with the first electrode 110, the fifth electrode 410 forms a fourth electric field with the third electrode 210, and the sixth electrode 510 forms a fifth electric field with the fifth electrode 410. Different electrodeformable layers deform under the action of their corresponding electric fields.

[0125] like Figure 9 As shown, in the sixth embodiment of the actuator assembly, a sixth electrodeformable layer 600 and a seventh electrode 610 are additionally provided on the basis of the fifth embodiment of the actuator assembly, that is, the actuator assembly 10 further includes a sixth electrodeformable layer 600 and a seventh electrode 610. The sixth electrodeformable layer 600 is provided on the side of the second electrode 120 away from the first electrodeformable layer 100, and the seventh electrode 610 is provided on the side of the sixth electrodeformable layer 600 away from the second electrode 120. The seventh electrode 610 is electrically connected to the first electrode 110 and is used to form a sixth electric field with the second electrode 120.

[0126] During application, the first electrode 110, the second electrode 120, the third electrode 210, the fifth electrode 410, the sixth electrode 510, and the seventh electrode 610 are respectively connected to the power supply ε, the second electrode 120 and the first electrode 110 form a first electric field, the third electrode 210 and the first electrode 110 form a second electric field 120, the fifth electrode 410 and the third electrode 210 form a fourth electric field, the sixth electrode 510 and the fifth electrode 410 form a fifth electric field, and the seventh electrode 610 and the second electrode 120 form a sixth electric field. Different electrodeformable layers are deformed under the action of their corresponding electric fields.

[0127] like Figure 10As shown, in the seventh embodiment of the actuator assembly, a seventh electrodeformable layer 700 and an eighth electrode 710 are additionally provided on the basis of the fourth embodiment of the actuator assembly, that is, the actuator assembly 10 further includes a seventh electrodeformable layer 700 and an eighth electrode 710. The seventh electrodeformable layer 700 is provided on the side of the second electrode 120 away from the first electrodeformable layer 100, and the eighth electrode 710 is provided on the side of the seventh electrodeformable layer 700 away from the second electrode 120. The eighth electrode 710 is electrically connected to the first electrode 110 and is used to form a seventh electric field with the second electrode 120.

[0128] During application, the first electrode 110, the second electrode 120, the third electrode 210, the fifth electrode 410, and the eighth electrode 710 are respectively connected to the power supply ε, the second electrode 120 and the first electrode 110 form a first electric field, the third electrode 210 and the first electrode 110 form a second electric field 120, the fifth electrode 410 and the third electrode 210 form a fourth electric field, and the eighth electrode 710 and the second electrode 120 form a seventh electric field. Different electrodeformable layers are deformed under the action of their corresponding electric fields.

[0129] In this way, more electrodeformable layers and electrode layers can be added according to the actuation requirements in the above manner to increase the actuation range of the actuation component 10 and improve the actuation effect; and adjacent electrodeformable layers can share one electrode, which can simplify the structure and save costs.

[0130] Optionally, the above description of the embodiments of the present invention is merely a description of some exemplary embodiments and does not limit the number of electrodeformable layers and electrodes. Those skilled in the art may increase or decrease the number as needed.

[0131] It should be noted that, for a solution in which the actuating device 1 includes an actuating assembly 10 , a required number of electrodestructive layers and electrode layers may be provided as required to ensure a sufficient actuating effect.

[0132] Optionally, each of the electrodes may be provided with a hole structure to provide deformation space for the electrodeformable layer. Optionally, each electrodeformable layer may be a porous structure, such as a honeycomb structure or a fiber-like structure, to increase the actuation range of the actuating assembly 10 and improve actuation efficiency.

[0133] Please also refer to Figure 11A 、 Figure 11B and Figure 11CIn the eighth embodiment of the actuator assembly, the number of first electrodes 110 can be multiple. The multiple first electrodes 110 are arranged in an alternating pattern on one side of the first electrodeformable layer 100, and the second electrode 120 is arranged on the other side of the first electrodeformable layer 100. The second electrode 120 is provided with a first avoidance hole 121. Each first electrode 110 is used to form a first electric field with the second electrode 120. The multiple first electrodes 110 form an electrode layer, the second electrodes 120 form another electrode layer, and the multiple first electric fields form an electric field layer. In application, the multiple first electrodes 110 are connected in parallel to form a first electric field with each second electrode 120.

[0134] It can be understood that, in this embodiment, the first electrodeformable layer 100 generally has a larger area, such as being used to constitute the entire or half of the massage surface of the massage device.

[0135] In this way, multiple first electric fields can be formed, and by independently controlling each of the multiple first electric fields, a multi-point independent actuation effect can be achieved. When applied to a massage device, this can achieve a full-surface multi-point actuation massage effect. Alternatively, by controlling the electric field strengths of the multiple first electric fields, the first electrodeformable layer 100 can be bent and deformed to achieve a massage effect.

[0136] Of course, in other embodiments, the multi-point massage effect can also be achieved through other methods, which are described below with examples.

[0137] For example, please also see Figure 12A 、 Figure 12B and Figure 12C In the ninth embodiment of the actuator assembly, the number of second electrodes 120 can be multiple, with multiple second electrodes 120 spaced apart on one side of the first electrodeformable layer 100, and the first electrode 110 spaced apart on the other side of the first electrodeformable layer 100. Each second electrode 120 is provided with a first avoidance hole 121; and each second electrode 120 is used to form a first electric field with the first electrode 110. The first electrode 110 forms an electrode layer, the multiple second electrodes 120 form another electrode layer, and the multiple first electric fields form an electric field layer. During application, the multiple second electrodes 120 are connected in parallel to form a first electric field with the first electrode 120, respectively. At this time, due to the first avoidance hole 121 and the spacing gaps between the second electrodes 120, the first electrodeformable layer 100 will tend to deform in the direction of the second electrode 120.

[0138] For example, please also see Figure 13A 、 Figure 13B and Figure 13CIn the tenth embodiment of the actuator assembly, multiple first electrodes 110 and multiple second electrodes 120 can be provided. Multiple first electrodes 110 are arranged in a spaced arrangement on one side of the first electrostrictive layer 100, and multiple second electrodes 120 are arranged in a spaced arrangement on the other side of the first electrostrictive layer 100. The multiple first electrodes 110 and the multiple second electrodes 120 are arranged in a corresponding manner, and each first electrode is configured to form a first electric field with the corresponding second electrode 120. The second electrodes 120 are provided with first avoidance holes 211. The multiple first electrodes 110 form an electrode layer, the multiple second electrodes 120 form another electrode layer, and the multiple first electric fields form an electric field layer. In this case, the deformation space on both sides of the first electrostrictive film 100 is large, resulting in a wide deformation range.

[0139] It should be noted that, based on the eighth, ninth and tenth embodiments of the actuator assembly, more layers (such as a preset number of layers) of electrodestructive layers and electrode layers can be set as needed in the above manner to form more electric field layers, and the multiple electric fields of two adjacent electric field layers are set one by one.

[0140] Optionally, the actuating device may include a massage head, which is installed at the output end of the actuating assembly.

[0141] As can be seen from the above, the actuation direction that can be generated by the actuating device in the above embodiment is relatively single. Figure 14 In another embodiment of the actuator of the present invention, the actuator 1 may further include an output conversion member 12 , which can change the actuation output direction of the actuator 1 .

[0142] Specifically, the output conversion member 12 includes a conversion output portion 12a and a conversion connection portion 12b. Figure 14 As shown, the conversion connection part 12b is installed at the output end of the actuating assembly 10, and the conversion output part 12a is located on one side of the circumference of the actuating assembly 10. The conversion output part 12a has an output surface for setting corresponding to the massage part.

[0143] When the actuating assembly 10 is actuated, the output end of the actuating assembly 10 drives the conversion connection part 12b to move together, and the conversion connection part 12b drives the conversion output part 12a to move in the actuating direction of the actuating assembly 10. The side of the conversion output part 12a facing away from the actuating assembly 10 (i.e., the output surface) can act on the massaged area to achieve the change of the actuating output direction of the actuating device 1.

[0144] For example Figure 14In the embodiment, the output conversion member 12 is an "L"-shaped conversion plate, the conversion output portion 12a is the output plate, the conversion connection portion 12b is the connection plate, and the angle between the output plate and the connection plate can be selected to be greater than or equal to 30 degrees and less than or equal to 150 degrees, such as 30 degrees, 40 degrees, 45 degrees, 60 degrees, 75 degrees, 80 degrees, 90 degrees, 95 degrees, 120 degrees, 130 degrees, or 140 degrees.

[0145] In this embodiment, when the actuator 1 is applied to a massage device, the conversion output portion 12a can be set corresponding to the massage site to achieve massage along the extension direction of the surface of the massaged part.

[0146] It should be noted that, in this embodiment, when there is only one actuating assembly 10, the output conversion member 12 is installed at the output end of the actuating assembly 10; when there are multiple actuating assemblies 10, the output conversion member 12 can be installed at the output end of any actuating assembly, or it can be installed at the output end of a specific actuating assembly 10, such as the output end of the actuating assembly 10 located at the free end.

[0147] It can be understood that for an actuator 1 having an output conversion member 12, the actuator 1 can have two output ends. Specifically, when there is only one actuator assembly, the two output ends can be the conversion output portion 12a and the conversion connection portion 12b (i.e., the side of the conversion connection portion 12b facing away from the actuator assembly can act on the massage area). When there are multiple actuator assemblies, if the output conversion member 12 is mounted at the output end of the actuator assembly at the free end, the two output ends can also be the conversion output portion 12a and the conversion connection portion 12b. If the output conversion member 12 is mounted at the output end of the actuator assembly at the non-free end, the two output ends can also be the conversion output portion 12a and the output end of the actuator assembly at the free end. In this way, when the actuator 1 is applied to a massage device, the actuator 1 can be rotatably mounted on the body of the massage device to achieve multiple massage modes.

[0148] See also Figure 15 The present invention further provides a massage device, wherein the massage device 2 includes the actuating device 1 as described above. The specific structure of the actuating device 1 can be referred to the above embodiments and need not be described in detail here.

[0149] Specifically, the massage device further includes a device body, and the actuating device 1 is mounted on the device body.

[0150] Depending on the massage effect and massage needs, the massage device 2 can be divided into a cervical massage device, a waist massage device, a wristband massage device, a massage cushion, and an eye massage device, and can massage various parts of the body, such as the cervical spine, waist, wrists, ankles, back, buttocks, and eyes. Since the massage devices for different parts of the body have different massage effects, their specific forms also vary. For example, a wristband massage device is configured in a wristband shape, and a massage cushion is configured in a cushion shape. However, all use the actuator 1 as the actuator device, so the specific form and function of the massage device 2 are not limited.

[0151] like Figure 16 As shown, the massage device 2 may include a bracket 13 (i.e., the device body) and multiple actuators 1. In this embodiment, the bracket 13 is configured in a ring shape, adapted to be placed around the human cervical spine, wrist, or head. Multiple actuators 1 are mounted at intervals around the bracket 13. The multiple actuators 1 on the bracket 13 act as drivers, driving the massage device 2 to massage the massaged area. When the actuators 1 are placed around the human cervical spine, wrist, or head, they achieve a physiological massage effect without any noise or jerkiness.

[0152] Since the massage device 2 uses the actuating device 1 , the massage effect of the massage device 2 is smooth and noiseless, and the massage device 2 is more energy-efficient and lightweight.

[0153] The above massage device 2 is only an embodiment of a specific application of the actuating device 1, and does not limit the applicable scenarios of the actuating device 1. When other mechanical structures also require an actuating device, the actuating device 1 provided by the present invention can also be used as an actuating device.

[0154] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention's description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
