Description

Technical Field

[0001] The utility model relates to the technical field of driving, and particularly to a quick reset driving device, a control valve and an electrical equipment. Background Art

[0002] In the design of modern driving devices, motors have become the mainstream power sources due to their high efficiency, stability and wide application. However, with the development of technology, especially in special environments (such as narrow spaces or environments with strict noise restrictions), the demand for non-motor power sources is increasing. Therefore, electro-deformable elements such as shape memory alloys and electro-deformable polymers are introduced into the electrical field as the power sources of driving devices due to their unique physical properties.

[0003] However, the deformation principle of electro-deformable elements is all through electro-thermal effect, and then deformation is generated due to heat, and further driving force is generated. Based on this, it is determined that after the above electro-deformable elements are deformed, a certain amount of time is required to dissipate heat to restore their original shapes. This causes a problem of slow reset action when such driving devices need a reset action, which limits the application of such materials in driving devices that require quick reset.

Detailed implementation manners

[0041] In the driving device in the related art, when an electro-deformable element is used for driving, there is a problem of slow reset action.

[0042] In view of the above problems, the present utility model provides a quick reset driving device 10, a control valve, and an electrical device, which can drive a driven member to move forward and backward, and can solve the problem of slow reset action of the electro-deformable element driving device in the prior art.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0044] Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts fall within the scope of protection of the present invention.

[0045] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0046] In the description of the present invention, it should be noted that if terms such as "upper", "lower", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use, it is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0047] In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0048] It should be noted that the features in the embodiments of the present invention can be combined with each other without conflict.

[0049] The overall structure, working principle and technical effects achieved by the quick reset driving device 10 provided by the present invention are introduced in detail below through embodiments in combination with the drawings. Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic diagram of the driving device for linear driving provided in this embodiment, Figure 2 and

[0050] which is a schematic diagram of the driving device for rotary driving provided in this embodiment. The present invention provides a quick reset driving device 10, which is applied to a control valve, and specifically can be applied to the silent control valve of an intelligent pillow.

[0051] Specifically, one end of the first electro-deformable element 310 is connected to the first elastic element 510, and the other end is used to connect to the driven member. Moreover, the first electro-deformable element 310 is used to selectively connect to a power source; while one end of the second electro-deformable element 330 is connected to the first elastic element 510, and the other end is connected to the housing 100. Similarly, the second electro-deformable element 330 is also used to selectively connect to a power source.

[0052] It should be noted that the above-mentioned "selectively connect" specifically refers to "selectively energize". Applied to the actual scenario, taking the first electro-deformable element 310 as an example, when the first electro-deformable element 310 needs to deform, the first electro-deformable element 310 is connected to the power source; when the first electro-deformable element 310 needs to return to its original state, the first electro-deformable element 310 is disconnected from the power source. The second electro-deformable element 330 is similar, so it will not be elaborated here.

[0053] In addition, it should also be noted that the first electro-deformable element 310 and the second electro-deformable element 330 can be respectively connected to two power sources through a controller and selectively connected to the corresponding power sources; or they can be selectively connected to the same power source through a controller. And this power source can be a power device in the external environment, or it can be an internal power source included in the quick reset driving device 10. This application does not make a limitation.

[0054] Based on the above, when the first electro-deformable element 310 is energized and the second electro-deformable element 330 is de-energized, the first electro-deformable element 310 is heated and deformed, driving the driven member to move in the forward stroke, and at the same time deforming the second elastic element 530. During this process, the deformation of the first elastic element 510 is negligible. With the forward stroke movement of the driven member, the second elastic element 530 converts mechanical energy into elastic potential energy to achieve energy storage.

[0055] When the second electro-deformable element 330 is energized and the first electro-deformable element 310 is de-energized, due to slow heat dissipation, the de-energized first electro-deformable element 310 still maintains its deformed state and acts together with the pulling force of the first elastic element 510, making the second elastic element 530 still in the deformed state and difficult to release energy. And the energized second electro-deformable element 330 deforms the first elastic element 510, unloading a certain pulling force, so that the second elastic element 530 returns to its original state, converting elastic potential energy into mechanical energy to make the driven member move in the reverse stroke.

[0056] It should be noted that the forward stroke movement and the reverse stroke movement in the above description refer to the driven member moving along the preset direction and moving in the opposite direction of the preset direction, respectively. Additionally, it should also be noted that in the case of power-on heating, the electro-deformation element generated by the present application can contract or bend and become shorter, or can expand and become longer.

[0057] In the case where the driven member performs Figure 1 the linear motion shown, when the electro-deformation element contracts or bends and becomes shorter, the driven member moves linearly along the -x direction to perform the forward stroke movement, and moves linearly along the +x direction to perform the reverse stroke movement; while when the electro-deformation element expands and becomes longer, the driven member moves linearly along the +x direction to perform the forward stroke movement, and moves linearly along the -x direction to perform the reverse stroke movement.

[0058] In the case where the driven member performs Figure 2 the curvilinear motion shown, when the electro-deformation element contracts or bends and becomes shorter, the driven member rotates clockwise to perform the forward stroke movement, and rotates counterclockwise to perform the reverse stroke movement; while when the electro-deformation element expands and becomes longer, the driven member rotates counterclockwise to perform the forward stroke movement, and rotates clockwise to perform the reverse stroke movement.

[0059] It can be understood that the included angle between the first electro-deformation element 310 and the second electro-deformation element 330 in the embodiments provided by the present application is negligible. In the case where the electro-deformation element contracts or bends and becomes shorter as exemplified above, the elastic element is correspondingly stretched and elongated, and in the case where the electro-deformation element expands and becomes longer, the elastic element is correspondingly compressed and shortened, which will not be elaborated in the present application.

[0060] Therefore, based on the on-off setting of the first electro-deformation element 310 and the second electro-deformation element 330, on the one hand, it can enable the driven member to achieve rapid reset, so as to flexibly adapt to different motion requirements; on the other hand, on the basis of the stable operation and low noise of the rapid reset driving device 10, the structure of the rapid reset driving device 10 is simplified.

[0061] In the present application, the electro-deformation element can be set to different materials as needed. For example Figure 1 shown, both the first electro-deformation element 310 and the second electro-deformation element 330 are made of shape memory alloy. Specifically, the shape memory alloy can include nickel-titanium alloy or other alloys with thermal deformation; or, as Figure 3As shown, both the first electro-deformable element 310 and the second electro-deformable element 330 are made of electro-deformable polymers. Specifically, the electro-deformable polymers may include polyacrylic rubber and ion polymer gel; alternatively, in the embodiment where the electro-deformable element shown in Figure 4 is bent by heat, both the first electro-deformable element 310 and the second electro-deformable element 330 are made of bimetallic strips.

[0062] Similarly, the electro-deformable elements can also be set to different shapes according to needs. As shown in Figure 1 , both the first electro-deformable element 310 and the second electro-deformable element 330 are in a filamentous structure to facilitate rapid and consistent response; or, as shown in Figure 3 , both the first electro-deformable element 310 and the second electro-deformable element 330 are in a sheet structure to facilitate providing greater thrust or pulling force; or, as shown in Figure 5 , at least part of the first electro-deformable element 310 is in a helical structure, and at least part of the second electro-deformable element 330 is in a helical structure. Based on the above settings, on the one hand, a longer electro-deformable element can be stored in the smaller space of the housing 100 to achieve a greater stroke.

[0063] Applied to actual production, in the rapid reset driving device 10 shown in Figure 3 , when both the first electro-deformable element 310 and the second electro-deformable element 330 are made of electro-deformable polymers, they are both in a sheet structure; in the driving reset devices shown in Figure 1 and Figure 5 , when both the first electro-deformable element 310 and the second electro-deformable element 330 are made of shape memory alloy, they are both in a filamentous structure, or at least part of them is in a helical structure.

[0064] Please refer to Figure 6 and Figure 7 . To achieve a greater stroke, the driving device further includes at least a pair of pulley groups 900, and each pair of pulley groups 900 includes a first pulley 910 and a second pulley 930. It can be understood that the design of the pulley group 900 enables the electro-deformable element to be wound around rather than just extending in a straight line. This can maximize the actual working length of the electro-deformable element in a limited space, thereby achieving a greater deformation amount, and thus setting a greater stroke for the rapid reset driving device 10.

[0065] Specifically, the first electro-deformable element 310 is connected to the first elastic element 510 around all the first pulleys 910, and the second electro-deformable element 330 is connected to the first elastic element 510 around all the second pulleys 930. It can be understood that by guiding the first electro-deformable element 310 and the second electro-deformable element 330 through the first pulley 910 and the second pulley 930 respectively, the above-mentioned electro-deformable elements can travel along a longer path, enabling a larger stroke even in a smaller space.

[0066] When the first electro-deformable element 310 contracts, it generates a continuous pulling force along the path of the first pulley 910, enabling the driven member connected to its end to have a larger range of displacement. Similarly, when the first electro-deformable element 310 expands, through the guiding action of the first pulley 910, it can achieve a longer-distance reset. It can be understood that the working principle and beneficial effects of the second electro-deformable element 330 are similar to those of the first electro-deformable element 310, and will not be elaborated here.

[0067] It can be understood that the number of the pulley sets 900, the size of the first pulley 910, and the size of the second pulley 930 can all be set according to actual needs to meet different environmental and design requirements, which are not limited in this embodiment. Additionally, considering the insulation and high-temperature resistance of ceramics, both the first pulley 910 and the second pulley 930 are made of ceramic materials; considering the space utilization rate of the housing 100, the first pulley 910 and the second pulley 930 are coaxially arranged.

[0068] To facilitate the realization of different movements of the driven member relative to the housing 100, the quick reset driving device 10 further includes a connecting member 700. The connecting member 700 is rotatably or slidably connected to the housing 100, and the first electro-deformable element 310 is connected to the driven member through the connecting member 700. The second elastic element 530 is disposed between the connecting member 700 and the housing 100.

[0069] It can be understood that based on the setting of the connecting member 700 being rotatably connected to the housing 100, the connecting member 700 can rotate relative to the housing 100 with the connection point as the fulcrum, thereby driving the driven member to perform a curvilinear motion; while based on the setting of the connecting member 700 being slidably connected to the housing 100, the connecting member 700 can extend into or out of the housing 100 along a preset direction, thereby driving the driven member to perform a linear motion.

[0070] In addition, it should be noted that in the embodiment without the connecting member 700, the driven member can be directly slidably or rotatably connected to the housing 100 to facilitate corresponding linear or curvilinear motions. And the connecting member 700 in the drawings of this application is regarded as the driven member in the external environment to better understand the structural features of this application.

[0071] In Figure 8 and Figure 9 In the illustrated embodiment, the second elastic element 530 is a valve diaphragm 531, which plays a role of storing and releasing energy in the quick reset driving device 10 and helps to drive the driven member through the deformation and recovery process; the connecting member 700 is a valve stem for transmitting motion and force to the valve diaphragm 531. Optionally, the quick reset driving device 10 may further include a fixed seat connected to the housing 100, and the valve diaphragm 531 is fixedly connected to the housing 100 through the fixed seat.

[0072] Please refer to again Figure 1 , in some embodiments, both the first elastic element 510 and the second elastic element 530 are arranged as spring structures. Moreover, the spring constant of the first elastic element 510 is greater than that of the second elastic element 530. It should be noted that according to the elastic force calculation formula of the spring: F = -kx (where: k is the spring constant and x is the deformation amount), when the first electro-deformable element 310 is energized and contracts, since the first electro-deformable element 310 is located between the first elastic element 510 and the second elastic element 530, the first elastic element 510 and the second elastic element 530 are subjected to the same tensile force.

[0073] Therefore, only when the spring constant of the first elastic element 510 is greater than that of the second elastic element 530, the deformation amount of the first elastic element 510 is smaller and the deformation amount of the second elastic element 530 is larger, and the driven member can effectively perform the forward stroke movement. In addition, it should also be noted that in this embodiment, the second elastic element 530 is sleeved on the driven member.

[0074] Please refer to Figure 10 , in other embodiments, the first elastic element 510 and the second elastic element 530 are made of elastic materials, and specifically may be made of rubber or silica gel. Moreover, the elastic coefficient of the first elastic element 510 is greater than that of the second elastic element 530. It should be noted that according to Hooke's law expressed as F = -k·x or ΔF = -k·Δx (where k is a constant, the stiffness coefficient of the object), when the first electro-deformable element 310 is energized and contracts, since the first electro-deformable element 310 is located between the first elastic element 510 and the second elastic element 530, the first elastic element 510 and the second elastic element 530 are subjected to the same tensile force.

[0075] Therefore, similar to the above, only when the elastic coefficient of the first elastic element 510 is greater than that of the second elastic element 530, the deformation of the first elastic element 510 is smaller and the deformation of the second elastic element 530 is larger, and the driven member can effectively perform the forward stroke movement. In addition, it should be noted that when the elastic material is rubber, k refers to the elastic coefficient of rubber; when the elastic material is silica gel, k refers to the elastic coefficient of silica gel.

[0076] Based on the above settings, that is to say, when the first electro-deformable element 310 is energized and the second electro-deformable element 330 is de-energized, the deformation of the first elastic element 510 is smaller than that of the second elastic element 530 to ensure that the driven member can effectively perform the forward stroke movement. Therefore, in other embodiments, one of the first elastic element 510 and the second elastic element 530 can also be set as a spring structure, and the other is made of an elastic material to ensure the above deformation conditions.

[0077] Take Figure 8 the embodiment shown as an example, the working process and working principle of the quick reset drive provided by the present application are as follows:

[0078] When the first electro-deformable element 310 is energized and the second electro-deformable element 330 is de-energized, the first electro-deformable element 310 is thermally deformed, driving the connecting member 700 and the driven member to perform a forward stroke movement along the x-direction, and at the same time deforming the valve film 531. During this process, with the forward stroke movement of the driven member, the valve film 531 converts mechanical energy into elastic potential energy to achieve energy storage.

[0079] When the second electro-deformable element 330 is energized and the first electro-deformable element 310 is de-energized, due to slow heat dissipation, the first electro-deformable element 310 after power-off still maintains the deformed state, and together with the pulling force of the first elastic element 510, the valve film 531 also remains in the deformed state and is difficult to release energy. The energized second electro-deformable element 330 deforms the first elastic element 510 to unload a certain pulling force, so that the valve film 531 rebounds, converting elastic potential energy into mechanical energy, so that the driven member and the connecting member 700 perform a reverse stroke movement along the x+ direction.

[0080] In summary, the present application provides a quick reset driving device 10, which includes a housing 100, a first electro-deformable element 310, a second electro-deformable element 330, a first elastic element 510, and a second elastic element 530. When the first electro-deformable element 310 is powered on and the second electro-deformable element 330 is powered off, the first electro-deformable element 310 deforms due to heat, driving the driven member to move in the forward stroke, and at the same time deforming the second elastic element 530. During this process, as the driven member moves in the forward stroke, the second elastic element 530 converts mechanical energy into elastic potential energy to achieve energy storage. When the second electro-deformable element 330 is powered on and the first electro-deformable element 310 is powered off, due to slow heat dissipation, the first electro-deformable element 310 still maintains its deformed state after power-off, and together with the pulling force of the first elastic element 510, the second elastic element 530 also remains in a deformed state and is difficult to release energy. The powered-on second electro-deformable element 330 deforms the first elastic element 510, unloading a certain pulling force, so that the second elastic element 530 returns to its original state, converting elastic potential energy into mechanical energy to enable the driven member to move in the reverse stroke. Based on the on-off settings of the first electro-deformable element 310 and the second electro-deformable element 330, the driven member can achieve quick reset, thus flexibly adapting to different motion requirements.

[0081] In addition, the present application also provides a control valve, which includes the quick reset driving device 10 in the foregoing embodiment. Therefore, it can also switch the working states of the first electro-deformable element 310, the second electro-deformable element 330, the first elastic element 510, and the second elastic element 530 by the on-off of the first electro-deformable element 310 and the second electro-deformable element 330, improve the reaction speed of the driven member, enable it to achieve quick response and quick reset, and thus flexibly adapt to different motion requirements. Details are not described herein again in the present application.

[0082] In addition, the present application also provides an electrical device, which includes the quick reset driving device 10 or the electrical device in the foregoing embodiment. Therefore, it can also switch the working states of the first electro-deformable element 310, the second electro-deformable element 330, the first elastic element 510, and the second elastic element 530 by the on-off of the first electro-deformable element 310 and the second electro-deformable element 330, improve the reaction speed of the driven member, enable it to achieve quick response and quick reset, and thus flexibly adapt to different motion requirements. Details are not described herein again in the present application.

[0083] The above are only the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
