As shown in fig. 1 to 11, a damper assembly according to an embodiment of the first aspect of the present invention includes a damper body 100, a first one-way memory member 102, and a second one-way memory member 104; wherein the damper body 100 is adapted to be switched between an open state and a closed state; the first one-way memory 102 is connected to the damper body 100 and is adapted to be switched between a first initial state and a first deformed state; a second one-way memory 104 is connected to the damper body 100 and adapted to be switched between a second initial state and a second deformed state; from the first initial state to the first deformation state, the first one-way memory element 102 is suitable for driving the air door body 100 to switch from the closed state to the open state; from the second initial state to the second deformed state, the second one-way memory element 104 is adapted to drive the damper body 100 from the open state to the closed state.
According to the utility model discloses throttle subassembly of first aspect embodiment, through set up first one-way memory piece 102 and second one-way memory piece 104 on throttle body 100 respectively for when first one-way memory piece 102 switches to first deformation state by first initial condition, first one-way memory piece 102 can drive throttle body 100 and switch to the open mode by the closed state, when second one-way memory piece 104 switches to second deformation state by second initial condition, second one-way memory piece 104 can drive throttle body 100 and switch to the closed state by the open mode. Therefore, driving parts such as a stepping motor and the like are completely omitted, a complex gear transmission mechanism is simplified, and the design and manufacturing cost of the air door component is reduced. Moreover, because the first one-way memory member 102 and the second one-way memory member 104 do not have noise in the deformation process, the damper body 100 does not generate abnormal sound during the action, and the normal use of the damper assembly is ensured. In addition, in certain use environments, the first one-way memory element 102 and the second one-way memory element 104 can be deformed without heating, and energy consumption can be reduced to some extent.
With continued reference to fig. 1 to 11, in the damper assembly provided in the embodiment of the first aspect of the present invention, the damper body 100 can be switched between the open state and the closed state. Use the utility model discloses the air door subassembly that the embodiment of the first aspect provided is applied to the refrigerator for the example. When the air door body 100 is in an open state, cold air in the refrigeration air duct can be blown into the refrigeration compartment through the air door body 100; when the damper body 100 is in a closed state, the cool air in the cooling air duct is blocked by the damper body 100.
The first one-way memory 102 is connected to the damper body 100, and the first one-way memory 102 is switchable between a first initial state and a first deformation state. Since the first one-way memory member 102 is made of a one-way memory material, which is a material that can be deformed at a relatively low temperature and can return to a shape before the deformation after heating, such as a one-way memory alloy, when the first one-way memory member 102 is switched from the first initial state to the first deformation state, the first one-way memory member 102 can be deformed by heating. In the embodiment of the present invention, the number of the first one-way memory members 102 is not particularly limited as long as the above-described function can be performed.
When the first one-way memory member 102 is heated, the first one-way memory member 102 is switched from the first initial state to the first deformation state, and in this process, since the first one-way memory member 102 changes the state and is connected to the damper body 100, the first one-way memory member 102 can synchronously drive the damper body 100 to be switched from the closed state to the open state.
The second one-way memory 104 is connected to the damper body 100, and the second one-way memory 104 is switchable between a second initial state and a second deformed state. Also, since the second one-way memory element 104 is also made of a one-way memory alloy material, when the second one-way memory element 104 is switched from the second initial state to the second deformed state, the second one-way memory element 104 can be deformed by heating. In the embodiment of the present invention, the number of the second one-way memory members 104 is also not particularly limited as long as the above-described function can be performed.
When the second one-way memory element 104 is heated, the second one-way memory element 104 is switched from the second initial state to the second deformation state, and in this process, since the second one-way memory element 104 changes the state and is connected to the damper body 100, the second one-way memory element 104 can synchronously drive the damper body 100 to be switched from the open state to the closed state.
In this way, the opening or closing of the damper body 100 can be realized only by the state change of the first one-way memory member 102 and the second one-way memory member 104, thereby eliminating the need for a driving member such as a stepping motor, simplifying the structure of a driving part for driving the damper body 100 to operate, and correspondingly simplifying the structure of a relatively complex transmission gear set, thereby reducing the design and manufacturing cost of the damper assembly. Moreover, because the first one-way memory member 102 and the second one-way memory member 104 do not generate noise in the deformation process, no abnormal noise is generated when the first one-way memory member 102 and the second one-way memory member 104 drive the damper body 100 to open or close, and the normal use of the damper assembly is ensured.
Several implementations of the first one-way memory element 102 and the second one-way memory element 104 according to embodiments of the present invention are described below.
The implementation mode is as follows:
as shown in fig. 1, the damper assembly further includes a base 106; the damper body 100 is pivotally connected to the base 106; the first one-way memory element 102 and the second one-way memory element 104 are respectively disposed on the base 106 and connected to the damper body 100 through a transmission assembly.
Referring to fig. 1, the damper body 100 is hinged to the base 106, that is, the damper body 100 is rotatably connected to the base 106, and accordingly, the base 106 is provided with a corresponding opening so that the damper body 100 can avoid the opening when in an open state, and the damper body 100 can shield the opening when in a closed state.
In this implementation, the first one-way memory element 102 and the second one-way memory element 104 are disposed on the base 106 and connected to the damper body 100 through the transmission assembly, so that the damper body 100 is driven to synchronously move through the state change of the first one-way memory element 102 and the second one-way memory element 104 and the linkage action of the transmission assembly. The first one-way memory member 102 and the second one-way memory member 104 may be relatively disposed on the base 106 at a position corresponding to the air door body 100, for example, an avoidance opening may be formed on the air door body 100 to accommodate the transmission assembly, and correspondingly, the first one-way memory member 102 and the second one-way memory member 104 may be relatively disposed on the left and right sides of the base 106 corresponding to the avoidance opening.
In this implementation, the transmission assembly includes a first transmission member 108, a second transmission member 110, and a third transmission member 112; wherein, the first transmission member 108 is connected between the first one-way memory member 102 and the second one-way memory member 104; the second transmission member 110 is connected to the base 106 and is engaged with the first transmission member 108 for transmission; the third transmission member 112 is connected to the damper body 100 and is engaged with the second transmission member 110 for transmission.
With reference to fig. 1, one end of the first one-way memory element 102 is fixedly connected to the base 106, one end of the second one-way memory element 104 is also fixedly connected to the base 106, and the other end of the first one-way memory element 102 and the other end of the second one-way memory element 104 are connected by a first transmission element 108. The first transmission member 108 can be driven to move in the left-right direction as shown in fig. 1 by the state changes of the first one-way memory member 102 and the second one-way memory member 104. The second transmission member 110 is connected to the base 106 and is engaged with the first transmission member 108 for transmission, for example, the first transmission member 108 may be a rack, and correspondingly, the second transmission member 110 is provided with two tooth forms, namely a bevel tooth and a flat tooth, wherein the flat tooth is engaged with the rack for transmission, and the bevel tooth is engaged with the third transmission member 112 for rotation, so that the third transmission member 112 may also be provided with a bevel tooth engaged with the bevel tooth on the second transmission member 110, and in addition, the third transmission member 112 is further fixedly connected to the damper body 100. Therefore, the translational motion of the first transmission member 108 can be converted into the rotational motion of the damper body 100 through the meshing transmission between the second transmission member 110 and the first transmission member 108 and the meshing transmission between two parts of bevel teeth on the second transmission member 110 and the third transmission member 112. When the first transmission member 108 moves in the left-right direction as shown in fig. 1, the damper body 100 can be driven to open or close.
Of course, in other embodiments, a timing belt, a triangular belt, etc. may be connected between the first one-way memory element 102 and the second one-way memory element 104, and accordingly, a pulley, etc. may be driven by the second transmission element 110 in contact with the timing belt, the triangular belt, etc.
With continued reference to fig. 1, according to one embodiment of the present invention, the first one-way memory element 102 and the second one-way memory element 104 are helical; in a first initial state, the first one-way memory element 102 is in a stretched or natural state; in the first deformation state, the first one-way memory element 102 is in a compressed state; in a second initial state, the second one-way memory element 104 is in a stretched or natural state; in the second deformed state, the second one-way memory element 104 is in a compressed state.
In other words, in such embodiments, the first one-way memory member 102 and the second one-way memory member 104 may be provided in a spring-like shape.
Wherein the first one-way memory element 102 is in a distraction state in a first initial state and the first one-way memory element 102 is in a compression state in a first deformation state. That is, when the first one-way memory element 102 is switched from the first initial state to the first deformation state, the first one-way memory element 102 is gradually shortened, so that the first transmission element 108 moves to the left as shown in fig. 1 under the elastic restoring force of the first one-way memory element 102, and at this time, the second transmission element 110 rotates clockwise and synchronously drives the third transmission element 112 to rotate, and the damper body 100 is gradually opened along with the rotation of the third transmission element 112.
The second one-way memory 104 is in a nerved state in a second initial state, and the second one-way memory 104 is in a compressed state in a second deformed state. That is, when the second one-way memory element 104 is switched from the second initial state to the second deformed state, the second one-way memory element 104 is gradually shortened, so that the first transmission element 108 moves to the right side as shown in fig. 1 under the elastic restoring force of the second one-way memory element 104, at this time, the third transmission element 112 rotates counterclockwise and synchronously drives the third transmission element 112 to rotate reversely, and the damper body 100 is gradually closed along with the rotation of the third transmission element 112.
By so doing, the opening or closing of the damper body 100 can be completed by the state change of the first one-way memory member 102 and the second one-way memory member 104.
Of course, the first one-way memory member 102 and the second one-way memory member 104 may also be provided in the shape of a bar, a sheet, or the like.
The second implementation mode:
this implementation differs from the first implementation in that: a portion of the first one-way memory 102 and a portion of the second one-way memory 104 are connected to the base 106; a portion of the first one-way memory 102 and a portion of the second one-way memory 104 are connected to the damper body 100.
As shown in fig. 2 to 11, a part of the first one-way memory 102 is connected to the base 106, and a part of the first one-way memory 102 is connected to the damper body 100; similarly, a portion of the second one-way memory 104 is connected to the base 106, and a portion of the second one-way memory 104 is connected to the damper body 100. The first one-way memory member 102 and the second one-way memory member 104 can be connected to the base 106 and the damper body 100 by clamping, bonding, and the like.
In this implementation, the first one-way memory member 102 and the second one-way memory member 104 are sheet-shaped; in a first initial state, the first one-way memory element 102 is in a flat state; in the first deformed state, the first one-way memory element 102 is in a bent state; in a second initial state, the second one-way memory element 104 is in a bent state; in the second deformed state, the second one-way memory element 104 assumes a flat state.
As shown in fig. 2 and 3, the first one-way memory member 102 and the second one-way memory member 104 may be provided in a sheet shape. Wherein the first one-way memory member 102 is in a flat state in the first initial state, and the first one-way memory member 102 is in a curved state in the first deformed state. That is, when the first one-way memory member 102 is switched from the first initial state to the first deformation state, the first one-way memory member 102 is gradually restored to the bent state, and thus the damper body 100 is gradually opened by the first one-way memory member 102.
The second one-way memory 104 is in a curved state in the second initial state, and the second one-way memory 104 is in a flat state in the second deformed state. That is, when the second one-way memory 104 is switched from the second initial state to the second deformed state, the second one-way memory 104 is gradually restored to the flat state, and thus the damper body 100 is gradually closed by the second one-way memory 104.
By so doing, the opening or closing of the damper body 100 can be completed by the state change of the first one-way memory member 102 and the second one-way memory member 104.
The third implementation mode is as follows:
this implementation differs from the second implementation in that: in this implementation, as shown in fig. 4 to 11, the first one-way memory member 102 and the second one-way memory member 104 may be arranged in a bar shape. The plane of the first one-way memory member 102 on the base 106 is parallel to the plane of the first one-way memory member 102 on the damper body 100, and in the first deformation state, the plane of the first one-way memory member 102 on the base 106 and the plane of the first one-way memory member 102 on the damper body 100 are inclined to each other. That is, when the first one-way memory element 102 is switched from the first initial state to the first deformation state, the first one-way memory element 102 can drive the damper body 100 to be switched from a state parallel to the base 106 to a state inclined to the base 106, and at this time, the damper body 100 is gradually switched to the open state.
In the second initial state, the plane of the second one-way memory 104 on the base 106 and the plane of the second one-way memory 104 on the damper body 100 are inclined to each other, and in the second deformed state, the plane of the second one-way memory 104 on the base 106 and the plane of the second one-way memory 104 on the damper body 100 are parallel to each other. That is, when the second one-way memory 104 is switched from the second initial state to the second deformed state, the second one-way memory 104 can drive the damper body 100 to be switched from a state of being inclined with respect to the base 106 to a state of being parallel with respect to the base 106, and at this time, the damper body 100 is gradually switched to the closed state.

Wherein, the heating member can be one or a plurality of. When one heating member is provided, the heating member is connected to the first one-way memory member 102 and the second one-way memory member 104, respectively; when the heating member is plural, the plural heating members may be connected to the first one-way memory member 102 and the second one-way memory member 104 in one-to-one correspondence.
The heating element may be an external power source and is connected to the first one-way memory element 102 and the second one-way memory element 104, that is, when the first one-way memory element 102 and the second one-way memory element 104 are energized, the temperatures of the first one-way memory element 102 and the second one-way memory element 104 are increased, and the states of the first one-way memory element 102 and the second one-way memory element 104 are changed.
Alternatively, the heating element may be a heating wire attached to the first one-way memory element 102 and the second one-way memory element 104, respectively, so that the first one-way memory element 102 and the second one-way memory element 104 change their states when the heating wire is heated.
Of course, in other embodiments, no heating element may be provided, for example, in a closed compartment, the first one-way memory element 102 and the second one-way memory element 104 may be driven to change states as the ambient temperature of the compartment increases or decreases.
