Based on the heat conduction of air, when the air deflector 50 is opened downwards, hot air flows downwards along the air deflector 50, so that heat exchange with cold air in a room can be better performed.

The structure and the movement process of the link assembly will be described below using the link assembly on the right side of the wind deflector 50 as an example.

In some embodiments, the link assembly for the air deflector 50 includes a first link 20, a second link 30, and a track plate 40, one end of the first link 20 is rotatably connected to the air deflector 50, and the first link 20 includes a first limiting portion; one end of the second connecting rod 30 is rotationally connected with the air deflector 50, and the second connecting rod 30 comprises a second limiting part; the track plate 40 includes a first track and a second track, the first limiting portion is slidably disposed on the first track and the second track, the second limiting portion is slidably disposed on the second track, and the track plate 40 is used for defining movement tracks of the first link 20 and the second link 30; the first rail includes an arc-shaped rail 42 extending in a direction, so that the first link 20 is driven by an external force to cooperate with the second link 30, and the air deflector 50 is translated to extend out of the air outlet and then opened downwards for attaching air supply.

The movement mechanism provided by the embodiment of the present disclosure includes a first link 20, a second link 30, and a rail plate 40, the rail plate 40 being provided with a first rail and a second rail. The first limiting portion of the first link 20 is simultaneously matched with the first rail and the second rail, the second limiting portion of the second link 30 is matched with the second rail, and the first rail is provided with an arc-shaped rail 42. In this way, the track plate 40 can limit the movement track of the first link 20 and the second link 30, so that the first link 20 can drive the air deflector 50 to extend out of the air outlet and then to open downwards under the driving of external acting force, and the air flow blown out from the air outlet can form jet flow to blow to the ground after reaching the air deflector 50, so as to carry out attached air supply, so that the room can reach the preset temperature as soon as possible, and the heating effect of the heating device is improved. Meanwhile, the air supply range of the air flow blown out along the air deflector 50 is larger, so that the air quantity in unit area is reduced, the air supply is softer, and the comfort level of a user is improved. In addition, in the connecting rod assembly provided by the embodiment of the disclosure, the first connecting rod 20 can extend and rotate the air deflector 50 under the action of an external force, so that the structure of the connecting rod assembly is simplified, and the effect of long-distance and large-range air supply is realized.

Alternatively, a vertical projection line of a straight line of the connection point of the first link 20 and the air deflector 50 along the extending direction of the air deflector 50 on the track plate 40 is taken as a reference line, the initial end of the arc track 42 is disposed on the reference line, and the tail end of the arc track 42 is disposed on the upper side of the reference line.

As shown in fig. 3, the vertical projection line of the straight line of the connection point of the first link 20 and the air guide plate 50 along the extending direction of the air guide plate 50 on the track plate 40 is AB, that is, the above-mentioned reference line, and the reference line is considered as a horizontal straight line, then the end of the arc track 42 is located above the reference line AB. That is, the arc-shaped orbit 42 is shaped like a "herringbone" and the arc-shaped orbit 42 extends from the reference line AB to the upper side of the reference line AB.

Optionally, the first track further includes a first linear track 41, where the first linear track 41 is disposed along the reference line in a straight line and is in communication with the start end of the arc track 42; the first connecting rod 20 moves along the first linear track 41 to drive the air deflector 50 to translate and extend out of the air outlet to a first preset position, then the first connecting rod 20 enters the initial end of the arc track 42 and moves along the arc track 42, and the second connecting rod 30 moves along the second track to drive the air deflector 50 to open downwards.

In the embodiment of the disclosure, the first preset position is a position where the air deflector 50 horizontally extends out of the air outlet and is about to start rotating, as shown in fig. 12, at this time, a certain distance is provided between the air deflector 50 and the air outlet, and the air deflector 50 can be opened upwards at the first preset position. In the embodiment of the present disclosure, the rotational position of the air deflector 50 is not limited to the first preset position, which is the initial position of the air deflector 50 rotating, and the rotation of the air deflector 50 can be understood as rotating while extending.

In the embodiment of the disclosure, the driving element provides a driving force for the movement of the first link 20, and since the first link 20 and the second link 30 are both rotationally connected with the air deflector 50, the driving force is transmitted to the second link 30 through the first link 20, so that the second link 30 can also follow the first link 20 to move linearly synchronously, and jointly drive the air deflector 50 to move horizontally and stretch out to the first preset position, and then the first link 20 moves along the arc-shaped track 42, the second link 30 continues to move along the linear track of the track plate 40, and the first link 20 and the second link 30 generate relative movement, so as to drive the air deflector 50 to open downwards.

Optionally, the first limiting portion includes at least two sliding posts. Optionally, a sliding column is disposed in both the first rail and the second rail.

As shown in fig. 7, the first limiting portion includes a first sliding column 25 and a second sliding column 26, the first sliding column 25 is disposed at the top end of the first link 20, and the second sliding column 26 is disposed at the middle of the first link 20. The first sliding column 25 is slidably disposed in the first rail, and the second sliding column 26 is slidably disposed in one of the linear rails. When the first sliding column 25 moves from the first linear rail 41 to the arc-shaped rail 42, the second connecting rod 30 moves linearly along the second rail, the first connecting rod 20 and the second connecting rod 30 move relatively, the first connecting rod 20 changes direction, and the second connecting rod 30 cooperates with the first connecting rod 20 to drive the air deflector 50 to open downwards.

Optionally, the second limiting portion at least comprises two sliding columns, and the sliding columns are slidably arranged in the second track.

As shown in fig. 8, the second limiting portion of the second link 30 includes a third sliding column 31, a fourth sliding column 32, and a fifth sliding column 33, which are arranged in a triangle shape. In this way, the limiting effect of the track plate 40 on the movement trace of the second link 30 is improved.

Optionally, the first linear rail 41 includes a linear section and a transition section, the transition section is disposed at a connection position between the linear section and the arc rail 42, and two sides of the transition section are disposed in an arc shape along a direction extending toward the arc rail 42, and the transition section is used for avoiding abrupt acceleration of the air deflector 50 at a first preset position.

As shown in fig. 3, the straight line segment and the transition segment are respectively illustrated by dotted lines in fig. 3, the initial segment of the first straight line track 41 is the straight line segment, and the portion of the first straight line track 41 enclosed by the dotted lines is the transition segment. If the first linear rail 41 is not provided with a transition section, the rotational speed of the wind deflector 50 is suddenly increased at the first preset position. Visually, the air deflector 50 is suddenly changed from a translationally extended state to a rapidly rotated state, thus directly affecting the user experience. After the transition section is arranged on the first linear track 41, the air deflector 50 can gradually start to rotate from a translational extension state, sudden acceleration can not occur, and the precise control degree of the movement process of the air deflector 50 is improved.

Alternatively, the time ratio of the movement of the first link 20 along the first straight rail 41 and the arc-shaped rail 42 is greater than or equal to 0.5 and less than or equal to 0.7.

By limiting the ratio of the time of movement of the first sliding column 25 in the first linear rail 41 and the arc-shaped rail 42, the air deflector 50 can be rotated at a moderate speed during the upward opening. Meanwhile, the air deflector 50 can also extend out of a proper distance and then rotate, so that the air deflector 50 is prevented from touching the shell of the heating device. For example, the time ratio of movement of the first sliding column 25 within the first linear rail 41 and the arc-shaped rail 42 may be 2:3, or 3:5, or the like.

Optionally, the second track includes a plurality of parallel linear tracks, and the plurality of linear tracks are disposed on the underside of the arcuate track 42.

Alternatively, the second rail includes a second linear rail 44, a third linear rail 45, and a fourth linear rail 46, where the second linear rail 44 is disposed along the direction in which the air guide plate 50 extends and is located on the reference line with the first linear rail 41; the third linear rail 45 is disposed at one side of the second linear rail 44; the fourth linear rail 46 is disposed at the other side of the second linear rail 44; wherein the second linear rail 44, the third linear rail 45 and the fourth linear rail 46 are all located at the lower side of the first rail.

Optionally, the second linear rail 44, the third linear rail 45 and the fourth linear rail 46 are rail grooves penetrating the rail plate 40. Thus, the second sliding post 26 and the three sliding posts of the second limiting portion can stably slide in the track groove, and stability of movement of the connecting rod in the track is improved. Wherein the third sliding column 31 moves in the second linear rail 44, the fourth sliding column 32 moves in the third linear rail 45, and the fifth sliding column 33 moves in the fourth linear rail 46.

Optionally, the second link 30 is further provided with a through-slide 35 extending through the face of the second link 30. The second link 30 is provided with a through-slide 35 so that the second sliding post 26 of the first link 20 can move along the second track through the through-slide 35.

Alternatively, the first link 20 is provided with a through groove 21, and the driving shaft 121 of the crank 10 is slidably disposed in the through groove 21 to provide a driving force for the movement of the first link 20.

Alternatively, the through groove 21 is linear, and the diameter of a circle formed by the movement of the transmission shaft 121 of the crank 10 is smaller than or equal to the length of the through groove 21. In this way, the transmission shaft 121 of the crank 10 can be rotated 90 ° in the first direction or the second direction from the initial position, and then the rotation is continued, and the rotation angle of the crank 10 is not limited by the length of the through groove 21.

Optionally, the first link 20 further includes a hollowed-out area 22, the hollowed-out area 22 is disposed above the through groove 21, and a distance between an edge of the hollowed-out area 22 and an outer edge of the first link 20 is greater than or equal to 0.5 mm.

As shown in fig. 6, the hollowed-out area 22 is disposed above the through groove 21, and the first connecting rod 20 is light due to the arrangement of the hollowed-out area 22, so that the moment of the motor can be reduced in the process of driving the crank to drive the first connecting rod 20 to move. Meanwhile, limiting the size of the hollowed-out area 22 can also enable the first link 20 to have movement reliability.

Optionally, the center of the circle of the arc-shaped track 42 is located at the lower side of the arc-shaped track 42, so that the air deflector 50 rotates at a constant speed in the downward opening process.

In the embodiment of the disclosure, the center of the circle where the arc-shaped rail 42 shown in fig. 3 is located at the lower side of the arc-shaped rail 42, that is, the shape of the arc-shaped rail 42 is convex, so that the air deflector 50 can rotate at a uniform speed in the downward opening process, and the situation that the air deflector 50 rotates rapidly to open downward after extending out of the air outlet is avoided.

Another track plate 40 is also provided by embodiments of the present disclosure, as shown in fig. 4. The curved direction of the arc-shaped rail 42 in the two rail plates 40 shown in fig. 3 and 4 is different. The arc-shaped rail 42 shown in fig. 4 is concave, that is, the center of the circle in which the arc-shaped rail 42 is located at the upper side of the arc-shaped rail 42.

The two arc-shaped rails 42 with different shapes are different in motion trail which is matched with other parts of the connecting rod assembly to drive the air deflector 50 to move, and the bending direction of the arc-shaped rails 42 can influence the speed of the air deflector 50 in the rotating process. The arcuate rails 42 of the rail plate 40 shown in fig. 3 are outwardly convex so that the deflector 50 can rotate at a constant speed after extending out of the air outlet. The arcuate track 42 of the track plate 40 shown in fig. 4 is concave, so that the air deflector 50 rotates faster and faster after extending out of the air outlet, and the air deflector 50 opens downward rapidly, directly affecting the sensory experience of the user.

In order to more intuitively reflect the rotation speed of the air deflector 50 after extending out of the air outlet, the embodiment of the disclosure provides a comparison schematic diagram of the rotation speed of the air deflector 50 driven by the two kinds of track boards 40 by the movement mechanism in fig. 5. The rotational speed of the wind deflector 50 is understood to be the rotational angular speed.

As shown in fig. 5, the solid line in the drawing shows the variation of the rotational speed of the wind deflector 50 using the track plate 40 shown in fig. 3 with time. In the period of 0-2 seconds, the rotation speed of the air deflector 50 is 0, which indicates that the air deflector 50 does not rotate in the extending process; in the period of 2-4 seconds, the rotation speed of the air deflector 50 starts to gradually increase, which means that the air deflector 50 gradually starts to rotate after extending out of the air outlet; the rotational speed of the air deflector 50 is maintained during the period of 4-10 seconds, indicating that the air deflector 50 can be maintained in a substantially constant speed during rotation.

As shown in fig. 5, the dotted line in the drawing shows the variation of the rotation speed of the wind deflector 50 using the track plate 40 shown in fig. 4 with time. In the period of 0-2 seconds, the rotation speed of the air deflector 50 is 0, which indicates that the air deflector 50 does not rotate in the extending process; in the period of 2-4 seconds, the rotation speed of the air deflector 50 begins to gradually increase, which means that the air deflector 50 begins to rotate after extending out of the air outlet; the rotational speed of the air deflection 50 increases gradually over a period of 4-10 seconds, indicating that the air deflection 50 is increasing in speed during rotation.

By comparing the simulation experimental data of the rotational speed of the air deflector 50, which is shown in fig. 5 and is tested by adopting two kinds of track boards 40, it can be seen from the rotational speed curve of the air deflector 50 in the 4-10 second time period that the track board 40 with the outer convex arc track 42 provided by the embodiment of the disclosure can be matched with other components of the connecting rod assembly, and drives the air deflector 50 to rotate at a constant speed after extending out of the air outlet, so that the phenomenon that the air deflector 50 is faster and faster in the rotation process is avoided, and the sensory experience of users is improved.

Alternatively, the arc of the arcuate track 42 is greater than or equal to 10 ° and less than or equal to 25 °. In this way, the air deflector 50 can be rotated to the maximum opening angle at a constant speed after extending out of the air outlet.

Optionally, a limiting mechanism is disposed between the first link 20 and the second link 30, and the limiting mechanism is used for preventing the second link 30 from shaking during the movement of the air deflector 50.

During the movement of the air deflector 50, only one end of the second connecting rod 30 is limited with the air deflector 50, and during the movement of the air deflector 50, if the second connecting rod 30 is shifted by hand, the second connecting rod 30 can shake up and down, so that the reliability of the second connecting rod 30 is lower. In addition, the second link 30 swings up and down and also affects the normal movement of the wind deflector 50, reducing the reliability of the whole movement mechanism.

Optionally, the limiting mechanism includes a limiting post 36 and a positioning slot 23, where the limiting post 36 is disposed on the second link 30; the positioning groove 23 is obliquely arranged on the first connecting rod 20, and the limit column 36 is slidably arranged in the positioning groove 23; wherein, during the downward opening of the wind deflector 50, the limit post 36 slides in the positioning groove 23 to define the position of the second link 30.

No matter where the air deflector 50 moves, the limiting post 36 is always in the positioning groove 23, so that the user cannot dial the second connecting rod 30 by hand, and the reliability of the second connecting rod 30 is improved.

Alternatively, the second link 30 has a first plate surface opposite to the first link 20, and the limit post 36 is disposed on the first plate surface and located on an upper portion of the second link 30, as shown in fig. 9.

Alternatively, the first link 20 has a limiting plate surface opposite to the second link 30, and the positioning slot 23 is disposed in the middle of the limiting plate surface.

When the air deflector 50 is in the closed state, the first link 20 and the second link 30 in the movement mechanism of the embodiment of the present disclosure are in a partially abutted state. The second link 30 has a first plate surface opposite to the first link 20, and the first link 20 has a stopper plate surface opposite to the second link 30. The limit post 36 is located at the upper part of the first plate surface of the second link 30, and the positioning groove 23 is located at the middle part of the limit plate surface of the first link 20, that is, the middle lower part of the first link 20 is abutted with the second link 30. In addition, in the movement process of the air deflector 50, the limit post 36 is always positioned in the positioning groove 23, and the upper end of the second connecting rod 30 is always kept in a limit state, so that the second connecting rod 30 is prevented from shaking.

Alternatively, the upper side edge of the positioning groove 23 is linear. When the air deflector 50 is in a closed state, the limit post 36 of the second connecting rod 30 is positioned at the lower end of the positioning groove 23, and when the air deflector 50 is opened downwards to a maximum angle, the limit post 36 is positioned at the upper end of the positioning groove 23. It can be understood that the shape of the positioning groove 23 is the changing track of the abutment point between the limit post 36 of the second link 30 and the first link 20. The upper end of the second connecting rod 30 is limited through the change track, so that a user cannot stir the second connecting rod 30 by hand, and the reliability of the connecting rod assembly is improved.

In the disclosed embodiment, both the first link 20 and the second link 30 are rotatably coupled to the air deflector 50.

Alternatively, one end of the first link 20 is provided with a first connection hole 27, and one end of the second link 30 is provided with a second connection hole 34.

Optionally, a connecting piece 60 is disposed between the first connecting rod 20 and the second connecting rod 30 and the mounting seat 52 of the air deflector 50, the connecting piece 60 is hinged with the first connecting hole 27 and the second connecting hole 34 respectively, and the connecting piece 60 is clamped with the mounting seat 52, as shown in fig. 12.

The first connecting hole 27 is hinged to the first mounting portion 61, and the second connecting hole 34 is clamped to the second mounting portion 62. By arranging the connecting piece 60 between the mounting seat 52 of the air deflector 50 and the first connecting rod 20 and the second connecting rod 30, the air deflector 50 can be conveniently disassembled and assembled, and the assembly efficiency of the air deflector 50 is improved.

The movement mode of the movement mechanism for the air deflector 50 provided in the embodiment of the present disclosure is as follows:

the initial state of the link assembly of the air deflection 50 in the closed condition is shown in fig. 2. When the crank 10 rotates in the first direction, the transmission shaft 121 slides in the through groove 21 of the first link 20 to move the first link 20 and the second link 30. The first connecting rod 20 moves along the straight line segment of the first straight line track 41, and the second connecting rod 30 moves along the second track, so as to drive the air deflector 50 to extend to the first preset position in a straight line motion. The first preset position may be understood as a position of the wind deflector 50 corresponding to when the first sliding column 25 of the first link 20 moves to the end of the straight line segment, as shown in fig. 13. In the embodiment of the present disclosure, the first direction is a counterclockwise direction based on the illustration of fig. 13.

When the air deflector 50 reaches the first preset position, the transmission shaft 121 continues to slide in the through groove 21 to drive the first sliding column 25 of the first link 20 to enter the transition section of the first linear rail 41 and move along the arc-shaped rail 42, and the second sliding column 26 of the first link 20 continues to move in the second rail, so that the first link 20 starts to move and turn, and the first link 20 and the second link 30 move relatively to each other, so as to jointly drive the air deflector 50 to open downwards, thereby meeting the air supply requirement of the heating device, as shown in fig. 14.
