Therefore, the movement contact area of the driven piece 22 and the fixed seat 10 can be reduced, and the friction force born by the driven piece 22 during movement can be reduced, so that the movement difficulty of the door 30 can be conveniently reduced, and the load of a driving motor can be conveniently reduced.

For example, the door opening and closing drive assembly 200 may be used in the fresh air component 100 of the air conditioner 1000, or may be used in other air inlet and outlet portions of the air conditioner 1000, without limitation.

For example, the driving assembly 200 is used for the fresh air component 100, the fresh air component 100 comprises a fresh air housing 101 and the driving assembly 200, the fresh air housing 101 is provided with a fresh air port 1012 for fresh air to enter and exit, the switch door 30 is located at the fresh air port 1012, and the driving assembly 200 is used for driving the switch door 30 to move so as to open or close the fresh air port 1012.

Specifically, the drive assembly 200 includes a mount 10 and a drive mechanism 20.

The fixing seat 10 can be fixedly installed on the fresh air shell 101, the driving mechanism 20 comprises a driving piece 21 and a driven piece 22, the driving piece 21 can be a driving motor, the driven piece 22 can be a transmission structure, and the transmission structure is used for converting the rotation of the output end of the driving motor into linear motion for opening and closing the door 30.

For example, the follower 22 is connected to the switch door 30 through the link 31, and the follower 22 is slidably engaged with the fixing base 10, so that when the driving member 21 drives the follower 22 to slide relative to the fixing base 10, the follower 22 can drive the switch door 30 to move relative to the fresh air housing 101 to open or close fresh air.

Further, the follower 22 is provided with a first mating surface 221, the fixing base 10 is provided with a second mating surface 11 distributed opposite to the first mating surface 221, and one of the first mating surface 221 and the second mating surface 11 is provided with a mating rib 2211 in sliding contact with the other.

Alternatively, the first mating surface 221 and the second mating surface 11 may be provided with a plurality of first mating surfaces 221 and a plurality of second mating surfaces 11, and for example, the first mating surface 221 and the second mating surface 11 may be provided with one, two, or three of the first mating surfaces 221 and the second mating surfaces 11, which are not limited herein.

It should be noted that, in the related art, the follower 22 is generally "surface-to-surface (such as the first mating surface 221 and the second mating surface 11 in the present application) contact" when sliding relative to the fixing base 10, which results in a larger moving contact area, a larger friction force, an increased difficulty in moving the door 30, and an increased load of the motor.

Therefore, in the present utility model, the follower 22 is provided with the first mating surface 221, the fixing base 10 is provided with the second mating surface 11 distributed opposite to the first mating surface 221, and one of the first mating surface 221 and the second mating surface 11 is provided with the mating rib 2211 in sliding contact with the other.

"one of the first mating surface 221 and the second mating surface 11 is provided with the mating bead 2211 in sliding contact with the other" includes that the first mating surface 221 is provided with the mating bead 2211, the mating bead 2211 is in sliding contact with the second mating surface 11, or the second mating surface 11 is provided with the mating bead 2211, the mating bead 2211 is in sliding contact with the first mating surface 221, or the first mating surface 221 and the second mating surface 11 are provided with the mating bead 2211, the mating bead 2211 of the first mating surface 221 is in sliding contact with the second mating surface 11, and the mating bead 2211 of the second mating surface 11 is in sliding contact with the first mating surface 221.

It should be noted that the engaging bead 2211 refers to a structure that is convexly disposed on one of the first engaging surface 221 and the second engaging surface 11, and an area of a contact portion of the engaging bead 2211 with the other of the first engaging surface 221 and the second engaging surface 11 is smaller than an area of the other of the first engaging surface 221 and the second engaging surface 11.

The engaging ribs 2211 may be formed separately, or the engaging ribs 2211 may be formed integrally with one of the first engaging surface 221 and the second engaging surface 11, which is not limited herein.

For example, the mating bead 2211 may be configured as a bar bead, or a dot bead, or a bead of other shape, without limitation.

Thus, when the follower 22 slides relative to the fixing base 10, the engaging bead 2211 is actually in sliding engagement with the other of the first engaging surface 221 and the second engaging surface 11, and when the engaging bead 2211 is configured as a strip-shaped bead, the two are in sliding engagement in a "line-surface contact" manner, and when the engaging bead 2211 is configured as a dot-shaped bead, the two are in sliding engagement in a "dot-surface contact" manner.

In this way, the actual moving contact area of the driven member 22 and the fixing seat 10 is the contact area of the engaging bead 2211 and the other of the first engaging surface 221 and the second engaging surface 11, and the area of the contact portion of the engaging bead 2211 and the other of the first engaging surface 221 and the second engaging surface 11 is smaller than the area of the other of the first engaging surface 221 and the second engaging surface 11, so that the moving contact area of the first engaging surface 221 and the second engaging surface 11 can be reduced, and the friction force of the driven member 22 during movement can be reduced, thereby facilitating the reduction of the movement difficulty of the opening and closing door 30, and facilitating the reduction of the load of the driving motor.

According to the driving assembly 200 for opening and closing the door of the embodiment of the present utility model, by providing one of the first mating surface 221 and the second mating surface 11 with the mating bead 2211 in sliding contact with the other, the moving contact area between the driven member 22 and the fixing base 10 is reduced, and the friction force applied to the driven member 22 during movement can be reduced, so that the difficulty in movement of the opening and closing door 30 is reduced, and the load of the driving motor is reduced.

In some embodiments, as shown in fig. 1-5, the engaging ribs 2211 are disposed on the first engaging surface 221, the engaging ribs 2211 extend along a length direction of the first engaging surface 221, and a width of the engaging ribs 2211 is smaller than a width of the first engaging surface 221.

When the engaging bead 2211 is disposed on the first engaging surface 221, the engaging bead 2211 contacts with the second engaging surface 11, so that a contact area between the driven member 22 and the fixing seat 10 is a contact area between the engaging bead 2211 and the second engaging surface 11, and a width of the engaging bead 2211 is smaller than a width of the first engaging surface 221, so that a contact area formed by the engaging bead 2211 contacting with the second engaging surface 11 is smaller than an area formed by the contact of the first engaging surface 221 and the second engaging surface 11.

Therefore, the contact area of the second mating surface 11 and the mating rib 2211 can be reduced after the second mating surface 11 contacts with the mating rib 2211, so that the friction force born by the driven member 22 when sliding relative to the fixed seat 10 can be smaller, and meanwhile, the load of the driving member 21 can be reduced and the generation of abnormal noise can be reduced through the mating rib 2211.

Meanwhile, the engaging bead 2211 extends along the length direction of the first engaging surface 221, and it should be noted that the moving direction of the driven member 22 relative to the fixing base 10 is the up-down direction of the fresh air casing 101, that is, the length direction of the first engaging surface 221, so that the engaging bead 2211 extends along the length direction of the first engaging surface 221, so that the extending direction of the engaging bead 2211 is parallel to the moving direction of the driven member 22 relative to the fixing base 10, and it is ensured that the driven member 22 can be in sliding fit with the second engaging surface 11 all the time when the driven member 22 slides relative to the fixing base 10, and thus, the contact area between the two can be reduced, and meanwhile, the moving stability of the driven member 22 can be ensured.

In some embodiments, as shown in fig. 1-5, the mating bead 2211 includes a plurality of sub-mating beads 2212 spaced apart along the width of the first mating face 221.

Therefore, the plurality of sub-fitting ribs 2212 are arranged and distributed at intervals along the width direction of the first fitting surface 221, so that the contact area of the sub-fitting ribs 2212 and the driven piece 22 is reduced, the contact area of the sub-fitting ribs 2212 and the driven piece is prevented from being too small, and the movement stability of the driven piece 22 is further ensured.

Wherein, the sub-engaging ribs 2212 may be provided with two, or three, or four, etc., and a receiving cavity 2213 for storing lubricating oil is defined between two adjacent sub-engaging ribs 2212.

For example, as shown in fig. 3 to fig. 5, two sub-matching ribs 2212 are disposed on the first matching surface 221, so that a containing cavity 2213 is defined between the two sub-matching ribs 2212, and lubricating oil can be stored in the containing cavity 2213, so that the lubricating oil in the containing cavity 2213 can lubricate the matching ribs 2211 and the second matching surface 11 in the moving process of the driven member 22, and further reduce the friction force between the matching ribs 2211 and the second matching surface 11, so as to prevent the occurrence of jamming and abnormal sounds, thereby facilitating the reduction of the moving difficulty of the switch door 30, facilitating the reduction of the load of the driving motor, and ensuring that the lubricating oil stored in the containing cavity 2213 is not easy to leak from the containing cavity 2213, thereby ensuring that the lubricating oil can be used for a long time.

In some embodiments, as shown in fig. 1-5, the driven member 22 is provided with two first contact surfaces, the two first contact surfaces are spaced apart in the width direction of the driven member 22, and two sub-engaging ribs 2212 are provided on each of the two first engaging surfaces 221, wherein the width of the sub-engaging ribs 2212 on the first engaging surface 221 near the side of the driving member 21 is greater than the width of the sub-engaging ribs 2212 on the first engaging surface 221 far from the side of the driving member 21.

For example, the width of the sub-engagement bead 2212 on the first engagement surface 221 on the side closer to the driving member 21 is greater than the width of the sub-engagement bead 2212 on the first engagement surface 221 on the side farther from the driving member 21, such that the first engagement surface 221 and the corresponding second engagement surface 221 on the side closer to the driving member 21The contact area of the contact surface is larger than that of the first contact surface 221 on the side far from the driving member 21 and the corresponding second contact surface, for example, the contact areas of the first contact surface 221 on the side close to the driving member 21 and the first contact surface 221 on the side far from the driving member 21 and the corresponding second contact surface are respectively reduced by 341mm ² And 278.5mm ² 。

Since the friction force of the first mating surface 221 near the driving member 21 is generally greater than that of the first mating surface 221 far from the driving member 21, by the above arrangement, the stresses of the two first contact surfaces can be more balanced, so that the movement stability of the driven member 22 is ensured.

In some embodiments, as shown in fig. 1-2 and 8-10, the drive assembly 200 further includes: the fixed support 23, fixed support 23 is located the follower 22 and deviates from the side of fixing base 10, and follower 22 and fixed support 23 sliding fit.

Therefore, the fixing support 23 is arranged, so that the driven member 22 can be limited on one side, deviating from the fixed seat 10, of the driven member 22, the driven member 22 is prevented from being separated from the fixed seat 10, and the movement stability of the driven member 22 is ensured.

For example, a space for accommodating the movement of the driven member 22 can be formed between the fixing bracket 23 and the fixing base 10, so that both sides of the driven member 22 are respectively slidably engaged with the fixing bracket 23 and the fixing base 10, thereby preventing the driven member 22 from being separated from the fixing base 10, and thus ensuring the movement stability of the driven member 22.

In some embodiments, as shown in fig. 1-2 and 8-10, the follower 22 is provided with a third mating surface 222, the fixed bracket 23 is provided with a fourth mating surface 231, the third mating surface 222 and the fourth mating surface 231 are slidably mated, and at least one of the third mating surface 222 and the fourth mating surface 231 is provided with an oil reservoir 2311.

By this, by providing at least one oil reservoir 2311 in one of the third mating surface 222 and the fourth mating surface 231, the contact area between the third mating surface 222 and the fourth mating surface 231 can be reduced to reduce the friction force to which the driven member 22 is subjected, and the lubricating oil in the oil reservoir 2311 can further lubricate the driven member 22.

For example, the oil storage groove 2311 may be configured as a concave oil groove, in which silicone oil may be stored, so that the oil storage groove 2311 may reduce a contact area between the third mating surface 222 and the fourth mating surface 231 while storing lubricating oil, thereby reducing friction force applied to the driven member 22 and lubricating oil in the oil storage groove 2311 may lubricate the driven member 22, as shown in fig. 8 to 10, at least one oil storage groove 2311 is provided on the third mating surface 222, or at least one oil storage groove 2311 is provided on the fourth mating surface 231, and preferably, the oil storage groove 2311 is provided on the fourth mating surface 231 in this embodiment.

In some embodiments, as shown in fig. 8-10, the oil storage groove 2311 is provided in plurality, and the plurality of oil storage grooves 2311 are spaced apart along the sliding direction of the fourth mating surface 231 with respect to the third mating surface 222.

The plurality of oil storage grooves 2311 are spaced apart on the fourth mating surface 231 with respect to the sliding direction of the third mating surface 222, that is, the plurality of oil storage grooves 2311 are spaced apart on the length direction of the fourth mating surface 231 (that is, the sliding direction of the follower 22 with respect to the fixing bracket 23), for example, the contact area between the third mating surface 222 and the fourth mating surface 231 can be reduced by 110mm by the plurality of oil storage grooves 2311 ² 。

Therefore, the plurality of oil storage grooves 2311 are distributed at intervals on the fourth matching surface 231, so that the friction force born by the driven member 22 can be further reduced, the driven member 22 moves more smoothly, the weight of the fixing support 23 is conveniently reduced due to the arrangement of the plurality of oil storage grooves 2311, and the light-weight design of the fixing support 23 is facilitated.

In some embodiments, the driving member 21 is configured as a drive motor and the driven member 22 is configured as a rack.

Therefore, the rotation of the driving motor is conveniently converted into the horizontal movement of the switch door 30, so that the movement difficulty of the switch door 30 is reduced, the driving motor and the rack are simpler, and the production cost is reduced.

For example, a gear set 24 is further disposed between the driving motor and the rack, the gear set 24 includes a driving gear and a driven gear, the driving gear is connected to an output end of the driving motor, the driving gear is meshed with the driven gear, and the driven gear is meshed with the rack, so that the driving motor can drive the rack to move through the gear set 24 when rotating, and further, the door 30 is opened and closed.

Further, the gear set 24 is fixed to the fixed base 10 through a gear set mounting seat 25, so that the gear set 24 can be driven between the driving motor and the rack.

The utility model also provides a fresh air component 100 of the air conditioner 1000.

As shown in fig. 11 to 21, a fresh air component 100 of an air conditioner 1000 according to an embodiment of the present utility model includes: fresh air housing 101, switch door 30, and drive assembly 200.

A fresh air cavity 1011 is formed in the fresh air housing 101, and the fresh air cavity 1011 is provided with a fresh air port 1012, and the driving assembly 200 is the driving assembly 200 for opening and closing the door of any one of the above embodiments, and the driving assembly 200 is adapted to drive the opening and closing door 30 to open or close the fresh air port 1012.

Therefore, the switch door 30 at the fresh air port 1012 is opened or closed through the driving assembly 200, so that the sealing effect of the switch door 30 when the fresh air port 1012 is closed is better, fresh air can not pass through the fresh air port 1012 when circulation is not needed, and fresh air circulation can be performed only after the switch door 30 is opened.

In some embodiments, as shown in fig. 3-4 and 11-21, the follower 22 includes a mating portion 223 and a stopping portion 224, the mating portion 223 is connected to the driving member 21, the stopping portion 224 is connected to the mating portion 223, and the stopping portion 224 is adapted to abut against the inner wall of the fresh air cavity 1011 when the switch door 30 moves to the maximum position relative to the fresh air housing 101.

Therefore, the movement stability of the driven piece 22 when the door 30 is driven to move can be ensured while the air inlet quantity of the fresh air port 1012 is not influenced.

For example, when the switch door 30 moves to the maximum position with respect to the fresh air case 101, two conditions are included, that is, the switch door 30 completely opens the fresh air port 1012, and that the switch door 30 completely closes the fresh air port 1012.

For example, when the driving member 21 is configured as a driving motor, the driven member 22 is configured as a rack, and the opening and closing door 30 completely closes the fresh air port 1012, the matching section of the rack and the driving motor is short, so when the opening and closing door 30 completely closes the fresh air port 1012, the stopping portion 224 abuts against the inner wall of the fresh air cavity 1011 due to the stopping portion 224, thereby realizing the limitation of the rack

As shown in fig. 3-4 and fig. 11-14, when the opening/closing door 30 is fully opened to the fresh air port 1012, the stopping portion 224 abuts against the inner wall of the fresh air chamber 1011, thereby limiting the rack. Meanwhile, the rack can be prevented from swinging in the opposite direction, and the rack and the driving motor are ensured to be matched stably.

The utility model also provides an air conditioner 1000.
