Abstract

A deflector rod includes a linkage member configured to drive a louver of an air outlet frame to rotate and a shift member connected with the end of the linkage member. The linkage member includes a first limiting projection provided at one end of the linkage member. The shift member includes a groove extending between two opposite ends of the shift member and a second limiting projection provided at a side wall of the groove away from the linkage member. Both the second limiting projection and the first limiting projection are spaced apart from a bottom wall of the groove. The groove, the first limiting projection, and the second limiting projection are configured to clamp an air guide bar of the air outlet frame such that the air guide bar is at least partially located in the groove, between the second limiting projection and the bottom wall of the groove, and between the first limiting projection and the bottom wall of the groove.

First claim

What is claimed is:

a first limiting projection provided at a side of the linkage member; and
a shift member connected with the side of the linkage member, and including:
a groove extending between two opposite ends of the shift member; and
a second limiting projection provided at a side wall of the groove away from the linkage member;

wherein:
both the second limiting projection and the first limiting projection are spaced apart from a bottom wall of the groove;
the groove, the first limiting projection, and the second limiting projection are configured to clamp an air guide bar of the air outlet frame such that the air guide bar is at least partially located in the groove, between the second limiting projection and the bottom wall of the groove, and between the first limiting projection and the bottom wall of the groove; and
the linkage member extends in a length direction of the air guide bar and includes a plurality of accommodation notches spaced apart from each other in a length direction of the linkage member.

2. The deflector rod according to claim 1 , wherein the first limiting projection includes a guide slope at an end surface of the first limiting projection distal from an inner side wall of the groove, and the guide slope is inclined away from the linkage member in a direction from an opening of the groove to the bottom wall of the groove.

3. The deflector rod according to claim 1 , further comprising:
a connection member including:
a first end connected with the side of the linkage member proximal to the shift member; and
a second end extending in a direction away from the bottom wall of the groove and connected with the first limiting projection.

4. The deflector rod according to claim 3 , further comprising:
an elastic member;
wherein:
the linkage member includes a recess at the side of the linkage member proximal to the shift member;
a first end of the elastic member in a longitudinal direction of the elastic member is connected with a bottom wall of the recess and a second end of the elastic member is connected with the connection member; and
both sides of the elastic member in a width direction of the elastic member are spaced apart from an inner peripheral wall of the recess.

5. The deflector rod according to claim 1 , wherein the second limiting projection includes a guide slope at an end surface of the second limiting projection away from an inner side wall of the groove, the guide slope being inclined toward the linkage member in a direction from an opening of the groove to the bottom wall of the groove.

6. The deflector rod according to claim 1 , wherein the shift member includes a plurality of shift ribs at an outer side wall of the shift member away from the linkage member, the plurality of shift ribs being spaced apart from each other.

7. An air outlet frame assembly comprising:
an air outlet frame including an air outlet channel and an air guide bar provided in the air outlet channel and extending in a length direction of the air outlet channel; and
a louver rotatably provided at the air outlet frame and located upstream of the air guide bar in an air flow direction; and
a deflector rod including:
a linkage member configured to drive the louver to rotate, and including a first limiting projection provided at a side of the linkage member, another side of the linkage member being connected with an end of the louver proximal to the air guide bar; and
a shift member connected with the side of the linkage member, and including:
a groove extending between two opposite ends of the shift member; and
a second limiting projection provided at a side wall of the groove away from the linkage member;

wherein:
both the second limiting projection and the first limiting projection are spaced apart from a bottom wall of the groove;
the air guide bar is at least partially located in the groove, between the first limiting projection and a bottom wall of the groove, and between the second limiting projection and the bottom wall of the groove;
the air outlet channel further includes a plurality of reinforcing rib plates extending in a width direction of the air outlet channel and spaced apart from each other in the length direction of the air outlet channel; and
the air guide bar is connected with the plurality of reinforcing rib plates.

8. The air outlet frame assembly according to claim 7 , wherein:
the air outlet frame includes a first mounting member and a second mounting member at two ends of the air outlet frame in a width direction of the air outlet frame, respectively, the first mounting member including:
a recess located at an air inlet end of the air outlet frame; and
a mounting portion in the recess, two ends of the mounting portion in a longitudinal direction of the mounting portion being connected with two opposite inner side walls of the recess, respectively, a rest part of the mounting portion being spaced apart from an inner wall of the recess, and the mounting portion including a mounting hole configured to mount the louver and including a mounting notch; and

the louver includes a first rotation member in the mounting hole and a second rotation member fitted with the second mounting member.

9. The air outlet frame assembly according to claim 8 , wherein in a direction toward the mounting notch, the width of the mounting hole is increased gradually and then decreased gradually.

10. The air outlet frame assembly according to claim 8 , wherein:
the recess includes:
a first sub-recess formed at the air inlet end of the air inlet frame; and
a second sub-recess formed at a bottom wall of the first sub-recess, and a maximum width of the notch sub-recess being less than a minimum width of the first sub-recess;

the mounting portion includes a first segment, a second segment, and a third segment connected successively;
the second segment is opposite to the second sub-recess to form the mounting hole;
