The convergence rod is located above the air guide plate and is rotatably connected to the air outlet frame. By adjusting the rotation angle of the convergence rod relative to the air outlet frame, the air circulation above the air guide plate can be adjusted.

Specifically, a D-shaped hole is set at the end of the polymer rod, and the output shaft of the drive mechanism is connected to the D-shaped hole to transmit torque. The polymer rod is heavy, and a large torque is required to drive the polymer rod to rotate. In actual use, it is found that the D-shaped hole at the end of the polymer rod is severely worn and easily deformed, such as becoming a round hole, which makes it impossible to transmit torque between the output shaft of the drive mechanism and the polymer rod, and the drive of the polymer rod fails.

[0032] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Combine the following Figures 1 to 8 The polymer rod device of the present invention is described.

[0034] like Figures 1 to 8 As shown, the polymer rod device provided by the embodiment of the utility model includes a polymer rod 1 and a driving mechanism.

[0035] Specifically, the aggregate rod 1 is rotatably disposed at the air outlet of the air outlet frame 2 , and the driving mechanism is used to drive the aggregate rod 1 to rotate relative to the air outlet frame 2 .

[0036] A connecting hole 3 is provided at one end of the polymer rod 1, and a side wall of the connecting hole 3 has at least two first force-bearing planes 4, and each first force-bearing plane 4 is parallel to each other or each first force-bearing plane 4 is arranged at an angle.

[0037] The outer surface of the output end of the driving mechanism has a second force-bearing plane 5 , and the second force-bearing plane 5 is arranged in abutment with the first force-bearing plane 4 in a one-to-one correspondence.

[0038] With such arrangement, when the output end of the driving mechanism is connected to the polymer rod 1, there are at least two force-bearing planes between the output end of the driving mechanism and the polymer rod 1. Compared with the D-type shaft and the D-type hole in the prior art, the force-bearing area is increased, the ability to transmit torque is improved, the reliability is enhanced, and the problem of wear and deformation of the connecting hole 3 can be reduced, thereby reducing the probability of failure to transmit torque between the output shaft of the driving mechanism and the polymer rod 1, and avoiding the problem of drive failure of the polymer rod 1.

[0039] It should be noted that the other end of the aggregation rod 1 is directly connected to the air outlet frame 2 for rotation. Specifically, a rotating shaft can be set at the other end of the aggregation rod 1, and a shaft sleeve can be set on the air outlet frame 2. The rotating shaft can extend into the interior of the shaft sleeve, and the rotating shaft can rotate around a fixed axis inside the shaft sleeve.

[0040] In the embodiment of the utility model, the side wall of the connecting hole 3 has two first force planes 4, which are parallel to each other. Correspondingly, the outer surface of the output end of the driving mechanism has two second force planes 5, which are parallel to each other.

[0041] The connecting hole 3 can be a rectangular hole or a waist-shaped hole.

[0042] In this embodiment, the connection hole 3 is set as a waist-shaped hole. Figure 7 .

[0043] Specifically, the setting position and angle of a first force plane 4 of the waist-shaped hole on the polymer rod 1 can be made consistent with the setting position and angle of the force plane of the D-shaped hole on the polymer rod in the prior art, and the distribution direction of the two first force planes 4 of the waist-shaped hole is consistent with the distribution direction of the force plane and the force curved surface of the D-shaped hole in the prior art. During production, the processing mold of the polymer rod in the prior art can be modified, and the polymer rod 1 in this embodiment can be processed using the modified mold. During modification, only the position of the mold corresponding to the waist-shaped hole needs to be modified, and the other positions do not need to be changed. The design amount is small, and the processing mold can continue to be used, avoiding waste, and the improvement cost is low.

[0044] In this embodiment, the driving mechanism includes a connecting shaft 6 and a driving member 7 .

[0045] The driving member 7 is disposed on the air outlet frame 2, the connecting shaft 6 is rotatably disposed on the air outlet frame 2, and the second force-bearing plane 5 is disposed on the first end of the connecting shaft 6, so that the first end of the connecting shaft 6 is connected to the polymer rod 1. The second end of the connecting shaft 6 is connected to the output shaft of the driving member 7, and the driving member 7 is used to drive the connecting shaft 6 to rotate relative to the air outlet frame 2.

[0046] The air outlet frame 2 is provided with a mounting hole, and the connecting shaft 6 is loosely matched with the mounting hole to ensure that the connecting shaft 6 can rotate relative to the air outlet frame 2. Specifically, the axis of the mounting hole is parallel to the axis direction of the polymer rod 1, so that the mounting hole passes through the air outlet frame 2 in a direction perpendicular to the axis of the polymer rod 1, so that the mounting hole is in the form of an open slot structure, which is convenient for the disassembly and assembly of the polymer rod 1 and the connecting shaft 6. When installing the polymer rod device on the air outlet frame 2, first connect the polymer rod 1 and the connecting shaft 6 together, then insert the rotating shaft at one end of the polymer rod 1 into the bushing on the air outlet frame 2, and make the other end of the polymer rod 1 close to the mounting hole, so that the connecting shaft 6 at the other end of the polymer rod 1 enters the mounting hole in a direction perpendicular to the axis of the mounting hole, and then install the driving member 7 on the air outlet frame 2, and connect the output shaft of the driving member 7 with the second end of the connecting shaft 6. When it is necessary to remove the aggregation rod device from the air outlet frame 2, the driving member 7 can be removed from the air outlet frame 2 first, so that the aggregation rod 1 drives the connecting shaft 6 away from the mounting hole to make the connecting shaft 6 detach from the mounting hole, and then the rotating shaft of the aggregation rod 1 can be pulled out from the shaft sleeve of the air outlet frame 2.

[0047] The driving member 7 may be, but is not limited to, a motor. The housing of the motor is fixedly connected to the air outlet frame 2 , and the output shaft of the motor is connected to the connecting shaft 6 .

[0048] Specifically, a waist-shaped hole can be provided at the second end of the connecting shaft 6, and the cross-sectional shape of the output shaft of the motor can be set to a waist shape, so that the output shaft of the motor is interference-fitted with the waist-shaped hole at the second end of the connecting shaft 6. In this way, the ability to transmit torque between the motor and the connecting shaft 6 can be increased.

[0049] In the embodiment of the utility model, a first mark 8 is provided on the end surface of the polymer rod 1 close to the driving mechanism, and a second mark is provided on the connecting shaft 6, and the first mark 8 corresponds to the second mark.

[0050] When connecting the connecting shaft 6 with the polymer rod 1, by comparing the first mark 8 with the second mark, it can be ensured that the relative position angle of the connecting shaft 6 and the polymer rod 1 is correct, thereby avoiding the problem that the polymer rod 1 cannot rotate smoothly due to the wrong relative position angle of the connecting shaft 6 and the polymer rod 1.

[0051] In this embodiment, a first limiting protrusion 9 and a second limiting protrusion 10 are provided on the air outlet frame 2, and a third limiting protrusion 11 is provided on the connecting shaft 6. The aggregation rod 1 can rotate between a first position and a second position, and when the aggregation rod 1 rotates to different positions, the regulating effect on the air circulation above the air guide plate is different.

[0052] When the polymer rod 1 rotates to the first position, the third limiting protrusion 11 abuts against the first limiting protrusion 9. When the polymer rod 1 rotates to the second position, the third limiting protrusion 11 abuts against the second limiting protrusion 10.

[0053] Through the interaction between the first limiting protrusion 9 and the third limiting protrusion 11 and the interaction between the second limiting protrusion 10 and the third limiting protrusion 11, the rotation angle of the connecting shaft 6 can be limited within a certain range, so that the polymer rod 1 can rotate within a certain angle range.

[0054] Along the axial direction of the connecting shaft 6 , the projection area of ​​the third limiting protrusion 11 is located outside the projection area of ​​the connecting shaft 6 . It can be understood that the third limiting protrusion 11 protrudes from the outer peripheral surface of the connecting shaft 6 .

[0055] The third limiting protrusion 11 can be regarded as a second mark. By using the third limiting protrusion 11 as the second mark, it is possible to avoid separately processing the second mark on the connecting shaft 6, simplify the structure of the connecting shaft 6, and reduce the processing difficulty.

[0056] In this embodiment, the first mark 8 extends along an arc, and the projection area of ​​the third limiting protrusion 11 along the axial direction of the connecting shaft 6 is located within the area surrounded by the first mark 8. When the connecting shaft 6 and the polymer rod 1 are assembled together, as long as the third limiting protrusion 11 is ensured to be located within the area surrounded by the first mark 8, the relative position angle of the connecting shaft 6 and the polymer rod 1 is considered to be correct.

[0057] In this embodiment, the first mark 8 is a raised portion or a recessed portion formed on the end face of the polymer rod 1. Specifically, a recessed structure or a raised structure can be processed at a position corresponding to the first mark 8 on the processing mold of the polymer rod 1. The modification of the processing mold of the polymer rod 1 is small and the improvement cost is low.

[0058] On the other hand, an embodiment of the utility model further provides an air conditioner, comprising the polymer rod device provided in any of the above embodiments. The ability of the polymer rod device provided in the above embodiments to transmit torque is improved, and it has strong reliability and low failure rate. Therefore, the air conditioner provided in this embodiment has the advantages of strong reliability, long service life and low failure rate. The derivation process of the beneficial effects of the air conditioner in the embodiment of the utility model is generally similar to the derivation process of the beneficial effects of the above polymer rod device, so it will not be repeated here.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
