[0024] Please refer to Figures 1-3 This embodiment provides a drive linkage mechanism 100, which includes a connecting seat 110, a connecting rod 120, and a snap-fit ​​member 130. The connecting seat 110 is used to connect with the air conditioning unit 210; the connecting rod 120 is rotatably connected to the connecting seat 110 and is used to drive the damper shaft 220. The snap-fit ​​130 is connected to the connecting seat 110 or the connecting rod 120, and the snap-fit ​​130 is used to engage with the connecting rod 120 or the connecting seat 110 to restrict the movement of the connecting rod 120 along its rotation axis.

[0025] Please refer to Figures 1-3 The working principle of the drive linkage mechanism 100 is as follows: The drive linkage mechanism 100 includes a connecting seat 110, a connecting rod 120, and a snap-fit ​​element 130. The connecting seat 110 is used to connect to the air conditioning unit 210. The connecting rod 120 is rotatably connected to the connecting seat 110 and is used for transmission connection with the damper shaft 220. The snap-fit ​​element 130 is connected to the connecting seat 110 or the connecting rod 120, and is used to engage with the connecting rod 120 or the connecting seat 110 to restrict the movement of the connecting rod 120 along its rotation axis. This drive linkage mechanism 100 is applied to an air conditioning unit. When assembling the connecting rod 120, the snap-fit ​​element 130 in this structure allows the connecting rod 120 and the connecting seat 110 to be assembled by engaging with the snap-fit ​​element 130. This reduces the number of parts required during the installation of the connecting rod 120 and improves the assembly efficiency of the connecting rod 120, thereby reducing parts costs and assembly costs.

[0026] It should be noted that when configuring the connecting seat 110, it can be integrally formed with the air conditioning unit body 210 of the air conditioning unit, or it can be assembled and connected with the air conditioning unit body 210 of the air conditioning unit. In this embodiment, the example of the connecting seat 110 being integrally formed with the air conditioning unit body 210 of the air conditioning unit is used for explanation. Furthermore, when drivingly connecting the connecting rod 120 and the damper shaft 220, the connecting rod 120 and the damper shaft 220 can be directly connected, or a transmission rod 230 can be added. In this embodiment, the connecting rod 120 and the damper shaft 220 are drivenly connected by setting the transmission rod 230.

[0027] Furthermore, when configuring the card connector 130, it can be disposed on the connector 110 or on the connecting rod 120. In this embodiment, please refer to... Figures 1-4The method adopted is to set the snap-fit ​​130 on the connecting seat 110. Specifically, the snap-fit ​​130 is connected to the connecting seat 110; the connecting rod 120 is provided with a rotating connecting part 121, a snap-fit ​​part 122 and a transmission connecting part 123. The rotating connection part 121 is rotatably connected to the connecting seat 110, the engaging part 122 is used to engage with the engaging member 130, and the transmission connection part 123 is used to drive the damper shaft 220. The rotating connection part 121 and the transmission connection part 123 are arranged at intervals.

[0028] Therefore, through the above-described structural arrangement, the rotating connecting part 121 can be rotatably connected to the connecting seat 110, and after the rotatable connection is in place, the locking member 130 can engage with the locking part 122 on the connecting rod 120. The engagement of the locking member 130 with the locking part 122 can restrict the movement of the connecting rod 120 along its rotation axis, thereby preventing the connecting rod 120 from disengaging from the connecting seat 110. Moreover, this arrangement can improve assembly efficiency through the engagement of the locking member 130.

[0029] In order to enable the snap-fit ​​part 130 to be quickly assembled with the snap-fit ​​part 122, the snap-fit ​​part 122 includes a snap-fit ​​groove 124 and the rotating connection part 121 includes a through hole 125 formed at the bottom of the snap-fit ​​groove 124.

[0030] Please refer to Figures 1-5 The connecting seat 110 includes a seat body 111 and a shaft 112 connected to the seat body 111; the shaft 112 is rotatably engaged with the through hole 125; the snap-fit ​​member 130 includes a snap-fit ​​block 131 disposed at one end of the shaft 112 away from the seat body 111, the snap-fit ​​block 131 being used to engage with the snap-fit ​​groove 124.

[0031] Therefore, when assembling the connecting rod 120, the end of the shaft 112 with the locking block 131 can be passed through the through hole 125, so that the through hole 125 and the shaft 112 can be rotated together until the locking piece 130 engages with the locking groove 124. In this way, the connecting rod 120 can be fixed in a limited position while rotating and installing it, thereby improving its assembly efficiency.

[0032] It should be noted that when configuring the card block 131, the card block 131 and the connector 110 can be made as a single unit.

[0033] Furthermore, it should be noted that since the through hole 125 is located at the bottom of the slot 124, and the locking block 131 engages with the slot 124, and since the function of the locking member 130 is to restrict the movement of the connecting rod 120 along its rotation axis, the engagement of the locking block 131 with the slot 124 will not affect the rotational fit between the through hole 125 and the shaft 112. Alternatively, it can be understood that the frictional resistance between the locking block 131 and the bottom surface of the slot 124 can be ignored.

[0034] During the rotation of the connecting rod 120 relative to the shaft 112, since the locking block 131 is connected to the shaft 112, in order to avoid the locking block 131 getting stuck in the locking groove 124, the locking groove 124 is a circular groove and coaxial with the through hole 125. This allows the locking block 131 and the locking groove 124 to rotate relative to each other during the rotation of the connecting rod 120 relative to the shaft 112, so as to avoid jamming.

[0035] Based on the above structure, in order to improve the stability of the connecting rod 120 and the connecting seat 110, the snap-fit ​​component 130 includes multiple snap-fit ​​blocks 131, which are spaced apart around the axis of the shaft body 112.

[0036] Since the locking block 131 is connected to the shaft 112, and the locking block 131 needs to undergo a certain deformation when it passes through the through hole 125 and moves to the position where it engages with the slot 124, the shaft 112 is hollowed out so that the locking block 131 can deform toward the center of the shaft 112, thereby improving the assembly efficiency and reducing the assembly difficulty.

[0037] To reduce the impact of foreign objects entering the shaft 112 on the rotational fit between the shaft 112 and the through hole 125, the drive linkage mechanism 100 also includes a pressure cap. The pressure cap is detachably connected to the shaft 112 and is used to abut against the connecting rod 120 to seal the shaft 112. To simplify the installation of the pressure cap, a portion of the pressure cap can extend into the hollow part of the shaft 112 and engage or abut against the interior of the shaft 112, thereby preventing foreign objects from entering.

[0038] To improve the strength of the connecting rod 120, a reinforcing rib 140 is provided on the connecting rod 120.

[0039] Based on the above, please refer to Figures 1-5 This embodiment also provides an air conditioning unit, which includes an air conditioning unit body 210, a driving component, and the aforementioned driving linkage mechanism 100; The connecting seat 110 and the driving component are both connected to the air conditioning unit 210, and the connecting rod 120 is connected to the damper shaft 220 connected to the air conditioning unit 210 in a driving connection; the driving component is connected to the connecting rod 120 in a driving connection.

[0040] During use, the air conditioning unit drives the linkage 120 to move through the action of the drive component, thereby driving the damper shaft 220 to move and adjust the opening of the damper. Moreover, since it adopts the aforementioned drive linkage mechanism 100, it has all the advantages of the aforementioned drive linkage mechanism 100, so it will not be described in detail here.

[0041] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
