Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, specifically to a mode drive mechanism for automotive air conditioning. Background Technology

[0002] Chinese patent CN218257639U discloses a car air conditioning vent mode adjustment mechanism and a car air conditioning system. The technical solution adopted is that the driving component can drive the mode dial to rotate, and the face blowing damper assembly, foot blowing damper assembly, and defrost damper assembly are respectively movably installed in the first guide groove, second guide groove, and third guide groove on the mode dial. When the driving component drives the mode dial to rotate, the face blowing damper assembly, foot blowing damper assembly, and defrost damper assembly have a total of seven consecutive working positions, corresponding to seven sequential air outlet modes. When the face blowing defrost mode and the face blowing and foot blowing defrost mode are activated, the defrost damper will not be completely closed, ensuring that the air outlet on the face reaches its maximum while the defrost vent can simultaneously defog, resulting in high comfort, a relatively simple structure, and low cost.

[0003] The above technical solution can adjust the opening degree of the air vent through the drive mode turntable, but it still has the following shortcomings: in order to open and close multiple air vents, each air vent needs to be driven by a rocker arm with a different structure, which requires separate development of rocker arms with different structures, increasing production costs. Utility Model Content

[0005] To achieve the above objectives, this utility model discloses a mode drive mechanism for automotive air conditioning. The technical solution includes a housing and a bracket, the bracket being mounted on the housing, and the housing having an air vent and a damper at the air vent. A mode slide is rotatably connected to the facing surfaces of the housing and the bracket, and a lever is connected to the damper to drive its rotation. The housing and the bracket are rotatably connected to the connecting rods corresponding to the positions of the air dampers. The connecting rods are driven by the mode slide. An anti-misoperation mechanism is also provided between the lever and the connecting rods. Sliding pins are provided on the blowing air damper connecting rod and the defrosting air damper connecting rod to rotatably connect the mode slide to the housing, so that the sliding pins slide in the double grooves of the mode slide. The two trajectory lines do not interfere with each other, and the diameter of the mode slide trajectory line is minimized, thereby reducing the weight of the mode slide and reducing development costs.

The blowing damper lever and the defrosting damper lever adopt the same design structure, saving the development of a set of molds, thereby reducing the production and processing costs.

[0009] As a preferred technical solution of this utility model, the lever and the connecting rod are driven by teeth. The lever and the connecting rod use the principle of tooth meshing to drive the damper structure and increase the precision of the damper opening and closing.

[0010] As a preferred technical solution of this utility model, the error prevention mechanism includes a protruding tooth and a tooth groove. The connecting rod is provided with the protruding tooth, and the lever is provided with a tooth groove that meshes with the protruding tooth.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this utility model achieves the driving of the damper structure by using the meshing principle between the lever and the connecting rod, thereby increasing the degree of precise control of the opening and closing of the damper; the blowing damper lever and the defrosting damper lever adopt the same design structure, saving the development of a set of molds, thereby reducing the production and processing costs.

[0013] Sliding pins are installed on the blowing damper linkage and the defrosting damper linkage to rotate the mode slide plate to the housing, so that the sliding pins slide in the double grooves of the mode slide plate. The two trajectory lines do not interfere with each other, and the diameter of the mode slide plate trajectory line is minimized, thereby reducing the weight of the mode slide plate and reducing development costs.

Example

[0017] like Figures 1 to 5 As shown, this utility model discloses a mode drive mechanism for automotive air conditioning. The technical solution adopted includes a housing 1 and a bracket 2. The bracket 2 is installed on the housing 1, and the housing 1 has an air vent and an air damper at the air vent. The air vents include defrosting air vents, face air vents, and foot air vents, and the air dampers include defrosting air damper 4, face air damper 5, and foot air damper 6.

[0018] The housing 1 and the bracket 2 are rotatably connected to a mode slide 3 on their opposing surfaces; the left and right sides of the mode slide 3 are respectively provided with a double groove 32 and a single groove 31; the defrost damper connecting rod 8 and the face blowing damper connecting rod 10 are provided with sliding pins 13 that are adapted to the double groove 32; the foot blowing damper connecting rod 12 is provided with sliding pins 13 that are adapted to the single groove 31.

[0019] The mode slide 3 rotates, causing the sliding pins 13 that cooperate with it in the single groove 31 and double groove 32 to slide, thereby driving the blowing air damper linkage 10, the defrosting air damper linkage 8, and the foot blowing air damper linkage 12 to rotate.

[0020] The blowing air damper linkage 10 and the defrosting air damper linkage 8, which cooperate with the double groove 32 on the mode slide 3, are installed on the housing 1. The mode slide 3 drives the blowing air damper linkage 10 and the defrosting air damper linkage 8 to rotate on the housing 1, thereby driving the blowing air damper lever 9 and the defrosting air damper lever 7 to rotate.

The foot blowing damper connecting rod 12 and the mode slide 3 are provided with a sliding pin 13 that cooperates with the single groove 31. The mode slide 3 drives the foot blowing damper linkage 12 to rotate around the hinge point with the bracket 2. Since the foot blowing damper lever 11 is fixedly connected to the foot blowing damper 6, it drives the foot blowing damper 6 to rotate, thereby controlling the opening degree of the foot blowing damper 6.

[0022] The damper is connected to a lever that drives it to rotate. The defrost damper 4, the face blowing damper 5, and the foot blowing damper 6 are respectively connected to a defrost damper lever 7, a face blowing damper lever 9, and a foot blowing damper lever 11. The housing 1 and the bracket 2 are rotatably connected to a connecting rod corresponding to the position of the damper, and the connecting rod is driven by the mode slide 3.

[0023] The housing 1 is rotatably connected to a defrost damper link 8 and a face blowing damper link 10, which correspond to the positions of the defrost damper lever 7 and the face blowing damper lever 9, and the bracket 2 is rotatably connected to a foot blowing damper link 12, which corresponds to the position of the foot blowing damper lever 11.

[0024] The defrosting damper lever 7 and the blowing damper lever 9 have the same structure.
