[0027] Refer to Figures 1 to 8, in an embodiment of the present invention, an automotive air-conditioning logic disk drive structure includes a support plate 11 fixedly connected to an air-conditioning housing. On both sides of the support plate 11, a drive disk 12 and a logic disk 13 are respectively provided. The drive disk 12 and the logic disk 13 are connected by at least two sets of bushing assemblies 14 penetrating through the support plate 11. On one side of the drive disk 12, there is a positioning cover 15 connected to the support plate 11. The drive disk 12 is rotatably connected to the positioning cover 15. A soft wire 16 for driving the rotation of the drive disk 12 is sleeved on the drive disk 12. The support plate 11 is provided with a drive hole 111 for the bushing assembly 14 to rotate relative to the support plate 11. In the middle of the side of the logic disk 13 close to the support plate 11, there is a positioning shaft 131. The support plate 11 is provided with a positioning bushing 112 adapted to the positioning shaft 131. The positioning shaft 131 and the positioning bushing 112 are rotatably inserted and connected.

[0028] In the automotive air-conditioning logic disk drive structure according to an embodiment of the present invention, the logic disk 13 is positioned and connected to the support plate 11 by inserting the positioning shaft 131 into the positioning bushing 112, reducing the probability of the logic disk 13 tilting up and down during movement and improving the working precision of the logic disk 13. At the same time, it avoids the problem of uneven friction force when the logic disk 13 is positioned by screws and the tightness of the screws cannot be kept consistent, effectively ensuring that the driving torque received by the logic disk 13 is consistent and improving the product quality stability. At the same time, by setting at least two sets of bushing assemblies 14, the drive disk 12 can drive the logic disk 13 with at least a double-force arm, making the rotation of the logic disk 13 more stable, and further making the air door control precision higher, more stable and reliable, greatly reducing the failure rate of the air door coming out and getting stuck.

[0029] The positioning shaft 131 is provided with a receiving groove 1311. The positioning bushing 112 is provided with a bushing boss 1121 adapted to the receiving groove 1311. When the positioning shaft 131 is inserted into the positioning bushing 112, the bushing boss 1121 is inserted into the receiving groove 1311 to form a double positioning. The receiving groove 1311 is provided with a positioning table 1312. The positioning table 1312 is provided with a positioning groove 1313. The bushing boss 1121 is provided with a bushing stud 1122 adapted to the positioning groove 1313. When the positioning shaft 131 is inserted into the positioning bushing 112, the bushing stud 1122 is also inserted into the positioning groove 1313 to form a third positioning of the positioning shaft 131 and the positioning bushing 112, effectively ensuring the stable connection between the positioning shaft 131 and the positioning bushing 112 and reducing the probability of the logic disk 13 tilting during rotation. In this embodiment, the receiving groove 1311 penetrates the positioning shaft 131 and the logic disk 13, and the positioning groove 1313 penetrates the positioning table 1312.

[0030] The bushing assembly 14 includes a drive shaft 141 provided on the side wall of the drive disk 12 and a drive bushing 142 provided on the side wall of the logic disk 13. The drive shaft 141 and the drive bushing 142 are inserted into each other. The connecting lines of each drive shaft 141 and the center of the drive disk 12 form bisecting lines that equally divide the drive disk 12. The insertion of the drive shaft 141 and the drive bushing 142 can connect the drive disk 12 and the logic disk 13, so that when the drive disk 12 rotates, it drives the logic disk 13 to rotate. The position where the drive shaft 141 is located can ensure that the force arm formed by the drive disk 12 on the logic disk 13 transmits a stable torque. In this embodiment, there are two sets of bushing assemblies 14. The two drive shafts 141 are located on the diameter of the drive disk 12, and the two drive bushings 142 are located on the diameter of the logic disk 13. There are two drive holes 111 provided on the support plate 11. The drive holes 111 are arc-shaped and are used for the drive shaft 141 or the drive bushing 142 to penetrate. In this embodiment, the drive bushing 142 penetrates the drive hole 111.

[0031] Several clamping plates 151 are provided at the side end of the positioning cover 15, and several convex plates 113 corresponding to the clamping plates 151 are provided on the side wall of the support plate 11. The clamping plates 151 and the convex plates 113 are snap-connected. Through the connection between the clamping plates 151 and the convex plates 113, the positioning cover 15 and the support plate 11 are detachably connected. In this embodiment, an opening is provided in the middle of the clamping plate 151, and a protrusion adapted to the opening is provided on the convex plate 113, so that the clamping plate 151 and the convex plate 113 are snap-connected. Moreover, except for the connection between the clamping plate 151 of the positioning cover 15 and the convex plate 113 on the support plate 11, the rest of the positioning cover 15 maintains a gap with the support plate 11, which is convenient for the drive disk 12 to be placed between the support plate 11 and the positioning cover 15. In this embodiment, there are three clamping plates 151, which are evenly distributed at the side end of the positioning cover 15, and correspondingly, there are also three convex plates 113.

[0032] A positioning shaft 121 is provided in the middle of the side of the drive disk 12 close to the positioning cover 15, and a positioning hole 152 adapted to the positioning shaft 121 is provided in the middle of the positioning cover 15. The positioning shaft 121 penetrates the positioning hole 152 and is rotatably connected to it. Several convex blocks 122 are provided at the side end of the positioning shaft 121. The convex blocks 122 abut against the edge of the positioning hole 152. There is a gap between the drive disk 12 and the support plate 11. The setting of the convex blocks 122 makes the positioning shaft 121 stuck in the positioning hole 152, so that the drive disk 12 is positioned. The fact that the drive disk 12 does not abut against the support plate 11 can reduce the friction force of the drive disk 12 when it rotates. In this embodiment, an extension ring is provided at the edge of the positioning hole 152, and the convex blocks 122 abut against the edge of the extension ring. The positioning shaft 121 can be hidden by the length of the extension ring and the thickness of the positioning cover 15. In this embodiment, there are three convex blocks 122 in total, which are evenly distributed on the side wall of the positioning shaft 121.

[0033] The edge of the drive disk 12 is provided with a transmission groove 123 adapted thereto. The soft wire 16 is embedded in the transmission groove 123, and the other end of the soft wire 16 is connected to the automotive air-conditioning knob assembly; the positioning cover 15 is provided with a positioning block for positioning the soft wire 16. In this embodiment, the principle that the automotive air-conditioning button assembly cooperates with the soft wire 16 and the transmission groove 123 cooperates with the soft wire 16 to drive the rotation of the disk where the transmission groove 123 is located is well known to those skilled in the art, so it will not be described in detail herein. In this embodiment, the disk is the drive disk 12.

[0034] A plurality of track grooves 132 are provided on the side wall of the logic disk 13 adjacent to the support plate 11. A plurality of transmission components 17 rotatably connected thereto are provided on the support plate 11. One end of the transmission component 17 is embedded in the track groove 132, and the other end is connected to the air door. The transmission component 17 includes a first transmission block 171 and a second transmission block 173 both rotatably connected to the support plate 11. One end of the first transmission block 171 is provided with a first transmission plug 172 adapted to the track groove 132. One end of the second transmission block 173 is provided with a second transmission plug 174 fixedly connected to the air door. The other end of the first transmission block 171 and the other end of the second transmission block 173 are connected by meshing with set teeth. The meshing connection between the first transmission block 171 and the second transmission block 173 can improve the rotation accuracy of the air door. In this embodiment, the first transmission plug 172 is embedded in the track groove 132 and drives the rotation of the second transmission block 173 as the logic disk 13 rotates. The second transmission plug 174 on the second transmission block 173 is connected to the air door, thereby driving the rotation of the air door, adjusting the position of the air door, and achieving the purpose of adjusting the cold and warm air output and the mode of the air conditioner. In this embodiment, there are three track grooves 132 and three groups of transmission components 17. Connecting columns are provided on one side of both the first transmission block 171 and the second transmission block 173. The connecting columns penetrate through the support plate 11 and can rotate relative to the support plate 11, and the two ends of the connecting columns are thick and the middle is thin, so that the connecting columns can be stuck on the support plate 11.
