Specific embodiments

[0027] Please refer to Figures 1-6 for further description of the embodiments of the present utility model;

[0028] As Figures 1-3 shown, an assembly component of an air conditioner stepping motor includes a bottom frame 1. Installation spaces 3 and air ducts are arranged on the front side of the bottom frame 1 in a left-right distribution. A progressive motor 18 is installed in the installation space 3, and several swing blades 2 are installed in the air duct;

[0029] An inclined assembly port 4 is arranged in the installation space 3. A quick-release plate 5 is arranged in the assembly port 4. The middle and left sides of the quick-release plate 5 are both threadedly connected to the bottom frame 1, and the right side of the quick-release plate 5 is clamped to the bottom frame 1. A through hole 6 is arranged in the middle of the quick-release plate 5. The progressive motor 18 is installed on the rear side of the quick-release plate 5. A rotating shaft 8 is fixed to the output end of the progressive motor 18. A crank 7 is rotatably connected to the end of the rotating shaft 8. The crank 7 is hinged to the quick-release plate 5, and the end of the crank 7 is rotatably connected to a connecting rod 9. The right end of the connecting rod 9 is in transmission connection with the swing blade 2; During installation, the worker can first fix the progressive motor 18 on the rear side of the quick-release plate 5, then connect the rotating shaft 8 and the crank 7, then pass the rotating shaft 8 and the crank 7 through the through hole 6 together, then fix the progressive motor 18 on the rear side of the quick-release plate 5, then place the quick-release plate 5 together with the progressive motor 18 in the installation space 3 from front to back, and then make the middle and left sides of the quick-release plate 5 both threadedly connected to the bottom frame 1, and the right side of the quick-release plate 5 is clamped to the bottom frame 1. A hinge part is arranged on the front side of the quick-release plate 5. Then, the lower end of the crank 7 is installed on the hinge part to form a rotation, and the upper end of the crank 7 is installed on the left end of the connecting rod 9 to form a hinge, which can significantly improve the installation efficiency of the worker. When the progressive motor 18 works, it drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the crank 7, and the crank 7 drives the connecting rod 9 to rotate, thereby driving the swing blade 2 to swing left and right to change the air direction of the air conditioner. The technical principle is based on the prior art.

[0030] As Figure 3As shown, in order to facilitate the production of the quick-release plate 5, a threaded connection structure (such as a connecting column) is not used at the lower right corner of the quick-release plate 5, because it is difficult to demold there. Instead, a simple clip-on structure is used to connect it to the bottom frame 1, which makes demolding more convenient and facilitates standardized production, thereby improving the standardization of the structure to ensure quality control; the middle and left parts of the quick-release plate 5 are connected to the bottom frame 1 by threaded connections, thereby improving the overall stability.

[0031] The three-point assembly (the left side, the middle and the right side of the quick release plate 5) greatly improves the stability of the quick release plate 5 after assembly, and the rotation drive of the entire structure is also very stable.

[0032] A surrounding plate 12 located below the through hole 6 is integrally formed on the rear side of the quick-release plate 5, and a support plate 11 flipped up toward the through hole 6 is fixed on the surrounding plate 12, and the progressive motor 18 is fixed on the support plate 11. The end of the rotating shaft 8 passes through the front side of the support plate 11 and is rotatably connected to the crank 7. A pin is provided on the support plate 11, and the crank 7 is provided with a pin hole matching the pin. The pin hole and the pin are matched to realize hinged connection and rotation; the support plate 11 is used to support and fix the progressive motor 18. The surrounding plate 12 is provided to enhance the connection strength between the support plate 11 and the quick-release plate 5, and it is also convenient for workers to install the progressive motor 18 and the crank 7 on the support plate 11. Through the above-mentioned arrangement, the connection of the crank 7 is faster and more stable, and the rotation drive effect is better.

[0033] The through hole 6 is a special-shaped hole, and the through hole 6 matches the crank 7. Through such an arrangement, when the stepper motor 18 is installed on the quick-release plate 5, the rotating shaft 8 on the stepper motor 18 together with the crank 7 can quickly pass through the special-shaped hole from the rear side of the quick-release plate 5 to the front side of the quick-release plate 5, thereby improving the installation efficiency of the workers.

[0034] A driving hole 10 communicating with the installation space 3 is opened on the left front side of the bottom frame 1. The right end of the connecting rod 9 passes through the driving hole 10 and extends into the air duct. A plurality of avoidance grooves 17 are opened on the rear side of the installation space 3. The setting of the driving hole 10 facilitates the insertion of the connecting rod 9 into the installation space 3 and the air duct. The avoidance groove 17 on the rear side of the installation space 3 is used to avoid the key parts of the stepper motor 18. Because the stepper motor 18 is assembled from the rear side to the front side, this can expand the margin of the entire installation space of the stepper motor 18, prevent interference and abutment during the assembly process, and thus improve the assembly efficiency.

[0035] The threaded connection between the quick release plate 5 and the middle and left sides of the assembly opening 4 (bottom frame 1) is specifically configured as follows: a first front sleeve block 14 is integrally formed in the middle of the front side of the quick release plate 5, and an L-shaped plate 28 extending and bent in the vertical direction is integrally formed on the left side of the quick release plate 5, and a second front sleeve block 15 is integrally formed on the bent surface of the L-shaped plate 28; there are two fixing columns 27 on the assembly opening 4, which are respectively nested with the first front sleeve block 14 and the second front sleeve block 15 and then threadedly connected.

[0036] A side plate 16 is integrally formed around the perimeter of the front side of the quick-release plate 5. The left end of the surrounding plate 12 slopes upward and is integrally formed with the vertical plate surface of the L-shaped plate 28, and the right end of the surrounding plate 12 slopes upward and is integrally formed with the side plate 16. Through such a setting, while improving the strength of the surrounding plate 12, the two inclined surfaces on the left and right of the surrounding plate 12 can also play a role in restricting the rotation stroke of the crank 7, ensuring that the rotation of the crank 7 is more stable.

[0037] The quick-release plate 5 is snap-connected to the right side of the assembly port 4 (bottom frame 1) with the following specific settings: a convex block 21 protruding downward is provided at the lower right corner of the assembly port 4, and a hook 20 matching the convex block 21 is provided at the lower right corner of the quick-release plate 5.

[0038] A pair of assembly ears 19 are fixed to the side walls of the stepping motor 18. Two connecting columns 25 matching the assembly ears 19 are provided on the diagonal line at the rear side of the quick-release plate 5. The hook 20 is located between the two connecting columns 25, and triangular claws 26 are provided around the two connecting columns 25. Through such a setting, first, the assembly ears 19 on both sides of the stepping motor 18 are snapped into the triangular claws 26, thus ensuring the coaxial alignment of the assembly ears 19 and the connecting columns 25. Then, two bolts are used to tighten and fix them, improving the assembly efficiency of workers and making the structure more stable.

[0039] A reinforcing rib 24 is fixed to the rear side of the quick-release plate 5 between the hook 20 and the connecting column 25 at the upper left corner of the rear side. Through such a setting, when the hook 20 is pressed and deformed under force to buckle the convex block, it can improve the overall strength of the quick-release plate and prevent the quick-release plate 5 from being damaged.

[0040] A wire passing hole 13 is formed in the quick-release plate 5. A lapping plate 23 that is vertically matched with the wire passing hole 13 is integrally formed on the left side of the assembly port 4. The lapping plate 23 has an avoidance opening 22, and the avoidance opening 22 corresponds to the wiring terminal seat of the stepping motor 18 in space. Through such a setting, when the entire quick-release plate 5 together with the stepping motor 18 is placed into the installation space 4 from front to back, the sharp corner of the terminal seat of the stepping motor 18 can pass through the avoidance opening 22 without interference, realizing the stable installation of the stepping motor 18 and improving the installation efficiency of workers.
