Description

Technical Field

[0001] The utility model relates to the field of automobile air conditioners, and more specifically, to an automobile air conditioner blower impeller. Background Art

[0002] Automobile air conditioner is used to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment to the best state, provide a comfortable riding environment for passengers, reduce travel fatigue, create good working conditions for drivers, and play an important role in ensuring safe driving. The air conditioner blower impeller is responsible for delivering cold air or hot air into the car, and transporting the indoor hot air or cold air to the outside through the pipeline to achieve the effect of cooling or heating. The blower is mainly composed of a motor and an impeller. When working, the motor drives the impeller to rotate at a high speed, and then realizes the air delivery work. During long-term use, a large amount of dust will adhere to the surface of the impeller, affecting the use effect. Therefore, the impeller needs to be cleaned regularly. The existing blower impeller and the motor power shaft are connected by threads, which makes it necessary to remove the entire blower when cleaning the impeller, which is extremely inconvenient, and foreign matter will enter the motor during cleaning, affecting subsequent use. In addition, the impeller blades are fixed, which leads to a small gap between two adjacent blades, making it impossible to clean the gap, resulting in incomplete cleaning. Utility Model Content

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 3 As shown, an automobile air-conditioning blower impeller includes a motor 1, a lower connecting plate 2, an upper connecting ring 3 and blades 4. A power shaft 6 is installed at the output end of the motor 1. The lower connecting plate 2 is placed at the output end of the motor 1. Lower fixing grooves 201 are evenly opened on the surface of the lower connecting plate 2. Ear plates A202 are symmetrically arranged on both sides of the outer side of the lower connecting plate 2. Columns 203 are vertically arranged on the upper surface of the ear plates A202. The upper connecting ring 3 is placed above the lower connecting plate 2. Ear plates B302 are symmetrically arranged on both sides of the upper connecting ring 3. The ear plates B302 slide on the surface of the column 203 so that the upper connecting ring 3 can be fixed along the surface of the column 203, and then the distance between the upper connecting ring 3 and the lower connecting plate 2 is adjusted. Upper fixing grooves 301 are evenly opened on the surface of the connecting ring 3, and the blades 4 are evenly distributed between the lower connecting plate 2 and the upper connecting ring 3. The top of the blade 4 is fixed on the inner side of the upper fixing groove 301, and the bottom of the blade 4 is fixed inside the lower fixing groove 201. A locking nut 303 is screwed on the surface of the column 203, and the locking nut 303 is placed above the ear plate B302. The upper connecting ring 3 is controlled to approach the lower connecting plate 2 through the locking nut 303, and then the blade 4 can be fixed through the upper fixing groove 301 and the lower fixing groove 201, and it is ensured that the blade 4 is in a tilted state and remains stable. On the contrary, the blade 4 can be disassembled during cleaning so that it can be cleaned separately to ensure the cleaning quality.

[0025] Please refer to Figure 2 and Figure 4As shown, a connection cover 5 is provided at the center of the upper surface of the lower connection plate 2, the connection cover 5 is conical, and the connection cover 5 is placed between the plurality of blades 4. A fixing bolt 9 is provided at the top of the connection cover 5, and a square hole 91 is provided at the bottom of the fixing bolt 9. A square rod 7 is provided at the top of the power shaft 6, and the square rod 7 is adapted to the inner size of the square hole 91. Through the cooperation of the two, the motor 1 is used to control the rotation of the impeller as a whole to prevent slipping.

[0026] Among them, the surface of the square rod 7 is symmetrically provided with a limiting groove 8, the inner wall of the square hole 91 is symmetrically provided with a receiving hole 10, and a wedge block 11 is slidably installed inside the receiving hole 10. The end of the wedge block 11 is adapted to the inner size of the limiting groove 8. Through the connected cooperation, the square rod 7 is inserted into the square hole 91 to be regulated, otherwise the impeller and the motor 1 will fall off.

[0027] Please refer to Figure 2 and Figure 4 As shown, a spring 12 is arranged inside the storage hole 10, and one end of the spring 12 is in contact with the end surface of the wedge block 11 facing away from the square rod 7. The elastic force of the spring 12 can effectively limit the square rod 7 when it fully enters the square hole 91, and the end of the wedge block 11 is tilted downward to achieve automatic limiting fixation.

[0028] Among them, a control sleeve 14 is slidably installed on the surface of the fixing bolt 9, and the ends of the two wedge blocks 11 that are away from each other are connected to pull ropes 13. The two pull ropes 13 both pass through the fixing bolt 9, and the ends of the pull ropes 13 that are away from the wedge blocks 11 are connected to the inner wall of the control sleeve 14. When disassembly is required, the control sleeve 14 can be slid downward to pull the wedge blocks 11 on both sides at the same time, thereby realizing the separation of the impeller and the motor 1.

[0029] Working principle: Due to the existence of the springs 12 on both sides, the wedge block 11 is always outwardly directed. At this time, the pull ropes 13 on both sides are in a taut state. The pull control sleeve 14 is pulled to be placed above the surface of the fixing bolt 9. During installation, the end of the square rod 7 can be inserted into the square hole 91. The wedge block 11 cooperates with the limit groove 8 to ensure the stability of the installation of the fixing bolt 9 and the power shaft 6. At this time, the start of the motor 1 can drive the lower connecting plate 2 to rotate. Conversely, during disassembly, the external sliding control sleeve 14 can be lowered to pull the pull rope 13 at the same time, thereby making the wedge blocks 1 on both sides 1 shrinks toward the inside of the storage hole 10 and no longer cooperates with the limiting groove 8. At this time, the lower connecting plate 2 can be separated from the motor 1 for cleaning. At the same time, the locking nuts 303 can be removed respectively to separate the upper connecting ring 3 and the column 203. At this time, the top of the blade 4 cannot be limited, and then the multiple blades 4 can be separated to facilitate fine processing. Conversely, during installation, the locking nut 303 can be screwed on so that the upper connecting ring 3 squeezes the blade 4, so that the blade 4 is effectively fixed to ensure the stability of the blade 4 when the impeller rotates.

[0030] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
