[0039] The utility model provides a transmission structure, including transmission part 100 and cooperation piece 110, wherein:

[0040] The cooperation piece 110 and transmission part 100 are provided with anti -jam structure, and the anti -jam structure at least partial structure is provided on the rotation path of transmission part 100, to make transmission part 100 and cooperation piece 110 transmission connection;

[0041] And, the anti -jam structure can produce elastic deformation when the torsion between cooperation piece 110 and transmission part 100 exceeds preset value, to make transmission part 100 and cooperation piece 110 relative rotation.

[0042] The utility model provides a transmission structure, including transmission part 100 and cooperation piece 110, the cooperation piece 110 and transmission part 100 are provided with anti -jam structure, and the anti -jam structure at least partial structure is provided on the rotation path of transmission part 100, to make transmission part 100 and cooperation piece 110 transmission connection, namely when transmission part 100 rotates, cooperation piece 110 can follow rotation under the driving of transmission part 100, to reach the effect of power transmission, and the anti -jam structure can produce elastic deformation when the torsion between cooperation piece 110 and transmission part 100 exceeds preset value, to make transmission part 100 and cooperation piece 110 relative rotation, thereby through anti -jam structure can realize power transmission of transmission part 100 and cooperation piece 110, and can realize in the situation that cooperation piece 110 is jammed, transmission part 100 continues to rotate and does not influence driving structure or cross-flow fan blade, effectively protects cross-flow fan blade and drive assembly, simultaneously, anti -jam structure produces elastic deformation, and transmission part 100 continues to rotate and will contact anti -jam structure and send out sound, to reach the purpose of realizing abnormal detection quickly, can be convenient for and timely find rotation anomaly.

[0043] Need to explain is, the anti -jam structure is arranged between cooperation piece 110 and transmission part 100, and transmission part 100 can drive cooperation piece 110 to rotate through anti -jam structure, and when the torsion between transmission part 100 and cooperation piece 110 is too big, due to the elastic deformation of anti -jam structure, this makes the torsion between transmission part 100 and cooperation piece 110 can make transmission part 100 overcome the block of anti -jam structure, continues to rotate, avoids the problem that driving structure or cross-flow fan blade is easily damaged due to rigid transmission between transmission part 100 and cooperation piece 110.

[0044] In some embodiments of the utility model, the anti - jam structure is the transmission of the piece 120 which is annular array setting in the cooperation piece 110, the free end of transmission of the piece 120 is set on the rotation path of transmission piece 100.

[0045] In some embodiments of the utility model, the anti - jam structure is the transmission of the piece 120, the transmission of the piece 120 annular array setting is on the inner wall of cooperation piece 110, the free end of transmission of the piece 120 is set on the rotation path of transmission piece 100, the transmission of the piece 120 can limit the rotation of transmission piece 100, and when the torsion between transmission piece 100 and cooperation piece 110 exceeds the preset value, transmission piece 100 can drive the deformation of transmission of the piece 120, so that transmission piece 100 continues to rotate under the drive of drive structure, so as to realize the flexible connection between transmission piece 100 and cooperation piece 110, and solve the problem that rigid connection of transmission piece 100 and cooperation piece 110 can cause damage to drive structure or cross-flow fan blade.

[0046] It can be understood that the primary task of the transmission of the piece 120 is to have sufficient strength, and the transmission of the piece 120 as an important component in the structure needs to bear certain external force, only with strong strength, can normally operate under various complex working conditions, and does not deform or damage. This requires strict control on the selection of aluminum alloy, preferably using high-quality aluminum alloy material to ensure that the internal organizational structure is compact and uniform, thereby providing a solid strength basis for the piece.

[0047] Secondly, the toughness of the transmission of the piece 120 cannot be ignored. The toughness is a key performance that the transmission of the piece 120 can absorb energy by deformation when bearing external force impact, to avoid brittle fracture. To ensure the toughness of the transmission of the piece 120, the casting process needs to accurately control the casting temperature, cooling speed and other parameters, and optimize the microstructure of the aluminum alloy, so that it has high strength and good toughness.

[0048] Furthermore, the transmission of the piece 120 needs to be able to produce a push when the torque exceeds the specified value. This feature is crucial, when the drive structure (motor) encounters abnormal load during operation, causing the torque to exceed the specified value, the transmission of the piece 120 can respond in time and produce a push action. This push can make the motor shaft rotate normally in the middle position, effectively avoiding the motor from stalling, stopping and other faults due to excessive torque, and ensuring the stable operation of the motor.

[0049] In some embodiments of the utility model, the transmission of the piece 120 is an arc structure, and the convex direction of the transmission of the piece 120 is opposite to the rotation direction of the transmission piece 100.

[0050] In some embodiments of the utility model, the transmission piece 120 is arc structure, the convex direction of transmission piece 120 is opposite with the rotation direction of transmission member 100, so that the free end of transmission piece 120 is towards transmission member 100, only when the torsion of transmission member 100 and cooperating member 110 exceeds the preset value, transmission member 100 and cooperating member 110 relatively rotate, ensure the transmission effect between transmission member 100 and cooperating member 110, ensure the transmission reliability of driving structure and cross-flow fan blade.

[0051] Preferably, the radian angle of transmission piece 120 is 45 degrees.

[0055] It can be understood that the positioning ring 130 is connected with the cooperating member 110, and the anti-blocking convex 140 protrudes from the inner wall of the positioning ring 130, so that the transmission member 100 arranged on the inner side of the positioning ring 130 can ensure good transmission connection effect between the transmission member 100 and the cooperating member 110 under the limiting action of the anti-blocking convex 140 when rotating, and secondly, the anti-blocking convex 140 can elastically deform when the torsion between the cooperating member 110 and the transmission member 100 exceeds the preset value, so that the transmission member 100 and the cooperating member 110 relatively rotate, thereby ensuring that the driving structure and the cross-flow fan blade will not be damaged when the cooperating member 110 abnormally rotates.

[0056] It should be noted that the anti-stuck protrusion 140 needs to have a certain elastic deformation amount to ensure that the power transmission of the transmission member 100 and the matching member 110 can be realized, and when the torsion is large, the transmission member 100 can rotate alone; the positioning ring 130 can be made of plastic, or can be made of rubber, and the specific preparation material can be selected according to actual needs, so that the positioning ring 130 can be connected with the matching member 110.

[0057] Specifically, the positioning ring 130 and the matching member 110 can be connected by a quick release structure, for example, a trapezoidal positioning groove is arranged on the positioning ring 130, and a trapezoidal positioning protrusion is arranged on the inner wall of the matching member 110, the positioning protrusion and the positioning groove are matched, thereby realizing detachable connection.

[0060] In some embodiments of the utility model, the anti-stuck protrusion 140 is provided with a beveled structure 150, the direction of the line connecting the first end of the beveled structure 150 that is closer to the positioning ring 130 and the second end of the beveled structure 150 that is farther away from the positioning ring 130 is consistent with the rotation direction of the transmission member 100, and the transmission member 100 can rotate along the direction of the beveled structure 150, so that when the torsion between the transmission member 100 and the matching member 110 is too large, the beveled structure 150 is quickly passed, ensuring that the transmission member 100 continues to rotate, effectively protecting the driving structure and the cross-flow fan blade.

[0061] In some embodiments of the utility model, the cross section of the transmission member 100 is a regular polygon structure.

[0062] In some embodiments of the utility model, the cross section of the transmission member 100 is a regular polygon structure, when the transmission member 100 rotates, the rotation track formed is a circle, the anti-blocking structure is arranged at least partially on the rotation path of the transmission member 100, when the cross section of the transmission member 100 is a regular polygon structure, the anti-blocking structure can abut against the edge of the transmission member 100, and the transmission effect between the transmission member 100 and the cooperating member 110 can be ensured.
