[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the utility model are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.

[0030] As shown in Figures 1-7 A transmission and clutch mechanism, comprising:

[0031] An output shaft 101, and an output cavity 102 is arranged at the end of the output shaft 101, and the output cavity 102 is provided with a communicating output notch 103;

[0032] A transmission shaft 200, and the end of the transmission shaft 200 towards the output shaft 101 extends into the output cavity 102; the transmission shaft 200 is axially fixed with the output shaft 101, and the transmission shaft 200 and the output shaft 101 can rotate relative to each other in the radial direction, and the end of the transmission shaft 200 towards the output shaft 101 is provided with a transmission cavity 201, and the transmission cavity 201 is provided with a communicating transmission notch 202;

[0033] A transmission torsional spring 205, and the transmission torsional spring 205 is located in the transmission cavity 201 and is in an energy storage state, and the two pins of the transmission torsional spring 205 extend out of the transmission cavity 201 and the output cavity 102;

[0034] Among them, under normal circumstances, the transmission torsional spring 205 drives the output shaft 101 and the transmission shaft 200 to make the two at a preset angle, and the output shaft 101 rotates at the same time through the transmission torsional spring 205 to drive the transmission shaft 200 to rotate synchronously;

[0035] When the transmission shaft 200 is affected by external force and cannot rotate, the output shaft 101 can rotate relative to the transmission shaft 200 and form an angle difference on the basis of the preset angle, and the output shaft 101 drives the transmission torsional spring 205 to further store energy at the same time.

[0036] It is worth mentioning that the output shaft 101 is drivingly connected with the driving element 100.

[0037] In the embodiment, the power between the output shaft 101 and the transmission shaft 200 needs to be transmitted through the transmission torsional spring 205, so when the air outlet adjusting part 300 encounters resistance, the transmission torsional spring 205 can be elastically deformed to absorb the rotating output force of the output shaft 101, so as to avoid that the driving element 100 forcibly rotates the air outlet adjusting part 300, which can effectively prevent the finger from being pinched and other accidents from occurring, and can also avoid that the motor is damaged due to forced rotation. In addition, the elastic recovery ability of the transmission torsional spring 205 in the energy storage state enables the mechanism to automatically reset and return to the normal working state after the external resistance is removed; and the flexible connection mode of the transmission torsional spring 205 can effectively reduce the impact and vibration in the transmission process, so that the air outlet adjusting part 300 rotates more stably and the operation noise is reduced.

[0038] The existence of the output cavity 102 and the transmission cavity 201 provides the necessary internal space for installing and adjusting the transmission torsional spring 205, so that the assembler can more easily put the torsional spring into the correct position, ensure the accurate alignment between the output shaft 101 and the transmission shaft 200, and thus simplify the assembly process between the two key components; at the same time, the design of the output cavity 102 and the transmission cavity 201 also supports the modular assembly mode, and different components can be manufactured separately and then assembled.

[0039] Specifically, along the rotating direction of the output shaft 101, the output notch 103 includes the first output wall 104 and the second output wall 105, and in the rotating process of the output shaft 101, the first output wall 104 or the second output wall 105 exerts force on one of the pins of the transmission torsional spring 205.

[0041] Further preferably, the transmission cavity 201 is provided with a mounting column 206, and the transmission torsional spring 205 is sleeved on the mounting column 206.

[0042] In the embodiment, the mounting column 206 can provide accurate positioning for the installation of the transmission torsional spring 205, so as to ensure that the installation position is accurate; at the same time, the existence of the mounting column 206 can also effectively fix the transmission torsional spring 205, prevent it from shaking or shifting during transmission, and improve the stability and reliability of the transmission system.

[0044] Further preferably, during the normal rotation of the transmission shaft 200, the first output wall 104 and the first transmission wall 203 are located in the same plane direction, and the second output wall 105 and the second transmission wall 204 are located in the same plane direction; and the two pins of the transmission torsion spring 205 are respectively in contact with the corresponding first output wall 105 and the second output wall 105.

[0045] In this embodiment, when the output shaft 101 rotates, the first output wall 104 thereon can directly and effectively push one pin of the transmission torsion spring 205, which will then press on the second transmission wall 204 of the transmission shaft 200, thereby driving the transmission shaft 200 to rotate together; similarly, the second output wall 105 can act on the other pin of the transmission torsion spring 205 and transmit the force to the first transmission wall 203 of the transmission shaft 200 through it, further ensuring the effective transmission of the power.

[0046] Further preferably, one end face of the transmission shaft 200 is provided with an abutting convex ring 207, which is in contact with the cavity wall of the output cavity 102, reducing the contact area between the transmission shaft 200 and the output shaft 101, and further reducing the friction loss therebetween when the transmission shaft 200 and the output shaft 101 rotate relatively.

[0051] In the embodiment, the inclined guide surface 107 on the limiting convex block can guide the transmission shaft 200 to be smoothly inserted into the output cavity 102, reduce wear during assembly, and prolong the service life of the parts; the inclined guide surface 107 on the limiting ring 208 facilitates guiding the transmission shaft 200 to be separated when the transmission shaft 200 and the output shaft 101 are overhauled.
