Embodiment Construction

[0020] The multifunctional gear of the present invention and the knob transmission assembly using it will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0021] exist Figure 1 to Figure 4 Shown in is a schematic diagram of the multifunctional gear 10 in an embodiment of the present invention. The multifunctional gear 10 mainly includes a wheel 2 , a gear 4 fixed on the wheel and a gear shaft 1 extending from the bottom of the wheel 2 . When the gear shaft 1 rotates, it will drive the wheel disc 2 and the gear 4 to rotate.

[0022] The gear 4 includes at least two face gears fixed on the upper surface of the wheel disc 2, and three face gears 41, 42, 43 are used in this embodiment. The face gears 41, 42, 43 and the gear shaft 1 are coaxially arranged, so the rotation angle of the gear shaft 1 is consistent with the rotation angle of the face gears 41, 42, 43, and the face gears 41, 42 can be accurately controlled by ...

Abstract

The invention relates to a multifunctional gear and a rotary knob transmission assembly applying the multifunctional gear. The rotary knob transmission assembly comprises a first-level gear (11), a second-level gear (20), a rotary knob cover cap and a spring bead (6), wherein the first-level gear is the multifunctional gear (10) and comprises a gear disc (2), a gear body (4) fixed to the gear disc, and a gear shaft (1). The gear body fixed to the gear disc comprises at least two face gears of different toothed structures, and a cylindrical gear (3) arranged between the gear disc and the gear shaft. The rotary knob cover cap is connected with the gear shaft in a separable mode. The second-level gear and the cylindrical gear are meshed so as to transmit rotation of the rotary knob cover cap. The spring bead fixed to a rear cover abuts against one tooth portion of one face gear so as compress a spring. When the spring bead abuts against gear teeth of the face gears of the different toothed structures, the face gears of the different toothed structures can generate different resistances and different torques when rotating to pass through the spring bead, and therefore one gear structure can control different functions.

Description

technical field [0001] The invention relates to a gear and a gear transmission assembly, in particular to a multifunctional gear and a knob transmission assembly using the same. Background technique [0002] At present, with the development of the machinery industry, the demand for gears is increasing. Through transmission with other toothed mechanical parts, the gear can realize functions such as changing the speed and torque, changing the direction of motion, and changing the form of motion. Existing automotive air-conditioning controllers have functions such as wind speed regulation, temperature regulation, and wind direction regulation. Usually, the gear structures for controlling the knob gears of different functions are different. When assembling automotive air-conditioning controllers, different molds are required to produce gears with different structures, and the cost is high. When assembling, it is necessary to pay attention to the assembly position of gears wit...
