The lower section of machine, the shell is interior to be provided with diode above first gear.
The utility model, which is further arranged on the screw rod, is provided with reset spring, and the both ends of the reset spring are set respectively
It is equipped with screw rod set and buffer stopper, the buffer stopper is sleeved on the screw rod, the screw rod set is coaxially disposed with second gear.
The utility model, which is further arranged in the shell, is formed with motor cavity, gear cavity and diode placing chamber, institute
It states motor to be arranged in motor cavity, the first gear and second gear are arranged in gear cavity, on the diode placing chamber
It is provided with column, is connected between the diode and column by conducting wire.
It is pinion gear that the first gear, which is further arranged, in the utility model, and the second gear is gear wheel, i.e., described
The radius of addendum of gear wheel is greater than the radius of addendum of first gear.
The modulus that the second gear is further arranged in the utility model is set as 0.7.
The utility model, which is further arranged the first gear and is all made of stainless steel with second gear, to be made.
It is pressure spring that the reset spring, which is further arranged, in the utility model.
The utility model has the following beneficial effects: changing the modulus of second gear, increase the modulus of second gear using mould
Number is the gears of m=0.7, so that the intensity of second gear improves, is driven and is not easy stuck, mold is more easy to manufacture；Furthermore increase by two poles
Pipe is connected with motor, is eliminated inverse electromotive force, is kept gear return more smooth.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 be in Fig. 1 N to observing resulting partial schematic diagram.
Specific embodiment
The utility model is described further below in conjunction with attached drawing.
As shown in Figs. 1-2, the utility model uses such a tailgate latch, including shell 1, sets in the shell 1
