Abstract
The utility model discloses an electric motor which comprises a shell, a motor, a transmission gear device and an electric motor shaft. The motor, the transmission gear device and the electric motor shaft are disposed in the shell in a sequential drive connection manner. An ejector pin parallel with the electric motor shaft is further disposed in the shell. One end, close to the gear transmission device, of the ejector pin is connected with an end sleeve seat, the middle section of the ejector pin is connected with a middle sleeve seat, and the other end of the of the ejector pin penetrates out of the shell and is connected with a top plate. The end sleeve seat and the middle sleeve seat are parallel and sleeved on the electric motor shaft. A spring is disposed and a hard needle perpendicular to the electric motor shaft is connected between the end sleeve seat and the middle sleeve seat on the electric motor shaft. One end of the spring is butted against the end sleeve seat while the other end of the spring is butted against the hard needle. By the spring, the electro motor is made idle when pulse signals are overlong to prevent burnout of the electric motor. The spring can maintain the state of the electric motor when the electric motor finishes corresponding actions. The circumstances that the motor state is changed by external interference are prevented effectively. In addition, energy consumption is effectively reduced by utilizing elastic potential energy of the spring.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to the motor of using on the electronic products such as a kind of electronic lock.
Background technology
As everyone knows, motor is necessity and the core component of the electronic product such as electronic lock, yet is applied to existing motor in the electronic product such as electronic lock motor easy burn-out, simultaneously expense electricity and anti-external interference ability in the long situation of pulse signal.
The utility model content
In view of this, technical problem to be solved in the utility model is: the safe not burning of a kind of use, energy-saving and cost-reducing, jamproof motor are provided.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of motor, wherein, comprise housing, be located at and drive successively the motor that links to each other in the described housing, transmission gear means and motor shaft, also be provided with the push rod parallel with described motor shaft in the described housing, described push rod is connected with end cover axle bed in the end near described transmission gear means, the stage casing is connected with middle part cover axle bed, the other end passes described housing and is connected with top board, described end cover axle bed is parallel with middle part cover axle bed and be socketed on the described motor shaft, described motor shaft is arranged with spring on the position between described end cover axle bed and the middle part cover axle bed, described motor shaft also is provided with and self vertical hard pin that links to each other on the position between described end cover axle bed and the middle part cover axle bed, and described spring one end is supported on the cover axle bed of described end, the other end is low to be withstood on the described hard pin.
As preferably, described motor and motor shaft transmission gear means arranged side by side, described is connected between described motor and the motor shaft in the back location place of described enclosure interior, and described top board is positioned at outside the front of described housing, and the back of described housing has bonnet.
As shown from the above technical solution, the beneficial effects of the utility model are:
Compared to existing technology, the utility model is by to setting and the utilization of spring, can allow motor dally in the long situation of pulse signal on the one hand, prevents that motor from burning out; After motor was finished corresponding actions, spring can effectively keep its state on the other hand; Can also prevent effectively that in addition external interference is to the change of motor status; The elastic potential energy of utilizing simultaneously spring is effective energy efficient also.

Embodiment
In order to make those skilled in the art can further understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing.
See also Fig. 1 to shown in Figure 2, the utility model provides a kind of motor, wherein, comprise housing 1, be located at and drive successively the motor 2 that links to each other in the described housing, transmission gear means 3 and motor shaft 4, also be provided with the push rod parallel with described motor shaft 5 in the described housing, described push rod is connected with end cover axle bed 6 in the end near described transmission gear means, the stage casing is connected with middle part cover axle bed 7, the other end passes described housing and is connected with top board 8, described end cover axle bed is parallel with middle part cover axle bed and be socketed on the described motor shaft, described motor shaft is arranged with spring 9 on the position between described end cover axle bed and the middle part cover axle bed, described motor shaft also is provided with and self vertical hard pin 10 that links to each other on the position between described end cover axle bed and the middle part cover axle bed, described spring one end is supported on the cover axle bed of described end, the other end is low to be withstood on the described hard pin, described motor and motor shaft are arranged side by side, described transmission gear means is connected between described motor and the motor shaft in the back location place of described enclosure interior, described top board is positioned at outside the front of described housing, and the back of described housing has bonnet 11.
Operation principle of the present utility model is as follows: by external circuit to direct impulse signal of motor, so that motor forward, drive by transmission gear means, so that motor shaft rotates, interleave an iron pin in the motor shaft and overlapping a spring, spring one end is supported on the cover axle bed of end, the other end is low to be withstood on the hard pin, in the utility model, hard pin is preferably the iron pin, the motor shaft rotation can make the iron pin rotate around spring, and spring can be transferred to iron pin below, and push rod will be ejected like this, in like manner, motor is received a reverse impulse signal, and spring forwards the top of iron pin to, and the motor push rod will be regained, just realized thus the function of stretching out and regaining, used as the switch that triggers to be applied in the electronic product such as electronic lock.
But the above only is better possible embodiments of the present utility model, is not to limit to claim of the present utility model, so the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, all in like manner is included in the scope of the present utility model.
