Description

A kind of drive unit

Technical field

The utility model relates to a kind of drive unit, relates in particular to a kind of drive unit.

Background technology

Traditional drive unit is a mechanical type driving apparatus, its principle is when opening the door, the conversion of motion of door leaf is that the gear of drive unit inside rotates, gear rotates and drives piston linear motion compresses spring, the storage of realization energy is unclamped behind the door, and spring promotes piston motion, the piston driven gear rotates, and realizes the closing motion of door.The several shortcomings clearly of this structure, need bigger thrust when pushing the door open exactly, door is met people or object through regular meeting when closing, especially child old man, the drive unit speed of closing the door needs very big thrust meeting even the situation that occurs pushing away not open when opening the door, if can bump against health comparatively fast the time when entering; When also having more people or long object to pass through, can be very inconvenient; Have along with fire-fighting, security protection intelligent systematic development again, need the real-time status of opposite house to monitor, common drive unit can not be dissolved in this system.Along with electrified development, on the basis of mechanical type driving apparatus, electric driving device has appearred, control the work of motor by circuit, but have the analysis of electric driving device transmission mechanism now, there is following shortcoming in this structure: when different occasions are installed, need to change direction: because after the door closer installation, the direction of opening the door of left and right door can cause the direction of rotation difference of door closer output shaft, so need to change the direction of rotation of motor, causes the client that inconvenience is installed.The output shaft direction: the output shaft of present electrodynamic type structure be folk prescription to output, when left and right door is installed, the installation dimension difference.And output shaft stretches out door closer in a direction and decorates case, so not only causes installation constant, and influences the attractive in appearance of product and transportation.Reducing gear: present electrodynamic type door closer slows down and once slows down for spur gear, and this structural volume is big, and in order to reduce the pinion size, the axle of pinion is thinner, causes bending easily.

Summary of the invention

In order to address the above problem, it is little, easy for installation that the purpose of this utility model provides a kind of volume, can conveniently be used for the drive unit of left and right door simultaneously.

To achieve the above object, the utility model is mainly solved by following technical proposals: a kind of drive unit, the control device that comprises motor and control motor, described motor links to each other with reduction box a, and reduction box a is fixed in the housing, and the output shaft of reduction box a is connected synchronously with bevel gear a, bevel gear a and bevel gear b engagement, bevel gear b is connected synchronously with axle a, and any end of axle a is connected with the connecting rod of door, and described axle a is installed in the housing by bearing a.

As preferably, be connected with helical gear a synchronously on the above-mentioned axle, helical gear a and helical gear b engagement, helical gear b is connected with a b synchronously, the end of axle b is located in the shell by bearing b and lining, the other end is provided with light barrier, described housing is provided with several grooved optoelectronic switches that links to each other with control device, light barrier is realized shading and printing opacity are opened in grooved photoelectricity pass, shading is a high level, printing opacity is a low level, and described grooved photoswitch is respectively the opening position optoelectronic switch, a long position optoelectronic switch that stops, the position optoelectronic switch of closing the door, close the door the deceleration optoelectronic switch and the deceleration optoelectronic switch that opens the door.

As preferably, an above-mentioned axle a is provided with pad a and back-up ring a, and packing ring a and back-up ring a are in the two ends of bearing a.

As preferably, the two ends of above-mentioned axle a are the thread form structure.

As preferably, an above-mentioned axle b is provided with pad b and back-up ring b, and pad b and back-up ring b are in the two ends of bearing b.

Owing to after the utility model once slows down by reduction box a,, overcome prior art because the bulky defective of once slowing down again by the secondary speed-reducing of bevel gear; Any end of axle a can be connected with the connecting rod of door, and axle a is installed in the housing by bearing a, the utility model can forward and reverse any one to installation, do not need to change the direction of rotation of motor, and as long as on fixing position, can install, when having reached easy for installation, brought convenience also for packing and transportation.

The specific embodiment

Below in conjunction with accompanying drawing 1-7, the specific embodiment of the technical solution of the utility model is described in further detail.

Embodiment: a kind of drive unit comprises motor 1 and the control device of controlling motor 1.Described motor 1 links to each other with reduction box a2, and reduction box a2 is fixed on the housing 3, and the output shaft 22 of reduction box a2 is connected synchronously with bevel gear a7.Output shaft 22 supports by bearing 6, and bearing 6 is fixed in the housing 3.Above-mentioned bevel gear a7 and bevel gear b14 engagement, bevel gear b14 is connected synchronously with axle a10.In the prior art, axle a10 is connected with the side's of the being connected to tenon and the square hole of door, this kind structure be connected to matched in clearance, an idle running angle is arranged between the side's of causing tenon and the push and pull system, install and to install smoothly behind 4 the direction aiming axis a10 of connecting rod upper and lower, left and right because square tenon and square hole are connected, exist inconvenience is installed, in order to overcome above-mentioned defective, the two ends of axle a10 are designed to the thread form structure, increase the installation position of axle a10, reached effect easy for installation.Any end of axle a10 can be connected with the connecting rod of door, can not need to change the direction of rotation of motor, is convenient to use on left and right door arbitrarily.Above-mentioned axle a10 is installed on the housing 3 by bearing a11.Moving for the string that prevents an a10 and bearing a11, on axle a10, be provided with pad a8 and back-up ring a12, packing ring a8 and back-up ring a12 are in the two ends of bearing a11.
