Abstract
Disclosed is a safety clutch for an overturn mechanism of a load displayer of a vehicle, comprising an electromotor fixing ring which outputs torque, and a rotary shaft fixing ring driven by the electromotor fixing ring. The utility model is characterized in that the rotary shaft fixing ring is fixed with a spring fixing ring which is provided with a plurality of spring slots loaded with springs; the electromotor fixing ring is fixedly connected with a steel ball fixing ring which is provided with a plurality of steel ball slots loaded with steel balls; the spring fixing ring is elastically connected with the steel ball fixing ring, and the springs in the spring slots prop up the steel balls in the steel ball slots. When in use, the steel ball fixing ring drives the spring fixing ring to rotate and when the resistance is bigger than the intended spring force of the springs, the steel balls slide into the spring slots, then the steel ball fixing ring begins to rotate while the spring fixing ring stops rotating.
Description
Technical field
The utility model relates to a kind of engaging and disengaging gear, the concrete safe engaging and disengaging gear that relates to a kind of vehicle-mounted demonstration upset.
Background technique
In present vehicle-mounted indication structure, transmission device drives the make displays flip-flop movement after being the direct output torque of motor, makes it reach several angle, and passenger uses in buying car in installments.If but inner occur unexpected or can cause the upset load to increase when external force is arranged, exceed the specified output torque of motor, cause burn-down of electric motor, even entire product is scrapped.
The model utility content
Technical problem to be solved in the utility model is, a kind of safe engaging and disengaging gear of vehicle-mounted demonstration upset is provided, and it can be quit work before running into infringement, guarantees the intact of its related accessory.
In order to address the above problem the technical solution of the utility model is such:
The safe engaging and disengaging gear of vehicle-mounted demonstration upset, the motor retainer ring that comprises an output torque, with the rotating shaft retainer ring that drives by the motor retainer ring, it is characterized in that, the fixedly connected spring retainer ring of described rotating shaft retainer ring, have a plurality of spring grooves on the spring retainer ring, has spring in the spring groove, the fixedly connected steel ball retainer ring of described motor retainer ring has a plurality of steel bead grooves on the steel ball retainer ring, have steel ball in the steel bead groove, the spring retainer ring is connected with steel ball retainer ring elasticity, spring in the spring groove withstands the steel ball in the steel bead groove, and under the user mode, the steel ball retainer ring drives the spring retainer ring and rotates, when rotation meets obstructions, steel ball slips in the spring groove, and the steel ball retainer ring rotates, and the spring retainer ring is motionless.
Be connected by an axial bearing pin elasticity between described steel ball retainer ring and the spring retainer ring.
Be bolted to connection between described rotating shaft retainer ring and the spring retainer ring.
Be bolted to connection between described motor retainer ring and the steel ball retainer ring.
Working principle of the present utility model is; under normal circumstances; the motor output torque; the motor retainer ring drives the steel ball retainer ring and rotates together; owing to drive by steel ball between steel ball retainer ring and the spring retainer ring; has certain frictional force; so the spring retainer ring also rotates together thereupon; the spring retainer ring is driving the rotation of rotating shaft retainer ring; thereby driving display apparatus pivot; when rotation runs into the resistance of serious offense spring setting elastic force; the motionless spring retainer ring of steel ball band steel ball can slip in the spring groove; have only motor retainer ring and steel ball retainer ring to rotate together this moment, and spring retainer ring and rotating shaft retainer ring are motionless, have effectively protected the safety of motor and Motor torque output block.
Beneficial effect, the utility model adds a safety installations between motor and output unit, guarantee under the normal condition that output torque meets the requirement of flip displays, this safety installations inside can produce skidding when running into abnormal conditions and surpass the external force of normal upset, cut off the output of motor, guarantee that other accessory does not damage.Simple in structure, install and use very convenient.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the safe engaging and disengaging gear structural representation of the vehicle-mounted demonstration upset of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the safe engaging and disengaging gear of vehicle-mounted demonstration upset, fixedly connected by bolt 10 between steel ball retainer ring 6 and the motor retainer ring 7, has steel bead groove 5 on the steel ball retainer ring 6, the steel ball 51 of in steel bead groove 5, packing into, fixedly connected by bolt 1 between spring retainer ring 4 and the rotating shaft retainer ring 2, has spring groove 3 on the spring retainer ring 4, has spring 31 in the spring groove 3, spring retainer ring 4 keeps being connected with bearing pin 9 by guide holder 7 with steel ball retainer ring 6, steel ball 51 compresses spring 31, and half is pressed into steel ball 51 in the steel ball retainer ring 6, and second half is in steel bead groove 5, by steel ball 51 steel ball retainer ring 6 and spring retainer ring 4 are connected together like this, make that elasticity is connected between spring retainer ring 4 and the steel ball retainer ring 6, but coaxial rotation, and surface of contact can slide mutually.
Under normal circumstances, when motor retainer ring 8 behind the motor input torque, rotate together and make that the rotating shaft retainer ring can output torque thereby drive the whole erection device.After running into extra resistance and surpassing the moment of torsion that erecting device sets, steel ball retainer ring 6 is gone into steel ball 51 in the spring retainer ring by force, steel ball retainer ring 6 rotates with the spring retainer ring like this, thereby the moment of torsion that the rotating shaft retainer ring place that makes obtains is not more than the moment of torsion that erecting device is set, and has guaranteed the safety of input and output and other accessory.
Compared with prior art, the utility model adds a safety installations between motor and output unit, guarantee under the normal condition that output torque meets the requirement of flip displays, this safety installations inside can produce skidding when running into abnormal conditions and surpass the external force of normal upset, cut off the output of motor, guarantee that other accessory does not damage.Simple in structure, install and use very convenient.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
