Description
Technical field
The utility model relates to a kind of screw, in particular to a kind of dedicated anti-loose screw structure of pilotless automobile.
Background technique
Pilotless automobile is to perceive road environment by vehicle-mounted sensor-based system, and automatic planning travelling line simultaneously controls vehicle
Reach the intelligent automobile of predeterminated target.It is vehicle-periphery to be perceived using onboard sensor, and obtained according to perception
Road, vehicle location and obstacle information, the steering and speed of vehicle are controlled, to enable the vehicle to reliably and securely exist
It is travelled on road.Integrate numerous technologies such as automatic control, architecture, artificial intelligence, vision calculating, is computer section
It learns, the product of pattern-recognition and intelligent control technology high development, and measures a national research strength and industrial level
One important symbol has broad application prospects in national defence and national economy field.
It is unmanned to need that there is extremely big security and stability, but the screw for needing to use in automobile manufacture now is past
Toward that can loosen in vibration, institute wastes a lot of manpower and material resources safeguarded, causes the wasting of resources.
For this purpose, it is proposed that a kind of dedicated anti-loose screw structure of pilotless automobile.
Utility model content
The main purpose of the utility model is to provide a kind of dedicated anti-loose screw structure of pilotless automobile, Ke Yiyou
Effect solves the problems in background technique.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of dedicated anti-loose screw structure of pilotless automobile, including screw terminal, the screw terminal lower end are equipped with smooth
Bar portion, smooth shank portions surface upper end are equipped with anti-loose washer, and the anti-loose washer lower surface is equipped with locking ladder, described
Anti-loose washer middle-end is equipped with perforation, and the smooth shank portions surface activity is connected with compressed spring, under the smooth shank portions surface
End is connected with compression washer, and the smooth shank portions lower end is equipped with thread rod part, and the thread rod part surface is equipped with screw thread.
Further, the screw terminal, smooth shank portions and thread rod part are an integral structure.
Further, the thread rod part and screw thread are an integral structure.
Further, the smooth shank portions are connected with anti-loose washer by perforating movable, and the diameter of the perforation is less than
The diameter of screw terminal.
Further, the ladder direction of the locking ladder and screw means is contrary.
Compared with prior art, the utility model has the following beneficial effects:
1. the utility model by perforating movable by connecting smooth shank portions with anti-loose washer, and the diameter perforated
Less than the diameter of screw terminal, so that anti-loose washer is not easy to fall off after mounting, and set by anti-loose washer lower surface
The locking ladder having is not likely to produce the sign to fall off so that increasing frictional force between screw and machine；
2. the utility model passes through anti-loose washer, compressed spring and the compression washer being equipped with, and compressed spring is put
Between anti-loose washer and compression washer, make screw be constantly in tensioned state after mounting, will not be loosened because of vibration,
The problem of effective solution screw loosens；
3. the utility model structure is simple, easy to use, novel in design, fastening effect is good, and effective solution screw loosens
Phenomenon, the drawbacks of overcoming the prior art, have extensive value of industrial utilization.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the dedicated anti-loose screw structure of the utility model pilotless automobile.
Fig. 2 is the anti-loose washer structure diagram of the dedicated anti-loose screw structure of the utility model pilotless automobile.
In figure: 1, screw terminal；2, anti-loose washer；3, smooth shank portions；4, compressed spring；5, compression washer；6, threaded rod
Portion；7, screw thread；8, locking ladder；9, it perforates.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figs. 1-2, the dedicated anti-loose screw structure of a kind of pilotless automobile, including screw terminal 1, the screw terminal
1 lower end is equipped with smooth shank portions 3, and the 3 surface upper end of smooth shank portions is equipped with anti-loose washer 2, anti-loose 2 lower surface of washer
Equipped with locking ladder 8, anti-loose 2 middle-end of washer is equipped with perforation 9, and 3 surface activity of smooth shank portions is connected with compression bullet
Spring 4, the 3 surface lower end of smooth shank portions are connected with compression washer 5, and 3 lower end of smooth shank portions is equipped with thread rod part 6,
6 surface of thread rod part is equipped with screw thread 7.
Wherein, the screw terminal 1, smooth shank portions 3 and thread rod part 6 are an integral structure.
Wherein, the thread rod part 6 and screw thread 7 are an integral structure.
Wherein, the smooth shank portions 3 and anti-loose washer 2 are flexibly connected by perforation 9, and the diameter of the perforation 9 is less than
The diameter of screw terminal 1.
Wherein, the ladder direction of the locking ladder 8 and screw means is contrary.
It should be noted that the utility model is a kind of dedicated anti-loose screw structure of pilotless automobile, when work, lead to
It crosses when screw being installed into machine by screw terminal 1 using tool, by the way that smooth shank portions 3 and anti-loose washer 2 are passed through perforation 9
It is flexibly connected, and the diameter of perforation 9 is less than the diameter of screw terminal 1, so that anti-loose washer 2 is not easy to fall off after mounting,
And it is not easy by the locking ladder 8 that anti-loose 2 lower surface of washer is equipped with so that increasing frictional force between screw and machine
The sign to fall off is generated, and compressed spring 4 is put between anti-loose washer 2 and compression washer 5, makes screw after mounting
