Detailed Description
The embodiments of the present invention will be described with reference to the accompanying drawings and preferred embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure in the specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are for purposes of illustration only and are not intended to limit the scope of the present invention.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic concept of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the form, amount and ratio of the components in actual implementation may be changed at will, and the layout of the components may be more complicated.
This embodiment has proposed a large-scale trailer, as shown in fig. 2, including main car 1 and trailer 2, install first rear-view mirror 3 and second rear-view mirror 4 respectively in the both sides of main car 1, both are connected with main car 1 through the pivot of motor, and when the motor started, can drive the pivot and rotate, and then drive first rear-view mirror 3 or the certain angle of second rear-view mirror 4 upset.
A first pull rope displacement sensor and a second pull rope displacement sensor are arranged between a main vehicle 1 and a trailer 2, the first pull rope displacement sensor and the second pull rope displacement sensor are both arranged on the main vehicle 1, the first pull rope displacement sensor is provided with a first pull rope 6, the second pull rope displacement sensor is provided with a second pull rope 7, the end part of the first pull rope 6 and the end part of the second pull rope 7 are both connected with the trailer 2, when the main vehicle 1 does not turn or does not turn, the main vehicle 1 and the trailer 2 are superposed, the first pull rope 6 and the second pull rope 7 are parallel, the extending amounts of the first pull rope and the second pull rope are the same, and at the moment, the first pull rope 6 and the second pull rope 7 are in an initial state.
When the host vehicle 1 turns in the manner shown in fig. 2, the first rope 6 is extended as compared to the initial state, and the second rope 7 is retracted as compared to the initial state, so that the amount of extension of the first rope 6 is larger than the amount of extension of the second rope 7, and the larger the angle between the host vehicle 1 and the trailer 2, the larger the difference between the amount of extension of the first rope 6 and the amount of extension of the second rope 7.
Still set up the controller in this embodiment, first stay cord displacement sensor and second stay cord displacement sensor's inside all is equipped with on a screwed wheel hub, this wheel hub links together with a precision rotation inductor, and first stay cord 6 or second stay cord 7 then twine on wheel hub, when first stay cord 6 and second stay cord 7 stretch out or retract back, can drive the wheel hub rotation that corresponds, and then precision rotation inductor can be according to wheel hub's rotatory degree, the volume of stretching out of the stay cord that will correspond turns into electric signal output.
After receiving the electric signals output by the first pull rope displacement sensor and the second pull rope displacement sensor, the controller outputs corresponding electric signals according to the difference value of the extension amounts of the first pull rope displacement sensor and the second pull rope displacement sensor, sends the electric signals to the motor connected with the second rearview mirror 4, controls the rotating shaft of the motor to rotate at a certain angle, drives the second rearview mirror 4 to turn over until a driver can observe the road surface condition at the rear part of the trailer 2 through the second rearview mirror 4, and can eliminate the sight blind area 5.
The relationship between the turning angle of the second rearview mirror 4 and the extension amounts of the first and second pull ropes 6 and 7 may be different depending on the sizes of the main and trailer vehicles 1 and 2, or may be changed depending on the stature and driving habits of the driver, and the setting of the specific relationship between the angle and the extension amount is available to those skilled in the art without creative work based on the above-described structure.
In this embodiment, the controller integrates a minimum threshold, and when the difference between the extension amount of the first cord 6 and the extension amount of the second cord 7 is less than or equal to the minimum threshold, the motor may not be driven to rotate. That is to say, the locomotive changes the direction and forms less angle and the scope that does not influence driver's sight with the carriage, though the stay cord contracts and extends certain distance but the motor does not move, rear-view mirror angle is unchangeable, and the size of minimum threshold value also can be according to different motorcycle types, different statures and the driving custom of driver and actual road conditions needs artificial settlement.
In this embodiment, the specific relationship between the turning angle of the second mirror 4 and the extending amounts of the first cable 6 and the second cable 7 is shown in fig. 3, and for clarity, the rotation of the rotating shaft of the motor for turning the second mirror 4 is converted into the swing of the rotating shaft.
As shown in fig. 3, in the initial state, the rotation axis of the motor is parallel to the Y direction, and when the main vehicle 1 turns, the angle between the perpendicular line from the end of the second rope 7 to the first rope 6 and the Y direction is a, which should be equal to the angle of the swing of the rotation axis of the motor, so that the following relationship can be obtained:
wherein: a is the swinging angle of the rotating shaft of the motor, which is equal to the rotating angle of the motor;
L 3 the vertical distance between the end part of the second pull rope and the first pull rope;
Δ L is a difference in the amounts of extension of the first cord 6 and the second cord 7.
When the turning is completed and the host car 1 and the trailer 2 are overlapped in the X direction, the second rearview mirror 4 is gradually returned to the initial state.
When the main car 1 turns in the opposite direction to that of fig. 2, the first rearview mirror 3 is turned in the same manner as the second rearview mirror 4, and the description thereof is omitted.
When initial condition, expose first stay cord 6 and the second stay cord 7 outside and all overlap and be equipped with the bellows lag to first stay cord 6 is the example, and when first stay cord 6 elongates, the bellows lag extends, otherwise, then the bellows lag shortens, avoids freezing winter or the sensitivity that the adhesion foreign matter influences stay cord displacement sensor.
The above embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model.
