Description

Car body collision arrangement for detecting

Technical field

The utility model about a kind of car body collision arrangement for detecting, it is espespecially a kind of the center of car body bumper bar or a left side, When colliding at right two sides with barrier, the device of crash behavior can be all detected really.

Background technique

In the place of the palpus carrying heavy goods such as farmland, factory and hospital, Chang Kejian carries out short distance article using carrier It transports, with the development of science and technology, automatic guided vehicle is developed appearance, automatic guided vehicle, for power, and is equipped with and is led with motor etc. Navigate device, collision avoidance sensor and light etc., to reach designated place along setting path automatically, complete under unmanned state Article carrying operation.

To improve automatic guided vehicle along the safety of fixed course traveling process, existing automatic guided vehicle would generally be on chassis Collision avoidance sensor is installed in the side of vehicle frame, which mainly utilizes infrared ray or ultrasonic principle of reflection, is removed with detecting Transport vehicle between barrier at a distance from, and reach anti-collision effect.However the infrared ray or supersonic collision avoidance sensor are easy because anti- It shoots angle, reflection drift to death, or occurs situations such as moving barrier or catastrophic failure suddenly, cause automatic guided vehicle in due course Avoid, and with barrier collision situation, therefore, to prevent from losing using the contactless collision avoidance sensor such as infrared ray or ultrasonic Effect, existing automatic guided vehicle can install the collision detection device of contact then at the front and back ends of chassis frame, to collide barrier After hindering object, automatic guided vehicle is made to suspend actuation.

Since the collision detection device of existing automatic guided vehicle is mainly installed in the front and back ends centre of chassis frame, therefore Only when the front and back ends centre of chassis frame is collided, which can just have an effect, however, in reality Find that automatic guided vehicle is most subjected to the position of collision at the arranged on left and right sides of front and back ends using upper, rather than in front and back ends Position is entreated, therefore is designed according to the collision detection of existing carrier, it is difficult in the left and right of automatic guided vehicle chassis frame front and back ends When two sides are collided by barrier, barrier is detected in time, it is still lasting after causing carrier to collide the barriers such as pedestrian, equipment Advance, and cause pedestrian injured or equipment, carrier damage or carrier on the danger such as carrying article collapses.

Then, the designer designs in view of its collision detection device of existing carrier is implementing still have above-mentioned lack using upper It falls into, is and through multi-party clever thought, being researched and created practical by assisting in the manufacture of related fields and design experiences and knowledge for many years It is novel.

Accordingly, it when the car bodies such as the carrier of collision detection device for being equipped with the utility model are during traveling, protects When dangerous 3 left or right side of bar collides barrier, also referring to shown in Fig. 5, now it is to collide barrier on the right side of bumper bar 3 Example explanation, the lower section of Fig. 5 are the direction of advance of carrier, at this point, being located at the touch of its roller wheel handle type of the microswitch 7 on right side Portion 71 will receive 3 right side pushing against section 32 of bumper bar, and slide one angle of offset, to trigger 7 actuation of microswitch, and The controller that signal gives carrier is issued, continues the controller and carrier is driven to suspend actuation, and issues warning message and informs management Personnel come to remove barriers, or carry out avoidance action according to its pre-set programs.

And barrier is collided on the right side of the bumper bar 3, when making bumper bar 3 turn left to deviate, it is inserted in its limiting section of bumper bar 3 Gag lever post 5 in 34 limit hole 341 can be butted on the positioning of 341 right side hole wall of rectangle limit hole, deviate width to limit bumper bar 3 Degree, and the wear plate 4 for utilizing limiting section 34 and organizing between vertical plate 2 designs, and can make limiting section 34 and group vertical plate 2 that will not rub damage It is bad, when bumper bar 3, which is turned left, to be deviated, be set to elastic component 6 between bumper bar 3 and chassis frame 1 its sleeve 12 can compressive deformation, When bumper bar 3 is detached from barrier, which can restore and push bumper bar 3 and move to right reset.

In this, is designed, can carried by the microswitch 7 that the utility model is set to 3 arranged on left and right sides of bumper bar When the arranged on left and right sides of its 1 front and back ends of chassis frame of vehicle is collided, barrier is detected really, additionally, due to the utility model Microswitch 7 using the setting of 45 degree angles, therefore, referring to Figure 6 together shown in, when 3 centre of bumper bar is collided, this It can be also toggled using the microswitch 7 that 45 degree of angles are arranged, whereby, collide barrier effectively to reach automatic guided vehicle Afterwards, stop carrier actuation in time, still persistently advance after colliding the barriers such as pedestrian, equipment to avoid carrier, cause to go People is injured or equipment, carrier damage or carrier on carrying article the situations such as collapse.

By above structure and embodiment it is found that the utility model has the advantages that

1. the car body collision arrangement for detecting of the utility model is respectively set at the arranged on left and right sides of the forward and backward bumper bar of carrier There is microswitch, whereby, when being collided at the arranged on left and right sides that its forward and backward bumper bar is most subjected to shock when automatic guided vehicle, Barrier can be detected in time and suspend carrier actuation, to avoid still lasting caused damage of advancing after barrier is encountered.

2. the car body collision arrangement for detecting of the utility model makes micro- at the arranged on left and right sides of its forward and backward bumper bar of carrier Dynamic switch is in 45 degree angles settings, and in this, no matter bumper bar arranged on left and right sides or centre are collided, and should be arranged in 45 degree of angles Microswitch can be all toggled, and effectively be detected when achieving the effect that carrier collides barrier.

3. the car body collision arrangement for detecting of the utility model is equipped with wear plate between the limiting section and group vertical plate of bumper bar, borrow The setting of this wear plate can prevent limiting section and group vertical plate friction damage situation.

4. the car body collision arrangement for detecting of the utility model makes the limiting section of bumper bar be equipped with a rectangle limit hole, and makes group Vertical plate is inserted with gag lever post at the corresponding limit hole, according to this, when bumper bar collides barrier and front and rear, left and right is displaced, It is designed by the gag lever post and limit hole, bumper bar actuation in effective range can be made, and over-deflection situation will not occur.
