Detailed Description

The embodiment of the utility model provides an anti-falling type mechatronic laser range finder, which comprises a shell 1, and a transmitting lens 2 and a receiving lens 3 which are arranged on the shell 1, as shown in figures 1-4.

A microchip laser, a photoelectric detector, a signal processing module and a power supply are arranged in the shell, and the photoelectric detector is used for receiving laser signals received by the lens 3 and converting the laser signals into electric signals. The photoelectric detector is in signal connection with the signal processing module, the transmitting lens 2 transmits laser generated by the microchip laser, and the power supply is used for supplying power.

When the object lands on the ground, the first contact with the ground is basically the corner of the shell 1. All be provided with on each edges and corners of casing 1 and prevent falling the subassembly for buffering when casing 1 contacts ground. The anti-falling component comprises a buffer plate 4, an inserting block 5 and an elastic plate 7, wherein the buffer plate 4 is arc-shaped. Dovetail 6 has been seted up along its length direction on each edges and corners of casing 1, buffer board 4 sets up on inserted block 5 and is located outside dovetail 6, inserted block 5 slides the adaptation at the front end of dovetail 6 along the length direction of dovetail 6 front end, the afterbody of dovetail 6 is right angle symmetry, elastic plate 7 is the U type, elastic plate 7 holding is contradicted respectively at two right angle inslot at dovetail 6 afterbody at dovetail 6 and both ends in dovetail 6, the inner of inserted block 5 is corresponding with elastic plate 7's middle part.

When the buffer board 4 contacts the ground, the inserting block 5 displaces inwards to extrude the elastic board 7, and the elastic board 7 bends to disperse pressure to two sides of the shell 1, so that stress can be effectively buffered.

Because the position probability of falling to the ground is the edges and corners of casing 1, sets up buffer board 4 outside each edges and corners of

casing

1, 4 atress of buffer board inwards extrude elastic plate 7 when falling to the ground, and the crooked buffering of elastic plate 7 can prevent effectively that casing 1 and inside electronic components from receiving the damage.

Limiting grooves 8 are formed in the two sides of the front end of the dovetail groove 6 along the length direction of the front end of the dovetail groove, spring grooves 9 are formed in the two ends of the inserting block 5, trapezoidal blocks 10 are matched with the spring grooves 9, the trapezoidal blocks 10 are connected with the bottoms of the spring grooves 9 through springs 11, and the trapezoidal blocks 10 can slide and be matched in the limiting grooves 8 along the length direction of the limiting grooves 8. The trapezoid blocks 10 are in a right-angled trapezoid shape, the tips of the trapezoid blocks 10 face the inside of the dovetail grooves 6, and the right-angled ends face outwards.

During early installation, when the insert block 5 is inserted into the dovetail groove 6, the tip end of the trapezoidal block 10 is extruded into the spring groove 9, and after the insert block 5 slides into the dovetail groove 6, the trapezoidal block 10 extends out of the spring groove 9 and is matched in the limiting groove 8 in a sliding manner. Because the right-angled end of the trapezoidal block 10 is pressed against the limiting groove 8 outwards, the plug block 5 cannot be separated from the dovetail groove 6.
