Furthermore, the reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic may be included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Examples

Referring to fig. 1 to 6, the present embodiment provides a laser radar environment detection system, including a radar 100 and an adjustment assembly 200, where the radar 100 is disposed on the adjustment assembly 200, and the adjustment assembly 200 is used to adjust a pitch angle of the radar.

Specifically, the adjusting assembly 200 includes a fixed seat 201 and a rotating member 202 hinged to the fixed seat 201, and the radar 100 is fixedly mounted on the rotating member 202. The fixing base 201 serves as a base for supporting, and the rotating member 202 can rotate relative to the fixing base 201.

Wherein, the both sides of fixing base 201 one end all are provided with articulated seat 203, and articulated seat 203 is provided with mounting hole 203a, rotates piece 202 including rotating a section of thick bamboo 202a, and in the tip embedding mounting hole 203a of rotating a section of thick bamboo 202a, it can use to rotate a section of thick bamboo 202a as the centre of a circle rotation to rotate a piece 202, and then adjusts the angle of radar.

Further, a first end face ratchet 204 is fixedly installed in the installation hole 203a, one end of the rotating cylinder 202a, which is located in the installation hole 203a, is connected with a second end face ratchet 205, the first end face ratchet 204 is connected with the second end face ratchet 205 in a matched manner, and the axial direction of the second end face ratchet 205 is not fixed, it should be noted that the second end face ratchet 205 can rotate relative to the first end face ratchet 204, and due to the transmission principle of the ratchet, the first end face ratchet 204 can prevent the second end face ratchet 205 from rotating reversely; when the radar 100 wants to return to the horizontal position, the first end ratchet 204 limits the rotation of the rotation member 202.

Further, the rotating cylinder 202a is provided with a connecting rod 206, the connecting rod 206 is located in the rotating cylinder 202a and can move along the axial direction of the rotating cylinder 202a, the connecting rod 206 is fixedly connected with the second end face ratchet wheel 205, the connecting rod 206 is provided with a limiting boss 206a, the rotating cylinder 202a is provided with a limiting groove 202b, and the limiting boss 206a is embedded in the limiting groove 202b, so that the connecting rod 206 cannot rotate relative to the rotating cylinder 202a, that is, the second end face ratchet wheel 205 cannot rotate relative to the rotating cylinder 202 a. In this embodiment, the described pitch angle is an included angle between the upper surface of the radar and the horizontal plane, and when the included angle is increased from 0 °, the ratchet teeth of the second end surface ratchet wheel 205 directly pass over the ratchet teeth of the first end surface ratchet wheel 204 in the process of rotating the radar; when the angle is rotated to 0 °, the ratchet teeth of the first end ratchet 204 will limit the ratchet teeth of the second end ratchet 205 to pass over, so as to form a snap fit, and therefore, in order to reset the radar, the second end ratchet 205 needs to be disengaged from the first end ratchet 204.

Specifically, the rotating member 202 further includes an adjusting cylinder 202c connected to the rotating cylinder 202a and perpendicular to the axis of the rotating cylinder 202a, that is, the adjusting cylinder 202c and the rotating cylinder 202a form a "T" shaped structure, and both the adjusting cylinder 202c and the rotating cylinder 202a are hollow inside.

The part of the adjusting cylinder 202c connected with the rotating cylinder 202a forms a sliding groove 202d extending along the axial direction of the adjusting cylinder 202c, a sliding block 207 is arranged in the sliding groove 202d, and the sliding block 207 can move along the axial direction of the adjusting cylinder 202c in the sliding groove 202 d; the side of the sliding block 207 is provided with a groove 207a, and the tail end of the connecting rod 206 extends into the groove 207 a; wherein, the side of the groove 207a is provided with an inclined groove 207b, the end of the connecting rod 206 is provided with a projection 206b along the radial direction, and the projection 206b is embedded in the inclined groove 207 b.

Further, the chute 207b includes a first end 207c and a second end 207d, the first end 207c is close to the end of the adjusting cylinder 202c and is inclined in a direction away from the axis of the adjusting cylinder 202c, and the second end 207d is far from the end of the adjusting cylinder 202c and is inclined in a direction away from the axis of the adjusting cylinder 202 c. Therefore, when the slider 207 moves toward the adjustment cylinder 202c, the inclined groove 207b can move toward the axial center of the adjustment cylinder 202c with the protrusion 206b, i.e., the connecting rod 206, even though the second end ratchet 205 is disengaged from the first end ratchet 204.

Preferably, a first spring 301 is disposed between the second end ratchet 205 and the rotary barrel 202a, and the elastic force of the first spring 301 makes the second end ratchet 205 contact with the first end ratchet 204. Therefore, when the pitch angle of the radar is increased, it is necessary to overcome the elastic force of the first spring 301, and when the radar returns, it is necessary to separate the two ratchets against the elastic force of the first spring 301.

Further, a transmission rod 208 is arranged in the adjusting cylinder 202c, the transmission rod 208 is fixedly connected with the slider 207, one end, away from the slider 207, of the adjusting cylinder 202c is connected with an adjusting piece 209, the adjusting piece 209 is provided with a through hole 209a, the transmission rod 208 penetrates through the through hole 209a, a circular truncated cone 208a extending in the radial direction is arranged on the transmission rod 208, a spiral groove 209b is arranged in the through hole 209a, and the circular truncated cone 208a is embedded into the spiral groove 209 b; therefore, when the adjusting piece 209 is rotated, the transmission rod 208 can be moved along the axial direction, and the adjusting piece 209 is used for adjustment, so that the phenomenon that the transmission rod 208 is touched by mistake when being adjusted directly is avoided.

Preferably, the adjusting cylinder 202c is provided with an annular plate 202e, the adjusting member 209 is provided with an annular groove 209c at the periphery, the annular plate 202e is clamped in the annular groove 209c to limit the axial movement of the adjusting member 209, and the second spring 302 is arranged between the adjusting member 209 and the sliding block 207. The elastic force of the second spring 302 causes the projection 206b to be initially located at the first end 207 c.

Still further, in order to prevent the misoperation of the adjusting part 209, the end of the adjusting cylinder 202c extends axially to form a protective shell 202f, a rotating part 400 is arranged in the protective shell 202f, the protective shell 202f is provided with a pressing hole 202g, one end of the rotating part 400 is sleeved outside the adjusting part 209, the other end of the rotating part 400 extends out of the pressing hole 202g, and a limiting protrusion 401 is further arranged on the rotating part 400 to prevent the rotating part 400 from falling off. First clamping grooves 402 which are evenly distributed are formed in the circumferential direction of one end, close to the adjusting part 209, of the rotating part 400, a second clamping groove 209d which can be meshed with the first clamping groove 402 is formed in one end of the adjusting part 209, and a third spring 303 is arranged between the adjusting part 209 and the rotating part 400. When first draw-in groove 402 and second draw-in groove 209d contact, the rotating member 400 just can drive adjusting part 209 and rotate, when first draw-in groove 402 and second draw-in groove 209d separate, no matter how rotating member 400 rotates, can not influence adjusting part 209, consequently needs the elasticity of third spring 303 to separate adjusting part 209 and rotating member 400 under initial condition.

It should be noted that the adjustment assembly 200 is a symmetrical structure as a whole.

In this embodiment, in the initial state, the radar is integrally stored, that is, the pitch angle is 0 ° at this time, and the radar body can be directly lifted up to be inclined; when the pitch angle needs to be stored or reduced again, the rotating piece 400 is pressed down to be in contact with the adjusting piece 209 and then rotates again, so that the second end face ratchet wheel 205 can be separated from the first end face ratchet wheel 204 through transmission between parts, and then the pitch angle is directly reduced. The pitching angle of the radar is adjusted, the process is simple, and the operation is convenient.
