While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
Referring to fig. 1, a laser radar 100 according to an embodiment of the present invention includes a radar body 10, a laser emitting plate 20, and a laser receiving plate 30. The laser emitting plate 20 and the laser receiving plate 30 are respectively disposed on the radar body 10. The laser emitting plate 20 is used for emitting outgoing laser towards a detection target; the laser receiving board 30 is used for receiving the reflected laser light reflected by the detection target and converting the optical signal into an electrical signal, thereby analyzing the position, three-dimensional image, speed, and the like of the detection target. And the radar body 10 is connected with a power device, and the power device drives the whole radar body 10 and the laser transmitting plate 20 and the laser receiving plate 30 which are positioned on the radar body 10 to rotate, so that the detection range of the laser radar 100 is wider, and the range of 360 degrees around can be detected.
Referring to fig. 2, the radar body 10 includes a shaft center connecting portion 11 and a base 12. It can be understood that the base 12 of the radar body may also be referred to as a bottom plate of the radar body, that is, a supporting plate structure at the bottom of the radar body for bearing the laser emitting plate, the laser receiving plate, the lens holder, and other structures, and the following embodiments are not repeated. The base 12 is connected with the laser emitting plate 20 and the laser receiving plate 30, optionally, the axle center connecting portion 11 and the base 12 are integrally formed, or the axle center connecting portion 11 and the base 12 are fixedly connected, and the axle center connecting portion 11 is located at the center of the base 12 and is perpendicular to the base 12. The shaft center connecting part 11 is cylindrical, a fixing hole 111 communicated with the base 12 is formed in one end, connected with the base 12, of the shaft center connecting part, and the fixing hole 111 is used for connecting an extending shaft of the power device. Specifically, the protruding shaft extends into the fixing hole 111 from a side of the base 12 away from the axis connecting portion 11, and is in interference fit with the fixing hole 111. Compared with other connection modes such as threaded connection and the like, the connection mode does not generate bending and torsional stress on the extension shaft, has no influence on the rotation precision of the extension shaft, and simultaneously improves the concentricity of the shaft center connection part 11 and the extension shaft through interference fit, thereby ensuring the dynamic balance of the radar body 10 during rotation. When the power device is started, the extension shaft starts to rotate and drives the shaft center connecting part 11 to rotate, so that the base 12, the laser emitting plate 20 and the laser receiving plate 30 are driven to rotate together, and the laser radar 100 integrally rotates. It can be understood that the base 12 is disc-shaped, and the axial center connecting portion 11 and the base 12 are integrally formed, so that the concentricity can be improved, radial runout of the base 12 during rotation can be avoided, and the stability of the base 12 during rotation can be further improved.
It can be understood that: the connection mode of the axis connecting part 11 and the base 12 and the shape of the axis connecting part 11 and the base 12 are not limited to the above-described mode and shape, and may be other modes and shapes, and are not described herein again.
In addition, the radar body 10 further includes a lens frame 13, a connecting vertical plate 14, and a weight 15. The lens frame 13 and the connecting vertical plate 14 are respectively connected to the base 12, the lens frame 13 and the connecting vertical plate 14 are respectively located at two sides of the axis connecting portion 11, and the connecting vertical plate 14 is located on the same plane of symmetry axes of the lens frame 13 for transmitting and receiving lenses. The connecting vertical plate 14 may be integrally formed with the axis connecting portion 11 and the base 12, and optionally, the connecting vertical plate 14 may also be fixedly connected with the axis connecting portion 11 and the base 12. The other side of the connecting upright plate 14 relative to the axis connecting portion 11 is connected to a weight 15, so that the weight 15 is fixed on the edge of the base 12 at a position opposite to the lens frame 13. The lens holder 13 is used for mounting a transmitting lens and a receiving lens of the laser radar 100. In order to ensure the dynamic balance when the radar body 10 rotates, in the embodiment of the invention, the counterweight 15 is arranged at the position, opposite to the lens frame 13, on the radar body 10, so that the radar body 10 is balanced front and back, the center of gravity of the radar body 10 can fall on the shaft center connecting part 11, and the counterweight 15 is fixed at the position, opposite to the lens frame, of the edge of the base through the connecting vertical plate 14. In addition, the laser emitting plate 20 and the laser receiving plate 30 are respectively disposed on both sides of the connecting vertical plate 14. It is understood that when the weight of the laser transmitter panel 20 side and the weight of the laser receiver panel 30 side are equal, the weight line of the weight member 15 is located at the junction of the weight member 15 and the connecting vertical plate 14, and when the weight of the laser transmitter panel 20 side and the weight of the laser receiver panel 30 side are unequal, the weight member 15 is connected to the connecting vertical plate 14, and the weight line of the weight member 15 is biased to the lighter side. By the arrangement mode, left-right balance and front-back balance of the radar body can be further guaranteed, and the radar body 10 is enabled to rotate more stably. Meanwhile, the vertical connecting plate 14 is arranged between the laser emitting plate 20 and the laser receiving plate 30, so that the laser emitting plate 20 and the laser receiving plate 30 can be well isolated, heat dissipation and isolation can be effectively carried out, crosstalk of light is prevented, and the laser emitting plate 20 and the laser receiving plate can be mutually independent and cannot be mutually influenced.
It should be understood that the connection manner of the connecting upright plate 14 and the axle center connecting portion 11 and the base 12 is not limited to the above-described manner, and other manners are also possible, for example, the connecting upright plate 14 is only integrally formed/welded with the axle center connecting portion 11, or the connecting upright plate 14 is only integrally formed/welded with the base 12, or the connecting upright plate 14 may also be fixedly connected with the axle center connecting portion 11 and the base 12, and the like, wherein the fixed connection manner may be, for example, a fastening manner, a clamping manner, and the like.
With regard to the lens frame 13 described above, with continued reference to fig. 2, the lens frame 13 is provided with an accommodating hole 131 and a cross member 132. The receiving hole 131 is used for receiving a transmitting lens and a receiving lens of the laser radar 100, and the beam 132 is used for reinforcing the lens frame 13, so that the lens frame 13 is more stable.
In some embodiments, the weight of the weight 15 is limited, and the weight of the lens may not be well balanced, so that the dynamic balance of the radar body 10 can be achieved by reducing the weight of the lens frame 13 on the radar body 10. Specifically, the weight reduction effect can be achieved by providing the first weight reduction groove 1321 on the cross beam 132 of the lens frame 13 to remove part of the material of the cross beam 132. However, if the cross member 132 is too thin, it may easily bend or break. Therefore, a plurality of first reinforcing ribs 1322 are additionally arranged in the first weight-reducing slots 1321 to ensure the strength of the cross beam 132.
Further, the purpose of reducing the weight of the side of the radar body 10 where the lens frame 13 is arranged can be achieved by removing part of the material of the bottom of the base 12 away from the position of the lens frame 13. Specifically, as shown in fig. 3, a second weight-reducing groove 121 may be disposed at a position of the bottom of the base 12 away from the lens holder 13, so as to achieve the effect of reducing weight. Similarly, in order to ensure the strength of the base 12, a plurality of second reinforcing ribs 1211 are additionally arranged in the second lightening groove 121.
The first weight-reducing slots 1321 may be uniformly distributed on the cross beam 132 at intervals, as shown in fig. 2, a gap between two first weight-reducing slots 1321 arranged in the transverse direction and the first weight-reducing slots 1321 arranged in the longitudinal direction forms a T-shaped first reinforcing rib 1322 to stabilize the cross beam 132. It is understood that the first weight-reducing slots 1321 may have the same or different shapes and sizes, and preferably, in this embodiment, the first weight-reducing slots 1321 may have an oval shape with the same size and shape, which is more beneficial to symmetrical processing and may facilitate the processing. In addition, in the present embodiment, the second lightening grooves 121 are grooves with different depths. Due to the uneven thickness of the base 12, it is possible to provide deeper second lightening grooves 121 at locations where the base 12 is thicker and shallower second lightening grooves 121 at locations where the base 12 is thinner. It is understood that the size and depth of the second weight-reducing grooves 121 may be the same or different, and are not described herein. In general, in order to make the weight on both sides of the lens the same, it is preferable that the weight-reducing grooves are distributed in the same manner at positions on both sides of the axis of the two lenses. That is, the first weight-reducing groove 1321 and the second weight-reducing groove 121 are formed in the same size and shape at positions symmetrical to each other on both sides of the lens axis. The first weight-reducing grooves 1321 and the second weight-reducing grooves 121 are uniformly arranged in a regular manner, for example, in a row or column manner, so that the uniform arrangement facilitates symmetrical processing and the processing is more convenient. Meanwhile, the shapes of the first lightening slots 1321 and the second lightening slots 121 can be adjusted according to needs, and preferably, the embodiment of the invention adopts an elliptical structure, so that symmetrical machining can be facilitated.
It is understood that the overall weight of the rotating body can be reduced and power consumption can be reduced by providing the first weight-reducing grooves 1321 and the second weight-reducing grooves 121. Further, in some embodiments, with continued reference to fig. 2 and 3, the radar body 10 also includes at least one first secondary counterweight 16. The first secondary weight 16 may be bonded or clamped in the first weight-reducing groove 1321 or the second weight-reducing groove 121, or the first secondary weight 16 may be bonded or clamped in the first weight-reducing groove 1321 and the second weight-reducing groove 121, so as to balance the front and rear of the radar body 10. Preferably, the shape of the first secondary weight 16 is adapted to the first weight-reducing slot 1321 and the second weight-reducing slot 121, and may adopt various shapes, for example, the first secondary weight 16 may be selected to be any one of an oval shape, a rectangular shape, a wedge shape, etc. adapted to the shape of the first weight-reducing slot 1321 and the second weight-reducing slot 121. According to the embodiment of the invention, by adding the first secondary counterweight 16, the weight of one side of the radar body 10, which is provided with the lens frame 13, can be adjusted under the condition that the weight of the counterweight 15 is fixed, so that the flexibility of the overall dynamic balance adjustment of the radar body 10 is improved, and the practicability is higher. Meanwhile, the weight difference caused by the need for symmetrical machining of the first weight-reducing slot 1321 and the second weight-reducing slot 121 can also be adjusted by the first secondary weight 16, thereby simplifying the machining process.
With respect to the connecting upright plate 14 and the weight member 15, with continued reference to fig. 2, the connecting upright plate 14 is provided with a positioning boss 141, and the weight member 15 is provided with a positioning hole 151. In the process of fixedly connecting the vertical plate 14 and the weight member 15, the positioning hole 151 of the weight member 15 may be first inserted into the positioning boss 141, so as to achieve the primary positioning of the weight member 15. At this time, the mounting hole 153 of the counterweight 15 is aligned with the threaded hole of the connecting vertical plate 14, and then the screw passes through the mounting hole 153 and is screwed into the threaded hole, so that the fixing of the connecting vertical plate 14 and the counterweight 15 can be completed. The installation process of the connecting vertical plate 14 and the counterweight 15 can be simplified by additionally arranging the positioning boss 141 and the positioning hole 151, the process of aligning threaded holes is saved, and the assembly time is saved. In addition, the surface of the side of the counterweight 15, which is away from the connecting vertical plate 14, is an arc-shaped structure and is adapted to the disc structure of the base 12, so that the appearance of the laser radar 100 is more attractive.
It can be understood that: the manner of attaching the riser 14 and the weight member 15 and the surface shape of the weight member 15 are not limited to the above-described manner and shape, but may be other manners and shapes. For example, the riser 14 and the weight 15 may be connected by, for example, a snap fit connection or an adhesive connection. Wherein, the shape of weight spare can be other shapes etc. that carry out the complex with the base, and this is no longer repeated here.
In other embodiments, as shown in fig. 4, the radar body 10 further includes at least one second secondary weight 17, the weight 15 has the same number of connecting holes 152 as the second secondary weight 17, and each second secondary weight 17 has a through hole 171 for connection. The connection of the second secondary weight member 17 and the weight member 15 may be achieved by passing a screw through the connection hole 152 and the through hole 171 and then tightening both ends of the screw with a bolt. Through addding secondary counterweight 17, can progressively increase secondary counterweight 17 on counterweight 15 when counterweight 15's weight is not enough, progressively promote counterweight 15's weight, realize that counterweight 15's weight is adjustable, increased counterweight 15's practicality.
It can be understood that: the connection of the second secondary weight 17 and the weight 15 is not limited to the above-described manner, but may be in other manners, such as gluing or gluing in combination with other fastening manners.

The axis connecting portion 11 is used to connect a driving device to drive the entire laser radar 100 to rotate. One side of the axis connecting part 11 is provided with a lens frame 13, the lens frame 13 is used for installing a transmitting lens and a receiving lens of the laser radar 100, and the transmitting lens and the receiving lens are heavy, so that the gravity center of the radar body 10 deviates from the central position, and the dynamic balance of the radar body 10 during rotation is influenced. Therefore, the embodiment of the invention is provided with the weight member 15 at the other side opposite to the lens frame 13 through the connecting vertical plate 14, and the weight member 15 is arranged at the position of the edge of the base opposite to the lens frame and is also arranged between the laser emitting plate 20 and the laser receiving plate 30. By additionally arranging the connecting vertical plate 14 and the weight member 15, the radar body 10 can be effectively balanced, so that the radar body 10 is more stable in rotation, and the laser emitting plate 20 and the laser receiving plate 30 can be better isolated, thereby preventing mutual influence between the two.
