Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may 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 disclosure to those skilled in the art.

Therefore, there is a need for a detection device that can apply protection to a sensor assembly disposed therein.

Fig. 1 schematically shows a cross-sectional view of a detection device according to an embodiment of the present application. Referring to fig. 1, a detection apparatus 1 according to an embodiment of the present application may include: sensor assembly 11, seal assembly 12, housing 13 and drain assembly 15.

In the embodiment of the present application, the sensor assembly 11 may be mounted on the housing 13 to detect the external environment. In one embodiment of the present application, the sensor assembly 11 may be a laser for scanning the external environment to form a three-dimensional stereoscopic image. A sealing assembly 12 may be provided between the housing 13 and the sensor assembly 11 for sealing the mounting connection of the housing 13 to the sensor assembly 11. In the field of detection, the sensor assembly 11 is usually a commercially available finished assembly, i.e., the sensor assembly 11 body is packaged and has a certain waterproof function. However, the sensor assembly 11 may be further mounted on other assemblies for more complicated detection or specific purpose. For example, the laser may be mounted on an intelligent drone vehicle, e.g., at the vehicle head, to provide the vehicle with information of the surrounding environment. In this case, the laser as the sensor assembly 11 is mounted to the drone vehicle and needs to be electrically and physically connected to other components on the drone vehicle, and in actual use, the connection between the laser and the head of the drone vehicle is exposed to the outside environment. When encountering, for example, rain water may enter the interior through such a joint, thereby damaging the internal components.

Thus, according to the present embodiment, the connection between the sensor assembly 11 and the mounted housing 13 is sealed by the seal assembly 12. Furthermore, according to another embodiment of the present application, the detection device 1 may further comprise a support frame 14, the support frame 14 may be arranged inside the housing 13 and fixedly connected to the housing 13 to form a support structure for devices inside and outside the housing. For example, in this case, according to an embodiment of the present application, the sensor assembly 11 may further include: sensing element 111, sensor mount 112. The sensing element 111 may be, for example, a laser element and may be mounted to the housing 13 by a sensor mount 112. In addition, the sensor mount 112 may be further mounted to the support frame 14, so that rigid fixation of the sensing element 111 mounted on the sensor mount 112 may be ensured, contributing to enhanced stability of detection.

Fig. 2 schematically shows an enlarged partial cross-sectional view of a detection device according to an embodiment of the present application seen from the front, and fig. 3 schematically shows an enlarged partial cross-sectional view of a detection device according to an embodiment of the present application seen from the side.

As shown in fig. 2 and 3, to electrically connect the sensor assembly 11 with other components within the housing 13, the detection device 1 may further include a wire harness assembly 16, which may be inserted into the sensor assembly 11 at one end, for connecting the sensor assembly 11 with other components (not shown) within the housing 13. Since such a wire harness assembly 16 is used to make an electrical connection, damage to the components may also occur if, for example, rain water enters. Therefore, according to the embodiment of the present application, the detection apparatus 1 may further include a wire harness waterproofing member 17. The harness waterproofing member 17 may be provided on the harness assembly 16 and in close proximity to the sensor assembly 11, for example, may abut against the sensor assembly 11, thereby achieving a waterproofing effect on a connection portion between the harness assembly 16 and the sensor assembly 11.

Furthermore, according to an embodiment of the present application, as shown in fig. 3, the detection apparatus 1 may further include a first crimping assembly 18. The first crimp assembly 18 may be disposed in contact with the housing 13 and the sensor mount 112. In particular, the first crimp assembly 18 may be brought into pressure contact with the housing 13 and the sensor mount 112, i.e., pressure will be applied to the housing 13 and the sensor mount 112, thereby crimping the housing 13 and the sensor mount 112 together. In an embodiment of the present application, the seal assembly 12 may be disposed between the sensor mount 112 and the housing 13 such that when the first crimp assembly 18 applies pressure to the housing 13 and the sensor mount 112, the housing 13 and the sensor mount 112 may compress the seal assembly 12 therebetween, thereby achieving a seal. Further, according to an embodiment of the present application, the sensor mount 112 may have a groove (not shown) on a surface thereof facing the housing 13, so that when the first crimping assembly 18 applies pressure to the housing 13 and the sensor mount 112, the housing 13 and the sensor mount 112 may compress the sealing assembly 12 therebetween, so that a portion of the sealing assembly 12 may be sunk into the groove on the surface of the sensor mount 112, thereby achieving a better sealing effect.

Furthermore, according to an embodiment of the present application, as shown in fig. 3, the detection apparatus 1 may further include a second crimping assembly 19. The second crimp assembly 19 may be disposed in contact with the wire harness waterproofing assembly 17 and the sensor mount 112. In particular, the second crimping assembly 19 may be brought into pressure contact with the wire harness waterproofing assembly 17 and the sensor mount 112, that is, pressure will be applied to the wire harness waterproofing assembly 17 and the sensor mount 112, thereby crimping the wire harness waterproofing assembly 17 and the sensor mount 112 together. For example, when the second crimping assembly 19 applies pressure to the wire harness waterproofing assembly 17 and the sensor mount 112, the wire harness waterproofing assembly 17 and the sensor mount 112 can be pressed together, thereby enabling a sealing effect to be achieved for a portion of the wire harness assembly 16 entering the sensor mount 112.

Further, according to an embodiment of the present application, as shown in fig. 2 and 3, the drain assembly 15 may include: a drain pipe 151, a pipe coupling part 152, and a pipe fixing part 153. For example, the drain line 151 may be connected to the sensor assembly 11 through a pipe connection part 152. For example, the drain duct 151 may have an opening at one end thereof to open to the inside of the sensor assembly 11, and may have an opening at the other end thereof to open to the outside of the detection apparatus 1. Therefore, if, for example, rainwater enters the inside of the sensor unit 11, it can also flow out through the opening of the drain pipe 151 leading to the inside of the sensor unit 11 and out to the outside of the detection apparatus 1 via the other end opening of the drain pipe 151. Therefore, water can be prevented from accumulating inside the sensor assembly 11.

Further, in the embodiment of the present application, a pipe fixing part 153 may be provided on the pipe connection part 152 to fix the drain pipe 151 and the pipe connection part 152 together, for example, by applying pressure to the pipe connection part 152. For example, the drain pipe 151 may be a hose, and the pipe connection part 152 may be a part such as a hose joint, and the pipe fixing part 153 may be a clip. Thus, the hose can be fastened to the hose connector by means of the clip.

Therefore, according to the detection apparatus of the embodiment of the present application, by providing the waterproof structure between the sensor assembly and the housing, between the wire harness and the sensor assembly, and additionally providing the drainage structure for draining water from the inside of the sensor assembly to the outside, it is possible to provide sufficient protection for the sensor assembly in the detection apparatus.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
