It is to be understood that the described embodiments are merely a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

At present, a sensor for an Advanced Driving Assistance System (ADAS) is attached to the inside of a Driving device through glue or the like, and inclination or shaking is often caused by shaking of the Driving device, so that a roll angle of the sensor is not zero, calibration accuracy is directly affected, and an algorithm in the ADAS System is inaccurate.

The sensor is arranged on the mounting seat, and the mounting seat is fixed on the traveling equipment through the mounting bracket, so that the stability of the sensor installation is good, the reliability is high, and the calibration accuracy is high.

The sensor fixing device of the present application will be described below with reference to the accompanying drawings. It is understood that the following description will be made by taking a traveling apparatus as an example of a vehicle and taking an example in which a sensor is mounted on a front windshield inside the vehicle, but the embodiment of the present application is not limited thereto, and the sensor may be fixed at another position as needed, and the traveling apparatus may be another type of apparatus other than a vehicle.

Fig. 1 is a schematic structural diagram of a sensor fixing device according to an embodiment of the present application.

Referring to fig. 1, the present application provides a sensor fixing device 100 for fixing at least one sensor 1 to a portion to be installed of a travel apparatus 200, the sensor fixing device 100 including: each mounting seat 2 is provided with a containing groove 21, and the containing groove 21 is used for surrounding at least part of the structure outer side of one sensor 1 so as to fix the sensor 1; and the mounting bracket 3, at least one mounting seat 2 is fixed on the mounting bracket 3, and the mounting bracket 3 is fixed on the traveling equipment.

In the above solution, the mounting seat 2 is provided for the sensor 1, that is, the sensor 1 is mounted in the mounting seat 2 through the accommodating groove 21 surrounding the sensor 1, so that the sensor 1 is stably fixed in the mounting seat 2. In addition, a plurality of mount pads 2 pass through installing support 3 to be fixed on equipment 200 of traveling, and storage tank 21 is spacing at ascending spacing in week to sensor 1, compares with the condition that certain face of each sensor 1 among the prior art is direct through the viscose fixed, and the stability of sensor 1 installation is better, and the reliability is higher to the accuracy of demarcation is higher.

The sensor 1 may be an image capturing device, in this case, in the application of the sensor 1 to the traveling device, a plurality of sensors 1 may be disposed at different positions in the traveling device 200, in other words, a plurality of sensors 1 simultaneously capture images of the detection area. And when fixing, a sensor 1 corresponds to a mount pad 2, can guarantee all to fix well sensor 1.

In the present embodiment, the number of the sensors 1 is two, and two sensors 1 are located near the front windshield 201 as an example, but the number and the mounting positions of the sensors 1 are not limited thereto, and may be flexibly set according to actual needs.

Fig. 2 is a side sectional view of a mounting seat in a sensor fixing device provided in an embodiment of the present application, and fig. 3 is a front view of the mounting seat in the sensor fixing device provided in the embodiment of the present application.

Referring to fig. 2 and 3, the mounting base 2 may be formed in a rectangular parallelepiped shape as a whole, or may be formed in another shape such as a square shape so as to be easily attached to the mounting bracket 3 and to minimize an influence on the driver's visual field.

A receiving groove 21 is formed on the surface of the mounting base 2, and a part of the structure of the sensor 1 may be received in the receiving groove 21, or the entire sensor 1 may be received in the receiving groove 21. Specifically, the wall of the accommodating groove 21 may be arranged around the outer side of a part of the structure of the sensor 1 to fix the sensor 1. The enclosure here can mean that the groove walls of the accommodating groove 21 surround the sensor 1 in a circumferential 360-degree range.

For example, the sensor 1 may be partially engaged in the receiving groove 21. Alternatively, the sensor 1 may be fixed to the accommodation groove 21 by a fastener such as a screw.

It is also possible to match the inner contour of the groove wall of the receiving groove 21 to the outer contour of the sensor 1. Therefore, the limiting effect of the accommodating groove 21 on the sensor 1 is better.

It is understood that, in order to expose the lens of the sensor 1 to the outside of the accommodating groove 21, the lens of the sensor 1 may be directed toward the notch of the accommodating groove 21. In some other examples, the lens of the sensor 1 protrudes from the notch of the receiving groove 21.

Alternatively, when the lens of the sensor 1 faces the bottom wall of the accommodating groove 21, an escape hole 22 penetrating through the mounting seat 2 may be formed in the bottom wall of the accommodating groove 21, and the lens 11 of the sensor 1 may be exposed to the outside of the accommodating groove 21 through the escape hole 22. Here, the inner hole wall of the avoiding hole 22 matches the outer contour of the lens 11, that is, the lens 11 can be exposed without generating an excessively large gap between the avoiding hole 22 and the lens 11.

In order to prevent the accommodating groove 21 from affecting the field of view of the lens 11 of the sensor 1, the thickness of the bottom wall of the accommodating groove 21 may be made smaller than the protruding height of the lens 11 of the sensor 1. Thus, the lens 11 of the sensor 1 can completely protrude from the avoiding hole 22 to the outside of the accommodating groove 21.

Referring to fig. 1, in a possible embodiment, when the number of the mounting seats 2 is plural, the plural mounting seats 2 are mounted on the mounting bracket 3 at intervals from each other.

The burring 311 may be formed by bending an end of the support plate 31 in a direction away from the support plate 31, for example. Alternatively, the burring 311 and the support plate 31 are formed separately and fixed to the end of the support plate 31 by a fastener such as welding or a screw.

In the embodiment of the present application, the number of the mounting arms 32 may be two, so that both ends of the support plate 31 may be connected to both of the mounting arms 32.

With continued reference to fig. 1, the mounting arm 32 may comprise a body portion 321 and a connecting portion 322 which are connected to one another, the body portion 321 comprising a mounting surface facing a surface to be mounted of the running gear, which surface to be mounted of the running gear may be, for example, an inner side of a vehicle roof, the connecting portion 322 being located on a side of the body portion 321 facing away from the mounting surface, and the support plate 31 being connected to an end of the connecting portion 322 facing away from the mounting surface. This makes it possible to provide the support plate 31 at a distance from the surface of the travel device to be mounted, in order to avoid interference between the mounting base 2 and structures in the travel device, such as the front windshield 201.

Here, the connecting portion 322 may be provided as a flat plate-like member in order to match the burring 311. In particular, the connecting portion 322 and the flange portion 311 may be attached to each other by a fastening member such as a screw, while the surfaces facing each other are attached to each other.

In some examples, the mounting arm 32 has an elongated mounting hole 23, and the mounting holes 23 are aligned in a straight line in the length direction of the mounting arm 32, and the mounting arm 32 can be mounted to the travel device using the mounting holes 23.

Referring now to fig. 1, a method of mounting a plurality of sensors 1 will be described.

With the mounting bracket 3 assembled, the mounting arm 32 is first screwed to the roof inner side wall 202 so that the support plate 31 is located as close as possible to the top of the front windshield 201 to minimize the impact on the driver's view.
