Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to a sensor mounting assembly and a vehicle. Background Art

[0002] Displacement sensors are essential components for modern intelligent active suspension systems and automatic adjustment functions of automobile headlights. The location and layout requirements of displacement sensors are often closely related to the up and down bounce travel of the suspension, as well as the movement angle and sensitivity requirements of the sensor.

[0003] like Figure 1 As shown, taking the automobile headlight mounting frame assembly as an example, the automobile headlight mounting frame assembly includes a subframe 21, a sensor body 22, an upper bracket 23 and a lower bracket 24. One end of the sensor body 22 is fixedly connected to the upper bracket 23 by a first connecting bolt, and the other end of the sensor body 22 is fixedly connected to the lower bracket 24 by a second connecting bolt. Due to the limitation of the process space, after the upper bracket 23 is fixedly connected to the subframe 21 by the first fixing bolt 25, the lower bracket 24 is fixedly connected to the control arm 27 by the second fixing bolt 26. However, the control arm 2 7 Due to the limitation of the structural surface, the second fixing bolt 26 can only be fixed from the Z direction, that is, tightened downward along the height direction of the vehicle body, and the fixing point can only be arranged at a specific position. In addition, the rear suspension structure is compactly arranged and the space is limited. The convenience of the installation and operation space of the sensor body 22 is greatly affected by the subframe 21 and the control arm 27. Therefore, during the fixing process of the second fixing bolt 26, due to the performance requirements of the subframe 21, the bracket structure of the subframe 21 cannot be greatly changed. No matter how it is arranged, the tool cannot avoid the space between the bracket of the subframe 21 and the surrounding parts, and cannot be assembled. Summary of the invention

In this embodiment, the first bracket 131 is fixedly connected to the sensor body 11, and the second bracket 132 is fixedly connected to the control arm 16, so as to change the fixing direction of the fixing bolt 15 from the Z-direction fixing in the prior art to the X-direction fixing, thereby improving the convenience of operation. Among them, the Z direction refers to the height direction of the vehicle body, and the X direction refers to the length direction of the vehicle body; the sensor body 11 is a displacement sensor, which is a necessary component of the modern intelligent active suspension system and the automatic adjustment function of the automobile headlights. The position arrangement requirements of the displacement sensor are often closely related to the up and down bounce stroke of the suspension and the movement angle and sensitivity requirements of the sensor.
