Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 4, a sensor movement device for a vehicle according to an embodiment of the present invention includes: the sensor comprises a sensor 4, a fixed shell 1, a fixed part 7 and a guide part 5 which are fixedly connected with the fixed shell 1, a connecting rod 8, a sliding piece 6 and a driving module, wherein one end of the connecting rod is hinged to the fixed part 7, the other end of the connecting rod is hinged to the sensor 4, the sliding piece 6 is in sliding fit with the guide part 5 and is hinged to the sensor 4. Wherein the sensor 4 can be extended and retracted into the fixed housing 1 by the action of the link 8 and the slider 6 and the driving of the driving module.

The fixed housing 1 is provided with a through hole for the sensor 14 to go in and out, i.e. the through hole allows the sensor 4 to extend out of the fixed housing 1 and allows the sensor 4 to retract into the fixed housing 1. The shape of the through hole is adapted to the sensor 4.

For the articulation of the slider 6 and the connecting rod 8, the sensor 4 described above is provided with a first articulation mounting 11 and a second articulation mounting 12, the first articulation mounting 11 being articulated to the slider 6 and the second articulation mounting 12 being articulated to the connecting rod 8. Specifically, the first hinge mounting structure 11 and the second hinge mounting structure 12 are hinge shafts or other structures, which are not limited in this embodiment.

The sensor 4 is controlled to move according to a required track under the combined action of the connecting rod 8, the sliding piece 6 and the driving module. The stationary housing 1, the stationary part 7 and the guide part 5 do not move relatively during the movement of the sensor 4. One end of the connecting rod 8 is hinged with the fixing part 7, so that the connecting rod 8 has one relative movement freedom degree, namely the connecting rod 8 rotates around a hinged point of the connecting rod 8 and the fixing part 7; the other end of the connecting rod 8 is hinged with the sensor 4, so that the connecting rod 8 has one degree of freedom of relative movement, namely the connecting rod 8 rotates around a hinged point of the connecting rod 8 and the sensor 4; the sliding part 6 is hinged with the sensor 4, so that the sliding part 6 only has one relative movement freedom, namely the sliding part 6 rotates along the hinged point of the sliding part 6 and the sensor 4; the sliding piece 6 is in sliding fit with the guide part 5 to form a sliding motion pair. The combination of the link 8 and the slide 6 thus allows the entire sensor 4 to have only one degree of freedom of movement.

The embodiment of the utility model provides a sensor telecontrol equipment of vehicle through setting up guide part 5, slider 6, fixed part 7 and connecting rod 8, has realized under drive module, connecting rod 8 and slider 6's cooperation that sensor 4 contains translation and pivoted complex motion to realized that sensor 4 can stretch out fixed casing 1 and can retract fixed casing 1. Because the motion of the sensor 4 is complex motion comprising translation and rotation, compared with the prior art that the sensor only performs translation or rotation, the motion space required by the sensor 4 is effectively reduced, thereby reducing the space occupied by the whole device.

In the sensor movement device for a vehicle according to the above-described embodiment, the movement locus of the sensor 4 is changed by adjusting the length of the link 8, the guide angle of the guide portion 5, the shape of the guide portion 5, the horizontal distance between the fixing portion 7 and the guide portion 5, the position of the first hinge mounting structure 11, and the position of the second hinge mounting structure 12, thereby finely adjusting the movement locus of the sensor 4. For example, a small increase in the length of the link 8 or a small increase in the horizontal distance between the fixed part 7 and the guide part 5 may make the movement locus of the sensor 4 more biased toward rotation. In fig. 4, by moving the position of the first hinge mounting structure 11 to the right, the moving distance of the slider 6 can be reduced without changing the lifting distance of the sensor 4. Therefore, the sensor movement device of the vehicle can obtain different movement tracks, is suitable for the sensors 4 with different sizes, meets the design requirements of different extending positions, retracting positions and movement tracks, and has higher design freedom.

In order to reduce the space occupation, the side of the sensor 4 on which the connecting rod 8 and the slider 6 are hinged can be selected to be adjacent to the detection surface 9 of the sensor 4, i.e. the side on which the first hinge mounting 11 and the second hinge mounting 12 are located is adjacent to the detection surface 9.

The link 8 and the slider 6 can be hinged on the same side of the sensor 4 or on different sides of the sensor 4. In particular, both the link 8 and the slide 6 are one, in which case the link 8 and the slide 6 are hinged on the same side of the sensor 4. In order to improve the stability, two connecting rods 8 and two sliding pieces 6 can be selected, in this case, the fixing portions 7 correspond to the connecting rods 8 one by one, the guiding portions 5 correspond to the sliding pieces 6 one by one, one connecting rod 8 and one sliding piece 6 are hinged on one side surface of the sensor 4, and the other connecting rod 8 and the other sliding piece 6 are hinged on the other side surface of the sensor 4, that is, the fixing portions 7 and the sliding pieces 6 which correspond to each other are positioned on the same side of the sensor 4. It will be understood that the two connecting rods 8 are respectively hinged on opposite sides of the sensor 4, and correspondingly the two slides 6 are respectively hinged on opposite sides of the sensor 4.

Of course, the connecting rod 8 and the sliding member 6 may be hinged to other sides of the sensor 4, and are not limited to the above embodiment.

In the sensor moving device of the vehicle described above, one of the slider 6 and the link 8 approaches the detection surface 9. In order to further reduce the occupied space, it is optional that the slider 6 is closer to the detection surface 9 than the link 8, and the slider 6 and the fixing portion 7 are between the detection surface 9 and the other side surface opposite to the detection surface 9. As shown in fig. 1 and 2.

As shown in fig. 1 and 2, the sensor moving device of the vehicle operates on the following principle: when the sensor 4 is required to extend out of the fixed shell 1 so that the detection surface 9 of the sensor 4 reaches a preset position, the driving module drives the sliding part 6 to move upwards to drive the left side of the sensor 4 to move upwards, and further drives the connecting rod 8 to rotate anticlockwise, so that the sensor 4 rotates clockwise at a small angle while moving upwards. When the sensor 4 needs to be retracted into the fixed shell 1, the driving module drives the sliding piece 6 to move downwards, so that the sensor 4 moves reversely along the extending movement track, and the sensor 4 is retracted into the fixed shell 1. Therefore, the sensor 4 extends out of the fixed casing 1 or retracts into the fixed casing 1 along a complex motion track, and the complex motion track is a compound motion track of translation and rotation.

Further, the sensor moving device of the vehicle is small in size as a whole, and in the retracted state of the sensor 4, the fixing portion 7, the link 8, the guide portion 5, and the slider 6 are substantially overlapped with the sensor 4, which is suitable for a case where the overall arrangement height and the left-right direction space are limited. Specifically, the sensor 4 is substantially rectangular, the detection surface 9 is a surface of one end of the sensor 4 in the length direction, and the link 8 and the slider 6 are hinged to a side surface of the sensor 4 on which the long side is located.

In order to ensure that the sliding member 6 slides along the set direction, the guide portion 5 is a guide rail, and the guide rail is a linear rail or a curved rail. Specifically, if the guide rail is a curved rail, the first hinge mounting structure 11 is made to have a more complex movement track, so as to realize a complex movement track of the sensor 4. Further, the curved slide rail is an arc slide rail.

In practical applications, the guide portion 5 may be selected to have other structures, and is not limited to the above embodiment.

In the sensor movement device of the vehicle, the driving module can drive the connecting rod 8 and/or the sliding piece 6, and selection is carried out according to actual requirements. For the sake of simplifying the structure, the driving module drives the connecting rod 8 or the sliding piece 6 to operate the sensor 4. Specifically, the drive module drives the link 8 to rotate, or the drive module drives the slider 6 to slide along the guide 5. In this case, the complex movement of the sensor 4 can be realized by using a single driving member, which effectively simplifies the structure and reduces the cost.

The specific structure of the driving module is selected according to actual needs, for example, the driving module includes a driving part and a transmission mechanism, the transmission mechanism is a rack and pinion transmission mechanism, a cam mechanism, a screw lifting pair, and the like, and the driving part may be a motor, an air cylinder, or the like, which is not limited in this embodiment.

In practical application, a driving point may be additionally added to the sensor 4, and the driving module drives at the driving point, which is not limited to the above embodiment.

It will be understood that the detection surface 9 is the detection surface 9 of the sensor body. In operation, the detection surface 9 needs to protrude out of the stationary housing 1, i.e. the detection surface 9 protrudes out of the outer surface of the stationary housing 1, and the detection surface 9 points at a predetermined angle. When not in operation, the detection surface 9 is hidden inside the fixed housing 1, and the entire sensor 4 is retracted into the fixed housing 1.

The shape following design structure is combined with the fixed shell 1 after the sensor 4 is retracted into the fixed shell 1, and the sensor shell 10 and the fixed shell 1 form a complete surface, so that the influence on the appearance of the fixed shell 1 is reduced. In order to facilitate sealing, the fixed shell 1 is provided with a through hole for the sensor 4 to go in and out, a sealing element is arranged at the through hole, and the shape following design structure is connected with the fixed shell 1 in a sealing way through the sealing element.

In the above arrangement, the sliding guide limits the movement of the cleaning brush 3 to a direction parallel to the outer surface of the stationary housing 1, with only one degree of translational freedom. In the movement process of the sensor 4, the elastic pressing unit 2 always presses the cleaning brush 3 on the detection surface 9, and the cleaning brush 3 rubs against the detection surface 9 to realize cleaning. It will be appreciated that the cleaning brush 3 is located between the detection surface 9 and the resilient pressing unit 2.
