Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 4, a sensor movement device of a vehicle according to an embodiment of the present invention includes: the sensor 5, fixed casing 1, the fixed first fixed part 9 and the fixed part 8 that link to each other with fixed casing 1 are all fixed, and one end is articulated with first fixed part 9, the other end is articulated with the first connecting rod 4 of sensor 5, and one end is articulated with the fixed part 8 of second, the other end is articulated with the second connecting rod 10 of sensor 5. The sensor 5 can be extended out of and retracted into the stationary housing 1 by the action of the first and second connecting rods 4, 10 and the drive of the drive module.
According to the sensor movement device of the vehicle, provided by the embodiment of the invention, the first fixing part 9, the second fixing part 8, the first connecting rod 4, the second connecting rod 10 and the sensor 5 form a four-bar mechanism through the arrangement of the first connecting rod 4 and the second connecting rod 10, and the sensor 5 performs complex movement including translation and rotation through the driving of the driving module and the action of the four-bar mechanism, so that the sensor 5 can extend out of the fixing shell 1 and retract into the fixing shell 1; because the motion of the sensor 5 is complex motion including translation and rotation, compared with the conventional sensor which only translates or rotates, the motion space required by the sensor 5 is effectively reduced, and the space occupied by the whole device is reduced.
In order to shorten the stroke of the sensor 5 and further reduce the occupied space, the first connecting rod 4 and the second connecting rod 10 are hinged on the same side of the sensor 5, and the hinged side surface of the sensor 5, on which the first connecting rod 4 and the second connecting rod 10 are hinged, is opposite to the detection surface 11 of the sensor 5. Along the length direction of the detection surface 11, the hinge positions of the sensor 5 and the first connecting rod 4 and the hinge positions of the sensor 5 and the second connecting rod 10 are distributed in sequence. The longitudinal direction of the detection surface 11 corresponds to the movement direction of the sensor 5 when it is extended or retracted into the stationary housing 1.
Specifically, as shown in fig. 2, the hinge position of the sensor 5 and the first link 4 is denoted as a first hinge position e, and the hinge position of the sensor 5 and the second link 10 is denoted as a second hinge position d, the first hinge position e and the second hinge position d being sequentially distributed along the length direction of the detection surface 11.
The relative positions of the first link 4 and the second link 10 are selected according to actual needs. For example, the first link 4 is higher than the second link 10, or the first link 4 is lower than the second link 10, or the first link 4 and the second link 10 spatially intersect. When the first link 4 and the second link 10 spatially intersect, one end of the first link 4 is lower than one end of the second link 10, the other end of the first link 4 is higher than the other end of the second link 10, and the first link 4 and the second link 10 are not directly connected.
In practical applications, the first link 4 is higher than the second link 10 in one embodiment for ease of installation.
The lengths of the first link 4 and the second link 10 are designed according to the actual situation, for example, according to the positions of the first link 4 and the second link 10. For example, if the first link 4 is higher than the second link 10, the length of the first link 4 is smaller than the length of the second link 10. The present embodiment does not limit the length of the first link 4 and the second link 10.
In practical applications, the first link 4 and the second link 10 may be alternatively hinged to other sides of the sensor 5, or the first link 4 and the second link 10 may be hinged to different sides of the sensor 5, which is not limited to the above embodiment.
In the sensor movement device of the vehicle, the fixed housing 1 is provided with a through hole for the sensor 5 to go in and out, and the through hole allows the sensor 5 to extend out of the fixed housing 1 and allows the sensor 5 to retract into the fixed housing 1. The shape of the through-hole is adapted to the sensor 5.
In order to reduce the influence on the outer shape of the stationary housing 1, it is necessary to achieve a sealed connection of the sensor 5 to the stationary housing 1 and to close the through-hole in the resting state of the sensor 5. It is understood that the stay state includes an extended state in which the sensor 5 is extended out of the fixed housing 1 and reaches a preset position, and a retracted state in which the sensor 5 is retracted into the fixed housing 1.
In the sensor movement device of the vehicle, the horizontal width of the sensor 5 at the through hole is changed along with the movement of the sensor 5, the change amount is large, and the sealing is ensured only by arranging the conformal design structure on the sensor shell of the sensor 5, so that the sensor movement device is difficult to realize. In order to facilitate closing the through hole and sealing, the sensor movement device of the vehicle may further comprise a movable sealing cover plate 3; if the sensor 5 is in a stop state, the sensor 5 is connected with the fixed shell 1 in a sealing way, the sealing cover plate 3 is positioned on one side of the sensor 5 opposite to the detection surface 11, the sealing cover plate 3 shields a gap between the sensor 5 and the fixed shell 1, and the sealing cover plate 3 is connected with the fixed shell 1 and the sensor 5 in a sealing way. Specifically, the sealing cover plate 3 is in sealing connection with the fixed housing 1 and the sensor 5, which means that the sealing cover plate 3 is in sealing connection with the fixed housing 1, and the sealing cover plate 3 is in sealing connection with the sensor 5.
In the above structure, the sealing through hole is realized by the combined action of the sensor 5 and the sealing cover plate 3, and the sealing connection with the fixed shell 1 is realized.
The shape of the sealing cover plate 3 is selected according to actual needs. In order to facilitate ensuring the sealing, the sealing cover plate 3 may include: and the two side plates are respectively fixed on two sides of the main cover plate. Of course, the sealing cover plate 3 may be alternatively configured, which is not limited in this embodiment.
The sealing cover plate 3 needs to move, and a driving structure for driving the sealing cover plate 3 is needed. Optionally, the sealing cover 3 is connected to the sensor 5, and the sealing cover 3 is a follower of the sensor 5. In this way, the sealing cover plate 3 moves along with the movement of the sensor 5, and a driving structure is not needed, so that the structure is simplified, and the cost is reduced.
In practical application, a driving structure may be provided to individually drive the sealing cover plate 3, which is not limited to the above embodiment.
In order to facilitate the sealing cover plate 3 to move along with the sensor 5, the cover plate guiding portion 2 may be disposed in the fixed housing 1, one end of the sealing cover plate 3 is slidably matched with the cover plate guiding portion 2, and the other end of the sealing cover plate 3 is hinged with the sensor 5.
It will be appreciated that the sealing cover 3 is hinged to the sensor 5 on the side opposite the detection face 11. At this time, the hinge side of the sensor 5 where the first link 4 and the second link 10 are hinged is opposite to the detection surface 11 of the sensor 5, that is, the sealing cover 3, the first link 4, and the second link 10 are hinged to the opposite side of the sensor 5 from the detection surface 11. At this time, the space on the side of the sensor 5 facing away from the detection surface 11 is fully utilized, and the space occupied by the whole device is effectively reduced.
The sealing cover plate 3 is in sliding fit with the cover plate guide part 2, specifically, one of the cover plate guide part 2 and the sealing cover plate 3 is provided with a sliding groove, and the other is provided with a sliding piece in sliding fit with the sliding groove.
The sliding groove is a straight sliding groove or a curved sliding groove, and further, the curved sliding groove is an arc sliding groove. In the practical application process, if the chute is a curved chute, the sealing cover plate 3 has a more complex motion track, so that the complex motion track of the sensor 5 is realized.
The sliding member may have a structure such as a slider or a protrusion, which is not limited in this embodiment.
In order to reduce the influence on the outer shape of the fixed housing 1, the sensor 5 is in a set range in a height difference between the sealing cover 3 and the sensor 5 in a resting state including an extended state and a retracted state of the sensor 5. Specifically, in the retracted state of the sensor 5, the difference in height between the sealing cover plate 3 and the sensor 5 may be zero, that is, the sealing cover plate 3 is flush with the sensor 5, and at this time, the sealing cover plate 3 and the sensor 5 may be flush with the outer surface of the fixed housing 1. In the above-mentioned sensor 5 in the extended state, the height difference between the optional sealing cover plate 3 and the sensor 5 is not zero, so that the sealing cover plate 3 is arranged.
In the practical application process, when the sensor 5 is in an extending state, the sealing cover plate 3 is flush with the sensor 5, and at the moment, the height difference between the sealing cover plate 3 and the sensor 5 is zero; the sensor 5 described above is not limited to the above embodiment, but a small height difference exists between the sealing cover 3 and the outer surface of the stationary housing 1 and a small height difference exists between the sensor 5 and the outer surface of the stationary housing 1 in the retracted state.
In the sensor movement device of the vehicle, the driving module may drive the first link 4, the second link 10, or both the first link 4 and the second link 10. In order to simplify the structure and reduce the cost, the driving module can be selected to drive the first connecting rod 4 to rotate, or the driving module can be selected to drive the second connecting rod 10 to rotate. At this time, the sensor 5 can perform complex motions including translational motion and rotational motion by one driving part, so that the structure and control are effectively simplified, and the cost is reduced.
In the practical application process, a driving point may be alternatively set on the sensor 5, and the driving module drives at the driving point, which is not limited to the above embodiment.
The specific structure of the driving module is selected according to actual needs, for example, the driving module comprises a driving part and a transmission mechanism, the transmission mechanism is a gear-rack transmission mechanism, a cam mechanism, a spiral lifting pair and the like, and the driving part can be a motor or a cylinder and the like; of course, the above-mentioned driving module is selected to include only driving parts, for example, directly driving the first link 4 or the second link 10 by using a motor, or directly driving the first link 4 or the second link 10 by using a cylinder, which is not limited in this embodiment.
The specific structure of the sensor 5 is selected according to actual needs. For ease of installation, the above-mentioned sensor 5 comprises: the sensor comprises a sensor body, a sensor shell fixedly connected with the sensor body, a first hinge mounting structure fixed on the sensor shell or the sensor body, and a second hinge mounting structure fixed on the sensor shell or the sensor body; wherein the first link 4 is hinged with the first hinge mounting structure and the second link 10 is hinged with the second hinge mounting structure. Specifically, the first hinge mounting structure and the second hinge mounting structure are both hinge shafts or other structures, which are not limited in this embodiment.
It will be appreciated that the detection surface 11 is the detection surface 11 of the sensor body. In operation, the detection surface 11 needs to protrude from the stationary housing 1, i.e. the detection surface 11 protrudes from the outer surface of the stationary housing 1, and the detection surface 11 is directed at a predetermined angle. When not in operation, the detection surface 11 is hidden inside the fixed housing 1, and at this time, the entire sensor 5 is retracted into the fixed housing 1. The first hinge mounting structure, the second hinge mounting structure, the sensor body and the sensor housing are fixed together without relative movement during movement.
In order to facilitate ensuring the sealing connection between the sensor 5 and the fixed housing 1, the sensor housing is provided with a conformal design structure, and the conformal design structure is in sealing connection with the fixed housing 1 when the sensor 5 is in a stay state.
The specific structure of the follower design structure is selected according to actual needs, and this embodiment is not limited thereto.
The shape-following design structure is combined with the fixed shell 1 after the sensor 5 is retracted into the fixed shell 1, and the sensor shell is in sealing connection with the fixed shell 1, so that the influence on the appearance of the fixed shell 1 is reduced. Moreover, at this time, the sensor housing is mainly used to be combined with the outer surface portion of the fixed housing 1, and the conformal design structure accommodates the difference between the shapes of the sensor housing and the outer surface itself of the fixed housing 1.
In order to facilitate sealing, the fixed housing 1 is provided with a through hole for the sensor 5 to go in and go out, a sealing element is arranged at the through hole, and the conformal design structure is in sealing connection with the fixed housing 1 through the sealing element. When the device includes the sealing cover plate 3, the sealing cover plate 3 is hermetically connected to the stationary housing 1 through the sealing member.
The type of the sealing member is selected according to actual needs, and this embodiment is not limited thereto.
In the practical application process, the sensor 5 can be always in sealing connection with the fixed shell 1 in the moving process by adjusting the conformal design structure.
In the sensor movement device of the vehicle, the sensor 5 extends out of the fixed housing 1 to work, and in the extending state, the detection surface 11 of the sensor 5 is easier to deposit foreign matters such as dust, thereby affecting the detection reliability and the service life. In order to improve the detection reliability and the service life, the sensor movement device of the vehicle further comprises a cleaning module, which is arranged on the fixed housing 1 and is used for cleaning the detection surface 11 of the sensor 5.

In the above-described device, the sliding guide limits the movement of the cleaning brush 6 in a direction parallel to the outer surface of the stationary housing 1, with only one translational degree of freedom. During the movement of the sensor 5, the elastic pressing unit 7 always presses the cleaning brush 6 on the detection surface 11, and the cleaning brush 6 rubs against the detection surface 11 to realize cleaning, as shown in fig. 2, at a contact position of the cleaning brush 6 and the detection surface 11 is a friction position g. It will be appreciated that the cleaning brush 6 is located between the detection surface 11 and the resilient pressing unit 7. The device achieves automatic pressing of the cleaning brush 6, so that the detection surface 11 of the sensor 5 is automatically cleaned when the sensor 5 moves.
The specific structure and type of the elastic pressing unit 7 are selected according to actual needs, and the embodiment is not limited to this, for example, the elastic pressing unit 7 is a spring or a pneumatic spring. Specifically, taking the above elastic pressing unit 7 as an example, one end of the spring far away from the detection surface 11 is fixed on the fixed housing 1, one end of the spring near to the detection surface 11 is fixedly connected with the cleaning brush 6, and the length direction of the spring is parallel to the outer surface of the fixed housing 1.
The specific type of the above-mentioned cleaning brush 6 is selected according to actual needs. Optionally, the cleaning brush 6 is provided with a cleaning agent pipeline for conveying cleaning agent, and the cleaning brush 6 automatically seeps out the cleaning agent in the process of friction between the cleaning brush 6 and the detection surface 11, so that a better cleaning effect is realized.
In the practical application process, the cleaning agent can be sprayed by additionally arranging a cleaning agent nozzle on the cleaning brush 6, and the cleaning agent nozzle sprays the cleaning agent in the motion process of the sensor 5 to realize high-efficiency cleaning.
The type of the above-mentioned cleaning agent is selected according to actual needs, and this is not limited in this embodiment.
In the sensor movement device of the vehicle, in order to ensure movement reliability and service life, each hinge point and the sliding fit structure should have lower surface roughness and higher strength, and have good lubrication.

as shown in fig. 1-4, when the sensor 5 is required to extend out of the fixed housing 1 and reach a preset detection position, and the detection surface 11 reaches a set angle, the driving module drives the first connecting rod 4 to rotate anticlockwise and drives the second connecting rod 10 to rotate anticlockwise, so that the sensor 5 moves outwards and rotates anticlockwise, and the detection surface 11 extends out of the outer surface of the fixed housing 1 and reaches the preset detection position; during the movement, friction occurs between the detection surface 11 and the cleaning brush 6, so that the detection surface 11 is cleaned. In the moving process, the sensor 5 drives the sealing cover plate 3 to move; when reaching the predetermined detection position, the right edge of the detection surface 11 just reaches the inner wall of the through hole of the fixed shell 1, so that partial sealing of the through hole is realized, the part of the sealing cover plate 3 is retracted into the fixed shell 1, and the part of the sealing cover plate 3, which does not extend into the fixed shell 1, is in sealing connection with the sensor 5 and the inner wall of the through hole, thereby meeting the sealing requirement, also maintaining the streamline of the appearance of the fixed shell 1 and obtaining better aerodynamic effect.
When the sensor 5 is required to retract into the fixed shell 1, the driving module drives the first connecting rod 4 to rotate clockwise, so that the whole device moves reversely along the extending movement track, the sensor 5 is retracted into the fixed shell 1, and meanwhile, the sensor 5, the sealing cover plate 3 and the outer surface of the fixed shell 1 form a complete surface. In the process, the cleaning brush 6 again rubs against the detection surface 11 of the sensor 5, and the detection surface 11 is cleaned.
The sensor movement device of the vehicle provided in the above embodiment can realize that the sensor 5 under a single driving module extends out of the fixed housing 1 and retracts into the fixed housing 1 along a complex movement track, and simultaneously realize that the outer surface of the fixed housing 1 is sealed in a sealing manner, and clean the detection surface 11 of the sensor 5 in the process. The sensor movement device of the vehicle has simple structure and easy realization, can obtain different movement tracks by modifying the hinging positions of the first connecting rod 4 and the second connecting rod 10 and the lengths of the first connecting rod 4 and the second connecting rod 10, is suitable for the sensors 5 with different sizes, has different design requirements on the extending position, the retracting position and the movement tracks, and has higher design freedom. Moreover, the sensor movement device of the vehicle has a smaller overall size and is concentrated in the plane of the sensor 5, and is suitable for the situation that the overall arrangement height is limited.
