Detailed Description

The utility model aims at providing a hidden sensor driving system, so that after a sensor stretches out, the area of a hidden opening of the sensor is reduced, and the probability that foreign matters such as rainwater, dirt and the like enter the hidden opening of the sensor is reduced;

Another core of the present utility model is to provide a hidden sensor system having the hidden sensor driving system.

The following description of the embodiments of the present utility model 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 utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and 2, an embodiment of the present utility model discloses a hidden sensor driving system for driving a sensor assembly 210 to act, the hidden sensor driving system including a sensor extension movement assembly 240, a flap assembly 220, and a driving assembly 230.

The sensor extension movement assembly 240 is driven by the driving assembly 230 to move between a first position, in which the sensor assembly 210 is extended out of the sensor hidden opening 101, and a second position, in which the sensor assembly 210 is retracted into the sensor hidden opening 101. The sensor assembly 210 may be repositioned as desired by driving the sensor extension motion assembly 240 via the drive assembly 230 so that the sensor assembly 210 may be extended out of the sensor hidden opening 101 on the vehicle body 100 when the sensor assembly 210 is desired. When the sensor assembly 210 is not needed, the sensor assembly 210 may be retracted into the sensor hiding opening 101 on the vehicle body 100 so as to be hidden within the sensor hiding opening 101. It should be noted that, since the sensor assembly 210 is generally disposed at the top of the vehicle body 100, the sensor hiding opening 101 is also disposed at the top of the vehicle body 100, and the sensor assembly 210 is disposed at the top of the vehicle body 100 will be described later. Of course, one skilled in the art can also place the sensor assembly 210 at other locations of the vehicle body 100 as desired.

As shown in fig. 3, to ensure that after the sensor assembly 210 is retracted into the sensor hiding opening 101 on the vehicle body 100, the sensor assembly 210 can cover the sensor hiding opening 101, which can be the same as other sensor assemblies 210 in the prior art, and includes a vehicle-mounted sensor 211, a vehicle cover 212 disposed on the vehicle-mounted sensor 211, and a mounting seat 213, wherein the vehicle cover 212 is used for sealing the sensor hiding opening 101, and the mounting seat 213 is connected to the sensor extending movement assembly 240.

As shown in fig. 4, the flap assembly 220 includes a flap plate 224 and a flap plate moving assembly for moving the flap plate 224, and the flap plate moving assembly is driven by the driving assembly 230 to move between a third position and a fourth position. It should be noted that, the driving assembly 230 may include a driving component for driving the flap motion assembly and the sensor extending motion assembly 240 to move respectively, or may include only one driving component, and the two components may be moved simultaneously by a linkage mechanism.

When the turnover plate moving assembly is positioned at the third position, the turnover cover plate 224 covers a part of the area of the sensor hiding opening 101, and when the turnover plate moving assembly is positioned at the fourth position, the turnover cover plate 224 avoids the sensor hiding opening 101. The driving component 230 drives the turnover plate moving component, so that the position of the turnover cover plate 224 can be changed according to the requirement, and after the sensor component 210 extends out of the sensor hiding opening 101 on the vehicle body 100, the driving of the turnover plate moving component drives the turnover cover plate 224 to cover part of the area of the sensor hiding opening 101; when the sensor assembly 210 is retracted into the sensor hiding opening 101 on the vehicle body 100, the flap motion assembly is driven to drive the flap 224 to avoid the sensor hiding opening 101 so as to avoid interference with the vehicle body cover 212.

The driving assembly 230 is used for driving the sensor extension movement assembly 240 to move between the first position and the second position and driving the flap movement assembly to move between the third position and the fourth position, thereby achieving the above functions.

In summary, in the hidden sensor driving system provided by the present utility model, the sensor extension movement assembly 240 can move between the first position and the second position to drive the sensor assembly 210 to extend out of the sensor hidden opening 101 or retract into the sensor hidden opening 101. The flap motion assembly of the flap assembly 220 can drive the flap cover 224 to cover a part of the area of the sensor hiding opening 101, so that when the sensor assembly 210 extends out of the sensor hiding opening 101, the flap cover 224 can cover the part of the area of the sensor hiding opening 101 to reduce the area of the sensor hiding opening 101, thereby reducing the probability that foreign matters such as rainwater and dirt enter the sensor hiding opening 101. The utility model not only can meet the arrangement requirement of intelligent driving on the hidden sensor at the top of the vehicle, but also can solve the problem that the hidden opening 101 of the sensor is too large when the sensor is in an extending state.

As shown in FIG. 5, in one embodiment of the present utility model, sensor extension motion assembly 240 includes a sensor guide 242 and a sensor drive slider 241. Wherein the sensor guide 242 is used to limit the direction of extension of the sensor assembly 210. Taking the example that the sensor assembly 210 protrudes from the roof of the vehicle, the protruding direction of the sensor assembly 210 may be limited to the vertical direction.

In particular, the sensor guide 242 may include a first guide member 2421 and a second guide member 2422, the first guide member 2421 and the second guide member 2422 being slidably engaged in the direction of extension of the sensor assembly 210. For example, one of the first guiding component 2421 and the second guiding component 2422 can be designed as a sliding rail, and the other one is provided with a sliding groove in sliding fit with the sliding rail, and the extending direction of the sliding rail and the sliding groove is the extending direction of the sensor component 210. One of the first and second guide members 2421 and 2422 is connected with the sensor assembly 210, and the other is for fixing to the vehicle body, which in turn allows the sensor assembly 210 to extend/retract the sensor hidden opening 101 from the vehicle body under the restraining action of the first and second guide members 2421 and 2422.

The sensor driving slider 241 is driven by the driving assembly 230 to slide between the first position and the second position, and the sensor driving slider 241 is a moving direction conversion component, so that when the driving direction of the driving assembly 230 is inconsistent with the extending direction of the sensor assembly 210, the sensor assembly 210 can be driven to act along the extending direction by using the driving force of the driving assembly 230. The driving device in the vertical direction cannot be provided due to the limitation of the space on the top of the vehicle body, in this embodiment, the driving direction of the driving assembly 230 may be a horizontal direction, and the sensor assembly 210 is driven to act in the extending direction under the action of the sensor driving slider 241.

The sensor driving sliders 241 are provided with conversion sliding grooves 2413, and a plurality of conversion sliding grooves 2413 arranged in parallel may be provided on each sensor driving slider 241 in order to maintain stability of sliding. The sensor assembly 210 is slidably engaged with the conversion chute 2413, and the extending direction of the conversion chute 2413 and the sliding direction of the sensor driving slider 241 and the extending direction of the sensor assembly 210 are both acute angles. Taking the perspective of fig. 9 as an example, when the driving assembly 230 drives the sensor driving slider 241 to slide toward the first position (leftward) in the sliding direction, since the sensor assembly 210 is constrained by the sensor guide 242, only the back and forth movement in the extending direction of the sensor assembly 210 is possible, the sensor assembly 210 moves upward along the conversion chute 2413 until the sensor hiding opening 101 is completely extended (as shown in fig. 10). Similarly, when the driving assembly 230 drives the sensor driving slider 241 to slide in the sliding direction toward the second position (rightward), the sensor assembly 210 moves downward along the conversion chute 2413 until the sensor hidden opening 101 is completely retracted (as shown in fig. 8), since the sensor assembly 210 is constrained by the sensor guide 242 to reciprocate only in the extending direction of the sensor assembly 210.

In the present embodiment, the sliding direction of the sensor driving slider 241 is perpendicular to the extending direction of the sensor assembly 210. For example, the sliding direction of the sensor driving slider 241 is a horizontal direction, and the extending direction of the sensor assembly 210 is a vertical direction. It should be noted that, the above direction may be adaptively adjusted according to the installation position of the sensor assembly 210, and is not limited to the horizontal and vertical directions.

As shown in fig. 7, to ensure that the sensor driving slider 241 maintains stability of the sensor assembly 210 when moving to the first and second positions, effective support is provided for the sensor assembly 210. In the present embodiment, the conversion chute 2413 includes a chute 24131 and first and second transverse grooves 24132 and 24133 respectively communicating with both ends of the chute 24131. The chute 24131 is for effecting a conversion of the driving force, and the first transverse slot 24132 and the second transverse slot 24133 are for effecting support of the sensor assembly 210 in the first position and the second position, respectively.

The extending direction of the chute 24131 forms an acute angle with both the sliding direction of the sensor driving slider 241 and the extending direction of the sensor assembly 210. The first transverse slot 24132 and the second transverse slot 24133 are both perpendicular to the direction of extension of the sensor assembly 210. When the sensor assembly 210 moves up the conversion chute 2413 to the second transverse groove 24133, since the second transverse groove 24133 is perpendicular to the extending direction of the sensor assembly 210, the lower wall of the second transverse groove 24133 can support the sensor assembly 210 even if the driving force is removed, preventing the sensor assembly 210 from falling under the action of gravity. As the sensor assembly 210 moves down the transition chute 2413 to the first transverse slot 24132, the sensor assembly 210 is also supported because the first transverse slot 24132 is perpendicular to the direction of extension of the sensor assembly 210.

It should be noted that, in order to ensure stability, the sensor driving sliders 241 may be disposed in two parallel, the sensor assembly 210 is disposed between the two sensor driving sliders 241, and the sensor assembly 210 is driven and supported by the two sensor driving sliders 241, so as to improve stability of the sensor assembly 210 during operation.

As shown in fig. 4, in an embodiment of the present utility model, the flap motion assembly includes a flap mount 222, a flap driving part 223, and a rotating lever 221. The flip mount 222 is used to mount to the vehicle body 100, and it will be understood by those skilled in the art that the present utility model is mounted to the vehicle body 100, and means directly mounted to the vehicle body 100, or mounted to the vehicle body 100 by other means, as long as it is fixed relative to the vehicle body 100. The flip mount 222 is used to provide a mounting basis for the flap drive 223 and the rotary lever 221. The flip mount 222 has a first hinge point 2221 and a second hinge point 2222, and the first hinge point 2221 and the second hinge point 2222 may be hinge holes opened in the flip mount 222.

The flap driving part 223 is hinged to the first hinge point 2221 through a first hinge shaft 2232, and the flap cover 224 is fixed to the flap driving part 223 to drive the flap cover 224 to move between the covering position and the retracted position. When the sensor assembly 210 is extended, the flip cover 224 is in the covering position; when the sensor assembly 210 is hidden, the flip cover 224 is in the retracted position, i.e., away from the sensor hidden opening 101, and is hidden inside the sensor hidden opening 101.

The rotating lever 221 is hinged to the second hinge point 2222 through a second hinge shaft 2213, for driving the flap driving part 223 to rotate about the first hinge shaft 2232. As shown in fig. 7, in the present embodiment, the driving component 230 drives the rotating rod 221 around the second hinge shaft 2213, and the rotating rod 221 drives the flap driving portion 223 to rotate around the first hinge shaft 2232, so that the rotating direction of the rotating rod 221 can be driven to drive the flap cover 224 to move towards the covering position or towards the retracting position.

As shown in fig. 4, further, the flap driving portion 223 is provided with an arc-shaped groove 2233, the arc-shaped groove 2233 is gradually far away from the first hinge shaft 2232 from the first end to the second end, the first rotation direction of the flap driving portion 223 is the covering direction of the flap 224, and the second rotation direction of the flap driving portion 223 is the retracting direction of the flap 224.

The third hinge shaft 2215 of the rotating rod 221 is slidably fitted in the arc-shaped groove 2233, and the arc-shaped groove 2233 is gradually far away from the first hinge shaft 2232 from the first end to the second end, that is, the distance between the different positions of the arc-shaped groove 2233 and the first hinge shaft 2232 is changed, so that when the flap driving part 223 rotates around the first hinge shaft 2232, the distance between the arc-shaped groove 2233 and the second hinge shaft 2213 is changed, and when the rotating rod 221 rotates, the distance between the third hinge shaft 2215 and the second hinge shaft 2213 is unchanged, and the third hinge shaft 2215 is embedded in the arc-shaped groove 2233, so that the flap driving part 223 needs to be matched to rotate, so that the proper position of the arc-shaped groove 2233 is matched with the third hinge shaft 2215, and interference is avoided.

When the third hinge shaft 2215 moves towards the first end of the arc-shaped slot 2233, the flap driving part 223 is driven to rotate along the second rotation direction, and when the third hinge shaft 2215 moves towards the second end of the arc-shaped slot 2233, the flap driving part 223 is driven to rotate along the first rotation direction.

The sensor driving slider 241 is configured to drive the rotating rod 221 to rotate along the second hinge shaft 2213, and when the sensor driving slider 241 moves in the direction of the first position, the third hinge shaft 2215 is driven to move in the direction of the second end of the arc-shaped slot 2233, and when the sensor driving slider 241 moves in the direction of the second position, the third hinge shaft 2215 is driven to move in the direction of the first end of the arc-shaped slot 2233. In this embodiment, the sensor extending movement assembly 240 and the flap assembly 220 may be linked, so that the sensor extending movement assembly 240 and the flap assembly 220 may be completed simultaneously by one driving assembly 230, thereby reducing the occupation of the roof space.

It should be noted that the flap driving portion 223 may be composed of two symmetrically arranged flap driving plates 2231, and each flap driving plate 2231 is provided with a first hinge shaft 2232 and an arc-shaped slot 2233. The two corresponding rotating rods 221 and the turning mounting pieces 222 are also symmetrically arranged, and the two turning plate driving plates 2231, the rotating rods 221 and the turning mounting pieces 222 are uniformly distributed on two sides of the sensor hiding opening 101.

Further, the rotating rod 221 is provided with a rotating chute 2212, and the length of the rotating chute 2212 should ensure that the rotating rod 221 completes the corresponding rotating action and does not interfere with the sensor driving slider 241. The rotary chute 2212 and the third hinge shaft 2215 are respectively located at two sides of the second hinge shaft 2213, the second hinge shaft 2213 divides the rotary rod 221 into two parts, namely a first rod 2214 and a second rod 2211, the rotary chute 2212 is arranged on the second rod 2211, the third hinge shaft 2215 is arranged on the first rod 2214, in order to save space, and when the rotary rod 221 rotates, the turnover installation piece 222 is conveniently driven to complete corresponding rotation, the first rod 2214 and the second rod 2211 are arranged at an obtuse angle, and the length of the second rod 2211 is greater than that of the first rod 2214.

The sensor driving slider 241 is matched with the rotating chute 2212 through the fourth hinge shaft 2414 to drive the rotating rod 221 to rotate along the second hinge shaft 2213, and then drive the flap driving part 223 to drive the flap cover 224 to act. One end of the inclined groove can be added at the tail of the rotating chute 2212, so that after the turning plate driving part 223 drives the turning cover plate 224 to cover a part of the area of the sensor hiding opening 101, the fourth hinge shaft 2414 slides into the inclined groove, and at the moment, the inclined groove is parallel to the sliding direction of the sensor driving slide block 241, so that the stability of the turning cover plate 224 in the lifting state can be improved.

The rotational slide 2212 may be provided with corresponding access openings to facilitate sliding in and out of the fourth hinge shaft 2414. Because the motion path of the sensor assembly 210 is longer than that of the flip cover 224, the access opening is formed on the rotating chute 2212, so that the sensor driving slider 241 can move independently after the flip cover 224 is completely retracted, and the rotating rod 221 is not required to be driven to act, thereby reducing energy consumption. The fourth hinge shaft 2414 may slide out of the rotary chute 2212 through the access opening, and the sensor driving slider 241 continues to drive the sensor assembly 210 to move; accordingly, when the driving sensor assembly 210 extends, the driving sensor assembly 241 is driven by the driving assembly 230 to move, and the rotating rod 221 does not rotate because the fourth hinge shaft 2414 is not engaged with the rotating chute 2212, and as the driving sensor assembly 241 continues to move, the fourth hinge shaft 2414 slides into the rotating chute 2212 through the access opening, so as to drive the rotating rod 221 to rotate.

As shown in fig. 4, the flip mount 222 is provided with a stopper 2224 for restricting the position of the rotating lever 221, and when the rotating lever 221 abuts against the stopper 2224, the access opening corresponds to the fourth hinge shaft 2414. That is, after the flip cover 224 is completely retracted, the rotating rod 221 abuts against the limiting member 2224, so that when the flip cover 224 is lifted again, the fourth hinge shaft 2414 can smoothly enter the rotating chute 2212 through the access opening. The limiting member 2224 may be a bolt, a latch, a protrusion, or the like provided on the flip mount 222.

As shown in fig. 9, when the driving assembly 230 drives the sensor driving slider 241 to slide toward the first position (leftward) in the sliding direction, since the sensor assembly 210 is constrained by the sensor guide 242, the sensor assembly 210 can only reciprocate in the extending direction of the sensor assembly 210, and thus the sensor assembly 210 moves upward along the conversion chute 2413 until the sensor hiding opening 101 is fully extended (as shown in fig. 10). Meanwhile, the sensor driving slider 241 pushes the rotating rod 221 to rotate clockwise around the second hinge shaft 2213, and drives the third hinge shaft 2215 to move towards the second end of the arc-shaped slot 2233, so as to drive the flip cover 224 to cover a part of the area of the sensor hiding opening 101.

Similarly, when the driving assembly 230 drives the sensor driving slider 241 to slide in the sliding direction toward the second position (rightward), the sensor assembly 210 moves downward along the conversion chute 2413 until the sensor hidden opening 101 is completely retracted (as shown in fig. 8), since the sensor assembly 210 is constrained by the sensor guide 242 to reciprocate only in the extending direction of the sensor assembly 210. Meanwhile, the sensor driving slider 241 pushes the rotating rod 221 to rotate counterclockwise around the second hinge shaft 2213, drives the third hinge shaft 2215 to move toward the first end of the arc-shaped slot 2233, and drives the flip cover 224 to rotate toward the inside of the sensor hiding opening 101.

In order to reduce the size of the sensor driving slider 241, the sensor driving slider 241 may be designed in a folded plate shape, that is, includes a first slider folded plate 2411 and a second slider folded plate 2412, and the fourth hinge shaft 2414 is disposed on the first slider folded plate 2411 and the conversion chute 2413 is disposed on the second slider folded plate 2412. Since the conversion chute 2413 may be formed in a plurality, the second slider flap 2412 should be wider than the first slider flap 2411. The second slider flap 2412 may be disposed in parallel according to the extending direction of the conversion chute 2413.

As shown in fig. 7, in order to ensure stability, the flap motion assembly further includes a tensioning elastic member 2223, wherein one end of the tensioning elastic member 2223 is connected to the flip mounting member 222, and the other end is connected to the rotating rod 221, so as to drive the rotating rod 221 to drive the flap driving portion 223 to rotate along the second rotation direction. The tension elastic member 2223 is in a stretched state, and can ensure the stability of the rotating lever 221 so that it cannot be rotated at will.

As shown in fig. 6, the driving assembly 230 includes a driving motor 231 and a screw mechanism, the driving motor 231 is in transmission connection with a screw 232 of the screw mechanism, and a nut 233 of the screw mechanism is connected with a sensor driving slider 241. The lead screw 232 can be supported by the bearing 234, the driving motor 231 drives the lead screw 232 to rotate, and the nut 233 can be fixedly connected with the sensor driving slide block 241 through the fixing plate 235 so as to drive the sensor driving slide block 241 to move.

As shown in fig. 1 and fig. 2, the embodiment of the present utility model further discloses a hidden sensor system 200, which includes a sensor assembly 210 and a driving system for driving the sensor assembly 210 to act, wherein the driving system is the hidden sensor driving system disclosed in the above embodiment, and therefore, the hidden sensor driving system has all the technical effects of the hidden sensor driving system, and is not repeated herein.

As shown in fig. 3, the sensor assembly 210 includes an in-vehicle sensor 211, a vehicle body cover 212 and a mounting seat 213, wherein the vehicle body cover 212 is disposed on the in-vehicle sensor 211, the vehicle body cover 212 is used for blocking the sensor hiding opening 101, and the mounting seat 213 is connected with the sensor extending movement assembly 240. The mounting seat 213 is provided with a slide pin 214, and the slide pin 214 is in sliding fit with a conversion chute 2413. A circle of sealing strips are fixed on the inner side of the sensor hiding opening 101, the shape of the vehicle body cover plate 212 is in transitional connection with the outer shape of the vehicle roof in the retracted state of the sensor assembly 210, and the vehicle body cover plate 212 is in contact with the sealing strips, so that the sealing performance of the sensor hiding opening 101 is enhanced. After the sensor assembly 210 is extended, a partial area of the sensor hidden opening 101 is closed by the flip cover 224, and the flip cover 224 also abuts against the sealing strip. Therefore, on the premise of ensuring the function of the sensor system, the embodiment improves the problem of overlarge roof opening and improves the tightness.
