Specifically, two bar-shaped through holes may be formed on the second bracket 250, and a plurality of through holes may be formed on the first and third connection plates, and the sliding plate 200 may be slidably connected to the second bracket 250 by passing through the bar-shaped through holes and the through holes through pins, respectively, so that the sliding plate 200 may be close to or far from the support plate 100 under the action of external force.
Since the sliding plate 200 has a U-shape, a receiving space is formed between the sliding plate 200 and the supporting plate 100. The accommodating space can be used for installing other parts of the intelligent automobile warning frame.
Referring to fig. 1 and 2, in the present embodiment, the first display member 210 and the second display member 220 are both in a plate-like structure, and the first end of the first display member 210 is pivotally disposed on a side of the support plate 100 away from the sliding plate 200, in other words, the first end of the first support plate 100 is rotatable relative to the support plate 100, such that the other end of the first display member 210 can approach or depart from the support plate 100, and the other end of the first display member 210 approaches or departs from the support plate 100 in the height direction; the first end of the second display member 220 is hinged to the second end of the first display member 210.
Referring to fig. 1, 2 and 3, in the present embodiment, the first driving mechanism includes a first motor 280, a first gear 310, a first worm wheel 300, a first worm 180 and a second worm wheel 190.
The first motor 280 is disposed on the sliding plate 200 and located in the accommodating space, the first gear 310 is sleeved on the rotating shaft 290 of one of the rollers 240 and rotates synchronously therewith, and the first gear 310 and the rotating shaft 290 may be connected by a key; the first worm gear 300 is sleeved on the output shaft of the first motor 280 and rotates synchronously with the output shaft, and the first worm gear and the output shaft are still connected by adopting a key. The first worm wheel 300 and the first motor 280 are located opposite to each other on both sides of the third connecting plate.
The first worm 180 penetrates the support plate 100, both ends of the first worm 180 have thread segments, thus, one thread segment is located at one side of the support plate 100, the other thread segment is located at the other side of the support plate 100, the second worm wheel 190 is located at one side of the support plate 100 far away from the sliding plate 200 and is meshed with the first worm 180, the second worm wheel 190 is connected with the first end of the first display member 210 through a first connecting shaft, and the second worm wheel 190 and the first end of the first display member 210 rotate synchronously, wherein the first connecting shaft penetrates the second worm wheel 190 and the first end of the first display member 210 respectively, the first connecting shaft and the first end of the first display member 210 can be in key connection, and therefore, when the first worm 180 rotates, the second worm wheel 190 can be driven to rotate, and the first display member 210 is driven to rotate around the first connecting shaft.
In summary, the first driving mechanism has a first state of driving the first display 210 to rotate and moving the second end of the first display 210 toward or away from the support plate 100, or the first driving mechanism has a second state of driving one of the rollers 240 to rotate, it will be understood that when the first driving mechanism is operated, it is either in the first state or in the second state.
Referring to fig. 1,2 and 4, in the present embodiment, the second driving mechanism includes a second motor 260, a second gear 170, a third worm wheel 160, a second worm 140, a screw 120, a fourth worm wheel 130 and a slider 110.
The second motor 260 and the first motor 280, the second gear 170 and the first gear 310, the third worm gear 160 and the first worm gear 300, the second worm 140 and the first worm 180, and the fourth worm gear 130 and the second worm gear 190 are in a central symmetry relationship, and the connection relationship thereof is not described herein. It should be noted that, the first gear 310 and the second gear 170 are also in an axisymmetric relationship at the same time, so that the whole intelligent automobile warning frame can stably move forward.
Referring to fig. 5, further, the intelligent automobile warning rack further includes two fixing bases 150.
The two fixing bases 150 are oppositely disposed at one side of the support plate 100 far away from the sliding plate 200, and the screw 120 is rotatably disposed between the two fixing bases 150, wherein two ends of the screw 120 can be mounted in the fixing bases 150 through bearings, and the fourth worm wheel 130 is sleeved on the screw 120 and rotates synchronously with the screw 120.
In this embodiment, the sliding member 110 may be a nut, which may be rectangular or circular in shape, and the sliding member 110 is sleeved on the screw 120 and is in threaded fit with the screw 120, and the second end of the second display member 220 is connected to the sliding member 110 through a second connecting shaft, which passes through the second end of the second display member 220 and is in clearance fit with the second end, so that when the second worm 140 rotates, it drives the fourth worm wheel 130 to rotate, and further drives the screw 120 to rotate, so that the sliding member 110 can reciprocate on the screw 120.
In summary, the second driving mechanism has a third state of driving the second end of the second display member 220 toward or away from the first end of the first display member 210 or has a fourth state of driving the other roller 240 to rotate, and it is understood that when the second driving mechanism is operated, it is either in the third state or in the fourth state.
In the present embodiment, the switching of the first driving mechanism between the first state and the second state and the switching of the second driving mechanism between the third state and the fourth state are achieved by controlling the position of the sliding plate 200 relative to the support plate 100 by the electromagnet. Specifically, an electromagnet (not shown) is fixedly installed at a side of the support plate 100 near the sliding plate 200.
Thus, when the electromagnet is electrified, it can generate magnetic force to attract the sliding plate 200, thereby driving the sliding plate 200 to rise, when the sliding plate 200 rises, the first worm 180 will be separated from the first worm wheel 300, the second worm 140 will be separated from the third worm wheel 160, at the same time, the first worm wheel 300 will be meshed with the first gear 310, and the third worm wheel 160 will be meshed with the second gear 170, so that the first motor 280 and the second motor 260 can respectively drive one roller 240, so that the intelligent car warning frame can move forward or backward.
When the electromagnet is powered off, the sliding plate 200 moves downward relative to the supporting plate 100, the first worm gear 300 and the first gear 310, and the third worm gear 160 and the second gear 170 will gradually separate, and simultaneously, the first worm gear 300 and the first worm 180, and the third worm gear 160 and the second worm 140 will gradually mesh, so that the first worm 180 drives the first end of the first display element 210 to rotate, and the second worm 140 drives the sliding element 110 to move on the screw 120. In addition, when the sliding plate 200 moves down under the action of gravity, in order to ensure that the intelligent car warning frame is not easy to topple over, the minimum distance from the axis of the rotating shaft 290 of the roller 240 to the third connecting plate should be greater than the radius of the roller 240, so that the sliding plate 200 can contact with the ground, and the contact area with the ground is increased.
It should be noted that, in the initial state, the first display element 210 and the second display element 220 are disposed on the support plate 100 side by side, and the sliding element 110 is located at one end of the support plate 100 near the first worm 180, when the first worm 180 drives the first display element 210 to rotate, and the second worm 140 drives the sliding element 110 to move toward one end of the support plate 100 near the second worm 140, the second end of the first display element 210 will gradually rise, and the first end of the second display element 220 will also gradually rise, so that the first display element 210 and the second display element 220 gradually spread out and form a triangle together with the support plate 100.
In this embodiment, the controller 270 is fixedly mounted on the support plate 100 and located between the first motor 280 and the second motor 260, and is electrically connected to the first motor 280 and the second motor 260, respectively, and controls the first motor 280 and the second motor 260 to operate.
The controller 270 controls the forward and reverse rotation of the motor and the on-off of the electromagnet, thereby controlling the forward or backward movement of the intelligent car warning frame, and the folding and unfolding of the first display member 210 and the second display member 220. By automatic control, manual removal of the placement is avoided, thereby greatly ensuring the safety of the placer, and in addition, the occupation space of the first display member 210 and the second display member 220 in the automobile is reduced because the first display member 210 and the second display member 220 can be folded relatively.
Referring to fig. 1,3 and 5, in the present embodiment, the third display member 230 is rotatably disposed between the second end of the first display member 210 and the first end of the second display member 220, at least a portion of the third display member 230 is in the shape of an exclamation mark, and in addition, the first display member 210, the second display member 220 and the third display member 230 are all in transparent shapes, and an LED lamp electrically connected to the controller 270 is disposed therein.
In this embodiment, a battery case (not shown) may be made of a metal material, in which a storage battery for the operation of the first motor 280 and the second motor 260 is placed, and the battery case may be mounted on the controller 270 and located below the electromagnet, and fixedly connected with the controller 270, so that the electromagnet may conveniently attract the battery case to drive the sliding plate 200 to approach or separate from the supporting plate 100. In addition, because the battery box and the battery therein are added with the counter weight, the gravity center of the intelligent automobile warning frame moves downwards, and is not easy to fall down.
Referring to fig. 1, 2 and 6, in the present embodiment, the intelligent automobile warning rack further includes two ranging sensors 410.
The two ranging sensors 410 are movably disposed at the same side of the roller housing 400 of one of the rollers 240, and a rectangular slot (not shown) may be formed in the front-rear direction of the roller housing 400, and the two ranging sensors 410 are embedded in the rectangular slot, so that the distance between the two ranging sensors 410 can be adjusted, the heights of the two ranging sensors 410 with respect to the ground are uniform, the two ranging sensors 410 maintain a certain distance in the front-rear direction of the roller 240, i.e., one ranging sensor 410 is close to the front end of the roller housing 400, and the other ranging sensor 410 is close to the rear end of the roller housing 400, whereby the ranging sensors 410 can accurately measure the minimum distances between the front end and the rear end of the roller housing 400, respectively, and the shoulders, and it can be understood that the distances measured by the two ranging sensors 410 are different when the roller 240 does not move in a straight line. Taking an example that the distance measuring sensor 410 is disposed on the roller cover 400 near the first motor 280 and the distance between the distance measuring sensor 410 and the road shoulder is measured by the distance measuring sensor 410 at the front end of the roller cover 400 and is smaller than the distance between the distance measuring sensor 410 and the road shoulder at the rear end of the roller cover 400, at this time, the whole intelligent automobile warning frame will gradually move toward the road shoulder, and it can also be understood that two rollers 240 form a certain included angle with respect to the road shoulder, in order to rectify the intelligent automobile warning frame, at this time, the controller 270 can briefly disconnect the second motor 260, so that the rollers 240 corresponding to the second motor 260 stop rotating, thereby, when the distance between the front end and the rear end of the rollers 240 near the first motor 280 and the road shoulder is equal, the controller 270 turns on the second motor 260, so that the intelligent automobile warning frame will move along a straight line, and thus, the automatic rectification of the intelligent automobile warning frame is realized.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
