Description

Technical Field

[0001] The present invention belongs to the technical field of parking equipment, and in particular relates to an early warning device for parking equipment. Background Art

[0002] With the increasing number of household cars, the demand for parking in cities is also increasing, and various parking equipment has emerged. Barriers are commonly used early warning devices in parking equipment, which are used to warn and restrict motor vehicles from entering and exiting parking equipment. Barriers use a warning pole to intercept passing vehicles. In actual use, the warning pole will be ignored due to problems such as driver distraction and lack of concentration, and vehicles often directly hit the warning pole and break it.

[0003] Existing technologies usually use the following means to solve the problem. For example, the national patent publication number CN109440686B discloses a barrier pole with enhanced warning function, which adopts a split structure. The warning auxiliary pole can effectively warn passing vehicles to stop in time for inspection.

[0004] However, the above solution has a fixed structure, and the enhanced warning effect is relatively limited. In addition, when a collision occurs with a vehicle, the warning sub-pole will still be damaged, causing economic losses, and cannot reduce the damage to the vehicle, and the warning and protection effects are poor. Summary of the Invention

[0005] The purpose of the present invention is to provide a parking equipment early warning device in response to the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a parking equipment early warning device, comprising:

[0007] Box shell;

[0008] A lifting rod, wherein the lifting rod is a hollow tubular structure, one end of the lifting rod extends into the box shell, and a driving member for driving the lifting rod to lift and fall is provided in the box shell;

[0009] A lifting assembly, wherein the lifting comprises a rotating disk rotatably connected to the housing, a shaft sleeve being fixed on the rotating disk, a lifting rod passing through a one-way bearing and rotatably connected to the shaft sleeve, a gear being fixed to one end of the lifting rod located in the rotating disk, an arc-shaped rack being fixed on the inner wall of the housing, and the gear and the arc-shaped rack being meshed with each other;

[0010] A warning assembly includes four warning signs arranged in a circumferential array on the lifting rod.

[0011] Furthermore, the warning component also includes four LED light strips respectively installed on the four warning signs. The LED light strips are arranged in parallel along the length direction of the warning signs, and a switch is provided in the lifting rod.

[0012] Furthermore, the switch includes a hollow tube embedded in the lifting rod, and four conductive plates are arranged in a circumferential array on the side wall of the hollow tube. A conductive ball is provided in the hollow tube, and the conductive ball is electrically connected to the power supply. The four conductive plates are respectively electrically connected to four LED light strips.

[0013] Furthermore, the hollow tube is in a conical frustum-shaped structure, the end of the hollow tube with a smaller diameter is located close to the box shell, and insulating sheets are evenly arranged on the surface of the conductive sheet.

[0014] Furthermore, the driving member includes a motor installed in the box shell, the output end of the motor is connected to a worm, a worm wheel is coaxially fixed on the rotating disk, and the worm wheel and the worm wheel are engaged with each other.

[0015] Furthermore, it also includes a dust removal component, which includes an air pump fixed on the inner wall of the box shell, a pressure block fixed on the valve stem of the air pump, a protruding block fixed on the peripheral side wall of the rotating disk, the output end of the air pump is connected to the air collecting box, the output end in the air collecting box is connected to the end of the lifting rod through a connecting pipe, a pressure valve is installed at the connection between the connecting pipe and the air collecting box, and air holes are equidistantly provided on the side wall of the lifting rod at the warning sign.

[0016] Furthermore, a carbon fiber electric heating plate is installed in the gas collecting box, a touch pressure switch is installed on the inner wall of one end of the hollow tube close to the box shell, a buffer spring is provided on the surface of the touch pressure switch, and the carbon fiber electric heating plate is electrically connected to the power supply through the touch pressure switch.

[0017] Compared with existing technologies, the advantages of this parking equipment early warning device are:

[0018] 1. In the present invention, when a vehicle collides with the lifting rod, the lifting rod can rotate to reduce the damage caused by the collision with the vehicle, and by providing a one-way bearing, a gear and an arc-shaped rack, the lifting rod will rotate 90 degrees axially each time the lifting rod is lifted and lowered, and each warning sign will be rotated to a vertical position in turn. Compared with the existing technology, the frequently changed warning signs are more likely to attract the driver's attention, thereby reducing the possibility of ignoring the lifting rod due to distraction, inattention and other problems, and reducing the probability of collision accidents.

[0019] 2. The present invention provides a hollow tube, a conductive sheet and a conductive rolling ball. When the lifting rod is in a horizontal state, under the action of gravity, the conductive ball is always in contact with the conductive sheet at the bottom, so that the LED light strip below the lifting rod lights up, providing lighting for the warning sign, improving the night-time recognition of the lifting rod, and when the axis of the lifting rod rotates, only one LED light strip is powered on and lights up, thereby reducing power consumption while ensuring the warning effect.

[0020] 3. The present invention uses insulating sheets arranged at intervals and a hollow tube with a conical frustum-shaped structure. When the lifting rod is lifted and lowered, the conductive ball will roll along the axial direction of the hollow tube. The insulating sheets arranged at intervals will intermittently block the contact between the conductive ball and the conductive sheets, causing the LED light strip to light up intermittently. That is, when the lifting rod is lifted and lowered, the LED light strip is in a flashing state, further improving the warning effect.

[0021] 4. The present invention provides an air pump, a protruding block and an air collecting box. When the lifting rod is lifted and lowered, the air pump continuously fills the air collecting box with air. When the air pressure reaches the threshold of the pressure valve, the air is discharged from the air hole to blow away the dust on the surface of the warning sign, thereby improving its recognition. The more vehicles pass by, the more frequently the lifting rod is lifted, and the more easily the surface of the warning sign is covered with dust brought up by the vehicles. At this time, the faster the air collecting box is inflated, the more frequent the blowing and cleaning is.

[0022] 5. In the present invention, water splashed by vehicles passing by will cover the surface of the warning sign, and in cold weather, it is easy to freeze, increasing the overall weight of the lifting rod and increasing the operating load of the motor. By arranging a carbon fiber electric heating plate and a touch-pressure switch, when the lifting rod is lifted, the conductive ball falls and collides with the touch-pressure switch, so that the carbon fiber electric heating plate is energized to heat the air in the air collecting box. On the one hand, the air expands due to heat, which can increase the kinetic energy of the airflow when it is blown out. On the other hand, it can melt the frost on the surface of the warning sign, reduce the weight of the lifting rod, and reduce the operating load of the motor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0030] like Figure 1-Figure 5 As shown, a parking equipment warning device includes: a box shell 1, a lifting rod 2, a lifting assembly and a warning assembly. The lifting rod 2 is a hollow tubular structure. One end of the lifting rod 2 extends into the box shell 1. A driving member for driving the lifting rod 2 to lift and fall is provided in the box shell 1. The driving member includes a motor 13 installed in the box shell 1. The output end of the motor 13 is connected to a worm 14. A worm gear 15 is coaxially fixed on the rotating disk 3. The worm gear 15 and the worm 14 are engaged with each other. When working, the motor 13 runs and drives the worm gear 15 to rotate forward and reverse through the worm 14 to realize the lifting and falling of the lifting rod 2.

[0031] The lifting includes a rotating disk 3 that is rotatably connected to the housing 1, a shaft sleeve 4 is fixed on the rotating disk 3, and the lifting rod 2 is rotatably connected to the shaft sleeve 4 through a one-way bearing 5. A gear 24 is fixed to one end of the lifting rod 2 located in the rotating disk 3, and an arc-shaped rack 25 is fixed to the inner wall of the housing 1. The gear 24 and the arc-shaped rack 25 are meshed with each other. Due to the setting of the one-way bearing 5, when the lifting rod 2 is lifted, the gear 24 moves and rotates along the arc-shaped rack 25. If the one-way bearing 5 does not rotate in this direction, the lifting rod 2 will not rotate around its axis. When the lifting rod 2 falls, the one-way bearing 5 is locked in this direction, and the lifting rod 2 will follow the gear 2. 4 rotates 90 degrees synchronously. Since the intersection where vehicles enter or exit is fixed, that is, the direction of vehicle travel facing each lifting rod 2 is fixed, the one-way bearing 5 can rotate freely in this direction. When a vehicle collides with the lifting rod, the lifting rod 2 can rotate to reduce the damage caused by the collision with the vehicle. In addition, each time the lifting rod 2 is raised and lowered, the lifting rod 2 will rotate 90 degrees axially to rotate each warning sign 6 to a vertical position in turn. Compared with the existing technology, the frequently changed warning signs are more likely to attract the driver's attention, thereby reducing the possibility of ignoring the lifting rod 2 due to distraction, inattention and other problems, and reducing the probability of collision accidents.

[0032] The warning component includes four warning signs 6 arranged in a circumferential array on the lifting rod 2. In this embodiment, each warning sign 6 is painted in a different color and has different slogans written on it, such as "Slow down" and "Drive carefully". The warning component also includes four LED light strips 7 respectively installed on the four warning signs 6. The LED light strips 7 are arranged in parallel along the length direction of the warning signs 6, and a switch is provided in the lifting rod 2.

[0033] The switch includes a hollow tube 8 embedded in the lifting rod 2, and four conductive plates 9 are arranged in a circumferential array on the side wall of the hollow tube 8. A conductive ball 10 is provided in the hollow tube 8, and the conductive ball 10 is electrically connected to the power supply. The four conductive plates 9 are respectively electrically connected to the four LED light strips 7. When the lifting rod 2 is in a horizontal state, under the action of gravity, the conductive ball 1 is always in contact with the conductive plate 9 located at the bottom, so that the LED light strip 7 located below the lifting rod 2 lights up, providing lighting for the corresponding warning sign 6, and improving the night recognition of the lifting rod 2. Moreover, when the axis of the lifting rod 2 rotates, one and only one LED light strip 7 is powered on and lights up, thereby reducing energy consumption while ensuring the warning effect.

[0034] The hollow tube 8 has a conical frustum-shaped structure, and the end of the hollow tube 8 with a smaller diameter is located on the side close to the box shell 1. Insulating sheets 12 are evenly arranged on the surface of the conductive sheet 9. When the lifting rod 2 is in a horizontal state, the conductive ball 10 will roll toward the end of the hollow tube 8 away from the box shell 1. When the lifting rod 2 is lifted, the conductive ball 10 is located in the hollow tube 8 and rolls at the end close to the box shell 1. During the lifting and falling process of the lifting rod 2, the conductive ball 10 will roll along the axial direction of the hollow tube 8. The insulating sheets 12 arranged at intervals will intermittently block the contact between the conductive ball 10 and the conductive sheet 9, causing the LED light strip 7 to be intermittently lit, that is, during the lifting and falling process of the lifting rod 2, the LED light strip 7 is in a flashing state, further improving the warning effect.

[0035] It also includes a dust removal component, which includes an air pump 16 fixed on the inner wall of the box shell 1, a valve stem is provided in the air pump 16, and when the valve stem moves back and forth in the air pump 16, it will continuously output air to the output end, a pressure block 17 is fixed on the valve stem of the air pump 16, and a protruding block 18 is fixed on the peripheral side wall of the rotating disk 3. The output end of the air pump 16 is connected to the air collecting box 19, and the output end in the air collecting box 19 is connected to the end of the lifting rod 2 through a connecting pipe 20. A pressure valve is installed at the connection between the connecting pipe 20 and the air collecting box 19, and air holes 21 are equidistantly provided on the side wall of the lifting rod 2 at the warning sign 6. During operation, when the lifting rod 2 is lifted and lowered, the rotating disk 3 drives the protruding block 18 to rotate synchronously. When the protruding block 18 sweeps over the pressure block 17, it will squeeze the valve stem in the air pump 16 through the pressure block to move back and forth once, so that the air pump 16 continues to fill air into the air collecting box 19. When the air pressure reaches the threshold of the pressure valve, the air is discharged from the air hole 21, blowing away the dust on the surface of the warning sign 6 to improve its recognition. The more vehicles pass by, the more frequently the lifting rod 2 is lifted, and the surface of the warning sign 6 is more likely to be covered with dust brought up by the vehicles. At this time, the faster the speed of inflating the air collecting box is, the more frequent the blowing and cleaning is.

[0036] A carbon fiber electric heating plate 22 is installed in the gas collecting box 19, and a touch pressure switch 23 is installed on the inner wall of one end of the hollow tube 8 close to the box shell 1. A buffer spring 11 is provided on the surface of the touch pressure switch 23. The carbon fiber electric heating plate 22 is electrically connected to the power supply through the touch pressure switch 23. The water splashed by the vehicle will cover the surface of the warning sign 6, and it is easy to freeze in cold weather, increasing the overall weight of the lifting rod 2 and the operating load of the motor 13. By setting the carbon fiber electric heating plate 22 and the touch pressure switch 23, when the lifting rod 2 is lifted, the water splashed by the vehicle will cover the surface of the warning sign 6 and it is easy to freeze in cold weather, increasing the overall weight of the lifting rod 2 and the operating load of the motor 13. When the vehicle is lifted up, the conductive ball 10 falls and collides with the touch-pressure switch 23, so that the carbon fiber electric heating plate 22 is energized and works, heating the air in the air collecting box 19. On the one hand, the air expands due to heat, which can increase the kinetic energy of the air flow when it is blown out. On the other hand, it can melt the frost on the surface of the warning sign 6, reduce the weight of the lifting rod, and reduce the operating load of the motor 13. When there is no vehicle, the lifting rod 2 is in a horizontal state, and the conductive ball 10 will move to the end of the hollow tube 8 away from the touch-pressure switch 23, so that the carbon fiber electric heating plate 22 is powered off, reducing costs.

[0037] The working principle of the present invention is as follows:

[0038] When working, the motor 13 runs, and the worm 14 drives the worm wheel 15 to rotate forward and reverse, thereby lifting and lowering the lifting rod 2;

[0039] When a vehicle collides with the lifting rod, the lifting rod 2 can rotate to reduce the damage caused by the collision with the vehicle. Each time the lifting rod 2 is raised and lowered, the lifting rod 2 will rotate 90 degrees axially, and each warning sign 6 will be rotated to a vertical position in sequence. Compared with the existing technology, the frequently changing warning signs are more likely to attract the driver's attention, thereby reducing the possibility of ignoring the lifting rod 2 due to distraction, lack of concentration and other problems, and reducing the probability of collision accidents.

[0040] When the lifting rod 2 is in a horizontal state, under the action of gravity, the conductive ball 1 is always in contact with the conductive sheet 9 at the bottom, so that the LED light strip 7 below the lifting rod 2 lights up, providing lighting for the corresponding warning sign 6, improving the nighttime recognition of the lifting rod 2. In addition, when the lifting rod 2 axis rotates, only one LED light strip 7 is powered on and lights up, thereby reducing power consumption while ensuring the warning effect.

[0041] When the lifting rod 2 is lifted, the conductive ball 10 is located in the hollow tube 8 and rolls near one end of the box shell 1. During the lifting and falling process of the lifting rod 2, the conductive ball 10 rolls along the axial direction of the hollow tube 8. The insulating sheets 12 arranged at intervals intermittently block the contact between the conductive ball 10 and the conductive sheet 9, so that the LED light strip 7 is intermittently lit. That is, during the lifting and falling process of the lifting rod 2, the LED light strip 7 is in a flashing state, further improving the warning effect.

[0042] When the lifting rod 2 is lifted and lowered, the rotating disk 3 drives the protruding block 18 to rotate synchronously. When the protruding block 18 sweeps over the pressure block 17, the valve stem in the air pump 16 is squeezed by the pressure block to move back and forth once, so that the air pump 16 continuously fills the air collecting box 19 with air. When the air pressure reaches the threshold value of the pressure valve, the air is discharged from the air hole 21, blowing away the dust on the surface of the warning sign 6 to improve its recognition. In addition, the more vehicles pass by, the more frequently the lifting rod 2 is lifted, and the surface of the warning sign 6 is more likely to be covered with dust brought by the vehicles. At this time, the faster the air collecting box is inflated, the more frequent the blowing and cleaning.

[0043] When the lifting rod 2 is lifted, the conductive ball 10 falls and collides with the touch-pressure switch 23, so that the carbon fiber electric heating plate 22 is energized and works, heating the air in the air collecting box 19. On the one hand, the air expands due to heat, which can increase the kinetic energy of the air flow when it is blown out. On the other hand, it can melt the frost on the surface of the warning sign 6, reduce the weight of the lifting rod, and reduce the operating load of the motor 13; when there is no vehicle, the lifting rod 2 is in a horizontal state, and the conductive ball 10 will move to the end of the hollow tube 8 away from the touch-pressure switch 23, so that the carbon fiber electric heating plate 22 is powered off, reducing costs.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
