[0029] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1-Figure 5As shown, an embodiment of the utility model provides a smart parking lot collision alarm device, which is applied to parking spaces in a parking lot. The parking lot ground includes a plurality of rectangular parking planning lines 1, and a rectangular area surrounded by the parking planning lines 1 forms a parking space. One end of the parking planning lines 1 forms an entrance and exit end of the parking space, and a charging pile 2 is arranged at an end of the parking space away from the entrance and exit end. The smart parking lot collision alarm device includes a blocking block 3, a blocking component, a pressure sensor 7, a buzzer and a controller 4;

[0031] There are two car blocks 3, which are arranged side by side at one end of the parking space away from the entrance and exit end thereof, and the two opposite inclined surfaces of the car blocks 3 face the charging pile 2 and the entrance and exit end of the parking space respectively, and the distance between the car block 3 and the entrance and exit end of the parking space is smaller than the distance between the charging pile 2 and the entrance and exit end of the parking space; the car block 3 is an isosceles trapezoidal block, and at least one pressure sensor 7 is installed on the top surface of each car block 3;

[0032] The blocking assembly includes a guide rail 11, a shift rod 12 and a driving mechanism. The guide rail 11 and the shift rod 12 correspond to each other one by one. An installation cavity 301 is provided inside the blocking block 3, and an opening is provided on the top surface thereof. The opening is connected to the installation cavity 301. At least one vertically arranged guide rail 11 is provided in the installation cavity 301 of the blocking block 3. A shift rod 12 is slidably installed on the guide rail 11. The driving mechanism is used to drive the shift rod 12 to slide along the guide rail 11 to extend or retract the installation cavity 301; the driving mechanism, the buzzer and the pressure sensor 7 are respectively connected to the controller 4 signal.

[0033] In this embodiment, for the convenience of description, the side close to the entrance and exit of the parking space is the front, and the side close to the charging pile 2 is the rear. Two blocking blocks 3 are installed near the charging pile 2 in the rear area of ​​the parking space to prevent vehicles from approaching the charging pile 2. Because the underground parking lot is dim, it is difficult for the owner who is reversing to effectively observe the charging pile 2 behind the car, so the owner will continue to reverse to the rear. In addition, due to the urging of other vehicles, the owner's reversing speed will increase, and the vehicle tires will first be blocked by the inclined surface in front of the blocking block 3, which plays a role in preventing the vehicle from approaching the charging pile 2 and avoiding collision between the vehicle and the charging pile 2. If the vehicle speed is relatively fast and the vehicle does not stop immediately, the vehicle tire will pass over the inclined surface in front of the stop block 3 and enter the top surface of the stop block 3, and then the pressure sensor 7 on the top surface of the stop block 3 is stressed and sends a pressure signal to the controller 4. The controller 4 controls the buzzer to alarm. At the same time, the controller 4 controls the driving mechanism to drive the shift lever 12 to slide along the guide rail 11 to extend out of the installation cavity 301. The shift lever 12 plays a role in blocking the vehicle, making it impossible for the vehicle to continue to reverse to the rear. When the owner of the vehicle who is reversing hears the alarm, he immediately steps on the brake and stops reversing to the rear, but drives forward, causing the vehicle to drive down from the stop block 3.

[0034] This can effectively prevent the car owner from colliding with the charging pile 2 during the reversing process, thus avoiding unnecessary losses.

[0035] As a preferred embodiment, in order to warn the reversing owner more clearly, a warning light is installed on the side of the charging pile 2 facing the block 3, and the warning light is connected to the controller 4 signal. When the vehicle tire drives to the upper surface of the block 3 and contacts the pressure sensor 7, the controller 4 receives the pressure signal sent by the pressure sensor 7, and the controller 4 controls the buzzer alarm and the warning light to turn on and flash at the same time, so that the owner can observe the flashing light behind him while hearing the alarm sound, so as to remind the owner in time that he can no longer continue to reverse to the rear. In addition, the buzzer and the warning light are set at the same time for dual alarm, so that when one of the alarm devices is damaged, the other alarm device can also work normally.

[0036] In addition, the warning light can also be installed on the side of the car block 3. Because the light in the underground parking lot is dim, even if the warning light is installed at a low position, the owner can observe the flashing light behind through the rearview mirror.

[0037] It should be noted that the charging pile 2 is usually installed behind the parking space and biased to one side of the parking space, that is, the charging pile 2 is not centrally arranged behind the parking space, because the charging port of the electric vehicle is basically on the side of the vehicle. In this way, when charging, it is more convenient for the owner to pick up the charging gun 201 and insert it into the charging port on the side of the electric vehicle for charging.

[0038] As a preferred embodiment, Figure 3 , Figure 4 and Figure 5 As shown, the car block 3 is an isosceles trapezoidal block, and the two inclined surfaces of the car block 3 face the front of the charging pile 2 and the parking space respectively. An opening is provided on the upper surface of the car block 3, and the opening is in the shape of a long strip, and the length direction of the opening is the same as the length direction of the car block 3. The opening is connected to the installation cavity 301, and a plurality of guide rails 11 are vertically installed in the installation cavity 301. The guide rails 11 are arranged in sequence along the depth direction of the installation cavity 301, and a gear lever 12 is slidably installed on each guide rail 11, and the gear lever 12 is located in the opening of the car block 3. Among them, the installation cavity 301 of the car block 3 runs through the left and right sides of the car block 3, and the openings of the left and right sides are sealed with sealing plates, which play a role in preventing dust from entering.

[0039] Further, the driving mechanism includes a driving shaft 8, a plurality of rotating gears 802 and a driving device, wherein Figure 3As shown, both ends of the drive shaft 8 are respectively inserted into the mounting cavities 301 of the two blocking blocks 3, and a plurality of rotating gears 802 are respectively provided at both ends of the drive shaft 8. The rotating gears 802 and the shift rods 12 correspond one to one. The rotating gears 802 at both ends of the drive shaft 8 are respectively located in the mounting cavities 301 of the two blocking blocks 3, and a plurality of tooth blocks are provided on the side of the shift rod 12 away from the guide rail 11, and the tooth blocks are evenly arranged along the length direction of the shift rod 12. The rotating gears 802 are meshed with the tooth blocks on the corresponding shift rod 12, and the driving device is used to drive the drive shaft 8 to rotate around its own axis.

[0040] In this way, when the driving device drives the driving shaft 8 to rotate around its own axis, the driving shaft 8 drives multiple rotating gears 802 at both ends to rotate simultaneously. Since the rotating gears 802 are meshed with the tooth blocks on the corresponding gear rods 12, all the gear rods 12 can be driven to move upward or downward along the guide rail 11 at the same time to extend or retract into the installation cavity 301.

[0041] As a preferred embodiment, Figure 3 and Figure 4 As shown, the driving device includes a fixed gear 801, a rotating shaft, a driving gear 9 and a motor 10, wherein two fixed seats are fixedly installed on the ground between the two car blocks 3, the rotating shaft is rotatably installed between the two fixed seats, the fixed gear 801 is coaxially arranged on the driving shaft 8, the driving gear 9 is coaxially arranged on the rotating shaft, the driving gear 9 and the fixed gear 801 are meshed, the output end of the motor 10 is connected to one end of the rotating shaft to drive the rotating shaft to rotate around its axis, the motor 10 is connected to the controller 4 signal, and the controller 4 controls the opening and closing of the motor 10.

[0042] The controller 4 controls the motor 10 to turn on, the motor 10 drives the shaft to rotate, and the shaft drives the driving gear 9 to rotate. Because the driving gear 9 and the fixed gear 801 are meshed, the fixed gear 801 and the driving shaft 8 can be driven to rotate. The driving shaft 8 rotates to drive all the rotating gears 802 to rotate synchronously.

[0043] It can be seen that the driving mechanism can simultaneously drive the shift rods 12 on the two vehicle blocks 3 to move, and the two vehicle blocks 3 can work.

[0044] Therefore, when the pressure sensor 7 on the top surface of the block 3 is subjected to the pressure exerted by the vehicle tire, the controller 4 controls the buzzer to alarm. At the same time, the controller 4 controls the motor 10 to drive the rotating shaft to rotate, and the rotating shaft drives the driving gear 9 to rotate. Because the driving gear 9 and the fixed gear 801 are meshed, the fixed gear 801 and the driving shaft 8 can be driven to rotate. The driving shaft 8 rotates to drive all the rotating gears 802 to rotate synchronously, thereby driving all the gear rods 12 to move upward along the guide rail 11 at the same time to extend out of the installation cavity 301, that is, the top end of the gear rod 12 is higher than the upper surface of the block 3, so as to block the vehicle and prevent it from continuing to move backward and colliding with the charging pile 2.

[0045] Optional, such as Figure 1 As shown, a protection box 6 is installed on the ground of the parking space, and the protection box 6 covers the motor 10, the fixed gear 801 and the driving gear 9 to protect these components and prevent dust from entering, while also reducing noise.

[0046] It should be noted that if Figure 4 As shown, the opening of the top surface of the block 3 is close to the rear of the block 3 , and a plurality of pressure sensors 7 are installed on the top surface of the block 3 . The plurality of pressure sensors 7 are arranged in sequence along the length direction of the block 3 .

[0047] As an optional embodiment, Figure 1 As shown, the controller 4 is installed on the side of the charging pile 2 facing the middle of the parking space, and a distance sensor 5 is installed on the side of the controller 4 pointing to the entrance and exit end of the parking space. The distance sensor 5 is connected to the controller 4 signal, and the distance sensor 5 is used to detect the distance between the vehicle and the charging pile 2. When the distance sensor 5 detects that the distance between the rear of the vehicle and the charging pile 2 reaches the set range, the controller 4 starts the buzzer and the warning light, and turns on the motor 10 to prevent the vehicle from continuing to reverse to the rear. In this way, there is no need to install a pressure sensor 7 on the block 3. The distance between the rear of the vehicle and the charging pile 2 is detected by the distance sensor 5. When the distance between the rear of the vehicle and the charging pile 2 reaches the set dangerous range, it indicates that the vehicle is likely to collide with the charging pile 2 if it continues to reverse. Therefore, the controller 4 starts the motor 10 to extend the gear lever 12 in the block 3 to immediately block the vehicle.
