[0005] This utility model provides an active obstacle-blocking device for high-speed obstacles under a vehicle, which can solve the technical problem that flying debris from car accidents or other causes can easily damage the vehicle chassis. The technical solution is as follows: In a first aspect, embodiments of this utility model provide an active obstacle-blocking device for high-speed obstacles under a vehicle, comprising: an underbody protection plate, multiple rotating devices, multiple blocking devices, and multiple locking devices. The underbody protection plate is installed on the vehicle chassis, and the multiple blocking devices are respectively installed at different positions on the bottom of the underbody protection plate; The plurality of the aforementioned blocking devices are respectively disposed between the plurality of the aforementioned rotating devices and the underbody protection plate; The locking device is located on the rotating device and the underbody protection plate.

[0006] Optionally, each of the rotating devices includes a support base, a rotating shaft, and a guard plate. The support base is disposed on the undercarriage guard plate, and the guard plate is rotatably connected to the support base via the rotating shaft.

[0007] Optionally, each of the barrier devices includes two connecting seats and a barrier net. The two connecting seats are respectively disposed on the barrier guard plate and the vehicle underbody guard plate, and the two ends of the barrier net are respectively fixed to the two connecting seats.

[0008] Optionally, each of the locking devices includes an electromagnet and a magnetic block, which are respectively disposed on the underbody protection plate and the barrier plate.

[0013] Optionally, the barrier net is a flexible mesh structure.

[0014] Optionally, the thickness of the barrier plate is 1 to 2 cm.

[0015] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following: This utility model, through the cooperation of a rotating device, a blocking device, and a locking device, can effectively block some objects that may damage the chassis of a car. The overall structure is relatively lightweight and does not add too much weight. The locking device can keep the blocking device and the rotating device close to the underbody protection plate when there is no need to block obstacles, thus preserving the space under the car to the maximum extent.

[0016] The guard plate rotates around a pivot point. This structure ensures that when there is no need to block obstacles, the guard plate will be as close as possible to the underbody protection plate of the vehicle under the action of the locking device and the pivot point.

[0017] When the locking mechanism is unlocked, the barrier plate will rotate downwards under the action of gravity. At this time, the barrier net will be fully opened, blocking the rapidly approaching debris. Since the barrier net is a flexible structure, it can absorb the impact force through deformation when encountering debris.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Figure 1 This is a three-dimensional structural diagram of the overall structure provided in this embodiment of the utility model; Figure 2 This is a three-dimensional structural schematic diagram of the rotating device provided in an embodiment of the present utility model; Figure 3 This is a cross-sectional schematic diagram showing the connection relationship between the rotating shaft and the limiting ring provided in an embodiment of this utility model. For example... Figures 1 to 3 As shown, this utility model embodiment provides an active obstacle-blocking device for high-speed obstacles under a vehicle, aiming to solve the technical problem of debris flying around in car accidents or other causes, which can easily damage the vehicle chassis. It includes: an underbody protection plate 1, multiple rotating devices 2, multiple blocking devices 3, and multiple locking devices 4.

[0025] The underbody protection plate 1 is installed on the vehicle chassis, and multiple blocking devices 3 are respectively installed at different positions on the bottom of the underbody protection plate 1. The multiple blocking devices 3 are respectively installed between multiple rotating devices 2 and the underbody protection plate 1, and the locking device 4 is installed on the rotating device 2 and the underbody protection plate 1.

[0026] In this embodiment of the utility model, the underbody protection plate 1 is installed on the vehicle chassis, and multiple blocking devices 3 are respectively installed at different positions on the bottom of the underbody protection plate 1. Specifically, the multiple blocking devices 3 can be respectively installed at the front, rear, left, and right sides of the vehicle, which can block debris flying towards the four directions of the vehicle, thereby providing sufficient protection for the vehicle chassis. The multiple blocking devices 3 are respectively installed between the multiple rotating devices 2 and the underbody protection plate 1. In specific implementation, the underbody protection plate 1 supports one end of the rotating device 2, and the other end of the rotating device 2 is connected to the underbody protection plate 1 through the blocking device 3. Since the blocking device 3 is mostly a flexible structure, in actual use, the rotating device 2 will rotate around the rotating shaft 22 as the rotation center under the action of gravity. Due to the action of the blocking device 3, the rotation angle of the rotating device 2 will be limited to avoid the rotating device 2 from completely contacting the ground. In addition, when an external force is applied to the blocking device 3, the blocking device 3 will deform, which will drive the rotating device 2 to rotate in the opposite direction. The rotating device 2 can also overcome gravity and consume some of the impact force. The locking device 4 is installed on the rotating device 2 and the underbody protection plate 1. In practice, to lock the rotating device 2, the driver must get out of the vehicle and energize the electromagnet 41, then hold the rotating device 2 in their hand to make the electromagnet 41 and the magnetic block 42 on the locking device 4 come into contact. At this point, the rotating device 2 will be firmly locked to the underbody protection plate 1. In summary, through the combination of the rotating device 2's own structure and the blocking device 3, it does not occupy too much space under the vehicle while providing a good blocking effect. Furthermore, the rotating device 2, blocking device 3, and locking device 4 can all be directly installed on the underbody protection plate 1, thus not significantly altering the existing vehicle structure and making installation convenient.

[0027] Optionally, each rotating device 2 includes a support base 21, a rotating shaft 22, and a barrier plate 23. The support base 21 is mounted on the underbody protection plate 1, and the barrier plate 23 is rotatably connected to the support base 21 via the rotating shaft 22. Exemplarily, in this embodiment of the invention, the specific lengths of the support base 21, rotating shaft 22, and barrier plate 23 need to be designed according to the actual length of the vehicle's underbody. Limiting plates are provided at both ends of the support base 21 to limit the rotation shaft 22 and reduce its lateral sway. The support base 21 and rotating shaft 22 can also be replaced with other structures, as long as it ensures that the barrier plate 23 can rotate smoothly.

[0028] Optionally, each barrier device 3 includes two connecting seats 31 and a barrier net 32. The two connecting seats 31 are respectively disposed on the barrier guard plate 23 and the undercarriage guard plate 1, and the two ends of the barrier net 32 ​​are respectively fixed to the two connecting seats 31. Exemplarily, in this embodiment of the present invention, since the barrier net 32 ​​is a mesh structure, if it is directly installed on the undercarriage guard plate 1 and the barrier guard plate 23, the difference in material and structure will increase the difficulty of installation, and the stability between the barrier net 32 ​​and the undercarriage guard plate 1 and the barrier guard plate 23 cannot be guaranteed. Therefore, it is necessary to set two connecting seats 31 to fix the barrier net 32. In this way, during installation, only bolts or other structures are needed to set the two connecting seats 31 on the undercarriage guard plate 1 and the barrier guard plate 23 respectively to complete the fixation of the barrier net 32, which simplifies the installation process and improves the stability of the barrier device 3.

[0029] Optionally, each locking device 4 includes an electromagnet 41 and a magnetic block 42, which are respectively mounted on the underbody protection plate 1 and the barrier plate 23. Exemplarily, in this embodiment of the invention, the cooperation of the electromagnet 41 and the magnetic block 42 ensures a relatively stable magnetic attraction effect and improves safety. Since the release action is achieved simply by de-energizing the electromagnet 41 in conjunction with gravity, it is more reliable than a dual-electromagnet solution. Furthermore, the wiring is simpler; only the cable and control switch need to be connected to the electromagnet 41. Since the electromagnet 41 is directly mounted on the underbody protection plate 1 with minimal movement, the cable is not subjected to pulling during movement, thus extending the cable's lifespan and effectively saving costs.

[0030] Optionally, the support base 21 has a rotating groove adapted to the rotating shaft 22, and the rotating shaft 22 is located in the rotating groove and movably connected to the rotating groove. Exemplarily, in this embodiment of the present invention, the rotating groove is coaxial with the rotating shaft 22, and the rotating groove can partially limit the rotation of the rotating shaft 22, improving the stability of the rotating shaft 22. When the rotating shaft 22 rotates, it drives the barrier plate 23 to rotate together. Through the cooperation of the rotating groove and the limiting ring 24, it can provide support for the rotating shaft 22. When the locking mechanism 4 is locked, the support base 21 provides support for one end of the barrier plate 23 through the rotating shaft 22, and the other end of the barrier plate 23 is supported by the locking mechanism 4. At this time, the barrier plate 23 is in a fully limited state. When unlocked, both ends of the barrier plate 23 are supported by the support base 21 and the blocking device 3, respectively.

[0031] Optionally, the support base 21 is provided with multiple limiting rings 24, and the barrier plate 23 is provided with multiple connecting blocks 25 on the side near the rotating shaft 22. Exemplarily, in this embodiment of the invention, the limiting rings 24 are coaxial with the rotating shaft 22. Furthermore, the limiting rings 24 provide support for the rotating shaft 22 and, in conjunction with the connecting blocks 25, limit the barrier plate 23. The barrier plate 23, with multiple limiting rings 24 limiting multiple connecting blocks 25, achieves a first limiting effect on the barrier plate 23 through the cooperation of the limiting rings 24 and connecting blocks 25. Then, in conjunction with the limiting plate on the support base 21, it limits the rotating shaft 22, thereby achieving a second limiting effect on the barrier plate 23. This effectively improves the stability of the rotating shaft 22. In addition, a certain distance is maintained between the limiting plate and the rotating shaft 22; the limiting plate only functions when the limiting effect of the connecting blocks 25 and the limiting rings 24 fails.

[0032] Optionally, the other end of the multiple connecting blocks 25 is fixed to the rotating shaft 22. For example, in this embodiment of the present invention, the purpose of setting multiple connecting blocks 25 is to connect the rotating shaft 22 and the barrier plate 23. Both ends of each connecting block 25 are connected to the rotating shaft 22 and the barrier plate 23 respectively. This connection method can ensure that the failure of a single connecting block 25 will not affect the overall connection too much.

[0033] Optionally, multiple limiting rings 24 and multiple connecting blocks 25 are arranged alternately. For example, in this embodiment of the present invention, the alternating arrangement of limiting rings 24 and connecting blocks 25 can disperse external forces and reduce the force acting on a single connecting block 25. Specifically, there is a limiting ring between every two connecting blocks 25, and the limiting ring and the connecting block 25 are in a movable connection relationship.

[0034] Optionally, the barrier net 32 ​​is a flexible mesh structure. The material of the barrier net 32 ​​is one of high-strength nylon, high-strength polyethylene fiber, or Kevlar fiber. For example, in this embodiment of the present invention, if high-strength nylon is used to make the barrier net 32, it can ensure high strength and is relatively inexpensive. If you want to pursue extreme lightweight and impact resistance, you can use high-strength polyethylene fiber, but it needs to be kept away from high-temperature components. If you need to deal with sharp fragments, you can use Kevlar fiber. In addition, the specific material of the barrier net 32 ​​can be specially designed according to actual needs. The barrier net 32 ​​made of high-strength nylon, high-strength polyethylene fiber, or Kevlar fiber has good flexibility and can also take good toughness.

[0035] Optionally, the thickness of the barrier plate 23 is 1 to 2 cm, and the material of the barrier plate 23 is one of aluminum alloy, carbon fiber or titanium alloy. For example, in this embodiment of the present invention, since the barrier plate 23 needs to have a certain rigidity, when the magnetic block 42 on the barrier plate 23 is magnetically attracted to the electromagnet 41, it will also clamp part of the barrier net 32. This method can ensure that the barrier net 32 ​​will not drift when the device is not used, so as to improve the overall stability. The barrier plate 23 made of materials such as aluminum alloy, carbon fiber or titanium alloy can ensure support while having a low density.

[0036] In addition, this device is directly connected to the car chassis. Only a control switch needs to be installed on the car. Then, the control switch is controlled by the car's existing pedestrian radar, driving radar and central control. This further controls the energization of the electromagnet 41. Specifically, the power supply end of the electromagnet 41 is electrically connected to the power supply end of the control switch, the power supply end of the control switch is electrically connected to the power supply end of the vehicle's power supply device, and the control end of the control switch is electrically connected to the central control.

[0037] In summary, this device can be controlled using the existing pedestrian and vehicle radars and the existing central control system on the vehicle. A rotating device 2, a blocking device 3, and a locking device 4 are installed on the underbody protection plate 1. A cable for connecting the electromagnet 41 and a control switch are added. The control switch is connected to the vehicle system. The opening and closing of the control switch is controlled by the vehicle system to further control the energization and de-energization of the electromagnet 41.
