Description

Technical Field

[0001] This utility model relates to the field of automotive electronics technology, and in particular to a domain controller for automobiles with an anti-collision structure. Background Technology

[0002] It can integrate and manage multiple electronic control units, process sensor data and control vehicle functions. Automotive domain controllers with anti-collision structures are usually installed in collision-prone areas such as the front compartment. They form a buffer cavity through components such as body longitudinal beams, front frame, anti-collision beams, and brackets to enhance the ability to resist initial deformation in frontal collisions, protect the domain controller and wiring harness from squeezing and impact, and ensure that collision data can be smoothly transmitted to the central controller.

[0003] The domain controller is connected to sensors such as vehicle cameras and radar. It receives image data of objects in front acquired by the camera and point cloud data acquired by the radar. By fusing these data, it calculates the time distance between the vehicle in front and the vehicle itself. Combined with the vehicle's speed data, it generates proximity data between the vehicle and the vehicle in front. If the time distance between the vehicle and the vehicle in front is less than a preset threshold and continues to decrease, the domain controller will determine that a collision may occur. It will then control the vehicle warning unit to issue a warning message to remind the driver to take measures, or directly control the vehicle's braking system to perform automatic braking and other operations to avoid or mitigate collision damage.

[0004] In existing technologies, domain controllers are typically fixed inside the vehicle in a relatively simple manner. However, some domain controllers lack adequate shock absorption protection measures, making it difficult to dampen or prevent collisions during operation. This increases the risk of hardware damage. If the domain controller is subjected to vibration for a long time, it will cause internal components to shake, further increasing the risk of damage to these components and reducing the domain controller's lifespan. Therefore, a collision-resistant automotive domain controller with an anti-collision structure is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a domain controller for automobiles with an anti-collision structure, aiming to improve the problem that it is not easy to dampen and prevent collisions in the existing domain controller, thereby increasing the risk of hardware damage within the device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A domain controller for automobiles with an anti-collision structure includes a protective shell, characterized in that: a controller body is fixedly connected inside the protective shell; a buffer pad is fixedly connected outside the controller body; a telescopic rod is fixedly connected to the bottom of the protective shell; a spring is sleeved on the outside of the telescopic rod; a bracket is fixedly connected to the bottom of the telescopic rod; a hydraulic cylinder is fixedly connected to the top of the bracket; a rubber plug is slidably connected inside the hydraulic cylinder; a hydraulic rod is fixedly connected inside the rubber plug; two oil reservoirs are opened inside the hydraulic cylinder; and a quick-release assembly is fixedly connected inside the bracket.

[0008] As a further description of the above technical solution:

[0009] The quick-release assembly includes a base plate, with multiple rotating rods rotatably connected inside the base plate, multiple pads fixedly connected inside the base plate, a spring fixedly connected to the left side of each pad, a slider slidably connected inside each rotating rod, a turntable fixedly connected to the top of each rotating rod, and a lever fixedly connected to the outside of the turntable.

[0010] As a further description of the above technical solution:

[0011] The hydraulic cylinder has multiple oil guide ports inside, and the oil guide ports are located outside the oil storage tank.

[0012] As a further description of the above technical solution:

[0013] The top of the hydraulic rod is fixedly connected to the bottom of the protective shell, and the top of the base plate is fixedly connected to the bottom of the bracket;

[0014] As a further description of the above technical solution:

[0015] The base plate has a rotating groove inside, and the rotating rod is rotatably connected to the inside of the rotating groove.

[0016] As a further description of the above technical solution:

[0017] The rotating rod has a groove inside, and the slider is slidably connected to the inside of the groove.

[0018] As a further description of the above technical solution:

[0019] The rotating rod is externally rotatably connected to the inside of the bracket, and the second spring is externally slidably connected to the inside of the slide groove;

[0020] As a further description of the above technical solution:

[0021] The top of the first spring is fixedly connected to the bottom of the protective shell, and the bottom of the first spring is fixedly connected to the top of the bracket.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the buffer pad inside the protective shell absorbs part of the collision force generated by the controller body. The protective shell squeezes the hydraulic rod at the bottom of the protective shell, and the hydraulic rod squeezes downward, thereby causing the rubber plug to squeeze the liquid in the hydraulic cylinder. The liquid enters the oil storage tank through the oil guide port. The liquid entering the oil storage tank causes the gas to be compressed. The gas then uses the stored force to squeeze the liquid back, thereby achieving the effect of shock absorption and buffering. The base plate is vibrated, causing the bracket to shake, thereby causing the spring to rebound after being squeezed, thereby reducing part of the vibration and collision force, thus achieving the effect of shock absorption and collision prevention.

[0024] 2. In this utility model, when the equipment needs to be disassembled, by moving the lever, the lever rotates and drives the turntable to rotate. The turntable moves and drives the rotating rod to rotate in the rotating groove. The rotation of the rotating rod causes the slider to be squeezed, thereby squeezing the second spring into the groove. When the rotating rod rotates 90 degrees, the slider is squeezed into the groove, so that the rotating rod can be taken out from the bottom plate, achieving the effect of quick disassembly.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 2 and Figure 3 This utility model provides an embodiment comprising a protective shell 1, which serves as a protective frame and provides a physical barrier for the internal controller body 2. A buffer pad 3 is fixedly connected to the outside of the controller body 2. When an external impact force is transmitted to the protective shell 1, the buffer pad 3 initially absorbs the impact force. Furthermore, the buffer pad 3's cushioning effect reduces the direct impact of the impact force on the controller body 2, effectively protecting it. A telescopic rod 4 is fixedly connected to the bottom of the protective shell 1, and a spring 5 is sleeved on the outside of the telescopic rod 4. When the protective shell 1 is subjected to a downward impact force, the telescopic rod 4 contracts downward under the spring 5, causing the spring 5 to be compressed and elastically deformed. The elastic restoring force of the spring 5 and the telescopic movement of the telescopic rod 4 further buffer the impact force, reducing the vibration experienced by the protective shell 1 and its internal controller body 2. The telescopic rod 4 has a fixed support 6 at its bottom and a hydraulic cylinder 7 at its top. A rubber plug 8 is slidably connected inside the hydraulic cylinder 7, and a hydraulic rod 9 is fixedly connected inside the rubber plug 8. Two oil reservoirs 10 are located inside the hydraulic cylinder 7. When an impact force is transmitted to the support 6, the force is transmitted to the hydraulic cylinder 7 through the support 6, pushing the hydraulic rod 9 to move the rubber plug 8 within the hydraulic cylinder 7. The sliding of the rubber plug 8 causes the hydraulic oil in the hydraulic cylinder 7 to flow between the two oil reservoirs 10, generating a damping force. This damping force, combined with the flow resistance of the hydraulic oil and the sliding resistance of the rubber plug 8, further absorbs the impact force and reduces the vibration amplitude of the protective shell 1. Furthermore, a quick-disassembly assembly is fixedly connected inside the support 6. Operating this assembly allows for convenient and rapid disassembly of the domain controller by staff, improving maintenance efficiency.

[0034] Reference Figure 3 and Figure 5The quick-release assembly includes a base plate 12, inside which multiple rotating rods 13 are rotatably connected. When it is necessary to disassemble the domain controller components, external force is applied to the rotating rods 13, causing them to rotate within the base plate 12. Through the rotation of the rotating rods 13, multiple pads 15 are fixedly connected inside the base plate 12. The pads 15 provide stable support and auxiliary limiting, and provide an installation position for the second spring 16. The second spring 16 is fixedly connected to the left side of the pad 15. The second spring 16 has good elastic recovery capability; when the rotating rods 13 rotate and drive the related components to move, the second spring 16 will be compressed or stretched. The extension generates deformation, and the elastic deformation of spring 16 absorbs the impact force during the movement. Then, the elastic restoring force of spring 16 returns the component to its initial position after disassembly or installation. A slider 17 is slidably connected inside the rotating rod 13. The slider 17 can slide axially inside the rotating rod 13. When the rotating rod 13 rotates, the slider 17 slides within it, thus locking or unlocking the connected component. A turntable 18 is fixedly connected to the top of the rotating rod 13, increasing the operating area and facilitating the application of external force. The operator manually operates the turntable 18, causing the rotating rod 13 to rotate synchronously. A lever 19 is fixedly connected to the outside of the turntable 18, further enhancing the convenience and flexibility of operation. Staff can rotate the turntable 18 by moving the lever 19, and then use the leverage force provided by the lever 19 to more easily rotate the rotating rod 13, thereby completing the disassembly and installation of the domain controller components.

[0035] Reference Figures 3 to 5 When encountering a collision or severe vibration, the impact force first acts on the protective shell 1. The hydraulic rod 9, fixedly connected to the bottom of the protective shell 1, drives the rubber plug 8 to slide within the hydraulic cylinder 7. The sliding of the rubber plug 8 causes the hydraulic oil in the hydraulic cylinder 7 to flow between the oil reservoir 10 and the hydraulic cylinder 7 through the oil guide port 11. The damping force generated by the flow of hydraulic oil then achieves the purpose of buffering the impact and reducing the vibration amplitude of the protective shell 1. At the same time, the spring 5 between the protective shell 1 and the bracket 6 is compressed or stretched, and the elastic deformation of the spring 5 helps to absorb the impact. To release energy, when the domain controller needs to be disassembled for maintenance, the operator moves the lever 19 on the outside of the turntable 18. The lever 19 drives the turntable 18 and the rotating rod 13 to rotate in the rotating groove 14 of the base plate 12. When the rotating rod 13 rotates, the slider 17 in its internal sliding groove 20 slides along the sliding groove 20 under the action of the spring 16. Then, the sliding of the slider 17 releases the lock on the bracket 6 and achieves the purpose of quick disassembly. The base plate 12 is fixedly connected to the bottom of the bracket 6, providing a stable operating base for quick disassembly of the components.

[0036] Working principle: When a collision occurs, the buffer pad 3 inside the protective shell 1 absorbs part of the collision force generated by the controller body 2. The protective shell 1 is then pressed by the hydraulic rod 9 at the bottom of the protective shell 1. The hydraulic rod 9 is pressed downward, which drives the rubber plug 8 to squeeze the liquid inside the hydraulic cylinder 7. The liquid is squeezed and enters the oil storage tank 10 through the oil guide port 11 at the bottom of the hydraulic cylinder 7. Because the liquid enters the hydraulic cylinder 7, the gas inside the oil storage tank 10 is compressed. After the liquid squeezes the gas in the oil storage tank 10 in an instant, the gas uses the stored force to squeeze the liquid back, achieving the effect of shock absorption and buffering. At the same time, the bracket 6 guides the force to the spring 5 on the bracket 6. The base plate 12 is vibrated, causing the bracket 6 to shake. The bracket 6 is squeezed and shakes, which in turn squeezes the spring 5. After being squeezed, the spring 5 rebounds, thereby reducing some of the vibration and collision force, thus achieving the effect of shock absorption and collision prevention.

[0037] When disassembly of the equipment is required, by moving the lever 19, the lever 19 rotates and drives the turntable 18 to rotate. The movement of the turntable 18 drives the rotating rod 13 to rotate within the rotating groove 14. The rotation of the rotating rod 13 compresses the slider 17, thereby squeezing the spring 16 into the groove 20. When the rotating rod 13 rotates 90 degrees, the slider 17 is squeezed into the groove 20, allowing the rotating rod 13 to be removed from the base plate 12, achieving the effect of quick disassembly.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
