[0001] The present invention relates to the technical field of vehicle braking, and in particular to an automatic braking device for active braking of a vehicle. Background Art

[0002] The vehicle's automatic braking system is a core component of the intelligent driving safety system. By integrating sensor perception, data processing, and brake execution technology, it actively intervenes in braking when there is a risk of collision, improving driving safety. However, existing vehicle automatic braking systems have some shortcomings, such as: Application number: CN202010303685.2 is a vehicle driving brake device with auxiliary braking function. The device actively uses the anti-lock braking mechanism to achieve tire braking, improve the controllability of the vehicle, and avoid vehicle rollover, which may cause traffic accidents and driver injuries. Compared with traditional braking systems, the present invention has excellent braking ability and high braking safety. However, in actual use, the device only relies on a single set of brake equipment to perform braking operations. This single braking structure may cause uneven force on the vehicle during braking, thereby causing the problem of insufficient braking stability.

[0003] Therefore, we propose an automatic braking device for active braking of a vehicle in order to solve the above-mentioned problems. Summary of the Invention

[0006] By driving the brake mechanism and the oil delivery mechanism at the same time through the driving mechanism, when the brake seat is in contact with the heat dissipation holes on the outside of the brake disc to perform the braking operation, the oil delivery mechanism will also transfer the brake oil to the brake pad, so that the brake pad can brake the top of the brake disc, thereby enabling the brake seat and the brake pad to brake the brake disc at the same time in two directions, making the device more stable during the braking operation.

[0007] As a preferred technical solution of the present invention, the protective shell is fixedly connected to the base plate, and the driving mechanism is fixedly connected to the base plate, and the driving mechanism includes a servo motor, the driving end of the servo motor is connected to a first sprocket, and a chain is engaged on the outside of the first sprocket, and the other end of the chain is engaged with a second sprocket.

The vehicle control module can continuously power the servo motor 5 through the vehicle power supply module, thereby completing the braking process of automatic braking.

[0028] Working principle: When the automatic braking device for active braking of a vehicle is used, the driving mechanism first drives the brake mechanism and the oil delivery mechanism to operate simultaneously, so that the brake seat 12 is fitted and fixed to the outer side of the brake disc 4, so that the outer side of the second brake fixing plate 403 in the brake disc 4 is fitted and fixed to the brake seat 12, and the fixing column 13 inside the brake seat 12 is fitted and fixed to the heat dissipation hole 404 in the second brake fixing plate 403, and at the same time, the friction ring 14 is also fitted and slid with the friction groove 405, so as to limit the brake seat 12, and the bending spring damper 16 on the left side of the brake seat 12 is also The torsional force exerted on the brake seat 12 itself is absorbed and rebounded to reset, thereby increasing the torsional resistance of the brake seat 12, and at the same time, the oil delivery mechanism also transmits the brake oil to the brake pad 25, so that the brake pad 25 is fitted to the top of the brake disc 4, so that the brake mechanism and the brake pad 25 brake the brake disc 4 in two directions; When the driving mechanism is running, the vehicle control module will drive the driving end of the servo motor 5 to rotate, so that the servo motor 5 drives the first sprocket 6 to rotate, so that the first sprocket 6 drives the second sprocket 8 to rotate through the chain 7, and the second sprocket 8 drives the first threaded shaft 9 to rotate, so that the first threaded shaft 9 drives the first threaded sleeve 10 and the clamping plate 11 to move, so that the clamping plate 11 drives the brake seat 12 to move through the fixing ring 29, and because the left end of the brake seat 12 is provided with a connecting damper 17 and a fixing bolt 30 connected to the protective shell 1, the brake seat 12 is limited by the connecting damper 17 when it moves, so that the brake seat 12 can be more stable when it is fitted and fixed with the brake disc 4; When the second sprocket 8 rotates, the second sprocket 8 drives the second threaded shaft 18 to rotate, thereby causing the second threaded shaft 18 to drive the second threaded sleeve 19 to move. Since the second threaded sleeve 19 is slidably connected to the outer side of the hydraulic cylinder 21 through the convex groove, the second threaded sleeve 19 can be limited to prevent it from rotating. The second threaded sleeve 19 drives the sealing gasket 20 to move, so that the sealing gasket 20 exerts pressure on the inside of the hydraulic cylinder 21, so that the brake oil inside the hydraulic cylinder 21 is transmitted through the oil pipe 24. When the oil delivery pipe 24 transmits the brake oil, it will transmit the brake oil to the four groups of hydraulic cylinders 27, thereby increasing the brake oil inside the hydraulic cylinders 27, causing the hydraulic cylinders 27 to push the hydraulic seat 28 to move, thereby causing the hydraulic seat 28 to push the bonding sheet 26 to move, so that the two groups of bonding sheets 26 clamp the top of the brake disc 4, so that the top of the brake disc 4 is bonded and fixed by the bonding sheet 26, and the outer surface of the brake disc 4 is bonded and fixed by the brake seat 12 in the brake mechanism, so that the device can brake the brake disc 4 simultaneously from both sides, and when the servo motor 5 rotates in the opposite direction, it will cause the second threaded shaft 18 to rotate in the opposite direction, and the second threaded sleeve 19 will drive the sealing gasket 20 to push, thereby changing the sealed space inside the hydraulic cylinder 21, and transmitting the brake oil inside the hydraulic cylinder 27 to the inside of the hydraulic cylinder 21 through the oil delivery pipe 24; When the brake mechanism and the brake pad 25 release the brake disc 4, the brake disc 4 is in an overheated state, and the tire 3 will drive the brake disc 4 to rotate again, so that the first brake fixing plate 401 and the second brake fixing plate 403 can dissipate heat through the air grooves and heat dissipation holes 404 formed by the heat sink 402, thereby preventing the brake disc 4 from overheating during use.
