Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] Reference Figures 1-7 Figures 1-7 , a new type of electric vehicle ranging and braking device, includes a housing 1. One side of the housing 1 is fixedly connected with a side housing 2. The inner wall of the side housing 2 is fixedly connected with a driving motor 3. The output end of the driving motor 3 is fixedly connected with a rotating rod. One side of the rotating rod is fixedly connected with a push plate 4. The push plate 4 is arranged on the inner wall of the housing 1. The inner wall of the housing 1 is fixedly connected with a round shaft 8. Both sides of the round shaft 8 are rotatably connected with brake pads 5. The push plate 4 is arranged between the two groups of brake pads 5. The inner wall of the brake pad 5 is fixedly connected with a mounting block 6. A first spring 7 is fixedly connected between the two groups of mounting blocks 6. An installation groove 9 is opened at the bottom of the housing 1. The inner wall of the installation groove 9 is provided with a discharge component for discharging tiny particles in the housing 1. One side of the side housing 2 is provided with a monitoring component for monitoring obstacles ahead.

[0026] To solve the problem that it is easy to cause safety hazards during the braking of electric vehicles, when the electric vehicle is running, the battery inside the electric vehicle can drive the hub to rotate, thereby driving the battery vehicle to run. When braking is required, the monitoring component can be used to detect obstacles ahead. When an obstacle is detected, the driving motor 3 can be driven to drive the rotating rod to rotate. When the rotating rod rotates, it will drive the push plate 4 on one side to rotate. When the push plate 4 rotates, it will push the two groups of brake pads 5 on both sides to rotate to one side. The bottom of the two groups of brake pads 5 is rotatably connected to the round shaft 8. Therefore, the two groups of brake pads 5 will move to both sides until the brake pads 5 fit the inner wall of the housing 1, thus completing the operation of early braking, facilitating the electric vehicle to decelerate in advance, reducing the danger of driving. When the two groups of brake pads 5 move, they will drive the discharge component to operate, and the tiny particles generated in the housing 1 can be intermittently discharged, which is also beneficial to reducing the high temperature generated by the friction of the brake pads 5 and maintaining the effectiveness of the brake pads 5 in working. When the brake is not needed, the driving motor 3 can drive the push plate 4 to reset, and the two groups of first springs 7 can pull the two groups of brake pads 5 to reset.

[0027] Reference Figures 3-4 Figures 3-4 , the discharge component includes a gear 10. The gear 10 is rotatably connected to the inner wall of the installation groove 9. One side of the gear 10 is engaged with a first rack 11. The top of the first rack 11 is fixedly connected with an arc-shaped plate 12. The arc-shaped plate 12 is arranged at the bottom of the brake pad 5. The bottom of the housing 1 is fixedly connected with an installation frame 13. The bottom of the first rack 11 extends into the inner wall of the installation frame 13. The bottom of the first rack 11 is fixedly connected with a bottom plate 14. The bottom of the bottom plate 14 is fixedly connected with a second spring 15. The second spring 15 is fixedly connected to the inner wall of the installation frame 13. The bottom of the gear 10 is engaged with a second rack 16. One side of the second rack 16 is fixedly connected with a closing block 17. The bottom of the housing 1 is provided with a bottom opening 18. The closing block 17 is arranged on the inner wall of the bottom opening 18.

[0028] When the brake pad 5 moves to one side, it will push the arc-shaped plate 12 at the bottom downward. When the arc-shaped plate 12 moves downward, it will drive the first rack 11 and the bottom plate 14 at the bottom to move downward together. When the bottom plate 14 moves downward, it will squeeze the second spring 15, and when the first rack 11 moves downward, it will drive the gear 10 to rotate. When the gear 10 rotates, it will drive the second rack 16 to move to one side. When the second rack 16 moves to one side, it will drive the closing block 17 to move together. When the two groups of closing blocks 17 move to both sides, they will open the bottom opening 18. After the bottom opening 18 is opened, the tiny particulate matters remaining in the housing 1 can be discharged to prevent the particulate matters from accumulating inside the housing 1. When the bottom opening 18 is opened, air flow will flow into the housing 1, thereby providing a heat dissipation effect for the brake pad 5 and preventing the brake pad 5 from overheating during operation.

[0029] Referring to Figures 6-7 , the monitoring component includes a transmission line 20. The transmission line 20 is fixedly connected to one side of the side shell 2. A processing module 23 is fixedly connected to the inner wall of the side shell 2. One side of the processing module 23 is connected to the transmission line 20, and the other side of the processing module 23 is connected to the drive motor 3. One end of the transmission line 20 is fixedly connected to a mounting plate 21. The mounting plate 21 is arranged at the front of the electric vehicle. An ultrasonic sensor 22 is fixedly connected to one side of the mounting plate 21. A loudspeaker 24 is fixedly connected to one side of the side shell 2. The loudspeaker 24 is connected to the processing module 23 through a circuit.

[0030] By arranging the mounting plate 21 at the front of the vehicle, when the electric vehicle is running, the ultrasonic sensor 22 arranged on the mounting plate 21 can be used to detect obstacles in front of the electric vehicle. When an obstacle is detected, the signal will be transmitted to the processing module 23 through the transmission line 20, and the processing module 23 will process the signal through the microcontroller arranged inside. The microcontroller is of the STM32 series. The microcontroller can transmit instructions to the drive motor 3 through a circuit, so that the drive motor 3 drives the push plate 4 to rotate to brake the electric vehicle. At the same time, the processing module 23 can also start the loudspeaker 24 arranged on one side. The loudspeaker 24 generates sound to remind the driver, which is beneficial to ensuring driving safety.

[0031] Referring to Figure 1 , a fixing sleeve 26 is sleeved on the outer wall of the transmission line 20. The fixing sleeve 26 is in a cylindrical shape.

[0032] By arranging the fixing sleeve 26 on the outer wall of the transmission line 20, it is beneficial to install the transmission line 20 at a specified position on the electric vehicle through the fixing sleeve 26.

[0033] Referring to Figure 7, one side of the mounting plate 21 is fixedly connected with mounting rings 25, and there are two groups of the mounting rings 25, which are symmetrically distributed on both sides of the mounting plate 21.

[0034] By arranging the mounting rings 25 on both sides of the mounting plate 21, it is beneficial to use screws to pass through the mounting rings 25 to fix the mounting plate 21 at the front of the electric vehicle.

[0035] Refer to Figure 4 , one side of the closing block 17 is fixedly connected with a sealing gasket 27, the material of the sealing gasket 27 is rubber, a sliding groove is opened at the bottom of the mounting groove 9, the bottom of the second rack 16 is fixedly connected with a sliding block 19, and the sliding block 19 is slidably connected to the inner wall of the sliding groove.

[0036] By arranging the sealing gasket 27 on one side of the closing block 17, when the two closing blocks 17 are closed, it is convenient to improve the sealing performance of the bottom opening 18 through the sealing gasket 27. By arranging the sliding block 19 at the bottom of the second rack 16, when the second rack 16 moves, the sliding block 19 can be driven to slide in the sliding groove, and the movement track of the second rack 16 can be limited.

[0037] Working principle: To solve the problem of potential safety hazards easily caused during the braking of electric vehicles, when the electric vehicle is running, the battery inside the electric vehicle can drive the hub to rotate, thereby driving the electric vehicle forward. When the electric vehicle is running, the ultrasonic sensor 22 installed on the mounting plate 21 is used to detect obstacles in front of the electric vehicle. When an obstacle is detected, the signal will be transmitted to the processing module 23 through the transmission line 20, and the processing module 23 will process the signal through the microcontroller set inside. The microcontroller is of the STM32 series. The microcontroller can transmit instructions to the drive motor 3 through a circuit, so that the drive motor 3 drives the push plate 4 to rotate. When the push plate 4 rotates, it will push the two brake pads 5 on both sides to rotate to one side. The bottoms of the two brake pads 5 are rotatably connected to the round shaft 8. Therefore, the two brake pads 5 will move to both sides until the brake pads 5 fit against the inner wall of the housing 1, thus completing the operation of early braking, facilitating the electric vehicle to decelerate in advance, reducing the driving risk. At the same time, the processing module 23 can also activate the speaker 24 set on one side. The speaker 24 generates sound to remind the driver, which is beneficial to ensuring driving safety. When the brake pad 5 moves to one side, it will push the arc-shaped plate 12 at the bottom downward. When the arc-shaped plate 12 moves downward, it will drive the first rack 11 and the bottom plate 14 at the bottom to move downward together. When the bottom plate 14 moves downward, it will compress the second spring 15. When the first rack 11 moves downward, it will drive the gear 10 to rotate. When the gear 10 rotates, it will drive the second rack 16 to move to one side. When the second rack 16 moves to one side, it will drive the closing block 17 to move together. When the two closing blocks 17 move to both sides, they will open the bottom opening 18. After the bottom opening 18 is opened, the tiny particulate matters remaining in the housing 1 can be discharged to prevent the particulate matters from accumulating inside the housing 1. When the bottom opening 18 is opened, air flow will flow into the housing 1, thereby providing a heat dissipation effect for the brake pads 5 to prevent the brake pads 5 from overheating during operation. When the brakes are not needed, the drive motor 3 can drive the push plate 4 to reset, and the two first springs 7 can pull the two brake pads 5 to reset. By setting the fixing sleeve 26 on the outer wall of the transmission line 20, it is beneficial to install the transmission line 20 at the specified position on the electric vehicle through the fixing sleeve 26. By setting the mounting rings 25 on both sides of the mounting plate 21, it is beneficial to use screws to pass through the mounting rings 25 to fix the mounting plate 21 at the front of the electric vehicle.
