The brake pedal assembly 4 is fixedly connected to one end of the traction assembly 3, such as Figure 6As shown, the brake pedal assembly 4 includes: a first bracket 41, a first locking shaft 42, a second bracket 43, and a second locking shaft 44. Specifically, the first bracket 41 is fixedly connected to the bottom of the original vehicle mechanical pedal, that is, the first position of the vehicle's mechanical pedal; and then the first locking shaft 42 is fixedly connected between the two side vertical plates of the first bracket 41 by bolts, and at the same time, a plurality of first locking holes 421 are opened in the middle position of the first locking shaft 42, and then the first locking holes 421 can be locked with the threaded sections at the second end position of the outer sleeve 32 of the traction rope in a one-to-one correspondence, and the number of the first locking holes 421 corresponds to the number of the traction ropes 31. Since the number of traction ropes 31 is two as a preferred embodiment in this embodiment, similarly, the number of the first locking holes 421 is two as a preferred embodiment in this embodiment; the second bracket 43 is fixedly connected to the front position of the original vehicle brake pedal, that is, the second position of the vehicle's mechanical pedal, and the second position is higher than the first position; threaded holes are provided at both ends of the second locking shaft 44, which can be rotatably placed in the middle position of the second bracket 43 by bolts.

The other end of the traction rope 31 is fixedly connected to the second locking hole 441.

[0051] In this embodiment, when the drive motor 211 rotates, the drive execution unit 23 rotates, and during the rotation process, the traction rope 31 is pulled and wound in the U-shaped receiving groove 2313. As the traction rope 31 is tightened, it pulls the second lock shaft 44 downward, and at the same time pulls the original vehicle brake pedal downward, thereby braking the vehicle. When it is necessary to release, the drive motor is reversed to release the traction rope 31, and the original vehicle brake pedal relies on its own internal reaction force to return to its original position. When the driver needs to drive, he steps on the brake pedal with his foot. Since the traction rope 31 can bend naturally, it will not affect the driver's normal driving operation.

[0052] Furthermore, a reset hole is provided on the traction wheel 231. When the motor fails and cannot rotate, a wrench can be used to turn the traction wheel 231 through the reset hole so that the wire rope wound in the U-shaped receiving groove 2313 can be manually released to restore the brake pedal to its initial position to meet the driver's driving conditions.

[0053] Therefore, the vehicle brake system electronic control modification device in this embodiment is placed inside the housing 1 through the drive assembly 2, and one end of the traction assembly 3 is fixedly connected to the drive assembly 2, which is configured to be retractable and pullable. The brake pedal assembly 4 is fixedly connected to the other end of the traction assembly 3, and the brake pedal is forced to produce a stepping action through the retractable pulling of the traction assembly 3 to form a braking force. When the drive assembly is released, the brake pedal relies on its own reverse thrust to restore the initial position, so that the vehicle brake system can be electronically controlled to a certain extent, while retaining the manual driving mode.

[0054] The above one or more technical solutions in the embodiments of the present utility model have at least one or more of the following technical effects:

[0055] A vehicle brake system electronic control modification device provided in an embodiment of the utility model is used for braking a vehicle. The vehicle brake system electronic control modification device comprises: a housing, a drive assembly, a traction assembly, and a brake pedal assembly, wherein the interior of the housing has a first accommodating space, the drive assembly is arranged in the first accommodating space, the drive assembly comprises: a drive unit and an execution unit, the drive unit comprises a drive motor and a reducer, one end of the drive motor is connected to the reducer, the execution unit comprises a traction wheel and a limit cover, the traction wheel is connected to the output shaft of the reducer through a key transmission, the limit cover is arranged at one end of the traction wheel away from the reducer, the output shaft of the reducer is fixed to the traction wheel through the limit cover The traction assembly includes a plurality of traction ropes, one end of which is connected to the traction wheel; the brake pedal assembly is fixedly connected to the end of the traction assembly away from the driving assembly, and the brake pedal assembly includes: a first bracket, a first locking shaft, a second bracket and a second locking shaft, the first bracket is set at the first position of the mechanical pedal of the vehicle; the first locking shaft is fixedly connected to the first bracket; the second bracket is set at the second position of the mechanical pedal of the vehicle; the second locking shaft is rotatably connected to the second bracket, and the second locking shaft is fixedly connected to the end of the plurality of traction ropes away from the traction wheel. When the driving motor rotates, the driving execution unit rotates, and the traction rope is pulled and wound in the U-shaped receiving groove during the rotation process. As the traction rope is tightened, it pulls the second locking shaft to move downward, and at the same time pulls the original vehicle brake pedal downward, thereby braking the vehicle. When release is required, the drive motor reverses to release the traction rope, and the original vehicle brake pedal relies on its own internal reaction force to return to its original position, thus solving the problem that the existing technology cannot realize the electronic control of vehicle braking. If the original braking system is directly converted into an electronically controlled braking system as a whole, the cost is high, the installation is complicated, the destructiveness to the vehicle is large, and the subsequent maintenance is inconvenient. The technical problem has been achieved that the electronic control of the traditional vehicle braking system can be realized, the modification cost can be reduced, the flexibility of installation and maintenance can be improved, and the technical effect of coexisting both unmanned control and manned control can be satisfied.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0057] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention. Thus, if these modifications and variations of the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
