Description
TECHNICAL FIELD
[0001] The application relates to a connecting device in a vehicle braking system, in particular to a connecting mechanism of an auxiliary brake. BACKGROUND
[0002] With the rapid development of intelligent driving technology, more and more cars are equipped with various advanced driving assistance systems (ADAS). Among them, the auxiliary brake system as one of the important subsystems can quickly respond in emergency situations to avoid or mitigate the occurrence of collision accidents. The widespread application of such systems not only improves driving safety, but also provides a solid foundation for the development of autonomous driving technology.
[0003] In the prior art, when testing the auxiliary brake of the driving assistance system, the integration of the ranging radar and the auxiliary brake system is used. The existing auxiliary brake system is usually equipped with a high-precision ranging radar, which can measure the distance of the obstacle in front of the vehicle in real time and transmit the data to the central processor. Once a potential danger is detected, the central processor will quickly issue an instruction to start the auxiliary brake system. As for the brake mode, in the auxiliary brake system installed, the brake is usually realized by pulling the brake pedal through the motor. Specifically, two iron sheets are installed on the support arm of the brake pedal and fixed by bolts, and one end of the steel wire rope is fixed on the motor and the other end is connected to the two iron sheets. Although this method is simple and easy to implement, it may loosen after a long time of use, the iron sheet clamping is not firm, and the phenomenon of slipping may occur, which may cause the brake to be not timely and affect the deceleration effect of the auxiliary brake. In addition, the steel wire rope is easily worn out or even broken due to long-term tension and friction, increasing the maintenance cost and the replacement frequency, which will increase the workload of the test personnel.
[0004] Therefore, how to design a connecting mechanism of an auxiliary brake with simple structure and high reliability is a technical problem to be solved at present. CONTENT OF THE INVENTION
[0005] The purpose of the present application is to overcome the above technical problems, and provide a connecting mechanism of an auxiliary brake, which specifically adopts the following scheme:

[0007] By adopting the above technical scheme, the connecting mechanism of the auxiliary brake can effectively bind the steel wire rope and reliably transmit force. Specifically, the design of the fastener enables the connecting mechanism to be firmly installed on the support arm of the brake pedal, ensuring the stability and safety of the entire structure. The combination of the base, the fixing member and the guide wheel in the sliding assembly ensures that the steel wire rope can be effectively bound at a fixed position.
[0008] Optionally, the middle part of the guide wheel is provided with a V-shaped groove for binding the steel wire rope in the V-shaped groove.

At the same time, the two ends of the end surface are designed as flat surfaces, which can better abut against and fit the square support arm of the brake pedal to prevent slipping, further enhancing the applicability and reliability of the connecting mechanism. This structural design not only improves the overall stability and safety of the connecting mechanism, but also increases the compatibility with different shaped support arms.
[0012] Optionally, one end of the fixing member is provided with a thread, and the fixing member is screwed and fixed on the base through the thread, and a threaded groove is arranged on the base correspondingly.
[0013] By adopting the above technical scheme, the design of the thread at one end of the fixing member and the screwing and fixing of the fixing member on the base through the thread make the connection between the fixing member and the base more stable and reliable. At the same time, the threaded groove arranged on the base can ensure the accuracy and stability of the installation of the fixing member, thereby effectively avoiding safety hazards caused by looseness. This structure not only improves the mechanical strength of the entire connecting mechanism, but also facilitates maintenance and replacement of parts.
[0014] Optionally, a friction groove is arranged on the surface of the end of the fixing member away from the thread.
[0015] By adopting the technical scheme, the friction groove is arranged on the surface of the end of the fixing member away from the screw thread, so that the operator can conveniently disassemble and assemble the fixing member from the base.
[0016] Optionally, the fixing member is provided with a space for axial movement of the guide wheel, and the guide wheel is arranged radially rotatable on the fixing member.
[0017] By adopting the technical scheme, the space for axial movement of the guide wheel is arranged on the fixing member, so that the steel wire rope can be appropriately adjusted in the axial direction when under stress, thereby reducing the abrasion and rupture risk caused by the change in the tension of the steel wire rope. Meanwhile, the guide wheel is arranged radially rotatable on the fixing member, which can ensure that the steel wire rope is always in the best contact state during movement, improve the transmission efficiency, reduce the friction loss, and prolong the service life.
[0018] Optionally, the fastener is provided with a locking member for locking the two ends of the fastener after adjusting the length of the fastener.
[0019] By adopting the technical scheme, the space for axial movement of the guide wheel is arranged on the fixing member, so that the steel wire rope can be appropriately adjusted in the axial direction when under stress, thereby reducing the abrasion and rupture risk caused by the change in the tension of the steel wire rope. Meanwhile, the guide wheel is arranged radially rotatable on the fixing member, which can ensure that the steel wire rope is always in the best contact state during movement, improve the transmission efficiency, reduce the friction loss, and prolong the service life.
[0020] Optionally, the fastener is provided with a plurality of limiting holes for adapting to the locking member.
[0021] By adopting the technical scheme, the plurality of limiting holes arranged on the fastener can adapt to the locking member, so that the position of the fastener can be more accurately locked after adjusting the length of the fastener, thereby ensuring the stability and reliability of the connecting mechanism on brake pedals of different sizes. Meanwhile, this design also improves the convenience of installation and adjustment, so that the user can quickly complete the assembly according to actual needs.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. By adopting the design of the fastener and the sliding assembly, the steel wire rope can be more stably bound to the support arm of the brake pedal, effectively preventing the loosening and slipping phenomenon that may occur after long-term use, and improving the reliability and stability of the auxiliary brake system.

Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified.
[0032] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0033] Referring to Figure 1 , the connecting mechanism of an auxiliary brake disclosed in the embodiments of the present application includes a fastener 10 and a sliding assembly 20, the fastener 10 is used to bind on the support arm of the brake pedal, the sliding assembly 20 includes a base 21, a fixing piece 22 and a guide wheel 23, the base 21 is fixed on the fastener 10, the fixing piece 22 is sleeved on the guide wheel 23 and fixed on the base 21, and the guide wheel 23 is provided on the fixing piece 22 for binding a steel wire rope.
[0034] The fastener 10 is a metal ring with multiple limiting holes 12, and a locking piece 11 is arranged on the fastener 10, the locking piece 11 is provided with a screw piece, the multiple limiting holes 12 are matched with the locking piece 11, the rotation of the screw piece drives the internal limiting sheath (not shown in the figure) to be embedded in different limiting holes 12, and meanwhile, one end of the fastener 10 is moved to lock the support arm of the brake pedal, so as to ensure the stability and reliability of the connecting mechanism on the support arm of different sizes.
[0035] The base 21 is fixed on the fastener 10, and the fixing can be achieved by welding, bonding or screw and the like, which is not limited herein. The end face of the base 21 away from the guide wheel 23 (that is, the end face abutting against the support arm) is designed as a circular arc V-shaped groove in the middle part and flat on both sides, so as to better fit the circular or square brake pedal support arm. Specifically, the middle part is designed as a circular arc V-shaped groove, which can effectively adapt to and fit the cylindrical support arm of the brake pedal, and the both sides of the base 21 are designed as flat surfaces, which can better abut and fit the square support arm of the brake pedal. In this way, the structure design of the end face of the base 21 away from the guide wheel 23 can enhance the applicability and reliability of the connecting mechanism.
[0036] Referring to Figure 2 , one end of the fixing piece 22 is provided with a thread 221, which can be fixed in the threaded groove 211 on the base 21 by screwing. The other end surface of the fixing piece 22 is provided with multiple friction grooves 222, which form a structure as shown in Figure 2 , in the disassembly process, the hand contacts the friction grooves 222 for rotation, which can increase the screwing friction force to achieve the labor-saving effect.
[0037] In the fixing piece 22, there is enough space for the guide wheel 23 to move axially on the fixing piece 22, and the guide wheel 23 is radially rotatable on the fixing piece 22. The advantage of this design is that the guide wheel 23 can freely roll during the pulling of the steel wire rope, which reduces the friction resistance of the steel wire rope and prolongs the service life of the steel wire rope.
[0038] Referring to Figure 2 , the middle part of the guide wheel 23 is designed as a V-shaped groove shape, which is convenient for the steel wire rope to be bound thereon.

[0039] The implementation principle of the embodiment is that the whole connecting mechanism is firmly fixed on the support arm of the brake pedal through the fastener 10, so as to ensure the stability of the connecting mechanism. The design of the base 21 and the fixing part 22 in the sliding assembly 20 enables the guide wheel 23 to freely move and rotate within a certain range, reduces the friction loss of the steel wire rope, and improves the reliability of the system.

The one end surface of the base 21 is provided with a circular arc V-shaped groove and a flat surface, which can adapt to brake pedal support arms of different shapes, ensure good contact and stability of the connecting mechanism and the support arm, and enhance the application range and reliability of the overall structure. The fixing part 22 is provided with a space for axial movement of the guide wheel 23, so that the steel wire rope can be appropriately adjusted in position in the axial direction when subjected to force, thereby reducing the wear and tear and rupture risk caused by changes in the tension of the steel wire rope. At the same time, the guide wheel 23 is radially rotatably arranged on the fixing part 22, which can ensure that the steel wire rope is always in the best contact state during movement, improve the transmission efficiency, reduce the friction loss, and prolong the service life. Compared with the traditional iron sheet fixing method, the connecting mechanism has higher reliability and longer service life, effectively solving the problems existing in the prior art.
