Technical Field

[0001] The present application relates to the field of automobile braking, and in particular to a vehicle braking mechanism. Background Art

[0002] AEB (Autonomous Emergency Braking) systems are widely used in automobiles to reduce the occurrence of traffic accidents. In AEB systems, a cable motor is usually used to assist braking. The cable motor controls the brake pedal of the car through a zipper to achieve the purpose of braking.

[0040] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0041] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0042] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0043] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0044] The specific implementation of the present application is described below in conjunction with the accompanying drawings.

[0045] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0046] In this article, "first", "second", etc. are only used to distinguish each other, and do not indicate the importance and order, or the premise of each other's existence.

[0047] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0048] For ease of understanding, refer to Figures 1 to 9 , the specific structure and working principle of the braking mechanism of the present application are explained in detail in combination with an embodiment.

[0049] This application relates to an AEB (Autonomous Emergency Braking) system, which can help vehicles actively brake in the event of a possible collision to avoid an accident or reduce the severity of a collision. It uses sensors and algorithms to detect whether there are obstacles or dangers ahead, and actively intervenes when the driver fails to react in time to enable the vehicle to perform braking operations.

[0050] Usually, a brake device is installed in the vehicle, which is generally composed of a pedal, a connecting rod connected to the pedal, and a fixing connecting the connecting rod and the vehicle. The connecting rod is configured to drive the pedal to move with the connecting end of the connecting rod and the fixing as the center of the circle, so as to put the vehicle into a braking state or release the braking state. The AEB system is an automatic emergency braking system installed on the brake device. When the vehicle needs to enter a braking state, the AEB system can simulate the user's braking to spontaneously drive the connecting rod and the pedal to the braking position.

[0051] In the design of existing AEB systems, a cable motor is usually set on the connecting rod, and a zipper fixing bracket of the cable motor zipper is fixed on the fixing part, and simulated braking is achieved by cooperating with the cable motor and the zipper fixing bracket. In order to ensure that the zipper fixing bracket can be stably fixed on the fixing part, a double-ear fixing method is usually used to fix the two, that is, both sides of the zipper fixing bracket are fixedly connected to both sides of the fixing part. However, the double-ear fixing method requires different types of zipper fixing brackets to be selected according to the width of the fixing part. Since the sizes of fixing parts of different car models are different, in order to better fix the zipper fixing bracket, different types of zipper fixing brackets need to be customized for different car models. This brings great inconvenience to the installation of the zipper fixing bracket. If an unsuitable zipper fixing bracket is used, the installation may be time-consuming or even impossible to complete.

[0052] Based on this, the present application provides a braking mechanism, which can simulate the user's braking when the vehicle needs to brake and spontaneously drive the connecting rod and the pedal to move to the braking position. Figure 1 , Figure 3The braking mechanism includes a braking module 1, a fixing module 2 and a driving device. The braking module 1 includes a fixing member 12, a connecting rod 13 and a pedal 14. The fixing member 12 is fixedly connected to the frame of the vehicle, and the connecting rod 13 has a first end 131 and a second end 132 opposite to each other, the first end 131 is connected to the fixing member 12, and the second end 132 is connected to the pedal 14. The fixing module 2 is fixed to one side of the fixing member 12. The driving device is arranged on the connecting rod 13, and the output end of the driving device is connected to the fixing module 2. The driving device is configured to apply a force to the connecting rod 13 and the pedal 14 so that the connecting rod 13 and the pedal 14 move with the first end 131 as the center of the circle, and when the vehicle needs to perform active braking, the driving device drives the connecting rod 13 and the pedal 14 to move toward the fixing module 2 until the connecting rod 13 and the pedal 14 move to the braking position to complete the braking, thereby realizing the vehicle performing a braking operation.

[0053] The fixing module 2 in the present application is fixed on the fixing member 12, and plays a role of connecting with the output end of the driving device, so that the driving device can drive the connecting rod 13 and the pedal 14 to move toward the fixing module 2 when outputting, which is the same as the zipper fixing bracket described above. Since the present application improves the fixing method of the zipper fixing bracket in the prior art, in which the two ears are fixed on both sides of the fixing member 12, to the fixing method in which the fixing module 2 is fixed on one side of the fixing member 12 by a single ear, on the basis of retaining the original function of the fixing member 12, the fixing module 2 does not need to consider the size of the fixing member 12, and can be installed in accordance with the fixing member 12 of any vehicle model, so that the fixing module 2 can be adapted to more different types of vehicles, and the assembly versatility of the fixing module 2 is improved. In addition, the fixing module 2 adopts a unilateral fixing method with the fixing member 12, and the installation position of the fixing module 2 can also be flexibly adjusted according to the actual installation environment, so as to reduce the interference of the fixing module 2 on the moving trajectory of the connecting rod 13.

[0054] In the brake mechanism provided by the present application, the fixing module 2 plays the role of the zipper fixing bracket in the prior art, and the fixing method between the fixing module 2 and the brake module 1 is a single-ear fixing method. Compared with the double-ear fixing method in the prior art, there is no need to consider the width of the fixing member 12, so there is no need to consider the impact of different car models on the fixing module 2, and there is no need to design the fixing module 2 separately for each car model, thus saving the design cost of the fixing module 2 and reducing the complexity of production. In addition, the brake mechanism is suitable for various car models and will not be incompatible with the car model, so it can also improve the assembly versatility.

[0055] In one embodiment of the present application, in order to ensure that the connecting rod 13 does not deviate in the direction in which the connecting rod 13 moves along the first end 131 of the connecting rod 13 as the center, reference Figure 1 , Figure 3The fixing member 12 is also provided with a rib 121 extending outward along the surface of the fixing member 12. The rib 121 cooperates with the guide of the connecting rod 13 to limit the deflection angle of the connecting rod 13 during the movement of the connecting rod 13. Two ribs 121 are provided, and are arranged on both sides of the fixing member 12. During the movement, the connecting rod 13 moves between the areas surrounded by the two ribs 121 to guide the movement direction of the connecting rod 13.

[0056] In one embodiment of the present application, the left and right sides of the fixing member 12 are further provided with assembly holes 122 for cooperating with the fixing module 2. In order to further improve the assembly versatility of the fixing module 2, the fixing module 2 in the present application has the performance of being assembled in both positive and negative ways, that is, the assembly holes 122 on either the left or right side can be selected to install the fixing module 2 according to the actual installation environment, so as to improve the assembly versatility of the braking device of the present application and enable it to adapt to more different installation environments.

[0057] In one application scenario of the present application, reference Figure 3 In the process of the brake mechanism receiving the brake command of the AEB system and executing the brake command, the driving device drives the connecting rod 13 to move in the direction of the fixed module 2. Since the driving device is fixedly connected to the connecting rod 13, the connecting rod 13 will move downward along the first end 131 of the connecting rod 13 as the center of the circle under the drive of the driving device until the connecting rod 13 moves to the preset position, that is, the braking position. In the process of the movement of the connecting rod 13, the pedal 14 fixedly connected to the connecting rod 13 will also move to the braking position together with the connecting rod 13. After the pedal 14 moves to the braking position, the vehicle is braked, that is, the vehicle performs the braking operation.

[0058] When the connecting rod 13 and the pedal 14 are in the braking position, the brake mechanism receives the brake release command of the AEB system and executes the brake release command. The driving device outputs in reverse to make the connecting rod 13 have a tendency to move away from the fixed module 2. Since the driving device is fixedly connected to the connecting rod 13, the connecting rod 13 will move upward along the first end 131 of the connecting rod 13 as the center of the circle under the drive of the driving device until the connecting rod 13 moves to the preset position, that is, to the brake release position. During the movement of the connecting rod 13, the pedal 14 fixedly connected to the connecting rod 13 will also move to the brake release position together with the connecting rod 13. After the pedal 14 moves to the brake release position, the vehicle releases the brake.

[0059] In one embodiment of the present application, the brake module 1 also includes a reset module, which is arranged between the fixing member 12 and the connecting rod 13. The reset module is configured to enable the connecting rod 13 to be located in an initial position, and when the connecting rod 13 is located at other positions, it can be reset to the initial position again under the action of the reset module.

[0060] In an application scenario of the present application, when the connecting rod 13 and the pedal 14 are in the braking position, after the brake mechanism receives the brake release command from the AEB system, it only needs to stop the operation of the driving device, and the connecting rod 13 can drive the connecting rod 13 and the pedal 14 to move upward to the initial position along the first end 131 of the connecting rod 13 under the action of the reset module, thereby completing the execution of the brake release command. Of course, it is also possible that the driving device outputs in the reverse direction to loosen the connection with the fixing module 2, and the connecting rod 13 always has a tendency to move away from the fixing module 2 under the cooperation of the reset module. As the driving device continues to move away, the connecting rod 13 gradually moves to the initial position to complete the execution of the brake release command, and the present application does not make too many restrictions here.

[0061] The reset module can be a compression spring, a torsion spring, a servo motor, a hydraulic assisted reset device, etc. Those skilled in the art can select and design it according to actual needs, and this application does not impose too many restrictions here.

[0062] In one embodiment of the present application, reference Figure 4 For the convenience of description, the top, bottom, left and right directions of the view are defined. It should be noted that the definition of the direction is only used to clearly illustrate the content of this application and does not impose any limitation on the protection scope of this application.

[0063] In order to further improve the installation versatility of the braking mechanism and enable the fixing module 2 to better cooperate with the driving device to achieve the purpose of braking, the fixing module 2 includes a first fixing module 21 and a second fixing module 22. The first end of the first fixing module 21 and the first end of the second fixing module 22 are connected, so that the first fixing module 21 and the second fixing module 22 are arranged at an angle.

[0064] Continue to refer Figure 4 In the viewing direction, the first end of the first fixing module 21 is the upper part of the first fixing module 21, the second end of the first fixing module 21 is the lower part of the first fixing module 21, the first end of the second fixing module 22 is the right part of the second fixing module 22, and the second end of the second fixing module 22 is the left part of the second fixing module 22.

[0065] The second end of the first fixing module 21 is fixed to one side of the fixing member 12, and the second end of the second fixing module 22 is connected to the output end of the driving device. The driving device is configured to apply a force to the connecting rod 13 and the pedal 14 to move toward the second fixing module 22, so that the connecting rod 13 and the pedal 14 move to the braking position.

[0066] Combined Figure 3By extending the length of the first fixing module 21, after the second end of the first fixing module 21 is unilaterally fixed to one side of the fixing member 12, space can be left for the installation position of the second fixing module 22, so that the fixing module 2 can effectively avoid the moving track of the rib 121 and the connecting rod 13 of the fixing member 12, which is conducive to further expanding the installation environment of the fixing module 2 of the present application and making it adaptable to more different types of vehicles.

[0067] In one embodiment of the present application, for ease of processing, the angle between the first fixing module 21 and the second fixing module 22 is 90°. Of course, the angle between the first fixing module 21 and the second fixing module 22 can also be any angle between 0° and 360°, and the present application does not impose too many restrictions on this.

[0068] In one embodiment of the present application, reference Figure 3 A first through hole 211 is provided at the end where the first fixing module 21 is fixed to the fixing member 12. The first fixing module 21 is fixed to one side of the fixing member 12 through the first through hole 211 to achieve fixed connection between the fixing module 2 and the fixing member 12.

[0069] In one embodiment of the present application, in order to further improve the installation stability of the fixing module 2 and reduce the impact of unilateral installation on the fixing module 2, an auxiliary fixing hole 222 is provided on one side of the second fixing module 22, and the auxiliary fixing hole 222 is configured to be fixedly installed together with the vehicle frame.

[0070] In a specific application scenario of this application, reference Figure 2 , Figure 3 The fixing member 12 is usually arranged on the frame of the vehicle. After the first fixing module 21 and the fixing member 12 are assembled together, the second fixing module 22 may appear to be fitted with the frame of the vehicle. In order to alleviate the instability of unilateral fixation between the fixing module 2 and the fixing member 12, the auxiliary fixing hole 222 on the second fixing module 22 is used to fix the fixing module 2 with the frame of the vehicle, so that the fixing module 2 and the frame of the vehicle are more stably connected together.

[0071] In one embodiment of the present application, reference Figure 4 In the viewing direction, the auxiliary fixing hole 222 is arranged on one side of the upper or lower part of the second fixing module 22, and can also be arranged on the top of the left part, and the present application does not make too many restrictions here.

[0072] In one embodiment of the present application, reference Figure 5 , Figure 6The fixing module 2 of the present application also includes a third fixing module 23, which is detachably connected to the second fixing module 22. The third fixing module 23 is configured to be connected to the output end of the driving device, and the driving device is configured to apply a force to the connecting rod 13 and the pedal 14 to move in the direction of the third fixing module 23, so that the connecting rod 13 and the pedal 14 move to the braking position.

[0073] In an application scenario of the present application, if the first fixing module 21 and the second fixing module 22 are directly installed on the fixing member 12, different vehicle types may have different design styles, resulting in the second fixing module 22 and the output end of the driving device not being on the same horizontal plane. In this way, the driving device may cause wear to the driving device due to the deviation of the output angle during output. Therefore, in order to make the output end of the driving device on the same horizontal plane as the connection end between it and the fixing module 2, the present application adds a third fixing module 23 that is detachably connected to the second fixing module 22 on the basis of the second fixing module 22, so that the output end of the driving device is arranged as horizontally coplanar as possible with the third fixing module 23. In this way, when the driving device drives the connecting rod 13 to drive the pedal 14 to move to the brake position, the third fixing module 23 can reduce the wear caused to the driving device, which is beneficial to extend the service life of the driving device.

[0074] In one embodiment of the present application, in order to reduce the loss of the driving device and shorten the output displacement of the driving device, it is necessary to set the output direction of the driving device as horizontal as possible with the position of the connection between the driving device and the fixing module 2. Figure 2 , the mounting portion 231 is horizontally coplanarly arranged with the second fixing module 22, the connecting portion 232 is vertically arranged with the second fixing module 22, and the connecting portion 232 is horizontally arranged with the output end of the driving device;

[0075] The connecting portion 232 is provided with a sliding pin 24 and a locking device 25 , the output end of the driving device is installed between the sliding pin 24 and the locking device 25 , and the locking device 25 locks the output end of the driving device in the installation position.

[0076] In one application scenario of the present application, reference Figure 3, the driving device is arranged on the connecting rod 13, and the output end of the driving device is arranged in the direction where the fixing member 12 is located. After the mounting portion 231 of the third fixing module 23 is assembled with the second fixing module 22, the first through hole 211 of the first fixing module 21 is assembled with the assembly hole 122 on the fixing member 12, thereby completing the assembly between the fixing module 2 and the fixing member 12. After the assembly of the fixing module 2 and the fixing member 12 is completed, the relative position between the third fixing module 23 and the second fixing module 22 can be adjusted according to the position of the output end of the driving device, so that the connecting portion 232 of the third fixing module 23 is arranged horizontally with the output end of the driving device. Such an arrangement can expand the installation scenario of the fixing module 2 while minimizing the loss of the driving device, which is beneficial to prolonging the service life of the driving device.

[0077] In one embodiment of the present application, reference Figure 2 The second fixing module 22 is provided with at least one mounting hole 221, and the third fixing module 23 is provided with a through slot 2311 adapted to the mounting hole 221, and the third fixing module 23 is installed with the second fixing module 22 through the through slot 2311 and the mounting hole 221. After the relative position between the third fixing module 23 and the second fixing module 22 is adjusted, the third fixing module 23 is fixedly connected with the second fixing module 22 by matching the through slot 2311 and the mounting hole 221 with bolts.

[0078] In one embodiment of the present application, reference Figure 5 , Figure 7 For the purpose of adjusting the relative position between the output end of the driving device and the third fixing module 23, the third fixing module 23 includes a mounting portion 231 and a connecting portion 232, wherein the mounting portion 231 is provided with a through groove 2311 adapted to the mounting hole 221; the connecting portion 232 is configured to be connected to the output end of the driving device, and the driving device is configured to apply a force to the connecting rod 13 and the pedal 14 to move in the direction of the connecting portion 232 so that the connecting rod 13 and the pedal 14 move to the braking position.

[0079] The connection part 232 can make the third fixing module 23 better cooperate with the output end of the driving device. The connection part 232 is arranged toward the output end of the driving device so that the driving device can drive the connecting rod 13 and the pedal 14 to move with the maximum displacement with the least possible output, which is beneficial to improving the working efficiency of the driving device.

[0080] In one embodiment of the present application, reference Figure 6 , Figure 8, at least three mounting holes 221 are provided on the second fixing module 22, and the at least three mounting holes 221 are configured to be spaced apart along the axial direction of the second fixing module 22, and the mounting portion 231 is configured to be selectively mounted in cooperation with the mounting holes 221 to adjust the relative position between the third fixing module 23 and the second fixing module 22.
