[0046] Example 1

[0047] Reference Figure 1 , Figure 2 , which is the first embodiment of the present invention, and provides an auxiliary brake system for large vehicles. The auxiliary brake system 100 includes a main controller 101, a detection radar 102, a vehicle speed sensor 103, an alarm 104 and a controller 105. The detection radar 102, the vehicle speed sensor 103, the alarm 104 and the controller 105 are respectively connected to the main controller 101;

[0048] Since the blind spots of large vehicles are mainly concentrated on the right side of the vehicle, the detection radar 102 of the present invention includes a first radar 102a and a second radar 102b. The first radar 102a is installed on the right side of the front bumper of the vehicle 200 through the installation component 300, and the second radar 102b is installed on the right front wheel of the vehicle 200 through the installation component 300.

[0049] Among them, the detection radar 102 is used to receive configuration data and detect objects within a predetermined distance in the blind spot of the vehicle 200 according to a predetermined angle; the vehicle speed sensor 103 is used to obtain the driving speed of the vehicle 200; the alarm 104 is used to issue an alarm message; the controller 105 is connected to the brake pedal and is used to control the movement of the brake pedal. The controller 105 can adopt existing technical means, such as the actuator disclosed in the patent (publication number CN209492449U, publication date 2019.10.15). The actuator is connected to the brake pedal through a pull rope, and the brake pedal is pulled down by the pull rope, replacing the driver's stepping on the brake pedal to achieve the purpose of braking.

[0050] It should be noted that the main controller 101 adopts MCU, model STM32F103, which is mainly used for data collection and analysis, and outputs the judgment results; the detection radar 102 adopts ultrasonic radar, model TD6900, which is used to monitor whether there are objects entering the blind spot and the speed of the object's movement, and the object includes motorcycles, bicycles, pedestrians, etc.; the vehicle speed sensor 103 includes a CAN communication module and a three-axis sensor. The CAN communication module is connected to the CAN bus of the vehicle 200, and uses CAN and IO communication to collect the vehicle 200's own data, such as the driving speed, the signal of the vehicle 200 turn signal, the brake signal, the gear signal, etc.; the three-axis sensor, model HAAM-313B, is used to calculate the posture of the vehicle 200, such as speed, driving amplitude, etc.; the speed of the vehicle 200 is obtained through CAN communication and three-axis sensor calculation, and the speed acquisition result is more accurate; the alarm 104 adopts a buzzer, which is used to sound an alarm, and the buzzer is used to prompt when danger is detected or the system is abnormal.

[0051] The present invention collects information about the vehicle 200 itself, such as the driving speed, through the vehicle speed sensor 103; scans, detects and analyzes obstacles in the blind spot of the vehicle 200 through the detection radar 102; monitors motorcycles, bicycles and pedestrians in the blind spot of the vehicle 200 based on real-time data during the driving process of the vehicle 200. Once there is danger in this area, the alarm 104 sounds an alarm to remind the driver of the blind spot danger so that the driver can make better judgments and reasonable operations, thereby reducing the risk of accidents or injuries; braking measures are taken when and only when the reminder is invalid and the accident is unavoidable, and braking is achieved by controlling the movement of the brake pedal through the controller 105 to reduce accident damage.

[0052] Example 2

[0053] Reference Figures 3 to 5 , this embodiment is different from the first embodiment in that: the detection radar 102 used in this embodiment is a columnar ultrasonic radar. Since the diameters of the detection radars 102 produced by different manufacturers may be different, the installation of the detection radar 102 requires a dedicated mounting seat. Detection radars 102 of different sizes require mounting seats of different sizes to correspond thereto, resulting in inconvenience in installation; therefore, the installation assembly 300 of this embodiment includes a locking member 301 and an operating member 302, and the locking member 301 and the operating member 302 are both sleeved on the outside of the detection radar 102, wherein the locking member 301 is provided with an installation cavity N4, for the cylindrical section of the detection radar 102 to be inserted; wherein, the locking member 301 is provided with a plurality of elastic arms 301a located on the outside of the detection radar 102, and the operating member 302 is sleeved on the outside of the elastic arms 301a and can squeeze the elastic arms 301a inwardly, and the inner diameter of the installation cavity N4 is reduced by squeezing the elastic arms 301a, so as to achieve the purpose of fastening the detection radar 102 in the installation cavity N4, and the initial inner diameter of the installation cavity N4 is larger than the outer diameter of the commercially available detection radar 102. This embodiment can adapt to the installation of detection radars 102 of different sizes within a certain range, thereby improving the scope of application;

[0054] It should be noted that the operating member 302 and the locking member 301 are fixed to each other through the limiting component 303. After the operating member 302 is fastened to the detection radar 102 through the elastic arm 301a, it is fixed to the locking member 301 through the limiting component 303, so that the detection radar 102 can be kept in a fixed state, and finally the whole can be installed on the vehicle 200.

[0055] Example 3

[0056] Reference Figures 5 to 8, this embodiment is different from the above embodiment in that: the locking member 301 includes a first cylinder 301b and a second cylinder 301c fixed to each other, the first cylinder 301b and the second cylinder 301c of this embodiment are both hollow cylinders, the second cylinder 301c is located inside the first cylinder 301b, the elastic arm 301a is fixedly connected to the second cylinder 301c, and the inner cavity of the second cylinder 301c forms a mounting cavity N4;

[0057] It should be noted that the operating member 302 is provided with an inner cavity N3 capable of accommodating the elastic arm 301a, one end of the inner cavity N3 is open, and the other end of the inner cavity N3 is provided with a through hole with a diameter smaller than the opening, and an inclined extrusion surface S1 is provided in the inner cavity N3, and the extrusion surface S1 is inclined in the direction from the opening to the through hole; wherein the elastic arm 301a is inclinedly arranged in coordination with the extrusion surface S1, the fixed end of the elastic arm 301a is fixed on the second cylinder 301c, and the movable end of the elastic arm 301a is inclined toward the installation cavity N4;

[0058] The operating member 302 is generally in the shape of a hollow column, and a receiving cavity N1 capable of receiving the operating member 302 is reserved between the first cylinder 301b and the second cylinder 301c. During installation, the detection radar 102 is inserted into the installation cavity N4 of the second cylinder 301c, and then the operating member 302 is inserted into the receiving cavity N1. The operating member 302 is moved, and the extrusion surface S1 of the inner cavity N3 of the operating member 302 contacts the outer surface of the elastic arm 301a. Through the matching of the inclined surfaces, the operating member 302 is continuously moved until the elastic arm 301a is squeezed inward and the detection radar 102 is fastened to achieve fixation.

[0059] It should be noted that the operating member 302 is connected to the first cylinder 301b through the limiting component 303. After the operating member 302 moves, it is fixed by the limiting component 303, so that the fixed state of the detection radar 102 can be maintained.

[0060] Specifically, the limiting assembly 303 includes a block 303a located on the operating member 302 and a limiting groove 303b located in the first cylinder 301b. The block 303a and the limiting groove 303b are embedded and connected. The block 303a on the operating member 302 is embedded in the limiting groove 303b of the first cylinder 301b to achieve the fixation of the two.

[0061] Among them, a stopper 301d is also provided in the accommodating cavity N1. When the operating member 302 contacts the stopper 301d, the block 303a is embedded in the limiting groove 303b. The stopper 301d is used to determine the moving position of the operating member 302. When the operating member 302 is moved and the elastic arm 301a is squeezed inward, until the operating member 302 contacts the stopper 301d, the block 303a is embedded in the limiting groove 303b to be fixed.

[0062] Example 4

[0063] Reference Figures 5 to 10 , this embodiment is different from the above embodiments in that: a plurality of limiting grooves 303b arranged along the axial direction are provided in the first cylinder 301b. In Embodiment 3, the operating member 302 can only be fixed to the first cylinder 301b at a specific position. Since the diameters of the detection radars 102 produced by different manufacturers may be different, although the specific position can ensure the fixation of the detection radars 102 within a certain size range, the scope of application is still limited. In this embodiment, a plurality of limiting grooves 303b are provided in the first cylinder 301b, which can limit the different axial positions of the operating member 302 in the accommodating cavity N1, that is, the amplitude of the inward squeezing of the elastic arm 301a can be limited. The deeper the position of the operating member 302 in the accommodating cavity N1, the greater the amplitude of the inward squeezing of the elastic arm 301a, and the smaller the diameter of the detection radar 102 can be fixed;

[0064] It should be noted that a spring 301f is also provided in the accommodating chamber N1, which is sleeved on the outside of the second cylinder 301c. The spring 301f is connected between the stopper 301d and the end cover 301b-1 of the first cylinder 301b, and the second cylinder 301c and the end cover 301b-1 are fixed to each other; the operating member 302 is inserted into the accommodating chamber N1, and the operating member 302 first contacts the stopper 301d, and then continues to move the operating member 302 to push the stopper 301d to compress the spring 301f to move. At the same time, the operating member 302 squeezes the elastic arm 301a inward until the block 303a on the operating member 302 is limited to a certain limiting groove 303b in the first cylinder 301b, and the block 303a is embedded in the limiting groove 303b to achieve fixation.

[0065] It should be noted that the stopper 301d is annular and sleeved on the outside of the second cylinder 301c. In order to ensure that the stopper 301d can move in a straight line, sliders 301d-1 are evenly distributed on the annular inner wall of the stopper 301d, and sliding grooves 301c-1 corresponding to the sliders 301d-1 are distributed on the outer wall of the second cylinder 301c. The guided movement of the slider 301d-1 in the sliding groove 301c-1 can ensure the linear movement of the stopper 301d and prevent the stopper 301d from rotating circumferentially.

[0066] Example 5

[0067] Reference Figures 5 to 10, this embodiment is different from the above embodiment in that: the first cylinder 301b is provided with axially arranged oblique teeth 301e, and a limiting groove 303b is formed between two adjacent oblique teeth 301e, wherein the clamping block 303a is wedge-shaped and matched with the oblique teeth 301e, and the wedge-shaped inclined surface of the clamping block 303a faces the stopper 301d, and the inclined surface of the oblique teeth 301e faces the clamping block 303a, that is, the clamping block 303a can move into the accommodating chamber N1 under the action of the oblique teeth 301e, but when the clamping block 303a extends into the limiting groove 303b, the clamping block 303a cannot move outward; that is, the operating member 302 can only move unidirectionally into the accommodating chamber N1;

[0068] It should be noted that, due to the effect of the beveled teeth 301e, when the wedge-shaped inclined surface of the block 303a contacts the inclined surface of the beveled teeth 301e, the operating member 302 continues to move, and only by squeezing the stopper 301d can the block 303a be moved from one limiting groove 303b to another limiting groove 303b; therefore, a radially extending sliding cavity N2 is provided on the operating member 302, and the block 303a is slidably connected to the sliding cavity N2, and the depth of the sliding cavity N2 can meet the requirement that the block 303a is completely hidden in the sliding cavity N2, and the block 303a is connected to the bottom of the sliding cavity N2. There is an elastic member 303a-1, which can be a spring or a spring. After the wedge-shaped inclined surface of the block 303a contacts the inclined surface of the bevel tooth 301e, the operating member 302 continues to move to squeeze the stop member 301d into the sliding cavity N2. When it moves into the limiting groove 303b, the block 303a is reset under the action of the elastic member 303a-1, so that the block 303a is embedded in the limiting groove 303b, and the operating member 302 can continue to be moved into the accommodating cavity N1, so that the block 303a moves from one limiting groove 303b to another limiting groove 303b.

[0069] In order to achieve the fixing stability of the operating member 302, the blocks 303a are evenly distributed along the circumference of the operating member 302, and the oblique teeth 301e are evenly distributed corresponding to the blocks 303a. The axial stable fixation of the operating member 302 is achieved by multiple circumferential blocks 303a.

[0070] In order to prevent the operating member 302 from rotating circumferentially in the accommodating chamber N1, a guide groove 301b-1 is further provided on the first cylinder 301b, and a guide block 302a matching the guide groove 301b-1 is provided on the operating member 302. When the operating member 302 moves axially into the accommodating chamber N1, it is guided and moved in the guide groove 301b-1 by the guide block 302a. At the same time, since the guide block 302a is embedded in the guide groove 301b-1, the operating member 302 can be prevented from rotating circumferentially in the accommodating chamber N1.

[0071] Working principle of the present invention:

[0072] During installation, the detection radar 102 is inserted into the installation cavity N4 of the second cylinder 301c, and then the operating member 302 is inserted into the accommodating cavity N1, and the operating member 302 is moved, and the operating member 302 first contacts the stopper 301d, and the operating member 302 is continued to move to push the stopper 301d to compress the spring 301f, and the extrusion surface S1 of the inner cavity N3 of the operating member 302 contacts the outer surface of the elastic arm 301a, and through the inclined surface cooperation, the elastic arm 301a is pressed inward and the detection radar 102 is tightened, so that the detection radar 102 is fixed;

[0073] During the movement of the operating member 302, after the wedge-shaped inclined surface of the block 303a contacts the inclined surface of the bevel tooth 301e, the operating member 302 continues to move, and the stopper 301d is squeezed into the sliding cavity N2. When it moves into the limiting groove 303b, the block 303a is reset under the action of the elastic member 303a-1, so that the block 303a is embedded in the limiting groove 303b. The operating member 302 can continue to be moved into the accommodating cavity N1, so that the block 303a moves from one limiting groove 303b to another limiting groove 303b. When fastening the detection radar 102, the block 303a is embedded in the limiting groove 303b, so that the detection radar 102 can be kept in a fixed state, and finally the whole can be installed on the vehicle 200.

[0074] The present invention collects information about the vehicle 200 itself, such as the driving speed, through the vehicle speed sensor 103; scans, detects and analyzes obstacles in the blind spot of the vehicle 200 through the detection radar 102; monitors motorcycles, bicycles and pedestrians in the blind spot of the vehicle 200 based on real-time data during the driving process of the vehicle 200. Once there is danger in this area, the alarm 104 sounds an alarm to remind the driver of the blind spot danger so that the driver can make better judgments and reasonable operations, thereby reducing the risk of accidents or injuries; braking measures are taken when and only when the reminder is invalid and the accident is unavoidable, and braking is achieved by controlling the movement of the brake pedal through the controller 105 to reduce accident damage.
