Description

Technical Field

[0001] This utility model relates to the field of brake testing technology, and in particular to a brake testing mechanism. Background Technology

[0002] In the field of motor vehicle driving skills training and testing, instructors and examiners need to accurately supervise and evaluate the driving operations of trainees. Braking is the core of vehicle control, directly affecting the safety of driving skills training, the fairness of testing, and the correctness of driving habits. A trainee's ability to correctly use the brakes in complex road conditions is a key indicator of their driving proficiency and safety awareness.

[0003] Currently, most driving school training vehicles and test vehicles are converted from traditional gasoline-powered cars. These vehicles are originally designed to meet the driving needs of ordinary users, and their vehicle status monitoring systems (such as instrument clusters and CAN bus data) mainly serve the vehicle's own status diagnosis and display, without being optimized for the special application scenarios of "teaching supervision" and "examination evaluation".

[0004] The following are prominent problems and deficiencies in the teaching and testing practice of existing fuel-powered vehicles: The assessment process is highly subjective and lacks objective arbitration criteria: When determining whether necessary deceleration or pre-braking actions were taken at specific points such as intersections and pedestrian crossings, examiners often rely on their personal experience and subjective perception of vehicle dynamics. This approach lacks objective and standardized judgment, easily leading to disputes. When trainees object to the assessment results, the testing system cannot provide crucial operational data such as "whether any braking action was taken" as arbitration evidence, affecting the fairness and authority of the examination.

[0005] The lack of operational data analysis hinders precise teaching: Existing training vehicles cannot record students' braking operation data during training (such as the number of times, timing, and duration of braking). During post-training debriefings, instructors can only provide general evaluations of students' braking performance based on memory, unable to conduct quantitative analysis or provide targeted guidance. This hinders the identification of deeper problems in students' operating patterns (such as braking too late when following another vehicle, or insufficient deceleration before cornering), limiting the improvement of teaching effectiveness.

[0006] Therefore, due to the limitations of their original architecture, existing training and testing vehicles based on traditional fuel vehicles are in a state of "internal state opacity" regarding the braking operation of students in training and testing scenarios. This state affects teaching efficiency and testing fairness.

[0007] Based on this, the present invention designs a brake detection mechanism to solve the above problems. Utility Model Content

Detailed Implementation

[0017] Please see Figures 1 to 3 As shown, this utility model provides a brake detection mechanism. To better understand the above technical solution, the following will describe the above technical solution in detail with reference to the accompanying drawings and specific embodiments.

[0018] In a specific embodiment of the technical solution of this utility model: 1. Bracket; 2. Connecting rod; 3. Slider; 4. Limiting screw; 5. Spring; 6. Connecting plate; 7. Limiting plate; 8. Connecting shaft; 9. L-shaped connecting rod; 10. Pressure sensor; and 11. Controller. The bracket 1 is rectangular. The upper part of the bracket has a connecting hole 11 in the horizontal direction, the middle part of the bracket has a groove 12, and the lower part of the bracket has a groove 13. The bracket 1 is rotatably connected between the brake pedal 14 and the L-shaped connecting rod 9. The bracket 1 is rotatably connected to the brake pedal 14 of a conventional fuel vehicle through the connecting hole 11.

[0019] The connecting rod 2 is a straight rod, and it is fixedly connected to the upper part of the groove 12. The upper part of the slider 3 is provided with a cavity 31, which penetrates the upper surface of the slider 3. The connecting rod 2 is inserted into the cavity. The connecting rod 2 and the cavity 31 cooperate with each other to restrict the movement trajectory of the slider 3. That is, the slider 3 can only slide up and down, and it can only slide upward until the bottom of the cavity 31 contacts the bottom of the connecting rod 2.

[0020] The limiting screw 4 is connected to the lower part of the groove 12. The spring 5 is located inside the groove 12 and is sleeved on the limiting screw 4. The slider 3 is elastically connected to the spring 5. The limiting screw 4 can adjust the downward sliding distance of the slider 3 so that when the slider 3 slides down to the lowest point, it just touches the pressure sensor 10, preventing the trigger 81 from hitting the pressure sensor 10 and causing damage to the pressure sensor. The limiting screw 4 plays the role of adjusting the cooperation between the pressure sensor 10 and the trigger 81. The spring 5 always applies an upward force to the slider 3, so that when no one steps on the brake pedal, the bottom of the cavity 31 contacts the bottom of the connecting rod 2.

[0021] The connecting plate 6 is located inside the groove 12, and the bottom of the connecting plate 6 is fixedly connected to the bottom of the groove 12. The connecting plate 6 is located on the left side of the slider 3. The connecting plate 6 can restrict the slider 3 from moving to the left and prevent the slider 3 from being hit from the left side.

[0022] The limiting plate 7 is located in the groove 12, and there are two limiting plates 7, which are respectively located on the front and rear sides of the slider 3. The limiting plate 7 is fixedly connected to the connecting plate 6. The limiting plate 7 can restrict the forward and backward movement of the slider 3 and prevent the slider 3 from sliding out of the groove 12.

[0023] The lower part of the connecting plate 6 is provided with a cavity 61, and the connecting shaft 8 is movably installed in the cavity 61. The connecting shaft 8 passes through the cavity 61 and is fixedly connected to the slider 3. The connecting shaft 8 can move up and down in the cavity, thereby driving the slider 3 to slide up and down.

[0024] The connecting shaft 8 is rotatably connected to the L-shaped connecting rod 9; that is, the bracket 1 is rotatably connected between the brake pedal 14 and the L-shaped connecting rod 9.

[0025] The pressure sensor 10 is located below the connecting shaft 8, and the pressure sensor 10 does not contact the connecting shaft 8. The pressure sensor 10 is located in the groove 13. A trigger 81 is fixedly connected below the connecting shaft 8. The trigger 81 is located in the groove 13 and directly above the pressure sensor 10. The trigger 81 can trigger the pressure sensor 10.

[0026] The pressure sensor 10 is electrically connected to the controller. The pressure sensor 10 transmits pressure signals to the controller, recording whether the trainee has pressed the brake pedal 14, thus improving the safety, efficiency, and fairness of driving skills training and testing. Preferably, the system also includes a display, which is electrically connected to the pressure sensor 10. Driving instructors can use the display to determine in real-time and intuitively whether the student has applied the brakes, further ensuring teaching safety.

[0027] Preferably, the system further includes a baffle 82, which is fixedly sleeved on the connecting shaft 8 and contacts the connecting plate 6. The baffle 82 blocks the L-shaped connecting rod 9 from the connecting plate 6. The baffle 82 separates the L-shaped connecting rod 9 and the connecting plate 6, preventing them from rubbing against each other and causing wear. The baffle 82 also restricts the position of the connecting shaft 8, preventing it from extending further into the groove 12 and damaging the slider 3 or the connecting rod 2.

[0028] Preferably, the L-shaped connecting rod 9 is fixedly connected to the vehicle body, and the L-shaped connecting rod 9 is located above the accelerator pedal. When the student presses the brake pedal 14, the bracket 1 is rotatably connected between the brake pedal 14 and the L-shaped connecting rod 9, which can prevent the bracket from extending downwards continuously, thus preventing the brake pedal 14 from being fully depressed, or damaging the present invention.

[0029] In its normal state, the bracket 1 is rotatably connected between the brake pedal 14 and the L-shaped connecting rod 9. The spring 5 continuously applies an upward force to the slider 3, causing the bottom of the cavity 31 to contact the bottom of the connecting rod 2. At this time, the trigger 81 and the pressure sensor 10 are not in contact. When the student presses the brake pedal 14, the connecting shaft 8 drives the trigger 81 and the slider 3 to move downward. When the slider 3 touches the limit screw 4, the trigger 81 just touches the pressure sensor 10. The pressure sensor 10 then transmits the pressure signal to the controller and the display. When the student releases the brake pedal 14, the spring 5 pushes the slider 3 to the position where the bottom of the cavity 31 is at the bottom of the connecting rod 2, and the trigger 81 moves away from the pressure sensor 10.

[0030] It should be noted that the terms “horizontal,” “front,” “back,” “left,” “inner,” “up,” “down,” and similar expressions used in this article are for illustrative purposes only.

[0031] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
