Description

Technical Field

[0001] This utility model relates to the field of automotive brake pedal technology, and in particular to a pedal height measuring structure for detecting automotive foot pedal braking. Background Technology

[0002] The brake pedal is a component in a car's braking system used to control braking. It is usually located in front of the driver's seat. The driver depresses the brake pedal to slow down or stop the vehicle. The depth to which the brake pedal is pressed is closely related to the braking force output. By detecting the depth of the pedal, the working status of the braking system can be intuitively understood.

[0003] The brake pedal parameters were originally set manually by rotating the angle. However, the angle rotation was not always accurate, and there were batch differences in the angle settings, which greatly affected the use of the brake pedal and also resulted in a huge amount of manual work.

[0004] The existing patent (publication number: CN207095849U) discloses a brake pedal testing fixture. This utility model brake pedal testing fixture greatly facilitates the debugging process, reduces the workload of manual labor, and improves the accuracy of debugging.

[0005] To address the aforementioned issues, existing patents offer solutions. However, some existing methods for measuring the movement data of a car's brake pedal, especially in ordinary auto repair shops, involve manual measurement using a ruler while bending over. Manual measurement with a ruler is inefficient and easily affected by factors such as the operator's technique and reading errors, resulting in low measurement accuracy. Furthermore, manual measurement requires manpower, increasing both testing and time costs.

[0006] To address this, a pedal height measurement structure for detecting automotive pedal braking is proposed. Utility Model Content

This structure can solve the problem of measuring the movement data of the car brake pedal in some existing methods, especially in ordinary car repair shops, where measurements are taken manually by bending over and using a ruler. Manual measurement with a ruler is inefficient and easily affected by factors such as the operator's technique and reading errors, resulting in low measurement accuracy.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A pedal height measuring structure for detecting the braking of a car pedal includes a base plate 1, a measuring cylinder 2 on the top of the base plate 1, a movable rod 3 on the top of the measuring cylinder 2, clamping mechanisms 6 on both sides of the top of the movable rod 3, and a measuring mechanism 8 inside the measuring cylinder 2.

[0030] The measuring mechanism 8 includes a connecting line 801, several vent holes 802, several support columns 803, and a distance sensor 804. The front side of the connecting line 801 passes through the measuring cylinder 2 and is electrically connected to the output end of the distance sensor 804. The bottom of the distance sensor 804 is fixedly connected to the bottom of the inner wall of the measuring cylinder 2. The vent holes 802 are opened inside the measuring cylinder 2. The bottom of the support columns 803 is fixedly connected to the bottom of the inner wall of the measuring cylinder 2.

[0031] In this embodiment: First, the movable rod 3 is pulled out from inside the rotating sleeve 4, and the fixed frame 604 and fixed plate 5 are moved to the side of the brake pedal. The clamping column 601 is rotated, and the clamping plate 602 is moved down by the threaded connection. The anti-slip pad 603 is used to adhere to the car brake pedal to complete the clamping. Then, the movable rod 3 is inserted back into the rotating sleeve 4. The rotating sleeve 4 is rotatably connected to the fixed plate 5 via the first rotating frame 9, which facilitates the movable rod 3 to adapt to the arc-shaped movement trajectory of the car brake pedal. At this time, the anti-slip block 10 of the base plate 1 abuts against the vehicle body, providing both anti-slip and support, ensuring the stability of the measuring cylinder 2 and the movable rod 3. The measuring cylinder 2 is connected to the base plate 1 via the second rotating frame 7, which can flexibly adjust the angle when the testing personnel step on the brake pedal. When the pedal pushes the movable rod 3 to retract into the measuring cylinder 2, the distance sensor 804 is activated, which monitors the movement distance in real time. The data is transmitted to an external terminal for display via the connecting cable 801, showing the pedal depressing depth. This facilitates the detection and judgment of the car's braking system and solves the problem of measuring the movement data of the car's brake pedal in some existing methods, especially in ordinary car repair shops, where measurements are usually taken manually by bending over and using a ruler. Manual measurement with a ruler is inefficient and easily affected by factors such as the operator's operation and reading errors, resulting in low measurement accuracy. At the same time, manual measurement requires manpower, increasing the detection cost and time cost.

[0032] Specifically, such as Figure 4 As shown, the clamping mechanism 6 includes a clamping post 601, a clamping plate 602, an anti-slip pad 603, and a fixing frame 604. The clamping post 601 is threadedly connected to the inside of the fixing frame 604. The top of the clamping plate 602 is fixedly connected to the bottom of the clamping post 601, and the top of the anti-slip pad 603 is fixedly connected to the bottom of the clamping plate 602.

[0033] Specifically, such as Figure 1 As shown, a fixing plate 5 is fixedly installed on the top of the movable rod 3, and the bottom of the fixing frame 604 is fixedly connected to the top of the fixing plate 5.

[0034] Specifically, such as Figure 1 and Figure 5 As shown, the bottom of the fixed plate 5 is fixedly connected to the first rotating frame 9, and the inside of the first rotating frame 9 is rotatably connected to the rotating sleeve 4.

[0035] Specifically, such as Figure 2 and Figure 5As shown, the movable rod 3 is movably inserted into the inside of the rotating sleeve 4, and the top of the movable rod 3 is chamfered.

[0036] In this embodiment: the clamping column 601 is connected to the fixed frame 604 by a threaded connection. When the clamping column 601 rotates, it can move, which can easily drive the clamping plate 602 and the anti-slip pad 603 to move, so that the clamping plate 602 and the anti-slip pad 603 can stably clamp the car brake pedal. The base plate 1 can connect the two fixed frames 604 together. The rotating sleeve 4 is rotatably connected to the first rotating frame 9, so that the rotating sleeve 4 can rotate, which can facilitate the angle change of the movable rod 3, which can easily adapt to the arc-shaped downward trajectory when the car brake pedal is pressed. By opening a chamfer at the top of the movable rod 3, the movable rod 3 can be easily inserted into the rotating sleeve 4.

[0037] Specifically, such as Figure 1 and Figure 2 As shown, the movable rod 3 is movably inserted into the inside of the measuring cylinder 2, and there is damping at the insertion point between the movable rod 3 and the measuring cylinder 2.

[0038] Specifically, such as Figure 3 As shown, a second rotating frame 7 is rotatably mounted on the surface of the measuring cylinder 2, and the bottom of the second rotating frame 7 is fixedly connected to the top of the base plate 1.

[0039] Specifically, such as Figure 6 As shown, a number of anti-slip blocks 10 are fixedly connected to the bottom of the base plate 1, and the anti-slip blocks 10 are evenly distributed on the bottom of the base plate 1.

[0040] In this embodiment: due to the damping at the insertion point of the movable rod 3 and the measuring cylinder 2, the movable rod 3 moves smoothly and will not move arbitrarily, thus affecting the detection accuracy. By rotating the measuring cylinder 2 inside the second rotating frame 7, the measuring cylinder 2 can be easily rotated, and the angle of the measuring cylinder 2 can be easily changed to adapt to the arc trajectory when the car brake pedal moves down.

[0041] Working principle: By pulling the movable rod 3 out of the rotating sleeve 4, the fixing frame 604 and the fixing plate 5 are moved to the position between the car brake pedal and the opposite side of the fixing frame 604 and the fixing plate 5. Then, the clamping column 601 is rotated. Since the clamping column 601 is threadedly connected to the fixing frame 604, the rotation of the clamping column 601 drives the clamping plate 602 to move up and down until the anti-slip pad 603 at the bottom of the clamping plate 602 is tightly attached to the car brake pedal, achieving stable clamping. Then, the movable rod 3 is reinserted into the rotating sleeve 4, so that the movable rod 3 is fully inserted into the rotating sleeve 4. The rotating sleeve 4 is connected to the first rotating frame 9 and... The fixed plate 5 is rotatably connected, allowing the movable rod 3 to flexibly adjust its angle to accommodate the downward arc of the car brake pedal. At this time, the anti-slip block 10 at the bottom of the base plate 1 abuts against the car body at the bottom of the brake pedal, providing anti-slip and support, ensuring the stability of the measuring cylinder 2 and the movable rod 3 during measurement. The measuring cylinder 2 is connected to the top of the base plate 1 via a second rotating frame 7 that is rotatably fitted to its surface, facilitating adjustment of the measuring cylinder 2's angle and better coordination with the movable rod 3 for measurement. When the inspector presses the car brake pedal, the brake pedal pushes the movable rod 3 to retract into the measuring cylinder 2. Simultaneously, the control... The distance sensor 804 inside the measuring cylinder 2 starts working, monitoring the movement distance of the movable rod 3 in real time. The distance sensor 804 is electrically connected to an external terminal via the connecting cable 801, transmitting the measurement data to the external terminal for display, thus visually presenting the brake pedal movement data. The vent 802 inside the measuring cylinder 2 balances the air pressure inside, ensuring smooth movement of the movable rod 3. The support column 803 prevents the movable rod 3 from colliding with or squeezing the distance sensor 804. Damping exists at the connection point between the movable rod 3 and the measuring cylinder 2, ensuring smooth movement of the movable rod 3 and preventing it from moving arbitrarily, thus affecting the detection accuracy. The chamfer at the top of the movable rod 3 facilitates the insertion of the rotating sleeve 4. This solves the problem of measuring the movement data of the car brake pedal in some existing methods, especially in ordinary auto repair shops, where measurements are often done manually using rulers and bending over. Manual measurement with a ruler is inefficient and easily affected by the operator's technique and reading errors, resulting in low measurement accuracy. Furthermore, manual measurement requires manpower, increasing detection and time costs.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
