Description

Technical Field

[0001] This utility model relates to the field of automotive teaching technology, specifically to a device for demonstrating the effect of anti-lock braking in automobiles. Background Technology

[0002] As a core technology for active safety in modern automobiles, the working principle of the anti-lock braking system involves multiple disciplines such as mechanics, electronics, and hydraulics.

[0003] The anti-lock braking system (ABS) monitors the rotational speed of each wheel in real time using wheel speed sensors. When the system detects that a wheel is about to lock up (usually determined by the rate of change in rotational speed), the electronic control unit (ECU) activates an adjuster within 0.1 seconds, dynamically adjusting the braking force at a frequency of 6-12 times per second. This pulse-type braking method keeps the tires at the critical state of maximum static friction, reducing braking distance on dry roads by 10%-20% compared to traditional braking systems, with even more significant improvements in braking performance on wet and slippery roads.

[0004] In the classroom, when teachers teach students about the anti-lock braking system (ABS) of automobiles, they usually do so through electronic screen demonstrations or verbal descriptions. However, students cannot intuitively understand the effect of the ABS on-site. In order to more intuitively show students the effect of the ABS, a demonstration device for the ABS effect is needed.

[0025] 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.

[0026] Example 1:

[0027] A vehicle anti-lock braking system (ABS) effect demonstration device, such as Figure 1-4 As shown:

[0028] It includes a base plate 1, a first side plate 2 vertically fixed to the left end of the base plate 1, and a second side plate 3 vertically fixed to the right end of the base plate 1. Two guide ropes 4 in a taut state are provided between the first side plate 2 and the second side plate 3. The two guide ropes 4 are arranged in parallel and relatively parallel to the base plate 1.

[0029] The first model car 51 is equipped with an anti-lock braking system (ABS), while the second model car 52 is not. Both the first model car 51 and the second model car 52 can be remote-controlled vehicles. Users can wirelessly control the braking of the first model car 51 and the second model car 52. The first model car 51 and the second model car 52 have through holes. One guide rope 4 passes through the through hole of the first model car 51 in a straight line, and the other guide rope 4 passes through the through hole of the second model car 52 in a straight line. The outer diameter of the guide rope 4 is smaller than the inner diameter of the through hole.

[0030] Two sets of parallel display panels 7 are provided on the upper surface of the base plate 1. The upper surfaces of the base plate 1 and the display panels 7 are flush. The display panels 7 are located below the corresponding guide ropes 4. The wheels of the first model car 51 and the second model car 52 roll relative to each other on the upper surfaces of the base plate 1 and the display panels 7. The display panels 7 can be made of blackboard, whiteboard, glass, etc.

[0031] A feeding assembly 6 is provided on the right side of the base plate 1, and the feeding assembly 6 is located between the first side plate 2 and the second side plate 3. The feeding assembly 6 includes a pigment tank 61 opened on the upper surface of the base plate 1. Two sets of feeding rollers 62 are rotatably connected in parallel within each set of pigment tanks 61. The outer surface of the feeding rollers 62 is uniformly textured. One end of one set of feeding rollers 62 is rotated manually or by a motor. The two sets of feeding rollers 62 are connected by a gear set 63 to achieve synchronous rotation. The pigment tank 61 is filled with pigment. The pigment can be water-soluble pigment, talcum powder, chalk powder, or other materials that can temporarily adhere to the wheels. When the first model car 51 and the second model car 52 brake, the pigment will fall off the wheels due to friction, forming more noticeable marks. The highest point of the feeding rollers 62 is roughly parallel to the upper surface of the base plate 1.

[0032] A baffle 9 is vertically slidably connected to the upper right side of the base plate 1 via a guide rod and guide block assembly 91. The baffle 9 is located on the side of the feeding assembly 6 away from the second side plate 3.

[0033] The front and rear side walls of the base plate 1 are provided with sliding grooves 11, and a slider 12 is slidably connected in the sliding grooves 11. The slider 12 and the wiper 8 are connected by an anti-detachment rope 81.

[0034] The display panel 7, the wiper 8, and the paint are used together; for example, the display panel 7 can be a blackboard, the wiper 8 can be a blackboard eraser, and the paint can be chalk powder; or the display panel 7 can be a whiteboard, the wiper 8 can be a sponge (used with alcohol), and the paint can be water-soluble paint; the wiper 8 is used to wipe off the paint adhering to the display panel 7.

[0035] It also includes a lid that can close the top opening of the paint tank 61 when not in use.

[0036] Working principle:

[0037] Guided by the guide rope 4, the first model car 51 is moved to the corresponding feeding component 6 position, so that the wheels of the first model car 51 are placed on the two sets of feeding rollers 62 and abut against each other. The two sets of feeding rollers 62 rotate to attach the pigment in the pigment tank 61 to it, and then transfer it to the wheels of the first model car 51, so as to temporarily apply pigment to the surface of the wheels of the first model car 51; the second model car 52 is similar and will not be described in detail.

[0038] The first model car 51 and the second model car 52 are controlled to move at the same speed by wireless remote control. At this time, the baffle 9 is relatively close to the bottom plate 1, and the baffle 9 simultaneously blocks the first model car 51 and the second model car 52 from moving forward. At this time, the first model car 51 and the second model car 52 are relatively positioned on the corresponding display plate 7.

[0039] Then, manually drag the baffle 9 upwards away from the base plate 1, so that the baffle 9 and the base plate 1 form a sufficient gap for the first model car 51 and the second model car 52 to pass through. The first model car 51 and the second model car 52 move forward a short distance without restriction. At the same time, the first model car 51 and the second model car 52 are braked simultaneously via wireless remote control. During this process, the buffer layer 21 of the first side plate 2 (which can be made of rubber) can prevent the first model car 51 and the second model car 52 from rigidly colliding with the first side plate 2 due to improper operation.

[0040] During the braking process of the first model car 51 and the second model car 52, paint on their wheels leaves marks on their respective display panels 7. This allows for the experimentation of the difference in braking performance between the first model car 51, which has an anti-lock braking system, and the second model car 52, which does not.

[0041] The guide rope 4 allows the first model car 51 and the second model car 52 to move in a straight line on the base plate, avoiding deviation.

[0042] In subsequent experiments, the traces left on the display panel 7 are wiped off by the wiper 8. The wiper 8 is prevented from being lost by the flexible anti-detachment rope 81. The anti-detachment rope 81 can compensate for the short length of the anti-detachment rope 81 and the long length of the base plate 1 by moving within the slide groove 11 through the slider 12. The wheels of the first model car 51 and the second model car 52 are temporarily coated with paint again by the feeding assembly 6.

[0043] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
