Description

Technical Field

[0001] This utility model belongs to the field of automotive brake testing technology, and more specifically, it relates to a loading-type brake testing device. Background Technology

[0002] With the continuous increase in the number of cars on the road, the safety of automotive braking systems has become increasingly important, making loaded brake testing equipment a key device for ensuring that automotive braking performance meets standards. Existing loaded brake testing equipment mainly consists of a mounting base, a lifting mechanism, and a roller testing platform. The mounting base needs to be pre-fixed and embedded in the testing position, with structural stability ensured through concrete pouring or bolt anchoring, providing a stable benchmark for subsequent loaded testing. During testing, the vehicle to be tested drives onto the roller assembly of the roller testing platform, and the lifting mechanism is immediately activated, hydraulically or electrically lifting it to a preset height so that the wheels are fully in contact with the roller surface. Subsequently, the roller testing platform actively applies a loading force, simulating the braking conditions of a vehicle in motion through roller transmission, simultaneously collecting key parameters such as braking force and wheel speed, ultimately completing a precise test and evaluation of the braking system performance.

[0003] Existing application number CN202420547543.4 discloses a vehicle loading brake platform, relating to the technical field of vehicle testing equipment. It includes a support frame; a bracket, which is slidably connected to the support frame; a roller drive assembly, mounted on the bracket, for contacting and driving the two front wheels or two rear wheels of the vehicle; a torque detection assembly, mounted on the bracket, for detecting torque changes in the roller drive assembly; a processor, electrically connected to the torque detection assembly, for calculating the vehicle's braking performance parameters; and a lifting drive assembly, mounted on the support frame, for driving the bracket and roller drive assembly to rise. This vehicle loading brake platform can simulate the load conditions a vehicle experiences during actual driving and measure the vehicle's braking performance parameters under load.

[0004] Based on the above, in existing loading-type brake testing equipment, the mounting base and roller testing platform are usually flush with the ground, while in some equipment the roller testing platform is slightly higher than the mounting base, forming a small step structure. During testing, the wheel must roll directly over the metal frame of the mounting base and roller testing platform to enter the testing roller and complete the loading test. However, the metal frame is subjected to the rolling pressure of the wheel for a long time, especially with heavy vehicles, and is prone to deformation due to overload; moreover, the frame replacement and maintenance process is complex, not only time-consuming but also increasing operation and maintenance costs. More importantly, if the vehicle's direction of travel deviates during operation, the wheel is very likely to accidentally press on the inspection covers on both sides and the middle of the upper part of the roller testing platform, causing deformation and damage to the inspection covers, further increasing the risk of equipment failure and subsequent maintenance pressure. Utility Model Content

[0005] To address the aforementioned technical problems, this invention provides a loading-type brake testing device. In existing loading-type brake testing devices, the mounting base and roller testing platform are typically flush with the ground, while in some devices the roller testing platform is slightly higher than the mounting base, forming a small step structure. During testing, the wheel must roll directly over the metal frame of the mounting base and roller testing platform to enter the testing roller and complete the loading test. However, the metal frame, subjected to the rolling pressure of the wheel over a long period, is prone to deformation due to overload, especially with heavy vehicles. Furthermore, frame replacement and maintenance are complex, time-consuming, and increase maintenance costs. More importantly, if the vehicle's direction deviates during operation, the wheel is highly likely to accidentally press against the inspection covers on the upper sides and center of the roller testing platform, causing deformation and damage to the covers, further exacerbating the risk of equipment failure and subsequent maintenance burden.

The testing platform is slidably connected inside the mounting base. The side inspection covers are bolted to the left and right sides of the testing platform. The central inspection cover is bolted to the center of the testing platform, and the front and rear sides of the central inspection cover have chamfered edges. Four sets of metal inclined platforms are provided, and the four sets of metal inclined platforms are located on the upper part of the mounting base. Four sets of sound-emitting boards are provided, and the four sets of sound-emitting boards are located on the upper part of the mounting base. The maintenance component is located on the upper part of the mounting base. The warning component is located on the upper part of the mounting base.

[0007] Furthermore, the maintenance components include: mounting slots and rubber ramps. There are four sets of mounting slots, which are located on the upper part of the mounting base. Four sets of metal ramps are slidably connected inside the four sets of mounting slots. There are two sets of rubber ramps, which are bolted to the upper part of the mounting base.

[0008] Furthermore, the maintenance components also include: bridge-type protective plates and curved chamfers. Two sets of bridge-type protective plates are provided, and the two sets of bridge-type protective plates are snapped onto the upper part of two sets of side inspection covers. Two sets of curved chamfers are provided, and the two sets of curved chamfers are opened on the inner side of the two sets of bridge-type protective plates.

[0009] Furthermore, the warning component includes: guide rods and reset springs. There are four sets of guide rods, which are slidably connected inside four sets of mounting slots, and the tops of the four sets of guide rods are fixedly connected to the bottom of the four sets of metal inclined platforms. There are four sets of reset springs, which are fixedly installed in the middle of the four sets of metal inclined platforms and the mounting slots.

[0010] Furthermore, the warning component also includes: a trigger switch, a warning slot, and a speaker. There are four sets of trigger switches, which are fixedly installed inside the four sets of mounting slots. There are four sets of warning slots, which are opened on the upper part of the mounting base. Four speaker panels are fixedly installed on the top of the four sets of warning slots. There are four sets of speakers, which are fixedly installed inside the four sets of warning slots. The speakers and trigger switches are connected together through wiring harnesses and power supply to form a switching circuit.

[0011] Furthermore, the warning assembly also includes: a drive rack, a lead screw, and a driven gear. There are four sets of drive racks, which are fixedly installed on one side of four sets of metal inclined platforms. There are four sets of lead screws, which are rotatably connected inside the mounting base. There are four sets of driven gears, which are coaxially fixedly installed on one end of the four sets of lead screws. The driven gears and drive racks mesh with each other.

[0012] Furthermore, the warning assembly also includes: guide rails, sealing plates, and transmission plates.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Firstly, this utility model features a maintenance component that connects the mounting base and the inspection platform via a rubber ramp. Utilizing the elastic buffering properties of rubber, it reduces the impact on the metal frame when a wheel enters, minimizing deformation caused by long-term rolling, especially from heavy vehicles. Simultaneously, the rubber ramp is low-cost and easy to install and disassemble, significantly reducing subsequent maintenance and replacement time and costs. Combined with a bridge-type protective plate covering the side inspection cover, it prevents the inspection cover from being directly crushed and deformed when the wheel is misaligned. Furthermore, the curved chamfer on the inner side of the protective plate enhances its load-bearing capacity and prevents the right-angled edge from cutting the tire, balancing equipment protection and vehicle safety. The pre-set chamfer on the central inspection cover further strengthens its structure, acting as a buffer against accidentally approaching wheels and reducing the risk of damage to the inspection cover.

[0014] Secondly, this utility model has a warning component. The metal inclined platform slides under force to trigger a switch, which causes the speaker to quickly emit a warning sound, promptly reminding the driver to adjust the driving direction and avoid the vehicle continuing to deviate and causing a collision with the equipment. At the same time, the sliding of the metal inclined platform drives the transmission mechanism to operate, aligning the sealing plate with the hole of the speaker plate, ensuring that the warning sound is transmitted without obstruction and improving the warning effect. Under normal conditions, the reset spring pushes the sealing plate to seal the hole of the speaker plate, which can prevent impurities and stones from entering the warning slot and damaging the speaker, ensuring the long-term stable operation of the component.

[0015] This utility model has the advantages of safety protection, convenient maintenance, and timely warning. It not only solves the problems of easy deformation of the metal frame, easy damage of the inspection cover, and high maintenance cost of existing equipment, but also avoids the risk of vehicle deflection through real-time early warning, thus improving the overall durability, safety and ease of operation and maintenance of the equipment.

Detailed Implementation

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] Example 1: As attached Figure 1 To be continued Figure 6 As shown: This utility model provides a loading-type brake testing device, including a mounting base 1, a testing platform 2, side inspection covers 3, a central inspection cover 4, a metal inclined platform 5, a sound-emitting plate 6, and maintenance components. The testing platform 2 is slidably connected inside the mounting base 1; the side inspection covers 3 are bolted to the left and right sides of the testing platform 2; the central inspection cover 4 is bolted to the middle of the testing platform 2, and the front and rear sides of the central inspection cover 4 are provided with inclined chamfers; four sets of metal inclined platforms 5 are provided, and the four sets of metal inclined platforms 5 are provided on the upper part of the mounting base 1; four sets of sound-emitting plates 6 are provided, and the four sets of sound-emitting plates 6 are provided on the upper part of the mounting base 1; the maintenance components are provided on the upper part of the mounting base 1.

[0025] The maintenance components include: mounting slots 101 and rubber inclined platforms 8. There are four sets of mounting slots 101, which are opened on the upper part of the mounting base 1. Four sets of metal inclined platforms 5 are slidably connected inside the four sets of mounting slots 101. There are two sets of rubber inclined platforms 8, which are bolted to the upper part of the mounting base 1.

[0026] The maintenance components also include: a bridge-type protective plate 301 and an arc-shaped chamfer 302. Two sets of bridge-type protective plates 301 are provided, and the two sets of bridge-type protective plates 301 are snapped onto the upper part of two sets of side inspection covers 3. Two sets of arc-shaped chamfers 302 are provided, and the two sets of arc-shaped chamfers 302 are opened on the inner side of the two sets of bridge-type protective plates 301.

[0027] The specific usage and function of this embodiment are as follows: During equipment operation, the rubber ramp 8 serves as the connecting structure between the mounting base 1 and the testing platform 2. On one hand, its elastic properties as rubber material buffer and dampen the impact of vehicles entering the testing area, effectively reducing the impact of the wheels on the metal frame of the mounting base 1 and the testing platform 2, and reducing deformation and wear of the frame due to long-term stress. On the other hand, the rubber ramp 8 is low-cost, easy to install and disassemble, and requires no complicated operations for subsequent maintenance and replacement, significantly reducing operation and maintenance costs. When a vehicle deviates from its course or may mistakenly enter a non-testing area, the metal ramp 5 can guide and buffer the wheels through its ramp structure. It utilizes the high strength of the metal material to withstand instantaneous impact forces. Since the metal ramp 5 is only triggered when the vehicle deviates, its daily usage frequency is low, and the metal structure can further extend its service life, avoiding frequent replacements. If the vehicle deviates significantly and the wheel approaches the side access cover 3, the bridge-type protective plate 301, which is attached to the upper part of the side access cover 3, can directly provide physical protection for the access cover, preventing the wheel from directly running over it and causing deformation. Simultaneously, the arc-shaped chamfer 302 on the inner side of the bridge-type protective plate 301 optimizes the structural stress performance and enhances the load-bearing capacity of the protective plate itself, while also preventing the right-angled edge from cutting damage to the tire, thus balancing equipment protection and vehicle safety. Furthermore, the pre-set beveled chamfers on the front and rear sides of the central access cover 4 enhance the structural load-bearing capacity of the access cover itself and act as a buffer against accidentally approaching wheels, preventing deformation of the access cover due to direct force and further ensuring the stability of the core components of the equipment.

[0028] Example 2: Based on Example 1, such as Figures 1 to 6 As shown, it also includes: a warning component, which is disposed on the upper part of the mounting base 1.

[0029] The warning component includes: guide rods 501 and reset springs 502. Four sets of guide rods 501 are provided, and the four sets of guide rods 501 are slidably connected inside the four sets of mounting slots 101. The tops of the four sets of guide rods 501 are fixedly connected to the bottoms of the four sets of metal inclined platforms 5. Four sets of reset springs 502 are provided, and the four sets of reset springs 502 are fixedly installed in the middle position between the four sets of metal inclined platforms 5 and the mounting slots 101.

[0030] The warning component also includes: a trigger switch 1011, a warning slot 102, and a speaker 7. There are four sets of trigger switches 1011, which are fixedly installed inside the four sets of mounting slots 101. There are four sets of warning slots 102, which are opened on the upper part of the mounting base 1. Four sets of speaker panels 6 are fixedly installed on the top of the four sets of warning slots 102. There are four sets of speakers 7, which are fixedly installed inside the four sets of warning slots 102. The speakers 7 and the trigger switches 1011 are connected together by a wiring harness and a power supply to form a switching circuit.

[0031] The warning assembly also includes: a drive rack 503, a threaded screw 504, and a driven gear 5041. There are four sets of drive racks 503, which are fixedly installed on one side of four sets of metal inclined platforms 5. There are four sets of threaded screws 504, which are rotatably connected inside the mounting base 1. There are four sets of driven gears 5041, which are coaxially fixedly installed on one end of the four sets of threaded screws 504. The driven gears 5041 and the drive racks 503 mesh with each other.

[0032] The warning assembly also includes: guide rails 601, blocking plates 602, and transmission plates 603. Four sets of guide rails 601 are provided, and the four sets of guide rails 601 are fixedly installed at the bottom of four sets of speaker plates 6. Four sets of blocking plates 602 are provided, and the four sets of blocking plates 602 are slidably connected inside the four sets of guide rails 601. Four sets of transmission plates 603 are provided, and the four sets of transmission plates 603 are fixedly connected to the bottom of the four sets of blocking plates 602. The four sets of transmission plates 603 are threadedly connected to one end of four sets of threaded screws 504.

[0033] The specific usage and function of this embodiment are as follows: When the vehicle veers off course or risks entering an undetected area, the wheels will first contact the metal ramp 5. Under pressure, the metal ramp 5 slides downwards along the mounting groove 101, simultaneously compressing the return spring 502. During this process, the guide rod 501 restricts the sliding trajectory of the metal ramp 5, preventing it from deviating or jamming. When the metal ramp 5 slides to the bottom of the mounting groove 101, it triggers a preset trigger switch 1011. The trigger switch 1011 connects to the power supply via a switching circuit, causing the speaker 7 in the warning groove 102 to immediately emit a warning sound, quickly reminding the driver to adjust the driving direction and avoid collision risks. Simultaneously, the sliding of the metal ramp 5 synchronously drives the drive rack 503 on one side to move downwards. The drive rack 503, through tooth meshing, drives the driven gear 5041 to rotate, thereby driving the coaxial threaded screw 504 to rotate. The threaded screw 504 uses threaded transmission to drive the transmission plate 603 at the bottom to move horizontally. The transmission plate 603 then pulls the sealing plate 602 to slide along the guide rail 601, so that the sealing plate 602 is completely aligned with the sound-transmitting hole of the speaker plate 6, ensuring that the warning sound of the speaker 7 is transmitted without obstruction and improving the warning effect.

[0034] When the equipment is idle or undergoing normal testing, the reset spring 502, due to its own elastic tension, pushes the metal inclined platform 5 back to its initial height. At the same time, it drives the sealing plate 602 to move back through the transmission mechanism, resealing the holes in the speaker plate 6. This effectively prevents impurities and stones splashed during the testing process from entering the warning slot 102, avoiding damage to the speaker 7 and ensuring the long-term stable operation of the warning component.

[0035] The following points should be noted in this article: 1. The accompanying drawings of this embodiment only involve the structures involved in this embodiment; other structures can refer to the general design.

[0036] 2. Where there is no conflict, this embodiment and the features in the embodiment can be combined with each other to obtain new embodiments.
