Detailed Implementation

[0017] The exemplary embodiments disclosed in this application will now be described in more detail. Numerous specific details are set forth in the following description to provide a more thorough understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without one or more of these details. In other instances, to avoid confusion with this application, some technical features well-known in the art have not been described; that is, not all features of actual embodiments are described herein, nor are well-known functions and structures described in detail.

[0018] Please refer to Figures 1-4As shown in the preferred embodiment of this application, a brake detection device is used to detect the braking force of a brake assembly 6. The detection system includes a worktable 1, a mounting base 2, a power supply assembly 3, a pressure plate assembly 4, a data acquisition unit, and a control assembly 5. The mounting base 2 is mounted on the worktable 1 and is used to mount the brake assembly 6. The power supply assembly 3 provides power to the brake assembly 6 to switch it from an initial state to a braking state. The pressure plate assembly 4 can move relative to the mounting base 2 under external force and is configured to apply force to the abutment portion 621 of the brake assembly 6 in the braking state. The data acquisition unit is connected to the pressure plate assembly 4 and includes a pressure sensor mounted on the pressure plate assembly 4 and a displacement sensor located between the pressure plate assembly 4 and the brake assembly 6. The data acquisition unit collects contact data between the pressure plate assembly 4 and the brake assembly 6, including the pressure value of the pressure plate assembly 4 and the displacement value of the brake assembly 6. The control assembly 5 is connected to the data acquisition unit and receives the data collected by the acquisition unit.

[0019] In this embodiment, two mounting bases 2 are provided, with at least two mounting bases 2 installed on the workbench 1 along the first direction. These mounting bases 2 are suitable for mounting at least two specifications of brake assemblies 6, thereby eliminating the need to change testing equipment or perform cumbersome adjustments when testing the braking force of brake assemblies 6 of various specifications. This improves the versatility and flexibility of the brake testing device and increases testing efficiency. In this embodiment, the specifications of the two brake assemblies 6 are 10 inches and 12 inches, respectively. In other embodiments, the specifications of the brake assemblies 6 are not specifically limited; they can be set according to specific testing requirements.

[0020] Specifically, the brake assembly 6 includes a brake body 61 and a hub cover 62 fitted onto the brake body 61. A supporting portion 621 is located on the hub cover 62. When the force applied to the supporting portion 621 by the pressure pad assembly 4 exceeds a first preset value, the hub cover 62 drives the brake body 61 to move. This first preset value is the braking force that the brake assembly 6 needs to measure. The brake body 61 is a conventional drum brake, including brake shoes and a brake drum mounted on the hub cover 62. When the brake body 61 is energized, the brake shoes will press and rub against the brake drum, achieving braking of the hub cover 62.

[0021] Understandably, by providing a hub cover 62 and having a support portion 621 located on the hub cover 62, the support portion 621 can be a protrusion formed on the hub cover 62. The pressure pad assembly 4 does not directly contact the brake body 61, but indirectly applies driving force to the brake drum of the brake body 61 by applying pressure to the hub cover 62, and detects the braking force of the brake shoes on the brake drum through heat detection, thereby preventing the brake body 61 from directly contacting the pressure pad assembly 4 and causing wear. On the other hand, by indirectly detecting the braking force of the brake body 61 by providing a hub cover 62, even if the hub cover 62 deforms due to large force, it can be directly disassembled and replaced without affecting the brake body 61.

[0022] More specifically, the brake body 61 is provided with a number of bolts 611 evenly spaced along its circumference, and the hub cover 62 is provided with through holes 622 adapted to the bolts 611. The bolts 611 pass through the through holes 622 respectively, and the fasteners 612 fix the hub cover 62 to the brake body 61. The advantage of this arrangement is that the fasteners 612 can ensure the stability of the connection between the brake body 61 and the hub cover 62, and the number of bolts 611 passing through the through holes 622 can facilitate the operator to quickly and accurately install the hub cover 62 onto the brake body 61, and can also distribute the connection force between the hub cover 62 and the brake body 61 to multiple points. This means that when the brake assembly 6 is subjected to a large force during the braking force test, the distributed force can better resist the pressure of the pressure pad assembly 4, reducing the risk of loosening or damage to the connection due to excessive local force.

[0023] In this embodiment, the pressing assembly 4 includes a pressing structure 41 for abutting against the supporting part 621, and a first driving member 42, a second driving member 43, and a third driving member 44 connected to the pressing structure 41. The first driving member 42 drives the pressing structure 41 to move in a first direction, the second driving member 43 drives the pressing structure 41 to move in a second direction, and the third driving member 44 drives the pressing structure 41 to move in a third direction. This allows the pressing structure 41 to more flexibly adjust its relative position and the direction of force with the supporting part 621 of the brake assembly 6 to adapt to the testing requirements of brake assemblies 6 of different specifications. In this embodiment, the first direction is the front-back direction, the second direction is the left-right direction, and the third direction is the up-down direction.

[0024] In this embodiment, the third driving member 44 includes a driving motor 441 and a lead screw component 442. The lead screw component 442 connects the driving motor 441 and the pressing structure 41. The lead screw component 442 is used to convert the rotational motion of the driving motor 441 into the linear motion of the pressing structure 41, so as to realize the up and down movement of the pressing structure 41 and the application of force to the supporting part 621.

[0025] The tablet compression assembly 4 also includes a first slide rail 45, a second slide rail 46 and a third slide rail 47. The first drive member 42 can move along the first slide rail 45 in a first direction, the second drive member 43 can move along the second slide rail 46 in a second direction, and the third drive member 44 can move along the third slide rail 47 in a third direction.

[0026] In this embodiment, the tablet pressing structure 41 includes a connecting plate 411 and a pressing plate 412 connected to the connecting plate 411. The connecting plate 411 is connected to the lead screw component 442, and the pressing plate 412 is used to abut against the supporting part 621. The connecting plate 411 and the pressing plate 412 are integrally formed to improve the overall strength and stability of the tablet pressing structure 41. During the testing process, when the tablet pressing structure 41 is subjected to a large force, the integrally formed connecting plate 411 and the pressing plate 412 can better bear and transmit the force, reducing deformation or damage caused by insufficient structural strength, thereby ensuring that the tablet pressing structure 41 can work stably for a long time and improving the reliability and service life of the testing system.

[0027] In this embodiment, the system also includes an alarm unit, which is connected to the control component 5 and the displacement sensor respectively. When the displacement sensor detects a change in the displacement value of the brake component 6, the control component 5 can promptly transmit a signal to the alarm unit, which then issues an alarm to remind the operator to take timely measures to prevent the pressing structure 41 from applying excessive force to the supporting part 621, which could cause the pressing structure 41 to slip off from the supporting part 621 and damage the detection equipment. This ensures the safety and reliability of the detection process and improves the overall performance and safety of the detection system.

[0028] In this embodiment, the mounting base 2 is also provided with a quick connector 21 that connects to the power supply component 3. The quick connector 21 has an interface for plugging in the wires of the brake component 6, so as to avoid the need for a cumbersome connection process when testing the braking force of the brake component 6. The wire connection can be completed by simple plugging and unplugging, which greatly improves the connection efficiency between the brake component 6 and the power supply component 3 and saves preparation time and labor costs before testing.

[0029] In summary, the working process of this detection system is as follows: First, at least two different specifications of brake components are installed on the mounting base. Then, the hub cover is installed on the brake body. The wires on the brake body are connected to the quick connector so that the power supply component supplies power to the brake body. The brake shoes of the brake body open, generating braking force. At this time, the brake body cannot be rotated manually. Then, the first and second driving components drive the pressure plate structure to move to the vicinity of the brake body to be tested, specifically, the pressure plate structure moves to directly above the supporting part. The third driving component drives the pressure plate structure to move downward until it abuts against the supporting part. The third driving component continues to drive the pressure plate structure to press down until the force applied by the pressure plate structure to the supporting part is greater than the first preset value. When the supporting part presses down, it causes the brake body to rotate counterclockwise. The pressure sensor and displacement sensor transmit the pressure and displacement data of the first preset value to the control component, respectively. At the same time, the alarm unit sounds an alarm, which reminds the staff to take action.

[0030] The above is only one specific implementation of this application, and any other improvements made based on the concept of this application shall be considered within the scope of protection of this application.
