Description

Technical Field

[0001] The present application relates to the technical field of brakes, and in particular to a wireless alarm device for detecting shoe wear. Background Art

[0002] A brake is a device that has the function of slowing down, stopping or keeping a moving part (or moving machinery) in a stopped state. It is a mechanical part that stops or slows down the moving parts in a machine. It is commonly known as a brake or gate. The basic components of a brake are horseshoes and friction plates arranged on the outside of the horseshoes. Braking is achieved by the force between the friction plates and the brake pads. After the brake is used for too long, the friction plates will wear. Once the wear exceeds the safety value, the braking effect will be poor, which is dangerous to use.

[0003] In the related art, in order to prevent the friction plate from wearing beyond the safety value, a wear alarm is usually installed on the brake to remind the user to replace the friction plate in time when it is worn. Regardless of whether it is a disc brake or a drum brake, the wear alarm adopts an external sensor line mode, that is, the signal transmission process adopts wired transmission. This traditional wired transmission will inevitably cause wear during the driving of the vehicle. Severe cases will cause damage to the wear alarm line, thereby causing the alarm function to be abnormal, resulting in the vehicle being unable to alarm in time when the shoe is consumed, which in turn causes brake failure, resulting in greater harm and consequences.

[0028] See also Figures 1 to 5 The present application exemplarily provides a wireless alarm device for detecting shoe wear, comprising:

[0029] A detection seat 1 is provided with a mounting hole and a groove 16, the groove 16 forms an indication window, a plurality of bosses 17 are provided on the groove 16, the bosses 17 are spaced apart and form indication positions, a first detection element is provided on any boss 17, a snap-fit ​​member 15 is further provided on the groove 16, the snap-fit ​​member 15 is movably provided on the indication window, and a second detection element is provided on the snap-fit ​​member 15;

[0030] A driving member 13 is rotatably arranged on the mounting hole and connected to the camshaft 2. The driving member 13 can rotate on the detection seat 1 following the camshaft 2. A push rod 14 is also arranged on the driving member 13. One end of the push rod 14 is connected to the detection seat 1, and the other end extends toward the indication window and contacts the buckle 15. The push rod 14 pushes the buckle 15 to move on the indication window.

[0031] The signal receiver sends out an alarm signal when the first detection element is in contact with the second detection element. The signal receiver receives the alarm signal and sends out an alarm.

[0032] In the wireless alarm device for detecting shoe wear provided in the present application, a first detection element is arranged on the boss 17. During braking, the camshaft 2 rotates, the driving member 13 rotates following the camshaft 2, and the push rod 14 pushes the latch 15 to move on the indication window. As the shoe wears, the rotation angle of the camshaft 2 gradually increases, and the push rod 14 pushes the latch 15 to gradually approach the boss 17 where the first detection element is located. When the latch 15 reaches the boss 17 where the first detection element is located, the second detection element on the latch 15 contacts the first detection element and sends out an alarm signal. The alarm signal is received by a signal receiver and an alarm is issued, so as to timely remind the user that the shoe wear has reached a critical value and to replace the shoe in time. By transmitting the alarm signal wirelessly, the line is not easily damaged, thereby ensuring the normal use of the alarm function. In addition, the movement of the latch 15 on the indication window allows the shoe wear to be checked through the indication window, which is convenient for inspecting and repairing the brake.

[0033] In this example, see Figure 2 and Figure 5 The buckle 15 blocks the movement path of the push rod 14, and the two ends of the buckle 15 contact the side walls of the groove 16. The buckle 15 is provided with a blocking portion 20 on the side away from the push rod 14, and the blocking portion 20 extends into the interval. Specifically, the driving member 13 is a disc structure, and a snap is provided on the driving member 13. The driving member 13 is connected to one end of the camshaft 2 through the snap. The camshaft 2 rotates, driving the driving member 13 to rotate, and the push rod 14 pushes the buckle 15 to move. The side of the blocking portion 20 away from the push rod 14 is an inclined surface 21. When the push rod 14 thrusts, The inclined surface 21 will give way, so that the latch 15 moves in the direction of the boss 17 where the first detection element is located. When the push rod 14 is reset, the latch 15 will not be reset with the push rod 14 due to the blocking portion 20 extending into the gap between the bosses 17. Instead, the latch 15 will be stuck between the two bosses 17 at the current position, and an indication will be formed on the indication window for the user to check the wear of the shoe. As the shoe wears, the rotation angle of the camshaft 2 will gradually increase, the distance moved by the push rod 14 will continue to increase, and the latch 15 will continue to approach the boss 17 where the first detection element is located.

[0034] In this embodiment, the first detection element and the second detection element are sensing chips. After the sensing chips come into contact, a wireless circuit is formed to send out an alarm signal. The alarm signal is transmitted to the signal receiver through the wireless circuit. Compared with the existing wired signal transmission, the alarm signal is transmitted wirelessly, and the alarm circuit will not be damaged, thereby ensuring the normal use of the shoe wear alarm function.

[0035] In this embodiment, if Figure 3 and Figure 4As shown, the wireless alarm device for detecting shoe wear also includes: a brake member 4, which is connected to the camshaft 2. The brake member 4 has a rotationally symmetrically arranged bending portion to form an S-shaped structure. Specifically, one end of the camshaft 2 is connected to the driving member 13, and the other end is connected to the brake member 4. During braking, the camshaft 2 rotates, driving the driving member 13 and the brake member 4 to rotate at the same time. The brake member 4 rotates for braking, and the driving member 13 rotates for detection.

[0036] In this embodiment, the wireless alarm device for detecting shoe wear also includes: a brake seat 12, which is arranged on the wheel hub 3, a brake member 4 is arranged on the brake seat 12, and the camshaft 2 passes through the brake seat 12 and is connected to the brake member 4. Specifically, the bottom of the wheel hub 3 is adapted to the brake seat 12, and the brake seat 12 is assembled in the wheel hub 3 and connected to the bottom of the wheel hub 3.

[0037] In this embodiment, the wireless alarm device for detecting shoe wear also includes: a brake shoe, which is relatively arranged in the circumference of the brake seat 12, and the brake shoe includes a mounting plate 8 and a connecting plate 7. The mounting plate 8 is an arc-shaped structure matching the inner wall of the wheel hub 3, and the connecting plates 7 are provided in two. The connecting plates 7 are connected to the side of the mounting plate 8 away from the wheel hub 3, and there is a gap between the connecting plates 7. Specifically, the connecting plates 7 are an arc-shaped structure matching the circumference of the brake seat 12. The brake shoe is connected to the brake seat 12 through the connecting plates 7. By providing two connecting plates 7, the stability of the overall structure of the mounting plate 8 can be enhanced, and the length of the connecting plates 7 is greater than the length of the mounting plate 8.

[0038] In some embodiments, a mounting position for installing a brake shoe is provided on the brake seat 12, one end of the connecting plate 7 extends into the mounting position, and a connecting member 19 is also provided on the mounting position. The connecting member 19 passes through the mounting position and the connecting plate 7 in sequence, and the brake shoe is rotated and set on the mounting position. The other end of the connecting plate 7 is set close to the bending portion of the brake member 4. When the brake member 4 rotates, the bending portion contacts the connecting plate 7, pushing the connecting plate 7, so that the connecting plate 7 rotates on the brake seat 12, thereby making the mounting plate 8 close to the inner wall of the wheel hub 3.

[0039] In the above embodiment, a braking portion 5 is provided between the connecting plates 7 at one end close to the braking member 4, and the braking portion 5 matches the bending portion of the braking member 4. Specifically, the braking portion 5 is a columnar structure connected between the connecting plates 7. When the braking member 4 rotates, the bending portion approaches the braking portion 5 and pushes the braking portion 5, thereby realizing the rotation of the connecting plate 7 on the brake seat 12.

[0040] In this embodiment, a first reinforcing rib 18 is further provided between the connecting plates 7, and a second reinforcing rib 10 is provided between the connecting plate 7 and the mounting plate 8. The structural strength between the connecting plate 7 and the mounting plate 8 is improved by the first reinforcing rib 18 and the second reinforcing rib 10. An elastic member 6 is further provided between the brake shoes, and a mounting column 11 for mounting the elastic member 6 is further provided between the connecting plates 7. Both ends of the elastic member 6 are hung on the mounting column 11 to connect the brake shoes. Specifically, both ends of the elastic member 6 have hook portions, and the elastic member 6 is hung on the mounting column 11 by the hook portions. The elastic member 6 is a reset spring.

[0041] In the above embodiment, a friction plate 9 is provided on the side of the mounting plate 8 close to the wheel hub 3. During braking, the camshaft 2 rotates to drive the brake member 4 to rotate. The bent portion of the brake member 4 approaches the brake portion 5 and pushes the brake portion 5 to make the brake shoe close to the wheel hub 3. The braking is performed by the friction between the friction plate 9 and the inner wall of the wheel hub 3. At this time, the elastic member 6 is stretched by force. After the braking is completed, the camshaft 2 resets and rotates, the brake member 4 resets, and the elastic member 6 resets to pull the brake shoe back away from the wheel hub 3, thereby completing the reset of the brake shoe.

[0042] It should be noted that, during the braking process, the camshaft 2 rotates, and the brake member 4 rotates accordingly, so that the brake shoe approaches the wheel hub 3, and the friction plate 9 rubs against the wheel hub 3 to achieve braking. During long-term use, the friction plate 9 will be worn. As the friction plate 9 is worn and consumed, the angle at which the camshaft 2 drives the brake member 4 to rotate will gradually increase. When the wear and consumption of the friction plate 9 exceeds the braking safety value, it means that the angle at which the camshaft 2 drives the brake member 4 to rotate has reached the maximum. The moving distance of the push rod 14 on the driving member 13 will follow the change in the rotation angle of the brake member 4. According to the maximum rotation angle of the brake member 4, at the corresponding cam A first detection element is arranged on the platform 17, and an initial position of the snap member 15 is between two bosses 17 close to the push rod 14. As the friction plate 9 is worn and consumed, the angle at which the camshaft 2 drives the brake member 4 to rotate gradually increases, and the push rod 14 on the driving member 13 pushes the snap member 15 to approach the boss 17 where the first detection element is located. When the wear and consumption of the friction plate 9 exceeds the braking safety value, the snap member 15 is pushed by the push rod 14 to reach the boss 17 where the first detection element is located, and the first detection element contacts the second detection element and sends out an alarm signal, which means that the friction plate 9 on the brake shoe needs to be replaced in time, thereby realizing the wear alarm reminder function.

[0043] In summary, in the wireless alarm device for detecting shoe wear provided in the present application, a first detection element is arranged on the boss 17. During braking, the camshaft 2 rotates, the driving member 13 rotates following the camshaft 2, and the push rod 14 pushes the latch 15 to move on the indication window. As the shoe wears, the rotation angle of the camshaft 2 gradually increases, and the push rod 14 pushes the latch 15 to gradually approach the boss 17 where the first detection element is located. When the latch 15 reaches the boss 17 where the first detection element is located, the second detection element on the latch 15 contacts the first detection element and sends out an alarm signal. The alarm signal is received by a signal receiver and an alarm is issued, so as to promptly remind the user that the shoe wear has reached a critical value and the shoe is replaced in time. By transmitting the alarm signal wirelessly, the line is not easily damaged, thereby ensuring the normal use of the alarm function. In addition, the movement of the latch 15 on the indication window allows the shoe wear to be checked through the indication window, which is convenient for inspecting and repairing the brake.
