Description

Technical Field

[0001] This utility model relates to the field of automotive braking system maintenance and repair technology, and more specifically, it relates to an adjustable brake block. Background Technology

[0002] In the field of automotive braking system maintenance and repair, adjusting and replacing the brake pads is a crucial step in ensuring braking performance. Traditional brake pad mounting structures often require specialized tools for tedious adjustments when changing the distance between the brake pads and brake discs. This is not only complex and time-consuming but also prone to inaccuracies. Especially under different operating conditions, due to variations in brake disc wear, frequent adjustments to the brake pad position are necessary to ensure optimal braking performance. Existing adjustment methods struggle to meet the demands for rapid and precise adjustments, severely impacting maintenance efficiency and the performance of the braking system.

[0003] With the rapid growth of car ownership and the continuous improvement of maintenance requirements, the limitations of traditional brake pad installation methods have become increasingly apparent. Existing brake pad installation structures typically use bolt fixing, requiring the removal of multiple fasteners when replacing brake pads. This not only increases the workload of maintenance personnel but also prolongs maintenance time. Furthermore, due to the complexity of the installation structure, repeated disassembly and reassembly can easily cause damage or loss of parts, increasing maintenance costs and potentially affecting the reliability of the braking system due to improper installation. These problems severely restrict the improvement of automotive maintenance efficiency and increase safety hazards during the maintenance process. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides an adjustable brake block, which has the following advantages:

[0017] 1. The quick-installation mechanism provides a stable foundation through the fixed connection between the mounting plate and the housing. The plug-in design between the sleeve and the mounting plate enables quick installation. The limiting sleeve inside the mounting sleeve provides a reliable guide for the slider. The locking block at the top of the slider can automatically engage with the slot on the outer wall of the sleeve under the action of the push spring, achieving quick locking. The sliding connection between the positioning slot and the positioning block ensures the accuracy of the installation process. The cooperative design of the sliding sleeve and the unlocking block, through the interaction of the rounded corners, enables convenient unlocking operation. The design of the polygonal locking block prevents rotation at the connection point and improves the stability of the overall structure. This quick-installation design greatly improves the efficiency of brake block replacement and solves the problems of cumbersome replacement and unreliable fixation in traditional devices.

[0018] 2. The adjustment mechanism adopts an innovative combination design. The sliding connection between the connecting sleeve and the insert sleeve provides basic support. The cooperation between the rotating sleeve and the central rod realizes the transmission of rotational motion. The spiral groove on the outer wall of the central rod and the adapter block inside the insert sleeve form a precise motion conversion mechanism, converting rotational motion into linear motion, thus realizing the precise adjustment of the brake block position. The design of two sets of spiral grooves enhances the stability and accuracy of adjustment. This adjustment mechanism design is not only easy to operate, but also enables precise control of the brake block position, effectively solving the problems of inconvenient adjustment and low precision of traditional devices.

[0019] 3. The positioning mechanism achieves reliable position locking through the precise cooperation between the locking block and the locking groove, combined with the elastic effect of the return spring. The sliding design of the lock sleeve and the cooperation of the force spring provide a convenient unlocking method. When the lock sleeve moves, it can compress the force spring and push the locking block out of the locking groove through the return spring, allowing the rotating sleeve to rotate freely for adjustment. The multi-set distribution design enhances the stability of positioning. This positioning mechanism design not only ensures the operational safety of the adjustment mechanism, but also provides a convenient unlocking method, effectively solving the problems of inaccurate positioning and inconvenient operation in traditional devices, and significantly improving the reliability and ease of operation of the entire device.

[0029] Please see Figures 1-5 An adjustable brake block 4 includes a brake assembly 1, a housing 2 on the brake assembly 1, and a quick-release mechanism on the housing 2. The quick-release mechanism includes a mounting plate 3, a brake block 4, a sleeve 5, a slot 6, a mounting sleeve 7, a limiting sleeve 8, a slider 9, a locking block 10, a push spring 11, a sliding sleeve 12, an unlocking block 13, and a stop block 14. The mounting plate 3 is installed inside the housing 2, the brake block 4 is located inside the mounting plate 3, the sleeve 5 is inserted into the mounting plate 3, multiple sets of slots 6 are distributed on the outer wall of the sleeve 5, the mounting sleeve 7 is installed inside the brake block 4, multiple sets of limiting sleeves 8 are installed on the inner wall of the mounting sleeve 7, the slider 9 slides within multiple sets of limiting sleeves 8, and the locking block 10 is installed within multiple sets of limiting sleeves 8. At the top of the slider 9, a push spring 11 is installed on the top surface of multiple sets of locking blocks 10. A sliding sleeve 12 slides on the bottom of the mounting sleeve 7. Multiple unlocking blocks 13 are installed on the top surface of the sliding sleeve 12. A stop block 14 is installed on the bottom surface of multiple sets of locking blocks 10. An adjustment mechanism is provided on the insert sleeve 5. The adjustment mechanism includes a connecting sleeve 15, a rotating sleeve 16, a central rod 17, a spiral groove 18, and an adapter block 19. The connecting sleeve 15 is fixedly installed on the mounting plate 3 and slidably connected to the insert sleeve 5. The rotating sleeve 16 is rotatably installed on the top of the connecting sleeve 15. The central rod 17 is installed inside the rotating sleeve 16. The spiral groove 18 is located on the outer wall of the central rod 17. The adapter block 19 is installed inside the insert sleeve 5 and slidably connected to the spiral groove 18.

[0030] The outer wall of the insert sleeve 5 is provided with a positioning groove 20, and the inner side of the mounting sleeve 7 is provided with a positioning block 21. The positioning groove 20 and the positioning block 21 are provided in multiple sets and are slidably connected. The working principle is that when the insert sleeve 5 is inserted into the mounting sleeve 7, the positioning block 21 will slide along the positioning groove 20. The setting of multiple positioning structures ensures accurate positioning during the insertion process, prevents the insert sleeve 5 from deflecting or rotating, and improves the installation accuracy and stability of the entire quick-installation mechanism.

[0031] Multiple sets of locking blocks 10 are all polygonal and are slidably connected to multiple sets of limiting sleeves 8. The working principle of this structure is that the polygonal design prevents the locking blocks 10 from rotating during the movement, ensuring that the locking blocks 10 always maintain the correct working position. At the same time, the sliding connection with the limiting sleeves 8 provides stable guiding support, improving the reliability and accuracy of the locking mechanism.

[0032] The top of the multiple unlocking blocks 13 and the bottom of the abutment blocks 14 are all provided with rounded corners. The working principle is that when the sliding sleeve 12 moves, the rounded corners of the unlocking blocks 13 and the rounded corners of the bottom of the abutment blocks 14 slide against each other, reducing contact friction and impact, making the unlocking action smoother and more efficient, while also reducing the wear of the components and extending the service life of the mechanism.

[0033] The mounting sleeve 7 is equipped with a reset spring 22. The two ends of the reset spring 22 are connected to the mounting sleeve 7 and the sliding sleeve 12 respectively. The working principle of this design is that when the sliding sleeve 12 completes the unlocking action, the reset spring 22 will generate a rebound force, automatically pulling the sliding sleeve 12 back to the initial position, ensuring the automatic reset function of the unlocking mechanism and improving the convenience and reliability of operation.

[0034] The spiral groove 18 and the mating block are both provided in two sets and are slidably connected. The working principle is that when the center rod 17 rotates, the sliding connection between the two sets of spiral grooves 18 and the mating block converts the rotational motion into linear motion. The dual-set design increases the stability and load-bearing capacity of the motion, ensuring the accuracy and smoothness of the adjustment process.

[0035] In this embodiment, when the brake block 4 needs to be installed, the insert 5 is inserted into the mounting plate 3. Multiple sets of limiting sleeves 8 within the mounting sleeve 7 provide guidance for the slider 9. The locking block 10 at the top of the slider 9 automatically engages with the slot 6 on the outer wall of the insert 5 under the action of the push spring 11, achieving rapid locking. The sliding connection between the positioning groove 20 and the positioning block 21 ensures the accuracy of the insertion process. When disassembly is required, the sliding sleeve 12 slides at the bottom of the mounting sleeve 7, causing the unlocking block 13 to move upwards. The rounded corner design of the unlocking block 13 matches the rounded corner at the bottom of the abutment block 14. The interaction pushes the polygonal locking block 10 out of the slot 6, and unlocks it under the action of the return spring 22. The sliding connection between the connecting sleeve 15 and the insert sleeve 5 provides basic support. When it is necessary to adjust the position of the brake block 4, the rotating sleeve 16 is rotated, which drives the internal central rod 17 to rotate. The two sets of spiral grooves 18 on the outer wall of the central rod 17 slide and cooperate with the adapter block 19 in the insert sleeve 5, converting the rotational motion into linear motion, thereby realizing the precise displacement of the insert sleeve 5. This design not only ensures the accuracy of adjustment, but also provides stable support.

[0036] Please see Figures 4-5 As one implementation of the positioning mechanism: the connecting sleeve 15 is provided with a positioning mechanism, which includes a locking block 23, a locking groove 24, a return spring 25 and a locking sleeve 26. The locking block 23 is provided with multiple sets of sliding installations on the rotating sleeve 16. The locking groove 24 is provided with multiple sets distributed on the outer wall of the connecting sleeve 15. The return spring 25 is provided with multiple sets of installations on multiple sets of locking blocks 23 and connected to the outer wall of the rotating sleeve 16. The locking sleeve 26 slides on the outer wall of the connecting sleeve 15.

[0037] A force-applying spring 27 is provided between the connecting sleeve 15 and the locking sleeve 26. The working principle of this design is that the force-applying spring 27 provides continuous pressure to the locking sleeve 26, keeping the locking block 23 in the locked position. When unlocking is required, the operator needs to overcome the force of the force-applying spring 27 to move the locking sleeve 26 to unlock. After release, the locking sleeve 26 automatically returns to its original position under the action of the force-applying spring 27, ensuring the reliability of the positioning mechanism and the automatic reset function.

[0038] More specifically, the force spring 27 pushes the locking sleeve 26 to slide along the connecting sleeve 15 and abuts against the top of multiple sets of locking blocks 23, locking them into the locking groove 24. At the same time, it compresses multiple sets of return springs 25 to complete the locking of the rotating sleeve 16. When adjustment is required, the locking sleeve 26 moves to compress the force spring 27, and the multiple sets of return springs 25 elastically push the locking blocks 23 out of the locking groove 24, allowing the rotating sleeve 16 to rotate for adjustment.

[0039] In summary, during use or operation of the overall equipment: when the brake block 4 needs to be installed, the insert sleeve 5 is inserted into the mounting plate 3. The multiple sets of limiting sleeves 8 inside the mounting sleeve 7 provide guidance for the slider 9. The locking block 10 at the top of the slider 9 automatically engages with the slot 6 on the outer wall of the insert sleeve 5 under the action of the push spring 11, achieving quick locking. The sliding connection between the positioning groove 20 and the positioning block 21 ensures the accuracy of the insertion process. When disassembly is required, the sliding sleeve 12 slides at the bottom of the mounting sleeve 7, driving the unlocking block 13 to move upward. The rounded corner design of the unlocking block 13 and the bottom of the abutment block 14... The rounded corners of the ends interact to push the polygonal locking block 10 out of the locking slot 6, and unlocking is completed under the action of the return spring 22. The sliding connection between the connecting sleeve 15 and the insert sleeve 5 provides basic support. When it is necessary to adjust the position of the brake block 4, the rotating sleeve 16 is rotated, which drives the internal central rod 17 to rotate. The two sets of spiral grooves 18 on the outer wall of the central rod 17 slide and cooperate with the adapter block 19 in the insert sleeve 5, converting the rotational motion into linear motion, thereby realizing the precise displacement of the insert sleeve 5. This design not only ensures the accuracy of adjustment, but also provides stable support.

[0040] The force spring 27 pushes the locking sleeve 26 to slide along the connecting sleeve 15 and abuts against the top of multiple sets of locking blocks 23, locking them into the locking groove 24. At the same time, it compresses multiple sets of return springs 25 to complete the locking of the rotating sleeve 16. When adjustment is required, the locking sleeve 26 moves to compress the force spring 27, and the multiple sets of return springs 25 elastically push the locking blocks 23 out of the locking groove 24, allowing the rotating sleeve 16 to rotate for adjustment.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
