Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a motor stator quick-disassembly structure used in an automobile brake system. Background Art

[0002] In modern cars, especially those equipped with electronic brake assist systems, motors are widely used as key components in brake systems. The traditional motor stator installation structure is relatively complex and requires professional tools and a long time to disassemble and assemble, which not only increases the difficulty of maintenance but also prolongs the maintenance cycle. Therefore, it is particularly important to develop a motor stator structure that can be quickly disassembled and assembled. Utility Model Content

[0003] The utility model aims to provide a motor stator quick-disassembly structure for automobile brake system, which has the advantages of simple structure, convenient and quick installation and disassembly, and improved automobile repair and maintenance efficiency, thus solving the problems in the prior art.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A motor stator quick-release structure for an automobile brake system comprises a motor housing, a partition plate is provided inside the motor housing, a base is mounted on the partition plate via a support plate, a first rotating shaft passes longitudinally through the base, a three-leaf cam is fixed to the middle of the first rotating shaft, a clamping assembly is provided on the outer wall of the base, a through hole is also provided on the outer wall of the base, a push rod passes through the through hole, one end of the push rod abuts against the side wall of the three-leaf cam, and the other end of the push rod abuts against the clamping assembly.

[0006] Preferably, the snap-in components are arranged in no less than three groups and are evenly distributed on the side wall of the motor housing.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. When installing the utility model, the push block is pushed to drive the lever to rotate, and the lever drives the first rotating shaft and the three-leaf cam to rotate. The side wall of the three-leaf cam gradually squeezes the push rod during the rotation process to make it move out of the motor housing, and the push rod pushes the bottom side of the claw outward. Under the action of the lever, the upper side of the claw approaches the direction of the stator until the top hook of the claw presses the bottom edge of the stator against the top surface of the base. At this time, the closed sub-buckle on one side of the push block is inserted into the closed female buckle to fix the position of the push block; when disassembling, the closed female buckle and the closed sub-buckle are opened, and the push block is pushed to restore the claw to its original position. After the claw is out of contact with the stator, the stator can be removed, which simplifies the disassembly and assembly process of the stator, achieves a quick disassembly effect, and effectively improves the efficiency and convenience of automobile maintenance.

[0013] 2. The utility model aligns the positioning hole at the bottom of the stator with the first rotating shaft and inserts it, so that the stator contacts the top surface of the base. The top of the first rotating shaft plays the role of a positioning pin, ensuring the accuracy of the stator installation and avoiding performance problems caused by improper installation.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to solve the problems of complex stator installation structure, inconvenient disassembly and low efficiency of automobile repair and maintenance in the prior art, the following technical solutions are provided. Please refer to Figure 1-6 ;

[0023] A motor stator quick-release structure for an automobile brake system comprises a motor housing 1, a partition plate 2 is provided inside the motor housing 1, a base 4 is mounted on the partition plate 2 via a support plate 3, a first rotating shaft 5 is longitudinally passed through the base 4, a three-leaf cam 6 is fixed to the middle of the first rotating shaft 5, a clamping assembly is provided on the outer side wall of the base 4, a through hole 7 is also provided on the outer side wall of the base 4, a push rod 8 is passed through the through hole 7, one end of the push rod 8 is abutted against the side wall of the three-leaf cam 6, and the other end of the push rod 8 is abutted against the clamping assembly.

[0024] The clamping components are arranged in no less than three groups and are evenly distributed on the side wall of the motor housing 1 .

[0025] The clamping assembly includes a clamping claw 9, a pivot plate 10 and a return spring 11. A second rotating shaft 12 is provided in the middle of the clamping claw 9, and pivot plates 10 are provided at both ends of the second rotating shaft 12. The second rotating shaft 12 is rotatably connected to the base 4 through the pivot plates 10. The bottom of the side of the clamping claw 9 facing the base 4 is in contact with the push rod 8, and the upper part of the side of the clamping claw 9 facing the base 4 is connected to the side wall of the base 4 through the return spring 11. When the clamping claw 9 is fully opened, the push rod 8 abuts against the concave part of the side wall of the three-leaf cam 6. When the three-leaf cam 6 is rotated, the distance between its side wall and the side wall of the motor housing 1 gradually decreases, thereby continuously pushing the push rod 8 to the outside.

[0026] The upper and lower ends of the first rotating shaft 5 pass through the base 4, and the first rotating shaft 5 is rotatably connected to the top and bottom surfaces of the base 4. The part passing through the top of the first rotating shaft 5 can play the role of a positioning pin. The first rotating shaft 5 cooperates with the positioning hole in the middle of the stator 18. During installation, the positioning hole of the stator 18 is aligned with the first rotating shaft 5 for connection, thereby ensuring the position accuracy of the stator 18 during installation, and at the same time making it difficult for the stator 18 to deviate on the base 4 after installation; the lower end of the first rotating shaft 5 is fixedly connected to the shift rod 13.

[0027] A movable through slot 14 is formed on the side wall of the motor housing 1 , and the first rotating shaft 5 passes through the movable through slot 14 . A push block 15 is fixed to the outer end of the first rotating shaft 5 .

[0028] Both ends of the movable through slot 14 are provided with closing female buckles 16 , and the closing female buckles 16 cooperate with the closing sub-buckles 17 provided on both sides of the push block 15 .

[0029] Specifically, during installation, align the positioning hole at the bottom of the stator 18 with the first rotating shaft 5 and insert it so that the stator 18 contacts the top surface of the base 4, push the push block 15 to drive the lever 13 to rotate, the lever 13 drives the first rotating shaft 5 to rotate, and the first rotating shaft 5 drives the three-leaf cam 6 to rotate. The side wall of the three-leaf cam 6 gradually squeezes the push rod 8 during the rotation process to move it out of the motor housing 1, and the push rod 8 pushes the bottom side of the claw 9 outward. Under the action of the lever, the upper side of the claw 9 approaches the direction of the stator 18 until the top hook of the claw 9 presses the bottom edge of the stator 18 against the top surface of the base 4. At this time, the closed sub-buckle 17 on one side of the push block 15 is inserted into the closed female buckle 16 to fix the position of the push block 15.

[0030] Working principle: When disassembling, open the closed female buckle 16 and the closed sub-buckle 17, and the staff pushes the push block 15 to return to its original position. The claw 9 is reset under the action of the reset spring 11, and the push rod 8 is pushed back into the motor housing 1. After the claw 9 rotates and breaks away from the contact with the stator 18, the stator 18 can be removed to achieve a quick release effect.
