[0053] Implementation Method 1

[0054] Please refer to Figures 1 to 9As shown, a brake motor mounting structure is provided in an embodiment of the present invention, which includes a caliper housing 100, a controller housing 200, a motor housing 300 and a motor end cover 400, wherein the caliper housing 100 is used to install a brake assembly; the controller housing 200 is used to install a control module 12, and the controller housing 200 is detachably connected to the caliper housing 100; the motor housing 300 is used to install a stator assembly 500, and the motor housing 300 is arranged on a side of the caliper housing 100 facing the controller housing 200, and is integrated with the caliper housing 100; the motor end cover 400 is used to install a rotor assembly 600, and the motor end cover 400 is arranged on a side of the controller housing 200 facing the caliper housing 100, and is integrated with the controller housing 200; when the controller housing 200 and the caliper housing 100 are in a connected state, the motor end cover 400 is matched and connected with the motor housing 300.

[0055] On the whole, the brake motor mounting structure reduces the number of parts, reduces product weight, reduces product size envelope, and reduces product cost by integrating the motor housing 300 with the caliper housing 100 and the motor end cover 400 with the controller housing 200, thereby helping to reduce assembly steps, improve integration, and make subsequent maintenance more convenient.

[0056] And, if Figure 5 and Figure 6 In the embodiment shown, the stator assembly 500 is pre-installed on the motor housing 300, and the rotor assembly 600 is pre-installed on the motor end cover 400. When the caliper housing 100 is connected to the controller housing 200, the motor housing 300 and the motor end cover 400 can be matched and connected together with the caliper housing 100 and the controller housing 200, and the rotor assembly 600 is correspondingly plugged into the stator assembly 500, so that the motor can be assembled in one installation step, which significantly improves the installation efficiency.

[0058] In the embodiment of the present invention, the designer may adjust the detachable connection mode between the controller housing 200 and the caliper housing 100 according to the use requirements, and no specific limitation is made here.

[0059] In a feasible embodiment, a first connection portion is provided on the controller housing 200, and a second connection portion is provided on the caliper housing 100, and the first connection portion and the second connection portion are detachably connected via a connection member. Preferably, the connection member is a connection bolt.

[0060] Furthermore, the controller housing 200 is provided with a plurality of first connecting parts, and the caliper housing 100 is provided with a plurality of second connecting parts, and the first connecting parts and the second connecting parts are provided correspondingly. Accordingly, a plurality of connecting members are also provided correspondingly.

[0061] By cooperating with multiple first connection parts, multiple second connection parts and multiple connecting parts, multiple connection points can be formed between the controller housing 200 and the caliper housing 100, thereby synergistically improving the connection reliability of the controller housing 200 and the caliper housing 100.

[0062] Designers can adjust the specific structures of the first connection part and the second connection part according to the use requirements, and no specific restrictions are made here. Preferably, the first connection part and the second connection part are both configured as bolt holes.

[0063] More preferably, some of the first connecting parts are arranged around the motor end cover 400 at intervals, and correspondingly, some of the second connecting parts are arranged around the motor housing 300 at intervals, thereby helping to enhance the connection strength at the motor location and having better structural stability.

[0064] In another feasible embodiment, a first clamping structure is provided on the controller housing 200, and a second clamping structure is provided on the caliper housing 100, and the first clamping structure and the second clamping structure can be detachably clamped to each other.

[0065] Furthermore, a plurality of first clamping structures are provided, and a plurality of second clamping structures are correspondingly provided. By cooperating with a plurality of first clamping structures and a plurality of second clamping structures, a plurality of connection points can be formed between the controller housing 200 and the caliper housing 100, thereby synergistically improving the connection reliability of the controller housing 200 and the caliper housing 100.

[0066] Designers can adjust the specific structures of the first and second clamping structures according to usage requirements, and no specific restrictions are imposed herein. For example, the first and second clamping structures are respectively configured as a buckle and a clamping block; or the first and second clamping structures are respectively configured as a clamping block and a clamping slot.

[0067] In the embodiment of the present invention, the designer can adjust the specific shape of the motor housing 300 and the motor end cover 400 according to the use requirements, and no specific limitation is made here. Figure 5 and Figure 6In the illustrated embodiment, the motor housing 300 is substantially cylindrical, and the motor end cover 400 is substantially circular.

[0068] Of course, in other feasible embodiments, designers can adjust the specific shape and structure of the motor housing 300 and the motor end cover 400 according to usage requirements, and no specific limitation is made here.

[0069] In an embodiment of the present invention, Figure 2 and Figure 3 In the illustrated embodiment, the stator assembly 500 includes a stator winding 510 disposed in the motor housing 300, and the rotor assembly 600 includes a rotating shaft 610, and a rotor winding 620 and a driving gear 630 disposed on the rotating shaft 610. The rotating shaft 610 is rotatably connected to the motor end cover 400, and the driving gear 630 is used to connect to the power transmission mechanism 11; when the controller housing 200 and the caliper housing 100 are in a connected state, the rotor winding 620 is inserted into the stator winding 510.

[0070] By rotatably connecting the rotating shaft 610 with the motor end cover 400, the rotation stability of the rotor assembly 600 is ensured, and the transmission effect is improved. In addition, the stator winding 510 and the rotor winding 620 can generate power through cooperation, and the driving gear 630 on the rotating shaft 610 can transmit the power to the power transmission mechanism 11, thereby playing the role of driving the electric control brake 10.

[0071] Designers can adjust the specific structures of the stator winding 510 and the rotor winding 620 according to usage requirements, and no specific restrictions are made here.

[0072] Further, such as Figure 4 In the illustrated embodiment, the rotor assembly 600 further includes a first bearing 640 and a second bearing 650 disposed on the rotating shaft 610. The first bearing 640 and the second bearing 650 are relatively disposed on both sides of the rotor winding 620, and the second bearing 650 is located between the rotor winding 620 and the driving gear 630. The rotating shaft 610 is rotatably connected to the motor end cover 400 via the second bearing 650. When the controller housing 200 and the caliper housing 100 are in a connected state, the first bearing 640 is connected to the motor housing 300.

[0073] The first bearing 640 and the second bearing 650 are provided to improve the rotation accuracy and the load-bearing capacity of the rotating shaft 610 , reduce the friction and vibration noise during the rotation process, and improve the service life of the motor.

[0074] Designers can adjust the specific structures of the first bearing 640 and the second bearing 650 according to usage requirements, and no specific restrictions are made here.

[0075] In an embodiment of the present invention, Figure 5In the illustrated embodiment, a receiving groove 310 is formed on the motor housing 300 , and the first bearing 640 can be inserted into the receiving groove 310 .

[0076] By inserting the first bearing 640 into the receiving groove 310 , the installation accuracy and structural stability of the first bearing 640 are improved, thereby improving the rotation stability of the rotating shaft 610 .

[0077] Furthermore, by inserting the first bearing 640 into the receiving groove 310 , the first bearing 640 can be limited and the installation process can be simplified.

[0078] In an embodiment of the present invention, Figure 1 and Figure 3 In the embodiment shown, the brake motor mounting structure also includes a shielding end cover 210 disposed on the controller housing 200, the shielding end cover 210 is detachably connected to the controller housing 200, a transmission cavity is formed between the shielding end cover 210 and the controller housing 200, and the driving gear 630 is disposed in the transmission cavity.

[0079] By setting a shielding end cover 210 on the controller housing 200 and setting the driving gear 630 in the transmission cavity between the shielding end cover 210 and the controller housing 200, the driving gear 630 and the force transmission mechanism 11 can be protected to prevent external objects from entering the transmission cavity, thereby ensuring transmission stability.

[0080] Furthermore, by arranging the driving gear 630 and the force transmission mechanism 11 in the transmission cavity, the driving gear 630 and the force transmission mechanism 11 are isolated from the control module 12 to avoid mutual influence.

[0081] Furthermore, by making the shielding end cover 210 detachably connected to the controller housing 200, it is also convenient to remove the shielding end cover 210 to maintain and repair components such as the rotor assembly 600 and the power transmission mechanism 11, thereby improving the convenience of maintenance.

[0082] Designers can adjust the detachable connection method between the shielding end cover 210 and the controller housing 200 according to usage requirements, and no specific restrictions are made here.

[0083] For example, the shielding end cover 210 is detachably clamped on the controller housing 200. Alternatively, the shielding end cover 210 is detachably connected to the controller housing 200 through a connector. Alternatively, the shielding end cover 210 is threadedly connected to the controller housing 200. Alternatively, the shielding end cover 210 is bonded to the controller housing 200.

[0084] In an embodiment of the present invention, Figure 1 and Figure 3In the illustrated embodiment, the brake motor mounting structure further includes a position sensing module 700 disposed between the rotor assembly 600 and the control module 12 , and the position sensing module 700 is used to obtain a rotation position signal of the rotor assembly 600 .

[0085] The position sensing module 700 can more accurately obtain the rotation position signal of the rotor assembly 600, so that the control module 12 can more accurately know the operating status of the motor, thereby facilitating more accurate control of the braking stroke of the force transmission mechanism 11 and improving the braking effect.

[0086] Specifically, the position sensing module 700 includes an induction magnet 710 disposed on the rotor assembly 600, and a position sensor 720 for being disposed on the control module 12. The induction magnet 710 and the position sensor 720 are arranged at intervals along the axial direction of the rotor assembly 600. The induction magnet 710 can rotate with the rotor assembly 600. The position sensor 720 is used to obtain a rotation position signal of the rotor assembly 600 through the induction magnet 710. The position sensor 720 can be installed inside the controller housing 200 together with the control module 12.

[0087] By arranging the induction magnet 710 and the position sensor 720 at intervals along the axial direction of the rotor assembly 600, the induction magnet 710 can rotate coaxially with the rotor assembly 600. Therefore, by using the position sensor 720 to detect the position of the induction magnet 710, the rotation position of the rotor assembly 600 can be accurately obtained, thereby improving the position detection accuracy.

[0088] Furthermore, the control module 12 can better control the movement stroke of the motor based on the rotation position signal obtained by the position sensor 720, and further control the braking stroke of the force transmission mechanism 11, which is beneficial to improving the braking effect.

[0089] In an embodiment of the present invention, the brake motor mounting structure further includes a sealing structure 800 , the controller housing 200 and the caliper housing 100 are in a connected state, and the sealing structure 800 can be used to seal the motor housing 300 and the motor end cover 400 .

[0090] By providing the sealing structure 800 , the sealing reliability between the motor housing 300 and the motor end cover 400 can be ensured, and impurities and water can be prevented from entering the interior of the motor, so that the motor can operate more stably.

[0091] The designer can adjust the specific structure of the sealing structure 800 according to the use requirements, and no specific limitation is made here. Preferably, the sealing structure 800 includes a sealing gasket. The sealing gasket can be clamped between the motor housing 300 and the motor end cover 400 to play a sealing role.

[0092] More preferably, the sealing gasket is arranged around the motor housing 300 and the motor end cover 400. Specifically, as Figure 1 In the illustrated embodiment, when the caliper housing 100 and the controller housing 200 are in a connected state, a sealing gasket can be clamped between the caliper housing 100 and the controller housing 200 , and the sealing gasket can seal the caliper housing 100 and the controller housing 200 .

[0093] At the same time, since the sealing gasket is arranged around the motor housing 300 and the motor end cover 400, the sealing area formed by the sealing gasket can cover the motor housing 300 and the motor end cover 400, thereby ensuring the sealing of the motor.

[0094] In an embodiment of the present invention, the brake motor mounting structure further includes a controller end cover 900 , and the controller end cover 900 is connected to the controller housing 200 .

[0095] In a feasible embodiment, the controller end cover 900 is detachably connected to the controller housing 200. By making the controller end cover 900 detachably connected to the controller housing 200, it is convenient to better disassemble and install the controller end cover 900, and then install the control module 12 and other components to the controller housing 200, thereby improving the installation and maintenance efficiency.

[0096] Furthermore, the controller end cover 900 and the controller housing 200 can form a controller housing when connected together. The controller housing can play a protective role and prevent external dust and water from entering, thereby ensuring the operating stability of the control module 12 and other components.

[0097] In another feasible embodiment, the controller end cover 900 is fixedly connected to the controller housing 200. By making the controller end cover 900 and the controller housing 200 fixedly connected, the connection reliability of the controller end cover 900 and the controller housing 200 is improved.

[0098] Designers can adjust the connection method between the controller end cover 900 and the controller housing 200 according to usage requirements, and no specific restrictions are made here.

[0099] For example, the controller end cover 900 is snap-fitted to the controller housing 200. Alternatively, the controller end cover 900 is connected to the controller housing 200 via a connector. Alternatively, the controller end cover 900 is connected to the controller housing 200 via a thread. Alternatively, the controller end cover 900 is bonded to the controller housing 200. In the embodiment of the present invention, Fig. 9 In the illustrated embodiment, the brake motor mounting structure further includes a limiting structure 410 disposed on the motor end cover 400 , and the limiting structure 410 can limit the second bearing 650 axially and the outer ring of the second bearing 650 circumferentially.

[0100] The limiting structure 410 can provide axial limiting function for the second bearing 650 , so that the second bearing 650 can bear axial forces in two directions in the axial direction, thereby preventing the rotor assembly 600 from accidentally falling, thereby improving the installation stability of the rotor assembly 600 .

[0101] When the brake motor is in severe working conditions such as vibration and shock, the vibration and shock are easily transmitted to the brake motor mounting structure, thereby causing the outer ring of the second bearing 650 to rotate on the motor end cover 400, causing the outer ring of the second bearing 650 to run in circles and fail.

[0102] In order to solve the above problem, the limiting structure 410 in the present invention can also limit the outer ring of the second bearing 650 in the circumferential direction. The limiting structure 410 limits the outer ring of the second bearing 650 in the circumferential direction, thereby preventing the outer ring of the second bearing 650 from rotating on the motor end cover 400, thereby preventing the second bearing 650 from failing due to circumferential movement.

[0103] In a feasible embodiment, a plug-in through hole for installing the rotor assembly 600 is provided on the motor end cover 400, and the second bearing 650 is arranged in the plug-in through hole. The limiting structure 410 includes a first limiting portion 411 and a second limiting portion 412 protruding from the plug-in through hole. The first limiting portion 411 and the second limiting portion 412 are respectively arranged on both sides of the second bearing 650 and abut against the outer ring of the second bearing 650.

[0104] The outer ring of the second bearing 650 can be limited in the plug-in through hole by the first limiting portion 411 and the second limiting portion 412, and the first limiting portion 411 and the second limiting portion 412 respectively abut against the two sides of the outer ring of the second bearing 650. The first limiting portion 411 and the second limiting portion 412 can clamp the outer ring of the second bearing 650, so as to limit the outer ring of the second bearing 650 in the circumferential direction, thereby avoiding the problem of failure of the outer ring of the second bearing 650 due to rotation on the motor end cover 400.

[0105] Further, the first limiting portion 411 is integrally provided with the motor end cover 400; and / or, the second limiting portion 412 is integrally provided with the motor end cover 400. Preferably, the first limiting portion 411 is integrally provided with the motor end cover 400; and, the second limiting portion 412 is integrally provided with the motor end cover 400.

[0106] By integrally arranging the first limiting portion 411 and the motor end cover 400 and the second limiting portion 412 and the motor end cover 400, the structural strength of the first limiting portion 411 and the second limiting portion 412 is improved, the number of parts is reduced, and better use effect is achieved.

[0107] Designers can adjust the specific shapes of the first limiting portion 411 and the second limiting portion 412 according to usage requirements, and no specific restrictions are imposed herein. Preferably, the first limiting portion 411 and the second limiting portion 412 are configured in a ring shape.

[0108] Of course, in other feasible embodiments, designers can adjust the specific structure of the limiting structure 410 according to the use requirements, and no specific limitation is made here. For example, the limiting structure 410 fixes the outer ring of the second bearing 650 in the plug-in through hole by riveting or snap spring connection.
